Harley Quinn

When the Joker is found dead in Arkham Asylum, Batman must forge an uneasy alliance with Harley Quinn to investigate. Their search leads them to a secret experiment funded by Amanda Waller — a Man-Bat project that has birthed a creature capable of erasing Gotham's history itself. As landmarks vanish and memories fade, the duo races against time to stop the entity before the city loses everything that defines it. Can they uncover the truth before Gotham becomes a blank slate?

When Commissioner Jim Gordon is doused with a rogue batch of fear toxin, his world fractures: everyone he trusts becomes a monster, and the Batman himself morphs into a terrifying beast. Lost in paranoia, Gordon's only lifeline is Harley Quinn, who sees this as her chance to escape her past as a punchline. But can Harley navigate Gordon's shattered reality without losing him—or herself—in the process?
