After gaining the powerful weapon Stormbreaker, Thor becomes the wielder of the most powerful weapon in the universe. Stormbreaker is capable of killing Thanos outright, and only Thor is currently worthy of wielding it.
It's a closer fight if you are talking MCU than the comics. But Thanos stomps Thor either way. Even in the MCU Thanos with no stones stomped Thor, Worthy Cap and Iron Man in a 3v1 fight.
If Thor lands a single attack using Stormbreaker, he would definitely defeat Thanos. Asgard's most powerful weapon is able to instantly decapitate the Mad Titan.
Who would win in an MCU fight: Odin or Thanos? Without the Infinity Gauntlet, Thanos stands little chance against Prime Odin. Odin is stated to be able to shatter the Earth.
While the MCU Hulk was not able to defeat Thanos, his comic book counterparts pose a better chance to make an even fight particularly if Thanos does not wield the Infinity Gauntlet. These two titans in the Marvel Universe seem destined to do battle in some form or another.
The simple answer is no. Yes, Hulk absolutely smashes Thor to the ground with Mjolnir, but, he's holding both Thor and the hammer. Hulk wouldn't have been able to lift Mjolnir by himself, but since the God of Thunder had a firm grip on it as well, he was able to use it as a weapon against his teammate.
While the upgrades give Juggernaut the powers to kill Thanos with ease, it comes at the sacrifice of the former villain, as Juggernaut is abandoned after the Mad Titan is taken down, as no attempts are made to save him as he accelerates through space.
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.
As the glorious battle takes place, Iron Man, Captain America, and Thor join forces to cripple Hela and remove the Twilight Sword from her grasp and use it to eradicate Hela and her corruption from the Nine Realms. Thus, defeating the Goddess of Death without losing an eye.
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.
Can Infinity War Thor with Stormbreaker beat Endgame Thanos without the Infinity Gauntlet? No he cannot. However L&T Prime Thor with or without Stormbreaker would curbstomp Thanos. He's far too strong for Thanos in his L&T Prime.
By most accounts, Superman seemingly outclasses Thor in terms of raw strength, especially in earlier versions of the DC Universe. He's pulled planets, punched people into orbit, and performed all sorts of wild feats of strength.
Stormbreaker has the additional power to summon the Bifröst, allowing Thor to teleport anywhere in the Nine Realms. Screen Rant has identified Stormbreaker as the more powerful of the two, based on this ability, as well as it being a much larger and edged weapon.
At that point, his struggles come almost entirely from his own psychological wounds, which he lacks the tools to properly process. That, and the presumed loss of power from Asgard's destruction, is enough to keep him sufficiently weakened in the final stages of Phase 3, which justifies the poundings he takes.
Infinity War Thor Vs Endgame Thanos People mention Fat Thor and say he was at his absolute peak yet he couldn't take down Thanos thus proving Infinity War Thor would literally stand no chance, but this is just Wrong. Fat Thor didn't use his Awakened powers nor his flight advantage over Thanos.
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.
Thor: Ragnarok gradually reveals the truth about its version of Hela; she is Thor's older sister, and her power seems at least equal to that of Odin the All-Father itself, explaining why she is able to destroy Mjolnir with contemptuous ease.
Virtual Omnipotence: Odin's power was so vast, that when a part of Odin, his dark side bonded with the conceptual entity Infinity, went rogue, it was so large that it could crush planets in its grip as if they were pebbles, his mere limbs stretched as far as galaxies.
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.
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.
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.
Hulk has taken on Marvel gods like Thor before and come out victorious, but Zeus represents a much more powerful opponent. The Olympian easily defeated the Hulk and tested his healing factor in their fight.
After bashing Thor with an entire stone pillar, Juggernaut managed to separate Thor from his hammer – but was unable to lift it as a selfish brute like him was unworthy of its power.
Since Mjölnir can only be wielded by the worthy, Juggernaut has no chance of lifting it. However, that doesn't stop him from using it. In most fights against Thor, Thor throws his hammer at full speed towards Juggernaut, but Juggernaut's mystical force field stops Mjölnir in mid-air.
With enough preparation, Apocalypse would have a surprisingly decent chance at beating a Gauntlet-free Thanos. Apocalypse has trained and fought wars for centuries, mastered many forms of combat and magic, and all of that could very well be enough to topple Thanos, especially if he didn't have the Infinite Gauntlet.
