3. Harley Quinn aka Harleen Quinzel
Sometimes it is possible to love something too much. Harley Quinn, Jokers right hand woman has been used and abused time and again by Mr. J. Her tragic love story began in Batman the Animated Series where the character was so popular that she was incorporated into the comic books, video games and was supposed to make an appearance in Joel Schumachers 3rd Batman film Batman Triumphant portrayed by Madonna. Thankfully that film was regulated to the garbage bins of Warner Brothers Studio next to Sean Youngs Catwoman outfit. The Joker used Harley to get into places he could not due to his recognizable face. When Harley eventually became tired of his antics she left him to form her own gang before teaming up with BFF Poison Ivy, because sisters commit crimes from themselves.
