Harley Quinn (a.k.a Dr. Harleen Frances Quinzel) is a fictional supervillain character appearing in the DC Comics universe. That character was created by Paul Dini and Bruce Timm. She first debuted in Batman: The Animated Series back in September 1992 and was voiced by actress Arleen Sorkin. Dr. Harleen Frances Quinzel, her alter ego, is a psychologist that works at Gotham City's Arkham Asylum. She falls in love with the Joker and inevitably becomes his accomplice and on-and-off love interest/girlfriend. She follows in the Joker's clown-themed, criminal antics and adopts the name, Harley Quinn. It's a play on the name "Harlequin", a character which originated in commedia dell'arte.

Outside of Batman and Joker, Harley Quinn has teamed up with other villains such as Catwoman and Poison Ivy on many occasions. The trio is known as the Gotham City Sirens. Poison Ivy, in particular, is a close friend and ally of hers and is even depicted as her girlfriend in some comic book stories. After appearing in the Batman: Animated Series and various appearances, Harley Quinn finally gets her own animated TV show.
