With the aid of Reed Richards and Charles Xavier, the military has managed to capture the Hulk with a specially device that incapacitates the brute. When the Hulk is finally knocked out, they intend on sealing him in a chamber that would constantly keep him sedated with coma inducing gases. With the Hulk finally knocked out, the military begins to move in and collect the unconscious monster.

Meanwhile, the Avengers Goliath, Iron Man, and Thor have joined Captain America and his partner the Falcon to an island out in the pacific. What brought them there was events that happened days earlier: When the Falcon becomes concerned about a friend who was due to come up and visit from New Orleans didn't show up. Traveling there, they happen to track down Sam's friend to a voodoo ceremony taking place deep in the swamps where the practitioners are showing worship to the Dark Gods. Fighting the Voodoo cult, they find that Sam's friend is among them and all he says over and over is the location of the island in latitude and longitude. Returning to New York the duo would recruit Cap's fellow Avengers to help them investigate, although Black Panther, Vision, Scarlet Witch and Quicksilver opt to stay behind to attend to other matters. On the island, the Avengers stumble upon a gigantic statue of some ancient demon.

While back in the United States, as Reed Richards prepares to put the Hulk into the specially made container, he is shocked to see the Hulk suddenly teleport away. The Hulk has been transported to a secret laboratory on the island the Avengers are exploring by a creature named Psyklop. Psyklop is an ancient insectoid race that existed before man and worships the Dark Gods and hopes to take over the world for them.

As the Avengers are faced with a strange monster on the surface, Psyklop prepares to shrink the Hulk down to size, hoping to use his body as a power source to summon the Dark Gods. The Avengers, having fought off the monster outside crash into the lab and begin fighting Psyklop. During the fight, the Hulk is left unattended and the shrink ray trained on him causes him to shrink so small that he vanishes from sight. Furious at losing the Hulk, Psyklop uses a teleportation device to send the Avengers back to New York. The group materializes in the middle of a subway with no memory of the battle they had just had.

The Hulk's fate continues in Incredible Hulk #140....
