The Toyota Highlander commercials featuring the little blonde kid. He talks about how his parents used to be lame before they got the "cool" Highlander. The way he brags about it and the way he looks down on the kid whose parents drive an older car really give off the Spoiled Brat vibe.
A series of condom ads highlight a very poorly behaved youngster who is obviously accustomed to getting his own way.
A Fruit Roll Ups Ad has it to where a kid says "Pleasssssssssssssssssssssssssssssssssss" throughout the entire comercial for his mother to get him a snack. So she gets him a snack.
Anime & Manga
At first it appears that Chiko, the main character of The Daughter Of Twenty Faces, plays this type straight to form. Then we find out she has a good reason to put up the act that she does. After this the trope is subverted as she practically tries too hard to contribute and be nice to her new "family".
In Spirited Away, Yubaba thoroughly indulges and overprotects her baby, who is self-centered and cowardly. When he is transformed into a mouse and his mother does not recognize him, he goes with Chihiro, becoming her friend, and on their return, shows his mother that he can stand on his own and demands that she be nice to Chihiro.
Rumiko Takahashi used this character twice, in the form of Shūtarō Mendō, of Urusei Yatsura, and Tatewaki Kunō, of Ranma 1/2. Mendō might border on being a Royal Brat, due to the fact his family is insanely wealthy (among other things, they have their own private army and own a considerable chunk of Japan). Mendō is also a Handsome Lech, but Kunō is more of a Lovable Sex Maniac due to the fact his ideas on dating and romance vary between lechery under a pretty guise and outright madness (attacking a girl and making a date the prize in a Heads I Win, Tails You Lose gambit). He can come off as Handsome Lech or even a Chivalrous Pervert to girls unfamiliar with his ways, but every girl who gets to know him better quickly becomes disgusted with him — even Mariko Konjō, the one girl who fell in love with Kunō, quickly got over him in the original manga version.
Akane can come off as a brat if her numerous temper tantrums are anything to go by. Especially so in the episode where she supposedly "went missing", worrying her entire family and causing them to frantically search the city for her, and it turned out she was just on the roof because she was still in tantrum mode.
And Shutarō's sister is just as much of a brat; she's just less pompous and more sadistic.
Shippo from InuYasha isn't exactly a model of behavior himself.
Xanxus from Katekyo Hitman Reborn!. He was a poor boy whose crazy mother managed to make the Ninth pity them and adopt Xanxus as his own son. The Ninth thought of him as his own son, and gave him love and affection — Xanxus, unfortunately, turned into a violent, ill-tempered Spoiled Brat who wasn't used to things not going his way. His being a Spoiled Brat is especially noticeable when one considers that, although being the Evil Counterpart to Tsuna, he actually had much less abuse and neglect in his past.
Even ten years into the future, as much as he's thought to be less of a douchebag than before, he's still ridiculously spoiled and rotten tempered. Most notably the "beef incident" here, where he beat the crap out of a bunch of underlings because he wanted to eat beef, and it had to be the best quality, and it had to be filleted, and how do they expect him to eat this shit?!
Hibari shows signs of being this, as well. Anything he wants, he gets. Or heads will roll. And the Absurdly Powerful Student Council doesn't exactly discourage his train of thought - they're pretty much his personal servants that help do anything (including some very morally ambiguous things) he wants. And just look at his reaction to when Mukuro beat him in a fight - he becomes obsessed with completely annihilating him, since he absolutely hates the idea of ever losing to someone. The only thing about Hibari, however, is that he really does have the strength and genius to justify his haughty, spoilt, stuffy attitude.
Scarlett O'Hara from Steamboy. She's insufferably spoilt for a 14-year-old, which is the result of having five "mothers" (a.k.a. servants) who go through the "motherly" motions for her. She matures quite a bit during the movie and the ending credits implies she stopped being a spoilt girl and became a haughty but independant woman.
A good fraction of all the plots in Detective Conan have this in grown-up form. They either get murdered or end up being the reason why someone was murdered in the first place.
Sonoko is a milder version. Sure, she's a Spoiled Brat quite often, but she's not outwards malicious and cares genuinely for Ran (therefore, she thinks Shinichi's not good enough for her). And her Long Distance Relationship with Makoto is quite cute.
In Yu-Gi-Oh!, Kaiba accuses Noah of being a Spoiled Brat (in addition to being crazy) and he pretty much is; unlike most members of this trope, Noah is incredibly dangerous, having almost godlike powers and an incredibly ego while in the Virtual World, while still having no more wisdom than the child he resembles.
Subverted in (what else?) Neon Genesis Evangelion. Asuka initially appears to be this... until it's revealed that she's doing it on purpose to alienate others because she's suffering from abandonment issues; there's been no-one around in her life to spoil her.
Garma Zabi is portrayed as this in Gundam: The Origin, an alternate retelling of Mobile Suit Gundam. He whines about Char getting all the glory and pesters his more prominent family members into giving him a combat posting so he can earn some fame for himself... after complaining about looking like the "baby" of the Zabi family. It should be noted, however, that this is an Alternate Character Interpretation that clashes with Garma's canon personality from the original anime.
Bright Noa calls Amuro Ray this when slapping him because his father never punched him... Yeah, it doesn't make much sense but he probably meant the fact that he was never corrected for showing a whiny behaviour.
Prussia is apparently also this, as Word Of God says that the reason he is the wayhe is is because the Pope would let him do whatever he wanted when he was a child.
In Wild Rock, Nava is absolutely spoiled rotten by his dad and uncles, gets into everything and has the attention span of a fruit fly
In Kiki's Delivery Service, Kiki after befriending an elderly lady helps her deliver a fried fish cake for her granddaughter's birthday, something that her granddaughter likes. Making the entire thing the old fashion way and battling through a storm, Kiki arrives and meets the granddaughter who only turned up her nose that her grandmother got her another one of those fish cakes and barely gives a thanks to the soaking wet Kiki. Though there are arguable Pet the Dog moments showing she isn't all that. She actually doesn't protest when her friends compliment Kiki's independence and shown to befriend Kiki by the epilogue.
It is pretty much this trope that drove Keima from The World God Only Knows into the kind of...obsessive gamer he is. He has 6 LCD TVs, 6+ home videogame consoles, 10+ portable PFPs, and a collection of gal games... in his own personal game library. And where does this all come from? Well, the "M funds".
Nishiki from Kamisama Kiss mainly due to the influence of his family retainer and right-hand man. Brat part gets beaten out of him by the end of his story arc.
Of course, Viz magazine's eponymous Spoilt Bastard Timmy Timpson. In every strip he bullies and emotionally abuses his rather weak-willed mother, blaming her for whatever problem he's caused (and what's more she always believes it's truly her fault) and leading her to spend money she doesn't have to cater to her son's every whim. In one old strip he pretended to be sick to get out of school and kept implying that it was his mother's fault. The doctor then tells Timmy's mother that There's nothing wrong with your son that a good smack on the bottom wouldn't cure!. In the annual he runs away from home because his mother put two sugars on his Weetabix when "She knows!" that he only has one and three quarter sugars.
Like the picture above, Veronica wants to get a job like all her friends have, but she's just not motivated enough to actually apply for one. In one comic chapter, everyone is busy with their summer jobs... except Veronica. She has no siblings (that we see, anyway), and her parents are busy running the family corporate empire, so she's pretty much alone and already bored with the empty days of summer vacation. She wished she had something to do, even a job, because this boredom is driving her crazy. Archie eventually comes by and visits, telling her about this one position open at the jewelry shop in the nearby mall. He says this position would be perfect for her, since she wears so much of it. Veronica looks like she's going to accept... then decides not to, because she's so wealthy she doesn't need to work. Apparently, having loads of money means one can never get an actual job, even if it's just to pass the time.
Deconstructed the Kung Fu Panda fanfic series, the Necromancers Of China Saga. Po and Tigress meet their daughter from the future, Fenhong Se. They eventually learn that their future selves spoiled her so much and gave her deverything, but she could not get the one thing she wanted most: to be a greater hero than either her mother or father. Her spoiled nature plays a vital part in the existance of a Bad Future, causing Po and Tigress to realize they must raise her properly when the time comes.
Harry Riddle thanks to his "auntie Bellatrix" spoiling him rotten:
Harry: Can we go to Diagon Alley anytime soon? The letter demands my reply by today, you know, but I already sent it, so don't worry. But Draco's already gotten all of his stuff. Can I get a snake? I want a snake. Or . . . Can I take Nagini?
Voldemort: No, you may not take my familiar.
Princess Vespa in Spaceballs. Her car's license plate even reads "Spoiled Rotten". Case in point: "My industrial strength hairdryer. AND I CAN'T LIVE WITHOUT IT!"
Child star Darla Dimple in Cats Dont Dance is this to insane levels, demanding that she be given everything she wants and be focused on 100% of the time. How she got this way is never addressed, since she doesn't seem to have parents.
Missy Wiener from Welcome To The Dollhouse. She acts innocent and sweet, but in reality she's a Manipulative Bitch who has mommy and daddy wrapped around her finger. Her favorite pastime is baiting Dawn into getting into trouble.
There was Arthur Hoggart's granddaughter in Babe, who upon seeing the beautifully made doll house that her grandfather had spent so much time making began crying, screaming that it wasn't the one she had seen on television.
The meaning behind the title of The House of Yes. The character of Jackie was so spoiled that the word "no" was simply never spoken in their household.
Although Veruca is the most glaring example in the book, the other children (except for Charlie, of course) are spoiled brats themselves. Augustus Gloop is a glutton whose mother just won't stop feeding him, Mike Teavee is allowed to spend all of his time watching television and apparently subsists on TV dinners and Violet Beauregard goes unquestioned on any of her decisions by her parents.
Another male example: Draco Malfoy shows symptoms of this, and his parents don't seem inclined to put any limits on his behavior.
Similarly, Dudley Dursley, although he's tame compared to Draco. Whereas Dudley just likes to beat up Harry (until the seventh book, anyway), Draco actually wants him dead.
Dudley is EXTREMELY spoiled, though he gets better after the fifth book. 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 is a subversion in a way though, as 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.
Especially in the second and fourth movies, where Lucius has no qualms whatsoever about moving people around bodily with his cane.
In The Secret Garden, both Colin and Mary are this, at first. But Mary was ignored by her mother and Colin by his father, and playmates and exposure to garden and the wild cure them.
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.
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.
Robert Arryn in A Song of Ice and Fire 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 breast-fed at age six, and with the ultimate result that he's a budding Caligula, accustomed to annoying guests being executed for his amusement.
Princess Elspeth in the Heralds of Valdemar series was this, to the extent that the Heralds and Court even called her (unofficially) "the Brat." It turned out her nanny was invoking this trope to ensure the grown Elspeth would lack the pure heart necessary to become a Herald and rightful Heir.
Oblomov started 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.
Not even Brother Bear and Sister Bear were immune, in The Berenstain Bears Get the Gimmies. That story had them wanting literally everything whenever their parents took them to the shopping mall - and if they didn't get something, they'd take this trope to embarrassing levels, throwing themselves on the ground and kicking their legs and screaming their heads off.
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.
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.
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.
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)
Live Action TV
Both Lydia and Jackson from Teen Wolf come from very wealthy families who appear to give them whatever they want. In Jackson's case, this includes a brand new Porsche.
The character Madison Penrose in My Super Psycho Sweet 16 was based on these types, only with a long case of Break the Haughtyand, ultimately, Kill the Haughty. Several of her scenes deliberately evoke a number of particularly infamous Spoiled Brat moments from that show.
Sheldon Cooper tends to embody this trope, often getting whatever he wants, how and when he wants it, no matter how unreasonable, merely by being extremely difficult. Ironically, his family seem to be the only people not enabling him.
Which may be part of the reason he's so reluctant to spend time with them, even moreso than the other characters and their respective relatives.
Stingy from LazyTown is so spoiled, he believes that everything he sees belongs to him. He even has a song about it:
"This mailbox is mine / And this triagonal sign The blue balloon / The month of June They’re mine, mine, mine, mine, mine"
Renee of the '90s BBC series Chef! Her father, the nouveau riche owner of Chateau Anglais, makes Gareth take her on to work in the kitchen even though she can't even chop a carrot, and she whines, complains and generally throws a fit any time she's expected to actually do anything.
Daughter of the Rich Bellamys, Elizabeth, from the 1970's BBC series Upstairs Downstairs. She often has stints of protesting for social reforms for the poor and women, yet treats her "friend" and servant, Rose, like dirt. She often complains of having a horrible life, being so rich and having nothing to do, and saying how great Rose has it. Including right after the episode where Elizabeth got Rose sent to jail by accident, where she was starved and tortured, and then sent back to work like nothing happened.
Doctor Who gave us another male example in the Sontaran two-parter "The Sontaran Strategem"/"The Poison Sky". Said kid was actually a teenager, but due to wealth and extreme intelligence had been getting everything he wanted his entire life. The Doctor notes that people haven't said "no" to him in a very long time.
Rachel's sisters Jill and Amy on Friends are both very, very much this.
Rachel herself is also this when we first see her, but she gets better.
Abby Sciuto from NCIS tends to act like this, whining and forcing others (mostly Timothy McGee) to do what she wants with no regards to rules or laws, with Gibbs enabling her and tending to blame and punish others for her mistakes (once again McGee).
In The Insect Play, the ichneumon larva doesn't like the several freshly killed crickets her Daddy brings her every day.
Prince Laharl from Disgaea: Hour of Darkness. He initially refused to pay his vassals because "That's my allowance! Nobody's touching it!" Even after Etna goads him into paying, he opts to steal the funds instead. He eventually does shape up a little, mostly because The Lancer made it clear that she was perfectly willing to off him and take his place if he didn't.
Rozalin from Disgaea 2 fits this as well, except she's a lot nicer than Laharl. Still quite a brat, but nicer.
The RPG My World My Way takes this to its (il)logical conclusion, where a Spoiled Brat princess is the main player character, and can actually progress through the game by pouting to make the world bend to her will. Monsters attacking too quickly? Shout "Ladies first!" and the princess will get the first attack. Quest too challenging? Throw a fit until someone agrees to do it for you.
The spoiled brat in the auction house in Final Fantasy VI is the number one reason you never get to have any model airships or talking chocobos.
Remilia Scarlet is considered Touhou's poster child for a spoiled brat. A 500+ year old vampire with a perpetually 11-year old temperment and a Hyper Competent Sidekick for a head maid. What Remilia wants, Remilia gets.
Tenshi is also something of a Spoiled Brat, with emphasis on the spoiled. She also has such a silver spoon on her tongue that she was bored to death prior to the events in Scarlet Weather Rhapsody.
Recurring NPC Flambeaux from City of Heroes is utterly self-centered and unconcerned about anything that doesn't directly affect her. She became a superhero solely for the attention and adulation she expected she'd receive. And when she didn't get as much as she thought was her due, she became a villain and started terrorizing journalists into publishing worshipful articles about her.
Tales Of The Abyss has this as a major flaw in Luke's character until he becomes The Atoner. It was so bad that all the other characters were surprised when they each first heard him say "Thank You."
Isheil (Breshen's daughter) in Juathuur. She drinks a small dose of poison because her father won't come to her birthday. And dies in agony.
Angelica Pickles of Rugrats was intended to originally be this, by co-creator and former writer Paul Germain. There is an episode of the earlier seasons, where Drew takes a quiz to determine whether or not her child is a spoiled brat, and Drew worries a ridiculous amount. However, given and hinted that Lipschitz is a "crackpot", Drew decides to not take his advice, and return back to normal.
Believe it or not, she is not much of one, even in the episodes where Germain was involved as head writer, her parents would punish her, and not reward her. Though, more so in the later episodes, remaining the first two creators.
Lemongrab of Adventure Time definitely counts. If he doesn't get what he wants (be it a reasonable or unreasonable demand), SOMEBODY is going in the dungeon. There are many reasons for his sour personality (mental illness, stupidity, immaturity), but he was raised in a castle in which everything was handed to him. That probably didn't help him much, in the long run.
Male example: there's a bratty boy named Gavin who sometimes appears on The Simpsons, bawling out his mother if she displays any reluctance to cater to his latest whim. He frequently refers to her by degoratory names such as "Stupid" on a casual basis as well.
Bart Simpson himself used to come off this way, if only by default because he was so disobedient and disrespectful but never seemed to get punished severely for these actions. One episode played this up by having Bart repeatedly play pranks and pull obnoxious stunts, leading his teacher to demand that Marge and Homer discipline him. Marge really did try, but her efforts were all futile because Homer constantly felt sorry for Bart and would undo Marge's punishments when she wasn't there.
Wendy O. / Kootie Pie Koopa from the various Super Mario Bros. cartoons is a huge example. One of her catchphrases is simply "I WANT IT! I WANT IT! I WANT IT!" (See for yourself!) She once demanded, and was given, Antarctica, and then briefly demanded to be Empress of America.
Shapey in Moral Orel. Bad enough he seems to have a behavioral problem, his parents (and Orel, by their command) turn a blind eye to his destructive behavior, and cater to his every whim, lest the neighbors complain about his high-pitched screaming. Later on he does grow out of it and in the Distant Finale he grows up to become a decidedly functioning adult.
Clay as a kid qualifies. The reason why he becomes this is because of his religious fanatic mother.
The Love Mummy in Aqua Teen Hunger Force threatens anyone who doesn't give it what it wants with a curse. However, the real curse is that the mummy is a socially inept spoiled brat with no manners.
Eric Cartman of South Park. Here's one of his milder examples:
Cartman: Mom, can you get me some Weight Gain 4000?
Cartman's Mom: Okay Eric. I'll get you some at the store tomorrow.
Cartman: But mom, I need it for tomorrow!
Cartman's Mom: But, tomorrow is grocery day, Eric.
Cartman:Mooooooom *whines incoherently*
Cartman's Mom: Okay, okay. Well, I guess I'll be going to the store now, then.
Cartman: *smiles* Sweet.
American Dad: Roger is referred to as a spoiled brat a few times in one episode, and he and Stan tend to embody this trope whenever enabled, usually by Francine.
Steve and Hayley, the actual kids of the family, have the odd bout of this as well, even if it's more out of defiance of their parents than being spoiled by them.
Jeremy Creek in The Town Santa Forgot: He Starts out spoiled until his parents stop buying him toys, he then gets the idea of writing a HUGE Christmas list to Santa but all the toys he wanted went to a town with his name, thus seeing the selfishness of his ways, he decides to reform, and therefore becomes generous
At least Muffy isn't a TOTAL brat, unlike D.W., Muffy actually learns from her spoiled ways. And just because D.W.'s only four-five years old doesn't mean that's a good enough excuse for all the times she's tormented Arthur.
The Tibbles. Their grandmother is a soft touch and no matter what they do she never punishes them.
A Looney Tunes retelling of the Goldilocks story has a girl mouse encountering three cats - Sylvester, his wife, and his son, who is constantly referred to as a spoiled brat, and that's apparently his name too.
Said son was Sylvester Jr, more known for his appearances in the Hippity Hopper shorts. While not quite as pronounced as in said short, he is often a condescending little know-it-all who whines or expresses shame for his father whenever he doesn't add up to his standards of an ideal role model or formidable vermin chaser.
Fenton in Home Movies, especially during his birthday party. Spoiled Jerk Ass is more accurate.
In one episode, he and his mother were shown eating nothing but rice for dinner, as though it was a regular occurrence. Maybe a nutritional deficiency is partly responsible for his behavior.
Virginia in Lola And Virginia a spoiled Rich Bitch, who was transferred from a private school to a public school, because of her mindset that the whole world revolves around her. She always does everything to get her way and to torment Lola, but she usually gets whats coming to her.
Diamond Tiara and Silver Spoon from My Little Pony: Friendship Is Magic, an Alpha Bitch duo whose names sum up their Cutie Marks. In the MLP universe, your Cutie Mark defines what you're best at; thus, these two are destined to be little more than rich bitches.
Angel Bunny, Fluttershy's rabbit companion, has shown extreme signs of this as of "Putting Your Hoof Down," throwing a violent temper tantrum and actually physically attacking Fluttershy over a salad, of all things.
Pistol on Goof Troop is extremely demanding and is favored by her father. She successfully goaded him into giving her 100 dollars for no reason at one point, despite being kindergarten age.
A season two episode of Jackie Chan Adventures saw Jackie and Jade helping an incredibly rich Man Child search for a mythical lost city. The guy's long-suffering butler had it even worse, as he had to put up with his employer's every demand even after they were both magicallly de-aged.
Jackie: I cannot believe I am stuck in the jungle with such a spoiled brat.
Jade: (hurt) You invited me!
Jackie: I was talking about HIM!
Meg on Family Guy used to be a spoiled brat in the beginning of the series. Like any typical bratty teenaged girl, Meg wanted expensive things like a new car (because everyone else at school has one) or a new purse (because everyone at school had one). Meg would attempt to beg or guilt her parents to get the things she wanted, but it never worked. Ever since Meg became the Butt Monkey of the show, she's shed her bratty tendencies and is much more mature but also a bit crazy.
