"The Avengers" Villain is The Hulk?

Every Marvel Film is leading up to the eventual team-up of Iron Man, Ant-Man, Thor and Captain America in the upcoming "The Avengers" movie. But what villain could possibly go up against such a powerful team?

Earlier, "The Incredible Hulk" director Louis Leterrier told MTV News that he didn't think that any villain could, and instead suggested to use The Hulk instead.

Now, "Iron Man" writers Mark Fergus and Hawk Ostby sat down with MTV to explain why they couldn't agree more. "I hope 'The Avengers' embraces that," Fergus said of having the Hulk as misunderstood bad guy. "You don't want like 10 super-badass good guys fighting together. Where's the fun in that? Let's break it off a little. Friends or colleagues who become enemies is always an interesting thing because you know it's based on love and friendship and that's always the worst thing to have turn bad — is someone you actually care about and someone you actually believe in."

Hulk, of course, has fought nearly every Marvel hero at some point in the comics, and because he already had his own movie, wouldn't need to be set-up in the new one. "I left the door open for whoever's going to direct 'The Avengers' with our last shot. Edward [Norton] and I, we consciously decided to make the last shot of the movie when he opens his eyes and he smirks at the camera," Leterrier told us. "Is he enjoying it? Is he malicious?"

Also, Robert Downey Jr as Tony Stark appears with General Ross at the very end of "Hulk" to discuss the green menace, a scene Leterrier called the first scene of "The Avengers."
