God Emperor Doom:

God Emperor Doom is one of the most powerful beings in all of Marvel comics and can be scaled beyond Outerversal.

God Emperor Doom has been empowered by the race of Beyonders,

We all remember the Pre-Retcon Beyonder right?

Well he was powerful enough to challenge a being who calmed themselves to be the new One Above All,

And the Molecule Man,

And he was retconned to be a child.

An adult Beyonder soloed the Celestial race,

And Infinity, Eternity, Chaos and Order,

And even The Living Tribunal,

Now for God Emperor Doom himself.

Doom turned Johnny Storm into the Sun,

He ripped Thanos’s spine out,

Killed Cyclops who was in possession of the Phoenix Force,

He cracked the Soul Gem,

Fought and destroyed the Infinity Gauntlet,

And the Infinity Gauntlet is Outerversal,

Disintegrate Doctor Strange,

Took over the multiverse with a thought,

And Mr. Fantastic with the same powers of God Emperor Doom could help Franklin Richards and Molecule Man recreate the multiverse,

God Emperor Doom is definitely Outerversal if not High-Outerversal \ Outerversal+.

Hope this helps.
