History Main / EveryonesBabySister

* [[MeaningfulName Cheedo the Fragile]] in ''Film/MadMaxFuryRoad'' is the youngest of Immortan Joe's [[SexSlave unwilling Wives]] and, as of the time of the film, the only one who hasn't already been raped by him due to being [[BreedingSlave too young to breed]], so the other Wives are extremely protective of her and try to shelter her from Joe's true monstrosity, which results in StockholmSyndrome where Cheedo at one point attempts to turn herself into Joe while on the run. The prequel comic also shows that The Dag went so far as to directly interfere when Joe tried to rape Cheedo, and was savagely beaten for it, causing Cheedo to blame herself.

* ''[[Webcomic/{{Nijiyon}} Nijyon Animation]]'': Episode 9 has Kasumi hosting a competition for the school idol club to {{Invoked|Trope}} this, particularly to make ''herself'' this since little sisters relate to cuteness, it means being the club's little sister means being the cutest idol. Shizuka (a first year and one of the youngest students)), Shioriko and Mia (the latter two already little sisters), and Ai (who has a little sister dynamic with her CoolBigSis Misato) are also consider candidates. It's ultimate Rina that's picked as the club's sister when she wins them over (including Kasumi) with a pair of PuppyDogEyes.
** For the [=R3BIRTH=] trio, Lanzhu considers Shioriko and Mia her little sisters, but the younger girls see ''here's as the little sister that's a handful.

* [[HalfHumanHybrid Steven]] from ''WesternAnimation/StevenUniverse''. The Crystal Gems are his {{Parental Substitute}}s since his mom, their former leader, suffered the supernatural equivalent of DeathByChildbirth. His [[AllLovingHero personality]] also gets him "little brother" status with every teenager in Beach City, [[MyFriendsAndZoidberg except]] [[JerkWithAHeartOfGold Lars]] (not that this dissuades Steven from trying). As of Season 5, even Lars has warmed up to Steven.

* On a meta level, Willow from ''Series/BuffyTheVampireSlayer'' - the writers quickly discovered that threatening her was one of the best ways to get the audience to react. An aphorism among the writing staff was "When in doubt, put Willow in danger". As Willow grows more worldly in later seasons this role was taken over by Dawn, the Scoobies falling over one another to give their lives to protect her from Glory and other threats.

* Similar to the X-Men, the ''ComicBook/JusticeSocietyOfAmerica'' have done this since being revived in TheNineties, and retooled so that, rather than simply be [[UsefulNotes/TheGoldenAgeOfComicBooks the Golden Age]]'s primary team of heroes, the remaining members act as mentors and teachers to the [[LegacyCharacter legacies, proteges, and descendants]] of the original team and/or heroes they were friends with. Though they've had a few characters who fulfil the role, the original was [[Franchise/TheFlash Jesse Quick]], while the most prominent and popular was [[ComicBook/StarsAndSTRIPE Stargirl]], whom pretty much everyone sees as either a surrogate daughter or a kid sister. She seems aware of this and is often ''annoyed'' by it.
* ''ComicBook/BlackCanary'': Among the Justice Society of America, she had something similar to the above prior to their reformation, as most of them have known her since she was born, so they see her as their niece. In ''JLA: Year One'', her status as the only girl on the team and her youth (she was 19 at the time, while the others appeared to be in their 30s by comparison) lead to this, something she was ''vocally'' annoyed with as she frequently told them off for treating her like a damsel they had to protect. In ''ComicBook/BirdsOfPrey'', though the UndyingLoyalty goes both ways, Dinah being in danger seems to strike the biggest reaction from the others.
* Aviva Weinberg of ''ComicBook/RelativeHeroes'' is literally the baby sister of her team as it's made up of her siblings. When the Weinbergs help with the invasion of Zandia several members of ComicBook/YoungJustice and their allies make sure to keep her out of the line of fire or at least behind forcefields and bulletproof individuals since she is incredibly young for a superhero, even when compared to the rest of the group which is almost entirely made up of teenagers.
* In ''ComicBook/{{Runaways}}'', Molly and Klara fill this role, to varying degrees -- Molly is ''everyone's'' baby sister, but Klara is more of a little sister to Nico and Karolina, while Chase and Victor treat her more like TheLadette. Oddly enough, the "baby sister" aura even seems to affect other people in the Marvel universe -- for instance, during ''ComicBook/SecretInvasion'', Speed of the ComicBook/YoungAvengers literally went out of his way to keep Molly and Klara safe during a battle with the Skrulls.
* ''ComicBook/SecretAvengers'' Volume 2 seems to play [[Characters/MockingbirdMarvelComics Mockingbird]] like this during the "[[BreakTheHaughty How to Maim a Mockingbird]]" arc. ComicBook/{{Hawkeye}}, her ex-husband, is visibly torn up from seeing what happened to her during the arc, ComicBook/BlackWidow stops joking and talks to her the way that a worried sister would when she realizes the seriousness of the situation, and [[Characters/IronManHeroes War Machine]] actually ''quits the team'' in protest and disgust at the fact that [[Characters/SHIELDDirectors Maria Hill]] allowed Mockingbird to get into such a situation (and is joined with Hawkeye in this), while Maria Hill herself is clearly not happy with herself for allowing this to happen and makes a promise to find her. Even ''[[Characters/MarvelComicsTaskmaster Taskmaster]]'', the TokenEvilTeammate, is pretty shocked to see how broken she is and is clearly concerned for her welfare.

* On ''Series/{{NCIS}}'', the best way to make something personal for the entire team is to threaten Abby Sciuto. This can be seen when you compare an episode like "Bloodbath", where someone is after Abby, to episodes like "Frame Up", "Reveille", "Probie", and "Recoil", where the threats against Tony, Kate, [=McGee=], and Ziva are taken seriously, but not as personally.
** Newcomer Ellie Bishop appears to be falling into this role too; everyone has taken her under their wing to some extent, and they've all expressed a desire to beat the tar out of her adulterous husband. When her three ''actual'' older brothers show up, they take the trope to its logical extreme.
* ''Series/{{Firefly}}'': Most of the time, when a crew member gets injured, it gets more or less shrugged off. When Kaylee gets shot in the pilot, it's a different story. Mal threatens to [[ThrownOutTheAirlock toss Simon into space if he fails to save her.]] Jayne, who rarely shows concern for anyone, immediately goes after the man who pulled the trigger.
-->'''Book:''' You're not going to kill this man.
-->'''Jayne:''' Well, [[ColdBloodedTorture not right away]].

--> '''May (of Simmons):''' She's only a kid.
* On ''Series/OnceUponATime'', Henry is the only character who could have gotten Emma, Snow, Charming, Regina, Rumplestiltskin, and Hook [[spoiler:on a ship to Neverland together.]] This may be a factor of [[TagalongKid his age]] and the fact that he's [[TangledFamilyTree related to almost the entire main cast]].
* ''Series/SamuraiSentaiShinkenger'': Kotoha Hanaori might perceive herself as TheLoad despite her best efforts to improve but the rest of the team digress. She simply doesn't have as much trainning as the rest of them (minus [[ClassClown Chiaki]]). If she is in a serious danger, they will drop everything to save her.
** Mostly averted with Chiaki Tani, who ties with Kotoha as the least experienced team member, but unlike her is an annoying goof with an attitude problem, so he naturally invokes somewhat less protective feelings from the rest of the team.
* ''Series/KamenRiderExAid'': Emu Hojo's [[AllLovingHero kind]], [[IncorruptiblePurePureness optimistic]] nature tends to incite BigBrotherInstinct in people around him. [[GoodIsNotSoft He]] is a capable [[TheChessmaster strategist]] and [[BatmanGambit manipulator]], but most of all, he wears his ideals and heart in the open, which makes him an easy [[BreakTheCutie target]]. The [[DysfunctionJunction CR Crew]] will readily drop fighting with each other to help him.
** Nico is the youngest member of the crew and also keeps on inserting herself into dangerous situation despite being the only civilian on a team of Kamen Riders. Also, she hates to be babied, but does not help matters by being a [[BrattyHalfPint Bratty Half Pint]] [[PintSizedPowerhouse Powerhouse]].
* ''Series/KamenRiderBuild'': Everyone in Nascita family dotes over Misora, the band's young NightmareFuelStationAttendant, in some way. Granted, [[AbhorrentAdmirer Kazumi]] is inevitably a creep about it, but he cares too. They try their best to shield her from both the [[CosmicHorrorStory supernatural]] and [[WarIsHell mundane]] horrors going on outside, but it's mostly pointless. She knows and is most hurt by them trying to keep secrets from her. Nothing can stop her from trying to help them, but nothing will stop them from trying to keep her away from battle either.
* ''Franchise/LawAndOrder'':
** This tends to happen with the Assistant District Attorneys. We've only really seen it played out with Claire Kincaid and Alexandra Borgia on the original ''Series/LawAndOrder'' and Alex Cabot on ''Series/LawAndOrderSVU'', but it did play out with all three of them.
** On ''Series/LawAndOrderUK'' with junior CP Alesha Phillips. The reactions from the rest of the team when she's raped make it obvious that harming her is a bad idea.

* On ''Series/GuidingLight'', Abby (who was already this to the townspeople) was attacked and nearly raped by a gang member. When the rest of the gang began making threats to her in the hopes of preventing her from testifying, the TokenGoodTeammate (a) reminded them of what he'd done, clearly trying to invoke EvenEvilHasStandards, and (b) informed them that, "You know who she looks like? Tony's (gang member's) sister. Might as well have been ''her'' he tried to mess with."
** Lucy Cooper falls into this role also, literally being this in the Cooper family.

* ''Series/{{Community}}'': As the youngest member of the study group, Annie Edison gets treated this way a lot, especially in early seasons (in later seasons she mostly proves that [[WiseBeyondTheirYears she's more mature than the rest of them]]). This causes friction with her primary love interest, Jeff, who is sixteen years older than her. Early on, he repeatedly uses her age as an excuse not to date her. In later seasons that excuse mostly disappears, and Jeff's self-loathing is the main thing that keeps them apart.

* Merrill from ''VideoGame/DragonAgeII'' is this to most of the party. Only Fenris and Anders dislike her due to her use of BloodMagic.
** In a non-mage-Hawke playthrough, Bethany - who is Hawke's actual little sister - also qualifies whenever she's present. ''Everyone'' in the party likes her, including the staunchly anti-mage Fenris; Anders is lukewarm at worst. [[spoiler:If she goes to the Circle instead of dying or joining the Grey Wardens, this trope remains in effect even after Act 1.]]
* Sheva Alomar of ''VideoGame/ResidentEvil5'' is described as the "little sister" of her BSAA squad by her C.O. and mentor, being the youngest and greenest member. Of course, Chris Redfield is told of this long after she's ably demonstrated her own competence and badassery, and his survival depends on her throughout the mission as much as hers depends on him.

* Phym in ''VideoGame/GodEater3'' immediately becomes the darling of everyone in Chrysanthemum after she is rescued by the Protagonist from an attacking Anubis, and she is especially held dear by the Protagonist (who is her ParentalSubstitute) and Claire (who the narrative treats as her CoolBigSis most of the time). [[spoiler:When she is forcibly taken away by Dr. Inukai midway through the game, the Hounds immediately devise a plan to rescue her even if it means going against Gleipnir, and in the final part of the main story they even go against an Ash Tempest-corrupted Odin unit she is trapped in after she turned herself in to Gleipnir's command to prevent other [=AGEs=] from being used to power the Odin units.]]

* ''VideoGame/StellaGlow'': Marie, an amnesiac little girl [[TheHero Alto]] found and took under the 9th Regiment's care, quickly becomes the emotional support to everyone in the Regiment, helping to lift everyone's spirits when they're down. Everybody on the team likes her and become extremely protective of her. Even Queen Anastasia likes her, comparing her to the little sister she never had and was considering adopting her as one. [[spoiler:When [[TheHeavy Xeno]] takes her away in the endgame, the heroes are devastated, but quickly become determined to save once they're motivated.]]
* In ''VideoGame/{{Omori}}'', Sunny is considered the baby of the group due to him being the youngest.
* ''VideoGame/GuardianTales'': The Little Princess, the [[TheHero Knight's]] adventure companion. All of the heroes of Heavenhold treat her like she was their youngest sister rather than a [[AuthorityInNameOnly royal princess]], and [[ModestRoyalty she prefers to be treated as such]]. That doesn't mean she hasn't seen her fair share of [[PintSizedPowerhouse shining]] [[RoyalsWhoActuallyDoSomething moments]] though, examples being her fighting Invaders with just a baseball bat, [[spoiler:sneak attacking an evil version of her Knight, although [[KickTheDog she gets thrown off their back towards a wall afterwards]], rendering her unconscious for a while]], and [[spoiler:reversing the effects of a bio-weapon that had just detonated and killed everyone in the area, albeit unconsciously]]. In addition, [[spoiler:in an alternate timeline where the Knight suddenly disappears, as rumors of [[WhatTheHellHero the Knight abandoning their duty]] begin to circulate, she becomes [[DespairEventHorizon overcome with despair due to all the deaths happening around her that could've been prevented]], and she begins taking combat and leadership lessons in hopes of becoming the world's new hope, becoming the [[FutureBadass Future]] [[TookALevelInCynic Princess]] over the course of ten years.]]
* In ''VideoGame/{{Rosenkreuzstilette}}'', it is revealed in the final confrontation with BigBad Count Michael Zeppelin that the action which triggered the RKS rebellion against the Holy Empire was [[spoiler:Kahl Palesch]] attempting to assassinate the count's young and innocent daughter Iris. This energized him and the members of RKS, who treat Iris like a little sister, to fight back and stop the resurface of Magi persecution. [[spoiler:And then it turns out that Iris ''invoked'' the trope so as to spark a war [[ItAmusedMe for her amusement]] and as part of a plan to [[GodhoodSeeker ascend to godhood]].]]

* This is not an uncommon trope in otome games (dating games aimed at mainly heterosexual women.) Since the protagonist in these games is typically female and the player determines who she gets together with, all the dateable men (and even some dateable/friendship route women)like the main character and become fairly protective of her. This, in turn, means that any time a bad guy [[TooDumbToLive messes with the protagonist]] you can be sure one of, if not all of, the dateable characters will come after them, invoking this trope. This is particularly true in games like VisualNovel/CodeRealize and London Detective Mysteria.

* Invoked by Hun in the 2003 ''WesternAnimation/{{Teenage Mutant Ninja Turtles|2003}}'' cartoon, in which April is a mix of little sister and [[CoolBigSis big sister]] to the turtles (she even acts as [[TeamMom a motherly figure]] sometimes):
-->'''Hun''': ''Those green freaks feel great affection for you. Losing you should take the fight out of them.''

* [[HalfHumanHybrid Steven]] from ''WesternAnimation/StevenUniverse.'' The Crystal Gems are his {{Parental Substitute}}s since his mom, their former leader, suffered the supernatural equivalent of DeathByChildbirth. His [[AllLovingHero personality]] also gets him "little brother" status with every teenager in Beach City, [[MyFriendsAndZoidberg except]] [[JerkWithAHeartOfGold Lars]] (not that this dissuades Steven from trying). As of Season 5, even Lars has warmed up to Steven.

* Bonnie from the XY saga of ''Anime/{{Pokemon}}'' is Clemont's little sister, and his BigBrotherInstinct is combined with similar protective feeling from Ash, Serena, and their Pokémon.

* ''Series/{{Arrow}}'': Despite Oliver Queen having a genuine little sister (Thea, whom he'll go to [[KnightTemplarBigBrother extreme lengths to protect]]) this role goes to Felicity Smoak instead. She's the only non-combatant on TheTeam, and Ollie and Diggle go to great lengths to ensure her safety and keep her hands clean.

** Padparadscha seems to be this for the Off-Colors. Lars, a self-admitted DirtyCoward even takes on the robloids to protect her and Rhodonite is quick to guard Padparadscha as well. A good part of this, beyond her size, is that Padparadscha is a "flawed" Sapphire. In Gem society, Sapphies serve as advisers because of their ability to see into the future. However, Padparadscha's visions are retroactive, meaning she is usually not aware of the danger until after it's been resolved.

* Comicbook/{{Nightwing}}: Dick Grayson began as Franchise/{{Batman}}'s KidSidekick, which in contemporary continuity was between 10-15 years ago. This makes him one of the most known superheroes in the world despite his relatively young age, and one that [[SoProudOfYou all of his older colleagues]] are ''very'' proud of to see grown into a [[NiceGuy fine young hero]]. Thus, if Dick calls on any other superhero for help, they will usually come running. These same older heroes (and some {{antivillain}}s, like ComicBook/{{Catwoman}}) will ''rain down the hurt'' on anyone who dares to harm Nightwing. ''[[PapaWolf Especially Batman]]''. In his solo series, this has saved his life more than once, as small-time villains who had defeated Nightwing in combat deliberately let him live because they knew that wasn't the kind of heat that they wanted to bring upon themselves.

* ''Series/DarkMatter'': Five, as a sixteen-year-old and the only non-criminal member of the crew, tends to be kept on the ship for her own safety most of the time, despite the fact that her [[TeenGenius technical expertise]] is extremely useful on the rare occasion she ends up on a mission. This creates the odd dichotomy that the crew both know how competent Five is but still treat her as younger than she really is. In "Wish I'd Spaced You When I Had the Chance," when Five gets kidnapped, Three asks around for the [[TagalongKid "kid"]] he was with. A local who saw her get taken is bewildered, because while she's young, she's also clearly not a child. Also, threatening or hurting Five is a good way to make the entire crew [[BigBrotherInstinct want to kill you]].

* ''Fanfic/ThisIsAWildGameOfSurvivor'': Mostly to Ha-ri, his actual older sibling, but Woo-jin qualifies as this. Ha-ri has been overprotective of him since the moment their parents brought him home from the hospital as babies. Joon-yeong falls in love with him immediately after meeting him and can be protective of him, particularly when comforting him after Ha-ri finds out about their relationship and in feeling responsible for Woo-jin breaking his wrist and nearly getting killed. Dae-su also promises to kick the ass of anyone who hurts him, be it homophobia or Joon-yeong breaking his heart. Tellingly, every one of the classmates present to hear the bastard soldier insult Woo-jin for grieving is pissed off enough to throw peaches at the soldier.

* In ''VisualNovel/Nightshade'', out of the group of friends, Kasumi is the most innocent and child-like, even though she is only a year younger than the sixteen year old Enju, and all of them act as her older siblings.

Compare and contrast TheChick, TheHeart, TheCutie, the TagalongKid, {{Moe}}, AndYourLittleDogToo.

* ''Webcomic/CursedPrincessClub'': Gwendolyn is this for the Cursed Princess Club, both because they want to make their newest member feel welcome and because her sweet, nonconfrontational personality and intense AppearanceAngst make them eager to help her overcome her insecurities. At certain points, they even express a desire to give Prince Frederick, Gwen's unwilling fiancé who called her ugly and thus gave her those insecurities, a piece of their minds. [[spoiler:That desire becomes inconvenient when Frederick eventually stumbles upon the club (which they actively keep secret from non-members). They initially try to drug him to sleep to make him think his encounter with them was just a dream, and when that fails they come close to giving him a NoHoldsBarredBeatdown while angrily berating him for how he has treated Gwen. But they soon find out that Frederick has come to be genuinely attracted to Gwendolyn by that point, making them realize they were overreacting.]]

* ''Wiki/SCPFoundation'': [[http://www.scp-wiki.net/scp-085 SCP-085]], "Cassie," is a living 2D drawing of a young woman who thought she was living a reasonably productive life in a post-apocalyptic wasteland until she found out the truth behind her situation. The Foundation as a whole feels pretty bad about everything that's happened to her, partly because she only exists because they were playing around with some other [=SCPs=]. A lot of effort is made to make her feel comfortable, from finding things she can use in her 2D state to discussing getting her a psychiatrist.

* In ''Machinima/RedVsBlue'', Michael J. Caboose serves this role over time. Even when the [[FriendlyEnemy "opposing" teams]] are insulting one another, they make time to be nice to him, and actually make an effort to make sure he feels good about himself. The times when he is upset by an outside party are actually treated as deadly serious and horrible things to do, especially by [[BigBrotherInstinct Tucker]].

** On ''Series/LawAndOrderUK'' with junior CP Alesha Phillips. The reactions from the rest of the team when she's raped make it obvious that harming her is a BerserkButton for them.

* ''Series/DarkMatter'': Five, as a sixteen-year-old and the only non-criminal member of the crew, tends to be kept on the ship for her own safety most of the time, despite the fact that her [[TeenGenius technical expertise]] is extremely useful on the rare occasion she ends up on a mission. This creates the odd dichotomy that the crew both know how competent Five is but still treat her as younger than she really is. In "Wish I'd Spaced You When I Had the Chance," when Five gets kidnapped, Three asks around for the [[TagalongKid "kid"]] he was with. A local who saw her get taken is bewildered, because while she's young, she's also clearly not a child. Also, threatening or hurting Five is a [[BerserkButton good way]] to make the entire crew [[BigBrotherInstinct want to kill you]].

*** The new playable character [[TokenMiniMoe Sophia]] in ''VideoGame/Persona5Strikers'' being both the newest Phantom Thief and an [[ArtificialIntelligence AI]] with little knowledge of but an earnest desire to learn about humanity, Sophia becomes this to the rest of the Thieves, who are extremely protective and supportive of her and her endeavors to learn about herself and human hearts. They [[BerserkButton do not take it kindly AT ALL]] (especially Ryuji) when the voice in the Okinawa Jail [[spoiler:and Sophia's own creator Kuon Ichinose]] insult and declare her existence a mistake and meaningless.

[[folder:Film]]

When a BigBad sets this character in their sights, it immediately [[ItsPersonal becomes personal]] for every other character involved. Somehow, it never occurs to the BigBad that this may well make the heroes ''more'' dangerous, not ''less''.

* ''Webcomic/CursedPrincessClub'': Gwendolyn is this for the Cursed Princess Club, both because they want to make their newest member feel welcome and because her sweet, nonconfrontational personality and intense AppearanceAngst make them eager to help her overcome her insecurities. At certain points, they even express a desire to give Prince Frederick, Gwen's unwilling fiancé who called her ugly and thus gave her those insecurities, a piece of their minds.

* [[Characters/XMen80sMembers Kitty Pryde]] of the ''ComicBook/XMen'', who might be the closest to an AlternateCompanyEquivalent to Nightwing in this respect. She joined the X-Men when she was 13 as a rookie, and unlike the ComicBook/NewMutants, whom were her age but joined after, she trained directly with the main team and was close with each one.

* [[ChildProdigy Chiyo-chan]] in ''Manga/AzumangaDaioh'' is a downplayed example; while the series is a SliceOfLife story free from major conflict, if Chiyo is threatened in any way, or if she gets mocked by a bully for [[GradeSkipper her age]], the other girls are very quick to protect her. Sakaki in particular has a BigSisterInstinct toward her, using her innate athletic ability to make up for Chiyo's poor performance in P.E. Even Tomo, who's normally TheGadfly, eases off on Chiyo if she feels like she's gone too far in her teasing.
