Batman is a fictional superhero appearing in American comic books. Batman's secret identity is Bruce Wayne, an American billionaire, playboy, and owner of Wayne Enterprises. After witnessing the murder of his parents Thomas Wayne and Martha Wayne as a child, he swore revenge on criminals. He trains himself physically as well as mentally and crafts a bat-inspired personality to fight crime. Unlike most superheroes, Batman does not have any superpowers to his account and he rather relies on his genius brain, physical power, martial arts abilities, detective skills, science and technology, and his strong will. Batman became popular soon after his introduction in 1939 and gained his own comic book title, Batman, the following year. As the decades went on, changing interpretations of the character emerged.
