Warning: If you haven’t seen any of the Marvel movies from last year or earlier this year, you will be spoiled.
Team Captain America
Captain America Civil War’s plot hasn’t been fully revealed yet, but what we do know so far is that superheroes haven’t been making friends over the past few months. A Hulkbuster fight in South Africa already pissed people off, but the Avengers destroying a city into pieces? Yeah, that can’t be good PR that anyone can come back from.
All we know right now thanks to Ant-Man is that superheroes apparently have restrictions applied to them thanks to something known only as “The Sokovia Accords,” which probably means that heroes aren’t allowed to do their thing unless they conform to a specific set of rules (but not giving up your identity, secrets don’t exist in the MCU). Cap’s team is definitely not in love with this idea, and his side includes…
Bucky Barnes was Steve Rogers’ lifelong friend from before Steve took the serum that turned him into Captain America. Barnes was part of Cap’s Howling Commando unit in WWII, serving as a sniper during missions. During the war, he was captured by Hydra and brainwashed into becoming the Winter Soldier, gaining a cybernetic arm and deployed to perform world changing acts of terrorism over the next several decades.
At the end of his titular film, Barnes vanished and tried to piece together his old life, but as the trailer shows us, that isn’t going as planned. In any case, Civil War will partially involve the government wanting Barnes to answer for his crimes, and possibly being executed for them. Since he’s literally the only thing from Steve’s life that remains from the old days, Steve’s doing everything in his power to protect him, and that includes going against the government and fighting fellow Avengers.
A fellow war veteran turned VA, Sam Wilson was given cybernetic wings during his stint as a soldier. He first meets Steve while jogging in DC, and after Steve and Black Widow are framed by the Hydra-infiltrated SHIELD, Sam helps them bring both organizations down. Sam later shows up in Avengers: Age of Ultron as a member of the New Avengers and fights Ant-Man (and loses) in the latter’s movie.
Sam’s a goodhearted person who instantly connects with Steve when they both meet, and that’s why Steve went to him while on the run. Sam’s more of a soldier than a spy, and to him, there’s no better honor than having Captain America come to you for help. He knows that going up against the government yet again will lead to him getting shot at, but it won’t stop him from joining Cap’s side again.
First making her appearance in Age of Ultron from earlier this year, Wanda Maximoff is a war orphan with a huge grudge against Stark. Her and her brother, Pietro, joined up with the homicidal AI Ultron, then later defected to the Avengers when they learned that he was much worse than the guy who created him. Even though her brother died during the final battle, she stayed with the New Avengers to master her powers of telekinesis and mind control.
Odds are that Wanda is on Cap’s side because she sees a bit of her and her brother in Steve and Bucky. While not entirely similar, Bucky is the only thing Steve has left in the world, much like Pietro was for her. She also knows what it’s like to be manipulated by Hydra and turned into something you didn’t want. Plus, she still probably hates Stark for all that destruction he caused to her home.
Clint Barton is Black Widow’s partner in crime, favoring a bow and arrow over guns. He’s mainly been more of a supporting Avenger, calling out shots and providing opportunities for the much stronger members to attack. After Age of Ultron, he retired from the superhero game to be with his wife and family. Which is why his appearance in Civil War is all the more surprising.
It’s possible that he’s brought back into the fold by choice, since this is a definitely bad situation for all involved. He could even probably be Bucky’s “bodyguard” from afar, given his enhanced vision. His role in all of this is unclear at the moment, but one thing’s for certain: Ant-Man will also be in this, which means they have to perform the greatest superhero combo of all time.
