Godzilla: The Series

As a result of an oil platform in the Gulf of Mexico exploding, a mutant seemingly composed of living fire emerges. As this creature goes on a rampage in the area looking for more combustible substances upon which to feed, H.E.A.T and Godzilla intervene. However, the creature grows larger and more powerful as a result of absorbing and feeding off of Godzilla's powerful incendiary breath.

Another new and dangerous mutant species appears on the scene, this time in the form of gigantic hummingbirds that attack planes flying over San Francisco. Worst of all, this mutant avian species is able to render themselves invisible via the hummingbird trait of flapping their wings faster than any other bird species in the world. As a result of their ability to cloak themselves so as to be invisible to the unaided eye, Godzilla is unable to see the creatures in order to attack them.

While tracking Godzilla to Fort Armstrong, New Mexico the team discover a gigantic mutated scorpion, called Ts-eh-GO by the locals, is on the rampage.

H.E.A.T. tackles a gigantic mutant shrew-like creature, which has somehow merged itself with an artificially generated, experimental tornado, enabling it to transform itself into a living vortex at will (Elsie wittily dubs the whirling beast 'The Shrewster'). In order to maintain its ultra-fast, whirlwind powers, the Shrewster is forced to rapidly consume three times its body weight per day, thus causing it to greedily devour every organic food source in its path, effectively making it an extremely dangerous menace. Because of its ability to transform itself into an organic tornado, Godzilla is unable to get at the beast, and Tatopoulos ends up trapped in the Shrewster's vortex. However, soon after becoming trapped, he activates a device that Craven crafted, which was designed to dissipate the vortex's cyclonic forces, and this succeeds.

H.E.A.T. investigates a gigantic caterpillar-like mutation known as the Megapede, who is rampaging through the neighbor states of Illinois and Indiana. Godzilla is called upon to render assistance, but the Megapede sprays a form of poisonous foam, and also has poison producing spurs along its many legs, both of which serve to keep the Kaiju King at bay. The mega-insect finally climbs atop a building, forms a cocoon, and transforms into a huge winged insectoid creature with the habit of disrupting radar frequencies by rubbing its wings together, thus wreaking much havoc. H.E.A.T. concocts a poison neutralizing foam, which it spreads on the kaiju's wings, allowing Godzilla to attack and defeat the creature more easily.

A new and deadly mutation, a plant-like creature known as Bacillus (who may have been inspired by Biollante), appears and begins wreaking havoc, prompting H.E.A.T. to call upon Godzilla. During the battle, Godzilla is seriously injured and rendered catatonic as the result of being injected with a highly dangerous form of mutated bacteria by Bacillus. In order to save their kaiju ally, Tatopoulos and Monique travel within Godzilla's body in order to carefully exterminate all of the mutant bacterium. Now fully healed, Godzilla attacks Bacillus anew, and eradicates the creature with his incendiary breath.

A traveling carnival arrives at Madison Square Garden, and it's run by a crooked ringmaster known as Theodore P. Bunkum, who specializes in putting various captured mutations on display for public amusement. Bunkum places a hefty bounty on Godzilla, determined to add this most famous mutation to his carnival side show, and this incites H.E.A.T. to attend one of his shows, where they are quickly appalled by his treatment of the various mutations featured in it.

In Miami, Godzilla, H.E.A.T., and Major Hicks battle Skeetera, a mutated bloodsucking mosquito-like insect who adapts the powers of the creatures she feeds on. As they attempt to contain the creature they are interrupted by the mutation rights fringe group known as S.C.A.L.E. (Servants of Creatures Arriving Late to Earth).

While Craven is laid up sick back at H.E.A.T. headquarters, Nick, Randy, Elsie and Monique assist Godzilla in a battle with a Mutant Jellyfish. The Heat-Seeker is engulfed by a mysterious storm which propels the team into a bleak, post-apocalyptic future where Godzilla is dead and the world is dominated by genetically engineered, 5-legged mutations known as Dragmas.
