The One Above All is the ultimate source of life and creation and the architect/creator of the Multiverse and everything that exists. The One Above All has stated that its "only weapon is love", which was further stated by the Watcher.
The Beyonder and the One-Above-All are godlike beings in the Marvel Universe, but one is definitely a more supreme being. The Beyonder and the One-Above-All both have a decent claim to being the most powerful character in the Marvel Universe.
While the two company's heroes are pretty evenly matched in some places, DC's are just too much for Marvel. Beyond the fact that DC's heroes are overall more powerful, they have numerous advantages. From magic-users to Kryptonians to the Flash Family, Marvel can't match DC's power.
2. Lucifer Morningstar. As an archangel and the son of The Presence, it's easy to see why Lucifer Morningstar ranks second on this list of most powerful DC characters. After rebelling against the Kingdom of Heaven, Lucifer was cast out and forced to rule over Hell.
One Above All was one of the many victims of Thanos in his eternal quest to please Death. He was obliterated along his fellow Celestials by Thanos when he stabbed Black Bolt to death in order to use his destructive voice as weapon.

Nothing can ever beat The One Above All. Which probably answers the, “Will he appear in the MCU?” question. There would probably never ever be a reason why The One Above All would need to show himself within the MCU. Unless the entire universe was as the risk of being destroyed, it seems very unlikely.
Thanos defeated the One Above All in The Infinity Conflict storyline. Thanos used the so-called “Astral Regulators” and their powers to bring an end to the ultimate creator.
In the world of DC Comics, three heroes reign supreme: Superman, Batman, and Wonder Woman. The trio, commonly referred to as the DC Trinity, packs a powerful punch.
Marvel's Eternity is very similar to DC's Kismet, in that he represents an entire universe and is virtually omnipotent within this realm.

Only he has the power to command the Judge of the Multiverse, the Living Tribunal to which the latter yields. Above all (pun intended), he is supremely powerful as he is infinitely above all of creation in the Marvel Omniverse.
Yahweh was one of the gods of Earth, but his true origin varies from one account to another. Yahweh was part of a group of life-forms that existed before the Multiverse, and who were the only sentient life at that point.
When Bruce Banner fell victim to the Gamma Bomb, he opened a Green Door and was infused with the One Below All's power, becoming the Hulk.
Unleashed on the world, the One-Below-All began possessing others who had been transformed by gamma energy. The Hulk and Gamma Flight were forced to confront the One-Below-All in its own dimension, with the Hulk seemingly beating him back with a massive blast.
The One-Above-All
As one might expect, the One-Above-All's powers are infinite and unparalleled by any being. While the One-Above-All could surely destroy Captain Marvel at any moment, the entity largely remains out of the action.
Zeus can be defeated, the One Above all cant be. He is truly omnipotent, and thus he cant be beaten.
Wanda was considered to be the Nexus Being of Earth-616, but there were still forces far more powerful than her. Perhaps the most obvious character that was more powerful than the Scarlet Witch was the One Above All, who acted as the "god" of the Marvel universe.

In short, Black Adam should be Shazam's equal, but some of his powers are beyond Billy Batson's abilities. Black Adam also has allies that help him overcome entire squads of superheroes. Then, Black Adam has a lot of combat experience, while Shazam is, in fact, a child.
Zeus. It should come as no surprise that, in a one-on-one battle of Zeus vs Thor, Zeus would easily triumph.
