Ugh, yeah, that was gross. The writer didn't even want that to happen because the original plan was for the twins to be Gwen's and Peter's, but they decided not to do that at the last minute. That story isn't referenced anymore, though.

Oh yeah, during the 90's they had those extreme villains like Doomsday, Bane, and Venom (or even Carnage). Doomsday was just a mindless monster, though, so they couldn't make him an anti-hero like they eventually did with Venom and Bane.
