Tom Baker (in-universe)

Tom Baker was an actor in an alternate dimension where the Doctor's life was a TV show called Doctor Who. He played the Fourth Doctor in the show. On 12 October 1979, the Eighth Doctor accidentally slipped into this reality, Baker was a crucial part of foiling the plans of Beep the Meep, who had crossed into the universe before them and was controlling the minds of those inside the BBC Television Centre. By simply babbling in front of Beep, Baker was able to annoy him and bring back enough memories of his enemy the Fourth Doctor to destroy his plan. (COMIC: TV Action!)
