Harley Quinn's origin was also revised by A.J. Lieberman, when he came aboard the monthly title. Avoiding the complicated backdrop of Quinn's beginnings during the No Man's Land, Lieberman instead tied Quinn's origin closer to her animated series counterpart. Quinn helped the Joker escape
Arkham Asylum to pull of a heist at the First National
Bank, but was instead betrayed by
him and left behind to take the fall.
