The Doctor (The Ultimate Adventure)

The Doctor met his companion Jason in his native Revolutionary era France in 1789, having narrowly saved him from the guillotine. Later, they travelled to London in the 1980s where they met Crystal and, later, Zog. Together, they fought the Daleks and the Cybermen. (NOTVALID: The Ultimate Adventure)

In a different continuity in which Crystal had instead travelled with the Sixth Doctor, she saw this version of the Doctor in a dream prompted by her belief that the Sixth had died. (PROSE: Face Value)

Behind the scenes

 * This incarnation of the Doctor was created when Jon Pertwee, who reprised his role as the Third Doctor in the stage play, fell ill just before a performance on 29 April 1989. His, David Banks filled in as the Doctor for the remaining two performances. Another actor, Chris Beaumont took over Banks's usual role of Karl.
 * This Doctor has been informally dubbed the "Greenpeace Doctor" by fans, after his T-shirt.
