This page lists appearances of the Decayed Master played by Geoffrey Beevers and Peter Pratt in the order in which he experienced them. It relies on much speculation to fit semi-contradictory sources together, and should absolutely not be seen as representative of this wiki's general policy.

The last incarnation of the Master in his first regeneration cycle, this incarnation spent much of his life in a decaying state, before finding various ways to steal bodies from various sources, including the Source and Deathworm Morphant. Each body he steals appears to come with a new set of personality traits and so are often considered to be separate incarnations.

Timeline

Body decayed

According to this account, the "Decayed" Master is, in fact, the "UNIT enemy" Master, his body damaged beyond the point of regeneration after being shot with the TCE by Susan Foreman while under a psychic attack.
According to a second account, the "Decayed" Master was the result of the Thirteenth Master attempting to regenerate beyond the twelve-regeneration limit. (PROSE: Meet Missy!, The Doctor vs the Master)

According to a third account, the Thirteenth Master is attacked by the "Bald" Master on Tersurus, and left in a decaying state by an energy net. The Cult of the Heretic then switch the Masters' bodies, and the "Decayed" Master hires the Transhuman Sisters of the Unholy Protocol and the Dragonhunters to kill the "Bald" Master. After the Seventh Doctor switches the Masters back, the "Decayed" Master is put back on his path to The Deadly Assassin.
Set during The Two Masters, with the Master in the body of his future incarnation.
Having recently become a decayed husk, the Master allies with Goth to use the Eye of Harmony and the Sash of Rassilon to restore his body, but he is defeated by the Fourth Doctor.

Restored by the Tzun

After escaping Cheetah World to 1957 America, the "Tremas" Master makes contact with the Tzun Confederacy and arranges a deal between them that allows him to use their technology to give him a new regeneration cycle. After he is shot by Ace, the Master is able to regenerate into a new body and escapes by leaving a booby-trap for the Seventh Doctor in a nuclear warhead.

After living a peaceful life for ten years, the Master is offered a choice by Death.

Trial on Skaro

According to one account, the "Tremas" Master travels to Skaro in order to goad the Daleks into killing him, as part of his plan to steal the Doctor's body using a Deathworm Morphant.

Main article: Theory:Timeline - The Master (Bruce)

Fight for the Glory

As his essence is left wandering the Time Vortex after passing through the Eye of Harmony, the Master is saved by Esterath to take part in the fight for the Glory, and is resurrected into the body of a deceased vagrant after Bruce's body decays beyond recovery. The Master's connection to the TARDIS brings him to Wormwood, where he witnesses the Doctor's fight against the Threshold. (COMIC: The Glorious Dead)
The Master observes the Doctor combat Donald Stark.
Forming an alliance with Sato Katsura, the Master turns Earth into a dystopia to anger the Doctor into fighting him for the Glory. After besting the Doctor, the Master learns that the real contest was between Sato and the Doctor's companion, Kroton. When Kroton wins, he removes the Master's influence from the TARDIS and place the Master somewhere that he cannot escape, implied by later releases to be the Eye of Harmony.

Trapped in the Eye of Harmony

The Master speaks to an amnesiac Eighth Doctor through a screen in his TARDIS. The Master's face is described as "wise and whimsical, with hard eyes and a beard flecked with grey". These descriptors are lifted straight from PROSE: Scream of the Shalka, where they are used to describe the incarnation of the Master played by Derek Jacobi in that story. Likewise Justin Richards noted in DWM 338 that the conversation between the Doctor and Master here is intended to tie in with the events of Scream of the Shalka.

Richard and Violet walk home from the pub together, when Richard's eyes glow green revealing that he had been possessed by the Master the whole time. (PROSE: Forgotten)

Reaching the end

Following on from Forgotten, the Master survives by possessing various bodies until he is imprisoned in the UNIT Vault. Upon hypnotising UNIT officers Ruth Matheson and Charlie Sato, the Master retrieves his TARDIS and escapes from the Vault.
Set after The Keeper of Traken.[1] The Master has his TARDIS and recalls stealing multiple bodies, setting this after Mastermind. The Master spends several centuries ruling the Gloxian Empire.
The "Decayed" Master recognises the "Bruce" incarnation as one of his past bodies, setting this after Mastermind, and claims to have spent "millennia" in his decayed body.
Dying and at the end of his life, the Master recalls his time trapped in the Eye of Harmony and how he was drawn back in after his escape in Bruce's body, until he found a way to escape permanently, setting this after Mastermind. He is killed by the Ravenous, leading directly into Day of the Master.
The "Deathworm" Master is resurrected by the "Bruce" Master, the "War" Master and Missy, posing as CIA agents, who use CIA technology to grant him a whole new regeneration cycle. He regenerates into a new body, implied to the "Bald" Master.
