* In ''Series/ResurrectionErtugrul'', Karatoygar (Politician who leads the Seljuks) and Petruchio (Master of the Amanus Mountains Templars) have an alliance of some sort in the first handful of episodes of season 1 due to the Seljuks backing the Templars legally and threatening Ertugrul after Ertugrul rescues Halime and her family from a small group of Petruchio's knights. Later, Al Aziz (In charge of the Arabs in Aleppo) and Titus (The latter being TheDragon to Petruchio) are also shown to interact with each other and conspire against Ertugrul despite their differing affiliations.
** Season 2 does this with Noyan and [[spoiler: Sadettin Kopek once the latter arrives,]] working with one another to impede Ertugrul but neither man being truly subordinate to the other since they are associated with distinct entities.
** Season 5 has quite an elaborate one: it starts with Emir Bahaddin and The Mongols (The former being backed up by the latter during his tenure in Konya), and later [[spoiler: Albasti, who fills in the void after Bahaddin is dispatched]]. [[spoiler: ''Then'', Dragos becomes part of the villain network after Albasti makes an agreement with him to eliminate the Kayis]].
* ''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.

* ''Series/{{Supernatural}}'':

** Season 10: Crowley and his mother, Rowena, are set up as being this throughout Season 10, but their alliance falls flat midway into the Season. [[spoiler: The final episodes make it clear that the BigBad of the season are [[HeWhoFightsMonsters Sam and Dean Winchester]].]]
* ''Franchise/SuperSentai'':
** ''Series/HyakujuuSentaiGaoranger'': The Three Highness Duke Orgs all work as the leaders of the Org race as a whole, with Org Master being but a mere figurehead they made to serve as an idol to rule over the lesser Orgs.

Both use into one of the series' final threats, Don Quervo.]]
* ''Series/TrueBlood'': A few seasons had these
** Season 4: Marnie and Antonia, up until around episode 10 when Antonia has a HeelFaceTurn and Marnie becomes the BigBad all by herself.
** Season 5: Salome and Bill. Although, by the finale, they both take the backseat to Lilith, who is the one manipulating them and controlling it all.

The former wants to free his kind from their [[SealedEvilInACan imprisonment]] inside the Ghost River Triangle, while the latter wants to find the remains of her demonic sons so that she can resurrect them, and they're willing to aid each other in achieving their own goals for the sake of reaching their own. [[spoiler:When they turn on each other near the end of the season, Bobo [[EvilerThanThou comes out on top]], leaving him the sole BigBad.]]
** Season 2 has the Widows, a pair of demonic sister-wives, working in concert to resurrect and [[SealedEvilInACan free]] their husband Bulshar, the GreaterScopeVillain of the series. [[spoiler:At the end of the season, they're also joined by a [[BackFromTheDead resurrected]] Bobo.]]

* ''Series/BuffyTheVampireSlayer'':
** At the start of Season 2 Drusilla and Spike filled this role, then when Angelus 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 Angelus 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 for him, as Ethan chose them to be his competitors in a contest he challenged The First Evil to. Ethan will become a Chaos Demon if he wins the contest.
* ''Series/BurnNotice'' has Brennan and Larry teaming up in one of the finales.
* ''Series/ChillingAdventuresOfSabrina'': [[DemonLordsAndArchDevils Mary Wardwell/Madame Satan]] and [[HighPriest Father Blackwood]], who are both working for {{Satan}} and trying to secure Sabrina's soul for him, even if they don't like each other and have very different methods and ideas of how to do so.

** Season Four has Clifford and Marlize [=DeVoe=], also known as the Thinker and Mechanic. While both scheme against Team Flash, Clifford makes strategies while Marlize builds the inventions they rely on to keep up with the protagonists.

* ''Franchise/KamenRider'':

** ''Series/KamenRiderSaber'' has the three Megid leaders, Storious, Legeiel and Zooous. While Storious tends to be the one who plans things while Zooous acts as the muscle of the gang, the Megid don't really have a defined hierarchy between them, so the three are more-or-less on the same level. It's also revealed later that there's a secret Duumvirate that's been pulling the strings behind everything, [[spoiler:Storious and Isaac, the current [[EvilRunningGood leader of the Sword of Logos]]. More specifically, Storious was responsible for the fracturing of the [[AkashicRecords Great Book]] and the war of the Wonder World, while Isaac caused [[MysteriousWaif Luna]]'s disppearance, the corruption of Kamen Rider Calibur before the series began and the corruption in the Sword of Logos, all in the name of claiming the Great Book for themselves.]]

And, and, for a while, they also have the BrainwashedAndCrazy Rip Hunter]].

* ''Series/OnceUponATime'':
** Season 2: Tamara and Greg, until it's subverted and revealed that they were actually co-dragons under Peter Pan.

Russo is an associate who owns a private military company called Anvil and uses his men to help silence anyone who could expose the corruption Rawlins and Russo himself were a part of. While Rawlins' arrogance leads him to believe he is the sole BigBad who makes the plans, Russo is TheDragon who gets his hands dirty, it's clear by now its a partnership, which is shown [[spoiler: when Russo arranges Rawlins' demise upon realizing the latter won't hold up his end of the bargain]].
* In ''Series/ResurrectionErtugrul'', Karatoygar (Politician who leads the Seljuks) and Petruchio (Master of the Amanus Mountains Templars) have an alliance of some sort in the first handful of episodes of season 1 due to the Seljuks backing the Templars legally and threatening Ertugrul after Ertugrul rescues Halime and her family from a small group of Petruchio's knights. Later, Al Aziz (In charge of the Arabs in Aleppo) and Titus (The latter being TheDragon to Petruchio) are also shown to interact with each other and conspire against Ertugrul despite their differing affiliations.
** Season 2 does this with Noyan and [[spoiler: Sadettin Kopek once the latter arrives,]] working with one another to impede Ertugrul but neither man being truly subordinate to the other since they are associated with distinct entities.
** Season 5 has quite an elaborate one: it starts with Emir Bahaddin and The Mongols (The former being backed up by the latter during his tenure in Konya), and later [[spoiler: Albasti, who fills in the void after Bahaddin is dispatched]]. [[spoiler: ''Then'', Dragos becomes part of the villain network after Albasti makes an agreement with him to eliminate the Kayis]].

* ''Franchise/SuperSentai'':
** ''Series/HyakujuuSentaiGaoranger'': The Three Highness Duke Orgs all work as the leaders of the Org race as a whole, with Org Master being but a mere figurehead they made to serve as an idol to rule over the lesser Orgs.

** Season 2 has the Widows, a pair of demonic sister-wives, working in concert to resurrect and [[SealedEvilInACan free]] their husband Bulshar, the GreaterScopeVillain of the series. [[spoiler:At the end of the season, they're also joined by a [[BackFromTheDead resurrected]] Bobo.]]
