"I was designed to save the world. People who have looked to the sky and see hope—I'll take that from them first. There's only one path to peace: Their extinction." It's the ominous beginning to the new Marvel's Avengers: Age of Ultron trailer. 

Now that S.H.I.E.L.D.'s gone, Tony Stark attempts to preserve the peace with a new A.I. program—Ultron. Unfortunately, it all backfires when Ultron comes to the conclusion that humans are the real villains and decides to, well, destroy all humankind instead. And once again, it's up to Captain America, Thor, the Hulk, Black Widow, Hawkeye and Iron Man to save the day—but it's too bad Ultron has other plans for the Avengers. 

Watch the trailer below. 

Avengers: Age of Ultron will be in theaters May 1 in North America. Two sequels, Avengers: Infinity War Part 1 and Avengers: Infinity War Part 2, are scheduled for May 2018 and May 2019 releases, respectively.
