Dr. Harleen Quinzel, alternatively known as Harley Quinn, was once a well respected psychologist at the Arkham Asylum who fell in love with The Joker and helped him escape from the facility. Succumbing to The Joker's manipulation she turned to villainous ways as The Joker's assistant. The Joker often took advantage of her skills in hand-to-hand combat weapons, usefulness in battle, combined with her physical agility, to have her commit nefarious deeds. She is mostly depicted as the Joker’s sidekick and right-hand woman. HHarley Quinn was created by Paul Dini and Bruce Timm, first appearing in Batman (1992 TV Series) Episode: Joker's Favor.
Her character was then introduced in DC Comics The Batman Adventures #12 (September 1993, non-canon)& Batman: Harley Quinn #1 (October 1999, canon)
