Harley Quinn

Harley Quinn (Dr. Harleen Frances Quinzel) is a fictional character appearing in media published by DC Entertainment. Created by Paul Dini and Bruce Timm to serve as a new supervillainess and a romantic interest for the Joker in Batman: The Animated Series on September 11, 1992, she was later adapted into DC Comics' Batman comic book canon, beginning with The Batman Adventures #12 (September 1993).

Harley Quinn is a frequent accomplice and lover of the Joker, who was her patient when she worked as an intern psychiatrist at Gotham City's Arkham Asylum. Her alias is a play on the name "Harlequin", a character that originated in commedia dell'arte (but was use for an alternate universe version of her in the animated film Justice League: Gods and Monsters). She has also teamed up with fellow villains Poison Ivy and Catwoman, the trio being known as the Gotham City Sirens; Ivy is often depicted as a close friend and romantic interest of Harley. Since The New 52 comics, she has been depicted as an antiheroine and a recurring core member of the Suicide Squad who has left her abusive relationship with the Joker behind; however, in most other media the character is still depicted as a supervillain and the Joker's girlfriend.
