If I'm not mistaken, this wiki doesn't use the term "Omnipotent". The
Omnipotence page mentions this: "given the highly logically self-contradictory nature of the "can do anything whatsoever" definition of omnipotence (see the above image for an example), within this Wiki even characters with the highest "0" ranking are only described as having "Questionable Omnipotence"."
And the description of
Tier 0 is: "Beings that are boundlessly above absolutely everything, including existence and nonexistence, possibility, causality, dualism and non-dualism, the concepts of life and death, and their analogues at any level."
