Peter Davison (in-universe)
From Tardis Wiki, the free Doctor Who reference
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 an alternate dimension where he found that his life existed as a TV show. 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 )
