Your correct OP
Marvel doesn't like Tchalla which should be obvious by now, dude gets push to the side in his intro, in the book, the movie, and the tv/web show. They want black panther to be a feminism thing which was also obvious, Tchalla is the only normal black male with no agendas in the entire Black Panther franchise(mbaku is the big scary black man stereotype).
Remove Tchalla and everyone else is a black women. The only other black male is biracial with a white dad which destroys the whole concept of black panther...lets find a way to force a white man in the all black nation
Okoye is redundant as Tchalla can already fight, She is there to reduce Tchalla's image as a fighter - (Storm could have her spot)
Shuri is redundant as Tchalla was already a genius, She is there to reduce Tchalla's intelligence - (Nakia could have her spot)
What is left for Tchalla?
They were both created to stealth nerf T'challa
Nakia is good and so is Storm. Nakia and Storm as a team works as well.
Okoye + Shuri is just Tchalla...

nikka Nerds still ain't figure that out
What your dealing with above is simple c00n behavior. These nikkas get one black hero movie and act like that's it we don't need no more black male hero's we want villains..... There are zero black female villains though Amanda Waller is not a villain.
The majority of black male characters are already villains(that's the joke)....the others are side kicks. They just not in super hero movies.
They only want to see Black men as toxic people. Complain about black male toxicity yet that's the only black male they create
These are the nikkas that fukked up black communities by corrupting the minds of black children who would later grew up to terrorize the neighborhood.
