Arielsa

Arielsa is the femslash ship between Elsa and Ariel from the Disney fandom.

Canon
As Ariel and Elsa are from different series, they have never met in canon. While the Disney crossover film that serves as the Wreck-It Ralph squeal, Ralph Breaks the Internet, has online versions of the two known as "netizens", the inhabitants of the digital made world that lies within the real-life internet. Where they are two of the fourteen Disney Princesses that are from the expo-like Disney website, Oh My Disney. In the film, after Ariel emerges herself from the water that she swam through so it could take the shape of a spiral, she joins Elsa on Jasmine's magic carpet the moment she lands herself on it; before the Disney Queen uses her ice magic to freeze the watery spiral into a slid of ice. As netizen Pocahontas uses the wind to safely send Ralph to a soft bed to land on, Ariel has moved from behind netizen Jasmine to the frost of Elsa before she begins to sing.

They are also two of the many Disney-based and owned characters in Once Upon A Time series, where Once Elsa had unknowing trapped Once Ariel in a bottle while she is trapping Blackbeard and his pirate crew in it as punishment for them trying to hurt Anna and Kristoff. Along with Ariel and Elsa being two for the Disney Princess characters who met Sora on their own home worlds in the Kingdom Hearts series, as well as both of them appearing in the same KH game, Kingdom Hearts III. Where Ariel is a featured as a summon character, while Elsa is revealed to be one of the new Princesses of Hearts, who were retitled as the New Seven Hearts.

Both Ariel and Elsa have fathers who are the leaders of their people and who want to keep their daughters safe, as they fear of the dangers that they might find themselves in, since Ariel has a habit of visiting the surface world and collecting items that fall into the sea and King Trident doesn't approve of it, while Elsa had lost control of her own ice powers as a child and King Agnarr had given Elsa a pair of gloves to help her conceal it until she is able to control it again. While Elsa has only one sister, that is younger than her, Ariel has six sisters that are all older than her, each one of their names begins with an "A". At one point in their lives, the two had lost their mothers while they were on/near a ship on the ocean.

Because Ariel and Elsa have two castles, one that resides close to the ocean and an other that is quite from them, as Ariel's first castle home is under the sea while Elsa's second castle home is on a mountain, they are seen as Disney Princesses that have two castles in their films. Even though Elsa is a Disney Queen who is viewed as a Disney Princess. The two have also worn a blue, sparkling dresses that were created from, one that is Elsa's signer dress, that she creates with her ice powers after she used them to build her ice palace, while Ariel's was given to her by King Trident after he turns her back into a human so she can be with Eric. For a brief moment in their Disney films they are seen on a rock that sticks out above the ocean's waves. In the prequel TV series of Disney's The Little Mermaid, Ariel has encountered many magical creatures that reside within the ocean, as well as her being a mermaid makes her one of them, while in the Frozen II trailer Elsa is seen encountering the Nokk a guardian that takes the form of a horse that is made out of water. Before Elsa's goes to take the Nokk's trail, she steps into the beach bear foot as she gets ready to run across the ocean's surface, while Ariel has walked bear foot on the beach around Eric's castle a few times.

Fanon
Elsa and Ariel are shipped by a small group of fans who believe they would get along very well. Along with the fact that both Disney Princesses are extraordinary, talented women. Elsa's ice powers and Ariel's beauty singing voice. Because Ralph Breaks the Internet is a canon Disney crossover, that has a version of the two know each other, the ship sometimes has them in the modern, casual style clothes that the netizen versions of them wear in the film. After the teaser and official trailers for Frozen II were realised and showed the scene of Elsa running barefoot across the ocean's surface, the ship became much more popular from the water related scene inspiring a few fans to write and draw Ariel helping or coming across Elsa after she falls into the water and encounters the mermaid instead of the Nokk.
