N'Jobu

N'Jobu is a posthumous antagonist in the 2018 superhero-film Black Panther. He is a former Prince of Wakanda who planned on selling vibrainium on the black market to ignite a global revolution. He is also the father of Erik Killmonger (the main antagonist of the film).

He was portrayed by Sterling K. Brown.

History
N'Jobu started off as the younger brother of T'Chaka as they both grew up to become legendary figures of Wakanda, with T'Chaka serving as its King while N'Jobu became an agent of Wakanda's intelligence force (known as War Dogs). As the days go by, N'Jobu met an American woman during a mission in California and fell in love with her, fathering their new child Erik and telling him about their origins in Wakanda.

However, N'Jobu grew disillusioned towards T'Chaka's isolationist policies, as he believes that they were doing more harm than good. Deciding that the only course of action was to initiate a global revolution, N'Jobu decided to betray his brother by revealing his country's existence to black-market arms dealer Ulysses Klaue and helped him infiltrate Wakanda in order to steal some vibranium. Unbeknownst to both N'Jobu and Klaue, T'Chaka had learned about his brother's treachery from his confidant Zuri, who previously disguised himself as an American citizen named James in order to gain the Prince's trust.

When Klaue's attack resulted in the deaths of several Wakandan citizens (including W'Kabi's parents), T'Chaka made his way to the United States and confronted his brother. During the encounter, N'Jobu learned about Zuri's true identity and tried to kill him, only for T'Chaka to force himself to kill N'Jobu in order to save Zuri's life before returning back to Wakanda. This event is what led a grieving Erik to vow revenge on Wakanda for abandoning him and causing his father's demise.
