MODOK

George Tarleton was a widely respected genius. He was one of earth’s greatest scientists on psionics. However, Tarleton often found himself doing Soviet dirty work. He was turned into an ugly floating head after volunteering to become a guinea pig for The Red Ghost’s. After they both fell for the same woman, The Red Ghost increased the test dosages, and MODOK’s body began to shrink whilst his head grew. Depending on a life support system to keep him alive, MODOK began working for The Mandarin, as he believed The Mandarin knew how to cure him.

Later believing The Mandarin was dead; MODOK began searching for his rings in order to gain his power. After they later collided over the possession of his rings, MODOK again became working for The Mandarin, only to later betray him, for creating the anti-technology filed that rendered his life support systems utterly useless. He sided with Iron Man, and Iron Man left him free to go as a reward for betraying his boss.

Trivia

 * MODOK stands for Mobile Organism Designed Only for Killing.
 * While most fans agree that all aspects of Iron Man are improved in season one, MODOK took a dip in quality as the animators completely forgot about his origin and instead has him claim that he sticks with Mandarin because “He Makes Me Laugh”.
 * Some fans speculate that the season two version of MODOK is gay.
