The Chameleon (Dmitri Smerdyakov) is a fictional character, a supervillain appearing in American comic books published by Marvel Comics. Commonly depicted as a master of disguise and the half-brother of Kraven the Hunter, the Chameleon is known as being the first supervillain for Spider-Man to face by first appearing in the original issue of "The Amazing Spider-Man".
Juggernaut (comics)
The Juggernaut continues to feature prominently in Marvel titles, starring in an alternate universe adventure, battling Thor once again and starring opposite other characters such as the mutant team X-Force, Doctor Strange, the Hulk (allied at the time with master villain the Red Skull and tricking and capturing the Hulk with the same "civilian" guise used against Colossus), mercenary Deadpool, the villain turned antihero Venom, and multiple battles with the X-Men. The Juggernaut suffers a major setback during the "Onslaught" storyline, being defeated and then humiliated by the entity when imprisoned in the Gem of Cyttorak. The Juggernaut, however, eventually escapes.
