Robot Body: When Modok employed this mechanism, his Strength and Fighting ranks were increased to Amazing. The body itself had the following characteristics:

The international law enforcement agency SHIELD planted its operative Sharon Carter within AIM as a double agent to learn what Modok was and what his weaknesses, if any, were. However, AIM discovered that Carter was serving SHIELD and made her a prisoner aboard the organization’s submarine headquarters. Captain America went there to rescue her but was captured himself. Both he and Carter were sent to Modok, who attempted to kill them. During Captain America’s battle with Modok, other AIM agents, who were opposed to Modok’s rule, fired a volley of shots that wounded Modok. Captain America and Carter escaped the submarine, which Modok then destroyed. However, Modok used his psionic abilities to save himself and reassert his leader ship over AIM.

Not only was Modok continually thwarted in his schemes by the many superpowered adversaries, but also, under his leadership AIM made no scientific breakthroughs comparable to the organization’s earlier creation of the Cosmic Cube and the Super Adaptoid. Instead, AIM had stag nated intellectually and creatively. Moreover, Modok failed to launch an attack on any major nation as leader of AIM.

Hence, dissatisfaction with Modok’s leadership grew increasingly strong and widespread within the organization. Following his defeat by the Yellow Claw, Modok was deposed as leader of AIM. How ever, he soon regained control of AIM’s operations on the West Coast and established a new base in New York City as well. In alliance with Deathbird, then an exile from the Shi’ar Empire, Modok led his AIM forces in an attack on AIM’s East Coast division. Still, a considerable portion of the AIM organization remained outside of Modok’s control. Modok did not realize that the members of AIM whom he believed were securely under his control were secretly conspiring with the other faction of AIM to destroy him.

Modok led his AIM forces in an attack against the rival AIM faction, but, to his surprise, both AIM groups joined forces and attacked him. Modok retreated, soon afterwards fighting AIM forces alongside the Hulk, but finally fled after battling the Hulk himself.

With Modok gone, all of AIM was finally reunited under new leader ship. The new leaders of AIM hired the team of mercenaries known as the Serpent Society to assassinate Modok to prevent him from posing any further threat to them.

Two of the Serpents, Bushmaster and Diamondback, discovered Modok aboard AIM’s abandoned and partially demolished submarine headquarters, interrupting his use of equipment on board to recharge his psycho-motor energies to last him for another year. Though weakened, Modok escaped, ultimately hiding in a warehouse at a shopping mall in Newbury, New Jersey. The Serpent Society tracked him down to the mall, and Captain America went there, too, having learned of the Serpent’s mission. Captain America found the weakened Modok as two of the Serpents, Cottonmouth and Death Adder, were tearing away at his flesh. Modok died even as Captain America was trying to help him.

The Serpent Society delivered Modok’s corpse back to AIM. Although Modok remained brain dead, they repaired the other dam age done to it and kept the rest of the body alive. AIM’s new scientist supreme intended to use Modok as a living computer, but AIM member Yorgon Tykkio sent Modok into battle against Iron Man, guiding him by remote control. Tykkio had altered Modok’s headband so that it could fire plasma blasts and so that Tykkio could transmit his own voice through it. Iron Man succeeded in battling Modok to a standstill, whereupon Tykkio, by remote control, caused Modok’s headband to fire plasma that ignited underground fuel lines, causing an explosion that, finally, annihilated Modok’s body.
