!Protagonists
!!The Ouroboros

[[folder:In General]]
* ActionGirl: Mio, Eunie, and Sena are young women who are capable, experienced soldiers and aren't afraid to get into a fight (and in Eunie's case quite enjoys sparring).
* ChildhoodFriends: Noah, Lanz, and Eunie are friends that have known each other since childhood.
* ColorCodedForYourConvenience: Their Ouroboros forms differ in color depending on who's "controlling" the body. The Keves' crew Ouroboros forms are dark purple in color, whereas the Agnus crew's forms are white.
* CriticalAnnoyance: If the heroes remain in their fused state for too long, their bodies will start to heat up and warning sounds start blaring. While the group has no idea what the sound is, Taion theorizes it cannot be anything good. It is not until their encounter with Consuls O and P they learn what the warning sound is. [[spoiler:True to Taion's concerns, the warning sounds signal the Ouroboros are dangerously close to becoming the trigger for an Annihilation Event.]]
* ElitesAreMoreGlamorous: Prior to becoming Ouroboros the party were all part of their Colonies elite special forces.
* EnemyMine: The two halves of the party are forced to put their differences aside after trying to kill each other almost immediately beforehand to fight against D.
* FireForgedFriends: Despite some initial difficulties, they become close friends through their experiences together.
* FiveTokenBand: In addition to the nations of Keves and Agnus themselves being mixes of races from ''Xenoblade Chronicles 1'' and ''Xenoblade Chronicles 2'' respectively, Noah (Homs), Eunie (High Entia), Lanz (Machina), Mio (Gormotti), Taion (Human), and Sena (Blade) are all different races.
* FusionDance: Noah and Mio, Eunie and Taion, and Lanz and Sena can combine via Interlink to form an Ouroboros, its form depending on who is the dominant partner at the time. While one form, they do still keep their separate minds, with the one currently speaking being signified by either the right (Keves) or left (Agnus) eye flashing while they talk.
* GenderEqualEnsemble: Three boys (Noah, Lanz, and Taion) and three girls (Mio, Sena, and Eunie) in the main party.
* GhostMemory: When the party fuses into their Ouroboros forms, they see the memories of their partner before the fusion completes.
* GoodCounterpart:
** As Ouroboros want to end the vicious cycle of death and rebirth comprising the ForeverWar, they are this to Moebius, who want to maintain the status quo to preserve themselves and entertain themselves with the neverending war between Keves and Agnus.
** Moreso for Noah and Mio towards [[spoiler:N and M, respectively, as the current Noah and Mio are considered to be the incarnated hopes and repentance of the previous Noah and Mio once they became Moebius. Though somewhat downplayed for M as she was GoodAllAlong and that thanks to her [[SpannerInTheWorks swapping bodies with the current Mio prior to her Homecoming]], she gave Ouroboros a chance to fully fight back]].
* HealingFactor: As long as the core of an Interlink remains intact, they can easily heal from otherwise mortal wounds. In-gameplay this is represented in their inability to take damage while fused.
* HelmetsAreHardlyHeroic:
** The Keves squad is introduced helmetless when almost everyone else is wearing one.
** While the Agnus squad is introduced wearing helmets, they break in the subsequent battle with Noah's squad and they don't bother wearing them again once both halves join forces.
* HeroicSacrifice: Attempted when Lanz and Sena try to stop N by [[spoiler:grabbing him and launching themselves in Interlink form into the air in an attempt to destroy them with the inevitable overclocking explosion from staying Interlinked for too long, only to be foiled by X.]]
* HourOfPower: They can only stay Interlinked for so long until they heat up so much that they're forced to break up and have to wait longer before fusing again.
* IdiotBall: Despite [[spoiler:Shania]] mentioning it to be her plan more than once, the party and Ghondor are still blindsided by [[spoiler:Shania coming back from killing herself as Moebius S, though to be fair, this only happens in an optional sidequest.]]
* ImpliedLoveInterest: While Noah and Mio are the only OfficialCouple among the main cast, the others are sorted into M/F duos in a version of EveryoneMustBePaired, although it's downplayed in that none of them are confirmed as overtly romantic to nearly the same extent.
** Eunie and Taion are a WillTheyOrWontThey duo who receive a lot of ShipTease, but it's left ambiguous if they're romantically attracted or they're just a particularly {{Tsundere}} variant of PlatonicLifePartners. In particular, a lot of Eunie's insults to Taion can be interpreted as light LovingBully teasing that he's [[ObliviousToLove too dense to pick up on]], but since she's TheGadfly it's also possible she's acting flirty on purpose purely to annoy him. In the ending [[spoiler:Eunie tells Taion he's only her fourth favorite friend, flustering him, but in characteristic Eunie fashion even ''that'' is likely a form of trolling, and again it's ambiguous whether it's her way of flirting with him one last time or she genuinely sees them as JustFriends]].
** Lanz and Sena never show any overt signs of attraction to one another, with their relationship usually being depicted closer to a PlatonicLifePartners friendship between BirdsOfAFeather, being the first of the party to take a liking to one another and breaking the ice. At the same time, some of Sena's discussions on Interlinking and who is dominant are [[DoesThisRemindYouOfAnything worded in such a way]] that implies it to be akin to a RomanticFusion even if they aren't outwardly romantic.
** Despite starting off as strangers, Riku and Manana are always praising one another and doing things to keep each other happy, with Riku showing a great deal of concern over Manana's wellbeing after she attempts to defend the party from spiders. The ending [[spoiler:has them in tears over the prospect of being separated from one another]].
* ImmuneToMindControl: Due to their Ouroboros powers freeing them from the slavery of the Flame Clocks, the main party is immune from getting controlled by the Consuls. [[spoiler:However, they are still vulnerable to M's possession ability. However, since this ability allows her and Mio to swap bodies as part of M's gambit to save the party and be free of N, this turns out to be a good thing.]]
* InSpiteOfANail: [[spoiler:It's implied that no matter what happens in a given cycle, Noah and Mio will meet, abandon their nations, and get involved with the Lost Numbers.]]
* LetsYouAndHimFight: The first time the Keves and Agnus halves of the party meet, they fight and are pretty evenly matched until Vandham gets them to stop.
* MasculineGirlFeminineBoy: Eunie is a brash and aggressive [[TheLadette Ladette]] with {{Tsurime}} and little in the way of proper manners, while Taion is a somewhat feminine-looking bookworm with {{Tareme}} whose reserved demeanor is a cover for his emotional sensitivity and lack of confidence. Relatedly, Eunie tends to take the reins as the more dominant member of their Ouroboros fusion.
* NiceGuy: None of them are particularly unfriendly people; at worse, Lanz and Taion have a lot of understandable bad blood left over from the ForeverWar, but they warm up pretty quickly and even before then are more than willing to bury the hatchet for mutual survival.
* TeethClenchedTeamwork: Downplayed. Some members like Taion and Lanz aren't keen on fighting together at first given the bad blood between their countries, and they have some disagreements with how they fight. As time progresses, however, the group becomes a more cohesive unit.
* TrueCompanions: By the end of the game, the group has become this after all of the trials they've went through.
* TheUnchosenOne: Monica reveals this to be the case in Chapter 5. [[spoiler:The power of Ouroboros was meant to go to the City's candidates, all of whom trained for that explicit purpose. The Kevesi and Agnian groups became Ouroboros partly out of circumstance and Vandham's snap decision to activate the Ouroboros Stone.]]
* UniqueProtagonistAsset:
** As the Ouroboros, the party are ImmuneToMindControl, can uniquely change their classes and instantly learn their Arts--and as a result use both Keves and Agnus Arts at the same time--and finally Interlink to become substantially stronger.
** After Noah finally unsheathes Lucky Seven in Chapter 2, he gains a new Talent Art in the form of "Infinity Blade." It is also, for a long time in gameplay, the only time a party member can have a Talent Art different from their current class'.
** At the start of Chapter 6, [[spoiler:Noah and Mio obtain new Talent Arts. Noah's "Unlimited Sword" Talent Art allows him to fully use Lucky Seven in battle with a slew of new Arts that change depending on his current role as well as an additional new Talent Art, "Final Lucky Seven," which is its own Blade Combo. Mio, meanwhile, gains "Dominion Flower" as a Talent Art.]]
* WhatIsThisThingYouCallLove: Due to their upbringing as ChildSoldiers that come out of cradles, the party initially has some issues comprehending forms of love that aren't based around comradeship, such as familial and romantic love. Learning about the latter is implied to be how Noah and Mio come to realize their own feelings towards each other.
* WithAFriendAndAStranger: Amongst the Agnian trio, Mio and Sena had already known each other since their days in their old colony, but Taion is a relative newcomer to their group.

[[folder:Noah]]
!!Noah
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/xbc3_noah.png]]
[[caption-width-right:350:[[labelnote:Click here to see his Ouroboros form]]\\
https://static.tvtropes.org/pmwiki/pub/images/noah_6.png[[/labelnote]]]]
->'''Voiced by:''' Creator/RyoheiArai (Japanese), Harry [=McEntire=] (English), Gabriel Todesco-Bond (Child English)\\
'''Class:''' Swordfighter (base)\\
'''Role:''' Attacker (base)

->''"Fighting in order to live. And living to fight. That's the way of our world... Aionios."''

The "off-seer" of Colony 9's special forces from Keves and one of the two protagonists of the story.
----
* AbsurdlySharpBlade: The Lucky Seven, renamed by Noah as the Sword of the End. It's part of a series of swords and is capable of cutting through a Ferronis like a hot knife through butter. When Lanz attempted to strike it at Riku's behest, his Blade was the one getting cut in half. It's for this reason Noah keeps it sheathed inside his own Blade as a last resort. It's even capable of slicing through immaterial things such as [[spoiler:Moebius S's time fields. This is because it is made in part using metal from [[EldritchLocation Origin]].]]
* TheBard: As an off-seer, he was trained to play his flute to allow the souls of the departed to pass on to the beyond. He is also sometimes seen playing it at camp with Mio.
* BifurcatedWeapon: Within Noah's sword is a smaller and even sharper sword, the Sword of the End. In his Ouroboros form he wields a sword that can split down the middle into two identical swords, as well as being able to transform into wings or a surfboard.
* ContrastingSequelMainCharacter: To the protagonists of the previous games:
** Like Shulk in the first ''Xenoblade Chronicles'', Noah has military training owing to Keves' status as being perpetually locked in war. That said, Noah would rather not fight if possible and has the job of sending off the departed spirits of the dead. Shulk was willing to fight other Homs, but not outright kill them, and was more interested in tinkering with machinery. Regarding their relationship with the antagonists, Shulk grew to vehemently despise the Mechon after Fiora's "death" and their continued atrocities across Bionis while Noah never had any kind of hatred or resentment towards Agnus, even sending off their dead despite being an off-seer for Keves, [[spoiler:his resentment instead being reserved for Moebius]].
** Rex was a salvager who initially had a simplistic view of the world due to his young age and, by all accounts, got involved in ''Xenoblade Chronicles 2'' by accepting the right job at the wrong time. Noah has a more nuanced view of the world, having lived in a country that's been at war for who knows how long and raised as a ChildSoldier whose role in the story is sparked by the appearance of a previously unknown third faction attempting to get both sides to stop fighting.
* CoolSword: Noah's Veiled Blade and the sword he got from Riku during his trainee days.
* DoIReallySoundLikeThat: When Eunie mocks his sense of duty as an off-seer, he asks her if he sounds as deep as she implied to her annoyance.
* DueToTheDead: Believing in sending off soldiers after they die no matter what faction they're part of.
* ExoticEyeDesigns: [[spoiler:Much like with Mio upon gaining M's body, Noah's Iris gains the comibed Ouroboros and Moebius Ring once N merges with him following his HeelFaceTurn in Chapter 7]].
* {{Expy}}: Of Fei Fong Wong from ''VideoGame/{{Xenogears}}'', as they are both ponytailed pacifists that seek to end a destructive war by uncovering its enigmatic origins. Noah's [[FusionDance Ouroboros]] form is also based on Fei's [[HumongousMecha gear]] Weltall, and he shares a name with the protagonist of the prototype version of ''Xenogears'' that went on to become Fei.
* GiverOfLameNames: Noah considers himself this, which is why he couldn't come up with a new name for the Lucky Seven. The name he does come up with, Sword of the End, [[AvertedTrope is pretty cool]]. [[spoiler:This is a trait he shares with N, as one of his past selves asked Mio to name their son due to this trope.]]
* TheGlovesComeOff: While ironically for the trope title the rest of his Blade forms into a gauntlet around his left arm, Noah's attacks become a lot more powerful when he uses the Sword of the End comprising the hilt.
-->'''Noah:''' Sorry, but I can't go easy on you!
* GoodIsNotSoft: While he abhors all the fighting and war in Aionios, he knows that if he doesn't fight he and his friends will die. [[spoiler:And when O and P cause Ethel and Camuravi's deaths, he has no objections to killing them and refuses to send them off, a fate he usually wouldn't condemn anyone to (their crimes were arguably not any worse than K's, but as he puts it he's only human and his kindness has limits when it comes to personal offenses, in this case contributing to Ethel's death)]].
* HeroesPreferSwords: His default class is Swordfighter that uses a futuristic red sword, not unlike [[VideoGame/XenobladeChronicles1 the Monado Replica EX]] or [[VideoGame/XenobladeChronicles2 the Aegis]].
* HeroicBSOD: [[spoiler:When N defeats the party and imprisons them to make them watch as Mio's time dwindles, Noah takes it the hardest, beating his knuckles bloody trying to find any way to escape and when that fails, being so despondent that he refuses to eat. When N mockingly gives him his flute to send Mio off during her Homecoming, he is unable to find the strength. It takes M revealing herself to actually be Mio to get him out of his despair.]]
* {{Infinite}}: Noah has a Talent Art named "Infinity Blade" which bears the same name as the Level IV Special of [[VideoGame/XenobladeChronicles2 Pyra/Mythra]]'s ascended form.
* LongHairedPrettyBoy: He sports a prominent SamuraiPonytail unlike Shulk and Rex, has a slender build, and also has the soft features to match.
* MartialPacifist: Noah is one of the few people who seeks to stop the constant war Aionios is thrust into, though he's willing to fight others to achieve this end if necessary.
* MusclesAreMeaningless: His official bio describes him as being very powerful despite his slim build.
* MythologyGag: [[spoiler:When he unlocks the true power of the Sword of the End and uses his "Unlimited Sword" talent art, his new Arts are represented with kanji similar to Monado Arts.]]
* NiceGuy: Almost a series tradition now, Noah is generally a pleasant guy like previous protagonists Shulk and Rex.
* OurHeroIsDead: [[spoiler:After Mio dies and N executes Noah, he goes to an AfterlifeAntechamber where he is informed of N's true nature and whether Noah will make the same choice that he did. When Noah resolves to change the world instead of keeping it the same, it's revealed that M, who is actually Mio post FreakyFridayFlip, saved him at the last second. It is ambiguous as to whether Noah really died when N executed him, and he was given a second chance at life, or if he was having a YearInsideHourOutside experience in the second before the blade touches his neck.]]
* PrecisionFStrike: While he's normally got a clean mouth compared to the likes of Eunie, [[spoiler:he tells N that he's "full of shit" while fighting him during Chapter 6.]]
* RedIsHeroic: He's a main protoganist who wears a red jacket and wields a sword that is also predominantly red.
* SamuraiPonytail: Wears his long hair in a ponytail, and [[https://twitter.com/XenobladeJP/status/1493118827332538376 his official bio]] describes his way of holding his sword as very samurai-like.
* SecretTestOfCharacter: Undergoes one courtesy of [[spoiler:Mio using M's powers to project into his mind memories of his past lives and explanations of the changes he underwent due to them, all leading to her getting confirmation that this Noah she is speaking with, the one who split off from N just as she did from M is indeed not going to fall to despair and give up on his principles even if he ends up losing Mio.]]
* ShipTease: Almost from the start there are constant sweet moments between him and Mio, well before either even know what romantic love is. [[spoiler: They exchange their Off-seer flutes before infiltrating Keves Castle which is treated as an intimate gesture. When they see a couple kissing in the City both glance at each other before bashfully looking away.]]
* TrickedOutGloves: Drawing the Sword of the End will cause his red Blade to reform into an ornate gauntlet over his left arm.
* ThreeAmigos: Has this dynamic with {{Childhood Friend}}s Lanz and Eunie, much in the same way Shulk had Reyn and Fiora.
* WillfullyWeak: It was initially assumed that Noah could not summon his Blade and relied on a training sword to get by in practice. As Riku correctly surmises when he goes for a replacement sword after his old one was destroyed by Garvel, it's not that Noah couldn't summon it; it was that he lacked the spirit to fight seriously to want to use it effectively.

[[folder:Mio]]
!!Mio
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/xbc3_mio.png]]
[[caption-width-right:350:[[labelnote:Click here to see her Ouroboros form]]\\
https://static.tvtropes.org/pmwiki/pub/images/mio_7.png[[/labelnote]]]]
->'''Voiced by:''' Creator/MinamiTsuda (Japanese), Creator/AimeeFfionEdwards (English)\\
'''Class:''' Zephyr (base)\\
'''Role:''' Defender (base)

->''"Finding a path that lets us all live, I will make that my mission."''

A woman from Agnus and one of the two protagonists who, like Noah, is an "off-seer" from Colony Gamma.
----
* AlmightyJanitor: Mio is so skilled a warrior that it's likely she would've made it to Silver Rank, but despite her skills got assigned to being an off-seer with Miyabi.
* AmbiguouslyRelated: [[spoiler:Mio looks a lot like Nia, has a similar taste in weapons, and even shares her Flesh Eater Core Crystal. Nia mentions during their one-on-one conversation in her Hero Quest that out of everyone she wanted to meet Mio the most while she was still in stasis, feels that it was destiny that they should meet, and is about to say more on the subject before being interrupted by the rest of the party, and the ending reveals that Nia had a child with Rex. This all strongly implies a direct relationship of some sort that's more than mere coincidence, such as her either literally being Nia's daughter or a distant descendent from her, but it's never directly stated what that relation is.]]
* TheBard: Much like Noah, Mio is an off-seer, and was thus trained to play her flute to allow the souls of the departed to pass on to the beyond. She is also sometimes seen playing it at camp with Noah or- if she's in the party- [[spoiler:Miyabi]].
* CatGirl: Mio looks Gormotti, sporting feline ears, and is aligned Agnus, which is descended from the world of Alrest. To go with this, the English dub gives her a Welsh accent like other Gormotti (hers isn't as thick as Nia's, though).
* BecomingTheMask: She didn't choose to become an off-seer but was initially assigned as one despite her objections. After half-heartedly learning the melody and overseeing a couple of battles, she changes her mind and takes it much more seriously after Miyabi teaches her how important her role is.
* CoolBigSis: Sena's official character bio notes that she looks up to Mio like a big sister.
* DanceBattler: Noah notes that her fighting style is based around the rhythm of Agnian off-seer music.
* DidYouJustPunchOutCthulhu: [[spoiler:While enraged by Ethel's death, Mio (In ''human'' form) punches O and P in their interlinked Mobius form so hard that they're sent flying into a rock despite their massive size.]]
* DualityMotif: [[spoiler:Mio's new body used to belong to M of Moebius, and so when that fact is brought up, her Iris shows both the Ouroboros and Moebius symbols at once.]]
* ExoticEyeDesigns: Along with the Flame Clock and Ouroboros symbols in her Iris, [[spoiler:when Mio gains M's body, the Ouroboros and Moebius Iris combine to create a completely new symbol.]]
* ExpressiveEars: Her ears are drooped from exhaustion and thirst in a desert until Sena notices water, causing them to flip up before she dashes to it.
* EveryoneLives: As her quote at the top implies, she travels with Noah so they can find a way to ensure everyone can continue living, especially when they learn destroying the Ferronis' Flame Clocks allows the colonies to continue living without the need to kill others and steal their "flames".
* GameplayAndStorySegregation: Shortly after the start of Chapter 6, when she confides in Eunie and Sena about her new hairstyle [[spoiler:after switching bodies with M]], the player then decides on keeping her hair long or cutting it back to short. While the game implies this is a one-and-done decision, an Option opens up to allow changing Mio's hair at any time without affecting the story from that point on.
* HeyYou: She actually does not address Noah by his name in cutscenes nor gameplay after joining forces. [[spoiler:Near the end of Chapter 5, it is hinted by M, who already switched bodies with Mio by the time the Ouroboros gang has been imprisoned until the eclipse and Mio's Homecoming, that calling Noah by name would force her to finally confront her own feelings for him and break her heart. Though it is M most likely relating her thoughts about N during the imprisonment, she is still Mio at her core and is relaying what the current Mio feels from experience. Sure enough from Chapter 6 onwards, Mio does say Noah's name, an instance being that instead of prompting him if ''he's'' prepared when she initiates Interlinking, she proclaims that with ''Noah'', she can fight on]].
* InSeriesNickname: Sena refers to Mio as "Mimi".
* KickingAssInAllHerFinery: She's wearing her ceremonial-looking off-seer outfit during her squad's fight with Noah's prior to getting her standard outfit.
* LightningBruiser: While her [[https://twitter.com/NintendoAmerica/status/1493281649345413123 official bio]] emphasizes her speed and details how she uses it to attack, she is actually a ''tank'' in her default class, [[RecurringElement similar to]] 1's Dunban and 2's Mòrag. If anything, her HP pool is second only to [[TheBigGuy Lanz]]. During her battle with Noah when the two halves of the party first meet, Noah mentions that she's so strong and fast that he has use all his skill just to survive, and anything less would end in his death.
* MsExposition: [[spoiler:After being given M's body, she also inherits her memories, and with it, a ''lot'' of information on who and what the Moebius are.]]
* PunnyName: Similarly to how Nia's name in ''2'' is derived from "nyan," Mio's name comes from "meow," fitting her CatGirl design.
* RecurringBoss: She's fought at the beginning of the game alongside Taion and Sena, [[spoiler:and again [[FreakyFridayFlip in the body of M]].]]
* RingsOfDeath: As shown in her character art, she wields a pair of discs pretty close in appearance to chakrams without the inner handle. Separating them from a standard DeadlyDisc is that she fights with them in melee.
* ShipTease: Almost from the start there are constant sweet moments between her and Noah, well before either know what romantic love is. One notable scene has her initiate an exchange of flutes with Noah, who was confused at first at the idea, but consent soon after.
* SpannerInTheWorks: [[spoiler:She as M appears before Ghondor and Monica to warn them that the City's been compromised, foiling Moebius' attempt to destroy it with Castle Agnus' Annihilator.]]
* StepfordSmiler: She puts up a brave front most of the time, but she's in actuality deeply afraid of her coming death.
* StrongerThanYouLook: Not quite as strong as Sena, but despite her thin build with a running start she manages to [[spoiler:punch the Interlinked O and P so hard that they're sent flying into a rock.]]
* SuperHearing: As a Gormotti she naturally has sharp hearing senses and it comes in handy saving the party more than once. When Juniper first attacks the party, she's shown to detect their ambush attack on Eunie and push her out of the way, even though ambushes are stated to be Juniper's specialty.
* SuperSpeed: In her character video, Mio claims to be able to run 100 meters in 7 seconds, meaning she can run at over 30 mph. For comparison, the current world record for the 100-meter dash is held by Usain Bolt at 9.58 seconds, which is ''around 27 mph!'' "Super speed" indeed! [[GameplayAndStoryIntegration Fittingly]], she has the highest Agility stat of the main party.
* TalkToTheFist: [[spoiler:Shuts up the interlinked O and P by punching them as they start monologuing after Ethel and Camuravi's death, sending them flying without even being in Ouroboros form]].
* TomboyAndGirlyGirl: Shares this dynamic with Miyabi; Mio is more athletic and prepared for combat, to the point where Mio didn't even intend to become an off-seer, while Miaybi is the demure and delicate off-seer who doesn't like fighting. However, when it comes to the main party members, she's the girly-girl to Eunie and Sena's tomboys.
* YourDaysAreNumbered: While this is true for everyone in the party, Mio in particular only has about three months left in her Term. It's for this reason that Jeremy decides not to kill her when she offers her life in exchange for all the Kevesians she's killed over the years. [[spoiler:It's ultimately subverted when she and M switch bodies and she gains an immortal Moebius-made body.]]

[[folder:Eunie]]
!!Eunie
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/xbc3_eunie.png]]
[[caption-width-right:350:[[labelnote:Click here to see her Ouroboros form]]\\
https://static.tvtropes.org/pmwiki/pub/images/eunie_8.png[[/labelnote]]]]
->'''Voiced by:''' Creator/MegumiHan (Japanese), Kitty Archer (English), Emily Carey (Child English)\\
'''Class:''' Medic Gunner (base)\\
'''Role:''' Healer (base)

->''"Ready, he says. From the moment I chose this muddy path I've been more than ready!"''

Noah and Lanz's {{Childhood Friend|s}} with a sharp tongue and rough personality.
----
* AccentAdaptation: Speaks in a very rough and informal manner in the original Japanese script. Adapted into a thick Cockney accent in the English dub that puts [[VideoGame/XenobladeChronicles1 Xord]] to shame.
-->'''Eunie:''' Just par' o' the protocol, innit?
* BoomStick: Her main weapon is a staff that doubles as a rifle.
* BoyishShorthair: As a child her hair was short enough to give her an androgynous appearance.
* BrokenAce: [[spoiler:She was once the best sharpshooter in Colony 18, but was killed by D because her Colony was [[FatalReward Gold Rank]], which was the best Rank for a Moebius to drain life force from.]]
* BrutalHonesty: Eunie tends to be upfront about her opinions and isn't afraid of hiding it when she doesn't like someone, describing herself as someone who prefers to take things at face value. Used to hilarious effect with Ashera and Gray.
* CharacterTic: She'll tousle or tug one of her head wings when she's thinking or irritated.
* CombatMedic: As her official bio states, she fights using a MixAndMatchWeapon called a "Gunrod" which she can use to heal allies.
* ContrastingSequelMainCharacter:
** To Fiora from the first Xenoblade Chronicles. Both are the {{Childhood Friend|s}} of their respective main protagonists (Shulk and Noah) and both were seemingly killed by an AxCrazy maniac of a StarterVillain. (Mumkhar/Metal Face and D/[[spoiler:Blackblaze Dirk]]) However, while Fiora is [[NotQuiteDead revealed to be alive in a Mechon-like body]], [[spoiler:Eunie was killed by D during his raid on Colony 18 since it had the [[FatalReward Gold Rank]] and simply reincarnated into a new body as do all soldiers on Aionios who die before their Homecoming.]] Fiora is Shulk's love interest, whereas Eunie and Noah have a close but completely platonic bond.
** Likewise, she serves as one to Melia. Both specialize in ether and are High Entia, but they couldn't be any more different in personality. Whereas Melia was a polite, feminine refined princess with MysticalWhiteHair who spoke in Received Pronunciation and buried her feelings for the sake of not troubling others, Eunie has brown hair and is a tomboyish, brash pottymouth with a working-class Cockney accent whose BrutalHonesty makes her feelings on issues easily known all the time.
* DeadpanSnarker: Eunie has a sharp tongue and isn't afraid to speak her mind. A lot of the game's comedy comes from her wry comments at the events going on around them.
* DiscoveringYourOwnDeadBody: [[spoiler:She comes across the husk of one of her past selves decades after the destruction of Colony 18 and it deeply rattles her.]]
* TheLadette: She outstrips Lanz as the crudest, rudest member of the main party.
* LadySwearsALot: Out of the main party, she is by far the most foul mouthed, using both in universe language like "snuff" and "spark" alongside curses from English like "bollocks" and "arsehole".
* TheMedic: Like Taion, her starting class has her specialize in healing her allies in battle.
* MercurysWings: Has short wings on her head like other High Entia (though modern High Entia seem to mature at a regular human rate unlike their ancestors). It's theorized by Namuki during the Research Procedures quest that these wings are what give her and people like her (i.e. High Entia) such fine control over ether.
* MsFanservice: The closest thing this game has to one among the main cast, Eunie has the largest breasts out of the group, and her FormFittingWardrobe does the most to highlight her figure out of the protagonists.
* PastLifeMemories: [[spoiler:Eunie has memories of a previous incarnation fighting and dying against D around forty years ago, which is why she deeply fears him at first.]]
* ShipTease: With [[spoiler:Taion. Early in chapter 6 Eunie notes in a scene that gets special attention from the camera that she can be more optimistic now since she has "a reliable guy to stand with [her]." Taion is visibly flustered and asks that she outright confirm she is talking about him, Eunie teasingly noting it's a secret.]]
* SmarterThanYouLook: Despite her brash attitude and headstrong nature, she was actually a pretty good student.
* ThirdPersonPerson: Not always but she does frequently refer to herself in third person, mostly in assorted field lines.
* TsurimeEyes: Has upward slanting eyes and happens to be the main snarker of the party.
* VitriolicBestBuds:
** Even after she and Taion get over their initial animosity and become friends, she still very much enjoys busting his chops given the opportunity.
** Most of the Heroes whose class Eunie inherits have this dynamic with her, especially Ashera, who enjoys Eunie's threats while actively suggesting they become friends. Sena at one point outright says she can't tell if they're going to hug or kill each other.
* WhyDidItHaveToBeSnakes: Or Aspars, in this case. It's not out of fear but rather because she finds them [[{{Squick}} horrifically disgusting]] to the point she's noted to have almost vomited after fighting one. %%InUniverse

https://static.tvtropes.org/pmwiki/pub/images/taion.png[[/labelnote]]]]
->'''Voiced by:''' Creator/RyoheiKimura (Japanese), Olivier Huband (English)\\
'''Class:''' Tactician (base)\\
'''Role:''' Healer (base)

->''"If anything, we should be questioning all that we've thought to be true."''

Another soldier of Agnus, who fights alongside Mio. He's a tactician who fights with his smarts and insight.
----
* BlackAndNerdy: AmbiguouslyBrown in-game and voiced by a Black voice actor in the English version, and the soft-spoken [[TheSmartGuy Smart Guy]].
* ADayInTheLimelight: He's the central character in most of the Chapter 3 story beats as the audience is treated to a flashback of his past and the climax fight of the chapter deals with him confronting and overcoming it.
* DeadpanSnarker: Relatively polite and refined, but at times among the most acerbic of the main cast, frequently making sarcastic jabs at Lanz and Eunie over their goofier antics.
* TheEeyore: The most pragmatic, but also the most pessimistic of the party, with the rest of the party frequently making fun of him for his tendency to be a downer.
* ICallItVera: He refers to his katashiro weapons as "Mondo" and dotes on them like pets.
* InsufferableGenius: Downplayed and subverted. He doesn't forcefully boast about his skills, and he's normally quite nice, but any praise at all generally gets him to smugly point out that he's ''always'' skilled in strategy -- given how said praise is generally in response to him pulling off a scheme or pointing out an obscured tactical insight, it's hard to blame him. He later admits openly that it's one of the few things he has confidence in.
* LethalChef: According to Manana he's not the best cook, and the main reason she learned how to cook was because of how bad he is at it.
* MasterOfIllusion: His Ouroboros form is capable of disguising itself as other things using illusions, such as when he disguises himself as Eunie's form while they're fighting D.
* MrExposition: As TheSmartGuy of the team, he is the most knowledgeable of the party on a great deal of information about Aionios and responsible for explaining a great deal of things about the setting and story. Being a tactician from a colony with an established espionage network, he also has a great deal of insider knowledge regarding the various colonies and their leaders.
* MyGreatestFailure: Before coming to Colony Gamma, Taion served under Isurd and was asked to come up with a plan to assault a Keves colony. Despite protests against the plan one of Isurd's men suggested, saying it was too dangerous and they lacked crucial information, Taion ultimately went with it while making some adjustments. Not only did the plan end in failure, one of Taion's commanding officers and mentor, Nimue, was killed in the process.
* NotSoAboveItAll: He has his moments, but a shout-out to the "City Clothing" discussion where after Taion claims to be above caring about style, he gets deeply offended when Eunie calls his scarf uncool. There is also a scene at the end of Lanz's Ascension Quest where he gets positively giddy over how delicious food in the City is, describing it in excited detail.
* NotSoStoic: [[spoiler:While the group is visiting the maternity ward, he loses his usual cool demeanor when he sees the newborn baby.]]
* TheOneGuy: Starts out as the only guy on Mio's team.
* PaperMaster: Uses origami constructs that take the form of Shinto charms called katashiro as a weapon, making protective barriers and forming them into large birds.
* ScarfOfAsskicking: He's a soldier who wears a long orange scarf. While in the "City Clothing" Camp conversation he claims he wears it for strictly pragmatic reasons, Eunie trolls Taion into revealing that he wears it because he thinks it's cool by claiming that it sucks and letting his reaction speak for itself.
-->'''Eunie:''' While we're on the subject, Taion. There's something I wanted to say for a while now.\\
'''Taion:''' What is it?\\
'''Eunie:''' Your scarf is deeply uncool.\\
'''Taion:'''[[note]]His speech bubble is now in "shouting mode"[[/note]] What did you just say?! Repeat yourself, I dare you!\\
'''Eunie:''' A-ha! I ''knew'' it! You're as vain as the rest of us, you poser!
* SesquipedalianLoquaciousness: Tends to use a lot of fancy vocabulary to reflect his role as TheSmartGuy. For example, he [[InsistentTerminology insists]] on referring to Armus by their technical name of Armuidae.
* ShipTease: With [[spoiler:Eunie. Early in chapter 6 Eunie notes in a scene that gets special attention from the camera that she can be more optimistic now since she has "a reliable guy to stand with [her]." Taion is visibly flustered and asks that she outright confirm she is talking about him, Eunie teasingly noting it's a secret.]]
* SmartPeopleWearGlasses: Wears a pair of glasses and his official bio notes that his role is to serve as the tactician of Mio's group.
* TheStoic: Generally reserved in the way he expresses his emotions, although he points out to Eunie that he's not nearly as emotionless as some might think.
* TheStrategist: Described in his official bio as a brilliant tactician for the Agnus army.
* TallDarkAndSnarky: The second tallest party member after Lanz, and highly respected by his Agnus peers for his intelligence and thoughtfulness, but also very snarky and constantly feels like he's SurroundedByIdiots.
* TokenHuman: Downplayed. While the various races seen are referred to collectively as "human", Noah is a Homs (noted to be a distinct race from humans due to their ether sensitivity), Lanz is a Machina, Eunie is High Entia, while Mio and Sena have Core Crystals indicating that they are a Gormotti Flesh Eater and a pure Blade respectively. Taion on the other hand is implied to be a baseline Alrestian human similar to the Mor Ardainians, Leftherians, and Tantalese (ie. Born from the Titans but looking explicitly human compared to the much more distinct Gormotti, Urayans, and Indoline), as he has no TronLines or visible Core Crystal, and by extension is the closest to a human from pre-Conduit Earth.

->'''Voiced by:''' Kohsuke Tanabe (Japanese), Creator/MutsumiTamura (Child Japanese), Jack Bardoe (English) , Magnus Irwin (Child English)\\
'''Class:''' Heavy Guard (base)\\
'''Role:''' Defender (base)

->''"What the spark are you on about?! I'm not gonna let you take the fall alone!"''

Noah's ally, who fights with a great sword that doubles as a shield. He's very dedicated to his friends, even putting himself in danger for them.
----
* AmazingTechnicolorPopulation: He has light grey and dark grey skin patterned with golden filigree, characteristics you'd find on a Machina.
* BeehiveBarrier: His sword forms an energy shield with hexagonal segments when planted.
* TheBigGuy: He is the largest and the most muscular party member.
* {{BFS}}: Carries around a greatsword that's wider than he is as his primary weapon. It's standard equipment for Heavy Guards.
* ButtMonkey: Out of the main 6, he gets made fun of the most due to his crass behavior and not being particularly bright.
* {{Fanboy}}: Of Ashera, whose mere presence leads him to blush and stutter, to the amusement of his party members.
* FriendToAllChildren: Lanz tends to show his nicer side to younger characters such as Fiona and Valdi.
* GoodIsNotNice:
** A far cry from the Xenoblade tradition of a big, friendly musclehead, Lanz is neutral toward Noah and Mio, tentatively friendly with Sena, and constantly rude and abrasive toward pretty much everyone else, even potential allies he's just meeting. Special mention goes to his initially icy relationship with Taion.
** After learning that Consul J is [[spoiler:actually the Keves' group's deceased ChildhoodFriend Joran]], he goes to Riku and requests a weapon similar to the one he gave Noah with the explicit purpose of using it against J. Riku refuses, both because Lanz [[spoiler:did not consider asking Noah's input on the matter]] and that finding a weapon comparable to Lucky Seven is ''very'' difficult.
* HeroicBSOD: He doesn't take the revelation of [[spoiler:Consul J being none other than Joran]] very well; understandable given that [[spoiler:Joran saved his life when they were trainees and his sacrifice shook Lanz heavily]].
* HugeGuyTinyGirl: Lanz, the biggest person in the main party, forms an Ouroboros with Sena, the smallest person in the party.
* JerkWithAHeartOfGold: Lanz is perhaps the most abrasive of the main party, but he's a good person at heart.
* MixAndMatchWeapon: Like previous tank characters such as Reyn, Lin, and Tora, his sword can also be used as a shield, and like Lin it doubles as a minigun.
* MoreDakka: His weapon contains a turret that can rapidly fire shots, as seen when he uses Variable Turret.
* MyGreatestFailure: During Agnus' assault on Colony 14, Lanz was saved by Joran [[HeroicSacrifice at the cost of the latter's life]]. While this weighs heavily on Lanz already, he never managed to apologize for blowing up at Joran after he got himself "killed" in the trial against Garvel.
* NeverGotToSayGoodbye: Part of the reason he gets so beaten up defending his friends is out of guilt for never apologising to Joran for treating him poorly, mixing with PartingWordsRegret.
* RecurringElement: His official bio describes him in terms similar to Reyn, noting that he wields a shield weapon and takes damage to protect his friends, making him this series' defense tank.
* SuspiciouslySimilarSubstitute: Does a muscular childhood friend of the protagonist who puts himself in danger for his friends and wields a weapon doubling as a shield sound familiar? He definitely bears some resemblance to Reyn. He also has a similar English voice and accent to Reyn, and has the same Talent Art as him (Mad Taunt).

[[folder:Sena]]
!!Sena
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/xbc3_sena.png]]
[[caption-width-right:350:[[labelnote:Click here to see her Ouroboros form]]\\

->'''Voiced by:''' Creator/MiyukiSato (Japanese), Rebecca [=LaChance=] (English)\\
'''Class:''' Ogre (base)\\
'''Role:''' Attacker (base)

->''"The truth is, she's terrified. She needs someone to tell her that everything will be alright."''

Another Agnus soldier, who, despite her petite figure, fights with a giant hammer. Although she's shy, she bears a special connection with Mio.
----
* AffectionateNickname: Refers to Mio as "Mimi" and by the end of the game Lanz as "Lanzy".
* AloneInACrowd: Looking through her memories, Lanz notes that while she was constantly surrounded by people, she still felt deeply lonely and isolated from others, even those who were kind to her, her own lack of confidence coloring how she viewed others treatment of her.
* BareYourMidriff: Wears a sports bra and a cropped jacket that shows off her midriff and navel.
* CuteBruiser: She looks fragile, but, as stated on the official site, wields immense physical strength.
* ADayInTheLimelight: Much of her character arc is explored in Chapter 5, exploring her inferiority complex and meeting someone she could have become if she had chosen a different path.
* DropTheHammer: Her weapon is a giant hammer.
* EtTuBrute: Does not take [[spoiler:Shania's betrayal of the party to Moebius]] well after their perceived bonding moment.
* FlamingHair: The blue tips of her hair emit a blue flame.
* {{Foil}}: To Shania. Both girls were considered outcasts in their youth but eventually befriended and latched on to a girl more popular and talented than them, and their resulting inferiority complexes drove them to emulate their idols in any way they could. The only difference is that Shania couldn't let go of the past and became obsessed with surpassing Ghondor, while Sena eventually grew out of it and decided to embrace her own personal qualities.
* GlacierWaif: Lampshaded by official descriptions that contrast her petite figure with her titanic hammer.
* TheHeart: Sena serves as the emotional center of the party, starting off with positive relationships with just about everyone else when they're still overall at the standoffish if not outright TeethClenchedTeamwork stage, and having perhaps one of the highest levels of emotional intelligence amongst Ouroboros even if her tactics can be lacking. She and Lanz hit it off right away despite the latter's vocal grudge against Agnians, and she's the most into the icebreaker the party has following being deemed fugitives by their respective nations, playing a subtle but important role in getting everyone to bond as opposed to simply being allies of convenience.
* HiddenDepths: Beneath her boisterous exterior, she's a deeply lonely person.
* HugeGuyTinyGirl: Sena, the smallest person in the main party, forms a Ouroboros with Lanz, the biggest person in the party.
* MorphWeapon: For some of her Arts Sena can turn her hammer into a giant ball that she then hurls at the enemy, along with a barbell.
* MusclesAreMeaningless: She loves doing muscle training, but she has little to show for it with her tiny build.
* TheNicknamer: Sena is fond of giving affectionate nicknames to people she likes.
* PintSizedPowerhouse: She's very short but capable of easily tossing people twice her size over her head and wields a hammer about as big as she is as if it's as light as a feather. She's also seen pushing large rocks one handed when it takes Lanz two to do the same.
* PluckyGirl: Played with. This is what Sena ''wants'' to be and how she presents herself, as an energetic go-getter, even saying she'd like to be seen as a plucky heroine when Lanz confronts her about her real feelings. In reality, deep down she is lonely and lacks self confidence, hesitating for years to even believe Mio considered her a real friend and struggling to form her own identity. Her CharacterDevelopment is all about growing past this.
* StrongerThanTheyLook: Sena lampshades in her icebreaking conversation with the rest of the party how she's capable of lifting far beyond her own weight despite not looking it. When she and Lanz swamp classes for the first time, the latter's impressed that she can lift her hammer without a power frame, implying that it's about as heavy as it looks, and that she's even stronger than Lanz is.
* TomboyWithAGirlyStreak: A boisterous girl that loves muscle training, but also has slight elements of a ValleyGirl.
* TronLines: She has blue lines throughout her body. Along with her American accent in the English dub, they make her appear similar to a Blade.
* UnskilledButStrong: Alexandria notes that Sena is very strong but lacks much in the way of finesse.
* ValleyGirl: Has some elements of this in the English localization, mostly through her use of distinctly American teenager slang and vernacular in comparison to the majority British cast around her and other American accented characters who speak more formally.

!!Heroes

[[folder:In General]]
* AuthorityEqualsAsskicking: Many of them are the commanders of their respective Colonies as well as their strongest fighters. This means that recruiting the Hero to their cause also gives the party the opportunity to destroy that Colony's Flame Clock, freeing it from Consul control and opening up most of the other sidequests in that region. [[spoiler:Melia and Nia -- the ''real'' Queen of Keves and Queen of Agnus -- are the rulers of their respective nations and are more than happy to travel alongside the party, being two of the most powerful Heroes in the game.]]
* BadassNormal: Compared to the Ouroboros, Heroes don't have the ability to access other classes, change their gear, or transform into an invulnerable HumongousMecha at will, but they're still quite powerful in their own right.
* DefeatMeansFriendship: Nearly all of them are fought before becoming allies with Ouroboros.
* MegaManning: Recruiting a Hero also grants one party member access to their class, while the rest can unlock it through fighting battles alongside the Hero and/or their initial inheritor. Most of them get to show off what they can do as both an enemy and an ally before they properly join.
* OptionalPartyMember:
** Zeon, Teach, Gray, Isurd, Ashera, Alexandria, Fiona, Triton, Monica, Cammuravi, and Segiri are completely optional, [[spoiler:along with Nia and Melia]]. While Monica temporarily joins your party initially, unlocking her as a permanent Hero is optional.
** Ethel is an interesting case: while she joins your party as a Hero, plot events remove her from the roster [[spoiler:and she dies in Chapter 4, becoming completely unusable. While her Ascension Quest add her back into the party, it is also optional.]]
* ReasonableAuthorityFigure: Many of the commanders distrust the Ouroboros to one degree or another on their first encounter, but are usually willing to hear them out and very quickly come to see things the party's way. That the Consuls are addicted to being {{Bad Boss}}es certainly helps.
* YouHaveResearchedBreathing: Several Heroes will also teach the party a Traversal Skill, enabling them to do things like climb ivy-covered walls or walk up sandy slopes.

[[folder:Alexandria ''(Nina)'']]
!!Craftmaiden Alexandria
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/xc3_alexandria.png]]
->'''Voiced by:''' Creator/AmiKoshimizu (Japanese), Sharlit Deyzac (English)\\
'''Class:''' Incursor\\
'''Role:''' Attacker\\
'''Class Inheritor:''' Taion

->''"Doing the same as everyone around you, it's always the same outcome. Following the playbook to the letter is hardly a strategy."''

One of the Heroes from Agnus, hailing from Colony Iota. She is a famous soldier, renowned for her ability to analyze combat situations.
----
* TheAce: She's a skilled combatant with a tactical mind to match, which earned her Silver Rank.
* AwesomenessByAnalysis:
** During her first fight against the party she's able to easily ascertain their strengths and weaknesses, such as Taion's reticence, Sena being UnskilledButStrong, and Noah being a {{Determinator}} but having issues giving up when he knows he's outmatched.
** In the discussion topic Colony Iota's Goods, Alexandra mentions she was able to figure out that someone wanted to keep Agnus and Keves in a ForeverWar based on the data of the Collectopedia Card system she created, noting how the resources, supplies, and tech both sides used were even and balanced.
* BadassCrew: Unlike most of the commander Heroes whose troops are largely just cannon fodder, Alexandria's party is just as capable of keeping up with the Ouroboros as she is, and starting her quest causes several packs of them to deploy across the desert as ''far'' more powerful enemies than anything else in the region.
* BatmanGambit: Her plan to deal with the Ouroboros boils down to this. [[spoiler:By hounding them, she'd eventually force them to confront her, and by extension the Consul. As was her plan, since she wants Colony Iota to be free from the Flame Clock.]]
* BornWinner: The girls in the party describe her as one, and she certainly fits the bill as the exceptionally young commander of one of the most powerful and prosperous Colonies in all of Aionios. Where most Colony sidequests center around their persistent resource shortages, Colony Iota's are instead about having such an abundance of resources that they need to decide where to best trade their excess stock in exchange for future favors.
* CombatPragmatist: The first time Alexandria fights the party, she bogs them down fighting her underlings before attacking at high speed from behind with only Mio's hearing giving any warning.
* CriticalHitClass: Her class, Incursor, specializes in dealing critical hits for maximum damage, but at the cost of the damage bonus resetting if they're stunned.
* DubNameChange: Her name from the Japanese version has been changed from Nina to Alexandria in the English version.
* {{Foil}}: To Ethel and Ashera, skilled Commanders from Keves. Ethel was Silver-ranked but was dropped to Dirt when she refused to kill Cammuravi when his Ferronis malfunctioned and Ashera, another capable Commander, seems more interested in fighting than anything else. By contrast, Alexandria is cool and level-headed, keeping her Silver rank. Furthermore, whereas Ethel had to be broken out of her mind control by K to aid the heroes or Ashera asking for their assistance in taking down R, Alexandria [[spoiler:orchestrated things so that the Ouroboros would have to confront her eventually and give them a clear shot at Iota's Flame Clock. It also helps that she's technically been on the party's side from the start since she figured out someone was orchestrating a ForeverWar through her Collectopedia Card system]].
* TheGadfly: Loves to tease and confuse the party even after they officially become allies, Taion especially as a fellow tactician. In one camp discussion, they even remark how her smile tends to get a rise out of them, Mio and Sena excluded.
* GeniusBruiser: This game's Collectopaedia? Her invention, and she's no slouch as a warrior either in terms of strength or tactically.
* GirlyBruiser: Fond of wearing makeup and nail polish, and a powerful physical combatant.
* IDidWhatIHadToDo: [[spoiler:Q reveals that he learned from E that Alexandria had poisoned Iota's previous commander in his sleep in order to take his place, with her accomplices being her future subordinates. Alexandria states right afterwards that she has no regrets doing so, calling him a tyrant whose outdated tactics and wasting of men and resources would've ultimately gotten everyone killed.]]
* KlingonPromotion: [[spoiler:She got her commander position by poisoning the previous commander in his sleep, which she doesn't even deny, stating that she did it to save the Colony from his outdated tactics that were getting everyone killed.]]
* LightIsGood: More so than the other liberated Agnus Colonies. She's AMotherToHerMen, approved of a system where the ones who contribute to the colony the most get whatever they want within reason, and even somehow managed to convince Consul E to approve of the Collectopedia Card system used by Keves and Agnus to provide supplies to whoever needed them.
* PowerOfTrust: The neon-lit moral of her Ascension Quest. She thinks nobody trusts her because of her sordid past, and so she doesn't really trust anyone. [[spoiler:But when trusting Noah saves her from taking a cliff dive, she begins to open up, starting by agreeing to an engineering exchange with Valdi.]]
* PrimAndProperBun: She wears her hair in a bun to add to her regal bearing.
* StatuesqueStunner: She's taller than ''Noah'', which makes her age reveal all the more shocking.
* UnknownRival: To Valdi. Prior to the start of the game, Colony Iota and Colony 30 had a battle that, despite being Silver-ranked and having more supplies, ended in a loss for Iota due to 30 having superior mechs and just generally being impossible to read, due to the eccentricities of the residents living there. As a result, she's held a bit of a grudge against them for it. Valdi for his part, doesn't seem to recall this happening.
* WhatTheHellHero: After learning the true reason she fought the Ouroboros, Taion rips into her [[spoiler:for being so willing to sacrifice her troops just to get them to fight her head-on]]. Alexandria calls Taion "old-fashioned" because of this, though it's clear even she feels she's crossed a line.
* WhipSword: Her sword is able to extend into a whip for some attacks.
* WolfpackBoss: While the game recommends that you pick off her subordinates one by one while they're out on patrol, you can simply beeline straight to Colony Iota and fight her and all of them at once. However, it's only possible if you first wade through a crowd of grunts and an [[HumongousMecha Ulula]].
* YoungAndInCharge: She's only in her sixth term (15 in other words) and is effectively the head of Colony Iota.
* YoungerThanTheyLook: She looks like an adult, but she's only in her sixth term, making her roughly 15 years old, which is lampshaded by Mio, who thought she'd be closer to her own age. According to Alexandria and Chickadee, the method is a combination of cosmetics and affecting a regal bearing, and the reason is to protect the colony from its enemies by obfuscating when the soldier turnover will be. She makes the party promise to keep this a secret following her first Hero quest.

!!Undying Blade Ashera
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/xc3_ashera.png]]
->'''Voiced by:''' Creator/{{MAO}} (Japanese), Cassie Layton (English)\\
'''Class:''' Lone Exile\\
'''Role:''' Defender\\
'''Class Inheritor:''' Eunie

->''"Live fiercely, die spectacularly! That’s what I want the battlefield of my life to be."''

A hero from Keves and the commander of Colony 11 renowned for her skill in battle. She helps the party liberate her own Colony seemingly just for the fun of it.
----
* TheAce: Like Ethel, she's one of the few named Silver-ranked Keves Commanders and an absolute beast on the battlefield.
* AcheyScars: [[spoiler:Her neck scar appears and aches as her incarnations get older and she starts remembering how prior to the system of the Queens, Homecoming was just the Consuls personally executing soldiers that had reached the end of their lifespan in a ritual that supposedly celebrated and offered up "the light of their life". She states the pain will get worse and worse over time until she is driven insane by it and gets herself killed one way or another, and asks that Eunie end her life should it come to that. It's not made clear if there is any way to avoid this fate, though Eunie's words that her life is not just her own anymore seems to motivate her to try.]]
* AmbiguouslyBrown: She has a darker complexion, but otherwise lighter than Taion.
* AtopAMountainOfCorpses: When the Ouroboros first meet Ashera, she's found lounging atop a pile of wrecked Keves mechs.
* BloodKnight: Her EstablishingCharacterMoment has her acting rather gleeful fighting her own countrymen, and is quick to rope the Ouroboros into helping her fight her own Colony and its Consul for no other reason other than it would be fun, which unsurprisingly makes said Consul call her a "beast". Even her own men share this attitude. Unlike the other Heroes, Ashera doesn't mind fighting until her final day or even if she drops dead in combat, so long as her death has meaning. [[spoiler:It's revealed that this is because of the torment borne of her multiple deaths at the hands of the Consuls suffered by each of her incarnations prior. In her mind, a glorious death is preferable to a undignified, humiliating execution or having to kill herself to escape the pain that awakens in her along with the neck scar.]]
* BrainwashedAndCrazy: During Ashera's second Hero quest, she gets brainwashed by Consul W and the party is forced to fight her.
* DoubleWeapon: Her weapon is a two-sided sword.
* {{Expy}}: Pretty overtly to Dunban from the first ''Xenoblade Chronicles''. She has a similar black hair color and tanned skin to him, a similar Received Pronunciation accent, is similarly FamedInStory among Kevesi Defenders as one of the strongest fighters in all of Keves, is similarly introduced fighting Kevesi automata that resemble the first game's Mechon, is a high damage output dodge tank just as he is, has five of his Arts[[note]]Demon Slayer, Gale Slash, Soaring Tempest, Jaws of Death, and even his signature Blossom Dance as a Talent Art.[[/note]], is referred to as a "beast" by Consul R just as Dickson refers to Dunban in the prologue of the first game, has a similar reckless and HotBlooded personality to him as he was in that prologue, and even a line where she refers to the CrapsackWorld of Aionios as "a world of strife".
* FamedInStory: According to Lanz, there's not a single Keves Defender who hasn't heard of her.
* {{Foil}}: To Agnus' own Silver-ranked Hero Alexandria. Ashera is a boisterous Commander who proudly calls the battlefield her home. Alexandria is more composed and tactical, not to mention she acts far more ladylike than Ashera does.
* HiddenDepths: Ashera's second Hero quest reveals that underneath her badass exterior and devil may care attitude to conflict is a deeply traumatized woman tormented by her past, or in particular [[spoiler:her past lives ending in her dying an ignoble death at the hands of the Consuls, or to suicide when the memory and pain from those executions returns in other lives]], which is the source of her desire to die gloriously, even if it's a friend who kills her.
* IAmVeryBritish: She has a Received Pronunciation accent that, along with her snarky attitude, makes her sound a lot like VideoGame/{{Bayonetta}} when speaking.
* MadeOfIron: After Eunie [[spoiler:shoots her dead center to snap her out of W's mind control, Ashera remarks a normal person would have been killed by that. Instead she feels invigorated.]]
* MeaningfulName: Ashera sounds very close to "Ashura", also known as 'Shura' in Hindu mythology. While "Ashura" are classified as guardian deities or rebelling against the gods, not unlike the Ouroboros who challenge Moebius, the "gods" of Aionios, "Shura" in Japanese Mythlogy is the name of a Buddhist God of War, referring to someone who fights without end with vicious, almost inhuman ferocity. Fittingly, Ashera is the biggest BloodKnight associated with the heroes.
* TheParagonAlwaysRebels: Not to the same extent as Ethel, but she's a famed soldier among Keves' Defenders and her Colony is currently ranked Silver, the second-highest position in the proverbial totem pole. However, she's also fighting against not just the Consuls, but also her ''own colony''; it's played with in that she's rebelling not because she learned the Consul's plans, but because she thinks fighting the Consul and her own soldiers would be fun (and she dislikes how the Consul only gives them fights they know they will win). To the bewilderment of the Ouroboros, even her men are happy to fight their Commander because she and the party will give them a good fight.
* PastLifeMemories: [[spoiler:In every life Ashera over time regains memories from past incarnations that appear to go back to around the very beginnings of the ForeverWar, as she recounts the fact that at the time the Consuls would just brutally execute soldiers that made it to ten instead of having the Queen and off-seers send them off peacefully. Unfortunately, these restored memories come with other issues.]]
* RedBaron: Due to her prowess and enthusiasm on the battlefield, Ashera has earned herself the reputation of "Undying Ashera", but her more common title is "That Suicidal Maniac". She laments how dull the latter sounds, [[ComicallyMissingThePoint and nothing else]].
* ScarsAreForever: [[spoiler:Her neck scar always appears once she gets older, as a constant reminder of her deaths at the hands of the Consuls.]]
* SuicidalOverconfidence: She's so bad when it comes to fighting against overwhelming odds that she's renowned throughout Keves as "That Suicidal Maniac".
* ThrowingYourSwordAlwaysWorks: In her very first scene, she throws her weapon at a Keves mech about to assault the heroes and hits it square in the face. It's a more practical move than in some other settings, as she can dematerialize the blade at will to call it back to her hand.

* BetterToDieThanBeKilled: [[spoiler:After O and P start forcibly draining his life force, he realizes he won't survive the battle and accepts Ethel's challenge to duel her where they both consequently kill each other.]]
* BladeOnAStick: He's shown to fight with a spear resembling a Blade's Megalance with flames engulfing the spear head.
* CastFromHitPoints: [[spoiler:The whole gimmick of Cammuravi's class, Seraph. He has enormously powerful Arts that cost 10% of his HP to activate, and once he's self-damaged for at least 35% of his maximum HP, he becomes Awakened and powers up his Talent Art.]]
* TheChessmaster: He's actually a very skilled strategist, as he's known to feign weakness to lure overconfident Kevesi armies into traps.
* CodeOfHonour: He's insistent on adherence to something called a Warrior's Way, and seems to believe everyone has one.
* EyeScream: When the Consul attempts to take control of him, he rips out his own left eye to prevent that. [[spoiler:His next incarnation gets it back, but is blind in that eye and suffers periodic pain in it as a result of his body remembering the injury.]]
* FateDrivesUsTogether: Believes this to be the case between him and Ethel, that one way or another they will always meet and become bound to one another, and [[spoiler:his first Hero Quest strongly supports this idea through the extreme coincidences that cause them to meet and partner up. Some memory of each other even is retained in their new lives from the previous ones.]]
* InfinityMinusOneSword: Cammuravi and his Seraph class are one of the most potent Attackers in the game, but can't be used until very late in the main story. [[spoiler:Ethel can't be re-recruited until even later, but she still leaves behind her Flash Fencer class until then.]]
* InterfaceSpoiler: While he appears early in the story, he isn't recruitable until much later, yet his silhouette can still be seen in menus.
* MutualKill: [[spoiler:He and Ethel manage to kill each other with stabs to their respective Ferronis' chest compartments.]]
* PlayingWithFire: Both his armour and his lance are engulfed in flames, and even his hair seems to be on fire, just like with Sena.
* RapidAging: [[spoiler:After his death, his next incarnation was aged up by Y's experiments, out of his belief that the flame of life shines brightest towards its end. As such, he looks just like he used to but he's a bit more naive than his original self.]]
* RedBaron: He is renowned as "Smoldering Cammuravi", befitting of his fiery appearance, and "Crimson Lotus Cammuravi" in Japanese.
* {{Samurai}}: His strict honor code, status as a renowned military leader, the general Japanese aesthetic of Agnus, and [[spoiler:his recurring self-sacrifice, in both the story and gameplay]], make Cammuravi rather samurai-coded overall.
* SatelliteCharacter: It's downplayed, but Cammuravi has a sum total of one scene alone (that being a scene that exists solely to show off his tactical skills) that Ethel is not a part of [[spoiler:before fighting and dying with her in Chapter 4. He never interacts with the party before said boss fight either, and his name isn't mentioned a single time the entire rest of the chapter following his death, with all focus being put on avenging or fighting for Ethel. Justified in that none of the party knew him personally at the time. He gets more personal focus when he's reborn]].
* ShipTease: Pretty blatantly with [[spoiler:Ethel. They want nothing more than to enjoy fair fights with one another, and even as they are condemned and dying both wish for nothing with their freedom than to cross blades with each other in earnest. Course during this particular life neither had any concept of romance, but the implications remain.]]
* SurvivalMantra: Has several, which he seems to recite in stressful situations [[spoiler:(namely when experiencing a fear of heights after he is reborn).]]
* WhyDidItHaveToBeSnakes: [[spoiler:As revealed on the ride to the City, Cammuravi is deathly afraid of heights. Taion decides not to tell him about how high his Ferronis was in his previous life.]]
* WorthyOpponent: According to the relationship chart, he and Ethel are "Fateful enemies". This changes to "Partners" eventually.

!!Silvercoat Ethel
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/xc3_ethel.png]]
->'''Voiced by:''' Creator/AtsumiTanezaki (Japanese), Lucy Doyle (English)\\
'''Class:''' Flash Fencer\\
'''Role:''' Attacker\\
'''Class Inheritor:''' Noah

->''"There you are! You monsters!"''

A military commander of Keves' Colony 4.
----
* TheAce: Described as such for her combat ability, having risen both herself and Colony 4 to Silver Rank when she was only on her third Term, ie. 12 years old.
* BadassBookworm: If the Ouroboros party walks with [[spoiler:Cammuravi]] in the City and they pass the bookstore, [[spoiler:Cammuravi]] will remark how Ethel enjoys reading [[spoiler:since her rebirth and has been making him get more books]].
* BetterToDieThanBeKilled: [[spoiler:Rather than allow O and P to completely drain away her life force, Ethel instead challenges Cammuravi to a final duel where they both kill each other.]]
* BigDamnHeroes: Years before the main game, Ethel single handedly saves a young Noah and his friends from an Agnus war machine.
* BoobsOfSteel: Gives Monica a run for her money for having the most noticeable bust in the game, and is a legendary Keves soldier whose abilities in combat and leadership allowed her colony to rise to Silver rank in record time. Indeed, it's stated that even on her own she's more powerful than some of the Consuls.
* BrainwashedAndCrazy: Like everyone else in Agnes and Keves, the Consuls hack her internal Flame Counter so she can only perceive Noah and the rest of the party as horrifying {{Living Shadow}}s -- the moment it's broken, she recognizes Noah and stops fighting.
* CoolBigSis: Has this dynamic with Noah, Eunie, and Lanz; she's (slightly) older than them and her experience saved their lives years before, and since then the three of them have looked up to her.
* DualWielding: She fights with two swords at once. Unlike with [[VideoGame/XenobladeChroniclesX Elma]] and [[VideoGame/XenobladeChronicles2 Brighid]], her left-hand sword is shorter, as is the case with most real-life styles.
* GlassCannon: Her Flash Fencer class has monstrously high damage output compared to everything else in the player's arsenal up to that point, but generates an equally monstrous amount of aggro and doesn't have much ability to take a hit. Her Acceleration Art pushes it even further by boosting her auto-attack and Arts speed, but also raising the damage she takes.
* GuestStarPartyMember: She temporarily joins the party in Chapter 3, but is forced to leave [[spoiler:when N threatens to destroy Colony 4 if she doesn't comply]]. She does return in Chapter 4, however, [[spoiler:only to get killed off]]. [[spoiler:Later she's reborn as a child and can be permanently re-recruited after a side quest that rapidly ages her back up thanks to the machines Y created to grow soldiers to their final Term.]]
* HeroAntagonist: She's only attacking the party because she thinks they're {{Humanoid Abomination}}s due to being BrainwashedAndCrazy. She's a perfectly nice person otherwise. [[spoiler:Though she's forced back into this when N blackmails her with Colony 4's safety.]]
* HonorBeforeReason: She defeated Cammuravi in battle when his Ferronis suffered a technical malfunction, but refused to kill him. Keves Castle demoted her all the way down to Dirt rank, the lowest possible ranking in the country.
* HowTheMightyHaveFallen: Played with. Her skills have not dulled at all, still holding the title of Silver Rank and remaining a fearsome foe on the battlefield. Her colony, however, has long since been dropped down to Dirt Rank, i.e. the bottom of the barrel.
* {{Irony}}: Her sparing Cammuravi in battle resulted in her colony's dropping to Dirt rank. Given the mid-game reveal that [[spoiler:the whole rank system is made to single-out the best colonies for Moebius to harvest life force from]], this act likely saved Colony 4 from destruction.
* MutualKill: [[spoiler:She and Cammuravi manage to kill each other with stabs to their respective Ferronis' chest compartments.]]
* MyCountryRightOrWrong: Despite the corruption of the Consuls being exposed, Colony 4's Flame Clock being destroyed, and her allying with Noah and his party, Ethel remains loyal to Keves. It's not until she sees the Queen actively complicit with the Consuls' corruption that she decides to rebel.
* NiceGirl: Very kind and understanding to her soldier's current plight and gives the party shelter after they save Colony 4. She also hunts for supplies solo to reduce casualties amongst her men.
* RedBaron: She's nicknamed "Silver Ethel" due to her getting her colony to that rank. Doubles as an IronicNickname due to currently being Dirt ranked.
* RedEyesTakeWarning: Same with other brainwashed Kevesian soldiers, the Flame Counter in her right eye glows red when hijacked by Counsuls.
* SexyWalk: While this walk is present with pretty much all the older female characters, the sway of Ethel's class outfit makes her hip movements particularly noticeable. There is also a portion of the game where you are required to follow her as she slowly leads you to a meeting room, giving the player ample opportunity to observe how she walks.
* ShipTease: Pretty blatantly with [[spoiler:Cammuravi. They want nothing more than to enjoy fair fights with one another, and even as they are condemned and dying both wish for nothing with their freedom than to cross blades with each other in earnest, and the sheer joy she displays as she fights him here is in stark contrast to her generally stoic demeanor. When Noah tells her about how he and the others became Ouroboros, she even laments the fact that she and (who is implied to be) Cammuravi weren't there as well (implying she wished for a relationship that went beyond fighting him as a enemy). Course during this particular life neither had any concept of romance, but the implications remain. The two are strongly drawn to each other after their revival, and upon regaining her adult body Ethel pledges to walk "hand in hand" with him from then on as they stand together in front of the rising sun. She also declares together she feels like they can do anything. Their mutual declarations of companionship with each other also seems to be what causes their Class Ranks to ascend.]]
* SuspiciouslySimilarSubstitute: To Mòrag, as a military commander with a DualWielding fencing style who initially opposes the party due to a misconception but joins them after the understanding is cleared up. Her English dub voice also sounds similar, only with an English accent instead of a Scottish one.
* WorthyOpponent: To Cammuravi; the reason she's currently Dirt ranked is refusing to kill him when his Ferronis broke through no fault of his own.

!!Proudbanner Fiona
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/xc3_fiona.png]]
->'''Voiced by:''' Creator/AoiYuki (Japanese), Rebecca Benson (English)\\
'''Class:''' Signifer\\
'''Role:''' Healer\\
'''Class Inheritor:''' Lanz

->''"I just wish I wasn't such a weakling, I can't run away from my responsibility."''

One of the Heroes from Agnus. The young commander of Colony Mu in Erythia Sea, her Class is a Healer Class called Signifer, which specializes in buffing itself and its allies.
----
* BadassAdorable: She develops into this as part of her backstory and character arc. By the end, she's able to cow Triton with words alone and join the party in taking on her entire Colony all while retaining her kind nature that everyone loves her for.
* BewareTheNiceOnes: In one sidequest, she manages to talk Triton into backing down from teasing her crew by threatening to not feed him. Lanz and Sena mention they're now afraid of ''her''.
* BladeOnAStick: Her weapon is a trident with a big red banner near the spearhead. She has the ability to rally allies behind her by waving it, represented in gameplay by the granting of random buffs to allies.
* CallBack: Two actually. Her purse bears the same symbol that's seen on [[Characters/XenobladeChronicles2OptionalBlades Electra/Raiko]] from the previous game. She's also a HornedHumanoid just like Electra and Kora and has electrical abilities like them.
* DubNameChange: In the English version she is named Fiona rather than Mashiro.
* FailureToSaveMurder: [[spoiler:She blames herself for Irma's death even though Irma would have killed her and Ouroboros otherwise.]]
* HornedHumanoid: She has a pair of small red horns on her head.
* InnocenceLost: Fiona's Hero Quest exposes her to the true danger of the war.
* LetsSeeYouDoBetter: How she got promoted to Commander despite her young age and naivete. Following the previous Commander's death, she broke down in tears, begging the Colony's Consul to change the way the Colony operates. The Consul's response was to put Fiona herself in charge and tell her that if she wants things changed, do it herself.
* LotusEaterMachine: [[spoiler:Her Hero Quest is named Transcendent Dreams for a reason. Ever since she was appointed leader of Colony Mu, the residents of the Colony have been deliberately misled by [[MasterOfIllusion Consul I]], being forced out at random to fight battles against illusionary Kevesi and fill the Flame Clock for I's nourishment. Meanwhile, they've been kept in the dark about everything from their supplies to their colony rank to the ''actual location of their Ferronis''. The illusion is broken when she enlists Ouroboros' help recouping her losses after a hard-fought battle, and they realize something is seriously wrong in Colony Mu.]]
* InSeriesNickname: She's nicknamed "Shiro-[[UsefulNotes/JapaneseHonorifics chan]]" in Japanese, "Fifi" in English.
* RandomEffectSpell: The Signifer class' Aureole and Cry of Faith Arts each apply a random buff, either one to herself or two to all party members.
* ShockAndAwe: Her trident is charged with electricity when used as a weapon.
* YoungAndInCharge: She's pretty young but is the commander of Colony Mu, though it's downplayed in the sense that basically everyone there is in their early teens at most.

[[folder:Ghondor]]
!!Wrathfist Ghondor Vandham
[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/xc3_ghondor.png]]
->'''Voiced by:''' Creator/SatomiAkesaka (Japanese), Dominique Moore (English)\\
'''Class:''' Martial Artist\\
'''Role:''' Attacker\\
'''Class Inheritor:''' Sena

A young woman in Agnus captivity. She's always followed by two escorts, who highly respect her. She's the daughter of Monica, making her the granddaughter of Guernica.
----
* TheAce: She was ranked first in the Ouroboros tests, while Shania by comparison was ranked 8th (admittedly out of a 100 people).
* EleventhHourRanger: While she can be used before, storywise, she and Monica join the party as they're travelling down Origin, the final area of the game, and are present for the battle against Z.
* BadassNormal: Manages to shatter Moebius S' Core with her fists alone.
* BareFistedMonk: She specializes in hand to hand combat using her gauntlet Blades.
* BodyguardingABadass: She has a pair of personal bodyguards even though she's stronger and more powerful than the both of them.
* BrattyHalfPint: Repeated disappointment with changing the world has made her into an angry KnightInSourArmor that regularly insults her own mother, referring to her as "Bitchqueen", due to her belief said mother is too reckless.
* BrutalHonesty: Ghondor never minces her opinions on events or people and says things as they are.
* CharacterDevelopment: When she's introduced, she pointedly mocks the party for wanting to fight the war against Moebius because of the massive amounts of deaths; she is content in the prison because while people will still die (including her), it will be fewer than if they tried to escape. After some convincing from Ouroboros, she is convinced to fight on.
* DisappearedDad: An NPC in the City comments their admiration for Monica's strength for pressing forward for the good of the City despite losing both her father and her spouse, the latter presumably being Ghondor's father. Monica's Hero Quest explains he died on a mission to collect ether 14 years ago, i.e. when Ghondor was only around 4 years old.
* EmbarrassingFirstName: Ghondor dislikes her name, but when Shania asks why she continues to go by it anyway, she says it's to keep her family close to her.
* JerkWithAHeartOfGold: Ghodor is rough around the edges but a deeply kind person underneath it, [[JerkassFacade though she'd rather die than admit it openly.]]
* MeaningfulAppearance: She wears a [[UsefulNotes/MartialArtsBelts black belt]], and is described as a proficient martial artist.
* MyGodWhatHaveIDone: She takes full responsibility for the aftermath of her Ascension Quest due to being indirectly responsible for the death of the Giant Tirkin and fulfills his dying wish to take care of his kids. She takes them back to Agnus Castle to watch over them there.
* LadySwearsALot: ''Is she ever.'' And unlike Eunie, with her mostly [[UnusualEuphemism flame-based]] profanity, her potty mouth uses actual profanity to really get across how rude she is. She calls her mother "Bitchqueen" and is rude to just about everyone.
* OOCIsSeriousBusiness: The aftermath of Sena's sidequest is one of the few times she calls Monica "Mother" rather than Bitchqueen.
* PintSizedPowerhouse: She's even shorter than the roughly under 5 feet tall Sena, and specializes in physical combat.
* PoorCommunicationKills: She had good intentions in telling Shania to stop trying to copy her and find her own identity, so that Shania would no longer be dependent on her. However, Ghondor's combination of BrutalHonesty and JerkassFacade caused Shania to think Ghondor hated her, kickstarting [[spoiler:Shania's StartOfDarkness and eventual defection to Moebius.]]
* PowerFist: Her profile picture shows her wearing two large, mechanical fists.
* SmarterThanYouLook: She doesn't seem like it, but her TP amount is actually on par with Taion, the smartest person in Ouroboros.
* {{Tsundere}}: Ghondor is quite willing to talk smack about the people she cares about, but loves them dearly.

'''Class:''' Full Metal Jaguar\\
'''Role:''' Attacker\\
'''Class Inheritor:''' Eunie

->''"Whoever goes up against me, they're getting crushed."''

One of the Heroes, whose allegiance is unknown.
----
* AttackDrone: In addition to his primary handguns, his Full Metal Jaguar class utilizes drones in combat which are each mounted with a {{BFG}} capable of firing sweeping laser attacks across a wide area.
* BadassCape: The primary costume component of his class is a tattered black cape.
* ChekhovsGunman: A more literal example than most, Gray is a completely optional hero that requires backtracking [[spoiler:whom is also a travelling resident of Swordmarch. A lot of things about him (such as the eyepatch) start to make sense once you head to the City, and if he's in your party while there, he'll comment on it and -- either directly or through inference -- let a few things loose a bit early (such as the fact the Lost Numbers also use Blades over traditional weapons, or telling you where to find important city personnel later on).]]
* FreezeFrameBonus: It requires getting a close look at him, but [[spoiler:Gray has visible aging lines along the exposed part of his face, an immediate indication that he's not from Agnus or Keves.]]
* GoodIsNotNice: Gray is good-aligned and has a hidden soft spot for Ouroboros, but he's also terse in demeanor and pretty ruthless. [[spoiler:When he and Ouroboros have cornered the hardliners, Gray says he'll kill Yarmil and only keep Broo alive for information and kill her if she doesn't tell him anything worthwhile, with both Lanz and Eunie remarking that he doesn't mess around.]]
* GunsAkimbo: He wields two guns.
* HappilyMarried: [[spoiler:He has a wife living in the City. It seems he's extremely rarely home and even when in the City will frequently refuse to visit his wife when he's "on business". Despite this, the marriage appears to be stable and happy, with his wife merely saying Gray's always been like this and she doesn't mind.]]
* MayDecemberRomance: [[spoiler:As eventually revealed on the Affinity Chart, his true age is 60 while his wife, Rozana, is 30 years old, half his age by a thirty year gap]].
* MythologyGag: His class is "Full Metal Jaguar", the same as Elma from ''VideoGame/XenobladeChroniclesX''.
* OldSoldier: [[spoiler:He's approximately the same age as Guernica (60), and was a close friend of his.]]
* RewatchBonus: [[spoiler:After learning he's from Swordmarch, it makes sense as to why the eye covered by his eyepatch lights up when activating Chain Attacks, as opposed to not lighting up at all like Riku and Manana or simply just lighting up the other eye -- he wears the eyepatch in order to avoid Moebius detection, not because of anything regarding his vision.]]
* SwordLimbo: In his character video he dodges Noah's sword by bending backwards, allowing it to pass over him.
* TerseTalker: Gray doesn't talk much and when he does it's straight and to the point.

->'''Voiced by:''' Creator/TomoakiMaeno (Japanese), Ian Bouillion (English)\\
'''Class:''' Strategos\\
'''Role:''' Healer\\
'''Class Inheritor:''' Taion

->''"That is my revenge! It's payback for Nimue dying with her wish unfulfilled!"''

A military commander of Agnus' Colony Lambda and Taion's former mentor.
----
* AdvertisedExtra: Isurd has maybe half an hour's worth of story relevance, is never directly fought (with his boss battle being fought against his Colony's Ferronis [[spoiler:which also is not being piloted by him to be begin with), and for most of his present day screentime, he's not even himself; rather, it's just a mudpuppet that looks like him. After the brief section of the game he and J debut in, he's only marginally more important than any other hero.]]
* AwesomenessByAnalysis: [[spoiler:When the real Isurd helps the party defeat the rampaging Auto-Levs during his Hero Quest, he strikes the final blow by having Taion collect a storm of energy discs from his guns inside his Mondo, then firing one shot at the perfect angle to send them all crashing into the Auto-Levs' weak points.]]
* BenevolentBoss: [[spoiler:Isurd spends a few of his sidequests working to improve amenities for his subordinates in Colony Lambda, and obviously seems to have cared for Nimue and Taion.]]
* DeadlyDisc: His Blade is a pair of energy disc guns wielded like DualTonfas. The discs are capable of bouncing off walls or changing trajectory mid-flight.
* ExhaustedEyeBags: Has prominent tired eyes due to being a heavily overworked bureaucrat. It actually comes up as a plot point in his Ascension Quest, which has the party find him a hot spa so he can take time off and relax.
* RedEyesTakeWarning: Subverted. Consul J initially wanted to use K's plan and manipulate Isurd into fighting the group by hijacking his Iris, briefly turning his left eye red, but thinks better of the plan and creates a clone with Isurd's feelings of hate towards Taion amplified. The mudpuppet still has his eye glowing red as part of the ruse.
* {{Revenge}}: Subverted. When the party first encounters Isurd, he makes it clear he hasn't forgiven Taion for his part in getting Nimue killed. After the battle, however, it turns out that the Isurd the group fought was actually a mudpuppet created by Consul J, representing Isurd with his feelings of revenge pushed to the max. Although the real Isurd does have some feelings of resentment for Taion, his fondness for him far outweighs the hate and knows Nimue's death is not entirely Taion's fault.
* StationaryBoss: Colony Lambda, obviously being a massive Ferronis, doesn't have the luxury of moving around in its boss battle. This can work to its favor depending on the player's build, somewhat, as its massive size makes it a lot harder to get any benefits from moves that require attacking from the side or behind.
* TheStrategist: During the conflict he has gained a reputation as a skilled tactician, a skill he has imparted to Taion.
* TronLines: Has blue lines on his face, which combined with his American accent indicates that he has Blade ancestry.
* WarmUpBoss: Not in the traditional sense - the fight with Colony Lambda is much too late in the game to count - but its ability to place down a unique area of effect that can debuff or damage characters is introduced here, and serves as an easily avoided and tutorialized version of similar, much more dangerous abilities used by lategame bosses such as [[spoiler:D placing down his own AOE debuffs in Cloudkeep, or Z shooting off pillars of fire in the final boss fight]].

'''Class:''' Stalker\\
'''Role:''' Attacker\\
'''Class Inheritor:''' Noah

A hunter from Agnus and commander of the abandoned Colony Tau.
----
* AmbiguousGender: Their gender is never referred to in Japanese, and in English, the pronoun "they" is used.
* AmbushEnemy: Not unlike an actual cat, their official bio states they use ambush tactics to hunt their enemies.
* BraidsOfAction: They have a single braid on the left side of their head, and they are a proficient archer, able to effortlessly survive in the wilderness.
* DubNameChange: Referred to as Juniper instead of Yuzuriha in the English verison.
* EnergyBow: Their bow is solid, but its bowstring and arrows are made out of bright-green energy.
* TheFatalist: Juniper and their colonists are fully apathetic about their Flame Clock running out, considering it to be simple natural selection at work. Between this and Colony Tau's location in the nearly impassable Maktha Wildwood, their Flame Clock is almost completely empty.
* ForestRanger: Juniper is both this ''and'' the CityGuards, given the dual nature of the Maktha Wildwood.
* GrindBoots: They teach the Traversal Skill which allows the party to grind down ropes to new areas.
* LoveAtFirstSight: Is on the receiving end of this when Kite first meets them during Zeon's Ascension Quest, though neither one of them have a clue that that's the case.
* {{Multishot}}: In their character video, they fire three arrows at once.
* TheStraightAndArrowPath: Their weapon is a bow that fires explosive arrows. As shown by Eunie, Riku, and Valdi, guns are readily available in the setting.
* TrickArrow: During their attack on the party, their arrows are shown to explode shortly after hitting the target.

'''Class:''' Troubadour\\
'''Role:''' Healer\\
'''Class Inheritor:''' Mio

An old friend of Mio and Sena's and a fellow Agnian off-seer.
----
* CameBackWrong: After her death, she was revived by Y but placed under his control along with certain other soldiers from both factions until Mio and Noah manage to snap her out of it. Then inverted in that unlike the other revived characters (who get few or no restored memories) she gets ''all'' the memories of her previous life back. How exactly is not understood by the party themselves.
* CombatHandFan: Her main weapons are a pair of combat fans.
* ColorMotif: Contrasting Mio's off-seer outfit that's white with red accents, Miyabi's is white with green accents.
* DistaffCounterpart:
** Her being an off-seer who doesn't actually like fighting and is willing to off-see even the enemy faction brings to mind a female, Agnian version of Noah.
** Her being the person who exemplified everything an off-seer should be to Mio before dying brings to mind a female version of Crys, Noah's off-seer mentor.
* GameplayAndStorySegregation: Her being TheKlutz doesn't affect her performance in battle and, while she's stated to dislike fighting, she still willingly takes up her fan without complaints when called upon by the party.
* HeartDrive: Miyabi looks almost completely baseline human save for the square Core Crystal in her chest.
* HeroicSacrifice: Sacrificed her life to save Mio and Sena from deadly gas within Colony Omega.
* KickingAssInAllHerFinery: Fights in her ceremonial-looking off-seer outfit.
* IKnowYoureInThereSomewhereFight: She's on the receiving end of this when Noah and Mio convey their feelings through their off-seer melodies to break her free from Y's brainwashing.
* TheKlutz: In comparison to Mio being a skilled soldier, Miyabi was infamous for being very clumsy, though she personally doesn't mind because she doesn't particularly like fighting.
* NiceGirl: She gets along with the residents of the City so well that, by the time of her Ascension Quest, Travis introduces her at the cooking contest as, "Everyone's Sweetheart."
* RedEyesTakeWarning: Her left eye glows red while under Y's control.
* SupremeChef: One in the making after her Hero Quest, where she takes place in a cooking contest and earns praise from all the judges despite only bringing forward a simple ''teishoku'' meal. Following the contest, she asks Manana to teach her more about cooking, and the Nopon is more than happy to name Miyabi her apprentice.
* TomboyAndGirlyGirl: Shares this dynamic with Mio; Miaybi is the demure and delicate off-seer who doesn't like fighting, while Mio is more athletic and prepared for combat, to the point where Mio didn't even intend to become an off-seer.

* LuckilyMyShieldWillProtectMe: Her Lost Vanguard class uses a massive tower shield in tandem with a mace.
* MarriedToTheJob: When one of her subordinates/former Ouroboros candidates confesses his feelings for her at the end of her sidequest, she cites the fact that she's not only [[InappropriatelyCloseComrades his commanding officer]], but one of the Elders of the City, as a reason why she can't return his feelings right now.

* TheMatchmaker: Downplayed. After explaining a bit more about human romantic relationships following the party learning how babies are made in the City, Monica notes the potential between Noah and Mio by stating that they might've already figured out the newly learned concept of romantic love.
* MsExposition: Explains the nature of the City and how humans are supposed to work with the party, in a way almost acting as the closest thing they've ever had to a parent.
* NotSoAboveItAll: Comes across as a no-nonsense leader, but names her famous curry "[[{{Pun}} Monicurry]]".
* ReasonableAuthorityFigure: Notably, when a group of Lost Numbers try to secede from the City, her first instinct when catching up with them is to question how [[DidntThinkThisThrough thought-out their plan was]], and to send them back to the City so that they can come up with an actual idea for secession, and then present it to the Senate. None of the Lost Numbers try to argue with her on this either, indicating that they realized she was right about them doing things too fast.
* SexyWalk: Her hips are given a pronounced sway when she walks in cutscenes.
* TeenPregnancy: Looking at her and Ghondor's ages in the Affinity chart (33 and 18 respectively) makes it clear that she had her when she was only in her mid-teens.

[[folder:Riku and Manana]]
!!Peerless Riku & Manana
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/xc3_riku_and_manana.png]]
[[caption-width-right:350:Riku (right) and Manana (left)]]
->'''Voiced by:''' Creator/SayakaSenbongi (Riku); Creator/AyaSuzaki (Manana) (Japanese), Tarinn Callender (Riku); Grace Saif (Manana) (English)\\
'''Class:''' Yumsmith\\
'''Role:''' Attacker\\
'''Class Inheritor:''' Sena

->'''Manana:''' Maybe it impossible for one Nopon...\\
'''Riku:''' But not for two!

A pair of Nopon who accompanies the protagonists on their adventure, with Riku originally with the Keves trio and Manana with the Agnus trio.
----
* AdvertisedExtra: PlayedWith. Despite being with the Party since the beginning and showing up in almost every cutscene, they only become heroes and assist the main characters in combat during the middle of the third chapter. Additionally, unlike Tora or Riki (Tora especially) they have very little direct plot relevance, mostly serving as ways for the main characters to bounce off in CharacterDevelopment.
* BigAnimeEyes: Riku and Manana sport detailed anime-style eyes unlike the typical BlackBeadEyes seen on Nopon in previous ''Xenoblade'' entries.
* BigOlEyebrows: Riku is seen sporting a pair of prominent eyebrows which the official Twitter account describes as "dapper".
* TheBlacksmith: Riku is in charge of item crafting.
* TheDividual: Though being two Nopon, they fight together as one unit, Riku using a pistol and Manana using [[LuckilyMyShieldWillProtectMe a cooking pan that doubles as a shield]].
* FryingPanOfDoom: Manana uses a combat rated Nopon cooking pan, which noticeably glows green like Agnian Blades.
* FunnyAfro: Riku appears to have one. It's unclear if it's his hat or his hair, though when reclassed to Yumsmith, Noah and the other Keves characters get an ''ushanka'' that looks like it.
* MeaningfulName: Riku's name is derived from the Japanese word for "land", which goes along with his knowledge of gemstones and ores.
* MixAndMatchWeapon: Riku's pistol can turn into a laser sword.
* MysteriousPast: [[spoiler:It's implied that there's much more to Riku than meets the eye. When talking about how the Lucky Seven came into Riku's possession, Noah begins to suspect that Riku isn't exactly who says he is, but Riku feigns ignorance. Later, when Melia is freed from captivity, she apparently recognizes Riku and they share a glance, but doesn't comment on it otherwise.]]
* NervesOfSteel: Riku's Japanese profile describes him as someone who doesn't panic in any situation.
* NotSoStoic: Despite his usual stoicism, [[spoiler:in the ending when Agnus and Keeves must separate into two worlds again]], Riku's seen bawling his eyes out over the [[spoiler:possibility of never seeing Manana again.]]
* ObsessedWithFood: Nintendo of Japan describes Manana as always thinking about food.
* SixthRanger: They travel with Ouroboros throughout the whole adventure even though their presence in the actual battle party is optional.
* TeamChef: Manana's official profile describes her as the resident chef for the team.
* TrueCompanions: With each other and the main party. That last one is really relevant with the reveal the Nopon aren't [[spoiler:under Consul control.]] Meaning these two could just up and leave if they so desired without having to worry about Moebius targeting them, but they love their friends enough to stand by them.
* VocalDissonance: Riku has a very deep BadassBaritone in the English dub despite being a Nopon and speaking in their normal manner.
* UltimateBlacksmith: Riku is one of the seven Legendary Nopon who can wield Ultimate Hammers and work with [[spoiler:Origin metal to upgrade the party's initial Blades]], which also means he may have personally helped forge [[AbsurdlySharpBlade Lucky Seven]] (depending on just when it happened, since he states he was taught by a previous Legendary Nopon). The details of how this came to be are another element of the Nopon's MysteriousPast.

[[folder:Segiri ''(Nagiri)'']]
!!'''No. 7 Segiri'''
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/segiri_hero_artwork.png]]
->'''Voiced by:''' Creator/AiKayano (Japanese), Brigid Leahy (English)\\
'''Class:''' Machine Assassin\\
'''Role:''' Attacker\\
'''Class Inheritor:''' Sena

A young soldier from Colony 0, a secret colony directly under Moebius' command tasked with causing trouble behind the scenes in order to keep the ForeverWar going. As a Machine Assassin, she pilots a MiniMecha known as a Ferron, functioning as a debuff-focused Attacker.
----
* BewareTheQuietOnes: Despite never raising her voice, she commands a lot of respect from her troops. She's about the only one who can get the hot-tempered No. 9 to stand down when she's in a bad mood simply by stating her name.
* CastFromLifeSpan: The Ferrons have a miniature Flame Clock tied to its pilot's lifespan, which will be heavily drained if its limiters were removed to increase power output. After Noah destroys them, the Ferrons can no longer drain life or remove their limiters, being powered by ether cylinders instead.
* CreepyChild: Segiri's assassin conditioning left her with a bad case of DissonantSerenity, to the point that she's A-OK telling Ouroboros to their face that she's part of Moebius' black ops team and was sent to kill them. One conversation with her reduces Sena to tears.
* TheDogBitesBack: After Consul F risks all her comrades' lives by overclocking their Ferrons against her wishes, then orders her to kill Sena, Segiri turns on him and mortally wounds him, allowing Sena/Lanz to finish him off.
* ExtremeDoormat: Due to her upbringing, she has a really hard time doing things for herself unless directly ordered. When told she's free now after F's death, she has to rationalize it by imagining "Segiri" and "No. 7" as two separate things with one ordering the other around, because she's just ''that'' dependant on the chain of command.
* MiniMecha: She uses a Ferron, which is essentially a miniaturized Ferronis.
* PeekABangs: They cover her left eye and add to the sense of mystery when the team first sees her face.
* ReiAyanamiExpy: A [[MysteriousWaif thin]], EmotionlessGirl with silver hair, bright red eyes, and in her early teens who ends up hospitalized and is deeply loyal to an abusive leader.
* RoboSpeak: Due to being raised as a subservient assassin, she communicates in a robotic fashion and refers to herself in [[ThirdPersonPerson third person]]. What's strange is that no one else in Colony 0 talks like this, even though they've also been raised the same way.
* SuspiciouslySimilarSubstitute:
** Her being a cyborg that rides inside a MiniMecha brings to mind the Poppibuster from ''2'', as well as sharing the same RoboSpeak mannerisms as both Poppibuster and the original Poppi, though obviously without the added Nopon dialect.
** The fact that her life is tied to her MiniMecha also brings to mind Fiora post-Mechonization from ''VideoGame/XenobladeChronicles1'', though unlike the latter, she seems to have been [[TykeBomb born for the role]] instead of subjected to UnwillingRoboticization. Her "No. 7" designation [[MythologyGag also happens to be]] the order in which Mechon Fiora joined the party in ''1'', which many players used as a nickname to refer to her without spoilers.
* TeenageWasteland: The 12-year-old Segiri is the Commander of Colony 0, and its de facto leader once she [[KlingonPromotion removes Consul F from the equation]].
* TokenMiniMoe: The youngest and smallest member of the party (not counting her mech), and cute in her own distinct way.
* TrademarkFavoriteFood: When Sena makes her onigiri as an apology for suddenly running away, she ends up liking it so much that her first independent desire is to have some more.
* TykeBomb: Eunie pegs her for about three terms old (i.e. 12), which is young for a frontline soldier even by Kevesi and Agnian standards.
* UnexplainedAccent: Segiri is the only Kevesi hero to have an American accent rather than an English or Irish one.
* UselessUsefulSpell: Machine Assassin is generally a pretty bad class for story bosses and high-level Unique Monsters, not because of any inherent weakness the class has, but because most of them have an outrageous level of ContractualBossImmunity that makes it nearly impossible to debuff them.
* YouAreNumberSix: Colony 0 is mentioned to scrub as much personal info from their future assassins during their growth to maximize efficiency; before meeting Ouroboros, she was nothing more than No. 7. Sena gives her the name Segiri (Nagiri) by combining "seven" ("nana" in Japanese) and "onigiri" because she doesn't want to call her by a number.
* YouDidntAsk: Her response when Sena asks her, "Why didn't you tell us about this?!" during an event is, "That line of questioning has never been established."
* YouHaveResearchedBreathing: Segiri unlocks the ability to traverse damaging terrain without harm.

[[folder:Teach ''(Shido)'']]
!!Inscrutable Teach
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/teach_hero_artwork.png]]
->'''Voiced by:''' Creator/HirokiTakahashi (Japanese), Martin T. Sherman (English)\\
'''Class:''' Thaumaturge\\
'''Role:''' Healer\\
'''Class Inheritor:''' Mio

Mio, Taion, and Sena's commanding officer from Colony Gamma. In addition to overseeing the colony, he acts as a harsh, but fair training instructor.
----
* TheDreaded: [[spoiler:As revealed by the Avenger in his Ascension Quest, Teach hides a past as the infamous Commander Oleg of Colony Chi. Known as the "All-Slayer" in Keves, he boasted superb effectiveness in battle but a very high mortality rate among his troops.]]
* DrillSergeantNasty: Don't like his polite demeanor fool you. Teach is ''very'' serious about his training regimens. According to Taion, new recruits would very much rather go onto the battlefield than partake in his training.
* IGaveMyWord: He is honor bound to never reveal the details of his past to anyone, despite having made that pledge to his former Consul.
* GoodIsNotSoft: Despite his polite demeanor, Teach is strict when it comes to his training.
* OnlyKnownByTheirNickname: It's pretty apparent that "Teach"[[note]]Likewise his Japanese name ''Shido'' is short for "leadership"[[/note]] probably isn't his real name, what with it being a rather on-the-nose description of his reputation as a fearsome teacher. [[spoiler:That's because it isn't as his true name is in fact "All-Slayer Oleg"]].
* MeaningfulName: He lives up to his name "Teach", imparting lessons to those under his care while also training them in combat.
* NoodleIncident: He once saw someone become corrupted by power and was eventually consumed by it. Who that person was and their connection to him is unknown, save for that it left a very lasting impression on him, but it's strongly implied [[spoiler:he was referring to his old self as All-Slayer Oleg]].
* ReasonableAuthorityFigure: Like Ethel, he's willing to hear the party out and even gives them a free shot at destroying Colony Gamma's Flame Clock. This puts him at odds with Consul G, who is none too happy with Teach's decision.
* SecretTestOfCharacter: Teach takes the Ouroboros to a secluded location under the pretense of eliminating a potential threat to the world. It's not until his health is depleted halfway that he reveals he wanted to test the heroes' resolve and whether they had control over their powers.
* ThatManIsDead: When [[spoiler:the Avenger]] calls him [[spoiler:Oleg]], he calmly states that he goes by Teach now.
* ThisIsGonnaSuck: Both Mio and Taion have this reaction when Teach invites them for "a little stroll," during his Hero Quest, knowing that it's going to be anything but due to being familiar with his training methods.
* WellIntentionedExtremist: Although he put the heroes through the aforementioned secret test to determine their character, he was wholly prepared to die at their hands or kill them himself, having seen what happens to people who become corrupted and consumed by their power. [[spoiler:And as the Commander of Colony Chi, he employed tactics that maximized his chances of victory but cost him lots of soldiers, due to his belief that the duty of soldiers is to stamp out evil at all costs.]]

[[folder:Triton ''(Triden)'']]
!!Defiant Triton

->'''Voiced by:''' Creator/TakayaHashi (Japanese), Stanley Townsend (English)\\
'''Class:''' Soulhacker\\
'''Role:''' Attacker\\
'''Class Inheritor:''' Lanz

->''"I may like an odd scrap with some tough 'uns, but goin' on some idiot adventure with 'em sounds fun, too!"''

The Consul and Commander of Colony 15. An oddball who seems to live for adventure more than anything, and refuses to be called T.
----
* BenevolentBoss: In contrast to pretty much every other Consul, Triton treats the people of Colony 15 as friends to him, and even asks the party to destroy their Flame Clock, only because he's unable to destroy it himself.
* CallingYourAttacks: When he sneak attacks Lanz, he does so while shouting "Man of the Sea Sucker Punch!" Somehow this still manages to work.
* {{Cloudcuckoolander}}: Triton is a Moebius who doesn't try to kill Ouroboros on sight, instead inviting them on a jaunt across Erythia Sea before encouraging them to smash Colony 15's Flame Clock. When the party presents his Lieutenant with valuable booty for his contest, he claims he beat them because he found a coconut that's larger than their fossil, and greater size means greater value. Even his own Colony's personnel admit that while they're grateful he treats them well, unlike most Consuls, they have no idea what's going on inside his head.
* CombatPragmatist: He's got no problem going for cheap shots in a fight, sucker punching Lanz while his guard's down.
* DeniedFoodAsPunishment: Fiona threatens him with this when he goes a little too far in playfully scaring her subordinates while visiting Colony Mu.
* DudeWheresMyRespect: Despite being both the Consul and Commander of Colony 15, it's residents have no problem arguing with him or even calling him an "ugly lump". However, this shows that they actually like him rather than fear him as he never retaliates outside out a bit of complaining.
* EstablishingCharacterMoment: He catches the party off guard while they are out exploring. After they draw their weapons in self-defense, Triton raises his fist...only to instead put his hand to his chin and remark at their impulsiveness before inviting them to come eat some food with him. The party is understandably bewildered by this but follows him anyway.
* EvilIsPetty: Subverted. While he doesn't like losing and starts a fight by sucker punching Lanz, he's far from being evil.
* TheFogOfAges: He's been alive long enough to start to forget things. And it's implied he became Moebius while he was getting up in age.
* FatherNeptune: One of the older looking Moebius members who lives by the sea and loves making sea-based metaphors.
* ForgetfulJones: As a result of having lived for so long, he admits that his memory isn't the best. His second Hero quest revolves around him trying to remember the location of an object that someone entrusted to him long ago, and he's even long forgotten how to activate his Moebius form since he hasn't used it in so long.
* HeelFaceTurn: Completing his quest and liberating Colony 15 will result in him joining Ouroboros as an ally. {{Downplayed|trope}} in that he was never evil and in fact deliberately sought to have his Flame Clock destroyed, something only Noah could do.
* ImmortalityImmorality: Inverted. If anything, him living for so long is why he's got the perspective to realize that what the rest of Moebius does isn't for him, and that it's not the length of life that matters, but what one does with it.
* JackOfAllStats: The Soulhacker can not only use the various Arts of Unique Monsters, but change its active role via its Role Skill, meaning that the class can fit nearly any role or situation in the game.
* MagikarpPower: His Soulhacker class starts out with very limited options, with only three Arts and no Skills or Talent Art to speak of, in addition to not being able to use any other class's Master Arts or Master Skills. However, whenever a new Unique Monster is defeated while someone is deployed with it, the class gains a new skill, Art, or Master Art that all characters can use from then on. Each of the skills and Arts also has its own upgrade condition, most of which can be completed simply by using it. With all of its abilities unlocked and upgraded, the class becomes extremely customizable and powerful, and its Talent Art increases in strength with each new ability.
* MechanicallyUnusualClass: Soulhacker can't equip the Master Skills or Master Arts of other classes, leaving it purely limited to its own skillset. It also passes no Master Arts or Skills to any other class aside from the Soul Hack skill itself, which simply allows unlocking new Soul Hacks without needing a Soulhacker in the party. Triton himself uses a completely different set of fixed skills and Arts, none of which are the same ones the Ouroboros get.
* MythologyGag: Triton calls himself and his crew "Men of the Sea" similar to the [[VideoGame/{{Xenogears}} Captain of the Thames.]]
* NoSenseOfPersonalSpace: He greets the party by getting so close into Lanz's face that they're almost touching.
* NoSell: He shrugs off a couple of cannon blasts when visiting Colony Mu and they mistake him for an enemy before the party clears up the misunderstanding.
* NobleDemon: Downplayed in that he's not afraid to resort to cowardly tactics in his attempts to best the party, but it's tame compared to his fellow Moebius. Aside from that, he treats the soldiers in his colony like his own crew and doesn't transform into his true form when he fights the party, saying that using anything other than his fists in a brawl would taint things.
* OneLetterName: Defied, despite the insistence of his fellow Moebius members he refuses to go by "T".
* {{Pirate}}: His main motif. He talks with a heavy sailor's accent, complete with plenty of nautical terms peppering his dialogue, and he asks the party to call him "Cap'n Triton". His Moebius helmet is even styled to look like a captain's hat, and he lets out a couple of "yarrrrr"s for good measure.
* PowerCopying: The main perk of his unique Hero class, Soulhacker. As a trade-off for not having any set Master Arts and Skills of his own, Triton can acquire the unique arts and skills of Unique Monsters when he defeats them.
* PunnyName: Fitting his {{Pirate}} motif, his Japanese name is one letter off from the word "[[BladeOnAStick trident]]", whereas his English name is a BarelyChangedDubName that's also named after a [[Myth/ClassicalMythology Greek god]].
* RatedMForManly: Big, brawny, boisterous, and his EstablishingCharacterMoment shows him with a freshly punched [[ThreateningShark Gyaark]] casually slung over his shoulder. He also has SuperStrength and creates holes in the landscape just by punching.
* SailorsPonytail: Visible alongside his beard once he removes his helmet.
* SeaDogBeard: An epic, unkempt one, grayed by age, and crusted with salt.
* SoreLoser: While he subjects the party to a series of challenges and handicaps himself for the sake of fairness, it becomes clear that he never intended to actually lose by the time he adds a fourth part to his triple challenge. After he loses that, however, he admits defeat with no complaints.
* SuperStrength: He's strong enough that a friendly pat on the back sends Lanz, the biggest member of the party, stumbling, and he can casually defeat giant monsters.
* TokenHeroicOrc: He becomes a recruitable Hero after completing his quest, making him the sole Moebius to side with Ouroboros. He even requests that the party destroys his Colony's Flame Clock.
* WhiteSheep: Disregarding M, I, and J's complicated cases, he's the only Moebius to not be a complete sociopath. Since his version of their trademark hedonism boils down to adventure and fighting stuff as much as he wants, he doesn't have the same total lack of care for humanity his peers show. In fact, he seems to really appreciate the people he hangs out with, and openly asks the Ouroboros to bust his Flame Clock just to see what they'll be able to do without being shackled to it.
* WillfullyWeak: Subverted. When asked by Taion why he didn't transform against them during their battle, Triton says initially that he would rather not use anything other than his body and fists, only to admit immediately after that it's been so long since the last time he transformed, he straight up forgot how to.
* VagueAge: In the Affinity Chart, he is ??? years old. Unlike previous Xenoblade games, this isn't because his real age is a spoiler, it's just because he doesn't know how old he is.

->'''Voiced by:''' Creator/YuuKobayashi (Japanese), Mack Keith-Roach (English)\\
'''Class:''' War Medic\\
'''Role:''' Healer\\
'''Class Inheritor:''' Lanz

-> ''"It's just that, as a Mechanic, you can't start getting moody just because something's broken."''

A mechanic from Keves, who attacks the party to test his mechs against them.
----
* ActualPacifist: After the party inspires him to build a helpful non-combat Levnis, but it's wrecked by Consul Q, he resolves to keep Colony 30's hands clean from combat.
** BadassPacifist: And he goes about it the only way a genius RobotMaster knows how. By researching Agnian Auto-Levs (and restoring friendly relations with Colony Iota in the process), he builds Dorrick, a huge Gastrates that can defend Colony 30 from Levnis attacks by redirecting their targeting systems to not recognize anyone as a combatant.
* AloofLeaderAffableSubordinate: Inverted. Valdi's a lot nicer than his Lieutenant Yuzet, but only because Valdi isn't very good at his job and Yuzet ends up saddled with all of his work.
* AuthorityInNameOnly: Officially, he's the commander of Colony 30, and was promoted there on the basis of his raw engineering skills. The thing is, he either doesn't know or doesn't care about ''anything'' that doesn't involve robots, so his [[NumberTwo second-in-command]] is for all intents and purposes the real administrator of the colony.
* CombatMedic: One of the purest Healers in the game, there are no classes that can beat War Medic in terms of flat-out restoring health. It has solid support capabilities too.
* DubNameChange: His name is changed from the rather mundane "Rudy" to the more fantastic "Valdi" in the English version.
* FriendlySniper: The gun Valdi (and anyone else who's using War Medic) uses for his class is extremely similar, if not identical, to Mwamba's in terms of model and attack animations, and it's pretty clear Valdi's... a tad too nice to be a soldier. Immediately after jumping the party with a pair of Levnis, he starts having small talk with them about his mechs and their technical details. Heck, the kid has to be reminded that he's trying to fight Ouroboros and that they're supposed to be evil ''with the party themselves'' being the one to tell him this before he actually does it.
* TheEngineer: He focuses more on working on the mechs of Colony 30, despite being the Colony's commander. He is said to be the best mechanic in Keves.
* GeniusDitz: He's Keves' most feared Levnis technician, but his people skills are a little south of sufficient.
* HealingShiv: As is Xenoblade tradition, Valdi's gun fires bullets that spread ether into the air and have a restorative effect on tissue... [[HandWave or something]].
* ICallItVera: His description on the Japanese Twitter mentions that he names each weapon he works with.
* PrettyBoy: It's pretty easy to mistake Valdi for a girl.
* RobotBuddy: Built one named Mechafriend after the party convinces him to build something he wants to build himself. It ends up saving his life after Consul Q seizes control of his incomplete siege Levnis in an attempt to kill him.
* RobotMaster: He commands Levnises, the Mechon-like battle machines employed by both Keves and Agnus. Rather than seeing them as mere weapons, he considers them his friends and hates how they're incessantly forced to kill and destroy because of the war.

->'''Voiced by:''' Creator/RyotaOhsaka (Japanese), Neil Newborn (English)\\
'''Class:''' Guardian Commander\\
'''Role:''' Defender\\
'''Class Inheritor:''' Noah

A Keves soldier from Colony 9 who was friends with Noah and his group. After the latter are branded as traitors, Zeon is named the new Commander of Colony 9.
----
* CallToAgriculture: Zeon quickly takes to the idea of becoming a farmer to solve Colony 9's food shortage. If brought to the desert, he'll comment on the sadness of a place with so little arable land.
* EarlyBirdCameo: Zeon can be briefly seen in the intro cutscene featuring Colony 9's battle with Colony Sigma, riding atop a Levnis.
* InadequateInheritor: Played with. Kite and some of the soldiers in Colony 9 regard him as this, feeling he's been failing in protecting and providing for the colony ever since he was named Commander. That said, Zeon has also been working his ass off and only really started to prove himself as the new Commander after Noah and the others killed the Consul and destroyed their Flame Clock.
* KnightTemplar: Subverted. At first it seems like he's fully bought into the spiel that Noah, Eunie, and Lanz have gone rogue. He keeps conversations to the minimum and bluntly says he expects them to betray him, even pondering in front of them if the Agnus assault in his Hero Quest is their doing. In truth, Zeon ''does'' still think of them as friends, but he feels as though their relationship has changed and their positions are far too different now. When Consul B reveals that he had been watching their entire battle with Agnus but did nothing to support Colony 9 and then insults the soldiers who died, Zeon declares that he would rather trust the "traitors" who risked their lives to protect the colony than a so-called leader who couldn't care less about its survival.
* KnightlySwordAndShield: He uses a sword-and-shield combo, and belongs to the Defender role.
* MercurysWings: He seems to be a High Entia hybrid, but his head wings are even smaller than Eunie's, [[UnevenHybrid suggesting that he has less High Entia blood than her]].
* RobbingTheDead: Due to the dire straits of Colony 9, Zeon is forced to scavenge supplies from the Everblight Fields, where the battle from the opening of the game took place, essentially looting Agnus and Keves dead troops alike. Kite's group is abhorred by this whereas Zeon [[IDidWhatIHadToDo felt it was the better alternative compared to raiding other colonies]].
* SwordBeam: His Art Celestial Blade attacks with a wave of energy from his sword.
* WeAreStrugglingTogether: The Colony 9 arc revolves around the conflict between him and Kite. The latter and some of the soldiers are convinced he's not fit to be Commander and work to help the Colony amid the supply shortages. On the other hand, Zeon has been seen as being more effective since Noah and company freed the Colony and has since been trying to implement farming methods (albeit with mixed success prior to his second Hero Quest). For Zeon's part, he doesn't seem to mind that Kite is trying to undermine his authority and understands that he's simply concerned about the Colony's future.
* WeUsedToBeFriends: A more positive example than most. When the Ouroboros Keves group are named traitors and Zeon encounters them again, their different positions and loyalties makes him think their relationship isn't the same anymore and is unsure how to interact with them. It takes until the end of his Hero Quest and Noah's words for him to realize that they are still friends even if things might be different.
* YouAreInCommandNow: After the events of Chapter 1, the previous Commander of Colony 9 was forced to step down. Zeon was named as his replacement, though many including Kite believe he's not doing enough for the colony. He himself contemplates yielding his position in favor of allowing the colony to vote for whoever they thinks is best suited to lead them.

->'''Voiced by:''' Shiori Katsuta (Japanese), Creator/JennaColeman (English)\\
'''Class:''' Royal Summoner\\
'''Role:''' Attacker\\
'''Class Inheritor:''' Noah
->''"I had... a very long dream."''

The true queen of Keves, returning from ''VideoGame/XenobladeChronicles1''. For tropes specifically pertaining to her original appearance, [[Characters/XenobladeChronicles1Protagonists click here]].
----
* TheArtifact: Even after the fake Queen is destroyed for good and Melia returns to her castle, it will still retain its {{Mordor}} ambience and background music. One would expect that it'd be a much more cheerful place similar to Agnus Castle and return to its former glory as Alcamoth, but it still remains bleak and gloomy even as its benevolent ruler returns and has a few sidequests to her name there.
* BadassInDistress: She has been captured by Moebius and is being used as an energy source.
* BigGood: Shares this role with Nia in the endgame, where the two Queens work together to unite the warring nations against Moebius.
* ContinuityNod: Her outfit in the epilogue and as a recruitable Hero is based on her ''Future Connected'' garb, and her energy wings are based on those of Telethia.
* ContraltoOfDanger: Jenna Coleman's performance here is notably deeper than in the first ''Xenoblade Chronicles'', where both she and her character were younger.
* CuteClumsyGirl: She notably lets out an "ouch!" when performing her returning Starlight Kick art.
* DarkIsNotEvil: She's first seen wearing the same somber black gown as her EvilDoppelganger, but herself isn't malevolent or even anti-heroic in the least. She changes into her contrasting white battle outfit for the final battle and postgame.
* EasterEgg: Having Melia in the party allows you to visit her room in Keves Castle, as a Secret Area labeled the "Queen's Chambers". It's not much, but she'll promptly tell the party not to touch anything as they enter.
* GlassCannon: Melia and her Royal Summoner class have a very high Attack stat and can rack up huge damage with Elementals, but have paper-thin defenses and can crumble quite easily.
* TheHighQueen: Carrying over from her role as Princess of the High Entia, she is the true ruler of the forces of Keves, and rescuing her is a pivotal point of the endgame.
* InfinityPlusOneSword: Her class is the strongest of the Attacker classes, and can only be used for postgame content (including her Hero Quest). Furthermore, her ascension quest requires all other colonies to be freed from their Flame Clocks.
* KingIncognito: Melia makes a point that her post-game adventures with the party are to be undercover, and nobody is to know that she's traveling the world. The in-game purpose seems to be to HandWave how NPC's don't act any differently when they see the Queen of Keves in your party, and why Kevesian enemies continue to attack you. Despite this, a few characters recognize her regardless.
* LightIsGood: Her battle outfit is a stark white, her MercurysWings give her an angelic appearance, and she's one half of the BigGood duumvirate.
* LongHairIsFeminine: Invoked. Having come into her own as the Queen of the High Entia, Melia let her hair grow out to better fit the role.
* MagicStaff: She wields the World Ender from ''Future Connected''.
* MercurysWings: Like all High Entia, she has a pair of large wings sprouting from her head. During her recruitment event, she even remarks on how similar hers and Eunie's are.
* PaperThinDisguise: Her Hero outfit is one, as she emphasizes that nobody is to know that she's leaving the castle to travel the world with Ouroboros. Keep in mind that she already showed her face to all her subjects earlier during the endgame.
* PostEndGameContent: Melia can be permanently recruited to the party after defeating the FinalBoss.
* PreviousPlayerCharacterCameo: She was one of the playable party members in her own game, and returns as one of the final recruitable Heroes in this one.
* ReallySevenHundredYearsOld: As a High Entia, her life spans centuries if not millennia. She still barely looks any older than she did in ''Xenoblade Chronicles 1'', if at all.
* RemoteBody: After being rescued, she reveals that she was watching the party's actions the whole time through the eyes of her RottenRoboticReplacement. It's unknown whether this means she had any control over the decoy beyond being able to destroy it when the party's lives were in danger.
* RoyalsWhoActuallyDoSomething: It's her belief that if a royal doesn't help their subjects there's no point in them being around at all.
* {{Teleportation}}: When Sena asks Melia if she needs needs an escort from Origin to get her to Keves Castle, she replies with a "might you have forgotten who I am?" and effortlessly warps to her castle.
* TomboyAndGirlyGirl: The refined, elegant long-haired Girly Girl to Nia's brash, snarky short-haired Tomboy.
* UltimateBlacksmith: Melia created the Sword of the End with the combined power of Origin and her own heart.
* WrestlerInAllOfUs: Starlight Kick, based off of wrestler [[Wrestling/TheGreatMuta Keiji Mutoh's]] Shining Wizard kick, returns as one of Melia's arts from ''Xenoblade Chronicles''.

[[folder:The Final Agnian Hero '''(MASSIVE UNMARKED SPOILERS)''']]
!!Nia ''(Niyah)'', Queen of Agnus
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/xc3_nia.png]]
->'''Voiced by:''' Creator/HitomiOhwada (Japanese), Catrin Mai-Huw (English)\\
'''Class:''' Lifesage\\
'''Role:''' Healer\\
'''Class Inheritor:''' Mio
->''"My name is Nia, and I am the Queen of Agnus... one wing of Aionios."''

The true queen of Agnus, returning from ''VideoGame/XenobladeChronicles2''. For tropes pertaining to her original appearance, [[Characters/XenobladeChronicles2MainProtagonists click here]].
----
* TheAgeless: As a Blade, Nia has no age. With the exception of cutting her hair, she looks just like her Blade form in ''Xenoblade Chronicles 2''.
* ArmorPiercingAttack: Her Lifesage class allows her to use attacks that can ignore an enemy's defenses.
* AutoRevive: Nia's Chain Attack Order lets her revive any fallen party members if completed, with increasing likelihood as her level increases. At higher levels, your party will be completely fine for Chain Attacks just as long as Nia herself is kept alive along with enough party members to reach 100%+ TP with her.
* BabiesEverAfter: Along with Pyra and Mythra, she had a child with Rex as seen in the ending.
* BigGood: She's the creator of the Ouroboros Stones, is awakened by the party late in the game, and serves as one of the most powerful forces for good in the final stretch of the story.
* BootstrappedLeitmotif: She's pretty much inherited ''Drifting Soul'' from ''2'' as hers. The original song played during several key emotional moments, with the most relevant one being when Nia revealed her Blade form to Rex and confessed her love for him.
* BoyishShortHair: As before, but with a twist -- she's in her Blade form this time, which was known for RapidHairGrowth when switching from her short-haired Gormotti form. She had a major haircut.
* BunnyEarsLawyer: While Nia serves as TheHighQueen, her true demeanor is still ''far'' from queenly, being the same headstrong, vulgar rebel she was in her younger years.
* CatGirl: She is a Gormotti, one of a race of cat people, although in reality she is a Flesh Eater Blade forced to consume her Gormotti sister.
* ContinuityNod:
** Her outfit in the epilogue and as a recruitable Hero is based more on her Driver outfit than her Blade one (unlike her royal robes). She also uses spectral versions of Pyra's and Mythra's Aegis swords in battle, and wears tights that very closely resemble Mythra's from her "Massive Melee Mythra"/''VideoGame/SuperSmashBrothersUltimate'' outfit as well as a white band around her right leg like the one Mythra normally wears, while her haircut more closely resembles Pyra's than her previous haircuts. She even mentions that the outfit was one made for her back when the worlds were separate.
** Her Enhanced Cellular Stimulus skill is based on when Nia used her healing powers to interfere with Malos' cells during their battle at the Cliffs of Morytha during ''2''.
* DisneyDeath: Right after she awakens, Nia is stabbed in the "heart" by D. However, after ''his'' death, she turns out to be none the worse for wear given that her Core Crystal is her ''actual'' heart.
-->'''Nia:''' Two cetris to the side and things'd'been a slight worse...
* DualWielding: Or rather, triple wielding. She wields three swords: her Catalyst Scimitar Blade weapon from ''Xenoblade Chronicles 2'', and spectral copies of Pyra and Mythra's Aegis Swords.
* FireIceLightning: A variation - when she uses her Divine Sword Talent Art, she performs a flurry of slashes with her water-based Catalyst Scimitar before grabbing her simulacra of Pyra's and Mythra's swords to strike the opponent as they glow with their original elements of fire and light, respectively.
* TheFogOfAges: When talking to Ghondor about Vandham and the events of Uraya in ''2'', she admits the events happened so long ago that she's forgotten most of the details, but the important bits of what happened remain.
* HarmfulHealing: Her Lifesage class gives her a chance to add her healing power as pierce damage on a hit. Said skill that grants this is called 'Enhanced Cellular Stimulus', no doubt inspired by the attack that she used to incapacitate Malos in ''[=XC2=]''.
* TheHighQueen: The true leader of the forces of Agnus, she sealed herself away in the Cloudkeep to evade Z's clutches while the Consul installed a robotic decoy in her stead.
* InfinityPlusOneSword: As stated in-game, Nia's Lifesage class is the most powerful of the Healer classes. She can only be used for postgame content (including her Hero Quest). Furthermore, her ascension quest requires the player to trudge through an area of aggressive Level 90+ monsters.
* {{Irony}}: In ''VideoGame/XenobladeChronicles2'', Nia was a CrutchCharacter who often [[CantCatchUp couldn't catch up]] to the other Drivers when optimized and when the party gained access to more powerful Blades, not counting her (still not amazing) potential as a healing Blade for Rex. In this game, she's one InfinityPlusOneSword of two among the Heroes.
* LateArrivalSpoiler: For players who didn't play through ''2'', this is where they'll learn that the petite Gormotti girl Nia is actually a Flesh Eater Blade with supreme healing powers. Being a Flesh Eater made her an outcast in Alrest, but now she no longer needs to hide her true nature.
* LightningBruiser: Nia is both this and a SupportPartyMember. While her main focus is on healing, she also has high Attack and the Steelcleaver gem to make her defense-annuling attacks hit hard, along with high Agility, a decent Block Rate, and above-average defenses to make sure she herself can take a hit and heal it off.
* LukeIMightBeYourFather: Her conversation with Mio in the Memorial Hall heavily implies that Nia might be Mio's mother (or at least, the mother of the original Mio), and that she is quite possibly the baby Nia is holding in the picture seen at the game's end. Aside from that, Nia is also shown to have trusted M (a previous version of Mio) with hiding the location of the Cloudkeep, and when Nia awakens from her slumber, her gaze lingers more on Mio than on the rest of the party.
* MakingASplash: Like in her original game, she uses water to attack and heal, which makes it even more fitting that her castle is situated above a large ocean. Her mock Aegis swords also seem to be made out of water.
* MsExposition: After being rescued, she tells the story of how Aionios and Moebius came to be.
* MythologyGag: During her recruitment cutscenes, she briefly sings the Torigoth field theme from ''[=XC2=]'' to herself. She also sometimes hums the "quest complete" jingle from the same game after winning a battle.
* NoPronunciationGuide: While almost everyone pronounces her name with a short "i" (Nee-ah), Melia uses a long "i" (Nye-ah).
* {{Polyamory}}: It's revealed at the very end that Rex married Pyra, Mythra, and her.
* PostEndGameContent: Nia can be permanently recruited to the party after defeating the FinalBoss.
* PreviousPlayerCharacterCameo: She was one of the playable party members in her own game, and returns as one of the final recruitable Heroes in this one.
* RuleOfCool: Nia now inexplicably has the ability to wield spectral Aegis sword replicas based on Pyra's and Mythra's weapons. Out-of-universe, this serves as {{fanservice}}, and in-game she only uses them for the final hit of her Talent Art.
* SealedGoodInACan: Unlike Melia, Nia chose to lock herself away and go into stasis to avoid Z's notice.
* SirSwearsALot: Despite being the Queen of Agnus, she's the same Nia as she always was and is quite the pottymouth. When she awakens in front of the party, after a few repetitions of "ow" the first thing out of her mouth is "That Bastard!"
* SuddenNameChange: Her weapon is known as the "Anima Sword" rather than the "Catalyst Scimitar", though this is most likely because it refers to her complete set of weapons (the Scimitar plus her simulated Aegis swords).
* TheWomanWearingTheQueenlyMask: PlayedForLaughs. Ironic as her ''decoy'' is the one wearing the actual mask, but Nia repeatedly tries to hide her brash personality behind a stoic, serene demeanor befitting the Queen she is. When she's recruited as a playable Hero, the party stumbles upon her dressing up in her old clothes while talking very crudely, only for her to embarrassingly return back to her more demure persona when she notices them.
-->'''Nia:''' Ahh, SCORE!! ...I mean... what... good... fortune!
* TomboyAndGirlyGirl: The brash, snarky short-haired Tomboy to Melia's refined, elegant long-haired Girly Girl.
* TomboyPrincess: Try as she might, she's still the same feisty and crude adventurer at heart despite growing up and becoming a mother and queen. She actually volunteers her services as Hero upon being recruited, in part due to wanting to feel that sense of adventure once more.
* TookALevelInKindness: Thanks to CharacterDevelopment. Nia is OlderAndWiser than before, and is considerably more mellow towards her friends and allies. While she still has sudden angry outbursts and fits of swearing, they're mostly merely used as exclamations or cries of pain and/or directed towards the villains.

!Forces and Non-Playable Characters
!!Keves
[[folder:In General]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/image_9150.png]]

The home nation of Noah, Lanz, and Eunie, Keves specializes in mechanical technology. Like Agnus, it utilizes mobile fighting vehicles known as "[[HumongousMecha Ferronises]]" in its armies, which are deployed to cover encampments of soldiers known as Colonies, which are differentiated by number.
----
* ColorMotifs: Keves soldiers wield Blades that glow blue.
* ContinuityNod:
** The emblem of the nation resembles circles-and-lines pattern from [[VideoGame/XenobladeChronicles1 the first game]]. It represented divinity, and was seen on the Monado and Zanza, the BigBad of the game.
** Classes from Keves recharge their Arts after a set number of seconds, just like Arts in ''1''.
** Keves Arts can perform the Break-Topple-Daze combo from ''1'', with the new addition of Burst at the end of the combo to give it four steps like its counterpart.
** The Levnises used by Keves resemble Faced Mechon, and Metal Face's head in particular.
* TheMagicVersusTechnologyWar: Represents the technology side of the war. They do use some ether, though.
* MeaningfulName: In Hebrew, Keves (כבש) means "lamb". [[spoiler:Much like Agnus, they're literal "lambs to the slaughter" meant to nourish the Consuls in their sick "games".]]
* PoweredArmor: Kevesi foot soldiers wear a special type of armor called a "Power Frame" that boosts their physical strength. This is necessary since the average Agnian soldier is naturally stronger than a Kevesi.
[[/folder]]

[[folder:Queen of Keves]]
!!Queen of Keves
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/melia_xeno3.png]]
->Voiced by: Shiori Katsuta (Japanese), Creator/JennaColeman (English)

->''"Henceforth, all orders are rescinded. Eliminate Ouroboros at all cost!"''

The High Entia leader of Keves. Her appearance and voice evoke [[VideoGame/XenobladeChronicles1 Melia Antiqua]].
----
* AndroidsArePeopleToo: [[spoiler:A notable aversion. Despite being sapient enough to [[BossBanter banter]] with the party and remember her previous defeat, she is treated by the human characters as more of an object or puppet and is referred to as "[[ItIsDehumanizing it]]" by multiple characters after TheReveal, particularly Crys.]]
* BackForTheDead: [[spoiler:Reappears in Noah's Hero Quest in the final chapter only to be swiftly dispatched by Consul Crys. At this point, the player and characters are aware of the major plot twists and so she's treated as a complete joke.]]
* BaitAndSwitch: Prior to her boss fight, N refers to her by name as Melia Antiqua as if it were a WhamLine. [[spoiler:Immediately after the boss fight, we see that her secret isn't that she's Melia, but that she ''isn't'' the real Melia.]]
* ContinuityNod: Her mask is similar to the Empress Mask from the first game [[spoiler:that the actual Melia wore during her initiation as Empress]].
* CoolMask: Her face is hidden behind a mask of black and white, contrasting with the Queen of Agnus' golden mask. [[spoiler:It's the one feature that distinguishes her from her organic counterpart, as Moebius apparently didn't bother with Poppi-style facial animatronics.]]
* DarkIsEvil: Wears a black dress and a sinister-looking mask [[spoiler:concealing a black robotic skeletal face]], and is loyal to the Consul and fixated on her hatred of Agnus and killing anyone who gets in her way.
* DiscOneFinalBoss: [[spoiler:Her defeat in Chapter 4 starts the story arc of awakening the true Queens and the Lost Numbers' deeper involvement in the plot.]]
* EvilDoppelganger: [[spoiler:She is an evil robotic duplicate of the real Melia Antiqua, installed by the Consul to perpetuate the war between Keves and Agnus.]]
* EvilIsHammy: Jenna Coleman's performance in the English dub oozes with sinister ham, much like Lorithia or Yumea rather than Melia, right down to having an EvilLaugh during her boss fight. [[spoiler:Because this character ''isn't'' Melia.]]
* ForgotAboutHisPowers: While Melia used to be capable of performing a wide variety of elemental summonings with all sorts of effects, the time between games has reduced her to just wind and earth in battle, and just fire in cutscenes. She's also forgotten her signature Starlight Kick, reducing her to just a blaster. [[spoiler:The copy is greatly inferior to the original in both regards: the real Melia can now summon all of her elementals with a single Art, and can still perform the kick.]]
* GenericDoomsdayVillain: Doesn't seem to have much motivation beyond preserving the status quo and killing Agnians. [[spoiler:{{Justified|trope}}, as she's a robot who probably doesn't have much motivation beyond what Moebius programmed into her.]]
* GodSaveUsFromTheQueen: Leads the forces of Keves as their queen against Agnus, and is an antagonist.
* {{Irony}}: The High Entia pride themselves on being a peaceful race, and Melia wanted to prove to [[spoiler:Zanza that they're not killing machines like he created them to be]]. However, the Queen of Keves is a High Entia who is waging war against the nation of Agnus, [[spoiler:because her personality is the opposite of the actual Melia's]].
* MagicStaff: She carries a staff resembling the Imperial Staff from the original Xenoblade.
* MercurysWings: As a High Entia, she naturally has a pair of white wings emerging from her head.
* MirrorMatch: [[spoiler:In NewGamePlus, it's possible to face her with the real Melia on your side. Fittingly, it's almost guaranteed to be a CurbStompBattle unless you deliberately level down the party.]]
* MyBelovedSmother: Acts like an abusive, overprotective and condescending mother to her subjects, referring to Noah and the party as "my beloved soldiers".
* NightmareFace: [[spoiler:Her real face is a pitch-black [[Skelebot9000 robotic]] [[SkullForAFace skull]] with purple GlowingMechanicalEyes. ''Yikes.'']]
* PreviousPlayerCharacterCameo: {{Subverted|trope}}. [[spoiler:She is a mechanical decoy of Melia Antiqua from the first ''VideoGame/XenobladeChronicles1'', who appears later in the story.]]
* PuppetKing: [[spoiler:She is presented as leading the Consuls, but in truth she is subservient to them and merely acts in accordance with their plans and to keep up the facade. An almost-literal example too, in that she's a robot; while she seems to be autonomous and sapient, nothing that she does is outside of Moebius' purview, likely because she was programmed as such.]]
* RemoteBody: [[spoiler:In the endgame, the real Melia reveals that she was using her android double to survey the party's actions while in stasis, though it's not made clear whether she had control over the robot (thus [[GoodAllAlong making her evil all an act]]) or whether she was simply observing as a "passenger", though she was able to exert enough control to cause the robot to break down when the party's lives were threatened.]]
* RidiculouslyHumanRobots: [[spoiler:To the point that she's able to fool everyone in Aionios until she breaks down. Even after her initial defeat, she continues to rule over Keves and remembers said defeat when the party runs into her again.]]
* RoboticReveal: [[spoiler:When the Queen tries to murder the party with a giant fireball, she overloads and malfunctions, revealing her robotic nature and further causing her mask to fall off to reveal her metallic skull for a face. N suspects that this was the real Melia's doing.]]
* RottenRoboticReplacement: [[spoiler:An intentional example on Moebius' part. They kidnapped the real Melia, used her as a power source to unlock Origin, and installed a loyal robot in her place.]]
* TheWorfEffect: [[spoiler:Crys destroys her in one hit during Noah's Hero Quest, and also hijacks her throne-mech.]]
[[/folder]]

[[folder:Mwamba]]
!!Mwamba
->'''Voiced by:''' Creator/YuichiIguchi (Japanese), Jason Forbes (English)\\
'''Class:''' Sharpshooter\\
'''Role:''' Attacker

A veteran soldier from Keves who fights alongside Noah's team at the beginning of the game.
----
* AmazingTechnicolorPopulation: He has two-toned gray skin similar to Lanz, suggesting possible Machina ancestry.
* CameBackWrong: [[spoiler:He's amongst the soldiers revived by Y as slaves under his control at Colony Omega. While he regains control over himself he doesn't get his memories back, though the party considers it a good thing that he at least doesn't have to remember the horrific way he died in his previous life.]]
* CrutchCharacter: He's a GuestStarPartyMember that's mainly around to provide a little extra firepower for the Keves protagonists for the first half of the first chapter, where players would be trying to figure out the hoops of the game's combat system before the two protagonist teams get together. His skills and Arts are very basic, so the player doesn't miss out on much gameplay-wise when he leaves the party.
* FriendlySniper: As a Sharpshooter, he serves as a ranged attacker while being supportive of the Keves protagonists.
* GuestStarPartyMember: He's the first Hero you get in the game, but he only stays with the party until part-way through the first chapter. Per GameplayAndStoryIntegration, that's because he doesn't have much time left.
* {{Irony}}: [[spoiler:Mwamba and Hackt -- the soldiers D killed in the first chapter that compelled the Keves and Agnus teams, respectively -- become good friends after both of them are reborn.]]
* InterfaceSpoiler: Most players will likely guess he won't survive long when they notice they can't change his equipment.
* MauveShirt: Gets a decent amount of characterization before biting it near the end of the first chapter. [[spoiler:He reappears later on as a new incarnation, but gets most of his characterization from sidequests.]]
* MentorOccupationalHazard: He is an OldSoldier who gives Noah's team some advice and gives some of the tutorials in the first chapter. He is also killed by the end of said chapter.
* OldSoldier: He's actually almost 20 years old, but since this is [[YourDaysAreNumbered Aionios]], "old" is a relative term. That said, he's one of the most experienced soldiers in Colony 9 and is one month away from the end of his lifespan.
* {{Retirony}}: With one month left before his homecoming, he decided he'd enlist on the salvaging team after one more mission fighting. He ends up being murdered by D during said final mission.
* SacrificialLamb: His murder along with Hackt's, an Agnian soldier who seemingly had a similar relationship to Mio's team, at the hands of D is one of the first things that prompts the two protagonist trios to put their differences aside and realize the true enemy in Moebius.
* WeHardlyKnewYe: He's a soon-to-be-retiring Kevesi soldier and supportive friend of Noah's team, even serving as a GuestStarPartyMember. He is killed by D along with Hackt, an Agnus soldier that apparently served a similar role to Mio's team during the first chapter. [[spoiler:However, both he and Hackt reappear later as new incarnations, and relocate to the City after Ouroboros frees them from Y's mind control.]]
* YourDaysAreNumbered: He's on his last term at the beginning of the game, having only one month left before his homecoming.
[[/folder]]


[[folder:Joran]]
!!Joran
->'''Voiced by:''' Kanon Amane (Japanese), Gerran Howell (English)

A childhood friend of Noah, Lanz and Eunie when they lived in Colony 14. He died six Terms/years before the events of the game.
----
* ChekhovsHobby: Joran had a taste for making model puppets, carving them out of wood and clay with a small knife Blade.
* GoOutWithASmile: He smiled at Lanz when he saved him before dying, as he finally felt he was useful.
* HeroicSacrifice: He pushed Lanz away from falling debris and saved him at the cost of his life.
* TheLoad: He was the weakest of his friends, a fact that bothered him deeply.
* PeekABangs: His hair hid his right eye.
* PosthumousCharacter: He's been dead for six Terms by the time of the game and so only appears in flashbacks.
* WalkingSpoiler: The fact he [[spoiler:came BackFromTheDead as Consul J and became an antagonist]] makes him this.
[[/folder]]

[[folder:Kite]]
!!Kite
->'''Voiced by:'''

A friend of Garvel's from Noah and friends' childhood. He is stationed at Colony 9 and, following the group being branded as traitors, he became Zeon's NumberTwo after the latter is named the new Commander of the Colony.
----
* HiddenDepths: He's introduced as being a former member of Garval's team (who were antagonistic bullies toward Noah's team during training), and in his position as Lieutenant of Colony 9 he remains antagonistic and is frequently causing issues. However, it's later revealed that, while he is ambitious, he also cares deeply about the people of the Colony, and his heated disagreements with Zeon are mostly a product of him feeling that [[AngerBornOfWorry Zeon isn't protecting them adequately]]. It's also shown that he's extremely popular with the rank-and-file of Colony 9, and is actually a decent leader when he isn't being hotheaded. In the end, he and Zeon manage to make peace with each other after Zeon tries interacting with him more like an equal and not as just a commander and subordinate.
* ShipTease: He has a blatant crush on Juniper in Zeon's Hero Quest despite them being Agnian, perceiving them with sparkles and not understanding why he's suddenly getting pains in his chest looking at them.
* TheStarscream: A lighter version than most. Kite makes his disagreements with Zeon's leadership quite vocal and even outright states at the end of Zeon's Hero Quest that he will become the new Commander. Zeon isn't really bothered about this like others in his position would since they're both worried about the colony and would gladly step down if the colony's people wished him to do so; on top of that, Zeon earns Kite's respect by the end of his second Hero Quest while Zeon himself learns how to treat him as a comrade rather than as a subordinate.
* WeAreStrugglingTogether: He and Zeon butt heads amid Colony 9's supply shortage. While Zeon has been living up to his new post after his Hero Quest is completed, Kite still takes issues with decisions, such as RobbingTheDead from Everblight Fields and prefers the more by-the-book approach, even though such plans are much harder to execute now that Colony 9 is cut off from the Castle. By the end of Zeon's second Hero Quest, he comes to trust in Zeon's methods.
* WhatIsThisThingYouCallLove: After meeting Juniper for the first time, he doesn't understand why he's suddenly nervous or the feeling he's getting in his chest while looking at them.
[[/folder]]

[[folder:Bolearis]]
!!Bolearis
->'''Voiced by:''' Creator/MasakazuMorita (Japanese), Creator/SeanTeale (English)

The lieutenant of Ethel and second in command of Colony 4.
----
* MellowFellow: In contrast to Ethel, Bolearis is very casual and relaxed regardless of the situation and can even soften up Ethel at bit with his personality.
* NoodleIncident: When the party finds him in Chapter 4, he's horribly beaten up and on the run from Keves, leading them to believe he was attacked for his betrayal. In reality, he lost his way in the dark and fell of a cliff.
* NumberTwo: Acts as Ethel's trusted confidant and friend who helps with managing the colony. [[spoiler:He becomes the commander after Ethel's death in chapter 4]].
* RedOniBlueOni: The blue to Ethel's red, as he is much more relaxed than his commander and doesn't have her enthusiasm for battle.
[[/folder]]

[[folder:Garvel, Layla, & Hoope]]
!!Garvel, Layla, and Hoope

Three Kevesi soldiers that formed a four-man squad with Kite that antagonized Noah and his friends in their early terms in flashbacks.
----
* ArrogantKungFuGuy: All members show degrees of this, Garvel in particular as he has shown to be incredibly skilled with his Blade and doesn't hesistate to show off how great he think he is. It gets to the point that he initiates an attack on Noah after mocking his supposed inability to draw his Blade and gets royally ticked off when Noah easily gets the upper hand at first. [[spoiler:His skills in battle are the reason that Consul H chose him to lead a team of newly reborn soldiers of Colony 8 after he, Layla, and Hoope were reborn]].
* BackFromTheDead: [[spoiler:Despite having been with the same term as Noah and the others growing up, they are seen again as early termers later in the game in a side mission due to having been killed and reborn as part of Consul H's experiment of creating elite soldiers from the cradle]].
* TheBully: They antagonized Noah and his friends both in and outside of the Trial with Garvel being the aggressor, mocking Noah for still using a training sword and Joran for his weaknesses.
* {{Foreshadowing}}: After a confrontation with Garvel's gang, Lanz remarks that guys like him are the first to snuff it in battle. However, while Garvel and his squad were shown to have beaten Noah and his friends in the mock battle trials, [[spoiler:we later learn that after plenty of chapters in with no mention of them in the present, they were sent to Colony 8, which was said to have been wiped out]].
* TheSocialDarwinist: They had shades of this back before being reborn, but [[spoiler:after being brought back to serve under Consul H, they fully subscribe to the ideal, Garvel especially. Even to the point where Garvel asks the party to ''[[KickTheDog kill]]'' Lyla and Hoope so he could take their life for himself on the argument that the weak don't deserve to live.]]
* TookALevelInKindness: [[spoiler:After being saved from Consul H, the trio is sent from Colony 4 to Colony 9, which is not only the Kevesi Ouroboro's current home colony, but where the trio goes from being soldiers to potato farmers under the direction of leaders that used to be childhood friends with their previous incarnations. It takes time along the story, but they all find themselves much happier farming potatoes instead of fighting all the time, especially with Garvel, who states that he now looks up to Kite as a role model in leadership]]. It's a bit ironic, considering early flashbacks showed a young Kite used to follow his lead, such as during the Trial.
* WreckedWeapon: In a flashback of Noah explaining his sword to Mio, Garvel aggressively attacks and destroys Noah's training sword in a fit of arrogance.

[[/folder]]

!!Agnus
[[folder:In General]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/image_9816.png]]

The home nation of Mio, Sena, and Taion, Agnus specializes in using Ether in its technology and military. Like Keves, its military employs mobile weapons called "[[HumongousMecha Ferronis]]", some of which are home to groups of soldiers called Colonies, which are differentiated by letters of the Greek alphabet.
----
* AmbiguouslyHuman: Some characters from Agnus are shown to have blue glowing markings on their bodies, and in the case of Nimue, sports a horn with ice coating her arms. They're implied to be Blades, given that Mio and Sena have what appear to be glowing Core Crystals on their chests.
* ColorMotifs: Agnus soldiers wield Blades that glow green.
* ContinuityNod:
** The emblem of the nation resembles a stylized Core Crystal from ''VideoGame/XenobladeChronicles2''.
** Characters from Agnus recharge their Arts after performing a certain number of auto-attacks, with a bonus for cancelling their auto-attacks into their Arts, just like characters did in ''2''.
** Agnian Arts can perform the Break-Topple-Launch-Smash combo from ''2''.
** Agnus machines use energy blades and angelic motifs, much like the Artifices did.
** Their more formal white, black, and red clothing brings to mind the kingdom of Torna.
* LightIsNotGood: They have [[HumongousMecha large mechs]] that are capable of light-based attacks [[spoiler:which the Queen of Agnus uses her throne as a mech during her boss fight.]]
* TheMagicVersusTechnologyWar: Represents the magic side of the war, massively relying on ether. Downplayed, though, as the nation uses {{Magitek}} instead of pure magic.
* MeaningfulName: In Latin, Agnus means "lamb". [[spoiler:Like Keves, they're literal "lambs to the slaughter" and no more than nourishment for the Consuls in their sick "games".]]
* {{Pun}}: The term to refer to something that involves Agnus such as an attack from them is "[[https://twitter.com/NintendoAmerica/status/1522678213654233097 Agnian]]." Agnus is led by the Queen of Agnus who has a resemblance to [[VideoGame/XenobladeChronicles2 Nia]], [[spoiler:who is the true Agnian Queen]].

[[folder:Queen of Agnus]]
!!Queen of Agnus
[[quoteright:275:https://static.tvtropes.org/pmwiki/pub/images/nia_xeno3.png]]

->'''Voiced by:''' Creator/HitomiOhwada (Japanese), Catrin Mai-Huw (English)\\

->''"They must be erased without a trace!"''

The leader of Agnus. She appears to have a Flesh Eater Core Crystal in her chest. Her appearance and voice evoke [[VideoGame/XenobladeChronicles2 Nia]].
----
* AdvertisedExtra: Despite being hyped up as one of the main threats, her role is even more marginal than her Kevesi counterpart, only making a single very short appearance before Chapter 5. [[spoiler:The ''real'' Nia, on the other hand, plays a more important role and is even a postgame Hero.]]
* AmbiguouslyHuman: [[spoiler:Unlike the false Kevesi Queen, who is directly shown to be a robot, the nature of the false Agnian Queen is left ambiguous. The game goes out of its way to avoid showing whether or not she's a machine (particularly after her defeat), down to the characters referring to her in the vaguest terms possible. Her voice isn't heavily filtered despite wearing a mask just like her Kevesian counterpart, and she screams when X takes control of her. This suggests that she may be a human impersonator rather than a robot like with the false Melia.]]
* CatGirl: She has cat ears like Mio, further hinting at her implied secret identity.
* CoolMask: She wears a golden mask with red highlights, which contrasts with the Queen of Keves' monochrome mask. [[spoiler:It's the one feature that distinguishes her from her organic counterpart, as Moebius apparently didn't bother with Poppi-style facial animatronics.]]
* EvilDoppelganger: [[spoiler:Like with the false Kevesi Queen, she is a decoy of the real Nia that serves the Consul.]]
* GodSaveUsFromTheQueen: She is the leader of Agnus in the war against Keves, and an antagonist.
* HopeCrusher: They have prisoners killed during a solar eclipse at a place directly called "Hope's Rest" in order to crush thoughts of rebellion.
* HumongousMecha: [[spoiler:Pilots her throne as a mech during her boss fight. The fake Queen of Keves has one too, but it's used by Crys instead.]]
* {{Irony}}: [[spoiler:As the real Nia is a Flesh Eater, this version of her being a synthetic duplicate (robotic, if Melia's is anything to go by) makes her an "Artificial Blade" in the most literal sense possible.]]
* LightIsNotGood: [[spoiler:The Queen of Agnus uses her throne as a mech during her boss fight exhibiting light-based attacks.]]
* MirrorMatch: [[spoiler:In NewGamePlus, it's possible to face her with the real Nia on your side. While the decoy's fighting style is completely different from the real deal, it's still likely to be a CurbStompBattle given the requirements.]]
* PuppetKing: [[spoiler:Just like the fake Queen of Keves, she is presented as the highest authority in Agnus but in truth she is completely obedient to the Consuls.]]
* WeHardlyKnewYe: [[spoiler:Unlike the false Queen of Keves, who at least got some characterization as a GenericDoomsdayVillain and a surprise endgame reappearance, the false Queen of Agnus gets one command, one speech (largely relegated to background noise), and one boss fight before disappearing for the rest of the game.]]
[[/folder]]

[[folder:Nimue]]
!!Nimue
->'''Voiced by:''' Yukiyo Fuji (Japanese), Maya-Nika Bewley (English)\\
One of Taion's old friends and former commanding officers. Taion believes himself to have had a hand in her death and fears Isurd's feelings towards the act.
----
* BackFromTheDead: [[spoiler:Like all Kevesi and Agnian soldiers, she turns out to be completely fine during Taion's Hero Quest, albeit as a new incarnation.]]
* HeroicSacrifice: She sacrificed her life to save Taion and two other Agnian soldiers from an overwhelming Kevesi force.
* TheMentor: She was the one who taught Taion how to use his Mondo.
[[/folder]]

[[folder:Seeker]]
!!Seeker

A suspicious figure leading the efforts to restore Agnus Castle and work with the Lost Numbers.
----
* GoodAllAlong: Despite the group's initial misgivings, he was doing the right thing all along and genuine in his efforts to help.
[[/folder]]

[[folder:The Three Fiends]]
!!The Three Fiends (Tohma, Jhodor and Xera)

Three Agnian prisoners in the Castle accused of horrible crimes against their colonies.
----
* GoodAllAlong: Like Seeker, they only had good intentions all along and were only working against their Consul, who fabricated the accusations against them in the first place.
[[/folder]]

[[folder:Ragzy]]
!!Ragzy

The leader of an insurgent group of Agnian soldiers who dislike the new regime and want to return to hostilities with Keves.
----
* BossBattle: He is fought in a Levnis during a series of sidequests.
* WeWantOurJerkBack: He actively prefers hostility over peace and accepted the fake Queen over the real one.
[[/folder]]

[[folder:Tirkin Family]]
!!Jumbo Tirkin, Mini Tirkin and Micro Tirkin

A family of Tirkins that appear during Ghondor's ascension quest, consisting of a very large father Tirkin and his two "Tirklets". After their father passes on, the two Tirklets work with the Lost Numbers and Agnians at Agnus Castle.
----
* FunetikAksent: All three of them retain the usual Tirkin {{Verbal Tic}}s of YouNoTakeCandle, misspelling/shortening words and replacing the hard "c" sound with "k". Jumbo Tirkin is also voiced with a thick Cockney accent, like others of his species.
* HeroicSacrifice: Jumbo Tirkin suffers fatal wounds after helping the party fight off invading soldiers.
* NonMaliciousMonster: Jumbo Tirkin attacks Kevesi and Agnian soldiers, but only because they attack him first.
* YouNoTakeCandle: Just like Nopon, their grammar is highly simplified but is also combined with other quirks.
[[/folder]]

!!Lost Numbers

[[folder:In General]]

The inhabitants of the City, a settlement hidden within the former Mechonis sword, the Great Sword. They act as the primary resistance against the Consuls.
----
* BystanderSyndrome: Monica mentions that there are inhabitants of the City that couldn't care less about the suffering of the rest of Aionios as long as it doesn't affect them personally. Justified to an extent by how long the City has been fighting without any real progress, and by Moebius projecting images of mass executions of their captured loved ones each year.
* FeudingFamilies: Despite being the sole bastion of "regular" humanity, the City still managed to split itself into the Six Families, that have often contrasting viewpoints and constantly bicker among each other. There's even a City sidequest that's literally ''Theatre/RomeoAndJuliet'', just to drive the point home further.
* KlingonScientistsGetNoRespect: As the City is essentially a paramilitary commune, there's a noted disdain towards people with pursuits that seemingly don't help the war effort:
** Shania's mother considered her love of painting worthless because it wasn't making her better at fighting or surpassing the Vandhams.
** In one sidequest, the party meets a juggler who laments the fact that since he chose not to be a soldier (The Lost Numbers are a strictly volunteer unit), his juggling is not seen as being of any use despite his skill and the fact that it raises morale amongst the City's inhabitants.
* LaResistance: They're a resistance movement against the Consuls.
* MobileCity: [[spoiler:The City is actually a giant Ferronis capable of moving, though this is a secret only shared with the most trustworthy members of the group.]]
* MorphWeapon: As descendants of the Ouroboros, they share the ability to transform their Blades into any shape, though they normally stick with one as they lack Ouroboros' ability to instantly pick up Blade skills by switching classes.
* OurHumansAreDifferent: The only humans in the setting whose lifespans are the same as humans on Earth, contrasting the Agnians and Kevesi who only live about 10 years at most once they leave their pods.
* UsedFuture: Compared to the sleeker and more fantastic Agnus and Keves, Lost Numbers tech tends to have a rougher, more grounded look.
* WeAreStrugglingTogether: Reaching the City is the party's first primary objective over the course of the game. While they're initially rendered speechless by the number of people and the concept of living a normal, free life, they also learn that the City is far from perfect and not quite the haven they initially believed due to generations of political in-fighting, radical factions within each group, and a barely-there sense of unity only thanks to the respect for the Founders. Several side quests involve and further explore its self-contained world and how it also has to learn to confront change when it inevitably arrives.
[[/folder]]

[[folder:The Founders]]
After the destruction of the original City, four survivors became Ouroboros alongside a Kevesi and Agnian and sought for a place to build a new City. The six--Rhodes, Cassini, Vandham, Doyle, Reid, and Ortiz--founded the current City the Lost Numbers reside in today. In addition to specific personal contributions, the six Founders are the progenitors of the Six Families, who remain powerful and influential to this day.
----
* BackFromTheBrink: Consul N razed the original City at Hope's Rest, leaving four known survivors. Today, the City boasts the largest population of any settlement on Aionios, dwarfing even that of the Castles, and is physically larger in area than several Colonies put together. It's also the only place on the planet where people live past 10.
* FamedInStory: The Lost Numbers work to honour their legacy, as they prevented an outright Moebius victory by surviving, and then became Ouroboros to fight off more Consuls and establish a new city.
* HeroicLineage: Guernica, Monica, and Ghondor Vandham are descendants of the Founder Vandham.
* HistoryRepeats: Ortiz and Rhodes were Kevesi and Agnian soldiers respectively who were poised to kill each other until a chance encounter with the other Founders.
* MythologyGag: Some of the Founders share a resemblance with characters from the previous games:
** Founder Ortiz looks remarkably similar to Shulk and shared his mastery of engineering, having built his own weapon, and is responsible for the mechanical systems in the City.
** Founder Reid's mentor was a composed but fierce warrior who used a bright red sword in the battle against Moebius, and continued to fight even after losing his right arm, much like Dunban while the statue's physical appearance marks the statue as a older Shulk.
** The Cassini Founder's statue also shows a mentor, one who used two swords at once. Looking at the collar and hairstyle, and the rough but passionate attitude described, marks the statue as an older Rex.
** Founder Vandham has a ponytail and is noted to fight with his fists, looking very much like Fei Fong Wong.
* PrecursorHeroes: They founded the second (current) City after the original was destroyed by N.
* SiblingTeam: Founder Vandham and Doyle were said to have been brother and sister, and fought together to bring Ouroboros to completion.
* ShroudedInMyth:
** Not much is known about the Founders outside of their names and that they re-founded the City. Not even their statues are much help, as two of the Founders chose to honour their mentors rather than make statues of themselves.
** The seventh founder is the most enigmatic, as the only evidence of their existence is that the original plans for Memorial Hall meant to include them where the Ouroboros Stone Cage now stands. Historians speculate that the seventh Founder chose to remain hidden.
** No one knows what happened to Founder Doyle between N destroying the first city and finding the other Founders.
** After reestablishing the City, Founder Vandham left and was never seen again. His descendants arrived to the new City centuries later.
** Rhodes and Ortiz lived into their 80s despite being part of the Flame Clock system, which should have killed them at the end of their 10th term.
* TwoGirlsToATeam: Averted and inverted. The Memorial Hall pays tribute to six Founders with four male statues and two female statues. However, the statues for Rhodes and Cassini depict their male mentors instead of the Founders themselves, which means that the Founders were a team of four women and two men.

[[folder:Guernica Vandham]]
!!Guernica Vandham
[[quoteright:225:https://static.tvtropes.org/pmwiki/pub/images/xc3_guernica_vandham.png]]
->'''Voiced by:''' Creator/TesshoGenda (Japanese), Simon Thorp (English)

->''"The only thing that can change all this, is the will of Ouroboros. You kids, and you alone."''

A mysterious man, who tells the party about the "true enemy".
----
* AscendedExtra: Played with. In contrast to the previous Vandhams in the ''Xenoblade Chronicles'' series, Guernica is the one who gets the ball rolling at the start of the game, informing the main characters that there's someone pulling the strings for both sides and giving them their Ouroboros powers. On the other hand, [[AdvertisedExtra despite what pre-release materials and the trailers suggested, this Vandham is killed off minutes after he's introduced.]]
* TheBigGuy: He's as big and muscular as Lanz, and he has no trouble keeping Mio and Noah pinned to the ground while getting their groups to stop fighting.
* HeroicLineage: He's a descendent of the Founder Vandham, one of the original Ouroboros and founders of the Lost Numbers.
* IdenticalStranger: Beyond just continuing the series' RecurringElement of being someone named Vandham, he looks and sounds a lot like Vandham from ''Xenoblade Chronicles 2'', down to having the same voice actors in English and Japanese.
* MadeOfIron: Despite getting a hole shot clean through his chest, he's still able to climb into his ship, pilot it into attacking the Moebius, being thrown around, and convince the party to stop their fighting while delivering exposition before dying. While he still dies, the wound should have killed him ''instantly'' yet he's able to survive for several more minutes at least before passing away.
* MeaningfulName: His first name, Guernica, is the name of a Spanish city that was blasted into rubble by the Nazi Luftwaffe during the Spanish Civil War, in what effectively was a dry run for World War II. The Spanish Republican Government commissioned a painting from Pablo Picasso to immortalise the event, which became a world-famous allegory for the madness and meaninglessness of war.
* MrExposition: He tells the party about the "real enemy".
* MythologyGag: Not only does he look and sound like ''[=XC2=]'' Vandham, his comrades are even named Yew and Zuo and look similar to their Alrest counterparts as well. He also has Vandham as a surname similar to Commander Jack Vandham from ''VideoGame/XenobladeChroniclesX''.
* NiceGuy: In the limited amount of time that we see him, while he's forced to rough Noah and Mio up a bit to keep them from fighting, he comes off as a very affable guy.
* OldSoldier: Vandham tells the party that he's 60 or in their words having lived for more than six cycles, but he's still an active fighter.
* ParentsAsPeople: Monica mentions that due to his duties to the City he was so busy that she knew him more as leader of the City than as her parent growing up, though she still loved him all the same.
* PosthumousCharacter: The party only learns much about him long after he dies at the beginning of the game.
* RecurringElement: Carries on the series tradition of having one "Vandham" per game. [[spoiler:However, there is an entire family of the Vandham this time around]].
* SmallRoleBigImpact: Twofold. Despite dying within an hour after his introduction, Vandham's last act triggers the cast's ability to become Ouroboros while revealing the existence of a hidden faction steering the war. There's also the fact that he is, by his own admission, sixty years old; given how it was established almost immediately within the first hour of the game that everyone in Agnus and Keves only has a life span of ten years and looks to be in their late teens at best to early twenties at oldest, this clues the player in that not everything is at it first seems.
* SpannerInTheWorks: The Ouroboros Stone in his possession and him just being there when Noah and Mio's respective allies clash throws a major wrench in the Consuls' "games".
* SuperEmpowering: Uses the Ouroboros Stone during the protagonists' battle with D, causing all six to become Ouroboros themselves and give them the upper hand against D.
* TheyKilledKennyAgain: True to the tradition started with Xenoblade Chronicles 2, Vandham ends up getting killed again.
* WeHardlyKnewYe: He dies in the very same chapter he's introduced in. Any other information about him comes long after his death.
* XMarksTheHero: Has an X-shaped scar on his face, and he's a hero.
[[/folder]]

[[folder:Shania '''(UNMARKED SPOILERS)''']]
!!Shania Reid
->'''Voiced by:''' Creator/HarukaTerui (Japanese), Louise Stewart (English)\\

One of Monica's assistants, she helps lead the party through the City and assists them with their mission to free Ghondor.
----
* AbusiveParents: Her father was fine, actively encouraging her to pursue her dream of being a painter. Her mother on the other hand viewed her as a "pathetic child" and saw painting as worthless for their family image in a world of endless war, and when Shania's father and sister died, her mother's true colors came out and persisted even after Shania dies a second time. When the truth comes out, the only thing that stops Sena and Ghondor from beating Shania's mother bloody is because it looks like ''Monica'' is going to do it.
* AlasPoorVillain:
** Both Ghondor and Sena are deeply saddened by both of her deaths despite her betrayal of the City in general and them in particular, and almost attack Shania's mother when she disrespects her in front of the memorial stone before Monica interrupts.
** After Sena's sidequest is completed, Playne mentions that he noticed Shania being constantly compared to her elder sister Titania and the toll it was having, but was told by others to stay out of it, and laments that he didn't try to do more. In the same vein, Timna describes Shania as "the pitiable child of a downtrodden house", and wishes that she and Monica had noticed what was going on earlier and done something about it.
* BetterToDieThanBeKilled: When cornered in the aftermath of Mio's Homecoming ceremony, rather than surrender or resist, Shania simply [[DrivenToSuicide commits suicide]]. Subverted in that she knew she would be reborn after having a Flame Clock installed within her.
* ChildhoodFriends: She and Ghondor have known each other from when they were babies.
* ColorCodedTimestop: Anyone frozen by Shania's power is surrounded by a red haze of Moebius energy.
* DaddysGirl: In flashbacks during Sena's Hero Quest, Shania was shown to have a better relationship with her late father, who encourages her to be a painter since it's what makes her happy, than with her living abusive mother.
* DiedInYourArmsTonight: Dies for the second time in Ghondor's arms after fighting the party as a Moebius.
* DeathEqualsRedemption: Shania realizes the error of her ways in the midst of dying for the second time after being finished off by Ghondor.
* DespairEventHorizon: Shania's motivation for betraying everyone to Moebius apart from jealousy towards Ghondor is her belief that the constant stasis of Aionios is preferable to a chaotic world where those who can't live in peace (Who she describes as those without power, implicitly including herself) suffer. As far as she was concerned her current life was a wash, and getting only that "one chance" was the worst fate possible, leading to her clinging to the promise of getting another life as a Moebius.
* {{Expy}}: To Hammer from ''VideoGame/{{Xenogears}}'', being an ally to the heroes who betrays them to the villains for power out of a major sense of inadequacy. She similarly shares Hammer's color scheme between her green outfit and her brown hair that resembles his fur.
* {{Foil}}: To Sena. Both girls were considered outcasts in their youth but eventually befriended and latched on to a girl more popular and talented than them, and their resulting inferiority complexes drove them to emulate their idols in any way they could. The only difference is that Sena eventually grew out of it and decided to embrace her own personal qualities, while Shania couldn't let go of the past and became obsessed with surpassing Ghondor.
* GenocideFromTheInside: She, an inhabitant of the City, tries to kill everyone in it on two separate occasions (though even with the City at her mercy she notably doesn't kill anyone immediately, instead opting to wait for the party to fight her).
* GoOutWithASmile: After she and Ghondor have a heart to heart during the former's final moments after attacking as Moebius S, she cracks a smile before dying at peace.
* GoryDiscretionShot: Her suicide is seen from her own point of view after pulling the trigger, and the following scene has her body face down, preventing the player from seeing the entry wound.
* GreenEyedMonster: Apart from literally having green eyes, she was deeply envious of Ghondor as Shania's talent as a painter was no good in combat. Even after coming back from the dead and trying to destroy the City, her primary motivation seems to be more based around proving herself better than Ghondor than anything else, with the City's destruction as a secondary goal, as she could've easily killed everyone before the party plus Ghondor got there, but instead waits for them to get there. During the battle proper she calls out Ghondor specifically while attacking.
* HateSink: Not Shania herself (especially after Sena's sidequest), but her mother, who was an abusive parent whose callousness even causes Sena and Ghondor to almost beat her up when she calls Shania a "pathetic child" while they're mourning her.
* HeroicLineage: She's a descendant of Reid, one of the City's Founders.
* IJustWantToBeBadass: One of her main issues growing up was her desire to impress her mother and live up to the Reid name by joining the Ouroboros program despite the fact that she was ill-suited to be a soldier. She still managed to come in 8th out of 100 applicants to become an Ouroboros, but since there can only be 6 at a time, her mother regarded this as no different than coming in last.
* LethalHarmlessPowers: Shania mentions that her powers allows her to not only freeze people, but freeze the air around them, leaving them to suffocate, though she doesn't bother doing a demonstration.
* KickTheDog: After she betrays the party and they spend a month in prison as Mio's Homecoming approaches, she visits them at least once mainly to rub their defeat in their faces and gloat about killing herself to become a Moebius.
* MadArtist: After coming back as a Moebius, she freezes the city's inhabitants in time so that they can serve as her "art", and makes numerous painting metaphors with Ghondor before attacking.
* MegaTwintails: Her pigtails turn into gigantic tentacles in Moebius form.
* TheMole: She's been working with Moebius the whole time and giving them intel on the Lost Numbers.
* MorphicResonance: Moebius S has tentacles coming from her head where Shania's pigtails are in human form.
* MotiveRant: Prior to her first death, she rants about feeling alone and unwanted all her life and the unfairness of the world before proceeding to take her own life with her pistol before Ghondor and Sena can stop her.
-->'''Shania:''' It's your eyes, that look! You've always looked at me that way! Why did it have to be like this? Why is it always me?! Standing here on my own?
-->'''Ghondor:''' Shania...
-->'''Shania:''' Ah ha ha ha... I've had it... I've had it up to ''here!'' ''[pulls out her pistol]''
* MyDeathIsOnlyTheBeginning: Says the trope name almost verbatim before shooting herself in the head, and it proves true when she revives as a Moebius for Sena's sidequest.
-->'''Ghondor:''' Shania! Drop it! This isn't what I meant by "done"!
-->'''Shania:''' Don't misunderstand... This is... THIS IS THE BEGINNIIIIIING!!
* NotSoDifferentRemark: After Sena shares her backstory with her, Shania remarks that they're the same, in the sense of always following behind the person they admire/want to be like.
* OneWingedAngel: Takes on her Moebius form for the battle with the party.
* PsychoticSmirk: After being revealed to be a mole for Moebius, her main expression apart from rage is an intensely satisfied smirk at the thought of becoming a Moebius.
* ShutUpKirk: Noah and Sena try to talk her down before fighting her, but she rebuffs all their attempts.
* StealthExpert: She's been tailing the party since at least their infiltration of Castle Keves without their knowledge until they're directly introduced in Swordsmarch, an impressive feat when you consider Mio's enhanced hearing.
* TragicKeepsake: A variation, her pistol Blade form belongs to her deceased elder sister Titania, which makes the fact that she kills herself with it doubly messed up.
* TragicVillain: The loss of her father and sister left her alone with her demeaning and callous mother, who proceeded to tear her down emotionally and mentally for not outdoing House Vandham. The result was that her self-esteem plummeted to the point where she tried copying everything Ghondor did, and eventually turned to Moebius after experiencing so much rejection.
* TranshumanTreachery: After she kills herself, she comes back as Moebius S and tries to destroy the City in Sena's sidequest.
* WellDoneSonGuy: Everything she did growing up was to obtain her mother's approval, only to fail at it despite what should have been impressive results.
* WalkingSpoiler: Knowing too much about her means knowing that she's a traitor among the Lost Numbers.
* WhereIWasBornAndRazed: Attempts to have the City destroyed with Castle Agnus' Annihilator, and tries again for Sena's sidequest.
* YouAreBetterThanYouThinkYouAre: Ghondor tells her this as Shania dies in her arms, as Ghondor primarily remembered Shania's talent for painting and how her father encouraged her to follow it, knowing how much she loved it.
* ViolentGlaswegian: Zigzagged, as she's got a Scottish accent in the English dub and Moebius S can fight, but Shania's main conflict growing up was that she was ill-suited to being a soldier, Ghondor noting that she can barely throw a punch (though in the context of her being ill-suited to a fist weapon and better with a ranged weapon, she still gained a high rank in military tests despite her being mentally not suited to the lifestyle).

!Moebius/The Consuls
[[folder:In General]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/xc3_consul.png]]

A mysterious group pulling the strings behind the Keves/Agnus war.
----
* AlphabeticalThemeNaming: There is a Moebius for almost every letter of the Latin alphabet. The only letter for the Moebius theme naming whom doesn't appear in the base game (barring DownloadableContent) is A.
* AlwaysChaoticEvil: Justified; Moebius are deliberately screened for membership before they become Moebius, meaning that one has to already be someone who would already turn their back on humanity to preserve the ForeverWar at all costs for whatever reason before they get that power. [[spoiler:As shown by [[EvilFormerFriend J]], awakening to all their PastLifeMemories sends those who still had qualms [[DespairEventHorizon over the deep end]], with the realization of how inescapable the war is causing them to draw into themselves and come to see strength as the only measure of worth. It ends up being subverted as the game goes on - Moebius aren't inherently evil, their hedonism and power means they usually just naturally end up becoming psychopathic monsters as a result. Triton found other ways to live out his immortality that were much less destructive, travelling the world and seas, I, despite her actions is implied to have honestly cared for Fiona, and M didn't even want to be a Moebius in the first place.]]
* ArcSymbol: The lemniscate, [[{{Infinite}} the "sideways eight" symbol for infinity]], is associated with them. The lemniscate happens to be one form of a shape known as a Möbius strip.
* BadBoss: Most of them treat their Colony commanders like dirt, no matter how many times they watch their companions doing the same lead to a MistreatmentInducedBetrayal. The Ouroboros make so much progress on freeing Colonies from the control of the Consuls almost entirely because they can't stop doing this.
* BigRedDevil: In their Moebius form, they become giant monsters with skin in the same bright red color as the armor they wear in their human Consul form.
* BroughtToYouByTheLetterS: Most of the Consuls have an element of their armor that reflects their OneLetterName, such as X having an X-shaped helmet.
* TheCaligula: [[spoiler:Given that the Queens are actually just duplicates serving as their mouthpieces]], they are the ones who really rule Aionios. Their rule involves mandating 10-year lifespans, perpetuating a ForeverWar where ChildSoldiers kill each other for the Consuls' entertainment, and occasionally feeding on the higher-ranking Colonies' lifeforces for nourishment. According to [[spoiler:Ashera]], at the very beginning prior to the Queen system being set up, the Consuls would just personally execute soldiers who'd manage to make 10 years, a death described as far more humiliating than any suffered at an enemy's Blade.
* DarkIsEvil: Their powers are associated with shadows and [[PurpleIsPowerful purple]] energy.
* DeathActivatedSuperpower: [[spoiler:In order for someone to attain Moebius powers, they have to die first.]]
* EvilCounterpart: Like the main characters, members of Moebius can transform, but they don't need to Interlink in order to do so -- but to do so requires becoming a LifeDrinker. [[spoiler:Which isn't to say they ''can't'' Interlink.]]
* FaceDeathWithDespair: Upon defeat, most of them spend their final moments screaming that they don't want to die and/or begging Z to save them.
* FatalFlaw:
** The inability to change. As they are obsessed with living in an "eternal now", most of them are unable to go beyond being hedonistic {{Life Drinker}}s even as the heroes liberate colonies under their ([[BadBoss often abusive]]) control and defeat many of its members.
** Their hedonism also frequently leads to their deaths. The "eternal now" that Moebius cling to is so boring (their home base being perceived by them as a simple dark room thanks to Z) that most of them obsess over gaining some form of stimulation by manipulating human lives, often just for the thrill of it enacting plans or willingly putting themselves into situations that end up getting them killed by Ouroboros (this in spite of the fact that the "change" of death is the thing most of them fear most).
* ForTheEvulz: Most of their evil actions are justified by them as being nothing more than a game to entertain themselves.
* GoMadFromTheRevelation: J reveals that [[spoiler:when a person is elevated to Moebius, they immediately regain all of the memories of their past selves at once, which explains why many of their members have gone insane despite having previously been regular humans]].
* HeartDrive: Moebius members have a Core located where their heart would be, leading to their deaths if someone manages to break it.
* TheHedonist: The main motive they have beyond eradicating Ouroboros, their natural adversaries, is finding ways to entertain themselves. [[spoiler:This is part of the pitch Z gives to potential members, because as immortals, the only thing they need to do is stave off boredom, allowing them to live in an "eternal now" where they don't need to give a rip about the future or the past.]]
* ItAmusedMe: [[spoiler:Z doesn't really have any particular standards for who he inducts into Moebius, other than whether the choice amuses him or not.]]
* LifeDrinker: Moebius are capable of absorbing the life-force of others. They can do this by sucking it up directly from those closest to them or by taking it from a nearby Flame Clock.
* LightIsNotGood: Downplayed, as their powers are darkness-themed, but their abilities are directly stated to be based on the concept of living things -- it just so happens that NatureIsNotNice, hence their LifeDrinker status due to the concept of predation.
* MeaningfulName:
** A Consul was the name of the heads of state of the Roman Republic, alluding to their role as TheManBehindTheMan for both Keves and Agnus.
** Moebius, their true name and their transformation power, likely refers to the Möbius strip, a 3-dimensional object that has only one uninterrupted side. This is a direct contrast with Ouroboros, which is also named after a shape forming an uninterrupted circle.
* MonsterOfTheWeek: While some of Moebius get more screentime to themselves and serve as primary villains, a fair number of them only serve to be the final boss of a Hero's recruitment quest.
* MundaneUtility: A rather twisted version. They sometimes use their SinisterSurveillance to watch battles in the ForeverWar to [[NoSympathy snark on particularly cliche lines]] and take wagers on the outcome.
* NoBodyLeftBehind: Upon dying, they turn into blue motes akin to those released by dying Kevesian and Agnian soldiers.
* NotSoOmniscientCouncilOfBickering: About the only commonality they share is their desire to live forever; they regularly snipe at each other, compete, and express NoSympathy for dead members.
* OlderThanTheyLook: It's implied that a Consul's body is frozen at the exact moment they become a Moebius, so despite the youthful visage of some they're actually far older than they appear.
* TheOmniscientCouncilOfVagueness: Their introduction in the Direct involves them meeting in a shadowy figure in face-hiding uniforms to make ominous statements about fate, revealing they are manipulating the war for unknown but definitely sinister reasons.
* OneLetterName: All members are referred to as a single letter, like "D", "P", or "N". [[spoiler:These are the initials of their original names (at least for the ones whose original identities are revealed).]]
* OneWingedAngel: Each of them can transform into a more monstrous form called Moebius. [[spoiler:They can also interlink with one another to become even more powerful.]]
* OptionalBoss: A good number of Moebius are exclusive to Hero Quests.
* OrderIsNotGood: They are the protectors of the world, as opposed to Ouroboros, the enemies of the world. Said world is [[CrapsackWorld an utter nightmare]], so Moebius are AlwaysChaoticEvil.
* OurVampiresAreDifferent: They're shapeshifting monsters who were once human [[spoiler:and died]] who feed on life force.
* RedAndBlackAndEvilAllOver: They wear shiny red armor with black secondary pieces in their human Consul form while their monstrous Moebius forms have their skin in the same colors. As for the evil part, they are the true villains behind everything that's going on in Aionios.
* RedEyesTakeWarning: When in Moebius form the Consuls have bright red eyes, and they're all dangerous villains.
* SigilSpam: Lemniscates show up everywhere they have influence.
* SinisterSurveillance: They can see events on Aionios through a movie theater. The main reason members of the Lost Numbers wear eyepatches over their Ouroboros eye is because they emit a radio signal that Moebius can detect.
* SmugSnake: Most Consuls in a nutshell as they start off confident in their superiority, and then suffer {{Villainous Breakdown}}s as the heroes gain the upper hand.
* TinTyrant: Moebius are an antagonistic force who are all dressed in intimidating metallic armor, and it's noted many times they're the real power behind the war.
* TwoNamesOneCharacter: On an organizational level; they are called both Moebius in private and the Consuls in public.
* VillainsOutShopping: Subverted; they like hanging out in a dimly lit but otherwise mundane movie theater, but it's actually the method for their SinisterSurveillance; it just looks like a movie theater due to Moebius' [[TheHedonist hedonistic]] antics and occasionally using it for [[MundaneUtility taking bets on battles]].

[[folder:Consul B]]
!!B
->''"You think you have a future? Well, you don't."''

The Consul assigned to Colony 9 and the one responsible for the protagonists from Keves being driven out of their home.
----
* BigOlEyebrows: His helmet is constructed in a way that gives him the appearance of having big intricate eyebrows, though his true face is never shown.
* DefiantToTheEnd: As he fades away, he uses his last moments to verbally spit on those that defy him.
-->'''B:''' It's futile, you know? You won't change anything. You think you have a future? Well, you don't. Only suffering and despair.
* ExtremityExtremist: When he engages the team, he only attacks with his legs, kicking waves of energy at them and shattering stones with ease. This is dropped when he becomes a Moebius.
* PerceptionFilter: Like K, he initially manipulates the members of Colony 9 into attacking Noah, Lanz and Eunie by making them perceive the party as shadow monsters. Unlike K, however, he isn't completely dependent on this strategy, and once it leads to K's death, B drops it.
* PowerNullifier: During his boss fight, he'll frequently shackle your Healers.
* RageBreakingPoint: Once Noah destroys Colony 9's Flame Clock with Zeon's help and the entire colony rises up against B, he loses it and transforms, deciding to straight up kill everyone, starting with Zeon.
-->'''Zeon:''' Prepare yourself, Consul B!
-->'''B:''' Why, you... You good for nothing imbecile! ''[goes OneWingedAngel]'' ALL DEFECTORS MUST BE ''ERRADICATED''!
[[/folder]]

[[folder:Consul C]]
!!C
->'''Voiced by:''' Creator/DaisukeKishio (Japanese), Joe Pitts (English)

The Consul who attempts to stop the party from obtaining the Origin metal, and Noah's mentor as an off-seer.
----
* AntiVillain: [[spoiler:There's nothing genuinely evil about his actions. While he ''does'' become Moebius and battle Noah and his party, it's apparent that it was merely to test their resolve, as he takes his loss in stride and encourages Noah with his dying words. Furthermore, he even went out of his way to avoid collateral damage by forcing the castle inhabitants into a slumber, which was broken upon his death.]]
* BaitAndSwitchBoss: When the party infiltrates Keves Castle for a second time, [[spoiler:the false Queen of Keves prepares to battle them once again, only to be unceremoniously cut down by Crys, who acts as the actual boss.]]
%%* TheBard: He was Noah's off-seer mentor after all.
* {{BFS}}: Wields a Heavy Guard greatsword in his boss fight.
* CurbStompBattle: [[spoiler:As the false Queen of Keves charges up fireballs to lob at the party, he dully mentions how annoying the noise is before he blasts the robot's mask off with one attack.]]
* FriendlyEnemy: He never shows true hostility towards Noah and his friends as a Consul.
* GoOutWithASmile:
** [[spoiler:After the party manages to defeat him, Noah sends him off with a melody and Crys perishes smiling as he compliments Noah's tune.]]
** This is how he also died in his previous life, as Noah's last memory of him was him smiling before he died in battle.
* TheMentor: He taught the way of an off-seer to Noah, imparting many of his own beliefs in the process.
* PosthumousCharacter: [[spoiler:C's true identity is Crys, Noah's off-seer mentor who died 4 years before the start of the game.]]
* VillainHasAPoint: C does point out that there is no guarantee [[spoiler:freeing Origin]] would actually return the worlds to the way they were before [[spoiler:they collided]].
* YourDaysAreNumbered: Implied, in Noah's last memory of him before he died and became a Moebius, his hand tattoo marks him as on his 10th term, giving him at most only months to live.

[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/xc3_d.png]]
[[caption-width-right:350:[[labelnote:Click here to see his Moebius form]]https://static.tvtropes.org/pmwiki/pub/images/maxresdefault_1_3428.jpg[[/labelnote]]]]
->'''Voiced by:''' Creator/YojiUeda (Japanese), Jonathan Slinger (English)

->''"You've got a real death wish."''

A bloodthirsty Moebius who is the first one the party encounters.
----
* AxCrazy: He ''lives'' for murder and bloodlust.
* BatSignal: A rare villainous version. He uses his eyes to project Moebius' crimson symbol on the sky to warn the other Consuls of the Ouroboros' rise, effectively declaring war on Noah and Mio's teams.
-->'''D:''' Now the whole world will be your enemy. I'll enjoy watching you.
* BladeBelowTheShoulder: He has a pair of shoulder blades in his Moebius form. He can also fire them as projectiles, which he calls "Unstoppable Spears".
* CallBack: When he appears in his Moebius form in the release date trailer, he mentions the "passage of fate". These are ArcWords for ''VideoGame/XenobladeChronicles1''.
-->'''D:''' It's a wild ride, this "passage of fate".
* {{Expy}}: Of Mumkhar/Metal Face. He's the TokenMotivationalNemesis who kicks off the game's main conflict [[spoiler:and was once a soldier who backstabbed his own men, killed the main protagonist's female childhood friend (or at least a past incarnation of her), and received the power to become his current form as a Consul by the major villainous faction of the game. While he's less of an outright {{Gonk}} than Mumkhar in his real form, he also shares his sadism, goatee, and wields near-identical WolverineClaws gauntlets. Not to mention like Mumkhar, D's demise involves falling from a very great height and blowing up in the process, though it was caused by J, aka Joran not canceling the Interlink past the time limit rather than getting stabbed.]].
* FusionDance: [[spoiler:Interlinks with J during his third and fourth boss fights, though it's unwilling on J's part in the latter.]]
* HateSink: Like Mumkhar before him, he has no redeeming qualities whatsoever and is written to be as depraved and heinous as possible. His "crowning achievement" comes when [[spoiler:he impales Queen Nia right after the party wakes her up]], though fortunately it ultimately fails.
* HeroKiller: [[spoiler:Murders Mwamba and Hackt by crushing them with his bare hands and mortally injures Guernica with an Unstoppable Spear. He also killed one of Eunie's past selves, and almost succeeded in murdering the real Queen of Agnus.]]
* HoistByHisOwnPetard: During his final fight against the party, [[spoiler:he forces J to interlink with him. This results in his death as J chooses not to break the interlink past the time limit, blowing both of them up as one last act of redemption.]]
* {{Infinite}}: In the form of Moebius he has a lemniscate on each of the two "cores" in his chest, showing his allegiance to the Consul.
* ItsPersonal: Eunie in particular has a strong fear/dislike of him as he was the one [[spoiler:who murdered one of Eunie's past-selves.]]
* MoreTeethThanTheOsmondFamily: His Moebius form has a mouth full of long, spike-like teeth.
* MrExposition: Takes the time to explain how Interlinking works to Noah and Mio after they fuse for the first time before battling them.
* ObviouslyEvil: From his enormous, hulking physique, glowing eyes, razor-sharp teeth and wine red armor that makes him look like a sort of demon with bits of flayed skin, D is pretty much designed to look as monstrous as possible.
* OneLetterName: Is referred to as "D".
* SerialKiller: [[spoiler:In his human lives as Dirk, he'd murder Agnian and Kevesi soldiers alike and keep their heads in jars inside a Ferronis.]]
* SociopathicSoldier: [[spoiler:His true identity is that of Blackblaze Dirk, a psychotic Agnian soldier who enjoyed keeping the heads of his victims as trophies. He didn't only limit himself to the opposite side, as on at least one ocassion he slaughtered the inhabitants of his own Colony.]]
* SuperSenses: His horns in [[spoiler:Interlinked]] Moebius form allow him to sense movement through air currents, making him almost impossible to sneak up on. [[spoiler:Key word being ''almost''.]]
* WolverineClaws: [[spoiler:As Dirk, they'd use clawed gauntlets while serial killing, and Taion makes a point out of noting that these were ''not'' Blades, but weapons he'd seemingly made himself.]]
[[/folder]]

[[folder:Consul E]]
!!E

The Consul of Colony Iota.
----
* InsistentTerminology: He prefers to be called "Master E".
* PetTheDog: Despite the rather [[BadBoss abusive]] reputations of the Consuls as a whole, E seems to have taken a genuine liking to Alexandria and allowed her a lot more authority than other Colony commanders, and even approved her Collectopedia Card system. After his death, one of the soldiers in Colony Iota notes that this is the ''only'' thing they respected about the late Consul.
* PrimaDonnaDirector: Similar to [[VideoGame/XenobladeChronicles2 Ahkos]], he treats his schemes like they're a play , arrogantly acts like he fashioned Alexandria into his ultimate pawn, and calls the party "side characters".
* SmugSnake: He thinks he's got Alexandria under his thumb and made her the ultimate soldier, but the truth is that Alexandria sees through his deceptions and is actually trying to gauge the Ouroboros's strength before getting them to attack Colony Iota and depose the Consul.
[[/folder]]

[[folder:Consul F]]
!!F

The Consul of Colony 0.
----
* EvilCannotComprehendGood: He's completely honest in his intentions that he and the party should work together, not understanding why they have an issue with continuing the war or treating soldiers as fodder.
* FauxAffablyEvil: Tries an honest effort to get Ouroboros to work with him - though unlike most examples of this trope, this only shows how detached he is from human life.
* HumanResources: He claims to value the lives of Colony 0 more than anything, but judging by his reaction to No. 4 dying in Segiri's arms, it's only in the same sense as valuing a powerful weapon or fuel source; he [[NoSympathy couldn't care less about them]] as people.
* KarmicDeath: He is mortally injured by Segiri, whom he molded as a mindless killer, and Sena and Lanz finish him off soon afterwards.
* KickTheDog: When Segiri requests that only she be overlocked to fight the party and spare her fellow soldiers lives, he commends her but proceeds to overclock everyone anyway.
* MinorMajorCharacter: He's the Consul second only to Y in terms of keeping the ForeverWar going due to Colony 0 serving as a fifth column that helps prolong the conflict, but he's only faced in an optional sidequest.
* NonActionGuy: He's seemingly not much of a fighter, as he prefers to let his soldiers do the fighting, and after Segiri turns on F and mortally wounds him with her Ferron, he's easily finished off by Sena and Lanz in the former's Interlink form without him even bothering to try transforming into his Moebius form.
* OptionalBoss: He can only be fought in an optional sidequest.
* SecretPolice: Colony 0 deals in information control, inciting sedition, and overall serving as the backbone keeping Aionios' ForeverWar chugging.
* WeCanRuleTogether: Tries to honestly get Ouroboros to join his side, not understanding that they find his way of doing things utterly amoral.
[[/folder]]

[[folder:Consul G]]
!!G

The Consul of Colony Gamma.
----
* ArcVillain: The main antagonist of Teach's Hero Quest.

[[/folder]]

[[folder:Consul H]]
!!H
->'''Voiced by:''' Creator/FumiHirano (Japanese), Flora Montgomery (English)

The Consul responsible for the destruction of Colony 8. She is currently in charge of Moebius's warfare against the Lost Numbers.
----
* AnIcePerson: In keeping with her Gorgon motif, she uses ice-based attacks as a boss that freeze.
* SinisterSerpent: Her helmet with its multiple snakes evokes the Greek Gorgon Medusa, and she's a villain.
[[/folder]]

[[folder:Consul I]]
!!I

The Consul of Colony Mu. She is described as frequently being away from the Colony on "special missions" and only giving vague orders to the soldiers stationed there.
----
* BecomingTheMask: While she is deceiving and manipulating Fiona and the rest of the Colony, it's implied that [[spoiler:Fiona's pure earnestness has actually gotten to her and there's a part of her that honestly does care about Fiona, as she's deeply conflicted about her actions when confronted by Fiona, with the camera pointed at her mouth at certain moments to imply her shame. When the party goes through her documents posthumously, Fiona finds a box filled with items from the special times they had together]].
* BigBadFriend: [[spoiler:She's Fiona's best friend and also the Consul responsible for all her problems.]]
* FalseFriend: [[spoiler:She spends most of her time in disguise as Irma, Fiona's best friend and the Colony's lieutenant.]]
* KilledMidSentence: [[spoiler:She dies before she can finish saying all of her last words, but it's implied to be her affirming that she and Fiona will always be friends.]]
* MasterOfIllusion: She can create illusory Volffs that nonetheless still deal very real damage. She also uses illusions to hide the Colony's Ferronis and Flame Clock, putting a fake up in its place.
* MiseryBuildsCharacter: She claims that sacrificing members of the Colony to the occasional Kevesi raids ([[spoiler:all of which are orchestrated by her]]) builds the strength of the survivors, specifically pointing out that Fiona would never have become as strong as she has without that suffering. Whether this is what she actually thinks or is her trying to justify things to herself is unclear.
* PlayingBothSides: [[spoiler:It's revealed going through her documents posthumously that she was Consul for both nations, with separate identities for each.]]
* SuicideByCop: [[spoiler:It's heavily implied that I chooses to fight Fiona and the party to the death because she feels on some level that she ''deserves'' to die for manipulating and heaping so much suffering upon Fiona, as after shooting her in the back after Fiona tries to stop Lanz from attacking her, I more or less demands that Fiona fight her and encourages her to get up while reminding Fiona that her friends are dead thanks to her. The fact that Googoo was given the key to her secret hideway with all her documents to bury brings more evidence to the interpretation that Irma had no intention of leaving the fight alive.]]
* TragicVillain: [[spoiler:While she was just as guilty of atrocities as the rest of Meobius, and knowingly [[PlayingBothSides sacrificed Kevesis and Agnians alike]] for her own ends, it's strongly implied that she genuinely grew to care for Fiona and wanted to remain friends with her. When she forces Fiona to a fight to the death despite the latter's desperation to protect her, it's implied to be driven by her guilt over having secretly hurt her friend so much.]]
* WingedHumanoid: Her Moebius form has wings on its back.
* WolfInSheepsClothing: [[spoiler:The Consul of Colony Mu uses the disguise of Fiona's best friend Irma, and is also heavily associated with the wolf-like Volffs.]]
[[/folder]]

[[folder:Consul J]]
!!J
->'''Voiced by:''' Kanon Amane (Japanese), Gerran Howell (English)

The Consul with the appearance of a child who manipulates Colony Lambda into attacking the party after K's defeat. He has some sort of connection with the Ouroboros Keves group.
----
* {{Acrofatic}}: He's noticeably rotund, but this doesn't stop him from being just as fast as any other Consul.
* BadBoss: He stabs his mudpuppet duplicates of the Agnian soldiers just to show off to his former friends along with their Agnian allies.
* BlessedWithSuck: He's one of the most powerful Consuls, but the means in which he went to obtain that power did a number on his conscience and left him permanently in the body of a child. [[spoiler:Specifically the memories of his past lives fruitlessly dying over and over again.]]
* DishingOutDirt: He can create mudpuppet duplicates of people by using their memories.
* EvilFormerFriend: [[spoiler:He's Joran, one of the Keves group's friends from their trainee days who died during the attack on Colony 14.]]
* FromNobodyToNightmare: Before he became Consul, he was [[spoiler:the weakest of Noah's childhood friends and often a target of abuse by Garval]]. Now he's one of those in charge of the perpetuating cycle of death and destruction in Aionius.
* TheHeartless: His mudpuppets have the minds of the originals but no hearts, which he claims makes them more honest with what's on their minds. In practice, this means they behave essentially however J wants them to by dialing up whatever emotion he wants to an extreme.
* HiddenDepths: Prior to him saving Lanz at the cost of his own life, he's pretty good at craving wooden dolls of Noah, Eniue, Lanz, and even himself as a Consul, [[{{Foreshadowing}} hinting at his desire for becoming stronger]].
* {{Irony}}: He mocks O and P who remained interlinked far past the time limit and blew up as a result. [[spoiler:This is precisely how he meets his own end, although it is intentional in Joran's case after the 4th fight with him and D.]]
* LettingTheAirOutOfTheBand: His mudpuppets do this upon falling apart, which he demonstrates by knifing each of them in the back one after another.
* NeverRecycleYourSchemes: He brainwashes Isurd at first similar to K, but decides against it since it would be far easier to just make a mud decoy of him. That, and K did meet his end by overrelying on that method. Overlaps with PragmaticVillainy.
* PsychoKnifeNut: He's kept a knife he once used for making puppets, now using it for more murderous purposes.
* PsychopathicManchild: Like the other Consuls, he's not the sanest of people. He's also among the youngest. [[spoiler:Justified given all the crap he went through as Joran and what he went through in his previous lives...]]
* RedemptionEqualsDeath: [[spoiler:After Noah and the others get through to him, he decides to [[TakingYouWithMe take D with him]] to the grave, ensuring the latter cannot disengage the Interlink past the time limit before diving off the cliff.]]
* SadClown: Villainous example. Behind the sadistically jovial personality and jester motif of both his Consul and Moebius forms lies a sad boy seeking a better purpose than what fate dealt him in his previous lives.
* TheManyDeathsOfYou: [[spoiler:In his prior lives before becoming a Moebius, he was killed in training, ran over by a Equites's wheel, and sacrificed himself to save Lanz during the attack on Colony 14.]]
* UsedToBeASweetKid: [[spoiler:In his prior life, Joran was a kind-hearted kid who was willing to put his life on the line for his friends. His rebirth as a Moebius destroyed his sanity with the visions of his countless deaths.]]
* VillainousHarlequin: Invoked by his helmet somewhat resembling a harlequin's tassels, akin to [[VideoGame/NightsIntoDreams NiGHTS and Reala]], combined with his psychotically childish personality. When he becomes Moebius J, his appearance is a [[MonsterClown more monstorus harlequin]] that would be perfect for a horror game, such as The House of the Dead.

[[folder:Consul K]]
!!K
->'''Voiced by:''' Creator/MitsuoIwata (Japanese), Eric Meyers (English)

->''"It's the big bad boss! Boo!"''

The Consul assigned to Colony 4. Upon arriving he hijacks the Iris of all its members and forces them to combat the Ouroboros by tricking them into thinking the heroes are LivingShadow monsters.
----
* BadBoss: While the Consuls have an entry for this as a whole, K is exceptionally unpleasant in how he constantly berates the denizens of Colony 4, particularly Ethel. Once he enters his Moebius form, he abuses the regeneration that he gains from draining the Colony's soldiers through their Flame Clock to no end.
* CripplingOverspecialization: K is excessively reliant on his Iris and on his control over Colony 4 in general, barely even attacking the party himself in favor of having the Colony's Ferronis do it while he hovers overhead. As soon as he enters a region of black fog, which disrupts his Iris, his plans crumble, and his overuse of the Ferronis draws Noah's attention to it and prompts him to try smashing its Flame Clock. After K's death, D notes just how much of a one-trick pony K was.
* DiesWideOpen: Once Lanz shuts down his helmet after he dies, K has his eyes open, with a face of pure horror.
* FaceDeathWithDespair: He dies crying and screaming like a child.
-->'''K:''' NO! '''NOOOOOO!!''' But why?! HOW COULD I HAVE FAILED?! I just... WANTED TO PLAY AROUND A LITTLE MORE! NO! I DON'T WANT TO DIIIIE!!
* LargeHam: Even by the standards of Moebius, K is something of a drama queen, making loud, bombastic statements and constantly [[MilkingTheGiantCow making grand gestures]] and poses. One of his Arts is even called "Victory Pose".
* NeatFreak: He’s very vocal about his hatred of fog.
* PerceptionFilter: His gimmick revolves around using his Iris to force Colony 4 to see the party as shadow monsters, which also allows him to see through their eyes. The other Consuls employ a similar tactic at first, but quietly drop the ruse once it gets K killed.
* SmugSuper: He smugly mocks Ouroboros when he transforms, flaunting his invincibility thanks to the Flame Clock, which gives him a powerful HealingFactor and drains the lives of Colony 4.
-->'''Taion:''' No way... He's stealing from the Clocks?
-->'''K:''' HAHAHAHAHA! My dear boy, your vaunted intuition... is SHIT!! I'm not "stealing" from them, I, as Moebius, have the right to do with the Flame Clocks as I please. You may hurt me as much as your hearts' desire, but where there is life and vitality, I'm afraid I shall ''not'' fall. Come now, ''why'' don't you give your best shot... and HAVE AT ME! Hahahahahaha, if you think you can.
* StarterVillain: The first Consul whom the party manages to destroy, and his defeat motivates the party to free the other Colonies by destroying their Flame Clocks.
* ThisCannotBe: He's utterly horrified when Noah destroys Colony 4's Flame Clock, stripping him of his invincibility and making him mortal again. He straight up screams "No! It can't be!" when he's finally defeated.
-->'''K:''' Im... IMPOSSIBLE! The Flame Clocks cannot be broken! What is this?! Who ''are'' these people?! WAH!! The Flame Clock's power, utterly lost! NO!! BUT HOW?!
* YouHaveFailedMe: Strikes Ethel down with a lightning bolt after she's beaten by Noah's party. She survives, but is knocked out cold during the entire fight with him.

[[folder:Consul L]]
!!L

A Moebius who aids X in laying waste to Colony 5.
----
* DualBoss: He's fought alongside X.
* FlatCharacter: [[LampshadeHanging Lampshaded]], X doesn't even bother introducing him on his behalf, instead just dismissing him as an underling, and his name is only revealed by the game interface during the boss fight.
* MythologyGag: He shares the same OneLetterName with L from ''VideoGame/XenobladeChroniclesX''.
* SilentAntagonist: Downplayed. While other Moebius are prone to SesquipedalianLoquaciousness, L only makes eerie grunting sounds as he slaughters the residents of Colony 5, and his only lines are at the start of the boss fight and his death quote.

[[quoteright:224:https://static.tvtropes.org/pmwiki/pub/images/tumblr_1698c47f75081f0b7f8c97d71c266afd_8b8276a6_1280.jpg]]

A mysterious masked woman who resembles Mio.
----
* BadPowersGoodPeople: [[spoiler:She has the power of possession, but is the TokenGoodTeammate of Moebius, and uses it to save Mio's life.]]
* CompositeCharacter: M is a combination of several related past ''Xeno'' characters. [[spoiler:She has numerous aspects of ''VideoGame/{{Xenogears}}''' Miang, given her ability to BodySurf into other people to make them attack each other, before ultimately settling on the body of the main heroine Mio. Her being a past life of Mio who died tragically makes her similar to the various previous incarnations of Elhaymm. And her being a victim of an abusive relationship with N due to wanting to save her against all odds also has her incorporating elements of Shion Uzuki.]]
* DeathSeeker: [[spoiler:She only wishes to die and have N realize the error of his ways, so she and Mio switch bodies so that she can be sent off in Mio's stead.]]
* DemonicPossession: She can possess people and force them to hurt their allies, as she does while fighting the party. [[spoiler:Or [[FreakyFridayFlip swap bodies completely]].]]
* DominoMask: As opposed to a full face mask like other Consuls, she wears one that covers her eyes.
* {{Foreshadowing}}: She's noted to be someone who doesn't frequently meet with the other Moebius. [[spoiler:Like she's actively avoiding interacting with them.]]
* FemalesAreMoreInnocent: [[spoiler:Like N is for Noah, she's Mio's counterpart in Moebius. However, while N was successfully corrupted by Z and is a genuine villain, M's [[GoodAllAlong villainy is an act]] and she's secretly working against Moebius.]]
* GuestStarPartyMember: [[spoiler:She briefly joins your party while in Mio's body for the boss fight against the former in ''her'' body.]]
* IdenticalStranger: She looks like Mio save for her longer hair. [[spoiler:This is because she ''is'' in a sense Mio, just an earlier one like N is to Noah who he sacrificed many Lost Numbers to bring back to life as a Moebius. More specifically, the current Mio is a being who split off from the original, and like the current Noah she was formed from the intentions she left behind when she became a Moebius, those intentions eventually taking on a new existence that could be born in Aionios (despite the usual rules of the world preventing more than one iteration of a person from existing at a time, since their essence is supposed to be entirely transferred to a new body to be reborn).]]
* IHateYouVampireDad: [[spoiler:A complicated example, as she loves the man N used to be but despises what he's become. She never asked to be made into a Moebius, her revival was part or N's deal, and she is horrified and disgusted with her LifeDrinker state. While she still loves N, she is fully aware he's become a destructive {{Yandere}} and plots against him both out of spite for what he did to her and a desperate attempt to break through his rationalizations and force him to realize how far he's fallen.]]
* LongHairIsFeminine: The main visual difference with Mio besides her Consul armor is hair that extends to her waist. [[spoiler:As a mortal, she kept it as short as the modern Mio, but started wearing it long as a Moebius...because immortality [[MundaneUtility gave her time to wash it]]. After the body-swapped Mio reveals herself and the current crisis is resolved, she actively complains to Eunie and Sena about how frustrated she's gotten dealing with it for the past month.]]
* LoveMartyr: [[spoiler:Defied. While she loves N even after centuries of being treated like a doll by him and having her wants and needs ignored, she's fully aware she can't make him let go of his abusive behaviors on her own, and she ultimately commits a HeroicSacrifice to save Mio, freeing herself from his control and finally forcing him to confront how unhappy she was.]]
* LovingAShadow: [[spoiler:Downplayed, as she is self-aware about it and the "shadow" in question is something she knows used to exist. Even after all this time, M remains deeply in love with N. Unfortunately, N has been warped into a possessive and unfettered madman. The only thing she wants is for N to go back to the kind man he used to be, but when it becomes clear she can't accomplish this on her own, she launches a ThanatosGambit in the hopes that Mio can do it, and if not at least stopping Mio from dying due to N's spitefulness.]]
* MythologyGag: [[spoiler:Her confession at the end of Chapter 5 while in Mio's body, she admits to cherishing her remaining time with "her Noah". Combined with her true desire of [[WhoWantsToLiveForever not wanting to live forever]] especially as Moebius, this calls back to Jin's previously meaningful ideals in ''VideoGame/XenobladeChronicles2TornaTheGoldenCountry'', wherein he did not wish for eternal life when confronted with the everlasting evolution cycle of Blades and Titans. How even one moment with his Driver, Lora, was enough for him]].
* SmallRoleBigImpact: [[spoiler:She doesn't appear in person much throughout the story and is KilledOffForReal, but is responsible for saving Mio's life and was also the one who gave the Cloudkeep key that'd awaken Nia to Ghondor. 1,000 years before the game, she and Crys also created the Homecoming ceremony so that those who lived their full terms would be able to die in peace, instead of just being killed by a Consul so they'd return to the cycle once more.]]
* SpannerInTheWorks: [[spoiler:The sole Moebius who wasn't converted over her own free will would end up being the one to completely undo the Consuls' carefully-planned ForeverWar.]]
* {{Synchronization}}: Taion figures out the weakness in her possession power: any wounds inflicted on the possessed will also be inflicted on her. The party suggests attacking whoever is possessed at the moment and then immediately healing them back up once the possession breaks. M, on the other hand, has no healers, so this will wear her down eventually.
* ThanatosGambit: [[spoiler:Secretly orchestrated her own death to save Mio from N's sadistic scheme and force him to realize just how far he's fallen.]]
* TokenGoodTeammate: [[spoiler:She was the only Consul turned against her will, and as such isn't obsessed with maintaining the status quo and entertaining herself at the expense of others. In fact, she's been working to break the Consuls' ViciousCycle.]]
* WalkingSpoiler: Why are most of her tropes spoilered out? Because she is [[spoiler:a previous iteration of Mio who tried to break the ViciousCycle like the current one but failed]].

[[folder:Consul N]]
!!N
[[quoteright:355:https://static.tvtropes.org/pmwiki/pub/images/xc3_n.png]]
->'''Voiced by:''' Creator/RyoheiArai (Japanese), Harry [=McEntire=] (English)

->''"It is fate. Many have tried, but none have ever managed to escape its flow."''

A mysterious masked man who resembles Noah.
----
* BadassBoast: Lets out one at the beginning of his boss fight in Chapter 6, when he finally [[UnstoppableRage loses it]].
-->'''N:''' I don't take orders from you, but... Moebius are the world itself! There can be but [[spoiler:one me]] and I AM IT! I will [[spoiler:take her back.]] My will will be mine, and all who stand in my way... ''I shall '''DESTROY!!'''''
* BlatantLies: [[spoiler:When he demonstrates the Annihilator's capabilities to Ethel, he expresses regret that he's about to test it on a scenic location favored by the Queen of Keves, and apologetically asks the Queen not to think ill of him. Given that the Queen is a literal puppet of Moebius and he knows it, he was flat-out lying to Ethel for dramatic effect. Though possibly {{subverted|trope}} given the reveal that the robot Queen was also a channel for the real one to observe goings-on in Aionios.]]
* DeathEqualsRedemption: [[spoiler:After he's defeated by Noah, he willingly allows himself to be absorbed into Noah's consciousness. Later, in the final battle against Z, N's spirit manifests and he sacrifices himself to destroy Z once and for all.]]
* DominoMask: He wears a mask that covers his eyes, as opposed to the full helmet of other Consuls.
* DullEyesOfUnhappiness: One stark difference between him and Noah once the mask comes off are his EmptyEyes. [[spoiler:It likely showcases the fact that the eternity which Z promised him is not a happy one at all and he is subconsciously aware of it]].
* EvilCannotComprehendGood: [[spoiler:Presuming that he knew the full extent of M's body-possession powers, including her ability to swap bodies, he did not ever consider the possibility that M would willingly swap bodies with Mio to go in her place at Homecoming, not only to give Ouroboros a second fighting chance and save Mio's life but to wake him up on how far he's gone from the Noah she loved. He never did see it coming under his base assumption that he and M would've been content together in eternity as Moebius]].
* {{Expy}}: A pretty blatant one of [[VideoGame/{{Xenosaga}} Kevin Winicott]], himself an Expy of [[VideoGame/{{Xenogears}} Grahf]], who is ''himself'' an Expy of [[Franchise/StarWars Anakin Skywalker/Darth Vader]]. [[spoiler:TheDragon of an EvilOverlord who wears a mask and has a [[ItsPersonalWithTheDragon personal connection]] with TheHero, performed a FaceHeelTurn to obsessively preserve the life of his loved one, destroyed everything he stood for as a hero just so that his loved one would live despite her wishes saying otherwise, has a VillainousBreakdown upon learning that he lost his loved one forever, and eventually has a HeelFaceTurn where he [[DeathEqualsRedemption redeems himself]] at [[HeroicSacrifice the cost of his life]]. To make it even more blatant, the scene in with Z turns N in the amphitheater is framed nearly-identically to the opera house scene in ''Film/RevengeOfTheSith'', where Palpatine tempts Anakin by telling him the Tragedy of Darth Plagueis the Wise.]]
* FatalFlaw: [[spoiler:Inability to process grief and dependence on a LivingEmotionalCrutch. He was once like the Noah we know, but watching his Mio die sent him over the DespairEventHorizon, eventually driving him to abandon the Lost Numbers' mission, and start a family with Mio -- which after their deaths, [[BigBad Z]] was able to capitalize on to [[DealWithTheDevil seduce him]] to the idea of an eternal life with her as Moebius, as an "endless now." By the time of the game, his inability to live without M has caused him to regress to an EntitledBastard who treats her like a doll rather than as his wife.]]
* TheHeavy: He's a subordinate to Z, but given how Z never leaves his chamber [[spoiler:and isn't really a person to begin with]], N is the one who coordinates other Consuls and Colonies to destroy the heroes for most of the game.
* HopeCrusher:
** All his NobleDemon qualities go out the window when faced with Noah, seeking only to drive the man to a DespairEventHorizon. [[spoiler:He wants to prove that if push came to shove, [[WhatYouAreInTheDark our Noah would make the same choices as he did]]. Seeing how Noah [[HeroicWillpower refuses to give up his ideals]] even after he thinks his Mio is DeaderThanDead causes quite the VillainousBreakdown coupled with the fact that M (his Mio) performed a HeroicSacrifice due to [[DeathSeeker no longer wanting to exist as a Moebius]].]]
** He appears to be trying to do the same with [[spoiler:Melia]], as it's implied he knows about [[spoiler:her using the false Keves Queen to observe the world's happenings while captured within Origin, and states that "Her Majesty" can bear witness to the deaths of Ouroboros.]]
* IaijutsuPractitioner: His main specialty. If he's sheathed his sword and starts emitting a BattleAura, beware.
* IdenticalStranger: As noted, he bares an uncanny resemblance to Noah. [[spoiler:Subverted -- he's actually an EvilTwin and HerosEvilPredecessor.]]
* ILoveYouVampireSon: [[spoiler:He made a deal with Z to revive both him and his Mio as Moebius, and he himself says that his only real driving motive is to stay with his wife for eternity. [[IHateYouVampireDad She doesn't have the same opinion of it]].]]
* {{Infinite}}: At a certain point, the lemniscate symbol glows in his right eye. His weapon also bears the same symbol.
* KickTheDog: [[spoiler:When Mio is about to be sent off during her Homecoming, N has Noah freed from his bonds and throws down his flute in front of him so that Noah can send her off personally before he's executed. Noah is so shaken by this that he simply kneels in shock and despair until M in Mio disapears.]]
* LaserGuidedKarma: [[spoiler:Upon capturing Noah and the others, he chooses to have them imprisoned until Mio's time runs out in a month, informing them that those that reach the Homecoming are [[DeaderThanDead no longer able to be reborn]] for the sole purpose of driving Noah over the DespairEventHorizon and taking a great amount of pleasure in how horribly it effects him in the following month. When the time comes and Mio disappears, he takes a moment to smother Noah's failure in his face before it's revealed out that Mio and M swapped bodies in a mutual agreement to to free Mio of her limited lifespan and M of her immortal one, meaning he's the one that lost the woman he loves, not his counterpart. Realizing this leaves him screaming in despair, just as he had wanted to happen to Noah]].
* LightIsNotGood: A Moebius in golden armor who looks like a noble samurai is just as twisted as the rest.
* LoveMakesYouEvil: [[spoiler:He's absolutely smitten with M, the Consul version of Mio, and his core motive is to live with her for eternity. Regardless of M's feelings on the matter.]]
* LovingAShadow: [[spoiler:To a much worse degree than his wife; while M is aware she is more in love with the kind man he was as a mortal, N has turned utterly delusional about what she wants, assuming she is fine with her LifeDrinker existence despite her being the only unwilling Moebius. Part of the motive for M becoming a DeathSeeker is that she's long resigned to the idea that is the only thing that will penetrate his rationalizations.]]
* MixAndMatchWeapon: Wields the same sword within a LaserBlade as Noah, but darker in color; unlike Noah however, he wields the katana as his primary weapon and only uses the "weaker" Blade as a sheath and parrying tool. [[spoiler:This is because he's a past incarnation of Noah that's fallen to villainy, but even beforehand the blade was the same color as it is now.]]
* NobleDemon: Looks down on the other Consuls and the fact they treat the ForeverWar as GladiatorGames. Subverted, however, in that this is his ''only'' moral limit; he turns absolutely sadistic when on the field.
* OffingTheOffspring: [[spoiler:Amongst those in the City he killed in order to revive M were the descendants of the son he had with her.]]
* OneLetterName: He is referred to as "N."
* OneWingedAngel: Subverted as he is one of the few Consuls who doesn't transform into a more monstrous form.
* ParryingBullets: He can use his sword to deflect bullets.
* SuspiciouslySimilarSubstitute: [[spoiler:His samurai bearing, tendency to wear a mask, and main motivation being the death of a loved one all bring to mind Jin from ''Xenoblade Chronicles 2''. N being a version of Noah also makes him similar to Grahf from ''Xenogears'', and his obsession with keeping M alive for all eternity regardless of what she wants calls to mind Kevin Winnicot from ''Xenosaga'', who tried to do the same thing with Shion.]]
* ToThePain: Chapter 5 shows [[spoiler:the lengths he's willing to go to break Noah. Starting from imprisoning Mio separated from the rest of the party and culminating in forcing him to watch the full Homecoming ceremony that would kill her DeaderThanDead. Once Noah is [[DespairEventHorizon completely broken]], he was going to finish him off by [[OffWithHisHead decapitating him]] (which would've traumatized his next lives like it did to Ashera) before]] [[spoiler:M and Mio derailed his plans by swapping bodies.]]
* TogetherInDeath: [[spoiler:At the end of the game, the spirits of N and M emerge from Noah and Mio respectively and sacrifice themselves to destroy Z while embracing each other]].
* UnholyMatrimony: [[spoiler:With his fellow [[CoDragons Co-Dragon]], M -- which isn't surprising, as they are older versions of [[OfficialCouple Noah and Mio]]. They even had a son when they were mortals. Deconstructed, however, in that M didn't actually ask to be reborn as Moebius; his feelings for her had long turned possessive and toxic, to the point she sacrifices her life for Mio's sake in order to make him realize how far he has fallen.]]
* {{Unperson}}: [[spoiler:For his crimes against the Lost Numbers, they did their best to bury him, and so by the present no one really knows who he is.]]
* VillainousBreakdown: He completely loses it after he finds out [[spoiler:M sacrificed herself to save Mio.]]
* WalkingSpoiler: It is difficult to reveal anything about this consul without divulging his identity as [[spoiler:the earlier Noah who tried to break the ViciousCycle but failed]].
* {{Yandere}}: [[spoiler:While he used to love M in a sane, genuine way, guilt from abandoning his mission to save the world and massacring the Lost Numbers to get enough embers to revive her as a Moebius has warped him and his idea of love into a crazed possessiveness that refuses to see how desperately unhappy M is.]]
* YouCantFightFate: He claims that others have tried to [[ScrewDestiny fight it]] but haven't managed to "escape its flow." [[spoiler:He's speaking from [[DespairEventHorizon bitter experience]] -- he tried to fight against Z, but watching Mio die several times over caused him to lose faith the world could ever be changed, and he eventually became Z's agent to live an eternal life with Mio.]]

[[folder:Consuls O & P]]
!!O and P
->'''O Voiced by:''' Taisuke Nishimura (Japanese), Andrew Dunn (English)
->'''P Voiced by:''' Creator/SayakaOhara (Japanese), Maria Teresa Creasey (English)

The Consuls sent to preside over Ethel and Cammuravi in Chapter 4, O is the Consul of Colony Zeta, while P is a Kevesian Consul.
----
* TheDividual: They get no screentime that isn't with each other, and while they have individual Moebius forms, they only use them in a cutscene before combining for the actual boss fight.
* {{Expy}}: Loosely, of Mikhail and Patroka from the previous game, as a duo of villains from the main evil organization with one man focused on defense and one woman focused on offense (as stated after their boss fight). They're also fought in Chapter 4 of their respective games.
* FatAndSkinny: O is a FatBastard while P is a slim woman.
* TheFriendNobodyLikes: If what D says is of any indication, the two of them weren't thought of highly by the other Moebius.
* HellIsThatNoise: They don't appear to have any more idea what the CriticalAnnoyance that comes from Interlinking for too long means than the party does, and they get increasingly frustrated as it gets louder. [[spoiler:It means they're about to become ground zero of an annihilation event.]]
* MultipleHeadCase: When O and P fuse into a single Moebius, rather than one member dominating, the resulting fusion has two heads (one for O and one for P) and uses a StanceSystem to switch between a more bestial and a more humanoid stance where O or P is in control, respectively.
* SinisterSchnoz: O's Consul helmet has a long nose that makes him look like [[Franchise/{{Persona}} Igor]] or [[WesternAnimation/DespicableMe Gru]].
[[/folder]]

[[folder:Consul Q]]
!!Q

The Consul in charge of Colony 30 and the boss of Valdi and Alexandria's Hero Quests.
----
* CoupDeGraceCutscene: After the second time he's fought Noah quickly cuts him down with the Sword of the End.
* FakingTheDead: Fakes his death after the first time the party fights him before being faced again as part of Alexandria's Hero Quest.
* PragmaticVillainy: Attempts this in his first appearance, where he assures Ouroboros that he isn't there to pick a fight, and merely wants Valdi to return with him. Though Valdi agrees, the party correctly assume that Q's intentions are far from benevolent and end up following them, culminating in a fight anyway.
* {{Technopath}}: He can take control of machines directly, and uses this ability to pilot the Levnis that Valdi was building.
[[/folder]]

[[folder:Consul R]]
!!R

->'''Voiced by:''' Creator/SayakaKinoshita (Japanese), Laurel Lefkow (English)\\

The Consul of Ashera's Colony.
----
* DuelBoss: Is fought alongside W, both in Moebius form.
* DefiantToTheEnd: Spends her last moments taunting Ashera over her past before dissipating into light.
* JerkassHasAPoint: Eunie initially agrees with her that Ashera's a "beast" who's too obsessed with fighting for her own good.
* TheAllegedExpert: Ashera says she has delusions of tactical grandeur, and ends up being correct, as R understands nothing about the reason why the soldiers of Colony 11 fight.
[[/folder]]

[[folder:Consul S ('''UNMARKED SPOILERS''')]]
!!S
->'''Voiced by:''' Creator/HarukaTerui (Japanese), Louise Stewart (English)\\

After her death at her own hands, Shania was revived by X as a Moebius and sent to attack her former comrades and family. For more information, see Shania's folder.

!!T

The Consul of Colony 15. For more information, see Triton's folder.
[[/folder]]

[[folder:Consul U]]
!!U

The seldom-seen Consul of Colony Tau.
----
* ExactWords: When called out on her plans, she remarks that she said nothing about getting rid of monsters, but of "nuisances", which is basically everyone but Juniper.
* FauxAffablyEvil: When Ouroboros and Juniper first encounter her in Colony Tau to begin the latter's Ascension Quest, she states to have been the one who dealt with the volff attack on the colony. U then convinces Ouroboros to go on a simple fetch quest to gather certain items to get rid of nuisances, only to eventually learn that said items were meant to attract monsters to Colony Tau as part of culling the colony's numbers, save for Juniper.
* {{Sadist}}: She mentions that the look of anger and horror on one's face as they're about to die is one of life's greatest pleasures.
* TermsOfEndangerment: Refers to the Ouroboros as her "Ouroberries" and Juniper as "Junebug".
[[/folder]]

[[folder:Consul V]]
!!V
->'''Voiced by:''' Yohei Tadano (Japanese), Charles Dale (English)

The Consul that appears during Taion's Hero Quest searching for the Lost Colony.
----
* DastardlyWhiplash: He has the voice, accent and mannerisms of an old-timey villain, and his Consul helmet is shaped like a top hat and has tubes resembling a handlebar mustache. On top of this, he's one of the less competent Consuls, easily falling for Taion and Riku's trap.
[[/folder]]

[[folder:Consul W]]
!!W

A Consul working with R.
----
* DuelBoss: Is fought alongside R for Ashera's second Hero Quest in Moebius form.

[[caption-width-right:350:[[labelnote:Click here to see her Moebius form]]https://static.tvtropes.org/pmwiki/pub/images/moebius_x.png[[/labelnote]]]]
->'''Voiced by:''' Creator/MarikaKouno (Japanese), Jessica Preddy (English)

The Consul of Colony 5.
----
* AmazingTechnicolorPopulation: She's got grey skin and has a purple scar.
* ArchEnemy: Eunie takes a particular dislike towards her and takes point during the party's battles with her.
* BadBoss: Most of the Consuls are pretty bad to their own subordinates but X takes a step further [[spoiler:by personally massacring Colony 5, her own Colony, with L's assistance. Only four soldiers survived.]]
* TheCorrupter: She acts as this to [[spoiler:Shania]], telling them to indulge in their worst impulses.
* DarkActionGirl: Is willing to take Moebius head-on, and is also a pretty despicable piece of work.
* DuelBoss: Her first battle has her fight alongside Moebius L.
* FaceDeathWithDespair: After being defeated in her final match with the party, she spends her last moments screaming about not wanting to die and begging Z to save her before disappearing.
* MinorMajorCharacter: To an even further extent than Y, being one of the three original Moebius, it's entirely possible to go throughout the entire game without fighting X - if Eunie's Hero Quest isn't completed, she's simply replaced with a small clump of average-levelled grunt enemies in Origin.
* MsExposition: It's her who explains the nature of the Colony ranking system, which is [[spoiler:singling out the colonies with the strongest lifeforce for Moebius to reap.]]
* OneWingedAngel: In her last battle, she fights the party in her Moebius form.
* OptionalBoss: She can only be fought if Eunie's Hero Quest is completed.
* PowerNullifier: Thanks to Z's power, her scepter has the unique ability to interfere with Ouroboros' Interlink forms and their Blades, forcing them to de-fuse and disarming them all at once. It does have a weakness: people with a strong enough bond and willpower are immune to its effects. After Mio and Noah crush her scepter while Interlinked, she's unable to use it anymore.
* RecurringBoss: She's fought as part of Eunie's Hero Quest, and again as the third to last boss of the game within Origin.
* RedRightHand: She has purple marks over her face, which seems to indicate her nature as the original Moebius since Y and Z are the only other consuls who have them.
* SigilSpam: She has a purple X-shaped mark on her hair.
* SinisterScythe: Wields a scythe as her primary weapon, and she's a villain.
* SkippableBoss: She doesn't appear in Origin unless Eunie's ascension quest has been completed, although [[spoiler:Z∞ will still transform into her likeness during the final battle]].
* VillainHasAPoint: Zigzagged. She makes an accurate point about how the Kevesi and Agnian soldiers fight and kill each other for one reason or another and don't stop for even a moment to think on if there's a different way of doing things. (Prior to the Ouroboros incident, the only one on either side to even question if the ForeverWar is the only way to live was Noah.) But this is only true because the Consuls have deliberately arranged things so that no one ever actually comes to these realizations on their own, meaning that she's only right because of her side's own selfish actions.
* VillainRespect: Seems genuinely impressed that Ouroboros could hold their own against her during Eunie's Hero quest.
* WhiteHairBlackHeart: Has white hair and is one of the most openly sadistic Moebius members.
[[/folder]]

[[folder:Consul Y]]
!!Y

->'''Voiced by:''' Creator/TetsuInada (Japanese), Colin [=McFarlane=] (English)

->''"At this late hour, I will bring my mind, spirit and flesh to bear and batter you all into oblivion!"''

The high-ranking Consul responsible for the creation of the Flame Clocks.
----
* BloodKnight: He gets very animated at the prospect of fighting the party.
-->"Come...! Come! COME!!! May the bloody sport commence!"
* FatBastard: He is one of the biggest consuls and the one likely responsible for the most suffering due to his creation of the Flame Clocks.
* FauxAffablyEvil: He may not be as openly smug as most other consuls but it does not make him any less sadistic when it comes to committing atrocities in order to satisfy his intellectual curiosity.
* ForScience: The nature of his hedonism. He conducts depraved experiments for no other reason than being curious about what the results would be.
* FloweryElizabethanEnglish: Y's sentences are peppered with a combination of Shakespearean and SesquipedalianLoquaciousness.
* GracefulLoser: Takes both of his defeats to Ouroboros in stride, and unlike X and Z, he's the only one of the original Moebius to FaceDeathWithDignity.
* MadScientist: He is the one behind the Flame Clocks which force all colonies into deathmatches. He goes as far as utilizing off-seers' melodies to control people.
* MinorMajorCharacter: He played the largest role in the ForeverWar thanks to him being the one behind the Flame Clocks, but as a character in the narrative, he's treated as nothing more than another obstacle. He doesn't even get a dedicated cutscene after he's defeated for the final time, though he does get to say some final words before his body fades away.
* PreFinalBoss: He's the last boss the party fights before Z, guarding the way to Moebius' amphitheatre.
* RedRightHand: Like X and Z, he has the purple marks over his face.
[[/folder]]

[[folder:Z]]
!!Z
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/xc3_zed.png]]
->'''Voiced by:''' Creator/AkioOhtsuka (Japanese), Creator/HarryLloyd (English)
->''"Freedom is nothing more than fiction... A deception."''

The leader of Moebius. A mysterious figure who is usually seen sitting in an old fashioned movie theater, watching events unfold and commenting on them. He gives direct orders rarely, but when he does they are treated as absolute.
----
* AnthropomorphicPersonification: [[spoiler:He's a manifestation of the people's desire for stability, and their fear of change. When confronting him, the party even acknowledge that there's an aspect of him within all of them.]]
* BigBad: He is the "true enemy" that Vandham wanted everyone to fight against.
* CompositeCharacter: He is a combination of Zanza and Malos, who were the main villains of the previous two games. Like Zanza, Z is a godlike being who secretly keeps the world in a perpetual ViciousCycle so it remains unchanged. Like Malos, he is driven by humanity's darkest desires and is more than happy to let others take the initiative as long as it suits his designs.
* ComputerVirus: [[spoiler:He's a living piece of malware formed from the two worlds' corrupted desires that infected the Origin system intended to separate them.]]
* ContrastingSequelAntagonist: To both [[VideoGame/XenobladeChronicles1 Zanza]] and [[VideoGame/XenobladeChronicles2 Amalthus]] from the previous games. While Zanza is focused on control over the future through his visions and Amalthus was lost to his traumatic past, Z is present-focused to a fault, seeking to preserve the "endless now" by any means necessary.
** Also, Z's status as [[spoiler:[[TheHeartless the embodiment of humanity's desire for stangation]]]] separates him from both the Christian-themed [[AGodAmI false god Zanza]] and the [[CorruptChurch manipulative priest Amalthus]].
* DemiurgeArchetype: Is called the "creator" of the world seen in ''Xenoblade Chroncles 3'', but anyone who has played the first two games would know that this is blatantly false, and this is made clear by the end of the game. In addition to that, he also directly benefits from the ongoing cycle of life and death by feeding off of it (like the other Moebius), similar to other Demiurge-inspired characters like [[VideoGame/FinalFantasyX Yu Yevon]], [[VideoGame/LegacyOfKain the Elder God]], and even Zanza.
* DeusEstMachina: [[spoiler:He's a combination of the Origin system's AI and the psychic residue of the human instinct to preserve a status quo.]]
* EvilIsHammy: A ''Xenoblade'' staple, most of his lines consist of [[Franchise/StarWars Emperor Palpatine]] levels of ColdHam.
* FinalBoss: He's named after the last letter in the Latin alphabet, and he's the last boss of the game.
* FlatCharacter: Z doesn't do anything except remark on fate, select and tempt Moebius, and maintain the ForeverWar. [[spoiler:Desires really aren't known for their complexity.]]
* TheHeartless: He is literally [[spoiler:humanity's desire for the status quo given shape and form, but grown beyond all sane limits; he does not care that his ForeverWar is awful for all involved, it serves as both an unchangeable form of existence and as a way to fulfill the human desire for stimulation so that nobody with the power to change things wants to]].
* HeroKiller: [[spoiler:In Noah's past life memories, at least two incarnations of Ouroboros he was involved in met their ends at Z's hands.]]
* HumanoidAbomination: He has a humanoid shape, but is in actuality [[spoiler:the embodiment of humanity's desire for things to stay the same. Once he goes into OneWingedAngel state, he reveals his true form is a mass of writhing Moebius energy that regularly mimics other people due to him drawing his existence from their desires for safety and security as well]].
* MaouTheDemonKing: As the creator and king of the vampire-like Moebius and a master of Ether manipulation in general, as well as someone who mostly remains in the background rather than be fully characterized, he fits the archetype. [[spoiler:Deconstructed, in that he isn't even really a person in his own right, either -- he's more of a personification of control. Thus, his lack of characterization is because there really isn't much to characterize, and his lack of personal initiative beyond maintaining the world is the reason for the Consuls being a NotSoOmniscientCouncilOfBickering.]]
* MonsterProgenitor: He is the first Moebius and the direct creator of the rest.
* NoPronunciationGuide: His name is pronounced "Zed",[[note]]the pronunciation of the letter Z used in the UK, Canada and Australia,[[/note]] even by characters with American accents.
* OrcusOnHisThrone: He is content to let the other Consuls run the world in his stead. [[spoiler:Justified, because as TheHeartless, he lacks actual personal goals beyond the ability to select Moebius; if the world's state is maintained, he does not have the will nor desire to actually act.]]
* RedRightHand: He has purple marks all over his face, which adds to his HumanoidAbomination look.
* VillainousBreakdown: [[spoiler:He starts to lose his composure after the party defeat his first phase, with him angrily chastising Ouroboros for persevering in their efforts despite his fears of what the future might hold. None of the heroes' pleas get through to him, culminating in him devolving into a despair-crazed being who decides that [[OmnicidalManiac oblivion is the only answer]]. It's only N and M's sacrifice that stop him from carrying out his meltdown to its logical conclusion.]]
-->'''Z∞:''' '''RAAAARGH!!'''
-->'''Taion:''' Ngh...! [[spoiler:What power! Crazy! This is the force of people's will?]]
-->'''Eunie:'''[[spoiler:You taking the mick?! It's terrifying! Not knowing how tomorrow will turn out, how you will!]]
-->'''Mio:''' [[spoiler:But still... You can't just hold it in place! If you did that,you'd never change. You can't change the world like that!]]
-->'''Noah:''' [[spoiler:That's why... I want to move on. We'll claim the future, and shape it ourselves!]]
-->'''Z∞:''' [[spoiler:And when you cannot choose? What then? In that desperate moment, who will be there to soothe you? The self is all that exists... As such, the only cure for despair is total ''oblivion!'' That is the face of the world. ''I HATE IT HATE IT HATE IT HATE IT HATE IT HATE IT! THIS ROTTEN WORLD... '''I LOATHE IT!!!''''']]
* VillainHasAPoint: The party acknowledges that it makes sense that people fear change and birthed Z, with his desire for the endless now. Ironically, this comes from their upbringing as soldiers in the world he crafted; they've lived their entire lives without even the assurance that they'll be alive when they wake up in the morning. However, Mio and Noah retort by saying that in the endless now, nobody can fix the problems with the world, which provokes his VillainousBreakdown.

[[folder:The Aegis '''(MASSIVE UNMARKED SPOILERS)''']]
!!Pyra and Mythra ''(Homura and Hikari)''
%%->'''Voiced by:'''

One of the first Blades created by the Architect and stolen from Elysium. They were friends with Poppi and Nia, the Queen of Agnus.
----
* AmbiguousSituation: What happened to them is this. It's entirely possible that they could've survived up until the present given how long-lived Blades are - Nia herself is a prominent enough example, however, Klaus mentioned that without the Conduit, they would lose their powers. The game is vague on just how far off it's been (Nia mentions Tora had a hand in Origin, meaning he was alive when construction started.) Along with the Annihilation Events seemingly being caused by them leaves MANY unanswered questions. Furthermore, as a Hero, Nia uses spectral versions of their swords, hinting that their spirits might be with her.
* BabiesEverAfter: Along with Nia, they had children with Rex as seen in the ending.
* LightIsNotGood: There is a series of events called "Annihilation Events" that happens at seemingly random locations but happens in certain regions more often then others. It takes the form of [[SphereOfDestruction Aegis-Like powers]] in colors which matches Pyra and Mythra's signature colors that leaves behind craters similar to the ones seen in ''VideoGame/XenobladeChronicles2TornaTheGoldenCountry.'' The destruction of [[WhereIWasBornAndRazed Uraya, the Titan where Mythra was first awoken by Addam Origo]] is one of them. Downplayed, however, in that Annihilation Events seem to be natural phenomenon otherwise, rather than consciously controlled by them. The Consuls have learned to provoke deliberate ones, and a SuperpowerMeltdown of an Interlink takes the form of one centered on the Interlink in question.
* LiteralSplitPersonality: As seen in the ending of ''Xenoblade Chronicles 2'' and Nia's photo in the ending, Pyra and Mythra became two separate beings after initially sharing a body.
* PersonOfMassDestruction: The destruction of Uraya, a massive titan was implied to be caused by their powers which takes the form a large SphereOfDestruction of light, but for unknown reasons.
* {{Polyamory}}: It's revealed at the very end that Rex married Pyra, Mythra, and Nia.
* PosthumousCharacter: Their role in the story is meant to give off this impression, though whether they actually passed on or not is left ambiguous.

[[folder:Superbosses '''(UNMARKED SPOILERS)''']]
!!Superbosses (Kilocorn Grandeps, Perilwing Ryuho, Dreadwyrm Nizoont, Levialord Empireo, Seraphic Ceratinia)

The five strongest Unique Monsters in Aionios. Each of them lives in a different region, and grants the party one "Aionios' Strongest" info piece when defeated. Seraphic Ceratinia can only be encountered when the other four are defeated, and notably has its own intro cutscene and battle theme.
----
* AutobotsRockOut: While the original quartet technically qualify as they use "You Will Know Our Names - Finale" as their battle theme, Seraphic Ceratinia has a unique battle theme consisting of epic symphonic rock.
* BewareTheNiceOnes: Despite its fearsome appearance and name, Levialord Empireo is comparatively docile and won't aggro the party if they go near it, unless they're right in front of it. Beware if you ''do'' attack it, though, because it's the second-strongest of all monsters in Aionios, being Lv. 110.
* TheDreaded: The five of them are feared in-universe as the strongest monsters in Aionios. Seraphic Ceratinia most of all; its cutscene is labeled in the Event Theater as "Top of the Food Chain".
* FourElementEnsemble: Each of the original quartet corresponds to one of the classical elements: Grandeps (earth), Ryuho (wind), Nizoont (fire) and Empireo (water). Ceratinia is associated with a fifth element, ice.
* GiantEyeOfDoom: Sena gets distracted by the snow that Seraphic Ceratinia creates, only to be greeted by the monster's eye staring right at her.
* GoldAndWhiteAreDivine: Seraphic Ceratinia has a white and gold color scheme and a name that suggests divinity, and is the toughest enemy in the base game.
* {{Leitmotif}}: Seraphic Ceratinia, as the hardest superboss in the base game, has its own theme music rather than reusing "You Will Know Our Names - Finale" like the others.
* MythologyGag: Dreadwyrm Nizoont guards the "Legendary Biter" item, which is implied to be Riki's weapon from the first game.
* NoSell: Dreadwyrm Nizoont's "Heat Scream" Art has it let out a MightyRoar that makes it ''completely invincible'' for a few seconds. Even during Chain Attacks.
* OneHitKO: Seraphic Ceratina's "Ultra Play Bite" Art is an instant kill on any party member that it hits.
* OurDragonsAreDifferent: Some or all of the superbosses follow this as a consistent theme.
** Dreadwyrm Nizoont is a Drague, a fire-breathing Western dragon based on the Dragons from the first ''Xenoblade Chronicles'' (albeit with a SuddenNameChange for the species), with [[ExtraEyes four eyes]].
** Levialord Empireo is a Ravoon, a sea dragon that attacks with water breath. It mostly appears Eastern, with a serpentine body.
** Seraphic Ceratinia follows the Western dragon body plan with four legs and two wings, but its wings serve as the endpoints for a fan-like appendage that it uses to perform some of its Arts. It wouldn't look out of place as a more unconventional Elder Dragon in ''VideoGame/MonsterHunter'', and also vaguely resembles Azurda from ''Xenoblade Chronicles 2''.
** Kilocorn Grandeps and Perilwing Ryuho aren't explicitly dragons, being an Ardun (bovine-''Triceratops'' hybrid) and Volgull (giant bird) respectively. However, they're vaguely related to the trope, as Grandeps is a [[DinosaursAreDragons dinosaur]] and Ryuho has some draconic features (and also has ''ryu'' in its name).
* PinataEnemy: Along with Pippito enemies, Seraphic Ceratinia is the only renewable source of Nopon Coins in the game. It can be farmed for them simply by using repeated Burst combos on it.
* {{Superboss}}: All four of them are labeled by the game as such, and have special gravestones with a red aura around them. They can be rechallenged repeatedly at higher levels each time, all the way up to Lv. 200.
* TemperCeratops: Kilocorn Grandeps resembles a ''Triceratops'', is highly aggressive, and has a much lower threshold for getting enraged than other monsters.

* ForgetfulJones: As a result of having lived for so long, he admits that his memory isn't the best. [[spoiler:His second Hero quest revolves around him trying to remember the location of an object that someone entrusted to him long ago, and he's even long forgotten how to activate his Moebius form since he hasn't used it in so long.]]
* HeelFaceTurn: [[spoiler:Completing his quest and liberating Colony 15 will result in him joining Ouroboros as an ally.]] {{Downplayed|trope}} in that he was never evil and in fact deliberately sought to have his Flame Clock destroyed, something only Noah could do.

* JackOfAllStats: [[spoiler:The Soulhacker can not only use the various Arts of Unique Monsters, but change its active role via its Role Skill, meaning that the class can fit nearly any role or situation in the game.]]
* MagikarpPower: [[spoiler:His Soulhacker class starts out with very limited options, with no master arts or talent art to speak of. However, whenever a new unique enemy is defeated while someone is deployed with it, they gain a skill from the enemy, allowing the class to be extremely customisable and powerful]].
* MechanicallyUnusualClass: [[spoiler:Soulhacker is easily the weakest class in the game when initially obtained, since each individual Art (bar its Talent Art, Final Countdown) is not available from the beginning, and Master Skills can't be equipped. However, if the Soul Hack menu is filled with a sufficient amount of Arts and Master Skills by defeating Unique Monsters, Soulhackers become exceedingly customizable powerhouses.]]

* PowerCopying: [[spoiler:The main perk of his unique Hero class, Soulhacker. As a trade-off for not having any set Master Arts and Skills of his own, Triton can acquire the unique arts and skills of Unique Monsters when he defeats them.]]

* TokenHeroicOrc: [[spoiler:He becomes a recruitable Hero after completing his quest, making him the sole Moebius to side with Ouroboros. He even requests that the party destroys his Colony's Flame Clock.]]

* AcheyScars: [[spoiler:Her neck scar appears and aches as her incarnations get older and she starts remembering how prior to the system of the Queens, Homecoming was just the Consuls personally exectuing soldiers that had reached the end of their lifespan.]]

* BloodKnight: Her EstablishingCharacterMoment has her acting rather gleeful fighting her own countrymen, and is quick to rope the Ouroboros into helping her fight her own Colony and its Consul for no other reason other than it would be fun, which unsurprisingly makes said Consul call her a "beast". Even her own men share this attitude. Unlike the other Heroes, Ashera doesn't mind fighting until her final day or even if she drops dead in combat, so long as her death has meaning. [[spoiler:It's revealed that this is because of the torment borne of her multiple deaths at the hands of the Consuls suffered by each of her incarnations prior. In her mind, a glorious death is preferable to a undignified, humiliating execution.]]

* HiddenDepths: Ashera's second Hero quest reveals that underneath her badass exterior and devil may care attitude to conflict is a deeply traumatized woman tormented by her past, or in particular [[spoiler:her past lives ending in her dying an ignoble death at the hands of the Consuls]], which is the source of her desire to die gloriously, even if it's a friend who kills her.

* PastLifeMemories: [[spoiler:Ashera has memories from past incarnations that appear to go back to around the very beginnings of the ForeverWar, as she recounts the fact that at the time the Consuls would just brutally execute soldiers that made it to ten instead of having the Queen and off-seers send them off peacefully.]]

* TheBard: Much like Noah, Mio is an off-seer, and was thus trained to play her flute to allow the souls of the departed to pass on to the beyond. She is also sometimes seen playing it at camp with Noah.

* MercurysWings: Has short wings on her head resembling those of the High Entia.

* PowerFist: Her profile picture shows her wearing two large, mechanical fists.

* TheKlutz: In comparison to Mio being a skilled soldier, Miyabi was infamous for being very clumsy, though she personally doesn't mind because she doesn't particularly like fighting.

* WhyDidItHaveToBeSnakes: Or Aspars, in this case. It's not out of fear but rather because she finds them [[{{Squick}} horrifically disgusting]] to the point she's noted to have almost vomited after fighting one.

* TheFogOfAges: When talking to Ghondor about Vandham and the events of Uraya in ''2'', she admits the events happened so long ago that she's forgotten most of the details, but the important bits of what happened remain.

* MeaningfulName: His first name, Guernica, comes from a famous anti-war painting by Pablo Picasso, reflecting how he isn't on either side of the conflict but rather working towards ending it and focuses on the "real enemy".

* OneWingedAngel: Subverted as he is one of the few consuls who don't transform into a more monstrous form.

* ScarfOfAsskicking: He's a soldier who wears a long orange scarf.

** Zeon, Teach, Gray, Isurd, Ashera, Alexandria, Fiona, Triton, Monica, Cammuravi, and Segiri are completely optional, [[spoiler:along with Nia and Melia]]. While Monica temportarily joins your party initially, unlocking her as a permanent Hero is optional.

** Zeon, Teach, Gray, Isurd, Ashera, Alexandria, Fiona, Triton, Monica, Cammuravi, and Segiri are completely optional. While Monica temportarily join your party initially, unlocking her as a permanent Hero is optional.

** Founder Reid's mentor was a composed but fierce warrior who used a bright red sword in the battle against Moebius, and continued to fight even after losing his right arm, much like Dunban.

* MsFanservice: The closest thing this game has to one, Eunie has the largest breasts out of the group, and her FormFittingWardrobe does the most to highlight her figure out of the protagonists.

* LadySwearsALot: Out of the main party, she is by far the most foul mouthed, using both in universe language like "snuff" and "spark" alongside curses from English like "bollocks" and "arsehole".

->'''Voiced by:''' Creator/YukiyoFuji (Japanese), Maya-Nika Bewley (English)\\

* ShipTease:
** With [[spoiler:Taion. Early in chapter 6 Eunie notes in a scene that gets special attention from the camera that she can be more optimistic now since she has "a reliable guy to stand with [her]." Taion is visibly flustered and asks that she outright confirm she is talking about him, Eunie teasingly noting it's a secret.]]

** Eunie and Taion are a WillTheyOrWontThey duo who receive a lot of ShipTease, but it's left ambiguous if they're romantically attracted or if it's just their own peculiar brand of {{Tsundere}} PlatonicLifePartners. In particular, a lot of Eunie's insults to Taion can be interpreted as light LovingBully teasing that he's [[ObliviousToLove too dense to pick up on]], but since she's TheGadfly it's also possible she's acting flirty on purpose purely to annoy him. In the ending [[spoiler:Eunie tells Taion he's only her fourth favorite friend, flustering him, but in characteristic Eunie fashion even ''that'' is likely a form of trolling, and again it's ambiguous whether it's her way of flirting with him one last time or she genuinely sees them as JustFriends]].

* KickTheDog: After she betrays the party and they end up in prison for a month as Mio's Homecoming approaches, she visits them at least once mainly to rub their defeat in their faces and gloat about killing herself to become a Moebius.
