George Tarleton was a leading scientist of A.I.M. who became the organic computer M.O.D.O.K. (Mental Organism Designed Only for Killing). Tarleton was born in Bangor, Maine and raised in Erie, Pennsylvania. He was a founding member of Advanced Idea Mechanics or A.I.M. for short. The CEO Aldrich Killian focused on biological enhancement, while Tarleton focused on technological advances. In 2010, he was recruited into Project Pegasus to research the Tesseract and find a way to tap into its infinite cosmic power, however, the project was rendered defunct in 2012. After Killian died and his acts of terrorism were exposed, Tarleton became the CEO of A.I.M. and spent years undoing the damage done by his former colleague. Tarleton redirected the focus of A.I.M. away from Killian's Extremis, and instead started a number of projects to put the organization back on track, including unlocking mental potential.

After the transformation, he was to be known as M.O.D.O.C. standing for Mental Organism Designed Only for Computing. He quickly eliminated his competitors for leadership over AIM, and became their full-time commander. He was then known as M.O.D.O.K.: Mental Organism Designed Only for Conquest. As leader of AIM, he has had confrontations with Captain AmericaIron Man, S.H.I.E.L.D. and the Avengers.

M.O.D.O.K has formed an alliance with Baron Helmut Zemo to achieve world conquest. He has since worked on many projects with Zemo.

Powers and Abilities

  • Super-intelligence
  • Psionic Powers:
    • Telekinetic Force Blasts
  • Ability to calculate probability that borders on clairvoyance.


  • Doomsday Chair: Due to M.O.D.O.K.'s mutated size, he is no longer capable of unassisted physical movement. M.O.D.O.K.'s body is housed within a technologically advanced device which he refers to as his "Doomsday Chair". The Doomsday Chair, in addition to providing structural support or M.O.D.O.K.'s frame, also magnifies his psionic capabilities to the Nth degree. Though primarily a self-sufficient device, the Doomsday Chair can also be connected to a special energy cradle that provides it with an endless supply of power. Empowering both the chair and the cradle requires massive amounts of energy.
  • M.O.D.O.K.'s humanoid body: A humanoid, giant-sized metallic body, built by more than 100 AIM scientists, that M.O.D.O.K. could operate by entering the empty "headpiece". The body was hard to damage and gave him superhuman strength. It also allowed him to shoot beams of energy from the fingertips, and flight using boot jets. It was big enough to hold Iron Man in one hand.
