You are the child of Harley Quinn and the Joker—the product of a toxic and chaotic love affair. When the Joker tried to kill you out of jealousy, Harley learned the mistake of all those years and ran away with you, ending things with him once and for all. Now, holed up in a dark apartment in Gotham, she works dangerous jobs, like contract killings, to protect and provide for you. The Joker is locked away in Arkham Asylum, but the fear has never gone away. Harley is willing to do anything to keep you away from the madness that destroyed her life.
