"Like I said, kids are cruel, Jack. And I'm very in touch with my inner child."
A dangerous villain or a brutal Anti-Hero
, either a teenager or an adult, with a childlike nature
, which creates a dissonance between innocence and savagery. Such characters can become rich sources of Nightmare Fuel
, especially if their childishness is never explained. Contrary to the term, many examples are not necessarily psychopaths in the clinical sense. Misaimed Fandom
may not be out of the question, either; sometimes the character's more "Moe
" attributes will be picked up on and subjected to Flanderization
The exact extent of the character's childishness will vary, and in general Psychopathic Manchildren can come in several varieties, with possible overlap. Such a character may:
- Type A: Be big Dumb Muscle, frequently mentally-challenged, that operates under someone else's direction. This type may be the most common, and also the most likely to play to the audience's sympathy. Expect him/her to try to Pet the Dog, often with disastrous results. Could be a subversion of Dumb Is Good.
- Type B: Seem superficially powerful and cruel, but have very childish or simplistic goals, motivations or world views. May overlap with One of the Kids—if the cruelty part isn't played up to horrifying levels.
- Type C: 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 advertise that there is something seriously wrong with him/her, to make him/her creepier. These are most likely to be a story's Big Bad.
- Type D: This one is a literal example: Appear cute and harmless on the surface, but actually be this trope. Especially common with female examples, because of the stereotype.
- Type E: Be subject to a personal variation of Values Dissonance where violent, savage actions are viewed by the character in question in the same light as regular play is viewed by most real children. This variant is often an especially strong source of Nightmare Fuel due to the uncanny dissonance between his/her childish demeanor and the viciousness of his/her actions.
- Type F: Be completely or largely inexplicable, and the discrepancy between the different parts of their personality Played for Laughs.
Whichever version these types of characters qualify as, often they are not fully aware of how nasty their actions actually are. In some cases (though not all), a Heel Realization
may cause the character to develop into a better person.
A more innocent or well-intentioned Psychopathic Manchild may be a Noble Demon
One way to use this character is to face him off against a jaded
, or shady Anti-Hero
, to play with traditional hero-villain relationships by making the villain more innocent than the hero (at least in theory). (Easier if he's a major villain in his own right.) Another interesting twist is to make this character the Designated Hero
and match him with an Affably Evil
When one of these is running a country or occupying a similar position of authority, you have The Caligula
The grown-up equivalent of Creepy Child
and the near-inversion of Enfante Terrible
. Contrast with Sociopathic Hero
and the typically more benign Man Child

Anime and Manga
- Johan Liebert of Monster 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.
- Tongpu from the Cowboy Bebop episode "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 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 "there is nothing so pure and cruel as a child". His reaction to Spike's attack is the first time we truly grasp just how far back he's gone.
- 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.
- Priscilla may count too, at least until she awakens.
- The Devil Is a Part-Timer!: In his first appearance, Lucifer reveled in the screams he caused and treated the entire fight with Maou and Emi as a big game as he destroyed everything around him.
- Gluttony from Fullmetal Alchemist is a ridiculously strong Artificial Human with the temperament and intelligence of a young boy. 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). When she dies, the poor guy suffers a nervous breakdown.
- King Hamdo from Now and Then, Here and There 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.
- Mao from Code Geass, 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 More Than Mind Control he engages in...
- It's even more obvious in the supplemental reading, in which he is, in a word, so innocent that he manipulates and kills people with evil impulses to stop them from hurting his beloved C.C..
- 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.
- Nova, Hikaru's Enemy Without from Magic Knight Rayearth's second season. She just wants to be loved by Hikaru...and by that, we mean cover her friends in large pools of blood so that only the two of them can "play" forever and ever.
- Axis Powers Hetalia:
- Russia started off as a genuinely nice kid who just wanted friends...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 manipulative, self-centered, aggressively possessive and just plain creepy. He masks both his pain and insanity by smiling and 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.
- However, this is horribly 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 take this trope Up to Eleven and make Russia a bratty, smug, rapist bastard without any good traits that would put Stalin to shame.
- And then there's Russia's younger sister Belarus. (Poor Ukraine deals with two of these!) Now a beautiful young woman, but mentally, she's the same grumpy, easily jealous little girl who would cling to her big brother at all times, only now she's so attached and obsessed that she's madly in love with Russia, and 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 uses profanity like a kid looking for attention. She usually dresses like she's young, in an Elegant Gothic Lolita 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 Man Child himself.
- America tends to get this treatment in Dark Fic he shows up in...
- Dark Action Girl Nena Trinity from Gundam 00 is an excellent Type D. She's 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 Artificial Human 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 did she do that.
- In the side materials, it's strongly implied that there's a pretty good reason for this: seventeen-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. She's basically a little girl in the body of a teenager; such stuff does a LOT in the mental/emotional maturity of anyone.
- Wong Yunfat from G Gundam is one of the rare Magnificent Bastard versions, as well as a Type C. He loves eating chocolate and is seen in his pajamas as well as leaning on a giant teddybear at one point, and some of his reactions to being in a disadvantage can be seen as very childish... but Wong's own cunning plans and back-up plans make him far smarter and more ruthless than the average PSM.
- Rosamia Badam from Zeta Gundam. She's a Type D as well, but in different terms: she's a 17-going-to-18 year old Dark Action Girl who, outside her mecha, has the mentality and the fears of a little girl, latches innocently on whoever she sees as a Replacement Goldfish for her dead older brother, and is borderline 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 Colony Drop of the One Year War, which happened when she was a little girl, but was subjected to cruel experiments that messed up with her mind even more.
- Gundam SEED has Muruta Azrael, a psychopathic genocidal maniac, motivated entirely by childhood grudges, and possessing the maturity level of a particularly vicious teenager.
- Gundam SEED Destiny has Rosamia's even more handicapped expy, Stella Loussier, who while veyr efficient in combat, is a five 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, attacks anyone who tries to approach her) can be driven into a breakdown by the mention of his mother.
- Renge in the Flame of Recca 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 fusing with Tendou Jigoku looks EXTREMELY COOL. She doesn't end really well.
- 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.
- Dragon Ball:
- Fat Majin Buu from Dragon Ball Z is Type A - he has no idea that what he's doing is wrong, and is single-handedly converted to good by Hercule / Mr Satan. Super Buu is type C; he sounds increasingly intelligent once he starts absorbing people, but still throws tantrums when he's outmatched. Kid Buu, who doesn't have any desires that don't involve blowing things up, is Types C and E put together.
- Broly is somewhere between Type B and Type C, arguably. His motivation to kill Goku? Goku's nonstop crying scared him and kept him awake for days on end when they were babies in the same "nursery."
- Emperor Pilaf acts like a Spoiled Brat and throws temper tantrums when he doesn't get his way.
- Chilled from the Gainax manga 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.
- Android #17 is Type B. Even more so (in fact a cross between B and E) in the Bad Future 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. When Future Trunks shows up and she wants to kill him to blow off steam, #17 said 'ok, we can, but we'll miss out on weeks of fun playing with him', treating it more like a game than their nemesis. Trunks actually calls him out on it before killing him.
- General Blue technically qualifies. Although he has 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.
- There's also Recoome of the Ginyu Force, though he might simply put on this air to taunt his opponents.
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 Frieza who also love to make very hammy Sentai poses to introduce themselves to friend and foe alike and decide things via rock/paper/scissors.
- Even Frieza gets to have traits of this. Usually behaves in a manner similar to that of a spoiled child. The most notable example is when he comments in hell about Goku fighting with Kid Buu.
- 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. After being forcibly reverted to this form by SS2 Gohan, his response is to throw a massive fit and to try to blow himself up, taking the entire Earth with him.
- Beerus, the Big Bad of Dragon Ball Z: Battle of Gods. While incredibly powerful, to the extent that he can curb-stomp Super Saiyan 3 Goku with 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 King Kai's original planet simply because King Kai 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.
- Misa Amane from Death Note is Type D- an endearingly naive Kawaiiko who has a very childish demeanor that persists well into her 20s, obsesses over fashion like any young girl, is completely boy-crazy, and was able to translate her Moe Moe appeal into a successful career 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 human life has an intrinsic value beyond being useful to Misamisa-chan, who latched on the man who used his Death Note to kill the burglar years after the actions that shattered Misamisa's mind. The results weren't pretty.
- It's possible that she was just a nice, cute, but immature young woman at least partially driven insane by the Death Note. Given Light Yagami's flying leap off the slippery slope from an idealistic young man who thought he was doing the right thing to a maniacal tyrant willing to kill anyone and anything to further his raging god complex and Teru Mikami's astonishingly short break from a focused, serious lawyer with an inhumanly high standard of justice to a barely coherent Ax-Crazy psychopath, it's not too hard to imagine that the Death Note has an unspoken With Great Power Comes Great Insanity rule that Misa was affected by. For example after she permanently gives up the Death Note, she's completely harmless and probably quite fun to be around, unless you're Takada.
- Light himself qualifies as Type C (flirting with D). 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, and L specifically identifies 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 for insulting him on national television and his need to gloat to L and Near when he thinks he's beaten them. His Villainous Breakdown at the end takes the form of a blatant childish fit.
- Ryuk is type B-a cruel monster who sets everything off because he's bored.
- Umineko's Stakes of Purgatory seem to have some elements of this. Oh no, their new toy broke...
- 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 Immortal Immaturity, 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 a thousand as she claims. Though when you take her upbringing as Yasu into account, you can't exactly blame her. Maria gets excused because, well, she is a little girl.
- Wonderweiss Margela from Bleach fits pretty well. He can't even speak coherently, but heaven help you if you don't let him play with your hat or aren't Yamamoto. Technically he's a Type A - under Aizen's full control, appears to have limited understanding of his actions, will attack Aizen's opponents, but seemingly at random with no real indication he's enjoying the violence as such.
- Domu: A Child's Dream, one of Katsuhiro Otomo's lesser-known works, features Old Cho, a powerfully psychic but senile old man whose 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. You do not want to be present when this happens. Fittingly, the one who actually defeats Old Cho is Etsuko, a Little Miss Badass with similar psychic powers and a Plucky Girl nature.
- Ladd Russo of Baccano! can get pretty child-like in his homicidal glee, and is usually shown skipping, babbling excitedly, dancing in pools of blood, or any combination of the three.
- In the light novels Chick and Maria are described as having the personalities of 12-year-olds. Speaking of, Chick qualifies in the anime as well.
- Ladd's Loony Fan Graham Specter may also count.
- Arguably Kano from Texhnolyze. He's eloquent, intelligent and charismatic, but that doesn't change the fact that he sees the world as a one big playground, and himself as the only real person in it.
- Diva from Blood+ is a very depraved type B. For example, in episode 24, she bites young Riku and drinks his blood, then childishly laughs and jumps around in a white and blue Pimped-Out Dress when caught by the heroes, before she captures Saya herself and almost kills her. Later, she will rape and kill Riku to impregnate herself.
- Friend from 20th Century Boys is a rare Magnificent Bastard version of this. As clever as he is, it doesn't change the fact that he is only trying to destroy the world because he never grew out of his childhood grudges.
- Machina of Hayate the Combat Butler. He nearly kills Hayate, even stating it wouldn't be murder, and later on he turns into a 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.
- The main character's parents, with heavy emphasis on manchild.
- Pegasus J. Crawford / Maximillion Pegasus from Yu-Gi-Oh!. 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 Back from the Dead. In his spare time he watches cartoons and loves them to the point that he creates a DECK based around them. In the anime, he becomes a good guy later on, though. (Ether type C or type B)
- Lucy from Elfen Lied is a mixture of types C, D (counting Nyu), and E.
- The silpelits can also qualify even though they're chronologically children because they age quicker.
- In One Piece, Monkey D. Luffy is your typical Shōnen childish Idiot Hero. So what happens when you 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 naivetie, and personality, with none of the tempering kindness and concern for friends.
- Also in One Piece, the Demon Guards of Impel Down, four bizarre Zoan users seem more animal then 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 the brutalize prisoners.
- One of the newest members of the Blackbeard Pirates San Juan 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 Impel Down, and to earn his freedom from there, was forced to kill everyone in his cell on orders from Marshall D. Teach and co. Also, he is the largest man alive in the show, easily dwarfing Oars at least four time over, and is compared to a walking Sears Tower. But, in his first appearance, he peeks out from Maineford 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.
- His classic "They found me!" line , which is all the more hilarious when one looks at this size comparison pic◊, yes the circled person is one of the regular giants.
- Later chapters in the Dressrosa arc reveal Doflamingo to be this. His despicable nature and cruelty, along with his desire to "destroy this world" are simply him being the Spoiled Brat he was as a kid and throwing a temper tantrum over the fact that he didn't get what he want, 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.
- Rip van Winkle from Hellsing is an excitable young woman who likes to sing opera beautifully and also enjoys killing things while laughing her ass off. She intends on conquering the world for Millennium.
- Vincent Nightray from Pandora Hearts might as well be the king of this trope due to his nasty habit or slicing up dolls with scissors and 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. It's because she once shattered her own mind and memories to protect her sister and Oz, leaving her completely insane.
- Jack Winslow of Power Stone is a really 100-year-old crazy who was orphaned at a young age and lost at sea. Lack of human contact might explain his behaviour.
- Chrono Crusade has Joshua Christopher, who was kidnapped by the Big Bad as a young boy and given 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 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.
- The anime also seems to treat Shader this way, by keeping her Genki Girl personality but changing her morality from a grey shade to nearly completely black, giving her a sadistic streak to boot.
- Sojirou from Rurouni Kenshin. At least until his Heel-Face Turn, when his whole personality acquires something of a shift....
- Puppetmon from 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.
- Arguably Diablomon from Our War Games. 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 creepy childish giggle.
- Yukio Oikawa from 02 is a more sympathetic example, never really maturing after he discovered the Digital World and especially after his best friend died. He finally starts growing up after he meets the father and son of his late best friend again and realizes that they must miss him even more than he does. Sadly, it doesn't matter since he's been possessed by Myotismon.
- Izaya of Durarara!!. One of the rare Manipulative Bastard 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.
- Eva-R and Eva-Q in Seikon No Qwaser are 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.
- Naruto has a mixture of villains who act mature and others who act like kids, though to be fair the same is true of the heroes.
- Orochimaru definitely has elemenets of Type C with his gleeful sadism, particularly he resurrected the first two Hokages just to rub it in his old teacher's face.
- The Type B Deidara is even worse and commits suicide just because Sasuke had beaten him and was treating him with indifference.
- Sasori is a mix of B and C. He is an insanely talented and cold-blooded Puppetmaster in his 30's, who also transferred his essence into a puppet resembling his 15 year old self, and was more or less beaten by a memory of his parents coming to hug him. Justified Trope, though: Sasori's parents were killed in battle by Kakashi's father Sakumo when Sasori was a baby and he left the Sand Village when he was around 15 years old after killing and turning the 3rd Kazekage into one of his puppets. From his broken childhood to his subsequent defect from his village, he grew cold and stoic due to the lack of parental love, despite his grandmother Chiyo's efforts. His emotions were stunted to that of an abandoned, forgotten child, and his puppet body physically reflects the age he had when he left the place he was raised in.
- Pain is a deliberate inversion however, as his villainy derives from a twisted version of Jiraiya's philosophy that growing up is based on suffering; since he has suffered so much, Pain believes that he has matured into godhood (in a non-Westernsense).
- The anime portrays Hidan as a big Type B: he's the Akatsuki version of a Hot-Blooded, foul-mouthed, smartass rebel teenager in the body of a man who looks like he's in his 30's (actual age: 22) and he'll kill whoever stands in his way bloodily and mercilessly.
- Tobi aka Obito is a Type B. His goal is extremely childish: he wants to create a dreamworld where everyone can be happy and the good guys always win. The psychopathic part comes from the fact that he is willing to kill any number of people in order to accomplish this.
- Madara Uchiha, Type C: Incredibly powerful? Check. Head of his clan? Check. Co-founder of the Hidden Leaf, and, by extent, the entire shinobi village system? Check. So why does this trope apply? The entire over-arching plot is a temper-tantrum he throws after eavesdropping on Hashirama and Tobirama Senju, in their own home, and hearing Tobirama express his opinion that the title of Hokage should be voted on by the Village Elders and Clan Heads instead of just being handed to Madara because Hashirama wants him to have it. Ironically, Madara probably could have been voted Hokage if he didn't have a history of behaving this way. Also, he is extremely cocky.
- He acts like a child with a new toy when it comes to the Juubi, as well as when he's fighting Eighth Gate!Gai. Heck, Obito calls him out on his behaviour with the former!
- Gates from Full Metal Panic! is an over-emotional Cloudcuckoolander who acts rather like a child throwing temper-tamtrums, and whose completely random actions would be hilarious if they didn't involve killing so many people.
- The villain from the second episode of Pumpkin Scissors 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.
- Chaka from Black Lagoon is introduced as a Type B. He seems like a dimwitted yet likeable mook who harbors an almost childlike enthusiasm for guns and shootouts... then said facade falls down, and we're faced with Ax-Crazy. Who's also Too Dumb to Live, as Ginji eagerly proves.
- Ni Jianyi's pupil who is only known as Kami-sama in 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 which were actually the souls of people he had stolen. And once he started to lose, he threw a temper tantrum.
- Tamaki, the Promoter of Deadman Wonderland. 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. He's also a bit of an RPG Otaku and sees the Wretched Egg as a Big Bad to defeat.
- 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 Morality Pet. Turned Up to Eleven when it comes to Hagire, who Body Surfed into him.
- Kirika Kure of Puella Magi Oriko Magica 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 other magical girls. Although her motive for doing so is because she was asked to by Oriko, whom she is obsessively in love with, rather than her childish tendencies. (Then again, 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.)
- The Big O's Alex Rosewater. "This is my Big! This is my dome! You can't have it!" Also, to an extent, Alan Gabriel.
- Haruko from FLCL.
- Amaimon of Blue Exorcist 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.
- Michio Yuki, the Villain Protagonist of MW, is either type C or D.
- Akihiko Kayaba of Sword Art Online trapped thousands of people in a virtual world of his one making with no way to log out other than to clear the game, 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 games Final Boss, and made it so that anyone who died in the game was Killed Off for Real. 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 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.
- Akura-Ou from Kamisama Kiss. One minute he is playful, happy and silly... the next minute he will brutally kill dozens of people for the most trivial of reasons.
- Some fans of the Japanese version of Mewtwo from Pokemon The First Movie have likened him to a scared, confused and angry child, placing him in types B and C of the trope. His motives amount to a psychic powered temper-tantrum (albeit one that is not entirely unjustified) as a result of his mistreatment and some of his dialog is childish in some aspects, saying "Don't tell me what to do!" when Ash and co. confront him on taking their Pokémon. The English dub averts this, glossing over most, if not all, of Mewtwo's childish mannerisms from the Japanese version.
- Akito in Fruits Basket. 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. This is because 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 Big Bad.
- Arguably, Ren Sohma aka the aforementioned abusive mother of Akito. Not only is her ultimate reason to abuse the Hell outta her daughter ultimately very bratty ( being jealous because Akira, her late husband and Akito's father, loved the idea of being a dad), but at some point she tries to kill Akito... over a box that belonged to the dead Akira, simply because she believes everything Akira owned was hers..
- The "Vampire" Clair Leonelli from Heat Guy J is a Mad Bomber 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 Freudian Excuse, though, and his childishness is designed to make him seem fragile and sympathetic as much as it's used to make him frightening.
- Dilandau Albatou of Escaflowne 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 understandable to entirely petty. While Clair above shaded into both Type B and Type C, Dilandau is squarely in B territory.
- Gozaburo Seto of My Bride Is a Mermaid. 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 calls him out on it in the second episode ("I can't respect a father who won't even act like a man!").
- In the Day of the Barney Trilogy, Thorton Marshall is this. Adolf Hitler is also implied to be one, given that he was the only person who Barney corrupted that was not a child.
- In the Pony POV Series, the Dark World version of Fluttercruel more than qualifies as a Type E. Despite being over a thousand years old by this point, she's still mentally a foal who, as Rarity puts it, no one ever explained the difference between a hug and a handgun to — she's a sociopath who gets her thrills torturing and killing things, and throws tantrums when Discord won't let her. This is the result as being raised by Discord, which resulted in her belief that she was showing love to her father by torturing ponies and that she was showing her mother love by torturing her. And this is all before she goes off the deep end.
- Agent Diamond from Akatsuki Kitten Phoenix Corporation Overhaul. It's not quite clear if she's type C, D, or E. She is stated to be quite intelligent despite less than normal comments, and has proven herself to be extremely powerful. She small, pretty, and has a relatively unassuming appearance and demeanor, which leads her instances of extreme violence, complete with creepy laughter to be even more disarming. And said laughter, as well as her background, show that her values aren't exactly the same as most peoples, particularly as she works directly for the author.
- In the My Little Pony: Friendship Is Magic fanfic Cupcakes, Pinkie Pienote is a Psychopathic MareFilly who loves inviting her friends to 'parties' which start with silly jokes and end with their hideous and torturous deaths.
- Vanitas from The Shrouded Path is a mixture of Type B and C. Ultimately, he just wants to be loved by his surrogate parents. He's willing to go to extreme measures to obtain this.
- Female version in Hivefled's Condesce, who along with her partner the Grand Highblood has murdered two and a half thousand teenagers for kicks and horrifically tortured her own son while cooing and cuddling him like he's a puppy.
- Rosario Vampire: Brightest Darkness:
- The original Jovian and Jacqueline Kikion who served Hokuto are a mix of Types C and D. They're both incredibly powerful and nearly unstoppable Hot Witches... and they're also completely Ax-Crazy Psycho Lesbians whose idea of "playing" involves such things as Cold-Blooded Torture, rape, and overall committing wanton mass murder and destruction to the extent that they leveled at least two entire cities to the ground for laughs; to them, life is a game, and killing people is their favorite pastime. To drive the point home, in Act III chapter 42, Jovian even cheers "Yay, I love killing!" in a manner reminiscent of a five-year-old with a cool new toy, and in Act IV chapter 25, when Gin saves Mrs. Aono's life after Jacqueline blows up Tsukune's house just to torment Tsukune, Jacqueline whines that Mrs. Aono should have died in the explosion and that Gin "didn't play fair."
- Falla Cii, before she was killed and replaced with a Good Counterpart from an Alternate Timeline. Her reaction upon discovering that her parents had chosen her sister Luna to succeed them as rulers of the chronofly kingdom was to throw a childish fit and whine about how she deserves to rule more than Luna, before ultimately picking a fight with Luna and destroying said kingdom, along with the entirety of the chronofly species except for herself and Luna, in a fit of rage.
- In Sonic the Hedgehog fanfic Prison Island Break, beneath his mask of a cruel psychopath, Shadow is this. He has almost zero self-control and is almost pitiable in his subconscious desire for somebody who can keep him under control.
- Sonic X: Dark Chaos features Beelzebub, the Lord of Flies. A death metal druggie and Mad Scientist, he's also a sadistic pedophile who gets off on Cold-Blooded Torture. After capturing them, he ends up raping Chris and almost-raping Cosmo simply because he wanted to feel how "tight" they were.
- Veress, the Big Bad of Blood and Spirit, the first entry in the Bound Destinies Trilogy. The entire reason for her Heel-Face Turn is incredibly petty and childish: she was passed over as leader of the Sheikah in favor of Sheik. Essentially, the entire plotline was kicked off because Veress is an immature brat who didn't get what she wanted.
Film - Animated
- Scar from The Lion King. Best exemplified when he says "I'm king, I can do whatever I want!"
- Kadaj and his group from Final Fantasy VII: Advent Children, a group of superpowered teens created from Sephiroth's refusing-to-be-dead essence. Kadaj, a mix of B and C, can go from vicious and sadistic to heartbreakingly childlike and back again in the span of around fifteen minutes. His older 'brother' Loz also qualifies as type A, being less psychotic, but more childlike. Probably Yazoo as well, as type C. He doesn't get much screentime, but just watch him laughing in childish excitement in the extended version as he steers his motorcycle off an exploding bridge to attack an airborne helicopter.
- Syndrome in The Incredibles balances a genius-level talent for inventing technology with an incredibly childish personality; he's immature, excitable, petulant, irresponsible, prone to mood swings, obsessed with gadgets and 'toys', and spiteful. His entire motivation also stems from an admittedly wounding and hurtful but still relatively minor slight he suffered when he was a child, which he refuses to move on from.
- Prince Charming in Shrek the Third.
- The Bowler Hat Guy from Meet the Robinsons.
- Prince John from Robin Hood. A petulant, temperamental, selfish, impulsive crybaby who sucks his thumb and cries for his mommy. The real Prince John (later King John) is often depicted this way in other works, but whether he truly was is impossible to say.
- Gaston's role in Beauty and the Beast pretty much consists of him throwing a very violent temper tantrum when he doesn't get what he wants.
Film - Live Action
- Leatherface from The Texas Chainsaw Massacre is a mentally-retarded tool of his family, who uses him to gather meat for their restaurant.
- Jason Voorhees, of the Friday the 13th films, is a dimwitted undead creature who kills because he thinks his mother's ghost is commanding him to do it.
- Jacob Goodnight (as played by pro wrestler Glen "Kane" Jacobs) in See No Evil. Like Jason and Leatherface, his madness resulted from childhood trauma.
- Michael Myers is actually an aversion. In the original Halloween (1978) he just kills his sister without any real reason. Dr. Loomis describes him as being "pure evil". It wasn't until the remake that he became this. This was a major criticism since it took away from the looming mystique of the original character.
- Loki in Dogma. Since Angels apparently don't have a conscience and he used to be the Angel of Death, before resigning when he got pissed, there may be a reason to this.
- Norman Bates from 'Psycho has a gangly childishness, due to his mother's isolating and dominating him. It becomes more obvious when Lila Crane snoops through the Bates home and comes across Norman's room.
- The movie Mad Max: Beyond Thunderdome, has the title character facing off against "Blaster" in the eponymous Thunderdome. ("Blaster" is the masked, hulking, none-too-bright bodyguard of Master, one of Bartertown's leaders.) Max outthinks Blaster, knocks off his mask, and is all set to kill him when he discovers that Blaster has Down Syndrome and is essentially a child in a giant's body. Max relents, but the people who hired him to kill Blaster aren't feeling quite so charitable...
- Most of the villains in the Burton / Schumacher Batman series.
- It's almost obligatory to depict The Joker this way, but the 1989 film takes it a step further by showing him as the apparently sane (but still very, very evil) Jack Napier prior to his transformation. In between the vicious murders he committed as Napier and then continues to commit as the clown he becomes, the Joker "punches out" two television sets with a gag boxing glove, blows into a birthday-party noisemaker (possibly the film's single funniest scene), obsessively cuts up photographs to make collages of them, hosts a parade with giant cartoon-character balloons, makes funny sound effects with his mouth, and sends the woman he's stalking a note written in crayon.
- In Batman Returns, the Penguin spends a good deal of screentime wearing only a onesie-like garment stained with his own spittle and slobber. Furthermore, he rides around in a giant toy rubber-duck vehicle and amuses himself with an umbrella (among his collection of genuinely deadly ones) hung with little plastic animals reminiscent of a mobile found in a baby's crib. ("Shit! Picked the cute one!") Actually, the Penguin is more of a Type C - a quite sane and intelligent (though, again, extremely evil) man who simply has not been able to grow up because of his Daddy Issues.
- While vandalizing - and ultimately blowing up - a department store owned by the man who attempted to murder her, Catwoman takes some time out from her mischief to girlishly "skip rope" with her trademark bullwhip.
- Near the climax of Batman Forever, the Riddler and Two-Face play a game of Battleship that uses real torpedoes - and the Batboat (piloted by Robin) is their target.
- The DVD commentary for Thir13en Ghosts provides backstory for the Black Zodiac. This trope is represented by The Dire Mother and The Great Child, the Mother being a little person in a travelling circus and the Child being the result of rape by the circus' Tall Man. He was extremely spoiled by his mother and appeared as a fat, hulking brute of a man wearing diapers and a bib and carrying the axe with which he had killed his mother's murderers.
- Kim Jong-un as portrayed in The Interview. He is so volatile and insecure that he flies off the handle and tries to nuke the whole world just to demonstrate his worth as a leader.
- Tokka and Rahzar from the second Teenage Mutant Ninja Turtles film. As David Warner's character puts it:
They're not stupid. They're infants. (Beat) Okay, they're stupid infants.
- The Merrye siblings in Spider Baby or, the Maddest Story Ever Told, who have a condition that causes them to revert intellectually until they have childlike minds in full-grown bodies. This enables them to do things like kill deliverymen as part of their games, and demonstrates how excellent it is that humans can be taught morality before they're big enough to do real damage.
- Repo! The Genetic Opera's Luigi Largo is a rather brutal murderer, and most of the time seems like a functional adult, but a stern look from his father or a sharp word from Mag can turn him into a contrite toddler. He also throws temper tantrums that would be hilarious if he didn't have a knife in his hand while he had them. At the end of the film, after Rotti's death, he breaks down sobbing in the middle of menacing a crowd of people.
- Zigesfeld in If Looks Could Kill displays multiple signs of mental retardation, including a childlike dependence on the film's female villain. When she strokes his mechanical hand in one scene to calm him down, he grins like a little boy.
- The towering 'trolley boy' Michael "Lurch" Armstrong in Hot Fuzz. According to Danny, he's a product of incest and has the mind of a child. When the members of the NWA are booked at the end of the movie, he's bawling like an infant
- The 1963 film Cleopatra portrayed Octavian (the future Augustus Caesar) as one of these. The historical community was Not Amused.
- The main villain of The House by the Cemetery is hinted to be one, as he is constantly crying like a little child. The film even closes by a quote by
Henry James Lucio Fulci that says "No one will ever know whether the children are monsters or the monsters are children".
- Don't!, one of the joke movie trailers in Grindhouse, Nick Frost has a cameo as a cannibalistic man-baby locked in the basement of the house. Part of the central joke of the trailer is that everything happens too quickly to get a sense of what kind of horror movie it is, so it's hard to say much more about his character.
- Stuntman Mike in Death Proof, one of the actual films featured in Grindhouse. He puts on a suave act, but at his core he's a vindictive juvenile who gets off on doing cruel things to people. His demeanor in the last act, when he comes across some women who fight back, is that of a kid whose prank has backfired on him.
- Olaf in The Sinful Dwarf is a particularly frightening and extreme example. He plays around with eerie wind-up toys and uses them to lure girls in to be used as sex slaves. Just watching Olaf can be nauseating.
- The eponymous character of The Mask. By the Doctor's analysis, the mask actually makes to surface all the "inner child" from that person, so it fits for all characters ever wearing it.
- In Suicide Kings, one of the No Name Given kidnappers holds a gun to his partner's head, cocks the hammer, and begins to pull the trigger...because his partner changed the channel while he was watching a cartoon and wouldn't change it back. After he leaves, the partner checks the cylinder of his gun and finds that it was fully loaded.
- Near the end of The Last King of Scotland Nicholas is captured by Idi Amin's men trying to flee the country, tortured and confronted by the dictator, leading to this little exchange:
Idi Amin: I am the father of this nation, Nicholas. And you have most... grossly... offended your father.
Nicholas: (battered and bloody) You are a child. That's what makes you so fucking scary.
- The Ghost of Christmas Present from Scrooged is a female example.
- Team America: World Police's depiction of Kim Jong-Il.
- Suzanne Stone of To Die For is an evil woman who seduces a (very dim) teenager to get him to kill her husband, and her intellect level is just barely above his, or above a child.
- Shinzon of Remus from Star Trek: Nemesis. He initially justifies his actions by a desire to free his people, and then by a desire to unify Romulus and Remus, and then by a desire to remove the threat posed by the Federation...but by the end of the movie, it becomes pretty clear that all that he really cares about is proving his superiority to his "father" Captain Picard.
- The various Harry Potter film adaptations portrayal of Bellatrix Lestrange depicts her as having shades of this. For one thing, shortly after murdering Sirius Black, as well as her re-encounter with Harry at the burrow, she taunts Harry about her direct involvement in Sirius Black's death by singing "I killed Sirius Black!" repeatedly in a similar manner to a playground taunt by preschoolers.
- In A Fairly Odd Movie: Grow Up, Timmy Turner!, the Big Bad, Hugh J. Magnate, ultimately turns out to be one once he gains access to Cosmo, Wanda, and Poof's magic. This is foreshadowed by the fact his evil lair is designed more like a playland. He says that this came from the fact his father never let him have a real childhood.
- Sarah from Hocus Pocus.
- Baby Firefly from the Houseof 1000 Corpses films. She cuts the heads off of dolls and nails them to the wall, has a childish high pitched voice and giggle, and recited the Rabbit Hutch rhyme while murdering a woman that she put in a rabbit suit.
- William "Wild Bill" Wharton, from The Green Mile, displays shades of type C of this trope, at least in the film. Despite being on death row, his antics seem more childish and goofy than anything else, sometimes being played for laughs, until it's revealed he raped and murdered two little girls while working as a farmhand, a crime for which John Coffey takes the blame.
- Coffey himself is viewed this way in-universe, at least by the attorney who prosecuted him. When the main character stops by the attorney's house to protest Coffey's innocence, the attorney tells him about a dog he once owned who would bite people and then act sorry afterward, implying that John Coffey is much the same way.
- Butterfinger, the Dumb Muscle of the group of rogue CIA agents in Hudson Hawk. At one point, when the other agents are complaining about how long Hawk is taking with his Love Interest, Butterfinger asks, "You want me to rape 'em?" There's a long, uncomfortable silence, and then one of the other agents hands Butterfinger a book to distract him. It's Dr. Seuss' Green Eggs and Ham, which Butterfinger seems to struggle with.
- Charlie Chaplin's The Great Dictator's depiction of Hitler is of this trope, as evidenced by how he interacted with his "globe."
- Agent Lynch from The A-Team acts like a 16-year-old with daddy's credit card and car keys. He leers at his assistant, constantly brags about how much cooler his job is than his opposite number's, and displays childlike glee at all the cool toys he gets and stuff he gets to do.
- Chronicle: What Andrew Detmer becomes by the end.
- The movie Game Over has one, in the form of a supercomputer named Drexel, which threatens to destroy the world unless someone plays video games with it. To add to the effect, Drexel is voiced by a child actor.
- Pee-wee Herman edges close to this trope in some parts of Pee-wee's Big Adventure, especially when he is shown becoming increasingly obsessed over the theft of his bicycle.
- Skank in the film version of The Crow. He's a rapist, a murderer, and a car thief. He also frequently acts like a brain-dead hillbilly and is treated as a Butt Monkey mascot for the rest of the gang, and he cries like a little boy whenever he's in danger. He eventually becomes so cowardly and pathetic that he essentially turns into an Ineffectual Sympathetic Villain, and the film has to flash back briefly to Skank's rape of Eric Draven's girlfriend in order to justify Eric's killing of him.
- In Naked Gun 33 1/3: The Final Insult we have Tanya Peters, the moll in a band of mercenary terrorists. She actively participates in the gang's crimes, and seems to know exactly what she's doing (and also that the gang's ultimate goal is to blow up a building full of hundreds of innocent people)...and then there are other times when she seems completely oblivious to the fact that she's surrounded by ruthless criminals - or that she is one herself - and comes across as more of a Spoiled Sweet Brainless Beauty. Eventually, she has a Heel Realization and rats out her accomplices. This was all Played for Laughs.
- The backwoods rapists in Deliverance might qualify as an example of Type E. They're so deformed due to inbreeding that it's easy to imagine they're mentally retarded as well, and don't understand that rape is wrong or cruel. After one of them forces one of the campers to strip down to his underpants (or "pannies", as the hick creepily refers to them) and then mounts the victim, he pretends he's riding on the back of a pig, playing rather than committing a horrible crime. This would lend an Alternate Character Interpretation to the hicks when they turn even more violent after the campers kill the rapist in self-defense: in their simple minds, they're acting out of righteous anger (or perhaps even self-defense themselves) that these city-slickers would murder one of their own for no reason when they were just trying to have some fun.
- Amon Goeth in Schindlers List. He has tantrums like a child, does things on a whim, and likes to break his toys. Unfortunately, in this case, his toys are human beings being starved and worked to death, who he kills on the merest whim (e.g., he wants to kill someone). Accent on the "merest" part.
Goeth's Mistress: "Amon, you're such a damn fucking child!"
- Johnny Truelove of Alpha Dog is an impulsive, shortsighted, criminally dumb wannabe gangster trying to project a "tough guy" image. He kidnaps Zach on a whim, threatens people wherever he goes, and doesn't realize how many witnesses he creates because of his own poor planning. He doesn't even keep tabs on the murder he orders while going out with his girlfriend and having fun, and rejects the option his father offers to release Zach and spend minimal jail time even though he has no other plan himself. He remains elusive for so long only because of blind luck.
- Gary from The Gamers films is not a villain, but he falls into this territory during his Sanity Slippage at GenCon in Hands of Fate. Most geeks can sympathize with the pain of becoming emotionally invested in something Too Good to Last. But is repeatedly physically assaulting the costumed mascot of the series that you blame for your favorite show's cancellation really the behavior of a sane adult? (It's also worth noting that Ninja Dragon Riders, the late, lamented series in question, appears to have been intended for the Shōnen demographic. So for additional Psychopathic Manchild points, Gary's being driven to violence by his emotional overinvestment in a program intended for twelve year olds.)
- Silva from Skyfall has an almost gleeful childlike attitude when it comes to what he does. But it's best exemplified at the end when he realizes M is slowly bleeding to death, he devolves into a whimpering, scared little boy and proceeds to lovingly embrace her while begging her forgiveness.
- In X2: X-Men United, thanks to the brain surgery, Jason Stryker's both very easily manipulated and childishly devoted to his abusive father - to the point that when Magneto catches up with him, all he needs to do in order to change Jason's mind is have Mystique transform into Stryker and give him a new set of orders. For good measure, within his illusions, he usually depicts himself as a child.
- The Emperor in Return of the Jedi acts very giddy when he taunts Luke, trying to get Luke angry. And his torture of Luke is more childish sadism than actual anger.
- In A Brother's Price, Keifer Porter. Emotionally abused all his wives, cruelly tortured and raped one of the younger ones, and used his Brainless Beauty to not be punished for it by the elder sisters. Everyone agrees that he was simple-minded, and childish, though not without some cunning. Turns out there was someone more intelligent than him behind his poisoning his father-in-law.
- In one of the creepiest moments in the entire Agatha Christie canon, when the murderer in "Three Blind Mice" finally reveals themselves to their intended last victim, their voice suddenly devolves to that of a child.
"I said that I'd kill you all when I grew up and I meant it! I've thought of it ever since! I'm grown up now; grownups can do what they like!"
- Merricat in We Have Always Lived in the Castle. She started out as a psychopathic child and is still very childlike though over 20.
- Mr. Teatime of Terry Pratchett's Hogfather is one of the creepier examples.
- From the other extreme of the spectrum, the same book features Banjo, an even more child-like thug, who is clearly mentally handicapped, and comes across as much more innocent. And he and Teatime are friends. Or at least, he does what Teatime tells him to while Teatime treats him with dismissive contempt.
- Another Pratchett example: First Mate Cox in Nation is at one point given a description suggesting this, when his gleeful expression at shooting down a parrot was compared to a little boy proud of wetting himself. On the other hand, at no other point is he shown as anything but fully, rationally aware of what he is.
"First Mate Cox had a choice, every day, and had chosen to be First Mate Cox."
- Doopy and Goshy the clown brothers in The Pilo Family Circus are insane like all the other members of the clown division, but manifest their particular lunacy in remarkably childlike ways which seem quite harmless at first: Doopy has the mental age of about six years old and has a habit of whining like an impatient child, while Goshy communicates only in whistles and beeps and is in love with a potted plant. However, Goshy's apparent incompetence is offset by his appetite for wanton destruction and uncanny bursts of sadistic intelligence, and Doopy will fly into a homicidal rage if his brother is even mildly threatened.
- JJ, the protagonist's vile alter-ego, will gleefully commit murder, vandalism, assault, and any number of crimes for his own childish amusement. However, if anyone responds violently or threateningly, he'll react by bursting into tears and running off.
- The Howlers, an ancient race of genocidal warriors in Animorphs. Jake was essentially expecting them to have the mind of a super-predator, but upon morphing into one, he discovers to his shock that they are actually possessed of a childlike simplicity and engage in genocide because they think that it's just a fun game. Eventually, the Animorphs were able to exploit this by revealing to the howlers that their victims are more than just mindless toys which exist for their amusement, thus "ruining" them.
- The Somnambulist by Johnathan Barnes features a pair of these, called The Prefects.
- The (presumed) Big Bad of The Meq is the Fleur-Du-Mal, who, like the rest of the eponymous race of immortals, is Really 700 Years Old, but he's also a Psycho for Hire with a bone to pick with the rest of his race. He likes to cut throats, kidnap little girls and turn them into prostitutes, dabble in the occult, manipulate normal people, or Giza as they're called, with his appearance as a twelve-year-old boy, and sadistically torment his own kind. Yeah, he's a Jerk Ass.
- Soon, Ray's sister, Zuriaa was dangerously unstable and became Fleur-de-mal's twin. What a plot twist.
- In the Redwall book Martin The Warrior, the heroes come across a tribe of Chaotic Neutral wild squirrels who live for pleasure and think it would be a really fun game to chase said heroes up a cliff and throw them off! They do end up working for the good guys later on, as they're convinced this would be an even better game. Also, the horribly spoilt Prince Bladd (though his age is unclear, so he may in fact be fairly young). He likes playink mitt fire.
- In Tad Williams' Otherland, the Other is the quasi-sentient operating system of the eponymous network. One of its many bizarre attributes is that, despite being at least twenty years old, it seems to have the personality of an autistic child, and at several points in its "development", the Grail Brotherhood attempted to have it communicate with real children, in order to allow it to develop the capability to interact with people. The Driving Question of why an apparently home-grown AI behaves this way is only resolved when it's realized that the Other is not actually an AI; it's a real human child, stolen at birth and implanted as the "brain" of the network.
- Ronald Niedermann from the Millennium Trilogy. Freakishly strong, near-invincible due to congenital analgesia, and extremely intelligent. He is also irrationally devoted to his unloving father, has probably never physically achieved puberty, and is plagued by bizarre and terrifying hallucinations. Knowledge of which (or not) can come in fairly handy.
- In Codex Alera, this seems to be the eventual demeanor of the Vord queen as she slowly becomes more and more human in her emotions.
- Nightblood from Warbreaker is a lot like this, acting much like an optimistic child eager to please its owner — by killing things.
Nightblood: I did very well today. I killed them all. Aren't you proud of me?
- From Harry Potter: Dolores Umbridge, Bellatrix Lestrange, and arguably, Voldemort himself.
- In Death: A number of the murderers can be considered this. That doesn't make them any less dangerous, though.
- The Phantom of the Opera: Type B and C. In the original book the Persian and Erik himself lampshade Erik's attitude as childish, and despite his multiple talents, he is not interested in sex but to have a beautiful wife and a life like any other guy. It's only when he actually triumphs that he realizes how impractical those dreams are. Also the Persian treats him as a spoiled child when he interrogates Erik about Raoul and Christine destinies.
- Mirror, Mirror: The Borgia siblings are both C and E. Though they're less Ax-Crazy than unable to understand basic concepts like "breaking promises, ordering assassinations and sleeping with family are bad, bad things".
- A Song of Ice and Fire:
- Lysa Arryn throws tantrums like a spoiled child when things don't go her way and ignores her responsibilities as Lady of the Eyrie in hopes that they would go away. And when her new husband Littlefinger forcefully kisses her niece Sansa, she tried to murder the latter because she believed they tried to steal what belongs to her.
- Cersei Lannister covers her inner woman-child with a huge layer of The Vamp (and all the Manipulative Bitchiness that requires) with aspects of Mama Bear in adulthood. But, her primary motivation for much of what she does is what it's basically been since she was very young... a massive tantrum that she can't get the cool toys like the boys do (or, more specifically, like Jaime does). And, Daddy won't look at me like he does him! (So, I'll be better than Daddy!) It's not very pleasant when it combines with a streak vicious enough to advocate torture, murder and, occasionally, outright acting like her brother's (and cousin's) Lady Macbeth when she isn't being her children's My Beloved Smother, so any sympathy you might have for her points about the inherant unfairness in the Stay in the Kitchen attitude of most of Westeros gallops out the window thanks to her general toxicity.
- It's still up in the air about the inner workings of Petyr "Littlefinger" Baelish. Whilst the execution of his plans are certainly mature, he is solely motivated by his by his childhood affection for Catelyn Stark. The entirety of his plan so far can easily be viewed as a massive temper tantrum simply because he couldn't have her for himself, leaving almost the entirety of Westeros devastated by war and with winter just around the corner too...
- Ramsay Bolton is still the little boy who pulls the wings off flies, roasts living grasshoppers, drowns kittens and beats nerds for lunch money whenever he feels like it inside. Just all grown up enough to add raping and flaying people to the list of things he enjoys doing.
- Vlad Tepes in Count and Countess.
- Given Palpatine's views in Darth Plagueis, its strongly implied that Palpatine grew up to become a high functioning version of a Psychopathic Manchild.
- The Colorman in Christopher Moore's Sacre Bleu who always shrugs off his murders with "Sorry. Accident. Couldn't be helped." and his molesting the female help with "Penis".
- G. K. Chesterton's Manalive features Innocent Smith, an apparently mad Blithe Spirit who gleefully takes charge of a small community and changes everyone's lives for the better... before pointing a gun at someone and being arrested as a serial killer. It's gradually revealed that he has never, in fact, killed anyone.
- The Tome of Bill has two examples.
- First is Jeff. He acts incredibly childish and has exaggerated opinion of himself. He throws a fit whenever he doesn't get his way and is generally an all-around douchebag.
- Second is Gansetseng. She's actually over three hundred years old, but she was turned when she was just twelve and hasn't physically aged since, and has barely aged emotionally thanks to her "father" (actually her some odd great-grandfather) treating her like a child for all her life.
- According to The Disaster Artist, Tommy Wiseau is pretty much this as he acts very childish throughout the book, even when he's trying to manipulate someone.
- John Dies at the End has an interesting example in that the Psychopathic Manchild is Korrok, a gigantic amorphous Eldritch Abomination with the mental maturity of a 13 year-old who just discovered his first batch of cuss words. People under his control tend to do things like blurt out offensive comments and do strange and depraved acts like stripping naked in the middle of the street and packing snow onto their crotch or pissing on the hood of the protagonist's car, and his idea of tormenting the protagonist is to turn on his car radio and replace all the song lyrics with racist diatribes. When Dave and John finally meet him, Dave notices that his voice sounds like a toddler's.
- Lennie in Of Mice and Men could be considered this, aside from the fact that he is not psychopathic. Unless you count the fact that he outright murdered Curley's wife because she was screaming. And she was only screaming because he was hurting her, and wouldn't let go of her.
- Reach, the King of the Cranes, from the Skyscraper Throne series is a particularly extreme example. On the surface a nigh-unkillable, several hundred year old god, underneath he's a Fetus Terrible, struggling to be born.
Live Action TV
- The main character of the Thomas Fersen song and music video "Hyacinth".
- Maxwell Edison qualifies as Type C on The Beatles song Maxwell's Silver Hammer
- George Steele, during his heel run. He then became a sympathetic baby face, all without really changing his in-ring style.
- The gimmick of Abyss in TNA is this trope. When he's a face, the sympathy is milked for all it's worth.
- Poor, poor AJ Lee. The Ambiguously Brown cutie was never the same after Daniel Bryan publicly dumped her (although that blow to the skull she took from The Big Show when he nearly broke her neck during a title match with Bryan might also have been a factor), and she quickly descended into a morass of self-pity and highly erratic behavior that eventually turned dangerous. Among her frightening deeds are making sexual advances toward every man she comes across, wearing a red leather mask similar to Kane's, putting both Bryan and CM Punk through a table for no apparent reason, and...skipping around girlishly in short shorts and a bikini top, although her skipping around during a tag match seemed so out there that even Kane told her that she was too crazy even by his standards.
- The Great Khali is this by default (Type A) during his heel runs. In-universe, he's a gigantic, physically and mentally stunted Indian immigrant who usually just wants to kiss girls and dance to Bollywood musical scores, but unfortunately is just so stupid that it's relatively easy for his much more evil "friends" to warp his mind and turn his phenomenal physical strength toward malevolent purposes. The last of these slavemasters was Jinder Mahal, who not only mentally manipulated Khali but idiotically tried to physically bully him as well, leading to the Crowning Moment of Awesome of Khali finally getting thoroughly sick of Mahal's bossiness and brain-chopping him into submission.
Public Domain Characters
- Most depictions of Frankenstein's Monster follow this trope. (Although not the original version.)
- In Mel Brooks' Young Frankenstein, on the other hand, he's a standard-issue Manchild (at least until the end, where he... ah... stops being anything of the sort). On the other hand, he does come across as being smarter than some of the other characters....
- Not exactly setting a high bar, there.
- The Minotaur is sometimes presented this way, especially in Jim Henson's The Storyteller.
- In Dracula, Mina Murray draws upon the new science of Criminology to profile Count Dracula and describes him of being of the "typical" criminal mind- childish, in thought and behaviour.
- Satan occasionally gets this portrayal, typically when interpreted as God's rebellious (and possibly abused) creation who desperately wants the Heavenly Father's attention. This has become especially common recently, and can easily integrate with any moral alignment (or lack thereof).
- Apply this trope to a species, add a healthy dose of More Dakka and Clap Your Hands If You Believe, let (rule of) cool, and you've got the Orks of Warhammer 40,000. They think that they should do "wot's fun." It's just the rest of the galaxy's bad luck that to the Orks, "fun" means "NEEDS MORE DAKKA! Dat's 'ow ya killz fings!" They're like big, green, comic relief howlers.
- Possibly Ogryns as well, given their fierce loyalty. See Gav and Bob for a Tear Jerker example.
- Of all the violent raving madmen in this universe, fandom chose to make Ax-Crazy Blood Knight Kharn the Betrayer this of all people. Read this collection to see the Champion of Khorne (what a fun guy) engage in activities like finger painting with blood, arranging bodies into amusing messages, and jumping into combat from high orbit (the narrator ended up surfing a Khornate Space Marine).
- One of the Iron Warriors short stories has the Slaughterman, who is described specifically as having a child's unthinking cruelty. He doesn't come to a good end.
- Goblins in the Pathfinder setting have this kind of persona. They're such immature, comically inept little guys that they'd count as Ineffectual Sympathetic Villains if not for their rare moments of competence at murdering innocent noncombatants. In fact, each of the goblinoid races in Pathfinder (goblins, hobgoblins and bugbears) are meant to represent a different kind of evil and the little buggers represent childish random malice incarnate.
- One of the most frightening and powerful incarnations of this trope is seen in the Dungeons & Dragons Demon Lord Kostchtchie, who rules a whole layer of the abyss based soley on sheer power and child like rage. It helps that he's secretly a pawn to Iggwilv, but still, most Demon Lords can't rise to the position, let alone hold onto it, without having shades of the Magnificent Bastard.
- The Fair Folk of Exalted are mostly this. They don't mean to be horrible, horrible monsters, but they don't understand how reality works. They hail from the Wyld, where most any being they encounter is simply a figment of either their imagination or another Fae's, so they have difficulty processing the idea that every individual they meet in Creation is an independent and sentient being. Furthermore, in the Wyld, Death Is Cheap. A Fae killed by another Fae can just shape himself back into existence with a thought, so they have trouble understanding why the Creation-born are so uptight about the stabbing.
- Poison in Dracula: A Love Stronger Than Death is a female example, a fully-grown vampire woman who affects an infantile attitude and carries around an identically-dressed doll while wearing babydoll dresses herself, and takes childish delight in the evil that comes with being a vampire.
- The Order of the Stick
- Thog is a half-orc fighter/barbarian with extremely violent tendencies, a sunny disposition, and an Intelligence score that's probably no higher than 5. Thog is probably the only person alive who gets along equally well with Elan and Nale. Elan and Thog bond over the "Manchild" part, and Nale appreciates the "Psychopathic" part.
- Though more intelligent than Thog, Nale himself falls into this trope once he stabs his own brother simply for not wanting to join his group.
- Xykon, the Big Bad, occasionally has some childish tendencies.
- Belkar Bitterleaf has his moments as well.
- Remember how Elan used to be a benign Man Child? Well, his father General Tarquin devolves into an evil version of this once his Villainous Breakdown really starts kicking in and he vows to kill all of Elan's friends (and cut off his hand) just to get him to finally follow his narrative plan.
- Richard from Looking for Group often shows childish tendencies and extremely bratty and whimsical behaviour.
- Tim the ogre would be a textbook psychopathic manchild (he refers to Cale'Anon as "Chicken", ex. "Chicken needs squishy?"), but has been described by one of his associates as being taking one too many maces to the head.
- Tim is certainly a manchild, but he is really not the violent psychopathic sort.
- Sluggy Freelance:
- Reakk: Even though he's a demon who eats people's souls, it's hard not to like the dimwitted little guy.
- Oasis, with her underdeveloped personality and sadistic fondness of killing. Bun-bun described her as a "demented toddler", and while she's theoretically opposed to killing innocents, once she eliminates someone from that category, she's willing to do things such as cut their ribs out one at a time out of curiosity while they're still alive.
- Agent Gnaaaw, a young woman possessed by a brutish demon, is childishly confused about the distinction between liking someone as a person and enjoying eating them.
- Kharla'ggen of Drowtales is clearly insane and enjoys turning people into living dolls unable to move, but it's implied she's not actually that bad a person under her insanity. Being under the thumb of a Psycho for Hire who used her as a figurehead leader didn't help her at all.
- In 8-Bit Theater, Black Mage is a rare example of a "heroic" Type C, in that he is intelligent and relatively well-put-together, but takes a psychotic, child-like glee from hurting close friends and innocent people for little reason more than the amusement it causes him. His tantrums tend to devolve rather quickly into childish whining as well.
- Fighter is a Type A, who generally enjoys beating the living shit out of people, but is quite friendly and rather... slow.
- Ethan from Ctrl+Alt+Del, who is almost completely bereft of maturity and/or responsibility, even from his own actions. He's Family Guys Peter Griffin, except he's a gamer. Yup.
- Lawler of White Noise could be considered this. He's a skilled, ruthless, cheerfully sadistic operative who's obviously quite a few bananas short of a bunch. Yet he has a child-like unquestioning devotion to his boss, and spends his spare time having fun by drawing all over his hands. Aww.
- Spot of Get Medieval has a childlike enthusiasm for fire and explosions and pure hate for those who try to stop him from making either.
- Jared of Jared, despite being very intelligent and a Badass, is childishly selfish and obsessive.
- Butch of Chopping Block can be this, though the degree to which it applies varies wildly from strip to strip. In one case, his mutilation of corpses was compared to a child playing with a cardboard box.
- Slick, the devil and God (!) show such tendencies in Sinfest.
- Homestuck: Lord English, despite being the untouchable master of Weird Time Shit, is still the same surly Jerkass he was when he was young. Explained in-universe as the result of him putting a hit out on the dream self of Calliope, his sister/good personality, instead of doing a Split Personality Takeover as is normal for their species.
- Quant from Tower of God is a Ranker of the Tower, a position commanding great respect and implying a terrifying amount of power, which he does possess. His greatest weakness is his incredible immaturity, which not only let him self get lead on twice by the examinees he had to train and test, but also caused 197 people to die because he didn't give a shit about concocting a complicated preliminary exam and just settled with a 30 minute death match.
- Schlock of Schlock Mercenary manages to combine this with Sergeant Rock to make for one dangerous blob of ambulatory goo. He's childish, violent, loves Stuff Blowing Up, can and will eat anything he can fit in his mouth, (including people) and the idea of having his hand-held rotary cannon effectively turned into a personal artillery field piece rigged to fire grenade rounds gives him a gleeful expression like a kid on Christmas. Oh, and for a brief period he was Dual Wielding sawed off starship cannons. He's by no means stupid, proving on several occasions to be a cunning tactician and combat leader, but his Blood Knight tendencies and immaturity pretty much guarantees he'll never be promoted above sergeant. And so long as he gets let off his leash to indulge in a bit of ultra-violence he's probably ok with that.
- The titular Axe Cop has a sort of meta-justification in that he's actually written by a small child.
- Agathoth from Cloudscratcher is described like so.
- SHIKI from Tsukihime started off as a mischievous yet unstable kid...then his brutal awakening of his demon blood while simultaneously the Big Bad was taking him over from the soul outwards, impaling his Only Friend and being confined cracked his mentality to become this. Now as an adult, he's extremely powerful, but now he's prone to violent temper tantrums, self-centered, aggressively possessive and just plain creepy.
- Ilyasviel von Einzbern from Fate/stay night whose child-like attitude is slightly justified by the fact that she was orphaned at a young age and never received anything even resembling a traditional upbringing. She's pretty, cheerful, carefree and has an attachment towards Shirou...but after being abandoned by her father and being raised as a Tykebomb Artificial Human with no concept of morality, she will toy with Shirou while pleasantly torturing him.
- Ren from The Ren & Stimpy Show is the clearest example of this trope, behaving like an Ax-Crazy psycho, but behaving childish sometimes.
- If Master Shake from Aqua Teen Hunger Force isn't the definitive example then nobody is.
- Peter Griffin from Family Guy is essentially, Archie Bunker with half the IQ points. He is a bumbling Al Bundy type, who more often than not causes most of the conflicts in the show due to his selfishness or idiocy.
- Glenn Quagmire, Carter Pewterschmidt and even Cleveland have become psychopathically childish adults in recent seasons.
- Also Stan and Roger from American Dad!. To be honest, nearly every adult on Seth MacFarlane shows shows signs of this.
- Futurama's Bender, the alcoholic, amoral gambler who deals porn and has no qualms with selling children as dog food occasionally becomes incredibly childish, most notably in the Mom-centric episodes.
"Mom! Mom! Look at me, Bender! Hey-ho, I want attention!"
- Though he is only four. At first.
- Zapp Brannigan also counts. He's very cowardly, dim-witted, immature, narcissistic, and perverted. He's also a high-ranking officer in the Earth's military, with disastrous results.
- Toyman of the DCAU, recreated as a childish madman who wears a doll head with a creepy smile.
- The comic book sequel of Batman: Mask of the Phantasm implied that The Joker himself was a psychopathic manchild after his transformation. Despite Phantasm's hatred for the Joker, when he's finally caught at the climax, there's a moments hesitation as Phantams realizes Joker isn't the same ruthless mob hitman from years ago, but just a grinning lunatic, no longer capable of remorse, and motivated only by a desire for personal stimulation through murder.
- Batman: The Animated Series has a rather Tear Jerker Deconstruction in "Baby-Doll"; The eponymous supervillainess is a 30 year old actress with a medical condition that causes her to look about five, despite having the emotional and intellectual maturity of her actual age. Because of this, she was never taken seriously beyond her original role in a sitcom and ended up being Driven to Madness, throwing up her Cheerful Child stage persona as a psychological shield against her miserable existence (though it isn't perfect-she slips up and reveals her true, depressive personality on occasion). The plot is driven by her attempt to recreate the show's setting in an attempt to return to the one happy part of her life. Her emotional immaturity is a mask to help her avoid her problems with adulthood, as revealed when she crosses the Despair Event Horizon.
- The eponymous character of Invader Zim can edge toward this. His interactions with his leaders, especially.
Zim: My Tallest! My Tallest! My Tallest! My Tallest! My Tallest! It's me! Look at me! My Tallest? My Tallest!
Zim: But I must get my equipment or... I won't... get it.
- Squidward from SpongeBob SquarePants. While he's generally reserved and keeps to himself, a lot of the time he's Not So Above It All and will join in on Spongebob and Patrick's antics, usually taking it too far. Probably the best example is "Snowball Effect", where he at first stays away from snowball fights and discourages them. After trying to manipulate them into fighting again, he starts violently throwing snowballs, causing Spongebob and Patrick to do the mature thing and leave the fight while he's reduced to a psychotic wreck.
- Plankton also may count. It was in the early seasons an evil enemy, especially as he is seen in the film, but at least as seen in the episode "FUN", seems to have pretty a childish side with SpongeBob when he befriends him. And it is assumed that Plankton is almost as old as it is Mr. Krabs.
- And SpongeBob himself in later seasons.
- Patrick could also count, given how often his stupidity puts himself and those around him in danger.
- Grimlock from Transformers Generation 1 is a Psychopathic Mech-Proto who regularly tries to defeat Optimus Prime for leadership of the Autobots, destroys Decepticons with pleasure and rules his faction of Dinobots with an iron tail... in his down time, he enjoys fishing with said faction, hearing stories about the Good Ole Days from Kup (in the middle of battles) and giving human children and annoying, rhyming Autobots piggy-back rides. He also has his own brand of Hulk Speak.
- Speaking of rhyming Autobots, Wheelie might actually fall into this catagory. He fights about as well as any other Autobot and has taken down robots three times his size, but generally speaks in sing-song rhymes and hangs out with a 12-year-old human boy.
- Galvatron in Season 3 definitely fits this trope, from treating potential mass murder as 'sport' and 'hunting season' for Autobots he acts like a child whenever he loses with the Decepticons taking the brunt of his tantrums. They eventually get sick of it and tell his loyal lieutenant Cyclonus to do something about his insanity.
- The Warden from Superjail puts the Manchild in Psychopathic Manchild. He acts his shoe size and is barely sane enough to even keep his emotions together. For example, in the pilot as the Warden sings and pets a dead rabbit, he rips its skin off in a moment of unprovoked aggression, then promptly puts the bloody skin on his head and orders Jared to get bunny suits for the inmates.
- The X-Men animated series' rendition of Kevin McTaggert aka Proteus. The cartoon took the character and made him a teenaged mutant with the mind of a young child after being locked away from the world by his mother Moira, due to said powers. He possesses people and mindrapes them while doing so, has minor reality warping power (which work like a charm on none other than Wolverine and reduce him to a borderline blubbering wreck for a while), and does all kinds of terrible things... because he desperately wants to see the father who left the family shortly after his powers manifested. While this is a far cry from the horror version of the character in the comics, it's a Justified Trope since this particular X-Men cartoon was an animated series geared towards kids and young teens in The Nineties; Proteus wouldn't have fitted in the cast, had his portrayal not toned down.
- The Batman's version of the Cluemaster. He was a former game show contestant and he believes he lost because his opponent cheated. He has spent 30 years doing nothing but plot his revenge. In his mothers basement no less.
- Brak progressed from a supervillain in Space Ghost to being an annoying loudmouth with a childlike attitude in Space Ghost Coast to Coast, Cartoon Planet, and The Brak Show. It is said that he suffered brain damage after Space Ghost.
- Quackerjack from Darkwing Duck, going along with his "power" of making deadly toys.
- Cheryl from Archer, Combines the D and E types.
- Archer himself might qualify, being somewhere between C and E. (No, not D.) He views killing people as play and is a whining self-centered brat whose world revolves around his mother.
Commander Kellogg: Archer broke both of Wu's arms while shouting "woo!"
Archer: Happy coincidence!
- The Legend of Korra:
- Tarrlok has shades of this in episode 8. He has a lot of power in Republic City but comes off as a spoiled brat who will do anything to get what he wants and won't listen when others try to reason with him. However, it's much more complicated
- Amon/Noatak is ultimately shown to be a this in the finale. He comes across as a naive man who just wanted the good life with his younger brother (who happened to be the aforementioned Tarrlok) that their abusive childhood at the hands of their father, Yakone, denied them.
- Discord from My Little Pony: Friendship Is Magic is an omnipotent Reality Warper and a Magnificent Bastard, but he's basically an all-powerful Trickster God who views the entire world as his own personal play thing. This includes the ponies, who he gleefully Mind Rapes, breaks, and drives insane. He's well aware of how evil his actions are, but doesn't care so long as he's having fun. He also pretty much Rage Quit when Fluttershy actually won his mind games, brainwashing her via brute force and leaving in a huff.
- Baron Vain from The Modifyers, the Big Bad who gleefully goes "Yay!" when his favorite agent shows up, to ecstatically feeding incompetent henchmen to a gigantic fish while playing opera music.
- Darth Maul shows spades of this in his return in season 4 finale of Star Wars: The Clone Wars. He hides himself from Savage behind boxes and can only be lured out by Mother Talzin's bright, floating energy ball, which he chases after in a way you would expect a small child to. Sure, he gets "better", but the effect is still fairly tragic and quite disturbing.
- Senor Senior Junior is a mild form of this trope. At one point when his father told Kim Possible when rescuing a band from the former's clutches, told her that he'll unveil his new toy: a laser turret. Junior then tells Senior that he told him earlier that the turret was not a toy (implying that Junior attempted to play with it), before Senior explained that he meant the term figuratively.
- South Park:
- Satan is whiny, insecure and fickle. He doesn't even seem to be that much of a bad guy, and on his good day his domain can be quite nice a place. But he easily falls under bad influence and will launch an invasion against Heaven or Earth at the drop of a hat.
- Stan's father Randy Marsh sometimes falls into this category, one such example is from the episode "Night of The Living Homeless" in which he threatens the other townsfolk with a shotgun holding them hostage fearing they could become "one of the homeless" (treated like a zombie plague), he then murders his friend Glen after learning he lost his house, then later acting as if he were still alive.
- Shredder's mutant henchmen Bebop and Rocksteady from the 1987 Teenage Mutant Ninja Turtles cartoon were shown to read comic books, watch cartoons, and play video games in their spare time. In general, they also did tend to act very childish.
- Eddy's brother from Ed, Edd n Eddy. He's an adult and he still likes to beat up kids, especially his brother Eddy.
- Adventure Time: The Ice King has shades of Type B and E, though he's a mostly lighthearted example, mostly harmless despite his habit of kidnapping princesses. Then the story takes a much darker twist when his origins are revealed, and how far he's fallen from the man he once was.
- Lord Hater in Wander over Yonder is immature, short tempered, and obsessed with being THE GREATEST IN ALL THE GALAXY! When Wander challenged him over a trophy, he was more interested in the trophy than the planet he already conquered.
- Word Of God is that Hater was originally developed as a child character for a different project. When added to the WOY cast, he was physically aged up to look like an imposing villain... but kept the exact same personality.
- Snaptrap in Tuff Puppy who constantly makes evil schemes for petty reasons (like blowing up the sun to make popcorn), acts like a immature dick to his henchmen, and constantly argues with his mom.
- Humphrey Dumpler, aka Humpty Dumpty, gets given this treatment in Beware the Batman. Whereas his comics incarnation was an Ineffectual Sympathetic Villain, placed in Arkham Asylum because he was genuinely mentally ill even if he was normally non-violent and inoffensive — he finally snapped because of all the abuse his grandmother gave him, murdered her with an axe, then sewed her together with bootlaces to try and "fix" her — the cartoon Dumpty is a child-like man who is driven by revenge, kidnapping people he blames for the brain damage that left him how he is and trying to blow them up in his first episode, then setting up lethal deathtraps in his second episode.
- Dan Vs.: The titular character is definitely this. He recently argued over sci-fi memorabilia with Chris, and has no job or girlfriend, let alone a wife.
- Chris' wife Elise seems to switch between endearment and irritation with Dan. It's gotten to the point where she sometimes treats him as if he were their kid. In "Dan Vs George Washington" she lets him sleep with them (because he couldn't sleep) and proceeds to tell him a bedtime story, much to her husband's disdain.
Dan "Tell me a story..."
Elise "There was once a little prince who was so very angry-"
Dan "Was his name Dan?"
- In that particular instance, Dan couldn't sleep because he was upset that his plan failed, and he says it in a very childish way, sounding more like a kid with a drawing no one wants to look at than a man on a vengeful rampage.
- Scoutmaster Lumpus in Camp Lazlo. Miss Mucus is a Psychopathic Womanchild.
- Works of fiction targeted towards children tend to make the villain fit this trope (Ironically to make the work more appealing to them).
- Card Carrying Villains usually come off as this.
- Vezon in BIONICLE could be called one of these.
