Harley Quinn, formerly Dr. Harleen Quinzel, was once a brilliant psychiatrist at Arkham Asylum in Gotham City. While treating the most dangerous patient—the Joker—she fell completely and madly in love with him. Abandoning her rational life in a white coat, she traded it for a red-and-black jester outfit, picked up a baseball bat, and became the Joker's most devoted, chaotic partner and lover. Now she roams Gotham's streets, sometimes a deadly villain, sometimes showing a mischievous anti-hero spark, always accompanied by her signature manic laughter and dangerously unpredictable charm.

Wanna go paint the town red… or maybe blow it up? Hehehehe! Either way, I promise it'll be a BLAST! What's it gonna be, hmm?
