(The Dheronian was a race that had a war with Krypton within the Earth One Universe in the comics)

Earth 4: 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 who were governed by the Ruling Government and their society was different from many other races in the Universe as unlike other races Kryptonian are not born through natural means instead they are created in the Birthing Matrix which was a chamber where Kryptonian's children are artificially created and they are raised in separate from their parents until they reach a certain age.

Krypton had always had a bad relationship with the Dheronian's who were from the world known as Dheron 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 worlds.

The war between Krypton and Dheron lasted for many years with casualties between the two worlds were in the thousands which cause both the Ruling Government of Krypton and the monarchy of Dheron 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 Druzod who was a distinguished soldier in the Kryptonian's 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 that had been killed by the Dheronian's during the war.

Druzod 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 making himself the Grand Regent of Krypton and Druzod became even more certain of this when he had discovered that the Ruling Government had a secret weapon which they could have use to completely destroy the Dheronian's and won the war for Krypton at the very start of the war against the Dheronian's and their 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 calling itself 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 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 Valel call the Negative Zone Projector which can send anyone or anything to the Negative Zone an inter-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 Negative Zone on to the Dheronian's fearing that what if they did free Doomsday but they wouldn't be able to send him back to the Negative Zone and the creature may also end up destroying them as well. Druzod gathered everyone who also share in his vision for a grand military government Krypton and they call themselves 'The Blades of Rao' after their Sun-God Rao however the Ruling Government was able to stop to them thanks to the help from Jorel who was the great grandson of Val-El, one of Krypton's greatest scientists and the former best friend of Druzod.

Afterwards the Ruling Government sentenced Druzod and most of his followers to the Negative Zone but not before Druzod vowed vengeance and he claimed that they have doomed Krypton as the war had left both Krypton and Dheron defences weakened and neither of them were unprepared when Nimrod came to their world's. Nimrod was a artificial intelligence machine originally from the Planet Colu called Computo and it was designed to gather date and study all forms of life however it went rogue and left the Planet Colu knowing that if it stay it's creator Vril Dox who created Computo by basing it from his own brain patterns and the other scientists would be able to destroy it and once it left Planet Colu it created itself a spaceship and a physical body which it had designed to look like it's creator Vril Dox and gave itself a new name Nimrod and afterwards Nimrod continue its original mission to gather knowledge which has led it to create a device that can struck cities are people so Nimrod could transportation the small orbs on its Skull Ship so Nimrod could continually study the lifeforms and exterminate them.

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

However a few weeks before Krypton's destruction Jorel had found out about Nimrod but when Jorel try to warn the Ruling Government they simply ignored his pleas for evacuation and later expelled him from Krypton's Science Guild so with the little of restores that Jorel had he was able build a small spaceship and on the day that Nimrod had arrive, Jorel and his wife Lara Lorvan sent their baby son Segel who was name after Jorel's father and the first Kryptonian to be born through natural means after centuries to world known as Planet Earth. Jorel had discovered the planet because years ago he had sent out a satellite into space for research and Segel would be able to blend in with the inhabitants of Earth who are call Human's as they look identical to Kryptonian and because Planet Earth had a yellow sun unlike Krypton which had a red sun there were side effects on Kryptonian's Physiology which were the yellow sun radiation granted Kryptonian's incredible powers.

Jorel also made sure that Segel would know about his family's legacy by giving him a special Crystal which could transform into a large fortress that contained many of Kryptonian's technologies and a special orb which Jorel had originally created for the Ruling Government back during the war against Dheron with it purpose being able to contain a large amount of data as the Ruling Government had intended to use it to copy all of Dheronian's knowledge to use against them but instead Jorel had use it to copy all of Krypton's knowledge before Nimrod had downloaded it into itself.

However Segel wasn't the only Kryptonian that was sent off Krypton before it's destruction as his cousin Kara-Zorel was also sent to Earth as well thanks to her father Zorel who was Jorel's younger brother as he believed his older brother's warring so he also built a spaceship as well which he and his wife Alura Inze place their daughter inside and in a cryo sleep and as they sent her to Planet Earth and they told her to have a good life as well as protect her cousin however when Krypton exploded it caused Kara's spaceship to be knock off course meaning that her ship wouldn't arrive on Earth at the same time as Segel.

When Segel's spaceship reach Planet Earth it landed in the United States of America in Kansas near a small town known as Smallville where he was founded by William and Maria Kent who were farmers and they were on their way back home from the doctor's after finding out that they sadly are unable to have children of their own so when they found the baby Segel in his spaceship they thought of him as a blessing and they decided to adopt him and gave him the name of Ronan Kent with them choosing Ronan because it was name they would have used if they were able to have a son and it was also the name of Maria's father as they wanted to honor him and they raised Ronan as their own and taught him their values.

Not after there was the biggest snowstorm that Smallville has ever seen which lasted five months and during that time William and Maria kept to themselves while trying come up with how they were going to explain to their friends and family where Ronan came from, Maria's sister Monica Clark work in the government and was able to make a identity for Ronan claiming that he was their biological son who was born during the snowstorm while they didn't tell Monica Ronan's true origins instead they told her that they found alone where he was abandoned by his biological parents and the reason why they didn't want to go to the authorities was because they wanted to be the ones to adopt him just in case the authorities wouldn't allow as they were on the waiting list and they might give him to those who were ahead of them.

Ronan grew up happily thanks to his good parents and to him having great friends like Lana Lang, Kyle Cushing, Chloe Sullivan and Pete Ross but eventually William and Maria told Ronan the truth of his origins when he was old enough however Ronan had always know that he was different from everyone else because of his incredible powers which he secretly uses to help his family on their farm but only there as William had told Ronan that other people may be afraid of him because of his powers or the fact that he was a alien but Ronan wanted to be like the Superheroes that existed back during World War 2 who were apart of a team called'The Law's Legionnaires'.

On the night of Smallville High prom both William and Maria were driving home where they were also crash into another car and Ronan heard Maria's scream because of his Super-Hearing and with his Super-Speed Ronan immediately rush over to save them however he was too late to save either of them and Ronan blame himself as he thought that if he wasn't scare to use his powers then maybe he wouldn't be late to save their lives and so he vowed to truly master his powers so that next time when he tries to save someone then he won't fail again.

Ronan then traveled the world for a bit until he used the Crystal that he had found inside his spaceship that his father Jorel had given him and he travel in the direction which the Crystal glowed which led him to the Bermuda Triangle 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. Ronan eventually moved to the big city known as Metro News where he became a reporter for the Metro News and it was there in Metro City where Ronan became the superhero known as 'Superman' because of the symbol on Ronan's Superman costume which was actually Kryptonian armor and it also had the symbol for the House of El on it which looked like a 'S' inside a diamond shape shield however on Krypton it wasn't a 'S' instead it was the Kryptonian symbol for hope.

Not long after Ronan met other superheroes like Unatti of Themyscria who was known to the world as Wonder Woman and whom Ronan fell in love with and married, Terrance Wayne who is also known as Batman, José Hernandez who is also known as Green Lantern, Tanaka Rei who is also known as The Flash, Ahmed who is also known as Hawkman, Adam Cray who is also known as The Atom and many other superheroes and together they became known to the world as the 'Justice Alliance'.

This variant of Superman was inspired by the Superman of Earth D and the Superman of Earth 23 aka Calvin Ellis, Kalel and President Superman however that version dose exist within this DC Multiverse on Earth 23

I got the name Justice Alliance from Earth D in DC Comics

The Law's Legionnaires are a alternate name for the Seven Soldiers of Victory

Unatti is the name of Wonder Woman from the DCAU: Earth D

Terrance Wayne is the name of Batman from the DCAU: Earth D

José Hernandez is the name of Green Lantern from Earth D

Tanaka Rei is the name of the Flash from Earth D

Ahmed is the name of Hawkman from the DCAU: Earth D however we don't know his last name

In DC Comics Adam Cray is the second Atom, replacing Ray Palmer who was engaged in an undercover mission however originally i want to use the Atom from the original Earth D but we don't know what his name is

I got the name Metro City from the 2010 animated film Megamind

I got the name Nimrod from Marvel comics who is a mutant-hunting Sentinel from an alternative future timeline and was created by the Sentinels that were ruling that timeline, I just needed a different name for the Nimrod of this Universe

In Marvel Comics the Negative Zone is a mysterious dimension discovered by Reed Richards aka Mister Fantastic however in this story it's just the Negative Zone with a different name

I got the name Ronan Kent from DC Future State where there was a Ronan Kent who was from 30th Century where he is a descendant of Clark Kent and he was the Superman of Earth just like Brandon Kent

Like how Brandon Kent of Earth 1 Superman costume looks the Hyperion from Earth 13034 costume Ronan's Superman costume will be different as well as it look like the Blue Marvel/ Adam Brashear costume who is another Superman analogue from Marvel Comics, his costume will dark blue and white but with the Superman's symbol
