The latest Avengers: Endgame Special Look trailer is full of tantalizing new secrets, but one thing that stuck out is how much it featured Tony Stark. Whereas the first trailer made it seem like he might not even make it back to Earth, this one shows he not only survives but reunites with Pepper Potts, makes up with Captain America, and built a new suit of Iron Man armor.
But that’s not just any Iron Man suit. It’s a very specific look for Iron Man from the comics, and it actually tells us a great deal about what might be going on with Tony in Endgame.
