Powers/Abilities: When connected to his "brain charging" machine, Mento was granted incredible psionic abilities which included telekinesis, teleportation, remote-viewing, and he was able to restructure matter; however, his powers only worked while the machine had power. After spending several years lying down connected to the machine, Mento was left so physically weak that he found himself paralyzed.



(Strange Tales I#78/2) - Theorizing that he could affect reality if the power of his brain was increased, Krupp built a machine that would generate more power in his brain, the only drawback being it would do it so slowly he had to be connected to the machine for years. Hiring a medical attendant to check him periodically and feed him intravenously, Krupp was finally able to animate a suit of armor after months of being connected to the machine.

    Three years later, Krupp passed another milestone when he was able to create an animal--a gorosaur--simply by thinking it into existence. Dubbing himself "Mento the Mighty," Krupp's ambitions grew to nothing less than world conquest.

    In his tenth year of being hooked to the machine, Mento was able to levitate a nearby bridge as the powers of his mind continued to increase. In his fifteenth year, Mento reduced the height of the population of a nearby city to 12 inches, then restored everyone to normal. No longer satisfied with small amusing tricks, Mento was now prepared to take over the world. Seeing the threat that Mento posed, his medical attendant picked up a stone block to wreck the machine, but Mento simply teleported him away to a small island in the South Pacific.

    Just as Mento was ready to begin his plans for world conquest, the machine short-circuited, causing him to lose his powers, and all the feats he made happen were undone. As Krupp tried in vain to get up to repair it, he found himself unable to move--all the years he lay immobile had caused his muscles to atrophy, leaving him as helpless as a newborn infant, his plans for world domination were thus ended.

Profile by John Kaminski

Mento has no known connections to:

The Gorosaur

Standing about eight feet tall, the gorosaur (half-gorilla/half-dinosaur) was a creature that Mento willed into existence. When Mento's "brain charging" machine short-circuited and lost power, the gorosaur faded away.
