Frozen Warrior

Frozen Warrior is the femslash ship between Mulan and Elsa from the Disney and Once Upon A Time fandoms.

Canon
As Elsa and Mulan are from different series, they have never met in canon. Even though there are a few Disney crossover medias that do have the two cross paths with on another, like Ralph Breaks the Internet. Where Mulan and Elsa are seen sitting close to each other while Mulan spoke, Elsa looks at her with a smile.

In their families both young women were told to be the perfect daughter and girl in the public eye. Before Elsa and Mulan left home in their first films, they forced to hide their true selves, in which later got them in trouble at Elsa's coronation and Mulan's meeting with the Matchmaker. At the end of them, however, the two were finally excepted for who they are. Their second films also have Mulan and Elsa bring people together. Elsa is an older sister while Mulan has a younger sister in the live action remake. They are also strong in their own unique ways and have been to snowy, mountain areas. The two are also friends with a small reptile that have power over fire. Mushu accompanies Mulan on her journeys, while Bruni joins Elsa half way through hers.

Even though the two didn't meet one another in the Once Upon A Time series, they were both were a bit hostile towards Emma Swan and Hook until they came to an understanding.

Fanon
While the ship is commonly focused on the Disney versions of the two, there are a few fans of the ship who use the Once Upon A Time versions of them. Modern AU's take inspiration from their clothes from Ralph Breaks the Internet. Just as Mulan is a lesbian in the OUAT series, there are fans who believe that Elsa is one as well, which helps to give the ship support.

Most fanwork of the ship have Mulan coming to Arendelle where she meets Elsa and her sister, as Mulan's warrior experience allows her to become the queen's bodyguard and friend. since fans see them bonding over the love they have for their fathers and pressure of leaving them. Along with Once Elsa helping Once Mulan to heal her broken heart, a few OUAT AU's have Mulan and Elsa meeting in Storybrooke.

On AO3, the ship has 8 fanfics in its Disney tag and 17 in its OUAT tag. While FanFiction.Net has 3 fics in its crossover category and only one in its OUAT category. The ship also has a small fanbase on Tumblr and DeviantArt.
