Chameleon (comics)
Following the return of the true Spider-Man, Chameleon attempts to drive Spider-Man insane as revenge for the Superior Spider-Man's treatment of him during the events of "Superior Six". However, Spider-Man's ally Deadpool switches costumes with Spider-Man, with Chameleon unaware of this. He fails at driving "Spider-Man" insane (as Deadpool is already insane), and ends up being shot in the leg by him. Both heroes (in each other's costumes) punch the Chameleon at the same time, knocking him out and later delivered him to the authorities.
