** 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!

* When dueling Touma in ''Manga/ACertainScientificRailgun'', Mikoto Misaka uses electromagnetism on the sand and dirt around her to create a WhipSword out of iron sand.
** Harumi Kiyama briefly draws an energy blade while fighting Mikoto.
* Spike the Devil Man from ''Manga/DragonBall'' used his [[FunctionalMagic magic]] to create a pitchfork.
** Later on in ''Manga/DragonBallZ'', Dabura used magic to create a sword and a spear.

* The Pandora from ''Manga/{{Freezing}}'' does this with their Volt Weapon.

* Cures Rouge, Lemonade, Mint and Aqua of ''[[Anime/YesPrettyCure5 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 ''Anime/SmilePrettyCure'', Cure Beauty can make an ice sword, which she used to fight Joker.

[[folder:Fan Fiction]]

** In ''Film/{{Thor}}'' the [[AnIcePerson Frost Giants]] can form weapons out of the ice covering their body.

* Series/KamenRiderGaim's SuperMode, Kiwami Arms, allows him to summon the weapons used by any of the other Armored Riders out of thin air; in addition to wielding them normally, on a few occasions he simply [[ThrowingYourSwordAlwaysWorks launches the weapons telekinetically]] at his enemies.

* In ''Series/PowerRangersTimeForce'': [[BigBad Ransik]] has the power to pull swords and other knife-like weapons out of his body, meaning he's never unarmed. The crossover special in ''Series/PowerRangersWildForce'' reveals he got this power from three Orgs that he set free in the year 3000.

* Kassadin's LaserBlade in ''VideoGame/LeagueOfLegends'' is this for his Void powers.

* In ''VideoGame/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.

* This is how all of [[VideoGame/FinalFantasyVIII Ultimecia's]] spells function in ''VideoGame/DissidiaFinalFantasy'', generating [[StormOfBlades swords]], [[RainOfArrows arrows]], axes and spears to fire at the enemy.

** Vergil DoesNotLikeGuns (he thinks they lack elegance) and instead creates magical energy swords that launch themselves at his enemies.
** In ''VideoGame/DevilMayCry5'', [[spoiler: Dante's new sword can conjure four swords to attack on his behalf.]]

* This is a power ''VideoGame/SoulSeries'' BigBad Inferno has. As he is able to recall any memory of those who came in contact with Soul Edge, he can summon the weapon form they used when he used their body. In gameplay, this means he is a DittoFighter and can replicate any fighter's attacks while also having several exclusive moves. When he was forced to reside in the Nightmare armor during ''III'', the weapon he uses is a fabricated version of Soul Edge (when ''IV'' rolls around he is using the actual Soul Edge instead).

* Archer in ''VisualNovel/FateStayNight'' 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, [[spoiler:but it basically boils down to Shirou and [[FutureBadass 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]].

* ''Webcomic/DemonHunterKain'': Kain's knives.

* Clerics (or "[[InsistentTerminology holy persons]]") in ''WesternAnimation/TheLegendOfVoxMachina'' seem to prefer this as a default, no doubt an in-universe usage of their "spiritual weapon" spell from the games. Pike uses hers for a mace and shield, Kashaw creates spears. All out of the same glowing energy, all out of thin air.
** There's also Scanlan's creative use of "[[WritingAroundTrademarks Scanlan's Hand]]" as a weapon, conjured up by his singing and made out of purple energy.

** Cinder's Semblance, Scorching Caress, allows her to manipulate the shape of superheated objects such as glass, or even the powerful [[AppliedPhlebotinum Dust]]. She typically uses it to create [[BowAndSwordInAccord a bow and dual swords]] called Midnight out of Dust. However, [[spoiler:she is only capable of superheating materials due to [[PowerParasite absorbing]] half of the [[PersonOfMassDestruction Fall Maiden's]] power. Before that, Midnight was a more mundane MixAndMatchWeapon]].

** In ''VideoGame/KingdomHeartsII'', Sora and Riku can summon swords of darkness and light to encircle them ReverseShrapnel style with their XIII Blades skill during their CombinationAttack Limit Break.

** Student Council President Shizuru Fujino, who lives by TeaIsClassy, dresses in kimono when not in school uniform, and speaks in a ''[[JapaneseDialects Kyoto-ben]]'' summons a WhipSword version of [[NaginatasAreFeminine a naginata]].

** Student Council President Shizuru Fujino, who lives by TeaIsClassy, dresses in kimono when not in school uniform, and speaks in a ''[[KansaiRegionalAccent Kyoto-ben]]'' summons a WhipSword version of [[NaginatasAreFeminine a naginata]].

** Student Council President Shizuru Fujino, who lives by TeaIsClassy, dresses in kimono when not in school uniform, and speaks in a ''[[KansaiRegionAccent Kyoto-ben]]'' summons a WhipSword version of [[NaginatasAreFeminine a naginata]].

** Student Council President Shizuru Fujino, who likes ASpotOfTea, dresses in kimono when not in school uniform, and speaks in a ''[[KansaiRegionAccents Kyoto-ben]]'' summons a WhipSword version of [[NaginatasAreFeminine a naginata]].

** Student Council President Shizuru Fujino, who likes ASpotOfTea, dresses in kimono when not in school uniform, and speaks in [[KansaiDialect a Kyoto-ben]] summons a ChainWhipSword version of [[NaginatasAreFeminine a naginata]].

** Circus stores a [[DropTheHammer sledgehammer]] in an [[{{Hammerspace}} extradimensional space]], allowing for what appears to be this trope.

** ''Hitman'' #1,000,000, the ''ComicBook/{{Hitman}}'' issue tying into and sending up the ''ComicBook/DCOneMillion'' 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*

* As of her solo series, ComicBook/JeanGrey manages to do this, if entirely by accident, while fighting orcs alongside [[StealthMentor 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.

* Deceased ''ComicBook/SpiderMan'' villain Demogoblin has [[PlayingWithFire the ability to project and manipulate]] {{hellfire}} as an inherent trait, due to being a demon. Whilst certainly capable of projecting fire in more straightforward manners, he preferred to create flaming constructs in the shape of the [[ComicBook/NormanOsborn Green Goblin]] paraphernalia, most notably a bat-shaped "hoverboard" made of solid flame, razor-edged bat-like fiery projectiles, and exploding fireballs in the shape of flaming jack-o-lanterns.

[[folder:Fanfiction]]

* In ''VideoGame/BlazBlue'' it's implied that the [[CatGirl 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.

* In ''Fanfic/TheHillOfSwords'', naturally this is [[VisualNovel/FateStayNight Shirou]]'s shtick with his tracing, though [[LightNovel/TheFamiliarOfZero Guiche]] gets in on it, too. Shirou eventually performs the logical conclusion of this trope by pulling out [[FieldOfBlades Unlimited]] [[StormOfBlades Blade]] [[HyperspaceArsenal Works]].

** Hibiki, uniquely, ''cannot'' summon [[BladeOnAStick 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 [[CursedWithAwesome a blessing in disguise]]. Her true Armed Gear, as she puts it, is [[BareFistedMonk her own hands]] - because she doesn't hold a weapon she's free to [[ThePowerOfFriendship hold hands]] [[CombinedEnergyAttack with others]]. She does gain the ability to summon an Armed Gear later, but she prefers to form it into a giant gauntlet rather than the standard spear.

* The shugenja of ''TabletopGame/LegendOfTheFiveRings'' can use their ElementalPowers to conjure weapons such as a [[FlamingSword katana of fire]], a [[MartialArtsStaff bo of water]], a [[BladeOnAStick yari of air]], or a [[CarryABigStick tetsubo of earth]].

* This is how all of [[VideoGame/FinalFantasyVIII Ultimecia's]] spells function in ''VideoGame/DissidiaFinalFantasy'', generating [[StormOfBlades swords]], [[RainOfArrows arrows]], axes and [[BladeOnAStick spears]] to fire at the enemy.

* Void in ''Webcomic/LsEmpire'' can make [[BladeOnAStick spears]] pop out of his body. His [[FutureBadass future self]] can make them on any surface.
