Powers: Nephrus is skilled in the art of mummification. He uses a variety of herbs and chemicals, able to cause paralysis and other conditions. He also apparently had certain precognitive powers.
In the modern era, he possesses the ability to manipulate the forces of magic to a great degree, projecting energy bolts, levitating, animating inanimate matter, etc. However, he requires the Gem of Nephrus to maintain his existence on the Earthly plane.
