Yo is a muscular young man with unruly very dark brown hair, and diamond shaped eyes. His hero costume consists of a gold jaw-guard with green shoulder covers and grey front plates with gold trimmings. As well as black elbow pads, green wrist guards and black baggy pants paired with black boots. At first, Yo appears to be a friendly, social and kind individual. However, this "friendliness" proves to only be a façade that he puts on publicly. In reality, Yo is a scheming and calculating person.
