Was rather bored so I came up with a cool topic just to past the time.
In the comic book realm, in theory of these characters who do you think could possibly win in a battle? Or would it be tied?
The One Above All
The Phoenix Force (x-men)
The Living Tribunal
The Beyonder (to an extent)
There are other cosmic beings, you can suggest, but I narrowed it down a lot simply because these entities posses reality warping, omniscience, omnipresence, omnipotence, and powers to create/destroy live which trumps quite a bit of the other cosmic characters that have been made.
Also if you wish to add battles between other characters that you feel would be evenly matched feel free to do so. You can bring characters from another comics such as OPM vs. Dragon-ball, marvel vs. DC, Etc.
