Characters / Spider-Man: Rogues Gallery

"One type attracts another, similar type. Gods against Gods, patriots against people who think they're patriots, mutants against mutants. The kind of enemy you get tells someone a lot about the kind of person you are."
Ezekiel Sims, The Amazing Spider-Man Vol. 2, #32

Possibly the most famous rogues gallery after Batman's, this page details many of the nefarious do-badders that Spider-Man has squared off against. (Thought not all of them just yet, unfortunately.)
