The Doctor (Introduction to the Night)

A future incarnation of the Doctor after his "Paul McGann" incarnation lived in the TARDIS. In the TARDIS he once encountered a Dalek and a Krynoid. After this encounter, he introduced a "night of pure entertainment". (NOTVALID: Introduction to the Night)

Behind the scenes
This incarnation of the Doctor is similar to the Curator, as well as the Doctor from 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.
