Cute Bruiser: Western Animation

  • Jade from Jackie Chan Adventures is not only a cunning Guile Heroine and Combat Pragmatist, she goes into full-on Badass Adorable territory when kicking butt with martial arts, even beating a Section 13 secret agent into submission once.
  • Spinelli from Recess fits this trope to a T.
  • All three of The Powerpuff Girls, who are canonically the most powerful heroes in their world — the fastest, strongest, toughest, and most capable.
    • Next to them, you have (had) the Rowdyruff Boys, their Spear Counterparts. They'd probably punch your lights out if you called them "cute", though.
  • Toph Beifong from Avatar: The Last Airbender, a short, little, blind girl who can Earthbend circles around pro-wrestlers and crumple solid metal between her fingertips without breaking a sweat. It was mentioned on the DVD Commentary that Toph wasn't originally female (the Earthbender in the opening and by extension The Boulder was the original design), but they changed it partially because they liked the concept of a twelve year old girl kicking the asses of a bunch of people much larger than her.
    • Which was hilariously spoofed in "The Ember Island Players," with a big muscular guy playing as Toph. While most of the characters overwhelmingly hate their character depictions, Toph, in fact, loves hers.
    • She's also one of the two most powerful Earthbenders in the world, tied with King Bumi. They once had a fight to determine who was the strongest. They wound up having to stop in the middle because it might have given away their location. But they couldn't hear Sokka telling them to stop, so every other good guy and member of the White Lotus had to stop them. They're later seen planning a rematch.
    • In Sequel Series The Legend of Korra, Korra displays this trait as well. When the White Lotus Society first meets her, she is already bending three elements with skill...at about age four.
  • Dungeons & Dragons:
    • 8-year-old Bobby. Neither a little girl nor quite possessing super strength, but giving the squeaky-voiced little brother of the group a magic caveman club that causes earthquakes on impact has much the same "gotcha" effect.
    • His friend Diana the Acrobat, a 14-year-old gymnastics expert who has an extendable staff as her Weapon of Choice.
  • An early (male) example is Bamm-Bamm Rubble from The Flintstones, though his Super Strength was mostly done for laughs.
  • Teen Titans:
    • Starfire, an unusual tall example.
      • And, by extension, her sister Blackfire.
    • Terra isn't physically powerful, but her powers are more suited to blunt force than subtlety.
    • Beast Boy is a Rare Male Example.
  • Dave's sister Fang in Dave the Barbarian. She might be more of a parody of the trope, though.
  • Sandy Cheeks of SpongeBob SquarePants is clearly Bikini Bottom's strongest resident, occassionally challenging massive, heavily muscled fish and Larry the Lobster to weightlifting challenges.
  • Danielle in Danny Phantom. Being a clone of the main hero gives her all the powers she needs to butt kick.
  • Shayera/Hawkgirl in Justice League. While she is an adult, she is easily the tiniest (and most smash-happy) member of the Original Seven. Justice League Unlimited also throws in examples like Supergirl, Stargirl, and Black Canary.
  • Lisa Simpson in the Treehouse of Horror episode where she gains superpowers and becomes Clobber Girl.
  • Panini from Chowder - She gives a beating to Gazpacho and Gorgonzola in "The Bruised Bluenana" and "Hey Hey It's Knishmas" respectively.
    • In one instance she threatens Chowder into holding her hand while walking home.
  • In Tom and Jerry cartoons, Jerry the Mouse is usually on the receiving end of pounding and can only get upper hand through cunning and agility. But God help you if you hurt his friend - he will trash you and wipe the floor with your blue furry ass. Moreso with his cousin who doesn't even need the adrenaline surges to pummel cats.
  • Bunnie Rabbot from Sonic Sat AM, gaining Super Strength from being part robot.
  • June from KaBlam! can beat you so hard when she's in a bad mood, you might have to go to the ER. It doesn't help that she can lift stuff 5 times her size.
    • And Jetcat.
  • Jimmy Two-Shoes: Heloise is easily the smallest member of the cast. She's also the one you wouldn't want to piss off. Only slightly second to her is Saffi.
  • Jungle Boy from Johnny Bravo, although ironically enough Johnny Bravo is able to injure him quite easily.
  • Molly Cunningham from TaleSpin. If you ever piss her off, don't let her anywhere near your shins.
  • Sixteen's Nikki Wong maybe the smallest member of her group, but she is by far the strongest.
  • Kim Possible: Pretty teenage girl, cheerleader and scourge of supervillains, for whom kicking henchman ass is a hobby. Also her sidekick Ron's adopted little sister, Hana is a toddler with prophesied "monkey ninja" powers.
  • My Little Pony: Friendship Is Magic: Applejack, whose jobs are a cowgirl and an apple bucker, i.e. herding large animals and kicking trees.
    • To get an idea of how powerful she is, the episode "Fall Weather Friends" featured a strength contest between her and Rainbow Dash at one point. RD manages to simply hit the bell on the strength-test machine. Applejack? Thanks to years of applebucking practice, she completely destroys it. And Rainbow Dash herself isn't that bad. In the hoof-wrestling part she easily won over Applejack.
      • Also, seeming fragile flower Rarity, who, when forced into a fight, hardly relies on her magic at all and is far from helpless in combat. This includes straight out punching out a Mook or two at one point. Heck, in the pilot, she kicks a manticore in the face.
      • Fluttershy totally kills that bear! Actually, she was just healing his backache.
      • Really, any pony at all who can kick ass is this. It goes with the territory. Equestria does seem to have something along the lines of a military composed of brightly-coloured ponies.
  • Mabel from Gravity Falls is undeniably cute and packs a mean punch.
  • Isabella from Phineas and Ferb is very cute but also very tough. Also, she is not afraid to use said cuteness as a weapon, as shown in "Meapless in Seattle".
  • Yin and Yang for Yin Yang Yo are two cute, technicolor rabbit twins who fare pretty well despite their small statures. Yang who uses might, thus relying more on his strength certainly qualifies although Yin proves more than once she doesn't always need magic to fight.
