After a fight with Godzilla, a caterpillar-like monster transforms into him and begins to destroy anything connected to electricity. The gang's friendship with Godzilla is put to the test as they try to prove his innocence.

The gang happens across the ancient City of Atlantis and they (including Godzilla) end up imprisoned in the city. They soon discover that all the cities residents are under a spell that can only be broken by destroying the giant robot guarding the city.

After their ship is damaged in a storm, the team ends up on an uncharted island. They soon discover the island is inhabited by a cyclops monster. Worst of all, Godzilla cannot reach them because of a force field guarding the island. The team must escape the island and somehow not let the creature escape and threaten the world.
