N'Jadaka's father was pressed into working for the villain Klaw. After Klaw fled the country N'Jadaka's family was exiled.
He ended up in Harlem, New York, where he developed a hatred of both Klaw and the Wakandan king. N'Jadaka changed his name to Erik Killmonger, and dedicated his life to avenging his father's death. He studied extensively at MIT.
He contacted T'Challa the Black Panther, who repatriated Killmonger to Wakanda. He feigned trying to make up with the king. Killmonger settled in a village that would later change its name to N'Jadaka Village in honor of him.
Killmonger dedicated his time to the overthrow of T'Challa's government, seeking to make himself ruler through various plots. Despite being defeated, and even killed, Killmonger would be resurrected by his followers and continue to plot.
He also raised a leopard named Preyy.
Killmonger was eventually able to defeat the Black Panther in ritual combat, gaining him chieftain status of the Panther clan. However, his body had a severe reaction to the heart-shaped herb all chieftains must eat as part of the ascension rite.
Killmonger remains on a life support machine while Wakandan scientists search for a cure.
Normal human male with intensive regular exercise. While on life support, Killmonger has below normal strength.
