History Main / PsychopathicManchild

* ''WebAnimation/HelluvaBoss'':
** Most of the cast save for Octavia since she is an actual teenager and does not demonstrate violently destructive immaturity unlike her parents and IMP. One poignant example being both Blitzo and Verosika causing mayhem to a beach over their petty gripes and act like high-schoolers that didn't grow up.

* ''WebAnimation/TheAnnoyingOrange'': Orange is a MadBomber who dishes out cruel, childish insults towards the foods he comes across and often ''[[LackOfEmpathy laughs]]'' when they get killed in front of him.

* Pretty Pink Ponytails from ''Literature/AngelOfDeath'' is a twenty-year-old woman who has a high-pitched voice, wears clothes made for small children (they're cut apart, and have extra fabric added to them.) She skips everywhere and loves to sing nursery rhymes. She also seems to enjoy torturing people and often describes things like death how a little girl would, despite seeming to comprehend these things fully. She also uses brightly colored handguns, and loves explosions.
** It's not clear if she really thinks she's a little girl, feels compelled to act like a little girl, or is just taking on the persona of a little girl. If the latter is the case, then she seems to keep up the act 24/7, as she's never been seen out of character, even in private conversations with her brother.
* WebVideo/TheAngryVideoGameNerd showcases this kind of personality in his early-mid episodes.

* The ''{{Film/Downfall}}'' [[WebVideo/HitlerRants parodies]]' portrayal of Adolf Hitler is this. For starters, try telling him that his Platform/{{Xbox Live|Arcade}} account has been banned for life.

--->"Look Vegeta...a Pokémon!"
** Freeza comes off as intelligent and cool-headed at first, but when it comes down to it he's really more like a bored rich kid who gets his entertainment from killing innocent people. As he loses more of his cool, his immaturity shows.

* One possible interpretation of HABIT from WebVideo/EverymanHYBRID.
* The Emperor of ''WebAnimation/IfTheEmperorHadATextToSpeechDevice'', when he's not GrumpyOldMan, has moments when he appears to be this.
-->'''''[[AC:Holy shit, a giant skeleton space robot planet that shoots molecule-breaking beams and destroys everything it spots... I want one!]]'''''
** Perturabo -- well, [[UnreliableNarrator according to his arch-enemy Rogal Dorn]] -- is a petulant manchild who holds onto grudges way too long.

* Nutty from ''WebAnimation/HappyTreeFriends'', [[VagueAge assuming he is actually an adult]]. He will do ''anything'' to get his candy, and while ordinarily [[TooDumbToLive he only hurts himself]], there are exceptions, most notably "Class Act" where he begins eating Sniffles alive because Sniffles [[ItMakesSenseInContext was wearing a candy cane costume.]]

* ''WebVideo/MrDeity'' is a [[JerkassGods Jerkass God]] who deliberately puts all sorts of evil things into his creation for no real reason and frequently inflicts [[DisproportionateRetribution horrifically cruel punishments for minor crimes]], but behaves in a very childish manner, particularly in the way he responds to criticism.
* WebVideo/TheNostalgiaCritic is a like a twelve-year-old boy with no supervision and a gun and you get the idea.
** WebVideo/TheNostalgiaChick. You get the impression sometimes that she genuinely doesn't know why Nella would be pissed off about ''cameras placed in her bedroom''. And there's no guilt involved either.
*** Elisa's characters Dr. Tease and The Makeover Fairy both enjoy torturing people through science and makeovers ''far'' too much.
** {{Genki Girl}}s Creator/AllisonPregler and WebVideo/PushingUpRoses occasionally wander into this trope when their excitement gets a touch too extreme.
* Every one from ''WebVideo/ProfoundMomentsInLeft4Dead2'' could count as this.

* The title character of ''WebAnimation/SaladFingers'', though this may be a subversion as he's more TrueNeutral in the "uncaring, detached, and having no regard for either good or evil" sense.
* [[Website/SCPFoundation Dr. Wondertainment]], considering the [[MyLittlePanzer toys]] he/it makes.

** Lately Liam "Brook" Brooks has shown signs of being one of these after having some SanitySlippage which resulted in AxCrazy tendencies.

* Cobalt from WebAnimation/WolfSongTheMovie and oh boy where do we start? He is hotheaded, lashes out at his own subordinates, ragequits whenever it becomes obvious to him that he is losing a fight and violently attacks anyone who dare point out the previous point to him. He also has a highly inflated ego and whenever it gets harmed, it is a certainty violence and sometimes even death may follow whoever harmed him, although he can and does also pull off brutal attacks unprovoked from time to time. The only reason he hasn't rebelled against the Death Alpha is because he is too scared to do so, but it's largely due to these antics of his that he has become a fan favourite among viewers

* The ''{{Film/Downfall}}'' [[WebVideo/HitlerRants parodies]]' portrayal of Adolf Hitler is this. For starters, try telling him that his UsefulNotes/{{Xbox Live|Arcade}} account has been banned for life.

* Actually possess a lot of power, intelligence, and/or prestige, but also have some childish qualities or behaviors, to fit in with a certain aspect of the story being told, or else [[UncannyValleyGirl advertise that there is something seriously wrong with them]], to make them [[NightmareFuel creepier]]. These are most likely to be a story's BigBad. These flaws are also often {{Fatal Flaw}}s, and will be a meaningful factor in why what should have been successful plans fail, or why they walk into something that [[SanityHasAdvantages more sane and/or mature villains would have avoided]].

* ''WebAnimation/{{RWBY}}'': Although he generally communicates in a verbose and melodramatic manner akin to an actor on a theatre stage, [[AxCrazy Tyrian Callows]] has a very infantile emotional dependence on [[TheDreaded Salem]]. He regards her as a 'goddess' and is desperate to please her. When he fails to complete his task, he initially cowers fawning madly to himself that Salem will forgive him. When he reaches Salem, he crawls towards her, begging for forgiveness. When Salem gently, but coldly, tells him that he has disappointed her, he dissolves into sobs of despair that attract a Beowolf. Tyrian then takes out his despair on the Grimm, slashing it over and over until his sobs turn into maniacal laughter; Cinder witnesses his entire breakdown, and [[HorrifyingTheHorror can only watch in open-mouthed horror]].

* ''Franchise/AceAttorney'':
** ''VisualNovel/PhoenixWrightAceAttorneyJusticeForAll'': Regina Berry is the teenage daughter of a circus ringmaster, who raised her without ever letting her know about the outside world. As such, she has absolutely no understanding of things like death or pain -- to her, everything is a game or a lighthearted practical joke. Unfortunately, this makes her completely (though unknowingly) selfish and cruel: she does whatever she wants to do whenever she wants to do it, never bothering to consider how her actions might affect the people around her. [[spoiler: The biggest example of this is the fact that she inadvertently put one of the circus's trapeze artists into a coma by playing a prank on him, and repeatedly talks about how he's "sleeping" instead of being nearly brain-dead.]] Albeit, it's somewhat downplayed as she's not ''intentionally'' malicious, and she ''[[InnocentlyInsensitive literally has no idea]]'' that she comes across as cruel. On the flip-side, though, [[spoiler:Acro]] definitely seems to think that she's a fully deliberate case of this.
** ''VisualNovel/GyakutenKenji2'': Blaise Debeste has a penchant for acting like a petty teenage bully, [[OcularGushers excessive weepiness]], playing with his lighter like an entranced child and other bouts of general immaturity, to contrast with his kid who tries (and fails) to act more mature than he really is. The psychopathic part comes from the fact he's unnecessarily creepy about it all, is terribly corrupt, [[ScrewTheRulesIMakeThem believes the truth is something he decides]], and [[spoiler:has killed several people, including his wife by implication, to cover for his crimes]].

If a hero is contrasted with this type of villain, its a case of ChildishVillainMatureHero.

* ''WebAnimation/{{RWBY}}'':
** Although he generally communicates in a verbose and melodramatic manner akin to an actor on a theatre stage, [[AxCrazy Tyrian Callows]] has a very infantile emotional dependence on [[TheDreaded Salem]]. He regards her as a 'goddess' and is desperate to please her. When he fails to complete his task, he initially cowers fawning madly to himself that Salem will forgive him.

Tyrian then takes out his despair on the Grimm, slashing it over and over until his sobs turn into maniacal laughter; Cinder witnesses his entire breakdown, and [[HorrifyingTheHorror can only watch in open-mouthed horror]].
** Cinder Fall can be [[TheChessmaster scheming]], [[FauxAffablyEvil charismatic]] and cunning. However, she feels so [[EntitledBastard entitled]] to take power from others that if she fails or doesn't get her way, she descends into sadistic, bullying tantrums much like a spoiled, haughty teenager. As she becomes more arrogant and less pragmatic, her flaws cost her victories and even ruin Salem's plans. Even after seeing that, she's still throwing tantrums and refusing to learn from her mistakes. [[spoiler:In Volume 8, Watts loses his patience and furiously dissects her flaws and failures, reducing her to tears.]]
** While a powerful and intelligent [[TheChessmaster Chessmaster]], Salem's motives are largely immature and childish. [[spoiler:Her StartOfDarkness began when the gods cursed her with immortality as punishment for her manipulating them into restoring her lover's life, and all of the death she's wreaked over the following years is essentially her [[NeverMyFault refusing]] to take responsibility for her own actions. Yang even [[DidYouJustFlipOffCthulhu calls her out on it]], outright likening Salem to a bratty child throwing a temper tantrum because something bad happened to her ''once'' and she didn't get a happily ever after.]]
