Other recent arrivals include Diplo and "The Four" alum Zhavia, who appears on "Welcome to the Party" from "Deadpool 2" alongside Diplo, French Montana and Lil Pump.
For those unfamiliar, Leitch is a director that is probably best known for movies such as the original John Wick and also Deadpool 2, so suffice to say that he knows a thing or two about shooting fight sequences.
T'Challa, king of Wakanda, will join previously announced heroes Captain Marvel, The Hulk, Rocket Raccoon, Deadpool, Black Bolt, Crystal, Ronan the Accuser, Loki, and Thor.
