Before unwittingly encountering the mystical Crimson Gem of Cyttorak, Cain Marko was a normal man, but he was a man consumed by jealousy of his half-brother Charles Xavier. Cyttorak seized on that jealousy, turning Marko into a being of untold power - an unstoppable force of destruction that would plague Xavier and the world for decades to come.
