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.
Legion of Super-Heroes (2004 team)
Initial issues of this series reintroduced the characters and provided new and divergent origins for them. Most characters resembled their previous counterparts in costume and powers, with the most notable exceptions including Chameleon Boy, now called simply Chameleon and depicted as an androgynous creature, Star Boy, who in this version of the Legion is black, Colossal Boy, who is now a giant who shrinks to human size, and Phantom Girl, who exists in two universes at once and has conversations with people in her own dimension while talking to Legionnaires at the same time.
