Earth-Prime

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

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.

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. 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. 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.

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.

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. 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."
