Sandman? never heard of this one villain.
I know Shocker, Venom, carnage, rhino, the lizard( peters prof), mysterio, chameleon, Hob goblin, king pin, smithe, scorpion, vulture, hmmmmm cant recall any more.
But i never ever heard of Sand man
I would have thought that osborn would have become green goblin like his father,( like in the show and comics), but hollywood will probably spin it off as hob goblin though.
