Chameleon (comics)
Following the "Dying Wish" storyline, Chameleon later fights Superior Spider-Man (Otto Octavius's mind in Spider-Man's body) and the Secret Avengers on the S.H.I.E.L.D. Helicarrier. Chameleon ends up knocked unconscious and Superior Spider-Man transports him to his hidden underwater lab where he ends up imprisoned. Chameleon, Electro, Sandman, Mysterion, and the Vulture are later seen as part of a team led by Superior Spider-Man called the "Superior Six". Superior Spider-Man has been temporarily controlling their minds in order to redeem them for their crimes. He does this by forcing them do heroic deeds against their will which almost get some of them killed. Every time he is done controlling them, he puts them back in their containment cells. They eventually break free of Superior Spider-Man's control and attempt to exact revenge on the wall-crawler, while nearly destroying New York in order to do so. With the help of Sun Girl, Superior Spider-Man is barely able to stop the Superior Six.
List of Spider-Man (1994 TV series) characters
Chameleon was an international hitman and spy. He also cannot (or does not) speak while he is in his true form, though his grunts were once provided by Jim Cummings. Though in the episode "Framed" Richard Fisk indicates that Chameleon told them about Peter Parker's parents. Chameleon has a belt, which is capable of capturing an image of a person, so that he can turn into a person to disguise himself, and then makes a perfect imitation of his disguise's voice. In his first appearance, he attempts to kill two diplomats at a U.N. conference to start a war, but is foiled by Spider-Man who easily picks the Chameleon out from the crowd since he had taken the appearance of Peter Parker, secretly Spider-Man's alter ego. In "The Insidious Six" and "Battle of the Insidious Six", Chameleon became a member of the Insidious Six. In "Framed" and "The Man Without Fear", he was working for the Kingpin's son, Richard Fisk in framing Peter Parker for getting restricted government information. But Parker's name was cleared by the machinations of Spider-Man and Daredevil, thus Richard and the Chameleon were sentenced to jail. Later, in "The Cat", it was revealed that he was jailed in S.H.I.E.L.D. for his dangerous international activities and he was assigned by the Kingpin to release Felicia Hardy's father. Chameleon was infused with a techo-organic virus prior to his incarceration in S.H.I.E.L.D., which made him part-machine and was able to change into any person without the belt. He successfully disguised himself as Felicia's father so no one would know the real Hardesky was abducted. Eventually, his ruse was uncovered by Nick Fury. Later, in "Six Forgotten Warriors" parts 1-5, he was rescued by the rest of the Insidious Six and became a member again, but would betray them and join forces with his foster father, the Red Skull (they have no relation in the comics), and his brother, Rhienholdt Kragov, who would later become Electro. In the end, Electro and the Red Skull, along with Captain America, were trapped in a time dilation loophole and the Chameleon escaped, never to be seen again. However, he was trapped by Spider-Man and webbed. The Chameleon was presumably killed, when the Doomsday Weapon was destroyed once and for all. It was not mentioned that he escaped from the reactor room.
