How powerful is Superman Prime from the One Million series?
So, I recently watched Screwattack's Goku versus Superman Death Battle—good battle by the way—when I came across a few odd comments in the comment section outright stating that Superman Prime (from the One Million series) was the strongest fictional character second only to God himself, and that it has been confirmed that Superman Prime is second only to the Presence.
I asked one of the gentlemen where he got this from to which he replied "If you read the comics you would know."
Admittedly I never took the time to read the One Million series, but from my experience on this forum he's not quite all that. Then again I do know that people here are more focused on feats than what's being said, so my questions are.
Has it been confirmed that Superman Prime is second only to God or the Presence?
If not, where would you put him in terms of power?
