Black Panther... Significant Other/Love Interest... Rogues Gallery... Wakanda... Period!
Trying to sell something else is futile unless you want to commission his own office like the other A-list super heroes have and equip it with it's own editorial staff answering only to this franchise!
If Hickman with all his "Slow Burn" 28 issue build up can't find time to develop such a large ensemble cast then who can or even has the time to do so?
New York is the base of operations for most of the main Marvel heavy hitters but there is no attempt to define very single cab driver or hot dog vendor just to flesh out nameless meaningless characters so why should Wakanda be any different?
Hey who is the traffic cop that directs traffic after the Hulk smashes three city blocks worth of property... Nobody who writes or reads comic books cares so keep it moving with the most essential solo characters only!
It's 23 pages of illustrated panels wasted trying to tell stories that 60,000 down to 20,000 hemorrhaging readers are not supporting because they really only want to pay for T'challa as king!
No matter what direction the writer goes some fans are going to be upset that the focus was pulled from who they favor for the other character whom they do not favor... Even if one of the two was off panel at Disneyland there would still be the question what that other character thinks or does just for the sake that they are part of the franchise!
It's time to go from "I wonder what Shuri is doing" to "what the heck was Princess Zonda doing taking over Wakanda" and "will Malice turn the Doras against him" which makes for way more interesting stories and builds that lagging rogues galleries!
Andy Serkis is Klaw and Barked Abdi is waiting by the phone for Disney to make that call for him to play Achebe and then come over here and take my money please!

I don't care about the Barbie Doll ensemble casts with Ken and them I demand that the villains of Black Panther be fleshed out and he stops borrowing other character's rogues and grows up like other franchises have and pays his own bills beyond the piggyback level!
I don't play with my toys in the sandbox with anything other than heroes, villains and damsels in distress... Aint much I can do do with moms, siblings, distant cousins and uncles that do not want to get their diabolical Lion King Uncle Scar on and stab their nephews in the back!
