Appearance
This incarnation dressed in contemporary 1980s clothes including a beige coat and trousers, a brown hat, and a Greenpeace t-shirt. It is not known which of his regenerations this Doctor was in.

Behind the Scenes

 * This incarnation of the Doctor was created when Jon Pertwee, who reprised his role as the Third Doctor in the stageplay, fell ill just before a performance on 29 April 1989. His understudy, David Banks, filled-in as the Doctor for the remaining two performances.  The play was further altered by Chris Beaumont taking Banks' normal role of Karl.
 * This Doctor has been informally dubbed the "Greenpeace Doctor" by fans, after his t-shirt.

Other appearances
This Doctor was later seen in a dream by Crystal, who believed her Doctor to have died. (ST: Face Value)
