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".
Chameleon (comics)
In "Spider-Man Noir", Dmitri Smerdyakov (a.k.a. The Chameleon) is depicted as a former Coney Island freak working for mob boss Norman Osborn (a.k.a. "The Goblin"). Like his mainstream counterpart, he has the ability to alter his features to imitate any individual, although this ability stems from his clay-like malleable features rather than any technological advantages. Osborn has him impersonate J. Jonah Jameson in order to eliminate Ben Urich and set a trap for Spider-Man. He was killed by Felicia Hardy when she witnesses him as Jameson killing Ben.
The Chameleon plays an important role in the "Sinister Six" novel trilogy by Adam-Troy Castro. He arranges for the escape of Doctor Octopus, the Vulture, Electro and Mysterio to form a new incarnation of the Sinister Six, coordinated by internationally-feared criminal Gustav Fiers (the Gentleman) who has often employed the Chameleon in past schemes. With the aid of the Gentleman's ward, Pity, a young woman with enhanced strength and speed that allows her to stand up to Spider-Man and the ability to generate a psionically-induced darkness, these men form a new incarnation of the Sinister Six to aid in the Gentleman's plan to trigger a global financial collapse (although the Six are only aware of the Gentleman's plan to destroy the American economy by generating an EMP in the middle of New York, unaware that he also plans to release a catalyst that would destroy ink and thus remove all physical back-ups of the lost data, as well as render the money the Six had been paid with little more than paper). During their first attack of a 'Day of Terror', where four of the Six take hostages at various points around the city (Mysterio posing as Electro while he and Pity steal the catalyst to draw attention from Electro's absence), the Chameleon takes an acting class at Empire State University hostage to make them run across a football field rigged with explosives, but he is taken by surprise by Mary Jane, who dismisses his plan as pathetic before catching him off-guard and forcing him to flee. When the time comes to trigger the EMP, although Fiers believed that he had the Six under control, he is killed by none other than the Chameleon, who disguises himself as Fiers' new driver so that he can find the plane where Fiers is storing his new material wealth (Fiers having 'sacrificed' most of his actual money to pay the Six or buy new goods that will become more valuable once money itself has lost all value); while dying, Fiers reflects that he was always able to see through the Chameleon's disguises in the past, but wonders if the Chameleon just "let" him see through those disguises until he was ready to strike. However, the Chameleon's plan to take control of Fiers' scheme is cut short when Doctor Octopus attacks the plane intending to do the same thing, followed by a fight between Doctor Octopus, Spider-Man and Pity that sends the plane crashing into the sea, with Pity and Octavius vanishing while the Chameleon is left hospitalized from hypothermia and near-drowning.
