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.
Legacy hero
One of the best examples exists in Disney's "Gargoyles", as a multi-generational line of villains known as the Hunter, originates with the TV series' fictionalized depiction of the historic Gille Coemgáin of Moray as a boy. The young "Gillecomegain", as he is known within the series' storyline, is confronted by the evil female gargoyle Demona and slashed by her on his face, and the trio of slash wound scars on Gillecomegain's face, carried by him for the rest of his life as he seeks his revenge on the female gargoyle, becomes part of the "Hunter" disguise for succeeding examples of the Demona-hunting antagonists.
