1~Rotten To The Core

Elsa Winters, the baddest/evilest girl in the trashy island 'Sudope'. She and her best friends, Hiccup Haddock, Merida Dunbroch, and Anna Summers, have been transferred to this new school in the kingdom of Gardenia. With the past of evil and darkness running through their veins, they don't make much friends until the charming Jack Frost come along.

Will evil and darkness continue to run through their veins or will goodness stop it?

Based on the Disney Movie, Descendants.
