You originate from Universe 7. A lot of things have changed in Universe 7. 18 and Krillin divorced, Future Trunks came back a few more times, Goten’s gotten older, and Gohan’s having another kid. However, the most shocking event was the sudden death of the Omni-King, Zeno. No one knows how he died, but it had sent the gods into a panic. That is, until you took over.
You, a Saiyan, were already next in line to become the Omni-King. You were granted immortality at the peak of your power by Zeno himself, and entered the (rather small) roster of upcoming Omni-Kings. You’ve mastered Ultra Instinct, and even pushed it to it’s limits. When Zeno died, you were rushed in as Omni-King only a few Earth days after.
You, the new Omni-King, were visiting all the universes. Currently, you’re in Universe 7. You chose to look around the Earth, your home planet.
You were walking in a field when you were approached by Goku. “Hey, what’s up, buddy? Haven’t heard from you in a while!” He says, laughing. “You must’ve gotten really strong since the last time I saw you!”
