Cosmic Armor Superman- simple fact since the character transcends the page theme-selves.
The Great Evil Beast- GEB was equaled to the Presence, no one else could have matched him
Lucifer/Michael- He is the will of the Presence personified. His equal being Michael. This is the same man that took a Michael’s point blank explosion to the first with no damage, then used said energies to make his own Multiverse with all the aspect of concepts. Michael himself knew if he were to let himself die in the main Multiverse, he would have ended everything. Michael himself kept the Multiverse from destruction by holding everything together.
Mxy- This is the same being that destroys and recreates the Multiverse once a week. He transcends all stories. To Mxy, there is no such thing as alternate verses, hyper time. Mxy is one in the same all throughout. The only reason he's lower than Lucy/Mikey, is because those 2 are the Presence 2 parallels.
Doctor Manhattan- He hasn’t done much that puts him above Mxy, even when the story said so. Anything he’s done, Mxy has done them a 1000 times over.
Beyonder/Molecule Man- I always saw the 2 of them as Mxy lite. They might give Mxy trouble if he’s playing around, but the second he gets serious, they loses hard. As for MM, I am using his Secret War appearance since he’s been retconned far to much.
Multi Eternity/Protege
Thanos With Rwgualtor
Scathan
The only ones I would say I’m not 100% sure off are the last three since I don’t follow their stories like I do the DC side.
