The Monster Society of Evil is a supervillain team created by Otto Binder and C. C. Beck for Fawcett Comics. It is led by Mister Mind against their mutual enemy Captain Marvel. The team is significant as one of the first supervillain teams in comics to contain villains that a superhero had fought previously; prior to this, supervillain teams were composed of villains created just for that storyline. In fact, the Monster Society consists of every major enemy Captain Marvel had ever faced.
