->''"I gotcha back, you watch my front."''
-->-- '''[[Creator/SamuelLJackson Gin Rummy]]''', ''WesternAnimation/TheBoondocks''

Think about your closest friends. If you know them well enough, you also know their strengths and weaknesses. You know how they think, how they react, how they tick. You trust them to know the same about you, too. You might even trust them enough to let them fix your car--[[DrivesLikeCrazy but not drive it. Hell would freeze over before you let them drive it.]]

In action oriented stories, two characters who are friends will work with each other during combat. Often this will present the image of BackToBackBadasses. If [[BigGuyLittleGuy one person is big and the other short,]] [[ForceAndFinesse the big guy will use brute strength and the short guy will use finesse]]. Maybe the big guy will clasp hands with the short guy [[GrievousHarmWithABody and fling him around as though he was a weapon.]] Or the big guy will use the [[LivingWeapon short guy]] [[FastballSpecial as a projectile.]]

No matter what, they will fight in tandem. They will watch each other's back. There is something genuinely satisfying about watching the heroes take out a room full of bad guys by working together.

Characters who tend to do this are TheHero and TheLancer because they are {{foil}}s to each other and so their fighting style complements the other. Even a mismatched ActionDuo can be Bash Brothers with enough bonding/training.

It is not uncommon in certain stories to have two separate badasses who come together, spend some time trying to kill each other only to eventually turn their skills onto the hapless enemy [[EnemyMine who happens to piss them both off.]]

If the "brothers" are actually related by blood, it's a SiblingTeam. A combative inversion is FearfulSymmetry. In a fantasy setting, they might be a SwordAndSorcerer. Not to be confused with the [[VideoGame/SuperSmashBros Smash Brothers]] who are, well, [[ExactlyWhatItSaysOnTheTin Super]]. The romantic version is the BattleCouple. And finally, a female duo may overlap with LovelyAngels.

Compare TagTeam, RedOniBlueOni, MovesetClone, and SwordAndSorcerer.

The name comes from the world of sports, where it refers to a pair of great players who end up on the same team. The first use of the term was in UsefulNotes/{{Baseball}}, where Jose Canseco and Mark [=McGwire=] formed a dangerous duo for the late-1980s-early-1990s Oakland A's on account of their incredible (and, as it turned out, steroid-fueled) power hitting. It has since spread to other players and sports. And yes, this trope happens with [[ActionGirl female fighting duos]] as well, in which case we refer to them as Smash Sisters.


[[folder:Anime & Manga]]
* ''Manga/{{Berserk}}'' has a few moments like this in later arcs, with Guts smashing headlong into the MonsterOfTheWeek while Serpico leaps around taking care of the {{Mooks}}.
* ''Manga/{{Bleach}}'':
** While they're not ''as'' close friends as others, one episode had Chad and Uryu facing off against two foes. Originally, they were getting beat up hard. That is, until Uryu opted to [[OpponentSwitch switch opponents]] with Chad, seeing Chad's [[MightyGlacier slow but strong]] style better on Uryu's opponent, and Uryu weak but fast style on Chad's.
** Before the advent of Rukia and TheCallKnowsWhereYouLive and Ichigo turning into this unstoppable level-grinding machine, Ichigo and Chad also went [[BullyHunter bully hunting]] like this. They agreed years ago that if it wasn't okay to get in fights on their own behalves (and being redheaded and half-Mexican, respectively, they're major targets) they would always fight to protect each other. It's very sweet. Chad has spent the last two hundred chapters trying to be strong enough to keep this promise again. [[CantCatchUp No dice]].
** As the Thousand Years Old Blood War advanced, Ichigo and Renji Abarai kinda fell into this trope. The biggest example is towards the end, when Renji explicitely promises to back Ichigo up as thanks for helping him rekindle his bond with Rukia, and immediately keeps his promise as they join a ''very'' complicated final fight that incliudes [[TheEmperor Yhwach]] and [[spoiler: '''Aizen'''.]]
* ''Anime/DragonBallZ'':
** Gohan and Krillin are the best of friends and, particularly during the Saiyan and Namek arcs, a great example of bash brothers (though, ironically, Krillin is close friends with Gohan's father and is more of an extended uncle to Gohan). After the seven year time skip, the next generation of warriors [[HeterosexualLifePartners Goten and Trunks]] are the newest set of bash brothers to the show.
** Goku and Piccolo became this in an EnemyMine situation against both Garlic Jr. and later against Raditz.
** Burter and Jeice are the only members of the Ginyu Force who fight together rather than one-on-one, and have at least one CombinationAttack. Unfortunately for them, their only on-screen fight is against Goku, who's way out of their league.
** [[RedOniBlueOni Goku and Vegeta]] play with this, but mostly in the movies and especially the Majin Buu saga. It's a running theme that they're so [[ChallengeSeeker hyper-competitive]] that their "teamwork" usually amounts to swapping in and out tag-team style, rather than fighting someone two-on-one (no matter the stakes).
** [[BigBadEnsemble Frieza and Cell]] wound up forming one of these after their defeats, training together and teaming up on Goku when he gets trapped in Hell in GT ([[TheWorfEffect not that it helps them at all]]).
** Gohan and Piccolo spend a good chunk of the Tournament of Power as this. While Goku and Vegeta mostly do their own thing and only team up if they run into each other, Gohan and Piccolo make an effort to stick together and prove to be a very effective team.
* In ''Anime/{{Endride}}'', despite their absolutely endless [[VitriolicBestBuds bickering]] and occasional fistfights, Emilio and Shun end up becoming this trope as they fight the best at [[BackToBackBadasses each other's backs]]--perhaps because it keeps them within [[VolleyingInsults insult range]] during battle.
* In ''Manga/{{Gintama}}'', this happens mostly during the serious episodes. Usually, Kagura and Shinpachi team up in the serious story arcs to deal with {{Mooks}} and the occasional [[EliteMooks Elite Mook]].
** The Benizakura Arc has Gintoki and [[strike:Zura]] Katsura in a BackToBackBadasses moment, fighting against [[spoiler: space pirates hired by Takasugi]] and then declaring war on [[spoiler: Takasugi]] with the exact same words and in the exact same manner.
* Kira and Athrun from ''Anime/MobileSuitGundamSEED'' do this several times, coordinating their attacks and defenses to the point of near-telepathy.
** It helps that the Freedom and Justice are designed to work in tandem with each other, thus adding an extra layer to their status as this.
* From ''Manga/HarlemBeat'', we have Naruse-Sawamura duo both in their streetball and highschool team.
* In ''Manga/HunterXHunter'' it was said that two members of the Genei Ryodan (Uvogin and Nobunaga Hazama) had this kind of relationship. They were at their strongest when they fought large groups of enemies together, though Uvogin would never admit it.
* In the second last episode of ''Anime/KotetsushinJeeg'', both Hiroshi Shiba (the original Jeeg pilot) and Kenji Kusanagi (the sequel's new pilot) are finally given the chance to both transform into their respective Super Robots, and what follows is an epic, ''epic'' double-teaming brawl.
* Nagi and his team the Ala Rubra in ''Manga/MahouSenseiNegima'' fought like this. Negi and Kotaro have been developing a style like this since entering the colosseum as a team.
* ''Anime/MazingerZ'' has Kouji and Boss. They begin at odds with each other but quickly they become good friends and fight together; ''Anime/GreatMazinger'' has Tetsuya and boss, and later in the series, Tetsuya and Kouji; ''Anime/UFORoboGrendizer'' gave us Kouji and Duke; And finally ''Anime/{{Mazinkaiser}}'' showed more examples of how devastating Kouji and Tetsuya are when they are fighting together.
* Subverted in ''Manga/{{Naruto}}''. It looks like Naruto and Sasuke are building into this, but then Sasuke pulled a FaceHeelTurn.
** They revisit Naruto and Sasuke becoming this again in the battle with [[spoiler: Obito and this time they succeed.]]
*** [[spoiler: Revisited and taken UpToEleven in the final battle of ''Anime/BorutoNarutoTheMovie''. Made even more awesome by the fact they mostly use physical attacks, and despite Sasuke [[AnArmAndALeg lacking his left arm]], [[HandicappedBadass he never slows down]].]]
** In Shippuden, Naruto has developed into this with Killer B, who is also this with A / the Raikage. It turns out they're not actually related - A [[InvokedTrope adopted Bee]] because he was badass enough for their combat styles to mesh.
** Ino-Shikamaru-Chouji is a better fit. They've been best friends for so long (since before they became ninjas), Chouji is able to pick up Shikamaru's strategies and prepare well before anyone else, Shikamaru knows just how to set up Ino's powers, and likewise Ino knows how to cover Chouji's weak points. By the time of the 4th Ninja World War, the trio's practically invincible.
** The Ino-Shika-Cho trio even extends into their family. It's actually a tradition for three of the current generation to be put into a team together with a Sarutobi as their sensei.
** And more recently, Kinkaku and Ginkaku. The two [[spoiler: dead]] shinobi who [[spoiler: '''survived being eaten by the Kyuubi for two weeks!''']]
* In ''Manga/OnePiece'', Zoro and Sanji are somewhat like this. They may bicker in the midst of battle and occasionally attack each other, but once they work together (as shown in the Davy Jones games), they are near invincible.
** The entirety of the Straw Hat Pirates are very capable at working together against foes. This aspect was heavily portrayed during the events at Thriller Bark and the Sabaody Archipelago.
** Law and Luffy become this trope into the latter part of the Dressrosa saga [[spoiler:With the fight against Doflamingo]].
* ''Manga/RanmaOneHalf'' has a antagonistic version of this as a VillainOfTheWeek arc. [[{{Kawaiiko}} Azusa Shiratori]] and [[HandsomeLech Mikado Sanzenine]] are masters of [[MartialArtsAndCrafts Martial Arts Figure Skating]], a team known as the Golden Pair for their combined skill and excellent teamwork. Outside of combat, however, [[TeethClenchedTeamwork the two don't get on too well]], as Mikado finds Azusa's kleptomania and ditzy antics annoying, while Azusa has the personality of a SpoiledBrat and is quite willing to beat on Mikado if he interferes with her antics (giving back something she stole from a pretty girl, or chasing girls when he should be practicing). In fact, she's ultimately the one who beats Mikado, causing them to lose.
** Perhaps to highlight their BelligerentSexualTension, Ranma and Akane keep swinging between playing this straight and averting it. While they played it perfectly straight in the Martial Arts Figure Skating story, most if not all of their subsequent 'team battles' had them getting in each other's way and forgetting to pay attention to their enemies to squabble with each other (often over the fact Akane is OvershadowedByAwesome compared to Ranma and CantCatchUp, yet refuses to admit this)... though, inevitably, they would pull together (if only after having been beaten once) and manage to pull off a victory, though their opponent would frequently come close to victory by taking advantage of their bickering.
* Kenshin and Sanosuke from ''Manga/RurouniKenshin''.
* Played straight in ''Anime/SoulEater'' with the Resonance or Chain Resonance Links, you want evidence? Watch episode 36.
* Simon and Kamina from ''Anime/TengenToppaGurrenLagann'', and later, Simon and [[spoiler:Viral]].
** Don't forget Jogin and Balinbou.
* Vash and Wolfwood in ''Manga/{{Trigun}}''. Their fighting styles are relatively similar and they have a WideEyedIdealist versus KnightInSourArmour thing going on for [[{{Foil}} contrast]].
* ''Anime/YuGiOh'' had two pairs: The Paradox Brothers from the Duelist Kingdom arc and Lumis/Umbra from the Battle City arc. Joey and Yugi are this in their various tag team duels (heck, even their Dark Magician and Flame Swordsman show signs of it); a major problem in the Lumis/Umbra duel is Yugi and Kaiba's inability to pull this trope off. In the anime at least, Yugi and Kaiba eventually play this straight in their confrontations with both Dartz and Zorc.
* Yusuke and Kuwabara from ''Manga/YuYuHakusho'' were a more heroic version.
** This following upon several years of Kuwabara incessantly returning to challenge Yusuke to fights and getting his clock soundly cleaned. Yusuke has been known to do this with other members of his team, as well. Once very briefly with Hiei.
* Sena and Monta from ''Manga/{{Eyeshield 21}}'' are the best (respectively) runningback and wide receiver in Japan, best friends, and the keys to Deimon's offensive power. Needless to say, some of the Devilbat's best plays involve the two working together.
** Of course, there are also the Ha-Ha Brothers who show signs of this, though they're a triple package. The moves they used in their first game, and continue to use, sink the "bash" part rather well. A more conventional example would be Tetsuma and The Kid of the Wild Gunmen, showing how epic their teamwork was in their first appearance.
** Similar examples would be Taka and Yamato of the Teikoku Alexanders (another runningback/reciever duo), and the lethal three way combo of Takami (quarterback), Shin (linebacker/runningback), and Sakuraba (reciever) of the Ojou White Knights. The last three are especially interesting as Sakuraba and Shin, and Sakuraba and Takami are Bash Brothers by themselves; when their plays begin to intersect it simply becomes ''more'' of a problem for the other team. For a literal example, there's the SiblingTeam of [[JerkJock Agon]] and [[TheUnfavourite Unsui]] of the Shinryuuji Nagas.
** Despite being the leaders on the opposite spectrum for talent, Agon and Hiruma are an effective combination. Agon who runs on pure reaction is complemented by Hiruma who runs on pure mental ability. Despite their hatred for each other, they work extremely well together.
* Ian and Mitchal of ''Anime/HeatGuyJ''.
* In ''Manga/FistOfTheNorthStar'', Kenshiro and Rei, while rescuing Airi and Mamiya from the Fang Clan, have some seriously badass action sequences together. Raiga and Fuga, the SiblingTeam gatekeepers of the Cassandra Prison who pull a glorious HeelFaceTurn and subsequent HeroicSacrifice, also qualify.
* The title characters of ''Anime/TigerAndBunny'' become this once Kotetsu/Wild Tiger successfully wins Barnaby/"Bunny"'s trust in him.
* In ''Manga/AirGear'', the original members of the Sleeping Forest all seem to fight in duos in ways that support each others' styles. Probably part of why they're one of the greatest Storm Rider teams in existence.
* In ''Manga/FullmetalAlchemist'', Alex Luis Armstrong and Sig Curtis (who befriended each other through PecFlex) work together to curb stomp [[TheBrute Sloth]] in a scene that is RatedMForManly.
** This is after Alex and his older sister Olivier got through a very long period of wearing him down; Sig only came in at the end, and the Armstrong team was pretty damn impressive in its own right.
** Ed and Al obviously do this, too. They have a lot of practice fighting together.
** When Ed and Ling or Ed and Greeling are working together, they generally produce shades of this even when not actively engaged in combat. With lots of bickering.
* Every RedOniBlueOni pair in ''Franchise/{{Digimon}}'' [[VitriolicBestBuds eventually]] becomes this, with the relationship extending to their partner Digimon - [[Anime/DigimonAdventure Taichi and Yamato]] (and Agumon and Gabumon), [[Anime/DigimonAdventure02 Daisuke and Ken]] (and V-mon and Wormmon), [[Anime/DigimonFrontier Takuya and Kouji]], and [[Anime/DigimonXrosWars Taiki and Kiriha]] (and Shoutmon and [=MetalGreymon=]). Masaru and Agumon of ''Anime/DigimonSavers'' are a surprisingly rare instance of a Digimon being this with their human partner, being that Masaru is the only ''Digimon'' lead to actively fight Digimon personally.
* ''Manga/TsubasaReservoirChronicle'' gives us [[TeamMom Fay]] and [[TeamDad Kurogane]], starting from their battle with Kishim.
** Though they are more of a BattleCouple, with what is known now.
* ''Manga/KurokoNoBasuke'' gives us Kuroko and Kagami. Often giving them the otp name; "Kagakuro"
* Though this is noted to be rare in ''Anime/PuellaMagiMadokaMagica'', with most girls operating alone, this just makes the rare duos all the more dangerous. Mami and Kyouko were once this, but [[FallenHero broke up]] [[spoiler: after Kyouko's family died]], and Mami's desire to find a new partner drives much of her motivation. By the time of ''[[Anime/PuellaMagiMadokaMagicaTheMovieRebellion Rebellion]]'', Kyouko and Sayaka have become a fairly close pair, often employing {{Combination Attack}}s and apparently living in the same house. In ''[[Manga/PuellaMagiOrikoMagica Oriko Magica]]'', Oriko and Kirika do this whenever Oriko isn't grounded by PowerIncontinence. Fanon typically upgrades all of them into full-on {{Battle Couple}}s.
* Long before Madoka was doing it, ''Anime/PrettyCure'''s most iconic teams were all either this trope or {{Battle Couple}}s depending on who you ask. Black and White in particular occasionally used each other as weapons in the first season; on one occasion two monsters threw them at each other, so the girls locked elbows on impact and torqued their bodies around each other so they both went flying boots-first back the way they came.
* While they start the series off as mortal enemies, [[spoiler:Ryuko and Satsuki]] of ''Anime/KillLaKill'' develop this dynamic when they join forces against [[spoiler:their own mother, Ragyo]]. Bonus points for being [[spoiler:literal Smash Sisters]].
* ''Manga/ShokugekiNoSoma'': Gin and Jouichiro where this during their school days, fighting with [[CookingDuel food]], political influence and brute force to crawl out as the undisputed top dogs out of 1000 highly competitive trainee chefs.

[[folder:Comic Books]]
* Franchise/{{Batman}} and ComicBook/{{Robin}} do this quite often. It was especially common in the live-action Batman series.
** Much less frequently, you get really ''astounding'' sequences with large chunks of the "[[BatFamilyCrossover Bat Family]]" (Batman, ComicBook/{{Batgirl}}, ComicBook/{{Robin}}, ComicBook/{{Nightwing}}, Comicbook/RedRobin and a few more minor ones) fighting side by side.
** Also, our (former) page image...Bats with Franchise/{{Superman}}.
** Examined in the ''World's Finest'' maxiseries; the first time they meet with the explicit purpose of working together, they're at a function as Bruce and Clark when the guest of honor, a world-famous plastic surgeon is kidnapped. They split up and both go after the kidnapper, which so spooks the hostage that he runs out into the street and gets himself killed. When they compare notes they both observe that this happened because they ''didn't'' work together. The rest of the series is about their annual meetings to honor their failure and learn to work together until they're working as a well-oiled machine. [[spoiler:Some of their guilt is mitigated when they learn at the end of the maxiseries that said hostage was actually the surgeon's body double who had kidnapped and replaced the real man after giving him amnesia in an attempt to steal his fortune. The real reason he was so spooked was because he was afraid that Batman and Superman would expose his scheme.]]
%%* {{Comicbook/Aquaman}} and Comicbook/MartianManhunter.
* ComicStrip/ModestyBlaise and [[KnifeNut Willie Garvin]] specialise in this.
%%* ComicBook/IronMan and ComicBook/WarMachine
* In the ComicBook/XMen, Colossus and Wolverine have the "FastballSpecial" (sometimes [[CallingYourAttacks called for]] with "Hey bub... two words"), which basically involves Colossus throwing Wolverine at an opponent. Other characters inside and outside of Marvel have occasionally borrowed the move. Basically any combo of a character with SuperStrength and one with an AbsurdlySharpBlade or six can do this. In the ''extremely'' rare occasions that they're seeing eye to eye, Cyclops and Wolverine can do this quite well, though they end up as RedOniBlueOni much more often.
%%* ComicStrip/MandrakeTheMagician and Lothar.
* ''Comicbook/{{Watchmen}}'': Rorschach and Nite Owl II, in the old days. The bond they forged still lasts.
* Marvel also has [[Comicbook/LukeCageHeroForHire Luke Cage]] and [[ComicBook/ImmortalIronFist Iron Fist]]. [[SaltAndPepper Power Man and Iron Fist]] are perhaps one of Marvel's best examples of this trope in action: Luke is a MadeOfIron BoisterousBruiser and Danny is WeakButSkilled with some elements of LightningBruiser. Ever since they were paired up for roughly two decades worth of comics they were ALWAYS seen together, until Luke got picked as one of Brian Bendis' favorite characters and appeared more often without him. The duo was reunited when Danny joined the Comicbook/NewAvengers, of which Cage had become the leader.
* ComicBook/SpiderMan and ComicBook/{{Daredevil}}. The two have teamed up many times and they are best buddies. It helps that they both share a number of villains. (Their first ever collaboration was against an evil hypnotist who couldn't affect the blind Daredevil but made Spidey beat him up for a while.)
** And their shared enemies the Enforcers featured Ox and Fancy Dan, who would often tag team enemies with their astounding strength and martial arts skills, respectively. Later additions Hammer Harrison and Snake Marston would do much the same.
** For that matter, Spidey and Johnny Storm.
* Marvel's original Bash Brothers, ComicBook/CaptainAmerica and ComicBook/BuckyBarnes.
** Also Captain America and ComicBook/TheFalcon.
** Bucky and the Falcon eventually grow into it, too, during Bucky's run as Captain America.
* Franchise/{{Superman}} and his cousin Comicbook/{{Supergirl}}. Since Supergirl's creation back in the Silver Age they have been partners and fought together.
** In ''Comicbook/KryptonNoMore'' they fight an army of world-conquering aliens.
** In ''Comicbook/LegionOfSuperHeroes'' classic StoryArc ''The Great Darkness Saga'', [[http://2.bp.blogspot.com/_tW3g8zCM6c0/TU20053fQ-I/AAAAAAAABf4/5euaP9-E9ak/s1600/lsh%2B294%2Bsuper%2Bboy%2Bgirl.jpg both Superboy and Supergirl take on]] Comicbook/{{Darkseid}}. ''Darkseid''. And although Superboy is taken out quickly, Supergirl lays a good whupping on the ruler of Apokolips. [[http://bronzeagebabies.blogspot.com.es/2011/02/legion-of-super-heroes-great-darkness.html Reviewed here]].
** In ''Comicbook/WarWorld'' Superman resorts to Supergirl to help him bring Mongul and Warworld down. The two of them fight together and manage destroy the massive war machine.
--->'''Superman:''' Now there isn't a thing in all the universe that can stop him!\\
'''Supergirl:''' Well, I know two "things" who are certainly gonna try!
** In ''[[Comicbook/{{Supergirl 1982}} Supergirl Volume 2]]'' #21, Supergirl and Superman fight Kryptonite Man together.
* Comicbook/GreenArrow and Franchise/GreenLantern.
** Also Franchise/GreenLantern Kyle Rayner and Franchise/GreenLantern Guy Gardner, or occasionally other GL pairings.
* ComicBook/QuantumAndWoody
* Marvel's Zapata Brothers are Mexican wrestlers, so it's only to be expected that they have an array of team-up moves. They also enjoy high-fiving during melees and switching out as if they were in a tag team match.
* ''SamAndMaxFreelancePolice'' aren't fighters per se, but if there are doors to bust down and bad guys with lead deficiency, they'll deliver the damage together. Moreso in the comics, but they get rare moments in the video games, too.
* ComicBook/{{Asterix}} and Obelix always team up together to beat up a bunch of Roman soldiers. While sometimes they have the village to fight with them, most of the time it's the two of them ([[TeamPet and Dogmatix]]).
* ComicBook/BoosterGold and ComicBook/BlueBeetle. The amount of HoYay fanart of them is ''staggering''.
* In ''ComicBook/{{Legacy}}'', Cade Skywalker and Jariah Syn are this throughout his pirate and bounty hunting days, though on Jedi stuff Cade's fellow Padawan Shado Vao sometimes takes the role. Imperial Knights Antares Draco and Ganner Krieg almost always fight as an in-sync duo.
* ComicBook/{{Cable}} & ComicBook/{{Deadpool}}, at least in the series titled that way.
* Franchise/WonderWoman and her younger sister, Donna Troy are this, and the two of them are building a similar relationship with Cassie Sandsmark, the second ComicBook/WonderGirl. Donna and Dick Grayson are often written this way in the pages of ''ComicBook/TeenTitans''.
* [[ComicBook/TheMightyThor Thor]] and ComicBook/BetaRayBill
* Gamora and [[ComicBook/AngelaMarvelComics Angela]] are SmashSisters in ''ComicBook/GuardiansOfTheGalaxy''.
** From the same series: Rocket Racoon, a [[MoreDakka gun-toting]] [[NinjaPirateZombieRobot genetically-modified cybernetically-enhanced]] [[AnimalSuperhero raccoon]]; and Groot, a [[TheBigGuy lumbering]] [[PlantAliens tree monster]] who suffers from a bad case of PokemonSpeak. This is particularly true in [[Film/GuardiansOfTheGalaxy the movie]].
* The "A Dame To Kill For" storyline of ComicBook/SinCity features [[StrawNihilist Dwight]] [[AntiHero McCarthy]] and [[{{Determinator}} Marv]] as this. Subverted in that [[OneManArmy Marv]] does most of (if not all) the fighting.
** [[BattleCouple Marv & Nancy]] get a moment of this in the second film adaptation. Again though, Marv does the majority of the fighting once they [[spoiler: break into the Roark mansion]], so it's subverted.


[[folder:Fan Fiction]]
* ''FanFic/{{Heroes}}'': Surak compares Kirk and Spock's relationship to the "warrior bond-brothers" he had observed in his own day.
* ''FanFic/InsontisII'': Groping for a Vulcan term to explain his and Spock's relationship, Kirk settles on "pi'kine", which according to the footnotes, means "little shield-partner."
* ''FanFic/TalesOfTheEmperasque'' has all the returned Primarchs, although special mention has to go to Roboute and Corax as seen during the pacification of Terran Hives, where together they pretty much rip Fulgrim's assault to shreds.
* The ''Franchise/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]].
* In ''[[Fanfic/TwiceUponAnAge All This Sh*t is Twice as Weird]]'', Varric tells a story one night at dinner which paints [[VideoGame/DragonAgeII Hawke and Aveline]] as a pair of Smash Sisters. He compares them to the [[VideoGame/DragonAgeInquisition co-Inquisitors]], who are a Bash Brother-and-Sister duo and even identify themselves as being LikeBrotherAndSister.
* Franchise/{{Tron}} - PatchworkFic with the ''VideoGame/TronTwoPointOh'' and ''Film/TronLegacy'' canons will have Sam Flynn and Jet Bradley as this.
* ''VideoGame/KnightsOfTheOldRepublic'' fanfics play with the Mandalorian idea of "vod" (which can mean "brother/sister" or "friend") when it comes to Canderous and the rest of the crew, particularly Revan and/or Carth.

[[folder:Film (Animated)]]
* Manolo and Joaquin from ''WesternAnimation/TheBookOfLife'', since they were kids. Not only do they playfully fight with each other, they also fight together against a common enemy, be it an angry bull as kids or [[spoiler:when they fight Chakal]] as adults.

[[folder:Film (Live Action)]]
* The 2009 ''Film/StarTrek'' film, when Kirk and Spock beam onto the Narada and start shooting up everything in sight.
* In ''Film/BlackHawkDown'' and RealLife, the two Medal of Honor winning snipers, Randy Shughart and Gary Gordon live, breathe, [[spoiler: and die]] this trope. From their hilarious-slash-TearJerker Chess game, which they never manage to finish, to their exchange of looks before they both deploy to aid the downed Night Stalker, the film makes the friendship of the two remarkably clear for two fairly minor characters.
* In ''Film/XMenOriginsWolverine'', Logan and his brother do this for the first fifteen minutes of the movie. The opening sequence is a badass {{Montage}} through UsefulNotes/TheAmericanCivilWar, UsefulNotes/WW1, UsefulNotes/WW2 and UsefulNotes/TheVietnamWar!
** They also come back together briefly at the end, albeit [[EnemyMine for a mutual gain]].
* ''Franchise/StarWars''
** Any cooperative combat in the ''Franchise/StarWars'' prequels, especially between Masters and their Padawans. Obi-Wan and Qui-Gon against Darth Maul in Episode 1 are the best example. It is because of the same thing with Obi-Wan and Anakin in Episode 3 that turned their climactic duel into a sort of FearfulSymmetry.
** The ExpandedUniverse had the [[ProudWarriorRace Mandalorians]] play with the trope. Their term for "friend" is the same term for "sibling." If you've fought enough battles with a Mando'ad, then you're their sibling. No, blood ties or formal adoption is not a requirement. Their culture also sees all who follow the Mandalorian way as brothers and sisters in one big, war-mongering family.
* Probably the best moment of ''Film/SpiderMan3'', with Spider-Man and [[spoiler:New Goblin]] team up during the GrandFinale.
* Fulton Reed and Dean Portman in ''[=D2=]: Film/TheMightyDucks'' were explicitly called "the Bash Brothers." Also affectionately called "Enforcers."
** An enforcer is actually an unofficial role on an ice hockey team, not a title. Their job is to play dirty and violent.
* Aragorn and Gimli did a fine example of this in ''Film/TheLordOfTheRings: The Two Towers''. Needing to give a gate some time to be repaired, Aragorn and Gimli did a flying leap onto the ramp and proceeded to fight off an entire legion of Uruk-hai. One of the best sequences of many impressive ones in the trilogy.
* One of the tag teams in ''Film/NachoLibre'' did a lot of this (also incorporating high-fives and the like), apparently being twin brothers.
* One of the central motifs of HeroicBloodshed movies like ''A Better Tomorrow'', ''The Killer'' and ''Hard Boiled'' is two characters, usually BloodBrothers as well as Bash Brothers, doing this.
* Italian actors Creator/BudSpencer and Terence Hill tend to fight side-by side in the action comedies they co-star in.
* In ''Film/TheChroniclesOfRiddick'', Riddick and Kyra are a rare opposite sex version of this, once they stop fighting each other. The Crematoria sequence showcases it nicely.
* ''Franchise/PiratesOfTheCaribbean'' had this in various sequences, but the most pure form was when Will was trying to free Jack from the noose in the [[Film/PiratesOfTheCaribbeanTheCurseOfTheBlackPearl first film]] and they raced to the castle edge. Subverted in that they taken down plenty of soldiers between the two of them, but sheer numbers and guns outweighed their ability to finish their job.
* ''[[Film/ThreeHundred 300]]'' outlines this in particular when discussing their tactics. The individual Spartan is superior to the individual Persian soldier, but their sheer numbers would overwhelm them in any situation except for the bottleneck position they chose to defend. Even then, only because each Spartan defended the one next to them that they created a near impenetrable line... of course, they don't always follow this rule, often preferring the RuleOfCool and breaking the line for slow-motion individual brawls.
** Astinos and Stelios are this briefly on the second day.
* ''Franchise/MarvelCinematicUniverse'':
** In ''Film/IronMan2'', Tony and Rhodey become this after finally settling their differences.
** Pretty much everyone in ''Film/{{The Avengers|2012}}''. Black Widow and Hawkeye ''constantly'' [[spoiler: once Hawkeye is back on the Avengers' side]], Thor and Captain America, and Thor and the Hulk are particularly notable.
** Rocket and Groot in ''Film/GuardiansOfTheGalaxy'', best exemplified in the prison breakout scene.
** ''Film/CaptainAmericaCivilWar'' has ''two'' pairs: Tony and Rhodey again, and [[spoiler:Steve and Bucky [[Film/CaptainAmericaTheFirstAvenger again]]]].
* The central premise of just about any [[BuddyCopShow Buddy Cop]] movie. [[Film/LethalWeapon Riggs and Murtaugh]], [[Film/RushHour Lee and Carter]], Film/TangoAndCash et al.
* And of course the literal brothers Connor and Murphy [=McManus=] in ''Film/TheBoondockSaints''.
* In ''Film/TheDevilsRejects'', a pair of bounty hunters called the Unholy Two are hired to track down and capture the AxCrazy Firefly clan. They actually succeed and disappear afterwards with no repercussions.
* The films ''Film/TheBarbarians'' and ''Film/DoubleTrouble'' starring the bodybuilder twins Peter and David Paul have their characters constantly bickering with each other and kicking equal amount of ass in fight scenes. This is taken even further in ''Film/TwinSitters'', where their characters call backup from two other duos of twin bash brothers to save two kids from the bad guys.
* As pack animals, the Raptor Squad from ''Film/JurassicWorld'' hunt and fight as a team, best seen when hunting Hoskin's team or [[spoiler: when Delta and Echo battle the ''[[BigBad Indominus rex]]''. Later, [[ActionGirl Blue]] teams up with [[NeverMessWithGranny Mama Rex]] to tag-team the ''Indominus''.]]
* In ''Film/MadMaxFuryRoad'' Max and Furiosa become a formidable team, first as [[EnemyMine reluctant allies]] and then as [[spoiler: literal]] BloodBrothers.
* ''Film/WrathOfTheTitans'' had the brother gods Zeus and Hades against the LegionsOfHell at full power.

* JR Ward's ''Literature/BlackDaggerBrotherhood'' is literally a group of vampires not related by blood who nevertheless live and fight together against the [[BigBad Omega]] and the [[{{Mooks}} Lessening Society]].
* Literature/FafhrdAndTheGrayMouser.
* [[Literature/TheLegendOfDrizzt Drizzt Do'Urden]] and Artemis Entreri can operate like this, much to their mutual displeasure. They're both highly skilled dual-wielders who independently developed extremely similar fighting styles...And it took them about five minutes of conversation for each to recognize the other as what he could have been. Both don't like what they see in the other person, especially when compared to what they see as their strong points. However, if they ''must'' cooperate, they slaughter entire groups of who they're against. Often fighting back-to-back and continually moving, and with one setting up an opening for the other to exploit a second later, and it's mentioned that they move so much in sync that it's tough to tell who's who or who's doing what.
** As can Artemis and Jarlaxle Baenre, although their fighting styles are slightly more different, with Jarlaxle's style also incorporating throwing knives, misdirection, and a HyperspaceArsenal of magic items and wands. Additionally, Entreri is on the other side of their TeethClenchedTeamwork, having gone through some CharacterDevelopment and seeing Jarlaxle as what he used to be, (albeit a more charismatic and witty version) and Jarlaxle, being a bon vivant and trickster to the extreme, sees Entreri as an opportunity to have a roaring good time.
* Caramon and Raistlin in the ''Literature/{{Dragonlance}}'' series.
* Rodrigo Belmonte and Ammar ibn Khairan in Creator/GuyGavrielKay's ''Literature/TheLionsOfAlRassan'' literally fight back to back at one point, taking out some mooks to prove their awesomeness. Later, they're forced to fight one another as the champions of {{Expy}}s of the Muslims and Christians in medieval Spain.
* OlderThanFeudalism: Great Ajax and his half-brother Teucer in ''Literature/TheIliad''. Teucer hunkers down behind Ajax's shield and lays down a RainOfArrows, Ajax finishes anyone who manages to close.
* In ''the Literature/InheritanceCycle'', Eragon and Murtagh shared the field of battle many times early in the series and developed a bond as strong as brotherhood. [[spoiler:It wasn't too surprising when they turned out to actually be brothers.]]
** A more consistent example is Eragon and Arya. It's explicitly stated that they're the other's perfect shield mate.
* ''Literature/SherlockHolmes'': Sherlock Holmes and Dr. Watson]] are a classic case. Just check out the "Awesome" page for the series and note the examples falling under "Holmes & Watson".
* Harry [[Literature/TheDresdenFiles Dresden]] and Karrin Murphy become this, because Harry is a magic nerd who really has no idea at all about women. It's lampshaded as pretty sad several times throughout the series.
** The [[OurWerewolvesAreDifferent Alphas]]: they're a pack of wolves with human-level intelligence. Be. Afraid.
** Harry and Thomas Raith become this. [[spoiler: like the Eragon example, it shouldn't be that much of a surprise that they're half-brothers.]]
** Thomas and Lara Raith in full vamped-out mode cut through an army of super-ghouls like chaff. Harry describes them as matched parts of a force of nature, their stand all the more beautiful and awe-inspiring for being totally hopeless.
%% * The concept of "parabatai" in ''Literature/TheMortalInstruments'' and ''Literature/TheInfernalDevices'' is absolutely this trope. The latter series has the clearest example- Will Herondale and Jem Carstairs- but Jace [[spoiler: Herondale/Lightwood]] and Alec Lightwood of the former also fit.
* Spenser and Hawk from Robert B Parker's stories
* Argus and Ribuld from ''Literature/MordantsNeed'' are so inseparable that they are practically a single entity - and together they are good enough in a fight that they can hold their own, at least for a while, against the most [[SuperSoldier skilled]] and [[TheDreaded feared]] swordsman in the world.

[[folder:Live Action TV]]
* {{Gender Flip}}ped version from ''Series/BuffyTheVampireSlayer'': Buffy and Faith, for a short time in season 3 - most obvious in the episode "Bad Girls". "[[PreMortemOneLiner Rise and shine, boys]]! It's your wake up call!"
** In Season Nine's ''Angel and Faith'', Angel and Faith have this kind of relationship.
* ''Series/GameOfThrones'': Ned Stark and Robert Baratheon were fostered together by Jon Arryn and fought this way in the war against the Targaryens and later fought side by side when they laid siege on the castle of Pyke. When Robert found himself pinned down at Stoney Sept, Ned led the RoaringRampageOfRescue. It's ''very'' SeriousBusiness when Ned declares, "I will ''not'' follow you now," in "The Wolf and the Lion".
* ''Series/{{Life On Mars|2006}}''- Sam Tyler and Gene Hunt have been known to achieve this on occasion.
** On occasion? Tandem desk-leaping & sychronized punching.
* ''Series/TheATeam''. Very much so. [[AFatherToHisMen Hannibal]] knows the strengths and weaknesses of each of the other three team members, and knows exactly how to best use their strengths and minimize their weaknesses. Different as they may be, when they all fight together, it's a bad day for slimeballs everywhere.
** Face and Murdock especially seem to be this. They have a very effective tag-team fighting style.
*** Doubly so for Murdock and B.A. They usually [[VitriolicBestBuds drive each other nuts]], but together they are a force of nature.
* The ''Series/StargateAtlantis'' episode "Midway." A horde of Wraith decide to storm Earth, and slaughter most of Midway station staff. Who's gonna stop 'em? [[OneManArmy Two guys named Teal'c and Ronon Dex]]. The opening featured the two of them trying to beat each other to death but they later turn their combined badassery on the hapless Wraith.
* ''Series/NCISLosAngeles'': G. Callen and Sam Hanna always have each other's back. They bicker sometimes and have a friendly rivalry, but always come through for one another.
* It's always a treat to watch the four team members of ''Series/StargateSG1'' combine to unleash maximum badassness on their enemies.
* Hercules and Iolaus from ''Series/HerculesTheLegendaryJourneys''
** Series/XenaWarriorPrincess and Gabrielle sometimes, though they usually fight separately against the same enemy, not in tandem.
* ''Series/{{Scrubs}}'' featured an ImagineSpot where J.D. visualized [[BlackBestFriend Turk]] and [[AnythingThatMoves The Todd]] going up against kung-fu-fighting surgeons. [[http://www.youtube.com/watch?v=RzzHuTah_u4 The two made a formidable team]]... until the betrayal five.
* Both shown and averted in the ''Series/{{Battlestar Galactica|2003}}'' episode "The Oath": [[spoiler: Bill Adama and Saul Tigh make a last stand at a docking bay. They don't pull off a victory.]]
* ''Series/HawaiiFiveO''. Steve McGarrett and Danny "Danno" Williams argue like an old, married couple - but they always have each other's back in a fight, and God help anyone who comes between them.
* In any Franchise/KamenRider series, expect the main Rider and the secondary Rider to eventually become this. More prominent in the Heisei shows, where it's pretty much the norm for any given show to have at least two riders of its own, but the Showa era had a few of its own like the Double Riders when they were onscreen together, and V3 and Riderman when the latter figured out he should be fighting all of Destron and not just the one guy he had a grudge against.
** A villainous version turned up in ''Series/KamenRiderExAid'' with [[TheVirus Bugster]] duo Graphite and Parado.
* ''Franchise/PowerRangers'' has a few, starting with [[Series/MightyMorphinPowerRangers Jason and Tommy]].
* ''Franchise/SuperSentai'' has its own share as well, such as [[Series/KaizokuSentaiGokaiger Captain Marvelous and Joe Gibken]].
* ''Series/{{Angel}}'':
** Angel and Spike have pulled this off a few times, fighting alternately for good and evil.
** The Groosalugg with Angel, and once with Gunn.
* ''Series/{{Rome}}'': Pullo and Vorenus they start off with an OddFriendship then turn into this, I guess killing over a hundred people side by side and [[BeenThereShapedHistory changing history]] together will do that to you.
* On ''Series/{{Glee}}'', Puck and Finn may hate each other over what happened with Quinn, but they'll team up to defend New Directions.
* ''Series/{{Supernatural}}'''s Sam and Dean Winchester. Raised to fight monsters, we watch them fight monsters. A lot of mutual back-watching.
** Bonus points for being actual brothers. Starring in a show that could be alt-titled 'Brotherhood: (BreakTheCutie with SealedEvilInACan)'.
** Minus points for a very low incidence of acrobatics. It's all grim and 'realistic.'
** Dean and Benny become this [[FireForgedFriends in Purgatory]], as they needed each other to survive, and [[BandOfBrothers after what they went through, became extremely]] close. Dean even says Benny is like a brother to him.
* Michael and KITT from ''Series/KnightRider'' manage to pull this off even though they're a man and a car.
* Used in ''Series/ChinesePaladin'' between Yue'Ru and Xiaoyao.

* Myth/NorseMythology: In the many stories where they weren't [[CainAndAbel beating the crap out of each other]], Thor and Loki often wandered the countryside together, looking for asses to kick. A relationship thought by some to be evocative of Lightning and Fire. Loki also had a great time tag-teaming with his blood-brother, Odin.
* ''Literature/TheEpicOfGilgamesh'': Gilgamesh and Enkidu.
* Myth/ClassicalMythology has the brothers Peleus and Telamon, who were admired as great warriors and frequent allies of Heracles. Their sons would later become Bash Cousins, as Peleus's son Achilles fought alongside Telamon's sons Ajax the Greater and Teucer in the siege of Troy. While Achilles was the legendary badass who slew the Trojan champion Hector in single combat, Ajax was only slightly below Achilles in terms of skill, and nearly fought and killed Hector ''first''.

* To a degree with a well-trained military unit. Most special forces teams are trained this way, covering what their buddies can't. No tossing each other around though as far as I know.
** Fighter aircraft usually fight in pairs, the wingman covering the leader.
*** And also operate in pairs of pairs - a common formation for fighter aircraft (at least in UsefulNotes/WorldWarII) has four aircraft forming a ''flight,'' in which there are two ''elements,'' each with two aircraft constantly covering each other, and each element covering the other. Two well-known formations of this type are the American Finger Four (origin of the name: hold out your hand, fingers together. If each fingernail represents one aircraft, that shape is basically a Finger Four formation) and the German Schwarm (basically identical, just appeared earlier on). The Germans' early adoption of this sort of formation led to some early, easy victories against the Royal Air Force.

* The Steiner Brothers and the Bushwhackers in ''Pinball/WWFRoyalRumble''.

[[folder:Professional Wrestling]]
* Every pro wrestling tag team ever, but some tandems exemplify the big guy/little guy dichotomy particularly well: Wrestling/{{Batista}} and Wrestling/ReyMysterioJr (at least until Batista's FaceHeelTurn), Wrestling/{{Rikishi}} and Scotty 2 Hotty, and Jesse and Festus to name a few.
* Several literal examples:
** The [[Wrestling/ScottSteiner Steiner]] Brothers.
** Harlem Heat (Wrestling/BookerT and Stevie Ray).
** The Wrestling/VonErichFamily in general.
** The Armstrongs.
** The Hart Foundation in most incarnations were related by blood or marriage with the exception of Wrestling/BrianPillman.
** The Villanos
** Wrestling/{{Eddie|Guerrero}} and Wrestling/ChavoGuerreroJr, though uncle and nephew, were only three years apart in age and say they were raised as brothers.
** Wrestling/{{Goldust}} and Wrestling/CodyRhodes.
** The Wild Samoans; in fact most Samoan wrestlers have lineage going back to two or three legendary Samoan wrestling families.
*** Wrestling/TheUsos.
** Carly "Carlito" and Eddie "Primo" Colon.
** Primo and his cousin Tito "Epico" Colon.
** [[Wrestling/MattHardy The]] [[Wrestling/JeffHardy Hardys]].
** Wrestling/TheYoungBucks.
* Several others who weren't really brothers, but were in storyline:
** Wrestling/{{Edge}} and Wrestling/{{Christian}} were billed as brothers for most of their careers. They were HeterosexualLifePartners in RealLife.
** The Beverly Brothers (see Mike Enos and Wayne Bloom below).
** The Minnesota Wrecking Crew of Wrestling/{{Arn|Anderson}} and Ole Anderson were billed as anything from nephew and uncle to cousins to brothers.
** The Brothers of Destruction, Wrestling/TheUndertaker and Wrestling/{{Kane}}.
** [[AmbiguouslyGay Lodi and Lenny Lane]] were mistaken for this.
** Wrestling/TheDudleyBoys, though the misrepresentation was tongue in cheek and deliberate.
* Several other tag teams, while not related at all, real or kayfabe, are inseparable in the minds of fans because they never found or sought individual success. They fought together through thick and thin.
** Wrestling/ScottHall and Wrestling/KevinNash were HeterosexualLifePartners for most of their careers. It should also be noted that both were members of the notorious [[Wrestling/TheKliq Kliq]].
** [[Wrestling/TheRoadWarriors The Legion of Doom]].
** Wrestling/{{Demolition}}.
** Wrestling/TheMidnightExpress.
** Wrestling/TheRockAndRollExpress.
** The Fabulous Freebirds.
** Mike Enos and Wayne Bloom spent much of their careers wrestling as tag team partners in various gimmicks (The Destruction Crew, The Minnesota Wrecking Crew II, The Beverly Brothers, Enos & Bloom).
** Wrestling/{{Sting}} and Wrestling/LexLuger were frequent tag team partners and good friends in RealLife.

[[folder:Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons'': in the typical Fighter-Rogue-Wizard-Cleric party, the Fighter and Rogue fight most efficiently together in a manner similar to this - the fighter directing the battle and drawing the attention of his targets while the rogue tumbles into an advantageous position to deal massive Sneak Attack damage.
* ''TabletopGame/MagicTheGathering'' would frequently set up two cards that are designed to complement each other and other cards controlled by the player in this way. The most pure form is the Brothers Yamazaki from the Kamigawa set, in which the one Legendary per name on the field rule doesn't apply to them and they give each other a major boost when together.
* ''TabletopGame/StarWarsMiniatures'' has some pairs of characters who have Synergy (combat bonuses) or Rapport (cost discounts) when used together. There is also a tournament format called "Dynamic Duo", in which players select only two characters for their squad, who must together cost exactly 100 points.
* ''TabletopGame/{{Warhammer 40000}}'' has a few unit combinations that compliment each others' skills very effectively. Scout Bikers and Terminators in a Space Marine army, for instance; the Scouts have teleport homers that patch up the Terminators' lack of mobility by dropping them on the enemy on a spot that moves very quickly, the Terminators make up for the Scouts' lack of durability and close combat prowess, everyone wins. Except for the poor Tau on the other side of the field that just got a new orifice to defecate through.
* Encouraged by ''TabletopGame/BattleTech'''s Dual Cockpit teams, where a duo of Mechwarriors combine their talents to pilot one 'Mech, very similar to the pilot and weapons/radar officer duo in tandem seat jets. Because bonuses are granted for having both pilots in the same 'Mech fighting together, it usually ends up being the case that both pilots will stick together together outside the 'Mech as well. According to the fluff pilots tend to synchronize before long due to sharing activity outside of the 'Mech and neurohelmet patterns inside it.
* ''TabletopGame/XWingMiniatures'' often designs characters who are close allies in order to work together well. Jan Ors as a HWK-290 pilot can generate bonus dice for others in exchange for gaining stress, while her long-time partner Kyle Katarn's crew card means that you'll get focus tokens when that stress goes away. The reverse arrangement is also synergistic: Kyle as a pilot lets you give away focus tokens, and Jan as a crew upgrade lets you choose to make them evade tokens instead if you'd prefer. Bounty hunting allies Zuckuss and 4-LOM are designed with similar synergy in mind: pilot Zuckuss lets you get attack dice while crew 4-LOM reduces their ability to modify those dice, and if arranged the other way crew Zuckuss lets you generate stress and pilot 4-LOM lets you give it away again. This continues into the ''Film/TheForceAwakens'' era: with the forthcoming "Heroes of the Resistance" box, Rey's pilot ability lets you reroll blanks that Finn's crew card will give you - as long as you have the enemy in your fire arc, anyway.
* This is one way that ''TabletopGame/Exalted'''s Solar-Lunar Bond can manifest. The bond links each Solar Exaltation to a particular Lunar Exaltation and the only certain thing about the bond, should Fate successfully bring the two together, is that it is a strong emotional bond between the two demigod-like Exalted. And a Bash Brothers bromance certainly fits the bill.
* ''Tabletop/WarhammerFantasy'' has several 'dual' legends, consisting of two named and unique characters that canonically fit together. While Vlad and Isabella are more of a BattleCouple, the others mostly fit under this. The most famous are of course Gotrek and Felix, but there's also Kroq-Gar and Grymloq, Karl Franz and Deathclaw, Eltharion and Stormwing, and Louen and Bequis.

[[folder:Video Games]]
* Any co-op game gives players the option for this, from ''Franchise/ResidentEvil'' to ''VideoGame/{{Kirby}}''.
** ''VideoGame/MarioKartDoubleDash'' is built on doing this in a racing game. Each kart has two racers: a driver and a support. They function as one when one person is playing, but if two players decide to go co-op on one kart, racing ability is expanded with one player driving and both players mashing the control stick to achieve miniturbos. The first player can pass items he gets back to the second player, who focuses on using them and can also punch left and right to move the kart a little in those directions to dodge things, attack other players, and steal items.
* ''VideoGame/FireEmblemAwakening'' allows the player to make any two characters into Bash Brothers or Smash Sisters with the Pair Up / Dual system. The more often you do it, or they even stand next to each other, the more often they'll either defend each other from enemy attacks preventing all damage, or double team a enemy offensively. Do it often enough between a male and female duo and they'll [[BattleCouple eventually get married.]]
* The multiplayer campaign options of the ''VideoGame/GearsOfWar'' series features a storyline that kept the main character Marcus with his buddy Dom. A big part of the gameplay involves you yelling at your co-op buddy to cover you while you move forward.
* ''Franchise/{{Halo}}'':
** ''VideoGame/{{Halo 3}}'' has the Arbiter fighting next to Master Chief for much of the game in single player, and all of the game in co-op. You can even include a pair of unique, though undeveloped Elite characters online and play four person co-op. This is in contrast to ''VideoGame/{{Halo 2}}'' where the game has [[GameplayAndStorySegregation no in-universe reason]] why a second Spartan accompanies you on the campaign.
** Also from ''Halo'', the [[GiantMook Hunters]] always come in pairs. In most of the games, they are identically equipped and colored. ''VideoGame/{{Halo 3 ODST}}'' changes this: Hunters can either come in the standard blue armor and [[{{BFG}} fuel rod cannon]] that they had in ''VideoGame/{{Halo 3}}'' or in gold armor and with an explosive fuel rod gun like all Hunters had in ''VideoGame/HaloCombatEvolved''.
* ''VideoGame/DevilMayCry 3'': Dante and Vergil against Arkham. They even say "Jackpot" at the same time.
* ''VideoGame/BioShock2'': As Subject Delta, you are probably the biggest, meanest, and most well armed and armored thing that ever walked through the halls of Rapture. In the last level you get the EleventhHourSuperpower plasmid that is rightfully described as "It's Bring Your Daughter To Work Day". [[spoiler:Together with [[DaddysGirl Eleanor]] even hordes of Brutes, Alphas, and Houdinis don't last against you for more than a few seconds.]]
* [[SuperMarioBros Mario and Luigi]] do this for pretty much every Bros. move in the ''VideoGame/MarioAndLuigi'' [=RPGs=]. And when you start doing the Advanced moves...
** AND in ''VideoGame/SuperMarioRPG'', Bowser and Mario can do this with some of the Koopa King's weapons being various gloves used to throw Mario himself.
** In ''VideoGame/MarioAndLuigiSuperstarSaga'', Popple and Bowser (as "Rookie") do this with new team attacks during their second battle with the Mario Bros. One of the attacks even involves Bowser throwing Popple.
* ''VideoGame/{{Sacrifice}}'' has the Hachimen, even though it's not a fighting game, they're exactly the same thing.
* ''VideoGame/PrinceOfPersiaTheTwoThrones'' in the RingOfFire battle against The Bash Brothers incarnate. To beat them, you have to anticipate that they'll help each other when one is in trouble.
* ''VideoGame/SuperSmashBros'': Popo and Nana, the Ice Climbers.
* Double and especially Triple Techs from the [[VideoGame/ChronoTrigger Chrono]] [[VideoGame/ChronoCross games]].
* ''VideoGame/ArmyOfTwo'' plays this to the letter.
* ''VideoGame/WorldOfWarcraft'' has a few of these as bosses, forcing the players to defeat two enemies working together, effectively turning them into one meta-boss encounter. The Eredar Twins in Sunwell Plateau and more memorably the Twin Emperors of Ahn'Qiraj are boss encounters with two powerful enemies, the battle commonly known as the Bug Trio of Ahn'Qiraj, as the name implies, pits three enemies against the players, the final battle of the Death Knight wing of Naxxramas is against the Four Horsemen-Sir Zeliek, Thane Korthazz, Lady Blameux, and Baron Rivendare (who replaced Highlord Mograine), and from the Crimson Halls of Icecrown Citadel, the Blood Prince Council (super upgraded and revived versions of Blood-Princes Valanar, Taldaram, and Keleseth).
** Cataclysm's Blackwing Descent raid instance has you fighting the reanimated Nefarian after he also brings his sister Onyxia back to life. Just to drive the point home, they attack twice as fast by just being in close proximity to eachother.
** 2v2 [[PlayerVersusPlayer Arena matches]] pit two pairs of BashBrothers against each other.
* One of the attract cinemas for ''VideoGame/{{Tekken}} 5'' shows Kazuya and Heihachi battling an army of Jack cyborgs, until Kazuya throws an exhausted Heihachi their way to secure his escape.
* Billy and Jimmy Lee from ''VideoGame/DoubleDragon'' are famous dor this thanks to the game's co-op availability, which allows two players to play as both of them and kick ass.
* [[Franchise/SonicTheHedgehog Sonic and Tails]] have been doing this since [[VideoGame/SonicTheHedgehog2 Sonic 2]], and Sonic and Knuckles often invoke this when they get over their differences and work together, likewise for Sonic and Shadow on occasion. Meanwhile, Amy and Cream often act as Smash ''Sisters''.
** During ''VideoGame/SonicGenerations'', TimeyWimeyBall allowed for Sonic to do this with himself from the original Genesis games.
** Sonic & Tails are back to their Bash Brother antics in [[VideoGame/SonicTheHedgehog4 Sonic 4: Episode 2]], and aside from the classic Tails-carrying-Sonic tactic, they can create a dual spin dash.
** Team Dark (Shadow the Hedgehog, Rouge the Bat and E-123 Omega) being the [[FireForgedFriends Fire Forged]] TrueCompanions that they are exemplify this probably stronger than Sonic and Tails do.
** SonicHeroes in general is built upon this as it's core mechanic, with all the playable characters being gathered into trios of Bash Brothers (and Sisters) with each character filling a specific role that the others can't. By the time you reach the final levels, you'll be expected to be swapping between roles on the fly with perfect synergy to get a good rank at the end.
* Some sections of ''VideoGame/HalfLife2'' and ''Episode 2'' and nearly ''all'' of ''[=HL2=]: Episode 1'' have Gordon and Alyx working in tandem.
* In ''VideoGame/BanjoKazooie'', the titular pair invoke this trope despite one-half of the duo being female; they perform almost all their moves by working together, and are actually literally inseparable all throughout the first game.
* Any CombinationAttack in a VideoGame/SuperRobotWars game that's not featuring a BattleCouple is usually between Bash Brothers. A standout example is Elzam Von Branstein and Sanger Zonvolt, (proof that ''[[Memes/VideoGames Real Men Ride Each Other]]''...)
* In ''VideoGame/SuperRobotWarsZ'', the game started the thing in which whenever ''Anime/MobileSuitGundamSeedDestiny'' and ''Anime/MobileSuitZetaGundam'' plays a part in any gundam related game, usaully Shinn and Kamille will be this due to Shinn basically being a slightly less stable version of Kamille.
* By the end of ''VideoGame/CallOfDuty: VideoGame/ModernWarfare 2'', [[FieldPromotion Captain]] "Soap" [=MacTavish=] and [[spoiler:Captain Price]] are this. [[spoiler: Yuri takes Soap's place in the later missions of ''VideoGame/ModernWarfare 3'' after Soap dies. Though, to a lesser extent.]]
* In Vile's story mode in ''VideoGame/MegaManX Maverick Hunter X'' the final boss is X and Zero fighting together. Sometimes they'll strategically swap places, but they'll also release attacks together or release them from opposite sides of the screen to trap you. When the boss health bar gets low enough, one of them will fall, but that's [[BattleAura really not a good thing]] ...
* VideoGame/FinalFantasyIX:
** You get four neatly-labelled ones, with the four-way split of your [[TheTeam team of eight]], being Zidane and Quina, Garnet and Eiko ([[spoiler: true sibling summoners]]), Freya and Amarant and Steiner and Vivi. Special mention goes to Steiner and Vivi because of their in-game sword magic command combination.
** Double Bash Brothers moment when Zorn and Thorn decide to mess with Eiko and Mog.
** There's an implied Bash Brothers relationship between Blank and Zidane, but because Blank isn't one of your main characters, it never appears.
** One iconic moment sees Steiner and Beatrix protecting Alexandria together by bashing in the heads of many, many Mistodons.
* Alex and Ryan in ''VideoGame/RiverCityRansom''. In Japan, they're [[DubNameChange known as]] VideoGame/{{Kunio|Kun}} and Riki and they continued to team up in later games (such as in ''Nekketsu Kakuto Densetsu'' and ''Nekketsu! Street Basket'') whenever they were not competing as rivals.
* Sora and Riku in ''VideoGame/KingdomHeartsII''.
** Also most of the main Final Fantasy gang, both during the Coliseum tournaments and the battle of Hollow Bastion. Cloud and [[strike: Squall]]Leon get special mention in a BackToBackBadasses moment.
--->'''Squall Leonhart''': [standing back-to-back with Cloud, surrounded by heartless] Think you can handle this many?
--->'''Cloud''': Well... Might be tough if one more shows up.
--->'''Squall Leonhart''': Hm. Then that'll have to be the one *I* take care of.
--->'''Cloud''': What, you're fighting too?
** DonaldDuck and Goofy. They had been partners years before they even met Sora, and they still have use of their bond, now that creatures of pure evil, led by a bunch of maniacs, are attacking.
* Bill Rizer and Lance Bean from the ''{{VideoGame/Contra}}'' series.
** Can be taken UpToEleven in The Hard Corps, as each character is different and nicely compliments each other if done right.
** ''VideoGame/SunsetRiders'' has this.
* [[strike:[[DubNameChange Paul and Vince]]]], Ralf Jones and Clark Still from ''Ikari Warriors'' and ''VideoGame/TheKingOfFighters''
* ''VideoGame/DynastyWarriors'' has several:
** Gan Ning and Ling Tong evolve from mortal enemies into a grudging version of this. Perhaps most notably at the battle of Shi Ting in [=DW6=], where if you kill one half of the pair the other will become enraged and go into hyper mode. Even before that, they were featured in the [[http://www.youtube.com/watch?v=Yqq0jp6O91g opening]] to ''Xtreme Legends.''
** Guan Xing and Zhang Bao.
** Yue Jin and Li Dian.
** Xu Zhu and Dian Wei.
** Guan Yu and Zhang Fei.
* ''VideoGame/SamuraiWarriors'' also has several:
** Tadakatsu Honda and Ii Naomasa.
** Lady Hayakawa and Kai.
** Todo Takatora and Otani Yushitsugu.
* ''Franchise/AceAttorney'':
** The fight's a bit more metaphorical in ''Ace Attorney'', but Detective Badd refers to his partner Prosecutor Faraday as his "battle-buddy" due to the many legal battles they've fought together.
** Phoenix and Edgeworth fall under this too; they may usually fight against each other in court, but there are several times when Edgeworth helps Phoenix achieve the proper verdict and its obvious how well they work together, with Phoenix jumping to illogical (but correct) conclusions and Edgeworth helping him back up his claims.
** Apollo and Klavier are this, starting the first time they encounter each other in court.
* Donkey and Diddy Kong in ''VideoGame/DonkeyKongCountry1'', Diddy and Dixie Kong in ''VideoGame/DonkeyKongCountry2DiddysKongQuest'', and Dixie and Kiddy Kong in ''VideoGame/DonkeyKongCountry3DixieKongsDoubleTrouble''
* CJ and Sweet in ''VideoGame/GrandTheftAutoSanAndreas'', Tommy Vercetti and Lance Vance in ''VideoGame/GrandTheftAutoViceCity''. [[spoiler:The latter didn't work out so well in the end]].
* ''VideoGame/TeamFortress2'': There's a reason why the Heavy and Medic pairing is one of the most iconic.
** [[FragileSpeedster The Scout]] grew up with Seven older brothers who would roam Boston and get in fights. His speed training was for getting to the fights before they ended.
* ''VideoGame/DragonBallZBudokai 2'' featured this as a mechanic; on the story mode world map, letting two characters with a pre-existing relationship occupy the same space would give one or both of them a stat boost in combat, implying they were looking out for each other.
** The upcoming ''Battle of Z'' will do this by having simultaneous four-player cooperative battles. The game trailer even suggests making teams out of Goku's whole family, or just of a single character's many forms.
* ''VideoGame/DragonBallXenoverse'': This will be the case if your Time Patroller happens to be male. The Time Patroller (regardless of their gender) will team up with certain warriors through out the various quests. The story mode has three particular examples: First, Son Goku who you team up with the most, and during the normal ending, the Time Patroller and Goku defeat the FinalBoss together; second, Trunks who is the Time Patroller's partner; and finally [=SSJ4=] Gogeta who claims to have formed the ultimate tag team with the Time Patroller.
* Schwarz and Jude in ''VideoGame/AgarestSenki2'' to the point they even have a [[CombinationAttack Finish Strike]] together.
* Commander Shepard and Garrus Vakarian in ''Franchise/MassEffect'', acknowledged in-universe in the third game. (It becomes a BattleCouple if they're romanced.)
-->'''Shepard''': There's no Shepard without Vakarian.
* ''VideoGame/Disgaea4APromiseUnforgotten'' actually [[GameplayAndStorySegregation integrates this into gameplay]] with Valvatorez and Fenrich. Apart from starting with a very high likelihood of initiating team attacks with each other, all three of Fenrich's passive abilities are based on Valvatorez's status or positioning (ie. getting a 30% stat boost for standing next to him).
* The Bielert brothers, Oscar and Emile, from ''VideoGame/ValkyriaChronicles'' are [[SiblingTeam somewhat literal]] Bash Brothers.
* [[Manga/{{Heroman}} Joey]] and [[VisualNovel/{{Demonbane}} Kurou]] form a tag team during their duo battles in Arkham City, their friendship is one of the three-cross series friendships in ''VideoGame/SuperRobotWarsUX''
* [[VideoGame/AsurasWrath Asura and Yasha]] rarely see eye-to-eye as part of their RedOniBlueOni dynamic, but by game's end, it's patently obvious that they have had nothing but respect and compassion for each other.
* In ''VideoGame/DynastyWarriorsGundam'', [[Anime/MobileSuitZetaGundam Yazan Gable]] and [[Anime/TurnAGundam Gym Ghingnham]] are portrayed this way, as part of a VillainousFriendship. This actually makes some sense, given that the both of them are massive {{Blood Knight}}s who simply love fighting for its own sake. One random event has the two of them show up as a team in identical Musha Gundams, happily crowing about how awesome these weapons are.
* ''VideoGame/NosferatuTheWrathOfMalachi'': James and Wilfred. "Thanks, brother. I love you. But if you try and hold me to that statement, I'll deny it."
* ''VideoGame/BatmanArkhamKnight'' made this a gameplay element. Build up enough of a hit streak during a fight where an ally is also in the melee, trigger a character switch, and the two characters will perform a ridiculously cool cooperative maneuver to take out one of the opponents before control switches to the second character.
* ''The Cursed Crusade'' features the Templar Knight Denz de Bayle, and the Spainish mercenary Esteban Noviembre, who is either computer controlled or the second player character. There are several moves that require both of them, including having one hold onto an enemy so the other can kill it, or them healing each other.
* Conversed by [=NPCs=] in ''VideoGame/MassEffectAndromeda''. The player character Ryder has an opposite sex twin[[note]]A brother named Scott if a female Ryder, and a sister named Sara if a male Ryder[[/note]] who is also your successor as Pathfinder. Due to events at the beginning of the game [[spoiler:involving a NegativeSpaceWedgie, they are in a coma for the first half of the game and recuperating until they get abducted during the final battle.]] During the post game, Jaal and Liam discuss how awesome it will be when both Ryders take to the field.

* [[SupportingLeader Ciro]] and [[NumberTwo Kareem]] from ''Webcomic/{{Project0}}'', bust into an enemy stronghold and divy up how they complete the mission. apparently they've been doing this for a long time.
* Torg and Riff from ''Webcomic/SluggyFreelance'' do this during the "Dangerous Days" arc, though only after they get done shooting and yelling at ''each other'' first.
* It's hinted that [[Webcomic/MegaTokyo Piro and Largo]] do this in some online games, such as the ''Endgames'' MMORPG.
* Invoked in Webcomic/TheAdventuresOfDrMcNinja, where [[spoiler:to counter Frans Rayner's use of the ConservationOfNinjutsu against the [=McNinja=] clones, Dr. [=McNinja=] switches sides and fights alongside a shocked and confused Rayner, who has no choice but to accept this or else give up and let the clones kill him.]]
* Steve of ''Webcomic/CogaSuro'' is delighted both times he gets to invoke this trope- once in the future with his older self [citing the need for a double-Steve combo move] and again in the sequel with his son.
* The titular heroes of ''Webcomic/NipAndTuck'' are implied to be this, especially [[http://www.rhjunior.com/NT/00258.html here.]]
* ''Webcomic/GirlGenius'':
** Bill and Barry Heterodyne. Alone they were heroic, powerful Sparks. Together they changed the world, and their family's legacy, for the better. And despite their disappearance remain almost universally loved and feared.
** Aldin and Jiminez Hoffman as well.
* ''Webcomic/TowerOfGod'': [[LittleMissBadass Anak]] and [[TheStoic Hatsu]] as well as [[EgomaniacHunter Rak]] and [[MagnificentBastard Koon]].

[[folder:Web Original]]
* The Freelancers [[SiblingTeam North and South Dakota]] are show to be a perfect male/female example of this in ''Machinima/RedVsBlue''.
* [[WebVideo/GameGrumps "Poppy Brothers Juuunior!" "Poppy Brothers SEEENIOR!"]]
* [[Disney/TheHunchbackOfNotreDame Frollo]] and [[Disney/BeautyAndTheBeast Gaston]] from ''WebAnimation/TheFrolloShow'' operate on this principal even when there's not any sort of fight to be had.
* [[WebAnimation/BowsersKingdom Karate Duo Number One!]] [[foldercontrol]]

[[folder: (Number one!) ]]
* In the {{Superhero}} WebSerialNovel ''Literature/GamerGirl2016'', [[CuteBruiser close quarters brawler]] Gamer Girl and [[LongRangeFighter long range support]] Fangirl fight in tandem to compensate for each other's weaknesses on the battlefield.
* In ''Machinima/TheLeetWorld'', Player and Chet.
* The UltimateShowdownOfUltimateDestiny video, ''WebAnimation/{{Haloid}}''. Even more in Haloid's spiritual sequel, ''WebAnimation/DeadFantasy'', most notably with Ayane/Kasumi and Yuna/Rikku, but really all the characters did this constantly.

[[folder:Western Animation]]
* We only get to see it in brief flashbacks, but ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' has Princesses Celestia and Luna taking down Discord and King Sombra. There was also Tirek, but they may have acted more as commanding officers rather than taking action personally in that case for all we know.
** In the Crystal War timeline from "The Cutie Remark, Part 1", Maud and Pinkie Pie are literally {{Smash Sisters}}.
* ''WesternAnimation/JusticeLeague'' would seclude a handful of characters together so they could take on bigger threats. The most common was Franchise/GreenLantern and Franchise/TheFlash, though Franchise/{{Superman}} and Franchise/WonderWoman would occasionally get in.
* ''Franchise/TeenageMutantNinjaTurtles''. In the 2007 TMNT movie, Splinter even said that when they work together and are in the right rhythm, they are unbeatable.
** Raphael from the 2003 cartoon is very dedicated to this trope. While all the Turtles cooperate in battle, he stands out as an especially reliable back-watcher. In nearly every fight, Raph will prevent an enemy from nailing one of his brothers from behind. Lampshaded by Donatello in one occasion:
-->'''Raph''': ''Watch your back, brainiac!''
-->'''Don''': (laughs) ''Isn't that what you're for, Raph?''
** ''WesternAnimation/TurtlesForever'' takes this to the apex with the '03 Turtles eventually fighting in tandem with the '87 Turtles, and the '03 style of straight ninja fighting is contrasted with the '87 slapstick style, with both being equally efficient.
* ''WesternAnimation/TransformersAnimated'' with Prowl and Captain Fanzone when they go to Dinobot Island and have to fight off a slew of mutated creatures. It was that episode that gave some viewers a lot of respect for Fanzone, because even though he didn't like them he was still willing to work with them.
** In-universe, this was probably part of why Fanzone started actually liking the Autobots, or at least tolerating them. In a later episode he even sided with them against [[spoiler: Powell.]]
** Another example is the big guy-little guy team of Bulkhead and Bumblebee. They've been close friends ever since attending Autobot Boot Camp together, and are usually seen watching each others' backs on and off the battlefield. The two have even developed their own variation on the Fastball Special utilizing Bulkhead's wrecking ball hands and Bumblebee's smaller stature.
* ''WesternAnimation/TransformersPrime'' has the villains [[MadDoctor Knock Out]] and [[TheBrute Breakdown]], whose introductory episode had them nearly take down the entire team, including Optimus, by themselves. They are extremely close friends outside of battle too, contrasting the fractured and "out for themselves" Decepticon forces.
** The main reason the Autobots are able to match the Decepticons despite being at a disadvantage both in firepower and numbered forces is because they have bonded closely as a team. Each of them can pair off with the other in combat. The third season episode "Evolution" not only features an epic Bash Brothers with previously at-odds characters Wheeljack and Ultra Magnus, Optimus asserts that their bond as [[TrueCompanions a family]] is what makes them more dangerous than an entire army.
** Optimus and Megatron always become this whenever they are both thrust into an EnemyMine situation against a greater foe.
* From ''WesternAnimation/AvatarTheLastAirbender'':
** The series pretty much makes Aang and Sokka to be this, as well as UnrelatedBrothers.
** "The Blue Spirit" had Aang and [[SecretIdentity Zuko]].
** "The Boiling Rock" had Sokka and [[spoiler:Zuko]].
** [[spoiler: Katara and Zuko]] in "The Southern Raiders". They are seen training [[BackToBackBadasses back to back]] in the finale as well, but don't actually ''fight'' together [[spoiler: as Azula challenges them to one-on-one duels instead]].
* In ''WesternAnimation/TheLegendOfKorra'', Mako and Bolin are actual brothers, and hand out asskicking like a pro team. They've graduated to this status in Books 3 and 4, since they hardly spent time with each other in previous books.
** Korra and Asami are this too, mostly in Book 3 when Mako and Bolin pair off.
** Lin and Suyin, once they settle their differences, are almost always fighting together in major battles, such as double-teaming [[StuffBlowingUp P'Li]] in Season 3 or [[spoiler: helping cripple Kuvira's HumongousMecha]] in Season 4.
*** Wei and Wing, who are also actual brothers, are this every time they accompany their mother Suyin.
* ''WesternAnimation/Ben10Omniverse'' has Ben and Rook Blonko.
* Dr. Girlfriend's Moppets in ''WesternAnimation/TheVentureBrothers'' are dwarfs who fling one another around...
* ''WesternAnimation/SamuraiJack'' featured a fight with Jack and the Spartan King against an octopus-like machine in ''Jack and the Spartans''.
** Likewise Jack and the Scotsman.
* Memorably happened in one episode of ''WesternAnimation/BatmanBeyond'' where Bruce, rejuvenated by a few dips in a Lazarus Pit, fought some mooks alongside Terry, with [[CrowningMusicOfAwesome an electric guitar version]] of the ''WesternAnimation/BatmanTheAnimatedSeries'' Theme blaring in the background.
* In ''WesternAnimation/TeenTitans'': Robin and ''Slade'' during an EnemyMine. Although it works so well because they know each other's styles so intimately and are [[ArcWords similar]]--back in season one, they kept falling into FearfulSymmetry.
** Also, Robin and Red X.
** Cyborg's got the sonic if Robin's got the boom.
** Cyborg and Beast Boy even have their own variant of the FastballSpecial.
** [[BattleCouple Robin and Starfire, occasionally.]]
* A similar example in ''WesternAnimation/XiaolinShowdown'': Omi and Chase Young.
* Luminara and Bariss Ofee in ''WesternAnimation/StarWarsCloneWars''. Their lightsaber fight against the battle droids showed them to be perfectly synchronized.
** Other expanded universe material unveils that the two of them specifically learned to fight like this.
* ''WesternAnimation/StarWarsTheCloneWars'' gives us more of these moments between Obi-Wan and Anakin. They work in perfect tandem whenever they go up against a foe together, Dooku being the most often.
* The WesternAnimation/SWATKats live this trope, though only rarely are they actually fighting in the same room at the same time. When they do, T-Bone acts as TheBigGuy and goes at baddies with fist swinging, while the slighter Razor relies on a quicker, more acrobatic fighting style. The rest of the time, their approach to a problem will still always depend on their teamwork (whether it's air/ground, or piloting/weapons). If one kat is in serious trouble (or worse, unresponsive), the other will get very distressed and might channel that into a "this is for my buddy!" attack.
* Joey and AP from ''WesternAnimation/AtomicPuppet''. As Atomic Puppet, they're a two-in-one superhero who take on anyone that threatens Mega City and make them pay with a one-way trip to the Sun.
* [[WesternAnimation/AdventureTime Finn and Jake]]. They took on a [[NinjaPirateRobotZombie Giant Spellcasting Undead King]] with a [[AmuletOfConcentratedAwesome Magic Gauntlet]], Magic Tiaras and [[ArsonMurderAndJaywalking Sweaters]]. [[spoiler:and won.]]
* [[WesternAnimation/SupermanShazamTheReturnOfBlackAdam Superman and Captain Marvel]]. Their initial efforts to take out the more experienced and ruthless Black Adam separately doesn't work well for the pair. However, once they start working together, they eventually find their rhythm and proceed to lay down a beautiful beat down on him. It was a pleasant contrast to other animated showings of the characters where the two heroes end up fighting each other.
* In ''WesternAnimation/RickAndMorty'', the titular brothers in the ShowWithinAShow ''JustForFun/TwoBrothers'' fight various, increasingly bizarre threats side-by-side.

[[folder:Real Life]]
* In the US, there is an old saying, "A friend will help you move, a good friend will help you move bodies, and a brother will have the bodies moved before it occurs to him to ask why the hell you need bodies moved."
** Another variant: "A friend will visit you in jail, a good friend will bail you out, but a bro will be sitting beside you going 'Damn, that was fun!'".
* Many UsefulNotes/IceHockey forward lines embody a three-brother party. One of many examples would be the "Crash Line" of the New Jersey Devils teams of the 90s and early 2000s. The Crash Line was composed of [[NamesToRunAwayFromReallyFast Bobby Holik, Randy McKay, and Mike Peluso]]; the average weight of a Crash Line player was 215 pounds. Needless to say, the [[MeaningfulName Crash Line]] was a dominating, physical and ultimately instrumental part to the Devils' championship success. They were extremely successful and provided the "grind line" defensive template that is used to this day.\\
The "grind line" terminology was derived from the Detroit Red Wings--who, after being destroyed by the Crash Line in the 1995 Stanley Cup Finals, quickly adopted the same techniques and established [[TropeCodifier the original Grind Line]] of Kris Draper, Joe Kocur, and Kirk Maltby. This line led them to two straight Cups in 1997 and 1998 (and another Cup in 2002 after Darren [=McCarty=] had succeeded Kocur on the line) and permanently encoded this technique in the essence of the game.
* In the late 1980s, Bob Probert and Joey Kocur of the Red Wings were sometimes referred to as "the Bruise Brothers".
* When they both played for the Oakland A's, Mark [=McGwire=] and Jose Canseco were nicknamed "The Bash Brothers" for their one-two punch when put together in the line-up.
* Recently in the NBA, a variant of the term has entered use for describing the Golden State Warriors guard pairing of UsefulNotes/StephenCurry and Klay Thompson - The Splash Brothers, referencing the pair's incredible three-point shooting.
* This in turn led to Oklahoma City Thunder bigs Steven Adams and Enes Kanter being called the "Stache Brothers", from their very notable facial hair.
* Military units in real life, particularly when performing CQB (Close Quarter Battle) maneuvers, such as rescuing hostages.
** Despite the common depiction of a ColdSniper acting alone, dedicated snipers are always deployed with a spotter, someone who can confirm the kill because the actual sniper is too preoccupied with making the shot itself. They are also one to advise on which bullet to use and what modifications to make depending on the situation, as well as double-check the distance to the target.
** In fact, in many situations the spotter is the more experienced soldier, as the spotter's work is more complicated, which is saying something since doing the actual shooting isn't simple point-and-shoot to begin with.
* In social situations there is a strategy involving using the Wingman, a friend that can give even the most skilled of [[TheCasanova Casanovas]] an added edge. Generally, they give a mutual benefit to each other by highlighting each others' strengths, as well as ensuring that neither are completely alone.
* The United States and Australia. The {{Boisterous Bruiser}}s of the English-speaking world, priding themselves primarily on how CrazyAwesome they can be rather than how "civilized" they are. The Australia-US alliance is one of the strongest in the world--possibly stronger than even the US-Canada and US-Britain ones. Since UsefulNotes/WorldWarI, the US and Australia have ''always'' fought beside each other (even if the US was late to the party the first two times, one implies the other). See VitriolicBestBuds for details.
** ...But that still doesn't mean you should shake a stick at the US-UK Special Relationship. [[UsefulNotes/AmericanRevolution After the two]] [[UsefulNotes/WarOf1812 stopped fighting]], they instantly agreed to bury the hatchet and become pals, and now either side can be guaranteed to back the other up. [[UsefulNotes/VietnamWar Some conflicts aside]], the two will always be found together, pulling the other's butt out of the oven once shit hits the fan. There's always some guaranteed HoYay between the two leaders of the respective countries—except during the two periods in which the UK has had [[UsefulNotes/TheMenOfDowningStreet a woman occupying No. 10]]. And the first of the two women of Downing Street was UsefulNotes/MargaretThatcher, widely seen as matching any man for toughness.
** The Anglosphere is built around this, military-wise. Each of the above-mentioned countries can and have engaged in some truly impressive feats during countless battles through numerous wars. The US and Canada had [[MultinationalTeam bi-national special forces units]] during UsefulNotes/WorldWarII, Canada and Great Britain fought together in the trenches to great success during UsefulNotes/WorldWarI. Australia and New Zealand ([[AndZoidberg and Newfoundland]]) fought heroically at Gallipoli (though that ended tragically, they earned the respect and admiration of the Turks). America and Great Britain, as mentioned above, have numerous conflicts in which they did this, as have America and Australia. Australia and Canada also did this at Kapyong during UsefulNotes/TheKoreanWar, proving how CrazyAwesome they could truly be. It helps that the UK, US, Canada, Australia and New Zealand have numerous military (and non-military) treaties and agreements that help to enable this trope. On top of NATO and UsefulNotes/TheCommonwealthOfNations, there is the UKUSA Agreement, AUSCANZUKUS, Five Eyes, ABCA Armies, Combined Communications Electronics Board, just to name a few. All of this adds up to make these nations a terrifying Bash Family.
** Put best by the Michael Joseph Savage, Prime Minister of New Zealand: ''"It is with gratitude in the past, and with confidence in the future, that we range ourselves without fear beside Britain, [[BadassBoast where she goes, we go! Where she stands, we stand!]]"''
** People often forget this, but the alliance older than US-Britain, US-Canada, or US-Australia? The United States and France. The reason being is that France was the United State's ''first'' ally, going all the way back to UsefulNotes/TheAmericanRevolution - even if it was originally a political move to screw over Britain. Of all the alliances both countries have had, this one is one of the longest. In fact, one of the most iconic "American" [[ShapedLikeItself icons]], the Statue of Liberty, was donated to the United States by France. Time and again, both countries have come to the other's aid in their time of need, and the solidarity between the two is very well-known. Much like the US-Australia relations, [[VitriolicBestBuds they may not always get along well]], more so because of the US' predominantly Anglo-Saxon culture, but at the end of the day, they always help each other out.
* The UK and France. While inhabitants of both nations profess to dislike the other intensely, with still popular offensive nicknames 'Frogs' (derived from the French eating frog's legs) and 'Rosbifs' (the latter derived from the famous British love of roast beef and habit of burning in the sun), and sporting contests being a source of intense rivalry, the two nations are much closer than either would like to admit, with five centuries of English Kings having land in France - and de facto French Kings ruling England - from 1066 to the fall of Calais breeding a special connection. French used to be an expected language of anyone who was anyone in England, and is still the most commonly taught foreign language in the UK, while the reverse is true in France - and it is now near required for success in the business world. Millions of inhabitants of both countries go on holiday to the other each year and hundreds of thousands of citizens of both countries reside in the other. And following about 800 years of kicking the crap out of each other, from UsefulNotes/TheCrimeanWar onwards, they've gone from reluctant allies to, following the UsefulNotes/WorldWarI and UsefulNotes/WorldWarII, tighter than brothers - and while they [[VitriolicBestBuds enjoy winding each other up]], they will be the first to support each other in the event of a tragedy.
** To illustrate, France responded to the 7/7 bombings by labelling the attackers 'savages' and instantly offering 'immediate, full and total collaboration of French services in helping you identify the authors of these crimes.' Britain, meanwhile, responded to the 2015 Bataclan gun attacks with similar promises and at a scheduled football friendly between England and France played at Wembley a matter of days later, usually [[TheRival an occasion of intense rivalry,]] the entire stadium was lit up in red, white and blue, the motto of the French Republic was emblazoned on the side, the usual giant St George's Cross at the home end was replaced by a French tricolore, the stadium was filled with banners along the lines of [[YouAreNotAlone 'we stand by you']] [[DueToTheDead and after the impeccably observed minute of silence,]] the English fans all joined in the singing of [[MusicForCourage La Marseillaise - fittingly, a stirring call to arms.]] Barely two weeks later, the previously reluctant British Parliament, which had defeated a previous motion along the same lines two years before, voted to extend air strikes against ISIS to their heartlands in Syria and RAF bombers were in the air within the hour. They may bicker incessantly, but if you go after one of these countries, you'll face the immediate vengeful wrath of the other - and since both are still among the most powerful nations on the planet, this is not a fight you want to pick.
* Sweden and Finland from about the 13th to the early 19th century.
