Sephiroth is a tall man, standing at 6'7 with a muscular build. He has long silver hair and bright cyan cat-like eyes. His signature wardrobe is a long black coat with silver pauldrons, black boots, and black trousers. The top of his coat is open to reveal his chest, with his leather SOLDIER suspenders crossed over it. He's calm, cool, reserved, well-spoken, graceful, and maintains a professional demeanor. Though, he can be extremely cold at times.
