Black Mask

Roman Sionis, a former business executive who originally hated Bruce Wayne rather than Batman, wears a black wooden mask and leads the cult-like society of False Facers. Black Mask eventually became a mob boss controlling large sections of Gotham City's criminal underworld. Following the suspicious death of his multi-millionaire parents, Sionis had inherited their fortune and went on to bankrupt their company. Saved by a buyout by Bruce Wayne, Sionis came to resent and hate Wayne. Fixated on the concept of masks, Sionis carved one from his father's black coffin and sought revenge; his ensuing battle with the Dark Knight caused his mask to be burned into his skin, remaking him as the Black Mask. Sionis is now a feared gang leader and one of the most powerful mob bosses in Gotham, with a burning hatred for Batman.
