About Jim Shooter
James Charles Shooter was an American writer, editor and publisher in the comics industry. Beginning his career writing for DC Comics at the age of 14, he had a successful but controversial run as editor-in-chief at Marvel Comics, and launched comics publishers Valiant, Defiant, and Broadway. Shooter and artist Curt Swan devised the first race between the Flash and Superman, two characters known for their superhuman speed, in "Superman's Race with the Flash!" in Superman #199 (Aug. 1967). Shooter wrote the first issue of Captain Action (Oct.-Nov. 1968), which was DC's first toy tie-in. With the quick turnover at the top, Shooter rapidly found himself rising in the ranks, and on the first working day of January 1978, he succeeded Archie Goodwin to become Marvel's ninth editor-in-chief. He also created the Superman villain Parasite in Action Comics #340 (Aug. 1966).
