History Manchild / VideoGames

* ''VideoGame/FireEmblemThreeHouses'' has Edelgard who is normally fairly composed in public, but in private her favorite gifts are toys like stuffed animals and games, enjoying lieing about and gouging on sweets, makes mocking voice impressions of others, and handles her attraction to people more like a smitten little girl than anything else. This is most likely a result of her DarkAndTroubledPast robbing her of her innocence early in life and affecting her emotional growth while leaving some desire to regain what she had lost.

* Yellow Heart, from ''VideoGame/HyperdimensionNeptuniaVictory''. Despite being physically powerful and having the visible age of the other [=CPUs=] ([[GagBoobs at least]]), she does everything to please her "parents", can only read and write very simple words, and is generally [[TheDitz sharp as a sack of particularly dull hammers]]. [[spoiler: Turns out she's an artificially altered Peashy, and therefore ''actually a child,'' despite "the big me" looking like an adult.]]

* Parsnip Bunner from ''VideoGame/{{Parsnip}}'''s behavior and understanding of things around him are particularly childish. However, despite his short stature and "soft" style of dress, Squirrel Girl refers to him as "old man", coupled with the fact that he's apparently [[OlderThanTheyLook old enough to own a house]]. He relentlessly pesters his neighbors without an understanding of boundaries, avoids the internet entirely out of a fear of cyberbullying, and handles knives in a, shall we say, [[KnifeNut playful manner]], among many other things. [=LeRose=] outright refuses to lend him candles because she doesn't trust him with anything involving fire, and why he needs the candles in the first place is also the result of his behavior.

* One interpretation of N's character in ''VideoGame/PokemonBlackAndWhite''. It's not played for laughs. [[spoiler:Indeed, it may actually be {{Foreshadowing}} of his... [[AbusiveParents father issues]].]]
** Heck, [[spoiler:N's upbringing]] in general does a lot to explain his ManChild tendencies, especially when you see [[spoiler:his toy room]].

* Snow Villiers in the ''VideoGame/FinalFantasyXIII'' trilogy.

* In ''VideoGame/FridayNightFunkinHD,'' Boyfriend is 19-years-old, yet he still has fun visiting a MallSanta.

* In ''VideoGame/FridayNightFunkinHD,'' Boyfriend is 19 years old, yet he still has fun visiting a MallSanta.

** Link in ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' is a version of this - albeit a sympathetic version that totally makes sense, since he was a child that was [[OvernightAgeUp in slumber for seven years and finds himself in a young adult body]]. Some of the text in the game reminds you that even though he looks grown and is battling some nightmarish monsters, Link is still a child.
* Mae from ''VideoGame/NightInTheWoods'' is a twenty-year-old college drop-out who acts like a rebellious teenager, compulsively committing petty crimes and having a hard time talking to other people her age about more adult concerns. This strains her relationships with her parents and most of her friends, except her partner in crimes, Gregg. Her flighty exterior also [[BeneathTheMask hides]] [[spoiler:some ''severe'' mental issues, including a textbook case of dissociation/derealization]].

* Kamiko from ''VideoGame/ShadowWarrior2''. Despite seemingly being in her 20s, she acts very immature and complains all the time. [[spoiler: turns out there's a good reason for this: she's half demon and literally only 3 years old!]]

* ''Franchise/SonicTheHedgehog'' games: Despite being 20 years old, Vector the Crocodile is no more mature than the rest of Sonic's gang, often arguing with 6-year-old Charmy Bee.

* Meredy in ''VideoGame/TalesOfEternia''. [[spoiler:Ten years before the start of the game, she witnessed her father Balir's murder at the hands of a group of people he and Meredy's mother Shizel thought they could trust (including Shizel's brother Hyades). In her grief and anger, Shizel was left open to possesion by [[EldritchAbomination Neried]] and annihilated everyone in the area save Meredy and Hyades due to them having the same potential to be possesed. In response to all of this, Meredy essentially froze her mind in the state of a six year old's.]]
* Luke fon Fabre from ''VideoGame/TalesOfTheAbyss'' starts out very gullible, emotional, demanding, self-centered, petulant, frustrating and stubborn. Most of the time, he acts like he's seven years old. [[spoiler: Which makes sense, because technically, he is. He was cloned from the ''real'' Luke fon Fabre seven years prior to the game's opening, and retained none of the original Luke's memories.]]

* In ''VideoGame/{{Littlewood}},'' Dalton, one of the Hero's former companions, is a strange, [[CloudCuckoolander spacey]] fighter who [[BigEater eats big,]] likes making loud noises, and who enjoys literally running around town. [[StockYuck He's also afraid of vegetables.]] However, he's a positive portrayal, as he's shown to be a very caring and fun-loving guy whose energetic nature means he makes friends easily.
* In ''Scary Robber Home Clash'', the burglars are not only stupid but very immature. Both of them will jump on the trampoline in the yard while shouting "Whee!" Lester even more so as he talks about wanting to watch cartoons and at one point dresses up as a ghost to scare Felix.

** The Gondawara Family from the infamous ''VideoGame/{{Yakuza 2}}'' side story "Be My Baby" are a bunch of yakuza who like to go to a special club, dress in diapers, and act like infants while women dressed as nurses coo over them. Kiryu gets dragged along but tries to back out respectfully, ultimately getting into a brawl with them when the Patriarch takes his reluctance as an insult. After the fight, Kiryt is ''thanked'' by the lower-level soldiers of the Gondawara Family, as their boss's fetishes were too weird even for them, but they didn't have a choice in the matter.

** Mario might be full of youthful exuberance, but Luigi often just comes across as childish and immature. It is particularly evident in the ''VideoGame/MarioAndLuigi'' series, where he's prone to crying like a child, though later games in the series tone it down some somewhat. ''Superstar Saga'' and ''Partners in Time'' has loud, exaggerated sobbing, ''Paper Jam'' has him quietly crying into his hands. Even his voice comes across as more childish than Mario's, despite Mario having the more higher pitched voice of the two.

* Snow Villiers in the ''VideoGame/FinalFantasyXIII'' trilogy, mainly the first two games. His go-getter demeanor combined with his hero complex tends to rub some people the wrong way. Lightning considers Snow an irresponsible idiot incapable of caring for Serah let alone taking care of himself. She can't stand Snow for his recklessness and disregard for proper manners and authority, calling him "chummy" and "arrogant", comparing him to a gang leader putting others in danger so he can play the hero. In ''Final Fantasy XIII-2'', Noel is equally irritated by Snow's brashness and tendency to charge into danger without thinking or considering the potential consequences.

** Subverted with regards to Pocket Circuit Fighter in ''0'' and ''Kiwami''. While he is obsessed with the rather childish hobby of slot car racing, he is an otherwise mature and well-adjusted individual, and even expresses concern that his hobby might be hampering other aspects of his life.

* ''{{VideoGame/Yakuza}}'': Subverted with regards to Pocket Fighter in ''0'' and ''Kiwami''. While he is obsessed with the rather childish hobby of slot car racing, he is an otherwise mature and well-adjusted individual, and even expresses concern that his hobby might be hampering other aspects of his life.

* ''VideoGame/{{Parsnip}}'''s behavior and understanding of things around him are particularly childish. However, despite his short stature and "soft" style of dress, Squirrel Girl refers to him as "old man", coupled with the fact that he's apparently [[OlderThanTheyLook old enough to own a house]]. He relentlessly pesters his neighbors without an understanding of boundaries, avoids the internet entirely out of a fear of cyberbullying, and handles knives in a, shall we say, [[KnifeNut playful manner]], among many other things. [=LeRose=] outright refuses to lend him candles because she doesn't trust him with anything involving fire, and why he needs the candles in the first place is also the result of his behavior.

* Adding the "Childish" trait to a Sim in ''VideoGame/TheSims3'' will result in one of these. In addition to their Fun meter depleting more quickly, they'll be more prone to watching the children's television channel, can play tag and play with children's toys (options normally unavailable to older Sims), among other things. Adding the "Evil" trait alongside this one can result in the [[PsychopathicManchild psychopathic]] version of this trope, too.
* ''Franchise/SuperMarioBros'':
** Mario easily fits into this category, though he's a distinctly positive portrayal of it. Aside from being a never-ending fountain of bubbly joy, he has absolutely zero qualms with playing with the Mini Marios his own company manufactures, indulges himself in any kind of fun activity regardless of how juvenile, and seems perpetually impossible to take the life-threatening obstacles he overcomes with anything but a whoop of excitement and charging headlong at it.

Even his voice comes across as more childish than Mario's, despite Mario having the more higher pitched voice of the two.

* Most of Capcoms most famous protagonists(with a few exceptions) are all manchildren/womanchildren with special abilities, quirks, and near emphasized cartoon quirks that highlight their games. Like [[VideoGame/DarkStalkers Morrigan]] as an overstimulated sex demon with a teenage party girl mentality, or [[VideoGame/SengokuBasara Date Masamune]] a brash and rambunctious feudal lord turned Japanese delinquent.

* One interpretation of N's character in VideoGame/PokemonBlackAndWhite. It's not played for laughs. [[spoiler:Indeed, it may actually be {{Foreshadowing}} of his... [[AbusiveParents father issues]].]]

** Bowser shows obvious signs of immaturity on a regular basis; he has nasty mood swings that scare even his most loyal servants, he never feels responsible for his failures, always looking for someone else to blame, and he is never satisfied with what he already has (he has castles in almost every land in the world), always wanting more. It gets even funnier when he meets his baby self in ''[[VideoGame/MarioAndLuigiPartnersInTime Partners in Time]]'': barely anything differentiates them in terms of personality, which clearly shows that Bowser has barely evolved mentally since his infanthood. No wonder why Kamek lacks patience...

* ''Franchise/SonicTheHedgehog'' games:
** Doctor Ivo "Eggman" Robotnik has shown some shades of this. In spite of his advanced knowledge of science and robotics, Eggman also appears to be very immature and is prone to throwing childish outbursts whenever something doesn't go his way. His television and comic depictions also exhibit some of these traits, most notably his ''WesternAnimation/AdventuresOfSonicTheHedgehog'' counterpart.
** Vector the Crocodile is also an example. Despite being 20 years old, he's no more mature than the rest of Sonic's gang, often arguing with 6-year-old Charmy Bee.
