What is the twist going to be in the new Disney Mulan? She is trans and actually wanted to be a man all along. She identifies as male in the end.

Little Mermaid - she is actually mute and disabled. At the end she dies but we see her in a wheelchair in an assisted care facility. She was never a mermaid? It's deliberately ambiguous.

Lilo and Stitch. It is revealed in the end that she has a dog fetish. Yes, she is romantically attracted to the alien dog thing. It's a love story about animal rights and otherkin. She identifies as a cat.

Snow White. She has a split personality disorder. She was the evil queen / witch all along. This is implied toward the end when she serves apples for the dwarves and they fall asleep. She then sings a lullaby, turns to the camera and smiles menacingly.

I kind of want the beast to be a woman at the end though. It can send a message of tolerance
