Bleach is known for its massive doses of Fanservice for both guys and girls. However, this trope takes over many times as well:
Towards the end of the Soul Society arc, Mayuri is seen completely nude and dripping wet which reveals he's actually a bishounen underneath all that weird clothing and make-up... or he would be if not for all the scars criss-crossing his body, his missing ears and the realisation that the reason why he's dripping wet is that he's still reforming from the liquid state he'd transformed into to avoid being killed by Uryuu.
From the waist up, Harribel's clothing was extremely revealing with a top that barely covered her breasts but which covered her lower face entirely. When she unzips her top, she may expose her breasts but it's the demonic, skeletal jawline that grabs attention. While in Resureccion, she's a barely clothed stunner, but when captured by the Vandenreich, she's left hanging unconscious by her chained wrists, covered in blood and with spikes pinning her ankles to the ground - and suddenly her nakedness makes her look more like an abuse victim than fanservice.
Magical girls are cute, girlish and tend to wear teasingly suggestive clothing... that includes Charlotte Cuulhourne whose Resurrecion includes an item of clothing that is half-jockstrap, half-tutu. His appearance leaves Yumichika uncertain whether to laugh or cry. He settles for laughing. The fanbase is equally torn, and not everyone makes the same choice as Yumichika.
Orihime, for all of her "fame" as a Miss Fanservice, gets hit with this several times. Ulquiorra forces her to wear a dress reminiscent of Disney princess gowns and does get associated with princesses by other characters. During her captivity, she's horribly mistreated with her clothing ending up as torn as her body.Later, she's captured by Nnoitra, who sticks his finger in her mouth to silence her - sticking fingers in the mouth is associated with Japanese pornand Nnoitra had made some rape insinuations previously, something that squicked out even the emotionless Ulquiorra. And as seen above, during the Lost Agent Arc, Kubo twists one of her classic Gag Boobs stances into a disconcerting scene that shows Tsukishima's sword slicing through her chest andher hair.
On one scene, the very beautiful Bambietta can be seen in a state of disarray. Her stockings are gone, her top is unzipped to reveal she's a Hidden Buxom, and there's a sheen of sweat on her face. However, the sight of her is viewed from the foreground drama of her boytoy being split in two as she cuts him in half. Then we get two panels after that which show a close-up of her chest and a shot of her trying to fix her skirt (and probably her underwear).
Similarly, Bambietta's friend Meninas is a Cute Bruiser with very frilly clothes and massive boobs. Too bad one of the times when they're specially on display takes place when she and the other girls get shot through their stomachs by Baz-bee.
Perfect Blue has a good amount of this. There's the rape scenes, the scenes where Mima is getting photographed naked (pubes and all), Rumi in the CHAM get-up, etc.
Along with the numerous nude scenes Rei has, perhaps the best example is the scene where the massively broken Shinji loses it and "confronts"a semi-naked yet comatose Asuka at the beginning of End of Evangelion. That scene eventually grew infamous enough that the manga quietly excised it for something equally disturbing yet not so icky.
In End of Eva, Rei nearly spent the entire time naked. However, every scene featuring her was paired up with her staring at the floating intestines of her clones; or her left arm randomly falling off while she's talking to Gendo because her AT field is failing; or Gendo placing his hand on her breast, immediately followed by said hand morphing through her body so he can place the Adam embryo that's grafted on directly into her womb; or going through some ugly Transformation Trauma to a giant, quasi-godlike being that sucked out everyone's soul, only to fall apart in the most disturbing ways.
After devouring Unit-00 with its pilot in the remake Evangelion 2.22 Angel Zeruel assumes the form of naked female torso and lower body - along with its original Angel upper half and two arms the length of its body.
Asuka has a Furo Scene near the end of the series - when she's in the middle of a terrible breakdown, claiming that she hates the whole world while clutching her belly, seemingly in pain due to period cramps. Later, she's seen naked in a bathtub; her cheeks are hollow, and she's very much crossed the Despair Event Horizon by now as she claims to have no will to live anymore. What little water there is in the bath appears to be red, giving the implication that she's just tried to kill herselfby slitting her wrists.
A couple of times in End of Evangelion we see Asuka wearing skimpy wear, daisy dukes and a tank top with close-ups on her chest and butt. Fanservice, right? Not when she's depressed and having a breakdown in the one scene and yelling at Shinji in the other scene while disturbing music plays in the background.
There's also Shinji's... complicated relationship with Misato. In one scene in End of Evangelion, just before she dies, she gives him a french-kiss and tells him "we'll do the rest when you get back". Keep in mind that she's 29 and he's only 14. And that it's followed by Misato's heartbreaking death and Shinji breaking down again. Yeah.
Revolutionary Girl Utena has numerous intentional examples, mainly for the purpose of deconstruction. Notably, with a certain amount of Fridge Horror applied, even scenes that are ostensibly very fanservicey can turn into this trope — especially when one remembers how young most of the characters are.
Anything involving the Akio Car in the second half of the series tends to have the same effect, for many of the same reasons. Notable scenes include Ruka and Shiori having sex in the back of the car, which is part of Ruka's plan to humiliate and discredit her, and Touga sexually assaulting his own sister Nanami in there.
From the movie: the scene of a naked Shiori gaining butterfly wings. While it's beautifully animated, it's what it represents that causes the Squick, mainly her hatred as well as Touga's hatred combining, and the fact that the scene is overlaid with a child/pre-teen Touga being raped by his adoptivefather..
Also from the movie: Anthy and Utena take turns sketching each other nude. In Utena's case she's extremely nervous throughout and covers herself up as soon as it's over, and then tells Anthy that it's only fair that she do the same. Anthy agrees and we get the standard Dress Hits Floor shot and her beautiful nude silhouette... only to see that Anthy has a giant hole in her chest where her brother stabbed her before killing himself! By the same token, the scene of Anthy and her brother turns nightmarish as soon as he puts drugs into her drink and proceeds to take advantage of her, only to panic when she wakes up and he realizes that she was awake the whole time, leading to him stabbing her and then Akio killing himself. Yikes.
In the movie-manga, Utena comes across a nude drawing of Anthy, which happens to be the only time in any version of the story that Barbie Doll Anatomy is averted. However, as Utena recalls her earlier conversation with Touga about the so-called "prince", a blood-like smear appears on the Anthy drawing, right between her breasts... and then the whole thing melts away and Utena learns about the movie-manga's version of Anthy's past with her brother, which plays out in much the same way as it does in the actual movie.
Finally, the light novels prove that even the most obscure versions of Utena aren't safe. The idea of a sex scene involving Touga may sound appealing on paper, but it feels downright wrong to read about him bedding Miki, of all people. The fact that there is extremely dubious consent on Miki's part makes the scene doubly creepy, not to mention that Touga is clearly trying to manipulate him into having a drive to participate in the duelling game. And it's even, uhm, worse when you see an illustration of this scene that has a naked Touga... and Miki's bare feet. ("OMG! YOU KILLED MIKI! YOU BASTARD!")
Most of the "fanservice", of which there is a large amount, in Studio Gonzo's bizarre action series Speed Grapher. This is partly due to the fact that it's based around people who have become the Anthropomorphic Personification of disturbing sexual fetishes.
Kagura Tennozou is a beautiful young girl with long legs and a cute, doll-like face... except that she's also the biggest Woobie of the whole series, so whenever she's shown in anything similar to fanservice, she's being physically/emotionally abused and/or downright molested. And sometimes, while wearing a very Stripperiffic white outfit. Not to mention, she's just fifteen years old.
Hiromu Arakawa used this for comedy in an omake - it showed us Winry's grandmother Pinako in a bikini, calling her the 'heroine of Fullmetal Alchemist', with the words 'anti-fanservice' underneath.
It's also played for drama many times, like Roy's Shirtless Scene showing his bloody and wrecked side after he used his fire powers to cauterize his own wounds, Riza toweling herself after a shower revealing the alchemy-related tattoo and the scars on her back, Ling taking off his shirt to bandage Lan Fan's arm stump with it after she mutilates herself to save both of their lives... but the undisputed champion must be the moment when Ed sees Al's fully naked but terribly emaciated body on the other side of the Door.
When Father obtains God, he turns into an incredibly hot, muscular man, this look cemented status in the Draco in Leather Pants fandom, but, in the Brotherhood anime adaptation... He keeps his old man voice, in a body that looks like Slave 23, aka Young Hohenheim. It's like the Brotherhood staff got word of the DILP status said chara had reached, went all "HEEEEELL, NOOOOO!!" and decided to invoke the trope at full speed.
Berserk may be the champion of fanservice that isn't. While the manga contains a lot of blatant sexual imagery, most of it isn't too appealing unless you're into blood-drenched demon rape.
Probably the worst example of this comes in Volume 13 where Casca gets stripped naked by demons before being raped and given a Forceful Kiss in horrific fashion by Femto, the Godhand who was once her commander Griffith, while Guts is made to watch it happen right in front of him. We're more disgusted by this single scene of the Eclipse than when everyone else in the Band of the Hawk gets savagely devoured by demons.
However, one moment in the manga comes close to that: Slan decides to appear to Guts in the Qliphoth because she's obsessed with him and his continuous struggle against the forces of darkness. She decides to do this by appearing in front of him completely naked and acting as though they're having sex. However, the body she's in is made out of the internal organs of the hundreds of trolls that Guts has just slaughtered, they are surrounded by blood and gore, and she's impaling him with her hair. Squick doesn't even begin to describe it.
In the sixth volume there is a page of Alessandro "checking out" his new cyborg's body that would only be sexy to either a very, very twisted reader or one who found the page out of context.
It also has the lovely side shot of a half-naked Triela, after being found at the scene of her rescue from her "accident" (being the starlet in a snuff film). For worse, she's no older than 12.
And Claes in her underwear when she's having a medical test and it's revealed she has a heart condition. Again, we're talking about a girl under 12.
Gantz does this a lot, but it peaks in one manga, where a giant alien monster turns into a giant naked woman made up of smaller naked women. Women fingers, a fully expressive face made up of female bodies... and then one of the Gantz team tries to have sex with it in the mouth.
Welcome to the NHK features several nude scenes, but almost all of them are rather distressing borderline-Loli rape-fantasies from the mentally disturbed hero. In the original ending, in which the scenes are played out by the physical manifestation of his insanity - a grey demon-imp-creature with an excessively masculine voice wearing a pointy nightcap.
A lot of the nudity in Mnemosyne is this, from Rin being chased while half-naked before being blown away in a messy and disturbing manner, to her being tortured to death by a cheerfully sadistic research scientist who happily cut her clothes away before piercing every inch of her body and then bashing her brains in with a large club. Immortality has its downsides.
There are plenty of scenes taking place in various red-light districts, often featuring startlingly bold frontal nudity and scenes of sexual content. These couldn't possibly be any less erotic, because they're all drawn with unflattering details intact — and the actual prostitutes and strippers we see make it clear just how degrading and sleazy this is.
Also, there's the flashback sex scene between Eva and Roberto. To make it even more squicky, it's entirely from Eva's POV, meaning the entirety of it is spent focusing on Roberto.
The nudity scenes in the Black Jack OVAs tend to be of this sort.
When Michelle goes full frontal, it's not for the sake of a sexy shower scene so much as it's to show how much her body has deteriorated from a few weeks ago. In fact, the sight of herself in the mirror this way is enough for her to reach for the razor blade.
The greatest example is in the Ninth OVA 'The Carbuncle' when a mysterious female serial killer is revealed to be Black Jack's male patient, who suffers from a face shaped tumor on his stomach and is presumably being controlled by it. 'She' rips off the blanket covering her naked body... to reveal numerous face shaped tumors all over 'her' arms, stomach and torso, all of which laugh evilly along with 'her'.
There are similar examples in Say Hello to Black Jack. When a person is shown naked, it's often an elderly person or a cancer patient drawn with icky details.
The Ping Pong Club is another example of this; ostensibly an ecchi series, the unattractiveness of both the art and the teenage male characters' personalities turn multiple fetish cameos into "ugh" moments.
Chise spends a lot of time naked, and near the end there's a remarkably graphic and surprisingly well drawn sex scene between her and Shuji. It's in such a context that you may have trouble even seeing it through your tears. And then at one point, her arm falls off during coitus and she has to reattatch it. They keep going.
This is preceded (at least in the manga) by two equally fitting sequences: the scenes of Fuyumi's tryst with the 13-year-old Shuji and Shuji's final sequence with Akemi. After a particularly devastating enemy attack and Chise's counterattack, Shuji finds poor Akemi on her deathbed, bloodied and broken, where she confesses that she has loved Shuji for a long time, and asks him to look at her naked and to touch her breasts even as her injuries sap the last of her strength. It's a brutal mix of Squick and Tear Jerker.
At some point in the manga, Yoko takes a shower that shows us her beautiful body in all detail. However, said Shower Scene is a heartbreakingShower of Angst coming right after Kamina's death in battle. Yeah, we're really gonna oggle her when she's like that. For worse, there was a similar scene in the anime... and it was less fanservicy.
In The Movie, the sight of a naked Nia would be nice... except that she's getting tentacle-raped by the Anti-Spiral and then dematerializes.
Higurashi no Naku Koro ni has scenes with characters locked up in dungeons, chained to tables, and even bound to crosses. And Gainaxing. It all just contributes to the horror of how the former friends are about to brutally murder one another over some silly misunderstanding. The most obvious one has both Sonozaki twinswearing white robes and clearly without bras/panties underneath... but poor Mion is locked inside a dungeon, and she's being Forced to Watch how a Hate Plague-affected!Shion in full Yandere mode brutally crucifies, tortures and stabs their common friend Satoko to death.
The last episode of Tatarigoroshi-hen has a Furo Scene. Three things bad about this scene: 1. The character bathing is a little girl —namely, Satoko. 2. Her abusive uncle forced her to take a bath. A very hot bath. 3. She's being forced to (or rather, the Hate Plague is making her think so) count to 10,000 in the bath, and has been counting all night; when Keiichi breaks in, she is only halfway done with her counting.
Let's not forget the most common way Rika, a very young girl ( in looks) is killed throughout the series. She is usually found at the shrine, naked and disemboweled, complete with crows eating her remains.
And then we get to the first episode of the Rei OVA series, where the loving close-ups of Keiichi's crotch and rear while he's in a speedo are not going to go away without industrial strength Brain Bleach.
Robin spends two long arcs wearing lots of leather and a cleavage-baring blouse... while getting beaten bloody and quite literally "biting the curb" as Spandam tries to drag her away. In a scene that strongly resembles a rape.
Nami gets pinned to the wall by an invisible Absalom when she was taking a bath — again with the uncanny resemblance to a rape.
There are some characters who are Walking Shirtless Scene types. However, Hannyabal and Blackbeard, two very unattractive men, are among them.
New Kama Land. Sanji in a dress fighting while wearing bloomers. The man he is fighting is a gonk in a dress with fake breasts.
In a flashback during the Amazon Lily arc, we see a very cute-looking pre-teen girl with her hair in pigtails and wearing both Zettai Ryouiki and a midriff-baring outfit... That girl is a 12-year-old Boa Hancock◊; she's also in chains alongside her sisters Sandersonia and Marigold, and the three are utterly terrified since they're about to be subjected to years of cruel punishments, tortures and humiliations coming from the World Nobles.
Zoro with his shirt all torn up is pretty studly. Zoro with his shirt torn while dripping in his own blood and so hurt he can barely stand? Not quite as appealing.
Lampshaded and subverted in the Enies Lobby Arc. Old lady Kokoro offers to strip after seeing the reactions of the other men to Nami changing and gearing up for battle (the train they're on has only one room). Understandably they beg her to spare them the agony.
After the Post Episode Trailer in each episode there is a short, generally fanservice-yomake for a character who featured prominently in that episode. The one for Akane Higurashi features a voiceover in which she's talking to her boyfriend Kazuya, who died in that episode, and the last shot fades from a picture showing her in her underwear to black, with her HiME mark glowing red in the dark, after she lost it, and her powers, in the same incident that took Kazuya's life.
Another pops up later in the series, when Shizuru undresses in front of Natsuki and lying down with her... except Natsuki's alsoasleep at the time, leading to a rather disturbing conclusion reached by Haruka and Yukino, who suggest that Shizuru raped Natsuki in her sleep. It is unclear, however, whether the shot of Shizuru disrobing is what happened or a reproduction of what Yukino saw with her powers.
Tsukuyomi went from a semi ditzy minor minion to a rather creepy Psycho Lesbian over the process of her second fight with Setsuna, which was actually closer to her almost raping her rival. Seriously, she was straddling Setsuna while giggling and begging her to "satisfy" her... and gleefully cutting Setsuna's sarashi chest binds with her sword!
A chapter settled in the Magical World had the fake Asuna attack an enemy, who attempted to disarm her destroying her clothes as usual. When she continues to attack him, he slashes her across the back, injuring her badly and leaving her lying on the ground in pain. Fake or no, seeing the main heroine lying naked on the ground in a pool of her own blood is quite disturbing.
Seeing the very cute Ako Izumi fully nude at some point turns into this because she's having Shower of Angst after learning that her dear "Nagi-san" didn't relly exist, and was just an aged-up Negi. Followed by a chance to see her friend Akira Okochi just as naked... while trying to comfort poor woobie Ako over her loss.
Kabapu at a hot spring, rendered in painful wrinkly disturbing detail.
An earlier volume has Kabapu relaxing at a pool with Miwa Rengaya; one panel focuses straight to his crotch, and the word balloon placement makes it look like he's talking from it.
A good chunk of the last episode of the anime also counts. Especially the part where Excel gets stuck in Hyatt's body and decides to feel herself up while naked... and promptly starts coughing up enormous amounts of blood and shriveling up into a mummy. Then there's all the stuff that goes on in the love hotel...
The Anime version of Hyatt in general can be seen as disservice, always being shown wearing tight or scantly clothing, but always being kind of disgusting (Blood, contagious disease, vampiristic aura etc).
Franken Fran: One girl gains a perfect tanned skin, only to find that it is made of cockroaches and eventually cockroach legs start to sprout out of her face. One old lady looks at her new and attractive body in the mirror, only to become a sentient blob of cancerigenous cells with eyes a few moments later. Another schoolgirl becomes a mass of meat before splitting into two copies of the girl.
While Ranma ½: had a lot of fanservice for both men and women, the occasional Genma in the shower scene probably appealed to neither. While his Stout Strength is due to having a build like a barrel compared to the litheness of his son, or even Soun Tendo, he is still a homely bald guy whose panda form looks bloated even in anime (which, for once, has a better design then the manga). In fact, it's mentioned that Genma's panda form is apparently fat and ugly even by panda standards. Episode 110 deserves special mention for its featuring Dominatrix Genma, complete with leather bustier, fishnets and whip.
Umisho is all about the swim team fanservice. Unfortunately, this includes the male team captain Ikamasa, who's an annoying, cartoonish blowhard.
In the Super Robot Wars Original Generation OVA, we are given a lot of opportunities of Lamia Loveless being restrained with cables, butt naked... while her personality is being drained and had it not been due to her robotic nature, she'd be a pile of goo in a short moment (this happens to a nameless woman they encountered before). Then you see her riding another robot, still strapped and butt naked. Except... she's Brainwashed and Crazy and trying to KILL the protagonists.
Aside from the so-far-unseen "horrible scar" on their bodies from their transformation, it has an attempted rape scene where the girl is like "whatever," a female monster literally made of tentacles, and naked twin sisters merged together. Nearly all of the female Awakened fall into this trope, with most sporting exposed breasts and bodies, but always at the center of a writhing mass of One-Winged Angel Meets Lovecraftian Superpower.
The Abyss Feeders are almost or stark naked, nicely endowed women...with their eyes and mouths sewn shut. They also eat you alive, little by little.
Ophelia's One-Winged Angel form, who is a hideous Lamia-like monster that was defeated by Clare, and after she concentrated her human self at the opposite end of her snake form in a squickyAlien-esque way.
We eventually get a look at the 'horrible scar.' It's not a scar, it's an open, very deep cut from their neck to their genitals held together with stitches that never heals.
Sebastian's sex scene with Beast, although visually, it's fine. The disservice here comes from how he's seduced her into revealing information to him.
Sebastian's torture scene in the anime. Consider that he is separated from his master Ciel.
In the second series, the flashbacks of Alois being sexually abused by the previous Earl Trancy were definitely this. In episode one, Alois is naked in bed with the Earl. In episode 8, Trancy is naked in a bath-tub with a sexy-looking Aloisin a red kimono acting all seductive. And in episode 9, Trancy is kissing the foot of the much younger Alois, and later Ciel's.
Eyeshield 21 gives fans of the male physique a lot of fanservice (fabulously fit athletes, yay!). Unfortunately, it also gives us the Running Gag of Ootawara's bare-assed farts. There's also the beach football team called The Sexy Queens whose skin tight outfits show off all their bulging... bulges. The outfits are also very easily ripped apart.
There is so much Fan Disservice surrounding Orochimaru that his actual evildoing doesn't compare to the amount of Squick he causes. He has a Shower Scene when his arm was suffering from severe necrosis because part of his soul was eaten by a shinigami. There's also the constant implications that he is a paedophile, what with his habit of seducing people with promises of power, and said people typically being mentally disturbed orphans of both genders under the age of 13, and wanting to take the body of his favourite one, Sasuke. Apparently it was intentional.
For that matter, quite a few villains (including a lot of Akatsuki) end up shirtless when fighting, but it's rarely a nice sight as it usually shows how completely fucked most of their bodies are: Sasori took off his cloak (with no shirt under it) which showed he turned himself into a puppet, Kakuzu's showed off that he's pretty much a living ragdoll, Pain's cloak getting blown off showed that his entire body is covered in those piercings, and if Danzo losing part of his shirt wasn't bad enough, being a very old man, it showed off in addition to his eye covered arm he has a human face on his shoulder.
Chapter 579 features Kabuto shirtless, which wouldn't be so bad seeing as how he's normally such a bishonen but at this point he's had quite a bit of Sanity Slippage following Orochimaru's death, he's fused with Orochimaru's remains and has a creepy scaly look to his skin as a result of the fusing process and going into Sage Mode.
In one Shippuden opening we see what appears to be a nude Sasuke. Yay, right? Not when you see him wrapped up in Orochimaru's snakes with Orochimaru's eyes watching the image.
The various openings for Zoku Sayonara, Zetsubou-Sensei contain a scene where Itoshiki-sensei and his stalker/student are falling through the sky, grasping for each other. They finally catch each other's hand and embrace in an intensely romantic fashion... at least, it seems romantic until you think about why they're falling - then it becomes not a little horrifying.
The Blue Seed "Omake Theater" 12. Case in point, Momiji's grandma going to town and dancing in this skimpy outfit. Complete with a scene with her flabby granny boobs flopping around while she dances. The outfit that would be total fanservice on any other female character in the series, combined with grandma's body... granted, many of these segments probably were intended to be silly, but this one is a cross between Crowning Moment of Funny and horror.
Also, Suzaku in a midriff-baring female cheerleader uniform in the Lost Colors game. It was hilarious to see Suzaku laughing and having fun with it, and he himself is Tall, Dark and Handsome... but he's got exactly the same torso problems as Lelouch (this time, you can see Suzaku's ribs!) and thus he looks more freaky then sexy.
Then we see that Rai, the game's lead character, is right behind him. He's also crossdressing... and his Anime Chinese Girl outfit includes HUGE and saggy fake breasts. Erm.
Darker Than Black has several scenes involving naked or barely-dressed Dolls that are more freaky than sexy. On another front, the OVA, in its grand quest to parody the entire series, gives us a rather ugly guy with the same "teleport out of your clothes" power the Sociopathic Fanservice Girl has.
We see a pale and beautiful young girl laying naked on the floor, her long black hair spread underneath her, neverously waiting for someone else. She is Tsubaki Kasugano, the future 6th Diary Holder, and she's actually terrified instead of just nervous - because she's about to be gang-raped by the male members of a Religion of Evil that keeps her prisioner.
In the anime it's even worse: Yuno is actually stripped down to her panties and held down by two of Tsubaki's followers. It takes a last-second save by Yukki to spare her the abuse.
Yukki and Yuno's sex scene, despite being rather prettily drawn, since one's a total Yandere and neither are out of middle school. Plus, she starts reaching for an axe right after the fact and chases him around in her underwear while wielding said axe.
Yuno in her underwear... with her parents' skulls.
Seeing the pale, pretty and dainty-looking Yukio Washimine nearly naked (only wearing an open school blouse and a pair of white panties - including quite the close-ups of her very shapely butt and legs) is really terrible, since Chaka has just beaten her bloody and stripped her of her school uniform, and is now gloating about how he's gonna sell her into sex slavery. It's little wonder Rock is furious when he sees the condition she's in.
In the first movie, Motoko Kusanagi is frequently naked, as this is the only way her Therm-optic Camouflage can work. This is far less sexy than it sounds, especially when you see her naked body rippling with massive muscles which tear through her skin and gib her from overexertion, during the movie's climax.
The view of a naked Tsuzuki when he's actually screaming in horror and being horribly mind raped.
Earlier, Tsuzuki having what looks like a run-of-the-mill shower scene... before he collapses in agony because of Satanogas's Demonic Possession.
In the flashbacks to Hisoka Kurosaki's backstory, his kimonofalls off and we get a nice Toplessness from the Back shot (bonus butt included). This is followed almost immediately by poor Hisoka's memories of being caught, raped, and then cursed to a long and painful death by Muraki.
Everything Muraki does has a strong chance of falling into this trope. Not only do we know early on that he's a pedophile and murderer, but the incredible amount of Ho Yay he aims at the main character becomes reallyreallyweird when we discover that his goal is to put his dead brother's head on Tsuzuki's body. And he appears to be turned on by all of his experiments, ranging from turning pop stars into vampires to feeding schoolgirls to demonic hounds.
About the last part... one of Muraki's clients is a pop star who looks rather cute and wholesome when she's onstage. We later see her with her long hair down and her blouse open, which shows us that she's better endowed than we thought. Too bad we find out about this when she has been turned into a bloodsucking Tragic Monster who acts like a zombie as she strolls around with blood dribbling down her chin...
In the manga, there's an arc where we're shown a Catholic schoolboy giving a blowjob to an unknown person... a few panels later, he's shown cleaved through the head, semen dribbling out of his mouth.
Also manga exclusive: Hisoka's father Nagare is being tentacle raped by a snake god. Using its tongues.
Narutaru uses lacy lingerie in the most unappealing way possible. First, the girl wearing such lacy underwear (sans panties in the manga, to make it worse) is Aki Honda, a 12-year-old girl. Second, Aki is possibly the most monstrousAlpha Bitch ever written, who has just crossed the Moral Event Horizon hours ago by violently raping another girl, Hiroko. Third, the guy that she's Ready for Lovemaking for is her older brother Yasuhito (which was bowdlerized in the English manga to make him simply her boyfriend), whom the half-naked Aki lovingly straddles while only in said lingerie. And fourth, she keeps it on after her disturbingKarmic Death... in which she's first raped, and then cut into half by Hiroko's Mon Oni, as punishment for all the shit she piled on her. ... Eeeeeep.
The original Cutey Honey manga had lots of nudity. Most of it was from nudity and was legitimate Fanservice, but there was also the Gonk bullies at Honey's school (hairiest breasts you'll ever see), Danbei (full-frontal even!), and a detective whose anus won't stop bleeding.
Wicked City is chock full of this. Renzaburou's beautiful one-night stand? She turns out to be a spider woman who tries to kill him right after they go at it, using her Vagina Dentata among her "weapons". The High-Class Call Girl that Giuseppe fondles? Another demon woman, who almost kills him by absorbing him into her through her ginormous boobs. The time we finally get to see Renzaburou's beautiful and badass partner Maki naked? First she's getting fingerbanged by a guy who's holding her down against her will. Then a giant worm demon mouth rapes her after exploding her clothes off. Then she gets gangraped at least twice.
Canaan deals two huge ones in episode 11. Pick in between Liang Qi wearing very skimpy and fancy lingerie as she first gets beaten bloody by Alphard (and she's enjoying it like whoa), and later suffers one Hell of a Rasputinian Death after trying to give 'self Synesthesia and horribly failing (which includes, among other things, a truly epic quantity of Blood from the Mouth); and the gorgeous but now completely broken Hakko stripping naked and having sex with her beloved Santana...'s corpse. Either way will be, like, ew. And in the second, it'll also be, like, SOB!
Keroro Gunso had Kururu in a bikini in one of the pictures on the thirteen ending song.
In the Magic Knight Rayearth OAV, the three Magic Knights appear naked within their mecha. Nothing can go wrong with three very pretty girls riding naked into battle, right? Add horrible bloody injuries as they fight, though, and it quickly becomes Squick of the highest caliber.
After War Gundam X's Lorelei Arc gives us a surprisingly subtle example. There's a beautiful woman with an hourglass figure and Rapunzel blonde hair, and we get to see her in the buff... so far so good, huh? Except that the poor naked blonde has been like this for 15 years, locked inside a capsule and in a forcibly-induced coma. There's no blood or fluids involved, but oggling such a beauty when she's likethat feels just... wrong.
There is a track on the official OST called Corset's Theme. This led to some fan speculation about who this mysterious Corset could be, but most everybody expected a hot girl like Panty, Stocking, Scanty or Kneesocks who wears a corset. Well, it's true Corset does wear a corset. Unfortunately, Corset also happens to be a male demon. An incredibly ugly male demon, and the Big Bad of the show to boot. Given Gainax's history of trolling fans, this confusion was beyond a doubt deliberate - especially considering that the theme has female vocals.
Episode 15 has a quite bit of it, what with all the nudity of a young girl like a not-older-than-8 Yuri who is about to be heavily scarred and possibly raped by her father.
The ending card for episode 17◊ features a very handsome-looking Tabuki, with his shirt open and his glasses off. The bad thing? He's actually leaning his head on a little girl's lap. And while we don't see her face, the little girl is pretty obviously Momoka. Aaaaawkward.
Seeing the panties of either of the very cute Motoe twins would be fanservicy... if one of the twins wasn't about to get her left leg ripped off by an Elder Bairn, right before being horribly murdered.
Then there's Kanako — who not only had several panty shots, but a full breast exposure when she was killed.
Kaoru Orihara stripping twice (one of them also including Kimono Fanservice). She's very beautiful, but both times we see her naked or partially clothed, are in regards to how she had a mastectomy due to breast cancer and is showing her physical scars to others (first to her boyfriend Takehiko, to break up with him; later to her friend Nanako, while explaining her backstory). We don't get to see that, exactly, but the context will get your eyes blurry anwyway.
Earlier, Nanako and Mariko took a bath together after returning home from Mariko's birthday party, which seems to be pretty friendly...if it wasn't for the fact that Mariko goes Yandere on Nanako and threatens to kill her when she wants to return home afterwards. Brrrrrr...
Also, in the anime we're fooled into believing that Nanako and Fukiko will have a Les Yay-tastic "moonlight swim". But then Fukiko goes into Ax-Crazy mode and almost drowns Nanako to scare her off, via hooking her foot under a log and then leaving. She only survives because Fukiko didn't mean to go for the kill and returns to her soon. The scene goes from prospect Girl on Girl Is Hot to utterly chilling in few seconds flat.
In Kannazuki no Miko, seeing Himeko with her school clothes all open and leaning against Chikane would be all kinds of Les Yay... if not for the fact that this happens when Souma arrives to Chikane's Big Fancy House and then finds out that Chikane has raped Himeko, and he wasn't able to prevent it. Made worse by how Chikane puts on the rest of her HUGE Jerkass Façade (so her plan won't fail) and then starts gloating about it...
Maka lying on a bed while wearing a schoolgirl uniform? Cute. Maka lying on a bed while wearing a schoolgirl uniform as she's being forcibly pinned down by a Giriko in full yandere mode who states that he's gonna rape her before killing her? No... just no.
In School Days towards the end of the anime, when things go to hell, Makoto is murdered by Sekai, whose panties are clearly seen as she does so and later sits in a pool of Makoto's blood. The scene where Kotonoha murders Sekai, cuts open her stomach and checks to see if she's pregnant while in a short miniskirt and Zettai Ryouiki counts as well.
In one scene Osanai has Paprika captive, gropes her, and tears off her skin to reveal a naked Chiba underneath who he attempts to rape before the Chairman shows up to try to kill the naked unconscious Chiba. Squick incarnate.
Also there's Andrea Cavalcanti, a charming deranged Bishōnen who gets a naked bath scene where we see him crush a glass and lick the blood from his arm. And let's not forget Danglar's Death by Materialism, or Héloise de Villefort, a Stepford SmilerYandere who gets naked and masturbates while thinking about the Count and the poison ring he gave her, which means she's schlicking to the thought of using that poison ring to kill her stepdaughter Valentine and her husband Villefort.
Andrea’s sexual assault on his half-sister Eugenie and his sex scene with his own mother. AUGH.
Hellsing: Seras is a Ms. Fanservice with big boobs which are nicely accentuated by her police uniform. This would be reason to Squee.. except for her battle with Zorin Blitz. She mind rapes Seras into seeing her childhood trauma, which consisted of her mother's corpse being stripped of her clothing and raped while she watches. Then Zorin slashes Seras's eyes, hacks off her arm, and stabs her through with her weapon. She's left crawling on the ground utterly maimed... and still in her revealing outfit.
Even worse is during her Mind Rape. Yes we do see her mother's bare breasts. We see them while a thug is raping her corpse.
Seeing the beautiful Sara Uchida naked should be a reason to squee, but not when this happens when she's forcibly stripped and pinned down to the floor by rapist Yakuza.
The Would-be sex scene between Taka and his boss's beautiful wife. First, this happens in Taka's flasbacks to his younger years, meaning he's barely a teenager and the lady is at least in her 30's. Two, young!Taka is in an Heroic BSOD state, with Dull Eyes of Unhappiness and completely unresponsive to the older woman's seduction attempts, which gives very creepy rape vibes. (And no, Double Standard: Rape, Female on Male doesn't happen here). Three and worse, the boss catches them, and his reaction is to grab his katana and kill his own wife right there. And last but not least, this flashback takes place when Taka is speaking to the same Yakuza boss, who is in a sauna and thus is almost naked, and he ain't exactly pleasing in the eyes.
The only sex acts in Rainbow that aren't offscreened are when old, fat, hideous perverts rape terrified minors. (Notably, when a younger pervert of average weight with no obvious deformities rapes a minor, it's offscreened—clearly, the creators wanted to avoid even the possibility of arousal.)
In Freezing, the sight of Elizabeth Mably in her underwear should be quite nice. But it's not when she's actually being subjected to a massive session of Electric Torture.
Not to mention, the very beautiful Satellizer/Satella gets several scenes where she's physically/sexually harrassed and has her clothes either terribly damaged or forcibly taken off her. And then we recall that she actually was molested by her half-brother in the past...
Samurai Deeper Kyo's Hishigi is very attractive. However, the one time he takes off his shirt, it's this because he's covered in Devil Eyes.
Vash the Stampede from Trigun has one of these moments. Normally, Vash is dressed up in a badass red coat. His face can go from highly bishonen to manly protector quite easily. His body shape looks like he would be sleek and muscular under the coat, and therefore somewhat attractive... In Episode 18 of the anime (or the first chapter of Trigun Maximum, for the manga readers), Vash is in hiding using a fake name. One day, some bandits show up and demand the usual for bandits in Trigun: money and vengeance. Vash requests that they leave; the bandits reply (jokingly) that they will leave if he strips naked and acts like a dog. With only a moment of hesitation to extract a promise from them that they will really leave, Vash rips off his clothes... and reveals a mass of ugly scars that completely cover his body, huge metallic stitches, flecks of dried blood, and horrible wounds, including the prosthetic that replaces his left arm. Even the bandits looked shocked at the sheer amount of scar tissue... and then Vash is not fussed, and actually makes good on acting like a dog, until the bandits themselves are screaming for him to stop.
In Saint Seiya, when our hero reaches for the Pope aka Gemini Saga, we get to see his until-then covered face clearly — and he's a really beautiful man. It quickly turns into this when he suffers a massive Split Personality Takeover: Seiya undestandably gets scared and tries to attack him, which only destroys the robe he's wearing so Saga ends up naked, in the shadows. Yeah, he dons his armor a few seconds after, but seeing this naked, gorgeous and completely unhingedPretty Boy in the dark during that brief scene is much more intimidating than sexy.
In Shin Getter Robo: Armageddon, Kei is seen floating naked with Go inside Shin Dragon for an Out-of-Clothes Experience. Both are pretty good-looking people, but considering this particular continuity makes Kei into Genki (once the Cheerful Child) and Go into a clone of both Professor Saotome (Genki's dad) and Michiru (Genki's dead older sister), it's not exactly fanservice.
New Getter Robo: Benkei... too many times. Crouching over Ryoma with his robe on, landing in the Bear jet with his ass facing towards the in-cockpit camera after Saotome pulls him in, making a commotion in the lab while naked, flashing Michiru because of some misunderstood advice from Ryoma (this one in particular ended painfully for him). Thankfully, the animators got tired of using the big guy to make our eyes burn after a couple episodes.
Rikako Oryo of Psycho-Pass might very well be a deconstruction of Schoolgirl LesbiansFanservice, since on initial appearance she plays all of the Yuri Genre tropes arrow straight and might as well be an Expy of Sachiko Ogasawara... but is in fact a Serial Killer, and the audience knows this, making anything she does on screen extra unsettling. The crowning moment has to be when we see her naked in bed with another girl who she's just gotten done killing.
Space Dandy: In episode 3, we are introduced to the cute and perky Mamitas (lookit those boobies!), saved by the heroes , the disservice arising with her transformation into the Deathgerian, with Multiboobage whom you definitely would not want to be looking at. Complete with chest-bursting.
In Kill la Kill, the relationship between Ragyo and Satsuki involves Ragyo frequently caressing Satsuki's body and even giving her a very intimate massage in the bath. The problem? Ragyo is Satsuki's mother which makes her behavior completely inappropriate. Add to the that the implication that this sort of sexual abuse may have been going on for years and that Satsuki's personality is a consequence of it and you have a deeply unsettling aversion of Double Standard: Rape, Female on Female.
Taken Up to Eleven when something similar happens between Ragyo, Nui, and the Brainwashed and Crazy Ryuuko (who is also Ragyo's daughter) in episode 21. Complete with Ryuuko kissing Nui. And let's not forget that the aforementioned Nui is an Artificial Human who not only was created by Ragyo, but also considers her creator as her mother — complete with calling her "Mama". OUCH.
In No-Rin, depraved, sex-obsessed, 40-year-old teacher Becky-sensei who likes to randomly undress in class is used exclusively for this purpose.
Highschool of the Dead. The female main characters are gorgeous, and there's plenty of Panty Fighter and Clothing Damage scenes. That's good for one side, but when you see those elements on schoolgirls who died being eaten alive and some of them while wearing their PE and Swimming uniforms, just to be brought back to life as zombies... NO. There's even some instances of female zombies giving a Full-Frontal Assault.
