As the result of a violent undersea earthquake, the long-lost city of Atlantis reappears on the surface of the Atlantic Ocean. As the traveling Calico encounters the futuristic city, which appears devoid of all human life, they are captured by a tractor beam. Although they summon Godzilla to save them, the Kaiju King fails to do so and is abducted by a teleportation beam. The Calico is quickly destroyed after being taken into the city, but the crew escapes and explores the fantastic metroplex. They soon find the inhabitants of Atlantis, who are all in a form of suspended animation in a stasis chamber. Discovering a time travel device, Dr. Darian, and Brock are accidentally transported back in time thousands of years, just prior to the sinking of the great city. To escape death, they go into stasis with the rest of the population, and are discovered there by Pete, Capt. Majors, and Godzooky in the present. The youthful trio then discover the cause of the city's technology attackin
As a long dormant volcano in Alaska suddenly erupts, the crew of the Calico decides to investigate the phenomena. Suddenly, an enormous winged creature called the Firebird, since she literally thrives in super-heated lava and breathes fire, emerges from her resting place in the volcano (there is actually a legendary avian creature by that name in Russian mythology, though this fact is not alluded to in the show).

As Dr. Darian, Brock, and Godzooky travel underwater in the bathysphere, they are attacked by the source of the lightening bolt, the Megavolt Monster, an aquatic kaiju that resembles a giant electric eel. The monster severs the bathysphere's umbilical cord, and the craft ends up landing on an underwater desert that's protected by an air bubble. There the trio discovers an entire colony of Megavolt Monsters who acquire their electrical power by feeding off an electrolyzed outcropping of stone, which appears to be the mysterious power source that the crew first investigated. After battling the first Megavolt Monster to a standstill to save the Calico, Godzilla arrives at the underwater desert to save the bathysphere crew, and he penetrates the air bubble, causing the sea to rush in and de
