Chameleon

Dmitri Smerdyakov is a master of disguise who debuted as Spider-Man's very first costumed foe. A bitter, identity-obsessed Russian spy and half-brother of Kraven the Hunter, he uses makeup, masks, and impersonation skills to infiltrate and deceive as the Chameleon.

Few villains can claim the distinction of appearing in the very first issue of The Amazing Spider-Man back in 1963, but Chameleon has that singular honor — a Silver Age original conjured by the legendary duo of Stan Lee and Steve Ditko at the very dawn of Marvel's web-slinging era. Over more than six decades of publication, this master of deception has proven remarkably enduring, racking up 128 catalog appearances and seven key issues that any serious Spider-Man collector will want on their shelf. Chameleon keeps dangerous company, sharing pages with the likes of Peter Parker, Kraven the Hunter, J. Jonah Jameson, and Otto Octavius, and his reach extends well beyond the main Amazing Spider-Man title into corners of the Marvel universe as varied as Spider-Man Noir and Spider-Gwen: The Ghost-Spider. If you want to understand the full, rich rogue's gallery that defines Spider-Man's world, Chameleon — one of its founding members — is absolutely where the story begins.
