History UngratefulBastard / AnimeAndManga

** At least he stopped trying to kill him in the manga. His opinion of Yugi did eventually change, but that was in Episode 223, and it took seeing Yugi [[spoiler:destroy ALL THREE EGYPTIAN GODS in one move]] for that to happen.

* Louise in ''LightNovel/TheFamiliarOfZero'' might be one of the most exaggerated examples. Saito does/is forced to do so damn much for her after being kidnapped from his home, namely all of her chores, fight all of her battles for her. He even refuses a chance to escape from Halkeginia and go home just to be with Louise. At the end of the second season, he [[spoiler:goes up against an '''enormous army''', and dies]] just to keep Louise safe. All the thanks he gets from her is whipping and beating him until he faints out of sheer agony, and destroying his self-worth to the point where he genuinely believes that he is useless. It's no wonder why many fans [[AbandonShipping prefer to ship Saito with another girl instead]] due to this since they'd treat Saito a '''LOT''' more better compared to Louise. Summed up perfectly by Derflinger:
-->'''Derflinger''': You acted coldly to him again didn't you? And then Partner went away with a bitter face... He says he loves you. Partner gave up on going home and joined the war to follow you, though he doesn't want to get involved in it. Why do you think that is? Because he loves you. Have you ever responded to his feelings, even once? While he devotes himself to you, isn't whipping the only thing you do to him?

* In ''LightNovel/{{Oreimo}}'', Kirino treats her big brother Kyousuke with disdain, even after he helps her open up to people about her unusual hobbies, often humiliating himself in the process. She eventually gets better about it, though.

* In ''LightNovel/SwordArtOnline'', Corbatz, a Lieutenant Colonel in the ALS, demands that Kirito earn over his hard-earned map data, despite Klein saying how difficult it is to map data, saying that he owes it to them after the ALS's efforts to help players. When Kirito complies, Corbatz insincerely thanks Kirito for his cooperation.

Summed up perfectly by Derflinger:

* Swim Swim from ''LightNovel/MagicalGirlRaisingProject'' gets knocked out by Cranberry and is saved by Tama. The moment she wakes up, she [[spoiler:picks up her halberd and slashes Tama's throat. All because she saw her human identity]].

** ''Anime/UFORoboGrendizer'': Duke Fleed and his HumongousMecha is the only thing that stands between the human beings and global genocide. What does he get in exchange? Danbei Makiba bossing him around and [[OverprotectiveDad threatening to kill him if he so much as breathes near his daughter Hikaru]]. Danbei also complains that if Grendizer did not exist, [[TooDumbToLive they could be such good friends with the aliens]].

-->'''Derflinger''': "You acted coldly to him again didn't you? And then Partner went away with a bitter face... He says he loves you.

Have you ever responded to his feelings, even once? While he devotes himself to you, isn't whipping the only thing you do to him?"

** There's also a subversion: As Genma Saotome frequently complains, Ranma Saotome is an "ungrateful son"...except in Ranma's case he's kind of justified, because everything positive Genma did for Ranma was what a father is ''supposed'' to do, while Genma also added a lot of unnecessary negative complications that he then left for Ranma to fix. Really, Genma himself is an example of this trope, ungrateful that Ranma ''does'' constantly clean up after his messes.

* ''Anime/TheHeroicLegendOfArslan'':

* ''Manga/Doraemon'': Shizuka Minamoto combines this trope with the JerkassBall and IdiotBall tropes during one chapter when Nobita decides to pull tricks on her mind after he and Doraemon extract an opal that Shizuka swallowed, making it appear as though she would have to wait for a long time until he and Doraemon escape from inside of her. When Nobita finally reveals the opal that in his hands, instead of being thankful, she goes ballistic. LaserGuidedKarma ensues when Shizuka feeds him the opal herself in her fury.

* ''Anime/{{Pokemon}}''

* ''Manga/RosarioToVampire'': In episode 7, after helping to save Mizore from herself and her [[PowerIncontinence haywire ice clones]], Mizore flat-out tells Tsukune and Inner Moka not to expect her to thank them. In response, Inner Moka lays her out flat and lectures her, telling her to actually try living her life before she starts [[DrivenToSuicide talking about killing herself]]; Mizore takes this to heart.

* Swim Swim from ''LightNovel/MagicalGirlRaisingProject'' gets knocked out by Cranberry and is saved by Tama. The moment she wakes up, she [[spoiler:picks up her halberd and slashes Tama's throat. All because she saw her human identity]].
* Fujimaki Jyuzo from Garouden is on the run from the authorities for savagely killing the man who raped the woman he loved, Saeko. Even though she was the one who told him to do it after he did it she became horrified and called him a monster.
* In ''LightNovel/SwordArtOnline'', Corbatz, a Lieutenant Colonel in the ALS, demands that Kirito earn over his hard-earned map data, despite Klein saying how difficult it is to map data, saying that he owes it to them after the ALS's efforts to help players. When Kirito complies, Corbatz insincerely thanks Kirito for his cooperation.

** First, Saitama destroys a meteor that [[ApocalypseHow would've completely and utterly annihilated at least Z-City and quite possibly a lot more]] but the pieces still hit and cause a lot of destruction. Two of the Tank Top brothers use this and manage to turn the crowd against him. [[WorldOfCardboardSpeech He shuts them down.]]

* In ''Anime/YuGiOhTheDarkSideOfDimensions'', Jonouchi is the only one who stands up for Aigami when some bullies try to pick on him. Despite this, [[spoiler:Aigami later banishes him to another dimension that would slowly kill him, and calls Jonouchi worthless]].

* In ''Manga/BusoRenkin'' , Kazuki risks his life to protect the Hayasaka Twins (the series' IneffectualSympatheticVillain) from Tokiko, who wants to kill them simply because they work for L.X.E. Shusui "thanks" Kazuki by trying to kill him. Kazuki gets better (thanks to Ouka), but even so...

** A villainous subversion in the Dressrosa arc, where Donquixote Doflamingo sees Trafalgar Law as this, as he took Law in as a child and raised him to be his right-hand man, his crew giving him the swordsmanship, martial arts, and marksmanship skills needed to become a OneManArmy, only for Law to turn on him and seek to take his life. However, it's clear to everyone that Law's reasons for betraying Doflamingo are extremely justified. Doflamingo is an AxCrazy maniac with no conscience concerning anyone outside of his own crew, but [[spoiler:his younger brother Rocinante, also called Corazon, was gentle and kindhearted. He was responsible for saving Law's life from an otherwise incurable disease, spending half a year traveling around the world looking for a cure and getting gravely injured in the process. But shortly afterwards, Corazon is killed by Doflamingo for being a {{Mole}} working for the Marines]].

But shortly afterwards, Corazon is killed by Doflamingo for being a ReverseMole working for the Marines]].

** Ash's Charizard used to be a '''major''' example of this. When it was still a Charmander, its [[{{Jerkass}} former trainer]] abandoned it on a rock, leaving it on the brink of death on a rainy night. Ash had saved this Pokémon and took it with him on his journeys. It would eventually evolve into Charmeleon and start disobeying him. Upon evolving into a Charizard, its attitude doesn't improve much and actually costs Ash the Pokémon League Indigo Conference.

** Mjosgard, after just having his life saved by Queen Otohime, tries to shoot her. Then again after he is healed up, all he shouts is his disgust towards having to be with them. And lastly, he voices his anger when Otohime wishes to come with him on his ship. [[spoiler:Later becomes a subversion when Otohime's family visit Mariejois; Mjosgard, who has underwent a HeelFaceTurn thanks to Otohime, greets himself to King Neptune and apologizes for his past behavior.]]

* Louise in ''LightNovel/TheFamiliarOfZero'' might be one of the most exaggerated examples. Saito does/is forced to do so damn much for her after being kidnapped from his home, namely all of her chores, fight all of her battles for her.

All the thanks he gets from her is whipping and beating him until he faints out of sheer agony, and destroying his self-worth to the point where he genuinely believes that he is useless. Summed up perfectly by Derflinger:

* ''Manga/AttackOnTitan'': Bastard might be a bit strong of a word here, but whenever the Military Police Brigade or Garrison are forced to HoldTheLine, they're hoping that the [[TheAce Survey Corps]] will [[TheCavalry reach them in time to save the day]]. Immediately afterwards they and the civilians continue to treat them like crap, calling them weirdos and a waste of resources.
