Bio: When renegade scientist Professor Milo used his "phobia liquid" to make Batman acutely afraid of bats and anything bat-shaped, the Caped Crusader temporarily assumed the identity of "Starman" to battle the villain. Basically, he used the usual Bat-Equipment redesigned into star-shaped paraphernalia. After the defeat of Milo, the bat-phobia faded away and Bruce Wayne returned to being Batman.
