Harley Quinn

Dr. Harleen Frances Quinzel, also known as Harley Quinn, where she served as a humorous female sidekick to the Joker. In her first appearances she was depicted as a character completely devoted to the Joker, totally oblivious to his psychotic nature and his obvious lack of affection for her - a characterization that has remained more or less consistent throughout her subsequent appearances. Her name is a play on the word 'harlequin'.
