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.
Chameleon (comics)
Following the return of the true Spider-Man, Chameleon attempts to drive Spider-Man insane as revenge for the Superior Spider-Man's treatment of him during the events of "Superior Six". However, Spider-Man's ally Deadpool switches costumes with Spider-Man, with Chameleon unaware of this. He fails at driving "Spider-Man" insane (as Deadpool is already insane), and ends up being shot in the leg by him. Both heroes (in each other's costumes) punch the Chameleon at the same time, knocking him out and later delivered him to the authorities.
