History NightmareFuel / XenobladeChronicles2

* Amalthus' true nature. For most of the game, he comes off as a fair-minded, if slightly cold and ruthless leader. But at the game's climax, its revealed that he was so broken by watching mankind succumb to its worst and darkest impulses of years that he's become a bitter, deranged OmnicidalManiac, convinced that condemning Alrest to oblivion would not just be a mercy, but also the will of the Architect.
** The scene where his true colors are revealed. After dispatching a group of suddenly hostile Indolines, Amalthus appears and, in a tone angrier than he's ever been before, ''demands'' that Rex use the Aegis to open the way to Elysium. When Rex questions this, Amalthus ''loses it'', his eyes glowing red as he madly declares to entering Elysium and receiving the Architect's blessing is ''his'' right, not Rex's.

** Even after it's revealed afterwards that everyone except Pyra and Mythra were manifestations of Rex's worst fears, there's still some added FridgeHorror. The others, including their blades, had very similar visions, which are not seen.

* In a flashback, Amalthus and Zeke discuss about some bandits who Zeke thinks that could steal Pandoria, and explains how due to Pandoria looking very much human, that she could be selled as a core with pictures of how they look awakened. Essentially, he's describing how they are putting blades as possible ''[[SexSlave sex slaves]]''. Due to this very dark fact, Amalthus mentions how horrible humanity can be, saying that "as soon as people are denied of something, they try to take it by force".

** This ends up temporarily turning Pyra into an empty shell by the time Rex comes to save her. However, Earlier on in a scene with Patroka and Akhos, it's implied that [[KickTheDog Malos didn't even need to erase Pyra's memories to restore his Aegis powers,]] which only adds to how Malos is depicted much more monstrously in this scene.

!! Torna: The Golden Country
* Mythra in her UnstoppableRage is absolutely terrifying, not only can Addam not control her because of their less-than-ideal bond, but Addam is still getting electrocuted after touching the third sword even when it's no longer in his hand. It's very similar to Dunban's pain of not being able to use the Monado. Then there's Mythra's screams, which shows she is in absolute agony. The only thing she wants until she snaps out of her RoaringRampageOfRevenge is to make Malos suffer.
** As if beating Malos wasn't enough dread for players who already know what's going to happen, one notable detail is that after Mythra enters said rage and awakens the third sword, [[EmptyEyes her eyes lose their glint]], and she also has a [[DullEyesOfUnhappiness dead-looking expression]], making Mythra appear almost soulless. This is the same facial expression she had in the brief flashback at the start of chapter 4 in the main game. This is also the [[FiveSecondForeshadowing first detail]] that shows something has snapped inside her, and the only time it changes before the end of the fight is when she completely loses it inside her siren to fire at a downed Malos.
* Torna: The Golden Country ends with a fight against Gort, who has been turned into one of the first Blade Eaters, a titan-like abomination that's a more deliberate but intelligent version of a Guldo, courtesy of Indol. His human face embedded in the beast's mouth sports a horrifying SlasherSmile). It gets worse when it's shown Indol made several of them to attack the remnants of Torna.
-->'''Gort:''' I'll use your blood as a balm for my wounds. How about it? Sound fair? Yeah?! *Pops a [[WolverineClaws Wolverine Claw]] out of his prosthetic arm* I'll start with you, you Tornan Blade! I'm paying you back for cutting my arms off, you dog! I'll have me arms back... And I think I deserve... some interest, too... I'll take your ears and nose as well!
** Even his last words are creepy, as he says the following as he weakly tries to slash Team Lora once last time. Despite not a lot of time passing, what starts off as a petty DefiantToTheEnd moment quickly sounds way less like himself and more like the sadistic monster he was turned into at the last second.
-->'''Gort:''' But I...! I still wanted...I still wanted to play...!
-->'''Lora:''' Shameless, till the very end...

Despite being LighterAndSofter than [[{{VideoGame/Xenogears}} previous]] [[{{VideoGame/Xenosaga}} Xeno]] [[{{VideoGame/Xenoblade}} series]] [[VideoGame/XenobladeChroniclesX games]], ''Xenoblade Chronicles 2'' is still at it when it comes to including content that makes the [[UsefulNotes/EntertainmentSoftwareRatingBoard ESRB's T rating]] dubious at best.

* [[AndIMustScream Klaus' fate]]. Half of his body is trapped in [[VideoGame/{{Xenoblade}} another universe]], while he remains in his home dimension. Physically, only half of his body is visible, with dimensional rift covering the other half. Not only that, but his other half doesn't just refer to his body, but also toward his [[LiteralSplitPersonality evil split personality]], whom he sees and hears through, and knows every thought of. Oh, and Klaus himself is also unable to die as long as his other half is still alive.
