Seven Soldiers of Victory
Earth-Two is a fictional universe appearing in American comic book stories published by DC Comics. First appearing in The Flash #123 (1961), Earth-Two was created to explain how Silver-Age (Earth-One) versions of characters such as the Flash could appear in stories with their Golden Age counterparts. This Earth-Two continuity includes DC Golden Age heroes, including the Justice Society of America, whose careers began at the dawn of World War II, concurrently with their first appearances in comics. Earth-Two, along with the four other surviving Earths of the DC Multiverse, were merged into one in the 1985 miniseries Crisis on Infinite Earths. However, following the events of Infinite Crisis, the Multiverse was reborn, although the subsequent Earth-Two was not the same as its pre-Crisis equivalent.
Following the events of Flashpoint, Earth-2 underwent an additional reiteration. While it still houses a Justice Society of America, its membership are now younger than their Prime Earth parallels and have undergone a devastating interstellar war with Darkseid's horde of alien invaders from Apokolips. In the process, Superman, Batman and Wonder Woman were believed to be killed, although Earth-2's Superman is later revealed to be alive. In addition, Earth-2's Robin and Supergirl have been swept through a dimensional warp to Prime Earth and are now known as Power Girl and The Huntress.
Flash of Two Worlds
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. 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" 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. He claims Gardner Fox's dreams were tuned into Earth-Two. Superman "Kal-L" is the first major reliable costumed superhero to surface on Earth-Two, discounting earlier part-time heroes such as Dr. Occult. Most of the following costumed mystery-men history is based on the Earth-Two Superman's initial appearance, where these previously independent operating heroes begin to reliably interact. In order to distinguish him from the later primary version of the character, this Superman is called "Kal-L", using the spelling of Superman's Kryptonian name in his early appearances. He was specifically introduced as an Earth-Two character in Justice League of America #73 (1969). Most superheroes from the Golden Age later followed this trend of operating publicly, while wearing distinctive costuming and interacting in a largely shared universe. The primary characters of Superman and Batman still largely worked independent of team environments.
Infinity, Inc., a group made up of the children and heirs of the Justice Society, was introduced in All-Star Squadron #25 (September 1983). There was an eponymous comics series starring the group, which ran from March 1984 through June 1988.
Destruction: Crisis on Infinite Earths
Crisis on Infinite Earths (1985–1986) was an effort by DC Comics to clean up their continuity, resulting in the multiple universes combining into one. Since then, a handful of characters originating from Earth-Two have consistently remained part of the merged Earth, including Power Girl, Jay Garrick, and Alan Scott. Superman and Lois Lane from Earth-Two (along with Superboy from Earth Prime, and Alexander Luthor, Jr. from Earth-Three) were transported into a ghost-like "paradise dimension" tangential to the new universe.
Following the end of the known Multiverse, more alternate realities were discovered. Even though Earth-Three was destroyed in the Anti-Monitor's anti-matter wave attacks, a new Crime Syndicate (called the "Crime Syndicate of Amerika") developed in the antimatter universe of Qward, which was very different in background and power base from the pre-Crisis Earth-Three group, though same in the number of members. After the Kingdom event, Hypertime and divergent realities were revealed, but never supposed to be accessed, as stated in the Zero Hour event. They were later revealed when a directly-parallel Flash (Walter West aka the "Dark Flash") entered the mainstream DC Universe and threatened to destroy it. These alternate realities are usually addressed as "Elsewhere" and "Elseworld" stories.
Kal-L, Lois Lane-Kent, Superboy-Prime, and Alexander Luthor returned during Infinite Crisis. Unknown to Kal-L, Luthor's plan was to resurrect the pre-Crisis Multiverse. He wanted to mix and match elements from each reality to create a "perfect world". The fallout of the conflict brought the short-lived return of an Earth-Two copy and the deaths of Kal-L, Lois Lane-Kent and Luthor Jr. of Earth-Three. It is unclear what happened to the aged Diana Trevor, the Earth-Two Wonder Woman, though she faded from her ghostly existence. Inexplicably, Earth-Two was the only returning world that was devoid of most people, except the Justice Society, Kal-L, and his wife Lois Kent. This world was a copy, new and recently manufactured by Alexander Luthor, Jr. of pre-Crisis Earth-Three, instead of resurrected. This copy Earth-Two was recombined with the primary Earth to form the primary DC reality termed as "New Earth".
At the end of the Infinite Crisis limited series, the realigned world is called "New Earth". 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. The post-Crisis Earth-2 made its first appearance in a single panel of 52 Week 52 where it resembled the pre-Crisis Earth-Two, where a newspaper article says that this world's Superman and Power Girl are missing. The Flashes of New Earth (Jay Garrick and Wally West) briefly glimpsed this world with Robin and Huntress in action (during their travel with the Cosmic Treadmill as shown in Justice Society (vol. 3) #11) and Monarch selected Jay Garrick of this Earth (amongst others) in a Multiversal arena tournament. Based on comments by 52 co-writer Grant Morrison, this alternate universe is not the pre-Crisis Earth-Two.
This separation between the pre-Crisis Earth-Two and post-Crisis Earth-2 is formally established in Justice Society of America Annual #1 (2008) with a story titled "Earth 2, Chapter One: Golden Age", where the New Earth Power Girl arrives on post-Crisis Earth-2. Thinking that she has had her most longing desire fulfilled of "returning home" to her long destroyed source reality of pre-Crisis Earth-Two somehow by Gog, Power Girl crash lands unconscious on the closest parallel of the 52 Multiverse, post-Crisis Earth-2, which appears similar to the pre-Crisis Earth-Two. She is found by the post-Crisis Earth-2 Huntress, who thinks her to be her long-missing best friend, the Power Girl native to this world. In this new reality, the Justice Society of America has merged with Infinity, Inc. and is now known as Justice Society Infinity. Initially, Power Girl believes she has returned home, until the missing post-Crisis Earth-2 Power Girl reappears and declares that the other Power Girl is an impostor and has caused the disappearance of the post-Crisis Earth-2 Superman which results in the post-Crisis Earth-2 Power Girl and the Justice Society Infinity to go after the New Earth Power Girl.
The Power Girl of New Earth recruits the post-Crisis Earth-2 Michael Holt, who is a physics professor and father and has never become a costumed hero, to help her return to her source Earth. Holt constructs a device similar to the Cosmic treadmill used by Barry Allen to open a portal to New Earth. The Power Girl of New Earth returns home, followed by the Justice Society Infinity, who kidnap her and take her back to post-Crisis Earth-2. During the confrontation, Green Lantern and Jade are initially confused when they see each other, as the post-Crisis Earth-2 Jade's father, Alan Scott, is dead, and New Earth's Jade is dead as well. The JSI interrogate Power Girl for information on the post-Crisis Earth-2 Superman's whereabouts. The post-Crisis Earth-2 Power Girl assumes that the Superman the New Earth Power Girl said was dead was the post-Crisis Earth-2 Superman (rather than Kal-L who was killed by Superboy-Prime) and that the New Earth Power Girl had killed him. The Justice Society of New Earth arrives to stop her torture. Starman reveals that the re-creation of the Multiverse led to the creation of a Power Girl and Superman native to this new universe, post-Crisis Earth-2 and that the post-Crisis Earth-2 Superman is still alive. The Power Girl of New Earth then returns home along with her Justice Society but with no apology from her counterpart nor from the post-Crisis Earth-2 Huntress for their actions against her.

The Earth-2 concept has been revived as part of the publisher's The New 52 event, following another reboot of the DC Multiverse. The universe is covered in two series; Worlds' Finest, which focuses on the adventures of the Huntress and Power Girl on New Earth and which is currently (as of 2014) written by Paul Levitz, and Earth 2, written by Tom Taylor, which features the formation of the Justice Society. James Robinson, the original writer of Earth 2, describes the new Earth 2 as a complete reboot of the concept, with superheroes only just now appearing, similar to the "young hero" concept for the New 52 continuity, and with revamped costume designs.
In Earth 2, Superman, Batman, and Wonder Woman seemingly gave their lives in order to repel the Apokoliptan invasion, leaving behind a world with no heroes. Supergirl and Robin (Helena Wayne) end up stranded in the mainstream universe towards the end of the invasion. When the Earth-2 Solomon Grundy threatens the world, three new heroes team up to defeat him: the Flash (Jay Garrick), Hawkgirl (Kendra Saunders), and Green Lantern (Alan Scott). In later issues, Mister Terrific (Michael Holt) from the mainstream universe joins the team. Other heroes who have made appearances include Dr. Fate (Khalid Ben-Hassin), the Atom (Al Pratt), now nuclear-powered, the Sandman (Wesley Dodds), Mister Miracle, and Big Barda. Villains include Solomon Grundy, a now-villainous Terry Sloane, Wotan, Steppenwolf and what was thought to be a surviving, Darkseid-brainwashed Superman, which turned out to be a very powerful but genetically unstable Bizarro-type clone. Writer James Robinson left the series with issue #16 and Tom Taylor became the new writer at #17. Other new characters to be introduced as the series progresses include a female Red Tornado (with the memories and personality of Lois Lane), a hyper-intelligent knowledge-assimilator known as Accountable (Jimmy Olsen), a new Batman (Thomas Wayne using Miraclo), a new version of Aquawoman (Marella), and another Kryptonian, Val-Zod, who had been imprisoned by Terry Sloane.
In classic Earth-Two stories, Quebec is shown to be an independent nation autonomous from Canada. Among other deviations from real world history, South Africa had abolished apartheid sooner, and the Atlantean countries of Poseidonis and Tritonis were ruled by a queen, not a king (along with its inhabitants displaying surface dweller features and no capacity for underwater survival, as the Atlantis continent had been raised).
In addition, masked crimefighters are introduced decades earlier than in other universes later identified within DC Comics, and these participated in such historic conflicts as World War II. Franklin Delano Roosevelt founded both the Justice Society of America and the All-Star Squadron. Other events taking place decades earlier include the destruction of Krypton and the advent of advanced technology including interstellar transportation and time travel. Thousands of years ago, the Guardians of Earth-One's Universe expelled the vast majority of magic from their universe, sending it to Earth-Two's. This resulted in a predominance of magic and a weakening of scientific laws within Earth-Two's universe.
The following is a list of Earth-Two superheroes1 that have other earthly counterparts (most often Earth-One) or who immigrated from Earth-Two.
The New 52
|Notes||New Earth / Prime Earth
|Kal-L/Clark Kent/Superman||Kal-El/Clark Kent/Superman||Superman was born on the planet Krypton, and arrived on Earth as a baby near the start of Earth's First World War. As Clark Kent, he was a reporter for the Daily Star, eventually becoming editor-in-chief and marrying its star reporter Lois Lane. Although he was retconned out of existence by the events of Crisis on Infinite Earths and All-Star Squadron #60, he was restored to continuity in The Kingdom #2. He was killed by hero-turned-villain Superboy-Prime in Infinite Crisis #7, but later resurrected as a Black Lantern, along with his wife Lois.
In the New 52, Kal-El is far younger than the original Earth-Two version and only a little older than the mainstream Superman. His aged foster parents both survive to the present unlike that of the current mainstream Superman. He was also married to Lois Lane but she was killed. Superman was seemingly killed alongside Batman and Wonder Woman while fighting off an invasion from the planet Apokolips led by Steppenwolf. A supposedly resurrected Superman later appeared, having allied himself with Darseid's forces. He is defeated by the remaining heroes of this world. While he was dying, it was revealed he was not the actual Superman, who was still dead, but a Bizzaro-like creation.
|Bruce Wayne/Batman||Bruce was raised by his paternal uncle, Philip, following the murder of his parents. Along with his close friend Superman (Kal-L), Batman participated in the Justice Society and the war-time All-Star Squadron. Eventually, he retired and became the police commissioner of Gotham City. Wayne married Selina Kyle (Catwoman), and had a daughter named Helena Wayne, who became a costumed adventurer known as the Huntress. In 1979, he died battling the escaped-convict Bill Jensen (Adventure Comics #462), who had been granted powerful magical abilities by Fredric Vaux (Adventure Comics #463) as part of a failed plot to remove all superheroes, and memory of them, from the world. Although this Batman was retconned out of existence by the events of Crisis on Infinite Earths and All-Star Squadron #60, he was restored to continuity (still deceased) in JSA #85, as a result of the events of Infinite Crisis.
In the New 52, Batman is still married to Catwoman, and they have a daughter together, Helena Wayne, who became his sidekick, Robin. At some point, his wife, Selina was killed on action. Batman sacrifices himself alongside Superman and Wonder Woman against the invasion forces of Apokolips.
|Diana Prince Trevor/Wonder Woman||Diana/Wonder Woman||Princess Diana Trevor of Paradise Island, served as a member of the All-Star Squadron and soon after became secretary (later full-fledged member) of the Justice Society of America. As Diana Prince, she worked in the U.S. War Department as an assistant to intelligence officer Steve Trevor. Decades later, she and Trevor were married and had a daughter named Lyta, later known as Fury. Although Diana was retconned out of existence by the events of Crisis on Infinite Earths and All-Star Squadron #60, she was briefly restored to continuity in Infinite Crisis #5.
In the New 52, Wonder Woman is the last of the Amazons, and is violent and bitter as a result. Princess Diana is revealed to have a daughter, Fury, with whom she has a dysfactional relationship. She is killed by Steppenwolf in the battle for Earth with Apokolips, when she tries to buy time for Batman.
|Jay Garrick/The Flash||The Flash of Earth-Two is Jason Peter Garrick. As a college student, Garrick accidentally inhaled hard water vapors, (later stories would change this to heavy water vapors), after falling asleep in his laboratory where he had been smoking. As a result, he discovered that he can run at superhuman speed and had similarly fast reflexes. Decades later, Garrick became the first Justice Society member to learn of Earth-One's existence when he met his counterpart, Barry Allen.
In the New 52, a 21 year-old recent college graduate, Jay is spurned by his girlfriend, Joan, and possesses very little in terms of career prospects. He receives his "superspeed" from Mercury, a dying Olympian god who sees bravery in Jay, and is also the last god to fall following a war with Apokolips. He claims he has been held for the past 10 years by a greater threat than Apokolips. Jay escapes a World Army Helicopter that sees the event as Mercury dies and tells Jay to run. He saves a couple from Apokorats, saying he will do it in 'a Flash', the man then mentions he heard the hero say something.
|Alan Scott/Green Lantern||Green Lantern of Earth-Two is engineer Alan Scott. The source of Scott's power is the mystical "Starheart", the magical characteristics of the Earth-One universe gathered by the Guardians of the Universe. This collective force was hidden in the heart of a star and eventually became sentient. It helped to retard Scott's aging process. Scott marries the woman with the dual identity Rose and Thorn. The two have a pair of children who would grow up to become the superheroes Jade and Obsidian of the team Infinity, Inc.
In the New 52, Alan is the young dynamic head of GBC productions. Scott is revealed to have a boyfriend named Sam, to whom he intends to propose while on vacation in China. Before he can do so, however, the train on which the couple is travelling is suddenly wrecked. A mysterious green flame protects Scott and heals him; a disembodied voice informs him that the crash was caused by a force that threatens the whole world, and that Sam did not survive. The grief-stricken Scott is then told that he will be given the power to avenge his love and protect the world. The flame creates a costume for him, and molds Sam's engagement ring into a power ring with which Scott can harness his power. Reborn as the Green Lantern, Scott proceeds to help the other survivors and swears vengeance for Sam. Green Lantern is associated with The Green, a mystical realm/force that connects all plant life on Earth.
|Al Pratt/The Atom||The Atom of Earth-Two was college-student-turned-physicist Al Pratt. Pratt's tenure as the Atom was particularly notable, inasmuch as he was barely five feet (1.5 m) in height, and had no superpowers for much of his career. Through intense training, he achieved peak physical condition and became a fierce brawler. Among Golden Age members of the Justice Society, only Wildcat and Batman were considered more formidable in hand-to-hand combat.
In the New 52, Al is a U.S. Sergeant in charge of a squad carrying an atomic bomb meant to neutralize an Apokoliptian tower responsible for transporting Parademons to Earth. His squad however is attacked while en route to the tower and the bomb is detonated. Al is later found unharmed in the center of a giant hand print in the ground. Five years later, Al has become a captain in the World Army and is operating as a superhero codenamed "the Atom", possessing the atomic energy powers of his original counterpart and size-changing powers. Al is deployed as the Atom to take down Grundy who is rampaging across Washington DC. After dropping mid air from his transport, Al enlarges and lands on Grundy, ordering the Flash, Green Lantern and Hawkgirl to stand down.
|Wesley Dodds/Sandman||The Sandman was one of DC's early "Mystery Men," and DC has used the name for several different characters (See Sandman (DC Comics)). He was a member of the Justice Society. His schtick was to run around in a gasmask with a sleeping gas gun. Originally the character has no special abilities, but he was retroactively given the ability to have prophetic dreams. This tied him to DC's third version of the Sandman Dream (comics).
In the New 52, Dodds works for the World Army. In Washington DC is attacked by Solomon Grundy, Commander Wesley Dodds, along with his Sandmen paramilitary force, is sent to retrieve and save President Lightfoot. They are later assigned by Commander Khan in a special and unofficial mission to infiltrate Terry Sloane's secret facility, where confront and subdue a mind-controlled Michael Holt.
|Shiera Saunders Hall/Hawkgirl||Kendra Munoz-Saunders/Hawkgirl||Hawkgirl of Earth-Two was Shiera Saunders, companion of Carter Hall (Hawkman). Saunders and Hall were eventually married and had a son named Hector Hall, who became a costumed adventurer known as the Silver Scarab.
In the New 52, Kendra is a professional treasure hunter, and was hired by the World Army before an unrevealed event occurred in Egypt that resulted in the grafting of wings to Kendra's back, the same time Khalid Ben-Hassin found the Helmet of Fate. Her full origin has not been revealed other than some insinuation of her background as part of a secret program that included Al Pratt. She alongside the Flash, Green Lantern and Doctor Fate form the Wonders of the World.
|Kent Nelson/Nabu/Doctor Fate||Khalid Ben-Hassin/Doctor Fate||Doctor Fate was Kent Nelson, who was orphaned as a child after his archaeologist father was killed for opening the tomb of the wizard Nabu. The wizard raised Nelson and taught him the ways of magic, eventually giving him a mystical amulet and the Helmet of Fate, which contained Nabu's essence. Whenever Nelson wore the helmet, his personality melded with that of Nabu. Doctor Fate's Earth-One counterpart was the supervillain Doctor Chaos, who possessed a college research assistant named Burt Belker after acquiring a helmet containing a Lord of Chaos. He was soon confronted by Earth-One's teenage Superboy, who removed Belker's helmet and jettisoned it into space.
Khalid is an associate of Hawkgirl who discovers the Helmet of Nabu in a tomb in Egypt, but is reluctant to use its power due to the increasing presence of Nabu's spirit affecting his thoughts and sanity. After Superman mercilessly attacks him, Khalid becomes traumatized and psychologically damaged by the ordeal.
|Aquaman||Arthur Curry||Arthur Curry of Earth-Two was a member of the All-Star Squadron. He was retconned out of existence by the events of Crisis on Infinite Earths and All-Star Squadron #60 (the only visual differences from his Earth-One counterpart, initially, were yellow gloves instead of green, and yellow fins on the backs of his boots).|
|Black Canary||Dinah Drake Lance||The Black Canary of Earth-Two was Dinah Drake. One of the few female members of the Justice Society's World War II roster, she was mistakenly believed to have migrated to Earth-One to become a member of the Justice League of America. Eventually, it was revealed that Drake died from radiation poisoning, and that the Black Canary who journeyed to Earth-One was her daughter—Dinah Lance.2 Following the events of Crisis on Infinite Earths and All-Star Squadron #60, history records that Drake served as the original Black Canary, and that her daughter Dinah Lance succeeded her and joined the Justice League (with membership in the Justice Society to follow years later).|
|Catwoman||Selina Kyle||The Catwoman of Earth-Two was Selina Kyle. She was originally a criminal in Gotham City, and was initially one of the primary foes of Batman and Robin. Selina reformed in the 1950s (after the events of Batman #69) and married Bruce Wayne. Soon afterwards, the couple gave birth to their only child, Helena Wayne (the Huntress). Selina eventually died in 1976 after being blackmailed by a criminal into going into action again as Catwoman (as shown in DC Super-Stars #17). She was retconned out of existence by the events of Crisis on Infinite Earths and All-Star Squadron #60.|
|Commander Steel||Henry "Hank" Haywood||Commander Steel of Earth-Two was Hank Haywood, an injured marine whose body was rebuilt with mechanical components turning him into a cyborg hero with great strength and speed. A member of the All-Star Squadron, he immigrated to Earth-One and had an Earth-One counterpart in his own grandson, Henry Haywood III, who became a member of the Justice League of America. Post-crisis, another grandson, Nathan Haywood, joined the Justice Society as Citizen Steel.|
|Crimson Avenger||Lee Walter Travis||The Crimson Avenger of Earth-Two was wealthly newsman Lee Walter Travis. He and his partner Wing were among the first "mystery men", beginning their crimefighting careers in 1938. They were both members of the All-Star Squadron and the Seven Soldiers of Victory. Wing sacrificed his life to defeat the Nebula Man, while a terminally ill Crimson Avenger died piloting a ship away from the docks before it could explode (DC Comics Presents #38).|
|Green Arrow||Oliver Queen||Green Arrow of Earth-Two was a member of the All-Star Squadron and the Seven Soldiers of Victory. He died in 1985 during Crisis on Infinite Earths, and was retconned out of existence by the events of that series and All-Star Squadron #60.|
|Guardian||Jim Harper||The Guardian of Earth-Two was police officer Jim Harper. He was the uncle of Roy Harper, who was better known as Green Arrow's teen sidekick, Speedy. Decades later, Earth-One produced two counterparts: the first was another version of Jim Harper. The second was Mal Duncan, a nonpowered Teen Titan who discovered the original costume of the Earth-One Harper, and, with a strength-augmenting exoskeleton, briefly assumed the Guardian identity.|
|Harlequin||Molly Mayne||The Harlequin of Earth-Two is former criminal Molly Mayne. In 1948, Mayne betrayed her Injustice Society teammates in order to save the lives of the Justice Society. A subsequent deal with the U.S. government allowed her to work as an undercover agent for the FBI in return for amnesty for her past crimes. During the events of Crisis on Infinite Earths, Mayne and Alan Scott (Green Lantern) were married. The Harlequin of Earth-One is Duela Dent, a former Teen Titan who claimed to be the daughter of Batman villain Two-Face.|
|Hawkman||Carter Hall||Hawkman of Earth-Two was archaeologist Carter Hall. He and his companion Shiera Saunders (Hawkgirl) were eventually married and had a son named Hector Hall, who became a costumed adventurer known as the Silver Scarab.|
|Johnny Quick||Johnny Chambers||Johnny Quick of Earth-Two was a newsreel photographer who mastered the power of superspeed by reciting a mathematical formula: "3X2(9YZ)4A". During World War II, he was drafted into service as a member of the All-Star Squadron. While Johnny Quick had no counterpart on Earth-One, the Earth-Three version of the speedster was a supervillain and a member of the Crime Syndicate of America. The Johnny Quick who remains following Crisis on Infinite Earths is the one from Earth-Two, while the villain from Earth-Three was retconned as being from that anti-matter universe.|
|Johnny Thunder||Johnny Thunder||Johnny Thunder of Earth-Two—the seventh son of a seventh son—was born at 7 AM on the seventh day of the seventh month in 1917. As an infant, he was kidnapped by a group of men from the country of Badhnesia. He was given possession of the genie-like Thunderbolt during a mystic ritual performed on his seventh birthday. Thunder's Earth-One counterpart was a petty criminal who was capable of controlling the Thunderbolt (who apparently has no counterpart). The Johnny Thunder who remains following Crisis on Infinite Earths is the one from Earth-Two.|
|Manhunter||- Dan Richards

|During World War II, Earth-Two had two costumed vigilantes who assumed the name Manhunter: Dan Richards and Paul Kirk. Richards was a member of the Freedom Fighters, while Kirk joined the All-Star Squadron.|
|Plastic Man||Patrick "Eel" O'Brian||Plastic Man was a Quality Comics character, the rights to which were later acquired by DC Comics. Initially, DC stated that he hailed from Earth-X, along with all the Quality characters. Later, an Earth-One Plastic Man was introduced, and the original version was depicted as a native of Earth-Two who joined the All-Star Squadron during World War II and subsequently moved to Earth-X. The Earth-Two/Earth-X Plastic Man was retconned out of existence by the events of Crisis on Infinite Earths and All-Star Squadron #60.|

|Red Tornado||Abigail Mathilda "Ma" Hunkel||The original Red Tornado of Earth-Two is a widow known as "Ma" Hunkel. While her children were in their youth, Hunkel ran a small Manhattan grocery store. One of the first superhero parodies, her costume consisted of longjohns and a cooking pot which she wore on her head. Because of her roly-poly build, she was able to successfully masquerade as a man. Although a costume mishap prevented her from attending the first meeting of the Justice Society of America, she eventually became an honorary member. Many years later, an android calling himself the Red Tornado joined the Justice Society, but he eventually migrated to Earth-One and joined the Justice League of America.|

His allies included the All-Star Squadron along with Batwoman and Bat-Girl. He eventually became a member of the Justice Society of America. During his later years, he adopted a more Batman-like look for a time, and by the 1960s had become a lawyer and the ambassador to South Africa. He died in 1985 during Crisis on Infinite Earths, and was retconned out of existence by the events of that series and All-Star Squadron #60. This Robin's exploits were re-acknowledged in JSA Classified #4.|

An Earth 2 skin pack was released as downloadable content for Injustice: Gods Among Us. It included alternate skins for the Flash, Hawkgirl, and Solomon Grundy based on the appearances of Jay Garrick, Kendra Saunders and Grundy in New 52.
A pre-order skin pack for Batman: Arkham Origins video game will include two Earth 2 skins for Batman, both based on New 52: one depicting the original Batman, Bruce Wayne; the other depicting the new, black-and-red Batman.
- ^1 Jim Corrigan of Earth-Two was a murdered police detective who served as the human host for the Spectre. His Earth-One counterpart was a Metropolis police officer who often assisted Daily Planet cub reporter Jimmy Olsen and superhero Black Lightning.
- ^2 As Dinah Drake was about to die, Johnny Thunder's Thunderbolt transferred her memories into the mind of her daughter Dinah Lance—who had grown up in suspended animation in the Thunderbolt's magical dimension. After the memory transfer and Drake's death, the Earth-One Superman brought Lance to his world, where she joined the Justice League of America. Because the Thunderbolt erased the fact that Drake had a daughter from everyone's memory, Lance did not discover her true origin or identity until years later.
- ^3 During the 1970s and 1980s, the series The Brave and the Bold published a number of stories in which Wildcat teamed up with a character who appeared to be the Batman of Earth-One. In each of these stories, it was apparent that the two characters were from the same Earth. Since the JSA's Wildcat was clearly from Earth-Two, it was suggested that these stories took place on "Earth-B", in a reality separate from DC's mainstream continuity. Subsequent appearances in other titles verified that the Wildcat from The Brave and the Bold was indeed from Earth-One, and that his appearances in B&B took place on Earth-One as well.
- ^4 A number of villains had counterparts on Earth-One, including the Joker, the Penguin, Two-Face, the Toyman, the Prankster, Mr. Mxyzptlk, etc. Generally speaking, the older Earth-Two versions were phased-out or incorporated into their younger, Earth-One versions following Crisis on Infinite Earths.
