History Manchild / VideoGames

** While on the subject, Mario himself easily fits into this category. 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.

* Big Boss, of all people, in ''VideoGame/MetalGearSolid3'' and ''VideoGame/MetalGearSolidPeaceWalker''. He has a {{Phobia}} of vampires, he gets ridiculously excited about eating things, he makes childish noises of disappointment when told not to eat things, is rather fixated on his mother figure, thinks making cardboard tanks and using bananas as firearms is a pretty neat idea, gets along as equals with a literal child, and still believes in Father Christmas.

* Max Hass from ''VideoGame/WolfensteinTheNewOrder'' is an almost literal version, due (presumably) to the fact that a good 1/4 of his skull is missing. His room is filled with toys (some of which you can go out of your way to recover for him at the base), and he's got an acute fear of loud noises.

'''Shepard''': You're my hero, Grunt.

-->'''Shepard''': Grunt, apologise to the nice man for setting his car on fire.\\

* Justified in the case of Grunt from ''Franchise/MassEffect''. Since he [[DesignerBabies didn't technically HAVE a childhood]] (unless you count accelerated growth in a vat while a MadScientist plays context-free videos for you to be a "childhood"), he comes out of the tank nearly fully grown but without a great deal of comprehension of the world beyond "if you squeeze this thing here, the gun goes bang and kills something". As a result, while he's fairly smart, he still plays with action figures, pulls out BuffySpeak on a regular basis, and mostly views Shepard, the player character, as a ParentalSubstitute who will teach him how to do all the important krogan things like break stuff and set it on fire. In the ''Citadel'' DLC, after he sets a Citadel Security car on fire, steals it and crashes it, this exchange can happen:

'''Grunt''': ...and I won't do it again.

* 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 suck 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.]]

'''Grunt''': (looking at his feet) I'm sorry I set your car on fire...

* 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]].

* ''CorpseParty'' has Yoshikazu Yanagihori, former CoolTeacher. As his mental illness progressed, he reverted to a childlike mental state, and eventually couldn't even convey his thoughts. People noted that he was still the same person he was before, so it was shocking when he apparently abducted four children and brutally killed three of them. [[spoiler:He didn't actually kill the children. He was manipulated into kidnapping them, but he was just an accomplice to the ''real'' killer... the surviving child, who was actually a malevolent spirit.]]
* Doctor Ivo "Eggman" Robotnik has shown some shades of this throughout the SonicTheHedgehog games. 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 AdventuresOfSonicTheHedgehog counterpart.

* 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.]]

* [[SuperMarioBros Luigi]] flirts with this [[AlternativeCharacterInterpretation depiction]] in the ''MarioAndLuigi'' series, except in ''[[MarioAndLuigiPartnersInTime Partners in Time]]'' where he dives into it headlong.

* Tingle from ''Franchise/TheLegendOfZelda'' series. A 35 year old man who believes he is the reincarnation of a fairy and spends his spare time floating around on a balloon searching for other fairies. Ramped up in ''VideoGame/TheLegendOfZeldaTheWindWaker'', where his HQ is a tower where his cohorts spin the top around to make magic happen... or something.
