Earth 6: Superman's Origins

There was once a peaceful world that was known as Krypton which was the home world for a technology advance race called the Kryptonian's who were they known as one of most advanced civilization in the known universe and they were governed by the Ruling Government and their society was different from many other races in the Universe as unlike other races Kryptonian's are not born though natural means anymore as instead they are created in the Birthing Matrix which was a chamber where Kryptonian children are artificially created to ensure that the Kryptonian children are born perfectly healthy.

Krypton had always had a bad relationship with the Thraxan's who were from the world known as Flaxan which was a nearby planet to Krypton and they have hated each other simply because of their various differences, such as Democracy vs Monarchy and how life should be lived which eventually led to a war between the two world's.

The war between Krypton and Flaxan lasted for many years with casualties between the two world's were in the thousands which cause both the Ruling Government of Krypton and the Zaxal royal family of Flaxan to finally call a end to the war however not everyone wanted the war to end because they wish to avenge their fallen friends and family like General Dru-Zod who was a distinguished soldier in the Kryptonian Military Guild like almost every single other member from the well-known and respected 'House of Zod' and he wanted to avenge all of the lives of the Kryptonian's that had been killed by the Thraxan's during the war.

Dru-Zod believed that the current Ruling Government was weak and so that Krypton needed a stronger leadership to led Krypton into becoming a great galactic empire in the Universe which it was destined to be meaning himself and Dru-Zod became even more certain of this when he had discovered that the Ruling Government had a secret weapon that they could have use to completely destroy the Thraxan's and won the war for Krypton at the very beginning of the war against the Thraxan's and the secret weapon was a creature known as Doomsday who possessed unimaginable power and bloodlust.

Many years ago on Krypton there was a civil war that was started by a rebel group who called themselves 'Black Zero' so the house's that were members of Krypton's Science Guild like the famous 'House of El' work together to create a weapon to stop Black Zero which led to the creation of Doomsday to put a end to the civil war and protect Krypton. However their creation proved to be far to violent to be controlled and to powerful to be destroyed so the Ruling council of Krypton at the time used a device which was created by Val-El call the Phantom Zone Projector which can send anyone or anything to the Phantom Zone an intra-dimensional realm outside the normal space/time continuum which would later become a prison where the Ruling Government would send the worse criminals making Doomsday it's first ever inmate.

The current Ruling Government was too afraid to unleash Doomsday from the Phantom Zone on to Thraxan's fearing that what if they did free Doomsday but they couldn't be able to send him back to the Phantom Zone and the creature may also end up destroying them as well. Dru-Zod gathered everyone who also share in his vision for a grand military government Krypton and they call themselves 'The Sword of Rao' after their Sun-God Rao however the Ruling Government was able to stop to them thanks to the help from Jor-El who was the great grandson of Val-El, one of Krypton's greatest scientists and the former best friend of Dru-Zod.

Afterwards the Ruling Government sentenced Dru-Zod and most of his followers to the Phantom Zone but not before Dru-Zod vowed vengeance and he claimed that they have doomed Krypton as the war had left both Krypton and Flaxan defenses weakened and neither of them were prepared when Brainiac came to their world's.

Brainiac was originally from the Planet Colu and his name was Vril Dox where he was one of Colu greatest scientists however he became obsess with gaining knowledge which led to he to try steal all knowledge from Colu but he was stop and before he was caught he escape the planet and he would greatly modify his ship and himself with him taking the name of Brainiac and not long after he created a device that could struck entire cities and people so he could transportation the small orbs on his Skull Ship so he could continually study the lifeforms and exterminate them.

Brainiac choose Krypton first simply because it was a bit more weaker then Flaxan because of the lost of Dru-Zod and his followers and when Brainiac arrive he chose one of Krypton's three greatest cities known as Kandor to be added to his collation and sent his drones to gather everyone who it thought was useful and those who he didn't were killed while Brainiac also hack into every computer system of Krypton to downloaded all of it's knowledge. Once Brainiac was finish he then fired a blast from hid Skull Ship into the Planet's core triggering it's destruction like he has done to every other world he has come to as Brainiac wanted to make the knowledge that he had gathered only available to itself and Brainiac then travel to Flaxan to repeat what it had just done by taking it's crown city of Klaxia.

However a few weeks before Krypton's destruction Jor-El had found out that Brainiac was heading towards his world but when Jor-El try to warn the Ruling Government they simply ignored his pleas for evacuation and later expelled him from Krypton's Science Guild and so with the little of restores that Jor-El had he was able to build not one but two spaceships one for his wife Lara Lor-Van sent their baby son Kal-El and the other for himself to be sent to world known as Planet Earth.

Jor-El had discovered the planet because years ago he had sent out a satellite into space for research and Kal-El would be able to blend in with the inhabitants of Earth who are call Human's as they look identical to Kryptonian's and because Planet Earth had a yellow sun unlike Krypton's which had a red sun there were side effects on Kryptonian Physiology which were that the yellow sun radiation can grant Kryptonian's incredible powers.

Jor-El also made sure Krypton's legacy wouldn't be lost by creating a special Crystal which could transform into a large fortress that contained many of Kryptonian technologies and a special orb which Jor-El had originally created for the Ruling Government back during the war against Flaxan with it purpose being able to contain a large amount of knowledge as the Ruling Government had intended to use it to copy all of Thraxan's knowledge to use against them but instead Jor-El had use it to copy all of Krypton's knowledge before Brainiac downloaded it into itself however when Krypton exploded it caused Lara's and Kal-El's spaceship to be knock off course meaning that their ship while was still heading to Earth wouldn't arrive at the same time as Jor-El.

However unlike in other Universes everything that happen on Krypton happened far sooner and everyone that was there existed far sooner as well meaning Jor-El's spaceship arrived on the planet Earth in 1922 in the United States of America in Kansas near a small town known as Smallville and he immediately try to find out where while his family so he used Crystal which led him to the Arctic Circle where he then use it to create a fortress of solitude and had it combine with the orb of knowledge as all forms of Kryptonian technology was capable of merging with any other forms of Kryptonian technology as well as even other technologies that isn't Kryptonian and he found out that they were thankfully still alive but it would be sometime before he sees them again.

Jor-El then spent years first to control his new powers and then traveling the world learn everything he can about his new home and he created a fake identity for himself called 'Joel Starr' however in 1939 the Second Great World War started and Jor-El choose to fight in the war using his super powers while wearing Kryptonian armor with the symbol for the House El on the chest which looked like a 'S' inside a diamond shape which caused people began to call him 'Superman' and use him as their symbol of hope during those dark times while Jor-El wanted to not just help save lives and end the war but also to ensure that the world that his wife and child will arrive on will be a good one.

During the war he met other people who also possesses super powers similar to his own like Queen Hippolyta of Themyscira who was known as Wonder Woman, Thomas Wayne who was known as Batman, Abin Sur who was a member of the Green Lantern Corps, Jonathan Chambers who was known as The Flash, Queen Atlanna who was known as Aquawoman, Amaya Jiwe who was known as Vixen, William Blake Everett who was known as Amazing Man, Abigail Hunkel who was known as Red Tornado, Jared Stevens who was known as Doctor Fate, J'ann J'onzz who was known as Miss Martian, John Diggle who was known as Green Arrow and many other superheroes and together they became known to the world as 'The Great Society'.
