Over 11,000 years ago, Nommo, the wizard-king of the African nation Kor, stood in the rolling pillar of life which gave him incredible power and immortality. He would later take the name Dr. Mist. He founded the ancient empire of Kor, with its 100 cities. Eventually Mist decided to abdicate and went to live in the mountain carved in his likeness on the East coast of Africa, where he remained. Having misused his powers at some stage in the past, Doctor Mist prefered to use it sparingly. In 1957, the European Economic Community established the Dome, a super-national police organization. Dr Mist founded the Global Guardians and Headquartered them in the Dome. The Global Guardians would work together for decades until they lost their funding to Justice League International and the Dome was closed. Queen Bee would rebuid the Dome in her country and brainwash the Global Guardians to work for her being led by an android Dr. Mist. Dr. Mist would appear and help Jack O' Lantern and Owl Woman escape Bialya. Doctor Mist would recruit a group to break the Global Guardians from their brainwashing and lead them to escape. He would later reform the Global Guardians and rebuild the Dome somewhere in the Pacific.
Mist was slain by an ancient force, although eternal, later showed up alive and well after the Zero Hour crisis. Calling himself Maltis, he formed a new group called the Leymen, later called Primal Force. The team was short lived and his stay was even less, having a heart attack shortly after their first mission. He was seemingly killed by being thrown into a pool of acid by Modrus. This may not be the final time we see Dr. Mist, who has been an immortal for over 11,000 years.
