Brave Warrior

Brave Warrior is the femslash ship between Mulan and Merida on ABC adventure series Once Upon A Time.

Fanon
The two were shipped instantly by many after the reveal that they knew each other. The fact that they were both Disney Princess' who were both best known for fighting helped, as well as the two meeting in a fight that Merida loses, followed by her smiling when it's revealed that she was defeated by Mulan.

The episode where the ship was created also created another ship for Mulan. Mulan Rogue, the ship between Mulan and Red Riding Hood. Although the two ships were technically against each other, there were no ship wars between the two. This was likely due to the small size of both ships. It was also most likely due to fans wanting Mulan to have a girlfriend since the reveal that she was either Bi or a Lesbian. Fans would have likely been happy either way.

The ship is the third most written ship for the Once version of Mulan, and the second most written ship for the Once version of Merida. Given the amount of works on AO3, many would consider it a rare pair.
