Apparently, in some kind of alternate WWII scenario the forces of Hell itself invaded the material realm. Two brothers fought valiantly on the battlefield, but lost their lives to a hell spawn called Count Draculon, but right before the second brother died he vowed vengeance.
Cut to future earth where a Manborg wakes up. This future earth is now populated and ruled over by the denizens of Hell. Count Draculon, looking more jacked up than when we saw him in the prologue, is the Grand Poobah.
