* ''Franchise/SailorMoon'': Haruka Tenoh and Michiru Kaioh. Sailors Uranus and Neptune believe that victory cannot be attained without some horrible angsty [[MartyrWithoutACause sacrifice that only they have the moral strength to make.]] The idea that ThePowerOfLove And Justice could triumph with minimal unpleasantness seems to ''offend'' them on some deep level.\\

In the [[Manga/SailorMoon manga]], it's explained that they basically were ordered by the Queen to live alone in their individual castles at the far reaches of the solar system while the kingdom was destroyed. When they abandoned their posts to try to find the Queen, they accidentally summoned Sailor Saturn and destroyed all of existence. That would pretty well explain their loner natures and pessimistic attitudes (wanting to save their home and all). This is also why [[spoiler:they become a lot more social and friendly after that arc, when they learn that Saturn is not just a force of destruction and decide to raise her.]]
* Seto Kaiba of ''Anime/YuGiOh'', the IneffectualLoner and staunch advocate of independence, self-reliance, and individual strength, which makes a lot of sense when the only way to save the world is by winning a one-on-one match in a child's card game, but no sense when ThePowerOfFriendship rules.\\

These traits were recycled into [[{{Expy}} Edo]] in ''Anime/YuGiOhGX'', who not only [[SlaveToPR strove to be]] an AntiHero, but [[WrongGenreSavvy seemed to think]] he was Franchise/{{Batman}}. This was because he thought he was [[BecauseDestinySaysSo a slave to his fate]]; pity for him that the season's theme was ScrewDestiny.
* Piccolo from ''DragonBall.'' He believes Goku is too soft and kind to be a true warrior. Later villains like Raditz and Vegeta try to replicate this effect, but they [[CerebusSyndrome become less and less out-of-place]] as the story continues.
* While the world(s) in ''TsubasaReservoirChronicle'' aren't exactly clouds and rainbows, {{Ninja}} Kurogane starts out as one of these with little regard for human life and something of a temper, but as he gets closer to his TrueCompanions this gradually fades. In later chapters he's even [[spoiler:sacrificed his arm to save Fay]], indicating that he's fully [[DefrostingIceKing defrosted.]]
* Yue (''Manga/CardcaptorSakura'') is another CLAMP example. Though somewhat hard to pin, his stoicism, bitterness, inability to let go, and the fact that he has no qualms about beating the ever-living daylights out of a ten-year-old girl make him rather a grumpy bear.
** Similarly Syaoran Li, an ArrogantKungFuGuy who constantly gets his mystique destroyed by the cheery and kind spirited treatment of his team mates. Granted his moodiness becomes less visible through that ever recurring LuminescentBlush brought on by his "rival" Sakura's affectionate attitude.
* Zelgadis Graywords of ''TheSlayers'' fits this trope fairly well. While the world he lives in is far from perfect, he is the most cynical member in the group of exuberant nut jobs he travels with. A group which he has tried to part ways with on several occasions, though invariably ends up traveling with anyway.
* [[spoiler:Rossiu]] from ''Anime/TengenToppaGurrenLagann'' becomes one after the TimeSkip. But it's a bit more complex, since he isn't just on the wrong side of the SlidingScaleOfIdealismVersusCynicism. ''Tengen Toppa Gurren Lagann'' is a HotBlooded SuperRobot Anime, but he thinks they live in a [[DarkerAndEdgier gritty]] RealRobot Anime. So his actions are interpreted by some fans of the show as a {{Jerkass}} instead of a cynic.
* Toshiro Hitsugaya from ''Manga/{{Bleach}}''. You know you're this trope when one of your nicknames is "Captain Grumpypants".
* Evangeline of ''MahouSenseiNegima'' counted as this, at least earlier in the series. As of late, the GenreShift into action shows that her attitude may be somewhat justified.
* Fujimoto from ''PonyoOnACliffByTheSea'' is a jaded, cynical human-hater who assumes the worst. He lives in a world that is about as idealistic as possible, and is married to an AnthropomorphicPersonification who distinctly resembles the Blue Fairy in demeanor. HilarityEnsues.
* Kyon from ''LightNovel/HaruhiSuzumiya''. Always negative about everything... when most people would give anything to be in his position.
* ''Manga/{{ARIA}}'' has Aika, who for the largest part doesn't seem to realize that living as an apprentice-undine on Aqua is the next best thing to paradise.
** Which she might have gotten from her teacher, Akira. At least Aika wasn't that way [[CheerfulChild when she was a kid]].
* Meta Knight in ''KirbyOfTheStars''. Fumu calls him out on it, but she eventually gives up.
* Knuckles from ''Anime/SonicX''. Justified in that he's a loner who guards the Master Emerald in Angel Island and has a bad temper which makes it impossible for him to cheer up. Even his [[WithFriendsLikeThese own friends]] [[TheComplainerIsAlwaysWrong doesn't help any matters]].
* ''Manga/KamisamaKiss'' is a RomanticComedy that tends to be light-hearted and very optimistic. The male lead, Tomoe, is a DeadpanSnarker with a pretty cynical attitude.
