Marvel unveiled the second trailer for The Avengers Wednesday, derailing all activity in the Comic Vault offices with a single, collective nerdgasm.

The trailer still doesn’t reveal the identity of Loki’s mystery army, but we (and by “we,” I mean “I”) are still holding out hope that it’s the Skrulls.  Regardless, the trailer does tease some sort of fight between Captain America, Thor, and Iron Man, which undoubtedly ends with them being superhero bros.

Needless to say, this movie looks more and more amazing with each new trailer.  The Avengers opens May 4, 2012 and you can check out the second trailer below:
