The young actor who portrays Toussaint in Wakanda Forever is none other than Divine Love Konadu-Sun. According to his official IMDb page, the Marvel project marks his acting debut. However, there's no doubt that he will pop up on the big screen again, either in other productions or reprising his role as Prince T'Challa II in the near future.
If we had to guess, Divine could reprise his role in a Young Avengers project. However, there's the possibility that the MCU will recast the character with a more well-known actor as they did with Cassie Lang in Ant-Man and the Wasp: Quantumania (let's hope that's not the case).
Besides that production, we could see Divine appearing in a third Black Panther film — maybe he will head to Wakanda, assume the throne as the rightful heir, and protect the nation as the next full-fledged version of Black Panther.
Black Panther: Wakanda Forever is now in theaters.
