Nine was a man of reasonable height with fair skin and thin, rectangular gray eyes and white pupils. He also had white hair that reaches just past his shoulders, worn swept back away from his face. In the past, Nine wore black shoes, black pants, and a tattered white jacket.

His most defining feature was the large black mask that covers him from his chest to just above his nose, four extra pieces winding around the exposed skin of his face and around his head. Four darker plates cover each side of his neck, lined with dark purple, and he had what appears to be something similar to the flat muzzle of a gas mask over his mouth that’s decorated with seven gray studs, as well as a large purple and black cylinder protruding from each of his shoulder blades. Below this, he wore a full-body suit of a similar design, with plates of black covering his entire body, leaving only his fingers exposed, and, over this, a blazer and dress pants of a pale lilac color. He also wore black boots.
