Doctor Mist has appeared in the pages of Super Friends, DC Comics Presents, Infinity, Inc., Justice League International, Justice League Quarterly, Blue Beetle and Primal Force.

Origin
Nommo, the wizard-king of the African empire of Kor, stood in the Pillar of Life and was endowed with immortality. He later took the name Doctor Mist.

Global Guardians (Pre-Crisis)
Doctor Mist gathers a number of international heroes to help the Super Friends battle the Conqueror. Later, Superman teams with several international heroes at Doctor Mist's request. He is the one who first gives them the name The Global Guardians. Superman and several of the Guardians would team up to fight against the threat of Thaumar Dhai and the squad of powerful wizards who worship him. Dhai was defeated when his objects of power turned out to be Superman-created fakeries. The team later fights against the Shadow Demons in the Crisis on Infinite Earths. Most of the Pre-Crisis history of the Global Guardians is no longer in the mainstream continuity of the DC Comics universe.

Global Guardians (Post-Crisis)
In 1957, the newly formed European Economic Community established the Dome, a supra-national police organization. At some later point Doctor Mist formed the Global Guardians to serve as a task force for the Dome.

Decades later, the Dome lost its funding when, in part because of the political machinations of Dr. Klaus Cornelius, the United Nations decided to close the Dome and instead fund the new Justice League International. The Global Guardians then fractured with Doctor Mist and his assistant Belphegor, disappearing. Queen Bee of Bialya rebuilt the Dome in her country. She then brainwashed the Global Guardians into her service also creating an android Doctor Mist to lead the team.

Later on, Doctor Mist reappeared and helped Guardian members Jack O'Lantern and Owlwoman escape Bialya. Doctor Mist recruited a team to free the rest of the Guardians from Bialya mind control and then reformed the Global Guardians, building a new Dome headquarters somewhere in the Pacific.

Primal Force
An eternal, Mist's physical body was slain by an ancient force. Nonetheless, he did turn up alive and seemingly well after the Zero Hour crisis. At this time, calling himself Maltis, he formed a new team of heroes known as the Leymen. The group was short-lived. Maltis' time on the team even shorter as he had a heart attack soon after the team formed. Later, he was seemingly killed after being thrown into a pool of acid by the evil Mordru.

The New 52
In September 2011, The New 52 rebooted DC's continuity. In this new timeline, Steve Trevor first mentions Mist as a government operative, having a hand in watching the Black Room, a secretive government vault where mystical artifacts are stored. Trevor sends the Justice League Dark to rescue Mist after he is captured while infiltrating Felix Faust's cult in South America. Mist appears to have an existing friendship with Black Orchid, one of Trevor's other magical operatives. However it is then revealed that Mist has been working for Faust all along, as Mist sends a magical blast straight into John Constantine's brain. Mist had been a double agent all along, designed to get Faust into the Black Room. In the end, Faust had promised to return Mist's deceased wife back to him.

Powers and abilities
As a result of his exposure to the Pillar of Life, Doctor Mist was endowed with immortality. He can also cast spells of illusion and enchantment, and according to one of his origins use to craft magical gems.

In other media
Doctor Mist, under his real name Nommo, appears in the Constantine episode "A Feast of Friends", portrayed by Charles Parnell. He is depicted as a shaman who helps John track a hunger demon by entering a hallucinogenic state using a drug called "mist". After the hunger demon Mnemoth began a rampage, John Constantine contacted Nommo to find a way to defeat it. They used the strong psychedelic drug The Mist to trace its origins, before Nommo gave Constantine and himself the Nectar of Nhialic to counteract the trip.
