[3] 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.

After a brief appearance in issue #26, Mister Mind is eventually revealed in Captain Marvel Adventures #27 to be a cartoonish alien worm with spectacles and a talkbox around his neck to amplify his voice.

[6] Despite his small size, Mister Mind continues to use his powers of intellect and telepathy to battle Captain Marvel in subsequent chapters of the serial, eventually recruiting numerous other allies ranging from Alligator-Men to Adolf Hitler and Benito Mussolini.

"The Monster Society of Evil" serial concluded with Captain Marvel Adventures #46 (1945), in which Mind is finally captured, tried, and executed for crimes against humanity at the Nuremberg trials.

Mister Mind would appear regularly as part of Captain Marvel's rogues gallery in his adventures in Shazam and World's Finest Comics through the 1970s and early 1980s.

#13 (March 1996), now a more realistically depicted caterpillar-like being from the planet Venus possessing powers which include mind control, telepathy, and mental image projection.

This Mind was the main villain of the second major story arc of The Power of Shazam!, and was depicted as the lead scout of Venusian worms looking to conquer the Earth.

While Captain Marvel eventually destroys the other worms, Mind survives and becomes a recurring villain in The Power of Shazam!, JSA, and other DC publications, often forming a Monster Society of Evil to do his bidding as in the original serial.

In this story, he gains the ability to evolve into a gigantic "Hyperfly", able to eat space and time and inadvertently creating a new DC Multiverse in the process.

Mister Mind came to Earth during World War II, drawn by its radio broadcasts; he especially loved Edgar Bergen's dummy Charlie McCarthy.

[8] As a side-effect of the reality-altering Crisis on Infinite Earths, Mister Mind arrived in the universe of Earth-S (where Fawcett's former characters dwelled) sometime around 1846 (it was mentioned in this story that he had been working on a weapon for 97 years).

His brilliant intellect, telepathic powers, and ruthlessness allowed him to conquer much of space, establishing bases on many different worlds as well as varied locations on Earth.

He recruited supervillains, armies, and entire alien species to aid him in his attempt to conquer the Earth, and first relayed his information from the planetoid Punkus via radio.

Finally, a desperate Mister Mind attacked Captain Marvel's alter ego Billy Batson with ether and left him unconscious.

Shortly after Captain Marvel's own return from suspended animation, he encountered Mister Mind trying to destroy the country with an expanding balloon-like weapon in St. Louis.

In the Elseworlds story Superman & Batman: World's Funnest (November 2000), the two near-omnipotent imps Mister Mxyzptlk and Bat-Mite engage in a tremendous duel that destroys many planes of reality.

Mind was one of a race of mind-controlling worms from the planet Venus, who had plans to invade and take over the Earth, which they claim to have once ruled around the Ice Age.

Appointed as the go-ahead agent, Mind arrived on Earth during World War II, by means of an indestructible space suit, but was captured by Bulletman, Starman, and Abin Sur before enacting his plan.

As Sivana is dragged off, Mind observes a televised memorial for the heroes lost in the Infinite Crisis, and takes particular note of Skeets, the robotic companion of the time-traveling superhero Booster Gold.

[12] With his metamorphosis beginning, Mind proceeds to weave a cocoon around himself, which doubles as a matter transporter that he uses to beam himself inside Skeets in Will Magnus' lab,[13][14] intending to use the robot as a "cradle" where he can spend the following year gestating and completing his transformation.

Destroying Skeets from within, Mind adopts his identity and makes plans to consume the Multiverse, which had returned to existence as a result of Infinite Crisis.

At the end of the year, Mind tracks Hunter and Booster down to the lab of T. O. Morrow, intent on acquiring the head of the Red Tornado, whose computerized brain has mapped the Multiverse.

[19] Also during the series, unrelated to Mind's activities, a new incarnation of the Monster Society was formed, consisting of the Four Horsemen of Apokolips, creatures engineered by Intergang's Science Squad (including Sivana).

miniseries, in the works since 2003, is a more traditional take on the character, returning Captain Marvel to his roots with a story set outside of the DC Universe.

In this version, Mister Mind resembles a small snake, with a more threatening face sans glasses, while wearing a modern style communicator headset.

[28] He briefly reaches maturity and evolves into a Hyperfly that manipulates reality, feeds on the timelines of singular universes, and traverses space, including dimensions with relative ease.
