MORDO

Baron Karl Amadeus Mordo is a powerful dark sorcerer created by Stan Lee and Steve Ditko for Marvel Comics. First appearing in Strange Tales #111 in 1963, Mordo trained under the Ancient One alongside Stephen Strange before becoming Doctor Strange's arch-nemesis. Driven by an unyielding desire for supreme mystical power, Mordo frequently strikes dangerous bargains with dark extra-dimensional entities like Dormammu.
