In the second episode of the four-part story "The Face of Evil," the Doctor (Tom Baker) learns that the previously peaceful planet of the Sevateem has been split into two warring factions -- and that he, or one of his previous incarnations, is to blame. The Doctor also discovers the planet is being used as a personal "playground" by Xoanan, a rogue computer who is posing as a god. Originally broadcast January 8, 1977, "The Face of Evil, Episode 2" was written by Chris Boucher. ~ Hal Erickson, Rovi
