Earlier today, Jimmy Kimmel announced that Chris Evans (Captain America) and Robert Downey Jr. (Iron Man) will be appearing on tonight's episode of Jimmy Kimmel Live!, with a "big surprise" from Captain America: Civil War. As many assumed, the first trailer was unveiled on the late night show tonight, along with the first poster. If you look closely in some of the action-packed fight scenes, you'll also get the first official glimpse of Chadwick Boseman's Black Panther, who is seen battling with both Cap and The Winter Soldier.

During Marvel's massive press event last October, Black Panther was announced as one of the studio's Phase Three projects, with Chadwick Boseman introduced as T'challa. It was also confirmed that, along with his stand alone adventure Black Panther movie, which hits theaters on February 16, 2018, T'challa will first be seen in Captain America: Civil War. While we didn't know at the time which side Black Panther would be fighting for, promo art revealed in August confirmed that T'challa will be fighting alongside Tony Stark (Robert Downey Jr.).

Iron Man's team also includes War Machine (Don Cheadle), Vision (Paul Bettany) and Black Widow (Scarlett Johansson), while Team Cap includes Bucky Barnes/The Winter Soldier (Sebastian Stan), Ant-Man (Paul Rudd), The Falcon (Anthony Mackie) and Sharon Carter, a.k.a. Agent 13 (Emily VanCamp). What isn't clear at this time is which side Scarlet Witch (Elizabeth Olsen) and Spider-Man (Tom Holland) will end up on. Captain America: Civil War picks up where Avengers: Age of Ultron left off, as Steve Rogers leads the new team of Avengers in their continued efforts to safeguard humanity. After another international incident involving the Avengers results in collateral damage, political pressure mounts to install a system of accountability and a governing body to determine when to enlist the services of the team. The new status quo fractures the Avengers while they try to protect the world from a new and nefarious villain.
