It comes from nowhere, it strikes without mercy, and disappears again. It's a mallet the size of a circus sledgehammer, and it's evidence that Anime characters watch too many Bugs Bunny cartoons or Three Stooges shorts. An angry character - usually but not restricted to short-tempered schoolgirls - can often whip out a massive hammer with which to slam the target (and cause) of her ire.

In Fanfic circles, the notional storage place for mallets when not in use is known as "Hammerspace" or "malletspace".

A recent variation is to have the character pull out a harisen, a huge folded fan made out of paper or metal, a.k.a. the Paper Fan of Doom, and smack them with that. This is usually less painful-looking than the mallet, unless she uses it to deliver a Megaton Punch.

Ironically, this is now a Dead Horse Trope in the West, where it originated; modern Western examples are typically from shows invoking anime, which has added its own touches to the mix, or from homages to Warner Brothers cartoons.

For more tropes on the spontaneous generation of matter, see Shapeshifter Baggage, Elemental Baggage, Variable-Length Chain and Telescoping Robot.

For characters that use hammers for purposes other than comedy, see Drop the Hammer, for when the Trope is enacted for comic effect but the actual reason the girl is supposed to be angry is missing from the context see Unprovoked Pervert Payback.

When the character (often but not always a video game character) carries more than one weapon this way, that's a Hyperspace Arsenal.

Examples of Hyperspace Mallet include:


  • On a commercial for the Cartoon Network, a man being stalked by a mugger calls Cartoon 911 and is advised to reach behind his back and pull out a giant hammer.

Anime and Manga

  • Kaori in City Hunter; She pulls an over 100t iron hammer out of nowhere to beat Ryo up. In the alternate timeline of Angel Heart, Shanin picks up this ability from Kaori's heart inside her. We later find that Kaori's sister can also do it.
    • In one of the anime episodes, Kaori is shown to have purchased a new hammer at a boutique before the action of the episode started.
  • Ranma ½ uses it on occasion. Fanon makes it far more prominent and always has Akane Tendo to be the one to use it; this actually varies depending on continuity. In the anime, Akane only uses a hammer four times: the third and fifth season episodes "Ryoga's Miracle Cure!" and "Into the Darkness" respectively, the OAV "Team Ranma Vs. The Legendary Phoenix", and the first movie "Big Trouble in Nekonron, China". (And a first-season episode shows the hammer is a hand-me-down, given to Akane by Kasumi of all people.) It's only slightly more prominent in the manga, and just about everyone has used it, from Kodachi (the first person to wield it) to Soun Tendo to Happosai to Ranma Saotome himself.
    • In the manga Akane most frequently uses her fists, samurai weaponry such as shinai and bokken, or usually any blunt object at hand. She doesn't really use a mallet more than anyone else.
    • In the manga, Ranma actually uses one, too — on Ryoga, when this one is trying to get rid of a powerful, yet shameful painting on his tummy.
    • So pervasive and insidious is the view that Akane is a "hammer girl" (the "Weapon of Choice" kind, not the "No Natural Buoyancy" kind - although the latter actually is canon) that many of the Ranma ½ video games actually give her a huge wooden mallet as a legitimate attack.
    • In its first appearance in the abridged series, Kodachi calls out "Hyperspace mallet!" as she attacks with it.
  • Shinobu and others in Urusei Yatsura.
  • Kodomo no Omocha parodies the mallet cliche by having its characters use squeaky plastic mallets with collapsible heads.
    • Parodies it mercilessly on many occasions, from Hayama asking Sana to take out her hammer (and then stealing it and hitting her with it) to Hayama showing off his martial arts skills by dodging it (prompting Sana to pull out another one and smack him with it with an obligatory "Too slow!").
  • The Beach Episode of Mai-Otome shows Mashiro whipping out a squeaky mallet with which to assault Nagi.
  • Amy Rose in Sonic X (and the Sonic the Hedgehog games where she's playable, for that matter) has the ability to pull her Piko Piko Hammer out of nowhere, even multiple hammers if one gets destroyed.
    • And her ship in the third season.
    • Made better by the fact that you see it materialize as if Transported in on occasion.
    • Amy is a rare character who actually fully utilises her hammer against her enemies rather than just punishing friends.
  • Sunako in The Wallflower has the ability to materialise a Grim Reaper's scythe in times of... fragile sanity. It isn't metaphorical, either; she occasionally uses it as a tool, and other characters react somewhat understandably when the already scary Sunako is suddenly holding a scythe that's taller than she is.
    • This is apparently a genetic trait, as Sunako's father also materialises a wooden sword in a lightning bolt when he is angry.
  • Carerra Marker from Karin manifests her deadly slipper from hyperspace, complete with Battle Aura.
    • A better example is when Winner pulls out a spear taller than himself while proclaiming his intent to protect Karin. Lampshaded when she replies "....Where did you get that from?"
  • A variation in Love Hina, Episode 18; Sarah MacDougal, who has a history of throwing and/or breaking pottery, does so this time by seemingly pulling them out of nowhere.
  • Vita, from the Magical Girl Lyrical Nanoha series, wields one of the few non-comedic Hyperspace Mallets. Distinguished from Drop the Hammer because it really does appear from hyperspace.
  • One Piece, in Usopp's fight against Mr. 4 he uses a gigantic hammer. But it turns out that the hammer is actually fake and can collapse for storage.
    • In a straighter example of the trope, one of Whitebeard's commanders can pull a giant hammer out of a small compartment in his chin.
  • Misty used such a mallet in a few occasions in Pokémon, especially on Brock. She seems to be particularly talented, as she once even produced a gong to wake Ash and Pikachu up.
    • In the Pokémon Special manga, the Gold/Silver/Crystal arc main character Gold can conjure a billiards stick out of seemingly nowhere, despite the fact that it looks about as tall as he is.
      • It's shown to be retractable. Yellow's fishing rod, on the other hand...
    • Jessie has also pulled mallets out of hyperspace, as well as frying pans.
    • The unnamed TV reporter from Pokémon Diamond and Pearl Adventures pulled one out when she was aggravated with Hareta; however, the entire gag was that he was popping out of holes in the ground like a game of Whack-A-Mole.

Cameraman: W-what are you carrying that around for?

  • Kaname from Full Metal Panic! often uses a hyperspace Paper Fan of Doom to punish Sousuke. (Actually, she can sometimes be seen in Fumoffu carrying said Paper Fan of Doom in her school portfolio.)
  • Katekyo Hitman Reborn apparently uses this several times:
    • Reborn's shape-shifting chameleon turns into a mallet which he hits people with (most notably Tsuna and Lambo) when they don't answer his questions correctly, or when he's technically annoyed with them.
    • He's also done that to the Arcobaleno Skull, too, when in the filler arc, Skull screwed up his Trial, and Reborn ticked off about that Don't forget that Colonello added his fists into this, and the Skull asks for Lal's mercy, and she just simply gives the cold shoulder.
  • In one episode of Princess Resurrection, the main characters are fleeing from their enemies on a jet ski. During one cut back to the heroes, Hime is suddenly wielding a giant metal hammer.
  • Eve from Black Cat averts this trope, as she just needs to change her hand into a mallet.
  • Variant: Maka from Soul Eater has a heavy book that follows all the conventions of this trope, barring its shape.
    • Also Shinigami and his gigantic hands. Students or staff pissing you off? Smack them on the head. Also good for punishing Big Bads and evil witches.
    • Tsubaki also attacked Black*Star with shurikens to the forehead in early chapters/episodes.
  • Guchuko, the feral mochi-mochi in Potemayo, has a portal into hammerspace inside her pants. She keeps her axe in there, for one thing, but at other times she variously keeps a snake and a pile of corn cobs. That may have been how she transported the carcass of a cow into Kyo's yard. (Quite a feat considering that Guchuko is about the size of a cat.)
  • Bludgeoning Angel Dokuro-chan. In spades. The whole focal point of the anime is the title character producing a giant spiky club from nowhere and brutally killing the protagonist, only to revive him seconds later. She also appears to take a hologram-phone device from her panties at some points.
  • Hayate the Combat Butler characters seem to love this one, most often with Sakuya pulling out her paper fan to smack people. Nagi pulls out a spiked hammer when Hayate annoys her.
    • Although not a hammer, Hinagiku pulls her borrowed wooden sword out of nowhere. Sometimes this even surprises her. This was explained and is a plot point, while the Sakuya and Nagi examples are played for laughs.
  • King Dedede in the Kirby: Right Back at Ya! often hits Kirby or Escargon with a Mallet. Kirby even gets hit in the opening!

Comic Books

  • In Spider-Man on occasion Carnage will form a mallet from his body and smash his enemies with it.
    • Sandman does it with his hands on occasion. Sometimes he even creates spiked mallets.
  • The titular character of Leonard Le Genie often pulls hammers, anvils and other heavy, blunt objects from his beard to punish his clumsy assistant Basile.
  • A modern western example / subversion / Shout-Out can be found in the Scott Pilgrim books where Ramona Flowers will often pull large weapons out of her subspace handbag. Including a hammer (+2 against girls!).
  • This is Slapstick's primary method of attack.
  • In one strip of the Italian Comic Lupo Alberto, one of the two characters starts talking about old comics and their "special effects", until the other one, annoyed, reminds him the last one, A.K.A. said "Mallet that popped out of nowhere used to punish the bad guys".


  • In the 1992 Marx Brothers homage Brain Donors, Harpo's counterpart Jacques pulls a huge wooden sledgehammer out of nowhere when the decision is made to "take care of" egotistical ballet star Volare. He is, unfortunately, restrained from actually using it.
  • In one scene in The Mask, the title character pulls an enormous mallet out of his pocket in order to smash an alarm clock.
  • Highlander and, particularly its spinoffs, makes little to no effort to explain where the immortals pull their swords from. While early on, they'd have characters wearing long coats, later on they'll have characters (particularly females) pull out swords while wearing form fitting clothing.
  • While being less a Mallet and more a Megaton Hammer, Ramona Flowers uses one in Scott Pilgrim vs. the World to fight her ex-girlfriend.
    • As mentioned in the Comics section above, Ramona pulls this full-length sledgehammer out of a handbag that looks small enough to have difficulty containing Scott's self-respect.


  • In the Tom Holt novel Grailblazers, one of the knights has an hereditary power—that any male of his line can, when reaching vaguely behind them, always grab a weapon of some sort.
  • In The Stormlight Archive by Brandon Sanderson, some of the most powerful weapons in the setting, Shardblades, can be summoned from thin air with an effort of will by their owner, they will appear after ten of the owner's heartbeats.

Live Action TV

Newspaper Comics

  • In Pearls Before Swine, Rat once had a "Mallet o' Understanding" which he'd whip out to use on other characters who displeased him.

Tabletop Games

  • In the GURPS anime universe, one of the character abilities is the non-damage-dealing ten-ton hammer that can be pulled out of nowhere. It is only available for female characters.
  • Maid RPG, the game with its roots deep in anime, has "Weapon From Nowhere" as one of Maid Powers. It allows a surprise attack (the target is denied an opposed roll).
  • In Teenagers from Outer Space, the "Hyperspace Hammer" is a standard piece of equipment available to player characters basically at any store. Unlike most of the other examples on this page, it's completely technological — the hammer is literally in hyperspace until needed, and materializes around a beacon device in the character's hand just long enough to hit its target before returning.

Video Games

  • Overlaps with Hyperspace Arsenal, but a vast number of video games incorporate the ability for characters to draw a weapon (or similar tool) at will from nowhere.
  • Amy Rose's signature weapon is a mallet that shows up out of nowhere. There's not a single TV show or video game she shows up in either in which she doesn't have the hammer at all (since Sonic Adventure) or in which she keeps the hammer in a logical place. It gets Lampshaded in Sonic X:

[Amy throws hammer at Eggman's airship]
Eggman: We got your hammer up here, so you can't touch us!
[Amy pulls out another hammer out of nowhere.]
Decoe/Bocoe: Ah!! Another one!
Bokun: She's got more hammers than a hardware store!

  • Literally in the game Patapon 2. Ormen Karmen, the Karmen chief and the Penultimate Boss, has one attack where a gigantic hammer appears in his hands and he crashes it down on the patapons. When he finishes attacking, the hammer shrinks back into the void.
  • In the Super Smash Bros. series, one of Peach's attacks strikes the target with a random blunt object from out of nowhere, such as a golf club.
  • While most of Link's equipment would fall under the Hyperspace Arsenal trope, he does acquire oversized-hammer weapons in various games, such as the Megaton Hammer or the Skull Hammer.
  • A serious example happens in the Elder Scrolls games, where the Bound Weapon / Armor spells are basically pulling an Infinity+1 Weapon or Armor from Hammerspace.
  • Lucca from Chrono Trigger attacks with a hammer if her target is too close for her guns. The hammer always has the same properties as the gun she's equipped with, too.
    • Actually, it is her gun.
      • Not so sure, in her official artworks, she is depicted as carrying a mallet. Its no surprise at all that she carries one since she is a Wrench Wench and hence, the mallet is unlikely to be a hammerspace one.
  • In Lego Batman, Harley Quinn can pull a mallet out of nowhere and bludgeon the enemy with it. This is one of the most effective melee attacks in the game.
  • In Samurai Shodown V, Rimururu has a finishing move that involves freezing her opponent before smashing them with a gigantic ice mallet (which she of course summons out of nowhere.)
  • Mario and Luigi use hammers fairly often. There has never been a logical place that they could be kept. Mario has even reached into the air, have a solid iron hammer the size of a garden shed appear in a puff of smoke (really), which then proceeds to disappear.
  • Peacock from Skullgirls can pull a hammer out of nowhere to whack an enemy with. The creepy part about this is that when she's done with the hammer, where does she put it? She shoves it into one of her empty eye sockets.
