Avengers: Infinity War - Every Character Confirmed So Far

Confirmed By: Again, his contract, though the Russos have mentioned both Cap and Iron Man being crucial to the plot of Infinity War. So that, as well.

Plot Predictions: After protecting Bucky but then being released by Tony Stark at the end of Civil War, Steve Rogers probably doesn't know where he stands with Stark, and as their relationship is described as "central", we can probably all expect it to go through a lot on the road to resolution.

Depending on how Black Panther goes, Cap also has Bucky's assumed guilt to deal with and his own issues of identity, after he cast off Captain America's shield and name. Will we see him as Nomad in the run u to Thanos' big moment?
