Rama-Tut

Rama-Tut was a Pharaoh in Ancient Egypt and the original owner of the Eye of Ages. He ordered the death of En Sabah Nur that led to his five-thousand-year sleep, but not before becoming Apocalypse.

According to what was translated by Beast in Dark Horizon II, it is suspected that Rama-Tut was a man from the future and had traveled to the past, bringing with him advanced technology. When Apocalypse came after him, he fled, but he left his technology behind, which Apocalypse took as his own for his own purposes.
