Spontaneous Weapon Creation


"None of your skills will be of any use against a Servant. In that case, at least imagine it. If it is an opponent you cannot match in real life, defeat it with your imagination. If you cannot defeat it yourself, imagine something that you can defeat it with."
Archer, to Shirou Emiya, Fate/stay night

The idea behind this trope is a character with the power to create a weapon. This can either be the power being to create or otherwise summon a weapon, or creating the weapon is but one application of a power they already possess. One character could conjure a weapon out of thin air, while the other created his weapon by clever application of his fire control. Sometimes the character can turn this power Up to Eleven to create a Storm of Blades.

One common use of this trope, especially among the second type, is frequently seen in Tournament Arcs where weapons would otherwise be banned. The person who crafts the weapon will be able to use Loophole Abuse to claim that, since what they're doing is simply an extension of the power they came in with, it's allowed. It usually is.

People who do this will generally possess Elemental Powers. Compare Natural Weapon, which can also fall into the Tournament Arc Loophole Abuse noted above. Contrast Flaming Sword, which is usually an otherwise metal sword that's on fire, rather than a sword made out of fire. Can often come about by characters who possess Imagination Based Superpowers. Shapeshifter Weapon is the one formed from the wielder's body.

Compare Instant Armor and its subtropes for when this sort of thing gets used for defense instead of offense. See also Elemental Punch, when weapons are not in use. A form of Shaping Your Attacks and may or may not involve a Person of Holding. See Summon to Hand for calling existing objects as opposed to creating them — weapons are the most popular application.

    Anime & Manga 
  • A few times in One Piece, with Logia users Aokiji and Kizaru Shaping Their Attacks.
    • Aokiji is An Ice Person, and by taking a few blades of grass and breathing onto them, he freezes himself up an Ice Saber.
    • Kizaru manipulates light, essentially enabling him to wield a Laser Blade.
    • Baby 5 has the Arms-Arms Fruit, a Devil Fruit that allows her to turn herself into various weapons.
    • Even Ceasar Clown gets in on the action, using his Gas-Gas Fruit powers to create a burning blue blade that's essentially an oxygen-torch!
  • Hiei in YuYu Hakusho Plays with Fire, and at one point uses this ability to create a sword made out of Dark Fire. He's reluctant to use this more than he can help though, since it reminds him too much of Kuwabara's Spirit Sword, which is, or more accurately became, an example of this trope as well (it started as him drawing the true power out of a piece of a blessed wooden sword, which became his Spirit Sword's handle; as he got stronger he eventually could just pull the sword out of midair, without the chunk of wood). Kuwabara shows the most flexibility with this power, his Spirit Sword can stretch lengthwise to increase its reach or expand sideways to flatten people (called the Spirit Flyswatter). Bui could make axes and Karasu could make bombs. Touya can makes swords out of ice.
  • When dueling Touma in A Certain Scientific Railgun, Mikoto Misaka uses electromagnetism on the sand and dirt around her to create a Whip Sword out of iron sand.
    • Harumi Kiyama briefly draws an energy blade while fighting Mikoto.
  • Spike the Devil Man from Dragon Ball used his magic to create a pitchfork.
    • Later on in Dragon Ball Z, Dabura used magic to create a sword and a spear.
  • Alchemists from Fullmetal Alchemist can transmute weapons using the mass of floors or walls, although not many alchemists ever actually do so.
  • The "sword of one's heart" from Revolutionary Girl Utena might qualify. It's a regular old steel sword, but you draw it out of your own chest (or your Love Interest and/or creepy stalker figure does it for you).
  • Many characters in Beet the Vandel Buster can conjure weapons called Saiga. Beet is unique in that he can create five, which were given to him by the heroes he admired.
  • Bleach
    • Quincies are capable of producing weapons out of reishi, the spiritual equivalent of "atomic particles". They usually need a physical object as a focus for creating the weapon and the weapon itself tends to be an Energy Weapon, traditionally an Energy Bow, made of Hard Light. However, they can generate these weapons whenever they feel like doing so. Advanced Quincies can make their weapons such a condensed form of energy that the weapon looks solid and physical.
    • When in his resurreccion and segunda etapa forms, Ulquiorra is capable of producing a lance made of energy whenever he likes.
    • Fullbringers are similar to Quincies in that they use a physical object as a focus to producing weapons. However, Fullbringers tend to be more limited in the range of weapons they can produce, usually producing the same weapon every time. Their weapons become physical rather than energy.
  • While she may appear to be an example of conjuration, Erza from Fairy Tail is, in fact, weapon summoning. She has everything stored in a separate location and brings it up to her in battle. The straighter example is Gray and his Ice Make magic.
  • The Pandora from Freezing does this with their Volt Weapon.
  • In Puella Magi Madoka Magica most Puella Magi possess the ability - each summons a specific kind of weapon, though they can apparently be created in any size or quantity. Mami instead has the power to summon ribbons, but is so skilled with them that she can create "ribbon constructs" in the shape of fully functional musket-rifles and cannons. Homura is another exception, having a Bag of Holding she must stock manually, but she switches to summoning a bow in the epilogue.
  • Cures Rouge, Lemonade, Mint and Aqua of Yes Pretty Cure 5 Go Go create weapons out of their elements - a ball of fire, energy whips, energy disks/barrier and water bow and arrows.
  • In Smile Pretty Cure!, Cure Beauty can make an ice sword, which she used to fight Joker.
  • Galvatron does this, supposedly through pure Energon power, in Transformers Cybertron.
  • The Sacred Black Smith: Luke can create metal swords on the spot but the process is a little more involved then snapping his fingers. That's why he needs Cecil to protect him in the meantime.
  • The titular character from Toriko can do this, creating knives and forks of varying sizes composed of Appetite Energy which he uses as projectiles, the latter is also used as a shield.
    • Chin Chinchin also creates a spoon, also of varying sizes and composed of Appetite Energy, to scoop things up, use as wings and shields and even make a dome to seal himself and his enemies inside.
    • Coco can use his his poison to create weapons, such as a sword, a bow and arrow, a spear and even a suit of armor, by combining said poison with the clotting agents from his blood.
  • This is a fairly common trait for super robots, ranging from growing a drill on your forearm to fully functional melee weapons such as axes or swords. Then again, this is just another way they like to screw over the laws of physics.
  • In Naruto the Sound Ninja Kimimaro and Kidomaru can do this by creating weapons out of bone and hardened spider's silk respectively.
  • InuYasha: Sesshoumaru spends a lot of the manga searching for a sword that is suitable for channelling his vast power. He causes a lot of trouble by thinking the only weapon strong enough is his brother's sword Tessaiga. Eventually, it's revealed that Sesshoumaru has possessed all along the power to spontaneously create a sword out of his very soul as the physical manifestation of his true power. However, very specific conditions have to be met before Sesshoumaru can unlock this power and it's only a one-off ability that creates a permanent, physical sword.
  • In Final Fantasy VII: Advent Children, Sephiroth forms the Masamune out of tainted Lifestream just in time to block Cloud's attack.
  • In Claymore, Priscilla consumed her Thunderbolt Iron claymore after she Awakened. She is able to recreate the sword at will whenever she feels up for a swordfight.
  • Nen users in Hunter Hunter can do this depending on their ability. This is primarily the realm of Conjurer-types like Kurapika (who creates chains), but Transmitters and Emitters fashion weapons out of their aura if so desired, such as the 'scissor' form of Gon's Jajanken or Pokkle's rainbow themed arrows.
  • The characters in Seiken Tsukai No World Break are able to utilize this, summoning weapons they used in the past when they were heroes of a different time era.
  • Senki Zesshou Symphogear: One of the standard powers of the Symphogear system is to summon a Morph Weapon known as an Armed Gear.
    • Tsubasa specializes in this among Gear users and can even manifest swords from a distance, up to BFS and Storm of Blades levels.
    • Hibiki, uniquely, cannot summon Gungnir's Armed Gear. She initially has an inferiority complex over this, believing that she's too weak/dumb to use it properly, but eventually she comes to view this as a blessing in disguise. Her true Armed Gear, as she puts it, is her own hands - because she doesn't hold a weapon she's free to hold hands with others.
  • In Endride, certain people in the world of Endora have the ability to call forth Warp Relics. Nobody knows what dictates who gets them, but they are weapons of all descriptions that may level up with use, and are generally considered a prestige item. However, their usefulness can vary and ultimately depends on the wielder.

    Comic Books 
  • As noted in the description, the rings of the Green Lantern can create anything the wearer can imagine. Weapons are just but one of many things they can do.
  • Psylocke's "focused totality of her psychic power" in X-Men is a psychic blade that's able to fry the brain of any foe. At maximum intensity she can kill but it's seldom used this way. After a Re-Power that made her powers telekinetic instead of telepathic, it could function as an Absurdly Sharp Blade that could slice through anything (yet still have its stunning effect if it hit flesh and blood.)
  • This is one of the many possible uses of Invisible Woman's force fields. In one X-Men/Fantastic Four miniseries, she had a Mama Bear moment and used a force sword to slay a Brood queen in close combat, leaving the males of both teams rather shocked.
  • This was the super-power of the minor DC hero Gunfire, who could turn any object into a blaster or bomb weapon with his touch by channeling energy into or through it.
    • Hitman #1,000,000, the Hitman issue tying into and sending up the DC One Million crossover, mercilessly spoofed Gunfire and, by extension, this power, with a particularly inept future counterpart of the original version.
      Gunfire One Million: Pain — so bad! If I can just reach — Medipak — *BLAM* Aaaaahh!! Aaaah, no, I turned the Medipak into a gun!
      Gwant: That really is kinda lame....
      Hitman: Imagine his personal life.
      Gunfire One Million: Oh God, I turned my ass into a hand-grenade — *FOOOMM*
  • The Punisher had this power briefly for two miniseries (Purgatory and Revelation), pulling any kind of angelic weapon from his overcoat.
  • This is the primary ability of the Thor villain Gorr the God Butcher. He wields an ancient weapon known as All-Black the Necrosword, which is capable of creating all sorts of weaponry and armor.
  • Jules from Bazooka Jules has this ability due to a micro-robtic weapon fusing with her body. The weapon placed small dimensional gateways around her body that lead to a dimension filled with nanomachines. When she needs a weapon like a gun, one of the gateways open up, the nanomachines flood out and they manipulated to form that weapon.
  • Quentin Quire takes a page out of Psylocke's book in Wolverine and the X-Men, using his powers to form a psychic shotgun.
  • As of her solo series, Jean Grey manages to do this, if entirely by accident, while fighting orcs alongside the Odinson. It is, predictably considering her company, a 'big frigging magic hammer'. After being unsure how to repeat the trick, she goes to Psylocke for lessons.

    Fan Works 
  • In Ghosts of the Past, sequel of Child of the Storm, Harry Dresden displays his canonical ability to create an energy whip made of soulfire - though a little earlier than canon thanks to tutelage by Wanda.
  • In Past Sins, Nightmare Nyx and Princess Celestia can generate blades out of magic. Princess Luna can do this too (two no less), and so can Twilight Sparkle (in the form of a dagger).
  • In The Hill of Swords, naturally this is Shirou's shtick with his tracing, though Guiche gets in on it, too. Shirou eventually performs the logical conclusion of this trope by pulling out Unlimited Blade Works.
  • In the Pony POV Series:
    • There seem to be a number of spells capable of doing this in various ways, most basic being 'make a weapon appear'. However, like many spells, being able to do this seems to depend on the Cutie Mark.
    • In the Dark World Arc, Fluttercruel has this power as her Personality Power with the Element of Cruelty. She's capable of generating nearly any weapon she wants from her body, such as her hair, feathers, and bones. Rarity gains this power after stealing the Physical Element with her Element of Desire, though due to the spiritual aspect of it, Fluttercruel retains it after performing a Body Surf.
    • According to Loose Canon, Fluttercruel's Redeeming Replacement as bearer of the Element of Cruelty Diamond Tiara has a different Element of Chaos power (namely turn the emotional pain of her words into physical pain), she still possesses the ability to generate weapons out of nowhere due to having cartoon powers.

  • In Spaceballs, it's possible that this is how schwartz weapons like schwartz swords work. Yogurt claims that the rings from which the schwartz weapons appear to come are really a Magic Feather.
  • In Thor the Frost Giants can form weapons out of the ice covering their body.
  • Hela in Thor: Ragnarok can spontaneously manifest blades, which is the result of her being made into a Composite Character with the villain Gorr.

  • In The Dresden Files, Harry Dresden displays the ability to create a whip from soulfire in book 11, Turn Coat. Later, after becoming the Winter Knight, he develops the ability to create claws out of ice.
  • In The Zombie Knight, Hector does this frequently. Presumably, any character with materialization of a material with a crystalline form could do the same, but he is the only one who uses the technique regularly.
  • In The Wheel of Time, Rand occasionally creates a sword made of fire, though this is a rather inefficient use of the One Power, something that Lanfear complains about. The Amyrlin Seat demonstrates the ability to create a sword out of air, then explains that a strong man wielding a steel sword would be more useful.
  • In High School DD Kiba's Sacred Gear "Sword Birth" lets him create magic swords with different elemental attributes in order to counter his opponents' powers.
  • Several characters in Worm have this ability. Examples include:
    • Miss Militia can conjure weapons as her sole power. These weapons can be anything from knives to bazookas, dual-wielded assault rifles, and in one case what seemed to be a nuclear bomb.
    • Circus stores a sledgehammer in an extradimensional space, allowing for what appears to be this trope.
    • One of the Butcher's powers is limited terrakinesis, which is used to create arrows for her bow and a spike which she killed herself on.
    • Glaistig Uaine has a number of powers; at one point, she uses a material-creation power, a telekinetic power, and a Tinker power to create weapons out of thin air.
  • One of Grumph's spells in Spells, Swords, & Stealth is the ability to conjure a magical weapon whose shape he can morph to suit his needs. Using the spell takes a lot out mana, so unless he needs that trait he's just as liable to his slightly more mundane shortsword made of demon bone.
  • The Unexplored Summon://Blood-Sign:
    • Summoners can create their Blood Signs, the tools they use to summon. This usually takes the form of the Blood Sign rapidly assembling itself from its components (e.g. coins stacking on top of each other to make a metal Blood Sign). However, one summoner is able to pull it out of his shadow.
    • The White Queen can shape her dress into an unlimited number and variety of weapons.

    Live-Action TV 

    Tabletop Games 
  • Dungeons & Dragons in general has had a number of spells that created weapons (usually swords). They include Mordenkainen's Sword, Dimensional Blade, Enchanted Blade...
    • Greyhawk has a few more, such as Nystul's Crystal Dagger and Jaran's Prismatic Blade.
    • Forgotten Realms adds Acid Lash, Bone Blade, Chromatic Blade, Decastave, Fellblade, Flamespin, Forcelash, Vampiric Lash, Ghost Blade, Whisper Blade, and Black Blade of Disaster. Thunderlance looks and is wielded like a spear, but doesn't act the part (it explosively discharges on touch).
      • Al-Qadim has Sand Jambiya, Sand Sword and Wind Blade.
    • Dark Sun sourcebook The Will and the Way added Psychic Blade — semi-tangible effect shaped and wielded like a sword and doubling as a mental attack.
    • In 3.5 version Psionics, the Soulknife can create a sword using psychic power. (Psychic warriors can also call weapons, but it's not clear if that's creating something or psychoporting it from some abandoned armory or what.)
    • Fifth Edition Warlocks have Pact of the Blade at 3rd level, allowing a Warlock to summon a weapon to his hand. The Warlock is proficient with the weapon while he wields it, it counts as a magical weapon for bypassing defenses, and disappears if it goes more than five feet away from him. Also doubles as a Morph Weapon, as the Warlock can reshape it into whatever form he wants in mid fight.
  • Rifts:
    • Both Cyber Knights and Mind Melters can create Psi Blades.
    • Also possible for tattooed men, as some of their magic tattoos can provide such a power; and conjurers, which also have this ability to manifest things from thin air, though they appear to be more solid than the T-mens' manifested weapons.
  • Shadowrun. In older editions, a number of fans developed spells that created a sword (or other weapon) made of energy. One type was called a "Power Sword". There have also been varieties that are made of a specific element (e.g. fire, cold, etc.) and have the appropriate elemental effect (e.g. fire setting flammable objects on fire).
  • Ars Magica. The spell "Tooth of the Staff" can create a spear with a polished flint head.
  • Mage: The Awakening: The Phantasmal Weapon spell creates a weapon, piece of armor, or other bit of functional equipment out of Mana. The Marionette spell, available at the same level of skill, can be used to create a person-or-animal-shaped construct out of Mana as well.
    • There is also the "Shadow-forge" spell, which uses different Arcana than the above (Death & Matter vs Prime) to create things out of solid shadow. It's somewhat easier to cast, but is penalized by being cast in brightly lit conditions and the objects can be damaged by light.
  • Exalts of most types are capable of creating magical weapons out of Essence, though Solars and Abyssals are generally the best at it. The other Exalts are either too specialized in the weapons they create, or prefer other methods of fighting without a weapon at the ready.
  • In Feng Shui, one of the effects for the Blast sorcery schtick is "conjured weapons".
  • The shugenja of Legend of the Five Rings can use their Elemental Magic to conjure weapons such as a katana of fire, a bo of water, a yari of air, or a tetsubo of earth.
  • Chaos Obliterators in Warhammer 40,000 can mutate their limbs into various weapons, though some depictions have the weapons already present on their arms.
  • Starfinder:
    • The basic solarion power is to spontaneously form weapons or armor in combat.
    • Fifth-level or higher technomancers can spontaneously create weapons or armor if they know the Fabricate Arms magic hack.

    Video Games 
  • The Elder Scrolls
    • Throughout the series, one can find various "Bound Weapon" spells and enchantments which temporarily summon the most powerful generic equipment in the game.
    • In the series' lore, The Ansei ("Sword Saints"), an ancient order of elite Yokudan warriors (ancestors to the modern Redguard race), were said to be able to create swords from their very souls known as "Shehai". Their highest ranks were able to use these their Shehai as actual weapons, where they were said to be an "unstoppable weapon of great might." They could even be used to perform the Pankratosword technique, in which the Ansei would "cut the atomos" with their blade. It was considered a Dangerous Forbidden Technique and is now lost to history as a result. The numbers of Ansei faded after the Redguards arrived in Tamriel, and by the 4th Era, they (and their Shehai) are considered to be myths.
    • Skyrim:
      • The aforementioned Bound Weapons have expanded functionality with the ability to banish lesser Daedra, turn undead, and capture souls after the Dragonborn gains the required perks.
      • While these weapons are very strong through the early to late-mid game, especially the Bound Bow with the Mystic Binding perk, and can grind both weapon skills and Conjuration, they have their downsides: they can't be upgraded or enchanted as they don't really exist in the Plane of Mundus, they can't be used on horseback because you can't use spells on horseback (for some reason), and sheathing the weapon dispells it so you have to be careful. The weapons can be used in conjunction with a shield but only if the shield is in your right hand, which is better than nothing.
  • Archer in Fate/stay night is able to summon his weapons out of thin air through some unknown means, unlike the other Servants who are always wielding theirs. Shirou eventually becomes able to instantly create swords from mana through his own freakish magic specialization. The exact nature of this power is complicated and takes up a great amount of expo-speak over the three routes, but it basically boils down to Shirou and Archer recording near-perfect copies of any weapon they see inside their soul and using their "Tracing" to pull the copy into the real world.
  • In the Borderlands series, any character can wield a portable arsenal (ammo included) thanks to the in-universe "Digi-struct" system, provided they have a copy of the weapon in their inventory. This is taken up a notch in future iterations, with characters like Salvador of Borderlands2 being able to dual wield on command, and Claptrap, playable in Borderlands: The Pre-Sequel!, creating cannons and turning into a small pirate ship.
  • Kassadin's Laser Blade in League of Legends is this for his Void powers.
  • Mortal Kombat:
    • The Kori Blade that Sub-Zero uses as his weapon style from Mortal Kombat: Deadly Alliance onwards is created by Sub-Zero himself using his ice-based powers. When he becomes Cyber Sub-Zero in Mortal Kombat 9, he starts creating bigger swords.
    • Frost, being Sub-Zero's protege, uses the same technique to produce her own ice weapons, though her relative inexperience means that she can only create a pair of small daggers as opposed to Sub-Zero's entire sword.
    • Nightwolf can create green energy-based daggers, tomahawks, and a bow with his powers.
    • Shao Kahn can (at least in 9) create javelins and warhammers. His ability to throw the latter is part of what makes him so dangerous: they're unblockable, can't be ducked under (so you need precise timing to jump over them or hope that your character can teleport), and stun you for several seconds — more than enough time for him to throw another one.
  • In inFAMOUS you can buy the ability to generate electric "swords" from your hands in order to do more melee damage at the cost of draining energy.
  • In BlazBlue it's implied that the Kaka Clan's claws are of this nature (as in they have the ability to produce them, rather than them being retractable). Taokaka (the only playable example of the species so far) seems to be able to produce them in a number of shapes.
  • The Unbreakable Darkness in Magical Girl Lyrical Nanoha A's Portable : The Gears of Destiny has her Ancient Matrix Limit Break, where she thrusts her hand into her opponents chest then pulls the Blood Flame Sword out from it through a dimension portal.
  • This is how all of Ultimecia's spells function in Dissidia: Final Fantasy, generating swords, arrows, axes and spears to fire at the enemy.
  • In Final Fantasy Type-0, one of Machina's unique spells is Sword Field which summons swords of Hard Light to orbit him in a Reverse Shrapnel fashion.
  • Pops up now and again in Kingdom Hearts:
  • Ghirahim of ''The Legend of Zelda: Skyward Sword does this in his boss battles, summoning fencing sabers, greatswords and a Flechette Storm with a Badass Fingersnap.
  • Impa and Sheik are all over this in Hyrule Warriors creating copies of their current weapons made from elemental energy to unleash combo attacks on enemies.
  • Shanoa of Castlevania: Order of Ecclesia can create weapons instantly by equipping the right glyphs.
  • Vergil from the Devil May Cry series Does Not Like Guns (he thinks they lack elegance) and instead creates magical energy swords that launch themselves at his enemies.
  • City of Heroes had several ice and fire themed powersets, many of which had at least one power that involved temporarily creating a sword out of either element.
  • In Castlevania: Lords of Shadow 2, Dracula can summon the Void Sword at will since the sword is simply a manifestation of the emptiness in his own heart after he forsook his humanity — it's a part of him.
  • The conjuration skill tree of Guild Wars 2 allows an elementalist to summon weaponry of various elements not only into their hands, but also at a location that they specify, so that they can pick it up after theirs runs out, or another player can pick it up and use it for themselves. Particularly helpful when the weapon in question is a Fiery Greatsword.
  • Several classes in Mass Effect 3 have omni-blades, disposable blades flash-forged by a user's omni-tool for melee combat.

    Western Animation 
  • In Avatar: The Last Airbender, Aang briefly discusses the idea of making a 'Wind Sword' this way.
  • In Wakfu, the Big Bad of season 2 can create a Sinister Scythe made of pure wakfu. After more of his true power is unlocked, Yugo is able to generate a wakfu sword and shield in the same fashion. Season 1 Big Bad Nox performs similar feats such as summoning a physical clockhand sword and a wakfu shield. During his battle with Grougaloragran, he channels a lot of power from his drones to create two huge hammers made of pure wakfu. Sadlygrove's mentor Goultard is able to summon his broken-sword-on-a-chain from his forearm. Goultard's Arch-Enemy and King of the Shushus, Rushu, can summon a huge warhammer. In some cases it's a little unclear whether they are summoning the weapons from another location or creating them on the spot.
  • All of the titular protagonists in Bravest Warriors.
  • In the animated Doctor Strange movie, the sorcerers frequently use their powers to manifest swords of magical energy.
  • Each of the Crystal Gems' personal armaments in Steven Universe simply materialize out of their gem whenever they need it. What makes this generation rather than a particular storage method is that they're clearly making new copies of the same weapon- if one is broken, just pull out another. Pearl briefly fights with two spears in Ocean Gem, and Garnet can vary the size of her gauntlets.
    Bonus points goes to the fusions, who summon the individual weapons of their constituents and then merge them into a different one. Opal builds a huge longbow out of Pearl's spear and Amethyst's whip- and then reveals she has the ability to create energy arrows for it, a different example of this same trope.
