Harley Quinn, originally appeared in the animated series Batman: The Animated Series, created by the duo Paul Dini and Bruce Timm in 1992. The positive reaction of the critics and audiences towards the character made her a constant presence in this animation and in the following Batman, until 1999 when she was also included in the DC universe of comics. Initially as a psychiatrist, then as a partner and romantic partner of the insane Joker, she became one of Batman\’s most iconic villains. Today she is portrayed more as an anti-heroine, acting to defend justice rather than a criminal.
