Calderon is tall, broad, and has neatly gelled blonde hair, fair skin, and dark blue eyes. His size is often described as "intimidating". He has a burn scar on the right side of his body that extends from just above his collar down his shoulder, and a tattoo around his right bicep that is comprised of three thin black lines circling his arm with a fourth, thicker line enrciling his arm below. He smells of clean soap and fresh linen.
