Peter Davison (in-universe)

From Tardis Wiki, the free Doctor Who reference
You may be looking for the real Peter Davison.

Peter Davison was an actor that the Doctor once saved from a Krynoid. He thought that something seemed familiar about him.

The Eleventh Doctor once fell into a parallel universe where he found that his life existed as a TV show called Doctor Who. He was surprised to learn there that Peter Davison existed in that universe as well, and played his fifth incarnation on TV. (COMIC: The Girl Who Loved Doctor Who)
