The Penguin or Oswald Chesterfield Cobblepot is a fictional supervillain appearing in American comic books published by DC Comics, commonly as an adversary of the superhero Batman. Artist Bob Kane and writer Bill Finger introduced the character in Detective Comics #58 (December 1941). The Penguin is one of Batman's most enduring enemies and belongs to the collective of adversaries that make up Batman's rogues gallery. The Penguin is depicted as being short and portly, and he is known for his love of birds and his specialized high-tech umbrellas. A mobster and thief, he fancies himself as being a "gentleman of crime"; his nightclub business provides a cover for criminal activity, which Batman sometimes uses as a source of criminal underworld information. According to Kane the character was inspired from the then advertising mascot of Kool cigarettes – a penguin with a top hat and cane. Finger thought the image of high-society gentlemen in tuxedos was reminiscent of emperor penguins. Unlike most of Batman's rogues gallery, the Penguin is in control of his actions and perfectly sane, features that help him maintain a unique relationship with the crime-fighter. His latest characterization has him running a nightclub and casino that is popular with the underworld. Batman comes to tolerate his operations so long as the Penguin remains one of his informants. The entrepreneurial Penguin often fences stolen property or arranges early prison furloughs for a hefty fee.
