* Applies to both Shizoku and Fuyuko in "Literature/NoNeedForACore?". Shizoku is a thirteen-year-old, three-tailed, prodigy kitsune witch, and Fuyuko is a fourteen-year-old [[Spoiler:part-oni, part-lycan]] street orphan who manages to solo-kill a [[OurPerytonsAreDifferent peryton]], though she would have died too if not for some [[JustinTime timely intervention]].

* ''Fanfic/AbraxasHrodvitnon'': [[Characters/AbraxasHrodvitnonHumans Madison Russell]], like in [[Film/GodzillaKingOfTheMonsters2019 her movie appearance]]. Still dealing with the PTSD of everything she went through, she doesn't think twice about [[DidYouJustFlipOffCthulhu flipping off]] a former head of Ghidorah (the 500-foot dragon which traumatized her) in anger, and she's willing to use the ORCA to [[LoudOfWar disorient]] [[spoiler:Keizer Ghidorah]] at the FinalBattle.

* Franchise/MonsterVerse: [[Characters/MonsterVerseMadisonRussell Madison Russell]] is a petite-sized teenage girl who is often regarded by adults around her including her father as a hapless little girl who poses no real threat and doesn't know what she's talking about half the time (no matter how much she's being the OnlySaneWoman). However, she also has survival training due to her upbringing in Monarch, and guts that even the {{Kaiju}} could probably admire; stealing the ORCA from a radical EcoTerrorist paramilitary and using it to stop a global Titan rampage at the cost of getting King Ghidorah (basically Kaiju Satan) personally pissed at her in ''Film/GodzillaKingOfTheMonsters2019'', and personally leading her friend and a grown man in an infiltration of [[EvilInc Apex Cybernetics]] to expose their shady secrets because no-one else will in ''Film/GodzillaVsKong''.

* ''Literature/{{Worm}}'': Missy Biron, a.k.a. Vista, is the youngest member of Brockton Bay's Wards[[note]]The government-run program for junior superheroes[[/note]] team. She is also the ''longest-serving'', and due to [[WretchedHiveOfScumAndVillainy Brockton's supervillain-lead-gang problem]] and chronic manpower shortage in the Protectorate[[note]]The adult superhero organisation[[/note]] their Wards team regularly sees serious action (contrary to the program's nominal purpose as a safe way for superpowered youths to get training and assistance); she once took on Hookwolf, one of the most dangerous and vicious Villains in the city, solo. She also has the highest PRT[[note]]Parahuman Response Team, the non-powered police force for dealing with superpowered crime[[/note]] [[PowerLevels threat rating]], not merely of the Wards, but of ''all'' the Heroes in the city.

* ''VideoGame/SengokuBasara'' has Itsuki, the tiny adorable leader of the northern peasant revolution. She loves rice, beating the crap out of some of the scariest samurai around with her [[DropTheHammer humongous hammer]], and inspiring oddly sweet moments with the game's resident MrFanservice BloodKnight.

** Also, Ginny Weasley will own anyone with her famous Bat Bogey Hex. In the ''[[Literature/HarryPotterAndTheOrderOfThePhoenix Order of the Phoenix]]'' she '''annihilates''' objects with a "reducto" spell.

* Small blonde Camikazi from ''Literature/HowToTrainYourDragon''. Well, she is the heir to a tribe of BrawnHilda warriors.

* A disturbing example of this pops up in the ''Series/{{Firefly}}'' fanfic ''Fanfic/{{Forward}}'' in the form of Inducer One-One-Nine. While not as overtly powerful as, say, [[WaifFu River]], she makes up for it by having terribly powerful MindManipulation powers coupled with frightening subtlety - and is psychotic enough to be an EnfantTerrible too.

* Ivy the Archive from ''Literature/TheDresdenFiles''. She has had the collective written knowledge of humanity filed away in her mind ''since birth'' -- every fiction and non-fiction book, play, story, poem, speech, script, documented scientific formula for deadly biotoxins, classified document, and nuclear launch code, all recorded knowledge of magic -- and knows how to use it. The White Council thinks she's a peer to the youngest (and thus, weakest) Queens of the [[TheFairFolk Faerie Courts]], but the main character Harry — probably the only living member of the White Council who has seen the Archive in action — says they underestimate her. To put this into perspective, in ''Small Favor,'' [[spoiler: the BigBad for the book sets off an EvilPlan to capture her while she's isolated in a building and sealed off from magic. She holds off at least ten Denarians, badass sorcerers even without [[OurAngelsAreDifferent fallen angels]] in their heads. And she does it all with a RestrainingBolt. To add to this, just to conjure enough power to create the RestrainingBolt alone required them calling on {{Satan}}]]. And further perspective must be said, [[spoiler:the BigBad and his crew who set up the trap to bind her here, and later as a prisoner, didn't have enough power to do it. They have to tap into a massive ley line to supply them with the power]]. WordOfGod holds that [[spoiler:all her claims of being there if an apocalypse happens and human knowledge is lost, is a lie. Her purpose is to fight ''Old Gods'' in the Oblivion War. Using different groups in separate cells, she has them hunt down the worshipers and documents that have the Names of ancient evil gods and destroys them. She then seals the knowledge within her and then she waits a few hundred years and if no mention has popped back up, no one can remember that ancient god, she deletes the information from herself and that god is now banished forever]].

* Bastille from Creator/BrandonSanderson's ''Literature/AlcatrazSeries'', at age 13, is the youngest person to have become a Knight of Crystallia. Her training and being bonded to certain crystals makes her incredibly fast and strong. Underestimate her and you'll be at the receiving end of her massive crystal sword, or at least her handbag.
* Between the expertise and the body count, Sarah from ''[[Literature/{{Duumvirate}} Billy & Howard]]'' exemplifies this trope. Halfway through the second book she grows into a LadyOfWar.

* Creator/NealStephenson's [[PostCyberpunk post-cyberpunk]] novel ''Literature/TheDiamondAge'':

* Ivy the Archive from ''Literature/TheDresdenFiles''. She has had the collective written knowledge of humanity filed away in her mind ''since birth''--every fiction and non-fiction book, play, story, poem, speech, script, documented scientific formula for deadly biotoxins, classified document, and nuclear launch code, all recorded knowledge of magic--and knows how to use it. The White Council thinks she's a peer to the youngest (and thus, weakest) Queens of the [[TheFairFolk Faerie Courts]], but the main character Harry — probably the only living member of the White Council who has seen the Archive in action — says they underestimate her.

* It's glossed over, as it happened about eight years before the book actually starts, but the protagonist of ''Literature/GracelingRealm'' once killed her perverted distant cousin ''with one blow. When she was eight''.

* In Creator/RobertAHeinlein's ''Literature/HaveSpaceSuitWillTravel'', Kip Russell, the narrator of the story, discovers that little [=PeeWee=], whom he didn't judge as much, just a harmless little girl, has been helping the Mother Thing build a bomb -- knowing that it is a bomb -- which is capable of killing all of the [[BigBad Wormface]]s, as well as a radio beacon to summon the Mother Thing's people for help.
* Helen Zilwicki, in her first major appearance in the Literature/HonorHarrington stories, is twelve years old, and she kills a couple of men who attempt to rape her, with her bare hands.
* Huge armies of Little Miss Badasses are the focus of Creator/HenryDarger's monumental fantasy novel
''Literature/InTheRealmsOfTheUnreal''. The child slaves of Glandelinia are incited to rebel by five-year-old Annie Aronburg, who promptly becomes a John Brown-like martyr to the cause of abolition. The seven daughters of Emperor Robert Vivian of nearby Abbieannia join Annie's sister Gertrude and become leaders and inspirational figures to the rebel children. Expect GirlsWithGuns and lots of ChildSoldiers.

* Kirsty from ''Literature/JohnnyMaxwellTrilogy''. She left the local karate club because no boy would dare to come near her.

* Lily, in ''Lilliput'' by Sam Gayton. Underestimated by almost everyone, since she's only a few inches tall and a child, after being kidnapped at the age of six, she almost immediately begins hatching escape plans. Later she goes into battle against (to her) giants armed with a sewing needle as a sword--and wins.

* Rye's toddler sister Lottie in ''The Luck Uglies''. Her eagerness to leap into a fight with a ladle and pot helmet is PlayedForLaughs most of the time, but when a corrupt constable with a hobby of harassing her mother won't back down, the little girl takes her mother's ChastityDagger and ''stabs the officer in the foot''. It only aggravated the situation, but quite the feat for a kid still in potty training.

* Alice Dare and Josephine Jerome in ''Mars Evacuees'' by Sophia [=MacDougall=]. Sent to Mars as cadets to fight in a war against aliens invading Earth, they wind up only having a few months of training. They learned their lessons well.
%% * Angel from ''Literature/MaximumRide''.
* Most of the female Meq in ''The Meq'', since the majority of them are [[ReallySevenHundredYearsOld over a thousand years old]]. Geaxi probably tops them all though and definitely fits the trope best.
* ''Literature/MillenniumSeries'': Lisbeth Salander ''is'' this trope.
* Likewise 12-year-old Hazel Meade (later Stone) in ''Literature/TheMoonIsAHarshMistress''.
* The Literature/PaladinOfShadows books have Creata. Described as small and delicate, she disembowels a sex slaver with a drilling laser in ''Choosers of the Slain'' and calmly blows his brains out afterward.
* Basically all of the female demigods in ''Literature/PercyJacksonAndTheOlympians'' fit this trope. Most of the Aphrodite daughters don't really do anything, but some special mention must go to [[spoiler:Silena Beauregard. Even though she's not a badass when compared to the other characters, she attacks a drakon (basically a dragon but worse) head on, despite the fact that she definitely is not the best fighter]].

* In ''[[Literature/TheSquiresTales The Princess, The Crone, and the Dung Cart Knight]]'', thirteen-year-old Sarah sees her family burned at the stake. Her response is to try and [[RefugeInAudacity steal Sir Kai's sword]] so she can go after the man who instigated the mob. Kai is so impressed by this that he gives her the sword meant for his son (she's only thirteen, so it fits her better than his broadsword), and she not only exacts revenge on the man who started the mob, but the man who was giving ''him'' orders -- ''by facing him in single combat.''
* In ''Literature/RachelGriffin'', the titular Rachel, a thirteen year old girl, is capable of calmly faking {{Brainwashing}} in order to get the drop on [[spoiler: the demon-possessed BigBad]] and shutting him down.

* Although she's not a prominent character, a girl named Kym in ''Return of the Emperor'' is a major example. She uses her looks (and her weapons) to knock out unsuspecting men and steal their stuff. She is used as part of the base for a smear campaign against Dusable's moron of a ruler.
* From Creator/JohnRingo:
** As part of a BadassFamily, Callie O'Neal in the series ''Literature/TheLegacyOfTheAldenata'' is skilled in many forms of violent mayhem, coached mostly by her RetiredBadass mercenary grandfather, at all of 13 years of age.
** In the ''Literature/BlackTideRising'' series, Faith is 13 years old, a bit taller than the norm for that age, and takes on herds of zombies thanks in part to training from her former special forces soldier father.
* From ''Literature/TheSistersGrimm'' series: Sabrina, the self-proclaimed "Queen of the Sneaks" and her sister Daphne.

* Jane, a millenarian vampire from ''Literature/{{Twilight}}'': despite having the appearance of a little girl and a very childlike voice, she is still extremely feared and respected by all the others vampires around her.

* Tiffany Aching, in the Creator/TerryPratchett novel ''Literature/TheWeeFreeMen''. Hell, she's nine years old, and takes on TheFairFolk with a FryingPanOfDoom!

* Emilia in ''[[Literature/SitioDoPicapauAmarelo Yellow Woodpecker Farm]]'' is actually a living ragdoll rather than a actual human girl, but she still qualifies, being exceptionally independent, headstrong and capable of [[RealityWarper warp reality with the power of make believe]].

** Not that this particularly matters when it comes to Carmela... Seriously, she can come walking casually into the Rirhath B Crossings Station in an awesome outfit ... right after the Crossings have been blown up in an effort to get rid of alien mercenaries threatening Instant Death ... and [[spoiler: get rid of the aforementioned aliens using a bar of chocolate.]]

* ''Literature/{{Worm}}'': Missy Biron, a.k.a. Vista, is the youngest member of Brockton Bay's Wards[[note]]The government-run program for junior superheroes[[/note]] team. She is also the ''longest-serving'', and due to [[WretchedHiveOfScumAndVillainy Brockton's supervillain-lead-gang problem]] and chronic manpower shortage in the Protectorate[[note]]The adult superhero organisation[[/note]] their Wards team regularly sees serious action (contrary to the program's nominal purpose as a safe way for superpowered youths to get training and assistance); she once took on Hookwolf, one of the most dangerous and vicious Villains in the city, solo. She also has the highest PRT[[note]]Parahuman Response Team, the non-powered police force for dealing with superpowered crime[[/note]] [[PowerLevels threat rating]], not merely of the Wards, but of ''all'' the Heroes in the city.
* [[TheOldGods Ryn]], the main character of Literature/TheOneWhoEatsMonsters, looks like a slightly underfed five-foot tall, sixteen-year old girl who weighs "one hundred and three pounds." She's actually the oldest monster in the world, can throw cars at people, can not only catch bullets but ''redirect'' them, and has claws that look like fingernails but are so sharp they can cut ''souls''. And the title of the book? ''Not'' metaphorical.

* Sunny in ''VideoGame/MetalGearSolid4GunsOfThePatriots'' and again in ''VideoGame/MetalGearRising''.

* ''Film/{{Serenity}}'': River Tam. She's a teenage girl and a genius skilled in everything, and she's also a psychic. She's messed up because the Alliance played with her brain and turned her into a super soldier.

* Lily Flyer from ''VideoGame/FZero GX'' certainly qualifies, considering that she's military-trained, has served as support in wars, and is competing in the F-Zero championship with what is essentially a modified tank at the age of 14..

** Note that all of these except for the first two (which were accidents) happened after the mass {{Flanderization}} of all characters. [[Administrivia/TropesAreTools Tropes Are Not Bad]], indeed...

* ''VideoGame/SonicTheHedgehog'' has Amy, Cream and Blaze, who are respectively 12, 6 and 14 years old (even though Blaze is YoungerThanSheLooks). Despite their young age, all of them are more than capable of kicking plenty of ass [[BadassAdorable and get an "awww" out of players in the process]].

* ''VideoGame/BlazBlue'': Carl Clover is a top-class vigilante able to manipulate and communicate with a centuries old arch-enemy event weapon hellbent on getting revenge on his [[MadScientist father]]; he is said to be the strongest vigilante by NOL's records, surpassing biological weapon Taokaka and ninja Bang Shishigami. The boy isn't even a teenager.
