Ok so this is going to be a villains battle. This is Negan and the Saviors at full power at their introduction. Facing off against them is the Night King and the Army of Dead, bringing the winter and long night with him. This is on Negan's territory. Fight to the death and last man standing. Just to be clear either Negan and all the Saviors have to be dead or the Night King and the Army of Dead do. Who wins and why?
