Beauty and the Beasts x Avatar the Last Airbender crossover

(As the title says, this is gonna be a Beauty and the Beasts crossover with Avatar the Last Airbender (with a little bit of Once Upon A Time). Only instead of Bai Qingqing, I'll be using an OC who originally came from Storybrooke, Maine and ended up in the Beast World before later ending up in the ATLA world along with the hawk beastman Muir while fleeing the City of Beasts after being exposed by the Ape King.
Also this is gonna be an AU where she actually manages to save the wolf beastman Shuu in time, because I don't like that he dies. So yes Shuu will still be alive in this crossover.

My OC
Amalia Snow Swan-Jones: the daughter of Emma Swan and Killian Jones, and younger sister of their canon daughter Hope Swan-Jones. She has long wavy dirty blond hair and hazel eyes, with a slight mix of both parents' personalities, and born with magic like her mom. She was born in Storybrooke, Maine, three years younger than Hope. One day she ends up falling through a portal to the Beast World, where she first meets the leopard beastman Parker after he saved her from being chased by wolves. And since then her life became pretty crazy with Parker and the snake beastman Curtis becoming her spouses, along with many other admirers who fall in love with her as well.

Disclaimer: I do not own Beauty and the Beasts or Avatar the Last Airbender, all characters belong to their respective creators. I also don't own anything from the show Once Upon A Time either. I only own my OC Amalia Snow.

Also this crossover will be set after the Ape King exposes her and she's forced to flee the City of Beasts after being sent with Muir.
