"The Stranger" Doctor

Paul was a male with amnesia. His species was unknown, but implied to be either human or Time Lord.

Within The Game of Rassilon
Paul was one of a selection of mostly extrra-canonical incarnations of the Doctor sent to a Babylon 5 convention to collect the pieces of a missing alien artifact.

Behind the Scenes

 * Paul was inspired by a character from a romance novel called "The Stranger", largely inspired by Paul McGann's performance as the Eighth Doctor in the 1996 TV movie.
 * This is the only other player character Melinda-Catherine Gross got to play before leaving the podcast.
