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.
Chameleon (comics)
The two encountered Chameleon at Peter's high school (Chameleon had murdered the principal and was posing as him), where Chameleon reveals that he wasn't human at all but a giant monster. Chameleon was finally defeated, however, after Spider-Man (of Earth 616) used Spider-Man 2211's helmet to literally "administer poetic justice", causing a last-minute body switch between Chameleon and Sandman's father into an electric chair.
