Deathstroke

Deathstroke is a supervillain appearing in American comic books published by DC Comics. Created by writer Marv Wolfman and artist George Pérez, the character first appeared in The New Teen Titans #2 (1980) as Deathstroke the Terminator. Deathstroke is the alias of Slade Joseph Wilson, a mercenary and former U.S. Army soldier who gains enhanced physical and mental abilities from an experimental super-soldier serum. Regarded as the greatest and deadliest assassin in the DC Universe, he serves as the archenemy of Dick Grayson and the Teen Titans, although he has also fought other superheroes, including Grayson’s mentor Batman, Green Arrow, and the Justice League. Deathstroke's vendetta against the Titans began when he swore revenge for the death of his eldest son Grant; his other two children, Joseph and Rose, would go on to join the Titans to oppose him. A bicolored black-and-orange mask that covers his missing right eye serves as Deathstroke's visual motif. The character has been adapted in various media incarnations, having been portrayed in television by Michael Hogan in Smallville, Manu Bennett in Arrow, and Esai Morales in Titans; and in film by Joe Manganiello in Justice League and its director's cut. Ron Perlman and others have provided Deathstroke's voice in animation and video games.
