The Penguin (born Oswald Chesterfield Cobblepot) is a DC Comics supervillain, antagonist, and one of Batman's oldest, most persistent enemies. The Penguin was introduced by artist Bob Kane and writer Bill Finger, making his debut in Detective Comics #58 (December 1941).

The Penguin is a short, round man known for his love of birds and his specialized high-tech umbrellas. A mobster and thief, he fancies himself a "gentleman of crime;" his nightclub business provides a cover for more low-key criminal activity, which Batman tolerates as a source of criminal underworld information.

He appeared in "When You Wish Upon a Weinstein", outside the bus of the Brides of Christ, chuckling and clearly eager for the punishments that the nuns were about to bring upon their target.
