Earth Prime

Earth Prime (or Earth-Prime) is a term sometimes used in works of speculative fiction, most notably in DC Comics, involving parallel universes or a multiverse, and refers either to the universe containing "our" Earth, or to a parallel world with a bare minimum of divergence points from Earth as we know it — often the absence or near-absence of metahumans, or with their existence confined to fictional narratives like comics. The "Earth Prime" of a given fictional setting may or may not have an intrinsic value to or vital connection to the other Earths it exists alongside (although it appears to be the case that such Prime Earths — and sometimes the 'central universes' in which those Prime Earths exist as well — are portrayed in fiction to be vital to the existence of the other Earths).

PublisherDC Comics

In the DC Multiverse, Earth-Prime is the true Earth from which all the other worlds within the multiverse originate, the actual reality where the readers live, DC Comics operates as a publisher, and all superheroes are fictional. However, Earth Prime became an alternate reality in its first appearance in The Flash #179 (May, 1968), when the Flash accidentally travels there from Earth-One by being pushed by a creature called The Nok. The Flash, stranded, contacts DC Comics editor Julius Schwartz,[1] who helps him construct a cosmic treadmill to return to Earth-One. Eventually it was stated that the writers of DC Comics of Earth Prime subconsciously base their stories on the adventures of the heroes on Earth-One and Earth-Two.

In The Flash #228 (July/Aug 1974),[2] Earth Prime's Cary Bates travels to Earth-One, where he discovers that the stories he writes are not only based on events on Earth-One, but can actually influence these events as well. This power turns for the worse in Justice League of America #123 (October 1975),[3] when Bates is accidentally transported to Earth-Two. The interdimensional trip temporarily turns Bates into a supervillain, and he quickly kills the Justice Society of America. Luckily fellow DC writer Elliot S. Maggin, with the help of the Justice League and the Spectre, is able to restore matters on both Earths in Justice League of America #124 (November 1975).[4]


The first superhero is Ultraa, introduced in Justice League of America #153. Like Superman, Ultraa was the sole survivor of a destroyed alien world, rocketed to Earth-Prime as a baby. After his first encounter with the Justice League, Ultraa decided Earth-Prime was not ready for superheroes and relocated to Earth-One. Post-Crisis, when there was no longer an Earth-Prime or greater multiverse, Ultraa was retconned into being from the planet Almerac, homeworld of Maxima.


The second superhero (later villain) is Superboy-Prime, the true Superman from which all the other Supermen originate. He first appeared in DC Comics Presents #87 (Nov. 1985). This Superboy's powers first manifested around the time of the passage of Halley's Comet in 1985. Just after manifesting his powers, Superboy-Prime met Earth-One's Superman. Very soon thereafter Earth-Prime was destroyed in Crisis on Infinite Earths #10. Superboy-Prime escaped his universe's destruction, and later joined Earth-Two's Superman, Earth-Two's Lois Lane-Kent, and Earth-Three's Alexander Luthor in a "paradise dimension".

Superboy Prime possesses powers far exceeding those of the modern "New-Earth" Superman (Kal-El).

In issue #6 of the Infinite Crisis mini-series, a now anti-heroic Superboy-Prime convinced Alexander Luthor that Earth-Prime was the ideal world and urged him to draw his inspiration for making a new Earth from Earth-Prime. Luthor began searching through the myriad Earths for Earth-Prime and, in a metatextual nod to Earth Prime's original status as the keystone Earth, looks directly at the readers and reaches out towards them to grab our reality.

In 2004, DC revisited the Earth-Prime concept in the miniseries Superman: Secret Identity. Writer Kurt Busiek states in the introduction to the collected volume of the series that the original appearance of Superboy-Prime was the inspiration for his graphic novel.

Legion of Super-Heroes

In 2008 the Final Crisis tie in series Legion of Three Worlds, makes various references to Earth-Prime, while Superboy-Prime is still looking to make his "Perfect Earth". He starts by rebuilding the Legion of Super-Villains to fight Superman and the three versions of the Legion of Super-Heroes. During the battle, the 2004 team's Element Lad created Kryptonite that unexpectedly affected Superboy-Prime. The Kryptonite of New Earth had no effect on Superman (Kal-L) and Prime during Infinite Crisis.

At the end of the mini series, it's revealed that Earth-Prime has been reborn and Superboy-Prime was returned there. It was also revealed that the Threeboot Legion are from Earth-Prime's future. The current status of Superboy-Prime after the events of Flashpoint remains unclear, but he has not reappeared since 2011. The character may have been obliterated by the continuity change and shifts within the multiverse that occurred after that core DC event.

The Multiversity: Ultra Comics and Earth-33

In September 2011, The New 52 rebooted DC's continuity. In this new timeline, Earth-33 is introduced in Grant Morrison's The Multiversity series, as the additional designation for Earth-Prime. This Earth continues the tradition of having minimal superhero activity – in this case, the minds of Earth-33's comic book readers have empowered a superhero named Ultra Comics. Ultra is the only metahuman on that world, fighting the encroachment of the "Gentry" (the series' lead villains) by confining their presence on 'our' world to the pages of an 'entrapment' comic book built around the title character.

Marvel Comics

In the fictional Marvel Universe, the 'Earth Prime' of that setting is designated by extradimensional cartographers as Earth-1218,[5] where real-life readers buy Marvel Comics. On some occasions, various characters of the Marvel Universe, looking for their version of God, encounter 'real world' figures such as Jack Kirby and Stan Lee. Yet other characters (such as She-Hulk and Deadpool) are capable of breaking the fourth wall, addressing the readers directly. Still others, such as the Earth's Watcher, Uatu, is possessed of the ability to see all alternate Earths in the Marvel Universe setting at will, including the real one in which he and all other beings are nothing more than fictional characters (in some early issues of What If?, the Watcher actually addressed the reader by showing him which issues of which comics the past exploits of a given character could be found in). Having a similar name, "Prime Earth" is the new designation of "Earth-616".[6]


Earth Prime, as used in the television show Sliders, is the name of the alternate Earth where the four original sliders (Quinn Mallory, Wade Welles, Rembrandt Brown, and Maximillian Arturo) started their journey. This Earth was the same as ours until 1997 or 1998, when the Kromaggs slid onto Earth Prime and conquered it.

The Dark Tower

Much of the action in the last few books of Stephen King's Dark Tower series takes place in "the keystone world", essentially the Earth Prime concept under a different name, complete with appearances by King himself as a character.

The Chronicles of Amber

Though not using the term "Earth Prime", Roger Zelazny's The Chronicles of Amber fantasy series features a similar concept. In the Amber stories, Amber is the only true world; all others, including our Earth, are but "shadows" of the tension between it and Chaos.

Teenage Mutant Ninja Turtles

In the Teenage Mutant Ninja Turtles made-for-TV film, Turtles Forever, Ch'rell (or 2003 series's version of The Shredder), took the technodrome from his 1987 series counterpart and Krang and upgraded it with Utrom technology. He later decided to destroy Turtle-Prime to destroy the multiverse. He was stopped by the three teams of turtles from the Prime, 1987, and 2003 universes. Although the true "Earth Prime" of the movie would be that inhabited by Kevin Eastman and Peter Laird in the closing shot, shown putting the finishing touches on the first issue of the Teenage Mutant Ninja Turtles comic book.

In other media

  • In the DC animated feature Justice League: Crisis on Two Earths, the villainous Owlman's ultimate goal is to locate a universe that he designates as Earth Prime, the so-called "original" universe that all other universes stem from, and destroy it, thus leading to the destruction of all reality as well, due to believing that the existence of a multiverse meant nothing truly matters. Earth Prime is shown to be a desolate barren wasteland of a planet which has been ripped out of orbit, with ruins as far as the eye can see. It is unknown what exactly caused its desolation, though Owlman reasons that mankind was destroyed by itself.
  • In the final episode of Spider-Man: The Animated Series, after saving the multiverse from Spider-Carnage, an evil version of himself from an alternate Earth, Spider-Man briefly visits Earth Prime and meets his own creator, Stan Lee.

Bushido is a fictional character, a DC Comics superhero who was a short-lived member of the Teen Titans.

Crime Syndicate of America

The Crime Syndicate are teams of fictional supervillains from one of DC Comics' parallel universes where they are the evil counterparts of the Justice League. The original team was specifically known as Crime Syndicate of America and is sometimes abbreviated as CSA. This first superpowered Crime Syndicate team appeared in Justice League of America (vol. 1) #29 in August 1964. The primary successive incarnation, known as the Crime Syndicate of Amerika (with the variant spelling of America), first appeared in the 2000 JLA: Earth 2 graphic novel.

A related successive group on Earth-3 is known as the Crime Society of America and first appeared in 52 #52, and later featured in Countdown to Final Crisis. A "Golden Age" supervillain group, the Crime Society was to Earth-2 what the Anti-Matter Crime Syndicate of Amerika was to Earth-0, until it was removed from continuity following DC's 2011 Flashpoint storyline and The New 52 company-wide reboot. Following this, a singular Crime Syndicate is the Earth-3 counterpart of the Earth-0 Justice League, first appearing in Justice League #23 (October 2013), and the main focus of the company-wide crossover storyline Forever Evil. The events of that story have far-reaching consequences in the DC Universe, and the Crime Syndicate characters which survive remain on Earth-0 in one form or another after its events.

Crisis (DC Comics)

A crisis in the DC Universe is an event with potentially great consequences, often involving multiple universes and sometimes even threatening their existence.From 1963 to 1985 the term "Crisis" was used to describe the annual events in which the Justice League of America of Earth-One and the Justice Society of America of Earth-Two met and worked together, usually in an incident involving one or more of the parallel worlds of the DC Multiverse. This usage culminated in 1985's year-long Crisis on Infinite Earths, a companywide crossover in which the Multiverse was eliminated. After several years of disuse, the term "crisis" was applied to several events with either "universal" stakes or substantial character consequences, such as Zero Hour: Crisis in Time, Identity Crisis, Infinite Crisis, and Final Crisis.In the two decades after 1985, "Crisis" by itself came to refer specifically to Crisis on Infinite Earths, especially when used in house pre-Crisis and post-Crisis.

Characters in the DC Universe sometimes use the term "Crisis" in the same sense, referring either to any great threat, or as "the Crisis" in reference to the events of Crisis on Infinite Earths, either as they happened or as they were commonly remembered in the revised history after the fact.

With the publication of Infinite Crisis, and Final Crisis, the use of the term within the DC Universe has shifted. The Crisis on Infinite Earths is sometimes referred to as "the First Crisis". The Infinite Crisis has occasionally been referred to as simply "the Crisis", and a character from the 31st century called it "the Middle Crisis" DC did not call other important events such as Forever Evil or Convergence a "Crisis", even explicitly stating that some, such as Doomsday Clock, are not "Crisis" events.

DC Universe

The DC Universe (DCU) is the fictional shared universe where most stories in American comic book titles published by DC Comics take place. DC superheroes such as Superman, Batman, and Wonder Woman are from this universe, and it also contains well known supervillains such as Lex Luthor, the Joker, and Darkseid. In context, the term "DC Universe" usually refers to the main DC continuity.

The term "DC Multiverse" refers to the collection of all continuities within DC Comics publications. Within the Multiverse, the main DC Universe has gone by many names, but in recent years has been referred to by "Prime Earth" (not to be confused with "Earth Prime") or "Earth 0".

The main DC Universe, as well as the alternate realities related to it, began as the first shared universe in comic books and were quickly adapted to other media such as film serials or radio dramas. In subsequent decades, the continuity between all of these media became increasingly complex with certain storylines and events designed to simplify or streamline the more confusing aspects of characters' histories.


In the fictional Marvel Comics multiverse, Earth-616 is the primary continuity in which most Marvel Comics titles take place.

Legion Flight Ring

A Legion Flight Ring is a fictional object featured in comic book titles published by DC Comics. It first appeared in Adventure Comics #329 (February, 1965) used by the Legion of Super-Heroes.

List of Sliders characters

Sliders is science fiction television show that aired on the Fox network for three seasons and the Sci Fi Channel for two seasons. The show starred Jerry O'Connell as Quinn Mallory, a college student who builds a device that can transport himself and others to parallel worlds. Due to the nature of the show's similar (yet always slightly different) worlds conceit, several actors appear as different versions of the same character. The following is a list of actors who have appeared on Sliders.

List of Sliders episodes

The following is a list of episodes for the Fox and Sci Fi Channel original series, Sliders. The series aired on Fox from March 1995 to May 1997 and on the Sci Fi Channel from June 1998 to February 2000. A total of 88 episodes were produced.

Marvel Universe

The Marvel Universe is a fictional universe where the stories in most American comic book titles and other media published by Marvel Comics take place. Super-teams such as the Avengers, the X-Men, the Fantastic Four, the Guardians of the Galaxy, the Defenders, the Inhumans and other Marvel superheroes live in this universe, including characters such as Spider-Man, Iron Man, Thor, the Hulk, Captain America, Daredevil, Wolverine, Black Panther, Doctor Strange, Blade, Ghost Rider, the Punisher, Deadpool, Silver Surfer, and numerous others.

The Marvel Universe is further depicted as existing within a "multiverse" consisting of thousands of separate universes, all of which are the creations of Marvel Comics and all of which are, in a sense, "Marvel universes". In this context, "Marvel Universe" is taken to refer to the mainstream Marvel continuity, which is known as Earth-616 or currently as Earth Prime.

Owlman (comics)

Owlman is the name of several fictional characters who appear in comic books published by DC Comics. The characters are villainous alternate-universe counterparts of Batman.


Sliders is an American science fiction and fantasy television series created by Robert K. Weiss and Tracy Tormé. It was broadcast for five seasons between 1995 and 2000. The series follows a group of travelers as they use a wormhole to "slide" between different parallel universes. Tormé, Weiss, Leslie Belzberg, John Landis, David Peckinpah, Bill Dial and Alan Barnette served as executive producers at different times of the production. For its first two seasons it was produced in Vancouver, British Columbia. It was filmed primarily in Los Angeles, California in the last three seasons.

Since its debut on March 22, 1995, the first three seasons were broadcast by the Fox network. After being canceled by Fox, the series moved to Sci Fi Channel for its final two seasons. The last new episode first aired on December 29, 1999 in the United Kingdom, and was broadcast on the Sci Fi Channel on February 4, 2000.


Superboy-Prime (Clark Kent, born Kal-El), also known as Superman-Prime or simply Prime, is a DC Comics superhero turned supervillain, and an alternate version of Superman. The character first appeared in DC Comics Presents #87 (November 1985), and was created by Elliot S! Maggin and Curt Swan (based upon the original Superboy character by Jerry Siegel and Joe Shuster).

Superboy-Prime is from a parallel Earth called Earth-Prime that had no super-heroes. There, Superman and the other comic superheroes were fictional characters only seen in comic books. The Earth-Prime universe was erased during the Crisis on Infinite Earths, and Superboy-Prime ended up in a "paradise" dimension where during that time, he found himself unable to let go of his former life and destiny as Earth's greatest hero.

Over time, his convictions and morals become twisted and warped, and he came to believe that Earth-Prime is the only proper Earth and that Superboy-Prime was the only one worthy of the Superboy mantle. Prime firmly believes that being Superman is his calling despite the fact that he has become a psychotic and murderous villain. His overwhelming strength, speed, and ruthlessness make him one of the most dangerous foes in the DC Universe.

The name "Superman-Prime" was first used by Grant Morrison in DC One Million (1998) for the mainstream Superman in the 853rd century (he is essentially the same Superman from the All-Star Superman storyline). Earth-Prime's Superboy first refers to himself as "Superboy-Prime" in Infinite Crisis #2 (January 2006).

Superboy and the Legion

"Superboy and the Legion" is a story arc that was published by DC Comics, and presented in Teen Titans vol. 3, #16, and Teen Titans/Legion Special (Late November 2004). It was written by Geoff Johns and Mark Waid, with pencils by Mark McKone, Ivan Reis, and Joe Prado. It is the final story arc in the Post-Zero Hour continuity of the Legion of Super-Heroes.

The Rowan

The Rowan (1990) is a science fiction novel by American writer Anne McCaffrey, the first book in "The Tower and the Hive" series (also known as "The Rowan" series). It is set in the universe of the "Pegasus" trilogy, against a backdrop of a technologically advanced society in which telepathy, psychokinesis and other psychic Talents have become scientifically accepted and researched. Telekinetic and telepathic powers are used to communicate and teleport spaceships through space, thus avoiding the light barrier and allowing for the colonization of other planetary systems.

In the series, psionic powers occur of varying strength, the possessors being ranked from T12 (the weakest) to T1 (the strongest). The very strongest are employed as "T1 Primes" by an independent company, FT&T, (Federated Telepaths and Teleporters) for teleporting cargo and passengers between the systems.

Titan (DC Comics location)

Titan is one of the moons of the planet Saturn. In the 30th and 31st centuries of the DC Comics Universe the moon is inhabited by a colony of telepaths.
