Koschei incarnation

(Divided Loyalties (fb)) Koschei of the House of Oakdown is at the Time Lord Academy at the Capitol. He has become a member of the Deca, a group of students far smarter than the average Gallifreyan. One of his closest friends is a fellow Prydonian who has just adopted the name, the Doctor.

Delgado incarnation

(Reconnaissance)

(Terror of the Autons) Now calling himself the Master, Koschei makes contact with the Nestene Consciousness, and strikes a deal with them to help them conquer the Earth. He does this mostly to plague his old friend the Doctor.

back to Beevers incarnation

(Dust Breeding) The Master attempts to cleanse his form of the Cheetah virus, but his method backfires, and instead his form is blasted backwards through its own timeline, returning him to the scarred and dying form he inhabited just prior to the theft of Tremas body.

(Master)

(First Frontier) Having somehow figured out a way of restoring his body to the Tremas form, the Master is disappointed to discover he still carries the Cheetah virus in his cells. Allying himself with the Tzun, whose knowledge of genetics are without peer, he strikes a bargain with them to have them develop nano-probes which will cleanse his form and allow him to regenerate again.

Eric Roberts incarnation

(Doctor Who: The Movie) His own body destroyed by the Daleks, the Master survives as a consciousness inhabiting a symbiotic deathworm. He uses this temporary form to steal the body of an ambulance man, killing his victim in the process. Trapped now in a decaying form, he only has a short time left to him to transfer his mind into something more permanent - such as the newly regenerated Doctor.

Preacher incarnation

(The Fallen) Trapped in the Vortex, the Master's mind makes contact with Estarath the Gatherer, who restores him to corporeal form in the revived corpse of a wino on Earth.

(The Glorious Dead)

Derek Jacobi incarnation

(The Adventuress of Henrietta Street) Having somehow survived all his recent misfortunes, and the destruction of the entire Time Lord civilisation, the Master attends the Doctor's wedding. He is temporarily sans beard, as the Doctor has grown one, and the Master feels he must always be the Doctor's polar opposite.

(The Screams of the Shalka)

Delgado alternate

(Sympathy for the Devil) The Master arrives on Earth, just as in Terror of the Autons. But the Doctor has not begun his exile to Earth, and the Master is trapped there, forced to watch as UNIT handles the same threats the Doctor would have, only using far greater force. Without the Doctor's aid, the peace initiatives with China fail, and the world is a far darker and more violent place. The Master works for the UN for a while, before defecting to the Chinese, where he uses the mind parasites seen in The Mind of Evil to brainwash political dissidents into becoming suicide shock troops for the Chinese government. When all the parasites reach the point where they can absorb no more, the Master realises those troops will soon regain their memories. He locates the last, uncollected parasite, kept prisoner in a monastery in Hong Kong, and steals a stealth plane to go there the day before the British hand the colony back - his plan, to gain control of the creature and then use this as a bargaining chip to be appointed ruler of the world. However the plane crashes while landing, and he is fatally injured.

Kisgart incarnation (one subsequent to Delgado)

(Sympathy for the Devil) Regenerating, the Master kills a witness who had come to see if there were any survivors who might need help, and steals the man's clothes. He then makes his way to the monastery where he encounters the newly arrived Doctor (recently regenerated into the Warner incarnation).

Pryce alternate

(The Curse of Fatal Death) In another timeline the Master plots the Doctor's death, but accidentally broadcasts his plans directly into his adversary's TARDIS.

Delgado Master's apocryphal appearances

(Fogbound)

Ainley Master's apocryphal appearance

(Destiny of the Doctors) The Master somehow traps all the different incarnations of the Doctor in a virtual reality, and it is up to the Doctor's newest ally to rescue him.
