So, I figured that maybe I should put together a list of some of my favourite fics and recs that are out there. This isn't meant to be exhaustive! Disney fandom is awesomely huge, and I only tend to see certain parts of it, at that. But without further ado, let's hit the recs!
This is always a work in progress, and new ones will probably be added with time.
Trust MeAladdin/Mulan, Jasmine/Fa Mulan
The AU where Genie really did make Aladdin a Prince, and Jasmine and Mulan meet, team up and save the day in the ensuing adventure. Adventure, action, fantasy, friendship. Minor femslash, minor het.
A Glass MoonBambi/The Little Mermaid, Ariel/Faline, Eric/OFC
Post-movie, Ariel begins to realise that she feels for women the way she should feel for men. Well-characterised, tentative, fluffy and sensuous both at once. Lovely writing. Romance, fantasy, character-centric. Femslash, minor het.
Picture ThisBeauty and the Beast, Belle/Gaston
A fic which develops them to get them together (and happily!) without breaking their characters. Some great moments, and characterisation which is complex and wonderful. Romance, mundane, worldbuilding. Het.
No Prince CharmingEnchanted, Giselle/Nancy.
AU where Nancy is the one who rescues Giselle. Sassy, fun and with a great voice. Romance, humor. Femslash.
TempestFrozen, Anna/Elsa (unrelated)
Elsa is the warrior Ice Queen of the Southern Isles, adopted by the King and enthroned at age 16. After conquering Arendelle, she takes Anna as hostage and advisor both. Plotty and well-developed. Fantasy, adventure, romance, magic, mild horror. Femslash.
Through Ice and ShadowsFrozen/Rise of the Guardians, Elsa/Jack, Elsa/Pitch Black
Elsa is a winter spirit, the Snow Queen, taken in by Pitch Black when her world seemed bleakest. Jack does his best to bring her back. Magic, adventure, romance, magic. Het.
UntitledHercules, Hercules/Megara
Darkfic. The story is all in Herc's head, and Megara is an unwilling participant in his fantasy. Modern AU, mundane, horror, psychological thriller. Het.
Black VelvetThe Little Mermaid, Ariel/Eric, implied Ariel/Ursula
Modern AU. Ariel is a country girl longing for the big city, but when Ursula offers to help it is only to make Ariel an exotic dancer in her club. Romance, dark, mundane, worldbuilding. Het.
The River SerpantMulan, Mulan-centric
Darkfic. Mulan protects China from the Huns even beyond the grave. Fantasy, magic, adventure. Gen.
Once Upon a NightmareSleeping Beauty, Aurora-centric
True Love's Kiss doesn't quite work out, and Aurora has to break her own curse. Adventure, family, magic. Gen.
