Mjölnir (commonly written without
diacritics as Mjolnir) and Stormbreaker, in the
Marvel Cinematic Universe, are sentient enchanted
weapons of choice used by
Thor, the
Norse god of Thunder. Both are
melee weapons and were created out of Uru metal forged with the heat of a dying star in the Dwarven kingdom of
Nidavellir, with the assistance of the dwarf king and master weapon-maker
Eitri. Mjolnir is a
hammer
A hammer is a tool, most often a hand tool, consisting of a weighted "head" fixed to a long handle that is swung to deliver an impact to a small area of an object. This can be, for example, to drive nails into wood, to shape metal (as w ...

, so that only those the hammer deemed "worthy" are capable of wielding or even lifting it. Stormbreaker is an
axe, and although it does not have such a worthiness enchantment, its power is such that a mere mortal attempting to wield it would be driven mad.
Mjolnir first appeared in the post-credits scene in ''
Iron Man 2'' (2010), and has appeared thereafter in every film featuring Thor except for one, those being ''

Conceptual history
Mjolnir debuted in print in the
Marvel Comics title ''
Journey into Mystery'' #83 (Aug. 1962), being the means by which physician Donald Blake transformed into thunder god
Thor Odinson (by striking it on the ground). The first use of the hammer's name was in the "Tales of Asgard" feature in ''Thor'' #135 (Dec. 1966) in a story by Stan Lee and Jack Kirby. The weapon's origin is eventually revealed in ''Thor'' Annual #11 (1983), with another version presented in ''Thor'' vol. 2, #80 (Aug. 2004).
Mjolnir's origin in the Marvel Comics continuity mirrors the original
Norse legend. The hammer is created when

Sif as part of a cruel jest, and, when threatened with violence by Thor, promises to fetch replacement hair from the dwarf smiths. Loki commissions the hair from the Sons of Ivaldi, and the obliging dwarves create the hair and other gifts for the gods. Loki is convinced that no one can match their workmanship, and challenges a dwarf named
Eitri to make finer treasures. After creating some other magical items, Eitri begins work on a hammer. Loki panics, fearing that he will lose the wager, and transforms himself into a moth to bother Eitri (in the original myth, Loki becomes a

and stings Eitri's assistant). As a result, the hammer's handle is shorter in length than Eitri intended, meaning that it could only be wielded one-handed. Despite the error, the Norse gods consider Eitri to have forged the greater treasures, and Loki loses the bet.
In a 2002 documentary with
Kevin Smith, Lee says his brother and co-creator
Larry Lieber originally referred to Mjolnir as the "Uru Hammer".
Writer Roy Thomas eventually changed the name of the hammer to the mythologically correct name of "Mjolnir" but maintained the Larry Lieber concept of it being composed of fictional metal "uru".
Film design
Visual Development Supervisor Charlie Wen was tasked with designing Thor's appearance for the films, and focused on mixing elements from the comic books with Norse mythology, "trying to maintain the Norse side of things" as much as possible.
The first design element that Wen attempted was Mjolnir, for which Wen created a number of possible alternatives, incorporating designs including "the traditional Thor hammer with the short handle as well as the Ultimates versions", from which the one director
Kenneth Branagh chose "was the most traditional one".
In a 2018 interview with
Jimmy Kimmel, Thor actor
Chris Hemsworth revealed that he has kept a number of the prop hammers created for the film.
The concept artist tasked with designing the MCU version of Stormbreaker, Ryan Meinerding, decided to deviate substantially from the design of Stormbreaker used in the comics, feeling that "the original Stormbreaker looked a bit too much like the original Mjolnir".
Consequently, Stormbreaker "more closely resembles the Mjolnir from the
Ultimate Marvel run than the original Stormbreaker hammer bestowed upon Thor's rival turned ally
Beta Ray Bill".
Meinerding intentionally made Stormbreaker comparatively oversized and overpowered, to convey that the wielder of the weapon must also be someone incredibly powerful.
Powers and characteristics
Both weapons can be summoned by Thor, and will return to his hand after being thrown.
Both weapons also enable Thor to fly, and to channel his power to summon lightning.
Stormbreaker has the additional power to summon the

'' has identified Stormbreaker as the more powerful of the two, based on this ability, as well as it being a much larger and edged weapon.
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.
Appearances
Initial appearance
Mjolnir is first seen in the MCU in a
post-credits scene in the 2010 film, ''
Iron Man 2'', in which
S.H.I.E.L.D. Agent
Phil Coulson reports on the hammer being found at the center of an impact crater in the New Mexican desert. Locals try to move it, even using a rope tied to a pickup truck, without success.
Its appearance there is explained in ''
Thor''. The hammer is first seen in Odin's vault, along with other powerful artifacts. An adult Thor preparing to inherit the throne of Asgard wields Mjolnir in battle against

on
Jotunheim. After Thor re-ignites an ancient war between Asgard and the Frost Giants, Odin banishes him to
Earth, stripping his son of his superhuman abilities and enchanting Mjolnir so that only those worthy are capable of lifting it. Odin also sends Mjolnir to Earth, where a crowd of humans gather in an effort to lift the hammer, attracting the attention of S.H.I.E.L.D. Thor eventually finds Mjolnir but is himself unable to lift it until he later proves his worthiness by sacrificing his life against the

artificial intelligence, comparing him to an elevator that would continue to work if Mjolnir were placed inside.
Mjolnir also appears in a June 2014 poster advertising the upcoming film, ''
Ant-Man'', with the protagonist in his miniaturized form standing on the hammer, though it does not appear in the film itself.

Hela escapes from her prison. Thor throws Mjolnir at her but she catches and destroys it. Thor's exploration of Hela's origins reveals to him that Mjolnir was originally her weapon.

. Thor helps Eitri restart the damaged forge to heat the ore, and nearly dies while trying to create it, but before its completion. Eitri declares that Thor "needs the axe" to survive, so Groot hastily brings together the two pieces that make the head of Stormbreaker and cuts off his own arm to serve as a handle; Thor is then healed by the completed Stormbreaker. Stormbreaker is capable of conjuring massive lightning attacks, allows Thor to fly, and serves as a two-handed offensive weapon capable of withstanding attacks from the
Infinity Gauntlet with all six Infinity Stones.
Thor then uses it to defeat the Outriders in Wakanda, and to attack Thanos, overcoming a counterattack by the Infinity Gauntlet and seriously wounding Thanos with a blow to the chest. Nevertheless, Thanos is able to use the gauntlet to
snap away half of all life, and then teleport away.
Using Stormbreaker and recovering alternative timeline Mjolnir
In ''Avengers: Endgame'', some weeks after the snap, Thor uses the axe to decapitate Thanos on the
Garden. However, at this point the Infinity Stones have been destroyed by Thanos, preventing the snap from being undone.

Restoration of the broken Mjolnir
In January 2022, it was reported that promotional artwork for the forthcoming fourth Thor movie, ''
Thor: Love and Thunder'', showed that the destroyed version of Mjolnir had been remade (albeit with visible cracks), and was now being wielded by a worthy Jane Foster. In the film, a flashback reveals that years earlier, Thor unknowingly enchanted Mjolnir to protect Foster. When Foster is diagnosed with
terminal cancer, she researches the possibility that Mjolnir gives its wielder enhanced strength and stamina. She travels to New Asgard in search of the remnants of Mjolnir, which reassembles itself in Jane's presence and proclaims her worthy, surprising Thor when he meets her again as the new wielder of the hammer. Foster, thereby having the power of Thor, uses the alias of Mighty Thor and wields the reconstructed version of the hammer in battle against
Gorr the God Butcher and his forces, and against soldiers of Zeus while visiting Omnipotence City. The reconstructed hammer, when launched from its wielder, can separate into its fragments to hit multiple targets at once before reassembling. In one comedic moment, Thor tries to summon Mjolnir, but Stormbreaker enters the room, with Thor reacting as if Stormbreaker were jealous.
Thor, Foster, and Valkyrie pursue Gorr to the Shadow Realm, where Foster sees ancient drawings that depict Thor's battle-axe Stormbreaker as a way to summon the Bifrost to enter the realm of a godlike celestial called Eternity, who can grant Gorr's wish to destroy all gods. Foster deduces the trap laid out by Gorr and throws away Stormbreaker to prevent Gorr from accessing it, but Gorr overpowers the group and threatens to kill Foster, forcing Thor to summon Stormbreaker back. Gorr successfully steals Stormbreaker and injures Valkyrie before a weakened Foster collapses. Foster learns that use of Mjolnir is actually exacerbating her cancer by draining her life force. In the final confrontation with Gorr, she nevertheless uses Mjolnir to destroy the Necrosword, at the cost of her own life. Gorr succeeds in using Stormbreaker to reach Eternity, but Thor persuades Gorr to use his wish to revive his lost daughter, Love. Thor once again takes possession of Mjolnir following Foster's death. In the end, Thor adopts Love, who has been restored from death by Eternity, and Thor gives Love Stormbreaker while reclaiming use of the restored Mjölnir and wielding it for himself.
