Master Khan, an evil sorcerer of K’un-L’un, first appeared in Strange Tales #77 (May 31, 1960).
Khan was once a man, a youthful occult scholar who sought only to love his wife and children. The king of the Middle Eastern nation Halwan recognized Khan’s power and sought to claimed it. When Khan refused, the king took his family hostage, torturing and slaying Khan’s youngest daughter on the rack. Though much of Khan’s history is unrevealed, he has stated that all the good in him died with his daughter.
