Mermaid Beauty

Mermaid Beauty is the femslash ship between Ariel and Belle from the Once Upon A Time and Disney fandoms.

Canon
Ariel met Belle when Mr. Gold (A.K.A. Rumpelstiltskin) sent the mermaid to Storybrooke, with the task of finding her so they could find a powerful item for him.

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 or had helped to make it popular in both fandoms.
