12* [[spoiler:Friend]] from ''Manga/TwentiethCenturyBoys'' is a rare MagnificentBastard version of this. As clever as [[spoiler:he]] is, it doesn't change the fact that [[spoiler:he is only trying to destroy the world because he never grew out of his childhood grudges.]]
13* ''Anime/{{Aggretsuko}}'': Anai in Season 2 quickly reveals himself as a LazyBum who ''really'' CantTakeCriticism. Just saying something, ''anything'' that even suggests he should do any actual work will send him into a rapid, babbling tirade before he bombards the recipient of his wrath [[StronglyWordedLetter with angry texts and emails]] [[PoliticalOvercorrectness where he twists their words into microaggressions and threatens to report them to upper management unless they apologize]]. He'll even go as far as to try and goad them into saying something he can record for ''blackmail material''. Before long, almost everyone in the office is terrified of him, even Director Ton, his ''boss'', and Retsuko '''''breaks down crying''''' at the thought of having to work alongside him. [[GossipyHens Kabae]], of all people, is the only person able to avoid pissing Anai off since, as a mother of three, [[HiddenDepths she realizes he's a kid fresh out of college who's just scared of having to grow up and work for a living]], and gently steers him in the right direction. Come Season 3, Anai has [[TookALevelInKindness taken]] ''[[TookALevelInKindness several]]'' [[TookALevelInKindness levels in kindness]]; he hosts a cooking blog, he's published a cookbook, [[LoveRedeems and he even has a girlfriend]]. Though he apparently still has his moments, such as angrily trying to convince a drunken Haida that his girlfriend is real.
14* ''Manga/AkameGaKill'': [[DragonInChief Esdeath]] is an example of the {{Yandere}} variant of this trope. While normally reserved, sophisticated and composed, [[TheHero Tatsumi]] manages to bring a school girl crush out of her and during the final battle in the manga, she blushes and drops her usual mature composure to act more childishly gleeful.
15* Cutthroat from ''Anime/AkudamaDrive''. Compared to the rest of the main cast, he's the most childish and unhinged. For example, if he ever comes across a red colored button, he'll use that chance to play around with it like a misbehaving child. However, he's also a serial killer who has killed 1,000 people, loves red so much that he will kill people just to see them covered in it, and is practically glued to Swindler because he thinks the amount of pink she wears is beautiful.
16* Ladd Russo of ''Literature/{{Baccano}}'' can get pretty child-like in his homicidal glee, and is usually shown [[https://www.youtube.com/watch?v=VNoITwTJiEM skipping]], babbling excitedly, dancing in pools of blood, or any combination of the three.
17** In the light novels Tick and Maria are described as having the personalities of 12-year-olds. Speaking of, Tick qualifies in the anime as well.
18** Ladd's LoonyFan Graham Specter may also count.
19* Bambi from ''Bambi and Her Pink Gun'' is incredible childish in many ways, but also subverts this in others. While she's a psychopath who acts almost entirely on instinct, she's also a vain health nut who doesn't eat anything she hasn't personally boiled and will kill you if you so much as ''smoke'' near her.
20* ''Manga/{{Berserk}}'': Before the Eclipse, many characters comment that Griffith has an almost childlike innocence about him (though since he would sometimes display this at inappropriate times, certain people would find it creepy rather than endearing). Indeed, one could interpret his dream of obtaining his own kingdom as a boyish fantasy he never did quite let go, and has hissy fits whenever things don't go his way (as him sacrificing his own comrades and then raping Casca during the Eclipse can perfectly show). Once he becomes [[DemonLordsAndArchdevils Femto]], he still tries to pursue this fantasy, but in a much more ruthless and remorseless way. And to drive the whole point home, there's the fact that, as the series' ArtEvolution progresses, he's drawn to look increasingly more cherubic and childlike despite being at least 2 or 3 years older than Guts is, showing how Griffith hasn't bothered whatsoever to move past his infancy.
21* ''Anime/TheBigO'''s Alex Rosewater. "This is my Big! This is my dome! You can't have it!" Also, to an extent, Alan Gabriel.
22* ''Manga/BlackClover'':
23** At his core, Licht is this, taking a childlike glee in revealing to his human subordinates that he never did care about them and taking out his anger over the elves' massacre on humans who were not even responsible for an event that happened five centuries ago. This is seen when Asta mentally speaks with him after he becomes a dark elf, during which he takes his form as a child before the massacre, showing that he never truly matured after this event.
24** Vanica Zogratis' childlike desire to fight makes her this. When fighting Noelle she treats it like a game of tag, telling her "here I come". She impatiently keeps on increasing the percentage of Megicula's power she's using when she's not even having trouble, [[spoiler:causing her to fall for Lolopechka's plan, who expected her to use all her devil's power and have Nero seal her then.]]
25* Chaka from ''Manga/BlackLagoon'' is introduced as a [[AffablyEvil dimwitted yet likeable]] {{mook}} who harbors [[HotBlooded an almost childlike enthusiasm]] for guns and shootouts... then said facade falls down, and we're faced with AxCrazy. [[spoiler: Who's also TooDumbToLive, as Ginji eagerly proves.]]
26* Wonderweiss Margela from ''Manga/{{Bleach}}'' fits pretty well. Under Aizen's full control, and because the BigBad removed all forms of intelligence, memory retention, speech and rationality, appears to have limited understanding of his actions, will attack Aizen's opponents, and heaven help you if you don't let him play with your hat [[spoiler:or aren't Yamamoto]].
27* Diva from ''Anime/BloodPlus'' exhibits some rather childlike behavior. For example, in episode 24, she bites young Riku and drinks his blood, then childishly laughs and jumps around in a white and blue PimpedOutDress when caught by the heroes, before she captures Saya herself and almost kills her. [[spoiler:Later, she ''rapes and kills'' Riku to impregnate herself.]]
28* Amaimon of ''Manga/BlueExorcist'' is a demon king who displays childish {{Cloudcuckoolander}} tendencies, uses his visits to the human realm mainly for sightseeing, and is extremely fond of candy. He's also excited by the thought of killing people and treats fighting like some sort of "fun" game.
29* Princess Buburina from ''Anime/{{Catnapped}}'' still acts like a spoiled child and throws temper tantrums when things don't go her way, she was a RoyalBrat growing up and was infected with a curse by a wizard that turns people into balloons because she was indirectly responsible for his daughter's death by making her walk an unstable tightrope for her amusement, and refused to accept that it was her fault.
30* ''Manga/ChainsawMan'':
31** Power combines a Devil's bloodthirst and love of tormenting humans with the personality of a particularly obnoxious 7-year-old, refusing to eat vegetables and rarely taking care of her personal hygiene. [[LampshadeHanging Makima even calls her]] Denji and Aki's "[[AnnoyingYoungerSibling bratty little sister.]]"
32** The Future Devil is energetic, cheerful, loves to dance, and seeks to entertain itself... [[FauxAffablyEvil with the horrible fates of its contractors]]. It signs on with Aki purely because ItAmusedMe [[spoiler:[[BewareTheSillyOnes and because his death allowed it to escape]]]], and tries to make him shout "The future rules!" before summoning it.
33** Yoru [[spoiler:is the AnthropomorphicPersonification [[HorsemenOfTheApocalypse of war and senseless violence]]]], which belies the fact that she has the temper and temperament of a child. When Asa and Yoru are inadvertently saved by Chainsaw Man, Yoru has a tantrum screaming about how much she hates him before falling asleep. When Asa calls Yoru stupid for [[DramaticIrony thinking that Denji is Chainsaw Man]], Yoru throws a tantrum until Asa takes the insult back.
34* Kaminashi from ''Manga/ChoujinSensen'' turned out to be quite the delusional lunatic who believes that he brings salvation to good-natured women by [[spoiler: killing them, thus "saving" them in a world he perceives as corrupted and rotten. The fact that he still believes he's innocent is even more disturbing considering how he murdered 5 female victims (including a 3-year-old girl) within half a year.]]
35* ''Manga/ChronoCrusade'' has Joshua Christopher, who was kidnapped by the BigBad as a young boy and given [[WithGreatPowerComesGreatInsanity powers that turn him insane]]. Although he's 15 in the main bulk of the story, he still sometimes acts like the child he was when he was kidnapped, treating attacking a girl as a "game" and pouting about pudding being ruined right before slaughtering the demons responsible. The anime version emphasizes the "childlike" side, including [[spoiler:the ending having him lose all of his memories and reverting back to the personality he had as a kid]], while the manga makes him more mature and aware but possibly more insane.
36** The anime also seems to treat Shader this way, by keeping her GenkiGirl personality but changing her morality from a grey shade to nearly completely black, giving her a sadistic streak to boot.
37* ''Manga/{{Claymore}}'':
38** Miata is little more than a child (who actually breastfeeds from Clarice to stay calm) though several other fighters don't realize this, what with her ungodly ability to kill masses of Yoma at a time. And, if necessary, with her ''bare hands''.
39** Priscilla may count too, at least until she [[OneWingedAngel awakens]].
40* Mao from ''Anime/CodeGeass'', whose child-like attitude is slightly justified by the fact that he was orphaned at a young age and never received anything even resembling a traditional upbringing. That does ''not'' justify the wanton MoreThanMindControl he engages in...
41** It's even more obvious in the supplemental reading, in which he is, in a word, ''[[ChildrenAreInnocent so innocent]]'' that he [[MoreThanMindControl manipulates]] and kills people with evil impulses to [[LoveMakesYouCrazy stop them from hurting his beloved C.C.]].
42** Also, due to the young age at which C.C. gave him the Geass and the fact that it evolved at such a young age too, he's never really matured, or had a chance to.
43* Tongpu from the ''Anime/CowboyBebop'' episode "[[Recap/CowboyBebopSession20PierrotLeFou Pierrot Le Fou]]" is an unstoppable killing machine who is terrified of cats and reveals his childlike nature upon being wounded by Spike. Exposition explains earlier on that this mad, efficient killer was [[TykeBomb the result of experiments to turn him into what he is today]], but the experiments had the unintended side effect of regressing his mind, and Jet remarks (paraphrasing Freud) that [[KidsAreCruel "there is nothing so pure and cruel as a child"]]. His fear of cats is the result of classical conditioning, with the researchers' cat having been constantly visible to him through a window during the experimentation (leading him to associate cat imagery with the suffering he endured), and his reaction to Spike's attack is the first time we truly grasp just how far back he's gone. [[spoiler:The "child" part of his manchild nature is what ultimately becomes his downfall.]]
44* Tamaki, the Promoter of ''Manga/DeadmanWonderland''. When he isn't causing the deaths of or torturing inmates he's often found playing with toys in his office, including a Lego model of the prison and a dancing flower. [[spoiler: He's also a bit of an RPG {{Otaku}} and sees the Wretched Egg as a BigBad to defeat.]]
45** And the reason that the prison exists in the first place? He was a bum man-child living off his mother when The Wretched Egg caused an earthquake that destroyed his computer along with his game data!
46** There's also Mockingbird. He was by all accounts downright ''terrifying'' in battle and is one of the most powerful and feared Deadmen in the series this side of Wretched Egg, but outside of the ring, he was childish, playful, and didn't seem to take anything seriously except for his MoralityPet. [[spoiler:Hagire [[BodySurf Body Surfed]] into him.]]
47* ''Manga/DeathNote'':
48** Misa Amane is an [[TheDitz endearingly naive]] {{Kawaiiko}} who has a very childish demeanor that persists well into her 20s, [[TheFashionista obsesses over fashion]] like any young girl, is completely boy-crazy, and was able to translate her {{Moe}} appeal [[GeniusDitz into a successful career]] [[IdolSinger as an actress/model]]. All this is likely because her parents were murdered while she was still a child, trapping her in a perpetually immature state. Unfortunately for the world, this apparently happened before the Amanes had the chance to explain to their daughter that [[AmbiguousInnocence human life has an intrinsic value beyond being useful]] to Misamisa-chan, who latched on the man who used his Manga/DeathNote to kill the burglar years after the actions that shattered Misamisa's mind. [[AxeCrazy The results weren't pretty]].
49*** It's possible that she ''was'' just [[NaiveEverygirl a nice, cute, but immature young woman]] ''at least'' partially driven insane by the Death Note. Given Light Yagami's [[JumpingOffTheSlipperySlope flying leap off the slippery slope]] from an idealistic young man who [[WellIntentionedExtremist thought he was doing the right thing]] to a maniacal tyrant willing to kill anyone and anything [[AGodAmI to further his raging god complex]] and Teru Mikami's astonishingly short break from a focused, serious lawyer [[KnightTemplar with an inhumanly high standard of justice]] to a barely coherent AxCrazy psychopath, it's not too hard to imagine that the Death Note has an unspoken WithGreatPowerComesGreatInsanity rule that Misa was affected by. For example [[spoiler: after she permanently gives up the Death Note]], she's [[GenkiGirl completely harmless and probably quite fun to be around]], unless you're Takada.
50** Light himself qualifies. When L details the psychology of Kira to the police, one of them suggests that they could stop him by no longer publishing the name of convicts in the news, as he clearly was getting the names of his victims from the media. L states that won't work because Kira will then simply start killing people he ''thinks'' are guilty and will further blame the police for any innocent people he kills, specifically identifying his childlike personality as the reason for this. Sure enough, Light does display lots of childlike evil throughout the series, such as killing the fake L [[DisproportionateRetribution for insulting him on national television]] and his need to [[EvilGloating gloat]] to L and Near when he thinks he's beaten them. His VillainousBreakdown at the end takes the form of a blatant temper tantrum.
51** Ryuk is a cruel monster who sets everything off because he's bored.
52** Mello also fits this trope. Although very smart and willing to actually do something, he cares far more about besting Near than he does about bringing Kira to justice, and is prone to violence. He also eats a lot of chocolate.
53** Teru Mikami is an even more blatant example than Light. While Light's incredibly naive outlook on morality is based on the philosophical pondering of a high school student, Mikami's is based on the philosophical pondering of a ''middle school student''. And Light at least has the excuse of ''being'' a high school student. In fact, his motivation for helping Light is purely due to a particularly bad case of middle school bullying that he blew way out of proportion.
54* ''Literature/TheDevilIsAPartTimer'': In his first appearance, Lucifer [[LovesTheSoundOfScreaming reveled in the screams he caused]] and treated the fight with Maou and Emi as a big game as he destroyed everything around him.
55* Puppetmon from ''Franchise/{{Digimon}}'', anyone? He kidnaps Takeru in order to play hide and seek. While trying to kill his brother Yamato and the rest of his friends, and then Takeru himself. Way to go.
56** Arguably Diaboromon from ''Anime/DigimonTheMovie''. There isn't much known about it, but consider that the e-mails it sends suggests that it sees the battle as a game, and that the only sound it makes (in the original version) is a [[HellIsThatNoise creepy]] [[GigglingVillain childish giggle]].
57** Yukio Oikawa from ''[[Anime/DigimonAdventure02 02]]'' is a more sympathetic example, never really maturing after he discovered the Digital World [[spoiler: and especially after his best friend died]]. He finally starts growing up after he meets [[spoiler:the father and son of his late best friend]] again and realizes that they must miss him even more than he does. [[spoiler:Sadly, it doesn't matter since he's been possessed by Myotismon.]]
58** ''Anime/DigimonFusion'': Despite being a GadgeteerGenius, ManipulativeBastard, and [[TheChessmaster Chessmaster]], [[spoiler: [=AxeKnightmon=] falls under this. Ironically enough, when he first swayed Ewan Amano to his side, he tricked Ewan into thinking that the Digital World was simply a game. Despite knowing it to be otherwise, [=AxeKnightmon=] treated the war for the Digital World like a game. He treated all those who surrounded him like toys, demonstrating a sadistic streak along the way. And the final goal of all his efforts? Simply to ''surpass his big brother,'' Lord Bagra, in power. He’s essentially a SpoiledBrat willing to do anything and everything to one-up his big brother, and outright admits that he’s DrivenByEnvy. Tellingly, Bagra himself calls him out on this, claiming that his short-sighted attitude was his greatest weakness.]]
59** ''Anime/DigimonGhostGame'':
60*** Petermon is a CorruptedCharacterCopy of ''Literature/PeterPan'' who abducts human children & Rookie-level Digimon to his LandOfFaerie PocketDimension called "Never-Ever Land" while attacking the teenage protagonists who try to stop him, calling them "adults" [[BoomerangBigot despite being an Adult/Champion-level Digimon himself]]. When an Elecmon casually says he wishes he were bigger after missing the ball in a soccer game, Petermon takes it to mean that he wants to Digivolve and threatens him with violence until he begs for mercy.
61*** Digitamamon was an EvilFormerFriend to Angoramon that started [[ToServeMan eating people]] while being [[BlueAndOrangeMorality unable to fathom that it was wrong]], and despite being an Ultimate/Perfect-level Digimon had a childlike voice and cry.
62*** [=ExTyrannomon=] and [=WaruMonzaemon=] are Ultimate-level evil plush toy Digimon much bigger than a normal person, but they are an absolutely nasty duo who manipulate and flatter a young girl to let them wreak havoc and turn them into dolls as they always wanted to.
63*** Cthyllamon is a ''Mega-level'' resembling an EvilKnockoff of [=MarineAngemon=] who sees humans as lower lifeforms and wants to submerge the world in Digital Water just to create a playground for his subordinates, uncaring that the Digital Water turns people into catatonic water fountains. By the time the trio gets involved with him, his subordinates had flooded an entire town and a cruiser worth hundreds of victims.
64*** The FinalBoss is an Ultimate-level that can single-handedly decimate Mega-level Digimon, but has an extremely simplistic view of "eat or be eaten" towards the Digimon world and cackles like a maniac upon mortally wounding Gammamon and driving Hiro into despair just because [[spoiler:he tricked him into separating from Gammamon]].
65* ''Manga/{{Domu}}: A Child's Dream'', one of Creator/KatsuhiroOtomo's lesser-known works, features Old Cho, a powerfully psychic but senile old man whose [[ForTheEvulz primary source of amusement]] happens to be wreaking mischief on his fellow tenants in a large apartment complex. Unfortunately, he also has a mean streak a mile wide, so his pranks are often lethal -- and if he's denied his fun, he's prone to throwing tantrums. No one should be present when this happens. Fittingly, [[spoiler: the one who faces and defeats Old Cho is Etsuko, a [[WiseBeyondTheirYears Wise Beyond Her Years]] LittleMissBadass with similar psychic powers and a PluckyGirl nature.]]
66* ''Franchise/DragonBall'': With a few exceptions, ''all'' villains in the series are this to varying degrees:
67** Emperor Pilaf acts like a SpoiledBrat and throws temper tantrums when he doesn't get his way.
68** General Blue technically qualifies. Despite his dignified demeanor, the way he takes pleasure in inflicting pain on others can be compared to a schoolyard bully beating up on smaller children. Although he has [[SorryImGay other reasons]] for disliking Bulma, his exact reaction regarding Bulma's attempts at seducing him is extremely similar to a little kid not wanting to interact with the opposite gender due to a fear of cooties.
69** Vegeta before his CharacterDevelopment is completed. His determination to surpass Goku and constant bragging about how he's the Prince of all Saiyans sounds like a petulant spoiled brat throwing a tantrum because no one's kissing his ass. Especially in the Buu Saga: while fighting Goku as Majin Vegeta, he goes off on a big rant over how Goku's existence is insulting to him because even Goku's ''son'' was stronger than him at some point.
70** Goku’s BigBrotherBully Raditz who is a total {{Jerkass}} easily throws a fit and would not hesitate to kill his own baby brother and nephew.
71** His fellow Saiyan, Nappa, doesn't fall too far behind. He fights by basically playing with his prey and has a tantrum when Goku beats him up.
72** ''Everyone'' in the Ginyu Force is this to one or another extent; Recoome is just the most blatant example. These are the ruthless elite soldiers of Freeza who also love to make very hammy {{Sentai}} poses to introduce themselves to friend and foe alike and decide things via rock/paper/scissors.
73** Even Freeza gets to have traits of this. He often behaves like a SpoiledBrat despite being at least 70-years-old. This is shown in ''Resurrection 'F''', where he whines and throws a temper tantrum that involves punching small craters into the ground when [[spoiler: Vegeta beats him out of his GoldenSuperMode]]. Another notable example is when he comments in hell about Goku fighting with Kid Buu.
74-->'''Frieza''': Stupid little Saiyan monkey! *blows raspberry*
75** Android #17 treats the hunt for Goku like a game and deliberately going the roundabout way of finding him for fun. Even more so (in fact a cross between B and E) in the BadFuture of Future Trunks' timeline, where his sister is one of these also to the point 'go on murderous rampage' is her default response to not getting what she wants; in fact, they spent ''twenty years'' going on random killing sprees and keeping score of the kills. When Future Trunks shows up and she wants to kill him to blow off steam, #17 agrees to let her do so, but remarks they'll be throwing away weeks of playtime if she does, treating it more like a game than their nemesis. Trunks actually [[TheReasonYouSuckSpeech calls him out on it]] before killing him.
76** In his second form, Cell literally whines and throws a temper-tantrum because Vegeta won't let him absorb Android 18 and reach his Perfect Form. When he is forcibly reverted to this form after Gohan makes him spit out 18 he attempts to [[SuicidalCosmicTemperTantrum destroy the Earth]], a reaction that can be compared to a petulant child [[FlippingTheTable kicking over the table]] after losing a board game. In the former case, Vegeta calls him on it:
77--->'''Vegeta''': ''You're'' the one who started this game, and now that you're losing, it's no fun anymore? You're just a big baby!
78*** Even in his perfect form, he had a giant VillainousBreakdown when Gohan completely surpass him after reaching Super Saiyan 2. He tries to destroy the Earth with a giant Kamehameha. When that fails, he actually screams like a child.
79** Babidi, despite [[ImmortalImmaturity being hundreds of years old]], acts like a SpoiledBrat. He is prone to throwing tantrums, whining, and bullying others when things don't go his way. He also treats hurting and killing people like some kind of game, laughing in delight when Buu ate cities or when his former loyal servant Dabura was beaten senseless and devoured.
80** Fat Majin Buu from ''Anime/DragonBallZ'' has no idea that what he's doing is wrong, and is single-handedly converted to good by Mr Satan / Hercule. Super Buu sounds increasingly intelligent once he starts absorbing people, but still throws tantrums when he's outmatched. Finally there's Kid Buu, who doesn't have any desires that don't involve blowing things up.
81** Broly's motivation to kill Goku is that Goku's nonstop crying scared him and kept him awake for days on end when they were babies in the same "nursery". The English version plays this up with his Kiai, which sounds less like a Kiai and more like he's throwing a tantrum.
82*** ''WebVideo/DragonBallZAbridged'' put it really well:
83---->'''Vegeta:''' But you don't understand! [[DisappointedByTheMotive The Legendary Super Saiyan is motivated by a crying infant]]! He is a literal giant fucking baby!
84** Chilled from ''[[Anime/DragonBallEpisodeOfBardock Episode of Bardock]]'' presumably qualifies under this trope, as he has shown himself to be exceedingly childish, and yet was shown to be even more ruthless than even ''Frieza'', notably killing one of his soldiers while in a good mood just because the soldier was unfortunate enough to just happen to be blocking his view.
85** Beerus, the BigBad of ''Anime/DragonBallZBattleOfGods''. While incredibly powerful, to the extent that he can curb-stomp Super Saiyan 3 Goku with [[FingerPokeOfDoom one finger]], his attendant Whis has to remind him to brush his teeth and eat his vegetables. He's also prone to losing his temper and responding violently to petty things: for example, he blew up North Kaiō's original planet simply because Kaiō beat him at a video game, and also threatened to blow up the Earth purely because he was pissed that Majin Buu ate all the pudding at Bulma's birthday party after Beerus explicitly asked him to share. ''Anime/DragonBallSuper'' continues with this as, when he's told that traveling to Earth would take about 26 minutes, he complains that he could watch an anime in that time. (This same comment is made in ''Battle of Gods'', but in a much less irritated and more matter-of-fact tone.)
86** Beerus' twin brother, Champa, hovers between this and ManChild. On one hand, he's more mellow than Beerus since he doesn't have a bunch of {{Berserk Button}}s and not as prone to {{Disproportionate Retribution}}s. He's even willing to share food, while Beerus nearly blows up the Earth over pudding. Then he tries to [[spoiler: murder his entire team from Universe 6 for the 'crime' of [[SoreLoser losing against Universe 7 during the tournament]]]].
87** Zamasu, the BigBad of ''Super's'' Future Trunks Saga, has shades of this. His smugness and AxCrazy glee at attempting to kill Goku come across both as a petulant child holding a grudge as well as trying to rub his accomplishments in his face. He also holds the entire Saiyan race in contempt as thuggish animals simply because Goku is one of them. It's also heavily hinted that many of the actions he committed during his genocidal rampage was purely to spite Goku. And the main source behind his StartOfDarkness? He's just pissed that Goku, a mortal, was able to defeat him, a god, in a simple sparring match.
88** Barry Khan is such a self-centered creep that when Videl, a ''married'' woman, rejects his advances, he can't handle it and goes so far as to try to ruin her marriage to Gohan out of spite. Videl sees through his actions right away and snubs him yet again, all the while [[TheReasonYouSuckSpeech remarking how pitiful it is that Barry is treated like royalty, yet is so insecure that he's willing to stoop to trickery and blackmail when he doesn't get his way]]. Immediately afterwards, Barry throws a screaming tantrum and pounds on his car with his bare hands, sulking like a child who didn't get what he wanted.
89** Zeno, the [[GuardianOfTheMultiverse ruler of the multiverse]]. He's genuinely innocent and noble, but according to Beerus, [[PureIsNotGood this innocence is]] ''[[PureIsNotGood exactly]]'' [[PureIsNotGood why Zen-Oh is so dangerous]], as [[LackOfEmpathy he simply doesn't know the value of life]], and due to the authority he holds and the power he wields, [[BewareTheSuperman there is no one willing to admonish or scold him when he does do something wrong]]. This is why he can so casually and cheerfully threaten his subordinates with atomization, play "games" that involve destroying planets as a consequence without so much as batting an eye and even host a tournament that will led to the erasure of an ''entire'' multiverse as penalty for their failure.
90** Baby of ''Anime/DragonBallGT'' [[MeaningfulName definitely lives up to his name]]; despite having the tactical cunning to outsmart and outfight almost every living ''Dragon Ball'' character, he's immensely immature. It rapidly becomes clear his revenge against the Saiyans is just something he's using as an excuse for his own desires. He's incredibly childish: focused mainly on taking things for himself, having the habit of "playing" during fights to the point of playing pretend (he melodramatically pretended to struggle against Uub until he was "done playing", and upon getting his Golden Great Ape form, he proceeded to pretend he had gone berserk just to play with his new powers), and having a childishly short fuse. In fact, during Goku's first fight with Baby Vegeta, he learned what Baby's biggest weakness was; he's incredibly susceptible to taunting, and will lose his cool even if his opponent is obviously bluffing. To top it all off, when he was finally defeated, he completely abandoned everything he had gained, and his mission for revenge, just to run away and save himself.
91* Jashin of ''Manga/DropkickOnMyDevil'' is a [[ReallySevenHundredYearsOld thousand-year-old lamia]], and yet acts immature and childish, often manipulating Medusa into providing her with money solely to entertain herself. Aside from that, she spends a duration of the series trying to kill Yurine, and event fantasizes about bloodily killing her while laughing like a toddler.
92* Izaya of ''Literature/{{Durarara}}''. One of the rare ManipulativeBastard versions. It becomes quite obvious as the series progresses that he sees everyone and everything around him as little more than toys to be played with until they break.
93** This is all lampshaded by the fact that Izaya plays a strange mixture of games he uses to represent the events around him. Meaning, he literally sees the world as a game. This is made even creepier by the fact that he repeatedly destroys the pieces by lighting them on fire.
94** In his spin-off, the characters are interviewed about Izaya, and a general consensus is that while he cannot be called good or evil, he acts on his own whims and is like a child given too much power.
95%%* Lucy from ''Manga/ElfenLied'' is a mixture of types C, D [[spoiler:(counting Nyu)]], and E.
96%%** The silpelits can also qualify even though they're chronologically children because they age [[YoungerThanTheyLook quicker]].
97[[/folder]]
98
99[[folder:F-O]]
100* ''Anime/FistOfTheNorthStar'' the Fang Clan are a BanditClan of AmbiguouslyHuman thugs led by their massive father. Who when not killing villagers for supplies, enjoy playing with [[https://www.youtube.com/watch?v=t8nrmm3H-8A Panda plushies]] and gushing over people or things they find cute.
101* Renge in the ''Manga/FlameOfRecca'' manga, who is so childishly nuts she tore up a Teddy Bear just because it doesn't answer her when it doesn't have a speaking device, only to cheerfully laugh to ask for her Papa to get her a new one. Speaking of her Papa, Mori Kouran, she thinks her Papa's horrendous monstrous look after [[spoiler:fusing with Tendou Jigoku]] looks EXTREMELY COOL. She doesn't end really well.
102* ''Anime/{{FLCL}}'': Mamimi Samejima acts closer to an elementary school student despite being a high schooler, and is very clearly mentally unstable. This is one of the few things in the show that is ''not'' PlayedForLaughs.
103* ''Manga/FruitsBasket'':
104** [[DomesticAbuse Akito]]. He's essentially the same at age 19 as he was when he was little -- a spoiled brat with a god complex and a crippling fear of abandonment. [[spoiler:This is because '''[[GenderReveal she]]''' was horribly abused from ''before'' birth by her mother, who forcibly raised her as a boy due to petty jealousy and drilled in her mind the idea that nobody loved her, nobody respected her, and everyone would abandon her, which caused Akito to snap when she was in her early teens and become the BigBad.]]
105** Ren Sohma [[spoiler:aka the aforementioned abusive mother of Akito.]] Not only is her ultimate reason for [[spoiler:abusing her daughter]] [[EvilIsPetty ultimately very bratty]] ([[spoiler:being jealous because Akira, her late husband and Akito's father, loved the idea of being a dad]]), but at some point, she [[spoiler:tries to kill Akito... over a box that belonged to the dead Akira, simply because she believes everything Akira owned was hers.]]
106** Kyo's AbusiveDad is nothing but an annoying, whiny brat in a grown man's body, using his own son as TheScapegoat for ''everything'' that goes wrong with his life, no matter how small. Best cemented in his and Kyo's final meeting; Kyo's father throws a temper tantrum over the fact that the son he's always hated and dehumanized is moving on with his life and has found love and is left whining and shouting at Kyo that he "won't allow it" even as Kyo turns his back on him and walks away.
107** Sawa Mitoma's mother in the sequel ''Another'' had shades of this. She's a grown woman who gets her kicks by constantly bullying and insulting her teenage daughter and any friends she makes and has been doing so since Sawa was in elementary school.
108* ''Franchise/FullmetalAlchemist'':
109** [[Manga/FullmetalAlchemist Original manga]] and ''Brotherhood'':
110*** Gluttony is a ridiculously strong ArtificialHuman over 90-years-old with the temperament and intelligence of a young boy and stuck in the infant phase of [[ExtremeOmnivore wanting to shove everything in his mouth.]] Throughout most of the series, he's reliant on his "keeper" Lust to do the thinking for him (his main input being to ask her if he can eat people). He sees her like his mother and [[spoiler:when she dies, the poor guy suffers a nervous breakdown; and though in the manga he is still able to function properly, he did not forget her death, going after Mustang for revenge and tearfully calling for her upon death.]]
111*** Envy, a {{shapeshifting|Trickster}} ArtificialHuman who's 175 years old is a sadistic, misanthropic psychopath who often acts even less mature than the teenage hero Edward. They're arrogant, impulsive, petty, sarcastic, gloat about the atrocities they've committed like a [[TeensAreMonsters juvenile delinquent or bully]], become a whiny DirtyCoward and throw tantrums when they're outmatched, and of course they're [[InferioritySuperiorityComplex extremely insecure]]. They also pick a young, cute [[ShapeshifterDefaultForm preferred form]], and their [[TechnicallyNakedShapeshifter "outfit"]] choice looks like they bought it from Hot Topic.
112*** Shou Tucker is a grown man in his early fifties but displays a complete lack of awareness of other people's feelings, to the point that the idea that anyone would be angered at his [[spoiler:turning his own family into experimental abominations, thereby ruining their lives]] [[EvilCannotComprehendGood did not occur to him]] until it was too late. After being exposed, instead of introspecting his actions, he taunts Edward over the latter's failed attempt at human transmutation and how [[NotSoDifferentRemark it makes them identical]], [[NotSoSimilar which falls flat]] given that Edward actually learned from his mistake and wants to atone for it. It basically comes off as Tucker acting like a child going "Nyah nyah-nyah nyah nyah!" When placed under house-arrest to be decommissioned and subpoenaed, all he does is [[NeverMyFault whine about how no-one understands him]], [[EntitledBastard having expected to be rewarded instead of punished]].
113*** [[BigBad Father himself]]. Not immediately obvious as Gluttony due to Father for the majority of his screen time as a stoic and foreboding older looking man but deep down he's this. When Hohenheim describes to Ed that his attempts to burn their home were akin to a child's hiding the mess they made, it is strongly implied that he's referring to Father's hiding the existence of Xerxes when he makes the comparison. When forced to remove his pseudo-Hohenheim skin, Father acts in a sadistic and childish manner until he absorbs God, resuming his trademark stoicism, implying he only acts stoic as a means to act in a manner of what he sees an adult as. His rebellious attitude towards Hohenheim and Truth plays into a child trying prove he's superior to his father, both in literal and a a [[SatanicArchetype biblical devil aspect]]. When he finally gets taken back to the Gate, Father whines like a brat begging not to be punished. It is very telling of his Gate of Truth being blank that truly speaks of his lack of maturity.
114** [[Anime/FullmetalAlchemist2003 2003 anime]]:
115*** Downplayed with Envy as [[GenderFlip he's]] a lot more competent and confident than his manga counterpart, but he's even more of a murderous psychopathic bastard. He's also got the motivation of [[spoiler:being abandoned by his father Hohenheim]] and has the lifelong goal of murdering him, which can certainly come off as juvenile; especially when he throws a tantrum when [[spoiler:Dante]] incorrectly tells him [[spoiler:Hohenheim has died]], meaning he didn't get to kill him.
116*** In contrast to his sophisticated, FauxAffablyEvil philosopher manga/''Brotherhood'' counterpart, Kimblee in the 2003 anime is a rude low-functioning SociopathicSoldier who treats the red stones fueling his explosions in genocidal warfare like toys.
117* Gates from ''Literature/FullMetalPanic'' is a mysterious man [[EstablishingCharacterMoment whose first act was to get rid of the subordinate who argued with him by kicking him out of a helicopter]]. An extremely volatile man with a ridiculous TriggerHappy attitude, Gates seems to enjoy big explosions and being cruel to people like a child that likes crushing their toys, but with the difference of being 40 years old and not even bothering to hide it one bit.
118* ''Franchise/{{Gundam}}'':
119** DarkActionGirl Nena Trinity from ''Anime/MobileSuitGundam00'' is pretty, spoiled, cheerful, friendly, mock-fights with her brothers, will happily invade your personal space and kiss you if she thinks you're cute, has a really funny mascot in the form of her purple Haro... but after being raised as a Tykebomb ArtificialHuman with ''no'' concept of morality, she will bomb your house if she's got to work while you have fun at weddings. And then she'll be all "Whoopsie! :3" when asked why she did that.
120*** In the side materials, it's strongly implied that there's a pretty good reason for this: [[spoiler:17-year-old Nena was kept in stasis almost from birth... and only woke up around ''seven'' years before the series starts. As such, her mental psyche isn't the same age as her physical body and she's a little girl in the body of a teenager]]; such circumstances would take a toll on the mental/emotional maturity of '''anyone'''.
121** [[EvilOverlord Wong Yunfat]] from ''Anime/MobileFighterGGundam'' is one of the rare MagnificentBastard versions. He ''loves'' [[SweetTooth eating chocolate]] and is seen in his pajamas as well as leaning on a giant teddybear at one point, and some of [[ThisCannotBe his reactions]] to seeing [[VillainousBreakdown his plans going wrong]] [[SpoiledBrat can be seen as very childish]]... but Wong's own [[TheChessmaster cunning plans and back-up plans]] make him far smarter and more ruthless than the average PSM.
122** Rosamia Badam from ''Anime/MobileSuitZetaGundam'' is a 17-going-on-18-year-old DarkActionGirl who, outside her mecha, has the mentality and the fears of a little girl, latches innocently on whoever she sees as a ReplacementGoldfish for her dead older brother, and is unable to take care of herself in a normal environment. In her case, it's ''very'' justified: Rosamia not only is a survivor of the infamous Zeon ColonyDrop of the One Year War, which happened when she ''was'' a little girl but was subjected to cruel experiments that messed up her mind even more.
123** ''Anime/MobileSuitGundamSEED'' has Muruta Azrael, a [[TheSociopath psychopathic]] [[FinalSolution genocidal maniac]], motivated by childhood grudges, and possessing the maturity level of a particularly vicious teenager.
124** ''Anime/MobileSuitGundamSEEDDestiny'' has Rosamia's even more handicapped expy, [[TheOphelia Stella Loussier]], who while [[DarkActionGirl very efficient in combat]], is a 5-year-old outside of her mecha, sometimes screaming about how the "scary things" are coming for her and flipping out in sobbing meltdowns at the mere mention of death. Her teammate and sort-of brother Auel Neider is only marginally saner, and while he can sort-of handle Stellar (as in, [[KnightTemplarBigBrother attacks anyone who tries to approach her]]) can be driven into a breakdown by the mention of his mother.
125** ''Anime/MobileSuitGundamAGE'' has [[spoiler: the grown-up Desil Galette]]. To put it in perspective: [[spoiler: he was introduced in the first part as an EnfanteTerrible, and in the second part he may be in his 30's but he hasn't actually changed his attitude ''and doesn't even really plan to''.]]
126** [[spoiler:[=McGillis=] Fareed]] of ''Anime/MobileSuitGundamIronBloodedOrphans'' is a tragic literal example. His horrifying childhood left him with a profound LackOfEmpathy and emotionally stunted him at about 8-years-old, leaving him with a child's simplistic view of the world and ensuring that he could only really emotionally connect with people of his own mental age (like his child-bride in an ArrangedMarriage). He manages to rise remarkably high off the back of a MaskOfSanity, a powerful adoptive parent, and a couple of things he's genuinely good at (like piloting HumongousMecha), but most of the second season consists of the rest of the cast learning how little there is to him underneath it all... often after they'd invested way too much in his supposed competence.
127* Machina of ''Manga/HayateTheCombatButler''. He nearly kills Hayate, even stating it wouldn't be murder, and later on he turns into a [[OneWingedAngel giant snake]]. He also gets very excited when his master gives him money to get something to eat and orders 100 hamburgers all at once.
128%%** The main character's parents, with heavy emphasis on manchild.
129* The "Vampire" Clair Leonelli from ''Anime/HeatGuyJ'' is a MadBomber who speaks very childishly (referring to his dead father as "Papa", for example), is prone to violent temper tantrums, and is described by one character as liking to "play with" his enemies before he kills them. He does have a FreudianExcuse, though, and his childishness is designed to make him seem fragile and sympathetic as much as it's used to make him frightening.
130* ''Manga/{{Hellsing}}''
131** With the color guard-esque shenanigans with her musket, her cheerful pink alarm clock, her yellow parasol, and general squee-ing personality, Rip Van Winkle comes off less like a vampiric monster and more like a ''really'' chipper 13-year-old who's totally excited about this whole Nazi thing. Creator/TaliesinJaffe compares her to a vicious child in a nursery rhyme, in the way she talks ("Tinker, tailor, soldier, sailor"), her general cheerfulness in her psychosis, and how she seems to have an almost Little Red Riding Hood-esque naivete in just what she's getting herself into, happily believing herself a "hunter" just like in her favorite opera despite knowing what happens to that hunter in the end. The latter is especially prominent when she is in essence [[spoiler:devoured by a big bad wolf]].
132** [[spoiler: Alucard points out that Walter C. Dornez never truly grew past his teenage years of wanting to prove himself to be better than anyone else. Walter simply couldn't stand the idea of fading away by old age when he knew he had the resources to rejuvenate himself and go out with a bang.]]
133** Jan Valentine's a bloodlusted punk who functions roughly on the same level as an adrenaline-fueled teenager. He also dresses like a chav youth despite being an adult.
134* ''Webcomic/HetaliaAxisPowers'':
135** [[NationsAsPeople Russia]] started off as a [[UsedToBeASweetKid genuinely nice kid who just wanted friends]]...[[FreudianExcuse then his brutal childhood and history of bullying, tragedies, wars and forced servitude cracked his mentality to become this]]. Now as an adult, he's extremely powerful and still has all the innocence and cruelty of a child. He desires friends as much as he did when he was little, but now he's [[ManipulativeBastard manipulative]], self-centered, [[{{Yandere}} aggressively possessive]] and just plain creepy. He masks both his pain and insanity by [[StepfordSmiler smiling]] and [[CuteAndPsycho acting sweet and nice]] until he gets ambitious, or something pisses him off, and he switches moods at the drop of a hat. He has also found amusement in tormenting those weaker than him and watching the other nations fight. Therefore, he classifies, though not villainous.
136*** However, this is ''horribly'' [[{{flanderization}} flanderized]] in the fandom. In the canon strips, he says creepy things and stalks people from around corners but has only actually done anything a ''handful'' of times, and none of it was sexual (except ''possibly'' the time he put Lithuania in a French maid outfit and whipped him while he was working). But many fans tend to make Russia [[RonTheDeathEater a bratty, smug, rapist bastard]] without any good traits that would put Stalin to ''shame''.
137** And then there's Russia's younger sister Belarus. ([[TeamMom Poor Ukraine]] deals with ''two'' of these!) Now a beautiful young woman, but mentally, she's the same [[PerpetualFrowner grumpy]], [[ClingyJealousGirl easily jealous]] little girl who would cling to her big brother at all times, only now she's [[BigBrotherAttraction so attached and obsessed]] [[BrotherSisterIncest that she's madly in love with Russia]], and [[{{Yandere}} pressures him to marry her]] in the most violent, persistent, and creepy ways. She's one of the very few nations that can intimidate him, but she mostly stays by his side to intimidate others to do what Russia wants. She's sheltered, throws temper tantrums, is very blunt and [[SirSwearsALot uses profanity]] [[ObligatorySwearing like a kid looking for attention]]. She usually dresses like she's young, in an ElegantGothicLolita dress Russia gave her. She was also described as being like a "little sister" figure to America at one point, despite being much older than him, and America being quite the ManChild himself.
138** America tends to [[RonTheDeathEater get this treatment]] when he shows up in {{Dark Fic}}s, and to some extent his LeeroyJenkins tendencies in canon can come off slightly this way, especially in the dub.
139--->'''America''': I think it makes use of our strengths in the best way possible! Britain [[LeeroyJenkins goes in suicidal]] -- it's your Charge of the Light Brigade routine! France [[CheeseEatingSurrenderMonkeys gives up without a struggle]]! And for Russia, just keep [[WeHaveReserves sending us your cannon fodder]]! You'll draw the guns away... from me!
140* In ''Manga/{{Inuyashiki}}'', BigBad & SerialKiller Hiro Shishigami is a [[TheSociopath sociopathic]] {{Otaku}} who feels a strong attachment to fictional characters and talks casually about them even as he's committing horrible atrocities, and while he knows what he's doing is legally wrong, [[EvilCannotComprehendGood he doesn't truly understand why]]. When choosing houses to enter, he spins around like a child playing a game before pointing at one and saying "You're it". His one redeeming quality is that he's a MommasBoy [[EvenEvilHasLovedOnes with his parents, girlfriend, and singular friend being the only people in the world]] safe from his wrath.
141-->'''Victim:''' Are my father and little brother dead too?\
142'''Hiro:''' [[LaughablyEvil What does that matter?]] We were talking about ''Manga/OnePiece''.
143* ''Manga/JoJosBizarreAdventure'':
144** ''Manga/JojosBizarreAdventureDiamondIsUnbreakable'': Despite having an IQ of 160 according to Jotaro and being 35 years old, SerialKiller [[StarterVillain Anjuro "Angelo" Katagiri]] acts less his age and more like a spoiled-rotten, heartless and sociopathic 2-year-old crybaby, what with him [[DepravedBisexual raping teenage boys and women indiscriminately]], doing unthinkably heinous crimes [[CreepyChild since the age of 12]] that even '''ComicBook/TheJoker''' [[EvenEvilHasStandards would find utterly disgusting]], treats his crimes as [[ForTheEvulz nothing more than a childish game]], does things on a whim and, what seals the deal, is his [[EvilIsPetty attempt of murdering Josuke for interrupting his planned robbery]] which is nothing but a deranged tantrum he throws and, out of spite, plans to rape Josuke's mother Tomoko, his [[DirtyCoward extreme cowardice]] and [[NeverMyFault pathological inability to acknowledge his atrocities]] as shown in the film and his DisproportionateRetribution towards dog owners who allow their canine companions let their poop near him, coming across as a child breaking his own toys. This is all that makes him [[HateSink that much more loathsome]].
145** ''Manga/JojosBizarreAdventureStoneOcean'': Jolyne's cellmate [[StarterVillain Gwess]]. Upon first meeting her she attempts to [[MoodSwinger brain Jolyne with a chair in a fit of rage]] after she mistakenly attempts to use her bunk before doing a full 180 and acting friendly, and treats her [[IncredibleShrinkingMan shrunken victims]] like [[LivingDollCollector a girl playing with stuffed animals]], having them do cutesy animal sounds in the "costumes" she makes for them. She also [[YouHaveOutlivedYourUsefulness has them killed when they stop being of interest to her]]. Her ability is [[PersonalityPowers explained as a manifestation of her desire]] to [[FriendlessBackground make friends]] [[ControlFreak but have power over them]]. She's so hopelessly insane that Jolyne breaks the longstanding DefeatMeansFriendship tradition and keeps her at arm's length.
146* Akura-Ou from ''Manga/KamisamaKiss''. One minute he is playful, happy and silly... the next minute he will brutally kill dozens of people for the most trivial of reasons.
147* Nova, Hikaru's EnemyWithout from ''Manga/MagicKnightRayearth's'' second season. She just wants to be loved by Hikaru...and by that, we mean [[PsychoLesbian cover her friends in large pools of blood so that only the two of them can "play" forever and ever]].
148* The Eleven Scars in ''Manga/MobPsycho100'' are all immensely powerful psychics, believing that their powers make them [[AGodAmI worthy to rule and be worshiped.]] The main characters, who all subscribe to AGodIAmNot, face them and either subject them to a CurbStompBattle from Mob, Ritsu, or Teruki or a [[BreakThemByTalking verbal smackdown]] from [[GuileHero Reigen]]. [[spoiler:When the leader Ishiguro gives a MotiveRant, sans mask, his art shifts meaningfully to the point that he looks like an infant... which is fitting, since, without his mask or a voice changer, his rant about [[IJustWantToBeSpecial wanting everyone to pay attention to him and praise him for how great he was]] is so childish as to be infantile.]]
149* Johan Liebert of ''Manga/Monster1994'' is a classic example. His goals and desires are highly simplistic, but as an adult, he pursues them with an appropriate level of sophistication. Exactly how childish he really is can be hard to judge given that he's an excellent manipulator.
150%%* Michio Yuki, the VillainProtagonist of ''Manga/{{MW}}'', is either type C or D.
151* Gozaburo Seto of ''Manga/MyBrideIsAMermaid''. While he's the boss of the Seto Clan and threatens Nagasumi, his wife Ren still sees him as a spoiled, immature brat who never left middle school and it shows. Sun even [[CallingTheOldManOut calls him out on it]] in the second episode ("I can't respect a father who won't even act like a man!").
152* ''Manga/MyHeroAcademia'':
153** Tomura Shigaraki, one of the central antagonists, straddles between types B and C while playing this to the hilt; to the point where several other characters actually refer him as such. Even his comrades and the villains he tries to win to his side make note of his immaturity, his impulsiveness, and the tantrums he throws when he doesn't get his way.
154** There's also one of his underlings, Himiko Toga. While she blushes and swoons like a fangirl when talking about somebody she likes and gives people childish nicknames like "Mr. Handsy" and "Stainy"; she's also an accomplished serial killer with a blood fetish. [[spoiler:The latter is arguably justified, as that's how her Quirk works.]]
155** Another one of Shigaraki's underlings, Dabi, is revealed to be this. For most of the series, he seems like the most level-headed member of the group with his goals shrouded in mystery. Durng the WarArc, he reveals his true colors [[spoiler: as Endeavor's thought-to-be-dead son and absolutely loses all composure as he rubs it in his father's face, to the point of dancing. His motives stemming from years of neglect and a desperate need to get his father's attention all but cement that he's essentially a destructive, angry 13-year-old teenager all grown-up.]]
156** The biggest one, however, is [[BigBad All for One]] himself. Underneath his calm, collected and calculating exterior, this man is essentially a petulant child all-grown up, [[ExaggeratedTrope being even more childish than Tomura, Toga and Dabi combined]]. For starters, his goals of becoming an all-powerful demon king is [[spoiler: nothing but a childish fantasy derived from a manga he and his brother used to read as kids]], does atrocities on a whim [[ForTheEvulz for the hell of it]], treats said atrocities like a kids' game, is [[ItsAllAboutMe childishly selfish]], and the ultimate selling point are his {{villainous breakdown}}s. He has one first on the Star and Stripes Arc, during which he reveals his true colors as a SoreLoser and has a hissy fit, then a second one being when Jiro and eventually Tokoyami destroy his mask, where his feral meltdown is almost exactly like that of a bawling crybaby breaking his toys in a feral manner. And to really sell it, there's [[RuleOfThree the third one]], when Deku overpowers his [=TomurAFO=] form and All for One ends up throwing a violent high-octane childish tantrum.
157* ''Manga/{{Naruto}}'' has a mixture of villains who act mature and others who act like kids (or, once again, both), though to be fair the same is true of the heroes.
158** Tobi [[spoiler:aka Obito]]. Depending on the viewpoint, his goal is either childish or overly idealistic: [[spoiler:He wants to replace reality with a dream where everyone can be happy, and the good guys always win.]] The psychopathic part comes from the fact that he is willing to kill lots of people to accomplish this, as he reasons that they will be resurrected anyway once he accomplishes his goal.
159** Madara Uchiha is incredibly powerful, head of his clan, co-founder of the Hidden Leaf, and the shinobi village system. His offence over not being declared Hokage was also rather disproportionate, though it should be noted that he has more complicated (perhaps even understandable, though not justifiable) motivations than just simply that. [[ArsonMurderAndJaywalking Also, he is extremely cocky.]]
160*** [[spoiler:And that's not to mention the fact that he acts like a child with a new toy when it comes to the Ten-Tails Beast, as well as when he's fighting Eighth Gate!Gai. Obito even calls him out on his behavior with the former! In the case of the latter, when he sees a surge in Gai's power, in some translations he calls out: "All right, I'm game! I'll play with you!"]]
161** [[spoiler:Black Zetsu's whole motivation in a nutshell can be described as the desire to be reunited with his mother and he doesn't care that this causes suffering for a lot of people because they are only part of the story which he created for the revival of his mother. Naruto even lampshaded this, calling him a child clinging to his mother's side even after millennia of living.]]
162* King Hamdo from ''Anime/NowAndThenHereAndThere'' is a power-hungry ruler (with more than a passing resemblance to certain African dictators) who throws tantrums and calls for his assistant Abelia to comfort him when things go wrong. He thinks little of human life and often laughs maniacally. Ironic, considering he forces [[ChildSoldiers actual children to kill and die for him]].
163* In ''Manga/OnePiece'', [[TheHero Monkey D. Luffy]] is your typical {{Shonen}} childish IdiotHero. So what happens when you [[spoiler: remove his shadow and create a hundred-foot-tall monstrosity with it, using the body of an ancient demon warrior]]? Oars has all of Luffy's idiocy, childlike naivety, and personality, with none of the tempering kindness and concern for friends.
164** The Demon Guards of Impel Down, four bizarre Zoan users seem more animal than man but like to goof on each other and cower whenever their officer Sadi-chan is angry like them like children to an angry mom. They are also extremely sadistic, and love to brutalize prisoners.
165** One of the newest members of the [[PsychoRangers Blackbeard Pirates]], [[spoiler:Sanjuan Wolf]] seems to apply. In his past, he was a Pirate who committed crimes "so atrocious they were effectively erased from history itself", a bounty likely to be in the upper multi-millions, and when caught offscreen, was transferred to the lowest level of [[TheAlcatraz Impel Down]], and to earn his freedom from there, was [[spoiler:forced to kill everyone in his cell on orders from [[EvilCounterpart Marshall D. Teach]] and co.]] Also, he is the largest man alive in the series, easily dwarfing Oars at least four time over, and is compared to a walking Sears Tower. But, in his first appearance, he [[spoiler:peeks out from Marineford HQ's main building like a curious child, has an expression like he was caught stealing from a cookie jar when spotted by Mooks, expressed surprise that a Vice Admiral knew his name, and was scared by Whitebeard and hid while the rest killed him.]]
166*** His classic "They found me!" line, which is all the more hilarious when you look at this [[http://img211.imageshack.us/img211/4434/juanwolf2.jpg size comparison pic]]: yes, the circled person is one of the regular giants.
167** Later chapters in the Dressrosa arc reveal [[spoiler:Doflamingo]] to be this. His despicable nature and cruelty, along with his desire to "destroy this world" are simply him being the SpoiledBrat he was as a kid and throwing a temper tantrum over the fact that he didn't get what he wanted, [[spoiler:being denied his "rights" as a descendant of the twenty kings who found the World Government by the other World Nobles because his father happened to be one of the few sane people in Mariejois and left the city with his family to live the commoner life]]. Despite all his rants about being an adult who doesn't have time to play Luffy and Law's "kiddy games," it's blatantly obvious that despite being so world-weary, he hasn't really matured at all from when he was a kid.
168** Charlotte "Big Mom" Linlin is a grown-up woman who loves to have tea parties with delicious sweets and baked goods. Wouldn't seem so bad except she's willing to decimate whole islands for wedding cake ingredients alone with little room for compromise. Case in point, willing to destroy Fishman Island since they couldn't deliver their allotted candy despite the machinery being destroyed during Hody's attempted coup and them willing to continue the order once it's fixed. Plus, likewise threatening to kill people who don't come to her parties and singing, and dancing about said tea parties with lyrics that the strawberry jam can be the usual or be made of people's blood. And if that wasn't enough, she suddenly goes on a rampage ''not long after singing this song'' and begins eating anything she can get her hands on, just because there was a certain sweet, she wanted to eat and didn't have it. Even [[spoiler:taking years from the lifespan of one of her sons]] when he tries to calm her down, all because she's too enraged to listen to reason until she finally gets it. Just... Yeesh. What's worse is that these rages are completely unpredictable; even she doesn't know when she's going to get a craving, or for what, and they ''always'' manifest without warning.
169** Shogun of Wano, Kurozumi Orochi is nothing but a violent selfish brat of a grown man with little patientence for anyone and will throw tantrums over the smallest amounts of insults. He's completely incapable of showing any kindness or honor towards anyone and will resort towards murdering anyone who he feels is a threat, even if it is a child. His execution of Oden is a prime example of his lack of honor. Despite agreeing to spare Oden and his men if Oden were to survive an hour in the boiling oil, Orochi never honors the deal and decides to execute them all regardless while laughing at them for thinking he would honor it. Ashura Doji outright refers to him as a very immature man who's making childish excuses.
170[[/folder]]
171
172[[folder:P-Z]]
173* Vincent Nightray from ''Manga/PandoraHearts'' might as well be the king of this trope due to his nasty habit of slicing up dolls with scissors and [[spoiler:causing the tragedy of Sabrie]]. There's also the Will of the Abyss, a whimsical and childlike being that rules over the hellish alternate reality of the Abyss. She veers wildly between moods, acting like an innocent little girl one moment and casually plucking a man's eye out the next moment. [[spoiler: It's because she once shattered her own mind and memories to protect her sister and Oz, leaving her completely insane]].
174* Jack Winslow of ''Anime/PowerStone'' is a [[ReallySevenHundredYearsOld really 100-year-old]] crazy who was orphaned at a young age and lost at sea. Lack of human contact might explain his behaviour.
175* Kirika Kure of ''Manga/PuellaMagiOrikoMagica'' is completely unfamiliar with the concept of maturity. Among other things, she throws tantrums at a moment's notice and drinks her tea with enough sugar to make it into syrup. She's also hunting down and killing [[spoiler: other magical girls.]] Although her motive for doing so is because she was asked to by [[spoiler: Oriko]], whom she is [[{{Yandere}} obsessively in love with]], rather than her childish tendencies. (Then again, [[spoiler: killing others because Oriko tells her so]] could be seen as childish too, as she does so to please said person and get praise from them than of her own will.)
176* The villain in the second episode of ''Manga/PumpkinScissors'' shows signs of this, in that he kills the people in his charge as part of a fun game and is hinted to be capricious to the people in his court.
177* Akio, the primary villain of ''Anime/RevolutionaryGirlUtena'', is an interestingly high functioning take on this. Outwardly, he's dapper, affable, and debonair. [[BitchInSheepsClothing Underneath that]], he's a scheming ManipulativeBastard with grandiose plans who's all but stated to be a rapist. But underneath ''that'', it becomes apparent that despite looking in his 20s and [[ReallySevenHundredYearsOld evidently being far older than that,]] he's ultimately just a hedonistic SpoiledBrat who's picking on people smaller than him and treating them like toys, as a kind of childish ideal of the big-man-on-campus, refusing to learn a lesson or mature. According to the creators, this is even why he's associated with [[CoolCar a fancy-looking red corvette that he enjoys riding on the hood of]]; a car like that, for all its power, is ultimately just a big expensive toy for a guy who never grew up. (It's not like he can actually drive it anywhere.)
178* ''Manga/RosarioPlusVampire'':
179** Gyokuro Shuzen is a powerful and beautiful vampire and the one-time matriarch of the Shuzen family... whose EvilPlan is nothing but her throwing a temper tantrum because she was insanely jealous of the fact that [[spoiler: her husband Issa loved his mistress Akasha Bloodriver more than her]]. ''Everything'' Gyokuro does throughout the series (joining [[FarEastAsianTerrorists Fairy]] [[ANaziByAnyOtherName Tale]], trying to KillAllHumans, etc.) is her way of [[spoiler:spiting the long-dead Akasha]].
180** Mizore and Kurumu's respective mothers, Tsurara and Ageha, are given this treatment in ''[=Capu2=]'', having held a grudge against each other since high school over a boy they both had feelings for (who didn't even like either of them back), and using their daughters' relationship with Tsukune as an excuse to continue their old feud.
181%%* Sojirou from ''Manga/RurouniKenshin''. At least until [[spoiler: his HeelFaceTurn]], when his whole personality acquires something of a shift...
182* In ''Anime/SailorMoon'', all of Queen Nehellania's motives (fear of aging, revenge on Helios for not being able to have him, murderous jealousy against Sailor Moon for having what she doesn't) stem from her stunted maturity.
183* Ni Jianyi's pupil who is only known as Kami-sama in ''Manga/{{Saiyuki}}'' is a sadist who loves to toy with people while pleasantly torturing them (evident by "helping" Goku get rid of a pendant ball embedded in his leg). When the Sanzo group stormed his castle, he played games with them as if they were in an amusement park. They eventually found him in his room surrounded by stuffed animals [[spoiler: which were actually the souls of people he had stolen]]. And once he started to lose, he threw a temper tantrum.
184* [[ExpendableClone Eva-R and Eva-Q]] in ''Seikon No Qwaser'' are [[HappinessInSlavery conscious of and delighted with being playthings]], meant to suffer and die for Eva Silver. And yet in a backwards way, they regard any prospective dominant (i.e., anyone they look at) as their plaything, and are quick to break any 'toy' who isn't breaking ''them'' to their satisfaction.
185* Exaggerated in ''Manga/{{Servamp}}''. Tsurugi is a pretty on point example. For starters, while doing paperwork, Tsurugi rarely does actual work and prefers to frantically beg for forgiveness and often does origami with the sheets. When he does do the work, he writes it entirely in hiragana as a small child would. In a chapter where he's shown eating dinner, he has his legs brought up next to him and when he's finished, he leaves what appears to be food all around his plate as though a toddler had been eating there. A little more on the scary side is that due to his magic causing him to become unstable (if he wasn't already), Tsurugi becomes unable to remember if he is either seventeen or twenty-three when his real age is twenty-six. He also is fond of giving everyone nicknames, mainly by shortening their first name and adding the suffix 'chan'. Tsurugi has been shown to enjoy pranking people in dangerous ways, such as climbing into Mahiru and Kuro's room, jumping onto their table from an air vent and suddenly pointing guns at them. When [[spoiler:The Mother invites him to become her eve, he suddenly begins crying like a kid]]. Later, his spirit exits his body and takes the shape of a small boy, referencing his mental state. Just remember, he is one of the most dangerous C3 magicians who regularly shows little concern for others and loves fighting vampires.
186** Tsubaki also has this, but not to the extent of Tsurugi. He's known to laugh hysterically at random things before abruptly calling them boring. His subclass Berukia also takes the form of a doll.
187* ''Anime/ASilentVoice'': Naoka Ueno. Even though she is 18 years old, it's clear she retains her childish mindset from grade school. She ridicules and humiliates Shouko, throws temper tantrums when she doesn't get her way, doesn't take responsibility for her actions, and refuses to move on from her past friendship break up. She finally overcomes this by the end of the manga, though [[AdaptationalJerkass not so much in the film version]].
188* [[spoiler: Kishin Asura]] from ''Manga/SoulEater'' has this side to him, although it only really shows during [[spoiler: his final [[VillainousBreakdown breakdown]] in the anime.]]
189* ''Literature/SwordArtOnline'':
190** Akihiko Kayaba trapped thousands of people in a virtual world of his own making with no way to log out other than to clear the game, [[spoiler:walked among them as a player and rallied several of them around himself in one of its most powerful guilds, with full intention of betraying them as the game's FinalBoss,]] and made it so that anyone who died in the game was KilledOffForReal. [[spoiler:In his final conversation with Kirito and Asuna, he reveals that he did this all so that the imaginary play world that he always dreamed of would be as real as he could possibly make it. He also seems to be oblivious to the moral and ethical implications of his actions, to the point where the fact that he is responsible for the deaths of 4,000 people is simply an abstract statistic to him.]]
191** Sugou Nobuyuki, the main villain of the Fairy Dance arc, is arguably even worse than Kayaba, but with none of Kayaba's redeeming qualities. While he can put up a respectable front, BeneathTheMask Sugou is a physically weak, morally spineless coward who just wants to slobber all over Asuna, both in-game and over her comatose body in real life and throws temper tantrums when he doesn't get his way. Best shown when Kayaba's VirtualGhost overrides his control of the game and gives Kirito admin privileges; Sugou whines and throws a tantrum, griping about how even in death, Kayaba's getting in his way and taking everything that Sugou considers rightfully his. Immediately afterwards, when Kirito gives him a small cut on the cheek with the Pain Absorber set to 0, Sugou has a minor FreakOut and [[MinorInjuryOverreaction whines over the pain]] like a child with a scraped knee. Made even more blatant in the original Japanese; Sugou [[UsefulNotes/JapanesePronouns uses the gentle-masculine "Boku"]] (normally used by little-boys) to refer to himself (instead of the coarse-masculine "Ore" or gender-neutral "watashi" expected of a grown man), further accentuating that beneath his MaskOfSanity is a pretentious SpoiledBrat.
192** While Gabriel Miller never displays any behavior that would suggest this, the fact that his power to see souls and consume them in the Underworld stems from the delusional belief that he's actually capable of doing just that and that he's had this belief since ''childhood and has never grown out of it'' certainly implies that he is one.
193* Kano from ''Anime/{{Texhnolyze}}''. He's eloquent, intelligent and charismatic, but that doesn't change the fact that he sees the world as one big playground, and himself as the only real person in it.
194* ''Manga/TokyoGhoul'': Yakumo "Yamori" Oomori/Jason has shades of this on top of being a TortureTechnician who enjoys making people suffer. When his SadisticChoice to Kaneki fails, Yamori whines and throws a temper tantrum before killing both his hostages, after which he slaps Nico and storms out while blaming him for ruining his fun. After Kaneki beats him and leaves him to the CCG's mercy, he repeatedly cries out for his mother to help him.
195* 15-year-old [[NobleDemon Manjiro "Mikey" Sano]] in ''Manga/TokyoRevengers'' is the strongest character in the series, and a sadistic CreepyChild who manages to start a massive gang of JapaneseDelinquents encompassing multiple schools with total control of Shibuya, despite being in his mid-teens and half the size of his subordinates. One day he'll order his men to go to war against a rival gang to avenge one of their own, the very next he'll be throwing a fit in a restaurant because they forgot the flag in his kid's meal and falling asleep after.
196* ''VisualNovel/UminekoWhenTheyCry'': the Stakes of Purgatory seem to have some elements of this. Oh no, [[ColdBloodedTorture their new toy broke...]]
197** Depending on how you interpret the series, you could probably include Beatrice, Eva-Beatrice, and Erika in this trope. All the witches except (maybe) Virgilia are prone to ImmortalImmaturity, [[spoiler:though in Lambdadelta's case her childish behaviour is just an act, and Beatrice is later revealed to be only 19 years old and not [[ReallySevenHundredYearsOld a thousand]] as she claims. Though when you take her upbringing as [[AmbiguousGender Yasu]] into account, you can't exactly blame her]]. Maria gets excused because, well, she ''is'' a little girl.
198* Dilandau Albatou of ''Anime/TheVisionOfEscaflowne'' fame, the spiritual predecessor to Clair above, might be an even more obvious example, as when he's not fighting, he spends much of his time throwing fits and having nervous breakdowns over things that range from [[DarkAndTroubledPast understandable]] to [[MinorInjuryOverreaction entirely]] [[HairTriggerTemper petty]].
199* Jeremy Agriche of ''Literature/TheWayToProtectTheFemaleLeadsOlderBrother'' attacks, beats, maims and kills people over slightest perceived infractions, only to later run back like an excitable puppy to his beloved older sister for headpats and praise.
200* Jakotsumaru from ''Anime/YashahimePrincessHalfDemon'' qualifies for this. He's acting like an angry, irritable teenager for most of the episode. To be fair, it's not known how old he actually is, and he looks pretty young too. Still, it is noticeable that he is a villain with remarkably immature demeanor.
201* Pegasus J. Crawford / Maximillion Pegasus from ''Anime/YuGiOh''. He steals people's souls (including a small child's), tries to take over a company by killing the CEO and pursues Ancient Egyptian artifacts with no regard for anyone in his way, all to bring his wife BackFromTheDead. In his spare time, he watches cartoons and loves them to the point that he creates a ''deck'' based around them. [[SchrodingersCast In the anime]], he [[HeelFaceTurn becomes a good guy]] later on, though.
