A victim of the Bang Baby gas, Allie found an internet website that told her a cure was found for Bang Baby’s and that she’d have to travel to Gotham to get it. When she arrived, she found that Harley Quinn and Poison Ivy were behind the ruse. She reluctantly agreed to help them in their crimes, but when she found out that the “cure” didn’t exist, she attempted to kill them both. Static intervened and changed her mind and Harley and Ivy were carted off to Arkham.
Allie submitted herself for Bang Baby research to find a cure, which had recently received a large grant from Bruce Wayne.
