9!!General
10!!!'''Scientific name:''' ''Titanus Abraxas''
11A two-headed, half-human and half-Ghidorah "chimera" Titan, created by Ghidorah's severed head regenerating and transforming Vivienne Graham's body inside itself and transferring the head's (San's) own consciousness to her body's new second brain. It possesses bio-electrical abilities which differ somewhat from Ghidorah's and is incapable of flight.
12
13[[folder:Tropes #-H]]
14* EleventhHourSuperpower: Their final form grants them a few new abilities and an instance of RemovedAchillesHeel in time for the FinalBattle.
15* AdaptationalAttractiveness: {{Downplayed}}. Their second form is a bit less demonic-looking than the [[Film/GodzillaFinalWars original incarnation of Monster X]], and it's outright described by Mariko as beautiful. [[spoiler:The trope gets lessened even more by their final form]].
16* AdaptationalHeroism: This fic's incarnation of Monster X fills this trope in relation to the original Toho incarnation.
17* AdaptationalSuperpowerChange: They seem to lack the original incarnation's Antigravity Beams and telekinesis, instead displaying a fresh alternative set of powers with a similarly electrical nature.
18* AdaptationalWimp: Being TheProtagonist with AdaptationalHeroism, this version of Monster X is less OP than the original villainous incarnation. Whereas the Toho version of Monster X was powerful and formidable enough to be a credible rival to Godzilla, this version would implicitly likely lose if it fought Godzilla seriously. There's also the AdaptationalSuperpowerChange.
19* AdaptationNameChange: {{Downplayed}}. Due to the DecompositeCharacter, Monster X's non-designation name is changed from Keizer Ghidorah to Abraxas.
20* AffectionateGestureToTheHead: Including AnywhereButTheirLips, a HeadbuttOfLove, and coiling their necks around each-other in a form of embrace. They also nuzzle Manda.
21* AlienBlood: The same as Ghidorah's.
22* AndroclesLion: {{Inverted}}. Godzilla says that if a Titan protects humans as if they're their own, then humans will return the favor to the Titan in its own time of need. [[spoiler:Monster X later passes the same lesson on to Manda]].
23* AndThisIsFor: They say this in their final form before they begin [[VampiricDraining sucking the life out of]] [[spoiler:[=MaNi=]/Elder Brother]].
24--->"''This is for thinking you can hurt my little boy.''"
25* AnkleDrag: They pull a particularly nasty variation on the MookLieutenant they kill in Chapter 4 – specifically, San ''hooks a claw into their leg'' and drags them back.
26* AntiAntichrist: It's sort of an offspring of Ghidorah, a SatanicArchetype (the Many even call it Child of the World Eater); and [[spoiler:Ghidorah's regenerating minds]] are attempting to break Viv and San [[BreakThemByTalking via talking]] [[spoiler:and want Vivienne to become Ghidorah's fourth head]], whilst Viv and San seek to remain aligned with Earth's Titans against the threat.
27* AnyLastWords: They ask [[spoiler:Ichi/Eldest Brother]] as much before destroying his [[spoiler:head]] in Chapter 17:
28--->"''It's customary to have a choice of last words, you know.''"
29* AnywhereButTheirLips: Vivienne and San have each at one point given the other a kiss on the forehead as an affectionate gesture and a way of comforting their sibling.
30* AppropriatedAppellation: According to [[https://hrodvitnon.tumblr.com/post/694483325970153472/ the author]], Monster X has likely made some "edgelord" jokes in stride, in response to humans making "edgelord" jokes toward them up to and including an "edgelord" nickname. See San's folder for another example.
31* AnArmAndALeg: [[spoiler:Subverted]]. It looks like they're gonna lose an arm in Chapter 13 [[spoiler:when the Many rips off their left arm. The damage isn't lasting]].
32* ArtificialHybrid: Monster X's body was formed by Ghidorah's severed head regenerating and altering Vivienne's body inside itself, before the first hybridised form was re-birthed from the severed head.
33* AwesomeButImpractical: Their MultipleHeadCase is arguably this, since unlike Ghidorah they can't [[spoiler:regrow a decapitated head, and therefore if one of their heads is fully destroyed or can't be reattached then one of the siblings will be lost forever]]. This gets fixed in their final form.
34* BadassBoast:
35** Its [[spoiler:two partly-merged minds]] have the below to say to [[spoiler:Ichi/Eldest Brother]] in Chapter 17. See Vivienne's folder for another example.
36--->'''[[spoiler:Ichi]]: HA. YOU ARE MORE LIKE ME THAN YOU CARE TO ADMIT.'''\
37'''Monster X:''' Comes with the name. I am [[MeaningfulName Abraxas]]. I can be good... and I can be a terrible, necessary evil.
38** According to [[https://hrodvitnon.tumblr.com/post/694483325970153472/ Word of God]], InUniverse, Monster X can intimidate several Titans using "stock edgelord phrases" – "''YOUR DEATH COMES''"/"''YOUR ANGEL OF DEATH AWAITS''" – that Monster X originally began using as a corny joke towards humans (since Titans don't find the phrases nearly as corny as a modern human would).
39* BadPowersGoodPeople: Mothra states in Chapter 9 that Monster X has inherited Ghidorah’s powers but that doesn’t make Vivienne accountable for Ghidorah’s atrocities.
40* BarehandedBladeBlock: In their final form, they block a strike from [=MaNi=]/Elder Brother's spiked appendage and [[spoiler:shatter the arm it's attached to]], by lifting their arm and striking out with electrical SuperSpeed.
41* BelligerentSexualTension: Viv and San show definite signs of this with Rodan later in the story; with Rodan's desire to fight them again and San reciprocating the feeling, and Vivienne growing fond of Rodan whilst still regarding him as a jackass. [[spoiler:The Timeline reveals that they've reportedly become mates by 2022]].
42* BenevolentMonsters: They're this to humans, being gigantic and terrifying-looking, but highly benign and even benevolent to humans who haven't crossed them. This is particularly prominent when [[PlayedForLaughs they try asking terrified civilians for directions at one point]].
43* BewareTheNiceOnes: Monster X overall embodies this trope like Ghidorah embodies the {{Sadist}} -- probably helping it, it's implied that both heads have to some degree inherited Ghidorah's violent AxCrazy neurons. See San and Vivienne's respective folders for details.
44---> '''Tejada''': "[…] ''for god's sake, ''do not make her angry''. ''Do not fucking piss her off''. Understand? We made her a demon.''"
45* [[BigBrotherInstinct Big Brother/Sister Instinct]]: San displays this to a T when it comes to protecting Vivienne, and Vivienne eventually comes to wholly reciprocate it when San's the one in danger.
46* [[BigBrotherMentor Big Brother/Sister Mentor]]: Monster X is an interesting two-way example. Vivienne teaches San about humanity and mythology, while San in turn teaches her how to survive as a Titan, to say nothing of the emotional support they mutually provide each-other.
47* BioluminescenceIsCool: Its VolcanicVeins are interpreted by certain Titans as communication like Godzilla's.
48* BizarreAlienBiology: Possesses two hearts, a third lung (acting as an "oxygen bladder" when the main lungs are too damaged to work), a "pre-stomach" organ which is thought to filter out food toxins, numerous glands of indeterminate function. They also have traces of aurum (gold) in their defective first form's skin and bones, which turns into argentum (silver) after their second transformation, for the purpose of conducting their bio-electricity. Their second form has a mix of leathery skin and bony exoskeletal armor.
49* BizarreAlienSenses: San can perceive electrical fields and currents in his field of vision. He can extend this sense to Vivienne via their neural link if they wish it.
50* BloodFromEveryOrifice: Viv and San's heads both start bleeding from their noses, mouths and eyes when [[spoiler:Ghidorah violently makes psychic contact]], in Chapter 14.
51* BodyHorror: In its first form, where it's in a constant state of pain, has ingrown extra fangs along the jaws; and a horrifically extreme case of ''Fibrodysplasia ossificans progressiva'' due to their {{Healing Factor}}'s defect, making it very difficult for the duo to move certain joints without risking breaking their bones.
52* BreakThemByTalking: They successfully get under [[spoiler:Ichi/Eldest Brother]]'s skin by giving him the idea that perhaps he'll die permanently when they kill him, [[spoiler:and in doing so they avenge all the BreakThemByTalking that Ghidorah gleefully conducted on them]].
53* BrownNote: Very {{downplayed}}. Monster X doesn't seem to have any detrimental effects on the minds of humans who come into contact with them. [[https://hrodvitnon.tumblr.com/post/691622393957023744/ Word of God]] says that Monster X has a much more "passive, mild" Brown Note, if any at all; unlike Ghidorah and Thor.
54* BruiserWithASoftCenter: They eventually become this. Viv and San are a highly-powerful Titan in possession of all Ghidorah's ferocity but none of its malice or AxCrazy, they're protective of humans even more than most Protector Titans, and they're very tentative towards Manda and their human loved ones.
55* BurnScarsBurningPowers: Electricity-based rather than fire-based powers, but otherwise this trope applies to Viv and San's first hybridized form, which is covered in keloid-like scars.
56* ChargedAttack: They can perform the "Hold" type to release massive bursts of electrical power, but both times they've done this, it's carried the risk of severe HeroicRROD.
57* ChestBurster: [[spoiler:Once they're awakened inside Ghidorah during their final {{Metamorphosis}}, they violently rip their way out of the evil monster]].
58* ColdBloodedTorture: The inhumane experiments which Jonah and his paramilitary perform on them are both the MadScientist and BeingTorturedMakesYouEvil variety. In Chapter 16, they're subject to this from [[spoiler:Ghidorah and [=MaNi=]/Elder Brother]].
59* CombatPragmatist: {{Averted}}. During Monster X's fight with [[spoiler:Rodan]], they deliberately avoid using more than four limbs at all to keep the fight even.
60* ComicBookFantasyCasting: Aside from San's mental voice (see his folder), in its first form, Monster X's physical voice [[https://hrodvitnon.tumblr.com/post/185815052284/ apparently sounds like]] the [[Characters/HaloOther Gravemind]] from ''Franchise/{{Halo}}''.
61* ContrastingSequelMainCharacter:
62** To Godzilla. Half of Monster X is genetically Godzilla's ArchEnemy, Monster X's PowerGlows is crimson compared to Godzilla's blue PowerGlows, and Monster X is a land-bound Titan [[spoiler:and then a GiantFlyer]] instead of a swimmer. Whereas Godzilla is the LastOfHisKind who was born millions of years ago, Monster X is a newly-formed ArtificialHybrid; whereas Godzilla is a DestructiveSaviour, Monster X goes more out of their way to limit destruction to human settlements when they can; and Godzilla is TheStoic, whereas Viv and San are {{Reluctant Psycho}}s grappling with Vivienne's PTSD and with Ghidorah-derived impulses.
63** And to the previous [=MonsterVerse=] movies' human protagonists, [[Film/Godzilla2014 Joe and Ford Brody]] and [[Film/GodzillaKingOfTheMonsters2019 Mark Russell]]. The focus of the aforementioned protagonists' screentime was repairing old, frayed familial bonds and coming to the rescue of family across continental borders, and most of them had an ex-wife or a [[TheLostLenore Lost Lenore]] respectively. Viv and San's character journey, on the other hand, is about them forming a completely new familial bond with each-other (and then with Manda) after they've been brought together, they show signs of forming a new FantasticRomance with [[spoiler:Rodan]], and rather than trying to get back to their loved ones they're actively defending them on the field.
64** See Viv and San's respective folders below for more individual details.
65* ConvergingStreamWeapon: In their final form, they can fire [[spoiler:Destroyed Thunder beams from either eye]] which form a single, concentrated beam of electrical energy.
66* CounterAttack: At one point, they wait for [=MaNi=]/Elder Brother to lunge at them, and they sidestep around him and stab two stalactites into his throat. See San's folder for another example.
67* CoveredWithScars: Viv and San's first form is covered thoroughly in horrific keloid scars, emphasizing Vivienne's breaking trauma.
68* CowardiceCallout: Both Viv and San more than once call Jonah out for the DirtyCoward he is at heart, after they learn [[spoiler:the truth behind Asher's death and]] about how Emma escaped from him.
69* CurbStompCushion: They get this in Chapter 16 when [[spoiler:suffering ColdBloodedTorture by [=MaNi=]/Elder Brother. Vivienne is able to save San from being killed and do some damage to [=MaNi=], but Ghidorah and the Many are still present around them, before the HeroicRROD hits]].
70* DarkIsNotEvil: It has dark gray, leathery skin after its second {{Metamorphosis}}.
71* DeadpanSnarker: Both of them have moments of sarcasm, though San is less prone to it due to his [[BlueAndOrangeMorality alien mindset]], though he's still capable of joking around.
72* DeathGlare: Vivienne and San both hand out a few of these.
73* DecompositeCharacter: In this continuity, Keizer Ghidorah is a separate creature from Monster X instead of being its OneWingedAngel.
74* DeepSleep: Viv and San seem to fall into this in the aftermath of a HeroicRROD, and it's implied they might've entered a NearDeathExperience during it. [[spoiler:They experience a much more peaceful Deep Sleep after the battle against Keizer Ghidorah]].
75* DestructiveSaviour: {{Averted}}. Due to Vivienne's feelings, she and San notably go more out of their way than even heroic Titans do to try and keep Titan battles from spilling into populated areas; a polar opposite to Ghidorah's pure, senseless sadism.
76* DisapprovingLook: They both try to give [[spoiler:Manda]] one when the latter wanders off.
77* DiseaseBleach: Non-canonically, the author [[https://hrodvitnon.tumblr.com/post/624119853506232320/ imagined]] when designing Monster X's Gijinka that if it were humanoid, it would have white hair due to the severe stress of the first {{Metamorphosis}} which formed it, an idea which she implemented in [[https://hrodvitnon.tumblr.com/post/694341867251302400/ this non-canon drabble]].
78* DivingSave: They pull one to save [[spoiler:Mothra]] from being crushed by [[spoiler:Keizer Ghidorah]] in Chapter 17.
79* DontFearTheReaper: A metaphorical case. [[spoiler:Viv and San's final form looks like the Grim Reaper of {{Kaiju}}, and they comfort Susan and are with her when she dies. The symbolism is made all the more appropriate by the fact Susan outright rejects the chance to become immortal]]. Poetically, Monster X sings the lyrics of "[[Music/BlueOysterCult Don't Fear the Reaper]]" in Chapter 17. They're even classified uniquely as an Executioner Titan instead of a Protector or Destroyer.
80* DraconicHumanoid: [[spoiler:Their final form is upright-standing with a roughly humanoid build, and besides the PrehensileTail has retractable bat-like wings on the back for flying]].
81* DramaPreservingHandicap: For the first several chapters, their PowerIncontinence feeds their problems with escaping their imprisonment.
82* DualityMotif: In their [[spoiler:single-headed]] final form, [[spoiler:they have different colored eyes, with either eye retaining either half's eye color]].
83* ElementalAbsorption: Like Ghidorah, Viv and San can absorb electrical energy from both manmade and natural sources to fuel their own electrical powers and strengthen themselves.
84* EmergencyTransformation: [[spoiler:Ghidorah]] inflicts a third and final {{Metamorphosis}} on San and Vivienne in [[https://www.fanfiction.net/s/13357907/16/ Chapter 16]], in order to keep Vivienne alive and her mind intact after a HeroicRROD [[spoiler:tears Monster X apart]].
85%%* EnemyMine: DownplayedTrope
86* EnergyAbsorption: They can absorb electrical energy to feed and strengthen their attacks.
87* EurekaMoment: They have one in Chapter 17, realizing [[spoiler:the key to successfully mastering their violent fits]].
88* ExtremeMeleeRevenge: Besides the example listed under San's folder; [[spoiler:Monster X is capable of exhibiting a Ghidorah-like sadism but reserving it specifically for those they've marked as enemies]].
89* EyeAwaken: Besides the examples under San's folder, when he and Vivienne are reborn in their final form, their [[spoiler:new shared single head]] pulls this trope off rather dramatically.
90* EyeBeams: [[spoiler:In their final form, Viv and San gain the ability to fire Gravity Beam-like Destroyed Thunder from their eyes, an ability which the [[Film/GodzillaFinalWars original Toho incarnation of Monster X]] possessed]].
91* EyeColourChange: Besides Vivienne's example (see below), this trope is PlayedWith regarding Monster X's final form. [[spoiler:When one of Monster X's two personalities is more in immediate control than the other, their heterochromic eyes become a single color (hazel green for Vivienne, red for San)]].
92* EyesAreMental: Both heads' original forms' respective eye colors are retained. [[spoiler:In their single-headed final form, they have [[DualityMotif heterochromic eyes]] containing both their original eye colors -- ''Fanfic/AbraxasEmptyFullness'' demonstrates the author's [[https://hrodvitnon.tumblr.com/post/662161939449905152/ previous]] [[https://hrodvitnon.tumblr.com/post/686977321772646400/ statements]] that the heterochromia disappears when only one personality is active[[note]]Both eyes are hazel when only Vivienne is in control, red when only San is in control[[/note]]]].
93* EyeScream: They suffer bleeding from their eyes as part of the BloodFromEveryOrifice that ensues during a psychically-induced seizure, in Chapter 14. See Vivienne's folder for more examples.
94* FacialHorror: In their first form; Vivienne's head is rather skull-like with ingrown fangs, while San's head at first doesn't have a mouth in addition to looking under-developed.
95* FantasticRomance: [[spoiler:According to the Timeline, Monster X has reportedly become mates with Rodan by 2022, which was only possible due to Vivienne getting turned into a Titan and San fusing with her]].
96* [[FireForgedFriends Fire-Forged Siblings]]: They go through months of ''hell'' together before they form a mutual emotional bond, rendering them as inseparable mentally as they are [[TwoBeingsOneBody physically]].
97* FlawedPrototype:
98** Comparative to their later forms, Viv and San's first hybridized form is defective and severely crippled, suffering PowerIncontinence and movement-limiting BodyHorror. According to Word of God [[https://archiveofourown.org/comments/247897682 here]] and [[https://hrodvitnon.tumblr.com/post/692341609101148160/ here]], the defects likely occurred due to San not understanding how human bodies biologically work and due to him not giving the hybrid a long enough gestation period.
99** [[https://hrodvitnon.tumblr.com/post/689311522082668544/ Word of God]] also describes Monster X as a prototype to the Many ("the First of Many"). Unlike the Many, Viv and San's first form's BodyHorror is ''crippling'' and it doesn't have any ability to reshape itself for mobility. Monster X is also a lot less [[spoiler:subservient to Ghidorah's wishes of them]] than the Many are.
100* FlipPersonality: Viv and San do a downplayed form of this in their first form before San's head gains its own mouth, taking turns with control of Vivienne's mouth when they both want to physically speak. [[spoiler:Played straighter in their MentalFusion final form, where their two personalities can split out of their merged state and take turns individually speaking to each-other or to someone else when they want]].
101* FlippingTheBird: Vivienne mainly does this, but San is picking up on it and humorously mistakes it for a standard way of greeting.
102* FoeTossingCharge: They bulldoze through Jonah's mercenaries pretty much by trying to ''flee'' in Chapter 2.
103* {{Foil}}: Besides being a GoodCounterpart to Ghidorah, and besides Viv and San's individual cases (see below):
104** Monster X overall is this to Godzilla. Both of them are reptilian Titans who are ultimately protective of the world, but Godzilla is positively ancient and experienced whereas Monster X is essentially a newborn. Godzilla is the King of the Monsters, whereas Monster X is essentially a pup among the Titans; and whereas Godzilla is a MessianicArchetype, Monster X is the AntiAntichrist.
105** Also to Manda. Monster X is an ArtificialHybrid created by [[SatanicArchetype Ghidorah]] (and half of them is a BackFromTheDead former-human with their memories intact) with a ton of trauma, whereas Manda is a possible [[spoiler:{{Reincarnation}} of a former-human as a divine reward]] and is innocent.
106* ForcedToWatch: [[spoiler:Ichi/Eldest Brother and Ni/Elder Brother]] are happy to let Monster X helplessly watch [[spoiler:Thor being assimilated]] in Chapter 17. See Vivienne's folder for another example.
107* FriendlyRivalry: {{Downplayed}}, but they seem to have eventually formed one with Rodan, dueling him for the physical training and the fun of it.
108* FusionDance: Viv and San are TwoBeingsOneBody from the get-go. However, [[spoiler:in their single-headed final form they also partly become The Composite with a MentalFusion]].
109* GenderBender: A TwoBeingsOneBody Titan consisting of a "male" alien and a formerly-human female. Characters primarily refer to Monster X generally as female (likely due to Vivienne being the "main" head), but the author [[https://hrodvitnon.tumblr.com/post/638048240187621376/ confirmed]] that Monster X is biologically hermaphroditic, and she furthermore suggested that its sex organs cyclically metamorphose between male and female.
110* GenerationalMagicDecline: {{Downplayed|Trope}}. [[https://hrodvitnon.tumblr.com/post/680115466430283776/ Word of God]] suggests that Monster X is "half-Alpha" due to being a hybrid of a human and an established Alpha Titan, and that their Alpha Call equivalent therefore mostly likely translates to a demand for a fight instead of a dominating sound.
111* GentleGiant: A monstrous Titan feared by humans not least for its resemblance/relation to Ghidorah, who is actually a case of BewareTheNiceOnes and is very friendly towards Vivienne’s human friends.
112* GiantFlyer: [[spoiler:It becomes this in its final form, gaining retractable wings. [[https://hrodvitnon.tumblr.com/post/672405103227060224/ Word of God]] says their electrical abilities enable them to use the Earth's electrical field to fly in ways that not even Rodan can]].
113* AGirlAndHerX: PlayedWith. If the girl and the X are TwoBeingsOneBody, then Viv and San definitely have shades of this. Vivienne is already a grown woman before being eaten by Ghidorah and turned into San's new sister, and Viv and San's subsequent bonding puts Vivienne on the path to mental recovery from severe PTSD.
114* GlowingEyesOfDoom / RedEyesTakeWarning: In Chapter 4, their eyes glow a burning red when San takes control and brutally slaughters Jonah's mercenaries. It happens again in their final form during the FinalBattle.
115* GoodColorsEvilColors: Besides the DarkIsNotEvil and RedIsHeroic, their second form has visible traces of [[SilverBullet silver]] in its bone armor, in contrast to Ghidorah's and the Many's gold.
116* GoodCounterpart: To Ghidorah; being a multi-headed Titan consisting of multiple "sibling" beings for either head, with similar powers and [[spoiler:a very similar origin]] to the alien monster which created it; but Vivienne and San are benevolent and want to live in peace, whereas Ghidorah is utterly sadistic and finds purpose in destruction. Furthermore, both monsters were on the receiving end of attempts [[spoiler:by their respective creators/transformers/originators and jailers]] to [[InvokedTrope invoke]] BeingTorturedMakesYouEvil. Both Monster X and Ghidorah notably lack the terrestrial Titans' HumansAreInsects attitude, but their interactions with and attitudes towards humanity are completely opposite. Although both Titans can communicate psychically, Monster X's use of vocalizations (with Titans) and EVP (with humans) is much less invasive than Ghidorah's {{telepathy}}. Ichi, Ni and San were born siblings before they became the Destroyer of Worlds, whereas Viv and San ''became'' a SiblingTeam. Ghidorah views its lost heads and body parts as replaceable, whereas Monster X [[spoiler:does ''not'']]. Additionally worth noting; Vivienne specifically has an Evil Counterpart in Ghidorah's middle head, and San has one in [=MaNi=]/Elder Brother (see their respective folders [[Characters/AbraxasHrodvitnonTitansAndOtherCreatures here]] for details).
117* GoodIsNotSoft: They're mostly kind and affectionate, and Vivienne's influence on San means they go more out of their way than even Godzilla or Mothra would to minimize innocent human casualties. On the other hand, true to their Ghidorah heritage, they can be as vicious as Ghidorah when [[PayEvilUntoEvil paying evil unto evil]] and/or when sufficiently pissed off at an enemy.
118* GoodLipsEvilJaws: {{Inverted}} and ZigZagged, when they're in their toothy first form and their main enemies are asshole humans.
119* GoodThingYouCanHeal: They have a notably unearthly HealingFactor, and over the story they endure and (usually) bounce back from damage that would cripple most terrestrial Titans for life if not put them down altogether, including but not limited to dismemberment.
120* GoThroughMe: The nature of their fight against the Many at Yonaguni, preventing them from reaching the town of Higawa.
121* GrinOfAudacity: They have a couple when about to try one-upping [[spoiler:Keizer Ghidorah]], and a few more whilst duelling [[spoiler:Rodan]], [[spoiler:in their final form]]. See San's folder for another example.
122* HannibalLecture: In Chapter 6, Jonah's attempt to get to the captive Monster X after he's been attempting to break them ends up being this once they get under ''his'' skin with the death of Ash, proceeding to give him a full exchange involving a ReasonYouSuckSpeech.
123* HeadbuttOfLove: Viv and San have one when San is attempting to comfort Vivienne in Chapter 11. They also more than once brush the other's horns and jawline as an affectionate gesture.
124* HealingFactor: Viv and San post-fusion have inherited/retained Ghidorah's regenerative abilities, but in their first hybridized form, a defect results in extra bone matter growing in place of lost flesh, which is gradually immobilizing Viv and San's body parts and makes it extremely difficult for them to move without breaking bones. The defect is fixed during their [[EmergencyTransformation Emergency]] {{Metamorphosis}}, with [[https://hrodvitnon.tumblr.com/post/690310730958962688/ Word of God]] noting that the defect was "patched out" at the price of making Viv and San [[spoiler:less able to replace lost limbs or heads]].
125* HealItWithFire: Rodan's fire cauterizes some of their injuries at the Yonaguni battle, in Chapter 13.
126* HeIsNotMyBoyfriend: {{Downplayed}}. They take notice when someone first hints to them that people are [[ShipperOnDeck shipping them with Rodan]].
127* HeldGaze:
128** Viv and San hold each-other's gazes in the [[PlatonicLifePartners Platonic]] form of this trope when they concile with each-other and when Vivienne is comforting San, in Chapter 5.
129** Mothra also gives them a couple such gaze-locking looks to try and comfort them, one of which gives Viv and San a brief vision.
130** The Antagonistic version occurs when Monster X in their final form stares down the enemy in Chapter 17. [[spoiler:Specifically, they stare down all three of the heads of Ghidorah, who has caused both halves of Monster X so much pain and suffering]].
131** In Chapter 17, Thor locks gazes with Monster X as a way of reassuring them. [[spoiler:This comes amid Thor's last stand against Keizer Ghidorah]].
132** In the fourth ''Fanfic/AbraxasEmptyFullness'' one-shot (confirmed by the author to be non-canon), Monster X shares several Romantic held gazes with Dr. Ling when old feelings between Ling and Vivienne are stirring up and when San is, according to the author, developing a slight crush on Ling.
133** See the below folders for individual examples.
134* {{Hermaphrodite}}: Monster X consists of two entities, one originally male (San) and the other originally female (Vivienne), [[TwoBeingsOneBody sharing a single body]]. DNA analysis by Monarch confirms that Monster X has both male and female chromosomes from either half, and the author [[https://hrodvitnon.tumblr.com/post/638048240187621376/ here]] elaborated on Monster X's hermaphroditic anatomy.
135* HeroicBuild: The [[ImageLinks/AbraxasHrodvitnon author's artwork]] depicts their second and final forms with brawny limbs and a toned, muscular chest.
136* HeroicNeutral: At first San and Vivienne are this, as their main objective is to escape their imprisonment to freedom.
137* HeroicRROD: The duo suffers 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 in Chapter 16, they suffer a more devastating [=RRoD=]. Their HealingFactor keeps them alive, but it's still ''not pretty''.
138* HeroicSelfDeprecation: Both halves have some degree of this. {{Downplayed}} with Vivienne, who is scared of losing control of her new power and becoming something like Ghidorah, to the point that she needs to hear a couple YouAreBetterThanYouThinkYouAre speeches. ZigZagged with San, who normally has decent levels of confidence when it comes to anything other than being a good brother, but will [[ItsAllMyFault mentally skin himself alive]] if he realizes he's caused Vivienne any significant psychological pain.
139* HeroOnHiatus: During their second {{Metamorphosis}}, whilst Viv and San are pupating, the story's main focus switches to Monarch and the Russells.
140* HitAndRunTactics: They use a bit of this when engaging and mutilating [=MaNi=]/Elder Brother in Chapter 17.
141* HoldingBackThePhlebotinum: In the Timeline, Monster X [[spoiler:being in the [[HollowWorld Realm Below]] renders them unavailable when the Titans on the surface begin behaving violently, and thus Monster X can't talk the Titans into calming down nor can the Titans communicate to Monster X what's provoking them so Monster X can then pass that information on to the humans]].
142* HoldingHands: In Chapter 13, Monster X begins tracing their fingertips along the underside of Thor's hand, but Thor grips the tips of their fingers [[spoiler:because he's emotional over his son's death long ago and the role that Ghidorah played in it]]. In the final chapter, [[spoiler:Susan]] grasps Monster X's finger with both her hands after she's made peace with them. In the non-canon ''Fanfic/AbraxasEmptyFullness'' HalloweenEpisode "[[https://archiveofourown.org/works/46831738/chapters/127672459 Come Little Monster, I'll Take Thee Away]]", Ling holds Monster X's hand for some time when old feelings between her and Vivienne are stirring up and they're conversing intimately. See Vivienne's folder for more examples.
143* HorrifyingHero: A part-[[OmnicidalManiac Ghidorah]] monster who is half a [[InhumanHuman forcibly-revived dead woman]], and half [[DraconicAbomination one of Ghidorah's heads themselves]]. Their [[BodyHorror first form]] is especially horrifying; [[spoiler:and even their final form doesn't look like the kind of monster you'd normally associate with the good guys, nor does it look like anything you'd want to be within ten miles of if you didn't know its character]]. With all this in mind, it's understandable why so many people who don't know the full truth about Monster X are so wary of them and even the ones who ''do'' know can still be a little uncomfortable. Regardless, Monster X is genuinely on the side of good, and they (mainly Vivienne) are even more concerned about averting needless collateral than the [[DestructiveSaviour average Protector Titan]] is.
144* HorrorDoesntSettleForSimpleTuesday: PlayedWith. Their first, more horror-laden rebirth occurs on or very shortly after the New Year.
145* HowlOfSorrow: A ZigZagged case occurs in Chapter 17, [[spoiler:when they let loose a noise that's simultaneously cackling and sobbing, the latter due to mourning the deaths of Thor and [[RedemptionEqualsDeath San-2/Youngest Brother]]]]. See Vivienne's folder for another example.
146* HugeGuyTinyGirl: PlayedWith; and a non-romantic but very [[PlatonicLifePartners life-partner]] example. San and Vivienne before their fusion were a human woman of short stature and one of the heads of the largest Titan on record, respectively.
147* HybridsAreACrapshoot: Ultimately {{subverted}}. Their first hybridized form is defective and plagued by crippling BodyHorror, but with some external aid, all of this gets fixed up during their second {{Metamorphosis}}.
148[[/folder]]
149
150[[folder:Tropes I-P]]
151* IconicAttributeAdoptionMoment: [[spoiler:Their first two forms are quite unique and are a case of YouDontLookLikeYou comparative to the original Toho version. Once they reach their final form, they're more like the original incarnation of Monster X]].
152* IDidntMeanToTurnYouOn: [[spoiler:They have no idea that Rodan's chest, which they frequently slap or prod in confrontations with him, is an erogenous zone]]. In "Ain't That a Kick in the Head", they're quite mortified to realize they were inflicting this trope [[spoiler:on Rodan to the point where their behavior towards him was MistakenForFlirting]].
153* TheImmune: It's indicated in the fic, and explicitly confirmed by [[https://hrodvitnon.tumblr.com/post/689311522082668544/ Word of God]], that the Many can't infect Monster X since Monster X is already a part-Ghidorah lifeform in their own right.
154* ImpaledWithExtremePrejudice: Suffers this while battling in Chapter 13.
155* ImprobableAimingSkills: In their final form, [[spoiler:they fire a Destroyed Thunder beam at [=MaNi=]/Elder Brother from across a considerable distance by Titan proportions and they squarely hit their mark]]. Especially notable when you consider that this is the first time they're using such an ability, although it's likely partly justified by San's memories of how to aim a Gravity Beam, which displays similar properties.
156* ImprovisedWeapon: Both San and Vivienne utilize this trope a couple times, using it against [=MaNi=]/Elder Brother in both instances. The first time, Monster X uses a pair of stalactites as slashing weapons; the second time, they use a broken-off church steeple to impale [=MaNi=] to the ground.
157* InASingleBound: It's capable of propelling its body through the air via electrical pulses.
158* InnocentInnuendo: An InUniverse one. They [[spoiler:punch Rodan in the chest]], oblivious to the fact [[https://hrodvitnon.tumblr.com/post/662855620668653568/ this is basically equivalent to kissing in Rodan's species]].
159* InSeriesNickname: Is designated Subject G by Jonah’s paramilitary. San's head is distinguished from Vivienne as Subject G-1a once they become aware the creature is TwoBeingsOneBody.
160* TheInsomniac: In "[[https://archiveofourown.org/works/46831738/chapters/117962629 Sermones ad Mortuos]]", Monster X apparently struggles to sleep for several days [[spoiler:when they're grieving]]. See Vivienne's folder for another example.
161* InstantExpert: San picks up the English vocabulary directly from Vivienne's brain. According to the author, Vivienne in turn is able to use her Bone Singer ability fluidly despite her lack of experience when human due to "piggybacking" on San's [[https://hrodvitnon.tumblr.com/post/631249528601935872/ natural understanding of Titans' communication]].
162* InstantHumiliationJustAddYouTube: In "Ain't That a Kick in the Head", they're mortified when Ling informs them that the MistakenForFlirting incident [[spoiler:with Rodan performing a full-blown courtship dance for Monster X]] was videod by Titan observers and has near-instantaneously blown up on [=YouTube=].
163* InterspeciesRomance: Both Viv and San have BelligerentSexualTension with Rodan, [[spoiler:and the Timeline indicates they become mates in the future]].
164* IntroducedSpeciesCalamity: {{Discussed|Trope}}. [[spoiler:Ichi]] notes in Chapter 17 that by the time the BigBad is done with Monster X, they should become just as much of an ecosystem-disrupting invasive species to Earth's biosphere as Ghidorah already was.
165* ItsPersonal:
166** Besides despising Alan Jonah based on matters of principles, both Viv and San have a very personal hatred of the old EcoTerrorist for caging and torturing them, not least because in San's case it brings back very traumatic memories according to [[https://hrodvitnon.tumblr.com/post/673233908668694529/ Word of God]].
167** Monster X overall has a very personal stake in [[spoiler:the fight against Keizer Ghidorah]]. It has caused both San and Vivienne ''so'' much pain; from taking Vivienne's human life away from her to [[spoiler:tormenting both Viv and San with repeated MindRape]].
168** Monster X has a ''very'' personal desire to kill [=MaNi=]/Elder Brother after he viciously torments Viv and San both, and after he [[spoiler:goes after Manda]].
169* ItsRainingMen: Rodan drops them off next to Yonaguni this way in [[https://www.fanfiction.net/s/13357907/13/ Chapter 13]].
170* 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.
171* JawDrop: Their jaw falls in shock in "[[https://archiveofourown.org/works/46831738/chapters/120253627#workskin Ain't That a Kick in the Head]]" when they ''finally'' twig what Rodan is doing: [[spoiler:giving them a courtship display]].
172* TheJuggernaut: It takes a ''lot'' of punishment to even slow Monster X down when it really gets going.
173* {{Kaiju}}: Monster X is officially classified as a Titan. In their first form, they're roughly the size of a Skullcrawler, and after their second transformation, they're almost the same size that Kong was in ''Film/KongSkullIsland'', as [[https://hrodvitnon.tumblr.com/post/620940544685834240/ this official artwork by the author demonstrates]].
174* LightFlickerTeleportation: They pull a Lightning-Flash Flicker Teleportation on [=MaNi=]/Elder Brother during the FinalBattle.
175* LightLiegeDarkDefender: Somewhat. At first, San and Vivienne have this kind of dynamic, although since becoming a SiblingTeam they're roughly equal in terms of BewareTheNiceOnes.
176* LightningBruiser: It's large, fast and extremely tough.
177* LightningReveal: [=MaNi=]/Elder Brother spots them via a lightning-flash amid the darkness in Berezniki in Chapter 17.
178* LogicalWeakness: It's speculated in Chapter 16 and [[https://hrodvitnon.tumblr.com/post/656464198292881408/ confirmed by the author]] that because of how differently Monster X's HealingFactor works compared to Ghidorah's, [[spoiler:it can't regrow a duplicate if San or Vivienne's head is decapitated from it]].
179* LongLived: [[spoiler:Ghidorah's middle head]] implies in Chapter 14 that Monster X is this at the very least, and it's probably even TheAgeless like Ghidorah.
180* MacGuffinSuperPerson: They've become this after [[spoiler:Ghidorah's minds have regenerated]], with [[spoiler:Ghidorah actively wanting the hybridized Vivienne back for [[BabyFactor particularly vile]] [[TheAssimilator purposes]]]].
181* MartialPacifist: They're very much this, trying to avoid unnecessary fighting but proving incredibly fearsome when pushed the wrong way.
182* MatingDance: [[spoiler:Their FriendlyRivalry spar with Rodan ends up being an avian-like dance, with Monster X doing some things that are quite ''suggestive'']].
183* MeaningfulLook: They make it clear with but a glare at Rodan that they know he brought Manda to a Titan warzone and are unhappy about it, even if he had a point that Manda was more unsafe being left unsupervised at his original location; in Chapter 17.
184* MeaningfulName: It was named Monster X in reference to Ghidorah's Monster Zero designation, due to the two-headed Titan's resemblance. Its ProtagonistTitle name in Chapter 10 is based on the [[UsefulNotes/{{Gnosticism}} Gnostic figure]]. See Vivienne and San's respective folders for more examples.
185* MentalFusion: [[spoiler:Viv and San experience this once they metamorphose into their single-headed final form. As a result, their default mental state is a merger of both their personalities which refers to themself as a singular being; although Viv and San's personalities retain their individuality, and they can split out of this merged personality back into the original two in order to speak separately]].
186* MergingMistake: When San fuses himself to Vivienne, their first hybridized form ends up plagued by crippling, painful BodyHorror in addition to {{inverted}} {{power incontinence}}. According to [[https://archiveofourown.org/comments/247897682 Word]] [[https://hrodvitnon.tumblr.com/post/692341609101148160 of God]], this is due to a combination of San not knowing that the hybridization needed a longer gestation period and not knowing enough about human biology.
187* {{Metamorphosis}}:
188** Monster X is formed inside San's decapitated head by him reviving, regenerating and transforming Vivienne's body via feeding his own enzymes into her system, before eventually being (re)born from the head, and it's not all that dissimilar to a real-life metamorphosis.
189** A second, shorter metamorphosis is instigated externally by Mothra in [[https://www.fanfiction.net/s/13357907/7 Chapter 7]]. This one technically counts as something of an EmergencyTransformation, fixing Monster X's PowerIncontinence and BodyHorror.
190** The third and final metamorphosis [[spoiler:is instigated by Ghidorah as an EmergencyTransformation to keep Vivienne alive]].
191* MetamorphosisMonster: It goes through three different forms in total over the course of the story.
192* MirrorCharacter: Apart from Viv and San's individual examples (see below for details); they're arguably this to Godzilla. Godzilla, 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; is arguably a reflection of what [[LongLived Monster X]] will likely look like after thousands or even millions of years.
193* MistakenForFlirting: Hilariously enough. They [[IDidntMeanToTurnYouOn have no idea that they're poking an egregious zone]] every time that they prod or put a hand on Rodan's chest during confrontations, [[spoiler:which causes Rodan to believe they wish to mate with him and leads him to prepare accordingly in "Ain't That a Kick in the Head"]].
194* MixAndMatchCritters: {{Justified|Trope}} by its hybrid origin. Monster X's first form resembles a reptilian MonstrousHumanoid, and their second form is noted in [[https://www.fanfiction.net/s/13357907/10 Chapter 10]] to possess a mix of reptilian and mammalian anatomy, whilst their final form is an upright-standing DraconicHumanoid [[spoiler:with wings]].
195* MonstrousHumanoid: Its first form is recognizably humanoid if hunched over and quadrupedal; in its second form, San and Vivienne lose most physical remnants of Vivienne's humanity and look much more bestial; and their final form is [[spoiler:a DraconicHumanoid]]. For San, these humanoid-bodied states qualify as temporarily being a HumanoidAbomination.
196* MonstrousMandibles: In their final form, [[spoiler:they have the Functional type, in the form of two jawbone-like pieces on either side of their actual jaw which can apparently flex. [[https://hrodvitnon.tumblr.com/post/697040294509690881/ Word of God]] suggests that these mandibles probably function as additional biting tools]].
197* MoreTeethThanTheOsmondFamily: According to [[https://hrodvitnon.tumblr.com/post/697040294509690881/ Word of God]], in Viv and San's final form, they have two distinct sets of teeth [[spoiler:in their head,]] just like Vivienne's head in their second form possessed.
198* MorphicResonance: Besides the EyesAreMental...
199** San's head retains the same structure as Ghidorah's three heads, and Monster X retains a Ghidorah-like digitigrade leg shape. It's also worth noting, [[spoiler:in their single-headed final form, the left eye is San's color, just as San was originally the left head of Ghidorah]].
200** Vivienne loses her human form's facial structure after the second {{Metamorphosis}}, but there are few recognizable physical traits (such as Monster X's hands retaining the distinct shape of Vivienne's hands when she was human) that can still identify her individually.
201* MovingBeyondBereavement: The first chapter of ''Abraxas: Empty Fullness'' is about them gradually (and with needed intervention) coming to terms with the recent death of a dear loved one. See Vivienne's folder for another example.
202* MultipleHeadCase: Of the TwoBeingsOneBody type. 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.
203* NearDeathExperience: They seem to have one before Mothra revives them during their encounter in Chapter 7, similar to Madison's in the movie. See San's folder for another example.
204* NeckLift: They hold a Many MindHive above the ocean by its neck using their PrehensileTail, in Chapter 13.
205* NeutralNoLonger: When [[spoiler:the regenerating Ghidorah]] becomes an active threat, San and Vivienne are part of the Titans' fight against it.
206* NondescriptNastyNutritious: PlayedWith. According to [[https://hrodvitnon.tumblr.com/post/686616424688599040/ Word of God]], manmade radiation leaves a metallic taste in Monster X's mouth if they consume it.
207* TheNoseKnows: Monster X has a heightened sense of smell that enables them to identify things that wouldn't be immediately obvious, such as smelling and identifying blood, smelling another creature's terror up close, and smelling high levels of radiation in the air. See San's folder for another example.
208* NoSell: San and Vivienne can take a lot of punishment, particularly when enraged to action.
209* NotAMask: {{Downplayed}} in their final form. [[spoiler:Methuselah asks why Monster X wears a skull-like helm over their head, unaware it's actually exoskeletal armor on their head]].
210* OddFriendship: Viv and San's sibling bond is seen as this by Monarch once they become aware of Monster X's true nature.
211* OhCrap: When Viv and San's arm is [[spoiler:severed and they don't grow a new one after several seconds]], San observes it aloud, and their heads share a look followed by the narrative saying:
212-->Oh, balls.
213* OneManArmy: It proves to be this when agitated. Even when it's first reborn, in Vivienne's agitated state it kills multiple mercenaries and [[NoSell No-Sells]] their ammunition before they manage to get it behind a containment field. After the second {{Metamorphosis}}, if Vivienne and San are pissed off, they can go toe-to-toe with mature and more experienced Titans.
214* OurDragonsAreDifferent: A two-headed hybrid Titan (human and Ghidorah) with leathery skin and bony protrusions, created by San transforming and essentially merging with Vivienne -- as a result of the latter characteristic, the two heads' minds essentially have AGirlAndHerX esque dynamic. In their second form, they have no wings and are mainly quadrupedal like eastern dragons -- in their final form, [[spoiler:they're a DraconicHumanoid with [[RetractableAppendages retractable wings]] that enable flight]]. Viv and San have Ghidorah's bio-electricity, but they have a somewhat different set of powers and the lightning they generate is red-tinted. They're also essentially the "offspring" of a SatanicArchetype DraconicAbomination, but they're highly benevolent and highly fierce.
215* OurHeroIsDead: Chapter 6 ends with both San and Vivienne rapidly losing consciousness after they've suffered a HeroicRROD that left several of their insides on their outside, after San expressed worry that they might die. Chapter 7 reveals that they've more or less fallen into a coma.
216* OOCIsSeriousBusiness: When Monster X is mourning [[spoiler:Susan's death, not only do]] they become despondent and disinterested in sparring, [[spoiler:but their [[TwoBeingsOneBody two halves]] in their final form become de-synchronized and disjointed. Rodan rightly guesses that Monster X is in need of an intervention from another Titan]]. See Vivienne's folder for another example.
217* PassiveAggressiveKombat: According to [[https://hrodvitnon.tumblr.com/post/747931705213583360/ Word of God]], [[spoiler:after Monster X helped to ruin Camazotz's conquest of Skull Island, Camazotz and Monster X are willing to interact civilly when neutralizing Many instances, but it's always full of barbs and snarks]].
218* PayEvilUntoEvil: Viv and San tend toward this: Vivienne does it when she's pushed too far, and with San this trope is the main way his sadistic side manifests.
219* {{Permafusion}}: Monster X is the result of Ghidorah's severed left head, called San here, being mixed with Dr. Vivienne Graham. The hybrid originally comes about when San's original head, keeping a revived and mutilated Vivienne alive; feeds the head's own Draconic Abomination enzymes into Vivienne's system (which regenerates and mutates her body to form a human-Ghidorah Artificial Hybrid), and the head then transfers San's mind into a second head growing from the gestating hybrid's back. [[spoiler:After the fusion, the only way to sever San and Vivienne from each-other is if one of their heads is severed from their shared body, leaving the other one a single-headed hybrid without its other head, on account of Monster X's Healing Factor not working the same way that Ghidorah's did; but even this weakness is practically removed during Monster X's metamorphosis into their final hybrid form. ]]
220* PercussiveMaintenance: They cause this in Chapter 6 by feeding enough of their powers' electrical energy into the [[spoiler:Ural]] outpost.
221* PhlebotinumOverdose: Absorbing too much of [[spoiler:[=MaNi=]/Elder Brother]]'s electrical energy causes [[spoiler:the massive muscle overstimulation to tear Viv and San's body apart, nearly killing them]].
222* PhlebotinumRebel: It's implied Ichi/Eldest Brother wanted the result of Vivienne's Metamorphosis to be subservient to him before San's decapitation, and fortunately San has the [[MinionWithAnFInEvil personality traits]] that lay the groundwork for his HeelFaceTurn.
223* PintSizedPowerhouse: They're comparatively small by most Titans' standards, but ''[[HorrifyingTheHorror Rodan]]'' is mesmerized by what they're capable of during an UnstoppableRage.
224* PlatonicDeclarationOfLove: In their final form which can't vocalize human tongues anymore, Monster X vocalizes "a low murmur that sounds vaguely like 'I love you too'" [[spoiler:to Susan before the latter passes, as revealed in "Sermones ad Mortuos"]].
225* PlatonicLifePartners: Specifically Sibling Life-Partners.
226* PostVictoryCollapse: Downplayed. After [[spoiler:the partly-resurrected Ghidorah's body is destroyed and Monster X personally kills the last head]], they collapse on their back amidst a laughing/crying fit. They quickly pick themselves up to find [[spoiler:Manda]].
227* PowerDegeneration: It's implied Monster X would've suffered this had the duo's {{Healing Factor}}'s serious design flaw not been fixed, as [[LampshadeHanging lampshaded]] by Mariko in Chapter 14.
228* PowerEchoes: Besides San's case (see his folder for details), in [[spoiler:their final form]] their dual voices are described as echoic.
229* PowerGlows: When its powers are being used, or when they flare due to Vivienne experiencing sudden or strong emotions, producing a crimson/orange glow.
230* PowerIncontinence: {{Inverted}}. In their first form, Monster X has too few traces of metal in its body to conduct electricity like Ghidorah did, and they struggle to awaken their electrical powers. They succeed by using emotions such as hatred or anger.
231* ThePowerOfHate: This helps wakes up their PsychoactivePowers in Chapter 6.
232* PrehensileTail: Their tail can be used for strangling in a fight.
233* PrimalChestPound: They (mainly Vivienne) incorporate apelike chest-pounding as part of their new signature intimidation display.
234* PsychoactivePowers: Its powers are fuelled by negative emotions such as hate or (a more easily-controllable one) anger, just as Ghidorah's powers were.
235* PullingThemselvesTogether: {{Downplayed}} when they [[spoiler:reattach a severed arm]]. They also do this after [[spoiler:their body is torn apart and they enter their next {{Metamorphosis}}]].
236* PupatingPeril: During all three Metamorphoses, Monster X draws this kind of awe and anxiety from humans waiting to see what will emerge. In the cases of Monster X's second and final metamorphoses, there's worry among the humans before the hybrid emerges that it'll be corrupted and as bad as Ghidorah.
237[[/folder]]
238
239[[folder:Tropes Q-Y]]
240* QuizzicalTilt: They do this rather nightmarishly whilst in the process of [[spoiler:ripping apart [=MaNi=]/Elder Brother]], in Chapter 17.
241* RapidFireNo: Both Viv and San are respectively inclined towards making these when they're distressed about something.
242* RedBaron: By the time of the final chapter, humans have quickly given them several names. [[https://hrodvitnon.tumblr.com/post/668150068002553856/ Word of God]] also says that Monster X has a Titan classification unique to them as an "Executioner" Titan.
243* RedGreenContrast: Either half of Monster X retains their distinct eye color (Vivienne: hazel-green and San: red). Rather than representing a ''moral'' conflict per se (although there are symbolic elements of that due to [[HeelFaceTurn San's past]] contrasted with [[NiceGuy Vivienne]]'s); the contrast represents the duo's complimentary SiblingYinYang relationship. The red-eyed San was originally 1/3 of an [[SatanicArchetype evil]], hate-fueled PersonOfMassDestruction before fusing to Vivienne, while the green-eyed Vivienne was a lifelong NatureLover and a supportive NiceGirl.
244* RedIsHeroic: It produces autumn-colored lightning.
245* RedIsViolent: Ultimately ZigZagged. Their powers which produce red light or lightning are usually triggered by emotions such as anger and hate, but great enough joy or happiness can also get a bioluminescent red pulse out of them.
246* ReligiousAndMythologicalThemeNaming: It's eventually named after the dualistic deity Abraxas from Gnosticism, fitting what Monster X itself is as a fusion of opposing concepts (human and Titan, NiceGirl and (redeemed) {{Sadist}}, male and female, etc.).
247* ReluctantPsycho: Viv and San's part-Ghidorah biology influences their capacity for psychotic brutality when one or both of them is sufficiently enraged or panicked, but it fortunately only takes over their actions if they're pushed too far -- [[https://hrodvitnon.tumblr.com/post/653745095218266112 according to the author]], in Viv and San's case it's like an aftertaste of what Ghidorah experiences. More than this, Viv and San have issues dealing with Vivienne's untreated PTSD and both are saddened by it.
248* RemovedAchillesHeel: Monster X's metamorphosis into their final form enables them to stimulate their muscles via ShockAndAwe to produce bursts of speed and movement, without the risk of it tearing their body apart. See San's folder for another example.
249* RetractableAppendages: {{Downplayed}} in their final form. [[spoiler:They have giant wings which fold and reshape into an [[https://en.wikipedia.org/wiki/Elytron elytron]]-like bone casing when not in use]]. According to [[https://hrodvitnon.tumblr.com/post/689311522082668544/ Word of God]], Monster X's ability to do this works the same way as the Many's ability to reshape their biomass.
250* RoarBeforeBeating:
251** They attempt pulling this during a training scuffle with Godzilla based on wolverines' fighting style in Chapter 9.
252** Come Chapter 17, and they basically have a war chant for the other Titans before fighting [[spoiler:Keizer Ghidorah]]:
253--->"''RIP AND TEAR!''"
254** See Vivienne's folder for another example.
255* SayMyName: One of them (it's actually hard to tell which head) screams Jonah's name in rage when they rampage in Chapter 6.
256* SerpentOfImmortality: Downplayed, but it has a serpentine quality to it, and it's indicated in Chapter 14 that it'll live at least for thousands of years, possibly even forever if not killed.
257* SharedDream: Thanks to their [[TwoBeingsOneBody shared neurology]], Viv and San can share and enter one-another's dreams, as San does during the first NightmareSequence – he has less success during the second sequence, though not for lack of trying.
258* ShockAndAwe: Has inherited Ghidorah's bio-electricity, referred to by San as "the storm", although Monster X's abilities aren't quite the same as Ghidorah's. Although their WeatherManipulation is less intense, Monster X can give off blasts of electrical energy through their body and legs which enable them to commit feats of massive speed and jumping by stimulating their muscles. [[https://hrodvitnon.tumblr.com/post/672405103227060224/ Word of God]] also reveals they can utilize the Earth's electric field to fly in ways that not even Rodan and Mothra can.
259* ShutUpHannibal:
260** They give Jonah a HannibalLecture in response to one of his efforts to break Vivienne down in Chapter 6.
261** Both San and Vivienne repeatedly tell [[spoiler:Ghidorah's voices]] to shut up -- [[spoiler:the voices]] either keep pestering them or will come back for more later. They ultimately deliver this to [[spoiler:Ichi/Eldest Brother]] face-to-face in Chapter 17:
262---> '''[[spoiler:Ichi: THIS IS BUT THE ADDITION OF TIME TO AN OLD SENTENCING. WE WILL BE BACK. WE WILL ALWAYS COME BACK, ONE WAY OR ANOTHER]].'''\
263'''Monster X:''' Not if we find all the pieces first. But even if we don't, we'll still be there to kick your ass all over again.
264* SiblingFusion: Due to Ghidorah's heads being brothers, Vivienne and San are considered brother and sister after merging into a [[MultipleHeadCase two-headed]] ArtificialHybrid. [[spoiler:They experience [[MentalFusion further fusion]] in their final form]].
265* SiblingMurder: In their final form, Viv and San [[spoiler:deliver {{Karmic Death}}s to [=MaNi=]/Elder Brother (although [[https://hrodvitnon.tumblr.com/post/690163715553820672/ Word of God]] has hinted they might have merely rendered him comatose rather than killed him outright) and Ichi/Eldest Brother. Whilst San in particular is both entities' actual brother, Vivienne is also considered by them to technically be their sister]].
266* SiblingTeam: Vivienne and San are considered brother and sister after their merger (analogous to Ghidorah’s heads being brothers), and they eventually become this kind of team; learning to work together and becoming each-other’s emotional crutches.
267* SiblingYinYang: Characters note InUniverse how San and Vivienne are polar opposites in many regards yet are an [[VisualPun inseparable]] SiblingTeam. It influences their scientific MeaningfulName.
268* SickeningCrunch:
269** Their first form, crippled by the BodyHorror, at times produces muffled popping sounds when it moves with effort.
270** There's also a few of these sounds during their fight against [=MaNi=]/Elder Brother in their second form, and it's ambiguous at times which Titan is being injured.
271** See San's folder for another example.
272* SignatureRoar: The author has [[https://archiveofourown.org/works/20059573/chapters/54974494?view_adult=true mentioned]] Monster X has the same vocalizations as the original Toho incarnation (at least Vivienne's head does, as San's head is implied to have the same roar as Ghidorah).
273* SilenceOfSadness: In "Sermones ad Mortuos", Monster X barely says anything at all when they're mourning [[spoiler:the death of Susan]]. See the below folders for individual examples.
274* SilverBullet: PlayedWith. A strictly metaphorical case, but Monster X's bone armor becoming silver-infused (a notable contrast to Ghidorah's gold-infused scales) fits with RealLife lore describing silver as a repellent against evil supernatural forces, as noted in [[https://www.fanfiction.net/s/13357907/10/ Chapter 10]].
275* SkeletonsInTheCoatCloset: PlayedWith. From their second form onwards, Monster X's protruding bone armor looks vaguely like pieces of actual armor made of bone being worn atop their dark flesh.
276* SkullForAHead: In Viv and San’s first form, Vivienne’s face still looks vaguely human but with an extremely skeletal, gaunt-looking structure. [[spoiler:In their final form as Monster X, their new singular head looks very much like it’s wearing a large draconic skull as a helm, [[NotAMask which is actually an exoskeletal part of their flesh and bone]]]].
277* SlasherSmile: Besides Vivienne's individual example under her folder, Viv and San give [=MaNi=]/Elder Brother and then [[spoiler:Ghidorah]] a couple such grins when fighting against either of them in Chapter 17. They also give Rodan a couple such looks [[spoiler:in their final form, once because they're pissed at him bringing Manda to a war zone (albeit on reasonable grounds) in Chapter 17; then again before dueling him in Chapter 18]].
278* SleepDeprivation: On top of Vivienne's [[TheInsomniac insomnia]] and San's individual sleep deprivation in their first hybrid form (see the below folders for the respective details); in their second form, Viv and San still have on-and-off sleeping issues due to Vivienne's PTSD [[spoiler:and Ghidorah's episodic MindRape]].
279* SnarkToSnarkCombat: They engage in some of this with Rodan in Chapter 18.
280-->'''Rodan:''' Only half of you can say that. The other can just bluster and marvel at my skill while I leave you in the dust.\
281'''Monster X:''' Try it, spring chicken. I'm going to show you how to ''really'' fly.
282* SpeakIllOfTheDead: Vivienne speaks ill of San's abusive brothers who are currently dead after the battle at Boston, in Chapter 5. San, who has no real love for them, eventually echoes this.
283* SpeechImpediment: According to the author, Viv and San's physical speaking voices in their [[BodyHorror primitive first hybridized form]] sound like [[https://www.youtube.com/watch?v=8-vdHpvoUJE&t=155s the Gravemind]] from ''VideoGame/Halo2'', with a slight underlying hint of a masculine or feminine voice depending on which of the two entities is speaking. Although Vivienne's dialogue in scenes written from her P.O.V. is formatted fluidly, scenes told in transcript form heavily imply that she's actually speaking in a slow, halting manner with gasps and breaks like the Gravemind's speech. See San's folder for another example.
284* SplitPersonality: [[spoiler:{{Discussed}} by Viv, San and Susan in the final chapter. Susan asks if they're essentially this trope after Viv and San's TwoBeingsOneBody has escalated into MentalFusion territory. Vivienne has difficulty explaining, but she says they're simultaneously and paradoxically two separate beings and a singular composite being]].
285* StealthHiBye: Slightly downplayed in "Ain't That a Kick in the Head". The second time that Monster X approaches Rodan, the latter, who is perching on Mount Fuji[[note]]Not to be confused with Mount '''Fiji''' from the ''King of the Monsters'' closing credits[[/note]], is taken by surprise when Monster X suddenly descends from the sky within spitting distance; having apparently not sensed Monster X coming like he did the first time (possibly due to being distracted).
286* StopWorshippingMe: Downplayed. The author has [[https://hrodvitnon.tumblr.com/post/691330762759421952/ passingly]] indicated that [[GiantAnimalWorship Titanic]] {{cult}}s worshipping Monster X exist, and that Monster X doesn't exactly have a high opinion of their reverence.
287* StrongerWithAge: The author has confirmed Monster X will gradually grow [[https://hrodvitnon.tumblr.com/post/683750727473053696/ bigger]] and [[https://hrodvitnon.tumblr.com/post/658643317372977152/ stronger]] with age. She also [[https://hrodvitnon.tumblr.com/post/656541539637608448/ said]] this would've happened to their second form if they'd never metamorphosed into their final form.
288* StunnedSilence: Viv and San have a very brief one when Thor mentions his son's death in Chapter 13.
289* SuperPrototype: Besides being a FlawedPrototype to the Many (see above), Monster X can also be considered this trope to them. Viv and San are far more, shall we say, ''sane'' than the Many are, as well as being much more mentally and physically consistent and more capable of thinking for themselves even when Monster X was in their defective first form. ZigZagged in their first form which had many crippling defects, but from their second form onwards, Monster X is powerful enough to win a fight against a Many MindHive. [[spoiler:Even Ghidorah seems to somewhat consider Monster X to be this trope, as it upgrades Monster X's body into a more powerful form to preserve the Vivienne half and prepare her for assimilation; instead of handing her over to the Many, which Ghidorah regards as little to nothing more than tools]].
290* SuperReflexes: Physically, it can move its body with SuperSpeed in its final form, and it's no slouch in terms of reacting in time.
291* SuperSenses: Alongside San's [[BizarreAlienSenses Bizarre Alien Sense]], the conventional five senses he has are extremely heightened compared to humans'.
292* SuperSpeed: Once they reach their final form, they become capable of safely doing this with their ShockAndAwe powers. It works the same way a lightning strike causes involuntary muscle contractions that can throw a person backwards, but much more powerful.
293* SuperToughness: Conventional weaponry which would ''obliterate'' an armoured human barely slows them down and takes time to seriously maim them – and that was when the duo was still in their FlawedPrototype first form.
294* SurvivalMantra: Reciting the Elder Futhark has become a psychological one which helps gives Vivienne some mental defense or shelter from impending psychological trauma. Her MadnessMantra (see her folder) is also a very extreme and fragile Survival Mantra.
295* SwallowedWhole: Besides how Ghidorah originally ate Vivienne, and the example under San's folder; [[spoiler:in Chapter 16, the partly-regenerated Ghidorah takes Monster X into its BellyMouth to instigate their next {{Metamorphosis}}]].
296* TailSlap: Their tail can be used offensively as a deadly whip this way.
297* TalkingInYourDreams: Due to their TwinTelepathy, San and Vivienne can share dreams when they sleep.
298* TalkingToThemself: In its first form, Viv and San physically talking with each-other in FlipPersonality is initially mistaken by Jonah's paramilitary as a sign of insanity in Chapter 2.
299* {{Technopath}}: PlayedWith. [[https://hrodvitnon.tumblr.com/post/652105848427020288/ The author]] has indicated that Monster X can probably listen in to radio transmissions.
300* TeethClenchedTeamwork: With Mariko in Chapter 6, whom neither San nor Vivienne wholly trusts.
301* TerribleTicking: Not unlike Ghidorah ([[https://hrodvitnon.tumblr.com/post/653745095218266112/ but to a milder extent]]), they hear an echo of the Old Noise when they hear an ORCA signal, with [[https://hrodvitnon.tumblr.com/post/666120662644080640/ Word of God]] describing it as a noise that causes the mind to scream attempting to block it out.
302* ToServeMan: {{Downplayed}}. Word of God [[https://hrodvitnon.tumblr.com/post/686436160836337664/ here]] describes two things which would surely piss Monster X off to the point of overriding any reluctance Vivienne might have about eating members of her former species entirely. However, Word of God also agrees [[https://hrodvitnon.tumblr.com/post/686453920098353152/ here]] and [[https://hrodvitnon.tumblr.com/post/686455399591903232/ here]] that Vivienne wouldn't exactly be tempted to eat long pig a second time afterwards.
303* TranquilFury: Monster X is frighteningly quiet and calm while it brutally takes much-deserved retribution upon [[spoiler:[=MaNi=]/Elder Brother]].
304* TransformationHorror: Viv and San's first transformation specifically involves Horrifying Metamorphosis, with Vivienne experiencing a couple violent "spurts".
305* TrashTalk: Viv and San use this against Jonah while fighting [[spoiler:the Many MindHive he's linked to]] in Chapter 13. They also taunt Rodan that he can do better whilst he's [[spoiler:fighting them]] in Chapter 18.
306* TraumaticSuperpowerAwakening: A variation, and slightly downplayed. In their [[PowerIncontinence crippled]] first form, the hybrid's Ghidorah-inherited storm powers fully awaken when Vivienne explodes with rage over finding out about the nature behind the {{disposable vagrant}}s' disappearances, in Chapter 6.
307* {{Troll}}: They get to return the favour in kind towards Rodan later in the story, avenging his own earlier prodding of their buttons.
308* TroubledFetalPosition: They, mainly Vivienne when she's controlling their body, go into this position a couple times when Vivienne's confused or has just had a PTSD episode.
309* TwinTelepathy: San and Vivienne are able to communicate with each-other this way in addition to vocal communication, due to their shared nervous system below the necks. It also causes them to share impressions of each-other's emotions. They're even able to let the other view and experience their memories.
310* TwoBeingsOneBody: Monster X was formed by San transforming Vivienne into a part-Ghidorah hybrid while transferring his consciousness to be the mind of her body's new second head.
311* TwoFaced: Besides the example listed under San's folder, both their heads suffer this [[spoiler:due to their second HeroicRROD in Chapter 16]].
312* UndyingLoyalty: Viv and San have started exhibiting this towards each-other.
313* VaderBreath: Their breathing is reduced by dehydration to wheezing by the time Mariko is first introduced to them.
314* VampiricDraining: San's head apparently retains this ability from when he was part of Ghidorah, and he attempts to use it defensively against [[spoiler:[=MaNi=]/Elder Brother]] in Chapter 16. Monster X in its [[spoiler:single-headed final form]] uses this ability to suck [[spoiler:[=MaNi=]/Elder Brother's body]] dry of energy, which [[https://hrodvitnon.tumblr.com/post/689311522082668544/ Word of God]] notes essentially mummifies and de-animates the Many-derived biomass if not kill it outright.
315* VictoriousRoar: {{Subverted}} in Chapter 17. After Viv and San have finally seen the monster that's caused them so much suffering killed, all they can bring themselves to do is simultaneously giggle in triumph and bemoan the deaths the battle entailed equally.
316* VisualPun: They're physically inseparable in that they're literally TwoBeingsOneBody, which fits with the close emotional bond they develop.
317* VoicesAreMental: ZigZagged. 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}}'', and only when they scream do their voice/s prominently sound like a mix of Ghidorah's roar and a human scream. 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.
318* VolcanicVeins: This is one of the main ways their PowerGlows manifests.
319* WalkingTechbane: ZigZagged. They can cause appropriately Titan-level power fluctuations around technology, but they also at one point instead cause PercussiveMaintenance.
320* WallCrawl: They attempt this in an underground pit, using their claws like climbing axes, in Chapter 16.
321* WeAllDieSomeday: They say as much to Manda, and they admit they expect to die themselves one day, but they also say they intend to fight and be strong to ensure that day comes later rather than sooner.
322* WeatherManipulation: Somewhat downplayed, but their electrical powers can manipulate pre-existing stormy weather, making it intensify or breaking it at will. [[https://hrodvitnon.tumblr.com/post/672405103227060224/ Word of God]] says that Monster X in their final form can generate their own storms like Ghidorah can, but they aren't as powerful.
323* WhoWantsToLiveForever: They're not immune to existential angst over knowing they'll long outlive every human around them including the ones Vivienne loves dearly. [[spoiler:Ichi/Eldest Brother tries to get under Vivienne's skin by pointing this out, and Monster X (particularly San) starts feeling it in "Sermones ad Mortuos" after his first human loved one besides Vivienne dies of old age]].
324* TheWorfEffect: {{Downplayed}} (see PintSizedPowerhouse). It's implied that they can make Thor or Rodan work to beat them in a proper fight, but they wouldn't stand a chance at defeating Godzilla if they fought seriously in their second form.
325* YouCanTalk: A {{Kaiju}} being capable of direct communication is a new curveball for humanity, especially those who didn't know beforehand that the Titan in question is a TranshumanAbomination (itself a phenomenon that's outright ''unprecedented''); prompting reactions of bewilderment, shock and awe when humans first hear Viv and San's speaking voices, or when word of mouth about it starts spreading online.
326* YouDontLookLikeYou: {{Downplayed}}, but Viv and San's second fused form is quite distinct appearance-wise from the Toho films' original incarnation of Monster X. [[spoiler:Completely {{subverted}} by their final form]].
327[[/folder]]
328----
329
330!!Dr. Vivienne Graham
331A prominent Monarch scientist who had a close relationship with Dr. Serizawa. She was SwallowedWhole 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.
332
333[[folder:Tropes A-M]]
334* ActionGirl: Due to her Titan transformation and all the combat that comes with such a life, she's now an Action Female Kaiju.
335* ActionMom: As a Titan, she becomes this after [[spoiler:adopting Manda]].
336* AdaptationalFriendship: She's more explicitly close to several of Monarch's other top brass whom she was never explicitly shown to be anything more than colleagues to in the [=MonsterVerse=] materials; namely Drs. Ilene Chen and Rick Stanton, Sam Coleman, and Colonel Diane Foster.
337* AffectionateNickname: Somewhat. San usually calls Vivienne "sister" (after merging with her) and "Bone Singer".
338* AfraidOfTheirOwnStrength: She's afraid both of hurting humans if she so much as touches them due to her {{Kaiju}} size, and she's also wary of getting blood-drunk when using her and San's "storm".
339* AllGirlsWantBadBoys: In "Ain't That a Kick in the Head", Ling jokingly says that Vivienne's always had a thing for "bad boys in leather", [[spoiler:referring to Monster X's chemistry with Rodan]]. Vivienne grouses that Ling knows her too well.
340* AmbiguouslyBi: There's a casual hint in Chapter 10 that she's bisexual, which [[https://hrodvitnon.tumblr.com/post/666381938165268480/ Word]] [[https://hrodvitnon.tumblr.com/post/694341867251302400/ of God]] has further supported since. The ambiguity disappears in "Ain't That a Kick in the Head".
341* AmicableExes: [[https://hrodvitnon.tumblr.com/post/666381938165268480/ The author]] has supported the suggestion that Vivienne and Ling Chen were once in a relationship, and they remained on friendly terms after breaking up, [[spoiler:with the ''Fanfic/AbraxasEmptyFullness'' one-shot "Ain't That a Kick in the Head" confirming that to be the case]].
342* ArbitrarySkepticism: She works for an organization that studies ancient {{Kaiju}}, but she never believed that alien life -- at least not of the technologically super-advanced variety -- might exist, until San tells her of how he and his brothers exterminated such a species in Chapter 10.
343* AscendedExtra: She's one of the two main {{protagonist}}s of the story with a healthy and delightful amount of characterization and CharacterDevelopment to go with it, alongside San. In Film/MonsterVerse canon, she's been considered by the fandom a SatelliteCharacter and a case of They Wasted a Perfectly Good Character (especially after she was killed off in ''King of the Monsters''), and Hrodvitnon is a Creator/SallyHawkins fan who is openly on the [=TWAPGC=] train.
344* BabyFactory: It's revealed in Chapter 16 that [[spoiler:Ghidorah intends to forcibly impregnate her with a "Death-Child"]].
345* BackFromTheDead: She technically was temporarily dead after being SwallowedWhole 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]].
346* BadassBoast: She has the below one for Jonah when she and San are about to escape containment in Chapter 6. See the General folder for another example.
347--->"''Did you think us defeated? Broken down to be your tool? Did you think yourself like Odin, all-seeing and all-knowing? Binding us like Fenrir, foretold to bring about great destruction at the time of Ragnarök? For all his wisdom and insight and knowledge, did it ever occur to Odin that by binding the wolf he was only creating a self-fulfilling prophecy? Fenrir's sons will devour the sun and moon, Gleipnir will break, and Fenrir will have his vengeance on Odin. This fetter will break...''"
348* BeautyToBeast: She's acknowledged as having been a looker when she was human, whereas her and San's first form post-fusion is a real case of BodyHorror (though her face is still recognizable upon close inspection). The trope is later somewhat reversed: Viv and San's complete second form is even more bestial than their first form, yet notably more beautiful.
349* BeCarefulWhatYouWishFor: PlayedWith. Canon [[AllThereInTheManual Manual]] materials state she always sought a life of adventure, and it's mentioned in [[https://www.fanfiction.net/s/13357907/12 Chapter 12]] that she used to hope she could wake up at Castle Bravo to seeing Godzilla. Both those things are certainly recurring parts of her life now.
350* BecauseYouWereNiceToMe: Whilst she is San's MoralityPet, the lengths he goes to caring for her throughout their imprisonment (which is far more than their human captors are giving her) influence her bonding with him in turn.
351* BeingTorturedMakesYouEvil: She's on the receiving end of attempts to [[InvokedTrope invoke]] this. Jonah attempts to psychologically break her via ColdBloodedTorture, as does [[spoiler:Ghidorah]] later on.
352* TheBerserker: This is the state she's often gone into in fighting [[spoiler:until she and San reach their final form]]. Because it's uncontrollable and she tends to lose herself, she and San agree that she needs to learn to control it.
353* BewareTheNiceOnes: When she was human, she wasn't easily angered but it was frightening when someone actually succeeded in pissing her off. Her temper is certainly no less fierce after her transformation into part of Monster X, plus she tends to get angry easily due to her TraumaCongaLine and PTSD.
354* BigNo: When she freaks over [[spoiler:Susan Graham]]'s presence at Yonaguni in Chapter 15, and when she realizes [[spoiler:[[BabyFactory what Ghidorah is going to do to her first]] before it assimilates her]].
355* BigShutUp: She throws a couple of these when someone derides her relationship with Serizawa.
356* BlankStare: She playfully gives Madison a joking one when the latter teasingly asks her to perform a dance in [[https://www.fanfiction.net/s/13357907/8 Chapter 8]].
357* BloodFromTheMouth: Besides the example she shares with San (see above folder), blood ''geysers'' from her mouth during the HeroicRROD.
358* BondVillainStupidity: {{Inverted}} by her in Chapter 6. Drunk with bloodlust, she almost tries to blast [[DiscOneFinalBoss Jonah]], then decides against it in favor of letting him lead her and San to his dirty little secret and killing him after. Had she gone through with the former option instead of picking the latter, Jonah might not have gotten away there and then.
359* BreakTheCutie: She endures this over the course of the story’s first five chapters, leading to her [[TookALevelInBadass Taking A Level in Badass]] – and her TraumaCongaLine isn’t over yet.
360* BrokenTears: Honestly, after the last thing she clearly remembers is running and screaming for her life amidst Ghidorah's awakening before she's suddenly woken up somewhere else transformed into a malformed, pain-wracked monster; is it any surprise in the ''slightest'' that tears are lining down from her eyes for hours? And this certainly isn't the ''last'' time Vivienne ends up crying in such a way during the fic.
361* BusmansVocabulary: A mild case, but it shows at times that she's affluent in mythology and has an interest in the past.
362* CessationOfExistence: It's revealed [[spoiler:in Chapter 5]] that she apparently experienced complete oblivion when she was [[OnlyMostlyDead temporarily dead]]. It's [[https://hrodvitnon.tumblr.com/post/637986068089716737/ implied by the author]], and [[spoiler:confirmed in Chapter 17 and "Sermones ad Mortuos"]], that this is not permanent after death for beings InUniverse, but rather is an intermediary stage preceding [[{{Reincarnation}} the next life]].
363%%* CondensationClue
364* TheConscience: She seems to mainly serve this function among the duo, whereas San tends to be True Neutral when it comes to aiding others.
365* ContrastingSequelMainCharacter:
366** The human protagonists of ''Film/Godzilla2014'' and ''Film/GodzillaKingOfTheMonsters2019'' (Joe, Ford and Mark) were grappling with the death of a child or spouse which happened to them years before the story's main time frame, and they'd isolated themselves (in Joe and Mark's cases) and strained their relationships with their loved ones. Vivienne is instead [[MovingBeyondBereavement grappling with the death of a]] ParentalSubstitute which she finds out about during the story (making her raw grief a lot more fleshed-out and understandable), and she remains sociable with Titans and humans when she and San start communicating with them. Furthermore, Vivienne here is a {{Metamorphosis}} instead of just a human, she's female instead of male, and instead of being just a soldier (Ford) or an ex-scientist (Joe and Mark), she's an ex-scientist turned {{Kaiju}} warrior.
367** Godzilla is ancient, experienced, well-versed in how to use his strengths and weaknesses, and he's famous among humans and Titans around the world. Vivienne is new to her Titan body, she's female instead of male, and whilst she was somewhat FamedInStory she was mostly just seen as an extension of Serizawa before she got transformed into a Titan.
368* CruelAndUnusualDeath: Her initial death when Ichi/Eldest Brother ate her alive. It's confirmed she didn't die right away when he ate her, and she was aware of what was happening.
369* CryLaughing: She responds this way when informed of [[BusCrash Admiral Stenz's death]], in Chapter 11.
370* TheCuckoolanderWasRight: InUniverse. Tejada initially thought Vivienne was a loon because of her worshipful attitude to Godzilla, but realizes Vivienne's notes are right about Ghidorah's BrownNote.
371* DayHurtsDarkAdjustedEyes: A variation. When she and San are first reborn as TwoBeingsOneBody, after months gestating in a "womb" inside San's old head, Vivienne reacts with pain to the indoor artificial lighting she's greeted with.
372* DeadpanSnarker: She has a few moments.
373* DeathAmnesia: She doesn't know whether or not she literally died when she was SwallowedWhole by Ghidorah, until Chapter 5. {{Justified}}, as in this universe, CessationOfExistence occurs after death.
374* DeathByIrony: Jonah lampshades the cruel irony of her death by Ghidorah, the very Titan whose containment Vivienne was in charge of monitoring.
375* DeathByOriginStory: She's reborn as part of Monster X at the story's start, following her [=MonsterVerse=] canon death in ''Film/GodzillaKingOfTheMonsters2019''.
376* DeerInTheHeadlights: She has this reaction when she first sees [[spoiler:[=MaNi=]/Elder Brother]] and her PTSD triggers, in Chapter 15.
377* DeityOfHumanOrigin: After being transformed from a human into half of a TwoBeingsOneBody Titan, she and her brother are considered as much a PhysicalGod as the other Titans. She lampshades this in [[https://www.fanfiction.net/s/13357907/12/ Chapter 12]].
378* DespairSpeech: She has this when she's in the midst of her HeroicBSOD over Serizawa's death:
379--->'''Vivienne:''' It matters because ''you'' [San] might be able to come back, but ''we'' [humans] can't. Even if we did get out of here, we can never do what you did with me. There's nothing left of him.\
380'''San:''' nothing?\
381'''Vivienne:''' Nothing! My memories are all I have left of him.
382* DidYouJustRomanceCthulhu: [[spoiler:She becomes mated to the ancient Titan Rodan,]] albeit only after she herself has become a TranshumanAbomination Titan.
383* DisappearedDad: The matter of her biological father who died before she was born is sometimes PlayedForDrama, including in relation to how it influenced her ParentalSubstitute bond with Serizawa.
384* DoesNotKnowHerOwnStrength: She has a claw variation of this upon her rebirth as half of Monster X. Not yet aware of her new Titan body's strength or sharp claws, she accidentally guts one of Jonah's men and [[HalfTheManHeUsedToBe rips him in half]].
385* EarAche: A horn variation. San gets so desperate to snap her back to her senses that he resorts to biting her horns during her psychotic episode, in Chapter 9. Vivienne also gets bitten on the horns by a frustrated [=MaNi=]/Elder Brother in Chapter 16.
386* EldritchTransformation: {{Downplayed}}. San semi-unintentionally transforms her from a mere human smaller than a Titan's tooth into an unnatural-looking MonstrousHumanoid with BodyHorror, a second set of ingrown teeth, and a second head growing from the back. Viv and San's second {{Metamorphosis}} grants them a much more stable Titan form.
387* EloquentInMyNativeTongue: According to [[https://hrodvitnon.tumblr.com/post/696115062838067200/ Word of God]], she can speak scraps of Mandarin but her overall command of the language is awful.
388* EtTuBrute: After she finds out about her friend Emma's betrayal and crimes, it's clear in later chapters when Emma gets mentioned that Vivienne has taken it very personally.
389* EyeColourChange: Her hazel eyes turn a [[GlowingEyesOfDoom burning]] [[RedEyesTakeWarning red]] when her and San's powers kick in. See the above folder for more details.
390* EyeScream: InUniverse, Vivienne balefully remembers one of Jonah's {{Mook Lieutenant}}s shooting her in her eye, long after it occurs in Chapter 4. It's revealed in Chapter 6 that when she was human, she at one point suffered a bloodshot eye due to Ghidorah's psychic influence. See the above folder for another example.
391* {{Facepalm}}: She pinches the bridge of her nose in Chapter 9 when snapped out of an unpleasant reverie.
392* FaceYourFears: In Chapter 16, she [[spoiler:tears her way into [=MaNi=]/Elder Brother's mouth and throat to save San]], this despite her phobia of monstrous jaws due to her death in Antarctica.
393* FamedInStory: When human, she was one of Monarch's most famous/infamous members alongside Serizawa. After the hybrid she and San have become becomes known to the world, it draws a lot of public attention.
394* FamilyEyeResemblance: San notes that Vivienne's biological father had the same hazel green eyes as her.
395* FateWorseThanDeath: Ichi/Eldest Brother intended to inflict this on her when Ghidorah began transforming her. Even with her and San's separation from Ghidorah, she agrees that it would've been more merciful if Ghidorah had just killed her outright. Word of God [[https://hrodvitnon.tumblr.com/post/688985016945000448/ here]] makes it clear that Vivienne becoming [[spoiler:Ghidorah's fourth head]] would very much be this trope, filled with no end of abuse, MindRape, and a [[SlowlySlippingIntoEvil slow]] BeingTorturedMakesYouEvil.
396* FauxFlame: [[https://hrodvitnon.tumblr.com/post/647304890909065216/ The author's artwork]] portrays Monster X's red-themed bioluminescence burning bright enough to create this effect during the events of Chapter 16.
397* FireIsRed: She produces a FauxFlame effect with Monster X's bio-electrical powers in Chapter 16. {{Justified}} due to the [[YellowLightningBlueLightning red coloration]] of Monster X's lightning powers.
398* FirstEpisodeResurrection: The fic's opening establishes that after Ghidorah's middle head ate Vivienne during the events of ''King of the Monsters'', the left head revived her with her mind intact, in a womb inside his neck, and he's been regenerating and transforming her inside his severed head so the two of them can become TwoBeingsOneBody as a Titan.
399* FirstNameBasis: She's referred to by her first name by San (when he uses her name) and by the Russell's in particular.
400* FlatWhat: This is her mental first response when Mariko gives her the first clear hint that Serizawa is dead in Chapter 4.
401* {{Foil}}:
402** To Alan Jonah. They've both tragically lost a loved one, but Vivienne is coping with the loss whereas Jonah has allowed it to turn himself into something evil. Vivienne died committing a HeroicSacrifice to save her friend whereas Jonah sacrificed [[EvenEvilHasLovedOnes his]] to save himself, both during the events in Antarctica. Ghidorah's lingering influence threatens both of them with SanitySlippage, but Jonah [[spoiler:slips too far and too soon to escape his fate]], unlike Vivienne. Both ultimately [[spoiler:become fused to Ghidorah hybrids]], but ironically, what's left of Jonah's mind sees himself as [[SmugSnake more valuable to]] [[spoiler:[[SmugSnake Ghidorah]]]] [[SmugSnake than he really is]], whereas Vivienne is the AntiAntichrist and is the one [[spoiler:Ghidorah]] ''really'' wants.
403** To Thor. They both tragically lost a loved one (Vivienne's father-figure, Thor's [[spoiler:son]]), but [[spoiler:whereas Vivienne's will to live is wholly reinvigorated by San, Thor has implicitly been waiting to rejoin his lost loved ones in death]]. Vivienne's an ArtificialHybrid whilst Thor is a [[MixAndMatchCritters Mix-and-Match Critter]]. Vivienne is curious about the old ways and rediscovering them, while Thor is a relic of said old ways.
404* ForcedToWatch: She's helplessly forced to watch as [[spoiler:[=MaNi=]/Elder Brother almost kills San in front of her]], in Chapter 16. See the above folder for another example.
405* ForgottenFallenFriend: Jonah suggests while trying to break Vivienne down that she's this to Monarch, in Chapter 5. [[spoiler:{{Subverted}}]] two chapters later.
406* FourIsDeath: [[spoiler:Ghidorah's EvilPlan for her is to turn her into its fourth head ("dreaded number four", she notes). Made all the more fitting by the fact Ghidorah's three heads all have Japanese numerals as their nicknames]].
407* FriendToAllChildren: Besides her relationship with Madison, she used to babysit Ilene's twin daughters, who regard her fondly. A deleted scene showed her scaring off a mercenary who was stalking two DisposableVagrant children with but a DeathGlare.
408* GallowsHumor: She tries using humor to cope with her trauma at times when it's about to surface, though it doesn't work perfectly.
409* GoMadFromTheIsolation: Spending months locked in a sealed chamber with insomnia and no track of time gets to her, although San helps her cope and subvert the effects by being talkative and curious.
410* GrinOfRage: In her human life, Vivienne was known to smile a smile "that shows a little too many teeth and belongs on someone who could scare a serial killer into rethinking their life choices" when someone managed to push her to true fury. Vivienne retains this trait as [[TwoBeingsOneBody half of]] Monster X, putting it on display when she's utterly ''pissed'' at [=MaNi=]/Elder Brother.
411* HappyPlace: In Chapter 4, she tries to drown out Guard [=B-04=]’s abuse and avoid thinking of Ghidorah by reciting geological time periods.
412* TheHeart: In her human life, she was beloved by her colleagues in the [[TheTeam Monarch top brass]] for her charm, humor and disarming presence. Vivienne and Ilene bonded by using runes as a secret code, Vivienne and Rick could match each-other's wits, and Sam found her presence medicinal for his anxiety.
413* HeldGaze:
414** She locks eyes with Madison in an attempt to invoke the Platonic version of this trope, but it enables Madison to see in Vivienne's eyes how mentally wounded she really is, in Chapter 8.
415** Vivienne and [[spoiler:Godzilla]] share a few Platonic gazes where the latter is attempting to comfort the former.
416** The Antagonistic version happens when she and [[ItsPersonal Alan Jonah]] lock glares in Chapter 13.
417** The Platonic version occurs between her and Manda when they first meet. [[spoiler:Manda makes direct eye contact with Vivienne, and Vivienne thinks she sees a momentary flash of recognition in Manda's eyes, hinting that the latter might be Serizawa reincarnated with some unconscious fragment memory of her]].
418** [[spoiler:She ends up locking gazes with Susan when mother and daughter reunite in person in Chapter 15]]. And the look in Vivienne's eyes is nothing short of anguished.
419** See the other folders for more examples.
420* HeroicBSOD:
421** 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=]...
422** In Chapter 16, she's initially thrown into catatonia by her PTSD, forcing San to initially do all the defending-their-life work.
423* HeroicResolve: In Chapter 16, [[spoiler:[=MaNi=]/Elder Brother ripping San's head off and attempting to devour him]] triggers a fierce case of this in Vivienne.
424* HisStoryRepeatsItself: {{Averted|Trope}}. The author [[https://hrodvitnon.tumblr.com/post/699677927317569536/ notes]] that effectively enduring a mimicry of her original death by Ichi's jaws [[spoiler:when she leaps in [=MaNi's=] gullet to save someone she cares about from the same kind of death]], has ''not'' cured Vivienne's {{trauma button}}.
425* HistoryRepeats: It's eventually revealed that she's at risk of this happening to her if Ghidorah's plan for her comes to fruition. [[spoiler:Getting forcibly fused to another being to form a multi-headed Titan and furthermore being "caged" and tortured, is also Ghidorah's origin story, which culminated in Ghidorah eventually becoming the evil OmnicidalManiac it is]].
426* HoldingHands: In Chapter 8, Madison grasps Monster X's knuckle tenderly when the Vivienne half reaches a hand out towards her for comfort. In Chapter 14, Ren grips Vivienne's gigantic hand apologetically [[spoiler:after he finds out about Monster X's true nature]]. In Chapter 15, Vivienne desperately grasps Godzilla's finger, trying to warn the Titan that she spent much of her human life worshipping [[spoiler:about the Many targeting Castle Bravo]]. See the General folder for more examples.
427* HonoraryAunt: Besides being viewed by Madison as a ParentalSubstitute (see below), Madison also calls her "Aunt Viv".
428* HornsOfVillainy: {{Inverted}}. Getting turned into a half-Ghidorah hybrid eventually grants her horns on her own head like San's, but she's still a benevolent and kind-hearted creature.
429* HowlOfSorrow: Gives a particularly horrific one after learning of Serizawa's death. It was literally heard by Titans as far as halfway across the northern hemisphere. This could also overlap with DeathWail, considering that she and San are a MonstrousHumanoid capable of vocalizing with humans at this point.
430* IllKillYou: She mentally screams as much in graphic detail a couple times, when she ''really'' gets pissed off by her loved ones being seriously threatened.
431* InhumanHuman: Particularly in her and San’s first hybridized form, where she’s essentially revived from being OnlyMostlyDead but is no longer human and their first form is a FlawedPrototype with BodyHorror.
432* InSeriesNickname: She's known by Ziyi and Yong as "Dinosaur Lady".
433* TheInsomniac: Vivienne's memories reveal this trope was {{invoked}} on her by the frozen Ghidorah's BrownNote while she was staying at Outpost 32. After being reborn fused to San, she's initially rendered insomniac. See the General folder for another example.
434* InTheBlood: Her Bone Singer potential is apparently hereditary and likely came from a distant ancestor or two (as noted by [[https://hrodvitnon.tumblr.com/post/691624167475478528/ Word of God]]). It's also hinted that her lifelong [[TheXenophile Xenophilia]] for Titans and fossils might be influenced by her heritage.
435* IShallTauntYou: [[spoiler:She tries to bait Jonah, who's attached to one of the Many's {{Mind Hive}}s, in Chapter 13, to get a psychological advantage]].
436* ItWasAGift: Like in the ''King of the Monsters'' official novelization, Vivienne received a Yapese pendant with a carving of Godzilla on it from Serizawa on her thirtieth birthday. San views her memory of the event amidst his HeelRealization.
437* IWillFindYou: {{Inverted}}. Once again seeing her friends, her mother and Serizawa (before she learns of his death) who don't know of her revival is what motivates her to escape her and San's imprisonment by Jonah.
438* {{Jawbreaker}}: {{Downplayed}} in [[https://www.fanfiction.net/s/13357907/2/ Chapter 2]] when artillery from Jonah's mercs badly damages her jaw, barely slowing her down.
439* KidsLoveDinosaurs: She apparently had a passion for dinosaurs throughout her childhood which she retains as an adult.
440-->It's her favorite childhood memory. […] Her passion for dinosaurs went above and beyond a child's fascination or obsession, as her frantic mother discovered after rushing to the museum and finding her sound asleep at the foot of a brontosaurus skeleton.
441* LastNameBasis: Slightly {{downplayed}}. She's frequently but not always referred to by her last name by other Monarch operatives.
442* LaughingMad: She ends up toeing this in Chapter 16 when [[spoiler:[=MaNi=]/Elder Brother trying to kill San]] makes her flip.
443* LikeADaughterToMe: To Serizawa, like in canon. Learning of his death sends her into a ''severe'' [=BSoD=], and she goes as far as calling him "father" in both Japanese and [[AnimalTalk Kaiju Talk]] afterward.
444* LikeBrotherAndSister: Vivienne's father-daughter relationship with Serizawa is a variation. It's mentioned in Chapter 4 that Monarch operatives debated whether or not the nature of their closeness was romantic.
445* LikeMotherLikeDaughter: Though there are distinctions, it turns out she and her mother are both BewareTheNiceOnes, both have an interest in nature, and it's from her that Vivienne got her sharp-tongued side.
446* LipLosses: In Monster X's first form, her lips are partly shredded and gone at the sides due to developing ingrown, Ghidorah-like fangs.
447* LittleNo: She gives a string of the first type when refuting [[spoiler:Ghidorah]] with a NotSoSimilar speech (see below).
448* LockedOutOfTheLoop: Having been comatose and regenerating for half a year, she's at first out of the loop on multiple events that happened after her death in Antarctica. There are still some details she's only now catching up on.
449* MadnessMantra: This is a recurring mental phrase when her PTSD is really kicking into high-gear:
450--> "''DON'T LOOK UP YOU'LL DIE IF YOU LOOK UP''"
451* MamaBear: Her blood boils at the thought that Ghidorah hunted Madison from sport in Boston. And Manda is no exception.
452* MayflyDecemberFriendship: It's indicated by [[spoiler:Ghidorah]] in Chapter 14 that following her Metamorphosis, she'll outlive all her human friends.
453* MeaningfulName: Her name is noted in Chapter 1 to mean "alive", quite fitting in the context of what happens to her in this story. See the other folders for more examples.
454* MessianicArchetype: {{Lampshaded}} a couple times. Vivienne coming BackFromTheDead is compared to Jesus, and it fits. She began her life walking amongst humanity, she died in a HeroicSacrifice and descended into hell (or into [[SatanicArchetype the Devil]]'s jaws to be more precise), she [[BackFromTheDead returns from the dead]] to the surprise of her Apostles (her Monarch colleagues and the Russells), and she ascends to godhood ({{Physical God}}hood as a hybrid Titan). Adding to the "Twelve Apostles" archetype, Emma can be seen as the Judas for betraying Vivienne despite the latter's friendship in such a way that instigated Vivienne's death and resurrection. Like Jesus, Vivienne has a mother, an absent (not walking the Earth) biological father who she takes after in some way, and a [[ParentalSubstitute father figure (Serizawa)]]. Monster X is also initially met with stigma from some of humanity before [[spoiler:Viv and San's final rebirth]]. Vivienne even has the fact that she worships and is guided by the "God" of this setting ([[BigGood Godzilla]]) going for her.
455---> '''Mark Russell:''' Jesus.\
456'''Vivienne: ''' ''[[DeadpanSnarker yeah?]]''
457* MirrorCharacter:
458** It turns out imprinting on a ReplacementGoldfish to ease the tragic loss she suffered is something Vivienne and Thor have in common. Both are technically hybrids (an ArtificialHybrid and a [[MixAndMatchCritters Mix-and-Match Critter]]), and they're both only just getting up-to-date on what's happened in the world while they were away.
459** Vivienne and Manda are both "newborn" Titans [[spoiler:and possibly both formerly-human]].
460** And to [[spoiler:Susan, her own mother]]. Depending on [[HappilyAdopted Manda]]'s MaybeMagicMaybeMundane, Vivienne and [[spoiler:Susan]] might both [[spoiler:have a human-turned-Titan offspring who happens to be a loved one they thought dead and mourned in some form]]. Both of them also fight to hold themselves together through their grief despite how much it's taken out of them.
461* MoeGreeneSpecial: One of Jonah's mooks shoots her in the eye, and although it regenerates, the memory sticks with her.
462* MonstrousCannibalism: {{Defied}} when she, still coming to terms with what she's become, vehemently rejects San's suggestion that she eat Jonah's troops in Chapter 4.
463* MoralityPet: She's this to San, having a positive influence on his character growth since he fused with her, and it's because of her that San becomes determined to be better than Ghidorah. [[spoiler:She's even able to get San-2/Youngest Brother to pull a RedemptionEqualsDeath after TalkingTheMonsterToDeath]].
464* MoreTeethThanTheOsmondFamily: After fusing with San, she has two sets of teeth: a universally sharp front set, and a more human-like rear set with canines and molars. See the General folder for more details.
465* MovingBeyondBereavement: Throughout most of the main fic, she's still in mourning over Serizawa's death on top of all the other TraumaCongaLine shit she has piled on her. See the General folder for another example.
466* MyInstinctsAreShowing: {{Inverted}}, as she adapts to having an inhuman body, but does still retain some human-like body language and also a couple individual physical cues from when she was human. According to [[https://hrodvitnon.tumblr.com/post/686616424688599040/ Word of God]], it'll take her a while to adjust to ''feeding on'' radiation instead of fleeing it.
467[[/folder]]
468
469[[folder:Tropes N-Y]]
470* NiceGirl: She's widely regarded as a kind person by her peers, who all benefitted in some way from her company. She's still a compassionate person after her resurrection as part of Monster X, but she's lost the "psychologically well-balanced" part entirely due to her TraumaCongaLine.
471* NoJustNo: In "Ain't That a Kick in the Head", finding out that some of her Monarch colleagues used to think she'd get together with Mark for Madison's sake gets a very flat "No" out of Vivienne.
472* NotAfraidToDie: PlayedWith. San notes in Chapter 5 that she's not afraid of dying anymore after her first experience.
473* NotSoAboveItAll: When she was human, despite her reserved and job-oriented demeanor, she apparently wasn't above making friendly mischief with some of her colleagues.
474* NotSoSimilar: She thinks this about herself and Ghidorah (specifically Ichi/Eldest Brother) during an exchange with an enemy in [[https://www.fanfiction.net/s/13357907/14/Abraxas Chapter 14]]:
475--->[[spoiler:'''Ichi''']]: [[spoiler:'''OUR PAST IS YOUR FUTURE.''' [...] '''AND IN A THOUSAND YEARS, WHO WILL KNOW YOU AS YOU WERE? BUT WE, YOU AND I. WE ARE REFLECTIONS OF EACH OTHER. WE ARE ETERNAL.''']]\
476'''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]!''
477* OhCrap: Besides the example she shares with San (see above), she has a few of her own:
478** She's horrified when Jonah telling her she's "heard it [Ghidorah]" makes her realize what the nature of Jonah's SanitySlippage is, prompting her to desperately plead with Jonah for a moment to get his men away from San's old head, in Chapter 6.
479-->What does he...\
480''[flashes back to an Outpost 32 operative acting similarly disturbed]''\
481...oh... ''fuck''...
482** When she realizes [[spoiler:just what Ghidorah is going to do to her ''before'' it assimilates her as a fourth head]], she is ''horrified'', screaming a BigNo, and her desperation to escape increases; in Chapter 16.
483* OnlyMostlyDead: She was naturally presumed dead after being SwallowedWhole by Ghidorah. Whilst it's confirmed that she did indeed die from massive physical trauma during this event, Ghidorah brought her BackFromTheDead inside it within a relatively short time afterwards.
484* OOCIsSeriousBusiness: When she was human, she was not easily driven to anger, [[BewareTheNiceOnes but it was frightening when someone succeeded]]. After she becomes part of Monster X, everyone who knew her when she was human can tell by her eyes how much of a ShellShockedVeteran she now is. See the General folder for another example.
485* PainfulTransformation: ZigZagged, and somewhat {{defied}} by San. Vivienne is comatose throughout her and San's slow transformation into a TwoBeingsOneBody hybrid, but there are still a few episodes where she experiences enough pain that it gets through to her unconscious mind until San sedates her. Post-rebirth, she's agonized when San's head suddenly develops further on their body in Chapter 4.
486* ParentalSubstitute:
487** She was this towards Madison, who admits a few times (including to Vivienne herself) that she wished Vivienne would've become her mother if things had happened differently. Mark and others at Monarch are aware of it as well.
488** She can also be seen as a form of this towards San, in contrast to his brothers -- showing him affection unlike his brothers ever did, and forming a strong brother-sister bond with him.
489* PastExperienceNightmare: It gets mentioned that she regularly has nightmares of Ghidorah due to her PTSD from Ichi/Eldest Brother killing her.
490* PitifulWorms: A heroic case. She isn't immune to mentally calling Jonah and/or his men (who caused her and San a lot of pain) "insects" when she's sufficiently enraged and is acting.
491* PlaguedByNightmares: A symptom of her severe trauma is that she's chronically plagued by nightmares which include Ghidorah and her death in them.
492* PlatonicLifePartners: Besides her relationship with San (see above folder), her relationship with [[ParentalSubstitute Dr. Serizawa]] beforehand was also this intimate. She's deeply ''distraught'' over his death.
493* PoorlyLitPareidolia: In Chapter 16, she briefly hallucinates stalagmites and stalactites as ScaryTeeth and gore. {{Justified}} by [[spoiler:Ghidorah]] telepathically messing with her head.
494* PowerUpgradingDeformation: Initially, in Monster X's first form which has granted her Ghidorah's [[ShockAndAwe bio-electricity]] and HealingFactor along with San’s mind while causing BodyHorror. [[InvertedTrope Inverted]] during Vivienne and San's second {{Metamorphosis}}.
495* ProHumanTranshuman: She initially refuses to kill other humans (though this fades after she [[TookALevelInBadass Takes A Level in Badass]]), she still actively wants to stay in touch with her humanity despite her transformation, and she seeks as much interaction with her human loved ones as a Kong-sized chimera Titan can have.
496* ThePromise:
497** She promises San that she'll always be with him in Chapter 6. [[spoiler:She manages to keep this promise when they're literally almost ripped apart from each-other near the fic's climax]].
498** Later, she tears up over the fact that she made a promise to her mother that she'd stay safe when she was human, and then [[SwallowedWhole Antarctica happened]].
499* {{Protectorate}}: San initially considers it his responsibility to protect and care for Vivienne. After she [[TookALevelInBadass Takes A Level in Badass]], she and San become mutually skilled at defending themselves together.
500* PsychicNosebleed: Besides the one that both heads suffer as part of a BloodFromEveryOrifice (see above folder), it's mentioned in Chapter 6 that when Vivienne was still human, the frozen Ghidorah's PsychicPowers caused a variation in the form of her eye turning bloodshot.
501* PuppyDogEyes: PlayedWith. Ren Serizawa thinks in [[https://www.fanfiction.net/s/13357907/14 Chapter 14]] that when she was human, her gaze tended to have a "kicked puppy" look when she was emotionally hurt.
502* QuizzicalTilt: She has a tilt of curiosity in Chapter 3 when she hears the new visitor Jonah has brought to her using her name. She has another one in Chapter 5 when listening to [[spoiler:Thor's call]]. In Chapter 9, she has a tilt of confusion when she realizes Mothra won't be teaching her how to use her and San's powers.
503* RageBreakingPoint: She hits hers when Jonah's MookLieutenant finally pushes her too far in Chapter 4, at which point she explodes whilst San takes over their body and paints the walls with blood.
504* RapeIsASpecialKindOfEvil: In [[https://www.fanfiction.net/s/13357907/16/Abraxas Chapter 16]], she finds herself sicker than ever before (and that is ''saying something'' considering all that she and San have been through), when she realizes that [[spoiler:Ghidorah and [=MaNi=]/Elder Brother wholly intend to inflict the R-word on her to break her down further]].
505* ReflectiveEyes: In Chapter 7, her eyes reflect the bioluminescent light of Mothra's insects. See San's folder for another example.
506* RelativeButton: The Many successfully goad her to rage by threatening [[spoiler:her mother]] among others. [=MaNi=]/Elder Brother and [[spoiler:Ichi/Eldest Brother]] make a point of sadistically taunting her when they [[spoiler:try to permanently kill San]].
507* TheReliableOne: She was apparently this to Monarch when human, being MarriedToTheJob on top of her NiceGirl relations with her colleagues.
508%%* ReluctantWarrior
509* ReplacementGoldfish: [[spoiler:San's EvilDoppelganger]] tries getting to Vivienne in [[https://www.fanfiction.net/s/13357907/11 Chapter 11]] by claiming that her emotional bond with her brother is just a Replacement Goldfish for losing Serizawa.
510* ReportsOfMyDeathWereGreatlyExaggerated: It isn't until several chapters in that Monarch discover Ghidorah eating her was not the end, and the world at large remains unaware of her true fate for longer.
511* RoarBeforeBeating: Besides her and San's shared examples above; she unleashes her own one when she starts retaliating against [[spoiler:[=MaNi=]/Elder Brother for ripping San's head from her and moves to rescue San]], in Chapter 16.
512* RoaringRampageOfRevenge: Her UnstoppableRage in Chapter 6 could count as a brief one for her and San.
513* SadClown: She uses humor as a coping mechanism especially while suffering from psychosis, and makes sarcastic, darkly comic observations even in the heat of battle.
514* SanitySlippage: She's teetered on this a few times due to her PTSD (see ShellShockedVeteran).
515* SensoryOverload: Downplayed. The first time she directly views San's memories, she feels painfully overwhelmed by how all his senses processed everything in the memories in much greater detail than human senses. She fares better the second time San lets her her see the world through his heightened senses than she did during the first time.
516* ShellShockedVeteran: Her experience of being EatenAlive has turned her into this, exhibiting definitive signs of PTSD. Her TraumaCongaLine hasn't done much to help either.
517* SilenceOfSadness: Mariko notes that Vivienne, severely traumatized by what's happened to her and her current situation, is usually very quiet and doesn't speak while she and San are held captive by Jonah's mercenaries. See the other folders for more examples.
518* SlasherSmile: She was known to produce this expression when she was human as a warning sign when someone had ''seriously'' pissed her off. In Chapter 16, she gives [=MaNi=]/Elder Brother a dangerous smile during her HeroicResolve. See the General folder for another example.
519--->''[...] the smile Vivienne would make on those rare occurrences she'd been goaded to genuine cold fury, a smile that shows a little too many teeth and belongs on someone who could scare a serial killer into rethinking their life choices.''
520* SmallParentHugeChild: Her elderly mother [[spoiler:and San's adoptive mother]] Susan was shorter than her daughter even when Vivienne was human (bear in mind that Vivienne herself wasn't very tall), to say nothing of after San fuses with Vivienne to form a 100-foot TwoBeingsOneBody Titan.
521* SomethingOnlyTheyWouldSay: PlayedStraight when Monarch become aware of Monster X's true nature and Madison asks Vivienne a series of questions only she would know the answers to. Later, [[spoiler:Susan Graham]] realizes the two-headed creature is Vivienne when [[spoiler:she]] hears San's voice reciting the Elder Futhark and Vivienne's voice reciting Frere Jacques.
522* SpeaksFluentAnimal: She possesses a hereditary ability which would’ve enabled her to mutually communicate with Titans when she was human if the practices for learning to harness it were still around. After being transformed into part of Monster X, [[https://hrodvitnon.tumblr.com/post/631249528601935872/ with the aid of her neural link to San coupled with her hereditary potential]], she can fluidly understand what other Titans are saying and vice versa.
523* StagesOfMonsterGrief: PlayedWith. She's at first dismayed that her transformation into Monster X doesn't turn out to be a nightmare. She eventually forgives and grows close to San, but she hates Ghidorah for psychically haunting her before her transformation, among its other evil acts. By [[https://www.fanfiction.net/s/13357907/11 Chapter 11]], she's accepted that she physically isn't human anymore and is now officially one of the Titans, but she still fears becoming too detached from her former humanity.
524* StressVomit: She has one in Chapter 2 in response to her whole situation, shortly after becoming aware of San attached to her.
525* StrongFamilyResemblance: Her mother facially resembles her when she was human, but with softer features. Susan Graham in turn insisted that Vivienne took more after her father in appearance.
526* SurvivorGuilt: Her nightmare in Chapter 3 reveals she has a level of this, concerning numerous Monarch personnel and civilians who were killed by the [=MUTOs=], Jonah’s mercenaries and Ghidorah.
527* TaughtByExperience: San says that Vivienne is a quick learner despite her inexperience at being a Titan. She gets to prove her brother right during their sparring sessions with other Titans.
528* ThatLiarLies: When Mariko first informs her of Serizawa's death in Chapter 4, she at first responds: "You're lying."
529* ThereAreNoTherapists: She never gets a proper therapist to treat her PTSD, even after Monarch become aware that half of Monster X is a traumatized transhuman and they start holding communication sessions with her.
530* ThisIsUnforgivable: She already hates Jonah's guts, but when Vivienne finds out about [[spoiler:his PlayingWithSyringes]], [[UnstoppableRage her reaction]] makes it clear that she considers it to be Jonah's Moral Event Horizon; trying to chase him down and then reduce him to oblivion.
531* ThousandYardStare: She briefly does this in Chapter 9, and she probably did it several other times in the story when it was her or San's P.O.V. instead of an onlooker's being described to the reader.
532* TokenNonHuman: As a Monarch operative when she was human, she can be considered this after her transformation, although it's worth noting that as a Titan it seems she's now only connected to Monarch by socialization and communication rather than by profession.
533* {{Tomboy}}: She isn't known to have any particularly feminine interests, nor is her demeanor all that feminine.
534* TookALevelInBadass: She at first rebukes San's suggestions of deliberately killing other people, namely Jonah's personnel (even when said people are [[BullyingADragon really asking]] [[AssholeVictim for it]]). Several chapters later, she flies into an UnstoppableRage in which she shows Jonah's people who are stupid enough to stand in her and San's way no mercy; to say nothing how she verbally tore Jonah apart minutes earlier.
535* TragicKeepsake: According to the non-canon "[[https://archiveofourown.org/works/46831738/chapters/127672459 Come Little Monster, I'll Take Thee Away]]", Vivienne had a ''Literature/TheCallOfTheWild'' novel which previously belonged to her DisappearedDad, and she read it during her childhood before giving it to the Russells at some point.
536* TranshumanAbomination: A human transformed into a Titan. InUniverse, human characters are quite overwhelmed when they find out Monster X (or rather half of it) is formerly a human who was presumed dead.
537* TraumaButton:
538** It's advisable that one avoid directly reminding her of Ghidorah and triggering her PTSD, which can render her catatonic, or can at worst cause her to fully lose control of her half-Ghidorah violent impulses whilst temporarily forgetting where she is and who is around her. [[https://www.tumblr.com/hrodvitnon/699677927317569536/ The author]] has even stated that being {{eaten alive}} is Vivienne's worst fear after what Ichi/Eldest Brother did to her in Antarctica.
539** She's also traumatized enough by the events of ''Film/Godzilla2014'' that she steers clear of the Queen MUTO despite knowing the latter isn't the same specimen that slaughtered Monarch's Janjira outpost.
540* 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. And right after that, she suffers serious ColdBloodedTorture at Ghidorah's hands]].
541* TroubledFetalPosition: Besides the examples she and San have under the General folder, when she was human and Ghidorah was frozen, she was at one point reduced to curling into this position in the snow by exposure to Ghidorah's PsychicPowers.
542* TrustPassword: [[spoiler:Madison]] asks Vivienne a series of questions only she would know the answers to, to verify that one of Monster X's heads really is her.
543* {{Tsundere}}: [[https://hrodvitnon.tumblr.com/post/687445875345309696/ Word of God]] says that she and Rodan "will go full Tsundere mode" if their BelligerentSexualTension is pointed out to them.
544* TwitchyEye: After recovering from her psychotic episode in [[https://www.fanfiction.net/s/13357907/9/ Chapter 9]], she has a brief twitch in her brow.
545* UnskilledButStrong: Being formerly human, Vivienne attacks like an enraged primate in her first scuffle with other Titans, which isn't the best-suited mode of attack for her and San's new half-Ghidorah, quadrupedal physique, and she's all-round at first very inexperienced with her new Titan body. That doesn't stop her from single-handedly giving two Titans (plus her own brother half) a tough time holding her back when she has a psychotic episode, nor does it stop her later destroying a [[spoiler:Skullcrawler]] host of the Many with some aid from Rodan.
546* UnstoppableRage: She fully flies into one during her escape [[spoiler:when she learns what Jonah has been doing with the missing {{Disposable Vagrant}}s]], in Chapter 6. She flies into another impressive rage [[spoiler:when her loved ones are threatened]], in [[https://www.fanfiction.net/s/13357907/13/ Chapter 13]].
547* VengeanceFeelsEmpty: Implied in Chapter 13 [[spoiler:when she kills what's left of Jonah]].
548* VitriolicBestBuds: Maybe not "best buds" and it's a minor example, but in Chapter 14, Vivienne finds she's missed Lauren Griffin despite them considering each-other a nerd and a jarhead respectively.
549* VoiceChangeSurprise: Shortly after her and San's metamorphosis into their second form, Vivienne attempts to physically speak to a human but finds their new form is incapable of forming such vocalizations, her hand flying to her throat in surprise, in Chapter 8.
550* WhatIsGoingOn: She mentally asks as much the moment her unconscious mind stirs during her and San's first metamorphosis, in Chapter 1.
551* WhatYouAreInTheDark: The narrative lampshades that during the events in Antarctica, Vivienne could have left Mark behind to save herself when he was pinned by debris and the Osprey was falling into a crevasse, and no-one would have blamed her under the circumstances; but she stayed behind to save him anyway.
552* WithGreatPowerComesGreatResponsibility: She's cautious of the damage she can unintentionally cause to humans when fighting near a human population center.
553* TheXenophile: She's always been particularly awestruck and enticed by the Titans, especially Godzilla, and a passionate and driven Monarch operative in that respect.
554* YouAreBetterThanYouThinkYouAre: She's told as much twice, first by Godzilla and then by Rodan, when she's feeling disappointed in herself.
555* YouExclamation: She has one when she recognizes Jonah at the end of Chapter 2.
556* YouRemindMeOfX: Downplayed.
557** San's emotional breakdown reminds Vivienne of Madison's grief in the wake of San Francisco's destruction and Andrew's death, which prompts Vivienne to try comforting San much like she once comforted Madison.
558** Vivienne thinks to herself that Rodan's behaviour reminds her of a high school ex-boyfriend.
559* YouShouldHaveDiedInstead: She receives a variation. Ren briefly admits among other things that he wishes it was Serizawa instead of her who came BackFromTheDead.
560[[/folder]]
561----
562
563!!San
564Formerly Ghidorah's left head, notable for possessing a curiosity which his two brothers lacked and being the least malicious of the three. His mind survives inside the head that's ripped off by Godzilla. He's responsible for storing, reviving and transforming Vivienne's body inside his decapitated head before transferring his consciousness to the resulting hybrid’s second brain, becoming Vivienne's brother as part of Monster X. He functions as the secondary head.
565
566[[folder:Tropes A-M]]
567* AdaptationalSympathy: The film made San out to be goofier than Ghidorah's other two heads, and a doormat to the middle head who literally pushes him around and yells (roars) at him. In this fic, the expansion on San's and Ghidorah's characterization and backstory gives San even more sympathetic traits and redeeming qualities, and the abuse he suffers is ''not'' PlayedForLaughs in this version. He's been under chronic physical and verbal abuse from his brother heads whilst having literally nobody else for ''billions'' of years, which has in turn made him dependent, severely love-starved, and [[ItsAllMyFault prone to self-blame and self-loathing]]; [[spoiler:to say nothing of what he went through before all that with [[AbusivePrecursors the Makers]]]]. San also truly likes and cares for Vivienne, taking his new responsibility as her brother head to heart.
568* AdultAdoptee: Both {{exaggerated|Trope}} and {{downplayed|Trope}} [[spoiler:when Vivienne's mother Susan comes to consider him a son]]. Exaggerated in that San is a DraconicAbomination who is billions of years older [[spoiler:than Susan, and Susan herself is elderly by the time the adoption occurs]]; downplayed in that San, [[ImmortalImmaturity for all his chronological age]], is a little [[{{Manchild}} stunted]].
569* AffectionateNickname: After they become [[FireForgedFriends Fire-Forged Siblings]], Vivienne sometimes calls him "brother" instead of the name she gave him.
570* AfraidOfDoctors: [[https://hrodvitnon.tumblr.com/post/694435146019078144/ Word]] [[https://hrodvitnon.tumblr.com/post/711707754042114048/ of God]] has it that hospital horror would be one of the only things in humans' {{horror}} fiction works that would genuinely freak San out[[spoiler:, not least due to his bad memories of being on the receiving end of the Makers' experiments]].
571* AlternateSelf: Having come from the severed Ghidorah-head, he only has memories of Ghidorah's actions up to the head's decapitation, and he doesn't remember what his doppelgänger that regrew on Ghidorah's body did before it died with Ghidorah at Boston. Kind of like an outdated backup file copy.
572* AppropriatedAppellation: As of Chapter 8, he no longer considers Ghidorah's name to be his own, and he's taken the nickname Vivienne originally gave him as his new name. See the General folder for another example.
573* AscendedExtra: He's one of the two main protagonists alongside Vivienne, who gets a delightful deal of expansion and CharacterDevelopment, whereas in ''King of the Monsters'' he was 1/3 of the BigBad[='s=] MultipleHeadCase.
574* TheAtoner: He's become this after his and Vivienne's second {{Metamorphosis}}. [[https://hrodvitnon.tumblr.com/post/732727590928908288/ Word of God]] says that after San's HeelFaceTurn, he dreads something evil from Ghidorah's past showing up, because it would be the consequences of Ghidorah's actions when he was still part of it made manifest.
575* BecameTheirOwnAntithesis: Originally, he was the TokenGoodTeammate head of an OmnicidalManiac which went out of its way to kill humans and sought to destroy all life on Earth as we know it, he was considered the Youngest Brother, and he was abused by his siblings. After merging with Vivienne, San is now part of a hero-aligned Titan that defends the Earth and goes even more out of its way to minimize human casualties than even ''[[AllLovingHero Mothra]]'' would, but San also acts as said Titan's more unforgiving and pragmatic half; he's now the elder sibling according to himself (and he ''is'' originally billions of years older than Vivienne), and his new sibling is mutually-supportive to him.
576* BecauseYouWereNiceToMe: The fact Vivienne never abuses San the way his brothers did even before they become Fire-Forged further influences San's already-present loyalty and sense of kinship towards her.
577* BeingEvilSucks: For him, being part of Ghidorah was this. He was never as invested as his brothers were in being an OmnicidalManiac, his curious tendencies earned him abuse from his brothers, and he was starved of affection for ''eons''.
578* BewareTheNiceOnes: He's a real sweetheart towards Vivienne, and he's at least tolerant and curious towards humans if they haven't pissed him off, but God help you if you seriously hurt his sister.
579* BloodKnight: Though he isn't an OmnicidalManiac like his brothers, San does genuinely enjoy a real fight.
580* BrokenTears: San proves that a DraconicAbomination from the stars ''can'' shed {{tears of remorse}}, when [[HeelRealization the realization of just how much hurt he's unwittingly caused his sister]] hurls him into a [[HeroicBSOD BSoD]].
581* BroughtDownToBadass: {{Downplayed}}. After merging with Vivienne, he's no longer able to fly and the two are still learning to control their new "storm" powers, but they're still as powerful and capable as any other Titan. [[spoiler:He regains a bit of the power he lost in their final form]].
582* BrutalHonesty: {{Downplayed}}. He doesn't mean to be hurtful (depending on who he's speaking to), but he's blunt, honest, and doesn't leave out details regardless of how harsh the truth is. This is partly because San is new to the very concept of dishonesty, and once he wraps his head around it, he thinks it's a waste of brain-power (as noted by the author [[https://hrodvitnon.tumblr.com/post/637226140951625728/ here]]).
583* ByronicHero: He can actually be seen as this. He's sensitive to the point of being endearing, but he's the more HeroicNeutral of the duo, and he largely reserves humane caring and consideration for Vivienne (and perhaps also Mothra), while towards most others he's more tolerant and benign than anything else. There's also his Freudian ItsAllMyFault tendency, and he's strategically-competent at looking out for details during combat.
584* BystanderSyndrome: He has a neutral attitude to general humans in distress -- if said humans have given him neither reason to help them nor reason to want them punished, then San doesn't really see them as worth sticking his or Vivienne's necks out for either way. However, he'll go along with helping humans for his sister if it's what Vivienne wants.
585* CainAndAbel: The Abel to Ichi and Ni's Cain following his HeelFaceTurn.
586* CannotTellALie: It turns out that he literally lacks 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.
587* CatlikeDragons: {{Downplayed}}. San at times produces vocalizations comparable to purring, particularly as a reassuring or affectionate gesture towards Vivienne.
588* ComicallyMissingThePoint: {{Downplayed|Trope}}. Vivienne is horrified by his suggestion that they eat Jonah's mercenaries, saying she disapproves because "they're PEOPLE", so San amends his initial suggestion to: “''you don't have to [[ImAHumanitarian eat them]] maybe just kill them''”.
589* ComicBookFantasyCasting: [[https://hrodvitnon.tumblr.com/post/631248784044736512/ According to the author]], San's voice sounds like [[https://www.youtube.com/watch?v=A2p2XI5Mg50 Grigori]] from ''VideoGame/DragonsDogma'', particularly as his voice develops an accent with his CharacterDevelopment.
590* ConstantlyCurious: Compared to Ghidorah's other two heads, San is very curious and inquisitive, and he has a more [[{{Manchild}} childlike]] personality. [[spoiler:"Damnatio Memoriae" shows that he was like this even as an infant before [[WoobieDestroyerOfWorlds things went to hell]]]].
591* ContrastingSequelMainCharacter:
592** Godzilla is a marine monster native to Earth, he has a personality evocative of a GrumpyOldMan, his life bond with Mothra has romantic overtures, and he was GoodAllAlong in the [=MonsterVerse=] movies. San is an extraterrestrial entity who is humorously [[WhyDidItHaveToBeSnakes hydrophobic]], he has quirks indicative of a {{Manchild}}, he's PlatonicLifePartners with [[SiblingTeam his new sister Vivienne]], and his case of "good" is a HeelFaceTurn.
593** Now let's compare him to the human protagonists of ''Film/Godzilla2014'' and ''Film/GodzillaKingOfTheMonsters2019'' (Joe and Ford Brody and Mark Russell). Joe and Mark in particular have ExcessiveMourning as the focus of their characters and show signs of ItsAllAboutMe, Mark is known to lash out at and give his friends and loved ones a hard time for things that aren't their fault, and Ford is a big case of {{Mangst}}. San instead is the DraconicAbomination equivalent of a long-term abuse victim receiving recovery, he has ItsAllMyFault tendencies which approach GuiltComplex, San ''abhors'' humans "thundering in the ears" of their loved ones who've done nothing wrong, and he's very childlike.
594* CoolUncle: PlayedWith. [[spoiler:He's seen as Manda's adoptive uncle just as Vivienne is his adoptive mother]].
595* CounterAttack: He dodges a swipe of [=MaNi=]/Elder Brother's claws and takes the chance to crack Monster X's tail at [=MaNi=], cutting a deep gouge into the latter's face. See the General folder for another example.
596* CreepyGood: He's formerly one of ''[[DraconicAbomination Ghidorah]]'s'' three minds, and his voice sounds like [[https://www.youtube.com/watch?v=A2p2XI5Mg50 the dragon in these clips]] (InUniverse, San's voice notably sends shivers down the spines of human characters when they're first hearing it). Despite this, San's HeelFaceTurn is genuine, he's a sweetheart to his new sister who he means nothing but the best for, and he'll tolerate if not befriend you so long as you don't pose a threat and don't get on his bad side.
597* DamnYouMuscleMemory: He has a moment of this when Monster X is propelled into the air, at which point his memories from when he was part of Ghidorah and able to fly cause him to spread Monster X's arms out; forgetting that those arms aren't wings anymore.
598* DarkAndTroubledPast: He used to be one of [[{{Sadist}} Ghidorah]]'s three minds, and he was treated by the other two as the runt of the litter. Enough said.
599* DiscardAndDraw: As part of Monster X, he loses Ghidorah's BreathWeapon, WeatherManipulation and [[spoiler:flight (initially)]], but gains some new ShockAndAwe powers which enable SuperSpeed and InASingleBound instead.
600* DistressedDude: There are a few times where Vivienne's support saves him from his own psychological issues instilled by eons of abuse, plus [[spoiler:there's the time his head is almost killed permanently]].
601* DoNotCallMePaul: In Chapter 8, he spurns Ghidorah's name being used to refer to him, having disowned the monster he was once part of during his CharacterDevelopment.
602* EarAche: Ichi/Eldest Brother would frequently bite at his horns, and it's implied that in his species this is roughly equivalent to physical slapping.
603* EasilyForgiven: Mothra has no reservations towards him over his participation in Ghidorah's past atrocities -- which included acts of genocide and sadistic murder, nevermind the PlanetDestroyer crimes Ghidorah successfully committed before making Earth its next target -- whilst Godzilla as TheStoic refuses to hold onto old hard feelings. With Monarch and the Russells however, this trope is outright {{averted}}: they're at first very wary of San due to every awful thing they witnessed Ghidorah doing and attempting to do during ''King of the Monsters'', and it takes time for them to lower their reservations towards him. [[https://hrodvitnon.tumblr.com/post/689311522082668544/ Word of God]] also says that it'll take people in Monarch who haven't interacted with Monster X significantly longer to stop being distrustful of San.
604* EvilLaugh: In Ghidorah's one-shot origin story called "Damnatio Nemoriae", San cackles at the thought of unleashing Ghidorah's newfound power, [[spoiler:not least unleashing it against Ghidorah's much-despised tormentors]].
605* ExpendableClone: As a shed skin, he would be regarded by Ghidorah [[spoiler:and is regarded by all three of Ghidorah's regenerated and attached heads]] as nothing more than a shadow and a fake version of the Youngest Brother/Third.
606* ExpressiveHair: His horns bristle or flare out when he's angry or agitated, and they droop slightly when he's feeling defeated or sad, just like when he was part of Ghidorah.
607* ExtremeMeleeRevenge: When Vivienne hits her RageBreakingPoint, San practically ''obliterates'' the offender and Jonah's other Mooks, killing them in an excessive manner that prolongs their agony and doesn't leave much to bury.
608* EyeAwaken:
609** He has one which catches one of Jonah's mercs off-guard when he and Vivienne are first reborn from San's old head, in Chapter 2.
610** He has an unambiguously-heroic one in Chapter 16 when [[spoiler:Vivienne's lightning surges into and seemingly awakens his freshly-severed head]].
611** See the General folder for another example.
612* TheFogOfAges: In the present time, he can only vaguely recall his and his brothers' earliest memories and their origin story like he's recalling a dream, because it all happened so many ''billions'' of years ago.
613* {{Foil}}:
614** To Madison Russell. Whereas San got his wish for him and Vivienne to fully become family, Madison was deprived of the chance to have Vivienne as a legal guardian in the same instant. Madison is a teenage girl who's WiseBeyondHerYears, whereas San is an eons-old {{Manchild}}.
615** To Alan Jonah. Jonah losing his daughter caused his descent into villainy and then losing his surrogate son made him even worse, whilst San being separated from his brothers and then ''gaining'' a new sister in Vivienne leads him through a HeelFaceTurn. Whereas San always puts Vivienne's welfare before his own if it comes down to it, Jonah [[spoiler:indirectly caused Asher's death to save his own skin]]. San was effectively bound to the path of destruction he was led down in his backstory because of his brothers, whereas Jonah implicitly became the monster he is now due to isolating himself from all others during his start of darkness. Jonah is a leader, whereas San was a subordinate to his brothers.
616* FreudianExcuse: Though he's easily the TokenGoodTeammate to his brothers even when he's at his worst, San is still unnaturally vicious to enemies in his own right when he feels justifiably provoked, and these tendencies [[ReformedButNotTamed don't fully fade]] even after his HeelFaceTurn. This has a lot to do with Ghidorah's horrific backstory, [[spoiler:where San and his brothers were [[BeingTorturedIntoEvil brutally tortured]] and [[PlayingWithSyringes experimented on]] by the Makers for years, then were even further corrupted over eons by the [[TerribleTicking Old Noise]] driving them past the point of insanity until they learned to completely love killing and torturing things]].
617* GodzillaThreshold: One of Vivienne's berserker episodes gets so serious, San resorts to biting at her and then deliberately setting off a flashback of the moment Ichi/Eldest Brother ate her alive to make her stop lashing out. It's later implied his head resorts to biting her again to stop [[TerribleTicking the Old Noise]] from consuming her.
618* GotMeDoingIt: His mental voice gradually picks up a British-sounding accent from Vivienne over time.
619* GrandTheftMe: {{Downplayed}} -- he transfers his consciousness out of the decapitated Ghidorah head he came from and into the new second brain he's making grow on Vivienne's body before her rebirth, so that he becomes her "sibling" head. Also {{inverted}} in that San is largely doing this so that he can rear and care for Vivienne directly once she's reborn (becoming a "[[{{Dehumanization}} shed skin]]" in the process), rather than for his benefit and her detriment.
620* GrinOfAudacity: He has to restrain himself from grinning at the prospect of kicking [[spoiler:Ghidorah]]'s ass, and he fully has such a Grin at the prospect of fighting Rodan. See the General folder for more examples.
621* HappilyAdopted: [[spoiler:Besides eventually becoming accepted by Vivienne as her brother, he's eventually also fully adopted by Susan as her son]].
622* HeelFaceTurn: He effectively becomes HeroicNeutral after fusing to Vivienne. He later endures a HeelRealization, and additionally becomes TheAtoner as his CharacterDevelopment progresses.
623* HeelRealization: He has a brutal one in [[https://www.fanfiction.net/s/13357907/5 Chapter 5]], when he’s viewing Vivienne's memories and realizes ''why'' she's so miserable and doesn't trust him.
624* HeldGaze:
625** He and Godzilla have an interesting variation in Chapter 9. [[spoiler:Despite Godzilla and San's antagonistic history from when San was part of Ghidorah, neither are confrontational as Godzilla sternly tells San to be better than his brothers]].
626** In the non-canon HalloweenEpisode "Come Little Monster, I'll Take Thee Away", San, before bidding farewell to Ilene, Ling, Ziyi, Yong, Madison and Mark at the end, meets each of their gazes [[spoiler:and refers to them as friends]].
627** See the other folders for more examples.
628* HeroicBSOD:
629** When viewing Vivienne's memories, he has a pretty heart-wrenching kick-in-the-teeth HeelRealization about why Vivienne's been so wary of him and about how much Ghidorah's actions -- including San's specifically -- have tarnished her. It's short-lived as Vivienne brings him out of it.
630** He has a more minor one after he [[GodzillaThreshold resorts to deliberately reminding Vivienne of Ichi/Eldest Brother attacking her to snap her out]] of a PTSD-induced UnstoppableRage.
631* HopeIsScary: [[https://hrodvitnon.tumblr.com/post/689311522082668544/ Word of God]] notes that San at first found being severed from his psychotic brothers and lacking their direction to be scary, even if being free of their constant screaming and rage for the first time since Ghidorah's turn to evil was a relief.
632* HorrifyingTheHorror: According to [[https://hrodvitnon.tumblr.com/post/694435146019078144/ Word of God]], the only two elements of manmade horror fiction that would truly unnerve San instead of [[NightmareFetishist appealing to his ingrained sadistic instincts]] are: WebOriginal/TheBackrooms-style liminal space, and [[AfraidOfDoctors hospital horror]].
633* HumanityIsInfectious: Vivienne says this almost word-for-word when referring to San's HeelFaceTurn in Chapter 9. Indeed, Vivienne acts as San's MoralityPet, fueling his CharacterDevelopment, and she also sates his curiosity towards humans.
634* IAmNotAGun: Ghidorah's {{backstory}} essentially makes San this following his HeelFaceTurn.
635* IJustWantToBeLoved: 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.
636* IllKillYou: He angrily and repeatedly declares this after he and Vivienne (mainly Vivienne) is horrifically injured by a chlorine gas experiment.
637* ImmortalImmaturity: A heroic/positive example. For a former part of a supposedly-immortal, TimeAbyss-old alien monster, San can be quite childlike. Probably {{justified}} by a [[DarkAndTroubledPast stunted psychological development]].
638* ImmortalsFearDeath: He used to never worry about dying due to Ghidorah's ability to always [[FromASingleCell regenerate]], but in Chapter 5, he's terrified by the prospect he might die permanently due to his transformation into Monster X. [[spoiler:[[https://www.tumblr.com/hrodvitnon/699677927317569536/ Word of God]] confirms that he's still somewhat thanatophobic, although it appears to be tempered at the fic's end]].
639* InformedFlaw: His tendency seen in ''King of the Monsters'' to be distracted and slow on the uptake (which is referenced in this fic) becomes this. As part of Monster X, he's actually quite competent and quick-on-the-draw. Possibly {{justified}} by him caring for Vivienne giving him extra motivation to do a good job that he didn't have with his brothers.
640* InSeriesNickname: He was given his name by Vivienne while she was monitoring Ghidorah in Antarctica -- he initially 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]]. It's indicated that Ichi and Ni would have called him "Youngest Brother" when he was still attached to them, [[spoiler:and it's what they call San's regrown AlternateSelf]].
641* IntriguedByHumanity: He's genuinely curious about humans overall, and apparently he's always been this way [[spoiler:even when encountering other "little ones" on other worlds before Earth]]; unlike his brothers.
642* 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 and [[MoralMyopia MaNi/Elder Brother]]]] notably consider San an "it" due to Ghidorah's {{Dehumanization}} of its heads' "shed skins".
643* ItsAllMyFault: He has a serious tendency to mentally kick himself senseless when something goes seriously wrong and he thinks it's his fault. It's nigh on GuiltComplex levels, and it's rooted in [[DarkAndTroubledPast how his brothers treated him]].
644* KidnappedForExperimentation: [[spoiler:In Ghidorah's backstory, San and his brothers were originally living in the wild when they were juveniles, before they were captured by the Makers to be [[PlayingWithSyringes experimented on]]]].
645* KilledMidSentence: ''Narrowly'' {{subverted}} [[spoiler:when his head is ripped off of Vivienne and almost devoured, in Chapter 16]].
646* KnightTemplarBigBrother: He's willing to kill if someone's crossed his sister, and he takes his [[BigBrotherMentor Big]] [[BigBrotherInstinct Brother]] responsibility to Vivienne seriously. Vivienne at first abhors the former, but the duo become more cooperative with each other over time.
647* LifeEnergy: [[https://hrodvitnon.tumblr.com/post/689317106053955584/ Word of God]] notes that his original severed head needs to conserve its internal backup supply of power and absorb power from sources it comes into contact with, in order to remain animate.
648* {{Lobotomy}}: Horrifically, the ''Empty Fullness'' one-shot "Damnatio Memoriae" reveals he was effectively subjected to one in the distant past billions of years ago. [[spoiler:Specifically, it's revealed that the Makers cut directly into his brain to permanently hardwire it to notice little details that Ghidorah's other two heads might miss, so that he would act as Ghidorah's sentry head. A temporary side-effect was that San's communication became [[SpeechImpediment distinctly slowed and slurred]] after the surgery, although he fully recovered it after a time]].
649* LockedOutOfTheLoop: He at first isn't aware of the main Ghidorah's death after his decapitation, until Vivienne passes the news on to him.
650* LosingYourHead: His original head severed from Ghidorah retains his mind and some degree of consciousness, as long as it [[https://hrodvitnon.tumblr.com/post/689317106053955584/ conserves/recharges its power]]. {{Downplayed}} in that while San's mind is aware inside the head, on the outside the head remains (''seemingly/mostly'') immobile. [[spoiler:Then in Chapter 16, this trope gets PlayedStraight when San's head is ripped off of Vivienne by [=MaNi=]/Elder Brother]].
651* LoveRedeems: Vivienne, as his MoralityPet, influences his CharacterDevelopment into a more benign and non-malicious being, and San admits that he feels an emotional kinship with her that he didn't get from his [[BigBrotherBully brothers]].
652* MagicalDefibrillator: It's {{implied}} he gets a ShockAndAwe variation, when [[spoiler:exposure to Vivienne's lightning makes his head spring back to life, in Chapter 16]]. {{Justified}}, given ''[[DraconicAbomination what]]'' [[DraconicAbomination San is]].
653* {{Manchild}}: ZigZagged. He seems to have a developmentally stunted personality and can often be very childlike -- almost like an abused puppy. But he also has a much more serious, intelligent and pragmatic side when it's needed.
654* MasterOfYourDomain: His original decapitated head is able to both keep Vivienne alive in a coma inside itself and metamorphose her into an ArtificialHybrid when San wills it, while also forming a second head on the transformed Vivienne which San's mind can transfer into.
655* MeaningfulName: {{Subverted}}. Like in [=MonsterVerse=] canon, his name being the Japanese number three fits with his third-most position on the bottom of Ghidorah's heads' pecking order; and furthermore, this fic confirms he's apparently the youngest of the original three brothers [[spoiler:whom Ghidorah was made from]]. [[https://www.tumblr.com/hrodvitnon/699677927317569536/ Word of God]] suggests that when Vivienne gave San his name, she was influenced by San and his brothers telepathically whispering to her in her dreams. See the above folders for more examples.
656* MeetTheInLaws: PlayedWith. As [[https://hrodvitnon.tumblr.com/post/711707754042114048/ noted]] by the author and hinted at in "Ain't That a Kick in the Head", in time he might want to make a good impression on Dr. Ling, Vivienne's [[AmicableExes amicable ex]], because of her past relationship with his sister.
657* MinionWithAnFInEvil / TokenGoodTeammate: His brothers certainly view him as the former trope. Even before his HeelRealization, he's less malicious than Ichi/Eldest Brother and Ni/Elder Brother, he's genuinely inquisitive, and he's not really invested in his brothers' [[OmnicidalManiac Omnicidal Mania]] after being separated from them. However, he remains brutal when fighting or when provoked too far, and he's a competent sentry head.
658* MirrorCharacter:
659** Once San's backstory is revealed, it turns out that both San and Madison Russell experienced [[spoiler:a tragic trauma in their past alongside their respective families]], which left them in the care of an elder family-member who had become genocidal and acted emotionally abusive towards them following said event. For both Maddie and San, Vivienne acts as a more loving, healthy familial substitute to said abusive elder.
660** It turns out San and Alan Jonah were both led down the paths of omnicidal destruction in their respective backstories due to [[spoiler:a traumatic tragedy befalling them and their immediate family]]. Interestingly, fear of dying is also something that both characters have in common.
661* MistreatmentInducedBetrayal: Towards Ghidorah. The fact Vivienne never treats him abusively like his brothers did influences San's HeelFaceTurn as his CharacterDevelopment progresses.
662* MyGodWhatHaveIDone:
663** ''Abraxas'': Upon his HeelRealization, he comes to deeply regret what he and his brothers have done to Vivienne. He apparently still carries remorse after Vivienne has forgiven him.
664** ''Abraxas: Empty Fullness'' "[[https://archiveofourown.org/works/46831738/chapters/122322187 Damnatio Memoriae]]": {{Implied}} when Ghidorah is in the process of wiping out all visible life on a sapient world for the first time. The left head's dialogue consists of him musing how there'll be no more of anything for the lifeforms they're exterminating, and at the end of it; he passes comment on how there's "so much dust" everywhere and how the planet's natives were "crying and screaming" as they died, before his observations on their destruction take on a more cynical and nihilistic tone.
665* MyGreatestFailure: He at times shoots glares or gets angry when someone brings up his past as part of Ghidorah against him, but he seems to regret the psychological harm he's caused Vivienne most of all.
666[[/folder]]
667
668[[folder:Tropes N-Y]]
669* NearDeathExperience: {{Implied}}. Besides the one he shares with Vivienne, in Chapter 16, [[spoiler:it's suggested he has one after his head is ripped off and almost SwallowedWhole before his head gets an electrical jolt]].
670* NightmareFetishist: [[https://hrodvitnon.tumblr.com/post/694435146019078144/ Word]] [[https://hrodvitnon.tumblr.com/post/704531515544092672/ of God]] comments, and the non-canon [[HalloweenEpisode "Come Little Monster, I'll Take Thee Away"]] shows; that San would have a genuine appreciation for mankind's creativity in horror movies if he saw them, particularly when it comes to inducing feelings of fear and anxiety and when it comes to the murder scenes. He would ''also'' be interested by the more morbid and less-discussed aspects of Christmas lore and history, like {{Krampus}}, if he were introduced to the holiday.
671* TheNoseKnows: "Damnatio Memoriae" depicts San [[spoiler:as a Dorat]] using his sense of smell to track the Makers' whereabouts before he sees them. See the General folder for more information.
672* TheNothingAfterDeath: He apparently saw this between Vivienne's first death and her revival inside Ghidorah when viewing her memories (suggesting she had a CessationOfExistence), and he becomes terrified of entering the Nothing if he and Vivienne die permanently. [[spoiler:He gets past it in "Sermones ad Mortuos"]].
673* NotQuiteDead: After his original head is ripped off of Ghidorah by Godzilla, it remains partially alive, retaining San's mind and pre-decapitation memories.
674* ObliviouslyEvil: ZigZagged and {{downplayed}}. He's under no illusions about the cruelties his brothers are capable of nor about how he relished in carnage himself to a degree when he was part of Ghidorah, but he's genuinely confused as to why Vivienne doesn't immediately embrace him as her new brother, and why she would consider her transformation into a bigger and stronger creature [[FateWorseThanDeath crueller than death]]. Ultimately {{subverted}} when seeing Vivienne's memories from her perspective gives San a HeelRealization about what he did to her.
675* TheOlderImmortal: {{Lampshaded}} in Chapter 18. As a former part of Ghidorah (who is billions of years old), San is believed to be older in age than all the Earth-native Titans, who are presumed to be hundreds of millions of years old at the most.
676* OneSteveLimit: {{Lampshaded}} when Vivienne makes a joke about San Lin from ''Film/KongSkullIsland'' and San reacts with surprise.
677* TheOneThingIDontHateAboutYou: Sort of. The only aspect of being part of Ghidorah that he remembers with fondness is the feeling of being able to fly.
678* PaintItBlack: {{Inverted}}. Following his HeelFaceTurn, he fully trades his original gold color for gray flesh and bone during Monster X's second {{Metamorphosis}}.
679* ParentalAbandonment: San has never had parents before, and though he's not at all bothered by his biological sire having no role in his and his brothers' maturation, as his CharacterDevelopment progresses he comes to crave the experience of having a mother figure like his sister had in her upbringing.
680* PowerEchoes: His voice is described as sounding echoic when he communicates with Vivienne telepathically, and his ComicBookFantasyCasting voice probably helps.
681* ThePromise: He promises Vivienne in Chapter 3 that the two of them will escape their imprisonment and fix their MergingMistake – he emphatically repeats it after Vivienne bitterly warns him not to make promises one doesn't know they can keep. [[spoiler:Eventually, Viv and San escape together, and although it's Mothra rather than San who fixes their merging mistake, the latter half of San's promise is otherwise fulfilled]].
682* PsychicBlockDefense: He attempts performing this multiple times to keep [[spoiler:Ghidorah's voices]] out of his and Vivienne's heads.
683* PsychopathicManchild: {{Downplayed}} after he fuses with Vivienne and undergoes CharacterDevelopment, but besides his {{Manchild}} quirks, he's more nonchalant than her about attacking and killing when provoked. Before fusing with her, San seemed to regard Vivienne the way a child regards their favorite doll or teddy-bear.
684* QuizzicalTilt: Being the inquisitive Good Boi that he is, he exhibits this a few times over the fic when he's curious or just confused about something.
685* TheReasonYouSuckSpeech:
686** He angrily chews out [[spoiler:Susan Graham]] for reacting as she did to Monster X and [[spoiler:unwittingly hurting Vivienne]].
687--->"''YOU WERE THE REASON SHE [[spoiler:WANTED OUT OF THE CAGE. [...] ALWAYS THINKING OF YOU, IN WAKING AND DREAMING]]. SHE WAS AFRAID YOU [[spoiler:MIGHT BE DEAD, AFRAID YOU MIGHT LIVE]], AFRAID OF WHAT YOU MIGHT SAY. SHE DID NOTHING WRONG, BUT YOU THUNDER IN HER EARS! YOU SAY SHE IS DEAD! YOU DON'T LISTEN! YOU HURT AND FRIGHTEN HER!''"[[note]]Yes, San was [[BewareTheNiceOnes screaming in capitals]][[/note]]
688** San himself gets one from [[spoiler:Ghidorah and Ni/Elder Brother's Many-construct]] in Chapter 16:
689--->'''Ichi''': '''[[ItIsDehumanizing IT]] THINKS IT CAN PROTECT [Vivienne]? IT COULD NOT EVEN CHANGE HER INTO OUR SHAPE!'''\
690'''San-2''': even when you do something right you ruin it\
691'''Ichi''': '''IT CAUSED HER SUFFERING! IT TOOK THE QUEEN GNAT TO FIX THAT MISTAKE!'''\
692'''San-2:''' so much of her is broken because of your mistake\
693'''Ni''': IT CANNOT EVEN TEACH HER TO CONTROL HER POWER.\
694'''San-2''': we would have shown her the most wondrous things\
695'''Ichi''': '''IF IT CARED SO MUCH, IT WOULD HAVE TAUGHT HER BETTER, NO?'''
696* ReflectiveEyes: An InUniverse case in Chapter 5, when Vivienne views her transformed face for the first time via the reflection in San's eyes. See Vivienne's folder for another example.
697* ReformedButNotTamed: He was always the least malicious of Ghidorah's three heads, but even after his HeelFaceTurn, he's still a BloodKnight, and he can be as violent as Ghidorah when ItsPersonal with his enemies.
698* ReformedButRejected: He at first receives this treatment from Monarch, and especially from Madison and Mark, because they're understandably wary of a former head of Ghidorah. Their reservations lower with time when they realize San's HeelFaceTurn and care for Vivienne are genuine.
699* RemovedAchillesHeel: When he was part of Ghidorah, being submerged in waters deep enough for Ghidorah's size was his and his brothers' LogicalWeakness. Monster X's different body structure coupled with Vivienne knowing how to swim means this is no longer a handicap for him.
700* TheRuntAtTheEnd: It's explicitly confirmed in this fic that he's the Youngest Brother among Ghidorah's three heads according to himself and his brothers. He's also the only one of the three who has any real capacity for redemption -- thanks to Vivienne's influence and him being cut off from Ghidorah, San ends up fulfiling that potential.
701* SayMyName: He does this a couple times, overlapping with YouCalledMeXItMustBeSerious, when he's distressed and calling out to his sister in fear and need of her.
702* SensitiveGuyAndManlyMan: He's the Sensitive Guy to Rodan's Manly Man: an inquisitive, curiosity-driven {{Manchild}} who is as sweet as a giant puppy towards his sister, but when ferocity is needed or when someone he isn't close to has crossed him, he can easily remind everyone that he used to be one of [[AxCrazy Ghidorah]]'s heads.
703* SeriesContinuityError: San thinks in the first couple chapters that he's never been a singular entity separated from his brothers before. Chapter 10 establishes [[spoiler:San, Ni and Ichi used to be three separate creatures who ''became'' Ghidorah]]. {{Justified}}, as these memories of San's are so distant, he barely recalls them and he seemingly isn't even sure anymore that they're real.
704* SickeningCrunch: This notably occurs when [[spoiler:[=MaNi=]/Elder Brother rips his head off]].
705* SignificantNameShift: He goes from calling Ghidorah's other two heads "Elder Brother" and "Eldest Brother" respectively to mainly simply referring to them as the "right head" and "middle head" respectively, symbolizing his disownment of them as his post-HeelFaceTurn CharacterDevelopment progresses.
706* SilenceOfSadness: He's silent around Vivienne out of shame and self-deprecation, after he resorted to pressing down on Vivienne's Ghidorah-related TraumaButton to snap her out of a psychotic fit. See the other folders for more examples.
707* SleepDeprivation:
708** During his and Vivienne's early days imprisoned, he willingly foregoes sleep so he can keep watch over his sister while she tries to rest.
709** [[spoiler:Ghidorah's StartOfDarkness story in "Damnatio Memoriae" reveals that sleep deprivation was among the multiple agonies that San and his brothers endured during their captivity by the Makers, due to [[TerribleTicking the Old Noise]] screaming in their heads and then later due to [[UsedToBeASweetKid the other two heads]] being [[PlaguedByNightmares plagued by trauma-induced nightmares]]]].
710* SnakesAreSinister: {{Averted}}. He's essentially an alien hydra-head by origin, and he retains his old head's serpentine qualities when Monster X metamorphoses into its second form after San's HeelFaceTurn.
711* 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.
712* SpeechImpediment:
713** Whenever he communicates with humans via his electronic voice projection, his voice comes through speaking in a stilted, halting manner with notable breaks. The effect disappears as the fic goes on, implicitly because he's getting used to communicating this way.
714** In the StartOfDarkness-chronicling prequel "Damnatio Memoriae", his speech is even more perpetually slow and slurred for a temporary time, [[spoiler:immediately after [[{{Lobotomy}} his brain was cut open and rewired]] to make him act as Ghidorah's detail-keen sentry head]].
715** See the General folder for another example.
716* SuperEmpowering: He transforms Vivienne, a human, into part of a Ghidorah hybrid Titan; by regenerating her while deliberately feeding his own enzymes into her when she's inside his severed head. Granting their shared body Ghidorah's HealingFactor and bio-electricity, and {{Kaiju}} SuperToughness.
717* SwallowedWhole: [[spoiler:''Narrowly'' {{subverted}} in Chapter 16 when [=MaNi=]/Elder Brother rips his head off and attempts to devour it. Vivienne violently rescues her brother's head]].
718* TearsOfJoy: {{Downplayed}}. His eyes turn watery a few times when he's truly happy.
719* TearsOfRemorse: Sheds these after his HeelRealization.
720* TerseTalker: Downplayed, but his dialogue is sometimes written this way, particularly when he's angry or distressed.
721* ThickerThanWater: Both played basically and very much averted. He considers himself and Vivienne blood siblings as well as emotional/adoptive siblings following their merger, and he is nothing short of loyal and caring towards her. Meanwhile, San disowns Ichi and Ni as his brothers as his CharacterDevelopment progresses (not least because they are "Biggest Cunts" and all-round evil). It's also telling that San and his brothers had [[spoiler:many biological sisters who died in infancy]], but San considers Vivienne the first true sister he's ever had.
722* ThirdPersonPerson: A slight variation. He initially refers to himself exclusively as "this one" or otherwise excludes first-person pronouns from his dialogue, but this changes as he gains a better sense of self-worth. The author went into further detail about why he does it [[https://hrodvitnon.tumblr.com/post/661353979839741952/ here]].
723* 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. See the General folder for another example.
724* VillainRespect:
725** {{Downplayed}} regarding Godzilla. According to [[https://hrodvitnon.tumblr.com/post/689311522082668544/ Word of God]], San understands Godzilla's pragmatism regarding how Godzilla systematically caused San's decapitation from Ghidorah, and it sounds like San even slightly admires what this says about Godzilla's combative prowess.
726** PlayedWith regarding [[spoiler:Thor's son]]. Though it's only after San's HeelFaceTurn that his thoughts on it are explored, he observes that [[spoiler:Thor's son]] died honorably when he fought Ghidorah to the death and was DefiantToTheEnd.
727* WhatIsThisFeeling: Downplayed when he has his HeelRealization in Chapter 5. It's clear that he's unfamiliar and unused to the painful emotions that he's experiencing, but he still knows exactly ''why'' he's feeling them.
728* WhenHeSmiles: Several characters have observed that when San smiles in genuine happiness without any violent intent compared to his SlasherSmile, it's quite disarming.
729* WhiteSheep: He becomes this to his brothers and AlternateSelf, being determined to be better than Ghidorah.
730* WhyDidItHaveToBeSnakes: He hates being in deep waters, since it was his LogicalWeakness when he was part of Ghidorah.
731* TheWorldIsJustAwesome: Over the course of his CharacterDevelopment, he's developed an appreciation for the world's beauty and wonders.
732* YouCalledMeXItMustBeSerious: It's usually a sign that things are frighteningly serious when he calls Vivienne by her name instead of calling her "sister".
733* YoungestChildWins: Ghidorah's left head is explicitly [[TheRuntAtTheEnd the "Youngest Brother", or "the Third" of the Three]]. He's also the only one of them who has any redeeming qualities that have survived beyond Ghidorah's past, and this enables San to break free of Ghidorah's evil for good via Vivienne's influence.
734* YouRemindMeOfX: The downplayed form. [[https://hrodvitnon.tumblr.com/post/673233908668694529/ Word of God]] notes that San was endeared to Vivienne from the beginning partly because she reminded him of a smaller, less powerful version of himself. [[spoiler:It's also confirmed that a huge factor in San's hatred of Jonah is that the latter's actions bring back San's distant memories of when he and his brothers were [[BeingTorturedMakesYouEvil being tortured into evil]]]].
