Harley Quinn – The Joker

Another side kick who busted out of their original stories and on to their own is Harley Quinn, former psychiatrist, desperately in love with the Joker, and absolutely insane. Harley Quinn was first introduced to the world via Batman: The Animated Series to fill some plot holes. She later appeared in a graphic novel, Mad Love, that sealed the deal. She was a fan favorite. Making her first movie appearance this year in Suicide Squad (portrayed by Margot Robbie) Harley Quinn is officially her own villain, one that stands up on her own, and one that we all absolutely adore.
