In the dialogue heavy clip, Stark breaks down the 'Avengers' team.
Your brother, the demigod. A super soldier, a living legend who kind of lives up to the legend. A man with breathtaking anger-management issues. A couple of master assassins. And you, big fella, you've managed to piss off every single one of us, he says in the clip.
Loki responds with I have an army.
Stark fires back. We have a Hulk. The clip ends with Stark promising that if the team can't protect Earth, then they will avenge it.
The exchange occurs in Stark's New York City apartment.
Along with the clip, two new TV spots have popped up.
The first one, entitled 'Isolation' shows the superheroes before they become a team.
The second TV spot, 'Suit Up' shows Black Widow escaping from her captors after a call revealing Arrowhead has been compromised.
'The Avengers' stars Chris Hemsworth as Thor, Chris Evans as Captain America, Jeremy Renner as Hawkeye, Mark Ruffalo as Hulk, Samuel L. Jackson as Nick Fury, Scarlett Johansson as Black Widow, and Robert Downey Jr. as Iron Man. Tom Hiddleston plays villain Loki.
'The Avengers' hits theaters May 4.
