Which Of Thor’s Weapons Is More Powerful

Which Of Thor’s Weapons Is More Powerful

Few weapons in the MCU are as powerful as Mjolnir and Stormbreaker, the legendary weapons of Thor, but does Thor’s axe or Thor’s hammer reign supreme? After Hela destroys Mjolnir in Thor: Ragnarok, Thor gains the mystical axe Stormbreaker in Avengers: Infinity War. Both he and Captain America wielded the Mjolnir of an alternate timeline in the final battle against Thanos, but Thor believed the original Mjolnir well and truly gone. The most recent footage for Thor: Love and Thunder seemed to show his original weapon repaired but now wielded by Jane Foster (Natalie Portman). This has re-opened the age-old Marvel comics debate introduced to the MCU by Infinity War – Mjolnir vs. Stormbreaker. Who would win?


Stormbreaker and Mjolnir are two weapons that answer the call of the God of thunder himself, but there are differences between them. Only those who are deemed worthy to rule Asgard by Mjolnir itself can wield it, which creates many questions about what Jane Foster has been up to since she was last seen in Thor: Dark World. In the first Thor movie, when Odin banishes Thor from Asgard, he sends Mjolnir with him, exclaiming “Whosoever holds this hammer, if he be worthy, shall possess the power of Thor.” Someone must be worthy to lift Mjolnir, but being worthy grants all the godly abilities Thor enjoys. The same rules do not apply to Stormbreaker. Any character matching Thor’s strength could wield his axe and the lightning it emits is channeled from Thor, it can’t generate it.

Audiences have only seen two characters other than Thor wield Mjolnir, Vision picks up Mjolnir in Avengers: Age of Ultron, and Captain America wields it in Avengers: Endgame. There was a joke in Avengers: Endgame in which Captain America is using Stormbreaker and Thor is using Mjolnir, and Thor tells Captain America “No. No, you take the little one” and makes Cap wield Mjolnir, the smaller weapon, suggesting Thor prefers Stormbreaker. This quote is, of course, in jest, but it could provide a minor clue as to which of the two weapons is, in fact, the more powerful. However, since both Mjolnir and Stormbreaker will both feature in Thor: Love and Thunder, it might be that Thor’s axe isn’t the MCU’s most powerful non-Infinity Gauntlet weapon much longer.

Stormbreaker’s Powers In The MCU

Fans have only seen Thor’s mystical battle axe Stormbreaker in action in two films in the MCU, Avengers: Infinity War and Avengers: Endgame, so the information on what abilities it has is limited. In Infinity War, Thor goes to Nidavellir with Groot and Rocket to create a weapon so powerful, it could kill Thanos. On Nidavellir the character Eitri helps Thor make Stormbreaker. Eitri says that Stormbreaker is “a king’s weapon, meant to be the greatest in Asgard, and in theory, it can even summon the Bifrost.” In Avengers: Infinity War, Thor teleports to Wakanda by summoning the Bifrost through Stormbreaker, so it factually has that ability. Audiences can also clearly see during the Battle of Wakanda, Thor throws Stormbreaker at Thanos and it slices through even the power of the six infinity stones, ultimately impaling him in the chest. Also in Avengers: Endgame, Thor cuts Thanos’ head off using Stormbreaker. With these events, it can be deduced that Stormbreaker is powerful enough to overcome six infinity stones and kill Thanos, something Mjolnir couldn’t do.

There are more common abilities for Thor that Stormbreaker possesses. Stormbreaker is able to not only focus, but enhance Thor’s abilities. Thor can use the axe to change the weather, summon lightning, and use it as a weapon. Just like Mjolnir, Stormbreaker allows Thor to fly at super speeds and summon it with his hand. Another similarity between Stormbreaker and Mjolnir is that they are both made of a cosmic metal called Uru, making the axe nigh indestructible. It is safe to say that Stormbreaker cannot be destroyed by anything audiences have seen in the MCU so far.

A power that Stormbreaker lacks is the “worthiness” enchantment of Odin. Anyone physically strong enough to lift and use Stormbreaker can use it. They do not have the power of Thor, so they cannot fly, or summon lightning using it, but can use it as just a powerful battle axe. In Avengers: Endgame, Thanos and Thor battle one-on-one in the climactic finale. Thor summons Stormbreaker, but Thanos intercepts it mid-flight and almost impales Thor in the chest, but thankfully, Captain America intervened. It’s unclear if Stormbreaker will ever receive the “worthiness” enchantment because Odin himself is now dead. Since Thor is seen with Stormbreaker in the trailer for Thor: Love and Thunder, its possible audiences haven’t yet seen its full potential.

Mjolnir’s Powers In The MCU

Mjolnir is the hammer that has almost been like its own character in the MCU thus far. Fans have seen Thor and Mjolnir be as close to inseparable as it gets since the release of Thor in 2011 and Mjolnir has displayed many powers and abilities since then. Unlike Stormbreaker, Mjolnir is specific to Thor. It was bestowed to him by his father Odin, and because of the enchantment that Odin put on it, only a select few people have the ability to even lift the hammer, let alone wield it. Mjolnir can be summoned by Thor, as all he needs to do is reach out his hand and it will come. Mjolnir also gives Thor the power of flight, as we’ve seen Thor lack that ability without the hammer in later films. Thor, using Mjolnir, can also affect the weather and summon lightning as his own personal weapon.

One power that Mjolnir doesn’t have is invulnerability. Though the hammer is made from the enchanted metal Uru just like Stormbreaker, in Thor: Ragnarok, Mjolnir was destroyed by Hela, and fairly easily, too. Thor was unaware that this was even possible, so it is hard to tell who – or what – can destroy Mjolnir. It’s safe to speculate that, based on Eitri’s comments about Stormbreaker, Stormbreaker cannot be destroyed as easily as Mjolnir was.

Trailers for Thor: Love and Thunder show Jane Foster wielding a repaired Mjolnir. Its appearance has changed a little, with the shattered fragments joined by Kintsugi-like glowing blue energy. Thor’s hammer appears to respond to Jane now, flying to her hand instead of his. She’s also shown with lightning crackling over her skin as she wields the worthy-only weapon with ease. Since Jane Foster is human and as far as audiences know lacks any kind of superhuman abilities of her own, it appears Mjolnir’s lived up to Odin’s initial promise and bestowed her with Thor’s power.

Why Stormbreaker Is Thor’s Most Powerful Weapon In The MCU

Thor Stormbreaker Mjolnir

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. Stormbreaker certainly appears to be more powerful in the movies, as it had the ability to impale and kill Thanos, while also overpowering the might of the six Infinity Stones. Mjolnir was destroyed by Hela (one-handed), meaning that it’s breakable on some level, whereas it seems that Stormbreaker cannot be so easily shattered.

The last thing to consider – and what really gives Stormbreaker the edge out of the two – is that Stormbreaker can summon the Bifrost. This means that Thor has the ability to instantaneously travel to virtually anywhere in the Nine Realms while holding the axe. That ability is something he cannot do with Mjolnir. It seems Thor enjoys both weapons; after all, he seemed very happy to find out he was still worthy in Avengers: Endgame. But as mentioned before, it appears that he prefers Stormbreaker out of the two, and rightfully so, because it gives him the best advantage over his enemies – in ways that Mjolnir doesn’t.

Will Mjolnir and Stormbreaker Be Enough To Match The Necrosword

Powerful as they are, Mjolnir and Stormbreaker may have to step aside for a new MCU’s-most-dangerous-weapon when Thor: Love and Thunder releases – All-Black the Necrosword. Jane Foster and Mjolnir weren’t the only powerhouses revealed in the Thor: Love & Thunder trailer. Gorr the God Butcher, harrowingly brought to the screen by Christian Bale, and the deity-slaying Necrosword also made their debut appearances to eager MCU fans.

In the comics, Gorr the God Butcher wields a feared weapon whose full name is All-Black the Necrosword, or The Godslayer. It is an immensely powerful sword created by Knull, God of the Symbiotes, and is in fact the first Symbiote ever created. It’s made from literal living darkness and tempered in the fires of a dead Celestial’s power. While Symbiotes haven’t made it into the MCU outside of Venom’s franchise-hopping post-credit scenes, and Knull remains exclusively on the page, Celestials were shown in The Eternals to be among the most powerful entities in the multiverse. If Gorr’s MCU weapon is anything as powerful as Gorr’s Celestial-killing symbiote All-Black the Necrosword, Thor could be in trouble no matter which weapon he wields.

Necroswords already existed in the MCU, although they’re not referenced out loud. They’re the obsidian blades used by Hela in Thor: Ragnarok. It’s not known yet if Gorr’s Necrosword is one of those wielded by Hela, or if this is an entirely new weapon that will retcon that particular piece of MCU lore. Either way, trailers for Thor: Love and Thunder contain many scenes of Gorr the God Butcher using his Necrosword to, among other things, vaporize an entire planet. For context, in Infinity War, it took Thanos visible effort despite possessing multiple Infinity Stones to pull a small moon out of orbit. Regardless of its origin, the MCU’s Necrosword has already shown itself to be an immensely powerful weapon, one fit for a character with the moniker of God Butcher. The upcoming Thor movie might render the Mjolnir vs. Stormbreaker debate irrelevant- it doesn’t matter which is more powerful if neither can match the Necrosword.
