Sebastian Stan's Bucky Barnes Fights Chadwick Boseman/Black Panther In Captain America 3 Clip

It's the Avengers versus the Winter Soldier in an action-packed clip from Captain America: Civil War! Although the sneak peek was already previewed on Jimmy Kimmel Live, an extended teaser reveals that Sebastian Stan's Bucky Barnes actually faces off against Chadwick Boseman's Black Panther after defeating Iron Man and Black Widow!

The new Civil War clip opens with Tony Stark (Robert Downey Jr.) sneaking up on Bucky as he takes on a group. Natasha Romanoff (Scarlett Johansson) advises Tony that his team is already "in position," and he moves in to blast Bucky. Unfortunately, it doesn't work as planned and Tony ends up almost being shot by the Winter Soldier!

Luckily, the team moves in to save Tony. Sharon Carter (Emily VanCamp) attacks but is quickly taken down before Black Widow tackles Bucky, who doesn't have any trouble pinning her down. Natasha tries a different approach, pleading with the assassin and asking if he could recognize her. It doesn't work, as Bucky continues choking her.

Suddenly, T'Challa pounces on Bucky, who immediately shakes him off. Although the Winter Soldier tries to escape, Black Panther isn't quite ready to give up the fight. T'Challa leaps up to face Bucky before the scene fades off.

What could probably happen when Black Panther takes on the Winter Soldier? It has previously been rumored that the Soviet assassin is responsible for the death of the King of Wakanda, and T'Challa might be out for revenge. Will T'Challa defeat Bucky? The truth will be revealed when Civil War finally hits theaters this May.
