Spider-Man might have the coolest villains of any hero. Rivaled only by maybe @Batman, Spider-man’s rogue's gallery has some iconic characters. Arguably characters like @Venom, @GreenGoblin and @Mysterio are just as interesting as Spider-Man, and fans were willing to follow these villains into the comic book panels of other heroes. It must have been awesome reading @DareDevil only to see @Kingpin pop up and start getting in DareDevil’s way, the same he did to our favorite web-slinger. But which of Spidey’s reckless rivals took on a second helping of hero? We thought we’d make a list of some of the most interesting Spider-Man villains that fought some other other heroes behind Spider-Man’s back.
