The fictional character N'Jadaka, AKA Erik Killmonger, of Marvel's Black Panther comic book series earns a PhD in Engineering and an MBA from MIT, where he eventually teaches. He makes his first appearance in "Panther's Rage," Black Panther, Vol. 2 No. 6 (September 1973).
T'Challa returns to Wakanda to find his homeland threatened by Erik Killmonger. Killmonger had been ravaging villages to attract the Black Panther's attention. When confronted by T'Challa, Killmonger dismisses the African Prince, having T'Challa fight with his leopard "Preyy". When T'Challa stops the leopard by apparently snapping its jaw, Killmonger finishes off a fatigued T'Challa and throws him over a waterfall.
