"The Master" — known in female form as "Missy", short for "Mistress", and at times by various other aliases — was a renegade Time Lord, a power-hungry "lover of chaos" who served as both a friend and an opponent of the Doctor.

Friends from childhood and schoolmates at the Time Lord Academy, the divide between the Master's lust for power and the Doctor's empathy for lesser species would eventually pull the two farther and farther apart — to the point that the Master often sought to kill the Doctor. Despite this enmity, however, the two would on occasion act as allies, and both continued to yearn for their old friendship.

Like the Doctor, the Master fled from Gallifrey in a TARDIS of his own, and, having fully embraced his darker nature, would go on to pit himself against the Third Doctor and UNIT during the Doctor's exile on Earth. Having expended his original regeneration cycle, the Master survived in the ghastly form of a living cadaver, in which form he fought the Fourth Doctor, before exploiting the powers of the Source on Traken to steal the body of Tremas. He would continue his crusade to submit the universe to his will in a variety of stolen or otherwise-fraudulent bodies, from using Tzun nanites in order to gain new regenerations, to transferring his essence into a Deathworm Morphant, which allowed him to survive execution by the Dalek Prelature, and continue to survive by possessing a succession of human bodies.

Finally killed by the Ravenous, the Master was eventually restored to life for good, on the instructions of the Time Lords in preparation for a future conflict with the Daleks. After working with the War Doctor in the body of a child during the Time War, the Master regenerated into an older body that tried to manipulate the conflict to suit his own goals. However, after his failure to end the war using the Heavenly Paradigm, resulting in even more devastation across the timeline, the Master was driven to such a state of terror that he fled to the end of the universe and turned himself into a human baby with a Chameleon Arch. After spending many years living as a humble human scientist on Malcassairo, the Master's personality was reawakened by Martha Jones, and, fatally shot by Chantho, he regenerated into a younger body.

Using the alias "Harold Saxon", the Master engineered his election as Prime Minister of the United Kingdom in the 2008 elections, and then sought to use the Earth to create a new Gallifrey. When his plan was foiled, he was shot by his wife, Lucy, and decided not to regenerate and die to spite the Doctor. Following a faulty resurrection by the Disciples of Saxon, the Master used the Immortality Gate to create the Master Race and attempted to free Gallifrey from the time lock of the Last Great Time War, but instead entered the last day of the war to get revenge on Rassilon.

After Gallifrey returned to the universe, the Master left, and eventually ended up on a Mondasian colony ship, where he came face-to-face with a future female incarnation of himself, who stabbed him to ensure his regeneration into her. Now a woman, the Master began to call herself "Missy", the self-proclaimed "Queen of Evil". Missy went through many chaotic adventures of her own throughout the universe, but, although she loudly denied having "turned good", she demonstrated a willingness to rekindle her friendship with the Twelfth Doctor.

Eventually, Missy was captured and imprisoned inside a Quantum Fold Chamber, which was moved into a vault at St Luke's University by the Twelfth Doctor and Nardole. Although she claimed she could leave the Vault anytime she wanted to, she chose not to because she wanted to become good. So the Doctor tried to rehabilitate her and rekindle their friendship on his terms. On the verge of changing, Missy was sent on a trial adventure with Bill Potts and Nardole, but joined with her previous incarnation when it all went wrong. In the end, she betrayed and killed her past self in order to finally stand by the Doctor, but was killed herself in retaliation before she could reach him, with both believing that this had been their "perfect ending". However, Missy managed to regenerate into a benevolent incarnation who called herself "the Lumiat".

After the Lumiat was killed by Missy, she regenerated into a male incarnation who called himself "the Master" again, and discovered in the Matrix that the entire Time Lord history had been "built on the lie" of the Timeless Child, which involved the true origin of the Doctor. Embittered by his discoveries, and lashing out from the belief that the Doctor had always been more than he was, the Master took his revenge on Gallifrey, leaving it in ruin. He next turned to plague the Thirteenth Doctor and Team TARDIS, eventually revealing the truth about the Timeless Child and building an army of CyberMasters from the remains of the Time Lords he had killed, becoming the host of the Cyberium consciousness to make himself their commander. However, his plot was thwarted when Ko Sharmus detonated the death particle on Gallifrey.

Biography Edit

Early life Edit

The Master grew up on Gallifrey in the House of Oakdown, (PROSE: Divided Loyalties) though he would later comment to Wilfred Mott that growing up on Gallifrey was not something one could call childhood, but "more a life of duty". (TV: The End of Time) The name he was born with was unknown and apparently consisted of thirty-two letters. (PROSE: Lords and Masters)

Like all Time Lords, the Master was taken from his family at the age of eight for the selection process. (PROSE: A Brief History of Time Lords) During the ceremony in which he gazed into the Time Vortex through the Untempered Schism, he went mad, (TV: The Sound of Drums) due to a rhythm of four beats being implanted into his head. (TV: The End of Time) This malady manifested itself as the constant drumming he heard ever after, worsening with time. (TV: Utopia, The Sound of Drums, Last of the Time Lords)

Academic career Edit

The Master and the First Doctor became friends on their first day at the Academy, (TV: World Enough and Time) with both being tutored by Borusa, (AUDIO: Masterplan) and the Doctor quickly developing a "man-crush" on his new friend, (TV: World Enough and Time) which the Master was partially aware of. (AUDIO: The Bekdel Test) The duo also made a friend in the War Chief on their first day at the Academy. (PROSE: Divided Loyalties)

Sharing the same heritage and upbringing, (AUDIO: Dominion) the Master developed a strong bond with the Doctor, (TV: The Sea Devils, The Sound of Drums, World Enough and Time) with UNIT scientist Osgood even describing the Master as the Doctor's "childhood friend". (TV: Death in Heaven) The Second Doctor recalled that he and the Master had everything in common, except that the Master enjoyed being scared of the dark "a little too much", (PROSE: The Menagerie) while the Third Doctor told Jo Grant that the two were "inseparable" due to their shared interests, such as a desire to break the non-interference policy. (PROSE: Doctor Who and the Sea-Devils) The Twelfth Doctor recalled how he and the Master had a pact to explore every star in the universe together. (TV: World Enough and Time) The Master and the Doctor enjoyed building "time flow analogues" to disrupt each other's experiments. (TV: The Time Monster)

The two youths would play in the fields near the Master's father's estates, with pastures of red grass near Mount Perdition. (TV: The End of Time) They would also sneak out of the Capitol and drink with the Shobogans, (PROSE: The Eight Doctors) with the Master picking a fight with six drunken Shobogans during one of these outings. (PROSE: UNIT Christmas Parties: Christmas Truce) The Master also taught his friend hypnotism, and would often hypnotise people as a joke, (PROSE: The Dark Path) but would go unpunished for it, as well as other misdemeanours, always finding a way to avoid his comeuppance. (PROSE: First Frontier)

During their childhood, the Master and the Doctor were mercilessly and viciously bullied by a boy called Torvic; the Doctor was eventually forced to kill the bully to save his friend's life. The Doctor was later confronted by the personification of Death, who insisted he become her disciple, but the Doctor refused and suggested Death make the Master her champion instead. Death agreed, and the Doctor subsequently forgot about their deal. (AUDIO: Master)

According to a dream the Fifth Doctor had under the control of the Celestial Toymaker, the Master went by the name "Koschei" at the Academy and belonged to a clique of ten young Time Lords with the collective name of the Deca. (PROSE: Divided Loyalties) He was also part of the "Gallifrey Academy Hot Five" band, in which he played the drums. (PROSE: Deadly Reunion) The Master was in charge of organising end of term parties, although the Eighth Doctor later noted that they weren't very good. (COMIC: The Glorious Dead)

The Master chose his title while he was beginning to "hone his talents" at the Academy. (AUDIO: The Destination Wars) The Doctor chose his around the same time. The Master felt that the name the Doctor chose was "sanctimonious", (TV: The Sound of Drums) while the Doctor thought the Master's new name was a sign of his ambition and arrogance. (AUDIO: The Destination Wars) The Tenth Doctor once stated that it would be a "psychologist's field day" understanding why he chose to call himself "the Master". (TV: The Sound of Drums) According to one account, he gained the nickname of the "Master" in his Academy days, and was a bully to less domineering students than himself. (PROSE: The Legacy of Gallifrey)

Whilst at the Academy, the Doctor and the Master travelled into Gallifrey's past in search of Valdemar. They found nothing of the Old Ones except for warnings. The Master was fascinated by the power that Valdemar represented, while the Doctor was horrified. (PROSE: Tomb of Valdemar) The Master also showed a fascination with the Necronomicon. (PROSE: The Nameless City)

At the Academy, the Master was a "teacher's pet" and won gold stars, while the Doctor was the class dunce, (PROSE: Time and Relative) though the Doctor was Borusa's favourite. Ultimately, the Master did not perform well at the Academy. Despite being better at metabolic control, (AUDIO: Masterplan) and earning a higher degree in cosmic science than the Doctor, (TV: Terror of the Autons) he was not skilled in practical matters, (PROSE: The Legacy of Gallifrey) and the Doctor's grades were overall better than his. Because of this, the Doctor received the prizes and praise that the Master so desperately wanted. The Seventh Doctor theorised that this may have been the cause of the Master's hatred towards him, (PROSE: Survival) with Eighth Doctor believing that his jealousy over Borusa was the cause of the Master's hatred towards him. (AUDIO: Masterplan)

When the Time Lords created the Consolidator to conceal various dangerous historical secrets from the rest of the universe, unwilling to destroy the items or races in the ship in case they proved useful later, the Doctor and the Master were assigned to come up with a solution where their peers had failed. The Master had the idea of using a black hole to tear a rift in time and send the Consolidator into the distant future, where the future Time Lords could deal with it, but the Doctor declined to have his name put down on the calculations as he questioned the ethics of the assignment. However, when the experiment was actually attempted, the Consolidator was apparently destroyed by a mistake in the calculations when it struck the edge of the black hole, leaving the Time Lords to hush the matter up. (PROSE: Harvest of Time)

As the Doctor grew up, he came to understand that he and his friend were not the same. (TV: Death in Heaven) Following an incident at the Academy in which the Master did not keep his word, he and the Doctor had a falling out, (PROSE: Last of the Gaderene) eventually leading the Doctor to realise that the Master stood against everything he believed in. (AUDIO: The Destination Wars)

The Master was on an Academy research project when the Doctor was expelled from the Academy. (PROSE: Divided Loyalties)

In one of his earliest schemes at the Academy, the Master befriended one of his professors, Salyavin, to gain access to Gallifrey's most restricted libraries and find The Worshipful and Ancient Law of Gallifrey. The Master himself failed to find the book, and ended up letting the innocent Salyavin bear the consequences of his breach of Gallifrey's laws; Salyavin ended up stealing the book anyway, reasoning he might as well if he was to be blamed for it, (PROSE: The Legacy of Gallifrey) and was imprisoned on Shada, from which he later escaped, renaming himself "Professor Chronotis". (TV: Shada)

Life on Gallifrey Edit

Still maintaining a "friend[ship] of sorts", the Master and the Doctor were pioneers and inventors among their people. (AUDIO: The Destination Wars)

Missy claimed she had a daughter and that, while still on Gallifrey, the Doctor gifted the Master a dark star alloy brooch, after an event which involved his daughter occurred. (TV: The Witch's Familiar)

On Gallifrey, the Master had the job of truant officer, and he performed his job with punctuality, self-discipline, and meritorious conduct. (PROSE: Time and Relative) He once attended a ritual in Arcadia where he gave Susan a toy that was actually a disguised communication node that would locate the Doctor if he ever left Gallifrey. (AUDIO: The Toy) Susan was afraid of him. (PROSE: Time and Relative)

Fleeing Gallifrey Edit

On the day that the Doctor left Gallifrey, the Master was desperate to know where he went. (PROSE: Celestial Intervention - A Gallifreyan Noir) He used the node he gave Susan to locate the Doctor, but found that the node had established a connection with Nyssa, a companion of the Fifth Doctor. The Master tried to take control of Nyssa but was stopped by the intervention of the Doctor. (AUDIO: The Toy) When retired CIA agent Maris was hired to find the Doctor, the Master, helped by the Rani, used a chronal mine to kidnap her. They interrogated Maris on the whereabouts of the Doctor, and were displeased when she told them she didn't know. They were about to kill her when her employer extracted her from the area. (PROSE: Celestial Intervention - A Gallifreyan Noir)

The Master ultimately left Gallifrey on the same day the Doctor did, (COMIC: The Glorious Dead) in a Type-45 TARDIS, (PROSE: The Dark Path) that he had also stolen (COMIC: The Glorious Dead) when the Quadriggers were still working on it. (AUDIO: The Destination Wars) One Time Lord stated that the Master left Gallifrey because, like the Doctor, it was "too peaceful for [him], [with] not enough happening". (PROSE: Doctor Who and the Doomsday Weapon) The Fifth Doctor believed that the Master left Gallifrey because he was also leaving. (AUDIO: The Toy)

According to one account, when the Doctor escaped Gallifrey, the Master was in line for a promotion to Head Truant Officer, but his career depended on catching the Doctor and Susan and preventing any violations of the non-interference policy. (PROSE: Time and Relative)

According to another source, during a period of civil unrest on Gallifrey, the Master led many students of the Time Lord Academy in a revolt against the corrupt Lord President, Pundat the Third, and attempted to recruit the Doctor and convince him to take the position as President, but he decided not to interfere with the current constitution. When Pundat died of stress soon after the revolt, his chosen successor was the evil Chancellor Slann. The students had found the last of Lord Rassilon's descendants, Lady Larn, a seven-year old child adopted by Councillor Brolin, who was being groomed as a future president. They decided on a second coup, but were overheard by the authorities when trying to convert the Doctor again, and bloody reprisals against the students followed. The Doctor and Larn escaped from Gallifrey after this. Believing the students ready for another coup, the Master assassinated Lord President Slann. However, the students weren't ready and he took this opportunity to steal a TARDIS and flee Gallifrey as a renegade. (PROSE: Birth of a Renegade)

Early exploits Edit

Because his TARDIS was broken when he stole it, it fell apart around him almost instantly, stranding the Master on the furthest arm of a galaxy in the "earliest Segments of Time". He took charge of the planet Destination, assuming the title of "the Inventor", and developed the planet's technology for his own ends. He pitted the human colonists against the Dalmari, so that the colonists would develop the nuclear technology he planned to use to refuel his TARDIS's engines. When the First Doctor arrived, he changed his plans and tried to steal the Doctor's TARDIS to escape. He was able to trick Ian Chesterton and Barbara Wright into leading him to the ship, but they were able to overpower him and use the fast return switch to take the TARDIS back to Destination. The Master ultimately became trapped in his own laboratory after the Doctor had rerouted its power to help Destination to rebuild. (AUDIO: The Destination Wars)

On Segonax, the Master allied himself with the Gods of Ragnarok, and used a pendant they gave him to contact a street artist on Zamyatin named Kingpin and use Kingpin's free spirited energy to cause a psychic storm, which caused a revolution on Zamyatin. The Master then persuaded Kingpin to organise a collective of various artists and bring them to Segonax to become the Psychic Circus. The Master then persuaded the Chief clown to organise a talent contest so that new energy could be acquired. When Kingpin managed to contact the Seventh Doctor, the Master used his abilities to stop him from reaching the Circus, first creating an illusion of him landing on Zamyatin, and then one of him returning to Paradise Towers. When the Doctor eventually came to the Circus, he and the Master confronted each other on a psychic plane, where the Doctor exploited the Gods' curiosity to buy time to steal the pendant from the Master and pass it to Kingpin. Kingpin then used the pendant to free the Circus from the Master and the Gods' influence, and the Master was left at the mercy of the Gods of Ragnarok. (AUDIO: The Psychic Circus)

On arrival on a planet where human colonists had settled in a fictional recreation of an English village during the Second World War to live in peace away from Earth, the Master took control of the environment, organised a home guard and armed the original population of the planet to entice a conflict and demonstrate that an outgunned and outnumbered group of people could resist against a much greater enemy when properly motivated. When the Second Doctor arrived with Ben Jackson, Polly Wright and Jamie McCrimmon, the Master hypnotised them into joining his experiment. The Doctor, however, immersed himself too deep in his role of commander of the home guard and made contact with the aliens to reach a peaceful solution, resulting in the aliens attacking earlier than the Master had anticipated. In the ensuing battle, the Master escaped in his TARDIS, with the intent of returning to look on the results of the conflict. However, when he returned, the Doctor had already set a trap for him after persuading the fighters into a peace. The Master was captured and put on trial for illegal use of mind control, while his TARDIS was confiscated. (AUDIO: The Home Guard)

Arriving at the Scoundrels Club Edit

At some point, the Master regenerated for the first time and his new incarnation found himself at the Scoundrels Club during the Great Fire of London. Becoming a member of the club so that he could recover from the regeneration in comfort, the Master organised fireworks on the roof to celebrate the occasion. He visited the Scoundrels Club after each regeneration to recover as a tradition. (PROSE: Dismemberment) The Seventh Doctor recalled that the Master frequently used regeneration as an effective disguise during his exploits. (PROSE: Original Sin)

Nemesis of the Third Doctor Edit

Dealings with the Second Doctor Edit

At some point, the Master regenerated into an incarnation with a swarthy complexion, brown eyes, and a goatee beard with white skunk stripes. (TV: Terror of the Autons) He visited the Scoundrels Club to recover from the regeneration in comfort. (PROSE: Dismemberment)

Having begun calling himself "Koschei", the Master had a Time Lady named Ailla planted on him by the Celestial Intervention Agency to monitor his unstable obsession with order; Ailla posed as a human so Koschei would take her on as his companion during a stopover in the 28th century. Koschei caught up with the Second Doctor at the Darkheart colony in the early years of the Galactic Federation. The temptation posed by the Darkheart device, capable of altering timelines without causing paradoxes or attracting the attention of various "higher beings", proved too much for Koschei, and the revelation that Ailla was a spy killed the last traces of good in him, and he became "the Master". After the Doctor trapped him in a black hole, the Master swore that he would take revenge. (PROSE: The Dark Path)

The Master penetrated Gallifrey, and gained access to the Matrix via a console in the old Capitol. This gave him a backdoor into the Matrix, which he used to collect classified information for his many devious schemes, (PROSE: The Quantum Archangel) including the Time Lords' files on the Doomsday Weapon, (TV: Colony in Space) the Sea Devils, (TV: The Sea Devils) the Chronovores, the Dæmons, (PROSE: A Brief History of Time Lords) and the Deathworm Morphants. (PROSE: The Quantum Archangel)

The Master then put his TARDIS in orbit of the homeworld of the Archons and made a deal with them that would result in the Archons acquiring the Doctor's TARDIS for themselves. Posing as "Professor Thascalos", the Master gave the Necronomicon to the Doctor's companion Jamie McCrimmon, so that Jamie would give the book to the Doctor and lure the TARDIS to the Archon homeworld. (PROSE: The Nameless City)

According to one Time Lord, before arriving on Earth, the Master was responsible for several interplanetary wars, but always managed to disappear before he could be brought to justice. Though the Time Lords managed to catch him, the Master escaped before his TARDIS "could be de-energised." (PROSE: Doctor Who and the Terror of the Autons)

Early times on Earth Edit

The Master was imprisoned on Shada by the Time Lords at the time when the Doctor was exiled to Earth. However, the Celestial Intervention Agency arranged for the wardens of Shada to release him so as to keep the Doctor busy. Because they believed he would make short work of an unaware Doctor, they sent a messenger to forewarn the Doctor of the Master's arrival. (PROSE: Prisoners of the Sun)

The Master was present at the first Auton invasion of Earth, and heard about Channing's attempt to capture the Third Doctor. He contacted journalist James Stevens by phone, whose article he had read in the Daily Chronicle, and told him about the near-kidnapping. He called Stevens again during the Silurian attacks on Wenley Moor, informing Stevens that Edward Masters had been the first to die from the plague sweeping London. Shortly after the Inferno Project incident, the Master once more contacted James Stevens, this time to check up on his work on his UNIT article. He promptly hung up when Stevens mentioned C19 and the Glasshouse. (PROSE: Who Killed Kennedy)

Under the alias "Emil Keller", the Master captured a psychic parasite and trapped it within the Keller Machine, and spent many months establishing "Keller" and the machine's credentials. (TV: The Mind of Evil)

The Master first infiltrated the headquarters of UNIT while the Brigadier and the Doctor had gone to meet with government officials. He hypnotised the Doctor's assistant, Liz Shaw, and, through her, learnt of the failed Nestene invasion and the awakening of the Silurians. This inspired him to ally himself with the Nestene and to locate more Silurian colonies. (PROSE: Reconnaissance)

Becoming a threat Edit

The Master appeared at the International Circus, with his TARDIS in the form of a horse box. He hypnotised the circus troupe and plastic factory manager Rex Farrel to obey his orders as part of his plan to assist the Nestenes in their latest bid to conquer Earth. A Time Lord emissary alerted the Doctor to his rival's presence on the planet, and before the radio telescope could be used to bring the Nestene invasion force to Earth, the Doctor convinced the Master that the Nestenes would not distinguish between the Master and anyone else in their takeover, and the two worked together to fling the Nestenes back into space by "chang[ing] the polarity" whilst the radio telescope's transfer shift was still open. Afterwards, the Master fled. The Doctor, however, had already taken his dematerialisation circuit, preventing the Master from leaving Earth in his TARDIS. (TV: Terror of the Autons)

The Master returned again, posing as the scientist who had "developed" the Keller Machine. He used prisoners as a plan to hijack the Thunderbolt, a missile containing nerve gas and use it to destroy the World Peace Conference, which would trigger a nuclear war. The Doctor, with the help of Barnham, stopped the Master with the Keller Machine, and the Doctor reactivated the missile's abort mechanism. UNIT also destroyed the missile along with the Keller Machine, but the Doctor later discovered he had lost the Master's dematerialisation circuit in his altercation with the Master. Shortly after, the Master telephoned to let it be known that he had found the circuit and was free now to come and go as he pleased, while the Doctor had to remain in exile. (TV: The Mind of Evil)

Shortly after the Master regained control over his TARDIS, he tried to gain control of a cult so he could harness the power of the Immortals. He convinced the real cult leader, Hadley, that he could serve the cult loyally, by supplying them with sarg. Unfortunately for the Master, Hadley only intended to keep the Master alive while he was still useful. With no other options, the Master formed a temporary truce with the Doctor to stop Hades' plan. After the crisis was resolved, the Doctor allowed the Master to depart unmolested in the name of their temporary truce. (PROSE: Deadly Reunion)

The Master brought Axos to Earth, hoping to ally himself with them. Instead, he became the prisoner of Axos, and only escaped by saying that he would help it. The Doctor tricked the Master into thinking he was going to betray Earth. Instead, he trapped the Master with Axos in a time loop. (TV: The Claws of Axos) Posing as an Adjudicator, the Master travelled to a human colony on the planet Uxarieus in the year 2472. There, the Time Lord records indicated he would find the Doomsday Weapon created by a near-extinct native species. Once again the Doctor defeated his plans and the weapon was destroyed. (TV: Colony in Space)

Posing as a vicar named "Victor Magister" in the village of Devil's End (TV: The Dæmons; PROSE: Who Killed Kennedy) after murdering the old vicar, Canon Smallwood, (PROSE: The Eight Doctors) the Master summoned the ancient Dæmon Azal, but he failed to understand the power and control that was necessary following summoning him. Following Azal's confrontation with Jo Grant's selflessness, Azal destroyed himself through Jo's illogical actions. The Master was captured by UNIT following a failed attempt to escape in the Doctor's car, Bessie. (TV: The Dæmons)

In custody Edit

Prior to his trial, the Master was sent to Stangmoor Prison. During his captivity, an army of hypnotised salespeople stormed the facility and attempted to rescue him, but the ploy failed and the Master was sent to another secure holding facility. Meanwhile, the Doctor and Jo were trapped in an extra-universal prison by the Freedom Corporation, so the Brigadier was forced to strike a deal with the Master to save them. But the Master double-crossed him and used time travel technology to regress the Earth backwards in time. However, with help from the Time Lords, the Doctor was freed and was able to stop the Master's plan and restore everything to normal. (PROSE: Freedom)

At his trial, the government used the Master as a scapegoat for all the alien attacks which had recently occurred. (PROSE: Who Killed Kennedy)

The Master was held at Aylesbury Grange Detention Centre. Demanding the Doctor visit him, he engaged the Doctor in conversation, insisting he had changed. However, the Doctor refused to believe him, and the Master reluctantly revealed that he had drawn the Doctor to the facility as part of an escape attempt and that the Doctor was speaking to a hologram. The Master nearly escaped but was stopped by UNIT soldiers accompanying the Doctor, who revealed he had been a hologram as well. (COMIC: The Man in the Ion Mask)

In another escape attempt, the Master created a device that switched his mind with the Doctor's. He went to the Doctor's TARDIS, where he learned that the Time Lords had made the TARDIS ineffective to the Doctor's piloting. Before returning to his own body, he asked the Brigadier to move him to a new holding facility with a good view, and also encouraged Mike Yates to ask Jo Grant out on a date. (PROSE: The Switching)

While in custody, with the Doctor on Peladon, (TV: The Curse of Peladon) the Master collaborated with UNIT to prevent an invasion by a fascist version of Earth, travelling with the Brigadier, Ian and Barbara Chesterton to the alternate universe and encountering Koschei, the alternate version of himself. Koschei was imprisoned and tortured by order of the Leader of the Republic of Great Britain. The Master killed his other self, claiming it was an act of mercy. Before he was imprisoned by UNIT again, the Master hid his TARDIS back in the church crypt in Devil's End. (PROSE: The Face of the Enemy)

The Master was imprisoned inside a castle prison on Fortress Island as the only prisoner. The Master convinced his jailer, Colonel George Trenchard, to help him steal electronic parts from HMS Seaspite, telling Trenchard that this was intended as a lure for enemy agents. With these parts, the Master instead made contact with the reptilian Sea Devils, an aquatic species similar to the land-dwelling Silurians, and planned to cause a war between humans and Sea Devils, making the Sea Devils rulers of Earth again. Because the reactivation machinery of the Sea Devils' hibernation units deteriorated during millions of years of hibernation, the Master saw it necessary to construct a sonar device to awaken the remaining reptiles.

The Master captured the Doctor and forced him to help create this device, but to prevent the device from reactivating further Sea Devil bases and stop the war, the Doctor blew up the Sea Devil base by reversing the device's polarity, creating a massive reverse feedback. The Master escaped in a hovercraft when the officer guarding him, CPO Myers, was hypnotised and framed as the Master's corpse, (TV: The Sea Devils) and the Master returned to the church crypt in Devil's End to retrieve his TARDIS. (PROSE: The Eight Doctors)

At large again Edit

Sometime after his escape, the Master took control of the Glasshouse, a facility for traumatised UNIT soldiers, taking particular control of Private Francis Cleary. He planned to use a Time Ring to have Cleary go to 1963 to prevent the assassination of John F. Kennedy, thereby altering Earth's history to make it more vulnerable to invasion. The plan failed. (PROSE: Who Killed Kennedy)

On another occasion, the Master made a deal with the Odobenidans to help them invade Earth, but accidentally trapped both them and himself in a time loop whilst undertaking some temporal mechanics on their behalf. He was trapped in the time loop beneath Greece for months. The Doctor, sent to Greece by the Time Lords to deal with the time loop, released the Master and foiled his plan. (PROSE: The Seismologist's Story)

The Master discovered the mind parasite known as the Nurazh on a desolate planet. Weakened, the creature failed to take control of him, and begged him to take it off the planet. The Master agreed, taking it to the UNIT hospital Kenstone Hall, where he planned to have it take control of the invalids, healing their injuries in the process, in order to give him an army of brainwashed slaves. The Nurazh, secretly planning to devour the Earth, eventually turned on the Master, who was last seen ducking into his TARDIS after releasing Jo Grant from the Nurazh' s control. (PROSE: The Touch of the Nurazh)

After being double-crossed by the Voords, (PROSE: The Quantum Archangel) the Master posed as "Professor Carl Thascalos" and constructed a machine known as TOMTIT at Cambridge's Newton Institute to summon the ancient chronovore Kronos, whom he wished to control. He hypnotised the institute's director, Dr Charles Percival, but accidentally killed him by releasing Kronos from the Crystal of Kronos. The Master summoned the Atlantean priest Krasis for instructions on how to control Kronos while meddling with the flow of time to obstruct the Doctor from getting in his way.

After knocking out Sergeant Benton, the Master retreated to his TARDIS, but the Doctor tried to trap him in a time lock using his own TARDIS, accidentally creating a space loop when both TARDISes were materialised within the other. When the TARDISes were separated during their negotiations, the Master ejected the Doctor into space, but the Doctor survived by using the telepathic circuit of his TARDIS to help Jo return him to safety.

The Master travelled to ancient Atlantis and failed to hypnotise King Dalios, who easily resisted his influence. Confronting the Doctor there, the Master tried to manipulate Queen Galleia into betraying her husband, since she had taken a romantic liking in his charm compared to Dalios' dull personality. Galleia, however, was enraged when the Master caused Dalios to die in the coup they staged in Atlantis. Before he was arrested, the Master commanded Krasis to use the Crystal of Kronos housed in Atlantis and brought forth Kronos, who destroyed the entire civilisation.

Fleeing Atlantis with Jo as his hostage, and with Kronos under his control, the Master was in a position to cast destruction unto the entire cosmos, however, the Doctor threatened to time ram the Master's TARDIS with his own, which would take everyone's lives in the process if he did not give up his plans for chaos. The Master did not believe the Doctor would earnestly carry out his warning because he knew endangering Jo's life was not an option for him. In response to the Doctor's hesitation, Jo tried to complete the time ram before the Master could release Kronos again. Instead, Kronos spared everyone from death, and captured the Master for the crime of trying to control it, but allowed him to go free at the request of the Doctor. (TV: The Time Monster)

The Master set up a talent show called Make a Star, based on the anagram "AKA MASTER", which he used to disrupt the timeline by making the contestants cover songs that weren't yet written. He intended to use the relatively minor disruption caused to allow him to take control of Earth, but this plan was foiled by the Third Doctor and Jo Grant. (PROSE: Hidden Talent)

Following the Doctor's TARDIS to 25 December 2006, the Master learnt that the Earth was being invaded by the Sycorax, whom he intended to ally with so he could enslave the planet himself. Arriving at 48 Bucknall House at the Powell Estate, the Master was trapped by tinsel controlled by the Roboforms after stepping out of his TARDIS. After an hour listening to The Twelve Days of Christmas played by a broken snowman ornament, the Master was found by the Doctor, Jo, Yates and Jackie Tyler. Deeming that the Master had suffered enough, the Doctor set him free to take his leave in his TARDIS. (PROSE: The Christmas Inversion)

Distancing himself from UNIT Edit

The Master travelled to the Land of Fiction, where he intended to steal an advanced piece of technology from the Land, and defeated Professor Moriarty, (COMIC: Character Assassin) and became involved in "a galactic fracas" relating to "a number of large tortoises". The Doctor and Jo put a stop to this scheme. (AUDIO: The Last Fairy Tale) He attended Bonjaxx's birthday party at Maruthea. When a fight broke out, the Master was seen crouching to avoid the confrontation, evidently annoyed. (COMIC: Party Animals)

The Master used time-displaced Scottish warriors to seize a nuclear submarine and threaten Britain with obliteration if he wasn't given the Doctor's TARDIS; he ended up temporarily trapped in the 18th century. (COMIC: The Glen of Sleeping)

For a short while, the Master adopted the identity of "Duke Dominus", a gangster on early 20th century Earth, but his plan was foiled by the Fourth Doctor without either realising the others' involvement. (PROSE: The Duke of Dominoes)

The Master travelled to a Sontaran-occupied planet and convinced several of the locals that he was a deity. This would form a new sect of proud, beard-toting column-worshipping Sontarans, which would decades later lead to the destruction of the entire planet by Sontaran command. The Master left decades before this, delighted simply by the idea of the chaos he had created. (COMIC: The Judas Goatee)

Final exploits Edit

This section's awfully stubby Information from The One Second Hour needs to be added

The Master planned to release a fog in Tadcaster by using Sarkan mist-flowers to generate a fog that would engulf the Earth in a dense fog. Attempting to catch up with the Master, the Doctor commandeered a pier train that crashed into the Master and the mist-flowers, sending all of them into the ocean, where the flowers were destroyed and the Master disappeared. (COMIC: Fogbound)

Reappearing again, the Master took control of the Brigadier's mind and instructed him to kill the Doctor. However, the Brigadier attacked the Master, but he escaped, restoring the Brigadier to his senses. (PROSE: Smash Hit)

Having had enough of Earth, and having other plans to set in motion on Skaro, the Master employed the assistance of a being called Verdigris to impersonate him. (PROSE: Verdigris) On Skaro, the Master forged an alliance with the Daleks, acting as their agent to provoke warfare between the Earth Empire and the Draconian Empire in the 26th century. To achieve this, he employed a force of Ogrons who, through the use of hypnosound, made themselves appear human or Draconian, thus provoking the other side. When the Doctor revealed the true perpetrators, the plot was abandoned. (TV: Frontier in Space)

Meeting his end Edit

According to one account, some time after his alliance with the Daleks against the Draconians fell through, the Master used files he had uncovered from the Daleks to go undercover on Earth following the 22nd century Dalek invasion, seeking a matter transmuter the Daleks had built during the course of the invasion in their base DA-17. As his scheme took a while to mature, the Master decided to stave off boredom by meddling in local politics under the name of "Estro". Making himself the trusted advisor of Lord Haldoran, he schemed to create a war between Haldoran's forces and Lord London's.

As he finally prepared to seize the matter transmuter, he found that Susan Foreman, who had been living on Earth for thirty years with her husband David Campbell, had gotten there before him and was trying to destroy the device. Though he failed to recognise her as the Doctor's granddaughter, he got the impression that she was at least one of the Doctor's former companions, and took her with him as a hostage back to his TARDIS. During a confrontation with the Eighth Doctor, who was foiling the Daleks' plan and discovered the Master's presence in the process, he shot at the Doctor, but instead hit David, who threw himself in front of the Doctor to save him and died.

The matter transmuter still in hand, the Master fled in his TARDIS, and took Susan with him, still unaware of her Gallifreyan heritage. As his TARDIS materialised on Tersurus, Susan awoke from her shock-induced torpor and, with her mental abilities amplified by telepathic circuits of the Master's TARDIS, used her telepathy to focus all of her hatred and grief into a force that "burned away" at the Master's mind, chipping away at his personality until she revealed the "utterly unrepentant, inhuman core of it". Though reduced to a "trembling creature" by the experience, the Master did not lose his force of will nor his hatred for the Doctor, focusing the former on the latter and thereby hanging on to consciousness and a semblance of sanity.

Believing she had weakened him into harmlessness, Susan forced the Master out onto Tersurus's surface, planning to strand him there. Having seized the Tissue Compression Eliminator, she planned to use it to destroy the Daleks' matter transmuter. The Master furiously clung to the device, refusing to let go even when she warned him that she would shoot it whether or not he was still holding it, and ended up doing so. The blast that resulted from the TCE hitting the matter transmuter nearly killed the Master and left his body as deformed as his mind. Susan knew that the matter transmuter's nature, combined with the Master's weakened mind, left him in no state to regenerate. Believing him dead, Susan departed in his TARDIS.

Susan's use of his TARDIS, however, alerted the Time Lords to the Master's presence on Tersurus, as Susan, in fear that the Master had programmed them to kill anyone other than him trying to pilot the ship, had switched off the TT capsule's defence systems. Investigating the materialisation of an unauthorised TARDIS, the Time Lord Chancellor Goth arrived on Tersurus, where he found the Master in a wasted condition — that of a decaying animated corpse. The Master sensed that Goth wished for power and offered it to him, whilst Goth, seeing the Master as a dying "creature", thought he could control the Master for his own means. (PROSE: Legacy of the Daleks)

According to another account, the Master decided to return to Earth after the affair with the Daleks and the Draconians and detected a massive discharge of temporal energy. He watched as the Twelfth Doctor's TARDIS exploded (COMIC: Doorway to Hell) in 1972 after it was overloaded by its efforts to rewrite a mutated plague. (COMIC: The Pestilent Heart) The Master wrongly speculated this was the cause of the Doctor's third regeneration. (COMIC: Doorway to Hell) When the Doctor moved in with Jess Collins' family in Brixton and brought the TARDIS into the back garden to repair itself, (COMIC: Moving In) the Master plotted to use the artron energy given off by the regenerating TARDIS that now lay in the bodies of the Collins family to create a portal to a time locked dimension he learnt about in the Dalek databanks. When the TARDIS had healed in 1973, the Master utilised the efforts of Katya Dabrowski to bring the Collins family to an apartment in central London, while creating a diversion for the Twelfth Doctor in Barking with glass mosquito creatures. Warning the Collins family that the Doctor was a dangerous and deceitful alien, the Master tricked them into being scanned for damage, when he actually used them to create a portal to the dimension which they were also sent through. The Master also stole the Doctor's TARDIS and had the Doctor escorted from the Collins family's home to the Master's apartment. The Master linked the Doctor's TARDIS to his own, in order to aid the Doctor through the time lock, so he could be reunited with the Collins family. The Master had Katya accompany the Doctor there.

Travelling to the locked dimension, the Master met Kiadine, a being who once split the chronon. The Time Lords locked him away for this, and he hated them for it ever since. He gave the Master his powers so that he would conquer Gallifrey on his behalf. His exposure to the chronon storm gave him god-like powers, and he began to fight with the Doctor for mastery of them. The Master fired one final attack as the Doctor stood arm in arm with the Collins family, and found that his attack had been repelled back at him with the same artron energy in the bodies of the Collins family that had brought the Master to the dimension. Though battered from the attack, the Master was able to escape in his TARDIS and regenerated while declaring his intent of revenge on the Doctor. (COMIC: Doorway to Hell) Shortly after his regeneration, the new Master visited the Scoundrels Club to recover. (PROSE: Dismemberment)

A body in decay Edit

All accounts concur that, having regenerated into his thirteenth incarnation at an accelerated rate due to living a life "more rackety than the Doctor's", (PROSE: A Brief History of Time Lords) that had constant pressure and danger, in addition to using some incarnations as disguises, (PROSE: Doctor Who and the Deadly Assassin) the Master found himself trapped as a wraith-like living cadaver, "horribly emaciated", for whom "no regeneration was possible". (TV: The Deadly Assassin) However, accounts differed on whether this rotting, lich-like Master was a degenerate version of the "UNIT enemy" Master, (PROSE: War of the Daleks) the eventual fate of a succeeding regeneration, (COMIC: Doorway to Hell) or the result of the actual Thirteenth Master's wrong-headed attempt to regenerate "one time too many", as the Thirteenth Doctor believed. (PROSE: The Doctor vs the Master)

At war with his future Edit

The Master arrived on a Time Lord base on Tersurus with the intention of infiltrating their database. There, he encountered a future version of himself, who burned his body, leaving him a fraction above death. The future Master then signaled Gallifrey for Goth to arrive. Before Goth could arrive, the Cult of the Heretic switched the Master's mind with that of his future self. (AUDIO: The Two Masters) While he remembered being in great pain, the process left gaps in the Master's memory. He returned to a prison in the south of England, where a former incarnation had lured a Carmentine Mind Leach. He set up the Dominus Institute in order to lure the Doctor to him, planning to absorb his intellect. The Sixth Doctor made a deal with the mind leech, one which had the leech only take the Doctor's short term memory. This was enough to sustain the Master, but ruined his overall plans. The Master fled from the prison in his TARDIS. (AUDIO: Vampire of the Mind)

Regaining his memory of what had happened to him, the "Decayed" Master hired the Transhuman Sisters of the Unholy Protocol and the Dragonhunters to kill his future self. The act of having a Time Lord inhabiting the body of his past self led to the universe beginning to break down. Realising this, the Seventh Doctor encountered both of the Masters and and persuaded them to return to their rightful bodies. Abandoning the Doctor on a ship that was set to crash into a hypergate, the two Masters stole his TARDIS and helped them get back into the right bodies.

The two Masters then returned to the Cult's headquarters and killed all of the members. They then plotted to use the anomaly cage to remake reality in their image, but were stopped by the Doctor, who had escaped the crash in the Master's TARDIS. The Doctor then used the cage to restore the universe, leaving it practically unchanged by its regeneration, apart from erasing the Masters' memories of the events and sending them back to their proper points in history. After this, history was allowed to run its normal course, and Goth collected the "Decayed" Master and took him to Gallifrey. (AUDIO: The Two Masters)

Revenge on Gallifrey Edit

Whilst on Gallifrey, the Master made Goth, in line for the position of Lord President of the High Council of Time Lords, into his slave, continuing to promise him power until Goth could no longer fight his mental dominance. The Master also took over the Matrix, and realised that the Eye of Harmony resided beneath the Panopticon. He believed he could use the Sash of Rassilon to protect himself from the raw power of the Eye and channel that energy to renew himself.

With a telepathic summons and a vision of the future created by the Matrix, the Master lured the Fourth Doctor to Gallifrey, seemingly to prevent the murder of the then-serving Lord President. The Doctor failed and ended up on trial for the President's murder.

After Goth died, the Doctor defeated the Master in physical combat and, as a result, the Master fell into a crevice created by a localised earthquake. He gained access to his TARDIS in the confusion and escaped, (TV: The Deadly Assassin) having been able to convert the energy from the Eye of Harmony and partially heal himself. (AUDIO: Trail of the White Worm)

The Master followed the Doctor's TARDIS from Gallifrey, but was knocked off course passing through the transduction barrier and landed in London during the 1890s. (AUDIO: Masterpiece) He asked the locals if he could speak to someone in authority, and Inspector Quick was the first on the scene. The Master wasted no time in hypnotising Quick for his goals, (AUDIO: The Museum of Curiosities) giving him several tasks to carry out on his behalf. (AUDIO: Jago & Son)

The Master walked the streets of London, concealing himself with a mask and walking with a cane. He spoke to Maurice Ravel, interested in a watch he carried with the Prydonian Seal on it. The Master later learned that Jago and Litefoot were the Doctor's contacts in the time period, and intended to visit them. (AUDIO: Maurice) The Master had Quick bring him a sample of Jago and Litefoot's DNA, planning to poison them so that they would summon the Doctor to help them. (AUDIO: The Woman in White)

As he became more frail, the Master planned to use the Doctor's artron energy in order to heal his form. He travelled to the Red Tavern and spoke to Ellie Higson, hypnotising her so that he could learn of Jago and Litefoot, and reverted her metabolism to its natural state, causing her to lose control of her vampiric hunger. Jago and Litefoot learned of the location of the Master's lair with the help of Madame Sosostris and encountered the Master there. Sosostris' assistant revealed himself to be the Sixth Doctor. The Master activated a machine to drain the life energy of Jago and Litefoot, before absorbing the Doctor's artron energy. The Doctor reversed the flow of the machine and the Master's life began to be drained. After the Doctor smashed his equipment, the Master slipped into his TARDIS and escaped. (AUDIO: Masterpiece)

Surviving in the universe Edit

With his TARDIS still in the form of a clock, the Master attempted to steal Iris Wildthyme's body, (PROSE: The Scarlet Shadow) and was captured by the Sild. (PROSE: Harvest of Time)

Still looking a little "putrescent", (COMIC: The Abominable Showmen) the "Decayed" Master was greeted by a female incarnation of himself known as "Missy", who had developed a plan to form a band to hypnotise viewers of The Battle of the Bands Beyond the Stars. His next incarnation, an incarnation possessing the body of a man named Bruce and an incarnation going by the name "Saxon" all joined in the plan, and the team spent "decades" practicing. (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 control of her device, believing that he alone could hold the universe in his grasp. The "Decayed" Master joined in the struggle, declaring that his future selves were idiots. The five were quickly disqualified, seemingly destroying them. (COMIC: The Five Masters)

First meeting with River Song Edit

Posing as a Sun God, the Master forced the Therians to build a solar relais to prevent night from falling on Jaska Minor. After finding their worship boring, he ordered them to build him a tomb and seal him in it, as he entered a stasis chamber to await the Doctor. As he slept in the chamber, his tomb was removed from Jaska Minor and placed inside a museum on Jaska Major, where the Master was awakened by River Song and Luke Sullieman. Realising what had happened, the Master persuaded River to return him to Jaska Minor and retrieve his TARDIS in exchange for a chance to investigate the local ziqqurat.

Once they arrived on Jaska Minor, the Master began killing River's companions in order to both distract the Therians and pass the booby traps in the ziqqurat. Once the solar relais was deactivated, allowing night to fall, the Master still needed his solar capacitor to power his TARDIS, so agreed to help River escape from the planet in exchange for her help. However, River left the capacitor with the Therians, allowing them to revert their evolution and become people again, and abandoned the Master to their mercy. (AUDIO: Animal Instinct)

Fighting the Fourth Doctor Edit

The Master plotted to capture the Z-battery that the Third Doctor left on Earth to repair his TARDIS during his exile. The Master's plan was to use the Z-radiation within the battery, combined with the O-radiation which permeated Oseidon, to create powerful ZO-radiation which the Master could use to renew himself. For his plot, the Master entered into an alliance with the Kraals, and created two robot duplicates; one to pose as Kraal Chief Scientist Tyngworg, (AUDIO: The Oseidon Adventure) and a second to search for genetically engineered alien worm in Derbyshire. In Derbyshire, he spent his time living underneath Hugh Spindleton's house. He offered Leela to the worm, but the worm didn't want to eat her. Knowing that the Doctor was near, he advanced his plans and wanted to capture him. He mused why the worm wanted the Doctor. He activated the worm by generating a lightning storm. (AUDIO: Trail of the White Worm)

The Master wanted to kill the Doctor with his TCE. He was arrested by Grimnal, but rescued by Leela, and they both went to Oseidon. The duplicate that stayed on Oseidon destroyed the one from Earth. The Doctor defeated the Master by using a Master android duplicate that he had constructed to kidnap the real Master, and take him away in his own TARDIS before his plan could be fulfilled. (AUDIO: The Oseidon Adventure)

The Master then posed as Inspector Efendi of the Intergalactic insurance agency so that he could find spaceships full of gold bullion. He then employed the Salonu to steal this gold, which attracted the attention of the Doctor and Leela to investigate. The Master then used the telepathic abilities of the Salonu to influence Leela into thinking that she was the Master's assassin and that he was the great Xoanon who desired the death of the Doctor. The Salonu Prime, with the help of the Doctor, noticed the Master's influence and undid the conditioning. (AUDIO: The Evil One)

Shandar of the Rocket Men invited the Master on his ship the Asteroid, where the Master saw the Doctor was Shandar's prisoner. When he confronted the Doctor, the Master used his Tissue Compression Eliminator on him, and apparently killed him, but he realised he had only destroyed a duplicate. The real Doctor was in fact pretending to be Oskin, and used that guise to bring down the force field around the ship, and used K9 Mark I to stall the Master's TARDIS once it had passed the force field so that the slaves on board the Asteroid could be freed. The Master overrode K9's tampering and kidnapped Leela after she had left the Doctor. (AUDIO: Requiem for the Rocket Men)

Charming the participants' owners with fine dining, the Master became the huntmaster of the Death Match, and used Leela as his champion. The Master said all that he was doing was reviving an old Gallifreyan past-time and sent the Doctor into the Game. He then set the endgame protocols which meant every contestant had an hour to live. Kastrella worked out that his plan was to wipe out the heads of major armies using his game to do this. He indulged her in killing all her rivals. After the Doctor reversed the command Matrix, he was to be killed as part of the endgame and would only live if he killed Kastrella. (AUDIO: Death Match)

The Master attempted to rend asunder the constellation of Mandus using a segment of the Key to Time, but was defeated by the Doctor. (PROSE: Cold Fusion) On Kendrax, the Master attempted to ally himself with the Daleks and the Cybermen, but his plan was foiled by Romana II. (PROSE: Special Occasions: 1. The Not-So-Sinister Spong) He also entered a pact with the Embodiment of Gris, but found himself again bested by the Doctor. (PROSE: Cold Fusion)

Final gambits Edit

The Master was drawn to and became stranded on the planet Traken, the centre of the Traken Union, in a TARDIS configured into the sculpture-shaped Melkur. He plotted to take over the Source also located on the planet Traken, the power behind the Traken Union, and use it to restore himself. To this end, over a period of years, he won over Kassia, who later married Tremas and became a stepmother to Nyssa. His plans were thwarted by the Doctor and Adric when the Keeper of Traken summoned them, having sensed something of his machinations. With the help of Tremas and Nyssa, the Doctor removed the Master from the Source. However, with some of the Keeper's powers lingering, 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)

In Tremas' body Edit

First exploits Edit

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. His true plan was revealed however 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)

As the Fifth Doctor made his leave in the TARDIS, 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 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 Tegan and her 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)

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, first, a sword-fight and then a mental battle of wits over the command of Kamelion, the Master fled in his TARDIS. (TV: The King's Demons)

The Game of Rassilon Edit

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 and blamed him for their being there, taking the seal from him on the pretense that he would return the "stolen property" to the High Council.

The Master soon after 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, however, a group of Cybermen ambushed them, 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 his help when he was genuinely there to lend assistance. Brigadier Lethbridge-Stewart knocked him unconscious and Sarah Jane Smith and Tegan Jovanka bound him with rope. After 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)

Without a body Edit

For failing to help the Doctor in the Death Zone, the Time Lords destroyed the Master's Trakenite body, reducing him to little more than a helpless phantom as they exiled him to the depths 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)

Damaging his body Edit

This section's awfully stubby Information from A Town Called Eternity needs to be added

The Master developed a more powerful version of the Tissue Compression Eliminator and accidentally shrank himself and his lab, without the ill effect of death. Using a device to boost his telepathy, the Master 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) Horrifically burned, the Master went in search of the Fountain of Youth to restore himself. (PROSE: A Town Called Eternity)

Interfering with regeneration Edit

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 the spectrox toxaemia poisoning in the TARDIS, (TV: The Caves of Androzani) but was foiled by Nyssa. (AUDIO: Winter)

Interfering in history Edit

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)

Forging alliances Edit

This section's awfully stubby Information from The Fellowship of Quan needs to be added

The Master materialised in the Matrix and observed the Sixth 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)

The Master was greeted by a female incarnation of himself known as "Missy", who had developed a plan to form a band to hypnotise viewers of The Battle of the Bands Beyond the Stars. His previous incarnation, an incarnation possessing the body of a man known as Bruce and an incarnation who went by the name "Saxon" 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)

Haunted by the past Edit

After escaping from an unsuccessful alliance with the Krotons, the Master was attacked by the 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 son of TOMTIT, 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 Sixth 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)

Further schemes Edit

Distancing himself from the Doctor Edit

This section's awfully stubby Information from Winning needs to be added

At some point, the Master discovered the Parallel Sect, where he possessed the body of Keith Potter, wanting to dominate the dimensional nexus. He found the Valeyard, and encountered the Sixth 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)

Alliance with Adam Mitchell Edit

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)

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 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, still pleased by his role within all the chaos, teleported away. (COMIC: Endgame)

Deadlier campaigns Edit

The Cheetah World gambit Edit

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 Edit

The Master was seen multiple times after somehow escaping the Cheetah World, still in Tremas's body and infected by the Cheetah Virus. (PROSE: Stop the Pigeon, Prime Time) However, 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 even more contradictory accounts, the Master was either taken to Skaro for trial and execution in his stolen Trakenite body, and still infected by the virus, (PROSE: The Eight Doctors) or, no longer infected by the virus, lost Tremas's body and reverted to his previous cadaverous form. (AUDIO: Dust Breeding)

Tremas persists Edit

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 battle between the two Time Lords. The Master escaped in the confusion, leaving the Doctor to pick up the pieces. (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)

No longer affected by the Cheetah virus, and wanting to find a way to survive beyond his final regeneration, the Master tried to steal the body of a mouse-turned-boy named Callum, but his plan was foiled by the Doctor. (PROSE: Omegamorphosis)

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)

On a desert planet on the fringes of Mutter's Spiral, the Master 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)

Finding a new regenerative cycle in the past Edit

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. Following the regeneration, he was able to make his escape, summoning his TARDIS using a Stattenheim remote control built from Tzun technology. After leaving a booby-trap for the Doctor in a nuclear warhead, the Master fled (PROSE: First Frontier) to the Scoundrels Club to recover from his regeneration. (PROSE: Dismemberment)

Later, the Master laid a trap for the Doctor in one of the Doctor's homes using a device which would release the energy from a time fissure once the Doctor's TARDIS materialised, destroying it. The plan failed when Sarah Jane Smith, Mike Yates and K9 Mark III destroyed the device, causing the Master to flee. (PROSE: Housewarming)

The Master later obtained the Loom of Rassilon's Mouse in order to make himself a sturdier and indestructible body. However, his plan failed when a Fortean Flicker caused Bernice Summerfield's wedding to occur in the same place, exposing his scheme to her guests, with the Doctor being amongst them. However, the Master managed to escape by hypnotising Kitai into posing as a decoy. (PROSE: Happy Endings)

Like all of his other attempts at extending his life, the Master's Tzun-made body eventually reverted back to a decayed husk. (AUDIO: Planet of Dust)

Reduced to an old body Edit

In another account, the Master, still in Tremas's body, learned of a device known as the Warp Core, a sentient powerhouse of mental energy designed as a weapon to safeguard the planet Duchamp 331. He tracked the Warp Core to Earth, intending to use it to power his TARDIS. Unprepared for its power and underestimating its outside awareness, he was attacked by the Warp Core, which stripped his Trakenite body from him and reduced him to his previous decaying form. Afterwards, 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.

There, 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 was destroyed, the Master was flung through time and space. (AUDIO: Dust Breeding)

The Doctor later 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)

The Master on trial Edit

In his "final" incarnation, (TV: Doctor Who) the Master was known by the Seventh Doctor to have once more "extended his life" by adding alien genes to his biomass, becoming a man with "saturnine features". (PROSE: The Novel of the Film) The Master eventually arrived in the Valley of the Kings in Egypt and was captured to be placed on trial (AUDIO: Mastermind) by a Dalek scouting party. (PROSE: Dalek: The Astounding Untold History of the Greatest Enemies of the Universe) Another account claimed that the Master's trial by the Daleks took place immediately after his experience on the Cheetah World, with him still in his stolen Trakenite body and maddened by the cheetah virus. (PROSE: The Eight Doctors)

At any rate, the Master was indeed tried in the presence of the Dalek Emperor, for his attempts to destroy them and usurp their place as "the supreme creatures of the universe", while encased in a painful column of light which prevented him from moving; (PROSE: The Novel of the Film) it was "said" that he stayed oddly impassive as his long list of crimes was read out to him. In truth, this was all a ruse to get inside the Doctor's TARDIS and further extend his precarious existence. (TV: Doctor Who)

After he was tried and executed by the Daleks on Skaro, he made a final request: for the Seventh Doctor to transport his remains back to Gallifrey. (TV: Doctor Who) According to one account, he made this request via telepathic contact with the Seventh Doctor, even as he was about to be discorporated, and the Daleks never knew of his demands, which the Doctor fulfilled covertly by sneaking into the Dalek bastion. (PROSE: The Novel of the Film) According to other accounts, it was as part of a Time Lord-Dalek treaty (PROSE: Lungbarrow) called the "Act of Master Restitution" (PROSE: A Brief History of Time Lords, Meet the Doctor) that the Doctor was able to safely journey to and from Skaro to retrieve the Master's remains. (TV: Doctor Who)

Fighting the Eighth Doctor Edit

The Deathworm Morphant Edit

Unbeknownst to the Doctor, the Master's essence survived his physical death in a fluid-like form resembling a snake. (TV: Doctor Who) Although the Eighth Doctor mentioned that he could do the same as the Master, but only when he died, (TV: Doctor Who) other accounts stated that this ability to survive as a Deathworm Morphant was not inherent in Time Lords, but the product of the Master having purposefully ingested a Morphant in advance, already intending to then have his body destroyed by the Daleks so he could use the Morphant's form to find a new and better one. (PROSE: The Eight Doctors, AUDIO: Mastermind) The Master's survival broke the peace treaty President Romana started under the Act of Master Restitution and was one of the causes for the Last Great Time War. (PROSE; A Brief History of Time Lords)

The Doctor stored the Master's ashes in a casket and set his TARDIS on course for Gallifrey. However, en route, the Master's consciousness escaped from the casket and interfered with the TARDIS, causing a timing malfunction that resulted in an emergency landing in San Francisco during the final days of 1999. While the Doctor lay wounded after being caught in the crossfire of a gang war and was picked up by an ambulance, the Master exited the TARDIS via its keyhole and, (TV: Doctor Who) deciding that the Doctor was too injured, and the nearby boy, Chang Lee, too young, (PROSE: The Novel of the Film) he hid inside a bag belonging to the ambulance driver, Bruce. (TV: Doctor Who)

After Bruce had gone to home and bed, the Master forced his way into Bruce's body through his mouth, killing him and taking over his body. The next morning, the Master awoke, now inhabiting Bruce's body, but realised that the American's body had started decaying and would not last long and launched his scheme to steal the Doctor's remaining regenerations, with his first act being the murder of Bruce's wife, (TV: Doctor Who) and then used Bruce's memories to track the Doctor to Walker General Hospital. (PROSE: The Novel of the Film)

Stealing Bruce's body Edit

Learning from Bruce's colleagues that the Doctor had died on the operating table and that his body had apparently been stolen, the Master was also informed by Nurse Curtis that the young gang member who had been present when the Doctor was shot, Chang Lee, had also stolen the Doctor's possessions, including the TARDIS key. (TV: Doctor Who) Heading to the TARDIS, the Master found Lee already inside, (PROSE: The Novel of the Film) and regaled him with stories of the Doctor's supposed villainy, claiming that the Doctor had stolen his lives and home, and was also Genghis Khan. With Lee's help, the Master was able to open the Eye of Harmony, and discovered that the Doctor had regenerated into a new body, and that the Doctor was apparently half-human. (TV: Doctor Who)

Stealing Bruce's ambulance by murdering his paramedic partner, the Master and Lee answered Dr. Grace Holloway's request for an ambulance to collect the Doctor, (PROSE: The Novel of the Film) and agreed to take them to Professor Wagg's atomic clock at the Institute for Technological Advancement and Research and repair the timing malfunction the Master caused with the clock's beryllium chip, when he was really planning to bring the Doctor back to the TARDIS. Realising the Master's true identity, the Doctor and Grace escaped, but before they could do so, the Master secretly possessed Grace's mind. When the Doctor got back to the TARDIS to fix the timing malfunction, the Master had Grace knock the Doctor out and put him in restraints.

Having donned more traditional Gallifreyan robes, the Master boasted his plans to the restrained Doctor, accidentally letting it slip that he had lost his lives trying to destroy the Doctor, exposing his earlier lies to Lee. After killing Lee for refusing to follow his orders, the Master forcibly opened the Eye using Grace's retina so that he could steal the Doctor's regenerations. Although the Master was able to initiate the transfer process that would give him access to the Doctor's remaining regenerations, Grace was able to prevent this by rerouting the TARDIS' power and sending the ship into a temporal orbit. Grace released the Doctor from his restraints, but the Master threw Grace off of a balcony inside the Cloister Room, killing her. With the Master's body dying as the Doctor's regenerations were returned to him, the two Time Lords fought near the Eye of Harmony, culminating in the Master falling into it when he leapt at the Doctor and misjudged the angle. (TV: Doctor Who)

There were many rumours on Gallifrey concerning what happened to the Master after he was sucked into the Eye of Harmony in the Doctor's TARDIS. Some rumours stated that he was saved from inside the Time Vortex by the mythical Esterath; others said that he remained trapped in the TARDIS with his mind transferred into an android body to become the Doctor's "companion or pet"; still others claimed that this was the death that he would later be resurrected from by the Time Lords to fight in the Last Great Time War. (PROSE: A Brief History of Time Lords) In one account from the Time War, the Master's resurrection by the Time Lords damaged the Doctor's TARDIS's control console, with the lingering trauma of the Master's extraction from the TARDIS causing it to adopt a new appearance shortly after the Doctor regenerated at the conclusion of the Time War. (PROSE: Doctor Who and the Time War)

Escape into the Vortex Edit

As the Eye of Harmony tried to break him down into pure energy, the Master managed to ride the energy into a spare room, which the Doctor's TARDIS then ejected into the Time Vortex to protect the Doctor. The Master would remain stranded in the vortex for hundreds of years, rooting through the Doctor's possessions in search of something to help him escape.

Inspired by a VHS he found in the TARDIS' spare room, the Master brainwashed and disguised "Alison", a child of the Vormatoda, as his daughter. He ended up on a vortex ship posing as "Daniel", where he encountered River Song. After his true identity was discovered and his plan failed, the Master managed to escape the vortex with Kaliopi Mileska in a stasis pod. (AUDIO: The Lifeboat and the Deathboat)

Still in Bruce's body, (COMIC: The Abominable Showmen) the Master was greeted by a female incarnation of himself known as "Missy", who had developed a plan to form a band to hypnotise viewers of The Battle of the Bands Beyond the Stars. His decaying thirteenth incarnation, an incarnation possessing the body of Tremas and an incarnation going by the name "Saxon" 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 control of her device, believing that he alone could hold the universe in his grasp. The "Decayed" Master joined in the struggle, followed rapidly by the "Deathworm" Master, and the group soon became involved in a full on brawl. The five were quickly disqualified, seemingly destroying them. (COMIC: The Five Masters)

The Master eventually found himself on Kolstan, where he met Artron, and posed as an assistant sent by the Time Lords. When the Eighth Doctor arrived in the future Master's TARDIS, the Master inflicted a fatal wound on the Doctor and used this to force Artron to operate a machine that would transfer the energy of the native Kolstani into him. However, Artron was able to adjust the machine so that he would absorb the power of the Kolstani, although this unintentionally turned them into the Ravenous. When Artron absorbed the power of the Kolstani and disappeared with the Doctor, the Master used his future TARDIS to escape to the Time Lord station that all his incarnations used as a base.

Meeting with the "War" Master and Missy, the "Bruce" Master worked with them to stop the Ravenous's alliance with the Eleven, the "Bruce" Master acting as the group's negotiator due to the Ravenous' inability to eat him in his current state. After undoing the Eleven's scheme, the "Bruce" Master had his memory of the events that had occurred wiped and was thrown back into the Vortex by his future selves to preserve their timeline, (AUDIO: Day of the Master) and was eventually drawn back into the Eye of Harmony. (AUDIO: Planet of Dust)

An echo in the Eye of Harmony Edit

While his essence was left wandering the Time Vortex, (COMIC: The Glorious Dead) an "echo" of the Master remained imprisoned inside the Doctor's TARDIS. In the singularity of the Eye of Harmony, the Master commanded infinite power, but could only wield it from within the confines of the Eye. (PROSE: The Gallifrey Chronicles)

Shortly after his defeat, the Master laid a final trap for the Doctor, leaving a crystalline structure on the Eye that would give the Doctor amnesia. However, the Doctor was subconsciously guided by Rassilon to recover his memories by visiting his previous seven selves. (PROSE: The Eight Doctors) Whilst exploring the Eighth Doctor's TARDIS, River Song thought she heard an American screaming from within the walls. (GAME: The Eternity Clock)

During his imprisonment, the Doctor came to speak to the Master where he dwelled in a room with his face on a screen. The Master spoke to the Doctor in the room on several occasions, telling him that he was an "old friend". After the defeat of the Council of Eight, the Doctor spoke to him about the death of Miranda Dawkins and if it was worth the cost of him saving the universe. (PROSE: Sometime Never...)

The Master later appeared to the Doctor within a mirror in the TARDIS, where he asked the Doctor what was going on inside his head. The Doctor was unable to answer the question before the image in the mirror returned to that of the Doctor's reflection. (PROSE: The Deadstone Memorial)

The Master had a longer conversation with the Doctor from within the Eye of Harmony. The Master showed the Doctor a vision of Marnal's investigation of the Shoal. When the Doctor pressed him about what happened to Gallifrey, the Master teased him with offers to bring it back and to return his memories. The Master then became angry over the circumstances of his imprisonment. He threatened to use all of his power to detonate a fusion device and have his revenge. The Doctor sealed up the Eye of Harmony before he had the chance to carry out his plan. (PROSE: The Gallifrey Chronicles)

During the War in Heaven, Father Kreiner killed and decapitated either the original Master or a clone created as part of the Time Lords' War-time hatchling projects. (PROSE: Interference - Book One)

Beyond the Eye of Harmony Edit

According to one account, while still in the form of the snake-like Morphant, the Master visited the Scoundrels Club, as he always did when having gained a new physical form, and he sat in his favourite chair, taking notice how his snake form went unnoticed. (PROSE: Dismemberment)

Fight for the Glory Edit

After the Master passed through the Eye of Harmony, his essence was left wandering the Time Vortex. Nearing his ultimate destruction, he was rescued from the Vortex by a being named Esterath, the controller of the Glory, the focal point of the Omniverse. The Master was told that it was time for the Glory to gain another controller, but the power had to be fought for. The Master assumed that the battle would be between himself and the Doctor.

After gliding over the many realities throughout the Omniversal Spectrum for what he described as seeming like "centuries", the Master was resurrected into the body of a recently deceased vagrant on the streets of 2001 Brixton. Some weeks afterwards, due to a symbiotic link he had formed with the Doctor's TARDIS when it consumed part of his essence after he passed through the Eye of Harmony, the Master was transported onto the Moon during one of the Doctor's adventures. The symbiotic link between the Doctor's TARDIS and the Master had also given the latter the ability to influence the flight of the TARDIS, which he used to send the craft to times and places which would weaken the Doctor's self-belief and confidence. The Master subsequently used this link to trail the Doctor for some time without his enemy suspecting. (COMIC: The Glorious Dead)

He was present in London during the crisis resulting from Grace Holloway's attempt to merge human and Time Lord DNA but was using the alien DNA of a Morphant by mistake. He killed Duncan, an MI6 agent, with his TCE. (COMIC: The Fallen)

The Master later made contact with Sato Katsura, a Japanese samurai unwillingly rendered immortal as a result of his involvement in the Doctor's adventures. The embittered warrior became the Master's follower. At his behest, Sato adopted the identity of "Cardinal Morningstar" and became the leader of the Church of the Glorious Dead, instigator of a holy war that altered the history of Earth, a planet now renamed "Dhakan". After revealing his plot to the Doctor, the Master won a sword fight with the Doctor by stabbing him, but then learned that the true battle for the Glory was between Sato and the Doctor's companion, the Cyberman Kroton, of which Kroton was the victor. Amongst his first acts as the controller of the Glory were to cleanse Earth's history and the TARDIS of the Master's influence. Kroton sent the Master away to parts unknown, who declared he would survive and return. (COMIC: The Glorious Dead)

Edward Grainger's dreams Edit

Trapped in the Eye of Harmony, the Master eventually escaped by influencing the dreams of Edward Grainger to unravel the Doctor's timeline, by killing Edward Grainger whilst he was an infant in 1906. (PROSE: Forgotten) Though his Morphant form had sublimated to a gaseous state, the Master was still capable of using its powers to possess new bodies. (AUDIO: Mastermind) However, while in the body of Sir George Steer, he was stopped by an older Edward Grainger from 2006 and Violet after being hit with a rolling pin and being removed from George. (PROSE: Prologue) The Master then managed to evade the Doctor's detection, and possessed the body of a human named Richard. (PROSE: Forgotten)

After possessing Richard, the Master killed Violet out of revenge. However, the Master discovered his possession had caused the host body to decay at an accelerated rate, so he was forced to steal more bodies to prolong his survival. Realising that the First World War was rapidly approaching, the Master decided to migrate to America to avoid the conflict and boarded a ship to go there in 1912. Ironically, he had boarded the RMS Titanic, unaware of its eventual fate, and escaped in a lifeboat when it sank.

Arriving in New York City, the Master took possession of a member of the Hudson Dusters, quickly becoming the leader of the gang and calling himself "Don Maestro". After twenty years of living in his current body, he occupied the body of his host's son, Michael, and moved to Las Vegas where he owned a casino. He accumulated money to fund experiments towards the elongation of the lifespan of his host body. Fearing the eventual decay of his body, the Master used his money to buy a penthouse to isolate himself from infection. After years living in isolation, his host's son confronted him with the knowledge that he had possessed both his father and his grandfather in some way. He then trapped the Master in the penthouse.

After UNIT were alerted to the presence of penthouse, they discovered the Master in a comatose state. He was imprisoned in the UNIT Vault, awakening every five years for one hour, before returning to a coma. After fifteen years living in th
