Iron Man returns to fight villains, but this villain is different and stronger, scarier than ever.

The first trailer was released for Iron Man 3, which comes out in theaters in the U.S. on May, 3, 2012.

"I have a lot of apologies to make," Tony Starks starts off saying.

"Nothing's been the same since New York," he continues, referring to the events of "The Avengers." MTV News explained that he speaks over flashing images of the various characters in his life from best pal James "Rhodey" Rhodes (in his new, patriotic War Machine armor no less) to his new nemesis Aldrich Killian, played by Guy Pearce.

"You experience things, and then they're over," he says. "I can't sleep. And when I do, I have nightmares. Honestly, there's 100 people who want to kill me. I hope I can protect the one thing I can't live without."

The Iron Man 3 also brings back Tony's love interest, Pepper Potts, but she is rudely awakened by the arrival of an Iron Man suit even though Tony is sleeping right next to her.

"I am Iron Man. The suit and I are one." But maybe Tony spoke too soon.

"He (Tony Stark) basically loses all of his toys and is forced to just use his mind to rebuild and to face his biggest enemy. He's ultimately the engineering superhero," said Marvel's Kevin Feige, according to Examiner. "He's so charming and so flamboyant that sometimes you forget that's what he is: 'Hey, kids, learn this stuff and you can maybe build an Iron Man suit.'"

Entertainment Weekly said that director Shane Black borrowed some plot lines from Marvel's "Extremis" comic books, "in which Stark implants himself with sensors that allow the Iron Man suit to snap onto his body remotely. My guess is that when it can't just fly at him piecemeal as he stands before all the assembled parts, it assembles into a functional suit and seeks him out that way, perhaps in times of danger without him summoning it."

The Examiner gives the Iron Man 3 synopsis:

"Iron Man 3" pits billionaire, playboy, philanthropist Tony Stark/Iron Man 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?

This is not like any other villain Iron Man has taken on. The trailer has a dark feeling to it, like people are living in terrorism now.

HeroComplex reported that the Mandarin in the comics was "an exiled orphan who discovers a crashed spaceship. He mastered the alien science he found there and kept 10 powerful rings used to drive the ship. He used the rings' power in his schemes for world domination and became one of Iron Man's most formidable foes, from his first appearance in 1964′s "Tales of Suspense" No. 50, by Stan Lee and Don Heck."

In the trailer, The Mandarin (played by Ben Kingsley) says, "Ladies, children, some people call me a terrorist. I consider myself a teacher." A plane explodes and passengers fall from the sky. "Lesson number one: heroes? There is no such thing."

We hope that Iron Man can come through this time because he has shown himself to be a hero twice. Three times is the charm.
