New Genesis is an idyllic planet filled with unspoiled forests, mountains, and rivers. Populated by the benevolent New Gods, New Genesis is ruled by the Highfather and opposed by its twin-planet, Apokolips. While the planet's surface is populated by a sentient race known as the Bugs, the planet's only known urban location is Celestial City; a floating city populated by the New Gods that is designed to not affect the planet's surface in a bid to preserve the environment's natural beauty.
Following the end of the Third World that saw the destruction of the planet Urgund and the Old Gods, the rubble of Urgrund eventually formed into two planets. One was full of life and would be called New Genesis, while the other, a desolate wasteland, would be called Apokolips. As time passed, new life formed on both planets and they soon learned to access the same cosmic energies that their predecessors had. Soon after, they dubbed themselves "New Gods" in memory of the predecessors.
Moralistically divided, the people of New Genesis were led by Izaya the Inheriter while the New Gods of Apokolips were led by Yuga Khan, a position that was later taken by Darkseid. While not as militant as the Old Gods, the two sides fought from time to time due to the forces of Apokolips' wish to conquer and destroy all of creation.
Izaya gave some of his power to the New Goddess Atinai, allowing her to raise and shape a piece of New Genesis landscape and shape it into a massive flying city that she named the Celestial City, although it is referred to as "Supertown" by the young New Gods known as the Forever People.
Izaya and his wife, Avia, were one day ambushed by forces of Apokolips led by Steppenwolf and Uxas, and Avia was slain. In vengeance, Izaya led an attack on Apokolips and slew Steppenwolf. Revenge, however, brought no solace to Izaya, and he went on a sojourn into the wilderness of New Genesis, seeking enlightenment. It was at this time that Izaya first encountered the Source, and, taking the name Highfather, he returned to the gods of Supertown to bring them the Source's wisdom.
After years of war, the two worlds struck a peace accord, with Highfather engineering a pact with Darkseid, who had succeed the throne of Apokolips following Yuga Khan's imprisonment, by which Izaya's child was sent to the orphanages of Granny Goodness on Apokolips and Darkseid's son was sent to live on New Genesis as Highfather's adopted son.
Eventually, Highfather's son, Scott Free, escaped Apokolips with the Apokoliptian warrior, Big Barda, to Earth while Orion became a loyal follower and step-son to Highfather, with both sons battling Darkseid and his agents for years to come. Scott's escape, however, caused the pact to be broken and conflict between the two planets returned, with Darkseid eventually using the Micro-Mark (a weapon of minuscule size that is capable of destroying planets) to destroy New Genesis. However, the New Genesian New Gods survived by having Supertown relocate to another planet as New Genesis was rebuilt.
Upon learning of Darkseid's plans to destroy the Source Wall and control the Source itself, Highfather gathered other elder gods, including Zeus, Jove, Odin and Ares, to fight Darkseid. However, Ares rebelled against the other gods and killed Highfather. While Ares was later imprisoned within the new Source Wall, Highfather merged with the Source and Takion assumed the role as the new Highfather after Scott Free turned down the offer. Through Takion, Izaya was able to briefly return to resurrect Supertown to its former glory, giving the forces of New Genesis a new hope in the coming battles against Darkseid and his armies.
- New Genesis is an optional background for the player's Character Select Screen for those who have the Halls of Power Part II episode.
- New Genesis acts as the middle stage of the New Genesis Now operation.
- New Genesis first appeared in The New Gods #1 (February, 1971)
- The planet is surrounded by an energy envelope that places it slightly out of phase with the rest of reality; rendering conventional travel to the sector impossible. Travel to New Genesis is only possible via dimensional gateways known as Boom Tubes. As the gods of New Genesis are of gigantic stature, travelling through the boom tubes also rescales them to mortal proportions.
- While the majority of New Gods live in Supertown, a group known as the Primitives, led by Mother Herrae, bound themselves to nature and live a tribal existence upon the planet's surface.
- A Super-Cycle is a technologically advanced, quasi-sentient multi-cycle built by the Gods of New Genesis. Each Super-Cycle thinks, feels, and can even create new life. One Super-Cycle was utilized by the Forever People in their quest to defeat Darkseid on Earth. Another Super-Cycle was stolen over two thousand years ago by the Apokolips warrior known as "Rip Roar". He proceeded to plunder and cause havoc until he was sabotaged by Kalibak and both he and the cycle were entombed on Earth. They cycle was later discovered by Robin, Superboy and Impulse and was used as the team Young Justice's primary mode of transportation.
