This would go just like full power doom (with Galactus power) vs the Beyonder.
Wave after wave of limitless energy until Galan falls.

If its Eternity level I'll just consider the fight
Ion vs. Eternity thanks And in that case... Eternity wins.
Ion has the power of the center of the universe... Eternity is the universe.
In all other cases... Ion wins.

"There is no writer to purposely ignore a character's natural ability just because it suits the story."
"in some cases because the writer knows that Character A will dominate Character B easily and refuses to allow this to happen for the sake of the story."
Actually, Ion WAS the power of the battery instead of the other way around.
He could exist outside of reality easily.

ion achieved virtual godhood in this state, and though galactus is very powerful he wouldnt be able to exert himself as long as ion could.....ion wins 8/10
Both Fp Galactus and Ion are a unity with the Universe.
So if they were one with the same universe (the one they would fight in) than both would die, because if either of them die than the Universe will colapse.
