Avengers: Infinity War Trailer Breakdown - 31 Images You Need To See

6. Thanos Vs. Iron Man

The trailer provides a quick glimpse of one of the most-anticipated match-ups of Infinity War: Iron Man facing off against Thanos.

Presumably after seeing Spider-Man get beat to a pulp, Tony Stark enlists the help of his new Stark Suit (which looks incredibly swish, by the way), though it doesn't seem to be much help, as Thanos smashes him in the face with a powerful punch while wearing the Infinity Gauntlet.

Iron Man isn't just knocked to the ground, though: he hits the floor like a sack of you-know-what and goes totally limp, perhaps suggesting that Stark actually loses consciousness after the hit. It would be one hell of a way to cement that Thanos is so much more powerful than anything The Avengers have ever faced before.

5. Bucky Is Thawed

One of the more interesting surprises in the trailer was the presence of Bucky, who has apparently been thawed out since going into deep freeze at the end of Captain America: Civil War. He's seen readying a machine gun alongside Cap and T'Challa's army as they face off against the Outriders.

This raises a few questions: is Bucky thawed out because a cure has been found for his brainwashing, or because Wakanda desperately needs every soldier it can spare? And is he revived during the Black Panther solo movie, or does he stay frozen until Infinity War?

Either way, it's great to see the Greatest Love Story of Our Time, Bucky and Steve (aka Stucky), blissfully continue.
