Daisy.and Minnie as Elsa and Anna

Since the sequel is coming out suivant year, here are my personal opinions whether another character with snow powers will be feature in the sequel and whether ou not shall will be the protagonist ou the antagonist.

She should be the Antagonist

I would l’amour to see Anna and Elsa having a wicked relative, who is actually their aunt and even has ice powers.But unlike Elsa's, their aunt's ice powers is plus powerful.
Her main motive is set the whole of Arendelle on ice permanently, unfortunately her powers were remove par sisterly love.

She should be the Protagonist

She was possessed par an evil spirit...
