Adorably Precocious Child

This kid may not have even hit puberty yet, but acts as if always preoccupied with responsibility. They work hard at whatever they do and treat things seriously, but every once in a while they do indeed act like a kid (and hate the subsequent teasing). Usually not taken too seriously by anyone and hate being treated like a kid by adults, even if they secretly like the attention.

Often their family situation is problematic. They might be a lonely only child, although they could also have a big sister or brother they respect and admire. The Adorably Precocious Child can attach to the closest adult who lets them, creating an Intergenerational Friendship, and often finding a Parental Substitute. This is especially common if they're also a Bratty Half-Pint. Sometimes this works in reverse, and the adult character may have to defend themselves against unwholesome comments by other characters by insisting they're Like Brother and Sister, or, more often, explain that the child is Like a Son to Me, or even a Replacement Goldfish for a dead relative.

Compare with Cheerful Child, Innocent Prodigy or Wise Beyond Their Years; contrast Troubling Unchildlike Behavior. Sometimes also a Token Mini-Moe. See also Kids Raiding the Wine Cabinet and Entertainment Above Their Age.

Examples

Animation

• Masha from Masha and the Bear is said to be 3 years old and yet she can perform daunting tasks and speak properly.

Anime and Manga

• Chiyo Mihama from Azumanga Daioh. She's always in a good mood, very childish and cute as a button...yet also always knows the answers, helps her (high school) classmates, and is more mature than many of them. She definitely fits the "precocious" part, since she's a Child Prodigy who was smart enough to skip several grades and start high school at 10 years old.
• Black Butler: Ciel Phantomhive is a more dark take on the trope. The reason he acts serious and mature is the trauma he endured through losing his parents, and being kidnapped and tortured by cultists. He's now a driven, if jaded, Earl and owner of his own toy and candy company while he searches for the culprits in said torture.
• Hitsugaya Toshirou of Bleach also seems to suffer from this, except that a lot of people in the story do treat him seriously, because he's in a position of authority. Although he's Really 700 Years Old, he still suffers from this because the rest of the characters he works with are even older.
• Though he's 13 (and then 14), Riku from Blood+ looks younger. He also acts much older, too.
• Yukio from Blue Exorcist has forced himself into this to protect his brother. Though he is now a teen, he still qualifies as he is way more mature than the other characters of his age and in a higher position. Recent revelations has turned this into a Subverted Trope as Yukio is in no way actually mature or, to say the least, cute either.
• Syaoran Li from Cardcaptor Sakura, the 10/11-year-old rival-turned-love-interest who tries so hard to be serious and no-nonsense and mature (and for the most part does passably, keeping pace with Sakura in the capturing of Clow Cards in the earlier seasons and even living on his own in the manga continuity), but is still too small and cute for this to be truly effective, especially since he breaks out in a bright blush the second he's complimented or shown affection.
• Cells at Work! has the Platelets. As actual platelet cells are far smaller than most other cells, they are depicted as a team of small children that reconstruct areas of the town after injury. Although their small size can be an inconvenience, they are otherwise both highly-committed to and highly-skilled at their job.
• In D.N.Angel, there's the main character, Daisuke, and his rival, Troubled, but Cute Satoshi. Daisuke acts closer to the typical version, whereas Satoshi is a Wise Beyond His Years college graduate (despite being only 14).
• As a kid, Goku from Dragon Ball as well as his sons Gohan and Goten. Trunks from the main timeline also counts.
• Naota from FLCL, an entire series based around him trying to act adult (to be a good Replacement Goldfish for his big brother) and being mocked for lapsing into childish behavior.
• Fruits Basket: Hiro Sohma, being an actual middle schooler (Momiji is a high-schooler who looks like a middle schooler) who is clearly much more responsible than his mother and gets extremely offended any time he thinks someone is treating him like a child.
• Protagonist Niina from Hajimari no Niina: only 10, but with a very mature outlook on life as a result of being the reincarnation of a 16-year-old girl.
• Hanaukyō Maid Team. Taro is only 14 years old but tries his best to act in a responsible manner as head of the Hanaukyo family, including looking after the maids' welfare. Although the maids technically are under his orders, they at least influence what he does most of the time and sometimes (as in head Security maid Konoe Tsurugi's case) try to order him around.
• Haré+Guu: Haré has to take care of his drunken partying mom (who is only in her 20s) and as the straight man ends up being driven crazy by Guu's craziness.
• 13-year-old Wataru from Hayate the Combat Butler fits both the acting hard-working and responsible (he does pretty much run the head branch of his family's video rental franchise) and Mouthy Kid aspects of the trope. He doesn't have a big sister, although his maid Saki does fill the role.
  • If Hayate wasn't just a bit too old to qualify, he would probably be the poster-child of this trope. The levels of Moe that boy radiates are staggering.
• Shippo in Inuyasha is the equivalent age for a young kitsune and, despite being a crybaby at times, often takes delight in being more emotionally mature than Inuyasha himself.
• Lyrical Nanoha: Barrier Warrior Yuuno Scrya is a 9 years old archeologist and magic prodigy, the latter to the point of not even requiring a device to fend off Vita while he's analysing the magic prison spell they're in to find a way out.
• Usso Evin in Mobile Suit Victory Gundam , who is the second youngest Gundam protagonist at the tender age of 13 but also lived mostly alone and takes care of/is friends with the even younger 11 year old shakti. He hijacks a mobile suit mid-air singlehandedly for himself, and has to be blackmailed (in a way) to pilot the titular Gundam. In a aversion of this trope, people only make fun of him when he's being childish since whenever he's being serious... well, it's not funny.
• Negi Springfield of Negima! Magister Negi Magi was the basic polite version earlier on in the manga, while Kotaro Inugami is more of a Mouthy Kid. Both of them, however, are extremely capable on their own. Due to Genre Shift and liberal use of magical age-up pills, Negi has this trope more or less beaten out of him by various physical and emotional trauma by the midpoint of the story, although he hasn't been broken of the habit entirely.
• 11-year old Takashi from Nicoichi is not only adorable but as a result of his fine upbringing, also very responsible and can easily lead an independent life by himself.
• Ebisu's reincarnation in Noragami is this to a tee, having a strong understanding of Japan's economy and be empathetic to the needs of humanity while still being incredibly innocent and naive. Being a God of Fortune (specifically merchants) and have his Shinkis at his disposal, this shouldn't be hard for him.
• Boo from Now and Then, Here and There is adorable, loyal, protective, loving, responsible, mature, kind, innocent (but not for long), and realistic. He's also a child soldier, forced to fight in a mad king's army. The responsibility on his shoulders is staggering. Doesn't have a Cool Big Sis, but latches onto the series' Ensemble Dark Horse, even taking a bullet for him.
• Rebecca "Becky" Miyamoto, the protagonist of the wacky series Pani Poni Dash! is the adorable homeroom teacher of Class 1-C, who somehow graduated from the Massachusetts Institute of Technology (whose name she's barely able to pronounce, no less.) at the age of 10 and somehow received a job at Japanese high school soon after, and also has long multi-colored hair, an adorable cry when she's scared or hurt, and often teaches her students in a lab coat that goes all the way to her ankles^note after failing to be taken seriously in a gothic lolita dress in episode 2.
• Panzer World Galient: The Hero Jordy Volder is a surprisingly focused and capable fighter, considering the fact that he's merely 12 years-old.
• Mamoru Shimesu in Phantom Quest Corp.. He actually runs the company, the contacts, the finances, etc. while his boss Ayaka spends their funds on booze. He has a very stressful job.
• Pokémon Horizon: Mana is an 8 year old trainer who can fight with her Rowlett.
  • Raiha Uesugi of The Quintessential Quintuplets. She's well aware of her family's financial state, and she handles the cooking and housework (despite her young age, she's actually very good a it). Her brother Fuutarou comments that she often holds back on asking for things she wants, and he actually spends his first tutoring paycheck on taking her to an arcade simply so she can act like a child for once.
• Ken in Powerpuff Girls Z is one of these kids, and swings from being a Child Prodigy to being plain dorky, and the three Powerpuff Girls will often treat him like their cute younger brother (though they are not related to each other). Ken is an only child, living with his father (Professor Utonium) in Tokyo Laboratory, while his mother is an astronaut on the International Space Station.
• Jim Hawkings in Outlaw Star, who is clearly the more mature of the group between him and his "aniki" Gene.
• Revolutionary Girl Utena's Mitsuru Tsuwabuki, who is constantly bending to Nanami's every whim and taking care of her business, takes the desire to be treated like an adult to extremes — his rants during the Mikage Seminar and his duel with Utena border on the Ax-Crazy. "I want to become an adult and wreck the whole world! Wreck it!" "You become an adult by destroying other adults!" Or something to that effect.
• Rurouni Kenshin: Yahiko. Turns into more of a Cute Bruiser by the end of the series, to the point that he gets his own sakabato and a lot more responsibility in the epilogue.
• An oddly disturbing example is found in the titular protagonist of The Saga of Tanya the Evil, who is a ruthless self-serving Blood Knight and a very Creepy Child... and is also an adorable 10-year-old girl with blonde hair, azure eyes, and porcelain skin, who so happens to be a natural leader and powerful mage. Tanya sometimes uses this to her advantage, to get rival commanders to underestimate her, among any other uses she may need to act cute for, even if she loathes every second of it. On one memorable occasion, she wanted to attack an enemy munitions factory, but ethical guidelines required her to first announce on an international channel her intention of attacking the factory so civilian workers would have time to evacuate... but she broadcast her warning in the cutest voice she could muster, so everyone would think it was some kind of prank, and nobody evacuated, and she went ahead and blew up the factory with everyone still inside.
• Sailor Moon:
  • Shingo Tsukino is like this (when he's not slipping into Annoying Younger Sibling mode). He's highly intelligent, much more mature than his sister, and manages to charm quite a few ladies over the course of the series (both older and younger than him).
  • Chibiusa (Rini) is a sad version of this (when she's not acting like a Bratty Half-Pint); due to circumstances in her future, she has to grow up fast and act mature for her age.
• Sayonara, Zetsubou-Sensei has Majiru, Nozomu's nephew, who looks to be around 7-9 and sorta looks like a mini version of Nozomu. A bit snarky/mouthy, but still cute. He's not actually responsible for anything, but he acts very mature and sophisticated for his age. And he & Kiri Komori seem to be developing feelings for each other.
• While not part of one of the three main stories, Sekai-ichi Hatsukoi has Hiyori from the spin-off novel "Yokozawa Takafumi no Baai". Multiple characters, but especially Yokozawa himself point out several times that she is pretty mature for a ten year old. Justified since her dad is busy with work and a total clutz at home, so she is mostly responsible for the household. She has instances where she is a normal kid though (even though she greatly dislikes when people point it out).
• Ryuu from Snow White with the Red Hair is 12 years old, and a full-fledged court pharmacist at the royal palace the story mostly takes place in. He takes helping his patients fairly seriously, though they tend to see him as a Creepy Child.
• Sui Takishima, from Special A. Seeing as his big brother is basically perfect, it takes some persuasion by Hikari before Sui decides to actually do something. Once he does, however, he's almost as stuck up as Kei.
• Makoto from Wandering Son is only around 10 at the start of the story but is remarkably mature for her age, even compared to the other characters.
• Deconstructed in Yo-kai Watch with a yo-kai that makes a bunch of fifth graders put on airs. No one finds this behavior cute. It's considered annoying when kids try to act grown-up.
• Mokuba Kaiba from the (second) Yu-Gi-Oh! anime. A clear case of Bowdlerization, since in the original manga he qualifies more as an Enfant Terrible (but responsible, for that). His big sister is a big brother.

Comic Books

• Gabby of All-New Wolverine. She's the 13-year-old clone of X-23, a mutant like her with a Healing Factor and Wolverine Claws, trained to be a killer, and is ridiculously intelligent and very adult in how she reacts to the world. And then she turns around and gushes about making a costume for her pet wolverine both to protect his identity and because it's adorable. She also does her hair in barrettes, and wears big, chunky pink tennis shoes.

Comic Strips

• In an early comic strip from The Boondocks, Huey Freeman, a little black boy who is also a radical leftist activist, encounters a little old white lady. The old woman calls him adorable, but Huey is offended by this remark, and tries to rant about how he's not cute. But she ignores all of his points.

Fan Works

• Projection Quest gives us Mem, a Shikigami/Youkai made from [[Web Animation/RWBY Long Memory]]. She often reminds people that she is a thousands-year-old cane, but appears as (and acts like) a ten-year-old child who happens to know a lot about magic.
• In SlifofinaDragon's Sengoku Basara fanfics, Date Masamune and Sanada Yukimura's seven year old grandson Tsukitora (mothered by their son Masa and fathered by the late Oyamada Nobushige) has memorized some magic by Kyogoku Maria and is ungoing through some ninja training from Sarutobi Sasuke, and is shown to be quite cute in misakiyu's illustrations.
• Chara in TS!Underswap. They have a dry and sometimes sassy running commentary, take notes in their journal on the monsters they encounter along with illustrating the monsters with crayon drawings, and their sprite has open eyes but a neutral expression like the Human Child's, giving them an earnest, serious look at all times, even when sitting on a bench and childishly swinging their legs back and forth. It gets extra adorable if you equip the Cowboy Hat that Chara is under the impression makes them "look tough", since they wear it in the overworld too and make a point of carefully taking it off for naps and putting it back on when it gets knocked off their head.
• Fate Revelation Online:
  • The avatar that Ilya originally made for Shirou, deliberately designed to match his real life appearance when younger, makes him seem like this while it lasts.
  • Agatha, the NPC on the fifth-floor quest. She's based on Sakura Matou as a child and Kirito hands her over to Zolgen, who's based on Zouken. "Ellis Bell" brings her along when he gives Shirou a quest to move them to the 25th floor.

Film — Animation

• In Frozen II, when Elsa conjures ice toys for the kids in Arendelle, a little girl asks Elsa for a sextant (Elsa is surprised but manages to do it).
• The Boss Baby: Family Business has Tim Templeton's daughter, Tabitha, who is naturally smart and gifted and which is emphasized even further by her attending an ultra-advanced school.
• Tip from Home (2015) is quite mature for a young teen and often acts as the adult between her and her mother.

Film — Live-Action

• Morgan Stark from Avengers: Endgame is heavily implied to be a prodigious tech genius as, while most girls her age are playing with dolls and stumbling through a jumbo puzzle, Morgan explores the garage, plays with her mother's high tech battle helmet and enjoys watching her father work and otherwise proves to be a bit more advanced than most 4 year-olds, all on top of being tooth-achingly cute. Then again she is a child of Tony Stark, one of the smartest people in the Marvel universe so it was going to be a given.
• Kevin in the first two Home Alone films is brilliant but not too wordy.
• The Hunter: Sass wears pink in most of her scenes and is an earnest and innocent Cheerful Child despite some Wise Beyond Their Years moments.
• Jerry Maguire: Ray Boyd, the bespectacled 5-year-old son of Jerry’s work colleague, Dorothy.

Ray: Did you know the human head weighs eight pounds?

• The titular protagonist of Kid Detective (2020) had a detective agency as a child, which the adults around him thought was very cute.
• The Phantom Menace: Cute? Young? Super-Serious? Doesn't like to be treated like a kid? Family problems? Relationship with an older girl? Anakin Skywalker! Only in the first prequel, since Attack of the Clones takes place around ten years later and he's grown, well, quite a bit, like at least three feet.

Literature

• Older Than Television: The trope goes at least as far back to the detective novels of Edogawa Rampo (1894-1965, real name Hirai Tarou), whose protagonist Kogoro Akechi was frequently aided by the "junior detective" Yoshio Kobayashi. According to Wikipedia: "Kobayashi was written as a perfect young teenager who, some might say, had a strong 'dependency' on Mr. Akechi. Every time he appeared, he was either worried about Akechi's well-being or helping Akechi set the trap for criminals. On the numerous occasions that the boy was captured, Akechi swooped in for a timely rescue."
• Eoin Colfer's book The Supernaturalist involved a 'kid' called Ditto who was Really 700 Years Old — okay, in his early twenties — but as he was a naturally-immature adult he occasionally cracked.
• Eoin Colfer also brings us Artemis Fowl, who at the beginning of the series is a twelve-year-old evil genius who plans to rebuild the Fowl family fortune using fairy gold. Adults are always nonplussed at his mannerisms and speech patterns, and his mother wants him to act like a normal kid.
• Czeslaw Meyer of Baccano! deliberately tries to cultivate this image, despite being Really 700 Years Old. He claims he isn't used to being treated any other way.
• Markl from the movie of Howl's Moving Castle. He's generally more mature than his mentor, Howl, and yet still young enough to freak when a girl threatens to clean his room.
  • Better yet, Howl's child disguise in the new sequel, House of Many Ways, fits this trope to a tee, as not only does he speak with an exaggerated lisp, but also is described to be ultimately cherubic with golden curls, adorable puppy-fat, and a lot of lace. It's even more ridiculous when his reasoning for adopting a jailbait disguise is simply because he had a horrid childhood (or so he says, Sophie immediately denounces him as a liar) and he has every right to relive being six years old... only prettier. But because it is only a ruse, he manages to surprise the main character, Charmain, into speechlessness when he drops all pretenses and acts very adult and down-to-business.
• This Side of Paradise: As a child, Amory Blaine has a taste for fashion and was quite insightful as seen when he completely understands his mother when she was stressed and recognize her flaws unlike most children and once talked in reminiscent detail about famous musicians such as Mozart and Beethoven. His mother would end up bragging about how sophisticated, charming, and delicate he is to a room full of women who were in awe of it.
• Olver from The Wheel of Time fits this trope in-universe despite being described as downright ugly in the books. It probably has to do with when he follows his Big Brother Mentor Mat around to watch his back and tries to mimic the Warders.
• In One Cool Friend, Elliot is a sharply dressed and bright little boy with impeccable manners, who's not interested in the exhibits at the aquarium that are popular (and crowded) with children, but he still has a childish innocence that excuses him from stealing an animal from an aquarium exhibit.
• Lessons in Chemistry: Madeline is humming Bach concertos and reading Dickens at the age of kindergarten, but she takes care not to stick out too much. She even takes it upon herself to dig up her late father's family history.

Live-Action TV

• Sheldon Cooper in The Big Bang Theory was certainly a precocious child, skipping middle and high school practically altogether and going straight to university aged about twelve. From the recollections of his mother and others, adorable was, however, debatable and a matter of opinion. He would appear, in context, to have had a lot in common with Ruth Lawrence. (see Real Life, below.) The spin-off series Young Sheldon expands on this and gives us a picture of the life and family of Sheldon Cooper, aged nine.
  The good Lord never gives you more than you can handle. My other two children were as dumb as soup.
• Nicki Reagan on Blue Bloods is in middle school when the series started, but dresses and behaves like a thirty-two year old. She isn't cowed by any of the Reagans, regardless of age, and seems to view herself as the matriarch of the family.
• Doctor Sweets of Bones. He's the youngest member of the team and cannot get himself taken seriously because of it, tends to lapse into Sophisticated as Hell mid psych-babble, looks up to the two main characters as Parental Substitutes, and is all around dorky but cute.
• Lyanna Mormont from Game of Thrones. Lyanna is the young Lady of Bear Island and has acted as the head of House Mormont of Bear Island ever since the death of her mother, Maege Mormont. Incredibly stern, stoic, and totally 100% adorable.
  Lyanna Mormont: We are not a large house, but we are a proud one, and every man from Bear Island fights with the strength of ten mainlanders.
  Davos Seaworth: If they're half as ferocious as their lady, the Boltons are doomed.
• Girls5eva: Parodied with the concept of the "New York lonely boy": a young boy who, because he's an only child, makes friends with doormen, enjoys going to the bookstore, watches documentaries, listens to NPR every day, and gets niche hobbies.
• French sitcom Les Filles d'à côté gives us Wendy, the six year old daughter of central character Fanny, whose role in the series is to be precocious, adorable, and to Lampshade where Maman and her two adoptive tantes get it wrong.
• Let the Right One In: Eleanor seems this way to people unaware of her true age, acting and speaking older than the girl of twelve she apparently is. That's because she's a vampire who's chronologically twenty two.
• Tim and Heather's youngest daughter Sophia astounds her parents with her intelligence in Life in Pieces. Tim has a hard time reconciling the fact that his daughter's so smart yet hadn't figured out that Santa Clause, the Easter Bunny, and the Tooth Fairy weren't real until someone told her.
• Ned's Declassified School Survival Guide: Claire, or, as she always introduces herself, "Claire Sawyer, Future Lawyer," is a middle school student who, as her name indicates, already has serious plans to become an attorney. She wears a pencil skirt and blazer (or, occasionally, a power suit) to school every day, carries a briefcase, and has business cards, which she passes out as she represents her classmates in "cases" against each other or the faculty. Claire very much falls into The Comically Serious, with her maturity and stoicism being both weird and endearing.
• Odd Squad: Nearly every single employee of Odd Squad fits the trope to a T. They're children, but are more sane, more intelligent, and more reasonable than the idiotic and sometimes criminal adults of the world.
• Resident Alien: Sahar is remarkably responsible and serious for her age, helping Max in his bid to expose Harry as being an alien. Though she does act like a kid as well, it's part of her charm.
• Shake it Up:
  • Flynn Jones. He handwaves that he's "the only responsible person around here", and even got a model to like him, saying he's adorable.
  • Flynn's friend Henry Dillon: he's a Child Prodigy and Insufferable Genius but is much more naive than Flynn.
• She's Gotta Have It: Opal's daughter Sky is very well-spoken, sounding like a little adult although she's only seven or so. She lampshades it, even using the word for herself. Nola finds her charming and is amused when she chides her mom over eating meat, as she's a vegan.

Theatre

• Hamilton:
  • Peggy Schuyler in "The Schuyler Sisters" who manages to bring up that the upcoming war isn't going to be a bed of roses; that strife will come to American shores and their father may end up in danger by wanting to join the fight. Angelica and Eliza override her with optimism about how the revolution means new ideas and excitement, but Peggy makes quite a good point.
  • Philip Hamilton as well; he concocts a rather cute rhyme for his ninth birthday and is studying French and musical scales with his mother.

Video Games

• The Ace Attorney character Pearl — despite being eight — speaks in a formal, verbose manner, and rarely takes anything lightly. This comes of spending her whole life in the archaic Fey compound, isolated from everyone but her (much older) family members-one of whom was deliberately grooming Pearl to be the next Fey leader. Still, she has a child's changeable emotions, naivete, and tendency to Squee.
• Carl Clover from BlazBlue, despite being just a kid, is a vigilante that has captured many criminals with the help of Nirvana. He always talks in a very professional matter and dislikes being treated as a kid. His attitude does hide a rather vulnerable side of him, though.
• Disgaea:
  • Taro of Disgaea 2 is a fairly straight example, though a bit of a Cloud Cuckoolander. He's sweet and more mature than one would expect and is absolutely adorable. He's not taken very seriously by anyone, though.
  • There's also Emizel in Disgaea 4, although extremely young (for a demon), he's attempting to fill the role of Grim Reaper for his father. People don't take him seriously at all, but that's more because he's terrible at his job than his age. He's also clearly being played for cute, thanks to his bow tie and shorts.
• Dragon Quest V: During the first act, the main character is a cute but serious, committed and responsible kid who has been travelling with his father all over the world to find his disappeared mother. His son Parry is only an eight-year-old kid, but he has to deal with the responsibilities of being a prince, looking for his disappeared parents, and being the Chosen One. Parry's twin sister Madchen tends to take her role as a princess even more seriously.
• Final Fantasy:
  • Shinra from Final Fantasy X-2. He's a kid genius and often the least emotional of the Gullwings. A bit unusual in that he is wearing a suit that covers him completely, including his face.
  • Hope of Final Fantasy XIII becomes this with character development. Although played for cute all along, he's a Bratty Half-Pint at game open, but he's become very mature for his age by the time the game ends.
• Fire Emblem:
  • Rolf from Fire Emblem: Path of Radiance certainly qualifies often putting a tough front despite being very sensitive and sweet.
  • Sothe qualifies once we learn his backstory: he's been looking after and protecting Micaiah for years despite being younger than her.
  • Both genders of Kana qualify for this in Fire Emblem Fates, though the Male qualifies for this slightly more. Due to growing up in the Deeprealms, they hate being seen as a child and work to contribute to the army in the best way they can... while simultaneously still being a Daddy's Girl / Momma's Boy at the end of the day, with a major need for affection and huge imagination like other children.
  • Fire Emblem: Three Houses introduces Lysithea von Ordelia. The youngest student in the academy? Check. Incredible magic skill? Check. A hardworking, responsible personality? Check. Putting on a mask of maturity and outward sternness? Check. Occasionally indulging in kid-like antics such as stuffing herself with sweets? Check. Dislike of being called a child? Check.
• Golden Sun:
  • Another adorable and confusing nerd is Rief from Golden Sun: Dark Dawn. While his age is ambiguous, his appearance, voice squeaks, and behavior all suggest that he is on the young side of Golden Sun's traditional Kid Heroes.
  • Though she didn't get much screentime or character development, Himi probably also qualifies due to her precognitive powers giving her a wealth of knowledge to draw from, and she's expressly described as "not much older" than the little kids playing in her hometown.
  • Thirty years prior to them in Golden Sun: The Lost Age, Eoleo was a dorky-looking toddler too young to talk, but not too young to fake crying to throw off attention, experiment with his new Psynergy powers, break his father out of prison, and reason that Felix can solve the traps in Treasure Island that had the pirates stumped. And when addressed telepathically through Mind Read, he had a perplexing case of Little Professor Dialogue.
• Pierre from Harvest Moon would be an almost archetypal example, between his cute, childish appearance, and his mature, sophisticated behavior... Except for that fact that no-one ever fails to take him seriously, even though he looks younger than every other character that's not explicitly a small child.
• Riku from Kingdom Hearts was extremely perceptive and insightful at five years old, able to immediately spot an off-worlder and give Sora outstanding advice about a complicated issue.
• Culotte of La Pucelle. He's generally much more mature than his Promoted to Parent big sister, and hates being treated like a child. He's also adorable.
• The Legend of Zelda:
  • Link definitely qualifies. None of his reincarnations are older than 16, some as young as 12, but he has no trouble taking the whole "fate of the world" thing in stride. Same goes for the younger Zeldas, who are always preoccupied with the protection of Hyrule even if they're not old enough to rule it yet.
  • Pamela in The Legend of Zelda: Majora's Mask is an adorable little girl with Youthful Freckles who locks her father in the closet during his Slow Transformation into a Gibdo and refuses to open the door for anyone to prevent the Gibdos outside from taking him away. After Link returns him to normal, she says she'll try to convince him to leave the dangerous Ikana Canyon go back to Clock Town.
  • Riju from The Legend of Zelda: Breath of the Wild. Losing her mother and taking her place as Chief of the Gerudo at such a young age forced her to grow up fast, yet she does a remarkably good job of it, and she also displays a knowledge of the Lost Technology of the Sheikah almost as good as that of the Sheikah themselves. She still plays with stuffed animals, though, something she'll be embarrassed about if you catch her doing it.
• The professor's boy assistant Luke Triton from Professor Layton. Acts mature? Check. Isn't always taken seriously? Check. Played for cute? So very much check.
• Laphicet from Tales of Berseria, once he's allowed to break out of his shell and emote, is quite curious about the natural phenomenon of the world. The kid risks his life for a compass!
• Genis from Tales of Symphonia qualifies very much. He's dang mature and can even be a Deadpan Snarker when he feels up to it.
• Ken Amada from Persona 3 seems like a typical one of these at first. He acts unusually mature and serious, and isn't taken all that seriously by the older party members. However, it's later revealed that he joined SEES so he could exact revenge on his mother's killer. After which point, he becomes a retroactive Deconstruction, as all his earlier attempt to appear mature can be viewed as unhealthy coping mechanisms, and even by Persona 4: Arena Ultimax, where he's in his early teens, Ken laments that his trauma prevented him from having a real childhood.
• Bugsy from Pokémon, one of the youngest Gym Leaders in the series, but also one very dedicated researcher. And while he's always deep into his research (bug Pokémon in the game, ruins in the manga), he sometimes shows a very child-like enthusiasm about what he likes. It also adds to his charm that he's often confused for a girl.
• Caillou from Recettear: An Item Shop's Tale is a good example of this trope. He's a powerful mage, running a serious investigation, but inside he's still just a kid who can't resist candy.
• Kiel from Rune Factory 4, though he's apparently old enough to marry and thus technically not a "child" in the strictest sense. He certainly looks it, though, and is a bit of a Ditzy Genius, reading tons of books but still being naive enough to take everyone at face value, even people he knows are practical jokers.
• Sonic the Hedgehog: Silver the Hedgehog, despite being 14 years old, can be considered this too, as he's a young boy who is naive and cute-looking, but repeatedly tries to stop a Bad Future.
  • Miles "Tails" Prower from Team Sonic, Cream the Rabbit from Team Rose, and Charmy Bee from Team Chaotix, where in the manuals of Sonic Heroes list their ages to be younger than 10 years old. They however remain cheerful and idealistic in their adventures to stop Dr. Eggman, befitting their age.
• Alfred, the adorable younger brother to Maya and a member of the rival gang of Drifters in Wild ARMs 3. He's clearly more mature and level-headed than his impulsive, treasure-seeking sister.
• Jr. from the Xenosaga series plays with this trope. He's certainly set up to be a typical precocious child, acting far more mature than his tender years would suggest. However, he's generally taken seriously by everyone he meets, and we later learn he's actually pretty immature for his age, seeing as how he's chronologically in his thirties.
• Yes, Your Grace: Princess Cedani is young enough to expect things to turn out like they do in fairytales, and spends the game adopting various animals to train them as agents to help her father in his job.

Webcomics

• Bram & Vlad: Bram has alrady written four scientific monographs, and he is a precocious 13-years-old genius who inspires some respect. When he is not being a huge dork.
• The doctor that treats Shine in NEXT!!! Sound of the Future is a Kaai Yuki, an android modelled after the appearance and mannerisms of a little girl, and she tries her hardest to be a stoic professional. She also happens to be a massive fan of Miku, with a scrapbook full of autographs and photos of her with some of the top Mikus in the industry, which moves her to waive Shine's medical bill and ask her to sign her book as well.
• One-Punch Man: Child Emperor is one of the world's top superheroes, and for a good reason: not only is he extremely intelligent, capable of creating all sorts of mechs, but he's also really skilled in hand-to-hand combat when it comes down to it. He's also a master strategist and, ironically, one of the most mature members of the association, despite being one of the youngest. All said, he still has his childish side: hates being treated like a child, can get cocky about his status, gets grumpy whenever he has to get out of school to do hero work, and he's constantly snacking on a lollipop, even in battle.
• Tower of God: Twenty-Fifth Bam is a cute young boy with a talent to befriend people and who really wants his best friend back. He is very diligent, honest and compassionate, extraordinarily humble and talented. Jue Viole Grace on the other hand…

• The Autobiography of Jane Eyre: Adele Rochester works all the time for her futile homework assignment (though she's fond of learning), knows all about art forms of the twentieth century, speaks French, uses Latin in her tweets, has ballet/fencing/opera lessons, plays puzzles competitively, frequents Advanced Marine Zoology courses, went to an Applied Physics boot camp and is a Scout girl. She's very responsible, knows what she wants, and Jane says she kind of tutors herself. As is typical for precocious children, her family situation is complicated, to put it mildly. She surely knows a lot, but sometimes she has troubles to contextualize it and can come off as a weird kid. She's very nice to Jane, who is concerned about her being lonely and neglected by her father.
• Both the titular cloud and the girl she befriends in Cloud.

Western Animation

• Flip Chan in The Amazing Chan and the Chan Clan. He acts responsible for Mimi, Nancy and Scooter when they're out on the case, and is quite a cute kid.
  • Mimi and Scooter are no slouches in the cute department, either. Mimi usually pushes her authority on Scooter, who wants to launch head on into the episode's unsolved crime.
• Arcane: Powder, the girl who would become Jinx years down the line, starts out as an adorably sweet, if somewhat naïve child.
• Bad Dog has Little Vic, the youngest member of the Potanski Family, and the one with whom Berkeley has the closest relationship.
• In the first episode of The Boondocks, Huey Freeman attends a garden party full of rich white guests. Huey tries to talk about his political conspiracy theories, hoping that it will offend their conservative sensibilities. But instead he gets praised for being such an intelligent and articulate child, which annoys him to no end.
• Penny Sanchez of ChalkZone, a Bespectacled Cutie, Cute Bookworm, and the hero's best friend. She has been known to give lectures on quantum physics, as well as being the best student in her class.
• Kam Chin from Class of 3000 tries to act mature and refined, but he's still the youngest of the kids (along with Kim, his twin sister) and is ultimately Not So Above It All when it comes to the zanier aspects of the series.
• Dotty from Hanna-Barbera's 1976 series Clue Club is a pigtailed 13-year old cutie who is highly versed in forensics and technology. She operates from home base partly because she's needed there and team leader Larry says she's too young to join the others. Not that it's stopped her from doing so.
• Most of the male KND Operatives in Codename: Kids Next Door ironically do quite a few things you'd expect adults to do (usually when non-villain adults aren't around to notice) and yet the show still maintains the fact they're kids, given the KND is a military organization consisting entirely of children (with some areas in science, politics, etc.) so that would in ways make sense. Oh, and the boy KND Operatives are really adorable, just ask their fangirls.
• Gilbert Troodon from Dinosaur Train is very responsible and sensible, despite being no more than eight years old. He often helps his uncle run the Dinosaur Train.
• Doug: Doug Funnie. He's very responsible, though still acts like the average eleven-year-old. He's also one of the so-dorky-they're-cute types.
• Amberley of The Dreamstone has shades of this at times. She's noticeably more intelligent than Rufus and unlike him, seems to hold down her job rather competently. Most episodes have her act as a leader or strategist of the two. At times however, her bratty temper flares and she proves rather rambunctious.
• Edd "Double D" from Ed, Edd n Eddy, to the point of cleaning his friends with napkins and occasionally scolding their immature behaviour as if he were their mother.
• Mac from Foster's Home for Imaginary Friends. He's only 8 years old, but is intelligent, usually pretty mature for his age, has his childish moments, and is downright adorable.
• Dipper Pines from Gravity Falls. At twelve, he's the Only Sane Man, already fancies himself a paranormal investigator and is repeatedly trying to befriend the cool older kids, particularly his crush, Wendy. A mild Deconstruction, as his arc near the end of the series is learning not to rush adulthood so much (in contrast to his twin sister Mabel, who becomes afraid of growing up).
• The titular character of Hey Arnold! OWNS this trope. Acts as if he's preoccupied with responsibility, once had a crush on an older girl (well, she was only two grades ahead), and one of the most adorable kids on the show.
• Invader Zim has Dib. Only eleven years old but is one of the smartest humans in the show. With feats like hacking government and alien networks with ease, being able to spell while still just a baby... list goes on. He's also one of the few heroic characters on the show and his natural fascination with space is adorable.
• Brainiac 5 in the Legion of Super Heroes cartoon was made into this kind of (pre-)Teen Genius for the first season, in contrast to his snarky Insufferable Genius characterization in recent comics.
• Orel Puppington of Moral Orel, he's the only one in a corrupt town that has no ill intentions and genuinely loves God and (most) everyone in town.
• Spike, the iconic baby dragon of My Little Pony: Friendship Is Magic, is at least five years younger than the mane cast, but more often than not acts as a Straight Man to their antics, usually showing just as much (if not more) maturity and understanding of a situation. However, he often acts his age, usually when jealous or overeager to show results. Then again, this is a franchise where the adult characters constantly jump between holding down jobs and excitedly playing Pin-the-Tail-On-the-Donkey.
• The eight-year-old Kate from Pelswick almost acts like the mom of the house, doing such things as trying to manage her father looking for a job and her older brother thinking about higher education.
• A lot of characters from Ready Jet Go! don't exactly act their age. Special mention goes to Mitchell Peterson, who is little but made an exact cake replica of Saturn V in one episode.
• The appropriately named Precocia Holiday from The Roman Holidays. Having Pamelyn Ferdin as a voice certainly doesn't hurt.
• Tricks from Scruff is a Talking Animal version of this trope, being a young Border Collie pup with an easygoing, smart, modest but playful personality.
• Peedee Fryman from Steven Universe. In his debut episode he's gotten a job in his family's restaurant to impress his father, only to get depressed that he's been stuck with the lame mascot position. In subsequent episodes he's been promoted to deep fryer and seems much happier. His older brother Ronaldo, on the other hand, slacks off and has Peedee cover for him.
• TaleSpin has Kit Cloudkicker, Baloo's right hand bear who, despite only being 12, is a very skilled navigator and has a vast knowledge of planes.
• Badass Adorable Omi from Xiaolin Showdown acts very mature for his age and takes his job as a monk seriously. Still, he can be interested in fun things he never experienced, like video games and basketball and his lack of social skills makes him naive.
• Yugo from Wakfu is one of the most emotionally mature, yet earnestly childish examples of this trope.
• We Bare Bears has Chloe Park, a preteen girl who is already in college, studying biochemistry. And while she's very smart for her age, that makes her have an easier time making friends with the bears than with college kids. She's also prone to have lapses in judgement appropiate for a child her age.
• Robin from Young Justice (2010), though he's thirteen and technically juuust outside of the proper age range. But since he's the youngest and the most experienced crime fighter of the six main characters, the effect is pretty much the same. See also: Billy Batson.
