Doctor Octopus

Doctor Octopus is, of course, a Spider-Man villain (he’s arguably the second most prominent one behind Green Goblin) and has already been portrayed on screen by Alfred Molina in Spider-Man 2.

In the comic books, he has actually led a Masters of Evil group, so if anyone is going to provide a Spidey link in an on-screen team, it should be him.

He’s a scientific genius and a major physical threat with his titanium tentacles and it would be cool to see him in a movie again – and it would be a refreshing way to include him if it was as part of a team.
