* Several of ''{{Narutaru}}'''s most horrific scenes fall under this. The most infamous examples include the test tube incident, the victim of said attack getting her bloody revenge on the main perpetrator by [[HoistByHisOwnPetard siccing her own torture methods onto her]] via her newly-acquired [[{{Mon}} Shadow Dragon]], and the utterly brutal rape and murder of [[spoiler:Norio]] in the manga.
* ''{{Bokurano}}'' by MohiroKitoh has a guy getting half his hand sliced off, in detail. In the manga, there's also the scene where [[spoiler:Chizu]] slits [[spoiler:Kako]]'s throat.
* ''Manga/{{Naruto}}'':
** Orochimaru's fight with four-tailed Naruto where he sheds his body like a snake skin, and makes a copy of himself, by gagging one out of his mouth.
** Kimimaro's Kekkai Genkai: even more so in the manga, because his fingers split in half so he can fling the bones like bullets, pulling his spine out of his back and uses it as a sword, and other things.
** Shino and the other members of his clan are human insect hives. Made worse when the FridgeHorror hits you that, with the expendable manner the insects are in use and their short lifespan, they have to be ''continuously mating inside his body'' (this is actually made explicit in the anime and he even has a technique where he ''makes them mate faster'').
* ''PeacemakerKurogane'' has Suzu carrying around his masters head in the last episode which eventually decays into a skull. As well as a good number of the battles towards the end.
* ''{{Berserk}}'': A Nausea '''Gas Station'''. The horrors of the Eclipse from Volume 13, for example.
* ''{{Hellsing}}'':
** In the TV series, there's [[spoiler:Luke Valentine's demise, wherein he is eaten alive by Alucard's hellhound]]. While the worst of it is never shown, it's the ''sound effects'' that turn the stomach.
** In the second OVA, [[spoiler:the audience sees him get devoured with body parts and limbs flying everywhere (which are then eaten) and gallons of blood decorating the walls.]]
** [[spoiler:Rip Van Winkle's death]] in the fourth OVA.
** [[spoiler:Child!Seras helplessly watching her mother's corpse being raped]] in the seventh OVA.
* ''VisualNovel/HigurashiNoNakuKoroNi''.
** Shion ripping off her fingernails with a torture machine as punishment.
** Rena constantly scratching at herself and maggots oozing out of her cuts.
** [[spoiler:Keiichi]] clawing out his own throat.
** The scuffle between Rena and Rina.
** Rika [[spoiler:scratching her throat out after stabbing herself in the neck many times]] in the manga, as well as [[spoiler:her death in Minagoroshi-hen]].
* ''VisualNovel/UminekoNoNakuKoroNi''.
** Second arc. First tea party. Leaves a person [[NarmCharm not knowing whether to laugh, cry, or hurl]]. Maybe all three at once.
** [[CruelAndUnusualDeath The first twilight.]]
* ''PerfectBlue'':
** The scenes where Mima is being photographed naked.
** The corpses that have their eyes gouged out.
** The photographer being stabbed in his eye, ''his crotch'' and then repeatedly stabbed over and over by the supposed "pizza deliverer".
** Me-Mania's physical appearance [[spoiler:and his attempted rape of Mima.]]
** [[spoiler:The final battle between Rumi and Mima.]]
* TokyoTribe: "Goosh Goosh". It's so bad there are reaction videos of it. It features [[spoiler:a morbidly obese man raping a young male prostitute to death]], and all the while he keeps saying [[{{Narm}} GOOSH GOOSH! GOOSH GOOSH!]]
* Several bits in ''Anime/NeonGenesisEvangelion'' like the Bardiel fight, which ends with the angel's viscera splattered over a town and several mountains. [[spoiler:Kaworu's death]], where his body is crushed and his head blown off from the pressure. And the part where Eva Unit-1 defeats Zeruel and then '''eats it'''.
** There's also everything in ''TheEndOfEvangelion''. [[spoiler: Especially the way Asuka checks out, getting ripped to shreds and devoured by the Mass Produced Evas]].
* ''New GetterRobo'' has an astounding number of shots of fat pilot Benkei's hairy/warty ass and testicles, for a 13 episode series.
* ''Manga/ElfenLied'':
** The beginning of the first episode, Lucy's various other murders throughout the series, [[AbusiveParents what happened to Mayu]], and Bandou's fights. The man gets an arm cut off, another one broken, and his eyes forced through their sockets by Lucy.
** The cruel kids from Lucy's childhood who kicked the puppy she had been caring for against a wall and beat it to death with a vase as they forced Lucy to watch in horror. And [[BewareTheNiceOnes then]], [[UnstoppableRage she]] [[YourHeadASplode snapped]].
* ''VisualNovel/SchoolDays'': The ending of the anime. [[spoiler:Sekai stabbing Makoto causing Makoto to make gurgling noises, his eyes to bulge out of his head, and ends with him lying in his blood. Later, Kotonoha is revealed to have cut off Makoto's head and carries it around with her in a duffle bag. Then she stabs Sekai, which releases a torrent of blood, and cuts into her stomach so she can look for the baby inside. Finding none, she stands up, covered in Sekai's blood and we are treated to a inside looking out shot of Sekai's stomach. The final scene features Kotonoha lying on her families boat, and holding Makoto's head close to herself with an expression of absolute bliss on her face. It's much ''much'' worse on DVD where the blood is red and everything]].
* The {{Fingore}} in ''Anime/{{Monster}}''. The fat, ugly hooker talking about Roberto's BiggusDickus.
* ''The Holes''
* The scene in the first episode of ''HaibaneRenmei'' where Rakka's wings develop to full size in a matter of seconds. Includes all the blood and gory stuff you'd expect when two new appendages suddenly grow out of someone's back.
* Hiromu Arakawa's masterpiece ''Manga/FullmetalAlchemist'' has quite some notorious examples, [[spoiler:including the thing that the Elric brothers created when attempting to resurrect their mother]]. Her earlier work ''StrayDog'' has some minor examples restricted to a few pages, but those present are profoundly disturbing; that is, [[spoiler:unless human remains and vivisection related imagery is your thing]].
* ''FrankenFran'' is entirely built on this.
* [[CreepyTwins Hänsel and Gretel]] from ''Manga/BlackLagoon''. They slaughter everyone they can because they can, sacrifice children to get out afterward, play some really sick games with the survivors of their assaults and are smiling the whole time. Them being probably [[BrotherSisterIncest incestuous]] is likely their ''least'' disturbing attribute.
* That EldritchAbomination in ''Manga/{{Akira}}''.
* Author of ''Manga/BlackButler'' Yana Toboso certainly seems to enjoy the gory side of life, what with [[spoiler:the orphan murder rituals, vomit covered Ciel clinging to Sebastian]] and, in the second series of the anime, Alois Trancy [[spoiler:[[EyeScream trying to gouge his maid's eye out]]]] at the breakfast table for kicks. Plus [[spoiler:the sword they keep in Hannah's esophagus]]
* There's an element of Nausea Fuel in ''anything'' by JunjiIto, but the short story ''Glyceride'', the part in ''Manga/{{Uzumaki}}'' where [[spoiler:they eat the snail-people]], and the whole kidney arc of ''{{Tomie}}'' in particular. Also, the additional ''Tomie'' story in ''Museum of Terror'' where [[spoiler:her ex-lover continually beats her constantly regenerating body to a pulp, and then disposes of said pulp by ''turning it into sake'']].
* ''SpiritedAway'':
** particularly when Sen has to bathe the muck monster, but worse is when No-Face is purging himself.
** The early scene where the parents transform into pigs is pretty repulsive.
* The scene in the manga of ''{{Tactics}}'' in which we see Kantarou as a child, taking a shit, and we get a good view of the turd coming out. Whoever thought it was a good idea to show that must be one sick person.
* ''DeadLeaves''
** For starters, the scene where they stick the tubes up the prisoners' asses and suck out all the fecal matter.
** And the scene where a guy with a drill for a penis shoves it up another guy's ass.
** And the guy who has balls for a head, with sperm oozing out of it.
* ''Anime/PuellaMagiMadokaMagica''.
** [[spoiler: Mami]] being eaten alive by [[spoiler: Charlotte.]]. In the anime you don't see it, [[HellIsThatNoise but you hear it]]. In the manga, you see it ''all''.
** In the prequel ''Oriko Magica'', [[spoiler: ''[[KillTheCutie Kazuko-sensei]]'']] is the one who gets chomped on. It's just as ugly.
* The animated adaption of ''LightNovel/FateZero'' gives us Zouken's...welcome to [[spoiler: Sakura]] via insect-rape. She's a girl of like 5, and you get to see the aftermath in glorious high definition. [[spoiler: He also implies that he raped her on the first day she was here - which, those who played Heaven's Feel in VisualNovel/FateStayNight know to be true.]] Not only does it make you want to throw up, it does absolute wonders towards your hatred of Zouken.
* You thought volume 13 of ''{{Berserk}}'' was bad enough, then you haven't read ''WolfGuyWolfenCrest'', which brings up the nausea fuel to [[UpToEleven level eleven]] right around chapters 74-76.... and ''[[RapeAsDrama it]]'' lasts for several more chapters.
* ''Anime/PantyAndStockingWithGarterbelt''. Monsters in the beginning of the series always were some sort of personified NauseaFuel. Shit monster, sperm ghosts who died during masturbation, bulimia monster who had boobs for eyes, vomit monster that causes others to retch all over Tokyo, etc.
