The Master (Doctor Who)

"I only need two things. Your submission and your obedience to MY WILL!"

- The Master

The Master is a powerful supervillain from the Doctor Who series. He is a member of the Time Lords and is the archenemy and former childhood friend of the Doctor.

Beginning
The Master's madness appeared to have began at the age of eight when he was taken before a gap in the fabric of space and time known as the Untempered Schism as part of a Time Lord initiation ceremony. Since then, the Master has been plagued by the four-beat sound of drums, believing them to be the "drums of war", and became into a would-be universal conqueror. Like the Doctor, he got his own TARDIS and continued doing evil until he met the Doctor again, when he was already in his Twelfth incarnation.

Reunion with the Doctor
The Master first encountered the Doctor during his Third incarnation when he was trapped on Earth. Wanting to make the Doctor suffer, the Master allied himself with various evils like the Nestene Consciousness or the "Sea Devils", a mutated version of the Silurians, to undermine UNIT. After the Master's scheme to provoke a war between the Human and Draconian Empires on behalf of the Daleks (though he was planning to betray them) failed, the Master retreated.

The Master in his New Bodies
By the time he meets the Fourth Doctor, the Master's body is at its final incarnation and severely rotting. Despite the Doctor keeping him from extending his life with the artefacts of Rassilon, the Master cheats death by transferring his being into the body of a Trakenite scientist named Tremas.

In his new body he heads to Logopolis to accomplish another evil plan which gets out of control soon, resulting in the Doctor having to work together with him to save the universe. However, after they stabilise the Charged Vacuum Emboitment, it turns out that the Master actually wants to threaten the universe to accept his rules. The Doctor is able to stop him, but is killed and has to regenerate into the Fifth Doctor. To get revenge, the Master lures the Doctor to the city Castrovalva where he poses as the librarian Portrevee. After the Doctor foils his plan the city disappears along with the Master. However the Master returns by unexplained means, still searching for a way to extend his life.

When the five Incarnations of the Doctor were kidnapped by Borusa, the Time Lords promised the Master new regenerations if he could save the Doctor. The Fifth Doctor didn't trust him and was teleported away, so he allied the Cybermen to get to the Tower of Rassilon, hoping to receive immortality.

Although the Doctors can capture him, the Master is able to continue with his evil deeds at the Doctor's future incarnations: This includes teaming up with the Rani, interfering in the trial of the Valeyard against the Sixth Doctor or bringing an evil cat-like alien race to Earth, before he is finally left behind on their dying planet by the Seventh Doctor, while being turned into one of them by a virus.

The Master's End
Eventually, the Master is executed by the Daleks as a punishment for his "evil crimes". But he survives his execution by transferring his mind into a small, snake-like morphant that slithers inside the Seventh Doctor's TARDIS console, forcing the vessel to crash land in San Francisco on December 30, 1999 where it enters the body of a paramedic named Bruce. But as Bruce's body is unsustainable and begins to slowly degenerate, the Master attempts to access the Eye of Harmony with help of a teenager named Chang Lee, who he has convinced the Doctor is evil, to steal the Doctor's remaining regenerations, but instead is sucked into it and killed.

Eyes of the Master
The Time Lords saved the Master due to the danger of the Daleks. They detected a possible timeline where the Eminence, a sentient gas that took control of humans, would become the final lifeform in the Universe. The Time Lords hoped to use the Eminence against the Daleks and the Celestial Intervention Agency gave the Master the information he needed.

The Master travelled to the Nixyce System and stole an Eminence Teleportation casket, integrating it into his TARDIS console. In 1970s London he posed as Dr Harcourt Diath and performed experiments on human immunity to the Eminence, hoping to remove it so the Eminence wouldn't be defeated. He saved Dr Sally Armstong from being hit by a taxi and recruited her. The Master removed people's eyes, curing blindness but enabling him to see through their eyes and control them. He encountered the Eighth Doctor, who told an Eminence located in his mind how to pilot a TARDIS. Using the casket in the Master's TARDIS it piloted it away with the Master and Sally. However using the telepathic circuits of his TARDIS the Master isolated the Eminence and Sally expelled it into the Time Vortex.

Some time later, Sally and the Master kidnapped Molly O'Sullivan from her home in 107 Baker Street.

The Time War
During the Time War with the Daleks, the Time Lords resurrected the Master to aid them as the ultimate front line soldier. But after the Dalek Emperor took control of "The Cruciform", the Master fled the war in fear, ignorant of its outcome as he uses a Chameleon Arch which stores his Time Lord nature and memories in a fob watch and allows him to become biologically human.

Ended up at the end of the universe, the Master's incarnation aged into the scientist, Professor Yana. The Professor was still plagued by the constant drumbeat in his head as he attempts to send the last remaining humans to Utopia where they apparently would be save, as the entire universe was collapsing.

The Master's Return
When the Tenth Doctor and his companions Martha Jones and Captain Jack Harkness arrive, he tells them about the end of the universe and his plans. Joining him in his laboratory to support him repairing his rocket, they accidently cause Professor Yana to recall his Time Lord essence and become the Master once more, although they were actually trying to help him to reach Utopia. Mortally wounded when his companion Chantho shoots him with a gun after he fatally injured her with electricity, the Master regenerates into a new younger incarnation.

The Master steals the Doctor's TARDIS, which he later even converts into a "Paradox Machine". But as Doctor sabotages the TARDIS using his sonic screwdriver so he can only able to travel between Earth 2007 and the year 100 trillion, the Master assumes the identity Harold Saxon and makes his way to becoming England's Minister of Defense and later Prime Minister.

As Harold Saxon, the Master secretly interfered with the Doctors and Marthas life, for example through the scientist Richard Lazarus, who made himself younger and mutated into a monster. From there, Master uses the Doctor's TARDIS to recruit the Toclafanes from Utopia, where they emerged from the last humans, as allies, having them kill one tenth of the world population. From that day onward, the Master rules Earth for a year, while turning whole nations into work-camps and bases for a fleet of war rockets. He holds the Doctor, aged by Lazarus' invention, and Captain Jack captive, while only Martha is able to escape.

However, the Doctor reverses the events by the help of Martha, with the Master shot by his wife Lucy Saxon and refusing to regenerate as his death is a small victory to emotionally hurt the Doctor. Though the Doctor cremates the Master's body on a pyre, his ring remains and is obtained by coven loyal to him.

Creation of the "Master Race"
By Christmas 2010, as the Ood foretold, the Master's coven conduct resurrects the Master at Broadfell prison, where Lucy was incarcerated before she sacrifices herself to sabotage the ritual. However, it only revived the Master in failing body with a ravenous hunger.

Resorting to wandering the fringe of London and feeding on homeless people while being pursued by the Doctor, learning the sound of the drums is a signal, the Master is eventually captured by billionaire Joshua Naismith in order to use his knowledge to repair an alien 'Immortality Gate' to make Naismith's daughter immortal. But the Master hijacks the device, using its original purpose as a planet-wide medical tool to overwrite the DNA of every human on Earth with his own and create a "Master Race".

Using his duplicates, the Master triangulates the signal to its source: The Time Lord President Rassilon before obtaining an unique Gallifreyan diamond to create a link through which the Time Lords emerged. Though he intended to overwrite his DNA onto the Time Lord race, the Master's work on the human race is undone as he learns the truth that he was nothing more but a pawn in Rassilon's plan to destroy all creation so he and the other Time Lords can transcend into beings beyond time. When the Doctor destroys the link, the Master attacks Rassilon to save the Doctor in an act of revenge for a lifetime of manipulation, disappearing into Gallifrey with the other Time Lords in the process.

Missy
Following this, The Master regenerated into a woman and started going by the name of Missy (short for Mistress). She welcomed the Half Face Man to the Nethersphere which she called Heaven and joked to him that the Doctor was her boyfriend. She later welcomed a soldier called Gretchen and offered her tea. Later she watched over Clara making sure she stayed with the Doctor. She gave her the number of the TARDIS phone and made sure the she reunited with the Twelfth Doctor. She later watched as the Earth was saved from a solar flare.

She was in fact in league with the Cybermen and eventually revealed who she really was to a rather shocked Doctor, along with the fact that the Nethersphere was actually a globe of Time-Lord technology, situated within St. Paul's cathedral and that she had syphoned the consciousness of everyone who had recently died into the Nethersphere. The Master's, or rather, Mistress's plan is to send each of the minds within the Nethersphere into the body of a Cyberman with which to conquer the Earth. Whereas as The Master had always identified as heterosexual in the past, as a result of now becoming a woman, she seems to have developed a very flirtatious relationship with the Doctor, even kissing him on the lips, however she also flirts with Clara. Her plan to conquer Earth using drones made from dead humans is actually a recycled version of the Emperor Dalek's plan. After her plan failed she asked if either the Doctor or Clara wanted to kill her, when neither wanted to do it she was shot by another Cyberman (revealed to be the Doctor's late ally Brigadier Lethbridge Stewart) and disintegrated.

Personality
The Master is deeply megalomaniacal and shows signs of psychopathic behavior as his greatest fear in the universe is being outdone by the Doctor - leading him to becoming obsessed with ruining everything the Doctor stands for. This has served to make the Master one of the Doctor's greatest and most reoccurring opponents and also the one that has caused the most emotional pain to the Doctor during the decades long feud between the two characters. Like every Time Lord, the Master changes his looks and personality slightly every time he regenerates to escape death.

Trivia

 * The Master's relation with the Doctor can be compared to that of James Moriarty and Sherlock Holmes.
 * In the episode "The Final Game", The Master (in his 1st incarnation) was supposed to be revealed as the Doctor's dark side or his brother and he should die by sacrificing himself to save the Doctor. However, the episode was never made because the actor Roger Delgado died in a car accident in Turkey. Still the idea of a dark side of the Doctor was used for The Valeyard.
 * The Master is the first known Time Lord to be able to change gender via regeneration.
