A book with black characters I'd get
Storm
Windshear
Bishop
Jesse Bedlam
Tyke Alikar-The Anarchist
Frenzy
some of those characters are dead or depowered (Windshear is depowered and also has leukemia). this would imply healings-resurrections-repowerings
I am Latin American and I don't like the idea of a book with only black characters just because btw. There has to be a reason apart from their race for that specific team to exist. Otherwise it sounds like they met in some private club only for black people.
