Earth 9: Hyperman's Origins
Within many universes there is a world that was known as Krypton which was the home world for a technology advance race called the Kryptonian and that technically true in this universe as well however within in this universe Krypton has a different name which is Yttrium and Kryptonian's are called Yttriumite's. However one day Yttrium was attack by the Warzoons from Warworld was a mobile planetoid that was ruled by Tartarus who was a hybrid, half Warzoon and half New God as his father was the evil New God Darkseid the ruler of Apokolips and even though the Yttriumite's had advance technology they still lost however before their world was destroyed many Yttriumite's managed to escape and one of them was a Yttriumite soldier Vor-Em who's ship was knock off course when Yttrium exploded causing him to be sent to a different world from the rest of his race and the world he landed was Earth.
When Vor-Em spaceship reach Earth it landed in the United States of America near a seacoast town, immediately Vor-Em took his ship and left the area before anyone could discover him and he used the computer systems within his ship to forge himself a fake identity and gave himself the Human name Tom Edwards and afterwards Vor-Em travel all across Earth learning everything he could and eventually he moved to the big city known as Cosmopolis and it was there where Vor-Em became the superhero known as 'Hyperman' because of the symbol on Vor-Em Hyperman costume which was actually Yttriumite armor and it also had the symbol for the 'House of Em' on the chest which looked like a 'H' inside a circle however on Krypton it wasn't a 'H' instead it is the Yttriumite symbol for truth.
Not to long after Vor-Em met other people who also possesses super powers similar to his own like Thor who was an Asgardian and the God of Thunder, Tony Stark who was known as Iron Man, Steve Rogers who was known as Captain America, Bruce Banner who was known as the Hulk, Carol Danvers who was known as Captain Marvel, Peter B Parker who was known as Spider-Man, T'Challa who was known as Black Panther, Clint Barton who was known as Hawkeye, Natasha Romanoff who was known as Black Widow and many other superheroes and together they became known to the world as 'The Avengers'.
Hyperman is a name used by several characters created as analogues to Superman
In the DC Comic 'Superman: The Coming of the Superman' Vor-Em is one of three Kryptonian's that came to Earth each wearing a Superman costume
Yes this Universe is basically the Marvel Universe although it will have elements from Marvel Universe
