This section is in alphabetical order by series. Before you add examples here, check the index above and make sure the series doesn't already have its own page.No Hentai examples, please, as per wiki rules.
Apocalypse Zero. The big lady in episode one who kidnaps a young couple, rips the boyfriend's face off when kissing him, eats him alive, and later on throws up the decayed body of the boy... who isn't even dead yet! The girlfriend, on the other hand, gets caught up in the giant lady's hand and squeezed to the point where her ENTRAILS ERUPT OUT OF HER MOUTH as if she was a living tube of toothpaste... also she was pregnant.
Much of the events of Ayashi no Ceres. Some examples: Stiletto/dagger that can form from out of Tooya's inner wrist. Plus that monster underground (only included in the manga) that had resulted from an innocent girl mutating when she tried to put on the hagoromo and fused with it? Not pretty at all.
While the original Battle Royale novel was filled with this, the manga's even worse. Let's put it this way: If Kazuo Kiriyama is on panel, let's hope you weren't planning on sleeping anytime soon.
Hirono's face as she drowns in the manga adaptation. She was strangled half to death and then pushed down a well, and as she dies she experiences a hallucination where she's saved. As it ends, the next page fills with her swollen face, bug-eyes bloodshot, and an utterly ghastly Joker-grin.
The ninth Black JackOVA in its entirety. Especially once you reach the halfway point, wherein you get to view the most horrific Fan Disservice you will ever see. And don't get us started on the blood-spewing tumor shaped like a mutated human face.
If the Blue kill a human, but aren't hungry, they store the body in a cocoon... after compacting it to be as small as possible, complete with loud sounds of bones breaking and joints being dislocated.
The slaughter of the refugees in episode 6. Instead of going with a Battle Discretion Shot, you get to see Choppers crushing civilians underfoot or slicing their limbs away, as well as the Maneater slashing at a mother and her child, or crushing a man in its jaws.
The Clincher: the power-sucking Blue from episode 11, specifically what it does to the Axe Crazy soldier who decides to attack it. The thing knocks him to the ground, leaps on top of him, and its tentacles coil around his head. You can hear him scream, but you have no idea what it's doing to him. Later, it reappears, and the tentacles have grown into the soldier's head.
Canaan has everything Liang-Qi does after Alphard abandons her, and at least a bit of what she does before that. Never before has a Psycho Lesbian taken the very concept of a Freak Out so far magnificently culminating in her death by Ua Virus, accidentally self inflicted. This shot◊ in particular. If you can't make it out through all the blood, she's smiling.
Cowboy Bebop episode "Pierrot le Fou". A balloon-esque, practically invincible manchild with a permanent Slasher Smile who spends the episode floating around, laughing, trying to kill the protagonist. His defeat is even better. He gets trampled to death by a parade of creepy, animatronic amusement park mascots the size of small buildings, all while screaming like a child in the grips of a nightmare from which there is no escaping.
In Divergence Eve, there are many moments like this as the series progresses however, the most gruesome moment happens towards the end of the series, when Luxandra can't get her Rampant Armor to move, and then resulting in Luxandra getting eaten alive by a Ghoul, kicking, screaming for her life.
.hack//SIGN: The song "Aura". It's about a girl who is kept in a vegetative state by a corrupt and jealous mother-figure.
If you are near to the dark I will tell you 'bout the sun You are here, no escape From my visions of the world You will cry all alone But it does not mean a thing to me
Dream Hunter Rem: This being an anime about dreams and nightmares, expect lots of this.
Durarara!!, the whole 'Saika' the slasher tsundere storyline. Ranging from the chat posts "I", "must", "cut", "mother", "mother", "mothermothermothermothermother..." to the lovely horror that is Saika's theme song called Kokoro wo Shibaru Ai no Kotoba
Ergo Proxy always was a little on the creepy side, but the episode "Ophelia" topped all of the other episodes.
There is a manga out there called Fetus Collection. It's Exactly What It Says on the Tin. Google at your own peril. If you decide to fall for the Schmuck Bait, here's a synopsis of the manga: "A suicidal girl enters a little group of sick woman that made abortion a grotesque art. With usual Kago sick humor and nonsense."
Escaflowne has some in the second episode. When the cloaked Zaibach guymelefs attack, they aim their extending claw weapons at a handful of guards who don't know what they're up against. A frame later, and they're all legs with metal claws where their torsos used to be.
Kyo's true form and how it smells like rotting meat.
Full Metal Panic!: Gauron actually wanted to kill Sousuke when he was eleven and canonically wanted to rape his dead body. It also gets even creepier when one realizes that their countless encounters are most likely not entirely coincidence and that Gauron is heavily implied to be stalking him, actively choosing missions / jobs that would put him in a position to see his "precious boy."
Tampering with the janitor's fish will lead to very bad things.
Geno Cyber, just the whole thing. From children being disintegrated by gunfire in a ridiculously gory fashion, people being torn to shreds (organs and all), to giant worms erupting from people's bodies, this series is pretty screwed up. Especially the hospital scene in Episode 1. There is more gore in this 5 minute sequence than the whole of Elfen Lied.
The final volume of Getter Robo Go, starting with the revelation that the Humongous Mecha Shin Getter Robo (or rather, its power source) is sentient. Particularly what happens to Gai. He's so scared of the machine that his mind breaks and he becomes trapped in nightmarish hallucinations. When he tries to blow the machine up with a missile launcher, cables extend out the machine and eat him alive until his grinning face is fused into the side of the robot. That scene, and again where Shin Getter absorbs its pilots, the villains, the villains' fortress/mecha, and a good chunk of the North Pole before flying to Mars, imply that being absorbed brings enlightenment and takes people into some kind of heaven though.
The Grandizer manga. Probably not surprising since it has the same creator as Devilman, but it's supposed to be a robot manga for kids! Particularly when the villains kidnap all the children from Planet Freed, suspend them by ropes from their UF Os and then drop them from 3000 feet in the air. In graphic detail.
How about their mother after the air raid? Bloody bandages all over her body. Then it cuts to her face; the eyes and mouth are just pools of blood, and the rest of the face is covered in bloody bandages. Then, when she dies, the flies and maggots somehow make the whole thing even worse.
Hell, you could put the entire movie in this section. Which would you rather watch: a fun action epic, or a nightmarish and depressing drama about non-heroes?
The Haruhi Suzumiya chapter, Endless Eight, the group is going Groundhog's Day on the last two weeks of summer vacation. Sound's familiar? Rika suffered through just over 100 years. Nagato says they've been through those same two weeks 15,498 times, which comes out to 594 years and a little over 5 months. And she remembered every second of it. Small wonder she looks bored.
Asakura in the fourth episode alone is already scary. But, for the love of god, listen the way she says "You think it's a... joke? Huh. You don't wanna die? You don't want me to kill you?" It's really creepy, and you just realize that behind that happy-go-lucky facade, there is nothing.
In the movie, just when Kyon is starting to realize that something is off about the world, he happens to turn towards the door just as someone walks in. There before him stands Ryoko Asakura, back from hell with a casual smile on her face. Kyon has never been so abjectly terrified before.
That's not even the worst part. Just as Kyon is about to shoot Yuki, Ryoko appears from behind, successfully backstabbing Kyon! And then she goes on about telling Yuki that she's there for her while touching her face in a rather interesting way. And she was spinnin' around like a happy child with a bloody knife in hand. Yuki's expression explains all.
One episode of Hell Girl: The Two Prisoners involves a guy who dumped his pregnant girlfriend, who then decides to send him to Hell. His torture? Being slowly drowned in amniotic fluid while a giant fetus floats next to him. As if this isn't enough, while on the ferry to Hell his stomach is very swollen and something appears to burst out of him Alien style.
Cerbius, the Silver Tribe's Nodos, which looks like a combination of a skeletal human and a giant insect. A little disturbing on its own, but when it goes into Berserk Mode, it turns into a horrible, shrieking thing combining insect, demon and the monster from Alien. Cerbius's screams will haunt your nightmares. They don't sound like anything an Earthly creature would ever produce.
Frenzied Nodos in general are this trope: frenzied Bellcross is perhaps worst, considering he's The Hero. Up to that point, Bellcross had been an unstoppable force of good. Then he takes too much damage, Turns Red, and enters Berserk Mode. Suddenly, his power is amplified to hundreds of times his usualnote his usual power level is enough to shatter moons and survive planetary implosions and he becomes an even more unstoppable force of pure rage. He begins destroying everything: hostile fleets, friendly fleets, Deimos, even himself, as his body rips itself apart under the strain of its own power. What's truly frightening about it is that there is nothing anyone can do to stop him: a Nodos is already practically invincible, a frenzied Nodos is even moreso. And the Frenzied state is contagious; any Nodos that attempt to restrain a frenzied one are likely to suffer it themselves.
If the front page cover of the manga Hideout of some corpse-like figure ripping through the fourth wall to get you doesn't frighten you, then this closer pic of the same Nightmare Face peeking out of the darkness will.
Alluka."Onii-chan, Die For Me!" Let alone how she can warp reality to either give you exactly what you want...or how she can do the same thing to gruesomely kill you.
Several scenes at the beginning of Iczer-One, but particularly the one where Nagisa Kano's schoolgirl friends suddenly have strange mechanical faces with an eyeball in the middle.
The manga Ikigami: The Ultimate Limit (lit. "Death Papers") is both this and Paranoia Fuel. In order to help the civilian population learn the value of life, and thus become productive, valuable members of society, children are inoculated with a special vaccine. This vaccine protects them from every disease known to Man, true, but one vaccine in thousands contains a special device that will cause a heart attack between the victimcitizen's 18th and 24th years. It doesn't matter how you've lived your life up to that point —if you've wasted it, if you're happy and successful, if you're a horrible criminal or a saint loved by all. You will die. There is nothing you can do to prevent it, no one to plead to, no one to save you. Your fate was sealed when you were a child, and the only mercy you get is a 24-hour notice immediately preceding the activation of the device (and heaven help you if you're not home to receive it.) Maybe you'll receive your ikigami in the morning as you go to school. Maybe it will be in the middle of the night after a hard day at work. Or maybe during your wedding?
The Inuyasha manga had a lot of horrifying moments. For example, the entire Noh Mask arc had some serious Body Horror going on. The scene later in the manga in which two children clutch their parents' severed heads is pretty bad, too.
Kannazuki no Miko has a very famous scene that can be taken as being horrifying. While most of the show really comprises of MoeSchoolgirl Lesbians and mechas, there's one scene in Episode 8 that either horrifies viewers or turns them on. It's the scene where Chikane actually rapes Himeko. As the series went on, you found out her reasoning, but still.
The series has many of them, since it involves explicit rape as this, but the one scene that stands out from the rest is when Bonnard kidnaps and rapes an underage Gilbert. The scene is very squicky considering that Gilbert was about nine years old.
Everything Auguste does is this in spades, especially when he rapes a young Gilbert. The worst part about it? Auguste is his father who was posing as his uncle.
Kemonozume by Masaaki Yuasa loves this trope, from the Gorn and the horroristic opening of episode 6 (involving cannibalism) to anything that has to do with Ooba Kyuutarou.
This example from The Kurosagi Corpse Delivery Service needs some explanation: There's a type of snail parasite that takes up residence in the poor creature's eyestalks, enlarging them to thrice their natural size. It pulses and throbs in order to attract attention from birds,so that it may be eaten and continue its life cycle inside the bird. One story in volume 4 shows what happens when it crosses over into humans - Eye Scream, Body Horror and Squick in one well-drawn,nauseating two-page spread.
Koharu from Koharu No Hibi. Behind that sweet cute exterior she's really a Yandere for Akira. And boy is it creepy.
The end of the first episode of Le Chevalier D Eon. The plot of the series is about to pick up as Lia possesses D'Eon for the first time. Cut to the Queen in her chambers talking to a little girl who has a high pitched voice. Turn to face the mirror and she only has a skull for a face! After this, we get a close-up as she says, "Won't this be fun, Marie?" It becomes less creepy later, but it just comes out of nowhere.
Left Hand of God, Right Hand of the Devil, by Kazuo Umezu. In one particularly gruesome story, a mentally unstable father lures three hikers into a lone cabin in the middle of the woods, beheads one, and forces the other two to keep eating, no matter how full they get. In the finale of the picture book, he draws a cake, topped with the heads of the two hikers, writing that "The girls who loved cakes become a cake themselves, and they lived very happily." Happily ever after, indeed...
Life can be quite unsettling. It features graphic depictions of someone cutting themselves, but that's just the beginning. This scene of a sliced wrist is just Nausea Fuel but the warped "demonic" look of Manami some times.. It'sreallycreepy at times.
Captain Continental for one. Also, his rape of Jonathan, all those grunting noises and the screaming...
The ending where Leonard turns into a monster and Jonathan has to kill him.
Although he completely deserved it there's also Captain Continental's Groin Attack at the hands of Leonard which also possibly ends up killing him.
Lucky Star has Keroro and Tamama's cameo as tadpoles in the OAV. The two initially start out relatively normal, for them anyway, and then suddenly there's a close up as their faces transform into the equivalent of unholy monsters, both clawing and biting at the screen.
The Viktor Vajra drone. 30 meters high, capaple of vapourising cruisers, with huge claws and jaws... and no brain to speak of.
In just the first episode, Alto's partner is seized by a Vajra mecha and reduced to chunky salsa in its bare hands. We don't see the body (but sometimes that's even worse]], but we do see a lot of blood coming through its fingers.
The part in Oh Great!'s Majin Devil involving the giant spider monster that passed himself off as human. Results in a really horrible, horror-laden scene where a teenage girl gives birth to an overgrown spider creature in the school restroom, which then lunges at her squealing "Mama!"
The Running Man segment from Meikyuu Monogatari is pretty unsettling in its own right. The slowly accelerating heartbeat you hear in the background at the beginning, the dark character designs and the idea of telekinesis to kill off other racers don't help either. Top it all off with the ghosts of previous racers he murdered haunting him and Zack Hugh undergoing a Super Power Meltdown and the picture is gruesomely perfect.
Redda of Mon Colle Knights wears a creepy red death mask that covers his sexy Bishōnen face and loves spending his time driving people to suicide and especially subjecting things to transformations in disturbing, gruesome, and splooshy ways. One part of his Evil Plan traps Rockna within the neck of Dread Dragon, and suffice it to say, thanks to him, she was actually this close to getting slaughtered in a horribly disgusting way. And that's not all, the way he creates the Doomsday Dragon in order to resurrect Oroboros by reviving Dread Dragon and having Oroboros give it a Chest Burster itself is truly enough to freak the audience out. Nevertheless, the Gag Dub toned him down and edited some scenes.
Most (if not all) of Mononoke, what with the room of dead babies and the shamisen playing fish-person who makes you live out your worst nightmare.
MPD Psycho: There is at least one instance per chapter (there are 14 volumes (9 in English), but it drops off for psychological trauma in later chapters), but one of the stand-out moments of horror for the series was when the protagonists investigate a case where a serial killer was using the brains of his victims like grotesque flower pots. Made even better by the fact that up until he buried them, the victims were still alive while the flowers were growing.
How about the First Chapter, where the main characters girlfriend is mailed to him in a styrofoam box missing all her arms and legs? Oh, and she's still alive.
When Broken Bird Utako is introduced she is first heard as quiet sobbing coming from the apartment showers. After a frightening (for her) first meeting with Daikichi and Kana, they find she had been living on the streets before moving into the apartments and she becomes their new friend. Then Daikichi gives us this little expository gem, "Apparently while looking for work, she was led to an office and made to sign some contract written in some foreign language she had never seen before. And she hated it because she feared the big men and the cold showers and the dark little room..." Thank you for that gut-punch, Tanaka-san. (Fortunately it is never expanded upon because we really do not want to know and her life turns around for the better.)
Kana's description of her "life" after her suicide, sinking into the walls and thinking and wondering. And thinking. And thinking, until she lost all sense of who she was and where she was. Then at last she pulled herself together, left the walls, and wandered all around her deserted, rotting apartment, looking to see if anyone had come, until she gave up and went into the wall again. She spent years like that, all alone, trying not to go mad.
Gargoyle from Nadia: The Secret of Blue Water...First off, he wears a creepy, expressionless mask all the time. But that's not where he really gets scary, no. He kills people and CHILDREN for no reason whatsoever. He even kills people's pets, these pets can't hurt him or tell people what he's doing, but he kills them anyway just to make the people suffer. When Gargoyle attacks the Nautilus, Captain Nemo has to seal up an area of the submarine to keep gas from getting all around the ship and killing everyone. Some men, including Jean's new friend Mr. Fait, are sealed up in the room and will die, but can't be let out because the gas would escape and then everyone on the sub would be killed. All the characters are outside of the door and Jean is very upset and Mr. Fait is comforting him, saying he's accepting his death. Then, quickly after, he's screaming, shouting that he's too young to die, and there's so much he wants to do, all while the rest of the crew, including Jean, can hear him.
The most infamous examples would almost certainly be Hiroko being raped with a test tube by sadistic bullies and the leader of said bullies getting a deadly taste of her own medicine from Hiroko's shadow dragon. Oh, and if you think the anime's bad enough, the manga it's based on gives it a run for its money. Poor Norio...
Noir: The interrogation scene in episode 8 is very disturbing, mostly just because it just implies instead of showing. That and the screams are some of the most realistic sounding screams in anime.
Altena is creepy in the way she acts throughout the series and the way they imply how she raised both Chloe and Kirika by mind raping them, plus add in both her flashbacks they really show how screwed up she is and how she came to have the beliefs she held.
Also Kirika, while definitely very Moe and someone you just want to hug, whenever she goes into noir mode, especially near the end of the series, she becomes very creepy and scary; those eyes of her she has between episode 22 to 25 are a very scary sight.
Now and Then, Here and There was based on reports of the Rwandan genocide, and man does it show. In a subversion of a classic Ghibliesque "Kid Hero in a strange fantasy world scenario", our hero finds himself in an apocalyptic wasteland of chronic thirst, a literally insane warlord ruling with an iron fist, Child Soldier-hood for the boys, and child rape camps for the girls. There are supernatural elements in this Crapsack World, but do you really need them when you have most of the all-too-real curses that make life hell for all too many people in the real world? And where many entries on this list finally stop, this show keeps on bludgeoning you until you're an emotionally shattered wreck sobbing in the corner.
The manga Parasyte, by Hitoshi Iwaaki. Parasitic, shapeshifting aliens come to Earth and take over human bodies, played for all the Body Horror it's worth.
Pikadon, a short film about the Hiroshima bombing. It's obviously quite graphic, and certainly a Tear Jerker, but the lack of dialogue, music and animation style really vamp up the creepy factor.
Volume 2, Episode 4 of Presents, "Whatever Your Heart Desires." A girl ends up getting whatever present she wants, and due to her greed, selfishness, and paranoia, it ends up killing a boy who loves her. Where this goes above and beyond is that we never find out how or why this is happening. Kurumi doesn't appear once in this story, and beyond using presents, it doesn't seem at all like her usual tactics.
Pumpkin Scissors, where at one point the man with the flamethrower was part of a crew who were told that they had protective fluid in their suits, to keep them from getting fried by their weapons. They didn't. He goes on to be trapped inside the suit, unable to leave without dying, and apparently is cold, except when burning people. And then there's the scene where it actually shows those soldiers getting out of their suits, only to have their skin burn and peel off in large quantities, all the while they scream in pain.
Master Happosai in Ranma Ĺ. He's an incredibly powerful martial arts master who sexually harasses every woman he can get his hands on, and who is living indefinitely in the home of former students who are too terrified to kick him out. He also regularly harasses and molests his students' daughters, the youngest of whom is sixteen. His character is played for laughs in the series, but imagine what it must feel like to be a young teenage girl who has to witness your father cower helplessly before a man who victimizes you at every turn in your own childhood home, sometimes even sneaking into your bedroom at night.
Rozen Maiden has a scene when a half-completed (sentient) doll burns away in flames.
Robotech had dozens of EyeCatch segments for it's commercial breaks, and most of the major characters voiced over at least one eyectatch. The most creepy of them all was one by what is probably the voice of a bioroid terminator against a scene of one of Dana's nightmares (a cadaverous hand reaching out to grab her). The two parts of the voiceover were: "Robotech will return...and so will you.". When coming back from commercial, "Robotech is back...and I'm watching you." Make of that what you will.
Mostly anything involving the Peacemakers in Scrapped Princess. Particularly the giant black blobs they summon that eat people alive.
Shakugan no Shana has a chilling part of the nature of their world. If your power of existence is devoured by a Tomogara and you get turned into a "torch" by a Flame Haze, you become just a shell, a.k.a. an Unperson and will eventually disappear, with no one remembering you existed. Even worse is that this may have already happened, several times in fact to people they knew.
Shaman King: The anime has a couple of sources. The worst two come in the form of Faust VII's introductory episode, and the end of Yoh and Hao's first clash at the Great Spirits. The former has Faust phase his hands through Manta's body and reach at various internal organs, and all because Manta had said that he didn't think it possible to bring back the dead. The latter shows Hao doing worse to Yoh: He pulls Yoh's soul out and eats it. Instances were played, in full, in the English dub, despite 4Kids dislikes violent/creepy sequences. As horrific as the anime version of Faust and Manta is, the manga is even worse. There, Faust vivisects Manta alive. To full view of the reader. Just because he was curious how someone as small as Manta looked inside.
Shiki had a quite a bit of this from the very beginning, but chapter 18 took it to new heights when Ozaki dissected his fully conscious wife to test the limits of vampire regeneration.
Space Runaway Ideon has plenty to offer in this department. Unsurprisingly, considering it's legendary for its Kill 'em All ending. And all the characters die terrible, violent deaths.
Speed Grapher has rather a lot of this thanks to the effects of the Euphoria virus. Those who are infected with this virus without dying are granted powers based around disturbing sexual fetishes, and the way several of them transform when they get particularly "excited" is bloody freaky to say the least.
The manga of Spice and Wolf includes a scene (imagined by Lawrence) of what would become of them if Holo's true nature was betrayed to the Church. She and two others (presumably Lawrence and the man he is presently working with) are depicted burning at the stake, clearly alive by the agonized scream Holo is making.
Imagine that Video Games have taken a turn where you don't need a controller or a keyboard to play, all you need is a helmet and living the life of a adverting hero isn't just a moving picture on a screen...Now take one game called Sword Art Online and have the creator of said game make it so that If you die in the game you die in real life...not scary enough for you? Okay you know how people kill for fun? They're playing this game too and they made a guild where that's the ONLY type of person that's in said guild...Oh and you're probably saying "I have these awesome Skills, I can jus-" they have a means to paralyze you and kill you as they please...Not so simple now is it? Ya know what lets make it ever more complected, the game has a system that can pretty much label anyone as a Player Killer, A gem above every Players heads Green Means "He's a good guy He hasn't killed anyone" Orange Means "Oh he killed a guy...probably in self defense" Red Means "He's killed a bunch of people"...you know how in real life if you're involved in a murder you're charged with "Assisted Homicide"? unless you actually killed the guy...your gem won't change. Hey here's more the game uses your actual face so let's say you stopped some guy from killing a player to get his jolly for the evening and he wants revenge but OH NO the games clear everyone will be logged out...he can recognize you in public and kill you in your sleep...Fun game wouldn't you say?
Tales of Vesperia: The First Strike had some frightening moments of its own that would give its viewers the creeps for years; First off, take a look at the black and red tentacle monsters that are attacking several civilians that were just near the bridge to Shizontania. Then wait until you see one of the guildmen get dragged along the grass and killed along the way, and then see for yourself a tentacle monster in control of Lambert and two other dogs attached to its edge. And if that isn't bad enough, just wait until you see a rain of human blood from another of the guildmen falling on Hisca and one of the other knights. And Hisca's appropriate reaction to the blood spilled on her get-up and her body is truly frightening indeed. Bonus points for doubling as a Tear Jerker in the end when Yuri is forced to pull off his Shoot the Dog moment of killing Lambert and the other dogs along with the tentacle monster in order to protect Hisca and the others.
The latter part of Texhnolyze gets pretty disturbing. The show's second major villain is insane with borderline- Psychopathic Manchild tendencies; and he first convinces the citizens of Lux to discard their biological bodies to become cyborgs, arming them with Death Rays which kill anyone unfortunate enough to get hit by them, and then later he kills Ran, the series' resident Mysterious Waif, and puts her head on one of his statues. As if that isn't enough, he also reveals that the reason for his insanity was because his familywas selectively inbred. Oh, and the cyborgs? The source of power for Texhnolyze is ultimately shut down, so they end up frozen in place, unable to move at all. And at least a few of them are still conscious at the time.
A particular scene from the first episode has an incredibly gruesome anal rape and death. This would not be so bad except for the astonishing amount of blood, the horrible, horrible imagery present, the fact that the guy raping the other is easily twice his height and four times his weight plus the sound.
Some of the content in later episodes isn't much better. Two episodes after the event, said fat guy's BishōnenCasanova son (who is thinner than he is) splits a gangster's face open by slicing his face twice with a knife. Sure, they may have cut away before it got really gruesome, but still, it deserves to be up there.
Anything penned by Tsutomu Nihei qualifies and then some. The man's really really good at communicating Body Horror across a visual medium and he has tendency to waltz right through the Uncanny Valley.
Toriko, a cooking/fighting manga manages to come here during the Ice Hell/Century Soup arcs. Why? Bogey Woods and Tommyrod. Bogie Woods has 4,000 bones and 4,600 joints, capable of twisting and contorting himself in inhuman ways. But one of his most common techniques is 'lodging', where he enters a human and uses it as a 'shell', controlling it as a puppet from the inside. And he has nothing on Tommyrod, who can rapidly grow and launch a variety of deadly bugs out of his mouth, a mouth that is filled with razor-sharp teeth.
Oh, and they're just two members of the Bishokokai, the Big Bads of the series. And it gets much, much worse. Granny Chiyo...has the most disturbing smile when she stabs Master Chin...
Her method of fighting, which involves completely removing all the flesh off the bones on parts of her opponent's bodies faster than they can perceive. She's so fast she completely removed all the flesh off an opponent from his armpits to his hips so fast he didn't even realize it'd happened until she pointed it out to him.
While a bit over the top, has some pretty gruesome imagery, along with some of the most truly despicable villains ever put into a 1980s anime.
The manga is even worse. In the first chapter alone, you see tons of elementary-school-aged children die in brutal ways (they were all trying to escape their crumbling school during an earthquake) and people burned alive by an erupting Mount Fuji. Also, the fates of Miki Makimura and Ryo Asuka (aka Satan) from Devilman. Miki had been brought back to life and both characters are now limbless and forced to be the Slum King's sex slaves. And that's what Satan wanted.
Welcome to the NHK ends what's a pretty silly two-episode plot on MMORPG addiction by dramatizing the main character at 50 years old, still mooching off his parents and addicted to the same MMO. Still having done nothing with his life, his elderly parents write his life off completely before the story fast forwards, they die, and he's done for. Though this is supposedly played for laughs, it's a real Adult Fear a lot of people, who would find the Family-Unfriendly Aesop to be disturbing.
