Killmonger

Erik Stevens (born N'Jadaka) was a former American black-ops soldier of Wakandan origin through his father, Prince N'Jobu. His savagery while serving in the U.S. black-ops unit, earned him the nickname Killmonger. Years after T'Chaka had killed his father for betraying Wakanda, Killmonger then planned to forcibly dethrone T'Challa in order to accomplish his father's plan to seize control of the world using all of Wakanda's Vibranium technology and stop the oppression of people of African descent all across the world.

During his preparation to take the throne of Wakanda, he came across one of the worlds number one smuggler, Ulysses Klaue. He formed an alliance with him knowing his history, to someday use him for a greater plan.

During his work with Klaue, he worked with two other people and people named them the Frightful Four! To learn more about this read The Fight of Fours.

He killed Ulysses Klaue to gain access to their city, Killmonger seemingly killed T'Challa during their ritual combat and took the throne. Just before Killmonger unleashed his plans, the Black Panther returned and challenged Killmonger, eventually defeating and killing him during their final battle.
