Ozpin is a middle-aged man with tousled gray hair and thin brown eyes. He has a light complexion and sharp facial features. He wears shaded glass spectacles and a dark-green scarf with a small, purple, cross-shaped emblem on it. His outfit mainly consists of an unzipped black suit over a buttoned vest and green undershirt. He also wears black trouser shoes and long, dark-green pants.
