===Krypton in the
Golden Age of Comic Books===
History . In its first appearance, Krypton was only depicted at the moment of its destruction. Beginning in the
Superman comic strip, Krypton was shown to have been a planet similar to Earth, only older by eons and possessed of all the progress that implied. It is suggested that Krypton exploded due mainly to old age and the massive use of electricity Kryptonians used for their technology. The debut of the
Superman newspaper comic strip in 1939 delved into further details about Krypton, introducing the idea that all Kryptonians possessed a level of heightened physical abilities, including
superhuman strength and speed. In the early comics' version of Krypton,
Superman's parents were named Jor-L and Lora, though their names were changed to the more familiar
Jor-El and
Lara by the end of the 1940s. 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.
Power Girl (Kara Zor-El) was introduced as the Earth-Two version of
Supergirl in 1976.
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 an explanation of why the natives of Krypton were killed if they had possessed superpowers on their native world. Thus, it was explained by the early 1950s that Kryptonians were powerless on their own planet and would gain superpowers only within a lower
gravity environment. This matched contemporary theories that humans would be able to lift greater masses and leap greater distances on the
Moon than on Earth due to its lesser gravity. In the early 1960s, it was explained that Kryptonians derived their powers from the light of a yellow
sun. Under a
red sun such as that of Krypton, Kryptonians have no powers. ===Krypton in the
Silver Age of Comic Books=== By the late 1950s, Krypton played an increasing role in various
Superman stories, with greater detail provided about Krypton's makeup. 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 advanced Kryptonian technology or observing some of Krypton's traditions.
History 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 Kryptonians would take as they grew up. Scientific and technological research were highly valued on Krypton, with the ruling body of Krypton named the Science Council. Several stories featured characters traveling back in time to visit Krypton before its destruction; one example is the 1960 story "Superman's Return to Krypton", in which Superman is swept back in time to Krypton 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 Kryptonian actress
Lyla Lerrol. A
Superman "imaginary story" entitled "What If Krypton Had Not Exploded?" gave more insight into Krypton's society. This era also established that the
Guardians of the Universe, the administrators of the
Green Lantern Corps, were aware of Krypton's pending destruction and assigned
Green Lantern Tomar-Re to avert it, but he was unsuccessful due to being blinded by a
solar flare. In 1980, a three-issue
miniseries titled
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. A three-issue miniseries 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. To do so, he and Supergirl travel to Kandor, where they learn the history of the El family. In 1985, writer
Alan Moore gave a darker glimpse into the world of Krypton in his story "
For the Man Who Has Everything" (in
Superman Annual #11), which takes place in a
dream world where Krypton was not destroyed.
Flora and fauna Krypton has a vast number of flora and fauna, both wild and domesticated. Some of them look very similar to Earth's animals, due to
parallel evolution, e.g.,
birds,
felids,
canids,
simians, etc., as seen in
Krypto and
Beppo; while others look very different, due to
divergent evolution, e.g.,
fish/
snake/
eel-like hybrid creatures called "fish-snakes",
goat-like creatures called "Zuurt",
bovine-like creatures called "
Rondor",
rhinoceros/
ceratopsian-like creatures called Thought-Beasts,
dragon-like creatures called H'Raka,
pterodactyl-like creatures called "War-Kites", gigantic, one-horned
snake-like creatures called "
Drang", and
jellyfish-like invertebrate creatures called Shoggoth.
Moons One of Krypton's moons, Wegthor, was accidentally destroyed by
Jax-Ur, a scientist who was experimenting with a nuclear missile that was diverted from its intended destination. The disaster killed 500 inhabitants of the moon, resulting in Jax-Ur being the first criminal banished to the
Phantom Zone. This disaster also prompted the Science Council of Krypton to ban space flight completely.
Survivors A Silver Age Superman was not alone in the survival of Krypton's destruction, being joined by his cousin
Supergirl, the
Phantom Zone criminals,
Krypto the Superdog,
Beppo the Super-Monkey, juvenile delinquent
Dev-Em, the entire population of the city of
Kandor, and Supergirl's biological parents. When the planet exploded, one entire city of Krypton, Argo City, survived the cataclysm. 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 allowed them to construct a life-sustaining dome and a
lead shield that protected their city from the kryptonite radiation of the asteroid. The protective shield was destroyed in a meteor storm, exposing the inhabitants to kryptonite radiation. The 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. It was later discovered that Supergirl's parents had survived in the Survival Zone, a parallel dimension similar to the Phantom Zone, from which she released them. When Kandor was finally enlarged on a new planet that was similar to Krypton, Supergirl's parents joined its inhabitants to live there.
Daxamites The people now known as the
Daxamites were originally Kryptonians who left their homeworld to explore the universe. In post-
Crisis on Infinite Earths continuity, the
Eradicator, an artificial lifeform programmed to preserve all Kryptonian culture, altered the birthing matrices ("artificial wombs") that the explorers took with them so that all newborns would be fatally vulnerable to lead and other materials such as greenhouse gases and certain rocks. Thus, if they persisted in their anti-Kryptonian wanderlust, they would all die from it. One Daxamite,
Mon-El, was poisoned by lead and preserved in the Phantom Zone until
Brainiac 5 found a cure in the 30th century, whereafter Mon-El became a member of the
Legion of Super-Heroes.
Vathlo Island Vathlo Island is a fictional location on Krypton, notable as an early attempt to explain in-universe the seeming non-presence of
black people throughout the universe. In issue #234 of
Superman (February 1971), the first apparently dark-skinned Kryptonian was featured, and described as being employed at "Vathlo Station", but the origin of this previously unseen Kryptonian ethnicity otherwise went uncommented on. Half a year later, in
Superman #239 (June 1971), a panel drawn by artist
Sal Amendola described a "Vathlo Island" in the "Old World" hemisphere of Krypton as being populated by a "highly developed
black race". It is unknown who exactly was responsible for introducing these first nonwhite races to Krypton's demographic makeup, but
Mark Waid has speculated that it was
E. Nelson Bridwell, editorial assistant on the Superman books at the time. while
Gene Demby observed that this was an example of "segregation in everything". DC Comics writer
Mark Waid called this an "error of omission" coming from DC's desire to represent people of darker skin as living on Krypton, but implementing this in a way with unintended implications. However, other writers have pointed out that DC would go on to re-use this as a rationale to explain the non-presence of black skinned characters in other contexts, as with
Tyroc. Vathlo was rarely if ever referenced beyond these few issues, although a black Kryptonian named "Iph-Ro of Vathlo" appeared in the more recent
Superman: The Man of Steel #111. An offhand reference to the island was made in
Alan Moore's story "
For the Man Who Has Everything", where "racial trouble with the Vathlo Island immigrants" are mentioned in a dream-world Krypton that had avoided destruction. It is believed, based on the appearances of black Kryptonians in recent Superman issues, that the Vathlonians eventually were integrated into Krypton proper, although there has been no canonical statement about this from DC Comics. In
Final Crisis #7 a black version of Superman is shown to reside on the alternate universe of Earth-23. This Superman, also known as Calvin Ellis, originates from Vathlo Island of his reality's Krypton. Characters in
Eric Jerome Dickey's novel
The Son of Mr. Suleman discuss Vathlo Island and react with derision to the idea that there was segregation on Krypton.
Crisis on Infinite Earths After the 1985 miniseries
Crisis on Infinite Earths, the Silver Age version of Krypton was replaced by a newer version. The Silver Age Krypton made a rare post-
Crisis appearance in
The Sandman #48, during a flashback sequence. ===Krypton in the
Modern Age of Comic Books===
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/artist
John Byrne was given the task of recreating the 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 one-and-a-half times larger than Earth and orbited a red sun called Rao fifty
light-years from the
Solar System. Krypton's primordial era produced some of the most dangerous organisms in the universe. It was for this reason that 250,000 years ago, Krypton was chosen as the place to create
Doomsday through forced evolution. Until its destruction, many dangerous animals, including ferrophage moles, still existed on Krypton. Kryptonians had to use their advanced technology to survive. Over 200,000 years ago, Krypton had developed scientific advancements far beyond those of present-day Earth, and had discovered a way to conquer disease and aging by perfecting
cloning; vast banks of clones, kept in stasis, held multiple copies of each living Kryptonian so that replacement parts were always available in the event of injury. All Kryptonians were now effectively
immortal, "with all the strength and vigor of youth maintained", and for millennia they enjoyed an idyllic, sensual existence in an
Arcadian paradise. 100,000 years later, Kryptonian society was tipping toward decadence and eventually political strife resulted from the debate about the use of clones (three by each Kryptonian; one child, one teen and one adult, perfectly preserved in stasis in large clone banks) to repair any hurt and avoiding death, if they were sentient beings and should have rights to be awakened to live as any other Kryptonian, sparked in addition by the presence of an alien missionary known as the Cleric, who carried "the Eradicator". Just as the planet began to shake apart and massive, exploding streams of green energy erupted through the surface of Krypton, Jor-El launched the matrix towards Earth, where it would open and give birth to the infant upon landing (the post-
Crisis Superman therefore was considered to be technically "born" on Earth). Jor-El was not only determined that his son would survive the death of his birthworld, but that he would grow up on a world that vibrantly embraced living, as his forebears once did. In Superman Vol. 2 #18, it is revealed that Krypton still exists as a
gas giant consisting of much of the remaining mass of the exploded planet, which will reform into a solid planet millions of years into the future.
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,
Beppo, 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 engineered by Bertron, an alien scientist, on an ancient Krypton. Doomsday left the planet after killing Bertron and Krypton's natives found the remains of Bertron's lab, thus obtaining the knowledge of cloning. In the newer continuity, Superman also became aware of his alien heritage only sometime after his debut as a
superhero - initially assuming himself to be a human mutated in some manner and launched as part of an Earth space program - when a holographic program encoded into the craft which brought him to Earth uploaded the information into his brain (although Lex Luthor had earlier discovered his alien heritage when his attempts to create a
clone of Superman were complicated by the unexpected x-factor of Superman's alien DNA).
Revisiting Krypton In
Action Comics #600 (May 1988), Krypton was close enough to Earth that the radiation from its explosion (traveling only at light speed) was able to reach Earth. In a 1988 storyline, Superman traveled to the former site of Krypton to discover that the planet was slowly reforming from the vast sphere of debris remaining. It would take millions of years before the planet would be solid again. This sphere of debris had been turned to
kryptonite by the planet's destruction, and the radiation caused Superman to have a
hallucination in which the entire population of Krypton came to Earth and colonized the already inhabited planet, prompting Jor-El to initiate a Terran-based resistance movement, pitting him against his estranged wife Lara and now-grown son Kal-El, at which point the hallucination ended. In a 1999
Starman storyline, Jack Knight became lost in time and space, and landed on Krypton several years before its destruction, meeting Jor-El as a young man. The story implies that it was this early meeting with a human that led Jor-El to study other worlds and eventually choose Earth as the target for his son's spacecraft; at the story's end, Jack gives Jor-El a device with the coordinates and images of Earth. In a 2001–2002 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. This version of Krypton was based on Jor-El's favorite Kryptonian historical period.
Superman: Birthright In the 2004 miniseries
Superman: Birthright, a new retelling of Superman's origin and early years,
Mark Waid located Krypton in the
Andromeda Galaxy 2.5 million light-years away, and adopted elements from several previous versions of the planet. Although usually depicted as a
red giant or
red supergiant, in this story Rao is mentioned by Jor-El to be a
red dwarf. In previous comic versions, it was assumed the "S" shield on Superman's costume simply stood for "Superman"; in
Birthright, Waid presented it as a Kryptonian symbol of
hope; he borrowed and modified a concept from
Superman: The Movie, wherein the "S" was the symbol of the House of El, Superman's family.
Post-Birthright revisions Beginning with
Infinite Crisis, writer
Geoff Johns began laying subtle hints to a new origin for Superman.
Last Son, a storyline co-written by Geoff Johns and
Superman film director
Richard Donner, further delves into this version of Krypton which reintroduces
General Zod and the Phantom Zone criminals into mainstream continuity as well as the crystalline technology known as "
Sunstones". With art by
Adam Kubert, the design of Kryptonian society is distinct yet again from
Birthright, incorporating elements of both pre-
Crisis on Infinite Earths continuity and Donner's work on the first two
Christopher Reeve films, in particular the notion of Krypton's Council threatening Jor-El with harsh punishment if he were to make public his predictions of their planet's imminent doom. This variation of Krypton's past was again seen in flashbacks during Johns'
Brainiac and
New Krypton story arcs. The very different depictions of Kryptonian clothing in the Golden and Silver Age comics, in the Christopher Reeve films, and in John Byrne's
The Man of Steel all appeared in Johns'
Superman: Secret Origin (which superseded
The Man of Steel and
Superman: Birthright). Multi-ethnic versions of Kryptonians that resemble
Africans,
Indigenous Australians,
Pacific Islanders,
Indigenous Americans, and
Asians have also made appearances in the stories. Previously, "black" Kryptonians were mainly confined within the Kryptonian continent of
Vathlo Island, but a 2011 storyline depicted Kryptonians resembling black and Asian humans who were more integrated into Kryptonian society than they were in the Silver and pre-Modern Age DC Universe. In
Action Comics #14 (January 2013
cover date, published November 7, 2012) astrophysicist
Neil deGrasse Tyson appears as a character in the story. He determines that Krypton orbited the
red dwarf LHS 2520 in the
constellation Corvus 27.1
light-years from
Earth. Tyson assisted DC Comics in selecting a real-life star that would be an appropriate parent star to Krypton. He picked Corvus, which is Latin for "crow", because Superman's high school mascot is a
crow. In a 2012 round-table discussion, Tyson stated that he chose to use real science when finding Krypton's location. He explained that many artists may only use bits and pieces of science, allowing for greater latitude in their creativity, but he wanted to show that using real science, particularly astrophysics, allows for just as much creativity. ==Known locations==
