The Hulk feels the unbreakable chains loosening up, as the tension triggers his transformation into Banner.
Right before the change, the Chameleon, who is a master of disguise and currently under the command of another villain called the Leader, disguises himself as Thunderbolt Ross. The Chameleon gives orders to the soldiers to leave the area.
As Banner, he easily frees from the large chains, and hides with the help of Rick Jones.
The Chameleon cannot find the monster, so he disguises as Bruce Banner, kidnaps Betty Ross, and threatens everyone with a gamma hand grenade.
Banner turns into the Hulk, rescues Betty and absorbs the bomb blast with his body. The Chameleon escapes in the confusion.
