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.

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)
