Roy William Thomas Jr. is an American comic book writer and editor. He was Stan Lee's first successor as editor-in-chief of Marvel Comics and possibly best known for introducing the pulp magazine hero Conan the Barbarian to American comics. Thomas is also known for his championing of Golden Age comic-book heroes – particularly the 1940s superhero team the Justice Society of America – and for lengthy writing stints on Marvel's X-Men and The Avengers, and DC Comics' All-Star Squadron, among other titles.

Stan Lee was an American comic book writer, editor, publisher and producer. He rose through the ranks of a family-run business called Timely Comics which would later become Marvel Comics. He was Marvel's primary creative leader for two decades, leading its expansion from a small division of a publishing house to a multimedia corporation that dominated the comics and film industries.
