New trailer for "Iron Man 3" has made its way out via Yahoo! Movies, unleashing some never-before-seen scenes. It gives more look at the romantic relationship between Tony Stark and Pepper Potts as the brilliant industrialist gives his "great girl" a necklace and promises to protect her.

The tense situation is also highlighted with Aldrich Killian putting the fate of the world in Stark's hands. Meanwhile, bad guy The Mandarin gives Stark an ultimatum, "Do you want an empty life or a meaningful death?" Stark responds in his usual brash manner, "I'm not afraid of you... No politics here. Just good ol' fashioned revenge."

Preparing the impending big showdown between him and his big foe, Stark says he needs a backup and summons his "boys," which mean all of his Iron Man armors.

In the third installment of "Iron Man" film franchise, Tony Stark/Iron Man is pitted against an enemy whose reach knows no bounds. When Stark finds his personal world destroyed at his enemy's hands, he embarks on a harrowing quest to find those responsible. This journey, at every turn, will test his mettle.

With his back against the wall, Stark is left to survive by his own devices, relying on his ingenuity and instincts to protect those closest to him. As he fights his way back, Stark discovers the answer to the question that has secretly haunted him: does the man make the suit or does the suit make the man?

Shane Black replaces Favreau as the director for the Marvel Studios movie, set for a May 3 release in the U.S.
