Roy Harper is a fictional superhero appearing in American comic books published by DC Comics. Roy is one of DC’s most longstanding characters, originating in 1940s comics as Speedy, the teen sidekick of the superhero Green Arrow. Like his mentor Green Arrow, Roy is a world-class archer and athlete who uses his exceptional marksmanship to fight crime. Along with other prominent DC Comics superhero sidekicks, he goes on to become a core member of the superhero group the Teen Titans. As an adult, Roy casts off his Speedy identity to establish himself as the superhero Arsenal, and for a time adopts the name Red Arrow to symbolise his having become an equal of Green Arrow. In addition to continuing to serve on occasion as one of the Titans, Roy has had leading roles in the superhero groups the Seven Soldiers of Victory, the Outsiders, the Justice League, and the Outlaws.
