The Magnetic Monster rose from the ocean to feed on anything it could. It brought down a plane, but the Calico managed to save the survivor. The Magnetic Monster soon attacked an oil refinery in the Arctic and fed, but Godzilla arrived. Before the monster could be killed, however, an oil fire surrounded the Calico and threatened to destroy it. Godzilla was forced to retreat to save his friends while the Magnetic Monster disappeared to the sea.
Not long afterwards, the Magnetic Monster swallowed the mini-sub that Captain Majors and Brock were in as they tried to track the monster. It arrived on land again and this time Godzilla needed to destroy it to save his allies.
The two battled, and the Magnetic Monster began absorbing all the magnetic waves from the pole and began growing in size until it was much bigger than Godzilla, making it seem unstoppable until it reached the center of the ice pole where the magnetic forces were at their strongest. Not able to hold any more, the Magnetic Monster exploded, and the mini-sub was saved.
