Season 2

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.

Shady promoter Maximillian Spiel entertains wealthy ticket holders with a series of “cage matches” between giant mutations like the Shrewster and the Giant Centipede. For his next bout, Spiel sets his sights on the “ultimate monster”… Godzilla.

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).

On the Arabian Peninsula, a team of archeologists led by Professor Abrim Kasam unearth an ancient statue of the flying lion Norzzug, the guardian of the ancient city of Amon-Ra. When restoration specialists spray the statue with an anti-oxidant solution, the iron-skinned creature suddenly comes to life.

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.

While on a romantic cruise in Alaska, Nick and Audrey’s ship is attacked by a Giant Turtle.

The HEAT team watches as Godzilla is critically hurt while fighting the Bactillus, an enormous, spongy-green, mucus-covered monster. Nick and Monique must go inside Godzilla to eradicate the bacteria and concoct an antibiotic to weaken the Bacillus.

Elsie is frazzled because her family (unaware of what type of assignment she is working on) is in town for her sister's wedding. When a distress call comes from the local aquarium, the HEAT team finds a gigantic, vulture-like bird of prey.

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.

H.E.A.T. investigates the legendary “Area 51” in Nevada and discovers its true secret is not alien landings, but giant mutated desert creatures created by decades of underground nuclear testing.

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.

While conducting another creature investigation in the valley of Blind Rock, Wyoming, H.E.A.T. meets up with a girl whose brother went missing after he entered an abandoned mine in the area where the sightings took place. Upon entering the mine themselves, the group discovers one of the strangest mutations they have yet encountered, a huge two-headed kaiju known as the Silver Hydra, on account of the fact that it has the ability to spurt a silvery fluid that hardens once it surrounds a living being, thus transforming them into the equivalent of a silver statue, a fate that obviously befell the girl's brother.

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.

Cameron Winter returns to take yet another shot at H.E.A.T. and Godzilla, this time enlisting the aid of the three redneck, would-be-killers of the Big G from the previous episode ""Cat and Mouse,"" and equipping them with powerful machines of destruction (sometimes referred to as 'Battle Mechs'--another thank you to Doc Psy from Centropoholics:). Godzilla, H.E.A.T., and a military unit commanded by Major Hicks battle the machines and destroy them, and the three violent hicks are arrested.

Giant mutated hummingbirds are attacking planes and other aircrafts in San Francisco, but they can flap their wings so fast, they become invisible to human and Godzilla's eyes.

Armillaria, a giant fungus that sucks amino acids out of living matter, shows up in Michigan. Also, the city of Miami sues H.E.A.T. for damages when their latest battle with a giant mutated vampire bat leaves the city in ruins.

A giant mutant that creates fire around itself attacks an oil rig in the Gulf of Mexico.
