Duel in the Great Mound

"I'mma track down anyone who would even think of being loyal to you! And I'ma put their ass in the dirt, right next to Zuri!"

- Black Panther and Erik Killmonger

The Duel in the Great Mound was a open confrontation between Black Panther and Erik Killmonger.

Background
Erik Killmonger, now the king of Wakanda and supported by W'Kabi and his army, prepared shipments of Wakandan weapons to be distributed to operatives around the world, so they may spread it to other people of African descent so that they may fight back against their oppressors.

Overseeing the ships leaving Wakanda, he sees one of them shot down by T'Challa, making his return as Black Panther. Killmonger orders W'Kabi and his army against T'Challa, but he blasts them away with his kinetic energy. Enraged at Killmonger's evil nature, Okoye and a few of her warriors got ready to attack Killmonger, who reveals he has taken one of the upgraded Habits for his own use. During the fight, Nakia and Shuri join Okoye as they fight Killmonger. With M'Baku and the Jabari Tribe arriving to help the fight, T'Challa focuses his attention on Killmonger, who is about to hurt Shuri.

Duel
T'Challa tackles Killmonger and they fall down into the vibranium mines. There, they continue their fight, evenly matched, until T'Challa has Shuri utilize the mag-lev train's sonic stabilizers to disrupt the vibranium technology in his and Killmonger's suits, leaving him exposed so that T'Challa may impale him with his own short spear.

Aftermath
"Just bury me in the ocean with my ancestors who jumped from ships, cause they knew death was better than bondage."

T'Challa sat down next to Killmonger, who complimented him on the move. He explained that his father stated that Wakanda was the most beautiful place on Earth. Saddened, T'Challa drags Killmonger outside the Great Mound to watch the sunset. T'Challa told Killmonger that Shuri could heal the wound that he inflicted on him. Killmonger declines the offer asking to be buried at sea like his ancestors, stating that when they were brought over to America on boats, some of them jumped out and drowned in the sea, as they knew it was better to die that way than it was to be imprisoned. Killmonger decided to remove the spearhead from his body, and died peacefully.
