History Main / TeenGenius

* 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]].

** ''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.

* [[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]].

* A good chunk of the cast of ''Manga/KaguyaSamaLoveIsWar'' are geniuses, with [[StudentCouncilPresident Shirogane]], [[TheOjou Kaguya]], and [[ButtMonkey Maki]] as the top three ranked second year students [[spoiler:[[EliteSchoolMeansEliteBrain who all go on to attend Standford University after graduation]]]] ([[NiceGirl Kashiwagi]] used to be fourth, but her grades progressively got worse over the course of the series due to spending most of her study time helping her boyfriend). [[MoralGuardians Miko]] is ranked first among the freshmen, and [[BrilliantButLazy Ishigami]] is GoodWithNumbers.

* 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.

* Rouge the Bat from ''VideoGame/SonicTheHedgehog'', who is an expert treasure hunter and government agent despite only being 18.

* Maggie Sandiego from ''Fanfic/{{Parthenogenesis}}'' shares her mother Carmen's wit, helped by her growing up in [[ReallyMovesAround various countries]]. She even beats Carmen's ACME exam score (the previous highest) just for kicks, because she wanted a challenge.
* ''Fanfic/OfSiblingsAndMasks'': Nunnally is very capable, both intellectually and as [[AChildShallLeadThem a leader]]. Suzaku guesses that capability runs in her family, because her brother Lelouch was similar.
* While being a regular human in ''Fanfic/HeroesInTheShadows'', Donatello is just as intelligent as his [[WesternAnimation/TeenageMutantNinjaTurtles2012 canon]]-counterpart. Unfortunately, this makes him an ideal asset to the Kraang, who try to kidnap him along with April because they think he could help them perfect their mutagen.

* The ''Anime/PrettyCure'' franchise has at least two of these: Yukishiro Honoka from ''Anime/FutariWaPrettyCure'' and Minazuki Karen from ''Anime/YesPrettyCure5''.

* 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]].

* Theresa "Tessa" Testarossa, Sagara Sosuke, 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.

* 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]].

* Subverted in ''LightNovel/RebuildWorld''. Due to others being unaware of Alpha's existence, Akira's wild success as a hunter is attributed to him being a naturally gifted prodigy. In truth, it's Alpha's guidance, constant training drills, and in-combat support that give Akira the edge he needs to succeed against otherwise impossible odds.

* In ''LightNovel/StarshipOperators'', even you're a veteran tactician, you do not mess with Shinon Kouzuki. Trust us, it's a very bad idea fighting her.

%%* Huey Laforet of ''LightNovel/{{Baccano}}'' was a Teen Genius in ''1705''.

** ''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.

* Fernando in ''Webcomic/DriveDaveKellet'' 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.

* 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.

* Frederic Chopin composed his first rondo at age 15.

* Music/WeirdAl graduated high school at 16, as Valedictorian.

* From ''Franchise/ResidentEvil'':
