[[caption-width-right:250:[[VideoGame/MarioAndLuigi Let's-a go!]]]]

Blood siblings of either gender working together as equal partners. Their business often involves ass-kicking, in which case they are likely to be BashBrothers or SmashSisters as well. The easiest way to tell that a sibling duo fits this trope is when they are most commonly referred as "the ''Surname'' brothers" or "the ''Surname'' sisters".

BrotherSisterTeam is a gender-specific subtrope. Related tropes are BadassFamily (for when the whole clan is in on the ass-kicking), SuperFamilyTeam (when the whole clan has superpowers), UnrelatedBrothers (a Sibling Team in professional wrestling - who aren't actually related), and WonderTwinPowers (for twins with superpowers that only work in concert). Contrast CainAndAbel.



[[folder:Anime and Manga]]
* Anita King, Maggie Mui, Michelle Cheung a.k.a. The Paper Sisters in ''RODTheTV''.
* The Elric brothers from ''Manga/FullmetalAlchemist''. They are state alchemists. Even if Al is not officially a state alchemist, they are working together as equal partners on both government missions and their personal quest for the Philosopher's Stone.
** Also the homunculi are all brothers and sisters.
** Also the [[spoiler: Slicer Brothers]]
* Xia Yu sisters from ''LightNovel/FullMetalPanic'': assassins/spies. Also, CreepyTwins.
* Kouji and Tetsuya from ''Anime/MazingerZ'' and ''Anime/GreatMazinger'' are adoptive brothers and HumongousMecha pilots. When they are actually fighting their enemy instead of each other, they are a force to be reckoned with.
** Tetsuya and Jun from ''GreatMazinger'' are also adoptive siblings. They overlap this trope with BattleCouple.
** Duke and Maria from ''UFORoboGrendizer''.
* The Thompson Sisters ([[MultipleReferencePun possibly named]] for both the [[http://en.wikipedia.org/wiki/Thompson_submachine_gun machine gun]] and the [[http://en.wikipedia.org/wiki/Thompson_Twins Thompson Twins]]) from ''Manga/SoulEater''. In their backstory they were criminals, until [[MuggingTheMonster they met]] [[{{Shinigami}} Death The Kid]] and became his [[EmpathicWeapon partners]].
** Recent developments ''might'' see Liz and Patti working together as meister and Weapon, as Kid is currently imprisoned by Noah.
*** Confirmed in the Salvage arc. Patti is shaping up to be a ''menace'' as Liz's meister.
* ''Manga/{{InuYasha}}'' and his half-brother Sesshoumaru do this several times later in the manga against [[BigBad Naraku]].
* [[OnlyOneName Gaara, Kankuro, and Temari]] of ''Manga/{{Naruto}}'', who are sometimes called the [[FanNickname Sand Siblings]] by the fandom, after their hometown. Early on in the series, they were actually closer to a deconstruction of this trope; Temari and Kankuro were both out right terrified of Gaara and only followed him out of a mix of obligation and fear. It isn't until post TimeSkip that they start following the spirit of this trope.
** When [[spoiler: Sasuke and Itachi meet again after [[ZombieApocalypse Edo Tensei]] brought the latter back,]] the two team up against Kabuto. Needless to say, it was a ''CrowningMomentOfAwesome''.
* [=N2R=] from ''MagicalGirlLyricalNanoha'', a unit made up of four of the [[spoiler:Nakajima]] Sisters, namely [[spoiler: [[HeelFaceTurn Nove, Wendi, Dieci, and Cinque]]]].
** All twelve Numbers are sisters and a BadassFamily and usually fight in teams. Uno was the MissionControl sister who is out of combat, and Sein was usually the back-up sister who helped the others if they are in trouble. Some of them formed duos, like Nove and Wendi, Quattro and Dieci, Otto and Deed, and Tre and Sette, but a third sister can join them, like Deed joined Nove and Wendi during the GrandFinale. Shortly before, there were three trios, Wendi, Otto and Deed, Tre, Sette and Nove, and Quattro, Dieci and Sein. Cinque usually has no regular partners and can fight alone, but she gave a villainous YouShallNotPass to protect her sisters Nove and Wendi, and she was in a team with Tre and Quattro eight years before the start of the season. The only Number who worked alone was Due, because she was an undercover agent in secret missions, and the only sister who had contact with her was Uno.
** Also, the Liese Twins from ''A's'', although they are twin familiars rather than a real family.
** Erio and Caro are the adopted variant, and they never fight without the other until in ''[=ViVid=]''.
* [[TheStoic Natsumi]] and [[BigEater Kurumi]] in the ''[[RanmaOneHalf Ranma 1/2]]'' OAV, ''The One To Carry On.'' The former uses a [[ImprobableWeaponUser rug beater]] to project [[RazorWind razor-sharp]] [[AnIcePerson freezing]] winds, while the other uses a [[ImprobableWeaponUser hair ribbon several yards long]] to channel [[PlayingWithFire burning]] [[BattleAura ki]]. The two sisters even have a FinishingMove CombinationAttack that uses both aspects to blast their enemies away.
** From the late manga, the sisters Pink and Link, who nearly poisoned the entire town.
** In the anime, Shampoo's childhood friends Rinrin and Ranran.
** From the first [[TheMovie movie]], the brothers Daikokusei and Daihakusei of the Seven Lucky Gods.
** As a note, the three previous SiblingTeams are all twins. Seems like you can't be twins in this series without being part of a battle team.
* ''{{Oishinbo}}'': The brothers in the Ramen and Gyoza volume.
* The Hitachiin brothers from ''OuranHighSchoolHostClub'' are more or less inseparable twins and often partners in crime. They've also been shown beating up punks together.
* Prowl, Sideswipe, and X-Brawn in ''Anime/TransformersRobotsInDisguise''.
* The Frost Brothers of ''[[Anime/AfterWarGundamX Gundam X]]'' are twins with a PsychicLink that enables them to communicate telepathically no matter how far away from each other they are.
** Franchise/{{Gundam}} has more. There's [[Anime/MobileSuitGundam The Zabis]], [[spoiler:[[Anime/MobileFighterGGundam Domon and Kyoji]], although the latter is just a clone of the former's brother]], [[Anime/MobileSuitGundamSeed Kira and Cagali]] and [[Anime/MobileSuitGundam00 Team Trinity]].
* ''Manga/FairyTail'' gives us 'Demon' Mirajane, [[GentleGiant Elfman]], and Lisanna, but the team presumably breaks apart with the latter's death and Mirajane's retirement to TeamMom.
** The [[spoiler:[[SummonMagic Stellar Spirits]] Gemini]] are an example of WonderTwinPowers.
* Ikki and Shun from ''SaintSeiya'' at first started off as CainAndAbel. Finally in the last movie, Tenkai Hen~ Overture, they finally worked together.
** If you go by the manga, you could say that this had been happening for a long time since all the bronze Saints are half brothers with Shun and Ikki being the only full-brothers of the group.
* Panty and Stocking from Anime/PantyAndStockingWithGarterbelt
* The Kongo Twins of {{Eyeshield 21}}, though Agon gets far more attention then Unsui. There's also the Gonzales brothers of the Nasa Aliens.
* The Pichu Brothers in the ''Anime/{{Pokemon}}'' anime.
* ''{{Magikano}}''
* The Borden Twins in ''[[AkahoriGedouHourRabuge Gedou Otome Tail]]''.
* The eponymous characters from Chinese anime GourdBrothers. Seven brothers born from seven gourds on the same vine, each have one color from the rainbow. Rainbow...
* The characters Ace and Luffy for {{One Piece}},[[spoiler: though not biological brothers, think of themselves as siblings, and ]] are very close. They seem to be able to predict each other's moves, and from seeing them battle together in the Marineford War, (and from the filler episodes) it's known they have been fighting together for years. [[spoiler: They also shared this bond with their other adopted brother, Sabo.]]
** There are also the [=DeCalvan=] Brothers, a pair of pirate captains and two of Whitebeard's most trusted men; and Bobby and Kelly Funk, bounty hunters who can defeat supernova-level pirates. (The latter pair is named after Terry Funk and Dory Funk Jr., as seen below.)
* Though they started out as deadly enemies that didn't know their true relationship, [[spoiler:Ryuko Matoi and Satsuki Kiryuin]] from ''Anime/KillLaKill'' eventually join forces and blossom into one of these.

* ComicBook/SpiderGirl plays with this a lot. Fitting for a 'verse made up of [[LegacyHero Legacy Heroes]].
** Crazy Eight and Funny Face, a villainous example. [[spoiler: [[AlasPoorVillain Until Crazy Eight's death.]]]] Their boss is their mother, Angel Face.
*** May also teams up with two [[AnnoyingYoungerSibling annoying younger kids]] in spider costumes, but she's not really related to either of them.
**** However, there is [[spoiler: [[CloningBlues her clone April]]]] and [[spoiler: [[AloofBigBrother cousin Darkdevil]]]], both of whom she's worked with.
* The Brothers Grimm also fulfill the role as well, as villains, of course.
* Hawk and Dove, in regards to both the original Hall Brothers (Hank and Don) and the Granger Sisters (Holly and Dawn).
* Comicbook/TheFantasticFour consist of the Invisible Woman, her younger brother, the Human Torch. Also Sue's husband, Mr. Fantastic, and former beau, the Thing. In the next generation there's Sue's children, Franklin and Valeria.
* During the rare periods when they're both alive, sane and in the same reality, Northstar and Aurora of ComicBook/AlphaFlight serve as a sibling team.
* Cyclops and Havok of the ComicBook/XMen have attempted this on occasion. It never lasts long.
** Siblings rarely seem to work together as teams in the X-books generally, that also goes for Colossus and Magik, for Cannonball, Husk and the other Guthrie kids, and for Karma and her late brother Tran. Professor X and his step-brother Juggernaut even wound up as arch-enemies, and his "sister"[[note]]Basically, we all have an EnemyWithin that we must fight against for the right to be born. Xavier's was badass enough to create its own body from its host's DNA, and grow into a female version of the Prof.[[/note]] Cassandra Nova is the X-Men's ''worst nightmare.''
* Joe, William, Jack and Averell Dalton in ''ComicBook/LuckyLuke''.
* The Double Dare sisters from ''{{Nightwing}}''.
* ''PowerPack'': Four siblings--two boys and two girls.
* The ''ComicBook/{{Batman}}'' comics seem to be trying to get some mileage out of the fact that Bruce Wayne has three adopted sons, a biological son, an alternate universe biological daughter, and (before the New 52 benched her) an adopted daughter:
** After Bruce Wayne's "death," the new Batman and Robin were brothers by adoption Dick Grayson and Damian Wayne.
** ''Franchise/{{Batman}}: Gates of Gotham'' is built on this trope, with the sibling dynamic between Batman, Robin, Red Robin, and Black Bat juxtaposed against the sibling dynamic of the Gates brothers in the back story.
** The ''War of the Robins'' arc of the rebooted ''Batman and Robin'' ends with a team up of the four Robin brothers.
** ''RedHoodAndTheOutlaws'' and ''ComicBook/TeenTitans'' were both rebooted by Scott Lobdell, and he seems to have taken the opportunity to establish that Jason Todd and Tim Drake, while still having some fundamental disagreements about things like killing, have a degree of respect for each other and share information.

* An odd case in ''FanFic/DungeonKeeperAmi''. [[BadAssBookWorm Ami]] and [[ActionGirl Tiger]], who are not sisters, siblings, blood relations, or of the same ''species''. Magical misshap, however, has made them similar in both appearence and mannerism. Later, Tiger is formally adopted into the Mizuno family, playing this trope straighter.
* FanFic/PrettyCurePerfumePreppy: Chloe/Cure Rosa and Chiarra/Cure Vanilla are sisters.
* The ''FanFic/HarmonysWarriors'' series has a side story featuring Pinkie Pie (a spy in this universe) going on a mission with her sister and fellow spy Marble. [[spoiler: It also seems that when [[JekyllAndHyde Pinkamena was the dominant personality]], she tended to do assassin jobs with Limestone.]]
* ''[[FanFic/MLPNextGenerationKnowFear MLP Next Generation: Know Fear!]]'' has Lazarus and Lara, the griffon brother and sister who serve as [[CoDragons Shadow Wing's]] chief [[DeepCoverAgent Pretender agents]].
* The ''MassEffect'' and ''Film/PacificRim'' crossover ''Fanfic/HuntersOfDeath'' has [[BewareTheNiceOnes John]] and [[BloodKnight Jane]] Shepard, usually fighting as a team either on the ground or [[spoiler: in a giant robot as copilots]]

* Joliet Jake and Elwood Blues AKA ''Film/TheBluesBrothers''.
* The creepy albino twins from ''Film/TheMatrix'' sequels.
* The clone army from ''Franchise/StarWars'' could be an example. All the clones grow up together, at any rate, and individual troopers have other troopers that they are especially close to. If not, the four-man commando squads, as in ''VideoGame/StarWarsRepublicCommando'', definitely count.
* Trinity and Bambino, the "right and left hand of TheDevil", respectively, in the ''Film/{{Trinity}}'' series of {{Western}} films (played by Creator/TerenceHill and Creator/BudSpencer, no less). Though Bambino isn't particularly happy about having a brother like that, they make one hell of a team when [[RivalsTeamUp they join forces]].
* [[spoiler: The Borden Twins]] in ''Film/ThePrestige'', who live their lives as one person for the sake of their magic act.
* From ''TransformersRevengeOfTheFallen'', we got the sisters Arcee, Chromia and Elita-1 according to the merchandise. (The movie itself has all three answer to the name, seeming to be one character with three bodies. The comic books split the difference with a [[Franchise/{{X-Men}} Stepford cuckoos]]-type link.
** Skids and Mudflap count too. Two twins who help each other and the Autobots to fight the Deceptions, Simmons against Devastator and help Sam to revive the Matrix... when they don't argue with each other.
* The Bagrov brothers from ''{{Brother}}'', but especially the second movie.
* ''Film/FourBrothers'': Four adopted brothers team up to avenge their mother's death.
* Turk and Virgil Malloy from ''Film/OceansEleven''.
* The Stabbington brothers in ''Disney/{{Tangled}}''.
* Connor and Murphy [=McManus=], ''TheBoondockSaints''.
* Loogie, Laser and Lug from ''{{Shorts}}''.
** Also, Helvetica and Cole.
* In ''Film/PacificRim'', since the co-pilots need to work together well enough to operate the Jaegers, it's understandable to see sibling teams. The original pilots for Gipsy Danger were the brothers Raleigh and Yancy Becket. The Wei Tang Triplets are another example, along with the identical twin brothers of Romeo Blue.
* ''Film/HanselAndGretelWitchHunters'', obviously.
* ''Film/TheRaid2Berandal'' has Hammer Girl and Baseball Bat Man.

* ''Literature/TheHardyBoys''.
* The Weasley Twins and their joke shop from ''Literature/HarryPotter''.
** And in the FinalBattle, [[spoiler:all of the Weasley siblings become a very big version of this trope]].
** Dennis and Colin Creevey.
* The Geste brothers in ''Literature/BeauGeste''.
* If clones count, the so-called [[HandOfThrawn Devist family]], that [[DeepCoverAgent sleeper cell]] of cloned Imperial pilots who become {{Farm Boy}}s, and are insular and ''very'' close because of CloningBlues and FantasticRacism.
** In ''Literature/YoungJediKnights'', the Solo Twins Jacen and Jaina. Once they're out of their teens they quickly stop being together all the time, and, well, we know [[Literature/LegacyOfTheForce how it ended]].
* The Pevensies, the main characters of the first series of books of the ''Literature/ChroniclesOfNarnia'' are brothers and sisters, until Susan and Peter opt out and cousin Eustace comes in.
* Phury and Zsadist from the ''Literature/BlackDaggerBrotherhood''.
* The Brothers Majere in ''Literature/{{Dragonlance}}'', at least, to start with.
* The sons of Fëanor from ''Literature/TheSilmarillion''.
** And Elrond's twin sons, who get very little mention in the ''Literature/LordOfTheRings'' main trilogy.
** In ''Literature/TheHobbit'', Thorin's company is made up of sibling teams of Dwarves.
* Rory and Coco in ''Little League Family.'' Rory catches and Coco pitches. As pitcher-catcher are almost a subteam in baseball, that makes them a literal as well as metaphorical team.
* The ''Literature/SwallowsAndAmazons'' series is mostly about multiple [[SiblingTeam Sibling Crews]] interacting with each other.
* Most Creator/EnidBlyton protagonist groups are at least partially family-based. The Famous Five consist of three siblings, their cousin and her dog, the 'Adventure' group are two pairs of a brother and a sister, etc.
* Teucer and Greater Ajax in ''Literature/TheIliad''. They're half brothers, with Teucer being the bastard.
** Also in the Iliad there's Agamemnon and Menelaus, and on the Trojan side most of Priam's sons.
* Georgia and Shaun Mason in Mira Grant's ''[[Literature/{{Newsflesh}} Feed]]'' are adopted, but every bit as close as blood siblings (they don't like to be apart, ever). They work together on their blog network and watch each other's backs when they go into infected zones.
* Monza and Benna in Joe Abercrombie's ''Best Served Cold'' make a very efficient SiblingTeam -- he's the people person, she's the one who fights. Together, they lead a band of mercenaries. It's implied that they are [[IncestSubtext closer than most siblings]].
* [[spoiler:Half-brothers Harry Dresden]] and Thomas Raith in ''Literature/TheDresdenFiles'', [[spoiler:wizard]] and vampire respectively.
* Niko and ''CalLeandros''. They even have a monster hunting agency.
* From ''Literature/AWrinkleInTime'', there's Meg and Charles Wallace Murry. Plus Calvin O'Keefe, who just gets pulled along for the ride and isn't related to the Murrys. [[spoiler: Yet, anyway.]]
** Same goes for Sandy and Dennys, the Murry twins in "Many Waters."
* Sabrina and Daphne, the eponymous heroines of ''Literature/TheSistersGrimm''.
* Miles and Mark Vorkosigan in Lois McMaster Bujold's novels.
** And, to a lesser extent, Delia, Martya, Olivia, and Kareen, a/k/a Team Koudelka.
* The maran-Kaiel brothers, Hoemei, Gaet, and Joesai, from ''Literature/CourtshipRite'', discovered in childhood that their strengths complemented each other, and have been a team ever since. They're also part of an ExoticExtendedMarriage.
* The Baudelaire siblings in ''Literature/ASeriesOfUnfortunateEvents''.
* In the ''Literature/SagaOfRagnarLothbrok'', the sons of Aslaug and Ragnar Lothbrok--Ivar the Boneless, Bjorn Ironside, Hvitserk, and Sigurd Snake-in-the-Eye--make a glorious career as sea-raiders and conquerors acting as a team. In fact, they are always victorious when they fight by side, but every time they do not all stand together they suffer a defeat.

[[folder:Live-Action TV]]
* Brothers A.J. and Rick from ''Series/SimonAndSimon''.
* The Winchester brothers from ''Series/{{Supernatural}}''.
* ''GreenAcres'' had the Monroe Brothers (Alf & Ralph): general contractors. Alf was a man, Ralph was a woman.
* The Halliwell sisters (a trio) from ''Series/{{Charmed}}''.
* Don and Charlie Eppes work together to pursue evildoers on ''{{Numb3rs}}''. Don is an FBI agent and Charlie is a SmartGuy math consultant.
* Justin, Alex and Max in ''WizardsOfWaverlyPlace''.
* Damon and Stefan Salvatore occasionally team up on ''TheVampireDiaries''.
* Hank and Evan in ''RoyalPains''.
* ''Series/{{Frasier}}'' and Niles Crane automatically team up for anything; from schemes to snag Frasier a date to elaborate, convoluted escapades that end up with them both being accidentally arrested for murder. The fact that they meet at least once a day to complain about their problems and beg the other to help them out contributes to this greatly, while neither the fact that their SiblingRivalry frequently interferes with their teamwork, nor several dozen chewing-outs from their father for blowing things, has never stopped them.
* From ''Franchise/SuperSentai'':
** Geki, [=Tyranno Ranger=] and his older brother Burai, [=Dragon Ranger=] from Series/KyoryuSentaiZyuranger.
** ''Series/SeijuuSentaiGingaman'' with Ryouma, [=GingaRed=], and Hyuga, the Black Knight.
** ''Series/RescueSentaiGoGoFive'', whose team is also made up entirely of five siblings, with their father as the commander. The bad guys except for Pierre (who predates all of the children) are also siblings, with the BigBad their mother!
** The Gouraigers (Ikkou and Isshu Kasumi) from ''Series/NinpuuSentaiHurricaneger''
** [=GekiBlue=] and [=GekiViolet=] (Retsu and Gou Fukami) from ''Series/JukenSentaiGekiranger''. Not carried over to ''Series/PowerRangersJungleFury'' because Theo and RJ as siblings...?
** The Hoshikawas of ''Series/ChikyuuSentaiFiveman'' were the first five-sibling team, before either ''[=GoGoFive=]'' or ''Magiranger''.
* ''PowerRangers'' never has an ''all-''sibling team, because that would result in MonochromeCasting and PR always has a multiracial team. However, two members of teams have been siblings on a humber of occasions:
** ''Series/PowerRangersLostGalaxy'': Leo, the Red Ranger, and Mike, the Magna Defender, [[spoiler: or so it seems at first. But it's complicated.]] Eventually, [[spoiler: played straight after the original Magna Defender dies and Mike, whom he'd merged with, gets to TakeUpMySword.]]
** ''Series/PowerRangersLightspeedRescue'' has Dana the Pink Ranger and Ryan the ''PowerRangers''-exclusive Titanium Ranger. The commander is their dad, as in Go Go V. With the bad guys, only one is the son of Queen Bansheera.
** The Thunder Rangers (Blake and Hunter Bradley) from ''Series/PowerRangersNinjaStorm''. (The two were both ''adopted'' by the Bradleys, but that doesn't matter in the slightest.)
** ''Series/PowerRangersMysticForce'' doesn't have Magiranger's all-sibling team, but keeps the family dynamic alive with sisters Vida and Madison, the Pink and Blue Rangers. [[spoiler: And Nick's whole LukeIAmYourFather situation, but that's neither here nor there.]]
** Twin siblings Gem and Gemma are the Gold and Silver Rangers in ''Series/PowerRangersRPM''.
** Subverted way back in ''Series/PowerRangersZeo'': It's ''heavily implied'' that Tommy's half-brother David is the Gold Ranger. [[RedHerring He isn't.]] It's also teased that he will assume the powers. He doesn't.
* Elsewhere in the spandex vs. PeopleInRubberSuits genre, ''Series/KamenRiderDragonKnight'' has the villainous Cho brothers, better known as Kamen Riders Axe and Spear. [[spoiler: this leads to Axe going on a revenge kick once Spear is eliminated.]] Presumably, this goes for their mirror world counterparts as well.
* ''Series/TheAmazingRace'' has one or two of these per season.
* ''Minutemen'' The MadeForTVMovie features a team of just brothers.
* DG and Azkadelia in ''Series/TinMan''
* The 1985 Tokusatsu series, ''Kyodai Ken Byclosser''. The eponymous heroes are sibling team consisting of two brothers, Ken and Gin.
* Half-sisters Morgana and Morgause from ''Series/{{Merlin}}''. An {{aversion}} with Morgana and Arthur, as by the time they realize they are half-siblings, they are estranged.
* Gunther and Tinka from ''ShakeItUp''.
* The three Twist kids in ''RoundTheTwist'' frequently team up to solve the secret to the latest supernatural event in [[QuirkyTown Port Niranda]], although in some stories only one character is caught up in the weird goings-on.
* ''Series/{{Thunderbirds}}'': The five Tracy-brothers (Scott, Virgil, John, Gordon and Alan), and their TeamDad (Jeff).
* ''Series/SleepyHollow'' has Abbie and Jenny Mills
* ''Series/DancingWithTheStars'' had two sets in the Houghs (Derek and Julianne) and the Chmerkovskiys (Maks and Val).

Musical siblings are common in rock bands and vocal/R&B groups. Family-based groups are more common in country and older vocal groups. Some examples (more can be seen at BandOfRelatives):

Later on, another brother, bassist Matt Porcaro (a founding member replaced before the recording of their SelfTitledAlbum by David Hungate, [[ExecutiveMeddling as their label wanted the same band]] that recorded Boz Scaggs' ''Silk Degrees'') joined in the mid-[[TheEighties 1980s]] until retiring as he was suffering from Multiple Sclerosis.
* Music/TheHives - Howlin Pelle Almqvist and Nicholaus Arson are brothers.
* Music/DeBarge

[[folder:Professional Wrestling]]
* The gimmick of identical twins who can win matches because they look so much alike they can [[TwinSwitch switch places in the ring without their opponent realizing it]] is a very common one.
** Ron and Don Harris, who worked both in Wrestling/{{WCW}} and Wrestling/{{WWE}} under various gimmicks including The Blu Brothers, the Disciples of Apocalypse, and Creative Control.
** The Wrestling/BellaTwins Nikki and Brie
** The Shane Twins, best known as the Gymini in WWE and [[Website/{{WrestleCrap}} The]] [[GagPenis Johnsons]] in early Wrestling/{{TNA}}.
** Shu and Kei Sato, two Japanese wrestlers whose gimmick changed from pop singing sailors to Hindu occultists..
** [[Wrestling/TheWorldsGreatestTagTeam Charlie Haas]] and his brother Russ, although Russ sadly passed away at a young age while in OVW
** The Briscoe Brothers in their early evil redneck days

* Dory Funk Jr and his brother [[Wrestling/TerryFunk Terry]]

[[folder:Religion and Mythology]]
* A common trope in pre-Columbian America involves twins doing this.
* In ClassicalMythology:
** Castor and Polydeuces, twin half-brothers. Eventually turned into the (Greek version of) the constellation Gemini.
** Amphion and Zethos, twin sons of Zeus and Antiope.
** Idas and Lynceus, inseparable sons of Aphareus of Messene and his wife Arene, although it was believed that Idas' real father was Poseidon.
** Heracles and his nephew Iolaos.

[[folder:Tabletop Games]]
* Naestra and Arahan, the twin Wood Elf sisters in ''WarhammerFantasy'' who shoot people with their longbows from dragonback.
** Technically Naestra and Arahan are two mystically separated aspects of the same elf, rather than sisters, but they behave like sisters for all intents and purposes.
* ''TabletopGame/WarhammerFantasy'' also has the High Elf identical twins Tyrion and Teclis, who often fight together, especially in times of great peril, but just as often operate apart.
* [[TabletopGame/{{Warhammer 40000}} Eldar]] [[GlassCannon Viper]] teams consist of psychically-linked twin-sibling teams for better coordination.
** An Eldar Wraithknight is a very special case of this, as it is piloted by a team consisting of identical twins, one living and the other dead.
** Primarchs [[CreepyTwins Alpharius and Omegon]] led the Alpha Legion of Space Marines together throughout the Great Crusade (and might still be in charge despite one or the other being declared dead multiple times).
* In ''MagicTheGathering'', the planeswalker Ajani Goldmane and his late brother J'zall were a nigh unbeatable team. J'zall was their tribe's leader and strongest warrior, and Ajani's special brand of magic could make him even stronger.
* Kamaitachi, Kamanitachi and Kamamitachi of the Yosenju archetype in the ''TabletopGame/YuGiOh TCG'' are anthropomorphic weasel brothers with a kamaitachi theme

[[folder:Video Games]]
* Lt. David "Hesh" Walker and Sgt. Logan Walker from "VideoGame/CallofDutyGhosts".
** Their father also serves as their commanding officer at times, making them a
* The [=McCall=] brothers from ''VideoGame/CallOfJuarezBoundInBlood'': adventurers and robbers.
* The Chang brothers from ''VampireBloodlines'': guardians of Ankaran Sarcophagus.
* The Kasuga Family of ''VideoGame/ArcanaHeart'', four {{Miko}} sisters that fight together with Maori as head.
* Mario and Luigi, the SuperMarioBros.
* [[SpiritedCompetitor Terry]] and [[McNinja Andy]], the [[FatalFury Bogard]] [[KingOfFighters Brothers]].
* The Komodo Brothers from the ''Franchise/CrashBandicoot'' series, though they only appeared together in ''Videogame/CrashBandicoot2CortexStrikesBack'' and ''Videogame/CrashBash'', while Joe went it alone in ''Videogame/CrashTeamRacing''. Neither has been seen since.
* From ''VideoGame/FinalFantasyX'', we have the Summoner Issaru, along with his two younger brothers as his Guardians.
* J.C. and Paul Denton in ''VideoGame/DeusEx'' and [[VideoGame/DeusExInvisibleWar its sequel]].
* Billy and Jimmy Lee, [[VideoGame/DoubleDragon the Double Dragons]].
** In the arcade version of ''Double Dragon 3'', this trope is invoked literally by having the playable characters divided into four groups of different sibling teams (the Lee Bros., the Oyama Bros., the Urquidez Bros., and the Chin Bros.), essentially an excuse to [[ColorCodedMultiplayer allow more than one player to control the same character.]]
** Billy and Jimmy's counterpart in ''RiverCityRansom'' were named Randy and Andy. Their [[DubNameChange counterparts]] in the [[KunioKun Kunio-kun]] series were named Ryūichi and Ryūji Hattori.
* Oscar and Emile Bielert from ''VideoGame/ValkyriaChronicles'', both [[FriendlySniper snipers]].
* Yun and Yang from ''VideoGame/StreetFighterIII''.

* Sisters Faris and Lenna from ''VideoGame/FinalFantasyV''.
* Edgar and Sabin Figaro from ''VideoGame/FinalFantasyVI''. Royal siblings, no less. Having them in the same team together is only mandatory for one very brief period, but their most significant scenes involve both of them. Amusingly, while Sabin can be recruited before Edgar in the [[AfterTheEnd World of Ruin]], but because he's optional, the (mandatory) scenes for Edgar's recruitment leave him mostly silent. You'd think he'd have some comments about his brother's PaperThinDisguise, but no.
* Hisui and Kohaku Hearts from ''VideoGame/TalesOfHearts''
* ''VideoGame/TalesOfGraces'': Asbel Lhant and Hubert Ozwell.
* ''VideoGame/DragonAgeII'': Hawke and his or her twin siblings are quite capable in battle, and the surviving twin will always have a class that compliments Hawke's, also making them SwordAndSorcerer.
* ''VideoGame/FinalFantasyDimensions'' has two sets of siblings, Diana + Aigis and Alba + Dusk. For most of the game the siblings are separated by the dimensional rift, but they can all potentially be on the same team in the endgame.
* ''VideoGame/{{Xenoblade}}'': [[spoiler: Dunban and Fiora.]]
* ''VideoGame/StarWarsRepublicCommando'': Every Commando squad, being clones.
* ''VideoGame/ASuperMarioThing'' and its spin-offs have Demo and Iris, the two cycloptic demon sisters and main characters.
* ''VideoGame/PokemonRubyAndSapphire'' has Tate and Liza, the BrotherSisterTeam of Gym Leaders from Mossdeep City. Some of the trainer classes you can encounter throughout the series are also siblings, like the Twins, Sis and Bro, and the Mysterious Sisters.

* Kavra and Khevresh from ''WayfarersMoon''. This does not end well when [[spoiler: Khevresh is killed by Iri and Kavra goes for revenge]].
* [[BlowYouAway Taffe]] and [[MakingASplash Larima]] from ''Webcomic/{{Pacificators}}''. They're awfully protective of each other, as they're the [[DeathByOriginStory only family they have left.]]

** Real life example too as they both worked together on nature shows ''KrattsCreatures'' and ''{{Zoboomafoo}}''.

* James Brothers: Jesse and Frank James, famous American outlaws and leaders of the [[http://en.wikipedia.org/wiki/James-Younger_Gang James-Younger Gang]].
** The James brothers seem to have made a habit out of working with sets of brothers as well. The James-Younger gang included the four Younger brothers: Cole, Jim, John, and Bob. Later the James brothers worked with the Ford brothers: Charlie and Robert/Bob. That didn't work out so well for Jesse though (or, for that matter, the Fords).
** The Youngers were also cousins to the Dalton brothers, Bob, Gratton and Emmett.
* [[http://en.wikipedia.org/wiki/Kelly_Gang The Kelly Gang]] consisting of brothers Ned and Dan (and two other close friends of the family) were part of an Australian outlaw gang (referred to as 'bushrangers').

His bother Wilhelm was also a member of said group. They were such a successful team they aroused antipathy in other members of the section. As a result, Wilhelm was transferred away from his brother.
* Manfred (the Red Baron) and Lothar von Richthofen. Both served in the same squadron, and were amongst the highest scoring aces of WWI.
* Andrew and Allen Cunningham in UsefulNotes/WorldWarII . Andrew in the Royal Navy and Allen in the British Army. Andrew was a genuine FourStarBadass. Allen was at first thought to be so because of his conquest of Ethiopia from the Italians. But he went down in history as a might-have-been because he lost his nerve [[OvershadowedByAwesome facing Erwin Rommel]].
* The Sedin twins, Henrik and Daniel, of the NationalHockeyLeague's Vancouver Canucks. They are decent players on their own, but when they're on the ice together, look the fuck out.
** Before the Sedins, there were the Sutters, ''six'' brothers who all played in the NHL. Brent and Duane were teammates on the New York Islanders, while twins Rich and Ron played together for the Philadelphia Flyers ''and'' St. Louis Blues.
** Now there is another family with many hockey players, the Staals. Three of them are on the same team, the Carolina Hurricanes (where the eldest, Eric, won the StanleyCup in 2006; in 2012, he was joined by Jordan, who had been champion with the Pittsburgh Penguins in 2009, and the following year came the youngest, Jared), and the remaining, Marc, is with the New York Rangers.

-->It’s some sort of hockey rule that every set of brothers has to play on the same team for some reason. The Staals, the Sedins, the Stastnys, the Bures, the Schenns — everyone gets to play together at some point. It’s kind of like Little League.
