Baio looks almost indistinguishable from his brother, Boes. Both are of about average height, with the sort of athletic build that comes from everyday hard work, and both have short, dishwater-brown hair that looks perpetually tousled. The twins' hazel eyes glint with mischief, and they have both the playful demeanor and the bottomless appetites of adolescent boys, despite their obvious adult age.
