Sif has long black hair and dark, perceptive eyes. She had a great desire to be a Valkyrie but since they were killed long before, she became the only remaining female warrior on Asgard. She is heavily assertive, dominant, confident and independent, loud and aggressive like any male Asgardian warrior, riding, drinking and fighting like them. Her only feminine interests are taking care of her body, especially her hair, and woe be to the one who suggests cutting it short in any way.
