She is the older sister of Princess Anna and the next in line for Arendelle throne, until her powers over ice and snow led her to become the famous Snow Queen, ruler of winter. Elsa is most iconic being the Snow Queen, and as such, she has complete and total control over the element of ice and snow. With her abilities (that she was apparently born with), Elsa can conjure up various things from snow flurries to blizzards. Most of her powers are unleashed via her hands, and controlled by her emotions.
