No entity is truly omnipotent except for one in each fictional continuity. All gods are only technically nigh-omnipotent, since they have two specific limits preventing them from achieving absolute omnipotence.
One, they can't affect omnipotence wielders with a higher or equal ^ to their own, and they can't escape The Box.
True omnipotence means that one has no limits, only bound by fiction, but there are some things that surpass fiction to a certain point, and even entirely, as shown in the paragraph below levels of omnipotence.
Ultipotence is Omnipotence without the omniscience or variable omnipresence. Ultipotence can still have ^ levels, such as Ultipotence^4 (Kotoblade)
Certain characters aren't listed here, for the simple fact that their subcategory isn't available on this page. They're still well within the hierarchy.
Please place your omnipotent beings within here if they're within the ranking.
Levels Of Omnipotence
Nigh Omnipotent - Three or more limits that prevent them from reaching omnipotence.
Omnipotent - Only two limits, can't affect Omnipotent^2.
Known wielders - Creator
Omnipotent^2 - Only two limits, can't affect Omnipotent^3.
Omnipotent^3- Only two limits, can't affect Omnipotent^4.
Known wielders - Conceptilum
Omnipotent^∞ - Only two limits, can't affect true omnipotence users.
True Omnipotence - No limits whatsoever, only bound by fiction itself.
Known wielders - The True God
Then there's Author Authority, which is an entirely different story, being able to partially transcend fiction, able to rewrite the fictional plane they exist on. This can only happen with self-insertion (characters representing writers, maybe an author, such as Toribot from the Dragon Ball continuity)
Transfictional Author Authority
It is the ultimatum of power within transcendent reality. Users of Transfictional author authority can affect any fictional continuity on a true omnipotent level, with no limits.
Nobody has this since there is nobody who can illustrate every fictional continuity.
