Soldier Boy is the name of three superhero characters in the comic book series Herogasm and The Boys, created by Garth Ennis and Darick Robertson. The first character introduced (but the third Soldier Boy in the timeline, with his two predecessors having died) is the elected leader of the Vought-American-sponsored superhero team Payback. He is depicted as one of the only "Supes" (i.e. "superpowered" or "superhuman" individuals, often acting as "superheroes") with selfless, benevolent motivations, who detests the use of profanity.
