* ''Anime/{{Mobile Suit Gundam SEED Destiny}}'':
** Lacus Clyne suffers this fate from a large part of the non-Japanese fan community. While certain parts of her actions, and more so in the case of her accomplice Kira Yamato, could certainly be a question of perspective, large portions of the community have decided that the [[TechnicalPacifist anti-war]], egalitarian IdolSinger who declined to take control of her country at one point, is, in truth, a [[CuteAndPsycho psychopathic]] ManipulativeBitch who [[WoundedGazelleGambit hires assassins to attempt to kill her to motivate her retired boyfriend return to piloting]] so that she can usurp control of her home country from the current ruler of said country.
*** Similarly, ''DynastyWarriorsGundam 2'' nods to Lacus' Hatedom by having a non-canon storyline where she really ''does'' turn out to be an evil, manipulative queen-bitch who hops into a Gundam and kicks her own boyfriend's ass after he realizes the truth.
** Flay Allster suffers from this ''a lot''. While she isn't exactly innocent in canon (she does go {{Yandere}} for a while), there are ''reasons'' for her SanitySlippage, mostly how she witnessed her father getting blown up. A stunning number of [[AlternateUniverseFic Alternate Universe]] and HighSchoolAU fics, which don't feature Flay's traumatic experience or the existence of Coordinators (thereby removing the FantasticRacism), nonetheless decide to make her a monster. She's invariably the bitchy, spoiled, jealous ''and'' unfaithful girlfriend that Kira is dating at the fic's beginning ''solely'' so that he can break up with her to be with Lacus (or [[HoYay Athrun]]). She always goes out of her way to pick on Lacus, and does her best to make all the characters miserable, [[StupidEvil for absolutely no reason]]. Even the kindest and most forgiving characters will feel nothing but scorn for her, and of course she feels nothing but hatred for them (as a being of pure evil, she can't feel love). Needless to say, Flay's [[CharacterDevelopment canonical]] ''redemption'' will be completely ignored.
** Rey Za Burrel gets hit with this ''and''DracoInLeatherPants depending on which side of the BrokenBase you're on. While the [[DarkMessiah Durandal was right!]] crowd turn him into some sort of hero, haters on the other side are prone to writing him as a monster and a sociopath who cares nothing for Shinn and Luna and shares his [[CloningBlues predecessor's]] OmnicidalManiac philosophy. In reality Rey's a sympathetic AntiVillain who thinks that UtopiaJustifiesTheMeans, cares for Shinn and Luna even as he [[ManipulativeBastard manipulates them]], and rejects Rau Le Creuset's desire to KillAllHumans, seeking instead to [[WellIntentionedExtremist build a better future]]. He's a bad guy, absolutely, but not to the degree that fans make him out to be.
** A parody of such a trope is Kira Yamato himself in one Japanese Gundam flash animation site in which [[http://kenkoudaa.sakura.ne.jp/page080.html Dearka Elsman becomes a hero against the "evil Kira"]]. Normally known as a sincerely good-hearted, peace-loving hero, in this animated short he is altered as one such trope due to the fact he pilots Gundams terribly well.
* MobileSuitGundam:
** Protagonists such as [[Anime/MobileSuitGundam Amuro Ray]] and [[Anime/MobileSuitZetaGundam Kamille Bidan]] have been victims to this trope, too, due to their apparently unlikeable initial personalities, as compared to the DracoInLeatherPants villains Char Aznable and Haman Karn, who, in the eyes of fans, can absolutely can do no wrong.
** Kycilia Zabi and Quess Paraya are also common targets of Char 'pantsers. Because, you know, being a stern leader who takes out a CompleteMonster and a realistic 13 year-old girl [[SarcasmMode are so much more heinous crimes than backstabbing murder and plotting to kill billions of people.]]
** Although not as frequent due to dying off early in the series, Garma Zabi is a victim to this trope by fans that are a little too obsessed with Char. Despite Garma's [[BenevolentBoss concern]] for Earth Federation civilians landing safely and [[GreenAesop refusing to destroy mountains for a military tactic]], fans label him as a spoiled brat because Char calls him this frequently in his thoughts. They also label him as [[AmbitionIsEvil greedy]] for trying to impress his sister Kycilia, despite Garma telling his own fiance Icelina that if push comes to shove [[LadyAndKnight he will choose her over leading this war]]. Leading to his attempt to get his sister's approval to be more of trying to establish a family bond. Char fans also claim Garma was TooDumbToLive due to trusting Char and that [[DisproportionateRetribution he deserved to die so Char could avenge Zeon Deikun]], despite Char [[BitchInSheepsClothing giving no indication that he had more sinister motives]] concerning Garma and the fact that Degwin was never fully proven to have murdered Char's father as well as Sayla, Char's own sister, being appalled by Char's revenge.
* Anime/MobileSuitGundamWing:
** Relena Darlian Peacecraft perhaps gets hit with this the hardest out of any character, [[AmericansHateTingle at least in America]], primarily due to DieForOurShip reasons. The usual fanon portrayal is a shrill, possessive, catty {{Yandere}} homophobic killer bitch, with some stories going so far as to turn her into a female [[LordOfTheRings Sauron]] who needs to be taken out by the heroic (and, of course, gay) Gundam Team. In canon, the character is usually softspoken, understanding, an ActualPacifist, states in her ImageSong that [[IWantMyBelovedToBeHappy she'd let go if Heero found someone else]], and on top of that Duo (the person YaoiFangirls want Heero to get with instead of her) [[ShipperOnDeck actually does his best to set the two of them up together]]. The closest she ever gets to her fanfic portrayal is in perhaps the first two or three episodes where she's kind of snarky and [[WithDueRespect backhandedly polite]] to some condescending Alliance soldiers, but that's about it.
*** Even if you ignore the DieForOurShip, plenty of fans hate Relena because they think she's a useless idiot who detracts from the plot by opposing the war, and is unrealistically naive by believing in peace and pacifism. Never mind that ''Gundam'' is and always has been anti-war, Relena arguably does more to resolve the main plot than the Gundam Pilots and demonstrates a good deal of intelligence and savvy despite only being 15 during the TV show and 16 in TheMovie.
** This also happens to Quatre Raberba Winner. There are fanfictions that portray him as [[KickTheDog kicking puppies for fun]] and [[DomesticAbuse being abusive towards his boyfriend.]] In canon, yes, [[http://www.youtube.com/watch?v=dOaH0tsG3z0 there was the incident with the ZERO System]], but let's not forget: 1) All the other pilots had bad experiences with the system (all except [[TheLancer Duo]] overcame it) 2) Quatre went particularly berserk [[BreakTheCutie because he was already stressed]] [[spoiler: from the death of his father, his sister being seriously injured (to the point of being killed in the manga), and from the argument he had been having with said father over being a Gundam Pilot]], and he was not thinking clearly (especially under [[MindRape ZERO]]) 3) Quatre [[MyGodWhatHaveIDone felt really bad]] [[TheAtoner about what he did.]] Except for that one time, Quatre is [[TheWisePrince a sweetie-pie]]. Why, [[ApologeticAttacker he even apologizes to enemy soldiers for killing them]]!
*** Quatre ''does'' have issues--probably more than Trowa, really, because as the end of the above post indicates he ''believes'' killing is bad even when necessary and yet also believes that it is required and acceptable for him to do it under the circumstances. He's set himself up to be [[RurouniKenshin Hitokiri Battousai]], except he's smart enough at least not to put himself and his machine into the hands of any one faction. He has not made the transition to being a killer as smoothly as he probably needs to; the other idealists among the pilots have solid warrior mentalities to fall back on. But he does not have the kind of issues he's given in such stories.
*** However he's the only one who had that level of issues with the mind-warping ZERO system, probably ''because'' of his inner conflict as well as all the crap he got put through while flying it. Heero and Duo coped better, Trowa is Trowa, and Wu-Fei just used it to go on a VisionQuest. ZERO told him to work with the other pilots. So he did.
* ''Anime/{{Mobile Suit Gundam 00}}'':
** Marina Ismail, another {{Expy}} of Relena Peacecraft, is given similar treatment. Although a devoted total pacifist and a symbol of the fainting good in humans, so many fans tend to hate her for excuses such as being a totally useless, indecisive MarySue. Even her heart-touching song, ''Tomorrow'', does not help.
* ''GundamAGE'':
** Flit Asuno is getting some of this treatment after the timeskip. [[spoiler: While it is true that he TookALevelInJerkass and that his way of dealing with Yurin's death is [[GoodIsNotNice unhealthy]] and sending him JumpingOffTheSlipperySlope, bear in mind that the girl was a possible LoveInterest was brutally murdered in front of his own eyes by Desil, an AxCrazy EnfanteTerrible, and that he's seen many civilians (including his own mom) slaughtered by the Vagan army, so he's got some pretty good reasons to hate them. But tell that to the MisaimedFandom who, after the reveal that the Vagan were HumanAllAlong, seems to have forgotten the atrocities their military pulled. (The non-military people... well, that's something else.)]]
*** [[spoiler: In canon, he kind of doesn't help his case. Even Kio and Asemu get tired of his genocidal attitude after encountering Vagan civilians or meeting sympathetic members of Vagan's military. To Flit for most of the show, he wants to wipe them ''all'' out and become a 'savior'. It took Kio ''bringing Yurin's spirit back from the dead'' to remind him what being an actual savior IS and save the Vagan's Second Moon from self-destruction.]]
