This idea was inspired by Disney Heroes vs Villains, Non-Disney Heroes vs Villains, and Heroes vs Villains
This series is an inspiration of Disney vs Anime Villains were Disney hereos team up with Anime heroes to fight against the Disney villains and Anime villains.
I don't have to add a list of Disney films and TV series and Anime series and films this is just something that we can think of already.
In the Underworld Maleficent and Hades calls in Jafar, Yzma, Captain Hook, Scar, Dr, Facilier, The Archmage, Mozenrath, Aham aghoul, and Prince Phobos to discuse their plans to attack their enemies but are then interrupted by Queen Beryl of the Dark Kingdom of the Negaverse, who offered an alliance to rid all of the heroes which interest Maleficent while both Jafar and Prince Phobos are not sure if this is a good idea. Queen Beryl assembled all the villains through her crystal ball. Giovanni, Fieza, Cell, Him, Father (FMA), Kagetane Hiruko, Lelouch Vi Brittania, Charles, Vi Brittania, Naraku, Medusa Gorgon, Light Yagami, and Orochimaru, to merge with Maleficent's alliance. Maleficent agrees and both Maleficent and Queen Beryl are now leaders of the main villains alliance.
Pretty Cool isn't it?
Would anyone like to work on it?
