True to its billing as the biggest Marvel movie ever, Avengers: Infinity War looks to be assembling just about every surviving Marvel Cinematic Universe character for the all-out war with Thanos (Josh Brolin) over control of the Infinity Stones and the future of the MCU. The newest TV spot for the film features yet another beloved supporting character who we now know will pop up for at least some of the film: M’Baku (Winston Duke), one of the standout Wakandans featured in Black Panther.

M’Baku’s involvement make sense. At least one huge action setpiece in the film takes place in Wakanda, and we already knew that T’Challa (Chadwick Boseman) would be joined in the film by his allies Shuri (Letitia Wright) and Okoye (Danai Gurira). It only stands to reason M’Baku would show up as well. Plus, Black Panther is literally the biggest hit Marvel has ever had in the U.S. Leaving out beloved characters from the film would not be a good move.

Here’s Infinity War’s official synopsis:
