Black Panther (2018)

Killmonger, as the reigning king of Wakanda, orders the nation's supply of vibranium weaponry to be flown out to Wakandan spies across the world to overthrow national governments. T'Challa, having recovered from his duel with Erik earlier, returns to the outskirts of the Wakandan Design Group on Mount Bashenga to reclaim the throne.

W'Kabi and the Border Tribe, who have sided with Killmonger in his pursuit of a Wakandan empire, are dispatched in order to stop T'Challa, but Okoye realizes Erik is too hateful to be a just king, and she and the rest of the Dora Milaje turn against him and the Border Tribe; Nakia and Shuri aid them in the fight. Meanwhile, in Shuri's lab, Ross remote controls a jet to destroy the vessels carrying the vibranium weapons.

Okoye and the Dora Milaje become outnumbered by the Border Tribe and their armored rhinos, but M'Baku and the rest of the Jabari provide reinforcements to turn the tide of battle. When T'Challa notices Killmonger aiming to kill Shuri, he tackles Erik into the Great Mound. On the surface, W'Kabi and the Border Tribe surrender to Okoye.

Killmonger and T'Challa fight on the railway containing the trains that escort vibranium from the Great Mound to Wakanda. The technology that temporarily sterilizes the vibranium has the same effect on both men's Black Panther suits, which T'Challa exploits by stabbing Killmonger with his own iklwa while the suit is unstable.

T'Challa helps Erik up and the pair view the Wakandan sunset. T'Challa offers to get Erik medical attention the injury, but Erik refuses, assuming T'Challa would imprison him afterwards. Wanting to die a free man like Africans who escaped the fate of slavery by committing suicide, he pulls the weapon out and bleeds to death.

W'Kabi is removed from the Wakandan council and M'Baku joins in his place. T'Challa and Shuri travel to Killmonger's childhood home in Oakland, the first site of Wakanda opening itself up to the rest of the world.

In a scene during the credits, T'Challa reveals the truth about Wakanda in a United Nations press conference. In a scene set after the credits, Bucky Barnes awakens from his cryogenic sleep, where he is greeted by Shuri.
