* The zanpakuto in ''Manga/{{Bleach}}'', for Soul Reapers who have learned to release their upgraded forms, Shikai and Bankai. In their sealed form, most zanpakuto take the form of a katana, and usually will transform into a larger weapon in Shikai form, and then then into something even bigger in Bankai form, but this is not always the case. A few don't change form at all and simply reveal new powers in Shikai and Bankai. For example, Renji's Zabimaru transforms from a Katana into a WhipSword, and as Hihio Zabimaru becomes a gigantic snake skeleton.

* There is a transforming sword in the old ''[[WesternAnimation/TeenageMutantNinjaTurtles1987 Teenage Mutant Ninja Turtles]]'' cartoon. Splinter is the only ninja skilled enough to wield it; otherwise, it sprouts extra blades and such uncontrollably.

* ContinuityReboot ''WesternAnimation/SheRaAndThePrincessesOfPower'' retains the shapeshifting nature of She-Ra’s sword, but she just has to ''will'' the sword to change shape now. It takes her a while to get the hang of it, in the process discovering that its list of forms includes things like “coffee mug” and “flute” for some reason.

* The ''WesternAnimation/StarTrekTheAnimatedSeries'' 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 "Literature/TheSoftWeapon") 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 ''WesternAnimation/ReBoot'' (Also an ArtifactOfPower), such as Bob's Glitch.

* Lord Dominator from ''WesternAnimation/WanderOverYonder'' can morph the gloves on her armor into any sort of weapon she desires, but usually sticks to just shooting blasts of lava [[spoiler:and icicles later on.]] In 'The Battle Royale', she contemplates about what one to use to make her grand entrance (quoted above).
* Some witches in ''WesternAnimation/TheOwlHouse'' use abomination magic this way, shaping various weapons from the same slime typically used to form a MuckMonster.

* Of the funny variant; in the Creator/VanBeurenStudios Tom & Jerry [[note]]No relation to the [[WesternAnimation/TomAndJerry famous cat and mouse duo]][[/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.

* ''Manga/{{Mar}}: The characters fight using magical objects called Ärms. Ärms usually take the form of jewelry, and many of them, especially weapon and guardian Ärms, change into something else when they are activated. Babbo is a unique Ärm who is animate even when he hasn't been activated and also has the special power of being able to transform into anything that his user imagines, with the limitation that his transformations have to be programed into magic stones placed in him. In his normal form he is a metal ball with a face chained to a hammer, resembling a Kendama, with the ability to change size. As more magic stones are added to him, Ginta imagines more forms for him to turn into. His first transformation turns him into a metal boxing glove that can also change shape into a dagger (which kind of cheats the limits of how many forms he can have), his second transformation is a gun that fires explosive bubbles, and his third transformation is a huge gargoyle with a powerful BreathWeapon, and even more forms are added through the story.

* The [[ScaryDogmaticAliens Yuuzhan Vong]] amphistaff from the ''Literature/NewJediOrder'' 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''. [[LivingWeapon 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 ''Literature/WordsOfRadiance'' (second book of ''Literature/TheStormlightArchive''), we find out that a true [[AbsurdlySharpBlade Shardblade]], being wielded by its bonded Radiant, can morph into whatever shape its wielder desires, including non-bladed weapons like hammers and shields. [[spoiler:This is because the Blades are actually [[NatureSpirit spren]]. The ones everyone else is using are dead, but the ones the Radiants use are alive]]. In Literature/{{Edgedancer}}, we find out that they don't have to be weapons per se, though apparently any points will still be {{Absurdly Sharp Blade}}s which makes a Shardfork [[AwesomeButImpractical impractical]] as an eating utensil. And [[spoiler:Lift's spren]] really doesn't like hurting people, so that Shardblade will only turn into a staff in combat.

** 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.

* Creator/CarolBerg's ''Literature/RaiKirah'' series:
--> the silver Warden’s knife that could be changed to whatever weapon was needed, [[WeaponOfXSlaying that could slice through the incorporeal body of a demon if you could calculate exactly where that was]].
--->--''Tranformation''

** ''Series/HimitsuSentaiGorenger'': Each of the Gorangers have a weapon or tool they can summon by pulling off the outer layer of visor from their helmet, which then transforms. Some of them have multiple forms that their visor weapon can take. Akaranger's visor weapon normally is a whip but he occasionally turns it into a spear and he has also turned it into a drill, a net, and a claw. The Goranger's finishing move, an explosive ball that they pass around to charge it up, is eventually upgraded to have the power to transform into something the target is weak against.

* ''Series/SeijuuSentaiGingaman'' (and by extension ''Series/PowerRangersLostGalaxy'') 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.
* ''Series/JukenSentaiGekiranger'' has Geki Blue and Geki Yellow both wielding the Geki Tonfa, which can be used as a pair of dual-wielded tonfa or combined together into a single bo staff called the Geki Tonfa Long Baton. Curiously, in ''Series/PowerRangersJungleFury'', the Blue Ranger only uses the Jungle Tonfa and the Yellow Ranger only uses the Jungle Bo, never switching between the two forms or even it being implied that they are the same base components in the show despite it being a single toy.
* ''Series/ShurikenSentaiNinninger'' gives the team the Karakuri Hengen, a shuriken-shaped weapon that can become a blade, bow, or claw. ''Series/PowerRangersNinjaSteel'' gives the weapon an extra function by turning it into the season's TransformationTrinket[[note]]In ''Ninninger'' the Rangers transform with their {{Cool Sword}}s, but Bandai asked Saban to change it [[MerchandiseDriven to sell more toys]][[/note]].
* ''Series/UchuSentaiKyuranger'' operates on the same principle as Den-O above with Kyu The Weapon, the primary weapon for the core team. It consists of three parts (a sword blade, an axe blade, and a grip/beam gun) that can be configured to produce a total of nine different weapons. {{Sixth Ranger}}s Ryu Commander and Hou'ou Soldier each have their own unique weapons, while quasi-Sixth Koguma Skyblue just uses the same weapon as his BigBrotherMentor Sasori Orange.

* ''Fanfic/TheMountainAndTheWolf'': The Wolf takes away Jaime's golden hand and returns it able to morph into whatever Jaime wants, including growing spikes to stab an attacker's arm, then a piercing tentacle to get at said attacker's heart, and also funtion as a normal hand. From the context it's probably been possessed by a Slaaneshi daemon.

** BigBad Emperor Belos can also do the same in his cursed state, morphing his own arms into blades and axes
** Jean-Luc can do this too.
