Thanos wants to teach The Avengers what it’s like to lose.

The Avengers — and by that, I mean every single Avenger we’ve encountered throughout the past 10 years’ worth of Marvel movies — have assembled. And the first trailer for Marvel’s Avengers: Infinity War has finally arrived.

Infinity War‘s trailer begins by outlining the plan for The Avengers — assembling Earth’s mightiest heroes — and then showing how Thanos is going to tear it apart.

“In time, you will know what it will be like to lose” Thanos (Josh Brolin) says, before shots of his invasion on Earth and him pummeling Iron Man.

Then we get a shot of Wakanda, with Black Panther commanding his forces to halt the invasion. Bucky Barnes a.k.a. the Winter Soldier, Black Widow, and Captain America are all there too (pointing to a post-credits scene from Captain America: Civil War where Cap drops Bucky off in Wakanda under Black Panther’s protection).

It ends referencing an Easter egg we saw in Guardians of the Galaxy Vol. 2, which hinted that Asgard and the Guardians inhabit the same cosmic universe, and Thor’s first meeting with The Guardians of the Galaxy.

Directed by the Russo brothers, Infinity War represents the culmination of a decade of Marvel moviemaking and the final piece in Marvel Studios’ cinematic plan to create a universe of interlocking, connected superhero movies. Various Marvel superheroes have already teamed up in crossover epics like The Avengers and Avengers: Age of Ultron. Infinity War looks to be the biggest and baddest of those crossovers yet.

Avengers: Infinity War (Part I) hits theaters on May 4, 2018.
