* Mark, the host of ClassicGameRoom, to the point where he has a separate channel devoted to reviewing toys.

* Arguably Homer from The Simpsons.

* Yukari Tanizaki from ''{{Azumanga Daioh}}'' could be considered to embody this trope, although she is still treated by her students with respect due to being a teacher (by everyone except [[JerkAss Tomo]]). A respect she abuses without shame.

* Howie Gordon from the American version of BigBrother.

* ''ShinMegamiTensei: DevilSurvivor2'' has Joe play this to a "T."

* Eva from ''SupernormalStep''.
* Rayne Summers from ''LeastICouldDo''.

* Ethan [=McManus=] of ''CtrlAltDel''.
* To an extent, Oggie from ''Webcomic/GirlGenius''.

* Jack Rakan in ''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.

* Rigby from ''RegularShow'' acts less like a mature 23-year-old and more like hyperactive 10-year-old.
** So, he acts like an ''[[CaptainObvious im]]''[[CaptainObvious mature 23-year-old]].
** Mordecai too, to a lesser extent. He's a lot more level-headed and less impulsive than Rigby, but just as eager to slack off and do childish things.

A subtrope of {{Manchild}}. Not to be confused with [[WiseBeyondTheirYears a child who acts like an adult]].

->'''Scott''': "It feels like we're alone in the world. No grownups! It's like ''Series/TheTribe''."\\
'''Kim''': "Scott, we '''are''' grownups. And I have no idea what ''Series/TheTribe'' is."\\
'''Scott''': "I don't think I'm ready to be a grownup."
--> -- ''ScottPilgrim's Finest Hour''

* Philip J. Fry from ''{{Futurama}}'' has since the beginning of the series been the epitome of Generation X (or Y perhaps): A big 20-something man-child. He plays video games, watches TV, drinks soda by the gallon, does crazy things off of dares, and has no ambition in life except for one...love. He's that flat mate that you knew who just can't seem to truly grow up (...and is often fully aware of it. Refer to his one ambition for why this is a source of gloom for him often), but at least he's cool to hang out with.
** The new season reveals that Fry is 35. Adult Child, ho!
** Actually, he might be as old as 31 since in one episode, he and the Planet Express crew [[spoiler: were affected with chronotons that reversed their aging and then they negated the effects by going into the Fountain of Aging.]] And they, sans the Professor were [[spoiler: reborn in the series's revival.]]
** Let's not forget that [[spoiler: Fry is his own grandpa]] and that caused genetic damage, which caused his brain to develop abnormally.

* ''WebOriginal/TheAngryVideoGameNerd'' (James Rolfe)

** Also, TheNostalgiaChick's ''MyLittlePony'' episode showed that her best friend [[ButtMonkey Nella]] still has (and plays with) her my little ponies. Things got dark pretty quickly though, we only see a bit but one is a hooker with a heart of gold, the stranger looking ponies are treated as freakish abominations, and there is at least one death (implied to be a suicide).
** Most of the ChannelAwesome crew fits this to one degree or another. [[WebOriginal/AtopTheFourthWall Linkara]] stands out, given that he collects Power Ranger toys.

'''Kim''': "Scott, we '''are''' grownups. And I have no idea what ''TheTribe'' is."\\

* Lou's mom in the French comic book ''Lou!'' In addition to being a video game addict, she generally tends to behave in a more immature way than her 12-year old daughter.

* Ernest Worrel in the Ernest films, especially in ''Ernest Scared Stupid'' in which none of the parents believe him about the disappearances of their children or the troll.

* Done very creepily with Pearl in ''The Changeling''.

* Ever since his transformation, Ratfist's [[spoiler: severed tail]] has been an embodiment of his id, and will spit out every last thought that crosses his mind, conscious or otherwise. Often this hints that he never really grew up (which may explain why he's prancing about in a costume fighting crime); sometimes the hints are fairly benign ("I want to eat an entire pizza") and sometimes it suggests that ''kids can be really fucking terrifying''.

* The author of ''Hyperbole and a Half'' according to herself in [[http://hyperboleandahalf.blogspot.com/2010/06/this-is-why-ill-never-be-adult.html this entry]].

* Scott Pilgrim from the ScottPilgrim fits this He's 23 years old and doesn't like taking any adult responsibilities He even Dates a 17 year old girl who's more mature then him.

The AdultChild shows up most often in anything aimed at younger audiences, where they are PlayedStraight so as to be more appealing to kids. When PlayedForLaughs, it's to show an immature or silly character.

See also WiseBeyondTheirYears. The difference between this situation and WiseBeyondTheirYears is the AdultChild is rarely treated as any kind of authority; because of their casualness they often do not even earn special respect.

** However, it's highly likely that [[spoiler: Midori might have ''faked'' at least half of her AdultChild tendencies, using it as ObfuscatingStupidity.]]

** Arguably, ''every'' adult in Dimmsdale is an AdultChild to some degree. Timmy's parents are just the ones we know the most of.

Contrast WiseBeyondTheirYears. The difference between this situation and WiseBeyondTheirYears is the AdultChild is rarely treated as any kind of authority; because of their casualness they often do not even earn special respect.

* There's more than an element of this to Homer [[TheSimpsons Simpson]], particularly in the episodes which require him to be with the kids without Marge around. Much of Homer's strife in life could easily be seen as having come from the fact he's really an overgrown little boy...forced to deal with the harsh adult world. Although this has been [[{{Flanderization}} extremely exaggerated]] in later seasons, even earlier on this was a defining characteristic of the Simpson patriarch. Many other characters (primarily male) in the series have a similar trait:
** Same goes for Otto, the school bus driver:
--->'''Otto:''' (when Bart reveals that he will try to jump over a gorge on a skateboard) As the only adult here, I feel I should say something... (after a beat) ''COOL!!''
** Chief Wiggum is similar to Homer in that he's pretty much an adult child as well. He often shows childlike enthusiasm for all sorts of things, argues like a child, when he's friendly he does it in a very child-like way, and even his more corrupt personality traits don't seem malicious but rather more akin to irresponsibility. He's pretty much the little hall-monitor child stuck in a man's body.
** Large and burly Barney Gumble in his better years often showed traits of childlike behavior and sensitivity, even when not ''quite'' as drunk. Perhaps that's why he's an alcoholic...
** Milhouse Van Houten's father Kirk is pretty much Milhouse at age 40+.

* ''FamilyGuy'''s Peter Griffin, especially in recent years (and of the [[PsychopathicManchild rather deranged variety]]). Homer Simpson at least seems like an overgrown adolescent, while Peter often seems more like a five-year-old.
* The Earl of Lemongrab on ''WesternAnimation/AdventureTime'' is an interesting version of this. Physically he's eighteen at the youngest, but because he was born in a laboratory, he's only about one year old chronologically. He acts like a bratty little kid trapped inside the body of an adult, mainly because he IS a very young brat who happens to be an adult, too.
* ''SpongebobSquarepants'' and Patrick Star.
** This was actually the basis of [[TheMovie the Spongebob Squarepants Movie]], where Spongebob and Patrick try to prove they're not kids. In the end, though, they come to accept that they are kids.
* Coach [=McGuirk=] on ''HomeMovies'' hangs out with Brendon a lot and is pretty much on the same level maturity wise.
* [[TheFlintstones Fred Flintstone]], and on some occasions, Barney Rubble, too.
* Due to awesome CharacterDevelopment, Chris almost became one in the second season of ''WesternAnimation/TotalDramaIsland.'' He started whining a lot more ("I can't feel my AAARMS!!") and bending the rules so he could get his way much more often. ("Oh, I'm sorry, are YOU the host of the show!?") This has died down in season three because he and Hatchet are on good terms again.

* Like modern comic book interpretations, Captain Marvel from ''WesternAnimation/YoungJustice'' comes across as a ten year-old kid, despite having the physical strength, body and wisdom of someone much older. Of course, that's because he really ''is'' a kid. His Billy form actually can come across as more mature in comparison.

* DougWalker seems to fit this trope.
* ShigeruMiyamoto, creator of [[SuperMarioBros Mario]] and TheLegendOfZelda.
* [[http://www.pixyland.org/peterpan/ Randy Constan]], Peter Pan impersonator/cosplayer/lifestyler and self described "Eternal Child".
* Russell Howard during a lot of his stand up shows, if not all of them. Such as when he talks about fatherhood with "I can't wait to be a Dad me, of course I'm not ready yet I'm still scared of the dark.".
* Karl Pilkington, whose childlike thoughts and constant reminiscing of his own childhood are a source of much amusement in ''TheRickyGervaisShow'' and ''AnIdiotAbroad''.
* Wolfgang Amadeus Mozart as an adult. As a child, he behaved like an [[WiseBeyondTheirYears extremely intelligent and knowledgeable adult]] to an extent that was considered [[CreepyChild somewhat unnerving.]]
* The famous [[http://es.wikipedia.org/wiki/Romualdito_%28animita%29 "Romualdito"]] was apparently this when alive. (Possibly due to brain damage, according to some.) He was stabbed to death next to the main train station in Santiago, UsefulNotes/{{Chile}}; now he's known as a famous "miracle maker".
* There's a creepy example that's played straight. How straight, you may ask? Well, how about a guy who isn't acting like a child, rather act like [[http://www.youtube.com/watch?v=fqEDIFfy4Yg A BABY]].
* The late Kim Jong-il's palace contains a waterslide and pool. No, ''[[http://www.nkeconwatch.com/nk-uploads/elite1.JPG really]]''.
* Christian Weston Chandler, creator of {{Sonichu}}.

* A [[http://www.youtube.com/watch?v=38YWB8iX7OY recent ad]] by the South African company Nando's depicts [[UsefulNotes/{{Zimbabwe}} Robert Mugabe]] having a water pistol fight with MuammarGaddafi, making sand angels with Saddam Hussein, pushing P.W. Botha on a swing, and similar activities with other dictators. [[CrossesTheLineTwice Yes, really]].

** ...as for Konata herself, she admitted her thinking is not unlike that of a second grader. [[OlderThanTheyLook Neither are her looks]].

* Megumi "Nodame" Noda from ''NodameCantabile'' can respond in a ''very'' childish way to the events around her, much to the dismay of her love interest, Chiaki.
* Ran from ''KazemakaseTsukikageRan'' regresses into childlike behavior whenever she drinks sake--or sees elephants--to a degree even her partner Meow finds incomprehensible.
* Apachai Hopachai from ''KenichiTheMightiestDisciple'' pairs this with being the largest character in the story. His behavior is complete with spouting nonsense words, a complete lack of self control, and the handwriting of a 7 year old. Thank goodness he is good at fighting and teaching Muay Thai at least (if he decides goes easy, that is - in this case, "going easy" is just beating Kenichi until he is somewhere around half-dead).

* ''Manga/OnePiece'''s Monkey D. Luffy often behaves like a kid on an adventure when the crew visits a new island. Also, his birthday is [[JapaneseHolidays May 5, Children's Day]].
** Justified because he ''is'' just [[spoiler: nineteen after the TimeSkip]]
** Boa Hancock is probably a more straight example. She may be 29 years old, and she may LOOK grown up, but she seems to have the mindset of a 12 year old girl. Which, if you know [[BreakTheCutie her]] [[MadeaSlave backstory]], [[FridgeHorror is appropriate.]] [[ShippingGoggles Her views of romance]] [[LoveMakesYouCrazy and love are probably the most telling.]] Luffy is oblivious to her having feelings for him, and she's oblivious that Luffy DOESN'T have feelings for her.
*** Although after [[spoiler: the TimeSkip]] Luffy does seem to be aware of Hancock's feelings, although he still doesn't seem to reciprocate them.
* Mashiro Kuna from ''{{Bleach}}'' is an ActionGirl who throws childish fits when things don't go her way and tends to talk in a babyish voice.
* Unnervingly, ''Manga/{{Gantz}}'' - an alien orb that forces dead people to battle in vicious, blood-soaked combat - has the sense of humor of a potty-mouthed grade-schooler. Witness his points assignments after the first game, where he nicknames Kishimoto "[[GagBoobs Titz]]", among other things.

* Sakura's mom in ''CodeBreaker'' is a [[HugeGuyTinyGirl tiny]] MoeBlob of a woman who only wears costumes.
* Misa Anehara in ''YokuWakaruGendaiMahou'' sometimes lacks maturity, seriousness, and common sense for being 25.
* Yogi from ''{{Karneval}}'' is 23, but he acts like a kid often. His default personality is sunshiny and cheery as well, which annoys Gareki to no end when that abundant, often oblivious cheerfulness is directed toward him.

* VisualNovel/{{Clannad}}: Fuko Ibuki is a rather extreme example. She's 25 when she shows up in ~After Story~, but she both looks and behaves like child. [[spoiler: Her behavoir, at least, is [[JustifiedTrope justified]], as she had just woken up from a coma that had spanned several years, and therefore still had the mentality of a child.]]
