Average technician George Tarletonfound 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, and the process drove him mad. Given the code-name MODOC ("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 MODOK, with the “K” standing now for “Killing.”
