History PsychopathicManchild / LiveActionTV

** ''Series/KamenRiderDrive'': Tenjuro Banno/Kamen Rider Gold Drive, out of a childish and petty desire to take out his anger treated Heart like a toy he tries to break out of fury, he never wants to accept when things won't go his way, and makes sure to taunt his enemies whenever he's got the advantage.

** ''Series/KamenRiderExAid'': [[PerpetualSmiler Parado]] gets bored extremely easily and will not stand still unless properly entertained. His usual reaction to being ignored by [[UnwittingInstigatorOfDoom Emu]] is pretty much the same as that of a child being ignored by their parents -- if said kid was completely untroubled by murder and capable of causing a pandemic with a snap of their fingers. The playful attitude does not impair his TheChessmaster qualities or alleviate the fact that his preferred game is [[DeadlyGame Kamen Rider Chronicle]], where [[AnyoneCanDie civilians]] fight [[MonsterOfTheWeek Bugsters]] to death. [[spoiler: As it turns out this is largely because he was created as a 6-year-old's ImaginaryFriend.]]

** ''Series/KamenRiderZeroOne'' has [[TheGunslinger Jin]], the sociopathic [[TheDragon head combatant]] of the apocalyptic [[FarEastAsianTerrorists terrorist group]] [=MetsuboJinrai.NET=]. He is essentially a dumber [[Series/KamenRiderExAid Parado]] (mentioned above), only interested in causing mayhem and sometimes even going against his party's best interests to make things more fun for himself. On the other [[DramaticGunCock gun]], that doesn't make him any less capable [[TheBrute fighter]] and probably makes him even scarier because he could do anything just for [[ForTheEvulz funzies]].

*** As Ikki's inner demon, Vice is a personification and exaggeration of everything that his host supressed, making him impulsive, melodramatic and selfish, with no brain to mouth filter and a tennous grasp at morality at best. Worse, he is a BigEater who thinks of humans as if they were a particularly tasty kind of cereal.

** King Joffrey Baratheon is slightly older than [[Literature/ASongOfIceAndFire his book counterpart]] -- a man at 17 by Westerosi standards, old enough to sit on the throne, at least -- but is highly immature due to [[RoyallyScrewedUp his upbringing.]] He constantly engages in petty cruelty and takes sadistic delight in murdering, torturing, and humiliating those beneath him [[StupidEvil even when doing so would be to his detriment]], but behaves childishly towards those who stand up to him, usually resorting to screaming "''I AM THE KING''!" Never more apparent than in "Mhysa", when his grandfather and [[NumberTwo Hand of the King]] Tywin dismisses him to his chambers without his supper for insulting Tywin and Joffrey actually responds with "''I'm not TIRED''!"
** While a tad more sympathetic than her book counterpart, Cersei Lannister is still at heart a very immature person prone to cruel and petty behavior. She never really outgrew being the little girl who had a servant girl severely beaten for stealing a necklace. She has even thrown honest-to-goodness ''tantrums'' like a petulant child when things don't go her way. Lena Headey says that she plays Cersei as if she was a wayward 15-year-old who never had any real parenting.

** Ramsay Bolton is intelligent, cunning, deliberate in his actions, a capable fighter and hunter, and purports himself to be the civilized scion of a Westerosi house but he has his moments of indulging in his sadistic pleasures and urges more than he should. Like, for instance, that episode with the pork sausage...This also pushes him into StupidEvil territory despite aforementioned intelligence.

** While Littlefinger's plans are certainly mature, his main motivations seem to be his childhood affection for Catelyn Stark and his resentment of the limitations of his humble beginnings.

* Moriarty in ''Series/{{Sherlock}}'' is this trope in spades. This is in deep contrast to the Moriarty of the original stories by Sir Arthur Conan Doyle.

** The [[Series/TheTwilightZone2002 2002 revival series]] employs this trope in "It's Still a Good Life", a sequel to the classic series episode "[[Recap/TheTwilightZone1959S3E8ItsAGoodLife It's a Good Life"]], with the grown-up Anthony Fremont. Having been coddled his entire life due to his RealityWarper powers, Anthony has maintained a childish mentality well into adulthood, to the point that his 7-year-old daughter is more mature than him.

** The [[Series/TheTwilightZone1959 1959 original series]] plays this trope for drama in "[[Recap/TheTwilightZoneS3E87APianoIntheHouse A Piano in the House]]". Main character Fitzgerald Fortune, a prime {{Jerkass}} and [[CausticCritic extremely rude theatre critic]], gets his hands on the titular object, a magical player piano which can [[MagicMusic make a person reveal their innermost secrets]] when the right piece of music is placed inside of it. He spends the majority of the episode using the piano like a child with a toy, forcing people to show their true colors at his wife's birthday party and laughing at them as they embarrass themselves. But when Fortune's wife, a victim of the instrument herself, places a copy of "Brahms' Lullaby" in the piano, [[HoistByHisOwnPetard it's Fitzgerald himself]] who ends up affected. He confesses to the gathered crowd that deep down, he's a scared, frightened, lonely little boy who has no idea how to show kindness or love to anyone, and so lashes out at those more talented or compassionate than him with petty cruelty and insults. When the other guests realize just how pathetic Fortune really is, they abandon him, and he throws a full-blown temper tantrum ("IF YOU LEAVE ME, I'M GOING TO BE VERY NAUGHTY!"), destroying the room and screaming.

* The ''Series/WalkerTexasRanger'' episode "Deadly Vision" involved a man who abducts children to play with him, he would claim them as his own and kill anyone who tried to take them from him, and if the children angered him enough he would murder them.

* [[MultiethnicName Marlowe Viccellio]] from ''Series/{{Psych}}''. Apparently a normal woman when we first meet her, she is arrested for stealing blood [[JustLikeRobinHood (it was to save her brother's life)]] and sent to a California women's prison, where she quite abruptly turned into this. Given the nature of the show, this is PlayedForLaughs, with a scene of Marlowe acting cute and flirty with her boyfriend [[StarCrossedLovers (ironically, a police detective)]] when he comes to visit her and then, ''seconds later'', joining the rest of the inmates in a violent attack on the guards when they start a riot during a prison variety show. Later, when she is released from prison, Marlowe proves to be perfectly sane; [[ObfuscatingInsanity her "crazy" shtick had been an act to endear herself to the other inmates]] -- which is more heroic than it sounds, because the detectives needed her to cozy up to Santa Barbara's most notorious female gangster in order to uncover some clues toward solving a gang shooting.

** Lydia Rodarte-Quayle quite immature emotionally, being self-centered, severely lacking in empathy, and extremely paranoid. She covers her ears while overseeing [[spoiler:the murders of Declan and his gang]], and insists on keeping her eyes closed while Todd leads her through the bodies, like a child covering their eyes when a scary scene comes on while they're watching a television show.

** There is also Cy in "[[Recap/CriminalMindsS7E2Proof Proof]]", who, despite being born with brain damage, is unsympathetic. The reason for this is that, unlike the examples above, there is no indication that Cy's mental handicap is the ''cause'' of his behavior; for all his childishness, he is not incapable of knowing right from wrong, and he says that he learned when he was a child that [[KickTheDog kicking his dog]] was fun, and [[ForTheEvulz he kills for the same reason]]. He also has the same misogyny as many other killers, takes trophies of his victims, and plans to avenge perceived wrongs by making his brother watch the tape of Cy mutilating his daughter. By the end of the episode, it's clear that, even without his handicap, he would still be a SerialKiller[[note]]and a particularly sadistic one at that; he rapes and takes away his victims' senses with sulfuric acid to kill them[[/note]].

* "Catching Cold", an episode of ''Series/TheHauntingHourTheSeries'', features one of these in the ending: "Little" Jimmy Jeffries, who went missing thirty years ago after becoming obsessed with catching the "Kreamy Kold" ice cream truck. It turns out that by finally tracking it down, he became [[PoweredByAForsakenChild its fuel source]], as it needs a human soul to travel. After spending thirty years completely alone, stuck in his old Little League uniform, and with nothing but ice cream to eat, he went [[GoMadFromTheIsolation completely insane]] and grew into an enormous adult with the mind of a child. [[spoiler: When main character Marty catches the truck, Jimmy explains all of this while exiting the vehicle, telling Marty that ''his'' soul is now trapped. As Marty cries for help, Jimmy ends up [[MadnessMantra endlessly screaming]] "IT'S ALL YOU CAN EAT!" in a high-pitched, childish voice.]]

*** Kilgrave may act sophisticated, but has a hair-trigger temper and no self-control. He has a tendency to [[DisproportionateRetribution use his powers to hurt those who have annoyed or insulted him]] (from making a news vendor throw scalding hot coffee in his own face, making an annoying gambler [[UseYourHead bash his head against a wooden column]], and ordering two house slaves to rip the skin off each others' faces if he doesn't get back within a certain time), hates not getting his way, and [[NeverMyFault refuses to take responsibility for his actions]]. Towards the end of the season, it is revealed that he gained his powers when he was a child and that may have caused him to have this permanent mindset.

** ''Series/KamenRiderZeroOne'' has [[TheGunslinger Jin]], the sociopathic [[GigglingVillain combatant]] of the apocalyptic [[FarEastAsianTerrorists terrorist group]] [=MetsuboJinrai.NET=]. He is essentially dumber [[Series/KamenRiderExAid Parado]] (mentioned above), only interested in causing mayhem and sometimes even going against his party's best interests to make things more fun for himself. On the other [[DramaticGunCock gun]], that doesn't make him any less capable [[TheBrute fighter]] and probably makes him even scarier because he could do anything just for [[ForTheEvulz funzies]].

* In ''Series/AbsolutelyFabulous'' both Edina and Patsy are [[{{Manchild}} womanchildren]] -- alcoholic, irresponsible, drug-addicted {{Cloudcuckoolander}}s -- to the extent that the relation of Edina and her daughter Saffy can be at best described as inverted parenthood, but Patsy is also unpredictable, full of spite, violent and has a tendency to conniptions, and she is especially toxic towards Saffy.
