!!"Holy Mother" Christella Revi / "Suisho Hinomiya"
[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/imageedit_20_2398360375.jpg]]
->'''Voiced by:''' Mako Hyodo (Japanese), Mary Alice [=McGuire=] (English, OVA), Creator/MonicaRial (English, ''Decode'')
A rogue alien scientist secluded in Aokigahara with a cult devoted to her worship. A woman shrouded in mystery, she is wanted by the Federation as an Altan criminal supposedly behind the deaths of millions, but there is more to her than meets the eye. In truth, Christella was once a prodigious Altan scholar that rose to prominence despite the intense discrimination against her people. Under mysterious circumstances, she vanished and eventually reappeared as a terrorist opposing the Federation.
----
* AdaptationalGenderIdentity: [[spoiler:In the remake manga, Birdy initially assumes that Revi is male based on Federation data, only to be shocked to learn Revi is female -- and then learn that Revi ''was'' born male and her current gender is because of a failed attempt to save Tunica Cephon's life by merging her with Revi, much like Birdy was able to do with Tsutomu. Granted, the original manga and OVA, like ''Decode'' after them, never finished their stories, but given Birdy not only doesn't express confusion about Revi's gender, but also refers to Revi with female pronouns from the start and even recognizes Revi on the spot the first time she sees her on Earth in those, it does suggest that those incarnations of Revi were born female.]]
* AffablyEvil: Possesses an impeccably graceful and polite demeanor despite being a bioterrorist.
* AmbiguouslyEvil: Her motivations are reasonable despite her destructive means of obtaining liberty and justice for her people. She is viewed as a legendary figure among the oppressed Altan people, and Gomez himself admits in the OVA he cannot tell if Christella Revi is an angel or a devil in disguise.
* AMotherToHerMen: [[spoiler: Revi was willing to sacrifice her life twice to Nechla if it meant she would stop killing her workers.]]
* AntiVillain: Her ultimate goal is to end the brutal discrimination and abuse of Altans by the Federation, [[spoiler: and to free the entire galaxy from an evil AncientConspiracy.]]
* ArmorPiercingQuestion: After telling her whole story and motivations to Birdy, she asks if arresting her ''now'' will ease her visibly troubled conscience. Stunned, Birdy is unable to answer but is still determined to eventually take Revi to a court of law.
* TheAtoner: By the end of the manga, [[spoiler: she gracefully takes a life's sentence in prison along with Gomez for all the atrocities they were complicit in to achieve their goals.]]
* BathingBeauty: In her first scene in the third part of the the OVA, the audience is introduced to Revi as she's swimming in a pool.
* BenevolentBoss: She treats her Marionettes and Gomez as if they are equals, often telling them to drop the formalities and talk to her casually.
* BigBad: She takes over as the primary antagonist for the second half of the remake manga, ''Evolution.''
* CruelToBeKind: [[spoiler: Not wanting Towa to grieve or even follow him to his death, Revi callously tells him to forget all about the mother he knew before departing to confront the Sanctum Sanctorum.]]
* CurtainsMatchTheWindow: Hair and eyes are the same color.
* CynicismCatalyst: [[spoiler: The slaughter of Maxwell and his entire monastery shook Revi to the core, beginning her descent into terrorism.]]
* DeathGlare: She is capable of giving a piercing gaze that even strikes fear into Birdy Cephon.
* DeathSeeker: [[spoiler: What Gomez speculates is that Revi plans on confronting the Sanctum Sanctorum with dying fully on mind. He won't see to that, reminding her she must pay for her vast amount of crimes with him in court.]]
* DefectorFromDecadence: Was originally a biologist working for the Federation until she rebelled.
* DissonantSerenity: She never loses his dispassionate demeanor, even staring death in the face. However, when she is truly angry, she is capable of giving a bone-chilling DeathGlare.
* EvenEvilHasStandards: In ''Decode 02,'' Gomez tells Moss that Revi has rejected her desire to join her, citing the military's hazardous, rogue actions with the Ryunka is in direct violation of her established ethics.
* EvenEvilHasLovedOnes: She truly loves her child Towa and shields him from the horrors of her actual work.
* EvilutionaryBiologist: A prodigy in biology and genetic research. She has since turned her talents over to engaging in terrorism, albeit for well-intentioned reasons.
* FreudianExcuseIsNoExcuse: Birdy lays this out on Revi when they finally have a heart-to-heart talk, saying that no matter how much she suffered, it gives her '''no right whatsoever''' to indiscriminately ruin the lives of innocent people like herself, angrily telling Revi that she took her mother from her in the Central Tower attacks.
* GreaterScopeVillain: In most iterations of the story, Revi is this due to all but one of them being cut short. She tugs the strings of various antagonists, but her motives are never thoroughly explained. She also serves as this for the first half of the remake manga, being responsible for financing Hikawa's work but otherwise doing little to nothing on-screen.
* HeWhoFightsMonsters: Invoked, literally. [[spoiler: Birdy states that, despite her FreudianExcuse, her acts of terror across multiple star systems have made Revi a metaphorical monster. She responds by saying she's aware of this, but one must "become a monster to defeat monsters."]]
* TheHeretic: [[spoiler: Her official designation by the department of worship, and by extension, the Sanctum Sanctorum is literally this. Nechla also declares Birdy a heretic supporter for defending her.]]
* HeWhoMustNotBeNamed: Due to her actions, she is vilified in Federation-aligned nations. The mere mention of her name is considered taboo.
* HumanityIsSpecial: [[spoiler: When discussing with Megius about the fate of the galaxy at large in the epilogue, Revi says this about humanity, stating she believes in the potential of children like Towa, Chigira, and Sayaka to guide humanity from their past mistakes.]]
* LivingLegend: Among Altans, she is viewed as a legendary figure that rose to prominence despite being a third-rate citizen. Even now among the oppressed populace, she is viewed as a hero fighting for their sake.
* LovedByAll: [[spoiler:During her brief term in the Ministry of Science, Revi was viewed as a paragon among the Altan people.]]
* AMillionIsAStatistic: Tells Birdy [[spoiler: that she is willing to use multiple '''billions''' of lives as a means to an end if she achieves her goals of freeing the galaxy from the tyranny of the Sanctum Sanctorum.]]
* MoralEventHorizon: In-universe. [[spoiler: Revi vaguely tells Towa what she [[BreedingSlave intends to do]] with Birdy is crossing a point of no return and entrusts the child to lead her cult as a better person.]]
* MsFanservice: A tame example of this, but Revi is often seen in scantily clad robes or in the middle of dressing up as her devotees talk to her behind closed doors.
* NavelDeepNeckline: Under the guise of a cult leader, Revi often wears her robes with the front completely open.
* NervesOfSteel: She never loses her cool, even when facing likely death.
* NonActionBigBad: In a WorldOfBadass like this, Revi distinctively has no fighting ability whatsoever.
* SamusIsAGirl: Not a strict use of the trope as Revi isn't an ActionGirl, but in the remake manga and Decode no one, not even Birdy, outside a few people know that she is a woman. Averted in the original manga and OVA where it's pretty well-known what gender Revi is. [[spoiler:In the remade manga, Tsutomu and his family even end up staying at Revi's house for a little without him or Birdy realizing it, though this is likely due to the before-mentioned fact that Revi was born male.]]
* TheSociopath: Subverted. Despite all the implications of being a discompassionate extremist who would sacrifice anything and anyone to achieve her goals, it's shown in ''Evolution'' that Revi has the capacity for genuine empathy and even remorse, being wracked with both emotions when [[spoiler: facing down a mutated Nechla.]]
* TeethClenchedTeamwork: A one-sided example. [[spoiler: Revi eventually forms an alliance with Birdy, and by extension, Megius, to uncover the conspiracy surrounding the Sanctum Sanctorum. Birdy makes it crystal clear she is not happy with the situation, however, but Revi remains polite and cooperative.]]
* TenderTears: [[spoiler: Sheds tears when the secrets behind Maxwell's research is steadily unraveled.]]
* ThatManIsDead: [[spoiler: Casts aside his identity as Suisho Hinomiya towards the end of the manga, and coldly tells his son to simply forget that person was ever real and move on with his life.]]
* TranquilFury: When she gets angry, it is almost always this.
* TrulySingleParent: It's unknown who Towa's father is.
* UnlimitedWardrobe: She almost always wears a new outfit for every occasion.
* WellIntentionedExtremist: ''Very'' extreme, but very well-intentioned; Revi fights for the freedom of all those that suffer under the machinations of a truly evil conspiracy.
* WoobieDestroyerOfWorlds: When it's all put together, Revi is this in spades.
* YouCouldHaveUsedYourPowersForGood: [[spoiler: Birdy claims Revi could have done so much more good as the head of the Ministry of Science. She agrees but explains how she was forced to resign, meaning she didn't exactly have a winning hand.]]
!!Her true identity
[[caption-width-right:300:[[labelnote: SPOILER]]https://static.tvtropes.org/pmwiki/pub/images/revi_face.PNG]][[/labelnote]]
After spending most continuities as an enigmatic figure, late into ''Evolution'', Revi's backstory is fully explored [[spoiler: as she begins a tenuous alliance with a fugitive Birdy against the Federation. Born male, Christella Revi was a normal Altan kid who was forced to attend a private boarding school dedicated to the department of worship due to his potential. Although the life of a clergyman wasn't what Revi desired, he befriended Altans Maxwell Peridan and Tunica Cephon during his days at the school. Tunica, an Ixorian bound to the church [[NoSocialSkills had no knowledge of the outside world]] or how normal people were. Revi quickly became close friends with Tunica, regularly sneaking her out of the school to play. Tragically, Revi and Tunica were caught in the middle of an Altan terrorist bombing, and the latter perished due to being unusually frail for an Ixorian. Blaming Revi for her fate, the Cephon science department was pressured by the church to bring Tunica back by fusing her consciousness into a comatose Revi. The operation failed, with Revi waking up to be the only mind in his body. However, Revi gained all of Tunica's memories and [[PhotographicMemory powers]], becoming hyper-intelligent and rising to become the head of the Ministry of Science despite being an Altan. Due to the faulty fusion process, Revi's body sporadically turned female, which he concealed from others. After seeing through Tunica's [[RapeAsBackStory darkest memories]] and files of [[TykeBomb her creation]], Revi began an investigation into the department of worship and the sanctum they serve. Revi lost his position in the Ministry of Science before his first term even ended, being falsely accused of leaking high-grade weapons to Altan terrorists and forced to resign. After Maxwell was excommunicated and slaughtered in his own uprising, Revi lost faith in diplomacy and became a terrorist. With a female form, Revi was able to elude the Federation and started a base of operation on Earth. Forming an alliance with US and Japanese governments with Hikawa as her sponsor, Revi began to prepare for a final battle against the Federation to [[WellIntentionedExtremist liberate the oppressed from the Sanctum Sanctorum]] [[HeWhoFightsMonsters no matter the cost.]]]]

[[folder:Gomez]]
!!Georg Gomez
[[quoteright:264:https://static.tvtropes.org/pmwiki/pub/images/imageedit_32_3915930975.png]]
->'''Voiced by:''' Creator/AkioOtsuka (Japanese, OVA), Cory Carthew (English, OVA), Creator/UnshoIshizuka (Japanese, ''Decode''), Creator/NewtonPittman (English, ''Decode'')
An Altan criminal hiding on Earth under an alias. While publicly an unassuming owner of a small importing company, Gomez is an intermediate for illegal galactic smuggling and the right-hand man of Christella Revi. A highly enigmatic figure, his kind heart and preference for diplomacy betray his allegiances.
----
* AdaptationalJerkass: While he is certainly not more villainous, as a result of his screentime [[DemotedToExtra being brutally cut down,]] just about all of the humanizing elements to Gomez's character from the remake manga are notably not present in ''Decode.'' As a result, he comes off as notably more cold, even if his heart is still in the right place.
* AdvertisedExtra: In ''Decode'', Gomez has a notable appearance in the show's opening, but he is ''massively'' [[DemotedToExtra downgraded]] in importance to the show itself from other continuities.
* AscendedExtra: While Gomez is only implied to be of importance in most incarnations of the story, he becomes a leading supporting character in the remake manga.
* AlliterativeName: '''G'''eorg '''G'''omez
* AffablyEvil: Despite his shady allegiances, Gomez is a compassionate and impersonal man who exudes next to no malice. [[spoiler: It's no surprise he actually isn't evil at all.]]
* AmbiguouslyEvil: Whether Gomez is evil ''at all'' is a plot point. Despite overseeing Christella Revi's operations, he is ''never'' seen doing anything evil of his own volition. Birdy constantly suspects him as a villain due to his role in murdering Geega and Bacillus, but he points out the only reason he did so was that his family's safety was jeopardized by their actions. Furthermore, after witnessing the depths of Hikawa's depravity, Gomez even takes cautious strides to undermine him, making him one of his greatest enemies. [[spoiler: In ''Evolution'', it's revealed he's a relatively good guy all along.]]
* AntiVillain: In an honest and heartfelt conversation with Birdy, he explains he only fights for his perceived justice just as she does for her own. This implies he has the utmost faith in Christella Revi's ideals being noble despite her means to achieve them. [[spoiler: As it's later revealed, while he does indeed have undying faith in Revi's ideals, he is not entirely approving of her brutal methods and observing her as a person to the end to see if she is ultimately just a criminal.]]
* TheAtoner: [[spoiler: He's always planned to turn himself in once he helps achieve Revi's goals. By the end of the manga, they both face a lifetime sentence in prison for all their atrocities. Gomez entrusts Chigira with the safety of his family, as he intends to spill the beans on everyone involved with Revi's grand conspiracy.]]
* BarbarianLongHair: Before arriving on Earth, he had long, unkempt flowing hair.
* BeardOfEvil: He has a noticeable mustache to compliment his sunglasses for a shady look, although it's subverted in that Gomez is far too complex to be considered evil.
* BetterLivingThroughEvil: PlayedForLaughs [[spoiler: when he offers Birdy to join up with him and Revi again before his battle with Nechla, he says the pay is a nice incentive. She rebukes him with a flustered face.]]
* BewareTheNiceOnes: He only engages in violence if his family is threatened or if he is sufficiently pestered. Numerous characters, including Birdy herself, find out the hard way it's not good to genuinely anger him.
* BigDamnHeroes: [[spoiler: Makes a triumphant return with Sylphia to the story to stop a rampaging Nechla from killing Birdy and Revi when all hope is seemingly lost.]]
* ChekhovsGunman: Early on in ''Birdy the Mighty II'', [[spoiler: an Ixorian with long hair is seen in a page explaining what they are. It isn't until late into ''Evolution'' we find out that is Gomez as Gray Cephon.]]
* CoolShades: He's almost always wearing an awesome pair of shades. They grant him enhanced vision and awareness of his surroundings, making them more than just sunglasses.
* CruelMercy: [[spoiler: Gives Nechla brain damage over killing her, specifically stating it would be crueler to let her live with that and the shame of failure. Plus, it's the only other option to maintain her silence in front of Revi, considering Birdy does not want Gomez killing Nechla.]]
* CurbStompBattle: He is so unbelievably strong that any fight he gets into ends with his assailant often brutalized and cowering with no effort from Gomez.
** Early on in meeting Chigira, he also simply manhandles him any time he goes into his monster form to get him to turn back to normal.
** In ''Evolution'', [[spoiler: he effortlessly defeats Nechla when she easily took down Birdy and Chigira moments before.]]
* DeadpanSnarker: Gomez demonstrates a light sarcastic streak, mainly in regards to Birdy's open suspicions over him. He also feigns some sardonic ignorance with Hikawa early on until he sees how sick he truly is and stops humoring him.
* DemotedToExtra: Egrigegiously, despite being a central character in the manga, he is barely in ''Decode'' and a borderline non-entity in ''Decode 02''.
* DragonInChief: He oversees Christella Revi's operations on Earth and she implies he has been protecting her all his life. [[CurbStompBattle We find out what that means when Birdy picks a fight with him.]]
* TheDreaded: Eventually, he becomes something of a boogeyman to Shanfa and her gang after he curb-stomped all of them at once as a warning to stay away from his family. The mere mention of his sighting then on causes them to change plans, citing they can't ever beat a monster like him.
* EvenEvilHasStandards:
** Despite turning a blind eye to the actions of some of his clients, he finds the depravity of the likes of Hikawa and Bacillus to be completely distasteful. When his attempts at diplomacy and reasoning fail with them, he takes measures to stop them from causing more harm.
** He views Capella's wanton disregard for collateral damage with disdain, musing Federation officers have quite changed since he last saw them.
** Although he is not holding Chigira prisoner, he makes sure to receive the consent of his grandmother to shelter him regardless.
* EnemyMine: When Hikawa begins to threaten all of Japan, he forms a temporary alliance with Birdy to end him once and for all.
* EnigmaticMinion: He is a complete enigma to Birdy, who assumes he must be evil due to serving Revi. As he thoroughly demonstrates this is not the case, she is left even more dumbfounded about who or what he really is.
* FamilyMan: Outside of his job, he is a devoted family man, [[MoralityPet and his Earth family means everything to him.]]
* FingerTenting: He does this frequently during moments of contemplation in his office.
* {{Foil}}: As we learn more about Gomez, it's clear no one resembles Birdy more than him despite her grievances with the man. [[spoiler: Both were mentored by and have a close relationship to Skelezzo, and just like her, Gomez was once an idealistic Federal agent. His original mission of being tasked to arrest Revi even draws parallels to Birdy's current mission. However, through discovering the truth of the world, Gomez gradually took to unscrupulous means to achieve his ideals. Birdy, meanwhile, never lost her sense of idealistic justice even in her darkest hours.]] All in all, Gomez is a male counterpart to Birdy on a darker path, but without having truly lost his heart along his journey.
* {{Foreshadowing}}: In his mock fight with Birdy, he demonstrates an eerie ability to FlashStep at such speed Birdy couldn't even tell what happened. [[spoiler: [[SuperSpeed This is his trademark ability]] as Ixorian Gray Cephon.]]
* FriendlyEnemy: [[spoiler: He gradually becomes this to Birdy. While he's still on Revi's side and does his job of showing muscle in front of her, he otherwise has no animosity towards Birdy and provides advice if not outright helping her on occasion.]]
* GentleGiant: Gomez is very tall and built like a brick house but pacifistic unless he feels his family is threatened.
* TheGlassesComeOff: When he is seriously angered or needs to demonstrate his conviction, he takes his shades off and sees others eye to eye.
* HeKnowsTooMuch: [[spoiler: In his past life as a federal agent, he was marked for death for opening up an investigation on Maxwell Peridan's leftover inquirings on the Sanctum Sanctorum.]]
* HeelRealization: After witnessing Hikawa's abuse of Chigira, he comes to understand what depraved scum he is and begins to take measures to stop him, starting with taking Chigira away from him.
* HumanAlien: Like all other Altans.
* HumanityIsInfectious: Gomez explains to Birdy when he arrived on Earth, he had nothing but his loyalty to Revi, not even clothes starting off. Through his cover job and new family on Earth, he comes to cherish his friends and family as what's most important to him.
* {{Hunk}}: While he's not this now or ugly, in his early 20s to 30s, he was definitely this, having a boyish face and chiseled physique.
* InterspeciesRomance: He is an Altan and has a human wife and daughter.
* IveComeTooFar: Invoked. [[spoiler: When Gomez blatantly expresses doubt in front of Revi, she exclaims if Gomez wants to turn on her now, he has come too far and is too complicit in her plans for it to mean anything.]]
* LastNameBasis: Gomez is almost never referred to by his first name, to the point of it being AllThereInTheManual.
* LightningBruiser: He is unbelievably fast and hits very hard despite his demonstrations of strength being restrained compared to Birdy.
* MadeOfIron: In the OVA, Hikawa unloads his pistol all over Gomez's back when he decides to shut down his operation, then stomps his bloodied back with such force it breaks the floor tiles. He later shows up to Birdy in the epilogue completely fine.
* MartialPacifist: Despite his strength, Gomez only fights if his hand is absolutely forced. He otherwise leaves violence to Revi's marionettes.
* MyGreatestFailure: [[spoiler: Cites his role in killing Maxwell Peridan as one of the greatest regrets of his life, the other being too late to stop Nechla from endangering Revi.]]
* MuggingTheMonster: As a result of his pacifistic and unassuming demeanor, numerous characters like Bacillus think they can threaten and belittle him for their demands. All of them pay the price, dearly, some with him not even lifting a finger.
* MurderIsTheBestSolution: In contrast to Birdy's idealism, Gomez doesn't really tolerate loose ends, ordering Geega and Bacillus to be killed for being dangerous liabilities. After the time skip, [[spoiler: he is adamant about killing Nechla to keep her silent against Birdy and Chigira's pleas, but relents to give her [[CruelMercy a more cruel fate.]]]]
* NakedOnArrival: In a flashback showing him crashlanding on Earth, Gomez was completely nude.
* NobleTopEnforcer: He works for the terrorist Christella Revi but harbors no real ill will. He lends advice and helps Birdy on a number of occasions. He also undermines the interests of villains like Hikawa should they prove to be enough of a threat to his values.
* NotSoStoic: [[spoiler: When Nechla repeatedly insults him and makes a gesture at tattling to Revi about his deception and of how he could grovel for forgiveness like a dog, Gomez breaks a sweat and shows visible anger.]]
* OnlyKnownByTheirNickname: As an Altan, it's highly unlikely his real name is Georg Gomez. However, even Revi only refers to him as Gomez, leaving his true identity a mystery.
* TheOnlyOneAllowedToDefeatYou: [[spoiler: This is what Gomez's relationship with Revi amounts to at its core. Originally being assigned to arresting Revi as a federal agent before being swept up in her conspiracy, he never let go of his mission. Until he and Revi accomplish their mutual goals of defeating the Sanctum Sanctorum, he will never let her die, nor will he let anyone else (Birdy) take her in.]]
* ParentalSubstitute: He becomes this to Chigira with the consent of his grandmother, freeing him from Hikawa's clutches and taking him in as his pupil and eventual surrogate son.
* PetTheDog: Frees Rodney Hughes and Chigira from Hikawa's prison out of disgust for him.
* PunchCatch: He does this in his mock fight with Birdy, subsequently breaking her arm. [[spoiler: When he meets up with Skelezzo again, the latter tries to sucker punch him as part of his signature AttackHello greeting. Gomez easily catches his fist and remarks he never changes.]]
* SharpDressedMan: He is frequently shown wearing suits.
* TheStoic: Never raises his voice or loses his calm disposition.
* StrongAndSkilled: Gomez is not vastly physically superior to Birdy, but incredibly skilled and disciplined in fighting. As Birdy's ineffectual barrage of wild attacks fails to do anything to Gomez in their first "fight," he thoroughly criticizes her for being UnskilledButStrong. He later trains Chigira to do more than just throw his weight around with his newfound powers.
* SuperSpeed: His trademark ability. [[spoiler: Moreso back in the day as Gray Cephon.]]
* SuperReflexes: Given he is likely an Ixorian and the enhanced sunglasses he wears, it's nigh impossible to get a surprise attack on Gomez.
* SuperStrength: He not only vastly outclasses Birdy in this department, but their first scuffles in all incarnations end with Gomez breaking her arm with no effort.
* ThatManIsDead: [[spoiler: Officially, Gray Cephon died under mysterious circumstances. Gomez now uses his new identity as legal grounds for Skelezzo having no warrant to arrest him, and he doesn't have much interest in doing so either.]]
* UndyingLoyalty: Subverted with Revi. [[spoiler: Gomez expresses to Birdy that although he agrees wholeheartedly with Revi's endgame, he is watching her very carefully to determine whether she herself is truly just or simply a petty criminal - at which point, he will ditch her on the spot.]] His loyalty to Chigira, however, is undying to the point [[spoiler: he covertly frees Birdy from captivity, going directly against Revi's interests, simply because it deeply hurt Chigira to see her in such a state.]]
* UnscrupulousHero: [[spoiler: Gomez is eventually revealed to be this. He might oversee Revi's work, which involves turning a blind eye to some heinous crimes, but he is always watching her to determine if she is on the just path or not. Furthermore, he is involved in a secret operation concealed even from her to similarly take down the Sanctum Sanctorum.]]
* WithMyHandsTied: In one of the most memorable scenes in the manga, Gomez agrees to let Chigira fall into Birdy's custody if she can take him down. He proposes ''only'' using his right hand to fight her, much to Birdy's outrage. What follows is Birdy throwing all her weight around with Gomez not even budging before catching and breaking her arm.
* WorldsStrongestMan: It's evident he is not only implied to be the strongest Altan on Earth but one of the strongest characters in the series. He defeats Birdy in a mock fight standing still with one arm, and other villains that attempt to pick a fight with him are left terrified after the encounter.

In ''Evolution'', the audience learns of who "Georg Gomez" is: [[spoiler: As Gray Cephon, an Ixorian, Gray was once a poor child that idolized Christella Revi for her role in fighting for Altan rights, which allowed Gray to receive a normal education. As an Ixorian, Gray was enlisted into the federal investigation bureau, [[DramaticIrony where he played a key role in ending Maxwell Peridan's uprising against the department of worship.]] Later into his life, he disappeared and secretly joined with Revi after discovering the truth of the aforementioned department and the Sanctum Sanctorum. Noted to be the strongest Ixorian ever, Gray was renowned for his strength, skill, and [[SuperSpeed unnatural speed,]] [[ExactlyWhatItSaysOnTheTin literally]] earning the moniker [[NamesToRunAwayFrom Super Speed Gray]]]]

[[caption-width-right:350:Upper left (Gnome), Upper right (Sylph), Bottom left (Undine), Bottom right (Salamander)]]
Christella Revi's PraetorianGuard, collectively described as the "shield" that protects her divine will. They more often accompany Gomez as an extra set of eyes and ears. Individually, they are extremely powerful and prove more than a match for Birdy and similar Ixorian adversaries. For more on Undine in ''Evolution'', see Sayaka Natsumi's page (spoilers!).
----
* AlchemicElementals: The four are very clearly a ClassicalElementsEnsemble that is inspired by the alchemic elementals as each one is specifically named for one and has the corresponding elemental power. Salamander [[PlayingWithFire manipulates fire.]] Slyph controls wind, [[RazorWind often manifesting as blades.]] [[DishingOutDirt Gnome]] possesses [[SuperStrength unimaginable strength]] on par with that of Ixorians. Undine [[KillItWithWater controls water]] and is nearly unstoppable in an aquatic environment.
* ApologeticAttacker: [[spoiler: Gnome tries to reason with Sayaka!Undine when he tries to detain her, making it clear he doesn't want to hurt her. But he's soon forced to stop holding back.]]
* BackFromTheDead: Undine in ''Evolution'', albeit in a very different way.
* BadGuysDoTheDirtyWork: They work primarily as assassins for Gomez when peace isn't an option. In particular, Salamander kills Bacillus and finishes off Hikawa when he gets an upper hand in his brutal fight with Birdy.
* BarbieDollAnatomy: Undine is more frequently nude than wearing any clothing, but even with the remake manga being a Seinen and casually depicting fully-drawn nudity, she has no nipples.
* TheBigGuy: Gnome is ''huge,'' towering over the already tall Gomez. And while none of them are slouches in physical combat, he is particularly specialized in SuperStrength.
* BodyguardingABadass: They primarily provide 24/7 backup for Gomez; Gomez himself is one of the strongest fighters in the series. However, they are useful in ways Gomez cannot always account for, such as surveillance or the protection of his family.
* ChuckCunninghamSyndrome: Egregiously, despite being the most prominent Marionette in the first half of the manga, Salamander never appears again in ''Evolution'' despite a few mentions.
* MeaningfulName: All four are closely named after Japan's four great spirits governing the major elements of soil, fire, water, and wind.
* OutOfFocus: After being the most recurring Marionettes in the first half of the manga, Salamander and Sylph are almost completely out of the spotlight in Evolution. Gnome and Undine, who comparatively had minimal roles in the first half, receive much more development and screentime.
* RecurringBoss: Undine in every incarnation of the story is explicitly this to Birdy, being the most vicious and battle-oriented of her brethren. It usually takes several personal fights for her to be put down for good.
* RightHandAttackDog: Compared to the other Marionettes that have integrated into human society, Undine spends most of her time patrolling through the lakes of Revi's forest HQ, killing any suspicious trespassers.
* SharpDressedMan: All of them except Undine are often impeccably dressed in crisp suits when engaging with society.
* UnusuallyUninterestingSight: Averted. Compared to Salamander and Sylph, who are indistinguishably human in appearance, the lines running on Gnome's face and his unnatural cyborg eyes should give him attention, but he wears wraps around his face and sunglasses when in public.
* WhatMeasureIsANonHuman: Just like Violin, they are much more human than machine outside of fighting, easily able to blend into society. Salamander is even shown to be able to be capable of grieving the pain Undine suffers from her fights with Birdy. Revi also treats them all as living beings rather than machines.

[[quoteright:266:https://static.tvtropes.org/pmwiki/pub/images/imageedit_30_5732697820.png]][[caption-width-right:266:[[labelnote: Younger [[spoiler: as Seichiro Hikawa ]]https://static.tvtropes.org/pmwiki/pub/images/8jupmtl_2.png]][[/labelnote]]]][[caption-width-right:266:[[labelnote: Click to see [[spoiler: him mutated ]]https://static.tvtropes.org/pmwiki/pub/images/sadzjqi.jpg]][[/labelnote]]]]
A publicly renowned biologist, secretly backed by Christella Revi's terrorist network and black ops government officials of various countries. He runs a pharmaceutical company and is also highly influential in Japanese politics, having miraculously restored Gozo Mido's failing health and subsequently gaining access to his wealth and connections.
----
* ZeroPercentApprovalRating: As the president of his own company, he is hated and feared by all his employees. Apart from some occasional reassurances to keep them in line, Hikawa does nothing to make them feel better. Unsurprisingly, the remnants of his staff are much happier under Agni after the time skip.
* AdaptationalBadass: Although the OVA Hikawa put up a good fight against Birdy, he never came close to defeating her as much as endangering innocents, and his body fell apart shortly into their fight [[ClippedWingAngel after trying to bulk up.]] Here, in their final encounter, Hikawa brandishing his katana fights evenly with Birdy in his ''human state'' and [[spoiler:''mortally wounds her'', causing her SuperPoweredEvilSide to awaken. After Tsutomu snaps her out of that state, Hikawa ''then'' undergoes a successful OneWingedAngel form and is ready for another go until Salamander blows him to smithereens.]]
* AdaptationalDumbass: In a way, Shogo is this to his OVA counterpart. While Seichiro was a sadistic {{Narcissist}} with [[SmugSnake an inflated ego]], he was composed and calculating enough to come very close to carrying out his EvilPlan. This Hikawa is such an impulsive, sadistic monster with no control of his cruelty that [[spoiler: he ultimately accomplishes ''nothing''.]] That said...
* AdaptationalIntelligence: Shogo is a considerably more talented biologist than his OVA self. Whereas Seichiro's research was doomed from the start and his ultimate plan to "evolve" humanity would have destroyed all of Japan instead, Shogo's accomplishments with genetic research lay the foundation for Agni's successful work in ''Evolution.''
* AdaptationalJerkass: While Shogo is pretty much the exact same callous asshole his other self was, [[PoliticallyIncorrectVillain a misogynistic streak]] was not a trait Seichiro demonstrated to have.
* AdaptationalNiceGuy: A minor but notable case: [[spoiler: When the audience glimpses at OVA Hikawa in a flashback, he is seen peforming horrible war crimes. This incarnation of Hikawa lacks those crimes on-screen and was even shown to be genial at a point before we gradually see his decline into cynicism and madness.]]
* AdaptationalVillainy: Though Seichiro Hikawa of the OVA was no slouch, his on-screen body count and actions were kept within the limits of a four-episode TV-13 series. As ''Birdy the Mighty II'' is a 33 volume {{Seinen}} manga series, of which Hikawa is the main antagonist [[DiscOneFinalBoss for roughly half of,]] he receives much more screentime to demonstrate his twisted personality and motives.
* AmbitionIsEvil: Hikawa possesses an unshakable desire to form a superpowered army to first violently liberate Japan from foreigners and then resume conflict against China and reclaim lands he believes are rightfully Japan's, therefore starting another world war that he is confident in winning.
* AndThereWasMuchRejoicing: [[spoiler: His ultimate defeat is met with relief by almost every person involved with him, with several characters like Chigira finally feeling they can move on with their lives.]]
* ArchEnemy: He is this to Chigira, having ruined his life and changing the course of his destiny forever. Chigira feels unless Hikawa is dead, he simply cannot move on.
* AxCrazy: A DSM-V textbook example of a psychopath, who proudly likens himself to being an apex predator in the natural food chain, and therefore allowed to hurt or kill anyone he fancies. This reaches its peak in his final battle with Birdy, where he descends into unbridled fury, shrieking like a bestial lunatic and destroying everything in his way.
* BadBoss: At best, he intimidates his scientific colleagues to keep them in line. At worst (which is near all the time), he throws the lives of his soldiers away to test "results" in droves, claiming he has a bottomless supply of disposable men readily available. Hikawa is also horrifyingly abusive towards his right hand, Lee, beating her for failure and constantly finding new ways to compromise her dignity, such as stripping her down and groping or even raping her while giving her a verbal beatdown.
* BeyondTheImpossible: [[spoiler: Hikawa, a human (albeit empowered), ''mortally wounds Birdy'', an [[SuperSoldier Ixorian]] that many aliens would have difficulty in ''scratching.'']]
* BigBadWannabe: He owes an unspecified debt to Christella Revi [[spoiler: (later revealed to be providing him the Spirits that de-aged him and advanced his research.)]], which he resents. He desires to surpass her expectations by forming his ''own'' evil immortal army. [[spoiler: Due to his [[StupidEvil impulsive stupidity,]] however, he ultimately accomplishes ''nothing'' and dies an ignoble death after all his tenuous allies and enemies unite against him.]]
* {{BishonenLine}}: [[spoiler: When he de-ages himself to somewhere around his early 20s after he goes into hiding, he becomes a pretty faced man.]]
* BloodKnight: Despite being a scientist, Hikawa is a bloodthirsty maniac that relishes in combat. With his biological enhancements, he is often seen throwing down with his failed experiments, whom he keeps chained up in his basement to rile them up for a better fight. He also has no qualms of hunting down the same monsters himself should the need arise.
* BodyHorror: His OneWingedAngel form he forcibly undergoes in his final battle with Birdy sees him looking like a hulking reptilian monster.
* CanonImmigrant: Sort of. He's based on a character created for the OVA, but as noted below, he was split into two. [[spoiler:But not really.]]
* ComedicSociopathy: Downplayed. There's nothing remotely comedic or amusing about Hikawa, but the sheer depths of his callousness once caused some of his colleagues to break out into comedic expressions when his response to de-escalating a disaster he caused is to simply propose making it worse.
* DeadpanSnarker: Hikawa snarks at everyone sans Mido in a smug way, which only further inspires resentment.
* DecompositeCharacter: His appearance and enmity with Birdy is based on the Hikawa of the OVA series, but his grandfather is the one who sports the given name of "Seichiro", with this one being named "Shogo". [[spoiler: Ultimately, subverted, as this time, Hikawa decided to pull a MyGrandsonMyself.]]
* {{Determinator}}: [[spoiler: Even when everyone turns against him and he's lost everything in life, Hikawa absolutely refuses to admit defeat until he is finally killed.]]
* DiscOneFinalBoss: Hikawa is the main antagonist of the first half of the remake manga, ''Birdy the Mighty II,'' up to half of the sixteenth volume. The remaining five volumes lack a concrete antagonist, focusing on the mystique of the Altan refugees on Earth. [[GreaterScopeVillain Christella Revi]] takes up the mantle of the primary antagonist for the second half of the manga.
* DomesticAbuse: He demeans Lee Shanfa, his secretary, in every way he can from emotional to sexual abuse.
* DramaticShattering: Like in the OVA, when Gomez reminds him of his debts, Hikawa shatters his wine goblet with two fingers after he leaves.
* EvenEvilHasStandards: Inverted. Every one of his associates is appalled by his evil, especially Gomez. Hikawa himself has no standards, whatsoever, and his depravity knows absolutely no bounds.
* EvilIsPetty: He does everything in his power to torment Shigenobu without killing him, simply because he has favor with Mido even in his demented state. From killing his troops to intentionally causing civilian disasters just so he's forced to clean up after him or suffer political consequences. Unfortunately, this backfires ''big-time'' for Hikawa when Shigenobu decides Hikawa [[TheDogBitesBack is no longer worth the hassle of keeping around]] and cuts his funding entirely.
* EvilHasABadSenseOfHumor: Hikawa has a morbid sense of humor to go with the snark. It only disgusts or creeps out others.
* EvilutionaryBiologist: His occupation. Hikawa is an incredibly talented biologist, which is why Revi and various conspiracies tolerate him. [[EvenEvilHasStandards But only for so long.]]
* FangsAreEvil: He has huge, unnatural canines that are often visible when he's flashing a SlasherSmile.
* FantasticRacism: Hikawa has a low view of aliens, viewing them as "monsters." Coming from a metaphorical and literal monster like him, [[{{Hypocrite}} that's rich.]]
* FauxAffablyEvil: Surprisingly, despite how insane and cruel he is, when addressing civilians (often to lure them into his clinic), he is capable of presenting himself in a gentlemanly and charming manner.
* ForTheEvulz: Although Hikawa does have an end goal, he commits many horrific acts of pure evil [[{{Sadist}} simply to sate his bloodlust]] or [[EvilIsPetty pester]] Shigenobu. [[DeconstructedTrope Deconstructed]] in a realistic way when his acts of gratuitous cruelty [[LaserGuidedKarma alienate all his allies, funding for his research is suspended permanently, and he is sentenced to execution.]]
* ImpaledWithExtremePrejudice: [[spoiler: He pierces through Birdy's chest with his sword in their last battle, mortally wounding her. In her [[SuperpoweredEvilSide subsequent crazed state,]] she returns the favor by impaling her ''entire arm'' through his torso.]]
* ItsAllAboutMe: He literally only cares for himself and his insane ideals. Although he demonstrates a highly courteous attitude with Mido, it's hinted Hikawa is only doing this so Mido continues to finance his work. [[spoiler: Fully confirmed in his last battle with Birdy, where he uses Mido as a distraction and tries to ''cut right through him'' to get a hit on Birdy. Birdy is horrified at how he could do that to someone who trusted him so much.]]
* {{Irony}}: Posthumously in ''Evolution.'' Hikawa, a completely selfish and evil man [[SmallNameBigEgo who thought he was much greater than he was,]] [[spoiler: happened to lay the foundation for well-intentioned Christella Revi and her allies to fight against a conspiracy far greater and eviler than Hikawa could ever have hoped to be.]]
* HatedByAll: Everyone associated with Hikawa, barring Mido, either despise or deeply fear him, often both. By the end of his tale, he has ''no allies left,'' with his weak-willed subordinates even growing a spine and turning against him.
* HateSink: Hikawa possesses no redeeming qualities whatsoever, and every sick thing he does any time he's on-screen is intended to inspire loathing from the readers.
* HowTheMightyHaveFallen: [[spoiler: As a result of his stupidity in bullying Shigenobu around, he suspends all funding for Hikawa and attempts to arrest him. In the fallout of the battle between Shegenobu's men, his small army of mutants, and Birdy and Ondine, Hikawa is reduced to a homeless fugitive deprived of resources to even control his RapidAging. He attempts to ''plead'' to Shigenobu to take him back in, to which he vehemently refuses, forcing Hikawa to make him consent through violence. Even then it doesn't last long as Hikawa is killed in a joint alliance between enemies and former allies alike.]]
* {{Jerkass}}: Besides Hikawa being a sadistic, homicidal psychopath with no regard for any life but his own, he is a smug and sarcastic man who treats everyone as being beneath him.
* KillItWithFire: [[spoiler: As he braces himself for a renewed fight with Birdy, Salamander sends a fireball towards their direction that combusts into a violent explosion, ending Hikawa for good.]]
* LackOfEmpathy: As aforementioned, Hikawa explicitly has no regard for any life but his own, and his response to Shigenobu's protests over the suffering he causes is to [[{{Jerkass}} shrug it off as his problem to clean up.]]
* LightningBruiser: Owing to his experiments, he is fast as hell, possesses supernatural reflexes, and hits hard.
* MadeOfIron: [[spoiler: Birdy punches a hole in his torso that almost tears him in half, but Hikawa regains the strength to push for a transformation.]]
* MasterSwordsman: He is incredibly skilled with the use of a personal [[KatanasAreJustBetter Nodachi,]] pulling it out on special occasions and swiftly killing his runaway experiments in one blow. He brandishes the same sword in his final battle with Birdy and gives her a battle for her life.
* MusclesAreMeaningful: Underneath his simple attire, Hikawa is ''jacked'' with muscles, which can often be seen since he fights [[WalkingShirtlessScene shirtless]] most of the time.
* MyGrandsonMyself: [[spoiler:In reality, "Shogo" is really an alias; Seichiro Hikawa was posing as his own grandson.]]
* ANaziByAnyOtherName: [[spoiler: As Seichiro Hikawa, a veteran of Imperial Japan, his end goal is to forcibly reclaim its lands from the foreign "invaders" and restore his nation to its "former glory."]]
* ObviouslyEvil: He dresses in all black, has HellishPupils, is introduced sipping wine in a decaying mansion from the shadows, and is referred to as a "vampire" by kids that snuck around his house and claimed to see someone. And that's just the ''start of it.''
* OldDarkHouse: He mainly lives in a remote ancient mansion falling apart at the seams. The house is referred to as "cursed" by children that dared to go near it. Officially, it belongs to Seichiro Hikawa, his grandfather, thus Shogo inherited it from him. [[spoiler: Considering Shogo is actually Seichiro, it's his house from the start.]]
* OlderThanTheyLook: [[spoiler: As Seichiro Hikawa whose youth was rejuvenated by Christella Revi's backing, he's pushing his 90s but looks to be in his 30s. When he takes another sip of Spirits after the ordeal with Shigenobu, he rejuvenates to look even younger, appearing to be in his 20s as a boyish man.]]
* OneWingedAngel: Unlike his OVA self, [[spoiler: Hikawa successfully makes a transformation into an all-powerful mutant on the verge of death. But before he has any chance to attack, he's killed by Salamandel.]]
* PetTheDog: He once rescued Lee Shanfa from a life of abuse and debt...although, it's obviously subverted with a vengeance when it's clear he was just looking for another human test subject with nowhere to go. When Lee becomes one of the first successful metahumans, he wastes no time abusing her any chance he gets in the most heinous ways imaginable.
* ProfessorGuineaPig: Hikawa has extensively experimented on himself, turning himself into the first successful superhuman, granting him his youth, SuperStrength, and other perks at the escalating cost of his already nebulous sanity.
* PoliticallyIncorrectVillain: In one instance he's dressing down Lee with verbal abuse, he makes disparaging remarks over her being a woman, stripping her clothes, and even grabbing her breast to mock her. He's also a racist towards aliens as aforementioned in FantasticRacism, viewing them as monsters and claiming to understand why Shigenobu sought to raise a superpowered army to possibly repel them. Interestingly, in a twisted way, he isn't, however, a racist to humans per se. Shigenobu accuses him of being a racist due to most of his experimentees being Chinese or Russian, but he rebukes him claiming it's simply more difficult to procure Japanese guinea pigs without raising suspicion. In Hikawa's mind, ''everyone'' of any nationality is equal in being experimented on by him. That said, [[MoralMyopia he views foreigners in Japan with contempt, believing they compromise its independence.]]
* RedAndBlackAndEvilAllOver: As seen in his portrait to the right, official color palettes of Hikawa paint him with a black and red motif. In-universe, he primarily wears black clothing, has jet black hair, and red wine is his signature drink.
* RapidAging: [[spoiler: If he doesn't periodically dose himself on Spirits, Seichiro will revert to being a man in his 90s. This is why he becomes desperate enough to plead with Shegenobu in giving him his lab and resources back.]]
* RapeIsASpecialKindOfEvil: He violently rapes Lee early on in making her his subordinate to assert his dominance over her.
* RichesToRags: [[spoiler: After Shigenobu takes everything from him, he's also forced into living in a filthy shithole in hiding since the former also blew up his mansion.]]
* {{Sadist}}: He is defined by his unabashed sadism in such a way it [[StupidEvil seems to even take precedence over his goals and better judgment.]]
* SanitySlippage: He regularly drinks Spirits even when he doesn't have to, and Gomez suggests knocking it off, implying it's possibly the source of his ever degrading sanity.
* SuperSoldier: The first step of his endgame is to make an army of this.
* SuperStrength: Hikawa is physically strong enough to manhandle other superhumans just like him, his failed experiments, and even Birdy.
* SlasherSmile: He sports these often with his teeth fully bared. In particular, [[spoiler: a flashback showing Seijiro first rejuvenating his youth has him flash an insane smile after he's de-aged.]]
* SmugSmiler: Hikawa is almost always seen with a smug smile, being completely unflappable even when Shigenobu turns against him. The ''only'' time he drops it [[spoiler: is when he realizes Birdy may very well kill him and [[VillainousBreakdown subsequently flips.]]]]
* SmugSnake: Hikawa believes he is better than any other living creature. He's proven, wrong, however, when that smug arrogance and LackofEmpathy takes everything he values away from him.
* ScrewTheRulesIHaveConnections: He literally believes he can get away with ''anything'' simply due to the importance of his work, and makes sure to fill out atrocity after atrocity [[EvilIsPetty so Shigenobu is forced to suffer cleaning after him.]] Ultimately, he is proven ''wrong'' in the most humiliating way possible.
* StupidEvil: Ultimately, this is what Hikawa is at his core. He has delusions of far-reaching goals, but they are undermined by his impulsive bloodlust, sadism, and actions of wanton evil until he's reduced to having nothing.
* StrongAndSkilled: In contrast to his monster minions, Hikawa is a MasterSwordsman and an expert in hand-to-hand combat, making him far more formidable.
* TakingYouWithMe: [[spoiler: He screams that he refuses to die in such an undignified way in his last battle with Birdy, and proclaims that if he is to die to his wounds, he will at least take her with him.]]
* TheSociopath: Hikawa is completely self-centered, has no conscience, no empathy for anyone or anything, is driven by a relentless lust for power, and has delusions of grandeur. He has been likened to the devil by one of his subordinates, and Birdy herself expresses disbelief how he is human.
* TookALevelInJerkass: As we see in flashbacks [[spoiler: to his earlier life as Seichiro, he was a more friendly man as a young adult but years of no progress on his work dulled him into a cynical man. After rejuvenating his youth, anything decent about him went out the window.]]
* TooDumbToLive: He knows Shigenobu holds the rights to almost all the money and resources that finance his work, which even includes volunteering soldiers for his experiments. He also knows Shegenobu dislikes him and only tolerates him for his work. Despite this, simply based on not liking the man himself, he goes out of his way to antagonize him in the most unpredictable and horrible ways imaginable until Shigenobu predictably has enough and takes everything away from Hikawa.
* VillainousBreakdown: [[spoiler: He only finally falls apart when Birdy nearly kills him, unleashing the monster that's always lurked underneath.]]
* VillainousLegacy: [[spoiler: Although he's long dead by ''Evolution'', his actions cast a massive shadow over the story and many surviving characters that suffered at his hands. Muroto describes it as a "curse."]]
* VillainWithGoodPublicity: He is famous in Japan and runs a respected pharmaceutical company. [[spoiler: He loses this reputation when Shigenobu marks him as a fugitive following the disaster at his underwater facility.]]
* WeHaveReserves: He throws away the lives of soldiers and experimentees by the ''hundreds'', always rationalizing he will obtain more test subjects. Unfortunately, when he eventually believes he can abduct those with living families, Shigenobu finally turns on him once Hikawa makes it clear to his face he cares nill for the consequences.
* WineIsClassy: He is often seen with a glass or bottle of red wine at hand, which adds to his sophisticated look on the surface.
* WhatTheHellAreYou: When Hikawa lays out a speech detailing his goals to a demoralized Akutsu, the man says this verbatim to Hikawa in complete disbelief of who or what he exactly is.
* WouldHurtAChild: As Chigira is at the center of advancing his research, he tortures him with the most heinous experiments imaginable simply to test his limits.
* WouldHitAGirl: He routinely sexually and psychologically abuses Lee on top of often beating her.

!!Lee Shanfa
[[quoteright:266:https://static.tvtropes.org/pmwiki/pub/images/imageedit_1_3295191487.png]]
Hikawa's secretary and right-hand enforcer, as well as one the first of the successful superhumans produced. Her blood sampled as Type-L is what mass produces Hikawa's current super soldiers, but it is inferior to Type-C, sampled from Chigira Kazuyoshi. Lee is set to recapture Chigira, but she develops a personal interest in the boy.
----
* AllLoveIsUnrequited: As a person prior to her transformation, she was in love with Hikawa for rescuing her from her terrible life, believing he would never hurt her. He would obviously never return any affection for her, and of course, he would do more than just hurt her.
* BigBadWannabe: Lee eventually grows fed up with Hikawa and tries to strike out on her own with the fundamentals of his plans, but whatever she was trying to accomplish is personally squashed by Gomez to bury anything related to Hikawa for good.
* DarkAndTroubledPast: From what we once see of her recurring nightmares, Lee lived in poverty and was in debt to the wrong people.
* TheDragon: Serves as this to Hikawa until his insane abuse causes her to go off on her own.
* FanDisservice: She strips naked in front of Chigira upon meeting him the first time, but then promptly undergoes a monstrous transformation to provoke him into doing the same.
* FullFrontalAssault: Lee frequently fights completely naked, but given her animalistic tendencies from Hikawa's experiments, it's likely she doesn't care about nudity taboos anymore.
* KilledOffScreen: If there were any doubts to Chigira killing her, she never appears again in Evolution.
* MistreatmentInducedBetrayal: The degree to which Hikawa abuses Lee predictably has her abandon him, starting a gang of her own and wanting nothing to do with him.
* SinisterNudity: Often seen nude while fighting... One of her goals was trying to force Chigira into a monstrous transformation by any evil method whether it be strangling him or threatening the lives of the household he resides in.
* TheVamp: She seduces Akutsu into aiding her instead after he betrayed Hikawa to Shigenobu.
* TheWorfEffect: Despite being Hikawa's right hand and a superhuman, she frequently gets her ass kicked; she gets manhandled by Capella during her investigations, and later absolutely shredded by Sylphia in a bold attempt at barging into Gomez's home to retrieve Chigira. Chigira under Gomez eventually learns how to fight, and he easily takes down Lee.
* WouldHurtAChild: Psychologically. She repeatedly tries to get Chigira to embrace his monstrous side through emotional manipulation.

A senior official of the Japanese government. He leads the special forces defense agency (JSDF) and is involved with Hikawa's superhuman program, providing him resources and covering up loose ends. He is an old favorite of Gozo Mido and a rival to Hikawa for his favor.
----
* AntiVillain: Shigenobu harbors no megalomaniacal delusions, only seeking to bolster national security in the face of a possible alien invasion.
* AFatherToHisMen: He cares deeply for his men and is outraged by Hikawa's callous regard for their lives.
* BullyingADragon: On the receiving end of this. Hikawa brazenly believes because he curries favor with Mido, he can pettily torment Shigenobu all he likes. Despite Shigenobu reminding him ''he'' is the one providing him ''all'' his resources and security, Hikawa mocks him and continues to do as he pleases. Unsurprisingly, Shigenobu has his limits and decides to dispose of Hikawa sooner than later.
* CantKillYouStillNeedYou: He's planned to kill Hikawa a ''long'' time ago, considering only doing so when his research on superhumans is concluded. In the past, Mido requested Shigenobu to get along with him, knowing he resents him. He begrudgingly complied, but his patience eventually runs out.
* CorruptPolitician: He is deeply involved in an illicit conspiracy that produces bioweapons.
* DespairEventHorizon: Post-timeskip, [[spoiler: the stress of losing Mido and inability to cope with the horrors he endured with Hikawa sent Shigenobu rocketing into a psychological breakdown, and he was subsequently sent to a mental asylum before eventually being released.]]
* EvenEvilHasStandards: Everything about Hikawa shakes Shigenobu to his core.
* GetOut: [[spoiler: When Hikawa crawls back to Shigenobu out of hiding and pleads to take him back in, Shigenobu is impressed by his hubris and sics his men on him.]]
* HesBack: His fighting spirit is renewed when the Federation officially arrives on Earth.
* NightmareSequence: In ''Evolution'',[[spoiler: Shigenobu is plagued by nightmares of Hikawa's cruelty long after his death. A dream he has involves Hikawa betraying him and his monsters tearing him apart.]]
* PoliticallyIncorrectVillain: He justifies the homeless being used in inhumane experiments for the super soldier program, citing them as "trash" that provided nothing to society beforehand. Shigenobu further goes on to mention the apathy society has for the homeless from his own experiences in an attempt to rationalize himself not being not so different from the average person.
* RichesToRags: [[spoiler: Mido's death and the scandal around Hikawa leaves Shigenobu homeless in ''Evolution''.]]
* TeethClenchedTeamwork: Shigenobu tolerates Hikawa more than he should, but only because he recognizes the value of his work and because he obliged Mido's request to try to get along with him.
* TheDogBitesBack: [[spoiler: Once his patience with Hikawa runs out, he puts out an arrest warrant and seizes all his assets. In the fallout of Ondine and Birdy's battle at his underwater facility, Hikawa is reduced to a street bum with nothing to his name.]]
* VillainHasAPoint: Although the scene is not intended to make him seem too sympathetic, flashbacks to Shigenobu's life as a bum shows he does have a point in how Japanese society unfairly holds the homeless in contempt.
* WellIntentionedExtremist: After sightings of aliens in his country and seeing the destruction the likes of Birdy and Capella can cause, Shigenobu sought to bolster national security with superhumans to combat a possible invasion.

A chief scientist at Hikawa Chemistry. He administers the Spirits and works closely with Hikawa on its development.
----
* AffablyEvil: Despite being a fairly amoral scientist, he is approachable and liked by others in his circle compared to [[HatedByAll Hikawa.]] He loses the affability part in ''Evolution'', becoming more irritable as a person.
* BeardOfEvil: He grows a beard during the time skip to coincide with becoming more villainous.
* ButtMonkey: He's constantly bullied by Hikawa. Later, he is similarly bossed around by Lee sexually and psychologically.
* TheDogBitesBack: [[spoiler: Betrays Hikawa to Shigenobu when he can't take his evil anymore.]]
* EvenEvilHasStandards: Despite having no qualms of being involved in Hikawa's research early on, his escalating depravity gradually takes its toll on Akutsu's conscience until he's eventually completely worn down. Subverted after the timeskip, where Akutsu becomes a thoroughly despicable individual.
* ForcedIntoEvil: It's made clear that regardless of how he feels, Hikawa will not take his resignation. [[spoiler: After Hikawa seemingly dies, Shigenobu reassures Akutsu he isn't going to hunt him down.]]
* ForScience: He is fascinated by Hikawa's work, and this is why he sticks around [[ResignationsNotAccepted for the most part.]]
* NervousWreck: Akutsu is a weak-willed man that is easily intimidated into subordination.

An ancient man from Manchuria since the reign of Imperial Japan. Mido is an extremely influential politician and businessman, but due to being over one hundred years old, his health was irreversibly failing until Shogo Hikawa restored his youth. He was close friends with Seichiro Hikawa, Shogo's grandfather, and views his grandson favorably. However, something seems ''very'' off about Mido in the present...
----
* AmbiguouslyEvil: [[spoiler: Due to the nature of how he is post-recovery, it's uncertain if anything he does after afterward can be said to be his own volition.]]
* AlasPoorVillain: For a measure of "villain" considering his state of mind, [[spoiler: but he meets a pitful end feebly, tearfully reaching out for Hikawa's corpse in the burning wreckage of his manor. He is given this treatment by his friends and Shigenobu, [[MercyKill who finally decided to let him go with how far gone he is.]]]]
* AxCrazy: [[spoiler: Hikawa's faulty experiments to prolong Mido's life has turned him into a monster in human form. He constantly hungers for human flesh and cannot control his libido.]]
* DeathOfPersonality: [[spoiler: Although his memories remain intact, his advisor makes it clear to Shigenobu that Mido was never the same since Hikawa's treatment, being an entirely different man in personality. This is the reason they ultimately decide to let him die with Hikawa in the assault on his manor.]]
* DirtyOldMan: Played for absolute horror. [[spoiler: His monstrous libido as a result of Hikawa's treatments sees him unable to control himself in any way, demanding waves of prostitutes that he either tears apart or devours after he's through having sex.]]
* EvenEvilHasLovedOnes: [[spoiler: He truly saw Seichiro as his best friend until the very end.]]
* EtTuBrute: [[spoiler: He is horrified and feels deeply betrayed when Hikawa attempts to chop right through him to kill Birdy.]]
* {{Gonk}}: He looks like a toad, with a big mouth and gag-like lips. [[spoiler: Fitting, his monstrous form is akin to that of a salamander, using its massive mouth to devour people whole.]]

* ALighterShadeOfBlack: Although still a sinister corporation dabbling in immoral science, Agni is notably more redeeming and complex as an organization without a megalomaniacal bastard like Hikawa at the helm.
* AntiVillain: Discussed. While involved with illegal human experimentation, with many of its employees not being kept under the dark over it, Agni is still a large corporation with people of all different kinds of morals and motivations joining it. As Revi notes, as the company continues to grow larger, she will inevitably be unable to control everyone to her desires. This is why she contemplates soon taking the fruits of its research and finally departing Earth for her endgame.
* AmbitionIsEvil: Tsubaki and Ackerman both desire to exploit the alien crisis and Revi's influence to expand US and Japanese influence as a singular world superpower.
* EvilInc: Agni is once again a pharmaceutical empire that performs horrendous human experiments under the cover.
* EvilPaysBetter: It's repeatedly mentioned they treat their employees incredibly well, with compensations and a very high salary. Some of its disgruntled workers refuse to quit even under pressure from Birdy due to the pay.
* FatBastard: Pencil, doubling with FourEyesZeroSoul, works with Shyamalan on militarizing Marionettes. He is also responsible for weaponizing alien technology provided by the Empire remnants.
* MurderIsTheBestSolution: In regards to whistleblowers and traitors. They ''will'' hunt you down, something not lost upon its general workers even with their cover stories.
* SinisterSchnoz: Ackerman has a comically large nose and is a ruthless Pentagon agent.

!!Satyajit Shyamalan
->'''Voiced by:''' Creator/KenichiSuzumura (Japanese), Creator/ToddHaberkorn (English)
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/01_06.jpg]]
The CEO of PMI (Playmaker Industries), an Agni-affiliated neuroscience corporation that overtook Nakasugi Industries to advance its research. Originally debuting as the primary antagonist of the first season of ''Decode'', Shyamalan was introduced to ''Evolution'' in the sixth volume. For everything on his role in the manga, see Sayaka Nakasugi's entry.
----
* ZeroPercentApprovalRating: [[spoiler: Unlike his ''Decode'' self, his alternate world self in the manga was noted to have very bad PR, in and out of his own company.]]
* AdaptationalLateAppearance: He appears in volume six of ''Evolution'', ''twenty six'' volumes late into the manga saga compared to his episode one debut in ''Decode.''
* AdaptationalSexuality: [[spoiler: His alternate world self is gay in the manga.]]
* AdaptationalUgliness: A very downplayed case. In the manga, he is still handsome, but his more withered facial features indicate he is believably OlderThanHeLooks.
* AlliterativeName: '''S'''atyajit '''S'''hyamalan
* ArmsDealer: He is behind the production and advancement of Marionettes, selling them to militaries across the globe.
* AxCrazy: Even not taking his insane philosophies and motives into account, Shyalaman thoroughly proves to be a deranged man whose polite exterior barely conceals the homicidal monster lurking beneath the shallow surface.
* BigBad: [[spoiler: His alternate self is this of the rebooted manga, and the concept of the character is retroactively this as well for the entire franchise.]]
* BigBadWannabe: In ''Decode'', [[spoiler:He falsely believes he's in full control of the Ryunka and wants to use it to reduce humanity to a small amount of "worthy" survivors. He winds up being one of the first victims killed by its rampage at full power.]]
* BitchInSheepsClothing: Good grief. He's an expert at looking like an open, charming, boyish young executive while plotting to wipe out large chunks of the human race. It's telling that when he wants to [[spoiler:get Sayaka on his ship and away from Tsutomu]] all he has to do is tell the two of them that he's there to help and they believe him almost immediately.
* CanonImmigrant: As aforementioned, he debuted in ''Decode'' as a major character but eventually found his way into ''Evolution'' a while after ''Decode'' ended production.
* ChildProdigy: According to his backstory, he was a child prodigy. Naturally, as an adult, he is the CEO of various corporations and lives the high life.
* TheChosenOne: Deconstructed with Shyamalan, who is evil precisely because he thinks he's the chosen one in question and the only ones who matter are him and those he considers equally special.
* CompositeCharacter: The basis of his character and role in the story draw significant parallels to both Seichiro and Shogo Hikawa of the OVA and ''Birdy the Mighty II.''
* CorruptCorporateExecutive: He has twisted a neuroscience company that intended to advance A.I technology for helping humanity into a weapons manufacturer that creates killing machines to fuel conflicts across the globe.
* CreepyDoll: Shyamalan has a collection of them in his office that he enjoys caressing.
* DeathByIrony: For all his talk of natural selection and being one of "the Chosen", he ironically [[HoistByHisOwnPetard ends up not being one of the "chosen ones"]].
* DissonantSerenity: Has this down to an art. He once compares his joy at [[spoiler:awakening the Ryunka]] to that of getting a soccer ball as a little boy. And then there's the fact [[spoiler: he calmly and politely broadcasts his genocidal speech to the world.]]
* DemotedToExtra: A notable subversion. While Shyamalan has vastly lesser screentime in ''Evolution'' compared to ''Decode,'' only appearing in volume six and thirteen (the final volume), the importance of his role there [[spoiler: retroactively makes him the true chief antagonist of the ''Birdy the Mighty'' universe that includes previous continuities LeftHanging.]]
* DisproportionateRetribution: His response to a subordinate concerned over his safety is to point a gun at him, claiming he does not need to worry of safety when he is the "chosen one,"
* DoesThisRemindYouOfAnything: Shyamalan's treatment of Sayaka when [[spoiler:she goes onto his boat seems very much like date rape, considering he first convinces Tsutomu and Sayaka to trust him with Sayaka's safety, and then proceeds to make Sayaka dress as a bride (Capella even points out that if she didn't know better she'd say he was hosting a wedding) and offers her a drink that knocks her out...]] Made even worse by the fact that Sayaka is in high school, meaning that she'd either be underage or just barely of age.
* DullEyesOfUnhappiness: Whenever the audience get a closeup of his eyes, we see Shyalaman to have these, reflecting his soulless and sociopathic nature
* FaceOfAnAngelMindOfADemon: His pretty looks hide a monstrously evil, soulless personality.
* FalseReassurance: [[spoiler: When taking Sayaka into his custody after murdering her grandfather, he claims he'll take care of her to Tsutomu. Given his ominous wording of "cultivating her", his pupils shrinking and him flashing a SlasherSmile, Tsutomu is very disturbed.]]
* FauxAffablyEvil: On the surface, he can present himself as a courteous gentleman with the best interests of humanity in mind, [[VillainWithGoodPublicity earning him unanimous support from world leaders as a shining example of a human being.]]
* FearlessFool: He is completely flippant to danger or even death, believing as the "chosen one" he is destined to survive anything. [[spoiler: He is wrong.]]
* FreudianExcuse: As a child, he was the only person in a gathering of 4000 others to survive a massive terrorist bombing. The news made headlines and he was subsequently taken in as a ChildProdigy, fueling his twisted obsession with social darwinism as an adult
* TheGlassesComeOff: Whenever he gets particularly unhinged, he calmly takes off his glasses and typically flashes a NightmareFace.
* AGodAmI: [[spoiler: His alternate world self's plan was to exploit the Nakasugi family's neuro research to elevate himself to a god on earth.]]
* GoodEyesEvilEyes: Shyamalan toys with this--he's a BitchInSheepsClothing so his eyes normally look soft, innocent, and cute, but there are a number of instances in which they switch to looking more evil, especially when he removes his glasses.
* HairTriggerTemper: He is incredibly irritable, which results in him often easily lapsing into a murderous rage.
* HoistByHisOwnPetard: Tried to control the Ryunka, a weapon capable of killing everything on a planet. [[spoiler:[[TooDumbToLive He was literally in the same room with a not fully-mature Ryunka while messing with it]] in his efforts to control it and was one of the first to die in its rampage.]]
* HumansAreTheRealMonsters: [[spoiler: With the reveal of the alternate universe, its fate, and the nature of the Sanctum Sanctorum, Shyamalan is more monstrous than any other alien or being seen in the franchise, his avaracious desire for power effectively destroying an entire universe.]]
* ItSucksToBeTheChosenOne: Shyamalan gives such a speech, but as mentioned, he's a deconstruction.
* KnightTemplar: He sincerely believes his plan to wipe out most of humanity to be in its best interests to advance the species forward.
* LaughingMad: He frequently cackles a deranged laugh when he doesn't have to put on an act of civility.
* LiterallyShatteredLives: [[spoiler: He is glassed by the Ryunka.]]
* MaskOfSanity: As aforementioned in AxCrazy, Shyamalan is decent in keeping up a mask of politeness, but he's always only one step off flying into a homicidal rage.
* NearVillainVictory: [[spoiler:As it happens, actually does get his hands on the Ryunka and does succeed in awakening it. Too bad he can't control it as well as he thought he could....]]
* NightmareFuelStationAttendant: Big time. He is probably the scariest villain in ''Decode'', despite being the only antagonist who's ''human'' in a series crawling with alien criminals including [[BodyHorror a guy with the ability to devour people and absorb their memories]] and a SerialKiller who murders his enemies so violently [[EvenEvilHasStandards he puts even hardened terrorists off]]! It's even more disturbing because [[FaceOfAnAngelMindOfADemon he doesn't look it. At all]].
* OffWithHisHead: [[spoiler: After he's glassed by the Ryunka, his head rolls off his body and shatters on impact, his eyeballs rolling out neatly before melting.]]
* OlderThanTheyLook: If it's truly the case that [[spoiler:he was a casualty of the Six-Day War]], as this would place him in his mid-to-late forties (or even as old as fifty) but he looks no older than late twenties or early thirties.
* PetTheDog: He adopts an infant that solely survived one of Sayaka's initial Ryunka fueled rampages, reasoning they are kindred spirits in being "chosen ones." It's the only genuinely good thing he does on-screen, even if it is twisted by his insane reasonings.
* ProperlyParanoid: Shyamalan doesn't trust Capella at all. [[UnwittingPawn He has good reason to be paranoid.]]
* PsychoticSmirk: He frequently flashes these when he's not practicing DissonantSerenity.
* RaceLift: His original counterpart, Seichiro Hikawa is Japanese, while Shyamalan is AmbiguouslyBrown.
* ScaryShinyGlasses: Sometimes his glasses reflect off as these to emphasize how creepy he actually is.
* SharpDressedMan: He is almost always shown wearing expensive tailored suits.
* SlippingAMickey: To [[spoiler:Sayaka]]. It wasn't alcohol, after all - that would be illegal.
* SmugSnake: As a result of his beliefs and success in life, Shyamalan is incredibly haughty and arrogant. Despite his boasts to Gomez of being the chosen one, he is eventually proven to be out of his depth and not as great as he thinks he is.
* TheChooserOfTheOne: [[spoiler:He's the one who chose Sayaka to be the carrier of the Ryunka.]]
* TheSocialDarwinist: His philosophy in life is summarized as believing only a fraction of humanity that survives impossible odds to be worthy of life, and that the rest is unworthy and deserves to perish. It's as every bit as insane as it sounds, and it is even lampshaded in-universe as crazy.
* TheSociopath: While Shyamalan does have a sliver empathy for those he believes are like him, he has complete disregard for all other life around him.
* UnwittingPawn: Ironically, for all his boasts of being the chosen one, it never really occurs to him he's simply being used by his alien benefactors, despite being given the freedom to do what he basically pleases.
* UsedToBeASweetKid: Questionable since we don't get to see what he was like as a child, but his mention of being excited to get a soccer ball suggests that if nothing else, he used to be human enough to enjoy normal children's hobbies.
* VillainWithGoodPublicity: As shown through computer documents about him, he is very well-regarded publicly and recognized by the U.N. and other world leaders as a great man. [[spoiler: After his publicized MotiveRant and subsequent murder of millions, he is posthumously villified.]]
* WhatHappenedToTheMouse: By the manga's end, [[spoiler: we never find out what became of his prime world counterpart.]]
* WrongGenreSavvy: Shyamalan demonstrates a pretty good understanding of concepts such as TheChosenOne and OnlyTheChosenMayWield, for example, but he lives in a world where they don't apply and his behavior just makes him a bad person.

[[folder:Robert Woodman (massive spoilers)]]
!!Robert Woodman
Sayaka's husband from the alternate universe. A close affiliate and sponsor of Shyamalan, it was Robert who sought out Sayaka's talent overseas. Their relationship was an unloving one, with Sayaka still in love with Tsutomu and Robert emotionally controlling her through her lack of spine. He and Shyamalan eventually ousted her from the company, seizing her research and accidentally ending the world in their reckless desire to expand their power.
----
* BitchInSheepsClothing: Although Robert presents himself as an unassuming and well-meaning man, it's all an act to hide his ruthless ambitions.
* CrazyJealousGuy: He is very possessive of Sayaka and deeply resents Tsutomu for his relationship with her. It's to a point Sayaka believes Robert has been looking through her emails to see if she's still in touch with him.
* GodhoodSeeker: He proclaims to Sayaka with their achivements in scientific fields, they could become gods on earth.
* GoldDigger: Robert claims to Sayaka he has no genuine bond with Shyamalan and is just using him to get rich.
* GreaterScopeVillain: Along with Shyamalan, his heinous experiments laid the groundwork for all the conflict seen in the franchise
* WeCanRuleTogether: With Sayaka, he implores her to join him and Shyamalan in their unethical research. When she refuses, they kick her out and take everything from her.

[[quoteright:185:https://static.tvtropes.org/pmwiki/pub/images/imageedit_2_5061828000.jpg]][[caption-width-right:185:[[labelnote: Click to see him post-recovery]]:https://static.tvtropes.org/pmwiki/pub/images/altoros.PNG]][[/labelnote]]
The 192nd generation emperor of a now scattered Altan empire. He is a young man but dying of illness as a result of being the product of a failing cloning process used to produce new heirs with Etania's blood. Altoros forms an alliance with Christella Revi hoping to restore his health. He soon gets his wish when Revi successfully copies his consciousness into a Marionette. Now in a healthy body, Altoros seeks to solve the dilemma of producing a successor.
----
* AndNowYouMustMarryMe: To Birdy after learning of her bloodline.
* AffablyEvil: Altoros is incredibly polite and graceful to others, even commoners, despite his status as an Imperial prince.
* BrainwashedAndCrazy: [[spoiler: Revi brainwashes him when he wholly opens up to her, making absolutely sure he serves her every need.]]
* {{Cyborg}}: His consciousness copied now inhabits a Marionette while his old self is set to perish.
* FatalFlaw: His undying trust in Revi, which his advisors even warned against. He is so grateful to her for giving him the life he never had that he even declares her his surrogate mother while professing his loyalty. [[spoiler: It never occurs to him Revi could just be using him.]]
* HeelFaceBrainwashing: [[spoiler: Revi's influence on his mind ensures he gives up his ideals of revenge and conquest after a large portion of the Federation is left stranded on Earth.]]
* {{Keet}}: He is a very lively kid once he obtains his new body.
* PoliticallyIncorrectVillain: He has some very archaic views, telling Birdy as a "commoner" she has no right to object to his desires. Given he was brought up in an Imperialist dynasty, it makes sense he thinks like this.
* RapeIsASpecialKindOfEvil: Since he's not even capable of intercourse in his Marionette body, he plans to impregnate Birdy through artificial insemination via his old body.
* {{Revenge}}: His singular, one-sided goal in life with all his supporters is to get revenge on the Federation. [[spoiler: Deconstructed in that this leads him to be easily tricked and exploited by Revi.]]
* SuccessionCrisis: Since he was dying, it was a question of who would succeed him with Wyrm being ill fit. The issue is not resolved even after he gained a new body, as his Marionette form is unable to procreate.
[[/folder]]
[[folder: Wyrm Tail]]
!!Duke Wyrm Tail of Eon
[[quoteright:233:https://static.tvtropes.org/pmwiki/pub/images/eacsohh.png]]
A prince of the Etania royalty and former lord of Eon, a vassal planet of the Altan Empire before it was claimed by the Federation. Due to being of low nobility, he is not considered a candidate for succeeding Altoros. He causes problems for Birdy and Tsutomu when he intercepts the medical ship arriving to resolve their mental fusion crisis, holding the crew hostage and working to sway them to his side.
----
* AffablyEvil: He has the personality of a sociable playboy despite more or less being a pirate.
* AmbiguouslyEvil: While there is something very sinister going on about him, he brings up good points about the corruption of the Federation. His goals, independent of Altoros and his league, are a mystery, but he assures his hostages it doesn't involve revenge or conquest.
* AManOfWealthAndTaste: The interior of his ship is nothing short of exquisite royalty, complete with a lavish garden and expensive food.
* NoMrBondIExpectYouToDine: Instead of killing or torturing them as they assumed, he treats his new "guests" to the finest food and drink while conversing about himself and his motives.
* YouCantGoHomeAgain: Obviously not himself since he would be executed, but when questioned about keeping slaves on his ship, he reasons his servants returning to Eon wouldn't bode well for them knowing the persecution and abuse that awaits those that serviced the old Altan empire in any way.
* WhatHappenedToTheMouse: He...just disappears from the plot, as possibly the biggest loose end of Evolution's hurried ending. The only impact he can be said to have on the story is he ensures Tsutomu and Birdy can no longer separate on time. [[spoiler: And with the collapse of the Sanctum Sanctorum, it's permanent.]]

!!!Federation Department of Worship
[[folder:Sanctum Sanctorum (massive spoilers)]]
!!The Powers That Be, Yggdrasil
[[quoteright:137:https://static.tvtropes.org/pmwiki/pub/images/max_0.PNG]]
A council of ancient extraterrestrials at the center of worship from a fringe Federation department. Originally briefly seen in a flashback to Birdy's past, their importance is unraveled near ''Evolution's'' endgame. As the reader learns through Maxwell and Gomez, the aliens predated even the first born Altan and have been manipulating the flow of history since the dawn of time: According to Gomez, they are behind the creation of the original Altan monarchy, the Etania Empire, as well as the production of Ixorians. Today, they continue to manipulate the flow of politics behind the department of worship, spinning wheels of racial tensions through Christella Revi as a scapegoat for numerous atrocities. While their true motives are shrouded in mystery, their actions make them the GreaterScopeVillain of the entire franchise.
----
* AlternateUniverse: They come from a universe that was spawned by Shyamalan inadvertently opening a wormhole that tore apart the fabric of reality. From there, they used genetic data left over from the apocalypse to effectively restart life. The same universe that houses the aliens in the galaxy at large eventually discovers the Earth seen in the story through the Sanctum Sanctorum's efforts at interdimensional travel to find their "mother" Sayaka Nakasugi.
* AIIsACrapshoot: They are A.I constructs spawned from Sayaka Nakasugi's research from another reality, her research having been stolen and exploited by Shyamalan to take over the world. Despite their noble intentions of order through their methods in contrast to Shyamalan's intentions, they have caused untold amounts of suffering through cycles of silencing people and even whole races seeking the truth on the origins of their universe.
* AttackOfTheFiftyFootWhatever: They are are ''huge,'' towering over all of Japan in their invasion of Earth. That form as well as their general appearance is actually a holographic projection from their real forms as computer terminals.
* AGodAmI: As a likely imprint of Shyamalan's ideologies, they constantly assert themselves as gods.
* FlunkyBoss: As immovable A.I terminals, they have next to no fighting ability but have hundreds of Berserker androids on standby to defend them. When Birdy and Gomez destroy all of them, they are completely helpless.
* TheEvilsOfFreeWill: Their reasoning for everything they do and lording themselves as gods with mortals to their worships is because they believe without free will, sentient life will not repeat the same mistakes of Shyamalan.
* HeKnowsTooMuch: They go to genocidal lengths to ensure no one knows the truth of them or their goals to uphold order.
* WellIntentionedExtremist: At its core, their intentions are genuinely noble, but their methods are not. And their beliefs are at odds with Revi, who believes humanity should adapt to think for itself, regardless of the consequences.

[[folder:Nechla Geeze]]
!!Pontiff Nechla Geeze Altera
->'''Voiced by:''' Creator/RyokaYuzuki (Japanese, ''Decode''), Creator/StephanieYoung (English)
[[quoteright:287:https://static.tvtropes.org/pmwiki/pub/images/imageedit_14_2965907720.jpg]][[caption-width-right:287:[[labelnote: Click to see [[spoiler: her unleashed form]]:https://static.tvtropes.org/pmwiki/pub/images/frkitht.png]][[/labelnote]]]][[caption-width-right:287:[[labelnote: [[spoiler: Second Form]]:https://static.tvtropes.org/pmwiki/pub/images/nechla_t.PNG]][[/labelnote]]]][[caption-width-right:287:[[labelnote: [[spoiler: Final Form]]:https://static.tvtropes.org/pmwiki/pub/images/nechla_t_3.PNG]][[/labelnote]]]]
An Ixorian Inquisitor in the department of worship. She is also a feared assassin and capable detective tasked with the elimination of Christella Revi. Nechla makes recurring appearances throughout the manga as a notable person in Birdy's life, observing her progress with her lover Kashu since childhood. Although she appeared as a tenuous ally to stop the Federal Army's corrupt actions in the ''Spring Festival'' arc, she reappears a major antagonist in ''Evolution.''
----
* AdaptationalJerkass: As a result of ''Decode'' never being completed, most of the humanizing elements to Nechla's character from the late volumes of ''Evolution'' are not present. On the other hand...
* AdaptationalNiceGuy: Nechla's homicidal tendencies are considerably toned down in ''Decode,'' and as a result of her backstory not fully being incorporated, she is more socially adjusted and mentally sound.
* AlasPoorVillain: In the end, [[spoiler: Nechla wasn't willingly evil in almost anything she did and finally finds peace in death after murdering her lover. The grief of killing her sends Birdy into mental shock.]]
* AloofAlly: In the instances she helps Birdy, Nechla is very distant and makes it clear she's on her own business.
* AmbiguouslyEvil: A constant of her character. She is working for the Sanctum Sanctorum but repeatedly shows in privacy that she disdains them and finds sermons tiring. Nechla also demonstrates plenty of noble traits, stopping the Federal Army's actions of her own volition and having amicable relationships with the Altan Refugee Network, stating she has no reason to harm them unless her superiors demanded it. This is a central focus of her character in the ninth volume, where her amnesiac state reveals Nechla was effectively indoctrinated into a cult and what Birdy could have become without loving support in her childhood.
* AttackHello: In a much less friendly way than Skelezzo. She greets Birdy on Earth by launching a volley of needles at her, stating she was just testing her reflexes when she gets mad over it.
* AttackOfTheFiftyFootWhatever: [[spoiler: Like Birdy before her, the angrier she gets in her brainwashed state, she turns into a kaiju-like monstrositiy of pure bio energy.]]
* BaitTheDog: Nechla introduces herself to Birdy on Earth attacking her with seemingly lethal intent, then seems to be intent on killing Tsutomu's dad when he notices them. When Birdy questions what the hell her problem is, she claims she was just planning on putting him to "sleep." All this gives the impression Nechla is as AxCrazy as Capella. As we later learn, her weapons are capable of inducing sleep without serious harm and Nechla is thoroughly a NobleDemon.
* BadassInDistress: With Birdy, she spends most of volume eight as a captive of Revi.
* BattleInTheCenterOfTheMind: [[spoiler: Her conscience is literally split into two personalities fighting for control after her brainwashing.]]
* BigNo: [[spoiler: When Gomez decides to give her brain damage instead of killing her.]]
* BlackEyesOfEvil: [[spoiler: The further her mental state deteriorates under the Sanctum Sanctorum's brainwashing, her eyes turn completely black with slitted pupils.]]
* BoyishShortHair: She has short white hair.
* BrainwashedAndCrazy: [[spoiler: The Sanctum Sanctorum's mental conditioning of Nechla triggers when her faith completely wavers, brainwashing her back onto the path of her original objective of killing Christella Revi.]]
* BullyingADragon: [[spoiler: When Gomez is faced with the dilemma of killing Nechla against Birdy and Chigira's pleas, as she may reveal his deception to Revi in interrogation, she endlessly ridicules him over the possibility. To be fair, she doesn't care about her life and tells him to hurry up and kill her already.]]
* DarkActionGirl: She perfectly contrasts Birdy, being a cold-blooded assassin for a malevolent department.
* DarkAndTroubledPast: [[spoiler: She was indoctrinated into worshipping the Sanctum Sanctorum since childhood and envied the carefree life Birdy lived. When her faith began to waver, Nechla was severely punished and made to beg for forgiveness so she does not suffer the same fate as Maxwell Peridan. Her role was promptly repurposed into that of an assassin for her masters, being told killing "heretics" is the only way she could attain "redemption."]] After all that, it's no surprise Nechla is so screwed up deep down.
* DeathOfAThousandCuts: Needles carved from her bio armor are capable of penetrating through the bio armor of other living organisms. Although obviously fatal should she aim for a vital or the head, they induce paralysis or sleep upon hitting non-vitals.
* DeathSeeker: [[spoiler: Begs Kashu to kill her in a moment of lucidity as she's fighting for control of her mind. After killing Kashu, she feigns cruelty so Birdy absolutely kills her, and she gets her wish.]]
* DefrostingIceQueen: When Kashu introduced himself to Nechla, she was mechanical in nature and found him a nuisance. Over time, his kindness grew on her and they became lovers. In regards to Birdy, although she maintains an unfriendly to hostile relationship with her throughout most of the story, she genuinely warms up to her during their escape from Revi in volume nine.
* DemotedToExtra: PlayedWith. Although she does play a slightly lesser role in ''Decode'', it's not by much to her role in the first half of the manga. The anime was CutShort around where Nechla would have received major focus, and the closing scene emphasizes a buildup to the events of ''Evolution.''
* DespairEventHorizon: [[spoiler: Crosses it after instinctively murdering Kashu. She hardens her heart to ensure Birdy does not hesitate in killing her.]]
* TheDreaded: Birdy pleads with Revi to surrender on meeting her, fearing Nechla and saying she has no hope of surviving if she gets to her.
* DullEyesOfUnhappiness: [[spoiler: Post-brain damage, she has these in her vegetive state.]]
* EldritchAbomination: [[spoiler: Her terrifying form unleashed during her brainwashed rampage. Birdy fearfully even expresses Nechla is no longer anything resembling a humanoid. After Kashu removes the head of this form, it even further devolves into literally looking like an eldritch monster.]]
* EmotionlessGirl: As a result of her horrible upbringing, Nechla expresses she cannot feel emotions like normal people do. Only Kashu brings out feelings of love and empathy in her.
* FateWorseThanDeath: [[spoiler: What she views happening to her if she failed in her mission to capture or kill Revi, and thus she goads Gomez into killing her. Unfortunately, Gomez is aware of this as well and gives her brain damage over killing her, citing it's more fitting for her to live with the shame.]]
* ForbiddenLove: Her love for Kashu is viewed as this by her superiors, and they believe he leads her astray. As a result, Nechla and Kashu are frequently spied upon. They are also only allowed to continue their relationship if Nechla continues to perform her duties as an assassin.
* ForcedIntoEvil: As we learn more about Nechla's past, it's clear she is what Birdy would have become without the love of people like Violin and Megius: A slave to the Sanctum Sanctorum.
* GetItOverWith: [[spoiler: Goads Gomez to simply kill her instead of considering sparing her.]]
* GladToBeAliveSex: Her first time with Kashu was this, being overwhelmed by the influx of emotions, namely love, after living her life up to then as a machine.
* GlassCannon: Her needle weapons are produced from her bio armor, tiring her out to produce too many of them as well as leaving openings in her natural defenses. In extended fights, Nechla can easily get worn down and she tries to end them as soon as possible.
* HeelFaceDoorSlam: [[spoiler: Intends on defecting from the department of worship and running off with Kashu, but the sanctum's mental conditioning on her turns Nechla into a mindless slave solely dedicated to her objective of killing Revi.]]
* IDieFree: [[spoiler: As she's dying, Nechla makes peace with her split consciousness, embracing her and saying they will finally depart to a world free of pain.]]
* ImpaledWithExtremePrejudice: [[spoiler: Birdy impales her with her arm then uses Crash, killing Nechla.]]
* KillTheOnesYouLove: [[spoiler: She can't help herself and murders Kashu in his attempts to reason with her.]]
* MsFanservice: She is tall, busty, and her outfits often leave nothing to the imagination. She is also one of the few characters seen on-screen having sex and spends most of volume eight naked in a healing tank with Birdy.
* NobleDemon: She is definitely this compared to others in the department of worship, always wanting to avoid as many casualties as possible and having no real faith in her superiors.
* NotAfraidToDie: Completely flippant at the prospect of death.
* NotInThisForYourRevolution: She tells Birdy her assassination of Revi is not involved with the police or out of any personal moral obligation. His masters told her to kill Revi, and that's it. [[PunchClockVillain Nothing more, nothing less.]]
* NotSoAboveItAll: [[EmotionlessGirl Nechla]] demonstrates a comedic side in front of Birdy when she threatens she'll beat up Kashu for not coming to her rescue, exasperating Birdy.
* IdentityAmnesia: [[spoiler: After Gomez gives her brain damage, her mind regresses to a child-like state.]]
* PunchClockVillain: Nechla has no interest in any genuine worship to the Sanctum Sanctorum, and off duty is a relatively normal person.
* ShesBack: [[spoiler: Eventually pieces back her mind from her brain-damaged state. [[BrainwashedAndCrazy Sadly, it does not last.]]]]
* SparedByTheAdaptation: In ''Decode.''
* TheStoic: Comes with being an EmotionlessGirl and cold-blooded assassin.
* StrikeMeDownWithAllOfYourHatred: Invoked. [[spoiler: Nechla acts callous over Kashu's death and goads Birdy with evil rhetoric, only so she will clear her mind of doubt and end her life.]]
* {{Stripperific}}: Whether formal or casual, outside of her robes, her outfits leave little to the imagination.
* TeethClenchedTeamwork: She's not exactly fond of Birdy and vice versa. However, they irregularly find each other in times of crisis and are forced to cooperate to stay alive.
* UnstoppableRage: [[spoiler: Nothing will stop her from killing Revi in her brainwashed state, and she will trample over everything, including her lover.]]
* WeakButSkilled: By her own admittance, she is nowhere near as strong or durable as Birdy, but believes she is more refined in her fighting style.
* TheWorfEffect: Although Nechla is practically unstoppable during her assault on Revi's HQ, even easily defeating Birdy, she is completely outmatched when faced with Gomez.

[[folder:Mace]]
!!Bishop Mace
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/mace_0.PNG]]
The leader of the special assassination unit dispatched to kill Christella Revi after Birdy discovers her whereabouts.
----
* ZeroPercentApprovalRating: Despite his high standing and how conscious he is of his authority, ''none'' of his subordinates on-screen are shown to respect him, only fearing the trouble he might cause. Nechla even subverts his leadership by doing her job her own way.
* AscendedExtra: Originally debuting in ''Decode'' as a nameless pontiff overseeing an operation to control the Ryunka situation on Earth, the character was imported to ''Evolution'' with a name, defined personality, and motives.
* AdaptationalJerkass: Originally, he was just a callous one-note character that didn't care for the destruction of Earth so long as he got rid of the Ryunka. In Evolution, his personality is expanded to that of a twitchy coward obsessed with his authority and power.
* AssholeVictim: He gets his brains blown out by one of his subordinates in the middle of ranting over a justification for nuking Earth again.
* TheCorrupter: Flashbacks to Nechla's childhood also illustrate Mace was in charge of indoctrinating her into worship of the Sanctum Sanctorum.
* DeathByAdaptation: Neither he or his entire ship are taken out in ''Decode.''
* DisproportionateRetribution: He attempts to nuke Earth because, in his twisted mind, Nechla undermined his authority and made a fool of him. Mace would compromise all the Federation stands for just so he can kill Nechla through using their mission of killing Revi as justification.
* EvenEvilHasStandards: Inverted. When he fires the first orbital laser down upon Earth, his subordinates are left absolutely stunned while Mace is indifferent until he realizes he missed. When he attempts it again, his crew kills him to salvage the diplomatic crisis on Earth.
* EvilSoundsDeep: He has a very deep, booming voice in the anime.
* EntitledBastard: He's very touchy about his authority, repeatedly asserting his role as leader to force his workers into doing his bidding.
* GeneralFailure: He demonstrates to be a lousy commander in chief and Nechla undermines his authority fearing his incompetence.
* GivingSomeoneThePointerFinger: He points his finger this way when bossing others around.
* InTheHood: We never get a look at his face, only his eyes.
* ItsAllAboutMe: Everything he does is to improve or preserve his position of power. His planned second bombing of Earth is out of desperation to finish Revi so he can save face with his superiors and not get demoted for his initial screwup.
* LeanAndMean: Although he spends most of his time sitting on his throne, when he gets up, he shows himself to be very lean and hunched over.
* KilledMidSentence: He's halfway through a rant before one of his men has enough and shoots him in the head.
* MotiveRant: He explodes into these when his subordinates question him, raving about their duties to their gods, how they must "avenge" Nechla, and so on.
* NervousWreck: After his initial bombardment on Earth misses thanks to Gomez's intervention, he spends his remaining screentime as a stuttering wreck, knowing how screwed he is when the Federation gets word of what he did.
* PrettyLittleHeadShots: Averted. The blaster shot goes right through his left eye and splatters his brains all over his throne.
* SmallRoleBigImpact: He doesn't last long, but his actions make Earth's military forces recognize the Federation as a hostile force, kickstarting the war arc. There's also the fact Mace is why Nechla is the way she is now.

[[folder:Capella Titus]]
!!Capella Titus
->'''Voiced by:''' Creator/KaoriNazuka (Japanese, ''Decode''), Creator/TrinaNishimura (English)
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/01_08.jpg]]
After Birdy is temporarily suspended from duty following her accidental killing of Tsutomu, the Federation sends reinforcements to aid in her Earth investigation. Unfortunately, among those who arrive is Capella Titus, an infamous investigative agent with a history of disturbing police brutality.
----
* AdaptationalComicRelief: In ''Decode 02.'' Due to her involvement in the Ryunka disaster, Capella goes into hiding on Earth through Irma's network. There, she fumbles around trying to adjust to a new life as a cosplaying maid.
* AdaptationalEarlyAppearance: Capella makes a silent cameo in episode one of ''Decode'', already on Earth. In the manga, she appears sometime after Birdy's suspension following Tsutomu's body death.
* AdaptationalKarma: Unlike her manga self, Capella in ''Decode'' is eventually arrested and set for a trial.
* AdaptationalNiceGuy: Capella is still a thoroughly unpleasant person in ''Decode'', but she displays traits of being a {{Tsundere}} and could later be described as ''cute'', something that cannot be said for her original character. Her homicidal tendencies and sadism are also massively toned down.
* AdaptationalPersonalityChange: Although some aspects of her character remain intact, Capella is otherwise an almost completely different person in ''Decode'': she is capable of empathy, being humored, and void of the extreme sadism and bloodlust that defines her manga counterpart.
* AnArmAndALeg: Salamander disintegrates her left arm in a skirmish.
* AxCrazy: A deranged, merciless woman who prefers violence to diplomacy. She also thoroughly enjoys killing and torture.
* BigBadDuumvirate: With Shyamalan in the first season of ''Decode.'' Although their alliance is tenous at best, she provides him with leads on the lost Ryunka and encourages him to unleash it so she can justify placing Earth under Federation jurisdiction.
* BigOlEyebrows: Her prominent caterpillar brows are a notable part of her look.
* BloodKnight: Capella enjoys combat and takes pride in her record of not being injured in battle.
* TheBusCameBack: Near the end of the first half of the manga, Capella returns to Earth after fully healing her previous injuries.
* ChildSoldiers: Birdy assumed early on Capella was this due to her appearance and personality, but it's subverted when it's revealed Capella is older than her.
* ColdBloodedTorture: A huge fan of this, especially in regards to her interrogations, to the point she's been involved in scandals about this.
* CorruptCop: Capella has great influence among extremists in the internal affairs department, which allowed her to escape justice for past scandals involving crimes against life.
* TheCorrupter: In ''Decode,'' she brings out the worst in both Shyamalan and the Ryunka in Sayaka to advance her own agendas.
* CurbStompBattle: Delivers one to Shanfa during her pursuit of leads on Christella Revi.
* CuteAndPsycho: Birdy admits Capella at least looks cute when she isn't exhibiting her psychotic personality.
* DeadpanSnarker: Capella is very sharp-tongued in an unpleasant way.
* DemotedToExtra: Although she is not a minor character and her role parallels some significant aspects of her manga incarnation, Capella's diminished presence in ''Decode 02'' ultimately makes her this compared to the significance of her other self to the broader narrative.
* DestructiveSavior: She has absolutely no regard for collateral damage, setting off many building explosions during her time on Earth, something that spurs Gomez into action. This trope is later subverted when the audience learns Capella has no good intentions on Earth at all, so the "savior" bit is nixed entirely.
* DontMakeMeDestroyYou: [[spoiler: Implores Birdy to join the Federal Army's cause after she returns to Earth, as a fellow Ixorian. She makes it clear, though, if she stands in her way, she will kill her even if she would prefer not to.]]
* EnemyEatsYourLunch: She is not on friendly terms with either Tsutomu or Birdy, but helps herself to the former's house food when staying over. He even lampshades that some of it is meant to be his breakfast.
* EstablishingCharacterMoment: In the manga, Capella presents herself to Birdy as an unassuming little girl with a light sarcastic streak. After sending her off and taking custody of some criminals she detained, Birdy discusses her profile with Megius, who nervously relays her history of being involved with scandals of horrific police brutality. Birdy is outraged at how she was allowed on Earth, and the page cuts to a shot showing Capella dismembered and hung her captives, sporting a massive SlasherSmile at the sight.
* EvilCounterpart: She's Birdy if she had no scruples about murder or even a conscience.
* EvilRedhead: Has red hair and is a sadistic monster of a police officer.
* FalseFriend: Claims she is nothing but supportive of Shyamalan and only wants to be his friend, but it's made painstakingly obvious she is only using him. He doesn't trust her at all, either.
* FalseReassurance: When she arrives on Earth, she tells Birdy she'll "take care" of some criminals she detained and to go rest. What Capella did after Birdy left was torture the criminals to death while interrogating them.
* FanDisservice: She's shown naked when about to hibernate in her restoration pod, but she is severely scarred from burns and has a melted stump of an arm from Salamandel's attack.
* FauxAffablyEvil: Her polite and professional manner of conducting herself is lipservice hiding the sadistic monster underneath the surface.
* TheFriendNobodyLikes: While the other Federation officers on Earth can at least work with one another and don't mind each other all that much, none of them particularly like Capella, viewing her with a degree of contempt at best. Birdy even complains to Megius about how he could let someone like her loose on Earth, but he informs Birdy he has little authority to control her actions.
* HateSink: Unlike her ''Decode'' self, the original incarnation of Capella has no redeeming qualities whatsoever and her depravity knows absolutely no bounds.
* HiddenDepths: Despite her thuggish and homicidal demeanor, Capella is an expert in political warfare. Even without her shady connections, she exploits various technicalities and loopholes around the situation on Earth to justify the Ministry of Foreign Affairs in giving her a ride back.
* KarmaHoudini: [[spoiler: She goes into hiding on Earth at the manga's end, with Megius lamenting it is difficult to arrest her with the remnants of the army shielding her from prosecution.]]
* ThereWasADoor: Often makes her entrance through blowing up a wall than opening a door.
* GoodScarsEvilScars: When she reappears after healing up to her injuries against Salamander, her arm has grown back, but one side of her face is permanently scarred from burn damage.
* KickTheDog: In her confrontation with Shanfa and Chigira, she concludes Chigira poses no threat to her, given that he is terrified out of his wits and crying. However, she tries to kill him anyway reasoning she can't let him loose on the populace in his monstrous state.
* {{Jerkass}}: Her penchant for violence notwithstanding, Capella is quite a mean-spirited bitch and [[TheFriendNobodyLikes consequently]] earns the ire of her colleagues on Earth.
* JustFollowingOrders: [[spoiler: Exclaims she was strictly on orders to instigate the Akrabar disaster, and that ever questioning the "why" of it is a death sentence. She places all the blame on Revi for putting her into that role in the first place instead.]]
* KnightTemplar: When justifying her methods to Birdy, Capella claims everything she does is supposedly in the name of upholding order in the galaxy. This is a complete lie.
* HairAntennae: She has a couple of locks of hair sticking up in this fashion.
* {{Meido}}: Her cover while hiding on Earth in Decode 02.
* PintSizedPowerhouse: Despite her child-like height and build, she is monstrously strong and durable just like Birdy.
* OlderThanTheyLook: She's ''several'' cycles older than Birdy, much to her shock since she assumed she was a child.
* OmnicidalManiac: When she returns to Earth, she exclaims she is determined to reduce it to "a sea of hellfire."
* PutOnABus: After suffering serious injuries to Salamander, Capella leaves Earth to heal her wounds. Much later on, not long after Hikawa is killed, she reappears to Birdy on comms and resumes duty.
* RedOniBlueOni: The red to Kashu's blue, being a homicidal psychopath with no regard for legal police procedure.
* {{Sadist}}: She ''loves'' the pain she inflicts on her targets.
* SlasherSmile: Whenever she's about to get in on some serious action (i.e, torture), she sports a wide grin with bared teeth.
* TheSociopath: Capella is extraordinarily cruel and has no quarter for mercy or compassion. Subverted in ''Decode'', where she mellows out and comes to genuinely like Irma.
* {{Stripperific}}: Like other female Ixorian agents, her bio suit is this, but its ''Decode'' design in particular leaves absolutely ''nothing'' to the imagination.
* SuperStrength: Capella is an Ixorian Altan, meaning she is just as powerful as Birdy.
* TheThingThatWouldNotLeave: Like Kidel, she uses a legal technicality to use Tsutomu's house as shelter late into the story. Unlike him, her presence deeply disturb Birdy and Tsutomu.
* TooDumbToLive: Downplayed. She knows Birdy's ByTheBookCop nature means she wouldn't try anything, but Capella during her stay at Tsutomu's home needlessly antagonizes her at every turn, up to bragging about murder. As Birdy later demonstrates, she could easily kill her in her sleep, and had it been someone less kind, they would have likely done it.
* TokenEvilTeammate: Of all the Federation agents sent to Earth, Capella is by far the most malicious and poses a genuine threat to national security.
* TortureTechnician: Regardless of whether she gets any results, Capella is a creative torturer, making the most macabre displays of her victims to demoralize other criminals. She's also skilled in MindRape, as evident by her mental interrogation of one criminal.
* WhamLine: This chilling exchange:
-->'''Birdy:''' [[spoiler: No, I don't think Revi was behind Akrabar. There are key witnesses to testify.]]
-->'''Capella:''' [[spoiler: Hmmm. Since there are no mice around, let me tell you something good...]]
-->'''Capella:''' [[spoiler: '''THAT WAS ME. I DID IT.''']]
* WouldHurtAChild: While it's unknown if she knows or cares if he is one, she attempts to kill Chigira, mainly viewing the threat he poses to others in his monstrous state.
!!!Post-timeskip
After fully recovering from her injuries, Capella steadily makes recurring appearances in ''Evolution'', regularly butting in on the diplomatic discussions of the Ministry of Foreign Affairs. Capella's true allegiances are revealed to be with the Federal Army, still scheming to take after Neith's failures and launch a violent invasion of Earth to place it under Federation control. As a result of her actions in mobilizing a military conflict and her allegiances, as well as a pivotal role in the Akrabar disaster[[note]] a disastrous terror attack that left over two million dead and is at the center of a mystery regarding Revi being framed or not[[/note]], she is ultimately revealed to be one of the main antagonists of the overall manga saga.

----
* AssholeVictim: [[spoiler: While she was thoroughly provoked into acting out of line for a propaganda piece, it's hard to feel bad for her knowing she is a vicious war criminal and TortureTechnician herself.]]
* AxCrazy: Derives intense borderline ''sexual'' pleasure from the suffering of others, as demonstrated by her abuse of poor Kred.
* BackForTheDead: [[spoiler: Makes a brief but significant reappearance after the time skip, where it's shown the JSDF caught and interrogated her. After killing one of her captors, she is shot down.]]
* ColdBloodedTorture: Her favorite hobby. As the observing sailors note, she doesn't care about getting information as much as she gets her kicks from the interrogation process.
* DirtyCoward: When facing arrest from Birdy for her crimes, she aims for Tsutomu's friends with incendiary ammunition to distract her. Before making her escape, Neith also opts to destroy the entire ship to prevent pursuit, killing everyone on board except Birdy, Nechla, and Tsutomu's friends.
* LaserGuidedKarma: Neith, who gets her kicks off torture, and was specifically torturing Kred and his friends in an illegal interrogation pre-time skip, [[spoiler: appears after the time skip brutalized in an unethical interrogation.]]
* KarmicDeath: [[spoiler: It doesn't get much more karmic for a war criminal infamous for torture to die an unceromonious death after being tortured herself.]]
* LackOfEmpathy: When the crewmen of the ship plead with Neith to not leave them behind as she's making her escape, she furiously states they all deserve to die with Birdy for being unable to control the situation.
* NakedOnArrival: When she arrives on Earth. She steals some clothes not long after.
* SmallRoleBigImpact: [[spoiler: Has precious minimal screentime in after the timeskip, but her death is the catalyst Capella uses to justify the Federation's invasion of Earth.]]
* SociopathicSoldier: Neith is infamous for the widespread torture of prisoners of war during her days as a soldier.
* VillainExitStageLeft: Realizing she has no chance in combat against Birdy, she opts to destroy the ship they're stationed on, raids the armory, then flees for parts unknown. She is marked as a dangerous fugitive by the Federation not long after.

->'''Voiced by:''' Creator/YasuhiroMamiya (Japanese), Creator/ChrisAyres (English)
[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/bacillus.jpg]][[caption-width-right:300:[[labelnote: As Goro Nagase.]]https://static.tvtropes.org/pmwiki/pub/images/geega.PNG]] [[/labelnote]]
A highly wanted parasitic, slime-like alien criminal. In all iterations of the story, he steps up to take down Birdy Cephon after Geega's defeat but is quickly defeated. He has a slightly more expanded role and character in the rebooted manga.
----
* AdaptationalBadass: He is a far more tenacious foe to Birdy in the remake manga, surviving multiple encounters and serving as a recurring threat.
* AdaptationalDistillation: In ''Birdy the Mighty II'', one of the earliest arcs features Bacillus as an ArcVillain and centers on his gradual descent into total insanity. In ''Decode,'' he is simply introduced the way he is by the end of that arc with no buildup.
* AdaptationalIntelligence: Bacillus is a far more cunning character in the remake manga than he is in any other continuity. Even in his descent to further insanity, he is capable of planning and keeping a loose grip of his mind, something his ''Decode'' incarnation doesn't have the ability to do.
* AdaptationalVillainy: Although Bacillus is largely the same bad guy in every continuity, he has a considerably higher on-screen body count in the remake manga. Coupled with his greater intelligence and higher capacity for premeditated cruelty, it makes this incarnation of Bacillus the most malignant of them all.
* AxCrazy: Birdy and Revi surmise that Bacillus grows more insane with each body he takes, his psyche simply being unable to handle the overflow of memories. He eventually completely loses it.
* AxesAtSchool: Eventually, Bacillus simply decides to walk up to Tsutomu's school with a revolver on hand under the guise of Goro, indiscriminately shooting up enough people hoping to draw Birdy out.
* AliensAreBastards: He's a slime-like alien that assimilates other lifeforms.
* AppendageAssimilation: All slime monsters can do this. He even does it to Geega in ''Decode.''
* AssholeVictim: He is abruptly incinerated by either Gomez or Salamander at the height of the carnage he causes at Tsutomu's school.
%% Doesn't explain what the reaction is. * BerserkButton: His ''own name'' becomes this when he begins to lose his sense of self from taking over too many organisms.
* {{Blackmail}}: He threatens to murder Gomez's wife and daughter if he doesn't comply with helping him locate Birdy.
* BlobMonster: Bacillus is a green slime monster that can assimilate any living creature, including dogs, people, and in ''Decode'', Geega.
* BodyHorror: Bacillus is an oozing parasite that bonds and kills the host, then moves on to another. In the OVA, he bonds himself to several dogs at once before getting repelled by dish soap, then bonds himself to some Arkazoids that Birdy took out seconds earlier. In Decode, his then-current host falls apart, then moved to Geega, who also falls apart as his flesh seems to be literally melting.
* CombatTentacles: Bacillus uses these in fighting Birdy.
* CopKiller: He murders detective Goro Nagase for his body. Later, when Goro's team suspects he's acting strangely, Bacillus butchers them all on the spot.
* DiesDifferentlyInAdaptation: In the original and rebooted manga, he is incinerated to death by either Gomez or Salamander when he goes out of control. In the OVA and ''Decode,'' he is killed by Birdy.
* FaceStealer: He takes a form by consuming the host.
* {{Flanderization}}: He's always batshit insane in every depiction, but even in continuities besides the remake manga, Bacillus demonstrates a little cunning. In ''Decode,'' he is introduced as already completely insane and is almost animalistic in nature.
* HumanDisguise: He settles for a human form after cycling through animals, killing detective Goro Nagase for his body. Although considering Bacillus is behind a string of mysterious human deaths in the suburbs, Goro isn't the first victim.
* ItsAllAboutMe: Gomez describes Bacillus as an intensely selfish individual that puts his own interests above everything else.
* KnightOfCerebus: The point in which Bacillus shows up in every continuity after Geega always marks a more serious turn of events considering the greater threat he poses. However, he truly takes this up in the {{Seinen}} reboot, being the first villain to demonstrate how darker the manga is by gruesomely murdering innocents on-screen and stirring mass panic.
* MoralMyopia: As he's dying, he curses Gomez in complete disbelief of how he could "betray" him. Not too long ago, Bacillus threatened to murder his family and betrayed Revi. Granted, he ''is'' completely insane by this point...
* LogicalWeakness: He is a mucus-like parasite. Fire kills him instantly.
* PossessionBurnout: Bacillus's possession causes the body to decay, forcing him to find another host. Although Revi was working on an artificial body for him, he goes off the deep end in wanting Birdy's body instead.
* SmallRoleBigImpact: While Bacillus really doesn't accomplish much of anything, his atrocities set most of ''Birdy the Mighty II's'' plot in motion by injuring Chigira and him subsequently being transferred over to [[MadScientist Hikawa's]] hospital. Also, his actions [[spoiler: set the police and Natsumi on leads of discovering Tsutomu's condition and ties to Birdy]] ''very'' late into the story
* YouHaveOutlivedYourUsefulness: Gomez and Revi conclude Bacillus is no longer possible to control after he threatens the former. Salamander is dispatched to kill him.
* VillainousBreakdown: He completely loses what's left of his mind when Salamandel sets him on fire, repeatedly screaming Gomez's name in impotent fury.
* WouldHurtAChild: He tries to take over Natsumi in his first fight with Birdy as a mere slime, almost succeeding. Later on, he starts shooting up Tsutomu's school, only keeping it restrained to save enough bullets for his confrontation with Birdy.

An alien smuggler currently working on Earth. In every iteration of the story, the plot kickstarts with Birdy Cephon in hot pursuit of him.
----
* AdaptationalBadass: In the original manga, he had no fighting ability whatsoever. In every version since he demonstrates enough ability to defend himself competently. However, most notably, he is by far the most badass in ''Decode'', being biologically enhanced enough to fight on even footing with Birdy.
* BladeBelowTheShoulder: He sports one of these in ''Decode'', enhanced to penetrate Birdy's bio armor.
* DeathByAdaptation: He is captured by Birdy in the original manga and OVA. He dies one way or another in every other continuity.
* DiesDifferentlyInAdaptation: In ''Birdy the Mighty II'', he is assassinated by Salamander when cornered by Birdy. In ''Decode'', Bacillus devours him when he completely loses his sanity.
* HeKnowsTooMuch: In the rebooted manga, Gomez has Geega assassinated when he faces imminent capture by Birdy.
* SmallRoleBigImpact: He never lasts long, but he's the reason Birdy accidentally kills Tsutomu. What he smuggles into earth based on the continuity (Spirits, the Ryunka) also enable the major antagonist's plans.
* StarterVillain: He is always one of the first two characters introduced next to Birdy.

The Arita Family is famous for more than the quality of their hot springs. An UrbanLegend circling around the family is their ancestors slew an {{Oni}}, and the Aritas monetize this myth by displaying trinkets belonging to the Oni. In truth, the Oni is in fact a biological RobotSoldier the Arita royalty brought with them fleeing Alta. While the old guard tried to power it up, they failed and left it to rot under where the modern Arita inn is built today. When some sensationalist TV reporters sneak around the inn, they accidentally discover it [[TooDumbToLive and have the great idea to fiddle with it until it springs to life.]]
----
* AIIsACrapshoot: Despite its biological body, it is by all accounts a robot in Altan terms. Having long lost its purpose and having no directives, all it can do now is destroy everything around it.
* AttackItsWeakPoint: Its artificial heart is its only weak point.
* CurbStompBattle: [[spoiler: When it reappears to fight Gnome for Undine, it completely decimates the Marionette.]]
* ItCanThink: To a degree. While it is for the most part a mindless engine of destruction, it can adapt to combat tactics. When Birdy fends it off the first time, it seeks out its armory (the Arita "trinkets") before re-engaging her.
* PostFinalBoss: The epitome of this. It is the last major foe Birdy faces in the first half of the remake manga. While it is very tough and strong, it is not as tough as Hikawa, and its plot relevance is ultimately very minimal.
* ReforgedIntoAMinion: [[spoiler: It makes a surprising reappearance in ''Evolution'' as Agata's reforged bodyguard, armor and all. It proceeds to lay a can of ass-kicking on Gnome.]]

A notorious galactic terrorist, whose claim to infamy comes from previously razing the planet of Eon. Hower originally debuted in the one-shot special ''King of the Labyrinth'', which was created to celebrate the release of the OVA. His story was repurposed into an episode of ''Decode'' and he also appears in ''Evolution'', already imprisoned, illustrating the events of the other continuities can be taken as BroadStrokes to the rebooted manga's timeline.
----
* AdaptationalDumbass: In ''Decode'', Skelezzo describes him as a psuedo-intellectual, and he fittingly demonstrates to be a SmugSnake that thinks he's smarter than he really is. In the manga, he is a Hannibal Lecter-like criminal that Megius consults for advice.
* ColonyDrop: His plan is to drop an inactive satellite right on top of the Sanctum Sanctorum.
* ImAHumanitarian: He ''cannibalized'' his victims on Eon, which is where his title comes from.
* InsufferableGenius: Kinzel loves to brag about his intelligence and college degrees.

->'''Voiced by:''' Osamu Ichikawa (Japanese), Creator/TedLewis (English)
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/hik_s.PNG]]
The BigBad of the OVA series. Seichiro is an insane biologist affiliated with the alien Christella Revi to fulfill his militaristic ambitions. Much of his character was salvaged and greatly expanded upon as the character Shogo Hikawa in the rebooted manga. However, Seichiro still exists in that continuity as the late grandfather of Shogo. [[spoiler: It's revealed late into ''Birdy the Mighty II'' that "Shogo" Hikawa is in fact Seichiro using an alias, meaning the character was fully imported.]]
----
* AdaptedOut: Unlike the remake manga, ''Decode'' does not feature the character of Seichiro Hikawa even under a different name. He is instead replaced by Satyajit Shyamalan, who is a considerably different character despite filling in for Hikawa.
* AxCrazy: He is evidently insane, but it is truly cemented when he tries to annihilate all of Japan even knowing subconsciously his plan is doomed to fail.
* BreathWeapon: After he's mutated, he is capable of launching a psychic laser from his mouth.
* CanonImmigrant: Sort of. He was created for the OVA and while he never appeared in the original manga, he was imported when the remake manga began -- as [[DecompositeCharacter two different people (albeit as grandfather and grandson)]]. [[spoiler: [[TheReveal Or so it seems.]]]]
* ClippedWingAngel: He bulks himself up when facing Birdy, being more than a match for her afterward. Not long into the fight, however, [[BodyHorror his body literally falls apart]] and he's reduced to a shriveled mutant with moderately improved psychic powers.
* FantasticRacism: He openly views Azkazoids (Marionettes in ''Decode'' and the remake manga) with contempt, and he even disparages the death and nature of Undine in front of Salamander -- her brother.
* MindOverMatter: One of the abilities his experiments granted his subjects (as mentioned below himself included) was telekinesis.
* ANaziByAnyOtherName: His backstory, motives, and character draw disturbing parallels with the real Unit 731 and [[NoCelebritiesWereHarmed Shirō Ishii.]]
* OlderThanTheyLook: His experiments on himself have physically de-aged him back to his prime. After his death fighting Birdy, his corpse reverts to its true age.
* ProfessorGuineaPig: One of his test subjects after hooking up with Revi was himself, giving him restored youth, superhuman strength, and telekinesis. It also starts to deform him after a while.
* SingleTear: We see him shed one of these in a flashback to when Revi met him.
* SmugSnake: He acts like he's better than he is in front of others when subconsciously he knows his research is flawed.
* SuperSoldier: His initial experiments in the Imperial Army were to this end, as are his experiments for Revi.
* SuperStrength: Not only was he able to go toe-to-toe with Birdy, he at one point chucks her into a wall like a ragdoll.

A parasitic alien bioweapon that Geega smuggled into Earth for Shyalaman. It is at the center of his twisted plan to exterminate most of the human race.
----
* DemonicPossession: It requires a compatible host before it can unleash its power.
* EldritchAbomination: The Ryunka's ''incomplete state'' is a four-legged monstrosity protruding what appears to be human arms in its underbelly.
* LiterallyShatteredLives: It glasses anyone and anything unfortunate enough to be within its radius.
* OmnicidalManiac: Desires to obliterate the universe at large so it can attain the peace of "absolute silence."
* PunyEarthlings: Ridicules the foolishness of Shyamalan and people like him that came before, stating it cannot understand the stupidity of those seeking to harness its power to destroy others.
* VoiceOfTheLegion: When it has full control over Sayaka, its voice manifests as this.

[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/450px_lullabyofobedience_lckc_en_scr_1e_5.png]]
Sayaka's grandfather. A rich neuroscientist whose research is abused by affiliate Shyamalan under his nose.
----
* CompositeCharacter: His role as Sayaka's caretaker parallels that of Agata Juuzou in ''Evolution.'' On the other hand, his affiliation with Shyamalan is that of her father's. He takes another cue from Juuzou in that he is oblivious to Shyamalan's illicit activities.
* CruelAndUnusualDeath: [[spoiler: Shyamalan strangled him to death in such a brutal way his fingerprints are left deeply imprinted in Katsutoshi's neck, and his expression of pure horror indicates it was evidently a horrible way to go.]]
* HonestCorporateExecutive: He is outraged when he discovers what Shyamalan has done with his work, to which he rebukes by calling him an idiot who only stifled scientific progress.
* PapaWolf: [[spoiler: He is determined to protect Sayaka from Shyamalan when the latter voices his intentions to his face. Unfortunately, he evidently didn't put up much of a fight being murdered.]]
* YoureInsane: When Shyamalan expresses his philosophy and intentions to Katsutoshi, he deems him ''completely'' insane.

->'''Voiced by:''' Creator/AyakoKawasumi (Japanese), Creator/MaxeyWhitehead (English)
[[quoteright:330:https://static.tvtropes.org/pmwiki/pub/images/01_531.jpg]]
A young girl whose legs are recovering. She is very fond of Nataru and tends to be hostile towards Birdy because she thinks Birdy's trying to 'steal' him from her. She had also lost her older brother in the Ryunka incident.
----
* BrattyHalfPint: Towards Birdy, she acts like a complete brat, causing her no shortage of trouble when she runs around the city in response to her "taking" Nataru from her.
* CurtainsMatchTheWindow: Brown hair and eyes.
* DarkAndTroubledPast: Her parents and brother were all casualties of the Ryunka disaster, effectively leaving her orphaned until her grandfather takes her in.

->'''Voiced by:''' Creator/MasayaMatsukaze (Japanese), Creator/EricVale (English)
[[quoteright:263:https://static.tvtropes.org/pmwiki/pub/images/jclkait.jpg]][[caption-width-right:263:[[labelnote: Click to see him mutated]]https://static.tvtropes.org/pmwiki/pub/images/nataru_2.PNG]][[/labelnote]]
An Altan refugee on Earth, who works as a nurse and a caretaker for orphaned children following the Ryunka disaster. He is also childhood friends with Birdy and the two have feelings for one another. Unknown to Birdy or his colleagues, however, Nataru hides some very dark secrets under his friendly visage.
----
* AxCrazy: Despite barely holding it together with an outwardly friendly demeanor, Nataru is a contender for one of the most insane characters in the franchise. He is a deranged SerialKiller utterly consumed by sorrow and does not hesitate to inflict extreme brutality on ''anyone'' he feels has slighted him.
* BigBad: Of Decode 02.
* CainAndAbel: The Abel to Valic's Cain, as the latter almost murdered him out of spite as kids. Ironically, reversed as adults, where Nataru is hellbent on murdering Valic while he wants nothing to do with him.
* ChildhoodFriendRomance: Nataru has this with Birdy, but they keep it low key due to their occupations. By the show's end, she fully reciprocates.
* ColdBloodedTorture: He inflicts the most heinous torture imaginable on his targets, reasoning they must suffer for what they caused with the Ryunka.
* DeathSeeker: He fully intends to die during or after his revenge-fueled rampage.
* DeadlyNoseBleed: [[EyeScream As well as bleeding from his eyes,]] when he begins to overuse his Ixorian powers.
* FaceOfAnAngelMindOfADemon: His boyish face and genial demeanor hide a bloodthirsty monster defined by rage.
* FreudianExcuse: As an Altan child, he suffered intense persecution from the populace, exacerbated by his adoptive father's occupation as a hardline Anti-Federation terrorist. His adoptive brother, Valic, resented him for taking away his father's attention and regularly physically and emotionally abused him. Nataru was later caught up in the Central Tower Attacks, witnessing the horror of war firsthand as a kid. After migrating to Earth and living a relatively normal life, his best friend is glassed in front of him in the Ryunka disaster, making Nataru fully believe he can never escape his cursed life.
* FriendToAllChildren: And harming them is among the fastest ways to set him off.
* GeneticEngineeringIsTheNewNuke: Nataru is an Ixorian, but he descended from a failed line of supersoldiers experimented with reality warping powers, making him a defective Ixorian.
* HairTriggerTemper: While Nataru can keep a decent lid on it, he is frighteningly easy to piss off and very irritable.
* HappilyAdopted: For the most part. Though his adoptive father's former involvement in terrorist activities created tensions, Nataru loved Dusk, and his murder is what fully sends him over the edge.
* IAmAMonster: How he feels about himself, and by extension, other Ixorians.
* IncurableCoughOfDeath: Another result of his terminal illness and overusing pain killers.
* KickTheDog: His horrific murders of siblings Faroid and Tesera is treated as crossing a line in-universe and out, as they expressed regret and no longer wanted anything to do with their terrorist cell.
* PinkGirlBlueBoy: When Birdy and Nataru are together, starting back when they were kids, Birdy is usually shown wearing pink and Nataru, blue.
* PowerDyesYourHair: Nataru's hair turn white when he activates his powers.
* RealityWarper: He has the ability to erratically phase in and out of reality or time and space itself.
* RedEyesTakeWarning: His eyes become permanently bloodshot after using his powers too much, marking the point where he is inevitably going to die from terminal illness.
* RoaringRampageOfRevenge: Once he finds out the aliens responsible for the Ryunka disaster are hiding on Earth, he embarks on an insane quest of revenge against his father's wishes.
* {{Sadist}}: Relishes in the agony of his victims as he tears them apart limb from limb.
* ScreamingWarrior: He's constantly shrieking in a bestial rage when he fights Moss and Birdy in the climax.
* SerialKiller: A borderline case, as he systematically hunts down every named agent in the military cell involved with the Ryunka disaster.
* {{Teleportation}}: One of his abilities as a RealityWarper.
* UnskilledButStrong: It's made clear Nataru has little grasp on actually handling his powers, but they're strong enough to where it doesn't matter.
* UsedToBeASweetKid: It's hard to believe the vicious maniac now used to be such a meek and sweet kid.

->'''Voiced by:''' Creator/TakayukiSugo (Japanese), Creator/KentWilliams (English)
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/chara_img07.jpg]]
Nataru's adoptive parent and Valic's biological father. Formerly the leader of an Altan uprising against the Federation, he's since taken to hiding on Earth, though some of his ambitions remain.
----
* AntiVillain: He may be a criminal and ex-terrorist, but he never harbored any ill will and was well-intentioned in that he was fighting for his people.
* EveryoneHasStandards: In the past, he turned down an offer to join Christella Revi, citing her as too extreme even for him. This put him at odds with his son and other resistance fighters.
* EyesAlwaysShut: He is never seen with his eyes open.
* GoodParents: To Nataru, as he wanted him to live a happy life away from his upbringing. He is very disappointed when he takes up the path of revenge, but doesn't stop him and understands his anguish. Dusk tried to be this for Valic, but Valic's preference for violence and envy for Nataru irrevocably ruined their relationship.
* RetiredMonster: He was once renowned for his vicious effectiveness as a guerilla fighter, but he's since stepped down and poses as an unassuming librarian.
* TheWorfEffect: Despite his fame, he is easily murdered by Gatol without any fight.

[[folder:The Insurgents]]
!!The Insurgents
->'''Voiced by:''' Gatol: Creator/AtsushiOno (Japanese), Mark Stoddard (English), Moss: Creator/YukoKaida (Japanese), Creator/LydiaMackay (English), Valic: Creator/ShintaroAsanuma (Japanese), Creator/ChrisPatton (English), Faroid: Creator/KoukiMiyata (Japanese) Creator/ColleenClinkenBeard (English), Tesera: Creator/RyokoShiraishi (Japanese), Creator/MonicaRial (English)
A cell of the Federation Army that was involved with smuggling and experimenting on the Ryunka on Earth, ostensibly to better combat the Alliance. After the Ryunka disaster, most of them were arrested but subsequently freed by Moss and Gatol. Regrouping on Earth, their plans on restructuring come to an abrupt pause when they are individually hunted down by a mysterious SerialKiller.
----
* AlasPoorVillain: Tesera and Faroid die literally crying and pleading for their lives, and of the group, were undoubtedly the least heinous.
* AssholeVictim:
** Rianshl and Agrazume were smug, racist assholes completely unrepentant over their role in the Ryunka disaster and murdering thousands. Their deaths, while brutal and horrific, are arguably deserved.
** Gatol murdered Dusk over simply not cooperating and procured a nuke for further destruction on Earth. There's no sympathy to be had when Moss betrays and murders him.
* CainAndAbel: Valic to Nataru in their childhood. Ironically, reversed given that Valic is fearing for his life as Nataru is hunting him down for nothing he personally did to him.
* CruelAndUnusualDeath: Any of them caught by Nataru is subject to this, being deliberately torn apart limb from limb before being smashed into paste.
* DirtyCoward: What Gatol claims of Tesera when she severs all contact and goes into hiding, although she is very justified in fearing for her life.
* DwindlingParty: As they are individually hunted down by Nataru. As morale drops, some members go their separate ways.
* EvenEvilHasLovedOnes: Tesera deeply mourns Faroid's passing.
* EvenEvilHasStandards: After Rianshl is murdered, all of them are extremely disturbed and often left speechless by the brutality of whatever is hunting them down.
* EyeScream: Nataru gouges one of Gatol's eyes out in his brutal fight with him.
* NoBodyLeftBehind: To cover their tracks, they are implanted with chips that disintegrate their bodies should they perish.
* LargeAndInCharge: Gatol, the leader of the group, towers over everyone else.
* ScrewThisImOuttaHere: Tesera cuts all contact with the group and tries to live a normal life in hiding on Earth. It doesn't last long before Nataru finds her...
* WeHardlyKnewYe: Rianshl, Agrazume, and Faroid are quickly killed off before establishing much personality.
----
!!Moss
[[quoteright:330:https://static.tvtropes.org/pmwiki/pub/images/chara_img12.jpg]]
Gatol's right-hand woman and the most recurring adversary of the group.
----
* AdaptationalBadass: Neith of the manga wasn't much of a fighter. When faced with Birdy for her crimes, she opted to flee. Later on, she was detained by human forces (albeit, the JSDF) while hiding on Earth. Moss, by comparison, is such a fierce fighter she outright defeats Birdy in single-combat and holds her own against a fully crazed Nataru.
* AttemptedRape: Some idiotic humans attempt this on Moss when she's alone. Although Gatol scares them off with a glare when he arrives, they're very lucky they got off that easily.
* BloodKnight: She lives for the thrill of combat, and it's taken literally on one occasion she forgoes her human disguise to maul at necks.
* CombatSadomasochist: Tells Nataru to come with everything he has in their final battle and relishes in every aspect of it, regardless of her being pummeled.
* DarkActionGirl: By far one of the most badass women in the franchise, going toe to toe with Ixorians despite not being artificially empowered in any way.
* TheDragon: Directly answers to Gatol and holds a level of authority over others in the group.
* {{Expy}}: Moss is a direct stand-in for Neith Washgam from the manga, being of the same species and having the same role as a military maverick conspiring to illicitly increase their influence on Federation politics.
* InLoveWithYourCarnage: Grows out of her disgust for his actions and instead becomes enamored with Nataru's brutality and strength.
* TakingYouWithMe: Albeit, somewhat half-heartedly, she sets off the nukes she stole after losing to Nataru, hoping to take him and Birdy with her.
* TheLastDance: After being rejected by Revi despite killing Gatol as requested, Moss decides her life no longer has meaning and she will end it in one last glorious battle with Nataru.
* WomenPreferStrongMen: She literally says this when betraying and murdering Gatol, saying he has grown too old and weak.

* ArcherArchetype: Momiji was already a skilled archer before inheriting alien weaponry, and the new high-tech bow does nothing to slow her down.

* KickTheSonOfABitch: [[spoiler: Once his patience with Hikawa runs out, he puts out an arrest warrant and seizes all his assets. In the fallout of Ondine and Birdy's battle at his underwater facility, Hikawa is reduced to a street bum with nothing to his name.]]

* RidiculouslyHumanRobots: Despite being a Marionette and even claiming she exists solely to protect Birdy, Violin is so empathetic and independent [[WhatMeasureIsANonHuman it calls into question how much of a robot she really is.]]

* SelfServingMemory: A rather tragic example in ''Decode'' with Birdy's memories of [[spoiler:Violet painting her as more human in behavior than she actually was in reality]].

* EvilIsPetty: He does everything in his power to torment Shigenobu without killing him, simply because he has favor with Mido even in his demented state. From killing his troops to intentionally causing civilian disasters just so he's forced to clean up after him or suffer political consequences. [[SurprisinglyRealisticOutcome Unfortunately,]] this backfires ''big-time'' for Hikawa when Shigenobu decides Hikawa [[TheDogBitesBack is no longer worth the hassle of keeping around]] and cuts his funding entirely.

* HumanoidAbomination: [[spoiler:As an Ixorian, she has a default humanoid form but is capable of turning into an energy-based {{kaiju}} when pushed far enough]].

* SpellMyNameWithAnS: Birdy Cephon Altirra/Altera/Altaria

* SmallRoleBigImpact: While Bacillus really doesn't accomplish much of anything, his atrocities set most of ''Birdy the Mighty II's'' plot in motion by injuring Chigira and him subsequently being transferred over to [[MadScientist Hikawa's]] hospital. Also, his actions [[spoiler: set the police and Natsumi on leads of discovering Tsutomu's condition and ties to Birdy]] ''very'' late into the story.
* SpellMyNameWithAnS: Bachilus/Botulus/Bacillus

* ForWantOfANail: Ironically, had Kinzel succeeded in his plans, the galaxy would have found peace and freedom.

* KickTheSonOfABitch: Downplayed. While Rianshl and Agrazume were racist, unrepentant assholes, the way Nataru brutally murders them even as they beg for their lives is conveyed to make Nataru the worse of them by far.

* BoobsOfSteel: Birdy is incredibly buxom and possesses colossal alien physical strength.

* {{Bishonen}}: His human disguise is a pretty-faced blonde boy. Even in his normal state, he has a very bishie face despite being a dog-like alien.

* FourElementEnsemble: [[ReligiousAndMythologicalThemeNaming Befitting their names,]] each of the four have a specific power:
** Salamander [[PlayingWithFire manipulates fire.]]
** Slyph controls wind, [[RazorWind often manifesting as blades.]]
** [[DishingOutDirt Gnome]] possesses [[SuperStrength unimaginable strength]] on par with that of Ixorians.
** Undine [[KillItWithWater controls water]] and is nearly unstoppable in an aquatic environment.

* AmbiguouslyBrown: His name and appearance would suggest that he's ethnically southern Indian or more specifically Malayalam.

* ADateWithRosiePalms: Subverted in a way that's played tragically. Late into ''Birdy the Mighty II'', Tsutomu contemplates masturbating as Birdy is asleep but stops himself realizing that it's not even his body, let alone how Birdy would easily notice and react to what he's doing. He then slumps into depressive contemplation over his circumstances, recognizing he has no genuine freedom or privacy in his current state.

* ADateWithRosiePalms: Due to Hikawa's experiments on him, he initially cannot control his monstrously increased libido and fantasizes over Birdy while masturbating to her. He immediately expresses fear of what he's becoming after the deed.

* OneHundredPercentAdorationRating: [[spoiler: During her brief term in the Ministry of Science, Revi was viewed as a paragon among the Altan people.]]

->'''Voiced by:''' Creator/AkioOhtsuka (Japanese, OVA), Cory Carthew (English, OVA), Creator/UnshoIshizuka (Japanese, ''Decode''), Creator/NewtonPittman (English, ''Decode'')

* BathKick: Birdy does this in the first episode of the second season of ''Decode''.

* WeaponOfChoice: Needles carved from her bio armor capable of penetrating through the bio armor of other living organisms. Although obviously fatal should she aim for a vital or the head, they induce paralysis or sleep upon hitting non-vitals.
