Origin:
Once a powerful ruler in ancient times, Mortus Rex's thirst for immortality led him down a dark and forbidden path. Seeking eternal life, he delved into forbidden rituals and made a pact with dark entities. However, his quest for immortality came at a terrible price. The ritual turned him into an undead being, forever trapped between life and death.

Bound by an unholy curse, Mortus Rex became an immortal embodiment of death itself. His soul forever tormented, he was condemned to walk the earth as an eternal specter, driven by an insatiable hunger for power and vengeance.

Throughout the centuries, Mortus Rex honed his dark powers, amassing knowledge of forbidden magic and necromancy. He discovered how to control and manipulate the forces of death, using them to his advantage. His reign of terror and quest for ultimate power continues unabated, as he seeks to dominate the world and extinguish all light in his relentless pursuit of absolute control.

His undead and immortal nature, coupled with his mastery over necromantic arts, has made Mortus Rex a fearsome supervillain. With each passing era, he becomes more powerful, relentless, and determined, a harbinger of death and despair to all who stand in his way.
