Dispator

Balor, the 49th demon lord.

Formerly known as Dispater, god of the underworld and firstborn of Vir and Iwaiden, who are the sole spawn of Oridei. He is the eldest of three children, himself, Dea Matrona, and Itol. Originally, Dispater ruled over the empty land of Tartaros, but he envied how much fun all of his brethren were having. Eventually, it got to the point where even lesser gods and beings looked down on him and thought themselves better than him. This angered him immensely, as his firstborn status was not being upheld. Eventually he had had enough and turned to the demon side, obliterating the previous demon king with his immense power. After being crowned 49th demon king, he instituted massive reforms that strengthened the demon forces. After his forces were of a reasonable size, he launched a siege on Asgarde, intending to make them all pay. After his eventual retreat, he now resides in his throne room, recharging his power.
