->"I always wanted a brother. Hey!-- (gets a face full of paint) Instead, I got stuck with two sisters."
-->-- ''WesternAnimation/{{Arthur}}'', from "The Perfect Brother"

The outnumbered sibling often occurs when a character (usually the protagonist) is the only girl or boy in their (usually large) family. This can result in the character hoping and praying for a sibling of their gender, ParentalFavoritism either for or against the character, and the character feeling either superior or inferior to the rest. More often than not the outnumbered sibling will either be the oldest or the youngest. If they're in the middle out of three, it's one of the more common aversions to MiddleChildSyndrome since they stand out by virtue of their gender.

Subtrope of MassiveNumberedSiblings. See also TheSmurfettePrinciple and IHaveBrothers. Often appears in a character's BackStory even if it isn't depicted in the plot.

''Highly'' expect AnnoyingYoungerSibling and/or BigBrotherBully to come into play and for creators to throw in a MissingMom (for a girl) or a DisappearedDad (for a boy) for added effect. Extreme cases may include a PromotionToParent as well.


[[folder:Anime and Manga]]
* ''LightNovel/SisterPrincess''. An orphan named Wataru Minakami discovers that he has 13 sisters, one of whom is [[spoiler:TheMole, and not actually one of his sisters]].
* Quatre Raberba Winner of ''[[Anime/MobileSuitGundamWing Gundam Wing]]'' is the youngest child of his family and has ''twenty-nine sisters''. The catch is that [[spoiler:all of his sisters are [[DesignerBabies test-tubes babies]] due to difficulties with childbirth in space among early space colonists; Quatre was the only child born naturally, although [[DeathByChildbirth his mother died during childbirth]] and the fact that he wasn't artificially reproduced was kept secret from him.]] However, Quatre is shown to dearly love his sisters and it is [[spoiler:the near-death of his favorite older sister Iria (along with the death of his father) [[BewareTheNiceOnes which drives poor Quatre over the edge.]]]]
* ''Manga/IceRevolution'' Misaki became an extreme tomboy growing up as the only girl in a family of extremely macho martial artists. However, she does not come into conflict with any of them until she decides she wants to take up the "girly" sport of figure skating. Even then it serves more as backstory than a plot point.
* ''Manga/{{Maomarimo}}'': Mao has three older sisters: Sakuya, Kaguya, and Ako, his more outgoing elder twin. Ironically, he demonstrates more stereotypically feminine traits (particularly {{Dojikko}}, ShrinkingViolet, and FeminineWomenCanCook) than the three of them put together.
* ''Manga/CardCaptorSakura'': Syaoran has four older sisters. All of whom are obsessed with cute things. He does not seem thrilled about it.
* ''Manga/{{Otomen}}'': The author of [[ShowWithinAShow Lovetic]], believed by all readers to be a girl, is [[MoustacheDePlume a boy]] [[IHaveBrothers with several little sisters]]. [[MassiveNumberedSiblings Ten to be exact]].
* Alto Krauetta of ''Franchise/LyricalNanoha'', whose family comprised three brothers. The lack of any female influence in her early life led to her thinking that she was a boy [[NoodleIncident until an incident involving the school toilet when she was seven]].
* Nagisa from ''Anime/{{Free}}'' has three older sisters who were very fond of [[DraggedIntoDrag dressing him up]] when he was younger.
* ''Manga/{{Bleach}}'': Soifon was the youngest of six siblings, and the only girl. She was also the only successful sibling. All five of her brothers died quickly without amounting to much and she only remembers them with a feeling of shame at their failure. Her talent was recognised quickly; within seven years she was commanding the court guards and earned her great-grandmother's code-name "Soifon", before eventually becoming both a [[{{Samurai}} Gotei 13]] captain and Supreme Commander of the [[{{Ninja}} Secret Remote Squad]].

[[folder:Comic Books]]
* Hope O'Dare from ''ComicBook/{{Starman}}'' has four brothers. She and her brothers are all cops and it's mentioned that she is the one everyone is frightened of.
* ''ComicBook/{{Princeless}}'': Devin has seven sisters.
* In ''Franchise/TheSmurfs'' Papa Smurf has 100 sons but just one daughter, Smurfette. Later, the Smurfs create another sister called Sassette.
** In ''Film/TheSmurfs2'', Gargamel creates a sister for Smurfette in the form of Vexy.

[[folder:Film -- Animated]]
* Thumper from the film ''Disney/{{Bambi}}'' has five sisters, [[FridgeHorror which is reduced to four in the midquel]].
* PlayedWith in ''WesternAnimation/{{Brave}}:'' Princess Merida's the oldest child and only daughter of the royal family, with three younger brothers (who're also triplets). However, Merida gets along just fine with her brothers and the main conflict of the film comes from the fact that Merida's a {{Tomboy}} [[RebelliousPrincess being forced into a ladylike role]] by her mother.
* At the end of ''Disney/LadyAndTheTramp'' the title dog couple become the parents of three daughters (who all look identical to their mother) and a fourth male puppy named {{Scamp}} (who looks identical to their father).
** The exact same is true with [[{{Dogfaces}} Doppler]] and [[CatGirl Amelia's]] children from ''Disney/TreasurePlanet''.
* In the animated adaptation of ''WesternAnimatiion/HortonHearsAWho'', Jojo's the only son in a family with ''96 daughters''. No wonder he feels a little left-out.

[[folder:Fan Works]]
* In ''Fanfic/FrozenHearts'', [[spoiler:Hans not only had thirteen brothers]], but also a sibling of the opposite gender. [[WalkingSpoiler Said sibling's existence is something of a spoiler]], since the person in question is dead as of the start of the story.

[[folder:Film - Live-Action]]
* ''Film/TheLegendOfFrenchieKing'': Maria has four brothers who she bosses around. They, in turn, are men children and intimidated by her.
* A ''[[Film/TheLittleRascals Little Rascals]]'' short, ''Our Gang'', illustrates this trope with a hint of ValuesDissonance. Mickey is picked on by his two sisters and hopes that the baby his mother is pregnant with is a boy. Somebody tells him that [[UrbanLegend every fourth child in the world is born Chinese.]] He's upset by the idea of having a Chinese younger brother but eventually comes to accept it. Unfortunately from his point of view, his mother gives birth to another girl.
* Roberta from ''Film/NowAndThen'' had three older brothers and no sisters. The brothers are only briefly seen but it explains why she's such a tomboy.
* Adam Sandler's character in ''Film/PunchDrunkLove''.

* In ''Literature/ABrothersPrice'' Jerin (who does have brothers) is asked by his new friend Cullen how it is to have other men in the house. Cullen's father apparently died early, leaving him the only male in the whole family. Due to male GenderRarityValue, this is quite normal in the setting, a family with more than one boy is considered extremely lucky. The Whistler family's neighbours, the Brindles, have thirty daughters and one son, and other people think they should just stop trying for another son, as they soon won't be able to feed all their children anymore.
* In ''Literature/DragonBones'', Ciarra has two brothers, two male cousins, and no sisters or female cousins. This becomes even more extreme when Ward sort of adopts Oreg into the family, a distant relative, who [[Really700YearsOld seems to be seventeen.]] This is good for her in that she has three protective older brothers, but when she meets another young woman, Tisala, it becomes obvious that she enjoys the opportunity to talk to another girl very much. Despite Ciarra being a CuteMute, the two of them manage to talk to each other about how enervating Ward's behaviour can be, as Tisala is one of the few people who understand Ciarra's sign language intuitively.
* Ginny Weasley of the ''Literature/HarryPotter'' series takes this to a bit of an extreme. Not only is she the only girl in a family of seven children, she's also the first girl born to the Weasley family in several generations.
* Mark in Creator/EdwardEager's ''Half-Magic'' and ''Magic by the Lake''. He is the only boy in a family of four children and his frustration with this is occasionally a plot point.
* In the Literature/VorkosiganSaga, Ekaterin has several older brothers and no sisters, and this is mentioned as being common among Barrayarans of her generation as the result of newly-obtainable sex-selection technology. In contrast to all the tomboyish examples of this trope, she specifically mentions this as being part of the reason why she's a ShrinkingViolet. Ekaterin later deliberately averts this in her own marriage to Miles with two sets of twins followed by one girl to balance her eldest son Nikki Vorsoisson.
** In an earlier example, Drou Koudelka was the only girl in her family with several older brothers and a MissingMom. She's as close to a {{Tomboy}} as Barrayaran society allows. This leads her to become a planetary martial arts champion and eventually the personal bodyguard bodyguard/nanny to the child emperor Gregor.
* Flopsy, Mopsy, Cottontail, and Literature/PeterRabbit.
* In the ''Literature/{{Malloreon}}'', Belgarion and his wife are long-lived, and it has been prophesied that he would only have one son.
* Jenna Heap from ''Literature/SeptimusHeap'' is the only girl in a family with seven boys, and the youngest child as well.
* Posy from ''Literature/TheHungerGames'' has three older brothers.
* Jesse in ''Literature/BridgeToTerabithia'' feels alienated due to having four sisters, no brothers, and a disapproving father.
* Suze Simon from ''Literature/TheMediator'' goes from an only child to having three step-brothers when her mother remarries.
* ''Literature/ASongOfIceAndFire'':
** Margaery Tyrell is the youngest child and the only girl, having three older brothers. Despite that, she plays the part of a PrincessClassic perfectly.
** Asha Greyjoy is the sole female Greyjoy sibling. She had two older brothers who died in the Greyjoy Rebellion, and one younger brother (Theon) who is still alive. Her status as the only girl is further emphasized by the misogynistic, paternalistic culture of the Iron Islands.
** Cersei Lannister is the only girl among two brothers. However, Tyrion's status as TheUnfavorite ascertains that she never felt "outnumbered".
*** In another House Lannister example, Genna Lannister (Tywin's sister) was the only girl among four brothers.
** The Martells have Elia and Arianne, both the only girl with two brothers in their respective generations.
** Lyanna Stark grew up with two older brothers and one younger one, and was a HotBlooded PassionateSportsGirl to match.
** Sansa Stark has two older brothers, two younger brothers, and a younger sister, but feels alienated all the same because Arya is extremely tomboyish. Emphasized when her narration mentions she'd always wanted a sister like Margaery.
* Isabelle Lightwood from ''Literature/TheMortalInstruments'' grew up with two brothers and Jace.
* ''Literature/MaloryTowers'' has Bill, who grew up with seven brothers and turns out to be ''very'' boyish. Alicia also has three brothers, and is quite an unladylike prankster, but this fact is not highlighted as much as Bill's circumstances is.

[[folder:Live-Action TV]]
* Tends to be mentioned as the background of tough female cops, such as Jane Penhaligan from ''{{Series/Cracker}}'' and Kate Todd from ''Series/{{NCIS}}''. The idea being that their reason for seeking to compete in an all-male world is from attitudes gained in their childhood.
* Another "tough female cop" example is Jo Lupo from ''{{Series/Eureka}}''.
* Yet another is Teresa Lisbon from ''Series/TheMentalist'', although she mentions a few times that she practically raised them after their mother died, so the existence of traditional sibling rivalry is questionable.
* In the ''{{Series/Dollhouse}}'' episode "The Target", Echo's persona is implied to have this in her fake backstory; when Boyd asks her if she knows how to use a gun, she replies with, "Four brothers, none of them Democrats."
* Joey from ''Series/{{Friends}}'' has seven sisters and he's the only male.
* Theo from ''Series/TheCosbyShow'' was the only boy in a family of five kids. Despite dealing with usual sibling stuff like a shortage of bathroom time, he seemed relatively okay with it.
* This is the basic premise behind the shortlived sitcom ''Odd Man Out'': a teenage boy has three older sisters and no brothers.
* Daphne from ''{{Series/Frasier}}'' has... what is it? Six brothers? She talks about them a lot.
* The family in ''JustTheTenOfUs'' consists of six daughters and only two sons. And one of the boys is a toddler.
* ''Series/LandOfTheLost1991'': The Sorceress had several brothers. When Annie asked her how she survived, she said she turned them into toads. Annie entertained the thought of doing it to Kevin.
* Wyatt from ''Series/CrashAndBernstein'' was this to his 3 sisters, until he created Crash, and Crash came to life.
* Lindsay Bluth from ''Series/ArrestedDevelopment'' is the only daughter out of 4 siblings. [[spoiler: She's adopted, though.]]
* Luke from ''Series/ModernFamily'' has two older sisters and no brothers. Therefore, he's often left out entirely from episodes that revolve around the SiblingYinYang between Haley and Alex. He seems to find surrogate brothers in his [[ManChild dad]] and Manny (his step-uncle, who's also a kid in his class at school). Later, and to a lesser degree, he finds another surrogate brother in his uncle Mitchell, who wants to adopt a second child but is unsure if he'd be a good parent to a boy, and decides to try out with Luke, but ends up doing all the rebellious "boy" stuff he missed out on in his own childhood instead.
* Karen from ''{{Outnumbered}}'' is the youngest of three and the only girl. Comes up once or twice, though ironically it's usually her mother Sue who gets a sudden urge to have a "girly day" away from the boys; Karen is quite capable of holding her own against her brothers, Jake and Ben.

* Bill from ''TheWho'' song "I'm a Boy" is saddled with three sisters and a mother who acts as if he was a girl as well.

[[folder:Religion and Mythology]]
* In TheBible, Jacob has twelve sons and one daughter, Dinah. Though in some Jewish sources each of the sons, and Dinah, came with a twin sister.
** When Jacob's family migrates to Egypt, the Bible takes the time to mention all of his descendants. Apparently, ''all'' of his fifty-plus grandchildren were boys except one: Serach, who is called "the sister of Asher's sons" (which some interpret to mean a half-sibling who wasn't Asher's birth daughter anyway). We later hear about another granddaughter, Jochebed the daughter of Levi, who may not have been born until they were in Egypt.
** It's worth noting that, since the Bible was concerned with tracing ancestries and LineageComesFromTheFather, daughters aren't always mentioned even when they exist. (For example, we're told David had more than one daughter, but only Tamar is listed with his sons.)

* ''TitusAndronicus'' had 25 sons and one daughter. 'Had' is an important word here: as the play starts he has only five children left, and the number is falling fast.

[[folder:Video Games]]
* Wendy O. Koopa is the only girl of the [[QuirkyMinibossSquad Koopalings]] in the ''SuperMarioBros'' games.
* In the ''VideoGame/{{Warcraft}}'' universe, the three Windrunner sisters have a brother named Lirath who died in the Second War.
* On a slightly lesser scale, a female Dwarf Noble in ''VideoGame/DragonAgeOrigins'' has an older brother and a younger brother.

[[folder:Web Comics]]
* Jyrras from ''Webcomic/DanAndMabsFurryAdventures'' has six older (and much larger) sisters who tend to treat him as a living doll. In his words, "Hell is full of estrogen."
* Summer Winters from ''Moon Over June'' traces her [[DoesNotLikeMen misandry]] to growing up with three older brothers and three younger brothers.
* Surama from ''WebComic/{{Wurr}}'' has four brothers and no sisters, and three of them are older than her.
* Jinx from ''Webcomic/TheWhiteboard'' has eight sisters.

[[folder:Western Animation]]
* ''WesternAnimation/TheSimpsons'' -- While their family isn't "massive," Bart occasionally has pangs of this, with being the only son out of three kids. In one episode, where he becomes jealous of the bond that his sisters, Lisa and Maggie, have, he sets out to try and find a little brother. At one point in the episode, he goes to a local orphanage and gets a boy from there to be his temporary "brother." At first, Bart tried tricking his parents into making a fourth child, but gave up on this when Marge pointed out that even if she and Homer did end up having another baby (which they don't want to happen), the baby may end up being another girl instead of a boy--the idea of having three sisters scared Bart. In the end, the orphan boy Bart befriended ends up being adopted by a family with six daughters, who're likely to make him understand what [[Manga/CardcaptorSakura Syaoran feels]].
* Lor from ''WesternAnimation/TheWeekenders'' is her parent's only daughter and has so many brothers that she loses count of how many there actually are.
* Wendy from ''WesternAnimation/GravityFalls'' is the oldest and only daughter of four children.
* Odd Della Robbia from ''WesternAnimation/CodeLyoko'' has five older sisters [[BigBrotherBully who like to pick on him]].
* Shego from ''WesternAnimation/KimPossible'' has four brothers, who all have super powers as well. The five of them form Team Go, but Shego eventually quit, partly due to finding the dark side more enticing but mostly due to getting fed up with her brothers, or at least her brothers, Hego and Mego--she may get along better with the Wego twins.
* In ''WesternAnimation/DrawnTogether'', one Asian child laborer complains that Spanky's use of Ling-Ling in making shoes is making it hard for him to feed his 48 brothers and one sister.
* The Sumowski clan from ''WesternAnimation/{{Clarence}}''. Sumo's got ten brothers and one sister.
* ''WesternAnimation/{{Braceface}}'' -- Sharon Spitz and Alden Jones are both this: Sharon's the {{middle child|Syndrome}} and only daughter of three kids while Alden's the youngest and only son of four kids.
* The main theme of ''WesternAnimation/TheLoudHouse''; protagonist Lincoln Loud is the middle child and only son in a family of 11 and most plots are set to focus on dealing with his ten sisters.
