Spoilers are precisely defined here. Rules vary by the story's medium. Info from television stories can't be added here until after the top or bottom of the hour, British time, closest to the end credits roll on BBC One. Therefore, fans in the Americas who are sensitive to spoilers should avoid Tardis on Sundays until they've seen the episode.

Spoilers aren't cool here.
(Try The Howling, instead.)

This page lists appearances of the Master played by Roger Delgado 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.

By most accounts, this incarnation of the Master was separate from the Thirteenth Master who first met Goth on Tersurus, (COMIC: Doorway to Hell, AUDIO: The Two Masters, AUDIO: Sympathy for the Devil, Master Thief) however, by one account, it was this incarnation who was severely deformed shortly prior to his meeting with Goth. (PROSE: Legacy of the Daleks)
