As far as I know, most of Spidey's major villains (Green Goblin, Doc Ock, etc.) made thier debuts, like Spidey himself, in the 60's. The biggest exception to this would be Venom, debuting in the 80's. But I was wondering, which, if any villains debuted in the 70's?
I don't just want to limit things to the 70's though, basically, I just would like to know if there's a breakdown by decade of villains introductions, just to get a feel for the various eras, 60's through 00's.
I never expected so many responses. I don't have time to read them all right now, but I do plan to read them all at some point. Thanks.
