Season 1

As a long dormant volcano in Alaska suddenly erupts, the crew of the Calico decides to investigate the phenomena.

As the Calico investigates a strange electromagnetic power source beneath the sea near the Bali Trench, an oil tanker is sunk by what appears to be a bolt of lightening that originates underwater. 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

San Francisco is threatened as a bizarre, quadrapedal multi-colored subterranean monster appears underneath the city. The creature is called the Eartheater, since it lives by devouring huge amounts of rock, soil, and steel, wreaking much havoc in the process by causing buildings and other man-made structures to collapse; the Eartheater also projects waves of sonic force from two antennae on top of its head to help it dig, but which can also be utilized as a formidable weapon in battle. As the crew of the Calico travel into the underground tunnels created by the Eartheater to investigate, they're trapped by the creature. Calling on Godzilla for assistance, the Big G rescues the Calico crew and drives the Eartheater above ground during the ensuing battle. As the earth-devouring monster climbs the Golden Gate Bridge to escape, Godzilla knocks the creature off of the structure with his laser beams. Landing in the water, the Eartheater discovers his fatal weakness as he dissolves into mu

After discovering the ancient hidden pyramid of Ra-Mal in Egypt, an archeologist named Jarvis is suddenly besieged by two giant, quadrapedal sphinx-like monsters made of stone, who attack the hapless scientist with waves of freezing winds from their mouths. As the crew of the Calico docks in a small town near the Nile River, they come across the severely frostbitten Jarvis, whom they nurse back to health. Jarvis then describes his ordeal to the crew, explaining that the Stone Creatures are mystical guardians of the pyramid who will attack anyone or anything that dares approach it. Naturally, the Calico crew decides to investigate, and they fly their mini-copter to the area, only to be attacked by the Stone Creatures themselves. They call upon Godzilla, who engages the rocky beasts in battle, at one point being frozen solid by the combined might of both the creatures' cold blasts. Godzilla finally defeats the Stone Creatures when the two rocky monsters charge him simultaneously, a

While diving in the sea near the West Indies, Dr. Darian and Brock are startled when they are attacked by a bizarre mutant life form...a creature composed entirely of seaweed, which continues to grow increasingly larger as the plant beast merges with more and more seaweed. The two divers barely escape the plant creature's two huge tendrils as they frantically swim back to the Calico. There they call upon Godzilla to deal with the creature, and while the Seaweed Monster is no match for Godzilla, the Kaiju King can't seem to severely injure the plant creature's physical substance. As the Seaweed Monster menaces a nearby inhabited island, Dr. Darian notices that a severed piece of the creature completely dried up after excessive exposure to sunlight. Thus, she directs Godzilla to drag the Seaweed Monster onto land, where the searing tropical sunlight eventually causes the plant creature to wither and die.

A long time ago, a friendly alien race deposited a gigantic Cyclops on an uninhabited island for unknown reasons (the creature actually resembled a one-eyed cross between a human being and a crustacean, rather than the much more humanoid Cyclopes of Greco-Roman mythology), but they constructed a force field around the entire island to protect the people of Earth from the creature. However, the force field is accidentally de-activated during a freak magnetic storm, and the Calico docks on the island to repair damages that occurred during the storm. The force field soon re-activates, and the crew find themselves trapped on the island and menaced by the Cyclops. Although they call Godzilla, the King of the Monsters is unable to penetrate the force field to come to the crew's rescue. Dr. Darian discovers a stone monolith on the island that controls the force field, and she de-activates it, thus allowing Godzilla to enter the island and battle the Cyclops. Although the one-eyed kaiju

After a meteor falls to Earth, an investigating man finds nothing there but a mysteriously glowing tree. After he leaves, the ‘tree' reverts to its true form, an alien beast that resembles a giant centipede. Requiring large amounts of energy to survive, the Energy Beast attacks the Mesa City Dam, absorbing energy from its hydroelectric turbines, and growing much larger in the process. Since the Calico crew is (conveniently) in Mesa City at the time, they summon Godzilla, who drives off the alien Energy Beast, but the former appears to have been injured in the process. A short time later, a mysteriously glowing Godzilla attacks an electrical power plant, and fails to respond to either the crew's signal, or Godzooky's call. This leads the crew to suspect that Godzilla either went mad after his encounter with the Energy Beast and became such a creature himself, or that there is somehow more than one Godzilla (actually, any 6 year old with half a brain immediately figured out what was real

A drilling outpost in Antarctica is attacked by an enormous amphibious sea creature that resembles a giant sea turtle who rises from the depths of the Antarctic Ocean, and the monster absorbs the energy from the facility's oil pump. The creature is dubbed the Magnetic Monster, since it has the power to generate waves of magnetic force from its beak that can either attract or repel objects, and it needs to feed on magnetic sources of energy to survive. As the crew of the Calico investigate the creature, they call upon Godzilla to counter the Magnetic Monster's next target, and he easily drives the creature away. However, it's discovered that the aquatic kaiju is growing increasingly larger as it absorbs more magnetic energy, and the beast uses its power of polarized attraction to swallow the mini-sub containing Capt. Majors and Brock, trapping them within the beast itself. Upon Dr. Darian's suggestion, Godzilla chases the Magnetic Monster to the South Pole, where she believes the beast

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

After an ancient Greek island re-appears in the Earth dimension after 1,000 years, Capt. Majors is hypnotically induced to bring the Calico there by a mysteriously beautiful singing. Upon arriving, the crew discover that the island is the home of the Sirens, three deadly sisters from Greek mythology who entrance male sailors with their hypnotic singing, luring them to the island where they meet their doom. Although the leader of the Sirens, Morphea, initially seems to welcome the crew, they soon learn that they are to be kept on the island after it disappears at sunset by being turned to stone (an idea the Sirens possibly stole from another trio of deadly sisters from Greek mythology, the Gorgons). After the crew open the doors to a chamber against the warnings of Morphea, they release a Chimera, a gigantic fire-breathing mythological monster that is a three-way cross between a lion, a goat, and a serpent. After Morphea exclaims that not even the Sirens can control the Chimera, the

As a result of the pollution caused by a nearby oil spill in Chesapeake Bay, a huge gelatinous monster is spawned (perhaps inspired by Hedorah) that survives by feeding upon various metals. The ameoba-like kaiju, referred to as the Breeder Beast, begins heading towards the U.S. Mint for its stores of gold, silver, and platinum. Godzilla is called by the Calico crew to stop the beast, but the creature's jelly-like substance appears invulnerable to Godzilla's physical attacks. Dr. Darian believes that the Breeder Beast's glowing nucleus may potentially turn it into a living nuclear bomb due to all of the gases and metals the creature has fed upon, so she urges Godzilla and the National Guard not to attack it. However, when Godzilla disobeys and blasts the monster with his laser beams, the beast doesn't explode, and Dr. Darian now believes that the creature has learned to control its rampant energies. Thus, she directs Godzilla to project his laser beams into the Breeder Beast's nucleu

The team becomes stranded in the Himalayas and are imprisoned by a race of Abominable Snowmen. Godzilla must find and rescue them before it is too late.

When the Calico is about to be struck by a falling satellite, Godzilla is called to the rescue. Although the Big G saves the crew by catching the satellite, energy emissions from the device create a freak time warp that sends Godzilla and the Calico back one million years in the past. There they are soon attacked by a Diplodocus, who the much larger Godzilla easily drives away with a few spurts of his fiery breath [actually, the Diplodocus, a prehistoric herbivore which resembled the Apatatosaurus in body form but was lighter and much longer in length with a somewhat elongated head, was a peaceful creature and shouldn't have attacked the crew; for that matter, dinosaurs of that type became extinct before the end of the Jurassic Period, over 100 million years ago, and shouldn't have co-existed with either the Tyrannosaurus or the cavemen seen later in this episode]. While exploring the prehistoric terrain, the crew meet and befriend a tribe of cavemen who they teach to defend themsel
