Ultimately, Cap and Tony engage in an Avengers civil war, with old friends taking sides, and new allies - like Ant Man ( Paul Rudd) and (possible spoiler alert!) Spider-Man ( Tom Holland) - joining the fray. Unwilling to turn Bucky over to be arrested without learning more about what happened, Cap enlists his side to go against the accords and protect Bucky. One of the casualties was the King of Wakanda his son, Prince T'Challa ( Chadwick Boseman), believes it's his duty to seek vengeance and emerges as the Black Panther. When an assassin detonates a bomb at the United Nations, where the accords were to be signed, the culprit seems to be Bucky Barnes/the Winter Soldier ( Sebastian Stan) - Cap's dear old friend. Tony thinks it's the right thing to do, as do Rhodey and Vision, but Cap disagrees. Back home, Tony Stark/Iron Man ( Robert Downey Jr.) calls upon Cap, Natasha/Black Widow ( Scarlett Johansson), Rhodes ( Don Cheadle), Sam/Falcon ( Anthony Mackie), Vision ( Paul Bettany), and Wanda/Scarlet Witch ( Elizabeth Olsen) to sign an international accord that would limit the Avengers' authority and allow them only to act at the behest of the Secretary of State and a global task force. CAPTAIN AMERICA: CIVIL WAR opens with a fight between a crew of Avengers led by Steve Rogers - aka Captain America ( Chris Evans) - and heavily armed mercenaries in Lagos, Nigeria, that ends up causing unexpected civilian deaths.
