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.
In a battle between the two, it's unlikely Thanos would come out on top. He may be a powerful Titan, but against an Asgardian like Odin, whose power was essentially infinite, there is no way he could have won.
Thanos Feared an Attack From Odin and He Might Have Been Planning One. However, it's possible that Odin kept his kids in the dark because he was preparing to take on Thanos all along.
Odin was too old to follow potential threats as powerful as Thanos, and the unfortunate circumstances around his twilight years meant that he couldn't contribute much in the fight against the Mad Titan. Related: MCU: How Much Odin Knew About Thanos (Could He Have Stopped Him?)

Could Odin beat Zeus?
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.
As Skyfather of Olympus, Zeus wields power comparable to Odin, whose wrath Thanos has withstood but not bested. At the same time, Zeus cannot truly die. While the most powerful of Olympians can be badly wounded or even dismembered, he can never actually pass on into oblivion.
A significant part of Thor's trauma stems from his failure to kill Thanos in Avengers: Infinity War, leading to the Mad Titan's devastating Snap. Thor had Thanos comfortably beaten, yet did not strike a blow at his head, instead curiously deciding to sink Stormbreaker into the great Titan's chest.
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.
Although he is an extremely skilled marksman, Clint Barton is often considered to be the weakest member of the team seeing as he's just a regular guy with a bow and arrow. That certainly means that Hawkeye one of the weakest Avengers.
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.
Thanos would probably decimate Deadpool over and over, but with the merc's regenerative ability it would only be a matter of time until Deadpool strikes the final blow and wins this bout.
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.
He transported Thor back to Asgard where Odin took this as an act of war and fought an extremely destructive battle with Thanos. Even upon learning the truth, Odin did not thank Thanos for his reluctant altruism, but told him to leave and never return.
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.
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.
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.
While Thanos is usually the victor, it's generally down to him using superior tactics and technology, rather than simply possessing greater physical strength. However, when the two clashed in Infinity War, Thanos beat Hulk in a wildly one-sided fight.
Superman has beaten everything the Multiverse has thrown at him and always come back for more. He's faced Thanos's type many times and always won. Superman is vastly more powerful and skilled than Thanos. It wouldn't take him long to realize how dangerous the Mad Titan was and once he did, he'd take the kid gloves off.
I think, quite simply, he underestimated both Stormbreaker and this more godly Thor. He had the power to simply snuff Thor from existence or fire a beam that nothing in the universe could stop. Or anything else he could imagine.
As such, Zeus decides to grant the Hulk's request to beat him to death in hand-to-hand combat. The Hulk's first blow sends Zeus crashing into a nearby building. Zeus then returns this with an even more powerful blow. The ruler of the Olympians than overpowers the Hulk, and ultimately knocks him off Mount Olympus.
In a fistfight, Hercules. In a fight with weapons, Hercules. In a contest of cunning it's hard to say. Mythological Loki got himself in trouble more than he got himself out of it, and hercules has enough brains to solve several of his labors.
