Batman wears a dark black cape and a suit with a bat symbol on it. Also a mask to hide his identity. He has black shoes and black pants.
Batman is a hero because he has saved the world from many villains or just saves people like that little boy who nearly got run over by a train or the city with the dam that nearly exploded!
Batman has no powers so he saves the world with his strength and bravery and his tools like his Batmobile and his bat frisbee!
So in the end Batman strikes again by saves the world.
