Disgaea 5: Alliance of Vengeance has a group of characters that come from different Netherworlds. Usalia, for example, hails from a Rabbit Netherworld while Red Magnus is from the Burning Netherworld.
Like Killia he’s out to get Void Dark, but his reason isn’t personal like the protagonist’s. Red Magnus simply wants to be the most powerful overlord. He looks plenty powerful already since one of his attacks crushes an entire planet. Hmm… considering that I wonder how powerful Void Dark really is. Japan will find out on March 26 when Disgaea 5 comes out for PlayStation 4.
