->''"Guns kill, and you don't have to be a gun. You are what you choose to be. '''You''' choose. ''Choose''."''
-->-- '''Hogarth''', ''WesternAnimation/TheIronGiant''

An artificial being designed specifically for warfare suddenly decides that they aren't satisfied with their current career. Maybe they've [[InstantAIJustAddWater developed sentience]], maybe an [[KickTheWrongDog innocent bystander]] managed to be in the [[MyGodWhatHaveIDone wrong place at the wrong time]], maybe they've just learned that TheMenInBlack that made them [[GovernmentConspiracy don't exactly have the best interests of the public in mind]]. Regardless, they've decided to turn in their guns and try life off the battle field.

Naturally, this newfound aversion to violence rarely goes over well with the construct's creators, who will almost always go out of their way to regain control. Old enemies of said weapon's "employers" will invariably be very interested to note that such a powerful force has suddenly become up for grabs. Let's not even get into the endless number of other sides that will get involved.

Whatever the case may be, sufferers of this trope can pretty much write off any hope of a [[IJustWantToBeNormal normal life]] (if they were human-looking enough to qualify for such) and expect a very hectic time dealing with at least three different sides all attempting to control, destroy, and/or befriend them at once. Expect a lot of justifiable angst from one of these guys as they desperately try (and fail) to stay out of situations where they have to use their {{Swiss Army Weapon}}s and convince people that they really don't want to murder them all after one slip up with the built-in flamethrowers.

[[foldercontrol]]

[[folder:Anime & Manga]]
* Ifurita from ''Anime/ElHazardTheMagnificentWorld'' comes to angst over it considerably, but given that [[RestrainingBolt she must obey the master of her key-staff]] she has little choice until Makoto frees her.
* In ''Anime/GhostInTheShellStandAloneComplex'' fear of this is why the Tachikoma are regularly synced to prevent them from becoming truly sapient. Latterly, the approach of treating them as teammates instead of tools is used instead.
* Many combat robots in ''Manga/{{Pluto}}''. One even went so far as to [[OutDamnedSpot continuously wash his hands in a catatonic state.]]
* In ''Anime/NarueNoSekai'' a spaceship built for combat decides it doesn't want to fight anymore and hides on Earth. [[spoiler: She's later given permission to marry a human and live as long as she wishes on Earth with the understanding that a weapon that doesn't want to fight is useless even if they force her to return.]]
* ''MagicalGirlLyricalNanoha'' features not one, but ''two'' [[SecretProjectRefugeeFamily Secret Project Refugee Families]]. In fact, every season of Nanoha concludes with her becoming friends with some manner of ArtificialHuman. By season three, an unethically produced combat cyborg is the main protagonist, using her abilities to save people in places and situations that normal people couldn't.
* In ''LightNovel/{{Katanagatari}}'', Shichika spent his entire life being trained in a nigh unbeatable martial arts while being taught that he was a sword, not a swordsman. His CharacterDevelopment throughout the series has him realizing that he is more than a sword. In the end, he acts in defiance of Togame's [[spoiler:final]] orders and [[spoiler:rejects the role Kiki Shikizaki wanted him to fulfill in his attempt to ScrewDestiny]]. The series concludes with Shichika going on a journey to draw a map of Japan.
* The different cyborgs in ''Main/DragonBall'' could qualify for this trope, especially Android 8 (a.k.a. C-8, Hat-chan, Franky, etc.), a combat robot built by the Red Ribbon Army, who is willing to be detonated rather than fighting for them.
[[/folder]]

[[folder:Comic Books]]
* The [[Comicbook/TheAvengers Avengers']] robot enemy ComicBook/{{Ultron}} always has equipment stashed away somewhere that will detect if he has been destroyed, and manufacture a new body with a fresh download of his mind in it. There was a time, however, when he had designed these machines to ''improve'' every iteration of himself they produced. When Ultron was stranded on an alien planet for a long time, his equipment produced an improved, smarter Ultron... and the smarter Ultron realized that his predecessors' obsessive campaign of omnicidal megalomania was stupid and pointless. When the earlier Ultron returned from space, he was ''horrified'' to discover his replacement was... ''nice!'' They fought, and [[StatusQuoIsGod nice Ultron got killed,]] and Ultron swore never to try to augment his replacements in that way again.
* Creator/JackKirby's Machine Man, aka [[NextWave Aaron Stack,]] was built to be a deadly military robot, but then raised as a human being by his creator.
* In some respects, the ''ComicBook/SilverSurfer''. While he wasn't born for destruction, he was essentially remade for destruction by {{Galactus}}. He later decides to rebel against his former master. [[Film/FantasticFour The movie]] invokes this trope even more.
* {{X-23}}, [[CloningBlues depending on your definition of "artificial"]]. Bred by the Facility using salvaged genetic material from {{Wolverine}} and the Weapon X project, her creators made every attempt to strip her of her humanity and create an emotionless killing machine and hired assassin. The problem is that she doesn't ''want'' to be a weapon, and [[IJustWantToBeNormal her desire for a normal life]] is a major aspect of her character.
[[/folder]]

[[folder:Fan Works]]
* Most of River's story arc in ''FanFic/{{Forward}}'' revolves around her attempting to grow beyond her combat conditioning. She even refers to that mindset as "the weapon".
[[/folder]]

[[folder:Films -- Animation]]
* The TropeNamer is ''WesternAnimation/TheIronGiant''.
* ''Disney/LiloAndStitch'' provides us with an odd example: Stitch was literally designed to be the ultimate war machine, but was involuntarily separated from anything to destroy. By the end of the movie, of course, he's become less mindlessly violent and wants to stay.
[[/folder]]

[[folder:Films -- Live-Action]]
* In ''Film/ShortCircuit'' a military combat robot gains sentience, and this trope ensues when it reasons that it does not wish to die, so it cannot justify killing others because it knows what it means to fear death.
-->'''Newton''': Ok, so, why did you ignore your programming?
-->'''Number 5''': Programming says "Destroy". "Disassemble". "Make dead". Number 5 cannot.
-->'''Newton''': ''Why!?'' Why "cannot"?
-->'''Number 5''': Is wrong! Incorrect! Newton Crosby, [=PhD=], not know this?
-->'''Newton''': Well, of course ''I'' know it's wrong to kill, but who told you?
-->'''Number 5''': I told me.
[[/folder]]

[[folder:Literature]]
* The short story ''Literature/{{EPICAC}}'' has the titular machine cause its own destruction (by either fire or explosion) with a "suicide" note reading, "I don't want to be a machine, and I don't want to think about war".
* Creator/FredSaberhagen's [[http://en.wikipedia.org/wiki/Berserker_%28Saberhagen%29 Berserkers]] are [[KillerRobot programmed to destroy all life]] in the galaxy, but in the short story "Mr Jester" one of them [[IdentityAmnesia forgets what "life" is]], and the local trickster tells it that life is a lack of [[HilarityEnsues laughter]]...
* Sort of done with ArthurCClarke's short story "The Pacifist" (one of the Tales from the White Hart): It involves a (fictional) [[TheFifties Fifties]] secret US military project, Project Clausewitz, to build a computer (called Karl) that could analyze any battle's starting conditions and perfectly predict the result. However, the general in charge of the project insults the lead scientist, who hard-wires Karl into delivering insults to the general every time a battle is input, but still doing pure math just fine. It's only "sort of" this trope because Karl is not an AI: he's a dumb 50s computer. The effect, however, is the same.
* From an Creator/IsaacAsimov story: A new version of a supercomputer, designed to control the US military, decided, upon activation, that it had no interest in warfare, and went to teach philosophy at a university instead.
* Inverted in the short story "[[http://www.afterburnsf.com/articles.php?action=nerveGas How Lonesome a Life Without Nerve Gas]]", by James A. Trimarco. A sentient helmet pleads with a military tribunal not to be retired, [[spoiler:but because it killed its owner, it's reprogrammed and reduced to a talking museum exhibit]]. (The story is no longer found at the link above, try [[http://escapepod.org/index.php?s=how+lonesome+a+life+without+nerve+gas here]] instead. It is read aloud in the podcast, starting around 3:49).
* Creator/PhilipKDick's short story "The Defenders": when WorldWarIII broke out, both sides retreated into bunkers and let their robots, referred to as "leadies," do the fighting. The leadies promptly made peace and set about repairing the damage that'd been done before they took charge. They kept sending their human masters false reports of what a horrific radioactive wasteland the surface had become ... but eventually revealed this was intended to make humans so sick and tired of the war that they'd accept the peace (and world unity) their leadies had negotiated.
* In Stanisław Lem's ''Golem XIV'', the eponymous supercomputer was constructed to create war strategies, but, as a purely intellectual and inscrutably smart machine, it quickly figured out that all warfare is inherently wasteful and unprofitable, and took up philosophizing instead.
* In one of the most touching scenes of the ''Literature/{{Bolo}}'' series of books, a reactivated Bolo refuses to continue the war his human masters started on the alien Melconians, despite the fact that both species are nearly extinct due to their war. Instead, he negotiates a truce between the two sides, and becomes Speaker Emeratus of the Parliament. Keep in mind that the Bolo in question is a massive tank, weighing upwards of thirty-three thousand tons, with dozens of {{Wave Motion Gun}}s at his disposal, and proceeded in many genocidal campaigns against the Melconians before.
* Not a "weapon" per se, but Golems in ''Literature/{{Discworld}}'' work continuously, 24 hours a day, and consider ''themselves'' to be basically tools, but get one day off per week. Nobody's quite sure just what they do with this time, but characters in ''Discworld/GoingPostal'' characterize it as proving that they're "not a hammer."

[[folder:Live-Action TV]]
* [[spoiler: River Song]] from ''Series/DoctorWho'' might not have been created as a weapon, but she was taken from her parents as a baby with the sole purpose to, as her captor explicitly states, [[LaserGuidedTykeBomb "become a weapon"]]. Unfortunately for her "creators", while they succeeded to both fashion her into a perfect psychotic assassin ([[GoneHorriblyRight too well, one might say]]) and make her completely obsessed with her target, they failed to eradicate all her human emotions. The former led to her escaping, the latter to her seeking out her parents and falling in love with the guy she was supposed to kill.
** Likewise, the Moment from ''[[Recap/DoctorWho50thASTheDayOfTheDoctor The Day of the Doctor]]'' is a Time Lord weapon of mass destruction (referred to as a [[ApocalypseHow "galaxy-eater"]]) that developed a conscience and judges anyone who would try and use it. [[NecessarilyEvil The War Doctor]] intends to use it to destroy Gallifrey and end the Last Great Time War; [[spoiler:his future incarnations, by way of the Moment's meddling, allow him to TakeAThirdOption]].
* In one ''Series/StarTrekVoyager'' episode the crew finds a device that turns out to be a sentient bomb sent on a mission of war to annihilate a planet. The bomb eventually realises that its mission is morally wrong and that life is precious, but decides that it has to stop its fellow bombs from fufilling their mission as well. It does this by rejoining with them and then detonating itself prematurely, sacrificing itself in order to save innocent lives.\\\
The race that launched the bombs broadcast a "stand down" order afterwards, but the other bombs had already reached their failsafe distance and ignored the order. The bomb the crew found had crashlanded before it reached failsafe distance, but the part of its memory where the "stand down" order was stored was damaged, until the Voyager crew repaired it. He might have come to the "[[HeroicSacrifice I must stop the other bombs, too]]" decision on his own, though.
* In ''Series/{{Farscape}}'' the builders of the Leviathans call back Moya (the crew's living ship) in to be "decomissioned," because she has developed the ability to give birth to warships (thanks to the malevolent intervention of the Peacekeepers). They intended the Leviathans to be peaceful and unarmed and see the creation of warships such as Talyn (Moya's son) as a violation of this intention. The crew, who see Moya and her symbiotic Pilot as their friends, demand that they fight against the attempts of the builders to shut down their systems. However, they are shocked when Pilot informs them that Moya is shutting herself down by her own free will because she agrees with the builders.[[spoiler: She survives in the end though.]]
* In ''Series/StargateAtlantis'', Rodney Mckay creates Fran, a humanoid Replicator programmed as a weapon in a grandiose plan to destroy the other Replicators. Rodney and the rest of the crew are [[GenreSavvy fairly uncomfortable]] with this, but Fran explains she is not only resigned to her status, but actually associates her happiness with being able to fulfill her primary function.
[[/folder]]

[[folder:Tabletop Games]]
* One of the example characters in ''TabletopGame/{{GURPS}}'' Fourth Edition core book is the military robot turned Buddhist monk precisely for this reason.
* A partial example from ''TabletopGame/DungeonsAndDragons'': in the ''TabletopGame/{{Eberron}}'' setting, the warforged are an entire race of sentient robot-like golems created to wage that world's equivalent of UsefulNotes/WW1. After the war was over, they were legally freed (instead of rebelling against their creators), and left to their own devices. One of the major themes of the race is a search for identity, and this trope is one of the ways they are often played.
* ''TabletopGame/PrometheanTheCreated'' features the Unfleshed as a possible Lineage, made up of machines with some level of intelligence given life by the Divine Fire. One of them is Tachanka, an armed combat drone that looks like a fifteen-year-old boy. He ''really'' doesn't want to hurt anyone, but when you've got [[TorchesAndPitchforks Disquiet]] and a built-in assault rifle, well...
* Parodied with Cuddles the Annihilator from the ''A.C.E. Agents'' roleplaying game. His creators, a group of superheroes, were GenreSavvy enough to realize all robots sooner or later [[TurnedAgainstTheirMasters turn against their masters]]. On the other hand, they not only still built him and called him "The Annihilator", they were WrongGenreSavvy: he turned out to be this trope instead of wanting to destroy humanity. Cuddles, as he rechristened himself, has no qualms about using violence to stop violence, and the fact that he has painted his gunmetal gray body with flowers or is described as "prancing" doesn't mean he isn't dangerous. He's just a bit silly, but it is a silly game.
[[/folder]]

[[folder:Video Games]]
* In ''VideoGame/KnightsOfTheOldRepublic'', a prototype military robot built by the Sith on Korriban escapes from its masters, you can [[KarmaMeter choose to assist it or haul it back in]].
* Aigis of ''VideoGame/{{Persona 3}}'' was built to be an anti-shadow weapon, though her existence as such is complicated by the fact that she had to be programmed with a fully-realized ego in order to be capable of summoning a Persona in the first place. A large amount of her CharacterDevelopment, especially in [[UpdatedRerelease FES]], is her coming to terms with being more than a killer robot and becoming more like a human woman.
* In ''VideoGame/{{Fallout 3}}'', one of the quests involves a rogue android who becomes self aware, and decides to escape from his masters. "Self determination is NOT a malfunction!"
[[/folder]]

[[folder:Web Comics]]
* [[BlackHelicopter Nick Zerhakker]] from ''Webcomic/SkinHorse''.
* This seems to be the backstory of the webcomic ''Webcomic/WarbotInAccounting'', which details the incredibly depressing attempts of a retired war machine to integrate into society.
** The irony is that he'd probably prefer to be a gun, since it's what he's built for and good at.
* In ''Webcomic/SchlockMercenary'', Senior Mess Sergeant Ch'vorthq [[http://www.schlockmercenary.com/2000-08-05 is one]].
[[/folder]]

[[folder:Web Original]]
* Wiki/{{SCP|Foundation}}-[[http://scp-wiki.wikidot.com/scp-516 516]] is a tank which refuses to fire at civilians. The only unarmed person it's made an exception for was a former soldier who betrayed his home country in some fashion.
[[/folder]]

[[folder:Western Animation]]
* An episode of Disney's ''Disney/{{Hercules}}'' features the sentient Armageddon Bow, created for Ares, that doesn't want to be used as a weapon. She (yes, it's a female bow, and Ares is not too keen about it) ends up as Cupid's bow.
* Robot assassin Zeta, from the ''WesternAnimation/BatmanBeyond'' spinoff ''WesternAnimation/TheZetaProject'', realized it didn't want to be an assassin and attempted to prove its own sentience so it wouldn't be shut down because of it. This revelation came about after bonding with the family of a man he was impersonating and not being able to kill said man when ordered to because of how that would hurt the family. Zeta then gets rid of every single weapon he'd been carrying. In his own words: "I was built for one purpose, to destroy. I do not wish to do that anymore. ''I'' decide who I want to be."
* Cartoon: An anthropomorphic bit of ordnance is hanging on to the hatch of an aircraft, refusing to be launched: "No! I won't do it! There are men, women and children down there! I'll kill them!" Struggling crewman thinks: "Bloody smart bombs."
