Harley Quinn

Harley Quinn is a member of The Rogues and one of Batman's archenemies.

History
Meet Arkham Asylum’s newest psychiatrist! An intelligent and insightful doctor, Harleen Quinzel takes a keen interest in the asylum’s criminal inmates, paying especially close attention to her star patient, The Joker. With her devotion to her job and her surprisingly good understanding of the super-villainous psyche, she’s sure to accomplish a great breakout – er, breakthrough.

Mirthful, mischievous and just a little bit malevolent, Harley Quinn is The Joker’s number one sidekick/hench-person/fan. She’s endlessly loyal to her beloved Puddin’, making her the only one in all of Gotham City that he can fully count on to help with his sinisterly silly schemes. And if Harley can cause enough of a distraction for Batman that The Joker can get away? That’s all the better!

Description
Harley Quinn is one of the Joker's closest allies. She loves his silly pranks and nasty tricks. Her colorful costume and bright make up are nearly as eye-catching as the Joker's. Harley used to be a Doctor, but now she causes chaos. Batman should watch out for her swinging bat.
