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.
Question (comics)
The Question's specialized belt buckle, which releases a binary gas that binds his mask to his skin and temporarily recolors his garb and hair, is similar to that of the Spider-Man villain Chameleon. In his initial appearances, which were drawn by Steve Ditko, the Chameleon had used a device in a belt buckle which emitted a transformation-enhancing gas. The binding element is adjusted to Sage's specific body chemistry.
