Batman (Earth-33⅓)

Batman was the name used by an incarnation of the Doctor.

Batman worked alone as a superhero for a time in New York City. After the Fifth Doctor landed his TARDIS on Madison Avenue and left it unlocked, Batman entered with an array of other superheroes that included Spider-Man and Superman. He encountered the Doctor upon his return to his ship who angrily proclaimed that the experience had taught him never to land in the city during a crimewave. (NOTVALID: Doctor Who? 64)

Batman later auditioned for his own titular role in the Doctor Who Movie along with several other candidates including a bewildered Seventh Doctor. According to him, the Cybermen had taken over Gotham City. As the first course of action he instructed an unseen Ace to hurry to the who-poles so they could both help defeat the invasion.
