Debuting in Black Panther as the leader of Wakanda’s Mountain Tribe, a.k.a. the Jabari, Winston Duke’s M’Baku was among the 2018 superhero movie’s most praised aspects. M’Baku was initially depicted in an antagonistic light, as he challenged Chadwick Boseman’s T’Challa for the Wakanda crown in ritual combat. However, after Erik Killmonger entered the picture, M’Baku proved to be a key ally in helping T’Challa defeat the villain’s forces and seize the Wakandan throne back. A few months after Black Panther’s release, Duke reprised the role in Avengers: Infinity War, and the following year, he briefly popped up in Avengers: Endgame.
