The new Iron Man 3 trailer debuted on Yahoo! this afternoon, and we got that insight into the plot we've been waiting for. We also got a ton of quote-worthy lines. Shit's about to get real for Tony Stark (Robert Downey, Jr.).

Americans are now looking to the crime-fighting billionaire to protect them from The Mandarin (Ben Kingsley), but Tony's a little more reluctant than he has been in the past. "Things are different now. I have to protect the one thing that I can't live without. That's you," he says to Pepper (Gwyneth Paltrow).

The bad news is, it looks like The Mandarin is hell-bent on getting rid of Iron Man once and for all. "You don't know who I am. You'll never see me coming," he taunts.

Luckily, Rhodes (Don Cheadle) is ready to back Tony up as Iron Patriot. Basically, this looks epic.

Iron Man 3 comes out May 3.
