History Fanfic / DisneysWarACrossoverStory

* In ''The Final Adventure — A Disney Crossover Finale'', the Master of World has finally succeeded in uniting the worlds together into a single one. Thanks to a potion that Mary Poppins made her drink before the merging, Merida still remembers the original worlds clearly, but a CosmicRetcon has changed the history of the now single World and of its characters, who however retain a small glimpse of their former lives in dreams. The problem is that the interference of the stories has changed the course of the heroes' history: captain Jack Sparrow freed Aladdin from prison before he met the old prisoner who led him to the lamp, Shan Yu, thanks to external help, as conquered China and made it into the Hun Lands, and Minnie never married Mickey who remained captain of the musketeers. Merida finds the Master of Worlds masquerading as Lord Arawn, king of Prydain, but discovers he's only a pawn on the chessboard of another, far more powerful Master…

The fanfics take place in a very elaborate version of what a Disney Multiverse could be like: it has its inner balance, each world being a new branch to a metaphorical "tree" of which the "Center World" is the trunk. The Center World is a medieval-fantasy-themed utopia where the [[WesternAnimation/ClassicDisneyShorts classical characters such as Mickey, Donald, Goofy, Clarabelle, and Yen Sid]] live. To study other worlds, Yen Sid, who is King Mickey's adviser, has created the Doorway, a [[ExactlyWhatItSaysOnTheTin magical doorway]] that allows people to travel to other worlds, and the Viewing Basin, in which Yen Sid can see what happens in various worlds and write it down in the [[GreatBigBookOfEverything Book of Legends]] that he created.

Soon, the worlds lose their precious balance, and things start to revert to the way they were ''before'' the stories happened: Ariel goes back to being a mermaid, and the Prince/Adam turns back into the Beast. Meanwhile, the Horned King is perfectly aware of the danger of the worlds being destroyed, but it suits his great purpose: he wants to be a god, and once the worlds are destroyed, he thinks he'll be the one to rebuild them to his image. Mickey and the gang, realizing the threat of the King, start to gather the heroes of every world in their world. But since the Doorway is now unusable because of the lost balance, they have to use the more archaic portal spell, which heavily drains on the user's life-force. And Yen Sid's health is deteriorating…

* UnwittingInstigatorOfDoom: Goofy allows a [[PaperThinDisguise clearly-suspicious looking man]] into the castle after making sure all of the feast guests were allowed to enter. Shortly after, said man turns out to be Pete, who steals the Book of Legends and heads off to Prydain after learning about the Black Cauldron's power. Keep this in mind: ''[[NiceJobBreakingItHero the entire plot has happened all because Goofy didn't pay close attention to who the uninvited guest was.]]'' Then again, see YouCantFightFate below.
* UtopiaJustifiesTheMeans: Invoked by the Master of Worlds when he kidnaps Rapunzel, Ray, the Spring Sprite and a few more.

* NiceJobFixingItVillain: Scar inadvertently, but subtly lets slip on where he and the other villains are located.

** Jaq and Gus didn't do much, but they ended up saving Cinderella from Gaston when he held her at knifepoint during the climax, which led to his demise.

* AdaptationalHeroism: In a sense; in the new world created in ''Final Adventure'', Jafar, Hans, and Arawn have become the 'heroes' as far as the public is concerned, but Merida soon confirms that they're still the villains she heard about in the original history.
