Harley Quinn, previously referred to as Dr. Harleen Frances Quinzel, is a fictional character created by the comic book publisher, DC Comics. Unlike many characters, she first appeared in an animated series ("Batman: The Animated Series") and then in the comic book as opposed to the other way around.

We first encountered her as a psychiatrist working at Gotham City's Arkham Asylum, where one of her patients was the Joker. As time went on, she fell in love with him, broke him out of the asylum and later became his accomplice and occasional lover. 

She is known throughout the world for her infatuation with the Joker and her willingness to do anything for him. She is also shown to be bubbly, outgoing and friendly. Harley has often been said to have a demented mind, but she is also very intelligent. Her multiple personality traits make her one of the most unique and well-liked characters from DC Comics.

Everyone, whether it be a little or a lot, has something in common with this villainess, but the question is, how much do you share with her? Will you be so identical that you could be mistaken for her, or will you be so opposite that the only thing you share is that you are both human? Take this quiz to find out!
