On the front of the boxes for the two new LEGO sets inspired by Black Panther: Wakanda Forever, artwork replicating the cast of the film can be found, with the same images transformed into minifigures on the back. However, there are a couple of familiar faces in these renders that don’t have minifigures.
Both Okoye and M’Baku appear on the back of the box for 76211 Shuri’s Sunbird and 76213 King Namor’s Throne Room, though there are no physical minifigures for either of these characters in the Black Panther: Wakanda Forever models revealed so far.
This could suggest that these two minifigures will appear in a future LEGO Marvel Black Panther: Wakanda Forever build, though that’s only speculation based on these existing designs and it has not been officially confirmed.
Notably, Okoye has had a minifigure before in 76099 Rhino Face-Off by the Mine, but the design featured on the back of the box features additional printing on the head, suggesting that this could be an all-new version of the character.
Meanwhile, M’Baku has yet to receive a minifigure, meaning this is an entirely new design that, at the time of writing, only exists on the box art. It seems unlikely that a brand new minifigure has been designed just to be on a box but no further sets based on Black Panther: Wakanda Forever have been confirmed by the LEGO Group at this time.
