Emerging from [[Eleventh Doctor|his previous incarnation]]'s explosive [[regeneration]] on [[Trenzalore]], the '''Twelfth Doctor''' was the first incarnation of the Doctor's second regeneration cycle, bestowed upon him by the [[Time Lord]]s at [[Clara Oswald]]'s urging.


Assured of the survival of [[Gallifrey]], the Doctor was no longer chained down by guilt, becoming a less amiable character with a withdrawn attitude who habitually questioned his own goodness. Although he was no stranger to kindness and humour, the Twelfth Doctor often dispensed with niceties in a tense situation, becoming cold and calculative in critical moments that required sound judgment and the occasional application of sharp practice.
== History ==
After he sent his [[companion]] [[Clara Oswald]] away due to her betrayal, the Doctor spent centuries searching the universe for [[Gallifrey]], until he gave up in despair and found the city of the [[Voord]]. After years among them, they offered him leadership of the group mind. The Doctor accepted and, upon joining them, began to remember the [[continuity bomb]] and how he was responsible for the ordeal surrounding it.  


However, because of his detachment from emotions, he could come off as unpleasant, fearsome, and ruthless. He became harder to trust, and acknowledged his shift toward negative personality traits, feeling incensed and fearful at what he was changing into. However, after resolving his morality crisis, he started to show his lighter side more clearly and started to show the more positive traits of his character, until Clara's death caused him to return to his more cynical nature. After having his memory of her removed, however, the Doctor's jovial side mixed into his cynical nature to form a stable personality.
Leaving the clues that got him there, the alternate Doctor waited on [[Marinus]] for his past self, along with his [[Tenth Doctor|tenth incarnation]] and [[Eleventh Doctor|eleventh incarnations]] and their companions, and then fired upon them to direct them towards the continuity bomb.


Due to her being initially upset at him changing, the Doctor found more strain in his relationship with Clara, especially when she was dating [[Danny Pink]], a former soldier turned Maths teacher, whom the Doctor shared a mutual dislike of each other. However, he later found respect for Danny after he chose to sacrifice himself to stop a [[Cyberman (Mondas)|Cyberman]] invasion brought on by {{Gomez}}. Though he and Clara parted afterwards, the Doctor decided to renew their friendship after experiencing a dream of a possible future where Clara ended up old and alone.  
[[File:Four Doctors Alternate Twelfth Doctor 3.jpg|thumb|left|The Doctor's plan begins. ([[COMIC]]: ''[[Four Doctors (comic story)|Four Doctors]]'')]]
After they arrived in his timeline, the alternate Doctor took them to the Voord city, where he revealed himself as both the Voord leader and the mastermind behind the continuity bomb.  


During a revelation of where his face originated from, the Doctor decided to resurrect [[Ashildr]], a Viking girl who had died protecting her village from the [[Mire]], by using Mire technology to bring her back to life. However, in doing so, the Doctor ended up inadvertently making Ashildr immortal, forcing her to live through countless centuries while everyone around her died, giving her a jaded look on life. After an encounter with Ashildr in an alien refugee camp ended with Clara's death, the Doctor was transported to a tower that was designed to terrify him into confessing the identity of the Hybrid. After 4.5 billion years, during which time he repeatedly burned his old body to load a copy of himself at the moment of his arrival from the transporter's hard drive, the Doctor broke free of the trap and passed through a portal back to his home planet Gallifrey, where he overthrew [[Rassilon]] for presidency to save Clara, but ultimately lost his memory of her and was left to solitude.
Immediately taking the TARDIS and handcuffing the six, the alternate Doctor explained how the Voord hid from the [[Siege of Trenzalore]], and how he had maneuvered the events with the bomb into motion. He explained his plans to wipe their memories and lead to Voord to conquer the universe and become the new [[Time Lord]]s. However, the three Doctors instigated a struggle that allowed [[Alice Obiefune]] and [[Gabby Gonzalez]] to escape. The alternate Doctor then took Clara and the three Doctors to a device called the Conscience, to have their memories altered.


The Doctor was later reunited with his wife River Song; though she spent most of their adventure unaware of his identity, due to thinking his predecessor was the final incarnation. He then spent the night at [[Darillium]] with River that he had avoided numerous times before, enjoying twenty-four years with her before she left for [[the Library]]. The Doctor then took River's assistant, [[Nardole]], with him as a companion.
As he gloated about his victory, Alice was killed by his Voord guards and Gabby began to frantically open the Doctor's comics in the hope they could help her. Much to her horror, inside the bundle was a miniature [[Weeping Angel]], which grew to full size and sent her back in her own personal timeline to the [[café]] before the three Doctors arrived to greet their companions. Gabby warned the companions of what would occur if things went they way they had before, before fading from existence. ([[COMIC]]: ''[[Four Doctors (comic story)|Four Doctors]]'')


With Nardole in tow, the Doctor found himself guarding a vault at [[St Luke's University]], and gave up his travels to take a teaching job at the University, until he started tutoring [[Bill Potts]].
=== A new timeline ===
Now prepared for his alternate self's deceptions, the original Twelfth Doctor led his past incarnations and their companions to [[Marinus]] to deliberately set of the [[continuity bomb]] and enter the Voord city through [[River Song's World]]. Once there, the Twelfth Doctor entered the Voord group mind, and was confronted by the alternate Doctor.  


== Biography ==
The alternate Doctor was able to overpower his younger self, until the Twelfth Doctor called in the Tenth and Eleventh Doctors to assist him. Learning that the Doctors had sabotaged the city's force field, the alternate Doctor surrendered and was erased from existence after Clara apologised for her future betrayal. ([[COMIC]]: ''[[Four Doctors]]'')
=== Foreshadowing ===
When the [[Eleventh Doctor]] was attacked by [[the Then and the Now]] on [[Lujhimene]], the Twelfth Doctor was among the faces seen as the Doctor's timeline was almost destroyed. ([[COMIC]]: ''[[Running to Stay Still (comic story)|Running to Stay Still]]'')


During a visit to a [[Meta-fiction universe|parallel universe]] where he was a fictional character in a television series, the [[Eleventh Doctor]] told his portrayer, [[Matt Smith (The Girl Who Loved Doctor Who)|Matt Smith]], that [[Peter Capaldi (The Girl Who Loved Doctor Who)|Peter Capaldi]], whom he had previously rescued from a [[Mandrel]], would be a good choice to play him on the show. ([[COMIC]]: ''[[The Girl Who Loved Doctor Who (comic story)|The Girl Who Loved Doctor Who]]'')

=== Post-regeneration ===
[[File:Twelfth Doctor Post-Regeneration.jpg|thumb|left|A befuddled Twelfth Doctor stares at Clara Oswald immediately after his thirteenth regeneration. ([[TV]]: ''[[The Time of the Doctor (TV story)|The Time of the Doctor]]'')]]
After fighting in the Siege of Trenzalore for 900 years, ([[PROSE]]: ''[[Tales of Trenzalore: The Eleventh Doctor's Last Stand (anthology)|Tales of Trenzalore: The Eleventh Doctor's Last Stand]]'') the [[Eleventh Doctor]], out of regenerations, facing extermination by the [[Dalek]]s, and already dying of old age, was ready to accept that he had reached the end of his life. Unable to accept that his death was unavoidable, [[Clara Oswald]] appealed to the [[Time Lord]]s to intervene, and they responded by granting the Doctor a new regeneration cycle. After using the energy from the explosive reset that followed to destroy the Dalek forces besieging Trenzalore, the Doctor returned to his TARDIS to complete his thirteenth regeneration.
 
Suddenly changing in a flash before Clara's eyes, the new Doctor voiced his surprise at having new kidneys. The TARDIS then began shaking violently, and the Doctor implied to have forgotten how to pilot his ship, much to a shocked Clara's dismay. ([[TV]]: ''[[The Time of the Doctor (TV story)|The Time of the Doctor]]'') Crashing in pre-historic Earth, the TARDIS was chased and subsequently swallowed by a female [[tyrannosaur]]; when the Doctor brought the TARDIS to [[1890s]] [[London]], the dinosaur was accidentally brought along with it.
 
After the TARDIS was spat out, the Doctor, in a severe bout of post-regenerative trauma, acted very wild and irrationally. He peeked out of the TARDIS door, shushed [[Strax]], slammed the door shut momentarily, and then finally crept out of the TARDIS, trying to identify him as one of the Seven Dwarves. Unable to remember names or faces clearly, he sputtered at the sight of the [[Paternoster Gang]], before being joined by a frazzled and annoyed Clara, trying to keep some degree of control on his livid and maddened state.
 
Though put to bed to stabilise, the Doctor soon awoke and, grabbing a piece of [[chalk]], doodled strange equations all over the bedroom. Hearing the dinosaur in pain, the Doctor climbed out onto the rooftop and left on horseback when he saw the T-Rex was being burned to ashes. Deciding to investigate, but still suffering a degree of post-regenerative stress, the Doctor wandered the streets of London. Talking to a passing tramp, the Doctor examined his new facial features, noticing that he had [[Lobus Caecilius|seen it before]]. He took particular note of his new eyebrows, as well as his new Scottish accent, before trading in his previous incarnation's favourite watch for the tramp's coat. ([[TV]]: ''[[Deep Breath (TV story)|Deep Breath]]'')
 
[[File:Twelve Clara Half-Face Man.jpg|thumb|right|The Doctor and Clara examine the dormant Half-Face Man.  ([[TV]]: ''[[Deep Breath]]'')]]
Seeing an ad in a newspaper placed by {{Gomez}}, ([[TV]]: ''[[Death in Heaven (TV story)|Death in Heaven]]'') which seemed to be a message from Clara, the Doctor infiltrated a suspicious restaurant, where he and Clara learned that time travelling [[Clockwork Droid]]s, under the leadership of the [[Half-Face Man]], had been harvesting [[human]]s to repair themselves and reach the Promised Land. Trying to speak on peaceful terms, the Doctor snapped the Control Node out of his illusion of the Promised Land by revealing the true state of his existence. Conflicted and unsure, the Half-Face Man fell out of his [[escape pod]], either jumping or having been pushed by the Doctor.
 
[[File:Clara_hugging_Doctor.jpg|thumb|left|The Doctor states that he's not a "hugging person". ( [[COMIC]]: ''[[The Bin Dilemma (comic story)|The Bin Dilemma]]'')]]
The Doctor briefly left Clara behind to redecorate the TARDIS console room and settle on a new outfit. Returning for Clara, the Doctor spoke of the suspicious way Clara had met him in his previous incarnation, only for Clara to likewise voice her uncertainty of the Doctor's identity and asked to be returned home. Attempting to return Clara home, the Doctor ended up in [[Glasgow]] by mistake. However, Clara decided to go out for coffee with the new Doctor after the Eleventh Doctor called her and encouraged her to help the Doctor through his regeneration; the new Doctor, however, seemed uncomfortable with the hug Clara gave him. ([[TV]]: ''[[Deep Breath (TV story)|Deep Breath]]'')
 
=== Early experiences ===
Wanting to investigate a series of murders, the Doctor left Clara behind in Glasgow to get her some coffee from the [[Intergalactic Coffee Roasting Station]]. There, the Doctor made conversation with a mutant called [[78351 (Lights Out)|78351]] in the queue, and then realised that, in a previous incarnation, he had saved 78351 and others like him from a laboratory on [[Collabria]]. Before either could go into further detail, the coffee ran out and a female customer was killed during a blackout.
 
Deciding to take 78351 on as a companion, the Doctor examined the dead body and determined that all the caffeine in her system had been drained. Briefly accused of being the killer before suspicion fell elsewhere, the Doctor found two bite marks on the deceased, and then a [[Blowfish]] was also murdered. Using his sonic screwdriver, the Doctor found that 78351's adrenaline levels had increased, and, fearful that he would be the next victim, claimed that he was tired of the lights going out and took 78351 to the master control centre to draw out the killer, telling 78351 that they were going to fix the lights.
 
Finding the technicians murdered, and that they had been killed fourteen hours before the first victim, the lights suddenly went out again and, when both of them emerged unharmed, the Doctor realised that 78351 was the killer, as his adrenaline levels had decreased. Wanting to take him off the station, the Doctor had 78351 take him to his ship. Managing to outmaneuver the security drones, the Doctor and 78351 fled the ICRS, and the Doctor informed 78351 of his discoveries.
 
Turning out the ship's lights to see 78351's true form, the Doctor likened 78351's transformation to puberty, and told him he had to decide if he wanted to control his adult body. When he also told him that he might not have the energy to stabilise himself, 78351 set his ship to collide with a nearby sun to get the energy burst. Promising to buy 78351's friend a coffee from him, the Doctor left the ship in an escape pod, and returned to the ICRS. ([[PROSE]]: ''[[Lights Out (short story)|Lights Out]]'')
 
Intending to return to Clara with some coffee, the Doctor saved a [[Combined Galactic Resistance]] fighter pilot named [[Journey Blue]] from a [[Dalek Saucer]] attack, though left [[Kai Blue|her brother]] behind in the explosion. After prompting her into asking nicely, the Doctor returned Journey to her command ship, the ''[[Aristotle (spaceship)|Aristotle]]'', where Colonel [[Morgan Blue]] introduced him to a [[Dalek]] that had developed a fault and turned good.
 
[[File:Twelve listening to Rusty.jpg|thumb|left|The Doctor, shrunken down inside a [[Dalek]], learns why it became "good". ([[TV]]: ''[[Into the Dalek (TV story)|Into the Dalek]]'')]]
Returning for Clara, three weeks later from her perspective, the Doctor asked her if she thought he was a good man, a question that Clara found herself unable to answer, and returned to base to help the Dalek. Joined by Journey and two other soldiers named [[Gretchen Carlisle]] and [[Ross (Into the Dalek)|Ross]], the Doctor and Clara used a [[Molecular nanoscaler]] to miniaturise themselves and enter the Dalek — whom the Doctor nicknamed "[[Rusty]]". After losing Ross to the [[Dalek antibody|Dalek's antibodies]], the Doctor discovered a radiation leak from within the Dalek and learned that Rusty had turned good after seeing a star being born. Following the radiation, the Doctor discovered damage to Rusty's power source was slowly killing him, and repaired the damage with his [[sonic screwdriver]].
 
However, fixing Rusty's power core resulted in the malfunction that turned Rusty good to be reversed, with Rusty's destructive nature returning, and causing Rusty to go on a killing spree, as well as send a distress beacon to summon the Daleks to the rebels' base. After getting slapped and lectured by Clara for his apathy, the Doctor realised he could turn Rusty good again by reawakening his memory of the star being born.
 
Instructing Clara to find a way to restore Rusty's memories of the star, the Doctor made his way to the [[Kaled mutant]] within Rusty to mind linked with him, causing Rusty to see the Doctor's hatred of the Daleks and destroy the Daleks that had responded to his distress beacon. Leaving to continue his crusade against the Daleks, Rusty commented that Doctor would have made a good Dalek before both of them left. After declining Journey's request to travel with him and Clara, the Doctor returned Clara home, both still unsure if the Doctor was a good man, but with Clara convinced he was at least trying to be one. ([[TV]]: ''[[Into the Dalek (TV story)|Into the Dalek]]'')
 
=== New adventures with Clara ===
Spending some more time on his own, the Doctor became alerted to a creature that disguised itself as a motorway to consume planets into other dimensions. Summoning Clara to assist him, the Doctor was surprised when the creature disappeared, unaware that Clara had tricked the creature into consuming itself. ([[COMIC]]: ''[[Road Rage (Twelfth Doctor comic story)|Road Rage]]'')
 
The Doctor was given some [[chip]]s by Clara, and then rambled about how great they tasted. ([[COMIC]]: ''[[Untitled (12D comic story)|Untitled]]'') Attempting to get a reservation at a restaurant on [[Calbaron III]], the Doctor and Clara found there was a three-year lack of tables. They booked and went three years to the future, only to learn the restaurant was closed to celebrate the third anniversary of the overthrowing of a tyrannical emperor. They finally made their booking six years prior for three years later. When the Doctor found that the tyrannical emperor had scratched his TARDIS, he decided to overthrow him, resulting in the anniversary. ([[COMIC]]: ''[[Planet of the Diners (comic story)|Planet of the Diners]]'')
 
The Doctor repaired a scratch on the TARDIS, but found that this caused time within the TARDIS to temporarily run backwards, much to Clara's annoyance when she tried to converse with him. ([[COMIC]]: ''[[The Inversion of Time (comic story)|The Inversion of Time]]'')
 
When the TARDIS was swarmed with [[Adipose]], the Doctor claimed he was "not an Adipose person." He then had Clara take out the rubbish, as he claimed he wasn't a "taking-the-bin-out" person, with Clara declaring his attitude had to stop. ([[COMIC]]: ''[[The Bin Dilemma (comic story)|The Bin Dilemma]]'')
 
Deciding to return to Victorian London, the Doctor and Clara reunited with the [[Paternoster Gang]] to investigate a carnival at the Frost Fairs, where some performers had gained powers, in connection with a death that had occurred. They discovered these events were linked to weapon-creator [[Orestes Milton]], who was hiding from the [[Shadow Proclamation]]. The Doctor stopped Milton's anger-inducing machine, but was unable to prevent his escape. However, Affinity, a shape-shifter created by Milton, tricked the rogue into thinking the Shadow Proclamation wanted his help; the real organization destroyed Milton's ship when it attempted to leave Earth. The humans altered by Milton retained their powers, deciding to resume their work at the fair. ([[PROSE]]: ''[[Silhouette (novel)|Silhouette]]'')
 
Deciding to give Clara the choice of their next destination, the Doctor took her to [[Sherwood Forest]] to meet [[Robin Hood]], though he was sceptical of Robin's actual existence. He was proven wrong when Robin shot his TARDIS with an arrow seconds after they arrived; however, he refused to believe Robin and his [[Merry Men]] were real upon visiting their camp.
 
After participating in an [[archery]] contest for a golden arrow, the Doctor got himself, Clara and Robin captured by the [[Sheriff of Nottingham]], who had allied with alien robots disguised as [[Knight (Robot of Sherwood)|his knights]]. Escaping, the Doctor and Robin found out the robots were trying to reach [[Nethersphere|the Promised Land]], but lacked sufficient [[gold]] to repair their engine. Believing Robin was also a robot, the Doctor was re-captured by the Sheriff as Robin took Clara and escaped through a window. Leading a revolution in the Sheriff's dungeon, the Doctor was informed by the Sheriff that Robin Hood was not a robot, just as Robin came to his rescue and defeated the Sheriff. Assisting Robin with Clara's help, the Doctor helped launch the golden arrow into the ship to allow it to escape velocity and explode harmlessly in space.
 
[[File:12 and Robin.jpg|thumb|right|The Doctor finally acknowledges Robin Hood as a real person. ([[TV]]: ''[[Robot of Sherwood (TV story)|Robot of Sherwood]]'')]]
Robin, having learned about the Doctor's story from Clara, noted that the two of them were not so different from each other: both of them were people born into status and privilege, giving up both to live the life of an adventurer in order to fight injustice. As he departed, the Doctor left [[Maid Marian]], whom he had met in the Sheriff's dungeon, behind to be reunited with Robin. ([[TV]]: ''[[Robot of Sherwood (TV story)|Robot of Sherwood]]'')
 
The Doctor and Clara used a [[goo bomb]] to foil the [[Sibro]]'s attempt to weaponise a Conlanian clock tower, ([[COMIC]]: ''[[Chime Time (comic story)|Chime Time]]'') orchestrated a ceasefire in a war between anthropomorphic [[cat]]s and [[dog]]s by allying them against an army of alien fleas that planned to attack every planet in the universe, ([[COMIC]]: ''[[Once Bitten (comic story)|Once Bitten]]'') and helped the [[World Brain]] find a new way of life after crash landing on its factory planet. ([[COMIC]]: ''[[Crash Landing (comic story)|Crash Landing]]'')
 
While sightseeing on the [[HomeWorld (planet)|HomeWorld]], the Doctor saved a hospital from a missile, but was framed as the ringleader of various crimes by [[the Judge]] and locked up in the colony's asteroid [[The Prison|prison]] until he exposed its darkest security measure. ([[PROSE]]: ''[[The Blood Cell (novel)|The Blood Cell]]'')
 
The Doctor and Clara rescued the spaceship ''[[Genetrix]]'' from [[Wispy|Whispies]] on [[Venus]] by using the ship's sifters to suck them up. ([[PROSE]]: ''[[Sunset Over Venus (short story)|Sunset Over Venus]]'')
 
On [[Hoopoe]], the Doctor acted as Clara's [[lawyer]] when she was arrested for walking on the ground by the [[Court of Birds]]. His attempt to convince them she and him weren't cats backfired when the owls accused them of being mice, but the Doctor had foreseen this and had recruited the native cats to attack the owls with makeshift wings, but ensured that the wings were too difficult to use properly, rendering them useless in the cats' pursuit of the owls. As he left with Clara in the TARDIS, the Doctor rewarded the cats with a box of canned tuna.  ([[COMIC]]: ''[[The Court of Birds (comic story)|The Court of Birds]]'')
 
[[File:Listen (TV Story).jpg|thumb|left|The Doctor meditating on top of the TARDIS. ([[TV]]: ''[[Listen (TV story)|Listen]]'')]]
During one of Clara's breaks from the TARDIS, the Doctor became obsessed with the idea that a creature designed to hide was following him around and that everyone was similarly being followed. Visiting Clara for help in finding the hiders, by using the TARDIS [[telepathic circuit]]s to pilot into her past. However, Clara got distracted by a phone call from her date, [[Danny Pink]], and piloted them into his past instead, back when Danny was a child called Rupert and living in a care home. Finding a [[Figure (Listen)|figure]] under Rupert's bed sheet, the Doctor had Clara and Rupert turn their backs to allow the being to walk out the room unobserved, leaving them unsure if it really was a creature or just another child playing a trick on Rupert.
 
Returning Clara to her date, the Doctor continued to follow his theory by trying to use a trace of Clara left in the telepathic circuits, ending up at the [[end of the universe]] where a time traveller named Colonel [[Orson Pink]], Danny's descendant, had been trapped for six months. Intrigued by how following Clara's timeline led him to Orson, the Doctor returned for Clara and had them wait at the end of the universe for the night, believing it to be the perfect time to find out if the hiders were real. Finding a chance to confront the creature outside the ship, the Doctor sent Clara into the TARDIS and seemed to get a look at what he's been chasing before the atmospheric shell broke and Orson had to rescue him. As the Doctor was knocked out, and the TARDIS seemed to be under attack, Clara used the telepathic circuits to fly the TARDIS away.
 
Waking up to find Clara gone, the Doctor called out to her and inadvertently alerted [[First Doctor|his younger self]] to Clara's presence. Before he could investigate, Clara re-entered the TARDIS and made him promise to leave and not find out where they had landed. Afterwards, the Doctor returned Orson and Clara to their own times and, satisfied by what he had learned, underlined the word "Listen" that the creature had written on his chalkboard. ([[TV]]: ''[[Listen (TV story)|Listen]]'')
 
The Doctor planned to rendezvous with Clara at Coal Hill School, but instead arrived at a replica of the school on an [[Planet (The Monsters of Coal Hill School)|unnamed planet]], where Clara and [[Jeff Delobel]], a French teacher, had been abducted by [[Creature (The Monsters of Coal Hill School)|primitive aliens]] planning to infiltrate Earth via Coal Hill School. In order thwart the invasion, the Doctor told the aliens a tale of Earth's Guardian, informing them that he was the guardian, scaring the aliens off. ([[COMIC]]: ''[[The Monsters of Coal Hill School (comic story)|The Monsters of Coal Hill School]]'')
 
Resuming their travels, the Doctor and Clara helped stranded [[Seevith]] launch their ship, ([[COMIC]]: ''[[More Than Meets the Eye (comic story)|More Than Meets the Eye]]'') and helped Professor [[Faster]] end the [[17th century]] witch trials. ([[COMIC]]: ''[[Witch Work (comic story)|Witch Work]]'')
 
Returning to pick up Clara, and persuade her to away from a date with Danny Pink in favour of other travel destinations, the Doctor received a call from Madame [[Karabraxos]], who requested he free [[The Teller (Time Heist)|the Teller]] and its mate from the [[Bank of Karabraxos]], as he had done on the day she met him. Realising the ramifications of this request, the Doctor built up the identity of "the Architect", using this identity to stage a bank heist for him to commit, with the assistance of Clara, an [[augmented human]] named [[Psi]], and a shape shifting [[mutant human]] named [[Saibra]].
 
Using [[memory worm]]s to erase the plan from their minds and prevent the Teller from alerting the young Karabraxos, the Doctor and Clara found themselves already in the Bank with their accomplices, their last memory being the [[TARDIS phone]] ringing.
 
Receiving instructions from the Architect on their location, objective, and the Bank's security system, the team infiltrated the Bank. Entering a safety deposit box, "Team Not Dead" - the Doctor's name for the assembled team - set of a [[dimensional shift bomb]] into a service corridor, where the team found a briefcase containing six teleporters disguised as [[atomic shredder]]s.
 
Seemingly losing Saibra and Psi to the shredders when the Teller locked onto them, the Doctor figured out that time travel was involved with the heist plan when a perfectly-timed [[solar storm]] unlocked the Bank's vault. Retrieving what the Architect had promised Psi and Saibra as payment, the Doctor and Clara were caught by the Teller and delivered to the bank manager, Ms. [[Delphox]]. After Delphox left them to be executed, the Doctor and Clara were saved by Psi and Saibra, who revealed the true nature of the "shredders".
 
[[File:Emboldened_Twelve.jpg|thumb|right|The Doctor [[deduce]]s himself to be the Architect. ([[TV]]: ''[[Time Heist (TV story)|Time Heist]]'')]]
Venturing into the Bank's private vault to find his and Clara's reward, the Doctor instead found Director Karabraxos, and discovered that Delphox, as well as a majority of the bank's staff, was an exact clone of Karabraxos. Seeing Karabraxos' hatred of her own clones caused the Doctor to have an epiphany on the identity of the Architect, and he gave his phone number to Karabraxos as she fled from the solar storm about to hit the Bank. Subjecting himself to the Teller's powers, the Doctor regained his lost memories and realised the true objective of the bank heist. Freeing the Teller and its mate to a place to live in solitude, the Doctor then parted ways with Psi and Saibra, giving them their rewards, and returned Clara home for her date. ([[TV]]: ''[[Time Heist (TV story)|Time Heist]]'')
 
The Doctor and Clara were later pitted against the [[Wyrrester]]s during their second attempt to invade Earth, with the Doctor also travelling back to ensure the failure of their first attempt and Clara briefly switching bodies with a Wyrrester before they were defeated. ([[PROSE]]: ''[[The Crawling Terror (novel)|The Crawling Terror]]'')
 
The Doctor and Clara were left to the mercy of [[sand piranha]]s while chained to posts on a [[Planet (The Caretaker)|desert planet]], ([[TV]]: ''[[The Caretaker (TV story)|The Caretaker]]'') had a dinner date in [[1937]] [[Berlin]], ([[TV]]: ''[[Kill the Moon]]'') and rendezvoused with [[Fish Person|fish people]]. ([[TV]]: ''[[The Caretaker (TV story)|The Caretaker]]'')
 
At some point, the TARDIS had been lost in [[22nd century]] London and kept a boy called [[Simon (When the Wolves Came)|Simon]] safe when the city had been taken over by [[Wolf|wolves]]. At a time when Simon, the Doctor and Clara all needed help, Simon triggered the TARDIS' telepathic circuits and the TARDIS materialised around the Doctor and Clara just as they were "about to be turned into toast by an [[Aaaraanandal slime beast]]". They took Simon out of the danger zone to bring him to his parents in [[Bedfordshire]], before leaving in the TARDIS. ([[PROSE]]: ''[[When the Wolves Came (short story)|When the Wolves Came]]'')
 
The Doctor and Clara outran soldiers to escape in the TARDIS, ([[TV]]: ''[[The Caretaker (TV story)|The Caretaker]]'') and saved a small village from a [[Cephla]] at [[Christmas]]. ([[COMIC]]: ''[[Gift Snatched! (comic story)|Gift Snatched!]]'')
 
Planning to visit [[Eden 2]], the Doctor was joined by a reluctant Clara, after she phoned him to drop her off at work after she overslept. When the duo arrived, they found the under assimilation by the [[Vladlack]], but it turned out that the planet was a trap, to lure in and arrest invaders of planets. Fearing that innocents could be inappropriately punished, the Doctor set up a warning beacon around the planet, then dropped Clara off at Coal Hill School. ([[COMIC]]: ''[[Freeze (comic story)|Freeze]]'')
 
=== Meeting Danny and Courtney ===
Discovering a [[Skovox Blitzer]] near [[Coal Hill School]], the Doctor went in "deep cover" as the school's temporary caretaker to dispatch of the killer robot, much to Clara's dismay.
 
[[File:Doctor giving commands to the Skovox.jpg|thumb|left|An undercover Doctor dissuades a Skovox Blitzer from using its [[self-destruct]]. ([[TV]]: ''[[The Caretaker (TV story)|The Caretaker]]'')]]
Initially planning on using [[chronodyne generator]]s to send the Blitzer into the future, the Doctor's plan was accidentally foiled by [[Danny Pink]]; Danny had seen the Doctor act suspiciously and believed the devices were of malicious intent, deactivating some. As a result, the Blitzer was sent a short time into the future, rather than centuries. After Clara introduced him as her boyfriend, the Doctor took a dislike to Danny as he was a former soldier and feared he wasn't good enough for Clara. He changed his plan to using a communication device to make the Blitzer think the Doctor was its superior.
 
Rather a few days, the Blitzer returned during the next evening; to the Doctor's surprise, Danny used his military training to help keep the Blitzer occupied, allowing him to repair the malfunctioning device. After successfully commanding the Blitzer to deactivate with Danny's help, the Doctor took into space and ejected it from the TARDIS, taking Clara's troublesome pupil [[Courtney Woods]] with him after she discovered his identity, deciding that there was no harm in having Courtney tag along as a travelling companion, ([[TV]]: ''[[The Caretaker (TV story)|The Caretaker]]'') but didn't see anything special in her. ([[TV]]: ''[[Kill the Moon (TV story)|Kill the Moon]]'')
 
=== Further adventures with Clara ===
[[File:TITAN 12th 1 Run.jpg|thumb|Clara and the Doctor trying to escape as Rann-Korr reveals himself. ([[COMIC]]: ''[[Terrorformer (comic story)|Terrorformer]]'')]]
The Doctor brought Clara to the planet [[Isen VI]] to check on a faint warning signal of Gallifreian origin. They found the planet being [[terraform]]ed by [[Kano Dollar]] and his company [[Dollar Intergalactic]], which woke up a [[Hyperion (species)|Hyperion]] named [[Rann-Korr]], who was hiding in hibernation since the alliance of races led by [[Rassilon]] defeated [[Hyperios]]. Despite not having a fleet of battle TARDISes at his disposal, the Doctor managed to freeze Rann-Korr by reversing the terraforming process while using himself as a bait. ([[COMIC]]: ''[[Terrorformer (comic story)|Terrorformer]]'')
 
Discovering that a group of aliens were going to turn a planet of anthropomorphic pink [[Hippopotamus|hippopotami]] into stone, the Doctor intercepted the aliens at the early stages of their invasion and led them to ancient [[Egypt]], where they petrified a large cat-like alien, creating the [[Sphinx]] and getting crushed in the process. He and Clara then returned to the planet of the anthropomorphic pink hippopotamuses to reverse the petrified effect. ([[COMIC]]: ''[[Petrified (DWA comic story)|Petrified]]'')
 
While Clara was having her [[Mona Lisa|portrait painted]] by [[Leonardo da Vinci]] in [[1505]], the Doctor received a summon to [[2315]] [[India]] from an old acquaintance of his, [[Tiger Maratha]], who foresaw a timeless evil. The Doctor and Clara arrived in 2315 to find he had been killed and drained of life, and along with Tiger's daughter [[Priyanka Maratha|Priyanka]] were confronted by police who attempted to arrest the Doctor. Escaping capture, Priyanka told the Doctor and Clara that Tiger had worked for a group known as the [[Family Scindas]]. The Doctor, Clara and Priyanka travelled to the Scindas' ancestral home to find information, however the Doctor stumbled through a dimensional door into [[1825]] [[India]], where he was attacked by a demon but rescued by renegade Amazon [[Rani Jhulka]]. The Doctor and Rani found a [[necro-cloud]] harvesting the spirits of the dead, and then attacked by more of the demons. Before they could be overpowered by the demons, the TARDIS arrived, Priyanka having unintentionally activated the telepathic circuits. She told the Doctor Clara had been taken by the demons.
 
[[File:Twelve battles Kali.jpg |thumb|left|The Doctor battles with Kali. ([[COMIC]]: ''[[The Swords of Kali (comic story)|The Swords of Kali]]'')]]
Back in 2315, the Doctor, Priyanka and Rani found a final recorded message from Tiger made before his death, in which he explained he had collected three of the four mythic swords of the [[god]]dess [[Kali]] for the Family Scindas and had a premonition of evil over the swords. The Doctor was then summoned to see [[Chandra Scindas]], the patriarch of the Scindas family. The Doctor [[deduce]]d that they were beings known as the [[Kaliratha]], putting themselves throughout time and space and Hindu mythology. Chandra revealed he had Clara hostage, ready to be burned by the Exodus rocket, forcing the Doctor to agree to find the fourth sword of Kali for them. The Doctor, Priyanka and Rani collected the fourth sword and returned to Chandra, who revealed he had used Clara as a host for the resurrection of Kali. Priyanka took control of the rocket while the Doctor battled with Kali. The Doctor revealed he hid his sonic screwdriver in the fourth sword, so that Kali unwittingly freed the evil spirits from her and released Clara's body, while Rani killed Chandra. The Doctor, Clara, Rani and Priyanka then attended a festival in [[Mumbai]]. ([[COMIC]]: ''[[The Swords of Kali (comic story)|The Swords of Kali]]'')
 
While attempting to hang [[flower]]s on the exterior of the TARDIS, the Doctor was spooked by a future Clara and fell out of the TARDIS into the orbit of an [[asteroid]]. When Clara's attempt to avert the crisis ended up causing it, the TARDIS was able to save the Doctor by creating a time field around him. ([[PROSE]]: ''[[A Long Way Down (short story)|A Long Way Down]]'')
 
The Doctor and Clara turned Captain [[Ratlett]]'s crew against him and showed them a better life,  ([[COMIC]]: ''[[The Wheelers (comic story)|The Wheelers]]'') were almost consumed by robotic bananas for stealing food from the [[moon]] [[Luna Schlosser]], ([[COMIC]]: ''[[Five a Day (comic story)|Five a Day]]'') and saved the Cloud City of [[Mirmi 24]] from being eaten by an alien snake.

[[File:12th_Doctor_Comics_The_Fractures_3d_Glasses.jpg|thumb|The Doctor looks for [[Void stuff]] with his [[glasses|3D glasses]]. ([[COMIC]]: ''[[The Fractures (comic story)|The Fractures]]'')]]
After stopping a hostile invasion in the future, the Doctor travelled to [[Tower of London|UNIT HQ]], where he had just been in time to shut down a [[the Void|Void]] portal. The Doctor came into conflict with the [[Fracture]]s, natives of [[the Void]] that possessed humans, who believed they had to drag anyone mark with [[Void stuff]] into the Void to protect reality from unravelling. The chaos was started by a [[UNIT]] scientist from an [[alternate Earth]], [[Paul Foster]], who wished to be with a version of his family. Recruiting UNIT, [[Kate Stewart]] and the Fosters' help, the Doctor and Clara opened the Void, drawing the Fractures back inside and freeing their victims. At Clara's insistence, the Doctor allowed the alternate Paul to join his family in their universe, knowing the Fractures were entirely out for him now. ([[COMIC]]: ''[[The Fractures (comic story)|The Fractures]]'')
 
=== Preventing a bad future ===
After visiting an uninhabited world that lacked development in any way, Clara asked the Doctor about [[Marinus]], but he did not remember the planet. That night, as he slept, the Doctor worked out that Clara was up to something, and woke up to find Clara missing and the TARDIS in [[1923]] [[Paris]].
 
Looking for Clara in a café, the Doctor ran into his two previous incarnations, who were also heading to meet their respective companions. When the three Doctors barged into the café to confront each other, Clara, [[Alice Obiefune]] and [[Gabby Gonzalez]] explained that moments before they had entered a version of Gabby from the future, who had warned them of the plan devised by a future "alternate" version of the Twelfth Doctor. The future Twelfth Doctor had used a continuity bomb to make his timeline concrete, and had then returned the Doctors to their own timelines, erasing their memories of the events. The alternate Doctor planned to rise the [[Voord]] on [[Marinus]] to be a new race of [[Time Lord]]s and to conquer the universe. Alice had been killed as she fled through his domain, and Gabby had been sent back in time by a [[Weeping Angel]] which had grown from the Eleventh Doctor's pack of comics. Realising that the picture of the three meeting still existed, they decided that going to Marinus was still part of the new timeline, and the three left [[Paris]].
 
On Marinus, the Doctors posed for the picture and purposefully fell into the [[continuity bomb]], where they chose the timeline where the Eleventh Doctor had stayed in the reality where all time occurred at once, as Marinus still existed in that timeline. There, they discovered the crashed [[Dalek]] ship which was where the [[Voord]] had stolen the technology to create their pocket universe. The Twelfth Doctor convinced the Voord that he was his [[Twelfth Doctor#Multi-Doctor event|alternate self]], and joined with their hive mind. There, as he distracted all of the Voord subjects with thoughts of [[Horse|ponies]], he encountered his alternate self, and the two fought within the mindscape.
 
[[File:TwelveBattlesSelfFD.jpg|thumb|left|The Doctors battles his alternate self. ([[COMIC]]: ''[[Four Doctors (comic story)|Four Doctors]]'')]]
Realising that his alternate self was too powerful to take on alone, the Doctor brought his other selves and their companions into the hive mind. They distracted the alternate Doctor as the Eleventh and Tenth Doctors broke down the Voord city's shields and connected the reprogrammed Dalek weapon to the city's dimensional shielding. The Doctors gave their alternate self, now trapped within the hive mind with them, the option to either let his city fry or use the technology in the city to revert the Voord to their pre-Time War state. Convinced by Clara, the alternate Doctor agreed to the latter, even if it meant that he and the timeline he created would cease to exist.
 
Seeing the new Marinus, populated by large cities and primitive Voord, the six returned to [[Paris]], and considered eating at the café, until they saw the [[Ninth Doctor]] and [[Rose Tyler]] seated inside, with the Twelfth Doctor saying that the Ninth Doctor had been left out of the plot due to there being no timeline that even the continuity bomb could find where he was anything but "fantastic."
 
As the groups departed, the Twelfth Doctor questioned his previous selves decision not to wipe their companions' memories, and noted to Clara that, while he would also never do such a thing to her, she and himself would slowly forget the event as well, as they had both learned about their own futures. As their memories began fading, Clara asked if the Doctor ever wanted to become his previous selves again, much like how she sometimes wished to be a teenager again. Though he avoided answering the question, the Doctor noted that his two predecessors "lived like they had limited time," and that staying in the past was not for them, and that they had to move forward into the future. ([[COMIC]]: ''[[Four Doctors (comic story)|Four Doctors]]'')
 
=== Fallout with Clara ===
At Clara's urging, the Doctor took her and Courtney to the Moon in [[2049]], so that Courtney could be the first girl on the Moon to bolster her confidence. Landing instead in a recycled space shuttle heading for the moon, the Doctor was informed by Captain [[Lundvik]] that the moon had inexplicably gained mass, and that she and her crew were going to use nuclear bombs to dispose of the additional mass.
 
Investigating a disused mining base from a previous mission, the Doctor, his companions and the astronauts found corpses preserved in webs and research that suggested that the moon was disintegrating. Soon after, the group was attacked by a spider creature, which Courtney killed with washing up equipment, but not before Lundvik's crew were killed.
 
Taking a scared Courtney back to the TARDIS, the Doctor voiced his uncertainty of the Moon's fate to Clara, calling it a "grey area" in time. Exploring the moon's surface for the reason behind the deterioration, the Doctor, Clara and Lundvik discovered a horde of spider germs beneath the Moon's surface, as well as amniotic fluid, prompting the Doctor to investigate beneath the Moon for answers.
 
[[File:Doctor Refusing to Interfere.jpg|thumb|The Doctor refuses to help humanity make a critical decision when time is in flux.  ([[TV]]: ''[[Kill the Moon (TV story)|Kill the Moon]]'')]]
Scanning the Moon's core, the Doctor discovered that the Moon was, in fact, an egg for an ancient creature that was hatching. Reuniting with Clara and Lundvik after the shuttle and the TARDIS fell into a canyon, the Doctor informed them of his discovery after establishing contact with Courtney's phone. While Clara and Lundvik argued about killing the creature for the sake of the Earth, the Doctor had Courtney bring the TARDIS to him via DVD, deciding that it was not his place to decide the Moon's future, and left in his TARDIS for Clara, Lundvik and Courtney to decide on behalf of humankind.
 
After Clara chose to spare the creature, despite humanity voting for its death, the Doctor returned for the three women, taking them to a beach on Earth to see the creature hatch and the Moon harmlessly disintegrate in Earth's atmosphere. Confirming that the sight of the moon hatching kick started the humans pioneering into space, and seeing the creature hatch a new egg with same mass as the old Moon, the Doctor returned Courtney and Clara to Coal Hill School.
 
[[File:Stunned Twelve.jpg|thumb|left|The Doctor looks on after Clara storms out of the TARDIS. ([[TV]]: ''[[Kill the Moon (TV story)|Kill the Moon]]'')]]
However, Clara, angered by the position the Doctor had put her in, asked the Doctor if he had known the egg was harmless, which the Doctor confirmed as true. Tired of the Doctor's apathy, Clara argued with the Doctor about how he had almost caused her to kill an unborn creature. He defended that he was helping the human race by not playing a part in this choice. However, Clara had been deeply hurt by the Doctor's constantly patronising attitude toward humanity, and now that he had demonstrated it with her, Clara felt reduced to the likes of an idiot in the Doctor's eyes. With tears rolling down her face, she told him to leave and not return for her. The Doctor was left stunned by her reaction and immediately took off. ([[TV]]: ''[[Kill the Moon (TV story)|Kill the Moon]]'')
 
=== Time alone ===
{{section stub|Info from ''[[Super Gran (comic story)|Super Gran]]'' needs to be added}}
Spending some time away from Clara, the Doctor joined a crew of six travellers, including a young [[Geoffrey Chaucer]], on a journey to the church at Santiago de Compostela to avoid the plague. At the church, one of the travellers gave birth, then the group were attacked by life-feeding aliens disguised as wooden skeletons. However, the aliens recoiled in horror upon seeing the new baby. The Doctor realised the church was actually the aliens' disguised spaceship, and he and the crew escaped as the ship took off and away. The Doctor explained to Chaucer that the baby, representing new life, was enough to frighten away the death-conquering aliens. ([[PROSE]]: ''[[The Mercy Seats (short story)|The Mercy Seats]]'')
 
Responding to a distress call from Dalek prisoner aboard a [[Cyber Ship]], the Doctor discovered that the Daleks, [[Cyberman (Mondas)|Cybermen]] and [[Sontaran]]s were searching for the [[Orb of Fates]] to gain control of a powerful Time Lord weapon called the [[Starbane]]. The Doctor joined forces with the Dalek prisoner, who had been altered by the Cybermen and "seen the light" and nicknamed it "[[Lumpy]]". Following the Orbs' [[Artron energy]] to the [[Cyber-tomb]]s of [[Telos]], the Doctor restored a minimum of Lumpy's power, not trusting the Dalek to allow full use of its power, and sent him to retrieve the second Orb while he studied the first in the TARDIS.
 
As Lumpy descended into the depths of Telos, the Doctor discovered that the Orbs were powered by temporal energy; The only way to destroy them was to create a temporal implosion. Leaving Telos for [[Sontar]], the Doctor and Lumpy were trapped in a [[stasis field]] by [[Major]] [[Skar]], but the Doctor was able to open the field and allow Lumpy to escape undetected while he stayed behind as a diversion. After Lumpy acquired the last Orb and deactivated the stasis field, the Doctor escaped with Lumpy, deciding it best to stay clear of Sontar for a while. They next travelled to the Starbane. However, [[Lumpy]] pointed out that it was already occupied by [[Dalek]]s. When learning Lumpy was not turned to good, Doctor had found a way to access Lumpy's controls remotely and used this ability to destroy the ''Starbane''. ([[GAME]]: ''[[The Doctor and the Dalek]]'')
 
On Christmas Eve 2014, the Doctor teamed up with [[Ceri (Behind You)|Ceri]], an understudy, to fraught an [[Addos]] attempt to recreate a [[Mummers play]] by genetically altering actors from the [[Palace Theatre]]. ([[PROSE]]: ''[[Behind You (short story)|Behind You]]'')
 
The Doctor learnt that an invasion fleet of [[Megrati]] were planning to attack the planet of [[Lemaria]], a plan he had previously stopped in his [[First Doctor|first incarnation]]. The Doctor sent them an invitation to give them some time to talk. While waiting for them to arrive, the Doctor took part in a Freedom Day celebratory play about the original defeat of the Lemaria, playing himself. The Doctor realised his [[Fifth Doctor|fifth incarnation]], [[Adric]], [[Nyssa]] and [[Tegan Jovanka]] were in the audience before the real Megrati arrived. As his past self and companions watched, the Doctor convinced the Megrati to leave the planet by threatening to destroy their ships. ([[PROSE]]: ''[[The Constant Doctor (short story)|The Constant Doctor]]'')
 
A force brought the TARDIS off course, where it was forced to land on a place the Doctor nicknamed "[[Planet Wet]]". When the Doctor exited the TARDIS, the hillock swallowed the TARDIS whole, and the Doctor was forced to find his way to a building, where he found the TARDIS was being held in an online auction by [[GalMart]] when it was claimed as salvage. During the bid, the Doctor pointed out that he still had the key on him, leaving the winner [[WinnerBoi]] with a ship he couldn't access. While pretending to hand over the deed of ownership to GalMart, he instead wrote a Trojan virus in [[Ancient High Gallifreyan]] to infest the GalMart systems. He compelled the GalMart computer to purchase the anti-Trojan, and to declare the TARDIS as a bootleg or counterfeit item, but to transfer the money to WinnerBoi for the amount he had paid to buy the TARDIS. ([[PROSE]]: ''[[Buyer's Remorse (short story)|Buyer's Remorse]]'')
 
=== Clara rejoins ===
{{section stub|Info from ''[[Selfie (comic story)|Selfie]]'' needs to be added}}
Reuniting with Clara for a farewell trip, the Doctor took her to a space-bound [[Orient Express (spacecraft)|Orient Express]]. He later confessed to her that he had chosen the destination with an inkling that something exciting would happen after having been lured with [[The Big Bang (TV story)|phone calls]], mysterious summons and free train tickets. After discovering the death of [[Pitt (Mummy on the Orient Express)|an elderly passenger]], and urging himself to investigate, the Doctor went to the engine room to examine the dead passenger's [[Excelsior Life Extender]], meeting [[Perkins (Mummy on the Orient Express)|Chief Engineer Perkins]] in the process, and learned the legend of the [[Foretold]]. Seeking advice from [[Emile Moorhouse]], a fellow passenger who was a Professor of Alien Mythology, the Doctor soon discovered a second death had occurred in the kitchen.
 
Confronting Captain [[Quell]] with his theory, but getting ignored, the Doctor joined Perkins and Moorhouse in the engine room to research the deaths. Calling Clara to update her, the Doctor discovered that she and [[Maisie Pitt]] were trapped in a storage cart with a sarcophagus. Fearing that Clara was trapped with the Foretold, the Doctor tried to rewire the door open, only to find the sarcophagus empty, and himself under arrest by the Captain for being a stowaway.
 
However, after witnessing a third death first hand, Quell realised that the Doctor was right and allied with him, just as the Doctor [[deduce]]d the true nature of the Orient Express; the passengers were all experts and scientists in specific fields of study, gathered there to study the Foretold. With a lab revealed and the hologram passengers disappearing, the train's computer, [[Gus (Mummy on the Orient Express)|Gus]], gave the scientists the necessary instructions and equipment. Losing Moorhouse to the Foretold, the Doctor and Perkins figured out that the Foretold was targeting the weaker passengers after looking at the medical history of the previous victims, just as Quell was killed by the creature, as he had [[post-traumatic stress]], but not before he gave the Doctor the necessary description to defeat the Foretold.
 
[[File:The Doctor Foretold.jpg|thumb|The Doctor allows the Foretold to prey on him. ([[TV]]: ''[[Mummy on the Orient Express (TV story)|Mummy on the Orient Express]]'')]]
Realising that Maisie was next due to her breakdowns, the Doctor told a reluctant Clara to bring Maisie to the lab. Arriving there, the Foretold appeared to Maisie, but the Doctor saved her by implanted a replica of her grief into his head, confusing the Foretold into thinking the Doctor was Maisie. Deducing that the Foretold was an ancient soldier augmented with technology, the Doctor surrendered, and, after a final salute, the ancient soldier crumpled to dust, with only the technology that kept him alive remaining. With the objective completed, Gus released the air out of the cabin, but the Doctor beamed all the dying passengers into the TARDIS, and tired to hack Gus to find out who had created him, but this trigged a security measure, causing the train to self-destruct. Dropping everyone but Clara and Perkins off at the nearest civilised planet, the Doctor waited for Clara to awaken on a beach before explaining everything.
 
Back in the TARDIS, the Doctor invited Perkins to travel with him, but Perkins politely declined and he and the Doctor bade each other goodbye. Reflecting on a conversation she had with Maisie, Clara, having forgiven the Doctor, decided to continue travelling with him, telling the Doctor that her leaving was all Danny's idea. ([[TV]]: ''[[Mummy on the Orient Express (TV story)|Mummy on the Orient Express]]'')
 
Picking up a signal, the TARDIS arrived on the [[Quartz Wastes]] of [[Asmoray]]. Although the Doctor believed it was an uninhabited wasteland, Clara pointed out there was a harvester nearby extracting [[electricity]] from the quartz. The Doctor and Clara were brought aboard the harvester by two workers, where beings within the electricity had broken through and killed four workers. Their leader, [[Luther (The Body Electric)|Luther]], was insistent on continuing their work regardless. Investigating, the Doctor and Clara found the creatures were only attacking because they were being sucked into the harvester's storage batteries. With Clara's help, the Doctor was able to free the electricity beings back into the quartz. ([[COMIC]]: ''[[The Body Electric (comic story)|The Body Electric]]'')
 
Heading for [[Rome]], the Doctor and Clara wound up in a Germanic forest, where they were apprehended and taken into a nearby encampment. There they learnt that [[robot]]ic [[mosquito]]es were spreading [[disease]] and killing off dozens of [[soldier]]s. Tracking the energy fields of the mosquitoes to a tower in the woods, the Doctor discovered the occupants were using the mosquitoes to search for a cure to a plague infecting their own world. The Doctor convinced them to leave. Although Clara was worried about the rest of the sick soldiers, the Doctor told her to leave them, saying that everybody dies. ([[PROSE]]: ''[[Silver Mosquitoes (short story)|Silver Mosquitoes]]'')
 
The Doctor and Clara travelled to the [[Sands Hotel]] in [[1964]] [[Las Vegas]] after the Doctor found some tickets to see [[Frankie Seneca]] in a drawer. After proving to be a surprisingly good gambler, he caught the attention of [[Johnny Dragotta]], who accused him of cheating. However, they were distracted when [[Mikey Nero]], who was thought to have been killed, arrived, demanding control of the hotel. The Doctor unmasked Mikey as a disguised agent of the [[Cybock Imperium]], who began attacking the hotel. While trying to immobilise it, the Doctor was grabbed and throttled by the Imperium, but was saved by [[Sonny Lawson]].
 
The Doctor and Sonny discovered the Imperium's ships, and rescued Clara from their captivity. Clara gave the Doctor a [[Time Gun of Rassilon]], which had been in the alien's possession. As the Imperiums attacked the hotel, the Doctor intervened and offered the aliens a game of Russian roulette with the gun. Although they agreed, the Doctor knew the gun would not work on a Time Lord, and it would self-destruct if one attempted to use it on a Time Lord. When the aliens' leader, Kronos, attempted to shoot the Doctor with the gun, it accordingly wiped away his timeline, and the other Cybocks with him. The Doctor, Clara and Sonny then finally went to see Seneca perform. ([[COMIC]]: ''[[Gangland (comic story)|Gangland]]'')
 
[[File:TwelveBugsUT.jpg|thumb|left|The Doctor is attacked by Aranox bugs. ([[COMIC]]: ''[[Unearthly Things (comic story)|Unearthly Things]]'')]]
The Doctor and Clara attempted to go to [[Margate]] but ended up landing in [[1845]] [[Derbyshire]], where they encountered a woman called Charlotte. They helped her to her lodge, the North Lees Hall. There, the Doctor accepted an offer from Lord [[Malborough]] to stay at the house upon learning of a mysterious "dreaming sickness". That night, the Doctor was attacked by a possessed servant, which he suspected to be linked to the sickness. The following day, during Malborough's preparations for a house party, the Doctor and Charlotte discovered a salvaged space vessel in a barn, the Doctor deducing that there was an alien influence to the sickness. They crashed the party to find Clara and the guests being attacked by a possessed Malborough with insects. Escaping the possessed guests, the Doctor and Charlotte discovered the source of the possessions was an [[Aranox]], taking everyone's psychic energy. The Aranox refused to take mercy and attacked the Doctor and Charlotte with insects. However, Malborough was freed from his possession and attacked the Aranox with a lantern, setting it on fire and breaking the psychic control. As the house burned down, everyone escaped, but the Doctor felt guilty for the Aranox as it had been the last of its kind. As Charlotte left for a village with Malborough, she revealed her full name was [[Charlotte Brontë]]. Clara was humoured to learn that the Doctor and the events of the story had been the inspiration for ''Jane Eyre'', and suggested to him they go get some fish and chips. ([[COMIC]]: ''[[Unearthly Things (comic story)|Unearthly Things]]'')
 
Taking Clara to the [[Taj Mahal]] in [[India]] for a holiday, the Doctor was chosen to act as a hostage by [[Stellar Nexus]] while Nexus tried to get payment for Earth's supposed tax bills. When the Doctor challenged Nexus's claim by pointing out the illogic in his statement, and then insulted him by asking why he had never heard of Nexus's Empire, the Doctor was locked in a cell while an illusion of him was set against a dragon in a gladiator battle. When Clara managed to pilot the TARDIS into the Doctor's cell, the Doctor used his sonic screwdriver to deactivate Nexus's illusions, exposing that Stellar Nexus was a child-sized con artist whose entire Empire was an illusion. Sending the defeated Nexus away, the Doctor decided to treat Clara to a [[curry]]. ([[COMIC]]: ''[[Empire's Fall (comic story)|Empire's Fall]]'')
 
The Doctor took Clara to see the [[Lights of Tanzarr]], but instead found that the [[Nameless Mist]] had entered his dimension and was threatening to devour the cosmos. Originally wanting to flee, the Doctor was convinced by Clara to save the inhabitants of [[Ferrous-Ferra]], and was inspired to recruit [[Cold Steel]] to headline the "loudest rock show in history of sound". While Clara triangulated the transmissions to cover the local galaxy, the Doctor used the loud music to thwart off the Nameless Mist. With the day saved, the Doctor returned to the concert to celebrate with crowd surfing. ([[COMIC]]: ''[[The Big Hush (comic story)|The Big Hush]]'')
 
Trying to return Clara home, the Doctor instead landed in [[Bristol]] when the [[Boneless]] began draining power from the TARDIS, drawing it off course and causing the exterior to shrink. Sending Clara to find the cause, the Doctor re-entered the TARDIS to study the shrinking effect, only for the TARDIS to shrink further, trapping him inside. Equipping Clara with his [[psychic paper]] and [[sonic screwdriver]], the Doctor used nanotechnology to hack into Clara's optic nerve and establish a visual contact with the outer world. After Clara recruited the aid of a local named [[Rigsy]], pretending to be the Doctor while doing so, the duo discovered that creatures from a two-dimensional universe were killing and dissecting missing locals to understand their three-dimensional bodies.
 
After discovering that Clara had lied to him about Danny's approval, the Doctor realised that a mural dedicated to local missing people was in fact the missing people, killed and worn by the creatures as camouflage. With Clara leading a gang of surviving community servers, the Doctor theorised that the creatures were trying to communicate, and that the deaths were but a mere misunderstanding. When the theory was proved wrong, the Doctor invented a [[2Dis]] — a device that could reverse the creatures' flattening abilities — as Clara and her gang retreated to an underground tunnel.
 
[[File:Twelve Tiny TARDIS Railroad Track Peril.jpg|thumb|Failing to maneouver his shrunken TARDIS from the railway line, the Doctor hears a train approaching. ([[TV]]: ''[[Flatline (TV story)|Flatline]]'')]]
After Clara accidentally dropped the TARDIS onto a train line, the Doctor activated the TARDIS' [[siege mode]] to protect it from an oncoming train. Now unable to even open the doors, which had been removed by the activation of siege mode, and with the life support systems failing as the power drain continued, the Doctor congratulated Clara for being worthy of the title Doctor, unsure if she could hear him or even if she was still alive. Clara and Rigsy were able to trick the creatures into supplying the TARDIS with the necessary power to restore it to full working conditions. Naming his adversaries the Boneless, and declaring himself as "The man that stops the monsters." the Doctor banished them back to their home universe. The Doctor then took the survivors to the surface. ([[TV]]: ''[[Flatline (TV story)|Flatline]]'')
 
[[File:The Eye of Torment.jpg|left|thumb|The Doctor threatens the Umbra. ([[COMIC]]: ''[[The Eye of Torment (comic story)|The Eye of Torment]]'')]]
The Doctor landed on the ''[[Pollyanna]]'', the first of the [[Ninth Era]] [[sunship]]s, which had been on an expedition to circumnavigate [[Sol|the Sun]]. Seeing one of the [[Umbra (The Eye of Torment)|Umbra]] come out of the Sun and enter a [[plasma intake]], the Doctor rushed to the [[plasma lab]] and carried the injured [[Professor]] [[Alice Dubrovnik]] to safety. The Umbra, who had been trapped in the [[chromosphere]] for millions of years, began swarming the ''Pollyanna'', anchoring the ship to the Sun to try and hijack it and use it as a way of reaching Earth. As the Umbra on board took on more humans as vehicles, the Doctor was ejected out of a plasma intake to attract the Umbra to his regret. He set up the final link to Alice's [[graviton inverter]] on the hull of the ship, allowing Alice to briefly boost the inverter and create a secondary [[gravity]] envelope, which inverted the gravity and the heat, freezing the Umbra on the ship to death. ([[COMIC]]: ''[[The Eye of Torment (comic story)|The Eye of Torment]]'')
 
[[File:DWM_482_12_and_Sontaran.jpg|thumb|The Doctor is identified by Sontarans. ([[COMIC]]: ''[[The Instruments of War (comic story)|The Instruments of War]]'')]]
The Doctor tried taking Clara to the [[frost fair]] in [[1641]], but instead, was drawn off course and landed in the [[Sahara Desert]] in [[1941]], where they were captured by [[Nazi]]s. While requesting business with Field Marshall [[Erwin Rommel|Rommel]], the Doctor learnt from Rommel that [[Germany]]'s allies, the [[Tuareg]] tribesmen, had made new extraterrestrial allies. The Doctor believed it was urgent to see the Tuareg and went with Rommel to meet them. After being taken to the tribe's chieftain, [[Bhaki]], to see these "men from the stars" Bhaki introduced the Doctor and Rommel to the Tuareg's new allies, the [[Sontaran]]s. The Sontaran [[commander]] [[Kygon Brox]], believing the Doctor was looking for the Sontaran world engine weapon, the [[Warsong]], tried interrogating the Doctor with a [[mind scythe]]. The Doctor made the link go the other way, and Kygon explained the history of the weapon to the Doctor. He told the Doctor that the Warsong was taken to Earth, and that there was someone seeking the weapon after signals from it began increasing exponentially. The Doctor realised that the "highly decorated" Nazi officer [[Heinz Bruckner]] wasn't who he claimed he was, but a [[Rutan Host|Rutan]] [[spy]] and watched from a distance as the Warsong was triggered.
 
Realising that Bruckner took Clara with him to the Warsong's activation, the Doctor came up with a plan to converge the [[Allies|Allied]], Axis and Sontaran forces towards the still-forming Warsong to distract Bruckner while he and Rommel sneaked into the Warsong and broke through its defences. The Doctor stopped Bruckner from conducting the millennia-old preset programming of the Warsong by using a Sontaran [[osmic projector]] to send Bruckner's trigger mechanism through time. Rommel threw Bruckner into the Warsong, killing him, while the Doctor destroyed the "orchestra" of the Warsong by using his sonic screwdriver to blow it up. Afterwards, he brought Clara to the frost fair. ([[COMIC]]: ''[[The Instruments of War (comic story)|The Instruments of War]]'')
 
After spending some time on his own, the Doctor landed in London, only to find it and the rest of the world overrun by trees after [[Maebh Arden]], a student of [[Coal Hill Year 8 Gifted and Talented Group]] under Clara and Danny's care, looked for the Doctor after hearing about him in what Maebh believed was a thought that came from Clara. With his theories constantly being proven wrong, the Doctor came to the conclusion that the trees' sudden overgrowth was an act of aggression, while also dealing with Clara's students in his TARDIS after Clara and Danny arrived to collect Maebh, only for Maebh to slip away in the commotion, just as the Doctor noticed her homework had predicted the events of that day.
 
[[File:Twelve Talks to Trees.jpg|thumb|left|The Doctor evokes the appearance of plant entities with his sonic screwdriver. ([[TV]]: ''[[In the Forest of the Night (TV story)|In the Forest of the Night]]'')]]
Following Maebh deeper into the forest, the Doctor discovered that a sentience identifying itself as "the life that prevail[ed]" had caused the overgrowth, in preparation for a devastating [[solar flare]] about to hit the Earth. Believing Earth doomed, Clara inquired him to use the TARDIS as a lifeboat, only to inform him that she had said that to get him back to his TARDIS so he could survive the catastrophe alone. Despite some reluctance, Clara eventually convinced him to leave. Immediately afterwards, having discovered upon further reflection that the trees were going to absorb the harmful solar flares by pumping the [[atmosphere]] with excess [[oxygen]], "like a massive, highly inflammable air bag", the Doctor returned to Clara and explained his discovery to the Gifted and Talented Group.
 
When he was informed of a government operation aiming to destroy the trees, the Doctor opened every mobile network on the planet to allow Maebh the opportunity to deliver a speech written by the Gifted and Talented Group to leave the trees alone. With Danny taking the children to their homes, the Doctor and Clara watched the trees that grown around the world harvesting and extinguishing the solar fire in the TARDIS, and then returned to watch the trees disappear on Clara's balcony. ([[TV]]: ''[[In the Forest of the Night (TV story)|In the Forest of the Night]]'')
 
[[File:TwelveSonicsSI.jpg|thumb|The Doctor works against the Hyper-Kraken. ([[COMIC]]: ''[[Space Invaders! (comic story)|Space Invaders!]]'')]]
The Doctor and Clara travelled to a galactic [[auction]] in Earth's orbit where unclaimed storage was being bid on, with the storage pod belonging to [[Hyphen T Hyphen]], a reclusive collector, containing a mother [[Rigellan Hyper-Kraken]], which began killing everyone when the pod was opened. Before the mother Hyper-Kraken's eggs could hatch, the Doctor widened the [[dimensional shunt]]'s focus on the Hyper-Kraken, her eggs and the storage pods and safely transported them elsewhere. ([[COMIC]]: ''[[Space Invaders! (comic story)|Space Invaders!]]'')
 
The Doctor attempted to take Clara to [[Blackpool]], but they ended up arriving in [[2089]], by which point the pleasure beach had become an overgrown jungle. The Doctor befriended and named [[Meghan (All the Empty Towers)|Meghan]], a wounded donkey shot by a man called [[Triss (All the Empty Towers)|Triss]], who was planning a hunting trip in hover pods powered by the Blackpool Tower. The Doctor shut down the power, ending Triss' hunting plans. The Doctor and Clara had a dance in a ballroom, and then he enjoyed a play in the water with Meghan. ([[PROSE]]: ''[[All the Empty Towers (short story)|All the Empty Towers]]'')
 
[[File:Twelve Clara attacked.jpg|left|thumb|The Doctor and Clara are attacked by hybrid animal subjects. ([[COMIC]]: ''[[Blood and Ice (comic story)|Blood and Ice]]'')]]
The Doctor and Clara went on a tour of [[Snowcap University]] in [[Antarctica]] in [[2048]]. While taking a [[helicopter]] ride, they learnt that one of the students, [[Polly Evans]], had stayed behind at the end of term to join the classified [[Project Sub-Zero]]. When another student, [[Quinn Norton]], who also a part of Project Sub-Zero, was killed in a helicopter crash the Doctor and Clara narrowly avoided being on along with Polly's father [[George Evans|George]], they returned to Snowcap U to investigate. With the help of the [[spy]] [[Paul South]], the Doctor found an ice cavern where the missing students had been experimented on, engineered by Dr [[Patricia Audley]] to survive in extreme cold. To their shock, the Doctor and Clara also met [[Winnie Clarence]], one of Clara's splinters who refused to accept her only purpose was to save him. Paul and Winnie released most of the imprisoned humans from captivity.
 
The Doctor transmitted a signal with his sonic causing Dr Audley's animals to go wild. After feigning betrayal of the two, Winnie threw the Doctor the key to free the hybrid subjects from their cells, and saved the Doctor's life by pulling Dr Audley into a vat of liquid [[ice]] after Audley pulled a gun on him. Dr Audley was killed, but Winnie survived when she unwittingly had a syringe of Dr Audley's experimental [[blue blood]] serum injected into her, allowing her to live inside the ice. Clara realised that this meant that not all of the splinters died saving the Doctor, and several of them had lives of their own. ([[COMIC]]: ''[[Blood and Ice (comic story)|Blood and Ice]]'')
 
=== The darkest hour ===
The Doctor rejoined Clara for a trip, where she suggested they go see a [[volcano]]. As the Doctor set the TARDIS to go, Clara attempted to put a [[Mood drug|mood patch]] on his neck, but the Doctor realised what she was doing and turned it on her. Not realising she was drugged, Clara imagined being at the volcano and throwing all the Doctor's TARDIS keys into lava, to blackmail him to save Danny, who had been killed in a road accident. The Doctor refused, and Clara came out of her dream state after destroying all the TARDIS keys. Despite her betrayal, the Doctor agreed to search for an afterlife to find Danny.
 
The Doctor and Clara arrived at [[3W]], which held dead bodies in water tanks. They were greeted by {{Gomez}}, who identified herself as a greeting droid and kissed the Doctor as part of her greeting routine. They met [[Chang (Dark Water)|Dr. Chang]], who showed them the use of [[dark water]] in the mausoleum. Clara received a call from Danny, who was in the [[Nethersphere]], and the Doctor and Chang left her to take it.
 
[[File:TwelveShockedDW.jpg|thumb|The Doctor is horrified to realise that his oldest enemy has returned. ([[TV]]: ''[[Dark Water (TV story)|Dark Water]]'')]]
The Doctor and Chang discovered that the water tanks that held the bodies were being drained by Missy, who killed Chang and revealed that all the tanks held [[Cyberman (Mondas)|Cybermen]], who were preparing to invade Earth. Escaping the building, which he discovered [[St Paul's Cathedral]], the Doctor tried to warn away nearby people, but Missy called out his warnings as insanity, and told him it was too late. The Doctor asked for her identity, and, to his shock, Missy revealed she was [[the Master]], ([[TV]]: ''[[Dark Water (TV story)|Dark Water]]'') before she and the Doctor were apprehended by [[UNIT]] and brought aboard the plane [[Boat One]], where the Doctor was made President of Earth to battle the Cybermen. Missy overpowered UNIT, killed Osgood, and attempted to kill the Doctor by blowing up the plane, but the Doctor survived his fall to Earth by skydiving into the TARDIS. He travelled to a cemetery and reunited with Clara, who was comforting a converted Danny. Missy arrived and, as a "birthday present", gave the Doctor control of all the Cybermen.
 
[[File:TwelveSalutes.jpg|thumb|left|The Doctor salutes his old friend. ([[TV]]: ''[[Death in Heaven (TV story)|Death in Heaven]]'')]]
Missy planned to turn the Doctor into the leader of the new army, intending to prove that the two of them were not that different after all, believing that she had put him in the impossible position of either accepting control of the army and using it to "save" the universe or letting humanity die and conquer the universe as the Cybermen. However, reflecting on his past, the Doctor realised that he was just a man in a box who travelled around to help where he could, proclaiming that he was not a good man, a bad man, the leader of an army or a President. He then turned command of the army over to Danny, realising that the teacher had held on to his love for Clara even with his emotions deactivated, who led the Cybermen into the clouds where they self-destructed and stopped the rainfall from converting the living. A devastated Missy told the Doctor he could find [[Gallifrey]] in its original location with coordinates she provided, but Clara threatened to kill Missy for what she had done, until the Doctor prepared to do it himself. However, a rogue Cyberman disintegrated Missy instead, ([[TV]]: ''[[Death in Heaven (TV story)|Death in Heaven]]'') though the Doctor knew she had found a way to survive. ([[TV]]: ''[[The Magician's Apprentice (TV story)|The Magician's Apprentice]]'') The Doctor realised it was his old friend [[the Brigadier]] — resurrected as a Cyberman — helping him again. The Doctor saluted the Brigadier, fulfilling a lifelong wish of his old friend, noting that the Brigadier would never be anywhere else but by his side when Earth and the Doctor faced their darkest hour.
 
[[File:TwelveClaraGoodbye.jpg|thumb|The Doctor and Clara part ways. ([[TV]]: ''[[Death in Heaven (TV story)|Death in Heaven]]'')]]
The Doctor entered the coordinates Missy gave him into the TARDIS and looked at his location, expecting to find Gallifrey. However, it turned out the coordinates were false and led to nowhere. With his only way to find Gallifrey gone, the Doctor attacked the TARDIS console in a furious rage, before breaking down emotionally. Meeting up with Clara in a café, and believing that she was back with Danny, the Doctor lied to her that he had found Gallifrey so as to allow her to continue with her life. Upon hearing this, Clara told him that she was happy and ready to settle down with, and they both bid farewell and parted ways. ([[TV]]: ''[[Death in Heaven (TV story)|Death in Heaven]]'')
 
=== Dreaming of Santa ===
Sometime later, the Doctor was attacked by a [[dream crab]], which put him into a scenario where he was brooding alone in his drifting TARDIS, ([[TV]]: ''[[Last Christmas (TV story)|Last Christmas]]'') and was snapped out of his funk as when he heard [[Santa Claus]] knocking on the TARDIS door, asking the Doctor what he wanted for Christmas. ([[TV]]: ''[[Death in Heaven (TV story)|Death in Heaven]]'')
 
The Doctor travelled to Clara's home and collected her from her rooftop, where she had also encountered Santa. Urging her to believe in him, they arrived at a North Pole base, which they found was under attack from dream crabs. Santa arrived to help with the problem, but Clara was attacked by a crab and fell into a dream state. As no one could find a way to remove the crab from her face, the Doctor let himself be attacked by one to get her out of her dream before the crab could kill her.
 
[[File:Twelve Pulling Santa's Sleigh.jpg|thumb|left|Fleeing a dream world, an ecstatic Doctor gets to pull Santa's [[sleigh]]. ([[TV]]: ''[[Last Christmas (TV story)|Last Christmas]]'')]]
Entering Clara's dream, the Doctor found she was dreaming of spending Christmas with Danny, and learned that Danny was dead. The Doctor urged her to break out of the dream, after Danny bid her farewell. Waking up in the base, the Doctor came to the realisation that everyone in the base was dreaming, having been attacked by crabs after they arrived. They woke up from the dream and the Doctor and Clara prepared to leave, but Clara reminded the Doctor of Santa having been on her roof, and he realised they were still dreaming from different places and times. The infected personnel in the base began to attack the survivors, however, everyone managed to escape by dreaming Santa was flying them home. The Doctor, Clara and the base scientists flew over London as they each woke up back in their own times.
 
Waking up where he had been, the Doctor travelled to Clara's home and removed the dream crab attached to her, only to find it had been sixty-two years since he left her and she was now an old woman. Clara filled her in on the years, but the Doctor felt remorseful of leaving her when he did. Santa suddenly appeared and asked the Doctor what he'd do if he had another chance, and the Doctor woke up from his dream, this time for real. He saved the younger Clara from the crab. Spurred on by what could have happened to her, the Doctor invited her to resume her travels with him, and she accepted. They set off together in the TARDIS, the Doctor remarking that he rarely got second chances with his companions, and commenting that he didn't know who to thank for this one. ([[TV]]: ''[[Last Christmas (TV story)|Last Christmas]]'')

[[File:Clara Birthday Comic Back Up Story.jpg|thumb|The Doctor reveals the alien duplicates of Clara. ([[COMIC]]: ''[[The Partying of the Ways (comic story)|The Partying of the Ways]]'')]]
The Doctor tried to throw Clara a surprise birthday party with varying incarnations and forms of herself, but after Clara noted the rules of time preventing one from meeting themselves, he admitted they were just disguised aliens. ([[COMIC]]: ''[[The Partying of the Ways (comic story)|The Partying of the Ways]]'') They next went to [[Cinema Paradoxo]], which had every movie ever playing infinitely. The Doctor chose to see a silent film, which turned out to star actual [[Silent]]s, resulting in them forgetting the film. ([[COMIC]]: ''[[Silver Screenesis (comic story)|Silver Screenesis]]'')
 
After Clara accidentally freed the [[Djinx]] from his imprisonment, the Doctor was trapped in his TARDIS by the vengeful entity. Sending Clara instructions on her phone, the Doctor was able to instruct Clara on how to defeat the Djinx and free himself. ([[COMIC]]: ''[[Doctor in a Bottle (comic story)|Doctor in a Bottle]]'')
 
Following Clara's request to meet the Greek storyteller [[Homer]], the Doctor found himself drugged by an innkeeper and bound to a post with Homer and Clara to be fed to a bunch of [[Cyclops|Cyclopes]]. Before he could be eaten, however, the Doctor managed to convince the  Cyclopes to listen to Homer's harp, and the young man's music soothed the hungry Cyclopes to sleep. Using a [[Sub-conscience reading reality device]], the Doctor discovered that the beasts were refugees from a war that had destroyed their world and, after using his device to convert them to a vegetarian diet, the Doctor let Clara convince them to live in peace in the hills.

The Doctor and Clara visited the liberation of Paris in [[1944]], where they thwarted a plan by the [[Darapok Empire]] to brainwash humanity into destroying itself by destroying their transmitter on the [[Eiffel Tower]], and then frightening them off. ([[COMIC]]: ''[[Trust (comic story)|Trust]]'')
 
[[File:TwelveStudiesSOTJ.jpg|thumb|left|The Doctor studies the creatures of Unnamed BX-4. ([[COMIC]]: ''[[Spirits of the Jungle (comic story)|Spirits of the Jungle]]'')]]
The Doctor learnt from a friend of his, [[Hitch (Spirits of the Jungle)|Hitch]], that a sentient super-weapon called the [[Hadax Ura]] had gone missing. Hitch was putting together a recovery team and needed the Doctor's technical expertise. The Doctor agreed to join the team, dragging Clara away from her class to assist. As the ship carrying the team headed for the planet carrying the weapon, [[Unnamed BX-4]], the Hadax Ura shot the ship down, revealing the weapon's location, but everyone on board was able to escape with [[jetpack]]s. Clara was attacked by [[pterosaur]]s and dropped into [[the Jungle]].
 
The Doctor went off on his own to look for Clara, and found Clara with an [[organic avatar]] who had taken on the appearance of Danny. The avatar told them that the Hadax Ura had been "devouring" the Jungle, and turning its indigenous life into an army, and asked them either to destroy the weapon, or to take it elsewhere. The Doctor realised that this meant it intended to end the war between the [[Hub Alliance]] and the [[Axis Worlds]], and the Hadax Ura began augmenting the crew to become its foot soldiers. Believing it had augmented Clara as well, the Hadax Ura had actually linked the Jungle's computer systems to its own after augmenting the avatar. The avatar appeared to shut down the Hadax Ura and its augmented soldiers, but in fact, the Hadax Ura had tricked Hitch's team to bring it on board the lander as a means of escape for the Hadax Ura. The Doctor took his jet pack to infiltrate the lander, and found the Hadax Ura had taken over Hitch's body. Realising that Hitch's mind had been completely overwritten by the Hadax Ura, the Doctor ejected the Hadax Ura, and Hitch's body, out of the lander's airlock, burning both up on re-entry unprotected. ([[COMIC]]: ''[[Spirits of the Jungle (comic story)|Spirits of the Jungle]]'')
 
Coming to pick up Clara, the Doctor was persuaded to play boards games instead. Losing, the Doctor broke the [[Laws of Time]] by repeatedly going back in time to the moment he arrived so he could win a game before Clara; this desire consumed him, resulting in the Doctor becoming ragged by his 75th try. Unaware of the Doctor's actions, Clara headed for the TARDIS. ([[COMIC]]: ''[[The Board Games (comic story)|The Board Games]]'')
 
The Doctor and Clara arrived in [[Highgate Cemetery]] in [[1972]], where intruding upon a cult meeting, they were attacked by vampire-like creatures called the [[Corvid]]s, which petrified the TARDIS and fed on people's psychic essence, but were trapped inside the cemetery. He discovered that Clara's exposure to his time stream had rendered her toxic to the Corvids' powers, and that exposing themselves to her left a psychic corridor open. Using the psychic signature of the dead amplified by the ley line the cemetery was built on, the Doctor banished the Corvids back to the time vortex. ([[COMIC]]: ''[[The Highgate Horror (comic story)|The Highgate Horror]]'')
 
=== The Hyperions rise again ===
[[File:TwelveHyperionsTHE.jpg|thumb|right|The Doctor is swarmed by the Scorched. ([[COMIC]]: ''[[The Hyperion Empire (comic story)|The Hyperion Empire]]'')]]
The Doctor and Clara arrived in [[2015]] London to find it as a burnt wasteland. Although the Doctor knew they were in 2015, Clara believed they'd gone off-course. Clara wandered into [[Westminster Abbey]] as the Doctor investigated the streets. Scanning the streets, he found traces of human DNA amongst the ashes. He was threatened with a gun by a panicked man. Overpowering him with [[Venusian karate]], the Doctor learnt from the man that "the scorched" were rising. The Doctor observed that there was no wind in the air, whereupon the man was attacked and possessed by [[Hyperion (species)|Hyperions]]. The Doctor then found himself facing many Hyperion-possessed humans, but was able to defeat them with the help of Clara and [[Sam (The Hyperion Empire)|Sam]], a [[firefighter]].
 
Sam brought the Doctor and Clara to the [[London Underground]], where people had taken refugee from the Hyperion invasion. The Doctor, reappointed by UNIT as President of Earth, learnt that the Hyperions had divided England up with firewalls, particularly operating machinery in [[Sussex]]. The Doctor, Clara and Sam bypassed the Sussex firewall via TARDIS and found that captured humans were being enslaved by the Hyperions to build a fusion web. Clara tried to intervene, but in doing so caused Hyperion "angels" to appear. Fleeing back to the TARDIS, an angel got on board, but Sam knocked her out by spraying her with a fire extinguisher. Deducing that the angel had been transmogrified by the Hyperions, the Doctor bio-linked her to the TARDIS telepathic circuits to restore her human consciousness. The TARDIS materialised by the sun, where the Hyperions were building the fusion web to consume its energy. Although the Doctor believed they were out of range, the web was already powerful enough to attack the TARDIS.
 
[[File:Twelve recovers essence.jpg|thumb|left|Having had enough noble sacrifices, the Doctor recovers Weir's psychic essence. ([[COMIC]]: ''[[The Hyperion Empire (comic story)|The Hyperion Empire]]'')]]
Dra-Khan, a Hyperion warlord, stormed the TARDIS and revealed the Hyperions survived the destruction of Hyperios by hiding on [[Neptune (planet)|Neptune]]. The angel, in actuality the reanimated human, [[Weir (The Hyperion Empire)|Jane Weir]], regained her consciousness and attacked Dra-Khan and the other Hyperions, driving them away. The Doctor persuaded Weir to join their side, and after defeating an onslaught of Scorched in London, revealed he had weaponised a cold bomb to defeat the Hyperions. Back at the Sussex firewall, the Doctor released the human slaves from captivity as Clara and Sam attacked the base. Sam attempted to detonate the cold bomb, but it failed and he was killed. The Doctor conceded that the Hyperions had won, as the fusion web was completed. But when it was activated, he revealed that the bomb had merely been a distraction so that he could hack the TARDIS into the web and pull the Hyperions five billion years into the future, where the sun died. As the web began collapsing, the Doctor and Clara escaped to the TARDIS as Weir held off the Hyperions. However, unwilling to let anyone else die after Sam's death, the Doctor pulled Weir's psychic essence from the TARDIS' telepathic circuits, allowing her presence to be with her family.

Arriving on the ''[[SS Berry Gordy]]'' in the [[53rd century]], the Doctor and Clara saved pop-star [[India Summer]] from being kidnaped by a band of [[Skink]]s hired by her manager, [[Gavor Vek-Haart]]. ([[COMIC]]: ''[[Hyperballad (comic story)|Hyperballad]]'')
 
Returning to [[Coal Hill School]] to pickup Clara, the Doctor found the world had been gassed into a deep sleep by the [[Somnosian]] Empire. Using an antidote to awaken the populace, the Doctor allowed the Somnosians to retreat when the armed forces arrived. ([[COMIC]]: ''[[Beauty Sleep (comic story)|Beauty Sleep]]'')
 
The Doctor and Clara responded to a party invitation from [[Susan Foreman]], only to discover they had been lured into a trap by the [[Celestial Toymaker]], who explained that his [[Celestial Toyroom|Toyroom]] was breaking down from old age, and that he had entrapped the Doctor for help. Seeing a kinship with his enemy, the Doctor relinquished his TARDIS to the Toymaker, knowing that it was the only way to help him. Escaping to the control room, the Doctor jettisoned the [[Zero Room]] with the Toymaker still inside, allowing the Toymaker to have it as his new Toyroom. ([[COMIC]]: ''[[Relative Dimensions (comic story)|Relative Dimensions]]'')
 
The Doctor and Clara arrived in a forest on a [[Planet (The Dragon Lord)|planet]], where the TARDIS was stolen by [[dragon]]s. Navigating to a nearby village, they learned from the Lord [[Mortigan]] that they were on a planet designed to resemble medieval times, with the dragons being the planet's natural inhabitants, which had been [[Genetic engineering|genetically modified]]. The dragons had been freed from being inhibited by [[inhibitor chip]]s by a person known as the [[Dragon Lord]], who aimed to wipe out the townspeople, having already killed the royalty. Although the Doctor declared his intent to leave and let the townspeople get what they "deserved" for enslaving the dragons, Clara reminded him that he shouldn't decide which lives were worth saving. The Doctor, Clara and the town's remaining lords set off to reason with the Dragon Lord. Along the way, they ran into a baby hatchling, but Lord Mortigan killed it, causing its parents to attack the party. The Doctor was separated from Clara in the chaos, and found a dragon which had been injured by a booby trap. The Doctor found that the dragon did not possess a chip, casting doubt over his belief that the Dragon Lord was controlling their chips. Reuniting with Clara at the [[Red Castle]], they found that the Dragon Lord had been killed, believing they would have been grateful to him for liberating them. The Doctor and Clara retrieved the TARDIS from the dragons' treasure hoard and left, calling rescue ships to evacuate the planet of humans to allow the dragons to live in peace. ([[COMIC]]: ''[[The Dragon Lord (comic story)|The Dragon Lord]]'')
 
The Doctor and Clara were summoned by [[Harry Houdini]], and found themselves in a crystalline [[computer program]] inside a [[crystal ball]] which fed on their despair. The program set up theatrical death traps with no way out so their minds could be ripened for it, but the Doctor, Clara and Houdini escaped. The Doctor revealed the virtual environment with his [[sonic screwdriver]]. The Doctor, Clara and Houdini then fought back by imagining what made them feel the most free, which shattered the prison and returned them to the real world. They found the owner of the crystal ball prison, [[Diamanda]], had been completely consumed by the crystal ball's power and killed. When Houdini regretted his inability to commune with the dead, the Doctor and Clara reassured him that his legacy would be remembered forever. ([[COMIC]]: ''[[Theatre of the Mind (comic story)|Theatre of the Mind]]'')
 
The Doctor had planned to create an entry for ''[[The Great Martian Bake-Off]]'', but while in the middle of a phone call with Clara, found she had gone missing at a [[Halloween]] Fayre at Coal Hill School. At Coal Hill, the Doctor had found that superstitions had been coming true, and after getting rid of a bear, followed clues to find what happened to Clara. At the end of the trail of clues, the Doctor found the mischievous time traveller [[Miss Chief]], who told the Doctor that she sent Clara back in time with the Witchfinder General [[Matthew Hopkins]], who threw Clara into the water to see if she was a witch. Miss Chief saved Clara's life in the [[17th century]], and back at Coal Hill School in the 21st century, played a space-time scavenger hunt game with the Doctor. When Miss Chief lost, she told the Doctor Clara's whereabouts.
 
When the Doctor came to rescue Clara, she accidentally named the Doctor as a witch, and both of them were to be executed. Miss Chief brought them back to the 21st century before they could be hanged. The Doctor and Clara convinced Miss Chief to bring them back to retrieve the TARDIS and save a falsely accused woman called [[Agnes Leech]] from the dungeons, and unwittingly brought the missing cat [[Smudge]] with them. Clara convinced the mob that Hopkins was a witch and Smudge was his familiar, but the Doctor prevented them from murdering Hopkins by sneakily putting Miss Chief's time travelling marotte in his belt, forcing Miss Chief to save his life. The Doctor and Clara escaped, and returned to Coal Hill.
 
Clara told the Doctor that the Halloween Fayre, which she believed was unsuccessful, was her idea, and she intended to have funds raised in memory of Danny. However, because of the Doctor and Miss Chief bringing extinct animals and rare artefacts to the 21st century as part of Miss Chief's scavenger hunt game and her making superstitions coming true, the publicity from paranormal, wildlife and antiques experts made Clara's fundraiser at the Halloween Fayre a success, and a few months later, Clara opened the Danny Pink IT Suite, which the Doctor was also present at. ([[COMIC]]: ''[[Witch Hunt (comic story)|Witch Hunt]]'')
 
=== Abandoning young Davros ===
While looking for a bookshop, the Doctor found himself on a battlefield during the [[Thousand Year War]] on [[Skaro]], and encountered a young boy trapped in a field of [[Handmine]]s, and, during the rescue attempt, learned that the boy was [[Davros]]. When he "should have been brave enough, [and] strong enough to do something better", the Doctor fled the battlefield, unwilling to save or kill the boy who would create the Daleks. Afterwards, an older Davros, having become "very sick", asked to see the Doctor "while there [was] still time". ([[TV]]: ''[[The Doctor's Meditation]]'', ''[[The Magician's Apprentice]]'')
 
[[File:Doctor entrusts Ohila.jpg|thumb|left|The Doctor entrusts Ohila with his confession dial. ([[WC]]: ''[[Prologue (webcast)|Prologue]]'')]]
While [[Colony Sarff]] searched for him, the Doctor prepared a [[confession dial]] to be delivered to {{Gomez}}, and went to the planet [[Karn]] to met with [[Ohila]] and the [[Sisterhood of Karn]]. After hiding from Colony Sarff behind a rock, ([[TV]]: ''[[The Magician's Apprentice]]'') the Doctor was told by Ohila that he owed "that creature" nothing by partaking in a confrontation, warning him his actions would spell his end. Giving Ohila his [[confession dial]] before departing, the Doctor proclaimed that he would find a rock to meditate on in preparation for his possible destruction. ([[WC]]: ''[[Prologue (webcast)|Prologue]]'')
 
[[File:The doctor's Meditation 1.jpg|thumb|The Doctor and company prepare to dig a well. ([[TV]]: ''[[The Doctor's Meditation (TV story)|The Doctor's Meditation]]'')]]
Travelling to [[Essex]] in [[1138]] A.D., ([[TV]]: ''[[The Magician's Apprentice]]'') the Doctor gained a servant in [[Bors (The Doctor's Meditation)|Bors]] when he removed a splinter from him. After three hours of meditation in a castle, the Doctor decided he needed better drinking water, and gathered the locals to dig a [[well]]. After eleven days of finding a supply of water, and another day to construct the well, the Doctor, rather than resume his meditation, decided to make improvements to the castle, such as adding a sunroof to the throne room, ([[TV]]: ''[[The Doctor's Meditation]]'') building a first-class, child-friendly visitor centre, teaching the locals mathematics and introducing the word "Dude" to the [[12th century]]. ([[TV]]: ''[[The Magician's Apprentice]]'')
 
While additions to the throne room went underway, the Doctor had a conversation with Bors about him avoiding his meditation. Four days afterwards, the Doctor finally decided to begin mediating again before leaving the next day, and also divulged to Bors the reasons he had for being reclusive. ([[TV]]: ''[[The Doctor's Meditation]]'') For his last day at the castle, the Doctor decided to have an axe fight with Bors, and arrived on a [[tank]] playing an [[electric guitar]]. While trying to get the crowd to understand his jokes, he realised Clara and Missy had tracked him down, whereupon Bors was attacked by Colony Sarff, who demanded that the Doctor attend to Davros. Reminded of his shame at leaving the young Davros behind, the Doctor reluctantly agreed to go as a prisoner, with Clara insisting she and Missy be taken prisoner too.
 
[[File:Twelve and Davros.jpg|thumb|left|The Doctor meets with a dying Davros. ([[TV]]: ''[[The Magician's Apprentice (TV story)|The Magician's Apprentice]]'')]]
Sarff brought the trio to Davros' infirmary, where he was dying. While Clara and Missy were left in a cell block, the Doctor went to see Davros, who revealed to the Doctor that he had remembered his childhood encounter with the Doctor and revealed they were on [[Skaro]]. On a monitor, the Doctor saw that Clara and Missy had escaped their cell and been captured by the Daleks, who had also procured the TARDIS. Missy was seemingly exterminated as she tried to convince the Daleks to work with her. The Doctor begged Davros to save Clara, but Davros denied having control of the Daleks, and the Doctor was forced to watch as Clara was exterminated as well. The Daleks next, to their belief, destroyed the TARDIS. ([[TV]]: ''[[The Magician's Apprentice]]'')
 
[[File:Doctor in Davros's Chair.jpg|thumb|The Doctor, in Davros's chair, threatens the Daleks. ([[TV]]: ''[[The Witch's Familiar (TV story)|The Witch's Familiar]]'')]]
As the TARDIS was redistributed, ([[TV]]: ''[[The Witch's Familiar]]'') Davros mocked the Doctor for his compassion towards others resulting in his victory against him, ([[TV]]: ''[[The Magician's Apprentice (TV story)|The Magician's Apprentice]]'') but the Doctor, wielding a Dalek [[gunstick]], ignored Davros and forcibly removed him from his chair so he could ride in it and be safe from the Daleks' firepower. He then headed to the congregation of Daleks, and mocked them for being unable to shoot him when they tried. After his demand to know what happened to Clara was answered by the [[Supreme Dalek (Dalek City)|Supreme Dalek]] in confirmation of her demise, the Doctor was restrained by Colony Sarff and brought back to Davros's infirmary.
 
At the infirmary, the Doctor spoke with Davros, who revealed that he was able to sustain his live by siphoning off the Daleks' heartbeats through his life support system, and offered to give the Doctor control of this to commit unprovoked [[genocide]] upon the Daleks. Though tempted, the Doctor chose to be compassioned and refused to act. Davros then asked the Doctor why he left Gallifrey, and refused to be believe that the Doctor had simply left out of boredom. When Davros brought forth the Confessional dial to learn the truth, the Doctor instead took the opportunity retrieve his [[sonic sunglasses]], and also told Davros that he had saved Gallifrey, to which Davros congratulated him and, looking at the Doctor with his own eyes, was able to convince the Doctor that he was truly dying. Tearfully pleading with the Doctor to show him some understanding, the Doctor decided to give Davros his last wish: to see the sunlight with his true eyes one last time.
 
[[File:Doctor Regeneration Energy Siphoned.jpg|thumb|left|The Doctor's regenerative energy is siphoned by [[Colony Sarff]]. ([[TV]]: ''[[The Witch's Familiar]]'')]]
When Davros could no long keep them open by the time the sun rose, the Doctor proceeded to give Davros a bit of regenerative energy, but was seized by Colony Sarff and drained to regenerate Davros and all the Daleks on Skaro. He was saved when Missy killed Sarff, and revealed to Davros that he had guessed his plan all along and had tricked Davros; the regenerative energy Davros had used to renew himself and his creations had also been distributed through the sewers beneath the city, and the decaying remains of the ancient Daleks they contained had awoken and begun to emerge. While fleeing the city, the Doctor and Missy came across a Dalek that Missy claimed had killed Clara. The Doctor demanded the Dalek tell him if this was true, but the Dalek kept babbling incoherently. When it began to beg for mercy, the Doctor, suspicious, demanded it open its casing, and found that Clara had been trapped inside the Dalek, and the Doctor, furious with her, told Missy to run as he freed Clara.
 
The Doctor and Clara then entered the room housing the congregation of Daleks, and the Doctor used his sonic sunglasses to rematerialise the redistributed TARDIS and flee. As he and Clara watched the [[Dalek City]] crumble, the Doctor realised that he could teach mercy to the young Davros. ([[TV]]: ''[[The Witch's Familiar (TV story)|The Witch's Familiar]]'') Armed with the Dalek gunstick, the Doctor returned to the misty battlefield as the young Davros cried for help, ([[TV]]: ''[[The Magician's Apprentice]]'') and saved him by firing on the [[Handmine]]s. When questioned whether he was the enemy, the Doctor told Davros that friends and enemies didn't matter "so long as [there was] mercy," and then lead the boy to his home. ([[TV]]: ''[[The Witch's Familiar (TV story)|The Witch's Familiar]]'')
 
=== Continued travels with Clara ===
The Doctor and Clara continued their travels together, encountering "monsters, [and] things blowing up," and also visiting a place where people with long necks had celebrated New Years Day for two centuries. ([[TV]]: ''[[Under the Lake (TV story)|Under the Lake]]'')
 
After saving [[Zeltran Bta]] from an invader with a [[Chaos Ray]], the Doctor was informed that his activities had been advertised. Tracking the advert to [[Sterlana]], the Doctor was greeted by [[Zip Betterblast]], who introduced himself as the Doctor's self-appointed agent and had his robots give the Doctor a costume change for an interview. Cutting the interview short to deal with a [[Andromedan Feline Gigantoform]], the Doctor used his sonic sunglasses to stun the beast, and then discovered that Betterblast had used cybernetic implants to control the Feline Gigantoform. Exposing Betterblast to the public for the [[Shadow Proclamation]] to arrest him, the Doctor redoned his clothes and left with Clara to get [[coffee]]. ([[COMIC]]: ''[[Time and PR in Space (comic story)|Time and PR in Space]]'')
 
[[File:Twelve_watches_Eight.jpg|thumb|left|The Doctor and Clara watch the [[Eighth Doctor]] and [[Josie Day]]. ([[COMIC]]: ''[[A Matter of Life and Death (comic story)|A Matter of Life and Death]]'')]]
The Doctor and Clara attended an auction of the works of Lady Josephine and purchased a living [[animae particle]] portrait of her. ([[COMIC]]: ''[[Briarwood (comic story)|Briarwood]]'') Knowing that the portrait would eventually become [[Josie Day]], a companion of his [[Eighth Doctor|eighth incarnation]], the Doctor left her in 21st century [[Wales]] in [[The Doctor's cottage (The Pictures of Josephine Day)|an old cottage of his]], telling her his former self would show her the things she needed to see. The Doctor also left a to-do list in his copy of ''[[Jane Eyre]]'' for his former self to find, knowing that the adventures would help Josie build her self-confidence and see herself as far more than a painting. The Doctor and Clara later watched the Eighth Doctor and Josie as they acknowledged the events that had brought them together. ([[COMIC]]: ''[[A Matter of Life and Death (comic story)|A Matter of Life and Death]]'')
 
Arriving in an underwater base called [[the Drum]] in the year [[2119]], the Doctor found that the TARDIS was "unhappy" with her surroundings, and he and Clara then wandered around the base to find it empty with signs of struggle. Seeing two apparitions of a [[Tivolian]] and [[human]] male, they stumbled upon a spaceship marked with foreign wording, which the Doctor found untranslatable. The apparitions then chased the Doctor and Clara to a Faraday cage, containing the base's crew; [[Cass (Under the Lake)|Cass]], [[Tim Lunn]], [[Alice O'Donnell]], [[Mason Bennett]] and [[Richard Pritchard]]. Using his UNIT credentials to gain their trust, the crew explained to the Doctor that the man, [[Jonathan Moran]], had been their captain before his death, and that they had been menaced by the apparitions only at the night since discovering the ship, which lead then to believe that they were ghosts, which the Doctor debunked.
 
[[File:Capaldi Surprised.jpg|thumb|The Doctor realises that he has encountered ghosts. ([[TV]]: ''[[Under the Lake (TV story)|Under the Lake]]'')]]
As the Drum entered day mode, the Doctor learned more about the base from the crew, and further investigated the spaceship, discovering that one of the power cells was missing and [[suspended animation chamber]] was unaccountable. After reevaluating the situation caused the Doctor to conclude that the ghosts were genuine, the Drum's night mode was activated by the ghosts, and the [[Cloister Bell]] began to ring. With Prichard killed by Moran, and the ghosts trying to lure a medical team to the Drum, the Doctor ordered the base be locked under quarantine and encouraged the surviving crew to help him capture the ghosts.
 
Trapping the ghosts in the Faraday cage, the Doctor found they were repeating coordinates to the flooded town's church, and that the ghosts had been artificial created to act as a homing beacon. After Bennett retrieved the ship's suspended animation chamber, the Doctor found that the coordinates had been the symbols within the spaceship, and decided to go back in time to before the town's flooding to find the truth of the matter. As the Doctor, Clara and the crew made their way to the TARDIS, the ghosts began flooding water into the Drum, resulting in emergency doors coming down and splitting the group in half. Clara was trapped in the base with Cass and Lunn, while the Doctor set off in the TARDIS with O'Donnell and Bennett. ([[TV]]: ''[[Under the Lake (TV story)|Under the Lake]]'')
 
[[File:Platform BtF.jpg|thumb|left|The Doctor and O'Donnell arrive at [[Краснодар]]. ([[TV]]: ''[[Before the Flood (TV story)|Before the Flood]]'')]]
Arriving in [[1980]], the Doctor, O'Donnell and Bennett encountered the Tivolian, [[Albar Prentis]], while he was alive, using the spaceship, which had yet to have the wording inscribed, as a hearse to transport a dead warlord known as the [[Fisher King]]. Wanting to destroy the signal, the Doctor demanded Prentis hand over the device broadcasting, but Prentis was oblivious to what the Doctor was talking about.
 
Contacting Clara, the Doctor found that a ghost of himself had appeared in 2119, mouthing the names of the dead and those yet to die, with Clara second after O'Donnell. The Doctor was shaken at the prospect of him dying, but, despite Clara's urging to change time, he insisted he had to die. The Doctor's ghost then entered the Drum and released the other ghosts, forcing Clara, Cass and Lunn back to the Faraday Cage, where the phone signal was cut off. Before they left, however, the Doctor was able to get a look at his ghost and see him change his message.
 
Realising O'Donnell was going to die, the Doctor and Bennett tried to persuade her to stay in the TARDIS, but she refused. Returning to the ship, the trio found Prentis dead, the writing written and themselves being hunted by the Fisher King. Persuade into a building, O'Donnell was separated from the group and killed by the Fisher King, fulfilling the Ghost Doctor's prophecy. The Doctor and Bennett then tried to go back to the future to save Clara from being killed, but the TARDIS instead sent them back in time by thirty minutes, where the Doctor had to force Bennett from interfering in Prentis and O'Donnell's deaths.
 
Sending Bennett back to the TARDIS, the Doctor set one of the ship's power cells to destroy the dam of the town. Confronting the Fisher King, the Doctor was informed that the ghosts were signalling to the Fisher King's armada to rescue him and enslave the Earth. Just as he was about to be shot, the Doctor lied about erasing the writing from the ship, provoking the Fisher King to return to the ship, just as the damn well apart and flooded the town. Before the flood hit the church, the Doctor got into the Fisher King's stasis chamber, protecting him as the Fisher King drowned in the flood. ([[TV]]: ''[[Before the Flood (TV story)|Before the Flood]]'')
 
[[File:Before the Flood.jpg|thumb|The Doctor's hologram ghost. ([[TV]]: ''[[Before the Flood]]'')]]
In 2119, the pod was recovered by Bennett and brought upon the Drum to be examined by the past Doctor. ([[TV]]: ''[[Under the Lake]]'') Using his sonic sunglasses to connect with the Drum's [[Wi-Fi]], the Doctor created a hologram of himself as a ghost "with a soupçon of artificial intelligence, and a few pre-recorded phrases thrown in," ([[TV]]: ''[[Before the Flood]]'') which appeared before Clara, Lunn and Cass almost immediately after the past Doctor left the Drum with Bennett and O'Donnell. ([[TV]]: ''[[Under the Lake]]'')
 
Using the hologram as an avatar, the Doctor gave Clara the list he had heard her give him from the ghost, and released the other ghosts from the Faraday cage, telling his past self via Clara's phone that "the chamber will open tonight." Conversing with other ghosts, the Doctor set them on Lunn, knowing they wouldn't kill him, to set a trap for Clara and Cass in the cantina.
 
When the chamber opened, the Doctor used his ghost hologram to lure the other ghosts to the Faraday cage with the "call of the Fisher King." Erasing the writing from their minds, the Doctor revealed to Clara, Cass and Lunn that his ghost was just a projection, and told them and Bennett that UNIT would dispose of the ghosts by removing the Faraday cage from Earth's orbit. As he and Clara set off in the TARDIS, the Doctor told her he only knew what to make the fake ghost say because she told him what it was saying, calling it a bootstrap paradox. ([[TV]]: ''[[Before the Flood (TV story)|Before the Flood]]'')
 
The Doctor dropped Clara off on the planet [[Karaoke (planet)|Karaoke]] while he stayed inside to do repairs on the TARDIS. When asked if he had any musical interest, the Doctor recalled the time that his first four incarnations had attempted to form a band. It had fallen apart due to creative differences. Clara, bemused by this thought, exited the ship onto the planet before the Doctor could warn her that he would be momentarily shutting the TARDIS down, leaving the [[translation circuit]]s off. ([[COMIC]]: ''[[Day of the Tune (comic story)|Day of the Tune]]'') As Clara did not hear his warning, she began singing on the stage, where the TARDIS translation began to fail as she could no longer read the lyrics on screen. No longer able to read the words at hand, Clara began to mumble gibberish. By coincidence, part of what she mumbled was offensive in [[Karaeokean]], and she and the Doctor were locked in jail on the planet. ([[COMIC]]: ''[[The Meddling of Clara's Song (comic story)|The Meddling of Clara's Song]]'')

The two were given a chance of survival by forced entry into ''[[The Battle of the Bands Beyond the Stars]]'', a musical competition. If their performance was deemed poor, they would be killed. As the two nervously prepared for this competition, they were passed by a band formed of what appeared to be [[Headless Monks]]. However, these robed figures soon removed their hoods, revealing themselves to be various incarnations of [[the Master]] -- including their lead singer, {{Gomez}}. ([[COMIC]]: ''[[The Abominable Showmen (comic story)|The Abominable Showmen]]'')
 
[[File:The_Master_begs_the_Doctor_to_hear_her_plans.jpg|thumb|Missy begs the Doctor to ask about her plans. ([[COMIC]]: ''[[The Five Masters]]'')]]
Missy approached the Doctor, expecting him to begin asking about her plans and trying to stop her. The Doctor, seemingly uninterested, refused to intervene or ask questions of their scheme. After much prying from Missy, the Doctor correctly predicted that Missy planned to use hypnosis to take over the minds of the viewers watching the program. As Missy and the Masters prepared to do their performance, the Doctor chose not to intervene, much to the dismay of Clara. Instead, the pair watched as the five Masters began to fight over [[Missy's device]], each wanting to control the universe without the others. The five were soon disqualified after the failed to do their performance. The Doctor noted that he knew it was impossible for the many egos of the Master to work together as a team, in the same way that it had not worked out when he had tried it himself. The pair prepared for their performance, the Doctor confident that he could pull it off. ([[COMIC]]: ''[[The Five Masters]]'')

As the Doctor was about to perform, Clara disconnected some power cables, allowing them to escape the stage and get back to the TARDIS. Clara wondered how they would be able to stop the show, but the Doctor told her that after the installment they had just ruined, the show was cancelled due to all-time lowest viewing figures. They set off together to get chips. ([[COMIC]]: ''[[One! Two! Three! Four! To Doomsday (comic story)|One! Two! Three! Four! To Doomsday]]'')
 
After saving the [[Velosian]]s from being attacked by "four and a bit battle fleets" and rescuing Clara from being killed by a [[Love Sprite]] from the [[Spider Mines]], the Doctor and Clara landed on Earth, where they were promptly captured by Vikings and taken to their village, two days' [[longboat]] journey from the TARDIS. When a race called the [[Mire]] attacked the village, killing all of the warriors, a girl called [[Ashildr]] declared war between the village and ten of the Mire.
 
After failing to train the farmers in the village to fight, the Doctor realised the village farmed [[electric eel]]s, enabling him to formulate a plan to defeat the Mire. When the Mire arrived, the Doctor and the farmers distracted them with a party in a barn, while the other villagers used the eels to electrocute four of the Mire and remove their armour and weapons. Seizing the opportunity, the Doctor gave one of the helmets to Ashildr, who used it to feed the image of a dragon into the technology of the Mire's helmets, scaring them off, when the dragon was actually nothing more than a puppet. The Doctor revealed to the Mire leader, who posed as the Viking god [[Odin (The Girl Who Died)|Odin]], that Clara had filmed them being scared away by the villagers and threatened him and to leave lest the video be release to the [[Galactic Hub]] and ruin the Mire's reputation. Odin and the Mire promptly left, but the celebrations ended when it was discovered Ashildr had died of heart failure as a result of using the Mire helmet.
 
[[File:TwelvesFace.jpg|thumb|The Doctor remembers where he has seen his face before. ([[TV]]: ''[[The Girl Who Died (TV story)|The Girl Who Died]]'')]]
The Doctor moped in a barn, regretting being unable to save Ashildr. However, after voicing his pain to Clara (including stating in emotional terms how he would react if he ever lost Clara), he realised that he shared the face of [[Lobus Caecilius]], whom he had [[The Fires of Pompeii (TV story)|saved from a fixed point in time]] during his [[Tenth Doctor|tenth incarnation]], and concluded that his face was a reminder to himself that he should always save people, even damning anyone who thought against the act to hell. Using a [[Mire medical kit|medical chip]] from the Mire helmet, the Doctor revived Ashildr, and left her a second chip for whoever she wanted. Heading back to the TARDIS, the Doctor, now reflecting poorly on his actions, told Clara that the chip would have given Ashildr immortality, and then realised that he had made her a hybrid. ([[TV]]: ''[[The Girl Who Died (TV story)|The Girl Who Died]]'')
 
=== Solo adventures ===
{{section stub|Info from ''[[Helana and the Beast (short story)|Helana and the Beast]]'' needs to be added}}
Sometime after leaving Scandinavia, Clara asked the Doctor to help her student [[Evie Hubbard]] with an assignment: an imaginary interview with [[Winston Churchill]]. Not realising that Clara simply wanted the Doctor to tell Evie about Winston, he instead took her back to [[World War II]] to talk with him.  [[Evie Hubbard|Evie]]  subsequently got an A on her assignment, though Clara criticised the Doctor for having "basically cheated." ([[TV]]: ''[[The Woman Who Lived]]'')
 
While Clara was taking her Year Seven class to their [[tae kwon do]] lessons, ([[TV]]: ''[[The Woman Who Lived (TV story)|The Woman Who Lived]]'') the Doctor decided to check on Ashildr's immortal life. (TV: ''[[Face the Raven (TV story)|Face the Raven]]'') One of the acts he observed was Ashildr founding a colony of [[leper]]s. The Doctor didn't make contact with Ashildr, not realizing she was waiting for him to return. (TV: ''[[The Woman Who Lived (TV story)|The Woman Who Lived]]'')
 
Unable to go to the [[Castles of Trutalia]] due to his TARDIS being clamped by an out-of-date [[Ministry of Time robot]], the Doctor went to [[Garage 10]] to get the parts needed to fix the robot. En route, he befriended a wannabe mechanic named [[Athena (The Ministry of Time)|Athena]], and, working together, the pair learned that the owner of Garage 10 was stripping his customers of their identity to recruit them and sell their memories. Undoing the owner's actions, and getting him arrested by the [[Judoon]], the Doctor parted ways with Athena to update the Ministry of Time robot into having its own sense of adventure. ([[COMIC]]: ''[[The Ministry of Time (comic story)|The Ministry of Time]]'')
 
Getting trapped in a room of metal on fire, the Doctor sent his sonic sunglasses down to Earth, where they were found by a father out walking with his son. When the father put them on, they activated the [[Telepathic Emergency Beacon]], allowing the Doctor to take control of his body and pilot the TARDIS to free himself. As a reward, the Doctor allowed the father and son a free trip, which the father used to pick up his wife, who had apparently disappeared months earlier. ([[PROSE]]: ''[[My Dad, The Doctor (short story)|My Dad, The Doctor]]'')
 
The Doctor found a giant robot and kaiju fighting in a [[Japanese]] city, and that [[UNIT]] soldiers led by [[Colonel]] [[Ishiguro]] were preparing to attack them. Persuading Ishiguro to halt the attack, the Doctor discovered that they were the result of a stolen [[Kaznak Simu-system]] being used by [[Professor]] [[Nakatomi]] for his video game company. Overriding the data core with his own mind, the Doctor ended the fighting before UNIT needed the intervene, and went of with Ishiguro for some [[noodle]]s. ([[COMIC]]: ''[[Big in Japan (comic story)|Big in Japan]]'')
 
After spending weeks following exoplanetary energy on his [[curioscanner]] across the galaxy, the Doctor traced the [[Eyes of Hades]] to [[1651]] [[England]], where he found a highwayman called "the Knightmare" robbing the carriage holding the artifact. The Doctor's intervention resulted in the carriage escaping before either of them could get the Eyes, and the Knightmare revealed herself to be Ashildr, who was now addressing herself as "Me" after losing most of her childhood memories; as Ashildr explained human memories are finite, which doesn't help with an immortal life. At "Lady Me's" mansion, Ashildr told the Doctor of her exploits, and begged him to her with him in the TARDIS, but he refused. Instead, the two teamed up to steal the Eyes of Hades from [[Lucie Fanshawe]] by breaking into her mansion.
 
[[File:Twelve Knightmare.jpg|thumb|left|The Doctor and the Knightmare stealing the [[Eyes of Hades]]. ([[TV]]: ''[[The Woman Who Lived]]'')]]
The Doctor then found that Ashildr had an ally in [[Leandro]], who owned the Eyes of Hades and needed a death to activate it to open a portal for him and Ashildr to escape Earth in. Upon learning the highwayman [[Sam Swift]] was to be executed, Ashildr and Leandro set off to use his death to activate the artefact. While the Doctor tried to call off Swift's execution,  Ashildr forcibly attached the Eyes of Hades to Swift, opening the portal. Leandro then revealed that he had only used Ashildr to get the portal open and allow his people to invade, and the [[Leonian]] ships began attacking the peasants. Realising her mistake, Ashildr used the second Mire chip to revive Swift, closing the portal and ending the attack. For his failure, Leandro was incinerated by his people. In the aftermath, Ashildr accepted her inability to travel with the Doctor and told him she would look out for other people he left behind, and they parted on relatively good terms.
 
When the Doctor picked up Clara for more adventures, she presented him with a [[selfie]] from [[Evie Hubbard]], a student he had helped with history homework, and the Doctor was shocked to see Ashildr in the background of the photo. Shaking it off, he and Clara took off for "somewhere magical." ([[TV]]: ''[[The Woman Who Lived (TV story)|The Woman Who Lived]]'') The Doctor kept surveillance on Ashildr, but lost track of her in the early [[1800s]]. ([[TV]]: ''[[Face the Raven (TV story)|Face the Raven]]'')
 
=== Final adventures with Clara ===
Receiving a call from Osgood about the "Nightmare Scenario", the Doctor discovered that the ceasefire between the [[human]]s and [[Zygon]]s had been breaking down, and tried to confront the [[Zygon High Command]] about it, only for them to be kidnapped by Zygon rebels, just as [[Kate Stewart]] phoned him to inform the Doctor of Osgood's kidnapping. Meeting up with Clara and Kate at Zygon High Command base at [[Drakeman Junior School]], the Doctor communicated with the [[control polyp]] and witnessed the rebels execute the Zygon High Command. Sharing thoughts with Kate, Clara and [[Jac (The Magician's Apprentice)|Jac]], the Doctor sent Kate to investigate Zygon activity in the [[New Mexico]] town [[Truth or Consequences (town)|Truth or Consequences]], and left Clara and Jac in charge of defending [[England]] while he took [[Boat One]] to the Zygon settlement in [[Turmezistan]] to rescue Osgood.
 
[[File:Osgood confuses Twelve.jpg|thumb|The Doctor questions Osgood on her identity. ([[TV]]: ''[[The Zygon Invasion (TV story)|The Zygon Invasion]]'')]]
The Doctor and [[Colonel]] [[Walsh]] led a platoon of UNIT soldiers to retrieve Osgood from the Zygon base before it was destroyed in an air strike, but [[Johnny Hitchley|the leading soldier]] fell for the Zygons' deceptions and lead the platoon to their deaths in an ambush. As Walsh left to observe the settlement get destroyed, the Doctor found Osgood and managed to capture [[Zygon (The Zygon Invasion)|a Zygon]]. Aboard Boat One, the Zygon informed the Doctor that the Zygon invasion of Earth had already taken place. As the plane returned to the United Kingdom, "[[Bonnie (The Zygon Invasion)|Clara]]" phoned the Doctor, and, claiming that the real Clara and Kate had been killed and replaced, fired a [[rocket launcher]] from the ground at Boat One. ([[TV]]: ''[[The Zygon Invasion (TV story)|The Zygon Invasion]]'') The Zygon missed her first shot, which gave the Doctor and Osgood enough time to parachute out of the plane before she fired a successful shot. They landed safety and received a text from Clara's phone, confirming that she was alive and fighting the Zygon in her form. Calling the Zygon, who had named herself "[[Bonnie (The Zygon Invasion)|Bonnie]]", the Doctor retrieved a message from Bonnie's winking eye (controlled by Clara inside the pod) that confirmed her location, and, persuade by policeman he thought were Zygons, commandeered a van to get him and Osgood back to London.
 
They drove to a south London shopping centre where a Zygon had been forced to normalise himself by Bonnie and, despite the Doctor pleading him not too, committed [[suicide]] because he didn't want to be a part of the Zygon rebellion. Kate and two UNIT soldiers then turned up, and told the Doctor where to find Clara and the Zygon rebel base. Arriving at the Zygon stronghold, the UNIT soldiers revealed themselves to be Zygons and Kate contacted Bonnie, who had taken Clara with her to the [[Black Archive]] to activate the [[Osgood Box]]. However, Bonnie then revealed that the Doctor had put two Osgood Boxes in place with safeguards beyond safeguards in to keep the human-Zygon ceasefire, and demanded the Doctor be brought to her. Kate, however, revealed herself to be the genuine Kate, killed the Zygon soldiers and destroyed the communicator. 
 
[[File:TwelveWarMemories.jpg|thumb|left|The Doctor invokes his memories of the Time War in a bid to make Bonnie see sense. ([[TV]]: ''[[The Zygon Inversion (TV story)|The Zygon Inversion]]'')]]
Arriving at the Black Archive, Bonnie and Kate both threatened to use the Osgood boxes, but the Doctor used his memories and feelings of the [[Last Great Time War|Time War]] to persuade them that they could end the conflict in a more humane way. Moved by his speech, Kate decided not to use the boxes, and Bonnie realized they're empty; the Doctor explained Bonnie was able to know that because she started thinking like him. To keep the boxes' secret safe, the Doctor erased the memories of Kate and Bonnie's Zygon guards.
 
As the Doctor and Clara prepared to leave, the Doctor invited Osgood to join him in his travels, but she denied as she had the boxes to look after. Both she and Bonnie, who was now using Osgood's form, continued the task of protecting the Osgood Boxes and maintaining the human-Zygon relations together. Stating they were a credit to their species, the Doctor told them he was a big fan of [[Petronella Osgood|Osgood]], just like she was a fan of him. ([[TV]]: ''[[The Zygon Inversion (TV story)|The Zygon Inversion]]'')
 
[[File:TwelveCameras.jpg|thumb|right|The Doctor explains that the "cameras" on ''[[Le Verrier]]'' are actually the [[sleep dust]]. ([[TV]]: ''[[Sleep No More (TV story)|Sleep No More]]'')]]
The Doctor and Clara landed on the space station ''[[Le Verrier]]'' in the [[38th century]], and joined a rescue crew that were looking for the station's crew. Attacked by [[Sandman (Sleep No More)|Sandmen]], the group ran into a laboratory housing [[Morpheus pod]]s and, after rescuing Clara from one, found Professor [[Gagan Rassmussen]] hiding in a pod. After questioning Rassmussen on his pods, the Doctor concluded that the Sandmen were made up of [[sleep dust]], and a direct result from use of the pods. As they made their way to destroy the pods, the station's [[gravity shield]]s failed, Rassmussen was killed by a Sandman, and the Doctor, Clara and Chief [[Jagganth Daiki-Nagata|Nagata]] became separated from the group after the Doctor rebooted the gravity shield.
 
Revaluating the situation, the Doctor hacked in to what he believed to be the rescue crew's helmet cams to review the footage, only for Nagata to reveal that none of them were wearing cameras. The Doctor then realised that the sleep dust in the air was being used as cameras to store images of the rescue mission, and that Rassmussen was behind the entire thing. Going to the crew's rescue ship, the Doctor, Clara and Nagata found Rassmussen had plans to spread the Sandmen to other planets. Surviving Rassmussen's attempt to kill them with his [[Patient Zero (Sleep No More)|Patient Zero]], Nagata killed Rassmussen, and the trio fled the station in the TARDIS, intending to destroy all Morpheus machines to prevent any more Sandman conversions. The Doctor, however, was confounded by the loose ends and how choreographed the event had been. ([[TV]]: ''[[Sleep No More (TV story)|Sleep No More]]'')
 
After thwarting a run-in with the warlord Lucifer van Volk, who accused him of magnetizing his mercenary army at some point in his future, the Doctor returned to 2015 to find that Clara had taken a leave of absence from Coal Hill and traveled to Ravenscaur, a Scottish private school, to investigate the disappearance of her friend Christel. While Clara took over Christel's vacated job as an English teacher, the Doctor went undercover in the local town, where he found the townspeople were a disguised race of aliens plotting against humanity. Deducing that Ravenscaur was the centre of the plan, he instructed Clara to remain undercover at the school while he worked out what they were dealing with. During this time, the Doctor displayed a bizarre sense of humour by adopting a stuffed swordfish that he had used to defend himself during a brawl at a pub, naming the fish Sonny and claiming it as his newest "companion", much to Clara's annoyance.
 
Under the suspicion that the [[Sea Devils]] were behind the plan, the Doctor explored the catacombs of Ravenscaur to confirm his suspicions and ended up rescuing Clara and two students, Lucy and Jack, from the Sea Devils. The group returned to the school only to be captured by the headmaster Mrs Mariner, who revealed she and many of the school's students and facility were disguised Sea Devils, as well as the visiting Prime Minister Daniel Claremont. They were plotting to use humanity's global warming against them to create a perfect environment for their race. While Claremont was giving a televised press conference at the school, the Doctor set off the school's sprinklers, causing the disguised Sea Devils to revert to their normal forms. Mariner, however, commanded all Sea Devil bases to rise, revealing they had the machinery ready to wipe out humanity.
 
The Doctor equipped Clara, Jack and Lucy with neural enhancers, allowing them to use their telekinetic power to combat and escape the Sea Devils. Ordering Clara to evacuate the school, he navigated to the rooftops to confront Mariner, but was too late to prevent her from ordering the troops to rise. The Doctor altered the trajectory of their devastation pulse so that their weapons would attack Raven's Isle rather than the mainland. As the school and Sea Devils were destroyed, Clara, still equipped with her neural enhancer, flew in and rescued the Doctor from the destruction. As the two left in the TARDIS, the Doctor asked Clara if she wanted to go home, but she replied that being with him was home.

The Doctor and Clara tracked mysterious energy fluctuations and disappearances to a comic store in London, where the Doctor was sucked into a comic book. Clara found that the missing people had also been pulled into comic books, and that the Boneless were the culprits. From within the comic, the Doctor told Clara to use the TARDIS' telepathic circuits to create a spatical and temporal flux. Teaming up with Natalie, a girl who was also trapped in his comic, he encouraged all the trapped people to use their love of comics to telepathically break free, imploding the Boneless back to their dimension and returning the victims to the real world.

=== The coming of the hybrid ===
After escaping a marriage to a sentient plant on the "second most beautiful garden in all of time and space," the Doctor was phoned by [[Rigsy]], who had lost his memory of the previous day and woken up with a [[chronolock]] that was counting down to his death. Investigating, the Doctor, Clara and Rigsy found themselves in the [[Trap Street, London|trap street]], where a society of aliens were seeking asylum under the government of Ashildr, known in the street as "[[Mayor]] Me". Rigsy had apparently murdered one of the residents, a [[Janus (species)|Janus]] named [[Anah]], and had been given [[retcon]] per the street's protocol, but returned home to allow him to spent time with his loved ones before the [[Quantum Shade]] came to kill him for the crime.
 
When Ashildr informed the Doctor that she could remove the chronolock if he convinced the trap street residence of Rigsy's innocence, the Doctor learned from [[Kabel]] that Rigsy had asked Ashildr to call the Doctor when he was found with the body, revealing that Ashildr knew of the Doctor and Risgy's acquaintanceship. Going to see the victim's daughter, [[Anahson]], the Doctor realised that the entire thing had been a trap to lure him to the trap street. Running to see the body, the Doctor discovered that Anah was alive in a [[stasis pod]], and the only way to release her was to unlock the pod with his [[TARDIS key]]. Unlocking the stasis pod, the Doctor had his arm clamped with a [[teleport bracelet]], just as Ashildr arrived to retrieve the Doctor's [[confession dial]].

Just as the chronolock countdown ended, Clara revealed that she had taken Rigsy's death sentence, and Ashildr explained that the entire thing had been a hoax to entice the Doctor, as she had been threatened to entrap the Doctor to ensure the street's safety. Rigsy would have had the chronolock removed before its countdown ended, but since Clara took it, Ashildr fell out of the contract she had established, sealing Clara's fate. In anger, the Doctor threatened to end the asylum unless she saved Clara, but Clara made the Doctor promise not to seek revenge before she faced her death, with the Doctor watching her die from afar. Ashildr apologised for the harm she had done, but the Doctor, honouring his promise to Clara, warned her to keep out of his way. The teleport bracelet then activated, teleporting the Doctor away to its destination. ([[TV]]: ''[[Face the Raven (TV story)|Face the Raven]]'')
 
[[File:Doctor emerges from portal.jpg|thumb|The Doctor returns to [[Gallifrey]]. ([[TV]]: ''[[Heaven Sent (TV story)|Heaven Sent]]'')]]
In a cycle that went on for 4.5 billion years, ([[TV]]: ''[[Hell Bent]]'') the Doctor arrived in a teleporter at the top of tower inside his [[confession dial]], and was pursued by the [[Veil (Heaven Sent)|Veil]], a creature taken from his childhood nightmares, until he fed it confessions. During this time he frequently retreated to a mental "storm room" - a recreation of the TARDIS - where he spoke to a mental recreation of Clara. At the end of each cycle, the Doctor reached a wall of solid [[azbantium]] and, inspired by the [[Brothers Grimm]] story of the shepherd's boy, punched at the wall until the Veil fatally burned him. Too badly injured to regenerate, the Doctor dragged himself back to the top of the tower and burn up his body to provide the energy needed to load a copy of himself at the moment of his arrival from the teleporter's hard drive, continuing the cycle until he finally broke through the wall. With the Veil collapsing in on itself, the Doctor arrived on [[Gallifrey]] and told [[Gallifreyan boy|a nearby boy]] to inform "someone important" in the [[Capitol]] of his arrival. ([[TV]]: ''[[Heaven Sent]]'')
 
[[File:Twelve confronts President.jpg|thumb|left|The Doctor confronts Rassilon. ([[TV]]: ''[[Hell Bent (TV story)|Hell Bent]]'')]]
The Doctor made his way to the [[Drylands]], where he silently waited in [[Barn (The Day of the Doctor)|his old barn hideaway]] for [[Rassilon]] to face him, turning away the military and [[High Council]] members sent to speak to him, until Rassilon finally came to explain himself, to which the Doctor told him  "get off [his] planet." Deeming any witness in the Drylands to be unimportant, Rassilon ordered the Doctor's execution, but the firing squad, having served with [[War Doctor|the Doctor of War]] during the [[Last Great Time War]], sided against him. When [[the General]] defected, Rassilon surrendered and the Doctor, assuming Rassilon's title of [[Lord President]], banished Rassilon from Gallifrey, which had been moved to the [[end of the universe]] for protection, blaming him for the horrors of the Time War, to be followed by the High Council.
 
Going down to the [[Cloisters]], the Doctor met with [[Ohila]], who explained that Rassilon was searching for information on [[the Hybrid]]. Meeting with the General and the [[Sisterhood of Karn]] in the council chamber, the Doctor informed them that he could protect them from the Hybrid, but he needed Clara Oswald's help to do so. The Doctor and the General went to [[Extraction chamber 7]] to use an [[extraction chamber]] to retrieve Clara from before her death in the [[Trap Street, London|trap street]], in doing so freezing her bodily functions in time. Under pressure to explain himself, the Doctor swiped the General's [[sidearm]] and, holding the unarmed chamber staff at gunpoint, took a [[neural block]] calibrated for humans and shot the General to cause a distraction and escape with Clara.
 
Making their way through the Cloisters, the Doctor and Clara encountered the [[Cloister Wraith]]s, and an imprisoned [[Dalek (Hell Bent)|Dalek]], [[Cyberman (Hell Bent)|Cyberman]] and [[Weeping Angel (Hell Bent)|flock of Weeping Angels]], until the Doctor found a secret passage near lift shaft 7, and told Clara how he had originally found the passage as a boy, and also tried to avoid talking about his imprisonment in his confession dial, but had got around to telling Clara by the time the newly regenerated General and Ohila arrived. As Clara distracted them, the Doctor escaped through the secret passage into the workshop below the Cloisters, and stole [[TARDIS (Hell Bent)|a TARDIS]] to retrieve Clara and flee from Gallifrey after a final talk with Ohila.
 
[[File:Claras memories.jpg|thumb|The Doctor faces the prospect of wiping Clara's memories. ([[TV]]: ''[[Hell Bent (TV story)|Hell Bent]]'')]]
With Clara still frozen, the Doctor took her to the last minutes of the universe, believing that time would heal there and Clara would become alive again. With Clara still frozen, a knock sounded on the TARDIS doors and the Doctor found it was Ashildr, still alive at the end of the universe. The Doctor and Ashildr shared theories on the Hybrid; the Doctor believing it to be Ashildr, while she believed the Hybrid to either be the Doctor himself, or the combined forces of the Doctor and Clara. The Doctor, denying Ashildr's claims, told her that he planned to erase Clara's memory of him to protect her from the Time Lords, but Clara had spied on their conversation and reversed the polarity of the neural block with the sonic sunglasses. After learning of what Clara did, the Doctor still decided to use the device, only for it to backfire on him, causing him to loose his memories of Clara and collapse.
 
[[File:Twelve Clara diner.jpg|thumb|left|The Doctor tells his story to Clara in the diner. ([[TV]]: ''[[Hell Bent (TV story)|Hell Bent]]'')]]
The Doctor eventually awoke in the [[Nevada]] desert, where [[Man (Hell Bent)|a man]] told him that Clara had asked him to look after the Doctor. Having forgotten Clara's face, but still having vague impressions of his time with her, the Doctor made his way to a diner in the desert, where he encountered a waitress. The Doctor told the waitress his story while playing [[Clara (song)|a song he composed for Clara]]. After his story ended, the waitress exited through a door, and the diner dematerialised, revealing to the Doctor that it had been the stolen TARDIS. Now outside, the Doctor found his own TARDIS, with a mural dedicated to Clara on it, whom the Doctor recognised as the waitress. Receiving a new sonic screwdriver from the TARDIS, a replacement for the velvet jacket, and a final message of encouragement from Clara scrawled on one of the TARDIS' blackboards, the Doctor took off for new adventures on his own, with the mural unraveling as he dematerialized. ([[TV]]: ''[[Hell Bent (TV story)|Hell Bent]]'')
 
=== Lone travels ===
The Doctor arrived in an empty school during [[2115]] Christmas time and met [[Ross McNamara]], who was supposedly being chased by a ghost. Investigating, the Doctor found that a [[Helestician]] spaceship was hidden in the cellars, and that it had sent Ross forward in time from [[2015]] and that the ghost was an echo of Ross created by the time travel. After blowing up the school to free the spaceship, the Doctor returned Ross home. ([[PROSE]]: ''[[Haunted (short story)|Haunted]]'')
 
The Doctor visited the planet [[Lahn]] to travel the Spice Route of Shalabar Stone. However,  his party was ambushed by alien scavengers led by the Lord [[Boabdil]], who kidnapped the Doctor's fellow traveller, [[Estrella]], sentencing her to be executed the following day by a monster. The Doctor gatecrashed the execution and disorientating the monster, freeing Estrella. Chased into the city, Estrella bought a flying carpet, allowing her and the Doctor to escape their pursuers. ([[COMIC]]: ''[[The Spice Route (comic story)|The Spice Route]]'')
 
The Doctor received a phonecall from [[Osgood (The Day of the Doctor)|Osgood]], telling him to come [[London]] to deal with a [[K2|"big problem"]]. UNIT had recreated the [[K1]] robot under orders from the British government. It escaped and went on a rampage in downtown London. After picking Osgood up with his TARDIS, the Doctor materialized over the [[River Thames]]; where K2 was tearing apart the [[London Eye]]. The Doctor used his sonic screwdriver's red setting to dissemble the robot, saving the city of London once again. ([[COMIC]]: ''[[Robo Rampage (comic story)|Robo Rampage]]'')
 
[[File:Ghosts_of_the_Seas_cliffhanger.jpg|thumb|left|The Doctor is threatened by [[Hendrick Vanderdecken (robot)|Hendrick Vanderdecken]]. ([[COMIC]]: ''[[Ghosts of the Seas (comic story)|Ghosts of the Seas]]'')]]
The Doctor found that the [[Flying Dutchman]] was making appearances throughout history, and tracked it through time. On a sighting on the seas in [[1881]] [[Australia]], he was joined by [[George (Ghosts of the Seas)|Prince George]] and [[Thorpe (Ghosts of the Seas)|Captain Thorpe]] after they wandered into the TARDIS. The Doctor deduced mathematically that the ship would appear during the [[Battle of Trafalgar]], and he, George and Thorpe managed to board it only to be confronted by robots claiming to be the ship's crew. After George meddled with the ship's machinery, the robots lost their memory. The Doctor found that the robots had crashed their time ship into the Dutchman and that had caused them to believe they were the crew. The Doctor repaired the ship to send the robots home, and also prepared to return George and Thorpe to their own time as well. ([[COMIC]]: ''[[Ghosts of the Seas (comic story)|Ghosts of the Seas]]'')
 
Attending [[UK Book Festival|a book festival]], the Doctor learnt of a book series called ''[[Fearsome Frights]]'' by an author called [[Charles Abbott]]. A girl called [[Eliza Jones|Eliza]] told him that the protagonist of the book shared the name of her brother [[Sammy Jones|Sammy]], who had disappeared after meeting Abbott at a signing. The Doctor and Eliza tracked the book in the TARDIS, and the Doctor deduced that Abbott was a disguised alien who used a pen made of [[Incredulitas 4]] that could transport matter. They arrived on the planet [[Antagonista]], the setting of the book, and rescued Sammy from [[zombie]]s. Abbott arrived and tried to attack the group with his pen, but the Doctor used his sonic screwdriver to counter the attack and trap Abbott in [[The writer's block|a stasis jail cell in space]]. Dubbing the cell the "writer's block", the Doctor returned Eliza and Sammy home. ([[COMIC]]: ''[[Shock Horror (comic story)|Shock Horror]]'')
 
The Doctor detected temporal tsunamis in the time vortex, and realized something was wrong with time and that he needed to get to Gallifrey. As Gallifrey was blocked by a transduction barrier and he was unable to contact the High Council, he traveled to Karn to persuade Ohila to let him use the Sisterhood of Karn's door to the Capitol. Ohila was reluctant, but when Karn was suddenly attacked by Cybermen, she let him through. The Doctor rushed into the Capitol only to find Rassilon. Rassilon revealed to the Doctor that after his overthrow and exile, he met with a league of Cybermen and decided to work with them to create a new Time Lord-Cyberman empire. The Doctor was then rescued by a group of Time Lord soldiers led by the General, who requested the Doctor's assistance in helping them combat the threat. When he experienced pain spasms, the Doctor realized that Rassilon's corruption of the Eye of Harmony was rewriting his own history to ensure his previous incarnations were defeated by the Cybermen on their adventures.
 
The Cybermen betrayed Rassilon and began harvesting his and the Doctor's regeneration energy to fuel the reworking of history, allowing the rise of the age of Cyberiad. Having realized his mistake, Rassilon telepathically contacted the Doctor inside the Cyberiad and the two teamed up to send their regeneration energy backwards through the Eye of Harmony, repairing the alterations made to the Doctor's timeline and the universe and destroying the Cyberiad. The Doctor's previous incarnations and everybody else lost their memories of the incident, with only the Twelfth Doctor remembering. Back in his TARDIS alone, he openly wondered if Rassilon remembered as well. ([[COMIC]]: ''[[Supremacy of the Cybermen (comic story)|Supremacy of the Cybermen]]'')
 
[[File:Twelve saves Eskdale Hall.jpg|thumb|left|The Doctor saves [[Eskdale Hall]] from crashing into the surface of [[New Belgravia]]. ([[COMIC]]: ''[[Sky Manor (comic story)|Sky Manor]]'')]]
The Doctor then visited what he thought was the English countryside for a breath of fresh air. After almost walking off the side of a floating island, the Doctor discovered that he was on [[New Belgravia]]. He met the owner of the island, [[Lord]] [[Eskdale]], who was also the owner of the planet. Eskdale asked the Doctor to help him find his daughter [[Charlotte Eskdale|Charlotte]]. Shortly after the Doctor accepted the offer, the floating island began fall towards the ground. The Doctor found Charlotte in the engine room of the island, who had hid there after seeing her father discriminate against the [[New Belgravian|planet's natives]]. She accidentally turned off the engines of the island. Eskdale apologised to his daughter, leading to her letting the Doctor into the engine room. He moved the island back into the sky, saving countless lives. ([[COMIC]]: ''[[Sky Manor (comic story)|Sky Manor]]'')
 
[[File:12 & Dogbolter.jpg|thumb|right|[[Josiah W. Dogbolter]] orders [[Gol Clutha]] to kill the Doctor and [[Maxwell Edison]]. ([[COMIC]]: ''[[The Stockbridge Showdown (comic story)|The Stockbridge Showdown]]'')]]
Setting up the downfall of [[Josiah W. Dogbolter]], the Doctor froze the villagers of [[Stockbridge]] in [[2016]] "between nanoseconds" to keep them safe, and called for his friends for help him. He had the shape-shifting [[Whifferdill]] [[Frobisher]] take the form of one the Doctor's old opponents, [[Chiyoko]], to lure Dogbolter into Stockbridge. He had [[Majenta Pryce]] blackmail the major shareholders of Dogbolter's company, [[Intra-Venus, Inc.]], into giving her their shares for a low price, and had Lady [[Destrii]] of the [[Oblivion Empire]] brought along to defend her against Josiah's daughter [[Berakka Dogbolter]]. Landing in Stockbridge, the Doctor found [[Maxwell Edison]], who because of his TARDIS travels was unaffected by the time freeze. The Doctor pretended to surrender himself to Dogbolter inside [[St Justinian's Church]], and revealing his identity, Frobisher incapacitated Dogbolter's henchmen. [[Izzy Sinclair]] arrived at the church to knock Dogbolter out, and [[Sharon Davies|Sharon Allen]] broadcast Dogbolter's confession to murdering thousands on the [[Galactic Broadcasting Corporation]] in Dogbolter's century. This led to Dogbolter's arrest, the seizing on his assets and Majenta becoming the new CEO of Intra-Venus. The Doctor subsequently returned the villagers to normal.

[[File:Petals comic.jpg|thumb|right| The Doctor is possessed by [[the Plant]]. ([[COMIC]]: ''[[Petals (comic story)|Petals]]'')]]
Needing some time to relax alone, the Doctor visited [[Eed'n]] to take photo's of the native flora and fauna. After taking a few pictures, he disappointingly discovered that [[Jain Relph]], a [[professor]] from the [[Mega Galactic University]], was also on the uninhabited planet cataloging plant life. As the Doctor began to tell Relph to go away, the two were attacked by spores from Eed'n's plant life and were possessed by an entity called [[the Plant]]. The Plant realized that with the Doctor's TARDIS it could go to the beginning of the Universe and seed itself into all lifeforms. However, due to the Doctor having multiple personalities the Plant had difficulty in completely absorbing him. The Doctor used the little control he had not to pilot the TARDIS to the beginning of time, but to the end, where the Plant died due to lack of sunlight. The Doctor then dropped off Relph at a nearby human colony. ([[COMIC]]: ''[[Petals (comic story)|Petals]]'')
 
[[File:Galerie d'art parisienne 2.jpg|thumb|left|The Doctor enters the [[Galerie d'Art de Parisiennes]]. ([[COMIC]]: ''[[Gallery (comic story)|Gallery]]'')]]
The Doctor then went to [[Paris]] in the spring of [[1909]], where he attended the grand reopening of the [[Galerie d'Art de Parisiennes]]. He discovered [[Alien (Gallery)|an alien]] which was taking people into paintings and attempting to drain their lives. The alien attacked the Doctor and pulled him into ''[[Bridge over a Pond of Water Lilies]]''. From there the Doctor was chased through multiple paintings until he discovered over victims of the alien. Using a pen, he drew a door out of the painting world and back into reality. Then he threw a can of white paint at the painting which the alien was hiding in, trapping it in the canvas. ([[COMIC]]: ''[[Gallery (comic story)|Gallery]]'')
 
[[File:Pirates of Vourakis.jpg|thumb|right|The Doctor runs away from a malfunctioning [[black hole drive]] with [[Heddy Garber]]. ([[COMIC]]: ''[[Pirates of Vourakis (comic story)|Pirates of Vourakis]]'')]]
The Doctor learned that the [[Earth Empire]] trading planet [[Vourakis 3]] was being blockaded and travelled to the planet to stop the blockade before it caused an inter-planetary war. He encounter reporter [[Heddy Garber]] and took her onto the ship responsible for the blockade in his TARDIS. They discovered that colony governor [[Ron Cordell]] hired a group of [[Skink]]s to blockade the planet and were taken prisoner by the Skinks. The Skinks tried to drop the Doctor and Garber into their ship's [[black hole drive]], but the Doctor used his sonic sunglasses to sabotage the drive, and it began to destroy the Skink ship. The Doctor and Garber ran back to the TARDIS and escaped just before the entire ship was sucked into a black hole. With Vourakis 3 saved, the Doctor dropped Garber off in [[Piccadilly Circus]] before heading off into another adventure. ([[COMIC]]: ''[[Pirates of Vourakis (comic story)|Pirates of Vourakis]]'')
 
"The [[King (Elephant in the Room)|King]]" locked the TARDIS inside his throne room, guarded by a three-headed dog, with the Doctor's only tool being a broom. The palace caretaker [[Probosco]] sneaked the Doctor into the throne room, which was covered by a humongous obstacle course. When Probosco got scared, his psychic trunk attached itself around the "bravest person in the room" — the Doctor. The two helped each other cross the obstacle course. When the trunk sensed both the Doctor and Probosco were in danger it pulled them both back up. Probosco launched the Doctor with a see-saw to get them to the TARDIS. The trunk released itself from the Doctor, and Probosco realised the Doctor may not be the bravest one in the room now. Probosco played fetch with the broom, causing the dog to chase after it. The Doctor offered to take Probosco home after he dealt with the King. ([[COMIC]]: ''[[Elephant in the Room (comic story)|Elephant in the Room]]'')
 
Surrounded by robots in the [[Forbidden Zone (The Promise)|Forbidden Zone]], the Doctor had his life saved by [[Lambert]]. Lambert and his son [[Kiron]] refused to travel with the Doctor as the Forbidden Zone was still their home, so the Doctor instead promised to help Kiron every time he was in danger by installing a low-level telepathic link to his wrist device. Many years later, when Kiron became President, the Doctor was invited to his chambers. He discovered that every time Kiron was saved, videos of him being protected went viral and he grew in power. Kiron amplified the link to control the population of the entire planet to rebuild the city and enslave their enemies. When the Doctor withdrew his protection of Kiron, the spell was broken. Realising he had done wrong, Kiron asked the Doctor to help set things right. ([[COMIC]]: ''[[The Promise (comic story)|The Promise]]'')
 
The Doctor visited the planet [[Rhodia]], whose population of three billion was being wiped out by the [[Shadow Kin]] who had emerged during the [[civil war]] that was being waged between Rhodia's two factions. He was only able to retrieve two survivors: [[Charlie Smith|Charlie]], a [[Rhodian]] prince, and the [[Quill (species)|Quill]] [[Andrea Quill|terrorist]] who was forced to protect him as punishment for her crimes. For their protection, the Doctor relocated the pair to [[Earth]], specifically [[Shoreditch]], where Quill would serve as a teacher at [[Coal Hill Academy]], with Charlie attending her classes as a sixth form student.
 
[[File:Doctor-Class.jpg|thumb|left|The Doctor entrusts Quill and her students with defending Coal Hill Academy. ([[TV]]: ''[[For Tonight We Might Die (TV story)|For Tonight We Might Die]]'')]]
When the Shadow Kin caught up with Charlie and Quill at the Coal Hill Academy autumn prom night, Quill called the Doctor for help, and he returned to Coal Hill. Confronting the king of the Shadow Kin, [[Corakinus]], the Doctor used their aversion towards [[light]] to repel them, forcing them back through the tear in [[space]] [[time]] from which they came before sealing it. Knowing that such tears would continue to threaten the school as a result of the excess [[artron energy]] in the area, the Doctor entrusted Quill and Charlie to defend against whatever would come through alongside [[Coal Hill defenders|Charlie's fellow students]] who had faced the [[Shadow King]] alongside him. Before leaving, the Doctor took [[Ram Singh]], a student who had been maimed by Corakinus, aboard the TARDIS where he healed and fitted him with a [[Lothan]] prosthetic limb to replace his severed leg. Just before leaving, the Doctor reacted to seeing Clara's name on a memorial board commemorating deceased Coal Hill staff and students, though it's unclear how much if any of his memory of her was sparked by seeing it.

The Doctor went to [[New York City]] in the [[1990s]] to undo the damage from the temporal paradoxes he had played a hand in. While there, he set up a trap to prevent anyone from interfering with his work, but fell victim to it himself; this lead him to meet [[Grant Gordon]], a child obsessed with comics who nicknamed him "Doctor Mysterio", a name the Doctor immediately took a liking to. The Doctor decided to have Grant help him, handing him the [[Hazandra]] needed to power his device. However, Grant mistook it for cold medicine he needed and swallowed the gem; as the Hazandra granted wishes, it gave Grant superpowers as he wanted to help people. The Doctor made Grant promise to never use his powers, so he wouldn't become corrupter by them. He kept an eye on Grant during his later years.

=== Brief companions ===
{{Section stub|Info from ''[[Invasion of the Mindmorphs (comic story)|Invasion of the Mindmorphs]]'' needs to be added}}
Catching up on his favourite music from all across history, the Doctor visited the Twist, a colony in the 40th century, to attend a punk concert. Meeting with the band's bassist [[Hattie Munroe]] afterwards, he observed a man called [[Jakob (The Twist)|Jakob]] being chased by police. Rescuing him, he revealed he had been accused of the murder of Idra Panatar, a local councilor, that had been carried out by fox-like creatures on the colony. At the scene at Idra's house, Jakob told the Doctor and Hattie that the authorities were attempting to cover up the creature attacks. The Doctor discovered a secret room in the house containing proof of the creatures, leading him to deduce Idra was killed to keep them from being revealed. They went to the Central Power Park to investigate, and after avoiding a police chase and an attack by one of the creatures, they escaped into an underground tunnel, which led them to the vessel that first brought humans to the Twist. The area was populated by the creatures, who revealed themselves to be called the Foxkin. Escaping into a nearby statis farm, the Doctor found pods that contained human remains.
 
Accessing the records, he found that none of the human colonists traveling to the Twist had survived the journey, despite the population apparently having been descended from them. He then deduced that the Foxkin were the original colonists all along and had cloned the deceased humans to allow the population. The group were apprehended by the Foxkin, who declared that the Doctor, Hattie and Jakob had to be kept from revealing this truth. Escaping imprisonment, the group returned to the surface. Jakob declared that the Foxkin had to be destroyed, but the Doctor revealed he had worked out that Jakob had purposefully killed Idra to stop her from revealing the Foxkin, due to his hatred of the creatures. Jakob fled, and was eventually arrested by the authorities. The Doctor and Hattie held a concert to encourage the humans of the Twist to accept and welcome the Foxkin into their society. In the aftermath, the Doctor invited Hattie for a trip in the TARDIS to get a new bass. ([[COMIC]]: ''[[The Twist (comic story)|The Twist]]'')
 
[[File:Playing House (comic story).jpg|thumb|left|The Doctor and Hattie encounter the Spyrillites. ([[COMIC]]: ''[[Playing House (comic story)|Playing House]]'')]]
While the Doctor and Hattie were having a jamming session, the TARDIS made an emergency landing, attracted by dangerous radiation levels. They arrived at a house on windswept moors, which locked itself shut upon them entering. As the two investigated the house, Hattie caught a glimpse of a holographic young girl. Following the hologram through a door, the Doctor and Hattie entered a forest, where they found a mother, Holly, searching for her family. Holly told them that the house, which was her own, had grown new rooms since she purchased furniture at an antiques fair. The Doctor discovered that void creatures known as the Spyrillites were being attracted to the house as it had a great source of arton energy. Letting the Spyrillites guide him, he found a room containing an architectural reconfiguration system, and he realized the house was actually a TARDIS.
 
The Doctor determined that an item Holly brought at the antiques fair was in fact a TARDIS shell, which was dying and leaking arton energy, causing its dimensions to spill into the house and potentially across the whole universe. After finding Holly's family, they were directed to the control room of the TARDIS. Hattie and the family fought off an attack from the Spyrillites as the Doctor programmed the TARDIS to send it to die in the heart of a star, restoring the house to normal. After another jamming session aboard his TARDIS, the Doctor returned Hattie back to her home on the Twist. ([[COMIC]]: ''[[Playing House (comic story)|Playing House]]'')
 
After picking up [[Dorium Maldovar]] to use as a ball, the Doctor went to a forested planet to play a game of [[bowling]] with [[Strax]] using robotic dinosaurs as pins. Strax arrived on the [[Time Shark]] and used himself as a bowling ball. He broke all of the dinosaurs, making it impossible for the game to continue.

Afterwards, the Doctor took Strax and the Time Shark with him in the TARDIS to help save the universe. However, instead of helping him, Strax and the Time Shark explored the TARDIS and tried on clothing in the [[TARDIS wardrobe]]. ([[COMIC]]: ''[[The Adventures of Strax & the Time Shark (comic story)|The Adventures of Strax & the Time Shark]]'')
 
The Doctor visited Paris in 1695 to view an opera. A singer, [[Julie d'Aubigny]], confronted him after the show when he refused to take part in the standing ovation. After he insulted her singing, she challenged him to a sword duel. The duel was interrupted by Cardinal Richelieu, who wanted to question the Doctor. Julie stabbed Richelieu, who then was possessed by darkness. The Doctor fled to the TARDIS and took Julie with him, knowing that there were mysterious forces at work.
 
The Doctor and Julie went to the Bibliotheque Mazarine library to find information on the forces. The Doctor used his psychic paper to get the library's curator, Bishop Mazarin, to tell him what he knew. Mazarin told them that Richelieu had created an intelligence network called the Cabinet Noir to intercept the mail of Paris and instructed Mazarin to build a secret library to store confiscated mail. Richelieu experimented with magic and opened a realm of beings, which granted him the ability to not age. Mazarin gave the Doctor the keys to the secret library and told him that Richelieu was plotting to create another portal to plunge the entire world into darkness. Before he could say anymore, he was suddenly hanged and killed by gargoyles. The gargoyles attacked and Julie managed to destroy the head of one, revealing them to be robots. The Doctor looked at a chart in the secret library and studied an astrological prediction that said the sun would be hidden by the moon, which the darkness planned to use for their invasion. The Doctor and Julie escaped the library as the gargoyles burnt it and went to warn King Louis XIV of the plan, only to find he was already posessed by Richelieu and the darkness.
 
Richelieu claimed that the darkness had been taken for granted and was fighting back. Julie was separated from the Doctor and imprisoned to be executed during the king's festival. The Doctor freed Julie by posing as her executioner. The eclipse began and the darkness began to emerge and attack. The Doctor used the sonic screwdriver and TARDIS to open a portal into the Saberhagen Quaser to spread light across the land, destroying Richelieu and the darkness. Julie asked the Doctor if she could join him in the TARDIS, but he declined. The two instead decided to finish their sword duel.

=== Living with the Collins family ===
The Doctor visited [[1972]] [[London]], intending to see a music gig. While playing his [[guitar]] on the streets, he was sighted by [[Jess Collins]], a women he and Clara had shared an adventure with previously. Although he attempted to avoid her, she followed him to [[the TARDIS]]. Jess remembered Clara and was puzzled when the Doctor indicated he no longer even remembered Clara's name (despite his earlier statements that he remembered travelling with a woman named Clara, just not her appearance or personality details). He did, however, still recall his previous encounter with Jess. The TARDIS picked up an alien distress signal in the [[London Underground]], where [[Lloyd Collins|Lloyd]], Jess' father, worked. Although the Doctor insisted that she not, Jess followed him to investigate the signal. In the tunnels, they were caught by Lloyd and then attacked by a skeletal [[Hakuai|bird creature]]. The Doctor disabled the creature with [[electricity]] from the Underground, noting it was an animated cadaver. Lloyd, injured by the creature, was taken to hospital. The Doctor scanned him and realised he had an unidentifiable bacterial infection.
 
He and Jess rushed back to the Underground to inspect the scene, where he found a telepathic node on the creature's body. Activating it, they learned that the creature was an alien called [[Moan'na]], who had fled his kind and disguised himself as a human in [[17th century]] [[London]]. The Doctor determined that Moan'na had died of the [[bubonic plague]] as a human in [[1665]], but his alien body had enhanced the illness and caused Lloyd to fall under it. The Doctor and Jess returned to the hospital and discovered Lloyd had mutated into a being like Moan'na. Lloyd knocked out the Doctor and took Jess away. Upon awakening, the Doctor and [[Devina Collins|Devina]], Jess' mother, pursued them to [[Brixton]], as the infection began mutating more people. The Doctor used the telepathic node to allow Jess and Devina to communicate with Lloyd and break the infection's control over his mind, which in conjunction with the TARDIS' telepathic circuits rewrote the [[DNA]] infections to change Lloyd and the infected back to normal. However, this overloaded the TARDIS' systems and caused it to retreat within itself. The Collins family allowed the Doctor to stay with them while the TARDIS recovered. ([[COMIC]]: ''[[The Pestilent Heart (comic story)|The Pestilent Heart]]'')
 
The Doctor dismantled the TARDIS' [[outer plasmic shell]] and put it back together in the Collins' back garden, where he let it heal. While explaining to Lloyd what had happened when he was infected, the Doctor was caught off guard by the housecat [[Tibbsy]]. The Doctor warned Tibbsy that he would be watching him. The next day, the Doctor ruined Devina's fish stew when he used his sonic screwdriver on it. The Doctor prepared tea for the family himself and cleaned up the kitchen while Devina got changed, and the Collins family was impressed by the stew he served.
 
Two days later, while trying to encourage the reweaving of the TARDIS' shell, he debated with Jess' sister [[Maxwell Collins|Maxwell]] over who would win in a fight between [[Batman]] and [[Captain America]]. Later, while Jess was reading [[M. C. Escher|Escher]] for her art history class, the Doctor recounted the times he met [[Monet]], [[Pierre-Auguste Renoir|Renoir]], and [[François Boucher|Boucher]], and when had his portrait done by the cubist artist [[Pablo Picasso|Picasso]]. While trying to light Jess' book with his sonic, the sonic ran out of power, and the Doctor was unable to use the TARDIS to recharge it. With no TARDIS to leave 1972 in, the Doctor instead offered to show Jess the universe through the art she was studying. ([[COMIC]]: ''[[Moving In (comic story)|Moving In]]'')
 
The Doctor took Jess and Maxwell to the [[National Gallery]] to show them a [[John Constable|Constable]] painting, when an alien creature was released by alien hunters from [[Kolothos]] (where hunting was outlawed) and the hunters sent [[Hound (Bloodsport)|hounds]] to chase it into the gallery. The Doctor, Jess and Maxwell followed the creature outside into [[Trafalgar Square]], and witnessed the hunter [[Skadi]] murder a policeman. The Doctor used a dog whistle to incapacitate the hounds, and when Skadi's husband [[Broteas]] killed another policeman, the Doctor knocked him out by pulling his electric whip into a fountain. Skadi murdered the small creature she was hunting, and she and her son [[Tarquel]] kidnapped Jess and Maxwell aboard her spaceship.
 
Left behind on Earth, Broteas was taken to [[Scotland Yard]] by DCI [[Jack Hayes]] on a murder charge. The Doctor offered to give him food in exchange for Skadi's comms frequency. The Doctor offered himself and Broteas to Skadi in exchange for her releasing Jess, Maxwell, and the spaceship's menagerie, which Skadi was using to release rare and exotic creatures onto alien worlds so they could be hunted for fun, and then leaving Earth. Skadi broke her promise, and sent her hounds after the Doctor in [[Epping Forest]]. The Doctor used a reprogrammed metal horse belonging to Broteas to knock the hounds over. Maxwell tricked Skadi into dropping her sword and having Hayes arrest her when he threatened Tarquel. However, this was part of a ruse to have Tarquel take his parents home to face justice for all of the killing they had done. The Doctor convinced Hayes that Skadi and Broteas facing their own people's justice would be worse off than being tried on Earth, and he let them leave Earth with Tarquel. ([[COMIC]]: ''[[Bloodsport (comic story)|Bloodsport]]'')
 
While Jess and the Doctor were delivering [[Christmas card]]s on [[23 December]], they saw [[Walter (Be Forgot)|Walter]] from across the street behaving oddly and then slamming the door. The Doctor kept an eye on Walter's house all night. The following day, [[Christmas Eve]], the Doctor saw Walter throw a snowglobe through his window. The Doctor, Jess and Devina broke in to help Walter, but no-one else was in the house but Walter. Through the guilt of losing his mother [[Carmen (Be Forgot)|Carmen]] in [[1971]] and being left alone for too long, Walter imagined the fictional character [[Obadiah Grimm]] murdering the Doctor, Jess and Devina with the touch of his hand. Walter was taken away in an ambulance to treat his mental illness. On [[Christmas]] morning, Devina invited the whole street for breakfast as a reminder that the street was a community and to remember Carmen. ([[COMIC]]: ''[[Be Forgot (comic story)|Be Forgot]]'')
 
In [[1973]], DCI Hayes invited the Doctor to Scotland Yard where they had brought in a man who had been turned into [[glass]]. Hayes took the Doctor and another officer, [[Perkins (Doorway to Hell)|Perkins]], to a warehouse in [[Barking]] where the man had been found. There, a giant mosquito attacked and turned Perkins into glass. While Hayes distracted the mosquito the Doctor electrocuted it with a generator. Afterwards, more mosquitoes attacked the warehouse. The Doctor drew the mosquitoes towards Hayes' car where they trapped their stingers in the car roof. The Doctor rigged the car to explode, killing the mosquitoes. Returning to Brixton, the Doctor realised that the events in Barking were a distraction for someone to steal the TARDIS. The Doctor and Hayes also discovered the murdered shrunken body of the Doctor's chess partner [[Gabriel Gayle]] in the Collins family garden. The Doctor and Hayes were escorted to meet {{Delgado}}, in the incarnation the Doctor met in his [[Third Doctor|third incarnation]]. The Master murdered Hayes when he tried to arrest him, and told the Doctor the Collins family were running errands for him when he used the artron energy in their bodies to open a portal to a [[time lock]]ed dimension. The Master linked the Doctor's now fully regenerated TARDIS to [[the Master's TARDIS]] to aid the Doctor through the time lock so he could be reunited with the Collins family. The Master had his mercenary companion [[Katya Dabrowski]] accompany the Doctor there.
 
Followed by the Master, the Doctor met [[Kiadine]], a being the Time Lords imprisoned for ravaging his world by splitting the [[chronon]]. Kiadine gave his life and his temporal powers to the Master. After the Master aged Katya to death, the Doctor and the Master fought with each other over the power of the chronon storm, when the Collins family pulled the Doctor back, standing together against the Master. The Master attacked them, and this blast was repelled with the same artron energy in the bodies of the Collins family that had brought the Master to the dimension. The Master survived this attack and left, and with no-one left to keep time in check, the Doctor and the Collins family evacuated. After Gabriel's funeral, the Doctor said goodbye to the Collins family and left, believing he had outstayed his welcome. ([[COMIC]]: ''[[Doorway to Hell (comic story)|Doorway to Hell]]'')
 
=== Returning Jata home ===
[[File:Jata wanted poster.jpg|thumb|left|[[Molly Zook]] shows the Doctor wanted posters for [[Clint Currie]] and [[Jata]]. ([[COMIC]]: ''[[From the Horse's Mouth (comic story)|From the Horse's Mouth]]'')]]
The Doctor tracked a crashed [[Q7 starship]] to the [[Wyoming]] desert in [[1899]] and encountered the bounty hunter [[Molly Zook]]. Molly was tracking the big-time criminal [[Clint Currie]]. She showed the Doctor wanted posters of Currie and [[Jata|his horse]], which the Doctor recognised as an [[Osumaran]] masquerading as a horse. He followed Molly to a nearby town where Currie's gang were robbing a train. The Doctor bought a horse and painted a star on its forehead so it resembled an Osumaran. He then went to where the gang had tied up their horses and replaced the alien with a real horse.
 
[[File:Jata meets Doctor.jpg|thumb|right|The Doctor takes Jata as a reward for capturing Clint Currie. ([[COMIC]]: ''[[From the Horse's Mouth (comic story)|From the Horse's Mouth]]'')]]
Without the Osumaran to guide him, Currie was caught and arrested by [[Sheriff (From the Horse's Mouth)|the town's sheriff]]. The Doctor asked to keep Currie's horse as a reward for helping with the capture. The Osumaran introduced himself as Jata and thanked the Doctor for rescuing him from a life of crime. The Doctor decided that Jata's starship was too broken to work again and decided to take Jata back to [[Osumare]] in the TARDIS. ([[COMIC]]: ''[[From the Horse's Mouth (comic story)|From the Horse's Mouth]]'')
 
[[File:Fear Buds.jpg|thumb|left|The Doctor and Jata surrounded by zombie-like students. ([[COMIC]]: ''[[Fear Buds (comic story)|Fear Buds]]'')]]
During the trip to Osumare, Jata mentioned he was interested in educational systems, which prompted the Doctor to show him an [[England|English]] school in the [[21st century]]. Much to the Doctor's surprise, the school they landed in was filled with students put into a violent trance by their [[ear bud]]s. The Doctor and Jata hid in the school's chapel with three teachers and [[Ralph (Fear Buds)|a student]]. The Doctor knew about a secret room in the chapel and guided the student, Jata, and [[Swain|one of the teachers]] to it when the mind-controlled students broke through the chapel's doors. In the hidden room, the Doctor realised that the student was a [[Mkali]]. He confronted the Mkali and asked him to reverse what he had done to the other students. When that didn't work, the Doctor called the Mkali's mother, who became very angry at her son and fixed everything he did. ([[COMIC]]: ''[[Fear Buds (comic story)|Fear Buds]]'')
 
=== Adventures with Alex and Brandon ===
{{Section stub|Info from ''[[The Lost Angel (audio story)|The Lost Angel]]'' and ''[[The Lost Planet (audio story)|The Lost Planet]]'' needs to be added}}
On [[Rickman]], the Twelfth Doctor met [[Alex Yow|Alex]] and [[Brandon Yow]]. With the help of the two siblings, the Doctor was able to defeat a [[Weeping Angel (The Lost Angel)|Weeping Angel]]. After this encounter, Alex and Brandon started to travel with the Doctor in [[The Doctor's TARDIS|the TARDIS]]. ([[AUDIO]]: ''[[The Lost Angel (audio story)|The Lost Angel]]'')
 
=== Travels with Hattie ===
[[File:Beneath_the_Waves_12_Runs_From_Quarks.jpg|thumb|The Doctor instructs his allies to run from the [[Quark]]s. ([[COMIC]]: ''[[Beneath the Waves (comic story)|Beneath the Waves]]'')]]
The Doctor arrived on board a high-paying [[Ship (Beneath the Waves)|ship]], stuffed with [[Aristocrat|aristocrats]] from various species, which attempted to discover and excavate a lost city hidden below the waves of [[New Oceana]]. The team eventually arrived to the doors of the [[Saffshran Ziggurat]], which had been sealed for almost a thousand years. The group was greeted not by lost artifacts or treasure, but by a an awoken army of [[Quark]]s who swiftly attacked the group. Realising that the Ziggurat was a Quark [[Manufactorum]], the Doctor flooded the city as the team escaped using their [[Rebreather|breathing devices]].
[[File:Beneath_the_Waves_12_Runs_with_Hattie.jpg|thumb|left|The Doctor and Hattie run. ([[COMIC]]: ''[[Beneath the Waves (comic story)|Beneath the Waves]]'')]]
Still soaked, the Doctor arrived on the colony planet of the [[Twist|The Twist]] where he discovered a now-famous [[Hattie Munroe]] attempting to escape from the media. The Doctor took Hattie to [[Seaton Bay]] in the year [[1979]]. There they discussed that Hattie didn't feel fully satisfied, despite accomplishing most of her dreams in life. As the conversation wrapped up, the Doctor realised that a newspaper holding Hattie's comfort [[Chips|chips]] revealed that mysterious figures had been seen entering the sea. Spotting one of these mysterious sea-weed based creatures, the Doctor convinced Hattie to stay the night at [[The Grand Hotel|a local hotel]].
 
As Hattie slept, the Doctor returned to the TARDIS and built a device, which he designated a [[Transpychograph-u-lator]]. Returning to the hotel, the Doctor discovered that a patron had entered having hit one of the creatures with her car. Investigating the crashed car and the dispersed being, the Doctor was shocked to witness Hattie turn into one of these creatures. ([[COMIC]]: ''[[Beneath the Waves (comic story)|Beneath the Waves]]'')
 
=== River and Darillium ===
Relaxing in his TARDIS after a "long day" that had involved "everybody turn[ing] into [[lizard]]s" and a [[piano]] falling on him, the Doctor was mistakenly summoned by [[Nardole]] for a "medical emergency" and brought to [[River Song]], who failed to recognise the Doctor due to not knowing about his new regeneration cycle, as her husband, King [[Hydroflax]], needed a lifesaving operation to remove the [[Halassi Androvar]] diamond from his head. However, River intended to remove Hydroflax's head, and managed to steal it when Hydroflax, whose head was dispensable, discovered the ruse and tried to kill her and the Doctor, until the Doctor took his head hostage and, with the robotic body unwilling to potentially harm Hydroflax's head, the Doctor and River managed to get teleported out by [[Ramone]], another of River's husbands.
 
Arriving back at the TARDIS, the Doctor and River, still not knowing his identity, "stole" the TARDIS to get away from Hydroflax's body, but the TARDIS could not dematerialise with the head inside and the body outside, and River was tricked into letting the body in after it stole Ramone's head. Escaping the body on the ''[[Harmony and Redemption]]'', River tried to sell the diamond to [[Scratch]] of the [[Shoal of the Winter Harmony]], only to learn that he was a follower of Hydroflax, and the two attempted to leave with Hydroflax's head. However, Hydroflax's robotic body arrived and killed the head, having been promised the Doctor's head as a replacement. To the Doctor's sorrow, he listened to River as she showed a lack of belief in his love for her, saying that while she loved him, he didn't fall in love with people. As the Doctor revealed who he was to River, River told the Doctor she was "just keeping them talking". As a [[meteor storm]] hit the ship, the Doctor and River attempted to stop the ''Harmony and Redemption'' from crashing on [[Darillium]], but ultimately failed, barely shielding themselves in the TARDIS instead during the impact.
 
[[File:River and Twelve Happy.jpg|thumb|The Doctor and River during their final night together. ([[TV]]: ''[[The Husbands of River Song (TV story)|The Husbands of River Song]]'')]]
Regaining consciousness first, the Doctor emerged from the TARDIS on Darillium, and, using the diamond, inspired a man called [[Alphonse]] to start a restaurant, so he could travel into the future and book a reservation for a balcony view of the [[Singing Towers]]. Dressing formally for River when she awakened, the Doctor gifted her a sonic screwdriver of her own, and, telling her that nights on Darillium lasted 24 years, the two enjoyed the view. ([[TV]]: ''[[The Husbands of River Song (TV story)|The Husbands of River Song]]'') True to his word, the Doctor stayed with River on Darillium for twenty-four years before River left to meet her ultimate fate in [[the Library]], after which the Doctor, afraid of being alone, recovered Nardole from Hydroflax's body and took him on as his [[companion]] after reattaching his head to his body.
 
In the [[2010s]], the Doctor learned that [[Harmony Shoal]] had invaded the capital cities of Earth, and was working to stop them from implanting themselves in the heads of the world leaders. This led him to meet the adult Grant, who was now the heroic vigilante known as the Ghost. Together, they stopped Harmony Shoal, by destroying their spaceship before it could be dropped and decimate Earth. With this over, the Doctor decided to leave on new adventures with Nardole, who explained to Grant and his new girlfriend [[Lucy Fletcher]] the Doctor was in a grieving period for the time being as he had recently lost River Song. ([[TV]]: ''[[The Return of Doctor Mysterio (TV story)|The Return of Doctor Mysterio]]'')
 
=== Working with the Ghost ===
Some time later, the Doctor returned to Grant, eight years later from Grant's perspective, to get his help finding the other gems that gave him his power. However, Grant only agreed to come if Lucy and Jennifer came too. ([[COMIC]]: ''[[Ghost Stories (comic story)|Ghost Stories]]'')
 
=== St Luke's University ===
After "a thing happened", ([[TV]]: ''[[Smile (TV story)|Smile]]'') the Doctor began to lecture at [[St Luke's University]] to keep guard over [[Vault (The Pilot)|a vault]] with Nardole. ([[TV]]: ''[[The Pilot (TV story)|The Pilot]]'') As a result of "the thing", the Doctor made a promise to someone that prevented him from "going off-world unless it [was] an emergency". ([[TV]]: ''[[Smile (TV story)|Smile]]'')
 
Fifty years into his position, the Doctor recognised that one of the attendants to his lectures wasn't a student, and indeed worked in the [[cafeteria]]. Growing admiration with her fascination in things she couldn't understand, the Doctor enrolled her in the school and offered to become her personal tutor.
 
Bill would meet the Doctor everyday at 6 pm, and Bill would keep up her promise to keep up a continuously solid grade rate. On [[Christmas]] of that year, Bill would gift the Doctor a rug. The Doctor, troubled that he had not given her an equivalent gift, travelled back in time and took photos of [[Bill Potts' mother|her mother]]. Bill would find these in her closet the following day, and would briefly recognise the face of the Doctor in the mirror of one of the photos.
 
Bill at one point entered his office slightly off-kilter, a clear side-effect of recent discomfort. Bill explained to the Doctor that one of her new acquaintances, [[Heather (The Pilot)|Heather]], had dissapeared mysteriously moments before while studying a [[sentient oil|a puddle]]. As she spoke, the Doctor urgently exited the room and ran to the puddle. There he and Bill came to the conclusion that the puddle wasn't reflecting their image, but rather that it was imitating their movements. Hoping to disperse Bill from the situation, the Doctor cancelled their tutor cession and sent Bill home.
[[File:The_Pilot_Doctor_Do_You_Know_Sci_Fi.jpg|left|thumb|The Doctor is asked by Bill if he knows anything about [[Sci-Fi]]. ([[TV]]: ''[[The Pilot (TV story)|The Pilot]]'')]]
Later that night, Bill returned to his [[The Doctor's office (The Pilot)|office]], trailed closely by the Heather-imitating-puddle. Running into the TARDIS, and greeted by Nardole, he took her to the vault. Heather soon gave pursuit, and they were able to discover that it was indeed after them and not the contents of the vault. Using the TARDIS, the Doctor lead the creature to [[Australia]], a [[Planet (The Pilot)|planed at the other end of the universe in the future]], and eventually a [[War zone (The Pilot)|war zone]] in the [[Dalek-Movellan War]].
 
Eventually, they were able to discover that the but creature didn't mean her harm, but was following because Heather had promised not to leave without Bill. Bill released Heather from her promise and it departed. The Doctor took Bill back to the University, planning to mindwipe her, but relented when she asked how he'd feel if it was done to him, and told her to leave. Taking the TARDIS outside the university to greet her, the Doctor stated that she was welcome to travel with him in the TARDIS and that they would surely meet Heather again. ([[TV]]: ''[[The Pilot (TV story)|The Pilot]]'')
 
==== Travels with Bill ====
{{Section stub|Info from ''[[The Shining Man (novel)|The Shining Man]]'', ''[[Diamond Dogs (novel)|Diamond Dogs]]'', ''[[Smile (TV story)|Smile]]'' and ''[[Thin Ice (TV story)|Thin Ice]]'' needs to be added}}
The Doctor took Bill to visit a [[Gliese 581 D|human colony]] in the [[far future]] lying to Nardole that he was just transporting the TARDIS back to the office.  The Doctor recognised the Vardy robots flittering above them and was suspicious when no humans were in the facility.  He and Bill were handed badges by an [[Emojibot]] that greeted them on their arrival and displayed their mood states on their backs.
 
As Bill sat down for food, the Doctor revealed he was two hearted- the reason why the Emojibot had given him two portions as it registered two lifeforms- and that he once knew an emperor made of algae who fancied him.  He came to the conclusion that the colonists were schduled to arrive and the Emojibots and Vardy were the set up team instead of humans.  In the gardens of the colony, the Doctor discovered a pendant with the hologram of a child waving in it revealing that there had been humans in the colony at some point.
 
He hid his discovery from Bill until they came across an Emojibot tending to plants whilst a sprinkler system delivered a carbon-based fertiliser to them.  On scanning the machine, the Doctor used the sonic screwdriver to unlock the compartment revealing a large amount of bones and skulls to his and Bill's mutual horror.  The Doctor examined a skull and seemed able to form some kind of link with the victim revealing the Vardy had killed them.
 
The Emojibot sensed their distress and fear and proceeded to chase them.  When Bill commented it was very slow, the Doctor pointed out that that only meant there was a reason it didn't have to run.  They were cornered by the Emojibots but the Doctor worked out a way to trick them by smiling which would confuse the badges displaying their emotional state and allow them to pass. 
 
After escaping the colony, the Doctor ran back in to blow it up and save the colonists from the Vardy.  He warned Bill not to look at his browser history before running back inside and smiling to get past the Emojibots he ran into.  When Bill joined him, having followed, he showed her that the Vardy were actually a part of the building and had constructed the colony using themselves.  He had Bill give him directions to the main power centre before revealing he had memorised the schematics.
 
After wiring the colony to blow, he was attacked by an Emojibot as he tried to stop a wheel from turning.  He kicked it off the ledge and then ran back to Bill to find her with the same boy he had seen in the holographic pendant.  The Doctor realised that the colonists were already there in hibernation and by entering the ship, he and Bill were causing them to wake up.  The Doctor stopped the bomb and, after discovering the body of an elderly woman realised what had actually happened.
 
The Vardy and Emojibots were designed to make people happy, but the set up team's grief at the death of an old woman who had died from natural causes, made them believe grief was the enemy of happiness and set about trying to eradicate it.  He compared it to the story of the magic haddock before meeting the colonists and revealing what had happened to the set up team.  This prompted the colonists to begin arming themselves despite the Doctor insisting they just try and escape and that the Vardy were just confused.
 
When the boy realised his mother was dead, his emotional badge revealed his distress causing the Emojibots to target him.  The colonists opened fire prompting the Vardy to attack causing the Doctor to realise that the Vardy and Emojibots were alive.  He then rewired the Vardy hitting the reset button and removing their ned to make people happy before beginning diplomatic negotiations between the humans and Vardy.
 
The Doctor tried to return to the university just after they left, but when he and Bill exited the TARDIS discovered they were outside in winter with an elephant in front of them.  ([[TV]]: ''[[Smile (TV story)|Smile]]'')
 
After the initial confusion, it was revealed they were in London, though Bill assumed it was a parallel world, the Doctor assured it was their own and they were at the last Frost Fair in 1814.  He and Bill dressed in period clothing before exploring Regency London.  When Bill queried the safety of time travel- worrying she would step on a butterfly and cease to exist- the Doctor joked that she had a friend named Pete who was right with them and stepped on a butterfly.
 
A young girl gave them a flyer inviting them to the Frost Fair on the Thames which they both attended.  They witnessed wrestling, which the Doctor claimed "[wasn't] really wrestling unless it [was] in zero gravity... with tentacles" and Bill remarked that Regency London was more ethnically diverse than in movies.  The Doctor pointed out that so was Jesus and that history was a whitewash.  He later stole some pies from a fisherman after believing he was swindling them. At some point, the Doctor noticed the green glowing lights under the ice but said nothing to Bill until she noticed as well since she was enjoying herself.  They were approached by Kitty, a street urchin, who claimed to have lost her dog but the Doctor quickly deduced she was conning them- proven when a boy pickpocketed his sonic screwdriver.
 
Giving chase, their way was blocked by a group of acrobats giving Bill and the Doctor time to argue over how his sonic screwdriver was sonic or a screwdriver.  They eventually spotted the urchins chasing the, across the ice before the boy, Spider, became distracted by the lights under the ice and was sucked under.  His arm clutching the sonic was still sticking out of the ice and though the Doctor tried to save him, he was only able to retrieve his screwdriver before the boy was sucked under the ice completely. 
 
Bill was appalled by his seeming lack of care towards the boy who had just died when the Doctor said he could not save him.  The Doctor promised to help Kitty before she noted that Bill had run off.  When he found her, Bill confronted him demanding to know how many people he had seen die- he didn't know and he had moved on- and then how many people he had killed.  The Doctor was visibly perturbed by her questioning but claimed that at 2000 years old he didn't have time or luxury for outrage and that unless he moved on, more people would end up dying. 
 
Kitty led them to the gang of urchins including the girl who had offered a flyer to Bill.  To distract the children when they began asking about Spider, the Doctor gave them the pies he had stolen earlier and read them a story.  Gaining their trust, the urchins revealed that a man with a ship tattoo on his hand paid them to get people onto the ice.  The Doctor and Bill then put on dive suits and went out onto the ice so as to discover what the creature was beneath the Thames.  They could not hear each other in the helmets and it was only when Bill threw her lantern at him that he noticed she was about to be sucked under. 
 
Underneath the Thames, they discovered a large sea monster chained down to the riverbed and agreed that it sounded distressed.  The Doctor caught the fisherman from earlier who pointed them in the direction of the river dredgers.  Under the pretence of conducting an inspection, the Doctor was able to trick the Supervisor into revealing that they were dredging the creature's waste as it burned longer than coal and even underwater.  He also revealed their employer, Lord Sutcliffe who owned the Steel Mill the waste was sent to.
 
Inside Sutcliffe's home, the Doctor asked Bill to let him do the talking as he would be able to stay calm in front of a potentially extra-terrestrial being who they may need to charm to get information from since she was already upset from the deaths she had seen.  Under the guise of "Doctor Disco of the Fairbrook Society", the Doctor was welcomed by Sutcliffe until the latter saw Bill.  After Sutcliffe made sexist, classist but mainly racist comments towards her, he tapped him on the shoulder before punching him in the face. 
 
Captured by Sutcliffe's men, one of who bore a seaship tattoo on his hand, Sutcliffe revealed that his family had known about the sea creature for years and the fuel it provided was accelerating industrialism.  The Doctor made a speech about how it was the value of life that defined a species rather than its industry which failed to move Sutcliffe.  They were both tied up with a tent full of explosives on the ice as Sutcliffe planned to blow the ice to give the creature more food before and hide its existence when the ice thawed.  Working together, the Doctor and Bill managed to get the sonic screwdriver and used it to cut through the rope whilst luring the glowing fish towards them.
 
One of Sutcliffe's minions took the screwdriver causing him to be sucked through the ice as the Doctor got it back.  The Doctor then gave Bill the choice of what to do as he existed to serve the human race making her in charge of him.  She chose to save the creature and whilst she cleared the ice, the Doctor used a dive suit to plant the explosives around the chains of the sea creature instead.  As the ice cracked from the creature's escape, killing Sutcliffe, he rescued Bill pulling her off of the ice before they got soaked as the sea creature passed them by.
 
Later, he and Bill invited the urchins to Sutcliffe's home where he amended Sutcliffe's Will to name Perry, one of the urchins, as his heir.
 
Upon returning to St Luke's, Nardole entered having just made tea and remi the Doctor of his oath not to leave Earth.  When Bill was confused by how no-one had reported anything on the sea creature, the Doctor explained that humans had an ability to ignore the inexplicable and that the Frost Fair had involved a lot of day drinking.  It was revealed that his efforts to provide for the urchins were rewarded as, despite some contest, Perry was deemed the legitimate heir. 
 
The Doctor then tossed a coin with Nardole; Heads- he stuck to his oath- or Tails- Nardole left him alone and he could go travelling.  The coin toss landed on Tails. ([[Thin Ice (TV story)|TV: ''Thin Ice'']])

[[File:Four_Doctors_Ten_and_Twelve_argue.jpg|thumb|left|The Tenth and Twelfth Doctors argue. ([[COMIC]]: ''[[Four Doctors (comic story)|Four Doctors]]'')]]
In the version of time where the alternate [[Gabby Gonzalez]] hailed from, the Doctor followed Clara to the café and barged in after his two previous incarnations had. The [[Tenth Doctor]] refused to consider the Twelfth Doctor as a possible incarnation of himself, as he had already confirmed the [[Eleventh Doctor]] as his successor, and knew that he had only one regeneration left. Although the Eleventh Doctor tried to break them up, the Tenth and Twelfth Doctors argued until they brushed fingers, causing a spark of the [[Blinovitch Limitation Effect]]. All three Doctors realised they had caused a paradox at a fixed point in time, resulting in the appearance of the [[Reaper]]s.
 
[[File:Four_Doctors_10,_11,_12_Two.jpg|thumb|The three Doctors in the TARDIS. ([[COMIC]]: ''[[Four Doctors (comic story)|Four Doctors]]'')]]
While the Reapers chased the Eleventh Doctor, the Tenth and Twelfth Doctors, Clara, Alice and Gabby ran back to the Eleventh Doctor's TARDIS, only to find the Reapers' presence had turned it into an empty shell. As the Eleventh Doctor returned, the three Doctors touched to send a narrow focus beam, docking their TARDISes together and restoring its exteriors. As the Reapers continued their pursuit, the group made their way to the Tenth Doctor's control room where the Twelfth Doctor set it to dematerialise, thus forcing the Reapers out. Although this worked, the Twelfth Doctor was worried about how his other selves would perceive his actions, to which Clara encouraged him to have some "me time" and to work things out. ([[COMIC]]: ''[[Four Doctors (comic story)|Four Doctors]]'')
 
While Clara, Alice and Gabby went elsewhere, ([[COMIC]]: ''[[The Meeting (comic story)|The Meeting]]'') the three Doctors participated in an open microphone night, thogh the Twelfth Doctor left after the audience did not take to his set up. Believing they should try karaoke, ([[COMIC]]: ''[[Open Mic Night (comic story)|Open Mic Night]]'') the Doctors instead tried their hand at classical comedy, though the twelfth incarnation's sense of humour turned sour, to which the tenth incarnation turned apologetic for. ([[COMIC]]: ''[[The Doctors Do... Classic Comedy (comic story)|The Doctors Do... Classic Comedy]]'')
 
Back in Paris, Clara revealed that the three Doctors had had an encounter on the planet [[Marinus]] in the circumstances of a catastrophic event. Unable to contain their curiosity, the Doctors travelled to Marinus to find out what would happen. There, after they were attacked by a mysterious beam, the Doctors began bickering and inadvertently ended up in the pose from the photo.
 
[[File:Four Doctors Alternate Twelfth Doctor Meets normal 12.jpg|thumb|left|The Doctor encounters an [[Twelfth Doctor (Four Doctors)|alternate version of himself]]. ([[COMIC]]: ''[[Four Doctors (comic story)|Four Doctors]]'')]]
Forced to split up in a maze by their attackers, the Twelfth Doctor ended up with Gabby, who criticised him for his views on the others, while the Doctor defended himself as being more "wholemeal" than the "skinny, low carb, free range Doctor" she was used to. Navigating the maze, the six met up at the middle of the maze, where a [[continuity bomb]] detonated and turned them all into time ghosts, traveling to different timelines made by the Doctors' decisions. These alternative timelines included one where the Tenth Doctor allowed [[Wilfred Mott]] to die in the radiation chamber, one where the Eleventh Doctor allowed [[River Song]] to spare him on [[22 April]] [[2011]], and one where the Twelfth Doctor would become an paranoid recluse inside the TARDIS after a betrayal Clara had committed against him. In order to escape from the loop, the Doctors committed to the twelfth incarnation's future, as it seemed to be the least dangerous of the three, so the Twelfth Doctor poked his alternate self to become whole again. The [[Twelfth Doctor (Four Doctors)|alternative Twelfth Doctor]] was surprised to see Clara again, but recognised everyone else and agreed to give everyone a lift, which the Eleventh Doctor accepted on everyone's behalf. They materialised in a small pocket universe and were approached by the [[Voord]], who offered the alternative Twelfth Doctor a capsule. All of them were horrified to see the alternative Doctor merge with the suit, revealing that he planned all of this from the start and that he was the leader of the Voord.
 
After the alternative Twelfth Doctor revealed how he found companionship and healing in the Voord city, and had arranged the meeting of the Doctors to ensure his timeline would be whole, which the Tenth and Eleventh Doctors found a very [[wibbly wobbly, timey wimey|timey wimey]] plan, he announced his intent to erase the Gabby, Alice and their Doctors' memories of the event, but implant mental commands in the Twelfth Doctor and Clara's minds to ensure they would fall out in the betrayal, allowing the Twelfth Doctor to become his alternate self and lead the Voord on a universal conquest. As they were being led to have their memories altered, the Tenth and Eleventh Doctors staged a distraction, allowing Gabby and Alice to escape. The Doctors and Clara were then taken to the Conscience, where the alternative Twelfth Doctor altered their memories, and sent them back to their own universe to live out their new destinies.
 
As the alternative Twelfth Doctor gloated about his victory, Alice was killed by his Voord guards and Gabby began to frantically open the Doctor's comics in the hope they could help her. Much to her horror, inside the bundle was a miniature Weeping Angel, which grew to full size and sent her back in her own personal timeline to the café before the three Doctors arrived to greet their companions. Gabby warned the companions of what would occur if things went they way they had before, before fading from existence. ([[COMIC]]: ''[[Four Doctors (comic story)|Four Doctors]]'')

[[File:Twelfth Doctor in light Mummy on the Orient Express.jpg|thumb|left|Unfazed by [[Gus (Mummy on the Orient Express)|Gus]]'s threats, the Doctor ponders the [[Foretold]]'s modus operandi. ([[TV]]: ''[[Mummy on the Orient Express]]'')]]
A cynical man armed with a dry, acerbic wit, a brutal honesty and enough internalised anger to overpower [[Empath]], the Twelfth Doctor was a radical change from [[Eleventh Doctor|his predecessor]], adopting a less caring attitude and more hostile nature, ([[TV]]: ''[[Into the Dalek]]'', ''[[Robot of Sherwood]]'', ''[[Listen]]'', ''[[The Caretaker]]'', ''[[Dark Water (TV story)|Dark Water]]''; [[PROSE]]: ''[[Silhouette (novel)|Silhouette]]'') though he believed he gave people the benefit of the doubt. ([[PROSE]]: ''[[The Blood Cell]]'') He was perfectly comfortable with placing his companions in danger if it meant appeasing his curiosity, often leaving them out of the details in his plans, or using them to distract attention away from himself. ([[TV]]: ''[[Deep Breath]]'', ''[[The Caretaker]]'', ''[[Kill the Moon]]'', ''[[Mummy on the Orient Express]]'') However, if he believed the situation was too dangerous for them, the Doctor would either recruit necessary assistance, ([[PROSE]]: ''[[The Crawling Terror]]'') or send his companions to the safety of the TARDIS while staring down the threat alone. ([[TV]]: ''[[Listen]]'', ''[[Before the Flood]]'', ''[[Smile (TV story)|Smile]]'')
 
The Doctor preferred to be in the moment, where "everything is huge, everything is so important, every detail, every moment, every life clung to [the moment]." He claimed to the [[Half-Face Man]] that the people of [[Earth]] "[were] never small to [him]," and, unlike his tenth incarnation, he didn't think he deserved [[Final reward|a reward]] or a "promised land" because he had "already [gone] a very long way [to protect the people]", ([[TV]]: ''[[Deep Breath]]'') and become a lost soul beyond redemption because of it. ([[TV]]: ''[[Face the Raven]]'') He also valued mortal lives, however brief they seemed to him, telling [[Ashildr|Lady Me]] that she would become his enemy if she executed [[Sam Swift]] while he was at her mercy, ([[TV]]: ''[[The Woman Who Lived]]'') and forbade [[Weezie]] from speaking to him after he learned she killed [[dragon]]s for sport. ([[COMIC]]: ''[[The Dragon Lord (comic story)|The Dragon Lord]]'')
 
He "[found] it best to keep an open mind, unclouded by the opinions of others", favoured the direct approach when he encountered an obstacle, and believed it was always best to assume and plan for the worst-case scenario. ([[PROSE]]: ''[[Silhouette (novel)|Silhouette]]'') He also viewed pain as a gift, telling a [[Cyber-converted]] [[Danny Pink]] that "without the capacity for pain, [you] can't feel the hurt [you] inflict," ([[TV]]: ''[[Death in Heaven]]'') and also believed that "a bit of shame never hurt anyone," ([[TV]]: ''[[The Witch's Familiar]]'') and that true [[immortality]] was "everybody else dying". ([[TV]]: ''[[The Girl Who Died]]'')
 
Despite coming across as uncaring, with a complete disregard for social niceties, he would fight to protect those in his care, and he would react with devastation if harm befell them. Such was his reaction to the death of a female [[Tyrannosaurus rex]] that had been inadvertently dragged through time by the TARDIS, ([[TV]]: ''[[Deep Breath]]'') to the death of Guardian [[Gillian Donaldson]], ([[PROSE]]: ''[[The Blood Cell]]'') and when [[Ashildr]] suffered heart failure due to his plan to repel the [[Mire]]. ([[TV]]: ''[[The Girl Who Died]]'') He would also regret the deaths of good people, especially if the survivors displayed an unpleasant attitude. ([[TV]]: ''[[Flatline]]'')
 
However, for the most part, the Doctor preferred to largely keep his softer side hidden under a "reputation for grumpiness", ([[COMIC]]: ''[[The Hyperion Empire (comic story)|The Hyperion Empire]]'') making him act callous towards grieving individuals, ([[TV]]: ''[[Into the Dalek]]'', ''[[Kill the Moon]]'', ''[[Dark Water (TV story)|Dark Water]]'', ''[[The Girl Who Died]]'') leave murdered bodies he found undisturbed to avoid either awkward questions or the cause of the killing, ([[PROSE]]: ''[[Silhouette (novel)|Silhouette]]'', ''[[The Crawling Terror]]'') and neglect to ask for people's names because they were "not [his] area". ([[TV]]: ''[[Deep Breath]]'', ''[[In the Forest of the Night]]'') He eventually began using [[Apology cue cards|cue cards]] to help him socialise. ([[TV]]: ''[[Under the Lake]]'')
 
The Doctor also showed a strong compassionate streak, running into a burning library to save [[Lafcardio]] from being ejecting into space, ([[PROSE]]: ''[[The Blood Cell]]'') putting himself in harm's way to save [[Maisie Pitt]] from the Foretold, ([[TV]]: ''[[Mummy on the Orient Express]]'') assisting Clara even after she had attempted to blackmail him, ([[TV]]: ''[[Dark Water (TV story)|Dark Water]]'') giving [[Davros]] some of his regenerative energy to allow him to see a Skarosian sunrise before he died, ([[TV]]: ''[[The Witch's Familiar]]'') and sacrificing his [[TARDIS key]] to reunite [[Anahson]] with [[Anah|her mother]]. ([[TV]]: ''[[Face the Raven]]'') He would also try to avoid harming those who were not in control of their actions, as well as defend them from their captors or those who would cause them further harm. ([[PROSE]]: ''[[Silhouette (novel)|Silhouette]]'', ''[[The Crawling Terror]]'')
 
The Doctor held a veneration of the dead. As such, he ceased all insults towards [[Danny Pink]] after being told of his passing, ([[TV]]: ''[[Dark Water (TV story)|Dark Water]]'') and was morally outraged with the [[Fisher King]] for using the souls of the dead as transmitters for his armada. ([[TV]]: ''[[Before the Flood]]'')
 
[[File:TITAN 12th 1 TheDoctor.jpg|thumb|The Doctor compares himself to his predecessor. ([[COMIC]]: ''[[Terrorformer (comic story)|Terrorformer]]'')]]
While he described himself as having had "sophistication and timeless sartorial elegance" restored, ([[COMIC]]: ''[[Terrorformer (comic story)|Terrorformer]]'') the Doctor was not above acting childish; requesting a children's menu at [[Mancini's Family Restaurant]], ([[TV]]: ''[[Deep Breath]]'') wriggling his toes to make the pigs on his socks dance, ([[PROSE]]: ''[[The Blood Cell]]'') whistling "[[Another Brick in the Wall]]" to annoy Clara, ([[TV]]: ''[[The Caretaker]]'') doing a victory dance after moving the TARDIS off a train line, ([[TV]]: ''[[Flatline]]'') ecstatically steering [[Santa Claus]]'s sleigh, ([[TV]]: ''[[Last Christmas (TV story)|Last Christmas]]'') looking for ways to avoid concentrating on something he did not want to dwell on, ([[TV]]: ''[[The Doctor's Meditation]]'') having impulses to blow things up, ([[TV]]: ''[[Smile (TV story)|Smile]]'') and bickering with the likes of [[Robin Hood]] and Father Christmas. ([[TV]]: ''[[Robot of Sherwood]]'', ''[[Last Christmas (TV story)|Last Christmas]]'')
 
He also got excited when he was inside a Dalek, ([[TV]]: ''[[Into the Dalek]]'') enthusiastically tried to find out the cause of his childhood nightmares. ([[TV]]: ''[[Listen]]'') got giddy over possibly finding out the existence of ghosts, ([[TV]]: ''[[Under the Lake]]'') and was very eager to explore a mysterious house. ([[COMIC]]: ''[[Playing House (comic story)|Playing House]]'') [[Kevin Alperton]] noted that, while the Doctor looked old, he had an energy to him that made him seem younger and different. ([[PROSE]]: ''[[The Crawling Terror]]'')
 
[[File:Twelfth Doctor inside Aristotle.jpg|thumb|left|The Doctor's more wistful side manifests as he turns down [[Journey Blue]]. ([[TV]]: ''[[Into the Dalek]]'')]]
Even though he identified himself as a pacifist, ([[COMIC]]: ''[[Terrorformer (comic story)|Terrorformer]]'') and believed necessary evils to be a last resort, ([[COMIC]]: ''[[The Fractures (comic story)|The Fractures]]'') the Twelfth Doctor showed even less restraint than his predecessor, and would get frank and physical with his enemies. ([[TV]]: ''[[Deep Breath]]'', ''[[Hell Bent]]'') However, behind his cold exterior, he was extremely self-reflective, to the point where he even questioned whether he was a good man. ([[TV]]: ''[[Deep Breath]]'', ''[[Into the Dalek]]'', ''[[Flatline]]'') Clara also felt that "there were several layers to the Doctor's emotions." ([[PROSE]]: ''[[Silhouette (novel)|Silhouette]]'') The Doctor himself was well aware of the fact that he often found himself in situations that forced him to make terrible decisions, ([[PROSE]]: ''[[The Blood Cell]]''; [[TV]]: ''[[Mummy on the Orient Express]]'') and believed he was "overbearing, manipulative and consciously aware of his own intelligence". ([[TV]]: ''[[Time Heist]]'') Eventually, he came to the conclusion that he was neither a good nor bad man, but rather just "an idiot, with a box and a screwdriver, just passing through, helping out, [and] learning," ([[TV]]: ''[[Death in Heaven]]'') and later added that he was "just a bloke in a box telling stories". ([[TV]]: ''[[The Witch's Familiar]]'')
 
Though he retained a respect for humanity, the Doctor would insult humans as being close-minded and violent, dubbing [[Earth]] the "planet of the pudding-brains." ([[TV]]: ''[[Deep Breath]]'', ''[[The Caretaker]]'', ''[[Kill the Moon]]'', ''[[In the Forest of the Night]]'') Nonetheless, he tolerated the company of those who could engage him intellectually, ([[TV]]: ''[[Mummy on the Orient Express]]'', ''[[Death in Heaven]]'', ''[[Under the Lake]]'') unless they got on his bad side first, ([[COMIC]]: ''[[The Fractures (comic story)|The Fractures]]'') and claimed to respect humanity enough to allow it to determine its own future without any interference from him. ([[TV]]: ''[[Kill the Moon]]'')
 
As with his previous incarnation, the Twelfth Doctor also liked people who got straight to the point, and thought that someone who wasn't scared in a life-threatening situation was an idiot, ([[TV]]: ''[[Last Christmas (TV story)|Last Christmas]]'') and would have them focus on their chances of survival, however slim, to encourage them to prevail. ([[TV]]: ''[[The Magician's Apprentice]]'')
 
Though he did not know the reason, believing it to simply be his old age, ([[PROSE]]: ''[[The Blood Cell]]'') the Twelfth Doctor expressed a strong dislike for soldiers, ([[TV]]: ''[[Into the Dalek]]'', ''[[The Caretaker]]'') and was "decidedly prickly in his dealing with anything remotely military", ([[PROSE]]: ''[[The Crawling Terror]]'') though claimed his disdain was flexible in a crisis. ([[PROSE]]: ''[[The Blood Cell]]'') However, he showed sympathy towards Captain [[Quell]] and the [[Foretold]], ([[TV]]: ''[[Mummy on the Orient Express]]'') and still retained a respect for [[the Brigadier]]. ([[TV]]: ''[[Death in Heaven]]'') He was also easily annoyed by swashbucklers who did not take things seriously, ([[TV]]: ''[[Robot of Sherwood]]'') even abandoning a village of [[Viking]]s to death in battle due to their insistence on fighting the [[Mire]], ([[TV]]: ''[[The Girl Who Died]]'') and held a disdain towards businesspeople who valued profit above anything else. ([[TV]]: ''[[Under the Lake]]'', ''[[Sleep No More]]'') 
 
He also claimed to dislike liver, [[karaoke]], mime, ([[TV]]: ''[[Deep Breath]]'') [[babysitter]]s, ([[TV]]: ''[[Into the Dalek]]'') bantering, ([[TV]]: ''[[Robot of Sherwood]]'') ''[[Candy Crush]]'', ([[PROSE]]: ''[[The Blood Cell]]'') outside interference, [[money]], being taken prisoner, ([[COMIC]]: ''[[Terrorformer (comic story)|Terrorformer]]'') salutes, ([[TV]]: ''[[Death in Heaven]]'') [[pantomime]], ([[PROSE]]: ''[[Behind You (short story)|Behind You]]'') [[cyclops|cyclopes]], ([[COMIC]]: ''[[Doctor on the Menu (comic story)|Doctor on the Menu]]'') tanks, ([[TV]]: ''[[The Magician's Apprentice]]'') songs that got stuck in his head, ([[TV]]: ''[[Under the Lake]]'') [[Tivolian]]s, ([[TV]]: ''[[Before the Flood]]'') gardening, ([[TV]]: ''[[Heaven Sent]]'') [[pear]]s, ([[TV]]: ''[[Hell Bent]]'') [[Christmas]], ([[COMIC]]: ''[[Relative Dimensions (comic story)|Relative Dimensions]]'') "lying-down people", ([[TV]]: ''[[The Husbands of River Song]]'') and [[fish]]. ([[TV]]: ''[[Smile (TV story)|Smile]]'')
 
The Doctor had an extreme hatred of war, ([[TV]]: ''[[The Zygon Inversion]]'') even saying the word with contentment in his voice. ([[TV]]: ''[[The Magician's Apprentice]]'') When he learned that all [[Bonnie (The Zygon Invasion)|Bonnie]] truly wanted was a pointless war between humanity and the Zygons, he went into a furious and grief-stricken tirade by telling her that he knew what war was really like and that he would not allow her to lead others to their deaths. ([[TV]]: ''[[The Zygon Inversion]]'')
 
He also disliked being wrong in public, ([[TV]]: ''[[Deep Breath]]'') missing the obvious, ([[PROSE]]: ''[[Silhouette (novel)|Silhouette]]''; [[TV]]: ''[[Last Christmas (TV story)|Last Christmas]]'') and being sure of something. ([[TV]]: ''[[The Husbands of River Song]]'') While he claimed to hate not knowing about something when faced with [[The Teller (Time Heist)|the Teller]], ([[TV]]: ''[[Time Heist]]'') he was known to admire the unexplainable. ([[TV]]: ''[[Flatline]]'', ''[[Under the Lake]]'') He also told [[Ohila]] that, while he trusted her, he didn't necessary like her, ([[WC]]: ''[[Prologue (webcast)|Prologue]]'') and confessed to [[Osgood (The Day of the Doctor)|Osgood]] that, while he spent a lot of time there, he considered [[London]] to be a "dump". ([[TV]]: ''[[The Zygon Inversion]]'')
 
He did, however, like babies and [[bicycle]]s, which reminded him of ''[[Call the Midwife]]'', as well as [[star]]s, ([[PROSE]]: ''[[The Blood Cell]]'') [[candy floss]], ([[PROSE]]: ''[[All the Empty Towers (short story)|All the Empty Towers]]'') "a show-stopping entrance", ([[COMIC]]: ''[[Terrorformer (comic story)|Terrorformer]]'') a "good locked-room mystery", ([[TV]]: ''[[Flatline]]'') puppets, ([[TV]]: ''[[The Girl Who Died]]'') [[Sherbet|sherbet lemons]], [[Ferrari]] cars, ([[TV]]: ''[[The Woman Who Lived]]'') "poncing about in [[Boat One|a big plane]]", ([[TV]]: ''[[The Zygon Invasion]]'') and the title "Doctor Mysterio". ([[TV]]: [[The Return of Doctor Mysterio (TV story)|''The Return of Doctor Mysterio'']])
 
The Doctor had a liking for books, particular ones about ''[[Garfield]]'', reacting with anger towards those he believed burned books, and also believed that women who liked books to be the best kind. ([[PROSE]]: ''[[The Blood Cell]]'') When he redecorated the TARDIS control room, he included numerous shelves full of a variety of books, and a recliner to enjoy reading them in. ([[TV]]: ''[[Deep Breath]]'')
 
[[File:Doctordalekgun.jpg|thumb|left|The Doctor readies a [[gunstick]]. ([[TV]]: ''[[The Magician's Apprentice]]'')]]
While he disliked guns, he noted that it was foolish to disregard them when they were useful, ([[PROSE]]: ''[[The Crawling Terror]]'') and was willing to utilise one himself when he felt the need to, but would immediately discard it once it was no longer needed. ([[TV]]: ''[[The Witch's Familiar]]'', ''[[Hell Bent]]'')
 
While he did not dwell on the subject much, the Twelfth Doctor was still haunted by the [[War Doctor]]'s actions in the [[Last Great Time War]], and claimed to hear "more screams than anyone could ever be able to count" whenever he closed his eyes, and vowed that he would ensure that others would never have to feel the angst he felt. ([[TV]]: ''[[The Zygon Inversion]]'')
 
The Doctor also hoped to one day find [[Gallifrey]], and reacted with devastation when his hope of finding it turned out to be a false lead. ([[TV]]: ''[[Death in Heaven]]'') When he finally did manage to find his way to Gallifrey after enduring "4.5 billion years" of torture within his [[confession dial]], he first returned to his [[Barn (The Day of the Doctor)|old barn hideaway]] in the [[Drylands]], and then lead a [[coup against Rassilon]] to banish him and the [[High Council]] for their part in the Time War. After using the Time Lords technology to save Clara from the [[Quantum Shade]], the Doctor fled from Gallifrey once again. ([[TV]]: ''[[Hell Bent]]'')
 
[[File:Awkward Hug.jpg|thumb|right|The Doctor decides hugging isn't for him.  ([[TV]]: ''[[Deep Breath]]'')]]
Unlike his immediate predecessor, the twelfth incarnation was not an affectionate individual, failing to return Clara's hugs, or protesting against them, believing they were just another way to hide one's face, ([[TV]]: ''[[Deep Breath]]'', ''[[Listen]]'', ''[[Death in Heaven]]'') but claimed them a good way to smell someone's hair. ([[PROSE]]: ''[[The Blood Cell]]'') He also expressed a dislike of holding hands with others, but made an exception for Clara and [[Shona McCullough]]. ([[TV]]: ''[[Last Christmas (TV story)|Last Christmas]]'') He did, however, draw the line at performing a "high five" with Clara. ([[TV]]: ''[[Under the Lake (TV story)|Under the Lake]]'') However, he hugged Clara to comfort her after she was almost shot, ([[PROSE]]: ''[[The Blood Cell]]'') and again when they parted ways. ([[TV]]: ''[[Death in Heaven]]'') Over time, the Doctor began to accept Clara's attempts to hug him, ([[TV]]: ''[[Last Christmas (TV story)|Last Christmas]]'', ''[[The Woman Who Lived]]'', ''[[Face the Raven]]'') and even started hugging her on the odd occasion. ([[TV]]: ''[[The Magician's Apprentice]]'', ''[[The Girl Who Died]]'') By the time he reunited with [[Maxwell Edison]], the Doctor had accepted being a hugger, given an affection on to Max. ([[COMIC]]: ''[[The Stockbridge Showdown (comic story)|The Stockbridge Showdown]]'')
 
Uncomfortable with kissing, he was momentarily dumbfounded when [[Maid Marian]] pecked him on the cheek in gratitude for saving her, ([[TV]]: ''[[Robot of Sherwood]]'') and reacted with horror after he was passionately kissed by {{Gomez}}. ([[TV]]: ''[[Dark Water (TV story)|Dark Water]]'') However, he pecked Missy on the lips in gratitude for forcing him into self-reflection, ([[TV]]: ''[[Death in Heaven]]'') kissed Clara's forehead while complimenting her brilliance in a moment of excitement, ([[COMIC]]: ''[[The Big Hush (comic story)|The Big Hush]]'') gave [[Meghan (All the Empty Towers)|Meghan]], a donkey he had befriended, a kiss on the head when he thought no one was looking, ([[PROSE]]: ''[[All the Empty Towers (short story)|All the Empty Towers]]'') and kissed Clara's hand as a farewell gesture before she met her death. ([[TV]]: ''[[Face the Raven]]'') He also accepted kisses on the cheek from both Clara, ([[TV]]: ''[[Last Christmas (TV story)|Last Christmas]]'') and [[River Song]]. ([[TV]]: ''[[The Husbands of River Song]]'')
 
[[File:Deep Breath story image.jpg|thumb|left|The Doctor's piercing glare. ([[TV]]: ''[[Deep Breath]]'')]]
Though he initially stated that murder was against his "programming", the Doctor showed a willingness to kill the [[Half-Face Man]] if he had to, though with some reluctance, first offering him a drink of alcohol and trying to persuade the clockwork droid to self-destruct of his own free will before engaging in fisticuffs. ([[TV]]: ''[[Deep Breath]]'') He also stated that, despite how much he hated him, he had no intention of killing the Architect, ([[TV]]: ''[[Time Heist]]'') but was willing to kill {{Gomez}} to spare Clara from doing it. ([[TV]]: ''[[Death in Heaven]]'') He was also willing to kill the [[Fisher King]] by causing a flood and tricking the latter out into the open, where he was engulfed by the deluge, ([[TV]]: ''[[Before the Flood]]'') gave permission for UNIT to engage [[Zygon]]s with lethal force, so long as they kept fatalities to a minimum, ([[TV]]: ''[[The Zygon Invasion]]'') and fatally shot [[the General]] after being assured he would [[Regeneration|regenerate]]. ([[TV]]: ''[[Hell Bent]]'') He also released [[the Judge]] on a group of Guardians in an elaborate bid to gain their trust, resulting in the death of [[Chandress]], ([[PROSE]]: ''[[The Blood Cell]]'') orchestrated the deaths of two [[Kaliratha]] that were keeping him prisoner by taking them to a point in time prior to their bodies being discovered, ([[COMIC]]: ''[[The Swords of Kali (comic story)|The Swords of Kali]]'') and left [[Ron Cordell]] and some [[Skink]]s to be devoured by a [[black hole]] after tampering with the [[black hole drive]]'s containment field. ([[COMIC]]: ''[[Pirates of Vourakis (comic story)|Pirates of Vourakis]]'') He also viewed certain creatures as expendable, as he wanted to kill a [[dream crab]] to save Clara from slowly being devoured by it, ([[TV]]: ''[[Last Christmas (TV story)|Last Christmas]]'') and crushed a defenseless [[Love Sprite]] under his heel to prevent it attacking him. ([[TV]]: ''[[The Girl Who Died]]'') He also occasionally enacted violence against his TARDIS out of frustration, striking its column with his fists hard enough to damage it after discovering Missy's coordinates to Gallifrey had been a lie ([[TV]]: ''[[Death in Heaven]]'') and later struck the console with enough force for he to believe he had broken a finger. ([[PROSE]]: ''[[Deep Time (novel)|Deep Time]]'')
 
Unlike his immediate predecessor, the Twelfth Doctor was unwilling to alter the [[Web of Time]], fearing that the ramifications from the tiniest changes could be catastrophic, spreading "carnage and chaos across the universe like ripples on a pond," ([[TV]]: ''[[Before the Flood]]'') instead opting to create "ripples" instead of "tidal waves." ([[TV]]: ''[[The Girl Who Died]]'') He believed it was okay to send people to their deaths if history recorded them as deceased, ([[PROSE]]: ''[[The Crawling Terror]]'') and also refused Clara's request to save [[Danny Pink]] from being hit by a car due to it being a part of her timeline, and undoing it would cause a [[paradox]]. ([[TV]]: ''[[Dark Water (TV story)|Dark Water]]'') He also told [[Mason Bennett]] that he "[couldn't] just go back and cut off tragedy at the root, because you find yourself talking to someone you just saw dead on a slab, [and] then you really do see ghosts". ([[TV]]: ''[[Before the Flood]]'') However, upon returning to [[Gallifrey]], the Doctor used an [[extraction chamber]] to save Clara from the [[Quantum Shade]], and also attempted to prevent her from returning to her death, despite it being a [[fixed point in time]]. ([[TV]]: ''[[Hell Bent]]'')
 
Much like his [[Seventh Doctor|seventh]] and [[War Doctor|war incarnations]], the Twelfth Doctor was heavily inclined to err toward a greater good and was willing to allow a few inevitable deaths if it meant saving the majority. Through this attitude, he acted like a pragmatist that would not hesitate to abandon someone whose fate was already sealed, nor mourn for an ally until his objective had been reached. ([[TV]]: ''[[Into the Dalek]]'', ''[[Time Heist]]'', ''[[Kill the Moon]]'', ''[[Mummy on the Orient Express]]'', ''[[Sleep No More]]'') However, the Doctor was still willing to save people if their deaths were not an immediate inevitability, desperately yelling for people to flee from [[St. Paul's Cathedral]] when the [[Cyberman (Mondas)|Cybermen]] began their invasion, ([[TV]]: ''[[Dark Water (TV story)|Dark Water]]'') as well as attempting to save [[Albert Smithe]] from the [[Dream crab|Kantrofarri]], ([[TV]]: ''[[Last Christmas (TV story)|Last Christmas]]'') making a small effort to prevent [[Alice O'Donnell]] from being killed in [[Краснодар]], ([[TV]]: ''[[Before the Flood]]'') and making sure to prevent future colonists from being killed by the [[Vardy]]. ([[TV]]: ''[[Smile (TV story)|Smile]]'')
 
Also like his previous incarnations, he relied on his companions to keep him from succumbing to his darker nature, but, unlike his predecessors, the Twelfth Doctor actively praised them for it, even claiming that [[Clara Oswald]] needed a "raise" for dealing with him. ([[TV]]: ''[[Into the Dalek]]'') He also enjoyed it when they asked him obvious questions, claiming that it helped him think, ([[PROSE]]: ''[[The Blood Cell]]'') and identified them as his "social interface with the human race", ([[COMIC]]: ''[[The Fractures (comic story)|The Fractures]]'') and the main reason he didn't need an army. ([[TV]]: ''[[Death in Heaven]]'')
 
In stark contrast to his previous incarnations, the Twelfth Doctor was more willingly to leave a situation if he believed he had nothing to contribute; abandoning [[Jason Clearfield]] when he could not offer medical assistance, ([[PROSE]]: ''[[The Crawling Terror]]'') abandoning soldiers dying of diseases after solving the mystery of the source, ([[PROSE]]: ''[[Silver Mosquitoes (short story)|Silver Mosquitoes]]'') leaving Clara, [[Courtney Woods]] and Captain [[Lundvik]] to decide the fate of the Moon when he felt it wasn't his place to decide for them, ([[TV]]: ''[[Kill the Moon]]'') and leaving the [[North Pole]] base immediately after defeating the [[Dream crab]]s, despite Clara claiming the team was still in danger. ([[TV]]: ''[[Last Christmas (TV story)|Last Christmas]]'') The Doctor justified his attitude by pointing out the dangers of everyday life, claiming that "[everything is] dangerous if you want it to be", and once even pointed out to Clara that he was neither humanity's mother or the police. ([[TV]]: ''[[Kill the Moon]]'', ''[[Last Christmas (TV story)|Last Christmas]]'', ''[[The Girl Who Died]]'')
 
By his own testament, the Twelfth Doctor did not suffer fools gladly, ([[PROSE]]: ''[[The Blood Cell]]'') nor did he tolerate poor manners, even when held at gunpoint, and he believed that one should make requests politely, as well as avoid bad language. ([[TV]]: ''[[Into the Dalek]]'', ''[[Kill the Moon]]'') He had a consistently anti-authoritarian attitude, only ever asking who was in charge so he could know who to ignore. ([[TV]]: ''[[Under the Lake]]'') He also felt invasions of Earth were justified after hearing about the horror film ''[[Alien (film)|Alien]]'', ([[TV]]: ''[[Last Christmas (TV story)|Last Christmas]]'') and expressed the opinion that an enemy was "just a friend you didn't really know yet". ([[WC]]: ''[[Prologue (webcast)|Prologue]]'')
 
Despite his grumpy nature, the Doctor got along well with children, giving a big tip to a little girl selling matches, ([[PROSE]]: ''[[Silhouette (novel)|Silhouette]]'') giving [[Danny Pink|Rupert Pink]] an enthusiastic pep talk about fear being a super power, ([[TV]]: ''[[Listen]]'') comparing the TARDIS' dimensions to the sugar in a coke bottle for [[Maebh Arden]], while also telling her that her theory of everyone knowing everything but her was "not quite true", ([[TV]]: ''[[In the Forest of the Night]]'') helping [[Evie Hubbard]] with her history homework, ([[TV]]: ''[[The Woman Who Lived]]'') and stopping to tie a young boy's shoelaces while searching for a [[trap street]]. ([[TV]]: ''[[Face the Raven]]'') After realising he had hurt [[Courtney Woods]]'s feelings, he decided to take her and Clara to [[the Moon]], so that Courtney could be the first girl on the Moon, to help her feel special, ([[TV]]: ''[[Kill the Moon]]'') and was ashamed with himself when he abandoned a young [[Davros]] to the [[Handmine]]s, to the extend that he felt only death could atone for his actions. ([[TV]]: ''[[The Magician's Apprentice]]'') He also did not look down at children, and treated their thoughts and suggestions as seriously as he did with grown-ups' ideas and opinions. ([[TV]]: ''[[Listen]]'', ''[[In the Forest of the Night]]'', ''[[The Girl Who Died]]'')  and being very upset when he found a baby unattended too. ([[TV]]: [[The Return of Doctor Mysterio (TV story)|''The Return of Doctor Mysterio'']])
 
An absent minded incarnation, the Twelfth Doctor failed to notice when someone was asking him if they looked attractive, ([[TV]]: ''[[Into the Dalek]]'', ''[[Time Heist]]'', ''[[The Woman Who Lived]]'') would go off to a location without asking for directions, ([[PROSE]]: ''[[Silhouette (novel)|Silhouette]]'') had trouble recognising people's age group, ([[TV]]: ''[[Into the Dalek]]'', ''[[The Caretaker]]'', ''[[Kill the Moon]]'', ''[[Last Christmas (TV story)|Last Christmas]]'', [[The Return of Doctor Mysterio (TV story)|''The Return of Doctor Mysterio'']]) believed that minor clothing changes hid his identity, ([[TV]]: ''[[The Caretaker]]'') could not grasp the concept of an English lesson, ([[COMIC]]: ''[[The Fractures (comic story)|The Fractures]]'') and would read sentences in their entirety even when he didn't have to. ([[TV]]: ''[[Under the Lake]]'') Like his predecessor, he was also shown to have a poor concept on the passage of time. ([[TV]]: ''[[The Magician's Apprentice]]'', ''[[The Zygon Inversion]]'')
 
He would also make contradictory statements, such as telling [[Courtney Woods]] that she "wasn't special", ([[TV]]: ''[[Kill the Moon]]'') despite previously telling the [[Half-Face Man]] that humanity "never [seemed] small to [him]". ([[TV]]: ''[[Deep Breath]]'') He also claimed that Clara would hate the "smelly, dirty and dangerous" Arthurian era, but would love the [[Victorian era]] for the same reasons, ([[PROSE]]: ''[[Silhouette (novel)|Silhouette]]'') and claimed that, while he found the transmitter ghosts as "evil", he also found them "astonishing", and said he "want[ed] to kiss [them] to death". ([[TV]]: ''[[Under the Lake]]'') He called [[London]] a "cradle of culture", but later confessed to Osgood that he thought it a "dump". ([[TV]]: ''[[The Zygon Inversion]]'')
 
The Twelfth Doctor believed that education came quicker in life threating situations, and claimed that begging "wasn't [his] style", ([[COMIC]]: ''[[Terrorformer (comic story)|Terrorformer]]'') unless his friends were threatened, ([[COMIC]]: ''[[Spirits of the Jungle (comic story)|Spirits of the Jungle]]''; [[TV]]: ''[[The Magician's Apprentice]]'') or he was at a particularly dangerous risk of harm. ([[TV]]: ''[[The Witch's Familiar]]'') He also didn't care about [[sexuality]], instead being bothered by people hating each other, and didn't approve of revenge. ([[COMIC]]: ''[[The Swords of Kali (comic story)|The Swords of Kali]]'')
 
He had a more celibate nature than his predecessor; dismissing Clara's comments on [[Silhouette (Silhouette)|Silhouette]]'s attractiveness, ([[PROSE]]: ''[[Silhouette (novel)|Silhouette]]'') and not understanding Dr. [[Chang (Dark Water)|Chang]]'s suggestion about the application of [[dark water]] in public swimming pools. He also described Clara as being "a mess of chemicals" after she professed her love for [[Danny Pink]]. ([[TV]]: ''[[Dark Water (TV story)|Dark Water]]'') Despite this, he called a female [[Tyrannosaurus rex]] a "big sexy woman" while in a post-regenerative state, ([[TV]]: ''[[Deep Breath]]'') and considered [[Fiona Bellows]] "sexy", partially because of her Scottish accent, ([[TV]]: ''[[Last Christmas (TV story)|Last Christmas]]'') and shared a mutual attraction with [[River Song]]. ([[TV]]: ''[[The Husbands of River Song]]'')
 
He claimed that taking charge was his "superpower", ([[TV]]: ''[[Time Heist]]'') and listed "investigating", "playing with time" and "resistance" among his specialities, ([[COMIC]]: ''[[Terrorformer (comic story)|Terrorformer]]'', ''[[The Swords of Kali (comic story)|The Swords of Kali]]'', ''[[The Fractures (comic story)|The Fractures]]'') with Clara adding "interfering and infuriating" to the list. ([[COMIC]]: ''[[Terrorformer (comic story)|Terrorformer]]'')
 
After redecorating his console room, the Doctor designed it with a more lived-in state, filling it with bookshelves, chairs, and workbenches, ([[TV]]: ''[[Deep Breath]]'', ''[[The Caretaker]]'') and even once having a meal in it with guests. ([[TV]]: ''[[Time Heist (TV story)|Time Heist]]'') He once told Clara that the TARDIS was his house. ([[TV]]: ''[[Flatline]]'')
 
The Twelfth Doctor's hatred toward the [[Dalek]] species was rigid, with Clara describing it as "prejudice", ([[TV]]: ''[[Into the Dalek]]'') though he did stop to mourn [[Lumpy]], a Dalek that had deceived him into friendship. ([[GAME]]: ''[[The Doctor and the Dalek]]'') He believed Daleks were incapable of change and was closed-minded as he dealt with their presence, and would refuse to help a Dalek unless his interests were peaked. ([[TV]]: ''[[Into the Dalek]]''; [[GAME]]: ''[[The Doctor and the Dalek]]'') After his act of fixing a [[Rusty|malfunctioning "good" Dalek]] caused it to revert to "evil", the Doctor was almost pleased that his belief of there being "no such thing as a good Dalek" was vindicated. ([[TV]]: ''[[Into the Dalek]]'') Despite his hatred of them, the Doctor admitted to [[Governor (The Blood Cell)|the Governor]] that the [[Dalek Emperor]] "[was] nothing compared to your average mobile phone sales assistant". ([[PROSE]]: ''[[The Blood Cell]]'') He also held a disregard for the [[Cyberman (Mondas)|Cybermen]], unceremoniously flattening two with his TARDIS. ([[GAME]]: ''[[The Doctor and the Dalek]]'')
 
Additionally, the Twelfth Doctor was, at times, critical of his previous incarnations' clothing; thinking that his [[Fourth Doctor|fourth incarnation]]'s [[The Doctor's scarf|scarf]] "looked stupid", ([[TV]]: ''[[Deep Breath]]'') and regarded his immediate predecessor's fondness for [[bow tie]]s as "a bit embarrassing", ([[TV]]: ''[[Time Heist]]'') but complimented Osgood's bow tie as "nice". ([[TV]]: ''[[Death in Heaven]]'') According to [[Affinity]], the Doctor kept his predecessors "lodged in his head", and held a low opinion of them and himself. ([[PROSE]]: ''[[Silhouette (novel)|Silhouette]]'')
 
[[File:Four Doctors The Photo.jpg|thumb|The Doctor argues with his past selves. ([[COMIC]]: ''[[Four Doctors (comic story)|Four Doctors]]'')]]
When he met his two previous incarnations, he had a frosty accord with the [[Tenth Doctor]], who refused to consider the twelfth incarnation as a future incarnation until the [[Blinovitch Limitation Effect]] confirmed he was. Conversely, the Eleventh Doctor was willing to accept him as his next incarnation and was happy to know he had more life in the future. The Twelfth Doctor, however, expressed concern that the two would come to know him as the "scary Doctor". He held the [[Ninth Doctor]] in higher regards, saying the Continuity Bomb could not find an timeline where he wasn't "fantastic". ([[COMIC]]: ''[[Four Doctors (comic story)|Four Doctors]]'')
 
He disliked his [[Eleventh Doctor|immediate predecessor]] for his enjoyment of bow ties and [[fez]]zes, and overuse of the word "cool". ([[COMIC]]: ''[[Terrorformer (comic story)|Terrorformer]]'') However, upon seeing [[Adrian Davies]], a teacher at [[Coal Hill School]] with a resemblance to his previous incarnation, the Doctor, mistaking Adrian as Clara's boyfriend, arrogantly assumed that Clara was dating Adrian because of his uncanny resemblance to "a certain dashing young time traveller", reflecting more favourably on his predecessor. ([[TV]]: ''[[The Caretaker]]'')
 
When [[Rusty]] the [[Dalek]] looked into the Twelfth Doctor's mind, he saw hatred and noted that the Doctor was "a good Dalek", while Clara believed the Doctor was trying to be a good man regardless, ([[TV]]: ''[[Into the Dalek]]'') and claimed that he "always care[d]" by the time of her death. ([[TV]]: ''[[Face the Raven]]'') [[Perkins (Mummy on the Orient Express)|Perkins]] noted his inability to decide whether the Doctor was a genius "or just incredibly arrogant". ([[TV]]: ''[[Mummy on the Orient Express]]'') [[Danny Pink]], in complete bitterness for his need to feel the pain he inflicted, compared the Doctor to a "blood-soaked old general". ([[TV]]: ''[[Death in Heaven]]'')
 
[[The Oracle (The Blood Cell)|The Oracle]] described the Twelfth Doctor as "a man of taste and discrimination," ([[PROSE]]: ''[[The Blood Cell]]'') while [[Orestes Milton]] believed the Doctor "affect[ed] an air of ignorance and indifference, but beneath it [were] undercurrents of knowledge and curiosity". ([[PROSE]]: ''[[Silhouette (novel)|Silhouette]]'')
 
Both [[Clara Oswald]] and [[Kate Stewart]] viewed the Twelfth Doctor as an egotist. ([[TV]]: ''[[Robot of Sherwood]]''; [[COMIC]]: ''[[The Fractures (comic story)|The Fractures]]'') However, when questioned by [[Lisa Foster]], Clara reluctantly admitted she thought the Doctor was "kind of [cool]. In a strange sort of way", which Lisa interpreted as meaning "an uncool sort of way". ([[COMIC]]: ''[[The Fractures (comic story)|The Fractures]]'')
 
Much as his [[Tenth Doctor|tenth incarnation]] expressed, the Twelfth Doctor associated [[regeneration]] with death, recalling [[Snowcap]] as "the place where [[First Doctor|he]] died". He viewed the process as "huge, [and] terrible", with his self-preservation preventing his memories of the experience from consuming him. ([[COMIC]]: ''[[Blood and Ice (comic story)|Blood and Ice]]'') He also believed that regeneration was to be used only when completely necessary, and to use it to fix a broken toe was "a waste of a life". ([[PROSE]]: ''[[The Blood Cell]]'') Despite his beliefs, he was willing to force a fellow Time Lord to regenerate if he had to. ([[TV]]: ''[[Hell Bent]]'')
 
When faced with the prospect of dying without regenerating while facing the [[Fisher King]], the Doctor, though initially appearing distraught, quickly dismissed any concern, saying that he "had a good innings", and labeling himself a mere "clerical error" of a regeneration, telling Clara that "we all have to face death eventually, be it ours or someone else's." ([[TV]]: ''[[Before the Flood]]'') When cornered by the [[Veil (Heaven Sent)|Veil]], the Doctor admitted that he was afraid of dying. ([[TV]]: ''[[Heaven Sent]]'')
 
=== Habits and quirks ===
Much like his [[Seventh Doctor|seventh incarnation]], the Twelfth Doctor spoke with a [[Scottish]] accent, ([[TV]]: ''[[Deep Breath]]'') which was noted by [[Bernice Summerfield]] to be [[Glaswegian]] in contrast to the Seventh Doctor's [[Highlands]] one. ([[PROSE]]: ''[[Big Bang Generation (novel)|Big Bang Generation]]'') He took his Scottish accent as an entitlement to complain about things, ([[TV]]: ''[[Deep Breath]]'') and found attractive in others. ([[TV]]: ''[[Last Christmas (TV story)|Last Christmas]]'') With his accent, he was prone to making subtle or climactic boasts. ([[TV]]: ''[[Deep Breath]]'', ''[[Into the Dalek]]'', ''[[Robot of Sherwood]]'', ''[[Mummy on the Orient Express]]'', ''[[Flatline]]'', ''[[The Magician's Apprentice]]'', ''[[The Witch's Familiar]]'', ''[[Before the Flood]]'', ''[[The Girl Who Died]]'', ''[[Face the Raven]]'', ''[[Heaven Sent]]'', [[The Return of Doctor Mysterio (TV story)|''The Return of Doctor Mysterio'']]) When truly angered, the Doctor, instead of shouting, would hiss with quiet rage. ([[TV]]: ''[[Dark Water (TV story)|Dark Water]]'', ''[[Face the Raven]]'', ''[[Hell Bent]]'')
 
When proposing a theory, the Doctor would use words such as "question" or "proposition", and would begin his conclusion with "answer", "conjecture" or "conclusion". ([[TV]]: ''[[Deep Breath]]'', ''[[Listen]]'', ''[[Time Heist]]'', ''[[The Witch's Familiar]]'') After working out the important questions in his head, he waited for others to come to the same conclusion, becoming increasingly annoyed with each wrong question or answer they proposed. ([[TV]]: ''[[Deep Breath]]'', ''[[In the Forest of the Night]]'', ''[[Last Christmas (TV story)|Last Christmas]]'', ''[[Under the Lake]]'', ''[[Sleep No More]]'')
 
When in a moment of realisation or thinking intensely, the Doctor would often tell people to "shut up", regardless if others would be speaking or not. ([[TV]]: ''[[Deep Breath]]'', ''[[Listen]]'', ''[[Time Heist]]'', ''[[The Caretaker]]'', ''[[Face the Raven]]'') He would also issue the instruction to those who had earned his ire, regardless of their status, occupation or how petty the ire was, ([[PROSE]]: ''[[The Blood Cell]]''; [[TV]]: ''[[Death in Heaven]]'', [[The Return of Doctor Mysterio (TV story)|''The Return of Doctor Mysterio'']]) and when he wished to avoid a subject of conversation. ([[TV]]: ''[[Dark Water (TV story)|Dark Water]]'', ''[[Last Christmas (TV story)|Last Christmas]]'')
 
Like the [[Ninth Doctor]] labeling humanity as "stupid apes", the Twelfth Doctor would call them "[[pudding-brain]]s", or "pudding head", when he found them slow-minded or stupid. ([[TV]]: ''[[Deep Breath]]'', ''[[Robot of Sherwood]]'', ''[[Flatline]]'') He would also accuse things, even other people, of developing faults and errors when he didn't think they were working the way he though they were meant to. ([[TV]]: ''[[Deep Breath]]'', ''[[Listen]]'', ''[[The Caretaker]]'', ''[[Dark Water (TV story)|Dark Water]]'')
 
Like his ninth and eleventh incarnations, the Doctor often used "hell" as an intensive. ([[TV]]: ''[[Dark Water (TV story)|Dark Water]]'', ''[[The Girl Who Died]]'', ''[[The Zygon Inversion]]'', ''[[Face the Raven]]'', ''[[Heaven Sent]]'', ''[[Hell Bent]]'')
 
The Doctor often made puns, ([[TV]]: ''[[Into the Dalek]]'', ''[[Kill the Moon]]'', ''[[Flatline]]'', ''[[The Magician's Apprentice]]'', ''[[The Witch's Familiar]]'', ''[[The Zygon Inversion]]'', ''[[The Husbands of River Song]]'') utilised a specific set of words, ([[COMIC]]: ''[[Terrorformer (comic story)|Terrorformer]]'', ''[[The Fractures (comic story)|The Fractures]]'') or quoted classic fairytales, ([[COMIC]]: ''[[The Eye of Torment (comic story)|The Eye of Torment]]'', ''[[The Swords of Kali (comic story)|The Swords of Kali]]''; [[TV]]: ''[[The Caretaker]]'') and song lyrics. ([[PROSE]]: ''[[The Blood Cell]]'', ''[[Silhouette (novel)|Silhouette]]''; [[TV]]: ''[[The Magician's Apprentice]]'', ''[[Sleep No More]]'')
 
[[File:Twelve Drink.jpg|thumb|left|The Doctor offers [[Half-Face Man]] a drink of whisky. ([[TV]]: ''[[Deep Breath (TV story)|Deep Breath]]'')]]
Unlike his first and eleventh incarnations, the Twelfth Doctor had a tolerance for alcoholic beverages. ([[TV]]: ''[[Deep Breath]]'', ''[[Time Heist]]'', ''[[Mummy on the Orient Express]]'') Much like his [[Third Doctor|third]] and [[Eighth Doctor|eighth incarnations]], he took his tea with extra sugar. ([[TV]]: ''[[Death in Heaven]]'')
 
Much like his predecessor, the Twelfth Doctor also used hand gestures to extenuate a point, but applied more dedication to his movements, standing firm, while speaking with conviction, and punctuating his points across with a pointed index finger, though would become more spontaneous when thinking intensely. ([[TV]]: ''[[Deep Breath]]'', ''[[Listen]]'', ''[[Time Heist]]'', ''[[The Caretaker]]'') Commonly, when his arms were stretched out, he would stick out his index and baby fingers with his thumb, and lower his middle and ring fingers. ([[TV]]: ''[[Deep Breath]]'', ''[[Into the Dalek]]'', ''[[Listen]]'', ''[[Time Heist]]'', ''[[The Caretaker]]'', ''[[Kill the Moon]]'', ''[[Dark Water (TV story)|Dark Water]]'', ''[[Last Christmas (TV story)|Last Christmas]]'', ''[[The Doctor's Meditation]]'', ''[[The Magician's Apprentice]]'', ''[[The Witch's Familiar]]'', ''[[Under the Lake]]'', ''[[Before the Flood]]'', ''[[Hell Bent]]'')
 
He was also known to bite down on his hand, ([[TV]]: ''[[Deep Breath]]'', ''[[Into the Dalek]]'', ''[[The Girl Who Died]]'', ''[[The Woman Who Lived]]'') tap his teeth with his finger, ([[PROSE]]: ''[[The Blood Cell]]''; [[TV]]: ''[[Kill the Moon]]'', ''[[Last Christmas (TV story)|Last Christmas]]'') or cradle his chin in his hand when thinking, ([[PROSE]]: ''[[Silhouette (novel)|Silhouette]]''; [[TV]]: ''[[Listen]]'', ''[[In the Forest of the Night]]'', ''[[Death in Heaven]]'', ''[[The Witch's Familiar]]'', ''[[The Girl Who Died]]'', ''[[Hell Bent]]'') and interlock his fingers when explaining or contemplating something. ([[TV]]: ''[[Into the Dalek]]'', ''[[Robot of Sherwood]]'', ''[[Time Heist]]'', ''[[The Caretaker]]'', ''[[Kill the Moon]]'', ''[[Mummy on the Orient Express]]'', ''[[In the Forest of the Night]]'', ''[[Dark Water (TV story)|Dark Water]]'', ''[[Last Christmas (TV story)|Last Christmas]]'', ''[[The Zygon Invasion]]'', ''[[Face the Raven]]'', ''[[Hell Bent]]'', ''[[The Husbands of River Song]]'')
 
Much like his fifth and sixth incarnations, he would also flick his jacket back and have his hands in his pockets, ([[TV]]: ''[[Deep Breath]]'', ''[[Into the Dalek]]'', ''[[The Caretaker]]'', ''[[Flatline]]'', ''[[Last Christmas (TV story)|Last Christmas]]'', ''[[Under the Lake]]'', ''[[Before the Flood]]'', ''[[The Girl Who Died]]'', ''[[The Woman Who Lived]]'', ''[[The Zygon Inversion]]'', ''[[Sleep No More]]'', ''[[Heaven Sent]]'', [[The Return of Doctor Mysterio (TV story)|''The Return of Doctor Mysterio'']]) and, like his second incarnation, often wringed his hands together, ([[TV]]: ''[[The Doctor's Meditation]]'', ''[[The Witch's Familiar]]'', ''[[Under the Lake]]'', ''[[Before the Flood]]'', ''[[The Girl Who Died]]'', ''[[The Woman Who Lived]]'', ''[[The Zygon Inversion]]'', ''[[Face the Raven]]'', ''[[Heaven Sent]]'') or twiddled his thumb in his hand. ([[TV]]: ''[[The Husbands of River Song]]'')
 
He also occasionally folded his arms like his ninth incarnation, ([[TV]]: ''[[Into the Dalek]]'', ''[[Listen]]'', ''[[The Caretaker]]'', ''[[The Girl Who Died]]'', ''[[The Husbands of River Song]]'') would rest his knuckles on his hips like his third incarnation, ([[TV]]; ''[[Mummy on the Orient Express]]'', ''[[Flatline]]'', ''[[Heaven Sent]]'') held his arms behind his back like his war incarnation, ([[TV]]: ''[[Before the Flood]]'', ''[[The Woman Who Lived]]'', ''[[The Zygon Invasion]]'', ''[[The Zygon Inversion]]'') and once mimicked his [[First Doctor|first incarnation]]'s habit of holding his lapels in an attempt to order others around, much to the annoyance of the [[Tenth Doctor]]. ([[COMIC]]: ''[[Four Doctors]]'')
 
When brooding in the TARDIS, the Doctor would lean on the console with his hand on his face as he looked downwards. ([[TV]]: ''[[Into the Dalek]]'', ''[[Death in Heaven]]'')
 
The Doctor made a habit of assigning nicknames to others, giving them names based on their appearance, by an accessory they carried or by their profession, ([[TV]]: ''[[Deep Breath]]'', ''[[Into the Dalek]]'', ''[[The Caretaker]]'') owing to the fact he often chose to forget people, ([[TV]]: ''[[Last Christmas (TV story)|Last Christmas]]'') or didn't have time to remember individual names, ([[TV]]: ''[[The Girl Who Died]]'') and would insist on addressing them as their nickname, such as calling [[Danny Pink]] "P.E.", despite Danny being a Maths teacher, due to seeing him as more a PE teacher than Maths, ([[TV]]: ''[[The Caretaker]]'', ''[[In the Forest of the Night]]'', ''[[Death in Heaven]]'') though he dropped the nickname after Danny died. ([[TV]]: ''[[Dark Water (TV story)|Dark Water]]'', ''[[Last Christmas (TV story)|Last Christmas]]'') He also continued to address [[Rigsy]] as "Local Knowledge" when he was standing in front of him, ([[TV]]: ''[[Flatline]]'') and when they reunited years later, only dropping the nickname when he learned Rigsy would die. ([[TV]]: ''[[Face the Raven]]'')
 
When not out adventuring, the Doctor could be found jotting down equations and theories on various chalkboards in the [[TARDIS console room]], ([[TV]]: ''[[Robot of Sherwood]]'', ''[[Listen]]'') or on hard surfaces that could bear chalk markings. ([[TV]]: ''[[Deep Breath]]'', ''[[The Doctor's Meditation]]'')
 
The Doctor would occasionally offer out [[Jelly baby|jelly babies]] in a similar way to the [[Fourth Doctor]], but, unlike his fourth incarnation, the Twelfth Doctor kept his jelly babies in a cigarette case. ([[TV]]: ''[[Mummy on the Orient Express]]''; [[COMIC]]: ''[[The Swords of Kali (comic story)|The Swords of Kali]]'') Also like his fourth incarnation, the Doctor would talk aloud to himself, ([[TV]]: ''[[Listen]]'', ''[[Mummy on the Orient Express]]'', ''[[Under the Lake]]'', ''[[Heaven Sent]]'') and was even known to [[Fourth wall|act like his was talking to someone]] when there was no evidence of him having company. ([[TV]]: ''[[Listen]]'', ''[[Before the Flood]]'') He also utulised a [[yo-yo]] on occasion. ([[TV]]: ''[[Kill the Moon]]'', ''[[The Girl Who Died]]'')
 
When in deep contemplation, the Doctor would meditate on the matter at hand, though, if he found the subject unsettling, he would try to avoid the mediation completely. ([[TV]]: ''[[Listen]]'', ''[[The Doctor's Meditation]]'')
 
Upon seeing a vase of picked flowers, the Doctor would grab a few and smell them, holding them right up to his nose. ([[TV]]: ''[[Deep Breath]]'', ''[[Death in Heaven]]'', ''[[Heaven Sent]]'')
 
Much like his fourth and ninth incarnations, the Twelfth Doctor would grin when he was pleased or amused, flashing his upper teeth as he smiled. ([[TV]]: ''[[Deep Breath]]'', ''[[Robot of Sherwood]]'', ''[[Listen]]'', ''[[Time Heist]]'', ''[[Kill the Moon]]'', ''[[Mummy on the Orient Express]]'', ''[[Death in Heaven]]'', ''[[The Witch's Familiar]]'', ''[[Under the Lake]]'', ''[[Before the Flood]]'', ''[[The Girl Who Died]]'', ''[[The Zygon Inversion]]'', ''[[Sleep No More]]'', ''[[Heaven Sent]]'', ''[[The Husbands of River Song]]'')
 
He kept a spare [[sonic screwdriver]] in case something happened to his first. ([[PROSE]]: ''[[Big Bang Generation (novel)|Big Bang Generation]]'') Even after he discarded his old screwdriver for a pair of [[sonic sunglasses]], ([[TV]]: ''[[The Magician's Apprentice]]'', ''[[The Witch's Familiar]]'') he still carried a model of his screwdriver to use on the odd occasion, ([[COMIC]]: ''[[The Ministry of Time (comic story)|The Ministry of Time]]'', ''[[The Dragon Lord (comic story)|The Dragon Lord]]'') after Clara returned one of his old spares to him. ([[COMIC]]: ''[[Clara Oswald and the School of Death (comic story)|Clara Oswald and the School of Death]]'') After receiving a new sonic screwdriver, he began to use them in conjunction with the sonic sunglasses. ([[TV]]: ''[[The Husbands of River Song]]'')
 
Some time after his travels with [[Sonny Robinson]] and [[Val Kent]], ( [[COMIC]]: ''[[Beneath the Waves (comic story)|Beneath the Waves]]'') the Twelfth Doctor started keeping a snack with him whenever he went out. (TV: ''[[The Return of Doctor Mysterio (TV story)|The Return of Doctor Mysterio]]'')
 
=== Skills ===
Highly observant, the Doctor was able to point out certain individuals in a crowd, ([[TV]]: ''[[Deep Breath]]'', ''[[The Magician's Apprentice]]'', ''[[The Woman Who Lived]]'') notice when someone near him was acting suspicious, ([[TV]]: ''[[Deep Breath]]'', ''[[The Caretaker]]'', ''[[Dark Water (TV story)|Dark Water]]'') and pick up on details that helped him unearth others' deceptions. ([[TV]]: ''[[Listen]]'') However, when his attention was focused, certain things around him would go amiss. ([[TV]]: ''[[Dark Water (TV story)|Dark Water]]'', ''[[The Husbands of River Song]]'')
 
[[File:Foretold_Approaches_Twelve.jpg|thumb|The Doctor faces the Foretold's riddle. ([[TV]]: ''[[Mummy on the Orient Express (TV story)|Mummy on the Orient Express]]'')]]
He was also able to make accurate [[deduction]]s from observing his surroundings, identifying the ''[[Aristotle (spaceship)|Aristotle]]'' as a medical ship within seconds of being on board, ([[TV]]: ''[[Into the Dalek]]'') noticing that [[Orestes Milton]] was a time traveller due to his choice of words and understanding of [[origami]], ([[PROSE]]: ''[[Silhouette (novel)|Silhouette]]'') solving the riddle of the [[Foretold]] within sixty-six seconds, ([[TV]]: ''[[Mummy on the Orient Express]]'') and calculating a length of time by placing his finger in a cup of [[coffee]]. ([[TV]]: ''[[Under the Lake]]'') He could also correctly [[deduce]] other's histories and how they felt in their environments from sheer observation, as with [[Anderson (Silhouette)|Anderson]], ([[PROSE]]: ''[[Silhouette (novel)|Silhouette]]'') and [[Quell|Captain Quell]]. ([[TV]]: ''[[Mummy on the Orient Express]]'') He also easily saw through the ruse of a conman's coin trick, boasting he could do better, which he did in discreetly stealing several of the man's pies. He subsequently used the coin trick to best Nardole in their dispute. ([[TV]]: ''[[Thin Ice (TV story)|Thin Ice]]'')
 
The twelfth incarnation retained his [[Eleventh Doctor|predecessor]]'s ability to converse with other species, such as [[dinosaur]]s, [[horse]]s, ([[TV]]: ''[[Deep Breath]]'') [[donkey]]s, ([[PROSE]]: ''[[All the Empty Towers (short story)|All the Empty Towers]]'') and [[Baby (language)|babies]]. ([[TV]]: ''[[The Girl Who Died]]'') Though he claimed his knowledge of [[British Sign Language]] had been replaced with [[semaphore]], he was still capable of signing, just not knowing what he had signed translated into. ([[TV]]: ''[[Under the Lake]]'') The Doctor also had a good sense of smell, which he used to assess his surroundings to [[deduce]] the time period he was in, ([[COMIC]]: ''[[The Swords of Kali (comic story)|The Swords of Kali]]'') which he could also do by putting his finger in the wind. ([[TV]]: ''[[Before the Flood]]'', ''[[Sleep No More]]'')
 
Strong and durable, the Doctor was able to upstage [[Michael Smith]] by easily holding two baskets of rocks, ([[PROSE]]: ''[[Silhouette (novel)|Silhouette]]'') force a door open with his shoulder, ([[PROSE]]: ''[[The Crawling Terror]]'') and smash up the [[TARDIS console]] with his bare hands in a grief-stricken rage. ([[TV]]: ''[[Death in Heaven]]''). Similar to his [[Ninth Doctor|ninth incarnation]], he wasn't afraid to use force, being a capable fighter, evidenced by how he was able to briefly support his weight single-handedly, ([[TV]]: ''[[Deep Breath]]'', ''[[Listen]]'') wrestle the Half-Face Man into a corner, ([[TV]]: ''[[Deep Breath]]'') withstand several blows from [[Abesse]], ([[PROSE]]: ''[[The Blood Cell]]'') stun [[the General]] with a single punch to the face. ([[TV]]: ''[[Hell Bent]]'') and knock down Sutcliffe by striking his face. ([[TV]]: ''[[Thin Ice (TV story)|Thin Ice]]''). Such prowess caused both the Half-Face Man and [[Kali]] to remark that the Doctor was stronger than he looked. ([[TV]]: ''[[Deep Breath]]''; [[COMIC]]: ''[[The Swords of Kali (comic story)|The Swords of Kali]]'') He was also capable of repeatedly striking a wall of [[Azbantium]] with his fists, even after breaking every bone in his hand, and was still able to use said hand to pull a lever afterwards. ([[TV]]: ''[[Heaven Sent]]'') He wasn't always so skilled though, being outmatched by his [[Twelfth Doctor (Four Doctors)|alternate self]] in a fight. ([[PROSE]]: ''[[Four Doctors (comic story)|Four Doctors]]'')
 
Like several of his predecessors, the Twelfth Doctor was a highly proficient swordsman, able to best [[Robin Hood]] in a duel using a spoon, ([[TV]]: ''[[Robot of Sherwood]]'') take on Kali's three swords with a single blade, ([[COMIC]]: ''[[The Swords of Kali (comic story)|The Swords of Kali]]'') and reportedly bested [[Bors (The Doctor's Meditation)|Bors]]' broadsword with a daffodil. ([[TV]]: ''[[The Magician's Apprentice]]'') He was also skilled in [[Venusian aikido]], using it to disarm a distracted [[Robin Hood]] and defend himself from Abesse. ([[TV]]: ''[[Robot of Sherwood]]''; [[PROSE]]: ''[[The Blood Cell]]'') Even without his Venusian aikido, the Doctor proved to be skilled in unarmed combat, ([[TV]]: ''[[Deep Breath]]''; [[COMIC]]: ''[[The Swords of Kali (comic story)|The Swords of Kali]]'') and possessed lightning-fast reflexes. ([[PROSE]]: ''[[The Crawling Terror]]'') notably able to turn and catch [[Spider (Thin Ice)|Spider's]] wrist as he tried to steal the sonic. ([[TV]]: ''[[Thin Ice (TV story)|Thin Ice]]'') He was also proficient with a [[Gunstick]], being able to shoot several [[Handmine]]s from a distance while also avoiding hitting [[Davros]]. ([[TV]]: ''[[The Witch's Familiar]]'')
 
Despite initially forgetting how to pilot his TARDIS due to post-regenerative trauma, ([[TV]]: ''[[The Time of the Doctor]]'') the Doctor soon mastered his way around the [[TARDIS console]], being able to save [[Journey Blue]] by piloting the TARDIS around her before her ship exploded, ([[TV]]: ''[[Into the Dalek]]'') materialise around Clara while she was drifting in space, ([[TV]]: ''[[The Girl Who Died]]'') and, with some difficulty, slowly fly the TARDIS above [[London]]. ([[TV]]: ''[[Face the Raven]]'') He also successfully returned Clara home in time for her dates, ([[TV]]: ''[[Listen]]'', ''[[The Caretaker]]'') though still made the occasional slip in timing and location. ([[TV]]: ''[[Deep Breath]]'', ''[[Into the Dalek]]'', ''[[Kill the Moon]]'', ''[[Death in Heaven]]'') He was also able to ride a horse, even when in a delirious post-regenerative state. ([[TV]]: ''[[Deep Breath]]'', ''[[The Woman Who Lived]]'')
 
Like his previous incarnations, the Twelfth Doctor also displayed telepathic abilities, being able to link his mind with [[Rusty]] to try and show the Dalek the beauty of the universe, ([[TV]]: ''[[Into the Dalek]]'') clear the Governor's thoughts by tapping him on the head, telepathically communicate with [[Marianne Globus]] by placing his hands on her template, ([[PROSE]]: ''[[The Blood Cell]]'') put [[Rupert Pink]] to sleep by placing his index finger on his forehead, editing his memories while he did so, ([[TV]]: ''[[Listen]]'') put Clara through a telepathic scenario with the aid of a [[Mood drug|sleep patch]], ([[TV]]: ''[[Dark Water (TV story)|Dark Water]]'') send a sedated Clara messages on blackboards by holding her hand, ([[TV]]: ''[[Last Christmas (TV story)|Last Christmas]]'') and establish a [[psychic link]] with a door to unlock it. ([[TV]]: ''[[Heaven Sent]]'')
 
A credited escapologist, ([[TV]]: ''[[The Girl Who Died]]'') the Doctor boasted at teaching [[Harry Houdini]] "everything he [knew]", ([[COMIC]]: ''[[The Swords of Kali (comic story)|The Swords of Kali]]'') and was repeatedly able to escape from his cell at [[the Prison]]. ([[PROSE]]: ''[[The Blood Cell]]'') He was also a talented gambler, winning $800,000 in less than an hour, which he credited to simple mathematics, ([[COMIC]]: ''[[Gangland (comic story)|Gangland]]'') and dancer, with Clara noting that he could apply for ''[[Strictly Come Dancing]]''. ([[COMIC]]: ''[[Trust (comic story)|Trust]]'')
 
Despite denying being a doctor of medicine, ([[PROSE]]: ''[[Silhouette (novel)|Silhouette]]'') the Doctor possessed at least a limited medical knowledge, being able to resuscitate [[Lafcardio]] with [[CPR|artificial resuscitation]] after Lafcardio's lungs were filled up with soot, with the Governor noting that the Doctor worked on Lafcardio like an expert. ([[PROSE]]: ''[[The Blood Cell]]'') He was also able to perform an accurate post-mortem on [[Michael Smith]], ([[PROSE]]: ''[[Silhouette (novel)|Silhouette]]'') and [[Alan Travers]]. ([[PROSE]]: ''[[The Crawling Terror]]'')
 
As cunning as his seventh incarnation, the Doctor was able to spin a fatal outcome into an advantage, such as using [[Ross (Into the Dalek)|Ross]]'s death to help him, Clara, Journey and [[Gretchen Carlisle]] escape [[Dalek antibody|Rusty's antibodies]], ([[TV]]: ''[[Into the Dalek]]'') using the deaths of [[Emile Moorhouse]] and Captain [[Quell]] as an opportunity to figure out a way to defeat the [[Foretold]], ([[TV]]: ''[[Mummy on the Orient Express]]'') and even using his own death to help him escape his [[confession dial]]. ([[TV]]: ''[[Heaven Sent]]'') He was also able to organise a bank heist to save [[The Teller (Time Heist)|the Teller]] and its mate, even erasing his planning of the heist to guarantee success. ([[TV]]: ''[[Time Heist]]'')
 
The Doctor could not only perform eye-fixation hypnotism with verbal commands, but he claimed that, as a [[Time Lord]], he could perform hypnosis that effected all the senses. ([[COMIC]]: ''[[Trust (comic story)|Trust]]'') He also threatened to use hypnotism to erase [[Danny Pink]]'s memory of the [[Skovox Blitzer]]. ([[TV]]: ''[[The Caretaker]]'')
 
Like his [[Third Doctor|third incarnation]], the Twelfth Doctor was a skilled inventor, being able to create an electron magnet and a sonic spoon in [[the Prison]]'s craft workshop, ([[PROSE]]: ''[[The Blood Cell]]'') a communication device to order a [[Skovox Blitzer]] to deactivate itself, ([[TV]]: ''[[The Caretaker]]'') a [[2Dis]] to combat the [[Boneless]], ([[TV]]: ''[[Flatline]]'') and rebuilding the TARDIS' radio into a clockwork squirrel. ([[TV]]: ''[[Under the Lake]]'')
 
Believing himself to be a good magician, ([[TV]]: ''[[The Doctor's Meditation]]'') the Doctor could hide objects in others' pockets, ([[PROSE]]: ''[[Silhouette (novel)|Silhouette]]'') swipe things without detection, ([[TV]]: ''[[Listen]]'') and also practiced coin magic. ([[TV]]: ''[[The Doctor's Meditation]]'') He was also able to swipe the General's sidearm before the General could regain his senses from being punched, ([[TV]]: ''[[Hell Bent]]'') and carry a glass of water in his pickets on skill alone. ([[TV]]: [[The Return of Doctor Mysterio (TV story)|''The Return of Doctor Mysterio'']])
 
After being thrown out of [[Boat One]] in an explosion, the Doctor was able to skydive towards his descending TARDIS, even fighting against the wind currents to place the [[TARDIS key]] into the lock. ([[TV]]: ''[[Death in Heaven]]'')
 
Despite believing his current incarnation to not be suited to the task, ([[PROSE]]: ''[[Silhouette (novel)|Silhouette]]'') the Doctor proved to have a talent for holding a crowds' attention, having a strong sense of showmanship, ([[TV]]: ''[[The Magician's Apprentice]]'') and quick comedic timing. ([[TV]]: ''[[The Woman Who Lived]]'')
 
[[File:Doctor playing electric guitar in the TARDIS.jpg|thumb|The Doctor plays his electric guitar on the TARDIS. ([[TV]]: ''[[Before the Flood]]'')]]
The Twelfth Doctor was an excellent player of the [[electric guitar]] and could play with extreme confidence. Not only was he was able to play "[[Pretty Woman]]", ([[TV]]: ''[[The Magician's Apprentice]]'') the [[Sex Pistols]]' "[[God Save the Queen]]", ([[COMIC]]: ''[[Clara Oswald and the School of Death (comic story)|Clara Oswald and the School of Death]]'') [[Ludwig van Beethoven|Beethoven]]'s "[[Beethoven's Fifth Symphony|fifth symphony]]", ([[TV]]: ''[[Before the Flood]]'') "[[Wish You Were Here]]", ([[TV]]: ''[[The Woman Who Lived]]'') and "[[Amazing Grace]]", ([[TV]]: ''[[The Zygon Invasion]]'') he was also able to improvise his own tunes, ([[TV]]: ''[[The Magician's Apprentice]]'') such as one entitled "[[Clara (song)|Clara]]". ([[TV]]: ''[[Hell Bent]]'') He enjoyed playing guitar alongside one of his companions, Hattie, who was a professional bassist. ([[COMIC]]: ''[[The Twist (comic story)|The Twist]]'', ''[[Playing House (comic story)|Playing House]]'')
 
Similar to his [[Ninth Doctor|ninth incarnation]], the Twelfth Doctor could slow down his perception of time; in this case by locking himself in a secure location in his mind, embodied as his [[TARDIS control room]] with his companion present, where he could take the time to reevaluate the predicament he was in to his companion and find a way out of it. ([[TV]]: ''[[Heaven Sent]]'')

[[File:Twelfth_Doctor_in_Black_Archive_The_Zygon_Inversion.jpg|thumb|left|The Doctor defends peace in the [[Black Archive]]. ([[TV]]: ''[[The Zygon Inversion]]'')]]
Compared to his prime self, this version of the Twelfth Doctor was much more ragged, bring much older and sporting a white beard with overgrown white hair to match. He had also changed his attire as well, no longer sporting an overcoat.
In his twelfth incarnation, the Doctor was a tall, thin-faced man with a tousled mop of silver-grey hair and intense eyes framed by unruly, expressive eyebrows. ([[PROSE]]: ''[[The Crawling Terror]]'') He had a hooked nose, with big ears, ([[TV]]: ''[[The Time of the Doctor]]'') and sharp silvery blue eyes. ([[TV]]: ''[[The Day of the Doctor]]'') He was of a light build. ([[COMIC]]: ''[[Chime Time (comic story)|Chime Time]]'')
 
Most changed were his eyebrows, which went from "delicate" ([[TV]]: ''[[The Time of the Doctor]]'') to extremely thick and furrowed. ([[TV]]: ''[[The Day of the Doctor]]'') Startled by the change, the Doctor described them as "attack eyebrows", which could "take bottle tops off" and were "ready to set up their own independent state of eyebrows". ([[TV]]: ''[[Deep Breath]]'') He later considered his intimidating eyebrows as both a major contributor to his gravitas, ([[TV]]: ''[[Time Heist]]'') and the reason many viewed him as a hostile. ([[COMIC]]: ''[[The Swords of Kali (comic story)|The Swords of Kali]]'')
 
Tall and gaunt, he was called a "boney rascal" and a "desiccated man-crone" by [[Robin Hood]], who also described the Doctor as being "pale as [[milk]]". ([[TV]]: ''[[Robot of Sherwood]]'') Clara once described him as looking like a "grey-haired stick insect", ([[TV]]: ''[[Listen]]'') with [[Shona McCullough]] described him as a "skeleton man". ([[TV]]: ''[[Last Christmas (TV story)|Last Christmas]]'')
 
[[Governor (The Blood Cell)|The Governor]] believed the Doctor had "a face for fury", and that it was "made up of storms" and "[boiled] away like a dying star". ([[PROSE]]: ''[[The Blood Cell]]'') Clara also noted that the Doctor's face "always looked serious." ([[PROSE]]: ''[[Silhouette (novel)|Silhouette]]'') [[Ross McNamara]] compared the Doctor's "craggy" face to "the surface of the moon." ([[PROSE]]: ''[[Haunted (short story)|Haunted]]'')
 
Upon first seeing his reflection at [[Madame Vastra]]'s house, the Doctor described it as "absolutely furious." Though he later admitted that his new face was "all right up until the eyebrows," he still did not like it. ([[TV]]: ''[[Deep Breath]]'') The Doctor later described himself as a "distinguished gentleman with [a] twinkle in his eye." ([[COMIC]]: ''[[The Swords of Kali (comic story)|The Swords of Kali]]'')
 
Physically, he resembled an older version of [[Lobus Caecilius]], ([[TV]]: ''[[The Fires of Pompeii]]'') with the Doctor himself noting he that had "seen [his] face somewhere before". ([[TV]]: ''[[Deep Breath (TV story)|Deep Breath]]'') When he realized that he had seen his face when his [[Tenth Doctor|tenth incarnation]] saved Caecilius's family from the destruction of Pompeii on [[Donna Noble]]'s insistence, the Doctor concluded he subconsciously chose Caecilius' face to "hold [himself] to the mark" and remind him that he "save[d] people." ([[TV]]: ''[[The Girl Who Died]]'')
 
At some point, the Doctor appeared to have had his left earlobe pierced, and had visible scarring there by the time he extracted Clara from her timeline. ([[TV]]: ''[[Hell Bent (TV story)|Hell Bent]]'')
 
=== Hair and grooming ===
The Twelfth Doctor's hair was a silvery shade of grey, ([[TV]]: ''[[The Time of the Doctor (TV story)|The Time of the Doctor]]'') which confused Clara, as she thought regeneration made the Doctor younger. ([[TV]]: ''[[Deep Breath (TV story)|Deep Breath]]'')
 
His hair was originally short and combed down, ([[TV]]: ''[[The Time of the Doctor]]'', ''[[Deep Breath]]'') though occasionally styled into a quaff. ([[TV]]: ''[[The Caretaker]]'') However, he later let his hair grow out, and become curlier. ([[TV]]: ''[[Last Christmas (TV story)|Last Christmas]]'', ''[[The Doctor's Meditation]]'', ''[[Hell Bent (TV story)|Hell Bent]], [[For Tonight We Might Die (TV story)|For Tonight We Might Die]],'' [[The Return of Doctor Mysterio (TV story)|''The Return of Doctor Mysterio'']])
 
For reasons as yet unexplained, the Doctor's hair appeared to change length - long to short to long again - during an incident in which he was trapped within the TARDIS. ([[TV]]: ''[[Flatline (TV story)|Flatline]]'')
 
=== Clothing ===
==== Main attires ====
Immediately following his regeneration, the Doctor initially wore his predecessor's attire, a Victorian nightshirt, and then a coat that he "bought" from a tramp, before stealing a Clockwork Droid's suit in order to masquerade as one. ([[TV]]: ''[[Deep Breath]]'') After having a chance to return to the TARDIS, though, the Doctor chose a new outfit for himself, with the intention of "aiming for minimalism", but instead felt that he "came out with magician" after solidifying his wardrobe, ([[TV]]: ''[[Time Heist]]'') though Clara noted his clothes made him look Victorian. ([[PROSE]]: ''[[Silhouette (novel)|Silhouette]]'')
 
[[File:The Doctor's New Look.jpg|thumb|right|The Doctor shows off his new look to Clara, inside his refurbished TARDIS. ([[TV]]: ''[[Deep Breath]]'')]]
The Doctor initially donned a navy blue Crombie coat and cardigan with a white collared shirt, matching dark blue trousers, and black brogue boots. Over the top, he sported a thigh-length, dark blue jacket with red lining, often wearing it with the top button done. On his left hand ring finger, he had a pair of gold rings, a normal gold band and a second ring with a greenish amber setting that rested atop the first band. ([[TV]]: ''[[Deep Breath]]'') Occasionally, the Doctor would replace his cardigan with a waistcoat, with colours ranging in dark blue and plain black, ([[TV]]: ''[[Mummy on the Orient Express]]'', ''[[Face the Raven]]'') and change his dark blue trousers to black. ([[TV]]: ''[[Under the Lake]]'', ''[[Face the Raven]]'') His socks were either decorated with cartoon animals ([[PROSE]]: ''[[The Blood Cell]]'') or plain black, ([[TV]]: ''[[Heaven Sent]]'') and his underpants had question marks. ([[TV]]: ''[[The Zygon Invasion]]'')
 
Though his Crombie coat remained a constant staple of his appearance, with colours coming in navy blue, ([[TV]]: ''[[Deep Breath]]'') black, ([[COMIC]]: ''[[The Eye of Torment (comic story)|The Eye of Torment]]'') lapis blue, ([[COMIC]]: ''[[The Hyperion Empire (comic story)|The Hyperion Empire]]'') and maroon velvet, ([[COMIC]]: ''[[The Highgate Horror (comic story)|The Highgate Horror]]'') the Doctor would wear variations of his attire, switching from vested garments with a white collared shirt for a simple dress shirt on its own, coloured in maroon, ([[TV]]: ''[[Robot of Sherwood]]'') dark blue, ([[TV]]: ''[[Time Heist]]'') or black with a white polka dot pattern. ([[TV]]: ''[[Kill the Moon]]'')
 
Other times, he would dispense with the shirt as well and don a black crew neck jumper ([[TV]]: ''[[Listen]]'') with small star-shaped sparkles on the front that helped him see in the dark, ([[PROSE]]: ''[[Royal Blood (novel)|Royal Blood]]'') and later began wearing a hooded top over his jumper, with colours ranging in plain black, ([[TV]]: ''[[Last Christmas (TV story)|Last Christmas]]'') and bluish gray. ([[TV]]: ''[[The Woman Who Lived]]'') Under his jumper, he wore a white, ([[TV]]: ''[[Listen]]'') red ([[TV]]: ''[[The Woman Who Lived]]'') or grey T-shirt. ([[COMIC]]: ''[[Time and PR in Space (comic story)|Time and PR in Space]]'')
 
In his "rock star" image, the Doctor continued to wear his hoodie under his Crombie coat, but replaced his jumper with a T-shirt and a pair of baggy plaid trousers similar in style as his [[Second Doctor|second incarnation]], either in a light grey colour, a dark blue design with a white plaid pattern, a dark blue tartan pattern, ([[TV]]: ''[[The Doctor's Meditation]]'', ''[[The Girl Who Died]]'', ''[[The Woman Who Lived]]'') or a bottle green colour. ([[COMIC]]: ''[[The Ministry of Time (comic story)|The Ministry of Time]]'') His vest wear included a dusty pink Henley top underneath a Misty Mountain T-shirt, ([[TV]]: ''[[The Doctor's Meditation]]'') a Negative Flower T-shirt, ([[TV]]: ''[[The Girl Who Died]]'') a plain white T-shirt, ([[COMIC]]: ''[[The Ministry of Time (comic story)|The Ministry of Time]]'') and a black T-shirt with a shark on it. ([[TV]]: ''[[Face the Raven]]'')
 
During his time at [[St Luke's University]], the Doctor began wearing a black velvet frockcoat with a cornflower blue lining, while the rest of the his outfit came with many variations. Accompanying the frockcoat would be a puce or dark green hoodie, a black distressed jumper, a white shirt or longline burgundy or blue t-shirt, and a blue or black waistcoat with notched lapels and brown buttons. ([[TV]]: ''[[The Pilot]]'')
 
==== Other costumes ====
While imprisoned on [[the Prison]], the Doctor was fitted with a standard orange uniform. ([[PROSE]]: ''[[The Blood Cell]]'')
 
When going into "deep cover" as [[Coal Hill School]]'s temporary caretaker, the Doctor donned an ocher brown warehouse coat over his black crew neck jumper. ([[TV]]: ''[[The Caretaker]]'')
 
[[File:Orient dress.jpg|left|thumb|The Doctor and Clara dress formally for a journey aboard the [[Orient Express (spacecraft)|Orient Express]]. ([[TV]]: ''[[Mummy on the Orient Express (TV story)|Mummy on the Orient Express]]'')]]
For formal wear, the Doctor would don a black double-breasted evening jacket, black trousers and waistcoat, his black brogue boots, a white dress shirt and a black cravat. ([[TV]]: ''[[Mummy on the Orient Express (TV story)|Mummy on the Orient Express]]'', ''[[The Husbands of River Song (TV story)|The Husbands of River Song]]'')
 
While visiting [[1963]] [[Las Vegas]], the Doctor donned a blue [[Fedora]] at Clara's urging. ([[COMIC]]: ''[[Gangland (comic story)|Gangland]]'')
 
To go with his red Crombie coat, the Doctor also owned velvet red trousers, shoes and waistcoat. ([[COMIC]]: ''[[The Highgate Horror (comic story)|The Highgate Horror]]'')
 
When [[Zip Betterblast]] gave him a "re-design" for his TV appearance, the Doctor received blue jeans, a cap with a "DW" logo, and yellow sleeveless V-neck top with a palm tree island image on it. ([[COMIC]]: ''[[Time and PR in Space (comic story)|Time and PR in Space]]'')
 
After returning to [[Gallifrey]], the Doctor discarded his waistcoat and velvet Crombie coat in favour of a black overcoat, which he found in his [[Barn (The Day of the Doctor)|old barn]]. He later resumed wearing his Crombie coat when he returned to his TARDIS; it is not the same outfit he wore on Gallifrey, however, but a replacement gifted to him by Clara Oswald at the same time she wrote her farewell message on his blackboard. ([[TV]]: ''[[Hell Bent (TV story)|Hell Bent]]'')
 
== Behind the scenes ==
* Like the [[War Doctor|War]] and [[Ninth Doctor]]s, the Twelfth Doctor debuted on television before his [[regeneration]] from his predecessor was screened. The Eighth Doctor similarly appeared before also with narration at the start of [[TV]]: ''[[Doctor Who]]''. 
* Capaldi is the second actor, after [[Sixth Doctor]] actor [[Colin Baker]], to have played an on-screen character in ''Doctor Who'' before being cast as the Doctor. If one counts [[David Tennant]]'s appearances in various Big Finish audios and ''[[Scream of the Shalka (webcast)|Scream of the Shalka]]'' prior to his casting as the [[Tenth Doctor]], Capaldi is the third actor to have appeared in-continuity prior to taking on the role.
* His first words — "Kidneys! I've got new kidneys!" — keep to the modern tradition of new Doctors commenting on their bodies soon after the change. Previously, the [[Ninth Doctor]] commented on his ears, ([[TV]]: ''[[Rose (TV story)|Rose]]'') the [[Tenth Doctor]] commented on his "new [[teeth]]", ([[TV]]: ''[[The Parting of the Ways (TV story)|The Parting of the Ways]]'') and the [[Eleventh Doctor|Eleventh]] on his legs. ([[TV]]: ''[[The End of Time (TV story)|The End of Time]]'')
** In [[DWM 477]], showrunner [[Steven Moffat]] jokingly answered one fan's question on what colour the Doctor's kidneys now were (he had complained he hated their colour) as "Froon. This is an entirely new colour, which only the Doctor can see."
* His costume was revealed in [[DWM 470]] and online earlier than planned to preempt a tabloid scoop.
* Aside from its official narrative comic strip, the Twelfth Doctor is also featured in ''[[The Daft Dimension]]'', a humour comic strip also published in ''[[Doctor Who Magazine]]''.
* Peter Capaldi wanted to wear his wedding ring as part of his Doctor's attire, and requested a prop to disguise it. He was given an amber ring with a gemstone that fits over the top of his original band. The [[First Doctor]] also wore a gemstone ring, and as such the Twelfth Doctor is the first incarnation since then seen to sport one. He is also the first incarnation since the [[Third Doctor]] to wear an ordinary ring. Although ''The Husbands of River Song'' reveals that the Doctor was still technically married to River Song during the events of Series 8 and 9, the Doctor's ring has yet to be directly identified as an actual wedding ring (and the Eleventh Doctor never sported such a ring during the time he was married to River).
** Promotional material for ''[[Doctor Who Experience (London/Cardiff)|Doctor Who Experience]]'' mentions that the green amber stone on the Twelfth Doctor's ring was 'allegedly' collected on the [[planet]] [[Raxacoricofallapatorius]]. However, this has yet to be stated in the narrative.
* Although this has yet to be explicitly confirmed on screen, it would appear that the Twelfth Doctor retains the artistic skill shown by the Eleventh Doctor. Writing in [[DWM 495]], Steven Moffat confirmed that the photo-realistic painting of Clara seen during [[TV]]: ''[[Heaven Sent (TV story)|Heaven Sent]]'' was painted by the Doctor. Coincidentally, Capaldi himself is a trained artist, although his style is more on the caricature side.
* A narrative distinction with the Twelfth Doctor is his tendency to break the [[fourth wall]]. To date this has occurred in [[TV]]: ''[[Deep Breath (TV story)|Deep Breath]]'', ''[[Listen (TV story)|Listen]]'', ''[[Before the Flood (TV story)|Before the Flood]]'' and ''[[Heaven Sent (TV story)|Heaven Sent]]''. In the case of ''Before the Flood'', the episode's entire pre-credit sequence consists of a monologue delivered by the Doctor directly to the viewer, with the Doctor even at one point encouraging viewers to use [[Google]] to look up the [[bootstrap paradox]]. ''Listen'' begins with the Doctor looking into the camera and intoning the episode title, and the remainder of the pre-credit sequence is another monologue, but this one appears to be addressed to either the TARDIS or the unknown entity the Doctor investigates in that episode. The other two examples are moments where the Doctor briefly looks at the camera.
* The Twelfth Doctor was dubbed in Japanese by [[Naoya Uchida]], in French by [[Philippe Résimont]], in German by [[Bernd Vollbrecht]] and Turkish by [[Müfit Coşkun]] .
* Peter Capaldi pierced his left ear earlier in life and the scar from this is clearly visible during the numerous extreme close-ups of his face in ''Hell Bent''.
* In several series 9 episodes, most notably ''Heaven Sent'', the Doctor displays a slight limp. This reflects the fact Capaldi injured his knee early in filming of the season; he underwent surgery to repair the knee late in 2015. [[Matt Smith]] developed the same knee injury during his tenure. As Capaldi later explained, "We realised what it is: you run down these corridors and you reach the end and then you spin to make sure you get a nice close-up. You spin on that leg and you put tension on that knee."<ref>{{cite web|url=http://www.express.co.uk/showbiz/tv-radio/746046/Doctor-Who-Christmas-2016-The-Return-of-Doctor-Mysterio-Peter-Capaldi-Steven-Moffat|title=Doctor Who star Peter Capaldi reveals 'dangerous and troubling' moment during filming|author=Debnath, Neela|date of source=21 December 2016|website name=Express|accessdate=23 December 2016}}</ref>

An alternate version of the Twelfth Doctor came into existence due to a continuity bomb.

History

After he sent his companion Clara Oswald away due to her betrayal, the Doctor spent centuries searching the universe for Gallifrey, until he gave up in despair and found the city of the Voord. After years among them, they offered him leadership of the group mind. The Doctor accepted and, upon joining them, began to remember the continuity bomb and how he was responsible for the ordeal surrounding it.

Leaving the clues that got him there, the alternate Doctor waited on Marinus for his past self, along with his tenth incarnation and eleventh incarnations and their companions, and then fired upon them to direct them towards the continuity bomb.

The Doctor's plan begins. (COMIC: Four Doctors)

After they arrived in his timeline, the alternate Doctor took them to the Voord city, where he revealed himself as both the Voord leader and the mastermind behind the continuity bomb.

Immediately taking the TARDIS and handcuffing the six, the alternate Doctor explained how the Voord hid from the Siege of Trenzalore, and how he had maneuvered the events with the bomb into motion. He explained his plans to wipe their memories and lead to Voord to conquer the universe and become the new Time Lords. However, the three Doctors instigated a struggle that allowed Alice Obiefune and Gabby Gonzalez to escape. The alternate Doctor then took Clara and the three Doctors to a device called the Conscience, to have their memories altered.

As he gloated about his victory, Alice was killed by his Voord guards and Gabby began to frantically open the Doctor's comics in the hope they could help her. Much to her horror, inside the bundle was a miniature Weeping Angel, which grew to full size and sent her back in her own personal timeline to the café before the three Doctors arrived to greet their companions. Gabby warned the companions of what would occur if things went they way they had before, before fading from existence. (COMIC: Four Doctors)

A new timeline

Now prepared for his alternate self's deceptions, the original Twelfth Doctor led his past incarnations and their companions to Marinus to deliberately set of the continuity bomb and enter the Voord city through River Song's World. Once there, the Twelfth Doctor entered the Voord group mind, and was confronted by the alternate Doctor.

The alternate Doctor was able to overpower his younger self, until the Twelfth Doctor called in the Tenth and Eleventh Doctors to assist him. Learning that the Doctors had sabotaged the city's force field, the alternate Doctor surrendered and was erased from existence after Clara apologised for her future betrayal. (COMIC: Four Doctors)

Personality

to be added

Appearance

Compared to his prime self, this version of the Twelfth Doctor was much more ragged, bring much older and sporting a white beard with overgrown white hair to match. He had also changed his attire as well, no longer sporting an overcoat.
