* 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 her feed [[{{jobber}} tomato cans]] to Lira, "an Ivo Cybernetic Organism with an experimental cruelty algorithm".

* ''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]] 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.

* ''During ComicBook/WonderWomanRebirth'' Vanessa Kapatelis volunteers for nanobot therapy that allows her to walk again, but the machines don't like her and take over her nervous system, turning her into "Silver Swan", [[ShowWithinAShow a villain in a hypothetical opera]] Kapatelis 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]] but leave Vanessa in a coma [[EvilIsPetty out of spite]], planning to resume their activity as Silver Swan at the earliest opporitunity. 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 micro machines [[HappyEndingOverride get back into her]] and drive her to attack Wonder Woman [[TalkativeLoon while speaking in cryptic riddles]] corrupting Vanessa's intention to ''save'' Wonder Woman from a LegionOfDoom.

Subtrope of KillerRobot. Compare and contrast EccentricAI, which may be just as crazy but non-violent, or alternatively a Robotic Psychopath may be perfectly sane aside from their AxCrazy-ness.

* The Brickspider Bot v1.0 from ''Roleplay/DinoAttackRPG''.

* Brau 1589 from ''Manga/{{Pluto}}'', 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.

* ''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.

* ''VideoGame/MortalKombat11'': As noted by many characters InUniverse (most notably Sub-Zero, who used to be her mentor), Frost's decision to turn herself into a RobotGirl only hastened her SanitySlippage, essentially turning herself [[CyberneticsEatYourSoul more machine than human]]. Her cyborgization has made her more insane to the point of insisting 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.

* ''Comicbook/TheAvengers''' Arch-enemy ComicBook/{{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.]]
* ComicBook/DeathsHead 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.

* ''VisualNovel/Danganronpa2GoodbyeDespair'': [[spoiler:The BigBad of the first game, [[Characters/DanganronpaJunkoEnoshima Junko Enoshima]], [[HijackedByGanon returns]] despite her own death by installing an [[ArtificialIntelligence Alter Ego]] 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.]]

* The ''Website/SCPFoundation'' has [[http://www.scp-wiki.net/scp-1370/ SCP-1370,]] who is a robot who wants to [[VideoGame/DestroyAllHumans kill all humans]] and [[OmnicidalManiac more or less destroy anything else it considers sapient]]. 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.]]

* ''Tik-Tok'' 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.

* 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 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.

* ''VideoGame/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.
