History YMMV / XenobladeChronicles3

** Agnus Castle is where the high emotional stakes of late Chapter 5 and early Chapter 6 take place, but once those are out of the way, it reveals itself as a very underwhelming self-contained area. Agnus Castle acts as a HubLevel of sorts for many of the game's sidequest chains from that point forward, but doesn't have much else going for it, as the explorable area is very small[[note]]only consisting of the Ascension Grounds and a small jail[[/note]] despite the imposing size of the massive floating palace. Comparing it to Keves Castle can make one wonder whether the developers simply ran out of time to make it as fleshed-out as its Kevesi counterpart.

* DisappointingLastLevel: The final dungeon, [[spoiler:Origin]], is generally viewed as one of the weaker parts of the game due to a lack of environmental variety compared to previous final dungeons and an overabundance of aggressive flying enemies, along with a relative lack of cohesive story progress until the ending, [[spoiler:which is somewhat of a ShaggyDogStory given that both worlds are reset rather than progressing beyond Ouroboros' progress in liberating the colonies from their Flame Clocks and rescuing the Queens]].
* DracoInLeatherPants: Some fans have been willing to overlook TheMole's actions even if [[spoiler:Shania willingly throwed in her lot with Moebius and painted a target on the City that could've killed thousands by seeing her as a victim of circumstance, citing how Ghondor was unknowingly worsening Shania's self-esteem with her BrutalHonesty, her mother showed NoSympathy towards Shania's aspirations that didn't involve the City's protection while [[{{Hypocrite}} doing little to help the City herself]], and Sena was acting as a MoralityChain who could've kept Shania on the straight and narrow. It also doesn't help that ThereAreNoTherapists, as is standard with many [=JRPGs=], so Shania's defenders are willing to view the {{Jerkass}} comments that she throws as more so desperate cries of anger, and favourably look at her characterization in Sena's Ascencion Quest]].

** Taion is declared by many Japanese fans to be the most moe character in the game due to the wide gulf between his [[TheStoic outwardly stoic behavior]] and his true personality as someone who is deeply caring and nurturing (a popular example being his [[spoiler:excited reaction to [[FriendToAllChildren seeing a newborn]]]]), which is considered very "[[UsefulNotes/AnimeFanspeak gap moe]]". Likewise, other traits like his [[LethalChef terrible cooking]], frequent {{tsundere}} moments, tendency to be [[ButtMonkey teased by other characters]], easily-flustered, {{Adorkable}} nature, and his TrademarkFavoriteFood being the same as Pyra's[[note]]although the reference was lost in the English version for DubInducedPlotHole reasons; Pyra's favorite Pouch item, "Jenerossi Tea", is known as "Sirius Tea" in Japanese[[/note]] are seen as evocative of past franchise heroines like Pyra and Mythra, who were also known for having heavy moe appeal, resulting in the Japanese fanbase in-joke that he's the true heroine of ''3'' over Mio.

** Eunie and Taion demonstrate a lot of what seems to be BelligerentSexualTension and have a couple of scenes of more overt ShipTease, but while it's heavily implied that they are mutually attracted to each other, it's never outright confirmed. Thus, there is still some room to interpret their relationship as a particularly {{Tsundere}} variant of PlatonicLifePartners whose CannotSpitItOut issues stem from being too proud to admit that they're VitriolicBestBuds rather than being nervous about their growing feelings for one another. A lot of Eunie's insults to Taion can be interpreted as light RomanticRibbing that he's [[ObliviousToLove too dense to pick up on]], but at the same time since she's TheGadfly, it's also possible she's acting flirty on purpose purely to enact the heterosexual equivalent of GayBravado as good-natured trolling. For a specific moment that sparks a lot of debate, during the ending when Eunie [[spoiler:says Taion is her fourth best friend, was she being literal and just saw Taion as a friend, or was she flirting with him in a teasing manner? It's even possible that it was a roundabout way of saying Taion is the most important person to her, since Eunie likes to collect '''Four'''tune Clovers. Another possibility is that she's telling him he's chronologically the fourth person to achieve best friend rank with her]].

** Even though it was made clear through prerelease footage and story beats that [[spoiler:he wasn't going to [[WeHardlyKnewYe last long]]]], Mwamba garnered a lot of fans who loved him for being a Machina, being a genuinely NiceGuy, and in an ironic sense, having a silly name. [[spoiler:Thankfully, he appears as a new incarnation near the end of the game and becomes a prominent NPC in City sidequests.]] Some fans consider him to be this game's equivalent of [[VideoGame/XenobladeChronicles2 Captain Padraig]].

*** Nia's child [[spoiler:is all but said to be Mio (or at least, her original incarnation), based on interactions that they have during Nia's Hero Quest and after Nia is reawakened that heavily imply the relationship between the two. Not only that, but Mio's Core Crystal is nearly identical to the one that Nia has, and she shares physical similarities with Nia, such as her silver hair and Gormotti ears. Likewise, while the above picture heavily implies that Rex is Mio's father, Nia being a common recipient of TransAudienceInterpretation has resulted in some fans holding out that it was actually ''Pyra or Mythra'' with whom Nia conceived Mio. This latter theory would get a boost in attention after the ''Aionios Moments'' artbook showed concept artwork that gave Mio Pneuma's Core Crystal at one point in development after her Gormotti traits (and thus her implied descent from Nia) had already been finalized]].

*** Mythra's child is even more debated, as [[spoiler:the blonde hair color isn't one that any of the Agnian Heroes in the game possess. The most common guess early on was Isurd due to the fact that Mythra's child has forehead markings resembling Isurd's TronLines and that he uses light-based disc launchers; as Glimmer has darker hair than Pyra, the same could hold true for Mythra and her son, as some children in real life develop darker hair colors later in life. Another popular candidate is Alexandria, since her Core Crystal is a distinctive emerald color (supposedly unique to the Aegises) with a shape that resembles Mythra's earrings, and she is a CriticalHitClass like Mythra as well as an Attacker to round out the role trio with Mio and Glimmer. Some have even speculated that ''D'', [[CompleteMonster of all people]], may be her son because he's the only prominent blonde Agnian character in the game, and has a similar face structure to adult Rex's (with all the trauma that would entail). His name can also be read in Japanese as "gifted ruler", or "the people's ruler", similar to "king" (Rex). His Core Crystal and real Blade are also unseen. The fact his eyes are a shade of dark-amber rather than golden are a counterpoint, but it could be a result of lingering genetics. However as time went on this theory has largely been derided by the fanbase at large and is mainly just considered a joke or annoyance. After the Version 2.1.0 update, fans then started to jokingly point to Miibomii (a Nopon) as Mythra's child due to their prominent visual similarities, sometimes also theorizing that Tora is the father. The most out-there theory with some degree of sincere supporters is that Crys, despite being Kevesi, is Mythra's son who somehow managed to cross sides. ''Aionios Moments'' would show a design of Mio with a Pneuma-shaped Core Crystal which led to a new theory that Mio ''was'' Mythra's daughter at some point in development, which gave rise to the idea that Mythra's unnamed child is Mio's twin sibling from Nia rather than Rex]].

** Likewise, [[spoiler:Hero Melia]]'s postgame outfit incorporates elements of a character she had HoYay with, this time [[spoiler:Fiora. More specifically, she wears a purple version of the red diamond pendant Fiora wears around her neck, which some fans have interpreted as CoordinatedClothes and a sign of that their friendship in ''1'' may have evolved into something more]]. [[spoiler:Melia's]] Ascension Quest also has her talking about a dearly cherished friend who meant a lot to her and was a great inspiration in her youth, [[spoiler:who in context is probably supposed to be Shulk. However her flashback montage of fond memories of the events of ''1'' and ''Future Connected'' closes off on a quizzical lingering shot of ''Fiora'' instead.]] The base game, ''Future Redeemed'', and the artbook's explanations for the true nature of Lucky Seven taken together [[spoiler:namely that Melia created Lucky Seven as a product of her heart resonating with Origin, that it contains the soul of someone incredibly dear to Melia, and lastly that it was forged specifically as a vessel to store Fiora's soul so that she could change the world, point towards Melia viewing Fiora as her most important someone]].

** There's a fan theory that Mio's class was originally intended to be a Healer class while Taion was going to be an evasion-based Defender, but that they switched roles relatively late in development to make Mio less of a carbon copy of Nia and her Twin Rings. People who subscribe to this theory point to the fact that Mio's inherited classes and her best class ranks are all consistently Healers, that Taion's Tactician arts are references to the dodge tanks Brighid and Aegaeon, and that Taion's Mondo are particularly prone to GameplayAndStorySegregation in cutscenes relative to the other default weapons, being able to accomplish [[BarrierWarrior defensive]] [[MasterOfIllusion tasks]] that his class can't actually utilize in-game but which would be very handy abilities for a character intended to be a dodge tank, as signs of WhatCouldHaveBeen.

*** [[spoiler:Pyra and Mythra's children are much less obvious, with people debating if they even are preexisting characters encountered in ''Xenoblade Chronicles 3''.

*** Noah's mentor Crys was extremely commonly believed to be Shulk and Fiora's son since the trailer first dropped due to his design resembling a mix of the two, as well as his kind heart and mentorship being considered reminiscent of Shulk's endgame values, which he symbolically passes onto Noah. Seemingly [[spoiler:{{Jossed}} by ''Future Redeemed'', which reveals Shulk and Fiora did have a son together, but that his name was Nikol and that he was a GenerationXerox. Nevertheless many still hold onto this theory, believing Nikol was not an only child and that Crys and Nikol were brothers. Furthermore, those who also theorize that Noah was part of that family believe that the relationship between Crys and Noah was a result of unconscious BigBrotherMentor instinct coming through]]. Others theorize that Crys is the son of Shulk and Alvis, given that Crys resembles Shulk but not Fiora and has Alvis's eyes, as well as a personality and role in the story which heavily mirror Alvis's.

* AssPull: The official artbook includes [[WordOfGod an interview with series creator Tetsuya Takahashi]], in which he [[MindScrewdriver answers fan questions about the plot.]] While most of these details were either already heavily implied or make sense, fans reacted with shock and confusion at the reveal that Lucky Seven contains [[spoiler: Fiora]]. Not only was this never hinted anywhere in the game (at most, there was Riku's statement that there were important people inside it, i.e. that [[spoiler: it had the souls of all Shulk's companions]]), but the other ''developers'' in the interview was just as baffled as the fans were.

*** After the base game's release, the ending's [[GainaxEnding ambiguous nature]] produced three distinct camps. One camp [[AudienceAlienatingEnding hates it]], believing it rendered the whole game and everyone's efforts to liberate the colonies and help the Heroes grow and bond completely pointless since [[labelnote:('''SPOILERS''')]]Aionios is erased from existence in order to restore the original two worlds, with the cast unlikely to remember any of their experiences and potentially never seeing each other again[[/labelnote]], on top of it being incredibly vague about what happened to the casts of the past two games and leaving a lot of plot questions unanswered or open-ended. The other two camps loved it, finding it an incredibly [[TearJerker emotional send-off]] to the game's characters that, at the very least, [[SoftReboot works in a vacuum]]. Of the ending's fans, one camp believe the ending to be more on the sweet side, accusing the haters of having misunderstood the game's plot and themes, and pointing to [[spoiler:Noah hearing Mio's flute and vanishing as proof that at least the child-aged inhabitants of the two worlds were able to reunite and that liberating the colonies was still important and what would allow the Heroes to follow suit]], while the other part believe the ending to be deeply bittersweet, that the open-ended ambiguity and lack of answers is deliberate and part of the charm as an example of the game's message about taking risks and not letting the fear of the unknown be an obstacle, and [[spoiler:the cast never seeing each other again after being reborn]] perfectly fits the game's message about letting go of the past and moving on. All three camps of fans accuse each other of misunderstanding the game's themes and messages, although the latter defenders tend to get along better with the haters.

Of the ending's fans, one camp believe the ending to be more on the sweet side, accusing the haters of having misunderstood the game's plot and themes, and pointing to [[spoiler:Noah hearing Mio's flute and vanishing as proof that at least the child-aged inhabitants of the two worlds were able to reunite and that liberating the colonies was still important and what would allow the Heroes to follow suit]], while the other part believe the ending to be deeply bittersweet, that the open-ended ambiguity and lack of answers is deliberate and part of the charm as an example of the game's message about taking risks and not letting the fear of the unknown be an obstacle, and [[spoiler:the cast never seeing each other again after being reborn]] perfectly fits the game's message about letting go of the past and moving on. All three camps of fans accuse each other of misunderstanding the game's themes and messages, although the latter defenders tend to get along better with the haters.

** Consul U is considered one of the worst Consuls in the game for her irritating SmugSnake personality, as demonstrated during her role in Juniper's widely-disliked Ascension Quest. In said quest, she comes off as very ObviouslyEvil and a BitchInSheepsClothing, who nonetheless is ''not'' treated as a joke by Ouroboros and manages to fool them with a [[IdiotBall rather obvious evil plot]]. She's especially considered obnoxious due to the fact that she's prone to EvilGloating, with her monologues going for minutes on end due to her [[PurpleProse intricate vocabulary]], and she usually tends to do two or three incredibly long monologues before Ouroboros is even allowed to fight a boss.

*** Juniper pulls in many queer fans due to being an explicitly nonbinary character with a [[CuteKitten cute]] [[{{Nekomimi}} Catperson]] design and a likeable personality who is admired by their peers and whose gender identity is respected and treated as perfectly normal by the setting.

** Isurd is often referred to as [[WebVideo/Jerma985]] due to his prominent physical resemblance to the streamer.

** The lingering identity of Consul A, who does not appear in the main game but is implied by Consul I's notes to exist, has been subjected to all manner of theories as to who they might possibly be. While the most basic theory is that Consul A is just another random masked figure like the majority of the in-game Consuls, some theorize that Consul A might actually be an existing character from the series' past, such as Alvis or the Nopon Archsage, or even from the non-Blade games, like Abel or Albedo. Others theorize that Consul A doesn't actually exist at all and Consul I was lying or incorrect, or even that A stands for [[AnthropomorphicPersonification all of Aionios itself]]. The [[spoiler:Alvis]] theories gained a lot of steam with the preview for the DLC campaign, which shows the character very prominently in it, although {{Jossed}} with the actual DLC which indicates [[spoiler:Alvis and his two components Alpha and A are all opposed to the Consuls]].

** Defenders as a whole fare pretty badly in this game, to the point that many dispense with them altogether. The biggest issue is that, with the exception of Lone Exile (which has a LightningBruiser moveset) or Zephyr (which attacks fast enough to spam its one Aggro-generating Art frequently), most of them are terrible at maintaining aggro, or have few-to-no options to even generate it in the first place, despite it being ''their very job''. That the [[GameBreaker game-busting]] Protector's Pride skill (obtained from Guardian Commander) and the Fraternal Badge equip (obtained from Puzzled Raquinu in the Rae-bel Tableland) can speed up Arts cooldowns to mere fractions of their normal rate if non-Defenders are targeted, even further disincentivizes the use of Defender classes at all, and both can be obtained before the game's midpoint. The class system provides a wealth of Master Arts with invincibility windows, making it possible to configure various Attacker classes into ersatz Dodge Tanks, particularly when synergized with the above, rendering Face Tank classes almost useless and the better Dodge Tank classes merely good as opposed to great.

** Rex had this based on his appearance in the ending photo alone, with many people complimenting his KidHeroAllGrownUp design and claiming that his polycule relationship with ''three'' beautiful wives added to his "gigachad" prowess. Come ''Future Redeemed'' and this version of Rex appears in the flesh, living up (or even ''exceeding'') everyone's expectations.
