    Godzilla Jr.

Voiced By: Frank Welker

Star of the animated series derived from TriStar's Godzilla, Godzilla Jr. hatched from the sole surviving egg laid by the first Zilla — because of the mutant's unstable genetic code, the hatchling possessed the sheer resilience, healing factor and energy breath weapon associated with Godzilla as well as the speed, intelligence and agility of Zilla, while also being sterile.


  • Adaptational Badass: He is a far more durable monster than his father. Whereas his father was killed by 12 missiles hitting each side, he took multiple missiles and still lived. His father lacked an actual Atomic Breath (before being cyberized) while he fires a napalm-like radioactive breath.
  • Adaptational Heroism: Both ways.
    • His father was the antagonist in his debut movie, and while he did destroy most of New York, all he wanted was to lay his eggs until all of his children are destroyed. He on the other hand has no interest in attacking humans, and most of his damages is due to fighting another monster within New York or another major city. He did go on a rampage when he was having a tantrum, but he eventually gets over it. Meta-wise, he is also the third most heroic version of Godzilla, behind the Showa Godzilla after his Heel–Face Turn, and the Hanna Barbera Godzilla.
    • His siblings were the secondary antagonists, attacking humans because they smell like fish, and thus started hunting them out of hunger. While he nearly eats Nick, he instantly realizes Nick was his "father", and thus is very protective of him. His own protectiveness brings to mind the Gentle Giant Godzilla Junior from Godzilla vs. Destoroyah, after maturing into a teenager equalivalent, he is very protective of humans.
  • Adaptational Name Change: His Atomic Breath is called "Power Breath" within the show.
  • Amplified Animal Aptitude: Godzilla frequently displays intelligence and tactical thinking far greater than what one would expect an animal to be capable of.
  • Berserk Button: If you value your life, do NOT mess with his "father" Nick Tatopoulos.
  • Big Damn Heroes: 24/7. Taken to extreme levels during the bad future where he saved the last known humans from the Dragmas. He's considered a hero to the survivors, who erected a statue in his memory in their underground base.
  • The Big Guy: They don't come much bigger.
  • Breath Weapon: A green napalm-like blast of fire. His spines and eyes flash just before he uses it, and it's shown to be hot enough to melt sand into glass.
  • Composite Character: He takes traits from his parent, appearance-wise and ability-wise (such as his ability to dig tunnels), though also has the Atomic Breath of the original Japanese incarnation.
  • Depending on the Artist: His color scheme changes slightly from episode to episode, switching between a muddy brown or a purplish grey.
  • Destructive Savior: Even though he kills monsters who actively cause damage, he inevitably causes damage whenever he fights another monster in a major city or location.
  • Determinator: Typical for any version of Godzilla. But it gets to Offscreen Moment of Awesome levels in the Bad Future, where he apparently saved the entirety of what's left of the humans in New York, if not the remainder of humanity on the planet by fighting off an entire pack (if not the entire race) of Dragmas in what turned out to be his Last Stand.
  • The Dreaded: Godzilla is over 150 feet tall, looks like a cross between an iguana and a Tyrannosaurus rex, and breathes a stream of atomic fire. The citizens of New York are quite justifiably terrified of him. Well, those reasons and the whole fact that his biological father kinda destroyed a good chunk of the infrastructure of New York during the movie...
  • Extremely Protective Child: He is very protective of his adoptive father Nick Tatopoulos.
  • Finishing Move: Usually his atomic breath.
  • Fireballs: In the two Gameboy games, Godzilla's green atomic breath is replaced by balls of green fire it shoots from its mouth.
  • Fragile Speedster: By kaiju standards, anyway. While still able to take a beating from other giant monsters, conventional weapons have consistently been shown to be a threat to him.
  • Genius Bruiser: He's been shown to be surprisingly clever at times, outwitting some monsters, responding appropriately to Nick's instructions, and even recognizing when the situation calls for different tactics.
  • Gentle Giant: Has his moments. When he's not fighting monsters, he's usually shown just hanging out in the Hudson, minding his own business. Justified, as Nick spends a considerable amount of time actively teaching him to be gentle around humans.
  • Gigantic Adults, Tiny Babies: As a new hatchling, Junior was just a bit bigger than adopted father Nick when they first met. He eventually grows to match the skyscraper size of his biological father.
  • Good Is Not Soft: He doesn't care if it's humans or monsters, he doesn't hesitate to kill if he or Nick is threatened.
  • Happily Adopted: He imprinted on Nick as his father and has loyally followed him since.
  • Harmless Freezing: The one shot comic "Ice Cold Winter" has Godzilla being frozen solid by Cameron Winter, only to emerge none the worse for wear when H.E.A.T. frees him.
  • Healing Factor: Best demonstrated in "Where is Thy Sting?" where a wound inflicted by Ts-Eh-Go heals in seconds after the scorpion's poison is removed from Godzilla's system.
  • Hero with Bad Publicity: Understandably, seeing as his father destroyed a good chunk of New York, he often causes damage even when he stops whatever Monster of the Week appears, and he's been mind controlled into rampages, which beyond giving him a bad reputation also leads to a number of attempts to kill him.
  • Heroic Sacrifice: In the Bad Future, he died holding off the D.R.A.G.M.A., saving the lives of thousands in New York.
  • Imprinting: Due to Nick being the first thing he sees after hatching (as well as Nick being covered in amniotic fluid from the other Godzilla eggs), Godzilla assumes that he is his parent.
  • In-Series Nickname: "The G-Man" as Randy frequently calls him.
  • It Can Think: He isn't just big and strong, he is also intelligent, having won a number of fights through his intellect when brute force wasn't enough.
  • "King Kong" Climb: He climbs to the top of the Empire State Building during the show's opening song, as seen in the above image.
  • Lantern Jaw of Justice: Like his parent, Godzilla has a large underbite and very prominent chin.
  • Last of His Kind: Can't reproduce asexually and killed his resurrected biological-turned-cyborg parent, the original Godzilla, in "Monster Wars".
  • Legacy Character: To Godzilla Sr. Needless to say, Junior far surpassed his father's legacy.
  • Lightning Bruiser: He is a giant, but he's also extremely fast.
  • Love Hurts: In one episode, he fell in love with a mutant Komodo dragon, Komodithrax, and became her mate and surrogate father of her egg (she could reproduce asexually). When she and the egg were lost at the end of the episode, Junior roared his grief and despair to the world.
  • Meaningful Name: It took a while, but Jr. earned his name as "God Incarnate".
  • Nature vs. Nurture: The main difference between this Godzilla and his father: his father was more or less a giant animal while Nick spends most of the first episode teaching him to be gentle towards humans. This results in him being humanity's protector rather than its destroyer.
  • Power Glows: His eyes and spines flash green right before he uses his atomic power breath.
  • Redeeming Replacement: Whereas his father was a destructive monster (not out of maliciousness, just by virtue of being a giant mutant iguana trying to nest in a major city), Junior is friendly towards Nick (and by extension, humanity in general) and protects the world from other mutations. He can also be seen as this in a Meta sense, given that he is much Truer to the Text than his father and was much more well-received by the fans.
  • Roar Before Beating: Always lets out a roar before tackling the Monster of the Week.
  • Sea Monster: He's capable of remaining submerged indefinitely and can cross entire oceans whenever he pleases.
  • Strong as They Need to Be: Physically how strong he is, how durable he is, and the punch his Breath Weapon packs depends on the needs of the plot. Normally he can tunnel through bedrock, but in one episode his head is caught in a bridge.
  • Superior Successor: Has all the strengths of his parent, and also has classic-style atomic breath. This is showcased in his and Cyber-Godzilla's fight, as despite having been resurrected much stronger than before, Jr. still wins and is obviously stronger.
  • Tail Slap: One of his most effective attacks.
  • Tunnel King: Like his parents he's an adept burrower. He can tunnel through bedrock easily.
  • Truer to the Text: Unlike his father, this Godzilla has more in common with his Toho inspiration. He fires atomic breath, he's difficult to be taken down by conventional military weapons and does frequent battles with other giant monsters.
  • Vegetarian Carnivore: Inverted. He's a mutated green iguana, which are herbivores, but his diet consists mainly of fish. He tried to eat Nick and Audrey in the first episode, and also chased after giant mutant rats. Amusingly, the team once tried to feed him seaweed substitute to prevent him overeating the local fish stocks, but he simply spat it back out once he tasted it.
  • Weakened by the Light: In both "The Winter of Our Discontent" and "Cash of the Titans", Godzilla is blinded by bright lights, leaving him vulnerable to attack by the Cyber-Flies and Rhinosaurus respectively.
  • The Worf Effect: In an alternate future in which the world was overrun by genetically engineered monsters known as Dragmas, Godzilla was slain in battle against the creatures. Though if Craven is to be believed, he died fighting off an entire pack of Dragmas, if not the entire race at that point, to save the last of humanity in New York City.
  • You Shall Not Pass!: According to the future Craven, Godzilla died holding off an entire pack of D.R.A.G.M.A., saving what was left of New York in the process.

    Dr. Niko "Nick" Tatopoulos 
https://static.tvtropes.org/pmwiki/pub/images/gts_nick_outdoors_5152.png
Proud "dad" of a giant mutated lizard.
Voiced By: Ian Ziering

  • Adaptational Dye Job: In the film, Nick has dark brown hair and eyes. Here, he has blue eyes and his hair is a lighter shade of brown.
  • Adaptational Jerkass: Downplayed, but in the movie, Nick had some empathy for the first Godzilla and seemed somewhat saddened by his death. In the series, he shows no compassion for the first Godzilla when he dies or when he's resurrected as Cyber-Godzilla.
  • Arbitrary Skepticism: Doesn't believe in the Loch Ness Monster, despite all the things he's seen and done up until that point in the series, including meeting aliens just a few episodes earlier.
  • Badass Bookworm: While a scientist first and foremost, Nick is quite capable of picking up a gun to take on mutations when the situation requires it.
  • Embarrassing Nickname: Cameron Winter refers to him by his college nickname "Nickels", a not-so-subtle jab by Winter at Nick's financial prospects.
  • Fatherly Scientist: After Junior imprints on him, Nick assumes the role of his father. Without his influence, Godzilla would just be another mutation for H.E.A.T. to deal with.
  • The Leader: Leads the team and is in charge of Godzilla.
  • Meaningful Name: Niko is a short form of Nikolaos, which is Greek for "victory of the people". Guess what his discoveries lead to in the film and throughout the series.
  • Nerves of Steel: A bit in the film. When Godzilla Sr. shows up to check him out during the first fish bait trap, the big guy was inches from Nick. Nick also noticed some soldiers getting ready to shoot Senior and signals them to hold their fire despite not holding any military rank.
  • Nice Guy: Usually amiable and tries to get along with everyone.
  • No Pronunciation Guide: Averted. In the movie his last name was The Unpronounceable. Here, all the characters can pronounce his surname with no difficulty.
  • Papa Wolf: Let's just say it's not a good idea to do anything that will harm Godzilla around him.
  • Took a Level in Badass: He's a lot more pro-active in the series than he was in the movie, Fridge Brilliance kicking in when one is considered "dad" by a 150-ft second-generation mutated lizard.
  • Tuckerization: Named after creature/visual designer Patrick Tatopoulos, who worked on the 1998 film.
  • Verbal Tic: He has a tendency to repeat one-word orders three times during emergencies.
    Nick: Go, go, go!
  • The Worm Guy: The Trope Namer, and occasionally still called by it despite having changed the purview of his "research" to studying a giant lizard.

    Dr. Elsie Chapman 
Voiced By: Charity James

  • Ascended Extra: She was a minor character in the film who largely disappeared after Godzilla appeared in New York. Here, she is given a much larger role.
  • Betty and Veronica: Serves as the Betty to Audrey's Veronica. Elsie is a down-to-earth scientist who occasionally flirts with Nick (especially to annoy Audrey), while Audrey is an ambitious anchorwoman who is actively in an relationship with Nick.
  • The Chick: Generally the most level-headed member of the team.
  • Deadpan Snarker: Many of her lines are this.
  • Fiery Redhead: Elsie has a sharp wit and is not afraid to jump headfirst into danger or flirt with Nick in front of Audrey.
  • The Glorious War of Sisterly Rivalry: The Smart sister to her to-be-married Beautiful sister Kate in "Wedding Bells Blew", much to Elsie's annoyance.
  • Redhead In Green: Has red hair and usually wears a green sweatshirt.
  • Tomboy and Girly Girl: The Girly Girl to Monique's Tomboy.

    Dr. Mendel Craven 
https://static.tvtropes.org/pmwiki/pub/images/gts_mendel_outdoors_4847.png
Voiced By: Malcolm Dunare

  • Adaptation Dye-Job: Mendel's originally a short-haired brunette in the film. Here, he's a blonde with a ponytail.
  • Ascended Extra: He was a minor character in the film who largely disappeared from the story after Godzilla appeared in New York. Here, he is given a much larger role.
  • Butt-Monkey: Usually gets the short end of the stick.
  • Cowardly Lion: Make no mistake; this guy might be even afraid of his own shadow but the fact he still stays with and helps the company that deals with giant monsters in order to save people is a testament on how much of a good person he is.
  • Ink-Suit Actor: His Adaptation Dye-Job actually inverted this, as while Malcolm Dunare did come back to voice the character, Dunare has brown hair and it was cut short in the movie, as opposed to the long blond hair Mendel sports here.
  • Meaningful Name: Craven means "coward".
  • Sickly Neurotic Geek: In short: a summer cold from the movie, rat dander, pollen, bee stings, chances of bronchitis, getting over a normal cold, plenty of sun protection on using SPF 90 sunscreen and a robe, sand making him itch, sun giving him blisters, earaches from swimming, requires the occasional use of an inhaler, plus allergies to several "variety of trees and shrubs, most grasses, a couple dozen animals, 25 or so foods, rubber, and rubber products". The ONE time he truly gets sick is after getting infected by the Giant Bacillus's slime in "What a Long, Strange Trip It's Been". As lampshaded in the episode "Hive":
    Monique: *exasperated* "Is there nothing he is not allergic to?"
    Elsie: *cheerfully* "Nope."
  • The Smart Guy: He's the team's tech wizard.
  • Smart People Build Robots: As the team's Smart Guy, Craven builds and maintains N.I.G.E.L., who in Craven's own words is "the most sophisticated robot on the planet".
  • Took a Level in Badass: While he has his fair share of moments, his future counterpart tops them all. After the Dragmas took over, he became the leader of a resistance and became very buff in order to survive.

    Randy Hernandez 
Voiced By: Rino Romano

  • Amazon Chaser: His attraction to Monique is evident the first time they meet. The first time they meet involves her judo-flipping him.
  • Gratuitous Spanish: Although prominent in the episode "D.O.A." where they're in Central America, it must be noted that Portuguese is different from most forms of Spanish. Both are Romance languages, meaning they're descended from Latin. Some misunderstandings are understandable.
  • Hidden Depths: He learned Navajo, one of the hardest languages to learn, because he thought it was cool that the Imperial Japanese forces never cracked it during the Pacific theater in World War II.
  • The Lancer: To Nick, being younger, less mature, and not as well-versed in science as he does.
  • The Nicknamer: Refers to his team mates by nicknames such as “Jefe” for Nick, “Doc” for Craven and “G-Man” for Godzilla Jr.
  • Playful Hacker: Messes with NIGEL on an episodic basis.
  • Slap-Slap-Kiss: With Monique.
  • Twofer Token Minority: Black-Portuguese.

    Monique Dupre 
https://static.tvtropes.org/pmwiki/pub/images/monique2_4823.jpg
Voiced By: Brigitte Bako

  • Action Girl: Very competent in combat and infiltration.
  • Bare Your Midriff: Her usual outfit. Her on-the-field outfit has a proper T-shirt.
  • The Big Guy: Though Godzilla Jr. is this for the team by stepping in to fight the Monster of the Week when the team almost inevitably cannot defeat it with mundane weapons, Monique serves this role for the team when the action is on a human scale. She is by far the best shot and fighter on the team.
  • Boobs of Steel: Has a fairly large bust and is by far the most skilled fighter on the H.E.A.T. team.
  • Boyish Short Hair: She sports it.
  • Character Development: Probably has the most of the main cast, as she develops from an openly hostile antagonist who thinks every monster needs to be destroyed, to a trusted and loyal team member who actively fights her own superiors over needing Godzilla as an ally and supporting the creation of a "sanctuary" on the Isla del Diabolo.
  • Cheese-Eating Surrender Monkeys: Averted. She's the most couragous member and best fighter on this team of badasses.
  • Deadpan Snarker: Even more than Elsie.
  • Defrosting Ice Queen: When she first encounters Randy, his crush on her was unrequited, and working with the team was strictly business-only. Later on, she became a bit more comfortable with the team and started liking Randy a little.
  • Depending on the Artist: She went from broad-shouldered and muscular in season one, to athleticly skinny in season 2.
  • Determinator: Still kept going in spite of a broken leg in "Hive" until the end as one example. Which leads to...
  • Don't You Dare Pity Me!: Practically jumped down Craven's throat when he offered to help her with her broken leg. It took a volcanic eruption and Craven flipping out at her to convince her to (grudgingly) admit that it was okay to accept help.
  • Gratuitous French: Speaks French on occasion.
  • The Lancer: Especially earlier on when she was very much in favor of destroying every mutation the team encountered, Godzilla included.
  • Ms. Fanservice: Is quite attractive, and often flaunts it, unknowingly. "The Twister" has her wear a very revealing bikini.
  • Peek-a-Bangs: Not entirely covering her left eye, but enough that it covers Sexy (Randy's perspective), Deceptive (a French secret agent), and Antisocial (usually butting heads with the others' non-lethal preferences).
  • The Sixth Ranger: She was initially sent to destroy Godzilla before becoming the newest member of the team.
  • Slap-Slap-Kiss: With Randy.
  • Tall, Dark, and Snarky: Is as tall as the boys of her team, wears dark clothes and makeup, and speaks almost exclusively in sarcasm.
  • Tomboy and Girly Girl: The Tomboy to Elise's girly girl.
  • The Quiet One: She doesn't talk very much, despite getting in the majority of sardonic quips in the series.
  • Twofer Token Minority: She is a French-Vietnamese woman.

    N.I.G.E.L. 
Voiced By: Tom Kenny

  • The Chew Toy: He gets destroyed on an episodic basis, is constantly being reprogrammed by Randy and has a built-in AAAAARRRRGGHH! whenever he dies.
  • Fun with Acronyms: Next-Millennium Intelligence Gathering Electronic Liaison.
  • Funny Robot: Between his ridiculous impersonations and his many, many deaths, N.I.G.E.L. is the most consistent source of humor on the show.
  • Future Badass: In "Future Shock", N.I.G.E.L. is equipped with a much larger and more robust body, presumably to help withstand life in a post-apocalyptic hellhole where replacement parts would be scarce.
  • Iron Butt Monkey: N.I.G.E.L. gets destroyed on a regular basis. But no matter how damaged he gets, Mendel always manages to rebuild him, even when there's nothing left to rebuild him from..
  • Land, Sea, Sky: While usually just terrestrial, several episodes give N.I.G.E.L. an aquatic mode for underwater operations. The Godzilla: The Series Gameboy game also adds a helicopter mode to allow him to observe mutations up close, with predictable results.
  • Shock and Awe: While he most of the time he acts The Chew Toy, he does carry cables that can deliver a powerful electric shock.
  • Speaks in Shout-Outs: Due to Randy constantly reprogramming him to troll Craven, N.I.G.E.L. frequently impersonates well-known actors and characters, such as John Wayne and James Bond.
  • Surveillance Drone: In "Monster Wars", N.I.G.E.L. is shown to contain numerous spider-like robots that Craven is able to use to investigate the Sandy Point Military Base remotely.
  • Tank-Tread Mecha: N.I.G.E.L.'s basic and future forms both use tank treads to move around.
  • Team Pet: Of the Robot Buddy variety. While N.I.G.E.L. does have his uses, his role in the series is largely comic relief (even when he's being useful he ends up destroyed).
  • They Killed Kenny Again: Gets wrecked Once an Episode, more than a few of them have been from Godzilla (He's even voiced by Tom Kenny).

Kaiju

    In General 
  • Brain Washed: During the "Monster Wars" series, most of the monsters that had survived up to this point are put under mind control by the Leviathan aliens.
  • Demoted to Extra: While a handful of the monsters do return later in the series (most notably in the "Monster Wars" trilogy and "S.C.A.L.E."), they are mostly limited to extended cameos.
  • Kaiju: Given that this series is part of the Godzilla franchise, this should be a given.
  • Monster of the Week: Most monsters are limited to one appearance, although a handful survive to have cameos later in the series.
  • Non-Malicious Monster: This series constantly points out that most of the monsters are just acting out their natural life cycles like any other animals. However, there are several notable exceptions, including the D.R.A.G.M.A. (creatures bred specifically to kill humans by the millions), the Techno-Sentient (an alien lifeform hellbent on causing global Armageddon), the Crackler (a living dream attacking anything his creator subconsciously hated), and basically anything that Cameron Winter had a hand in creating.
  • Tragic Monster: Most of the monsters are just mutated animals trying to live their lives. Unfortunately, their size means that they can no longer do so without causing rather severe destruction. This necessitates H.E.A.T. and Godzilla hunting them down, ending in the monsters' destruction (or at the very least, spending their lives imprisoned in remote locations where they can do no harm).

    Mutant Giant Squids 
https://static.tvtropes.org/pmwiki/pub/images/mutant_giant_squid.png

Debut: "New Family: Part 2"

The mutant giant squids are the first antagonistic monsters in the series (though too weak to be much of a real threat), attacking swimmers and boats off the coast of Jamaica, which was then blamed on Godzilla and resulted in the military attacking him. Later, H.E.A.T. discovers they are responsible for the attacks and they are killed by Godzilla, only for it to be revealed they are just a food source for a much bigger mutation.


  • Always a Bigger Fish: They may be strong enough to threaten humans and small ships, but they are little more than Cannon Fodder for bigger mutations like Godzilla and Crustaceous Rex, the latter of which is actually responsible for driving them to the surface in the first place.
  • Combat Tentacles: Comes with being giant squid and all. They specialize in grabbing people from boats (when they aren't bothering to pull whole boats underwater).
  • Giant Squid: Obviously.
  • The Goomba: They appear in both Gameboy games as minor recurring enemies.
  • Small Role, Big Impact: Crustaceous Rex may be the main antagonist of their episode, but the squids are what drive the plot. They were responsible for attacking swimmers and boaters in Jamaica, which caused Monique to tip off the military to Junior's existence, nearly leading to his death when Hicks and his men attacked him. Later, Godzilla returns to fight them off when they attack Nick, which in turn leads to C-Rex attacking Jamaica (due to Godzilla destroying his main food source), revealing to the world that there are more mutations out there.

    Crustaceous Rex (a.k.a. C-Rex) 
https://static.tvtropes.org/pmwiki/pub/images/c_rex_4.png

Debut: "New Family: Part 2"

Godzilla's first opponent in the series, Crustaceous Rex is a mutant crustacean that first appeared off the coast of Jamaica, feeding off mutated giant squids until Godzilla destroyed its food supply. After being defeated by Godzilla, C-Rex would disappear until the Leviathan aliens summoned him to Site Omega to take part in their plans to use Earth's monsters to soften up the Earth's defenses. Crustaceous Rex was one of the few monsters to survive the "Monster Wars" three-parter, at which point it was captured and became part of the Mutant Research Facility on Monster Island for the remainder of the series.


  • Advertised Extra: C-Rex battles Godzilla on the cover of the "Godzilla: The Series- Monster Wars" video game, despite the fact that he doesn't appear anywhere in the game itself.
  • Bad Future: In an alternate future in which the world was overrun by genetically engineered monsters known as Dragmas, C-Rex was released from Monster Island to fight them, but was slain in battle against the creatures.
  • Bizarre Taste in Food: It feeds on tar, and is seen ripping up and eating asphalt after its normal food source (mutant squids which produce tar as a defence) is killed off by Godzilla.
  • Combat Tentacles: He uses his tentacles to grapple with his opponents.
  • Food Chain of Evil: Was the primary predator of the giant squids that were attacking people.
  • Giant Enemy Crab: It's an enemy kaiju that is at least partially based on crustaceans.
  • Mix-and-Match Critters: It has the head and tentacles of a cuttlefish with a crustacean-like shell and two legs, giving it a Tyrannosaur-like posture.
  • Off-Model: When he arrives at Site Omega at the end of "Monster Wars: Part 1", he is erroneously colored brown instead of his usual yellow.
  • Recurring Character: Comes back for the "Monster Wars" trilogy, then later "SCALE."
  • Starter Villain: The first monster Godzilla Junior fights and the one that reveals there's more mutations out there.
  • Super Spit: It's able to shoot tar from its mouth.
  • Trap Master: In the game, it's Tar Shot is capable of temporarily immobilizing Godzilla.
  • Unexplained Recovery: Survives his encounter with Godzilla after the latter severed his tentacles and buried him alive with a rock slide. Given that many cephalopods can regrow missing tentacles, this is likely due to C-Rex having a Healing Factor rather than a result of a continuity error.
  • Warm-Up Boss: The first antagonistic monster to appear in the series, and while its greater size made it more of a threat than the giant squids it preyed on, against Godzilla it still lost without putting up much of a fight.

    El Gusano Gigante 
https://static.tvtropes.org/pmwiki/pub/images/el_gusano_gigante.png

Debut: "D.O.A."

A giant worm mutated by a rare poisonous plant in Mexico, El Gusano Gigante proceeded to ravage the local farmland until confronted by H.E.A.T. and Godzilla. H.E.A.T. discovers El Gusano's weakness to extreme heat, and Godzilla is able to shrink the worm back down to its original size with a sustained blast of his atomic breath. El Gusano Gigante would later regrow to kaiju-sized and was taken over by the Leviathan aliens, who deployed it to attack Moscow. After H.E.A.T. destroyed the Leviathan aliens' control beacon, it turned on its former masters but was quickly killed off.


  • Adaptational Backstory Change: In the "Monster Wars" game, El Gusano Gigante first surfaces in Nigeria, in contrast to the series where he first appeared in Mexico and was deployed to Moscow during the Monster Wars (Nigeria was where the Giant Bat first originated).
  • Big Creepy-Crawlies: It's a giant worm.
  • Evil Is Bigger: At full size, El Gusano is the largest kaiju Godzilla faces in the entire series. The video game ''Godzilla: The Series- Monster Wars" lists his length as 400 meters.
  • Extra Eyes: It has six eyes.
  • Gratuitous Spanish: The only monster in the entire Godzilla franchise with a Spanish name.
  • Growing Muscles Sequence / Miracle-Gro Monster: When the South American military attack El Gusano and Godzilla with a chemical weapon of theirs, it only hurts Godzilla. It ends up mutating El Gusano even further, not only making him all around larger, but also giving him spikes down his back and even teeth.
  • Killed Off for Real: When the aliens' mind control over him is broken, he fights back against his would-be controllers. It doesn't go so well.
  • Kryptonite Factor: Intense heat, like from Godzilla's Breath Weapon.
  • Meaningful Name: Its name is Spanish for "the Giant Worm".
  • Playing with Fire: In his video game appearance, El Gusano is able to shoot fire from his mouth (ironically, he is weakened by fire in the series.)
  • Recurring Character: Comes back for the "Monster Wars" trilogy.
  • Shockwave Stomp: His secondary attack in the "Monster Wars" game, where he slams his head to the ground to send out shockwaves
  • Spikes of Villainy: He has mult-pronged horns on his head, two rows of dorsal plates down his back, and eight bony spikes protruding from his tail.
  • Tunnel King: He is a mutant earthworm, after all.
  • Unexplained Recovery: Godzilla's atomic breath reduces it back to an ordinary worm, yet it has completely returned to its massive proportions by the time of the "Monster Wars" trilogy.

     Nanotech Creature 
https://static.tvtropes.org/pmwiki/pub/images/nanotech_creature.png

Debut: "Talkin' Trash"

A colony of microbes with nanotech drivers attached to them, the Nanotech Creature was created by Dr. Felix Hoenikker of the Manhattan Institute for Advanced Technology to combat New York's growing refuse problem. However, it was activated before it had been properly tested and, unable to distinguish between garbage and non-garbage, began consuming everything in its path. H.E.A.T. is able to create a computer virus that separates the microbes from their nanotech drivers, petrifying the creature and allowing Godzilla to shatter it.


  • Adaptational Late Appearance: It appears in the video game adaptation of "Monster Wars", despite its sole appearance in the series taking place well before the first appearance of the Leviathan aliens.
  • A.I. Is a Crapshoot: The minute it was activated, the creature attack a nearby scientist and possibly would have devoured her.
  • Blob Monster:It's just a vast colony of nanorobotic microbes so it'll take any shape it wants. Its preferred form is the shape of the microbes.
  • Expy:The Nanotech Creature is probably based on Hedorah given that both monsters thrived on waste.
    • Like Destroyah, the Nanotech Creature is composed of an entire colony of microorganisms joined together in one massive body.
  • Gone Horribly Wrong:The creature could have benefitted humanity if its creators had been able run more tests to fix all the flaws in its design. However, thanks to Dean Whitehead pushing them to have it launch before it was ready under the threat of unemployment, it didn’t happen. When it was activated, all hell broke loose.
  • Grey Goo: It was created to consume petroleum-based waste and convert it into more nanomachines.
    Dr. Hoenikker: In a nutshell, Nick: a Nanotech feeding frenzy. The more petroleum it consumes the more it replicates, and the more it replicates the more it needs to consume.
  • Miracle-Gro Monster: When first released, it is small enough to fill a trash can-sized cylinder. As it consumes more petroleum-based waste, it grows until it rivals Godzilla in size.
  • Muck Monster: Its entire body is composed from all the petroleum-based products it consumed.
  • Nanomachines: Its body consists of billions of microbes with nanotech drivers attached to them to (theoretically) allow the whole thing to be controlled remotely. It doesn't go so well.
  • Shout-Out: The Nanotech Creature's creator Dr. Felix Hoenikker is possibly a reference to the novel Cat's Cradle by Kurt Vonnegut. In the novel, a character named Felix Hoenikker invents a substance known as ice-nine, which converts all water it comes into contact with to more ice-nine; the Nanotech Creature consumes petrochemicals to create more of itself.
  • Taken for Granite: It petrifies once the computer virus was injected into it. Godzilla took the chance to smash it to bits.
  • The Worm That Walks: It's really a colony of millions of microbes controlled by nanotech drivers, acting as one giant entity.

     Cyber Fly 
https://static.tvtropes.org/pmwiki/pub/images/cyber_fly.png

Debut: "The Winter of Our Discontent"

A squadron of mass-produced robotic flies created by Cameron Winter, the Cyber Flies were instrumental in Winter's plot to take control of Godzilla.


  • Animal Mecha: They're human-sized mechanical flies.
  • Beware My Stinger Tail: They have scorpion-like tails equipped with a wide variety of weapons. One of them uses it to inject Godzilla with a tranquilizer, while another attaches a neurotransmitter that allows Cameron Winter to control Godzilla.
  • Mecha-Mooks: Compared with most of Godzilla's opponents, the Cyber Flies are definitely lacking in the personality department, since the focus of their episode is Cameron Winter taking control of Godzilla, with the Cyber Flies just being a means to that end.
  • Shock and Awe: The Cyber Flies show the ability to fire bolts of electricity as a ranged attack.

     Mutant Rat 
https://static.tvtropes.org/pmwiki/pub/images/giant_rat.png

Debut: "Cat and Mouse"

A large number of giant rats that appear in large burrows beneath the New York Subway System. They are confronted by a group of amateur monster hunters as well as H.E.A.T. and Godzilla, for whom the rats are his natural prey. The rats' underground nest is eventually sealed off from the Subway and flooded by Godzilla, though the Big Rat later reappears as part of the Leviathan Aliens' monster army.


  • Attack! Attack... Retreat! Retreat!: They pursue Godzilla down one of his tunnels, until they see that he's tunnelled directly into the Hudson River, flooding the rats' nest.
  • Bald of Evil: Both the medium-sized rats and the big one are hairless.
  • Extra Eyes: The big rat has six eyes that glow in the dark.
  • The Goomba: The Gameboy Color adaptation of "Monster Wars" features the mutant rats as a recurring enemy for Godzilla to fight in between the bosses.
  • King Mook: The big rat, being roughly the size of a large van and having a much stockier build than its smaller counterparts.
  • Kill It with Water: After sealing off the rat's nest from the rest of the subway, Godzilla burrows into the Hudson River, flooding the rats' lair and presumably drowning most of them.
  • Lean and Mean: The smallest rats are much slimmer than the larger rats, but just as vicious.
  • Rodents of Unusual Size: The Rats comes in different sizes: small, medium and a big one. Note that even the "small" ones are the size of horses.
  • Scary Teeth: Their mouths are filled with jagged, misshapened teeth. At least one of the rats shows the ability to chew through the side of a van.
  • What Happened to the Mouse?: Despite being part of the Leviathan Aliens’ monster army, the big rat has never been seen again after being sent out. Either it has somehow escaped them or had been killed off-screen.
  • You Dirty Rat!: They're mutated rats the size of horses that have started attacking people.

     Crackler 
https://static.tvtropes.org/pmwiki/pub/images/crackler.png

Debut: "What Dreams May Come"

The Crackler is an electromagnetic projection kaiju created from the dreams of a repressed man named Sydney Walker while he was undergoing Theta-wave therapy for his insomnia. As a result, the Crackler acted on the man's pent-up aggression, targeting his neighbors' apartment and his place of work. Even after Walker is woken up, the Crackler continued his rampage until Randy provoked Sydney into losings his temper, releasing all of his repressed rage and leaving the Crackler too weak to fight back against Godzilla.


  • Expy: A dream monster that controls electricity? Same concept as Gabara of All Monsters Attack, but much better executed.
  • Extra Eyes: It has six eyes on stalks along the sides of its heads.
  • Giggling Villain: Makes a noise that sounds a lot like laughter. Could easily have been named the Cackler.
  • Hoist by His Own Petard: The Crackler gets killed by the projectile it threw at Godzilla.
  • Lean and Mean: The Crackler has a rather lanky physique and is one of the only deliberately malicious monsters in the series.
  • The Power of Hate: It's strength and weakness. Once its master releases all his suppressed rage, it was easy pickings for Godzilla.
  • Punny Name: Has electrical powers and cackles a lot.
  • Shock and Awe: The Crackler has a variety of electric attacks, probably based on its master's occupation as an MTA worker charging the city's electric buses.
  • Tulpa: The personified frustration of an emotionally repressed man. It acts on the anger he's too meek to express and targets the people and things that inspired it.
  • Who's Laughing Now?: Probably why it sounds like it's laughing, as it's acting on Sydney Walker's repressed emotions.

    Cryptocledius 
https://static.tvtropes.org/pmwiki/pub/images/cryptocleidus.png

Debut: "Leviathan"

While H.E.A.T. was descending in a minisub to investigate the Leviathan spaceship, a pair of prehistoric sea creatures identified as Cryptocledius attacked their vessel until Godzilla managed to fend them off. Later, as H.E.A.T. was making their escape from the sunken spaceship, the Cryptocledius again attacked their escape pod, but Godzilla again intervened, subduing both with a rock slide. One of the sea monsters would reappear in the "Monster Wars" three-parter, and was deployed to attack Hong Kong by the Leviathan aliens. After breaking free of their control, it rebels against its former masters, only to be killed off.


  • Ambiguous Situation: While its generallly regarded as having been killed off at the end of "Monster Wars" since it never reappeared, it wasn't shown being directly hit by the Leviathan aliens' weapons and could have just as easily disappeared into the sea.
  • Informed Species: There's a real plesiosaur genus known as Cryptoclidus, but this monster only very remotely resembles the actual animal.
  • Killed Off for Real: When the aliens' mind control over him is broken, he fights back against his former masters. It doesn't go so well.
  • Make Me Wanna Shout: In the video game Godzilla: The Series- Monster Wars, it gains an underwater sonic attack.
  • Multi-Armed and Dangerous: The Cryptocledius has six limbs: two sets of flippers for underwater propulsion, and a set of clawed forelimbs that it uses to crawl onto land.
  • Prehistoric Monster: It's a prehistoric marine reptile that has inexpicably survived to the modern day, rather than being another mutation.
  • Recurring Character: Comes back for the "Monster Wars" trilogy.
  • Sea Monster: Its much bigger than any known marine reptile. Concept art shows it to be large enough to lift the H.E.A.T. Seeker out of the water.
  • Skull for a Head: Although it doesn't seem to be actual bone, the mutation seems to have given them skull-like faces.
  • Spikes of Villainy: It has rows of spikes down its back and horn-like projections along the back of its jaw.
  • Stock Ness Monster: Cryptocledius is a mutant plesiosaur.
  • What Happened to the Mouse?: When the Cryptocledius first appeared there were two of them but there was only one shown in the Monster Wars three-parter.

    Reptilians 
https://static.tvtropes.org/pmwiki/pub/images/reptilian.png

Debut: "Leviathan"

The Reptilians are a group of quadrupedal bear-sized monsters created by the Leviathan aliens to serve as guard dogs aboard their ship.


  • Attack Animal: Dr. Preloran even refers to them as "guard dogs".
  • Body Horror: Their jaws open sideways, revealing a pair of tongues covered in tendrils, as well as multiple tentacles they use to ensnare their prey.
  • Combat Tentacles: The Reptilians are able to project numerous tentacles from their mouths that can extend considerable distance. Their primary means of attack seems to be binding intruders from a distance.
  • Cyclops: They have what appears to be a single red eye in the center of their foreheads.
  • Everything's Better with Dinosaurs: Well, not where these things are concerned.
  • Mix-and-Match Critters: They are genetically engineered from ancient dinosaur DNA to serve as guard dogs for the Leviathan aliens.
  • Raptor Attack: They have raptor-like claws on their forelimbs and operate in packs. Not surprising, given they are genetically engineered from dinosaurs specifically to serve as alien guard dogs, so incorporating raptor DNA would make sense.
  • Spikes of Villainy: They have rows of spikes running down their backs, as well as stegosaur-like spikes on their tails.

    Queen Bee 
https://static.tvtropes.org/pmwiki/pub/images/mutant_bee_queen.png

Debut: "Hive"

When H.E.A.T. was sent to investigate reports of giant carnivorous plants on the volcanic island of Santa Marta, Craven and Monique discovered a giant beehive in the hotel, with Nick and Elsie reasoning that the plants were mutated by irradiated ash, whose pollen mutated the bees who then further spread the mutation to other plants. Both the plants and the bees are killed off when the volcano erupts again, though the Queen survived and reappeared as one of the pawns of the Leviathan aliens. After being deployed to Moscow, the Queen Bee would turn on her masters after their control beacon was destroyed, though she was shot down.


  • Bee Afraid: She is a gigantic bee.
  • Big Creepy-Crawlies: Again, she's a giant bee.
  • Buried Alive: Queen Bee seemingly meets her end when Godzilla buries her deep within an underground chasm at the end of "Hive," but we later find out she survived.
  • The Cameo: In the later episode "Trust No One", one of the forms the DNA Mimic takes is a giant bee identical to one of the mutant drones.
  • Flunky Boss: In the video game, the Queen is able to summon more drones to attack Godzilla.
  • Food Chain of Evil: The Bees have a dark example of symbiosis with the radioactive planets. The plants provide the bees with sustenance and the bees spread the plants' seeds throughout the island and eventually the world.
  • Giant Flyer: She and all of her drones are kaiju-sized bees.
  • Hive Mind: A bee hive mind, naturally.
  • Killed Off for Real: When the aliens' mind control over her is broken, she fights back against her would be controllers. It doesn't go so well.
  • Large and in Charge: The bus-sized Queen dwarves her car-sized drones.
  • Make Some Noise: In the Gameboy Color game, the Queen Bee has the ability to create damaging sound waves from her wings.
  • Recurring Character: Comes back for the "Monster Wars" trilogy.
  • Shout-Out: The way the bees' ecosystem is created from a volcano is similar to The Black Scorpion.
  • Spike Shooter: The drones are able to shoot their stingers at enemies. The Queen takes it a step further by being able to rapidly shoot multiple stingers like a machine gun.
  • Unexplained Recovery: She gets buried alive inside of a volcano moments before it erupts, yet returns in "Monster Wars", seemingly none the worse for wear.

    Santa Marta Plant 
https://static.tvtropes.org/pmwiki/pub/images/santa_marta_plant.png

Debut: "Hive"

After a volcano erupted on the island resort of Santa Marta, H.E.A.T. was sent to investigate reports of giant carnivorous plants that had attacked a group of looters attempting to steal valuables from the resort's hotel. During their investigation, the team was repeatedly attacked by these mutated plants, which Elsie reasons were created by irradiated ash caused by the island's former use as a secret nuclear testing site. The plants in turn were responsible for creating the island's giant bees, who then further spread the mutation to other plants. Both the plants and bees were killed off when the volcano erupts again.


  • Botanical Abomination: They are giant vines that actively tunnel underground and attack anyone that gets close.
  • Combat Tentacles: Or more accurately, combat vines. They're primary means of attack is the bind anything that gets within grabbing range. The vines are even strong enough for a large number of them to restrain Godzilla.
  • Food Chain of Evil: Their pollen acts as a food source (and mutagen) to the island's giant bees, who in turn spread the mutation to other plants.
  • Man-Eating Plant: While they don't explicitly try to eat anyone, the fact that they seem to deliberately target living things seems to indicate that they are carnivorous in nature.

    Quetzalcoatl 
https://static.tvtropes.org/pmwiki/pub/images/quetzalcoatl_15.png

Debut: "Bird of Paradise"

A giant prehistoric bird of prey, Quetzalcoatl appears in a Mayan step pyramid and begins attacking nearby villages. H.E.A.T. attempts unsuccessfully to subdue the monster until it carries off Elsie. The rest of the team theorizes that Quetzalcoatl, or "Q" as they nickname it, has a nest nearby. After they locate the nest in a volcano, H.E.A.T. signals Godzilla to aid them while they rescue Elsie. Quetzalcoatl is defeated and it and its young are sent plummenting into the volcano.


  • Breath Weapon: Fires a large stream of fire.
  • Disney Villain Death: Q and her offspring were last seen plummeting back into the volcano. Given that the species had survived centuries inside the volcano, it's possible they are fine.
  • Expy: Of Rodan.
    • The babies are very likely based on the Velociraptors from Jurassic Park, even using the same sound effects.
  • Extremophile Lifeforms: It's feathers have a molecular composition similar to silicon, allowing it to withstand temperatures of up to 2,000° F. As a result, Q is able to nest comfotably inside an active volcano.
  • Giant Flyer: Q is a gigantic prehistoric bird of prey.
  • Kidnapping Bird of Prey: It carries off Elsie and attempts to feed her to its young.
  • Mama Bear: Q is only attacking humans in order to protect her babies or feed them.
  • No-Sell: Its feathers have a silicate coating that shield them from the extreme temperatures of volcanos. This also protects her from conventional weaponry and Godzilla's atomic breath.
  • Playing with Fire: Q is able to breath streams of fire as a ranged attack.
  • Prehistoric Monster: It resembles a giant Archaeopteryx or other prehistoric bird
  • Shout-Out: It has many similarities to the Firebird from The Godzilla Power Hour: both are female expies of Rodan, nest in volcanos, and come into conflict with Godzilla while trying to care for its young.
  • To Serve Man: Q carries off Elsie as food for her chicks.

    Nessie 
https://static.tvtropes.org/pmwiki/pub/images/nessie.png

Debut: "Dead Loch"

Nick and Elsie see a news report from Scotland detailing an alleged attack by the Loch Ness Monster, which Nick dismisses as a hoax meant to drum up tourism. However, when H.E.A.T. investigates the lake, they soon learn that Nessie is very real, with Nick and Elsie theorizing it is a prehistoric sea creature that has been living in Loch Ness since the lake became separated from the ocean. Later, the team discovers that the institute attacked by Nessie is harboring her offspring. After Godzilla frees her baby, the two monsters part ways amiably.


  • Enemy Mine: Though Nessie and Godzilla fight at first, once he realizes she's trying to save her baby, he quickly helps her in the rescue.
  • Expy: Of Manda, being a sea monster that resembles a serpentine dragon.
  • Gigantic Adults, Tiny Babies: Nessie's baby is much closer to humans, size-wise, than its mother is.
  • Informed Species: Stated to be a mosasaur, but looks more like a generic sea serpent than any real animal, never mind a mosasaur.
  • Mama Bear: Nessie's attacks on Dr. Trevor's facility are because he's holding her baby captive for scientific purposes.
  • Sea Monster: Well, technically she's a lake monster. That doesn't change the fact that she's a Godzilla-sized sea serpent that suddenly goes on the warpath when her baby is taken from her.
  • Seldom-Seen Species: Nick calls her a mosasaur, a species not often seen before Jurassic World made it iconic. That probably had something to do with why it does not remotely resemble a mosasaur.
  • Stock Ness Monster: The one and only, though she's more of a sea serpent type than the usual plesiosaur.
  • Riding into the Sunset: In a rarity for this series, Nessie and her baby are allowed a happy ending and remain in the Loch.

    Robo-Yeti 
https://static.tvtropes.org/pmwiki/pub/images/robo_yeti.png
https://static.tvtropes.org/pmwiki/pub/images/robo_yeti_2.png

Debut: "Competition"

A giant mechanical ape, the Robo-Yeti first appears to be another mutation until its fur and skin are burned away by Godzilla's atomic breath. It is then revealed to be an anti-mutation weapon built for the JSDF. Although antagonistic towards Godzilla due the mistaken belief that he is responsible for several hikers going missing, it is soon confronted by the actual perpetrator, the King Cobra. After being quickly defeated by the gigantic snake, the Robo-Yeti is quickly repaired and teams up with Godzilla to pursue the King Cobra to Tokyo, although the King Cobra quickly destroys it yet again.


  • Animal Mecha: A giant mechanical ape disguised to look like a monstrous yeti.
  • Barbarian Longhair: The Yeti's furry disguise includes a long mane of hair on top of its head.
  • Bare-Fisted Monk: Initially, the Robo-Yeti fights Godzilla solely through hand-to-hand combat, showcasing its martial arts prowess. Once it's cover is blown, however, the robot drops all pretense and just switches over to its weapons systems.
  • Bigfoot, Sasquatch and Yeti: It's meant to resemble a kaiju-sized yeti, until Godzilla destroys its disguise.
  • Cranial Processing Unit: The Robo-Yeti is incapacitated when the King Cobra repeatedly bites its head, damaging its processing unit and requiring a replacement circuit card from N.I.G.E.L.
  • Curb-Stomp Battle: It never goes well for Robo-Yeti whenever it goes up against King Cobra, with the most it manages to do was yank the snake off Godzilla when it was trying to crush him, allow Godzilla enough time to recover and defeat it.
  • Enemy Mine: Though it fights Godzilla at first, once King Cobra appears on the scene, the machine becomes a reluctant ally to the lizard.
  • Humongous Mecha: Created by Dr. Ifukube to defend Japan from giant monsters.
  • King Kong Copy: It is meant to look like a giant ape
  • Macross Missile Massacre: Although not to the extent of most giant robots, the Robo-Yeti does pack a large payload of missiles in its chest.
  • Mythology Gag: Robo-Yeti is initially covered in a fake skin to make it seem as though it is a real gigantic primate of some kind, just like Showa Mechagodzilla was disguised as Godzilla in Godzilla vs. Mechagodzilla. Also like Mechagodzilla, Robo-Yeti's disguise is ruined thanks to Godzilla's atomic breath.
    • The idea of a giant primate fighting Godzilla goes all the way back to "King Kong Vs. Godzilla," and the mechanical nature of Robo-Yeti might be a shout-out to Mechanikong.
  • Off with His Head!: Its second encounter with King Cobra, it gets constricted so hard that its head breaks off, along with one of its arms.
  • Red Eyes, Take Warning: In both of its forms, it has red eyes. After it is revealed to be a robot, it's eyes also have a noticeable glow.
  • Robotic Reveal: After Godzilla sets its fur on fire with his atomic breath, the Robo-Yeti emerges from the flames, showing off his true form.
  • Shock and Awe: Robo-Yeti can shoot electric cables from its hands to electrocute opponents (similar to Heisei Mechagodzilla's Shock Anchor).
  • Shout-Out: In addition to the obvious King Kong references, the skeletal appearance of the Robo-Yeti after having its skin burned off is one for The Terminator.
  • Walking Armoury: In addition to its mastery of the martial arts, the Robo-Yeti has built-in missile launchers, electrified cables it can launch from its hands, and nozzles in its fingertips (while these were only used to spray a chemical to counteract King Cobra's adhesive spit, it's not hard to imagine these could be used for more offensive liquids).
  • We Can Rebuild Him: After the King Cobra is defeated, Dr. Ifukube asks for Craven's advice on rebuilding the Robo-Yeti.
  • The Worf Effect: Despite managing to get the better of Godzilla when they first fight, it ends up being reduced to this in the fights with the King Cobra.

    King Cobra 
https://static.tvtropes.org/pmwiki/pub/images/kingcobra.png

Debut: "Monster Wars: Part 1" [First appearance by release date]; "Competition" [First chronological appearance]

The King Cobra first appeared near Mount Fuji, abducting local hikers. Both H.E.A.T. and the JSDF investigated the disappearances, leading to conflict between Godzilla and the JSDF's Robo-Yeti, before King Cobra appeared, blinding Godzilla and disabling the mechanical ape. After making its way to Tokyo, it is again confronted by Robo-Yeti and Godzilla, leading to the serpent's defeat. King Cobra would later reappear in the "Monster Wars" trilogy as part of the Leviathan Alien's monster army, who deployed him to attack Paris. After their control beacon was disabled, King Cobra rebelled against its former masters, but was quickly incapacitated. It was later captured and became part of the Mutant Research Facility on Monster Island for the remainder of the series.


  • Bad Future: In an alternate future in which the world was overrun by genetically engineered monsters known as Dragmas, King Cobra was released from Monster Island to fight them, but was slain in battle against the creatures.
  • Curb-Stomp Battle: King Cobra takes out Robo-Yeti pretty quickly in both of their fights, the second time squeezing the machine so hard that its neck breaks and its arm pops off.
  • Off-Model: The show would be horribly inconsistent with King Cobra's size. In one scene, he would be massive enough to tower over Godzilla and completely envelope him in his coils. In another, he'd be small enough for Godzilla to bite down on his neck and toss around like a rag doll. It thankfully didn't happen too often, but when it did, it was jarring.
  • Recurring Character: Comes back for the "Monster Wars" trilogy, then later "SCALE."
  • Reptiles Are Abhorrent: He's a gigantic cobra.
  • Spikes of Villainy: It has spikes extending from both sides of its hood, and another row of spikes running down its spine.
  • Super Spit: He can spray an adhesive gunk from his mouth. He puts this to good use when he blinds Godzilla for almost the entirety of the episode.
  • To Serve Man: It attacks people and is sticking them to the walls of its lair as a food source for winter.
  • Tunnel King: Surprisingly adept at burrowing for a cobra.

    The Giant Bat 
https://static.tvtropes.org/pmwiki/pub/images/giant_bat.png

Debut: "Monster Wars: Part 1"

The Giant Bat appears in Nigeria, terrorizing the countryside as it raids livestock from local farms. Nick Tatopolous and Godzilla arrive in Nigeria to confront it, but it eventually flies off when the Leviathan Aliens take control of it. Monique and Randy pursue it in the Heat-Seeker, eventually following it to Site Omega, where they discover that most of Earth's monsters have been assembled there. The Bat is deployed to Paris alongside King Cobra. After the Leviathan aliens' control beacon is disabled, the Giant Bat began to perceive the alien spaceships as intruders on its territory and attacked. Eventually, it returned to Site Omega and was defeated by Cyber-Godzilla. Once the Leviathan Aliens' invasion was defeated, the Giant Bat was captured and became part of the Mutant Research Facility on Monster Island for the remainder of the series.


  • Ambiguous Situation: The last time the Bat was seen, he was laying on the ground motionless following a battle against both Godzilla and Skeetera making it unknown whether or not he was merely unconscious or killed from the fight. While Audrey states that the mutations have been secured, only footage of C-Rex and King Cobra were shown back in their habitats.
  • Bat Out of Hell: Its a giant mutated bat large enough to carry off two full-grown oxen.
  • Curb-Stomp Battle: The Bat is the only of the Earth monsters aside from Godzilla to stand up against Cyber-Godzilla... and he is immediately defeated when Cyber-Godzilla reflects his own sonic scream back at him.
    Elsie: "Yippee."
  • Exactly What It Says on the Tin: He's a giant bat.
  • Expy: Of the bat kaiju Bagorah from Dark Horse Comics Godzilla, King of the Monsters series, having similar physical features and a sonic attack.
  • Giant Flyer: Naturally.
  • Logical Weakness: Being a bat, it is highly dependent on its echolocation, so anything that compromises it seriously effects its ability to navigate.
  • Make Me Wanna Shout: The Bat can unleash sonic screams as his main form of attack. In "SCALE," we see that the military has fitted him with an electronic collar so that he can't use his screams while on Monster Island.
  • Recurring Character: Comes back for "SCALE."

    Cyber-Godzilla Sr. 
https://static.tvtropes.org/pmwiki/pub/images/cyber_godzilla_2.png

Debut: "New Family: Part 1" [as Godzilla]; "Monster Wars: Part 2" [as Cyber-Godzilla]

After having been killed at the end of Godzilla (1998), Godzilla Sr.'s body was transported to Sandy Point Military Base. When the Leviathan Aliens launched their plan to conquer the Earth, it was resurrected as Cyber-Godzilla, and immediately came into conflict with his son. However, his son hesitated to attack him, allowing the Leviathan Aliens to place Godzilla under mind control. The two monsters travelled to Site Omega with the rest of Earth's monsters, with Cyber-Godzilla being deployed to Tokyo. After the Leviathan Aliens' mind control beacon was destroyed, Cyber-Godzilla was the only monster to remain under alien control and was recalled to Site Omega to take out H.E.A.T. Once there, it easily defeats the Giant Bat and again confronts its son, who turns against him and kills Cyber-Godzilla once and for all.


  • Archnemesis Dad: He's Godzilla Jr.'s biological parent, but the two eventually become mortal enemies.
  • Artificial Limbs: His right arm is completely replaced by a robotic limb.
  • Attack Reflector: He has a dish built into his chest that is able to reflect the Giant Bat's sonic attack back at him.
  • Back from the Dead: He's the Godzilla from the film the series spun off of, and was killed at the finale of said film. The Leviathan aliens resurrect him as a cyborg in "Monster Wars."
  • Body Horror: Aside from his cynernetic implants, his body is visibly decaying. His spines are grayed, his body is browning, and a lot of his teeth are missing. His roar has degenerated into an undead moan. It is easier to see how different he is from his son when they are in the same frame.
  • Breath Weapon: Somehow has one when he became a cyborg. He didn't actually have one in the film (where it was more of a wind blast roar). Also, it's the traditional blue compared to his son's green.
  • Came Back Strong: Is much stronger than it originally was due to the cybernetic enhancements.
  • Curb-Stomp Battle: Cyber-Godzilla defeats the Giant Bat in a single blow. He's on the receiving end of one from his son, barely even managing to touch him.
  • Darth Vader Clone: Hilariously enough, he hits most of the main points. He's an Evil Counterpart to Godzilla, raised by an alien empire to serve as their Dragon, he convinces the heroic Godzilla to his side by revealing his parentage to Junior, and he's a heavily armored cyborg to boot.
  • The Dragon: To the aliens, proving to be their strongest monster in their invasion. Since it was controlled through cybernetic implants he stayed on their side when the mind control over Earth's monsters was broken.
  • Everyone Calls Him "Barkeep": Cyber-Godzilla is never referred to by that name in the series. The Leviathan aliens simply refer to him as "the cyborg", while Nick calls him "Godzilla's daddy".
  • Expy: Of Mechagodzilla. Ironically, Kiryu of Godzilla Against Mechagodzilla seems to be based on him or is just coincidentally similar in concept.
    • Ironically, he serves as an expy of King Ghidorah. He serves as the Leviathan Aliens' most powerful asset in "Monster Wars" (a Whole Plot Reference to Destroy All Monsters), fulfilling the same role as the Showa King Ghidorah, and he is a Cyborg built from the body of a dead Kaiju, just like Mecha-King Ghidorah in the Heisei series.
  • Family-Unfriendly Death: His fight with Godzilla ends with him getting his arm torn off, his chest ripped open and the vital circuitry inside ripped out.
  • Final Boss: Of the video game Godzilla: The Series- Monster Wars.
  • Flawed Prototype: In spite of his upgrades, Cyber-Godzilla is clearly a weaker monster than his son, as he is defeated after failing to land a single blow on Godzilla, even with assistance from the Leviathan aliens.
  • Gender Flip: Despite being referred to as male in the movie and the animated series, the video game Godzilla: The Series- Monster Wars specifically refers to Cyber-Godzilla as female.
  • Hell Is That Noise: His roar is deeper and more mechanical than his son's, the end result sounding more like an undead moan than anything else.
  • Logical Weakness: Given that his body appears to have partially decayed, it should come as no surprise that he doesn't have the same mobility as his son.
  • Long-Range Fighter: All of his weapons are designed to attack from a distance. When he does try to engage his son in melee combat, the younger Godzilla is able to easily outmaneuver him.
  • Luke, I Am Your Father: It uses its relation to Godzilla Junior to manipulate him more than once.
  • Macross Missile Massacre: Although he uses them more conservatively than his Mechagodzilla expies, with beam weapons being the preferred choice.
  • Mythology Gag: His atomic breath is blue, like the classic Godzilla, as opposed to his son's green. He is sent to destroy Tokyo, the scene of most Godzilla films.
  • Ninja Pirate Zombie Robot: Its an undead mutated iguana cyborg.
  • Reforged into a Minion: The Leviathan Aliens orchestrate his resurrection as a cyborg to serve as their most powerful weapon against Earth's forces.
  • Took a Level in Jerkass: In the film, Godzilla Sr. was just a mutated animal just trying to live out it's natural life cycle, generally ran from a fight when it could, and only deliberately attacked people when provoked. After being rebuilt as a cyborg, he intentionally causes destruction under the Leviathan aliens' command.
  • Truer to the Text: Ironically, becoming a cyborg actually addressed many of the issues that made him "Godzilla In Name Only": the lack of atomic breath, his tendency to run from a fight, and his vulnerability to conventional weaponry.
  • Undead Abomination: The body of giant mutated iguana brought back to life (with the Body Horror that implies) with cybernetic enhancements specifically to be The Dragon to an alien invasion.
  • Unfriendly Fire: His robotic arm is accidentally blown off by a Leviathan fighter aiming for Godzilla Junior.
  • Walking Armoury: Not to the extent of most mechanical monsters, Cyber-Godzilla still has multiple missile launchers attached to its dorsal plates and a cybernetic dish on its chest that can reflect sound-based attacks back at their source. It also has atomic breath, something it lacked pre-cybernetics.
  • We Can Rebuild Him: After being shot down by F-18's on the Brooklyn Bridge, a group of scientists controlled by the Leviathan aliens rebuild him as a cyborg.

    Ice Borer 
https://static.tvtropes.org/pmwiki/pub/images/ice_borer.png

Debut: "Freeze"

The Ice Borers are mutated moles that burrow through the Antarctic ice in search of food to fuel their high metabolism. They first appear to attack a group of researchers searching for oil deposits in Antarctica. Although the disappearances are blamed on geological tremors, Nick suspects a mutant is responsible and H.E.A.T. travels to investigate.


  • Big Eater: The Ice Borer's extremely high body temperature requires them to constantly seek out food to keep up with their high metabolism.
  • Expy: Possibly of Baragon, given that it is a burrower with heat-based powers.
  • Extreme Omnivore: When the HEAT team arrives, any trace of animal life are all gone.
  • Irony: H.E.A.T. uses improvised freeze rays to defeat the Ice Borers, creatures specially adapted to life in the Antarctic. Randy even lampshades the absurdity of the plan.
  • Kill It with Ice: H.E.A.T. determines that the Ice Borer's abnormally high body temperature is crucial to their survival, so they create liquid nitrogen weapons to lower their temperature.
  • Kryptonite Factor: The cold.
  • Misplaced Wildlife: The Ice Borers are mutated moles, animals not native to Antarctica.
  • My Blood Runs Hot: They are able to rapidly tunnel through the ice due to their unusually high body temperatures. H.E.A.T. is able to weaken them using liquid nitrogen to cool their bodies off, making them vulnerable to the cold.
  • Shout-Out: Their ability to tunnel and their tendency to drag their prey underground are likely a reference to the Graboids from Tremors.
  • Tunnel King: They can rapidly burrow through the ice using their own body heat.
  • Wormsign: The first indication of their approach is the snow shifting while they pass beneath it.

    Giant Mutant Termite 
https://static.tvtropes.org/pmwiki/pub/images/giant_mutant_termite.png

Debut: "Bug Out"

H.E.A.T. is sent to South America by the United Nations to discover what is destroying large areas of the Amazon Rainforest. They discover a hive of giant mutated termites are responsible and are consuming trees at a rate that will completely level the entire forest within three weeks if something is not done to stop them.


  • Big Creepy-Crawlies: They're gigantic termites. The soldiers are roughly the size of horses, while the queen is as large as a house.
  • Expy: They are very similar to the Queen Bitch and her termite-like offspring from the unmade sequel to Godzilla (1998). Possibly unintentional as the episode aired while GODZILLA 2 was still in pre-production (Roland Emmerich and Dean Devlin would both drop out of the project the same month, with the film being scrapped shortly afterwards).
  • Large and in Charge: The queen is significantly larger than the other termites.
  • Let's You and Him Fight: Craven uses ultrasonic transmitters to simulate an attack signal, causing the termites to turn on one another long enough for H.E.A.T. to enter the termite mound and set up a bomb in the egg chamber.
  • Termite Trouble: They threaten to wipe out the entire Amazon Rainforest in a few weeks if not stopped.
  • Zerg Rush: What they lack in size (compared to other monsters anyway), they make up for in sheer numbers. A swarm of soldiers is even able to force Godzilla into temporarily retreating.

    Giant Mutant Widow Spider 
https://static.tvtropes.org/pmwiki/pub/images/giant_mutant_widow_spider.png

Debut: "Web Site"

The Giant Mutant Widow Spider is a giant mutant black widow with thousands of tarantula-sized offspring that have largely overrun a tropical island, threatening a military base on the island.


  • Death by Irony: The Widow and her babies ends with them being paralyzed for good.
  • Expy: Of Kumonga and other Giant Spiders.
  • Giant Spiders: The babies range in size from slightly larger than a tarantula to roughly human-sized. The adult is nearly as large as Godzilla.
  • Kryptonite Factor: The pollen of one local flower instantly paralyzes them. H.E.A.T. fashions a bomb filled with the flowers to take out all of the spiders while they're all in one place.
  • Mother of a Thousand Young: She has hundreds, if not thousands, of offspring and can reproduce more asexually, creating an entire army of mutant spiders.
  • No-Sell: According to Elsie, the spiders are immune to most pesticides.
  • The Paralyzer: They render their prey immobile with their venomous bites to eat them.
  • Projectile Webbing: What else would you expect from a gigantic spider monster?
  • Shout-Out: Ironically, the climax of the episode is basically the same as that of the movie: the heroes trying to locate the nest of a mutant that reproduces asexually to take out the offspring before they can escape and overpopulate the rest of the world.
  • Spider Swarm: The infants attack in large numbers, quickly overwhelming a group of well-armed soldiers.
  • Truly Single Parent: The Widow reproduces asexually.

    Chameleon 
https://static.tvtropes.org/pmwiki/pub/images/chameleon_0.png

Debut: "An Early Frost"

The Chameleon is a clone of Godzilla created by Cameron Winter to frame the real Godzilla and kill him after public opinion turned against him.


  • Belly Mouth: The Chameleon has a large, gaping mouth across its upper torso.
  • Bioweapon Beast: Created from Godzilla's DNA to frame him and ultimately kill him so that Cameron Winter could sell others like him as living weapons.
  • Body Horror: Chameleon's has a head consisting of three finger-like appendages with eyes on the sides, and a gaping mouth on his chest.
  • Evil Knockoff: Explicitly stated to be cloned from Godzilla for the purpose of framing him and then killing him.
  • Frame-Up: Created from Godzilla's DNA for the express purpose of framing him.
  • Hollywood Chameleons: Able to blend in with its environment so well that it becomes practically invisible.
  • Mythology Gag: The Chameleon's signature ability is his pseudo-invisibility, an ability given to Godzilla in early drafts of the film.
  • No-Sell: Due to being created as an anti-Godzilla weapon, he is impervious to Godzilla's atomic breath.
  • Prehensile Tail: Just like its namesake, the Chameleon can use its tail as an extra limb to grasp objects and opponents with.
  • Shout-Out: Chameleon taking on Godzilla's appearance in order to frame him is likely a nod to Mechagodzilla's disguise in Godzilla vs. Mechagodzilla.
  • Spikes of Villainy: In addition to the same fin-shaped scutes as Godzilla, Chameleon has a number of spikes and bony protrusions extending from its arms.
  • Taken for Granite: After Philippe injects with the special serum meant for Godzilla.
  • Voluntary Shapeshifter: Switches between its own monsterous form and imitating Godzilla.

    DNA Mimic 
https://static.tvtropes.org/pmwiki/pub/images/dna_mimic_elsie_chapman.png

Debut: "Trust No One"

The DNA Mimic is a shapeshifting mass of pure genetic material created by Dr. Anton Fleurie as part of a hybridization experiement. It was left abandoned in the doctor's lab in the jungles of French Guinea. After being inadvertently released by a treasure hunter years later, it began roaming the jungles in search of its counterpart. H.E.A.T. is tipped off about the creature's existence by Phillipe Roaché and begin investigating the laboratory. While Monique is separated from the group, the DNA Mimic attacks her and later uses her form to coerce Randy into locating the other Mimic. It continues to shift forms between the different members of H.E.A.T. to keep them fighting amongst themselves while it searches for its mate. H.E.A.T. discovers that if the two combine, they will be able to reproduce, potentially replacing humans as Earth's dominant species. The Mimic is able to find the second barrel and merge with its mate, though Godzilla arrives to challenge it before it can do any harm. Nick is able to hit the Mimic with a dart containing an anticellular mutagen, which weakens it long enough for Godzilla to finish it off.


  • All Your Powers Combined: In addition to taking on their appearances, the DNA Mimic can replicate the skills and physical abilities of people it imitates, such as Craven's programming skills.
  • Blob Monster: In its natural form, the Mimic is nothing more than a gelatinous grey mass.
  • Ditto Fighter: It is ably to copy the appearance and abilities of everything it touches, making it quite possibly the most versatile opponent Godzilla faces in the series.
  • Glamour Failure: H.E.A.T. discovers that the DNA Mimic's body temperature is higher than a normal human, allowing them to identify Elsie as the Mimic in disguise.
  • It Can Think: As the episode progresses, the Mimic reveals it has a great display of tactical thinking, mechanical skills, as well as manipulation skills, possibly due to inheriting memories from its donors.
  • Kill and Replace: It tries this on Elsie but failed.
  • Kryptonite Factor: Elsie develops a chemical mutagen specifically designed to rip the creature apart at the genetic level. While this doesn't kill the Mimic immediately, it does weaken it enough for Godzilla to finish it off.
  • Miracle-Gro Monster: After the Mimic merges with its mate, it goes morphing into normal-sized creatures into Godzilla-sized ones.
  • Multiple Head Case: After being hit with a dart containing anticellular mutagen, the Mimic loses control, assuming the form of a giant, deformed two-headed copy of Elsie.
  • Sealed Evil in a Can: At the start of the episode, the DNA Mimic is sealed in a barrel in a backroom of a remote laboratory hidden in a South American jungle before a treasure hunter accidentally releases it. Its counterpart is in a similar barrel at the bottom of a river several miles away.
  • Shout-Out: The DNA Mimic is an obvious homage to The Thing.
  • Snakes Are Sinister: It uses the form of an anaconda to nearly kill Monique and absorb her DNA. After merging with its mate, its anaconda form is large enough to battle Godzilla.
  • Unstable Genetic Code: It's stated to be composed of pure DNA, allowing it to change into anything whose DNA it absorbs.
  • Voluntary Shapeshifting: It can take the appearance of anyone or anything whose DNA it absorbs through touch. Over the course of the episode, it assumes the forms of all five members of H.E.A.T., a rottweiler, anaconda, condor, panther, monkey, alligator, giant piranha, a giant bee, and Godzilla himself.

    Techno-Sentient 
https://static.tvtropes.org/pmwiki/pub/images/techno_sentient_form_3.png

Debut: "Juggernaut"

The Techno-Sentient is a mysterious organism from outer space that has the ability to fuse itself with any mechanical device it comes into contact with. After absorbing a number of electronics and construction equipment, it grows to Godzilla-like proportions. H.E.A.T. discovers it is tapping into the Internet to learn about humans, Earth, and the location of weapons of mass destruction. They pursue the monster to a nearby military base, where the Tecnho-Sentient is attempting to launch a nuclear missile to trigger a nuclear armageddon. Godzilla is able to pin the Techno-Sentient to the missile, which Randy redirects to explode outside the Earth's atmosphere, destroying it.


  • And I Must Scream: Get sent into outer space alongside the missile it tried to use.
  • Chainsaw Good: Attempts to kill Craven with a circular saw.
  • Combat Tentacles: It can extend tentacle-like cables to grab nearby machinery to be incorporated into its body or to restrain its adversaries.
  • Expy: Of Berserk, a scrapped kaiju from the unmade 1993 film, Godzilla vs. Berserk, which would eventually be reworked into Godzilla vs. Mechagodzilla II. Both Berserk and the Techno-Sapient are alien lifeforms that assimilate machinery into themselves.
  • From Nobody to Nightmare: In just a few hours, it goes from an alien lifeform the size of a child's toy into a Godzilla-sized mass of living machinery that comes within seconds of setting off a global nuclear war.
  • Hoist by His Own Petard: It ends up being destroyed by the same nuclear missile it was attempting to use to start World War III after Godzilla pins the Techno-Sapient's body to the missile.
  • Hooks and Crooks: After incorporating a construction crane into its body, the Techno-Sapient uses it as an improvised grappling hook and flail.
  • An Ice Person: Assimilating a refrigerator into its body allowed it to launch ice shards as projectile weapons.
  • It Can Think: Compared to most of the monsters in this series, the Techno-Sapient is very cunning, using the Internet to locate a nuclear missile silo and targeting Bagdad in an attempt to start World War III.
  • Miracle-Gro Monster: It continuously grows as it assimilates more machinery, going from the size of a RC car to as large as an ICBM in a relatively short period of time.
  • No-Sell: Despite being hit by several missiles, the Techno-Sentient is able to assimilate them into its body before they have the chance to detonate.
  • Shoulder Cannon: It briefly gains one when it assimilates a tank.

    D.R.A.G.M.A. 
https://static.tvtropes.org/pmwiki/pub/images/dragma.png

Debut: "Future Shock"

D.R.A.G.M.A. are a species of manmade monsters created by Dr. Jonathon Insley to take mankind back to simpler times and avoiding civilization's increasing reliance on technology. When H.E.A.T. gets drawn into an alternate future, the D.R.A.G.M.A. have overrun the planet, wiping out all of the mutations on Earth, including Godzilla, and reducing the human race to a few isolated pockets of survivors. H.E.A.T returns to the present and locates Insley and destroys his work, killing the juvenile D.R.A.G.M.A.s before they can mature and threaten the world.


  • Alien Blood: According to Mendel, they have sulfuric acid as blood.
  • Dragons Are Demonic: They resembe dragons mixed with a Triceratops, and are quite possibly the deadliest adversary Godzilla faces (if only because they actually succeeded in killing him).
  • Explosive Breeder: One on one, the D.R.A.G.M.A. aren't the toughest monsters around, considering ordinary humans with advanced weaponry can take them out. However, they breed like rabbits, rapidly overrunning the planet through sheer weight in numbers.
  • Expy: Of Destroyah.
  • Fun with Acronyms: Their name actually stands for Democratic Resurgence Against Global Mechanized Armageddon (D.R.A.G.M.A), although the characters don't discover this until the end of the episode.
  • Hero Killer: In a Bad Future, they killed Godzilla, though not until took a lot of them with him.
  • Immune to Bullets: Zigzagged- the adults are immune to most forms of conventional weaponry (though given Godzilla was supposedly able to kill at least some of them, they aren't completely invincible). As infants, however, their hides are much thinner and more susceptible. Alternatively, they are mentioned to adapt quickly, and the ones from the present-day haven't adapted to modern weapons yet.
  • Living Weapon: They were created to be this.
  • Not So Invincible After All: Despite being the most destructive creatures in the series (given they wiped out much of humanity and all other monsters), they are still susceptible to the high-powered energy weaponry that Future-Mendel's resistance fighters wield.
  • Stock Dinosaurs: They seem to resemble a cross between a Triceratops and a dragon.
  • Turned Against Their Masters: The D.R.A.G.M.A.s show absolutely no loyalty to their master; in the future, Hicks relates to the H.E.A.T. team that by the time the military learned Insley was responsible for the outbreak, he was already long dead at the hands of his creations. In the present, when Insley orders the D.R.A.G.M.A.s to kill the team, he only succeeds in drawing their attention onto him.
  • Utopia Justifies the Means: They were created by Dr. Jonathan Insley, head of the Democratic Resurgence Against Global Mechanized Armageddon project (D.R.A.G.M.A), who believed mankind's overreliance on technology would bring about its extinction, and wanted to use his creations to force mankind to embrace a more simpler time. Unfortunately, Insley didn't consider a way to call his creations off once they'd completed their task, an oversight that resulted in his own death, countless others and the near extermination of mankind.
  • Zerg Rush: Alone they don't appear much stronger than any of the other kaiju shown in the series, but the issue is that even at the beginning there are dozens of them.

    Giant Water Beetle 
https://static.tvtropes.org/pmwiki/pub/images/giant_water_beetle.png

Debut: "Cash of the Titans"

The Giant Water Beetle is a mutation that serves as a pawn of millionaire promoter Maximilian Spiel. He first appears attacking H.E.A.T. headquarters to keep the team distracted while Spiel's mercenaries abducted Godzilla. Later, it is encountered by Monique and Randy on Spiel's island and pursues them while Godzilla battles Rhinosaurus. After Rhinosaurus is defeated, Godzilla turns its attention on the beetle, throwing it into the arena's control tower, pinning Spiel under its bodyweight.


  • Attack Animal: Maximilian Spiel sent the Giant Water Beetle to attack H.E.A.T. headquarters as a diversion. After Godzilla is successfully captured, the Beetle is called off by the sound of a foghorn. Later, it is deliberately released into the arena to kill the members of H.E.A.T. trying to free Godzilla.
  • Big Creepy-Crawlies: A water beetle the size of a large vehicle.
  • Big Guy, Little Guy: The Little Guy to Rhinosaurus' Big Guy, as while it's not large enough to take on other mutations, it is still large enough to be a threat to human adversaries. It is also smart enough to respond to a signal by its human masters, while Rhinosaurus never has any opportunity to show any kind of intelligence.
  • Kick the Son of a Bitch: While its a dangerous mutant, H.E.A.T. doesn't mind it having Maximilian Spiel at its mercy.
  • Poisonous Person: It releases clouds of ammonium nitrate gas from the pores on its head.

    Rhinosaurus 
https://static.tvtropes.org/pmwiki/pub/images/rhinosaurus.png

Debut: "Cash of the Titans"

Rhinosaurus is one of several mutations held captive by wealthy promoter Maximilian Spiel to participate in monster fights. It serves as Godzilla's opponent in the arena, though Godzilla is able to defeat it in a single blow after Craven disables the spotlights blinding Godzilla.


  • Badass Normal: It lacks any special abilities, but is a formidible mutation with a massive horn and thick, durable hide that allow him to go toe-to-toe with Godzilla for a time.
  • Big Guy, Little Guy: The Big Guy to the Giant Water Beetle's Little Guy, being large enough to go one-on-one with Godzilla while the Beetle chases H.E.A.T. around the arena.
  • Curb-Stomp Battle: It has Godzilla on the ropes for most of the fight only because Godzilla is being blinded by Maximilian Spiel's spotlights. Once Craven destroys the spotlights, Godzilla knocks Rhinosaurus out in a single Tail Slap.
  • Exactly What It Says on the Tin: It resembles a cross between a rhinoceros and a dinosaur.
  • Horn Attack: As a mutated rhino with no special abilities, its primary means of attack is to gore its opponent with its horn. It is shown to be tough enough to drive his horn through several meters of concrete with little effort (though this broke off several meter-long splinters of horn).
  • Rhino Rampage: It's a giant mutated rhinoceros forced to do combat against other mutations.
  • Spikes of Villainy: Rhinosaurus has a series of bony spikes running down its spine.

    Shrewster 
https://static.tvtropes.org/pmwiki/pub/images/shrewster_2.png

Debut: "The Twister"

The Shrewster is a mutated shrew encased in a tornado created at an accident at a power plant. It eventually made its way to New York, where it attracted the attention of H.E.A.T., who eventually developed a device to depressurize the Shrewster's tornado. After being defeated by Godzilla, the Shrewster was slated to be taken to Monster Island.


  • Big Eater: Elsie points out that shrews eat three times their own body weight every day to keep up with their high metabolism. The Shrewster uses its tornado as a means of drawing food to it.
  • Blow You Away: Shrewster is able to surround itself in a tornado as its primary means of attack, defense, and locomotion.
  • The Cameo: Appeared in another episode; apparently he never got to Monster Island and was actually captured to take part in mutant fights.
  • Extreme Omnivore: It will gladly eat anything that its tornado draws inward: trees, vehicles, Nick Tatopolous, etc.
  • Shout-Out: Its ability to conceal itself in a tornado, coupled with its Big Eater tendencies, is likely a reference to the Tasmanian Devil from Looney Tunes.
  • Tornado Move: It creates a giant tornado around itself.

    Skeetera 
https://static.tvtropes.org/pmwiki/pub/images/skeetera.png

Debut: "S.C.A.L.E."

Skeetera is a mutated mosquito that attacked Miami, where she was attacked by Godzilla. Despite intervention from the eco-terrorist group S.C.A.L.E., Skeetera was eventually subdued by Godzilla and transported to Monster Island. Not long after it arrived, S.C.A.L.E. arrived to free the monsters contained on the island. Skeetera began attacking the other mutations, drinking their blood and copying their abilities. Godzilla finally managed to defeat her by knocking her into a nearby power plant.


  • Big Creepy-Crawlies: A giant, energy-sucking mosquito.
  • Curb-Stomp Battle: A four-way battle between Skeetera, C-Rex, King Cobra, and the Giant Bat ends up with Skeetera pretty much kicking everyone's backside.
  • Giant Flyer: She's big to begin with, and she keeps getting larger whenever she feeds on the blood of other mutations.
  • High-Voltage Death: Godzilla defeats Skeetera by smacking her with his tail directly into the power plant on Monster Island. While it's never outright stated that she was killed by it, we don't see her up and about with the other mutations at the end of the episode.
  • Miracle-Gro Monster: Whenever she drinks a fellow mutation's blood, Skeetera increases in size.
  • Mosquito Miscreants: She's a giant mosquito that feeds on other mutations, absorbing their powers. This requires Godzilla and H.E.A.T. to put her down.
  • Power Parasite: In addition to getting bigger, drinking a mutation's blood also grants Skeetera any special powers her victim may have, from Godzilla's atomic ray to King Cobra's adhesive spit.

    Norzzug 
https://static.tvtropes.org/pmwiki/pub/images/norrzug.png

Debut: "Protector"

The ancient guardian of the city of Amon-Ra, Norzzug eventually became too dangerous and was forced into a river, rusting him solid for centuries. After being unintentionally revived by archaeologists, the giant lion statue began attacking nearby oil refineries to absorb the fuel housed with them. H.E.A.T. and Godzilla confronted Norzzug, though he was able to escape by creating a sandstorm to disable Godzilla. After consulting the archaeologists that revived him, H.E.A.T. learned of its vulnerability to surface oxidizing. They lured Norzzug to a salt mine with oil and sprayed him with a special chemical that would rapidly rust him when exposed to seawater. Godzilla returned and fought Norzzug, forcing him into the sea and rusting him solid again.


  • Blow You Away: Norzzug can create hurricane-force winds just by flapping his wings.
  • Elemental Baggage: Subverted; Norzzug can only breathe fire for so long before it has to replenish its oil reserves. It's dependency on fuel sources allows H.E.A.T. to lure it into a trap.
  • Fiery Lion: It's a fire-breathing lion statue.
  • Kill It with Water: After being sprayed with a special chemical, Norzzug is forced into the sea where the chemical reacts with the salt water to rust him solid.
  • Living Statue: Of a giant winged lion.
  • Panthera Awesome: Norzzug has the appearance of a giant winged lion.
  • Playing with Fire: So long as it's absorbed enough oil, Norzzug can breathe a constant stream of fire from its mouth.
  • Shout-Out: Norzzug bears a strong resemblance to the Griffon from the 1969 Toho Film Latitude Zero. Possibly also to King Caesar: both are living statues based on mythical lion-like creatures that served as protectors.

    Medusa 
https://static.tvtropes.org/pmwiki/pub/images/medusa_48.png

Debut: "Freak Show"

Medusa is a mutated sea anemone found on a Pacific atoll by mutant circus owner Tobias Wilson, who intended to put it on display at one of his shows. During a show in New York, Medusa escaped confinement by turning into a liquid form, going on a rampage and draining bystanders of water. It eventually reached New York's water reservoir, where Godzilla confronted it. After nearly killing Godzilla, Medusa made her way to the sea, but Godzilla was quickly revived by the military and repeatedly blasted it with atomic breath, melting Medusa and preventing it from reforming. H.E.A.T. sucked up the liquidated mutation with a huge vacuum meant to clean up oil spills.


  • Body Horror: After being drained by Medusa, her victims are left barely alive as shriveled-up husks.
  • Combat Tentacles: Mesusa uses its tentacles to grab victims and absorb the water from their bodies.
  • Cyclops: It only has one eye.
  • I'm Melting!: Medusa is able to turn to liquid and reform at will. It also melts when exposed to high temperatures, such as Godzilla's atomic breath.
  • Miracle-Gro Monster: It grows larger the more water its body absorbs.
  • Tentacled Terror: A mutated sea anemone that uses its tentacles to drain living things of their water.

    Ts-eh-Go 
https://static.tvtropes.org/pmwiki/pub/images/ts_eh_go.png

Debut: "Where is Thy Sting"

Ts-eh-Go is a prototype, genetically engineered scorpion bio-weapon created by the US military in the deserts of New Mexico. After Godzilla begins making a beeline for the arachnid's location, H.E.A.T. arrive in New Mexico and are confronted by the giant scorpion, though Godzilla forces it to retreat. Colonel Charles Tarrington, the man in charge of the project that created Ts-eh-Go, reveals that the mutation is too uncontrollable and shows H.E.A.T. a batch of smaller scorpions, dubbed "Second Wave". With Ts-eh-Go no longer necessary, the military turns on the scorpion. In the ensuing chaos, Godzilla is incapacitated by the scorpion's sting, while a downed helicopter accidentally frees Second Wave. H.E.A.T. manages to revive Godzilla and uses a pheremone sample to lure the smaller scorpions to attack their giant predecessor. Now overwhelmed, Ts-eh-Go was powerless to defend itself as Godzilla returned and wiped out all of the scorpions with his atomic breath.


  • Acid Attack: Able to shoot acid from its stinger as a ranged attack. It uses it to weaken Godzilla's skin enough to sting him after it fails to penetrate Godzilla's hide the first time.
  • Beware My Stinger Tail: It’s a Scorpion so this is a given.
  • Early-Bird Cameo: A smaller but otherwise identical mutant scorpion named Scorpio briefly appears in the earlier episode "Freak Show".
  • Expy: Of the Giant Scorpions from The Black Scorpion.
  • Flawed Prototype: Ts-eh-Go is created by the US military as a living weapon, but proved too hard to control. The "Second Wave" scorpions are meant to replace it, as their smaller size makes it easier to control, house, transport, and feed them than their giant predecessor.
  • Kill It with Fire: Both Ts-eh-Go and Second Wave are completely roasted by Godzilla's atomic breath.
  • Mini Mook: After Ts-eh-Go proves to be too uncontrollable, the army develops "Second Wave", an army of scorpions each about the size of a cat or small dog. Sure, they're still large enough to qualify as Big Creepy-Crawlies, but they're positively tiny compared to the building-sized mutations usually encountered by HEAT.
  • Scary Scorpions: Again, it's a giant scorpion.
  • Tunnel King: It's able to burrow underground as a secondary means of locomotion.
  • What Happened to the Mouse?: After the scorpions are destroyed and H.E.A.T. leaves, Colonel Tarrington authorizes the development of "Third Wave", though nothing ever comes of this.
  • Zerg Rush: The smaller "Second Wave" scorpions tend to swarm their prey, though this could be attributed to them all reacting to pheremone markers on the target rather than an intentional strategy.

    Giant Turtle 
https://static.tvtropes.org/pmwiki/pub/images/giant_turtle_2.png

Debut: "End of the Line"

The Giant Turtle made its first appearance off the coast of Alaska, attacking the cruise ship Borealis, where Nick and Audrey were having a romantic cruise on. When the two become stranded on a nearby deserted island, the Turtle attacks them again, but is driven off by Komodithrax when it draws too close to her nest. Later, the Turtle returns and is able to steal Komodithrax's egg while she is distracted by the military. Godzilla intervenes, but is defeated by the Giant Turtle. Komodithrax returns and pushes the Turtle into a fissure in the ice, but the turtle pulls her and her egg into the fissure with it.


  • Disney Villain Death: After being flipped onto its back, the Giant Turtle can only flail its legs helplessly as Komodithrax pushes it into a massive fissure in the Arctic ice.
  • Mutual Kill: Gets pushed into a fissure in the ice by Komodithrax, but manages to pulls her down with it.
  • Shout-Out: It bears some similarities to Kamoebas, namely its spiky carapace and extendable neck. He even dies dragging his opponent down with him, just like Kamoebas did to Ganimes in Space Amoeba.
  • Spikes of Villainy: It's shell is covered in spikes, fitting for the monster responsible for the death of Godzilla's mate.
  • Stock Dinosaurs: Partially resembles an ankylosaurus, with his spiky carapace and clubbed tail.
  • Super-Persistent Predator: He is relentless in getting Komodithrax's egg, even fighting off both her and her mate.
  • Tail Slap: Its primary attack, due to the large clubbed end. Just one swing is enough to leave Godzilla stunned for a brief time.
  • Taking You with Me: The Giant Turtle grabs onto Komodithrax leg as it falls, pulling her and her egg into the crevice with him.
  • Turtle Power: It's a snapping turtle kaiju capable of knocking Godzilla senseless with one swing of his clubbed tail.

    Komodithrax 
https://static.tvtropes.org/pmwiki/pub/images/komodithrax.png

Debut: "End of the Line"

Komodithrax is a mutated Komodo dragon that H.E.A.T. encountered in a deserted island off the coast of Alaska after it defeated the Giant Turtle that menaced Nick and Audrey. Shortly afterwards, Nick discovered that Godzilla and Komodithrax were mates and Godzilla was acting as a surrogate father to her unhatched egg. The US Military attacked the nest to destroy all the monsters present, and the Giant Turtle took advantage of the chaos to steal Komodithrax's egg. After Godzilla was knocked unconcious, Komodithrax arrived, flipping the turtle onto its back and pushing it into a fissure in the ice. However, the Giant Turtle clutched onto the edge of the crevice, causing it to collapse and send Komodithrax and her egg falling into the fissure after it.


  • Breath Weapon: She can fire a blue Atomic Breath from her mouth.
  • Dire Beast: She is a kaiju-sized komodo dragon, but aside from her size looks the same as a normal komodo dragon.
  • Informed Species: Nick states that Komodithrax is a member of the same species as Godzilla despite him being a mutant iguana and her a mutant komodo dragon — likely a relic for when she was a member of Godzilla's species early in development.
  • Monster Is a Mommy: She reproduced via parthenogenesis and laid an egg. Unfortunately, both she and the egg perish falling into a crevice.
  • Mutual Kill: She pushes the Giant Turtle into a fissure in the ice, who in turn pulls her down with it.
  • Temporary Love Interest: For Godzilla, who becomes her mate in the episode until she's killed by falling into a crevice.

    Bacillus 
https://static.tvtropes.org/pmwiki/pub/images/bacillus.png

Debut: "What a Long, Strange Trip It's Been"

Bacillus is a mutated bacterium that appeared on the outskirts of New York City, where it was confronted by H.E.A.T. and Godzilla. During the battle, it infects both Godzilla and Craven, but is seemingly killed by Godzilla's atomic breath. Later, while Godzilla is too sick to fight, Bacillus reappears, having formed an endospore barrier around itself to survive. It began heading straight for New York City's water supply, with Randy using the Heat-Seeker to keep it away long enough for Godzilla to revive. Even before Godzilla can resume the fight, the now-cured Craven drives a speed boat containing a barrel of the antidote directly towards the germ's gaping max, causing Bacillus to dissolve.


  • Combat Tentacles: Bacillus has several tentacles surrounding its mouth that it uses to bind opponents. It also has a bladed tentacle-like appendage it can extend from its mouth to directly infect other kaiju.
  • Instant Illness: Both Godzilla and Craven get sick within a matter of minutes of being exposed to Bacillus. After being treated, both recover just as quickly.
  • Luckily, My Shield Will Protect Me: Bacillus is able to form an endospore around its body as a shield to protect itself from extreme conditions. It's even strong enough to survive Godzilla's atomic breath.
  • Mini Mook: After Bacillus infects Godzilla, Nick and Monique discover dozens of beachball-sized bacilli in Godzilla's bloodstream and around his brain stem.
  • Non-Indicative Name: Real-world bacilli are rod-shaped bacteria ("Bacillus" being the Latin word for "stick"). By contrast, Bacillus is spherical, looking more like a generic germ than anything else.
  • Not Quite Dead: It's seemingly killed by Godzilla during their first encounter, only to return while Godzilla is out of commission.
  • Plaguemaster: It's a mutant bacteria capable of infecting both man and mutation. While Godzilla is out of action, it attempts to infect New York's water supply.
  • Shout-Out: The way Bacillus infects Godzilla with tiny versions of itself, putting him in a comatose state, is similar to how Jiger disabled Gamera by implanting her offspring into his body . In both cases, scientists pilot a minisub into the infected kaiju's body to kill the parasite from within.
    • An early draft of Godzilla vs. Mechagodzilla II had a team of scientists being injected into Godzilla's body to battle him from within, making this an inverse Shout-Out by instead having the scientists trying to save Godzilla instead.

    Sub-Zero Manta 
https://static.tvtropes.org/pmwiki/pub/images/sub_zero_manta_3.png

Debut: "Wedding Bells Blew"

A mutated manta ray that could fly and shoot ice beams from its mouth, the Sub-Zero Manta appeared in an aquarium in New Jersey, taking up residence in the penguin exhibit. It later moves on to a nearby frozen food packaging plant where H.E.A.T. found it. Nick eventually realizes that the Sub-Zero Manta is looking for some place cold and lure it to a nearby ice rink, where it begins hibernating. While waiting for the military to come transport the monster away, the arena's generator dies and the temperature rises, awakening the Sub-Zero Manta. Godzilla again confronts the Manta, with their fire and ice attacks creating a massive thunderstorm. The two combatants head out to sea, with Godzilla pulling the manta underwater. Godzilla begins swimming in circles, creating a powerful whirlpool that drags the Sub-Zero Manta down, never to be seen again.


  • Flying Seafood Special: A mutated manta ray capable of flight.
  • Giant Flyer: Big enough to cover most of an ice hockey rink.
  • An Ice Person: Fires a highly concentrated freezing attack.
  • Non-Indicative Name: It's Japanese name translates to "Bird of Prey", likely due to the creature originally being a bird mutation until it was changed to a manta ray
  • Shout-Out: Possibly a reference to a giant flying manta ray from The Godzilla Power Hour episode "The Macro-Beasts".
  • Tragic Ice Character: To an extent, the Manta can be seen as this: it originated in the Arctic and somehow lost its course, ending up in the New York area and began searching for a suitable habitat, only to be confronted by Godzilla and presumably killed for its troubles.

    Megapede/Cicada 
https://static.tvtropes.org/pmwiki/pub/images/megapede_form_1.png
Megapede
https://static.tvtropes.org/pmwiki/pub/images/megapede_form_2.png
Cicada

Debut: "Metamorphosis"

Megapede first appeared in the American Midwest, ravaging nearby farms. H.E.A.T. arrived to investigate and ran into the creature as it attacked the Indiana State Fair. Godzilla gains the upperhand, but the Megapede spits poison in Godzilla's eyes, forcing him to retreat to wash his eyes out. Without Godzilla, H.E.A.T. is helpless to stop Megapede from disappearing into the ground. After building an electrical net to trap the Megapede, they follow it down its hole, only to find an empty coccoon. The now-metamorphosed Cicada heads towards Chicago and begins producing a mating call, which disables electronic signals across the city. H.E.A.T. coats the creature's wings with insulating foam, stopping its call, and Godzilla arrives, chasing the giant insect into Lake Michigan and drowning it.


  • Big Creepy-Crawlies: A kaiju-sized centipede that metamorphosizes into a kaiju-sized cicada.
  • Creepy Centipedes: Naturally.
  • Expy: Of Battra, with Megapede as the larval form and Cicada as its adult form. Its two fights with Godzilla take place at a carnival and underwater, very similar to Battra's two brawls with Godzilla.
  • Kill It with Water: Godzilla drowns the Cicada in Lake Michigan.
  • Kryptonite Factor: Megapede has a vulnerability to electricity. H.E.A.T. builds an electrical net to trap it, only to learn that it had lost its weakness after metamorphosizing into Cicada.
  • Metamorphosis Monster: It changes from a giant mutant centipede into a giant mutant cicada.
  • Somewhere, an Entomologist Is Crying: Nick states that it is a hybrid of a centipede (a Myriapod) and a cicada (an insect), two species separated by hundreds of millions of years of evolution.
  • Spike Shooter: The Megapede is able to shoot poisonous barbs at his enemies.
  • Super Spit: In both of its forms, it has a poisonous spit attack that can blind its enemies.
  • Tunnel King: In its first form, it is able to burrow through the ground with ease.

    Giant Armadillo 
https://static.tvtropes.org/pmwiki/pub/images/giant_armadillo.png

Debut: "Area 51"

The Giant Armadillo was one of many mutations caused by nuclear testing at Areat 51 in the 1950's. It burrowed out of its enclosure and began running amok inside the walls of Area 51, encountering a pair of trespassers searching for signs of alien life. A photo the two men take appears on the news, attracting the attention of H.E.A.T., who offered their assistance in recapturing the mutation. Randy comes up with a plan to entangle the Armadillo in the root system of a giant Mesquite plant, which is successful. The Giant Armadillo was then transported back into its enclosure.


  • Disc-One Final Boss: The Giant Armadillo is quickly captured by H.E.A.T. with no assistance from Godzilla whatsoever. The Thorny Devil is then revealed to be the episode's real antagonist.
  • Tunnel King: A skilled burrower, which allowed it to escape its enclosure.
  • Unwitting Instigator of Doom: The Giant Armadillo's escape also allows the Thorny Devil to break out of its own enclosure and nearly escape Area 51 altogether.

    Thorny Devil 
https://static.tvtropes.org/pmwiki/pub/images/thorny_devil.png

Debut: "Area 51"

The Thorny Devil was one of many mutations caused by nuclear testing at Area 51 in the 1950's. After H.E.A.T. had helped the military recapture the Giant Armadillo, the base's overseer Dr. Candace Kirk revealed that the Thorny Devil had also escaped when the Giant Armadillo had gotten out of its enclosure. H.E.A.T. located the giant lizard, which proved too much for them, but Godzilla arrived to protect his friends. The Thorny Devil was able to overwhelm Godzilla with a barrage of venomous spikes and tried to break down the gates of Area 51. Godzilla recovered enough strength to resume the battle, flipping the Thorny Devil onto its back and slaying it with his atomic breath.


  • Achilles' Heel: While most of his body tough enough to tank Godzilla's Atomic Breath, his underbelly is much more vulnerable.
  • Bottomless Magazines: The spikes it shoots from the back of its neck are constantly regenerating, giving it a limitless supply of poisonous ammunition.
  • Family-Unfriendly Death: After being flipped on his back, the Thorny Devil is roasted alive by Godzilla's Atomic Breath, screaming in pain all the while.
  • Kill It with Fire: How it meets its demise.
  • Misplaced Wildlife: The thorny devil is a real species of lizard, yet they are native only to Australia, not Nevada.
  • Overly Long Tongue: It has a long spiked tongue that it can use to skewer prey with.
  • Poisonous Person: Each of the projectiles it shoots from its back are said to contain the toxic equivalent of 20 scorpion stings.
  • Reptiles Are Abhorrent: A giant mutated lizard and antagonist to Godzilla.
  • Spike Shooter: It can launch dozens of venomous spikes from the back of its neck.
  • Spikes of Villainy: As its name suggests, the Thorny Devil's head and back are covered in bony spikes.
  • Tunnel King: Not quite on par with Godzilla himself, but an exceptional burrower nonetheless.

    Silver Hydra 
https://static.tvtropes.org/pmwiki/pub/images/silver_hydra_2.png

Debut: "Shafted"

The Silver Hydra is a mineral-based kaiju of unknown origin that lived in a mine in Blind Rock, Wyoming. It first emerged in the 1940's, encasing a group of miners in silver, eventually leading to the mine being shut down and the town abandoned. In a nearby town in the modern day, H.E.A.T. hears the legend of the mine and decides to investigate and encounters one of the Hydra's, which sprays liquid silver on Elsie's leg, quickly encasing it as the silver spreads. Craven was able to slice up the hydra with a hand-held laser, though the individual pieces reform into smaller hydras. Godzilla arrives and melts the hydras with his atomic breath, but they regenerate into a single, two-headed Silver Hydra, which entraps Godzilla in liquid silver. H.E.A.T. decides to flood the mine with cold water from a nearby spring, reasoning heat from nearby Yellowstone Park's geysers had awoken it from hibernation. The cold water causes the Silver Hydra's body to solidify and shatter.


  • Asteroids Monster: The Hydra is able to split into smaller individuals, which can later remerge into a massive two-headed version.
  • Blob Monster: Though it has a distinctive head and limbs, most of its body is a shapeless mass of liquid silver.
  • Eyes Do Not Belong There: The Silver Hydra has multiple eyes on both sides of each of its antenna.
  • Kryptonite Factor: Cold temperatures cause the Silver Hydra's body to solidify and shatter.
  • Literally Shattered Lives: After cold water solidifies its body, the Silver Hydra shatters like glass.
  • Multiple Head Case: When the smaller hydras merge together, the Godzilla-sized Silver Hydra has two heads.
  • Shout-Out: Possibly to Destroyah; its ability to split into numerous smaller hydras and merge into a larger two-headed form is similar to Destroyah shifting between its Juvenile and Aggregate forms. Also, it ends up shattering after its body is subjected to cold temperatures.
  • Silicon-Based Life: As its name implies, the Silver Hydra's body is comprised of silver.
  • Trap Master: It shoots out liquid silver that spreads to cover a larger area than what was originally hit. This allows it to quickly immobilize its victims and eventually smother them as their bodies become entirely encased in silver.

    Lizard Slayers 
https://static.tvtropes.org/pmwiki/pub/images/lizard_slayers.png

Debut: "Lizard Season"

The Lizard Slayers are a trio of mechas built by Cameron Winter to kill Godzilla, with Winter breaking amateur monster hunters Dale, Hank, and Bill from prison to pilot them. The three mechas engaged Godzilla, quickly overwhelming him. H.E.A.T. calls in the military to assist Godzilla, though the Lizard Slayers are able to fight off the Army while Godzilla makes his escape. The members of H.E.A.T. are able to bring down Lizard Slayer 2 and Lizard Slayer 3, while Nick and Major Hicks infilitrate Lizard Slayer 1. After a brief fistfight, Godzilla bites through Lizard Slayer 1's armor, forcing its pilot to surrender. The pilots are placed under arrest, and Cameron Winter denies having any connection with them, claiming his mechs were stolen, allowing him to escape justice once again. Winter later calls Nick to gloat that the military was impressed with the machines and placed a large order for Lizard Slayers of their own.


  • BFG: Lizard Slayer 1 has a large cannon in each arm, and Lizard Slayer 3 has a single cannon above the cockpit.
  • The Bus Came Back: The three pilots had previously appeared in "Cat and Mouse", where they attempted to kill Godzilla and were arrested for the destruction they caused in the process.
  • Everyone Has Standards: While perfectly content to hunt down Godzilla, both Hank and Bill are apprehensive about going against the US military, and Bill outright refuses to attack the HEAT Seeker with people onboard.
  • Gatling Good: Lizard Slayer 1 has a minigun mounted on the front of the torso.
  • Humongous Mecha: Designed by Cameron Winter specifically to hunt down Godzilla and other mutations.
  • Imperial Stormtrooper Marksmanship Academy: The Lizard Slayers accidentally hit one another just as much as (if not more so than) Godzilla. They're so bad that they even shoot one another during target practice.
  • Land, Sea, Sky: The three mechs are each designed for different purposes: Lizard Slayer I is a terrestrial-based exosuit, LSII is an amphibious attack vessel, and LSIII is aerial assault vehicle.
  • Macross Missile Massacre: Each of the Lizard Slayers is loaded out with tons of missiles (Lizard Slayer II is explicitly stated to have enough firepower to take out the US Seventh Fleet).
  • Shock and Awe: Lizards Slayer I has short-range tasers built into its chest.
  • Shout-Out: The Lizard Slayers are possibly a reference to the Spider Slayers, a series of armored suits built to defeat Spider-Man.
  • Shout-Out Theme Naming: The three pilots are named Hank, Dale, and Bill.
  • Unskilled Yet Strong: The Lizard Slayers are indeed up to the task of taking on Godzilla. The pilots? Not so much.
  • Walking Armoury: Each Lizard Slayer has a wide assorment of missiles and guns, Lizard Slayer 1 has tasers for short-range combat, Lizard Slayer 2 packs torpedoes for underwater use, and Lizard Slayer 3's got laser weaponry.

    Giant Mutant Hummingbird 
https://static.tvtropes.org/pmwiki/pub/images/giant_mutant_hummingbird.png

Debut: "Vision"

The Giant Mutant Hummingbirds were mutated by flowers contaminated with chlorofluorocarbons (CFC) in California's redwood forests. These monsters made their way to San Francisco in search of new sources of CFC's, attacking a military jet. Because of their reflective feathers and high speed, the hummingbirds were impossible to see under normal circumstances, making it impossible for Godzilla to properly fight them. Craven and Randy created a pair of goggles that allowed Godzilla to see the Mutant Hummingbirds, who were then quickly defeated. The Pentagon then decided to study their stealth capabilities to create new stealth jets.


  • Acid Attack: The hummingbirds have an acidic spit that can quickly eat through the windshields of military aircraft.
  • Bizarre Taste in Food: The Hummingbirds are addicted to chlorofluorocarbons, attacking planes that use CFC's as fuel.
  • Curb-Stomp Battle: Once they lose the advantage of stealth, the Mutant Hummingbirds are easily defeated by Godzilla without offering up the slightest bit of resistance.
  • Fragile Speedster: They can keep pace with jet airliners, burt they can't take a hit to save their lives.
  • Made of Iron: Zig-zagged; the hummingbirds are some of the weakest mutations in the series, easily being curb-stomped by Godzilla, yet all of them manage to survive attacks that killed supposedly tougher mutations in other episodes.
  • One-Hit Point Wonder: Every last one of them gets one-shotted by Godzilla.
  • Super Speed: So fast that they're impossible to see with the naked eye, requiring H.E.A.T. to construct special goggles to allow Godzilla to see them.

    Armillaria 
https://static.tvtropes.org/pmwiki/pub/images/armillaria.png

Debut: "Underground Movement"

Armillaria is a giant, mutant fungus that attacked and destroyed farmland in Michigan. With its food supplies running low, it began attacking people, getting the attention of H.E.A.T. The fungus fended off Godzilla and nearly killed Monique, though H.E.A.T. eventually managed to locate its body. After the military dug up Armallaria, Godzilla threw it onto a nearby beach, cutting it off from any sources of food, and then incinerated it with his atomic breath.


  • Aliens in Cardiff: Rural Michigan is not the first place you would expect a giant mutated mushroom to start wreaking havoc.
  • Combat Tentacles: The Armillaria has dozens (if not hundreds) of tentacles that it uses to siphon off amino acids from its victims. The tentacles can extend for miles from the Armillaria's body and are strong enough to bind Godzilla.
  • Evil Is Bigger: While its body is hardly bigger than Godzilla's head, its tentacles eventually extend across an area of more than 1500 acres (2.34 square miles or 6 square kilometers), surpassing every other mutation in sheer size.
  • Fungus Humongous: A mushroom mutated to kaiju-sized proportions by pesticides.
  • Parasites Are Evil: Armillaria are parasitic mushrooms, and this one is so large that not only has it reduced miles of farmland into a wasteland, it's also started going after people to drain their amino acids.
  • Shout-Out:
    • It could be a nod to Biollante, as it is based on a lifeform other than an animal (in this case, a fungus) and attacks Godzilla with tentacles.
    • The Armillaria's tentacles bursting from the ground and grabbing the nearest object is possibly a reference to the Graboids from the Tremors series.
    • It is also possibly a reference to the mutated fungus from the Toho film Matango. The Armillaria's ability to siphon nutrients from its victims is similar to how Matango drains energy from its victims in its appearance on Godzilla Island

    Fire Monster 
https://static.tvtropes.org/pmwiki/pub/images/fire_monster.png

Debut: "Ring of Fire"

The Fire Monser first appeared on an oil rig in the Gulf of Mexico, feeding off the oil as a fuel source. H.E.A.T. investigates the damaged rig and tries unsuccessfully to combat the Fire Monster. Godzilla arrives to fight it, but Godzilla's atomic breath only strengthens the Fire Monster. After discovering the Fire Monster is feeding off the oil to fuel its fire, H.E.A.T. leads it out into open ocean, where its fuel eventually runs out. Craven wanted to study the creature and, against Nick's wishes, secretly transports the Fire Monster back to H.E.A.T. headquarters. However, the Fire Monster revives when the creature's methane blood causes an explosion after contatcting a furnace's pilot light. Craven and Randy then rig N.I.G.E.L. with nitroglycerin and send him at the creature, with the explosion displacing the oxygen and defeating the Fire Monster. H.E.A.T. then seals it in a capsule and drops it into the sea.


  • Alien Blood: It bleeds methane.
  • Big Creepy-Crawlies: It’s an earwig the size of a horse.
  • Feed It with Fire: Godzilla's atomic breath just makes the Fire Monster's flames more powerful.
  • Not Quite Dead: After defeating it the first time, Craven sneaks it back to New York so that he can study it, but as soon as it gets a spark it springs back to life. They don’t take any chances the second time, placing it in an air-tight capsule and dropping it in the ocean.
  • Playing with Fire: What else would you expect from a creature called the Fire Monster?
  • The End... Or Is It?: as soon as the capsule hits the ocean floor it’s smashed open by a wayward shark.
  • Wreathed in Flames: The Fire Monster is able to surround itself with a fiery aura several times its own size.

    Swamp Beast 
https://static.tvtropes.org/pmwiki/pub/images/swamp_beast.png

Debut: "The Ballad of Gens du Marais"

A creature of possible supernatural origin, the Swamp Beast appeared to attack a pair of oil hunters who entered its swamp. Later, while H.E.A.T. is investigating, the Swamp Beast attacks a catfish plantation owned by a local businessman named Dimanche. A local fisherman named George tells Nick that the Swamp Beast is the Spirit of the Swamp and that he can influence its actions, but not control it completely, and that Dimanche is trying to take the swamp away from the Gens du Marais (People of the Swamp). Later, the Swamp Beast attacks Dimanche's riverboat, but H.E.A.T. calls in Godzilla to hold it off while Nick points out to George that the Swamp Beast is endangering innocent bystanders. The Swamp Beast follows Dimanche back to his mansion, but George is finally able to call it off when Dimanche is arrested for his corrupt business practices.


  • Always a Bigger Fish: It makes its first appearance by dragging an alligator underwater after it had attacked two men in their boat.
  • Amphibian Assault: While not explicitly stated to be an amphibian (or an animal at all), it has the crouched posture of a toad. George uses it to attack businesses that are harming the swamp.
  • Dishing Out Dirt: The Swamp Beast is able to shoot out streams of mud from pores on its back.
  • Maybe Magic, Maybe Mundane: Is the Swamp Beast the swamp's guardian spirit as George and the other Gens du Marais believe, or is it a mutation caused by polluted groundwater as Nick maintains?
  • Mysterious Mist: The Swamp Beast's sudden appearances and disappearances are accompanied by thick fog that appears out of nowhere and fades just as quickly.
  • Pet the Dog: After George calls off the Swamp Beast, Nick stops Godzilla from pursuing it as it peacefully returns to its swamp.
  • Planimal: Its body is composed of both plant and animal matter.
  • The Power of Hate: George summons the Swamp Beast as a means of revenge when a local businessman continuously threatens the swamp and its inhabitants. He eventually lets go of his anger and calls off the Swamp Beast when Nick points out that his revenge is endangering the lives of innocent bystanders.
  • Supernatural Is Green: It's a giant green plant monster that may or may not be a supernatural entity.

    Deep Dweller 
https://static.tvtropes.org/pmwiki/pub/images/deep_dweller.png

Debut: "Tourist Trap"

A giant deep-sea-dwelling fish, the Deep Dweller was fored to the surface, where it became disoriented by the light and began attacking passing ships. It soon attacks the attention of H.E.A.T., who eventually try to lure it out of the Hudson Canyon and off the continental shelf.


  • Berserk Button: Due to it being accustomed to the depths of the ocean, bright lights cause the Deep Dweller to behave erratically and lash out at any light source that gets too close.
  • Fiendish Fish: A giant anglerfish with a mouth 40 feet across, capable of biting through the hulls of smaller ships.
  • Hellish Pupils: Its eyes have rectangular pupils like a goat.
  • Non-Malicious Monster: The Deep Dweller is just an extraordinarily large sea creature that ended up becoming removed from its native habitat and began lashing out in its confusion. Rather than destroy it, H.E.A.T. spends most of the episode trying to guide the creature back to deep water.
  • Sea Monster: It greatly resembles an anglerfish that is large enough to take bites out of small ships.
  • Vertebrate with Extra Limbs: In addition to a normal set of fins, it has a pair of three-toed forelimbs.

Others

    Major Anthony Hicks 
Voiced By: Kevin Dunn

  • An Arm and a Leg: In the Bad Future, he has a cyborg arm.
  • Godzilla Threshold: In Future Shock, Hicks reveals he freed every one of the mutations on Monster Island to try and fight the Dragmas. It didn't even slow them down.
  • Hero Antagonist: As a soldier, his job is to protect the American people from all threats, up to and including giant mutations. This puts him at odds with H.E.A.T. until Godzilla proves he is not a threat.
  • Majorly Awesome: To an extent. While he usually plays second fiddle to H.E.A.T. and Junior, Hicks does have his own moments of Awesome, is usually out on the field getting dirty, and does note that he sometimes have to follow orders despite the team's advice.
  • Old Soldier: In "Future Shock", he's still an integral part of the human resistance, despite being at least in his sixties and missing an arm. Of course, given humanity is on the brink of extinction, he doesn't exactly have much of a choice in the matter.
  • Reasonable Authority Figure: While he has voiced that he would prefer to nuke every mutation out there, he understands the necessity of keeping Junior around and has many times let HEAT do things their way to save the day.
    • At the same time, even when he goes against the team it's for reasonable reasons, often citing the chain of command or the threats to loss of life that could ensue.

    Audrey Timmonds 
Voiced By: Paget Brewster

  • Adaptation Personality Change: In the movie, Audrey was fairly timid, as opposed to her brash and assertive personality in the show.
  • Bad Future: According to Mendel, in the Dragma-overrun future, Audrey and her husband (presumably some man she married after Nick disappeared) were last seen planning to travel to New Zealand (apparently there are fewer Dragmas in the southern hemisphere...assuming you survive the ocean crossing).
  • Clingy Jealous Girl: She expresses jealousy towards Nick's relationship with Elsie.
  • The Determinator: She'll go through great lengths to get what she wants. This gets Deconstructed when her determination nearly caused S.C.A.L.E to break free all the mutations on Monster Island. Thankfully, Audrey learns from this and promises to not let her goals blind her to the potential consequences.
  • Going for the Big Scoop: This actually jeopardizes her relationship with Nick in one episode when Junior was going through his version of growing pains.
  • Intrepid Reporter: While she does cover normal stuff, she does like a bigger story. This gets Deconstructed as her desire to get the scoop has left negative impacts towards her life once or twice, especially with her relationship with Nick.
    • She lies in the news about Godzilla's threat level, even though her boyfriend tells her not to do it. This severely strains their relationship and while they do make amends, Nick isn't ready to forgive Audrey yet.
    • Her obssession to see Monster Island makes her the perfect Unwitting Pawn to an Eco-Terrorist and nearly brought about the end of the world.
  • Off the Record: During the episode where it was done documentary-style and dealing with "eco-friendly terrorists," Audrey destroyed the final tape, citing that some secrets are best kept hidden.
  • Red Shirt Reporter: As to be expected of an Intrepid Reporter in a world where giant monsters are the biggest news story there is.

    Victor "Animal" Palotti 
Voiced By: Joe Pantoliano

  • Deadpan Snarker: Much like in the movie, Animal frequently snarks at events.
  • Disappeared Dad: He went missing some time in the Bad Future, leaving behind his young son.
  • Nerves of Steel: While most other people are either ducking or scrambling for cover during the latest "Godzilla vs Monster of the Week" throw down, he still keeps on taping in the middle of the action and doesn't let go of his camera, come hell or high water.
  • Red Shirt Reporter: Being Audrey's main cameraman, it happens.

    Phillipe Rouche 
Voiced By: Keith Szarabajka

  • BFG: Carries a missile launcher with a special weapon that causes even a giant monster to be turned to stone-like substance before crumbling to dust.
  • Demoted to Extra: Despite his prominent role in the film, Phillipe's role is greatly reduced in the series, with only three total appearances (one being a voiceless cameo in the opening scene of the first episode and another being to tip off Monique to the DNA Mimic's existence).
  • Hero Antagonist: He spends an entire episode trying to kill Godzilla Jr., despite Randy and Monique's protests. At the last moment, he changes his mind and kills the Chameleon.

    Cameron Winter 
Voiced By: David Newsom

  • Arch-Enemy: To Nick.
  • The Bad Guy Wins: He got away with giving Humongous Mecha to three villains by claiming they stole the mecha from him and even convinced the government to buy mecha from him, which was his goal all the time.
  • Big Bad: The closest one in the series.
  • Corrupt Corporate Executive: Uses his business in less-than-legal ways.
  • Cut Lex Luthor a Check: Like the villain after whom the trope is named, he isn't above causing major disasters to be able to sell a way to solve it.
  • Deadpan Snarker: He's a jerk out to make money, but he's got quite the sense of humor.
    Winter: (Watching his Lizard Slayers doing more damage to one another than to Godzilla) It's official: I've hired The Three Stooges.
  • Expy: Of Lex Luthor. Corrupt Corporate Executive with a genius intellect? Check. Attempts to control and/or kill the most powerful creature on the planet? Check. Seemingly limitless resources? Check. Comically short prison sentences when he doesn't avoid prison altogether? Check.
  • Faux Affably Evil: Puts on a facade of manners, but undearneath is a greedy man who is only out for money.
  • Fiction 500: Downplayed; Cameron Winter is the wealthiest man in the world and can afford to create his own anti-Godzilla weaponry, but it's all done fairly realistically.
  • Four Eyes, Zero Soul: He wears glasses and is one of the more sinister antagonists in the series.
  • Greed: He's already stated to be the richest CEO in the world, but that isn't enough for him. He will enact more evil schemes to make more money, with no regard for who gets hurt.
  • Karma Houdini: Despite mind controlling Godzilla into attacking any army base, he got out of prison after a short sentence and his subsequent appearances he gets away with everything he does.
  • The Nicknamer: Constantly refers to Nick as "Nickels", an insult at Nick's financial prospects from their time in college.
  • Omnidisciplinary Scientist: Much like the heroes, it is never specified what Cameron's doctorate is in. His specialties appear to be robotics (hence his creation of the Cyber Flies and Lizard Slayers) and genetics (as he created the Chameleon, a clone of Godzilla).
  • The Sociopath: Has no problems with killing anybody or anything that gets in his way, his first appearance had him mind control Godzilla into attacking a military base so he could get a contract for the destroyed weaponry, showing no regard the number of people killed, and in "Trust No On", he created the Chameleon and had it attack New York while disguised as Godzilla just to make himself look like a hero when the Mimic killed the real thing.
  • Smug Snake: Very,very much so.
  • Villain with Good Publicity: While the heroes know better, to the rest of the world, Winter's just a successful businessman, allowing him to repeatedly avoid jail and profit off his criminal activities.

    Alexandra Springer 


  • Animal Wrongs Group: She turns S.C.A.L.E. from a peaceful group into a terrorist organization.
  • The Determinator: A darker and destructive example. She's so willing to accomplish her goals that she doesn't care about the consequences (if anything, she embraces them).
  • Eco-Terrorist: She wants Mutations to be the dominant force on Earth even if it means sacrificing humanity to do it.
  • From Nobody to Nightmare: S.C.A.L.E was once a peaceful animal rights group until Springer came along and turns it into a group of terrorists.
  • Humans Are the Real Monsters: She is most certainly of this mindset, believing that the new mutations should be the rightful rulers of the planet. Considering the mutations are the direct result of humanity's mistakes, she does have a point, though her methods are far too extreme.
  • Large Ham: Her ferocity is matched by her long-winded rants.
  • Manipulative Bitch: Springer spends much of her runtime playing Audrey like a fool, much to the latter's dismay.
  • Shadow Archetype: To Audrey, if her obsession for success goes out of control.
  • Taking You with Me: After her plan fails, she tries to activate Monster Island's self-destruct mechanism, though a soldier is able to stop her before she reaches the switch.

    Leviathan Aliens 
https://static.tvtropes.org/pmwiki/pub/images/leviathan_alien.png
Voiced By: Ron Perlman

The Leviathan Aliens first appeared in a spaceship stuck at the bottom of the ocean. Later, they take control of two of the scientists who explored their ship, using their telepathy to turn the members of H.E.A.T. against one another. They then took control of most of Earth's known mutations, sending them to attack major cities across the planet to soften them up for their invasion.


  • Alien Invasion: They orchestrate one during the "Monster Wars" storyline.
  • Aliens Are Bastards: They are aliens who want to invade Earth and subjugate humanity.
  • Arc Villain: They were the main threat in "Monster Wars" trilogy.
  • The Assimilator: After downloading information about Earth from Soppler and Hoffman, the Leviathan's plan to colonize Earth. During "Monster Wars", Soppler and Hoffman begin mutating into Leviathans as the trilogy progresses, only partially regressing back to human after the invasion is foiled.
