Arsenal is the alter-ego of several characters in the DC Universe. It is most prominently used by Roy Harper, who took it after graduating from his role as Green Arrow's side-kick Speedy and dropped it when he became Red Arrow. Roy returned to his role after his daughter Lian was murdered during Justice League: Cry for Justice. He has been a member of the Titans, Checkmate, Suicide Squad, the Outsiders and the Outlaws. Harper first began using the name and costume of Arsenal in New Titans #99 (1993), by Marv Wolfman and Tom Grummett.
