Odin is basically Thor and all the other Asgardians rolled into one—though he's even wiser, more experienced, and minus one eye. As the default King of Asgard, Odin is easily the most powerful being in his realm.
Portrayed by Anthony Hopkins, Odin is the powerful ruler of the Nine Realms who has sworn to protect every kingdom under his rule. With Odin still ruling Asgard, Thanos would have easily been stopped had he made a play for the Infinity Gauntlet.
So while Zeus' best feat is defeating a mountain-sized monster, Odin's best feat is defeating a monster as big as nine worlds. Odin outclasses Zeus in intelligence, versatility, strength, and weapons. Zeus simply can't compete. The winner is Odin, All-Father of the Æsir.
If he was relatively calm Odin would probably engage the Hulk physically to underline the difference in power between them. Odin would crush hulk! Odin is the most powerful being in the nine realms outside of cosmic entities.
Odin stands a good chance at defeating a moderately-fed Galactus. Odin has been stated to be equal to a moderately-fed Galactus. Though Galan did withstand a powerful headbutt from Odin. The Devourer had just consumed one planet before that.
Odin would beat thor a hundred times before it ever came down to a fight, but if it ever somehow came down to a legit fight, thor would beat his old man.
The Olympian and the Asgardian are evenly matched in terms of both strength and durability. For comparison, both Thor and Hercules' durability and raw power pale in comparison to the likes of Zeus - a low-key but crucial Thor: Love and Thunder spoiler for any future outings of the Olympians.
Odin has beaten Hela and had his son resurrected many times, and she has yet to succeed in taking retribution. These days, Odin is no longer the King of Asgard and no longer has the Odinforce, so, if Hela wanted revenge on the old man, now would be the time.
But then how did Odin beat Darkseid? WIZ: Odin tore the 4th world, the home of the gods, out of the divine sphere, thus Darkseid was no longer a higher dimensional being, just one god in one universe. This made it possible for Odin to kill Darkseid.
Originally Answered: Who would win, Dormammu (MCU) or Odin (MCU)? Well it depends what age Odin is. The Odin we see in the movies isn't nearly as powerful as prime Odin. However even Odin in his prime would still have a tough time against Dormammu.
Mjolnir was crafted from a nugget of Uru, a powerful nigh-invulnerable Asgardian metal. Additional enchantments placed upon it by Odin made it virtually indestructible.
Now Odin did tell Thor he was stronger then him (Odin) which some interpret as Odin meaning Thor is stronger than Odin cause Thor now has his fathers power plus his own. But we have to remember two things. Odin himself said Mjølnir only channeled Thor's power, Thor just needed to learn to use it naturally.
For those who are having trouble with Odin in Final Fantasy VII Rebirth: he's weak against Disempowerment and Poison! -You can indefinitely delay getting hit with Zantetsuken if you time your Debraves, Defaiths, ATB attacks and Poison magic correctly.
In a Zeus vs Thor scenario, Zeus would probably end up the victor, but the same goes for his son, Hercules. Technically speaking, he's only a demigod, but, if any biceps could outsize Thor's, then it is the Herculators.
When Mangog threatened Asgard anew, Odin led his forces against him but ultimately perished at Mangog's hands. However, when the Olympian death god Pluto tried to conquer Asgard, Hela restored Odin to life to stop him.
Without the Infinity Gauntlet, Thanos stands little chance against Prime Odin. Odin is stated to be able to shatter the Earth. And he turned Frigga into stars. He has devastated while worlds, laid waste to kingdoms and destroyed demons and monsters.
I think Odin wins this fight with Mid to High difficulty. He is a powerful Multiversal+ Immortal God who has a whole bunch of OP feats and abilities that places him well above the likes of Ghostrider.
Odin wipes the floor with Thor every time they fight. So the fact that Thor was able to hold his own against Zeus speaks volumes, and I think is good enough evidence to say that between Odin and Zeus, Odin is more powerful than Zeus, perhaps even more than just "Slightly more powerful."
Unable to kill his own daughter, Odin defeated Hela and imprisoned her using his own power to keep her at bay in another realm for eons. During this respite, Hela attempted to escape imprisonment in Hel and was near successful.
Now, to the real question, can MCU Captain Marvel defeat Odin? HELL TO THE HELL NO. The All-Father was able to imprison Hela for at least an ENTIRE MILLENNIA. The same Hela that massacred the Valkyries but Brunnhilde.
