Elsa

Elsa is the daughter of Agnarr and Iduna, the older sister of Anna and the former queen of Arendelle. She was born with the powers to manipulate ice and snow and, as a child, used them to entertain her sister. However, after Elsa accidentally hurt Anna with her powers and Anna's memories had to be erased, she grew afraid of her powers and was unable to appropriately control them. She lived in fear of hurting anyone with her powers, and spent much of her formative years shut out from the world. Although it pained her greatly to do so, Elsa also found it necessary to distance herself from her family so there would be no risk of causing further harm.

Anna enlisted the help of a man named Kristoff and a snowman Elsa accidentally gave life to named Olaf. They went on a journey to convince Elsa ro unfreeze Arendelle and to come back home to be Queen.

After her powers were exposed at the coronation, Elsa fled Arendelle, and found peace in being able to experiment with her powers whilst away from people she might harm. Ultimately, Elsa was able to rekindle her relationship with her sister after learning how to fully control and appreciate her powers.

While she and Anna have reconciled, their relationship is still growing and changing. so while Elsa may seek to guide Anna through most subjects, Elsa will tend to go along with what Anna wants when it's about rebuilding their bond.
