Within a month, Black Mask had assembled a group of dozens of criminals called the False Face Society, using the Sionis crypt as their base of operations. Each member of the False Face Society wore a distinctive mask, and the gang's crime spree spread rapidly throughout Gotham, eventually attracting the attentions of the police and Bruce Wayne, now operating as the vigilante Batman. To settle old scores, Black Mask murdered three Wayne Foundation executives and kidnapped Circe, forcing her to don a mask laced with Janus Cosmetics' toxic makeup, sparing her life but permanently disfiguring her face. Black Mask then threatened Circe into rejoining him, giving her a "mannequin" mask intentionally designed to mock her former life.
