History Characters / AbraxasHrodvitnon

* RapeIsASpecialKindOfEvil: In [[https://www.fanfiction.net/s/13357907/16/Abraxas Chapter 16]], she finds herself sicker than ever before (and that is ''saying something'') when she realizes [[spoiler:Ghidorah intends to turn her into a BabyFactory for more monsters, with Ni/Elder Brother being more than happy to try exploiting this trope to break her mind]].

* PetTheDog: [[spoiler:San-2/Youngest Brother at one point fleetingly attempts to {{exploit}} this trope when telepathically contacting Vivienne; but like the real San before the latter's CharacterDevelopment, he regards Vivienne more as a beloved toy to be cared for, and he ferociously intervenes when Ni/Elder Brother's Many-avatar causes too much damage to Monster X]].

* HeroicLineage: Somewhat {{downplayed}} in that he's not actually a member of Monarch and is rather HeroicNeutral, but Dr. Brooks lampshades in Chapter 11 that he's studying marine history including Titans.

* FreakOut: Esfir's mind seems to be genuinely broken after her traumatic ordeal at the Basement Club's hands.

* ReluctantPsycho: ZigZagged. He doesn’t turn AxCrazy, but it becomes clear something’s wrong inside his noggin, and he’s torturously aware of it, pleading that he just wants to feel like himself again.

[[folder: The Many - UNMARKED SPOILERS AHEAD]]
!! In General

* SmugSnake: He doesn't seem to realize that both his brothers no longer consider him one of Ghidorah's heads after he's detached, and now he's just as much a shed skin to them as San is.

* ItIsDehumanizing: He's on the receiving end at times. Notably, Madison in Chapter 11 begins contemplating San as a he/him instead of an it when she observes San's protectiveness of Vivienne. [[spoiler:Ghidorah]] notably considers San an it and a thing due to its {{Dehumanization}}.

* MagicalDefibrillator: It's {{implied}} he gets a ShockAndAwe variation, when [[spoiler:his head is ripped off of Monster X and exposure to Vivienne's lightning makes it spring back to life, in Chapter 16]].

* NearDeathExperience: Besides the one he shares with Vivienne, in Chapter 16, [[spoiler:his head is ripped off of Monster X, and it's only a MagicalDefibrillator effect from Vivienne's powers that makes San's head animate in this state]].

* OOCIsSeriousBusiness: When pleading for Vivienne to trust him in Chapter 5, he calls her by her name instead of "sister" or "Bone Singer".

* {{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" despite them retaining their personalities; no longer be part of Ghidorah and inferior to Ghidorah]].

* FailedASpotCheck: When informed in Chapter 13 that multiple Titans are approaching Yonaguni, he doesn't realize ''what'' the hell that means he (currently on open waters) should be doing at this very moment.

* SympathyForTheDevil: He tries to [[ExploitedTrope exploit]] this by bringing up what happened to his daughter in Chapter 6. Vivienne doesn't fall for it, noting it doesn't in any way justify putting so many others through the same pain he experienced and worse. Vivienne suspects Jonah previously used this trick successfully on Emma Russell to turn her to the dark side.

* KickTheDog: It's pretty clear he's not just doing what Ichi/Eldest Brother wants and is enjoying torturing Monster X immensely for his own sadism in Chapter 16.

* {{Sadist}}: Although Ni/Elder Brother is usually more interested in killing than in making his prey die slowly, in Chapter 16, he demonstrates that he can be ''just'' as creative and vicious as Ichi/Eldest Brother if not even '''worse''' when he really takes an interest in torturing Vivienne.

* StalkerWithoutACrush: The "without a crush" part is ''horrifically'' ZigZagged by him. The author [[hrodvitnon.tumblr.com/post/648508725162803200/ confirmed]] Ni has a "murder boner" but not an actual boner for the idea of successfully driving Vivienne to psychosis following the VillainTakesAnInterest, and he seems ''really'' enthusiastic to {{exploit}} RapeIsASpecialKindOfEvil when psychologically torturing Monster X to that end.
* UnwittingPawn: {{Implied}}. He remains loyal to Ghidorah and insists he is still part of the Dragon, but his former brothers are just waiting for another Ni to regrow on their body and make it clear they no longer considered the Ni/Elder Brother who's detached from them their brother.

* GoodCounterpart: To Ghidorah; being a multi-headed Titan consisting of multiple "sibling" beings for either head, with similar powers and [[spoiler:a similar origin]] to the alien monster. But Vivienne and San are benevolent and want to live in peace, whereas Ghidorah is utterly sadistic and finds purpose in destruction. Vivienne specifically has an EvilCounterpart in Ghidorah's middle head, and San has one in Ni/Elder Brother's [[spoiler:Many shed skin]] (see their respective folders for details).

* HeroicRROD: The duo suffer this in [[https://www.fanfiction.net/s/13357907/6 Chapter 6]] when Vivienne overuses their powers in their first form, effectively microwaving their partly-human organs -- then again in Chapter 16, they suffer a more devastating [=RRoD=]. Their HealingFactor keeps them alive, but it's still ''not pretty''.

* HeroicRROD: The duo suffer this in [[https://www.fanfiction.net/s/13357907/6 Chapter 6]] when Vivienne overuses their powers in their first form, effectively microwaving their partly-human organs. Their HealingFactor keeps them alive, but it's still devastating and ''not pretty''.

* BigNo: When she freaks over [[spoiler:Susan Graham]]'s presence at Yonaguni in Chapter 15.

* IllKillYou: She mentally screams as much in graphic detail when she enters an UnstoppableRage in Chapter 13.

* OhCrap: Besides the example she shares with San (see above); she has one in Chapter 6 when she realizes the nature of Jonah's SanitySlippage, and in Chapter 16 when she realizes [[spoiler:Ghidorah has a BabyFactory plan for her]].

* RapeIsASpecialKindOfEvil: In [[https://www.fanfiction.net/s/13357907/16/Abraxas Chapter 16]], she finds herself sicker than ever before (and that is ''saying something'') when she realizes [[spoiler:Ni/Elder Brother intends to perform rape (or the closest allegory that their Titan bodies can physically make) on her and that Ghidorah is planning to turn her into a BabyFactory for more monsters]].

* TraumaCongaLine: My, oh, my. She gets EatenAlive and rendered OnlyMostlyDead (and is left with PTSD from this); she spends several months locked up underground in a space too small for her, with no track of time, transformed into a horrific part-Ghidorah monstrosity that’s in a state of chronic agony, and is inhumanely experimented on with various ammunitions to test her new HealingFactor; she finds out her surrogate father is dead (she takes this particularly hard)... [[spoiler:and when she finally escapes and gets somewhat better, she finds out Ghidorah is both BackFromTheDead and can use MindRape tactics on her via PsychicLink, attempting to stress her and drive her down a StartOfDarkness. And then there’s how her attempt at a reunion with her living mother goes]].

* BigBrotherInstinct: He displays this to a T when it comes to protecting Vivienne.

* GoodCounterpart: As of Chapter 16, he has a specific EvilCounterpart in Ni/Elder Brother. [[spoiler:Both are [[spoiler:formerly Ghidorah's heads which have split off and become "shed skins", but whereas San has Vivienne as his sister, loves her and has made a HeelFaceTurn; Ni is alone, he viciously exhibits a perverse narcissistic lust towards Vivienne when tormenting Monster X, and he's still loyal to Ghidorah]].

* LosingYourHead: His original head severed from Ghidorah retains his mind and some degree of consciousness. {{Downplayed}} in that while San's mind is aware inside the head, on the outside the head remains (''seemingly/mostly'') immobile.

* MagicalDefibrillator: [[spoiler:He gets a ShockAndAwe variation when his head is ripped off of Monster X and exposure to Vivienne's lightning makes it spring back to life, in Chapter 16]]. Likely justified by BizarreAlienBiology.

* IncestIsRelative: It's revealed in Chapter 16 that [[spoiler:Ghidorah intends to make Monster X a BabyFactory, despite admitting that it considers Vivienne its [[BrotherSisterIncest sister]] ''and'' its [[ParentalIncest daughter]]]].

* KickTheSonOfABitch: [[spoiler:All three of its minds deride Jonah as nothing more than a tool who served his purpose]].

* {{Narcissist}}: PlayedWith. Ghidorah's right and middle heads show several notable signs of narcissistic personality disorder. They consider themselves the only true god around compared to the Earth's native Titans, they obviously have ''zero'' compunctions about causing harm to others in order to further Ghidorah's own goals, they tend to reject or ignore or shift the blame for their own mistakes, and Ichi/Eldest Brother in particular is noted by Thor to be megalomaniacal. They don't really exhibit self-consciousness of how their lesser perceive them, though.

* PetTheDog: There's an attempt to [[ExploitedTrope exploit]] this regarding Ghidorah transforming Vivienne into Monster X. [[spoiler:San's EvilDoppelganger tries to paint San transforming Vivienne as him (the evil San specifically) caring for her]].

* VillainsNeverLie: Though that's not to say it isn't manipulative. See San's folder for more details.

----

* VillainousLegacy: Although he's dead after [[spoiler:Chapter 13]], the Many which he created remain a threat.

* PowerGlows: Ni/Elder Brother's [[spoiler:Many avatar]] does this as part of an intimidation display in Chapter 16.

* TheReasonYouSuckSpeech: He participates in the one Ichi/Eldest Brother and San-2/Youngest Brother give San (see Ghidorah's folder for details).

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) who is known to the other heads as "Youngest Brother"; and the "Eldest Brother" (the central head, Ichi) and "Eld'''er''' Brother/Young'''er''' Brother" (the right head, Ni).

* GoodCounterpart: To Ghidorah; being a multi-headed Titan consisting of multiple "sibling" beings for either head, with similar powers and [[spoiler:a similar origin]] to the alien monster. But Vivienne and San are benevolent and want to live in peace, whereas Ghidorah is utterly sadistic and finds purpose in destruction. Vivienne specifically has an EvilCounterpart in Ghidorah's middle head, and San has one in Ghidorah's right head (see their respective folders for details).

* NearDeathExperience: They seem to have one before Mothra revives them during their encounter in Chapter 7, similar to Madison's in the movie.

* ReluctantPsycho: It's heavily implied that Viv and San have the same instinct for inflicting violence that Ghidorah possessed, which exists on a neurally-ingrained level (fortunately, said instinct only manifests in Monster X if San or Vivienne are pushed too far). But more than that, Viv and San have issues dealing with Vivienne's untreated PTSD and both are saddened by it.

* HeroicBSOD: She's thrown into a gut-wrenchingly severe one after she discovers Serizawa is dead in [[https://www.fanfiction.net/s/13357907/4 Chapter 4]], coming pretty damn close to the DespairEventHorizon. She only comes out of it right when San hits his own [=BSoD=]...

* OhCrap: Besides the example she shares with San (see above); in Chapter 6, when she realizes the nature of Jonah's SanitySlippage.

* InSeriesNickname: He was given his name by Vivienne while she was monitoring Ghidorah in Antarctica -- he acknowledges it isn't his real name. He's also nicknamed Eddie the Head by Tejada. [[spoiler:Ghidorah and the Many refer to San as a "shed skin" after he’s merged with Vivienne]]. Though never stated, it can be inferred from how San refers to his brothers that Ichi and Ni would have probably called him "Youngest Brother" when he was still attached to them.
* ItIsDehumanizing: He's on the receiving end from humans at times. Notably, Madison in Chapter 11 begins contemplating San as a he/him instead of an it when she observes San's protectiveness of Vivienne.

* MagicDefibrillator: [[spoiler:He gets a ShockAndAwe variation when his head is ripped off of Monster X and exposure to Vivienne's lightning makes it spring back to life, in Chapter 16]]. Likely justified by BizarreAlienBiology.

* NearDeathExperience: Besides the one he shares with Vivienne, in Chapter 16, [[spoiler:his head is ripped off of Monster X, and it's only a MagicDefibrillator effect from Vivienne's powers that makes San's head animate in this state]].

** ** San himself gets one when Monster X is experiencing an [[spoiler:unpleasant face-to-face with]] and thus encounters Ghidorah in Chapter 16:

* SpeaksFluentAnimal: Naturally, being a Titan himself. [[InvertedTrope Inverted]] by his and Vivienne’s TwinTelepathy, which enables San to instantly pick up Vivienne’s vocabulary for communicating, and by Monster X’s ability to communicate in human vocalizations in its first form and via radio-waves in its second form.

* TwoFaced: He provides a non-villainous example in Chapter 3, when he manifests within the NightmareSequence as a duplicate of Vivienne's lost human form but with one side disfigured with Ghidorah-like HumanoidAbomination characteristics.
* VillainsNeverLie: Before his HeelFaceTurn at least. It turns out that he (and likely also his brothers) literally lack a concept of lying. [[https://hrodvitnon.tumblr.com/post/637226140951625728/ According to the author]], San regards the act of withholding information as a waste of thought.

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, nicknamed San-2 by a reviewer) and his "Eldest Brother" (the central head, Ichi) and "Elder Brother" (the right head, Ni).

* TheDeterminator: {{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 destroyed the Earth before it can move on to doing the same to another world.

* DynamicEntry: [[spoiler:Ni/Elder Brother, having apparently gained some kind of form independent of the other two heads, pulls one on an unprepared Monster X in Chapter 15]].

* IncestIsRelative: It's revealed in Chapter 16 that [[spoiler:Ni/Elder Brother is ''more than happy'' to inflict rape trauma on Monster X, and Ghidorah intends to make Monster X a BabyFactory, despite all three heads freely admitting that they consider Vivienne their [[BrotherSisterIncest sister]] ''and'' their [[ParentalIncest daughter]]]].

* PsychicLink: [[spoiler:Has one with Monster X, which it uses to try and BreakThemByTalking]].

* 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]].

!Alan Jonah's organization
[[folder: Alan Jonah]]
A former British Army colonel, who leads an underground paramilitary organization of mercenaries and eco-terrorists. He’s responsible for retrieving the severed Ghidorah head that Monster X is growing inside, and keeping Viv and San caged after their rebirth to further his misanthropic goals.

[[folder: The Many (In General) - UNMARKED SPOILERS AHEAD]]

* KillItWithFire: Rodan and Godzilla actively and respectively use their fiery {{Breath Weapon}}s to kill as much of the Many's infected tissue as possible.

* GoodCounterpart: To Ghidorah; being a multi-headed Titan consisting of multiple "sibling" beings for either head, with similar powers and [[spoiler:a similar origin]] to the alien monster. But Vivienne and San are benevolent and want to live in peace, whereas Ghidorah is utterly sadistic and finds purpose in destruction. Vivienne specifically is a Good Counterpart to Ghidorah's middle head (see her folder).

* DesperatelyCravesAffection / WellDoneSonGuy: He never got approval and affection from his brothers, and so he seeks these things from his new sister who he recognizes is nothing like them.

* TheReasonYouSuckSpeech: He angrily chews out [[spoiler:Susan Graham]] for reacting as she did to Monster X and [[spoiler:unwittingly hurting Vivienne]].

[[/folder]]

* BloodKnight: Discussed; in [[https://www.fanfiction.net/s/13357907/9 Chapter 9]], Vivienne blurts to Godzilla's face that he seems to enjoy a fight[[note]] which is a fair assumption, considering the 'smile'/'smirk' he bears at various points in the three {{Franchise/Monsterverse}} movies he's appeared in to date[[/note]], prompting him to draw the line between TranquilFury and TheBerserker for her.

* BloodKnight: Subverted. In [[https://www.fanfiction.net/s/13357907/9 Chapter 9]], Vivienne blurts to Godzilla's face that he seems to enjoy a fight[[note]] which is a fair assumption, considering the 'smile'/'smirk' he bears at various points in the three {{Franchise/Monsterverse}} movies he's appeared in to date[[/note]], prompting him to draw the line between TranquilFury and TheBerserker for her.

* GoodJawsEvilJaws: {{Inverted}} and ZigZagged, when they're in their toothy first form and their main enemies are asshole humans.

* JaggedMouth: In their first form, Viv and San have this trope's first and fourth types (hinting at animalistic nature and also a horrific-looking but ultimately benevolent creature). Vivienne's head has ingrown serrated teeth on either side of her jaws, whilst the author's art depicts San's head with a jagged mouth-shape.

* VillainTakesAnInterest: [[spoiler:It's pleased by Vivienne's capacity for UnstoppableRage as Monster X in Chapter 13]].

* TakeThat: Mariko having little tolerance for Mark's bullcrap (in contrast to the patient if exasperated way other Monarch characters treat him in the film and the fic), coupled with the SurvivorGuilt and YouShouldHaveDiedInstead he's received; seem like the author subtly criticizing ''King of the Monsters'' for making Vivienne die in a HeroicSacrifice that saved a character whom the author [[https://hrodvitnon.tumblr.com/post/624662973395386368/ found considerably less likable in the film]], without crossing into Ron the Death Eater territory. It's rather satisfying for readers who disliked Mark.

* FamedInStory: He's posthumously regarded the world over as something of a legend following his HeroicSuicide.

* PlatonicLifePartners: Besides her relationship with San (see above folder), her relationship with Dr. Serizawa beforehand was also this intimate.

* ReincarnationFriendship: A variation is hinted at. He seems particularly fascinated by Ren, his possible past life's son.

[[folder: Colonel Diane Foster]]
The experienced leader of Monarch's G-Team.

* ColonelBadass: Like in Film/MonsterVerse canon.
--->"''Dust this bitch!''"
* JurisdictionFriction: {{Downplayed}} in Chapter 7 during the joint operation with Team Mauzer. She decides regardless of Team Mauzer's orders, she'll make sure no-one but Monarch can get their hands on the Titan biological samples in the abandoned outpost.
* OhCrap: Besides the G-Team's MassOhCrap in Chapter 7; in Chapter 15, Foster has one when she realizes [[spoiler:the Many were diverting Godzilla and have knocked out Castle Bravo's communications]].
* ReasonableAuthorityFigure: Compared to Admiral Stenz, she learns from her mistakes and is open-minded enough that she decides no-one but Monarch should get their hands on Ghidorah's or Monster X's DNA.
--->"''The last time I didn't take a scientist seriously the world almost ended.''"
* ScientistVsSoldier: {{Defied}} and {{averted}} by her, as described under JurisdictionFriction.

[[folder: Lieutenant Ford Brody]]
A former EOD specialist in the U.S. military who transferred to Monarch's G-Team after the Mass Awakening. He's the husband of Elle Brody and the father of Sam Brody.

* TheBusCameBack: He's so far appeared twice in the story, although he's DemotedToExtra.
* DemotedToExtra: He appears a couple times in the story but is a supporting character, compared to his protagonist role in ''Film/Godzilla2014''.
* OhCrap: He and the G-Team have a MassOhCrap reaction in Chapter 7 when they become aware of Ghidorah's severed head. Ford specifically says, "Shit."

[[folder: Lauren Griffin]]
The G-Team's skilled pilot.

* OhCrap: She has one in Chapter 15 when she realizes the Many are headed towards [[spoiler:Castle Bravo]], where they can seize more Titan biomass for themselves.
--->"''Oh, shit.''"
* VitriolicBestBuds: With Vivienne (see her folder for details).

[[folder: Jackson Barnes]]
A G-Team soldier who participates in the joint rescue mission with Team Mauzer.

* PluckyComicRelief: The tradition from the film continues in Chapter 15.
* WhyDidItHaveToBeSnakes: PlayedForLaughs when Scylla shows up. Turns out Barnes is arachnophobic.

! Affiliates and Other Allies
[[folder: Madison Russell]]
The teenaged daughter of Mark Russell and the late Monarch operative-turned-eco terrorist Emma Russell. She had a close mother-daughter relationship with Vivienne before the events in Antarctica.

* BerserkButton: She immediately (and loudly) shuts Mariko down when the latter starts mentioning Emma in a positive light in Chapter 12, participating in the subsequent collective KirkSummation.
* DaddysGirl: She's apparently stuck with her father to make sure he doesn't go off the deep end again since the events in Boston, with her mother dead and [[ParentalSubstitute Vivienne]] having been believed dead since Antarctica.
* DidYouJustFlipOffCthulhu: She has no problem angrily accusing San to his face in [[https://www.fanfiction.net/s/13357907/8 Chapter 8]]. {{Justified}} as Madison was quite emotional at the time, San is attached to the same Titan body as Vivienne (who would never let any harm befall Madison), and Madison could quickly run indoors if need be; to say nothing of her DefiantToTheEnd close call in the movie.
* JustAKid: Mark says this about her almost word-for-word in Chapter 8 -- notably, he cuts her off from speaking when he says it -- prompting Ilene to point out that Madison has previously proven capable beyond her age.
* MisplacedRetribution: In Chapter 8, she angrily brings up Ghidorah chasing her in Boston, unaware that San only has the decapitated head's memories and genuinely doesn't remember what his AlternateSelf did. She also says that San killed Vivienne, though it was technically Ichi who did that while San just did the resurrecting and transforming parts.
* ShellShockedVeteran: She has some treated PTSD, not nearly as bad as Vivienne's untreated PTSD, from her encounters with Ghidorah and the events in Boston.

[[folder: Dr. Mark Russell]]
Madison's father, who suffers SurvivorGuilt after Vivienne Graham's apparent death in Antarctica which occurred partly due to her saving his life.

* IdiotBall: He handles it in Chapter 8 when [[spoiler:Monster X is being reborn]], asking why Monarch aren't trying to fence it with a containment field without realizing that'll have a negative effect due to the creature's TraumaCongaLine.
* JerkassRealization: The story basically confirms the film's implications that he had one about his past {{jerkass}} behavior.

* FreakOut: Something in Esfir seems to be genuinely broken after her traumatic ordeal at the Basement Clubs hands.

* LaserGuidedKarma: He has the hubris to mess with the remains of a highly-regenerative and omnicidal EldritchAbomination, [[spoiler:and he creates {{Artificial Zombie}}s from non-consenting human test subjects. He shares the latter fate, due to Ghidorah's remains inducing SanitySlippage and making him a pawn; to say nothing of his KarmicDeath]].

* GoodCounterpart: To Ghidorah; being a multi-headed Titan consisting of multiple "sibling" beings for either head, with similar powers [[spoiler:and a similar origin]] to the alien monster. But Vivienne and San are benevolent and want to live in peace, whereas Ghidorah is utterly sadistic and finds purpose in destruction. Vivienne specifically is a Good Counterpart to Ghidorah's middle head (see her folder).

* MultipleHeadCase / TwoBeingsOneBody: Vivienne's mind occupies the main head (formerly her human form's head before the transformation), while San occupies the secondary head; analogous to how Ghidorah's three heads shared a body. They're also able to switch (or forcibly seize) control of limbs or their whole body from each other.

* PintSizedPowerhouse: They're comparatively small by most Titans' standards, but ''Rodan'' is mesmerized by what they're capable of during an UnstoppableRage.

* VoicesAreMental: Very much [[DownplayedTrope downplayed]]. Both San and Vivienne's respective physical voices emitted from their respective mouths in their first forms are [[https://hrodvitnon.tumblr.com/post/185815052284/ described by the author]] as sounding like the Gravemind in ''Franchise/{{Halo}}''. After [[{{Metamorphosis}} metamorphosing]] into their second form, San and Vivienne communicate with humans via radio waves; San's radio voice is indicated to be the same as his mental voice, while Vivienne is able to produce words in her original human voice this way.

'''Vivienne''': ''No, no, no, no, no... I am like [Ichi], but I am not like [Ichi], in all the ways that matter. [Ichi/Ghidorah] will NEVER have me. I will NOT become like [Ichi/Ghidorah]!''

* {{Manchild}}: He takes his self-imposed duty of caring for his new sister seriously, but when he isn't angry or distressed, his personality can be quite childlike.

* TwoFaced: He provides a non-villainous example in Chapter 3, when he manifests within the NightmareSequence as a duplicate of Vivienne's form but with one side disfigured with Ghidorah-like HumanoidAbomination characteristics.

* AdaptationalBadass: Besides [[Characters/MonsterVerseKingGhidorah the points racked up by]] ''[[Characters/MonsterVerseKingGhidorah King of the Monsters]]'', [[spoiler:there's also the fact this story's version of Ghidorah 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]].

* EldritchAbomination: Whereas Ghidorah was portrayed in the film as a relatively mild example, in the fic, its psychic influence and its other capabilities makes it even more Lovecraftian.

* ReluctantPsycho: [[https://hrodvitnon.tumblr.com/post/645147573238333440/ According to the author]], Ghidorah was once this in the beginning. [[spoiler:Ghidorah's three brains had three words forcibly hardwired into them through indicated alien brain surgery, which consciously and unconsciously tormented the three heads ceaselessly and drove them to try again and again without success to make the ceaseless phrase stop by sating it. The author suggests these words probably faded to something like tinnitus later in Ghidorah's life]], but by then, Ghidorah's SlowlySlippingIntoEvil had come full circle.

* MasterOfYourDomain: {{Downplayed}}. His original decapitated head is able to both keep Vivienne alive in a coma inside itself and metamorphose her into an ArtificialHybrid, while also forming a second head on her which enables San's mind to transfer to her via BrainUploading.

* MasterOfYourDomain: {{Downplayed}}. 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 transformed to Ghidorah's desires, though not before she'd been partly digested by Ghidorah's stomach acids.

* ParentalAbandonment: It originally came from a clutch of eggs with no parents. Vivienne believes this indicates the species Ghidorah hailed from would leave their eggs to fend for themselves, similar to sea turtles.

* ParentalSubstitute: They seem to be juggling the duty of rearing Manda with Godzilla and Rodan after his birth. Vivienne also has more counts of being this trope (see her folder).

* CatLikeDragons: {{Downplayed}}. San at times produces vocalizations comparable to purring, particularly as a reassuring or affectionate gesture towards Vivienne.

* GeneticMemory: [[spoiler:It can regenerate all three heads' individual personalities and memories from just a single decapitated head]].

* OmnicidalManiac: The story expands on this. As San and San-2 explain, Ghidorah is ceaselessly killing all life besides itself that it can find in every corner of the universe it conquers, [[spoiler:repeating its {{revenge}} on the ones who turned Ichi, Ni and San into the three-headed monster in a vicious cycle,]] and it views life as temporary and finite insects who exist solely for the purpose of dying.

* PutThemAllOutOfMyMisery: [[spoiler:Its [[OmnicidalManiac Omnicidal Mania]] started as this, and it eventually decided it founded meaning in bringing oblivion in itself (see StrawNihilist)]].

* TurnedAgainstTheirMasters: [[spoiler:It's heavily implied Ghidorah's alien creators deliberately drove it to anger and psychosis to make it a more effective BioweaponBeast. Ghidorah destroyed what these aliens wanted it to, then it destroyed them as revenge for the trauma they caused it]].

* FirePurifies: Rodan and Godzilla actively and respectively use their fiery {{Breath Weapon}}s to kill as much of the Many's infected tissue as possible.

* KillItWithFire / NotQuiteDead: The Theta Team attempt using explosives on the Many's initial forms. It doesn't end them all.

* CatLikeDragons: {{Downplayed}}, but he produces a purr-like growl as an expression of affection or reassurance, which Vivienne compares to a cat purring to its kittens when she observes it.

* SlowlySlippingIntoEvil: As described by the author [[https://hrodvitnon.tumblr.com/post/645147573238333440/ here]] when discussing Ghidorah's {{Backstory}}, Ghidorah gradually suffered this until it became the sadistic OmnicidalManiac we all know it as.

-->"'''''YESSSS'''SSSSssssss''"

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

* BewareTheNiceOnes: Monster X overall embodies this trope like Ghidorah embodies the {{Sadist}}. See San and Vivienne's respective folders for details.

* AxCrazy / {{Sadist}}: The film already makes it clear that Ghidorah is a sadistic and immensely malevolent OmnicidalManiac, but this fic goes more into showing how depraved it's capable of being towards individuals in its cruelty (particularly the middle head), and also [[spoiler:[[BeingTorturedMakesYouEvil how it became that way]]]].

* BeingTorturedMakesYouEvil: [[spoiler:The traumatic procedures which turned the three brothers into Ghidorah drove Ichi to utter hatred of their creators, and Ni to perpetual anger, and it's what started their OmnicidalManiac campaign]].

* {{Sssssnaketalk}}: Only when the heads all say this word in unison:

* StrawNihilist: Seems to have shades of this, viewing all other life as temporary and worthless.

* TragicVillain: Besides how Ghidorah's bacstory makes it a WoobieDestroyerOfWorlds (see below), both [[https://hrodvitnon.tumblr.com/post/640060179124305920/ the author]] and a reviewer have noted that it's actually quite tragic that San-2 has the same potential for a HeelFaceTurn as Vivienne's San does, but remaining attached to Ichi and Ni prevents that from happening. Think Nebula in ''Film/AvengersEndgame''...

* VengeanceFeelsEmpty: PlayedWith. [[spoiler:It apparently at first sought meaning in killing the aliens who made it in {{revenge}}, but didn't find any]].

* WoobieDestroyerOfWorlds: Its {{backstory}} before coming to Earth is revealed in [[https://www.fanfiction.net/s/13357907/10 Chapter 10]]. [[spoiler:Ichi, Ni and San were born parentless in a harsh alien ecosystem where predators preyed on the infants of their kind, and Ichi had to teach his two brothers himself – but that's not where the tragedy comes in. The trio were captured and caged by a mysterious alien civilization, who forcibly transformed them into Ghidorah via torturous procedures which drove it to utter malevolence. Eventually, they TurnedAgainstTheirMasters (see above), and now they're repeating their revenge again and again wherever they find life in the universe that even reminds them of Ghidorah's creators, in a vicious cycle]].

* LaserGuidedKarma: he has the hubris to mess with the remains of a highly-regenerative and omnicidal EldritchAbomination, [[spoiler:and he creates {{Artificial Zombie}}s from non-consenting human test subjects. He shares the latter fate, due to Ghidorah's remains inducing SanitySlippage and making him a pawn; to say nothing of his KarmicDeath]].

* MultipleHeadCase / [[TwoBeingsOneBody Three Beings, One Body]]: 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. [[spoiler:It's heavily implied in Chapter 10 that Ichi, Ni and San were originally single-headed creatures born from the same clutch of eggs, and the brothers were turned into the three-headed destroyer by alien experiments]].

* OCStandIn: In the Film/MonsterVerse canon she was [[TheGhost only mentioned]] in [[AllThereInTheManual Manual]] materials.

* OCStandIn: The ''Abraxas'' version of Ren was introduced when the character was still TheGhost in Film/MonsterVerse canon.

* TheReasonYouSuckSpeech: He angrily chews out [[spoiler:Susan Graham]] for reacting as they did to Monster X and [[spoiler:unwittingly hurting Vivienne]].

* MetamorphosisMonster: Has gone through two different forms so far over the course of the story, and [[https://hrodvitnon.tumblr.com/post/616668234453794816/ the author has indicated they're due one more transformation before reaching their final form]].

* TheReasonYouSuckSpeech: She [[spoiler:gets one from San (see his folder)[[note]]Listed there to avoid spoilers[[/note]]]]

* BreathWeapon: He can spit fireballs from his maw.

* BrownNote: The decapitated head's psychic influence seems to cause this, driving to suicide those who don't suffer MoreThanMindControl corruption.

* TheCorruption / MoreThanMindControl: Members of Jonah's organization who are touched by the Ghidorah-head's influence either kill themselves or display signs of this, with Jonah believing himself enlightened during his SanitySlippage.

* DirtyCoward: ZigZagged and, depending on your point of view, subverted. He initially says he's scared to confront Vivienne and thus refuses to see her despite his obvious wish to, though he later sees her in person and lets out everything he wants to say to her.

* LaserGuidedKarma: he has the hubris to mess with the remains of a highly-regenerative and omnicidal EldritchAbomination, [[spoiler:and he creates {{Artificial Zombie}}s from non-consenting human test subjects. He shares the latter fate, due to Ghidorah's remains using MoreThanMindControl to make him a pawn; to say nothing of his KarmicDeath]].

* MoreThanMindControl: He's on the receiving end due to the decapitated Ghidorah head's psychic influence, [[spoiler:causing him to aid the Many's propagation and eventually become part of them]].

* SanitySlippage: Due to the severed Ghidorah-head's borderline-MindRape [[MoreThanMindControl influence]]. First he has an AxCrazy episode, then he becomes more unkempt and acts eerily like he's been spending too much time around [[MassEffect/MassEffectRaceTropes Reaper tech]]. [[spoiler:Finally, he becomes an insane, fanatical part of the Many]].
* SmugSnake: He thinks he can psychologically break down Monster X as he did Emma Russell, and there's him holding the VillainBall. He's also too arrogant to realize he's experiencing an induced SanitySlippage courtesy of the Ghidorah head, instead [[MoreThanMindControl thinking he's been enlightened]].

** His whole SanitySlippage can be seen as a Villainous Breakdown that's forced on him by MindRape and MoreThanMindControl, up to his death.

* WasOnceAMan: They’re TheAssimilator, and initial {{Artificial Zombie}}s were created by Jonah’s organization fusing Ghidorah’s experimented-on DNA to human hosts.

A prominent Monarch scientist who had a close relationship with Dr. Serizawa. She was EatenAlive by Ghidorah (Ichi/Eldest Brother) in Antarctica, before being stored inside San's head to be revived and transformed; forming San's new sister as part of Monster X. She functions as the main head.

* BackFromTheDead: She technically was temporarily dead after being EatenAlive by Ichi/Eldest Brother, before being ejected into San's neck where she was forcefully revived and kept alive in a comatose state. Apparently, [[ArtisticLicenseBiology her brain activity temporarily ceased before her faculties were restored intact]].
