Doctor who is the master

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. 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".

However, according to another account, 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 of a forest. The Master was found by his TARDIS after it managed to resist the Time Lords attempt to reprogram it, and it helped him to attain physicality in the form of a shadowy figure in dark robes.

In an attempt to trap the Doctor and steal one of his remaining regenerations, the Master faked his own death, ensuring the Doctor would attend the funeral at the nursing home where he supposedly spent his final days. His plan was to force a regeneration out of the Doctor and steal this one life to revive himself using an arcane ritual involving twelve mirrors — but the Doctor was saved by Vislor Turlough , and the Master's plan was foiled yet again.

Instead, the Master found himself confronting mental projections of all his past regenerations. In a prowess of will that impressed even the Doctor, the Master was able to overpower the shades of his past selves and steal a bit of life energy from each of them, allowing him to regenerate back into his Trakenite body.

The Master briefly adopts the form of Howard Foster after taking control of Kamelion 's body. TV : Planet of Fire. When the Master developed a more powerful version of the Tissue Compression Eliminator, he accidentally shrank himself and his lab to the size of a shoe box, without the ill effect of death. Using a device to boost his telepathy, the Master resorted to making telepathic contact with Kamelion and possessing him from afar, using his shapeshifting body as a proxy to try to restore himself.

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.

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.

When a Kotturuh woman arrived on the planet, the Master pretended to intercede for the Mogellans' salvation, and they gave him one of the crystals as a a token of good faith. The crystal, however, revealed them that the Master was lying in order to exploit the crystals in the future, and they allowed the Kotturuh to end their lives to stop him.

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 Battle of the Bands Beyond the Stars.

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.

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.

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.

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.

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. 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. Fifth needs to be added. Infected with the Cheetah virus , the Master threatens the Doctor.

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. 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 Doctor escaped, but the Master was trapped on the dying world. The Master was seen multiple times after somehow escaping the Cheetah World, still in Tremas's body and infected by the Cheetah Virus.

The Master temporarily victorious in capturing the first seven incarnations of the Doctor. According to one account, the Master was freed from the effects of the Cheetah virus as soon as the Cheetah Planet ceased to exist. Since he "had to go somewhere" but did not call any place home , the last effects of the virus responded to his desire to travel in Time freely by depositing him inside the Doctor's TARDIS , which he hijacked by stealing the Identity Recognition Module ; he then set time coordinates and damaged the controls to prevent the Doctor from interfering, essentially shanghaiing Ace and the Doctor to an unknown destination aboard their own ship.

However, other accounts showed the Master as still having suffered from the effect of the virus even though he escaped the Planet's destruction unscathed. According to one such account, in the year , 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. 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.

According to one account, the Master became trapped on Earth without his TARDIS in the year after escaping the destruction of the Cheetah Planet by using a kitling named Shadow to transmigrate just as the planet exploded.

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

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 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 Under the alias "Mr.

Seta", the Master funded Madame Salvadori 's trip to Duchamp 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.

After it and the planet was destroyed, the Master was flung through time and space. 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.

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.

Unbeknownst to the Doctor, the Master's essence survived his physical death in a fluid-like form resembling a snake , described in some sources as bluish and translucent, TV : Doctor Who and in others as "giant" and "green".

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.

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 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.

The Master in Bruce's body. 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.

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. Stealing Bruce's ambulance by murdering his paramedic partner , the Master and Lee answered Dr. Realising the Master's true identity, the Doctor and Grace escaped, but before they could do so, the Master secretly possessed Grace's mind. 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.

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. 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.

The Master managed to capture a child of the Vormatoda. In the mean time the Vormatoda began attacking passing timeships in search of its child, leaving components which the Master could salvage. After her vortex manipulator stalled mid-transit, he rescued River Song via the tractor beam he'd acquired.

With him posing as "Daniel", she began to help him retrieving bits of wreckage from victims of the Vormatoda, including a piece of a prison ship that had been transporting psychopath Kaliopi Mileska. During Mileska's rampage, his true identity was revealed and River discovered the truth about Alison.

She managed to break Alison's brainwashing, allowing her to return to her natural form and reunite with her parent. With the Vormatoda now attacking his structure, the Master managed to escape the Vortex with Kaliopi in a stasis pod from the prison ship.

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.

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 Master eventually found himself on Kolstan , where he met Artron , and posed as an assistant sent by the Time Lords.

However, Artron was able to adjust the machine so that he would absorb the power of the Kolstani instead, although this unintentionally turned them into the Ravenous. 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 witnessed the regeneration of his future self and then had his memory of the events that had occurred wiped. He was thrown back into the Vortex by his future selves to preserve their timeline.

Having been trapped in the Vortex for what felt like "an eternity", the Master once managed to make psychic contact with Earth on Halloween. Teasing the humans about the holiday and his wishes for freedom, he vowed to be free soon. WC : Listen to the voice of your Master! He later psychically contacted Earth again near Christmas , which he noted was "halfway out of the dark". He offered whoever was listening a bargain for his freedom. He claimed he could to make her so much more than if she just helped him escape.

WC : Will you be the Master's valentine? The Master continued tempting Lila from within the vortex, visiting her in her dreams and promising her power. His efforts paid off and he was freed, killing Lila's colleague Eddi Bhole in the process. He later killed Magnus Drake , stole his identity and took over his company, appointing Lila as the lead scientist.

The Master and Lila landed in the slums, and after some encounters with the local gangs, managed to escape to a railway. The Master and Vienna fought, and he was knocked down by her and was thought to be dead, though he actually survived. The Master and Lila formed an alliance with Vienna, and fought off the invasion. He was later sucked back into the Time Vortex alongside the Dalek Saucer he was in. The Master was eventually drawn back into the Eye of Harmony. 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.

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.

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. The Doctor was unable to answer the question before the image in the mirror returned to that of the Doctor's reflection. 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.

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.

The Master begins to disappear after being banished by Kroton. 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 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 Master subsequently used this link to trail the Doctor for some time without his enemy suspecting. 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.

Kroton sent the Master away to parts unknown, who declared he would survive and return. 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 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 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.

However, he managed to hypnotise both of them and escape his imprisonment. As he told humans about how he brought Glox's civilisation to its ruin, he implanted into the listener a telepathic order. When the Doctor discovered his hideout, the Master ordered one of the listeners to connect telepathically to his TARDIS and become a replica of him; he then sent him out to face the security of the place and be killed in his place, while he escaped. After arriving on the planet Parrak in search of the tomb of one of Rassilon's leading engineers named Artron , the Master used his TARDIS to extract all water on the planet's surface throughout its history to use as an incentive for his workforce to keep obeying his rule.

His overall plan was to use the Tomb of Artron to revive himself, using the unlimited regenerative energy Artron had discovered on Kolstan. Nearing the end of his life and getting increasingly more desperate, the Master allied himself with the Eleven , with the intention of betraying him once the tomb was opened.

However, the Eleven had used the Master to gain access to Artron 's matrix brain, which he used to lead the Ravenous to the Doctor. Upon the Ravenous' arrival, they took great interest in the Master, believing that the flavour of all of his lives was superior to that of the Doctor's. The Ravenous feasted on him and the Master finally died, his body being left on Parrak.

However, when the Celestial Intervention Agency requested the "Bruce" Master, the "War" Master and Missy to return Artron's brain print to Parrak to help fuel the technology to grant new regenerative cycles to Time Lords, the Masters used the technology for themselves as part of the deal, and resurrected the corpse of the dead Master, giving him a new body and regeneration cycle in the process. Working against the Time Lords, the Master infiltrated a Time Lord base which contained two dimensional nodes , products of technology developed by "the Dimensioneers ", and stole them.

Attempting to control the dimensional energies of the entire universe, the Master planted one on the planet of the Tolians , allowing it to drain all the energy that was available before giving the Tolians a communicator as a way of drawing the Seventh Doctor to their planet, enabling the Master to steal the only node activator still intact from the Doctor's TARDIS.

Having successfully tricked the Doctor into restoring the Tolians' source of dimensional energy for them using his Node by manipulating him and using a form of reverse psychology , he allowed the Tolians to force him to open a dimensional rift , causing a catastrophic imbalance to the flow of dimensional energy in the process so great that it threatened the structure of reality itself.

Rescuing the Doctor and his companion Raine Creevy from becoming trapped on the other side of a dimensional rift caused by the dimensional instability, the Master stole the Doctor's node activator and sent all the alien invaders back to their own dimensions, fleeing Earth with the Doctor in his TARDIS. Revealing his true identity to the Doctor, he detailed his plan: he intended to use the activator in conjunction with the two nodes to add even more dimensional energy to the Tolians so he could use them to conquer the Earth and other planets and dimensions beyond.

However, the Doctor managed to convince the Tolian leader Arunzell that the Master would betray the Tolians, giving him the opportunity to capture the Master in return for recalling the rest of the Tolians.

However, the Master revealed that he had locked the dimensional doorway, prompting him to abandon him to Arunzell.

However, the restoration of the dimensional energies reduced Arunzell to his regular size, enabling the Master to kill him with his TCE and escape, intending to try his scheme all over again. The Master made a deal with the Cult of the Heretic to regenerate the universe using their anomaly cage. The Cult manipulated the Master into coming into contact with his thirteenth incarnation, whom he disfigured with a staser.

The paradox of having a Time Lord inhabiting the body of his past self led to the universe beginning to break down. The Cult intended to execute the "Bald" Master to make the paradox unbreakable, but the "Bald" Master was able to escape. The Cult hired the Transhuman Sisters of the Unholy Protocol and the Dragonhunters to kill the "Bald" Master and make the paradox permanent, but the Master was able to drive the assassins off with the "aid" of the Fifth Doctor.

The Seventh Doctor encountered both of the Masters 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 but were stopped by the Seventh Doctor, who made sure that the universe remained practically unchanged by its regeneration.

He then tried to use the casket to gain influence over the Eminence, and take control of its Infinite Warriors , calling them his "finite warriors". AUDIO : Time's Horizon He tried to discover why some humans were immune to the Eminence's influence, experimenting on them in an attempt to eliminate it so that the Daleks could not exploit it.

Ever the prankster, Missy fatally wounded The Master and vice versa…. Television Fox Fox. Now it seemed that he and the Doctor were the only surviving Time Lords in the universe. Again, the Doctor was able to derail his vile enterprise and the Master was thwarted. Throughout all their encounters they usually showed a respect towards each other and on the occasions when they were forced to work as a team it was clear they made terrific allies.

These two rogue Time Lords — so different but so very similar — facing the world on their terms with gusto and enormous talent, but forever ending up alone. However, on a giant colony ship caught in the event horizon of a black hole, and face to face with a new breed of Mondasian Cybermen, the Doctor and his companions discovered that loveable passenger Razor was actually the Master in disguise!

United with Missy, the two Masters joined forces to assist the rise of the Cybermen and bring the Doctor down once and for all! The Master was as nefarious as ever, but soon it became clear to him that his future self was less certain of her relationship with the Doctor.

In the greatest irony of all, Missy stabbed the Master in the back in an effort to stand with the Doctor during his final battle with the Cybermen. Knowing that he was about to die and regenerate into Missy, the Master took it upon himself to shoot Missy in the back with his laser screwdriver. Two Masters, dying by their own hand — a fitting end to two incarnations of one of the greatest villains in all of time and space….
