M’Baku is one of the greatest warriors of the African nation Wakanda, and a member of the outlawed White Gorilla. Challenging the T’Chaka, the ruling king of Wakanda, to a ritual trial by combat for the throne, M’Baku won through treachery, slaying the king.
As ruler of Wakanda, M’Baku moved swiftly to allow his allies Hydra and Ulysses Klaw to enter the country and begin to rob wakanda of its precious vibranium. He was eventually opposed by T’Chaka’s son T’challa, who had assumed the role of the Black Panther. The Panther defeated M’Baku, while his allies in The Avengers went on to thwart Hydra.
