He's the second strongest Avenger. He is the mightiest. He was able to lift a planet, knock Thanos back yards with one punch, hold back the Hulk with one hand, nearly killed the Beyonder with just his brute strength, etc. Godlike speed: Thor can move beyond warp speed.
Thor / Odin
In the comics, The Norse God of Thunder can destroy planets, control the weather (including summoning lightning bolts), fly through space at the speed of light, and even break adamantium. That's right, Thor could smash Wolverine's metal skeleton if he wanted to. He has beyond class 100 strength.
Thor, son of Gods, has enhanced longevity, augmented by the Golden Apples of Idunn. He also possesses superhuman strength, speed, agility, durability and immunity to most diseases.
In the Marvel Universe, Thor has emerged as the true strongest there is, and has proven to be a cut above the Hulk. Of course, all of this could change in the hands of another story (and writer), but for the time being, Thor has truly earned his reputation as one of the mightiest heroes of the Marvel Universe.
Odin. 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.
Captain America
Cap is one of the few mortals able to not only lift Mjolnir but wield its full power, making him someone who can beat Thor. Assuming the reason for their battle is because Thor is possessed or tricked, Cap would be able to use Mjolnir against him.
Thor is Immortal, Not Invincible
In Avengers: Infinity War, Thor revealed that he was over 1500 years old. It's clear that age doesn't affect him the way it does normal mortals, as with most immortals, he is aging at a slower rate. While Thor will eventually die, it will take thousands of years for it to happen.
The winner of this fight would be Thanos based on his superior brute strength, and raw powers. However, if Thor uses some clever strategies, he could defeat the villain, especially since he has access to more powerful weapons and techniques.
In terms of the power to lift and move large objects, Superman has a stronger edge against Thor. Thor may have been able to move objects that weigh as much as planets, but the Silver Age Superman not only pushed actual planets out of orbit all the time, but even went so far as to move entire galaxies on a whim.
Thor's determination is a weakness in that he keeps throwing himself at an adverse situation to the point of threatening his life. This can be seen by Thor's efforts to lift Mjolnir after losing his worthiness, these many failed attempts drained Thor of his strength.
Thor survives the Time Stone of time. While still aging physically, he retains his youthful appearance far longer than humans, barely changed after Thanos used the Time Stone to age by several centuries, and will only grow stronger the older he gets.
He was shown to depower Thor and cast spells such as the worthiness enchantment as well as break Loki's spell to regain his memories. 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.
He gained many abilities. Godlike strength: Thor has limitless strength and can power himself even more by charging himself with lightning. He was able to bend Captain America's shield, then bend it back perfectly back to shape. He's the second strongest Avenger.
The most powerful Thor variant is Ultimate Thor, who's real name is Thorlief Golmen. Golmen discovers he is the most recent reincarnation of Thor Odinson and begins his journey as the new God of Thunder. This version of Thor was less reliant on Mjolnir as a power source.
Thor: Who wins? Thor wins. Not only is Thor a better combatant and more experienced, but he also can be stronger than Shazam by using Megingjord to augment his superhuman strength.
Absolutely yes. In fact, there are quite a few misconceptions about Thor's abilities.
Thor, the god of Thunder, was undoubtedly the most powerful member of the original Avengers. His power continues to grow in the Marvel Cinematic Universe.
Fat Thor's depression led to his mental and physical decline, which is why he was less powerful in Avengers Endgame than in Ragnarok and Infinity War.
Loki and Thor are both gods and have immense godly powers that make them somewhat impervious to harm, though they can be beaten; they can lose eyes (Thor) and they can die (Loki). If the metric is physical strength, then Thor is easily the winner.
Thor is bulletproof in the comics. So really, absolutely nothing unless those bullets happens to be made of vibranium or pure adamantium.
In Avengers: Infinity War, Thor revealed that he was over 1500 years old. It's clear that age doesn't affect him the way it does normal mortals, as with most immortals, he is aging at a slower rate. While Thor will eventually die, it will take thousands of years for it to happen.
In Thor: The Dark World, he lost his mother and brother (temporarily) to the dark elf Malekith (Christopher Eccleston), and in Thor: Ragnarok he lost his father, his best friends, and his homeworld.
