Synopsis by Hal Erickson
In the conclusion of the six-part story "The Time Monster," those eternal enemies the Doctor (Jon Pertwee) and The Master (Roger Delgado) are forced to rely upon each other to survive the rampaging "time-eater" Kronos the Kronavore. In a final showdown, the two TARDISes owned by the rival Time Lords are trapped in a nebulous void with the triumphant Kronos determining the fate of all concerned. Whether or not the story ends happily is entirely in the eye of the beholder. Written by Robert Sloman, Doctor Who: The Time Monster, Episode 6 originally aired on June 24, 1972, as the final episode of Doctor Who's ninth season.
