* ''WesternAnimation/TheJimmyTimmyPowerHour'': While the first two specials use the regular villains from ''WesternAnimation/TheFairlyOddParents'' and''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'', the third one, "The Jerkinators!", has Timmy and Jimmy create a new villain to fight; [[TomTheDarkLord Shirley]]. But things take a turn for the worse when Shirley steals Cosmo and Wanda's magic powers and Jimmy's intelligence.

* ''Franchise/{{KamenRider}} has far too many of these to count due to the yearly crossover movies starting in 2001.

* ''VideoGame/KingdomHeartsI'' started off as a fairly straightforward crossover game between various classic Disney franchises, with ''Franchise/FinalFantasy'' gameplay elements and character cameos. For most of the game, the classic Disney villains serve as an OmniscientCouncilOfVagueness and {{Arc Villain}}s of each world. However, towards the end of the game, TheManBehindTheMan is revealed to be an OriginalGeneration character: Ansem, the Seeker of Darkness[[note]][[KudzuPlot Future games complicate this a lot]], but don't worry about that for now[[/note]], setting up the MythArc for the series as a whole.

* In ''Crisis on Two Comics'', a crossover between Doc Glasgow's two comics ''Webcomic/EnnuiGO'' and ''Webcomic/BlackHole'', the villains are a tantric sex cult called the Gardeners.

However, it's revealed that their true intentions are much more sinister as members of their group are mysteriously disappearing and a member of Key Manati's diamond guard is caught as an infiltrator, thus inspiring Izzy to contact Diana Nox for her assistance. After the [[AGodAmI leader's]] [[LoveGoddess plan]] is revealed and the cult is defeated, they were sent away to Key Manati's prison, where Mother Rose implies that she may return to face the protagonists again.

* ''WesternAnimation/RugratsGoWild'': In this crossover between WesternAnimation/{{Rugrats}} and WesternAnimation/TheWildThornberrys, the closest thing the film has to a villain is the clouded leapard, Siri, who tries to eat the babies.

* ''WesternAnimation/TheJimmyTimmyPowerHour'': while the first 2 specials use the regular villains from ''WesternAnimation/TheFairlyOddParents'' and''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'', the third one, The Jerkinators!, has Timmy and Jimmy create a new villain to fight; [[TomTheDarkLord Shirley]].
