Chameleon (comics)
Created by writer Stan Lee and artist Steve Ditko, the character first appeared in "The Amazing Spider-Man" #1 (March 1963), making him the first member of Spider-Man's rogues' gallery, based on issue publication date, excluding the burglar who murdered Ben Parker (Supercharger was the first Spider-Man supervillain chronologically). He is also well known to be related to Kraven the Hunter. That revealed relationship helped evolve him as a major villain compared to his original depiction of being just a solo villain in the original issue of "The Amazing Spider-Man".
Camouflage (novel)
Chapters alternate between the stories of the changeling and its various lives over decades; of Russ's attempts to decipher the artifact; and of the chameleon, whose story begins in Eurasia in the Pre-Christian Era. The chameleon "was always a man, and usually a brute." He can change his looks in a moment (unlike the changeling, who needs several minutes and suffers while doing so). The chameleon has often been a soldier, fighting for example with Alexander the Great and as a Masai warrior, though he also lived as farmers and butchers, among others; he suffers as a slave brought from West Africa to the new America, but in later decades makes a vast fortune.
