* Haiji from ''Manga/AiKora'' is a hyperactive, always-cheerful girly LoveFreak. Naturally, [[StupidSexyFlanders he just had to have]] [[ChivalrousPervert Maeda's]] [[{{Fetish}} ideal arse]].
* Akito from ''Manga/{{Air Gear}}''.
* Tendonman from ''{{Franchise/Anpanman}}''. He's the youngest, most traditionally cute-designed, and loudest member of the Donburiman Trio, and was the first Keet of the series, being introduced in the first episode before the other members of the trio.
* North Italy from ''Webcomic/AxisPowersHetalia'' mixes this with TheDitz.
** Poland too, if in a different way (more teasing and playful than cute and hyper), gratuitously mixed with CloudCuckooLander.
** While not necessarily colorful or small, Korea and America are definitely hyperactive and loud.
** And Japan [[http://www.youtube.com/watch?v=QbzlZS4zOVk&feature=related at one point]] thanks to Italy.
** How is Sealand not on this list?
** The Micronations group give us Ladonia, too.
* Isaac Dian from ''LightNovel/{{Baccano}}'' is quite the Keet. And since his partner Miria Harvent is a GenkiGirl, well . . .
** [[EvilIsFunny Ladd Russo]], [[LargeHam Graham Spector]], and [[spoiler:[[CrazyAwesome Claire Stanfield]]]] appear to be evil versions of this trope.
* Toru Nanamine of ''Manga/{{Bakuman}}'' is constantly enthusiastic, even when his one-shot, "Classroom of Truth" doesn't get an award. [[spoiler:It turns out to be an act, as he is actually quite smug and manipulative]].
* Finnian in ''Manga/BlackButler''. Prince Soma, too.
* ''Manga/{{Bleach}}''
** The Sogyo no Kotowari twins from the Unknown Tales arc certainly fit the bill.
** A very early installment had a boy who fit this trope who had ''literally'' been turned into a parakeet.
*** Although, fitting the trope personality-wise is really just implied [[spoiler: until we see him again in the Soul Society]], since his story is probably one of the [[BreakTheCutie truly darkest in the entire series]].
* A somewhat more mild version is Alistair Cornwell alias Stear from ''CandyCandy''. He's very cheerful, energetic and a teenaged AbsentMindedProfessor, but he can also be serious when needed [[spoiler: and ultimately falls victim to a truly tragic death in UsefulNotes/WorldWarI.]]
* Lavi from ''{{D Grayman}}'' is every bit as genki as any GenkiGirl.
* Kanda Yuusuke from ''Manga/ADevilAndHerLoveSong'' tends to act pretty genki at times. He's not small or hyper-active, but seems to be the cheeriest out of the bunch. He holds a bright personality & tends to be overly friendly, which annoys his best friend Meguro sometimes.
* Takeru Takaishi from ''Anime/DigimonAdventure''.
** [[Anime/DigimonAdventure02 V-mon]] is a Genki, well, {{mon}}. [[FridgeBrilliance It's why V-mon's such a great match for Daisuke.]] - while Takeru's busy [[NotHimself not quite]] [[BerserkButton being his usual affable self]] in ''Anime/DigimonAdventure02'', Daisuke takes Takeru's place as the Keet.
** Tagiru Akashi of ''Anime/DigimonXrosWarsTheYoungHuntersLeapingThroughTime''. Dear god, Tagiru. ''Steam blasts out of his nose when he's really excited'', for god's sake.
* Son Goten of ''DragonBallZ''.
* Mizumachi Kengo from ''{{Eyeshield 21}}'' is 203 cm of sheer moxie.
* JJ Adams in ''{{Manga/FAKE}}'', who spends most of his on-panel time gleefully flinging himself at Dee.
* Momiji Sohma from ''FruitsBasket'' is the embodiment of this trope and seems to be in love with Tohru. He grows up at the end and stops being as much of a Keet, though he's still rather genki.
* Manga/GashBell himself.
* Shuichi in ''Manga/{{Gravitation}}'' (see above picture). [[http://static.tvtropes.org/pmwiki/pub/images/ryuichiglomp.jpg Ryuichi]], however, is unarguably the show's biggest Keet. There's [[GeniusDitz another side]] to him, however....
* Micchi of ''KamichamaKarin'' takes this to whole new levels. His interaction with the rest of the main cast comes dangerously close to flirting (both with Karin and Kazune). This is even though he's a year older and OneHeadTaller than either of them.
* Mizuki from ''Manga/KamisamaKiss.'' He's a little older than most examples here but otherwise fits the trope perfectly.
* Yogi from ''Manga/{{Karneval}}'' can be overdramatic and flamboyant one moment, then more serious than his "rival" First Ship's female fighter the next. He's not small and cute, though; just loud and cheery. It annoys the heck outta IneffectualLoner Gareki when his sunshiny personality is directed at him.
* [[WholesomeCrossdresser Kuranosuke]] of ''Manga/{{Kuragehime}}'', while not as small or shrill as your average {{Keet}}, still fits the bill.
* Yuri in ''KyouKaraMaou''. [[CrouchingMoronHiddenBadass Most of the time]].
* Otani from ''LovelyComplex'' is this quite often... awww.
* In ''Manga/MahouSenseiNegima'', a good portion of the male student body falls under this. The final event in the previous year's Mahorafest was a game of ''tag''. Which they aren't repeating this year because there were ''too many injuries''.
** Negi also qualifies when he's able to get away from his TrainingFromHell and responsibilities as a teacher. When he acquires a time machine during the festival arc and realizes he has enough time to do everything, he goes right into adorable-kid mode.
*** His first impulse was to use the time machine to go back and see the dinosaurs.
* Nagisa Shiroi in ''Manga/MermaidMelodyPichiPichiPitch''.
* The aptly-named Genki in ''Anime/MonsterRancher''.
* ''NabariNoOu'': Gau, who is hyperactive, [[HotBlooded passionate]] and regularly loud. Yukimi's nickname for him is "Tenpa-kun", which is derived from the slang term "tenparu" (lit. "about to blow a fuse").
* ''Manga/{{Naruto}}'' in Part I. Not so much in Part II, where he matures. This is lampshaded in the ''Shippuden'' anime when Naruto and Sakura do an {{Omake}} beside their younger selves, and Naruto can't believe how hyper he used to be.
** Akatsuki member Tobi is also hyperactive, especially in the Anime version. [[spoiler: When he reveals himself to be Madara Uchiha, though, he drops the act. Then he turns out to REALLY be Obito, aka the "Naruto" of Kakashi's genin team.]]
** Not to mention Rock Lee and Guy, who are so energetic it even makes Naruto pause at times.
** Of all people, [[spoiler: Senju Hashirama, the First Hokage, has sides of this, especially next to his stoic brother.]]
* Tony Tony Chopper from ''Manga/OnePiece'' to a certain extent.
** Also Luffy. Bright red/orange, prone to yelling, [[GenkiGuy way too much energy...]]
*** And he's extremely short and drawn in a sorta "cute" style with big round eyes. So he's a very straight example...
* A good 25% of the cast of ''Manga/OuranHighSchoolHostClub'', but especially Hunny.
* Oz of ''Manga/PandoraHearts'' at times.
* Mira from ''PapaToKissInTheDark''.
* Tetsunosuke in ''manga/PeacemakerKurogane''.
* Cooro from ''Manga/PlusAnima''.
* Jun/Barry from the ''{{Anime/Pokemon}}'' anime.
** Ash Ketchum himself too, though not as extreme as Barry.
** Hareta from ''PokemonDiamondAndPearlAdventure'' and Gold from ''PokemonGoldenBoys''.
* Eiji Kikumaru from ''{{Prince of Tennis}}'', though he evolves more into a BunnyEarsLawyer as his character [[CharacterDevelopment develops]] through the series. Boys like [[GeniusDitz Jiroh Akutagawa]] and Gakuto Mukahi from Hyoutei Gakuen and [[DarkSkinnedRedHead Kintarou Tooyama from Shitenhouji]] fit more into the archetype.
* Hanagata from ''Anime/SaberMarionetteJ'' is also a CampGay.
* Son Goku (no not that [[Franchise/DragonBall Son Goku]]) from ''Manga/{{Saiyuki}}''. He's this...[[PunctuatedForEmphasis OH. SO. MUCH]]!
** Son Goku is often described as this, especially by fans who have only watched the anime. In the manga, he slowly grows out of it.
* Mikogami from ''{{Sekirei}}'' is a villainous example, and tends to react to anything exciting happening with squealing and comical expressions of joy.
* Ushijima in ''ShikabaneHime'' is another hetero example.
* Mizushiro Hizumi from ''{{Spiral}}'' is "the Devil"... a very, very cheerful and cute one. When he isn't being murderous and/or unbearably angsty, that is - he'll switch between all three moods in a matter of seconds.
* Takuto from ''Anime/StarDriver''. However, [[{{Bishounen}} his gender is]] [[CampStraight definitely in question]].
* In ''VideoGame/TheLegendOfZeldaFourSwords'' [[Manga/TheLegendOfZelda manga]], Red Link is this, much to the annoyance of the [[HotBlooded Blue Link.]]
* Amasawa of ''TheWeathermanIsMyLover''.
* ''Manga/{{Trigun}}'': Vash the Stampede falls into this mode as a part of his ObfuscatingStupidity, but he also seems to take some comfort in the act, especially while enjoying his donuts, which is a sure trigger for it.
* Haru from ''Anime/{{Tsuritama}}''. Cute, eccentric, and least a third of his dialogue is yelled.
* ''VisualNovel/UtaNoPrincesama'' heroine Haruka Nanami's singing idol Hayato is this. Or rather being keet is his image for the fans.
* Nava of ''Manga/WildRock'' as he gets older.
* Kimihiro Watanuki in ''Manga/xxxHOLiC'' is so Keet that eventually Doumeki stops bothering to tell him to quit being so loud and simply covers his ears when Watanuki inevitably gets overexcited. Or annoyed, which happens more often in Doumeki's vicinity.
** He steadily starts growing out of it due to CharacterDevelopment, and then abruptly ceases to be this completely when a certain major character dies.
* Asato Tsuzuki from ''YamiNoMatsuei'' waffles back and forth between being this and TheWoobie.
* ''Anime/YuGiOh'': Yugi, particularly after finding friends.
** [[TheHero Judai]] of ''Anime/YuGiOhGX'' started out as this.
** For ''Anime/YuGiOh5Ds'' Leo/Lua appears to fit this role on occasion.
* Jin from ''Manga/YuYuHakusho''. This is not helped by the fact that he has the same [[Creator/KappeiYamaguchi Japanese voice actor as Ryuichi Sakuma]].
** The concept itself is horribly, ''horribly'' deconstructed by [[spoiler:Kiyoshi Mitarai]], though, since he has the looks of a ''keet'' [[RicaMatsumoto and the voice for it]] [[spoiler: but all it gets him is to be '''horribly''' bullied, which later mskes him lose his faith in people and join Sensui in his quest...]]
