* Buddy in ''Film/{{Elf}}'', in which most of his actions are naive, ''adult child''-related, not elf-like. In fact, he's just about an opposite to all of the other elves in the film.

Related to, but not to be confused with, ManChild. Not to be confused with OneOfTheBoys or OneOfTheGals.

* PlayedForLaughs on ''WesternAnimation/YoungJustice,'' when [[ComicBook/{{Shazam}} Captain Marvel]] is tasked with mentoring the Team. He adores them and repeatedly tries to hang out with them on missions and social events, while they treat him as either an intrusive spy from the Justice League or, at best, the way most teenagers would treat a grown man who acts like a ten-year-old. The joke, of course, is that Captain Marvel ''is'' a ten-year-old HenshinHero who transforms into [[OlderAlterEgo an adult superhero]], but neither the Team nor most of the Justice League know that.

** Compared to the rest of Ash's Kalos mon, Goodra remained as {{Adorkable}} and playful as it was as a Goomy, which lends to several characters recognising it as such just from behaviour. When it reunites with it's childhood friend, Wooper, it goes into an excitable fit, despite now being over ten times it's size.

** Ash's Lycanroc in the ''Sun and Moon'' series tends to act as much like friendly and energetic puppy as it's Rockruff form and even has a {{Friendly Rival}}ry of sorts with the unenvolved Litten.

%%* Much of the cast of ''WebVideo/ShinyObjectsVideos'', especially visible in "On The Couch".

* Kei's mom in ''Manga/HououGakuenMisoragumi''. She's also considerably ignorant to go along with her immaturity.

* Soos from ''WesternAnimation/GravityFalls'' is still into things like laser tag and getting pizza at [[SuckECheeses Hoo-Hah Owl's Animatronic Jamboree]], and is frequently up for any fun Dipper and Mabel get into, whether it's investigating the supernatural or bedazzling his shirt to make him a human disco ball.

* Invoked in an episode of ''WesternAnimation/RockosModernLife'' where Mr. Bighead suffers a midlife crisis and attempts to get in on the fun with Rocko and his friends.
* Jake from ''WesternAnimation/AdventureTime'': okay, he's a dog, but he's twenty-eight in dog years. His best buddy is his teen-aged step-brother Finn.

* Jake from ''WesternAnimation/AdventureTime'': okay, he's a dog, but he's twenty-eight in dog years. His best buddy is a fifteen-year-old.

--->'''Pinkie:''' Too old for free candy? Never!

%%* Soos from ''WesternAnimation/GravityFalls''.

%%* ''Series/MrBean'' has been described by Rowan Atkinson as being a fully-grown man with the mentality and maturity of a 9 year old boy.

* {{Pee Wee Herman}}, obviously.

* ''VisualNovel/DanganRonpa'' has Yasuhiro Hagakure, who's 20 years old while the other main characters are high school students (he was held back a few years). Despite being the oldest of the students, he's probably even more ditzy and immature than the rest of them.

%%* Mrs. Miyaji, and most of the other adults in ''{{FLCL}}''.

%%* The modern take of the ''ComicBook/{{Shazam}}'' Captain Marvel with the superhero keeping the personality of the boy, Billy Batson, in his Marvel form and the same going for the modern take on his sister, Mary. Captain Marvel is an interesting example of this trope, both because he's a literal example and because Billy is [[WiseBeyondTheirYears very mature]] for a kid his age, which is why most people don't catch on to his being an adult child. This also means, that depending on the situation, someone could meet both the Captain and Billy, and come away with the impression that Billy is more mature.

* Eldon from ''Literature/TheColdMoons'' is a simple, almost childish adult. His low-maintenance personality and active imagination makes him great with cubs. After he steps down as the SketchySuccesor of the badgers, he becomes the caretaker of the cubs along the journey to Elysia. The cubs follow Eldon without any trouble.

* Jack Rakan in ''Manga/MahouSenseiNegima'' doesn't count himself among the main cast, but he's managed to become a major player in the kid/teen-filled Ala Alba. Keep in mind, he's old enough to be considered a BadAssGrandpa. The other Ala Rubra members (Eishun, Albireo) by contrast had a sense of aloofness to the main cast.

** ''Film/X2XMenUnited'': Nightcrawler was excluded from the planning session along with the younger X-Men.

* Irabu-sensei from ''Manga/KuuchuuBuranko'' is this. His Adult and especially Stuffed Animal personas act childish, silly and borderline crazy awesome (for normal and average people around him), but when he switches over to his ''Child'' persona, he acts serious and like a decent psychiatrist.

%%* The three hosts of ''TopGear'' can get like this, especially when they're in one of their competitions and start messing with one another, although Jeremy Clarkson is usually the quickest to start acting like this with the least amount of prompt.

* Ilulu of ''Manga/MissKobayashisDragonMaid'' is stated to be the same age as Tohru, roughly the dragon equivalent of a sixteen year old. However, due to past childhood traumas, she's emotionally stunted and she's shown to vastly prefer the company of younger children such as Kanna and her elementary school friends. She ''can'' be mature, but even then her preference for the company of kids comes through. Her choice of job, part-timing at a candy store, allows her to contribute to the household, as Tohru insisted she do, but also means she can work in a place children often visit.
