The Doctor (Doctor Who)
The Doctor is the title character in the long-running BBC science fiction television programme "Doctor Who". Since the show's inception in 1963, the character has been portrayed by thirteen lead actors. In the programme, "the Doctor" is the alias assumed by a centuries-old alien—a Time Lord from the planet Gallifrey—who travels through space and time in the TARDIS, frequently with companions. The transition to each succeeding actor is explained within the show's narrative through the plot device of "regeneration", a biological function of the Time Lord race that allows a change of cellular structure and appearance with recovery following a potentially fatal injury.

Written by Robert Holmes, this story was planned as the 20th anniversary special. The 90-minute single-part story was commissioned on 2 August 1982 and would involve the various Doctors and companions drawn to the planet Maladoom where they are trapped by the Master who is working for the Cybermen. The Cybermen want to isolate the genetic material that permits Time Lords to time travel freely so that they can incorporate that information into their own biology. The First Doctor would be revealed as an android, hence the title being the "Six" Doctors. Holmes made little headway with the script and withdrew from the project on 13 October 1982. Holmes would later use part of the storyline in "The Two Doctors".
