@Masterofdeath: I'm afraid I still have the same mindset; powerful though they might be, they showed nothing even close to YHVH.
@KingOfAsh: I agree except for Shulk creating a world without gods.
@Masterofdeath: Just one planet?
YHVH blinks universes in and out of existence all the time, literally.
Featherine is stated to be the same way. She is at the the rank of "Creator" where previously where witches were the ones who looked down on humans, she now looks down on witches, who have the ability to create life out of nothing as it is.
Featherine has an uncountable of universes stored of books in her library for her own enjoyment, and she has gone through all of them. The monado means nothing if Shulk can't so much as think about using it against her before she writes down how the battle ends. Since Featherine can control the script of whatever universe she's in, she simply can't lose.
@UltimateHero0406: Any below multiversal die in the first eye-blink.
Considering that YHVH is massively multiversal Arceus loses due to being out-done.
Unless they can demonstrate being able to create and destroy thousands of universes in the span of an eye-blink, they're not touching YHVH.
