Krypton is the planet where all the Super's come from. Most famously known for being Superman's birth planet but also Supergirl's.


Orbiting a red dwarf star some fifty light-years distant from Earth named Rao, the planet Krypton was once very much like our world. The Green Lantern Corps have dubbed Krypton's sector of space 2813 (Earth's being 2814) and was under the protection of Green Lantern Tomar-Re when it was destroyed. Krypton's primordial era produced some of the most dangerous organisms in the Universe. It was for this reason that Krypton was chosen as the place to create Doomsday through forced evolution. Doomsday was an infant who was released into the dangerous environment of prehistoric Krypton and killed, the surviving and strongest genetic matter was cloned and re-released so the process could be repeated until the resulting being was powerful enough to survive.

He became so powerful, he killed most of the planet's population before clinging to a cargo ship fleeing the planet and went into space with nothing but a strong primal hatred of all life. Doomsday escaped Krypton via a ship that regularly came to deliver supplies to his creator, Bertron, who he also killed and went on a killing spree across several planets. Doomsday faced the Green Lantern Corps, killing several hundred of them, but was ultimately defeated by the alien hero Radiant and entombed. Since it was deemed that keeping them on their planet would be an insult, Doomsday was sent into space, at which time he eventually landed on Earth, tomb, and all. Up until its destruction, many dangerous animals, including ferrophage moles, still existed on Krypton.

In fact, Krypton's inhabitants were indistinguishable from humans, though far more advanced. Kryptonians had to use their advanced technology to survive. Over 100,000 years ago, Krypton had already developed scientific advancements far beyond those of present-day Earth, and within a few millennia had conquered disease, learned to delay 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, "with all the strength and vigor of youth maintained", and enjoyed an idyllic, sensual existence in an Arcadian paradise.

Krypton at one time became an expanding empire that conquered other planets for years. When Krypton was a conquering race, the Kryptonian military was lead by Admiral Dru-Zod the First who commanded entire fleets of ships, seeking worlds ripe for conquest. Some three-hundred years ago, Admiral Zod's capital ship, the Doomsday crash-landed on Earth in the region that would eventually become known as Texas. His Sunstoneship lied buried beneath the ground for centuries. Soon, the Kryptonian Empire was dismantled after the Kryptonian high council decided that their methods were too aggressive. So, ended Krypton's Golden Age.

Destruction Edit

But as Kryptonian civilization flourished, the planet turned towards isolationism. Space exploration was abandoned as Krypton quarantined itself from the surrounding galaxy. All Kryptonians were unable to leave their planet or they would die instantly. This was the result of the Eradicator altering their genetic codes of Kryptonians to keep them planet-bound after a group of them left Krypton to explore and colonize other planets. The Eradicator punished these Kryptonians by altering their genetic codes to be vulnerable to lead, which resulted in the Daxamites.

It was at this time that the young scientist Jor-El and his brother, Zor-El was both born. By their adult years, Jor-El became a high-ranking member of the Kryptonian Science Council and had a wife Lara Lor-Van, from the Labor Guild, while his brother Zor-El became married to Alura In-Ze, and had a daughter named Kara Zor-El. Jor-El was a protege of the eminent scientist known as Non and together they discovered that Krypton was suffering from severe geological disturbances - disturbances that threatened to destroy the entire planet. Jor-El brought his concerns to the Science Council, but they dismissed his assertions as a vehicle of paranoia and discord. Jor-El and Lara even soon had a son called Kal-El.

Many years ago, the penal system of the planet Krypton sentenced their criminals by placing them in suspended animation. Jor-El discovered the existence of the Phantom Zone and introduced it as an alternative means of imprisonment. He had little knowledge of the true inner workings of the zone, but believed that it was a more humane form of punishment over that which they had previously employed. He developed a projection device that could send and retrieve people into the zone with the simple flick of a switch. The first prisoner to be exiled to the Phantom Zone was the renegade scientist Jax-Ur. Jax-Ur, a former colleague of Jor-El's, was responsible for destroying Krypton's moon during an attempt at interstellar space travel. When the moon was destroyed, a lunar colony of Kandor was lost as well, drawing the attention of the Coluan villain Brainiac to Kandor. Brainiac, also known as Vril Dox I, was a Coluan scientist.

At some point, he cloned himself to get a lab assistant; the clone would later be called Vril Dox II. He acquired a spaceship and went on a journey through space, acquiring knowledge and using his robotic drones to capture living organisms of various alien species. Along the way, he came to Krypton some time during the lifetime of General Zod, and kidnapped the entire city of Kandor, miniaturizing it in his spaceship, while Jor-El 's brother, Zor-El and his family stayed behind at Argo City. An elite military unit, called Black Zero, commanded by General Zod's wife, Ursa was killed attempting to defend Kandor from Brainiac, except Ursa herself. Brainiac also created a remote scout unit, which was programmed to think it was the original Vril Dox. After Brainiac's attack, Zor-El created a force field around Argo City using a Braniac Probe. Over a short expanse of time, the Kryptonian Science Council began exiling the worst of the planet's criminals into the zone, the most famous of which was the military insurrectionist General Zod.

General Zod, the descendent of Admiral Zod, gained prominence in the Kryptonian Military Guild for his heroic, though futile, efforts to protect the city of Kandor from Braniac, however lost credibility however when he defected from the Kryptonian Defense Council, along with his wife Ursa, after they had been instructed to arrest Jor-El and Non after they both had made sensationalistic claims of Krypton's pending destruction. But, suddenly Non was abducted by the Kryptonian Science Council for continuing the claims and was brainwashed, lobotomized, and turned into a brutish, mute savage by the Council to be silent. When Zod, Ursa, and Jor-El found out, both Zod and Ursa sided with Jor-El. But, they both and Non were arrested and tried for acts of sedition. They were sentenced to spend eternity in the Phantom Zone, where they would continue to exist as disembodied wraiths by Jor-El, which lead to their revenge against him and his heirs.

Jor-El was later threatened by the Science Council with harsh penalty of exile to the very Phantom Zone he himself had discovered if he were to make public his predictions of their planet's imminent doom or otherwise attempt to "create a climate of panic". So he decided to create a star-drive ship designed for his only son, Kal-El, to escape the planet and its people's fate. Also, Jor-El had created a serum that he invented that would allow a Kryptonian to leave the planet safely; which he gave to his son Kal-El upon leaving for Earth. He also had his family dog in his household, Krypto used for a test flight of the rocket that would carry baby Kal-El to Earth. His niece, Kara is actually older than Kal-El; she was a teenager when he was a baby.

But, before he can do so, Jor-El explored the galaxy in search of a suitable planet and sent out dozens of probes designed to collect various data. His research revealed that Kryptonians living in a yellow-star system developed enhanced physical characteristics including super-strength, speed, and agility. One of Jor-El's probes landed on the planet Earth where it was discovered by motorist Thomas Wayne while he was on a drive with a pregnant Martha. When Thomas touched the probe, his consciousness was instantly transported to Krypton where he met Jor-El so that Jor-El could better learn what kind of world Earth was to help him decide which of many possible candidates he should sent his son to. Although their meeting was brief, Jor-El developed a fondness and respect for Thomas Wayne. Thomas tells Jor-El that the people of Earth aren't perfect, but are essentially a good and kind race, who would raise the child right. He decided that Earth would be the perfect planet for his son to be raised. Thomas recorded his encounter in his diary, which was discovered by his son, Bruce Wayne in the present day.

The planet was an enigma to all but itself when internal pressures in Krypton's volatile core led to its destruction. Within a period of time, Jor-El's worst nightmares came to pass. Massive groundquakes erupted across the planet and Krypton literally shook in its death-throes. With little time to spare, Jor-El and Lara placed baby Kal-El into his rocket ship and sent him towards Earth. Meanwhile, Brainiac returned to consume Argo City, Kara's parents had no choice but to send her in a rocket headed for Earth.

However, her rocket was caught in a large Kryptonite encrusted meteor and she arrived on Earth years after her cousin did. It was because of this, she obtained Kryptonite Poisoning where she would seem to act petulant, having sudden mood swings causing her to shift from one personality to another, had trouble concentrating on what she was doing and had crystals that appeared out of her skin (crystallized blood). Also, Krypto was too sent to Earth, but his rocket was blown off course and drifted in space for many years until the rocket picked up the signal from Kal-El's rocket that landed on Earth. Krypto arrived when Kal-El was a teenager, and the two got along famously. Krypton exploded and everyone on the planet, including Jor-El, Lara, and the Kryptonian Science Council were killed. Now, all that remains of a once great world is a particle cloud of radioactive dust.


"Rao" is also later written into the Superman mythology as the name of a Kryptonian deity, the personification of their sun, worshiped as a god of light and life. As such the name was sometimes invoked in the comics as a Kryptonian exclamation.

According to the Kryptonian mythology, Rao is the first being to be born out of the void before the universe. Feeling lonely, he sought to bring order to the chaos from which he was born, and thus created the universe. After countless eons of ordering the cosmos, Rao created Krypton, a planet meant to be a jewel in his creation. Rao then created all the other Kryptonian gods from his own essence, and these "godlings" called him "Father Rao". Rao, in the time just before and after the destruction of Krypton, is thought of by the people of Krypton like the God in Abrahamic Religions is on Earth. He is all knowing, all powerful and eternal. He is served by his minor gods, who could be better understood as his angels. Each minor god is worshiped by a guild or caste on Krypton while all people worshiped Rao.[volume & issue needed]

The people of Krypton call their powers under a yellow sun the power of Rao. The high priest of Krypton is said to be the Voice of Rao and only speaks to voice Rao's judgement. Rao works through avatars.
