M.O.D.O.K. (acronym for "Mobile Organism Designed Only for Killing") is a fictional character, a supervillain in the Marvel Comics universe. Created by Stan Lee and Jack
Kirby he first appeared in Tales of Suspense #
93 in 1967. Average technician George Tarleton found his fate forever changed thanks to a
random selection by his boss, the Scientist Supreme of A.I.M., who needed a unique, bio-engineered “living
computer” in order to plumb the mysteries of the Cosmic Cube. Tarleton was subjected to hideous experiments, mutating his body into a massive-headed being possessing superhuman intelligence and extraordinary psionic powers, the process drove him
mad. Given the code-
name M.O.D.O.K M.O.D.O.C. ("Mobile Organism Designed Only for Computing"), Tarleton instead turned on his superiors, slaying them all and declaring himself Scientist Supreme. Moreover, he changed his
name to M.O.D.O.K., with the “K” standing now for “Killing.”
