Here we have the third and final trailer for Avengers: Age of Ultron and it’s a doozy. In it we learn more about the origins of the superhero film’s big bad Ultron, who’s voiced by the incomparable James Spader. “I was designed to save the world,” snarls the A.I. And then: “There’s only one path to peace: their extinction.” Ultron was created by Tony Stark (aka Iron Man) as part of a project that would “create a suit of armor around the world.” Unfortunately, things went unexpectedly awry and he ended up “creating something terrible.”

Ultron’s plan? “We can tear them apart from the inside,” he brainstorms alongside Quicksilver and Scarlet Witch. Does this mean the new additions are playing for the wrong team, or is this all a trick? Regardless, the plan will prove fruitful since we’ve already seen The Hulk duke it out with Stark’s Hulkbuster.

Finally, there’s the tantalizing tease at the very end–our first look at The Vision, a popular superhero that Marvel’s been hinting at in its recent slew of movie posters. He’s played by Paul Bettany, the same actor who’s been voicing Stark’s home and suit A.I. J.A.R.V.I.S. Intrigue!
