Mister Mind is a supervillain appearing in American comic books published by DC Comics. Created by Otto Binder and C. C. Beck for Fawcett Comics, he made a cameo appearance in Captain Marvel Adventures #22 (March 1943) before making his full first appearance in Captain Marvel Adventures #26 (August 1943). One of Captain Marvel's greatest enemies, Mister Mind is a two-inch alien caterpillar of high intelligence with telepathic powers who usually carries out his villainous plans through an organization called the Monster Society of Evil. The Monster Society of Evil made its debut in Captain Marvel Adventures #22, and the resulting "Monster Society of Evil" story arc continued for two years in Captain Marvel Adventures, ending with issue #46 (May 1945).
