Zootopia AU

About the AU
Spawning from fanart, this AU places the Big Four, and other such characters in the fandom, as the animals living in the city of Zootopia or portrayed as characters from the film.

The four can also help Judy and Nick with the ZPD's tuff cases.

Hiccup Horrendous Haddock III
For the Hijack pairing, made the world a better place for both Vikings and Dragons, being the first to ride a dragon and is willing to try, casts him as a male Judy Hopps. But with brown fur, to match his hair. Dragon Root can serve as the Night Howler flowers, as it can make dragons go savage over it, like how the drug form flowers made predators go savage and attack other animals.

Jack Frost
For the Hijack and Jelsa pairing, fans have cast Jack as the fox con artist, Nick Wilde. But with white fur instead of orange, making him a snow fox and to make his "fur" match with his white hair. Jack can also be a winter or artic animal (like a Snow Wolf or a Polar Bear) living in the Tundratown district of Zootopia.

Rapunzel Corona
Hanging onto her dream, blackmailing a man into helping her and becoming close with him, casts Rapunzel as Officer Judy Hopps; and Flynn as Nick Wilde.
