History NightmareFuel / HonkaiImpact3rd

** Herrscher of the Void herself is this. It's Kiana taken over by her SuperpoweredEvilSide in the form of Sirin, the ''original'' Herrscher of the Void whom Kiana (actually K423, [[CloningBlues a clone]] of the ''original'' Kiana) was basically [[RaisedAsAHost created to be]] [[DemonicPossession the reincarnation body for.]] She's cold, cruel, vicious and vindictive, and she reaffirms her domination of Kiana's body by using it to bring destruction and suffering. She's ''especially'' focused on [[MindRape driving poor Kiana mad with hatred and despair by torturing her loved ones and messing with Kiana's mind]] using her [[MasterOfIllusion powers of illusion]] and [[BreakingSpeech judicious use of hateful diatribe.]] Keep in mind that she ''[[NearVillainVictory nearly succeeded]]'' in [[TheEndOfTheWorldAsWeKnowIt destroying the world once already]], and even after averting ''that'' the world still turned into even ''more'' of a CrapsackWorld than it was [[PersonOfMassDestruction because of the damage she still did!]] The ''first'' time she was stopped, [[HeroKiller she killed Kiana's mother Cecilia and scores of Valkyries]] (including Cecilia's entire team of S-Rank companions!) and nearly killed Siegfried too, and the ''second'' time necessitated [[MentorOccupationalHazard Himeko's]] HeroicSacrifice to stop the rampage and then [[DefectorFromDecadence Fu Hua's]] to make it just ''barely'' stick. Even with Fu Hua's consciousness working full time to help Kiana keep her ego under control, Sirin is ''still'' there, [[SealedEvilInACan very much awake, aware and ready anytime]] to [[GrandTheftMe steal back control of the body]] should Kiana's emotional state plummet or she overuse her powers; Kiana is a ticking time-bomb who could go off at any moment, releasing the walking disaster that is Sirin upon the world once more.

** Fu Hua attacks Herrscher Bronya in a way that would make [[LightNovel/FateZero Berserker proud]]: by hijacking, riding, and crashing an anti-aircraft missile. Bronya shields herself from the blast in the ocean, only for Fu Hua to break through anyway [[SlasherSmile with the most psychotic smile we've ever seen on her face]], forcing [[EmpathicWeapon Project Bunny 19C]] to [[HeroicSacrifice sacrifice itself to save its owner.]]

* The moment when Fu Hua [[ExtremeMeleeRevenge cold-bloodedly murdering Otto]] at the beginning of Chapter 20. ''In the first-person view''. After Fu Hua freed herself from Otto's containment pod since the Battle of Schicksal (Chapter 8), three different {{Compelling Voice}}s are trying to convince her that Otto is a wretched viper responsible for every mess that happened in Chapter 8 and 9. Those voices claim themselves as Fu Hua's Id, Ego, and Superego, respectively, which implies being Fu Hua's LiteralSplitPersonality. With the help of her Id and Superego, Fu Hua managed to regain consciousness, killing Otto with extreme prejudice, and ransacking the entire Schicksal HQ. Then Durandal found Otto's corpse, presumably horrified of what happened after that. While this moment is undeniably cathartic for those who hate Otto since Chapter 8 and 9, seeing a stern but well-meaning class monitor turned into a ruthless individual is nothing short of horrifying and heartwrenching. Then again, Otto is a person who loves playing contingencies, even from the grave; as Theresa said to Bronya during a briefing in the next cutscene, he is not an easy person to bring to justice.

** Tying directly into the last part of the previous paragraph: The page image is a failure screen from the first level of ch. 10 in the game's Story mode, where Kiana has had the Herrscher of the Void subdued but is still struggling to control it. If you use your Herrscher energy too much in the level, regardless of how far you get, you immediately fail, with the image showing that the Herrscher has succeeded in permanently taking control of Kiana. It's probably the one image in the game that's played for straight horror and is very effective.

* The trailer for the upcoming animation, "Reawakening", serving as the prelude to Chapter 20. The good news: Fu Hua has returned! The bad news: [[RedAndBlackAndEvilAllOver she's]] gone [[AxCrazy completely insane.]]

--->'''Kiana''': You are...
--->'''Fu Hua''': Can't recognize me anymore, Kiana? [[WhamLine I will reverse all of creation.]]

* The Honkai in general can be considered nightmare fuel. They're an unstoppable force with the sole purpose of destroying humanity. They can turn normal people into mindless grunts, create sleeper agents out of the Herrschers, they evolve with civilization to keep it in check, and are seemingly endless in numbers. The worst part? THEY'VE ALREADY SUCCEEDED IN DESTROYING HUMANITY ONCE, and they're more than ready to do it again.

* Thank goodness the "bubble universes" in the Sea of Quanta are basically simulations, because otherwise [[AlternateUniverse World 3]] in Chapter 11 would be ''significantly more horrifying'' than it already is. When Welt turns on the Valkyries and starts a mass slaughter, things go south ''rapidly''. When Mei attempts to take charge of the situation and tries to come up with a new plan, she's just suddenly ''obliterated'', driving poor Kiana right into the DespairEventHorizon. While Bronya is trying to escape with Seele and Kiana, both of them disappear in quick succession, implying Welt's mechs killed them both as well (though Seele shows up alive later, Kiana has no such luck). By the time Bronya defeats Welt, it's implied that almost nobody out of both Schicksal and Anti-Entropy are left alive, and there are barely any surviving Valkyries.

** Fu Hua defeats Argent Knight [[TheAce Durandal]] by turning dozens of the former's feathers into spears and [[ImpaledWithExtremePrejudice destroying the latter's King phantom.]]

* In the ''Moon Shadow'' manhua, we get a close-up of the nasty experiments performed in Schicksal's research labs; an A-rank Valkyrie gets the Gem of Serenity (the core of the Herrscher of Death) implanted into her body in order to test its compatibility. The experiment suddenly turns into a failure as the Valkyrie's body [[CruelAndUnusualDeath slowly and painfully disintegrates]] due to being unable to withstand the core's power. Her grandfather, one of Schicksal's scientists, [[ForcedToWatch can't do anything but watch her slowly die]], while Otto coldly states the results of the experiment and nonchalantly tells the staff to clean up the mess.

The World of ''Honkai Impact 3rd'' might look like a cutesy, eroge game on the surface, but the storyline is not for the faint of heart. If you have the stomach for it, here are disturbing facts from this easy to get mobile game.

* Chapter 8, Act 2's ending cutscene teeters between TearJerker and nightmare fuel as a pure MookHorrorShow for Anti-Entropy's robot army. Think about it, your best friend is possessed, nearly strangled you to death, you can't get through to her, and now she's summoning an endless army of Honkai beasts that not even an army of robots can stop. The real kicker is Herrscher of the Void catching an entire artillery barrage and sending it right back at Anti-Entropy's forces, wiping them out in one go while Mei looks on in horror. The most unnerving part is the very last shot of Herrscher of the Void (together with Benares), standing over the destruction... then she glares at the viewer out of the corner of her eye as the cutscene ends.

* Thank goodness the "bubble universes" in the Sea of Quanta are basically simulations, because otherwise [[AlternateUniverse World 3]] in Chapter 11 would be ''significantly more horrifying'' than it already is.

* The fate of Jixuanyuan, a hero who sealed herself along with the [[EldritchAbomination Chiyou]] only to end up inside [[EldritchLocation one hell of a]] WombLevel, [[WhoWantsToLiveForever alive]], [[AndIMustScream awake]], [[FateWorseThanDeath aware]] and [[GoneMadFromTheIsolation alone]]. By the time the hero trio get to meet her, [[FallenHero her soul has completely eroded from the torment]], forcing them to [[MercyKill put her out of her misery]], which she [[GoOutWithASmile thanks them for as she dies]].
