The Sinister Six are a group of supervillains appearing in American comic books published by Marvel Comics, mainly those featuring Spider-Man. The members are drawn from the character's list of enemies, with the original members forming the team in The Amazing Spider-Man Annual #1. Led by Doctor Octopus, the team in its premiere followed swiftly the very early appearances of many of the most enduring members of Spider-Man's rogue's gallery: Vulture, Sandman, Electro, Mysterio, and Kraven the Hunter. While Doctor Octopus has generally remained its leader, the Sinister Six has had multiple variations of composition.

The Vulture is the alias of several supervillains appearing in American comic books published by Marvel Comics, most of whom are depicted as recurring enemies of the superhero Spider-Man and belong to the collection of adversaries that make up his rogues gallery, typically using special suits which allow them to fly at vast speeds.
