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".
Charizard
In the "Pokémon Adventures" manga, Blue receives a Charmander from his grandfather Professor Oak. It evolves into a Charmeleon, and when Blue is possessed by a Gastly in the Lavender Tower, so is Charmeleon. Blue's Charmeleon is eventually released from its possession only to be faced down by an Arbok, owned by Koga. Charmeleon tricked Koga by using a zombie Psyduck to deflect Arbok's Acid before literally slicing the Arbok in half with his tail. Blue later appears with an evolved Charizard and gains access to Saffron City by helping to disable a barrier created by a Mr. Mime. Later, Red and Blue face off against Koga's Articuno and are frozen by its Ice Beam, but they ultimately defeat the Team Rocket Executive with Charizard's Flamethrower. It then teams up with Red's newly evolved Venusaur, Saur, and Green's Blastoise, Blasty, to defeat Sabrina's monster Pokémon. They end Team Rocket's control of Saffron City, splitting apart the three birds in the process.
