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.
