I'm not sure because to be omnipotent is to be powerful then all meaning there can only be one
And if the omnipotent being decide that there are two omnipotent being and then kill the second omnipotent being
Omnipotence is so complicated to be fully understand by us, it is my point of view
There can only be a single omnipotent being, the moment that one is stronger than the other or both possess the same power them neither of them is truly omnipotent.
What do you think?
