When it comes to supervillains, a comic fan’s mind might jump to the likes of the Joker, Lex Luthor, or the Green Goblin. But amongst the countless Golden Age villains is one brilliant but tiny worm: Mister Mind.

The two-inch alien worm was created for Fawcett Comics’ Captain Marvel Adventures series by Otto Binder and C.C. Beck. Though various versions of the character have appeared over the multiple Captain Marvel and Shazam! series by Fawcett and DC, the character’s powers tend to always include telepathy and extremely high intelligence.

Mister Mind is perhaps best known for leading the Monster Society of Evil, through which he carries out his plans. Members of the Monster Society of Evil have included the likes of Black Adam, King Kull, Mister Atom, and Oggar. Though most of his plots are foiled by Captain Marvel, he has also faced off against the likes of Booster Gold, and other members of the Justice League.

Featured in the upcoming Hake’s auction is a piece of original art by C.C. Beck of Mister Mind himself. The art, which is colored, features a full-body image of the worm with the words “Hee Heee Haww!” coming from the voice box around his neck. At the bottom, there is hand lettered text from Beck that reads, “Mr. Mind – My All-Time Favorite Villain!” along with Beck’s signature. Mister Mind is rarely seen in art like this, as Beck more commonly drew Captain Marvel himself, or other members of the Marvel family.
