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.

However, the Chameleon was dealt a most humiliating defeat at the hands of Aunt May, when he attempted to trick her into believing he was Peter, then murder her. However, May was not fooled by any means, and defeated the villain with a plate of oatmeal-raisin cookies laced with Ambien. The Rhino was also employed as part of the team up and later defeated Spider-Man only to be unable to collect payment from Chameleon as he was already captured.
