Princess Mononoke AU

Princess Mononoke AU is a popular AU (Alternate Universe) within the Rise of the Brave Tangled Dragons fandom. In the AU, Rapunzel, Merida, Hiccup and Jack Frost play roles from Princess Mononoke. This can be considered an offshoot to Studio Ghibli AU and Anime AU.

About this AU
Spawning from fanart, this AU places the Big Four, and other such characters in the fandom, as characters from Princess Mononoke.

Hiccup Horrendous Haddock III
Between Astrid and Merida as Mononoke, Hiccup is cast as Prince Ashitaka. As he leaves home (which he can not return to) with his Red Elk, Yakul (as Toothless) so he could lift the curse that is slowly killing and uncover the evil that gave birth to demon that attacked and cursed him; and "to see with eyes unclouded by hate".

His mother's history in the Dragon Sanctuary and his bond with dragons also give him the role of a version male of Mononoke/San. As a Prince of Dragons with Toothless as one of the dragons that raised him, in place of the wolves that had took San in as one of their own.

Jack Frost
For Jarida he's cast as Ashitaka (with brown hair) as he falls in love with the Bear Princess (when Merida is San) while trying to bring peace between man, the forest and it's spirits and gods. Since both characters have a younger sibling, Jack's little sister can be portrayed as Kaya.

Merida DunBroch
Merida is portrayed as the wolf princess Mononoke (also known as San), but as a bear princess. As she and her bear mother and brothers fight to drive the humans away and kill the 'evil woman' that command them to destroy their forest for iron and killed half of their "pack" and other innocent animals. Her necklace can serve as a green version of the Crystal Dagger, a parting gift from her human prince.

Her archery skills and being an older sibling can also cast her as a female Ashitaka. With Angus as Yakul, while one of her brothers is placed as a male version of Kaya.

Rapunzel Corona
Being strong in the face of danger so she could protect her friends, casts her as Ashitaka's younger sister and the former owner of the Crystal Dagger, Kaya.

Hamish, Hubert and Harris
The brothers and their mother are portrayed as San's wolf family (when Merida is cast as San and when the four play the roles in their bear forms), but older so their sister could ride on one of they're back's. While Elinor is a bear version of the wolf goddess Moro.

Will -O'-the-Wisps
The Wisps are portrayed as the Kodama, tree spirits that show as a sigh that their home and trees are pure and healthy. The Kodama also had helped Ashitaka find his way around their forest, much like how the Wisps had led Merida to the Witch's Cottage and the ruins of a ancient kingdom.

Astrid Hofferson
When Astrid is as San, she is given a dragon theme rather than a wolf theme and her Dragon Racing face paint can be used as San's war face paint.

Queen Elsa
Fans have cast Elsa as Mononoke/San. Sometimes with the wolves, that chased Anna, Kristoff and Sven, as her wolf family. As they both come from the film. Fans have even switched San's wolf theme with a deer theme, when Elsa is placed as a Reindeer Princess, due to Sven being placed as one of her animal siblings that she rides into battle. Elsa can even be placed as a female Ashitaka, for being an older sibling, leaving her home and taking on arrow wielding men, that wished to her harm.

Kristoff Bjorgman
Being a young man that rides a horned steed and racing into danger, so he could save the girl that he is in love with, can cast Kristoff as Ashitaka.

Valka
Valka is seen as a Princess Mononoke like character. As they both wear masks, wield sharp, staff/spear-like weapons and fights hunmans who wish harm on the animals that took her in. As well as paying respects and trying to protect the king of her home and harboring hatred towards the one that has caused so much pain.

Te Fiti
Since Te Fiti has two forms with two names and has power over the element of earth, she can be portrayed as female, humanoid version of the Forest Spirit. Her Te Kā self can serve as the spirit's Night Walker form and self, as after the spirit's head was taken during his transformation into his night form he began to spread death across the forest, just as the theft of her heart allowed Te Kā's curse to drain life from other islands.

Gothi
Since Hiccup is sometimes placed as Ashitaka and with Gothi being the wise elder of their people, can portray her as the Emishi elder Hī-sama.

Viggo Grimborn
Viggo's level head, his leadership and hunting skills, and being a businessman that has spilled blood for his goal and to make sure that they don't get in his way, can portray him as male version of Lady Eboshi of Irontown. As both characters changed their ways after being saved by what they had swore to kill. While being the leader of a band of bloodthirsty hunsters casts him as Jigo.

Trader Johann
First appearing as a friend before revealing himself as curl hunter, that would do whatever it takes to octane his prey, can easily cast him as Jigo.

Baymax
Baymax's white body and black eyes can easily have a miniature version of the healthcare-superhero robot as a Kodama.
