Snake is a lean young man with golden eyes, short white hair with a distinct cowlick that trembles when he is nervous and straightens when he is startled, and pale skin interspersed with scales. He is always accompanied by at least one of his snakes. As the footman of the Phantomhive household, Snake dresses in a suit with a low vest and a ribbon in lieu of a tie. Previously, when traveling with the Noah's Ark Circus, Snake wore a high-collared jacket with baggy sleeves that covered his hands.
