The Leader has Bruce Banner, Doc Samson, General Ross and Spad McCracken as his prisoners. He laughs maliciously as he details the events that led to his resurrection. When last the Hulk encountered the Leader, it was as a pawn of the alien planet master known as Kurrgo. The Leader was believed killed during the episode, but he used his Electro-wave matter transporter to teleport to a safe haven. The experience paralyzed him however, and he had to use his enhanced intellect to purge the gamma mutation from his body. As normal Sam Sterns, he was able to overcome the paralysis until such time that he could expose himself to a second dose of radiation, transforming him back into the Leader.

As the Leader continues to gloat, Doc Samson manages to break free of his bonds. He rushes towards the Leader, but a post-hypnotic suggestion prevents him from actually attacking him. The Leader slaps Samson across the face to demonstrate how weak he is.
Suddenly, the Leader discovers that Clay Quartermain's jet is approaching Gamma Base. Seeing Quartermain as a potential reservoir of top secret S.H.I.E.L.D. secrets, the Leader leaves the room and heads towards the airfield.
Because of the Leader's mental override, Samson is unable to leave the base. However, he can free Ross and Banner from their chains. Samson realizes that only the primitive mind of the Hulk can hope to overcome the Leader's mental powers. Banner though, refuses to become the Hulk again. Another option presents itself. They decide to make use of a remote controlled Hulk robot.

Outside, the mind-controlled army personnel surround Clay Quartermain's jet. Clay is escorted into General Ross' office, where the Leader uses his abilities to paralyze him as well. Suddenly, the Hulk robot blasts through the wall and begins chasing the Leader. The Leader cannot understand why Banner would intentionally expose himself to gamma radiation once again. He races out to the hanger where he climbs aboard his Murder Module.

The Hulk gives chase and effortlessly plows through a squad of armed soldiers. The Murder Module straddles overtop of him and begins kicking at the Hulk. The Hulk leaps onto the control cabin and begins pounding at the glass. The Leader pushes a button and a wave of electrical energy shakes the Hulk free, sending him plummeting to the ground where he smashes into a dozen pieces. The Leader now realizes that his opponent was a robot and begins blasting at the scattered remains with his Module's death-ray.
Unfortunately, the destruction of the robot generated a great amount of electric feedback, which surged back into the control harness, greatly injuring Bruce. Samson rushes to his side and shockingly laments, "Bruce Banner is dying!"
