Oh, I'm sure that Venom, Carnage, and "Battle-damaged-spidersense-half-masked-missing-shoe" Spidey would find their way into the set too! LOL But seriously, enough with the Venom, Carnage, Sandman variations!! (although I am actually really looking forward to the SM3 Sandman w/base and arm-aments. These should have been included with the first and only Sandman IMO...best idea ever.). I don't really even care if it truly does represent the "comic-accurate" Sinister Six, it's absolutely obsurd that considering what a "big Spidey fan" Chuck is, we don't have a Scorpion, Lizard, Kraven, Mysterio, Electro, Shocker, Vulture, Hobgoblin, etc. considering how many Spiderman have been produced.
Carnage had one minimate made of him, so you can't really say he's an overused character
