Tomb of Dommash

Dommash was an ancient demon lord, who was the first alien threat to humanity. His powers consisted of draining life energies away from humans, leaving them bone dry and stopping their blood-flow in seconds. No technology at the time was sufficient to kill him, but eventually when near his complete triumph, after having turned three big cities in ruins, he found out that he's not immune to bacteria on Earth, which eventually rendered him very, very vulnerable and the humans finished him.
His corpse was buried and locked away for good in the "Tomb of Dommash". More than two centuries later, a Japanese warrior, desperate for help against invading aliens, Takeshi Sawada dared to enter the Tomb and infuse with Dommash's remains, making him half-human, half-demon.
