Treasure Planet AU

Treasure Plant 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 Disney's Treasure Planet. This could also be a sub-scenario for Pirate AU and Sci-Fi AU.

About the AU
Spawning from Fanart, this AU places the Big Four and other such characters as characters from Disney's Treasure Plant or the story that it is based on, Treasure Island.

Hiccup Horrendous Haddock III
Being good with his hands, bright, getting into trouble, wonders about the world outside his home and flies through the air, like he is apart of it, casts him as Jim Hawkins. A miniature Toothless or Sharpshot (the Terrible Terror he trained) can be cast as Morph.

Jack Frost
Being care free in the air, trouble and "had" kept to himself, casts him as Jim Hawkins. With Baby Tooth as a female, green Morph.

Merida DunBroch
Merida's red hair and strong female spirit easily casts her as Captain Amelia.

Hiro Hamada
Hiro is commonly portrayed as Jim Hawkins, as the two characters are both skilled with technology (Hiro made his own robot so he could join in the Bot Fights and Jim build his own Solar Surfer when he was eight), bright, know how to find trouble and they were betrayed by the men that they looked up to and trusted: Robert Callaghan and John Silver.

Robert Callaghan
With Hiro as the cabin-boy, Callaghan is cast as the pirate cyborg, John Silver. As Callaghan, he is the man that a young boy can trust, but as Yokai, he cares only for his "goal" and would stop at nothing to active it.

Cass Hamada
Cass Hamada is portrayed as Sarah Hawkins, with the Lucky Cat Café as the Benbow Inn.

Carl the Robot
Carl's form (and over the top panicking) heavily resembles B.E.N., the Bio Electronic Navigator.

Nod
Being fatherless, looking out for himself, finding and getting into trouble and being well skilled when it comes to flying through the air, heavily casts Nod as Jim Hawkins.
