The Black Dragon Society is based on a real World War II organization of the same name; this society was not nearly as sinister as its comic book counterparts. Three different comics companies used the Black Dragon Society as villains in the 1940s: National Comics (DC Comics), Fawcett Comics, and Quality Comics. DC Comics came to own the other two companies, so all the different incarnations of the Black Dragon Society now belong to them. "All-Star Comics" #12 had "The Black Dragon Menace" in which a Japanese spy ring called the Black Dragon Society of Japan steals eight American inventions and kidnaps their inventors.
