Egyptian Era Elemental Enigmas: Metamorpho and the Two Princes

Ancient Egypt had connections to the 20th century on the parallel planes of existence of Earth- One and Earth-Two. These were primarily through Justice Leaguer honorary member Metamorpho and Justice Society founding member Hawkman, as well as through a pair of Egyptian princes in Raman and Khufu.

Metamorpho himself journeyed back to ancient Egypt alongside his allies of the Outsiders, due to the machinations of Hath-Set's doppelgänger... high priest Ahk-Ton. He sought to have Rex Mason aka Metamorpho as his subservient agent. This had been Ahk-Ton's original intent, as it would take thousands of years before the Orb of Ra could create the perfect pawn in Mason to be transformed into the Elemental Man.

Around that same era, both Earths had benevolent rulers in Prince Raman of Earth-One and Prince Khufu of Earth-Two, Prince Khufu reigned. While Raman possessed mind-over-mind abilities allowing him to move objects with his mind, Khufu discovered Nth metal which allowed him to levitated objects defying gravity. Thousands of years later, these men's minds merged with 20th century heroes Mark Merlin of Earth-One and Carter "Hawkman" Hall of Earth-Two (their counterparts Mark King and Katar "Hawkman" Hol had different origins and familial connections).
