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

She should be the Antagonist

I would Cinta 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 lebih powerful.
Her main motive is set the whole of Arendelle on ice permanently, unfortunately her powers were remove sejak sisterly love.

She should be the Protagonist

She was possessed sejak an evil spirit and as mentioned, Anna and Elsa help their aunt to eliminate the evil spirit that gave their aunt the ice powers, thus reconciliation between aunt and her 2 nieces through love.
My saat theory is that maybe she could be the sumber for Elsa's powers, and since Elsa could control it, she is going to control her aunt's ice powers.


The Cold Never Bother Me Anyway!

So, here are my thoughts on whether the actual Ice Queen is going to make her way into the sequel.
