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".

The story begins five years after the events of "Pokémon Colosseum" with the introduction of The Hero, (default named Michael) the main protagonist. Michael talks to Professor Krane, his mother's boss, who introduces the concept of Shadow Pokémon, which are Pokémon whose hearts have been artificially closed. The criminal syndicate Team Cipher is creating and distributing them for their evil purposes. Krane also introduces the Snag Machine, which is used to capture Shadow Pokémon to purify. Krane entrusts Michael with the Snag Machine to capture these Shadow Pokémon and is given the Aura Reader (the eye piece) to identify them from normal Pokémon.
