Little Miss Badass

Go To

"Tell them that Ellie is the little girl who broke your fucking finger!"
Ellie, The Last of Us

She has skills that far exceed what you'd expect from her appearance. Maybe it's because she is a bit strange, mature for her age, or doesn't look like her age at all. Vaguely similar to a Tyke-Bomb save she isn't necessarily groomed by a Big Bad, and may well be a Big Bad in her own right or at least The Dragon. Might be the fighting powerhouse on the good guys side and can be mistaken for just the Tagalong Kid until she unleashes the Waif-Fu.

The character may be quite cute and is often smart enough to use that to her advantage, quickly manipulating anyone stupid enough to 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. Often extends to what she's wearing, 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 Waif-Fu, and can be an example of Small Girl, Big Gun or Girl with Psycho Weapon. Can be a Cute Bruiser and/or a Pint-Sized Powerhouse, but doesn't rely on brute strength. If she doesn't have ridiculous strength, she would be Weak, but Skilled. Most noticeable in characters who look very young, since many characters tend to catch on to overpowered teenagers much quicker.

Compare Enfant Terrible. May belong to a Badass Family. May grow up to be a Lady of War, although often with a touch of Femme Fatale. If lacking in charisma, she would be an Action Girl, or possibly Dark Action Girl.

Contrast Badass Adorable and Tyke Bomb; 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.

    Anime and Manga 
  • The quiet, petite Kirino Kotori of Ai Kora turns out to be Heir to the Dojo of a ninja clan, and also has a rather nasty temper on her.
  • Angel/Tenshi/Kanade Tachibana from Angel Beats!. She's as close as you can get to a Protoss Zealot and Agent Smith packed in a small girl's body, although isn't evil like the latter and isn't an alien like the former.
  • Hatoko, five-year-old controller of Suzuka from Angelic Layer.
  • Attack on Titan's Mikasa had bullies run scared just seeing her and isn't shy about punching friends out (or throwing them against walls) when needed, and ranked 1st in the army academy amplitude test. We can all thank Eren for that.
  • Battle Angel Alita:
    • 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 World of Badass ZOT tournament. In the earlier stages of the manga they routinely slice up their opponents with Razor Floss, and apparently got Sech's arm this way before the main story. And they're no older than Sechs.
  • Sweet, adorable and harmless Elizabeth "Lizzie" Middleford of Black Butler turns out to be one when it's revealed in Chapter 57 that because she didn't want her fiancé Ciel to see her "uncute" side, she deliberately hid her badass side and did a very good job of it until, finally, when Ciel despite his best efforts ends up injured and unable to save her, Elizabeth candidly leaps into the air and takes down the zombies with swords in both hands, saying that she will save him and become the wife of the Queen's Watchdog.
  • Eve in Black Cat. She can turn her hair into nano-blades and cut you at a particle level.
  • Gretel in Black Lagoon. Despite being only 11 years old she has the ability to run and fire a Browning Automatic Rifle to great effect as well. 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.
  • 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.
    • Liltotto Lamperd looks like a very young teenage girl at most, but she's also one of the strongest and smartest Sternritter not amongst the Praetorian Guard who can fight Captain-class Soul Reapers with the power to effectively devour anything she wants. Out of the five Sternritter who attacked Byakuya post his Took a Level in Badass moment, Liltotto was the only one alongside Meninas not to fall. After Pepe mind controlled Meninas, Liltotto was able to defeat Meninas rather quickly without any visible injuries and managed to keep her alive. Pepe's initial target for defeating the competition was even Liltotto.
  • Meiling/Meilin of Cardcaptor Sakura. 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 Crazy Enough to Work.
  • A Certain Magical Index and A Certain Scientific Railgun:
    • Misaka Mikoto is the third strongest Esper for a reason.
    • Her roommate and Abhorrent Admirer Psycho Lesbian Stalker with a Crush, 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.
  • 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 One-Winged Angel. Then there's the other Big Bad, Priscilla. Just like Riful she's cute as a button but, again, she's probably going to eat your soul. After the Time Skip they threw in Miata who mixes it up by being just this side of Ax-Crazy.
  • In Code Geass, 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 Code Geass: Nightmare of Nunnally covers Anya's narative position in that work.
  • D.Gray-Man'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. 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 she only looks like a child. She's the second eldest Noah after Adam, aka the Millennium Earl, and has looked 12 for the last 35 years.
  • From Dance in the Vampire Bund, we have Mina Tepes, the Princess of all Vampires. She looks like a 10 year old girl when not in her true form but is several centuries old. She can also kill you in many different ways.
  • Emily from The Severing Crime Edge 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 Darker Than Black is getting there, thanks in part to time spent being yelled at by a supreme badass and in part to the Small Girl, Big Gun effect.
  • Daida "Punishment" Hibana in Deadman Wonderland 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 Detective Conan, despite being 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 Digimon Tamers, complete with Badass Longcoat and Cool Shades in her debut.
  • Cisqua of Elemental Gelade, 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.
  • Fairy Tail:
    • 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. 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 planning an entire city-wide battle between eight five-man teams based on how everyone 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 Arc Villain of the Sirius Island Arc and the Greater-Scope Villain of the first major portion of the series), Warrod Sequen (a member of the 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 The Black Wizard Zeref himself. Whom she was in love with until he Took a Level in Jerkass.
    • Sherria Blendy, the Sky God Slayer, is essentially Wendy but more confident and with pink hair instead of blue.
  • Veronica from Franken Fran, an Artificial Human 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 Fullmetal Alchemist has cute braids, a little panda and very good manners. She also keeps pace with Scar and Ed when fighting off monsters.
  • Mint Blancmanche in Galaxy Angel, although she's actually a teenager (just barely, at 15), who 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 Waif Prophet/Oracular Urchin... and she'll give you three chances. Then she can destroy cities.
  • Gangsta.'s Loretta Cristiano Amodio qualifies simply by already being the head of 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.
  • From Gunslinger Girl, the eponymous cybernetic assassins, pre-teen children salvaged from near death, trained and brainwashed to become Italy's most elite counter-terrorism unit.
  • Minnie May in Gunsmith Cats. Bit of a subversion as well since she's 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 Mad Bomber.
  • Haruka Nogizaka's Secret's Alice, a shy, sweet little maid with a spiked bat, brass knuckles and enough strength to crack open a street and create a ha.
  • Hell Girl: 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. She's also far older than she looks.
  • Hellsing: 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 it was amusing.
    • When Seras was younger, 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, smart-mouthed, samurai-like, special forces bodyguard in Iono the Fanatics.
  • 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 Karakuridouji Ultimo. 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 smiling and laughing during all of this.
  • One of the Kirby Anime's Ensemble Darkhorses, Sirica, counts as one as well, being a young Action Girl 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.
  • Lyrical Nanoha: In 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 Really 700 Years Old 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 no longer physically aging), and they have more to add to the mix, including Caro, a ten year old medic who can summon really big dragons, and Vivio, a clone of the legendary 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.
  • Morgiana from Magi: Labyrinth of Magic 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 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.
  • Michiko & Hatchin: 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 former gang lord; throwing rocks at the guy with a high-powered handgun.
  • Syal from Mother Keeper 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.
  • Nabari no Ou has some examples:
    • 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, she is actually a Cat. Who is about 300 years old. And is also immortal. That should pretty much explain it.
  • Negima! Magister Negi Magi:
    • The 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 "Strength Table". The Demon God sitting at the very top? Evangeline (with Chachamaru's help) took him down in a little over a minute [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.
  • Miyabi in Ninja Nonsense. She's the only regular who's even remotely competent.
  • Noir's Kirika. Quiet, sad, cute, and can kill in many creative ways. Taken to extremes when it's discovered that she shot Mireille's parents, when she was a tiny tot in overalls.
  • Omamori Himari'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 inside a whirlpool-ON LAND.
    • Then there's 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.
  • One Piece Film Z : Getting transformed into a kid doesn't cause Nami to lose any of her Badass Adorable-ness.
  • Mitsuki in 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 Bloodstained Black Rabbit from PandoraHearts could be the Trope Codifier 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 most powerful chain there is. Except she's not.
  • Believe it or not, Misty from the Pokémon 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).
  • Pokémon:
    • Pokémon: Mewtwo Returns: 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 Pragmatic Villainy.
    • All of the female 'Dex Holders in Pokémon Adventures qualify as this. Of note is Yellow, who everyone underestimates until she gets pissed off and completely crushes the competition.
    • The anime has at least two in Ash's Bayleef and Snivy. Best Wishes character Iris is this too...but not for the same reasons as in Pokémon White.
    • Phantom Thief Pokémon 7 has Lily who is, 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 Puella Magi Madoka Magica. She never flinches, she never falters, 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.
  • Rozen Maiden has a cast full of girly, childish magical dolls that are from the human perspective as good as invincible.
  • Lady Kayura in Ronin Warriors, who, according to 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 Rune Soldier Louie.
  • Shaman King 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 until Hao turned them against her and the rest of the Yoh-gumi. Now that's saying something.
    • And then there's Jeanne, the real leader of the X-Laws. At first sight, she's just a twelve-years-old cutie... whose furyoku levels are of the closest to Hao.
  • Slayers: Lina Inverse is clever cynicism personified — and people who know her only by name are often shocked to learn that this short, big-eyed, small-chested teenager is the infamous Dragon-Spooker and Bandit-Slayer herself.
  • Maka Albarne from Soul Eater is a young, sweet and friendly girl ... who wields a ginormous scythe. Yup.
  • Spice and Wolf's Holo is quite the tease, but has lived for centuries and could turn into a big bad wolf to maul anyone who tries to attack her or Lawrence.
  • Rio in Spiral. She lures a teacher to his death, blows up her own chest to hide the evidence, built the bomb that did it.
  • In Tiger & Bunny Kaede Kaburagi ends up becoming Sternbild's most badass little girl after developing superpowers. What other ten-year-old can claim to have saved almost every Sternbild superhero from a Mad Scientist's inescapable death trap?
  • Trinity Blood's Seth is both powerful and sneaky. And it turns out 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 Yu-Gi-Oh! 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.

    Comic Books 
  • The Adventures of Aero-Girl: Jacqueline Mackenzie is a little girl who has received Superhero training from her father, Battle Jack, to protect Foxbay from those who would do it harm.
  • The Authority: 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 leader of the team. (It probably helps that she's the resurrection, or regeneration, of previous leader Jenny Sparks.)
  • Batgirl. Although now a teenager, Cassandra Cain was revealed to have finished the majority of her assassination training at the age of eight. 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 Fan Nickname for Cassandra is "Little Miss Ninja Goddess".
  • Body Bags: Panda Delgado is a petite although buxom 14 (and a half) year-old - and a professional bounty hunter with a deadeye aim.
  • In Supergirl/Batgirl story Elseworld's Finest: Supergirl & Batgirl, 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.
  • Kick-Ass: 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.
  • Livewires: The Marvel Comics Mini Series included Gothic Lolita, the team's android muscle, who looked young and dressed in her namesake style of clothing.
  • Runaways from Marvel Comics: Molly Hayes is the eleven-year old physical powerhouse of her team and falls somewhere between this trope and Badass Adorable, Depending on the Writer. It's thus uncertain how much of the little kid persona we see is veil and how much is her real personality.
  • Sin City: Miho. Deadly little Miho.
  • X-Factor (2006): Layla Miller, as written by Peter David. Don't mess with her: she knows stuff.
  • X-Men:
    • Shadowcat was a master ninja (and experienced superhero and expert hacker) by the age of 14, thanks in part to some Year Inside, Hour Outside training by Wolverine's Evil Mentor.
    • 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.
    • Magik was the most sexualized of the female New Mutants. 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 Sonic the Hedgehog (Archie Comics). Went from being a Bratty Half-Pint to HUMILIATING the Iron King, a Made of Iron 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 Teen Titans 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, Black Canary 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 I Hate Fairyland 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 The Transformers: More Than Meets the Eye: 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.
  • Black Moon Chronicles: Pepette has a moment where she goes up to an Upper-Class Twit holding flowers... and rips a knife out of them, holding it to his throat.
  • Late in 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 Red Sonja: Sanctuary, her career in sword-swinging and ass-kicking began when she was only twelve years old as an enforcer to a goddess.
  • In Groo the Wanderer, the Princess Thais goes from Royal Brat to Little Miss Badass pretty quickly.

    Comic Strips 
  • Susie Derkins from Calvin and Hobbes is implied to play lacrosse and routinely beats Calvin senseless whenever he hits her with a snowball/water balloon.

    Fan Works 
  • The Mad Scientist Wars, we have two-year old Maxwell Eta, the youngest member of the 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.
  • A lot of Buffy the Vampire Slayer 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 DC Nation (who is VERY much alive in their timeline, thankyoumuch) is definitely shaping up here. Raised by The Arrow Family and 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 Firefly fanfic Forward in the form of Inducer One-One-Nine. While not as overtly powerful as, say, River, she makes up for it by having terribly powerful Mind Manipulation powers coupled with frightening subtlety - and is psychotic enough to be an Enfant Terrible too.
  • Tomoyo Daidouji gets this treatment in the later chapters Shadow Crystal Mage's epic crossover fic Takamachi Nanoha of 2814. It boggles the mind, doesn't it?
  • Toy Hammer has Emma. She's little, she's a miss, and she's certainly badass as she is fated to become the God Emperor of Mankind.
  • In the Black Lagoon fic "Four Pirates and a...Little Lady?" Revy's 13-year-old sister Rachel easily qualifies. 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 Ace Combat: The Equestrian War, but underestimating her is a surefire way to get hurt.
  • Adelle is an experienced combatant in The Tainted Grimoire.
  • In the Discworld fanfic of A.A. Pessimal, 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. Murder Most 'Orrible and 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 ''Hyperemesis Gravidarum for the way Mariella Smith-Rhodes (same family) and Rivka ben-Divorah (who on our world might get a job offer from Mossad) put their training into practice. note 
    • Johanna's daughter, Famke Smith-Rhodes-Stibbons, settled a fight with a fifteen year old boy at the Guild School by leaping up at him, grabbing his collar, and head-butting him breaking his nose. She was eleven at the time. note 
  • Marissa Picard 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 Crowns of the Kingdom, 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 Moe Anthropomorphism of the Enterprise (CV-6) from Pacific: World War II U.S. Navy Shipgirls 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 Zelda's Honor, 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 Josclyn in mid-air while trying to save Giana from almost certain death; she also convinced the dragon, Qargus, to help Link and the others and then appearing to save the day on a dragon herself; Saria also coming in to distract the Hunger demon while Navi revives Link and surviving for quite a while is also another example.
  • 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 Pokémon Reset Bloodlines, at age ten raided tombs looking for treasures and was able to beat the tar out of older kids trying to bully her.
  • Chloce Cerise of Infinity Train: Blossoming Trail is a ten-year-old girl traversing the Infinity Train with her steel pipe (or donut holer) that she uses to beat the hell out her opponents.

    Films — Animation 

    Films — Live-Action 
  • Buffy the Vampire Slayer would have been all of eighteen years old in the film, fighting super-powered vampires.
  • Subverted in Balls of Fury 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.
  • Battle Royale: Some of the more capable girls become this by necessity. Most notably, Mitsuko Souma and Takako Chigusa.
  • Chocolate: Zen, an autistic teenage girl who is martial arts savant.
  • The pre-time skip version of Cataleya in Colombiana. And this was BEFORE she learned how to kill people.
  • Dune: Alia. Even more so in the novel. While the David Lynch film either glosses over it or fails to explain it, in the scene from the movie after she 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 systematically killing the enemy wounded.
  • Friday the 13th:
    • Part VII: The New Blood: Tina Shepard, who uses Psychic Powers 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.
    • 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.
  • Hanna: Due to her genetic modification and intense training under Erik, Hanna is a tough-whip smart teenage girl who's very capable of defeating even much more experienced adults using her combat skills.
  • Hard Candy: Haley Stark (Elliot Page) kicks major pedophile ass.
  • In Kick-Ass, 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 Darkened Building Shootout and the Executive Suite Fight. She swears more and kills more people than all of the other characters combined, and is easily the most popular character in the film. She also gave the Moral Guardians a heart attack.
  • Kill Bill:
    • 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 assassins in the world.
  • The Last Boy Scout: The daughter of Bruce Willis' 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.
  • Little Sweetheart 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 Alex Mercer at the start of Prototype, the photography skills of Frank West and the manipulation skills of an early-on Light Yagami.
  • A Nightmare on Elm Street:
    • Alice in The Dream Master, who literally did kung fu on Freddy.
    • Freddy vs. Jason: 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 Girls in either series (the hottest).
  • The Professional: Natalie Portman's character, Mathilda Lando, although she never actually goes through with anything.
  • Push: Cassie Holmes (Dakota Fanning).
  • 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 the movie adaption of Tomorrow; When the War Began takes out a group of soldiers in the climax and is shown carrying grenades at the end. Truthfully, it isn't really her choice.
  • True Grit (2010 version): Mattie Ross, not so much for being a killer (although she does kill Tom Chaney) but for being utterly impossible to intimidate. Also you do not want to haggle with her.
  • Kitty Pryde. In X-Men: The Last Stand, she made the Juggernaut her bitch!
  • Zombieland: Little Rock (Abigail Breslin).
    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 Annie, Annie is clearly more than a Heartwarming Orphan. She's managed to stomp her evil caretaker's foot and make it hurt, outrun police officers, stuff boys into trashcans, break her adopted father's leg (by accident while showing him what she's learned earlier) and 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 Red Eye. 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 Kingsman: The Secret Service. She's the tiniest of the Kingsmen candidates, but proves herself more than capable of handling any given situation.
  • Logan: Laura/X-23 is a Tyke Bomb Screaming Warrior 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.

  • The heroine of "The Adventures of Isabel", a poem by Ogden Nash 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.
  • Bastille from Brandon Sanderson's Alcatraz Series, at age 13, is the youngest person to have become a Knight of Crystallia. Her training and being bonded to certain crystals makes her incredibly fast and strong. Underestimate her and you'll be at the receiving end of her massive crystal sword, or at least her handbag.
  • Between the expertise and the body count, Sarah from Billy & Howard exemplifies this trope. Halfway through the second book she grows into a Lady of War.
  • The little Whistler girls of A Brother's Price, once they're above eight or so, all seem to be this. They were given 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.
  • Skeeter Traps from Chronicles of Magic 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.
  • Jasmine in Deltora Quest. When their group finds themselves caught up in the gladiatorial Rithmere games, it's not Barda who wins, or Lief, or even Glokk. It's her.
  • Neal Stephenson's post-cyberpunk novel The Diamond Age:
    • One of the many convoluted subplots revolves around a 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 Great Big Book of Everything, that was supposed to be a unique item for the granddaughter of the richest man on earth. Being Chinese, they also were all trained in 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 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. She received the original of the Great Big Book of Everything, 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 when Nell shows up, she immediately has a fanatically-loyal army of badass gangster-killing twelve-year-old girls at her absolute command.
  • Szelma of Dora Wilk Series 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.
  • Dragaera: Thou shalt not mess with Devera. Seriously. Sure, she looks about eight, but she once ate a Jenoine. Admittedly, she was a dragon at the time, a form in which she's unlikely to be underestimated, but still.
  • Lessa of the Dragonriders of Pern definitely counts. She survived a Hold-wide massacre at the age of 10, and went on to use her Psychic Powers 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.
  • Ivy the Archive from The Dresden Files. 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 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, the Big Bad for the book sets off an Evil Plan 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 fallen angels in their heads. And she does it all with a Restraining Bolt. To add to this, just to conjure enough power to create the Restraining Bolt alone required them calling on Satan.
    • And further perspective must be said, the Big Bad 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.
    • Word of God holds that 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.
  • Serroi, of Jo Clayton's The Duel of Sorcery and Dancer trilogies, is a Magic Knight who's been training as a soldier since she was thirteen. She's about four and a half feet tall, and at the age of twenty-seven to thirty, doesn't have to put much effort into passing for twelve.
  • Ingrid, the main character of the Echo Falls Mysteries series, is a middle school-aged girl who has single-handedly gotten herself out of such situations as being chased by the Big Bad and being kidnapped, Bound and Gagged!
  • Petra Arkanian from the 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.
  • 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 Government Conspiracy which wanted to make a Tyke Bomb out of her... and when her father was killed by them, it wasn't long before the running and screaming started. And then she got really nasty: she talked to the press.
  • Arguably, all the female cast in Gone, but especially Brianna, the youngest Action Girl of the series.
  • It's glossed over, as it happened about eight years before the book actually starts, but the protagonist of Graceling once killed her perverted distant cousin with one blow. When she was eight.
  • Halo:
    • Halo: The Fall of Reach: 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. 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.
    • Halo: Ghosts of Onyx: 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.
    • Halo: The Cole Protocol: As a child Spartan-II trainee, Adriana kicked the ass of several trained Marine guards during her and Jai's numerous escape attempts.
  • Harry Potter:
  • In Robert A. Heinlein's Have Space Suit – Will Travel, 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 Wormfaces, as well as a radio beacon to summon the Mother Thing's people for help.
  • Helen Zilwicki, in her first major appearance in the Honor Harrington stories, is twelve years old, and she kills a couple of men who attempt to rape her, with her bare hands.
  • Huge armies of Little Miss Badasses are the focus of Henry Darger's monumental fantasy novel In the Realms of the Unreal. 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 Girls with Guns and lots of Child Soldiers.
  • Kirsty from Johnny Maxwell Trilogy. She left the local karate club because no boy would dare to come near her.
  • Journey to Chaos: Zettai evaded Ceiha's secret police for an extended period of time before they caught her.
  • Lily, in Lilliput by Sam Gayton. Underestimated by almost everyone, since she's only a few inches tall and a child, after being kidnapped at the age of six, she almost immediately begins hatching escape plans. Later she goes into battle against (to her) giants armed with a sewing needle as a sword—and wins.
  • Virra from Loyal Enemies is a seven-year-old half-elf girl. She is, however, a great archer, a Knife Nut in training and a member of 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.
  • Rye's toddler sister Lottie in The Luck Uglies. Her eagerness to leap into a fight with a ladle and pot helmet is Played for Laughs most of the time, but when a corrupt constable with a hobby of harassing her mother won't back down, the little girl takes her mother's Chastity Dagger and stabs the officer in the foot. It only aggravated the situation, but quite the feat for a kid still in potty training.
  • Sorry from Steven Erikson's Malazan Book of the Fallen series exemplifies this trope. In the first book, she joins the most badass squad in 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 Professional Killer Kalam Mekhar queasy and the squad mage Quick Ben jump at shadows. Of course, she's also possessed by the Patron God of Assassins.
  • 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.
  • Most of the female Meq in The Meq, since the majority of them are over a thousand years old. Geaxi probably tops them all though and definitely fits the trope best.
  • The Millennium Trilogy: Lisbeth Salander is this trope.
  • Likewise 12-year-old Hazel Meade (later Stone) in The Moon Is a Harsh Mistress.
  • The Paladin of Shadows books have Creata. Described as small and delicate, she disembowels a sex slaver with a drilling laser in Choosers of the Slain and calmly blows his brains out afterward.
  • Basically all of the female demigods in Percy Jackson and the Olympians fit this trope. Most of the Aphrodite daughters don't really do anything, but some special mention must go to 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 Older Than They Look. Zoe Nightshade, for example, looks 14, but is at least two thousand years old. Artemis herself prefers to appear about twelve.
  • In 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 steal Sir Kai's sword so she can go after the man who instigated the mob. Kai is so impressed by this that he gives her the sword meant for his son (she's only thirteen, so it fits her better than his broadsword), and she not only exacts revenge on the man who started the mob, but the man who was giving him orders — by facing him in single combat.
  • In Rachel Griffin, the titular Rachel, a thirteen year old girl, is capable of calmly faking Brainwashing in order to get the drop on the demon-possessed Big Bad and shutting him down.
  • Red Moon Rising (Holt): Temple/Kalashava is nine years old, but has trained as a warrior and is a crack shot with a bow.
  • Redwall: Mariel Gullwhacker. Kicked the tail of a pirate king unarmed, then beat up a seagull several times her size with nothing but a piece of knotted rope.
  • Although she's not a prominent character, a girl named Kym in Return of the Emperor is a major example. She uses her looks (and her weapons) to knock out unsuspecting men and steal their stuff. She is used as part of the base for a smear campaign against Dusable's moron of a ruler.
  • From John Ringo:
    • As part of a Badass Family, Callie O'Neal in the series The Legacy Of The Aldenata is skilled in many forms of violent mayhem, coached mostly by her Retired Badass mercenary grandfather, at all of 13 years of age.
    • In the Black Tide Rising series, Faith is 13 years old, a bit taller than the norm for that age, and takes on herds of zombies thanks in part to training from her former special forces soldier father.
  • From The Sisters Grimm series: Sabrina, the self-proclaimed "Queen of the Sneaks" and her sister Daphne.
  • Arya Stark from A Song of Ice and Fire. 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 assassin's guild that can change their identities/faces on a whim. She also has a psychic bond with a giant man-eating wolf.
  • The Stormlight Archive: Shallan Davar was like this as a child, to the point that at age eleven she killed her mother when he mother tried to kill her. Deconstructed in that this event broke Shallan into a million pieces; she didn't speak for months afterwards, and spent years hiding inside herself, refusing to confront anything.
  • Rachel from the Sword of Truth novels becomes quite the badass by the end of the series. Trained by the Badass Normal of the series, it's hard to see how she couldn't be. By the eighth book, most specifically. Nothing quite like 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 Badass Normal adoptive father, so flip him a few knives for him to fight with... from UNDER YOUR SKIRT.
  • Emily Roland, of the 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.
  • Margo Smith of Time Scout begins her training slightly before she shows up on Time Terminal 86, but takes a level when she shows up, and takes several more in the books that follow. All before she turns 18.
  • Jane, a millenarian vampire from 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.
  • Astra in Wearing the Cape: A Flying Brick, 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.
  • Tiffany Aching, in the Terry Pratchett novel The Wee Free Men. Hell, she's nine years old, and takes on The Fair Folk with a Frying Pan of Doom!
  • Vaness of The Witchlands 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 power.
  • In The Witches of Karres, 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 Parental Substitute.
  • Several characters in The Wolves of Willoughby Chase series, but especially Dido Twite. Her half-sister Is takes over the badassery for a couple of books late in the series.
  • Emilia in 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 warp reality with the power of make believe.
  • Nita Callahan (13-14 years old) and Dairine Callahan (11-12 years old) from the Young Wizards 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 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.
  • Worm: Missy Biron, a.k.a. Vista, is the youngest member of Brockton Bay's Wardsnote  team. She is also the longest-serving, and due to Brockton's supervillain-lead-gang problem and chronic manpower shortage in the Protectoratenote  their Wards team regularly sees serious action (contrary to the program's nominal purpose as a safe way for superpowered youths to get training and assistance); she once took on Hookwolf, one of the most dangerous and vicious Villains in the city, solo. She also has the highest PRTnote  threat rating, not merely of the Wards, but of all the Heroes in the city.

    Live-Action TV 
  • Out of all the characters in Round the Twist, 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 Heroes eventually becomes this, especially in the dark future.
  • Alex on Wizards of Waverly Place 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 Bloody Jack 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 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 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.
  • 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 a skilled assassin.
    • 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. Then she dies in a blaze of glory, taking down a wight giant before dying herself.
    Davos: I suspect if [House Mormont soldiers] are as fearsome as their lady, the Boltons are doomed.
  • Eleven from 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.
  • NCIS: New Orleans' 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.
  • 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.
  • Killing Eve: When Irina (who can't be older than twelve) is kidnapped by Villanelle (a total psychopath with a short temper, who's very pissed at Irina's father, and is currently waving a gun around), she responds to the whole situation with utter disdain, going out of her way to annoy the living crap out her captor. Even as Villanelle drags her around Moscow, threatens her beloved father, points a gun at her, and in general acts extremely unstable, Irina doesn't seem all that scared.
  • Good Omens (2019): Pepper fearlessly defies both Adam (even when it becomes clear that he's got supernatural power) and then the Horseman (well, Horsewoman) of War to their faces, kicking War in the shin, then wishing her away by advocating peace at Adam's urging.
  • Hanna: Hanna. She's a short, slim teenage girl, but is a highly skilled martial artist and quite good with firearms. Sandy is another example, though really all the Utrax girls may count, as they're just teenagers but have been trained as assassins from childhood. In fact, that's why they were chosen, as people don't expect them to be a threat.

  • Vocaloid Special mention must go to Rin Kagamine. She is the youngest of the entire Vocaloid Roster (forget Yuki), and not only is she cute, she is also not to be trifled with.

  • Wyvern from The Chimera Program arc of Cool Kids Table is a little fourteen-year-old Latina girl who, when she gets emotional, turns into an enormous dragon-like creature.
  • In RiffTrax' The Hunger Games: "Who'da thought Batman would die so easily in the first Hunger Games? That 12-year-old girl just killed him right out of the gate."
  • Welcome to Night Vale 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.

    Professional Wrestling 
  • Kaicho Ramu started appearing in the ring at age six. She wears Iron Maiden 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, triple suplex, and the 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.

  • Open Blue, in past incarnations, has had a propensity for these kinds of characters, most of them products of Avelion's 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.

    Tabletop Games 
  • Mekton Isami Shinzato from the Virtual game. A BLIND thirteen-years-old girl who is one of the most dangerous Humongous Mecha 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... harshly... with older male bullies.
  • Vampire: The Masquerade 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.
  • Warhammer 40,000: Age and power as a psyker are loosely related at best. Although, given 40K this is less Little Miss Badass and more Little Miss Walking Portal to Hell.
  • In d20 Modern, 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 Mad Max style vehicle stunts, scavenge old buildings for supplies, or many other things. Justified as kids have to grow up fast After the End.
  • In Legend of the Five Rings, 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.
  • Mythender: They're not necessarily female, but any Mythender with the Child Past is a little kid who just happens to be able to punch Cthulhu into the next zip code.

  • Into the Woods: Little Red Riding Hood, at least after her grandmother gives her a knife and a wolfskin coat.

    Video Games 
  • Ar Tonelico 2: Cocona pushes this beyond the limits. She not only was a 11-year-old girl who used 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 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... 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, 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 (Midway through the game she has her Boundary Gate (the construct that keeps Reyvateils separated from their respective Song Server) broken through), by the third game she's 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!
      • 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!
      • Oh, and by the way, have a listen to the song she sang in this event.
  • Arc Rise Fantasia: Spunky and enthusiastic Cecille is a Cute Bruiser, who can unleash a devastating amount of damage with her fists. Is also technically Older Than She Looks.
  • Backyard Sports: Luanne doesn't run. She's so fast, it looks like she's teleporting. Oh, and she's four years old.
  • 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 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.
  • Borderlands 2: The most talented Demolitions Expert on Pandora happens to be a slightly unhinged 13-year-old girl named Tiny Tina.
    • In the expansions, you can play as Gaige, the 16-year-old Gadgeteer Genius Vault Hunter, blasting her way through hoards of bandits and monsters with her homemade Robot Buddy.
  • Bunny Must Die! Chelsea and the 7 Devils: The protagonist Bunny, the second protagonist Chelsea, two of the devils and even some of the Mooks qualify.
  • The Capcom vs. series. Capcom seems to be thinking along these lines since Roll has a better track record than her brother Mega Man himself (Rock has only appeared once; Roll, at least twice). Because of that, Roll can have the distinction (Power Creep, Power Seep aside) of beating not only Onslaught and Yami, but also the ultimate badass of the Mega Man series!
  • Castlevania: Rondo of Blood: 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 Child of Light is a very young princess who gets sent to a Magical Land filled with monsters. She destroys said monsters with a huge sword and light magic.
  • Chrono Cross: Marcy. Leah's more a Cute Bruiser 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 Darkstalkers series. Bulleta/Baby Bonnie Hood. She's a monster-hunting Badass Normal, 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).
  • Disgaea: Etna who, at one point, reverses a Batman Gambit back onto her blackmailer and ends up kicking his ass from here to next Friday. Though she is 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.
    • Raspberyl in the third game.
    • And in the fourth there's Fuka Kazamatsuri, a fourteen-year-old Ordinary High-School Student who beats powerful demons and Living Weapons 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 Phantom Brave.
    • And of course there are most of the female generic units.
  • Drakengard has a six-year old Manah with evil magic powers as the leader of The Empire, and the game even calls her "the source of all evil."
  • Babette from The Elder Scrolls V: Skyrim is a 300+ year old vampire assassin with the body of a 10 year old girl. Also a master of alchemy, and one of two Dark Brotherhood members (besides the player) to survive the hideout being swarmed by soldiers and then exploding.
  • Elsword: Three main examples:
    • Eve, at least early on in the game, looks like a young girl, but is actually the queen of an ancient race of robots that can rip anyone who gets in her way a new one with blades, support robots and deathrays. Later on she doesn't apply, though, because her class paths end up with her upgrading her body, making her look older.
    • Luciela R. Sourcream looks like a little girl, but she's actually a high rank demon who, even with her powers sealed, can unleash bloody murder on anyone who gets in her way with a huge gauntlet that's as big as she is.
    • In late 2018, another little girl, Laby, was released as a playable character, and she's as much of a badass as everyone else. Her Sparky Child class path, which refuses to rely on her magic mirror Nisha, can knock the everliving daylights out of huge demons with nothing but her bare hands and feet, and enjoys every second of it.
  • Enchanted Arms: Yuki. One of the youngest people depicted in the game, and easily on par with an experienced knight in combat prowess.
  • Evil Zone 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 F-Zero GX.
  • The Final Fantasy series. Most of the games have a "Little Girl" archetype, that is, an immature or young female character.
    • Final Fantasy IV: Porom is only 5, but she can learn every single White Magic in the game. There's also Rydia, who gets a Plot-Relevant Age-Up in the middle of the game, but before that she definitely counts!!
    • Final Fantasy VI: 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.
    • Final Fantasy V: Krile. The Earth Crystal room's scene is what puts her ahead of all the others by far, personally.
    • Final Fantasy VII: 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.
    • Final Fantasy IX: 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.
    • Final Fantasy X: 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.
  • Fire Emblem: Radiant Dawn: Empress Sanaki.
    • Also 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 Fire Emblem Awakening, Nowi seems to be the deal... save for being an over 1,000-year-old 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 Fire Emblem Fates, the well-raised Mozu (an expy of Donnel), Elise and Sakura can become this when promoted, and the same goes to Hayato (an expy of Ricken); on the other hand, Nyx looks like an example of the trope but is actually an adult woman whose growth was stunted due to a curse cast on her as punishment for having been an Enfant Terrible version of this trope. The second generation has Kana (of either gender), Kiragi (Rare Male Example) and Midori.
  • Golden Sun: Dark Dawn 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 class changes, and even as a holy priestess can sicc dragons on the enemy. She has very little on-screen Character Development, but she's otherwise pretty capable of messing up anything that messes with her.
  • Grand Chase: The female cast. That being Elisis, Lire, Arme, and Amy.
  • Guilty Gear: Fanny, a nurse and fangirl of Dr. Baldhead from the little-known Guilty Gear Petit, who uses many of his moves and carries an oversized syringe larger than herself.
  • The heroine from A Hat in Time, the Hat Kid, is a little girl who is able to beat up beefy guys three times her size using her umbrella.
  • Hitman: Absolution 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.
  • Guns N Angel a Flash game. The protagonist who is apparently an expert with assault weapons and explosives.
  • Knights of the Old Republic: Mission Vao is fourteen years old, and Badass Normal. Yes, she has the lowest HP in your party. Yes, she's a sweet young lady higher on the Karma Meter than the party's Jedi. Yes, if you go to The Dark Side, 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 Zaalbar. Given that, her Berserk Button over being called or treated like a helpless kid is kinda understandable.
  • Ellie is this in The Last of Us. She shows her true colors near the end of the game after Joel gets impaled by an iron bar in the university, requiring her to protect him for the next couple months instead.
  • The Legend of Zelda:
  • Miyako Arima from Melty Blood 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 Arcueid, Ciel or Nrvnqsr Chaos certainly counts.
  • Sunny in Metal Gear Solid 4: Guns of the Patriots and again in Metal Gear Rising.
  • Onechanbara: Saki. She wields a katana, can withstand kicks from super strong cyborgs, jump off buildings, destroy pavements, cut a truck in half among other things with little effort.
  • Maeve from 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 magical darkness.
  • Every female playable character in Pokémon, and a few NPCs. Regarding the latter, Iris from Pokémon Black and White 2 is the crowning example, as she has become Champion of all of Unova.
  • Sengoku Basara 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 humongous hammer, and inspiring oddly sweet moments with the game's resident Mr. Fanservice Blood Knight.
  • Shin Megami Tensei has Alice. Nice girl who loves dolls? Sure. Insane sorceress capable of casting the deadliest Dark-aligned One-Hit KO attack and who charmed two Goetia demons into serving as her guardians by sheer force of cute? That too.
  • Sonic the Hedgehog has Amy, Cream and Blaze, who are respectively 12, 6 and 14 years old (Even though Blaze is Younger than She Looks). Despite their young age, all of them are more than capable of kicking plenty of ass and get an "awww" out of players in the process.
  • Star Ocean: The Last Hope: 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 Claws of Fury that scores something on the order of a dozen consecutive critical hits. Needless to say, jaws were dropped.
    • Lymle Lemuri Phi, the Magical Girl 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.
  • Super Robot Wars: Latooni Subota, whose calm, analytical approach to combat makes her a deadly opponent, even when she's wearing a frilly dress. And that goes double for her Humongous Mecha.
    • 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.
  • Tales Series:
    • Tales of Phantasia: Suzu Fujibayashi is a eleven-year-old Ninja girl with some fabulous fighting moves on her.
    • Tales of Symphonia: Presea Combatir is a twelve-year-old really at the very least twenty eight-year-old, Sugar-and-Ice Girl with a giant ax bigger and heavier than she is, which she can just pick up like it was nothing due to Applied Phlebotinum. Cue titanic ass-kicking.
    • Tales of the Abyss: Anise Tatlin, at thirteen years old, is a full-fledged sergeant of the Oracle Knights who serves as the personal bodyguard to the head of her order, thanks in part to a size-shifting doll that she uses as a battle mount. Her predecessor and counterpart among the Quirky Miniboss Squad is Arietta the Wild, who also fits this trope as a dangerous combination of Beast Master and Mage.
    • Tales of Vesperia: Rita Mordio is a fifteen-year-old girl, who is probably one of, if not the smartest character in the cast, who 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!"
    • Tales of Xillia: Elize Lutus is a twelve-year-old Elegant Gothic Lolita 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.
  • Touhou Project: Virtually any cast member who's young enough, or looks young enough, fits this trope. In other words - nearly all of them.
  • So does with Rosenkreuz Stilette.
  • Valkyria Chronicleth giveth uth Aitha Neumann, the 12-year-old Thhocktrooper with a lithp. Altho a cathe of Thmall Girl Big Gun. And Aliasse!
  • Clementine, the deuteragonist of season 1 and protagonist of season 2, rapidly becomes one over the course of The Walking Dead. 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. 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 Big Bad of the season's first story arc as the most ruthless and dangerous of the survivors, despite being by far the youngest.
  • Wild AR Ms 5: Carol. She compounds this by looking like a clumsy little girl even while shooting giant rockets at enemies.
  • Xenogears Maria and her Expy, Mai from Xenosaga.
  • Dragon Quest:
    • Dragon Quest IV: Young, little Princess Alevna escapes from the castle by kicking a hole in the wall of her third-story room and jumping out. It's also stated that this isn't the first time she's done it. When she joins your team, she is you best physical hitter.
    • Dragon Quest V:
      • Bianca goes ghost-hunting with the main character when she is eight. Unlike the Hero, she has already learned Fire spells.
      • Madchen may be eight but she packs firepower -several of the most powerful spells in the game- and isn't afraid to use it.

    Visual Novels 
  • Sara Smith of Bliss Stage: First and Final Act is an extremely powerful Pilot with a nearly unbreakable ANIMa formed from her relationship to her brother. She's also thirteen.
  • Fate/stay night's Ilyasviel von Einzbern; made all the more apparent considering her servant is Berserker. Specifically of the Older Than They Look type, what with being a (sort-of) homunculus and all
    • Saber may also count since she is a very tiny girl with a physical age of around 15-16.
  • Higurashi: When They Cry: 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 Badasses, mostly in Kai when The Power of Friendship is at its strongest. Rika, however, takes the cake for managing to endure 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 Erika of Umineko: When They Cry, but that girl is a lot scarier and a lot tougher than she looks. She killed Beatrice, for crying out loud!

    Web Animation 

  • Penny Arcade has Annarchy, Tycho's niece. She starts with a scary deep knowledge of classic gaming and other nerdy topics, then ends up swinging a bat'leth around in the middle of a Zombie Apocalypse.
  • Super Stupor by R.K.Milholland's presents a Genre Savvy parody with the Kid Hero.
    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.
  • Van Von Hunter: 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 the heroes, and thus isn't a Tyke Bomb.

    Web Original 
  • Whateley Universe: 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, 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.
  • The Black Legion of the Dark Lord Sketch Melkor has Sketch, who founded a cult, is supposedly an incarnation of Melkor, and took over Canada. She's also still in high school.
  • Juliana Rivas in Void Domain 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.

  • My Little Pony: Friendship Is Magic: 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.
  • In Jackie Chan Adventures, 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). Her skills in espionage, as well as breaking and entering stay with her throughout her life, as we see in one episode, she grows up to become an agent of Section 13. Her cunning will often impress her superiors.
  • Avatar: The Last Airbender:
    • Toph, the self-proclaimed "greatest earthbender of all time." Best not to disagree with her on that. Extra points for not only being adorable but also being 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 Genki Girl, and a Perky Female Minion... who uses her trademark Pressure Point chi blocking to K.O. opponents on an almost Once per Episode 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 take on Azula while the latter's Firebending was enhanced by Sozin's comet in the Grand Finale.
  • The Legend of Korra:
    • Korra 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 Masters that came to test her and declared, "I'm the Avatar and you got to deal with it!"
    • We also have Tenzin's daughters Jinora and Ikki who, along with their brother Meelo, 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, 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 she and the other Air acolytes saved Korra's life by stopping Zaheer from suffocating her by creating an actual tornado, and she finally became an airbender master!
  • Ben 10 Ben's cousin Gwen (and to a lesser extent, her Evil Counterpart Charmcaster). Not so much in Ben 10: Alien Force, where they have both grown up considerably.
  • Webby of DuckTales (2017), despite being a very excited Genki Girl, is equally as badass. She's incredibly resourceful, adventurous, and often has to get Huey, Dewey, and Louie out of trouble.
  • Gormiti: The Lords of Nature Return: 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. And she beat Toby in the school tournament!
  • Invader Zim: 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.
  • Jimmy Two-Shoes: Heloise, an Enfant Terrible who spends her free time beating up anyone who displeases her and her on-the-clock hours working for Satan.
  • The Powerpuff Girls: All three of them but most noticeable, Buttercup.
  • The Grim Adventures of Billy & Mandy: Mandy. Wears pink, is blonde, snarks almost constantly, and makes the Grim Reaper her personal bitch in the first episode.
  • The Simpsons 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.
    • In The Movie, 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 two (which were accidents) happened after the mass Flanderization of all characters. Tropes Are Not Bad, indeed...
  • Titan Maximum: Claire is something of a subversion in that despite that she looks and acts like a little girl she's actually 21 according to Gibbs.
  • Transformers Animated, 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 pretty much anyone can do that).
    • And now Sari seems to have hit that point too...
  • All the female operatives in Codename: Kids Next Door 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 Recess.
  • Yanit from The Mummy: The Animated Series is an underrated example; she can fly a plane like a pro, amongst other things.
  • Yin from Yin Yang Yo! 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.
  • Oh No! It's An Alien Invasion: All the female members of S.W.E.E.T. are little girls, since all the adults in the world were taken away by the Brainlings.

She survived, fully recovered, and has declared her intention to continue pushing for reform, despite the very real danger of further fatally-intended retribution.

  • 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 oldnote . Ko later became the youngest person ever to win a professional golf event at age 14 in 2011note . 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 Linksnote , 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.
  • Katherine Smart, who at 9 years old, had the presence of mind to remain quiet and still when a knife-wielding man entered her bedroom and abducted her sister, thinking, "If he knows you're awake, he might take you too, and you're the only one who's seen this", then immediately alerting her parents once she felt it was safe to leave her room. It was she who identified the kidnapper as someone who had done housework for the family over a year earlier, enabling the cops to catch the guy. The girl in question was Elizabeth Smart, who is herself an example of this trope—for 9 months, at only age 14-15, she survived an ordeal that would have broken most adults—starvation, repeated rapes, etc.
  • Greta Thunberg, very loudly and publicly shaming the heads of state of the entire world for their negligence in dealing with climate change and other existential threats. If you think that doesn't require absolute nerves of steel, accusing the most powerful people in the world who could have you disappeared in literally minutes, you might want to reconsider.
  • 4-year-old twins escape deadly wreckage, hike for help
  • This five-year old.
  • This 4 year old, who not only called 911 when her mother collapsed, but calmly took care of her three younger siblings while waiting for the ambulance.
  • Terry Jo Duperrault, who at only 11, survived an ordeal that would have broken most adults—witnessing the murder of her entire family by the skipper of their yacht (who had murdered his wife as well), then being abandoned on the sinking vessel by the killer. She was able to launch a dinghy and drifted for four days, being within hours of death from exposure when she was finally rescued. The moment her killer heard she'd survived, he committed suicide, knowing she could destroy the lies he'd told investigators when he himself was rescued.
  • Freddie and Truus Oversteegen were teenage sisters who served in the Dutch Resistance during World War Two. They would ride together on a bike, delivering messages, observing enemy patrols, shoot SS men to death...
