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.
Doctor Who: Destiny of the Doctors
It is a matter of debate as to how the game fits into the continuity of "Doctor Who". There are references to the "seven complete incarnations of the Doctor", with no reference made to either the Eighth Doctor, despite the game being released some time after the 1996 TV movie. However, the TARDIS database does vaguely mention the Seventh Doctor's regeneration. It has been speculated that the Master's imprisonment at the end of the game is by the Daleks, which would then lead into the opening of the TV Movie. This could also explain the absence of any mention of the Eighth Doctor (if the events of the game are set before the TV Movie).
The bulk of the game takes place in the Doctor's TARDIS (and, on occasion, the Master's TARDIS, reached via "junctions" between the two time machines). The game begins in the Console Room of the Fourth Doctor's TARDIS, and the player must then select one of the Doctor's seven incarnations and activate the TARDIS to go in search of them.
