Chameleon (comics)
Created by writer Stan Lee and artist Steve Ditko, the character first appeared in "The Amazing Spider-Man" #1 (March 1963), making him the first member of Spider-Man's rogues' gallery, based on issue publication date, excluding the burglar who murdered Ben Parker (Supercharger was the first Spider-Man supervillain chronologically). He is also well known to be related to Kraven the Hunter. That revealed relationship helped evolve him as a major villain compared to his original depiction of being just a solo villain in the original issue of "The Amazing Spider-Man".
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.
