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

Earth 7: 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 Council and their society was different from many other races in the Universe as unlike other races Kryptonian's are not born though natural means instead they are created in the Birthing Matrix which was a chamber where Kryptonian 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 world's.

The war between Krypton and Dheron lasted for many years with casualties between the two world's were in the thousands which cause both the Ruling Council 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 Dru-Zod who was a distinguished soldier in the Kryptonian military 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 Dheronian's during the war.

Dru-Zod believed that the current Ruling Council 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 Council had a secret weapon that they could have use to completely destroy the Dheronian's and won the war for Krypton at the very beginning of the war against the Dheronian'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 calling themselves 'Black Zero' so the house's that were members of Krypton's Science Council 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 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 Council would send the worse criminals making Doomsday it's first ever inmate.

The current Ruling Council was too afraid to unleash Doomsday from the Phantom Zone on to Dheronian'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 Council 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 Council 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 however no one knew that Dru-Zod was technically true as the war between their two world's had greatly damage both world's cores and it would led to both world's being destroyed all expect for Jor-El who discovered it because a series of earthquakes rocking Krypton.

When Jor-El try to warn the Ruling Council they simply ignored his pleas for evacuation and later expelled him from Krypton's Science Council so with the little of restores that Jor-El had he was able build a small spaceship and on the day of Krypton's destruction had arrive, Jor-El and his wife Lara Lor-Van sent their baby son Seg-El who was name after Jor-El's father and he was the first Kryptonian to be born though natural means after centuries 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 Seg-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 that Seg-El 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 technologies and a special orb which Jor-El had originally created for the Ruling Council back during the war against Dheron with it purpose being able to contain a large amount of knowledge as the Ruling Council had intended to use it to copy all of Dheron's knowledge to use against them but instead Jor-El had use it to copy all of Krypton's knowledge.

However Seg-El wasn't going to be the only Kryptonian that is sent off Krypton before it's destruction as he had a older half brother Tal-Rho who was the son of Zeta-Rho and Lara Lor-Van, within Kryptonian culture people are genetic matched together however Lara and Zeta's marriage was a loveless but during the war against Dheron's Zeta was killed and Lara remarry to Jor-El who treated Tal like a son far better then Zeta did and Jor-El was able to build a spaceship for Tal and gave the same Crystal and orb as the one's that he gave to Seg-El however when Krypton exploded it caused Seg-El spaceship to be knock off course and causing him to go to a different world which was the planet Almerac where Seg-El would be found, raised and eventually married the queen of Almerac Maxima and become King.

Meanwhile when Tal's spaceship reach Planet Earth it landed in the United Kingdom of Great Britain in a forest where he was founded by Robert and Claire Kingsley who were camping nearby and when they found Tal in his spaceship and they decided to adopt him and gave him the name of Taylor Kingsley him and they raised Taylor as their own and taught him their values. Taylor grew up happily thanks to him having good parents and great friends and Robert used his powers to help his family on their farm but only there as Robert had told Taylor that other people may be afraid of him because of his powers and the fact that he was a alien.

Tal traveled the world for a bit until he used the Crystal that he had found inside his spaceship which Jor-El had given him and he travel in the direction which the Crystal glowed which led him to a desert 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.

Tal eventually moved to the big city known as London where he would used his intellect and the knowledge of Kryptonian technology to start his own company called 'Galaxy Holdings'and it was also there in London where Tal became the superhero known as 'Superman' because of the symbol on Tal's Superman costume which was actually Kryptonian armor and it also had the symbol for the 'House of Rho' on the chest which looked like a 'S' inside a diamond shape shield that was slightly tiled however on Krypton it wasn't a 'S' instead it is the Kryptonian symbol for order.

Not to long after Tal met other people who also possesses super powers similar to his own like Orana of Themyscira who was known to the world as Wonder Woman, Jean-Paul Valley who was known as Batman, Carol Ferris who was known as Star Sapphire, August Heart who was known as The Flash, Orm Marius who was known as Aquaman, Jason Rusch who was known as Firestorm, Ma'alefa'ak who was known as Martian Manhunter, Shen Li-Men who was known as Hawkwoman and many other superheroes and together they became known to the world as 'The Justice Battalion'.
