Congratulations! You just received a new [[FiveManBand team member]]; and [[SlidingScaleOfGenderInequality against all odds... it's a girl]]! Everyone on the team is happy to finally have a new girl to help balance out the gender ratios... everyone except for the sole girl already on the team! She isn't happy about the equaling of the gender ratio. Turns out, she actually took pride in the fact that she was the only girl on the team. Like the queen bee in a beehive[[hottip:*:as worker bees are female, the queen is actually part of a majority gender-wise. She might be considered a Smurfette fertility-wise, as the worker bees are infertile]], [[TheSmurfettePrinciple The Smurfette]] doesn't take kindly to her male teammates gushing over the new girl, and takes great exception to her presence. As luck will have it, however, the Smurfette will end up being accused of [[CommanderContrarian just being catty because the new friend is a girl]].

In stories where StatusQuoIsGod, you'll see the Smurfette turn out to be right because the new girl was either the BitchInSheepsClothing or a SixthRangerTraitor, typically with only Smurfette [[CassandraTruth to see through the act]]. In stories where there can be legitimate progress, the new girl will just be a target of shallow jealousy because the new girl is [[TomboyAndGirlyGirl markedly more feminine]] or [[OneOfTheBoys able to get along with the men more easily]]. In the end, the two women may end up becoming friends. [[TakeAThirdOption Sometimes these two courses for the story get combined, leading to more interesting results]].

A subtrope of TheSmurfettePrinciple. Compare to the AlphaBitch (who's just a territorial female, [[NoPunIntended period]]). Almost AlwaysFemale, though a gender inversion may occur, especially in series that use TheOneGuy.

[[folder: Anime ]]

* In ''OnePiece'', after [[HighHeelFaceTurn Nico Robin]] joins the crew, Nami is the first of the crew members to voice her objection over Robin forcing herself into the crew. Robin manages to win Nami over quickly by giving her money, and later she refers to Robin as her cool big sis.
** Then it's subverted -- Usopp and Zoro were much more negative about Robin, while less bitchy (in fact, Zoro remained distrustful of her until partway through the next major arc), and Nami's objections are less about Robin's gender, and more because she was TheDragon of the previous arc's BigBad. The fact that Nami had an "older sister" type friendship with Vivi - the princess whose kingdom went through intense turmoil because of Robin's actions - and probably had the most empathy of anyone in the crew for the pain she went through probably had something to do with it as well.
** Speaking of Princess Vivi, it should be pointed out that Nami had no objections to letting her travel with the crew back when she was still the only woman in it. In fact, it was ''her'' idea.
* ''TengenToppaGurrenLagann'': [[ActionGirl Yoko]] has some difficulty dealing with [[MadScientistsBeautifulDaughter Nia]] when she joins Team Dai-Gurren, more because her {{Moe}}-ness wins over the guys than because of her being the {{Big Bad}}'s daughter. They eventually come to terms before the TimeSkip.
** Possibly justified in that, back then, she considered Nia dead weight: they were fighting a rebellion, and Nia had no combat skills. Then Nia won her over via showing her SilkHidingSteel side, specially via not even blinking when Yoko released her from a monster via ''shoting said moinster when it was holding Nia hostage'', and later said she complettely totally trusted Yoko to not fail a shot that could have potentially killed her.
* Played straight and then downplayed with Sanae from CaptainTsubasa:
** Played straight and [[PlayedforLaughs for absolute comedy]]: in Yayoi's first apparition in the elementary school arc, Sanae was ''pissed'' and openly jealous. It's not helped by a totally oblivious Yayoi revealing her past with Tsubasa and, well, by both of the being little girls back then. (They're hinted to have become good friends as teenagers.)
** Downplayed: Sanae showed some jealousy when Kumi arrived, but this was mostly because she openly said she joined due to Tsubasa, and other than that they're best friends. Also, Sanae is the one who brought Yukari to the team and never showed anything similar to jealousy towards her.

[[folder: Comic Books ]]

* ''MarvelStarWars'': Princess Leia shows signs of this when a {{Fiery Redhead}}ed wingmate of Luke's, one Shira Brie, starts flirting with him, although she gets over it. Then Luke discovers that she was an Imperial DeepCoverAgent after unwittingly shooting her down during a mission; she survives, and eventually returns as [[DarkActionGirl "Lumiya"]].
** In the same series, Leia also dislikes Dani, a Zeltron woman who travels with them on several occasions and also has a thing for Luke. But after they work together on a mission this dislike largely fades.

[[/folder]]

[[folder: Film ]]

* Subverted in ''Film/IronMan2''. Tony Stark ''expects'' this to happen with Pepper and the new aide Natalie Rushman, but the two of them actually get along fine. Pepper takes it as a sign of Tony's arrogance that he'd assume another LoveTriangle would form over him.

[[folder: Literature ]]

* When Wendy joins PeterPan's group, Tinkerbell goes [[YanDere ballistic over this]] and gets Wendy shot by the boys.
* [[PercyJacksonAndTheOlympians Anabeth]] acts this way towards Rachel Elizabeth Dare, [[spoiler: though it's mostly out of jealousy because Percy has clearly fallen from her.]]

[[/folder]]

[[folder: Live Action Television ]]

* Carla toward Dr. Clock in ''{{Scrubs}}''. Mainly because as a psychiatrist Clock was just as good, if not better, at being TheChick and began solving everyone elses problems (while, ironically enough, doing a study into exactly the same sort of workplace hostility while being unaware of Carla's grudge).
* The ''BigBangTheory'': Penny acts like this a couple of times toward an attractive GirlOfTheWeek who will usually be using one of the boys for something. When more permanent members Bernadette and Amy join, though, she's very friendly and bonds with them quickly.
* Averted in an episode of the American ''TheOffice''. When a purse saleswoman comes into the office to sell her products, Michael jokes that Pam will be catty to her since she [Pam] is no longer the hottest woman in the office. Both women are understandably repulsed by Michael's statement.
* On ''Series/StarTrekVoyager'', B'Elanna Torres reacted this way toward Seven of Nine. It was pretty justified.
* As feral on ''MutantX'' are notoriously territorial, Shalimar did not take kindly to another feral joining the team. Per the trope, the new girl was a joy bringer everyone else liked. Worse, Shalimar was ordered to stay at Home Base due to an injury but was normally the I Can Still Fight type without two layers of jealousy for extra motivation. It turned out the new feral was even more territorial. [[spoiler: She staged the accident that injured Shalimar then joined the team to finish her off.]]
* Chiana in ''{{Series/Farscape}}'' tolerated Aeryn, even seeing her as something like a sister (Aeryn was also on the ship before Chiana was) but reacted this way toward both Jool and Sikozu when they came aboard.
* An episode of ''Series/TheBrothersGarcia'' had Carlos and Lorenna trying to join a band. The girl in the band (aptly named "Diva") protested against Lorenna joining because she wanted to be the only girl.
* This is ''Series/BuffyTheVampireSlayer'''s initial reaction to Faith's arrival. There are female Scoobies, but none of them is a Slayer. To her credit Buffy gets over this issue quickly, which is just as well because Faith [[SlowlySlippingIntoEvil has some issues of her own]].
* Lampshaded in ''RedCap'', and put down to the instinctive need of a woman to remove a female rival. When Jo complains this is sexist, her male partner says he'll stop having this belief when women stop proving him right.
* Kate from ''Series/RobinHood'' is in the midst of a conversation with Much and Allan in which she declares herself "the girl" of the gang. Seconds later Robin turns up with Isabella in tow. Kate immediately snarls: "what's the reason for ''her''?"

[[folder: Professional Wrestling ]]

* Sharmel was the only woman of the main event mafia. She was rubbed the wrong way by Jenna Morasca buying her way into the group.

[[/folder]]

[[folder: Video Games ]]

* Ashley of ''MassEffect'' is critical toward Liara joining the squad. Though in this case, it was not specifically because Liara was female ([[OneGenderRace ...sort of...]]), but because she was the daughter of a major enemy agent.
* Parodied in FireEmblemElibe. Serra is at first super bitchy to a VERY pretty new member of the group... [[UnsettlingGenderReveal who turned out]] [[DudeLooksLikeALady to be a girly-looking guy.]]

[[/folder]]

[[folder: Web Comic ]]

* An odd variant in ''SomethingPositive:'' [=PeeJee=] joins [[StraightGay Jhim]]'s role-playing group and designs a female character. [[StrawLoser Mike]], who had previously been the only one with a female character, objects to having two in the party. The Dungeon Master, annoyed, declares that something Mike did in their last session has given his character a permanent GenderBender.

[[folder: Web Original ]]

* In ''RedVsBlue'', when Agent Tex first met Sister, she was rather hostile toward Sister, even going so far as to lay down the law in a private conversation (which Sister, who is one of the {{Cloudcuckoolander}}s of the series, mistook as "you know, girl stuff").
* Parodied by WebVideo/TheNostalgiaChick. She's TheLadette who doesn't know what a ChickFlick is at first and had a whole mini-arc about not wanting to do just girly movies anymore, but she'll still threaten anyone who dares go into her area of female nostalgia.
* From {{Phelous}}'s review of StayAlive: "I'm jealous of her cause I'm a girl."

[[/folder]]

[[folder: Western Animation ]]

* Averted on ''WesternAnimation/AvatarTheLastAirbender''. Katara and Toph clashed after Toph joined, but this had nothing to do with gender (Katara even liked having another girl around) and everything to do with Toph's standoffish attitude. Plus the fact that the entire Gaang was sleep-deprived at the time kept everyone on edge.
* {{Subverted}} on ''WesternAnimation/YoungJustice.'' [[TheChick M'gann]] actually tried to befriend [[AffirmativeActionGirl Artemis]], but the latter ignored the her efforts and openly oggled {{Superboy}}, M'ggan's crush. M'gann was clearly aggravated, but after some light bickering, decided to keep being friendly anyway. Sure enough the two become close friends. Also {{Averted}} later when {{Zatanna}} and then [[{{Icon}} Rocket]] show up.
* Kimiko from ''WesternAnimation/XiaolinShowdown'' reacted poorly to the addition of the mermaid Dyris to the team, mainly because Dyris had no problem flirting with the boys to get them to do things for her. Then Daeris taught Kimiko the same trick and they became great friends...but it was discovered later that Daeris was actually evil.
* [[LampshadeHanging Lampshaded]] in the quote above from the ''Star Wars'' parody episode in ''WesternAnimation/FamilyGuy''.
** In the episode "Forget-Me-Not" [[spoiler:Stewie puts Peter, Brian, Joe and Quagmire in a simulation where they all have amnesia and are the only people around just to see what would happen. Aside from [[ItMakesSenseInContext a misunderstanding that leads the others to believe Peter destroyed everyone else on Earth]] they get along fairly well. In the end we see Stewie has done the same thing with Meg, Lois and Bonnie. They started clawing at each other's throats after just a few minutes.]]
* Inverted in an episode of ''TheSimpsons'' where Lisa tries to pull off a JackieRobinsonStory and announces she's joining the football team. Only when she gets there she finds out there's three other girls on the team already and the coach is welcoming. Enraged she can't be the only girl on the team (or protest the use of pigskin footballs since they're entirely synthetic and the producing company donates to charity) she runs off crying.
* Boom-Boom/Tabitha is the only girl in the Brotherhood house in ''XMenEvolution'' and when [[spoiler: Mystique]] arrives back she leaves saying "too many girls in this house". Then again, Boom-Boom tended to get along well with ''other'' girls as proved by her RomanticTwoGirlFriendship with Amara, and she never really ''fit'' in the Brotherhood too well. [[spoiler: And considering the stuff Mystique did later...]]
* ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'': One episode featured a tribe of [[TheSmurfs Smurf]] [[{{Expy}} expies]] and Grim tried to capture them. One of his attempts consisted on disguising himself as a female of their species, resulting on him getting a beating from ''their'' Smurfette.
