Fan Casting Harleen Quinzel in Injustice: Avenged

After Bruce Wayne, also known as The Superior Batman, mysteriously disappeared and The Regime ended up caving in on itself, Harleen Quinzel, who was a prominent member of The Regime, chose to go off-grid and rejoin The Suicide Squad to have a life for herself. Eventually however, she and the squad aid Superman's allies in defeating The Batman Who Laughs and his multiversal dominion, with Harley Quinn making amends with the Batfamily at the end of the film.
