Galadriel

Galadriel was possibly the most powerful elf of her era, wielding incredible magical ability and unsurpassed beauty and intelligence. During The Hobbit: The Battle of the Five Armies, Galadriel rescues Gandalf from Dol Guldur and confronts the resurrected Nazgûl with Saruman and Elrond. She then shows off the height of her power in banishing Sauron back to the East as a giant fireball.
