If they did redo Carnage, I'd still want it to be the standard (non buff chest piece) minimate with Venom's tendril attachments painted in the red and black color pattern.
My Spidey Villain list?
-Carnage (tendril and axe arm attachments)
-Hydroman (clear blue swap out torso and fist arms similar to Sandmans)
-Calypso (next to Shanna, the other nearly nude Jungle Queen)
-Paper Doll (could be a really neat sculpt or picture frame accessory with her crawling out of it)
