Robert Morgan was the American student of an ancient Egyptian mystic called The Old Man of the Pyramids. He schooled Morgan in "all the ancient and modern sciences" and gave him the "Amulet of Annihilation, the weapon of the forces of right" which he tied around his right arm. The Amulet grants him powers including super-strength, super-speed, flight, the ability to generate electricity and radiate “lightning heat,” and a measure of invulnerability. His powers can be recharged by electricity.
