-->-- ''WebAnimation/TheMostPopularGirlsInSchool'', Episode 7

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, [[MouthyKid foul-mouthed]], always get in trouble with authority, perverted, and just about always grabby when they see something their older sibling has that they don't, who will probably shriek "[[ItsAllAboutMe gimme gimme]]" and [[TheKlutz break it]] if they get their mitts on said object. Usually a BrattyHalfPint.

Younger sisters are usually: whiny, cry to get what they want, [[ConstantlyCurious too]] {{curious|AsAMonkey}}, [[PluckyGirl go headlong into real danger]], [[TheDreadedPretendTeaParty ALWAYS have tea parties with dolls and one "real" participant]], cheeky, nosy. Likely to be a BrattyTeenageDaughter if older than the standard.

Alternatively, it may be that the younger sibling in question has none of the above attributes, but [[SitcomArchNemesis 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 [[TagalongKid tag-alongs]], especially when they're [[MostDefinitelyNotAccompanyingUs not wanted]]. Typically, there will be something of an age gap between the protagonist and the annoying younger sibling, about three to six years in general. Too much of a gap and the sibling will lack the resources to be annoying enough. Too close and you're into SiblingRivalry territory instead. Taken to the extreme and you will see a CainAndAbel scene, or in worst, a case of SiblingMurder.

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

TruthInTelevision, obviously.


[[folder:Anime and Manga]]
* Amy from ''Anime/AiNoWakakusaMonogatari'' is a major example.
** Meg's son and daughter also count.
* ''Manga/AkatsukiNoAria'' has Ayako Nishimikado, Natsuo's SpoiledBrat of a little sister who treats their half-sister and our lead character Aria quite badly. Hilariously, when Natsuo's RichBitch arranged girlfriend Beniko appeared, ''both'' Aria and Ayako [[TerritorialSmurfette hate her on sight.]]
* ''Manga/AxisPowersHetalia:''
** South Korea and [[CheerfulChild Sealand]] respectively annoying China/Japan and England. In Korea's case, he seems to genuinely love his older brothers. [[BrotherSisterIncest A bit too genuinely]]. As for Sealand, he turns into a BrattyHalfPint around England; he constantly refers to him as "jerk England," and goes out of his way to boast that one day he's going to to be an empire greater than England ever was.
** ''Hetalia'' also gives us [[{{Yandere}} Belarus]], [[PsychopathicManchild Russia's]] younger sister, who [[StalkerWithACrush obsessively stalks him]] in an attempt to [[BrotherSisterIncest get him to marry her]],[[note]] To which Russia wants [[AbhorrentAdmirer absolutely no part of]][[/note]] and can be quite AxCrazy about it. Notably, [[LoveFreak America]] also views her this way [[AllThereInTheManual according to notes]], as he had to take care of her for a time.
** [[{{Tsundere}} South Italy (also known as Italy Romano)]] views his younger brother, the LovableCoward and [[TheDitz ditz]] North Italy, this way, though Romano also has an inferiority complex aimed toward his brother, and is a grumpy PerpetualFrowner.
** [[{{Trickster}} Hong Kong]] and [[BrattyTeenageDaughter Taiwan]] love annoying their older brother and BigBrotherMentor [[ImmortalImmaturity China]]. They constantly mock him, calling him "old," and make fun of his [[OneOfTheKids attempts at being "young, hip, and cool."]] Hong Kong also loves annoying England, whom he used to live with for a time, according to one of his profiles.
* As Karluk from ''Manga/ABridesStory'' lives with his rather large family (this is 19th century Turkey after all) his many nieces and nephews fit this trope strongly.
* Shizuku from ''Anime/CandyBoy'' initially appears to be quite unpleasant to her older sister Kanade. She becomes less annoying once we see the reason for her behavior, though.
* ''LightNovel/ACertainMagicalIndex''
** Mikoto's cloned sisters, who are younger than her chronologically, [[YoungerThanTheyLook if not in appearance]], sometimes troll her, and one of them once stole her ice cream. One of them hangs a lampshade on the trope [[http://mangafox.me/manga/to_aru_kagaku_no_railgun/v06/c039/11.html here]].
--->'''10032:''' It is a big sister's duty to listen to the selfishness of her younger sister, Misaka says as she applies brainwashing to a young girl.
** The Sisters themselves have this dynamic with their "administrator", Last Order, who is physically younger than they are, and is hyperactive, impulsive, and can sometimes be rather irritating. Witness Misaka 10032's reaction to Last Order stealing her electro-vision goggles - she cocks her Airsoft gun and goes on the hunt.
* In ''Anime/{{Charlotte}}'', Ayumi is this to Yu, often pestering him with questions.
* In ''{{Manga/Citrus}}'', Mei, while her new step-sister Yuzu is a couple months older, certainly has no trouble viewing Yuzu as this due to the former acting more mature than the latter.
* Momiji in ''Manga/CrossGame''... from Aoba's perspective.
* Matt, Ian's younger brother and Jeremy's younger step brother from ''Manga/ACruelGodReigns''. He is also the BrattyHalfPint.
* Kyoko from ''Anime/DennouCoil'' is obsessed with yelling "poop!" and always runs into trouble, giving her older sister Yasako major headaches throughout the series.
* ''LightNovel/{{Durarara}}'' reveals that [[spoiler:Orihara Izaya]], 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 [[CuteAndPsycho a little]] [[CreepyTwins off]] [[SingleMindedTwins their rockers]], but [[BewareTheNiceOnes as long as you don't upset them]], they're fairly sweet and even {{Moe}}. Even [[spoiler: [[InterGenerationalFriendship his sworn rival Shizuo]] thinks so.]]
* Inverted in ''Manga/{{Fullmapla}}'' with Makoto's {{Cloudcuckoolander}} older sister, Sumi (to the point that even thinking about her sister gives Makoto an exasperated look).
* ''Manga/FullmetalAlchemist'' averts this in the present day - Edward and Alphonse are the most devoted brothers you could imagine - but it's seen in a short (manga only) story taking place in their young childhood. As a toddler, Ed was horrible to Al, smacking him with books and pushing him. Al wasn't really any more annoying than any other baby, but he was the trope to Ed due to the latter's misguided belief that their mother loved her younger son more. After their father talked to him about it, Ed got better.
* In ''Manga/GakuenBabysitters'', Hayato Kamitani's annoying younger sibling is Taka, who is loud and boisterous to everyone he talks to, including him. Kamitani often smacks Taka on the head whenever he gets particularly bad in this regard or otherwise misbehaves.
* Keiko Sasahara in ''Manga/{{Genshiken}}'' is a teenage example, her ''[[UsefulNotes/SubculturesInJapan 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.
* ''Creator/GoNagai'' has several:
** Shiro Kabuto from ''Anime/MazingerZ'' and ''Anime/GreatMazinger'' was Kouji's little brother. He was a hard-headed, hot-tempered, enthusiastic and nosy tag-along, and a DeadpanSnarker 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 ''Anime/UFORoboGrendizer'' 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 TheHero Duke.
* Yan Ming manages to be this for Lan in ''Literature/HalfPrince'' despite being less than a day younger than her.
* Kyon's sister in ''LightNovel/HaruhiSuzumiya'' approaches this sometimes. More often she's just how kids her age are... sometimes a little annoying, sometimes cute.
* Very much present in ''Manga/HimoutoUmaruChan''. While Umaru may present herself as TheAce to the outside world, at home (and with her big brother Taihei) she is a LazyBum who would rather pig out on snacks, watch anime, and play video games. Much of their interaction is Taihei trying to get Umaru to straighten up or at least clean up after herself.
* Yori in ''Manga/InsideMari'' is a main character example. Her older sister Mari ([[OneSteveLimit not the titular character]]) doesn't quite like her moody teenager attitude.
* In ''Anime/KujiraNoJosephina'', BrattyHalfPint Rosa was this to the protagonist Santi. Then again she's five years old tops when he's around 11-12...
* Seki of ''Manga/MyNeighborSeki'' treats his kindergarten-aged sister Jun this way. He scoffs at or ignores her attempts to join in his elaborate games and only reluctantly takes care of her when they're together. However Yokoi adores Jun so she, and thus the narrative, takes Jun's side, voluntarily being a playmate and helping her when she and Seki get competitive.
* Hanabi is presented as having a mild case of this in ''Anime/TheLastNarutoTheMovie''. Hinata notes in the book adaptation that Hanabi wasn't this way in the past, and her limelight episodes show so. [[spoiler:She became more cheerful as a response to Neji's death.]]
* Ririka's little brother Shou from ''Manga/NurseAngelRirikaSOS'' can annoy her however they still obviously care for each other. When Shou gets kidnapped by Dewey, Ririka's BigSisterInstinct kicks in. Also, when Shou upsets Ririka a bit ''too'' much he becomes worried about how to make it up to her.
* Harukaze Pop in ''Anime/OjamajoDoremi'', who, like Chibi-Usa, ends up joining the main group.
* Sorata's little sister Yuuko in ''LightNovel/ThePetGirlOfSakurasou'' visits Sorata at a most inopportune time (just when he was waiting for the results of his video game thesis) to pester him with questions regarding school life after some out-of-context conversation with their mother over Sorata's [[CloudcuckoolandersMinder relationship]] with Mashiro.
* ''Anime/{{Pokemon}}'':
** May's 8 year old brother Max. 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. He'd likely be less annoying if he were to show up again with his own Pokémon team.
** Clemont's younger sister, Bonnie, isn't apparently as annoying to the viewers so far, but she is to him, being a sort of reverse Brock. She thinks it's her duty to find Clemont a wife and asks every girl they meet to marry him. That said, she eventually grows out of it.
* ''Franchise/PrettyCure''
** ''Anime/FutariWaPrettyCure''
*** Ryouta Misumi is... Shingo Tsukino reincarnated or something, considering how he acts towards [[TheHeroine Nagisa]]. He even mirrors Shingo's feelings towards his sister's [[TheSmartGirl smartass friend]] Ami, with his own feelings towards [[TheLancer Hon]][[TheSmartGirl oka]]. That's said, despite being so annoying, it doesn't stop Nagisa from being an Embarrassingly Doting Big Sister to him or to go full KnightTemplarBigSister.
*** The next season features Pollun's younger sister Lullun who is even more annoying than Pollun himself. When she is introduced, she takes almost all of Pollun's annoying attitude.
** This is inverted with [[TheHeroine Saki's]] little sister Minori in ''Anime/FutariWaPrettyCureSplashStar''. Probably to prove that Saki is not just an {{Expy}} to Nagisa, Saki is the CoolBigSis who loves her cute little sister and doesn't mind to share her bedroom with her. Minori can be whiny, but she's not annoying and she's definitely an innocent girl. Her innocence even affects [[DarkMagicalGirl Kaoru]] [[EmotionlessGirl Kiryuu]].
** And [[TheLancer Rin Natsuki's]] siblings Yuu and Ai in ''Anime/YesPrecure5'' are Ryouta in stereo as HalfIdenticalTwins.
** ''Anime/HeartcatchPrettyCure''
*** Averted twice: first, [[TheLancer Erika]] is a main character, second, she does not act as an annoying younger sibling, she acts as an ''annoyed'' younger sibling to her older sister Momoka.
*** [[spoiler:[[TheDragon Dark Precure]] is TheRival and archnemesis to [[TheSmartGirl Yuri]] and turns out to be her artificial younger sister. That makes her a very tragic example, as Yuri learns the truth when Dark Precure is dying after their death battle.]]
** In ''Anime/SuitePrettyCure'', [[TheLancer Kanade]] [[TheSmartGirl Minamino's]] brother Souta often acts as an annoying younger sibling, but he is a much milder example than Ryouta. Kanade's best [[TheHeroine Hibiki]] and Souta's friend [[TheChick Ako]] [[TagalongKid Shirabe]] sympathize with him and they ''know'' his annoying character. But Kanade is a little bit too blind to notice his nice side.
** ''Anime/SmilePrettyCure''
*** [[TheBigGirl Nao]] [[CoolBigSis Midorikawa]] has ''five'' of them. Three brothers and two sisters. Though, Nao doesn't consider them as annoying and loves playing with them. [[TheHeroine Miyuki]] and [[TeamPet Candy]] however, have a hard time with them.
*** [[spoiler:Nao gets a ''sixth'' newborn sibling in episode 42. A girl. Probably, she will become annoying, too.]]
*** [[TheLancer Akane]] has a snarky younger brother called Genki. However, he is a mild example and Akane doesn't get really annoyed of him.
* Pictured above is Shingo Tsukino from ''Anime/SailorMoon''; he was actually quite tolerable and likable, but like many other extras, he vanished over the show's run. The AnnoyingYoungerSibling 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 being her KidFromTheFuture), whose actual involvement in the plot (so much so that she got her own season) made her a little too annoying.
* In ''Manga/ServantXService'', Taishi sees his younger sister Touko as this. However, Touko is just ''very'' Type-A {{Tsundere}} about her BigBrotherWorship.
* Spritle in ''Anime/SpeedRacer''. Speed was this to Rex in the ''Movie/SpeedRacer''.
* In ''Anime/{{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.
* Yuuki from ''Anime/{{Tokyo Magnitude 8}}'' is an odd case in that he isn't actually annoying. He is a pleasant, optimistic kid but that same fact annoys his moody teenage sister. She doesn't like how optimistic he is, even during an earthquake disaster.
* Bud Hanson from ''Anime/TransformersCybertron'' tends to get on his older brother Coby's nerves from time to time.

[[folder:Comic Books]]
* From Franchise/{{Batman}}, Tim Drake sees Damian Wayne as this. At one point when he tries to keep Damian out of a computer file the password he sets is [[CousinOliver cousinoliver]].
* ''ComicBook/CharlesSoulesDaredevil'' has Blindspot's sister, Hannah. Blindspot works a crappy job for crappy pay, barely has any time to sleep, and the two are illegal Chinese immigrants. Hannah goes out clubbing at random times, comes home late and wakes Blindspot up, and eats food he needs for work. Worse still, she ''expects'' this of him, because he's the older one.

[[folder:Fan Works]]
* ''FanFic/AGrowingAffection'': Hanabi becomes this to Hinata after the former's falling out with Naruto. Kakashi also describes Naruto as this.
* From ''Fanfic/HighlyQuestionableDecisions'', we have Ryuuko and, to a lesser extent, Nui being this to Satsuki.
* Victoria's backstory in ''[[Fanfic/TwiceUponAnAge All This Sh*t is Twice as Weird]]'' indicates that her older brother sees her as this. Whether it's justified is uncertain; the only reason given is that he got tired of her beating him in the practice yard so he avoids her as much as possible. She very occasionally invokes the trope on purpose with her [[LikeBrotherAndSister best friend]], just to tease him.
* Lana's younger sisters, Sarah and Harper, are implied to be this in ''Fanfic/PokemonResetBloodlines'', since she wouldn't be against someone calling them "fanged little monsters".

[[folder:Films -- Animated]]
* Dash of ''WesternAnimation/TheIncredibles'' fame, at least from Vi's point of view.
--> '''Dash:''' She'd eat if we were having "Tony-loaf."\\
'''Vi:''' ''THAT'S IT!'' ''[launches herself at Dash]''
* In ''WesternAnimation/SongOfTheSea'', Ben associates his little sister Saoirse coming with [[DeathByChildbirth his mother leaving]], which causes his negative attitude towards her. Her birthday is on the anniversary of their mother's death literally overnight, his mother disappears and in her place is a little sister. He then deals with his grief by bottling it up and taking it out on Saoirse.
* ''Disney/{{Brave}}'' gives Princess Merida ''three'' of these - the triplets Harris, Hubert, and Hamish. They're constantly creating mischief. However, when their big sister needs them, they do step up to the plate.

[[folder:Films -- Live Action]]
* Despite the fact they are adults, Tom Chamberlainn is played this way in ''Film/{{Gettysburg}}'' for his brother Joshua [[LastNameBasis "Don't Call Me Lawrence"]] Chamberlain. Historical records say he was probably quite different in RealLife. Joshua Lawrence Chamberlain DID call him "the little rogue" when Tom was younger, though.
* Mikey (and his friends) is this to Brand in ''Film/TheGoonies''. 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 Andy's FirstKiss from Brand. A bit of a subversion as Mikey is the protagonist.
* In ''Film/JurassicWorld'', Charlie the ''Velociraptor'' is constantly whacking her sisters with her tail. Poor Echo gets three solid whacks within minutes of their introduction.
* ''Film/ThorTheDarkWorld'': Loki knows how to get under Thor's skin, irritating the heck out of his brother with his shapeshifting pranks and his snarky comments about Thor's piloting skills during their escape from Asgard.
* ''Film/XMenFilmSeries''
** ''Film/XMenFirstClass'': Raven is jealous of Amy, a woman with whom her foster brother Charles is flirting, so she activates her shape-shifting skill to pretend to have heterochromia. Raven knows that Charles is terrified at the prospect of his younger sister being outed as a superpowered mutant, so it forces him to abruptly end his conversation with Amy. As the siblings are walking away from the pub, Charles is exasperated at Raven for ruining his potential date.
** ''Film/XMenApocalypse'': Alex Summers either rolls his eyes or ignores his younger brother Scott whenever the latter complains or is impolite.

* ''Literature/TheBabySittersClub'':
** David Michael and Karen, for Kristy. It's worth noting that Karen annoys the readers more than Kristy Kristy and Karen are just different enough to get along and just far apart enough in age that their similarities (namely, being bossy and stubborn) don't come into conflict, since Karen hero-worships her stepsister. It also helps that they only live together half the time, at most.
** Dawn's brother Jeff sometimes qualifies as this, DependingOnTheWriter.
** ''All seven'' of Mallory's siblings qualify, at least once in a while. The triplets are arguably the most guilty of the trope, but even Vanessa - easily the least annoying - has her moments too.
* Lucy is David's AnnoyingYoungerSibling from ''[[Literature/{{Dragons}} The Last Dragon Chronicles]]''. Although not biologically related [[spoiler: not in one of the universes, anyway...]], she pesters him into helping her, corners him into listening to her and never gives him a moment of quiet. This all ties into them forming their IntergenerationalFriendship as a result.
* ''Literature/HenryHuggins'' introduces Ramona, the annoying little sister of Henry's pal Beezus. Beezus often has to watch Ramona while hanging out with Henry, causing her to be this trope not only to Beezus herself but also to Henry (who is an only child).
** And then, ironically, Ramona got ''[[Literature/RamonaQuimby her own series]]'' and Beezus was relegated to periodic appearances.
** In her own series, Howie's sister, Willa Jean, [[{{Irony}} is to her what she used to be to Henry]].
* Literature/{{Fudge}}, in ''Tales of a Fourth-Grade Nothing'' and its sequels by Creator/JudyBlume, makes more trouble than any character in the series, but almost never gets told off for it. Not even after he ''eats Peter's turtle on purpose''. Peter is the narrative character, so his perspective ''is'' a little biased... but not by much. Tootsie, the boys' baby sister, generally averts the trope if only because she's too small to be much of a nuisance.
* A picture book by Blume called ''The Pain and the Great One'' talks about this trope and its opposite from either's perspective. The older girl resents her younger brother for irritating her and not having as many responsibilities. The younger brother resents his older sister because she can do more and shows it off. Both consider themselves TheUnfavorite.
* Dairine of the ''Literature/YoungWizards'' 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 [[spoiler:and eventually even a more powerful wizard]].
* Tiffany Aching's younger brother, Wentworth, in ''Discworld/TheWeeFreeMen'' by Terry Pratchett. He gets better as he grows older, though.
* ''Literature/PercyJacksonAndTheOlympians''
** Several Greek gods act like this. Most notably, Apollo is this to Artemis, although she can't really call him her annoying ''younger'' brother, since they're twins .[[note]]Certain versions of the original myth indicate she is older -- by all of a few minutes, since after she was born she immediately helped with Apollo's delivery![[/note]]
** Nico di Angelo has this vibe early in ''The Titan's Curse''. He's clingy, asks lots of questions, and is obsessed with the Mythomagic card game. Big sister Bianca loves him, but as they're orphans, she's tired of being joined at the hip with him and jumps at the chance to be an immortal Hunter of Artemis once she's assured that he'll be taken care of at Camp Half-Blood. [[spoiler:Then she dies. Nico doesn't take it well.]]
** Sadie Kane of Literature/TheKaneChronicles (by the same author) has to be one of the most annoying younger siblings of all time - and the most dangerous.
* Manny of ''Literature/DiaryOfAWimpyKid'' 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 ''Literature/TheSilmarillion'' 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.
* Nearly every ''Literature/{{Goosebumps}}'' protagonist has one. Special mention to Tara from "The Cuckoo Clock of Doom" [[spoiler:who is accidentally ''[[RetGone erased from history]]'' by her brother's time-traveling. He realizes that he could theoretically go back and fix things, and maybe he will. Maybe.]]
* ''Literature/The39Clues'' has the (admittedly VERY awesome) Dan Cahill. Even though he can be annoying sometimes, his talents, especially his PhotographicMemory can come in handy. [[SpoiledBrat Natalie]] [[TheRival Kabra]] is one to her brother, Ian. While he definitely [[BigBrotherInstinct does care for her]], it is said in one of the books that he doesn't "even like Natalie."
* ''Literature/HarryPotter'': even though Fred and George are older than Ron, they still fill this trope for him. They ''are'' the {{Class Clown}}s 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, and Percy is also seen as this by his two older brothers. Ginny is a more direct example for Ron, though she's more likely to bring out his BigBrotherInstinct than to actually annoy him very much.
* ''Literature/ArtemisFowl''
** During the events of ''The Lost Colony'', Artemis 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 [[CuteBruiser Juliet]] to Butler in the first book, before she TookALevelInBadass.
** Captain (later [[MajorlyAwesome Major]], later [[FourStarBadass Commander]]) Trouble Kelp is the LEP's "Golden Boy" [[HeroOfAnotherStory for a reason.]] Corporal ''Grub'' Kelp is named "Grub" [[CowardlySidekick for a reason]]. The latter may involve filing complaints over [[MinorInjuryOverreaction hangnails]] and saying [[IWantMyMommy "Mommy said"]] on the battlefield.
* Sophie is the annoying younger sister of the title character in ''Literature/PlanetTad'', a regular feature in ''Magazine/{{MAD}}'', later released as a book.
* In ''Literature/TheSavannahReidMysteries'', all of Savannah's younger siblings except Waycross and Alma.
* ''Literature/GalaxyOfFear'''s protagonists are a thirteen-year-old girl and her twelve-year-old brother. Mostly they get along well, but when Tash is approaching fourteen and trying to be grown up, she finds Zak amazingly annoying.
* The three youngest Bennet sisters in ''Literature/PrideAndPrejudice''. Mary is a KnowNothingKnowItAll; Kitty is an easily led [[TheDitz ditz]]; and Lydia, the youngest and most annoying of all, is a shallow, air-headed brat with no manners and no concern for anyone else. (It doesn't help that she's her mother's favorite and gets away with a lot.)
* Poor Anastasia in ''Literature/PrinceCharming'' has to put up with her spoiled younger brother, Prince Dmitriv. He expects her to rescue him from all the simpering young ladies he has caused to fall in love with him. And then he expects her help when ''he'' falls in love.
* Averted in ''Literature/SummersAtCastleAuburn''. Corie has many traits that her proper older sister could find very irritating, such as being a curious, cheeky, nosy tomboy; but [[OneeSama Elisandra]] not only doesn't mind, she loves Corie specifically because of those things.
* In ''Literature/HeartInHand'', although it's made clear that they do have a good relationship with each other, Darryl's sister Brynn embarrasses and teases him, often teaming up with his teammates or Alex.
* In ''Literature/TheBigWave'', Kino's younger sister Setsu plays pranks and hides his things.
* Thomas to Joshua Lawrence Chamberlain in ''Literature/GodsAndGenerals'' and ''Literature/TheKillerAngels'', mildly. Mainly because he keeps addressing his brother the colonel by name instead of rank or "sir."
* In Jeramey Kraatz's ''Literature/TheCloakSociety'', Misty has her moments of this, especially when she insists that being ten and having less training will not keep her out of the fight.
* ''Literature/{{TACK}}'': Holly, Toria's little sister, who taunts Toria by calling her "Vicki", teasing her big sister that she and Will are boyfriend and girlfriend, and using her cuteness to get what she wants.
* ''Literature/SenseAndSensibility'': Marianne to Elinor, although Elinor has much more affection for Marianne than the trope implies. Their youngest sister, Margaret, is rarely annoying -- and indeed has so little presence in the story that her existence is often forgotten; she does, however, have one moment of fulfilling the trope. When Mrs. Jennings asks for information about Elinor's LoveInterest, Margaret innocently obliges.

[[folder:Live-Action TV]]
* ''Series/ImTelling'', a kiddie variant of ''Series/TheNewlywedGame'' that aired on [=NBC=]'s Saturday morning schedule in 1987-1988; this show ''lived'' on pairing older 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, [[GenderBlenderName he was a "he"]]) was the host of this pale clone of the real thing. Audiences didn't care for it and it didn't survive past one season. The child contestants (all ages 8-16, and stereotypical even by late-1980s standards) ''had'' to be embarrassed when it showed up in reruns on the Family Channel from 1994-1996.
* ''Series/LittleHouseOnThePrairie'' has Carrie Ingalls, the third daughter of Charles and Caroline Ingalls, and in many episodes a thorn in the sides of ''both'' Mary and Laura.[[note]]This was partly due to her being a CompositeCharacter; there were actually four Ingalls daughters, as seen in the books, but youngest sister Grace never appeared on the show and was sort of pushed into being part of Carrie's personality.[[/note]] Even though Carrie didn't get the spotlight very often, there were two specific episodes where the spotlight ''shone'' 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 mine shaft.
** 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.
* ''Series/TheBradyBunch'': 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., witnessing the mailman behaving inappropriately with one of her sisters -- but suppresses it for fear of being punished by her parents, were considered for this episode. This episode was filmed in the fall of 1970 and the network likely would have been nervous about airing such a plotline in a family-friendly time spot, hence the seemingly awkward subplot using the by-now nearly forgotten Tiger (in his last appearance, after making sporadic 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 because 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-totter record.
** "The Big Bet," a 1972 episode where Bobby annoys Greg at every turn. To get him to go away, Greg says in jest that he could do twice as many pull ups as Bobby, not counting on Bobby demanding that he put up or shut up. Bobby eventually backs Greg into a corner by demanding a bet the loser does whatever the winner says. When Greg loses, Bobby decides to tag along on Greg's big date with Rachel. In addition to acting as a cock block, Bobby annoys Greg (and Rachel) at every turn by making stupid demands and comments at a drive-in movie. One of those demands includes putting up the top of the convertible ("It might rain," declares Bobby) ... and the annoying tyke tearing a hole in the roof when he forgets to put an umbrella away.
** "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 tries to carry 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 from a date, refusing to let him explain that Greg had waited with his date at her home until her parents returned; or Alice -- a non-sibling, but still -- setting out aerosol cans with the rest of the garbage, not letting her explain that the waste collector had a new policy on how trash should be sorted.) Mike and Carol eventually find out and counsel Bobby, telling him in no uncertain terms that he had better knock off his behavior.
** "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 (unbeknownst 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!"
* ''Series/KamenRiderExAid'': [[TastesLikeDiabetes Nico Saiba]] is ''very'' annoying adoptive sister of [[DoctorJerk Taiga Hanaya]]. She [[DidYouJustFlipOffCthulhu doesn't]] have exactly well seated sense of self preservation, [[NoSenseOfPersonalSpace naggs]] on him and messes up his attempts to be a brooding tough guy. This is partially because she is a [[ManChild brat]] and a {{Troll}}. The other part is down to the fact that she is trying to dot over him, but he [[DontYouDarePityMe doesn't take it]] exactly well pressing her into doing so in a way that involves plenty of [[SugarWiki/FunnyMoments hard knocks]] and ''[[SugarWiki/HeartwarmingMoments awws]]''.
* Michelle from ''Series/FullHouse''. Stephanie is also this to D.J. at times.
* Creator/DisneyChannel loves this trope, so much so that almost all of its live action shows have at least one. Examples:
** Matt from ''Series/LizzieMcGuire'', who to some is actually much cooler than Lizzie. But to be fair, like most of Disney Channel tween show protagonists, [[CoolLoser she was designed to be a loser]].
** Louis Stevens in ''Series/EvenStevens'' is the youngest of the family who serves as the BlackSheep and more than often causes trouble for the rest of the family, especially Ren.
** Then there's Raven's brother Cory in ''Series/ThatsSoRaven'', who would often devise ways to scam others (including his own family) out of their money, being the money-hungry maniac he is.
** Jackson from ''Series/HannahMontana'' functions as an Annoying Younger Sibling; although technically he's older than Miley, much is made of him looking and acting younger.
%%** Flynn from ''Series/ShakeItUp'', due to being Matt's {{Expy}}, and being less annoying.
* The little sister of the titular ''Series/DrakeAndJosh'' isn't just annoying... she's ''[[VillainWithGoodPublicity evil]]''.
* It sort of is and isn't subverted in ''Series/MyParentsAreAliens''. 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; although he's their foster father, he's able to morph into any one of the siblings at will (though usually only does it 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 ''Series/{{Heroes}}''.
* Nickelodeon's ''Series/MyBrotherAndMe'' 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.
%%* ''Series/BuffyTheVampireSlayer'': Anya's relationship with Willow is meant to be like this; despite being thousands of years older than Willow, she's more naive and immature, which Willow is frequently annoyed by.
* From ''Series/LifeWithDerek'', we have Marti and Edwin. Although, to be fair, all five get their fair share of "annoying" at times... including the older ones.
* ''Series/YoungDracula''
** 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); 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 ''Series/MarriedWithChildren''.
* Although both characters are adults, [[RoyalBrat Juan]] is definitely this to [[MagnificentBastard Cesare]] in ''Series/TheBorgias''. 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 [[SinisterMinister Cardinal]]. But on top of that, [[SpoiledBrat Juan's]] [[TheDitz really]], ''[[DrunkWithPower really]]'' [[{{Troll}} aggravating]]. Hardly surprising that it ends with [[spoiler: a full-scale CainAndAbel situation, with Cesare murdering Juan and dumping his corpse in the river.]]
* ''Series/GameOfThrones'':
** According to his 'confession' before the court at the Vale of Arryn, Tyrion Lannister was this in his younger days. He stole clothes, put goat shit in his uncle's boots and milked his eel into a pot of stew.
-->"When I was twelve, I [[ADateWithRosiePalms milked my eel]] into a pot of turtle stew. [[HurricaneOfEuphemisms I flogged the one-eyed snake, I skinned my sausage, I made the bald man cry!]] INTO THE TURTLE STEW! Which I do believe my sister ate! Or at least, I ''hope'' she did!"
** Arya Stark threw food at Sansa at a feast, filled her mattress with sheep dung whenever she was angry with her (which happened to be all the time), and constantly embarrassed her by acting 'unladylike.'
** Played with with Arya and Gendry, who becomes something of a substitute brother and he looks out for her, and she obliges by constantly exasperating him. That said, she also has his back and even persuades the Gold Cloaks that he's already been killed so they can stop hunting him down.
--> '''Gendry:''' How can someone so small be such a huge pain in my arse?
* On ''Series/TheVampireDiaries'', most of the Mikaelson siblings are this. [[ItsAllAboutMe Klaus]] constantly upsets and aggravates his [[TheDutifulSon big brother Elijah]], while [[SpoiledBrat Rebekah]] annoys Klaus, and [[AxCrazy Kol]] gets on absolutely everyone's nerves.
* Jerome seems to feel this way about Poppy in the second season of ''Series/HouseOfAnubis''. She has his manipulative skills, and knows how to use them, which causes a bit of riff between them, at least until their relationship with their father brings them closer as well.
* ''Series/KatieMorag'': Katie Morag sees Liam as this sometimes, to the point that she even makes a wish on a standing stone for him to be less annoying. By the end of that episode, she [[AnAesop learns that little brothers aren't so bad after all]].
* Played with in ''Series/NickyRickyDickyAndDawn''. Dawn, who is the oldest (by four seconds as she brags), finds her brothers annoying at times.
-->Dawn: I learned a lot in those four seconds.
* ''Series/MaxAndShred'': Not as bad as on other shows, but Alvin can be annoying to Abby. He especially was on her ninth birthday.
* ''Series/HenryDanger'' has Piper, Henry's younger sister who is very high strung and impatient, especially when she doesn't get her own way.
* ''Series/ClarissaExplainsItAll'' has Ferguson, with whom Clarissa has such an antagonistic relationship that they have pictures of one another on their bedroom doors - with "no" symbols superimposed on top.
* A regular character in ''[[Series/HarryEnfieldAndChums Harry Enfield's Television Programme]]'' was Little Brother, a.k.a. Kevin, a hyperactive attention-seeking pre-teen who was constantly irritating and getting under the feet of his older brother and parents. In the first episode of the re-titled ''Harry Enfield And Chums'', at midnight on his thirteenth birthday, he abruptly transformed into his much worse (and much better-remembered) incarnation: Kevin the Teenager.

[[folder:Newspaper Comics]]
%%* ''ComicStrip/{{Curtis}}'' has Barry, who benefits from ParentalFavoritism.
%%* Hammie jumps in and out of this in ''ComicStrip/BabyBlues''.
* ''ComicStrip/{{Peanuts}}'': Lucy and her little brother, Linus, regard each other as annoyances. For Lucy, it's because Linus always embarrasses her by dragging his security blanket everywhere and constantly sucking his thumb. By comparison, [[BigBrotherBully he sees her as a bully]], who either threatens to beat him up or tries to take his blanket away (depending on her mood).
** ZigZagged in the case of Sally, Charlie Brown's little sister. While she ''is'' obnoxious, brash, and demanding, and oftentimes embarrassing, Charlie Brown still adores her, even if his aggravation slips through now and then. He still takes it upon himself to help Sally with her homework and walk her to and from school, no matter how annoying she can act.

[[folder:Stand-Up Comedy]]
* Creator/BillCosby has a routine called "My Brother Russell," revolving around a terrible night trying to sleep in the same bed as his youngest sibling. Cosby actually had several of these, including one where Russell would tell his parents Bill had set him on fire.
* Comedian and TV presenter Russell Howard gets a lot of his on-stage mileage out of his younger brother Daniel and his antics.

[[folder:Video Games]]
* Inverted in ''VideoGame/ManaKhemia2FallOfAlchemy'' with {{Cloudcuckoolander}} Et being the source of irritation for her CloserToEarth younger brother Enna.
%%How is he annoying?* In VideoGame/NightTrap, there is Danny, Lisa's little brother.
* Blanc from ''{{VideoGame/Neptunia}}'' has to deal with two annoying younger siblings, Ram and Rom. Ram is an extroverted, mischievous little brat; Rom is a timid and shy girl, but she helps Ram pull her pranks on Blanc.
* ''VideoGame/SoulCalibur III'': Though they aren't related, [[{{Tomboy}} Seong]] [[SexyMentor Mina]] regards her student, [[HotBlooded Yun]] [[IdiotHero Seong]], as a younger sibling. But he's pigheaded and won't listen to reason, despite her warnings concerning [[ArtifactOfDoom Soul Edge.]] So she takes upon herself to [[ToughLove knock some sense into him]] and [[http://www.youtube.com/watch?v=5MzaVxopQEw drag him back to her father's dojo.]]
* Seen in ''VideoGame/DragonAgeOrigins'' in the Dwarf Noble origin. The {{player character}}'s younger brother Bhelen isn't just annoying, he's ''murderous'' - but until that happens, he merely comes across as this trope. Their older brother, Trian, treats the player character as being this (out of jealousy); it's up to the player whether or not it's justified. The other two origins which give the player character older siblings (Dwarf Commoner and Human Noble) both avert the trope, as their older siblings care for them greatly no matter how the player chooses to have the character behave.
* ''VideoGame/DragonAgeII'' gives the protagonist Hawke a pair of younger twin siblings, Carver and Bethany. Only one survives the prologue. If it's Bethany, the game largely averts the trope; Carver plays it straight, as he acts out due to feeling like he's stuck in his older sibling's shadow.
* ''VideoGame/DragonAgeInquisition'' reveals that former Templar Cullen was sometimes this in his younger days for his big sister Mia, though he stresses that she was every bit as annoying right back. Now in adulthood, the main thing he does that annoys her is to not write as often as she feels he should (and, if he's romanced, to not give sufficient details when he does write). When he does speak of her and their other siblings, it's usually with great fondness.

[[folder:Visual Novels]]
* Colin in ''VisualNovel/LovelyLittleThieves'' is a InsufferableGenius with a huge ego and a bratty attitude, which rubs every member of the group the wrong way, except, quite ironically, his older sister, Danielle, who is one of the few people he actually gets along well with.

[[folder:Web Animation]]
* In ''WebAnimation/GEOWeasel'', Nar finds his younger brother Mitri annoying because of his [[TheOmnipresent ability to be anywhere at any time]].
** However, [[InvertedTrope it goes both ways]], as Mitri finds Nar's [[TheDitz ditziness]] annoying enough to [[CurbstompBattle "own"]] him.[[/folder]]

[[folder:Web Comics]]
* Timulty in ''WebComic/OzyAndMillie'' is Avery's AnnoyingYoungerSibling, 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....
* ''Webcomic/TheCyantianChronicles'': 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.
* ''WebComic/EerieCuties'': Layla's kid sister, Nina, ranges from [[http://www.eeriecuties.com/strips-ec/all_scrawny embarrassing]], to infuriatingly thoughtless at times - with the worst instance being when she plotted to [[spoiler: [[http://www.eeriecuties.com/strips-ec/extra_honey steal Layla's body]], offered to let Blair feel her up, then used it to go on a date with Layla's boyfriend, Kade]] just because Layla [[DisproportionateRetribution poked fun at her.]]
* ''Webcomic/MagickChicks'': Tiffany is frequently irritated by her kid brother, Dusky:
** She doesn't approve of him participating in breastplate raids at her school, especially since the guys at Apollo treat it as a game [[http://www.magickchicks.com/strips-mc/some_poor_girl at the girls' expense.]]
** One of the bonus stories in the print edition of Vol.4 reveals he has a habit of walking in on her, during her morning workout - [[spoiler: which she does ''[[{{fanservice}} naked]]'']].
** Also lampshaded in a bonus story for ''Webcomic/EerieCuties'', where she brings him with her to the beach on a monster hunting expedition, though he keeps insisting there aren't any. And when [[spoiler: Tracy Milligan]] shows up, Tiffany tries to ignore her - except Dusky [[UnwantedAssistance fails to take]] [[http://www.eeriecuties.com/strips-ec/siren_brawl_-_pg_2_of_12 the hint.]]
%%* [[EnsembleDarkhorse Fan favourite]] Yuri Zahard to her adoptive sister Maschenny in ''Webcomic/TowerOfGod''. Probably stems from the fact that the two are very alike.
* Zoe's sister Min from ''Webcomic/SluggyFreelance''. She seems to be a pretty cool person most of the time, but becomes ultra-annoying when she goes into StalkerWithACrush mode (mainly focused on Riff).
* Julia Greenhilt, little sister to Roy from ''Webcomic/TheOrderOfTheStick'', is the bratty teenage version; she's 12 years his junior, but still manages to annoy him by being [[MouthyKid mouthy]], an AttentionWhore, and dressing in {{Stripperiffic}} clothes. Despite all this, it's clear they really do love each other.
* ''Webcomic/OrangeMarmalade'' 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 PetTheDog moment with him every once in a while. Every once in a long while.
%%* Angelika, in ''Webcomic/OurLittleAdventure'', though her older sister Julie can be [[LoveFreak quite]] [[ExpoSpeak annoying]] to some as well.
* In ''WebComic/ForestHill'', Paz's quiet nature and quick thinking tends drive his older brother crazy.
* ''Webcomic/FurryExperience'': Diana has a tendency to take things without asking, feeling her "special projects" justify it, which gets on her older brother Brian's nerves [[BrattyTeenageDaughter as well as their mother's]].

[[folder:Web Original]]
* Maybe half the main characters in the webfiction ''Literature/WhateleyUniverse'' have an AnnoyingYoungerSibling who ranges from "pretty normal but wishing he had a superpower too" ([[MarySue Chaka's]] little brother) through "bratty behavior that accidentally poisons the protagonist" ([[GodModeSue Tennyo's]] younger brother) all the way up to "calling out a heavily-armed squad of anti-mutant soldiers and sicking them on protagonist" ([[MarySue Lancer's]] younger brother).
* In the ''Roleplay/GlobalGuardiansPBEMUniverse'', former Guardian Bandit has an AnnoyingYoungerSibling 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 SecretIdentity.
* Subverted with WebVideo/TheNostalgiaCritic. While he ''is'' annoying, his big brother The Other Guy slaps him around and controls him for no reason other than for fun.

[[folder:Western Animation]]
* Haley in ''WesternAnimtion/AmericanDragonJakeLong''.
* D.W. in ''WesternAnimation/{{Arthur}}''. To his chagrin, all of Arthur's friends and just about everyone they meet take a liking to her.
* Carl in ''WesternAnimation/AsToldByGinger'' can sometimes be this to Ginger, particularly when his [[NightmareFetishist weird scientific experiments]] would get on Ginger's nerves.
* In ''WesternAnimation/AvatarTheLastAirbender'', Azula was this to Zuko when [[CainAndAbel she wasn't trying to kill him.]]
* Matt from ''WesternAnimation/BatmanBeyond'' 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. Terry is also secretly pleased by the fact that Matt [[LovesMyAlterEgo is a big fan of the new Batman]].
* WesternAnimation/{{Beetlejuice}} has a younger brother, Donny, who is completely unlike him in almost every respect. Clean, honest, friendly, and well-liked by everybody (at least at first), Donny drives BJ crazy. He adores his big brother, however, and the most annoying thing about him is that he tries very hard to push for them to have a closer relationship.
* The titular 4-year-old in ''WesternAnimation/BobbysWorld'' can come across as this at times to his brother and sister, mostly to [[BigBrotherBully his brother]].
* In ''WesternAnimation/CodeLyoko'', Hiroki Ishiyama to his sister Yumi. Not just a BrattyHalfPint, but also a HonestJohn in training.
* ''WesternAnimation/CodenameKidsNextDoor''
** 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 BoringFailureHero.
** Also Numbuh 3's younger sister Mushi.
** And Numbuh 5 herself is this to her teenage sister, Cree. Being as Cree is a teen and thus a sworn enemy of the Kids Next Door, this is an example of TheGloriousWarOfSisterlyRivalry taken UpToEleven.
* An interesting case in that the main character of ''WesternAnimation/DannyPhantom'' used this exact trope to get his sister Jazz to embrace her childhood (she thinks she is an adult in a teen's body), and thus get her to see a ghost [[ByTheEyesOfTheBlind only visible to children]]. He will 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.
* [[LovableAlphaBitch Quinn]] from ''WesternAnimtion/{{Daria}}''.
** Also [[AlphaBitch Sandi]]'s younger brothers, both of whom have a PrecociousCrush on Quinn. Also [[SpoiledSweet Brittany]]'s younger brother [[TroublingUnchildlikeBehavior Brian]], though he seems to spend more time antagonizing their father.
* Inverted in ''WesternAnimation/DextersLaboratory'', where the annoying Dee Dee is actually Dexter's ''older'' sister.
* Ed's little sister Sarah from ''WesternAnimation/EdEddNEddy''. She isn't just annoying but also a bossy, whiny, psychotic, ill-tempered SpoiledBrat.
* Chris to Meg in ''WesternAnimation/FamilyGuy''. Stewie can be this to both of them, 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.
* Pistol Pete, younger sister of PJ in ''WesternAnimation/GoofTroop'', both due to [[SiblingYinYang having radically different conduct and temperaments]] and their father's ParentalFavoritism - which leads to her being allowed to take complete advantage of him.
* Corey Riffin is considered to be this to his older biological sister Trina Riffin in ''WesternAnimation/{{Grojband}}'', as she and Corey usually get involved in a sibling rivalry, in which he gets the last laugh.
* Robbie Hobbie to Holly at times in ''WesternAnimation/HollyHobbieAndFriends'', though his subplots often involve him having entirely separate adventures with his best friend Kyle.
* ''WesternAnimation/KaBlam'': In the ''Life With Loopy'' shorts, Loopy is sometimes this to her older brother, Larry. Otherwise, they get along pretty well.
* Brianna is this to the titular character of ''WesternAnimation/KickButtowski'', while their older brother Brad seems to regard Kick as this.
* LesSisters: Seven-year-old Marine enjoys annoying her teenaged sister Wendy for fun.
* Lola is this to Lincoln in ''WesternAnimation/TheLoudHouse''. Then again she is an {{Expy}} of Brianna from the above ''WesternAnimation/KickButtowski''.
* Jim and Tim (the "twin dweebs," or "tweebs") in ''WesternAnimation/KimPossible''. They're this trope squared, which is why they're called "The Tweebs." They get better as they grow older.
* ''Literature/MaxAndRuby'' 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.
* John, Chris' brother, in ''WesternAnimation/MonsterBusterClub''. 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.)
* Sweetie Belle and Apple Bloom in ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' 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 [[DisasterDominoes 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.
** Fluttershy's younger brother Zephyr Breeze, introduced in [[Recap/MyLittlePonyFriendshipIsMagicS6E12FlutterBrutter "Flutter Brutter"]], is [[LazyBum lazy]], {{Narcissist}}ic, [[AbhorrentAdmirer constantly flirts with Rainbow Dash]], and in general is one of the few ponies able to annoy [[AllLovingHero Fluttershy]].
* In ''WesternAnimation/PhineasAndFerb'', Phineas (and to a lesser extent, Ferb) were originally been intended 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 CharacterisationMarchesOn, and they're much more likely to want to help Candace out than annoy her.
* T.J. (the series protagonist) can be this to his older sister, Becky, in ''WesternAnimation/{{Recess}}''.
* ''WesternAnimation/SpongebobSquarepants'' is this to Squidward. He isn't actually Squidward's brother, but dialogue frequently indicates that he sees their relationship as this ("We're like brothers, only closer.")
* Daggett Beaver of ''WesternAnimtion/TheAngryBeavers'', who's technically the younger sibling by several seconds. He means well, but he's impressionable and incredibly high-strung.
* Ray Ray from ''WesternAnimtion/TheLifeAndTimesOfJuniperLee'' is everything a little brother shouldn't be.
* In ''WesternAnimation/TheWildThornberrys'', this is how Debbie Thornberry sees Eliza.
* Christopher (to Irma) and Lillian (to Cornelia) in ''WesternAnimation/{{WITCH}}''. As it turns out, Lillian is actually kind of a sweetie, and only acts the way she does half the time because [[JerkWithAHeartOfGold Cornelia is mean to her]].
* '' WesternAnimtion/WordGirl'''s younger brother, TJ.
* ''WesternAnimation/{{Caillou}}'': Rosie bugs Caillou sometimes, though it [[DependingOnTheWriter depends on the writer.]] [[ExactlyWhatItSaysOnTheTin "Rosie Bothers Caillou"]] makes it the whole point of the episode.

[[folder: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 NiceGuy; sometimes that's more important, though sometimes not so much.
** And Napoleon himself treated his younger siblings (especially the youngest, Caroline and Jérôme) as this, even more so when they convinced themselves that they had as much of a right as him to actually rule the puppet kingdoms he gave them. Given that Louis was a [[IllGirl rheumatic, paranoid mess]], Caroline was [[AmbitionIsEvil ambitious and manipulative]], and Jérôme earned the nickname "König Lustig" because he preferred to spend public funds and have numerous affairs, his annoyance was perhaps not entirely unjustified.
* Billy Carter, the alcoholic, slightly racist brother of President UsefulNotes/JimmyCarter, seemed born to become tabloid-bait.
** Same with Roger Clinton, President UsefulNotes/BillClinton's cocaine-addled LoungeLizard of a half-brother.
* And you probably once fit into this trope too, if you were the youngest in your family.
** 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 [[http://en.wikipedia.org/wiki/Gemma_Galgani 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 to profit from Gemma's reputation (and apparently, her relics).
