Una is a character from He-Man and the Masters of the Universe.
Una is a beautiful young lady with black hair. Her outfit resembles a gold-on-white one-piece bathing suit with short puff-sleeves and a red bottom. She also wears red boots with a matching headband.
Una is a formidable magic-user, as is her brother Aran. While working for Skeletor, they put on golden masks and became vessels through which the evil sorcerers Deemos and Tyrella returned to life. When the Sword of the Ancients merged with He-Man's Power Sword, Una and her brother were restored to normal and left Snake Mountain with He-Man and Man-At-Arms, saying that they did not want to serve evil masters any longer.
