* ''Film/ForbiddenPlanet'': Despite what the poster would have you believe, this is also averted: Robbie is pretty tame to start with and has a MoralityChip that makes it ''impossible'' for him to [[ThreeLawsCompliant harm]] any other "rational being".
%%* The brainwashed people in ''Film/TheNakedGun'':
%%--> ''Reggie Jackson:''' Must... kill... Queen.

* Averted in ''Film/TheDayTheEarthStoodStill1951'', where the peace keeper robot is entirely silent when on murderous rampages. This was extremely unusual for the time period.

* ''VideoGame/{{Fallout}}'': Robots in the Fallout universe seem to default to "kill everything in sight" should their coding go wrong in any way. There are numerous robots in the wasteland that have gone haywire and will attack anyone unfortunate enough to cross their path (not so bad with a humble [[TinCanRobot Protectron]], but extremely dangerous Sentry Bots, Mister Gutsies, and Assaultrons also exist). You can also [[InvokedTrope invoke]] this trope by destroying a robot's [[MoralityChip combat inhibitor]], making them attack their own allies as well as you.

* ''ComicBook/XMen'': The 'pet' [[GiantRobot Sentinel]] Rover in "Here Comes Tomorrow" had a one word vocabulary. That word was "DESTROY."

* In the ''Franchise/XMen'' franchise - ''the Sentinels''.

* ''ComicBook/AvengersAcademy'': Juston's RobotBuddy / HumongousMecha Sentinel regularly says "Destroy All Mutants!", despite never actually making any efforts towards that goal.
* In the short-lived DC comic ''ComicBook/AtariForce'', the friendly toy robot, Bob, who could only say his name cheerfully, went evil after one too many flushes down the toilet. It could still say nothing more than "Bob", but it said it in a much more menacing voice to the point it was obvious that if its vocabulary were bigger, it would've been saying the trope title verbatim.

* In the ComicBook/MickeyMouseComicUniverse story "Darkenblot 2.0" Robopolis' new power source has the side effect of making all robots malfunction in a way they damage everything in their vicinity and cannot recognize humans anymore, thus bypassing the fact they're factory-hardcoded to be ThreeLawsCompliant [[GenreSavvy due the people of Robopolis knowing exactly what kind of danger depending on robots implies]]. Thankfully, [[ProperlyParanoid local law also mandates the robots to be hardcoded to deactivate on the spot if anyone says a certain word]], and it takes about a minute before the mayor gets on tv and starts revealing the passwords (different for every model).
* ''ComicBook/TheTransformersMarvel''; The Guardian Units have a distressing tendency to revert to this at the drop of a hat, and happen to be incredibly well-built and well-armed. Even worse, they seem to be the exclusive property of the Autobots.
* The ''ComicBook/UltimateMarvel'' incarnation of Galactus, a swarm of killer robots called Gah Lak Tus, is dedicated to consuming and wiping out all organic life which it finds disgusting. The swarm repeatedly states its mission: "Consume". This changes when they meet 616-Galactus after he ends up in the Ultimate universe thanks to a tear in the fabric of the multiverse. They attempt to consume him at first, repeating "Consume". Then they switch to [[FusionDance "Merge"]]. Finally, "Serve".

* ''VideoGame/SonicTheHedgehog'': E-123 Omega is a textbook TurnedAgainstTheirMasters variety who is ''really'' pissed off about Eggman shutting him down and leaving him. And he's [[BloodKnight very entertaining]] in battle. ANNIHILATION! CHARGE! FIRE!

* ''Series/GetSmart''. Hymie the android was programmed by KAOS to kill and ''Theatre/HelloDolly'' (sorry, ''Theatre/{{Mame}}''...I mean maim!), but that was before CONTROL reprogrammed him for goodness and niceness.

* ''Series/LostInSpace'': This line is often mis-attributed to The Robot who does use the term "Destroy" several times in the pilot during his rampage. It's Killer Android IDAK Alpha 12 who says this in the episode titled, "Revolt of the Androids." Despite its use in only one episode, it became a more famous line than "Destroy" and was thus attributed to the main character robot.
** This becomes an AscendedMeme in TheMovie; Will has the Robot deliver the line (to scare his dad) in the scene where he shows that he's gained control over it. The [[Film/LostInSpace movie]] soundtrack even has a {{Sampling}} track of the Robot saying "Destroy."
* ''Series/MysteryScienceTheater3000'''s Mike Nelson built a robot in episode #602, following the lead of ex-host Joel Hodgson, who built fellow snarkers Crow and Tom Servo. However, Mike's robot seemed only able to shout "DESTROY.. DESTROY.. DESTROY..". After he shuts it down, Crow and Tom force Mike to promise not to try and build another.
* ''Series/RedDwarf'': The Hudzen 10 droids were intended to replace the Series of Mechanoids which [[RobotMaid Kryten]] was part of. However, the one sent out to replace Kryten had seen a deterioration in his sanity chip. The result is that when the crew refused to turn Kryten off, he attempted to kill them all.
* ''Series/StarTrekTheOriginalSeries'': In "The Changeling", when {{mind meld}}ing with Nomad, Spock perceives the KillerRobot's PrimeDirective as a result of CorruptedData, chanting "[[OmnicidalManiac Sterilize imperfections]]... sterilize... sterilize!" until Captain Kirk shouts at Nomad to break off the connection.
* ''Series/StarTrekVoyager''. Satan's Robot from the ''[[ShowWithinAShow The Adventures of Captain Proton!]]'' holoprogram enjoys saying "SUR-REN-DER!" as it clanks menacingly towards people. Seven of Nine was unfazed, simply turning it off and asking Tom, "Can I go now?"
* ''Series/TheTwilightZone1959'': In "[[Recap/TheTwilightZoneS4E103InHisImage In His Image]]", the android Alan Talbot frequently experiences uncontrollable urges to kill. He attacks his creator Walter Ryder, Jr. with a scissors and pushes an extremely persistent evangelist under a subway train.

* The [[OrganicTechnology organic robots]] known as [[http://www.bogleech.com/mortasheen/z-mangler.htm Manglers]] do this in ''WebOriginal/{{Mortasheen}}''.

'''RobotBuddy [[AllThereInTheManual Instruction Manual]]'''

Congratulations kid! You've got your first RobotBuddy, RidiculouslyHumanRobot, or DoAnythingRobot! But before you start playing with it and [[ABoyAndHisX going on magical adventures together]], there's a few things you need to know:

* ''WesternAnimation/{{Futurama}}''

'''R.E.C.R.:''' I must destroy all enemies! Because all enemies are MY enemies!

** Mr. Burns orders robot workers, and the box says "100% Loyal." The next scene is Burns and Smithers being chased by the robots, who are droning "Crush, kill, destroy!" over and over.

** In "Itchy & Scratchy Land", the cat and mouse robots have a protocol that ensures that they only [[RoadRunnerVsCoyote attack each other]]; their HUD commands them to "KILL" their opposite number. Inevitably, they malfunction, and the "KILL" command is demanded of human targets.

** "MAGIC.MOV": CRUSH! KILL! DESTROY! [-[[{{Catchphrase}} SWAG]].-] (Done by the [[RobotMe RD]]-[[AdvancedTech2000 5000]]) It even got its way to [=BronyCon=].

* ''ComicBook/AvengersAcademy'': Juston's RobotBuddy / HumongousMecha Sentinel regularly says "Destroy All Mutants!", despite never actually making any efforts towards that goal.

** [[https://www.youtube.com/watch?v=Ju9GQ4Tmz74 Now in]] StupidStatementDanceMix form by General Mumble. The lyrics consist mostly of the RD-5000's voice clips and Twilight's hilariously short-sighted suggestion.

** This becomes an AscendedMeme in TheMovie; Will has the Robot deliver the line (to scare his dad) in the scene where he shows that he's gained control over it. The [[Film/LostInSpace movie]] soundtrack even has a StupidStatementDanceMix of the Robot saying "Destroy."

* ''WesternAnimation/SpongeBobSquarepants'': Squidward gets a security system for his house to keep SpongeBob and Patrick out of his hair. However, when it perceives no threat from the duo, he gets angry and begins to knock on it in order to get it to work. This ends up making it perceiving ''him'' as a threat as the security system takes control of Squidward's house and begins attacking the city.

* Galactus from the ''ComicBook/UltimateGalactusTrilogy'', a swarm of killer robots called Gah Lak Tus, is dedicated to consuming and wiping out all organic life which it finds disgusting. The swarm repeatedly states its mission: "Consume". This changes when they meet 616 Galactus after he ends up in the Ultimate verse thanks to a tear in the fabric of the multiverse. They attempt to consume him at first, repeating "Consume". Then they switch to [[FusionDance "Merge".]] Finally, "Serve".

* ''LightNovel/TrinityBlood'': [[DeceptivelyHumanRobots Deceptively Human Robot]] Tres Iqus engages in "Genocide Mode" when using his ImplacableMan GunKata to kill mooks.
* Arguably, in ''Anime/TheAnimatrix'', the robot that signs the unconditional surrender treaty at the UN, when it calmly says "Hand over your flesh and a new world awaits you. We demand it." [[spoiler:Right before it self-destructs in an atomic blast, killing everyone at the UN]]

* The ComicBook/UltimateMarvel incarnation of ComicBook/{{Galactus}}, a swarm of killer robots called Gah Lak Tus, is dedicated to consuming and wiping out all organic life which it finds disgusting. The swarm repeatedly states its mission: "Consume". This changes when they meet 616 Galactus after he ends up in the Ultimate verse thanks to a tear in the fabric of the multiverse.

** The [[BonusBoss Automated Dreadnought]] Leviathan is a fully autonomous warship still fulfilling it's last order from a fallen star nation despite the loss of it's organic crew, and has been fulfilling said order for the lasthundreds of thousands of years: defending a strategically important star system from any and all hostile incursion.

* ''VideoGame/DigimonWorldNext0rder:'' [=RustTyrannomon=] gets stuck on its "rampage" function. Not a good thing when you're a robotic T-Rex shaped tank with a rail gun on your back. Fortunately, a good-old fashion pummeling defrags it.

Is generally considered to be overused nowadays, so you'll rarely find it used straight in contemporary live-action works, but [[DeadHorseTrope it still pops up in cartoons for camp value.]] If it's the focus of an episode, it's a GlitchEpisode (and possibly an UnexpectedlyDarkEpisode if the series doesn't usually involve putting characters in mortal peril). Compare ''HolodeckMalfunction'', which often involves whatever is preventing the Holodeck from killing its participants or escaping shuts down, but continues running.

* Contingency [[TrueFinalBoss end game Crisis]] in ''VideoGame/{{Stellaris}}''

* ''ComicStrip/TheFarSide'' has one strip in which a boy tries to present his class project for metal shop to his inattentive teacher. The project is a room-high Unnecessarily creepy robot equipped with [[TankTreadMecha tank treads]], PowerPincers, spiked shoulders and a serrated maw. ''The [=PreHistory=] of The Far Side'' expands on this picture with a short story explaining how, under time pressure, the robot's design deviated horribly from its original purpose "to do peaceful functions and serve mankind":
