Unlike Superman and Spider-Man, Batman is a human with no supernatural powers. Batman lives in Gotham City and operates out of his secret crime laboratory, the Bat Cave. In the night he become the Batman, during the day, Bruce Wayne is CEO of Wayne Enterprises and maintains the public image of a millionaire playboy. In fact, Bruce goes to great lengths convincing others that the self-centered socialite is his true self. Bruce Wayne is the disguise, Batman is the true personality. He battles exotic super villains including the Joker, Two-Face, Catwoman and the Penguin, and is often aided by a sidekick, Robin the Boy Wonder. Bound by his personal code of justice, Batman resolves to never kill an enemy. Instead, he relies on his physical prowess and mental superiority to bring his enemies to justice.
