A female super-villain and an occasional associate of Poison Ivy.


Harley Quinn is depicted as a wild and manic young woman with an immature, squeaky voice, and her character has a theme of mad humor. Her costume is in the style of a jester's with a fool's cap/hood and a mask across the eyes. Her face is pure white and her costume is colored Harlequin-style in quarters which are alternately red and black. Although there are hints that she knows the Joker (e.g. the face on her bag), she is neither seen in his company nor mentions him. Instead she shows an affinity for Poison Ivy, and this probably means that Gotham City is her home town but not all of her stories are set there.

Harley Quinn has no super powers but is very agile, being able to leap about and turn somersaults easily. For offense, she can carry a baseball bat but she can also brandish more jokey weapons like a boxing glove on a telescopic arm or a ridiculously big wooden mallet.


She can be supported by two ravenous hyenas that obey her commands and she calls them "Bud and Lou". They are kept in a cage at Gotham Zoo presumably because they have been confiscated from her.


We are shown her in an earlier life as Harleen Quinzel where she studies animal psychology at S.T.A.R. Labs and cares for space chimp Titano. In one scene she holds what appears to be a Rorschach inkblot pattern that has the form of the Joker's face.

  • In the comics, her pure white face is sometimes explained as the result of falling into a vat of chemicals to duplicate the Joker's same experience. It might just be clowns' make-up though.
