"Ooohoohoohoohoohoo! Oh man, I canít believe all these idiots are all in the same place. Thisíll be like shooting dorks in a barrel. Ooo, but what do I use to stop Ďem? Itís gotta be perfect. Blood scythe? Hammer hand? Oo, giant spinning buzzsaw arms? A zillion tiny spikes that shoot out a zillion tiny poison darts that make your tongue swell up and youíre like, 'BLEHH, NO, BETRAYED BY OWN TONGUE! CURSE YOU DOMINATOR, CURSE YOU!'" *Choking noises* *GASP* "OO! MAGMA CANNONS, CLASSIC! YES!" *Evil Laugh*A weapon that can shapeshift into different forms for different situations. Generally magical, but can be explained with Nanomachines or some other scientific flavour of Applied Phlebotinum instead. It might be guided by magic or Electronic Telepathy, or even be an Empathic Weapon with a mind of its own. Whatever the case, it tends to be significantly cooler than any boring old stays-the-same-all-the-time weapon. A subtrope of Swiss Army Weapon. A Sister Trope to Shapeshifter Weapon when it's part of the wielder's body, Retractable Weapon when it's limited to taking a more compact form, and Adaptive Armor for its defensive counterpart.

- Black Star's weapon Tsubaki in Soul Eater has multiple forms: really big shuriken, kusari-gama, smoke-bomb, ninja blade, and, later, Demon Blade (and the several variations this mode allows). She, and the other Weapons, also counts as Equippable Allies and Shapeshifter weapon.
- Ed's arm in Fullmetal Alchemist is effectively one of these, not due to any facet of its construction, but because Ed constantly uses his alchemy to change it into various weapons, most commonly a simple blade, though he has been seen changing it into more advanced forms, such as a BFG, or even altering its chemical composition to make it more effective against certain enemies.
- Mahou Sensei Negima!:
- Negi and Albireo's book weapons. In Negi's case, he chooses an applicable name from his class register to use the pactio of. In Al's case, he uses a special book mark thanks to the sheer size of his library of names.

- The "Ultimate Weapon" is the main MacGuffin during an early story arc of Space Adventure Cobra. When finally discovered, it looks rather inconspicuous: an ovoid fitting in the palm... from which an eye open. But then, if this eye catches sight of any weapon, it can turn into a copy of it... whether a sword, a gun or a tank. And the Weapon can also turn its wielder into a freaking giant along with its own scaling up. When confronted with this, Cobra takes great care of avoiding that the Weapon could become a spaceship...
- Subverted in Hunter ◊ Hunter, where Kaito's weapon Crazy Slot, upon activation, turns into one of nine very different forms... at random.
- Flame of Recca: Kaoru's madōgu is a "puzzle weapon" and can be assembled five different ways; given how the weapon looks after the changes, how exactly this happens is unknown, as one form is basically a lance and another involve a long chain. The chain is shown to be hidden inside the Lance's shaft at one point, so most of the pieces are actually accounted for. The Bow and Arrow, however, is inexplicable on a lot of levels.
- In Naruto, one of the Seven Swords of the Mist has the ability to change its shape.
- One Piece:
- Ohm, one of Eneru's Priests in Skypiea, has a sword with an iron cloud dial (A seashell that emits clouds as hard as iron) built into the hilt. With it, he can make his blade as long as he wants to ranged attacks, or even a wall for defense.
- Diamante, an Executive Officer for the Don Quixote Pirates, at the Hira Hira No Mi, allowing him to make any object he touches as malleable as a flag without compromising their structural fortitude. He keeps several folded-up weapons on his person to use when he sees fit, and at one point folds his sword into a club shaped like a bull's head.
- In Guardian Fairy Michel, after Laura repairs it, Kim's gun can turn into a magical crossbow.
- The title armors in Senki Zesshou Symphogear come with magic-based weapons that can take on a variety of forms depending on the relic fragment that powers them.

- Black Rock Shooter / Stella, the titular character of the Black★Rock Shooter franchise can change her Rock Cannon weapon into various forms, from the typical cannon to a katana, gattling gun, a huge sword, and a spectrum-laser-firing BFG as seen in the anime.
- The offensive skills on the video game can change the equipped weapon into a homing-missile launcher, grenade launcher, hammer, chainsaw, and even a sniper rifle.
- The magic weapons in Dog Days have the power to assume whatever form the wielder desires; protagonist Cinque tends to use his as a Simple Staff because he knows Bojutsu, but he's also shown transforming it into a shield, a surfboard, and even a Frisbee. However, for some reason he can't change it into a sword until the climax of the first season, where a demonic entity goes on a rampage and threatens Princess Millhiore's life.
- Defunct comic Operation: Strikeback!'s main character Rascal had a red and white striped scarf that morphed into whatever Rascal wanted or needed at any given moment. From a frying pan to a chainsaw. Yes, a chainsaw.

- In Kyon: Big Damn Hero one of the slider's enemies is equipped with two of those. Later, Kyon and Fujiwara take hold of them.
Films — Animation
Films — Live-Action
- Hellboy II: The Golden Army: Prince Nuada has a spear that can change into a dagger and vice versa.
- The Cutlass from After Earth ; its unique design extends its sharp-bladed ends in a variety of shapes which can be chosen by the holder, each blade shape seemingly fitting a different style of attack.
- "The Soft Weapon", a 1967 short story by Larry Niven, introduced the Trope Maker; the titular "soft weapon" is a combination Sonic Stunner, telescope, Frickin Laser Gun, personal rocket, and Energy Absorber, all accessible via a sliding switch and complete with onboard AI. Hidden functions include a horizon-range Hiroshima-scale matter-to-energy converter and a Self-Destruct Mechanism.
- Iridea's Tear in The Threat from the Sea. But it's an artifact so ancient that even legends about it are mostly forgotten, a Clingy MacGuffin, it does not accepts just everyone and requires proper rite for complete binding to its new owner.
- The Great Weapon Godslayer in Dragaera. However, while she's sentient, there doesn't seem to be much logic behind the forms she uses, much to the annoyance of her wielder.
- It helps that one component in its making was an Anti-Magic chain that always became whatever length Vlad needed it to be at the time.
- One of the Sector General novels has a living continent whose only manipulative tools are silvery symbiotic organisms of organic metal, which respond to thought to reshape themselves. At close range, other sapient beings can override the vast but diffuse mental control of the landcreature.
- The Platinum Flute in the Apprentice Adept series can become any weapon or musical instrument.
- The Sartan dagger in The Death Gate Cycle not only turns itself into a weapon powerful enough to face whatever its wielder's enemies are carrying, it also changes the wielder himself if he can't handle the dagger's new form.
- For example: an elf wielding the dagger had to face another elf with a broadsword. The dagger changed into an even bigger broadsword, which was so heavy the elf couldn't hold it — so the dagger gave the elf two new arms. (This is when the elf died of shock, by the way.)
- Sometimes, if the wielder is facing an opponent more powerful than the dagger, it will actually summon something capable of defeating the opponent, rather than turning into it. As a result, a protagonist finding himself threatened by a bunch of Knight Templar demigods accidentally used it to summon a swarm of omnicidal undead, which didn't improve the situation any....
- Dom Sabalos of The Dark Side of the Sun has a "memory sword", which is essentially a hilt containing a device which can produce different types of blades, laser and molecular stripper energy weapons, or even a projectile gun that freezes bullets out of atmospheric moisture.
- The Mesmerist shiftblades in The Deepgate Codex are souls of the dead conditioned to serve as morph weapons.
- The Dark Angel Trilogy has Curoch, which can be made to change into whatever form best suits it.
- The Yuuzhan Vong amphistaff from the New Jedi Order has a comparatively mild version of this power. It can change its length, thickness, and density according to the will of its wielder, meaning that it can quickly shift from whip to spear to staff to sword and back again - and in any of its rigid states, it's durable enough to block a lightsaber. Oh, and its also a living snake-like creature, meaning that on one end (the "hilt" of its sword form) is a head with venomous fangs that can bite or spit poison, too.
- In Words of Radiance (second book of The Stormlight Archive), we find out that a true Shardblade, being wielded by its bonded Radiant, can morph into whatever shape its wielder desires, including non-bladed weapons like hammers and shields. This is because the Blades are actually spren. The ones everyone else is using are dead, but the ones the Radiants use are alive.
- Some of the keys in Keys to the Kingdom are capable of this.
- The first key, when separated into the minute and hour hand appear as daggers and knives. But when combined they fuse into a sword.
- The third key in its default form appears like a three pronged table fork, but in battle mode it changes into a full-length trident with sharpened ends.
- The fourth key which has the default form of a marshal's baton, but turns into a broadsword when Sir Thursday wields it, and into a rapier when Arthur gets into combat.
- Razors in Red Rising can be considered this.
- When not being used, it's just a relatively harmless whip. But with the push of a button, it extends, hardens, and flattens into a sword.
- The shape of the blade can even be customized mid-battle, changing from a standard sword to a curved sickle in an instant.
- Carol Berg's Rai Kirah series:
the silver Wardenís knife that could be changed to whatever weapon was needed, that could slice through the incorporeal body of a demon if you could calculate exactly where that was.—Tranformation
- Somewhither: Abby's kusarigama-like weapon has a chain that can lengthen or retract, and act as a winch to pull her and others up.
- Kamen Rider Kuuga's alternate forms can change random objects into their Weapons of Choice, with the caveat that they have to resemble the weapon in question; Dragon Form's staff and Titan Form's sword can come from any stick-like object,note but Pegasus Form's bowgun requires some form of gun.
- Kamen Rider Den-O's DenGasher consists of four pieces which can be configured into a number of different weapons, each of which is the Weapon of Choice for one of his forms, including a sword, spear/fishing rod, axe, gun, paired handaxe and boomerang, and naginata. Second Rider Zeronos' ZeroGasher works on a similar principle, but only has two forms, greatsword and crossbow. The various movie-exclusive villains tend to use unique variations on the DenGasher, to go along with the fact that most of them are made from modified Den-O costumes; the best example is G Den-O, which he wields as a gun and jutte.
- Power Rangers Lost Galaxy and Power Rangers Ninja Steel give the main five Rangers a common weapon that can turn into one of five forms, each Ranger having his or her preferred mode instead of a personal Power Weapon, but not being totally averse to changing it if the situation calls for it. Curiously, in Power Rangers Jungle Fury, Yellow and Blue have weapons that look like they're made of identical moving parts and could be switched to each other's preferred modes, and the toys definitely can, but it never happens in the show.
- The New Adventures of Robin Hood: The unicorn horn in "Devil's Bride" which can become almost anything, including a Laser Blade.
- Ka D'argo's Qualta blade in Farscape is a traditional Luxan weapon, a broadsword that can convert to a powerful pulse rifle: the blade splits to uncover the barrel, while the hilt and guard become the stock and grip.
- Dungeons & Dragons:
- Morphing is a magical ability that can be put on a weapon, allowing you to change the weapon within its size category (Light, One-Handed, or Two-Handed). However, since attack range and actual weapon properties stop becoming issues by the time you can have a +3 sword (+1 enhancement, +2 morphing), it is one of, if not the most, useless abilities in the game.
- Also available is the Rod of Surprises, which can change into one of several weapons, each being close to the concept of "decent-sized stick with a blade on one end". It has a few other functions, but those are the main ones. A DM may also allow a player to apply the Morphing enchantment as well. Since the Rod can change into at least one weapon from all three categories, the rod can now become, with a little prep time, any melee weapon ever published. Of course, all the good ones require special training, but that can be solved by taking a level in Warblade, which actually has Instant Expert as a class feature.
- Which was, of course, predated by the Rod of Lordly Might, introduced in 1E, where buttons on the rod allowed the wielder to turn it into a mace, sword, battle axe, or a spear of length between 6-15 feet. Then, there was the Rod of Lordly Might or Might Not from Dragon magazine which included the weapon form of +3 backscratcher.
- There's also the Soulknife Class, a psychic character who weilds blades of psionic energy. They begin with a short sword and later can throw it, and around 5th level they can start changing what the blade looks like, from a short sword, to a greatsword, to a bastard sword, to two short swords. With feats they can turn their mindblade into other weapons as well.
- You can also get the Sizing quality, which allows you to change the weapon's size category. Between this and Morphing, a single weapon effectively becomes every weapon ever.
- Another D&D reference, karach is an element found in Limbo which can be shaped by the strong-willed, and is used by the githzerai, who inhabit the plane (see the Planescape: Torment entry below).
- Warlocks in 5th edition who choose the Pact of the Blade get one of these as the symbol of their bond with their patron. It counts as a generically magical weapon and takes whatever form its wielder wishes, changing whenever they want — and, as part of the magic, its wielder is automatically proficient with it, allowing a warlock to casually use any weapon, even if they wouldn't be able to use the mundane version. Also overlaps with Spontaneous Weapon Creation, as it is literally shaped out the warlock's magic and dissipates back into the ether when dismissed or the warlock falls unconscious.
- The Lunar Exalted of Exalted have Moonsilver, which changes and flows constantly. One of the higher level abilities usable with moonsilver weapons is the ability to have a piece break off and burrow to the target's brain. There are also Charms that allow a Lunar to reshape a moonsilver weapon into any other moonsilver weapon they need, be it an axe, sword, or bow.
- The Phase World setting for Rifts has a race named for Japanese mythology, who use advanced nanotech to make a weapon known as the Daisho-10, a laser pistol which can transform into a short vibro-sword and back on command. Less legally, there is also a "Ninja-10" available, which also has the third form of a video camera or pocket computer (fully functional, too, to avoid suspicion).
- When Cyberknights got the Power Creep, Power Seep treatment, one of the new abilities allow them to change the appearance of their signature weapon, the Psi-Sword. Changing its shape does not change its abilities, however, and maintaining the altered shape burns up the Cyberknight's attacks per round, so its actual usefulness is questionable.
- Games Workshop games:
- In Warhammer: Age of Sigmar, the Changeling carries the Trickster's Staff, a weapon that shares its wielderís shape-changing abilities enabling it to take on the form and abilities of its opponentís weaponry.
- The Yncarne, the Avatar of the Eldar God of the Dead from Warhammer 40,000, wields Vilith-zhar, the Sword of Souls. This powerful Cronesword is able to transform into any weapon that suits the Yncarne's immediate needs, from a BFS to a pair of smaller blades, and anything in between. To reflect this, the Yncarne model can be constructed with either a single large blade or two smaller ones.
- From BIONICLE, the Toa Nuva's new Adaptive Armor and corresponding weapons automatically shape-shift to fit the environment and/or the foes they are facing. Upon teleporting into Karda Nui and finding themselves in midair, the Toa saw that their armor had already grown wings and jets; while the weapons became light-shooting "Skyblasters", perfect for battling the shadowy, bat-like Makuta that had invaded the area. It's worth noting that this is a Merchandise-Driven example; by giving the Toa shapeshifting armor, LEGO would've theoretically been able to create new figures without worrying about them looking different... if BIONICLE hadn't been canned two years later and that wave had pretty much been the last appearances of the characters.
- Devil May Cry has a number of these.
- In the first one, the Sparda weapon (the ultimate form of the humble Force Edge) works like this, changing from a sword, to a spear, to a sickle, depending on your moves.
- In Devil May Cry 3: Dante's Awakening, the electric guitar weapon can morph into a sickle when swung.
- Devil May Cry 4 has the most ridiculous example of them all: Pandora's Box, which is a rare projectile weapon version of this - turning into a bowgun, missile-launcher, minigun, laser, buzzsaw, or even a flying missile platform!
- In fact, the description of Pandora's Box claims it can take on 666 different forms, although significantly fewer are actually usable in gameplay...
- Of course, being Pandora's box the last form, 666, is Dante simply letting it drop open. If the chaos gauge is filled up this does absolutely insane damage, for logical reasons.
- Dante's Rebellion sword is cast as this in Dm C Devil May Cry. Rather than have a lot of weapons, you have a sword that is capable of tapping into Dante's Angelic or Demonic heritages, thus changing its form (and each of those states is home to two weapon configurations each that you swap between by using the direction pad).
- In Eternal Fighter Zero, Sayuri Kurata's Magical Girl wand is capable of transforming into a sword, a gun, a mace, and even a piledriver.
- The Final Fantasy series has numerous examples of these.
- The Atma Weapon (a Woolseyism of Ultimate Weapon) is a mild variation of this in Final Fantasy VI. It's always a pink lightsaber-looking sword, but it changes size (from a knife to the longest sword in the game) and attack power depending on the wielder's HP total.
- Final Fantasy XIII is filled with this. Lightning's gunblade, which is either a gun or a sword, but not both at the same time like Squall's. Sazh's matched pair of pistols can be combined together into a sniper rifle of sorts for some attack animations.
- Mog from Final Fantasy XIII-2 can change between a bow and his moogle form. Then on top of that, while in weapon form, the bow can be closed to form into a sword, in a mechanical method similar to many of the weapons from Final Fantasy XIII.
- And on top of that, we have Noel's dual swords. Aside from working as two swords (and having a built in sheath for the smaller sword on the larger flame shaped sword), they can also be combined together to form a spear/glaive, and that then can morph slightly more into a javelin form.
- Final Fantasy XIV: A large number of the Item Level 70+ gear count as these. Of particular note, is the Artemis Bow, the bard job's relic weapon. While not in combat it looks like a harp. But as soon as it's drawn, it opens up into a full sized longbow.
- Project: Snowblind has a variety of weapons, all of which have secondary fire modes that allow them to fill a role that is completely different from their primary role. Examples include a sniper rifle that doubles as a Mind Control gun, the silenced pistol that can fire smart missiles, and the ricocheting flechette gun, which could unleash a swarm of taser drones. One might say that instead of morph weapons, Project Snowblind has morph ammo.
- Neverwinter Nights
- Zig-Zagged with the Gunslashes in Phantasy Star Online 2. While most Gunslashes change form when they switch between sword and gun mode (usually by retracting the laser blade,) some are Mix-and-Match Weapons instead, keeping the same form in both modes.
- Planescape: Torment
- Dak'kon's karach blade is shaped by his thoughts; based on your conversations with him, it changes form. The Practical Incarnation reveals that he went through all the trouble of obtaining Dak'kon for the sake of his blade — apparently, only the sky's the limit for how powerful that weapon can become, if Dak'kon is focused enough.
- And there's the Entropic Blade, which can be changed into whatever weapon the PC is most skilled with.
- Soul Series:
- Necrid in Soul Calibur II has a glowing ball of Pure Energy that can become a daisho, zweihander, or battleaxe. He can also do a whip sword or simply expand the ball and smack you with it.
- The eponymous swords Soul Calibur and Soul Edge can also change form to fit their wielder. Soul Edge was originally a pair of longswords and Soul Calibur was originally a Chinese jian passed down from Xianghua's mother to her. However, Both swords' most iconic forms are Zweihanders. In most of the games, every playable character has an unlockable weapon that is either Soul Edge or Soul Calibur, morphed into whatever weapon that character uses in their personal fighting style.
- World of Warcraft
- Certain Epic quality weapons (before the expansion pack) used to be Morph Weapons (Benediction-Anathema is a good example). This mechanic is no longer used, however, due to problems with enchanting such items.
- Another system was introduced instead, the heirloom items. These items can be passed between any character on the same account and server and scale with the characters level. Some of them even change armor type to cover the fact that several classes get a new armor type to use at level 40 (leather->mail and mail->plate).
- There's also (with the second expansion) Quel'Delar. Okay, it's always a sword, but in game terms what's far more important is that when it is finally gained after a long quest chain, it "adapts to its wielder" and you can choose what stats it has, which matters more than the actual physical shape it takes. (But if you can't use a sword at all, you'll get a different weapon of equal power from the Argent Crusade's arsenal.)
- Iji: The Komato GEN2 Pre-Loader uses nanotech to assemble its ammo on the fly, allowing its wielder to open fire with anything — from machineguns to death beams to the MPFB Devastator — with absolutely no warning beforehand. The same can be said of the Tasen replica wielded by the protagonist herself.
- Kingdom Hearts
- Keyblades do this in two different ways - first, swapping keychains gives it a new "look" based on a certain world or character, with different bonuses in terms of strength / reach / magic. When the Birth by Sleep characters showed up, things started getting wilder.
- Lingering Will's Keyblade changes from a BFS, to a whip, to a bow and arrow, to a giant cannon, to a HOVERCYCLE! Seriously.◊ Terra, by contrast, can only use the cannon and cycle modes as a playable character.
- Keyblades in general can do this, although only the Birth By Sleep characters and Sora as of Kingdom Hearts III know how to do so. Each Keyblade seems to have certain extra shapes based one or two specific keychains - Terra's bike / cannon / etc are all based around either Earthshaker or Ends of the Earth, whether or not he's actually using them at the moment.
- In the Final Mix version of Birth by Sleep, the new bonus boss No Heart, the data of Master Xehanort in his prime, can change his Keyblade into shin guards, a large claw, an arm cannon, a floating shield and even a large pair of wings.
- Kingdom Hearts III takes this and really runs with it - all of Sora's keychains have their own unique transformations.
- Jak and Daxter: Jak's Morph Gun. Really, the name says it all.
- Zero's Z-Saber in Mega Man Zero can also be a spear, grappling hook, tonfa, magazine for a pistol, or shield you can throw.
- While the weapon itself doesn't change, Mega Man's Arm Cannon can fire a variety of different weapons thanks to the weaponization of his Variable Tools System. In the sequel series, Mega Man X, X's X-Buster does much the same, but, when he gets the inevitable X-Buster upgrade, he can also charge the weapons to get entirely different effects (such as Chameleon Sting, which is stated to fire powerful optic lasers, making him functionally invincible when it's charged up).
- In Mega Man Star Force, all of your Battle Cards manifest by morphing your Mega Buster into a sword, variant gun, or other weapon. It's just as well that Omega-Xis is a bit of a Blood Knight, since the Mega Buster in the Star Force games is his head.
- Mana Khemia: Alchemists of Al-Revis
- The main character, Vayne, has his cat transform into a sword and armor. And then it further transforms into an even larger sword, among other things...
- And in the sequel, Mana-Khemia 2: Fall of Alchemy, both of the main characters transform their weapons during their Intimate Strikes. Raze transforms his sword of light into a spear, and Ulrika transforms her morning star into a spiked hammer.
- Jude's ARM in Wild AR Ms 4, "Shapeshifter", typically takes the form of a one-handed pistol, but can also transform into a sword or a two-handed beam cannon, among other things.
- For once Peter Molyneux wasn't lying when he said weapons in Fable III will alter their shape depending on what you slay with it. Whether there was any actual point to this system however...
- Your Silent Protagonist in God Eater Burst wields a weapon which shifts between a BFS and BFG at the push of a button.
- From the Guilty Gear series there's Millia Rage and her hair. Technically, her hair is alive (long story) and she can use it as a weapon by changing its shape and density at will. Millia can turn it into a blade or shield herself with it, and can shoot a projectile from it, among many other things. Her ultimate kill move has her hair locks impale the opponent. Twice.
- Technically, the Noble Phantasm of Lu Bu, Rani's Berserker in Fate/EXTRA is one of these. The NP can switch between five different forms, however, because Berserker is under Mad Enchantment, he doesn't have enough frame of mind to use it to its full potential. The only forms he can use in the game are a pike and a bow that launches said pike as the arrow. The other three forms are a mystery.
- The Scions in BattleZone II have shapeshifting Hover Tanks. Combat mode is faster, more maneuverable and regenerates ammo, while Assault mode is more damage-resistance and regenerates health (slowly). The weapons on the tanks likewise shift between Combat and Assault mode; Combat is best suited for fighting other ships, while Assault mode is better at attacking bases or high-end units. The Scion's Arc Cannon for example, goes from firing a long-ranged 5-shot lightning burst in combat mode to a continuous short-ranged lightning arc in Assault mode. International Space Defense Force weapons also have combat/assault modes, but their units are incapable of morphing, forcing them to rely on other units to get the alternate modes.
- League of Legends: Jayce's Weapon of Choice is the Mercury Hammer/Mercury Cannon. Changing the form of the weapon also changes Jayce's whole move set, giving him the ability to transform from Close-Range Combatant to Long-Range Fighter at will.
- The Elder Scrolls:
- Bound weapons in the series becomes this to the player. Players with a high enough conjuration skill are never without a weapon. (Or minion!)
- In The Elder Scrolls IV: Oblivion's Shimmering Isles expansion, players could acquire the sword Dawnfang/Duskfang, a blade that changes appearances and elemental alignment (fire and ice) at 6 AM and PM, it was also a bloodthirsty Empathic Weapon that will grow stronger on the next transformation if you kill twelve enemies with it.
- Later entries of the Monster Hunter series have the Switch Axe weapon class, a "high-tech" armament that can transform using a special phial from a massive axe into a massive sword. Also, the upcoming Monster Hunter 4 has another transforming weapon class, the Charge Axe, which adds a separated sword-and-shield form to the mix.
- Vanquish's Battlefield Logic ADaptable Electronic weapons system(BLADE) not only transforms into up to three different weapons on command, it can store itself in Sam's arm. How does it work? Who cares?
- In Shounen Kininden Tsumuji a Japanese game, has Tsumuji's weapon a large shuriken is able to transform into different weapons against enemies after gaining power stones.
- In Bloodborne, Trick Weapons are the main offensive option for players. These weapons tend to have fairly orthodox normal forms, but can transform into wildly varying alternate forms. This is an odd case, though, as most Trick Weapons are at least seemingly possible in real life(Ex:a hand-saw with blade folded inward towards the handle that can fold out into a large cleaver).
- Eckesachs, the weapon wielded by the Big Bad Zephiel of Fire Emblem: Binding Blade, usually takes the form of an imposing Staff of Authority, befitting its holder's position as king. When he actually uses it in combat, it transforms into an absolutely massive sword.
- Axiom Verge: Trace's Axiom Disruptor can morph into various different weapons (such as an ice-thrower or a Lightning Gun), as well as project a laser drill, corrupt enemies, and create a remote drone.
- The Bayonetta series has the Rodin, weapons that are earned by beating the Fallen Angel of the same name in a brutal Bonus Boss battle. In the first game their default form are four golden rings that look like halos that can morph into any of the various angelic weapons that can be temporarily obtained throughout the game (plus a chainsaw). In the sequel the wrist rings are are now crimson red, and will morph exclusively into demonic weapons, while the golden ankle rings retain the ability to morph into angelic weapons.
- The Final Boss of Dark Souls III, the Soul of Cinder, is a manifestation of everyone who has ever linked the First Flame, including every Chosen Undead and Bearer of the Curse who chose to do so across countless player worlds, and he has the variety to show for it. His weapon can turn into a straight sword, a curved sword, a lance/halberd, and a sorcery catalyst. And once his health is depleted, Gwyn and his greatsword come back for a rematch.
- Uncle Death's Scythe from Let It Die is able to retract the blade, transforming into a golf club.
- Kinessa's gun from Paladins needs less than a second to transform from assault rifle to sniper rifle or vice versa.
- The Shining Trapezohedron from Sundered is an intelligent shapeshifting crystal that attacks by coiling around one of Esheís limbs and shaping itself into a variety of different blades, fists, and spikes as she swings it around. Its ability to do this is justified by the fact that it is part of an Eldritch Abomination.
- In the Feast Master story arc of Banana-nana-Ninja!, the Omni-Functional Kitchen Gadget can turn into a variety of cooking utensils and appliances, as well as a Humongous Mecha used in the final battle.
- RWBY, quite famously so. The Heroine Ruby's Crescent Rose can transform between a BFG and a Sinister Scythe. The Smart Guy Blake's Gambol Shroud can transform between a ninja sword and a machine pistol. The Ace/HeroineOfAnotherStory Pyrrha Nikos has a weapon that can transforms between a short Greek-style sword, a spear, and a long rifle. And Ineffectual Sympathetic Villain Junior has a huge missile launcher that can transform into a hefty baseball bat. It's actually at the point where it's unusual to see a weapon that doesn't transform in some way.
- In Darken, there's Shard, a sentient, evil sword, who can change himself into whatever form of weapon is most advantageous. Although he's more likely to change into whatever's funny...
- Secret's weapon in Keychain of Creation is one of these, as well as an Empathic Weapon with a taste for blood — including the wielder's. Yikes.
- The title character's sceptre in Gorgeous Princess Creamy Beamy. It's supposed to be only able to morph into various eating utensils, but she managed to get around this with her warped logic; "A sawblade could be an eating utensil!"
- Beisaru's staff, in Juathuur, can get longer. And sharper.
- Fiona's weapon in Supernormal Step manifests a variety of shapes out of its apparently-fixed handle. So far she doesn't seem to have much control over its shifting.
- In Axe Cop, Fire Slicer has a sword that can turn into a torch and then back into a sword, so he can set his opponents on fire while he's cutting them in half.
- Wildcard, the sword-of-a-million-tricks from Tales of the Questor, made this trick number 1,000,001, debuting this new ability by lobotomizing a dragon. OUCH.
- Homestuck: Kanaya, Jane, Calliope, and Caliborn all wield weapons which are capable of morphing: Kanaya wields a lipstick which becomes a chainsaw, Jane wields a cutting-edge Betty Crocker spoon which becomes a fork with the flick of a button, Calliope's wand transforms into a magnum pistol, and Caliborn's scepter turns into a rifle. Kanaya's in particular is a callback to Problem Sleuth, where object/weapon duality was a running gag.
"Your KEY is out of bullets!"
- Darius in The Cyantian Chronicles got a somewhat high tech "stick" for his 15th birthday.
- APT Comic: Ammika's locket. It's a sword! It's a flail- er, mace! It's a cat!
- Green April from Tower of God, a hook-like baton that can grow into a giant whip and also splits into several sub-branches.
- In The Story of Anima, How Dante's Animus manifests. Its base form is a black fluid that he can shape into the desired weapon, from a scythe to a monster-sized guillotine.
- Of the funny variant; in the Van Beuren Studios Tom & Jerry note short "Rabid Hunters", Tom corners a rabbit, first pulling out a handgun, but then he turns it into a hunting rifle on the spot.
- The Lotus Blade in Kim Possible.
- Yang's bamboo sword in Yin Yang Yo!
- Featured in one of Oh Yeah! Cartoons more cinematic shorts.
- Xiaolin Showdown does one of these with Omi's Shimo Staff.
- There is a transforming sword in the old Teenage Mutant Ninja Turtles cartoon. Splinter is the only ninja skilled enough to wield it; otherwise, it sprouts extra blades and such uncontrollably.
- She-Ra: Princess of Power:
- She-Ra's power sword can change shape when she says the phrase "Sword to <desired shape>".
- Her friend Bow's... bow can change into a lute whenever he wants to sing a song. This doesn't come up very often, thankfully.
- And let's not forget Hordak, who can shapeshift his own body into any kind of weapon needed.
- Inspector Gadget's hat can function as one when it deigns working right.
- The Star Trek: The Animated Series episode "The Slaver Weapon" involves Spock, Sulu and Uhura held captive by a crew of Kzinti (the episode was written by Larry Niven, adapted from his own "The Soft Weapon") while carrying a case of artifacts from a long-lost race called the Slavers. One of the artifacts turns out to be a hand-held weapon that can change form with a twist of a dial, from an energy pistol similar to a phaser, to a telescope, to a vocalizing computer, to a long-range weapon that carries the impact of a small nuclear bomb. Fortunately for the rest of the galaxy, it also has a self-destruct (which the vocalizing computer tricked the Kzinti into triggering). Sulu hypothesized that the device was used for espionage instead of combat, since the average grunt wouldn't need all those settings.
- Guardian Keytools from ReBoot (Also a Green Lantern Ring), such as Bob's Glitch.
- Galtar and the Golden Lance: The title weapon is somewhere between this trope and Swiss Army Weapon as it starts off as a stick that looks like a pair of collapsed pummels, extends into a double-sword/lance, can bifuburcate into a pair of swords, or recombine into a more powerful sword.
- The Bayard sidearm from Voltron: Legendary Defender, which goes from a knuckleduster-like standby mode, to a Hard Light projected weapon fit for its Paladin wielder. Big Bad Emperor Zarkon, the original Black Paladin ten millennia back, kept his Bayard when he betrayed his team. He's shown to be able to access multiple weapon modes, including (but likely not limited to) a cutlass, energy shield, BFG, chain whip, giant mace, and BFS!
- Transformers: Robots in Disguise has Decepticon Hunters, able to take the form of any weapon the wielder can think of. Each of the team has his or her preferred mode, but will use other forms as needed.
- Lord Dominator from Wander over Yonder can morph the gloves on her armor into any sort of weapon she desires, but usually sticks to just shooting blasts of lava and icicles later on. In 'The Battle Royale', she contemplates about what one to use to make her grand entrance (quoted above).
