No one can defeat The One Above All, he is the supreme being in Marvel and a supreme being cannot be defeated, only stalemated. Plus The One Above All is the comic book incarnation of Jack Kirby and also represents the writers so he is quite literally beyond fiction. Can Itachi beat One Above All?
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.
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.
There are numerous incidents within the series that suggest Hulk himself is either the host for the One Below All or may even be the entity itself. This is only half-true, as Hulk is actually the one who manages to defeat the entity, by seemingly killing its host—Brian Banner.
The One Below All is the dark side and a part of the cosmic being known as the One Above All, who is the supreme ruler of the Multiverse and the supreme embodiment of creation and compassion, which would make the One Below All the ultimate personification of destruction and hate.
God (One Above All)
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.
No one or no weapon is more powerful than him. Not the Living Tribunal, not the Infinity Gauntlet, and not Galactus — no matter how many planets he eats. The One-Above-All is also known as Above-All-Others, a name that further clarifies his position in the Marvel universe.
Saying that Saitama could win this fight is pretty ignorant. Imagine that there is a god, and he creates you to have limitless striking strenght. It really doesn't matter how strong your punches are, if that god is truly omnipotent he can decide wheter or not you would harm his body, or even be able to hit him.
Whether that's the Marvel Ultimate Universe or the Marvel Cinematic Universe or the Marvel 616 Universe. The One Above All is more powerful than every other character in any Marvel property. The Hulk is the “strongest” one there is, but that is basically a purely physical strength.
Zeus can be defeated, the One Above all cant be. He is truly omnipotent, and thus he cant be beaten.
So long as the Spirit of Vengeance resides inside them, their human host has the potential to physically live forever. As an added bonus, they remain ageless. In Ghost Riders: Heavens on Fire #6, Johnny Blaze states that since God created the Ghost Riders, only God can destroy them.
One Above All is the creator God of the Marvel Multiverse and is the single most powerful character in the Marvel Universe. This mysterious supreme being hasn't appeared in any of the MCU movies so far but captivated many Marvel Comic fans. One Above All is an omnipotent being and his weapon is love.
With a simple thought, the Beyonder can displace an entire planet, change the rules of physics, and even destroy the entire universe. That's why the Beyonder was presented in Marvel Comics as the most powerful being to ever exist.
Since then, he hasn't lost any of those fights in the series. However, the only fight that came close to testing his true potential was his fight against Garou in the Monsters Association arc of One Punch Man.
Saitama vs cat
[ Still trying to do the math on how, the only thing to ever actually damage Saitama in the series is a cat scratching his face.
Boros. Boros was the first on-screen opponent of Saitama that survived after getting punched, much to his surprise. In his fight with Saitama, Boros was hit with 3 normal punches, a Consecutive Normal Punches attack, as well as the shockwave from the hero's Serious Punch.
The MCU's Eternals introduced the Dreaming Celestial known as Tiamut, who is the only being Galactus has ever been afraid of in Marvel Comics.
Galactus was killed by Thor during the "Herald of Thunder" story arc in Thor (vol. 6) #1–6 (March 2020 – August 2020), and reappeared after a two-year hiatus in Fantastic Four (vol. 6) #45 (July 2022) — the final issue of the event "Reckoning War" — where Galactus is resurrected by his former heralds.
Beyonder is, by far, the most powerful villain in the Marvel universe. He can manipulate and control matter, energy, and reality at a cosmic level beyond far greater than what other cosmic entities can do. He can warp reality to, in theory, simulate any power he wants.
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.
The Presence is the incarnation of the Abrahamic God in the DC Universe. The Presence has the ability to empower various angels, including the Spectre, Eclipso, and Michael Demiurgos.
If none of the versions of Goku can defeat Zeno, then he definitely can't win against TOAA. Until Goku can beat the one who is above all in his own universe, he's not touching any of the ones from other places. He's right.
The One Above All has no eyes in the comics, while his statue in Thor: Love and Thunder has six eyes. Previs of the scene had him with a more comic-accurate design.
