'''Companion''' was a somewhat vague term used to describe [[the Doctor]]'s closest friends. ([[AUDIO]]: {{cs|Situation Vacant (audio story)}}, {{cs|No Place Like Home (audio story)}}, {{cs|Death and the Queen (audio story)}}) Such people knew the Doctor's "secret": that they were someone non-[[human]] who travelled in [[time]] and [[space]] in a [[police box]]-shaped craft called [[The Doctor's TARDIS|the TARDIS]]. The Doctor's companions often directly saved the Doctor's lives ([[TV]]: {{cs|Rose (TV story)}}, {{cs|The Family of Blood (TV story)}}) or provided the Doctor with a perspective that prevented them from abusing their [[Time Lord]] powers. ([[AUDIO]]: {{cs|To the Death (audio story)}}, [[TV]]: {{cs|School Reunion (TV story)}}, {{cs|The Runaway Bride (TV story)}}, {{cs|The Fires of Pompeii (TV story)}}) On some occasions, they were the proximate reason that the Doctor sacrificed their then-current life and [[regenerated]]. ([[TV]]: {{cs|The Caves of Androzani (TV story)}}, {{cs|The Parting of the Ways (TV story)}}, {{cs|The End of Time (TV story)}}) On others, they lost their lives in pursuit of the Doctor's goals. ([[TV]]: {{cs|The Daleks' Master Plan (TV story)|namedep=The Traitors (4)}}, {{cs|The Daleks' Master Plan (TV story)|namedep=Destruction of Time (12)}}, {{cs|Earthshock (TV story)}}, {{cs|Voyage of the Damned (TV story)}}, {{cs|Face the Raven (TV story)}}, [[AUDIO]]: {{cs|Absolution (BFM audio story)}}, {{cs|To the Death (audio story)}})


Because the term was a shortening of the expression "travelling companion", most companions did in fact voyage with him in the TARDIS. Depending on the situation, other words were used to describe the same relationship — most frequently, "'''assistant'''".  However, it was somewhat unusual to hear the Doctor describe his friends using ''either'' term, and different incarnations seemed to have different preferences. The [[Third Doctor]], perhaps owing to his unique situation of [[exile on Earth|exile]], most frequently used the term "assistant". ([[DW]]: ''[[The Ambassadors of Death]]'', ''[[Terror of the Autons]]'') On the other hand, the [[Eighth Doctor]] — whilst running a competition to find a new companion — was forced to define the word ''companion'' and eschewed the term ''assistant'' in favour of ''friend''. ([[BFA]]: ''[[Situation Vacant]]'')
The [[Eleventh Doctor]] told [[Amy Pond]] he travelled with companions to see the [[universe]] through the [[eye]]s of somebody who hadn't experienced it all already. ([[HOMEVID]]: {{cs|Meanwhile in the TARDIS (home video)}}) He also mentioned that he took great care in choosing them. ([[TV]]: {{cs|Amy's Choice (TV story)}}) Once they left the Doctor's company, most companions used their newfound perspective of life and morality to help others; [[Sarah Jane Smith]] once noted that with them around "the Doctor" - their ideology and legacy - would never die. ([[TV]]: {{cs|Death of the Doctor (TV story)}}) [[Rose Tyler]] felt she had learned a "better way of living life" from her time spent with the [[Ninth Doctor]], and earned a new resolve to take action, to make a stand when things needed changing. ([[TV]]: {{cs|The Parting of the Ways (TV story)}}) The companions also helped the Doctor in their battles against evil throughout time and space. ([[TV]]: {{cs|The Ultimate Foe (TV story)}}) In particular, Ace called the [[Dalek]]s "the catch" to being a companion, ([[AUDIO]]: {{cs|Enemy of the Daleks (audio story)}}) while [[Clara Oswald]] described them as a companion's deadliest foe. ([[PROSE]]: {{cs|The Companion's Companion (novel)}})


Both terms were sometimes troublesome for others. For instance, the [[London]] [[police]] once interpreted the word "companion" sexually. ([[DW]]: ''[[Aliens of London]]'') On another occasion, two of the Doctor's companions briefly bickered over the appropriateness of the term "assistant"; [[Rose Tyler]], once flatly said, "I'm not his assistant" when [[Sarah Jane]] called her one, which caused Sarah to ironically exclaim "Get you, tiger!", intimating that Rose was just fooling herself. ([[DW]]: ''[[School Reunion]]'')  However, Rose seemed happier being called a "companion", as when [[Harriet Jones]] called out over the [[Sub-Wave Network]] for "former companions of the Doctor". ([[DW]]: ''[[The Stolen Earth]]'')  
Because the term was a shortening of the expression "travelling companion", most companions did in fact voyage with the Doctor in the TARDIS. Depending on the situation, other words were used to describe the same relationship — most frequently, "assistant". However, it was unusual to hear the Doctor call their friends by ''either'' word. Different incarnations had different preferences. The [[Third Doctor]], perhaps owing to his unique situation of [[exile on Earth|exile]], most frequently used the term "assistant". ([[TV]]: {{cs|The Ambassadors of Death (TV story)}}, {{cs|Terror of the Autons (TV story)}}) On the other hand, when the [[Eighth Doctor]] was forced to define the word ''companion'', he eschewed the term ''[[assistant]]'' in favour of ''[[friend]]''. ([[AUDIO]]: {{cs|Situation Vacant (audio story)}}) [[Sarah Jane Smith|Sarah Jane]] once implied the Doctor's companions served as a surrogate [[family]] for them, despite the Time Lord's insistence that they were alone in the universe. ([[TV]]: {{cs|Journey's End (TV story)}}) [[Martha Jones]] even stated the Doctor took on companions to ease their loneliness. ([[TV]]: {{cs|The Family of Blood (TV story)}})
People were companions or assistants to the Doctor for varying lengths of time, but most stayed with the Doctor for more than one adventure. ([[DW]]: ''[[An Unearthly Child]]'', ''[[The Daleks]]'', ''[[The Rescue]]'', ''[[The Romans]]'', ''[[The Chase]]'', ''[[The Time Meddler]]'', et al.) Some were known to stay for a few days, while others stayed for years. ([[BFA]]: ''[[No Place Like Home]]'')


Other [[Time Lord]]s, usually [[Renegade Time Lord|renegades]], sometimes had travelling companions.These companions were not nearly so well-documented as the Doctor's companions.
Both terms were occasionally troublesome. Sometimes, the word ''companion'' was interpreted [[sexual relationship|sexually]], leading to confusion about the Doctor's relationship with their friends. ([[TV]]: {{cs|Aliens of London (TV story)}}, {{cs|Closing Time (TV story)}}) Sometimes, companions bickered over the appropriateness of the word ''assistant''. [[Rose Tyler]] said emphatically, "I'm not his assistant" when [[Sarah Jane Smith]] called her one. ([[TV]]: {{cs|School Reunion (TV story)}}) Rose seemed happier being called a "companion", as when [[Harriet Jones]] called out over the [[Sub-Wave Network]] for "former companions of the Doctor". ([[TV]]: {{cs|The Stolen Earth (TV story)}}) [[Donna Noble]] was not too keen on being referred to as a ''companion'', thinking it sounded as if "[they] [[parking|park]] [the Doctor] on the seafront at [[Weston-super-Mare]]". ([[TV]]: {{cs|The Giggle (TV story)}})
 
Another term was ''associate'', which was used primarily by the [[Dalek]]s. ([[TV]]: {{cs|The Parting of the Ways (TV story)}}, {{cs|The Big Bang (TV story)}}, {{cs|The Witch's Familiar (TV story)}}) The [[Eleventh Doctor]] himself once introduced [[Clara Oswald]] to [[Mother Superious]] [[Tasha Lem]] as his associate. ([[TV]]: {{cs|The Time of the Doctor (TV story)}})
 
People were companions or assistants to the Doctor for varying lengths of time, but most stayed with him for more than one adventure. ([[TV]]: {{cs|An Unearthly Child (TV story)}}, {{cs|The Daleks (TV story)}}, {{cs|The Rescue (TV story)}}, {{cs|The Romans (TV story)}}, {{cs|The Chase (TV story)}}, {{cs|The Time Meddler (TV story)}}, et al.) Some stayed for a few days, while others were with them for years. ([[AUDIO]]: {{cs|No Place Like Home (audio story)}}, {{cs|Absent Friends (audio story)}}) On occasion, companions could be separated from the Doctor for months or years before they resumed travelling with them. ([[TV]]: {{cs|The Doctor, the Widow and the Wardrobe (TV story)}}, [[AUDIO]]: {{cs|The Juggernauts (audio story)}}) Other [[Time Lord]]s, usually [[Renegade Time Lord|renegades]], sometimes had travelling companions.

==== Humans ====
In the main, the Doctor travelled with [[human]]s, a number of whom were from the [[20th century|20th]] and [[21st century|21st centuries]]. ([[DW]]: ''[[An Unearthly Child]]'', ''[[The Massacre of St Bartholomew's Eve]]'', ''[[The War Machines]]'', ''[[The Wheel in Space]]'', ''[[Rose (TV story)|Rose]]'', ''[[Dalek (TV story)|Dalek]]'', ''[[School Reunion]]'', et al.) His fondness for humans was one of the reasons he was [[exile on Earth|exiled to Earth]] by the [[Time Lord]]s. ([[DW]]: ''[[The War Games]]'') Amongst his human companions, he tended to prefer young women — a fact he once sheepishly tried to hide from [[Amy Pond]]. ([[DW]]: ''[[Meanwhile in the TARDIS]]'')
[[File:Eighth Doctor companions.jpg|thumb|right|Four of the Doctor's companions - all female humans from varying times. ([[AUDIO]]: ''[[Ravenous 3]]'')]]
In the main, the Doctor travelled with [[human]]s, mostly from the [[20th century|20th]] and [[21st century|21st centuries]]. ([[TV]]: {{cs|An Unearthly Child (TV story)|namedep=An Unearthly Child (1)}}, {{cs|The Massacre (TV story)|namedep=Bell of Doom (4)}}, {{cs|The War Machines (TV story)}}, {{cs|The Wheel in Space (TV story)}}, {{cs|Rose (TV story)}}, {{cs|Dalek (TV story)}}, {{cs|School Reunion (TV story)}}, et al.) Their fondness for humans was one of the reasons they were [[exile on Earth|exiled to Earth]] by the [[Time Lord]]s. ([[TV]]: {{cs|The War Games (TV story)}}) Despite the Doctor claiming to be all alone, [[Sarah Jane Smith]] told the Tenth Doctor that he had the biggest family in the universe: them. ([[TV]]: {{cs|Journey's End (TV story)}})
 
Most of the Doctor's human companions were from either the mid-late 20th century ([[TV]]: {{cs|An Unearthly Child (TV story)|namedep=An Unearthly Child (1)}}, {{cs|The Massacre (TV story)|namedep=Bell of Doom (4)}}, {{cs|The War Machines (TV story)}}, {{cs|The Time Warrior (TV story)}}, et al.) or the early 21st century. ([[TV]]: {{cs|Rose (TV story)}}, {{cs|Smith and Jones (TV story)}}, {{cs|Partners in Crime (TV story)}}, et al.) The vast majority of companions from this time period were either [[English language|English]] or picked up by the Doctor in [[England]]. There were exceptions to this, however. The [[American]] [[Peri Brown]] met the Doctor whilst holidaying in [[Lanzarote]]. ([[TV]]: {{cs|Planet of Fire (TV story)}})
 
===== Gender =====
Amongst the Doctor's human companions, a high number of them were young women — a fact the [[Eleventh Doctor]] once tried sheepishly to hide from [[Amy Pond]]. ([[HOMEVID]]: {{cs|Meanwhile in the TARDIS (home video)}})
 
[[File:StevenHeadOnTheBomb.jpg|thumb|left|[[Steven Taylor]] was a rarity — a male human who, after [[Sara Kingdom]]'s death, travelled with the Doctor for a period of time when there were no female companions.]]
 
It was the [[First Doctor]] who first had multiple adventures ''exclusively'' with a man from Earth, [[Steven Taylor]]. ([[TV]]: {{cs|The Massacre (TV story)}}, [[PROSE]]: {{cs|Roses (short story)}}, {{cs|Making History (short story)}}, {{cs|Waiting for Jeremy (short story)}}) The Doctor's [[second Doctor|second incarnation]] was never long without [[Jamie McCrimmon]] at his side, ([[COMIC]]: {{cs|Action in Exile (comic story)}} - {{cs|The Night Walkers (comic story)}}, [[PROSE]]: {{cs|World Game (novel)}}, {{cs|Golem (short story)}}, {{cs|Blue Road Dance (short story)}}, {{cs|Scientific Adviser (short story)}}, {{cs|That Time I Nearly Destroyed the World Whilst Looking for a Dress (short story)}}, {{cs|Mother's Little Helper (short story)}}, {{cs|Reunion (ST short story)}}, {{cs|Dust (short story)}}) even after [[The Doctor's trial (The War Games)|his trial]] with the [[Time Lord]]s. ([[PROSE]]: {{cs|The Time Eater (short story)}}, [[COMIC]]: {{cs|Invasion of the Quarks (comic story)}} to {{cs|Martha the Mechanical Housemaid (comic story)}})
 
The [[Fifth Doctor]] also adventured with a [[World War II]] [[American]] pilot, [[Angus Goodman|Gus]], ([[COMIC]]: {{cs|4-Dimensional Vistas (comic story)}} - {{cs|The Moderator (comic story)}}) and the [[Eighth Doctor]] may have travelled solo with his long-term companion, [[Fitz Kreiner]]. ([[PROSE]]: {{cs|Escape Velocity (novel)}})
 
The Doctor's relationship with their companions usually remained platonic, though [[gender]] as well as [[sexuality]] could play a role in romantic or sexual feelings being harboured in either direction.
 
The [[Eighth Doctor]] described beginning to feeling sexual and romantic urges for the first time, but found it important to stress to [[I.M. Foreman]] that it wouldn’t be fair on any of his companions for them to get involved with him. ([[PROSE]]: {{cs|Interference - Book Two (novel)}})
 
Despite this acknowledged power dynamic, ([[PROSE]]: {{cs|Interference - Book Two (novel)}}) there were some encounters between the Eighth Doctor and his companions. In fact, [[Bernice Summerfield]] recalled having [[sex]] with him soon after his [[regeneration]]. ([[AUDIO]]: {{cs|Benny's Story (audio story)}}, [[PROSE]]: {{cs|The Dying Days (novel)}})


===== Male humans =====
The [[Ninth Doctor|Ninth]] and [[Tenth Doctor]]s shared a relationship with [[Rose Tyler]] which appeared romantic to outside observers, such as [[Mickey Smith]], ([[TV]]: {{cs|Boom Town (TV story)}}, {{cs|School Reunion (TV story)}}, {{cs|Rise of the Cybermen (TV story)}}, {{cs|Doomsday (TV story)}}) [[Martha Jones]] ([[TV]]: {{cs|The Sound of Drums (TV story)}}) and [[Donna Noble]]. ([[TV]]: {{cs|Journey's End (TV story)}})
Because female humans were, statistically, the most common sort of companion, male human companions were exceptional, and worthy of more detailed study. 
[[File:Massacre title.jpg|thumb|left|[[Steven Taylor]] was a rarity — a male human firmly known to have travelled with the Doctor for a period of time when there were no female companions. ([[DW]]: ''[[The Massacre of St Bartholomew's Eve]]'')]]
The Doctor's [[second Doctor|second incarnation]] was never long without a male assistant, and then typically only after the [[Time Lord]]s forcibly removed [[Jamie McCrimmon]] from his side. ([[TVC]]: ''at least'' ''[[Action in Exile]]'' through ''[[The Night Walkers]]'', but possibly all TVC Second Doctor stories; [[PDA]]: ''[[World Game]]'', [[ST]]: '''[[Golem (short story)|Golem]]'', ''[[Blue Road Dance]]'', ''[[Scientific Adviser]]'', ''[[That Time I Nearly Destroyed the World Whilst Looking for a Dress]]'', ''[[Mother's Little Helper]]'', ''[[Reunion]]'', ''[[Dust]]'')


The Doctor's [[First Doctor|original incarnation]] ''almost'' always had a male companion following his introduction to [[Ian Chesterton]]. In fact, it was during his first life that the Doctor had multiple adventures ''exclusively'' with [[Steven Taylor|a male human]], ([[DW]]: "[[War of God]]", [[BE]]: ''[[Roses]]'', [[ST]]: ''[[Making History]]'', ''[[Waiting for Jeremy]]'') something that practically never happened thereafter.
Later on, the [[Eleventh Doctor]] married his on-and-off companion [[River Song]], in a ceremony both parties recognised as binding, ([[TV]]: {{cs|The Wedding of River Song (TV story)}}, {{cs|The Angels Take Manhattan (TV story)}}, {{cs|The Husbands of River Song (TV story)}}, [[HOMEVID]]: {{cs|Last Night (home video)}}, et al.) and which carried through to the Doctor’s other incarnations, even as they met out of order. ([[TV]]: {{cs|The Husbands of River Song (TV story)}}, [[AUDIO]]: {{cs|My Dinner with Andrew (audio story)}})


Still, it ''did'' happen, such as when the [[Fifth Doctor]] adventured with the [[World War II]] [[American]] soldier, [[Angus Goodman|Gus]]. ([[DWM]]: ''[[4-Dimensional Vistas]] - [[The Moderator]]'') It may have happened with the [[Eighth Doctor]]'s long-term companion, [[Fitz Kreiner]] ([[EDA]]: ''[[Escape Velocity]]'')
Romantic feelings were not always reciprocated. [[Martha Jones]] was in love with the Doctor but was rebuffed. ([[TV]]: {{cs|Last of the Time Lords (TV story)}}) Equally, [[Amy Pond]] was sexually interested in the Doctor but was firmly rejected. ([[TV]]: {{cs|Flesh and Stone (TV story)}}) When exposed to a [[Truth Field]] in the presence of the [[Eleventh Doctor]], [[Clara Oswald]] blurted out "I'm an English teacher from the planet Earth, and I've run off with a man from space because I really fancy..." She cut herself off and covered her mouth. ([[TV]]: {{cs|The Time of the Doctor (TV story)}}) The [[Twelfth Doctor]] admitted that he had thought of himself in some sense as Clara's [[boyfriend]] while in his [[eleventh incarnation]]. ([[TV]]: {{cs|Deep Breath (TV story)}})


Of course, according to some accounts, the Doctor ''also'' travelled solo with [[Jamie McCrimmon]] some time after [[The War Games#Episode ten|the Doctor's initial Time Lord trial]]. However, during some of these adventures, the female companion was described as being temporarily left behind somewhere. ([[DW]]: ''[[The Two Doctors]]'', [[CC]]: ''[[Helicon Prime (audio story)|Helicon Prime]]'') There were other accounts of the Doctor and Jamie travelling alone together, however, where no female companions were indicated. ([[ST]]: ''[[The Time Eater]]'', [[TVC]]: ''[[Invasion of the Quarks]]'' to ''[[Martha the Mechanical Housemaid]]'') Nevertheless, it was extremely unclear how these stories "fit" into the same timestream as other established events.
In [[Amy Pond]] and [[Rory Williams]], the [[Eleventh Doctor]] had a [[marriage|married]] couple aboard the TARDIS. ([[TV]]: {{cs|A Christmas Carol (TV story)}}, et al.) Rory sometimes had doubts as to whether Amy preferred the Doctor over him, leading to some tension. ([[TV]]: {{cs|Day of the Moon (TV story)}}) When [[Jo Jones]] found out about Amy and Rory, she felt embarrassed for having left the [[Third Doctor]] in order to get married to her husband [[Cliff Jones]]. ([[TV]]: {{cs|Death of the Doctor (TV story)}})


All of Jamie's solo adventures differed from the situation with Steven, where there was simply a clear gap between [[Sara Kingdom]]'s death and [[Dodo Chaplet]]'s arrival. 
==== Non-humans ====
[[File:ThirdFinneyPOTD.jpg|thumb|The [[Third Doctor]] and [[Finney]] steel themselves for the coming fight with the [[Dalek]]s. ([[TVA]]: ''[[The Planet of the Daleks]]'')]]
[[File:Frobisher Morphs.jpg|thumb|left|The Doctor's [[Whifferdill]] companion, [[Frobisher]], could morph into any form, but typically preferred to be a [[penguin]]. ([[COMIC]]: {{cs|Where Nobody Knows Your Name (comic story)}})]]
Later, the [[Third Doctor]] would have several one-off adventures with human males who travelled in the TARDIS with him, including [[Charlie Fisher]], [[Finney]], [[Tom Phipps|Tom]], [[Joe (Fogbound)|Joe]], [[Dave Lester]], and [[Harry Trant]]. ([[TVA]]: ''[[Backtime]]'', ''[[The Planet of the Daleks]]'', ''[[The Vortex]]'', ''[[Fogbound]]'', ''[[The Plant Master]]'', ''[[The Hungry Planet]]'') The last known human male companion to travel alone and for more than one adventure with the Doctor was a boy named [[Arnold (Children of the Evil Eye)|Arnold]]. ([[TVC]]: ''[[Children of the Evil Eye]], [[Nova]]'')
Despite a statistical preference for humans, the Doctor had non-human companions or at the very least, companions who were not from Earth or descended from its people. This included the First Doctor's earliest companion, [[Badger (Lungbarrow)|Badger]], an [[Avatroid]] that helped raise him as a [[childe]] in the [[House of Lungbarrow]].


The [[Fifth Doctor]] had several adventures with the male [[Turlough]], after [[Tegan]] left, but before [[Peri]] arrived. However, Turlough wasn't human, but [[Trion (species)|Trion]]. ([[DW]]: ''[[Planet of Fire]]'') Likewise, the [[Sixth Doctor|Sixth]] and [[Seventh Doctor]]s each had solo adventures with the male [[Frobisher]], but he wasn't human, and most of his "solo" adventures with the Doctor actually took place when [[Peri]] was temporarily in [[New York City]]. ([[DWM]]: ''[[Kane's Story]]'')
The non-human companions the Doctor travelled with usually had the outward appearance of a human or Time Lord. On at least three occasions they travelled with members of their own species. The longest serving were his granddaughter [[Susan Foreman]], ([[TV]]: {{cs|An Unearthly Child (TV story)}}, et al.) [[Romana]], ([[TV]]: {{cs|The Ribos Operation (TV story)}}, et al.) and [[John Who|John]] and [[Gillian Who]]. ([[COMIC]]: {{cs|The Klepton Parasites (comic story)}}) Lady [[Serena]] was significant as well, for sacrificing her life in service to the Doctor's goals. ([[PROSE]]: {{cs|World Game (novel)}}) Other human-like individuals with whom they adventured included, but certainly weren't limited to: [[Trakenite]] [[Nyssa]], ([[TV]]: {{cs|Logopolis (TV story)}}) [[Alzarian]] [[Adric]], ([[TV]]: {{cs|Full Circle (TV story)}}) [[Trion (species)|Trion]] [[Vislor Turlough]] ([[TV]]: {{cs|Mawdryn Undead (TV story)}}) and [[Astrid Peth]] from [[Sto]]. ([[TV]]: {{cs|Voyage of the Damned (TV story)}})


The [[Eleventh Doctor]] briefly travelled with [[Rory Williams|Rory]] as the only companion; Rory's wife [[Amy Pond|Amy]] was revealed to be a [[Ganger]] during their travels and the real Amy was abducted and taken to [[Demon's Run]]. After the Doctor melted Ganger Amy into raw [[The Flesh|Flesh]], the Doctor and Rory concentrated their efforts on locating the real Amy and recruiting an army to fight the kidnappers. ([[DW]]: ''[[The Almost People]]'', ''[[A Good Man Goes to War]]'')
On occasion, they were accompanied by obviously non-human species, like [[Whifferdill]]s, ([[COMIC]]: {{cs|The Shape Shifter (comic story)}}) [[Ice Warrior]]s, ([[COMIC]]: {{cs|Descendance (comic story)}}) [[Oblivioner]]s, ([[COMIC]]: {{cs|Bad Blood (comic story)}}) [[Eutermesan]]s, ([[AUDIO]]: {{cs|The Creed of the Kromon (audio story)}}) [[Vessican]]s ([[COMIC]]: {{cs|Thinktwice (comic story)}}) and [[cyber-converted]] humans. ([[COMIC]]: {{cs|The Company of Thieves (comic story)}}) During her time working for the Division, the [[Fugitive Doctor]] had a [[Lupar]] companion named [[Karvanista]]. ([[TV]]: {{cs|Once, Upon Time (TV story)}}, {{cs|The Vanquishers (TV story)}}) The [[Fourteenth Doctor]] briefly formed a companionship with a [[pig]], whom he named [[Alfredo (Under Control)|Alfredo]]. ([[PROSE]]: {{cs|Under Control (short story)}})


==== Near- and non-humans ====
Artificial life-forms sometimes travelled with the Doctor, as well. Clearly, [[K9]] was the Doctor's most-beloved robotic companion, given the number of models the Doctor built ([[TV]]: {{cs|The Invasion of Time (TV story)}}, {{cs|School Reunion (TV story)}}, {{cs|A Girl's Best Friend (TV story)}}) and the pleasure the Tenth Doctor displayed when he re-encountered a version of the robot. ([[TV]]: {{cs|School Reunion (TV story)}}, {{cs|The Wedding of Sarah Jane Smith (TV story)}}) The Doctor seemed empathetic to artificial life-forms with errors in their programming. The [[Fifth Doctor]] once effectively [[euthanasia|euthanised]] [[Kamelion|an android companion]] in irremediable distress. ([[TV]]: {{cs|Planet of Fire (TV story)}})
[[File:Frobisher Morphs.jpg|thumb|left|The Doctor's [[Whifferdill]] companion, [[Frobisher]], could morph into any form, but typically preferred to be a [[penguin]]. ([[DWM]]: ''[[Where Nobody Knows Your Name]]'')]]
Despite a statistical preference for humans, the Doctor did have non-human companions, or at the very least companions who were not from Earth. On at least three occasions he travelled with members of his own species, the most long-serving of whom were [[Susan Foreman|his own granddaughter]] and [[Romana II]] ([[DW]]: ''[[An Unearthly Child]]'', ''[[The Ribos Operation]]'', et al.) —but Lady [[Serena]] was significant as well, for sacrificing her life in service to the Doctor's goals. ([[PDA]]: ''[[World Game]]'') Other [[near-human]] species with whom he adventured included, but certainly weren't limited to: [[Trakenite]]s, [[Alzarian]]s, [[Kroton (Cyberman)|Cyber-converted humans]], and [[Sto|people from Sto]]. ([[DW]]: ''[[Logopolis (TV story)|Logopolis]]'', ''[[Full Circle]]'', [[DWM]]: ''[[The Company of Thieves]]'', [[DW]]: ''[[Voyage of the Damned]]'')


The Doctor did not always travel with humans, however. On occasion, he took on board [[the TARDIS]] obviously non-human species, like [[Whifferdill]]s, [[Ssard|Ice Warriors]], [[Oblivioner]]s, [[Eutermesan]]s, and [[Vessican]]s. ([[DWM]]: ''[[The Shape Shifter]]''; [[RT]]: ''[[Descendance]]''; [[DWM]]: ''[[Bad Blood (comic story)|Bad Blood]]''; [[BFA]]: ''[[The Creed of the Kromon]]''; [[DWM]]: ''[[Thinktwice]]'')
Shortly before his time on [[Trenzalore]], the [[Eleventh Doctor]] obtained a [[Cyberman]] head he named "[[Handles]]". Handles aided him greatly with technological assistance, being his only real companion during his first three hundred years on Trenzalore as he'd sent [[Clara Oswald]] home and everyone he cared about that lived there eventually died. After three hundred years, Handles died of old age, reducing the Doctor to tears. ([[TV]]: {{cs|The Time of the Doctor (TV story)}})


Artificial life-forms sometimes travelled with the Doctor, as well. Clearly, [[K9]] was the Doctor's most-beloved robotic companion, given the number of new models the Doctor built ([[DW]]: ''[[The Invasion of Time]]'', ''[[School Reunion]]'', [[KAC]]: ''[[A Girl's Best Friend]]'') and the enthusiasm he displayed when he re-encountered a version of the robot. ([[SJA]]: ''[[The Wedding of Sarah Jane Smith]]'') The Doctor seemed empathetic to artificial life-forms with errors in their programming; he once effectively [[wiktionary:euthanasia|euthanised]] [[Kamelion|an android companion]] in irremediable distress. ([[DW]]: ''[[Planet of Fire]]'') One android companion, [[Antimony]], whom the [[Seventh Doctor|Doctor]] built himself so not to be alone until travelled with him till he was destroyed by the renegade [[Time Lord]], [[Tannis]]. ([[WC]]: ''[[Death Comes to Time]]'')
The [[Twelfth Doctor]] teamed up with a [[Dalek]] named [[Lumpy]] to collect the [[Orb of Fates]] and stop the Daleks, [[Cyberman|Cybermen]] and [[Sontaran]]s from controlling the ''[[Starbane]]''. However, it turned out that Lumpy had tricked the Doctor at the very beginning of the adventure. ([[GAME]]: {{cs|The Doctor and the Dalek (video game)}}) His later companion, Nardole, was humanoid, but explicitly not human - he was at least partially cybernetic, ([[TV]]: {{cs|The Pilot (TV story)}}) harboured a distaste for humans, ([[TV]]: {{cs|Smile (TV story)}}, {{cs|The Doctor Falls (TV story)}}) and was only "human enough" because the Doctor had gotten his lungs cheap. ([[TV]]: {{cs|The Pyramid at the End of the World (TV story)}})

[[File:ZoeDiscoveredWheel.jpg|thumb|[[Zoe Heriot|Zoe]] is discovered attempting to stow away in the [[console room]]. ([[TV]]: {{cs|The Wheel in Space (TV story)}})]]
The Doctor began relationships with his assistants in a great variety of ways. Some, like [[Adric]], [[Leela]] and [[Zoe Heriot|Zoe]], stowed away on [[the TARDIS]], fully aware it was a ship that could take them away from their home environment. ([[DW]]: ''[[State of Decay]]'', ''[[The Face of Evil]]'', ''[[The Wheel in Space]]'') Others, like [[Ian Chesterton]], [[Barbara Wright]] and [[Dodo Chaplet]], were taken away from their homes without their consent. ([[DW]]: "[[An Unearthly Child]]", "[[Bell of Doom]]"). He was also occasionally assigned assistants by those in nominal authority over him. During his [[exile on Earth]], the Doctor's assistants were mostly supplied by [[the Brigadier]]. ([[DW]]: ''[[Spearhead from Space]]'', ''[[Terror of the Autons]]'') In the case of [[UNIT]] soldiers, the Doctor worked with whomever the Brigadier happened to have on duty at the time of a crisis. This was how he first met [[Mike Yates]]. ([[MA]]: ''[[The Eye of the Giant]]'') The Doctor's ''other'' "bosses" — the [[Time Lord]]s and the [[White Guardian]] — also occasionally provided companions, invariably against the Doctor's wishes. ([[PDA]]: ''[[World Game]]'', [[BFA]]: ''[[Blood of the Daleks]]'', [[DW]]: ''[[The Ribos Operation]]'')
The Doctor began relationships with their companions in a great variety of ways. Some, like [[Adric]], ([[TV]]: {{cs|State of Decay (TV story)}}) [[Leela]], ([[TV]]: {{cs|The Face of Evil (TV story)}}) [[Tara Mishra|Tara]], ([[COMIC]]: {{cs|Official Secrets (comic story)}}) and [[Zoe Heriot|Zoe]], ([[TV]]: {{cs|The Wheel in Space (TV story)}}) stowed away on [[the TARDIS]], fully aware it was a ship that could take them away from their home. Others, like [[Ian Chesterton]], [[Barbara Wright]] ([[TV]]: {{cs|An Unearthly Child (TV story)|namedep=An Unearthly Child (1)}}) and [[Dodo Chaplet]], ([[TV]]: {{cs|The Massacre (TV story)|namedep=Bell of Doom (4)}}) were taken away without their consent. They were also occasionally assigned assistants by those in nominal authority over him. During his [[exile on Earth]], the Third Doctor's assistants were mostly supplied by [[the Brigadier]]. ([[TV]]: {{cs|Spearhead from Space (TV story)}}, {{cs|Terror of the Autons (TV story)}}) In the case of [[UNIT]] soldiers, the Doctor worked with whomever the Brigadier happened to have on duty at the time of a crisis. This was how he first met [[Mike Yates]]. ([[PROSE]]: {{cs|The Eye of the Giant (novel)}}) The Doctor's ''other'' "bosses" — the [[Time Lord]]s ([[PROSE]]: {{cs|World Game (novel)}}, [[AUDIO]]: {{cs|Blood of the Daleks (audio story)}}) and the [[White Guardian]] ([[TV]]: {{cs|The Ribos Operation (TV story)}}) — also occasionally provided companions, invariably against the Doctor's wishes. Even the [[Dalek]]s understood that he was commonly assisted by companions. For example, when the Daleks abducted the [[Eleventh Doctor]] for a mission regarding the [[Dalek Asylum]], they also abducted his most recent companions, [[Amy Pond]] and [[Rory Williams]], to assist him. ([[TV]]: {{cs|Asylum of the Daleks (TV story)}}) Much like the UNIT soldiers that worked with the Doctor as assistants under her father, [[Kate Stewart]] tended to help the Doctor on Earth when the situation brought them together. ([[TV]]: {{cs|The Power of Three (TV story)}}, {{cs|The Day of the Doctor (TV story)}}, {{cs|The Magician's Apprentice (TV story)}}, {{cs|The Zygon Invasion (TV story)}} / {{cs|The Zygon Inversion (TV story)}}, {{cs|The Vanquishers (TV story)}}) However, while helping to stop [[The Master's Dalek Plan]], Kate briefly travelled in and even piloted the TARDIS, although it was made clear that this was the first time that she had ever stepped foot inside. Kate's constant help of the Doctor and her brief travel in the TARDIS appeared to grant her the status of companion as she was later invited by [[Graham O'Brien]] to a support group meeting of the Doctor's former companions. ([[TV]]: {{cs|The Power of the Doctor (TV story)}})


All that said, the most common way of initiating TARDIS travel was simply to be invited by the Doctor. Though there was, from their perspective, a significant gap of time between first becoming aware of the Doctor and getting to travel with him, [[Donna Noble]], [[Amy Pond]] and [[Rory Williams]] were companions who began travelling at the Doctor's request. ([[DW]]: ''[[The Runaway Bride]]'', ''[[Partners in Crime]]'', ''[[The Eleventh Hour]]'', ''[[The Vampires of Venice]]'') Likewise, [[Martha Jones]], [[Rose Tyler]], [[Jack Harkness]], [[Ace]], [[Vislor Turlough]], [[Izzy Sinclair]], [[Charley Pollard]], [[Arnold (Children of the Evil Eye)|Arnold]], [[Jamie McCrimmon]], [[Victoria Waterfield]], [[Vicki]] and others all began their travels with the Doctor because he asked them. ([[DW]]: ''[[Smith and Jones]]'', ''[[Rose (TV story)|Rose]]'', ''[[The Doctor Dances]]'', ''[[Dragonfire]]'', ''[[Mawdryn Undead]]'', [[DWM]]: ''[[Endgame (DWM comic story)|Endgame]]'', [[BFA]]: ''[[Storm Warning]]'', [[TVC]]: ''[[Children of the Evil Eye]]'', [[DW]]: ''[[The Highlanders]]'', ''[[The Evil of the Daleks]]'', ''[[The Rescue]]'')
All that said, the most common way of initiating [[TARDIS]] travel was to be invited by the Doctor. Although with some cases there was, from their perspective, a significant gap of time between first meeting of the Doctor and getting to travel with him, [[Donna Noble]], ([[TV]]: {{cs|The Runaway Bride (TV story)}}, {{cs|Partners in Crime (TV story)}}) [[Amy Pond]] ([[TV]]: {{cs|The Eleventh Hour (TV story)}}) and [[Rory Williams]] ([[TV]]: {{cs|The Eleventh Hour (TV story)}}, {{cs|The Vampires of Venice (TV story)}}) were companions who began travelling at the Doctor's request a significant amount of time after they first met. In most cases there was little to no time gap between meeting the Doctor and getting to travel with them, [[Clara Oswald]], ([[TV]]: {{cs|The Bells of Saint John (TV story)}}) [[Martha Jones]], ([[TV]]: {{cs|Smith and Jones (TV story)}}) [[Rose Tyler]], ([[TV]]: {{cs|Rose (TV story)}}) [[Jack Harkness]], ([[TV]]: {{cs|The Doctor Dances (TV story)}}) [[Ace]], ([[TV]]: {{cs|Dragonfire (TV story)}}) [[Vislor Turlough]], ([[TV]]: {{cs|Mawdryn Undead (TV story)}}) [[Izzy Sinclair]], ([[COMIC]]: {{cs|Endgame (DWM comic story)}}) [[Charley Pollard]], ([[AUDIO]]: {{cs|Storm Warning (audio story)}}) [[Arnold (Children of the Evil Eye)|Arnold]], ([[COMIC]]: {{cs|Children of the Evil Eye (comic story)}}) [[Jamie McCrimmon]], ([[TV]]: {{cs|The Highlanders (TV story)}}) [[Victoria Waterfield]], ([[TV]]: {{cs|The Evil of the Daleks (TV story)}}) [[Vicki Pallister|Vicki]] ([[TV]]: {{cs|The Rescue (TV story)|namedep=Desperate Measures (2)}}) and others all began their travels with the Doctor because he asked them. [[Mickey Smith]] became a companion by asking the Doctor if he could travel with him, rather than the other way around. ([[TV]]: {{cs|School Reunion (TV story)}})


Rarely, the Doctor invited people to travel with him, like [[Astrid Peth]], only to have their death prevent their travels. ([[DW]]: ''[[The Parting of the Ways]]'', ''[[Voyage of the Damned]]'', ''[[The God Complex]]'')
Other companions "forced" their way into the TARDIS. Leela, despite the [[Fourth Doctor]]'s protests, ran into the TARDIS and, before he could shoo her out, fiddled with the controls, causing it to dematerialise. ([[TV]]: {{cs|The Face of Evil (TV story)}})
 
Rarely, the Doctor invited people to travel with them, like [[Lynda Moss]], ([[TV]]: {{cs|The Parting of the Ways (TV story)}}) [[Astrid Peth]] ([[TV]]: {{cs|Voyage of the Damned (TV story)}}) and [[Rita (The God Complex)|Rita]], ([[TV]]: {{cs|The God Complex (TV story)}}) only to have their death prevent their travels. The same thing happened with [[Clara Oswin Oswald]], although the Doctor found out that there was another version of her somewhere in time and space and set out to find her. ([[TV]]: {{cs|The Snowmen (TV story)}})


==== Leaving the Doctor ====
==== Leaving the Doctor ====
The reasons people left the Doctor's side were as varied as the reasons they first walked through [[the TARDIS]] doors. However, reasons for discontinuing a relationship with the Doctor were broadly of three types: either the companion wanted to leave, ([[DW]]: ''[[The Chase]]'', ''[[The Myth Makers]]'', ''[[The Savages]]'', ''[[The War Machines]]'', ''[[Last of the Time Lords]]'') the Doctor wanted the companion to leave, ([[DW]]: ''[[The Dalek Invasion of Earth]]'', ''[[The Long Game]]'', ''[[Utopia (TV story)|Utopia]]'', ''[[The God Complex]]'') or some external force compelled the companion and Doctor to be separated. ([[DW]]: ''[[The Daleks' Master Plan]]'', ''[[The War Games]]'', ''[[The Hand of Fear]]'', ''[[Earthshock]]'', ''[[Doomsday]]'')
People left the Doctor for reasons as varied as the reasons they first walked through the [[The Doctor's TARDIS|TARDIS]] doors. They were of three broad types: the companion wanted to leave; ([[TV]]: {{cs|The Chase (TV story)|namedep=The Planet of Decision (6)}}, {{cs|The Myth Makers (TV story)|namedep=Horse of Destruction (4)}}, {{cs|The Savages (TV story)}}, {{cs|The War Machines (TV story)}}, {{cs|Last of the Time Lords (TV story)}}) the Doctor wanted the companion to leave; ([[TV]]: {{cs|The Dalek Invasion of Earth (TV story)|namedep=Flashpoint (6)}}, {{cs|The Long Game (TV story)}}, {{cs|Utopia (TV story)}}, {{cs|The God Complex (TV story)}}) or some external force compelled the companion and Doctor to separate.

When asked by [[Brian Williams]], father to one of their companions, [[Rory Williams]], and father-in-law to [[Amy Pond]], another companion, what happened to the people who travelled with them, the [[Eleventh Doctor]] explained that some left him, some got left behind, and also admitted that "not many, but some" died. ([[TV]]: {{cs|The Power of Three (TV story)}}) The [[Sixth Doctor]] confided in [[Jack Harkness]], who was abandoned by the [[Ninth Doctor]], that he did it to "the best of [their] companions and [[K9|the robot dog]]." ([[AUDIO]]: {{cs|Piece of Mind (audio story)}})

The choice to leave was sometimes the companion's.
 
A common reason for the departure of female [[human]] companions was romance. Sometimes, as with [[Vicki Pallister|Vicki]], ([[TV]]: {{cs|The Myth Makers (TV story)|namedep=Horse of Destruction (4)}}) [[Jo Grant|Jo]] ([[TV]]: {{cs|The Green Death (TV story)}}) and [[Leela]], ([[TV]]: {{cs|The Invasion of Time (TV story)}}) they left to get married, while at least one companion, [[Martha Jones]], left partly because she realised her romantic feelings for the [[Tenth Doctor]] would never be reciprocated. ([[TV]]: {{cs|Last of the Time Lords (TV story)}}) On other occasions, the Doctor travelled with married couples in the TARDIS, most notably [[Amy Pond]] and [[Rory Williams]]. ([[TV]]: {{cs|The Big Bang (TV story)}}, et al.)
[[File:IanBarbaraRealPoliceBox.jpg|thumb|[[Ian Chesterton|Ian]] and [[Barbara Wright|Barbara]] back home in [[London]] after their travels with the [[First Doctor]]. ([[TV]]: {{cs|The Chase (TV story)|namedep=The Planet of Decision (6)}})]]
In the Doctor's youth, before they had established reasonable control over [[the TARDIS]], companions sometimes left, at least in part, because they happened to have access to their own time period and wanted to return home. This was especially true of the companions who had not actually ''chosen'' to travel with the Doctor, such as [[Ian Chesterton|Ian]] and [[Barbara Wright|Barbara]], ([[TV]]: {{cs|The Chase (TV story)|namedep=The Planet of Decision (6)}}) [[Dodo Chaplet|Dodo]], ([[TV]]: {{cs|The War Machines (TV story)}}) and [[Polly Wright|Polly]] and [[Ben Jackson|Ben]]. ([[TV]]: {{cs|The Faceless Ones (TV story)}}) However, this sometimes happened later in the Doctor's life. [[Ly-Chee]], for instance, thought the [[Seventh Doctor]] was only offering him a lift into town. Instead, they had several adventures together. When the TARDIS finally deposited him in the correct town, he headed for the nearest pub and ordered a stiff [[alcohol|drink]] without once looking back. ([[COMIC]]: {{cs|The Enlightenment of Ly-Chee the Wise (comic story)}})

(''[[DW]]'': ''[[Last of the Time Lords]]'') 
Some companions left to improve a particular society they had encountered with the Doctor. [[Nyssa]] left to help cure [[Lazar's disease]], ([[TV]]: {{cs|Terminus (TV story)}}) whilst [[Steven Taylor]] stayed on the [[Planet (The Savages)|planet of the Elders]] to be its leader. ([[TV]]: {{cs|The Savages (TV story)}}) Likewise, [[Romana II]] chose to remain in [[E-Space]] to help the [[Tharil]] species. ([[TV]]: {{cs|Warriors' Gate (TV story)}}) [[Tara Mishra]] left the [[Ninth Doctor]] after wishing to stay and help with the disaster aftermath on [[Nomicae]], ([[COMIC]]: {{cs|The Bidding War (comic story)}}) though both parties made it explicit that this was temporary, and [[Jack Harkness]] was sent to collect her after some time. ([[COMIC]]: {{cs|The Lost Dimension (comic story)}}) Later, [[Mickey Smith]] deliberately stayed in the parallel [[Pete's World]] to help its citizens defeat the [[Cybusman|Cybermen]] and to support his [[Rita-Anne Smith|grandmother]]'s living [[Rita-Anne Smith (Pete's World)|parallel counterpart]]. ([[TV]]: {{cs|The Age of Steel (TV story)}}) Mickey proved especially independent when it came to departing the Doctor's side; he later left the TARDIS again, this time to return to his "home" Earth, ultimately to defend it from alien threats. ([[TV]]: {{cs|Journey's End (TV story)}}, {{cs|The End of Time (TV story)}})

Others left for more personal improvement. [[Melanie Bush]] parted ways from the [[Seventh Doctor]] purely to have new adventures in space — but not time — with [[Sabalom Glitz]]. ([[TV]]: {{cs|Dragonfire (TV story)}}) [[Frobisher]] left the Doctor to enjoy the pleasure planet [[A-Lux]]. ([[COMIC]]: {{cs|A Cold Day in Hell! (comic story)}}) [[Liz Shaw]] left [[UNIT]] and the [[Third Doctor]] to return to her research, telling [[the Brigadier]] that all the Doctor needed in an assistant was "someone to pass him his test tubes and tell him how brilliant he was". ([[TV]]: {{cs|Terror of the Autons (TV story)}}) After another brief adventure on [[Messaline]] [[Martha Jones]] declined to travel with the Doctor again wishing to be a part of [[UNIT]].

([[DW]]: ''[[Terror of the Autons]]'')
Some companions left simply because they no longer enjoyed travelling with the Doctor. [[Victoria Waterfield]] left because she had grown tired of the continual danger in which she found herself and decided to choose a safer new life. ([[TV]]: {{cs|Fury from the Deep (TV story)}}) [[Tegan Jovanka]] similarly left because she had become sickened by the death and destruction she witnessed. ([[TV]]: {{cs|Resurrection of the Daleks (TV story)}}) Likewise, [[Dan Lewis]] made the choice to leave following a near-death experience. ([[TV]]: {{cs|The Power of the Doctor (TV story)}})


Because they were [[Earth]]-based assistants who either never wanted to travel with the Doctor on a long-term basis or never were invited to do so, a few companions made only a single journey or two, but otherwise provided significant assistance from Earth. [[The Brigadier]] and [[Wilfred Mott]] were classic examples of this sort of assistant, ([[DW]]: ''[[The Invasion]]'', ''[[The Five Doctors]]'', ''[[The Stolen Earth]]'', ''[[The End of Time (TV story)|The End of Time]]'') but [[Maxwell Edison]] and, for a time, [[Mickey Smith]] could be viewed in this light as well. ([[DWM]]: ''[[Stars Fell on Stockbridge]]'', [[DW]]: ''[[Aliens of London]]''/''[[World War Three]]'', ''[[The Girl in the Fireplace]]'')

[[Harry Sullivan]] also left the Doctor to return to his usual life after a single trip in the TARDIS, ([[TV]]: {{cs|Terror of the Zygons (TV story)}}) albeit one punctuated by several detours by other means.
 
One companion who briefly left by her choice was [[Clara Oswald]]. After a trip to [[the Moon]] in which she was forced to decide whether to kill an innocent creature or to save planet Earth, the [[Twelfth Doctor]] refused to help, Clara grew so angry she left the TARDIS, telling the Doctor never to come and find her again. ([[TV]]: {{cs|Kill the Moon (TV story)}}) However, with the help of [[Danny Pink]], she realised she wasn't ready to give up the Doctor yet and agreed to a final trip with him weeks later to the ''[[Orient Express (spacecraft)|Orient Express]]'' at which point she decided to permanently rejoin him despite the dangers and the coldness the Doctor once again displayed on the trip. ([[TV]]: {{cs|Mummy on the Orient Express (TV story)}}) Clara again left the TARDIS after Danny's death, under the mistaken belief that the Doctor had found his home planet of [[Gallifrey]], while the Doctor believed that Danny was alive and with Clara. ([[TV]]: {{cs|Death in Heaven (TV story)}}) Later, the Doctor returned to save her life, in an adventure in which both lies were exposed. Afterwards, the Doctor gave Clara one more invitation to join him again, and she accepted. ([[TV]]: {{cs|Last Christmas (TV story)}})

[[Susan Foreman|Susan]], [[Arnold (Children of the Evil Eye)|Arnold]], [[John and Gillian]] were more charitably dismissed, the Doctor clearly believing he was doing them good by ending their travels.

There were occasions on which the Doctor and his companions became separated more by circumstance than by the wishes of either party. Perhaps the most obvious case of this was when the [[Tenth Doctor]] and [[Rose Tyler]] were separated by the closure of the walls between [[dimension]]s. ([[DW]]: ''[[Doomsday]]'') There were other cases of this sort. [[Sarah Jane Smith]]'s departure came about because the [[Fourth Doctor]] was summoned to [[Gallifrey]] ([[DW]]: ''[[The Hand of Fear]]'') at a moment in [[Gallifreyan history]] when [[human]]s weren't allowed on the planet. ([[DW]]: ''[[School Reunion]]'') The Time Lords forced [[Zoe Heriot|Zoe]] and [[Jamie McCrimmon|Jamie]] to part from the [[Second Doctor]], with only the memories of their first adventure with him intact. ([[DW]]: ''[[The War Games]]'') The Time Lords later claimed they had developed this procedure into a "standard response" for companions with whom they dealt. The [[Sixth Doctor]], for instance, encountered a version of [[Peri Brown]] who had been given "the Jamie and Zoe treatment". She retained memories only of the adventure with the [[Fifth Doctor]], [[Turlough]] and [[the Master (Tremas)|the Master]] which began on [[Lanzarote]]. ([[CC]]: ''[[Peri and the Piscon Paradox]]'') Finally, whilst in his [[tenth Doctor|tenth body]], the Doctor had to stabilise the effects of a biologically untenable combination of his [[DNA]] with [[Donna Noble]]'s. To do so, he had to submerge all memories of her time with him, and shield her from those memories being triggered lest she die. Thus, although he did, in a sense, kick her out of the TARDIS for her own good, neither wanted to part company. ([[DW]]: ''[[Journey's End]]'')

([[TV]]: {{cs|Journey's End (TV story)}}) She did briefly remember snippets of her travels but was knocked unconscious by it and then forgot again. ([[TV]]: {{cs|The End of Time (TV story)}}) Similarly, Donna's consciousness was saved to [[The Library]] against her will, causing her to forget about the Doctor and spending years from her point of view married to [[Lee McAvoy]]. This was only temporary, however, and soon afterwards she resumed her travels. ([[TV]]: {{cs|Silence in the Library (TV story)}} / {{cs|Forest of the Dead (TV story)}})
 
[[Jack Harkness]]' days in [[the TARDIS]] came to an end in similarly unusual circumstances. Because he had died and been resurrected by [[Bad Wolf (entity)|Rose as the Bad Wolf entity]], he became, in the words of the [[Tenth Doctor]] "just wrong". No longer able to die, he was instead a kind of "[[fixed point in time]]" which [[the TARDIS]] herself rejected.

Some companions died, often in service to the Doctor's goals. [[Katarina]] and [[Sara Kingdom]] both died on the quest to prevent the [[Dalek]]s from obtaining [[taranium]]. ([[DW]]: ''[[The Traitors]]'', ''[[The Destruction of Time]]'') [[Adric]] sacrificed himself trying to stop a pre-historic [[Cyberman]] invasion of [[Earth]]. ([[DW]]: ''[[Earthshock]]'') [[Roz Forrester]] died in battle.

Without her sacrifice, the [[Tenth Doctor]] wouldn't have been able to regain control of the ''[[Titanic (spaceship)|Titanic]]'', nor prevent it from having a costly collision into [[Buckingham Palace]]. ([[DW]]: ''[[Voyage of the Damned]]'')
 
[[Cinder]], who was briefly a companion of the [[War Doctor]], sacrificed her life to save the Doctor when the [[Time Lord]] [[Karlax]] tried to [[Assassination|kill]] him under orders from [[Rassilon]]. It was for fear of this highly probable eventuality of a companion's death that the War Doctor was reluctant to let a companion join him during his years of fighting in the [[Last Great Time War]]. He gave Cinder a proper burial and promised to end the Time War to honour her sacrifice. ([[PROSE]]: {{cs|Engines of War (novel)}})


Three unusual cases were those of [[Peri Brown]], [[Ace]] and [[River Song]].
Three unusual cases were those of [[Peri Brown]], [[Ace]] and [[River Song]].


Peri was killed by King [[Yrcanos]] on [[Thoros Beta]], whilst her body was being subjected to [[Crozier]]'s troubling body-swapping experimentations. For a time, the [[Sixth Doctor]] believed Peri had died. At the conclusion of his second major trial by the [[Time Lord]]s, however, the [[Inquisitor]] revealed that Peri's death had likely been a trick of the [[Valeyard]]. IThe Inquisitor showed the Doctor that Peri, far from being killed by Yrcanos, had in fact married him. ([[DW]]: ''[[Mindwarp]]'') However, at a later date, the Time Lords revealed their meddling with Peri's timestreams had resulted in multiple versions of Peri running around the cosmos. One of these Peris had in fact been killed by Yrcanos, as the Doctor originally believed. ([[CC]]: ''[[Peri and the Piscon Paradox]]'')

[[File:AceDeadGroundZero.jpg|thumb|Ace dies in the [[Seventh Doctor]]'s arms. ([[COMIC]]: {{cs|Ground Zero (comic story)}})]]
Like Peri, [[Ace]] died at a young age according to one account, but not others. According to one view, she died while using [[Nitro-9]] against [[Threshold]] agents known as the [[Lobri]]. Her sacrifice protected the lives of [[Sarah Jane]], [[Susan Foreman|Susan]], Peri and the [[Seventh Doctor]]. ([[DWM]]: ''[[Ground Zero]]'') According to other accounts, she lived to a much older age —at least into her late thirties. ([[NA]]: ''[[Set Piece]]'', amongst others) Unlike Peri, however, there was no evidence of Time Lord interference in her timestream, nor any indication there were actually several different, simultaneously extant Aces.
Like Peri, [[Ace]] died young according to two accounts, but not others. According to one, she died while using [[Nitro-9]] against parasitic beings known as the [[Lobri]]. Her sacrifice saved the lives of [[Sarah Jane Smith|Sarah Jane]], [[Susan Foreman|Susan]], Peri and the [[Seventh Doctor]]. ([[COMIC]]: {{cs|Ground Zero (comic story)}}) In another account she was killed by [[George Limb]], only to be replaced by a divergent version of herself, who continued to travel with the Doctor and who only had superficial differences from her other self. ([[PROSE]]: {{cs|Loving the Alien (novel)}}) Furthermore, according to other accounts, she lived to a much older age — at least into her late thirties and fifties. ([[PROSE]]: {{cs|Set Piece (novel)}}, {{cs|At Childhood's End (novel)}}, et al.)
 
[[River Song]] died physically when she linked her mind into the [[Charlotte Lux|CAL]] computer during the Doctor's first meeting with her — from his perspective; from hers, it was the last of many following an unspecified period of time as his companion. ([[TV]]: {{cs|Forest of the Dead (TV story)}}) Unknown to the [[Tenth Doctor]], River was part Time Lord due to having been conceived on board the TARDIS by the Doctor's future companions [[Amy Pond]] and [[Rory Williams]], but had given up her future regenerations to save the [[Eleventh Doctor]]'s life. ([[TV]]: {{cs|A Good Man Goes to War (TV story)}}, {{cs|Let's Kill Hitler (TV story)}}) The Doctor, therefore, proceeded with his timeline knowing how River would one day die. He gave her [[River Song's sonic screwdriver|a sonic screwdriver]] specially designed to save her mental patterns at the moment of her death in [[the Library]]. ([[TV]]: {{cs|The Husbands of River Song (TV story)}}) This allowed the earlier Tenth Doctor to upload River into CAL's immense memory bank, allowing her to live on in the computer. ([[TV]]: {{cs|Forest of the Dead (TV story)}}) She later managed to somehow link herself into a psychic "[[conference call]]" from inside CAL even as a data ghost to aid the Doctor one last time on [[Trenzalore]] before fading forever after he finally said goodbye to her. ([[TV]]: {{cs|The Name of the Doctor (TV story)}})
 
[[Kamelion]], an android companion, was destroyed by the [[Fifth Doctor]] in an act of mercy per Kamelion's own request after he was taken over by {{Ainley}}. ([[TV]]: {{cs|Planet of Fire (TV story)}})


[[River Song]] died physically when she linked her mind into the [[Charlotte Lux|CAL]] computer during her first meeting with the Doctor -- from his perspective; from hers it was the last of many following an unspecified period of time as his companion.

([[DW]]: ''[[A Good Man Goes to War]]''/''[[Let's Kill Hitler]]'') The Doctor, therefore, proceeded with his timeline knowing how River would one day die. At some point, however, he gave her a [[sonic screwdriver]] specially designed to save her mental patterns at the moment of her death in [[The Library]]. This allowed the earlier Tenth Doctor to upload River into CAL's immense memory bank, allowing her to live on in the computer. ([[DW]]: ''[[Forest of the Dead]]'')
[[Clara Oswald]], a companion of the [[Eleventh Doctor|Eleventh]] and [[Twelfth Doctor]]s, sacrificed herself for [[Rigsy]], whom she had only met once before. She was killed by a [[Quantum Shade]] after saying goodbye to the Time Lord, with the Doctor ultimately blaming [[Ashildr]] for her death. ([[TV]]: {{cs|Face the Raven (TV story)}}) The Twelfth Doctor extracted her from her timestream moments before her death using Time Lord technology, although she was frozen in between one heartbeat and her last. He realised that they couldn't continue travelling together as the [[Prophecy|prophecies]] of [[the Hybrid]] would come to pass, so he planned to erase Clara's memories of him with a [[neural block]]. However, upon discovering this, Clara attempted to reverse the polarity of the neural block so it would affect the Doctor, something he doubted had worked when she told him. They agreed to activate the device together, not knowing which one of them would be affected, and it affected the Doctor. Clara left in [[Clara's TARDIS|a stolen TARDIS]] with Ashildr to travel the universe before returning to Gallifrey and dying. ([[TV]]: {{cs|Hell Bent (TV story)}}


===== Unknown reasons =====
===== Unknown reasons =====
Very rarely, it was unknown what caused certain companions to stop travelling with the Doctor, as was true of [[Destrii]].
Very rarely, it was unknown what caused certain companions to stop travelling with the Doctor.
 
In the case of the Earthbound [[Third Doctor]], relationship timings with his occasional assistants became very unclear. Assistants in this period didn't ''stop'' travelling with him; his [[exile on Earth]] made it impossible for them to ''start'' travelling with him. ([[TV]]: {{cs|Spearhead from Space (TV story)}} - {{cs|The Three Doctors (TV story)}}) Assistants during this period tended to be people who lived in England ([[TV]]: {{cs|Spearhead from Space (TV story)}}, {{cs|Terror of the Autons (TV story)}}) whom he could meet in [[Bessie]]. Since he wasn't housing companions in the TARDIS, there wasn't a definite "moment" when an assistant entered or left "the TARDIS team". Therefore, incomplete records existed as to how long the Doctor knew certain assistants. It was never known, for example, definitively when the Doctor met or said goodbye to [[Tom Phipps]] and [[Joe (Fogbound)|Joe]]. ([[COMIC]]: {{cs|The Vortex (comic story)}}, {{cs|Fogbound (comic story)}}) Similarly, it was never known how the [[Fourth Doctor]] met or parted with [[Joan Brown]] ([[COMIC]]: {{cs|Doomcloud (comic story)}}) or [[Young (The Sea Devil)|Young]]. ([[COMIC]]: {{cs|The Sea Devil (comic story)}})
 
A similar situation occurred when the [[Eleventh Doctor]] had to guard [[Trenzalore]] for hundreds of years. Individuals such as [[Theol Willoughby]] who acted as companions did not enter or leave the TARDIS team, not least because the TARDIS was travelling in the [[Time Vortex]] for a prolonged period of time without him. Due to the extended lifespan of the Doctor, he outlived the inhabitants of [[Christmas (town)|the town]] making it impossible to determine when exactly they became companions. ([[TV]]: {{cs|The Time of the Doctor (TV story)}}, [[PROSE]]: {{cs|An Apple a Day... (short story)}})
 
===== The influence of Gallifrey =====
The [[Fourth Doctor]] lost four consecutive companions to the direct or indirect influence of Gallifrey: he was forced to leave [[Sarah Jane Smith]] on Earth on receiving an emergency summons; ([[TV]]: {{cs|The Hand of Fear (TV story)}}) [[Leela]] and [[K9 Mark I]] chose to stay on Gallifrey; ([[TV]]: {{cs|The Invasion of Time (TV story)}}) and [[Romana II]], who had been summoned to return to Gallifrey, ([[TV]]: {{cs|Full Circle (TV story)}}) escaped by remaining in [[E-Space]] with [[K9 Mark II]]. ([[TV]]: {{cs|Warriors' Gate (TV story)}}) The [[Sixth Doctor]] was also unable to save [[Peri Brown]], being transported away by the Time Lords at a crucial moment. ([[TV]]: {{cs|Mindwarp (TV story)}})
 
The warden of the [[Twelfth Doctor]]'s [[confession dial]], [[the Veil]], was actually a benevolent being, trying to help the Doctor escape during his imprisonment. It came to see itself as his companion, hoping the Doctor would take it with him to what laid beyond the dial. However, because he was unaware of the Veil's true nature, ([[PROSE]]: {{cs|The Veil (short story)}}) the Doctor displayed no sadness when the being died. ([[TV]]: {{cs|Heaven Sent (TV story)}})
 
=== Balancing travels and home ===
{{Quote|We have two lives. Real life and Doctor life. Except real life doesn't get much of a look in.|[[Rory Williams]]|The Power of Three (TV story)}}
After joining the [[Ninth Doctor]] on his travels, [[Rose Tyler]] made what was intended to be a quick stop home to see her [[mother]], [[Jackie Tyler]]. However, they found that [[the TARDIS]] had taken them 12 [[month]]s after Rose left, rather than the intended 12 [[hour]]s. ([[TV]]: {{cs|Aliens of London (TV story)}}) After being embroiled in the [[London UFO crash]], Rose left with the Doctor again. Though she told Jackie that she could be back within 10 [[second]]s, she did not return after that time elapsed. ([[TV]]: {{cs|World War Three (TV story)}}) In fact, Rose would be away from home for extended periods of time as she continued travelling with the Doctor. ([[TV]]: {{cs|Boom Town (TV story)}}, {{cs|The Parting of the Ways (TV story)}}) Following his [[regeneration]], the [[Tenth Doctor]] returned to the [[Powell Estate]] with Rose on [[Christmas Eve]]. ([[TV]]: {{cs|The Christmas Invasion (TV story)}}) Following [[Christmas]], Rose resumed her travels with the Doctor, being seen off by Jackie. ([[TV]]: {{cs|New Earth (TV story)}}) Jackie told [[Elton Pope]] that Rose [[phone|called]] her now and then but not as often as she liked, and admitted that she felt "left behind". ([[TV]]: {{cs|Love & Monsters (TV story)}})
 
[[Martha Jones]], a [[medical student]] who joined the Doctor for "one trip" in the TARDIS, ([[TV]]: {{cs|Smith and Jones (TV story)}}) was eventually returned home 12 hours after she had left, only to rejoin the Doctor that same day after the pair confronted [[Richard Lazarus]]. ([[TV]]: {{cs|The Lazarus Experiment (TV story)}}) Soon after, she made a phone call to her mother, [[Francine Jones]], who told her that it was [[election day]]. ([[TV]]: {{cs|42 (TV story)}}) Upon returning home using [[Jack Harkness's vortex manipulator]] after [[the TARDIS]] was stolen by {{Simm}}, Martha found that it was the day after the [[election]], only four days after she had met the Doctor. ([[TV]]: {{cs|The Sound of Drums (TV story)}})
 
=== Romance ===
In [[The Doctor's reality (The Curse of Fatal Death)|one future]] stemming from the [[Eighth Doctor]]'s life, ([[PROSE]]: {{cs|The Tomorrow Windows (novel)}}) the [[Ninth Doctor (The Curse of Fatal Death)|Ninth Doctor]] was engaged to be married to [[Emma (The Curse of Fatal Death)|Emma]], the only travelling companion he had ever "[[sex|had]]". However, an [[Deadly vengeance of deadly revenge|incident]] which caused the Doctor to undergo four [[regeneration]]s in quick succession resulted in Emma calling off her marriage to the female [[Thirteenth Doctor (The Curse of Fatal Death)|Thirteenth Doctor]]. ([[TV]]: {{cs|The Curse of Fatal Death (TV story)}}) The Doctor had previously married [[Romana]] during his [[Fourth Doctor|fourth incarnation]] after receiving advice from a [[Prime Computer]]. ([[TV]]: {{cs|On Through the 80's! (TV story)}})
 
Understanding that [[Jack Harkness]] was "just a bit more flexible when it [came] to dancing", the [[Ninth Doctor]] posed the question of who he would like to "dance" with, himself or [[Rose Tyler]]. ([[TV]]: {{cs|The Empty Child (TV story)}}) Before facing a [[Dalek]] [[Battle of the Game Station|attack]] on the [[Game Station]], Jack gave the Doctor a goodbye kiss. ([[TV]]: {{cs|The Parting of the Ways (TV story)}}) Having been "abandoned" by the Doctor, ([[AUDIO]]: {{cs|Piece of Mind (audio story)}}) Jack was recorded as saying that, when he found the Doctor, he would [[kiss]] him before killing him. ([[TV]]: {{cs|Fragments (TV story)}}) When he saw that [[Martha Jones]] "fancied" the [[Tenth Doctor]], Jack asked "you too, huh?" ([[TV]]: {{cs|The Sound of Drums (TV story)}}) Mistakenly believing [[Graham O'Brien]] to be a new [[incarnation]] of the Doctor, Jack described him as "still sexy". ([[TV]]: {{cs|Fugitive of the Judoon (TV story)}})
 
Martha Jones grew to fall in love with the Doctor as she travelled with him, ([[TV]]: {{cs|The Sound of Drums (TV story)}}) and it was her knowledge that he would not reciprocate her feelings that led her to leave the TARDIS for home, as well as the impact the [[The Year That Never Was]] had on her family. ([[TV]]: {{cs|Last of the Time Lords (TV story)}})

Acknowledging that his time with Martha got "complicated", the Doctor told [[Donna Noble]] that he just wanted "a [[mate]]". Donna, who had misheard the Doctor as saying that he wanted "to [[mating|mate]]", expressing her disgust and rejection of such a prospect. ([[TV]]: {{cs|Partners in Crime (TV story)}}) The Doctor and Donna were mistaken for a married couple on multiple instances, a misconception which they were quick to correct. ([[TV]]: {{cs|The Fires of Pompeii (TV story)}}, {{cs|Planet of the Ood (TV story)}}, {{cs|The Unicorn and the Wasp (TV story)}})

Other [[Time Lord]]s had companions in their travels. Before his final corruption into the renegade known as [[the Master]], the Time Lord [[Koschei]] was accompanied in his hunt for the Doctor by [[Ailla]]. Koschei believed Ailla a young woman from a [[28th century]] Earth colony, but she was in fact a Time Lady agent sent by the [[High Council of Time Lords|High Council]] to spy on his increasingly erratic behaviour. ([[MA]]: ''[[The Dark Path]]'') In his battle with the newly [[regenerated]] [[Eighth Doctor]], the Master was assisted by [[Chang Lee]], a young man in [[1999]] [[San Francisco]]. Lee had been convinced by the Master that the Doctor was evil. Only too late did he learn the truth when the Master killed the boy, although the Doctor subsequently restored him to life.

{{Ainley|c}} that joined with [[Tremas]] had control over [[Kamelion]] for a time. He used him to escape [[Xeriphas]] and to impersonate [[King John]]. However, the Doctor freed him from the Master's control and invited him to join the TARDIS crew, which he did. ([[TV]]: {{cs|The King's Demons (TV story)}}) The Master later regained control over him, causing Kamelion to persuade the Doctor to destroy him. ([[TV]]: {{cs|Planet of Fire (TV story)}})
 
The Tremas Master also briefly bribed [[Sabalom Glitz]] to help him in his schemes and betray the Doctor although the Master was tricked by [[the Valeyard]], ending his plan. ([[TV]]: {{cs|The Ultimate Foe (TV story)}}) According to one account, [[Christopher Marlowe]]'s death was prevented by the Master who took him away from [[Deptford]] shortly before he was scheduled to die. He travelled with the Master for some time before returning and accepting his fate. ([[PROSE]]: {{cs|Master Faustus (short story)}}) This Master also possessed an [[The Master (Auton)|Auton duplicate]] that obeyed his commands.

During the [[Last Great Time War]], [[the Master]] took on [[Cole Jarnish]] as a companion. ([[AUDIO]]: {{cs|The Good Master (audio story)}}) However, this was nothing more than a ruse and he killed him once his usefulness had come to an end. ([[AUDIO]]: {{cs|The Heavenly Paradigm (audio story)}}) {{Jacobi|n=As Professor Yana}}, the Master worked with [[Chantho]], who in many ways could be considered his companion. However, after regaining memories of his previous incarnations, the Master killed Chantho. ([[TV]]: {{cs|Utopia (TV story)}})

* It is unknown what exactly caused the [[Eighth Doctor]]'s companion [[Destrii]]'s departure from the TARDIS. The start of the [[Ninth Doctor]]'s era on television meant that the Eighth Doctor comics were coming to an end. With a reluctance to kill her off in her final appearance in the strip she simply stopped appearing. Destrii reappeared in ''[[The Stockbridge Showdown (comic story)|The Stockbridge Showdown]]'' although her departure remained unaddressed.
=== What does the word "companion" actually mean? ===
=== What does the word "companion" actually mean? ===
By definition, the word companion means: someone who travels willingly with The Doctor in his TARDIS. The term "companion" is used more outside the programme — which is to say in [[wiktionary:fandom|fandom]] —than within the narrative. It was especially rarely used in the original version of the television programme, and practically never uttered by the Doctor himself. "Assistant" was a far more common designation — being used, for instance, by the [[First Doctor]] to describe [[Dodo Chaplet]] in ''[[The War Machines]]'', by [[the Brigadier]] to introduce [[Jo Grant]] in ''[[Terror of the Autons]]'', and by the [[Fifth Doctor]] to jog the Brig's memory of Jo in ''[[Mawdryn Undead]]''. However, "companion" has been heard with greater regularity in the [[BBC Wales]] version, beginning with the [[Ninth Doctor]]'s claim to [[London]] [[police]] that he had "employed [Rose] as my companion". ([[DW]]: ''[[Aliens of London]]'') The term is also encountered in other media, such as the Tenth Doctor's comment "Wow, I really need a companion". ([[IDW]]: ''[[Ground Control]]'') The [[Eleventh Doctor]] asked [[Val (Closing Time)|Val]] if 'partner' was better than companion, not realising she meant it as a term for a homosexual couple. ([[DW]]: ''[[Closing Time]]'')
[[File:All the Doctor's companions caught.jpg|thumb|[[Adam Mitchell]] kidnapped a number of the Doctor's companions ([[COMIC]]: ''[[The Choice (comic story)|The Choice]]'')]]
The term "companion" is used more outside the programme — which is to say in [[wiktionary:fandom|fandom]] — than within the narrative. It was especially rarely used in the original version of the television programme. While the [[First Doctor]] referred to [[Ian Chesterton]] as "one of [his] companions" as early as ''[[The Daleks (TV story)|The Daleks]]'', it was practically never uttered by the Doctor himself until the [[John Nathan-Turner]] [[producer]]ship. "Assistant" was a far more common designation — being used, for instance, by the [[First Doctor]] to describe [[Dodo Chaplet]] in ''[[The War Machines (TV story)|The War Machines]]'', by [[the Brigadier]] to introduce [[Jo Grant]] in ''[[Terror of the Autons (TV story)|Terror of the Autons]]'' and by the [[Fifth Doctor]] to jog the Brig's memory of Jo in ''[[Mawdryn Undead (TV story)|Mawdryn Undead]]''. However, "companion" has been heard with greater regularity in other media — particularly that written since the transmission of ''[[Survival (TV story)|Survival]]''.
 
Indeed, [[Big Finish Productions]] have an entire range of product called ''[[The Companion Chronicles]]'', which focuses on telling ''Doctor Who'' adventures from the perspective of the assistant. Equally, ''[[Doctor Who Magazine]]'' have taken to labelling the role that of "companion" — as they did on the cover of [[DWM 446]], when they announced the arrival of [[Jenna-Louise Coleman]]. The tacit assumption between ''DWM'' editors and their readers is that, somehow, both groups know what the other is talking about — as if the word ''companion'' were a title whose qualifications and responsibilities were well defined. However, this is not the case.
 
Neither ''assistant'' nor ''companion'' have ever been unambiguously defined in a narrative. Without a solid [[in-universe]] definition, viewers are left to struggle with the term on their own. At what point, they are forced to ask themselves, does a supporting character become a "companion"? Is it when they travel in [[the TARDIS]]? If so, then [[Liz Shaw]] isn't a companion, despite being the clear co-star of [[Season 7 (Doctor Who 1963)|an entire season]]. Is it when they're in more than one story? If so, then [[Sara Kingdom]], [[Christina de Souza]], [[Jackson Lake]], [[Adelaide Brooke]], [[Wilfred Mott]] and [[Astrid Peth]] must be struck from the list, despite the fact that their respective actors were given star billing in their respective episodes (Kingdom excluded as she was featured in a 1960s story, long before "star billing"). Can [[Jackie Tyler]] be considered a companion, since she appeared in numerous stories ''and'' she travelled in the TARDIS, ''and'' she even helped the Doctor recover after a [[regeneration]]?


This conflicting approach to naming was meta-textually referenced in ''[[School Reunion]]'', when [[Sarah Jane]], an old-series character, called Rose the Doctor's "new assistant". Rose flatly eschewed the term, but Sarah clearly believed Rose was just fooling herself.
Meta-fictional and story considerations are also a problem. [[Canton Everett Delaware III]] spent three months assisting the Doctor, travelled in the TARDIS at least once, and encountered him again forty years later, yet lack of star billing and the fact his time with the Doctor is shown over only two episodes puts his status in dispute.
[[File:The Brig.jpg|thumb|Is [[the Brig|this man]] a companion?  He's travelled in [[the TARDIS]], nursed two Doctors back to health after [[regeneration]]s, and given the Doctor a home when [[Time Lord|his own people]] didn't want him anymore.  But he didn't ''regularly'' travel by TARDIS, and he's never been called a companion in a televised story.]]
Nevertheless, ''neither'' term is particularly common within the narrative. Without a solid [[in-universe]] definition, viewers are left to struggle with the term on their own.

Can [[Jackie Tyler]] be considered a companion, since she appeared in lots of stories ''and'' she travelled in the TARDIS, ''and'' she even helped the Doctor recover after a [[regeneration]]?

Then there are behind-the-scenes concerns. If an actor like [[Jean Marsh]] tells us flatly that she was not hired as a companion ([[BFX]]: ''[[The Drowned World]]'', [[DOC]]: ''[[From Kingdom to Queen]]'') and the official BBC website's own list of companions does not include her, is it reasonable to consider [[Sara Kingdom]] a companion? If her, why not [[Bret Vyon]], who also appeared in several episodes of [[TV]]: ''[[The Daleks' Master Plan (TV story)|The Daleks' Master Plan]]'' fulfilling a function nearly identical to Sara? In a similar vein, the early story [[TV]]: ''[[The Keys of Marinus (TV story)|The Keys of Marinus]]'' features two characters, [[Altos]] and [[Sabetha]], who non-ambiguously joined the TARDIS crew as companions for the course of the single adventure, although they never rode in the TARDIS itself; do they have as valid a claim to being companions as Christina de Souza, who likewise never set foot in the TARDIS during her single adventure?

This question can be expanded to the literally hundreds of characters depicted on TV, in comic strips and in literature who over the years have filled companion-like roles in one-off stories as they encountered the Doctor. Indeed some of these characters have been promoted to ersatz companion status. For a time, [[Henry Gordon Jago]] and [[George Litefoot]] could be described as just this; one-off characters from [[TV]]: ''[[The Talons of Weng-Chiang (TV story)|The Talons of Weng-Chiang]]'' who, decades later, were featured in an edition of the [[Big Finish Productions]] audio series, ''[[The Companion Chronicles]]'', and later given [[Jago and Litefoot|their own spin-off series]]. However, they travelled with the Sixth Doctor in [[AUDIO]]: ''[[Voyage to Venus (audio story)|Voyage to Venus]]'' and ''[[Voyage to the New World (audio story)|Voyage to the New World]]'', making their status as companions less controversial.

All these question marks! Determining who is a companion and who is not is one of the most common fan debates. It is possible by the fact that the television programme itself offers no definition for the term. Though probably exacerbated by the [[BBC Wales]] version's greater narrative flexibility, the debate is hardly a new one. It's been going on for ages, fuelled in previous decades by officially licensed reference works that helped mould fan opinion. For instance, [[the Brigadier]], one of the people whose companion status is most hotly contested, gets some support for his alleged "companion status" from the book ''[[The Making of Doctor Who]]'', in which two of the main writers of his era of the programme unambiguously called him a companion. Likewise, the later [[John Nathan-Turner]] book, ''[[The Companions (reference book)|The Companions]]'' was influential in making [[1980s]] fans remember [[Sara Kingdom]] and for enshrining her as a companion — albeit against evidence in the BBC archives.

Still, though the new series put the ''term'' "companion" on more solid narrative ground, it greatly confuses the definition. {{quote|. . . what constitutes a ''Doctor Who'' companion is no longer clear. Sure, Rose, Martha and Donna were all companions. So was Captain Jack. But what about Mickey and Jackie? How do you qualify? Name in the opening credits, regular trips in the Tardis?

Still, though the new series put the ''term'' "companion" on more solid narrative ground — even two [[British Prime Minister|Prime Ministers]] had used it by the end of the [[RTD]] era —it greatly confuses the definition. {{quote|. . . what constitutes a ''Doctor Who'' companion is no longer clear.

In truth, though, it's ''never'' been very clear, even from a behind-the-scenes perspective. Though BBC Wales have confused things by putting single-episode guest stars in the opening credits, the "classic" series sowed similar confusion by often not listing "companions" very high in the credit list. Any definition of ''companion'' as "co-star" falls apart in the classic era, because companions were often listed ''after'' guest stars — sometimes after ''several'' guest stars. And claims that they were "regulars" must be counterbalanced against the fact that they were often contracted only for a matter of weeks, and lived under the threat of being unceremoniously dismissed mid-[[serial]], like [[Jackie Lane]] was.

This narrative uncertainty makes it difficult for ''this wiki'' to consistently use the term. Several forum debates have raged as to how the term should be applied, including [[Forum:Disputed Companions|Disputed Companions]] and [[Forum:Who counts as a companion?|Who counts as a companion?]]. Those readers wishing to understand why certain companions are included on certain lists that appear on this site may want to explore those discussions.

In televised ''[[Doctor Who]]'', actors who played companions rarely stayed more than a series. Though some companions had notably long runs, they were the exception more than the rule. Discounting companions like [[Astrid Peth]] and [[Sara Kingdom]] — each of whom appeared in only a single story — record-holders for shortest run include [[Katarina]] and [[Adam Mitchell]]. Each appeared in only about two hours of televised ''Doctor Who''. [[Dodo Chaplet]] also had an atypically short run of only sixteen twenty-five-minute episodes. Some companions who seemed to be around for a fair number of seasons, in fact had relatively few stories to their name. The classic example is [[Ace]], who was only in nine stories — one fewer than the number of stories in the typical [[BBC Wales]] series. Even when compared with classic series-only companions, Ace isn't all that "wicked". [[Polly Wright|Polly]] and [[Ben Jackson|Ben]] were in as many adventures in less than half the time. Because Ace was only in a mere thirty-one episodes, even [[Susan Foreman|Susan]] easily bests her.

[[File:Fieldj22.jpg|thumb|[[Tegan]] is the current record holder for longest continuous period of time on ''[[Doctor Who]]'' ]]
Record-holders for ''longest'' tenures can be measured in a number of different ways.
* In terms of consecutive individual episodes, [[Jamie McCrimmon]] is the easy winner with one hundred and thirteen episodes between [[DW]]: ''[[The Highlanders]]'' and ''[[The War Games]]'', outdistancing most Doctors, much less all other companions. He served for the better part of three seasons, during which ''Doctor Who'' had its highest episode count. Due to changed television consumption habits, that record will almost certainly never be approached, much less broken. (Note that the above number doesn't take into account episodes where he's travelling with the Doctor but Frazer Hines or Hamish Wilson doesn't appear on screen. The number also increases to  one hundred and sixteen if one includes his later return in [[DW]]: ''[[The Two Doctors]]'')
* In terms of stories, given that [[BBC Wales]] has a much higher story count than the original series, the high water mark has so far been set by [[Rose Tyler]]. Discounting flashbacks and her two "blink and you'll miss her" cameos in [[DW]]: ''[[The Poison Sky]]'' and ''[[Midnight (TV story)|Midnight]]'', Rose appeared in a total of twenty-six individual stories; this includes the [[DW]]: ''[[Children in Need Special]]'' mini-episode and her more substantial cameos in [[DW]]: ''[[Partners in Crime]]'' and ''[[The End of Time (TV story)|The End of Time]]''.
* In terms of calendar time that the public would have perceived a character as being a regular on ''Doctor Who'', the winner is [[Tegan]]. She clocks in at three days shy of three years, from her first to last regular appearances. She only very narrowly defeats [[Sarah Jane]], who is some six weeks shy of three years as a regular character. Note that calendar years are not the same thing as seasons, because ''Doctor Who'' did not begin its seasons on the same date each year (it should be noted, however, that Tegan as of 2011 is the only travelling companion to appear during four consecutive seasons as a regular). Special mention should be given here, too, to the character of [[Alistair Gordon Lethbridge-Stewart|the Brigadier]]. It's entirely possible that some members of the viewing community regarded him as at least a kind of regular throughout all five seasons of [[Jon Pertwee]]'s ''Doctor Who''. Although this isn't true from a contractual standpoint, he's still an incredibly long-serving member of the cast. Regular or not, the character appeared in more episodes of the programme than all of the [[1980s]] Doctors except [[Tom Baker]].
* If the [[The Doctor's TARDIS|Doctor's TARDIS]] is considered as a companion (see below), she tops all categories, having been a constant in the series since 23rd November 1963 and being ubiquitous across all media with the notable exception of the early [[Third Doctor]] era when the TARDIS was not featured regularly due to the Doctor's exile to Earth, as well as the [[Fourth Doctor]] stories ''[[The Sontaran Experiment]]'' and ''[[Genesis of the Daleks]]'' and the [[Tenth Doctor]] story ''[[Midnight (TV story)|Midnight]]''.


=== The Doctor's TARDIS as companion ===
Discounting companions like [[Astrid Peth]] and [[Sara Kingdom]] — each of whom appeared in only a single story — the record-holder for the shortest run would be [[Adam Mitchell]]. He appeared in only two stories or about 90 minutes of televised ''Doctor Who'', spread across eight days of real-world time.
In the wake of the revelations made in [[DW]]: ''[[The Doctor's Wife]]'' - not the least of which is the confirmation, long implied and assumed, that the TARDIS, if not itself sentient, was controlled by a sentient consciousness - a school of thought has been established that considers the Doctor's TARDIS to be not simply a travelling vessel, but an actual companion. Although this fact has yet (as of 2011) to be stated explicitly on screen, it has been referenced in reviews ([http://www.hitfix.com/blogs/whats-alan-watching/posts/doctor-who-the-doctors-wife-neil-gaiman-brings-good-things-to-life such as this example]), in the ''[[Doctor Who Confidential]]'' episode "Bigger on the Inside", and by episode writer Neil Gaiman and producer Steven Moffat in the pages of ''[[Doctor Who Magazine]]''.
[[File:PC Yasmin Khan (TWWFTE).jpg|thumb|[[Yasmin Khan|Yaz]] is the current record holder for longest continuous period of time on ''[[Doctor Who]]''.]]
Record-holders for ''longest'' tenures can be measured in different ways.
* In terms of individual episodes, [[Jamie McCrimmon]] is the easy winner with 113 episodes between ''[[The Highlanders (TV story)|The Highlanders]]'' and ''[[The War Games (TV story)|The War Games]]'', outdistancing most Doctors, much less all other companions. He served for the better part of three seasons, during which ''Doctor Who'' had its highest episode count. Due to changed television consumption habits, that record will almost certainly never be approached, much less broken. (Note that the above number doesn't take into account episode 4 of ''[[The Enemy of the World (TV story)|The Enemy of the World]]'' where Jamie is still travelling with the Doctor but neither [[Frazer Hines]] nor [[Hamish Wilson]] appear on screen. Were that to be accounted for, Jamie would have two consecutive episode totals of 48 and 64, respectively. The total number increases to 116 if one includes his later return in ''[[The Two Doctors (TV story)|The Two Doctors]]''; Hines' appearance as Jamie in ''[[The Five Doctors (TV story)|The Five Doctors]]'' is not included as he was only playing an apparition and not the actual character.)
* In terms of stories, given that [[BBC Wales]] has a much higher story count (per season) compared to the original series, the high water mark has been set by [[Clara Oswald]], appearing in 30 full-length televised stories from ''[[The Snowmen (TV story)|The Snowmen]]'' on 25 December 2012 to her exit in ''[[Hell Bent (TV story)|Hell Bent]]'' on 5 December 2015. Actor [[Jenna Coleman]] also appeared as an echo of Clara prior to ''The Snowmen'' in ''[[Asylum of the Daleks (TV story)|Asylum of the Daleks]]'', and as part of the [[Testimony]] (Clara's memory) later on in ''[[Twice Upon a Time (TV story)|Twice Upon a Time]]''.
* In terms of calendar time that the public would have perceived a character as being a regular on ''Doctor Who'', the winner is [[Yasmin Khan]], with a period of four years and 16 days from her first regular appearance in ''[[The Woman Who Fell to Earth (TV story)|The Woman Who Fell to Earth]]'' on 7 October 2018 to her last regular appearance in ''[[The Power of the Doctor (TV story)|The Power of the Doctor]]'' on 23 October 2022. Note that calendar years are not the same thing as seasons, as ''Doctor Who'' has not consistently begun its seasons on the same date or even month each year. Also, during Yasmin's tenure her three-series run aired in 2018, 2020, and 2021, with 2019 having a single [[New Year Special]], ''[[Resolution (TV story)|Resolution]]'', and her final three episodes in 2022 consisting of New Year Special ''[[Eve of the Daleks (TV story)|Eve of the Daleks]]'', [[Easter Special]] ''[[Legend of the Sea Devils (TV story)|Legend of the Sea Devils]]'', and BBC [[Centenary Special]] ''The Power of the Doctor''.
* In terms of the number of Doctors spanned, [[Donna Noble]] holds the record having been the regular companion of both the [[Tenth Doctor]] beginning on 5 April 2008 (after her first encounter with him in ''[[The Runaway Bride (TV story)|The Runaway Bride]]'' 2006 Christmas episode) and the [[Fourteenth Doctor]] ending on 9 December 2023, albeit with almost a decade and a half hiatus between each role.
* In terms of length of incumbency, [[Ace]] is easily the record-holder, having joined the Doctor in 1987's ''[[Dragonfire (TV story)|Dragonfire]]'' and ceasing to be the incumbent companion by default nine years later when the 1996 [[Doctor Who (TV story)|TV Movie]] depicted the Seventh Doctor traveling alone.
* In terms of season count, [[Tegan Jovanka]] and [[Sarah Jane Smith]] are, {{as of|2022|12|lc=y}}, the only travelling companions to appear during four consecutive seasons as a regular, having appeared in [[Season 18 (Doctor Who 1963)|seasons 18]] to [[Season 21 (Doctor Who 1963)|21]] and [[Season 11 (Doctor Who 1963)|seasons 11]] to [[Season 14 (Doctor Who 1963)|14]] respectively. Only [[Jo Grant]], Sarah Jane, and Yaz appeared in three ''complete'' seasons, namely [[Season 8 (Doctor Who 1963)|seasons 8]] to [[Season 10 (Doctor Who 1963)|10]]; [[Season 11 (Doctor Who 1963)|seasons 11]] to [[Season 13 (Doctor Who 1963)|13]]; and [[Series 11 (Doctor Who 2005)|''series'' 11]] to [[Series 13 (Doctor Who 2005)|13]] of the BBC Wales/[[BBC Studios]] revival series.
Special mention should also be given here to the character of [[Alistair Gordon Lethbridge-Stewart|the Brigadier]], who was an incredibly long-serving member of the cast. Regular or not, the character as played by [[Nicholas Courtney]] appeared in more episodes of the programme than all of the 1980s Doctors except [[Tom Baker]], from ''[[The Web of Fear (TV story)|The Web of Fear]]'' Episode 3 on 17 February 1968 to ''[[Battlefield (TV story)|Battlefield]]'' Part Four on 27 September 1989, 21 years and 7 months later.

Four of the Doctor's companions were, from top left and in clockwise order: his granddaughter, Susan; Stockbridge science fiction fan Izzy Sinclair; his first companion after the Last Great Time War, Rose Tyler; and the Second Doctor's most constant companion, Highland Scot, Jamie McCrimmon.

Companion was a somewhat vague term used to describe the Doctor's closest friends. (AUDIO: Situation Vacant [+]Loading...["Situation Vacant (audio story)"], No Place Like Home [+]Loading...["No Place Like Home (audio story)"], Death and the Queen [+]Loading...["Death and the Queen (audio story)"]) Such people knew the Doctor's "secret": that they were someone non-human who travelled in time and space in a police box-shaped craft called the TARDIS. The Doctor's companions often directly saved the Doctor's lives (TV: Rose [+]Loading...["Rose (TV story)"], The Family of Blood [+]Loading...["The Family of Blood (TV story)"]) or provided the Doctor with a perspective that prevented them from abusing their Time Lord powers. (AUDIO: To the Death [+]Loading...["To the Death (audio story)"], TV: School Reunion [+]Loading...["School Reunion (TV story)"], The Runaway Bride [+]Loading...["The Runaway Bride (TV story)"], The Fires of Pompeii [+]Loading...["The Fires of Pompeii (TV story)"]) On some occasions, they were the proximate reason that the Doctor sacrificed their then-current life and regenerated. (TV: The Caves of Androzani [+]Loading...["The Caves of Androzani (TV story)"], The Parting of the Ways [+]Loading...["The Parting of the Ways (TV story)"], The End of Time [+]Loading...["The End of Time (TV story)"]) On others, they lost their lives in pursuit of the Doctor's goals. (TV: "The Traitors" [+]Part of The Daleks' Master Plan, Loading...{"namedep":"The Traitors (4)","1":"The Daleks' Master Plan (TV story)"}, "Destruction of Time" [+]Part of The Daleks' Master Plan, Loading...{"namedep":"Destruction of Time (12)","1":"The Daleks' Master Plan (TV story)"}, Earthshock [+]Loading...["Earthshock (TV story)"], Voyage of the Damned [+]Loading...["Voyage of the Damned (TV story)"], Face the Raven [+]Loading...["Face the Raven (TV story)"], AUDIO: Absolution [+]Loading...["Absolution (BFM audio story)"], To the Death [+]Loading...["To the Death (audio story)"])

The Eleventh Doctor told Amy Pond he travelled with companions to see the universe through the eyes of somebody who hadn't experienced it all already. (HOMEVID: Meanwhile in the TARDIS [+]Loading...["Meanwhile in the TARDIS (home video)"]) He also mentioned that he took great care in choosing them. (TV: Amy's Choice [+]Loading...["Amy's Choice (TV story)"]) Once they left the Doctor's company, most companions used their newfound perspective of life and morality to help others; Sarah Jane Smith once noted that with them around "the Doctor" - their ideology and legacy - would never die. (TV: Death of the Doctor [+]Loading...["Death of the Doctor (TV story)"]) Rose Tyler felt she had learned a "better way of living life" from her time spent with the Ninth Doctor, and earned a new resolve to take action, to make a stand when things needed changing. (TV: The Parting of the Ways [+]Loading...["The Parting of the Ways (TV story)"]) The companions also helped the Doctor in their battles against evil throughout time and space. (TV: The Ultimate Foe [+]Loading...["The Ultimate Foe (TV story)"]) In particular, Ace called the Daleks "the catch" to being a companion, (AUDIO: Enemy of the Daleks [+]Loading...["Enemy of the Daleks (audio story)"]) while Clara Oswald described them as a companion's deadliest foe. (PROSE: The Companion's Companion [+]Loading...["The Companion's Companion (novel)"])

Because the term was a shortening of the expression "travelling companion", most companions did in fact voyage with the Doctor in the TARDIS. Depending on the situation, other words were used to describe the same relationship — most frequently, "assistant". However, it was unusual to hear the Doctor call their friends by either word. Different incarnations had different preferences. The Third Doctor, perhaps owing to his unique situation of exile, most frequently used the term "assistant". (TV: The Ambassadors of Death [+]Loading...["The Ambassadors of Death (TV story)"], Terror of the Autons [+]Loading...["Terror of the Autons (TV story)"]) On the other hand, when the Eighth Doctor was forced to define the word companion, he eschewed the term assistant in favour of friend. (AUDIO: Situation Vacant [+]Loading...["Situation Vacant (audio story)"]) Sarah Jane once implied the Doctor's companions served as a surrogate family for them, despite the Time Lord's insistence that they were alone in the universe. (TV: Journey's End [+]Loading...["Journey's End (TV story)"]) Martha Jones even stated the Doctor took on companions to ease their loneliness. (TV: The Family of Blood [+]Loading...["The Family of Blood (TV story)"])

Both terms were occasionally troublesome. Sometimes, the word companion was interpreted sexually, leading to confusion about the Doctor's relationship with their friends. (TV: Aliens of London [+]Loading...["Aliens of London (TV story)"], Closing Time [+]Loading...["Closing Time (TV story)"]) Sometimes, companions bickered over the appropriateness of the word assistant. Rose Tyler said emphatically, "I'm not his assistant" when Sarah Jane Smith called her one. (TV: School Reunion [+]Loading...["School Reunion (TV story)"]) Rose seemed happier being called a "companion", as when Harriet Jones called out over the Sub-Wave Network for "former companions of the Doctor". (TV: The Stolen Earth [+]Loading...["The Stolen Earth (TV story)"]) Donna Noble was not too keen on being referred to as a companion, thinking it sounded as if "[they] park [the Doctor] on the seafront at Weston-super-Mare". (TV: The Giggle [+]Loading...["The Giggle (TV story)"])

Another term was associate, which was used primarily by the Daleks. (TV: The Parting of the Ways [+]Loading...["The Parting of the Ways (TV story)"], The Big Bang [+]Loading...["The Big Bang (TV story)"], The Witch's Familiar [+]Loading...["The Witch's Familiar (TV story)"]) The Eleventh Doctor himself once introduced Clara Oswald to Mother Superious Tasha Lem as his associate. (TV: The Time of the Doctor [+]Loading...["The Time of the Doctor (TV story)"])

People were companions or assistants to the Doctor for varying lengths of time, but most stayed with him for more than one adventure. (TV: An Unearthly Child [+]Loading...["An Unearthly Child (TV story)"], The Daleks [+]Loading...["The Daleks (TV story)"], The Rescue [+]Loading...["The Rescue (TV story)"], The Romans [+]Loading...["The Romans (TV story)"], The Chase [+]Loading...["The Chase (TV story)"], The Time Meddler [+]Loading...["The Time Meddler (TV story)"], et al.) Some stayed for a few days, while others were with them for years. (AUDIO: No Place Like Home [+]Loading...["No Place Like Home (audio story)"], Absent Friends [+]Loading...["Absent Friends (audio story)"]) On occasion, companions could be separated from the Doctor for months or years before they resumed travelling with them. (TV: The Doctor, the Widow and the Wardrobe [+]Loading...["The Doctor, the Widow and the Wardrobe (TV story)"], AUDIO: The Juggernauts [+]Loading...["The Juggernauts (audio story)"]) Other Time Lords, usually renegades, sometimes had travelling companions.

Companions of the Doctor[[edit] | [edit source]]

Demographics[[edit] | [edit source]]

Humans[[edit] | [edit source]]

Four of the Doctor's companions - all female humans from varying times. (AUDIO: Ravenous 3)

In the main, the Doctor travelled with humans, mostly from the 20th and 21st centuries. (TV: "An Unearthly Child" [+]Part of An Unearthly Child, Loading...{"namedep":"An Unearthly Child (1)","1":"An Unearthly Child (TV story)"}, "Bell of Doom" [+]Part of The Massacre, Loading...{"namedep":"Bell of Doom (4)","1":"The Massacre (TV story)"}, The War Machines [+]Loading...["The War Machines (TV story)"], The Wheel in Space [+]Loading...["The Wheel in Space (TV story)"], Rose [+]Loading...["Rose (TV story)"], Dalek [+]Loading...["Dalek (TV story)"], School Reunion [+]Loading...["School Reunion (TV story)"], et al.) Their fondness for humans was one of the reasons they were exiled to Earth by the Time Lords. (TV: The War Games [+]Loading...["The War Games (TV story)"]) Despite the Doctor claiming to be all alone, Sarah Jane Smith told the Tenth Doctor that he had the biggest family in the universe: them. (TV: Journey's End [+]Loading...["Journey's End (TV story)"])

Most of the Doctor's human companions were from either the mid-late 20th century (TV: "An Unearthly Child" [+]Part of An Unearthly Child, Loading...{"namedep":"An Unearthly Child (1)","1":"An Unearthly Child (TV story)"}, "Bell of Doom" [+]Part of The Massacre, Loading...{"namedep":"Bell of Doom (4)","1":"The Massacre (TV story)"}, The War Machines [+]Loading...["The War Machines (TV story)"], The Time Warrior [+]Loading...["The Time Warrior (TV story)"], et al.) or the early 21st century. (TV: Rose [+]Loading...["Rose (TV story)"], Smith and Jones [+]Loading...["Smith and Jones (TV story)"], Partners in Crime [+]Loading...["Partners in Crime (TV story)"], et al.) The vast majority of companions from this time period were either English or picked up by the Doctor in England. There were exceptions to this, however. The American Peri Brown met the Doctor whilst holidaying in Lanzarote. (TV: Planet of Fire [+]Loading...["Planet of Fire (TV story)"])

Gender[[edit] | [edit source]]

Amongst the Doctor's human companions, a high number of them were young women — a fact the Eleventh Doctor once tried sheepishly to hide from Amy Pond. (HOMEVID: Meanwhile in the TARDIS [+]Loading...["Meanwhile in the TARDIS (home video)"])

Steven Taylor was a rarity — a male human who, after Sara Kingdom's death, travelled with the Doctor for a period of time when there were no female companions.

It was the First Doctor who first had multiple adventures exclusively with a man from Earth, Steven Taylor. (TV: The Massacre [+]Loading...["The Massacre (TV story)"], PROSE: Roses [+]Loading...["Roses (short story)"], Making History [+]Loading...["Making History (short story)"], Waiting for Jeremy [+]Loading...["Waiting for Jeremy (short story)"]) The Doctor's second incarnation was never long without Jamie McCrimmon at his side, (COMIC: Action in Exile [+]Loading...["Action in Exile (comic story)"] - The Night Walkers [+]Loading...["The Night Walkers (comic story)"], PROSE: World Game [+]Loading...["World Game (novel)"], Golem [+]Loading...["Golem (short story)"], Blue Road Dance [+]Loading...["Blue Road Dance (short story)"], Scientific Adviser [+]Loading...["Scientific Adviser (short story)"], That Time I Nearly Destroyed the World Whilst Looking for a Dress [+]Loading...["That Time I Nearly Destroyed the World Whilst Looking for a Dress (short story)"], Mother's Little Helper [+]Loading...["Mother's Little Helper (short story)"], Reunion [+]Loading...["Reunion (ST short story)"], Dust [+]Loading...["Dust (short story)"]) even after his trial with the Time Lords. (PROSE: The Time Eater [+]Loading...["The Time Eater (short story)"], COMIC: Invasion of the Quarks [+]Loading...["Invasion of the Quarks (comic story)"] to Martha the Mechanical Housemaid [+]Loading...["Martha the Mechanical Housemaid (comic story)"])

The Fifth Doctor also adventured with a World War II American pilot, Gus, (COMIC: 4-Dimensional Vistas [+]Loading...["4-Dimensional Vistas (comic story)"] - The Moderator [+]Loading...["The Moderator (comic story)"]) and the Eighth Doctor may have travelled solo with his long-term companion, Fitz Kreiner. (PROSE: Escape Velocity [+]Loading...["Escape Velocity (novel)"])

The Doctor's relationship with their companions usually remained platonic, though gender as well as sexuality could play a role in romantic or sexual feelings being harboured in either direction.

The Eighth Doctor described beginning to feeling sexual and romantic urges for the first time, but found it important to stress to I.M. Foreman that it wouldn’t be fair on any of his companions for them to get involved with him. (PROSE: Interference - Book Two [+]Loading...["Interference - Book Two (novel)"])

Despite this acknowledged power dynamic, (PROSE: Interference - Book Two [+]Loading...["Interference - Book Two (novel)"]) there were some encounters between the Eighth Doctor and his companions. In fact, Bernice Summerfield recalled having sex with him soon after his regeneration. (AUDIO: Benny's Story [+]Loading...["Benny's Story (audio story)"], PROSE: The Dying Days [+]Loading...["The Dying Days (novel)"])

The Ninth and Tenth Doctors shared a relationship with Rose Tyler which appeared romantic to outside observers, such as Mickey Smith, (TV: Boom Town [+]Loading...["Boom Town (TV story)"], School Reunion [+]Loading...["School Reunion (TV story)"], Rise of the Cybermen [+]Loading...["Rise of the Cybermen (TV story)"], Doomsday [+]Loading...["Doomsday (TV story)"]) Martha Jones (TV: The Sound of Drums [+]Loading...["The Sound of Drums (TV story)"]) and Donna Noble. (TV: Journey's End [+]Loading...["Journey's End (TV story)"])

Later on, the Eleventh Doctor married his on-and-off companion River Song, in a ceremony both parties recognised as binding, (TV: The Wedding of River Song [+]Loading...["The Wedding of River Song (TV story)"], The Angels Take Manhattan [+]Loading...["The Angels Take Manhattan (TV story)"], The Husbands of River Song [+]Loading...["The Husbands of River Song (TV story)"], HOMEVID: Last Night [+]Loading...["Last Night (home video)"], et al.) and which carried through to the Doctor’s other incarnations, even as they met out of order. (TV: The Husbands of River Song [+]Loading...["The Husbands of River Song (TV story)"], AUDIO: My Dinner with Andrew [+]Loading...["My Dinner with Andrew (audio story)"])

Romantic feelings were not always reciprocated. Martha Jones was in love with the Doctor but was rebuffed. (TV: Last of the Time Lords [+]Loading...["Last of the Time Lords (TV story)"]) Equally, Amy Pond was sexually interested in the Doctor but was firmly rejected. (TV: Flesh and Stone [+]Loading...["Flesh and Stone (TV story)"]) When exposed to a Truth Field in the presence of the Eleventh Doctor, Clara Oswald blurted out "I'm an English teacher from the planet Earth, and I've run off with a man from space because I really fancy..." She cut herself off and covered her mouth. (TV: The Time of the Doctor [+]Loading...["The Time of the Doctor (TV story)"]) The Twelfth Doctor admitted that he had thought of himself in some sense as Clara's boyfriend while in his eleventh incarnation. (TV: Deep Breath [+]Loading...["Deep Breath (TV story)"])

In Amy Pond and Rory Williams, the Eleventh Doctor had a married couple aboard the TARDIS. (TV: A Christmas Carol [+]Loading...["A Christmas Carol (TV story)"], et al.) Rory sometimes had doubts as to whether Amy preferred the Doctor over him, leading to some tension. (TV: Day of the Moon [+]Loading...["Day of the Moon (TV story)"]) When Jo Jones found out about Amy and Rory, she felt embarrassed for having left the Third Doctor in order to get married to her husband Cliff Jones. (TV: Death of the Doctor [+]Loading...["Death of the Doctor (TV story)"])

Non-humans[[edit] | [edit source]]

The Doctor's Whifferdill companion, Frobisher, could morph into any form, but typically preferred to be a penguin. (COMIC: Where Nobody Knows Your Name [+]Loading...["Where Nobody Knows Your Name (comic story)"])

Despite a statistical preference for humans, the Doctor had non-human companions or at the very least, companions who were not from Earth or descended from its people. This included the First Doctor's earliest companion, Badger, an Avatroid that helped raise him as a childe in the House of Lungbarrow.

The non-human companions the Doctor travelled with usually had the outward appearance of a human or Time Lord. On at least three occasions they travelled with members of their own species. The longest serving were his granddaughter Susan Foreman, (TV: An Unearthly Child [+]Loading...["An Unearthly Child (TV story)"], et al.) Romana, (TV: The Ribos Operation [+]Loading...["The Ribos Operation (TV story)"], et al.) and John and Gillian Who. (COMIC: The Klepton Parasites [+]Loading...["The Klepton Parasites (comic story)"]) Lady Serena was significant as well, for sacrificing her life in service to the Doctor's goals. (PROSE: World Game [+]Loading...["World Game (novel)"]) Other human-like individuals with whom they adventured included, but certainly weren't limited to: Trakenite Nyssa, (TV: Logopolis [+]Loading...["Logopolis (TV story)"]) Alzarian Adric, (TV: Full Circle [+]Loading...["Full Circle (TV story)"]) Trion Vislor Turlough (TV: Mawdryn Undead [+]Loading...["Mawdryn Undead (TV story)"]) and Astrid Peth from Sto. (TV: Voyage of the Damned [+]Loading...["Voyage of the Damned (TV story)"])

On occasion, they were accompanied by obviously non-human species, like Whifferdills, (COMIC: The Shape Shifter [+]Loading...["The Shape Shifter (comic story)"]) Ice Warriors, (COMIC: Descendance [+]Loading...["Descendance (comic story)"]) Oblivioners, (COMIC: Bad Blood [+]Loading...["Bad Blood (comic story)"]) Eutermesans, (AUDIO: The Creed of the Kromon [+]Loading...["The Creed of the Kromon (audio story)"]) Vessicans (COMIC: Thinktwice [+]Loading...["Thinktwice (comic story)"]) and cyber-converted humans. (COMIC: The Company of Thieves [+]Loading...["The Company of Thieves (comic story)"]) During her time working for the Division, the Fugitive Doctor had a Lupar companion named Karvanista. (TV: Once, Upon Time [+]Loading...["Once, Upon Time (TV story)"], The Vanquishers [+]Loading...["The Vanquishers (TV story)"]) The Fourteenth Doctor briefly formed a companionship with a pig, whom he named Alfredo. (PROSE: Under Control [+]Loading...["Under Control (short story)"])

Artificial life-forms sometimes travelled with the Doctor, as well. Clearly, K9 was the Doctor's most-beloved robotic companion, given the number of models the Doctor built (TV: The Invasion of Time [+]Loading...["The Invasion of Time (TV story)"], School Reunion [+]Loading...["School Reunion (TV story)"], A Girl's Best Friend [+]Loading...["A Girl's Best Friend (TV story)"]) and the pleasure the Tenth Doctor displayed when he re-encountered a version of the robot. (TV: School Reunion [+]Loading...["School Reunion (TV story)"], The Wedding of Sarah Jane Smith [+]Loading...["The Wedding of Sarah Jane Smith (TV story)"]) The Doctor seemed empathetic to artificial life-forms with errors in their programming. The Fifth Doctor once effectively euthanised an android companion in irremediable distress. (TV: Planet of Fire [+]Loading...["Planet of Fire (TV story)"])

Shortly before his time on Trenzalore, the Eleventh Doctor obtained a Cyberman head he named "Handles". Handles aided him greatly with technological assistance, being his only real companion during his first three hundred years on Trenzalore as he'd sent Clara Oswald home and everyone he cared about that lived there eventually died. After three hundred years, Handles died of old age, reducing the Doctor to tears. (TV: The Time of the Doctor [+]Loading...["The Time of the Doctor (TV story)"])

The Twelfth Doctor teamed up with a Dalek named Lumpy to collect the Orb of Fates and stop the Daleks, Cybermen and Sontarans from controlling the Starbane. However, it turned out that Lumpy had tricked the Doctor at the very beginning of the adventure. (GAME: The Doctor and the Dalek [+]Loading...["The Doctor and the Dalek (video game)"]) His later companion, Nardole, was humanoid, but explicitly not human - he was at least partially cybernetic, (TV: The Pilot [+]Loading...["The Pilot (TV story)"]) harboured a distaste for humans, (TV: Smile [+]Loading...["Smile (TV story)"], The Doctor Falls [+]Loading...["The Doctor Falls (TV story)"]) and was only "human enough" because the Doctor had gotten his lungs cheap. (TV: The Pyramid at the End of the World [+]Loading...["The Pyramid at the End of the World (TV story)"])

Comings and goings[[edit] | [edit source]]

Joining the Doctor[[edit] | [edit source]]

Zoe is discovered attempting to stow away in the console room. (TV: The Wheel in Space [+]Loading...["The Wheel in Space (TV story)"])

The Doctor began relationships with their companions in a great variety of ways. Some, like Adric, (TV: State of Decay [+]Loading...["State of Decay (TV story)"]) Leela, (TV: The Face of Evil [+]Loading...["The Face of Evil (TV story)"]) Tara, (COMIC: Official Secrets [+]Loading...["Official Secrets (comic story)"]) and Zoe, (TV: The Wheel in Space [+]Loading...["The Wheel in Space (TV story)"]) stowed away on the TARDIS, fully aware it was a ship that could take them away from their home. Others, like Ian Chesterton, Barbara Wright (TV: "An Unearthly Child" [+]Part of An Unearthly Child, Loading...{"namedep":"An Unearthly Child (1)","1":"An Unearthly Child (TV story)"}) and Dodo Chaplet, (TV: "Bell of Doom" [+]Part of The Massacre, Loading...{"namedep":"Bell of Doom (4)","1":"The Massacre (TV story)"}) were taken away without their consent. They were also occasionally assigned assistants by those in nominal authority over him. During his exile on Earth, the Third Doctor's assistants were mostly supplied by the Brigadier. (TV: Spearhead from Space [+]Loading...["Spearhead from Space (TV story)"], Terror of the Autons [+]Loading...["Terror of the Autons (TV story)"]) In the case of UNIT soldiers, the Doctor worked with whomever the Brigadier happened to have on duty at the time of a crisis. This was how he first met Mike Yates. (PROSE: The Eye of the Giant [+]Loading...["The Eye of the Giant (novel)"]) The Doctor's other "bosses" — the Time Lords (PROSE: World Game [+]Loading...["World Game (novel)"], AUDIO: Blood of the Daleks [+]Loading...["Blood of the Daleks (audio story)"]) and the White Guardian (TV: The Ribos Operation [+]Loading...["The Ribos Operation (TV story)"]) — also occasionally provided companions, invariably against the Doctor's wishes. Even the Daleks understood that he was commonly assisted by companions. For example, when the Daleks abducted the Eleventh Doctor for a mission regarding the Dalek Asylum, they also abducted his most recent companions, Amy Pond and Rory Williams, to assist him. (TV: Asylum of the Daleks [+]Loading...["Asylum of the Daleks (TV story)"]) Much like the UNIT soldiers that worked with the Doctor as assistants under her father, Kate Stewart tended to help the Doctor on Earth when the situation brought them together. (TV: The Power of Three [+]Loading...["The Power of Three (TV story)"], The Day of the Doctor [+]Loading...["The Day of the Doctor (TV story)"], The Magician's Apprentice [+]Loading...["The Magician's Apprentice (TV story)"], The Zygon Invasion [+]Loading...["The Zygon Invasion (TV story)"] / The Zygon Inversion [+]Loading...["The Zygon Inversion (TV story)"], The Vanquishers [+]Loading...["The Vanquishers (TV story)"]) However, while helping to stop The Master's Dalek Plan, Kate briefly travelled in and even piloted the TARDIS, although it was made clear that this was the first time that she had ever stepped foot inside. Kate's constant help of the Doctor and her brief travel in the TARDIS appeared to grant her the status of companion as she was later invited by Graham O'Brien to a support group meeting of the Doctor's former companions. (TV: The Power of the Doctor [+]Loading...["The Power of the Doctor (TV story)"])

All that said, the most common way of initiating TARDIS travel was to be invited by the Doctor. Although with some cases there was, from their perspective, a significant gap of time between first meeting of the Doctor and getting to travel with him, Donna Noble, (TV: The Runaway Bride [+]Loading...["The Runaway Bride (TV story)"], Partners in Crime [+]Loading...["Partners in Crime (TV story)"]) Amy Pond (TV: The Eleventh Hour [+]Loading...["The Eleventh Hour (TV story)"]) and Rory Williams (TV: The Eleventh Hour [+]Loading...["The Eleventh Hour (TV story)"], The Vampires of Venice [+]Loading...["The Vampires of Venice (TV story)"]) were companions who began travelling at the Doctor's request a significant amount of time after they first met. In most cases there was little to no time gap between meeting the Doctor and getting to travel with them, Clara Oswald, (TV: The Bells of Saint John [+]Loading...["The Bells of Saint John (TV story)"]) Martha Jones, (TV: Smith and Jones [+]Loading...["Smith and Jones (TV story)"]) Rose Tyler, (TV: Rose [+]Loading...["Rose (TV story)"]) Jack Harkness, (TV: The Doctor Dances [+]Loading...["The Doctor Dances (TV story)"]) Ace, (TV: Dragonfire [+]Loading...["Dragonfire (TV story)"]) Vislor Turlough, (TV: Mawdryn Undead [+]Loading...["Mawdryn Undead (TV story)"]) Izzy Sinclair, (COMIC: Endgame [+]Loading...["Endgame (DWM comic story)"]) Charley Pollard, (AUDIO: Storm Warning [+]Loading...["Storm Warning (audio story)"]) Arnold, (COMIC: Children of the Evil Eye [+]Loading...["Children of the Evil Eye (comic story)"]) Jamie McCrimmon, (TV: The Highlanders [+]Loading...["The Highlanders (TV story)"]) Victoria Waterfield, (TV: The Evil of the Daleks [+]Loading...["The Evil of the Daleks (TV story)"]) Vicki (TV: "Desperate Measures" [+]Part of The Rescue, Loading...{"namedep":"Desperate Measures (2)","1":"The Rescue (TV story)"}) and others all began their travels with the Doctor because he asked them. Mickey Smith became a companion by asking the Doctor if he could travel with him, rather than the other way around. (TV: School Reunion [+]Loading...["School Reunion (TV story)"])

Other companions "forced" their way into the TARDIS. Leela, despite the Fourth Doctor's protests, ran into the TARDIS and, before he could shoo her out, fiddled with the controls, causing it to dematerialise. (TV: The Face of Evil [+]Loading...["The Face of Evil (TV story)"])

Rarely, the Doctor invited people to travel with them, like Lynda Moss, (TV: The Parting of the Ways [+]Loading...["The Parting of the Ways (TV story)"]) Astrid Peth (TV: Voyage of the Damned [+]Loading...["Voyage of the Damned (TV story)"]) and Rita, (TV: The God Complex [+]Loading...["The God Complex (TV story)"]) only to have their death prevent their travels. The same thing happened with Clara Oswin Oswald, although the Doctor found out that there was another version of her somewhere in time and space and set out to find her. (TV: The Snowmen [+]Loading...["The Snowmen (TV story)"])

Leaving the Doctor[[edit] | [edit source]]

People left the Doctor for reasons as varied as the reasons they first walked through the TARDIS doors. They were of three broad types: the companion wanted to leave; (TV: "The Planet of Decision" [+]Part of The Chase, Loading...{"namedep":"The Planet of Decision (6)","1":"The Chase (TV story)"}, "Horse of Destruction" [+]Part of The Myth Makers, Loading...{"namedep":"Horse of Destruction (4)","1":"The Myth Makers (TV story)"}, The Savages [+]Loading...["The Savages (TV story)"], The War Machines [+]Loading...["The War Machines (TV story)"], Last of the Time Lords [+]Loading...["Last of the Time Lords (TV story)"]) the Doctor wanted the companion to leave; (TV: "Flashpoint" [+]Part of The Dalek Invasion of Earth, Loading...{"namedep":"Flashpoint (6)","1":"The Dalek Invasion of Earth (TV story)"}, The Long Game [+]Loading...["The Long Game (TV story)"], Utopia [+]Loading...["Utopia (TV story)"], The God Complex [+]Loading...["The God Complex (TV story)"]) or some external force compelled the companion and Doctor to separate. (TV: "The Traitors" [+]Part of The Daleks' Master Plan, Loading...{"namedep":"The Traitors (4)","1":"The Daleks' Master Plan (TV story)"}, "Destruction of Time" [+]Part of The Daleks' Master Plan, Loading...{"namedep":"Destruction of Time (12)","1":"The Daleks' Master Plan (TV story)"}, The War Games [+]Loading...["The War Games (TV story)"], The Hand of Fear [+]Loading...["The Hand of Fear (TV story)"], Earthshock [+]Loading...["Earthshock (TV story)"], Doomsday [+]Loading...["Doomsday (TV story)"], The Angels Take Manhattan [+]Loading...["The Angels Take Manhattan (TV story)"], Hell Bent [+]Loading...["Hell Bent (TV story)"])

When asked by Brian Williams, father to one of their companions, Rory Williams, and father-in-law to Amy Pond, another companion, what happened to the people who travelled with them, the Eleventh Doctor explained that some left him, some got left behind, and also admitted that "not many, but some" died. (TV: The Power of Three [+]Loading...["The Power of Three (TV story)"]) The Sixth Doctor confided in Jack Harkness, who was abandoned by the Ninth Doctor, that he did it to "the best of [their] companions and the robot dog." (AUDIO: Piece of Mind [+]Loading...["Piece of Mind (audio story)"])

The companion's choice[[edit] | [edit source]]

The choice to leave was sometimes the companion's.

A common reason for the departure of female human companions was romance. Sometimes, as with Vicki, (TV: "Horse of Destruction" [+]Part of The Myth Makers, Loading...{"namedep":"Horse of Destruction (4)","1":"The Myth Makers (TV story)"}) Jo (TV: The Green Death [+]Loading...["The Green Death (TV story)"]) and Leela, (TV: The Invasion of Time [+]Loading...["The Invasion of Time (TV story)"]) they left to get married, while at least one companion, Martha Jones, left partly because she realised her romantic feelings for the Tenth Doctor would never be reciprocated. (TV: Last of the Time Lords [+]Loading...["Last of the Time Lords (TV story)"]) On other occasions, the Doctor travelled with married couples in the TARDIS, most notably Amy Pond and Rory Williams. (TV: The Big Bang [+]Loading...["The Big Bang (TV story)"], et al.)

Ian and Barbara back home in London after their travels with the First Doctor. (TV: "The Planet of Decision" [+]Part of The Chase, Loading...{"namedep":"The Planet of Decision (6)","1":"The Chase (TV story)"})

In the Doctor's youth, before they had established reasonable control over the TARDIS, companions sometimes left, at least in part, because they happened to have access to their own time period and wanted to return home. This was especially true of the companions who had not actually chosen to travel with the Doctor, such as Ian and Barbara, (TV: "The Planet of Decision" [+]Part of The Chase, Loading...{"namedep":"The Planet of Decision (6)","1":"The Chase (TV story)"}) Dodo, (TV: The War Machines [+]Loading...["The War Machines (TV story)"]) and Polly and Ben. (TV: The Faceless Ones [+]Loading...["The Faceless Ones (TV story)"]) However, this sometimes happened later in the Doctor's life. Ly-Chee, for instance, thought the Seventh Doctor was only offering him a lift into town. Instead, they had several adventures together. When the TARDIS finally deposited him in the correct town, he headed for the nearest pub and ordered a stiff drink without once looking back. (COMIC: The Enlightenment of Ly-Chee the Wise [+]Loading...["The Enlightenment of Ly-Chee the Wise (comic story)"])

Some companions left to improve a particular society they had encountered with the Doctor. Nyssa left to help cure Lazar's disease, (TV: Terminus [+]Loading...["Terminus (TV story)"]) whilst Steven Taylor stayed on the planet of the Elders to be its leader. (TV: The Savages [+]Loading...["The Savages (TV story)"]) Likewise, Romana II chose to remain in E-Space to help the Tharil species. (TV: Warriors' Gate [+]Loading...["Warriors' Gate (TV story)"]) Tara Mishra left the Ninth Doctor after wishing to stay and help with the disaster aftermath on Nomicae, (COMIC: The Bidding War [+]Loading...["The Bidding War (comic story)"]) though both parties made it explicit that this was temporary, and Jack Harkness was sent to collect her after some time. (COMIC: The Lost Dimension [+]Loading...["The Lost Dimension (comic story)"]) Later, Mickey Smith deliberately stayed in the parallel Pete's World to help its citizens defeat the Cybermen and to support his grandmother's living parallel counterpart. (TV: The Age of Steel [+]Loading...["The Age of Steel (TV story)"]) Mickey proved especially independent when it came to departing the Doctor's side; he later left the TARDIS again, this time to return to his "home" Earth, ultimately to defend it from alien threats. (TV: Journey's End [+]Loading...["Journey's End (TV story)"], The End of Time [+]Loading...["The End of Time (TV story)"])

Others left for more personal improvement. Melanie Bush parted ways from the Seventh Doctor purely to have new adventures in space — but not time — with Sabalom Glitz. (TV: Dragonfire [+]Loading...["Dragonfire (TV story)"]) Frobisher left the Doctor to enjoy the pleasure planet A-Lux. (COMIC: A Cold Day in Hell! [+]Loading...["A Cold Day in Hell! (comic story)"]) Liz Shaw left UNIT and the Third Doctor to return to her research, telling the Brigadier that all the Doctor needed in an assistant was "someone to pass him his test tubes and tell him how brilliant he was". (TV: Terror of the Autons [+]Loading...["Terror of the Autons (TV story)"]) After another brief adventure on Messaline Martha Jones declined to travel with the Doctor again wishing to be a part of UNIT. (TV: The Doctor's Daughter [+]Loading...["The Doctor's Daughter (TV story)"])

Some companions left simply because they no longer enjoyed travelling with the Doctor. Victoria Waterfield left because she had grown tired of the continual danger in which she found herself and decided to choose a safer new life. (TV: Fury from the Deep [+]Loading...["Fury from the Deep (TV story)"]) Tegan Jovanka similarly left because she had become sickened by the death and destruction she witnessed. (TV: Resurrection of the Daleks [+]Loading...["Resurrection of the Daleks (TV story)"]) Likewise, Dan Lewis made the choice to leave following a near-death experience. (TV: The Power of the Doctor [+]Loading...["The Power of the Doctor (TV story)"])

Because they were Earth-based assistants who either never wanted to travel with the Doctor on a long-term basis or never were invited to do so, a few companions made only a single journey or two, but otherwise provided significant assistance from Earth. The Brigadier (TV: The Invasion [+]Loading...["The Invasion (TV story)"], The Five Doctors [+]Loading...["The Five Doctors (TV story)"]) and Wilfred Mott (TV: The Stolen Earth [+]Loading...["The Stolen Earth (TV story)"], The End of Time [+]Loading...["The End of Time (TV story)"]) were classic examples of this sort of assistant, but Maxwell Edison (COMIC: Stars Fell on Stockbridge [+]Loading...["Stars Fell on Stockbridge (comic story)"]) and, for a time, Mickey Smith (TV: Aliens of London [+]Loading...["Aliens of London (TV story)"] / World War Three [+]Loading...["World War Three (TV story)"], School Reunion [+]Loading...["School Reunion (TV story)"], The Girl in the Fireplace [+]Loading...["The Girl in the Fireplace (TV story)"]) could be viewed in this light as well. Harry Sullivan also left the Doctor to return to his usual life after a single trip in the TARDIS, (TV: Terror of the Zygons [+]Loading...["Terror of the Zygons (TV story)"]) albeit one punctuated by several detours by other means.

One companion who briefly left by her choice was Clara Oswald. After a trip to the Moon in which she was forced to decide whether to kill an innocent creature or to save planet Earth, the Twelfth Doctor refused to help, Clara grew so angry she left the TARDIS, telling the Doctor never to come and find her again. (TV: Kill the Moon [+]Loading...["Kill the Moon (TV story)"]) However, with the help of Danny Pink, she realised she wasn't ready to give up the Doctor yet and agreed to a final trip with him weeks later to the Orient Express at which point she decided to permanently rejoin him despite the dangers and the coldness the Doctor once again displayed on the trip. (TV: Mummy on the Orient Express [+]Loading...["Mummy on the Orient Express (TV story)"]) Clara again left the TARDIS after Danny's death, under the mistaken belief that the Doctor had found his home planet of Gallifrey, while the Doctor believed that Danny was alive and with Clara. (TV: Death in Heaven [+]Loading...["Death in Heaven (TV story)"]) Later, the Doctor returned to save her life, in an adventure in which both lies were exposed. Afterwards, the Doctor gave Clara one more invitation to join him again, and she accepted. (TV: Last Christmas [+]Loading...["Last Christmas (TV story)"])

The Doctor's choice[[edit] | [edit source]]
The Third Doctor returns Arnold to his home before he's "alienated" from his own time. (COMIC: The Amateur [+]Loading...["The Amateur (comic story)"])

Sometimes companions were kicked out of the TARDIS, either as punishment or for the companion's personal growth. Adam Mitchell was summarily tossed out after he was found trying to use his trip into the future to alter his own fortunes. (TV: The Long Game [+]Loading...["The Long Game (TV story)"])

Susan, (TV: "Flashpoint" [+]Part of The Dalek Invasion of Earth, Loading...{"namedep":"Flashpoint (6)","1":"The Dalek Invasion of Earth (TV story)"}) Arnold, (COMIC: The Amateur [+]Loading...["The Amateur (comic story)"]) John and Gillian (COMIC: Invasion of the Quarks [+]Loading...["Invasion of the Quarks (comic story)"]) were more charitably dismissed. The Doctor clearly believed he was doing them good by ending their travels. The Doctor prevented these youths from continuing to travel with them because he felt it would interfere with their natural maturation. Married couple Amy and Rory were returned home by the Eleventh Doctor, who feared for their lives if they continued on their travels. (TV: The God Complex [+]Loading...["The God Complex (TV story)"]) The Twelfth Doctor left Clara Oswald home after believing she'd gotten her dead boyfriend Danny Pink back from the Nethersphere and would be happy with him. (TV: Death in Heaven [+]Loading...["Death in Heaven (TV story)"]) As the Thirteenth Doctor prepared to regenerate, she returned Yasmin Khan home, deciding to face her next incarnation alone. (TV: The Power of the Doctor [+]Loading...["The Power of the Doctor (TV story)"])

Separation by situation[[edit] | [edit source]]
Rose is separated from the Tenth Doctor after the "void stuff" pulled her to Pete's World. (TV: Doomsday [+]Loading...["Doomsday (TV story)"])

There were occasions when the Doctor and their companions were separated more by circumstance than the wishes of either party. Perhaps the most obvious case of this was when the Tenth Doctor and Rose Tyler were separated by the closure of the walls between dimensions. (TV: Doomsday [+]Loading...["Doomsday (TV story)"]) Sarah Jane Smith's departure occurred because the Fourth Doctor was summoned to Gallifrey (TV: The Hand of Fear [+]Loading...["The Hand of Fear (TV story)"]) at a moment in Gallifreyan history when humans weren't allowed on the planet. (TV: School Reunion [+]Loading...["School Reunion (TV story)"]) The Time Lords forced Zoe and Jamie to part from the Second Doctor, with only the memories of their first adventure with him intact. (TV: The War Games [+]Loading...["The War Games (TV story)"]) The Time Lords later claimed they had developed this procedure into a "standard response" for companions with whom they dealt. The Sixth Doctor, for instance, encountered a version of Peri Brown who had been given "the Jamie and Zoe treatment". She retained memories only of the adventure with the Fifth Doctor, Turlough and the Tremas Master which began on Lanzarote. (AUDIO: Peri and the Piscon Paradox [+]Loading...["Peri and the Piscon Paradox (audio story)"]) Finally, whilst in his tenth body, the Doctor had to stabilise the effects of a biologically untenable combination of his DNA with Donna Noble's. To do so, he had to submerge all memories of her time with him and shield her from those memories lest she die. Thus, although he did, in a sense, kick her out of the TARDIS for her own good, neither wanted it. (TV: Journey's End [+]Loading...["Journey's End (TV story)"]) She did briefly remember snippets of her travels but was knocked unconscious by it and then forgot again. (TV: The End of Time [+]Loading...["The End of Time (TV story)"]) Similarly, Donna's consciousness was saved to The Library against her will, causing her to forget about the Doctor and spending years from her point of view married to Lee McAvoy. This was only temporary, however, and soon afterwards she resumed her travels. (TV: Silence in the Library [+]Loading...["Silence in the Library (TV story)"] / Forest of the Dead [+]Loading...["Forest of the Dead (TV story)"])

Jack Harkness' days in the TARDIS came to an end in similarly unusual circumstances. Because he had died and been resurrected by Rose as the Bad Wolf entity, he became, in the words of the Tenth Doctor "just wrong". No longer able to die, he was instead a kind of "fixed point in time" which the TARDIS herself rejected. (TV: Utopia [+]Loading...["Utopia (TV story)"]) Nevertheless, the Doctor re-invited him on board the TARDIS (TV: Last of the Time Lords [+]Loading...["Last of the Time Lords (TV story)"]) and he later travelled aboard it without apparent difficulty. (TV: Journey's End [+]Loading...["Journey's End (TV story)"]) However, on both occasions, he was more interested in pursuing a life with Torchwood Three than returning to the Doctor's side on a long-term basis.

Amy Pond and Rory Williams were sent back in time by a Weeping Angel, separating them from the Eleventh Doctor for the remainder of their lives. They died at age 87 and 82 respectively. (TV: The Angels Take Manhattan [+]Loading...["The Angels Take Manhattan (TV story)"])

Death[[edit] | [edit source]]

Some companions died, often in service to the Doctor's goals. Katarina (TV: "The Traitors" [+]Part of The Daleks' Master Plan, Loading...{"namedep":"The Traitors (4)","1":"The Daleks' Master Plan (TV story)"}) and Sara Kingdom (TV: "Destruction of Time" [+]Part of The Daleks' Master Plan, Loading...{"namedep":"Destruction of Time (12)","1":"The Daleks' Master Plan (TV story)"}) both died to prevent the Daleks obtaining taranium. Oliver Harper (AUDIO: The First Wave [+]Loading...["The First Wave (audio story)","The First Wave"]) was killed by the Vardans while protecting both Steven and the Doctor. Adric sacrificed himself trying to stop a prehistoric Cyberman invasion of Earth. (TV: Earthshock [+]Loading...["Earthshock (TV story)"]) Roz Forrester died in battle. (PROSE: So Vile a Sin [+]Loading...["So Vile a Sin (novel)"]) Lucie Miller and Tamsin Drew were both killed whilst defeating the Dalek Time Controller's invasion of Earth in the late 22nd century. (AUDIO: To the Death [+]Loading...["To the Death (audio story)"]) Astrid Peth died killing Max Capricorn. Her atoms were left to travel the universe. Without her sacrifice, the Tenth Doctor would not have regained control of the Titanic, nor prevented it from having a costly collision into Buckingham Palace. (TV: Voyage of the Damned [+]Loading...["Voyage of the Damned (TV story)"], Turn Left [+]Loading...["Turn Left (TV story)"])

Cinder, who was briefly a companion of the War Doctor, sacrificed her life to save the Doctor when the Time Lord Karlax tried to kill him under orders from Rassilon. It was for fear of this highly probable eventuality of a companion's death that the War Doctor was reluctant to let a companion join him during his years of fighting in the Last Great Time War. He gave Cinder a proper burial and promised to end the Time War to honour her sacrifice. (PROSE: Engines of War [+]Loading...["Engines of War (novel)"])

Three unusual cases were those of Peri Brown, Ace and River Song.

Peri was killed by King Yrcanos on Thoros Beta, whilst her body was being subjected to Crozier's troubling body-swapping experimentations. For a time, the Sixth Doctor believed Peri had died. At the conclusion of his second major trial by the Time Lords, however, the Inquisitor revealed Peri's death had likely been a trick of the Valeyard. The Inquisitor showed the Doctor that Peri, far from being killed by Yrcanos, had, in fact, married him. (TV: Mindwarp [+]Loading...["Mindwarp (TV story)"]) However, at a later date, the Time Lords revealed their meddling with Peri's timestreams had resulted in multiple versions of Peri running around the cosmos. One of these Peris had been killed by Yrcanos, as the Doctor originally believed. (AUDIO: Peri and the Piscon Paradox [+]Loading...["Peri and the Piscon Paradox (audio story)"])

Ace dies in the Seventh Doctor's arms. (COMIC: Ground Zero [+]Loading...["Ground Zero (comic story)"])

Like Peri, Ace died young according to two accounts, but not others. According to one, she died while using Nitro-9 against parasitic beings known as the Lobri. Her sacrifice saved the lives of Sarah Jane, Susan, Peri and the Seventh Doctor. (COMIC: Ground Zero [+]Loading...["Ground Zero (comic story)"]) In another account she was killed by George Limb, only to be replaced by a divergent version of herself, who continued to travel with the Doctor and who only had superficial differences from her other self. (PROSE: Loving the Alien [+]Loading...["Loving the Alien (novel)"]) Furthermore, according to other accounts, she lived to a much older age — at least into her late thirties and fifties. (PROSE: Set Piece [+]Loading...["Set Piece (novel)"], At Childhood's End [+]Loading...["At Childhood's End (novel)"], et al.)

River Song died physically when she linked her mind into the CAL computer during the Doctor's first meeting with her — from his perspective; from hers, it was the last of many following an unspecified period of time as his companion. (TV: Forest of the Dead [+]Loading...["Forest of the Dead (TV story)"]) Unknown to the Tenth Doctor, River was part Time Lord due to having been conceived on board the TARDIS by the Doctor's future companions Amy Pond and Rory Williams, but had given up her future regenerations to save the Eleventh Doctor's life. (TV: A Good Man Goes to War [+]Loading...["A Good Man Goes to War (TV story)"], Let's Kill Hitler [+]Loading...["Let's Kill Hitler (TV story)"]) The Doctor, therefore, proceeded with his timeline knowing how River would one day die. He gave her a sonic screwdriver specially designed to save her mental patterns at the moment of her death in the Library. (TV: The Husbands of River Song [+]Loading...["The Husbands of River Song (TV story)"]) This allowed the earlier Tenth Doctor to upload River into CAL's immense memory bank, allowing her to live on in the computer. (TV: Forest of the Dead [+]Loading...["Forest of the Dead (TV story)"]) She later managed to somehow link herself into a psychic "conference call" from inside CAL even as a data ghost to aid the Doctor one last time on Trenzalore before fading forever after he finally said goodbye to her. (TV: The Name of the Doctor [+]Loading...["The Name of the Doctor (TV story)"])

Kamelion, an android companion, was destroyed by the Fifth Doctor in an act of mercy per Kamelion's own request after he was taken over by the Tremas Master. (TV: Planet of Fire [+]Loading...["Planet of Fire (TV story)"])

Clara Oswald, a companion of the Eleventh and Twelfth Doctors, sacrificed herself for Rigsy, whom she had only met once before. She was killed by a Quantum Shade after saying goodbye to the Time Lord, with the Doctor ultimately blaming Ashildr for her death. (TV: Face the Raven [+]Loading...["Face the Raven (TV story)"]) The Twelfth Doctor extracted her from her timestream moments before her death using Time Lord technology, although she was frozen in between one heartbeat and her last. He realised that they couldn't continue travelling together as the prophecies of the Hybrid would come to pass, so he planned to erase Clara's memories of him with a neural block. However, upon discovering this, Clara attempted to reverse the polarity of the neural block so it would affect the Doctor, something he doubted had worked when she told him. They agreed to activate the device together, not knowing which one of them would be affected, and it affected the Doctor. Clara left in a stolen TARDIS with Ashildr to travel the universe before returning to Gallifrey and dying. (TV: Hell Bent [+]Loading...["Hell Bent (TV story)"]

Unknown reasons[[edit] | [edit source]]

Very rarely, it was unknown what caused certain companions to stop travelling with the Doctor.

In the case of the Earthbound Third Doctor, relationship timings with his occasional assistants became very unclear. Assistants in this period didn't stop travelling with him; his exile on Earth made it impossible for them to start travelling with him. (TV: Spearhead from Space [+]Loading...["Spearhead from Space (TV story)"] - The Three Doctors [+]Loading...["The Three Doctors (TV story)"]) Assistants during this period tended to be people who lived in England (TV: Spearhead from Space [+]Loading...["Spearhead from Space (TV story)"], Terror of the Autons [+]Loading...["Terror of the Autons (TV story)"]) whom he could meet in Bessie. Since he wasn't housing companions in the TARDIS, there wasn't a definite "moment" when an assistant entered or left "the TARDIS team". Therefore, incomplete records existed as to how long the Doctor knew certain assistants. It was never known, for example, definitively when the Doctor met or said goodbye to Tom Phipps and Joe. (COMIC: The Vortex [+]Loading...["The Vortex (comic story)"], Fogbound [+]Loading...["Fogbound (comic story)"]) Similarly, it was never known how the Fourth Doctor met or parted with Joan Brown (COMIC: Doomcloud [+]Loading...["Doomcloud (comic story)"]) or Young. (COMIC: The Sea Devil [+]Loading...["The Sea Devil (comic story)"])

A similar situation occurred when the Eleventh Doctor had to guard Trenzalore for hundreds of years. Individuals such as Theol Willoughby who acted as companions did not enter or leave the TARDIS team, not least because the TARDIS was travelling in the Time Vortex for a prolonged period of time without him. Due to the extended lifespan of the Doctor, he outlived the inhabitants of the town making it impossible to determine when exactly they became companions. (TV: The Time of the Doctor [+]Loading...["The Time of the Doctor (TV story)"], PROSE: An Apple a Day... [+]Loading...["An Apple a Day... (short story)"])

The influence of Gallifrey[[edit] | [edit source]]

The Fourth Doctor lost four consecutive companions to the direct or indirect influence of Gallifrey: he was forced to leave Sarah Jane Smith on Earth on receiving an emergency summons; (TV: The Hand of Fear [+]Loading...["The Hand of Fear (TV story)"]) Leela and K9 Mark I chose to stay on Gallifrey; (TV: The Invasion of Time [+]Loading...["The Invasion of Time (TV story)"]) and Romana II, who had been summoned to return to Gallifrey, (TV: Full Circle [+]Loading...["Full Circle (TV story)"]) escaped by remaining in E-Space with K9 Mark II. (TV: Warriors' Gate [+]Loading...["Warriors' Gate (TV story)"]) The Sixth Doctor was also unable to save Peri Brown, being transported away by the Time Lords at a crucial moment. (TV: Mindwarp [+]Loading...["Mindwarp (TV story)"])

The warden of the Twelfth Doctor's confession dial, the Veil, was actually a benevolent being, trying to help the Doctor escape during his imprisonment. It came to see itself as his companion, hoping the Doctor would take it with him to what laid beyond the dial. However, because he was unaware of the Veil's true nature, (PROSE: The Veil [+]Loading...["The Veil (short story)"]) the Doctor displayed no sadness when the being died. (TV: Heaven Sent [+]Loading...["Heaven Sent (TV story)"])

Balancing travels and home[[edit] | [edit source]]

We have two lives. Real life and Doctor life. Except real life doesn't get much of a look in.Rory Williams [The Power of Three (TV story) [src]]

After joining the Ninth Doctor on his travels, Rose Tyler made what was intended to be a quick stop home to see her mother, Jackie Tyler. However, they found that the TARDIS had taken them 12 months after Rose left, rather than the intended 12 hours. (TV: Aliens of London [+]Loading...["Aliens of London (TV story)"]) After being embroiled in the London UFO crash, Rose left with the Doctor again. Though she told Jackie that she could be back within 10 seconds, she did not return after that time elapsed. (TV: World War Three [+]Loading...["World War Three (TV story)"]) In fact, Rose would be away from home for extended periods of time as she continued travelling with the Doctor. (TV: Boom Town [+]Loading...["Boom Town (TV story)"], The Parting of the Ways [+]Loading...["The Parting of the Ways (TV story)"]) Following his regeneration, the Tenth Doctor returned to the Powell Estate with Rose on Christmas Eve. (TV: The Christmas Invasion [+]Loading...["The Christmas Invasion (TV story)"]) Following Christmas, Rose resumed her travels with the Doctor, being seen off by Jackie. (TV: New Earth [+]Loading...["New Earth (TV story)"]) Jackie told Elton Pope that Rose called her now and then but not as often as she liked, and admitted that she felt "left behind". (TV: Love & Monsters [+]Loading...["Love & Monsters (TV story)"])

Martha Jones, a medical student who joined the Doctor for "one trip" in the TARDIS, (TV: Smith and Jones [+]Loading...["Smith and Jones (TV story)"]) was eventually returned home 12 hours after she had left, only to rejoin the Doctor that same day after the pair confronted Richard Lazarus. (TV: The Lazarus Experiment [+]Loading...["The Lazarus Experiment (TV story)"]) Soon after, she made a phone call to her mother, Francine Jones, who told her that it was election day. (TV: 42 [+]Loading...["42 (TV story)"]) Upon returning home using Jack Harkness's vortex manipulator after the TARDIS was stolen by the Saxon Master, Martha found that it was the day after the election, only four days after she had met the Doctor. (TV: The Sound of Drums [+]Loading...["The Sound of Drums (TV story)"])

Romance[[edit] | [edit source]]

In one future stemming from the Eighth Doctor's life, (PROSE: The Tomorrow Windows [+]Loading...["The Tomorrow Windows (novel)"]) the Ninth Doctor was engaged to be married to Emma, the only travelling companion he had ever "had". However, an incident which caused the Doctor to undergo four regenerations in quick succession resulted in Emma calling off her marriage to the female Thirteenth Doctor. (TV: The Curse of Fatal Death [+]Loading...["The Curse of Fatal Death (TV story)"]) The Doctor had previously married Romana during his fourth incarnation after receiving advice from a Prime Computer. (TV: On Through the 80's! [+]Loading...["On Through the 80's! (TV story)"])

Understanding that Jack Harkness was "just a bit more flexible when it [came] to dancing", the Ninth Doctor posed the question of who he would like to "dance" with, himself or Rose Tyler. (TV: The Empty Child [+]Loading...["The Empty Child (TV story)"]) Before facing a Dalek attack on the Game Station, Jack gave the Doctor a goodbye kiss. (TV: The Parting of the Ways [+]Loading...["The Parting of the Ways (TV story)"]) Having been "abandoned" by the Doctor, (AUDIO: Piece of Mind [+]Loading...["Piece of Mind (audio story)"]) Jack was recorded as saying that, when he found the Doctor, he would kiss him before killing him. (TV: Fragments [+]Loading...["Fragments (TV story)"]) When he saw that Martha Jones "fancied" the Tenth Doctor, Jack asked "you too, huh?" (TV: The Sound of Drums [+]Loading...["The Sound of Drums (TV story)"]) Mistakenly believing Graham O'Brien to be a new incarnation of the Doctor, Jack described him as "still sexy". (TV: Fugitive of the Judoon [+]Loading...["Fugitive of the Judoon (TV story)"])

Martha Jones grew to fall in love with the Doctor as she travelled with him, (TV: The Sound of Drums [+]Loading...["The Sound of Drums (TV story)"]) and it was her knowledge that he would not reciprocate her feelings that led her to leave the TARDIS for home, as well as the impact the The Year That Never Was had on her family. (TV: Last of the Time Lords [+]Loading...["Last of the Time Lords (TV story)"])

Acknowledging that his time with Martha got "complicated", the Doctor told Donna Noble that he just wanted "a mate". Donna, who had misheard the Doctor as saying that he wanted "to mate", expressing her disgust and rejection of such a prospect. (TV: Partners in Crime [+]Loading...["Partners in Crime (TV story)"]) The Doctor and Donna were mistaken for a married couple on multiple instances, a misconception which they were quick to correct.

Companions of other Time Lords[[edit] | [edit source]]

The Master[[edit] | [edit source]]

Other Time Lords had companions in their travels. Before his final corruption into the renegade known as the Master, the Time Lord Koschei was accompanied in his hunt for the Doctor by Ailla. Koschei believed Ailla to be a young woman from a 28th century Earth colony, but she was, in fact, a Time Lady agent sent by the High Council to spy on his increasingly erratic behaviour. (PROSE: The Dark Path [+]Loading...["The Dark Path (novel)"])

The Tremas Master that joined with Tremas had control over Kamelion for a time. He used him to escape Xeriphas and to impersonate King John. However, the Doctor freed him from the Master's control and invited him to join the TARDIS crew, which he did. (TV: The King's Demons [+]Loading...["The King's Demons (TV story)"]) The Master later regained control over him, causing Kamelion to persuade the Doctor to destroy him. (TV: Planet of Fire [+]Loading...["Planet of Fire (TV story)"])

The Tremas Master also briefly bribed Sabalom Glitz to help him in his schemes and betray the Doctor although the Master was tricked by the Valeyard, ending his plan. (TV: The Ultimate Foe [+]Loading...["The Ultimate Foe (TV story)"]) According to one account, Christopher Marlowe's death was prevented by the Master who took him away from Deptford shortly before he was scheduled to die. He travelled with the Master for some time before returning and accepting his fate. (PROSE: Master Faustus [+]Loading...["Master Faustus (short story)"]) This Master also possessed an Auton duplicate that obeyed his commands. (GAME: Destiny of the Doctors [+]Loading...["Destiny of the Doctors (video game)"], HOMEVID: Destiny of the Doctors [+]Loading...["Destiny of the Doctors (home video)"])

In his battle with the newly regenerated Eighth Doctor, the Bruce Master was assisted by Chang Lee, a young man in 1999 San Francisco. Lee had been convinced by the Master that the Doctor was evil. Only too late did he learn the truth when the Master killed the boy, although the TARDIS subsequently restored him to life. (TV: Doctor Who [+]Loading...["Doctor Who (TV story)"])

During the Last Great Time War, the Master took on Cole Jarnish as a companion. (AUDIO: The Good Master [+]Loading...["The Good Master (audio story)"]) However, this was nothing more than a ruse and he killed him once his usefulness had come to an end. (AUDIO: The Heavenly Paradigm [+]Loading...["The Heavenly Paradigm (audio story)"]) As Professor Yana, the Master worked with Chantho, who in many ways could be considered his companion. However, after regaining memories of his previous incarnations, the Master killed Chantho. (TV: Utopia [+]Loading...["Utopia (TV story)"])

The Saxon Master took the Time Lord-companion relationship one step further by marrying his human companion Lucy Saxon, with every indication a passionate relationship existed between them, (TV: The Sound of Drums [+]Loading...["The Sound of Drums (TV story)"]) only for it to turn physically abusive, culminating in Lucy shooting and apparently killing her husband. (TV: Last of the Time Lords [+]Loading...["Last of the Time Lords (TV story)"], The End of Time [+]Loading...["The End of Time (TV story)"])

As part of a test of the Missy incarnation of the Master's redeemed goodness, the Twelfth Doctor sent her on a mission with his own companions Bill Potts and Nardole acting as Missy's companions. (TV: World Enough and Time [+]Loading...["World Enough and Time (TV story)"]) The Spy Master, while furthering the Kasaavin invasion, collaborated with Daniel Barton, who travelled with him in his TARDIS. (TV: Spyfall [+]Loading...["Spyfall (TV story)"])

Iris Wildthyme[[edit] | [edit source]]

The relationships between transtemporal adventuress, Iris Wildthyme, and her companions wasn't particularly complex (excluding the order of the companions; that was unambiguously contradictory). (PROSE: Wandering Stars [+]Loading...["Wandering Stars (short story)"], et al.)

Her companions varied significantly in appearance and personality, such as "butch dyke traffic warden" Jenny Winterleaf; (PROSE: Verdigris [+]Loading...["Verdigris (novel)"], Bafflement and Devotion [+]Loading...["Bafflement and Devotion (short story)"], et al.) erudite art critic Panda; (AUDIO: Wildthyme at Large [+]Loading...["Wildthyme at Large (audio story)"], PROSE: Wandering Stars [+]Loading...["Wandering Stars (short story)"], Death of the Author [+]Loading...["Death of the Author (short story)"], et al.) author Paul Magrs (PROSE: Bafflement and Devotion [+]Loading...["Bafflement and Devotion (short story)"], Party Fears Two [+]Loading...["Party Fears Two (short story)"], The Magrs Conundrum!

Others[[edit] | [edit source]]

When she left the Fourth Doctor in E-Space, Romana II was accompanied by K9 Mark II. (TV: Warriors' Gate [+]Loading...["Warriors' Gate (TV story)"]) K9 continued as her companion after she returned to Normal Space. (WC: Shada [+]Loading...["Shada (webcast)"], et al.) After returning to Gallifrey, Romana shared numerous adventures alongside one of the Doctor's former companions, Leela. (AUDIO: Gallifrey) In her fourth incarnation, Romana travelled with Ponch. (PROSE: Tomb of Valdemar [+]Loading...["Tomb of Valdemar (novel)"])

Renegade Time Lords in the part-time employ of the Celestial Intervention Agency often adopted Doctoresque lifestyles, complete with companions — only a few of whom had typically been assigned to them by the CIA as mission partners. Rollo's included fellow Time Lords Verika and Volusa, as well as a variety of humans from miscellaneous time-periods, such as Erin Grant, Jim Waters, Michael Duncan, David Smythe, Steven Reynart, Jody Lockhart, and, potentially, Julia Fraser and Thomas Carruthers. (GAME: The Iytean Menace [+]Loading...["The Iytean Menace (game)"])

Sometime after leaving the Doctor, Lucie Miller travelled with the Monk, apparently after responding to an advert that he placed in 2010 for a companion.

Behind the scenes[[edit] | [edit source]]

  • It is unknown what exactly caused the Eighth Doctor's companion Destrii's departure from the TARDIS. The start of the Ninth Doctor's era on television meant that the Eighth Doctor comics were coming to an end. With a reluctance to kill her off in her final appearance in the strip she simply stopped appearing. Destrii reappeared in The Stockbridge Showdown although her departure remained unaddressed.

What does the word "companion" actually mean?[[edit] | [edit source]]

Adam Mitchell kidnapped a number of the Doctor's companions (COMIC: The Choice)

The term "companion" is used more outside the programme — which is to say in fandom — than within the narrative. It was especially rarely used in the original version of the television programme. While the First Doctor referred to Ian Chesterton as "one of [his] companions" as early as The Daleks, it was practically never uttered by the Doctor himself until the John Nathan-Turner producership. "Assistant" was a far more common designation — being used, for instance, by the First Doctor to describe Dodo Chaplet in The War Machines, by the Brigadier to introduce Jo Grant in Terror of the Autons and by the Fifth Doctor to jog the Brig's memory of Jo in Mawdryn Undead. However, "companion" has been heard with greater regularity in other media — particularly that written since the transmission of Survival.

Indeed, Big Finish Productions have an entire range of product called The Companion Chronicles, which focuses on telling Doctor Who adventures from the perspective of the assistant. Equally, Doctor Who Magazine have taken to labelling the role that of "companion" — as they did on the cover of DWM 446, when they announced the arrival of Jenna-Louise Coleman. The tacit assumption between DWM editors and their readers is that, somehow, both groups know what the other is talking about — as if the word companion were a title whose qualifications and responsibilities were well defined. However, this is not the case.

Neither assistant nor companion have ever been unambiguously defined in a narrative. Without a solid in-universe definition, viewers are left to struggle with the term on their own. At what point, they are forced to ask themselves, does a supporting character become a "companion"? Is it when they travel in the TARDIS? If so, then Liz Shaw isn't a companion, despite being the clear co-star of an entire season. Is it when they're in more than one story? If so, then Sara Kingdom, Christina de Souza, Jackson Lake, Adelaide Brooke, Wilfred Mott and Astrid Peth must be struck from the list, despite the fact that their respective actors were given star billing in their respective episodes (Kingdom excluded as she was featured in a 1960s story, long before "star billing"). Can Jackie Tyler be considered a companion, since she appeared in numerous stories and she travelled in the TARDIS, and she even helped the Doctor recover after a regeneration?

Meta-fictional and story considerations are also a problem. Canton Everett Delaware III spent three months assisting the Doctor, travelled in the TARDIS at least once, and encountered him again forty years later, yet lack of star billing and the fact his time with the Doctor is shown over only two episodes puts his status in dispute.

Then there are behind-the-scenes concerns. If an actor like Jean Marsh tells us flatly that she was not hired as a companion (BFX: The Drowned World, DOC: From Kingdom to Queen) and the official BBC website's own list of companions does not include her, is it reasonable to consider Sara Kingdom a companion? If her, why not Bret Vyon, who also appeared in several episodes of TV: The Daleks' Master Plan fulfilling a function nearly identical to Sara? In a similar vein, the early story TV: The Keys of Marinus features two characters, Altos and Sabetha, who non-ambiguously joined the TARDIS crew as companions for the course of the single adventure, although they never rode in the TARDIS itself; do they have as valid a claim to being companions as Christina de Souza, who likewise never set foot in the TARDIS during her single adventure?

This question can be expanded to the literally hundreds of characters depicted on TV, in comic strips and in literature who over the years have filled companion-like roles in one-off stories as they encountered the Doctor. Indeed some of these characters have been promoted to ersatz companion status. For a time, Henry Gordon Jago and George Litefoot could be described as just this; one-off characters from TV: The Talons of Weng-Chiang who, decades later, were featured in an edition of the Big Finish Productions audio series, The Companion Chronicles, and later given their own spin-off series. However, they travelled with the Sixth Doctor in AUDIO: Voyage to Venus and Voyage to the New World, making their status as companions less controversial.

All these question marks! Determining who is a companion and who is not is one of the most common fan debates. It is possible by the fact that the television programme itself offers no definition for the term. Though probably exacerbated by the BBC Wales version's greater narrative flexibility, the debate is hardly a new one. It's been going on for ages, fuelled in previous decades by officially licensed reference works that helped mould fan opinion. For instance, the Brigadier, one of the people whose companion status is most hotly contested, gets some support for his alleged "companion status" from the book The Making of Doctor Who, in which two of the main writers of his era of the programme unambiguously called him a companion. Likewise, the later John Nathan-Turner book, The Companions was influential in making 1980s fans remember Sara Kingdom and for enshrining her as a companion — albeit against evidence in the BBC archives.

Still, though the new series put the term "companion" on more solid narrative ground, it greatly confuses the definition.

. . . what constitutes a Doctor Who companion is no longer clear. Sure, Rose, Martha and Donna were all companions. So was Captain Jack. But what about Mickey and Jackie? How do you qualify? Name in the opening credits, regular trips in the Tardis? The Doctor kisses you? I'm no longer sure. Modern TV drama is so difficult.Steven Brook, The Guardian[1]

In truth, though, it's never been very clear, even from a behind-the-scenes perspective. Though BBC Wales have confused things by putting single-episode guest stars in the opening credits, the "classic" series sowed similar confusion by often not listing "companions" very high in the credit list. Any definition of companion as "co-star" falls apart in the classic era, because companions were often listed after guest stars — sometimes after several guest stars. And claims that they were "regulars" must be counterbalanced against the fact that they were often contracted only for a matter of weeks, and lived under the threat of being unceremoniously dismissed mid-serial, like Jackie Lane was.

Term as used on this wiki[[edit] | [edit source]]

This narrative uncertainty makes it difficult for this wiki to consistently use the term. Several forum debates have raged as to how the term should be applied, including Disputed Companions and Who counts as a companion?. Those readers wishing to understand why certain companions are included on certain lists that appear on this site may want to explore those discussions; however, the simplest expression is that we will, by and large, err on the side of inclusivity, and entertain any plausible arguments that X character "counts".

Televised longevity[[edit] | [edit source]]

In televised Doctor Who, actors who played companions rarely stayed more than a series. Though some companions had notably long runs, they were the exception more than the rule.

Discounting companions like Astrid Peth and Sara Kingdom — each of whom appeared in only a single story — the record-holder for the shortest run would be Adam Mitchell. He appeared in only two stories or about 90 minutes of televised Doctor Who, spread across eight days of real-world time.

Yaz is the current record holder for longest continuous period of time on Doctor Who.

Record-holders for longest tenures can be measured in different ways.

  • In terms of individual episodes, Jamie McCrimmon is the easy winner with 113 episodes between The Highlanders and The War Games, outdistancing most Doctors, much less all other companions. He served for the better part of three seasons, during which Doctor Who had its highest episode count. Due to changed television consumption habits, that record will almost certainly never be approached, much less broken. (Note that the above number doesn't take into account episode 4 of The Enemy of the World where Jamie is still travelling with the Doctor but neither Frazer Hines nor Hamish Wilson appear on screen. Were that to be accounted for, Jamie would have two consecutive episode totals of 48 and 64, respectively. The total number increases to 116 if one includes his later return in The Two Doctors; Hines' appearance as Jamie in The Five Doctors is not included as he was only playing an apparition and not the actual character.)
  • In terms of stories, given that BBC Wales has a much higher story count (per season) compared to the original series, the high water mark has been set by Clara Oswald, appearing in 30 full-length televised stories from The Snowmen on 25 December 2012 to her exit in Hell Bent on 5 December 2015. Actor Jenna Coleman also appeared as an echo of Clara prior to The Snowmen in Asylum of the Daleks, and as part of the Testimony (Clara's memory) later on in Twice Upon a Time.
  • In terms of calendar time that the public would have perceived a character as being a regular on Doctor Who, the winner is Yasmin Khan, with a period of four years and 16 days from her first regular appearance in The Woman Who Fell to Earth on 7 October 2018 to her last regular appearance in The Power of the Doctor on 23 October 2022. Note that calendar years are not the same thing as seasons, as Doctor Who has not consistently begun its seasons on the same date or even month each year. Also, during Yasmin's tenure her three-series run aired in 2018, 2020, and 2021, with 2019 having a single New Year Special, Resolution, and her final three episodes in 2022 consisting of New Year Special Eve of the Daleks, Easter Special Legend of the Sea Devils, and BBC Centenary Special The Power of the Doctor.
  • In terms of the number of Doctors spanned, Donna Noble holds the record having been the regular companion of both the Tenth Doctor beginning on 5 April 2008 (after her first encounter with him in The Runaway Bride 2006 Christmas episode) and the Fourteenth Doctor ending on 9 December 2023, albeit with almost a decade and a half hiatus between each role.
  • In terms of length of incumbency, Ace is easily the record-holder, having joined the Doctor in 1987's Dragonfire and ceasing to be the incumbent companion by default nine years later when the 1996 TV Movie depicted the Seventh Doctor traveling alone.
  • In terms of season count, Tegan Jovanka and Sarah Jane Smith are, as of December 2022, the only travelling companions to appear during four consecutive seasons as a regular, having appeared in seasons 18 to 21 and seasons 11 to 14 respectively. Only Jo Grant, Sarah Jane, and Yaz appeared in three complete seasons, namely seasons 8 to 10; seasons 11 to 13; and series 11 to 13 of the BBC Wales/BBC Studios revival series.

Special mention should also be given here to the character of the Brigadier, who was an incredibly long-serving member of the cast. Regular or not, the character as played by Nicholas Courtney appeared in more episodes of the programme than all of the 1980s Doctors except Tom Baker, from The Web of Fear Episode 3 on 17 February 1968 to Battlefield Part Four on 27 September 1989, 21 years and 7 months later.
