Chameleon (comics)
The Chameleon was born a Soviet citizen named Dmitri Smerdyakov (Дмитрий Смердяков). In his youth, he was a servant and half-brother to Sergei Kravinoff and eventually became a minor associate to Gustav Fiers. Although Dmitri and Sergei were friends, Sergei was often abusive to Smerdyakov, leading to a combination of admiration and resentment towards Kravinoff. Eventually, Smerdyakov emigrated to the United States of America. As he had made a talent for himself during his youth, impressing his brother by impersonating friends and neighbors, he assumed an even more impressive disguise: the identity of Chameleon. During his first known criminal outing, he impersonated Spider-Man, though he was exposed and arrested. Shortly afterward, Kraven the Hunter himself came to America, and the Chameleon set his old associate's sights on Spider-Man. Both men became long-time enemies of Spider-Man, part of his primary rogues' gallery.
Namaqua chameleon
Unlike the arboreal chameleons of the genus "Chamaeleo", its tail is not prehensile, but otherwise it still hunts in the same way, slowly stalking its prey and catching it with its long tongue. Namaqua chameleons feed on insects, (particularly beetles and crickets); lizards, including young chameleons of their own species; small snakes; and even scorpions. They hunt their prey in both sandy dunes and rocky areas.
In turn, Namaqua chameleons are preyed upon by jackals, hawks, and eagles. Similar to other chameleon species, in areas near human habitation, it falls victim to introduced predators such as domestic cats and dogs.
