Batman is a superhero appearing in comic books published by DC Comics. The character was created by artist Bob Kane and writer Bill Finger, and first appeared in Detective Comics #27 (May 1939). Originally named “the Bat-Man”, the character is also referred to by such epithets as “the Caped Crusader”, “the Dark Knight”, and “the World’s Greatest Detective”.
Batman’s secret identity is Bruce Wayne, an American billionaire, business magnate, 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 Batman’s “rogues gallery”, which includes the Joker, the Penguin, Two-Face, the Riddler, Catwoman, Mr. Freeze, Ra’s al Ghul, Poison Ivy, Scarecrow, and Bane. Unlike most superheroes, Batman does not possess any superpowers; he makes use of intellect, martial arts skills, physical prowess, detective skills, science and technology, wealth, provocation of fear and intimidation, and an indomitable will in his continuous war on crime.
Batman is a founding member of the Justice League and the Outsiders. He is part of DC’s “Trinity”, along with Superman and Wonder Woman. He’s ranked numerous times at #2 in the Top Comic Book Hero of All Time list. He has even intrigued psychiatrists with trying to understand his psyche.
