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.
Dave the Chameleon
Dave the Chameleon uses the chameleon's ability to change colour to mock the Conservative Party leader. They aim to show that Cameron will 'change his colours' to fit the opinions of the people he is speaking to at a certain time. The Labour Party claim that this is a trick to hide his conservative values from others. This is part of a longer campaign to portray Cameron as an indecisive populist – indeed, John Prescott had used the term 'Chameleon' to describe Cameron some two months previously.
