Synopsis
Hulk has been captured by Annihilus. Both the Bruce Banner and Hulk personalities have been banished by Cerebral Inhibitor into a virtual reality, leaving the body mindless. The ruler of the Negative Zone wants something from the body to upgrade himself from the teenage (insectoid) body he currently inhabits.
Anni's scientist Dr Bultar has discovered that the relevant substance only exists while Banner is transforming into the Hulk. So he's calmed the body down into the Banner state, and is now giving it adrenaline to start the transformation. He detects the substance forming, analyses its makeup and creates a synthetic equivalent.
Now droid(?) servants painfully remove Annihilus' outer shell, and restrain him for the even more painful procedure to follow. Bultar bathes him in rays which cause him agony as they grow his body. Anni's lieutenant Blastaar is concerned that the process appears to be going too far. But Bultar explains that their leader wants a body superior to the 1 he had when previously full grown.
And at the end what steps forth is a hulking version of Annihilus, still without a carapace.
Pip the Troll has been watching all this. Now he sneaks down next to Hulk's head and removes the Cerebral Inhibitor. Immediately Hulk wakes up with his own personality, leaving Bruce stuck in the computer. But Blastaar blasts him out of the building, and Pip lies unconscious in the resulting rubble.
Annihilus has no use for Hulk anymore and gives Blastaar permission to kill him. Blasty calls his flight boots to him and sets off in pursuit. What follows is a flying vs leaping battle, with blasting vs throwing stuff. When Hulk gets the upper hand Blastaar is saved by a swarm of flying insectoids who attack with ray guns and claws - Annihilus' Royal Guard. But Hulk brushes them aside and it's back to fighting Blastaar again.
Meanwhile Annihilus is fitted with his new shell, augmented with biometric microcircuits. And Pip wakes up.
Hulk finally drops a building on Blastaar. Then turns to face the giant-size armoured Annihilus.
