Omota

Omota was the God of Saiyans who was worshipped by the Saiyan race, before it was mostly wiped out. Many descendants of Saiyan survivors still worship him, but many Saiyans did not believe in his existence. There are some planets colonized by Saiyans that have monuments built in honor of this god. On December 31, 1100, Omota merged with Hikari Minato in Other World, making Hikari the new God of Saiyans, and making him permanently in Super Saiyan God form. This also gave Hikari the ability to communicate telepathically with other Saiyans and give power to a Saiyan when they're in need.

About
"Long ago, before the universe was born, there was only one star. This star died and a living being was born from its remains, a god. This god was called Omota and he was the warrior god. The star he was born from possessed some godly power and it decided to create him after it died and it created him to become a god."

- Origin of Omota from the Saiyan holy book, the Book of War

According to legend, Omota was born when a star that possessed some mystical power died and he was created from its remains. He was a mortal at first, like all normal gods. He decided to create stars and planets across the universe and he also created, the original homeworld of the Saiyans. He created many different Oozaru's, powerful simian creatures similar to Earth's gorillas. They were barbarians and tore each other apart, so he evolved them into more intelligent beings, similar to humans. He gave them tails that could turn them into their original bodies whenever in danger and needed to defend themselves. Upon looking at the full moon, these beings that Omota created, Saiyans, would turn into their original Oozaru forms.
