More ambiguous

After stealing the Trakenite body of Tremas to replace his decaying Time Lord one, the Master resumed his crusade to conquer the universe and kill the Doctor. He somewhat succeeded in the latter, as his actions at the Pharos Project resulted in the regeneration of the Fourth Doctor, and he continued to plague the Doctor afterwards.

Eventually landing on the Cheetah World, the Master became infected with the Cheetah virus, which increased his aggressive behaviour. The Master would continue to be plagued by the virus for some time until he overcame the effects, but was then regressed back to his cadaverous form by the Warp Core. Disfigured, the Master was granted ten years of peaceful living on Earth as an amnesiac as part of a deal between the Seventh Doctor and Death. But, after his allotted time was up, he was restored to being the Master again.

Another account claimed that, immediately following his escape from the Cheetah World, he was cured by Tzun nanites and regenerated after being shot by Ace.

Biography

A new body

The Master after stealing Tremas' body. (TV: The Keeper of Traken)

A new body at last.The "Tremas" Master's first words

After an incident that resulted in his body being badly damaged, (PROSE: Legacy of the Daleks; AUDIO: The Two Masters) the Thirteenth Master, unable to regenerate due to being on his final regeneration, tried to find a way to heal his body. (TV: The Deadly Assassin) Eventually ending up at the Traken Union, the Master tried to become the Keeper of Traken to use the Source to heal himself, but his plan was foiled by the Fourth Doctor, Adric, Nyssa and Tremas. However, still possessing some lingering power of the Source, the Master was able to merge with Tremas, (TV: The Keeper of Traken) regenerating himself into a new body. (AUDIO: The Light at the End)

First exploits

{{Section stub|Information from ''[[The Unwanted Gift of Prophecy (short story)|The Unwanted Gift of Prophecy]]'', & ''[[Toy (short story)|Toy]]'' needs to be added}}

After he visited the Scoundrels Club to recover from changing bodies in comfort, (PROSE: Dismemberment) the Master went to Earth, where he trapped the Doctor's TARDIS in a gravity bubble. He killed Tegan Jovanka's aunt Vanessa and a police constable with his Tissue Compression Eliminator. He then went to Logopolis, where he pretended to be Tremas to gain Nyssa's cooperation, giving her a bracelet that allowed him to control her arm. Using her as a hostage, he perverted the Block Transfer Computations and held the planet for ransom until its secret was revealed. This made the causal nexus unravel and also broke the Logopolitans' blockade of entropy, allowing it to swallow several galaxies, including the entire Traken Union.

The entropy wave was so threatening that the Master agreed to work with the Fourth Doctor to stop it. They travelled to the Pharos Project on Earth to do so, using the last theorem of Logopolis to reopen Charged Vacuum Emboitments. However, his true plan was revealed when he sent a message to the peoples of the universe that he would stop the entropy only if they submitted to his rule. While the Doctor stopped the Master's signal to shut down the CVE that would halt the entropy wave, the Master caused him to fall off the Pharos Project's radio telescope and regenerate, allowing the Master to escape. (TV: Logopolis)

The Master travelled to Djinn to acquire some new masks from Moses, only to learn that he was dying, but that he could be saved with some Carenophil. However, after the Master retrieved some Carenophil from Restovan, Moses revealed that he had lied, and had sent the Master off on his pursuit to both keep him occupied long enough to lose the time needed to save him by unconventional means and to allow him a quick death by means of ingesting the poisonous Carenophil. Both outraged and impressed that he had been tricked, the Master moved Moses' masks into his TARDIS and left his body entombed in the castle fortress on Djinn. (PROSE: A Master of Disguise)

"The Portreeve" and the Fifth Doctor. (TV: Castrovalva)

As the Fifth Doctor made his leave in the TARDIS from the Pharos Project's radio telescope, the Master reappeared and kidnapped Adric and held him in a hadron web to make him a part of his TARDIS. Using a projection of Adric, the Master sent the Doctor's TARDIS hurtling to destruction at Event One, but the Doctor saved his TARDIS through the Architectural Configuration. The Master used Adric's block transfer computations to create Castrovalva in the Andromeda Galaxy, where the Doctor would recover from his regeneration. He escaped from the recursion trap and tried to kill the Doctor, but was attacked by the enraged citizens, with the city itself due to collapse. (TV: Castrovalva)

The Master remained trapped in Castrovalva for some time, but was able to find a way to project himself in England in the 1920s. In an attempt to capture and kill the Doctor and his companions and escape Castrovalva, the Master manipulated Harry Houdini to send a psionic distress call to his old friend. When the Doctor answered the call, Houdini claimed that he needed help to stop a fortune teller. However, when the Master's plan was uncovered, the Doctor managed to stop his revenge plan. (AUDIO: Smoke and Mirrors)

The Master as Kalid. (TV: Time-Flight)

The Master eventually escaped from Castrovalva, (TV: Time-Flight) but in the attempt, it caused damage to the dynamorphic generators, making it difficult to continue piloting his TARDIS. (PROSE: The Quantum Archangel) He managed to travel to Earth in 140,000,000 BC, where he disguised himself as the magician Kalid, hoping to use the Xeraphin gestalt to replace his dynamorphic generators. He brought two Concordes to his Citadel via a time contour. The second held the Doctor, his TARDIS and companions. He originally planned to use the captured passengers to break into the Sanctum and take control of the Xeraphin and add him to his TARDIS, but then he acquired the Doctor's TARDIS in a trade with him for a part the Doctor needed for his own TARDIS. The Xeraphin contacted Nyssa and let her and Tegan enter the Citadel, where the Master revealed his true form. The Master held the passengers hostage for parts from the Doctor's TARDIS. The second Concorde was returned to its own time and the Master ended up on Xeriphas with the freed and angry Xeraphin. (TV: Time-Flight)

The Master disguised as Sir Estram. (TV: The King's Demons)

On Xeriphas, the Master found and acquired Kamelion, a shape-changing android that could be easily controlled by a strong mind. Managing to elude Xeraphin, the Master escaped to England in 1215. (TV: The King's Demons) Killing the French knight "Sir Gilles Estram" to assume his identity, (PROSE: Sanctuary) the Master made Kamelion impersonate John of England to prevent the signing of Magna Carta. However, the arrival of the Doctor, Tegan and Vislor Turlough caused interference with his plans. After the Doctor defeated him in a mental battle of wits over the command of Kamelion, the Master fled in his TARDIS, (TV: The King's Demons) though with his link to Kamelion remaining active. (TV: Planet of Fire)

The Game of Rassilon

The Master is asked to save the Doctor by the High Council. (TV: The Five Doctors)

When the High Council of the Time Lords discovered that the first five incarnations of the Doctor had been time scooped and taken into the Death Zone on Gallifrey, they asked the Master for help, and offered him a new cycle of regenerations as a bargaining tool. He agreed and was given a copy of the Seal of the High Council by the Castellan to prove his credentials. However, the Third Doctor did not believe the Master, even blaming him for their being in the Death Zone, and took the seal from him on the pretence that he would return the "stolen property" to the High Council.

The Master soon encountered the Fifth Doctor, who also had trouble believing him, especially when he claimed that the Third Doctor had taken his only proof. Before he could further attempt to gain his trust, a group of CyberNeomorphs ambushed them, with the Doctor using the Master's recall device to escape and meet with the High Council when the Master was knocked out. Upon waking up, he formed a temporary alliance with the Cybermen to guide them to the Dark Tower, although it was clear they would kill him once he was no further use. After he let the Tower's traps slaughter the Cybermen, he hinted to the First Doctor how to get past security, but then grew power-hungry at the mention of immortality, and prepared to kill the first three incarnations of the Doctor, still angry at the Third Doctor for refusing to believe him when he genuinely offered his assistance. Alistair Gordon Lethbridge-Stewart knocked him unconscious in a surprise attack and Sarah Jane Smith and Tegan Jovanka bound him with rope. After the true mastermind of the plot, Borusa, was encased in Rassilon's tomb, Rassilon sent the Master back to his own time, promising that "his sins [would] find their punishment in due time". (TV: The Five Doctors)

After the Game of Rassilon

{{Section stub|Information from ''[[Birth of a Renegade (short story)|Birth of a Renegade]]'', & ''[[A Town Called Eternity (short story)|A Town Called Eternity]]'' needs to be added}}

While Rassilon had allowed the Master to escape Gallifrey unscathed, (PROSE: CIA File Extracts) he was quickly captured by the Time Lords, who, as punishment for his failure to help the Doctor in the Death Zone, destroyed the Master's Trakenite body, reducing him to little more than a helpless phantom as they exiled him to the depths of a forest. The Master was found by his TARDIS after it managed to resist the Time Lords attempt to reprogram it, and it helped him to attain physicality in the form of a shadowy figure in dark robes.

In an attempt to trap the Doctor and steal one of his remaining regenerations, the Master faked his own death, ensuring the Doctor would attend the funeral at the nursing home where he supposedly spent his final days. His plan was to force a regeneration out of the Doctor and steal this one life to revive himself using an arcane ritual involving twelve mirrors, but the Doctor was saved by Vislor Turlough, and the Master's plan was foiled yet again. Instead, the Master found himself confronting mental projections of all his past regenerations. In a prowess of will that impressed even the Doctor, the Master was able to overpower the shades of his past selves and steal a bit of life energy from each of them, allowing him to regenerate back into his Trakenite body. (PROSE: The Velvet Dark)

The Master allies with the Cybermen. (PROSE: Birth of a Renegade)

The Master burns in Numismaton Gas. (TV: Planet of Fire)

When the Master developed a more powerful version of the Tissue Compression Eliminator, he accidentally shrank himself and his lab to the size of a shoe box, without the ill effect of death. Using a device to boost his telepathy, the Master resorted to making telepathic contact with Kamelion and possessing him from afar, using his shapeshifting body as a proxy to try to restore himself. made contact with Kamelion once more, directing him to use the Doctor's TARDIS to land on Sarn. With Kamelion acting as his physical proxy, the Master had him pretend to be the locals' god and order the Doctor's death. When this failed, he had Kamelion take the small box his lab had become and take it to the lab on Sarn that used Numismaton Gas, hoping it could restore him. As the Master stood in a gas vent and returned to normal size, the Doctor used the gas to apparently burn him to death. (TV: Planet of Fire) However, the Numismaton Gas increased the power of the Source of Traken still remaining in the Master's body, enabling the Master to survive, (PROSE: The Quantum Archangel) though horrifically burned, forcing the Master into a search for the Fountain of Youth to restore himself. (PROSE: A Town Called Eternity)

Using his link to Kamelion, the Master attempted to psychically interfere with the Doctor's fifth regeneration, (AUDIO: Winter) urging the Doctor to die from his spectrox toxaemia, (TV: The Caves of Androzani) but was foiled by Nyssa. (AUDIO: Winter)

Interfering in history

{{Section stub|Information from ''[[Master Faustus (short story)|Master Faustus]]'', & ''[[Crossing the Rubicon (comic story)|Crossing the Rubicon]]'' needs to be added}}

The Master works with the Rani. (TV: The Mark of the Rani)

The Master allied with his old Academy classmate, the Rani, in Killingworth against the Sixth Doctor and Peri Brown; the Master hoped to hasten the advancement of Earth's technology for his own nefarious reasons, while the Rani wanted the brain chemical that induced sleep in humans. The Doctor trapped the Master and the Rani in the Rani's TARDIS, which the Doctor had sabotaged, with the time spillage putting them in danger of being eaten by a tyrannosaurus rex. (TV: The Mark of the Rani) The Master separated the Rani's console room from the rest of her TARDIS, freeing himself while leaving the Rani to drift aimlessly through the vortex. (PROSE: State of Change)

The Master and Christopher Marlowe face the Daleks. (PROSE: Master Faustus)

Interfering in the Doctor's trial

The Master materialised in the Matrix and observed the Doctor's trial on Space Station Zenobia, while examining the Matrix footage himself to see what was tampered with. Learning that the Valeyard was an "amalgamation of the darker side of [the Doctor's] nature", the Master decided that the Valeyard was a bigger threat and rescued the Doctor by supplying the Doctor with witnesses in the form of Melanie Bush and Sabalom Glitz, and revealing himself to the court as a surprise witness. Using Glitz as a tool, the Master tried to steal secrets from the Matrix, but was beaten by the Valeyard, and imprisoned in the Matrix by a limbo atrophier with Glitz. (TV: The Ultimate Foe) The Time Lords released the Master and Glitz from the Matrix, whereupon the Master killed the technicians and fled in his TARDIS. (PROSE: Mission: Impractical) After escaping, the Master could regenerate his body because the Source of Traken still existed within him. (PROSE: The Quantum Archangel)

Exiled on Alexis

The Master was exiled to the planet Alexis by the Time Lords. In his exile, the Master observed the life forms of the planet, the Mogellans, and saw how they were all connected in one great environment, and how they used special crystals to communicate. When a Kotturuh woman arrived on the planet, the Master pretended to intercede for the Mogellans' salvation, and they gave him one of the crystals as a token of good faith. The crystal, however, revealed to them that the Master was lying in order to exploit the crystals in the future, and they allowed the Kotturuh to end their lives to stop him. (AUDIO: Lesser Evils)

Haunted by the past

After escaping from an unsuccessful alliance with the Krotons, the Master was attacked by Chronovores looking for revenge for his torture of Kronos, and discovered that the last remnants of the Source of Traken were fading, reducing him to his previous cadaverous form. The Master devised a plan to destroy the Chronovores and achieve omnipotence by trying to access the Lux Aeterna using the TITAN Array. He stole the equipment and used it on a woman he hypnotised, Anjeliqua Whitefriar, expecting it to destroy her before he used it. However, she absorbed the Lux Aeterna, achieved omnipotence and became the Quantum Archangel.

Using her power, she filled the universe with too many alternate timelines, leading the Chronovores to feast upon them, eventually leading to the end of the universe. The Master and the Doctor teamed up to rectify the Master's mistake by defeating the Quantum Archangel. They discovered that the Quantum Archangel had allied itself with the Mad Mind of Bophemeral so it could have infinite knowledge of the universe. The Doctor and the Master encountered Kronos, who claimed to have been the one who attacked the Master's TARDIS, so he would come up with his plan, and would eventually lead to the Master's destruction as well as allowing Anjeliqua to survive, causing Kronos' plan for revenge to go wrong. They succeeded by draining the Lux Aeterna out of her, although not before the Master escaped using the TITAN equipment to harness the Lux Aeterna to restore his Trakenite body. (PROSE: The Quantum Archangel)

The Master pulls back his disguise. (COMIC: The Abominable Showmen)

The Master was greeted by a Missy, who had developed a plan to form a band to hypnotise viewers of The Battle of the Bands Beyond the Stars. His "Decayed", "Bruce" and "Saxon" incarnations all joined in the plan, and the team spent "decades" practising. (COMIC: The Five Masters) After unveiling their presence to the Twelfth Doctor and Clara Oswald, (COMIC: The Abominable Showmen) the Masters prepared for their performance. However, the "Tremas" Master began to fight with Missy over the possession of her device, believing that he alone could hold the universe in his grasp. The other incarnations joined in the fight, and the five were eventually disqualified, seemingly destroying them. (COMIC: The Five Masters)

The Master in the virtual body of "Keith Potter". (AUDIO: The End of the Line)

After the Master discovered the Parallel Sect, he possessed the body of Keith Potter, wanting to dominate the dimensional nexus. He found the Valeyard, and encountered the Doctor and Constance Clarke. After the Doctor defeated him, the Master was confronted by the Valeyard, who threatened him, forcing the Master to both leave the nexus and never return and to leave the Doctor alone, as the Valeyard had a plan to deal with him. (AUDIO: The End of the Line)

The Master is shocked to see a future incarnations with a baby. (POEM: Winning)

Alongside the Tremas Master and the Saxon Master, the Master reacted with shock when Missy presented the three Masters with her infant child. (POEM: Winning)

Alliance with Adam Mitchell

The Master reveals himself to the Sixth Doctor. (COMIC: Façades)

After meeting Adam Mitchell, a companion who had betrayed the Ninth Doctor, the Master began working to help him take revenge on their common enemy. (COMIC: The Choice) Together, they set up an asylum in 7214 with Autons as staff as a trap for the Sixth Doctor, Peri and Frobisher. The Doctor broke out of his cell thanks to Peri and Frobisher and melted the Autons. The Master escaped by tripping up the Doctor, leaving Adam to capture Peri. (COMIC: Façades)

The Master reveals himself to the Seventh Doctor. (COMIC: Cat and Mouse)

Using a group of Aeroliths to further his alliance, the Master syphoned their life force, to transmit to Adam, using a Gulwort. However, when they were freed by the Seventh Doctor, they chased after him. (COMIC: Cat and Mouse) After being tortured by the Aeroliths, the Master escaped, and, reunited with Adam, encountering the Eleventh Doctor. Discouraging Adam from listening to the Doctor, the Master watched in satisfaction as Adam prepared to kill the captured companions, (COMIC: The Choice) but was prevented when the Doctor summoned his earlier incarnations and revealed that he had arranged for Frobisher to infiltrate the plan by allowing himself to be captured while posing as Peri.

The Master and Adam capture the Eleventh Doctor. (COMIC: The Choice)

The Master and Adam released an Auton army, but the Doctors were able to keep them occupied long enough for Frobisher to release the other companions as reinforcements. However, unbeknownst to Adam, the Master planned to destroy reality itself, using the merged TARDIS that brought the Doctors there to channel chronon energy in a massive backlash that would unmake history. Convinced by the Doctors, Adam stunned him, but the Master stabbed him with a hidden knife. The injured Adam managed to foil the Master's plan, but died in the attempt. The Master then fled by teleporting away, satisfied by his role within all the chaos. (COMIC: Endgame)

The Cheetah World gambit

Infected with the Cheetah virus, the Master threatens the Doctor. (TV: Survival)

After trying to start a war between Antari Two and Antari Three, (PROSE: First Frontier) the Master went to the Cheetah World, where he took control of the Cheetah People and the kitlings. (TV: Survival) The Master used the Cheetah People to ambush the Seventh Doctor and Ace by kidnapping some friends of the Doctor, but he was entombed in an avalanche caused by the Doctor when he came to save his friends. (PROSE: Dr. Seventh)

As exposure to the planet began changing the Master into a Cheetah Person, he sent the kitlings to Ace's home in the London suburb of Perivale to hunt for human recruits. Eventually, he found a pliable young man called Midge, and used him to escape. Using Midge as his "hunting dog", the Master recruited a gang of Perivale youths to defeat the Doctor and Ace. The Master killed Midge and teleported the Doctor to the Cheetah World, which had begun to break up. The Doctor escaped, but the Master was trapped on the dying world. (TV: Survival)

After Cheetah World

The Master sabotages the Doctor's TARDIS. (PROSE: How did this creep get in here, Professor?

The Master was depositing inside the Doctor's TARDIS when the Cheetah Planet exploded, with its destruction apparently curing him of the Cheetah virus, due to the last effects of the virus responding to his desire to travel in time freely again, since he "had to go somewhere" but did not call any place home. The Master quickly hijacked the TARDIS by stealing the Identity Recognition Module as he set some time coordinates and then damaged the controls to prevent the Doctor from interfering, essentially shanghaiing Ace and the Doctor to an unknown destination aboard their own ship. (PROSE: How did this creep get in here, Professor?) However, the Master was seen multiple times still infected by the Cheetah Virus after escaping the Cheetah World, (PROSE: Stop the Pigeon, Prime Time) until, no longer infected by the virus, he lost Tremas's body and reverted to his previous cadaverous form. (AUDIO: Dust Breeding)

The Master is placed on trial by the Daleks. (TV: Doctor Who)

In another account, the Master himself contradictorily claimed that he was immediately stranded on Earth after escaping, and was then cured by Tzun nanites and regenerated into a new body. (PROSE: First Frontier) In an even more contradictory account, on a desert planet on the fringes of Mutter's Spiral, the Master, driven further insane by his defeat on the Cheetah Planet, obtained and swallowed a Deathworm Morphant from the Morgs. He then surrendered himself to the Daleks. (PROSE: The Eight Doctors) According to this account, the Master was then tried and executed by the Daleks, making a request for the Doctor to return his remains to Gallifrey, only to use the Deathworm Morphant to take the Doctor's TARDIS to 1999 San Francisco, where he possessed the body of an ambulance driver. (TV: Doctor Who) Missy herself admitted that her memory of what happened after being left stranded on Cheetah World was vague at best, to the extent that she was unsure said event had even taken place. (PROSE: Meet Missy!)

Fighting the Cheetah virus

In the year 2067, the Master tried to stave off the effects of the Cheetah virus by posing as a "Dr. Howard Chithros" and draining the life from his elderly patients. The Seventh Doctor discovered the scheme, and the nursing home was destroyed in the ensuing confrontation between him and the Master, who escaped in the confusion. (PROSE: Stop the Pigeon)

The Master attempted to gain a new body from a legendary race known as the Fleshsmiths, claiming that the Cheetah virus would kill his Trakenite body within a year, but his plan was stopped by the Doctor, who ejected the new body from the Fleshsmith vessel into space. (PROSE: Prime Time)

Reduced to an old body

The Master's masked disguise as "Mr. Seta". (AUDIO: Dust Breeding)

After having his Trakenite body stripped from him, and reduced to his previous decaying form, by the Warp Core, the Master collected four Krill eggs with the intention of awakening the Warp Core from its slumber and exhausting it, so that he could draw it into his TARDIS to be his slave. The Master then used a mask to disguise his deformity and followed the Warp Core as it arrived on Duchamp 331. Under the alias "Mr. Seta", the Master funded Madame Salvadori's trip to Duchamp 331, where the Master unleashed the Krill upon the passengers, hypnotising Salvadori's aide, Klemp, in the process. Revealing his true identity, the Master kept Salvadori alive, before encountering the Seventh Doctor. When the Core arrived, the Master tried to ally with it, but it dismissed him, leading him to ordering Klemp to kill Salvadori, but Klemp's loyalty was too strong, so the Master killed him. The Doctor escaped to his TARDIS, and attempted to gain control of the Warp Core through his TARDIS's telepathic circuits, while the Master used his TARDIS to fight of the Doctor's influence and gain control of it. After it and the planet were destroyed, the Master was flung through time and space. (AUDIO: Dust Breeding)

Living a peaceful life

The Doctor made a deal with Death for the Master to have ten years of peace and sanity, at the end of which the Doctor had to kill him. To this end, Death transformed the Master into "John Smith", an ordinary physician on the colony world of Perfugium with no memory of his past. Smith was taken in by Wolstonecroft, and inherited his house when Wolstonecroft died, and became emotionally involved with Jacqueline Schaeffer. The Master remained active in Smith's subconscious, but was unable to influence the world around him.

At the end of the allotted time, the Doctor arrived to kill Smith, but strove to avoid fulfilling his side of the bargain. Death herself was present at these events, disguised as Smith's maid, and manipulated events so that the Master would become dominant once more. Her endgame was for Smith to make a decision that would ensure he remained in control; to kill Victor Schaeffer or allow Jacqueline to die by her husband's hand, but Smith was unable to kill Victor, (AUDIO: Master) and became the Master again as a result. (PROSE: The Tramp's Story)

Capturing the Doctors

The Master temporarily victorious in capturing the first seven incarnations of the Doctor. (GAME: Destiny of the Doctors)

Looking much older with greying hair, the Master captured the first seven incarnations of the Doctor and put them into a void called the Determinant. However, the Graak successfully freed the Doctors and the Master was captured and imprisoned by one of the races involved in his game. (GAME: Destiny of the Doctors)

A new regeneration

Let... me... be... free...The "Tremas" Master's last words

According to one account, the Master became trapped on Earth without his TARDIS in the year 1957 after escaping the destruction of the Cheetah Planet by using a kitling named Shadow to transmigrate just as the planet exploded. The Master interrupted the first Soviet satellite launch and sent a distress signal to the Tzun Canton on Zeta Reticuli Four. He offered to help assimilate Earth into the Tzun Confederacy. In return, the Master asked for passage off Earth and the use of the Tzun's genetic engineering to cure his Cheetah virus infection. The Tzun accepted and prepared nanites for him that broke down the corrupted Trakenite DNA in his cells and restructured it. This was meant to restore the Master to being a "full" Time Lord, giving him a new regenerative cycle and curing the Cheetah virus. Shortly after being restored to his full Time Lord heritage, he was shot in the back by Ace to avenge his murder of Joe Manco, causing him to regenerate. (PROSE: First Frontier)

Post-mortem

The "Tremas" Master's laughter was heard by the "War" Master whilst he was still under the powers of the Chameleon Arch. (TV: Utopia)

Undated events

• The Fifth Doctor believed that the Master was responsible for the Sea Base 4 incident, (PROSE: A Sourcebook for Field Agents) in which the Silurians and Sea Devils attacked Sea Base 4 in 2084. (TV: Warriors of the Deep)

Other realities

Parallel universes

In an alternative universe created by the Quantum Archangel, the Master joined the Time Lords to fight in the War. However, he began aiding the Daleks by giving them temporal manipulation technology. The Sixth Doctor, who was Lord President Admiral of Gallifrey, activated the Armageddon Sapphire and destroyed the universe rather than letting the Enemy win.

In a different alternative universe created by the Archangel, the Master cooperated alongside the Rani, the Monk and Drax to try to destroy the world using a DNA recombinator, turning the human race into a gestalt consciousness which could be used as a weapon to conquer the universe. (PROSE: The Quantum Archangel)

Psychological profile

Personality

The Master threatens the universe. (TV: Logopolis)

After possessing Tremas's body, the Master became a more flamboyantly evil, bombastic and sophisticated individual, (TV: Logopolis, Castrovalva, Time-Flight, The King's Demons, The Five Doctors, The Ultimate Foe) who only put trust in himself. (TV: The Mark of the Rani) He was prone to laughing maniacally and reciting lengthy and verbose speeches, accompanied by melodramatic gestures and poses. (TV: Time-Flight, The Five Doctors, The Mark of the Rani) The Seventh Doctor even recalled the Tremas Master as having "a taste for melodrama." (AUDIO: The Two Masters)

The Tremas Master was unwilling to share any form of power with others, often betraying those he worked with to accomplish his own goals, (TV: Logopolis, The Five Doctors, The Ultimate Foe, Survival) even when working with his other incarnations. (COMIC: The Five Masters) However, he was willing to accept when he had acquired the necessary amount of resources he needed, albeit reluctantly. (PROSE: A Master of Disguise)

The Tremas Master was devoted to killing the Doctor, often employing elaborate gambits and strategies to this end. (TV: Castrovalva, The Mark of the Rani) However, he mused that a cosmos without the Doctor "scarcely [bore] thinking about", and was willing to join forces with the Doctor if he viewed it as beneficial to himself. (TV: Logopolis, The Five Doctors, The Ultimate Foe) He voiced an enjoyment for the Doctor's company, viewing him as a worthy opponent, and mused about keeping the Seventh Doctor's corpse as a "memento". (AUDIO: Dust Breeding)

He showed a genuine disregard for life and was often uninterested in how many people died at his hands, (TV: Logopolis, Castrovalva, The King's Demons, Survival) and had a particular fondness for the Tissue Compression Eliminator. (TV: Logopolis, Time-Flight, Planet of Fire, The Mark of the Rani) However, he showed an unusual level of moral standards when he apologised to Peri Brown for involving her in a battle that was originally supposed to be between him and the Sixth Doctor, and was genuinely horrified when the Rani's contraption turned Luke Ward into a tree, although the Doctor considered it an example of how warped and callous the Master was if he thought that establishing that Luke's death was an accident was any kind of excuse. (TV: The Mark of the Rani) He was also horrified upon witnessing the Kotturuh judgement on Alexis. (AUDIO: Lesser Evils)

When someone proved useful to him and his plans, the Master, though unwilling to disguise his cruelty, would be more accommodating to them, both as a way of manipulating them and as a show of gratitude to their effectiveness and loyalty. (PROSE: A Master of Disguise)

The Master was delighted and satisfied when Lord President Borusa addressed him as "one of the most evil and corrupt beings [the] Time Lord race [had] ever produced", but was surprised and outraged when his attempts to convince the Third Doctor of his sincerity was ridiculed and spurned. (TV: The Five Doctors) He also thanked Mel Bush when she remarked on how "evil" he was. (TV: The Ultimate Foe) When the Seventh Doctor questioned the Master's decision to "act the villain", the Master stated he was "famed for [the] role", and claimed to enjoy the "typecasting". (COMIC: Crossing the Rubicon) However, when he was called "evil" by the Doctor, the Master objected that he "crave[d] power, dominion, [and] knowledge of the forbidden and the secret". (AUDIO: Master)

The Master on Cheetah World. (TV: Survival)

After he was infected by the Cheetah virus, the Master became more calm and calculating. However, as the virus took its toll, he became more animalistic and sadistic, taking satisfaction in murdering Karra and attempting to hit the Seventh Doctor's head with a club during their fight. (TV: Survival)

After losing his body to the Warp Core, the Master became a far darker person, but was calmer and well spoken, which made him sound more sinister. (AUDIO: Dust Breeding, Master) He seemed to enjoy being mysterious about his true identity and enjoyed giving his enemies riddles as to who he truly was. (AUDIO: Dust Breeding) When trapped in John Smith's subconscious, the Master was aware of Smith's activities, but was unable to influence them. He spent his time taunting Smith and trying to get him to indulge in his violent impulses. (AUDIO: Master)

The Tremas Master had various opinions of the first seven incarnations of the Doctor. He referred to the First Doctor as a "bore", the Second Doctor as an "incapable comedian", the Third Doctor as a "worthy foe", the Fourth Doctor as "the bohemian, [and] the wanderer", believed that the Fifth Doctor was "the nice one full of charm, innocence, and naiveté", described the Sixth Doctor as "the blustering one with the stupid coat", and that the Seventh Doctor was "too busy setting traps" to realise the ones "set for him". (GAME: Destiny of the Doctors)

Missy described the Tremas Master as being "the Sneaky One". (PROSE: Meet Missy!)

After he was shot in the back by Ace to avenge his murder of Joe Manco, the Master withered in extreme pain that he tried to fight while complaining about how close he was to victory. Clawing at his wound and grasping his head, the Master regenerated while cowering from the pain in his TARDIS, begging to be "free". (PROSE: First Frontier)

Skills

The Master reveals his contingency plan. (COMIC: Endgame)

Unlike his predecessor, the Tremas Master seemed unable to use natural hypnotism, instead using an Electro-muscular constrictor to enslave Nyssa, (TV: Logopolis) causing misdirection to discredit the Fifth Doctor at Fitzwilliam Castle, (TV: The King's Demons) and took control of Luke Ward by combining hypnotic suggestion via a crystal necklace with the Rani's mind parasites. (TV: The Mark of the Rani) When his attempts to hypnotise Sabalom Glitz with a swinging silver pendant failed due to Glitz's mind being occupied with calculating the wealth of the pendant, the Master resorted to offering Glitz a chest full of jewellery to ensure his cooperation. (TV: The Ultimate Foe)

The Tremas Master was able to accurately predict the Doctor's movements, implementing multiple ways to kill him and manoeuvring him into them with relative ease, (TV: Logopolis, Castrovalva, The Ultimate Foe) and was was able to improvise when things turned awry. (TV: Logopolis, The Five Doctors, Survival) The First Rani even believed that his plans were so overcomplicated that he would get dizzy if he walked in a straight line. (TV: The Mark of the Rani)

Appearance

The Master in Tremas's body. (TV: Logopolis)

After the Master used the power of the Source to steal Tremas's body, the Trakenite's body was also rejuvenated, with his grey hair becoming a dark brown, and his white bushy beard turning into a black goatee beard. (TV: The Keeper of Traken) The Fifth Doctor had a low opinion on the beard, calling it "rubbish" when he met his tenth incarnation. (TV: Time Crash)

After the Master stole his body, Tremas's robes inexplicably changed into a black velveteen high collared tunic with puffed sleeves and long tails, (TV: The Keeper of Traken) black trousers, dark leather boots, and black velvet gloves. (TV: Logopolis) The Master would also utilise a cloak with a large collar. (TV: The Five Doctors) By the time he became stranded on Cheetah World, the Master was wearing a black collarless silk jacket, a navy blue shirt with an ivory collar, a midnight blue bow tie, black trousers and shoes, a silver waistcoat with the collar coming out over the collarless jacket, and a belt with a dragon-shaped buckle. (TV: Survival)

The Master lives as "John Smith". (AUDIO: Master)

When the Master was robbed of his Trakenite body by the Warp Core, he regained his disfigured appearance, which Ace described as resembling Freddy Krueger and "a dropped pizza". To hide his disfigurement, the Master took to wearing a golden mask with diamonds encrusted inside it. (AUDIO: Dust Breeding) After becoming John Smith, the Master did not hide his disfigurement and wore a suit instead. (AUDIO: Master)

In an account that depicted the Tremas Master with greying hair, he wore a red velvet jacket with a popped collar, a silver waistcoat with a black turtleneck, and a pair of dark trousers, with leather gloves and shoes, with various rings decorating his gloves. Completing the ensemble was a black cloak with a huge collar and white lining, (GAME: Destiny of the Doctors) which the Master had also worn during his alliance with Adam Mitchell. (COMIC: Cat and Mouse)

While combating the Graak in the Determinant, the Master adopted many costume changes to suit the situation he found himself in; wearing an a conductor hat with an "M"-insignia at a platform station, a bowler hat while on a train taunting the Graak, a Dalek Trooper helmet while commanding a rocket launcher, and a plastic crown at a medieval themed festival. (GAME: Destiny of the Doctors)
