Spider-Man has arguably some of the best villains in all of comic book history and probably only Batmans and the X-Mens rogue galleries can rival Spideys. the Spider-Mans villains are very different and diverse. There are the more classic villains such as Dock Ock, Green Goblin, Lizard, Electro or Vulture and the more darker and serious villains such as Venom, Carnage etc. that symbolize a very different era. But which is one is your all time favorite?
I came to Spider-Man with the McFarlane/Michelinie era so my favorites will always be Carnage and classic Venom , closely followed by the Norman Osborn Green Goblin, because he and Peter have such an emotional and powerful relationship with each other. Plus the Goblin is so wonderfully crazy and diabolical Also love the Hobgoblin (who frightened me as a kid and always felt a bit darker and scarier than Green Goblin to me) and Dock Ock (as tentacled Ock, not Superior SM).
