Earth-One was the designation for an Earth, and the Universe it inhabited, that existed prior to the Crisis on Infinite Earths.

Earth-One itself was populated by various individuals who resembled those of its primary Multiversal counterpart, Earth-Two. Some were direct parallels to their predecessors (ex. Superman (Earth-One) and Superman (Earth-Two)), some less so (ex. Atom (Al Pratt) and Atom (Ray Palmer)). The two Earths were closely linked in terms of parallel development, although Earth-Two individuals usually predated their Earth-One counterparts by a few decades.

The primary superheroes were limited to the western heroes of the eighteen hundreds and few others, until Superman arrived from Krypton and ushered in a new age of heroes. On this Earth, Superman had a career as Superboy and teamed with the Legion of Super-Heroes in the 30th century.

The Earth-One Flash, 1st Inter-Earth Traveller

From the perspective of the Earth-One Universe, the first travel to another parallel universe occured when The Flash (Barry Allen) accidently changed his vibrational frequency to match that of Earth-Two, where he met Jay Garrick, the Golden Age Flash. That meeting resulted in years of interaction between the original super-hero team, The Justice Society of America, and their younger Earth-One counterparts, The Justice League of America.

The Earth-Two Flash, Jay Garrick

As Barry Allen was the first traveller, the honor of naming the two earths fell to him - his universe's Earth was called Earth-One, Jay Garrick's became Earth-Two. As noted years later by the elder Superman, they (the JSA) were too polite to mention that they were around first [1].

As Allen explained to Garrick in their first meeting:

"..I vibrated so fast -- I tore a gap in the vibratory shields separating our worlds! As you know -- two objects can occupy the same space and time -- if they vibrate at different speeds!

My theory is, both Earths were created at the same time in two quite similar universes! They vibrate differently -- which keeps them apart! Life, customs -- even languages -- evoloved on your earth almost exactly as they did on my Earth! Destiny must have decreed there'd be a Flash -- on each Earth!
" [2]

During the Crisis on Infinite Earths, Earth-One was destroyed. The New Earth that emerged after the Big Bang possessed elements of Earth-One's history, along with elements similar to that of Earth-Two, Earth-Four, Earth-S, and Earth-X.

The JLA - Satellite Years


  • The Earth-One Universe is not known to have existed to the general populace of New Earth. Part of the Pre-Crisis Multiverse.
  • Earth-Two superheroes appeared in Earth-One comic books.


First Appearance: Usually denoted with the Showcase #4 with the first appearance of Barry Allen as the new Flash.

First Appearance of Barry Allen as The Flash

Earth-One was not given the actual designation ("Earth-One") until Flash (Volume 1) #123 in a story entitled The Flash of Two Worlds.

In current DC Comics policy, Barry Allen was the first visitor to a parallel Earth, although Wonder Woman (Earth-Two) had actually done so earlier, in 1953. [3]
