Hobgoblin might be in it, but that would be the shittest movie ever.
Robot Master/Gaunt could be neat if done correctly.
I disagree with Cadbury, The Lizard could be awesome if they did it right and didn't make him a wuss.
Electro could be awesome.
Then of course there's Scorpion, Kraven the Hunter, and many more. Not all of the good villains are used up.
