The Hulk is trapped by an electric snare devised by Mr. Fantastic, Professor X and Tony Stark as a means of containing him. Before they can transfer the unconscious Hulk to the specially created coma-crypt, however, the Green Giant is teleported away by Psyklop who needs the Hulk's energy to revive his dormant people and conquer Earth.
Meanwhile, following up on a clue from a friend of the Falcon (who was rescued from a voodoo cult), the Avengers (Thor, Goliath, Iron Man, and Captain America) arrive on a Pacific atoll inhabited by giant monsters. The Avengers find the entrance to Psyklop's lair, where the insectoid villain is shrinking Hulk for easier study.
A battle ensues, distracting Psyklop from his efforts and Hulk is inadvertently shrunk to microscopic size and vanishes.
The angered Psyklop turns an energy beam on the Avengers which teleports them back to New York City and erases all memory of their encounter.
