Yet, in fiction, people only procreate [[LawOfConservationOfDetail if it's relevant to the plot]], and that includes {{Backstory}}. Some characters do not have canonical relatives at all, and far fewer have siblings unless they are required by the plot. Authors employ this trope for every reason between heightening the angst of ParentalAbandonment and excusing romance {{Genre Blind}}ness.

This is even more true in adoptive families. Whether the protagonist is HappilyAdopted or [[OrphansOrdeal not]], fictional characters rarely adopt more than one child -- again, unless the plot calls for it. Families with both adopted and biological children are even rarer.

In a WorldOfNoGrandparents, all parents are also only children, which means no one can raise orphans except butlers, strangers, or [[OrphanageOfFear the school of hard knocks]]. Usually, the orphan in question is also an only child.

In shojo romances, the PluckyGirl heroine has seemingly avoided all interaction with the opposite sex until meeting the TroubledButCute school bully. In most cases, PluckyGirl doesn't have any brothers. If she does, they are either too young to provide any model of what she is dealing with, or old enough to be in the parenting role.

* Franchise/{{Superman}} is doubly so - he was the only child of the Jor-Els (though granted, they might have had more if it weren't for the [[EarthShatteringKaboom slight impediment of being dead]]), and he's the only child of his adopted parents. Understandably justified as his birth parents died, along with his entire planet when he was a baby and the Kents couldn't have kids of their own.

* From book to the first movie of ''Film/TheSisterhoodOfTheTravelingPants'' they removed one of Tibby's younger sibling so that she only has one, Bridget's brother so that she's an only child and Lena's sister so that she can go to Greece by herself. Lena's sister who we see in the second movie must have been jealous.
* ''Film/CatchMeIfYouCan'' portrays Frank Abagnale, Jr. as an only child. In RealLife, he had three siblings.

* Noah and Allie from ''Film/TheNotebook'' are both only children.
* Almost all of the major characters in ''Film/HarryPotter'', including the title character and protagonist himself, are only children.
* Bella Swan, the protagonist from ''Film/{{Twilight}}'', is an only child. Although Edward Cullen has adoptive siblings, Edward is biologically an only child as well.

* ''Series/OurMissBrooks'': Teenagers Walter Denton and Harriet Conklin are Justified in ''Series/The100''. Most of the characters were born on The Ark, a space station constructed from 12 original stations to shelter the remnants of the human race after a nuclear war. To conserve resources, the Ark has a [[PopulationControl strict one child policy]], so everyone in the main cast is an only children.
* ''Series/TheMunsters'': Eddie Munster
child with the exceptions of Bellamy and Octavia Blake, the latter of whom is an illegal second child who was kept hidden for most of her life.
* ''Series/AgentsOfSHIELD'':
** Most of the titular agents seem to be only children: Fitz explicitly states that his only relative is his mother, and Skye was raised in an orphanage and never kept a foster family long enough to gain siblings that way. Simmons mentions her parents often enough to make it seem like that's the extent of her family unit, particularly since when she thinks she's about to die her wish is to pass messages on to her parents and Fitz, but no-one else. Coulson and May's parents are, respectively, frequently mentioned and featured in cameos, without any siblings in the picture, and Coulson later described as a classic only child. Meanwhile, Triplett appears to be the sole heir to his legendary grandfather's stash of cool vintage S.H.I.E.L.D. tech.
** The only aversions are Ward and Koenig: Ward mentions two brothers and a sister (the two brothers have played important roles in his back-story and his older brother becomes a major player in Season 2, though the sister has yet to figure), while Koenig appears to have a suspiciously well-stocked army of [[BackupTwin Back-Up Twins]].
** Also {{Averted}} for Simmons in the comics, where it's mentioned that she has a brother and a sister (and is TheUnfavorite to her dad). It's unclear whether this is true for her in the show or not.
** This is all possibly {{Justified}} in that S.H.I.E.L.D. has a reputation for hiring loners, and lacking an extended family network surely helps in this regard. Note that Ward, the only main character to mention having siblings, makes it explicit that they no longer have anything to do with one another.
* Very much averted in ''Series/TheBigBangTheory''. Howard grew up
an only child, in spite but discovered a half-brother. Sheldon has an older brother, George, and a twin sister, Missy; Leonard has an unnamed older sister and a younger brother, Michael; Penny has an unnamed brother and sister; and Raj has a younger sister, Priya, three unnamed brothers, and another unnamed sister. Bernadette, Amy, and Stuart have an unspecified number of his parents having been married over one hundred years.siblings as well. Numerous aunts, uncles, cousins, nieces, nephews, and grandparents are also mentioned throughout the series.



** Andrew, interestingly, originally had to keep being introduced as "Tucker's brother," even though Tucker was a [[MonsterOfTheWeek villain of the week]] who wound up being much less important to the series and only appeared in one episode.
* In ''Series/TheSarahJaneAdventures'' every protagonist is an only child including Sarah Jane herself. Her son is a special case, as he was grown in a lab by aliens.
** Sky - Luke's new adopted sister in Series 5 - has similar-though-not-matching reasoning for being an only child (biologically, anyway). On top of that, Sarah Jane's parents died when she was a baby, which justifies her lack of siblings. Meanwhile Maria's dad and Clyde's mum are divorced from partners with whom they didn't work out [[spoiler:and Clyde's dad ran off with his wife's sister, whom it's revealed he impregnated, giving Clyde an unseen half-sibling/cousin]]. The only one with no excuse whatsoever is Rani, and to be fair not all parents in the present-day want more than one child anyway.

* In ''Series/TheSarahJaneAdventures'' every protagonist ''Series/{{Carnivale}}'' provides a [[JustifiedTrope justified]] case of this, at least according to [[AllThereInTheManual the "Gospel of Knauf"]] that outlines the series' mythology. One of the pitfalls of coming from a line of historic [[TheChosenOne Avatars]] (one of the super-powered humans at the heart of the series' mythology) is that a woman is rendered infertile after giving birth to an Avatar--who, as per the rules of the universe, can only be the firstborn male child of his family. Hence, Avatars can only have older female siblings, and are very often only children.
* Paige Matthews of ''Series/{{Charmed}}'' grew up as
an only child including Sarah Jane herself. Her son is a special case, as he was grown in a lab by aliens.
** Sky - Luke's new adopted sister in Series 5 - has similar-though-not-matching reasoning for being an only child (biologically, anyway). On top of that, Sarah Jane's parents died

** Abed mentioned that Britta having a brother who works
with his wife's disabled kids in the pilot, and I'm almost certain Troy mentioned having siblings.
* In ''Series/{{Degrassi}}'', the vast majority of the LoadsAndLoadsOfCharacters that have appeared over the years are only children: Snake (older brother), Liberty (younger brother), Craig (half-sister), and Holly J (older sister) are some of the few exceptions.
** They seem to be averting this in the post Season 10 episodes. Out of the characters still on after season 13, Drew had a stepbrother, Alli has an older brother, Miles has a brother and
sister, whom it's revealed he impregnated, giving Clyde Tristan has a stepbrother, Maya has an unseen half-sibling/cousin]]. The only one with no excuse whatsoever is Rani, and to be fair not all parents in the present-day want more than one child anyway.older sister, etc.



** Rose was an only child for her tenure as a full companion, but had a baby brother by the time of the series four finale due to [[spoiler: Jackie and alt-Pete getting together.]]



** River has a younger brother, although, like in Rose's case, we only hear about him in what is the epilogue for her parents' story arc and it's unclear if they ever met. Then again, given her parent's dangerous, unsteady lifestyle and how it got, you can understand why her parents might have refrained from having another kid untill their space travel days had come to an end.
** Sort of justified, however, in that someone with little ties to their place of origin to begin with would simply be more likely to follow an extraterestial oddball on a joyride through time and space than someone whose siblings or parents would get worried.
* In ''Series/SavedByTheBell'', Kelly and Slater are the only children to have siblings. Jessie does end up gaining a stepbrother. Zack, Screech, and Lisa are all only children.

* Almost all of the core characters on ''Series/TeenWolf'' are only children. Scott, Stiles, Allison, Lydia, Kira, Jackson, Malia and Liam are all only children. Derek and Isaac have siblings, but Isaac's brother is dead, and Derek's two sisters were either murdered or PutOnABus to South America. If Derek had any other siblings, they likely died in the fire along with the rest of his family before the series began.
** Technically, Malia had a younger sister when she was a child, but she died in a car accident. And since Malia turned out to have been adopted, she wasn't biologically related to the girl anyway.
* Averted in ''Series/{{Friends}}'': Joey has seven sisters, Rachel has two sisters, Phoebe has a twin sister and a half-brother, Monica and Ross are brother and sister, leaving Chandler as the only only-child. And that's justified seeing as parents hated each other, his Dad was gay and they [[{{ParentalNeglect}} barely noticed the son they did have.]]
* On ''Series/{{Zoey 101}}'', Zoey is the only one of the main characters to have a sibling, her brother Dustin. Lola mentions a younger sister in passing (season three's "Surprise") who is never mentioned again and never seen, and none of the other characters seem to have siblings at all.

** Also {{Averted}} for Simmons in the comics, where it's mentioned that she has a brother and a sister (and is TheUnfavorite to her dad). It's unclear whether this is true for her in the show or not.

* Franchise/WonderWoman's [[strike: birth]] creation into a league of immortals doesn't raise as many eyebrows as to why few children are born. Since they don't die, if they had new children showing up as often as humans do, their home island would be standing room only after a few centuries.
** Granted, Pre-Crisis Diana had a Black twin Sister. [[http://en.wikipedia.org/wiki/Nubia_(comics) No, really]].
* [[ComicBook/GreenArrow Oliver Queen]] and his proteges.

* Almost all the main characters in both ''Series/BuffyTheVampireSlayer'' and ''Series/{{Angel}}'' seem to be only children: Buffy ([[CosmicRetcon pre-Dawn]]), Xander, Willow, Cordelia, Fred, Faith, Spike and Wesley all seem to have no siblings. Only Angel (sister), Gunn (sister), Tara (brother), and Andrew (brother) are known to have had siblings - and two of those four were either already dead or were killed off straight away!

* Nearly all companions in ''Series/DoctorWho'' are only children: Rose ([[spoiler: until Jackie and alt!Pete get together, but her baby brother is mentioned only once, and she's an only child for the majority of her tenure]]), Mickey, Donna, Amy, Rory, and Clara are all only children. The exceptions are Martha (a brother and a sister) and technically Captain Jack (who, as it turns out, had a brother, but this fact is only revealed in his spin-off ''Series/{{Torchwood}}'').
** Adric had a brother. [[spoiler:Emphasis on had]].
** River has a younger brother, although, like in Rose's case, we only hear about him in what is the epilogue for her parents' storyarc and it's unclear if they ever met. Then again, given her parent's dangerous, unsteady lifestyle, and how it got you can understand why her parents might have refrained from having another kid untill their space travel days had come to an end.

Added DiffLines:

* ''WesternAnimation/MeetTheRobinsons'' has Wilbur living in a [[TheClan large, extended family]] that includes aunts and uncles, great-aunts and great-uncles, cousins once removed and two people whose relationship nobody's even sure of...but no other children. (Though, for that matter, no one else in his parents' generation seems to be married.) His parents almost adopt Lewis as a second child, before realizing [[spoiler:he's actually Wilbur's own father from the past]].
