About the AUEdit
In this AU, the Big Four exist as characters within the folklore and world of The Book of Life.
Usually the characters have a run in with the characters of the story or are messed with the various gods of its pantheon. In other cases, the characters will meet as Calacas, souls that have passed on from the Land of the Living but live on in the Land of the Remembered, presumably fueled by the memories of those who knew of their legends and deeds when they were alive.
The Big FourEdit
Hiccup is seen as a Manolo Sánchez like character for the similarities between the two. Having fathers that have different plans for them, falling in love a strong girl which one of his friends also has an eye on, growing up without their mothers before reuniting with them as adults, refusing to kill what their families have be killing for years, taking a stand in the ring and believe to have honest hearts.
Since Jack is already a spirit he is portrayed as a Calaca.
Merida can be cast as Maria Posada, due to both their spirited & rebellious natures. Both are beautiful young women that value independence and freedom, knows how to defend themselves and would not hesitate to stand up for what they think is right.
Given his dark and imposing (and partially divine) origins and dishonest nature, Pitch Black is usually played as either an ally or a stand-in to Xibalba, ruler of the Land of the Forgotten.
Being the guardian of Memories and caring for both her fairies and the children of the world (and her mean right hook on Pitch) makes her La Muerte, the ruler of the Land of the Remembered. She can also be friends with La Muerte as she helps children to remember their past loved ones and childhood heroes.
Jamie, his little sister and their friends can easily serve as the Detention Kids. The children that Mary Beth told Manolo's story to. They can also be the children that live in San Ángel, Burgess can even serve or be used as a base for the Mexico town.
