I was thinking about the plot of the Avengers movie, and what they would do. So I've came up with a rather nice theory as to what would be massively awesome. I thought about each baddie from the main films we've had, and will have.

Hulk had Abomination and anybody clever enough would have noticed The Leader aswell. Iron Man also cleverly introduced the The Mandarin in the background. Fantastic Four had Doctor Doom, Thor will have Loki, Captain American will have Baron Zemo yadda yadda yadda.

All of which, have been in in the Masters Of Eeeevil. Would that be too ridiculous? The price for the cast alone would be huuuuuuuge, but it would be worth it for such an amazing old school load of baddies in a secret location doing nasty bad things.
