History VillainTeamUp / WesternAnimation

* "[[Recap/HerculesTheAnimatedSeriesS1E44HerculesAndTheArabianNight Hercules and the Arabian Night]]", a crossover episode of ''WesternAnimation/HerculesTheAnimatedSeries'' with ''WesternAnimation/AladdinTheAnimatedSeries'' had Hades team up with a recently Jafar in an attempt to kill one another's arch nemesis by pitting them against one another. While it was a deadly alliance (the heroes almost killed each other), the heroes figure out they were being played and Hades drastically underestimated [[KarmicTrickster Aladdin]]'s wit, resulting in Jaffar's staff being broken and him being dragged into the Styx, becoming just another mindless soul swirling in eternity.

* A crossover episode of ''WesternAnimation/HerculesTheAnimatedSeries'' had Hades team up with a recently deceased [[WesternAnimation/AladdinTheSeries Jafar]] in an attempt to kill one another's arch nemesis by pitting them against one another. While it was a deadly alliance (the heroes almost killed each other), the heroes figure out they were being played and Hades drastically underestimated [[KarmicTrickster Aladdin]]'s wit, resulting in Jaffar's staff being broken and him being dragged into the Styx, becoming just another mindless soul swirling in eternity.

* In the episode of ''WesternAnimation/CourageTheCowardlyDog'', "Ball of Revenge", Eustace decides to take out Courage by gathering a group of villains from previous episodes in an alliance against that stupid dog (ignoring the fact that these villains have also endangered his own life in the past).

* ''WesternAnimation/AdventuresOfTheGummiBears'': Igthorn and Lady Bane team-up in two episodes to plan how to get rid of the Gummi Bears. Igthorn's crush on Lady Bane is a running gag, especially because is not mutual.

* ''WesternAnimation/TheVentureBrothers'' had Baron Underbheit consider an alliance with the Monarch in order to defeat Dr. Venture, only to be stymied by [[WeirdTradeUnion union bylaws]]... which they laugh at and plan on teaming up anyway.

** The page quote comes from the episode "Steal Wheels", where Dr Drakken and Motor Ed team-up. In this particular case the answer turns out to be 'because they're [[TalkingToHimself cousins]]'.

** The second-string ''WesternAnimation/TransformersAnimated'' villains Professor Princess, Angry Archer, Nanosec, and first-timer Slo-Mo team up to form the Society of Ultimate Villainy (SUV) in the episode of same name.
** ''WesternAnimation/TransformersPrime'' has had a couple of team ups involving [[TerroristsWithoutACause MECH]]. First, in "Crisscross", they allied with [[DarkActionGirl Airachnid]] in order to capture Arcee and Jack (Airachnid wanted revenge, MECH wanted the technology in Arcee's body). This ended when [[BigDamnHeroes Agent Fowler showed up with reinforcements]], and the villains fled separately. Then, in the "Operation Bumblebee" two-parter, they formed an alliance with [[spoiler: [[DangerousDeserter a renegade]]]] Starscream, who offered his knowledge in exchange for a share of the energon they'd need for their own plans. This lasted until [[spoiler: Silas got sick of Starscream, stole his T-Cog, and then ditched him]]. Then, in "The Human Factor", [[spoiler: Silas, having been grafted into Breakdown's corpse after he was traumatically injured, decides that MECH has outlived its usefulness and destroys his own followers. Then, he attempts to join the Decepticons; but when his plan to get them a KillSat fails, [[AssholeVictim Megatron decides to let Knock Out vivisect him]]]].

** Unlike other villain team ups however, these villains actually trusted each other (although some of them didn't get along very well) The only reason Tee betrayed them was because they all belittled him, and Zix and Travoltron only left because Tee convinced them to do so. Other than that, the only reason they lost was because Jimmy outsmarted them all one at a time.

* ''WesternAnimation/TheSmurfs'', Gargamel teams-up with another villain in at least one episode for season including Bigmouth, Balthazar, Hogatha and Nemesis, generally with unfortunate consequences... for him.

* ''WesternAnimation/ThePowerpuffGirls'':

** Alvin the Treacherous and Dagur the Deranged team-up too against Berk for a while but it doesn't take too long before [[spoiler:Dagur turns againts Alvin and took control of the Outcasts tribe.]]

* The final season of ''WesternAnimation/TeenTitans'' builds to a climax as the Brain leads a team up of nearly every villain in the show's run to capture the Titans and all their allies. Except the [[CrouchingMoronHiddenBadass harmless]] [[BewareTheNiceOnes ones]].

* ''WesternAnimation/TaleSpin'': [[CorruptCorporateExecutive Shere Khan]] and [[SkyPirate Don Karnage]] join forces in episode ''On a Wing and a Bear'' to cause an oil shortage.

* The 1987 ''WesternAnimation/{{Teenage Mutant Ninja Turtles|1987}}'' has the Rat King and Leatherhead teamed up to fight against the turtles in one episode. In "Night of the Rogues", Shredder hires the past villains (including the mentioned two) to eliminate the turtles.

* "Beyond Good and Evil", the four-part premiere of the second-to-last season of ''WesternAnimation/XMen'' has Magneto, Mr. Sinister, Mystique and Apocalypse teaming up together. However, Apocalypse initially lied to Magneto that his goal was to create a mutant utopia while his real EndOfTheWorld plans clash with Magneto's, thus causing him and Mystique to turn against Apocalypse. Mr. Sinister is all game with "let's destroy everything!" though.

* In an episode of ''WesternAnimation/CourageTheCowardlyDog'', Eustace decides to take out Courage by gathering a group of villains from previous episodes in an alliance against that stupid dog (ignoring the fact that these villains have also endangered his own life in the past).
