Collider argues that Deathstroke, played by Manu Bennett in *Arrow*, became one of DC television’s most effective villains through his violent and personal conflict with Oliver Queen. The article presents the character as Oliver’s defining adversary and notes that the television portrayal gave Deathstroke greater impact than his brief live-action film appearance in Zack Snyder’s DC films.

It also outlines Deathstroke’s comic-book background as Slade Wilson, a highly trained military veteran recruited for a government super-soldier experiment. The procedure gives him enhanced strength and healing abilities, but he leaves military service to become a mercenary assassin, setting him apart from more conventionally heroic super-soldier figures.
