     Reality names were reused several times. See also Earth-Two-A, Earth-2, Earth 2, JLA: Earth-2, Arrowverse: Earth-2, Smallville: Earth-2.

Earth-Two was the reality designation attributed to the planet Earth, and the Universe it inhabited, that existed prior to the Crisis on Infinite Earths.

Earth-Two itself was populated by various individuals who resembled those of its primary Multiversal counterpart, Earth-One. 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. For a complete list of Earth-Two inhabitants, see List of Earth-Two Characters.



Earth-One and Earth-Two vibrate differently; thus, time is slower on Earth-Two. Every twelve months, the temporal matrices of the two universes come together briefly; during this "closest orbit", for 21 days, it is easier to cross the dimensional barriers between them.[1]

Prior to the events of the Crisis on Infinite Earths, the reality termed as Earth-Two was populated by heroes who emerged during the Golden Age, including the Justice Society of America and the native incarnations of Superman (Kal-L), Batman (Police Commissioner Bruce Wayne), Robin (Ambassador Richard "Dick" Grayson) and Wonder Woman (Princess Diana Trevor, wife of U.S Army General Steve Trevor) to this reality all emerged prior to the Japanese attack on Pearl Harbor which led to the United States' involvement in World War II.

World War II

"Forgotten" Catastrophes

  • Earth-Two had several close parallels one of which was "Alternate Earth-Two" (Earth-Two-A).[33] Because of this great care has been taken in saying that any catastrophic event, including terrorist attacks and world-takeover attempts, is part of Earth-Two history especially if the event is never mentioned again in any subsequent story.[34] Such events include:
    • Washington, D.C.:
      • In 1936 the Capitol Building was destroyed by a gang of gas-masked terrorists, using a large armored tank.[35] This same terrorist gang dropped bombs, from autogyros, to destroy the Plymouth Bridge.[36]
      • In 1939 the Capitol Building was destroyed again, as was the U.S. Treasury, by Prof. James Barton, using radio-controlled missiles.[37]
      • In 1940 the White House and the Washington Monument were destroyed by invisible invading aliens.[38]
    • New York City area:
      • New York City was flooded in 1939,[39] due to polar icecap melting, caused by Berhener's heat ray.
      • New York City was attacked from the air by Dr. Carl Kruger and his Scarlet Horde, with zeppelins and death rays, killing hundreds, in 1939.[40]
      • The Avenger's Disintegrator Ray destroyed a church, killing thousands of people, then was used to destroy a battleship and an important dam, in 1939.[41]
      • Artificial lightning strikes were used, in 1940, to bring New York City under the control of "The Master" and his Fascist accomplices.[42]
      • In 1940 the Empire State Building, the Hudson Railroad, two city blocks of New York office buildings, and every newspaper plant in New York City were destroyed by invisible invading aliens.[43]
      • An unknown number of subway passengers were electrocuted by Doctor Hastor's electrical weapon in 1940.[44]
        • Unlike most of these disasters, this incident was mentioned afterward, one time, in a conversation among the newly-formed All-Star Squadron.[45]
      • Several large buildings in the downtown area got knocked down by Alexander the Great's gravity weapon in 1940.[46]
      • Several big suspension bridges in the New York City area, including the Great West River Bridge and at least one other, were destroyed by Hugo Vreekill's metal-dissolving weapon in 1940.[47]
      • Again in 1940, in New York City, several skyscrapers were shattered with terrible rays; thousands of civilians were killed in the wreckage.[48]
      • The entire populations of two cities near Cliffland were found dead, in 1941.[49]
      • Also in Cliffland in 1941, an entire section of the city was destroyed in a volcanic eruption, then giant icebergs knocked down several skyscrapers, and then the city was flooded to a depth of several stories, with thousands of casualties in all three events.[31]
      • Another aerial attack using Ivan Borloff's metal-dissolving ray also caused widespread destruction and panic, and a terrible casualty count, in mid-1941.[50]
      • An airship-based attack using Jonathan Klegg's Fireball Launcher caused widespread destruction and panic, and an unknown casualty count, in New York City, in mid-1941.[51]
      • In 1943, Wonder Woman knocked the Statue of Liberty off its island and into the harbor.[52]
    • Also in 1939, another American town, Cornyville, was wiped out by Mobrune's "Snow Death" toxin.[53]
    • Nation-Wide:
    • Africa & Arabia
      • Ulonda, a little-known city in the Sahara, and a rich source of radium, was attacked by a renegade warlord, Zolar, with a fleet of radium-powered sky-ships, armed with the "meteor death" weapons, which rained deadly orbs onto the city, engulfing Ulonda in awful destruction, killing probably hundreds and perhaps thousands, of Ulondian civilians.[56]
      • The Great Sphinx at Giza, Egypt, was smashed to pieces by Wonder Woman, and reassembled by Starman, in 1943.[57]
    • Africa & Europe
      • Several coastal cities in Africa and Europe were attacked, by Moon Men, with iradium gas, killing thousands, in early 1941.[58]
    • Asia
      • In the Himalayas, using a machine gun and an improvised sling, Captain Desmo and his assistant wiped out the entire "Mudas" tribe of Himalayan giant humans.[59] This genocide was never again mentioned afterward.
    • Latin America:
      • Mexico City: Amid a bloody, supernaturally-instigated, race war, an enormous Aztec-style step-pyramid emerged from the pavement in the center of town, creating massive destruction among surrounding streets and structures, to loom over the entire city. Afterward the participants had only confused and incomplete memories of this carnage, and many of their fellow citizens were dead.[60] The chronicles make no mention of this hideous edifice ever being removed or dismantled.
    • World-Wide:
      • In 1924, from July 7th until July 14th, it rained continuously, everywhere on Earth, except for one house.[44]
      • In 1941, the Earth's rotation was halted by Adam Igorovich's scientific machinery, and then the Earth was drawn closer to the sun.[61]
      • A piece of the planet Neptune broke off, flew across the Solar System, and landed on Earth, forming a new continent, called Neptunia. Devastating earthquakes wracked the entire world.[62]


During the Crisis on Infinite Earths, Earth-Two ceased to exist, though aspects, characters and localities from it were effectively merged with aspects of Earth-One, Earth-Four, Earth-S and Earth-X to form one composite universe. The most noted surviving aspect was many of the non-duplicate heroes (including members of the Justice Society such as Jay Garrick, Alan Scott and Ted Grant) were recreated to be native to the New Earth reality.

By some yet unexplained occurrence, Kara Zor-L (known as Power Girl) and Per Degaton both survived the historical elimination of Earth-Two, and retain their original multiverse Earth-Two origin basis.

After the Crisis on Infinite Earths, the designation of "Earth-2" was given to New Earth by the Alexander Luthor of the antimatter Earth that was populated by the third incarnation of the Crime Syndicate. Due to the way the JLA: Syndicate Rules back cover reads some readers think "Earth-2" refers to the antimatter reality when it in fact referred to the DC Primary Earth.


Copies of some Earth-Two characters appeared as "ghosts" in the superhero-themed restaurant Planet Krypton which in reality was an arsenal.[63][64] Among the weapons in the restaurant was Alan Scott's power ring (along with Power Ring's and a regular Green Lantern ring). An Earth-Two like Superman is shown trying to penetrate a barrier around his city[65] and later realizes he has a door "even if he is not going to use it. Not today anyway."[64]

It is later revealed that hypertime played a part in the creation of a nearly identical Earth-Two analog.[66]

Infinite Crisis

A copy of the Pre-Crisis Earth-Two was briefly made, along with other divergent realities, during an event called "Infinite Crisis". This incident saw the return of two Earth-Two's original denizens Kal-L (Superman) and his wife Lois Lane Kent, both of whom had disappeared into a paradise-like dimension following the events of the first Crisis. Accompanying them was Alexander Luthor - the sole survivor of Earth-Three and architect behind Earth-Two's re-creation and Superboy-Prime. This duplicate Earth-Two was barren and unpopulated and was ultimately recombined into New Earth at the end of Infinite Crisis.

In the Thy Kingdom Come storyline after the Earth-22 Superman appeared Wally West and Jay Garrick use the cosmic treadmill an attempt to visit Earth-Two and along the way they glimpse what looks like Earth-Two before arriving in the void that was Earth-Two. Later Power Girl is transported to that Earth which not only remembers "red skies" (a common reference to Crisis) but seems to be a carbon copy of the old Earth-Two; problem is it already has a Power Girl. Starman eventually reveals that Alexander Luthor's actions rebirthed the multiverse which is why the revived Earth-Two had its own Power-Girl (and why its Krytonite effected the New Earth Power Girl).


The actions of Brainiac, Parallax and the Superman of New Earth undid the events of the original Crisis, restoring Earth-Two and the rest of the infinite Earths to the Multiverse.

Unusual Astronomy: Inhabited Planets


 Main article: Earth-Two Characters


The properties of matter, laws of physics and principles of chemistry were very different on Earth-Two from those of our own world, or of "nearby" parallel continuums either.

  • Elements such as Amazonium, Kryptonite and Nth Metal exist on Earth-One and in several "nearby" parallel universes, such as Earth-Two and Prime Earth, while seemingly not existing on others, such as Earth-S and the Quality Universe. Not only are different sets of elements and materials available, but different sets of physical laws prevail. For example:
  • There is no record of a "Speed Force" at work in Earth-Two.
  • In Earth-Two, unlike our own world, it is possible to concoct drugs that would work only for a specific period of time, such as Miraclo, or would only take effect after a certain time, like Joker Venom.

  • Earth-Two superheroes appeared on Earth-One beginning with The Flash #123. The concept of Earth-Two was developed by writer Gardner Fox after an initial concept by Julius Schwartz.
    • However, Schwartz's initial idea was that the original Golden Age characters existed in "Earth 1" and the current Silver Age characters in "Earth 2". This concept was mixed up, resulting in the current universe designation.[186]
  • The existence of the Pre-Crisis Earth-Two Universe was known to the superhuman (both heroic and villainous) populace of Earth-One and several other Earths including Earth-X and Earth-Three.[187]. However the general populace of these other Earths were ignorant of the existence of Pre-Crisis Earth-Two.
  • Convergence #0 states the first appearance of "Pre-Crisis Earth-Two Metropolis" was in The Flash #123 (rather then Action Comics #16). Since the city of Metropolis itself doesn't appear in that issue (The action on Earth-Two is limited to Keystone City) that means that The Flash #123 is where Earth-Two itself first appeared. This means that where ever the majority Golden Age stories occurred it was not the Earth-Two introduced in The Flash #123. For simplicity it will be assumed that several hypertime realities interacted with Earth-Two "distorting" events.
  • "Golden Age" Earth-Two was retroactively wiped out of existence (as with the rest of the Pre-Crisis Multiverse due to events in Crisis on Infinite Earths with a close (if not exact copy) copy created at the end of 52. Flashpoint saw a very different Earth 2 and according to Jeff King "Post-Convergence, every character that ever existed, in either Continuity or Canon, is now available to us as storytellers." which means that Earth-Two, Earth-2 and Earth 2 now all exist.
