Entropy is the thing that will end our universe and likely many other universes, so how does the Omniverse keep entropy at bay? It's very simple, upon death all living beings, from the smallest bacteria to the largest galaxy eater, become gods of their own universe. Their universes harbour more and more life, which will eventually become gods of their universes, and that's not even counting alternate timelines, so the Omniverse is growing exponentially fast every millisecond.
Now that you have perished it's your turn to claim your divine right, and the Omniversal Embodiment will grant you any powers and build you any universe you desire, so even if you don't want to be a god you can still have a nice little Isekai adventure if you want instead.
Rules:
No Omnipotence or any expression of Omnipotence.
Your powers will cease to function if you leave your universe.
Technically any Absolute or Almighty powers are going to not be so Absolute because of the rule above, you can still pick them, just know that your powers will basically just be Nigh-Absolute or Nigh-Almighty. I guess the same goes for Omni and Meta powers too.
What powers will you gain?
What universe will make or ask the Omniversal Embodiment to make?
What are you going to do with your newfound powers?
Anything else?
