History Sandbox / MonsterverseHollowEarth

!!!'''Appears In:''' ''[[VideoGame/CallOfDutyModernWarfare2019 Call of Duty: Warzone]]'' (cameo in a cave painting) | ''Film/GodzillaXKongTheNewEmpire''

* AmbiguouslyEvil: While it's obvious from moment one that she's being ForcedIntoEvil by the Skar King, her own morality (and sanity) are a more open question for most of the film. [[spoiler:Happily for all involved, she proves to be a peaceful and friendly GentleGiant after Kong and Suko free her and help her get her revenge on her tormentor.]]

* AnimalJingoism: In the ''Godzilla x Kong: The Hunted'' comic, Kong finds, in a cave, depictions of different rivalries between different species of titans. Among these cave paintings is a a depiction of a conflict between what appears to be Shimo and Gozilla, implying Shimo may belong to a rival species to Godzilla much like the [=MUTO=]s and Kong's species.
* BeenThereShapedHistory: It's mentioned offhandedly that she was responsible for the last ice age. In the climax, she threatens to cause another ice age once she and Skar King make it to the surface.
* BeingEvilSucks: Clearly doesn't enjoy causing destruction and chaos being a NonMaliciousMonster, only doing it due to Skar King forcing her with a crystal to make her subservient to him.

* BlueMeansCold: Her skin and the spikes on her back are tinged blue, and she can shoot a blast of freezing breath.
* BreathWeapon: She can spit a freezing beam referred to the toyline as her Frost Bite Blast or Frost Bite Breath.
* CoDragons: She shares the role of Skar King's top enforcer with one of the Skar King's direct followers. She's his strongest minion, but she isn't genuinely loyal ''at all'' and only does his bidding when forced to do so.

** More Contrasting ''Reboot'' Antagonist but Shimo shares multiple similarities with that of Titanosaurus from ''Film/TerrorOfMechaGodzilla'' - to wit: both are subterreanean reptilian kaiju who serve as muscle for the main villain, both debuted in films that followed instalments that featured Mecha-Godzilla as the antagonist and both are revealed to be [[spoiler: ForcedIntoEvil via mind-control rather than actually malicious.]] The big difference between the two is that while Titanosaurus [[spoiler: died ([[UncertainDoom maybe]]) after being freed from the mind control Shimo gets a new lease on life and joins Kong as his steed and knight.]]

* CrystallineCreature: The second trailer shows Shimo's back being covered in blue and purple crystals from head to tail.
* DarkActionGirl: She's implied to be the most powerful female Kaiju seen yet, and is Skar King's [[TheDragon pet]].

* DragonInChief: Shimo is actually much stronger than Skar King is, and her presence makes him a significantly bigger threat. [[spoiler:Skar King getting his control crystal destroyed is effectively the heroes' win condition.]]
* TheDreaded: The mere sight of Shimo's eyes emerging from the pit is enough to cause Suko to display a genuine OhCrap expression on his face as he starts to worry for Kong's safety.

** To Godzilla, in much the same way that Skar King is a simian titan like Kong, Shimo is an ancient reptilian titan with her own BreathWeapon [[spoiler: however she is not truly evil, rather she was being ForcedIntoEvil against her will by the Skar King.]]

* GlowingEyesOfDoom: A scene from the second trailer shows Shimo completely obscured by a dark pit, with only her eyes glowing in its darkness. In the same scene, Kong finds himself dreading at the possibility of having to face her.
* HeelFaceTurn: [[spoiler:Near the end after the crystal that Skar King was controlling her with is destroyed, she turns against her abusive former master and freezes him allowing Kong to pound him to smithereens.]]
* HeroOfAnotherStory: The novelization reveals that she was the one who froze Ghidorah in ice, thus ensuring they would remain trapped and unable to continue in their apocalyptic plans.

* KnightInShiningArmor: What she becomes after [[spoiler: being freed from Skar King's control. In a lot of ways, she fits the classical depiction of a knight: she's a powerful warrior who has sworn herself in service to [[TheGoodKing a benevolent ruler]], she has shiny white scales evocative of a knight's armour and Kong even rides her like a horse, bringing to mind the image of a knight's noble white steed.]]

* MirrorCharacter: Despite their contrasts, Shimo and Rodan have similar roles in the story. Shimo is also a reptilian Titan serving as TheDragon to a villainous Alpha Titan and is set up to be the EvilCounterpart to the BlueIsHeroic {{Deuteragonist}} titan; Godzilla in her case.

* PinkGirlBlueBoy: Gender inverted with Shimo, whose colors are white and blue for being a Titan with ice-based powers, while Godzilla has gotten a metamorphosis in ''The New Empire'' that gives him pink highlights.

* PowerGlows: When Shimo prepares to attack, she emits a powerful blue glow.

* SuperToughness: Enough to tank a supercharged Godzilla's atomic breath.
* TailSlap: In one of the sneak-peeks, Shimo slams Kong into a building with her huge tail.
* TimeAbyss: While her exact age is unknown, the fact that she's been referred to in some sources as "The First Titan", indicating her to be older than any other Titan, puts her here by default. For reference, it's stated in the film that she was partly responsible for the Ice Age, and the novelization indicates her to be at least 3 million years old.
* ThroatLight: Shimo's throat and eyes emit blue light when she is charging her freezing beam.
* UnblockableAttack: Her frostbite beam is so powerful that Kong's axe cannot withstand the attack like it does with Godzilla's atomic breath. She almost freezes both the axe and Kong in the trailer.
* WorldsStrongestMan: A ''serious'' contender for this amongst the Titans. Sources say that she caused the first Ice Age through her powers, and even when not actively using them, merely being in the area causes the surrounding environment around her to freeze, a state of being that Godzilla has to actively force himself into through absorbing massive amounts of energy. Skar King's control over her makes his rule undisputed amongst any Titan that opposes him, and whenever his own combat showing isn't enough to bring down his enemies, he falls back on using Shimo's brute force to overwhelm them. Kong is able to handle him well enough Solo, but a single blocked attack from Shimo's BreathWeapon leaves him with crippling injuries that require the B.E.A.S.T augmentation in order for Kong to use his arm again. Godzilla spends much of his time on the surface absorbing and refining ''massive'' amounts of energy to achieve a NextTierPowerUp to stand against Shimo, and even with that, it merely allows him to endure being frozen and match her physically, spending much of the clash between them holding Shimo back from unleashing too much destruction at Skar King's bidding rather than decisively overpowering her. Admittedly, Shimo herself does Godzilla no major damage either. [[spoiler:Thankfully, this immense power is counterbalanced by Shimo being a NonMaliciousMonster who has no interest in actively using her strength to assert dominance]].

!!!'''Great Apes'''

A sadistic, tyrannical and brutal dictator who rules over a tribe of Great Apes with an iron fist and is personally responsible for the deaths of countless other Titans, including his own kind. The warmonger uses Shimo, '''the Mother Of All Titans''' as a personal attack dog to aid him in securing his reign. Obsessed with ruling over the Surface World, he led a war against Godzilla thousands of years ago that resulted in him and the remnants of his army being sealed away in a desolate region beneath even the normal Hollow Earth. Ever since then he has dreamed of escaping the prison realm and using the Ancient Titan to kill the Great Ruler and take his kingdom for himself.

* AbusiveParents: While never outright stated, the Skar King is heavily {{implied|Trope}} to be the Suko's father (which would also make him Suko's ArchnemesisDad), and a number of other orange-haired simian babies, as later on in the film, [[spoiler:there's a brief shot near his throne which shows a bunch of female Great Apes holding babies, all of them with the same orange colored fur as Suko]]. Not only was Suko evidently unspared the Skar King's brutality and cruelty based on his visible scars and initial viciousness towards Kong; but during the movie, the Skar King moves to [[WouldHurtAChild attack Suko]] ''purely'' for not joining the rest of his gang in laughing loudly enough at Kong's prosthetic tooth, [[spoiler:and when Suko's beloved caretaker pleads with the Skar King to be merciful, the Skar King responds by feigning mercy for a moment, then sending Suko's caretaker to their brutal death by lava immolation ''in front of Suko''. Finally, when Suko destroys the Skar King's Shimo-controlling crystal, the Skar King {{neck lift}}s Suko and tries to strangle him to death]].

* ArchEnemy: He's easily Kong's most hated and personal foe besides the long-deceased Skull Devil, with his sheer cruelty and goals far more malevolent than any foe Kong has faced in the past; the two hate each other from the minute they meet and Skar King's depravity only cements Kong's desire to stop him and his plans to conquer the world. It's more deliberate than even in-universe as according to director Adam Wingard, he envisioned the Skar King as Kong's arch nemesis in the same vein as King Ghidorah to Godzilla.
* AxCrazy: The Skar King is a warmongering, [[TheSociopath sociopathic]] monster of an Great Ape that murders his subordinates over petty slights and reacts with murderous rage at the first sign of ''any'' defiance, showing a [[{{Sadist}} taste for violent sadism]] that only the Kraken and Ghidorah have matched. [[spoiler:When the final battle with Godzilla and Kong spills over into Rio De Janeiro, he spends a fair chunk of his efforts wreaking havoc and terrorising the human populace ForTheEvulz.]]

* BadBoss: Skar's reign is mostly built on terror, with a small cadre of loyal enforcers abusing the great majority of the apes in his empire while the rest toil away working the stone of their territory towards his ends, with dissenters even being decapitated to have their heads mounted on stakes while he himself wields the trump card of Shimo; whom he controls through torturing her with the control crystal at the end of his whip. [[spoiler:Notably, after the tyrant is no more and Kong usurps him, his former subjects cheer for Kong, who had stood up for the abused slave laborers in his first introduction to them, when he arrives to take his rightful place as King of the Great Apes while Shimo clearly chooses to follow Kong of her own will, responding positively to his petting of her like a trusted horse.]]

* BerserkButton: While it doesn't take much to anger him, [[spoiler: he does get downright irate with Suko for not laughing loudly enough with the other apes at Kong's metal incisor.]] Insecure much?
* BigBad: Of ''Film/GodzillaXKongTheNewEmpire''. Not only is he oppressing Kong's species, but he plans to invade the Surface World after growing bored with his dominion over Hollow Earth.
* BiggerStick: Shimo is his. The King himself is a fairly powerful Titan and a talented, experienced fighter, but not really a huge deal in the grand scheme of things. It's having a Godzilla-tier monster as his enslaved attack dog that makes him a threat to the entire planet, and [[spoiler:once his mind control of her is gone, [[NoHoldsBarredBeatdown it's all over bar the smashing.]]]]

* BloodKnight: The Skar King is constantly looking to indulge his lust for violence, whether it be through acts of petty cruelty or outright wars of aggression. This bit him back hard in the past, as the entire reason why Skar King was banished into the depths of the Hollow Earth in the first place was because he tried to pick a fight with the surface world, [[BeCarefulWhatYouWishFor and got one in the form of Godzilla.]] Unfortunately he didn't learn from the experience [[spoiler: and by the time he's freed from his prison come ''The New Empire'', is eager to try again with Shimo as his backup.]]
* BreedingSlave: Heavily implied to have a harem of them. Having enslaved the other great apes, Skar is seen on his throne with an entire line of abused, terrified female slaves all carrying offspring with orange colored fur like his own. Doesn't take a rocket scientist to put two and two together there.

* TheCaligula: ''Without a doubt''. The Skar King is what happens when a [[ControlFreak controlling]], [[AxCrazy murderously unstable and sadistically violent]] [[TheSociopath sociopath]] is put into a position of power that he should be ''nowhere'' near; an insane despot who uses torture and murder to coerce his terrified subjects into doing their bidding.

* ChokeHolds: [[spoiler: For using a long skeletal WhipOfDominance, that won't stop him for attempting to strangle his victims as he did while battling Kong by wrapping his weapon around his throat by garroting him as the latter is visibly gasping for air. Kong breaks free from his grasp and manages to overpower him.]] [[spoiler: After Godzilla destroys his whip, the attached crystal falls to the ground as Kong tried to grab it, only for Skar King to have his forearm locked around his neck to have him aggressively held back to seize control again over Shimo.]]

** Mechagodzilla in ''Film/GodzillaVsKong'' was a newly-made HumongousMecha and an EvilCounterpart for Godzilla, whereas Skar King is an organic AncientEvil Titan and an EvilCounterpart for King Kong.
** He also contrasts [[EvilInc Apex Cybernetics]], the human antagonists of ''Godzilla vs. Kong'' whose actions set off that movie's plot. Both are hegemonic schemers that stand apart comparative to most Titans for their uses of technology and higher intelligence to get what they want, and both seek to control a Titan of mass destruction that they're keeping inside their respective lairs as their attack-dog against Godzilla, Kong and any other threat so they can secure supremacy over the Earth for themselves. But whereas Apex were an up-and-coming mega-corporation, created their own [[HumongousMecha hi-tech cybernetic Titan]], and they were completely undone by [[SelfDisposingVillain their own hubris]] before they ever came close to realizing their dreams of conquering the Titans and ruling supreme on the Earth; the Skar King is an AncientEvil Titan who has already made significant progress toward establishing himself as the apex monster, having killed and enslaved other Titans including enough Great Apes to form an entire kingdom already, and he's using an ancient, organic Titan as his weapon while having much more success at controlling it than Apex had with their Titan weapon. Whereas Apex were a direct EvilCounterpart to fellow Titan-researching organization Monarch, the Skar King is a direct evil counterpart to fellow Alpha Titan simian Kong.
* ControlFreak: Wingard noted in an interview that a desire for control is one of Skar King's direct motivations. This shows in the movie itself, as part of his introduction see him threaten to assault Suko for the crime of not laughing at Kong hard enough for his liking, then murdering Suko's caretaker for trying to talk him down.
* TheConqueror: Skar had taken over many tribes of the Great Apes to try and make war upon the surface world and its ruling protector Godzilla. Ever since he was sealed in the badlands of the Hollow Earth, the False King longs for a rematch with the Great Ruler of the Titans and another attempt at conquering the surface with his army. Indeed, the Iwi describe him as being outright obsessed with it, and there is clear sadistic glee on his face when he finally reaches the surface again.

* DirtyCoward: Despite being a savagely formidable warrior, he ultimately displayed cowardice whenever faced with a superior opponent; which is why he would often rely on Shimo to carry out eliminating his targets.

* TheDreaded: He undoubtedly lords himself over the other Great Apes. Right when he drops down to face Kong, the rest of them are seen being either cautious or cowering as a few of them are slightly backing away from him. The Iwi consider him a massive threat and Godzilla almost died at his army's hand in the past despite ultimately coming out on top, when he begins to break free from his prison the King of the Monsters sees him as a big enough threat to begin powering up in preparation.

* EvilLaugh: Tends to react this way when things appear to be going in his favor. Being a SmugSnake, it's usually premature and the setup for a humiliating defeat.

* GreaterScopeVillain: Skar King is one for ''Godzilla vs Kong'', due to it being that he was the one who originally started the ancient war between the Great Apes and Godzilla, all because Skar wanted to rule the Earth all by himself.

* HumansAreTheRealMonsters: As an Ape Titan like Kong, Skar King is more human-like in his intelligence and mindset as opposed to the other Titans. However, unlike Kong who embodies the best parts of humanity and is a benevolent king, Skar King only embodies the worst traits of humanity and is a power hungry tyrant who seeks total submission over others.

* TheNapoleon: Skar King is noticably leaner than the other apes and slightly shorter than Kong. He also relies on intimidation and general nastiness to assert his authority while Kong earns loyalty by showing benevolence to his fellow ape. And as the climax demonstrates, [[spoiler: he's completey outclassed once he loses his weapon]].

* PunnyName: FunWithHomophones example; his title of "Skar King" can sound a lot like "scarring", and if there's one thing he appears to enjoy, it's going into battle with intent to hurt. In fact, the bloody handprints he leaves on his territory and on his cowed Kongs can make one think of him marking - ''scarring'' - them to demonstrate ownership.

* SatanicArchetype: A distinctly [[RedIsViolent red]]-themed, anthropomorphic-shaped tyrant who rules over an army of once-great protectors like himself that he reduced to lackeys in his own image (much like Satan seducing angels to his side in Heaven), and who seeks to usurp God (Godzilla), for which said God and his Angel (Mothra) locked the Skar King and his army away in a [[FireAndBrimstoneHell fiery, magmatic realm beneath the Earth]] long ago. The Skar King is prophesized to escape from his [[SealedEvilInACan prison]] and wage one last war against Godzilla and Mothra for total dominion over the world, attacking and jeopardizing mankind's world in the process, aided by a dragon that can bring about a cataclysm like in the Book of Revelations. This prophecy comes true in the present day, before the battle ends with the Skar King's final defeat and destruction at the hands of good. Adam Wingard has even described Skar King as a "devilish, Kong-type character".

!!!'''Appear In:''' ''Film/GodzillaXKongTheNewEmpire''
!!!'''Species:''' Giant Prehistoric Apes

Kong's people. A tribe of Great Apes who once ruled the Hollow Earth and have since been reduced to Skar King's slaves.
----
* CoDragons: While Shimo is Skar King's strongest minion, one ape with a distinct, very chimp-like design serves as Skar's right hand man. He is shown repeatedly reporting back to him and being shown to lead his forces when the False King himself is not directing things personally, as well as being more intelligent than the others. [[spoiler:He also serves as Suko's final opponent of the film.]]
* FacelessGoons: A bemasked ape forms part of Skar King's inner circle.
* ForcedIntoEvil: Many of the Great Apes don't ''want'' to invade the surface world as their instinct to protect humanity still remain but their fear of Skar King is so great to the point that it overcame it. However, the Skar King's inner circle are shown to be every bit as malevolent as their king.
* KillerGorilla: {{Downplayed}}. They're a whole species of powerful 250-foot-tall gorilla-like people, though most of them are actually only evil due to being forced to by Skar King. Skar King's inner circle on the other hand, plays the trope completely straight being as evil as their king without a hint of hesitation towards the cruelty they engage in.
* PsychoForHire: The Skar King's direct followers are just as sadistic and cruel as he is, and like him, they relish their power over their 'inferiors.'
* SlaveMooks: All of the Great Apes bear Skar King's brand and under his rule they have two options: serve or die. It's downplayed with his direct followers who are shown to have the same level of sadism and willingly follow him.
* UngratefulBastard: Kong almost knocks one of the apes attacking him off a cliff, but catches him at the last second and helps him up. However, the ape ignores Kong's altruism and tries to kill him anyway. For his troubles, Kong throws him off the cliff for real.
[[/folder]]

A simian juvenile creature with a general appearance similar to Kong.

* CharacterDevelopment: Seeing Kong not respond to his overt acts of aggression beyond their initial meeting begins to soften Suko's views on the larger ape. This is further reinforced when they get to Skar King's seat of power and Kong magnanimously helps a beaten down slave gorilla to his feet while cold cocking the bully who struck him, and Skar King's demonstrations of cruelty (including killing Suko's caretaker) push him firmly towards Kong's side.

* HappilyAdopted: [[spoiler:It's implied he becomes Kong's son and the heir to his throne at the end of the film. Considering the bond they've built up over the course of the film, one can assume he's happy with it.]]

* MistreatmentInducedBetrayal: He's loyal to Skar King, up until Skar King callously kills Suko's caretaker for a very minor slight, at which point he becomes loyal to Kong.

* PintSizedPowerhouse: He's comparatively puny compared to Kong and the rest of his tribe as he reaches up to their legs but he is a "scrappy fighter" that has raw primal strength. [[spoiler: The little ape was able to lift and carry Kong's axe, a weapon that's far larger than whole body and destroyed the very crystal that Skar King used to make Shimo yield to his will.]]

!!!'''Appears In:''' ''Series/MonarchLegacyOfMonsters''
!!!'''Species:''' TBA

A territorial, boar-like florafauna that resides within the section of the Hollow Earth called Axis Mundi.

* EmergingFromTheShadows: The first that we see of it, it's lurking in the shadow, with only glimpses of its face and its fogged breath visible, until it stalks into the light towards Cate and we get a better look at it.
* FullBoarAction: As its name suggests, the Brambleboar mostly resembles a wild hog... the size of a large truck, with fang-lined jaws and thorny branches growing from its hide.
* KnowWhenToFoldEm: After it's shot in the eye with an arrow, it runs away.
* MoeGreeneSpecial: The one that shows up attempts to eat Cate, only to get one of its eyes shot out [[spoiler:by Keiko Randa]].
* {{Planimal}}: Like the beasts of Skull Island, it is a hybrid of plant and animal--resembling a massive boar with fanged jaws and thorny branches growing from its hide.

!!!'''Species:''' ''Accipiter Infernum''

A species of large bat-like creatures with hooked beaks, which inhabit the Hollow Earth.

* ArtEvolution: They're much more colourful in ''The New Empire''; their wing membranes are now either bright yellow or red, and they have purple, red, or yellow highlights over their bodies.
* BatOutOfHell: Hellhawks mostly resemble bats and even hang from the ceiling, but have the beaks and talons of birds of prey.
* BrutalBirdOfPrey: Leathery wings and lack of feathers aside, Hellhawks mostly resemble birds of prey, and are shown menacing Kong and his human companions after Godzilla's atomic breath provoked them.
* GiantFlyer: While tiny compared to the likes of Rodan or Mothra, they're still huge by human standards, equal to the size of the largest real-life pterosaurs.
* MixAndMatchCritter: They have leathery bat-like wings and scaly skin, but have beaks and talons resembling those of a bird of prey.
* ShoutOut: Their name and appearance bring to mind the Fell beasts from ''Literature/TheLordOfTheRings'' (the ones in the books are explicitly stated to be beaked, featherless beasts, likely meant as an EvilCounterpart to the eagles).
* ZergRush: How they attack Kong and his human companions.

!!!'''Species:''' Giant arthropod-like vertebrates

A species of large arthropod-like vertebrates that dwell on the Hollow Earth's rocky lands, camouflaging to avoid predators.

* BigCreepyCrawlies: Much larger than any bug. While visually insect-like, they are vertebrates according to the VFX crew, even having visible bones in their concept art. Despite this, they're still smaller than most of the other animals in the Hollow Earth.
* ChameleonCamouflage: Their shells have rock-like textures that allow them to blend in their environments to hide from predators.
* MixAndMatchCritters: They have characteristics of spiders, crabs and scorpions, but have bones and are vertebrates.

!!!'''Species:''' Predatory lizard-like creatures/ Foetodon/ Titanus Doug

A species of large lizard-like animals that live in the Hollow Earth's rocky ecosystem, feeding on smaller animals that cross their path.
-----
* AmbiguouslyRelated: The art book states it was explicitly designed so that it ''could'' be an evolutionary offshoot of Godzilla's ancestral lineage, or possibly even what Godzilla evolved from.
* AscendedMeme: His name, Doug, was coined by the podcast ''It Came From A Monster Movie!'' the first time, then was embraced by director Adam Wingard, and officially acknowledged by the Legendary Pictures Twitter and Instagram accounts. The name of his species is Titanus Doug.
* BreakoutCharacter: Has a total of five seconds of screen time in ''Godzilla vs. Kong'', but somehow became an internet sensation, earning himself the nickname of "Doug" for his sudden popularity. He also makes an appearance early on in ''The New Empire'', even receiving his own Playmates Toy created for the movie, alongside the major Titans that appear in it.
* ChameleonCamouflage: {{Implied}}. The individual seen ambushes one of the scattered Rockclaw and its skin resembles the rocky environment it hunts in.
* MightyGlacier: Notably obese lizards who don't seem to move much beyond ambushes.
* NoNameGiven: Neither the film nor promotional material gives the species or individual a name, though the fans have nicknamed him "Titanus Doug". The film's HBO Max audio description identifies the species as ''Foetodon'', a creature from Peter Jackson's own ''King Kong'' film, but this is not officially confirmed. The trailer for ''GODZILLA x KONG: THE HUNTED'' gives it the name "Doug" as a canonization of the fan-name.
* SingleSpecimenSpecies: {{Averted}}. Only one specimen is seen feeding on a Rockclaw, but two more are shown in an overhead shot watching Kong run through Hollow Earth. The novelization also shows several others of the species feeding on Rock Critters.

[[folder:Warbats]]

!!!'''Appear In:''' ''Film/GodzillaVsKong'' | ''ComicBook/JusticeLeagueVsGodzillaVsKong'' | ''Godzilla x Kong: The Hunted'' | ''Film/GodzillaXKongTheNewEmpire''
!!!'''Species:''' Predatory winged serpents

A species of cobra-like serpentine Sub-Titans with fin-like wings that allow them to fly around the Hollow Earth.

* AlienBlood: They have bright green blood.
* BizarreAlienLocomotion: They're giant cobra-like snakes that can fly by using their oversized hoods as wings.
* ChokeHolds: Like many species of snakes, they're capable of coiling their entire bodies around their captured prey by constriction to keep them still, as one of them attempted to seize the much stronger Kong himself, an attack that actually had him immobile until he had backup on his side to finish it off.
* DemotedToExtra: They reappear in ''The New Empire'', but only as background fauna in the Hollow Earth.
* {{Flight}}: The Warbats are capable of flight using their hood-like wings, which resemble webbed insectoid legs.
* FoodChainOfEvil: One is shown eating a Hellhawk in ''The New Empire''.
* FragileSpeedster: They zoom around the [=HEAVs=] with no problem, but as soon as Kong dives in, the Warbats aren't exactly sturdy enough to withstand his overwhelming strength. Hell, one of them Kong kills in pretty much a single hit.
* GlassCannon: Their serrated fangs can crunch a single [=HEAV=] into bits in one bite and can swerve around in the air a lot faster than the flying vehicles. One of them tried coiling its entire body around Kong's torso to briefly bring the gorilla down to his knees by having him held tightly in its grip. Aside from that, their resilience isn't up to code since the first Warbat died after it was immediately caught by Kong and pierced its head in with a rock, and simple missiles from a [=HEAV=] actually harmed the second one, allowing Kong to be freed and beats it to a pulp before tearing its head off.
* GoodLipsEvilJaws: Their jaws are lipless and lined with needle-like fangs, compared to Kong and Godzilla's lipped mouths.
* TheGreatSerpent: Warbats are gigantic snake-like creatures that can fly.
* HumanHammerThrow: Kong swings the fresh corpse of one Warbat by its tail to attack the second approaching Warbat.
* ImpaledWithExtremePrejudice: The first Warbat Kong grabs ahold of gets hurled headfirst onto a sharpened rock, that just so happened to be conveniently placed on the ground.
* InformedAbility: They can produce and gush out venom within the glands of their hooded wings. Neither of the 2 featured Warbats that fought Kong had the chance to use the venom at all.
* ItCanThink: After seeing what happened to the first Warbat, the secondary one took on Kong indirectly by wrapping itself around his body by using its membranous hood stretched across Kong's face, which is likely an attempt to suffocate him.
* MixAndMatchCritter: They resemble giant cobras, but with crocodile-like jaws and scutes, and with "hoods" that are skin membranes stretched between hugely elongated appendages like bat wings.
* NonIndicativeName: The species may be referred to as Warbat, but by actual appearance, the only bat-like features these guys seem to have are the spiked-tipped membranes within their hoods (although they are not referred by any name in the films).
* OffWithHisHead: Kong does this to one of the Warbats posthumously and drinks the blood out of their skull.
* OurDragonsAreDifferent: Giant, fearless predators living inside the HollowWorld separate from the Earth's surface, who resemble giant cobras with spiny hoods acting as wings that enable them to glide. With some human aid, Kong doesn't have much trouble killing two of them when attacked.
* RoarBeforeBeating: After Kong kills one of the Warbats and gives the remaining one an intimidation display, the Warbat in question responds by rearing up and hissing before it lunges at Kong and tries to kill him.
* SnakesAreSinister: The Warbats are massive winged serpents, described by the official merchandise as being easily capable of ripping through armored vehicles with their fangs, and they're not friendly.
* SuddenNameChange: They were initially called "Nozuki" before the toyline merchandise changed their name to "Warbat". When questioned, neither Warbat's original designer or the director of ''Godzilla vs. Kong'' could explain the name change, although it was suggested to be because "Warbat" was a more marketable name than "Nozuki".
* WeHardlyKnewYe: These monstrosities were only shown onscreen for merely a minute at most, and the 2 of them were quickly killed by Kong not too long after they've already made their presence known.

!!!'''Appears In:''' ''Godzilla x Kong: The Hunted''
!!!'''Species:''' "Ossis Praedator"

A species of vicious, cat-like predator found in the forested regions of the Hollow Earth.
----
* BewareMyStingerTail: It has a series of sharp, bony protrusions running down its back and along its tail, which are stated to be capable of powerful lashing attacks.
* GlassCannon: Noted to be incredibly swift and agile for its size, but it has little durability compared to the likes of Kong and quickly goes down once a foe has a good grasp on it.
* MamaBear: Its species profile notes that females will viciously defend their offspring, which one is shown doing in the story, fighting a giant mech to the death to protect her two cubs.
* MonsterIsAMommy: PlayedWith. [[AxCrazy Raymond Martin]], while hunting for a second Spineprowler, comes across a pair of cubs and tries to [[WouldHurtAChild murder them]], prompting their mother to [[MamaBear react accordingly]].
* MonsterMouth: It has a constantly snarling face with exposed gums and fangs far too big to fit in its mouth.
* NonMaliciousMonster: Despite being classified as a "Destroyer", its role in the comic is just as a vicious animal. One attacks Kong, but quickly retreats once it's clear it's no match for him, and another attacks the Titan Hunter to defend her cubs from the mech.
* PantheraAwesome: A giant, leopard-like kaiju that is said to be one of the Hollow Earth's most vicious predator species.

Pack-hunting canine/boar Titans who Kong hunts himself in the Hollow Earth.
----
* AlienBlood: Their blood is bright green.
* AlwaysABiggerFish: Are pretty terrifying-looking creatures on their own. Kong hunts them for breakfast.
* FullBoarAction: Resemble a kaiju-sized ''Daeodon'', an extinct scavenging ungulate known as the "hell pig".
* KnowWhenToFoldEm: The pack retreats after Kong ''graphically'' kills several of them and shows them mutilating the body of the last one to fall into his traps they run off.
%%Verification? * ShoutOut: They resemble the Wargs from ''Film/TheLordOfTheRings''.

!!!'''Appear In:''' ''Film/GodzillaXKongTheNewEmpire''

* AmphibianAtLarge: A very large frog with an inflatable throat-sac larger than the rest of its body.
* MightyRoar: Played with. It's small for a Titan, but its vocalizations are extremely loud and nigh-identical to the roars of Kong's species. This [[FooledByTheSound leads to Kong mistaking one's bellowing for another Kong]], only to be disappointed when he comes across the Parrot Frog making them.
* VoiceChangeling: The Parrot Frog is shown mimicking Kong's roars, tricking him into thinking there's another one of his kind. It's likely that the Parrot Frog can mimic other sounds, but this isn't demonstrated in the film

A colossal eel-like titan inhabiting a large lake.

* AlienBlood: It has green blood like the Wart Dogs. Although, strangely, its innards and flesh are still red.
* KilledOffscreen: One minute it's fighting Kong while Suko runs off, the next it cuts to Suko being caught up to by Kong who shows up with the creature's beheaded body.
* SeaSerpent: It is a large serpentine Titan that lives in a lake in Hollow Earth and preys on anything that enters its territory. Suko attempts to use one to kill Kong, but Kong is able to overpower and kill it instead.
