Surtur and Galactus. A fully powered Surtur has matched Odin in the past. Every match against Surtur has been a fight to the death for Odin. In Ragnarok, Surtur will kill Odin which will start the fall of Asgard.
On the first occasion, Odin is killed by Mangog, and later revived by Hela.
Galactus would win in a fight against Odin. Odin and Galactus are practically equal in their respective power levels, but they are stronger, more durable, and faster. Odin's only chance at defeating Galactus is if the latter is starved or poorly fed.
While Odin was strong during his prime, Thor was just naturally stronger than him. They don't call Thor the mightiest out of all of the Asgardians for nothing because he is actually a lot stronger than his father in terms of his physical capabilities.
Odin is far and away stronger than CM. He has razed planets himself and defeated Hela multiple times. Not to mention that asgard itself existing is a pretty damn good feat. It takes an extremely powerful force to create a cosmic empire like Asgard.
Odin is Marvel's most powerful Skyfather, which is further confirmation that he is stronger than the Hulk when you take a look at the next entry on this list and what he is capable of against the Green Goliath.
Odin is the most powerful of the Asgardian gods. Possessing the massive energy source called the Odinpower, or Odinforce, Odin's physical abilities are augmented, including superhuman strength, lifting up to 75 tons, superhuman durability, and regenerative powers.
If it came down to it and Odin saw Scarlett Witch as a threat to the Universe and Multiverse and decided to try and take her down, who would win? Odin. Odin could probably kill her but not in a strait up fight.
Based on the analysis of powers, speed, strength, durability, and combat, we can safely say that Odin is stronger than Thanos and outmatches him in almost every aspect. Thanos might be among the most feared villains in the Marvel Universe, but he comes nowhere near when compared to All-Father Odin.
Hercules / Zeus
In fact, he is considered by many authorities to be the physically strongest character Marvel has ever created.
Thor and Odin's hatred of giants.
Odin seals Mjolnir after failing to control its power. When Odin first tried to wield Mjolnir, he couldn't control it due to the God Tempest still retaining its power. The hammer devastated Asgard as it flew out of control. Out of spite, Odin cast an enchantment on the hammer to prevent anyone else from wielding it.
In the poem Grímnismál, it is said that Odin is afraid the two ravens would not come back.
Magni is the elder son of Thor. He had a huge sword, could use the power of lightning, and was really mean. Father killed him.
However, Thor and Loki joins forces with the last Valkyrie and Bruce Banner to escape Sakaar and return to Asgard, where Thor engages his sister in battle while Loki secretly revives Surtur to initiate Ragnarök. Hela attempts to fight Surtur, but is ultimately killed by his Twilight Sword.
Answer and Explanation: According to Norse mythology, Thor dies in an epic battle with a monstrous serpent named Jörmungandr, also known as the Midgard (middle earth) Serpent.
However, as Odin's first born and most loyal and faithful servant, Hela was the original wielder of Mjolnir. Drawing enhanced strength and power from Asgard itself, at one point, Hela was the most powerful warrior in all Nine Realms, unmatched in every way.
Thanos was scared of the ancient one, Odin, and Ego. That's why Thanos didn't show up until infinity war.
Thor is the third most powerful Asgardian in the Nine Realms, surpassed only by his father, Odin, and his older half-sister, Hela. Thor is a Norse warrior god, trained and skilled in the arts of battle, which he has practiced for thousands of years.
All things considered, Scarlet Witch might just be out of her element in this fight, as Zeus is an actual god while she's a person who derived her powers from the Mind Stone. Unlike Thanos, Zeus probably won't be susceptible to Scarlet Witch's bindings and his invulnerability will prevent her from dealing vital damage.
All things considered, Zeus is certainly on Odin's level, so as long as Marvel portrays him accurately, he should be one of the MCU's most powerful characters.
Thor's immense strength, combat prowess, control over lightning, and enchanted hammer, Mjolnir, make him a formidable opponent against Scarlet Witch. In Avengers: Age of Ultron, he demonstrated his ability to resist her reality-warping powers and even physically overpower her.
The World Devourer only fears one incredibly powerful Marvel weapon, the universe-destroying Ultimate Nullifier. There aren't many Marvel gods more powerful than Galactus.
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.
