Queen Elsa of Arendelle is the main heroine of the Disney's animated feature film Frozen. The elder sister of Anna and the next heir of the kingdom of Arendelle, Elsa was bestowed with icy powers from an early age, incapable of controlling them to the full. To that end, she hid most of her powers, and isolated herself from the others. Ultimately, she would return to her senses with the help of her sister and her newfound friends, and restore order in her kingdom. Elsa appears in the second Disney Heroes vs. Villains and Heroes vs. Villains wars as one of the prominent fighters of the hero forces in the CG realm.
In Heroes vs. Villains Tounament, it seems that she would be tagged with Jack Frost, a young teen with the same powers as Elsa, and she would develop a friendly relationship in the later events.
