Earth-One (also Earth-1) is a name given to two fictional universes (The Pre-Crisis and Post-Crisis versions of the same universe) that have appeared in American comic book stories published by DC Comics. The first Earth-One was given its name in Justice League of America #21 (August 1963), after The Flash #123 (September 1961) explained how Golden Age (Earth-Two) versions of characters such as the Flash (Jay Garrick) could appear in stories with their Silver Age counterparts (Barry Allen). This Earth-One continuity included the DC Silver Age heroes, including the Justice League of America.

Earth-One, along with the four other surviving Earths of the DC Multiverse, are merged into one in the 1985 miniseries Crisis on Infinite Earths. This Earth's versions of characters were primarily the Earth-One versions (i.e. Superman, Batman), but some characters from the four other worlds were also "folded" in. In Infinite Crisis, Earth-One was resurrected and merged with the primary Earth of the publication era to create a New Earth that brought back more aspects of Earth-One's original history. In 2007, a new version of Earth-One was created in the aftermath of events that occurred within the 52 series.

Characters from DC Comics were originally suggestive of each existing in their own world, as superheroes never encountered each other. This was soon changed with alliances being formed between certain protagonists. Several publications, including All-Star Comics (publishing tales of the Justice Society of America), Leading Comics (publishing tales of the Seven Soldiers of Victory) and other comic books introduced a "shared-universe" among several characters during the 1940s until the present day.

Alternative reality Earths had been used in DC stories before, but were usually not referred to after that particular story. Also most of these alternative Earths were usually so vastly different that no one would confuse that Earth and its history with the so-called real Earth. That would change when the existence of another reliable Earth was established in a story titled "Flash of Two Worlds"[1][2] in which Barry Allen, the modern Flash later referred to as Earth-One (the setting of the Silver Age stories) first travels to another Earth, accidentally vibrating at just the right speed to appear on Earth-Two, where he meets Jay Garrick, his Earth-Two counterpart.

Major events


Crisis on Infinite Earths (1985–1986) was an effort by DC Comics to clean up their continuity, resulting in the multiple universes, including that of Earth-One, combining into one. This involved the destruction of the multiverse, including Earth-One and the first appearance of the post-Crisis Earth.

Post-52 version

Main article: Earth One (DC graphic novel series)

At the end of the Infinite Crisis limited series, the realigned world is called "New Earth". There are now 52 universes: "New Earth" (aka Earth-0), and Earths-1 to 51. In the final issue of the 52 weekly series, it is revealed that fifty-two duplicate worlds have been created and all but New Earth have been altered from the original incarnation.[27]

Earth-1 is featured in the Superman: Earth One[28][29] and Batman: Earth One[30] graphic novels.[31]


Notes New Earth / Prime Earth
Kal-El/Clark Kent Since Superman was one of several DC characters continuously published throughout the 1950s, there is not a clear dividing line between the Earth-One and Earth-Two versions of Superman. Several stories published before the mid-1950s took place on Earth-One. Also, any Superman stories published before the mid-1950s that featured or mentioned Superboy also took place exclusively on Earth-One, as the Earth-Two Superman, per the earliest Superman comics, never had a Superboy career. His first appearance in comics was in Superman vol. 1 #46 (May 1947), the first time Superboy was referenced in a Superman story. This version of Superman remained in publication until 1986, as the miniseries Crisis on Infinite Earths (1985–86), he was written out of continuity with John Byrne's miniseries The Man of Steel. Superman
Bruce Wayne Batman is not significantly changed by the late 1950s for the new continuity. Batman is not significantly updated in the manner of other characters until Detective Comics #327 (May 1964), in which Batman reverts to his detective roots, with most science-fiction elements jettisoned from the series. Details of Batman's history were altered or expanded upon through the decades. Additions include his upbringing by his uncle Philip Wayne after his parents' death. In 1969, Bruce moves from his mansion, Wayne Manor into a penthouse apartment atop the Wayne Foundation building in downtown Gotham City, in order to be closer to Gotham City's crime. Batman spends the 1970s and early 1980s mainly working solo, with occasional team-ups with Robin and/or Batgirl. Batman's adventures also become somewhat darker and more grim during this period, depicting increasingly violent crime. This version of Batman remained in publication until 1986, as the miniseries Crisis on Infinite Earths (1985–86), he was written out of continuity. Batman
Alexis "Lex" Luthor Luthor grew up in the suburbs of Smallville with his parents and sister. As a teenager, Luthor learned about the existence of Smallville's own hometown hero, Superboy. After a fire in his lab, which resulted in losing both his hair and all of his experiments. Superboy saved him from the fire but Luthor accused the hero of destroying his experiments on purpose out of jealousy. From that moment onward, Lex Luthor became the sworn enemy of Superboy. Fearing that their son would never reform his ways, Lex's parents decided to move away from Smallville and changed their name to "Thorul" in hopes to raise their daughter in a relatively peaceful life away from the evil Lex. During one of his outer space explorations Lex would find Lexor, a planet which would become his primary refuge from the rest of the galaxy. The people of Lexor accepted Lex as their hero and First citizen. Lex would mostly settle down on Lexor taking a wife, Adora, and fathering a son. Lex would largely remain on Lexor until the planet was destroyed by his really never-ending battle with Superman. Lex Luthor
Dru-Zod Zod is a megalomaniacal Kryptonian, in charge of the military forces on Krypton. He knew Jor-El, when he was an aspiring scientist. When the space program was abolished after the destruction of the inhabited moon Wegthor, he attempted to take over Krypton. He was sentenced to exile in the Phantom Zone for 40 years for his crimes. Zod was eventually released by Superboy when his term of imprisonment was up. However, he attempted to conquer Earth with his superpowers acquired under the yellow sun. With his threat now obvious, Superboy was forced to oppose him and ultimately returned him to the Zone. General Zod
