Context
N'Jadaka, also known as Erik Stevens, was a former American Navy SEAL of Wakandan descent through his father, Prince N'Jobu. N'Jdaka's savagery during his service in the U.S. Special Operations earned him the nickname Killmonger. When Killmonger was a child, T'Chaka killed his father for trying to kill Zuri, who had denounced him for betraying Wakanda. This event led Killmonger to dedicate his entire life to dethroning his cousin, T'Challa, in order to finally accomplish his father's goals of taking over the world by using all of Wakanda's vibranium technology to end the oppression of the descendants of African peoples throughout the world. Manipulating and killing Ulysses Klaue to gain access to the kingdom, Killmonger appeared to kill T'Challa in a ritualistic battle and reclaimed the throne. Just before Killmonger could unleash his forces across the world, Black Panther returned and challenged Killmonger, neutralizing and killing him in their final battle.
