The Man-Thing is a fictional character appearing in American comic books published by Marvel Comics. Created by writers Stan Lee, Roy Thomas, and Gerry Conway and artist Gray Morrow, the character first appeared in Savage Tales #1, and went on to be featured in various titles and in his own series, including Adventure into Fear. Steve Gerber's 39-issue run on the series is considered to be a cult classic.

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.
