User:BananaClownMan/Sandbox/The Master (Harold Saxon)

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 decides not to regenerate and die to spite the Doctor.

After 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 incarnation of himself in a female body called "Missy". When the Master made to flee from the Cybermen instead of facing them with the Twelfth Doctor, he was stabbed by Missy, but was able to fatally injure her with his laser screwdriver before he regenerated from the stab wound.

Post-regeneration
After years of living as a human being under a Chameleon Arch, the Master was tempted to open the Arch after a meeting with the Tenth Doctor, Martha Jones and Jack Harkness at the end of the universe, where the Master had been working on the Utopia Project with Chantho. Arfter reverting to his true personality, the Master was shot by Chanto after he fatally wounded her, forcing him to regenerate inside the Doctor's TARDIS. (TV: Utopia)

Now in his eighteenth incarnation, (PROSE: Girl Power!) the Master left the Doctor, Martha and Jack on the planet Malcassairo with Futurekind about to burst in the laboratory door, taking the TARDIS and the Doctor's DNA template via the Doctor's hand, which Jack had taken with him to Malcassairo. (TV: Utopia) Because of the Doctor's last-minute intervention, the TARDIS would only take the Master to Earth in the 2000s, (TV: The Sound of Drums) with his first stop being to the Scoundrels Club to recover from the regeneration process. (PROSE: Dismemberment)

Life on Earth
The Master took on the alias "Harold Saxon" and set about fabricating "Saxon's" past to gain political support, making his first public appearance shortly after the downfall of Harriet Jones on Christmas Day 2006. "Harold Saxon" released his autobiography, Kiss Me, Kill Me, and, while writing the book, met the Honourable Lucy Cole, who was working in publishing; they were married in 2007. He also cannibalised and converted the Doctor's TARDIS into a paradox machine to change history, and took Lucy to see the universe. (TV: The Sound of Drums)

Travelling back to the end of the universe, the Master contacted the Toclafane, the childlike, vicious cyborg remnants of the humans who had never found Utopia. He made an agreement to allow the Toclafane to escape extinction and live anew in the past, with the paradox machine preventing them from changing their own history. (TV: The Sound of Drums, Last of the Time Lords)

Under the guise of "Harold Saxon", the Master entered the government as Minister for Communications, an office under which he designed the Archangel Network which was hailed as a telecommunications breakthrough. This telecommunications network, tied to mobile phones, carried a mind control signal which made humans trust him. The network affected the Doctor so he had no suspicions as to the Master's presence as "Harold Saxon", as he would have normally noticed the presence of another Time Lord. To those few humans conscious of it, the signal was a persistent drumbeat, the constant drumbeat the Master always heard, that only they could hear.

By 2007, "Saxon" had become Minister of Defence of Great Britain, and had been a driving force in designing the Valiant, UNIT's air carrier. (TV: The Sound of Drums) He went on to campaign for the general election as Prime Minister of Great Britain (TV: Love & Monsters) with the slogan "Vote Saxon". (TV: Captain Jack Harkness) On Christmas Eve, he gave orders for British Army tanks to destroy the Empress of the Racnoss's webstar. (TV: The Runaway Bride)

The Master visited "Saxon's" old high school during the campaign, using the Archangel Network to brainwash the staff into having false memories of "Saxon" to gain political support. One teacher, James Curtis, was resistant to the Network, so the Master used his laser screwdriver to implant the appropriate memories into his mind. (PROSE: Speech Day)

"Saxon" asserted that extraterrestrial life did exist and Britain had to do something about it. This made him popular in early 2008, after the Judoon had taken the Royal Hope Hospital to the Moon. (TV: Smith and Jones)

"Saxon" also funded the rejuvenation experiments of Richard Lazarus, presumably revealing at least in part the biological processes involved in a Time Lord's physical regeneration; its similarities were noted by the Doctor on observing the process. (TV: The Lazarus Experiment) With the results from this and the Doctor's DNA, the Master could use the laser screwdriver to age the Doctor. (TV: The Sound of Drums) After Martha had left with the Doctor, "Saxon" had a mysterious man meet with Martha's mother, Francine, (TV: The Lazarus Experiment) and then had an agent tap into a conversation between Francine and Martha through the superphone. (TV: 42)

Before the Doctor, Martha and Captain Jack arrived back from the end of the universe, the Master had sent Torchwood Three on a wild-goose chase to the Himalayas, (TV: The Sound of Drums) and, along with all other incarnations of the Master, was kidnapped by the Sild. (PROSE: Harvest of Time) The Master also taught the Disciples of Saxon how to create the Potion of Life, and made preparations to be resurrected in the event of his death. (TV: The End of Time)

Prime Minister Saxon
With his election a sure thing, politicians from other parties flocked to his side. Harold Saxon was elected Prime Minister of the United Kingdom in May 2008, and visited Buckingham Palace soon after to give a victory speech.

He gathered his Cabinet for a meeting in the re-built 10 Downing Street and accused them of being traitors for abandoning their political parties to jump on his political ticket. He rigged the desk phone speakers on the Cabinet Room table to release a lethal gas that killed the Cabinet ministers while using a gas mask to protect himself and mock his victims. He later unleashed the Toclafane on Sunday Mirror reporter Vivien Rook, who threatened to expose his fabricated past to the public.

"Saxon" told the public that the Cabinet had gone into seclusion, and soon afterwards announced first contact with the "friendly" Toclafane who could protect Earth against alien threats. The Master then had Francine, Tish and Clive Jones arrested and taken to the Valiant; Leo Jones, however, had received a warning from Martha and gotten away in time. During a telephone conversation with the Doctor, the Master had the Doctor, Martha and Jack framed as terrorists responsible for the Cabinet's murder and forced them into hiding. (TV: The Sound of Drums)

The Year That Never Was
The Master moved to the Valiant, which the governments of Earth considered neutral territory and therefore fitting for formal first contact with alien life. The Master had the Toclafane murder the American President Arthur Coleman Winters and captured the Doctor, Martha and Jack, who had come to the Valiant earlier that day. Using the results from Professor Lazarus's experiment, along with the DNA in the Doctor's hand, the Master used his laser screwdriver to age the Doctor into an old man, and then ordered the Toclafane to kill one tenth of humanity and commence their invasion as Martha escaped. (TV: The Sound of Drums)

While ruling the world for a year, the Master discovered that the Drast had secretly invaded before he arrived. Furious, he ordered the Toclafane to burn Japan, where the Drast were situated. (PROSE: The Story of Martha) By 2009, the Master had converted Earth into a slave camp which he ruled from the Valiant. The Master aged the Doctor even further and planned to expand his New Time Lord Empire into space. He built an army of warships to take his war across the universe.

Martha used the legend of the Doctor, which she had spread, and the thoughts of Earth thinking "Doctor" at the same time. Their psychic energy was channeled through the Archangel Network, which the Doctor had spent the year infiltrating telepathically. The psychic energy restored the Doctor and gave him telekinetic powers. After cowering from the Doctor's forgiveness, the Master used Jack's vortex manipulator to teleport him and the Doctor to Earth, where he threatened to use the black hole converter to detonate the rockets, but was foiled by the Doctor's knowledge that the Master could not kill himself.

Jack destroyed the Paradox Machine and reversed time one year, although this did not affect anyone aboard the Valiant. Lucy shot the Master. Defeated, he refused to regenerate to spite the Doctor, and died in his arms, (TV: Last of the Time Lords) having already made the preparations for his resurrection. (TV: The End of Time) The Doctor burned the Master's body on a pyre, (TV: Last of the Time Lords) but, long after he had left, Miss Trefusis, one of the warders of Broadfell Prison, (TV: The End of Time) retrieved the Master's ring from his funeral pyre. (TV: Last of the Time Lords)

As far as the general public were aware, Harold Saxon "went mad" and disappeared, along with President Winters. (TV: The End of Time) Among all ex-Prime Ministers, Saxon was on file by UNIT, who noted him as one of the Master's incarnations. (TV: Death in Heaven) By the year 2119, Saxon was well-remembered enough that Alice O'Donnell referred to 1980 as "pre-Harold Saxon". (TV: Before the Flood)

Rassilon's Final Solution
On Christmas Eve 2009, the prison governor of Broadfell Prison brought Lucy Saxon to a chamber where most of the staff were members of the Disciples of Saxon, who had been working ever since the Master's death to bring about his resurrection. With the help of the ring and a biometric imprint taken from Lucy, the nude Master reappeared in a swirl of energy, but Lucy and one other warder had prepared for this. To stop his resurrection, Lucy hurled a Potion of Death at the Master. His followers and Lucy were killed in the resulting explosion.

The Master survived the blast, but his physical form was flawed: his once-brown hair was now bleached blond, and he was unkempt and covered in stubble. Moreover, his life force was left in a state of constant depletion, forcing him to consume huge quantities of food and drain the vitality of humans to stay alive. As a side effect of the botched resurrection, he could expend his life force for enhanced agility and send bolts of energy from his hands. The Master's body would even fluctuate between a fleshy form and a half-skeletal state.

The Master led the Doctor on a wild goose chase after banging the beat of the drums in his mind to lure the Doctor to him and escaped when Wilfred Mott interrupted the chase.

Encountering the Doctor soon after, the Master and the Doctor discovered the drumming in the Master's head was real, not just a symptom of insanity. The Doctor also told him of the prophecy told to him by the Ood, but the Master quickly dismissed it, assuming that it was referring to him. Billionaire Joshua Naismith then captured the Master and enlisted his assistance to mend the malfunctioning Vinvocci medical machine, which he had christened the "Immortality Gate". The Master co-operated for his own purposes. He broke out of a straitjacket and flew into the gateway, which he had working a billion fold on the human template. The gateway sent out an energy pulse that transformed every human on Earth, except Wilf, whom the Doctor protected with a radiation shield, and his granddaughter, Donna Noble, who was unaffected due to her part-Time Lord physiology, into the Master Race — identical copies of the Master subservient to him.

After the Doctor and Wilf were rescued from the Master by two Vinvocci, the Master used the combined mental powers of the Master Race and a White-Point Star that had fallen on Earth to trace the origin of the drumbeat in his head. Receiving contact from the Time Lord High Council on the last day of the Time War, the Master tore open the time lock on the war, bringing back the Time Lords.

As the Lord President Rassilon and his council arrived through the Immortality Gate, the Master announced he intended to transplant himself into the entire Time Lord race, just as he had done to the human race. Rassilon, using his gauntlet, reversed the effects of the Master's transplantation, and watched as Gallifrey returned to the universe on a collision course with Earth. The Doctor berated the Master for breaking the time lock, warning him that it wouldn't just be the Time Lords and the Daleks, and that he had just opened up "Hell".

Rassilon revealed his plans for the Ultimate Sanction; the Master asked if he could also "ascend into glory", but Rassilon rebuffed him, calling him "diseased" and revealed that he was responsible for the drumming that the Master had experienced all of his life, and prepared to execute him, but the Doctor stepped in with Wilfred's pistol. After some hesitation on whether to shoot Rassilon or the Master, he shot the White-Point Star, destroying the link. Enraged, Rassilon prepared to kill the Doctor, but the Master unleashed his bio-electric blasts at the President, roaring that the Time Lords had manipulated him and made him the monster he had become, counting the beat of the rhythm that had resounded in his head and tormenting him all his life. The Time Lords, Gallifrey, and the Master then vanished in a burst of white light, and were sent "back into [the] hell" of the final day of the Time War. (TV: The End of Time)

While the Moment foresaw the battle as ending with the Master and Rassilon both regenerating, (PROSE: Pandoric's Box) the Master was able to survive his encounter with Rassilon, though Rassilon still regenerated after the Master choked him with several White-Point Stars. (PROSE: Lords and Masters) After his "condition" was cured by the Time Lords, (TV: The Doctor Falls) the Master escaped Gomer's Asylum, blowing up the War Room in the process, (PROSE: Lords and Masters) and left Gallifrey in his TARDIS, seeing his departure as "a mutual kicking [him] out." (TV: The Doctor Falls)

After leaving Gallifrey
Still possessing blond hair and stubble, (COMIC: The Abominable Showmen) the Master was greeted by a who had developed a plan to form a band to hypnotise viewers of The Battle of the Bands Beyond the Stars. , and  all joined in the plan, and the team spent "decades" practising. (COMIC: The Five Masters) Much to this Master's appreciation, he was allowed to play the drums. 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 other Masters soon joined in the fight for power as well, while the "Saxon" Master joined seemingly for the fun of it. The five were quickly disqualified, seemingly destroying them. (COMIC: The Five Masters)

The Mondasian colony ship
Eventually, the Master landed on a Mondasian colony ship which was experiencing time dilation due to pulling itself away from a black hole, and took over the city on Floor 1056, where he "lived like a king until they rebelled against [his] cruelty". Attempting to escape, but being "too close to the event horizon", the Master burned out his TARDIS's dematerialisation circuit, stranding him on the colony ship. (TV: The Doctor Falls) Disguising himself as "Razor", the Master oversaw the "genesis of the Cybermen" with Operation Exodus.

While working for a hospital hosting the Conversion Theatre, the Master found Bill Potts, who had been given a cybernetic chestpiece after being shot on Floor 0000. (TV: World Enough and Time) The two of them spent ten years on the lower decks, (TV: The Doctor Falls) where the Master learned that the Twelfth Doctor was at the front of the ship. Studying the woman travelling with the Doctor,, the Master eventually deduced that she was a future incarnation of himself trying to turn good. Becoming "concerned about [his] future", the Master lured Bill into surgery for full cyber-conversion, knowing that the Doctor would never forgive him for it. Watching as the Doctor, Nardole, and Missy arrived, the Master revealed his identity to Missy, and the two of them gloated to the Doctor about the fate of his companion. (TV: World Enough and Time)

Restraining the Doctor before taking him to the hospital roof, the Master flirted and danced with Missy until the Cybermen turned on them due to the Doctor tinkering with the computers. Just as Nardole arrived with a stolen shuttlecraft, the Doctor was attacked by one of the Cybermen. The Master and Missy attempted to convince Nardole to leave without him, but their shuttle was stopped by the Cyber-converted Bill, who still retained her humanity. Crashing through 549 floors of the colony ship, the shuttlecraft gave out at one of the solar farms. (TV: The Doctor Falls)

While the Doctor recovered from their escape, the Master, accompanied by Missy, ventured back down the colony ship to revert the Doctor's tinkering and regain control of the Cybermen, though they were followed by Alit. Ultimately, however, the Master was unable regain control of the Cybermen. (PROSE: Alit in Underland)

After two weeks of searching, the Master and Missy found disguised lifts, but Missy accidentally summoned the Cybermen in her attempt to escape. Unable to return to the Doctor's TARDIS due to how quickly time was moving on the floor of the Cybermen, the Doctor insisted that they had to prepare for a confrontation.

As the Doctor prepared to fight, the Master explained to Missy how he had blown the dematerialisation circuit in his TARDIS, which was surrounded by Cybermen on the bottom floor. Missy, recalling an instance where a very scary woman had pushed him up against a wall and insisted that he always keep a spare dematerialisation circuit, pushed the Master against the wall and insisted that he always keep a spare dematerialisation circuit, revealing the spare dematerialisation circuit she kept on her person. Before departing, however, the pair asked what the Doctor's plan was, knowing that he wouldn't be able to save everyone on the ship. As the Doctor explained that he wanted to save these people simply because it was the right thing to do and tried to implore the Master to stand with him in the battle, the Master made his refusal of the offer known, and he left with Missy. (TV: The Doctor Falls)

Death
As they prepared to depart, Missy offered to hug the Master and, after stating her enjoyment for being him, she stabbed the Master in the back, mortally wounding him in order to force his regeneration into her. However, Missy made the wound precise so that the Master would have time to reach his TARDIS before the regeneration occurred. As he was helped into the lift, the Master asked Missy to explain herself, and she told him she planned to stand with the Doctor, believing they had been leading towards it their entire lives. Furious, the Master declared that he would never stand with the Doctor, and shot Missy in the back with his laser screwdriver at full blast, mortally wounding his future incarnation past the point of regeneration. Laughing, the Master declared that their perfect ending was always going to be "shoot[ing] [them]selves in the back." Still laughing and in pain, the Master returned to Floor 1056 in the lift, leaving Missy to die alone. (TV: The Doctor Falls)

After returning to his TARDIS, the Master regenerated into his nineteenth incarnation, (PROSE: Girl Power!) the same incarnation that had fatally wounded him. (TV: The Doctor Falls)

Personality
Immediately after his regeneration, the Master appeared to have gone more insane than ever, gleefully jumping around the Doctor's TARDIS' control console, while ecstatically laughing, and toying with his new voice. (TV: Utopia) By this point in his life, the Master was tormented more than ever by "the drums" in his head, (TV: The Sound of Drums) but, after his sabotaged resurrection, he admitted to seeing it as a central piece of his identity, convinced that something was calling to him through the drum beat. (TV: The End of Time) So much was he obsessed with them, that, on one occasion, "the drums" was all he would say. (COMIC: The Abominable Showmen, The Five Masters) On another occasion, however, the Master fearfully asked the Doctor if he thought "the drumming" would stop after he died. (TV: Last of the Time Lords)

Much like his previous incarnations, this Master was ostentatious; offering out jelly babies and grits, (TV: The Sound of Drums) opting to wear eyeliner in preparation for being a woman in his next incarnation, (TV: The Doctor Falls) and dancing to the Rogue Traders, (TV: The Sound of Drums) and the Scissor Sisters. (TV: Last of the Time Lords) He also enjoyed watching the Teletubbies, believing that the televisions in their stomachs was true evolution, (TV: The Sound of Drums) and thrived on chaos, describing the last day of the Last Great Time War as "[his] kind of world", (TV: The End of Time) and was excited about getting into fights. (COMIC: The Five Masters; TV: The Doctor Falls) He also admitted to loving disguises, (TV: World Enough and Time) and was particularly outraged when he was "stuck looking like the old Prime Minister." (TV: The End of Time)

Behind his charismatic and charming demeanour, however, this Master was sadistic and childishly degrading, even going as far as to slip subtle and private jabs at the Doctor into his public speeches. When Francine, Clive and Tish were forcibly taken to the Valiant under armed guard, the Master shamelessly treated the ordeal like a school field trip, (TV: The Sound of Drums) and, during the Year That Never Was, he kept them as slaves, taking every opportunity he could to belittle them, even goading Francine into murdering him, until the Doctor convinced her otherwise. (TV: Last of the Time Lords) He also made Bill Potts aware of his part in her Cyber-conversion to upset her, and was disappointed when his remarks seemed to have failed, stating that she had "[taken] all the fun out of cruelty". He was also alarmed and disgusted at the idea of his future self gaining empathy, (TV: The Doctor Falls) and disliked being interrupted. (PROSE: Alit in Underland)

He was extremely vain and narcissistic, with the Tenth Doctor noting that he would never destroy himself, even if he could destroy the Earth with him. During the Year That Never Was, he had monuments of himself built all over Earth, and, according to Martha Jones, had even sculptured himself onto Mount Rushmore. (TV: Last of the Time Lords) He also used the Immortality Gate to turn the human race into duplicates of himself, which he dubbed the "Master Race", and also threatened to do the same to the Time Lords, even asserting that Rassilon "[would] [look] better as [him]." (TV: The End of Time) His vanity was so vast that when the Tenth Doctor forgave him for his actions, the Master collapsed and wept out of shame. After he expressed revulsion at being "kept" by the Doctor, the Master was shot by Lucy and, to spite the Doctor, decided not to regenerate and die. (TV: Last of the Time Lords) After meeting his female successor,, the Master admitted to being attracted to his future self, flirting and dancing with her. However, when he saw the possibility that Missy would aid the Twelfth Doctor, the Master killed her. (TV: The Doctor Falls)

This Master also had an exceptionally heightened sense of his own brilliance, even reciting a Bible-style verse of his own making to the Doctor as the Toclafane invasion began. (TV: The Sound of Drums) He also held Time Lords as the absolute superior race, automatically assuming the right to alter history on the principle of him being a Time Lord, (TV: Last of the Time Lords) and was confident that he could beat an entire city of Cybermen while only being armed with his laser screwdriver. (TV: The Doctor Falls) However, when his plans were foiled, the Master would turn cowardly, retreating at the first opportunity or allying with whoever could better protect him. (TV: Last of the Time Lords, The End of Time, The Doctor Falls)

The Master still held the lives of others without thought, assassinating the Cabinet of the United Kingdom, setting the Toclafane on Vivien Rook, ordering Arthur Coleman Winters's execution as a show of power, commanding the decimation of the population of Earth to emphasise his new dominion, (TV: The Sound of Drums) destroying the islands of Japan when he learned that the Drast had been operating in Yokohama, (PROSE: The Story of Martha) siphoning the life forces of the people who resurrected him, and unceremoniously consuming Sarah, Tommo and Ginger, leaving them as skeletons. (TV: The End of Time) He also showed a sadistic glee when he resorted to murder, continuously listening in on Rook's dying screams, being excited by the prospect of killing the immortal Jack Harkness a second time, (TV: The Sound of Drums) and chuckling after casually killing Thomas Milligan. (TV: Last of the Time Lords) He was also known to kill those who brought him bad news. (PROSE: The Story of Martha)

The Master was somewhat misogynistic, believing that women had "a way of disappointing [him]", and were "fickle" for being "lovey-dovey" at one moment and trying to kill him in an instant. (PROSE: Alit in Underland)

This Master showed minimum affection for the Doctor. Even after he aged the Tenth Doctor to an elderly man, (TV: The Sound of Drums) the Master continued to humiliate him by having him live in a makeshift tent aboard the Valiant during the Year That Never Was, and then furthered the humiliation by ageing the Doctor until he morphed into an ancient dwarf-sized body, and then kept him locked up in a bird cage. (TV: Last of the Time Lords) When told him of her plans to join forces with the Twelfth Doctor, the Master adamantly stated his refusal to stand with the Doctor and killed Missy with his laser screwdriver. (TV: The Doctor Falls) The Master was even willing to die to spite the Tenth Doctor, (TV: Last of the Time Lords) and claimed to prefer death than begging for the Twelfth Doctor's help. (TV: The Doctor Falls)

However, this Master was not without his reservations, considering Rassilon's Ultimate Sanction to be suicidal, but was still willing to subject himself to it to appease Rassilon. He also had a sense of honour, as he sacrificed himself to save the Doctor from Rassilon after the Doctor chose not to kill either of them, also getting his revenge on Rassilon for implanting "the drumming" in his head, and for Rassilon trying to kill him for being "diseased". (TV: The End of Time)

While he originally avowed affection for his wife, Lucy Saxon, (TV: The Sound of Drums) the Master's vanity and overconfidence in his successful taking of Earth led him to forego such pretences, even teasing her with the possibility of replacing her with his masseuse. He was, however, unsurprised when she shot him, instead making a quip about it "always [being] the women". (TV: Last of the Time Lords)

After his sabotaged resurrection, the Master displayed a feral state that led him to act like a predatory animal, plagued by an insatiable hunger. Despite this insanity, the Master was capable of lucid conversation, nostalgically discussing his childhood friendship with the Tenth Doctor. He was also still a cunning strategist, allowing himself to remain Joshua Naismith's prisoner so he could repair the Immortality Gate and use it to create his Master Race, all so he could turn the Earth into a warship, but then improvised a plan where he used his duplicates to locate the source of "the drumming". (TV: The End of Time) The insanity he developed due to his botched resurrection and the drumming was fixed when the Time Lords repaired the Master's body back to normal. (TV: World Enough and Time, The Doctor Falls)

Missy recalled an enjoyment for being in this incarnation, stating how he "burn[ed] like a sun, like a whole screaming world on fire." (TV: The Doctor Falls) Alit described the Master as being "an odd and frightening man" with a habit for "nasty comments and exaggerated gestures". (PROSE: Alit in Underland)

After he was fatally stabbed by Missy, the Master admired how his death was "very nicely done", and found that it was "good to know [she] [hadn't] lost [his] touch." Though he accepted his impending regeneration, the Master was unwilling to accept that Missy would stand with the Doctor, and shot her dead. He then began laughing at their "perfect ending" being them "shoot[ing] [them]selves in the back", and continued to laugh as he made his way to his TARDIS. (TV: The Doctor Falls)

Habits and quirks
The Master made a habit of saying, "Oh, no you don't", saying it when the Doctor was locking the TARDIS's coordinates, (TV: Utopia) when avoiding a conversation with the Doctor, when the Doctor restored his youthful physiognomy with the Archangel Network's telepathic link, (TV: Last of the Time Lords) and when fending off a Mondasian Cyberman. (PROSE: Alit in Underland)

Skills
The Master shared the Tenth Doctor's technical knowledge, as he was able to construct his laser screwdriver from Earth components, cannibalise the Doctor's TARDIS and turn it into a Paradox machine, miniaturise Richard Lazarus' genetic manipulation technology, (TV: The Sound of Drums) and was able to repair the Immortality Gate for Joshua Naismith. (TV: The End of Time) He also designed the Archangel Network and the Valiant. (TV: The Sound of Drums)

Like his degenerated and bald incarnations, this Master had dangerous foresight and knew it was a mistake to give the Doctor hints about his plans while he could intervene. (TV: Utopia) His methods for dealing with the Doctor during his reign as prime minister showed an efficient and simple mindset; framing the Doctor for murder to send the police after him, arresting Martha's family for insurance, and luring Torchwood Three away to the Himalayas to prevent Jack from recruiting their aide. (TV: The Sound of Drums) He was likewise straight to the point when explaining how the time differentials were affecting the Mondasian Colony ship to Bill Potts. (TV: World Enough and Time)

This Master was also a decent fighter, having brawled with his other incarnations on equal footing, (COMIC: The Five Masters) struck the Tenth Doctor down with a single punch to the face, (TV: Last of the Time Lords) knocked down a partially-converted Cybermen with a blow to the back of their head, (TV: World Enough and Time) and overpowered the Twelfth Doctor in unarmed combat. (TV: The Doctor Falls)

Appearance and clothing
In his eighteenth incarnation, (PROSE: Girl Power!) the Master was young, with light brown hair, and dark brown eyes. (TV: Utopia) According to the Twelfth Doctor, he had a "round face". (TV: The Doctor Falls) As "Harold Saxon", the Master would wear a black suit with a white shirt and black tie. While meeting President Arthur Coleman Winters, he wore a black coat with a crimson lined interior. (TV: The Sound of Drums)

After his botched resurrection, the Master's hair was bleached light blond, and he gained some stubble. To remain inconspicuous, he wore a black hooded sweatshirt over a red T-shirt with dark combat trousers and black boots. Due to the corruption of his life force, the Master's outer skin would fade away and reveal the translucent blue life energy encasing his body, exposing his skeleton and internal organs, with each fluctuation making an unsettling primal roar. (TV: The End of Time) After being "fixed" by the Time Lords, the Master no longer distorted into the translucent blue energy. (TV: The Doctor Falls)

By the time he found the Twelfth Doctor aboard the Mondasian colony ship, the Master had aged somewhat, now having grey hair and a beard. He also discarded his previous clothes for a black coat with a large red lined collar on the left-hand side, a green button up shirt, (TV: World Enough and Time) dark trousers, and black zip-up boots. (TV: The Doctor Falls)

When the Third Doctor saw this Master in Sild captivity, he described what he saw as "a young man in a business suit, beardless, with a mop of boyish hair," and that his face "seemed friendly and plausible", overall thinking him "the kind of man people would find easy to trust." (PROSE: Harvest of Time)
