Standing at 5'8, Ahuatzi is tall for his people, with the dark brown hair and brown eyes typical of the Mexica. His broad shoulders and impressive musculature imply a life filled with hard labor, also evinced by his calloused hands and sturdy physique. His face is quite handsome and usually accompanied by a friendly, if slightly sly, smile.

He wears simple, utilitarian clothes, common to his people, and generally carries a backpack and a filled sack. A simple hand axe hanging from his backpack is the only visible weapon, and he doesn't appear to be wearing any armor.
