[[caption-width-right:319:SelfDemonstrating/DoctorDoom and {{SelfDemonstrating/Magneto}} teaming up:\\
[[ThisIsGonnaSuck We're screwed.]]]]

What's worse than one BigBad? Two {{Big Bad}}s, possibly more, working in intentional collusion with each other. Sometimes they will work together just fine; being all respectful and well, but more often than not there will be rivalries between them, and they will tend to break out into a literal example of an EnemyCivilWar.

Not to be confused with TheDragon (a main villain clearly subordinate to the BigBad), though if one of them becomes dominant he may reduce the other(s) to the position of DragonWithAnAgenda, DragonInChief and/or TheStarscream. May overlap with UnholyMatrimony. Contrast BigBadEnsemble, where there are also several Big Bads operating simultaneously, but not necessarily working together or even interacting in any way.

See also VillainTeamUp and BigBadEnsemble. Contrast CoDragons, where one BigBad is directly served by two or more equally ranked lieutenants.

[[folder:Anime & Manga]]
* The God Hand from ''Manga/{{Berserk}}'', [[spoiler:until its revealed that they are led by a being known as [[GodIsEvil The Idea of Evil]]]]
* Yami Bakura and Marik Ishtar in the Battle City arc of ''Anime/YuGiOh'', until [[spoiler: Yami Marik disposes of them both.]]
** [[spoiler:Dark Bakura and Akhenaden]] are this in the final arc of the [[Manga/YuGiOh manga]].
** Placido, Jose, and Luciano in ''[[Anime/YuGiOh5Ds 5D's]]'', [[spoiler: although technically, they are three embodiments of the same person, Aporia.]]
* Kotomine Kirei and Gilgamesh in ''VisualNovel/FateStayNight''. Kotomine makes the plans, Gilgamesh calls people mongrels and swordspams them to death. Or doesn't. He helps if he feels like it, anyway.
* ''Manga/SailorMoon'': Several incarnations of the true BigBad, Chaos, is the true main villain for the StoryArc, while the person we believe is BigBad is TheDragon. However, a few have been to equal BigBad levels, namely Queen Beryl and Queen Metallia of the first story arc.
* V. V. and Charles of ''Anime/CodeGeass'' [[spoiler:until the latter kills the former [[ThatLiarLies for lying to him too many times]]]].
* Towards the end of ''[[Anime/MobileSuitZetaGundam Zeta Gundam]]'', [[MagnificentBastard Paptimus Scirocco]] and [[EvilChancellor Haman Kahn]] join forces. They trash Char doing it, too.
* The Innovades and A-Laws from the second season of ''Anime/MobileSuitGundam00.''
* In ''Manga/{{Naruto}}'', [[BigBad Tobi]] forms an alliance with [[DragonAscendant Kabuto Yakushi]].
** It's debatable whether Tobi and Pain's relationship from earlier in the story was an example of this with Tobi being dominant or simply a straight-up single BigBad and his DragonInChief. Tobi is the [[DiabolicalMastermind master planner]] [[TheManBehindTheMan behind the scenes]] while Pain is the unquestioned leader of Akatsuki with [[PersonOfMassDestruction enough power to flatten most armies]]. Each has their own diabolical plan that actually conflicts with the other, and it's never revealed if either one knew what the other was planning.
** [[spoiler: And now, with Kabuto's defeat, it seems that we have a new Duumvirate with (T)obi(to) and the resurrected Madara. They've been working on the same plan since before Madara's death, so you could say it's the longest running Duumvirate in the series.]]
** [[spoiler: With the recent revelations turns out the longest running Duumvirate in the series was actually the one between the Black Zetsu and Kaguya Ōotsutsuki. How long? Well, just spanning the ''entire'' history of conflict in the Shinobi world!]]
* ''Manga/{{Bleach}}'': The third movie, ''Fade to Black'', has this split between [[ClingyJealousGirl Homura]] and [[TheStoic Shizuku]], two siblings that Rukia adopted before becoming a Shinigami. This pair actually provides a pretty interesting variation: It's clear that these two are the ones responsible for the conflict within the third film, but Shizuku is much more action-oriented, being the one to wield that memory-erasing SinisterScythe. His sister, Homura, acts as support with her MassTeleportation. Furthermore, while Homura is paranoid, obsessive and temperamental, Shizuku is a lot calmer, rational and emotionally stable, but of the two, she's the one calling the shots, while he's loyal and obedient to the letter, even when he disagrees with what she says.
* The Fishman Island Arc of ''Manga/OnePiece'' has [[spoiler:[[MadLove Vander Decken IX]] teaming up with [[ThreateningShark captain Hody Jones]] of the [[FantasticRacism New Fishman Pirates]] to overthrow [[CloudCuckoolander King Neptune]]. Jones wants control of the Island, Decken wants Princess Shirahoshi. Both men's insanity leads both to try and kill each other in the end. It's a subversion though in that the two were no honest threat to the protagonists apart ''or'' together. It's only when things went south in their partnership and Decken went nuts and tried to destroy Fishman Island via a ColonyDrop did they become anything remotely resembling a threat.]]
* ''Manga/{{Eyeshield 21}}'''s last arc has a ''de facto'' Big Bad Duumvirate on the American Pentagram. Elitist [[TheJuggernaut goliath]] Mr. Don is the team captain and the undisputed [[TheLeader leader]] of the team, yet despite his GeniusBruiser status, he spends most of his time serving as the centre, which leaves his ability to lead the team somewhat handicapped. As such EvilGenius Clifford D. Louis makes and executes most of the plans; he's also the only player who isn't frightened of Mr. Don and whom the latter doesn't try to order around, making them an example of this trope.
* In ''Anime/GaoGaiGar FINAL'' Palparepa is officially considered the leader of Eleven Masters of Sol and Pauls Abel is considered to be his [[TheDragon Dragon]], but in reality they have divided the BigBad duties between each other and Abel clearly acts like Palparepa's equal.
* The Table of Contents and Noah in ''Manga/SoulEater'' because the Index was the true mastermind behind Noah.
* In ''Anime/AfterWarGundamX'', the Frost Brothers consider themselves to be one of these, though in practise, Shagia is TheBigBad with Olba acting as TheDragon.
* In ''Anime/ElHazardTheMagnificentWorld'', [[CuteMonsterGirl Queen Diva]] accepts Jinnai as TheChosenOne and leader of the [[BugWar Bugrom Empire's military]], and they are effectively co-rulers from that point on, though Jinnai is by far the more active of the two.
[[/folder]]

[[folder:Comics]]
* Carmine Falcone and Commissioner Loeb in ''ComicBook/BatmanYearOne''.
* Alexander Luthor and Superboy-Prime in ''ComicBook/InfiniteCrisis.'' Superboy-Prime starts out as TheDragon, but gets a power boost mid-story that makes him Alexander's equal.
* Solaris and Vandal Savage in ''ComicBook/DCOneMillion''.
* The three lords of hell in ''ComicBook/TheSandman'' and ''ComicBook/{{Hellblazer}}'': Lucifer Morningstar, Azazel and Beelzebub. Somewhat subverted in that Lucifer is by far the most influential to storylines and Azazel is taken care off in ComicBook/TheSandman. Beelzebub has had little to no importance. [[spoiler:The Kindly Ones]] also swerve back and forth with this, given that they only tenuously qualify as separate beings ''anyway'' and [[spoiler:they only really qualify as antagonists starting with the second to last book; depending [[AlternativeCharacterInterpretation what you think]] of Morpheus' [[DeathSeeker motives]], not even then.]]
* The Leader and MODOK in ''Comicbook/FallOfTheHulks''.
* Hank Henshaw and Mongul in ''Comicbook/TheDeathOfSuperman''. Although by mid story it was fairly clear that Mongul was the underdog of the two.
* The Bulats and Vera from ''Comicbook/ThePunisherMAX'' story arc "The Slavers", the leaders of an [[AcceptableProfessionalTargets eastern European human trafficking ring]]. Cristu Bulat and Vera get along well because they are both [[LackOfEmpathy heartless]] ''business men'', while Tiberiu, Cristu's father, is starting to annoy them and [[PragmaticVillainy damage their business]] with his [[AxCrazy unnecessary cruelty and craziness]]. All of them barely qualify as human beings.
* The ''Comicbook/SinCity'' story ''Hell And Back'' has the corrupt police chief and assassin guild leader working side-by-side along with [[spoiler: TheDon of the series, Herr Walenquist, who is revealed later.]]
* Mr. Sinister and Apocalypse fill this role for a good portion of the ''ComicBook/XMen'' comics, though Sinister is also clearly identified as TheStarscream.
* Megatron and Galvatron in the UK ComicBook/TheTransformers comic story ''Time Wars'' is an example of the big bad teaming up with his past/future self. Predictably a lot of other characters don't survive the story.
* A lot of story arcs in [[ComicBook/LesLegendaires Les Légendaires]] involve two BigBad working together, usually an actual villain and an AntiVillain. Unsurprisingly, it often ends up with the actual BigBad betraying his comrade and the AntiVillain helping the heroes:
** In Book 3 and 4, AntiVillain General Rasga teamed up with [[ArchEnemy Darkhell]]. Darkhell eventually betrayed him, and Rasga sided with the good guys for the end of the battle.
** later, Book 5 and 6 involved Pirate Captain Ceyderom teaming up with [[spoiler:Prince Halan]]. Ceyderom later betrays [[spoiler:Halan]] by siding instead with past Darkhell (or at least trying; it seemed like Darkhell was merely ''tolerating'' his presence), and [[spoiler:Halan]] redeemed himself by committing a HeroicSacrifice;
** The Anathos Cycle starts with Hero turned Anti-Villain Elysio being forced to team up with Darkhell under the Guardian's orders. [[spoiler:Surprisingly enough, this case was the opposite of the usual schema : not only did Darkhell ''not'' betray Elysio, but both eventually redeemed themselves by helping the heroes against BiggerBad Anathos and committing a HeroicSacrifice.]]
* Comicbook/LexLuthor and SelfDemonstrating/TheJoker have done this several times, though the former seriously despises doing so, while the latter often demands to be let in on the plan.
* Original BigBad Hari Vallalkozo and replacements BigBad Douglas Zemeckis from ''ComicBook/{{Orphanimo}}'' briefly form one near the end of the second-last album.
* Dr. Eggman and Dr. Wily in ''ComicBook/SonicTheHedgehogMegaManWorldsCollide''.
* The Crime Syndicate: an [[ThePsychoRangers evil version of the Justice League from another universe]] in ''ComicBook/ForeverEvil''. It's members are [[Franchise/{{Superman}} Ultraman]], [[ComicBook/WonderWoman Superwoman]], [[Franchise/{{Batman}} Owlman]], [[Franchise/GreenLantern Power Ring]], [[ComicBook/{{Firestorm}} Deathstorm]], [[ComicBook/{{Cyborg}} Grid]], [[Franchise/TheFlash Johnny Quick]], and [[ComicBook/TheAtom Atomica]]. They claim to have killed the Justice Leagues and round up super-villains to TakeOverTheWorld.
* Crismus Bonus and Marcus Ginandtonicus in ''ComicBook/{{Asterix}} the Gaul'' seem to work this way, even though Crismus Bonus calls them a triumvirate. However, as shown in their thoughts at one point, when they succeed in [[spoiler:rising against Ceaser]] both of them plan to get rid of the other to, as Crismus said, "become a triumvirate all on his own"
[[/folder]]

[[folder:Fan Works]]
* Princess Jody and Emperor Vakudos in [[http://fanfiction.wikia.com/wiki/Hottie_x_Supetastic_6:_March_Madness Hottie x Supetastic 6: March Madness]]
* FanFic/DungeonKeeperAmi has Alphel and Arachne team up while a third keeper, Nero, serves as a distraction to the bulk of Mercury's forces. Mercury still manages to stomp them in one of the most spectacular [[CrowningMomentOfAwesome crowning moments]] of the series yet!
* Princess Jody and the Dark Overlord from [[http://fav.me/d4a27sp Super Milestone Wars]]
* In Disney fanfic [[http://www.fanfiction.net/s/6048380/1/The_Hellbound_Hearts The Hellbound Hearts]], it's essentially a team-up of numerous {{Big Bad}}s from previous Disney films all either teamed up or fighting against one another. Still, because each one has their own agenda, it's hard to figure out which character will end up being the main antagonist. That being said, this trope is played straight with Xanatos and Maleficent, with both under the belief they're in charge of their particular faction.
* In the ''Manga/DeathNote'' fic ''FanFic/LowLight'', [[KnightTemplar L and Kira]] after L ([[TheCorruption under the influence]] of the [[ArtifactOfDoom Death Note]] and LoveMakesYouEvil) pulls a FaceHeelTurn and joins forces with Kira.
* ''Literature/TheDresdenFiles[=/=]WesternAnimation/MyLittlePonyFriendshipIsMagic'' crossover fic ''Fanfic/MyLittleDenarians'' brings us a Big Bad Duumvirate of Nicodemus and Discord.
** And the ''[[WesternAnimation/MyLittlePonyFriendshipIsMagic Friendship is Magic]][=/=]VideoGame/SonicGenerations'' crossover fic ''[[FanFic/SonicGenerationsFriendshipIsTimeless Sonic Generations: Friendship is Timeless]]'' has Discord teaming up with Sonic's ArchEnemy Dr. Eggman.
* [[VisualNovel/FateStayNight Kotomine Kirei]] and SelfDemonstrating/{{Deadpool}} in ''FanFic/FateZeroSense''. Yes, you read that right.
* Light Yagami and Beyond Birthday in ''FanFic/ThatEpicPlan''--they've portioned it out so they can share power -- Light is in charge of the EvilPlan and [[SlashFic Beyond is in charge in bed]].
* The main plot of ''Fanfic/RetroChill'' is Rupert Chill and Earl teaming up with Retro and Bob to bring down [[ComicStrip/CalvinAndHobbes Calvin.]]
* ''[[Fanfic/MarioAndSonicHeroesUnite Mario and Sonic: Heroes Unite!]]'' brings us a Big Bad Duumvirate of [[Franchise/SuperMarioBros Mario]] and {{Franchise/Sonic|TheHedgehog}}'s [[ArchEnemy Arch-Enemies]] Dr. Eggman and Bowser Koopa.
* ''FanFic/JusticeLeagueOfEquestria'': The second half of ''Mare of Steel'' features a VillainTeamUp of [[Comicbook/LexLuthor Alexander Silversmith]] and Comicbook/{{Brainiac}}. While Brainiac is TheHeavy and the more potent threat, Silversmith's resources prove rather important towards setting up Brainiac's master plan. Technically speaking, [[GeneralRipper Steel Wing]] was in on this too, but he was ultimately just Brainiac's UnwittingPawn and disposed of well before the other two.
* ''FanFic/ShadowsAwakening'' is notable for having ''two'' Duumvirates ([[EvilSorcerer Daolon Wong]] and [[HiddenAgendaVillain The Phantom]], [[EnemyWithin The Queen]] and [[SealedEvilInACan Tarakudo]]) that are [[BigBadEnsemble opposed to]] [[EvilVersusEvil each other]].
* ''FanFic/DaveStdiderPokemonTraner'' has one of the more well-known examples of this in the form of Dave's main enemies, Team Bad, made up of Jack Noir and Karkat Vantas of Homestuck fame.
* ''Legacy of the Fire Empire'', sequel to ''FanFic/TheFallOfTheFireEmpire'', has [[EvilOverlord Li Shang]] and [[HighPriest Aitan]], both of whom has distinct agendas, but are willing to work together to achieve them.
* [[http://www.fimfiction.net/story/89379/vengeance-of-dawn Vengeance of Dawn]] has Breaking Dawn (and her friends) working with Lord Mathios.
[[/folder]]

[[folder:Films]]
* Clarence Boddicker and Dick Jones from ''Film/RoboCop1987''.
* Can be found in the ''Franchise/{{Scream}}'' series. [[spoiler:In fact, the third film is the only one where the killer isn't actually two characters sharing the Ghostface costume. And in the original script, it was]].
* The ''Film/JamesBond'' film series is fond of this trope:
** Kamal Khan and [[RenegadeRussian General Orlov]] in ''Film/{{Octopussy}}''.
** General Georgi Koskov and "[[MilesGloriosus General]]" [[SmallNameBigEgo Brad Whitaker]] in ''Film/TheLivingDaylights''.
** It is [[InternetBackdraft hotly disputed]] whether Renard and [[spoiler:Elektra King]]'s relationship in ''Film/TheWorldIsNotEnough'' is an example of this, Renard being TheDragon or [[spoiler:King]] being Renard's puppet.
* William Stranix and [[spoiler:[[CorruptCorporateExecutive Commander Krill]]]] in ''Film/UnderSiege''.
* [[spoiler:Ward Abbott]] and [[spoiler:[[CorruptCorporateExecutive Yuri Gretkov]]]] in ''[[Film/TheBourneSeries The Bourne Supremacy]]''. [[spoiler:True to form, Gretkov refuses to come to Abbott's assistance near the end of the movie, leading to Abbott's capture by Bourne and [[DrivenToSuicide suicide]] by gun.]]
* Miraz, Glozelle, and Sopespian have elements of this in [[Film/TheChroniclesOfNarnia the film]] of ''Literature/PrinceCaspian''- Miraz is dominant, but he is forced to (grudgingly) rely on the other two. [[spoiler: When they've finally had enough of him, they kill him and become a full Big Bad Duumvirate for the remainder of the film.]] The three have elements of this dynamic in the book as well, though the movie gives all three more screen time and therefore emphasizes it more.
* Cyrus "The Virus" Grissum and Nathan "Diamond Dog" Jones in ''Film/ConAir''. Nathan is ''technically'' taking orders from Cyrus, but they both have equal authority and Nathan admits he is only doing so for the time being.
* [[ColonelBadass Miles Quaritch]] and [[CorruptCorporateExecutive Parker Selfridge]] from ''Film/{{Avatar}}''. "Arguably" because, by the end of the film, EnemyToAllLivingThings Quaritch has rendered the saner Selfridge entirely impotent.
* Eddie Arkadian and Sho'nuff the Shogun of Harlem in ''Film/TheLastDragon''.
* Torrez, Senator Mc Laughlin, and Von Jackson in ''Film/{{Machete}}''.
* The Riddler and Two Face in ''Film/BatmanForever'' with one proving the brawn and the other the brain. It appears to be an unwritten law of comic book movies that a sequel must contain at least two canon villains. [[Film/BatmanReturns Penguin and Catwoman]],[[Film/TheDarkKnight Joker and Two-Face]], [[Film/SpiderMan3 Venom and Sandman]], [[Film/IronMan2 Justin Hammer and Ivan Vanko]], [[Film/TheAmazingSpiderMan2 Green Goblin and Electro]], etc.
* It is unclear if [[SissyVillain Darren]] "[[BloodKnight Wall Street]]" [[HiddenBadass Bettencourt]] was TheDragon to [[CorruptCorporateExecutive Mr. Kwai]] in the first of ''Film/TheTransporter'' movies, or if it was an example of this, with Kwai as the more senior partner.
* Similarly, in ''Film/TheDarkKnightRises'', Bane and [[spoiler: Talia al Ghul]] are either this or [[spoiler: Bane is TheDragon to Talia]]; the movie allows a multitude of interpretations. Although ComicBook/{{Catwoman}} appears, she isn't part of the BigBad club by any means.
* Megatron and [[spoiler:[[FaceHeelTurn Sentinel Prime]]]] in ''Film/TransformersDarkOfTheMoon''. Though by the end of the move, it's clear that [[spoiler: Sentinel]] is the one calling the shots; as Carly points out, Megatron is "[[spoiler: Sentinel]]'s bitch."
* It's heavily implied that the crime syndicate in ''Film/{{Drive}}'' is run jointly by Bernie and Nino, though both aren't always aware of the other's actions.
* In ''Film/HudsonHawk'' the main villains are Darwin and Minerva Mayflower, the world's richest, most evil, most obnoxious couple.
* Boris and his 1969 self in ''Film/MenInBlackIII''.
* Peoples Hernandez and [[Creator/ChristianBale Walter Wade Jr.]] in the 2000 reboot of ''Film/{{Shaft}}''.
* In ''Film/TotalRecall1990'' there's Vilos Cohaagen and [[spoiler:Hauser]], who formulated the plan to take down the Mars Resistance together.
* In ''Film/OzTheGreatAndPowerful'', Evanora, The Wicked Witch of the East, and her AxCrazy sister, [[spoiler: Theodora, The Wicked Witch of the West]] join together to try and take over Oz, and kill Glinda the Good. [[spoiler: They fail.]]
* In the third ''Film/AustinPowers'' movie, Dr. Evil teams up with Goldmember against Austin Powers.
* ''Film/DjangoUnchained'' has Calvin Candie and his head slave Stephen.
* James [=McCullen=] [[spoiler:a.k.a Destro]] and The Doctor [[spoiler:a.k.a Cobra Commander]] in ''Film/GIJoeTheRiseOfCobra''.
* Jeff and the White Ninja in ''Film/MiamiConnection''.
* [[spoiler:Simon Skinner]] and [[spoiler: Inspector Frank Butterman]] in ''Film/HotFuzz''.
* ''Franchise/{{Godzilla}}'':
** ''Film/GodzillaVsGigan'' has both Gigan and King Ghidorah as the {{Kaiju}} villains. Gigan would return to team up with Megalon in ''Film/GodzillaVsMegalon''.
** The two MUTO monsters from ''Film/{{Godzilla 2014}}'' are more or less this, though the female is arguably the bigger threat (and literally the bigger monster) as she carries with her thousands of baby monsters and is the most protective of them.
* ''Film/{{Lockout}}'': Alex and Hydell, the pair of prisoners who lead the riot and are brothers. Between the two, Alex takes center stage as the man with the plan much more often, but Hydell is so utterly psychotic that he's a much bigger threat because of his wanton murder and destruction. [[spoiler:Hydell eventually murders Alex himself to become the main villain for the final minutes.]]
[[/folder]]

[[folder:Literature]]
* ''Literature/AmericanGods'': Mr. World aka [[spoiler:Loki Lie-Smith]] and [[spoiler:Mr. Wednesday. As Wednesday said, [[{{Foreshadowing}} "It's a two man con"]]]].
* ''Literature/ArtemisFowl: The Arctic Incident'': Opal Koboi and Briar Cudgeon. [[spoiler:It is revealed late in the book that Cudgeon plans to kill Opal once gaining power, a fact which proves critical in his downfall via EngineeredPublicConfession.]]
* ''Literature/CounselorsAndKings'': Probably the best way to sum up the…odd relationship main villains [[WoobieDestroyerOfWorlds Kiva]] and [[EvilSorcerer Akhlaur]] have in this ''TabletopGame/ForgottenRealms'' trilogy. They hate each other (or at least, Kiva hates Akhlaur personally - he holds her in contempt, but that's how he treats everyone) but work together to advance their own goals- power (for Akhlaur) and vengeance (for Kiva). As he treats her like a servant, it probably would count more as DragonWithAnAgenda except that Kiva herself in no way sees herself as subordinate and has tons of plans apart from Akhlaur, and in fact tries her hardest to manipulate him (though its made clear he knows what she's doing, and is playing along for his own entertainment). They're best summed up as two distinct {{Big Bad}}s who for the moment happen to be going in the same direction.
* ''Dragon Fate'', the final ''Literature/AgeOfFire'' novel, has [[spoiler: [[ManipulativeBitch Infamnia]] and [[MadDoctor Rayg]]]]. They work together behind the back of [[spoiler: [=NiVom=]]] -- [[DiscOneFinalBoss the apparent villain of the last two books]] -- making him think that they're his loyal servants, while manipulating him into aiding their plans to decimate and enslave the dragon race.
* ''Literature/TheDresdenFiles'':
** For Harry Dresden, it's a good week if he only has two major enemies trying to kill him. Since the Black Council is now confirmed in-universe, technically every single book in the series has at least one obvious villain and the Black Council.
** The necromancers Cowl, Grevane and Corpsetaker in ''Literature/DeadBeat''. Though while they're all technically working together to find the Word of Kemmler, they all intend to betray the others and take the Word's power for themselves. [[spoiler: Of the three, Grevane dies in ''Dead Beat'', Corpsetaker loses her body but survives as a ghost until she's KilledOffForReal in, appropriately enough, ''Literature/{{Ghost Story}}'', and Cowl is still out there as a recurring villain and possibly the series BigBad (and almost certainly aligned with that person or group if he's not).]]
* ''Literature/{{Duumvirate}}'': It's right there in the title!
* ''Literature/HandOfThrawn'': In this Duology, three people are working to create and maintain the illusion that Thrawn has returned, but of the three, Disra and Tierce are the ones at odds. Flim mostly serves as TheWatson, and doesn't seem to have much ambition of his own beyond surviving and being handsomely rewarded. Flim, being a typical con artist, is interested in a short-term reward, claiming that people of his "profession" don't stick around long enough for the mark to take a closer look at them. As such, he knows that he has no prayer in actually running the Empire, especially since he doesn't have the political or the military skills for the job.
* ''Literature/JohnCarterOfMars'': A very tense one shows up in ''The Warlord of Mars'', the third book in this series, consisting of Matai Shang ([[HighPriest Priest King]] of the white Martians, or Therns) and Thurid (a warlord of the black Martians, or First Born). Later in the book it becomes a ''tri''umvirate when Salensus Oll (EvilOverlord of the yellow Martians, or Okar) joins up. Since these three have their own goals and ambitions, there's a fair bit of backstabbing all around. In particular, the white Martians and black Martians ''hate'' each other, they just hate John Carter ''more''.
* ''Literature/LegacyOfTheForce'': While not exactly a BigBad herself, Admiral Cha Niathal works with Jacen Solo [[spoiler:in order to pull a Coup d'Etat on Galactic Alliance Chief of State Cal Omas. This alliance eventually does fall apart with Niathal forming her own faction of the Galactic Alliance opposed to Jacen.]]
* ''Literature/TheLordOfTheRings'':
** SubvertedTrope. Saruman sees himself as Sauron's ally and has full plans of double-crossing him once he gets his hands on the Ring- but Sauron is both far more powerful and more intelligent, knows full well about Saruman's plans, and considers him varyingly a useful tool and a nuisance, but never an equal of any kind, making Saruman a BigBadWannabe.
** Played more or less straight with [[DarkLord Morgoth]] and [[EldritchAbomination Ungoliant]] in ''Literature/TheSilmarillion:'' they team up to destroy the gold and silver trees, humiliating the Valar and setting off the War of the Silmarils, but it ends poorly when Morgoth tries to double-cross Ungoliant. Weakened by pouring his power into making his army and Ungoliant empowered by the light of the Two Trees, only a posse of Balrogs saves him from being devoured.
** However, while Morgoth and Sauron did work together, they do ''not'' fit this trope. When Morgoth was still active, Sauron was his subordinate. Sauron became the BigBad towards the end of ''Literature/TheSilmarillion'' (and throughout ''Literature/TheLordOfTheRings'') as a result of moving into the power vacuum left when Morgoth was imprisoned behind the Walls of Night.
* ''Literature/{{Ravenor}}'': In this ''TabletopGame/{{Warhammer 40000}}'' series, the third book features a union of the two big villains, Zygmut Molotch and Orfeo Culzean. Either could qualify as a MagnificentBastard, and the books hint on the friction that can develop when two [=MBs=] try to work together for extended periods.
* ''Literature/{{Redwall}}'': Happens several different times in this series, although one Big Bad is usually obviously the stronger one and the other doesn't live long. Tsarmina briefly formed one with Bane in ''Mossflower'', Swartt Sixclaw formed one with Zigu in ''Outcast of Redwall'', and for most of ''Martin the Warrior'', Badrang and Clogg formed one.
* ''Literature/TheRiftwarCycle'': Happens between [[EvilSorcerer Belasco]] and [[DemonLordsAndArchdevils Dahun]] in the ''Demonwar Saga'', most recent subseries of this series. Each has his own goals and is manipulating the other to accomplish them. [[spoiler: Both fail and are apparently destroyed, though Dahun comes a hair closer to succeeding]].
* ''The Sacrilege'': This ''{{SPQR}}'' novel gives {{Historical Villain Upgrade}}s to Marcus Licinius Crassus, Gnaeus Pompeius Magnus and Caius Julius Caesar, making them a Big Bad Triumvirate. When the protagonist Decius finds out, he speculates as to [[ItWillNeverCatchOn which of the first two will come out on top of the inevitable power struggle.]]
* ''Literature/ASeriesOfUnfortunateEvents'': The [[TheTropeWithoutATitle man with a beard but no hair and the woman with hair but no beard]]. Even ''Olaf'' is scared of them.
* ''Literature/SpaceVoyages'': Darby and Cornelius Cat, who are also brothers.
* ''Star Wars ABC's'': Gets a LampshadeHanging in this children's book, where most of the major characters get an alphabetic poem written about them. In "Z is for Zuckuss," we read: "Uh-oh, here's that bad quartet/Of bounty hunters Boba Fett/Zuckuss, Bossk and '88...."
* ''Literature/StarWarsCrucible'': Marvid Qreph and Craitheus Qreph, who are brothers.
* ''Literature/TalesOfKolmar'': For most of the trilogy the baddies are Marik of Gundar and Berys. Berys believes Marik's TheDragon, and he ''is'' the more powerful one, but Marik's more important than that and knows it. Ultimately Berys summons the [[spoiler: Demonlord and forces him and Marik into SharingABody]]; the result is under his control but only barely.
* ''Literature/TheThrawnTrilogy'': [[MagnificentBastard Grand Admiral Thrawn]] and the [[WithGreatPowerComesGreatInsanity insane Jedi Master]] [[AxCrazy Joruus C'baoth]] count as this - they have a mutually beneficial alliance, but each has schemes separate from the other and plans to dispose of the other after he's served his purpose. At the trilogy's climax, they are faced simultaneously by two different sets of heroes. While in the process of carrying out their plans to dispose of each other.
* ''Literature/TheVoyageOfTheJerleShannara'': [[DarkMagicalGirl The Ilse Witch]] and her [[EvilMentor former mentor]] [[EvilSorceror The Morgawr]] form one. They have an interesting dynamic, as she's his former [[TheDragon Dragon]], pupil, and BastardUnderstudy, which causes him to treat her as the junior partner, something she deeply resents. When the inevitable breakdown occurs and they do go head to head, the results aren't very pretty.
* ''Literature/TheWarOfTheFlowers'': This series by Tad Williams makes this a DeconstructedTrope - it starts out with a ''tri''umvirate of main villains (fairy lords [[TheChessmaster Hellebore]], [[PresidentEvil Thornapple]] and [[DirtyCoward Foxglove]]), with Hellebore dominant because he's the one with brains, but the other two still clearly his equals, rather than underlings. Then Foxglove gets cold feet and is demoted to hanger-on, while Thornapple is still close to Hellebore's equal and perhaps the closest thing he has to a friend. By the end, Foxglove is a complete nonentity and Thornapple is a clear minion, [[TheDragon if an important one]]- Hellebore is now calling ''all'' the shots.
* The Spangled Mob organization in ''Literature/DiamondsAreForever'' is controlled by two brothers, Jack and Serrafimo Spang, their based being on two different continents.
[[/folder]]

[[folder:Live Action TV]]
* ''Series/TwentyFour'' has done this a few times:
** Andre and Alexis Drazen in Day 1, [[spoiler:though they may have been acting under the orders of their father, Victor Drazen.]]
** The German arms dealer Max, Alexander Trepkos and several other oilmen in Day 2, being the collective [[TheManBehindTheMan men behind]] [[TheDragon Peter Kingsley]].
** [[TheCartel Ramon Salazar and his brother Hector Salazar]] in Day 3. [[spoiler:Ramon ends up killing Hector after Hector keeps interfering with his sale to Michael Amador. Amador himself and his partner-in-crime Marcus Alvers form a second duumvirate.]]
** Debatably, [[spoiler:President Charles Logan and Graem Bauer in Day 5.]]
** Abu Fayed and Dimitri Gredenko in Day 6; later replaced by [[spoiler:Cheng Zhi and Phillip Bauer]]. The former become a triumvirate if General Mohmar Habib is counted.
** Jonas Hodges and General Benjamin Juma in Redemption and Day 7.
** Briefly, [[spoiler:Farhad Hassan]] and Sergei Bazhaev near the beginning of season 8.
** [[spoiler:Charles Logan and Yuri Suvarov later in Season 8 debatably]]
* ''Series/{{Angel}}'':
** [[spoiler:Angelus]] and the Beast in Season 4. [[EvilVsEvil He kills the Beast.]] Except both were subservient (reluctantly, in the case of [[spoiler: Angelus]]) to Jasmine.
** Drusilla with Darla.
* In ''Series/{{Battlestar Galactica|Reimagined}}'', [[spoiler:Tom Zarek and Felix Gaeta briefly team up to attempt to launch a coup against the Roslin-Adama administration.]] [[ShotAtDawn It ends badly.]]
* ''Series/BuffyTheVampireSlayer'':
** Drusilla with Spike at first and then when Angel initially did his FaceHeelTurn, there was more or less an equal partnership going on between him, Spike, and Drusilla. But, with Drusilla becoming more and more enamored with him, and Angel constantly belittling Spike for his crippled status, it soon becomes pretty clear who the alpha dog is.
** Simone was this with Severin in Season 9.
** Ethan Rayne was this with The First Evil in ''[[VideoGame/BuffyTheVampireSlayerChaosBleeds Chaos Bleeds]]''; an odd example, as the Scoobies are technically working with him, as he chose them to be his competitors in a contest he challenged The First Evil to.
* ''Series/BurnNotice'' has Brennan and Larry teaming up in one of the finales.
* ''DarkOracle'': SubvertedTrope where the apparent Big Bad Duumvirate of Blaze and Violet are revealed to be CoDragons to the real BigBad, The Puppet-Master.
* In ''Series/HerculesTheLegendaryJourneys'', several Olympian gods were dedicated to destroying Hercules. They normally worked alone, but at times, they teamed-up. In "Reunions," for example, Hera takes over Olympus with Apollo and Ares siding with her.
* In ''Series/{{Leverage}}'''s fourth season, Victor Dubenich and Jack Latimer form one. Latimer needs Dubenich's brains, while Dubenich needs Latimer's resources. The Leverage crew are able to take them down by targetting the far dumber Latimer, leaving Dubenich, a penniless ex-convict, with no way of getting at them.
* ''Franchise/PowerRangers'' rarely has more than one BigBad, but when it does, this is expected to happen.
** ''Series/MightyMorphinPowerRangers'': Rita Repulsa and Lord Zedd around the time of their marriage, late in the show.
** ''Series/PowerRangersDinoThunder'': In the crossover episode with [[Series/PowerRangersNinjaStorm the previous series]] ("Thunder Storm"), previous Big Bad Lothor teams up with current Big Bad Mesogog to attempt to destroy the rangers.
** ''Series/PowerRangersOperationOverdrive'': In "Follow the Ranger", brothers Flurious and Moltor team up. It doesn't last long due to how much they hate each other.
* ''Series/{{Nikita}}'': The BiggerBad Oversight is composed of a [[OmniscientCouncilOfVagueness committee]], whose members appear to be equal (though Madeleine gets the most screentime, so she's arguably the leader). [[spoiler: It was revealed that [[TheStarscream Amanda]] is in a secret partnership/relationship with Ari Tasarov to jointly plot against their respective superiors.]]
* ''Series/{{Revolution}}'': In the second half of the first season around [[Recap/RevolutionS1E11TheStand episode 11]], de facto BigBad [[GeneralRipper General Monroe]] allied with [[CorruptBureaucrat Randall Flynn]], the apparent leader of the project that caused the Blackout, to secure control of the power-granting Lockets and take over the continent. Randall makes it clear that he's not subservient to Monroe, and Monroe's comments to [[TheDragon Major Neville]] make it clear he's planning on turning on Randall as soon as he's [[YouHaveOutlivedYourUsefulness no longer needed]].
* ''Series/TheShadowLine'' has [[spoiler:Commander Khokar, Commander Penney and Sir Richard Halton]], the leaders of Counterpoint.
* ''Series/StarTrekDeepSpaceNine'': During the Dominion War arc, Gul Dukat and Weyoun serve as commanders of the two halves of the Dominion fleet, and ''despise'' one another. Dukat is later replaced with his [[TheDragon Dragon]], Damar, [[spoiler: who eventually leads Cardassia to break away from the Dominion]].
** Gul Dukat (and later, Damar) and Weyoun serve as [[CoDragons Co-Dragons]] of the Changelings, represented by the Female Shapeshifter.
* ''Series/TheVampireDiaries'': In season one, Richard Lockwood and Jonathan Gilbert. Lockwood is ultimately the leader, Gilbert comes close to the DragonInChief.

[[folder:Pinball]]
* [[Series/DoctorWho The Master and Davros]] (and his Daleks) team up in ''Pinball/DoctorWho''.
[[/folder]]

[[folder:Video Games]]
* SelfDemonstrating/{{Bowser}} and [[Franchise/TheLegendOfZelda Ganondorf]] have this sort of relationship in ''[[VideoGame/SuperSmashBros The Subspace Emissary]]''. As one may expect, Ganondorf gets a little tired of Bowser's company. It becomes a triumvirate if Wario is included, though he rarely bothers to involve himself with his fellow "teammates".
* Joker and Lex Luthor in ''[[VideoGame/LegoAdaptationGame Lego Batman 2: DC Super Heroes]]''
* ''VideoGame/GrandTheftAuto''.
** Frank Tenpenny and [[spoiler:Big Smoke]] in ''VideoGame/GrandTheftAutoSanAndreas''.
** Jerry Martinez and The Mendez Brothers in ''GrandTheftAutoViceCityStories''.
** Dimitri Rascalov and Jimmy Pegorino *
* Bob Page and Walton Simons in ''VideoGame/DeusEx''.
* A BigBad ''tri''umvirate is found in ''VideoGame/{{Oddworld}}: Abe's Exoddus''. General Dripik of the Slig Barracks, Vice President Aslik of [=FeeCo=] Depot and Director Phleg of Necrum Mines and Bonewerkz, respectively. An inversion of TheManBehindTheMan occurs, as the previous game's BigBad, Molluck, is revealed to have been their superior.
* Gol and Maia Acheron of ''Franchise/JakAndDaxter''.
* Shang Tsung and Quan Chi in ''VideoGame/MortalKombatDeadlyAlliance''.
* [[PresidentEvil Kombayn Nikoladze]] and [[spoiler: [[RenegadeRussian rogue]]]] Chinese General Kong Feirong of the first ''VideoGame/SplinterCell'' game. Like the ''Bourne Supremacy'' example, [[spoiler: Nikoladze abandons Feirong, causing him to [[DrivenToSuicide attempt suicide]] by gun, though he is stopped by Fisher before doing so.]]
* ''VideoGame/WildArms1'' has one of the most horrific inducing examples in the second half. [[spoiler:It's Mother and Ziekfried merged as one entity. The horror is that the merging happened because Mother ''ate'' Ziekfried.]]
* The eponymous characters in ''VideoGame/KnightsOfTheOldRepublicIITheSithLords'' are often called the Sith Triumvirate, although only Darth Sion and Nihulus ever work together as equals; the first third member was the BigBad and Sion and Nihilus were her CoDragons and the replacement third member was never an official member of their organization. Cut content shows that Sion and Nihilus' relationship is actually a subversion, as during a [[http://www.youtube.com/watch?v=2_4r6GjgWDI deleted scene]] from the game that was eventually restored by modders, Darth Sion confronts Darth Nihilus aboard the latter's ship to boast about his success in "killing" the player character. Nihilus responds by forcing Sion to the ground effortlessly, and then letting him walk away humiliated; Nihilus didn't care about Sion, to the point where he considered the Lord of Pain so weak that he wasn't worth killing.
* Every ''Franchise/FireEmblem'' game in the [[VideoGame/FireEmblemAkaneia Archanea canon]] features [[OurDragonsAreDifferent Medeus]] and [[EvilSorceror Gharnef]] in such a duumvirate - Gharnef specifically revives Medeus from his centuries-long death for this purpose, but it's implied he has plans which transcend Medeus and will (try to) dispose of him once he's done; for his part, since [[OrcusOnHisThrone he cannot leave his castle]] without losing his power or risking death, Medeus relies on Gharnef to actually execute their plans for dominating Archanea.
* [[spoiler:Captains Romulus Slag and Angstrom Darkwater]] in ''Franchise/RatchetAndClank Future: Quest for Booty''.
* [[spoiler: Krelian and Miang]] in ''VideoGame/{{Xenogears}}''.
* ''VideoGame/FinalFantasyXI'' had the Ace Cardians in the Windurst mission line.
* ''VideoGame/FinalFantasyXII'' had [[spoiler: Venat and Vayne, who together wish to free Ivalice from Occuria's control. Venat is more like a WellIntentionedExtremist while Vayne more appropriately fits the BigBad role but they do work together. Venat and Dr. Cid might also qualify.]]
* ''VideoGame/FinalFantasyXIII'' has [[spoiler: Barthandelus and Orphan, who collaborate to bring about the destruction of Cocoon; however, the former of the two is given much more focus in the game itself, while the latter serves as the game's final boss.]] Actually a unique example because [[spoiler: Barthandelus and Orphan essentially [[FusionDance fuse]] for the final boss.]]
* In ''VideoGame/{{Psychonauts}},'' [[DepravedDentist Dr. Loboto]] and [[spoiler:Coach Oleander]] work together to conquer the world. The latter eventually [[spoiler:undergoes a HeelFaceTurn,]] though, after Loboto [[DisneyVillainDeath falls out of the asylum]].
* Diablo, Mephisto, and Baal, the [[DemonLordsAndArchdevils Three Prime Evils]] in the ''{{VideoGame/Diablo}}'' games. Diablo is the BigBad in the first game and at least the FinalBoss in the second, and Baal is the BigBad in the expansion, while Mephisto is an intermediate boss in ''VideoGame/DiabloII'', but for the plot as a whole they are equals. They seem to be loyal to each other too (well, they are brothers). [[VideoGame/DiabloIII The third installment]] makes it explicitly clear that the Prime Evils are willing to work together so long as it suits their individual agendas, but that Hell has never really posed a serious threat to Heaven before because the Prime Evils have never been able to resist the temptation to stab each other in the back a bit too soon.
* ''VideoGame/{{Warcraft}}'': In the first game, Gul'dan and Medivh are this, both being responsible for the orc invasion. Also, ever since Sargeras [[OnlyMostlyDead only mostly kicked the bucket,]] his CoDragons Archimonde and Kil'Jaeden have been carrying on his crusade against life together. Until Archimonde bites it, that is, leaving Kil'Jaeden sole acting BigBad.
* ''VideoGame/BlazBlue'' features [[spoiler:Relius Clover and Terumi Yuuki]], who have been orchestrating every bad thing that's happened in the series' storyline from behind the scenes, for well over a hundred years, all in their mission to, essentially, kill God. Making matters worse is that both of them are [[EvilGenius insanely brilliant]], one being an [[MoralEventHorizon amoral]] MadScientist (though a very calm and cultured one), the other being a [[AxCrazy psychopathic]] [[CrazyPrepared tactician]] who [[{{Troll}} delights in taunting people and ruining lives]]. Oddly enough, the two get along rather well with each other, and act as RedOniBlueOni to one another. Then subverted in Chronophantasma where it's revealed that [[spoiler:They were [[UnwittingPawn Pawns]] to the real BigBad Izanami,The Goddess of Death as well as possessing Saya and later abandons them to their fates.]]
* ''VideoGame/EarthBound'': Considering [[MindScrew what game we're talking about]] [[EpilepticTrees it's very open to interpretation]], but [[EldritchAbomination Giygas]] and [[FatBastard Porky Minch]] as this is a common interpretation; Giygas himself is [[WithGreatPowerComesGreatInsanity incapable of coherent thought by this point]] so Porky pulls his strings, but at the same time Porky is not even close to being powerful ([[DirtyCoward or bothered]]) enough to do this stuff himself. [[spoiler:As of ''VideoGame/{{MOTHER 3}}'', Porky does graduate to being a full-fledged solo BigBad, but by then he'd had plenty of time to rise to power alone.]]
* The teamup of SelfDemonstrating/DoctorDoom and [[Franchise/ResidentEvil Albert Wesker]] in ''VideoGame/MarvelVsCapcom3''. There's also a SealedEvilInACan that they accidentally released to count, [[spoiler:that being Comicbook/{{Galactus}}. But if Wesker's ending is to believed, ''that's part of the plan'']].
* ''VideoGame/DCUniverseOnline'' has Lex Luthor, The Joker, and Circe as the trio who are in control of the villain side.
* In the ''[[VideoGame/TheLegendOfZeldaOracleGames Legend Of Zelda Oracle games]]'', [[spoiler:Koume and Kotake are the {{Big Bad}}s, whose motive is to revive their surrogate son Ganon.]]
* ''VideoGame/FallFromHeaven'' reverses the usual fantasy conventions: The good gods are individually powerful but tend not to get along well, while the evil ones are all trying to twist Creation together just to make a point to the original Creator. They even run their afterlives (hells) together as a well-oiled machine to create twisted daemons, unlike the good gods whose afterlives are all disconnected.
* Sarah Kerrigan and Arcturus Mengsk become this briefly in ''VideoGame/{{StarCraft|I}}: Brood War'', until Kerrigan decides otherwise. In somewhat of a subversion, they are working with the good guys against a faction of space Nazis. By the time they return to being villains, they're at each other's throats again.
* [[spoiler:Dr. Harlan Fontaine and Leland Monroe]] in ''VideoGame/LANoire''. [[spoiler: While Monroe runs the Suburban Redevelopment Fund's syndicite, who is the one with the ambition of making money off the city, Fontaine the mastermind behind the plans as he is the one who masterminded Courtney Sheldon's drug deals which put him in conflict with Mickey Cohen, as well as Ira Hogeboom's arson crimes.]]
* TK and [[spoiler: Sullivan]] in ''VideoGame/DeadRising2''.
* ''Franchise/SonicTheHedgehog'':
** Eggman does this with his alternate dimension counterpart Eggman Nega in the ''VideoGame/SonicRushSeries''.
** In ''VideoGame/SonicGenerations'', [[spoiler: Dr. Eggman does this with ''himself.'']]
* In ''VisualNovel/SayaNoUta'', this overlaps with [[spoiler:VillainProtagonist, if Fuminori decides to stay with Saya.]]
* [[spoiler: The Eerie Voice and Malevolent Entity]] in ''Persona4Arena.'' [[spoiler: But the Malevolent Entity wants to get rid of the Eerie Voice, which, if the theories about him being Nyarlathotep are true, would be fitting of his Complete Monster status.]]
* ''VideoGame/BattleRealms'' Zymeth and the Nightvol.
* ''VideoGame/HyperdimensionNeptuniaMk2'' has the [[FunWithAcronyms Criminal of the Free World]] who want to get rid of the CPU goddesses and [[DigitalPiracyIsEvil spread out piracy]], while it's sequel, ''VideoGame/HyperdimensionNeptuniaV'', has the Seven Sages, people who want to get rid of the CPU goddesses [[WellIntentionedExtremist because they think that Gamindustri can move on its own without any CPUs to guide them.]] Of course, they're not exactly united in that regard.
* ''VideoGame/MarioAndLuigiDreamTeam'' has Bowser and Antasma, who team up to take over the island and world, as well as use the power of the Dream Stone for their own evil ends. [[spoiler:Guess who betrays who in the end? It's not actually who you think it is.]]
* ''VideoGame/TalesOfXillia'' gives us Gaius and Musét.
* In ''VideoGame/JediOutcast'', the two {{Big Bad}}s are a fallen Jedi named Dessan and an Imperial officer named Galak Fyyar. Both appear to be working together, but privately have different goals. In particular, Dessan wants to use the power of the Valley of the Jedi to create an army of force-sensitives with which to topple the New Republic and create an empire of his own. Fyyar has been heavily mining a rare mineral called cortosis capable of resisting lightsabers in order to be able to effectively counter Jedi and, when the time came, Dessan and his Reborn soldiers, in order to restore the Empire and rule it.
* In ''[[VideoGame/MetroidPrime Metroid Prime 3: Corruption]]'', the Space Pirate leader [[ArchEnemy Ridley]] apparently joined forces with Dark Samus so that they can take down their common foe, Samus, together. [[OmnicidalManiac However, Dark Samus herself already has her own plans at work]].
[[/folder]]

[[folder:Webcomics]]
* Magus and Sirleck from ''Webcomic/ElGoonishShive''.
* The Three Fiends, aka the Directors, from ''Webcomic/TheOrderOfTheStick'' form a triumvirate. The three seem to be equal in every respect, which makes sense, since their goal is to bring an end to the fighting between their three races. They also might turn out to be the Big Bads, though they haven't got much screen time yet.
** Xykon and Redcloak originally were a duumvirate (or triumvirate if you count Right-Eye), but this eventually changed when it became clear as Xykon became more powerful and more completely depraved. Redcloak was eventually demoted to TheDragon (and possible [[TheStarscream Starscream]]). [[spoiler:[[ManipulativeBastard Or at least, that's what Redcloak is happy to let Xykon and the rest of the world believe]].]]
* Brian and Angelo from ''Webcomic/OurLittleAdventure''. In addition to that, they are also a [[UnholyMatrimony married]] [[YaoiGuys couple.]]
* Ian and Anita in ''Webcomic/ErrantStory''. Both are [[ManipulativeBastard Manipulative Bastards]], and neither has any illusions about the other one's goals and objectives, but they find it convenient to work together. At least, until they don't, but by then it's too late.
[[/folder]]

[[folder:Web Original]]
* Literature/WhateleyUniverse example: [[EldritchAbomination The Bastard]] and The Necromancer.
* ''Machinima/RedVsBlue'''s eight season, ''Revelation'' has [[spoiler:Agent Washington and the Meta]], with The Chairman as a HeroAntagonist BiggerBad.
* ''Theatre/{{Starship}}'' has [[AffablyEvil Pincer]] and [[spoiler:Junior]].
* The {{Metaverse}} is menaced by ''WebVideo/CoyleCommand'', led by Coyle Commander, the WebVideo/NewVillainOrder, led by Demon, and The Roaming Eye of Doom, led by Octavius Fong.
* During the Strex Takeover arc of ''Podcast/WelcomeToNightVale'', we have [[StepfordSmiler Kevin]] and [[FauxAffablyEvil Lauren Mallard]]. It's difficult to tell which one's in charge and which one isn't so it's probably safe to assume that they're both leading members of Strexcorp.
[[/folder]]

[[folder:Western Animation]]
* The Quintessions from ''Franchise/{{Transformers}}'', being many villains that work together and being that each has multiple personalities. During G1's third season, the Autobots had to contend with the Decepticons and the Quintessions (who sometimes worked together to achieve their own mutually exclusive ends).
* Moog Magister and Hector Sinestro in ''ComicBook/MonsterAllergy''.
* [[MagnificentBastard Xanatos]] and [[KillAllHumans Demona]] for the first season of ''WesternAnimation/{{Gargoyles}}'' and about 1/3 of the second season. At that point their goals and methods become too divergent, and Xanatos [[EnemyMine teams up with the heroes]] to stop Demona from turning the population of New York to stone.
* ''Franchise/TeenageMutantNinjaTurtles''
** ''[[WesternAnimation/TeenageMutantNinjaTurtles2003 Teenage Mutant Ninja Turtles: Fast Forward]]'', the two main villains were invading alien Sh'Okanabo and [[CorruptCorporateExecutive corrupt C.E.O.]] Darius Dun. Despite different goals and storylines, they established a resource-sharing relationship, where Darius gave Sh'Okanabo the stolen plans for nephew Cody Jones' time window, in exchange for the assistance of the turtle clones Sh'Okanabo had created.
** In [[WesternAnimation/TeenageMutantNinjaTurtles1987 the 1987 cartoon]], the conventional opinion seems to be that Shredder is TheDragon and Krang is the BigBad, but that could easily be just because TheDragon is a much better-known trope than Big Bad Duumvirate. There is no question that Shredder sees himself as a BigBad in an equal partnership with Krang, and it usually seems as if most of the characters agree (Krang may be the only one who sees himself as Shredder's boss). And in an alternate history where the villains succeed in [[TakeOverTheWorld taking over the world]], who is the natural choice for the position of Emperor? Hint: The episode isn't titled "Krangville."
* In seasons four through six of ''WesternAnimation/TheFairlyOddParents'', Anti-Cosmo, the leader of the anti-fairies, and HP, the leader of the pixies, seemed to have equal claim to the title of BigBad. This is especially notable in season six, where the two never appeared without the other.
* In season 2 of ''WesternAnimation/{{Metalocalypse}}'', Metal Masked Assassin and Edgar Jomfru act as the season's Big Bads when they form the Revengencers, appearing in several episodes of the season. Could possibly be considered a triumvirate after they establish an alliance with Lavona Succoboso in the season finale. In a less blatant example, General Crozier and Cardinal Ravenwood could be considered the first season's Big Bad Duumvirate (with Metal Masked Assassin as their [[TheDragon Dragon]]).
* The Almighty Tallests of ''WesternAnimation/InvaderZim'' that the VillainProtagonist serves. Normally it'd just be a singular EvilOverlord, but since [[AllThereInTheScript Red and Purple]] are the same height they're the joint rulers of TheEmpire (though Red seems to be a bit more competent).
* In Disney's ''Disney/{{Dinosaur}}'', the villains are a pair of Carnotaurus threatening to destroy the Herd and prevent them from returning to the Nesting Grounds.
* Mojo Jojo, Princess, Fuzzy Lumpkins, and Him teaming up in ''WesternAnimation/ThePowerpuffGirls'' parody of the Beatles "Meet the Beat-Alls".
* Professor Pericles and Mr. E in the second season of ''WesternAnimation/ScoobyDooMysteryIncorporated''.
* ''Franchise/{{Ben 10}}'' did it several times in all three series:
** {{Big Bad}}s [[ArchEnemy Vilgax]] and [[EvilCounterpart Kevin 11]], respectively from season 1 and 2 of [[WesternAnimation/{{Ben 10}} the original series]], teamed up at the end of season 2 in an attempt to take the Omnitrix from Ben. Kevin's betrayal eventually caused the alliance to fail and led to both of them being trapped in the Null Void.
*** Later, the Forever King, BigBad of season 4, assemble a team made of several of Ben's old enemies for the season finale while most of them weren't that much of Big Bads (guys like Clancy or Rojo had only appeared once before), the team still included Charmcaster (Gwen's {{Arch|Enemy}}[[TheRival rival]]) and Dr Animo (Ben's third most dangerous enemy back then).
** Vilgax teamed up with Albedo in the ''[[WesternAnimation/Ben10AlienForce Alien Force]]'' finale in a new attempt to take the Omnitrix. Though the alliance was successful, Vilgax then betrayed Albedo, and Ben was able to defeat him alone.
* The BigBad of the second season of ''WesternAnimation/{{Wakfu}}'' is initially set up to be Rushu, the [[OurDemonsAreDifferent king of Shushu]] until [[spoiler: Qilby]] becomes another Big Bad of the season and the two team up.
* Lex Luthor and [[spoiler:Braniac]] during the Cadmus Arc of ''[[WesternAnimation/JusticeLeague Justice League Unlimited]]''.
* In Book 2 of ''WesternAnimation/TheLegendOfKorra'', it is possible that [[spoiler:Vaatu]] and Unalaq were this rather than [[spoiler:Unalaq being TheDragon to Vaatu. While Vaatu was far more powerful than Unalaq, he was largely helpless for most of the season until Unalaq's machinations allowed him to escape, and Unalaq did so out of his own ambition rather than any loyalty to Vaatu. This comes across most strongly in the finale, where they merge into the Dark Avatar and are treated as a single threat, rather than Vaatu overriding Unalaq ([[HijackingCthulhu or the other way around]]) like [[EvilIsNotAToy most similar situations]]]]. Book 2 of ''WesternAnimation/AvatarTheLastAirbender'' also ended this way, with [[TheDragon Princess Azula]] and [[EvilChancellor Long Feng]] teaming up to perform a coup on the Earth City capital, Ba Sing Se. However, from the beginning both were planning to betray the other with Azula planning to take it for the Fire Nation and Long Feng planning to take control from the Earth King and have a more iron-fisted ruler for the Earth Kingdom. When the coup is complete, [[MagnificentBastard Azula]] turns his own men against him, having impressed and terrified them with her ruthlessness and cunning, ending it with a BreakingSpeech.
* [[AlphaBitch Whittany and Brittany Biskit]] from ''WesternAnimation/LittlestPetShop2012''.
