If Frozen were to be in Kingdom Hearts 3:
Maleficent could have a great influence over Elsa’s insecurity. Before the coronation, Maleficent could visit Elsa in her room where she anxiously awaits the ceremony. Maleficent is speaking to Elsa,trying to shatter her confidence by saying phrases such as; “You are not worthy,” “The darkness will overcome you,” and “Your powers can be used for a better cause.” Maleficent knows very well how powerful Elsa’s powers are and how she can use it to her own advantage, Maleficent want’s to use Elsa in her rise to power but Elsa is scared and starts to consider. The coronation begins, as Elsa is at the altar Maleficent speaks to her telepathically (Like in the original Sleeping Beauty: “Touch the spindle, touch it I say!”). Sora and the others arrive after the incident has happened as Anna is about to leave to find Elsa. They join her and Anna becomes a part of your team wielding a loot as her weapon. You make your way up the mountain and find Elsa, she is scared. Elsa tries to get them to leave and they keep refusing, they try to chase her down to talk to her but she is so afraid that either Elsa becomes the first Boss Battle (We know she can fight like with the guards and in Disney Infinity), they hesitate in fighting her at first but as she gets so angry, she pins Sora up against the wall with a sharp icicle up to his throat (like the guard in the movie), he says “You leave me no choice,” then the scene transitions into a boss battle. Maleficent is speaking to Elsa from the balcony, telling her to kill them and to rid light of this world ect. and Elsa is defeated. Maleficent stands over a fallen Elsa and says “You foolish girl, get up and kill them!” Elsa then refuses and shoots her with a blast of ice but Maleficent disappears in green flames before it hits her. Elsa then apologizes and joins the party. Either that or Elsa conjures up Marshmallow and then he becomes a boss fight.
Then the story continues.
This is amazing
