Hulk, who calls himself Doc GreenHulk, who calls himself Doc Green now (calling him Hulk makes him, em, angry), is convinced that he must de-power A-Bomb, and the other gamma spawned creatures, because they all represent extremely dangerous unstable weapons.
His first target is A-Bomb, AKA Rick JonesHis first target is A-Bomb, AKA Rick Jones, his old-time friend. A-Bomb does not want to be de-powered, and fights the Hulk's off. A-Bomb tries reasoning with his green pal that he uses his powers for good and that they were a gift from M.O.D.O.K.
But the Hulk insists that such is but a curse. M.O.D.O.K. may have left a backdoor with which to control A-Bomb, and so he is determined to "save" his friend. The Hulk finally sticks a special needle in A-Bomb's chest and delivers his cure serum: Made from the Hulk's own blood, it includes adamantium nanomites that absorb Gamma energy. The serum works and A-Bomb turns back into Rick Jones.
The Hulk asks Rick for his aid in curing Betty Ross. Although they just fought and Rick is now Gamma powerless, he agrees to help.
The Hulk then gets to M.O.D.O.K., who created A-Bomb. The former villain is now working for SHIELD. M.O.D.O.K. admits to SHIELD of his responsibility for creating A-Bomb, and swears to stay away from any such experiments.
Learning about the news, Thunderbolt Ross, AKA the Red Hulk, states that he will bring the fight to the Hulk, and remain the sole Hulk among them.
