This is what powers the Horde!

— Mjölnir, The Mighty Thor

Likely inspired by how hammers make noises that could be compared to thunder, fiction frequently grants them the power to generate electricity or command storms. The sight of a hammer charged with electricity also falls under Rule of Cool so there's that. Designs usually range from a giant two-handed or a one-handed war hammer.

The Trope Maker is Mjölnir, the mystical hammer wielded by the Norse god Thor, associated with lightning to Thor's thunder, which means Mjölnir is what's lightning as it flashes through the air from Thor wielding it. Thunder Hammers are often either Mjölnir itself, named after it or is an Expy of the mythical hammer.

Compare Thunder Drum. Sub-Trope of Shock and Awe and Elemental Weapon. Sister Trope to Lightning Gun, Shock Stick, Static Stun Gun and Lightning Lash. Frequently overlaps with Humongous-Headed Hammer.

    Anime & Manga 
  • Digimon:
    • Digimon Adventure: Zudomon has an attack called Hammer Spark, which charges the "Thor Hammer" he wields with electricity. Confusingly, the English dub renamed both the attack and the weapon to "Vulcan's Hammer"note .
    • Digimon Frontier: Invoked by the names of Blitzmon's attacks, "Thor Hammer" and "Mjölnir Thunder". The former has him clasp his hands together and swing them down while they are charged with lightning, while the latter is a Ground Punch which releases an electric blast. None of these attacks actually involve an electrified hammer but their names reference the mythical hammer of the Norse Thunder God.
    • Digimon Adventure: (2020): Not only do Zudomon and his Hammer Spark return, he also has a ranged version of the attack where he fires an electrified beam from the hammer.
  • Fate/kaleid liner PRISMA☆ILLYA: Mjolnir is wielded by Beatrice Flowerchild since she possesses the Berserker class card connected to Thor. The hammer is roughly three times her size and requires her to enlarge her entire arm just to hold it. Mjolnir turns out to be a massive Red Herring for this Berserker's True Name - rather than being derived from Thor, the card is instead derived from Magni, one of Thor's sons who inherited the hammer after his father's death during Ragnarok.
  • Mobile Fighter G Gundam: The Zeus Gundam's Lightning Hammer is a large yellow hammer with a bolt-shaped handle. It is based on Thor's Mjölnir and can be charged with electricity to shock the enemy. The lightning abilities do not seem to be restricted to the Lightning Hammer as when another Zeus Gundam appeared in Gundam Build Fighters, it was able to channel the same abilities using a random stock hammer.
  • Record of Ragnarok: Mjölnir is a massive hammer larger than Thor's entire body. Thor can channel electricity through the hammer, making his swings even more powerful and devastating.
  • Soul Eater: Marie Mjolnir's weapon form is either a hammer or a tonfa. True to her namesake, she's able to utilize her soul wavelength to generate electricity.

    Comic Books 
  • De Rode Ridder: The hammer is of course the focal point in the album De Hamer van Thor note . Both Mjollnir and Gungnir also make an appearance in the album De Walkure note , where they are wielded by their original owners. The album Doodsbrenger note  briefly shows how Mjollnir was originally forged (from mithril, according to the story!), but instead focusses on the sword Deathbringer, which was forged at the same time but ended up hidden on Midgard, where it was eventually found by the album's main villain.
  • Steel's hammer has a variety of features revolving around electromagnetism. It can measure electromagnetic energy, generate EMPs to disrupt machinery and be tuned to the Earth's magnetic field, making it impossible to move. When not in use, the hammer can be magnetically attached to Steel's back.
  • The Mighty Thor:
    • As expected in a comic based on Norse myth, the titular character wields the Trope Maker. Thor (2014) reveals that the piece of Uru Mjölnir was created from contained a cosmic storm called the God Tempest.
    • Beta Ray Bill has Stormbreaker, a hammer/axe, with similar powers to Mjölnir. It was created for Bill when it was found out that he was worthy enough to carry Mjölnir since he and Thor can't exactly use the same weapon.
    • The Ultimate Marvel version of Thor has multiple hammers named Mjölnir. His original hammer has the same powers as the 616 version.
  • Valhalla: Thor wields the Trope Maker Mjölnir, here presented as a short-hafted one-handed hammer that neatly fits in his hand. Thor can cause thunder and lighting to erupt from the hammer by brandishing it.
  • X-Men: In the 80s, when Storm was going through her depowered "Mohawk phase", a 1985 story in X-Men Annual saw Loki attempt to manipulate her into allying with him by giving her a knock-off Mjolnir called Stormcaster, which gave her back her Weather Control powers so long as she wields it. She was forced to surrender the hammer when she thwarted Loki's plan.

    Film — Live Action 

  • Fengshen Yanyi: One of Tongtian Jiaozhu's many deadly Paopei are the Purple Lightning Hammers, which are apparently extremely powerful weapons that can break through even other lesser Paopei.
  • Magnus Chase and the Gods of Asgard: As usual, Mjölnir is Thor's weapon. Although it spends almost two books missing.

    Live-Action TV 
  • First Wave: Mjolnir shows up as an alien device that can create portals.
  • Gods of Honour: The series revolves around the birth and origins of gods, with Leigong as one of the three main characters (alongside Nezha the Warrior and Erlang the Guardian). True to the myth, Leigong does get his enchanted mallet and spike halfway in the show, allowing him to battle demons by striking them down with thunderbolts.
  • Power Rangers Operation Overdrive: Thor appears in the episode "Hammer Time" and as expected wields Mjölnir, an oddly Japanese-looking version of it to be precise. This is mostly because it is a case of Cultural Translation due to it coming from a Boukenger storyline involving the Conjuring Mallet. In addition to its Sizeshifter powers from the stock footage, Thor is shown using it to create blasts of lightning.
  • Supernatural: Mjölnir is auctioned off in the episode "What's Up Tiger Mommy?" by Plutus, the Greek God of Greed. When Sam manages to get his hands on it, he is able to strike down gods.

    Myths & Religion 
  • Chinese Mythology: Leigong ("Lord of Thunder") is the Chinese equivalent of Thor. He is depicted as a bird-headed humanoid who carries a mallet and drum which can produce thunder, and a chisel to punish evildoers. He is often depicted as being accompanied by Dianmu ("Mother of Lightning") and Yuntong (Child of Clouds) who assist him in creating thunderstorms.
  • Norse Mythology: Mjölnir is the Trope Maker and Trope Codifier. It is both a powerful weapon and an instrument that can provide blessings.
  • Celtic Mythology has Lorg Mor (Lore-ug More), "Great Staff" the signature weapon of The Dagda, the Top God of the Irish pantheon. It is usually described as a staff or club (the word "lorg" can mean either in Irish Gaelic). Unlike most examples of this trope, one end not only channels Dagda's powers (which includes weather control) bringing death and destruction, but the other end actually revives the slain. He notably used its storm abilities when battling the sea monster muirselche.

    Tabletop Games 
  • Dungeons & Dragons:
    • In the supplement Deities & Demigods Cyclopedia: Thor's magical hammer Mjölnir can fire a total of 100d6 worth of lightning bolts per day, divided up as the god wishes.
    • The Hammer of Thunderbolts is, depending on the edition, either a really powerful magic hammer or an outright artifact. Heavily based on Mjölnir, if wielded by someone who's also wearing Gauntlets of Ogre Power and a Belt of Giant Strength, it gives the wielder god-like strength and the ability to hurl the Hammer at distant foes to release mighty thunderclaps that damage and stun all nearby creatures. If the target is a giant, they must also make a saving throw or be instantly struck dead by the impact.
  • Fabula Ultima: One of the sample rare heavy weapons is Mjolnir, a one-handed hammer that inflicts both bolt damage and the Dazed status effect to anyone it hits.
  • Pathfinder: The minor artifact Hammer of Thunderbolts is essentially a lesser version of Mjölnir (and is also featured in Dungeons & Dragons). It requires other magic items (based on Thor's belt and gloves) to be worn to be used at full power.
  • Warhammer 40,000: The Thunder Hammers are huge war hammers used by Space Marine Terminators. They have disruption fields designed to activate on impact, greatly increasing the damage they deal and producing a crack of thunder. For Astartes Terminators they are usually one-handed and reasonably sized, however they can also come in two-handed Humongous-Headed Hammer style for space marines wearing regular power armor.

  • Dicey Dungeons:
    • The card Hammer, which does raw damagenote  and shocks one of the enemy's cards if you put in a 6 (or any even number if upgraded). If Inventor's art is anything to go by, this is a completely regular claw hammer.

  • God of War (PS4): The smiths who forged Mjolnir, Brok and Sindri, are supporting characters who aid Kratos and Atreus by providing crafting services. They are deeply ashamed of forging Mjolnir since Thor used it to slay countless Giants. Thor's sons Magni and Modi are in fierce competition with each other over the right to inherit the hammer. The hammer itself makes an appearance in The Stinger when Thor appears in front of Kratos's house in Atreus's dream.
  • God of War Ragnarök: Continuing on from the previous game, Thor shows up with Mjolnir in tow and is shown to be capable of tossing and recalling it like Kratos with his axe. When the two collide, it creates a massive frozen lightning bolt that stretches to the skies.

While not electrified by default, under the influence of the Tome of Power it not only gains the ability to fly through the air at a toss, but then on impact also strikes those that it hits with bolts of lightning.

    • In Persona 5, Mjölnir is one of the strongest weapons available to Ryuji Sakamoto, and can only be obtained by itemizing Thor. Appropriately, Ryuji specializes in Electricity himself, and Mjölnir improves his Electricity output on par with the passive skill Elec Boost. Oddly, it's actually a mace.

  • Titan Quest: The "Essence of Donar's Hammer" relic sounds like it should be this as Donar is another name for Thor. However, it does not have much of a electricity connection beyond inflicting "Stun" or generic elemental damage.
    Donar, or Thor, is the Germanic god of thunder. A son of giants himself, he uses his mighty hammer to protect the world from all kinds of monsters.
  • Transformers: Devastation: There is a large assortment of giant hammers in the game and all the non-unique weapons have Fire, Ice, Lightning variants. Naturally, there are lightning hammers that deal shock damage, which Optimus and Grimlock can use. Humorously enough the regular giant hammers' design harken back to the Magnus Hammer from Transformers: Animated, so them getting electrified can count as a Mythology Gag.

    • The Mountain King Hero Unit in Warcraft III wields a hammer which he uses to perform his Storm Bolt and Thunder Clap attacks. Muradin retains these abilities in Heroes of the Storm.
