Lucifer

This ancient, vampiric demon resides in a castle in the Devil's Hand mountains, plotting to plunge the world into eternal darkness and rule it with monsters. He commands a loyal army of undead, including a powerful crimson demon and a servant, and possesses the immensely powerful Sleeping Princess jewel. Possessing two distinct appearances, he can shift from handsome to menacing, wielding energy blasts and possessing immense power. His ultimate goal involves using the jewel's energy to power a device capable of destroying the sun, a plan that culminates in a dramatic confrontation.
