Genki Girl



""Your presence itself is like shouting.""

- Yomi, to Tomo (pictured at right), from Azumanga Daioh

"Genki" is Japanese for energetic or enthusiastic. The Genki Girl is a character -- usually a schoolgirl, but not always -- who acts like she's been mainlining Red Bull and crystal meth. She is possessed of an over-abundance of energy, such that she runs everywhere (often with arms waving wildly or outstretched like airplane wings), speaks quickly (sometimes unintelligibly so), and always does everything fast, fast, fast! She's filled with confidence and determination, regardless of whether she's competent or not. Although usually played exclusively for comedy, sometimes the Genki Girl slows down for a serious or introspective moment. But not for long -- she lives her life full-throttle. To sum it up, a good way of telling whether a female character is genki or not is to see if her family and peers are exhausted, astonished or even creeped out by her chronic outbursts of vitality. (A female character is by far the more common version, but this trope is not limited to females)

Despite what you'd think, the Genki Girl is usually not The Ditz. However, there have been a few blends. She is, of course, very often a Motor Mouth or a Nicknamer. If she focuses her powers on getting a boring guy to relish life, she's a Manic Pixie Dream Girl. Less sympathetic portrayals often make her the Jerkass of the group. Alternatively she could be both. Some are even the resident Cloudcuckoolander.

If this is a RPG setting, she's almost always going to be the Fragile Speedster, thus fitting her personality. If she is in a Five-Man Band, she will almost certainly be The Big Guy (and probably an exception to the above if she is).

If a work of fiction gives its characters symbolic flowers that represent their personalities, the Genki Girl will likely get the sunflower while her animal is the cat, though her energy won't necessarily make her go crazy.

Whatever you do, don't give them too much coffee, cola or sugar. And definitely teach them that hard drugs are VERY, VERY bad. This is why she may be preferred with somebody who is practical.

Voice actors sometimes become famous for just being able to keep up the role.

Compare Fist of Enthusiasm and Hot-Blooded. Compare The Pollyanna for endless optimism and cheer rather than energy.

Keet is a related but separate trope.

Contrast Emotionless Girl.

Anime and Manga
"Oh, it's almost 7 o'clock on Saturday! Dinner time!
 * Kurata Sana from Kodomo no Omocha is the archetypical Genki Girl. The Fan Vid Caffeine Ecomium gives some inkling of just how energetic she is; none of the sequences in this video have been sped up.
 * Shampoo, from Ranma One Half.
 * Chi, the energetic kitten in Chi's Sweet Home.
 * Excel from Excel Saga -- Jessica Calvello, her first English voice actress, got just a little too much into the role and wound up straining her vocal cords, which forced her replacement by Larissa Woolcott.
 * Excel Saga's director also gave us Poemi from Puni Puni Poemi. Impossible as it may sound, at times she surpasses even Excel in genki-ness. Puni Puni Poemi seemed to be a deliberate attempt to cram all the insanity of its parent series into two episodes.
 * Haruhi Suzumiya:
 * The title character is a very avalanche of Genki Girlness, who drags everyone nearby along with her. This is expressly stated in the audio drama's main song "First Goodbye", which is, in-canon, written by Haruhi herself (and just as autobiographical as "Lost my Music") with the line "Igai to genki!".
 * Tsuruya-san, a minor character, is somewhat of a Motor Mouth and a cheerful Genki Girl, with emphasis on the 'cheerful'. A natural co-conspirator with Haruhi. (When Haruhi isn't working with Little Sister.)
 * In the 9th/10th novel introduced Yasumi absolutely qualifies. No surprise, considering her true identity:
 * Lime from Saber Marionette J and its sequels.
 * Lirin from Saiyuki.
 * Mink and Pia from Dragon Half.
 * Nabatame Renge from Sweet Ninja Girl Azuki. Also Azuki herself, to a lesser extent.
 * Wakaba Shinohara from Revolutionary Girl Utena.
 * From Azumanga Daioh:
 * Self-described "wildcat high school girl" Tomo (pictured above), when she isn't being a Jerkass and a Ted Baxter. We know she's a Genki Girl because "Genki!" is the first thing she says.
 * Yukari-sensei is what happens when the Genki Girl grows up. Or doesn't.
 * Kaolla Suu from Love Hina.
 * Huang Bu-ling from Tokyo Mew Mew, whose sprinting and flailing is often accompanied by circus tricks like running on top of a ball or breathing fire. As Mew Pudding, most of her fight scenes consist of jumping around and climbing things.
 * To a lesser degree, Hikaru Shidou from Magic Knight Rayearth.
 * Mamoru from Sister Princess.
 * Mikoto from Mai-HiME subverts this trope nicely by simultaneously being a Dark Magical Girl. (Push this type of subversion even further, and you wind up with the Perky Goth.)
 * Radical Edward from Cowboy Bebop.
 * Cisqua when near money in Elemental Gelade.
 * Miki from Marmalade Boy.
 * Minori from Toradora!. Approaches everything with so much energy that she makes the surrounding people look lifeless.
 * Arale Norimaki from Doctor Slump. With a dose of Super-Powered Robot Meter Maids, Cute Bruiser, Strange Girl and definitely Cloudcuckoolander.
 * Bleach:
 * Yachiru Kusajishi is Kenpachi's very own pink puffball of Genkiness.
 * Orihime appears to be one at times, though it seems to be more of a facade than anything. She fits in more genuinely  and a dose of Character Development.
 * Mashiro, which makes a hilarious contrast to Kensei.
 * Senna from the first movie, Memories of Nobody.
 * Nel,.
 * Miaka from Fushigi Yuugi.
 * Manabi from Manabi Straight!.
 * Nozomi from Yes! Pretty Cure 5. With each "Kettei~!", you know she's going to drag the team into some good-hearted but implausible plan, and somehow, her pure energy makes it work. On the other hand, from the following seasons, we have Love Momozono and Erika Kurumi.
 * Tamayo from Kidou Tenshi Angelic Layer.
 * Dita from Vandread fills this role, right down to frequently falling over while running.
 * Nano-Nano Pudding of Galaxy Angel II, who may or may not be an Expy of Bu-ling.
 * In The Ditz variation, Kana in Minami-ke steals the show from her Little Miss Snarker and Onee-Sama sisters.
 * The Tachikomas from Ghost in the Shell: Stand Alone Complex are Genki tanks.
 * Nakuru Akizuki from Cardcaptor Sakura, who is also a Manipulative Bastard. And being a technically genderless spirit being rather than a human girl, though she more or less refers to herself as a girl.
 * Hana-chan from Ojamajo Doremi.
 * Yotsuba from Yotsuba&! is a Genki Girl with training wheels. And to drive the point home, several moments of the story show her with sunflowers.
 * Lulu from Blood Plus is usually upbeat and enthusiastic -- even after.
 * Several characters in Mahou Sensei Negima count; Makie is the most notable example. The entirety of Mahora Academy is described as such, even the boys, by the teachers themselves. It was stated that during a previous School Festival, they arranged an academy-wide game of tag, and afterwards decided not to do that again because there were too many injuries. That year, they were going for a (slightly) more sedate game of Hide-N-Seek, until the Big Bad of that arc provided an army of robots, and they decided to unleash the students on them instead.
 * Winry Rockbell of all incarnations of the Fullmetal Alchemist series. She goes full-on Bishie Sparkle, Squee, and arm-wavy mode whenever she sees something cute or acting cute (Elysia Hughes weeded this mode out of her the first few minutes after she met her), something's caught her interest (mainly anything involving automail, i.e. Rush Valley, or a shopping spree in Central), or a rather vicious (and comic) argument with Ed (again, mainly over automail). The times that she's not Genki mode are when she's realized something tragic or an error in her construction, or when she's concentrating on building a new automail body part.
 * Pixy Misa and Washu in the Pretty Sammy series.
 * Tomoka, Kurumi, and to some extent An (if you don't piss her off) in The Prince of Tennis.
 * Magical Girl Lyrical Nanoha:
 * Reinforce Zwei, in contrast to the original, angst-filled, Reinforce.
 * Nanoha herself is also one, when she's younger. "ATTACK WITH MAXIMUM POWER!!!". Some events and age makes her Older and Wiser.
 * And then we have Subaru (a die-hard fan of Nanoha herself). At least until someone hurts her sister...
 * And Wendi of the Numbers.
 * Lutecia Alpine in ViVid. Yes, really, THAT Emotionless Dark Magical Girl Lutecia from StrikerS. And she is Large Ham now, to boot.
 * Haruna from Kokou Debut (also titled High School Debut) is so genki she's almost Badass Normal. One of her recurring sentences is "let's work hard!" -- cue to high-fiving everyone, running around doing more physical work than the guys and tiring everyone out. Oh yeah, and she can put up a physical fight with guys including potential assaulters. Her over-the-top genki-ness is arguably part of what makes her such an endearing character.
 * In a number of Lighter and Softer Neon Genesis Evangelion adaptations, Rei, of all people, gets this treatment. Seriously.
 * The first Girlfriend of Steel Gaiden Game keeps her in character. The set-in-episode-26's-alternate-universe sequel, however, plays this trope straight.
 * She gets the same treatment in the alternate universe manga Angelic Days (also based on episode 26's AU). So... weird.
 * Torako from Hyakko. She's of the Genki-Ditz blend, considering she makes her debut by leaping out of a window. It's a second story window, but she definitely chooses the quickest way to get from point A to point B.
 * Chrono Crusade:
 * Rosette is what happens when you give a Genki Girl a loaded weapon. It's probably a good idea to run.
 * On the villain's side is also Shader, a Catgirl demon. In the manga she has her serious moments, but in the anime she's 100% Perky Female Minion.
 * Misa from Death Note. Creepiest. Genki Girl. EVER.
 * Renge from Flame of Recca is also a strong contender for that title.
 * Code Geass:
 * Kaguya Sumeragi is like this, as well as The Ojou. She also proves herself to be smarter than you'd guess,.
 * Milly Ashford is another great example, except she is also the Student Council President at the head of an Absurdly Powerful Student Council who is only too happy to find the smallest excuse to start a School Festival. And when that happens, run.
 * Anya Alstreim also becomes one of these after
 * Shirley and Euphie, the respective Love Interests of Lelouch and Suzaku, are also these, and give some much needed lightness to their troubled lives.
 * Ahiru from Princess Tutu -- who is a duck that can magically turn into a girl -- spends most of the show running at top speed, squawking out words so fast it's hard to keep up. She's not even aware that her energy level is unusually high, judging by her confused reaction when another girl from her school fails to keep up with her. This may be because her friends Pique and Lilie are about as energetic as she is, or it may be because she's a duck and doesn't know any better.
 * Both the girls, but especially Mei, in My Neighbor Totoro. Justified in that they're a couple of kids exited about a new house and giant, friendly nature-gods.
 * Sora from Kaleido Star is amazingly energetic. Emphasis on amazingly. Her friends Rosetta Passel and Marion Begnini try to keep up with her, but they still have a way to go.
 * Mileina Vashti from Mobile Suit Gundam 00. Louise Halevy used to be one, but later she's not so genki anymore. And Nena Trinity looked like a Genki Girl, but was actually Cute and Psycho.
 * Hikari from Lamune. Noted by the male lead (her cousin) that she acts much like a kid, despite being a year older than him.
 * Miria Harvent from Baccano!, who even comes with the equally hyperactive boyfriend and partner in crime, Isaac Dian. They seem to have an amplifying effect on each other (at least their seiyuu have this chemistry.) Since they're inseparable for their entire screen time, it's impossible to tell how Genki they are individually.
 * Princess Amelia from Slayers is a truly terrifying mix of this trope and Love Freak. HAMMER OF JUSTICE!!
 * Tenma Tsukamoto from School Rumble is this combined with The Ditz.
 * Himeko from Pani Poni Dash!. Maho!
 * Kendo Team Captain Kirino Chiba from Bamboo Blade is easily the most genki member of her squad.
 * Sakuya from Candy Boy. Particularly with respect to her pursuit of Kanade.
 * Mihoshi Akeno from Sora no Manimani, who's full of energy and passion about two things: astronomy and Saku. She also has a tendency to hug him without warning.
 * Yuki from Saki, though it's actually a bit of a problem for her Mahjong playing since she loses focus after the initial rounds causing her game to drop.
 * Natsumi from Taiho Shichauzo (aka "You're Under Arrest") is genki and loud most of the time.
 * Sakuya from Hayate the Combat Butler, a genki tsundere combo.
 * C-ko Kotobuki from Project A-ko.
 * Nina from Tona Gura is so annoyingly Genki, she nearly causes Emotionless Girl Marie Kagura to punish her, something she never does to anyone outside of her brother Yuuji. In his Chivalrous Pervert mode, Yuuji asks that he be punished in her place. If Marie were to choose this option with Tojo Haya, like as not no one would stop her.
 * Julie from Bakugan.
 * Mana, the Egyptian past life of the Dark Magician Girl from the fifth season of Yu-Gi-Oh!.
 * Bunny from Alice in Sexland pours energy and passion in everything she does. And I do mean everything. That said, she's pretty chaste compared to everyone else in the series.
 * Momoko Kuzuryu in Sumomomo Momomo.
 * Pino from Ergo Proxy, who is really more like a Genki Robot that looks like a girl.
 * Niea from NieA 7 arguably qualifies, even though she mixes her energetic nature with being a total Jerkass.
 * Nikotama Sara from Ai no Shintairiku acts like this to come off as cute.
 * You could consider Akira Kogami from Lucky Star fit into this trope, but you aren't seeing her true personality.
 * Yui would also count. Minami muses that innocent little Yutaka will take on her personality as time goes on, upon meeting her for the first time.
 * Haruhara Haruko from FLCL calms down for maybe thirty seconds an episode, and sometimes not even that much.
 * Ritsu from K-On!, essentially holding the club together with her enthusiasm.
 * Yui of Angel Beats. Justified in that.
 * The titular character of A Little Snow Fairy Sugar, much to Saga's initial annoyance. Saga's cousin Kanon would also qualify.
 * Komugi Nakahara of Nurse Witch Komugi.
 * The titular Cute Ghost Girl from My Lovely Ghost Kana is a strange example. In the back story, she gruesomely took her own life, stabbing herself in the chest many times, and her ghost remained behind, trapped in the apartment building where she died. By the time the real story begins many years later, Kana has forgotten most details of her life, including why she decided to end it. When Unlucky Everydude Daikichi (unable to afford to live anywhere better) moves into the allegedly haunted building, he has a hard time accepting that this cheerful, energetic girl (overjoyed at finally having some company) is actually a ghost.
 * Chika from Ai Yori Aoshi.
 * Hiromi from Aim for The Ace is a gregarious and cheerful schoolgirl, an early version of the trope.
 * Asuka from Future GPX Cyber Formula. Her genki-ness has been toned down in the OVAs, though.
 * Usagi Tsukino of Sailor Moon is an obvious example. Eternally cheerful and loud. Her monologue from the Stars season perfectly expresses it. Here's just the end:

All right!!

With mom's food, and the TV on, my cheerfulness goes up a hundred times! The peace of school, and the peace of my family, and the peace of my sweetheart, and the peace of the universe, I will protect them all together!

Time to eat!

Yes! Energy level at two hundred percent! Cheer bursting at ten billion horsepower! Transform!"


 * Pokémon has a bunch, human and Pokémon alike, though Best Wishes character Iris takes it further (she's this way in the games too).
 * Bianca, your female rival from Black and White is even worse.
 * Ayu in Kanon, contrasting Nayuki, Makoto, Shiori and Mai.
 * Miyako in Hidamari Sketch. While she's prone to sleep in class and can sometimes sleep for 12 hours in one go, once she is awake, she's quite energetic. One episode shows her coming into Yuno's apartment, showing no signs of having awakened two minutes ago; another has Yuno pointing out that she's hyper even in the morning. "That was quick!" is a common phrase applied to her actions, whether she's gobbling down food or making art (usually impromptu). But despite all her teasing, she's a likable person, a good friend... and surprisingly, does well in school!
 * Ran Kotobuki from Super Gals, she runs everywhere and shouts all the time.
 * Ayumi from The World God Only Knows. The first time we see her, she sprinted into the main character, sped through the conversation, and ran off. Into a wall.
 * Road Kamelot from D.Gray-man is a particularly creepy version.
 * Noelle from Tenshi ni Narumon is an extreme version of this.
 * Akiko from Eve no Jikan acts like this when the main characters first meet her. They automatically assumed she was human, only to discover that in public, she is an emotionless Robot Girl. This is a facade, though, so being a Genki Girl really is her natural personality.
 * Hachi from Nana is called a puppy by her roommate for her energy and desire to please.
 * Chizuru Sarashina from Wandering Son is a wacky and eccentric girl who does what she wants to, even going against her schools clothing rules (she wore a bikini instead of the school swimsuit once, sometimes wears a tie instead of a ribbon, and wears the boy's uniform occasionally).
 * Last Order a.k.a. MISAKA #20001 from To Aru Majutsu no Index originally started as an Emotionless Girl like her fellow Misaka clones but when the scientists in charge of Project Radio Noise uploaded a personality program into the Misaka Network, Last Order (the network admin) intercepted the program for herself. Hence the genkiness unlike her Emotionless Girl Radio Noise clones, Dark Magical Girl Misaka Worst and Shorttank Misaka Mikoto.
 * Suruga Kanberu from Bakemonogatari fits this trope well.
 * Tomoko Arikura from Oniisama e..., in contrast to her best friend Nanako.
 * Patty Thompson from Soul Eater maintains a cheerful attitude in any situation. Also she laughs like crazy.
 * Mio Hio and Towa-chan of D.N.Angel.
 * Misaki from Misaki Number One.
 * Axis Powers Hetalia gives us Seychelles and Taiwan. The former has some elements of The Ditz and openly admits to prank calling her former boss England while the latter is a Motor Mouth and the Energetic Younger Sibling to the rest of the Asian countries. Both seem to highlight this element in their character songs, with Seychelles humming her song while the music isn't even playing and Taiwan singing about making problems go "poof".
 * In Street Fighter IIV, we have Chun-Li in this role. Justified, as this is an Alternate Universe where she's much younger than in canon.

Comic Books

 * X-Men:
 * Villain Mojo has a Deadpan Snarker assistant, Majordomo, who in turn has a Genki Girl assistant, Minordomo. Minor can be expected to say "Ohmygosh, OHmygolly..." at least twice per appearance, and will get worked up over something (complete with arm-waving and rapidfire talking -- her version of it goes from sentences to short phrases strung together in the end) more and more until finally having a heart attack. Luckily, she's an artificial human, so Majordomo just has to hit her reset button to get her up and genki again.
 * Early appearances of Kitty Pryde started her out as a Genki Girl, though she actually matured during her run with the team.
 * Her best friend Illyana Rasputin tended towards this when she was in an honestly good mood, which it must be admitted was not all that often after her... growing pains.
 * Megan Gwynn (Pixie) follows both girls in starting this role, then she met Illyana a few times, and she's slowly being broken out of this trope.
 * Harley Quinn, both in the comics and the DCAU.
 * Misfit from Birds of Prey not only embodies this trope, she hangs a huge pink candy-striped lampshade on it.
 * Cyclone from Justice Society of America.
 * Casey from Strangers in Paradise.
 * The Regency Elf in Cerebus the Aardvark.
 * Deconstructed in Young Liars. Sadie acts the way she does because a bullet in her brain destroyed her inhibitions and ability to realize consequences.

Commercials

 * Flo from the Progressive Insurance commercials.

Fan Fic

 * Gabrielle/Takako from the Tamers Forever Series.
 * Alyssa from Keepers of the Elements.
 * The fan fiction Nobody Dies takes this treatment of Rei and gives it a few twists.

Film -- Animated

 * Young Ellie from Disney/Pixar's Up! is definitely one of these. Her wonderful mania for living makes you feel for her all the more when
 * Toy Story:
 * Jessie from Toy Story 2 and 3. What we see of her Show Within a Show character is pure Genki; in her real-life personality, though she displays quite a bit of cynicism and remorse, she still manages to fit this trope.
 * Trixie the Triceratops from 3. Bonnie from the same film seems like she'll grow into one of these as well.
 * Dory from Finding Nemo. Ellen Degeneres, her VA, is a real-life example.
 * Rapunzel from Tangled is pretty lively. Her never having been outside before only makes her more excitable.
 * Charlotte from The Princess and the Frog is a Genki Girl that seems to move entirely too fast for her brain to catch up.
 * The Little Mermaid has Ariel who frustrates her father with how energetic and adventurous she is. Years later when she's grown out of it she ironically describes herself as "a real fish out of water".

Film -- Live Action
"Jordan: I never sleep, I don't know why. I had a roommate and I drove her nuts, I mean really nuts, they had to take her away in an ambulance and everything. But she's okay now, but she had to transfer to an easier school, but I don't know if that had anything to do with being my fault. But listen, if you ever need to talk or you need help studying just let me know, 'cause I'm just a couple doors down from you guys and I never sleep, okay?"
 * Jordan Cochran in Real Genius.


 * Every role Bollywood actress Genelia D'Souza has done. Ever. Even in the non-Bollywood Indian movies. Her most famous Genki Girl role was in the Telugu film "Bommarillu". It was remade into three different languages, and she played the same character in ALL OF THEM.
 * Christine McIntyre's character in The Brideless Groom. She doesn't even have a name, but she leaves one heck of an impression.
 * Sophie in Mamma Mia. Donna and her friends are quite energetic as well, despite being in their fifties.
 * Bahia Ben Mahmoud in the french movie Le Nom des Gens.
 * Toby Walters from Romy and Michele's High School Reunion.
 * Toyo from Ikiru is one of these, with her exuberance breaking Watanabe out of his death-inspired angst.
 * Basanti from Sholay - one of her main character traits was that she doesn't stop talking
 * Eden Brent in Bullets Over Broadway, inspiring the above page quote.
 * Quorra from Tron: Legacy is very much one when not in a life-threatening situation.

Literature

 * The eponymous character of Anne of Green Gables, who has a tendency to spout monologues lasting for more than a page. She stops this in the later books, though.
 * The eponymous heroine of Pippi Longstocking.
 * Prilla from the Disney Fairies series.
 * Suzy Turqoise Blue from Keys to the Kingdom is almost perpetually cheerful.
 * Wendy from John C. Wright's War of the Dreaming.
 * Of all possible people in Warhammer 40000, we are given Felicia Tayber, an Adeptus Mechanius tech-priestess from Death or Glory. With a prehensile tail/mechadendite. Whom Ciaphas Cain may or may not have slept with.
 * The eponymous character of the Junie B. Jones series. So. Much.
 * One of the first eccentricities Winterbourne notices about Daisy Miller is how she's just overflowing with energy and enthusiasm. "It was many years since he had heard a young girl talk so much."
 * The eponymous character of the Ramona Quimby series is rambunctious and noisy and described as "the cheerleader type" by her older sister. Her excitable nature has been known to clash with her friend Howie's stoic demeanor.
 * Andrew Vachss's Burke books have Pepper, although speaking to Burke somehow puts a damper on her energy.
 * Alice Cullen.
 * Kate Weatherhall from The Mysterious Benedict Society.
 * Permanent Rose Casson, and how, from the Casson Family Series. She is described as recklessly boisterous (going so far to cause a traffic jam just to meet a boy her brother knows - and she's only eight!) and when told that her father is going to New York, she about bursts with energetic excitement. Also her older sister Caddy fits to a lesser extent.
 * Beverly Brook in Rivers of London, her enthusiasm frequently leaves protagonist DC Grant exhausted. Especially when she is near a river (well she is an Anthropomorphic Personification of the river by the same name).
 * Squirrelflight from Warrior Cats.
 * Quite a few of Anne Tyler's heroines qualify, especially Pauline in The Amateur Marriage (one of the many reasons why she and her husband Michael are so mismatched). There's also Maggie in Breathing Lessons, Rebecca in Back When We Were Grown-Ups, Pearl and Jenny in Dinner at the Homesick Restaurant, and Muriel in A Patchwork Planet.
 * Effie Trinket from "The Hunger Games".
 * Pauline Stoker from PG Wodehouse's Thank You, Jeeves.

Live Action TV

 * Rachael Ray from her eponymous talk show. She purposely avoids "sob stories" and almost always has a smile on her face. She also works 100-hour weeks and is a rather shrewd businesswoman, and her energy and determination are usually quoted as the source of her success.
 * Giada De Laurentis is a somewhat more sedate Genki Girl, also on Food Network. What probably helps is that, with that largish head and especially large eyes of hers, she even almost looks like a real-life anime girl. Or, to put it visually....
 * Sandra Lee, once again from Food Network... well, fits the "dosed up on caffeine" requirement at least.
 * Ingrid Hoffman is relatively sedate on her English-language show, but watch her in Spanish... it's like Rachael Ray raided Giada's closet.
 * Similarly, Ellen DeGeneres is very energetic.
 * Taylor Townsend of The OC.
 * Scrubs:
 * Elliot Reid was for the most part of the first few seasons highly enthusiastic and quick-talking, tempered with bouts of self doubt (audience: AWWWW!). Her enthusiasm was more of a mask. She was very neurotic on the inside, due to bad childhood experience, overbearing parents, etc. She could be considered a Genki Girl later on, the way she pushes her boyfriends about (sometimes literally).
 * Doctors:
 * Cherry, particularly in her early appearances. When she first started work at the Mill, Michelle got her to put away all the medicine that had been left out, expecting to have to sort it out herself later. Not only did Cherry get it done in record time, while she was at it, she alphabetized all the cabinets to make things easier to find.
 * Chuck from Pushing Daisies.
 * Kimmy Gibbler from Full House.
 * Lorelai from Gilmore Girls. Funnily enough, her daughter Rory is the more grounded one, but Rory has her genki moments as well.
 * Jessie Combs of Myth Busters. Kari slightly less so, but she also delves into this a lot.
 * Abby Scuito on NCIS.
 * Kaylee on Firefly.
 * Claudia Donovan, a hyperactive, always-getting-into trouble techwiz from Warehouse 13.
 * Patty Lane on The Patty Duke Show.
 * Surely Daphne from Heroes must have been written with this trope firmly in mind.
 * Rachel Berry from Glee is the triple threat Genki Girl.
 * Lilly/Lola from Hannah Montana has her moments.
 * Cat Valentine from Victorious.
 * Daisy Wicke from Bones manages to pull it off by being endearing when she isn't being incredibly annoying.
 * Sonny Munroe from Sonny With a Chance.
 * Carly from ICarly, with her loud and spastic nature and her Large Ham tendencies, can be considered this. Their Loony Fan Mandy as well.
 * Smallville's Chloe Sullivan and Lois Lane are like this, and it's become a rather endearing trait in both of them.
 * Dharma from Dharma and Greg is the most energetic flower child you can imagine.
 * Brook from Season 17 of The Amazing Race, who talked nonstop while working a speed bag and jumping rope. Also, Mallory from the same season.
 * Momoyama Lily in the Japanese drama Anna-san no Omame (a.k.a The Best Friend of Beautiful Anna).
 * Valeria Ferrer in Carrusel.
 * This is a common trait on Coronation Street right from the first episode with Linda Chevski(which aired December 9 1960 ) to today's Kylie Platt. Combine this with Really Gets Around and you get one of the shows favourite archetypes the classic "Tart with a Heart".
 * CeCe and Rocky in Shake It Up.
 * Tania Gunadi as this 2nd-grade teacher. "SO MUCH GLITTER!"
 * Emma from Jessie.
 * Kang Jong Hee in Wild Romance is . When she's happy, she's exceedingly happy and takes to biting people.

Professional Wrestling

 * Mickie James, though she fitted the bill more when she was playing her psycho character. Her entrance theme was a Suspiciously Similar Song version of "Hey Mickie" and she would literally bounce all the way to the ring. She calmed the bouncing down after her Heel Face Turn but still fit the trope.
 * AJ Lee when she was on NXT season 3. Overly perky and energetic and she once appropriately had to give a speech about caffeine. "Caffeine will perk you up but I'm some natural dynamite baby".
 * Christy Hemme from the first Diva Search was like this, standing out as the only girl who actually had a lot of personality. Trish Stratus even told her with her winnings she could go buy herself some decaf. Christy responded "it's all natural".
 * Jessica James from the indie circuit and SHIMMER fame is like this as well. It rubbed off on her tag team partner Rachel Summerlynn when they formed Rachel And Jessica's Excellent Tag Team.

Tabletop Games
"48. The elf is restricted to decaf for the rest of the adventure."
 * A Wizards of the Coast free online supplement for Dungeons and Dragons 3.5 describes Mercury Dragons as such.
 * Pathfinder's Curse of the Crimson Throne AP gives us allied NPC Laori Vaus, the disturbingly enthusiastic cleric of a god of Pain and Loss ( Hellraiser ). So genki, she creeps out other members of her church.
 * The book she's introduced in includes the wonderful description of how she made her pilgrimage "Armed only with her indomitable optimism and an appetite for pain."
 * From the list of Things Mr. Welch Is No Longer Allowed to Do In An RPG:

Video Games
"Valygar: For someone who supposedly, you remind me considerably of a chipmunk with a sugar high and a death wish."
 * Midori from Devil Survivor and Airi from Devil Survivor 2.
 * Final Fantasy has a quite a few, in order from the first:
 * Krile Mayer Baldesion of Final Fantasy V is the original example - her little sprite bounces all over the screen when she's happy.
 * This is followed by Relm of Final Fantasy VI - the youngest and by far most innocent of the cast
 * Final Fantasy VII gave us the now infamous Yuffie Kisaragi - a mischievous take on the type.
 * Aerith Gainsborough in her younger incarnation from Crisis Core: Final Fantasy VII. Though she's remarkably sweet about it.
 * Selphie from Final Fantasy VIII, who also has the distinction of being a bit Cute and Psycho.
 * In Final Fantasy IX we get Eiko who is also the game's resident bratty half pint.
 * Rikku in Final Fantasy X. The sad over-tone of Final Fantasy X kept her Genki-ness down a bit (and despite that she's still eccentric and cheerful). In Final Fantasy X 2, Flanderization sets in and she is now Genki Girl incarnate. Although perhaps not to the degree of her 'sisters', Penelo of Final Fantasy XII fills in this spot alongside Vaan in an otherwise very no-nonsense group.
 * Tidus could be an example of a Genki Guy.
 * Vanille from Final Fantasy XIII, on the other hand, is a particularly interesting example.
 * Marle from Chrono Trigger. Although she's not exactly a speedster (though she does know Haste.)
 * Ayla fits this trope almost as well as Marle.
 * Sakura Kasugano from Street Fighter.
 * The King of Fighters series:
 * Kula Diamond in all her hyper-cheery, candy-loving, Face Doodling glory. She's especially notable given her status as an Opposite Sex Clone of the much more serious Kyo Kusanagi, and given that the same experiment that created her led to The Stoic K'.
 * Yuri Sakazaki becomes one of these later on. She's kinda like that in Art of Fighting 2 and definitely in the Capcom vs. SNK games
 * Mignon Beart from KOF Maximum Impact. Also, Athena Asamiya, Mai Shiranui, and Metal Slug crossover Fiolina Germi.
 * Norma Beatty in Tales of Legendia. She goes as far as giving her party members strange nicknames like Senny and Teach.
 * Meru from Legend of Dragoon.
 * Many Suikoden characters are this; sometimes there are many in the same game. For example:
 * Miakis from Suikoden V... initially. Then she gets saddled with an overload of (mostly justified) angst, but eventually reverts to form over the course of the rest of the game.
 * An example from earlier in the series would be Nanami of Suikoden II. Her introduction sequence consists entirely of her shaking her brother around out of giddiness for about 2 solid minutes, culminating when she accidentally sends him hurtling into a cliff wall, leaving a hero-sized imprint in SOLID ROCK.
 * The Fire Emblem series has a lot:
 * Path of Radiance and Radiant Dawn have Mia, who is obsessed with finding her rival (a swordsperson in white) and dueling people at dawn.
 * Tiltyu from Genealogy of the Holy War is a tragic example of how a Genki Girl can eventually break down and cannot be Genki anymore for the rest of her life. Sylvia also counts, and for the second half Fee and Patty (and her replacement Daisy) more then fit the bill.
 * Fire Emblem has Serra (for the most part), Rebecca and Nino, and The Sword of Seals has Thany the pegasus knight and Lalam the dancer.
 * In The Sacred Stones we have Princess Tana as the typical example and Princess L'Arachel as the trope taken to new extremes.
 * Yayoi Takatsuki and Hibiki Ganaha from The Idolm@ster.
 * Yayoi literally refers to herself as 200% genki.
 * Aschen from the Super Robot Wars spinoff Endless Frontier becomes this whenever she lets out her full power. Makes for an... interesting contrast with her usual self. She even goes so far as cheerily shouting out things like "ASCHEN PUNCH!" and "ASCHEN KICK!" Considering that, appearance-wise, she looks more like something out of a robotic Amazon Brigade than a Genki Girl, it makes for an amusing contrast.
 * Izuna from the two merciless games sporting her name certainly qualifies.
 * Though she gets toned down a bit in the later games due to all the torture and all, Imoen, from Baldur's Gate, is rather specifically described by one character:

""Fall, like leaves! In... fall!""
 * Kazooie from Banjo-Kazooie, at least in the first game. In the sequels, she becomes more of a jaded Deadpan Snarker.
 * Marine the Raccoon from Sonic Rush Adventure is a hyperactive Australian slang-spouting Motor Mouth who considers herself to be the star of the adventure, despite being the Tagalong Kid.
 * Arche from Tales of Phantasia starts off very much like this, though mellows considerably after the party . Which, to be honest, is fairly understandable...
 * Ace Attorney:
 * Trucy Wright in Apollo Justice: Ace Attorney.
 * Maya Fey in the Phoenix Wright arc.
 * Kay Faraday in Ace Attorney Investigations.
 * Pearl Fey in the second game. The trip to Kurain Village takes two hours by train. She walked ran all the way.
 * "Hi I'm Daisy!"
 * Starlow/Chippy in Mario & Luigi: Bowser's Inside Story too.
 * From the SSX series:
 * Kaori Nishidake. In a series about death-defying snowboarders, Kaori's excitable nature is explicitly childlike and she just has so much fun out on the snow.
 * Marisol Diez Delgado from Tricky also qualifies.
 * The Dryads' voice-set in Warcraft III portrays this kind of personality for the entire race, along with a touch of The Ditz.


 * Neeshka from Neverwinter Nights 2 has elements of this. Note her kleptomania, habituation to speak very rapidly, and general variance between overwhelmingly excited or deeply anxious.
 * From the Tokimeki Memorial series, Yumi Saotome and Yuko Asahina in 1, Hikari Hinomoto, Miyuki Kotobuki, and Maho Shirayuki in 2, and Itsuki Maeda and Rui Nanakawa in 4. Yumi and Hikari even get the Sunflower as their symbolic flower to drive the genkiness point home.
 * In Mitsumete Knight, one of the Spiritual Successors of the Tokimemo series, there's Carol Palecki, Hanna Shawsky, and Priscilla Dolphan.
 * Eileen from Virtua Fighter.
 * Deconstructed in the GTA Radio from Grand Theft Auto Vice City, where Amy from the VCPR station is a Genki Girl who was put on heavy anti-depressants ever since her family was brutally murdered.
 * In Pokémon Mystery Dungeon Explorers, there's Sunflora. Bianca and Iris in Pokémon Black and White also fit the bill.
 * Jess from Mana Khemia Alchemists of Al Revis.
 * Gretchen Hasselhoff from Backyard Sports, who is both one of the fastest runners and the fastest talker in the series.
 * Touhou Project's Cirno is such a genki girl she gets an entire song in which to display it. "Chirumiru, chirumiru genki, chirumiru!" Marisa also displays levels of genkiness. What else would you expect from a Cute Witch that can fire a giant Wave Motion Gun?
 * Gina of Midnight Club 2 is cheerful, always smiling (or smirking). And Japanese, which explains a lot. (LOL STEREOTYPING)
 * Knights of the Old Republic gives us Mission Vao, a slightly more foulmouthed variant.
 * In a WRPG example, Kasumi Goto from Mass Effect 2 can qualify. She is Japanese too.
 * Flare Pris of Tail Concerto.
 * Hagino apparently has this role assigned to her in Canvas 2 and is required to be cheerful or Hiroki will get upset.
 * In some of the incarnations of Zelda she seems to be full of energy, at least until she gets kidnapped. In The Legend of Zelda the Wind Waker and The Legend of Zelda Twilight Princess, she even helps you fight Ganondorf.
 * The Legend of Zelda Skyward Sword. Apparently, she isn't above dragging her childhood friend around to things she wants to do, doing all the talking whenever she's around (even if Link never talks), and pushing/jumping at him from potentially-lethal flights to make him use the sailcloth/catch her on his Loftwing.
 * Nelie and Orpha in Eien no Aselia. Nelie's twin Shiah looks like she's trying, but she's a little shy.
 * Uriel Chuluun in Rift says "Isn't it exciting?" a lot. Her voice actress sounds cheery even when she's ranting about how her dad is out of touch or stating that "there is something oddly perfect about death." She attempts to give her crush (who's an assassin) a cutesy nickname. She's even got twintails! This is all the more amusing in light of the fact that she's a bahmi (and therefore, a lilac-skinned, tattooed amazon of a Proud Warrior Race Girl) and a Necromancer.
 * Lilica Felchenrow in Arcana Heart is really hyper. Heart Aino, too.
 * Princess Rosella of Daventry - just as fond of adventuring as her dad, impulsive as all get-out, fun-loving and extroverted. Oh, and asked her long-lost brother to prove his identity by showing off a certain birthmark...
 * Megan from Night Trap.
 * The right dialog choices in Persona 3 Portable can turn the female protagonist into one of these, much to the chagrin of the rest of the cast.
 * Kunoichi in Samurai Warriors. Although she mixes an unhealthy amount of creepiness with it, what with her stalking Yukimura and enthusiastically suggesting the most dreadfully violent solutions to any problems that may pop up.
 * Arme and Amy from Grand Chase.
 * Female Tico from Devil Survivor 2.
 * Miley Verisse of Cherry Tree High Comedy Club. Most of her peers think of her as a weirdo because she's passionate about stand-up comedy.
 * Miley Verisse of Cherry Tree High Comedy Club. Most of her peers think of her as a weirdo because she's passionate about stand-up comedy.

Visual Novels

 * Fate/stay night:
 * Fujimura Taiga is an adult Genki Girl.
 * Ilya is too... except she's a genki not-quite-evil girl who likes dismembering Shirou a bit too much.
 * Tsuzuriko/Tojiko in Kara no Shoujo is your stock genki girl... going to school at an academy full of near zombies. You might say she stands out a little.
 * Sachi in Sharin no Kuni. used to be one as well until
 * Arcueid Brunestud in Tsukihime... well, when she's not out killing Dead Apostles and is spending time with Shiki instead, anyway. Kohaku definitely qualifies, too. Especially in Kagetsu Tohya and Melty Blood.
 * Beatrice from Umineko no Naku Koro ni deliberately invokes this trope as per Ronove's suggestion at the start of the fourth arc to cheer up Battler after . However, it turns out that Battler got over that very quickly, and Beatrice just ends up making a complete idiot out of herself.
 * Da Capo II has Yuzu, one of the characters in Nanaka's route, who is as genki as they come, despite being an Ill Girl.
 * From Katawa Shoujo, Emi and Misha, who are rather...interesting variants of the trope. For Emi, In Misha's case,

Webcomics
"Holy crap I feel like I just chugged down an espresso not literally of course that would hurt unless it..."
 * Sapphire from Monsterful: The energetic zombie teenager is way faster and louder than a zombie should be.
 * Kiki from the Web Comic Sluggy Freelance. The one time they feed her Pixie Stix, she makes a ferret-shaped hole in the wall, and circles the Earth three times before the others had even reacted.
 * Robin DeSanto from It's Walky! and Shortpacked! is so genki it qualifies as a superpower. She moves like a bolt of lightning, smells like Skittles, and has less impulse control than your average three-year-old. She once ate a bowl of Cadbury cream eggs; next thing she knew, she'd been elected to Congress.
 * El Goonish Shive:
 * Grace fits this trope sometimes, though she also enjoys sleeping a lot. Sometimes, she combines the two, resulting in the invention of her legendary "Sleepy Little Ninja Stealth Hug"...
 * Catalina Bobcat from the same comic.
 * Add to that.

""Dear Mr. President: I have solved the world's energy needs. All you need to do is put two girls I know on a treadmill.""
 * Jade Harley of Homestuck, even her typing quirk is genki - omitting periods and overusing exclamation points and emoticons. Her Troll counterpart, Feferi, also tends to get overexcited about everything.
 * The hyperactive, lovably eccentric Millie Mudd from Ozy and Millie is a Genki Girl in training.
 * Larxene in the comic Ansem Retort. She's a homicidal version of this, once nuking Disney World because she couldn't get free Funnel Cake.
 * Lisa, and to a lesser extent, Katy-Ann, in Penny and Aggie.

"Aylia: Clearly you've never witnessed [the] homework exploding machine."
 * Missi from Misfile definitely qualifies. While not exactly hyper, she's drastically energetic and upbeat when compared to the rest of the cast. So far nothing, not even being dumped, has been able to make her sad for more than a single panel.
 * Felucca from Earthsong.
 * The always-enthusiastic Molly the Peanut Butter Monster from The Inexplicable Adventures of Bob. It probably helps that she has a super-fast metabolism and can outrun a bear.
 * Freddy from Ghastlys Ghastly Comic is about as much of a Genki Girl as they get. (Well, the genki part, anyway. )
 * Fio from Circumstances of the Revenant Braves is a girl of action and gets restless when sitting around for too long. She even hopes for trouble if it will alleviate her boredom.
 * Girl Genius
 * A comically Ax Crazy version -- Bangladesh DuPree. Her first phrase in the comic is "Ta daa! I am here!" and on the next page she proclaims "Nobody knows more about torture than me!"... just as cheerfully.
 * Agatha when she's on coffee or other stimulation agents.
 * Harmony from Sore Thumbs.
 * Hope From Alone in A Crowd Comic.
 * Asako from Megatokyo is a Genki Girl of Mass Destruction, and her friend Mami knows the arming codes. As Mami says, "Hey, I always reserve the right to use the "Asako option". You should know that by now."
 * Abby from Weregeek.
 * Sugar Shock from School Bites.
 * Daria from A Magical Roommate is a Genki dragon who was introduced to tools and became obsessed. Then she was introduced to modern technology...


 * Randy the Bandicoot from Questionable Content.
 * Serrin from Murphy's Law. As an example, she energetically hugs someone, even if they're an armed stranger.
 * Skull Girl from Super Temps. She has been barred from coffee and sugar twice, her outbursts can create walls of text, and her energy can demolish a multi-story corporate complex in minutes.
 * Nina Delacroix from Eerie Cuties.
 * Pandora from Dangerously Chloe - Chloe's classmate in succubus school, friend and headache. As illustrated on "Karaoke night" bonus page: Chloe sings to the audience, Pandora throws herself into it and enjoys the process. She also generally likes people (even angels), but also likes messing with everyone, just for fun and love of adventure - as enthusiastically as she does everything else.
 * Jennie from The Devil's Panties
 * Mac in Impure Blood Comes running to burble over the car and goes Squee over -- the Abomination.
 * Ivy from Lackadaisy is actually based off of a hyperactive cat that the author knew.
 * Nancy from Zodiac Blues.
 * Myari, from Ears for Elves, is this. Much to the chagrin of Elon who is the other half of their Duo.

Web Original

 * Maria Graham from Survival of the Fittest V4, who's an odd mix of Genki Girl, Cloudcuckoolander, and Stepford Smiler.
 * Toni Chandler, AKA Chaka, from Whateley Universe, is definitely a Genki Girl. She has learned to stay away from caffeine, though.
 * Seth from Dept Heaven Apocrypha, full stop.
 * Rina from Gaia Online, and the Squees.
 * Ginny from A Very Potter Musical, as part of her Manic Pixie Dream Girl persona. Cho comes close as well.
 * Boxxybabee. Nuff said.
 * Gimmick, a Kid Hero Gadgeteer Genius from the Global Guardians PBEM Universe who fights crime in Saint Louis, Missouri.
 * Arella from MSF High Forum. So. So much.
 * Mei from Land Games.
 * Ruby Rose from RWBY shows genki tendencies but also seems more than capable of slowing down and being calm when the moment calls for it.

Western Animation

 * Goo from Foster's Home for Imaginary Friends is a straight-up example. Madame Foster herself sometimes fills this role too, despite the fact that she's an old lady. Coco also shows elements of this at times, with a heavy dose of Cloudcuckoolander and The Unintelligible.
 * Harley Quinn, of Batman the Animated Series. Even moreso in The Batman.
 * Frida Suarez of El Tigre.
 * Ty Lee from Avatar: The Last Airbender, in contrast to her Foil, Emotionless Girl Mai. Also, the latest Avatar, Korra, in contrast to her mentor Tenzin.
 * One of Tenzin's children, Ikki, is this trope personified.
 * Birdgirl from Harvey Birdman, Attorney at Law.
 * Kuki Sanban (Numbuh Three) from Kids Next Door. Her mom's name is even "Genki."
 * Gadget from Chip 'n Dale Rescue Rangers is a combination Genki Girl and Wrench Wench.
 * The eponymous (title) character of The Mighty B!, Bessie Higgenbottom, is an ambitious and optimistic 9 year old Honeybee scout who believes she will become a superhero called The Mighty B if she collects every Honeybee badge.
 * Uniqua from The Backyardigans is one of those. But in one episode, usually-Tsundere Tasha got to be the Genki Girl and show her deredere side.
 * Iris from Ruby Gloom.
 * Izzy from Total Drama Island.
 * Pepper Potts in Iron Man: Armored Adventures is a big time Genki Girl.
 * Hay Lin from WITCH loves life, designing clothes, painting and sending armies of mooks flying with a wave of her arm.
 * Saffi from Jimmy Two-Shoes
 * Kiina's portrayal in Bionicle: The Legend Reborn qualify her as one. It's in stark contrast, with how sour she behaved in the novel that takes place before the movie's events -- however the movie was written first. It was also the only time we saw this side of hers, but it had already stained her image in the fans' minds.
 * Starfire from Teen Titans, partly justified in that her powers manifest from unleashing her emotion. (Although all evidence suggests that anger works better in a fight. In the first episode we learn anything about it, she cheerily explains that her starbolts require "righteous wrath".)
 * Mystique Sonia from Hero 108.
 * Yo from Fanboy and Chum Chum is so genki, she can appear in two places at once.
 * Quinn from Daria lapses into this at times. Stacey, maybe even more so.
 * Moofy, a one-shot character from Invader Zim is both a hilarious and downright scary example of this trope.
 * Dexter's Laboratory: Dee Dee. Oh dear god, Dee Dee.
 * Transformers Prime: Miko, who transferred to an America school to escape a life of piano lessons and ends up in the middle of a war between alien robots, to her absolute delight. Also played by Tania Gunadi, who is good at these.
 * My Little Pony Friendship Is Magic: Pinkie Pie is this merged with Cloudcuckoolander and Taken Up To Eleven.
 * To everyone's surprise, later episodes deconstructed this. Parties are her way of validating herself, and if nopony likes them that must mean nopony likes her.
 * When your life's career is party catering and cheering everypony up, receiving no approval is the worst that could happen.
 * From the same series, the Cutie Mark Crusaders are an entire group of these. They tend to egg each other on.
 * Fluttershy can get like this when animals are involved. Just hearing Rainbow Dash suggest she might want to get a pet is enough to set Fluttershy off.
 * From the original My Little Pony we have Surprise, whom Pinkie is heavily based off in G4. She enjoys pranking people, is very active, and is very loud.
 * June from Ka Blam! started out as one of these, as well as The Ditz. In season two, she's still this trope at times, but much more snarky. In season three, this starts to drop a little bit more as she becomes a sarcastic Jerkass, and by season four, this is gone and she became a slight example of the only sane girl.
 * Lola Bunny from The Looney Tunes Show
 * Cindy, one of the kindergarteners from Recess. Miss Grotke can be a mild example at times.
 * Odd Della Robbia in Code Lyoko has plenty of energy and confidence. And his Lyoko Warrior form is cat-based.

Real Life

 * Boxxy. Internet wars were started over her newfound popularity, with many users (rather hostilely) asking the question "how much genki is too much?"
 * Miley Cyrus. Her little sister Noah is also extremely bubbly, energetic and confident, but she's just 10, so who knows how she turns out.
 * Japanese singer and actress Tomoe Shinohara.
 * Ariana Grande.
 * Comedian Elvira Kurt breathes genki.
 * Hayley Williams of Paramore, so, so much, if the way she answers interviews, tweets, and acts on stage is anything to go by. Not many people would Tweet about how much underwear they're going to buy or make jokes about their own chest during an interview.
 * Bella Thorne and Zendaya Coleman. Bella even moreso, since her Disney Channel intro shows it up.
 * Felicia Day: Her promotional video for Dragon Age: Redemption is marked by energetic smiling, bobbing, and annotating.
 * Amanda Tapping, who never seems to slow down and is always bright, bubbly, enthusiastic, and an all-around goofball.
 * Demi Lovato, when she's in a good mood or with her fans, especially in regards to her fans.

Anime and Manga

 * ''Bleach': Asano Keigo is constantly active and cheerful (or entirely down in the dumps), to the point that he gets on Ichigo's nerves. Though Keigo does have some introspective moments, they are few and far between.
 * Kakeru, the protagonist of Area no Kishi, is a student who channels his love of football into working tirelessly first as manager for his high school football team, and later in the series to overcome obstacles becoming a player himself.
 * Jackie Gudelhian, Johji Ohtomo and Bleed Kaga from Future GPX Cyber Formula are adult versions of the trope. The latter, however, drops off his genki-ness in the ZERO arc when he began to become serious.
 * Raphael from Tenshi ni Narumon, to a lesser degree.
 * Just like Taiwan is the Genki Girl from the Asian Group in Hetalia, her "brother" South Korea can easily be seen as a male version.

Comic Books

 * Most of the Robins have this to some extent, although this was most obvious in Golden Age Robin (which was translated into that of the TV series.)

Literature

 * Harry Potter: Ludo Bagman is energetic and enthusiastic; he is also described as resembling and acting like an overgrown schoolboy.
 * Fregley from Diary of a Wimpy Kid.
 * Jeko from the Col Sec Trilogy is a small, wiry, hyperactive young man who's always trying to rile the resident Tsundere. (On an off note, although it's not anime, it's mentioned at one point that he's Japanese-American.) Enough said.

Newspaper Comics

 * Beetle Bailey's Asian Token Minority character Corporal Yo sometimes has the trait of getting really, really excited about anything he finds interesting, and he likes to run around doing everything as quickly and efficiently as possible.

Video Games

 * The Scout from Team Fortress 2.
 * Kieran from Fire Emblem: Path of Radiance and Radiant Dawn: a Genki Boy who is obsessed with glory. Unfortunately, he and Mia never interact.

Webcomics

 * Order of the Stick's Elan is happy-go-lucky and energetic.
 * Taisei from Sakana, who is extremly cheerful, light-hearted and energetic.

Western Animation

 * Aang from Avatar: The Last Airbender is--when not having to save the world--cheerfully energetic and quite confident. He provides a contrast to the other guys in his group: snarky Sokka and brooding Zuko.
 * Odd Della Robbia in Code Lyoko has plenty of energy and confidence. And his Lyoko Warrior form is cat-based.
 * SpongeBob SquarePants.
 * Peter Griffin from Family Guy is either this or an Adult Child.
