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.
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.
- In Earth-Two's version of the months leading up to WWII, the Axis Powers included: Austria, Bulgaria, Croatia, Dukalia, Germany, Hungary, Italy, Japan, Napkan, Nural, Oxnalia, Romania, Syronia, Toran, Twerpan, and others.
- In Earth-Two's version WWII, the neutral and overrun nations included: Bahdnisia, Boravia, Galonia, Kurtavia, Luthoria, Numark, San Monte, and others.
- After America's entry into WWII during December 1941, the fictional evil nations seemingly disappeared.
- Earth Two's history includes a number of catastrophic events, including terrorist attacks and world-takeover attempts, in addition to WWII and subsequent "real world" wars. Most of these events were never mentioned again in any subsequent story. These included:
- Washington, D.C.:
- New York City area:
- New York City was flooded in 1939, 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.
- An unknown number of subway passengers were electrocuted by Doctor Hastor's electrical weapon in 1940..
- Several large buildings in the downtown area got knocked down by Alexander the Great's gravity weapon in 1940.
- A big suspension bridge in the New York City area was destroyed by Hugo Vreekill's metal-dissolving weapon in 1940.
- The entire populations of two cities near Cliffland were found dead, in 1941.
- 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.
- An airship-based attack using Jonathan Klegg's Fireball Launcher caused widespread destruction and panic, and an unknown casualty count, in mid-1941.
- Another aerial attack using Ivan Borloff's metal-dissolving ray also caused widespread destruction and panic, and a terrible casualty count, in mid-1941.
- 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.
- 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. The chronicles make no mention of this hideous edifice ever being removed or dismantled.
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, both 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-Two was given to the anti-matter Earth populated by the Third incarnation of the Crime Syndicate, as at the time it was the only verifiable "other" Earth known to the DC Primary Earth. Many readers still refer to the antimatter reality as "Earth-Two" while others now address it as "antimatter Earth-Two" and "Crime Syndicate Earth" now.
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.

- Earth-Two superheroes appeared on Earth-One beginning with 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.
- 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. . However the general populace of these other Earths were ignorant of the existence of Pre-Crisis Earth-Two.
- Many, though not all, Golden Age stories have been retroactively attributed to Earth-Two continuity. The original Earth-Two history was based on much of the mainstream DC Comics stories published between 1935 and 1955 and were considered to be part of the greater Earth-Two environment, though some aspects of the original stories of the primary heroes including Superman, Batman, and Wonder Woman of Earth-Two were later retconned heavily to be different from the actual books of that era such as Earth-Two Superman marrying Lois Lane in the early 1950s and becoming editor-in-chief of the Daily Star and Batman marrying a reformed Catwoman in 1955.
- Many readers today usually denote the Golden Age Characters to mean the actual characters who actually appear in the books of this era. Though some still call the Earth-Two characters as the Golden Age version, despite the Earth-Two characters being very different from the actual characters in the books of that era.
- To address some of these differences an "Alternate Earth-Two" was suggested by E. Nelson Bridwell in the Superman Family letters page.
- "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.
- Following the events of Infinite Crisis as well as that of 52, the Multiverse was created anew with fifty-two distinctive alternate realities, each one designated with a number between one and fifty-two. One of these realities is Earth-2. Although the current Earth-2 bears some similarities to the Pre-Crisis Earth-Two as in its superhuman populace, the new Earth-2 is a completely separate and distinct reality with its own different background and time frame. The general populace of New Earth are also unaware of the new Earth-2 universe.
- Post Flashpoint a totally different Earth 2 appeared but 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.
- The term "Earth-2" has been used to refer to other Earths:
- The DC Primary Earth was named "Earth-2" by the Anti-Matter Lex Luthor in JLA: Earth-2
- Marvel's Earth-616 in JLA/Avengers Vol 1 3 is called "Earth-2" by Hal Jordan.
