History Characters / AbraxasHrodvitnonTitansAndOtherCreatures

* HiddenDepths: Despite his snarky behaviour towards Monster X; [[NoodleIncident he's apparently reared Titan/s outside his own species before]], and it's {{lampshaded}} that he has some genuine words of wisdom and good advice.

'''[[center: [- [[Characters/AbraxasHrodvitnon Main Character Index]] -]]]'''

* OOCIsSeriousBusiness: Vivienne knows something is wrong when Ni/Elder Brother halts his usual ferocious behaviour to gently trace her features with a claw and draw her blood.

* AlternateAnimalAffection: According to [[https://hrodvitnon.tumblr.com/post/709158137834471424/ this drabble]], his physical displays of affection include slithering up one's arm and booping heads.

* ExpressiveHair: The tendrils growing on his jawline quiver to express his mood. [[https://hrodvitnon.tumblr.com/post/709158137834471424/ This]] non-canon post by the author indicates that after Manda matures, the other tendrils along his body will undulate in specific ways to reflect his mood.

* CaptainErsatz: As the love-baby of TheVirus and TheAssimilator with a HiveMind, MindHive and a good deal of BodyHorror thrown in, [[https://hrodvitnon.tumblr.com/post/656515418850230272/ the author]] admits the Many are very closely based on [[Characters/HaloOther the Flood]] and Film/TheThing.

* NurtureOverNature: The [=AbraxasVerse=] Timeline reveals Monarch are attempting to [[InvokedTrope invoke]] this on the Zmeyevich in their custody in case they've inherited any of Ghidorah's biologically-ingrained violent impulses.

* JerkWithAHeartOfGold: He's the most unpleasant towards San and Vivienne out of the Titans they've interacted with so far, but he also stays true to his duty to mentor them in his own snarky way.

* EvilHasABadSenseOfHumor: He shares this with Ichi/Eldest Brother (see Ghidorah's folder), as he's the one who does the leg-breaking in Chapter 16.

* EvilSoundsRaspy: Being a shed skin of Ni/Elder Brother, he would have the same voice. See Ghidorah's folder for details.

!!!'''Scientific name:''' ''Titanus Ghidorah''
A malevolent extraterrestrial Titan which was responsible for instigating the Titan Mass Awakening before being defeated by Godzilla. It consists of three draconic brothers with a single body, who each have control of one of the three heads: San (later San's AlternateSelf, San-2/San-Who-Could-Have-Been) who is known to the other heads as "Youngest Brother" or "the Third"; and the "Eldest Brother" (the central head, Ichi, "the First") and "Eld'''er''' Brother/Young'''er''' Brother" (the right head, Ni, "the Second").

!! Tropes applying generally or to all three heads

* AdaptationalAbomination: Ghidorah was already portrayed in Franchise/MonsterVerse canon as a DraconicAbomination; but in ''Abraxas'', its leftover head's PsychicPowers have an even more intense BrownNote effect on anyone who spends too much time near it than anything displayed in ''Film/GodzillaVsKong''. It's also worth noting, the ''Godzilla vs. Kong'' novelization states Ghidorah's skull is composed of metals and minerals that are rare on Earth, whereas in [=AbraxasVerse=], Ghidorah's biology mostly consists of elements that ''aren't even on the periodic table''.
* AdaptationalBadass: Besides [[Characters/MonsterVerseKingGhidorah the points racked up by]] [[Characters/MonsterVerseKingGhidorah MonsterVerse canon Ghidorah]] relative to earlier licensed continuities' portrayals, there's also the fact that this story's version of Ghidorah [[spoiler:was able to break free of its alien former-masters' control without any assistance, if they even had any real control over it to begin with (but from [[https://hrodvitnon.tumblr.com/post/645147573238333440/ what the author has said]], it's possible that those aliens probably just didn't value their lives enough to try placing restraints on their own creation)]]. Furthermore, Ghidorah's PsychicPowers even when it's reduced to a single head are demonstrably more intense here than in [=MonsterVerse=] canon, and Ghidorah in this story is able to regenerate fully FromASingleCell with all three minds intact (whereas [=MonsterVerse=] Ghidorah's remains were an UndeadAbomination that only demonstrably retained Ghidorah's SoulFragment).
* TheAgeless: Its {{Backstory}} indicates as much, confirming that it's been around for ''eons''.
* AndYourLittleDogToo: [[spoiler:In Chapter 17, it decides on a whim to try assimilating Thor into the Many and then ripping Mothra limb from limb, solely so that it can see Godzilla and Monster X's reactions]].
* ArtifactOfDoom: The severed Ghidorah head inside the abandoned Monarch outpost, which is implied to still have some of Ghidorah in it after San's consciousness has left.
* TheAssimilator: [[spoiler:Its ultimate plan for Vivienne -- it intends to turn her into its fourth head (Shi). In Chapter 17, Ghidorah manages to partly assimilate Thor into its partly Many-composed body]].
* AxCrazy: Ghidorah (particularly Ichi/Eldest Brother and Ni/Elder Brother) is just as relentlessly depraved, cruel and bloodthirsty here as the three-headed monster has ever been in any licenced ''Franchise/{{Godzilla}}'' continuity. Ghidorah's backstory here expands on the "crazy" when describing what caused Ghidorah to become the sadistic OmnicidalManiac we all know it as.
* BackFromTheDead: San states that Ghidorah can regenerate and return from death via its HealingFactor so long as any trace of its DNA remains -- apparently, San and his brothers have died and resurrected this way before -- and thus Ghidorah will one day return via the decapitated head or its DNA. [[spoiler:It eventually comes true.]]
* BadassBoast: Has this for a Bone Singer who communicated with it, in the past in Chapter 5:[[note]]The below capitalization, font and lack of grammar is how each of the trio's dialogue is respectively written in the fic[[/note]]
--->'''Ichi''': '''WE ARE DEATHLESS'''\\
'''Ni''': WE ARE ETERNAL\\
'''Ichi''': '''WE ARE THE DESTROYER OF WORLDS'''\\
'''Ni''': CONSUMED EMPIRES OF FLESH AND BONE AND METAL\\
'''San''': we live forever cut off our heads and they will grow back\\
'''Ichi''': '''THE HEAD IS THE SEAT OF THE SOUL'''\\
'''Ni''': THE HEAD IS THE SEAT OF THE SOUL\\
'''San''': the head is the seat of the soul
* BadBoss: Ghidorah actually regards the Titans it once commanded as "lowly beasts" who have no higher purposes than being lapdogs to Ghidorah's whims.
* BeautyIsBad: It's acknowledged as having been a beautiful and elegant creature, as utterly evil and destructive as it was. [[spoiler:In its incomplete, BodyHorror form, the heads are about the only part of it that retain this]].
* BeingTorturedMakesYouEvil: [[spoiler:Ghidorah's creators methodically tortured it, implicitly to make it a more effectively violent BioweaponBeast, and this was the beginning of Ghidorah's path into evil before it exterminated the Makers in revenge. The [[TerribleTicking Old Noise]] the Makers had programmed into Ghidorah's minds finished what the Makers started, [[SlowlySlippingIntoEvil slowly tearing apart and erasing what goodness Ichi/Eldest Brother and Ni/Elder Brother still had in them]] until Ghidorah became the vicious monster we all know it as]].
* BellyMouth: [[spoiler:Keizer Ghidorah has a giant, vertical mouth with teeth in its Many-made chest]].
* BigBad: It casts a lingering influence on San and Vivienne. [[spoiler:Once it starts coming BackFromTheDead, it serves as the main Kaiju antagonist of the story]].
* BigScrewedUpFamily: Its EvilPlan [[spoiler:after regenerating]] involved [[spoiler:inflicting BeingTorturedMakesYouEvil on their "[[AntiAntichrist sister-daughter]]" Vivienne to make her like them, with the Many as Ghidorah's thralls]], and both San-2/Youngest Brother and the Many outright call it a family.
* BioweaponBeast: Once, long ago. [[spoiler:It's implied the alien civilization who turned Ichi, Ni and San into Ghidorah intended them to be this]].
* BodyHorror: Once the MonsterDelay ends in Chapter 17, it's revealed that [[spoiler:Ghidorah's unwhole body, which it's incorporated the Many into]], is so horrible to behold that the entire G-Team go pale-faced despite themselves.
* BreakThemByTalking: [[spoiler:Is attempting to drive Monster X down a StartOfDarkness, using techniques varying from tempting to belittling, to striking when Vivienne is mentally vulnerable.]]
* BrownNote: The decapitated head's psychic influence seems to cause this, driving to suicide those who don't suffer TheCorruption type SanitySlippage. According to [[https://hrodvitnon.tumblr.com/post/691622393957023744/ Word of God]], there's a constant risk that any undisciplined Bone Singer who doesn't have their guard up around Ghidorah can be psychically pushed and negatively influenced by its telepathy.
* CannotTellALie: Ghidorah has never had a concept of dishonesty before, and even metaphors alluded it: [[spoiler:according to [[https://hrodvitnon.tumblr.com/post/648508725162803200/ Word of God]], this has caused Ghidorah to take the most literal interpretation of humanity's mythology when it read our socio-cultural knowledge through the Many]]. How straight the trope is played actually depends on the head: according to [[https://hrodvitnon.tumblr.com/post/697040294509690881/ the author]], whilst none of the heads technically lie; [[DownplayedTrope Ichi/Eldest Brother is happy to use]] {{exact words}} [[DownplayedTrope and mislead others]], whereas Ni/Elder Brother (like San and presumably also like San-2/Youngest Brother) sees anything less than complete {{brutal honesty}} as a disinteresting waste of his own brain-power.
* ClipItsWings: During the [[spoiler:Chapter 17]] battle, Godzilla burned a hole through one of Ghidorah's wings with his Atomic Breath to disable its flight advantage.
* ComicBookFantasyCasting: The author has described what Ni and Ichi's mental voices sound like [[https://hrodvitnon.tumblr.com/post/623720240777412608 here]], and San-Who-Could-Have-Been/Youngest Brother has the same voice as the main San ([[https://www.youtube.com/watch?v=A2p2XI5Mg50 the dragon Grigori]]) -- also see [[https://hrodvitnon.tumblr.com/post/621194625830600704/ here]] for an example of what Ichi would sound like when he raises his voice based on his casting.
* CompositeCharacter: King Ghidorah and [[spoiler:Keizer Ghidorah]] are considered by [[https://twitter.com/GodzillaWiki/status/1358783594102198275 Wikizilla]] to be separate characters due to Toho officially making separate trademarks for them. In ''Abraxas'', [[spoiler:they're the same character in different forms]].
* TheCorrupter: [[spoiler:This seems to be its plan for Vivienne, utilizing BreakThemByTalking and attempting to drive her into a full SanitySlippage so it can turn her into another AxCrazy extension of Ghidorah]].
* CreateYourOwnHero: It's done this by planning before San's decapitation to bring Vivienne BackFromTheDead as a part-Ghidorah hybrid. If Ichi/Eldest Brother had just been able to settle for killing her and letting her stay dead, the course of events from when [[spoiler:Ghidorah starts regenerating]] would probably go differently.
--->'''Vivienne:''' ''[to the Many]'' "''Your 'great one' should have let me stay dead!''"
* DarkLordOnLifeSupport: PlayedWith. [[spoiler:It's reliant on its own surviving DNA traces to regenerate [[FromASingleCell From a Single Head]] after it was previously obliterated, and until it can fully regenerate, it's reliant on the Many to act physically]].
* TheDarknessGazesBack: During Ghidorah's confrontation with [[spoiler:Thor underground]], it became visible by its glinting eyes when enraged, then also by [[PowerGlows the glow of its Gravity Beams charging]].
* DecompositeCharacter: [[spoiler:Ghidorah here becomes [[Characters/GodzillaTheGhidorahs Keizer Ghidorah]] in spirit after merging with the Many and forming a pair of forelegs, making this continuity's version of Keizer Ghidorah a separate character from Monster X]].
* {{Dehumanization}}: A variation. [[spoiler:It considers any of its heads that have detached from Ghidorah's main body and become autonomous creatures to be nothing more than "shed skins" or "shadows" which are inferior to Ghidorah, despite said shed skins retaining their personalities]]. [[https://hrodvitnon.tumblr.com/post/690309147799011328/ Word of God]] has talked more about how and when Ghidorah developed this attitude in its backstory.
* {{Determinator}}: {{Implied}}. Compared to the old Toho incarnations who would flee back into space when defeated, in this story, it seems Ghidorah truly will not stop until it's successfully conquered and destroyed the Earth before it can move on to doing the same to another world. Bear in mind, it's explicitly confirmed in this story that Ghidorah is capable of interstellar travel (whereas ''King of the Monsters'' kept Ghidorah's history before falling to Earth [[MysteriousPast shrouded in mystery]]), yet it tries to kill Godzilla and destroy his world ''every'' time it comes back from death.
* DetrimentalDetermination: Not only did Ghidorah unwittingly pull a CreateYourOwnHero with Vivienne's transformation into a half-Ghidorah Titan, but it [[spoiler:remains fixated on getting Monster X back and completing its end-goals for Vivienne at all costs. This ultimately leads to Monster X alerting Godzilla and his allies (both human and Titan) to Ghidorah's hiding place once Ghidorah has had Monster X brought there; triggering the FinalBattle, and ruining Ghidorah's chances to remain in hiding until it was fully regenerated]].
* DraconicAbomination: True to its film characterization, Ghidorah is an inexplicably powerful and ancient creature even by the standards of the Titans, and has a HealingFactor and biology that can't be explained by human science, [[UndeadAbomination not to mention the results of experimenting on its DNA]].
* TheDreaded: Vivienne completely feared Ghidorah when it was still frozen, humans who encountered Ghidorah during the Mass Awakening tend to be left with some psychological trauma to varying degrees, and both humans and Titans alike take the idea of Ghidorah one day returning [[FromASingleCell From a Single Head]] very gravely.
* ElementalAbsorption: San explicitly says that Ghidorah can feed on electrical energy from manmade constructs and from other bio-electrical Titans to make itself stronger.
* EmergingFromTheShadows: {{Subverted}}. During [[spoiler:Keizer]] Ghidorah's confrontation with [[spoiler:Thor]], it ''looks'' like Ghidorah is going to emerge to attack, but then it pulls back [[spoiler:and has its EliteMook attack him]].
* EnemyToAllLivingThings: It threatens pretty much all other life, it's confirmed here to be a serial PlanetDestroyer, and it's despised by Earth's native Titans (forces of nature embodied) as "the Enemy".
* EvilCannotComprehendGood:
** Multiple posts [[https://www.tumblr.com/hrodvitnon/677549009646272512/ by]] [[https://www.tumblr.com/hrodvitnon/685085904520527872/ the]] [[https://www.tumblr.com/hrodvitnon/703365355024859136/ author]] have made it clear that unlike San, Ichi/Eldest Brother and Ni/Elder Brother have absolutely no capacity to [[HeelFaceTurn change for the better]]: there's simply not enough good in them anymore. If Ichi and Ni were confronted with anything that challenged their [[StrawNihilist straw nihilism]], they would have an IgnoredEpiphany or just immediately brush it off.
** [[spoiler:{{Subverted}} with San-2/Youngest Brother in [[https://www.fanfiction.net/s/13357907/17/ Chapter 17]]. He at first can't understand why Vivienne won't respond to him or his brothers the way she responds to Mothra and San, but after he has a lengthy psychic talk with Viv and San coupled with seeing Thor's memories of his family, San-Who-Could-Have-Been ends up making a RedemptionEqualsDeath]].
* EvilCounterpart: It has a GoodCounterpart in Monster X, who ultimately has similar powers, a similar TwoBeingsOneBody nature and [[spoiler:a similar origin]] to Ghidorah but is benevolent and wants to live in peace, in contrast to Ghidorah's malicious cruelty and [[OmnicidalManiac Omnicidal Mania]]. Ichi/Eldest Brother specifically is an Evil Counterpart to Vivienne (see below).
* EvilerThanThou: It's far too much for Jonah to control even when it's mostly dead, [[spoiler:leading to Ghidorah becoming the one pulling Jonah's strings]]. Driving this trope home is the [[spoiler:regenerated heads]]' utter contempt for Jonah in Chapter 13.
* EvilIsHammy: Sometimes, especially with Ichi/Eldest Brother, as the BadassBoast and the NoIndoorVoice demonstrate, although it's relatively subdued.
* EvilLaugh: It's hinted in this story that some of the times when Ghidorah's heads produce their high-pitched roars (which ''Franchise/{{Godzilla}}'' viewers have historically compared to deranged cackling), they really ''are'' cackling in their [[AnimalTalk Kaiju Talk]].
* EvilMakesYouUgly: Both San and Mothra consider Ghidorah's utilization of the Many to be a new debasement even by Ghidorah's standards, and... Well, if [[spoiler:Ghidorah's part-Many temporary body]] could make [[Film/GodzillaKingOfTheMonsters2019 the military team who fought at Washington DC and Boston]] want to throw up, that's gotta be saying something.
* FamilyThemeNaming: Although Ichi, Ni and San are technically nicknames that Vivienne gave to Ghidorah's three heads rather than being considered by Ghidorah its real names, nevertheless, not only Vivienne but also San-2/Youngest Brother think she'd be called Shi[[note]]The Japanese number four, just as Ichi, Ni and San are one, two and three in Japanese[[/note]] if [[spoiler:Ghidorah were to succeed in turning her into its fourth head]].
* FatalFlaw: Like in ''King of the Monsters'', it's Ghidorah's overt thirst for senseless agony that does it in. Ichi/Eldest Brother pulled a CreateYourOwnHero by ordering San to turn Vivienne into an ArtificialHybrid because just eating and killing her wasn't enough to satisfy the former, and [[spoiler:Ghidorah might have actually won at the story's end if it had gone through with fleeing to the HollowEarth instead of going back to have some "fun" at its enemies' expense out of sheer spite and malice]].
* FauxFlame: [[spoiler:Keizer Ghidorah's red-themed storm]] makes the sky look like it's alive with hellfire.
* {{Foil}}: Apart from the EvilCounterpart, Ghidorah is this to Alan Jonah. Despite their MirrorCharacter (see below), Ichi/Eldest Brother and Ni/Elder Brother have absolutely zero redeeming qualities and are very much EvilerThanThou. Jonah is ultimately a mortal SmugSnake, whereas Ghidorah is technically a SmugSuper as an Alpha-class PhysicalGod.
* ForTheEvulz: [[https://hrodvitnon.tumblr.com/post/649738995841024000/ Word of God]] comments that Ghidorah will personally wipe out some species just for pleasure during its conquest of a planet.
* FreudianExcuse: It's lived for billions of years after the incident in its {{Backstory}} which made it a WoobieDestroyerOfWorlds and led to it becoming so evil.
* FromASingleCell: Ghidorah can regenerate its entire body and all three heads' minds from just a single decapitated head, although it implicitly takes years for it to fully regrow without outside assistance, probably not least because the head needs to conserve or expand its internal power according to [[https://hrodvitnon.tumblr.com/post/689311522082668544/ Word of God]].
* FromNobodyToNightmare: Ichi, Ni and San began their shared existence as a small, weak type of animal that was ''not'' at the top of the food chain, on some faraway alien world. Eons later, they're a spacefaring, murderous DraconicAbomination that has ravaged entire worlds that once had intelligent life, and they're Godzilla's nightmarish ArchEnemy on Earth.
* FullyEmbracedFiend: An [[spoiler:alien wild animal to alien giant PersonOfMassDestruction]] variation, but Ghidorah is this compared to Monster X; having long ago grown to like and then embrace its sadistic instincts [[spoiler:which were hardwired into it against its will]].
* GeneticMemory: With time, it can regenerate all three heads' individual personalities and memories from just a single decapitated head.
* GeniusBruiser: It's vicious but not dumb at all, and it's highly tactical.
* GenocideBackfire: It's responsible for exterminating the rest of Thor's people long ago, and Thor [[spoiler:in the FinalBattle plays a significant part in killing Ghidorah]]. It's also heavily implied that Ghidorah caused or at least contributed to the near-extinction of [[ArchEnemy Godzilla]]'s species.
* AGodAmI: It's implied Ghidorah's heads view their single-bodied self this way, and at best consider the terrestrial Titans that oppose them to be second-rate.
* GoodColorsEvilColors: Ghidorah's gold color scheme becomes the Evil Color compared to Monster X's bone armor being infused with visible silver traces, in addition to a BrightIsNotGood / DarkIsNotEvil contrast after Monster X's second {{Metamorphosis}}.
* GreaterScopeVillain: Besides its points listed under PosthumousCharacter, its PsychicPowers also caused Jonah's SanitySlippage and the creation of the Many. [[spoiler:{{Subverted}} when Ghidorah's three minds regenerate, and it takes over from [[DiscOneFinalBoss Jonah]] as the true BigBad of the story]].
* HatedByAll: Everyone InUniverse, from Viv and San to the Titans Ghidorah fought or controlled to the humans who were in any way involved in fighting it during ''King of the Monsters'', hate Ghidorah's guts, [[spoiler:and the feeling renews when Ghidorah comes BackFromTheDead]]. [[spoiler:San-2/Youngest Brother is somewhat exempt from this trope during and after his RedemptionEqualsDeath, but the other two heads not so much]].
* HateSink: It's responsible for [[spoiler:relentlessly and viciously trying to get under Viv and San's skin via the PsychicLink, and the heads all to varying degrees take glee in physically or psychologically hurting something. Ghidorah's EvilPlan to undo all of Vivienne's work towards mental recovery and reduce her to an irrevocably AxCrazy monster, its willingness to forcibly use her as a monster BabyFactory if it'll make her scream to that end, and its wish to physically separate her from San (with no small amount of needless cruelty) and turn her into Ichi, Ni and San-2's fourth head]]; all of these go quite a way to purge any Rooting for the Empire tendencies that even a sadistic reader might otherwise have, and they make the reader very much root against Ghidorah and want it to ''fail'' in its Evil Plan as well as making Ghidorah quite loathsome.
* HavingABlast: In Chapter 17, it's revealed that [[spoiler:Keizer Ghidorah has gained Godzilla's ability to pull this off, due to the Many assimilating Godzilla's dorsal plate fragments leftover from the events of ''Godzilla: Aftershock'']].
* HealingFactor: It turns out that it ''can'' regrow FromASingleCell with enough time.
* HisNameReallyIsBarkeep: In the film, Ghidorah's name was merely what ancient humans called it, whereas it's explicitly shown in the fic that it's also the name by which Ghidorah's heads identify themselves. Special ancient humans who were capable of [[AnimalTalk Kaiju Talk]] probably picked up and recorded the name.
* HiveQueen: [[spoiler:Ghidorah's three minds control the Many, which are originally created from Ghidorah's DNA, this way]].
* HoistByHisOwnPetard: Of the CreateYourOwnHero kind. Things would've probably gone very differently if Ghidorah hadn't resurrected Vivienne to turn her into an ArtificialHybrid. What's more, Ghidorah is directly responsible for [[spoiler:instigating Monster X's metamorphosis into its final form, enabling them to contribute heavily to the final fight against Ghidorah]].
* HostileTerraforming: San's memories confirm that Ghidorah has remade alien worlds it conquered before Earth in its own image, via converting the skies into a planet-wide version of [[TheStormbringer the tempest that forms around Ghidorah on Earth]] (which would logically spell certain extinction for any lifeforms that were neither highly adaptable nor used to similar environmental conditions), although it should be noted that Ghidorah's character expansion in this fic leans into the character interpretation briefly suggested in the ''King of the Monsters'' novelization; that Ghidorah is acting out of a simple appetite for pure destruction and dominance rather than any desire to carve out any lastingsuitable habitat for itself. That being said, [[https://www.tumblr.com/hrodvitnon/703365355024859136/ Word of God]] has said that ''if'' Ghidorah feels like lingering on a world it's conquered and ravaged before it moves on, it'll probably start ''literally'' xenoforming the planet to Ghidorah's own liking for real.
* {{Hypocrite}}: Ichi/Eldest Brother is enraged when [[spoiler:San]] points out [[spoiler:in Chapter 14]] that Ghidorah's [[spoiler:creation and utilization of the Many]] is a lot like what [[spoiler:the aliens who turned them into Ghidorah]] did to them. [[https://hrodvitnon.tumblr.com/post/677549009646272512/ Word of God]] comments that Ghidorah really wouldn't care if it realized its hypocrisy and would rationalize the contradiction. See below for another example.
* IconicAttributeAdoptionMoment: [[spoiler:Keizer Ghidorah starts out with corpse-filled skin and gangly forelegs, but as its body reshapes itself, it looks increasingly faithful to the original [[Film/GodzillaFinalWars Keizer Ghidorah movie design]]]].
* ImMelting: [[spoiler:Keizer Ghidorah's body minus its severed head is melted down and vaporized, and then the severed head is cooked and melted by Monster X]].
* ImmortalsFearDeath: {{Averted}} and somewhat {{deconstructed}}. Whilst Ghidorah isn't exactly afraid of death, it apparently doesn't fear it much more than the average person either. According to [[https://hrodvitnon.tumblr.com/post/709885319486554112/ Word of God]], this is mainly rooted in Ghidorah's self-awareness that it will always come back from death so long as even a small piece of it survives (at least, that's why Ichi/Eldest Brother, [[spoiler:who had a VillainousBreakdown when Monster X suggested he could be killed permanently]], isn't overly afraid of dying). [[spoiler:Even San-Who-Could-Have-Been/Youngest Brother is less thanatophobic than the main San, having never been terrified by seeing Vivienne's memories of temporary death]].
* InstantExpert: [[spoiler:The Many's HiveMind enables Ghidorah to read the socio-cultural knowledge of all the Many's human victims at its leisure]].
* KarmicDeath: [[spoiler:The partly-regenerated Ghidorah is eventually beaten in battle by an alliance of the TwoBeingsOneBody Titan it caused so much pain to, the Queen of the Monsters it previously killed, said Queen's symbiotic partner and implicit mate, the Thunderer whose son it brutally slaughtered and whose kind it exterminated, and several of the Titans whom it enslaved and tried to manipulate into destroying their own planet. Monster X, who has arguably suffered the most pain by Ghidorah's actions, is the one who finishes Ichi/Eldest Brother off once the latter's head is all that's left]].
* KickTheSonOfABitch: [[spoiler:All three of its minds deride Jonah as nothing more than a tool who served his purpose]]. {{Downplayed}} by Ichi/Eldest Brother when [[spoiler:in Chapter 16, he lets San-2/Youngest Brother pick a fight with [=MaNi=]/Elder Brother for Ichi's own amusement]].
* KnightOfCerebus: {{Downplayed}} in that the work is already dark and edgy even without Ghidorah's direct presence. But once [[spoiler:Keizer Ghidorah returns to center stage, things turn even more serious: it torments Monster X underground, and it absorbs an entire city's population in advance of the MonsterDelay's end]]. It helps that whereas Alan Jonah is a SmugSnake and [=MaNi=]/Elder Brother is StupidEvil, Ghidorah is more of a SmugSuper.
* LargeAndInCharge: [[spoiler:It's regenerated enough to tower above [[EliteMook MaNi/Elder Brother]] and logically the Many's other Skullcrawler {{Mind Hive}}s]], in Chapter 17.
* LeakingCanOfEvil: While it was frozen, its heads were still partly conscious and still able to exert a limited psychic and electromagnetic interference.
* LifeEnergy: Ghidorah can suck this power out of other living creatures via VampiricDraining like it tried to do to Godzilla in ''King of the Monsters'', but more than that, [[https://hrodvitnon.tumblr.com/post/689311522082668544/ Word of God]] says that Ghidorah's [[LosingYourHead severed pieces]] utilize a kind of onboard backup storage of its life energy to stay animate, and that this energy store can run out if it isn't well-charged.
* LightIsNotGood: Like in [=MonsterVerse=] canon, Ghidorah produces lightning [[spoiler:even in its Keizer form]], and it's a monster in '''every''' sense of the word. [[https://hrodvitnon.tumblr.com/post/688985016945000448/ Word of God]] even comments on Ghidorah, "[[MultipleHeadCase The Three]] came in Light".
* LogicalWeakness: Apparently, Ghidorah's electrical powers can be crippled by a [=MUTO's=] {{EMP}}.
* LookOnMyWorksYeMightyAndDespair: Quoted in verbatim by Monster X in Chapter 17. Ghidorah's efforts with Vivienne can be considered a villainous [[InvertedTrope inversion]] of the smaller scale version of this trope: Ghidorah's [[spoiler:regenerating minds]] frankly invest ''a lot'' in trying to make Vivienne [[StartOfDarkness become like Ghidorah]], [[spoiler:but it ends with Monster X contributing to Ghidorah's defeat and becoming a protector Titan, the complete antithesis to what Ghidorah wanted]].
* MassHypnosis: The severed head's psychic influence affects a number of Jonah's paramilitary, inducing {{Sanity Slippage}}s and causing those who aren't DrivenToSuicide to [[spoiler:aid Ghidorah's resurrection]].
* MasterOfYourDomain: After the middle head ate Vivienne alive, her body was willfully regurgitated into the left head's (San's) neck to keep her intact so she could be revived and biologically reshaped to Ghidorah's desires, though not before she'd been partly digested by Ghidorah's stomach acids.
* MeaningfulName: [[https://www.tumblr.com/hrodvitnon/699677927317569536/ Word of God]] suggests that the [[InSeriesNickname Japanese numeral nicknames]] which Vivienne originally gave the three heads, specifically which head she gave each nickname to, was influenced by Ghidorah psychically leaking details about itself into Vivienne's head, like which head was the First and which head was the Third.
* MindHive: [[spoiler:Ghidorah has assimilated the Many into itself to make itself mobile whilst its regeneration is incomplete. And well, most of the resulting body looks like a medieval artwork of eternal damnation at first]]. [[https://hrodvitnon.tumblr.com/post/687098471816314880/ Early planning notes by the author]] even compared the connections among Ghidorah's attached heads to a HiveMind.
* MindRape: Ghidorah has used its PsychicLink to [[spoiler:Monster X]] to torment them, inducing excruciating seizures and just intrusively attempting to shout [[BreakThemByTalking breaking words]] at [[spoiler:Vivienne which, in Ichi/Eldest Brother's case, get increasingly sensual]]. The BrownNote effect that the decapitated Ghidorah-head has on Jonah's paramilitary is outright ''torturous'' for some humans in the long term.
* MonsterDelay: [[spoiler:It isn't until one chapter after Ghidorah's first appearance in the flesh following its partial regeneration and use of the Many that we see what its body below the necks looks like]].
* MoralMyopia: It despises [[spoiler:its long-dead alien makers]], yet none of its attached heads seem to quite realize (or just don't care) that they've become exactly the same as them – something which San after his HeelFaceTurn calls his brothers out on. Ichi/Eldest Brother in particular is extremely vindictive when anything besides himself and his brothers reminds him of [[spoiler:the makers]]. [[https://www.tumblr.com/hrodvitnon/677549009646272512/ The author]] said that the heads honestly wouldn't care if they realized their hypocrisy and would just rationalize that they're a god while the Makers were mortal.
* MoreThanMindControl: [[https://hrodvitnon.tumblr.com/post/684182475131551744/ Word of God]] indicates it psychically and subtly manipulated [[spoiler:Jonah before his SanitySlippage got really bad, giving his thoughts a slight ''nudge'' that ultimately made him obsessively believe he could resurrect a lost loved one]]. [[https://hrodvitnon.tumblr.com/post/691622393957023744/ The author]] further commented that anyone who's able to communicate with the Titans but lacks the necessary training to resist Ghidorah's BrownNote is vulnerable to being "influenced" by Ghidorah's psychic power into acting a certain way.
* MotherOfAThousandYoung: Gender-flipped, but Ghidorah is this by the end of the fic; having effectively spawned Monster X, [[TheVirus the Many]] and an unknown number of [[HalfHumanHybrid Zmeyevich]].
* MotiveDecay: Ghidorah is revealed via its backstory to be an InUniverse case. [[spoiler:It began killing beyond its TurnedAgainstTheirMasters because it was at first just trying to make "[[TerribleTicking the Old Noise]]" stop, and it aimed to kill {{Asshole Victim}}s; with [[https://hrodvitnon.tumblr.com/post/690309147799011328/ Word of God]] even suggesting that at least ''some'' of these early victims Ghidorah targeted were [[ButWhatAboutTheAstronauts extraplanetary survivors]] of [[AbusivePrecursors the Makers]]' species]]. As time passed however, Ghidrah wholly devolved into an OmnicidalManiac, concerned only with hatred of all life that even vaguely resembles [[spoiler:the Makers]] and with satisfying its endless bloodlust.
* MultipleHeadCase: It consists of three brothers, each acting as an individual mind for one of its three heads, and it can regenerate back-up duplicates of them if Ghidorah or one of its heads is destroyed or is severed intact.
* NamesToRunAwayFromReallyFast: It's called the Destroyer of Worlds for a reason.
* NearVillainVictory: [[https://hrodvitnon.tumblr.com/post/668150068002553856/ Word of God]] confirms that Vivienne comes within ''a hair's breadth'' of going irrevocably AxCrazy as Ghidorah wanted of her, in Chapter 16. It's suggested in Chapter 17 that [[spoiler:if it weren't for a combination of Monster X weakening Ghidorah and Ghidorah choosing to forego retreating to the [[HollowEarth Realm Below]], Ghidorah might have succeeded in corrupting Vivienne and destroying the world from the inside-out]].
* NiceJobFixingItVillain: As seen in the story and [[https://hrodvitnon.tumblr.com/post/672405103227060224/ further elaborated on by the author]]; not only did Ghidorah CreateYourOwnHero, but [[spoiler:by making Monster X's final form more powerful, Ghidorah ends up giving its enemies a very powerful extra ally against in the fight against Keizer Ghidorah]].
* TheNightThatNeverEnds: San's memories indicate that Ghidorah converted the skies of alien worlds it previously attacked into a global version of the alien superstorm which forms around Ghidorah on Earth, which naturally blotted out those worlds' sunlight permanently among the storms' other destructive effects. [[https://www.tumblr.com/hrodvitnon/703365355024859136/ Word of God]] confirms that if Ghidorah hadn't been stopped during the Mass Awakening, it would've covered the Earth in sunlight-blocking and biosphere-ravaging {{perpetual storm}}s.
* NobodyCallsMeChicken: [[spoiler:Thor]] accusing it of being afraid to face him successfully pissed it off [[spoiler:in Chapter 17]].
* NoIndoorVoice: Its heads' voices are usually shouting or screaming according to the narration, except for after the OOCIsSeriousBusiness.
* NoOntologicalInertia: [[spoiler:When Keizer Ghidorah is killed, the storm it was generating disperses within a matter of minutes]].
* NotEnoughToBury: [[spoiler:Keizer Ghidorah gets thoroughly vaporized, in an attempt to ensure Ghidorah can't regenerate again]].
* NotSoInvincibleAfterAll: {{Discussed}}. Ghidorah considers itself to be "deathless", but in Chapter 17, Monster X points out to [[spoiler:Ichi/Eldest Brother]] that Ghidorah will die permanently if its enemies can find and destroy all its remains after killing it.
* TheOlderImmortal: Whereas the Titans native to Earth are believed to be thousands, millions or hundreds of millions of years old depending on the individual; [[https://hrodvitnon.tumblr.com/post/637986068089716737/ Word of God]] describes Ghidorah as being literally eons (billions of years) old.
* OmnicidalManiac: It's made clear that from Ghidorah's perspective, everything besides itself is either a toy for extending its destructive rampage, or otherwise consists of food and insects which exist solely to be played with and then killed. As revealed by San's memories and further elaborated on by [[https://hrodvitnon.tumblr.com/post/649738995841024000/ Word]] [[https://www.tumblr.com/hrodvitnon/703365355024859136/ of]] [[https://hrodvitnon.tumblr.com/post/685085904520527872/ God]], Ghidorah has been traveling from world to world for eons, wreaking biosphere mass extinction (if not ''[[ApocalypseHow/Class6 total]]'' extinction) on each one while asserting its dominance, and systematically hunting down any undesirable indigenous lifeforms that survive this initial onslaught – [[Film/IndependenceDay and we're next]]. [[spoiler:[[https://hrodvitnon.tumblr.com/post/676003150839398400/ Word]] [[https://www.tumblr.com/hrodvitnon/703365355024859136/ of God]] also indicates that Ghidorah's new plan to [[PlanetaryCoreManipulation consume the Zohar at the Earth's core]] would most likely wipe out everything else on Earth in a ApocalypseHow/ClassX on the ApocalypseHow scale]]. This trope is even reflected in Ghidorah's TerribleTicking [[spoiler:which ultimately moulded Ghidorah's personalities into this trope in the first place; simplistically screaming at the backs of Ghidorah's heads, "'''KILL THEM ALL'''"]].
* OneManArmy: It's arguably this even amongst the Titans. Even when Ghidorah was being fought and overwhelmed by [[spoiler:''eight'']] other Titans including Godzilla (and when Ghidorah was in an incomplete state no less); it still put up quite a fight.
* OOCIsSeriousBusiness: [[spoiler:In Chapter 13, Vivienne is unnerved by how calm Ichi, Ni and San-2's voices are after she rips apart one of the Many's {{Mind Hive}}s]].
* ParentalAbandonment: San and his brothers originally came from a clutch of eggs, with no parents around to play a nurturing role. Vivienne believes this indicates the species Ghidorah originally hailed from would leave their eggs to fend for themselves, similar to sea turtles.
* PayEvilUntoEvil: [[https://www.fanfiction.net/s/13357907/10/ Chapter 10]] reveals that the first species-wide genocide Ghidorah committed billions of years ago was this. [[https://hrodvitnon.tumblr.com/post/645147573238333440/ Word of God]] also reveals that [[spoiler:Ghidorah originally tried to stick to committing this trope when it committed more genocides, before its SlowlySlippingIntoEvil]].
* PerpetualStorm: As revealed by San's memories and further confirmed by [[https://www.tumblr.com/hrodvitnon/703365355024859136/ Word of God]], Ghidorah's standard M.O. when conquering a planet includes covering the world in endless storms, which [[TheNightThatNeverEnds block out sunlight]] and radically reshape and beat down the terrains worldwide in order to break down the biosphere and prevent its regrowth. Ghidorah has successfully inflicted this fate on numerous alien worlds it previously destroyed, and it would've done the same to Earth during its reign of terror in the Mass Awakening if Godzilla hadn't killed it.
* PitifulWorms: It's called humans, including a brave Bone Singer who communicated with it long ago when it was frozen, "insects".
* PlanetaryCoreManipulation: [[spoiler:Keizer Ghidorah's new]] plan involves feasting on the [[NamedByTheAdaptation Zohar]] within the HollowEarth, with [[https://hrodvitnon.tumblr.com/post/676003150839398400/ Word of God]] suggesting this could [[ApocalypseHow/ClassX make the planet shatter like an egg]].
* PlanetDestroyer: Slightly downplayed in that from what we know, Ghidorah doesn't (usually) destroy the physical planets themselves, but it ''does'' wipe most to all of the biospheres; going to great lengths to thoroughly exterminate any species that rub it the wrong way, and often covering the planet's skies in a perpetual, global version of the hypercane that forms around Ghidorah on Earth and is liable to break down the biosphere. It's confirmed that Ghidorah has already turned a long line of alien worlds into barren trophies to its name over billions of years and numerous conquests, before Ghidorah's arrival on ancient Earth brought it into conflict with Godzilla.
* PosthumousCharacter: It's dead following the battle in Boston before the fic's main time frame [[spoiler:(at first)]], but its actions have caused San and Vivienne's transformation into Monster X, and it's hinted the severed head still has some of Ghidorah's minds in it. [[spoiler:Then Ichi, Ni and San-2 start regenerating [[FromASingleCell From a Single Head]]]].
* PostMortemComeback: It's responsible for Vivienne's death and her and San's rebirth as Monster X, and San's brothers feature through memories, flashbacks and dreams. [[spoiler:{{Subverted}} when Ghidorah has regenerated its minds, and their aforementioned dream appearance turns out to be RealAfterAll]].
* ThePowerOfHate: Ghidorah's "storm" powers are fuelled by hatred -- which Ichi, Ni and San are altogether wealthy in, unlike the two-headed Monster X who has more trouble drawing on such powerful negative feelings regularly.
* PragmaticVillainy: If you've read what it plans to do to Vivienne, then you'll know that Ghidorah [[spoiler:saving Monster X]] is ''not'' gonna be a good thing if Ghidorah gets its way with them immediately afterwards. There's also San-2/Youngest Brother [[spoiler:protesting to his brothers causing too much physical damage to Monster X more because he's concerned it'll irreparably break what San-2 sees as a beloved toy than out of humaneness]].
* [[PrecursorKillers Precursor Killer]]: [[spoiler:The alien AbusivePrecursors who turned Ichi, Ni and San into Ghidorah eons ago were among Ghidorah's first victims]].
* PsychicPowers: It exhibits a powerful psychic influence on humans around it which can have MindRape effects or worse, [[spoiler:in addition to its {{Psychic Link}}s with Monster X, the Many and implicitly one of the Zmeyevich broodmothers respectively]].
* PsychicLink: [[spoiler:Has one with Monster X, which it uses to try and BreakThemByTalking]]. It also has a psychic link with [[spoiler:the Many as their HiveQueen]], and it's hinted it might even have one with the Zmeyevich-carrying [[spoiler:Esfir]].
* PsychoactivePowers: It's revealed Ghidorah's electrical powers work this way, relying mainly on [[ThePowerOfHate hatred]].
* PutThemAllOutOfMyMisery: Ghidorah ''used'' to be this before it fully became an OmnicidalManiac. Before its [[SlowlySlippingIntoEvil epoch-spanning slip into becoming the evil monster we know it as]] was complete; it committed mass destruction again and again in an effort to [[spoiler:make [[TerribleTicking the Old Noise]] stop tormenting it]], and Ghidorah implicitly resorted to slaughtering lifeforms that were in no way to blame for [[spoiler:inflicting the Old Noise on it]] to that end.
* RasputinianDeath: And boy, is it epic. [[spoiler:Ghidorah's the target of a long CombinationAttack by ''eight'' Titans working together -- major points include Ni/Elder Brother's head suffering severe PalatePropping {{Jawbreaker}}, the lots of bone-breaking and being sliced open, and Ichi/Eldest Brother's gullet getting exploded open from the inside; before Ghidorah's body is vaporized. Ichi/Eldest Brother's decapitated head gets finished off by Monster X performing their own [[https://i.imgur.com/lAslwxJ.gif Kiss of Death]] which cleaves the head in two]]. The trope gets {{lampshaded}} by Lieutenant Commander Pasternak:
--> "''Make that Rasputin worm hurt!''"
* RedAndBlackAndEvilAllOver: The storm generated by [[spoiler:Keizer Ghidorah]] has red highlights as well as casting black shadows, unlike Ghidorah's storm in ''King of the Monsters''.
* RedBaron: Its titles mentioned during the story include the Devil, the Enemy, the Dragon, the Destroyer of Worlds, the One Who Is Many, That Which Came From The Stars, the Golden Demise, the Snake Father, the World Eater, the Song of Entropy, the Death Knell of Three Storms and the Great One.
* ReluctantPsycho: [[https://hrodvitnon.tumblr.com/post/645147573238333440/ According to the author]], Ghidorah was once this in the beginning. [[spoiler:Ghidorah's three brains had a single command forcibly hardwired into them through indicated alien brain surgery, which drove them to try again and again without success to make the TerribleTicking stop by sating it. The author suggests the command probably faded to something like tinnitus after eons, but by then, Ghidorah's SlowlySlippingIntoEvil had come full circle]]. What did the Terrible Ticking say?
--->'''Kill Them All.'''
* ReportsOfMyDeathWereGreatlyExaggerated: It's presumed by the world at large to be permanently dead, until Monarch find out about San's old head and Monster X confirms that Ghidorah will regenerate in the future.
* RevengeByProxy: Part of what made Ghidorah decide against pragmatically retreating at the [[spoiler:Berezniki]] battle was the idea of seeing the look on [[ArchEnemy Godzilla]]'s face if Ghidorah managed to kill Mothra and [[spoiler:use the Many to assimilate Thor]].
* RuleOfThree: [[spoiler:Ghidorah itself]] lampshades this trope in Chapter 16, noting Ghidorah has three heads and the number three is considered sacred among humans.
* {{Sadist}}: ''King of the Monsters'' already makes it clear that Ghidorah is an OmnicidalManiac with ForTheEvulz and ThereIsNoKillLikeOverkill tendencies, but this story goes more into showing how depraved Ghidorah (particularly Ichi/Eldest Brother) is capable of being when it wants to torment an individual ''without'' killing them, and also how [[spoiler:Ghidorah became that way]].
* SaltTheEarth: True to how San's memories reveal Ghidorah converts the atmospheres of the worlds it conquers into a [[PerpetualStorm global version of Ghidorah's hurricane]], [[https://hrodvitnon.tumblr.com/post/685085904520527872/ Word of God]] indicates Ghidorah will do everything in its power to make sure a conquered planet can never grow new complex life again before Ghidorah moves on.
* SatanicArchetype: Like in the movie. Vivienne always called it the Devil or the Dragon in her notes, it's often compared by human characters' narration to a devil, and [[spoiler:it serves as the [[WesternAnimation/TeenTitans2003 Trigon to Monster X's Raven]]]]. Like Satan, Ghidorah[[spoiler:'s descent into darkness began with it turning against its creators (similar to Satan's rebellion against God)]], and the EvilMakesYouUgly (see above) brings to mind Satan's transformation from a beautiful angel into a devil as a consequence of his crimes. The fates of humans who fall victim to Ghidorah's use of the Many, and [[spoiler:Ghidorah primarily residing in subterranean tunnels where its psychic influence is strong and it rules over the Many]], both bring to mind the idea of {{Hell}} with Satan ruling over its denizens and damned humans, while [[spoiler:Keizer Ghidorah assimilating the Many]] brings to mind a devil taking souls inside itself for power. Ghidorah's heads also [[spoiler:[[AsTheGoodBookSays quote the Serpent in the Book of Genesis]], specifically when the Serpent is tempting Eve]], and Ghidorah shows an aptly Satan-like level of hubris in how [[spoiler:the heads misinterpret or deliberately pervert the verse's meaning[[note]]Genesis 3:5 refers to how humans ''can't'' be like God, but Ghidorah uses the verse in reference to its plan to turn Vivienne into what Ghidorah views as a ''true'' god as well as in reference to her and the Many becoming enslaved to the Devil's (Ghidorah's) corruptive influence[[/note]]]]. It's hinted in Chapter 13 that [[{{Satan}} the Devil]] might literally be humanity's mythical memory of Ghidorah.
* SerpentOfImmortality: Ghidorah is TimeAbyss old, and it can never permanently die so long as a viable piece of its DNA remains.
* SickeningCrunch: An InUniverse case. During the [[spoiler:final]] battle with Godzilla, the latter ground his foot down on Ghidorah's back until he heard bones popping.
* SlowlySlippingIntoEvil: As described by the author [[https://hrodvitnon.tumblr.com/post/645147573238333440/ here]], Ghidorah gradually suffered this in its {{Backstory}} until it became the sadistic OmnicidalManiac we all know it as.
* SmugSuper: Ichi/Eldest Brother shows the ego part of this trope the most, but all three heads express a high opinion of Ghidorah in the BadassBoast -- it's not an understatement, as a ''badly weakened'' Ghidorah was capable of holding its own against '''seven''' Earth Titans [[spoiler:plus Monster X, and the ending heavily implies Ghidorah can still come BackFromTheDead again]]. [[https://hrodvitnon.tumblr.com/post/709885319486554112/ Word of God]] comments [[spoiler:and the penultimate chapter shows]] that Ichi is confident Ghidorah will always win in the end by virtue of it outlasting its enemies due to its resurrective immortality, [[spoiler:and he has the age and past experience from Ghidorah's galactic conquests to back this up]].
* SpaceNomads: Before arriving on Earth, it's been moving from world to world, conquering each one and then moving on.
* SpeakIllOfTheDead: All three heads have done this at some point or another. All of them speak lowly of [[spoiler:Jonah]] shortly after he's killed, and Ni/Elder Brother called Thor's kind whom Ghidorah exterminated "misbegotten" after the act.
* SpectacularSpinning: [[spoiler:Keizer Ghidorah]] spins gracefully whilst performing {{Tail Slap}}s against its Titan foes in Chapter 17.
* {{Sssssnaketalk}}: Only when the three heads all say this word in unison:
-->"'''''YESSSS'''[=SSSSssssss=]''"
* StalkerWithoutACrush: It psychically haunted Vivienne for years when she was monitoring Outpost 32. [[spoiler:Ichi/Eldest Brother, Ni/Elder Brother and San's EvilDoppelganger are stalking Vivienne and San even more viciously after Monster X's creation]]. This trope is nightmarishly ZigZagged [[spoiler:when Ghidorah, including a particularly InLoveWithYourCarnage Ni/Elder Brother, plans to forcibly use Vivienne as a monster BabyFactory whilst torturing her]].
* StrawHypocrite: [[https://hrodvitnon.tumblr.com/post/677379767724621824/ Word of God]] comments that [[spoiler:Ghidorah basically exploits the Many's deification of it to manipulate them]].
* StrawNihilist: It has shades of this, viewing all other life as temporary and worthless, and believing that nothing besides Ghidorah has any real value because Ghidorah is the only thing which lasts forever. According to [[https://hrodvitnon.tumblr.com/post/645147573238333440/ the author]], it's rooted in Ghidorah's own realization during its SlowlySlippingIntoEvil that there ''was'' no reason why [[spoiler:it was the victim of such tragedy, and that asking what the point of its ReluctantPsycho programming was]] was equally pointless.
--->'''San-2:''' ''we tried at first tried to find meaning in their screams tried to find meaning in yours there was nothing to find [...] that is the meaning we found it is nothing there is no meaning we conquered we hunted we killed every world was mindless the [[spoiler:ones who made us]] screamed when we killed them nothing left all gone lives wasted honors meaningless''
* SuperEmpowering: There's what San did to Vivienne when he transformed her body into an ArtificialHybrid by feeding his Ghidorah biology's enzymes into her inside his neck's "womb". Plus, [[spoiler:[[TranshumanAbomination the Many]] are a lot more durable and deadly than when they were autonomous living creatures]].
* TailSlap: Ghidorah's twin tails make for useful whipping and clubbing weapons against other Titans.
* TalkativeLoon: It's rather jarring reading Ghidorah's three minds talking over each-other at the same thing.
* TelepathicSpacemen: Ghidorah is an extraterrestrial Titan with outright telepathic capabilities, [[spoiler:such as its PsychicLink to its creations]]; a trait that this story introduced to Ghidorah long before ''Godzilla vs. Kong'' explicitly revealed the [=MonsterVerse=] canon version of Ghidorah was telepathic.
* TerribleTicking: A nasty variant. As [[https://hrodvitnon.tumblr.com/post/645147573238333440/ revealed by the author]], an alien noise which Ghidorah calls "the Old Noise" [[spoiler:was deliberately programmed by Ghidorah's creators into it]] and exists in its three minds: [[https://hrodvitnon.tumblr.com/post/666120662644080640/ The]] [[https://hrodvitnon.tumblr.com/post/691602917794414592/ author]] further described it as an aggressive, mentally-horrible sound, comparing it to a superheated ice pick being shoved into one's brain. The aggravating noise itself has an underlying clear message [[spoiler:programmed by the Makers]] which Ghidorah's heads are fully aware of: '''"Kill Them All"'''. It's actually the Old Noise that drove Ghidorah to repeatedly commit genocide at first in its backstory. The author thinks the Noise has faded to something like tinnitus after billions of years, but it had long since [[SlowlySlippingIntoEvil fully extracted its toll on Ghidorah's minds]] by that time.
* ThereIsNoKillLikeOverkill: Naturally, the Titans have to employ this on Ghidorah whenever they kill it, trying to kill every last bit of it present in the hopes there'll be nothing for it to resurrect from and that there won't be another next time.
* TheseAreThingsManWasNotMeantToKnow: Ghidorah is this trope made flesh, since a decapitated head alone produces a BrownNote effect on humans who spend too much time around it, and experimentation on Ghidorah's tissue ends up creating the Many.
* TimeAbyss: The author [[https://hrodvitnon.tumblr.com/post/637986068089716737/ stated]] Ghidorah is eons old.
* TorturedMonster: [[https://hrodvitnon.tumblr.com/post/645147573238333440/ Word of God]] reveals that Ghidorah ''began'' as this billions of years ago with its TerribleTicking, but SlowlySlippingIntoEvil eventually turned it completely gleefully evil.
* TurnedAgainstTheirMasters: [[spoiler:It's heavily implied Ghidorah was created and made AxCrazy to be a BioweaponBeast. Unfortunately for Ghidorah's alien creators, Ghidorah turned on them and killed them all whilst doing exactly what they'd wanted it to]].
* [[TwoBeingsOneBody Three Beings, One Body]]: It's heavily implied in Chapter 10 that [[spoiler:Ichi, Ni and San were originally three single-headed creatures, and the brothers were turned into the three-headed destroyer by alien experiments]].
* VampiricDraining: Like in [=MonsterVerse=] canon. San notes Ghidorah uses the ability to strengthen itself while draining its enemies' LifeEnergy, and it's revealed Ghidorah inflicted this on [[spoiler:Thor's son]].
* VengeanceFeelsEmpty: PlayedWith. [[spoiler:It apparently reacted this way to killing the alien beings who'd created and tortured it, albeit mainly because their deaths didn't quell the noise they'd programmed into Ghidorah's heads]].
* VillainousIncest: It's revealed in Chapter 16 that [[spoiler:Ghidorah intends to make Monster X a BabyFactory, despite its heads admitting that they consider Vivienne their [[BrotherSisterIncest sister]] ''and'' their [[ParentalIncest daughter]]]].
* VillainsNeverLie: Ghidorah literally lacks a concept of lying or dishonesty, though that's not to say it's incapable of psychological manipulation.
* VillainTakesAnInterest: [[spoiler:It's pleased by Vivienne's capacity for UnstoppableRage as Monster X in Chapter 13 and plans to "teach" her to be just as bad as Ghidorah is. Ni/Elder Brother in particular becomes more interested in taking an active role in his brothers' plans for Vivienne after this]].
* VoicesAreMental: PlayedWith. When communicating with those who can understand [[AnimalTalk Kaiju Talk]], Ghidorah's three heads each have a distinct-sounding voice from each-other.
* WalkingSpoiler: Take a look at the rest of this folder.
* WoobieDestroyerOfWorlds: Make no mistake, Ghidorah is every bit as vile, psychopathic, genocidal and sadistic as in [=MonsterVerse=] canon or in ''any'' ''Godzilla'' licensed canon, but it has a pretty valid reason for being as broken and monstrous as it is. [[spoiler:As described in Chapter 10 and [[https://hrodvitnon.tumblr.com/post/645147573238333440/ further elaborated on by the author]]; Ichi, Ni and San were originally just three critters in an alien ecosystem fighting together to survive, before they were captured, forcibly transformed into Ghidorah and [[BeingTorturedMakesYouEvil methodically tortured]]. Ghidorah exterminated its tormentors in a combination of revenge and desperation to satiate the TerribleTicking they'd programmed into the three heads, but this failed to bring Ghidorah any peace or satisfaction. Ghidorah inflicted mass destruction again and again trying to make the Ticking stop, and SlowlySlippingIntoEvil gradually destroyed what goodness Ichi/Eldest Brother and Ni/Elder Brother still had in them until they became the monstrously cruel OmnicidalManiac we all know Ghidorah as]].
* YankTheDogsChain: [[spoiler:In Chapter 12, its psychic attacks on Monster X seem to lull, then it takes advantage to attack Vivienne ferociously when she's most vulnerable during her reunion with her mother]].

!! Tropes applying to the heads individually

* AffablyEvil: San-2/Youngest Brother is arguably the ZigZagged form. He's just as brutal as the other two heads in battle or when you're just in Ghidorah's way, and he views other living things which aren't a direct part of him as mere tools and toys, but he's the type of PsychopathicManchild who prefers playing ''lovingly'' with his toys and hates it when they get broken. [[https://hrodvitnon.tumblr.com/post/677379767724621824/ Word of God]] even comments that he tolerates the Many partly because he thinks Ghidorah can "fix" them.
* AlternateSelf:
** San-2/Youngest Brother, who is the result of San's original head following his mind transfer to the hybridized Vivienne re-forming San's pre-transfer personality and memories whilst it regenerated the rest of Ghidorah. As a result, San-2 lacks San's CharacterDevelopment that led to his HeelFaceTurn. Vivienne is able to tell the two San's apart when the evil one speaks to her in [[https://www.fanfiction.net/s/13357907/11 Chapter 11]], as San-2's voice sounds the same as when San first fused to her.
** There's also [=MaNi=]/Elder Brother. See his folder for details.
* AndIMustScream: Being frozen in the glacier and aware of the humans building a "cage" around it was this fate for Ichi/Eldest Brother in particular, and to a lesser extent Ni/Elder Brother. Whereas San could at least take some satisfaction in curiously watching the humans around them, the other two heads were pissed off and Ichi's BerserkButton was ''utterly'' pressed, yet they couldn't do a damn thing except mentally froth in rage and loathing until Ghidorah was freed from the glacier. [[https://hrodvitnon.tumblr.com/post/688985016945000448/ Word of God]] also makes it clear that [[spoiler:Vivienne becoming the immortal DraconicAbomination[='s=] fourth head]] would have very much been this trope thanks to Ichi/Eldest Brother and Ni/Elder Brother's cruelty and capabilities.
* AsTheGoodBookSays: [[spoiler:Ni/Elder Brother and San-Who-Could-Have-Been/Youngest Brother at one point paraphrase Genesis 3:5, when referring to Ghidorah's plan to corrupt and then assimilate Vivienne]].
* AsYouKnow: San-2/Youngest Brother provides a little exposition while observing [[spoiler:the partly-regenerated Ghidorah]]'s situation aloud, which annoys [[spoiler:Ichi/Eldest Brother]], in Chapter 17.
* AttackTheMouth: [[spoiler:In Chapter 17, Monster X destroys Ichi/Eldest Brother's head by firing their [[EyeBeams Destroyed Thunder]] into his mouth]].
* BaddieFlattery: San-Who-Could-Have-Been/Youngest Brother [[spoiler:and also Ichi/Eldest Brother]] compliment Monster X (specifically Vivienne) a couple times on how strong and ferocious a creature she's grown into, [[spoiler:and on her impressive performance against Keizer Ghidorah]].
* BeingEvilSucks: San-2/Youngest Brother suffers this exactly like San did; getting no love and only the scarcest respect from his abusive brothers and being more interested in having a new sister than [[OmnicidalManiac Omnicidal Mania]].
* BerserkButton: Ichi/Eldest Brother specifically was ticked off by humans (namely Vivienne) building a "cage" around Ghidorah while it was frozen. It's also revealed that Ghidorah has such an extreme reaction to hearing an ORCA signal because it [[spoiler:brings back bad memories from Ghidorah's {{Backstory}} as a TorturedMonster]]. It's heavily implied in the story, and confirmed by [[https://hrodvitnon.tumblr.com/post/677549009646272512/ Word of God]], that Ghidorah goes into KillAllHumans mode when it encounters humans and has actively obliterated similar civilizations on other worlds purely because Ichi and Ni (Ichi especially) despise any reminder of [[spoiler:the human-like AbusivePrecursors who tortured them]].
* BigBrotherBully: Ichi and Ni towards San. They didn't show him a shred of affection nor allow him to indulge in anything that didn't involve eating and killing; roaring in his ears and biting at his horns when they disapproved of his curious tendencies. Ichi is also willing to get equally physical with Ni when the middle sibling tests his boundaries, as shown [[https://hrodvitnon.tumblr.com/post/709885319486554112/ here]].
* BigShutUp: Both Ichi/Eldest Brother and Ni/Elder Brother snapped at San[[spoiler:-2/Youngest Brother]] with this for doing little more than raising his voice.
* BloodKnight: Ni/Elder Brother particularly enjoys fighting and killing for their own sakes more than the other two heads do, relishing in the heat of an intense fight (although he's still somewhat more restrained than [=MaNi=]) . [[https://hrodvitnon.tumblr.com/post/709885319486554112/ The author]] compares Ni to a combat adrenaline junkie, and it's furthermore revealed Ni was more irate than gleeful when the Oxygen Destroyer cut Godzilla and Ghidorah's battle unceremoniously short, not caring that Ghidorah was seriously losing that battle before the O.D. hit.
* BrutalHonesty: [[https://hrodvitnon.tumblr.com/post/697040294509690881/ Word of God]] comments that Ni/Elder Brother is "too direct and in-your-face" to care about trying to lie or even use {{exact words}} if he were to gain an understanding of the concept of lying ([[spoiler:(which he does)]]. It can also be safely presumed that San-2/Youngest Brother would have the same derision for dishonesty as [[Characters/AbraxasHrodvitnonMonsterX San]] does.
* CainAndAbel: Ichi/Eldest Brother and Ni/Elder Brother are the Cain to San's Abel.
* CardCarryingVillain: Ichi/Eldest Brother and Ni/Elder Brother are proud of their omnicidal history, as the BadassBoast demonstrates.
* CowardiceCallout: Ichi/Eldest Brother and Ni/Elder Brother expressed disdain for Thor to his face over his decision to flee into hibernation for his life instead of fighting to the death against Ghidorah like the rest of his kin.
* CruelMercy: ZigZagged. Ichi/Eldest Brother originally ordered San to bring Vivienne BackFromTheDead transformed into a part-Ghidorah monster as a way to torment her, never mind what Ichi probably would've done to her afterwards if Ghidorah had never been killed at Boston.
* DeadpanSnarker: Ichi/Eldest Brother and Ni/Elder Brother have moments, particularly during [[spoiler:the VillainousBreakdown[='s=] early stages]]. [[https://hrodvitnon.tumblr.com/post/656909793179631616/ Word of God]] confirms these two inhuman minds picked it up by [[spoiler:gaining mental access to the Many's victims' socio-cultural knowledge]].
---> '''[[spoiler:San-2]]:''' [[spoiler:brothers]] there is a problem\\
'''Ichi: THERE IS ALWAYS A PROBLEM WHAT NOW'''\\
[…]\\
'''Ni:''' WHAT A NUISANCE I'VE ONLY JUST [[HydraProblem COME BACK]]
* DefiantToTheEnd: Ichi/Eldest Brother after his head was ripped off and he was forced to watch the rest of Ghidorah get destroyed, [[spoiler:in Chapter 17]]. However, he did [[spoiler:freak out at the very end, partly due to a little BreakThemByTalking from Monster X]].
* DisproportionateRetribution: Ichi/Eldest Brother wanted to grant Vivienne a FateWorseThanDeath purely because she unwittingly hit his BerserkButton hard by leading humans in building a "cage" around the glacier Ghidorah was frozen inside.
* TheDogBitesBack: {{Downplayed}}. [[spoiler:San-2/Youngest Brother doesn't hesitate to snap at, bite and threaten to kill [=MaNi=]/Elder Brother without consequences, since said version of Ni is no longer considered part of Ghidorah]].
* DoppelgangerGetsSameSentiment: {{Averted}} hard by Vivienne in regard to San-2/Youngest Brother, as she has no interest in fulfilling this trope nor the implications of doing so. [[spoiler:However, during the FinalBattle, Monster X recognizes San-2 as indeed being "San-Who-Could-Have-Been" and mourns his RedemptionEqualsDeath HeroicSacrifice]].
* EarAche: San-2/Youngest Brother, like San before him, gets bitten by [[spoiler:Ichi/Eldest Brother]] and harshly dragged around by his horns a lot.
* EvilCounterpart: Monster X overall is a GoodCounterpart to Ghidorah, but Vivienne has an Evil Counterpart in Ichi/Eldest Brother. He's essentially what Vivienne could've become if she completely snapped and gave in to rage and madness during her TraumaCongaLine, and if she became hateful, lost her positive character traits and abused San just as Ichi abuses his Youngest Brother. [[https://hrodvitnon.tumblr.com/post/680115466430283776/ Word of God]] even states Ichi/Eldest Brother used to be much like Vivienne before his corruption. Interestingly, they both have a degree of ParentalAbandonment with their biological parents, but whereas Vivienne found a ParentalSubstitute, Ichi had to ''[[PromotionToParent be]]'' [[PromotionToParent a Parental Substitute]]. Vivienne has people she loves like family or outright adoptive family (Serizawa, Madison and San), whereas Ichi as far as we know never had anyone other than his brothers.
* EvilDoppelganger: The version of San who replaces the San that fused with Vivienne. San-2 has no apparent compunctions against using BreakThemByTalking and MindRape on San and Vivienne.
* EvilFeelsGood: Ni/Elder Brother and especially Ichi/Eldest Brother appear to be of this opinion.
* EvilHasABadSenseOfHumor: Ichi/Eldest Brother displays the Sick Sense of Humor. His response to a Titan he wanted captured alive seeking to flee his presence was to say the Titan could go free, then have his brother break said Titan's legs so it couldn't do more than squirm in pain on the ground in an immobile state. [[https://hrodvitnon.tumblr.com/post/677549009646272512/ Word of God]] also says that Ichi/Eldest Brother and Ni/Elder Brother find the dark side of humanity outright amusing.
* EvilMentor: San-2/Youngest Brother in particular shows an interest in being this to Vivienne.
* EvilSoundsDeep: The mental voices of Ichi/Eldest Brother in particular, and also San-2/Youngest Brother -- see ComicBookFantasyCasting.
* EvilSoundsRaspy / GutturalGrowler: The voice of Ni/Elder Brother (see ComicBookFantasyCasting).
* ExactWords: It's hinted in the story and confirmed by [[https://hrodvitnon.tumblr.com/post/697040294509690881/ Word of God]] that Ichi/Eldest Brother (unlike his brothers) would be all too happy to use this trope as a way to manipulate or toy with others in order to get what he desires, if Ghidorah were to wrap its heads around the concept of lying. [[spoiler:Which it does, with Ichi manipulating the Many into believing they are PiecesOfGod]].
* EyeScream: In Chapter 17, [[spoiler:both Ni/Elder Brother and Ichi/Eldest Brother lose an eye to Monster X and Mothra respectively]].
* FauxAffablyEvil: [[spoiler:Ichi/Eldest Brother has started displaying this kind of attitude in Chapter 14. According to [[https://hrodvitnon.tumblr.com/post/639403196006203392/ the author]], he's mainly using it as a psychological warfare tactic against Vivienne]].
* FeedItABomb: [[spoiler:During the FinalBattle, Godzilla holds the middle head's jaws open whilst the military drops a GBU-57 which lands down the head's gullet and explodes there]]. For the record, the GBU-57 is called a "bunker buster" bomb in RealLife.
* GoOutWithASmile: [[spoiler:San-2/Youngest Brother reacts with a genuine smile to Vivienne referring to him as her brother, before he resumes his HeroicSacrifice]].
* GrinOfAudacity: Ichi/Eldest Brother sported such a grin when [[spoiler:Ghidorah is surrounded by multiple Titan foes before fighting back]].
* HeelRealization: [[https://hrodvitnon.tumblr.com/post/656909793179631616/ Word of God]] confirms that [[spoiler:San-2/Youngest Brother experienced one parallel to the main San's earlier one, as a result of reading Thor's memories]].
* HeManWomanHater: Ni/Elder Brother picked up a nasty case, [[spoiler:due to a combination of learning humanity's socio-cultural knowledge and his "murder boner" towards Monster X]].
* HeroicSacrifice: [[spoiler:In Chapter 17, San-2/Youngest Brother has a RedemptionEqualsDeath; using his final minutes to attack his evil brother heads with his jaws and aid the other Titans, before Ghidorah is cooked to nothing once more]].
* HumanityIsInfectious: Very much {{downplayed}}. [[https://hrodvitnon.tumblr.com/post/656909793179631616/ Word of God]] confirms that [[spoiler:Ichi/Eldest Brother and Ni/Elder Brother]]'s DeadpanSnarker moments and [[spoiler:the latter's HeManWomanHater]] mouth are the result of exposure to the Many's human socio-cultural knowledge stores, but that's about where humanity's influence on them ends.
* {{Hypocrite}}: Ichi/Eldest Brother once insisted that death is the end of all things, and shortly thereafter he boasted alongside his brothers that Ghidorah is deathless and eternal. An ancient Bone Singer called Ghidorah out on this. See above for another example.
* IJustWantToBeLoved: San-2/Youngest Brother has the same unfulfilled craving for affection as San did, being a clone of the latter San as his personality was before his CharacterDevelopment.
* InLoveWithYourCarnage: [[spoiler:Both Ichi/Eldest Brother and Ni/Elder Brother react this way towards Vivienne after witnessing Monster X's capacity for savagery. They subsequently want to mentally destroy Vivienne until this violent streak becomes the entire definition of her personality, with [[https://hrodvitnon.tumblr.com/post/677549009646272512 Word of God]] noting Ni in particular is interested in the [[RapeIsASpecialKindOfEvil raping]] part]].
* InSeriesNickname: In {{canon}}, Ghidorah's heads were only named Ichi, Ni and San as a ProductionNickname and were never called this InUniverse. In this fic, it's revealed in [[https://www.fanfiction.net/s/13357907/2 Chapter 2]] that Vivienne gave the heads their names while she was monitoring Outpost 32. Ichi and Ni seemingly don't answer to these names, and they're referred to by San as Eldest Brother and Elder Brother respectively. San-2/Youngest Brother eventually earns the name San-Who-Could-Have-Been from Monster X.
* ItsPersonal: Apart from how Ghidorah is on the receiving end of this from a ''lot'' of characters; Ichi/Eldest Brother eating Vivienne alive and wanting San to grant her a FateWorseThanDeath was done because she hit his BerserkButton.
* {{Jawbreaker}}: In Chapter 17, [[spoiler:Ni/Elder Brother inflicts this on himself when his head is impaled on Methuselah's horn, pulling himself free but ripping half his jawbone away]].
* LaserGuidedKarma: [[spoiler:Ichi/Eldest Brother gets a couple doses of this in Chapter 17. He's the head who ate Vivienne alive, and he's [[FeedItABomb force-fed a bomb which blows up in his neck]]. After he spent so much time viciously getting into Viv and San's heads trying to inflict BreakThemByTalking, they get to turn the tables on him before his KarmicDeath]].
* LosingYourHead: [[spoiler:Ichi/Eldest Brother's head gets ripped off, and he remains conscious and animate until he's executed]], in Chapter 17. {{Justified}}, as [[https://hrodvitnon.tumblr.com/post/689311522082668544/ Word o]][[https://hrodvitnon.tumblr.com/post/689317106053955584/ f God]] reveals Ghidorah's heads rely on internal power reserves to remain animate after being decapitated.
* MeaningfulLook: San-2/Youngest Brother during [[spoiler:his RedemptionEqualsDeath]] makes it clear just by giving Monster X a look that [[spoiler:Thor is almost done for]].
* MirrorCharacter: It turns out both Alan Jonah and Ichi/Eldest Brother [[spoiler:despise humans/"little ones" due to the latter's involvement in the traumatic events that shaped either character into the villains they now are]]. They also both had [[BeingTorturedMakesYouEvil similar intentions]] for Monster X (particularly the creature's Vivienne half). Jonah and Ichi/Eldest Brother are both older than most characters in their class (Jonah is EvilOldFolks, Ghidorah is TheOlderImmortal) as well. One has to wonder if [[spoiler:Ghidorah]] used these parallels to manipulate Jonah during [[spoiler:his SanitySlippage]].
* NoRangeLikePointBlankRange: Ichi/Eldest Brother at one point is shown unsuccessfully attempting to fire a Gravity Beam into Godzilla's face at close range.
* NotSoDifferentRemark: [[spoiler:Ichi/Eldest Brother]] says as much about Vivienne when conversing with Monster X, twice. The first time leads to a NotSoSimilar speech from her.
* ObliviouslyEvil: ZigZagged by San-2/Youngest Brother. He hates himself and he's under no illusions about how vicious and barbaric his brothers are, but he genuinely doesn't seem to understand how turning Vivienne into a monster or forcibly [[spoiler:inducting her into Keizer Ghidorah's BigScrewedUpFamily]] is anything other than helping her, [[spoiler:until he gets some TalkingTheMonsterToDeath]].
* OhCrap: Being confronted with the idea that Ghidorah's enemies might actually be able to hunt down all the pieces of it and thereby make his impending death become permanent was enough to make Ichi/Eldest Brother's eyes fractionally widen, despite his efforts to save face, [[spoiler:in Chapter 17]].
* TheOnlyOneAllowedToDefeatYou: According to [[https://hrodvitnon.tumblr.com/post/709885319486554112/ this snippet]] by the author, Ni/Elder Brother hoped during the movie's events that Godzilla survived the Oxygen Destroyer's impact when he disappeared, solely because Ni wants Ghidorah to be the thing which fells Godzilla.
* PalatePropping: [[spoiler:Somewhat {{inverted}}. During the FinalBattle, Ni/Elder Brother's jaws get jammed shut by Methuselah's horn getting stabbed upward through his jaw and skull]].
* PetTheDog: San-2/Youngest Brother, like the real San before the latter's CharacterDevelopment, regards Vivienne the way a child would regard their favorite toy, and he [[spoiler:ferociously intervenes when [=MaNi=]/Elder Brother causes too much damage to Monster X. San-2 at one point fleetingly attempts to {{exploit}} this trope when telepathically contacting Vivienne]].
* PoliticallyIncorrectVillain: Downplayed with Ni/Elder Brother, but he seemed to enjoy talking about females fucking or negatively comparing San[[spoiler:-Who-Could-Have-Been/Youngest Brother]]'s complaints to "A BITCH IN HEAT" after he [[spoiler:has assimilated humanity's socio-cultural knowledge]].
* PretenderDiss: [[spoiler:Both Ichi/Eldest Brother and San-Who-Could-Have-Been/Youngest Brother]] scorn [=MaNi=]/Elder Brother for claiming he's still part of Ghidorah.
* PromotionToParent: San mentions in Chapter 10 that Ichi/Eldest Brother had to rear the other two brothers himself due to their ParentalAbandonment, early in the trio's backstory.
* PsychologicalProjection: [[https://hrodvitnon.tumblr.com/post/684182475131551744/ Word of God]] notes San-2/Youngest Brother does an entirely {{justified}}, doppelgänger-on-doppelgänger form when he [[spoiler:joins Ichi/Eldest Brother and [=MaNi=]/Elder Brother and]] gives San TheReasonYouSuckSpeech on his shortcomings.
* PsychopathicManchild: San-2/Youngest Brother, just like San was before his CharacterDevelopment. He initially reacts like a petulant child when he and [[spoiler:his brothers]] aren't getting their own way with Vivienne in Chapter 17.
* RealAfterAll: {{Implied}} with [[spoiler:Ichi/Eldest Brother and Ni/Elder Brother]]. In Chapter 5, San hears [[spoiler:his brothers' voices beating him down when he has his HeelRealization]]. Since [[spoiler:all three of Ghidorah's heads have regenerated enough to be conscious]] a few chapters later, it's possible that what San heard [[spoiler:was the real Ichi and Ni rather than a guilt-fueled hallucination]].
* TheReasonYouSuckSpeech: When Monster X is [[spoiler:experiencing face-to-face torment from Ghidorah]] and thus re-encountering the supposedly-dead hydra's middle head alongside San-2/Youngest Brother, San gives the two heads an epic one in retort to the one he's received; in [[https://www.fanfiction.net/s/13357907/16/ Chapter 16]]:
--->"''AND WHAT ABOUT YOU?! [[AlternateSelf YOU]] '''[[AlternateSelf ARE]]''' [[AlternateSelf ME]]! CHANGING [Vivienne] WAS MY TASK! BUT I CHOSE TO STAY WITH HER! WHERE WERE YOU WHEN THE TORMENT BEGAN?! WHERE WERE '''YOU''' TO TEACH HER CONTROL?! YOU WERE PLAYING AT [[spoiler:BEING [[AbusivePrecursors MAKERS]]]]!''"
* RedemptionEqualsDeath: [[spoiler:After some TalkingTheMonsterToDeath and [[https://hrodvitnon.tumblr.com/post/656909793179631616/ viewing Thor's memories]], San-2/Youngest Brother ultimately turns on his evil brothers, helping Monster X and the benevolent Titans to destroy Ghidorah including himself]].
* RestrainingBolt: [[https://hrodvitnon.tumblr.com/post/656909793179631616/ The author]] has described Ichi/Eldest Brother as being this to the other two heads, keeping the left head's TokenGoodTeammate curiosity and the right head's otherwise StupidEvil-inducing psychotic desires (which manifest unrestrained in [=MaNi=]) in check.
* SlasherSmile: Ichi/Eldest Brother just smiles confidently when [[spoiler:Vivienne declares they're NotSoSimilar in [[https://www.fanfiction.net/s/13357907/14/ Chapter 14]], and he also pulls a smirk in the style of the Antarctica scene in the face of the Titans' war cry in Chapter 17]]. It gets lampshaded that Ichi is the head who sports this expression the most prominently out of the three.
* TheSociopath: Ichi/Eldest Brother and Ni/Elder Brother. LackOfEmpathy and Devoid of Conscience? ''Oh, definitely yes''. They're not {{Consummate Liar}}s solely because they CannotTellALie (see VillainsNeverLie), but they're quite knowledgeable on exploiting what psychologically makes their victims tick when they need to. They have a Pathological Need for Stimulation specifically in the form of sadistically killing everything and anything they can. They have a Shallow Effect in how they have no emotional attachment towards each-other, their Youngest Brother nor anything else. And they definitely have a Grandiose Sense of Self-Importance as the BadassBoast, combined with the fact they consider themselves the only true god compared to Earth's Titans, demonstrate.
* TakingYouWithMe: San-Who-Could-Have-Been/Youngest Brother [[spoiler:and Thor]] pull one on [[spoiler:Keizer Ghidorah, fighting with Ichi/Eldest Brother and Ni/Elder Brother until Ni, San-Who-Could-Have-Been and Thor are all vaporized together]] in Chapter 17.
* TalkingTheMonsterToDeath: [[spoiler:San-2/Youngest Brother is on the receiving end from San and Vivienne when psychically conversing with them in Chapter 17. This is part of what leads to him pulling a RedemptionEqualsDeath]].
* TeethFlying: [[spoiler:In Chapter 17]], Godzilla forces Ichi/Eldest Brother's jaws shut so violently that this happens.
* TermsOfEndangerment: Ichi/Eldest Brother and Ni/Elder Brother calling Vivienne "Bone Singer" is somewhat this, [[https://archiveofourown.org/comments/246407908 according to the author]].
* ThirdPersonPerson: San-Who-Could-Have-Been/Youngest Brother exclusively refers to himself as "this one" or doesn't use first-person pronouns at all, the same as San before his CharacterDevelopment.
* ThisCannotBe: [[spoiler:Ichi/Eldest Brother ends up reacting with denial before Monster X cooks his head to nothing]] in Chapter 17.
* TokenGoodTeammate: Like San before he fused with Vivienne, San-2/Youngest Brother is the least vicious of the three heads but still not devoid of sadism, and he hates it when his brothers [[spoiler:damage their "toy" too much]].
* TragicVillain: Besides Ghidorah's WoobieDestroyerOfWorlds backstory; both [[https://hrodvitnon.tumblr.com/post/640060179124305920/ the author]] and a reviewer have also noted that it's actually quite tragic that San-2/Youngest Brother has the same potential for a HeelFaceTurn as Vivienne's San does but him remaining attached to his brothers limits that from happening. Think Nebula in ''Film/AvengersEndgame''...
* TrashTalk: PlayedWith. Both Ichi/Eldest Brother and Ni/Elder Brother viciously taunted Thor ''before'' a fight, [[spoiler:leading Thor in turn to try provoking Ghidorah into accepting his challenge, in Chapter 17]].
* TwoFaced: [[spoiler:During the FinalBattle, half of Ni/Elder Brother's head gets reduced to a crater on one side]].
* UsedToBeASweetKid: Apparently, Ichi/Eldest Brother used to be a genuinely nurturing older brother and a protective creature, before [[spoiler:the Makers and the Old Noise]] got to him, with the [[https://hrodvitnon.tumblr.com/post/680115466430283776/ author's]] [[https://hrodvitnon.tumblr.com/post/709885319486554112/ posts]] further indicating he used to be much like [[NiceGirl Vivienne]].
* VillainousBreakdown: [[spoiler:Ichi/Eldest Brother and Ni/Elder Brother have a gradual one over the course of Chapter 17. They get more and more frustrated with all the Titans' opposition and Ghidorah's increasing disadvantage, and they're caught off-guard when San-2/Youngest Brother [[RedemptionEqualsDeath turns on them]]. When Ichi's head is all that's left of Ghidorah, he's proverbially shitting his pants when Monster X is about to execute him]].
* VillainousBSOD: In Chapter 17, San-2/Youngest Brother seems to be in one whilst he's [[spoiler:viewing Thor's loving memories of the family he lost]].
* VillainRespect: Ichi/Eldest Brother has a moment of this [[spoiler:when his decapitated head (confident he and his brothers will still come back eventually) compliments Monster X after the destruction of Keizer Ghidorah's body]].
* VirtueIsWeakness: [[https://hrodvitnon.tumblr.com/post/677549009646272512/ Word of God]] notes that Ni/Elder Brother in particular associates goodness with weakness and considers it unacceptable.
* WeWillMeetAgain: [[spoiler:Ichi/Eldest Brother]] tells [[spoiler:Monster X]] during [[spoiler:Keizer Ghidorah's destruction]] that they will be back.
* WhenHeSmiles: San-2/Youngest Brother gives Monster X a sad smile just like San's after he [[spoiler:turns on his brother heads]] in Chapter 17.
* WhiteSheep: {{Downplayed}} by San-2/Youngest Brother due to having the same personality as San before his CharacterDevelopment, expressing disapproval at [=MaNi=]/Elder Brother for going too far [[spoiler:and almost killing Vivienne. PlayedStraight when San-2/San-Who-Could-Have-Been betrays his brothers]].
* YouAreACreditToYourRace: {{Inverted}} by Ichi/Eldest Brother and Ni/Elder Brother; they told Thor to the latter's face that he was even lowlier than the rest of his "misbegotten kind" (Ni's words) for fleeing Ghidorah's genocide instead of fighting back.
* YouFool: Ni/Elder Brother snarled "FOOLISH" in response to Vivienne daring to get close to the glacier holding Ghidorah despite her fear of it, not that she could directly hear him. Ichi/Eldest Brother derided [[spoiler:Jonah]] as "'''THE OLD FOOL'''" for his hubris, and he also labelled [[spoiler:[=MaNi=]/Elder Brother]] foolish for his StupidEvil nearly compromising Ghidorah's plans.
* YouRemindMeOfX: Slightly downplayed, twice.
** Part of the reason why Ichi/Eldest Brother hated Vivienne as much as he did was because her building a "cage" around Ghidorah reminded him of creatures from his past that he ''really'' hates: [[spoiler:Ghidorah's Makers]]. [[https://hrodvitnon.tumblr.com/post/677549009646272512/ Word]] [[https://hrodvitnon.tumblr.com/post/709985632633634816/ of God]] suggests that Ni/Elder Brother initially has a more adverse hatred of Vivienne than Ichi's obsessive hatred because Vivienne actually reminds Ni of ''Ichi'', [[spoiler:back when the latter [[VirtueIsWeakness still had goodness in him]]]].
** [[https://hrodvitnon.tumblr.com/post/677549009646272512/ Word of God]] confirms the implications that Ichi/Eldest Brother's and possibly Ni/Elder Brother's genocidal hatred of humans stems from humans (and many other alien little ones that Ghidorah exterminated) reminding Ichi and Ni of something from their past – [[spoiler:the Makers. [[https://hrodvitnon.tumblr.com/post/690309147799011328/ Word of God]] has even suggested that some of the civilizations Ghidorah exterminated in its past were [[ButWhatAboutTheAstronauts off-world remnants of the Makers' species]]]].
** Part of the reason why Ichi/Eldest Brother and Ni/Elder Brother came up with a specific [[spoiler:{{villainous incest}}uous]] part of their plan for Vivienne? It's because they came to see themselves in her in more ways than one, [[spoiler: and they're ''aroused'' by the violence she's capable of after becoming part of Monster X]].
[[/folder]]

[[folder:The Many -- In General ('''*Unmarked Spoilers*''')]]

Monstrous undead abominations, created by Alan Jonah's experiments on Ghidorah's DNA from the decapitated head while Ghidorah was regenerating.

----

* BloodKnight: Vivienne notes that Ni/Elder Brother always cared more about fighting and killing for the sheer sake of it, compared to how Ichi/Eldest Brother takes glee in tormenting Ghidorah's prey pre-mortem. This particular shed skin is even more AxCrazy about violence than the normal Ni is.

* DaylightHorror: Briefly. He makes his DynamicEntry during the day, and unlike when the Many's Skullcrawler-made {{Mind Hive}}s attacked, there's no prominent storm accompanying him in the sky.

* ExpendableClone: As a shed skin, he's regarded by Ghidorah as nothing more than a fake of the real Elder Brother/Second, [[SmallNameBigEgo despite his denial]].

* FatalFlaw: Over-the-top sadism like Ghidorah, which is coupled with the lack of a RestrainingBolt making [=MaNi=] take this to TooDumbToLive levels. Monster X takes advantage of it to lure [=MaNi=]/Elder Brother to his end.

* HateSink: He's arguably the biggest one in the entire story. He spends the majority of his screentime brutalizing and torturing Monster X with a sadistic grin on his face or otherwise plotting to do so; he even [[spoiler:attempts to kill San in front of Vivienne (and almost succeeds), and gleefully targets the infant Manda solely because of how it'll affect Vivienne]]. Ghidorah, as despicable as it is can at least be vaguely admired for its cunning and for Ichi/Eldest Brother's sophisticated FauxAffablyEvil, but [=MaNi=] doesn't even have either of those things going for him: he's a slobbering-with-bloodlust, rape-y maniac and he takes StupidEvil to TooDumbToLive levels. [[https://hrodvitnon.tumblr.com/post/653738862095532032/ One reader]] gave him the Fan Nickname, Grade A [=GigaBastard=] Supreme.

* PsychoticSmirk: He has one on his face right before he [[spoiler:stabs Monster X]] in Chapter 16.

* SnakesAreSinister: If the fact he's a shed skin of Ghidorah isn't enough, there's also that his body incorporates both a Skullcrawler ''and'' a Warbat into it. Maybe Ghidorah just favors serpentine creatures as worthy pawns because of their resemblance to it?

*** Abaddon and Megiddo are both named after biblical places of destruction, with the latter being believed by scholars to be the site of the FinalBattle between good and evil in Armageddon (fitting the namer, Walter Simmons', [[KnightTemplar delusions that he's the good]] and the implications that he views starting a war against the Titans as Armageddon). The former name also refers to an archangel of the bottomless pit (fitting the Zmeyevich's origin from [[SatanicArchetype Ghidorah]], which rose from a pit in Antarctica to bring apocalyptic destruction).

* HornedHumanoid: He has an overall humanoid/primate build and ram-like horns curling from his head.

* TheNoseKnows: He notes that Vivienne/Monster X has some of the same scent on her that Serizawa did.

* EasilyForgiven: Not directly to his face, but Lauren Griffin in Chapter 14 doesn't seem to hold any grudge for his massacre of the Raptors before he fell under Ghidorah's control during the movie (which to be fair, he was provoked to).

* MixAndMatchCritters: He's a mostly reptilian-looking SeaSerpent who has four limbs for land-crawling, mammalian-looking antlers, catfish-like whiskers, and cerata-like appendages similar to some deep sea invertebrates. According to [[https://hrodvitnon.tumblr.com/post/695791825354620928/ Word of God]], Manda is similar to crocodiles and snakes in that he's born self-sufficient enough to be able to gather and eat food on his own.

* YouGotSpunk: {{Exaggerated}}. He specifically relishes in seeing Vivienne go into a rage state, and he ''especially'' enjoys butchering Vivienne and enraging/maddening her into trying to butcher him.

* SmugSuper: Ichi/Eldest Brother shows the ego part of this trope the most, but all three heads express a high opinion of Ghidorah in the BadassBoast. It's not an understatement, as a ''badly weakened'' Ghidorah was capable of holding its own against '''seven''' Earth Titans [[spoiler:plus Monster X, and the ending heavily implies Ghidorah can still come BackFromTheDead again]].

* BrownNote: The decapitated head's psychic influence seems to cause this, driving to suicide those who don't suffer TheCorruption type SanitySlippage.
* CannotTellALie: It's a case of VillainsNeverLie (see below), but according to [[https://hrodvitnon.tumblr.com/post/648508725162803200/ Word of God]], this trope was also a big influence on Ghidorah [[spoiler:forming a particular part of its EvilPlan for Monster X when it learned of human metaphors]].

* MoralMyopia: It despises [[spoiler:its long-dead alien makers]], yet none of its attached heads seem to quite realize (or just don't care) that they've become exactly the same as them – something which San after his HeelFaceTurn calls his brothers out on. Ichi/Eldest Brother in particular is extremely vindictive when anything besides himself and his brothers reminds him of [[spoiler:the makers]].
* MoreThanMindControl: [[https://hrodvitnon.tumblr.com/post/684182475131551744/ Word of God]] indicates it inflicted this on [[spoiler:Jonah before his SanitySlippage got really bad, giving his thoughts a slight ''nudge'' that ultimately made him obsessively believe he could resurrect a lost loved one]].

* PlanetDestroyer: Slightly downplayed in that from what we know, Ghidorah doesn't (usually) destroy the physical planets themselves but it ''does'' wipe out all dominant life and most to all of the biosphere. It's confirmed that Ghidorah attacked, conquered and ruined numerous alien worlds that had intelligent life on them before its arrival on ancient Earth brought it into conflict with Godzilla, and San's memories further confirm quite-explicitly that Ghidorah covered most of these previous worlds in a global version of [[PerpetualStorm Ghidorah's hurricane]] post-conquest.

* TerribleTicking: A nasty variant. As [[https://hrodvitnon.tumblr.com/post/645147573238333440/ described by the author]], a singular demand known to Ghidorah as "the Old Noise" [[spoiler:was deliberately programmed by Ghidorah's creators into it]] and exists in its three minds: '''Kill Them All'''. It's actually this that drove Ghidorah to repeatedly commit genocide at first. The author thinks it's faded to something like tinnitus after billions of years, but by the time this happened it had [[SlowlySlippingIntoEvil fully taken its toll on Ghidorah's minds]]. The author went into [[https://hrodvitnon.tumblr.com/post/666120662644080640/ further detail]] here.

* BigBrotherBully: Ichi and Ni towards San. They didn't show him a shred of affection nor allow him to indulge in anything that didn't involve eating and killing; roaring in his ears and biting at his horns when they disapproved of his curious tendencies.

* EvilCannotComprehendGood: [[spoiler:{{Subverted}} with San-2/Youngest Brother in [[https://www.fanfiction.net/s/13357907/17/ Chapter 17]]. He at first can't understand why Vivienne won't respond to him or his brothers the way she responds to Mothra and San, but after he has a lengthy psychic talk with Viv and San coupled with seeing Thor's memories of his family, San-Who-Could-Have-Been ends up making a RedemptionEqualsDeath]].

* UsedToBeASweetKid: Apparently, Ichi/Eldest Brother used to be a genuinely nurturing older brother before [[spoiler:the Makers and the Old Noise]] got to him, with [[https://hrodvitnon.tumblr.com/post/680115466430283776/ Word of God]] further indicating he used to be much like [[NiceGirl Vivienne]].

** Part of the reason why Ichi/Eldest Brother hated Vivienne as much as he did was because her building a "cage" around Ghidorah reminded him of creatures from his past that he ''really'' hates: [[spoiler:Ghidorah's Makers]]. [[https://hrodvitnon.tumblr.com/post/677549009646272512/ Word of God]] suggests that Ni/Elder Brother initially has a more adverse hatred of Vivienne than Ichi's obsessive hatred because Vivienne actually reminds Ni of ''Ichi'', [[spoiler:back when the latter [[VirtueIsWeakness still had goodness in him]]]].

* AndYourLittleDogToo: He [[spoiler:rips San's head off of Monster X and attempts to [[SwallowedWhole eat him]] in front of Vivienne]]. And then in Chapter 17, he briefly targets Manda the moment he realizes Monster X cares for the infant.

* EvilCounterpart: He's one to San. Both are formerly Ghidorah's heads which have split off and become "shed skins" and are subsequently no longer considered by Ghidorah's attached heads to be their real brother. But whereas San has Vivienne as his sister, loves her, has made a HeelFaceTurn and has mutually disowned his brothers; [=MaNi=] has no sibling attached to him, he viciously exhibits a perverse narcissistic lust towards Vivienne when tormenting Monster X, he's still devoted to Ghidorah's OmnicidalManiac way, and [[SmallNameBigEgo he still insists he's a part of Ghidorah]].

* HumanoidAbomination: They're {{Monstrous Humanoid}}s resembling a cross between a small monkey and Ghidorah's reptilian characteristics, and it's ambiguous just how much of their three-headed father's EldritchAbomination they've got in them, but it's implied they're Ghidorah's emergency backup way of coming BackFromTheDead.

* BattleCouple: It's ''heavily'' implied that Barnes got it right in ''King of the Monsters'' when he assumed Godzilla and Mothra's symbiotic relationship meant their relationship was also romantic.

* ParentalSubstitute: He seems to be juggling the duty of caring for the newborn Manda with Godzilla and Monster X.

* CatlikeDragons: His physical body language as an infant is a lot like a kitten, which gets briefly {{lampshaded}}.

* AuthorityEqualsAsskicking: It's made clear that if necessary, he will do this to keep the other Titans in line and maintain his global territory's balance.

* ADateWithRosiePalms: When answering a question about Monster X's reproductive cycle, [[https://hrodvitnon.tumblr.com/post/658533139751256064/ the author]] humorously suggested that Ghidorah probably did this once in a while as stress relief inbetween destroying worlds. Being a sociopathic OmnicidalManiac that's out to kill everything it encounters probably limited its fuck-buddy options.

* HostileTerraforming: San's memories indicate Ghidorah has converted the skies of previous alien worlds it conquered into a planet-wide version of [[TheStormbringer the tempest that forms around Ghidorah on Earth]] (which would logically spell certain extinction for any lifeforms on those conquered worlds that were neither highly adaptable nor used to similar environmental conditions); and [[https://hrodvitnon.tumblr.com/post/685085904520527872/ Word of God]] indicates Ghidorah overall makes sure to SaltTheEarth on every planetary conquest before finishing. It's made clear by Ghidorah's [[SpaceNomads Space Nomad]] past and by Monster X's ability to live on Earth just fine that this isn't in any way a necessity to make the environment more suitable for Ghidorah, it's just a way of making its mark on a conquered world and asserting its dominance over all other lifeforms.

* TheNightThatNeverEnds: San's memories indicate that Ghidorah converted the skies of alien worlds it previously attacked into a global version of the alien superstorm which forms around Ghidorah on Earth, which naturally blotted out those worlds' sunlight permanently.

* OmnicidalManiac: It's made clear that from Ghidorah's perspective, everything besides itself is either a toy for extending its destructive rampage, or otherwise consists of food and insects which exist solely to be played with and then killed. As revealed by San's memories and further elaborated on by [[https://hrodvitnon.tumblr.com/post/649738995841024000/ Word o]][[https://hrodvitnon.tumblr.com/post/685085904520527872/ f God]], Ghidorah has devoted its immortal life to traveling from world to world, basically inflicting the same apocalypse we saw it try to inflict in ''King of the Monsters'' on each one, and [[SaltTheEarth salting the leftover rock]] before it moves on. [[Film/IndependenceDay And we're next]]. Not only that, but [[https://hrodvitnon.tumblr.com/post/676003150839398400/ Word of God]] indicates Ghidorah could trigger a ApocalypseHow/ClassX on the ApocalypseHow scale if it succeeds in [[spoiler:its new plan to devour the Earth's [[PlanetaryCoreManipulation Zohar]]]]. This trope is even reflected in the TerribleTicking [[spoiler:which ultimately moulded Ghidorah's personalities into this trope in the first place, simplistically screaming at the backs of Ghidorah's heads, "'''KILL THEM ALL'''"]].

* SaltTheEarth: True to how San's memories reveal Ghidorah converts the atmospheres of the worlds it conquers into a [[PerpetualStorm global version of Ghidorah's hurricane]], [[https://hrodvitnon.tumblr.com/post/685085904520527872/ Word of God]] indicates Ghidorah will make sure to render its planetary conquests unable to grow new life after annihilating the native opposition.

* WoobieDestroyerOfWorlds: Its {{backstory}} before coming to Earth reveals Ghidorah is originally this. [[spoiler:As described in Chapter 10 and [[https://hrodvitnon.tumblr.com/post/645147573238333440/ further elaborated on by the author]]; Ichi, Ni and San were originally just three critters in an alien ecosystem fighting together to survive, before they were captured, forcibly transformed into Ghidorah and [[BeingTorturedMakesYouEvil methodically tortured]]. Ghidorah exterminated its tormentors in a combination of revenge and desperation to satiate the TerribleTicking they'd programmed into the three heads, but this failed to bring Ghidorah any peace or satisfaction. Ghidorah inflicted mass destruction again and again trying to make the Ticking stop, and SlowlySlippingIntoEvil gradually destroyed what goodness Ichi/Eldest Brother and Ni/Elder Brother still had in them until they became the monstrously cruel OmnicidalManiac we all know Ghidorah as]].

* BaddieFlattery: San-Who-Could-Have-Been/Youngest Brother and [[spoiler:Ichi/Eldest Brother]] both compliment Monster X (specifically Vivienne) a couple times on how strong and ferocious a creature she's grown into, and on her performance against [[spoiler:Ghidorah]].

* ZombieInfectee: [[spoiler:PlayedWith. In Chapter 17, he gets infected by the Many, but he genuinely doesn't know it and is unconvinced when Scylla tells him so, until Mothra makes him aware. Mothra trusts Thor to continue fighting with her until his HeroicSacrifice]].

* PlanetDestroyer: Slightly downplayed in that from what we know, Ghidorah doesn't (usually) destroy the physical planets themselves but it ''does'' wipe out all dominant life and most to all of the biosphere. It's confirmed that Ghidorah attacked, conquered and ruined numerous alien worlds that had intelligent life on them, before its arrival on ancient Earth and conflict with Godzilla, and San's memories furthermore quite-explicitly confirm that Ghidorah covered most of these worlds in a global version of [[PerpetualStorm Ghidorah's hurricane]] post-conquest.

* ThereIsNoKillLikeOverkill: The Titans often have to {{invoke}} this to try and fully incapacitate the Many's Mind Hives, destroying as many leftover pieces as possible.

* AxCrazy: [=MaNi=] is "batshit crazy", as the ''King of the Monsters'' director once said when referring to the movie portrayal of Ni. He has a hard-on for the idea of driving Vivienne to commit mindless violence, described by [[https://hrodvitnon.tumblr.com/post/648508725162803200/ the author]] as a "murder boner", combined with Ghidorah's usual penchant for violence and cruelty.

* UniformityException: Methuselah reveals that his species' coats are usually gray, instead of red like his is.

* MakeSureHesDead: The Earthborn Titans are intelligent enough to realize that they need to kill ''every last piece'' of the Many's {{Mind Hive}}s, so Rodan and Scylla both take extra precautions to make sure the Many and their pieces are 100% dead.

* ThereIsNoCure: Monster X at one point begs San-Who-Could-Have-Been/Youngest Brother to purge a Many-infected living Titan of the Many's cells, but San-Who-Could-Have-Been's thoughts reveal he and his brothers can't remove the infection even if they wanted to.

* UniformityException: Methuselah reveals that his species' coats are usually gray, instead of red like his.

* CowardiceCallout: He directly calls Thor a coward almost as soon as they see each-other for the first time since the Mass Awakening, referring to how Thor preserved his own life in hiding whilst the rest of his kind died fighting Ghidorah, which enrages Thor.

* DragonsAreDivine: He's a friendly, marine Protector Titan who closely resembles the traditional depiction of eastern dragons as short-legged, snake-bodied creatures, he's born in and sets up his territory in the Pacific/East China Sea, and he overall seems set to follow in his forebears' footsteps whilst doing all of the above.

* EnemyToAllLivingThings: It threatens pretty much all life, it's confirmed here to be a serial PlanetDestroyer, and it's despised by Earth's native Titans (forces of nature embodied) as "the Enemy".

* PlanetDestroyer: Slightly downplayed in that from what we know, Ghidorah doesn't (usually) destroy the physical planets themselves but it ''does'' wipe out all dominant life and likely the majority/entirety of the native biosphere. It's confirmed that Ghidorah attacked, conquered and ruined numerous alien worlds that had intelligent life before its arrival on ancient Earth and conflict with Godzilla, and San's memories furthermore quite-explicitly confirm that Ghidorah covered most of these worlds in a global version of [[PerpetualStorm Ghidorah's hurricane]] post-conquest.

* TheDarknessGazesBack: They pull this off with their GlowingEyesOfDoom in darkness.

* AxCrazy: He's "batshit crazy" as the ''King of the Monsters'' director once said when referring to the movie portrayal. He has a hard-on for the idea of driving Vivienne to commit mindless violence, described by [[https://hrodvitnon.tumblr.com/post/648508725162803200/ the author]] as a "murder boner", combined with Ghidorah's usual penchant for violence and cruelty.

* ColorCodedCharacters: Methuselah reveals he's an InUniverse case, as his species' coats are usually gray instead of red.

** He can also be seen as one to Mark Russell when they briefly interact. Mark held MisplacedRetribution towards Godzilla for years after the latter unintentional caused his son's death; whereas Thor[[spoiler:'s son was intentionally and viciously killed by Ghidorah, but Thor found it in himself to take a SparedButNotForgiven attitude towards San]].

* BigScrewedUpFamily: Its EvilPlan [[spoiler:after regenerating]] involved forming an UpToEleven case of this – [[spoiler:inflicting BeingTorturedMakesYouEvil on their "[[AntiAntichrist sister-daughter]]" Vivienne to make her like them, with the Many as Ghidorah's thralls]], and both San-2/Youngest Brother and the Many outright call it a family.

* BigScrewedUpFamily: Taken UpToEleven. Like their master, they have a twisted idea of their HiveMind, the slowly-regenerating Ghidorah, and Ghidorah's "[[VillainousIncest sister-daughter]]" as a growing family.
* BodyHorror: The Many are particularly gruesome; the author having looked at bone cancer among her inspirations for their appearance. Taken UpToEleven when they perform FusionDance.

* {{Dehumanization}}: A variation. [[spoiler:It considers any of its heads that have detached from Ghidorah's main body and become autonomous creatures to be nothing more than "shed skins" or "shadows" which are inferior to Ghidorah, despite said shed skins retaining their personalities]]. [[https://hrodvitnon.tumblr.com/post/690309147799011328/ Word ofGod]] has talked more about how and when Ghidorah developed this attitude in its backstory.

* MotiveDecay: Ghidorah is revealed via its backstory to be an InUniverse case. [[spoiler:It began killing beyond its TurnedAgainstTheirMasters because it was at first just trying to make "[[TerribleTicking the Old Noise]]" stop, and it aimed to kill {{Asshole Victim}}s; with [[https://hrodvitnon.tumblr.com/post/690309147799011328/ Word of God]] even suggesting that at least ''some'' of these early victims Ghidorah targeted were [[ButWhatAboutTheAstronauts extraplanetary survivors]] of [[AbusivePrecursors the Makers]]' species]]. As time passed however, Ghidrah wholly devolved into an OmnicidalManiac, concerned only with hatred of all life that even vaguely resembles [[spoiler:the Makers]] and satisfying its endless bloodlust.

* OmnicidalManiac: It's made clear that from Ghidorah's perspective that everything besides itself is either a toy for extending its destructive rampage, or otherwise consists of food and insects which exist solely to be played with and then killed. As revealed by San's memories and further elaborated on by [[https://hrodvitnon.tumblr.com/post/649738995841024000/ Word o]][[https://hrodvitnon.tumblr.com/post/685085904520527872/ f God]], Ghidorah has devoted its immortal life to traveling from world to world, basically inflicting the same apocalypse we saw it try to inflict in ''King of the Monsters'' on each one and [[SaltTheEarth salting the leftover rock]] before it moves on. [[Film/IndependenceDay And we're next]]. Not only that, but [[ Word of God]] indicates Ghidorah could trigger a ApocalypseHow/ClassX on the ApocalypseHow scale if it succeeds in [[spoiler:its plan to devour the Earth's [[PlanetaryCoreManipulation Zohar]]]]. This trope is even reflected in the TerribleTicking [[spoiler:which ultimately moulded Ghidorah's personalities into this trope in the first place, simplistically screaming at the backs of Ghidorah's heads, "'''KILL THEM ALL'''"]].

* PlanetDestroyer: Slightly downplayed in that from what we know, Ghidorah doesn't (usually) destroy the physical planets themselves but it ''does'' wipe out all dominant life and likely the majority/entirety of the native biosphere. It's confirmed that Ghidorah attacked, conquered and ruined numerous alien worlds that had intelligent life before its arrival on ancient Earth and conflict with Godzilla, and San's memories furthermore reveal that Ghidorah covered most of these worlds in a global version of [[PerpetualStorm Ghidorah's hurricane]] post-conquest.

* UncertainDoom: {{Inverted}}. The last that's seen of him is what's left of his severed head becoming inanimate due to overusing its LifeEnergy reserve, and his body getting completely sucked dry of its own energy. However, we never see whether or not his remains were subsequently incinerated to render him mostly dead, and [[https://hrodvitnon.tumblr.com/post/690163715553820672/ Word of God]] has hinted that if his remains remained un-incinerated, then he remains OnlyMostlyDead and could come back.

* {{Dehumanization}}: A variation. [[spoiler:It considers any of its heads that have detached from Ghidorah's main body and become autonomous creatures to be nothing more than "shed skins" or "shadows" which are inferior to Ghidorah, despite said shed skins retaining their personalities]].

* MotiveDecay: Ghidorah is revealed via its backstory to be an InUniverse case. [[spoiler:It began killing beyond its TurnedAgainstTheirMasters because it was at first just trying to make "[[TerribleTicking the Old Noise]]" stop, and it aimed to kill {{Asshole Victim}}s, but it (particularly Ichi and Ni) eventually completed the SlowlySlippingIntoEvil]].

* OmnicidalManiac: It's made clear that Ghidorah sees everything that isn't itself or a Ghidorah-derived lifeform as food or toys to be played with and killed. As revealed by San's memories and further elaborated on by [[https://hrodvitnon.tumblr.com/post/649738995841024000/ Word o]][[https://hrodvitnon.tumblr.com/post/685085904520527872/ f God]], Ghidorah has devoted its immortal life to traveling from world to world, basically inflicting the apocalypse we saw it try to inflict in ''King of the Monsters'' on each one and [[SaltTheEarth salting the leftover wasteland]] before it moves on. [[Film/IndependenceDay And we're next]]. This trope is even reflected in the TerribleTicking [[spoiler:which ultimately moulded Ghidorah's personalities into this trope in the first place, simplistically screaming at the backs of Ghidorah's heads, "'''KILL THEM ALL'''"]].

* PlanetDestroyer: A somewhat mild case. Ghidorah has conquered and subsequently ruined numerous alien worlds before its arrival on ancient Earth and conflict with Godzilla. San's memories reveal that Ghidorah tends to blanket the worlds it conquers in a global version of [[PerpetualStorm Ghidorah's hurricane]], and [[https://hrodvitnon.tumblr.com/post/649738995841024000/ Word of God]] elaborates further on how Ghidorah conquers and wrecks each of these worlds.

* UncertainDoom: {{Downplayed}}. [[https://hrodvitnon.tumblr.com/post/689311522082668544/ Word of God]] indicates that Monster X's VampiricDraining and the expiration of his severed upper-head's LifeEnergy in themselves might have merely rendered him OnlyMostlyDead, and we don't see whether or not Monster X disposes of [=MaNi's=] remains in a way that renders them permanently dead and unable to recharge afterwards.

* HostileTerraforming: San's memories indicate Ghidorah has converted the skies of previous alien worlds it conquered into a planet-wide version of [[TheStormbringer the tempest that forms around Ghidorah on Earth]] (which would logically spell certain extinction for any lifeforms on those conquered worlds that were neither highly adaptable nor used to similar environmental conditions); and [[https://hrodvitnon.tumblr.com/post/685085904520527872/ Word of God]] indicates Ghidorah overall makes sure to SaltTheEarth on every planetary conquest before finishing. It's made clear by Ghidorah's [[SpaceNomads Space Nomad]] past and by Monster X's ability to live on Earth just fine that this isn't in any way a necessity to make the environment more suitable for Ghidorah, it's just a way of making its mark on a conquered world and assert its dominance over all other lifeforms.

* AdaptationalBadass: Besides [[Characters/MonsterVerseKingGhidorah the points racked up by]] [[Characters/MonsterVerseKingGhidorah MonsterVerse canon Ghidorah]] relative to earlier licensed continuities' portrayals, there's also the fact that this story's version of Ghidorah [[spoiler:was able to break free of its alien former-masters' control without any assistance, if they even had any real control over it to begin with (but from [[https://hrodvitnon.tumblr.com/post/645147573238333440/ what the author has said]], it's possible that those aliens probably just didn't value their lives enough to try placing restraints on their own creation)]]. Furthermore; Ghidorah's PsychicPowers even when it's reduced to a single head are demonstrably more intense here than in [=MonsterVerse=] canon, and Ghidorah in this story is able to regenerate fully FromASingleCell with all three minds intact (whereas [=MonsterVerse=] Ghidorah's remains were an UndeadAbomination that only demonstrably retained Ghidorah's SoulFragment).

* EnemyToAllLivingThings: It's confirmed as being a PlanetDestroyer, and is despised by Earth's native Titans as "the Enemy".

* KnightOfCerebus: {{Downplayed}} in that the work is already dark and edgy even without Ghidorah's direct presence. But once [[spoiler:Keizer Ghidorah returns to center stage, things turn even more serious: it torments Monster X underground, and absorbs an entire city's population in advance of the MonsterDelay's end]]. It helps that whereas Alan Jonah is a SmugSnake and [=MaNi=]/Elder Brother is StupidEvil, Ghidorah is more of a SmugSuper.

* PragmaticVillainy: If you've read what it plans to do to Vivienne, then you'll know that it [[spoiler:saving Monster X]] is ''not'' gonna be a good thing if Ghidorah gets its way with them immediately afterwards. There's also San-2/Youngest Brother [[spoiler:protesting to his brothers causing too much physical damage to Monster X more because he's concerned it'll irreparably break what San-2 sees as a beloved toy than out of humaneness]].

* RealAfterAll: [[spoiler:It's eventually revealed in Chapter 9 that Ni and Ichi's voices breaking San down when he was viewing Vivienne's memories really were them, and weren't just San's guilt]].

* SatanicArchetype: Like in the movie. Vivienne always called it the Devil or the Dragon in her notes, it's often compared by human characters' narration to a devil, and [[spoiler:it serves as the [[WesternAnimation/TeenTitans2003 Trigon to Monster X's Raven]]]]. Like Satan, Ghidorah[[spoiler:'s descent into darkness began with it turning against its creators (similar to Satan's rebellion against God)]], and the EvilMakesYouUgly (see above) brings to mind Satan's tansformation from a beautiful angel into a devil as a consequence of his crimes. The fates of humans who fall victim to Ghidorah's use of the Many, and [[spoiler:Ghidorah primarily residing in subterranean tunnels where its psychic influence is strong and it rules over the Many]], both bring to mind the idea of {{Hell}} with Satan ruling over its denizens and damned humans, while [[spoiler:Keizer Ghidorah assimilating the Many]] brings to mind a devil taking souls inside itself for power. Ghidorah's heads also [[spoiler:[[AsTheGoodBookSays quote the Serpent in the Book of Genesis]], specifically when the Serpent is tempting Eve]], and Ghidorah shows an aptly Satan-like level of hubris in how [[spoiler:the heads misinterpret or deliberately pervert the verse's meaning[[note]]Genesis 3:5 refers to how humans ''can't'' be like God, but Ghidorah uses the verse in reference to its plan to turn Vivienne into what Ghidorah views as a ''true'' god as well as in reference to her and the Many becoming enslaved to the Devil's (Ghidorah's) corruptive influence[[/note]]]]. It's hinted in Chapter 13 that [[{{Satan}} the Devil]] might literally be humanity's mythical memory of Ghidorah.

* StrawNihilist: It has shades of this, viewing all other life as temporary and worthless. According to [[https://hrodvitnon.tumblr.com/post/645147573238333440/ the author]], it's rooted in Ghidorah's own realization during its SlowlySlippingIntoEvil that asking why [[spoiler:it was the victim of such tragedy and what the point of its ReluctantPsycho programming was]] were pointless because there ''was'' no higher reason for it.

* SuperEmpowering: There's what San did to Vivienne when he transformed her body into an ArtificialHybrid by feeding his Ghidorah biology's enzymes into her inside his neck's "womb". Plus [[spoiler:[[TranshumanAbomination the Many]] are a lot more durable and deadly than when they were autonomous living creatures]].

* BeingEvilSucks: San-2/Youngest Brother suffers this exactly like San did; getting no love and only the scarcest respect from his abusive brothers, and being more interested in having a new sister than [[OmnicidalManiac Omnicidal Mania]].
* BerserkButton: Ichi/Eldest Brother specifically was ticked off by humans (namely Vivienne) building a "cage" around Ghidorah while it was frozen. It's also revealed that Ghidorah has such an extreme reaction to hearing an ORCA signal because it [[spoiler:brings back bad memories from Ghidorah's {{Backstory}} as a TorturedMonster]]. It's heavily implied in the story, and confirmed by [[https://hrodvitnon.tumblr.com/post/677549009646272512/ Word of God]], that Ghidorah goes into KillAllHumans mode when it encounters humans and has actively wiped out civilizations on other worlds purely because Ichi and Ni (Ichi especially) despise any reminder of [[spoiler:the human-like AbusivePrecursors who tortured them]].

* DoppelgangerGetsSameSentiment: {{Averted}} hard by Vivienne in regards to San-2/Youngest Brother, as she has no interest in fulfilling this trope nor the implications of doing so. [[spoiler:However, during the FinalBattle, Monster X recognizes San-2 as indeed being "San-Who-Could-Have-Been" and mourns his RedemptionEqualsDeath HeroicSacrifice]].

* InLoveWithYourCarnage: [[spoiler:Both Ichi/Eldest Brother and Ni/Elder Brother react this way towards Vivienne after witnessing Monster X's capacity for savagery. They subsequently wants to mentally destroy Vivienne until this violent streak becomes the entire definition of her personality, with [[https://hrodvitnon.tumblr.com/post/677549009646272512 Word of God]] noting Ni in particular is interested in the [[RapeIsASpecialKindOfEvil raping]] part]].
* InSeriesNickname: In {{canon}}, Ghidorah's heads were only named Ichi, Ni and San as a ProductionNickname and were never called this InUniverse. In this fic, it's revealed in [[https://www.fanfiction.net/s/13357907/2 Chapter 2]] that Vivienne gave the heads their names while she was monitoring Outpost 32. Ichi and Ni seemingly don't answer to these names, and are referred to by San as Eldest Brother and Elder Brother respectively. San-2/Youngest Brother eventually earns the name San-Who-Could-Have-Been from Monster X.

* YouAreACreditToYourRace: {{Inverted}} by Ichi/Eldest Brother and Ni/Elder Brother; they described Thor to the latter's face as being even more lowly than the rest of his "misbegotten kind" (Ni's words) for fleeing Ghidorah's genocide instead of fighting back.

* AssimilationPlot: This is the Many's general attitude towards anything that isn't them or their three-headed originator, if it's worthy of anything other than dying.

* BodyHorror: The Many are particularly gruesome, the author having looked at bone cancer among her inspirations for their appearance. Taken UpToEleven when they perform FusionDance.

* EldritchTransformation: The Many gradually transform bodies into a monstrous, pulsating MindHive of BodyHorror, whilst assimilating whatever remains of the victimns' consciousnesses into the UndeadAbomination[='s=] HiveMind.

* HybridsAreACrapshoot: Weld unrefined Ghidorah DNA onto human bodies, and you get an undead, part-Ghidorah expy of Film/TheThing.

* TheMorlocks: Their initial humanoid forms, though technically TheVirus, have definite shades of this. They lurk in dark underground spaces, they have very Morlock-like eyeshine, these forms are even created from the {{Disposable Vagrant}}s whom were being used as labor.

* ThereIsNoKillLikeOverkill: The Titans often have to use this to try and fully incapacitate the Many's Mind Hives, and attempt to destroy as many leftover pieces as possible to be sure.

* HotBlooded: He's a vicious, extra-sadistic loonie who's about as calm-headed as a desert is cold; literally salivating at the prospect of getting violent with Monster X, and throwing tantrums when his patience wears thin.

* InLoveWithYourCarnage: Calling it "love" would be a gross misuse of the word, but otherwise this trope is PlayedStraight by him in regards to Vivienne's capacity for Ghidorah-like extreme violence. The author comments he has a "murder boner", [[https://hrodvitnon.tumblr.com/post/677549009646272512 and that]] he wants the copulating part even more than Ichi/Eldest Brother.

* MonstrousCannibalism: Sort-of. Highlighting how monstrous he is, [=MaNi=]/Elder Brother has no compunctions whatsoever against eating certain pieces of Monster X (a half-Ghidorah, half-something else fusion like [=MaNi=]) just to torment them. Ultimately ZigZagged, since the heroic Monster X is just fine with repaying him in kind.

* OurDragonsAreDifferent: After gaining a single-headed, one-tailed body via the Many, he now possesses four crawling limbs, and also two wings apparently assimilated from a [[Film/GodzillaVsKong Warbat]]. He's even more blatantly vicious than Ni/Elder Brother usually is, and covets Vivienne so he can torment her and revel in her violence.

* HumanoidAbomination: They're {{Monstrous Humanoid}}s resembling a cross between a small monkey and Ghidorah's reptilian characteristics, and it's ambiguous just how much of their three-headed father's EldritchAbomination they've got in them but it's implied they're Ghidorah's emergency backup way of coming BackFromTheDead.
* HybridsAreACrapshoot: Downplayed. They're fully functional creatures from what we see and they lack the Many's BodyHorror or Monster X's first form's crippling defects, but they certainly didn't inherit [[BeautyIsBad Ghidorah's good looks]].

*** Abaddon and Megiddo are both named after biblical places of destruction, with the latter being believed by scholars to be the site of the FinalBattle between good and evil in Armageddon (fitting the namer, Walter Simmons', [[KnightTemplar delusions that he's the good]] and the implications that he views starting a war against the Titans as Armageddon). The former name also refers to an archangel of the bottomless pit (fitting the Zmeyevich's origin from [[SatanicArchetype Ghidorah]], which rose from a pit in Antarctica to bring apocayptic destruction).

* DugTooDeep: {{Averted}} according to [[https://hrodvitnon.tumblr.com/post/662352391279149056/ Word of God]], when a construction operation first discovered him in the past but didn't disturb his slumber in the process.

* SuspiciouslySimilarSubstitute: A Titan resembling a giant ape who's fierce yet seems to have a stronger emotional connection to humans because they're primates, is protective of the female protagonist in an almost paternal manner, personally hates a reptilian BigBad (due to [[spoiler:them killing his family in the past no less]]), and was able to stubbornly reject Ghidorah's alpha call during the Mass Awakening. Sound like anyone? The [=AbraxasVerse=] Timeline and further [[https://hrodvitnon.tumblr.com/post/656635359659180032 Word of God]] even suggest that the two characters' species share a history.

* {{Mangst}}: He's lamentful when mentioning his late friend the Lord of Dragons in Chapter 13.
* MirrorCharacter: To Monster X as more details of his personality and past come to light. Being tired and world-weary from having lived so long, fought so many foes and having outlived ''all'' his kin and many of his old friends; Godzilla is arguably a reflection of what [[LongLived Monster X]] will liably be like after thousands or millions of years.

* RunningOnAllFours: [[spoiler:He at one point charges into the fray this way in Chapter 17]].

* UnderestimatingBadassery: He's confident he can match Monster X in a fight when he first encounters them, but is later disturbed and impressed by San and Vivienne's ferocity when they're truly pissed off.

* {{Foil}}: To Monster X. Monster X is an ArtificialHybrid created by [[SatanicArchetype Ghidorah]] (and half of them is a BackFromTheDead former-human with their memories intact) with a lot of trauma, whereas Manda is a possible {{Reincarnation}} of a former-human as a divine reward and is innocent.

A bat-like Destroyer Titan which attacked San Diego during the Mass Awakening, and is transcribed in ancient hieroglyphs on Skull Island.

* OnlyMostlyDead: [[https://hrodvitnon.tumblr.com/post/690163715553820672/ Word of God]] indicates he might actually be in this state rather than permanent death after his head's remains expended its backup LifeEnergy and after his body was sucked dry of its energy, and that the Many might be able to revive him.

* UncertainDoom: {{Downplayed}}. [[https://hrodvitnon.tumblr.com/post/689311522082668544/ Word of God]] indicates that his body might not have been permanently killed but merely rendered inert, and it's unknown if his head's severed remains can come back to life if its drained LifeEnergy is renewed, plus we don't see whether or not Monster X disposes of [=MaNi's=] remains in a more surefire way after he becomes "inactive".

* WeCanRebuildHim: [[https://hrodvitnon.tumblr.com/post/690163715553820672/ Word of God]] suggests he might be on the receiving end of a variation: surviving pieces of [[TheAssimilator the Many]] might have taken his remains away looking to resurrect him in some form

* ItsPersonal: He's eager to get another shot at kicking Ghidorah's ass in some form or another after it bested him and enslaved him during ''King of the Monsters''.

* VitriolicBestBuds: [[https://hrodvitnon.tumblr.com/post/688251237000462336/ The author]] says she likes to think that Rodan has this kind of relationship with his Titan allies generally: they don't exactly act friendly towards him nor he to them, but said Titans ''will'' watch his back.

* AdaptationalBadass: Besides [[Characters/MonsterVerseKingGhidorah the points racked up by]] ''[[Characters/MonsterVerseKingGhidorah MonsterVerse canon Ghidorah]] relative to earlier licensed continuities' portrayals, there's also the fact that this story's version of Ghidorah [[spoiler:was able to break free of its alien former-masters' control without any assistance, if they even had any real control over it to begin with (but from [[https://hrodvitnon.tumblr.com/post/645147573238333440/ what the author has said]], it's possible that those aliens probably just didn't value their lives enough to try placing restraints on their own creation)]]. Furthermore; Ghidorah's PsychicPowers even when it's reduced to a single head are demonstrably more intense here than in [=MonsterVerse=] canon, and Ghidorah in this story is able to regenerate fully FromASingleCell with all three minds intact (whereas [=MonsterVerse=] Ghidorah's remains were an UndeadAbomination that only demonstrably retained Ghidorah's SoulFragment).

* {{Determinator}}: {{Implied}}. Compared to the old Toho incarnations who would flee back into space when defeated, in this story, it seems Ghidorah truly will not stop until it's successfully conquered and destroyed the Earth before it can move on to doing the same to another world. Bear in mind, it's explicitly confirmed in this story that Ghidorah is capable of interstellar travel (whereas ''King of the Monsters'' kept Ghidorah's history before falling to Earth [[MysteriousPast shrouded in mystery]]), yet it tries to kill Godzilla and destroy his world every time it comes back from death.

* HostileTerraforming: San's memories indicate Ghidorah has converted the skies of previous alien worlds it conquered into a planet-wide version of [[TheStormbringer the tempest that forms around Ghidorah on Earth]] (which would logically spell certain extinction for any lifeforms on those conquered worlds that were neither highly adaptable nor used to similar environmental conditions); and [[https://hrodvitnon.tumblr.com/post/685085904520527872/ Word of God]] indicates Ghidorah overall makes sure to SaltTheEarth on every planetary conquest before finishing. It's also made clear by Ghidorah's [[SpaceNomads Space Nomad]] past and by Monster X's ability to live on Earth just fine that this isn't in any way a necessity to make the environment more suitable for Ghidorah, it's just a way of making its mark on a conquered world and asserting its dominance over all other lifeforms.

* TheNightThatNeverEnds: From what San's memories describe, it sounds like Ghidorah converted the skies of alien worlds it previously attacked into a global version of the sun-blotting alien superstorm which forms around Ghidorah on Earth.

* OmnicidalManiac: The story expands on this. Ghidorah is a PlanetDestroyer that actively pounds civilizations into dust, actively devours or exterminates any species that stand up to it or just for the fun of it, and leaves every world it conquers [[TheNightThatNeverEnds completely covered by]] {{Perpetual Storm}}s before it moves on. It devotes its immortal life to wreaking nothing but carnage and destruction, viewing any lifeforms it doesn't repurpose into subservient fellow bringers of destruction as nothing more than food and insects for Ghidorah to play with and then kill..

* PlanetDestroyer: A somewhat mild case. Ghidorah has conquered and subsequently ruined numerous alien worlds before its arrival on ancient Earth and conflict with Godzilla, with [[https://hrodvitnon.tumblr.com/post/649738995841024000/ Word of God]] elaborating on how Ghidorah wrecks each of these worlds before leaving them cinders and moving on.

* SaltTheEarth: True to the implications of San's memories (in which Ghidorah apparently converts the atmospheres of the worlds it attacks into a [[PerpetualStorm global version of Ghidorah's hurricane]]), [[https://hrodvitnon.tumblr.com/post/685085904520527872/ Word of God]] indicates Ghidorah will make sure to render its planetary conquests unable to grow new life after annihilating the native opposition, before Ghidorah sooner or later moves on to its next target.

* LosingYourHead: [[spoiler:Ichi/Eldest Brother's head gets ripped off, and he remains conscious and animate until he's executed]], in Chapter 17. {{Justified}}, as [[https://hrodvitnon.tumblr.com/post/689311522082668544/ Word o]][[https://hrodvitnon.tumblr.com/post/689317106053955584/ f God]] reveals Ghidorah's heads rely on inernal power reserves to remain animate after being decapitated.

* OhCrap: Being confronted with the idea that Ghidorah's enemies might actually be able to hunt down all the pieces of it and thereby make his impending death become permanent was enough to make Ichi/Eldest Brother's eyes fractionally widen despite his efforts to save face [[spoiler:in Chapter 17]].

* EldritchTransformation: The Many gradually transform bodies into a monstrous, pulsating MindHive of BodyHorror, whilst assimilating whatever remains of the humans' consciousnesses into the UndeadAbomination[='s=] HiveMind.
* {{EMP}}: It's theorized by a Monarch operative in Chapter 15 that they used this to knock out Castle Bravo's power.

* AssimilationBackfire: [[https://hrodvitnon.tumblr.com/post/656909793179631616/ Word of God]] reveals part of the reason he's so much more AxCrazy than the regular Ni is due to merging himself with a Skullcrawler and absorbing some of its cognitive impulses. This makes [=MaNi=] TooDumbToLive, but it unfortunately also makes him severely devoid of self-restraint when he gets violent with you. [[https://hrodvitnon.tumblr.com/post/689317106053955584/ Another comment by the author]] reveals that [=MaNi's=] head in his new form can't store as much of his LifeEnergy in it as a pure Ghidorah head can to keep the head alive in case it's severed.

* RasputinianDeath: He gets [[ImpaledWithExtremePrejudice impaled]], paralyzed by a severed spinal chord, his tail is ripped off and [[StopHittingYourself used to beat his skull into pulp]], and ''then'' what's left of his head gets ripped off, and Monster X slowly [[VampiricDraining sucks his headless body dry of energy]] while his head's remains ''finally'' become inanimate due to expending its emergency LifeEnergy. [[https://hrodvitnon.tumblr.com/post/690163715553820672/ Word of God]] indicates this [[UncertainDoom might be]] a [[SubvertedTrope subversion]] of the trope.

* HateSink: He's arguably the biggest one in the entire story. He spends the majority of his screentime before his death brutalizing and torturing Monster X with a sadistic grin on his face or otherwise plotting to do so; he even [[spoiler:attempts to kill San in front of Vivienne (and almost succeeds), and gleefully targets the infant Manda solely because of how it'll affect Vivienne]]. Ghidorah, as despicable as it is can at least be vaguely admired for its cunning and for Ichi/Eldest Brother's sophisticated FauxAffablyEvil, but [=MaNi=] doesn't even have either of those things going for him: he's a slobbering-with-bloodlust, rape-y maniac and he takes StupidEvil to TooDumbToLive levels. [[https://hrodvitnon.tumblr.com/post/653738862095532032/ One reader]] gave him the Fan Nickname, Grade A [=GigaBastard=] Supreme.

* ImpaledWithExtremePrejudice: Getting impaled with a church steeple is just the ''start'' of his KarmicDeath.

* JustDesserts: {{Downplayed}} and {{lampshaded}}. Monster X finishes his RasputinianDeath by VampiricDraining him, turning him into nothing more than food.
* KarmicDeath: He practically gets a RasputinianDeath at the hands of the very same Titan that he viciously tortured and hurt in a rape-like manner and whom he pulled AndYourLittleDogToo on. But more than that, Monster X finishes him off by essentially turning his body into food (exactly what he tried to do to San) while his severed head is helpless to watch (just as Vivienne was almost ForcedToWatch), and his head being ignored before it runs out of power whilst his body's destruction is assured psychologically breaks [=MaNi=] (fitting how he psychologically tortured Vivienne).

* RasputinianDeath: He gets [[ImpaledWithExtremePrejudice impaled]], paralyzed by a severed spinal chord, his tail is ripped off and [[StopHittingYourself used to beat his skull into pulp]], and ''then'' what's left of his head gets ripped off, and Monster X slowly [[VampiricDraining sucks his headless body dry of energy]] while his head's remains ''finally'' become inanimate due to expending its emergency LifeEnergy. Somewhat PlayedWith, as [[https://hrodvitnon.tumblr.com/post/689311522082668544/ Word of God]] says Monster X's VampiricDraining might have merely starved [=MaNi's=] body's cells into stasis rather than death, and it's likewise ambiguous if [=MaNi=]/Elder Brother's head running out of LifeEnergy equates to ''permanent'' death.

* UndignifiedDeath: The final phase of his defeat by Monster X (although it's ambiguous if he was really killed or merely rendered dormant) is an InUniverse case from his perspective, partly because he's being deprived the over-the-top CombatSadomasochist violence he craved.

* AdaptationalBadass: Besides [[Characters/MonsterVerseKingGhidorah the points racked up by]] ''[[Characters/MonsterVerseKingGhidorah MonsterVerse canon Ghidorah]] relative to earlier licensed continuities' portrayals, there's also the fact that this story's version of Ghidorah [[spoiler:was able to break free of its alien former-masters' control without any assistance, if they even had any real control over it to begin with (but from [[https://hrodvitnon.tumblr.com/post/645147573238333440/ what the author has said]], it's possible that those aliens probably just didn't value their lives enough to try placing restraints on their own creation)]]. Furthermore; Ghidorah's PsychicPowers even when it's reduced to a single head are demonstrably more intense here than in [=MonsterVerse=] canon, and Ghidorah in this story is able to regenerate fully FromASingleCell with all three minds intact (whereas [=MonsterVerse=] Ghidorah's remains were an UndeadAbomination that only demonstrably retained Ghidorah's SoulFragment.

* TheAdjectiveOne: The Many call it "the Great One".

* RedBaron: Its titles mentioned during the story include the Devil, the Enemy, the Dragon, the Destroyer of Worlds, the One Who Is Many, That Which Came From The Stars, the Golden Demise, the Snake Father, the World Eater, the Song of Entropy, the Death Knell of Three Storms and [[TheAdjectiveOne the Great One]].

* TokenGoodTeammate: Like San before he fused with Vivienne, San-2 Youngest Brother is the least vicious of the three heads but still not devoid of sadism, and he hates it when his brothers [[spoiler:damage their "toy" too much]].

* SeeTheInvisible: She can see "Life-Strands" of the world, described in Chapter 17.

* CloseRangeCombatant: He seemingly doesn't have much if anything in the way of long-range attacks but can fight ferociously when up-close.

* GlowingEyesOfDoom: Their initial humanoid forms have eyeshine in the dark.

* AssimilationBackfire: [[https://hrodvitnon.tumblr.com/post/656909793179631616/ Word of God]] reveals part of the reason he's so much more AxCrazy than the regular Ni is due to merging himself with a Skullcrawler and absorbing some of its cognitive impulses. This makes [=MaNi=] TooDumbToLive, but it unfortunately also makes him severely devoid of self-restraint when he gets violent with you.

* AxCrazy: He's batshit crazy, with a hard-on for the idea of driving Vivienne to commit mindless violence, and [[https://hrodvitnon.tumblr.com/post/648508725162803200/ the author]] comments he has a "murder boner".

* GoingToGiveItMoreEnergy: {{Inverted}}. [=MaNi=]/Elder Brother is genuinely surprised when he realizes Monster X is VampiricDraining not just a chunk of his energy which he can still survive without, but literally all of it.

* KarmicDeath: He gets a RasputinianDeath at the hands of the very same Titan that he viciously tortured and hurt in a rape-like manner and whom he pulled AndYourLittleDogToo on. But more than that, Monster X finishes him off by essentially turning him into food while his severed head watches, ''just like'' what he tried to do to San when Vivienne was helpless; and going out in such an anticlimactic way as VampiricDraining psychologically breaks [=MaNi=] as he dies, fitting how he psychologically tortured Vivienne.

* LosingYourHead: Monster X rips his upper-skull off his body and makes it helplessly watch what they do to him next.

* RasputinianDeath: He gets [[ImpaledWithExtremePrejudice impaled]], paralyzed by a severed spinal chord, his tail is ripped off and [[StopHittingYourself used to beat his skull into pulp]], and ''then'' what's left of his head gets ripped off, and Monster X slowly finishes him off by VampiricDraining him into oblivion.

* TooDumbToLive: In Chapter 17, he's well aware Monster X is luring him into an ambush and pursues it anyway, despite having no knowledge of what Monster X in its new form is capable of.

* UndignifiedDeath: The final phase of his death is an InUniverse case from his perspective, partly because he's being deprived the over-the-top CombatSadomasochist violence he craved.

*** Abaddon and Megiddo are both named after biblical places of destruction, with the latter being believed by scholars to be the site of the FinalBattle between good and evil in Armageddon (fitting the namer, Walter Simmons', KnightTemplar). The former name also refers to an archangel of the bottomless pit (fitting the Zmeyevich's origin from [[SatanicArchetype Ghidorah]]).
*** Kazimir means "destroyer of peace". That's not foreboding at all.

* AffablyEvil: San-2/Youngest Brother is arguably the ZigZagged form. He's just as brutal as the other two heads in battle or when you're just in Ghidorah's way, and he views other living things which aren't a direct part of him as mere tools and toys, but he's the type of PsychopathicManchild who prefers playing lovingly with his toys and hates it when they get broken. [[https://hrodvitnon.tumblr.com/post/677379767724621824/ Word of God]] even comments that he tolerates the Many partly because he thinks Ghidorah can "fix" them.

** San-2/Youngest Brother, who is the result of San's original head following his mind transfer to the hybridized Vivienne re-forming San's personality and memories whilst it regenerated the rest of Ghidorah. As a result, San-2 lacks San's CharacterDevelopment that led to his HeelFaceTurn. Vivienne is able to tell the two San's apart when the evil one speaks to her in [[https://www.fanfiction.net/s/13357907/11 Chapter 11]], as San-2's voice sounds the same as when San first fused to her.

* AndIMustScream: Being frozen in the glacier and aware of the humans building a "cage" around it was this fate for Ichi/Eldest Brother in particular, and to a lesser extent Ni/Elder Brother. Both of them were pissed off and Ichi's BerserkButton was ''utterly'' pressed, yet they couldn't do a damn thing except mentally froth in rage and loathing until they were freed from the glacier.

* ItsPersonal: Ichi/Eldest Brother eating Vivienne alive and wanting San to grant her a FateWorseThanDeath was done because she hit his BerserkButton.

* LosingYourHead: In Chapter 17, [[spoiler:Ichi/Eldest Brother's head gets ripped off, and remains conscious and animate until it's executed by Monster X]].

* OhCrap: [[spoiler:Ichi/Eldest Brother has a small one in Chapter 17 when confronted with the idea that Ghidorah's enemies might actually be able to hunt down and destroy all the pieces of it after he dies, and thereby make his impending death become permanent]].

* TokenGoodTeammate: San-2/Youngest Brother, the same as San before the latter fused with Vivienne; is the least vicious of the three heads (though still not devoid of sadism), and he hates it when his brothers [[spoiler:damage their "toy" too much]].
