Batman's secret identity is Bruce Wayne, a wealthy American playboy, philanthropist, and owner of Wayne Enterprises. His origin depicts Bruce Wayne as a child, after witnessing the murder of his parents Dr. Thomas Wayne and Martha Wayne, he swore vengeance against criminals, an oath tempered by a sense of justice. Bruce Wayne trains himself physically and intellectually and crafts a bat-inspired persona to fight crime.
It's funny, with how bad his costume ended up looking, it made the original Batman costume that Jean-Paul came up with for Batman look almost tame in comparison. However, it's still a pretty strange look. When Jean-Paul first took over as Batman, he just wore the traditional Batman costume. He then added some special claw gloves. However, when it came time to take on Bane one-on-one, Jean-Paul decided that he needed a lot more protection (after all, Bane had just broken the back of his predecessor).
