Appearance

Clothing

Behind the scenes
This incarnation of the Doctor is similar to the Curator, as well as the Doctor from the narration links of the 1992 VHS release of Shada, in the fact that they are all intended to be future incarnations of the Doctor and are all played by an older Tom Baker. Though whether they were intended to be one and the same is still unknown.
