Desert Mermaid

Brave Warrior is the femslash ship between Ariel and Jasmine from the Once Upon A Time and Disney fandoms.

Canon
Not long after Ariel came across a magic necklace that give her a pear of human legs and the return of her voice, as long as she wears it, Ariel makes her way to Agrabah in hopes to find Eric. Not long after she arrived in the desert kingdom, she accidentally gets herself in trouble when she takes a fork, unaware that it is stealing. She is pursued through the Agrabahn capital and cornered by the owner of the fork, who grabs her necklace as payment, in which causes Ariel's legs to revert back to a mermaid's tail. The man is shocked by her transformation and begins to call her a monster, but is stopped by the arrival of Princess Jasmine, who pays for the fork and demands the return of Ariel's necklace. When she gives it back to Ariel, the mermaid explains its powers briefly and why she's in Agrabah.

Fanon
While the ship is commonly focused on OUaT's version of the two, there are fans who use ship and its commonly used title with Disney's versions of them within the Disney Princess part of the Disney fandom, since the ABC television series has its own versions of the Disney characters and has a few traits from its series; and it being the live-action show that helped to trigger the ship in both fandom universes.
