When it comes to dues ex machina ass pulls, Hickman's "I create ships to survive the end of all existence" T'Challa is matched/surpassed only by Aaron's "I just pull anti-anything tech out my ass, because I'm the Black Panther" T'Challa
So yea, we already know villains have firearms with ammunition that suppress the mutant gene via nanites. So T'Challa and anti-mutant pulse bomb nanite fukkery is the type of fukkery I'd expect from Hickman; it would be a cold war.
Or, Gentle is repurposed from being a p*ssy to being the ultimate double agent spying for Wakanda while playing the role of a p*ssy this entire time
After goldballs, anything is possible
BP did make a temp mutant gene suppressor out of radio shack parts when he was depowered and doing the hells kitchen thing. Who knows what he could create with his full resources
