It's all about team-ups in the new Avengers: Infinity War trailer.
In the clip, viewers get to see their favorite heroes onscreen together as Gamora explains all she knows about her father, Thanos, to Tony Stark, Captain America arrives in Wakanda to greet T'Challa, and Star-Lord tells Iron Man his plan "sucks" in front of Spider-Man and Drax.
There's also a hilarious meeting between Spidey and Dr. Strange as the Sorcerer Supreme introduces himself. But Peter thinks "Strange" is a "made-up name" so he re-introduces himself as Spider-Man instead of Peter Parker.
But the most epic scene comes when Cap holds off Thanos' Infinity Gauntlet–covered fist.
This is also the first trailer to be released since Marvel moved the release date up a week. Avengers: Infinity War was originally supposed to be released in May, but Robert Downey Jr. aka Tony Stark pulled some strings and now it'll be released on April 27.
