Klaw was hired by
N'Jobu to steal
Vibranium from the
Mena Ngai, in order to distribute it among the oppressed.
Klaw succeeded in stealing a quarter of a tonne of vibranium, detonating a bomb when the
Border Tribe tried to stop him taking it out of the country, killing several members of the tribe, including
W'Kabi's parents.
As N'Jobu was killed by
T'Chaka for his role in the theft, Klaue kept the vibranium for himself, selling it off in small amounts on the black market via his associate
Andreas de Ruyter in order to hide his role in the sales.
