Based on what we’ve seen from ‘Avengers: Age of Ultron’ so far, it seems like Earth’s Mightiest Heroes may find themselves at odds with the incredible Hulk. I mean, that Hulkbuster armor is everywhere for a reason, right? The latest actor to step into the role weighs in on the internal battle going on inside the strongest there is while the team deals with James Spader’s Ultron and the various other troubles they’re set to face in Joss Whedon’s upcoming Phase Two film.

In an interview with Empire Online, Mark Ruffalo goes into great detail about what we can expect from his Hulk in the follow up to ‘The Avengers.’ Aside from talking about the new technology utilized to bring the mighty monster to life, addressing the possibility of another solo Hulk movie happening ever, and the Science Bros, the actor comments on the struggle that we find Banner facing within his own head that may manifest itself into an external battle with his teammates:

“Hulk is the kind of wild card. He’s the loose cannon of the group. He’s more like an atom bomb. You could guess where he’s going to go but he could go either way. I think that there is, obviously, the day when everyone expects it to go wrong and that day comes. And they’re ready. And Bruce designed the contingency plan. As much as you feel Bruce has some mastery over it – certainly, with ‘I’m always angry’ and he can turn into it at will – I still feel that there’s some part of him that doesn’t completely trust it and doesn’t completely trust himself.

There’s a battle going on between these two opposing egos that live inside him. He’s definitely worried that the day is going to come when the Hulk gets the best of him, and maybe won’t release him, maybe won’t give him back. The Hulk knows this too. There’s a moment in here where he, begrudgingly, decides to go back to Banner. Who knows where these things will go, but as Bruce is able to impress his will on the Hulk, going into The Hulk and being inside the Hulk when he’s raging, The Hulk’s will is also growing and able to impress upon Bruce. That makes for some wild things. We’re laying the groundwork for that here. It’ll be interesting to see if that ends up being what would be the next Hulk movie.”

There’s a good bit that we could take away from Ruffalo’s comments. First, he says that Bruce designed the contingency plan for whenever the Hulk goes out of control. Obviously, Tony Stark probably had a hand in it as well if it includes armor of some kind, but it’ll be interesting to see what sort of specifications the two brilliant minds came up with to stop the Hulk. Then, the actor says that both the Hulk and Banner’s wills are growing. Could that be confirmation of those Grey Hulk rumors that we heard recently? It’s a possibility.
