Publication history
Created by Greg Potter and Gene Colan, Jemm first appeared in Jemm, Son of Saturn #1 (September 1984).

The first unofficial appearance of a Red Saturnian in DC Comics was Detective Comics #314 (April 1963) where he was a nameless alien criminal was weakened by motor oil, enabling the Martian Manhunter to defeat him.

According to Greg Potter, co-creator of Jemm, the character was originally conceived as the cousin of the Martian Manhunter. (Jogarr, Jemm's cousin in the series, was originally the Manhunter.) This was at a time when the Manhunter had disappeared from the pages of DC Comics for a time. However, part-way through developing the series, Potter was told by editor Janice Race that she had learned Manhunter would reappear in the Justice League of America. To avoid any continuity problems, Potter rewrote the series as Jemm, Son of Saturn, a character with no connection to the Martian Manhunter.

Jemm was reintroduced to the DC Universe by Grant Morrison in JLA #12, which emphasized his similarity to J'onzz. During his run on Martian Manhunter, John Ostrander used these similarities to explain that the Saturnians were a race created by and modelled on the Martians.
H'ronmeerca'andra

The three races of Ma'aleca'andra (the Martian name for the planet Mars in the DCU) are directly responsible for the H'ronmeerca's (Saturnians). The Saturnians are the genetically modified descendants from the underclass Martian worker clones created by their ancient Martian explorers as they ran Martian colonies on the moons of Saturn. The Martians cloned the original Saturnians from themselves; the Red Saturnians were created by the Green Martians while the White Saturnians were created by the White Martians. Both races of clones were created and bred to survive and live on the planet Saturn. The Green Martians treated their clones as equals while the White Martians treated their clones as slaves. The fate of the Yellow Martians is unknown during this time period.
The continued enslavement of the White Saturnians started a civil war between the two Martian races. At the war's conclusion the White Martians were exiled to the "Still Zone", only to escape years later and reappear disguised as the Hyperclan. After the civil war all Saturnians were granted their freedom, but continued to war amongst themselves for millennia.
Jemm, son of King Jaxx was forced to flee the palace after a White Martian coup. His mother Jarlla was able to hide him in a cave, where Jemm was trained by his White Saturnian teacher Rahani in the use of his powers.
Earth
After both his mother and teacher were killed by the White Martians, Jemm stole a ship and escaped to Earth, in search of his lover Syraa who had fled there earlier. He arrives in Harlem, New York and is befriended by an African-American orphan named Luther Mannkin. After a series of adventures with and without Luther, Jemm eventually found Syrra. They all then travelled to New Bhok, a Red Saturnian colony. Because he refused to take sides in a civil war on New Bhok Jemm was disavowed and cast out by both factions. Dispirited Jemm and Luther returned to Earth.
There Jemm learned that a criminal named Claudius Tull planned to use Saturnians as living energy sources. He had allied himself with a female White Saturnian named Synn. When Tull's true goal was exposed, Synn surrendered her forces to the Red Saturnian military. When last seen, Jemm had set out in search of Syrra, who had mysteriously disappeared yet again.
Injustice Gang
Jemm resurfaced years later as a member of the Injustice Gang. He had apparently been brainwashed by Lex Luthor through the use of a Philosopher's Stone and used as a psychic weapon against the Justice League. He was able to impersonate J'onn J'onnz (Martian Manhunter) telepathically. Plastic Man, disguised as the Joker, played several pranks designed to awaken him, but failed. J'onnz was able to sense and connect with Jemm's mind. J'onn powers freed Jemm, but left him comatose.
J'onn took Jemm to Z'onn Z'orr, his hidden Antarctic retreat in order to heal his mind. Jemm spent the next several months recovering his mental and physical health. He was later discovered, detained and abused by J'onn's evil brother Malefic, who convinced the JLA that J'onn had gone insane and was torturing Jemm.
While Jemm recovered at the JLA Watchtower, a delegation of Saturnians arrived to reclaim the prince. J'onn discovered that Jemm was to take part in a brokered political wedding designed to unite warring factions of Red and White Saturnians.
Rings of Saturn
During the trip to H'ronmeerca'andra, J'onn learned more about Jemm's future bride, a White Saturnian named Princess Cha'rissa. Cha'rissa became romantically attracted to J'onn, and he admitted his own attraction to her. The trio uncovered a plot by Jemm's White Saturnian cousin Jogarr to assassinate him, and Cha'rissa vowed to put aside her feelings for J'onn and be true to her intended, Prince Jemm. J'onn left for Earth just before the wedding ceremony.
Rann/Thanagar War
Though Jemm seems a pacifist, he joined forces with the Rannians in their war against Thanagar.
New Krypton
Jemm appears in Superman: World of New Krypton #9 (November 2009), and now appears to command all three known Saturnian races including the albino "Koolars", and the yellow skinned "Faceless Hunters".
When Mon-El brings the bottled city of the Lanothians to Titan, Jemm does not agree to allow the race of stronger telepaths live near his people. He later changes his mind when the Lanothians agree to live under his rule and rename themselves the Titanians.
