-- Mjölnir's enchantment


Dwarves from Thor Vol 2 80

Dwarves forging "Mjolnir"

Mjölnir (literally, "that which smashes") is the hammer wielded by Thor, the Norse god of thunder.[1]

Ages ago, an unimaginably powerful cosmic storm called the God Tempest approached Asgard. Called the "Mother of Thunder," the storm possessed the power to knock planets out of their orbit and make black holes shake. Odin, chief of the Norse gods, battled the storm for many days when it threatened Asgard. Once the storm was weakened enough, Odin defeated the God Tempest by trapping it into a chunk of Uru that was given to him by the Dwarves of Nidavellir as a gift.[2]

From the Uru, Odin ordered the Dwarves of Nidavellir to forge Mjölnir.[3] The blacksmiths Eitri, Brokk,[4] and Buri[3] needed to use the tremendous heat of a star to get the forge hot enough to smelt the Uru. The hammer was completed in seventeen weeks.[2]

In the process the star exploded and almost took Midgard with it; that event may explain the extinction of the dinosaurs, about 65 million years ago.[3]

When Odin first tried to wield Mjölnir, he couldn't control it due to the God Tempest still retaining its power. The hammer devastated Asgard as it flew out of control. Out of spite, Odin cast an enchantment on the hammer to prevent anyone else from wielding the hammer. The hammer was stored away where it sat for untold ages where the God Tempest would eventually die, but its power would remain inside Mjölnir.[2]

Although powerful in and of itself, the hammer also received several potent spells from Odin, who slew the Frost Giant Laufey with it.[5]

Much later, Mjölnir was bequeathed to Thor, after he proved himself worthy through several trials.[6]

With few exceptions, Thor has carried Mjölnir throughout his adventures. Thus, the history of Mjölnir follow the history of Thor. Although Asgard was destroyed in Ragnarök, Thor, and thus the hammer, survived.[7]

After Nick Fury told him an undisclosed secret, he lost his ability of wielding Mjölnir.[8] It was later revealed that the secret was "Gorr was right", that gods, being destructive, petty and vindictive, did not deserve the love and worship of the mortals they protected.[9]

Later, a woman became Mjölnir's new wielder and the new Thor.[10] She was eventually revealed to be Thor's ex-lover Jane Foster.[11]


Mjölnir itself is already extremely durable and nigh invulnerable like the Earth metal adamantium or the Olympian metal adamantine, and combined with the various enchantments placed upon it by Odin, is for all intents and purposes, indestructible. It has survived heat as extreme as the heart of suns, blasts powerful enough to destroy planets, and it has contained energy sufficient enough to destroy an entire galaxy and even energy sufficient enough to destroy one fifth of the universe. Mjölnir also grants its user, such as Thor, countless mystical attributes and powers such as manipulation of the fundamental forces of the universe such as the electromagnetic spectrum[12], gravity[13] etc. Mjölnir can be used both offensively and defensively. Thor often uses the hammer as a physical weapon, with almost nothing being capable of withstanding a hammer blow or throw. It has been described as impacting with sufficient force to "destroy mountains"[14] and has proven capable of shattering the armor of a Celestial.[15] A rare exception is primary adamantium. [16]

Mjölnir was classified by the Initiative as an Omega Class Weapon, at the level of the Tactigon.[17]

A few other examples of the countless abilities Thor has shown with Mjölnir are:

  • Worthiness Enchantment: This enchantment surrounding Mjölnir prevents it from being wielded by anyone save those who have been found worthy. Thus far, this includes Thor, the Red Norvell, Buri, Bor, Odin, Beta Ray Bill, and Captain America. To anyone else, Mjölnir cannot be lifted from the ground nor wrested from Thor’s grip.[18] Those who are deemed worthy are able to wield Thor's powers. Captain America said "I've never wielded such limitless power before!"[19] "It's almost intoxicating!"[20] As the true master of Mjölnir, Thor can also will unto others the ability to wield the mystical hammer, bypassing the worthiness enchantment, and also empower them with his own godly abilities. As long as he is alive, no one but himself is able to wield the hammer.[21] The enchantment is so powerful that even with the hammer cut in half, it's still in effect.[22] However, after Nick Fury whispered to Thor "Gorr was right" during a fight,[23] Thor not only lost the ability to wield Mjölnir, but the very nature of the enchantment was changed to prevent Thor, the Warriors Three, or Odin himself from lifting it, while allowing the new Thor to pick it up as the inscription changed to "if she be worthy". Although Loki was found to be worthy to wield it for a short period of time after being hit by the reversion spell of Scarlet Witch and Doctor Doom which turned him good[24], he later lost that ability after another reversion spell was cast that returned him to his normal self.[25]
  • Mystical Link: Mjölnir obeys Thor’s commands as though it were alive[26] (it was later revealed that the hammer does indeed have its own sentience)[27], and if Thor’s will is strong enough, the hammer can pass through nearly any barrier to reach him should he so choose; Mjölnir will even carve its way through the very center of entire planets to get back to Thor.[26] Mjölnir can also transform Thor into his civilian guises. When Thor is a civilian, the hammer most often becomes an old wooden cane. While employing a mortal guise, Thor would transform back into his mortal form if he was separated from Mjölnir for more than 60 seconds.[28] A variation of this power was revealed when Mjölnir temporarily transformed into Jane Foster's human persona to fool S.H.I.E.L.D. agents into thinking that Jane and Thor were two separate people. However, Mjölnir explained that this power required a great deal of energy and would likely be at least 100 years before it could be done again.[27]
  • Weather Manipulation: Wielding Mjölnir grants Thor the ability to control the base elements of a storm , i.e. rain, wind, thunder, lightning and more (although Thor can control them by himself, it seems that Mjolnir boosts his ability of controlling the base elements of a storm). He can create giant raging electrical storms complete with thunder, lightning, hurricane-force winds, tornadoes, blizzards, tidal waves, exploding volcanoes, earthquakes and torrential rains across entire planets at a moment's notice. He can also create any of these phenomena individually. Another aspect of this power allows him to stop any of these weather conditions instantly as well. Thor can create storms on a planetary wide scale or larger if needed, and is not limited to the normal limits of Mother Nature and can go beyond and defy what natural weather can do such as creating rain in space where there is no atmosphere. Thor's ability to control and create storms extends to any and all storms as he has been shown to control and create raging temporal storms in time, create Solar Flares, powerful stellar winds in space and so on.
  • Flight: Thor is capable of hurling Mjölnir with great force and, by holding onto the leather thong, is capable of flying through the air at tremendous speeds. While in an Earth-like atmosphere, Thor generally flies at roughly the Speed of Sound, roughly 770 miles per hour. Thor can fly so fast that he is invisible to the naked eye.[29] He has been clocked flying at three times the speed of light,[30] and is capable of achieving speeds far greater than that. In fact, Thor can throw Mjolnir at several times the speed of light[31][32], and also swing Mjolnir at several times the speed of light while his strength was reduced in half.[33] It has been established that the speed of Thor's hammer transcends both time and space.[34] Mjolnir can also perform complicated maneuvers in the air,[35] and change course in mid-flight at the speed of thought.[36] By spinning Mjölnir at high speeds over his head, Thor is able to hover in midair, and has even shown the ability to fly without the aid of Mjolnir.
  • Energy Projection: With Mjölnir, Thor can project powerful mystical blasts of energy. He can even channel energies for stronger energy attacks.
God Blast: Thor is capable of channeling different amounts of his godly energies in combination with the mystical properties of Mjölnir can be channeled through his hammer for a single massive blast known as the God Blast.[15][37] His godly energy is so vast and powerful, that even when reinforced with the Belt of Strength, which should double Mjölnir's fortification and durability, when Thor channeled his godly energies into Mjölnir to destroy the Brain Dome of the mighty Celestial Exitar,[15] the hammer shattered from the amount of power Thor channeled. The God Blast is so immensely powerful and destructive that it has proven capable of destroying beings as large and as powerful as the being Galactus, who was forced to flee for his life.[38] Thor can send the God Blast to the core of Ego the Living Planet and Alter Ego and render both comatose.[39] He has also used the God Blast to defeat Surtur, Ymir, Juggernaut, and Zelia.
Anti-Force: Thor is capable of producing an indescribably powerful blast known as the Anti-Force which is capable of annihilating entire planets.[40] This blast is so powerful that with just a single emission, Thor was capable of putting down and seemingly killing the powerful entity Mangog himself.
Thermo-blast: Thor has the ability to produce a universe shaking thermo-blast capable of decimating even entire planets and beings as powerful as Ego the Living Planet.[41]
  • Barriers: With Mjölnir, Thor is capable of creating powerful barriers, force fields and vortexes that are impenetrable. Not even Earth's most advanced weapons could weaken Thor's barrier field that shielded the U.N. headquarters.[42] Thor stated that he could have contained a cosmic flash attack from Stellaris, this blast was strong enough to destroy the planet Earth.[43] These vortexes and barriers are so immensely durable that Thor was able to completely contain the explosion generated by a life bomb, which is so powerful it would have completely destroyed a fifth of the Marvel Universe, without the vortex even faltering, meaning that Thor literally contained a blast that is capable of annihilating millions upon millions of galaxies.[44]
  • Energy Sensing: Mjölnir can detect practically all types of energy.[45][46][47] It reacts particularly strongly to evil psychic energy,[48] and supernatural energy.[49]. Mjölnir can also track down the energy pattern of someone in hiding,[50] detect any Asgardian's aura by their electrons discharge,[51] and can sense and track the energy radiating from mystical objects.[52]
  • Energy Absorption and Redirection: Thor is able to use Mjölnir to absorb any energy blasts directed towards him as means of attack. Once the energy is absorbed, Thor can redirect it back amplified many times over towards the source and/or use it as a weapon of his own. Thor has used Mjölnir to reflect the vast and hazardous amounts of energy being emitted by the biological weapon implanted within the Wasp's body by the Skrulls back at her while all of Earth's other super humans were helpless. Thor used Mjölnir to absorb Ultron's entire energy source, the Silver Surfer's Power Cosmic,[53]Sky-Walker's Cosmic Tempest,[54] radio active energy,[55] magnetism[56] such as Magneto's personal magnetic field[57] and a portion of Pangoria's planetary magnetic field. Mjölnir's ability to absorb energy is so powerful he managed to absorb, contain and redirect the entire energy of the Null Bomb, which was powerful enough to destroy the entire galaxy,[58] absorb mystical energies, such as Pluto's mystic flame.[59] He was even able to absorb a portion of the mystical energies from every god pantheon on Earth,[60] and absorbed the electromagnetic energies of the Celestial Mother-ship.[61]
  • Teleportation: By grasping Mjölnir by the leather thong and rapidly swirling it, Thor can channel energies for the purpose of Wormholes through means of a vortex[62] and in this vortex time has no meaning, which means he and others can pass through it to their destinations instantaneously.[63] He can open gateways which allow him to travel across locations no matter how great the distance within moments or even across entire dimensions, as he does when he travels from Asgard to Earth and vice-versa.[64][65] Thor has used Mjölnir to rip the fabric of the universe to send Surtur and Ymir to the Death Dimension[66] and send an entire population to Limbo,[67] Thor can also use Mjölnir to travel through portals anywhere within the same dimension.[68]
  • Matter Manipulation: By spinning Mjölnir in a precise manner at cyclotronic speeds, Thor can manipulate matter from a molecular level to a vast scale, which allows him to create other configurations and even allows him to transmute the elements themselves. This ability was evident when he transmuted the Absorbing Man's wood and iron body to the gas helium.[49]
  • Resurrection: While channeling his power through Mjölnir, Thor was able to resurrect a man he had wrongly killed.[69]
  • Alpha Particles: Thor's hammer can harness Alpha Particles from the atmosphere and could use it to atomize any weaponry.[70]
  • Negation of Mystic Energy: He used this ability on the Juggernaut himself to negate the mystical energies that grant him his mystical invulnerability, allowing him to defeat Juggernaut in combat. He was able to stop Mephisto from taking human souls to the Dark Dimension.[71]
  • Nether World Power: Thor can use Mjölnir to tap into the power of the Nether Worlds (dark dimensions).[72]
  • Cosmic Energy: Mjölnir allows Thor to produce and control Cosmic Energy to an unknown limit for a variety of purposes. [73]
  • Electromagnetic Spectrum Manipulation: Thor was able to absorb and manipulate the electromagnetic energies of the Celestial Mothership.[61]
  • Invisibility and Intangibility: Thor can turn himself or others, using Mjölnir, completely intangible and/or invisible.[74] An offshoot of this ability is that Thor can use Mjölnir to completely disrupt the phasing abilities of super humans such as the Vision, Shadowcat etc.[75]
  • Event Recall: Thor can use Mjölnir to recall past events.[76]
  • Transmigration of Souls: Thor's hammer has the ability to manipulate souls.[77]
  • Life Force Absorption: Thor used this ability on the super villain the Presence, who was forced to surrender to prevent himself from being reduced to a lifeless husk.[78]
  • Illusion Detection: Mjölnir can distinguish images, holograms, and different illusions from reality: Thor once commanded the hammer to strike the demon lord Mephisto, who was hiding among false images of himself.[71]
  • Interdimensional Messaging: Thor can used Mjölnir to send psychic messages between the nine realms.
  • Holy Object: As a former religious relic, Mjölnir is lethal to vampires. Thor once threw Mjölnir at a vampire, with contact causing the vampire to burst into flame and crumble to dust.[79]
  • Transformation: When Thor was living on Earth under his mortal guise, he could use Mjölnir to transfer from his Donald Blake persona into Thor and vice versa. Thor loses this ability when Odin permanently separates the two personas. The transformation returns after Odin's death and Ragnarök restore Donald Blake to existence, allowing him to draw Thor back to Earth from the void once he finds the hammer, but for a time the two share an existence where they are distinct individuals who nevertheless have a similar memory.
  • Immunity to Other Forces: Even without activating the powers of Mjölnir, Thor's hammer, enchanted by Odin, is impervious to nearly all forms of change, as he himself claimed that no power in the universe but the All-Father's could affect Mjölnir, shown when Amora's magical efforts during her first confrontation with Thor to change it into a deadly serpent availed her naught.
  • Time Travel/Chronokinesis: Mjölnir can bend space and time and allow itself and its holder to travel through time.[80][81] Mjölnir lost this ability when Thor was convinced by Immortus to remove it to help the planet Phantus, which was trapped in Limbo.[82] This was later revealed to be a hoax by Immortus to deprive the Avengers of their main means of time travel.[83] In spite of this, Mjölnir is still capable of manipulating time[74], to the extent that Mister Gryphon attempted to use it as part of his plan to return home[84] only to be defeated by the temporal paradox of two different versions of the hammer striking each other.[85]
  • Allspeak: Thanks to the Allspeak, the wielder of Mjölnir can communicate with and be understood by all races.

Mjolnir the Mighty Hammer of Thor On Earth-199999, Thor has been entrusted with the mighty hammer Mjölnir, which was forged in the heart of a dying star. When Thor was banished to Earth, Odin placed the worthiness enchantment on it and thus the hammer's use became restricted to the worthy, leaving even the Hulk unable to lift it from the ground. The enchantment is represented by the appearance of a Celtic trefoil knot on the side of the hammer's head. At Thor's initial banishment, he himself was unable to wield the hammer or access his powers until he had proven himself worthy of it. The hammer was found by S.H.I.E.L.D.,[18] deemed as an 0-8-4,[86] and studied. Once Thor had proven his worth, Mjölnir itself returned to him of its own accord and his powers were restored, though he required the hammer to achieve his full strength. Although indestructible and with unmatched power, the hammer has proven unable to break Captain America's shield due to its vibranium composition. Thor has taken advantage of the hammer's worthiness enchantment at least once, setting it on top of Loki's chest to pin him to the ground. Thor and the other Avengers later played a 'game' where the rest of the team attempted and failed to lift it from the table where Thor had placed it, with only Steve Rogers able to make it move even if he couldn't pick it up. The worthiness enchantment later helped the Avengers confirm that they could trust the Vision to aid them against Ultron when the Vision managed to lift the hammer where all of them had failed to do so. Thor

Mjolnir (Earth-1610) from Ultimate Power Vol 1 5 0001Ultimate Mjolnir In the Ultimate Universe Thor has multiple hammers which carry the name Mjölnir, and he can wield whichever he deems fit. His original hammer was forged by Odin and carried with it a piece of Asgard so that even if Ragnarök ever took place, Asgard could be reborn. This hammer shares the same powers as the classic version of the hammer, but can also teleport objects and people of a vast quantity and does not have the worthiness restriction, allowing anyone to use it. When Ragnarök inevitably occurred, Thor was reborn on Earth as a human being named Thorlief Goleman and eventually worked for the E.D.I. as a test subject for their Bio-Mech Suit, which came with an axe-hammer hybrid. At Thor's suggestion, the hammer actually housed the battery which powers the suit.[87] Thor became a super-powered humanitarian, using the suit as his source of his powers since he was no longer a god.[88] Through Loki's deceit, Thor was stripped of the harness and hammer, rendering him powerless. Odin was eventually reborn, and thus Thor would regain his godhood. Odin then gave Thor a second version of Mjölnir that resembled the Earth-made axe-hammer.[89]

During a brief battle with with an Alternate Universe, Mjölnir was taken by Hyperion and used against Thor. Hyperion, thinking Thor beaten, simply dropped the hammer as he no longer needed it.[90]

Thor eventually went back to wielding his original Asgardian hammer. After the Ultimates battled Ultron and Magneto, Thor lost his hammer to Magneto, who was able to manipulate it because iron was used in its construction.[91] Magneto then wielded it as a sign of power while he caused a flood which killed many inhabitants of New York. Thor sacrificed himself to Valhalla in order to save the life of Valkyrie. When the remaining heroes defeated and killed Magneto, Valkyrie became the new wielder of Mjölnir.[92] Eventually the Defenders managed to steal it from her and deliver it to their master, Loki. Loki then used Mjölnir to transport his Troll Army from Asgard to New York in a plot to bring Thor back from Valhalla. Thor inevitably returned when Loki murdered Valkyrie, and she took his place in Valhalla. Thor once again wielded Mjölnir and the heroes were able to defeat Loki.[93]

Shortly thereafter, Gregory Stark attempted to cause unrest in Korea. When he was confronted by the Ultimates, he managed to take Mjölnir from Thor and use it to subdue him as well as Captain America, before slamming the ground with it causing a massive shock wave which stunned everyone within range. Thor managed to regain Mjölnir and killed Gregory with a lightning bolt.[94]

When the Children of Tomorrow slaughtered the Asgardians and initiated a second Ragnarök, Thor hid his son Modi, in the Room with No Doors along with Mjölnir, in hopes that his son may one day emerge and restore Asgard to its former glory[95].

With Yggdrasil drained of the Odinforce, Thor has become mortal again. When Tony Stark returned an enhanced version of Thor's former power harness, he once again wielded a similar Axe-Hammer that was given to him by the E.D.I.[96] This newest version of Mjölnir is "fully compatible with all Iron Man power sources".[97] Though the hammer shares all the powers of his magical hammer, Thor still feels like he has become less than what he was.[98]

Thor's son Modi, corrupted by the World Tree returned to earth with the Uru Mjölnir in a quest to establish his kingdom on Earth. When Thor slew his son in combat, the Thunder god continued to use the Stark Model of Mjölnir as well as the linking bio-suit.[99]

After the death[100] and rebirth of Earth-616, an Earth-1610 Mjolnir appeared in the Realm of Asgard and landed in ruined City of Asgard.[101] After learning about the Mjolnir from the Unseen, Thor of Earth-616 went to Asgard in an attempt to retrieve it[102] after becoming unworthy of wielding his reality's Mjolnir.[8] However, Thor was captured by the Collector and brought aboard his ship. The Collector told Thor that he wanted to wield the Mjolnir, but it had killed anyone who attempted to lift it with the exception of the Collector himself, though the Collector was still unable to budge it. This had forced the Collector to take the entire City of Asgard in order to bring the hammer with him.[103] Thor and the Collector weren't the only ones after the hammer, though. The Mad Titan Thanos sent his minions Proxima Midnight and Black Swan to help a unknown cloaked individual retrieve the hammer as a tribute in order to curry Thanos' favor.[104]

A fight eventually ensued between the three sides over the future ownership of the hammer.[105] Thor ended the feud when he activated the hammer's teleportation power to transport himself, the City of Asgard, and his allies away. Feeling unworthy of the hammer, Thor chose to leave the hammer in the City of Asgard so no other villain could abuse its power. Days later,[106] Volstagg appeared and claimed the hammer for himself, proclaiming that the Nine Realms needed a new kind of Thor and he would become that Thor.[107]

Alternate Realities

Mjölnir's Duplicates

Thor's sacred uru hammer has been duplicated with varying degrees of success over the years:

  • Three unnamed duplicates of Mjölnir was created by Professor Zaxton using his duplicating machine[138], all of which eventually faded away into the nothingness from which they came.
  • Crusher - hammer forged from Uru metal for Red Norvell, who once proved worthy to wield Mjölnir.[110]
  • After Thor defeated an unarmed humanoid antibody of Exitar with Mjölnir, more humanoid antibodies swarmed him -- all armed with similar hammers.[141]
  • Thunderstrike - the enchanted mace that was given to Eric Masterson by Thor[142], cause he proved worthy to wield Mjölnir[111] and served Asgard for many years before being returned to Earth.
  • Kevin Masterson, Eric Masterson's son, carried a toy version of Thunderstrike[143] because Thor had so often saved his father's life.
  • Frogjolnir - Simon Walterson lifted a sliver of Mjölnir, which when struck on the ground turned him into Throg and the sliver into Frogjolnir.[145]


  • The exact nature of what makes a person "worthy" of Thor's power has always been in dispute, but at least prior to Jane Foster's acquisition of the hammer, the idea of who could use the hammer was that the person had to be a warrior, someone who could even use lethal force. Thus, while Superman is considered to be a counterpart to Captain America in importance, he had to gain permission from Odin to use the hammer because he wasn't warrior material.
