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.
Superhuman Strength: Thor possesses vast superhuman strength, the full limits of which aren't known. However, he is capable of lifting well in excess of 100 tons.
Conclusion: Thor
When it comes to the most powerful character out of Mighty Thor and Thor Odinson, the latter comfortably wins. Thor Odinson has proven himself as the most powerful due to everything that he has been through during his eight MCU appearances.
Odin would win in a fight against Thor because he is simply a lot more powerful and more intelligent than his son. Thor, of course, is the superior physical specimen between the two but is still light years away from his father in terms of his power, intelligence, wisdom, and experience.
That is exactly what the goddess Hel was. Being the daughter of Loki already made her very powerful. However, in her realm of the underworld, this half-decaying goddess was said to be even more powerful than Odin and many other Norse gods.
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.
Hercules / Zeus
He ranks above Thor here because he's technically the stronger of the two. In fact, he is considered by many authorities to be the physically strongest character Marvel has ever created.
Zeus. It should come as no surprise that, in a one-on-one battle of Zeus vs Thor, Zeus would easily triumph.
He gained incredible strength, the ability to fly, and several other powerful abilities that made Hyperion one of Marvel's most powerful heroes. Able to absorb and redirect cosmic energy in various ways, Hyperion could potentially increase his strength beyond Thor's limits.
Self-Sustenance: Eternity is completely free from any physical limitations. Nigh-Omnipotence: As the embodiment of the universe itself, Eternity has almost unlimited power about the universe, only surpassed by The Living Tribunal.
Teleportation: By grasping Mjolnir by the leather thong and rapidly swirling it, Thor can channel energies for the purpose of Wormholes through means of a vortex and in this vortex time has no meaning, which means he and others can pass through it to their destinations instantaneously.
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.
Odin might have had immense power and ruled Asgard in the past, but this cover shows that Thor will surely surpass him. Thor is currently the ruler of Asgard, but his rule has been anything but easy.
While Thor is powerful and his strength is said to be unmatched, he is not strictly immortal like other mythological gods. He is susceptible both to aging and to being killed in battle. Like other Norse gods, he must consume special apples kept by the goddess Idun to keep from aging.
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. Additionally, Thor is more invulnerable than Shazam and has a better understanding and grasp of magical and mystical energies.
Unlike the others, Zeus is not worthy to lift Mjolnir, but through a loophole, he can anyway. If Mjolnir is to enter his domain, Zeus's MCU powers should override Odin's enchantment, meaning he can hold Mjolnir. He may not be worthy, but technically Zeus is the fifth character who can lift Mjolnir in the MCU's Phase 4.
Galactus would win in a fight against Odin.
Superhuman Stamina: His stamina is almost limitless. 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.
Zeus Is More Powerful Than Thor
He's also more intelligent and has more magic and tricks up his sleeve. What is this? Thor might be able to best Zeus in an arm-wrestling match. However, in a fight to the death, Zeus would almost certainly be the victor, especially since he is immortal, but the Norse gods can die.
Determining the strongest Avenger in the MCU is tricky since each brings something unique to the table, and Thor and Hulk are the top contenders in terms of sheer physical strength. However, regarding versatility and range of abilities, Captain Marvel and Doctor Strange are formidable opponents.
Thor is great at close-range combat, too, which is one of Wanda's weak points. Captain Marvel and Captain Carter were able to get in a few blows before succumbing to the Scarlet Witch, and that is because they got close enough to her to do it.
They're both really bad but Zeus had the excuse of being corrupted and was under the influence of Pandora's box which made him act the way he did while Odin was always selfish and manipulative on his own naturally.
Well, it's about even. Hercules' strength is rarely matched. There were times when he even overpowered the Incredible Hulk – a feat that not even Thor could complete. So, when it comes to physical strength, Hercules is the strongest.
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.
