You forget that there are Omnipotent beings in fiction who are not subject to change. Beings who have always been such as Eru Iluvatar from Tolkiens works. In the end it is the writer, not the wiki, that has the final say since a lot of these ideas were around in the minds of writer long before the wiki existed.

But back to the main topic.

The most powerful power...

Technically Omnipotence, but since Void Walker said Omni-Creator and Omni/Totality Embodiment were allowed, I'd say it be a tie between both Omni-Creator and Omni-Embodiment since both allow you to control or be EVERYTHING.
