Every time I see threads like this, I weep at the fact Chameleon isn't a top contender for the greatest Spidey villian. On more than one occasion, this guy had storylines that could have propelled him beyond the likes of Ock and Goblin only to cop out in the end in some fashion by having some other villian behind it or having MJ or May defeat him.
This guy is a spy, right? Or was one? The things he could do to Peter's personal life would make killing Gwen look small. I mean this guy could look like anyone and instill Skrull-like parinoia (sp?) in Pete's mind. Next to Venom, and in some ways less than him he is perhaps the only villian to know Peter's ID (before civil war) and had little to show for it. I swear, in my little ideal world, Chameleon would have killed May and Raped MJ by now.
Voted Chameleon in the hopes he can be made credible some day.
