The Captain America: Civil War synopsis, teases “another international incident involving the Avengers” that “results in collateral damage.” The vague description could lend itself to an event that involves Wakanda but according to HH, there might be another way T’Challa a.k.a. Black Panther gets involved. They claim that T’Challa is actively hunting down Bucky Barnes a.k.a. The Winter Soldier.

 

Black Panther's home country of Wakanda was teased in Avengers: Age of Ultron and with Black Panther's inclusion in Civil War it is possible that the Panther could fall on the side of Tony Stark on the pro 'Superhuman Registration Act'. Coupled with the fact that he is hunting Bucky Barnes we could see Black Panther face off against Captain America. We know that Black Panther's costume has elements of Vibranium (the same metal used in Cap's shield) which should make for a spectacular showdown between the two.

 

It's a pretty safe bet to imagine that The Winter Soldier assassinated someone close to T'Challa while working for Hydra which would explain the Black Panther's pursuit for Bucky. Another teaser in Age of Ultron was joked by Anthony Mackie's Sam Wilson / Falcon "I was enjoying working on a missing person's case". The easter egg leads us think that Cap & Falcon will bump heads with Black Panther in the pursuit of Bucky Barnes.
