The early footage shows Killmonger facing down T'Challa unmasked, but elsewhere he is also seen wearing a tribal mask. It's in that form that he is also seen planting explosives on the side of a wall, and EW reveals that he does so to break Klaue (Andy Serkis) out of CIA custody.
Klaue has a singular goal in mind, that being vibranium, a resource that Wakanda is rich with. The two will join forces against Black Panther and his council, but Killmonger wants significantly more than rare metals, and he will use Klaue to see that through.
Marvel Studios' "Black Panther" follows T'Challa who, after the death of his father, the King of Wakanda, returns home to the isolated, technologically advanced African nation to succeed to the throne and take his rightful place as king. But when a powerful old enemy reappears, T'Challa's mettle as king—and Black Panther—is tested when he is drawn into a formidable conflict that puts the fate of Wakanda and the entire world at risk. Faced with treachery and danger, the young king must rally his allies and release the full power of Black Panther to defeat his foes and secure the safety of his people and their way of life
