Fanon:Batman (Not exactly, we changed some parts up or else we might get sued!)

"Batman is the superhero protector of Gotham City, a tortured, brooding vigilante dressed as a bat who fights against evil and strikes fear into the hearts of criminals everywhere. In his public identity he is Bruce Wayne, billionaire industrialist and notorious playboy. Although he has no superhuman abilities, he is one of the world's smartest men and greatest fighters. His physical prowess, technical ingenuity, and tactical thinking make him an incredibly dangerous opponent. He is also a founding member of the Justice League."
