Sonic Skull has a black suit covering his upper body with a green stripe in the middle and grey pants. He has green gloves and a green belt, as well as black boots with green soles. He wears green bones as ornamentation over his clothes, the broken up skeletal remains of creatures, which consists of:
- A ribcage on his chest.
- A tail bone on his right shoulder and a skull of a horned animal on his left shoulder.
