->''"Mr. Speaker, Members of the House, I shall be brief, as I have rather unfortunately become Prime Minister right in the middle of my exams."''
-->-- '''Pitt the Younger''', ''[[Series/{{Blackadder}} Blackadder The Third]]'' [[note]]This is only a ''slight'' exaggeration -- the actual William Pitt the Younger became Prime Minister at the ripe old age of 24.[[/note]]

The Teen Genius is just that: a genius who happens to be a teenager. This character is responsible for coming up with the magical answer to any given episode's problem, while at the same time being generally angsty and teen-like. May be exposed to discrimination by those that don't know them, because they're JustAKid.

Oddly, the Teen Genius will not normally have any of the odd behavioral quirks of the TVGenius, even if the series [[LongRunners lasts long enough]] to let them mature into an adult.

On a show with an ensemble cast, the teen genius is usually included as a (generally misguided) attempt to appeal to a teen audience. On a show with a teenaged CompetenceZone, this is about the only way for the FiveManBand to include the requisite SmartGuy.

A Teen Genius may sometimes also be BookDumb, despite the apparent contradiction. A female Teen Genius may be a DitzyGenius or GeniusDitz. A younger version is the ChildProdigy.


[[folder:Anime & Manga]]
* Theresa "Tessa" Testarossa, Sagara Sōsuke, and Kaname Chidori from ''LightNovel/FullMetalPanic''. In fact, ''all'' Whispered are Teen Geniuses, as they are all exactly the same age to within three minutes. There's a reason for this.
* Hakuron from ''Manga/HaouAiren'' is a top hitman in the Triads and pretty much the heir to his group... at the very early age of 18/19. His companions are hinted to have been this in the past as well.
* Mizuno Ami/Sailor Mercury from ''Franchise/SailorMoon.'' She's always at the top of the ranking in tests and is rumored by other students to have an IQ of 300. (The ''Theatre/SeraMyu'' musicals treat the latter as fact, not a rumor.)
** Also, Minako Aino/Sailor Venus, despite not being anywhere near as bookish as Ami, has a pretty impressive repertoire and a knack for picking up almost any skill she wants in record time. Not to mention being the tactician and leader of the Senshi.
* The ''Franchise/PrettyCure'' franchise has at least two of these: Yukishiro Honoka from ''Anime/FutariWaPrettyCure'' and Minazuki Karen from ''Anime/YesPrettyCure5''.
* ''Manga/BokuNoHeroAcademia'' has Yaoyorozu Momo as a justified example, her powers allow her to create anything as long as she understands the molecular composition of the things she wants to create, so she has been studying on a very advanced level ever since she was very young. Her intelligence stat is 6/5 on the same level as the the two [[BigGood Big Goods]], All Might and Nedzu, besides the BigBad [[spoiler: All for One]].
* ''All'' the main characters in ''Manga/DeathNote''. Except maybe L, who's in his twenties when the events of the series take place, and Misa, who's a GeniusDitz.
** Light is an especially egregious example--words can't describe his level of thinking.
* ''Manga/{{Naruto}}'' has Shikamaru Nara who has an IQ over 200. He's so smart that everything seems boring to him. Also Itachi Uchiha who had done everything from reaching the very top of his career (Anbu Captain), to joining the most powerful criminal organization as a spy by the time he was only 13 years old. Kakashi Hatake and Minato Namikaze (who would later on become the [[AsskickingEqualsAuthority Fourth Hokage]]) were also teen geniuses when they were young.
** Orochimaru, too. The ninja world has a lot of geniuses, which is to say prodigies. Over 50% of them go violently bananas.
** Sakura Haruno deserves a mention in this category for passing the first Chuunin exam test, which was deliberately designed to be so difficult as to force the participants to cheat, simply by understanding the questions and working out the answers. She was the only test-taker shown to pass without cheating, which is saying something considering that one of said test-takers was the aforementioned Shikamaru.
* ''Anime/CodeGeass'' has [[ChessMaster Lelouch]] [[DarkMessiah Lamperouge]], who planned on toppling a continent-spanning empire even before he gained HypnoticEyes. [[TheScrappy Much maligned]] [[ShrinkingViolet Nina]] [[MeaningfulName Einstein]] also qualifies for inventing and [[spoiler: (almost) building the first nuclear bomb from the contents of a school lab. She later succeeds when provided with some funding.]]
** Lelouch is also a subversion in that at the the start of the series, he is bored to death and extremely pessimistic.
** Mariel from the AlternateContinuity manga ''Suzaku of the Counterattack'' has a [=PhD=] and is described as being only a year older than Suzaku.
%%* Seto Kaiba from ''Anime/YuGiOh''.
%%* Both Miki and Mikage in ''Anime/RevolutionaryGirlUtena''.
* While it is not mentioned very often in the anime, Asuka from ''Anime/NeonGenesisEvangelion'' has already graduated from college at the age of fourteen, making her a candidate for this trope. She's only in high school in Japan to improve her Japanese due to how bad she is at writing/reading it. While Asuka never really uses these skills in the plot itself, they ''are'' quite important for her CharacterDevelopment (c.f. the whole of "Magma Diver"); they don't affect the plot because all the brains in the world won't help you stop the apocalypse.
** In ''Anime/{{Rebuild|OfEvangelion}},'' she's a different kind of genius. Instead of college she joined the military becoming the "Pride of the Euro Airforce" and reaching the rank of Captain by age 14. Which might be a little more useful against apocalypses.
* Akagi Shigeru in ''Manga/{{Akagi}}''.
* Thomas/Touma Norstein in ''Anime/DigimonSavers'', and, to a (much) lesser extent, Koushirou "Izzy" Izumi and Ken Ichijouji in ''Anime/DigimonAdventure02''. (With Koushirou as a former Child Prodigy, even.)
** Due to his age, Ken is more a Child Prodigy than this trope. However, his Dead Older Brother Osamu very probably counts.
* 17-year-old Shin'ichi Kudo and Heiji Hattori in ''Manga/DetectiveConan'' both have vast amounts of knowledge and mental abilities superior to most of the adults around them. [[{{Kuudere}} Shiho Miyano]], on the other hand, led TheSyndicate's lab before she's 18. This trope tends to be somewhat obscured in Shin'ichi and Shiho's cases by the fact that they spends most of the series in ''even younger'' bodies, thus giving them the ''appearance'' of Child Prodigies.
** In the sister series, ''Manga/MagicKaito'', both Kaito Kuroba/Kaitou Kid and Saguru Hakuba also qualify as this.
* Chiyo-chan from ''Manga/AzumangaDaioh'', though a Child Prodigy who starts 10th grade at the age of 10, technically becomes a Teen Genius when she graduates from high school (as valedictorian!) at 13.
* Fuu Hououji from ''Manga/MagicKnightRayearth'' attends a school for the gifted where she studies computer programming. Accordingly, she acts as TheSpock and TheSmartGirl.
* Irina Woods from ''Anime/MaiOtome''. In addition to her normal Otome duties, she also studies engineering and computers, and is very good friends with [[HotScientist Professor Youko]].
* Ryu Amakusa, Megu Minami, and Kyuu [[spoiler: Renjou]] (though he's more of a GeniusDitz) from ''Detective Academy Q''. Their other teammates, Kazuma Narusawa and Kintarou Touyama, are respectively the Child Prodigy and the BadassNormal.
* [[AcePilot Trowa]] [[ColdSniper "No Name"]] [[GadgeteerGenius Barton]] of ''[[Anime/MobileSuitGundamWing Gundam Wing]]''. The other guerrilla Gundam pilots also probably qualify, but he's the only one who [[spoiler: manages to infiltrate Oz]], probably because unlike the other four boys he doesn't have a massive case of ChronicHeroSyndrome to screw things up for him.
** Wu Fei, oddly enough, is apparently their intellectual, followed by Quatre, who's the best military mind among them. Heero has a flair for tactics, although he also acts dumb as a post sometimes. In terms of practical knowledge, they're all extraordinary.
*** Wu Fei was a ''college graduate'' at age 14, as shown in the prequel manga "Episode 0". Also, [[AllThereInTheManual according to the end notes]], had the war not happened and [[ArrangedMarriage his wife]] died to defend their home colony he would have probably become a MadScientist.
** Relena Peacecraft. She's mostly an OrdinaryHighschoolStudent at first, but with some more prodding she [[spoiler: becomes the sponsor of a school ''and'' later... the Queen of the World.]]
* Actually, the Franchise/{{Gundam}} metaseries has several of these. [[Anime/MobileSuitGundam Amuro Ray]] and [[Anime/MobileSuitZetaGundam Kamille Vidan]] were gifted {{Gadgeteer Genius}}es at age 15 and 17, with Kamille even being well-known as an amateur engineer [[spoiler: which is vital when he actually ''designs the Zeta Gundam itself''.]] [[Anime/MobileSuitGundamZZ Judau Ashta]] piloted his mecha at age 14 (a little younger than the Wing boys), and [[Anime/MobileSuitVictoryGundam Usso Ebin]] straddles the line between this and Child Prodigy got his's at age 13 (JustifiedTrope: he was trained by his parents beforehand).
** ''[[Anime/MobileSuitGundamZZ Gundam ZZ]]'''s Glemmy Toto is a villainous example, being a competent (if not spectacular) mobile suit pilot, a superb {{chessmaster}}, capable [[RousingSpeech public speaker]], and a [[ManipulativeBastard political machinator of the first order]] at the ripe old age of [[TeensAreMonsters seventeen]].
*** Haman Kahn is all but stated to have been one, too. At age 16 she was put in hcarge of the Axis Zeon leadership and became the caretaker of little Mineva Lao Zabi. At age 20, she has become TheChessMaster and a foe to fear.
** The most recent examples are from ''[[Anime/MobileSuitGundamAGE Gundam AGE]]'': first-generation!Flit Asuno and his grandson Kio from the third generation. Flit was 14 when he built his Gundam from the blueprints left by his dead mother, Kio began piloting when he was 13 (though in a subversion, his grandpa had been sort-of training him via the videogames that he brought for the kid.)
* In ''Anime/StarshipOperators'', even you're a veteran tactician, you do not mess with Shinon Kouzuki. Trust us, it's a very bad idea fighting her.
* Yue in ''Manga/MahouSenseiNegima'', a [[ThePhilosopher philosopher]] whose strategic abilities have allowed her to even be a threat to magically over-powered foes in the [[MagicalLand magic world]].
%%** Chao and Hakase certainly qualify as well.
* Tony Tony Chopper in ''Manga/OnePiece'' is only 15 at his introduction, yet is an experienced doctor trained by one of the best doctors in the world.
** Nami also qualifies: she is 18 before the timeskip, but she is an insanely good navigator.
* Thanks to a lifetime of TrainingFromHell, [[Manga/RanmaOneHalf Ranma Saotome]] is a Teen Genius in the area of [[MartialArtsAndCrafts Martial Arts]].
** Considering that he spent most of that time travelling and only a few years in school, to be able to be in the same class as his peers is rather impressive.
* ''Manga/{{Bleach}}'':
** Uryuu Ishida is the top academic performer in a 300-strong year group with BunnyEarsLawyer tendencies. When he fought Mayuri, who had spent decades studying Quincies and their powers, Mayuri observed that his abilities were way beyond what he'd expect of a 15 year-old...in fact he used some techniques Mayuri had never even heard of before and one-shotted Mayuri and his bankai ''with a single arrow''. It's been made clear by Uryuu's father, Ryuuken, that Uryuu's power still underdeveloped, meaning that what we saw was only a fraction of his real ability.
** Orihime Inoue is the third best academic performer in Uryuu's year group and a full-blown DitzyGenius. She also has spiritual powers that may directly manipulate space-time, which are so unusual and have so much potential that ''Aizen'' was interested. So unusual, and so much potential, that Aizen kidnapping her was enough for Soul Society to mobilize against him. It's been stated that the limit of her ability is defined by what she believes she can do with it.
** In the ''Everything but the Rain'' flashback arc, Uryuu's father Ryuuken seems to be a Teen Genius as well. Even Aizen admits that Urahara is the smartest person in the series, but Ryuuken, as a mere human teenager, is able to follow Urahara's thought processes well enough to startle him into praising the boy.
* In ''Manga/GetBackers'', most of the major characters are this. Though two extreme examples that have been countlessly {{lampshaded}} are Ban Midou and Makubex. Ban has been called a brilliant genius in fighting (though, according to his witch grandmother, "worthless in everything else") ever since he was a kid, and is currently ''the'' strongest character in the entire series. And Makubex is a 13 year old computer genius that other characters constantly claim is a Teen Genius.
* [[Manga/{{Eyeshield 21}} Hiruma Youichi]], who first learned poker from American soldiers stationed in Japan. After losing the first hand, he figured out the rules without anyone telling him and proceeded to gamble his way to taking all of the soliders' money. By high school, he can count cards in blackjack and earn a ridiculous profit. Has managed to figure out a way to get blackmail material on nearly everyone in the country, and many outside the country.
** Subverted in the World Cup arc when it's made clear that even with all their abilities, most of the talented players in the series still aren't quite at the NFL level yet (though they're still incredibly talented for the high school and possibly college level).
* ''Anime/RakugoTennyoOyui'''s Suzu Koishikawa. She's already got a university-level degree when we see her at the start of the series, and as such her only friend is [[IntergenerationalFriendship a scientist at least twice her age]].
* All members of Spartoi in ''Manga/SoulEater'' (not just Maka's group, but Ox's) most of which are in their mid-teens. Both random Shibusen members and senior staff acknowledge them as 'elite', though this status is certainly helped by the [[SuperpowerLottery number]] [[PhysicalGod of]] [[MorphWeapon unusual]] powers they possess.
* While several characters of ''Manga/HayateTheCombatButler'' are 13 and thus between this trope and Child Prodigy Hinagiku is 16 and thus qualifies for this one, as does Athena ([[InformedAbility supposedly]]).
** Maria is 17 at the time of the series, so she also falls here, though during her time at the school she was a Child Prodigy, [[UpToEleven having graduated at the age of 13, setting a school-wide record that has yet to be borken]].
%%** The school the story takes on thrives on this trope, it's year-end exam is given in German.
%%* Huey Laforet of ''LightNovel/{{Baccano}}'' was a Teen Genius in ''1705''.
* Zera from ''Manga/LitchiHikariClub'' is a certified genius at the age of 13. His sanity may be questioned but he came up with a thinking machine that somehow runs on litchi fruits, his chess skills are superb. More, the prequel shows that in elementary school he constructed a robot all by himself which makes him a ChildGenius too. Dentaku is also very smart, he programmed Litchi. [[spoiler: And against all odds Jaibo may also qualify. For the most part he acts like the psychotic pretty boy but he did manage to frame the original members of the club in such a way so as to completely fool Zera. Unfortunately his pyschotic tendencies boycot his intelligence.]]
* ''Manga/DragonBall'' has a few examples:
** Bulma starts out as one, particularly when it comes to machinery. She built the Dragon Ball Radar at age 15-16, ''without any leads and only with her hands and own knowledge'', basically kicking off the events '''of the whole series'''-and shortly after graduating from college to boot.
** Future Trunks, who while a teen utilized TimeTravel to inform the Z-fighters of the events that led to a CrapsackWorld. (And using a time travel machine that ''Bulma'' herself built [[spoiler: before dying in that BadFuture]], too.)
** Gohan counts too, seeing as he's always been a scholarly type, especially through his teenage years.
** Tighs from ''Manga/JacoTheGalacticPatrolman'' had already graduated from college at 16. Fittingly, the manga's final chapter reveals she's [[spoiler:Bulma's older sister]].
* In ''LightNovel/HaruhiSuzumiya'', Kyon, despite being a BookDumb archetype, solves many problems that involves supernaturalities and practically omnipotent organizations, only with his wit and social skill. Even he doesn't hold a candle to, however, [[spoiler: Itsuki Koizumi, aka the founder and the leader of The Organization]].
* Keima Katsuragi, hero of ''Manga/TheWorldGodOnlyKnows'', who only wants to play his his [[DatingSim gal-games]], and starts the series only putting [[BrilliantButLazy the bare minimum of effort needed into anything else]]. But even then, he typically gets perfect scores on his tests (because he has a deal with his teachers that lets him play games in class) and once he gets dragged into the plot, he proves to be [[GuileHero incredibly competent]].
* Homura Akemi, from ''Anime/PuellaMagiMadokaMagica'' initially appears as this trope, being able to complete all sorts of difficult classwork despite [[NewTransferStudent just transferring]] [[IllGirl from the hospital]]. [[spoiler: This is later revealed to be a result of her GroundhogDayLoop, since she has done all the work in previous timelines]].
* Ciel of ''Manga/BlackButler'' is this trope after he turns thirteen; prior to that, he was a Child Prodigy. His ability to track down the most evil people in London at the behest of the queen while building an extremely successful corporation puts him firmly in the genius category.
* Rei Kiriyama from ''Manga/SangatsuNoLion'' was (and still is, being a high schooler) a teenage prodigy in shogi, becoming a professional player in middle school as only the fifth person to have done so.
%%* ''Manga/ImARoyalTutorInMySistersDress'': Glinda Doyle.
* Mikogami Hayato from ''Manga/{{Sekirei}}'' is revealed to have graduated from an American university before the age of 15, as part of his FriendlessBackground. He's very much a DitzyGenius, but repeatedly outsmarts ManipulativeBastard Higa, a brilliant and ruthless businessman.
* ''Anime/GalileiDonna'': Hozuki Ferrari, thirteen-year-old builder of a collapsible rocket scooter that doubles as an overpowered stun gun, goldfish themed airship, goldfish-themed holographically-projected AI...
* ''Anime/KillLaKill'': In his third year of middle school, [[TheCracker Houka Inumuta]] could hack into the world's tightest security system just as a self-imposed challenge.
* Naru of ''Manga/GhostHunt'' definitely embodies this trope, especially once you learn that [[spoiler: he is actually acclaimed parapsychologist Dr. Oliver Davis, meaning he has a doctorate from Oxford at seventeen.]]
* Suzu of ''Manga/SeitokaiYakuindomo'' is noted to have an IQ of 180, speaks 5 languages and can do 10-digit computations in no time. Shino and Aria share some of these traits, but they're more of {{the Ace}} type.
* ''Manga/YourLieInApril'' is full of middle schooler musical prodigies:
** Fourteen year old Kousei has been considered a ChildProdigy since age five however after his mother's death at age twelve he quit due to [[HeroicBSOD the trauma]]. Thanks to Kaori's encouragement he is getting back into his groove.
** Takeshi and Emi are the same age as Kousei and have been playing for almost ten years. They get overshadowed by him though and that made them both become his UnknownRival.
** Takeshi's thirteen year old younger sister shows prowess at the piano however unlike him she only began playing to get him [[AloofBigBrother to notice her]] and doesn't want to become professional.
** Kaori is quite a skilled violinist however [[spoiler:due to the fact she is SecretlyDying she doesn't get to do it much.]]
* Technically, the entire cast of ''Manga/ShokugekiNoSoma'' qualifies, being world -class chefs in spite of still being in high-school, but even here there are some standouts. To wit:
** Alice Nakiri holds a dozen patents related to molecular gastronomy and has been a fixture in Tootsuki's R&D division for years. She's 16 at the time of writing.
** Eizan Etsuya is 17, and not only the holder of the ninth seat on the [[AbsurdlyPowerfulStudentCouncil Council of Ten Masters]], but also implied to be a significantly better cook than several of his nominal superiors. He also runs a food consulting business on the side, has handled over fivehundred cases in total, and made enough money to cover ''all'' Tootsuki students' (that's about 1000 in high-school and an unknown number in middle school) tuition fees in his freshman year.
** Viciously deconstructed by Jouichiro Saiba [[spoiler: He became very good early on, and was pressured by his surroundings to reach even greater heights, but no-one acknowledged the hard work that made him who he was, and chalked all his successes up to 'genius'. The joy he had experienced evaporated in the face of pressure, and [[CordonBleughChef experimental cooking]] which he used to rediscover the joy and bring the expectations of his surroundings down a little didn't fill the hole. In the end, he had to leave both Tootsuki and cooking behind to not suffer a complete nervous breakdown.]]
* Most of ''Manga/Classi9'''s cast consists of teen geniuses: Class S- is made of [[BunnyEarsLawyer quirky]] but extremely talented musicians based on some of the most prominent classical European composers.
* A good chunk of the cast of ''Manga/KaguyaSamaLoveIsWar'' are geniuses, with [[StudentCouncilPresident Shirogane]], [[TheOjou Kaguya]], and [[RecurringExtra Maki]] as the top three ranked second year students ([[NiceGirl Kashiwagi]] used to be fourth, but she fell to seventh due to spending most of her study time helping her boyfriend). [[MoralGuardians Miko]] is ranked first among the freshmen, and [[BrilliantButLazy Ishigami]] is GoodWithNumbers.

%%* Dilton Doily from ''Franchise/ArchieComics''.
* Brainiac 5 from ''ComicBook/{{Legion of Super-Heroes}}''. All Coluans are smarter than humans, and his family moreso than everyone else.
** The first Invisible Kid was said to be a genius by human standards as well and created his own invisibility serum. In the Reboot Legion it was established that, while Brainy was smarter, Invisible Kid combined his smarts with imagination - it was Brainiac 5 who created an anti-gravity metal, but it was Invisible Kid who used it to create flight rings.
* ComicBook/KittyPryde of the ''Comicbook/XMen'' was introduced as this. So was her friend Doug Ramsey of the ComicBook/NewMutants -- [[WhatKindOfLamePowerIsHeartAnyway his powers had to do with languages]] and he was unfortunately [[BlessedWithSuck incapable of contributing anything else to the team]].
* There's a ludicrous number of teen geniuses in Marvel. [[ComicBook/TheIncredibleHercules Amadeus Cho]] is probably the smartest, but there's also David Alleyne/Prodigy of the Young X-Men, Victor Mancha of the Comicbook/{{Runaways}} and Jonas/Vision II and Kate Bishop/Hawkeye II of the ComicBook/YoungAvengers. And that's even without including the ghost of Alex Wilder (''Runaways'' again) and the currently MIA Kristoff Vernard von Doom (the adopted son of Doctor Doom, and while he's aided by having the majority of Doom's knowledge downloaded into him, clearly Doom would never think of choosing somebody without brains of their own as his heir).
* [[ComicBook/FantasticFour Mr. Fantastic]], who not only is the biggest nerd in the world ''and'' a RubberMan BadassBookworm, but was attending university at age 14 ''and'' by the time he turned 20 had several science degrees under his belt.
** Meanwhile, Doctor Doom's first origin story shows he'd been a scientific wunderkind in his teen years, developing convincingly life-like robots, and freeze grenades, among other things while travelling around rural Latveria.
* Hiro Okamura from Franchise/TheDCU. He builds a composite robot to save the world from a kryptonite meteor, and Franchise/{{Batman}} states that Hiro's smarter than him.
** This is made even more evident in the movie ''Franchise/{{Superman}} / Franchise/{{Batman}}: Public Enemies.''
* Peter Parker, a/k/a ''Franchise/SpiderMan''. Although, after 40 years and with all his smarts, Peter's still taking pictures for the Daily Bugle.
** Then he stopped doing that and went to work for Horizon Labs, putting that brain of his to work.
** [[ComicBook/DoctorOctopus Otto Octavius]] earned his doctorate at age 16.
* [[ComicBook/RobinSeries Tim Drake]], the third Robin and current Red Robin, is regarded as the smartest of Batman's proteges, and Batman had stated that Tim could potentially be smarter than himself. Tim had already figured out the [[SecretIdentity secret identities]] of Batman and the first Robin when he was ''nine'', [[AwesomenessByAnalysis by watching a video of them fighting and recognizing Robin's gymnastic moves as those of former circus star Dick Grayson]].
* Tekno in ''ComicBook/SonicTheComic'' seems to be this, but due to the VagueAge principal of the comics it's unknown if she was a teenager or if she's currently one.
* Jack B. Quick, youthful InsufferableGenius of the short-lived ''ComicBook/TomorrowStories'', published by the equally short-lived Creator/AmericasBestComics by the incomparable Creator/AlanMoore. A poor man's tongue-in-cheek Literature/TomSwift.
* [[ComicBook/IronMan Tony Stark]]: While all comic stories featuring him show him as an adult, it's said he graduated from MIT at the age of 17.
* ComicBook/LexLuthor was just as much a genius as a teen as he became as an adult. He even tried to enter his high-school's science fair with a toaster powered by nuclear fission!
* ''ComicBook/ZipiYZape'': Zipi and Zape actually fit here. Despite having bad marks at school, they are both depicted as extremely intelligent, and always being able to figure out an answer to any problem.
* Emily the Strange is a 13 year old goth girl who can build bizarre contraptions, such as a "time-out machine" or a computer thing called the "Oddisee".
* The [[{{Creator/DarkhorseComics}} Dark Horse]] series, Pariah, is about a bunch of these who have been left to fend for themselves on a derelict [[{{Main/SpaceStation}} space station]] by a fearful government back home.
* By Season 10 of ''Series/BuffyTheVampireSlayer'', Giles has been turned into this; the result of a resurrection spell that went partially wrong and brought him back in the body of a 12-year-old.

[[folder:Fan Works]]
* ''FanFic/YinAndYangSeries'': Romama, who is already ranked Major at his age (about 13), for his fighting prowess.
** Kirere can also qualify, at approximately age 11, since she's building invasion weapons for her platoon already.

[[folder:Films -- Animated]]
* ''WesternAnimation/MyLittlePonyEquestriaGirls''
** Sunset Shimmer is described as a genius in the tie-in novels. She's good at [[TheAce just about everything she tries]], including creating a cell phone app that lets someone digitally see what they would look like in a set of clothes, and is at or near the top of all of her classes. Also, she's pretty much the human world's only real authority on magic, having to help guide her friends on its power once it starts showing up.
** When she appears, Twilight Sparkle's human-world counterpart is shown to be [[AlwaysSomeoneBetter even smarter than Sunset]]. One of the music video shorts shows her using [[MadScientist mad science]] to create a robot pal for her dog, Spike. And when she and Sunset Shimmer competed in a math competition in ''WesternAnimation/MyLittlePonyEquestriaGirlsFriendshipGames'', both were solving a complicated math problem at an equal pace, but in the end Sunset only barely loses by being just a few digits off, while Twilight gets the correct answer. The difference is that while Sunset is [[JackOfAllTrades good at everything but the best at nothing]], Twilight is mentally peerless, but is [[ShrinkingViolet incredibly shy]] and TheMillstone in any kind of physical activity.
* Hiccup in ''WesternAnimation/HowToTrainYourDragon''. He's also good at building things and likes learning about dragons.
* Hiro Hamada from ''Disney/BigHero6'', who had already graduated from high school at age 13 at the start of the movie and was being persuaded to attend college by his older brother Tadashi, who technically also counts as a teen genius as well.

[[folder:Films -- Live-Action]]
* All the main characters in ''Film/RealGenius'' apply, even though half of them are over 19. The main character is only 15, and Jordan (at 19) is also a GeniusDitz.
* Lex and Tim Murphy in ''Franchise/JurassicPark'' combined were the Teen Genius. She was the computers; he was the dinosaurs.
* Chekov in the 2009 ''Film/StarTrek'' movie.
* ''Film/DonnieDarko''. His test scores were "intimidating".
* Josh from ''Film/AndYouThoughtYourParentsWereWeird''.
* The ''Film/IronMan'' movie confirms that Tony Stark was already a genius back when he was a teenager; he graduated top of his class from MIT with a prize-winning invention when he was 17 and cracked the Pentagon's firewall on a dare at the same age.
* Shuri from ''Film/BlackPanther'' is 16 and already the head of the Wakandan Design Group, in addition to having several inventions under her belt — including T'Challa's "Sneakers" and the usage of vibranium as an energy source.
* Peter Parker from ''Film/SpiderManHomecoming'' is 15 and, without any previous exposure to a lab or engineering, managed to make unprecedented synthetic webs (and web-shooters) with supplies he scrounged from the dumpster and his high school chemistry lab. He also seems to possess an aptitude for physics, and mentioned designing, building, and programming computers with scraps from the garbage in his spare time.
* Vitya Sereda in the Soviet film ''Film/MoscowCassiopeia'', who came up with a new way to store antimatter and a working plan for a rocket at the age of 14.

* ''Literature/HarryPotter'':
** Hermione Granger.
** Though never directly shown, Dumbledore, Voldemort, Grindelwald, [=McGonagall=], Lily Potter (née Evans), Severus Snape, and the Marauders (who became Animagi by their fifth year at Hogwarts!) are all implied to have been Teen Geniuses in their own times.
** Fred and George Weasley may have earned [[BookDumb three OWLs each]], but they are capable of advanced magic and become successful businessmen after dropping out of Hogwarts... at 18 years old. While Percy is a pompous Jerkass, he had to have been pretty smart to have become Junior Assistant to the Minister of Magic... also at 18 years old. Though that whole [[RunningGag 18 years old]] thing may be justified, as we never read even a single mention in the series about any [[OffscreenMomentOfAwesome Wizarding Colleges]].
* Astrid Ellison of the ''Literature/{{GONE}}'' series) Has a IQ of over 150, can quote ''whole passages'' of classical literature (Including Dickins, Shakespeare, Hemingway, Bronte) and [[WordOfDante learnt to read aged two]]...Did we mention she's only 14 when first introduced? She's more a literary and [[BadassBookworm book-based genius]] than a scientific or mathematical one, though.
** While we're on that series, Computer Jack is just twelve and he's handling all of the FAYZ's tech issues.
* All children of Athena in ''Literature/PercyJacksonAndTheOlympians'' , although most notably [[TheSmartGuy Annabeth Chase]] (who starts off a child prodigy but evolves into a teen genius in book 2). She is a ''archaeological'' based genius, who knows of every great building in the world along with its exact measurements, perimeter, area, when and by who it was built, and its historical significance. She also possesses an adept talent for general knowledge, being able to answer every question the Sphinx asks her in book 4 and complaining that it was too easy, while the rest of the rather intelligent group couldn't answer one question.
** She is such an insanely smart architect that the literal '''GODS''' made her Olympus's official architect. She builds palaces for divine beings. That's how badass smart she is.
* ''Literature/ArtemisFowl''. Technically not a teen in the first book, since he was twelve then, though he gets older later on. And he is smart, to say in the least.
* Lilly Moscovitz from ''Literature/ThePrincessDiaries''. She has an IQ of 170.
* Frank Hardy from ''Literature/TheHardyBoys''.
* Practically ''every single character'' in the ''Literature/EndersGame'' series of novels. Spooky geniuses.
** Definitely justified, because that's what the Battleschool program was specifically looking for.
* In the ''Literature/GarrettPI'' series, Kip Prose is a teen inventor, with a head full of ideas for things that hadn't yet been developed in his world (pencils, tricycles). Subverted in that he got his first batch of ideas from [[strike: aliens]] sky elves, rather than dreaming them up from scratch.
* Creator/JamesHSchmitz's Literature/TelzeyAmberdon starts out as Star Honor student at the planet's top law school at age 15, ''before'' she is TouchedByVorlons. Then again, the student body of Pehanron College seemingly isn't much older than Telzey is; her roommate Gonwil is 19, but she's in her last year, while Telzey still has several years to go. It's either a prep academy for nothing but Teen Geniuses, or the Hub's education system is a tad accelerated. Telzey is still the top student in her year, that's true.
* In ''Literature/TheBabysittersClub'', [[AsianAirhead Claudia's]] older sister Janine has an IQ of ''196'' and takes college classes while in high school.
* In ''[[Literature/TheMazeRunner The Maze Runner Trilogy]]'', while all of the Gladers were selected for the Maze trials partially due to their high intellect, Thomas and Teresa take the cake [[spoiler:due to being the ones who quite literally designed the Maze itself]]. It’s somewhat of an InformedAbility, in that throughout the books the Gladers act like teenagers of fairly normal intellect while making decisions and attempting tasks.
* ''Literature/TomSwift''.
* Frank Reade, Jr.
* DimeNovel character Johnny Brainerd and The Steam Man of the Prairies. Most likely the UrExample, predating even FrankReade and Literature/TomSwift, circa 1868. Earliest example of an "Edisonade," a kind of proto- Steampunk.
* Aaron Stampler from ''Literature/PrimalFear'' by William Diehl.
* All Creator/EnidBlyton's BoardingSchool novels seem to have a handful of these characters. ''Literature/StClares'' has Felicity's musical genius and the almost [[MarySue Sue-ish]] Lucy Oriell who is perfect at everything, ''especially'' art. ''Literature/MaloryTowers'' has even more - even in-story Irene's talent for maths and music is called "genius", Mavis has the voice of an opera singer at the age of fourteen or fifteen, and no-one can match Belinda's drawing skills.
* Literature/{{Psmith}} starts out as one of these combined with HighSchoolHustler.
* Caitlin Decter in Robert J. Sawyer's Literature/WWWTrilogy.
* Cadell in the ''Literature/EvilGeniusTrilogy'' grows from Child Prodigy to EvilGenius in the first few chapters of the first book. Obviously, most of the other students in the [[AcademyOfEvil Axis Institute]] and the members of Genius Squad count.
* ''Literature/TheGallagherGirls'' series has [[DitzyGenius Elizabeth Sutton]] who is 13-18 throughout the course of the series, and was so smart she joined ''MENSA'' by the age of 8 and was published in ''Scientific American'' aged only 9.
** MENSA really will let you [[https://www.mensaforkids.org/ join as a child or teen]]. And in general [[https://www.theatlantic.com/national/archive/2013/04/toddler-mensa-member-are-more-common-than-you-think/315923/ MENSA is very welcoming to young people]].
* Creator/SimonaAhrnstedt has at least two examples.
** Beatrice Löwenström in "Överenskommelser" is still a teenager at the start of the story, and yep, she's very intelligent. Kind of justified as she was the daughter of a University professor, who had given her a good education and encouraged her to be intelligent.
** Illiana Henriksdotter in "Betvingade" is still a teenager as well, and a brilliant medicine woman.
* The title character in ''Franchise/EmilyTheStrange''. She is called out for it in ''Literature/EmilyTheStrangeStrangerAndStranger'' when she outsmarts Venus Fang Fang's backyard alarm system.
* Gaia Moore of the ''Literature/{{Fearless}}'' novels, in addition to being an ActionGirl, has an IQ far outstripping that of any of her classmates, can speak multiple languages, and is able to perform reasonably sophisticated decryption. She'd almost qualify as a MarySue if all of this wasn't balanced out by her life sucking on a number of levels.
* Like many other Creator/JohnGreen characters, Hazel and Augustus from ''Literature/TheFaultInOurStars'' are insanely philosophical and verbally articulate for their age. Notably, though, [[DelusionsOfEloquence they do get a lot of things wrong]]. For example, Hazel misunderstands relativity, statistics, and the concept of infinity, and Gus says "soliloquy" when he means "monologue". [[WordOfGod According to the author]], this was on purpose, to show that even though they're very intelligent, they're still young and inexperienced.
* Many of ''Literature/TanteiTeamKZJikenNote'''s male cast comes from a team of {{Academic Athlete}}s that requires, at a minimum, a national 97th percentile in academic performance, which potentially put all of them into this trope. However, [[GoodWithNumbers Uesugi]] and [[EncyclopaedicKnowledge Kozuka]] plays this trope the straightest.
* Karma of ''Literature/TheGirlFromTheMiraclesDistrict'' is a teenaged girl who's also a brilliant hacker capable of making a comfortable living - and even buying an old movie theatre to live in - with her skills.
* Camilo of ''Literature/ConElDiabloEnLosTalones'' is the top student in his high school by a long shot. Protagonist/narrator Desi talks about him this way:
-->The teachers, tired of getting shown up when it was proven on several occasions that he knew twice as much as them about anything, gave him an A+ as soon as they saw his name on the exam. They didn't even bother analyzing them. Why waste time?
* Susan Sto Helit in ''Discworld/SoulMusic'' is something of an InsufferableGenius - a near-StrawVulcan who knows she knows more than all her classmates and most of her teachers, but ''doesn't'' know is why pointing this out [[LonelyRichKid doesn't make her popular]]. (It doesn't even make her top of the class; she's doing badly at Literature because she doesn't see the point of poetry and fiction.) In later books she's both grown up and learned that believing in logic on the Discworld is fine as long as you don't expect reality to co-operate.

[[folder:Live Action TV]]
* Lizze Sutton from ''Series/LincolnHeights''
* Doogie Howser from ''Series/DoogieHowserMD''. The show is unusual in that it completely centers on a Teen Genius.
* Bryce Lynch from ''Series/MaxHeadroom''.
** The original TV movie version of Bryce was completely unlikable and a bona fide villain but the version from the TV version is one of the most likeable examples of this trope, in large part because he was depicted as a normal teenage boy who happened to be a genius. The TV series Bryce could be a DitzyGenius at times and had much the same sense of humour as any 15-year-old boy. He could just do cooler stuff.
* Willow from ''Series/BuffyTheVampireSlayer''.
** Later on, Dawn, who is established as a good student and decent chess player in her first appearance, a couple of seasons later translating mystical texts from Ukrainian and ancient Sumerian.
* Mac from ''Series/VeronicaMars''.
** Quite possibly Veronica herself, as well.
** Cassidy "Beaver" Casablancas.
* Malcolm from ''Series/MalcolmInTheMiddle'', as well as his brother, Dewey, and his classmates Lloyd, Dabney, and Stevie.
* Lucas Wolenczak from ''Series/SeaQuestDSV''. A rather successful example of the trope; where the character and the actor became a [[TeenIdol hit]], from an otherwise flop show.
* Wesley Crusher from ''Series/StarTrekTheNextGeneration'', an example of what can [[CreatorsPet go wrong]] with this trope.
* Doctor Zee from ''Series/{{Galactica 1980}}'' was not only a Teen Genius, he was weird and fey enough to qualify as an OracularUrchin.
* 'Series/DoctorWho'' has companions Zoë and Adric, and one-off character Luke Rattigan.
* Luke Smith from ''Series/TheSarahJaneAdventures'' appears to be this, subverted in that he was [[ArtificialHuman created with a body]] [[YoungerThanTheyLook on the onset of puberty]].
* A less common example would be Quinn Mallory from ''Series/{{Sliders}}'', who, although not a teen at the time of the series, falls under the category by virtue of being young, brilliant, and angsty.
* River Tam from ''Series/{{Firefly}}'', who is seventeen years old and makes her brother Simon (who was in the top three percent of his class at an elite medical school) look like an "idiot child" by comparison -- or so Simon says. Also, she can read minds. The angst factor comes from the fact that she's [[CloudCuckoolander crazy]] as a result of [[MindRape cruel medical experimentation]] done to her at [[SchoolForScheming the Academy.]]
* Billy Cranston from the original ''Series/MightyMorphinPowerRangers'' team.
** Rose from ''Series/PowerRangersOperationOverdrive'' was this in the backstory, but by 18 years old, she was already out of Harvard and working in a university in London. If she's 18, she's technically still a teenager.
** Also Dr. K in ''Series/PowerRangersRPM''. She starts with "abducted into government think tank by age 6" and goes from there (she's about 18 at the time of the series).
* Alex P. Keaton from ''Series/FamilyTies''.
* Steve Urkel of ''Series/FamilyMatters''.
* ''Series/{{Lost}}'' contains a former Teen Genius: Daniel Faraday was a ''professor at Oxford'' and doing time travel experiments by the time he was 19 and he had already graduated sometime in his early to mid teens-explicitly said to be the youngest ever graduate. Then he did said experiments ''on his own girlfriend'', something that went so badly that Oxford ''wiped any record of him ever having taught there''-and by the time we meet him, he's 27 and has memory problems so bad he needs a constant caretaker.
* ''Series/{{NCIS}}'' has an episode with a whole group of teen "analysts" who are practically playing ''Literature/EndersGame'' in real life.
* ''Series/{{Caprica}}'': Zoe Graystone was raised by two parents who were both brilliant scientists, her father a roboticist and her mother a plastic surgeon. She topped them both by creating an artificial intelligence in her own image at the age of 16.
* Claudia from ''Series/{{Warehouse 13}}'', and painfully aware of it too. Her brother Joshua is her role model for this behavior.
* Dr. Spencer Reid from ''Series/CriminalMinds'' is a former Teen Genius and Child Prodigy. He graduated high school when he was 12 and graduated college when he was 16. He was 23 (turned 24 in the fourth episode) when the series began and Hotch mentioned that he was already working at the FBI for three years. In season 6 he complained about not being allowed to drive when he was in college.
* Allison Baldwin from ''Series/KrattsCreatures''.
* A surprising number of students at the Beacon Hills High School on ''Series/TeenWolf'' qualify for this trope. Stiles is extremely intuitive and exhibits a wide breadth of knowledge on many topics. Lydia is a brilliant chemist, and also knows both archaic and classical Latin (and probably other languages as well). Danny is a skilled hacker and knows how to write software. Matt is a photography/videography expert.
** Interestingly, in each of these cases there's something of a catch though. Stiles has ADD, meaning he's smart but struggles to focus, Lydia hides her IQ to avoid IntelligenceEqualsIsolation (and also [[spoiler: seems to lose a chunk of mental stability with each season]], Danny has a juvenile delinquent record for hacking something he shouldn't have, and Matt [[spoiler: turns out to be a stalker and a serial killer. Sort of.]] It's complicated.
* The 80s sitcom ''Series/HeadOfTheClass'' was about a classroom full of these, learning socialization skills from their ex-hippy teacher.
* In ''Series/ANTFarm'' the [=ANTs=] are part of the Advanced Natural Talents, or ANT, scheme which allows gifted middle-school kids to go to High School several years early. Each child is talented in one particular direction, however: music, art, computers, an eidetic memory and so on. In Main/RealLife of course it's unlikely that their talents alone would allow them to skip grades. The [=ANTs=] are teen geniuses in their individual specialism but not in a more general sense.
* Alvin "Shred" is this in ''Series/MaxAndShred''.
* ''Series/TheBigBangTheory'':
** The main guys (now adults with doctorates) were all implied to be this in their teen years. Sheldon in particular constantly reminds his friends that he was beyond a genius - he was already a P.H.D. by the time he reached his early teens.
** One episode featured a teen prodigy that surpassed Sheldon (and was a refugee from North Korea to boot). The guys "sabotage" him by introducing him to girls.
* ''Series/{{Justified}}'' has Loretta [=McCready=] teenage daughter of the late Walt [=McCready=] and BastardUnderstudy to Mags Bennett, BigBad of Season 2. Since Mags' death, Loretta has secured control over much of Harlan County's weed trade, going up against the likes of Dickie Bennett, Hot-Rod Dunham, and Avery Markham in the process, and consistently coming out on top, due to her ability to play the odds and get {{US Marshal}} Raylan Givens on side.
* The premise of ''Series/WickedScience'' basically relies on this trope.

* Music/LadyGaga wrote her first ballad at thirteen and has been writing music for other artists since the age of fifteen, after having been a piano prodigy.
* [[Music/{{OFWGKTA}} Tyler, the Creator and Earl Sweatshirt]] became cult figures at ages 18 and 16 respectively.
* Music/AphexTwin first started making music by tinkering with his [=ZX81=] home computer at the age of 11, and if the title ''Selected Ambient Works 85-92'' is telling the truth he was already creating his first album by 14.
* Jason Becker could play and write blues at 13; and by the time he was 16, he was able to write songs like [[http://www.youtube.com/watch?v=87Iz3RHZNDQ this]]. To give an idea of how advanced he was, [[Music/{{Nevermore}} Jeff Loomis]] (who is an immensely-skilled and widely celebrated guitarist in his own right) had to practice "Perpetual Burn" for ''months'' and somehow nailed it one day through sheer dumb luck. Loomis is in his forties. Becker was NINETEEN when he recorded it.
** For that matter, Loomis himself. At the age of sixteen, he managed to get an audition with Music/{{Megadeth}} after Jeff Young left and failed to get the job SOLELY because Mustaine felt that he was too young and had too little life experience to be able to handle the rigors of being in an international touring band.

[[folder: Professional Wrestling]]
* Wrestling/LouThesz had already successfully "worked" a match in a legitimate amateur wrestling tournament without anyone catching on before he turned pro at 16. "The Strangler" Ed Lewis decided to instruct young Thesz in hooking, believing he had world champion material, although Thesz wouldn't become a world champion until age 21, which is still younger than anyone else ever had, just too old for this trope.
* In Mexico, Lucha Libre facilitates this with a stricter weight class than say, [[EagleLand that country north of the boarder]], allowing teens who can go to make a name for themselves early and advance through the ranks if they have growth spurt. Wrestling/ReyMysterioJr made his debut at 14, for example.
* The long tenured Dominican Republic wrestler El Bronco #1 of San Cristobal may have started before his teenage years, as he wore a mask to hide his identity after his father protested to "a young child" being in the wrestling business. Young Bronco would go on to lead [[EvilForeigner an invasion]] into WWC on the neighboring island of Puerto Rico.
* Wrestling/LionessAsuka had her first match when she was 16. She won the [[Wrestling/AllJapanWomensProWrestling Zenjo]] Junior title within her first year of wrestling.
* Wrestling/CheerleaderMelissa was actually training and working behind the scenes at shows on the road and her uncle's training school while she was still in high school, completing most of her classes by emailing her teachers. She had her first match on her 17th birthday.
* Wrestling/MattSydal got his wrestling license at age 17, even though his state normally requires you to be 18 before you can apply for one. This would be the basis for a running gag in his Gateway Championship Wrestling career, where he would constantly have his age exaggerated.
* {{Implied| trope}} example in Wrestling/{{WSU}} icon Alicia, who is known for pulling fast ones on ([[OutGambitted almost]]) the entire promotion. The story was she had shown these tendencies since she sought out a wrestling school at 13.
* [[Wrestling/{{Paige}} Britani Knight]] got an early start in the wrestling business at 13, when she was put on the card of a WAW show because a scheduled wrestler could not make it. She started her career in earnest as a [[SubvertedTrope pseudo]] {{jobber}} at 14 and was holding gold by 15.
* [[Wrestling/IvelisseVelez Sexy Juliette The Huntress]] debuted at age 15 and was considered one of the better wrestlers of the Caribbean before she turned sixteen, earning a contract with the International Wrestling Association and program with Amazona, a rookie of 17 at the time who was getting over surprisingly quickly.
* {{Subverted|trope}} in the case of Ta'Darius Thomas, who was a young star in boxing and mixed martial arts but took a long while to get established in professional wrestling. Wrestling/JimmyJacobs offers to help find similar success in pro wrestling [[TheCorrupter in exchange that he uses what he is taught to destroy]] former {{tag team}} partner ACH.

[[folder:Tabletop Games]]
* Ertai, from the "Weatherlight Saga" of ''TabletopGame/MagicTheGathering''; subverted when he's captured and transformed into a half-mechanical monstrosity who hates his former friends. Squee (not ''that'' {{Squee}}), the young [[OurGoblinsAreDifferent goblin]] cabin boy, is also a genius by goblin standards, though by human standards that amounts to "merely functioning".
* Somewhat uncommon, but not unheard of in ''TabletopGame/GeniusTheTransgression''. The slang term for teen Geniuses is a "[[Series/StarTrekTheNextGeneration Wesley]]".

[[folder:Video Games]]
* ''VideoGame/BatmanArkhamOrigins'': 15-year old Barbara Gordon hacks into Batman's comms in order to ask him to help with Penguin weapon shipments. Is it any wonder that she later discovers Batman's identity and becomes Batgirl (and later Oracle)?
* Ciel of ''VideoGame/MegaManZero'' created [[spoiler:Copy-X]], a near-perfect duplicate of [[TechnoWizard Thomas]] [[BigGood Light's]] greatest work, when she was ''six years old'' and devised a completely new energy source before she'd finished her teenage years. ''[[VideoGame/MegaManZX ZX's]]'' backstory indicates she also created the biometals sometime after the Zero series, and on top of everything else she's a HotScientist to boot. [[OmnidisciplinaryScientist Girl gets around, doesn't she?]]
** [[VideoGame/MegaManLegends Tron Bonne]] certainly counts. Aside from the fact that she created the 40 Servbots, most of the machines she makes are made from ''spare parts'', such as a train and Bruno in the first game. She was 13 in the first game (and her spinoff) and 14 in the second.
* Franziska von Karma from the ''VisualNovel/PhoenixWright'' games. Not only is she 18 years old in her debut, but she became a prosecutor at age 13 and went undefeated for five years.
** Klavier Gavin too, although he's no longer in his teens by his first appearance.
* ''Franchise/FireEmblem'' has several of these, some of them being ''very'' important in their plots:
** [[TheHero Roy]] of [[VideoGame/FireEmblemElibe Fire Emblem: Sword of Seals]] is possibly one of the best examples of a GuileHero lord in the series, having a knowledge of politics and how to manipulate them, as well as being able to lead a 50-or-so strong army, despite being one of the youngest ones ever at the ripe old age of 15.
** It's possible for [[PlayerCharacter The Avatar]][[TheStrategist /Robin]] in ''VideoGame/FireEmblemAwakening'' to be this with either the default or the [[MoeMoe younger]] builds; while it's unknown how old he/she is, they don't look any older than in their late teens.
** ''VideoGame/FireEmblemFates'' has Prince Leo of Nohr, Prince Takumi of Hoshido, and potentially [[PlayerCharacter The Avatar]] again. The three are in the mid-to-late teens age range, with the Avatar as the eldest of the three, and yet the three are seasoned and talented fighters. The first two are explicitely referred to as geniuses.
* [[TheHero Shulk]] of ''VideoGame/{{Xenoblade}}'' is a ScienceHero who starts the game working as an engineer/researcher, despite still being 18. The game makes it very obvious that he has somewhat of a name as the local tech whiz.
* ''VideoGame/XenobladeChroniclesX'' has Lin Lee Koo, 13 years old and one of the more well-respected engineers among the entire city. It is made clear very quickly that she is more than qualified for her position, though she isn't perfect by any means (her introductory scene shows a flight test on a system she designed gone wrong when the mech vented exhaust into the cockpit).
* Lucca from ''VideoGame/ChronoTrigger''.
* Coco Bandicoot from ''Franchise/CrashBandicoot'' was a tech-genius well before her teenage years.
* From ''Franchise/ResidentEvil'':
** Rebecca Chambers had graduated from college and joined up with the elite S.T.A.R.S. police force as a medic by the time she was eighteen.
** William Birkin became Umbrella Corp's top scientist at sixteen.
** Carla Radames obtained her Ph.D. in genetics at fifteen.
* Dmitri and Reese of ''VideoGame/BackyardSports'' are younger than teenagers, but they fit the trope.
* Sion Eltnam Atlasia from ''VideoGame/MeltyBlood'', talking about a young teenage girl who can quickly think, she has a mind processing skill equal to that of a supercomputer and can even predict your moves hours or even days before you move.
* Rita from VideoGame/TalesOfVesperia, occasionally to a ludicrous extent. Despite her age she's probably the most intelligent person in the world by a fair margin; her response to a request for a device that would break most known natural laws is essentially, "It'll take until breakfast at least."
* Sachi, one of the heroines of VisualNovel/SharinNoKuni, is explicitly said to have an IQ of 140, is a prodigy-level painter, and something of a math wiz. She pales in comparison to the protagonist, Kenichi, who's in the final stages of what amounts to government sponsored {{ubermensch}} training, which means he has a college level education already, as well as having a resume of accomplishments that'd be impressive for a person of any age. He can expound on complicated concepts at the drop of a hat and has to consciously tone himself down so as not to be an InsufferableGenius.
* Brigid Tenenbaum's backstory in ''VideoGame/BioShock'' has her going from young girl in a concentration camp to [[LesCollaborateurs helping the scientists improve on their work]].
* MadScientist Mao from ''VideoGame/{{Disgaea 3|AbsenceOfJustice}}''. Despite being [[ReallySevenHundredYearsOld several centuries old,]] he's around fifteen by demon standards.
* In ''VideoGame/{{Fallout 3}}'', player character (a 19-year-old) can be this if you use XP right.
** In fact, with high-intelligence and the right perks, one of the first things the player can do literally moments after leaving the Vault is offer to defuse the ''nuclear bomb'' that lies in the centre of Megaton.
* Quistis Trepe in ''VideoGame/FinalFantasyVIII'' is, like [[Franchise/AceAttorney Franziska von Karma]], an eighteen-year old [[WhipItGood whip-wielding]] female genius. She's the youngest instructor in Balamb Garden, having become a [[SuperSoldier SeeD]] at the age of 15. She now lectures students her own age.
* Grunt from ''VideoGame/MassEffect2'' is an odd example. He was genetically engineered to be the ultimate Krogan SuperSoldier, being taught via implanted memories and rapidly aged whilst in the tank. Although he's only a few minutes old when Shepard decants him, he's biologically a teenager, who also happens to possess the intelligence of dozens of millennia-old Krogan Warlords. Naturally, in his spare time, Grunt likes [[GeniusBruiser reading Hemingway]] and playing with ''action figures''.
* All the teen-aged fighters in ''VideoGame/TheKingOfFighters'' have elements of this, but some are more notorious:
** TheProtagonist, Kyo Kusanagi, is said to have properly dominated his pyrokinetic powers and surpassed his father's own skills when he was 15 years old (which is also the time when [[spoiler: his BigBrotherMentor and cousin Souji almost lost himself to his darker side and thus asked Kyo to replace him as the family leader]]). Then, he became the winner of the All-Japan Martial Arts Tournament at age 18, and the Team Japan leader at age 19. The rest is history.
** A subtler example is Yuri Sakazaki. She only started training when she was 16-17, and yet she mastered the basics and low techniques of the Kyokugenryu Karate ''within a year''. She didn't stop there, but started imitating other people's techniques as seen above - and developed her own. (Like the infamous [[ArmorPiercingSlap Hyakuretsu Binta]] and her own Super Special, the ''Hien Hou-oh Kyaku''.)
** The biggest one, however, is Ash Crimson. He becomes the VillainProtagonist, [[spoiler: depowers the much more experienced Chizuru and Iori]], brews one HELL of a BatmanGambit [[spoiler: and reveals himself as a GoodAllAlong figure via saving the world from Those Of the Past when he gets himself and his ancestor {{ret gone}}d]]... while being only in his mid-to-late teens.
* Rouge the Bat from ''Franchise/SonicTheHedgehog'', who is an expert treasure hunter and government agent despite only being 18.
* Little Mac from ''VideoGame/PunchOut'' is a teenage boxing genius, plowing through the ranks of the [=WVBA=] and beating boxers much taller, bigger and stronger than he is at the impressively young age of 17.
* In ''Videogame/LeagueOfLegends'' this seems to be the rule, not the exception, for youngsters in the [[ScienceHero Piltover]]/[[ForScience Zaun]] district. Champions Ezreal (Piltover) and Ekko (Zaun) are the playable shining stars for their respective city-states. Demacia isn't far behind with Lux, a teenage prodigy in magic forcibly recruited into the military.

[[folder:Visual Novels]]
* Makise Kurisu of ''[[VisualNovel/SteinsGate Steins;Gate]]'' is a Child Prodigy-cum-Teen Genius who skipped a number of grades and become a published neuroscientist at the age of eighteen. Unfortunately, [[IntelligenceEqualsIsolation such brilliance has effectively strangled her social life]].
* Chihiro Fujisaki of ''VisualNovel/DanganRonpa'' is an extremely talented programmer who was admitted to Hope's Peak Academy for her abilities. Hope's Peak itself has a policy of only scouting the most talented highschoolers in their given fields - however, this doesn't always mean they're a genius, and some students are outright dumbasses.
* Kotomi in ''VisualNovel/{{Clannad}}''. She doesn't ever attend classes in high school... because she has demonstrated quite clearly that the high school teachers have nothing more they ''can'' teach her: she gets perfect scores on any tests she takes. She spends her days in the library reading up on even more advanced subjects. After graduating, she starts going to an American university and studying alternate timelines and multiple world theory.

[[folder:Web Comics]]
* Junior in ''Webcomic/BloodandSmoke'' is only a high-school student, yet he is a skilled hacker, codes his own programs and is an expert in robotics.
* Tedd in ''Webcomic/ElGoonishShive'' is a Teen Genius overlapping with MadScientist. As time has passed, most of his wacky inventions have been {{retcon}}ned to no longer be his own, edging him out of this trope, but he's still the smartest member of the cast.
** He's still managed to adapt the technology a lot and the Aliens who gave it to him in the first place couldn't even begin to fix it, so his genius title remains.
* Molly & Galatea in ''Webcomic/TheInexplicableAdventuresOfBob'' are both child geniuses, able to perform technological wonders with minimal effort. Considering that they are artificial life forms less than a year old, they are in fact ''very'' young. Molly's personality is overtly and unapologetically childlike. Galatea's speech patterns are [[LittleProfessorDialog much more adult-sounding and pretentious,]] but her naivete still displays her extreme youth.
* Ventura in ''Webcomic/SchlockMercenary'', a nineteen-year-old expert in robotics and AI [[FutureSlang growpramming]]. She also has a moment of CuteBruiser-dom thanks to her company's standard-issue PoweredArmor giving her SuperStrength.
* ''Webcomic/FetchQuestSagaOfTheTwelveArtifacts'': Felicia Whitewind is only sixteen years old, and already she has mastered six of eight ElementalPowers, ''and'' is going to become a mentor. Words cannot describe the sheer [[BadassBookworm awesome]] that exists around her.
* Just a year out of being a Child Prodigy, Kat Donlan of ''Webcomic/GunnerkriggCourt'' is a thirteen year old GadgeteerGenius who designed an anti-gravity device at the age of twelve... which she didn't even find that remarkable, instead getting annoyed when the practical purpose of the device was ignored at the school science fair for the anti-grav device itself.
* Fernando in ''Webcomic/{{Drive}}'' is a subversion despite being the head engineer of his ship at 14. He didn't get the job because of an exceptional intellect, but because he's a member of the Royal Family. Only ''la Familia'' can service the ship's drive, and they're ''badly'' in need of more men.
* ''Webcomic/DubiousCompany'''s Future High Priestess Sal. She is in her late teens and is easily one of the smartest characters in the comic's universe.
** Also, to a [[AlwaysSecondBest lesser extent]], her bodyguard Leeroy. He branched into more physical training after realizing he CantCatchUp.
** [[BunnyEarsLawyer Walter]] and [[TheStrategist Izor]] might have been in their youth.
* Agatha Heterodyne of ''Webcomic/GirlGenius'' is a [[TheSparkOfGenius Spark]] (AKA a super MadScientist). She is eighteen when her PowerLimiter is removed and her power awakens, which makes her a borderline example of this trope. She had briefly been a ChildProdigy in her youth as well, as it was her abnormally early breakthrough that made the PowerLimiter necessary.
* Implied; Annie Chang of ''Webcomic/{{Pulse}}'', the 20 year old WrenchWench engineer has been designing robots and artificial limbs for years. Before her career as a superhero, she repaired equipment at her SuperheroSchool.
* In ''WebComic/CommanderKitty'', while it's a little hard to tell just [[VagueAge how old he is]], Fortiscue is young enough to be both shorter than the main cast and often referred to as a [[http://www.commanderkitty.com/2009/06/12/the-tagged/ "kid"]]. Yet he's singlehandedly created a RidiculouslyHumanRobot, [[CloningBlues cloning technology]], {{nanomachines}}, and [[MilelongShip a giant space lab]].
* Several in ''Webcomic/{{Homestuck}}'', considering most of the cast are thirteen years old. Equius builds robots. Terezi is a skilled manipulator. Jade is a prophet pulling through several {{Stable Time Loop}}s. And Dave manages to keep track of several said time loops in his head. (Granted, he does have help from Terezi.)
** While the Alpha kids are about 16, they still count. Dirk is an accomplished roboticist who designed an AI that very nearly passes the TuringTest. Roxy is a hacker and possibly the only protagonist to come close to Nannasprite's knowledge about [[spoiler: Betty Crocker]]. Jake built [[spoiler: Liv Tyler, aka the Uber-Bunny and he's only the third most talented roboticist]]. Jane hasn't quite shown her credentials yet, but she is the heiress to a multi-global empire.
* With the cream of the crop gathering and being filtered on every floor of the ''Webcomic/TowerOfGod'', these are bound to show up. Special attention goes to [[MagnificentBastard Koon]], who bends the rules at every turn and corner and uses experienced administrators in his schemes, and Baam, whose inherent talent for magic borders to PowerCopying.

[[folder:Web Original]]
* In ''Literature/{{Defection}}'' teenagers with intelligence boosting powers attends special classes in a special school for gifted or connected people.
* The most notable example from the ''Roleplay/GlobalGuardiansPBEMUniverse'' is The Evil Mastermind, leader of Evil Mensa. He's only twelve years old. He is also the third smartest person on the planet, and has already put together his own Criminal Conspiracy that's about an inch away from controlling all crime in Manhattan.
* ''Literature/WhateleyUniverse'': A lot of the devisers and gadgeteers at SuperheroSchool Whateley Academy.
** A good number of the exemplar kids also qualify, due to that nifty "exemplar mental package;" Stopwatch (a CrazyPrepared ClockKing type) comes to mind, as does Diamondback, who has been alluded to as having one of the highest IQ's in the freshman class, if not the whole school. Also Ayla, naturally; he's a teen financial genius, having been learning the ways of business and high finance roughly since he was able to talk.
** Jobe Wilkins, who is not only a frighteningly powerful bio-devisor but also has scads of patents in biological areas. He just developed a cure for dysentery. Problem? He's an amoral monster with all the empathy of a tarantula.
** Kaiju, however, is a genius that doesn't have any powers helping her. She just has the ability to transform into a reptilian form of some kind. As said in [[http://whateleyacademy.net/index.php/original-timeline/372-the-big-idea The Big Idea]]:
--> She’s an electronic genius. Not a devisor or a gadgeteer, but a legitimate genius. She does lovely work. [...] she could be the next Nicola Tesla.”
* Kairan Fisher from ''WebVideo/ChroniclesOfSyntax'' is only eighteen, but is amazing with technology. [[GeniusDitz Daynah]] is this as well, though no specific age is mentioned. They meet at a school for gifted students.
* Noriko Null in ''Literature/BeyondTheImpossible''.Somewhat downplayed by the fact that she [[IntelligenceEqualsIsolation immediately drops out of school and leaves all her “normal” friends behind]].

[[folder:Western Animation]]
* In ''WesternAnimation/{{Daria}}'', the titular character, Jane Lane and Thomas "Tom" Sloane. Jodie Landon as well, who was once selected along side Daria as possible candidates for a school for gifted intelligence.
* ''WesternAnimation/BatmanBeyond'': Maxine "Max" Gibson, who acts as Terry's SecretKeeper, tutor, and Alfred. She is also a strategist and thoroughly understands tech. There's also that highest-scoring student in the school thing.
* Jeremie from ''WesternAnimation/CodeLyoko'' (though angst is more Ulrich's department). Aelita certainly also qualifies in this area (but she's [[OlderThanTheyLook older than she looks]]).
** She's only chronologically older. Being a SealedGoodInACan made her not age past 11-13, and she was in stasis for 10 years, which makes one assume that she wasn't aging in any sense.
* In ''WesternAnimation/TransformersAnimated'', Sari became one of these in Season Three thanks to upgrading herself into a {{Technopath}}.
* [[EnsembleDarkhorse Noah]] from ''WesternAnimation/TotalDrama''.
* Cyborg from ''WesternAnimation/TeenTitans'', most of his angst derived from his [[WhatMeasureIsANonHuman cybernetic limbs]].
** Actually all of the WesternAnimation/TeenTitans are teen geniuses in some way, but Robin, who angsts over everything, is a pretty straightforward example.
* Johnny's twin older sisters, Mary and Susan, in ''WesternAnimation/JohnnyTest''.
* Velma from ''ScoobyDoo''.
* Cody and Starlee from ''[[WesternAnimation/TeenageMutantNinjaTurtles2003 Teenage Mutant Ninja Turtles: Fast Forward]]''.
** Donatello himself. TEENAGE Mutant Ninja Turtles, remember?
* Cosmo from ''WesternAnimation/TheMagician''.
* Alan and Tom Chan in ''WesternAnimation/TheAmazingChanAndTheChanClan''; Alan of the mechanical sort, Tom of the intellectual sort.
* Heloise from ''WesternAnimation/JimmyTwoShoes'', who works for a MegaCorp at [[VagueAge 14-ish]].
* Moonrock from ''WesternAnimation/ThePebblesAndBammBammShow''.
* Valerie from ''WesternAnimation/JosieAndThePussycats'' comes with some intellectual chops.
* ''WesternAnimation/{{Futurama}}'s'' Cubert Farnsworth, given he is a teenage clone of Professor Hubert Farnsworth. Possibly Dwight Conrad (Hermes' son) also, as he and Cubert were smart enough to run their fathers out of business.
* ''WesternAnimation/IronManArmoredAdventures'' is focused on Tony Stark's teenage life. In this incarnation, he's already developed Iron Man armors.
* Dotty from Hanna-Barbera's ''WesternAnimation/ClueClub.'' A forensics expert at age 13.
* [[TheDragon Princess Azula]] from ''WesternAnimation/AvatarTheLastAirbender''. At the age of 14, she is arguably the greatest strategic mind in the series, at one point juggling about four different complications into a single grand plan. It ends with her brother switching back to her side, TheHero (temporarily) dead, and Ba Sing Se, a city that had withheld 100 years of siege, conquered, all starting with just her and two BadassNormal friends.

* John Stuart Mill was raised by his economist father John Mill and philosopher Jeremy Bentham (each of whom was a genius in his own right) as an experiment for Bentham's ideas on education and to create the genius they needed to carry on their work in utilitarianism and ethics. J. S. Mill could read Greek by the age of three, and he was so well-versed in economics and political theory that he was editing and writing his father's textbooks by the age of eleven. He had a nervous breakdown by the age of twenty, but eventually recovered.
* Scottish mathematician Colin Maclaurin was in the University of Glasgow by 11, and had his master's degree at 15.
* George Hotz - aka, geohot - unlocked the iPhone during his summer vacation.
* Growing up in the Caribbean, UsefulNotes/AlexanderHamilton was so brilliant that his employer trusted him to run his import-export business for months at a stretch. He was either 15 or 17 at the time, depending on whether or not he'd lied about his age to improve his employment prospects.
** On the opposite side of the coin, Aaron Burr. He applied to Princeton at the age of 11, and he would have been accepted on his academic prowess too except the trustees stepped in and overruled him. Undeterred, Burr studied through Princeton's freshman and sophomore (1st and 2nd year) curriculum at home and reapplied to Princeton for the junior (3rd year) class. The school faculty compromised and allowed him to join the sophomore class. Burr entered Princeton at age 13 and graduated at 16.
* William James Sidis could read the New York Times at 18 months and earned his Bachelor of Arts degree at Harvard University, cum laude, at age 16.
** Later popularly reported as suffering a "burnout", the evidence points to his just getting fed up with being put on public exhibition all the time. After his death a friend wrote that he "had one great cause -- the right of an individual in this country to follow his chosen way of life".
* Kim Ung-Yong of Korea was said to have a Terman IQ of 210. He started out as a Child Prodigy. He was hired by NASA at age twelve and worked for them until he was eighteen, in a job he later called "incredibly boring". Returning to Korea he now teaches civil engineering.
* French mathematician and physicist Blaise Pascal started to manifest his talents when he was 9 years old, and grew to be an accomplished scientist by ''the age of 19''.
* Creator/BenjaminFranklin. He wrote lively and entertaining letters for his brother's newspaper -until said brother found out who was contributing them. After moving to Philadelphia, he eventually began helping Thomas Denham as a clerk, bookkeeper, and shopkeeper.
* In the UsefulNotes/{{Philippines}}, there are high schools specifically designed for geniuses in science and technology. In Metro Manila, there's one in almost every city, but there's also the Philippine Science High School, which spans nationwide. And every high school graduate in the countrys enter college at 16, at least until the K-12 program is implemented nationwide.
* Frederic Chopin composed his first rondo at age 15.
* German Field Marshal UsefulNotes/ErwinRommel, at the age of fourteen, was building and piloting his own gliders, as well as dismantling and rebuilding motorcycles.
* Not a teen for much longer, but here for your viewing, one [[http://www.nbcnews.com/video/rock-center/52207962 Taylor Wilson]]. He built a working fusor at ''14'' This kid is ''going'' places, and places that either charge high tuitions or pay astronomical salaries (or both).
* Music/TomLehrer, of all people, earned a bachelor's degree in math from Harvard at the ripe old age of 19.
* Music/WeirdAl graduated high school at 16, as Valedictorian.
* Margaret Emily Shore (1819-1839), naturalist, artist, [[WorldBuilding World Builder]], playwright and novelist. Like ChildProdigy Thomas Malkin[[note]]she was a fan of his brother Frederic's history textbooks[[/note]] she was the homeschooled ChildProdigy offspring of a clergyman at Bury St. Edmunds in England, and zoomed right along until age nineteen when she died of tuberculosis complicated by a stroke. [[http://babel.hathitrust.org/cgi/pt?id=uc1.$b275001;view=1up;seq=1 She left copious diaries]], which unfortunately were edited by her surviving sisters into something more fitting to Victorian propriety. Out of the dozen or so volumes, we have about a fifth of her work. She is the subject of a song by Music/TheHandsomeFamily and an ongoing attempt by Women's Studies professor Barbara Timm Gates to [[http://rotunda.upress.virginia.edu/EmilyShore/make-page.xqy?id=jes-intro restore her work.]]
* Creator/{{Ouida}}, also born in Bury St. Edmonds, wrote her first novel ''Idalia'' at sixteen although it didn't get published until twelve years later.
* Anthropologist, poet, sculptor and Mexico scholar Robert H. Barlow got started in these interests as a child, isolated and homeschooled in the Florida swamps. He is probably best known as a friend (and literary executor) of Creator/HPLovecraft; from the age of 13 he and the Old Gentleman wrote copious letters and visited each other as often as they could afford it. [[note]]He was also gay, and HPL biographer W. Scott Poole believes he may have been in love with HPL.[[/note]]
