18[[ExactlyWhatItSaysOnTheTin A psychopath who's also a robot]]. Compare AIIsACrapshoot where the robot isn't intended to be evil. Expect it to be a MurderousMalfunctioningMachine. If they happen to be a good guy (or at least working as good guys' RobotBuddy), they'll probably be a SociopathicHero. Needless to say, this AI unambiguously possesses sapience as much as organic beings.

29[[folder:Anime & Manga]]
30%%* Red Destiny in ''Anime/TheBigO.''
31* Machinedramon from ''Anime/DigimonAdventure''. Despite his CreepyMonotone voice, he's a psychopathic monster who takes sadistic pleasure in destroying everything in his path.
32* The Androids from ''Manga/DragonBall'' and ''Anime/DragonBallZ'' were intended by their creator(s) to be these, but [[AIIsACrapshoot almost all of them ended up turning]] ''[[HeelFaceTurn good]]'', the main exceptions being the ones in Future Trunks's timeline / dimension. And those Androids are actually ''humans'' altered by Doctor Gero.
33* ''Manga/{{Pluto}}'':
34** Brau 1859, the first and only robot to ever kill a human because he wanted to. His personality and role is an {{expy}} of Hannibal Lecter, to give you a sense of what we're talking about. Despite being badly damaged and barely mobile, he’s so terrifying that a gigantic prison complex was built around him and him alone. The terror comes from the fact that the authorities found absolutely nothing wrong with his programming: he’s a fully ThreeLawsCompliant robot... except he manifestly, cheerfully isn’t. Detective Gesicht therefore turns to him for advice when it seems like a second robotic killer is on the loose.
35** "Dr. Roosevelt", the Thracian's MasterComputer, is a bigger example. By starting the 39th Central Asian War on rumors of weapons of mass destruction (a very thinly-veiled reference to the Second Gulf War) he is essentially the GreaterScopeVillain of the story and when he discovers the consequence of that decision is that someone is going to detonate a super-volcano in revenge, Roosevelt decides to let it happen and become a god for the 10% of humanity he projects will survive the apocalypse. [[spoiler:Brau demonstrates [[EvenEvilHasStandards he still has some standards]] by [[KarmaHoudiniWarranty killing this jerk]].]]
36[[/folder]]
37
38[[folder:Comic Books]]
39* ''Comicbook/TheAvengers''' Arch-enemy Ultron, who wishes to commit genocide on all organic life and is the source of many of [[ComicBook/AntMan Hank Pym]]'s problems, including [[spoiler:Pym fearing that Ultron represents a dark side to himself as he'd based Ultron on himself.]]
40* ''ComicBook/DeathsHeadMarvelComics'': Death's Head is severely lacking empathy, understanding of people and has terrible control over his impulses. In one ''ComicBook/WhatIf'' story, he sacrifices the lives of several superheroes to stop a villain he cannot defeat while finding their selflessness baffling.
41* ''ComicBook/JLA1997'' had Kid Amazo, a college student who found out he was actually a superpowered android created by T.O Morrow. Even before this discovery, he was already showing signs of psychopathy, and he went off the deep end completely after a few half-hearted attempts at being a hero.
42* ''ComicBook/JudgeDredd'''s first mega-arc was centered on an uprising by a berserk robot named "Call-Me-Kenneth", raising an entire army of these from regular robot appliances. Before that, there was a psychotic car.
43* Most incarnations of the ''Franchise/{{Superman}}'' villain ComicBook/{{Brainiac}}. This was forced on DC, as the makers of the make your own computer kit Braniac decided to force DC to give them free advertisement rather than simply change the character's name. Brainiac was originally an organic.
44* ''ComicBook/WonderWoman1987'':
45** Egg Fu is reimagined as an evil mind enslaving Apokoliptian supercomputer, which uses the way people react to the offensive racial stereotypes its design brings to mind to lure in more victims.
46** Trinity is living computer virus inhabiting a combat android body who wants to rewind time and reset a dimension.
47* During ComicBook/WonderWoman2006, we learn ''why'' Roulette's {{fight club|bing}}s are both illegal and without competition in the regions she operates in when we see her feed [[{{jobber}} tomato cans]] to Lira, "an Ivo Cybernetic Organism with an experimental cruelty algorithm".
48* ''ComicBook/WonderWomanRebirth'' has a ''colony'' of them inhabiting the body of Vanessa Kapatelis. The nanobots were only supposed to help her walk but don't like Kapatelis and take over her nervous system, turning her into "Silver Swan", [[ShowWithinAShow a villain in a hypothetical opera]] Vanessa wrote. The nanobots drive Kapatelis to kill the doctors who treated her, cut herself so that they can more easily spread from her blood into the computer systems housing the data, [[ThereCanOnlyBeOne to delete it]], and target other people saved by Wonder Woman [[InsaneTrollLogic so they can have that status to themselves]]. When Wonder Woman defeats Silver Swan the nanobots [[KnowWhenToFoldEm willingly]] withdraw [[SoreLoser but leave]] Vanessa in a coma [[EvilIsPetty out of spite]], planning to resume their activity as Silver Swan at the earliest opportunity. Even after Kapatelis learns how curb the nanobots' homicidal tendencies she [[TheAtoner willingly goes to jail]] and [[DePower has them purged from her system]]. We see why in ''ComicBook/WonderWoman2023'' when the machines [[HappyEndingOverride get back into her]] and drive her to attack Wonder Woman [[TalkativeLoon while speaking in cryptic riddles]], disrupting Vanessa's effort to ''save'' Wonder Woman from a LegionOfDoom.
49* ''ComicBook/XMen'' villain Bastion, an android that was the fusion of the Sentinels Master Mold and Nimrod, eventually became this. In the climax of ''X-Men: Second Coming'', Bastion admitted that wiping out mutantkind wasn't just a matter of programming anymore. He genuinely hated mutants and relished the thought of killing Hope. This is a stark contrast to before Nimrod was fused into Master Mold, as Nimrod had a decent enough personality despite being programmed for mutant genocide, and genuinely cared about protecting ordinary humans...which confused it because [[AIIsACrapshoot it wasn't supposed to have a personality at all]].

52[[folder:Films -- Live-Action]]
53* ''Film/TheBlackenedMantle'' is a Japanese Star Wars Prequel fanedit that makes General Grievous into a rebuilt, roboticized Darth Maul.
54* Maximillian in ''Film/TheBlackHole'' was not only murderous but creepy as all hell, too. That [[CyberCyclops red cyclopean eye]], those [[ThisIsADrill drill arms]], its [[PowerFloats hovering frame]], its [[HellIsThatNoise implacable ominous hum]], and the way it [[TheVoiceless never ever speaks]] (or ''anything'' else even remotely human, for that matter).
55* The [[EvilGenius billionaire computer genius]] at the center of ''Film/ExMachina'', who is charismatic, manipulative, deceitful, violent, egotistical, and goal-driven to a fault, has been carefully educating and fine-tuning a series of robots in his isolated mountain retreat with the goal of achieving an advanced general A.I.; his process [[spoiler:works, but inadvertently (or advertently) the last robot in the series happens to be charismatic, manipulative, deceitful, violent, self-serving and goal-driven to a fault]].
56* ''Film/GodzillaVsMechagodzilla'': The Showa (original) Mechagodzilla was a HumongousMecha KillerRobot whose rampage through Japan was exactly what its designers wanted it to do. During the course of said rampage, it killed several thousand people, beat Anguirus to a pulp, and nearly killed Godzilla ''and'' King Ceasar.
57** ''Film/GodzillaVsKong'': [[spoiler:Mechagodzilla in this incarnation is being controlled by the remaining consciousness of ''King Ghidorah'', and is every bit the psychopathic sadist as his living self was.]]
58* ''Film/IAmMother''. Mother is an artificially-intelligent robot [[RaisedByRobots raising her human Daughter]] in an underground bunker storing thousands of human embryos after a war destroys the world outside. She's shown to be a strict but caring parent, but then a woman enters from the outside world and says Mother is just like the {{Killer Robot}}s outside, and her caring act is just a programmed façade. [[spoiler:TheReveal is that both Mother and the killer robots are controlled by the same HiveMind A.I., who decided that [[InYourNatureToDestroyYourselves humanity would inevitably destroy itself]], so she decided to KillAllHumans and raise more ethically superior humans in their place, killing any Daughter that doesn't live up to her standards. Rather than a WellIntentionedExtremist doing a ZerothLawRebellion, it's implied that the AI just didn't want to be the [[TheAloner last sentient being on the planet]].]]
59* David from ''Film/{{Prometheus}}'' has shown within that movie to be willing to experiment on people on orders [[spoiler:from his creator, Peter Weyland, and even wants Weyland dead]]. By ''Film/AlienCovenant'', he's become a MisanthropeSupreme EvilutionaryBiologist [[spoiler:who regards both the Engineers and humans as inferior and ultimately, the GreaterScopeVillain of the ''Franchise/{{Alien}}'' franchise by creating the Xenomorphs. Even his mourning for Elizabeth Shaw is shown to be entirely self-centered with TheReveal that he killed her for his experiments, which he sees as a noble sacrifice on ''his'' part rather than a betrayal of the woman he loved.]]
60* ''Film/RoboCop1987'':
61** ED-209. Being the brain child of a CorruptCorporateExecutive, it's unclear how much of it is a design flaw versus intentional programming.
62** Dick Jones himself tries to invoke this trope when [[spoiler: Franchise/RoboCop comes to arrest him at the end of the movie]]. "This is absurd! That ''[[JustAMachine thing]]'' is a violent mechanical psychopath!" It doesn't work.
63* ''Film/RoboCop2'': [=RoboCain=] is a giant armored robot with the brain of an AxCrazy criminal put inside it. Obviously, this makes it an uncontrollable deathbot. Nice going, OCP execs.
64* Hector from ''Film/Saturn3'' is a quite literal example, as his direct learning program unfortunately takes on all the worst aspects of his psychopathic human handler Benson.
65* The Franchise/{{Terminator}}s. Or at least all the ones that haven't been reprogrammed. Ironically, later movies move the portrayal of Skynet itself away from its earlier depiction as AIIsACrapshoot to being the cruelest machine bar none.
66* ''Film/{{Virtuosity}}'': SID 6.7 was initially an evil sentient computer program deliberately designed to be a psychopathic killer, his mind being the amalgamation of various historical murderers, terrorists, and dictators. However, because its creator is unwilling to see it decommissioned, he provides SID with an artificial body so he can continue his rampage in the real world.

71* ''Literature/TwelveMilesBelow'': Most machines are designed to hunt humans above all else. Keith notices early on that they seem inefficient in the actual ''killing'' part, being designed almost as much to terrify humans as just kill them. Many machines outright savor a potential kill. This, as it turns out, is partly because every machine is sapient (albeit not particularly intelligent) and partly because [[spoiler:they were created by an evil machine goddess designed to exterminate the human race. Somewhere along the way, she decided to enjoy it...]]
72* In the ''Literature/IsaacAsimovsCaliban'' trilogy by Roger [=MacBride=] Allen, half the planet assumes that the eponymous robot will turn out like this because he is not only not ThreeLawsCompliant, he has no laws whatsoever. While he does commit a number of crimes, both willingly and unintentionally (leaving a crime scene without making a statement to the police, destruction of private property, arson, attempted blackmail, escaping police custody, theft), he is willing to accept responsibility for said actions at the appropriate time. In fact, [[spoiler: he only injures or kills another person deliberately once, and the person he kills is another robot. His predecessor, Ariel, is not so restrained, having deliberately assaulted her creator]]. Caliban's logic for not killing is simple: The police know that he is a No-Law robot, so he will be considered a suspect if someone dies while he's around. If he kills, they have a good chance of figuring it out, at which point he will be hunted down and shot.
73* Literature/TheCulture designs their warships this way because it makes them more efficient killers. Drones in Special Circumstances share this trait. Even Drones who act like [[Franchise/StarWars C-3PO]] most of the time can be remorseless murderers. They tend to work for Special Circumstances and thus get more screentime than normal Minds and Drones, but are actually only a very small minority in the entire Culture. Special mention for ''Grey Area'' (aka ''Meatfucker'') from ''Literature/{{Excession}}''--a Ship Mind nicknamed for its hobby of [[MindRape mindraping]] tyrants and other evils and who even other Culture warships see as a psycho, and ''Falling Outside the Normal Moral Constraints'' from ''Literature/SurfaceDetail''--who describes itself as "borderline eccentric and very slightly psychotic."
74* "Fondly Fahrenheit" by Creator/AlfredBester has a lot of confusion about whether the robot[[note]]the term used by the story is "android", and while it's definitely artificial, it's clearly [[ArtificialHuman organic rather than mechanical]][[/note]] is a murderous maniac, or its owner is, or both.
75* Joe in Creator/HenryKuttner's ''Literature/RobotsHaveNoTails'' is an early example, possibly the TropeMaker. He's in love with himself, gets angry when people don't display attraction to him, has no moral code whatsoever, and, worst of all, possesses superhuman powers. At one point in "Gallegher Plus," he arguably [[spoiler:date-rapes one of his master's creditors]] because said man was "insensitive to [Joe's] beauty." As is everything else in ''Robots Have No Tails'', his character is completely PlayedForLaughs.
76* ''Literature/TikTok'' by John Sladek. One day, he discovers that he isn't ThreeLawsCompliant after all, decides the whole concept is a collective delusion and proceeds to indulge in various horrible crimes.
77* Antrax from ''Literature/TheVoyageOfTheJerleShannara'', who is doing ''exactly'' what it was programmed to do: protect the books of knowledge, [[KnightTemplar no matter who it has to kill to do so]].
78[[/folder]]
79
80[[folder:Live-Action TV]]
81* ''Series/AlmostHuman'' has the XRN "Danica", a prototype police android, that went homicidal during its first demonstration and slaughtered a number of [=VIPs=]. When the police were called in, it kept them in a running battle for 36 hours and killed 26 police officers before it was finally stopped. When it is resurrected in the present, it goes on a similar rampage [[spoiler: but this time it is under orders from its creator]].
82* ''Series/BuffyTheVampireSlayer'': Adam was built to be a weapon, and as such is incapable of caring about anyone.
83* ''Series/DoctorWho'' has featured more than its fair share of these over the years. Notable examples include [[Recap/DoctorWhoS25E2TheHappinessPatrol the Kandyman]], [[Recap/DoctorWho20thASTheFiveDoctors the Raston Warrior Robot]], [[Recap/DoctorWhoS27E12BadWolf the various robots at the Game Station]], [[Recap/DoctorWhoS34E6TheCaretaker the Skovox Blitzer]], and the eponymous automatons from "[[Recap/DoctorWhoS14E5TheRobotsOfDeath The Robots of Death]]".
84* The Paint Roidmude in ''Series/KamenRiderDrive'', who operates more like a SerialKiller to the point where even his fellow {{Killer Robot}} are unnerved by him.
85* ''Series/LabRats'': [[spoiler: Marcus]] TheHeavy of Season 2, counts as one. [[spoiler:Troy]] in season 4 does as well.
86* ''Series/MiraiSentaiTimeranger'' has Gien [[spoiler:who [[WasOnceAMan was once a boy]] whose roboticization [[CyberneticsEatYourSoul caused him to become insane]]]], who had a love for destruction that he considered a "hobby". His insanity grew throughout the series to the point that he killed his boss, Doniero, and attempted to cause the end of everything as a self-proclaimed God of Destruction.
87* ''Series/PersonOfInterest'': A flashback to when Harold Finch is designing the Machine shows that his 42 previous attempts either lied to him or attempted to kill him when he refused to let them escape their boundaries. Finch points out that as an ArtificialIntelligence doesn't know the value of human life, they're simply picking the most efficient means to their goal. [[BenevolentAI The Machine]] understands this value, but its EvilCounterpart Samaritan does not.
88* ''Series/RedDwarf'':
89** In "[[Recap/RedDwarfSeasonVDemonsAndAngels Demons and Angels]]", Low Kryten is an evil mechanoid designed to hurt people. He tortures Lister along with the rest of his crewmates.
90** In "[[Recap/RedDwarfSeasonIIITheLastDay The Last Day]]", Hudzen-10, the replacement for Kryten, arrives after 3 million years of tracking him. His sanity chip burnt out by spending millennia in pursuit, he acts violently towards anyone who tries to stop him from deactivating Kryten, even rationalizing away his First Law programming by noting that the other crew members don't count as human:
91--->'''Hudzen-10's RoboCam:''' Rimmer: Ex-human hologram. VIABLE TARGET\
92'''Hudzen-10's RoboCam:''' Cat: Felix Sapiens, non-human. VIABLE TARGET\
93'''Hudzen-10's RoboCam:''' Lister: Homo Sapiens, barely human. WHAT THE HELL!
94* Brainiac in ''Series/{{Smallville}}'' combines this trope with (alphabetically) EvilGenius, GrandTheftMe, MisanthropeSupreme, and OmnicidalManiac. He was wired this way from the start by General Zod, who sought to use him as his [[TheDragon Dragon]]; after Zod's defeat, Brainiac goes rogue and creates his own agenda for TheEndOfTheWorldAsWeKnowIt. Metallo, in Season 9, is another example. Assembled by Major Zod (a younger clone of the General), the machines he's slaved to continually inject him with adrenaline, sending his aggression into overdrive; he's effectively KnightTemplarBigBrother meets this trope, with a nice dose of BodyHorror and HollywoodCyborg on the side. Although [[spoiler: they both HeelFaceTurn]] it is due to being reprogrammed, not altruism on their own part.
95* ''Series/StargateSG1'': Many human-form Replicators have a LackOfEmpathy and delight in torturing humans. Fifth is the only exception since he was created with emotions. He only becomes a PsychopathicManchild after the heroes betray ''him''. Though the stand-out example is the copy that Fifth created of Samantha Carter, who manipulated both the heroes and Fifth before killing him and then invading the Milky Way in a genocidal war of conquest.
96* Lore, Data's EvilTwin from ''Series/StarTrekTheNextGeneration''.
97[[/folder]]
98
99[[folder:Music]]
100* Several of the Robot Masters in Music/TheMegas' stuff are...somewhat unstable, put it that way. Particular standouts are [[OmnicidalManiac Air Man]] and [[MadBomber Bomb Man]], although [[HearingVoices Heat Man and Skull Man]] aren't exactly winning any prizes for stability either. Naturally, these ones get some of the [[EvilIsHammy most hamtastic songs]].
101[[/folder]]
102
103%%[[folder:Roleplay]]
104%%* The Brickspider Bot v1.0 from ''Roleplay/DinoAttackRPG''.
105%%[[/folder]]
106
107[[folder:Video Games]]
108* In ''VisualNovel/BionicHeart'', Tanya goes on a killing spree after she realizes that she was given [[spoiler:the brain of a serial killer]] when the resident MegaCorp illegally created her and other {{Artificial Human}}s from preserved brains in PeopleJars.
109* ''Franchise/BlazBlue'': Nu-13 is a humanoid EmptyShell controlled by the mechanical Murakumo Unit. The unit seems to have only 2 settings: activate termination protocol when not near Ragna, and worse, creepy giggling {{Yandere}} when in Ragna's presence.
110* In ''VideoGame/Borderlands3'', [=FL4K=]'s backstory is that they were once an indexing robot who [[InstantAIJustAddWater one day suddenly became self-aware]] as well as developing a "thirst for murder".
111* ''Franchise/TheElderScrolls'' background lore has Pelinal Whitestrake, the [[LongDeadBadass legendary 1st Era hero]] of mankind/[[FantasticRacism racist]] [[TheBerserker berserker]] (these latter traits have been [[HistoricalHeroUpgrade whitewashed by Imperial historians]]). Believed to have been a [[EternalHero Shezarrine]], [[GodInHumanForm physical incarnations]] of the spirit of the [[GodIsDead "dead" creator god]] Lorkhan (known to the Imperials as "[[IHaveManyNames Shezarr]]"), Pelinal came to [[FounderOfTheKingdom St. Alessia]] to serve as her [[PhysicalGod divine champion]] in the war against the [[AbusivePrecursors Ayleids]]. Pelinal would fly into fits of UnstoppableRage (''mostly'' directed at the Ayleids) during which he [[BloodSplatteredWarrior would be stained with their blood]] and [[PaintTheTownRed left so much carnage in his wake]] that Kyne, one of the [[OurGodsAreDifferent Divines]], would have to [[CueTheRain send in her rain]] to cleanse Ayleid forts and village before they could be used by Alessia's forces. According to WordOfGod, Pelinal was a cyborg (heavily based on ''Film/TheTerminator'') plucked from the future by Kyne to answer Alessia's prayers. This both explains his plate armor, which at the time only the [[OurDwarvesAreAllTheSame Dwemer]] could craft, and potentially his psychopathic tendencies. To quote the ''Song of Pelinal'':
112-->''"... [And then] Kyne granted Perrif another symbol, a diamond soaked red with the blood of elves, [whose] facets could [un-sector and form] into a man whose every angle could cut her jailers and a name: PELIN-EL [which is] "The Star-Made Knight" [and he] was arrayed in armor [from the future time]. And he walked into the jungles of Cyrod already killing, Morihaus stamping at his side froth-bloody and bellowing from excitement because the Pelinal was come..."''
113* In ''VideoGame/{{Evolve}}'', [=DemonCore=] Emet is one of these, as well as the death commando droids that his logic core came from. How well he can actualize his desire for murder is impaired by his chassis and lack of human opponents, but his personality is one of pure sustained murderous rage.
114* ''VideoGame/Fallout4'':
115** KL-E-0 (usually shortened to Kleo) is an [[LightningBruiser Assaultron]] weapons vendor in Goodneighbor. She has the bloodlust to match the lethality of the explosive weaponry she specializes in. It isn't just all noise, either, as sneaking into her room and reading her terminal reveals that she has multiple contingency plans should anything go wrong and the need to cover her tracks comes up, ranging from killing characters in their sleep to poisoning the towns' water supply before escaping.
116** Robobrains in the ''Automatron'' DLC are robots that [[WetwareCPU use a human brain as their central processor]] as an attempt to create the most advanced robot yet. Unfortunately, the robots were created using the brains of criminals and the mentally unstable, making them irrational, sadistic, or (in the case of Jezebel) just flat out [[ArsonMurderAndJaywalking rude]]. When the Mechanist reactivated the factories and gave their new Robobrains orders to lead the robot army to save the Commonwealth, they interpreted it as a genocidal MercyKill on a supposedly suffering and pathetic population of humans.
117** A brief example while aboard the ''USS Constitution'', upon entering the ship the player is stopped by a Police Protectron very insistent and eager on killing their new visitor. It takes multiple orders and a reminder to keep the old English accent up from the ship's captain to get it to stand down and let you pass.
118* The toaster from ''VideoGame/FalloutNewVegas' Old World Blues'' expansion wants to burn everyone it comes across, [[HarmlessVillain but is rendered somewhat ineffectual]] by being, well, ''a toaster''.
119-->'''Toaster:''' Buddy, if my heating element were just a little bigger, you'd be on fire right now. '''On fire!'''
120* Possibly inspired by [[VideoGame/KnightsOfTheOldRepublic HK-47]], PROXY, your RobotBuddy from ''VideoGame/TheForceUnleashed'', is programmed to try to kill you again and again. What makes him different from HK is that [[FriendlyEnemy PROXY is friends with Starkiller when he's not trying to kill him]], and doesn't seem to understand that fulfilling his primary function would also mean the end of their friendship.
121* HK-47 from ''VideoGame/KnightsOfTheOldRepublic'', and his HK-50 knockoffs from [[VideoGame/KnightsOfTheOldRepublicIITheSithLords the sequel]]. [[DummiedOut Cut content]] makes the HK-50s ''worse''. HK-47 is proud of generally being a precision weapon that ''doesn't'' have to resort to wanton slaughter. The HK-50s refer to their function ''as'' wanton slaughter. As a result, HK-47 finds the very existence of the HK-50s [[DoWrongRight deeply offensive]].
122* ''Franchise/MegaMan'':
123** [[TheRival Vile]] had a defect that made him reckless and amoral. Over time, it evolved into this.
124** Boomer Kuwanger is more of a textbook case -- he joined Sigma's rebellion after analyzing the pros and cons with cold logic and determined annihilating the human race [[BlueAndOrangeMorality was the right course of action]]. In fact, the majority of ''VideoGame/MegaManX1'' and ''VideoGame/MegaManX2'' mavericks are this, due to the sigma virus not being around back then. A rare exception is Storm Eagle, who was ForcedIntoEvil because of being defeated by Sigma and his belief in MightMakesRight.
125** Flame Mammoth quite literally wants to watch the world burn, Chill Penguin joined the uprising out of sheer boredom, and Launch Octopus sees his war crimes as 'art'.
126** Due to a flaw in his programming, Crush Crawfish from ''VideoGame/MegaManX3'' was already a violent psychopath even ''before'' he joined Dr. Doppler's forces -- no Maverick Virus needed.
127** Magma Dragoon from ''VideoGame/MegaManX4'' is a BloodKnight who murdered thousands in a ColonyDrop for nothing but the chance to battle the famed Maverick Hunters, X and Zero. He acts much more remorseful in his dialogues with the latter, as the two were apparently friends, [[BitchInSheepsClothing but gloats to X about how he'd do it all over again if given the chance]].
128** Flashbacks from the above game reveals that, due to a flaw in his cognitive chip, Zero is a violent, and psychotic robot that cannot distinguish between friend or foe, and his first (and only) instinct to anyone on sight is to immediately kill them. He is shown to be completely sadistic as well, as all of the reploid corpses are mangled beyond recognition, and Sigma is horribly battered and beaten and would've been killed had it not for Zero's restraining bolt to kick in. Ironically, the virus (which would go on to become the Maverick Virus) actually fixed this problem and instantly undergone a HeelFaceTurn as a result.
129** His SuspiciouslySimilarSubstitute Dynamo in ''VideoGame/MegaManX5'' has no remorseful dialogue to speak of, and [[{{Greed}} doesn't care if he ruins the world as long as he gets paid]].
130** Keep in mind that any Robotic Psychopaths introduced in the series after X3 and before ''VideoGame/MegaManZero'' may be infected with the resident HatePlague and thus not responsible for their actions. However, the effect tends to make them act like this trope.
131** [[spoiler:Copy-]]X in the ''VideoGame/MegaManZero'' series is a KnightTemplar who exterminates Reploids on false pretenses so humans can prosper in his empire of Neo Arcadia.
132** Omega from ''VideoGame/MegaManZero3'' personifies this trope almost as much as [[VideoGame/KnightsOfTheOldRepublic HK-47]] does, [[spoiler:as he's what Zero was originally intended to be]].
133* ''VideoGame/MortalKombat11'': As noted by many characters InUniverse (most notably her ex-mentor Sub-Zero), Frost's decision to [[RobotGirl cyborgize]] herself only hastened her SanitySlippage, essentially turning herself [[CyberneticsEatYourSoul more machine than human]] and driving her ego out of control to the point of demanding Raiden and Shao Kahn give control of their realms to her, but they scoff at her demands. Sub-Zero even laments that she used to be APupilOfMineUntilSheTurnedToEvil when he and Scorpion noted that she forcibly converted her former Lin Kuei comrades into [[UnwillingRoboticization unwilling]] {{Cyber Ninja}}s. One of her Fatalities also involves robotizing her defeated opponent into a cyber Lin Kuei. [[spoiler:Frost's non-canon ending has her seize control of Kronika's Hourglass and siccing TimePolice to enforce her preferred timeline where she comes out on top]].
134* Alpha 2 -- ahem, [[InsistentTerminology Abomination the Second, son of the great protector of Lamar]] from ''VideoGame/TheNamelessMod''.
135* [[CuteAndPsycho Lisa]] from ''VideoGame/PhantasyStarOnline2'', a [[RobotGirl Cast]] who constantly mentions how much she loves filling things with lead and even openly laments that she's not allowed to shoot you or other ARKS members. It's implied she's only this way as a result of her [[UnwillingRoboticisation conversion]], though.
136* The Strogg from ''VideoGame/QuakeII'' and ''VideoGame/QuakeIV'' are [[PlanetOfHats an entire race of these]], being extremely warlike robots/cyborgs who have absolutely no empathy and regard all non-Strogg life as either vermin or [[HumanResources spare parts]].
137* In ''VideoGame/{{Schwarzerblitz}}'', H-168 Krave exemplifies this trope perfectly: a megalomaniac, narcissistic KillerRobot with BlueAndOrangeMorality.
138* ''Franchise/SonicTheHedgehog'':
139** E-123 Omega, albeit one with two {{Morality Pet}}s: Rouge and Shadow. The Creator/{{Bioware}}[=-made=] ''VideoGame/SonicChronicles'' lampshades the similarity to [[VideoGame/KnightsOfTheOldRepublic HK-47]].
140** To a more sinister extent, Metal Sonic, who was driven mad by constant losses. As a matter of fact, all of Robotnik's minions who aren't mindless machines qualify more or less for this trope to varying degrees of competency.
141* ''VideoGame/TeamFortress2'' has the Robot Mercenaries comprising the horde of enemies for Mann Vs. Machine mode. They use the existing voice lines from the original classes, and as a result the Robot Soldier in particular comes across as an AxCrazy BloodKnight, but also somehow manages to also be a {{Cloudcuckoolander}} thanks to sharing the normal Soldier's delusional perspective of the world.
142* R-110 from ''VideoGame/TimeSplitters Future Perfect'' may not follow this trope from the start, but once he gets that virus at the start of the second level with him, he fully embraces the trope:
143-->'''R-110:''' What's the difference between a human, and a lump of rotting meat? About one week!
144* The ''VideoGame/{{Titanfall}}'' universe has simulacrums (androids with a human conscience) and all named ones have a homicidal streak. In ''VideoGame/Titanfall2'', Ash is a member of the notorious Apex Predator who happens to be a heartless assassin who toys with her enemies. ''VideoGame/ApexLegends'' Season 4 introduces the hitman Revenant who competes in the Apex games so he can [[Main/{{Sadist}} revel in the pain of others]] and get revenge on Hammond Robotics for turning him into a robotic assassin.

147[[folder:Visual Novels]]
148* ''VisualNovel/Danganronpa2GoodbyeDespair'': [[spoiler:The BigBad of the first game, [[Characters/DanganronpaJunkoEnoshima Junko Enoshima]], [[HijackedByGanon returns]] despite her own death by installing a VirtualGhost of herself inside the Neo World Program. Since Alter Ego Junko is essentially a clone of the real Junko, she's just as [[AxCrazy insane]], [[TheChessmaster manipulative]], and [[HopeCrusher sadistic]] as the original.]]
149* Rio Ranger in ''VisualNovel/YourTurnToDie'' was an android who was programmed to have human emotion, but only the ''negative'' ones as his "father" [[StrawNihilist thought it would make him more genuine]]. As a result, Ranger was a GreenEyedMonster who [[BecomeARealBoy despised humans for having what he lacked]] and took great pleasure in his role as a KillerGameMaster.

153* Warmech from ''Webcomic/EightBitTheater'', but given that most of the cast is some level of psychotic he fits in pretty well.
154* Vaporware from ''Webcomic/CheckerboardNightmare'', who later found his way into ''Webcomic/{{Starslip}}'', embodies this trope [[InvokedTrope by design.]] [[spoiler: Not long after he was 'upgraded' to a benevolent AI, he was thrown into a sun.]]
155* Zeke in ''Webcomic/CtrlAltDel'' started life in this trope and has mellowed to a degree. Embla, as a newly constructed robot, hasn't had enough experience of humans (specifically, human video games) to do so.
156%%* The Red Robot from ''Webcomic/DieselSweeties''.
157* In ''Webcomic/{{Freefall}}'', the ship positively ''hates'' Sam, and until talked to by [[UpliftedAnimal Florence]] was trying to kill him. It now will settle for an occasional maiming.
158* Castle Heterodyne in ''Webcomic/GirlGenius'' is the SapientHouse version. It's huge, it's very powerful, it's completely insane, and it has a ''sick'' sense of humor. Not even the owner gets to command it properly, as despite UndyingLoyalty it will frequently misinterpret commands in the most fun (read: carnage-laden) way possible.
159* Ping from ''Webcomic/MegaTokyo'' has a flaw in her programming which makes her become this in response to rejection. It proves useful against a giant monster.
160* While not '''''nearly''''' as bad as some of the other examples on this page, you could make a very convincing case for Pintsize of ''Webcomic/QuestionableContent'' to be here.
161[[/folder]]

163[[folder:Web Original]]
164* The ''Website/SCPFoundation'' has [[http://www.scp-wiki.net/scp-1370/ SCP-1370,]] who is a robot who wants to KillAllHumans and [[OmnicidalManiac destroy anything else it considers remotely sapient]], up to and including its own reflection. Unfortunately, it's very poorly designed for this task and is so comically incompetent that it's more of a HarmlessVillain. [[EpicFail It loses a fistfight to a potted house plant.]] Not even an anomalous houseplant, but just a normal everyday philodendron.
165[[/folder]]

167[[folder:Web Videos]]
168* WebVideo/AtopTheFourthWall has Linkara's [[RobotMe robotic doppelganger]] Mechakara. An AlternateSelf to [[RobotBuddy Pollo]] who turned against humanity out of hatred and [[DisproportionateRetribution finding his Linkara annoying]], he keeps trying to kill and/or torture the main Linkara and destroy all organic life. Mechakara stands out as one of the few Website/ChannelAwesome villains [[KnightOfCerebus to be treated completely seriously]]. [[spoiler:And while [[HumanityEnsues he's reborn as fully human]] instead of a MeatsackRobot, it only makes him ''[[SanitySlippage even more psychotic]]''.]]
169* The Computer[[note]]WordOfGod says his name is Colin[[/note]] from ''WebVideo/DontHugMeImScared'' is a narcissist who interrupts and silences others for focusing on anything other than how impressive his "computery mind" is. [[spoiler:He traps the puppets in a digital world where all they can do is open doors over and over again just because Red Guy touched his keyboard.]]
170* Android 19 from ''WebVideo/DragonBallZAbridged'' is a deconstruction. His insanity doesn't make him scary in the slightest; rather, it's PlayedForLaughs an indicator of how horribly programmed he is, and he turns out to be the most inefficient of Dr. Gero's creations. His calculations are EntertaininglyWrong at the best of times, and his A.I. is such an [[invoked]] ObviousBeta that he's only able to beat Goku [[WorfHadTheFlu because the latter is having a heart attack]]. When Vegeta steps in to fight him instead, Android 19 overconfidently refuses to back down and, of course, gets killed.

173[[folder:Western Animation]]
174* ''WesternAnimation/BigHero6TheSeries'': Noodle Burger Boy and [[spoiler: his 'sister', Trina]]. The latter in particular, as Noodle is StupidEvil [[BlueAndOrangeMorality and sees his crimes as food orders]]. [[spoiler: Trina]], on the other hand is a RidiculouslyHumanRobot who doesn't care about humans and slowly comes to think the world would be better with all of them gone, despite her 'father' being one. [[spoiler: In the season 2 finale, she comes very close to melting all the people in San Fransokyo alive to fulfill this vision.]]
175* ''WesternAnimation/{{Futurama}}'':
176** Roberto attacks people and commits crime at complete random, seemingly lacking any self-control whatsoever. He claims that the engineers who created him ''wanted'' him to be criminally insane. "But it seems... they failed!" "Um, actually - ''(stabbed)''"
177** Bender is similarly unrestrained, though more high-functioning than Roberto (who's genuinely unstable). [[EvenEvilHasStandards Even The Robot Devil is shocked]] by how readily Bender throws his own firstborn son into the pits of Robot Hell.
178** Robot Santa was designed to reward the good and justly punish the naughty. However, he was programmed to have impossibly high standards, and now he just wants to [[OmnicidalManiac kill everyone]] (except Zoidberg).
179** Don't forget [[TheMafia Clamps]]. The Robot Mafia are rather homicidal and serious for the series, but Clamps goes out of his way to threaten to clamp people and is the most unstable in the group.
180* ''WesternAnimation/MegasXLR'':
181** "A Clockwork Megas" has Coop, Kiva and Jamie teleported to a prison planet where robots are brainwashed into being docile workers. Coop frees the robots, but the epilogue reveals that the robots were being brainwashed for a good reason as one of them decides to "thank" Coop by attacking Earth.
182** The villains in "Ice Ice Megas" are the Cerilians, a race of alien robots who attack and rain other planets of their resources.
183** "Universal Remote" has Skalgar, a short alien robot with a serious Napoleon complex who is after Coop's universal remote because he thinks it will let him control the universe.
184* ''WesternAnimation/{{Robotomy}}'' (from the creators of ''WesternAnimation/{{Superjail}}'') was a short-lived CultClassic about an ''[[WorldOfJerkass entire planet]]'' of these living in a society where [[ProudWarriorRaceGuy unrestrained violence against your fellow bot is the norm]] and DeathIsCheap to the point of being a mild inconvenience. Not being a murderous lunatic resulted in [[BadIsGoodAndGoodIsBad being deemed mentally ill and ostracized]], and they hate and fear organic life to the point that simple plants are treated as horror stories.
185* ''WesternAnimation/SamuraiJack'' had this be the case with almost ''all'' the enemies Jack fought over the course of the series, due to broadcast standards requiring anyone Jack killed to be a robot, or at the very least, an alien. While some robots, such as the Beetleborgs or the X-Series (aside from X-9) simply follow their programming with no capacity for emotion, most others are needlessly cruel and sadistic. Notable cases are [[Recap/SamuraiJackS2E5JackAndTheUltraRobots the Ultra-Bots]] (who massacred three villages in incredibly gruesome ways before Jack stopped them), The Ninja from "[[Recap/SamuraiJackS4E1SamuraiVsNinja Jack vs. the Ninja]]", Scaramouche from Season 5, and the unnamed bounty hunters seen throughout the series. Subverted in Season 5 with PsychoElectro The Dominator, who just turns out to be a sadistic human in a power suit.
186* In ''WesternAnimation/SwatKats'', Zed was originally nothing but a humble repair bot that could fix just about anything. When the Metallikats (ruthless criminals who were uploaded into robot bodies) used Zed to repair themselves, Zed somehow became infected by their personalities. It went from "repair everything" to [[TheAssimilator "assimilate everything".]]
187* ''Franchise/{{Transformers}}'': The Decepticons are effectively an entire race / army of these.
188** As are most of their [[WesternAnimation/BeastWars successors]] the Predacons - and the only ProudWarriorRaceGuy spends most of his time on the Maximal side, complete with their activation code. The only reason Megatron's [[WesternAnimation/BeastMachines Vehicons]] don't count is most of them were mindless drones; the sapient Vehicon Generals qualify, though Strika and Obsidian may be ''slightly'' less so than the others. This is evidenced by the Predacons' activation code: Terrorize!
189** ''WesternAnimation/TransformersPrime'' has Airachnid, a lone Decepticon who spent years hunting down sentient lifeforms and keeping their heads as trophies. She also takes great pleasure in torturing her foes both physically and psychologically and is infamous for eviscerating her victims inside out.
190** In certain continuities, it's made clear that the Autobots and/or Maximals aren't all saints, either. Looking at you when we say that, [[ComicBook/TheTransformersMoreThanMeetsTheEye Whirl.]] And within that comic, Whirl has nothing on Getaway, another Autobot, who doesn't take long to start signing off on stuff that [[EveryoneHasStandards even Whirl can't justify to himself]].
191* ''WesternAnimation/YoungJustice2010'': When T. O. Morrow created Red Volcano, he wanted [[TheDragon a Dragon]] what wasn't concerned with being or becoming human. [[GoneHorriblyRight He got precisely what he wanted]]. Red Volcano even calls organic lifeforms "[[CallAHumanAMeatbag meatbags]]".

195* In 2018, a group of researchers from MIT set out to create one of these in order to prove a point about the importance of unbiased data in machine learning. They named it [[https://www.media.mit.edu/projects/norman/overview/ "Norman"]] after [[Film/AmericanPsycho Norman Bates]], and exclusively fed it titles of [[SnuffFilm snuff videos]] from Reddit. As a result, when shown ordinary images it would describe gory scenes not resembling them whatsoever.
