10. His Origin
M.O.D.O.K. made his grand debut battling Captain America in Tales of Suspense #93 in 1967. Originally, he was a simple lab technician called George Tarleton.
Tarleton was thrilled when he was hired by A.I.M. (Advanced Idea Mechanics) since he knew it was largest scientific organisation in the world. Sadly, Tarleton was oblivious that A.I.M. was run by terrorists. The organisation’s leader, the Scientist Supreme, believed he could conquer the world by harnessing the power of the Cosmic Cube: an artefact that could grant wishes.
To utilise the Cube's power correctly, the Scientist Supreme decided to turn an expendable employee into a living computer called M.O.D.O.C., which is an acronym for "Mental Organism Designed Only for Computing." According to A.I.M.'s leader, the experiment would force Tarleton's brain to go through a billion years of evolution in a matter of moments.
However, the mutagenic procedure didn't just make M.O.D.O.C. smarter; it granted him vast psionic powers. With a single psychic blast, he killed the Scientist Supreme and renamed himself M.O.D.O.K.; “Mental Organism Designed Only for Killing.” When the Scientist Supreme's lackeys realised M.O.D.O.K. was too powerful to defeat, he was made the leader of A.I.M. then and there.
