'''{{BRAIN BLEACH}} WARNING''': Just ''reading'' about ''The Human Centipede'' could make you wish you hadn't. Those of a sensitive disposition should [[SchmuckBait stop now before it's too late]]. [[SincerityMode We mean it]]; the "centipede" here doesn't just refer to a human with too many limbs. Administrivia/YouHaveBeenWarned.

Still with us? Well, don't say we didn't warn you.

In 2010's ''The Human Centipede: First Sequence'' (directed by Tom Six), two young American tourists, Lindsay and Jenny, find themselves traveling through Germany when they [[MyCarHatesMe get a flat tire]]. They stop for help at the house of [[DoesThisRemindYouOfAnything Dr. Josef]] [[HerrDoctor Heiter]] ([[AwesomeMcCoolName Dieter Laser]]), a surgeon who specializes in separating conjoined twins -- and a man [[MadDoctor with a vision]]. We'll let you get a cold drink and a comfy seat before we share [[BodyHorror his vision]] with you. If you like to drink alcohol, make your drink a [[INeedAFreakingDrink stiff one]].




Ready? Here we go.

Heiter dreams of taking separate individuals and stitching them together to [[BodyHorror create]] a [[TitleDrop "human centipede"]] that shares a single digestive tract. Take a minute to let that sink in if you need to. For the sanity of our readers, we will not describe how he plans to accomplish his goal here, but to bottom line it: Lindsay, Jenny, and a JapaneseTourist named Katsuro have just become his first test subjects.

Billed as "[[AsbestosFreeCereal 100% medically accurate]]," ''The Human Centipede'' gained plenty of early attention from horror fans and sites due to its [[AudienceAlienatingPremise depraved premise]]. (Riding on a wave of graphic European horror films helped the film, too.) The film often receives a mixed reaction from horror fans who can stomach watching it: some believe it went to amazing lengths with its premise, while others feel it relied too heavily on BodyHorror at the expense of scaring viewers.

The film found enough success at festivals around the world to warrant a {{sequel}}. 2011's ''The Human Centipede II (Full Sequence)'', filmed and set in England -- where the ratings board {{banned|InChina}} the uncut version until the filmmakers cut almost three minutes of footage -- centers around a PsychopathicManchild named Martin who becomes obsessed enough with the [[ShowWithinAShow first film]] to try imitating it; however, this time the centipede is longer than three people. Tom Six says the sequel makes the original film look like ''Franchise/MyLittlePony''; judging by people's reactions to the finished product, the sentiment comes off as legit. While the filmmakers billed the first film as "[[DanBrowned 100% medically accurate]]", Six described the sequel as "100% [[ArtisticLicenseBiology medically]] [[SelfDeprecation in]][[LampshadeHanging accurate]]".

Six completed a third movie, ''The Final Sequence''; despite reports of [[http://www.joblo.com/horror-movies/news/the-human-centipede-is-falling-apart-tom-six-suing-actor-dieter-laser a falling out]] between Six and actor Dieter Laser, both Laser and Harvey return, but as different characters. It's set in a prison and Creator/EricRoberts, of all people, plays the prison governor. The film was released May 22, 2015.

The films somehow spawned a [[LighterAndSofter light-hearted]] porn parody, ''[[ParallelPornTitle The Human Sexipede]]'', and inspired the Season 15 premiere of ''WesternAnimation/SouthPark'' ("[=HUMANCENTiPAD=]"). Someone also got the bright idea to make a ScreenToStageAdaptation in ''WebVideo/HumanCentipedeTheMusical''.

!!The trilogy as a whole contains examples of:
* AndIMustScream: Well, you ''can'' scream... it's just that you can only scream up someone's ass.
* AxCrazy: The characters responsible for each centipede. No explanation needed.
* BodyHorror: Good ''lord''.
* ChewingTheScenery: Dieter Laser in the first film. In the third one, he doesn't just chew it. He pulverises it and digests it.
* CreepyCentipedes: Not the literal kind, but close enough, and far creepier.
** Also, the pet centipede in ''Full Sequence''.
* FleshGolem: Technically, since the titular human centipedes are constructed by sewing people together ass-to-mouth.
* ForceFeeding: The "head" of each centipede is definitely the lucky one in this regard.
* ForTheEvulz: Why else would you sew people ass to mouth?
* {{Gorn}}: Multiplied with each installment.
* IAteWhat: Goes without saying, really. Not that they're confused about what it is they're eating.
* KneeCapping: Victims are crippled this way so they can't stand up.
* NightmareFetishist: You pretty much have to be to enjoy the films.
* NoDeadBodyPoops: Surprisingly, played straight.
* SerialEscalation: The first movie has [[spoiler:three people sewn together ass to mouth]] and the sequel has [[spoiler:twelve people!]] The third one has [[spoiler:FIVE HUNDRED PEOPLE!!!!]]
* ShowWithinAShow: The first film is a film within the second film. The first and second films are films within the third film.
* TagLine: Which doubles as a RunningGag:
** ''First Sequence'' is "100% Medically Accurate".
** ''Full Sequence'' is "[[SelfDeprecation 100% Medically Inaccurate]]".
** ''Final Sequence'' is "100% Politically Incorrect".
* TorturePorn: One of the more prominent examples right before the genre went down the chute, with the latter two entries contributing to its decline.
* VillainProtagonist: Each protagonist sews people ass to mouth, so this is a given.
* WorldOfHam: Many of the actors are clearly having a good time with this, though the standout example is Deiter Laser.
* TheWormThatWalks: Inverted.

!!''First Sequence'' contains examples of:
* AllAnimalsAreDogs: Heiter attempts to invoke this with the centipede by trying to get it to fetch the newspaper.
* AndIMustScream: [[spoiler:Lindsay's ultimate fate, with Heiter and the other two members of the "centipede" dead, [[FateWorseThanDeath she is left stuck between two dead bodies]] with nobody to help her]].
* AssholeVictim: [[spoiler:Katsuro, right before he commits suicide,]] accuses himself of being this.
* BilingualBonus: "Heiter" is German for ''cheerful''. Actually, an awful lot of the film is in German and Japanese. Unless you have the DVD subtitles on or know those languages, you're kind of screwed.
* BodyHorror: Heiter goes into ''graphic detail'' on what the procedure involves. [[spoiler: The cheeks (of the mouth) [[GlasgowGrin are cut]] and grafted onto the cheeks (the other kind) of the person in front of them in such a way that the mouth is enclosed around it and that the person can't even breathe through it, and can't move their jaw without ripping the flesh. Some of the front teeth are also removed so as to facilitate the flow of feces between segments, as are the kneecaps so as to prevent each segment from standing up.]] Probably the only horror film where ''you don't even need to '''see it''' to be horrified''.
* BreakTheCutie: Lindsay and Jenny.
* BrokeTheRatingScale: Creator/RogerEbert ''[[http://rogerebert.suntimes.com/apps/pbcs.dll/article?AID=/20100505/REVIEWS/100509982 refused]]'' to give the first film a rating. To be fair, he has done so in the past, for films like ''Film/PinkFlamingos'', where rating a movie would be pointless, as a director or prospective viewers couldn't possibly care about it.
* CrackFic: ''FanFic/TheHuemnCeniped2TheHumenMilipede''. Perhaps the author went insane after watching the film.
* DangerousKeyFumble: Lindsay ''deliberately'' drops the keys (for some reason) after locking herself in the [[MorallyAmbiguousDoctorate doctor's]] bedroom. She then realizes what a dumb idea this was, when the doctor then appears at the window with a tranquilizer rifle.
* DaylightHorror: Once the operation is complete, the film gets very bright and sunny visually.
* DespairEventHorizon: Katsuro finally crosses his after failing an escape attempt and being overcome with guilt, [[spoiler: slitting his throat with a shard of glass.]]
** Jenny's hysteria over her ordeal climaxes right before the operation as she's being sedated, with her devolving into terrified sobs and [[IWantMyMommy pleading for her mother]]. Once the operation is complete she is noticeably subdued in contrast to Lindsay and remains consigned to her fate up until [[spoiler: her death.]]
* DevelopingDoomedCharacters: The {{decoy protagonist}}s that the film opens with are not only horribly written characters, but also horribly acted. Not that you wish the horrors they later endure on them, but they're ''very'' annoying and unsympathetic. At the very least, you're thankful when the surgery leaves them voiceless.
* DoesThisRemindYouOfAnything: An insane German scientist wishes to try a potentially-deadly and BodyHorror-ridden experiment on live, human subjects. Whose first name is [[http://en.wikipedia.org/wiki/Josef_Mengele Josef]]. It doesn't help that his last name sounds almost like [[UsefulNotes/AdolfHitler that other Josef's boss]].
* DrivenToSuicide: [[spoiler:Katsuro.]]
* FanDisservice: Lindsay has some lovely breasts, but the first time you get to see them is also the first time she feeds after the operation. Did I mention she's the middle segment? In general, you've never had less fun watching topless women on all fours.
* FauxAffablyEvil: Heiter has his moments. Especially when the power cuts out and he apologizes.
* FinalGirl: [[spoiler:Lindsay survives, [[FateWorseThanDeath though it may have been better if she hadn't]].]]
* HerrDoctor, MadDoctor and MorallyAmbiguousDoctorate: Heiter.
* HopeSpot: Lindsay's escape attempt. The film goes as far as to literally have her standing in front of the open window contemplating running out before she makes the [[IdiotBall foolish]] decision to go back for Jenny.
* IdiotBall: Passed around many times, by both good and evil characters. Some examples:
** [[spoiler: Linsday, after freeing herself, dragging Jenny out of the house at a snail's pace instead of running to get help.]]
** [[spoiler: Katsuro not killing Heiter when he was down and had the chance.]]
** [[spoiler: Heiter flipping out about the police's accusations, taunting them about not having a search warrant, then jokes about having a torture den in his basement. The writer clearly left no room for guessing as to what was going to happen next.]]
* JapaneseTourist: Katsuro.
* KillEmAll: [[spoiler:Everybody but Lindsay dies.]]
* KillTheCutie: Jenny. [[spoiler:May or may not be the case for Lindsay.]]
* LeftHanging: Considering that there should have been some police backup the very same day (since two cops didn't report back from Creepy Guy's home), it's odd that there's no mention of Lindsay's fate.
* NightmareFetishist: Heiter is strongly implied to be getting off when Lindsay, as the middle segment of the centipede, is "[[{{Squick}} fed]]" by Katsuro.
* NothingPersonal: Heiter tells the truck driver "Don't take it personally" before killing him for "not matching".
* ObviouslyEvil: Heiter, good ''lord.'' Even Dieter Laser himself admits that he has an ideal "villain face".
* PlotHole: How did Heiter get the centipede out of the basement/OR if all he has is a spiral staircase? [[spoiler: This becomes quite an issue when the centipede attempts to escape.]]
* RecycledInSpace: The film is ''Film/HostelPartII''... with even more {{Squick}}!
* ShownTheirWork: The director brought in a surgeon to consult him on how a "human centipede" would function in real life (hence the "100% medically accurate" disclaimer), including suggesting that it would be able to survive ''for years'' with an IV drip to provide fluids and nutrients. This trope may also explain why the centipede [[spoiler:doesn't last long -- almost immediately, Jenny starts dying from blood poisoning]].
* StockParody: It's well on its way to this.
* TearsOfJoy: Heiter, [[spoiler: once... oh dear god... once it's complete.]]
* TooDumbToLive: Jenny & Lindsay, rather than staying on the road like any rational human being, decide to walk into the woods (at night) in the middle of nowhere Germany.
** In his review, Creator/BradJones points out that given how ObviouslyEvil Heiter was, it was incredibly stupid of the women to accept drinks from an open container from him.
** Or just driving on the flat tire since the car still ran. If they were smart, they would have paid for the insurance; so they could total it if they had to.
* VillainProtagonist: Heiter, a crazy, [[PuttingOnTheReich Nazi-esque]] MadScientist.

!!''Full Sequence'' contains examples of:
* AllJustADream: [[spoiler:The ending seems to imply that Martin simply daydreamed it all...]]
** OrWasItADream: [[spoiler:...Except the baby is still crying in the car all alone.]]
* AllPsychologyIsFreudian: Martin's doctor theorizes that he is obsessed with centipedes because they are a violent phallic symbol and that he associates them with being sexually abused by his father.
* AsHimself: Ashlynn Yennie, who played Lindsay in ''First Sequence'', appears as herself.
* AssShove: [[spoiler:Martin ends up on the receiving end of this when Yennie finally snaps.]]
* AssholeVictim: [[spoiler:A good portion of Martin's victims are people who have wronged him somehow: his mother, his psychiatrist, the rude couple at the beginning, the skinhead upstairs neighbor, etc.]]
* BodyHorror: Even worse than the previous film. Instead of actual medical instruments, things like '''''staple guns and duct tape''''' are used to [[spoiler:graft each victim to the next.]] As if that wasn't bad enough, [[spoiler:the villain forming the centipede ends up ''ripping out a girl's tongue'' to cease their screaming, and also ends up '''''raping the person at the end with his genitals covered in barbed wire'''''.]]
* CreepyCentipedes: Besides the titular abomination, Martin also has an actual pet centipede that plays this trope straight.
* DeliberatelyMonochrome: The director felt it was scarier in monochrome.
* DepravedBisexual: Dr. Sebring. He is seen getting a blowjob from a female hooker, and he also wants to ''rape Martin.''
* TheDogBitesBack: [[spoiler:Martin, especially in the scene with the rude boyfriend at the beginning and later on with his mother and their skinhead neighbor.]]
** Then there's Yennie, who, in a fit of adrenaline-induced rage, [[spoiler: grabs the funnel Martin used to force-feed her earlier, [[AssShove shoves it into his ass]], before grabbing his pet centipede and inserting it into the funnel.]]
* EvenEvilHasStandards: A twisted version. [[spoiler:Despite his obvious insanity and cruelty, Martin doesn't actually intend to kill his victims. When he does do it, or thinks he does, he becomes very upset, tries desperately to revive them, and actually cries when he fails (or thinks he did, in the case of the pregnant woman). Whether this is because, in his own twisted way, he feels bad for killing them, or is [[PragmaticVillainy just upset they can't be used in his "centipede"]] is open to interpretation.]]
* FanDisservice: Martin strips all of his victim naked, including some fairly attractive men and women, though the setting and the context is utterly unsexy.
* JackTheRipoff: Martin's obsession with the first film inspires him to create his own Human Centipede.
* KillEmAll: [[spoiler:Martin shoots everyone after the centipede splits in half.]]
* LaxativePrank: [[PlayedForDrama Done to horrifying and]] [[NauseaFuel nauseating]] [[PlayedForDrama effect]], when Martin injects each of his victims with a laxative syringe, forcing each of them to have explosive bowel evacuations into the mouth of the unlucky person behind them.
* MorallyAmbiguousDoctorate: Dr. Sebring, Martin's psychiatrist, has a bit of this going on himself, considering he has sex with hookers and [[spoiler:wants to rape Martin, his mentally disabled patient.]]
* NightmareFetishist: Martin became sexually obsessed with the original film and resolved to create a Human Centipede of his own.
* NoSocialSkills: Taken UpToEleven by the mentally-handicapped Martin, who has poor hygiene, problems making eye contact, and is apparently nonverbal.
* SelfDeprecation: Whereas the first film is {{tag line}}d as "100% medically accurate", promotional material for this film flaunts it as "100% [[ArtisticLicenseBiology medically inaccurate]]."
* SequelEscalation: If the first film was too much to stomach, '''''do not''''' watch the second film. Not only are the means of assembling much more rudimentary and unprofessional, but there are more people involved. Additionally, the villain does some horrific things to his victims [[ForTheEvulz for basically no reason]]. In the words of the director, it makes the original look like ''My Little Pony''.
* SilenceIsGolden: Martin never speaks any actual words, and in the second half of the film dialogue is replaced by the cries and moans of the victims.
* SilentProtagonist: Martin never says a word onscreen. He is intimated to have talked and makes phone calls offscreen (we only see him checking his messages on his phone), so he ''can'' speak, but aside from some grunts, he otherwise is [[TheVoiceless completely silent]].
* TongueTrauma: Martin rips out Ashlynn's tongue with pliers after he gets annoyed with her screaming.
* VillainProtagonist: Martin, a mentally challenged pervert who is inspired by the original film to commit truly horrific crimes.
* WoobieDestroyerOfWorlds: To some extent, Martin is this. [[spoiler:He was sexually abused by his father, who went to prison because of it. And his equally horrible mother actually blames Martin for her husband's arrest and treats him like garbage. His psychiatrist Dr. Sebring pretends to be his friend but actually wants to sexually take advantage of him. And most people's first reaction to him, even when he hasn't done anything, is to insult and belittle him. While there is no excuse for the actions Martin takes, it's nonetheless easy to see how all of this can combine to finally make Martin snap and lose himself in grotesque fantasy, and want to [[MoralEventHorizon enact that fantasy]] on the people who've wronged him. By the time he actually sets to work, he's so deeply involved in his mania he also targets innocents.]]

!!''Final Sequence'' contains examples of:
* AlternativeForeignThemeSong: The theme song for the Japanese version is [[https://www.youtube.com/watch?v=-T1bRVplNA4 "Krazy"]] by Raychell feat. RICKY & RABBIE.
* AscendedMeme: Deiter Laser's character again screams "swallow it bitch!" though this time he's ordering Bree Olson's character to swallow his semen.
* AsHimself: Director Tom Six plays himself.
* AssholeVictim: The victims are all convicted criminals.
* TheBadGuyWins: Deranged prison warden Bill Boss not only succeeds in making over 500 convicts into a human centipede, but he also convinces Governor Hughes that making prison inmates into a human centipede is "what America needs".
* BodyHorror: Toned down from the last film somewhat (though still worse than the original), simply [[spoiler:stitching them from ass to mouth without grafting their skin to each other or removing their teeth and kneecaps]]. After all, prisoners have a finite sentence, and they eventually have to leave prison without disfigurement. The exception is for death row inmates and those serving life sentences, who get turned into a "Human Caterpillar" -- not only are they given the full surgery described above, but they also [[spoiler:have their arms and legs removed]]. Unrelated to the centipede are the [[spoiler: imported dried clitorises.]]
* BrandX: Bill Boss drinks Cirrhosis brand whiskey.
* ButtMonkey: Daisy. She's regularly sexually harassed and forced to fellate Bill Boss in exchange for getting her father out of prison. During the riot, Boss instantly locks her out of his office, and she is brutally beaten into a coma by the inmates. While unconscious, Boss rapes her and then has her integrated into the centipede for no apparent reason.
* DaylightHorror: The prison is located in a very sunny desert.
* EvenEvilHasStandards: Dwight, who suggests the idea for the centipede in the first place, still objects to Boss's various additions such as [[spoiler: removing the limbs of death row prisoners to form a "Human Caterpillar" and including an innocent Daisy in the centipede.]]
* EvilIsHammy: Bill Boss. And HOW.
* GenreShift: This installment is a TorturePorn[=/=]BlackComedy, unlike the first two, which were just Torture Porn.
* ImAHumanitarian: Bill Boss eats dried clitorises and medium rare testicles.
* NightmareFetishist: There's one insane inmate who eats his own feces and actually ''[[TooKinkyToTorture wants]]'' to be part of the Centipede.
* OohMeAccentsSlipping: Dieter Laser's hold on his good ol' boy speech is tenuous at best, and his German accent reasserts itself anytime Bill starts yelling (in other words, almost constantly). Averted with Laurence Harvey, whose polite southern genteelness stays pretty consistent.
* PragmaticVillainy: Bill Boss plans to make all of the prison inmates into a human centipede. He kills two inmates that can't be used in the procedure, one because he has a stoma and another because he is disabled. Boss also finds a mentally unstable inmate eating his own feces and wanting to be part of the human centipede, but Boss kills him because he doesn't want anyone to enjoy being part of the human centipede.
* ReverseCerebusSyndrome: The third film is LighterAndSofter compared to the previous films. Not only are the victims unsympathetic prison inmates, there are way too many of them in the centipede to possibly take seriously, and the violence shown is so outrageously over the top that it becomes a farce. The actual surgical procedure is much closer to the original than the first sequel, as it is again performed by medical professionals. Furthermore, there's much more emphasis on BlackComedy then the previous films. Also, casting a prominent porn star in a main role and having "The Star Spangled Banner" playing over the end credits also tend to distract from any attempt at seriousness.
* SelfDeprecation: "I fucking told these movies would be shit and they are pure shit, literally. They stink."
* SelfParody: The film takes the concept from the first two films completely over the top, and mixes in an assortment of meta-jokes and memes.
* ShoutOut: There are references to the ''WesternAnimation/SouthPark'' episode "[=HUMANCENTiPAD=]" and the porn parody ''[[ParallelPornTitles The Human Sexipede]]''. Also, the inmate played by Akihiro Kitamura (who played Katsuro in the original) says that the film "occupies a world where the stars don't shine," which is a quote from [[Creator/RogerEbert Roger Ebert's]] scathing review of the first film.
* TooKinkyToTorture: There's one mentally unstable inmate who eats his own feces and ''wants'' to become part of the Centipede. Bill shoots him, as being part of the Centipede is meant to be a punishment, not something to be enjoyed.
* VillainProtagonist: Bill Boss, a racist and misogynistic prison warden who is inspired by the ''Human Centipede'' films to make all of his prisoners into a gigantic human centipede made of about 500 people.
* WardensAreEvil: Bill Boss. An unusual example in that he is also pathetic and the inmates do not fear him, despite his violent sociopathy.
