Earth-Prime is one of the infinite number of divergent realities that made up the pre-Crisis on Infinite Earths Multiverse.

Background Information

In the original Multiverse, Earth-Prime was presented as the "real" Earth, the actual reality where the readers lived. DC Comics operated as a publisher and all superheroes are fictional.

However, Earth-Prime is shown to be an alternate reality when the Flash (Barry Allen) accidentally travels there from Earth-One. The Flash, stranded, contacts DC Comics editor Julius Schwartz, who helps him construct a cosmic treadmill to return to Earth-One. Eventually it was stated that the writers of DC Comics of Earth Prime unconsciously base their stories on the adventures of the heroes on Earth-One and Earth-Two.[1]

In another Flash story, Earth Prime's Cary Bates travels to Earth-One, where he discovers that the stories he writes are not only based on events on Earth-One but can actually influence these events as well.[2] This power turns for the worse when Bates is accidentally transported to Earth-Two. The interdimensional trip temporarily turns Bates into a supervillain, and he quickly kills the Justice Society of America.[3] Luckily, fellow DC writer Elliot S! Maggin, with the help of the Justice League and the Spectre, is able to restore matters on both Earths.[4]

Earth-Prime is not without its own heroes:

The first notable hero, is 'Ultraa,' the sole survivor of a destroyed alien world, rocketed to Earth-Prime as a baby. After his first encounter with the Justice League, Ultraa decided Earth-Prime was not ready for superheroes and relocated to Earth-One.[5]

The second superhero became known as 'Superboy-Prime.' This Superboy's powers first manifested around the time of the passage of Halley's Comet on Earth-Prime. Just after manifesting his powers, Superboy-Prime met Earth-One's Superman.[6] Very soon thereafter, Earth-Prime was destroyed in the Crisis on Infinite Earths. Superboy-Prime escaped his universe's destruction and later joined Earth-Two's Superman and Lois Lane Kent and Earth-Three's Alexander Luthor in a "paradise dimension."[7]
