In the first , several characters aren't seen... Spider-Man, Ant-Man, and the Vision are all missing in action.
However, one character, a villain in this case, managed to slip by without being noticed for a little while. But we got him!
Frank Grillo's Crossbones can be seen in the Captain America: Civil War trailer, presumably in pursuit of Bucky (at least, the trailer makes it seem that way).
Frank Grillo first appeared as Brock Rumlow in the Marvel Cinematic Universe in 2014's Captain America: The Winter Soldier. His character was left badly burned and some presumed him dead but his character is returning with a vengeance, come Civil War.
What Easter Eggs or characters did you catch in the Civil War trailer?
