Yo is a tall, muscular young man with shaggy, unruly hair which is such a dark brown that it's almost black, sticking up in all directions around his head. His eyes are a loose diamond shape, warm brown in color, his bangs hanging low above them, and he usually has a smile on, whether it be nice or sinister. His hero costume consists of a gold jaw-guard that covers his cheeks, a thick green strap over each of his shoulders, attached at the front to two black plates with golden trimmings..
