A3 fandom is particularly fond of making Homare Arisugawa a frail sub when shipping him with Hisoka. One popular way is to make him having physical ability equal to Itaru and incapable of carrying Hisoka. Hisoka is no bigger than Muku, whom Homare manages to carry on his back through a blizzard in Special Edition: Snowfall Street. Even then, in the official comic series, Homare has been shown to carry Hisoka on his back without a fuss. What makes this wimpification common is because of Homare's Hotel Compass backstage, in which he fails to carry some boxes, and people blow it out of proportion despite past and future stories show that Homare's physical ability is far better than they make it out to be. Homare is also made to be very needy and clingy towards Hisoka due to his expressiveness, as opposed to Hisoka's stoic Terse Talker nature, despite canon having made it clear that Homare is a capable and independent adult who may even forget to ask for help when he needs it.
Edgeworth could get this one a lot in the heyday of Ace Attorney fandom, especially fics pairing him with Phoenix, and it was as easy as trapping him in an earthquake. Some of these could make for compelling Hurt/Comfort Fic, but others found it too easy to take away his spine and turn him into a quivering mess of tears and Daddy Issues.
Apollo Justice to just about every male. He's a rather straitlaced character, but his relative inexperience in the field, his smaller frame, and his Obviously Not Fine approach to his feelings makes him a very easy target for ukefication. Later games expanding on his backstory and giving him more loved ones to see suffer only made the problem worse.
You'd think that Army of Two, a game that centers on teaming-up between two equally badass, equally competent, equally manly ex-Army Rangers who are now Private Military Contractors would be able to avert this trope. Unfortunately, what little Army of TwoSlash Fic there exists happens to have a significant bias towards making Salem (the slightly smaller member of the duo) the receptive partner in any sexual encounter. In all fairness, Salem's characterization is rarely derailed into attitudinal submissiveness, but he's still made the "bottom" in sexual encounters more often than not because he's shorter than Rios. Not to mention the Fan Art which makes Salem into a Bishōnen.
Bayonetta creator Hideki Kamiya was driven to publicly denounce doujin creators because of the number of grossly out-of-character fanworks that showed her bottoming to any random person. Since then, she has generally taken the power back.
This happens to three characters in particular in Bully:
Kirby Olsen is a Jock who plays wide receiver on the football team and is the youngest student in the school to receive a varsity letter. He also has a foot fetish. He regularly gets derailed into a whiny priss who'd rather go shoe shopping than tackle a nerd.
Derby Harrington is the leader of the Preppies clique and a very competent boxer. However since he doesn't like to get his hands dirty, he usually has his friend and dragon Bif Taylor do the fighting. This gets twisted until Derby's entirely helpless and relies on Bif for everything.
Larry "Peanut" Romano is Johnny Vincent's best friend and is actually hinted to have a gay crush on him. However, Peanut's no less willing to fight than the rest of the Greasers, and he has a chip on his shoulder over his nickname. In fanfic, he spends a lot of time being beaten up by Preppies and running to Johnny for comfort.
Danganronpa has a lot of this trope going on, especially for more vulnerable characters:
Makoto Naegi, The Hero of the first trilogy, gets this quite a lot in fanworks. In the game, he wears his emotions on his sleeves and then a fairly popular spinoff Alternate Universe Light Novel, if, cast him in the role of Distressed Dude. This, combined with the fact that both of his most popular love interests are The Stoic, resulted in the fandom taking this interpretation and running with it.
Kiyotaka Ishimaru is a Hot-Blooded and Brash person who isn't afraid to put himself as a leader, but in fanworks pairing him with pretty much any guy, he's submissive and can't hold off for himself.
Connor is the most obvious target of this in the game due to his brown Puppy-Dog Eyes, awkwardness, and tendency for awkward behavior, but fans forget that he's also the most skilled combatant out of the whole cast who can take down entire squads of trained soldiers with ease and is perfectly willing to defy Hank and the other humans he's supposed to serve. Not to mention he can be quite ruthless at times. Fans also have a tendency to exaggerate his more cheerful side to Keet levels, when in-game he's still quite aloof and barely changes his expression from a resting stoic face even when friendly.
Markus tends to get this whenever he is shipped with Simon. Although Markus is a powerful, charismatic leader who takes things to his own accord regardless if anyone agrees with his plans or not, he's reduced as some sort of scared little boy who can't do anything without Simon there to come by his side and scoop him up. Or rather vice-versa.
Disturbingly, Gavin Reed also tends to get this treatment in conjunction with a massive dose of Draco in Leather Pants. The game itself does nothing to indicate he's anything other than an utterly irredeemable Jerkass who abuses Connor and mistreats all of his coworkers due to petty arrogance, nor does it ever suggest he has any reason for it outside of pure Jerk with a Heart of Jerk, despite providing a Freudian Excuse to other similarly repugnant characters. Fans tend to portray him as a tragic Troubled, but CuteWoobie with a tortured past to excuse his behavior, incapable of seriously hurting anyone (even though he can hurt and outright kill Connor in some playthroughs). The wimpification goes double if he's being paired with RK900, who also often receives the Fetishized Abuser treatment and subjects Gavin to bucketloads of Romanticized Abuse in such works.
In Dissidia Final Fantasy, the character Firion is a largeHot-BloodedWalking Armory of a badass. He is also, especially in Japanese fandom, the Launcher of a Thousand Ships in a Cast Full of Pretty Boys, and he almost always bottoms. The end result is that Firion is very frequently transformed into a weepy uke. Now, what makes this interesting is that while all of the above is definitely true of Firion, he is also at the same time rather in touch with his feminine side—he's sensitive, fond of flowers, and displays more emotional vulnerability than most of the other guys. It's just also intensely exaggerated for Shipping purposes. It doesn't help that in Japan, surprisingly, despite his deep English dub voice, he is voiced by Hikaru Midorikawa. About the only one of his multitudinous common pairings where you can't expect ukefication is with Tidus, being that the latter's Keet is turned up to eleven and Firion becomes a sort of romantic Only Sane Man.
The wimpification of Dorian has reached such a degree that some circles go as far as to claim that his relationship with the Iron Bull is abusive based on Bull's significantly greater size, the fact that that their relationship contains at least some elements of BDSM, and because Bull responds to Dorian's smartassery by being a smartass back. This all apparently means that Dorian is a helpless wallflower that needs to be protected from the big bad Iron Bull, as opposed to the canon Necromancer Tsundere who wasn't afraid to tell off his father and his entire country.
This is bound to happen to the Inquisitor, particularly if they're not Qunari. Though the point of the relationship is that Iron Bull made it Safe, Sane, and Consensual with a Safeword and does not extend outside the bedroom, some bad fics tend to make it very wangsty as if having sex with Iron Bull makes the Inquisitor feel better.
Fenris is often drawn or written as a Tsundere, if not submissive and weepy, when paired up with a male Hawke or sometimes, Anders. His looks and tragic backstory are common contributes. But it gets reinforced with him telling Hawke "I am yours", how he tends to look at him with "sad puppy eyes", Uncle Gamlen commenting how he doesn't even need to guess which one of them is "the girl" in the relationship, and a Snarky!Hawke having the option to tell him how "it can be a lot to take in" after they had their first time.
Anders is also frequently turned into a weepy, clingy mess when paired with male Hawke, often using his past in the Circle of Magi as an excuse. While Anders is hardly the picture of mental health, this is the same man who is sharing his body with a demon and blew up a cathedral because he was fed up with the status quo. Quite a few players seem to have missed the conversation where Anders explicitly stated that he was not abused physically or sexually while he was in the Circle.
Pretty much every yaoi fic ever written involving Final Fantasy VII does this to either Cloud or Vincent. Yaoi writers seem to love taking the Iron out of Iron Woobie.
Pairing a character with Sephiroth is pretty much a guarantee that the character will be Ukefied out the wazoo. In less frequent Sephiroth/female character pairings, she is usually reduced to a weepy, ineffectualDamsel in Distress regardless of any canon badassery on her part. One exception is when Sephiroth is paired with Genesis. Then it's usually Sephiroth who undergoes the Ukefication.
Prompto gets it the worst of the lot, being that he's a short blond KeetBishōnen who kinda looks like Cloud Strife. He does have genuine self-confidence issues beneath his extroverted persona, but eventually overcomes them with a little pushing from his friends, only ever cries in the main game once (during a time when literally everyone else is too),can take and dish snark with the best of them, and is quite chipper about killing his enemies. And while the game states he's the poorest fighter of the team, it's only because he's inexperienced, not because he's physically weak. He's actually more muscular than Noctis, and is strong and skilled enough to beat enemy soldiers to death with his bare hands. However fangirls frequently gloss over this and exaggerate him into a spineless frail weepy mess and literal Damsel in Distress or an infantile Ingenue who can't even hurt a fly and falls apart without Noctis's constant validation, leading to hot steamy sex which frequently ends in Prompto becoming pregnant. They forget it's his job to protect Noctis, not the other way around.
Not that Noctis gets it so great in these fics either. His own canonical issues with inadequacy and shyness are ignored in favor of turning him into a bland Prince CharmingRelationship Sue to compliment Prompto's self-insert status. Or to contrast with how Prompto is often idealized by fandom, Noctis is frequently taken in the opposite direction and turned into a Fetishized Abuser who is abusive and controlling towards Prompto for fetish appeal reasons.
While Friday Night Funkin''s Boyfriend retains his cocky and foolhardy nature in many fan works, just as many works depicting him in a relationship make him more innocent and sensitive, sometimes making him more helpless in the process. This is especially true in works where his ambiguous history with Pico is a main focus; where Pico is turned into a violent/jealous ex-boyfriend or simply a coolheaded mercenary, Boyfriend becomes submissive and eager to rekindle whatever love they lost over the years.
Speaking of Pico, his personality, due to the very nature of Newgrounds culture, varies from person to person, but he's generally characterized as a hotblooded Heroic Comedic Sociopath. Works depicting him in a relationship post-2020, however, greatly emphasize whatever feelings he has left from the aftermath of Pico's School or his adventures overall, often making him a traumatized Bruiser with a Soft Center who needs a lover to heal him. There are a number of flashes that touch on the subject, but more often than not his self reflections are not as emotionally invested or reliant on a romance, and in one of his more notable fan flashes (Pico Epilogue) the trauma causes him to self destruct and almost commit suicide rather than turn to anybody for help.
Happens to DamonBaird in Gears of Warslash fics. After all, who cares about being in character when it gets in the way of hot sex?
Kid Icarus' Pit, ever since he was re-introduced to the gaming community in Super Smash Bros. Brawl, has been getting this treatment - while he was revealed to indeed be an adorable Keet in canon in Kid Icarus: Uprising, with the voice and appearance of a 13-year-old boy no less, often he's Flanderized into being a downright girly wuss with little sign of his Hotblooded nature. Especially when in Super Smash Bros. fanfiction.
Sora and Roxas, in Kingdom Hearts end up on the wrong side of this trope when they're paired up with Riku and Axel, respectively. "Naga Eyes" is a particularly infamous case.
Several of the Organization XIII members get this too. Here's a list of the worst examples;
Demyx and Zexion seem to be the biggest targets. They both get paired with all the other members, and almost always end up as the ukes. Zexion seems to be the bigger victim of this, seeing as how when he gets paired with Demyx he usually gets portrayed as the uke.
Marluxia is an unusual example of this, most Fan Fic that he's in portrays him as Camp Gay, even if it isn't Slash. It seems to be because of his pink hair and control over flowers.
Even Saix isn't immune! While most slash fics about him have him as the Seme, when he gets paired with Xemnas he becomes little more than a pet. Thanks to the discovery that both of them are possessed by Master Xehanort, the idea of any kind of sexual relationship between them becomes very creepy, regardless of who's on top.
Commented on, with other fanfic tropes, in Those Lacking Spines. There is an Ukenator 3000, and ukefication is mentioned by name. Quoteth Vexen as if it was a biological disease:
This state wipes the personality and demeanor of a victim completely clean, replacing it with one of complete and utter submission. This causes the victim to become weak, fluffy, emotional and utterly incapable of standing up for themselves, wanting only to be in contact with others to further spread the epidemic. It is quite frankly disgusting.
In a fair number of Cleon fics, Cloud tends to be written as the more vulnerable, gentle, ukeriffic partner, despite the fact that in the actual games, he's kind of a grim hardass; if anything, Leon has shown more emotion (occasional smiles, one or two open displays of worry, heartfelt proclamations of friendship that get mocked by the main character in a later game) in canon than him.
It's almost a Running Gag to subject Kyo Kusanagi to this trope when he's featured in yaoi doujinshii, particularly if Kyo's love interest is Iori Yagami. Even if we don't take Kyo's girlfriend Yuki in consideration, Kyo is actually Hot-Blooded and very proud, so he'd likely either be the one topping his Ho Yay partner or would do his best to get to top; seeing him twisted into an uke of the passive-aggressive kind is extremely OOC in itself.
Left 4 Dead 2: Oh poor, poor Ellis... What has being paired with a narcissistic, shady conman done to you?
The Hunter goes from snarling and tearing out peoples' intestines in-game to being downright cuddly in many fan portrayals.
Link from The Legend of Zelda franchise gets this rather often, a major factor likely being his nature as a Silent Protagonist and Bishounen on top of it. Must be a Hylian thing.
Garrus Vakarian and Thane Krios are often subjected to this in a semi-rare het invocation of this trope whenever they're paired with a Female Shepard. But due to Fan-Preferred Couple status, Garrus gets it worse than Thane does.
Kaidan often gets uke'd in fics with a Male Shepard. Despite the fact that he's a veteran Marine and one of the more badass biotics in the Alliance, writers will focus on his childhood issues and use his recurring migraines as an excuse for Hurt/Comfort Fic. That said, there's still no shortage of fics that wimpify Shepard himself. The majority take place after the Destroy ending naturally, but there are some that take place before.
In Mega Man X, the title character X goes through this a lot due to his pacifist leanings. X7 actually serves as something of a canon example when X, after nearly losing Zero in a previous game, actually refuses to fight at all for the entire first half of the game. This, incidentally, is one of many reasons why X7 is to this day considered the worst game in the series.
Solid Snake gets it a lot too, but since this is mostly a backlash against the idea above it's usually handled with a little more style with him — used more for Woobie appeal than Unfortunate Implications. Not always, though.
In Outlast, Waylon Park is a Badass Normal software engineer who breaks out of an asylum filled with rampaging killer mutants, narrowly escaping death and dismemberment multiple times. However his Nice Guy persona and the fact that at one point he gets stripped naked and strapped to a table so he can be made into a woman courtesy of a buzz saw to the genitals means the fandom turns him into the Uke for pretty much every other male in the game, often subjecting him to mental, physical, and sexual abuse. The most popular ship pairs him up with Eddie Gluskin (aka THE GUY WHO STRIPPED HIM NAKED, STRAPPED HIM TO A TABLE, AND ATTEMPTED TO CUT HIS JUNK OFF WITH A BUZZ SAW.)
Within the Overwatch community, this is a trend with any pairing that involves characters who are canonically supposed to hate each other. It doesn't help that the lore's staunch refusal to advance has enabled a status quo in which the villains have claimed most of the victories and hold all the advantages. Jack Morrison, who was the leader of the titular organization for a reason, will sometimes be reduced to a doe-eyed lamb whose only role is to be dommed by a pre-Reaper Gabriel Reyes. Likewise, in a female instance of this trope, poor Tracer also got hit by this pretty badly. While she is a sweetie, she is also an exceptional pilot and one of Overwatch's most capable agents, but her loss to Widowmaker in an early story cinematic apparently gave some people the impression that she's outright helpless and would happily play the innocent and submissive role to a domineering Widow in a borderline abusive relationship, allow herself to be belittled and mistreated around her, or — most humiliatingly — be her pet, thoughts which would all probably make the canon Tracer's blood boil.
This is especially glaring with the pairing of Zarya and Sombra, which frequently portrays the latter as aggressively having her way with the former however she wants, regardless of consent. Note that Sombra is one of the game's smallest characters, and her entire style of fighting both in gameplay and in lore revolves around her being a weaselly little minx who relies on stealth and cheating. Meanwhile, Zarya is literally a professional body builder and a frontline soldier who acquired her main weapon by ripping it off a tank.
With any pairing of Junkrat and Roadhog, this trope swings both ways. Junkrat is usually some vulnerable little angel who needs to be cuddled, and Roadhog is usually a big, snuggly bear who's happy to provide for his buddy. In canon, Junkrat is a violently insaneexplosives expert who doesn't really do the whole "friendship" thing, and Roadhog is a self-centered nihilist who doesn't even seem to like his partner as anything more than a client.
Hanzo, when he's coupled up with Cassidy. In-game he's a stoic archer who sometimes lashes out at people and tends to see everyone else as beneath him. He was also raised to be a leader of futuristic yakuza and killed his own brother on the orders of the clan's elders. In many fanfics, he's turned into a tsundere, blushy mess who knows nothing about American culture whenever Cassidy's around. It's worth noting that they have never interacted in the story, and the only voicelines they have together are from a non-canon Halloween event where they come off more like Bash Brothers on equal footing. There doesn't seem to be any big difference in their body types (Hanzo's slightly shorter, but he's more muscular than Cassidy). This can have some unfortunate negative connotations, since Cassidy is American, while Hanzo is Japanese.
Poor, poor MC/Minato/Makoto...it's his feminine looks (he's the most feminine looking of P3's heroes, arguably) that turn SEES' leader of quiet strength and sarcasm into a simpering, danger-prone moeblob that rivals Soren's portrayals in Fire Emblem fics. More often than not, the seme is Akihiko, courtesy of him being incapable of talking to girls due to having No Social Skills, and he, normally affable and reliable, will be similarly warped into a domineering gaylord of a sex god.
On the other hand, Akihiko can just as easily become a whiny, desperate little uke in fics where he's paired with his childhood friend Shinjiro. Blame that on his persistent attempts to get Shinji back into SEES, and his reactions to both finding out Shinji had been doing drugs, and when he died. There's actually a pretty even mix of which is the seme and which is the uke, but Shinjiro's usually the more aggressive one in fics.
Yosuke Hanamura of Persona 4 may have some self-worth issues, but they're nothing compared to the whimpering, spineless heap of "OMIGOSH PARTNER SAVE ME!!" that many bad fanfic writers make him out to be. This mostly happens when he is paired with the game's protagonist, though it does crop up in some other ships as well.
In the Pokémon fandom, oddly enough, the Memetic Badass that is Red sometimes gets this when paired with Blue. The almost ubiquitous Self-Fanservice treatment he gets in the fandom doesn't help, though this is mitigated somewhat by his lack of much of an established personality. However, this started to mostly taper out when he and Blue returned in Pokémon Sun and Moon as adults, with Red growing up into a budding Hunk; and instead, Blue became widely seen as the uke instead due to being the bishounen and more emotional of the two, though surprisingly enough he doesn't get it as bad as most other examples due to his established reputation... mostly. Though there is still a good amount of smut and hentai that has Blue as the seme, and it’s also not uncommon for Red (whether it be his child, teen, or adult versions) to be shown as having childish quirks despite his stoicness.
Red's TV show counterpart, Ash Ketchum, is not safe from this either. Considering he's a borderline Keet in canon in contrast to the more hard-headed or stoic characters, it sort of makes sense, though he is still Hot-Blooded, passionate and quite strong in canon as well. In fact, a common joke in the fandom, especially the Japanese one, is pointing out how how this supposed 10 year old is Made of Iron, can leap giant chasms In a Single Bound, lift huge objects, take direct Pokemon attacks, and do other ludicrous physical feats out of sheer determination.
When Blue gets this treatment, his cockiness can be really downplayed to the point it is forgotten, being portrayed more as a straight friend or lovey-dovey love interest to Red than a rival even as their child selves (i.e. before his development in which he humbled out). In stories where his Raticate dies and he’s Woobiefied, he may also get his cockiness downplayed a lot for the sake of making him even more of a Woobie.
In fact, most Bishōnen characters - particularly Steven, Wallace, Morty, Falkner, and Volkner, but also others - are given the uke treatment quite frequently. The first two get it due to the popularity of shipping, and Falkner and Morty get it when paired with each other on when fans interpret Morty's friendship with Eusine as more than just friends.
Professor Sycamore is also a target for this when he's paired with Lysandre. Calem also sometimes gets characterized with an uke-fied personality when paired with Sycamore, Lysandre, or sometimes even Serena or Shauna due to his Bishōnen looks. Granted, he doesn't exactly have a set personality, but not anyone can just charge into the HQ of a psychotic man who basically wants to nuke the Earth...
Unless he is paired with Desmond Miles from Assassin's Creed, where "Desu" gets the treatment while Alex becomes a violently jealous Tsundere no truer to canon than his uke version. Don't expect the female characters or indeed, anything at all from either series to get referred to, even obliquely, if they get in the way of the sex. That includes Alex's body being composed top to toe of an insanely deadly disease.
The gruff, tough, and fearsome gunslinger Arthur Morgan ends up being turned into this, especially whenever he's paired up with John, Charles, or even Dutch.
John, due to being much younger in this game. He's reduced to this whenever he's paired up with Arthur, being delicate and fragile with Arthur as the big protective manly guy and in need of showing their "brotherly love." Despite the fact that John is just as resilient as any of the other characters in the actual game.
Dutch as well, with Hosea.
Leon S. Kennedy of the Resident Evil games gets this treatment after the release of Resident Evil 2 (Remake) where he was still a dorky and naive rookie cop. Some people forget that he undergoes Character Development in the latter part of the game where he progresses into the Deadpan Snarker badass who becomes a government agent since Resident Evil 4. And yet, fanfic writers use the remake version of Leon in stories where he gets molested and raped by Mr. X.
Chris Redfield becomes this whenever he's paired up with Wesker.
Akechi Mitsuhide of Samurai Warriors frequently gets affected by this, especially when paired with Oda Nobunaga. While he is emotionally vulnerable, some writers seem to ignore his courage and determined defense of his beliefs in order to make him a spineless follower and devoted slave of the Demon King.
In the anime series, Yukimura regularly survives discipline from his mentor that creates new land formations, sets people on fire with his fists, fought Honda Tadakatsu to a standstill, and deals with a young lady being preyed on by Eldritch Abominations in a polite but very emphatic way. Most doujinshi and fanfic has him whimpering and crying while Date Masamune takes his innocence. Interestingly, people also often have him crying and whimpering when it's him taking Masamune's innocence (or what remained of it anyway), or at least until they get around to doing the nasty. It's probably the effect of his youthful naivete combined with an emotional and open personality.
As for Motonari...the lesssaidabout his disposition, the better. Anybody attempting to top this guy would do well to watch out for a razor hoop in the ribs, if not a strategically-placed bear trap.
Also Ishida Mitsunari, an extremely disturbed and violent man with a frightening temper that snaps at any given opportunity; the fans make a point of playing him as a Troubled, but CuteTsundere in desperate need of a good lay from his nemesis Ieyasu (whose death is Mitsunari's sole desire), to put him in his place and turn him into a blushing, fluffy kitten.
When it comes to shipping Sonic and Shadow, Sonic is almost always the uke despite the character emphasis on his love for freedom. Compare straight examples from Sonic Remix to deconstructive example He Is My Master.
There's a comic/series of comics on deviantART (pre-"My time here is ogre" edit) that turns Shadow from a quietly brooding badass into a constantly sobbing wreck when speaking withhis friendShrek. The artist insists that they aren't meant to be in a relationship, though.
Luigi. Yes, that Luigi. His canon personality may be soft and gentle and he may be a coward, but plenty of slashers have a nasty habit of removing the spine he does have.
Super Smash Bros. Ultimate: Galeem is multiple times given this treatment by the fanbase, mainly nd because he is only referred to be male in the manual and tutorial, and, while both are equally powerful and dangerous, he is an Angelic Abomination, and Dharkon, the one he's most shipped with (and who's also his archenemy), is directly an Eldritch Abomination.
In Tales of Symphonia fandom, this seems to have become the standard portrayal for Yuan, particularly when paired with Kratos. Never mind that Kratos is canonically submissive to the Big Bad for most of the game — his outfit during that time is even modeled off Japanese bondage gear or that Yuan is a defiantManipulative Bastard with what looks like they might be control issues: Yuan is prettier, so he gets to be uke.
In many Tales of Vesperia yaoi fics, Yuri, who literally has 14 Badass tropes applied to him, has a tendency to get this treatment, especially if paired with Raven or Flynn. Then again, this could be partially due to his appearance, which is even lampshaded in-game.
While not as bad as the previous two in Tales of Zestiria fan works Mikleo does get hit with this despite his canonical refusal to be The Load and is shown to be The Determinator several times. And again it has to do with appearance as the most effeminate looking male character in the game and Sorey considering him to be attractive. However this is more of a case in Japanese fan works as western fan works will either downplay this or avert it entirely.
The Scout's small and thin stature, lack of facial hair and generally childish behavior mean that he's often characterized as a cute, helpless and even innocent teenage boy in fan-work rather than the Hot-Blooded, baseball bat-wielding canonically 24-year old scrapper he is in canon.
Sniper and Spy's bitter, bilious, urine-soaked rivalry is assumed to be a product of Belligerent Sexual Tension.
Demoknight:(to a fallen soldier) "DOMINATED! (sotto voce) But yer a good man and I love you."
Akira of Togainu no Chi. Debatable and may or may not be justified or even exist depending on which route is taken. He starts off as a strong and confident fighter, with no need to rely on anyone else. When he encounters certain sex scenes, he becomes like a typical Uke. This is justified through excessive guilt from the death of Keisuke in Shiki's route.
Despite the Improbably Female Cast, Touhou Project fandom is swimming in this trope, the numerous Badass Adorables afflicted with anything from immobilising stuttering to complete submission and helplessness when faced with the character with whom the writer has decided to pair them. Turning Remilia (an ancient terror of the night with a habit of eating people) into a child with a Precocious Crush, or turning Alice (an antisocial hermit that prefers her dolls over people and possesses enough snark to challenge Marisa) into either a sterotypical Tsundere or a lovesick puppy are the most common, though enough searching reveals examples for nearly every character. Night Sparrow Love is probably the most famous example, and while well-written as an independent work it's difficult to remember that Mystia and Mokou are a con-artist and a borderline-Death Seeker respectively, not the blushing, Cannot Spit It Out sufferers that are depicted.
You would be surprised about how much of this goes on in Touken Ranbu.
In most cases, the hot-blooded and somewhat impulsive Izuminokami Kanesada becomes Horikawa Kunihiro's bratty, needy charge or is a complete submissive in the sheets to either him or other Touken Danshi. It has a lot to do with his relative youth in comparison to many of the other swords (he's technically the youngest character in the game despite having the appearance of an adult), and his less mature personality mutating into a spoiled persona.
Conversely, Horikawa Kunihiro is extraordinarily devoted to Izuminokami, to the point where even the character designer says he has many housewife tendencies, but he's not above tricking him into doing his own work, and he does have a mouth on him. In several adaptations, he's also proved to have strong convictions and sometimes challenges Izuminokami. Not that you'd get that from the fanworks, where he agrees with everything his dear Kane-san says and swoons over him at every turn.
This is generally the case for any type of Saniwa (males especially), but Kashuu Kiyomitsu's affection for them goes beyond what you'd expect. It gets to the point where he follows him like a lost puppy, slavishly desperate for affection.
Yamatonokami has never been able to get over Okita Souji even with his new master, but this is usually exaggerated into a strange obsession with him that goes beyond mere admiration. You'll never hear him saying anything else but "Okita" in some works, or he'll just be angsting for the upteenth time about him.
Yamanbagiri Kunihiro gets a lot of it in fanworks. While he has many hangups about being seen as a copy of a real sword, making him a gloomy person, he still has some sense of pride in himself as seen in his Awakening portrait. He's just downright pitiful in fanon, being not only a pushover but an even bigger sad sack that gets "emotional healing" or gets taken advantage of for his supposed submissiveness.
His real counterpart, Yamanbagiri Chougi also follows this pattern, with his proud and haughty nature and seeming Inferiority Superiority Complex being reinterpreted into a harmless Aggressive Submissive, especially with Nansen Ichimonji and a Kiwame'd Yamanbagiri Kunihiro.
While the World of Warcraft fandom is far from being free of this — usually with some poor blood elf as the victim — the bickering ex-cops Asric and Jadaar seem to dodge the bullet quite neatly. (Then again, this may be due to their personalities: Jadaar—who's a huge, hulking draenei—is usually presumed, by virtue of being the (literally) blue oni, to be the more vulnerable of the two.)
Relationship Sue to compliment Prompto's self-insert status. Or to contrast with how Prompto is often idealized by fandom, Noctis is frequently taken in the opposite direction and turned into a Fetishized Abuser who is abusive and controlling towards Prompto for fetish appeal reasons.
