Hawkeye: The Hawkeye/Black Widow split here is intriguing, leading us to think there may be a falling out between the two long-time friends (Hawkeye even named his daughter after Natasha). As it is, he lands firmly on the Cap side of the equation for Civil War.
Sharon Carter: The daughter of Peggy Carter, Sharon first appeared in Captain America: The Winter Soldier in a small supporting role as Cap’s secret bodyguard. Looks like she’ll take after her mom and support Steve Rogers in this battle.
Falcon: Falcon and Cap have already been fighting alongside each other for awhile now, and in a lot of ways he’s Steve’s closest friend and ally. He’ll also come in handy as the only member of team who can fly, running up against the far more advanced Iron Man suit.
Bucky Barnes: When last we saw Bucky, Cap and Falcon had trapped his arm in a vice in the end credits stinger following Ant-Man. Now, he’ll fight on the side of his childhood buddy, hopefully a shade less brainwashed now.
Ant-Man: In addition to appearing above, you can see Scott Lang perched on Captain America’s shoulder in another over here. Lang went to prison as a social justice warrior, so you can bet he’ll be ready to take on the U.S. government when called upon.
