While The Avengers, X-Men, and Fantastic Four all have some iconic adversaries, there are few Marvel superheroes out there that have a rogue's gallery on nearly the same level as Spider-Man. Indeed, Spider-Man has continued to face off against some now-legendary foes, ranging from animal-themed villains like Scorpion, Rhino, and Vulture to more grounded villains like Kingpin and Tombstone, and a bunch in between.
