Kingdom Hearts/Ships

= Axelsa = 

Axelsa is the het ship between Axel and Elsa from the Kingdom Hearts fandom.

Fanon
This crossover ship started long before Kingdom Hearts III was released, and revealed that Frozen has been added to the ever growing KH universe. That is why Axelsa is considered a KH ship as well as a cross ship. Most of the ship's support comes those who feel drawn to "Fire x Ice" couples. Lea's Axel persona is mostly featured in the ship, even though some have argued that Lea and Axel have been shown to be the same person than two separate people.

= RiElsa = 

RiElsa is the het ship between Riku and Elsa from the Kingdom Hearts fandom.

Fanon
Much like Axelsa, the ship between Riku x Elsa began long before Frozen was added to the Kingdom Hearts universe, through KHIII. That is why RiElsa is somewhere between a KH ship and a crossover ship. The only other female Disney character that Riku has been shipped with so far was Maleficent, but the age gap between them has people ship them as friends. That is what makes RiElsa unique among Riku het ships, since his friend Sora is mostly the one to be shipped with the Disney characters that have appeared in the franchise.

Those who wanted Riku to visit the KH world of Frozen, have centred around the same common idea that is mostly based on Dream Drop Distance. By having Riku be part of Elsa's story after she ran away from Arendelle, while Sora joins Anna in her journey to find Elsa. Seeing Elsa cut herself off from those she wants to protect and the darkness coming from her fear, Riku saw himself in her and wants to ensure that Elsa doesn't make the same mistakes he had made. Along with wanting to ensure that she doesn't fall into the darkness, like his enemies would want her to. Even though this didn't happen in the official KH3 game, some fans had liked the way that Sora had paralleled Elsa with Riku.

= Rikucent = 

Rikucent is the friend ship between Riku and Maleficent from the Kingdom Hearts fandom.

Fanon
The large age gap between Riku and Maleficent is the main reason people would rather ship them as friends than lovers. Maleficent telling Riku that saw him as a son in order to keep him loyal to her, however, had inspired another group to ship them as mother and son.

Fandom
= Tyaqua =

Fanon
Although the Monsters, Inc universe was added as one of the many worlds within the Kingdom Hearts universe, Tyaqua is still viewed as a crossover ship. With Tylor being part of the Monsters at Work TV series than the Pixar film that began the franchise, and was referenced in KHIII. There weren't any pairings with the protagonist

The ship was introduced by user thaliasonata, whom she also created Sullieta on DeviantArt, some people supporting this ship mostly on DeviantArt. The creator even made a fankid between the couple, turning her the favorite.
