Part of my Disney Princesses as Villains series Moana personally I think this one of my best
Moana a girl who longed to travel the sea, have all sorts of adventures only to find pain, tragedy and heartbreak. On her quest to return the heart of Te Fiti beside the Demi God Maui a new monster was unleashed on the world. In a last ditch effort to return the heart and restore the world they doomed it when they inadvertently killed Te Ka. They found out too late that Te Ka was in fact Te Fiti thus all their efforts were for naught as the heart was shattered cursing Moana as the new Te Ka to lay waste to the world and her first act in this miserable existence was killing Maui. She remembers every cruel sin she commits trapped in this cruel cage with no control over her actions descending into deep despair.
