History YMMV / XenobladeChronicles2

** Pyra's [[GagBoobs unrealistically large and gravity-defying bosom]] tend to be a major distraction during some cutscenes.

** Labelling Poppi as a "sex robot", Tora as a LoveableSexManiac, or anything similar simply because of the questionable in-universe design choices is another easy flame war starter. While there are a couple of jokes of that nature in the Japanese script, he never gets to the point of actually doing anything with them. It's also shown in the same chapter they're introduced that Tora had genuine reasons for building Poppi in the first place, [[spoiler:which are further explored in Chapter 4, along with why she even has such design choices]].

* FanworkOnlyFans: One of the reasons Pyra and Mythra are BestKnownForTheFanservice is their vast amounts of RuleThirtyFour from artists who have admitted to never playing the game or were commissioned to do so by people who didn't, but were still attracted to Pyra and Mythra's designs. While this is mitigated by their NewbieBoom thanks to being included in ''Smash'' to make them more easily accessible, it still resulted in an explosion of fan art created or enjoyed by people that also have no interest in ''Smash'' but were attracted to how hot they were. This leads to skewed perceptions of the two girls in terms of their personalities and relationship with each other and Rex. Even ''Rex'' isn't safe from this as his proximity to the Aegis sisters makes him reduced to a tool for Pyra and Mythra to dominate, not unlike how the FanworkOnlyFans of of ''VideoGame/NierAutomata'', ''VideoGame/KidIcarus'' and ''Manga/ChainsawMan'' believe [=9S=], Pit and Denji are nothing but submissive toys to [=2B=], Palutena and Makima[[note]]the latter ''does'' lean into the notion quite a bit, but it ends up far more complicated than that[[/note]] thanks to the large amount of femdom art they have, not realizing they go through a lot of CharacterDevelopment.

* {{Narm}}: Some of the cutscenes in the English version, and to a lesser extent the Japanese version are a HongKongDub. While this may result in a more natural performance, there are many instances where a dramatic line is delivered before the character's body actually reacts, which just looks plain silly especially when said line is PunctuatedForEmphasis, such as Zeke's EstablishingCharacterMoment in the English dub. The Japanese dub at least has [[AnimationBump characters' lip movements animated to match the dialogue]] in more important scenes, whereas the English dub has no such privileges.

** Malos is also this, for his over-the-top LargeHam performance and sexy factor.

* CommonKnowledge: Pyra and Mythra are only a few inches taller than Rex as best seen when they are introduced to him, but the fact that they frequently spend time around shorter characters like Rex, Nia and Tora causes the fan base to assume they're towering over most people they meet when in reality, [[https://www.reddit.com/r/Xenoblade_Chronicles/comments/aq2czt/official_character_height_chart_from_xenoblade_2/ the artbook has noted]] the Aegis sisters are just average for two humanoid girls. Thus, fan art of the Rex x Aegis girl [[https://www.reddit.com/r/Xenoblade_Chronicles/comments/q5rjpt/ara_ara_rexkun/ ship has become memetically infamous]] for exaggerating how tall Pyra and Mythra really are, [[https://twitter.com/magicalgirlnoir/status/1423287965439053828 a situation not unsimilar]] to how fans of ''VideoGame/NierAutomata'' years earlier assume 2B completely towers over 9S, especially given that it emphasizes the "stoic, but dominant tall sword girl x submissive shorter guy" dynamic that both the Rex/Pyra/Mythra and 9S/2B ship share.

** Nia is initially skeptical of Pyra's motives and cautions Rex not to trust her just because she seems nice. [[spoiler: In ''VideoGame/XenobladeChronicles3FutureRedeemed'', Na'el (who incidentally is implied to be Rex and Nia's descendant) comes across Ontos' core crystal and more or less becomes Alpha's Driver, but their relationship is nowhere near as balanced as Rex and Pyra's was, and ultimately Alpha ends up overpowering her and using her as a host for their plans. In addition to being an inverse of Malos, Alpha is basically what Pyra could have been if Nia was right.]]

** Malosblade/Metsublade, for the very popular ForWantOfANail FandomSpecificPlot where [[spoiler:Rex takes up Malos as his Aegis of choice while Amalthus wields Mythra]].

** RoleSwapAU stories for the two Aegises are common, with Malos becoming Rex's Blade while Mythra is the BigBad. It helps that canon provides an easy explanation for the difference: Since Amalthus obtained both Aegis cores and only awakened one on a whim, he could've simply [[ForWantOfANail grabbed the other one instead]]. Despite his more heroic role, Malos tends to retain his abrasive personality, sometimes driving a wedge between him and Rex. The two learning to work together often makes up much of the early conflict. Since Pyra/Mythra are on the villains' side, Nia often gets promoted to Rex's primary {{Love Interest|s}} -- if he's not being [[SlashFic paired with Malos]], that is.

** While the inconsistent English voice direction does have its obvious lapses, using said moments to invalidate the entire dub and/or the voice actors' competence is also an easy way to rile fans up. Rex gets hit with this the worst. This is because despite these, the game has hours of dialogue, and the entire cast have fine moments of their own and sound more adjusted to their roles as the game goes on. The same even goes for Rex.

* Jossed: In one part of the game, the group fights an Infernal Guldo and it drops an ID card with a woman's face on it. Players assumed that this ID card belonged to [[spoiler:Galea, the scientist who became Meyneth from the first game. However an interview with Takahashi in the "Aionios Moment" artbook confirmed that the ID card wasn't Galea's.]]

* LGBTFanbase: The game has a ''lot'' of fans in the LGBTQIA+ community due to the varied, attractive and colorful character designs. Most notably, Nia and Jin have backstories that can easily be put through a RainbowLens, being particularly relatable to transgender fans. Other characters also get notable attention from queer fans, notably Pyra/Mythra (being the "gateway character" to the game for many fans thanks to ''VideoGame/SuperSmashBrosUltimate'' as well as very beautiful women with {{stripperiffic}} costumes and whose [[Creator/SkyeBennett voice actress]] is confirmed queer), Mòrag (being a non-sexualized and intimidating yet beautiful {{Bifauxnen}} military leader who appeals to ButchLesbian fans), Zeke (being a WalkingShirtlessScene LargeHam who appeals to BaraGenre fans), Pandoria (a Blade whose English voice actor is non-binary, with a design and personality highly reminiscent of that community), Roc (canonically considered neither male nor female by the game mechanics), Sheba (a ''canonical'' LipstickLesbian who dreams of an "entourage" of beautiful women), and Corvin (an archetypical {{twink}}).

* JustHereForGodzilla: A lot of ''VideoGame/{{Xenosaga}}'' perked up when they saw KOS-MOS had showed up as an [[InfinityPlusOneSword extremely powerful rare Blade]].

** It's also not uncommon for fans to interpret Mórag as a trans woman, since she has an androgynous {{Bifauxnen}} appearance and a very deep voice courtesy of Creator/MitsukiSaiga that could be mistaken for a man's. In addition she's shown as being somewhat sensitive over other characters mistaking her for male, despite her masculine appearance and mannerisms. The existence of Sena in ''VideoGame/XenobladeChronicles3'', who is vaguely implied to be related to Brighid and possibly even her daughter, caused an increase in the number of fans who believe Mórag may be a trans woman, and that if Sena is Brighid's daughter, she may have helped her conceive.

** Mikhail, [[spoiler:specifically the recruitable Blade version of him on NewGamePlus. Despite being a major character in ''Torna ~ The Golden Country'' as a child and retaining his memories because he was originally human, he doesn't have any special interactions with Mythra, Brighid or Aegaeon, three Blades who he traveled and spent time with for the enire game. Mythra most of all, considering how Mikhail and Milton were good friends who were often seen together and how Mythra was close to both of them, and how Milton's death was the very ''reason'' why she went on a RoaringRampageOfRevenge and sealed herself away.]]

* DiscreditedMeme: For years, Rex's [[LovesYouAndEverybody response]] to Nia's LoveConfession was touted as the poster child of the StockShonenHero characters and how dense they were when romance was involved. [[spoiler: And then the ending of ''Xenoblade Chronicles 3'' revealed that he [[MarryThemAll actually followed through on that statement]], marrying Nia ''alongside'' Pyra and Mythra. Unsurprisingly, nobody used "I love you and all you guys" as a sticking point against Rex since]].
