Queen Elsa of Arendelle (also called the Snow Queen) is the deuteragonist of Disney's 2013 animated feature film, Frozen. She's the ruler of Arendelle, and the older sister of Princess Anna. Her powers over snow and ice finally led her to become the renowned Snow Queen. Idina Menzel voices her. Elsa is broadly based on the title character of "The Snow Queen", a fairy tale by Hans Christian Andersen, and to a considerably lesser extent, Kai from an identical narrative. Elsa was rewritten as the deuteragonist while the character from the first fairy tale was unbiased and, to some level, villainous.
