Annoying Younger Sibling



The Annoying Younger Sibling is often used by writers as a balance to the "coolness" of the main protagonist. Typically the opposite sex of the main character.

Little brothers tend to be: dirty, good at sports, noisy, foul-mouthed, always get in trouble with authority, perverted. Usually a Bratty Half-Pint.

Younger sisters are usually: whiny, cry to get what they want, too Curious as a Monkey, go headlong into real danger, ALWAYS have tea parties with dolls and one "real" participant, cheeky, nosy. Likely to be a Bratty Teenage Daughter if female and slightly older.

Alternatively, it may be that the younger sibling in question has none of the above attributes, but incurs the wrath of the main characters in equal measure by being cleverer than they are, or by getting a disproportionate amount of (inevitably positive) attention.

Annoying younger siblings of both genders tend to be tag-alongs, especially when they're not wanted. Typically, there will be something of an age gap between the protagonist and the annoying younger sibling, about three to six years on average. Too much of a gap and the sibling will lack the resources to be annoying enough. Too close and you're into Sibling Rivalry territory instead.

Note that this trope is for younger siblings who are annoying to the other characters, not to the audience.

Truth in Television, obviously.

Anime & Manga

 * Shiro Kabuto from Mazinger Z and Great Mazinger was Kouji's little brother. He was a hard-headed, hot-tempered, enthusiastic and nosy tag-along, and a Deadpan Snarker was constantly getting in trouble. Kouji found him annoying every so often, although it also may be because often Shiro seemed more mature than Kouji himself, and often he would point out the stunt his older brother was trying to pull might not be a good idea.
 * Goro Makiba from UFO Robo Grendizer was also considered like a little pest for his older sister -Hikaru Makiba-. He was poking his nose where it did not belong and making remarks nobody had asked for, mainly about her relationship with The Hero Duke.
 * Tsukino Shingo from Sailor Moon; he was actually quite tolerable and likable, but like many other extras, he vanished over the show's run. The Annoying Younger Sibling role was taken by Chibi-Usa, who immediately partnered with Shingo to make Usagi's life hell. (posing as the main character's cousin, but actually her Kid From the Future), whose actual involvement in the plot (so much so that she got her own season) made her a little too annoying.
 * Which was a damn shame because Shingo was actually a fairly interesting character when they bothered to show him, it was actually more of a case of Annoying Older Sibling.
 * Ryouta Misumi from Futari wa Pretty Cure is... Shingo Tsukino reincarnated or something, considering how he acts towards Nagisa. He even mirrors Shingo's feelings towards his sister's smartass friend Ami, with his own feelings towards Honoka.
 * And Yuu and Ai Natsuki in Yes! Pretty Cure 5 are Ryouta in stereo as Half-Identical Twins.
 * Momiji in Cross Game... from Aoba's perspective.
 * Harukaze Pop in Ojamajo Doremi, who, like Chibi-Usa, ends up joining the main group.
 * Spritle in Speed Racer.
 * Shizuku from Candy Boy initially appears to be quite unpleasant to her older sister Kanade. She becomes less annoying once we see the reason for her behavior, though.
 * Kyon's sister in Suzumiya Haruhi approaches this sometimes. More often she's just how kids her age are... sometimes a little annoying, sometimes cute.
 * May's brother Max in Pokémon. Naturally, his know-it-all attitude annoys the heck out of Ash and May, but he improves as they go through Hoenn and the Battle Frontier in Kanto.
 * To be fair to Max, he was 8 when introduced so he can't apply his Pokemon smarts. He'd likely be less annoying if he were to show up again with his own Pokemon team.
 * Axis Powers Hetalia has South Korea and Sealand respectively annoying China/Japan and England. In Korea's case, he seems to genuinely love his older brothers. A bit too genuinely.
 * Hetalia also gives us Belarus, though she's more of an Axe Crazy Younger Sibling.
 * England may or may not be one of these as well, to Scotland, Wales, and (presumably) Northern Ireland.
 * Northern Ireland would be younger than England. Maybe they'd be an example of this trope to Ireland?
 * Kyoko from Dennou Coil is this through and through, giving her older sister Yasako major headaches throughout the series.
 * Keiko Sasahara in Genshiken is a teenaged example, her gyaru lifestyle and her pompous attitude standing in stark contrast to that of her much more level-headed Otaku brother Kanji. Her personality is also a deliberate subversion of the idealized Moe portrayal of younger sisters.
 * Mokuba Kaiba, from Yu-Gi-Oh!
 * Shut up, Mokuba!
 * As Karluk from Otoyomegatari lives with his rather large family, this is 19th century Turkey after all, his many nieces and nephews fit this trope strongly.
 * Not a sibling, but for the rest Ed from Cowboy Bebop fits this trope to a T.
 * Durarara reveals that, of all people, has a pair of teenaged twin sisters named Mairu and Kururi, whom he abhors. Of course, this seems only to concern him because everyone else likes his twin sisters over him: they're a little off their rockers, but as long as you don't upset them, they're fairly Moe. Even
 * In Tamayura, Fuu's younger brother Kou is generally rather sweet and cute, although he clearly has his more annoying moments. That doesn't prevent Fuu from caring a lot for him, though.
 * Bud Hanson from Transformers Cybertron tends to get on his older brother Coby's nerves from time to time.

Comics

 * Needless to say, Newspaper comics featuring families are quite fond of this trope. Leads to a lot of humour.
 * The comic strip Curtis had one of these.
 * Hammie jumps in-and-out of this in Baby Blues.
 * Can't mention sibling rivalry in connection with comic strips without mentioning Lucy and Linus van Peldt from the Peanuts series.
 * To a somewhat lesser extent, Charlie Brown and Sally.
 * Averted in PS238, despite most of the main cast being preteens. Suzie Finster is however a straight example, being younger than the rest of the class. Also, a walking nuclear reactor with an internal body temperature that can melt lead.
 * From Batman, Tim Drake sees Damian Wayne in regards to this.

Films -- Live Action

 * Just pick ANY teen movie.
 * Amy from Disney's Minutemen.
 * Despite the fact they are adults, Tom Chamberlian is played this way in Gettysburg for his brother Joshua "Don't Call Me Lawrence" Chamberlain. Historical records say he was probably quite different in Real Life.
 * Samantha's brother, Mike, in Sixteen Candles.
 * Mikey (and his friends) is this to Brand in The Goonies. Their mother charges Brand with keeping an eye on Mikey during the day, which he's none too thrilled about. Mikey and co. escape by tying Brand to a chair and then he has to track them down. Mikey also accidentally steals Andi's First Kiss from Brand. A bit of a subversion as Mikey is the protagonist.
 * Sherry's little brother in Matinee.
 * Dani in Hocus Pocus. The Nostalgia Chick calls her a "beastly child".

Literature

 * Suzie from Enid Blyton's The Secret Seven.
 * Ramona from the Henry Huggins series by Beverly Cleary.
 * And then, ironically, Ramona got her own series and Beezus was relegated to periodic appearances.
 * In her own series, Howie's sister, Willa Jean, is to her what she used to be to Henry
 * Fudge in Tales of a Fourth-Grade Nothing by Judy Blume, who also begins as mere sibling but ultimately becomes star of a series.
 * Dairine of the Young Wizards series serves as Nita's annoying younger sibling, albeit a younger sibling who's annoying because she's actually smarter and stronger than her older sister.
 * Clark in Robert Heinlein's Podkayne of Mars, younger brother of the title character. A subversion because in the end he's actually much smarter and sophisticated than his older sister (and most adults), and ends up saving her life.
 * Only in the forced rewrite his publisher made him do. In the original version, she died. Heinlein considered Clark to be pretty much a sociopath. It was Clark's fault that she was in any danger at all.
 * Todd Lyons from The Clique.
 * Tiffany Aching's younger brother, Wentworth in The Wee Free Men by Terry Pratchett. He gets better as he grows older, though.
 * Several Greek gods act like this in Percy Jackson. Most notably Artemis; although she can't really say her "Annoying brother" is younger; since Apollo is her twin.
 * Sadie Kane of The Kane Chronicles has to be one of the most annoying younger siblings of all time - and the most dangerous.
 * technically she can, because she was born a few minutes before her brother. And immediately midwifed her mother during his birth. ... She was a precocious kid.
 * Manny of Diary of a Wimpy Kid is practically the human incarnation of this trope. If he lived in any of your families, chances are he wouldn't survive preschool without being the victim of fratricide.
 * They're not children, but Maedhros and Maglor from The Silmarillion have really annoying younger brothers. Well. Not so much annoying as liable to start a war with everyone, including their own family and supposed allies.
 * Taken to a whole new level with Briony Tallis in Atonement.
 * Nearly every Goosebumps protagonist has one. Special mention to Tara from "The Cuckoo Clock of Doom"
 * Fudge Hatcher of the Tales Of A Fourth Grade Nothing series. He makes more trouble than any character in the series, but almost never gets told off for it. Not even after he ate Peter's turtle on purpose. The worst that could happen would be that he was constipated, it wasn't like he'd die!
 * The 39 Clues has the (admittedly VERY awesome) Dan Cahill. Even though he can be annoying sometimes, his talents, especially his Photographic Memory can come in handy. Natalie Kabra is one to her brother, Ian. While he definitely does care for her, it is said in one of the books that he doesn't "even like Natalie."
 * Harry Potter: even though Fred and George are older than Ron, they still fill this trope for him. They are the Class Clowns of the entire school, after all. However, they seem to think of Ron as this trope as well. Percy, likewise, thinks the same of every sibling younger than him, with equally mutual feelings.
 * During the events of The Lost Colony, Artemis Fowl gets transported to a different dimension. When he comes back, he finds out what felt like just a few hours for him, was actually three years in our dimension. He comes back to find his family has expanded in those three years, as he now has two younger twin brothers: Miles and Beckett Fowl. He seems to love them-- as much as Artemis can show love, at least-- but they do make him feel a little frustrated when he's trying to instruct the three-year-olds in modern languages, and they seem more interested in worms and calling each other "simple-toon."
 * Also Juliet to Butler in the first book, before she Took a Level In Badass.
 * Captain (later Major, later Commander) Trouble Kelp is the LEP's "Golden Boy" for a reason. Corporal Grub Kelp is named "Grub" for a reason. The latter may involve filing complaints over hangnails and saying "Mommy said" on the battlefield.

Live Action TV

 * I'm Telling, a kiddie variant of The Newlywed Game that aired on NBC's Saturday morning schedule in 1987-1988; this show lived on pairing older and children and their annoying younger siblings, with many of the questions stylized to play upon this trope (not to mention begin arguments). Bob Eubanks-wannabe Laurie Faso (yep, he was a "he") was the host of this pale clone of the real thing, audiences agreed and it didn't last past one season. The child contestants (all ages 8-16, and stereotypical even by late-1980s standards) HAD to be embarassed when it showed up in reruns on the Family Channel from 1994-1996.
 * Little House On the Prairie: Carrie Ingalls, the third daughter of Charles and Caroline Ingalls, and in many episodes a thorn in the sides of Mary and Laura. Even though Carrie didn't get the spotlight very often, there were two specific episodes where the spotlight shined on her:
 * 1976's "Little Girl Lost": During a butterfly hunting expedition, she pesters her sisters to the point they want her to go away. She does -- almost permanently, when she plummets down a sinkhole that leads into an old mineshaft.
 * 1978's "The Godsister," where Carrie -- heartsick for her Pa (after Charles -- along with Jonathan Garvey -- take jobs on a telephone crew, which will bring service to Walnut Grove) -- begins bothering her sisters and Albert (who by now was part of the cast), and also Nellie and Willie Olesen and Andy Garvey to play with her. When they refuse, Carrie invents a "friend" of her own: a girl named Alyssa. This episode featured both Lindsey and Sidney Greenbush (the identical twins that played Carrie) in the roles of Carrie and Alyssa.
 * The Brady Bunch: While in most episodes the siblings got along, there were a few whose plotlines fit the trope:
 * "The Tattletale," where Cindy seeks attention by ratting out her siblings. Mike and Carol counsel her several times on her behavior and warn her to stop. In the end, Cindy doesn't want to rat out Tiger when he swipes out a claim voucher that would allow Alice to pick up her stereo. (The subplot saw Alice enter a jingle contest for an electronics store, and she won.)
 * It is unknown if other more serious instances where Cindy would be expected to tell the truth -- i.e., the mailman behaving inappropriately with one of her sisters -- but supresses it for fear of being punished by her parents, were considered. This episode was filmed in the fall of 1970 and the network likely would have been nervous about airing such a plotline, hence the seemingly awkward subplot using the by-now nearly forgotten Tiger (in his last appearance, after making sporatic appearances over the previous year or so).
 * "The Teeter-Totter Caper," at the end of 1971, when Bobby and Cindy -- already having not been invited to their Aunt Gertrude's wedding -- want to help their older siblings but are told to stay out of the way. (The older siblings telling Bobby and Cindy to go away, they're being annoying isn't seen on camera, but it is referenced by the downbeat pair of youngest siblings.) Mike tells the two that perhaps there are times where their help isn't necessarily needed or wanted and they should find something to do, leading to the main plot of the youngest Brady siblings setting out to prove they aren't annoying younger siblings ... by setting out to break a world teeter-tottering record.
 * "Law and Disorder" -- Bobby is named Safety Monitor at school, a position which entrusts students with good behavior records in helping enforce school rules (in essence, the students police themselves). The trope comes into play when he carries over his authority to home, where he spies on his siblings and tells them he plans to tell Mom and Dad. (For instance, he sees Greg come home late for a date, refusing to even let him explain that Greg had waited at home with his date until her parents arrived home; or Alice -- a non-sibling, but still -- setting out aerosol cans with the rest of the garbage, not even letting her explain that the waste collecter had a new policy on how trash should be sorted.)
 * "You Can't Win Them All," where Cindy -- having won her way on a local College Bowl-type game show (modeled into a version for older elementary-school students) -- gets an inflated ego and annoys her siblings about being the next big star. Naturally, she gets her comeuppance in the end when she suffers from stage fright.
 * "Never Too Young," where Cindy (again!) is the annoying pest. This time, having (unknown to Bobby) witnessed a classmate named Millicent (Melissa Sue Anderson, in an early TV role) kiss Bobby on the cheek for defending her at school. Cindy annoys her siblings by singing, "I've got a secret! I've got a secret!"
 * Disney Channel loves this trope, that almost all of its live action shows would at least have one. Examples:
 * Matt from Lizzie McGuire, who to some is actually much cooler than Lizzie. But to be fair, like most of Disney Channel tween show protagonists, she was designed to be a loser.
 * Ditto for Flynn from Shake It Up, due to being Matt's Expy, and being less annoying.
 * Jackson from Hannah Montana functions as an Annoying Younger Sibling; although technically he's older than Miley, much is made of him looking and acting younger.
 * Cory from That's So Raven.
 * Max Russo in Wizards of Waverly Place.
 * Justin tends to feel like this about Alex, too.
 * Brian from Adventures in Wonderland.
 * Ferguson from Clarissa Explains It All.
 * Gaby Fernàndez from Ghostwriter.
 * Shelly from Parker Lewis Can't Lose.
 * The little sister of the titular Drake and Josh isn't just annoying... she's evil.
 * Ditto Pim in Phil of the Future, although in a less Villain Sue kind of way.
 * It sort of is and isn't subverted in My Parents Are Aliens. Lucy due to her cleverness and, in particular Josh with his mischievous behaviour, fit the trope quite well for Mel (just as she, with her aggressive and sarcastic attitude, sort of does for them), but there is also Brian, since, despite being their foster-father is able to morph into any one of the siblings at will (though usually only when asked) and can cause "annoying" problems in that sense. Also, since he and Sophie are not from planet Earth, the role of an adult using experience to explain things to a clueless child is generally reversed from the parents to the children throughout.
 * In the French instructional series French in Action, chocolate-scoffing Marie-Laure, sister to Mireille, fits this trope to a tee. Her major function is to irritate Mireille, while somehow charming everyone else around her.
 * Lyle, Claire's younger brother on Heroes.
 * Nickelodeon's My Brother and Me had the two main characters, Dewey and Alphie, filling this role. Dewey was the annoying sibling to Alphie, and Alphie and Dewey were the annoying siblings to oldest child Melanie.
 * Kyra on Kenan and Kel, who played this to Kenan and crushed on Kel.
 * Dawn, from Buffy the Vampire Slayer.
 * Sarah from Radio Active.
 * Nate in Burn Notice.
 * Much from Robin of Sherwood.
 * From Life with Derek, we have Marti and Edwin. Although, to be fair, all five get their fair share of "annoying" at times... including the older ones.
 * Patty Pryor in American Dreams.
 * In Young Dracula Vlad fits the trope for Ingrid, just as she, though older, covers the "annoying" bit for him: he doesn't want to be a vampire but is still favoured by his father and she does want to be one but is ignored. Olga, although she is a cousin rather than a sibling of theirs, likewise fits the trope for Ingrid because of her competitive streak.
 * Vlad's friend Robin Branaugh, due to his semi-gothic persona and obsession with vampires is something of an annoyance to his elder siblings Ian and Paul (and vice versa) and although his sister Chloe is younger, her brothers tend to fit this trope for her since she is generally more mature and academically bright.
 * Bud Bundy on Married... with Children.
 * Although both characters are adults, Juan is definitely this to Cesare in The Borgias. It doesn't help that Juan gets to be a soldier (as Cesare always wanted to be) and is heir to the family estate while Cesare, though older, and far more competent, has to follow in his father's footsteps by becoming a Cardinal. But on top of that, Juan's really, really aggravating.

Stand-Up Comedy

 * Bill Cosby has a routine called "My Brother Russell," revolving around a terrible night trying to sleep in the same bed as his youngest sibling.

Video Games

 * Ronny Dobbs of the Backyard Sports series definitely fits this trope, a balance to his sister Sally.
 * Inverted in Mana Khemia 2 Fall of Alchemy with Cloudcuckoolander Et being the source of irritation for her closer to Earth younger brother Enna.
 * In Night Trap, there is Danny, Lisa's little brother.

Web Comics
"Pandora: Hey squirt, where's your big sister? Abigail: He's back to being my big brother now... pfft... in a dress. Pandora: Please tell me you took pictures. Abigail: Uh, yeah! It's my job as a little sister."
 * Ruby in Monsterful: She's really a very classic example... maybe except for the fact that she is also extremely cunning and evil (specially for a 4 years old), she loves to drive her mother Diamond crazy, make her own father cry and torture her older sisters, oddly enough she loves and respects her older brother Onyx. Almost set fire her mother on fire, made her crash and who knows what else. Deep inside she's just a cute little vampire girl, with tons of evil to share!
 * All of Cy's younger siblings in Boy Meets Boy.
 * Timulty in Ozy and Millie is Avery's Annoying Younger Sibling, though he's portrayed much more sympathetically than a lot of these examples, perhaps because Avery has a tendency to be a rather unsympathetic character....
 * The Cyantian Chronicles: During Akaelae, Darius and little brother Ravon. During Campus Safari, Darius and little sisters Tae and Kea. Inversion: Quinn is older than Collin, but still manages to be an annoying little sister to his levelheaded "older" brother.
 * A sort of subversion exists in the form of Monette from Something Positive. It's not played quite straight, in that Monette was adopted (as an adult no less) into the MacIntire family and is not so much obnoxious as a Cloudcuckoolander.
 * Ki's brother Yoshi in General Protection Fault.
 * Zoe's sister Min from Sluggy Freelance. She seems to be a pretty cool person most of the time, but becomes ultra-annoying when she goes into Stalker with a Crush mode (mainly focused on Riff).
 * Ben's little brother from Loserz. See here.
 * Wooden Rose: Nessa is no help at all.
 * Julia Greenhilt, little sister to Roy from Order of the Stick, is the bratty teenage version; she's 12 years his junior, but still manages to annoy him by being mouthy, an Attention Whore, and dressing in Stripperiffic clothes. Despite all this, it's clear they really do love each other.
 * Orange Marmalade has Ma-ri's younger brother, Joseph, a bratty half pint vampire kid who causes her family to move several times by blowing their cover. Doesn't stop Ma-ri from falling into a Pet the Dog moment with him every once in a while. Every once in a long while.
 * Angelika, in Our Little Adventure, though her older sister Julie can be quite annoying to some as well.
 * Nina in Eerie Cuties. Layla loves her little sister and is very protective, but... no matter how adorable, being overexcited and a little out of it most of the time has this effect.
 * Abby in Dangerously Chloe. She's helpful, caring and quite sure that it's her duty to mock and/or embarrass her brother as often as possible.

Web Original

 * Maybe half the main characters in the webfiction Whateley Universe have an Annoying Younger Sibling who ranges from "pretty normal but wishing he had a superpower too" (Chaka's little brother) through "bratty behavior that accidentally poisons the protagonist" (Tennyo's younger brother) all the way up to "calling out a heavily-armed squad of anti-mutant soldiers and sicking them on protagonist" (Lancer's younger brother).
 * Marie is this in Erika's New Perfume, but at the same time she looks at Erika as such. It's complicated.
 * In the Global Guardians PBEM Universe, former Guardian Bandit has an Annoying Younger Sibling in the "Roger Clinton/Billy Carter" way: Ozcar Vizcairno is an irresponsible adult whose outrageous statements and actions always seem to land him on the front pages of the tabloids... not to mention utterly shredding Bandit's Secret Identity.
 * Subverted with The Nostalgia Critic. While he is annoying, his big brother The Other Guy slaps him around and controls him for no reason other than for fun.

Western Animation
"Dash: She'd eat if we were having "Tony-loaf."
 * D.W. in Arthur. To his chagrin, all of Arthur's friends and just about everyone they meet take a liking to her.
 * Pistol Pete, younger sister of PJ in Goof Troop.
 * Ray Ray from The Life and Times of Juniper Lee is everything a little brother shouldn't be.
 * Haley in American Dragon Jake Long.
 * Quinn in Daria.
 * Also Sandi's two younger brothers, and Brittany's younger brother (whose brattiness Brittany outright relies on in a first season episode in order to sabotage Daria and Kevin's school project).
 * Christopher (to Irma) and Lillian (to Cornelia) in WITCH. As it turns out, Lillian is actually kind of a sweetie, and only acts the way she does half the time because Cornelia is mean to her.
 * Jim and Tim (the "twin dweebs," or "tweebs") in Kim Possible.
 * In Code Lyoko, Hiroki Ishiyama to his sister Yumi. Not just a Bratty Half-Pint, but also a Honest John in training.
 * John, Chris' brother, in Monster Buster Club. He's not bratty so much as overly enthusiastic, what with his always wanting to join the MBC and all that. (The real question is why they don't let him, since he gets along with everyone there and has proven himself useful doing the things they normally do.)
 * Word Girl's younger brother, TJ.
 * An interesting case in that the main character of Danny Phantom used this exact trope to get his sister Jasmine aka Jazz to embrace her childhood (she thinks she is an adult in a teen's body) and subsequently get her to see a ghost only visible to children. He rarely at times act this way to Jazz prior to "The Ultimate Enemy", but that's because he's too old to be the typical annoying younger brother.
 * Matt from Batman Beyond is a major thorn in the side to his big brother Terry, but not as bad as most of the other examples on this page. They do get plenty of cool brotherly moments together to offset the times he acts like a little hellraiser.
 * Codename: Kids Next Door has Numbuh Two's little brother Tommy, who didn't make a good first impression when he caused them all to catch the flu while fighting the Common Cold due to being extremely distracting. He's only gotten worse with him assuming the mantle of "The Tommy", a vigilante adult-fighter that's more or less a Boring Failure Hero.
 * Also Numbuh 3's younger sister Mushi.
 * Daggett Beaver of The Angry Beavers, who's technically the younger sibling by several seconds. He means well, but he's impressionable and incredibly high-strung.
 * Inverted in Dexter's Laboratory, where the annoying Dee Dee is actually Dexter's older sister.
 * Sweetie Belle and Apple Bloom in My Little Pony Friendship Is Magic became well-intentioned but annoying siblings when they tried to help their older sisters with their work. Sweetie Belle's "help" in "Stare Master" lead to a huge mess in Rarity's workshop, all from Sweetie Belle trying to fetch a spool of ribbon. Likewise, Applebloom's "help" in "Call of the Cutie" forced Applejack to give away a bushel of apples to an annoyed customer.
 * In Avatar: The Last Airbender, Azula was this to Zuko when she wasn't trying to kill him.
 * Brianna is this to the titular character of Kick Buttowski, while their older brother Brad seems to regard Kick as this.
 * Dash of The Incredibles fame, at least from Vi's point of view.

Vi: THAT'S IT! *launches herself at Dash*"


 * Max and Ruby seems to be based on this trope. Granted that Ruby is VERY patient and Max is quite equally annoyed by her forcing him to do what she wants most of the time.
 * Chis to Meg in Family Guy. Stewie can be to both, although it is usually not as big of a deal because he's a baby. For example, Meg was only mildly annoyed when Stewie stole her gifts at her birthday party.
 * Phineas (and to a lesser extend, Ferb) were originally meant to be this to Candace. You can see remnants of this in the first episode, where Phineas is a lot snarkier and goes out of his way to antagonize his sister. But Characterisation Marches On, and now they're much more likely to want to help Candace out than annoy her.

Real Life

 * Joseph Bonaparte had a younger brother; his name was Napoleon. Napoleon kept conquering half the world and tried forking countries over to Joseph to handle, but Joseph just wasn't as talented at the world conquest thing....
 * He was arguably more talented at trying to be a Nice Guy sometimes, and that's more important.
 * Billy Carter, the alcoholic, slightly racist brother of President Jimmy Carter, seemed born to become tabloid-bait.
 * Same with Roger Clinton, younger brother of President Bill Clinton.
 * And you probably once fit into this trope too, if you were the youngest in your family. This troper certainly did.
 * And if you were the oldest, no matter how angelic your younger sibling may have been, you probably at some point felt they belonged in this category.
 * Angelina Galgani, younger sister of Saint Gemma Galgani. In her memoirs, Gemma recalls how Angelina and her school friends used to mock her because of her alleged visions, and many years later she was declared unfit to testify in her older sister's canonization process due to accusations of attempting profit from Gemma's reputation (and apparently, her relics.)
