Thor: Ragnarok delivered a major blow to the Odinson when Hela destroyed his beloved Mjolnir. Luckily, the God of Thunder learned he didn't need a weapon and could focus his power through his body without a crutch at all. However, when Avengers: Infinity War came along, the Russo brothers decided Thor needed a new weapon and introduced Stormbreaker into the MCU.
While this model is a mix of the Stormbreaker name and the Ultimate Marvel Mjolnir's form, longtime Marvel Comics fans already knew how powerful Stormbreaker both weapons were when each was introduced into the comic books. But, how powerful is this new battle axe-hammer, and how does it compare to Mjolnir?
Is Thor's Stormbreaker More Powerful Than Mjolnir? That is a difficult question to answer, but hints are spread throughout the comics, movies and comments by the creators.
Heading back to the comics themselves, the original Stormbreaker first appeared in Thor #339. The Korbinite known as Beta Ray Bill defeated Thor in a battle to see who was worthy to hold Mjolnir, but the horse-facd alien chose not to accept the weapon. Because of his worthiness shining through all the more, Odin had Eitri forge him a new weapon, and thus Stormbreaker was born.
Stormbreaker from the comics was made from the same materials as Mjolnir -- Uru metal -- making it virtually indestructible. It was the same method that Odin used when he had the dwarves create Thunderstrike years later for Eric Masterson.
If it is, in fact, an exact duplicate, then there is little reason to believe that one is stronger than the other, at least in the comics. But, what about the world of the Marvel Cinematic Universe? As Thor: Ragnarok showed, Mjolnir was not indestructible when faced with the power of a being like Hela (something that has also been proven true in the comics, in all fairness). So, could Stormbreaker be more powerful than Thor's previous hammer in the movies?
Avengers: Infinity War screenwriters Christopher Markus and Stephen McFeely talked about Stormbreaker last year when the movie hit theaters. The two were comparing it to Thanos' Infinity Gauntlet, even stating that it could be even more powerful, which in the end, it proved to be.
Eitri, who created Stormbreaker in the comics and the film universes, also created the Infinity Gauntlet. According to the screenwriters, Stormbreaker could cut through the power of the Gauntlet but not through the glove, explaining that Eitri may have used magic in writing the rules when creating his weapons.
So, with that in mind, does this magic make it more powerful than Mjolnir? Not necessarily. The enchantments and methods used in its creation seem similar, even identical. In Thor: Ragnarok, the Thunder God told Korg that it was made from the special metal from the heat of a dying star, which is exactly how Stormbreaker was crafted in Infinity War.
Ryan Meinerding, Marvel Studios' head of visual development, said in The Art of Avengers: Infinity War that Stormbreaker was almost "too powerful." When going into more detail about the new weapon, he said that it "takes someone incredibly powerful just to pick it up because it's such an unbalanced weapon."
Now, while some observers might automatically assume that makes it more powerful than Mjolnir, that might not be the case. Meinerding's wording makes it sound like the size and build of Stormbreaker makes it harder to handle and control, not necessarily that it's more powerful than the original Asgardian war hammer.
However, something Eitri said does make it sound like it holds a slight advantage. The dwarves crafted Mjolnir, and Eitri is widely considered the most skilled weapon's maker of all dwarves. Eitri called Stormbreaker the best weapon he ever forged, calling it a king's weapon.
While it is the "best weapon" he created, that still doesn't really say whether or not it is stronger than Mjolnir, though. We may have to look at its intent, sinceStormbreaker was created for a very specific reason. It exists to battle Thanos and the power of the Infinity Gauntlet. It is also an ax, so it pierces skin and slices through the power of the gauntlet, but could Mjolnir have also delivered an equally devastating blow?
That remains to be seen, of course, but he has done significant damage to other gods and god-level beings, like Surtur, for example. Also, let's not forget that Hela had a personal connection with Mjolnir, which may have had something to do with its destruction. That may not be the case with other beings.
Both weapons can summon Thor's power of lightning and both can summon the Bifrost. Both are devastating weapons that can lead Thor to victory over almost anyone. Stormbreaker might be slightly more powerful if Eitri is to be taken at his word, but both are truly worthy as the weapon of a god.
