Background
Princess Anna is a member of the Royal Family (Whereabouts unknown) and the younger sister of Elsa.

Trivia

 * If Anna joins the Disney Princess franchise, she will be the first to have a biological relative as the film's villain. Snow White has a stepmother for her villain, and Cinderella has a stepmother and stepsisters for her villians, but neither are biologically related to them.
 * If Merida does not join the Disney Princess franchise, but Anna instead takes her place as the 11th member in that group, than she will be the second freckled and computer animated princess after Rapunzel. Otherwise, she will be the 12th member in the lineup.
 * Even though the animation has yet to be known, if she joins the lineup with Merida, she'll be the second to be in 3D. If Merida doesn't join, she'll be the first.
