Krypton is a fictional planet in the DC Comics universe. No longer in existence, it is the native world of the superheroes Superman and Supergirl.

Named after the chemical element krypton, the planet was created by Superman creators Jerry Siegel and Joe Shuster, and was first referred to in Action Comics #1 (June 1938); the planet was given its first full-fledged appearance in Superman (volume 1) #1 (1939).

Krypton exploded as a result of highly unstable geological conditions. As originally depicted, the entire civilization and race of Krypton perished in the explosion, except for one survivor: the baby Kal-El, who was placed in an escape rocket by his father Jor-El and sent to the planet Earth. Kal-El grew up to become Superman. In some versions of the myth, a few additional survivors, such as Krypto, Supergirl and the criminal inhabitants of the Phantom Zone, were also survivors of the cataclysm.

Versions of Krypton

Golden Age Krypton

History
In its first appearance, Krypton was only depicted at the moment of its destruction, the nature of life on Krypton being unaddressed and frankly irrelevant to Superman's adventures on contemporary Earth; the plain fact of his extraterrestrial origin was considered sufficient enough to explain his superpowered status. Soon, beginning in the Superman comic strip, Krypton was shown to have been an evolved version of Earth, older by eons and possessed of all the beneficial progress that implied (though the downside was the hint that Krypton exploded due mainly to old age). Kryptonians, though otherwise completely human, were superior both intellectually and physically to natives of Earth (further, Krypton had much heavier gravity, making them all stronger as well). They lived under the rulership of a scientific elite, in cities of delicate art-deco towers and wore costumes in the style of Alex Raymond characters. The trappings of Krypton were all rather reminiscent of the final technological utopia depicted in the H.G. Wells film Things to Come. The debut of the Superman comic strip in 1939 also delved into further details about Krypton, including introducing the idea that all Kryptonians possessed a minimal level of heightened physical abilities, including superstrength and superspeed. In the early comics' version of Krypton, Superman's parents were named "Jor-L" and "Lora" (changed to the more familiar "Jor-El" and "Lara" by the end of the 1940s).

The Golden Age Krypton would be revised into another form almost as soon as it was defined (see Krypton in Transition below), and very few stories were written about it. However, after the introduction of DC's multiverse in the 1960s, this version of Krypton was declared to be the Krypton of the Earth-Two universe (the native dimension of DC's Golden Age characters) and its Superman. This was especially so in the late-1970s run of All-Star Comics, where Power Girl, the Earth-Two version of Supergirl, was introduced.

In the Golden Age, Superman was unaware initially of his true origins; in Superman (volume 1) #61, Superman discovered the existence of Krypton for the first time and learned of his Kryptonian heritage.

Golden Age Krypton was retroactively labeled Krypton-Two after the creation of Earth-Two and the Multiverse.

Krypton in transition
Over the course of the 1940s and 1950s, various alterations and additions to the makeup of Krypton were made in the comics. Among them was explaining why the natives of Krypton perished if they had possessed superpowers on their native world (as was the case in the earliest versions of Krypton outlined above, although this only became a problem once Superman—and by extension anyone from Krypton—was portrayed as increasingly powerful and able to withstand nuclear explosions, contrasted with his original power level in which a bursting mortar shell could penetrate his skin). Thus, it was explained by the early 1950s that Kryptonians were powerless on their own planet, and would only gain superpowers within a lower gravity environment. In the early 1960s, added to this was the need to be exposed to the rays of a yellow sun (versus Krypton's red sun) to gain superpowers, with the yellow sun aspect soon gaining the much greater emphasis. Other changes to the concept of Krypton and its culture were introduced, many of which were stylistic.

Silver Age Krypton

By the late 1950s, Krypton played an increasingly larger role in various Superman stories, with greater amounts of details given to Krypton's makeup.

History
In the Silver Age version of Krypton, Kryptonians made use of their advanced science to create a world where scientific inventions and research influenced much of daily life. Robots and computers were used for many tasks on Krypton, even for determining what career paths young boys and girls would take as they grew up. Scientific and technological research was highly valued on Krypton, with the ruling body of Krypton named the "Science Council."

Several stories featured characters travelling back in time to visit Krypton before its destruction; the most well known of these is probably the 1960 story "Superman's Return to Krypton," in which Superman is swept back in time to Krypton some years before its destruction. Powerless, he spends some time on the planet, where he meets his future parents-to-be and falls in love with a Kryptonian actress named Lyla Lerrol.

Superman's Kryptonian heritage was a frequent factor in Silver Age Superman comic storylines, as he was fully aware of his origins from an early age. Superman would use this knowledge for such tasks as constructing robots or observing some of Krypton's traditions.

The terrain of this Krypton was bright and vivid, featuring such landmarks as the Scarlet Jungle, Gold Volcano and the Jewel Mountains. The Scarlet Jungle in particular contained many strange beasts and plants, such as a species of giant mole that could eat through metal. There were two consecutive capital cities on Krypton: Kandor and Kryptonopolis. The city of Kandor was shrunk by the evil android Brainiac and taken away; Kryptonopolis became the new capital of Krypton. In his first encounter with Brainiac, Superman discovered the city of Kandor preserved in a bottle. He rescued it and took it to Earth with him, vowing to someday discover a way to return the city to normal size. In the late 1970s, Kandor was enlarged, and its inhabitants left Earth to settle on a new planet named Rokyn.

Krypton had two moons, but one of them was accidentally destroyed by the Kryptonian scientist Jax-Ur when he was experimenting with space travel. The disaster killed millions of inhabitants of the moon, and because of this, Jax-Ur became the first criminal to be banished to the Phantom Zone, which had been discovered by Jor-El. This disaster also prompted the Science Council of Krypton to ban space flight completely, providing another explanation of why Krypton's civilization perished with the planet.

Destruction
Krypton exploded due to a build-up of internal pressures in its uranium core. The explosion transformed most of the matter which made up the planet into a radioactive material that became known as kryptonite, which would have various (generally adverse) effects on the few survivors of Krypton in ensuing years.

Survivors
The Silver Age Superman was not alone in the survival of Krypton's destruction, being joined by his cousin Supergirl, the Phantom Zone criminals, Beppo the super-monkey, Krypto the superdog, a juvenile delinquent named Dev-Em and the entire population of the city of Kandor.

When the planet exploded, one entire city of Krypton survived the cataclysm. This city, named Argo City, drifted through space on an asteroid-sized fragment of Krypton, which had been transformed into kryptonite by the explosion. The super-advanced technology of its Kryptonian inhabitants gave the denizens of Argo City the ability to construct a life-sustaining dome that allowed them to survive for several years, in addition to building a lead shield that protected their city from the kryptonite radiation of their asteroid. However, the protective shield was destroyed in a meteor storm, exposing the inhabitants to the deadly radiation. One sole survivor of Argo City, Kara Zor-El, was sent to Earth by her scientist father to live with her cousin Kal-El, who had become known as Superman. Kara adjusted to her new life on Earth and became known as Supergirl.

In 1979, a miniseries entitled World of Krypton was published, providing a great amount of detail into Krypton's history just before its destruction, along with the life story of Jor-El himself. In the 1980s, writer Alan Moore gave a somewhat darker glimpse into the world of Krypton in his story "For The Man Who Has Everything" (in Superman Annual #11).

A three-issue mini-series entitled The Krypton Chronicles, published in 1981, tells of Superman researching his roots when as Clark Kent he was assigned to write an article about Superman's family by an assignment editor impressed with the television mini-series Roots. To do so he and Supergirl travel to Kandor where they learn the history of the El family.

The race of Krypton was believed by some to be linked to the alien world of Daxam, a planet whose inhabitants also had powers and abilities similar to Superman's when they were exposed to the radiation of a yellow sun. However, the Daxamites, as they were known, were highly susceptible to lead poisoning, which affected them in a manner similar to kryptonite when they came into contact with lead. One Daxamite, Mon-El, was a member of the Legion of Super-Heroes in the 30th century. In this version, the Daxamites were originally Kryptonians who left their homeworld in order to explore the Universe. The Eradicator, programmed to preserve all Kryptonian culture, altered the birthing matrices ("artificial wombs") the explorers took with them so that the newborns would be fatally vulnerable to lead. Thus, if they persisted in their anti-Kryptonian wanderlust, they would all die from it.

Crisis on Infinite Earths
After the 1985 miniseries Crisis on Infinite Earths, this version of Krypton was soon replaced by a newer version. However, the Silver Age Krypton made a rare post-Crisis appearance in The Sandman #48, during a flashback sequence featuring Death and Destruction of The Endless, beings who were evidently unaffected by the reality-altering events of the Crisis.

Modern Krypton

The Man of Steel
Following Crisis on Infinite Earths, which “rebooted” the history of the DC Universe and retroactively eliminated the existence of the Golden and Silver Age versions of Krypton, writer and artist John Byrne was given the task of recreating the entire Superman mythos. This rewrite was started in the 1986 Man of Steel miniseries, which addressed Krypton in both its opening and closing chapters. Krypton itself was the main subject of the late 1980s The World of Krypton miniseries (not to be confused with the 1979 miniseries of the same name). This miniseries was written by Byrne and illustrated by Mike Mignola, and filled in much of Krypton's new history.

=History
= The new Krypton was approximately the size of Earth and orbited the red sun Rao, located fifty light-years from our solar system. Over 100,000 years ago, Krypton had already developed scientific advancements far beyond those of present-day Earth, and by a few millennia past had conquered disease, learned to retard the aging process and perfected cloning; vast banks of non-sentient clones held multiple copies of each living Kryptonian so that replacement parts were always available in the case of injury. All Kryptonians were effectively immortal and eternally young, and enjoyed an idyllic and sensual existence in an arcadian paradise. However, this society was tipping towards decadence and eventually political strife resulted from the debate as to whether clones should have rights (sparked by the presence of an alien missionary). Eventually this disagreement led to open violent conflict, during which Kryptonian science was turned to warfare and several superweapons were developed and used. Among them were the devices which became known as the Eradicator and the Destroyer. Although the Eradicator's effects (altering the DNA of all Kryptonian lifeforms so that they would instantly die upon leaving the planet) were felt immediately, the Destroyer's effects were possibly more significant: by the time the Kryptonian government conceded defeat and abolished the clone banks, a terrorist faction known as Black Zero had started the Destroyer, a device intended to trigger a massively explosive chain reaction in the planet's core. At the time, it was believed that the device had been stopped before it could achieve this, but eventually it was discovered, centuries later by Jor-El, that the reaction had only been slowed to a nearly imperceptible rate and would eventually destroy the planet as intended.

=The Destruction of Krypton
= In the meantime, though it had for now survived the war, Krypton was scarred deeply by it. The formerly lush garden world was burned and blasted, left mostly a lifeless desert. In direct contrast to the society that had existed prior to the Clone Wars, a sterile and emotionally dead civilization emerged. The population became isolated from one another, living in widely separated technological citadels and shunning all personal contact. Procreation became a matter of selecting compatible genetic material which would then be placed within an artificial womb called a "birthing matrix". Any attempt to contact other worlds was forbidden, and the planetary government maintained an isolationist stance forbidding space exploration of any kind. It was into this world that the young scientist Jor-El was born. By his adult years, the mysterious “Green Plague” was killing Kryptonians by the hundreds, and upon researching the matter Jor-El discovered that the cause was growing radiation produced by the planet's increasingly unstable core. Due to this process the planet itself was going to explode. Unable to convince his associates to abandon tradition and consider escape, Jor-El took the birthing matrix of his unborn son Kal-El, removed the Eradicator's planetary binding and attached a prototype interstellar propulsion system to the vessel. Just as the planet began to shake apart, he launched the matrix towards Earth, where it would open and give birth to the infant upon landing (The post-Crisis Superman therefore was technically "born" on Earth).

=The Last Son of Krypton
= A central theme of this version of the Superman mythos was that the character was to remain the last surviving remnant of Krypton. Thus, Silver Age elements such as Supergirl, Krypto and Kandor had never existed in this version (though post-Crisis versions of these elements were eventually reintroduced). The supervillain Doomsday was revealed in the 1990s as a being genetically enhanced by a mad scientist on a distant planet later known as Krypton, this happened hundreds of thousands of years before the rise of the original Krypton's civilization, (this fact explains how Kryptonians obtained their advanced technology). In the newer continuity, Superman also only became aware of his alien heritage sometime after his debut as a superhero, when a holographic program encoded into the vessel which brought him to Earth uploaded the information into his brain.

=Revisiting Krypton
= In a late 1980s storyline, Superman traveled to the former site of Krypton, to discover that the planet was slowly reforming from the vast sphere of debris remaining. However, it would take millions of years before the planet would be solid again.

In the 1990s comic series Starman, Jack Knight became lost in time and space and landed on Krypton several years before its destruction, and met Jor-El as a young man. The story boldly implies that it was this early meeting with a Terran that led Jor-El to study other worlds, and eventually choose Earth as the target for his son's vessel.

In an early 2000s storyline, an artificial version of the pre-Crisis Krypton was created in the Phantom Zone by Brainiac-13, a descendant of the original Brainiac who had traveled back in time to the present. It was stated to have been based on Jor-El's favorite Kryptonian historical period.

Superman: Birthright
In the 2004 comic miniseries Birthright, a new retelling of Superman's origin and early years, Mark Waid depicted a Krypton with elements of various versions of Krypton, but was closer to the pre-Crisis version. It was later implied that the time-bending adventure in Superman (2nd series) #200 had rewritten history so this was now the "official" version, and later stories have held to Birthright as being the official current version of Superman's origin.

Waid also made use of Superman's "S"-shield symbol in his version of Krypton. While in previous comic versions of the mythos, the "S" simply stood for "Superman," in Birthright, Waid presented the symbol as a Kryptonian symbol of hope (borrowing and modifying a concept from The Movie). DC's mandate for Superman being Krypton's only survivor changed as well. Birthright heralded the return of Krypto, Kandor, and Kara Zor-El as Supergirl.

The series reversed a lot of Byrne's decisions from The Man of Steel to reflect the more Silver Age-oriented version of Superman, similar to the Smallville and Superman movies.

Other media

Radio

The first non-comics version of Krypton was presented in the debut storyline of the 1940s Superman radio series. In the radio show, Krypton was part of the Solar System, a Counter-Earth sharing Earth's orbit but on the opposite side of the Sun.

Animation

Krypton was very briefly depicted in the first Fleischer Studios-produced Superman cartoon in the early 1940s as "a planet that burned like a green star in the distant heavens where civilization was far advanced and it brought forth a race of Supermen whose mental and physical powers were developed to the absolute peak of human perfection," implying that all Kryptonians had Superman's abilities even on their own planet. The planet is seen only from a distance.

Depictions of Krypton on both The New Adventures of Superman and Super Friends are generally similar to those of the pre-Crisis comic books.

In The Animated Series, a pilot episode (later recut as a 3-part episode) depicts Krypton as being basically similar to the pre-Crisis version (it was scientifically advanced, Kal-El appeared to be about two-years-old as in the Silver Age comics, there are depictions of peculiar animals) although with elements of the Man of Steel version (such as the appearance of the characters' wardrobe). Krypton's climate is shown to have both temperate and Arctic conditions. According to commentary on the DVD collection for the show's first season, part of Krypton's appearance was influenced by the artistic style of American comic book artist Jack Kirby.

This version depicted the android villain Brainiac indirectly destroying Krypton through a massive sin of omission (and even deception), as the caretaking program for the planet. Later episodes have dealt with this issue.

Superman: The Movie

With the release of the first feature-length Superman movie in 1978, a vastly less idyllic image of Krypton, compared to the previous comics' versions, was presented. Whereas in the comics, Krypton was colorful and bright, onscreen it was envisioned as a stark white terrain of jagged frozen plateaus, stretching broadly under heavy dark skies. The Kryptonians themselves were portrayed as being coolly cerebral, clad in stark white and treading halls of jet black under crystalline arches. The crystalline motif was employed not only in the archecture, but in the landscape and technology as well, suggesting that the entire planet had been adapted and altered by Kryptonian influence. The planet was ultimately destroyed when its star began to collapse; the planet was pulled into the sun and ripped apart, then incinerated when the star went nova.

This version of Krypton was to have a strong influence on John Byrne's 1986 reimagining of the world. However, this Krypton was still presented as having a society "better" than Earth's, unlike the Krypton that Byrne envisioned. For instance, there was no death penalty on Krypton because almost all criminals were rehabilitated (the ones that were not were banished to the Phantom Zone). Superman himself thought very highly of the planet and was proud to have come from there. Also, in this version of the story, both Jor-El and Lara preserve some part of their essence on the ship that brings their child to Earth, so that on Clark Kent's eighteenth birthday, Jor-El appears to him and initiates twelve years of Kryptonian education for the youth.

The origin of Superman's symbol is given a Kryptonian origin here (as Birthright would years later). Male Kryptonians wear some sort of symbol on their chests, assumed to be a family crest by some; Jor-El and Superman after him wear the familiar S-shield, which Lois Lane later assumes to be the S from the alphabet.

Lois & Clark

This version of Krypton was somewhat similar to the version on Superman: The Movie. Highly advanced technology, but this version's Kryptonians are more loving than the Man of Steel version.

Smallville

The 2000s television series Smallville presents a version of Krypton that borrows elements from the 1978 movie version of the planet.

Superman Returns

The 2006 movie Superman Returns presents a version of Krypton almost identical to Superman: The Movie (since Superman Returns is set in the same continuity as the first movie). In the beginning of the film, scientists discover the remains of Krypton. Superman leaves earth for five years to look for it. His ship is seen leaving the dead planet. During the beginning, we see the city where Kal-El was born (including the famous white dome that housed the trial of General Zod, Ursa, and Non), then as to replicate the liftoff, other cities can be seen on the night side (including Argo City, setting up the scene for Supergirl, and then finally the planet's destruction by a supernova of its red supergiant sun, similar to the supernova destructions seen in Generations.

Superman Returns extends the crystalline Kryptonian technology from Superman: The Movie which allowed young Clark Kent to "grow" the Fortress of Solitude. In the new movie, Kryptonian crystals are able to grow huge landmasses, and incorporate the properties of the surrounding environment. Growing land in this manner causes widespread power failure in the vicinity.

addendum: Science Fiction author Larry Niven speculates Krypton was a dwarf star orbiting a red supergiant. Although he does not specifically state it, his (non-canon) articles imply Krypton may have been a late-stage colony world, allowing for the possibility of other Kryptonians.
