Batman is a fictional superhero who appears in DC Comics, as well as in a number of movie, television and video game adaptations. Unlike most superheroes, he does not possess any superpowers; he makes use of intellect, detective skills, science and technology, wealth, physical prowess, martial arts skills, an indomitable will, provocation of fear, and intimidation in his continuous war on crime.
Batman's secret identity is Bruce Wayne, an American billionaire, industrialist, and philanthropist. Having witnessed the murder of his parents as a child, he swore revenge on criminals, an oath tempered with a sense of justice. Wayne trains himself both physically and intellectually and dons a bat-themed costume to fight crime. Batman operates in the fictional Gotham City, assisted by various supporting characters including his butler Alfred Pennyworth, his crime-fighting partner Robin, the police commissioner Jim Gordon and occasionally the heroine Batgirl. He fights a large assortment of villains, often referred to as the "rogues gallery," which includes the Joker, the Penguin, the Riddler, Catwoman, Mr Freeze, Two-Face, Scarecrow and Poison Ivy.
