Although Stormbreaker and Mjolnir have very similar properties and powers, Stormbreaker is the most powerful weapon wielded by Thor so far. The obvious reasons are that Stormbreaker is the physically larger weapon out of the two, and not to mention that it is an axe, which could well be more dangerous than a hammer.
Overall, though, Stormbreaker seems to have the edge over Mjolnir once again. Strong enough to open the Bifrost, reach Eternity, and manipulate storms the same way Mjolnir can, Stormbreaker's powers are greater than that of the mythical hammer.
Mjolnir is Thor's signature weapon in both mythology and the MCU, but he has since grown accustomed to wielding the powerful Stormbreaker. While Thor's hammer is a powerful force, it isn't the most powerful weapon in the entire franchise.
Despite Thunderbolt being a stronger weapon than Mjolnir, and even Stormbreaker, the Infinity Gauntlet is still the most powerful weapon in the MCU, at least when powered by the Infinity Stones.
The Leviathan Axe is Canonically More Powerful than Mjolnir.
While it is true that the hammer would have been an incredible asset for the player, it cannot be wielded or even picked up by Kratos (nor Atreus) for several reasons.
Hela is a worthy competitor to Kratos in every way. She's ruthless and has superhuman strength, untouchable speed, relentless stamina, and a healing factor. However, she doesn't have experience in killing all the gods. Hence, the Ghost of Sparta would certainly stand victorious against her.
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.
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.
In a Zeus vs Thor scenario, Zeus would probably end up the victor, but the same goes for his son, Hercules. Technically speaking, he's only a demigod, but, if any biceps could outsize Thor's, then it is the Herculators.
And Mathaudhu can cite documentary sources to back him up. For example, Marvel – which publishes the Thor comics – issued a “Thor's Hammer” trading card in 1991 that states Mjolnir is made of Uru and weighs precisely 42.3 pounds. That's lighter than a herd of 300 billion mice, much less a herd of 300 billion elephants.
Another version appears in the seventh episode, which Thor uses to fight against Captain Marvel. For unexplained reasons, Thor remains the only one able to lift the hammer in this universe despite Odin never shown enchanting it with the "worthy" spell.
Captain Marvel is one of the strongest Avengers; so much that she is one of the few characters who can lift Thor's hammer Mjolnir without being worthy.
Thor doesn't always save the day in Marvel Comics, and some of his biggest losses include falling to Thanos and Gorr the God Butcher. Thor: Love And Thunder revisits Thor after he has lost everything, including his home in Asgard, his brother Loki, and his sense of place in the universe.
There are very few powers that Mjolnir grants him, but it does seem to amplify his connection to the Odinforce at all times, and accordingly, powers him up. Still, most of Thor's powers can be performed without Mjolnir.
Both weapons also appear to have a degree of sentience, with Stormbreaker apparently being envious of Thor's affection for Mjolnir, a characteristic director Taika Waititi attributed to the handle being made from the arm of the adolescent Groot, and carrying over some of that character's moodiness at that age.
Hela Was Worthy Enough to Destroy Mjolnir
Many people other than Thor have wielded Mjolnir, including his sister Hela. But the impactful scene in Thor: Ragnarok depicts Hela catching Mjolnir in mid-air before then crushing it to pieces. Odin previously told Thor the power of the Uru metal had no equal.
Mjolnir was forged by a dwarf named Sindri. While he was creating it, Loki, the trickster fire god, disguised himself as a fly and attempted to interfere with Sindri's work by buzzing around him. As a result, Mjolnir's handle was unusually short.
Throughout God of War Ragnarök, Kratos blocks, deflects, redirect, and stops Mjölnir dead in its tracks, however. This is no minor feat and should clearly speak to Kratos' abilities and strength. Unfortunately, he never wields Mjölnir in the same way that Thor does, something fans surely would have enjoyed seeing.
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. It was shown multiple times throughout comics.
Why is Zeus the strongest god? Zeus is the strongest of the gods in the Ancient Greek religion because he has both power and intelligence. He is able to ensure that he is not replaced by another, more powerful deity. He is also able to ensure the allegiance of many other gods by giving them rights and privileges.
So Thor took on Zeus himself and handled himself very well against the Greek All-Father.
4 Saitama Can Literally Beat Kratos With A Single Punch
Saitama does not get excited about battle anymore, and that is because he has become the strongest known being in the universe. Like Kratos, Saitama possesses inhuman strength and endurance, but unlike the God of War, he has unparalleled speed and reflexes.
7 Her Glaring Weakness
For Hela, it's her cloak. Without it, she can be reduced to her true form, that of a half-dead woman. One portion of her body remains alive and well, but the only half is no more than a rotting corpse, unable to move or do anything.
The Hulk's strength has no limits. While Kratos' rage seems to be the source of a lot of his power in battle, The Hulk could easily match this and more. The more angry Hulk gets, the stronger he becomes, and there's no way Kratos could cope with this on any level.
