(I don't own the rights to any of these characters I'm just a fan making a story, I will be using characters and things from other comic book franchise like Marvel comics, Image comics, WildStorm comics and The Boys as well as I may use the names of characters, backstories and things within this story)
Earth 3: Superman's Origins
There was once a peaceful world that was known as Planet Daxam which was the home world for a technology advance race known as Daxamites however their race weren't originally from that world as they are descendants from another technology advance race call Kryptonian's from the Planet Krypton who colonised the Planet Daxam however because they were separated from Krypton and over the time of hundreds of years their culture changed where they didn't consider themselves Kryptonian's so instead they call themselves Daxamites and unlike Krypton which is ruled by the Ruling Council, Daxam however was governed by a monarchy of the descendants of who had led the Kryptonian colonists.
However one day Daxam was attack by the Warzoons from Warworld was a mobile planetoid controlled by alien tyrant Mongul and even though the Daxamites had another technology they still lost however before their world was destroyed many Daxamites managed to escape and one of them was the Prince of Daxam Lar Gand who's ship was knock off course when Daxam exploded causing him to be sent to a different world from the rest of his race and the world he landed was Planet Earth.
When Lar Gand's spaceship reach Planet Earth i was damaged meaning he was stranded on Earth, so he used his ships computer to create a fake identity for himself so he could blend in with the inhabitants of Earth who are call Human's as they look identical to Daxamites and gave himself a human name which was Mike Matthews and he soon discovered that because Planet Earth had a yellow sun unlike Daxam's which had a red sun there were side effects on Daxamites Physiology which were that the yellow sun radiation can grant Daxamites incredible powers.
He began using them to help people in need became the superhero known as Superman and not to long after Lar Gand met other people who also possesses super powers similar to his own like Barda Free who was a New God from Apokolips where her name was Big Barda however she escape and flew to Earth where she became known as Wonder Woman, Timothy Fox who was known as Batman, Guy Gardner who was known as Green Lantern, Meena Dhawan who was known as The Flash, M'yrnn J'onzz who was an Martian from the planet Mars and he was known as the Martian Manhunter, Kendra Munoz-Saunders who was known as Hawkwoman and many other superheroes and together they became known to the world as the 'Justice Guardians'.
Like what i said on the first chapter: The Multiverse, all the evil Earth's exists in the Antimatter Multiverse which is why Earth 3 isn't the home universe of the Crime Syndicate in this story
In DC Comics Daxam is a sister planet to Krypton orbiting the same red star however in this story its far from away from Krypton in another solar system
In DC Comics Lar Gand other name is Mon-El as when he had first came to Earth he had lost his memories and when Superman found him he saw that he had his families crest and he thought maybe he could possibly be his brother but he needed a name until his memories return and so Superman gave him the name Mon-El with the mon part coming from Monday which was the day arrived and El because he thought he was a member of the house of El
In DC Comics Mon-El protected Metropolis when Superman had left Earth and was living on New Krypton
In the Justice League Gods and Monster's the Wonder Woman of that Universe was a New God from New Genesis who's name was Bekka so I thought why not do something like that and I decided to use Big Barda
In DC Comics Timothy Fox becomes the new Batman in Future State
In DC Comics Guy Gardner is one of Earth's Green Lanterns
In DC Comics Meena Dhawan is the speedsters known as Fast-Track
In DC Comics M'yrnn J'onzz is the brother of J'onn J'onzz
