The Doctor (The Ultimate Adventure)

When the Third Doctor fell ill, he projected a Watcher-like incarnation whose existence created a divergent timeline. This incarnation of 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. (STAGE: The Ultimate Adventure)

Later, the Jason, Crystal, and Zog of his timeline were taken to be the Sixth Doctor's companions.
