History Main / LivingWeapon

* AttackAnimal - Trained creatures.
* BioweaponBeast - Genetically engineered creatures to serve as weapons.
* EquippableAlly - Other characters who are picked up and wielded as weapons (possibly after transforming into one).
* HumanWeapon - A weapon that is specifically a human being ([[HumanoidAlien or human enough]]).

* Senketsu and Junketsu from ''Anime/KillLaKill'', and to an extension all Goku Uniforms. While Junketsu never does more than growl and snarl in a [[TheBerserker mad rage]], Senketsu is completely sentient, and is not only able to speak (though only Ryuko can hear him), but also move on his own.
* An Amanto (alien) couple in the forms of [[SexComedy a katana and a scabbard]], from ''Manga/{{Gintama}}''. The katana wants to get back his wife and he keeps [[AssShove sticking in Gintoki's ass]] until he agrees to help him.
* The EVA units from ''Anime/NeonGenesisEvangelion''. They are [[spoiler:{{Eldritch Abomination}}s with {{restraining bolt}}s tightened on them to keep them in control. Once that armor goes off, [[TheBerserker watch out]]. To make them sync with the pilot, the people who make the [=EVAs=] have to bond a soul of their mother to the EVA, though the details aren't exactly clear, with one unit having the entirety of the soul, another just having part of a soul, and another just having a clone's soul. In any case, if the pilots come to harm, ''especially'' if it's Shinji, [[MamaBear watch out]]]].

* An interesting example is Crona and Ragnarok from ''Manga/SoulEater''. The result of a witch's experiment, Crona had all of [[AmbiguousGender hir]] blood replaced with a substance called "Black Blood" (not 'that' BlackBlood) that was created in part by melting down the EquippableAlly Ragnarok. The result is a mentally unstable TykeBomb [[BloodyMurder whose weaponized blood]] has its own distinct personality.
** Half the characters can willingly transform into weapons; some can actually move somewhat independently or just transform body parts into weapons if they don't have a meister to fight with. This came about as the result of another witch's experiment centuries earlier (the sister of the witch who created Crona and Ragnarok, at that), and now many of the descendents of her test subjects have inherited the ability to transform into weapons.
* Baby 5 from ''Manga/OnePiece'' ate the Weapon Weapon Fruit (Buki Buki no mi), allowing her to both form weapons from her body parts and/or turn herself into large weapons including torpedoes (she can reform after the explosion), scythes and swords.
** There have also been several examples of weapons that have 'eaten' a Zoan Devil Fruit, and gaining the ability to transform from weapon form to animal form, with enough intelligence to follow orders from their owners and on one occasion threatened. These examples include Spandam's sword Funkfreed, which ate the Eleph-Eleph Fruit (Zou Zou no Mi). The other prominent example is Lassoo, a bazooka like gun that 'ate' the Mutt-Mutt Fruit, Dachshund Type (Inu-Inu no Mi) and has the ability to transform between dog and gun form, in the same style as Funfreed.
* In ''LightNovel/{{Katanagatari}}'', practitioners of Kyotouryuu like Shichika have it indoctrinated into them from an early age that they are swords, not swordsmen. They aren't supposed to think for themselves and should only attack what their "wielders" want them to attack. A big part of Shichika's CharacterDevelopment throughout the series has him realizing that he is [[IAmNotAGun more than a sword]].
* The Protoculture of ''Anime/{{Macross}}'' seemed fond of this sort of weapon. The most obvious example is their ServantRace, the Zentraedi, created so that the Protoculture would have super-soldiers to order around. There's also the [[Anime/Macross7 Evil Series (which became the Protodeviln)]], each of which was a living superweapon with sufficient power to rend a planet in half. There's also that [[Anime/MacrossZero bird-human thing]] they left sleeping on Earth.

* ''Manga/BlackCat''. Creed's Imagine Blade is one in its Level 2 [[spoiler:or higher]] state. If the face and the fact it occasionally cackles aren't enough of a clue, Creed explicitly says it's alive and has a [[{{Synchronization}} mental connection]] with him, to the point that breaking the Imagine Blade would break his mind.

* The Cloths from ''Manga/SaintSeiya'' are living ''armor'', their status as living beings granting them self-repair abilities, enough sentience to accept or reject a wielder (as most dramatically seen when the Cancer Cloth grew so disgusted with its user Deathmask it abandoned him mid-battle), and the chance of evolve under certain circumstances. Unusually, it's also shown that the Cloth's nature as living armor has the downside they can just ''die'' if damaged too much, hence the existance of two Cloths that include tools to repair and revive "dead" Cloths (or just plain execute maintenance, as the self-repair is slow and has trouble keeping up with continuous use)-[[ThePowerOfBlood with the help of a generous dose of blood from a Saint or a divinity]] (blood is not necessary to repair still living Cloths, but can be useful for improvements if the donor is a Saint of greater rank than the Cloth or even a god).
** {{Subverted}} with the Black Cloths: while considered Cloths and built out of the same base materials, the creators didn't know the whole process and couldn't make them into living weapons. Or as tough as even Bronze Cloths.

* ''Manga/SoulEater'' basically runs on this trope: "Meisters" are individuals who wield other individuals as "Weapons"--who basically look like people until they transform into their weapon form.
* ''LightNovel/KyoKaraMaoh'' has Morgif, the legendary demon sword with a personality. He seems to be neigh immortal, and can talk in theory although nothing he says is ever intelligible.

* ComicBook/BuckyBarnes as the Winter Soldier became this, transformed into a nightmarish and implacable assassin by the Soviets (implied to be the Red Room, the same people who produced the Black Widows), a myth of the Cold War. He was given a metal arm to replace his crippled left, and had everything but his language skills and combat training removed, before being cryogenically frozen and defrosted for missions.
* The current page quote, from the ComicBook/AmalgamUniverse, talks about Dark Claw's (Batman/Wolverine Amalgam) greatest nemesis "Hyena" (a fusion between ''Sabretooth and ComicBook/TheJoker''). You can guess how much of a bad idea '''that''' turned out to be in the long run.
* In ''ComicBook/BuckGodotZapGunForHire'' the Beemahs were bioengineered as essentially walking rat-sized blasters. Their creators were wiped out and there's a "shoot on sight" order out for Beemahs themselves.
* ''ComicBook/SupremePower'': The PowerCrystal that came inside Hyperion's ship is alive and sentient, and is used as a weapon by Joe Ledger, aka Doctor Spectrum.

*** The Green Lantern Ring of Alan Scott has a personality of its own, sufficient that it and Strange can confer, and it has opinions on people - it takes a liking to [[spoiler: Carol]], for instance.

*** Ván, the ancient sword of Frey, forged of Uru and Vibranium and more or less every enchantment that the desperate Alliance of Realms could throw at it, developed one astonishingly quickly - as in, it immediately lodged itself in the oak tree that represented Yggdrasil and refused to move until a worthy wielder appeared to claim it. Every immediately suspects Strange, who was actually involved in events, but he [[NotMeThisTime says it wasn't him]] and notes that he was as confused as everyone else.

*** The Winter Soldier was designed to be this, a ruthless assassin and when needs be, a OneManArmy capable of singlehandedly mowing through entire squads of Aurors, defeating Captain America, the Black Widow, and Clint Barton simultaneously, killing a werewolf the size of a hummer with his bare hands, and stalemating ''Wolverine'' in a KnifeFight while carrying multiple broken ribs. There is a ''reason'' that people are terrified of him. However, a persistent streak of free will meant that he kept having to be [[MindRape brainwashed into obedience]] - and even ''that'' couldn't remove an unwillingness to hurt children if it was at all possible to avoid it (to the point where the Red Room just stopped bothering to order him on those missions as they had other assets, and HYDRA ignoring that actually triggers a temporary HeelFaceTurn).
*** The Red Son was a project designed to create the Winter Soldier's SuperiorSuccessor. When it's implemented by the revived Red Room in the sequel, they enhance a PersonOfMassDestruction, rather than a latent SuperSoldier, and successfully turn them into a BlankSlate, rather than an amnesiac. The results are utterly horrifying - partly because of the sheer devastation the Red Son causes, partly because [[spoiler: it's Harry]], partly because the enhancements include - instead of a bionic arm - the Techno-Organic virus, and partly because when the person in question gets their body back, the RoaringRampageOfRevenge is ''even worse''.

* In ''WesternAnimation/LiloAndStitch'', Stitch was designed to be a bio-terror weapon against...everyone.
%%* The Ursa from ''Film/AfterEarth''.

* In ''Film/PacificRim'', the kaiju are revealed to be genetically engineered weapons designed to conquer worlds.
* ''Film/JurassicWorld''; it's revealed that [[spoiler: the ''Indominus Rex'' was designed to be an intelligent, hyper-aggressive bioweapon for military use. Likewise, the raptor training programs was to see if they could be given orders for similar reasons.]]
* ''Animation/TheElmChantedForest'': The evil Cactus King has some of the most memorable and weird Mooks in the form of the Spinetinglers, his royal guard that is made out living, walking halberds and poleaxes.

* ''Every'' weapon of the Yuuzhan Vong, from ''Franchise/StarWarsLegends''. They use all three varieties and more.
* Creator/HarryHarrison's ''Literature/WestOfEden'' books feature the Yilanè, a race of intelligent amphibious reptiles, who rely entirely on bio-technology, including Bio-weapons.
* Shiftblades from ''The Deepgate Codex'' are souls of the dead conditioned to serve as weapons. Most remain in weapon shapes at all times, making them this trope, but one example in ''God of Clocks'' [[EquippableAlly also takes human form]].
* The two runeblades, Mournblade and Stormbringer, from ''Literature/TheElricSaga'' are soul-eating demons in the form of swords.

* The Speaking Gun from Simon R. Green's ''Literature/{{Nightside}}'' series. A conglomeration of flesh, bone, and gristle made to look like a weapon, it is a sentient creature that longs for the destruction of everything.

* Immortals in the ''Literature/CodexAlera'' are slaves raised using [[{{Slave Collar}}s discipline collars]] to ''enjoy'' pain. Nearly unstoppable, if also nearly mindless, storm troops.
** The Vord warrior forms, as is par for the course with [[VideoGame/StarCraft zerg]]/[[TabletopGame/{{Warhammer40000}} tyranid]]-style hive minds.
* In ''Literature/{{Warbreaker}}'', a sword named [=Nightblood=] is Vasher's sidekick and something of a subversion of the standard EvilWeapon. He was made with a command to destroy evil, but doesn't really get what evil is, so he mostly just does a lot of destroying. He does do his best to fulfill his purpose, and has a tendency to act almost like a murderous puppy whenever he's ignored, which makes for some surreal and slightly disturbing conversations.
* It's an open question whether True Shardblades from ''Literature/TheStormlightArchive'' count as this, given [[spoiler: that they are in fact a shapeshifted version of the EnergyBeings known as spren, which can think and talk but have no physical body and so aren't "alive" in the scientific sense of the word]]. The more common regular Shardblades probably don't count, since [[spoiler: they are spren whose minds were destroyed by the Recreance, and are much more like corpses than living creatures]].
* ''Literature/JourneyToChaos'': [=BloodDrinker=] is a sword and technically the oldest living member of the Bladi Clan. It can communicate its feelings and desires to its wielder, as well as act on its own. It also eats just the same as the other Bladi.
* The ''Literature/NemesisSaga'' ultimately reveals that Nemesis and [[{{Kaiju}} her kind]] were created to be this. [[spoiler: The Gestorumque are essentially organic HumongousMecha designed to be operated by an [[StarfishAlien Aeros]] symbiotically connected to them within a cavity in their head (though as Maigo and Endo prove, humans can fit in there too).]]
* ''Literature/DraconianSymphony'' has Drakkengard, a polymorphic sentient sword. She has the personality of an excitable guppy.
* In the backstory to Creator/GeorgeRRMartin's ''Literature/TufVoyaging'' the ancient Federal Empire's Ecological Engineering Corps used their "seedships" to introduce invasive species to enemy worlds and cause their ecosystems to collapse. Though, as Haviland Tuf, owner of the last known seedship, explained to a client in "A Beast for Norn" who wanted him to make him a monster for pit fighting, they rarely used big tough creatures with lots of natural weapons. Mostly they introduced microbes or small [[ExplosiveBreeders fast-breeding]] creatures. Still, he did have a few terrifying megafauna in stock that were used for "psychological warfare" and the like, which he sold to the pitfighting houses on that planet for exorbitant prices, throwing in small harmless-seeming critters [[spoiler: that destroyed the buyers' farmlands]] for free.
* ''Literature/SecondApocalypse'': The Inchoroi taught the [[OrganicTechnology Tekne]] to the Consult to create the "weapon races" with the intention of wiping out humanity. Weapon races include:
** [[OurGoblinsAreDifferent Sranc]], dog-sized creatures with beautiful faces who ZergRush in hordes large enough to carpet nations. They literally lust for carnage and will often mount the dead in the midst of battle.
** [[OurOgresAreDifferent Bashrag]], which are three human bodies twisted into one monstrosity.
** [[ShapeShifter Skin-spies]] have faces made up of interlocking fingers that can arrange themselves to impersonate others. Their skeletons are made of cartilage, giving them some ability to change their build to perfect the imitation.
** [[OurDragonsAreDifferent Wracu]], also called dragons, are the only race that predates the Inchoroi's arrival on Earwa. They are huge, fire-breathing monstrosities that are more than a match for any sorcerer.
* ''LightNovel/UndefeatedBahamutChronicle'' has the Abyss - monsters all named and based on various creatures in real life mythology. They can be controlled using horn flutes, but are otherwise hostile to anything (including their former masters).
* ''Literature/TheElderEmpire'': Any object invested with enough Intent can be "Awakened," given a rudimentary mind based on how it has been used in the past. This is typically only done when the Reader has a very strong understanding of the object in question, otherwise the Awakened intelligence might have very different abilities and goals than expected.

** The insectoid natives of "The Web Planet" used 'larva guns' - giant trained weevils that shot sparks from their snouts - to battle one another.

* The TabletopGame/{{Exalted}} are this, in a sense; they were made as independent weapons, simply because any form of control would utterly defeat the purpose of creating them in the first place. Less metaphorically, there exist ways to awaken the Least Gods of things, helltech involves the use of still-living demons to empower artifacts, and Craft: Genesis has done some interesting things with artificial lifeforms. Soulsteel weapons technically don't qualify, as while they do contain sapient (and eternally suffering) souls, they are usually dead.
* Creator/PalladiumBooks have some of these in their products, most notably ''{{Tabletopgame/Rifts}}'', in which the minions of the Splugorth have all kinds of bio-wizardry weapons and devices with trapped living creatures as the power supply, and sometimes the operating hardware; and ''Systems Failure'', in which the survivors of the government/military are using "Organitech" weapons and armour. Using one of the firearms they've created is described as "like holding a cockroach that shoots". Now imagine wearing the living armour...
* ''1001 Science Fiction Weapons'', for OGL, has a whole section on living organisms, beginning with bony blades, through blades which are currently alive and capable of injecting venom or pathogens, attack constructs and self-propelled living explosives, to a living grenade launcher which throws the seed-pod grenades which can shoot or burst open to release anything from short-lived carnivorous insects through toxic gas to blood infected with pathogens which quickly destroy various materials, chew through whole bodily systems within a week, or even liquify a man within minutes. A rather insidious type is a fluffy little creature, which in its most basic form emits a trill which hypnotises anyone in the area of effect, such that they can only stop and listen; not a good thing when deployed on a bus. More advanced versions will explode before the effect ends, showering the "audience" with fragments or pathogens.
* ''TabletopGame/{{Munchkin}}'''s "Singing and Dancing Sword" (a play on the Singing Sword from Myth/ArthurianLegend and the Dancing Blade from ''TabletopGame/DungeonsAndDragons'') is depicted with arms and legs (and a mouth... and a {{vaudeville}} entertainer's costume) of its own, and doesn't require any free hands to wield.

* ''VideoGame/{{Geneforge}}'' has several type 3 weapons, most notably the "batons," gun stand-ins that eat and mate. (Also, creations are type 1, but they're {{Mons}}, so no matter.)

* ''VideoGame/PokemonXAndY'' has the Honedge line, a sword that evolves into two swords, then a sword and shield, all of which wield ''themselves''. If a human tries to wield them, they eat the human's life force. The "living" status of Ghost Pokemon has always been a subject for debate, however. Amusingly, they look pretty similar to the pictured Soul Edge.

* Drudge weapons from ''VideoGame/TheConduit'' are basically this. They groan when you pick them up, use biomass as ammunition, and even breathe.
* In ''Franchise/TheElderScrolls'' series, Daedric weapons and armor are created by binding the spirits of [[OurDemonsAreDifferent lesser Daedra]] to [[FantasyMetals Ebony]] forging materials. Since Daedra possess CompleteImmortality (their physical bodies can be destroyed, but their spirits endure and reform), this means that every Daedric weapon and armor piece is still "alive". Fortunately, since each Daedra is an immortal TimeAbyss, being used as a weapon or piece of armor for a century or so (Daedric equipment tend to vanish on its own after a while) isn't really a big deal.
* ''Franchise/TheLegendOfZelda'':
** Starting in ''[[VideoGame/TheLegendOfZeldaOcarinaOfTime Ocarina of Time]]'', the series's resident LegendaryWeapon, the Master Sword, is said to have a mind of its own. In said game, the sword decided that young Link wasn't strong enough to wield it, putting him to sleep for seven years so he would be worthy.
** In ''VideoGame/TheLegendOfZeldaSkywardSword'', Fi is the spirit of the Goddess Sword, manifested as a young girl. [[spoiler:The Goddess Sword eventually becomes the aforementioned Master Sword, establishing the identity of its mind. Ghirahim, TheDragon, turns out to be one as well; he's the living embodiment of Demise's sword.]]
* The stasis weapon in ''VideoGame/StarTrekEliteForce'' is this.

* ''VideoGame/{{Warframe}}'': War, the {{BFS}} wielded by The Shadow Stalker [[spoiler:is actually a piece of the Sentient Hunhow and holds his consciousness.]]

* [[http://scp-wiki.wikidot.com/scp-127 SCP-127, The Living Gun]] from the Wiki/SCPFoundation. On the outside, it's a totally normal [=MP5K=]. Except the magazine is locked in place, and it shoots ''teeth''.

* In ''Film/TheDarkKnightReturns'', the U.S. government uses Superman as a weapon against the Soviets.

* [[http://scp-wiki.wikidot.com/scp-127 SCP-127, The Living Gun]] ('''warning, the page image is {{Squick}}y!''') from the Wiki/SCPFoundation. On the outside, it's a totally normal [=MP5K=]. Except the magazine is locked in place, and it shoots ''teeth''.

** Franchise/{{Wolverine}} was enhanced by Weapon X precisely with this purpose in mind.

* {{Deconstructed|Trope}} in ''Machinima/FreemansMind'': [[RealityEnsues a somewhat sane person who just dealt with freaky aliens of all sorts wouldn't want to touch a freaky organic weapon.]]

* The EVA units from ''Anime/{{Neon Genesis Evangelion}}''. They are [[spoiler:{{Eldritch Abomination}}s with {{restraining bolt}}s tightened on them to keep them in control. Once that armor goes off, [[TheBerserker watch out]]. To make them sync with the pilot, the people who make the [=EVAs=] have to bond a soul of their mother to the EVA, though the details aren't exactly clear, with one unit having the entirety of the soul, another just having part of a soul, and another just having a clone's soul. In any case, if the pilots come to harm, ''especially'' if it's Shinji, [[MamaBear watch out]]]].

* The Protoculture of ''Anime/{{Macross}}'' seemed fond of this sort of weapon. The most obvious example is their ServantRace, the Zentraedi, created so that the Protoculture would have super-soldiers to order around. There's also the [[Anime/{{Macross7}} Evil Series (which became the Protodeviln)]], each of which was a living superweapon with sufficient power to rend a planet in half. There's also that [[Anime/MacrossZero bird-human thing]] they left sleeping on Earth.

** {{Wolverine}} was enhanced by Weapon X precisely with this purpose in mind.

[[folder:Fanfiction]]

*** The GreenLanternRing of Alan Scott has a personality of its own, sufficient that it and Strange can confer, and it has opinions on people - it takes a liking to [[spoiler: Carol]], for instance.

* Perturabo in ''FanFic/PerturaboInRemnant'' has as a sentient Dust crystal he names Baetylus that he created when he was in a sort of trance. Baetylus is capable of feeling emotions as well as any living person, including curiosity, love and blinding rage, which are generally emoted through shifts in its color, though it can communicate to others in a limited degree via a form of telepathy that projects what it is feeling to the recipient. In regards to its capabilities, it possesses the powers of every Dust type, plus a number of other abilities that don't truly have a category. As one might expect, it is insanely powerful and completely loyal to the Primarch.

* In ''{{TabletopGame/Warhammer 40000}}'', [[HordeOfAlienLocusts Tyranid]] weapons are specially-evolved organisms fused with their wielders in a symbiotic relationship, frequently firing living ammunition. This even extends to some Tyranids, as the HiveMind is willing to expend them like ammunition, so that some organisms are bred to fight a single battle.

* The Badgersaw from ''VideoGame/{{Postal}} 3'' is kind of a cross of this type with type 1. It's a badger with a harness, so that you can hold it and have it maim your enemies.

* In ''Videogame/SwordOfTheStars'', the Liir "biological weapon" known as "the Black" that all but wiped out the Suul'ka is [[spoiler:a gigantic Liir Elder with an environmental support suit similar to the Suul'ka who has dedicated his life to eradicating them.]]

* ''Franchise/TheLegendOfZelda''

* ''Videogame/{{Warframe}}'': War, the {{BFS}} wielded by The Shadow Stalker [[spoiler:is actually a piece of the Sentient Hunhow and holds his consciousness.]]

* In ''VideoGame/TheLegendOfZeldaSkywardSword'', Fi is the spirit of the Goddess Sword, manifested as a young girl. [[spoiler: Ghirahim, TheDragon, turns out to be one as well; he's the living embodiment of Demise's sword.]]

* In ''WesternAnimation/DaveTheBarbarian'' we have Lula, the magic sword, who sometimes is ashamed to be Dave's partners. This seems to be common in universe, as we see many living weapons (and non-weapons).

** The ''Opposing Force'' expansion also introduced the [[http://half-life.wikia.com/wiki/Shock_Roach Shock Roach,]] [[http://half-life.wikia.com/wiki/Spore_Launcher the spore launcher]] ([[WordOfGod said to be]] [[http://half-life.wikia.com/wiki/Shock_Trooper#Infant_version Shock Trooper babies]]) and the [[http://half-life.wikia.com/wiki/Barnacle#Application Barnacle]] [[GrapplingHookPistol Grapple]].

* In ''Franchise/{{Halo}}'', Hunter duos (each a bonded pair of Lekgolo colonies in armor) are deployed more like equipment than infantry. ''VideoGame/{{Halo 3}}'' revealed that [[SpiderTank Scarabs]] are just really big Hunters.
* ''Franchise/KingdomHearts'' has the BigBad from [[VideoGame/KingdomHeartsI the first game]], Ansem, who fought with a monstrous LivingShadow known only as the [[GuardianEntity Guardian]]; it seems to have no will of its own and merely acts as a weapon for the character, [[spoiler:however, Kingdom Hearts III reveals the Guardian is in fact Terra's Heartless, kept bound to his body.]]

** Its opposite number Soul Calibur is one as well, albeit less prone to [[GrandTheftMe bodyjacking]].

* ''Fanfic/ChildOfTheStorm'':
** The Winter Soldier was designed to be this, a ruthless assassin and when needs be, a OneManArmy capable of singlehandedly mowing through entire squads of Aurors, defeating Captain America, the Black Widow, and Clint Barton simultaneously, killing a werewolf the size of a hummer with his bare hands, and stalemating ''Wolverine'' in a KnifeFight while carrying multiple broken ribs. There is a ''reason'' that people are terrified of him. However, a persistent streak of free will meant that he kept having to be [[MindRape brainwashed into obedience]] - and even ''that'' couldn't remove an unwillingness to hurt children if it was at all possible to avoid it (to the point where the Red Room just stopped bothering to order him on those missions as they had other assets, and HYDRA ignoring that actually triggers a temporary HeelFaceTurn).
** The Red Son was a project designed to create the Winter Soldier's SuperiorSuccessor. When it's implemented by the revived Red Room in the sequel, they enhance a PersonOfMassDestruction, rather than a latent SuperSoldier, and successfully turn them into a BlankSlate, rather than an amnesiac. The results are utterly horrifying - partly because of the sheer devastation the Red Son causes, partly because [[spoiler: it's Harry]], partly because the enhancements include - instead of a bionic arm - the Techno-Organic virus, and partly because when the person in question gets their body back, the RoaringRampageOfRevenge is ''even worse''.

* In ''Manga/FairyTail'', Franmalth, one of the Nine Gates of Tartaros, boasts that the Nine Gates are biological weapons that Zeref created to be able to [[OneManArmy take on entire armies by themselves]]. They are wholly devoted to their creator Zeref and do their best to fulfill his wishes... [[spoiler:despite never having even ''met'' him.]] Turns out, they are {{Living Weapon}}s meant to ''[[spoiler: [[DeathSeeker kill him]]]]''. The whole "devoted" bit was literally [[LaserGuidedTykeBomb wired into their creation]] so they would seek him out. [[spoiler:And only [[DragonInChief Mard Geer]] and presumably [[TheDreaded Master E.N.D.]] are aware of this little fact.]]

* In ''Disney/LiloAndStitch'', Stitch was designed to be a bio-terror weapon against...everyone.
* The Ursa from ''Film/AfterEarth''.

->'''[[ComicBook/{{Huntress}} Hunt]][[ComicBook/MsMarvel ress]]:''' I take it that something went terribly wrong at that project--?\\
'''[[ComicBook/{{Batman}} Dark]] [[ComicBook/{{Wolverine}} Claw]]:''' Actually, the program was a resounding success. It produced exactly what it set out to produce: a remorseless killing machine devoid of all human compassion. A perfect weapon. They forgot one important thing about weapons. They are usually inert objects that can't get off the table and do harm by themselves. Their mistake was in creating a weapon with an imagination.

* ÄRMs from ''Manga/{{MAR}}'' and its spin-off ''Manga/MAROmega'' can be merely magical weapons, but also sentient, humanoid or beast-like. The most notable of them is one of the two main characters, Babbo. This sassy [[https://en.wikipedia.org/wiki/Kendama toy]] with a metal head and proper gentleman's facial hair can transform into multiple different forms accordingly to his owner Ginta's [[ImaginationBasedSuperpower imagination]], including a bubble gun (yes, a gun that shoots bubbles), a [[PussInBoots cunning cat]] who has ÄRMs of his own, a [[InnocentFanserviceGirl sexy maiden]], and one [[OneWingedAngel bad mofo boss monster]].

This is the use of a living creature as a weapon. This is usually simply a subtrope of OrganicTechnology; an otherwise normal, user controlled weapon which happens to be a living thing. To qualify, 1) it must be alive when it is used[[note]]So a slingshot made from a springy Y shaped branch doesn't count, but if it was still attached to a living tree it would.[[/note]] and 2) it must be separate from the user.[[note]]So [[NaturalWeapon claws don't count]], since they're part of the creature that uses them; removing the claws from a creature and strapping them to your hand doesn't count since they're no longer a living thing, but a creature that happens to resemble a claw shaped glove that could be worn by another creature would.[[/note]]

* We have the [[http://fallout.wikia.com/wiki/K9000_cyberdog_gun K9000 cyberdog gun]] from the ''VideoGame/FalloutNewVegas'' DLC ''Old World Blues''. [[BrainInAJar It's a dog's brain stuck in a machinegun frame]]. It barks, whines, growls, and has two metal ear flaps and a little sensor/sniffer thingy that can detect enemies before you see them. Such a thing should ''really'' not be cute, [[UglyCute but it manages, somehow]].
** In addition, [[DemonicSpiders deathclaws]] are also said in the lore to be chameleons genetically engineered and hybridized with other animal stock to replace American troops in the war with China; after the Great War, they have become the intelligent, vicious predators they are in the games. This is considered to be BroadStrokesCanon, though, as this backstory is not explained in the main games.

* ''VideoGame/HalfLife'' has the Hivehand, basically a living alien beehive which shoots a constantly replenishing supply of [[BeeBeeGun bee-like aliens]]. There's also the Snarks. If you can get some from their nest, you can sic them on enemies, where they'll pester them rather effectively until they either get smashed or blow themselves up.
** The ''[[VideoGame/HalfLifeOpposingForce Opposing Force]]'' expansion also introduced the [[http://half-life.wikia.com/wiki/Shock_Roach Shock Roach,]] [[http://half-life.wikia.com/wiki/Spore_Launcher the spore launcher]] ([[WordOfGod said to be]] [[http://half-life.wikia.com/wiki/Shock_Trooper#Infant_version Shock Trooper babies]]) and the [[http://half-life.wikia.com/wiki/Barnacle#Application Barnacle]] [[GrapplingHookPistol Grapple]].

* Four out of the six weapons in ''VideoGame/Prey2006''. One will even look around if [[IdleAnimation bored]]
* ''VideoGame/ShadowsOfTheDamned'' has Garcia's sidekick Johnson, a demonic skull-torch who can transform into various guns. His default form functions as both a torch and Garcia's melee weapon.

* ''VideoGame/WorldOfWarcraft'' features a number of weapons that are alive. Such as the Dark Edge of Insanity, an axe that drops from an [[EldritchAbomination Old God]]. The axe itself appears to be covered with black reptilian skin, and is adorned by a huge yellow eye, that BLINKS and turns in its socket. Another example is Terestrian's Stranglestaff, the upper end of which consists of a rather disgusting octopus-like creature with squirming tentacles and a beak. And Zhar'doom, Greatstaff of the Devourer, is actually a Zergling/Felhunter-like creature stretched to the form of a staff. The head of the beast is the head of the staff, which clacks its jaws littered with very sharp teeth, and lashes forward with its tentacles.
** The Mogu created the lizard-like Saurok as a living weapon to police and control their empire. The Saurok were too wild to be controlled in such a manner and eventually rebelled against the Mogu.

* ''VideoGame/{{Geneforge}}'' has several type 3 weapons, most notably the "batons," gun stand-ins that eat and mate. (Also, creations are type 1, but they're {{Mons}}, so no matter.)
* In ''VideoGame/GranblueFantasy'', Primal Beasts were created and/or altered to be weapons of the Astrals during the War.

* The Badgersaw from ''VideoGame/{{Postal}} 3'' is kind of a cross of this type with type 1. It's a badger with a harness, so that you can hold it and have it maim your enemies.
* We have the [[http://fallout.wikia.com/wiki/K9000_cyberdog_gun K9000 cyberdog gun]] from the ''VideoGame/FalloutNewVegas'' DLC ''Old World Blues''. [[BrainInAJar It's a dog's brain stuck in a machinegun frame]]. It barks, whines, growls, and has two metal ear flaps and a little sensor/sniffer thingy that can detect enemies before you see them. Such a thing should ''really'' not be cute, [[UglyCute but it manages, somehow]].
** In addition, [[DemonicSpiders deathclaws]] are also said in the lore to be chameleons genetically engineered and hybridized with other animal stock to replace American troops in the war with China; after the Great War, they have become the intelligent, vicious predators they are in the games. This is considered to be BroadStrokesCanon, though, as this backstory is not explained in the main games.
* In ''VideoGame/MetroidPrimeHunters'', Kanden's Volt Driver was stated in a Scan Log as being a LivingWeapon.

* One of the calling cards of ''VideoGame/OddworldStrangersWrath'' was its spin on the idea of "live ammunition". To explain, Stranger uses tiny living creatures as ammo for his crossbow (each with various effects).

* ''Franchise/KingdomHearts'' has the BigBad from [[VideoGame/KingdomHeartsI the first game]], Ansem, who fought with a monstrous LivingShadow known only as the [[GuardianEntity Guardian]]; it seems to have no will of its own and merely acts as a weapon for the character.
* Drudge weapons from ''VideoGame/TheConduit'' are basically this. They groan when you pick them up, use biomass as ammunition, and even breathe.

* ''VideoGame/ShadowsOfTheDamned'' has Garcia's sidekick Johnson, a demonic skull-torch who can transform into various guns. His default form functions as both a torch and Garcia's melee weapon.
* There's a reason that the mutant monsters in ''Franchise/ResidentEvil'' are called [[FunWithAcronyms B.O.Ws]], or "Bio-Organic Weapons". The whole point behind Umbrella, and later organisations, is to engineer living weapons.
* ''VideoGame/LeagueOfLegends'' has a few:
** Zac is an [[BlobMonster amorphous ooze monster]] [[ToxicWasteCanDoAnything born of toxic waste]] whose title is "The Secret Weapon", but he's actually a pretty NiceGuy, and one of the most genuinely heroic champions to come out of [[WretchedHive Zaun]].
** The Darkin, originally a group of [[PhysicalGod Ascended]] who protected the world from The Void, [[FallenHero but became such a grave danger themselves]] that [[SealedEvilInACan they were sealed into cursed, semi-organic-looking weapons]]. [[AndIMustScream They were hidden away for ages]], but some have unfortunately come back, and not only are they not happy, [[TheCorruption they've also learned how to]] [[GrandTheftMe hijack the body of whoever tries to wield them]]. Those known are:
*** Varus, imprisoned in [[EnergyBow a bow]]. Varus currently occupies a body [[SharingABody shared by]] ''[[SharingABody three]]'' [[SharingABody minds]]: himself, and two lovers named Valmar and Kai, [[EnemyWithin who are doing everything in their power to restrain him]].
*** Rhaast, imprisoned in [[SinisterScythe a scythe]]. Currently possessed by and locked in a duel with [[{{Ninja}} Kayn]], [[CastingAShadow The Shadow Reaper]], with Kayn seeking to purge Rhaast from the weapon and Rhaast attempting to consume Kayn's body.
*** Aatrox, imprisoned in [[CoolSword a sword]]. He has successfully usurped a host body, but [[FallenHero the betrayal]] and [[AndIMustScream endless imprisonment]] he's suffered has left him so [[AxCrazy irreparably furious]] that [[OmnicidalManiac he intends to exact apocalyptic levels]] [[SuicidalCosmicTemperTantrum of vengeance on the universe]].
* In ''Videogame/SwordOfTheStars'', the Liir "biological weapon" known as "the Black" that all but wiped out the Suul'ka is [[spoiler:a gigantic Liir Elder with an environmental support suit similar to the Suul'ka who has dedicated his life to eradicating them.]]
* ''VideoGame/PokemonXAndY'' has the Honedge line, a sword that evolves into two swords, then a sword and shield, all of which wield ''themselves''. If a human tries to wield them, they eat the human's life force. The "living" status of Ghost Pokemon has always been a subject for debate, however. Amusingly, they look pretty similar to the pictured Soul Edge.
* The Blade of Ahrah from ''VideoGame/DustAnElysianTail''.
* The Sonic Eruptor from ''VideoGame/RatchetAndClankFutureACrackInTime'' is essentially a frog-like creature attached to a holder. When the gun is fired, the creature unleashes a mating call loud enough to create a devastating shock wave.
* In ''VideoGame/{{Destiny}}'', the Dreadfang (a sword) and Stolen Will (a shotgun) are ''Taken weapons'', that is, weapons that were ''Taken''. Given that only biological things can be taken (even the Vex are technically bacteria in [[PoweredArmor mechsuits]]), it [[BodyHorror gives]] [[NightmareFuel pause]]. They also double as [[EvilWeapon evil weapons]], or at least until you get your hands on them.

* ''VideoGame/{{Sundered}}'' has the Shining Trapezohedron, a sentient, talking crystal that serves as the protagonist’s primary weapon. It’s a MorphWeapon that forms blades, fists, and other appendages out of tendrils of dark energy, which coil around whichever limb the protagonist is currently swinging at an enemy. Beyond that, it has the power to “corrupt” the various gadgets the protagonist picks up throughout her quest, making them more powerful by turning her into a monster whenever she uses them. [[spoiler:Unsurprisingly, it turns out to be an EvilWeapon and a fragment of ''[[EldritchAbomination Nyarlathotep]]''.]]
* In ''VideoGame/FinalFantasyXIV'', you ''accidentally'' create this with the Anima Weapon line. When making an Anima Weapon, the weapon for that class is infused with so much aether (the building blocks of life in that universe), that a new life takes. As you make the weapon stronger and stronger, it becomes more and more sentient and, at the end, comes to realize that it might actually be a Primal of sorts. However, it doesn't mind and wants to help protect you no matter what. And there's a major possibility that it'll just keep getting stronger.
