%% One quote is sufficient. Please place additional entries on the quotes tab.

She has skills that far exceed what you'd expect from her appearance. Maybe it's because she is a bit strange, [[WiseBeyondTheirYears mature for her age]], or [[ReallySevenHundredYearsOld doesn't look like her age at all]]. Vaguely similar to a {{Tykebomb}} save she isn't necessarily groomed by a BigBad, and may well be a Big Bad in her own right or at least TheDragon. Might be the [[TheBigGuy fighting powerhouse on the good guys side]] and can be mistaken for just the TagalongKid until she unleashes the WaifFu.

The character may be quite cute and is often smart enough to [[DeliberatelyCuteChild use that to her advantage]], [[FilleFatale quickly manipulating anyone]] stupid enough to [[ObfuscatingStupidity fall for her act]]. Her actual personality will usually be very clever and cynical, though. She may also be more innocent or good-natured, but no less charming so that she generally gets her way. [[ElegantGothicLolita Often extends]] [[EverythingsBetterWithZippers to what ]] [[NiceHat she is]] [[TooManyBelts wearing]], [[RummageSaleReject if she cares at all]].

If put into serious danger she can often show an absurd amount of power and will easily deal with any annoying perverts in the most casually devastating way possible. Often a practitioner of WaifFu, and can be an example of SmallGirlBigGun or GirlWithPsychoWeapon. Can be a CuteBruiser and/or a PintSizedPowerhouse, but doesn't rely on brute strength. If she doesn't have ridiculous strength, she would be WeakButSkilled. Most noticeable in characters who look very young, since many characters tend to catch on to overpowered teenagers much quicker.

Compare EnfantTerrible. May belong to a BadassFamily. May grow up to be a LadyOfWar, although often with a touch of FemmeFatale. If lacking in charisma, she would be an ActionGirl, or possibly DarkActionGirl.

Contrast BadassAdorable and TykeBomb; the distinction being that the Little Miss Badass is never restricted by a guileless disposition and can occasionally be found reveling in her own badassery, veiling her ruthlessness only when it suits her.

See also TroublingUnchildlikeBehavior, which some of these characters engage in.



[[folder:Anime & Manga]]
%% * ''LightNovel/AccelWorld'''s Nico isn't known as the Red King because it happens to be her favorite color...
* The quiet, petite Kirino Kotori of ''Manga/AiKora'' turns out to be HeirToTheDojo of a ninja clan, and also has a rather nasty temper on her.
* Angel/Tenshi/Kanade Tachibana from ''Anime/AngelBeats''. She's as close as you can get to a [[VideoGame/StarCraft Protoss Zealot]] ''and'' [[Film/TheMatrix Agent Smith]] packed in a small girl's body, although isn't evil like the latter and isn't an alien like the former.
* ''Manga/AttackOnTitan'''s Mikasa had bullies run scared just ''seeing'' her and isn't shy about [[BrightSlap punching friends out]] (or throwing them against walls) when needed, and ranked 1st in the army academy amplitude test. [[TookALevelInBadAss We can all thank]] [[spoiler:Eren]] [[TookALevelInBadAss for that]]
* Sweet, adorable and harmless [[spoiler: Elizabeth "Lizzie" Middleford]] of ''Manga/BlackButler'' [[LadyOfWar turns out to be one]] when it's revealed in Chapter 57 [[spoiler:that because she didn't want her [[ChildhoodMarriagePromise fiancé]] Ciel to see her "uncute" side, she [[DeliberatelyDistressedDamsel deliberately hid]] her badass side and did a very good job of it until, finally, when Ciel despite his best efforts ends up [[DistressedDude injured and unable to save her]], Elizabeth candidly leaps into the air and [[WaifFu takes down the zombies]] with [[DualWielding swords in both hands]], saying that she will save him and become the wife of the Queen's Watchdog.]]
* Eve in ''Manga/BlackCat''. She can turn her hair into nano-blades and cut you at a particle level.
* Gretel in ''Manga/BlackLagoon''. Despite being only 11 years old she has the ability to run and fire a [[{{BFG}} Browning Automatic Rifle]] to great effect as well. [[spoiler:She might be a cross-dressing boy though. Similarly, her "brother" may fit this trope...]]
** What we see of Revy's childhood also fits this trope.
* ''Manga/{{Bleach}}'':
** Yachiru looks about 6-7 and uses her cutesy antics to get many things more serious people would never give her and is obsessed with sweets. She usually just rides around on Kenpachi's back and lets him do all the fighting, but she's second-in-command of the most violent {{Shinigami}} division, is capable of incredible speeds that catch even famously swift characters by surprise, and has extraordinary battle instincts that make her a powerful, dangerous fighter in battle.
** Nelliel looks like a helpless little toddler, whose most dangerous ability is her loud wailing whenever Ichigo tries to leave her behind somewhere safe. However, she's capable of capturing the ceros of very powerful Espada, swallowing them and regurgitating them back at the enemy. She's an ex-Espada, trapped in the form of a tiny toddler by an unhealed injury. Agitate her enough, and she can transform into her true adult form which allows her to access her full power for a very short period of time before her unstable, broken power collapses back to the toddler form.
* Meiling/Meilin of ''Manga/CardcaptorSakura''. Took on the Fight Card (that is, a supernatural being created to do nothing but fight, and to do it well) in hand-to-hand combat, knowing full well that she couldn't beat it, just to distract it long enough for Sakura to figure out how to seal it. She literally almost got killed in the process, but it was CrazyEnoughToWork.
* ''LightNovel/ACertainMagicalIndex'' and ''Manga/ACertainScientificRailgun'':
** Misaka Mikoto is the third strongest Esper for a reason.
** Her roommate and AbhorrentAdmirer PsychoLesbian StalkerWithACrush, Shirai Kuroko, is also one, as she once took down an armed bank robber many years older and much larger with a series of well executed martial arts moves. His partner took a bit more effort after he caught her off guard, but the situation ended with her hand on his face and her asking him if he wanted to bet if his power or hers were faster.
* ''Manga/{{Claymore}}'' has more of these than it knows what to do with. There's the sweet and positively precocious Riful, one of the most powerful awakened ones in existence. Her favorite hobby is having her boyfriend torture people into going OneWingedAngel. Then there's the other BigBad, Priscilla. Just like Riful she's cute as a button but, again, she's probably going to eat your soul. After the TimeSkip they threw in Miata who mixes it up by being just this side of AxCrazy.
* In ''Anime/CodeGeass'', Anya Earlstreim is one of the highest ranked knights in Britannia and pilots one of the biggest mecha yet seen... Yet she's barely 15 years old and looks about 12. Nunnally in the spin-off ''Manga/CodeGeassNightmareOfNunnally'' covers Anya's narative position in that work.
* ''Manga/DGrayMan'''s Road Kamelot is only 12 years old -- and yet she is one of the most fearsome villains. She's very powerful and is able to manipulate space. Her hobbies include playing, eating candies, and driving people insane. [[spoiler:It's possible that she's also multidimensional, as she mentions that she can teleport without using the Arc because she exists both in the real world and the world she lives in, which just so happens to be scary and nightmarish.]] And then it turns out that [[OlderThanTheyLook she only looks like a child.]] [[spoiler:She's the second eldest Noah after Adam, aka the Millennium Earl, and has looked 12 for the last 35 years.]]
* From ''Manga/DanceInTheVampireBund'', we have Mina Tepes, the Princess of all Vampires. She looks like a 10 year old girl [[spoiler: when not in her true form]] but is several centuries old. She can also kill you in many different ways.
* Emily from ''Manga/TheSeveringCrimeEdge'' is among the youngest Authors and is very skilled with her killing good. She even manages to curb-stop Kiri twice.
* Suou in the second season of ''Anime/DarkerThanBlack'' is getting there, thanks in part to time spent [[TrainingFromHell being yelled at]] by a supreme badass and in part to the SmallGirlBigGun effect.
* Daida "Punishment" Hibana in ''Manga/DeadmanWonderland'' is a psychopathic kindergartner who was sent to the prison after dismembering several of her classmates. Brought up by her deranged mother to believe that injuring people helps them grow up, she wields a {{BFS}} twice her size with no apparent effort.
* Ai Haibara in ''Manga/DetectiveConan'', despite being [[OlderThanTheyLook older than she looks]], is ''absolutely'' one. How often do you see an apparent first-grader calmly leveling a handgun at someone?
* Ruki Makino in ''Anime/DigimonTamers'', complete with BadassLongcoat and CoolShades in her debut.
* Cisqua of ''Manga/ElementalGelade'', who even the author implies has access to possibly infinite amount of space in her cape and ''hat''. And what does she use all the space for? Guns, missiles, bombs... anything that explodes.
%% * ''Manga/ElfenLied'' has the diclonii. Almost all of them go through a stage of been this.
* ''Manga/FairyTail'':
** Wendy, when she gets over her shyness and insecurity.
** At her first appearance, Merudy is a much smaller girl than other girls like Erza and Juvia, but she seems to be slightly bigger than Wendy, yet she is one of the most powerful wizards of the strongest dark guild in the whole region. [[spoiler: During her battle against the 2 Fairy Tail mages, she initially easily swept away Juvia and even came close to beating the mighty S-Class mage, Titania.]]
** Mavis Vermilion, Fairy Tail's first guild master, is capable of [[TheChessmaster planning]] an entire city-wide [[ParallelConflictSequence battle between eight five-man teams]] based on [[BatmanGambit how]] ''[[BatmanGambit everyone]]'' [[BatmanGambit will act and react]]. And that's not all: She is one of the most powerful characters in the series, to the point where she was voted Guild Master by Precht Gaebolg/Hades (the ArcVillain of the Sirius Island Arc and the GreaterScopeVillain of the first major portion of the series), Warrod Sequen (a member of the [[WorldsStrongestMan Four Gods of Ishgar]]), and Yuriy Dreyar, the father of the ''current'' master of Fairy Tail. And as if that wasn't enough, she was trained in magic by none other than [[spoiler:[[TheDreaded The Black Wizard]] [[BigBad Zeref]] himself. Whom she [[DatingCatwoman was in love with]] until he TookALevelInJerkass.]]
** Sherria Blendy, the Sky God Slayer, is essentially Wendy but more confident and with [[YouGottaHaveBlueHair pink hair instead of blue]].
* Veronica from ''Manga/FrankenFran'', an ArtificialHuman with the body and personality of a preteen girl...and a healthy variety of weapons integrated. She also has a rather low killing threshold.
* May Chang in ''Manga/FullmetalAlchemist'' has [[ChineseGirl cute braids]], a [[HeadPet little panda]] and very good manners. She also keeps pace with Scar and Ed when fighting off monsters.
* Mint Blancmanche in ''Anime/GalaxyAngel'', although she's actually a teenager (just barely, at 15), who [[OlderThanTheyLook just happens to look young]]. Though you really have to get on her bad side to make her mad enough to qualify, in the Anime, she has a habit of concocting selfish plots up to and including letting the rest of the Angel-tai drown rather than see her with her head stuck in a wooden cutout.
** Vanilla H is similar. She looks quite young, is a WaifProphet[=/=]OracularUrchin... and she'll give you three chances. Then she can destroy cities.
* ''{{Manga/Gangsta}}'''s Loretta Cristiano Amodio qualifies simply by already being the ''head'' of [[TheMafia The Cristiano Family]] at the age of 14, but then you find out she's not only packing heat but knows how to use it too.
* ''Manga/{{Gunnm}}'':
** Sechs was born/created less than two years before kicking major arse all around Jeru.
** Elf and Zwolf appear more as comedy characters, but they're still pretty capable fighters, albeit outshadowed by the WorldOfBadass ZOT tournament. In the earlier stages of the manga they routinely slice up their opponents with RazorFloss, and apparently got Sech's arm this way before the main story. And they're no older than Sechs.
* From ''Manga/GunslingerGirl'', the eponymous {{cyb|org}}ernetic assassins, pre-teen children [[WeCanRebuildHim salvaged from near death]], trained and {{brainwashed}} to become Italy's most [[SuperSoldier elite]] counter-terrorism unit.
* Minnie May in ''Manga/GunsmithCats''. Bit of a subversion as well since she's [[OlderThanTheyLook also older than she looks]], and uses this to comical effect with her boyfriend, when, say, renting a hotel room. She's 17, looks about 13, and was originally a prostitute for paedophiles. After she met her boyfriend (a reputed underworld bomb maker), she picked up on his trade and is now something of a cute MadBomber.
* ''Anime/HellGirl'': Ai Enma, who takes on the form of a vulnerable young girl clad in either a kimono or a black and red fuku. When angered, she has the power to take out an entire village with powerful fire blasts. [[ReallySevenHundredYearsOld She's also far older than she looks.]]
* ''Manga/{{Hellsing}}'': [[FanNickname Girlycard]] has all of regular Alucard's powers in a funsized little-girl package. Why would an immortal, all-powerful shapeshifting vampire take on the form of a little girl? As far as the audience can tell, because [[ItAmusedMe it was amusing]].
** When Seras was younger, [[spoiler: seven years old in fact, after her parents were murdered and while her mother's corpse was being raped, she charged out of the closet that her mother had hid her in, picked up a fork, and stabbed him in the eye with it. She was then shot, but she survived.]]
** Integra fit this trope when she was younger. She shot her uncle in cold blood immediately after it was made clear that her new pet would do it for her, earning her more of said pet's difficult-to-gain respect. Additionally, Manga flashbacks reveal she was capable of ordering around full grown men like they were lapdogs.
* Argent, Iono's pint-sized, [[LittleMissSnarker smart-mouthed]], [[LadyOfWar samurai-like]], special forces bodyguard in ''Manga/IonoTheFanatics''.
* ''Manga/InuYasha'''s Kanna, despite being ten years old (technically, less than a year old), can absorb and deflect most of the characters' attacks very easily. Not only that, here's an attack you definitely cannot block-her sucking out your soul.
* Mizho in ''Manga/KarakuridoujiUltimo''. You think that her {{Goth}} image is just a tough act? Well, this girl has kicked three guys' asses using just pocky and a crutch. She is seen [[SlasherSmile smiling and laughing]] during all of this.
%% * ''Manga/KenichiTheMightiestDisciple'''s Miu Fuurinji was like that [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/c114/14.html when she]] [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/c114/15.html was only]] [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/c138/4.html six years old]].
%% ** Also Shigure Kousaka [[http://www.mangareader.net/337-23662-8/historys-strongest-disciple-kenichi/chapter-156.html as well]]
* Hatoko, five-year-old controller of Suzuka from ''Anime/KidouTenshiAngelicLayer''.
* One of the ''[[Anime/KirbyRightBackAtYa Kirby Anime]]'''s {{Ensemble Darkhorse}}s, Sirica, counts as one as well, being a young ActionGirl with a badass five-in-one weapon that can change into a flamethrower, grappling hook, bazooka, machine gun, and even a sword. Plus she's the daughter of the legendary Galaxy Soldier Garlude. And she's very cute, too. No wonder she's so popular despite only appearing in a few episodes.
* ''Franchise/LyricalNanoha'': In [[Anime/MagicalgirlLyricalNanoha the first season]], Nanoha and Fate are proficient magical combatants at age nine, joined by Hayate at the same age in the second, as well as the ReallySevenHundredYearsOld Vita. In the third season time has skipped ahead ten years, so Nanoha, Fate, and Hayate have grown up... but Vita hasn't (being immortal and thus [[NotAllowedToGrowUp no longer physically aging]]), and they have more to add to the mix, including Caro, a ten year old [[TheMedic medic]] who can summon [[{{Kaiju}} really]] [[PhysicalGod big]] [[InstantAwesomeJustAddDragons dragons]], and Vivio, [[spoiler: a clone of the legendary [[CrystalDragonJesus Sankt Kaiser]] whom Nanoha eventually adopts as her daughter]]. The fandom has been known to joke that any girl who cannot defeat a grown man by age 10 is disowned.
%% * The ghost girl Elizabeth from ''Anime/{{Maburaho}}''.
* Morgiana from ''Manga/MagiLabyrinthOfMagic'' seems fairly low-key at first, what with being a traumatised and much abused slave girl... Until you realize she belongs to the Fanalis, a {{Proud Warrior Race|Guy}} hunting tribe with borderline superhuman fighting ability, and she puts her skills to ''very'' good use once she's released from her owner and joins the main group. The opening shows her kicking the hell out of freaking tigers bigger than her... and the series reveal later that even a single scratch from these tigers would have killed her.
%% ** In Chapter 29 of ''Manga/MagicalRecordLyricalNanohaForce'', [[spoiler: Curren Huckebein]] also counted as this.
* ''Manga/MahouSenseiNegima'':
** The [[ReallySevenHundredYearsOld young-looking but centuries-old]] vampire/wizardess Evangeline A.K. [=McDowell=] was a mostly played-for-laughs villain in an earlier arc, but shows her badassery in the Kyoto and Tournament arcs - her earlier weakness was explained away as affection for the hero. A (much) later chapter has a character draw a humorous [[PowerLevels "Strength Table"]]. The Demon God sitting at the very top? Evangeline (with Chachamaru's help) took him down in a little over a minute [[[LargeHam and most of that minute was telling everyone around to make sure to watch her kill it]]].
** Yue Ayase commanded three of her Valkyrie classmates who were years her senior to aid her in knocking out a Griffin Dragon. The final attack on it was done, by Yue, dodging her ally's covering fire, with one magic attack and a dull ceremonial knife. And she gets more badass from there.
* ''Anime/MichikoToHatchin'': Hatchin evolves over the story into a more mundane than average version of this. At one point near the climax she faced off with a [[GangBangers former gang lord]]; throwing ''rocks'' at the guy with a high-powered handgun.
* Syal from ''Manga/MotherKeeper'' is this, looks like a sweet teenager and is extremely happy go lucky. She's actually the mother keeper that does most the work and is the best fighter on Eden's side.
* ''Manga/NabariNoOu'' has some examples:
** [[{{Tsundere}} Raimei,]] a 14-year-old samurai with a bad attitude and really badass samurai techniques.
** Shijima, the cute white-haired girl who managed to have the most powerful ninjas of Nabari's asses handed to them with just her hands. Also mopped the floor with all the main cast. Then again, [[spoiler: she is actually a Cat. Who is about 300 years old. And is also immortal.]] which should pretty much explain it.
* ''Manga/NaruTaru'' has to a degree, Mamiko Kuri.
* Miyabi in ''Manga/NininGaShinobuden''. She's the only regular who's even remotely competent.
* ''LightNovel/NogizakaHarukaNoHimitsu'''s Alice, a shy, sweet little maid [[spoiler:with a spiked bat, brass knuckles and enough strength to crack open a street and create a geyser]]
* ''Anime/{{Noir}}'''s Kirika. Quiet, sad, cute, and can kill in many creative ways. Taken to extremes when it's discovered that [[spoiler:she shot Mireille's parents, when she was a tiny tot in overalls.]]
* ''Manga/OmamoriHimari'''s Shizuku qualifies as one as well as being the only little girl of the series. She can track someone using the moisture in the air alone, spit icicles at high speed, and she's ''not'' being arrogant when she states that her water can cut through anything-she uses it like a freaking SWORD. Being able to turn to water to avoid the consequences of being sliced in half. And if she's at full power, she can trap you [[spoiler:inside a whirlpool-ON LAND.]]
** Then there's [[spoiler:Tama. Who, as part of her introduction chapter, pins the titular character to the ground and bites a chunk out of them. Said title character, Himari, can't even put up any resistance. Himari only lives because Tama thinks she tastes bad.]]
* ''Manga/OnePiece [[Anime/OnePieceFilmZ Film Z]]'' : [[spoiler: [[FountainOfYouth Getting transformed into a kid]] doesn't cause Nami to lose any of her BadassAdorable-ness.]]
* Mitsuki in ''Manga/{{Onidere}}'' looks like a cute grade-schooler who loves bears. But she is a member of the most feared gang in their area, the all-girl group Demon Head. She can also tame bears and get them to do what she wants.
* Alice the B-Rabbit (short for [[NamesToRunAwayFromReallyFast Bloodstained Black Rabbit]] from ''Manga/PandoraHearts'' could be the TropeCodifier for this: She's wearing one of the fanciest dresses on this list, smart and cunning (not to mention a distinct {{Tsundere}}), and parenthetically the [[OurMonstersAreDifferent most powerful chain]] there is. [[spoiler: Except she's not.]]
* Believe it or not, Misty from the ''Anime/{{Pokemon}}'' Original Series is 10 years old, the same age as Ash (although it's easy to miss because it's not stated in the dub).
* ''Anime/PokemonMewtwoReturns'': Team Rocket agent Domino. She has literally no Pokémon of her own, and manages to kick ass merely with gymnastics and electric ''flowers''. She also successfully fools the main cast into thinking she's one of the good guys by acting like a traditional dumb blonde when her real personality is exactly the opposite.
** Perhaps more badass than that is that Domino gets away with talking to ''Giovanni'' any way she damn well pleases, including telling him that he's crossed the line and lost all sense of PragmaticVillainy.
** All of the [[BadassAdorable female 'Dex Holders]] in ''Manga/PokemonSpecial'' qualify as this. Of note is Yellow, who everyone underestimates until she [[spoiler: [[BerserkButton gets pissed off]] and [[SuperweaponSurprise completely crushes the competition]]]].
** The Anime has at least two in Ash's Bayleef and Snivy. ''Best Wishes'' character Iris is this too...[[spoiler:but not for [[CrouchingMoronHiddenBadass the same reasons]] as in ''Pokémon White''.]]
** ''Manga/PhantomThiefPokemon7'' has Lily who is, [[spoiler:or was]], one of the best grunts Team Galactic has to offer (and in this continuity they're quite the fearsome bunch), but can't be older than fifteen at best.
* Homura Akemi from ''Anime/PuellaMagiMadokaMagica''. She never flinches, she never falters, [[spoiler: and until Madoka nearly makes a contract with Kyuubey,]] she never loses her cool. Killing witches in the utmost badass of manners. Her friends are no pushover either, and all of them are around 14 years old.
* ''Manga/RozenMaiden'' has a cast full of girly, childish magical dolls that are from the human perspective as good as invincible.
* Lady Kayura in ''Anime/RoninWarriors'', who, according to [[WordOfGod Sunrise]], is physically 12 years old. Doesn't change the fact she was the only foe the warriors could never beat.
* To a lesser degree, the preteen sorceress Lily in ''Anime/RuneSoldierLouie''.
* ''Manga/ShamanKing'' gives us Anna Kyoyama, an Itako (traditional Japanese shaman) and spirit medium who is Yoh's trainer and fiance. She's calm and mature for her young age, plus she kicks ass with her bead necklace, which she can also channel other spirits into others with. And to top it all off, she even tamed Hao's Shikigamis and used them as her own guardian spirits [[spoiler: until Hao turned them against her and the rest of the Yoh-gumi]]. Now that's saying something.
** And then there's Jeanne, [[spoiler:the real leader of the X-Laws]]. At first sight, she's just a twelve-years-old cutie... [[spoiler: whose furyoku levels are of the closest to Hao]].
* ''LightNovel/{{Slayers}}'': Lina Inverse is clever cynicism personified -- and people who [[ExpectingSomeoneTaller know her only by name]] are often shocked to learn that this short, big-eyed, [[ACupAngst small-chested]] teenager is the infamous Dragon-Spooker and Bandit-Slayer herself.
* Maka Albarne from ''Manga/SoulEater'' is a young, sweet and friendly girl ... who wields a ginormous scythe. Yup.
* ''LightNovel/SpiceAndWolf'''s Holo is quite the tease, but [[ReallySevenHundredYearsOld has lived for centuries]] and could turn into a big bad wolf to maul anyone who tries to attack her or Lawrence.
* Rio in ''Manga/{{Spiral}}''. She lures a teacher to his death, blows up her own chest to hide the evidence, built the bomb that did it.
* In ''Anime/TigerAndBunny'' [[spoiler:Kaede Kaburagi]] ends up becoming Sternbild's most badass little girl after developing superpowers. [[spoiler:What other ten-year-old can claim to have saved almost every Sternbild superhero from a MadScientist's inescapable death trap?]]
* ''Manga/ToLoveRu'': Don't. Mess. With. The. Loli.... or her friends
* ''LightNovel/TrinityBlood'''s Seth is both powerful and sneaky. And it turns out [[spoiler:she's waiting to correct the weakness against the UV and silver from her "Children" to make perfect soldiers who would conquer the Outer world. She never stopped her plans from world conquest]].
* Rebecca Hopkins of ''Anime/YuGiOh'' is twelve years old, in college, the American dueling champion and manages to hack into [=KaibaCorp=] to guide Seto and Yami Yuugi through while under attack from Dartz.

[[folder:Comic Books]]
* ''Comicbook/TheAuthority'': Jenny Quantum exemplifies this. Her superhero career started a few days after she was born, when she vapourised a giant's legs; nowadays, a nine-year-old physically aged to 14, she's the [[AChildShallLeadThem leader of the team]]. (It probably helps that she's the resurrection, or [[Series/DoctorWho regeneration]], of previous leader Jenny Sparks.)
* ''ComicBook/{{Batgirl|2000}}''. Although now a teenager, Cassandra Cain was revealed to have finished the majority of her assassination training at the age of eight. I say most because she semi-failed her last test (she killed the guy but was so horrified by what she did that she ran away from David Cain, her father/mentor.) A FanNickname for Cassandra is "Little Miss Ninja Goddess".
* ''ComicBook/BodyBags'': Panda Delgado is a petite although buxom 14 (and a half) year-old - and a professional bounty hunter with a deadeye aim.
* In ''Comicbook/{{Supergirl}}''/''Comicbook/{{Batgirl}}'' story ''ComicBook/ElseworldsFinestSupergirlAndBatgirl'', Barbara Gordon saved the Wayne family's lives when she was a little girl. After Joe Chill murdered her parents she picked her dad's gun, aimed at the man who had just slaughtered her family and ordered him freeze.
* ''Comicbook/KickAss'': Hit-Girl is an 11 year-old girl with a lock for a symbol and a katana, who annihilates a room full of baddies in her first appearance.
* ''{{ComicBook/Livewires}}'': The Creator/MarvelComics MiniSeries included Gothic Lolita, the team's android muscle, who looked young and dressed in her [[ElegantGothicLolita namesake style of clothing]].
* ''ComicBook/{{Runaways}}'' from Marvel Comics: Molly Hayes is the eleven-year old physical powerhouse of her team and falls somewhere between this trope and BadassAdorable, DependingOnTheWriter. It's thus uncertain how much of the little kid persona we see is veil and how much is her real personality.
* ''Comicbook/SinCity'': Miho. [[Creator/FrankMiller Deadly little Miho]].
* ''Comicbook/XFactor'': Layla Miller, as written by Peter David. Don't mess with her: ''[[CatchPhrase she]] [[ConfusionFu knows stuff]].''
* ''ComicBook/XMen'':
** [[ComicBook/KittyPryde Shadowcat]] was a master ninja (and experienced superhero and expert hacker) by the age of 14, thanks in part to some YearInsideHourOutside training by Comicbook/{{Wolverine}}'s EvilMentor.
** Comicbook/{{X 23}}. Although now a teenager, when she was being trained to be the killing machine she currently is, she used her cute little kid-ness to get close to her targets and eliminate them. Her first kill was at age 9, and it's implied that by the time she escaped her handlers at 13, she already amassed a body count in the ''hundreds''.
** [[ComicBook/IllyanaRasputin Magik]] was the most sexualized of the female ComicBook/NewMutants. She has never been seen pursuing a romance, but would wear the skimpiest outfits and a few times flirted with bad guys while threatening them with eternal torment. Her antics are mild by today's standards (well, except for the dental floss she'd wear as the Darkchylde), but it still becomes a little awkward considering her true age.
* Amy Rose from ''ComicBook/ArchieComicsSonicTheHedgehog''. Went from being a BrattyHalfPint to HUMILIATING the Iron King, a MadeOfIron bruiser of a warlord who had previously proved impervious to Sonic's high speed attacks, in each of their encounters and flattening a massive war machine in one hit.
* Lian Harper in ''ComicBook/TeenTitans'' had the makings of this, considering her dad's a superhero, her mom's a supervillain, and she has lots of surrogate uncles and aunts in the superhero community. When she's being held captive by Vandal Savage, ComicBook/BlackCanary tells her to show Vandal "The finger trick Auntie Dinah taught her." Lian then broke Vandal's thumb. She was ''three'' at the time.
* Gertrude from ''ComicBook/IHateFairyland'' might be a subversion. While she looks 6 and can beat the living fluff out of anyone who has the gall to get in her way, she's really in her thirties when she's doing all that.
* Inverted in ''ComicBook/TheTransformersMoreThanMeetsTheEye'': the excitable, impulsive, and remarkably badass Whirl is one of the tallest characters on the crew, but his ''human avatar'' turns out to be a cute, pig-tailed pre-teen girl -- outfitted with dual semis and an eyepatch, of course.
* ''ComicBook/BlackMoonChronicles'': Pepette has a moment where she goes up to an UpperClassTwit holding flowers... and rips a knife out of them, holding it to his throat.
* Late in ''ComicBook/{{Revival}}'' the character Atlee is introduced. She's a tween ninja who racks up at least a half-dozen confirmed kills in a single scene.
* According to ''ComicBook/RedSonja'': ''Sanctuary'', her career in sword-swinging and ass-kicking began when she was only twelve years old as an enforcer to a goddess.

[[folder:Comic Strips]]
* Susie Derkins from ''ComicStrip/CalvinAndHobbes'' is implied to play lacrosse and routinely beats Calvin senseless whenever he hits her with a snowball/water balloon.

[[folder:Fan Works]]
* ''Fanfic/TheMadScientistWars'', we have two-year old Maxwell Eta, the youngest member of the [[BadassFamily Tinker Clan]]. Technically a badass ''Shota'', but seeing as how an attempt to enroll him in Preschool ended in him staging a ''successful'' rebellion, complete with forcing the Superintendent to sign a loyalty oath... he ''has'' to count.
%% * Ashley [=McFly=]/Leather Ashes from ''FanFic/PrettyCurePerfumePreppy'' isn't really innocent, but all in all badass, most notably in the end of episode 24: to put it shortly, a drug dealer shows up and tries raping her, only to have her ''stab him in the heart''.
%% -->'''Ashley:''' Listen up, dude, I am not like the other schoolgirls. See ya in the next life.
* A ''lot'' of ''Series/BuffyTheVampireSlayer'' fanfic has focused on the ten-year-old baseball-playing "Littlest Slayer" shown in the series last episode, during the "activation" of every potential slayer on the planet.
* While we haven't ''seen'' much of her ability "on panel," Lian Harper of ''Roleplay/DCNation'' (who is VERY much alive in their timeline, thankyoumuch) is definitely shaping up here. Raised by [[BadassNormal The Arrow Family]] and [[ComicBook/TeenTitans a cadre of superpowered "uncles" and "aunts"]]...while also being trained in secret by Shiva Wu-San? That's one scary 12-year-old.
* 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.
* [[Manga/CardcaptorSakura Tomoyo Daidouji]] gets this treatment in the later chapters Shadow Crystal Mage's epic crossover fic [[http://www.fanfiction.net/s/6095074/10/Takamachi_Nanoha_of_2814 Takamachi Nanoha of 2814.]] It boggles the mind, doesn't it?
* FanFic/ToyHammer has Emma. She's little, she's a miss, and she's certainly badass as she [[spoiler: is fated to become the God Emperor of Mankind.]]
* In the ''Manga/BlackLagoon'' fic [[http://www.fanfiction.net/s/5924482/1/Four_Pirates_and_a_Little_Lady "Four Pirates and a...Little Lady?"]] Revy's 13-year-old sister Rachel easily qualifies. [[spoiler: At one point she's fighting a North Korean special-forces type, and holding her own for a while.]] Of course, growing up in a very tough slum tends to lead to this sort of thing.
* Medley is the youngest flier among the seven main heroines of ''Fanfic/AceCombatTheEquestrianWar'', but underestimating her is a surefire way to get hurt.
* Adelle is an experienced combatant in ''FanFic/TheTaintedGrimoire''.
* In the ''Literature/{{Discworld}}'' fanfic of Creator/AAPessimal, the Rimwards Howondalandian Assassin Johanna Smith-Rhodes is first introduced as a child living with her family on the Howondalandian veldt. Living near the border with the ancestral Zulu enemy, her family farm is attacked by Zulus raiding over the border into White Howondaland. (an expy of Afrikaaner South Africa). Two Zulus make the fatal mistake of underestimating the eleven-year old girl who appears to be holding a machete which is too heavy for her. At age nineteen, she leads a reciprocal raid into the Zulu country and delivers ''Inhumation With Severely Extreme Prejudice'' to a warlord's kraal. This brings her to Assassins' Guild notice. Among other responsibilities, she now counsels student Assassins who have killed before the age of eleven. [[http://www.fanfiction.net/s/5423228/15/Murder-Most-Orrible Murder Most 'Orrible]] and [[http://www.fanfiction.net/s/5055274/4/The-Graduation-Class The Graduation Class]]
** Students at the Assassins' Guild School are not to be discounted either. In the right circumstances, thirteen-year old schoolgirls with weapons training and a reason to use it practically can be ''lethal''. See ''[[https://www.fanfiction.net/s/11536013/1/Hyperemesis-gravidarum Hyperemesis Gravidarum]] for the way Mariella Smith-Rhodes (same family) and [[BadassIsraeli Rivka ben-Divorah]] (who on our world might get a job offer from Mossad) put their training into practice. [[note]]Rivka, according to WordOfGod, is explicitly based on Nathalie Portman's character Mathilde[[/note]]
* FanFic/MarissaPicard first took command of the ''U.S.S. Enterprise'' when she was 10 or 11 years old, and by the time she was 14 she was in command of ''all of Star Fleet''. She's also got the highest Kobayashi Maru time ''evar'', so don't mess with her.
* In ''FanFic/CrownsOfTheKingdom'', Annelise, one of the children from the It's a Small World ride, is said to have killer aim when throwing her wooden clogs, something she was preparing to prove to a horde of Dispirations right before the cavalry arrived.
* The MoeAnthropomorphism of the Enterprise (CV-6) from ''Fanfic/PacificWorldWarIIUsNavyShipgirls'' is...a 12-17 year-old looking girl. Who knew?
** Also applies (to a degree) with Nevada (BB-36), who is around the same height as the former, but is incredibly skilled at target shooting.
* In ''FanFic/ZeldasHonor'', Saria is fairly timid in the commotion of battle during Acts 1 and 2, but by the end of Act 3, she can hold her own against [[spoiler: Josclyn]] in mid-air while trying to save [[spoiler: Giana]] from almost certain death; she also convinced [[spoiler: the dragon, Qargus]], to help Link and the others and then appearing to save the day on a [[spoiler: dragon herself]]; Saria also coming in to distract the [[spoiler: Hunger demon]] while [[spoiler: Navi revives Link]] and surviving for quite a while is also another example.
* ''Fanfic/{{Wonderful}}'': Missy "Vista" Biron is thirteen. She's a super-hero capable of distorting space. In episode 13, she uses her power to avert cannonballs.
-->The tank fired the next shot, and Vista made space curl. The shell did a loop in the air, before coming back down upon the tank. It managed to dodge out of the way, but the ensuing explosion made the tank tumble over.\\
"Have I mentioned that you are TERRIFYING when you get angry?" Clock idly commented, and Vista just grinned.
* Cynthia in ''Fanfic/PokemonResetBloodlines'', at age ten raided [[TempleOfDoom tombs]] [[TreasureHunter looking for treasures]] and was able to beat the tar out of older kids trying to bully her.


[[folder:Films -- Animation]]
* ''WesternAnimation/{{Hoodwinked}}'' has Red Puckett, who impressively has a black belt in karate and beats up the Wolf.
* ''WesternAnimation/TheIncredibles'': Nice turnaround for Violet.
* Winnie from ''WesternAnimation/TheBoxtrolls''.

[[folder:Films -- Live-Action]]
* Film/BuffyTheVampireSlayer would have been all of fourteen years old in the film, fifteen or sixteen at the start of the series, and the shortest member of the cast. She was 17 or 18 in the film; the series retconned her age.
* Subverted in ''Film/BallsOfFury'' when a greatly feared ping pong champion turns out to be a cute little Chinese schoolgirl, but the hero easily crushes her and laughs in her face, causing her to cry.
* ''Film/BattleRoyale'': Some of the more capable girls become this by necessity. Most notably, Mitsuko Souma and Takako Chigusa.
* ''Film/{{Chocolate}}'': Zen, an autistic teenage girl who is [[TheRainman martial arts savant]].
* The pre-time skip version of Cataleya in ''Film/{{Colombiana}}''. And this was BEFORE she learned how to kill people.
* ''Literature/{{Dune}}'': Alia. Even more so in the novel. While the [[Film/{{Dune}} David Lynch film]] either glosses over it or fails to explain it, in the scene from the movie after she [[spoiler:kills Baron Harkonnen]], where she's out on the battlefield with the crysknife and the strangely gleeful look on her face, she is actually engaged in [[spoiler:systematically killing the enemy wounded.]]
* ''Franchise/FridayThe13th'':
** ''[[Film/FridayThe13thPartVIITheNewBlood Part VII: The New Blood]]'': Tina Shepard, who uses PsychicPowers to smash, electrocute, hang, and immolate Jason (amongst other things), which came to a head when she blew her own house up to try and kill him.
** ''[[Film/FridayThe13thPartVIIIJasonTakesManhattan Part VIII: Jason Takes Manhattan]]'': Rennie, who stabs Jason in the eye the first time he attacks her (which is actually quite impressive by the standards of Jason's victims) and melts his face with toxic sludge.
* ''Film/FullMetalJacket'': [[spoiler: The V.C. sniper]]
* Roxy in ''Film/GodBlessAmerica''.
* The title character of ''Film/{{Hanna}}''.
* ''Film/HardCandy'': Haley Stark (Creator/EllenPage) kicks major pedophile ass.
* In ''Film/KickAss'', Hit-Girl takes this to the absolute extreme, even more so than her comic incarnation. The apartment scene alone makes her worthy of this, but she also gets major points for the DarkenedBuildingShootout and the ExecutiveSuiteFight. She [[ClusterFBomb swears more]] and kills more people than all of the other characters combined, and is easily the [[EnsembleDarkhorse most popular character]] in the film. She also gave the MoralGuardians a heart attack.
* ''Film/KillBill'':
** Gogo Yubari. A cute Japanese girl who wears a girly school uniform. But she's also deadly as hell. And she can do wonders with her weapon of choice -- a spiky sphere on chain.
** O-Ren Ishii, when she was young. She manages to avenge her parents when she's a pre-teen and she quickly becomes one of the top female assassin in the world.
* ''Film/TheLastBoyScout'': The daughter of Creator/BruceWillis' character, who rescued her dad by pretending to be a lost little girl and approaching a gang of cutthroat corporate mercenaries and hands her father a .357 hidden in her teddy bear.
* ''Film/LittleSweetheart'' gives us Thelma. Sure, she can't aim very well, but she will chase you and she will kill you if she's trying to. To make up for this, she has the stealth skills of a ninja (after the first stealth attempt, which failed), the empathy of [[VideoGame/{{Prototype}} Alex Mercer at the start of Prototype]], the photography skills of [[VideoGame/DeadRising Frank West]] and the manipulation skills of an early-on [[Manga/DeathNote Light Yagami]].
* ''Franchise/ANightmareOnElmStreet'':
** Alice in ''[[Film/ANightmareOnElmstreet4TheDreamMaster The Dream Master]]'', who literally did kung fu on Freddy.
** ''Film/FreddyVsJason'': Lori, (played by 5'1" Monica Keena) pulling Freddy out of the dream world, setting a dock on fire, and killing him with Jason's machete. By the end she is one of the most kickass {{Final Girl}}s in either series (the hottest).
* ''Film/TheProfessional'': Natalie Portman's character, Mathilda, although [[spoiler:she never actually goes through with anything.]]
* ''Film/{{Push}}'': Cassie Holmes (Creator/DakotaFanning).
* ''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.
* Robyn, from [[TheFilmOfTheBook the movie adaption]] of [[Literature/TheTomorrowSeries Tomorrow; When the War Began]] [[spoiler: takes out a group of soldiers in the climax and is shown carrying grenades at the end]]. Truthfully, it isn't really her choice.
* ''Film/TrueGrit'' (2010 version): Mattie Ross, not so much for being a killer (although she does [[spoiler: kill Tom Chaney]]) but for being utterly impossible to intimidate. Also [[DoYouWantToHaggle you do not want to haggle with her]]. The epilogue is a deconstruction of the trope, as it reveals that she's matured into a completely hard and joyless person.
* Kitty Pryde. In ''Film/XMenTheLastStand'', she made the Juggernaut her bitch!
* ''Film/{{Zombieland}}'': Little Rock (Creator/AbigailBreslin).
-->'''Tallahassee:''' You got taken hostage by a little girl?\\
'''Columbus:''' She was like a crouching tiger...\\
'''Tallahassee:''' She's twelve!
* In the 1982 film adaptation of ''{{Film/Annie|1982}}'', Annie is clearly more than a HeartwarmingOrphan. She's managed to stomp her evil caretaker's foot and make it hurt, outrun police officers, [[StuffedIntoATrashcan stuff boys into trashcans]], break her adopted father's leg (by accident while showing him what she's learned earlier) and [[spoiler:trick her kidnappers into pulling over, then steal their cheque, climb over a fence and rip it up in front of them]].
* The unnamed little girl on the flight in ''Film/RedEye''. Suppose you're a nine or so year old girl flying alone on a crowded flight, and you notice a man cornering a distressed-looking woman in the lavatory, and overhear him threatening her. You try telling the flight attendant, but she doesn't understand the situation and isn't much help. Then, as the flight lands, you see that woman stab the man that was threatening her in the neck with a pen and run like hell. The man chases her. Do you, a) sit there and do nothing, b) try to hide so he won't realize you're onto him, or c) kick your bag out into the aisle so he'll trip, giving the woman a little extra time? This girl picks c), and it probably gave Lisa enough of a headstart to save her life. The fact that she managed to do this without ''anyone'' noticing is doubly impressive.
* Roxy from ''Film/KingsmanTheSecretService''. She's the tiniest of the Kingsmen candidates, but proves herself more than capable of handling any given situation.
* ''Film/{{Logan}}'': Laura/X-23 is a TykeBomb ScreamingWarrior who has a comparable kill count in the movie to ''Wolverine'', despite being eleven years old. While all the experimental children were trained to fight, Laura is by far the most dangerous of them all. {{Subverted}}, however, in that RealityEnsues: Despite her skill she's ''still'' just a child, and she gets in trouble when she doesn't have room to maneuver, loses the element of surprise, or is simply weighed down by numbers. And when an opponent ''does'' get a hit in, she goes down hard.

* Arguably, all the female cast in ''Literature/{{Gone}}'', but especially Brianna, the youngest ActionGirl of the series.
* Astra in ''Literature/WearingTheCape'': A FlyingBrick, Hope/Astra wears armor and carries a 100lb titanium maul, partly to raise her game, but mostly because without it she doesn't look threatening ''at all''.
* 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.
* Virra from ''Literature/LoyalEnemies'' is a seven-year-old half-elf girl. She is, however, a great archer, a KnifeNut in training and a member of [[spoiler:an elven clan gifted with the killing touch]]. She manages to take out a skilled, much, much older elven master wizard, dozens of vicious bird-reptile monsters and a barely visible giant werewolf-bear hybrid, all while looking and behaving like a sweet child.
* ''Literature/{{Dragaera}}'': Thou shalt not mess with Devera. Seriously. Sure, she looks about eight, but she once ''[[DidYouJustPunchOutCthulhu ate a Jenoine]]''. Admittedly, she was a dragon at the time, a form in which she's unlikely to be underestimated, but still.
* Rachel from the ''Literature/SwordOfTruth'' novels becomes quite the badass by the end of the series. Trained by the BadassNormal of the series, it's hard to see how she couldn't be. By the eighth book, most specifically. Nothing quite like [[spoiler:confusing the hell out of the captive wizard by waving with a happy little grin when you're posing as someone under threat of death if he doesn't cooperate. Oh, and that soldier standing behind you? Yeah, that's your BadassNormal adoptive father, so flip him a few knives for him to fight with... from UNDER YOUR SKIRT.]]
* Although she's not a prominent character, a girl named Kym in ''Literature/ReturnOfTheEmperor'' 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.
* 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.
* It's glossed over, as it happened about eight years before the book actually starts, but the protagonist of ''Literature/{{Graceling}}'' once killed her perverted distant cousin ''with one blow. When she was eight''.
* Creator/NealStephenson's [[PostCyberpunk post-cyberpunk]] novel ''Literature/TheDiamondAge'':
** One of the many convoluted subplots revolves around a [[TheTriadsAndTheTongs Shanghai crime boss]] whose suspected child trafficking activities turn out to be actually a large-scale plan to save unwanted baby girls from certain death and provide them with an education only high-class children can dream of. Through clever planning he also gets his hands on a mass-produced version of an electronic GreatBigBookOfEverything, that was supposed to be a unique item for the granddaughter of the [[{{Fiction500}} richest man on earth]]. Being Chinese, they also were all trained in [[WaifFu martial arts]]. In the end, it all comes down to Shanghai going to hell with a large scale civil war with ethnic cleansing, suicide bombings, and all the other ugly things. But then [[spoiler:the day is saved by massive armies of twelve year old girls marching in huge columns from the countryside and putting down all resistance in a matter of hours.]]
** Nell. [[spoiler:She received the original of the GreatBigBookOfEverything, and the engineer who made it -- and was later blackmailed into providing the many given to the trafficked girls -- altered the plans for those copies to make them subservient to the original...so when Nell shows up, she immediately has a fanatically-loyal army of badass gangster-killing twelve-year-old girls at her absolute command.]]
* Likewise 12-year-old Hazel Meade (later Stone) in ''Literature/TheMoonIsAHarshMistress''.
* 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]].
* Arya Stark from ''Literature/ASongOfIceAndFire''. At the tender age of ten, she murdered a stableboy who got in her way. At twelve, she is training to become a member of an [[MurderInc assassin's guild]] that can change their identities/faces on a whim. She also has a psychic bond with a giant man-eating wolf.
* Tiffany Aching, in the Creator/TerryPratchett novel ''Discworld/TheWeeFreeMen''. Hell, she's nine years old, and takes on TheFairFolk with a FryingPanOfDoom!
* The heroine of "[[http://www.poemhunter.com/poem/adventures-of-isabel/ The Adventures of Isabel]]", a poem by Creator/OgdenNash is an unflappable little girl you don't want to get on the wrong side of, see her dealings with an enormous bear:
--> Isabel, Isabel didn't worry
--> Isabel didn't scream or scurry.
--> She washed her hands and straightened her hair up
--> Then Isabel quietly ate the bear up.
* ''Literature/HarryPotter''
** Hermione in the early books. More of a BlackMagicianGirl as she ages, but always TheSmartGuy of Harry's TrueCompanions.
** 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.
* Petra Arkanian from the ''[[Literature/EndersGame Enderverse]]''. The only girl of the group of kid space admirals that won the war, she went on to survive the global wars that followed the defeat of the buggers. In one scene, she is kidnapped by a special forces commando and calmly asks for the time to get dressed. When one member of the commando wants to hurry her, she calmly reminds them that her goodwill is worth more to his generals than his balls. In a bag. Now let me go to the bathroom before I go, please.
* Most of the female Meq in ''TheMeq'', 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/TheMillenniumTrilogy Lisbeth Salander]] ''is'' this trope.
* ''Literature/{{Firestarter}}'': Andrew [=McGee=] really ''tried'' to keep his daughter Charlie's pyrokinesis from getting out of hand, he really did. Unfortunately, they both fell into the hands of the GovernmentConspiracy which wanted to make a TykeBomb out of her... and when her father was killed by them, it wasn't long before [[BewareTheNiceOnes the running and screaming started]]. And then she got ''really'' nasty: she talked to the press.
* ''Literature/{{Redwall}}'': Mariel Gullwhacker. [[WaifFu Kicked the tail of a pirate king unarmed]], then beat up a seagull several times her size with nothing but [[WhipItGood a piece of knotted rope]].
* Kirsty from ''Literature/JohnnyMaxwellTrilogy''. She left the local karate club because no boy would dare to come near her.
* 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.]]
** The Hunters of Artemis are an entire militia of these, though they also fall into OlderThanTheyLook. Zoe Nightshade, for example, looks 14, but is at least two thousand years old. Artemis herself prefers to appear about twelve.
* 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.''
* Serroi, of Creator/JoClayton's ''Literature/{{The Duel of Sorcery|Trilogy}}'' and ''Dancer'' trilogies, is a MagicKnight who's been training as a soldier since she was thirteen. She's about four and a half feet tall, and [[OlderThanTheyLook at the age of twenty-seven to thirty, doesn't have to put much effort into passing for twelve]].
* In ''Literature/TheWitchesOfKarres'', the two youngest witches, Goth and The Leewit, are two cute little girls, ages ten and seven. Little Goth can make your gun explode in your hand and pick your pocket from across the room. Little Leewit will burst your eardrums with an ultrasonic whistle and chew on your leg while you're distracted. It's a really ''bad'' idea to threaten them or their ParentalSubstitute.
* Nita Callahan (13-14 years old) and Dairine Callahan (11-12 years old) from the ''Literature/YoungWizards'' series. Carmela might count but she's a little too old, as well as being downright girly as well as tough.
** 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.]]
*** The blowing-up was awesome, too. Peridexis: "There is a high probability that the surrounding matter will react unfavorably." Nita: "Will our shield hold?" Peridexis: "...Yes." Nita: "Then let's start getting unfavorable!" Or something like that.
*** She even gets the spell named after her: "Callahan's Unfavorable Instigation." Even the name is pure awesomeness.
* From the ''Sisters Grimm'' series: Sabrina, the self-proclaimed "Queen of the Sneaks" and her sister Daphne.
* Several characters in ''Literature/TheWolvesOfWilloughbyChase'' series, but especially Dido Twite. Her half-sister Is takes over the badassery for a couple of books late in the series.
* Margo Smith of ''Literature/TimeScout'' begins her training slightly before she shows up on Time Terminal 86, but [[TookALevelInBadass takes a level]] when she shows up, and takes several more in the books that follow. All before she turns 18.
* 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.
* ''Franchise/{{Halo}}'':
** ''Literature/HaloTheFallOfReach'': The female Spartan-II trainees are all this, but in particular there's Kelly, who is always referred to in the general lore as being the fastest Spartan by far. At the age of seven, she not only outruns full grown Marines, but manages to knock one unconscious by side-arming a rock at his head. [[VideoGame/HaloReach Halsey's journal]] refers to an even earlier incident where Kelly disarmed a Master Sergeant of his clippers when he tried to cut her hair; it took three adults to subdue her.
** ''Literature/HaloGhostsOfOnyx'': Lucy-B091 was already a highly dangerous Spartan-III back when she was a 5'3" 12-year-old. Even as an adult, she's remarkably small, especially when you consider that most Spartans are around 7 feet tall.
** ''Literature/HaloTheColeProtocol'': As a child Spartan-II trainee, Adriana kicked the ass of several trained Marine guards during her and Jai's numerous escape attempts.
%% * Angel from ''Literature/MaximumRide''.
* Sorry from Creator/StevenErikson's ''Literature/MalazanBookOfTheFallen'' series exemplifies this trope. In the first book, she joins the most badass squad in [[EliteArmy the Bridgeburners]] while still in her teens and leaves a trail of blood in her wake on the way there. Her presence and uncanny competence when it comes to killing make ProfessionalKiller Kalam Mekhar queasy and the squad mage Quick Ben jump at shadows. Of course, she's also [[GrandTheftMe possessed]] by the Patron God of Assassins.
* Jasmine in ''Literature/DeltoraQuest''. When their group finds themselves caught up in the gladiatorial Rithmere games, it's not [[TheBigGuy Barda]] who wins, or [[TheHero Lief]], or even [[TheBerserker Glokk]]. It's her.
* 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.
* 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.
* The little Whistler girls of ''Literature/ABrothersPrice'', once they're above eight or so, all seem to be this. They were given [[ChildSoldiers soldier training]] to better protect themselves and their brothers while their elders are gone. When a shot rings out outside of the house, the littlest ones and the boys stream in first and their slightly older siblings follow "doing a slower rear guard, scanning over their shoulders for lost siblings or strangers." Teams of mixed-age little girls load and aim rifles. Twelve-year-old Blush directs the proceedings, though she does falter a little when someone actually knocks on the door. Heria, at fourteen, is more sure of herself.
* 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.
* Lessa of the ''Literature/DragonridersOfPern'' definitely counts. She survived a Hold-wide massacre at the age of 10, and went on to use her PsychicPowers to murder at least one, probably more, Stewards put in control of the Hold by Fax before she hit her teen years. Under her psychic control, the Hold's prosperity was systematically wrecked so Fax got no profit from his conquest. She succeeded so admirably that by the time she's pulled out of there ten years later, Ruatha Hold is a wasteland.
* Emily Roland, of the ''Literature/{{Temeraire}}'' series. When two bunyips (with several more waiting behind them) attack their group, she, a thirteen-year-old girl among grown men all running in fear, takes out her pistol, shoots the first in the thigh, reloads, and shoots it again in the head, ''all while staying perfectly calm and shaming the men for not helping her.''
* Lucy Pennykettle from [[Literature/{{Dragons}} The Last Dragon Chronicles]].
* 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.
* Skeeter Traps from ''Literature/ChroniclesOfMagic'' is a ten year-old girl whose father was gutted in front of her when she was eight. Since then, she joined the rebel faction and learned to kill grown men three times her size so that she'd never again have to stand by and watch "more good people" be murdered. She is also a Healer, able to wield Magic, and possesses a semi-disturbing infatuation with guns.
* 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.
* Ingrid, the main character of the ''Literature/EchoFallsMysteries'' series, is a middle school-aged girl who has single-handedly gotten herself out of such situations as being chased by the BigBad and being kidnapped, BoundAndGagged!
* Szelma of ''Literature/DoraWilkSeries'' is still in her teens and five-feet-nothing. She first threatens a head-taller vampire with a knife, then kills a not-so-small sea serpent.
* 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.
* 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.
* ''Literature/JourneyToChaos'': Zettai evaded Ceiha's secret police for an extended period of time before they caught her.
* 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]].
* 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.
* Vaness of ''Literature/TheWitchlands'' was one in her backstory. At the age of seven, she resolved one of the final battles of the war by bringing an entire mountain down on her opponents with her [[ExtraOreDinary power]].
* ''Literature/TheStormlightArchive'': Shallan Davar was like this as a child, to the point that at age eleven she [[spoiler:killed her mother when he mother tried to kill her]]. Deconstructed in that this event [[BrokenBird broke Shallan into a million pieces]]; she didn't speak for months afterwards, and spent years hiding inside herself, refusing to confront anything.


[[folder:Live-Action TV]]
* Out of all the characters in ''Series/RoundTheTwist'', the most physically dangerous is Linda, an idealistic 14-year-old environmentalist schoolgirl. As this is a non-action kids' show, this doesn't actually come up that often, however.
* Claire Bennet on ''Series/{{Heroes}}'' eventually becomes this, especially in the dark future.
* Alex on ''Series/WizardsOfWaverlyPlace'' is this, at least sometimes:
--> '''Alex:''' "By the way, we're having dragon heart for dinner."
** Max, after he's turned into a little girl and proceeds to kick Justin's ass in karate class.
* Jacky Faber, the heroine of ''Literature/BloodyJack'' By age 16 she is a Lieutenant in the Royal British Navy, a spy, a notorious pirate captain and has fought at two major battles of the Napoleonic wars. At Trafalgar for the British and at Jena for for the French.
* Dorothy Gale "Ace" [=McShane=], the [[{{Series/DoctorWho}} Seventh Doctor's]] companion. Sixteen years old when she comes aboard, whips up improvised explosives and incendiary devices in her spare time. Shot a Dalek in the face with a rocket launcher, clobbered another into non-functional status with a [[BatterUp baseball bat]], and took out Cybermen with gold coins and a slingshot. {{Deconstructed}}, especially in the Expanded Universe, as she came from a rotten home life, and her mental health was a bit of a mess.
* ''Series/{{Game of Thrones}}'':
** Arya Stark. "I'm good at killing fat boys. I like killing fat boys." And others. In the later seasons she becomes [[spoiler: a skilled assasin.]]
** Despite her age, Lady Lyanna Mormont proves to be just as fierce in person as her written words to Stannis indicated. This is a girl who can shame an entire room full of northern lords three times her size and age.
--> '''Davos:''' I suspect if [House Mormont soldiers] are as fearsome as their lady, the Boltons are doomed.
* Eleven from ''Series/{{Stranger Things}}''. She is only about 12-13 years old, but is capable of laying waste to squads of armed orderlies and schoolyard bullies alike.
* ''Series/NCISNewOrleans''' Laurel Pride is attacked while out for her run and quickly dispatches the guy with a few self-defense moves, likely taught to her by her father. At the end of the episode, she's attacked again and this time breaks a bottle across her attacker's hand, causing her to drop her gun and allowing her to flee.
* ''Series/{{NCIS}}'' When Emily Fornell is abducted, she manages to quickly rattle off a description of her abductor's van. After being rescued, she reveals that she left a tracking device on the guy, enabling the team to track him down.

* The Music/{{Gorillaz}} guitarist, Noodle, could [[http://www.youtube.com/watch?v=00gMyROPKj4 drop a 300-pound man]] at age ten.
* [[http://www.youtube.com/watch?v=uU6U-8LP1DY Juliet]].

[[folder:Pro Wrestling]]
* Kaicho Ramu started appearing in the ring at age six. She wears Music/IronMaiden T-shirts, can do the Chokeslam, 619, and Shining Wizard. Underestimate her, and she will demolish you, then pin you 1-2-3.
* Riho from ''Ice Ribbon'' debuted at age 8 and as of 2011 is 13. She busts moves like the running knee strike, [[Wrestling/EddieGuerrero triple suplex]], and the '''[[Wrestling/BryanDanielson CATTLE MUTILATION]]!!!'''
* Haruka took tosses and slams from the grown wrestlers in Wonder Ring Stardom at age nine, including making comebacks after being repeatedly tossed into the ring post.

[[folder:Tabletop Games]]
* ''TabletopGame/{{Mekton}}'' Isami Shinzato from the Virtual game. A BLIND thirteen-years-old girl who is one of the most dangerous HumongousMecha pilots, to the point that her name has become in-game jargon for a called shot to the cockpit in the opening moves of combat. She's also known to deal quite... [[GroinAttack harshly]]... with older male bullies.
* ''TabletopGame/VampireTheMasquerade'' A purchasable flaw. While this is a flaw in the game, note that flaws actually give you more points to spend elsewhere-- meaning a child vampire will actually be ahead of its companions wherever you put those points. There are several examples of powerful vampires that look like children, such as the Malkavian progenitor vampire looking like twelve little girls with glowing eyes.
* ''TabletopGame/{{Warhammer 40000}}'', age and power as a psyker are loosely related at best. Although, given 40K this is less Little Miss Badass and more [[BlessedWithSuck Little Miss Walking Portal to Hell]].
* In ''TabletopGame/D20Modern'', characters as young as 15 can be heroes. In D20 Apocalypse, heroes can be as young as 12. Meaning a 12 years old girl can dual wield guns, snipe opponents from a kilometer away, become a martial arts mistress, do ''Film/MadMax'' style vehicle stunts, scavenge old buildings for supplies, or many other things. Justified as kids have to grow up fast AfterTheEnd.
* In ''TabletopGame/LegendOfTheFiveRings'', Matsu Tsuko's first real combat experience occurred when the Phoenix Clan assassinated her father. She killed four of the Phoenix Clan's most skilled samurai with a wooden sword, at age twelve.

* ''Theatre/IntoTheWoods'': Little Red Riding Hood.

[[folder:Video Games]]
* ''VideoGame/ArTonelico2'': Cocona pushes this beyond the limits. She not only was a 11-year-old girl who used [[ImprobableWeaponUser her metamorphic hairbands(!)]] as her weapon of choice, alongside roundhouse kicks which are somehow capable of destroying doombots with such murderous efficiency that by the end of the game, your [[MagicFromTechnology wizard/cyborg/bards]] rarely get to cast their spells before all the enemies are already dead. Her supermove involves her shooting a giant laserblade out of her hair bands... [[RuleOfCool somehow]]. What makes her go above and beyond the call of being a Little Miss Badass, however, is that she does this while bodily protecting the reyvateil wizards/cyborgs/bards of the party, who are twice her age and body weight, [[spoiler: in spite of actually BEING a reyvateil herself, who is simply too young to manifest any real power.]] In a game filled with robot warriors, and highly trained knights with rocket lances with guns sticking out, the only listed reason for her badassery is that she is "a really energetic girl".
** Not only that, but due to certain events ([[spoiler:Midway through the game she has her Boundary Gate (the construct that keeps Reyvateils separated from their respective Song Server) broken through]]), [[spoiler:by the third game]] she's [[spoiler:BY FAR the most powerful Reyvateil alive due to having direct access to the combined power of all the Reyvateils connected to Infel Phira, surpassing even Frelia, Metafalss's resident Reyvateil Origin, known as a Goddess to most of the region's population, who was created to sing Metafalica, a piece of song magic that creates a FLOATING CONTINENT and requires H-wave flow rate and harmonics far far far beyond the limit of any single Reyvateil!]]
*** [[spoiler:And if that weren't enough, when Ayatane Kureha saw her singing METHOD_HYMME_GRANZERO=SPEAR/., he bailed and ran away within seconds; to put it in context, Kureha is one of the last surviving members of a warrior clan with the ability to see the future, who uses this power to predict and counter opponents' moves before they carry them out!]]
*** [[spoiler:Oh, and by the way, have a listen to [[https://www.youtube.com/watch?v=zPI9HUZjcb8 the song she sang in this event.]]]]
* ''VideoGame/ArcRiseFantasia'': Spunky and enthusiastic Cecille is a CuteBruiser, who can unleash a devastating amount of damage with her fists. [[spoiler: Is also technically [[OlderThanTheyLook Older Than She Looks]].]]
* ''VideoGame/BackyardSports'': Luanne doesn't run. She's so fast, it looks like she's teleporting. Oh, and she's four years old.
* ''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.
* ''{{VideoGame/Borderlands 2}}'': The most talented DemolitionsExpert on Pandora happens to be a ''[[CloudCuckooLander slightly]]'' [[AxCrazy unhinged]] 13-year-old girl named Tiny Tina.
* ''VideoGame/BunnyMustDie'': The protagonist Bunny, the [[AndNowForSomeoneCompletelyDifferent second protagonist]] Chelsea, two of the devils and even some of the {{Mooks}} qualify.
* The ''VideoGame/CapcomVsWhatever'' series. Creator/{{Capcom}} seems to be thinking along these lines since {{Ro|botMaid}}ll has a better track record than her brother ''VideoGame/{{Mega Man|Classic}}'' himself (Rock has only appeared once; Roll, at least ''twice''). Because of that, Roll can have the distinction (PowerCreepPowerSeep aside) of beating not only ComicBook/{{Onslaught}} and [[VideoGame/{{Okami}} Yami]], but also the ultimate badass of the ''Mega Man'' series!
* ''VideoGame/CastlevaniaRondoOfBlood'': Maria Renard, the secret playable character, definitely counts. Though it might just be the contrast that makes her shine. The actual hero of the game, Richter Belmont, controls with all the grace of a mack truck with a few flat tires. Maria can ''run'', double jump, attack super fast with an army of owls, and do a forward slide. It's a wonder anybody ever uses Richter in that game.
* Aurora from ''VideoGame/ChildOfLight'' is a very young princess who gets sent to a MagicalLand filled with monsters. She destroys said monsters with a huge sword and light magic.
* ''VideoGame/ChronoCross'': Marcy. Leah's more a CuteBruiser sort, but Marcy is more than happy to tell you her opinion of you as she's beating you down. Becomes playable later, too.
* The ''VideoGame/{{Darkstalkers}}'' series. Bulleta/Baby Bonnie Hood. She's a [[HeWhoFightsMonsters monster-hunting]] BadassNormal, being the only one who shows no supernatural or high-tech abilities, just heavy munitions. Yet, she takes down Darkstalkers who are far bigger and stronger than her regularly.
** To put it in perspective, a low-level Darkstalker can destroy an entire (human) army and could scare the literal crap out of a hardened veteran marine. Bulleta makes Class-S Darkstalkers shit their pants (Class-S being the strongest level).
* ''VideoGame/{{Disgaea|HourOfDarkness}}'': Etna who, at one point, reverses a BatmanGambit back onto her blackmailer and ends up kicking his ass from here to next Friday. Though she is [[ReallySevenHundredYearsOld Really Fourteen Hundred Seventy Years Old]], she's around 13-14 by demon standards.
** In the second game there's Adell's nine-year-old sister Hanako.
** [[BadAssBookworm Raspberyl]] in the third game.
** And in the [[VideoGame/Disgaea4APromiseUnforgotten fourth]] there's Fuka Kazamatsuri, a fourteen-year-old OrdinaryHighSchoolStudent who beats powerful demons and {{Living Weapon}}s into submission with a baseball bat. Desco is even younger and cuter, but just as badass (though not ordinary like Fuka, being an artificial demon).
** And Marona (and even more her alternate-dimension clone Carona) from the spin-off VideoGame/PhantomBrave.
** And of course there are most of the female [[PlayerMooks generic units]].
* ''VideoGame/{{Drakengard}}'' has a six-year old Manah with evil magic powers as the leader of TheEmpire, and the game even calls her "the source of all evil."
* Babette from ''VideoGame/TheElderScrollsVSkyrim'' is a 300+ year old vampire assassin with the body of a 10 year old girl. Also a master of alchemy, and [[spoiler:one of two Dark Brotherhood members (besides the player) to survive the hideout being swarmed by soldiers and then exploding.]]
* ''VideoGame/EnchantedArms'': Yuki. One of the youngest people depicted in the game, and easily on par with an experienced knight in combat prowess.
* ''VideoGame/EvilZone'' the anime-inspired fighting game, the arguably second-most powerful character is Kakurine, a 40,000-year-old sorceress/priestess/goddess who looks like she's about 8, can teleport at will, enjoys playing with hoops made from pure destructive energy, and giggles cutely as she throws armored warriors and huge mercenaries about with ease. However, she's a goddess who simply chose the form as pure amusement.
* Lily Flyer from ''VideoGame/FZero GX''.
* The ''Franchise/FinalFantasy'' series. Most of the games have a "Little Girl" archetype, that is, an immature or young female character.
** ''VideoGame/FinalFantasyIV'': Porom is only 5, but she can learn every single White Magic in the game. There's also Rydia, who gets a PlotRelevantAgeUp in the middle of the game, but before that she ''definitely'' counts!!
** ''VideoGame/FinalFantasyVI'': Relm has the highest natural Magic Power in the game. She surpasses even Terra, who is half-Esper and thus practically a demi-God who has been able to cast magic all her life.
** ''VideoGame/FinalFantasyV'': Krile. The Earth Crystal room's scene is what puts her ahead of all the others by far, personally.
** ''VideoGame/FinalFantasyVII'': Yuffie, who manages to steal the entire party's Materia, and continuously escape from them. When they finally catch her, she tricks them and escapes from them again.
** ''VideoGame/FinalFantasyIX'': Eiko. Yes, she's six years old and adorable, but don't piss her off, or she will summon a giant monster that will annihilate you.
** ''VideoGame/FinalFantasyX'': Rikku is just a happy 15 years old girl, who can punch you with her gloves, steal your stuff and use her turbo which is perhaps the third most powerful one.
* ''[[VideoGame/FireEmblemTellius Fire Emblem: Radiant Dawn]]'': Empress Sanaki.
** Don't forget Nino, Fir, Myrrh, Fa, Mist (by some accounts), Shanna, Sophia, and Amelia. Also a few Badass Shotas: Rolf, Lugh, Lleu, Tormod (by some accounts), Ross, and Ewan.
** In ''VideoGame/FireEmblemAwakening'', Nowi ''seems'' to be the deal... save for being an over [[ReallySevenHundredYearsOld 1,000-year-old]] [[OurDragonsAreDifferent manakete]]. Her daughter Nah is more of the real deal, and so is a well-raised female!Morgan. Ricken, Donnel, and a male!Morgan qualify as male examples.
** In ''VideoGame/FireEmblemFates'', the well-raised Mozu (an {{expy}} of Donnel), Elise and Sakura can become this when promoted, and the same goes to [[RareMaleExample Hayato]] (an {{expy}} of Ricken); on the other hand, Nyx ''looks'' like an example of the trope but is [[OlderThanTheyLook actually an adult woman]] whose growth was stunted due to a curse cast on her [[spoiler: as punishment for having been an EnfanteTerrible version of this trope]]. The [[spoiler: second generation]] has Kana (of either gender), Kiragi (RareMaleExample) and Midori.
* ''VideoGame/GoldenSunDarkDawn'' has Princess Himi of Yamatai, a noble {{miko}} specifically noted to be only a little older than the little kid [=NPCs=] running around town. She also practices ninjitsu and dark magics via [[ClassAndLevelSystem class changes]], and even as a holy priestess can sicc dragons on the enemy. She has [[TheyWastedAPerfectlyGoodCharacter very little on-screen]] CharacterDevelopment, but she's otherwise pretty capable of messing up anything that messes with her.
* ''VideoGame/GrandChase'': The female cast. That being Elisis, Lire, Arme, and Amy.
* ''VideoGame/GuiltyGear'': The [[SugarWiki/NeedsMoreLove under-appreciated]] nurse-loli Fanny from that one iteration that nobody ever played.
* ''VideoGame/HitmanAbsolution'' has the genetically engineered Agent-in-the-making Veronica, whom Agent 47 spends most of the game trying to safeguard/rescue from The Agency. Alluded to throughout the game, and finally shown when late in the game she suddenly kills a group of Dexter's soldiers in an impressive display of deadly reflexes.
* ''[[http://www.ninjakiwi.com/Games/Action/Play/Guns-n-Angel.html Guns N Angel]]'' a Flash game. The protagonist who is apparently an expert with assault weapons and explosives.
* ''VideoGame/KnightsOfTheOldRepublic'': Mission Vao is fourteen years old, and BadassNormal. Yes, she has the lowest HP in your party. Yes, she's a sweet young lady higher on the KarmaMeter than the party's Jedi. [[spoiler: Yes, if you go to TheDarkSide, you have to kill her]], but she is a skill monster with a nasty sneak attack. Furthermore, she ''survived on her own'' in one of the worst slums in the known galaxy, despite being of a race, gender, age, and attractiveness level (young, pretty, Rutian Twi'lek female) that would have normally pigeonholed her into prostitution and/or slavery. It was several months ''after'' Griff abandoned her that she fell in with [[TheBigGuy Zaalbar]]. Given that, her BerserkButton over being called or treated like a helpless kid is kinda understandable.
* Ellie is this in ''VideoGame/TheLastOfUs''. She shows her true colors near the end of the game after [[spoiler: Joel gets impaled by an iron bar in the university, requiring her to protect him for the next couple months instead]].
* ''Franchise/TheLegendOfZelda'':
** ''VideoGame/TheLegendOfZeldaTheWindWaker'': Young pirate captain Tetra [[spoiler:aka Zelda]].
** ''VideoGame/TheLegendOfZeldaSpiritTracks'': And [[spoiler:Tetra's granddaughter,]] Zelda. Don't mess with her in her phantom armor...or when she has a bow in her hands.
** In ''VideoGame/HyruleWarriors'', [[VideoGame/TheLegendofZeldaTwilightPrincess Agitha]] is only 10 years old but is still just as capable as any of the other playable characters when it comes to killing ridiculous numbers of enemies.
* Miyako Arima from ''VideoGame/MeltyBlood'' is just the younger cousin of the main character, and a completely normal human who relies only in fighting skills. However, anyone that can take on [[PhysicalGod Arcueid]], [[NighInvulnerability Ciel]] or [[EldritchAbomination Nrvnqsr Chaos]] '''certainly counts'''.
* Sunny in ''VideoGame/MetalGearSolid4GunsofThePatriots'' and again in ''VideoGame/MetalGearRising''.
* ''VideoGame/{{Onechanbara}}'': Saki. She wields a {{katana|sAreJustBetter}}, can withstand kicks from [[SuperStrength super strong]] [[ArtificialHuman cyborgs]], jump off buildings, destroy pavements, cut a truck in half among other things with little effort.
* Maeve from ''VideoGame/{{Paladins}}'' is a young, small thief who cuts foes to ribbons with her daggers and cat-like agility. While she can't take much of a hit, she is incredibly fast, agile and can blind enemies with [[CastingAShadow magical darkness]].
* Every female playable character in ''Franchise/{{Pokemon}}'', and a few [=NPCs=]. Regarding the latter, [[spoiler:Iris]] from ''VideoGame/PokemonBlackAndWhite2'' is the crowning example, as [[spoiler: she has become Champion of all of Unova]].
* ''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 [[CrowningMomentOfHeartwarming oddly sweet moments]] with the game's resident MrFanservice BloodKnight.
* ''Franchise/ShinMegamiTensei'' has Alice. Nice girl who loves dolls? Sure. [[DarkMagicalGirl Insane sorceress]] capable of casting the deadliest [[CastingAShadow Dark-aligned]] [[OneHitKill One-Hit KO]] attack and who charmed two Goetia demons into serving as her guardians by sheer force of cute? That too.
* ''VideoGame/StarOceanTheLastHope'': Meracle Chamlotte doesn't seem all that badass at first glance, being a {{Stripperiffic}} {{Moe}} {{Catgirl}}, but once you max out her Critical skill and get her some decent equipment her multi-hit killer moves become absurdly deadly; she can clear the field with a single [[DeathOfAThousandCuts Claws of Fury]] that scores something on the order of a dozen consecutive critical hits. Needless to say, [[HolyShitQuotient jaws were dropped]].
** Lymle Lemuri Phi, the MagicalGirl of the game, first appears as just another spellcaster. But one can clear the entire field of enemies with a few well placed spells if they use her right.
* ''VideoGame/SuperRobotWars'': Latooni Subota, whose calm, analytical approach to combat makes her a deadly opponent, even when she's wearing a [[ElegantGothicLolita frilly dress]]. And that goes double for her HumongousMecha.
** Canonically, when she does her combo attack with Shine, Latooni is piloting both mecha simultaneously while having Shine's precognitive sixth sense beamed into her brain by the WiNK3 system.
* ''VideoGame/TalesSeries'':
** ''VideoGame/TalesOfPhantasia'': Suzu Fujibayashi is a eleven-year-old {{Ninja}} girl with some fabulous fighting moves on her.
** ''VideoGame/TalesOfSymphonia'': Presea Combatir is a twelve-year-old [[spoiler: [[OlderThanTheyLook really at the very least twenty eight-year-old]]]], SugarAndIceGirl with [[AnAxeToGrind a giant ax]] bigger and heavier than she is, which she can just pick up like it was nothing due to AppliedPhlebotinum. Cue titanic ass-kicking.
** ''VideoGame/TalesOfTheAbyss'': Anise Tatlin, at thirteen years old, is a full-fledged sergeant of the [[ChurchMilitant Oracle Knights]] who serves as the personal bodyguard to the head of her order, thanks in part to a size-shifting doll that [[MarionetteMaster she uses as a battle mount]]. Her predecessor and counterpart among the QuirkyMinibossSquad is Arietta the Wild, who also fits this trope as a dangerous combination of Beast Master and Mage.
** ''VideoGame/TalesOfVesperia'': Rita Mordio is a fifteen-year-old girl, who is probably one of, if not the smartest character in the cast, who [[spoiler: came up with an idea to destroy something not even an advanced ancient civilization could destroy.]] She's also a Game Breaker due to the fact that her Tidal Wave and Meteor Swarm spells are EXTREMELY abusable in Overlimit, essentially stopping any boss from moving. Yes, not even the final boss can stand up to, "Blah blah blah! TIDAL WAVE!"
** ''VideoGame/TalesOfXillia'': Elize Lutus is a twelve-year-old ElegantGothicLolita who is one of the most powerful channelers in the party - and remember, that's second to a legendary military hero and ''The Lord of Spirits''. She comes with a set of absolutely murderously awesome darkness spells, including an evil purple version of Dhaos Laser called IGNITE TERROR. Also she nearly killed two dragons by herself.
* ''VideoGame/{{Touhou}}'': Virtually any cast member who's young enough, or ''[[ReallySevenHundredYearsOld looks]]'' [[ReallySevenHundredYearsOld young enough]], fits this trope. In other words - nearly all of them.
** [[ReallySevenHundredYearsOld Flandre Scarlet]] takes this trope up to eleven with her ability to [[DeaderThanDead destroy absolutely anything]]
* So does with ''VideoGame/RosenkreuzStilette''.
* ''VideoGame/{{Valkyria Chronicle|s}}th'' giveth uth Aitha Neumann, the 12-year-old Thhocktrooper with a lithp. Altho a cathe of [[SmallGirlBigGun Thmall Girl Big Gun]]. And Aliasse!
* Clementine, the deuteragonist of season 1 [[spoiler:and protagonist of season 2]], rapidly becomes one over the course of ''VideoGame/TheWalkingDead''. She quickly reveals herself to be a fast learner, a resourceful thinker, and surprisingly effective at surviving the zombie apocalypse, even using her small size to sneak into potentially dangerous areas on many an occasion and to lure enemies into a false sense of security. By season 2 episode 1, she is still only eleven and has been poorly fed and rested for months. Despite this, she still escapes a gang of bandits (all fully grown men), survives being washed down a fierce river, and fights off a starving dog. Upon finding other survivors, the dog bite is immediately mistaken for a zombie bite despite her pleas, and she is locked in a shed for the night to see if she'll turn (the doctor of the group seemingly forgetting that if untreated, she'll die and come back regardless of what bit her. [[spoiler:So she breaks out of the shed, sneaks into the cabin, and via stealth and possible blackmail of a fully grown man, manages to acquire what she needs. This eleven year old girl then stitches the bite up by herself. A zombie then breaks into the shed, and she singlehandedly fights him off with improvised weaponry. The commotion brings the cabin's survivors rushing out. She is later recognised by the BigBad of the season's first story arc as the most ruthless and dangerous of the survivors, despite being by far the youngest.]]
* ''VideoGame/{{Wild ARMs 5}}'': Carol. She compounds this by looking like a clumsy little girl even while shooting giant rockets at enemies.
* ''VideoGame/{{Xenogears}}'' Maria and her {{Expy}}, Mai from ''VideoGame/XenoSaga''.
* ''Franchise/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]].
* The heroine from ''VideoGame/AHatInTime'', the Hat Kid, is a little girl who is able to beat up beefy guys three times her size using her [[ParasolOfPain umbrella]]

[[folder:Visual Novels]]
* Sara Smith of ''[[VisualNovel/BlissStageLoveIsYourWeapon Bliss Stage: First and Final Act]]'' is an extremely powerful Pilot with a nearly unbreakable [[HumongousMecha ANIMa]] formed from her relationship to her brother. She's also ''thirteen.''
* ''VisualNovel/FateStayNight'''s Ilyasviel von Einzbern; made all the more apparent considering her servant is Berserker. Specifically of the OlderThanTheyLook type, [[spoiler: what with being a (sort-of) [[ArtificialHuman homunculus]] and all]]
** Saber may also count since she is a very tiny girl with a physical age of around 15-16.
* ''VisualNovel/HigurashiWhenTheyCry'': A bunch of paranoid kids who spend most of their time killing each other in a variety of horrific ways may seem like an odd choice for this trope, but several of the girls definitely have moments that define them as {{Little Miss Badass}}es, mostly in Kai when ThePowerOfFriendship is at its' strongest. Rika, however, takes the cake for managing to endure [[spoiler:being caught in a Groundhog Day-style time loop--in which ''every single loop'' ends in her death--for over 100 years]] and ''not'' go screamingly insane long before the series proper even begins.
* Say what you want about [[ReplacementScrappy Erika]] of ''VisualNovel/UminekoWhenTheyCry'', but that girl is a lot scarier and a lot tougher than she looks. [[spoiler:She killed Beatrice]], for crying out loud!

[[folder:Web Comics]]
* Ruby Gem, the little vampire girl from ''[[http://www.monsterful.com/ Monsterful]]'', and her special transformation the VSV (vampiric spartan viking) makes her even more badass.
* ''Webcomic/AntiHeroForHire'' [[http://www.antiheroforhire.com/d/20071210.html Malvagia]]. Fourteen-year-old bounty hunter, practitioner of WaifFu, and one of very few villains to tangle with Shadehawk and come out ahead. She's the [[InTheBlood niece of a crime boss]], too.
* ''Webcomic/GrimTalesFromDownBelow'': [=MiniMandy=].
* ''Webcomic/HeadTrip'': Lillian. When a JerkJock was hitting on her and wouldn't take no for an answer, she broke his nose. Apparently, this has happened before.
* ''Webcomic/{{Homestuck}}'': Rose is dangerously handy with a pair of knitting needles, as an ogre [[EyeScream painfully learned]] at his expense. She also happens to be a LittleMissSnarker just to put icing on the cake of badassery.
** And that was ''before'' she got the [[ArtifactOfDoom Thorns of Oglogoth]].
---> ''[[http://www.mspaintadventures.com/?s=6&p=003716 WELCOME TO THE PARTY MOTHERFUCKERS]]''
** The trolls qualify as well. Vriska is a prolific SerialKiller due to the need to [[HorrorHunger feed]] her [[AbusiveParents lusus]], and Terezi is a MagnificentBitch who thinks [[DisabilitySuperpower being blind]] is ''[[CursedWithAwesome awesome]]'' and [[{{Troll}} great for messing with people]]. Nepeta, while [[{{Moe}} frighteningly adorable]], is an exceptionally skilled huntress with WolverineClaws, and even [[OnlySaneMan Kanaya]] [[GirlWithPsychoWeapon fights with a]] {{chainsaw|Good}}. Aradia used to be an archeologist who could talk to the dead, but is a TimeMaster now instead. Feferi has contact with her EldritchAbomination parent everyday, and has fought huge beasts with Eridan together to feed it.
* In ''Webcomic/{{Housepets}}'', Grape turns out to be this in "Housepets Babies!" when she [[CurbStompBattle curb-stomps]] [[http://www.housepetscomic.com/2012/02/06/ten-gallons-of-tailwhipping-in-a-five-gallon-can/ an alligator and a human kidnapper]] [[BroomstickQuarterstaff with a broom]].
* ''Webcomic/MegaTokyo'' uses the tag-line "Ph34r teh Cut3 0n3s", often in reference to the main character, Piro's, inevitably cute-and-highly-competent game characters. The comic itself also contains at least one example: the enigmatic Tohya Miho, whose true powers and purpose have yet to be revealed -- but who is [[http://www.megatokyo.com/strip/1068 "hardcore, badass dangerous"]]. Recently, Largo managed to turn [[spoiler:Yuki Sonoda]] from MagicalGirl to Little Miss Badass, much to her discomfort over such "lack of cuteness".
** Ping fills the trope when she's angry, since she can lift and throw busses, and chase people with a street lamp. The best example is when she [[spoiler:threw a giant turtle ''through'' the top of a skyscraper, crushing Ed and his {{BFG}} in the process.]]
---> '''Ping''': ''[[http://megatokyo.com/strip/376 That was very rude, Mr. Turtle!]] [[http://megatokyo.com/strip/377 You've made my hair all stinky!]]''
*** Second place to this would be the time she threw Ed out the window. Her aim was slightly off, so his head clipped the wall. And left a neat head-shaped hole right through.
* [[http://oglaf.com/son-of-kronar/2/ She... is truly my son.]] (NSFW) Badass straight out from the [[MisterSeahorse "womb"]].
* ''[[http://www.superstupor.com/sust04092008.shtml Super Stupor]]'' by [[Webcomic/SomethingPositive R.K.Milholland's]] presents a GenreSavvy parody.
-->'''Villain''': It's like the younger and cuter they are, the worse they're gonna kick your ass. If that was a four year old playing with a kitten out there, I'd offer her your dead body just to be on the safe side.
* ''Webcomic/VanVonHunter'': Parodied by Ultimate Evil: an eight years old who has mastered the most powerful and evil spell (by skipping to the end of the magic book and memorizing the ultimate spell without learning all the lower level spells first). She almost immediately sides with ''[[DesignatedHero the heroes]]'', and thus isn't a TykeBomb.
* Tycho's niece Anne from ''Webcomic/PennyArcade''. There's a reason her nickname is Annarchy...

[[folder:Web Original]]
* The ''Roleplay/GlobalGuardiansPBEMUniverse'' Heart Girl. Imagine Superman as a nine-year-old blonde girl with pigtails.
* ''Roleplay/OpenBlue'', in past incarnations, has had a propensity for these kinds of characters, most of them products of [[TheEmpire Avelion's]] [[TykeBomb Espartano Project]]. Presently, the only one around is Janice Cervantes, who actually escaped her training and is now a {{pirate}} captain... at the age of 14...
** As of v5, the concept has been recycled, except they now work for Remillia. However, so far, we only see the more grown up ones.
* Music/{{Vocaloid}} Special mention must go to Rin Kagamine. She is the youngest of the entire Vocaloid Roster (forget [[TheScrappy Yuki]]), and not only is she [[http://www.youtube.com/watch?v=ebAKoRcYFTA cute]], she is also [[http://www.youtube.com/watch?v=-NeioDa87QI not]] [[http://www.youtube.com/watch?v=J4yzw_QJ21E to]] [[http://www.youtube.com/watch?v=0Ox5-fEH4Ww be]] [[http://www.youtube.com/watch?v=ZVFfeTIWWco trifled]] [[http://www.youtube.com/watch?v=fKAGVTV9WsQ with]].
* The Literature/WhateleyUniverse's [[BewareTheNiceOnes Generator]]. She's 14, but looks 10. Cute as a button, and loves Hello Kitty. She once destroyed a Syndicate hardsite, killing pretty much everyone who got in her way. After being chained to a table, having her knee smashed with a hammer, and then getting stabbed through the heart so hard the weapon jammed in the table under her.
** Let's not forget the time she was attacked by a huge 9-foot-tall werewolf. She let him punch her, [[CrazyPrepared revealing a bear trap hidden inside her spirit-clone's face]], then nailed him to a tree using psychically animated railroad spikes, then casually proceeded to ''brand'' "I attack little girls" on his chest with mithril.
* In Podcast/RiffTrax' ''Film/TheHungerGames'': "Who'da thought Franchise/{{Batman}} would die so easily in the first Hunger Games? That 12-year-old girl just killed him right out of the gate."
* ''Podcast/WelcomeToNightVale'' has given us Tamika Flynn, the twelve-year-old girl who not only survived the Night Vale Public Library's Summer Reading Program--the first child to do so in years--but led out a band of survivors while brandishing the severed head of the [[TheDreaded Head Librarian]] and a blood-spattered Sticker Chart. She's now leading a militia of children.
* ''WebVideo/VaguelyRecallingJoJo'', High Priestess, who happens to look like [[WesternAnimation/ThePowerpuffGirls Blossom]] in this adaptation, pummels Jotaro and the others effortlessly at first.
* ''Blog/TheBlackLegionOfTheDarkLordSketchMelkor'' has Sketch, who founded a cult, is supposedly [[GodInHumanForm an incarnation of]] [[BigBad Melkor]], and [[AlternateHistory took over]] [[http://beyonddesolation.tumblr.com/post/67328370366/fake-of-house-spoiler-submitted-our-conquest-of Canada]]. She's [[ArsonMurderAndJaywalking also still in high school]].
* Juliana Rivas in ''Literature/VoidDomain'' is fourteen years old at the start of the story. She drastically eclipses her peers in terms of power and magical ability. Alongside a fellow badass, she found herself in a handful of fights before her first year of schooling finished.

[[folder:Western Animation]]
* In ''WesternAnimation/JackieChanAdventures'', Jade is surprisingly tough and resourceful, and has gotten Jackie's butt out of trouble on numerous occasions (even if she sometimes puts it there).
* ''WesternAnimation/AvatarTheLastAirbender''; [[TheLadette Toph]], the self-proclaimed "greatest earthbender of all time." Best not to disagree with her on that.
** Extra points for not only being [[{{Moe}} adorable]] but also being [[LittleMissSnarker snarky]], thus allowing you the experience of being sarcastically quipped at by a human Skipper doll.
** Ty Lee as well. She's a {{Moe}}, a GenkiGirl, and a PerkyFemaleMinion... who uses her trademark PressurePoint chi blocking to K.O. opponents on an almost OncePerEpisode basis.
** And of course, Katara herself. She starts off as a beginner Waterbender, but gradually becomes more and more powerful, to the point that she's able to [[spoiler: take on Azula ''while the latter's Firebending was enhanced by Sozin's comet'' in the GrandFinale]].
** Korra from ''WesternAnimation/TheLegendOfKorra'' started Water-, Earth- and Firebending when she was ''four'' (Avatars aren't told they're the Avatar until they're sixteen, even Aang didn't figure out how to bend the other elements on his own). She terrified the {{Old Master}}s that came to test her and declared, "[[BadassBoast I'm the Avatar and you got to deal with it!]]"
** Also from ''WesternAnimation/TheLegendOfKorra'', we have Tenzin's daughters Jinora and Ikki who, along with their brother [[BadassAdorable Meelo]], [[spoiler: come to Lin Beifong's aid when she's getting beaten by the Equalists who are attacking Air Temple Island. And proceed to wipe the floor with said Equalists]].
** Jinora continued to be a badass in Books 2 and 3, being Korra's spiritual advisor and saving the day in both books' finales: in Book 2, [[spoiler: she showed Korra that Raava was still alive after Vaatu-powered Unalaq had destroyed it, allowing Korra to recover Raava and her Avatar state]], and in Book 3 [[spoiler: she and the other Air acolytes saved Korra's ''life'' by stopping Zaheer from suffocating her,]] and she [[spoiler: finally became an airbender master!]]
* ''WesternAnimation/{{Ben 10}}'' Ben's cousin Gwen (and to a lesser extent, her EvilCounterpart Charmcaster). Not so much in ''WesternAnimation/Ben10AlienForce'', where they have both [[SheIsAllGrownUp grown up considerably.]]
* ''WesternAnimation/GormitiTheLordsOfNatureReturn'': Jessica. Other than being one of the chosen ones and wielding the powers of the Air Tribe, she also boasts a orange belt in judo. [[YouGoGirl And she beat]] [[TheHero Toby]] [[YouGoGirl in the school tournament!]]
* ''WesternAnimation/InvaderZim'': Gaz is all badass. The fact that she's only around 10-12 and has already beaten the living crap out of her older brother at least three times for bothering her; coupled with the fact that she terrorized a guy for taking the last video game system in stock that was rightfully hers, making her qualify.
* ''WesternAnimation/JimmyTwoShoes'': Heloise, an EnfantTerrible who spends her free time beating up anyone who displeases her and her on-the-clock hours working for {{Satan}}.
* ''WesternAnimation/ThePowerpuffGirls'': All three of them but most noticeable, Buttercup.
* ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'': Mandy. Wears pink, is blonde, snarks almost constantly, and makes the Grim Reaper her personal bitch in the first episode.
* ''WesternAnimation/TheSimpsons'' has Maggie Simpson, whose exploits include...
** Shooting Mr. Burns.
** Knocking out Homer by bonking him on the head with a mallet. Being strong enough to pick it up is badass enough, but when you can actually knock someone unconscious with it... Plus, let's not forget Homer can withstand: Several punches to the head, a Chair to the head, Being smashed with a Wrecking ball, falling down a deep chasm head-first, survive being hit by a cannon ball, and has drunk himself silly for the past two decades. Knocking him out with one hit alone is not an easy task.
** When Homer is targeted by the Mafia for starting a security business. Maggie picks up a pellet shotgun and opens a can of whoopass on them, one by one. Then, when Homer and Marge walk into her room, she hides it under her bed and pretends to be asleep, only to look at the camera and smile once they leave. Paired with a CrowningMusicOfAwesome.
** In TheMovie, she drops a rock on the head of Russ Cargill, knocking him out, just as he's about to shoot Homer and Bart. Bart and Homer leave her there and she still manages to get back into the arms of Marge before they do... plus she got out to the canyon in the first place.
*** Also where she scares off Mister Teeny (the chimp) with a broken bottle and a glare when the mob comes to the house.
** In the episode "Midnight Towboy", when Homer is imprisoned in a basement of a tow truck driver, Maggie saves him by riding on Santa's Little Helper to the place, and attaching the guy's towhook to the cellar window bars.
** In "[=MoneyBART=]", when Lisa wants to practice fencing, she tries it with Maggie, who defeats her spectacularly.
** In "Little Girl in the Big Ten" as Homer makes his parenting rounds, Bart is in his bubble, Lisa is missing and Maggie is fending off a crazy raccoon.
** In "Hello Gutter, Hello Fadder", Maggie swims into the ocean and pull's her drowning father to shore. Given her age and weight, that's practically toonforcing.
** Note that all of these except for the first (which was an accident) happened after the mass {{Flanderization}} of all characters. TropesAreNotBad, indeed...
* ''WesternAnimation/TitanMaximum'': Claire is something of a subversion in that despite that she looks and acts like a little girl [[OlderThanTheyLook she's actually 21 according to Gibbs]].
* ''WesternAnimation/TransformersAnimated'', supervillain Professor Princess (yes, that's both her pseudonym and her ''real name'') wears frilly dresses and rides around on a flying pony named Powdered Sugar. Also she can beat up Bumblebee (granted [[TheWorfEffect pretty much anyone can do that]]).
** [[spoiler: And now Sari seems to have hit that point too...]]
* All the female operatives in ''WesternAnimation/CodenameKidsNextDoor'' some more than others. Numbuh Three was able to outfight Mr. Boss ''by herself'' in one episode, while Numbuh Five regularly takes on ''several'' adult Mooks by herself and wins.
* Spinelli from ''WesternAnimation/{{Recess}}''.
%%* [[WesternAnimation/StarWarsTheCloneWars Ahsoka]] [[ThisIsForEmphasisBitch kriffing]] [[WesternAnimation/StarWarsTheCloneWars Tano]].
* In ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', Scootaloo fits this role. Whether it's performing extreme stunts at high speed on her scooter or ziplining through the treetops, Scootaloo will be first in line whenever the Cutie Mark Crusaders do anything athletic, physical, or endangering to life and limb.
* Yanit from ''WesternAnimation/TheMummyTheAnimatedSeries'' is an underrated example; she can fly a plane like a pro, amongst other things.
* Yin from ''WesternAnimation/YinYangYo'' appears to be a cute, tiny rabbit but she's pretty talented with magic and can take on enemies much bigger than she is. Aside from her magic and strength, she can use her wits when needed. Lina could also count once she starts using Woo Foo.

[[folder:Real Life]]
* [[http://www.cracked.com/article_16497_7-people-who-cheated-death-then-kicked-it-in-balls_p2.html Alexis Goggins]], a seven-year-old girl, who jumped in front of her mother's gun-wielding boyfriend and [[TakingTheBullet took]] ''[[TakingTheBullet six bullets]]'' for her mom. [[MadeOfIron And]] ''[[MadeOfIron survived]]''.
* [[ImprobableAimingSkills Annie Oakley]] started hunting professionally at the age of nine.
* The girl who threw a badger at UsefulNotes/TheodoreRoosevelt while campaigning. No longer a little Miss, but still was when she was a child. Badass because: 1) She caught a badger, 2) Decided it was cute and fluffy enough to actually name, 3) [[RefugeInAudacity Tossed the Badger]] at [[OurPresidentsAreDifferent Theodore "President Action" Roosevelt]]. 4) Roosevelt decided the badger or the girl was badass enough to allow the badger to live with his bear.
* [[http://minnesota.publicradio.org/display/web/2009/10/23/young-hunter This girl.]] No moose is a match for her mad skills.
* [[http://www.telegraph.co.uk/news/worldnews/asia/india/6253878/Worlds-youngest-female-karate-black-belt-arrives-in-UK.html Varsha Vinod]], 5-year old karate black belt.
** Complete with [[HairDecorations pink ribbons]] and GirlishPigtails. That is some ''amazing'' GAR-{{moe}}, right there.
* [[http://www.grindtv.com/outdoor/blog/32338/little+girl+shows+remarkable+poise+in+stare-down+with+african+lion/ This]] ''three year old'' girl stared down a lion for five minutes.
* [[http://www.abcactionnews.com/dpp/news/region_tampa/meet-9yo-caitlin-meathook-kelley-a-mma-mixed-martial-arts-fighter#ixzz1uCU7pZof Caitlin "Meathook" Kelly]], 9-year-old (now ten years old) UsefulNotes/MixedMartialArts fighter with pink hair and a crush on Music/JustinBieber.
* [[http://sports.yahoo.com/news/internet-sensation--nine-year-old-girl-shredding-defenses-to-the-tune-of-25-touchdowns.html This girl]] She owns the boys.
* Malala Yousoufzai combines this with PluckyGirl, BadassBookworm and BadassPacifist, being a 15-year-old Pakistani activist who publically opposed the Taliban's ban on education. For her efforts, the Taliban had her shot in the head. She survived, fully recovered, and has declared her intention to continue pushing for reform, despite the very real danger of further fatally-intended retribution.
* [[https://www.buzzfeed.com/javiermoreno/this-9-year-old-girl-completed-a-24-hour-obstacle-course-des?utm_term=.lyGR4DjB7#.dppARWvBZ Milla Star Bizzotto]] who at 9 years old finished [=BattleFrog=]s 24-hour Xtreme race. Designed by a Navy SEAL, it consists of a 36 mile run, an 8 kilometer swim, and 25 obstacles that include a rope climb, crawling under barbed wire and climbing a 12-foot wall each of which she had to do six times, over six laps.
* Lydia Ko, a golfer born in Seoul but raised from infancy in New Zealand, absolutely fits. She first competed in her country's women's amateur championship in 2005, ''a few weeks before turning 8''. The amateur championship for ''adults'', mind you. Four years later (by now 12), she made the final match of the same event, losing to a 14-year old[[note]]who herself had competed in the 2005 event as a 10-year-old[[/note]]. Ko later became the youngest person ever to win a professional golf event at age 14 in 2011[[note]](a few months later, that record would fall to Canadian Brooke Henderson, a couple of months younger when she won)[[/note]]. And then she won multiple professional major championships and reached #1 in the world rankings while still a teenager.
* Ko was preceded as a women's golf prodigy by another member of the Korean diaspora in Honolulu native Michelle Wie. At age 10, she qualified for the U.S. Women's Amateur Public Links[[note]]a now-defunct United States Golf Association championship for amateur golfers who were not members of private clubs[[/note]], and won the same event at 13. She hasn't enjoyed quite as much success on the LPGA circuit as Ko, but has picked up a major championship win of her own.
