History NightmareFuel / FateZero

** The anime toned it down, but not the manga. The manga shows you [[{{Gorn}} way]] [[NauseaFuel too]] [[BodyHorror much]]! ButWaitTheresMore Many of the victims that are shown are [[{{Fandisservice}} NAKED]], [[{{Squick}} UNCENSORED]], [[PunctuatedForEmphasis CHILDREN!]]

** Probably because there are no {{Eldritch Abomination}}s, serial killers, no cruel spells beings cast, or other supernatural aspects, just a paralyzed man who's lost his reason for existence (his magic), failing his family, being emotionally manipulated--and then, when it doesn't work, physically mutilated with the threat of being reduced to a limbless husk--by the one person he cares for.

** On the whole Ryunosuke and Caster are a pair of {{Nightmare Fetishist}}s made flesh, with [[spoiler: Ryunosuke's ''dying words'' being adoration at seeing his own guts spill out]].

* Episode 10 has a very SlasherMovie feel. Ryunosuke being the villain and Rin being the focus character. It has a very AdultFear theme to it. Children go missing and then Rin decides to look for them ''in another city''. She sees Ryunosuke mind-controlling kids and leading them away by the hand. Then she finds his lair. Then it's a SugarWiki/MomentOfAwesome for Rin. [[spoiler: Then Rin nearly gets jumped by one of Caster's tentacle abominations, and Kariya gets to pull an [[SugarWiki/MomentOfAwesome awesome]] BigDamnHeroes moment.]]
** The worst part, this is the anime TONING THINGS DOWN by [[AdaptationExpansion expanding things]]. The anime has Rin [[SugarWiki/MomentOfAwesome save the children]] (one of them being a friend of hers and the reason why she went after Caster in the first place) [[spoiler:before the monster almost eats her]], the light novel and manga, on the other hand, has Rin [[spoiler:being confronted by the monster, saved by Kariya and taken to her mother right as she's about to enter Caster's lair, [[DownerEnding preventing her from saving the children]] (one of them being a friend of hers and, as mentioned above, the reason why she went after Caster in the first place)]]. And the manga actually makes it worse later: At one point in the anime, Waver and Rider find Caster's lair and Waver vomits from what he sees but that [[GoryDiscretionShot we, the viewers, don't]]. In the manga, what makes him vomit, and that we unfortunately see, is [[spoiler:what Caster has done to Rin's friend, just to make sure we know that [[FailureHero she failed]].]]

* Episode 16: There's something extremely unsettling about watching [[spoiler: Lancer's complete meltdown as he dies with his honor completely crushed, raving madly at everyone present]].
** [[spoiler: Those orange eyes pouring blood... There's nothing worse (or sadder) than seeing Lancer cursing the world with that expression...]]
** [[spoiler: It's also very unsettling that Lancer's voice suddenly turned so fittingly dark and terrifying. Creator/HikaruMidorikawa may have played some terrifying villains, but none of their voices in their worst came close with how he did Lancer's last moments in how terrifying it is.]]
** [[spoiler: Kayneth begging for a MercyKill soon later. The manga still manages to make it worse. At least it's just a stab in the anime. In the manga... Saber had to ''behead'' Kayneth and we're left to see Kayneth's bodyless head rolling on the floor, and drawn in a big size too!]]
* Episode 17: [[spoiler: Kirei's betrayal and his murdering of Tokiomi. [[SlasherSmile The rather gleeful smile]] Kirei has before stabbing him is especially unnerving]].
* Episode 18: Kiritsugu witnessed a horrific event during his childhood. [[spoiler: His PrecociousCrush transforming into a Dead Apostle and then setting off a ZombieApocalypse. He has a front row seat for seeing people getting eaten. The Church's executors and the Mage's Association show up and kill the Apostles, followed by the mages deciding to torch the island to preserve the {{Masquerade}}. Finally, he finds out that all of this was caused by his own father, who couldn't care any less about it.]]
* Episode 21: Kariya's [[spoiler: strangling of Aoi is played in a disturbingly sexual way, and Kariya's wailing once he realises what he's done is haunting.]]
* Episode 22: First, it is extremely unsettling to see [[spoiler:Kirei [[IncrediblyLamePun snap]] at Irisviel because he can't stand an ArtificialHuman with genuine feelings, when he, a genuine human, can't feel real emotions...]]
** [[spoiler: Then... your emotions are jarred between incomprehension with mild horror as "Irisviel" watches herself and a cluster of Einzbern homonculi piled up on top of each other, then feeling yourself go [[TearJerker "D'aww" over Ilya making a horrible nightmare of what might await her]] since [[HiveMind Einzbern homonculi designed for the Grail War share a common consciousness]]... then further horror as this scene falls to black ashes, meaning Irisviel's mind is literally falling apart, before revealing once more the pile of clones all staring towards the screen with a broken and empty look... before [[TheCorruption Angra Mainyu]] takes over one and [[SlasherSmile thoroughly corrupts it in a twisted, horrifying smile.]] ]]
*** [[spoiler: And then, Irisviel having a full [[PaintItBlack black makeup]] EvilMakeOver and coming to a [[HeelRealization realization]] that... not only is she dead and "something" has taken over her mind, but if she is inside the Grail, then it means... [[TheEndOfTheWorldAsWeKnowIt the end is near]].]]

*** Actually if you look closely at a shot after that you'll notice [[spoiler:all of the clones are smiling!]]
* Irisviel's [[spoiler: (Angra Mainyu's)]] scream of terror as [[spoiler:Kiritsugu rejects the Grail by shooting the apparition of his own daughter in the head]]. AdultFear indeed. [[spoiler:Worse, it's unclear how much of this is the actual Iri in the Grail, and how much of it is just Angra trying to con Kiritsugu into killing the planet.]]

* Every time ''[[https://soundcloud.com/gnlu/30-the-dream-fades-before-dawn The Dream Fades Before Dawn #3]]'' begins to play. While the first half is identical to the first iteration of the song, the second half quickly descends into creepy ambience and sounds, culminating with [[OminousMusicBoxTune an off-key, twisted, and haunting version]] of the [[DarkReprise main melody of "Let the Stars Fall Down" and "Manten"]]. Considering that this plays when [[spoiler: Irisviel falls into the corrupted Grail and Kiritsugu is shown [[KillEmAll just how his wish will be granted]]]], it can be said that the song serves as the theme of [[spoiler: [[UltimateEvil Angra]] [[TheCorruption Mainyu]]]].

* [[spoiler:Kariya's death is a mixture of a nightmare and a TearJerker. Through sheer force of will, body ravaged beyond belief, he manages to walk slowly from the aftermath of Saber and Berserker's final duel-to-the-death to his home. There, he descends into Zouken's hellish basement where Sakura's innocence was robbed and says out loud that he's there to save her. He creates a HopeSpot as he imagines taking Sakura away to reunite with her family, including a healthy Aoi; reality reveals Kariya's corpse on the stairs, which then falls to the floor and is slowly devoured by Zouken's worms.]]
* One for the Einzbern Consultation Room, but based on Iri's comment before Lancer arrives [[spoiler: about how fast the Greater Grail shows up, and how dark her comments can get at times (or the JerkAss behavior of driving Lancelot insane again), it's very well possible that Angra Mainyu could be staging takeovers on Iri and directing the Servants to the Greater Grail while Iri may want to genuinely help them.]]

** Lancer's death, mentioned above, is the direct result of Kiritsugu's actions: he has [[spoiler:kidnapped Sola-Ui and signed a geas contract that meant that, as long as Kayneth had Lancer kill himself, he would not cause any harm to either of them through any action]]. Kayneth is sure that this time they'll at least survive... And then, [[spoiler:Maiya shoots them both, killing Sola-Ui on the spot and giving Kayneth a painful deadly wound]]. And when Kayneth begs a MercyKill, Kiritsugu simply points out ''he can't''. Good thing Saber was willing to grant it even without being ordered to...

** When Kayneth realized the Mage Killer was coming for him he had no fear: the hotel had been evacuated after someone (that Kayneth rightly deduced was Kiritsugu) warned about an arson, so there was no danger for TheMasquerade, and the last floor had an immense amount of traps, easily able to stop a Mage. Then Kiritsugu ''[[DungeonBypass blows up the whole hotel]] to kill two persons''. Oh, and he had Maya ready to shoot Kayneth and Sola-Ui if they left before the explosion.

** Having survived the above, Kayneth comes after him. And then, after a battle in which they figure out each other's tricks, [[https://youtu.be/ZPqVpspvepQ?t=337 Kiritsugu uses his secret weapon, the Origin Bullet]]. What Kaynet is experiencing is every single Magic Circuit in his body severing itself and then rebinding wrong, taking away his magic-including his most prized possession, the El Melloi crest-and crippling his body in atrocious pain. And he would have ''died'' in such pain, had Lancer not rescued him.

** [[spoiler: Kayneth begging for a MercyKill soon later.]]

** The scene previous to this one gives a pretty good view of a clock, which shows that the time was around 11pm. And Zouken said that put her into the wormpit "since sunrise". That is like, 18 hours staight? [[AndIMustScream It really is a miracle that Sakura is even breathing.]]

** The scene previous to this one gives a pretty good view of a clock, which shows that the time was around 11pm. And Zouken said that put her into the wormpit "since sunrise". So basically that is sickening torture for a 5 year old girl for like, 18 hours straight? [[AndIMustScream It really is a miracle that Sakura is even breathing.]]

** The scene previous to this one gives a pretty good view of a clock, which shows that the time was around 11pm. And Zouken said that he've thrown the little girl into the wormpit "since sunrise". Oh my...[[AndIMustScream It really is a miracle that Sakura is even breathing.]]

** The scene previous to this one gives a pretty good view of a clock, which shows that the time was around 11pm in the evening. And Zouken said that he've thorwn the little girl into the wormpit "since sunrise". Oh my...[[AndIMustScream It really is a miracle that Sakura is even breathing.]]

* Again from the anime, Ryunosuke Uryu and Caster's introduction is full of nightmare-inducing images. It doesn't help that both of them are immoral and insane.

** On the whole Ryunosuke and Caster are a pair of {{Nightmare Fetishist}}s made flesh, with [[spoiler: Ryunosuke's ''dying words'' being adoration of seeing his own guts spill out]].

** [[spoiler: Kayneth begging for a Mercy Kill soon later.]]

* Episode 18: Kiritsugu witnessed a horrific event during his childhood. [[spoiler: His PrecociousCrush transforming into a Dead Apostle and then setting off a ZombieApocalypse. He has a front row seat for people getting eaten. The Church's executors and the Mage's Association show up and kill the Apostles, followed by the mages deciding to torch the island to preserve the {{Masquerade}}. Finally, he finds out that all of this was caused by his own father, who couldn't care any less about it.]]

*** This actually feels like a ShoutOut to ''that scene'' in Episode 23 of ''Anime/NeonGenesisEvangelion'', only done better. Much "better", for very scary values of "better", since they actually made Irisviel completely out of the UncannyValley.

* Irisviel's [[spoiler: (Angra Mainyu's)]] scream of terror as [[spoiler: Kiritsugu rejects the Grail by shooting the apparition of his own daughter in the head]]. AdultFear indeed. [[spoiler:Worse, it's unclear how much of this is the actual Iri in the Grail, and how much of it is just Angra trying to con Kiritsugu into killing the planet.]]

* Gilgamesh's proposal to Saber was squick for a number of reasons. First, he got her attention by nailing her to the ground with a la sword through the leg. Second he tells her to marry him, and then makes it clear he doesn't care whether or not she wants to.

* Just Berserker possessing a [=JASDF=] [=F-15J=] with the pilot still inside. Also includes said destruction at the hands of Lancer.

* Episode 18: Kiritsugu witnessed a horrific event during his childhood. [[spoiler: His PrecociousCrush transforming into a Dead Apostle and then setting off a ZombieApocalypse.

** The worst part, this is the anime TONING THINGS DOWN by [[AdaptationExpansion expanding things]]. The anime has Rin [[SugarWiki/MomentOfAwesome save the children]] (one of them being a friend of hers and the reason why she went after Caster in the first place) [[spoiler:before the monster almost eats her]], the light novel and manga, on the other hand, has Rin [[spoiler:being confronted by the monster, saved by Kariya and taken to her mother right as she's about to enter Caster's lair, [[DownerEnding preventing her from saving the children]] (one of them being a friend of hers and, as mentioned above, the reason why she went after Caster in the first place)]].

** Uryu is first seen trying to summon a demon using the blood of a couple he's murdered, and informs their BoundAndGagged child that he's going to feed him to it if it works. When he manages to summon Caster, Caster unties him and [[HopeSpot lets him go]]... only for an EldritchAbomination [[YankThDogsChain to pop up behind him]] and ''devour him alive'' just offscreen, [[CruelAndUnusualDeath while he screams in agony for several seconds over the sound of his body being torn apart]].

* Episode 24: The battle between Kiritsugu and Kirei. [[spoiler: Both men are fighting to the death, using every resource available to them and the blows they land on each other is horrifying. First Kirei manages to close the distance quickly with his [[CharlesAtlasSuperpower insane speed]]] and punches Kiritsugu so hard in the chest, his heart explodes! Luckily, Kiritsugu had Saber's Noble Phantasm hidden within himself to heal himself and manages to shoot and graze Kirei's head with his Calico before shooting his Contender. Kirei tries to deflect the bullet with a karate chop but is forced to redirect the bullet by moving his arm, ''with the bullet still inside and traveling within'' resulting in a giant hole exiting his arm. Kiritsugu tries to cave Kirei's head in with the handle of the Contender while moving at three times his normal speed but Kirei blocks with his mangled arm, resulting in a sickening crunch. As Kiritsugu attempts to push his advantage and tries to kill Kirei with a knife, Kirei deflects all his blows and tries to destroy Kiritsugu's head before Kiritsugu dodges the death blow, moving ''four'' times as fast, and throws his knife into Kirei's kneecap before trying to shoot him one last time with the Contender. Not one to be outdone, Kirei throws the rest of his Black Keys in a circular formation as he charges down the middle to lock Kiritsugu in for the final death blow. The outcome of the battle is then interrupted as the Grail's black mud then breaks through the ceiling, engulfing both men...]]

* Kariya's [[spoiler:death. A mixture of the nightmare and TearJerker; through sheer force of will he manages to slowly walk from the aftermath of Saber and Berserker's final duel to the death, body ravaged beyond belief, to his home. There, he descends into Zouken's hellish basement where Sakura's innocence was robbed and says out loud that he's there to save her. What looks like a HopeSpot as Kariya takes Sakura away to reunite with her family, which includes a healthy Aoi, is then slowly revealed with Kariya's corpse on the stairs, which then falls to the floor as it is slowly devoured by Zouken's worms...]]

* Episode 10 has a very SlasherMovie feel. Ryunosuke being the villain and Rin being the focus character. It has a very AdultFear theme to it [[SavedByCanon despite the fact that Rin is a pivotal character around 10 years later]]. Children go missing and then Rin decides to look for them ''in another city''. She sees Ryunosuke mind-controlling kids and leading them away by the hand. Then she finds his lair. Then it's a SugarWiki/MomentOfAwesome for Rin. [[spoiler: Then Rin nearly gets jumped by one of Caster's tentacle abominations, and Kariya gets to pull an [[SugarWiki/MomentOfAwesome awesome]] BigDamnHeroes moment.]]
