This is my favorite version of Modok by far you can find it & the artists other artwork Here
The Carcosa Modok Deluxe (acronym for Mobile Organism Designed Only for Killing) is actually a clone of the original that has come to the planet to begin the process for creating another cosmic cube. It has about 200 A.I.M. followers with it. This being is a 7th level psionic for determining his powers each day. The creature can telekinetically float 20" above the floor of its compound. It is a god to its A.I.M. followers! The monster has an interplanar battle station for itself & its followers. Its up to the Dungeon Master where he wishes to place this abomination on the face of Carcosa or else where.

According to wiki - George Tarleton is subjected to a mutagenic process that grants him superhuman intelligence, including a computer-like memory, the ability to scour and retain large databanks of information very quickly and solve abstract mathematical problems nearly instantaneously. He also has the ability to calculate the mathematical probability of any given event occurring; an ability so strong that it that borders on precognition. However, his creativity remains at average human level. As MODOK, the character also has psionic powers enabling him to mentally control both individuals and large groups, and generate force fields able to withstand minor nuclear explosions. Courtesy of AIM technology, MODOK wears a headband that enables him to focus his mental power into a devastating beam.
A side effect of the mutation was the growth of Tarleton's head to the point whereby his body can no longer support the weight, necessitating the use of an exoskeleton and hoverchair. The chair is equipped with a variety of weapons including missiles and lasers. Occasionally, Tarleton had the use of a giant humanoid vehicle that was proportionally sized to his head. Tarleton's organs also wear out quickly, necessitating the use of harvested clones, whose organs are used to sustain him.
As the leader of AIM, MODOK has advanced technology and a personal army at his disposal. You can read more about Modok Here
