Has Tony Stark lost his touch? In this summer's Iron Man 3, we'll see a different side of the hero. The cocky and self-assured Stark is no more. His dangerous lifestyle has finally worn him down.

For Iron Man 3, Tony Stark (Robert Downey, Jr.) will take things down a notch. The witty and arrogant billionaire has changed his tune. After battling inter-galactic creatures in The Avengers, the hero was left shaken.

This May, Stark will return for a solo adventure. With no team support, his paranoia is at an all-time high.

Marvel chief Kevin Feige told MTV, "It's almost like post-traumatic stress: He really has retreated after the events of The Avengers into his workshop, where he's building advanced versions of his suits. He has [designed] a version of the suit that can latch onto him in individual pieces... anytime, anywhere."

Speaking of his armor, it's become a crutch. Stark doesn't leave home without it.

"As he starts to realize, it's basically because he doesn't want to be out of the suit: he's seen a lot of things in Avengers and has encountered a lot of powerful people, much more powerful than he is."

There's a pivotal scene in The Avengers where Steve Rogers questions Stark's skills and honor. He asks, "Big man in a suit of armour. Take that off, what are you?" We'll get the answer in Iron Man 3.

Feige continued, "Much of the movie is Tony in the middle of the country without his tools and a fairly broken suit to help him. But that's his superpower: he wasn't born on Asgard, he wasn't hit by gamma rays and he doesn't have the super-soldier serum. His power is his brain."
