Zartan GI Joe Hall of Heroes 9 of 10

ZARTAN can alter his skin color at will to blend in with his environment. He is also a master of make-up and disguise, a ventriloquist, a linguist (over 20 languages and dialects), an acrobatic-contortionist and a practitioner of several mystic martial arts. Very little is known of his background and origins, but most security agencies agree that he must have had European military academy training (probably St. Cyr).
