Sherlock Holmes's client Alexander Holder in the short story "The Adventure of the Beryl Coronet" admits that since his wife died, he has never denied his son Arthur whatever he wanted. The boy grew up to be an irresponsible gambler. Arthur is thus prime suspect in the titular crime.
Angela Nicely: Tiffany Charmers is often bragging and acting snobby, and always wants her own way, and it’s implied her mother Linda spoils her, for instance, in “Starstruck!”, Linda pays extra so that Tiffany can sit in the front row of a concert, claiming that Tiffany deserves the best.
Not even Brother Bear and Sister Bear from The Berenstain Bears are immune. The Berenstain Bears Get the Gimmies has them wanting literally everything whenever their parents take them to the shopping mall — and if they don't get something, they take this trope to embarrassing levels, throwing themselves on the ground and kicking their legs and screaming their heads off. They learn their lesson by the end of the book, but see another cub with “a bad case of the gimmies” in the checkout line at the store, acting just like they did earlier in the book.
In A Brother's Price, Keifer Porter is at the very least 16 when he becomes plot-relevant, but still qualifies, as his behaviour is entirely described in spoiled-brat terms. He is said to have thrown temper tantrums whenever his wives didn't do what he wanted, or sometimes just out of spite so he would have an excuse for locking himself up in his quarters and cheat on them with a lover he smuggled in through the secret passage. As he's from a noble family, and men have Gender Rarity Value in this setting, he likely grew up as Spoiled Brat.
In Bud, Not Buddy, Bud's foster brother Todd bullies him, easily beats him when they get in a fight, and then cries to his parents that Bud hit him for no reason. His parents are easily fooled by his constant lying, including his fake asthma attacks, and give him whatever he wants, even locking Bud in a backyard shed overnight to make Todd happy.
Captains Courageous has Harvey Cheyne, a thoroughly spoiled brat who gets it worked out of him when he is swept overboard at sea and has to spend much of the summer on a fishing boat as part of the crew.
The Chalet School series is full of examples. Two notable Spoiled Brats are Lavender Leigh (in Lavender Laughs in the Chalet School), who has spent most of her life being spoiled rotten by her ditzy aunt, and Emerence Hope (in Shocks for the Chalet School), whose rich parents let her do whatever she wanted, culminating in her setting fire to the summer house. Most tend to grow out of it, usually with some help from Joey, their peers, and the occasional accident.
In Charlie and the Chocolate Factory, along with the twomovies based on it, with the exception of Charlie Bucket, all the children who got the golden ticket are spoiled.
Veruca Salt is the most glaring example out of all of the four nasty kids, to the point that being told that she can't have something that she wants is an out-and-out Berserk Button. In the book and the first movie, it's explicitly mentioned that she's wearing a mink coat. It's not Fur and Loathing here; it's that mink coats were almost never made for girls at the time (mostly rabbit), no matter how wealthy the family. In the 2005 movie, her father, a billionaire business owner, sets up an assembly floor in one of his factories with the sole intention of getting her that golden ticket. She has her parents wrapped pretty much completely around her finger, bowing to her every demand, but both she and they meet with an awful end when her insatiable greed leads her to try to steal one of the squirrels that Wonka uses to sort nuts for his candy. Veruca's song, "I Want It Now!", from the 1971 adaptation is practically "Spoiled Brat: The Anthem". The stereotypical "pony" line is spoofed in the 2005 movie:
Augustus Gloop is a glutton whose parents just won't stop feeding him.
Mike Teavee is allowed to spend all of his time watching television (or playing violent video games in the 2005 version) and apparently subsists on TV dinners. He doesn't even like chocolate or candy; he only found the golden ticket for the sake of having it.
Violet Beauregard goes unquestioned on any of her decisions by her parents. In the 2005 version, she is a competitive overachiever who's managed to win first place in every competition she's participated in, and is determined to not only get a golden ticket but also to win the special prize at the end of the factory tour and believes that she will, merely for one reason:
Violet: Because I'm a WINNER!
In Diary of a Wimpy Kid, Manny is growing into this due to Parental Favoritism. Greg notes (and complains) that his parents will give Manny slack no matter what, such as finding it cute when he vandalizes the door with drawings and allowing him to use his Catchphrase of "I'm only thwee!" to excuse his behavior, and his mother once drove all the way to preschool to cut the crusts off his sandwiches when he threw a tantrum over it.
Her Thumbleness from Dragon and Slave. Her family owns a plot of lands with slaves to work it, and from time to time she goes with her daddy to select one to be entertained by. Generally it seems to mean being played with like a toy and beat up.
Howard Hughes is portrayed as a grown-up version of this trope in the works of James Ellroy. He is frequently described as whining and pouting when things don't go his way (or even when he's told he'll have to wait for something he wants right now).
In the Elsie Dinsmore series, Elsie's aunt Enna, who is younger than her, is very coddled and spoiled. She actively throws tantrums when she doesn't get her way, bullies Elsie every day, constantly steals Elsie's things even when she's not entitled to them just so she can have them herself, and always has her parents scold anyone who dares call her out on her behavior. In fact, she's so spoiled that she continues to act this way even as an adult, after marrying and having children of her own. It doesn't help that her parents are jackasses who condone her behavior because they themselves hate Elsie and her father, Horace.
Soraya in the Farsala Trilogy. She's fifteen, but we first meet her when she's having a temper tantrum in her room, which involves throwing things at servants. Luckily, she grows out of it.
In Flowers for Algernon, Charlie's younger sister Norma was this growing up due to her mother's Parental Favoritism. She grew out of it in adulthood but still retained a mild degree of neediness.
In John C. Wright's The Golden Transcedence, Atkins complains about having to rely on a "spoiled rich man's son" to rescue humanity. Phaethon is actually not spoiled. Just very, very, very pig-headed.
Dudley Dursley is extremely spoiled, though he gets better after Order of the Phoenix. Harry even wonders what Dudley saw when they were attacked by Dementors, creatures who force their victims to relive their worst memories. Harry, of course, heard the last words his parents said before they were killed, but can only guess what they showed someone spoiled by his parents his whole life. Word of God is that Dudley saw exactly that — they forced him to see just what kind of person he was.
Draco Malfoy is a subversion in a way. Although he gets the best of everything, it's often hinted that it's just another way for his father to show off his influence. Several scenes throughout the book show him getting very snippy when he thinks his son is acting... inelegantly. His parents also expect him to do very well in school (and for all his flaws, it's made clear that he's a very good student), as Lucius tells him in Chamber of Secrets that he's upset with him for not being the top student of the class, even if it's just because a muggleborn is.
In the Horus Heresy short story, The Last Church, Uriah Olathaire recounts how he used to be a "little shit" growing up, going as far as to wish he was treated badly to explain why he became a binge-drinking mercenary before his Heel–Face Turn.
Anthony Fremont from It's a Good Life, which was later adapted into a The Twilight Zoneepisode, has had extremely powerful Reality Warper powers since he was born. Because of his age, he has no understanding of right and wrong, and any adult who attempts to discipline him ends up suffering a horrifying fate. As a result, the whole town does their best to keep him happy.
British statesman Lord Chesterfield wrote in Letters to His Son about a different young nobleman: "They have ruined their own son by what they called and thought loving him. They have made him believe that the world was made for him, not he for the world; and unless he stays abroad a great while, and falls into very good company, he will expect, what he will never find, the attentions and complaisance from others, which he has hitherto been used to from Papa and Mamma." (letter 164)
Monster of the Year: When Lulu Toomaloo was a baby, her parents spoiled her rotten — whatever she wanted, she got (Michael guesses that her parents figured it was better than hearing her scream). She's never grown out of this behavior, and her parents haven't either (in fact, she's the reason Station WERD sponsored the Monster of the Year contest, since she made all sorts of threats about what would happen if they didn't). About the only time they don't give in to her demands is when she threatens to hold her breath until she turns blue if they don't adopt Michael and Kevver immediately (she's nuts about them). When he exasperatedly tells the boys about this, Skip also informs them that he had to call a lawyer and have them explain to Lulu why it wasn't possible for them to do so.
In the original Fortune Lover scenario, Katarina was spoiled growing up, and by the age of fifteen was supposed to be a jealous, scheming elitist bitch that would probably end up murdered or exiled for her behavior despite her high status. However, she hit her head when she was eight and had a total personality change as a result of remembering her past life. As a result, she goes from Spoiled Brat to Spoiled Sweet, a change everyone finds equally parts charming and obnoxious as she creates even more problems with her dimwitted behavior.
Even the "changed" Katarina in the novels has been assumed to be this. When she gets a position to the Ministry of Magic, there were rumors of her being one of these, only getting her position due to her connections. The Ministry's staff is disabused of this belief when she comes up at the onboarding.
Oblomov starts as this — his family doesn't even mind if he skips school regularly. In fact, they push him to do so. Which leads to him not coping with life later.
In The Secret Garden, both Colin and Mary are this, at first. Mary acts like this because she was cared for by servants who were instructed to give her her way in all things so her crying wouldn't disturb her neglectful mother. Colin was neglected by his father and coddled and treated as an invalid by the servants because of his (possibly) crooked back.
Something More Than Night: Ward Home Junior is an adult (not noticeably grown up) version. He has spent his entire life coasting on the vast amount of money allowed him by his oil baron father. He thinks of himself as a bigshot movie mogul, but his studio is an ego project that makes many terrible movies and no profits; it's really just a big playset for a kid who never grew up, with real human action figures.
Robert Arryn is the only living heir to a Great House, with a lot of stillbirths before and since. As such, his mother smothers him to the point that he's still being breastfed at age six, and with the ultimate result that he's a budding Caligula, accustomed to annoying guests being executed for his amusement. That being said, after his mother dies and he is surrounded by more reasonable adults, he starts acting nicer to those around him, so it's likely that his mother's influence was the main issue.
Viserys Targaryen is one who has lost his house's fortune and prestige. Despite that, he still acts like one, treating everyone else like crap. This doesn't go well for him when he is with the Dothraki.
Joffrey Baratheon is a dangerous one.
Camille in Thérèse Raquin was cosseted so much as a child that he's completely intolerable to everyone but his mother. She, of course, thinks he's the best son ever.
In Wen Spencer's Tinker, Windwolf mentions that most elves are this because their parents, if they actually have another child, do so only after the one before is fully grown.
The Veldt: Both Peter and Wendy have become very, very spoiled due to living in a futuristic Smart House and being allowed to do pretty much whatever they want by their parents.
The Wandering Inn: Lyonette is the typical spoiled noble child. Even when Erin saves her from being frozen to death, or even eaten, she thinks it to be natural for her to do it, as she is a noble, thus something special. Furthermore, she thinks it's only obvious that she can reside in Erin's Inn, eat her food, and get her assistance when traveling home. After discovering that Erin expects her to work for getting all these things she thinks are her right, she is scandalized and enraged.
The titular protagonist of Wise Child is derided as this by the local village adults and her own cousins, due to having been raised with more food to eat and better clothes than them. The reality is more complicated, as she acts self-centered and bratty largely to hide her sadness and insecurity over being abandoned by both her parents (her father, Finbar, is a sailor always away at sea; her mother, Maeve, is abusive, neglectful, and only pays attention to her when she wants to use her for ulterior motives). Juniper is the only adult who understands this and shows her love, patience, and compassion as her Parental Substitute, which is vital to Wise Child's Character Development into a more mature and worldly person.
