The Master (Scream of the Shalka)

An incarnation of the Master travelled with the Ninth Doctor in an android body.

Biography
At one point, the Master and the Doctor crossed paths. It was during this encounter that the Master lost his physical form, and he was forced to occupy an android body, the appearance of which he had personally selected. (NOTVALID: Scream of the Shalka) He noted that he was less than happy with this arrangement, saying that it was "an offer I was foolish enough to accept". He also said that he "was of aid to the Doctor during the events that damaged him". He could not leave the TARDIS because his android body was limited to functioning inside it. (NOTVALID: Scream of the Shalka)

He assisted the Doctor and Alison Cheney in fighting the Shalka. (NOTVALID: Scream of the Shalka, Scream of the Shalka)

The Master was later connected to the TARDIS' telepathic circuits by the Doctor in order to destroy a psychic vampire by feeding it with the Master's pure evil memories and personality. (NOTVALID: The Feast of the Stone)

Personality
This Master retained his charm and his wit, together with his hypnotic abilities. He attempted without success to hypnotise the Doctor's latest companion Alison Cheney, but was interrupted by the Doctor. (NOTVALID: Scream of the Shalka)

Behind the scenes

 * Derek Jacobi, who voiced this version of the Master, would also later play in Utopia and The War Master.
 * According to the production information text on the Scream of the Shalka DVD, in original drafts of the script, instead of an android of the Master being the TARDIS Defence System, it was going to be a hologram of the Fifth Doctor. This was later changed so that it would be the Master instead.
