The Black Mask Gang was the first gang formed by the Black Mask Roman Sionis. The gang was considered a deriviative of the Red Hood Gang as the villains used thematics and fought crime under a symbol. They represented this ideal by masking their face with a "black mask". Although initially the Black Mask Gang operated lowly, however, after the rise of the Batman and the battle of the Blackout, the gang got much more violent. Eventually Sionis disbanded the gang after being exposed as a mafia leader. With an obsession of mind control taking over, Sionis later founded a much more powerful gang, which was known as the False Face Society.
