Black Mask (Roman Sionis) is a fictional supervillain appearing in comic books published by DC Comics.[1] Created by Doug Moench and Tom Mandrake, the character debuted in Batman #386 (August 1985).[2] He is commonly depicted as a brutal and ruthless crime lord in Gotham City who has a fixation with masks and derives sadistic pleasure from the act of torture. Black Mask is one of the most enduring enemies of the superhero Batman and belongs to the collective of adversaries that make up his rogues gallery.[3] The character has been substantially adapted from the comics into various forms of media, including the cartoon show The Batman, the animated film Batman: Under the Red Hood, and the Batman: Arkham video game series. Black Mask made his live-action debut in the 2020 DC Extended Universe film Birds of Prey, portrayed by Ewan McGregor.[4][5] Black Mask appears in the second season of the Arrowverse series Batwoman portrayed by Peter Outerbridge.
