Black Panther Vs Ka-zar: War
In a battle for total control of all (and all types) of vibranium, Wakanda invades the Savage Land.
Would this break down into a Vietnam type scenario? Panther is the invading force, and has tech and even magic to an extent. Ka-Zar can rally various tribes, has tech and magic resources and dinosaurs to use in offensive tactics.
Both have ties to the super human community, most notably the X Men.
SHIELD would have a vested interest in the outcome, but who would they back and why?
In this scenario, all vibranium is whole and not in its current state in the MU proper...
