The Black Panther is just like any other Royal Family. So since Chadwick Boseman is dead with cancer, We could make The Black Panthers sister the new generation of Wakanda history/present/future because why would we not? Just wondering, Would there be anyone willing to challenge her and if yes, Would they even stand a chance?
Remember how James Rhodes aka WAR Machine was replaced?
How about Edward Norton as the Hulk for the rufulo who?
We even had 3 Spidermen.
Character can be replaced because they were already replaced in the MCU. Shuri would just cause people to lose interest. They will probably Do A CGI Leah and have black panther replaced.
Then again I don't know because this phase is looking pretty lame. Female Thor and Shang Chi?
