13Examples of AxCrazy in Western Animation.
14----
15* ''WesternAnimation/AdventureTime'':
16** [[spoiler:Simon Petrikov as]] the [[Characters/AdventureTimeIceKing Ice King]]. His homicidally dangerous and mentally unstable behavior is mostly due to his insanity and dementia thanks to the influence of his crown, with the Ice King being too insane to even know what he's really doing.
17** While Lemongrab is usually more weird and disturbed than dangerous, on his bad days he becomes dangerously unhinged and violent to the point of almost devouring his own brother. He is worse in "Too Old", becoming a completely AxCrazy dictator who is very open to sadism and senseless violence. Fortunately, he returns to being sympathetic once he is fused with his brother.
18** Flame Princess. Whether you think she is good or evil, it's clear she enjoys burning things a little too much, made abundantly clear after she goes on a rampage in "Vault of Bones".
19** [[Characters/AdventureTimeTheLich The Lich]]. While outwardly calmer and more composed than other villains, he's been killing on a planetary scale for a very long period of time, and his ultimate goal is [[OmnicidalManiac the absolute is the eradication of all life]].
20** When the King Man was the Magic Man, he was an absolutely {{sadist}}ic maniac who amused himself by doing horrible things to others with his magic, and he did so with clear jovial glee.
21** [[PsychoForHire Me-Mow]] is a sadistic assassin who gleefully loves her job — which involves killing people.
22* ''WesternAnimation/TheAmazingWorldOfGumball'':
23** Nicole Watterson. Several episodes have shown that she can become dangerously insane and even ''homicidal''. She once went on a dangerous rampage in the supermarket after Richard tried to get the kids to steal candy to spite her.
24** Though Ocho's [[HairTriggerTemper explosive temper]] was previously established, in "The Uncle" he comes off as a psychotic delinquent who starts fights unprovoked, [[EvilHasABadSenseOfHumor pretends to kidnap someone as a "prank"]], and was implied to have wanted Gumball to beat Darwin with a hammer just to prove his friendship with Ocho was more important.
25%% ** Jamie, particularly in the CuteAndPsycho variation.
26** In "The Deal", it’s revealed that Gumball, Darwin, and Anais become completely and utterly psychotic (to the point of frightening Nicole of all people) when there’s nobody to keep them in line. They destroy everything in the house and try to launch the neighbor with a giant slingshot. Only Richard knows how to control them.
27* ''WesternAnimation/AmericanDad'':
28** Barry Robinson, when he's not medicated. However, his true personality isn't completely held off by the meds. Even with his usual "simpleton" demeanor, he occasionally slips out a psychopathic thought or two.
29** Principal Brian Lewis, an ex-convict who has been shown drinking on the job, dealing drugs, assaulting students, and murdering more than a few people over the course of the show.
30* ''WesternAnimation/{{Arcane}}'': Jinx as a teenager. She’s unpredictable to all, usually with explosive and/or deadly consequences.
31* ''WesternAnimation/{{Archer}}'' gives us Cheryl (who sometimes answers to "Carol", "Carina", "Cristal", and possibly a host of other names). She's a compulsive {{Pyromaniac}}, gets off on suffering physical and emotional violence, once spent 6 months believing that she was a werewolf, and is more often than not stoned out of her skull on either rubber cement or LSD-laced Gummi Bears (or both.) Luckily for everyone else at the company, she seems to get off more on her own pain than anyone else's. There's also Barry, who appears to have two personalities and has murdered several people, including the entire staff of a space station.
32* Around the end of ''WesternAnimation/AvatarTheLastAirbender'' [[spoiler: [[Characters/AvatarTheLastAirbenderPrincessAzula Azula]] definitely qualifies, having absolutely lost it after Mai and Ty Lee betrayed her. She has an absolute [[VillainousBreakdown breakdown]] before her final battle with Zuko and Katara]]. Ozai also counts as this as while he’s usually very self-controlled, if {{sadist}}ic and short tempered, his glee at [[spoiler:torching the Earth Kingdom in the climax]] shows just how much of a violent, [[TheSociopath sociopathic]] madman he is just inches beneath the surface.
33* ''WesternAnimation/BatmanTheAnimatedSeries'': [[Characters/DCAUPoisonIvy Poison Ivy]] near the end of her [[Recap/BatmanTheAnimatedSeriesE5PrettyPoison debut episode]]. Her [[TheTease sensual, sultry]] disposition evaporates the moment Batman kicks her to the ground. After which we see the volatile murderess she is underneath on full display, unloading crossbow arrows at him.
34* Rampage of ''WesternAnimation/BeastWars'' flips between this and a BloodKnight. Originally, he attempted to kill anything in sight, no matter whether they were Maximals or Predacons. In fact, the only reason he joined the Predacons after his first appearance was because Megatron held his life in his hands by removing his spark and keeping it for torture/incentive for Rampage to serve him, otherwise he'd probably try to kill them all. The fact he's one of the most heavily armed Transformers in the series doesn't help. He even mentions being a cannibal!
35** Then there's Inferno, Megatron's {{Pyromaniac}} [[TheDragon Dragon]]. To wit:
36--> ''"[[ChewingTheScenery Burn in the fires of Inferno]]!!!"''
37** In the sequel, ''WesternAnimation/BeastMachines'', we were introduced to Jetstorm, a LaughablyEvil LargeHam, who was utterly and completely nuts. He never stopped laughing, tossed off cheerful one-liners while trying to massacre his enemies, and when asked to HeelFaceTurn, attempted to dismember the person who made the offer. This is what happens when you take a KnightInShiningArmor like [[spoiler:Silverbolt]] and leave him BrainwashedAndCrazy.
38* In ''WesternAnimation/BeavisAndButthead'', the crazy old farmer who appears in episodes "Cow Tipping" and "Bungholio: Lord of the Harvest". And '''how'''. He manages to make ''Beavis'' look sane by comparison.
39* Kevin 11 in the original ''WesternAnimation/Ben10'' is an EnfantTerrible who gets off on inflicting violence and pain on others. To a lesser extent, there's also [[BigBad Vilgax]], who always keeps his composure but also [[{{Sadist}} clearly derives pleasure from causing death and destruction]].
40* ''WesternAnimation/TheBoondocks'': [[CreepyChild Lamilton]] [[EnfantTerrible Taeshawn]]. His extreme [[TheSociopath sociopathy]] actually scares [[{{Delinquent}} Riley Freeman]], which should say a lot.
41** All three members of [[TerribleTrio the Hateocracy]], as well as [[GrumpyOldman Colonel H. Stinkmeaner]] himself.
42** Jin Rummy and Ed Wuncler III. They're milder examples than those listed above, but it's still obvious that they're mentally unstable and violent.
43* ''WesternAnimation/CatDog'': Cat in "Monster Truck Folly" ends up attacking everyone unprovoked.
44* ''WesternAnimation/CourageTheCowardlyDog'':
45** Katz, as expected from a psychopathic SerialKiller with a [[{{sadist}} sadistic]] streak. His first appearance had him ''feeding the residents of his hotel'' to spiders, and to remind you this is his ''first appearance''.
46** Freaky Fred as well. The fact the only thing he'll murder is your hair does not help as much as it should.
47** Then we have a lot of unhinged psychos such as Le Quack, Benton Tarentella, the Great Fusilli, Shwick, Basil and Doctor Gerbil.
48* The [[EraSpecificPersonality early version]] of WesternAnimation/DaffyDuck was usually a fairly [[CloudCuckoolander harmless nutcase]], but in "WesternAnimation/TheDaffyDoc" he loses his job as a doctor's assistant and proceeds to knock WesternAnimation/PorkyPig out, smuggle him into the hospital, and attempt "surgery" on him ''with a saw'' to prove how capable he is.
49--> "[[MadnessMantra Where's a patient? Where's a patient? I gotta find a patient. I gotta find a patient]]."
50* ''WesternAnimation/DanVs'': Dan himself, as well as many other characters he vows revenge on.
51* ''WesternAnimation/DannyPhantom'' has Danny's [[PsychoForHire evil]] [[BadFuture future]] [[FutureMeScaresMe self]] as this. The first thing he did upon "reawakening"? Steal the ghostly half of BigBad Vlad Masters (OurGhostsAreDifferent is in full force here) and then kill his human half in front of Vlad, who viewed Danny as a surrogate son. In his first scenes, he kills at least a dozen people as well and spends much of the episode killing or planning to kill some more. The fact that even Vlad refuses to tell Danny how his human half died speaks ''volumes''.
52%% * In ''WesternAnimation/{{Daria}}'', Ms. Angela Li is this in "Fizz Ed".
53* WesternAnimation/DarkwingDuck's foe [[EvilTwin Negaduck]] is about as close to [[BadButt a kid-safe]] Ax Crazy as you can get, especially considering it's a Creator/{{Disney}} show. Negaduck's favored weapon, for example, is a chainsaw, and he takes great delight in attempting to blast cute fuzzy bunnies with a shotgun. This may or may not be a case of being a product of his environment.
54** Negaverse Launchpad? Happy with [[WouldHurtAChild firing a bazooka at cute little girls]]. The Muddlefoot family? Tank's okay as a non-evil twin, but Herb, Binky, and Honker were shown with a row of severed duck heads on a pole in their yard. With their beaks sewn shut.
55** And let's not forget Darkwing's home grown supervillain, Quackerjack, who's just about as crazy as you could come (thought not nearly as crazy as Negaduck). He'll take any toy, make it dangerous, and use it to commit crimes of all sorts, not to mention he's constantly laughing at how much misfortune he's causing for others.
56* Creator/{{Disney}}'s classic ''WesternAnimation/MickeyAndTheBeanstalk'' features WesternAnimation/DonaldDuck near the start, almost delusional from hunger. It's one of his most dynamic moments; some find it hilarious, others quite a bit creepy. [[https://www.youtube.com/watch?v=KqEVYbPw9lI See it here.]]
57* In ''WesternAnimation/DrawnTogether'' , the mall policeman in the episode "The Lemon-AIDS Walk". At first he seems very relaxed, but suddenly points a gun at a woman and threatens to kill her if Wooldoor refused to throw some candy. When Wooldoor is captured, the policeman killed the women anyway just for the pleasure.
58** A number of the Drawn Together housemates qualify for this, with Captain Hero, who destroyed his home planet out of ''spite'', being the most obvious.
59* ''WesternAnimation/EdEddNEddy'': [[spoiler:Eddy's Brother]] from ''WesternAnimation/EdEddNEddysBigPictureShow''. A twisted ChildHater who [[{{sadist}} loves]] tormenting Eddy both physically and mentally.
60* ''WesternAnimation/TheFairlyOddParents''.
61** Vicky. She's a crazed psychopath who will go above and beyond to torture kids ForTheEvulz.
62** Wanda. Specially when she is mad, demonstrates the sanity that she has, or rather, lacking. Not to mention she also demonstrates extremely {{sadist}}ic tendencies. Especially in the episode "A Bad Case Of Diary-Uh!" when she finds out that Vicky called her a "fat pink squirrel".
63** Also, [[{{Yandere}} Princess Mandie]]. Mark Chang leaving her at the altar drove her into a perpetual homicidal rage.
64** And Trixie in the episode "Just The Two Of Us". After Timmy wishes that he and Trixie were the only people left on Earth, she had a massive psychotic breakdown over having nobody to tell her she's pretty.
65%% ** [[UsefulNotes/GeorgeWashington MUST CHOP WOOD!]]
66** Crocker as well. While he is normally unhinged and a tall-order SadistTeacher, it becomes especially apparent in "The Secret Origin of Denzel Crocker" (where he subjects his students to all number of sadistic punishments, like making Timmy sit on a stool surrounded by [[BewareOfViciousDog rabid dogs]], because it's his most hated day of the year) and in TheMovie ''WesternAnimation/AbraCatastrophe'' (where he does things like turn his students into ice sculptures and ''toilets'').
67* ''WesternAnimation/FamilyGuy'':
68** In early seasons, [[Characters/FamilyGuyStewieGriffin Stewie Griffin]] was an extremely {{sadist}}ic, deranged, homicidal baby psychopath obsessed with killing his mother, had a penchant for random violence, and did not hesitate to commit murder or torture if it brought him closer to his goals. He certainly has gotten [[TookALevelInKindness saner and nicer]] over time, but it's still there.
69** Peter has shown multiple signs of being this in the later episodes. His idea of helping children to recycle is to dress up like a cougar and then threaten them at gunpoint until one of them does it.
70** Meg too, out of a desperation for love and affection, which is semi-{{Justified|Trope}} and understandable since she seldom receives love and affection.
71** Lois, when they ran out of paper towels on Christmas. Her rampage gave police enough reason to use tranquilisers meant for ''bull elephants''.
72** Stewie's evil clone, Evil Stewie, is a homicidal {{sadist}} who willingly commits torture and murder ''in his first few seconds on-screen''. In many ways, he's like the Stewie Griffin of the first seasons, with all of his unbridled sadism and homicidal impulses intact.
73** And we also have Jeff Fecalman, the DomesticAbuser of Quagmire's sister, who beats her [[DisproportionateRetribution for the smallest things]], also willing to kill in cold blood.
74** "A Fistful of Meg" gives us "Mental" Mike Palanski, who is shown to be a screaming lunatic who is capable of murdering even the school's resident tough guys. He's practically Jeff 2.0!
75** A [[https://www.youtube.com/watch?v=xwEXtSCKkTM cutaway gag]] shows that UsefulNotes/DavyCrockett was like this.
76* ''WesternAnimation/FostersHomeForImaginaryFriends''
77%% ** Berry. [[CuteAndPsycho Her appearance is not what she really is.]]
78** Mac's personality goes from a very NiceGuy to completely lunatic if he gets even the smallest amount of sugar.
79* Wendell from ''WesternAnimation/FriskyDingo'' is very definitely this. He randomly kills people for no conceivable reason, offers to abort a baby with a machete, then when said baby is born and revealed as a gigantic ant larvae monster, he rides it to the location of a doomsday device to destroy the Earth... just BECAUSE. With his pants off no less, commenting throughout on how wrong it is but how he's going to continue to do it.
80* ''WesternAnimation/{{Futurama}}''
81** Roberto, the dangerously insane, [[RoboticPsychopath psychopathic robot]] whose literal function is to stab others (there's a reason he resembles a tombstone). His many insane acts includes robbing the same bank three times in a row, killing other robots to provide a disguise for himself, and "practicin' my stabbin"! Not that it's truly his fault; whatever idiot built him ''programmed'' him to be a sociopath.
82-->'''Roberto:''' I'm thinking of a number between 1 and 10. Guess it, and you die first.\
83'''Bender:''' Uh....56?\
84'''Roberto:''' 56?? 56?! Now that's all I can think about! I'LL KILL YOU!
85** Then there's Robot Santa, who comes to kill people he considers naughty every Christmas, with his standard of what qualifies as "naughty" being ridiculously low.
86** Zoidberg's race go Ax Crazy during their mating season.
87* Creator/{{Disney}} one-upped itself in ''WesternAnimation/{{Gargoyles}}'', with Demona. During the City of Stone arc, she manages to turn all the humans in UsefulNotes/NewYorkCity [[TakenForGranite to stone]], and then is seen roaming the streets, casually destroying humans-turned-to-stone with a huge mace.
88** From the same series, [[QuirkyMinibossSquad Jackal and Hyena]]. At least Demona has ''[[FreudianExcuse/WesternAnimation reasons]]'' for being as whacked as she is -- these two just seem to kill people/hurt people/blow stuff up [[ForTheEvulz for the thrill of it]] ([[PsychoForHire and the paycheck, too -- but mostly the thrill]]).
89%%* Cobra Commander in ''WesternAnimation/GIJoeResolute''.
90* ''WesternAnimation/GravityFalls'':
91** Bill Cipher is a psychopathic, [[OmnicidalManiac omnicidal]] creature who enjoys pain and destruction.
92-->'''Gideon:''' YoureInsane
93-->'''Bill Cipher:''' [[CardCarryingVillain Sure I am.]] What's your point?
94*** He literally ''pulls the teeth out of a deer's mouth'' and presents them to Gideon with a cheerful "for you!"
95*** There's also Dipper's comment from "Weirdmageddon: Part 2" on some rather questionable glitter rain: "Knowing Bill, it's probably just bones, or ground up babies, or something."
96*** And let's not forget about how he rearranged the face of someone on a whim, [[AndIMustScream removing their mouth.]]
97* ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'':
98** [[EnfanteTerrible Mandy]], a pretty sadistic and rather [[TheNapoleon abusive and short-statured]] girl. She has no powers of her own, but is frightening enough to scare most beings who do. She once possessed Milkshakes and clawed Billy's eyes out in retaliation for him possessing ''her''.
99** Billy is very ChaoticStupid, and on his worst days, dives headfirst into psychotic territory. It's especially notable with [[AbusiveParents his treatment]] of his "son" Jeff the spider (granted, Billy has extreme arachnophobia).
100--->'''Jeff:''' ''(as Billy is jabbing him in the eyes with a broomstick)'' Why won't you love me, Dad?! I'll be anything you want me to be!\
101'''Billy:''' I ''WANT YOU'' TO BE ''DEAD''!
102* Flippy from ''WebAnimation/HappyTreeFriends'', if reminded of the W.A.R. (and nearly ''everything'' reminds him of it). Over the course of the series, he has brutally murdered numerous innocent characters in a variety of ways that are [[CruelAndUnusualDeath as creative as they are gruesome]].
103* ''WesternAnimation/HarleyQuinn2019'': [[Characters/HarleyQuinn2019TheCharacter Harley]] of course. As one might expect from the Joker's former top enforcer, she's short-tempered, unstable, and gleefully, eye-wateringly violent. As if to accentuate how violently insane she is, her happiest memory is apparently chopping one of her dolls' heads off with a cleaver when she was six.
104%% * Curly from ''WesternAnimation/HeyArnold'' is hinted to be this at times. Helga on occasion too, specifically in "Helga's Parrot".
105* [[Characters/InvaderZimZim The eponymous character]] of ''WesternAnimation/InvaderZim'': Ax Crazy, PsychoForHire, and MadScientist, all rolled into one. Which ''would'' make him a {{Magnificent|Bastard}} badass, if he wasn't also [[MikeNelsonDestroyerOfWorlds hyper-incompetent]], [[LordErrorProne incredibly narcissistic]], and a frequent ButtMonkey, as well.
106** Gaz also counts given she once happily used a device that could destroy the world and was disappointed when it failed to work. And then there's what she did to Iggins. Poor Iggins. He really should have listened to Gaz's warnings.
107* Itchy from ''JustForFun/TheItchyAndScratchyShow''. Itchy is a mixture of Ax Crazy and a [[TheSociopath sociopath]], {{sadist}}ically killing Scratchy in various painful ways, and with different instruments: chainsaws, axes, guns, etc.. And the worst is that it only does it [[ForTheEvulz for fun]].
108* The Monkey King from ''WesternAnimation/JackieChanAdventures''. At first, he seems like just a [[ThePrankster prankster]], but before long he's going after Jackie and Jade with an actual axe.
109* Heloise on ''WesternAnimation/JimmyTwoShoes'' is a malicious EnfanteTerrible who loves spreading misery as much as her boss. The only person she doesn't want to hurt is [[MoralityPet Jimmy]], and even he's not completely safe from her wrath. Also, Saffi gets this way around statues [[CloudCuckoolander (although she already is pretty loony when at peace)]].
110* Mr. Cat from ''WesternAnimation/{{Kaeloo}}''. He owns a large number of weapons such as bazookas, chainsaws, guns, and the like, and spends half of each episode [[FamilyUnfriendlyViolence using]] [[BloodlessCarnage them]] on [[NighInvulnerable Quack Quack]].
111* ''WesternAnimation/KingOfTheHill''
112** [[Characters/KingOfTheHillDaleGribble Dale Gribble]] is a bit of a mild example from this series. Dale is a major ConspiracyTheorist who thinks that everything and everyone is out to get him. He is also the most prone to threatening to kill others including his own friends and has been described as "mentally unstable" numerous times throughout the series. It doesn't help he's a professional exterminator and carries more guns than a regular person should need.
113** Mad Dog is basically Dale when he loses any small bit of sanity he has left. This dude is more prone to kill others when pushed too far (and that's a VERY thin line to cross) and even holds other people hostage when he doesn't get this way. You know you're crazy when it's ''[[DirtyCoward Dale]]'' that has to be the one to save you.
114** Jimmy Whichard is definitely not right in the head. It's clear he's mentally unstable but is way more prone to violent outbursts than others.
115** However, the character that tops ALL of these characters above is Leanne Platter, Luanne's violent, alcoholic, jailbird mother. From having beaten up her ex-husband Hoyt every day while they were married to attacking her daughter's boyfriend with a fork after he rejects her advances to having an EXTREME HairTriggerTemper to [[spoiler:literally pouncing on Peggy]] to making a mess wherever she goes, it's safe to say that's she's not entirely stable.
116* Luan Loud of ''WesternAnimation/TheLoudHouse'' on April 1st, A.K.A. April Fools'. If you're with the Louds on April 1st after the events of Silence of the Luans, no joke, [[GodHelpUsAll may God have mercy on you]].
117%%* Robex the Cut-Throat from ''WesternAnimation/OrsonAndOlivia''.
118%%* Rico from ''WesternAnimation/ThePenguinsOfMadagascar''. Lampshaded by Skipper.
119* Mojo Jojo from ''WesternAnimation/ThePowerpuffGirls''. He's extremely homicidal and explodes into violent tantrums when frustrated.
120* Benson from ''WesternAnimation/RegularShow'' becomes this at times. His HairTriggerTemper is so extreme that he reaches many times a psychotic behavior.
121* ''WesternAnimation/TheRenAndStimpyShow'':
122** Ren himself. He's usually prone to psychotic fits of fury for little to no reason at times. He's even willing to ''kill'' anyone. This is not PlayedForLaughs in some episodes, however.
123** George Liquor, The Fire Chief and Haggis [=McHaggis=] as well.
124* [[Characters/RickAndMortyRickSanchez Rick Sanchez]] from ''WesternAnimation/RickAndMorty''. He has been shown on multiple occasions to go absolutely berserk and overboard upon provocation, including ripping off the equivalent of a robot's testicles and shoving it down said robot's throat when tipped off to the police, engaging in cross-dimensional crossfire with himself when he thinks that other versions of him are trying to kill him, literally going Ax-Crazy and violently murdering various clones of himself (including [[WouldHurtAChild a child and an infant]]), exploding an entire alien colonisation for putting him in a simulation and creating accurate genitalia for his grandson Morty, destroying an entire universe in order to spite its creator, programming his space-car to torture and murder in cruel and horrific ways or manipulate/coerce people into staying away from it when advised and committing countless other atrocities.
125** His daughter [[Characters/RickAndMortyBethSmith Beth Smith]] is this as well, possibly even worse. As Rick puts it and gives her ample evidence of being Ax-Crazy:
126--> ''"Bad father all the way to the max over here. I’m a fucking nutcase. And the acorn plopped straight down, baby. Look at some of this shit you were asking me to make you as a kid. Ray guns, a whip that forces people to like you, invisibility cuffs, a parent trap, a lightning gun, a teddy bear with anatomically correct innards, night-vision googly-eye glasses, sound-erasing sneakers, false fingerprints, fall-asleep darts, a lie-detecting doll, an indestructible baseball bat, a taser shaped like a ladybug, a fake police badge, location-tracking stickers, rainbow-colored duct tape, mind-control hair clips, poison gum, a pink sentient switchblade."''
127** Even his grandson [[Characters/RickAndMortyMortySmith Morty Smith]] has shown shades of this: when he gets pushed and loses his sense of morality he becomes a homicidal lunatic.
128* ''WesternAnimation/RockosModernLife'': Rocko and Heffer are on a bus tour of UsefulNotes/{{Paris}} with a bus driver who is determined to keep his passengers on the bus ''at all costs'', so much so that he chases them around the city after they escape.
129* ''WesternAnimation/SamuraiJack''
130** [[Characters/SamuraiJackAku Aku]] is a sadistic demon who commits carnage and torture [[ForTheEvulz for his own sick entertainment]]. In "Jack and the Zombies", he's very much the living embodiment of this trope. Notice his maniacal cackling while fighting Jack. During the beginning of the fight, Aku's laugh is absolutely [[LaughingMad psychotic]], and then he goes on a murderous rampage.
131-->'''Aku:''' "Oh Samurai? Where are you Sa-mu-rai? You can run but you cannot hide, CAUSE I CAN SMELL YOUR BLOOD!"
132** The HighPriestess is the psychopathic leader of the [[Characters/SamuraiJackCultOfAku Cult of Aku]]. Was the fact that she is the leader of a cult that worships the evolved form of a demonic entity, who abusively trains her seven daughters to be assassins of that entity any indication? [[spoiler:When even '''Aku''' is surprised by her willingness to drink his essence, it says something about her insanity]].
133** [[TheHeavy Scaramouche the Merciless]] is a {{sadist}}ic [[RoboticPsychopath Psychopath]] [[PsychoForHire For Hire]] who slaughtered a village filled with innocent men, women, and children. When Jack confronts him, he reveals he did this days ago, and has been casually waiting for him (Jack) to show up.
134** The Dominator, from "Episode XCVI", is a psychopathic man in Aku's employ who gleefully slaughtered an entire village just to start his plan. He's also an unbridled {{sadist}} to the point of getting off on enslaving children with audio frecuency and irrationally torturing Ashi [[ForTheEvulz for no reason]].
135* ''WesternAnimation/TheSimpsons'':
136** Groundskeeper Willy is just one {{hair trigger|Temper}} away from becoming this trope.
137** Sideshow Bob started to qualify for this when his attempts to [[WouldHurtAChild kill Bart]] included trying to have him ''cremated alive'' and when he visibly ''removed his cellmate's face and cut off his own''. He also ties up Bart while singing casually about wanting to [[EyeScream gouge out Bart's eyes]]. And then there's the "Treehouse of Horror XXVI" segment "Wanted: Dead, Then Alive" which has several moments that are genuinely disturbing. First, Sideshow Bob finally kills Bart. And it's not an over the top, comically ridiculous death, but fairly realistic. Bart gets harpooned through the heart, and since that doesn't immediately do the trick, Bob RETRACTS the harpoon and RIPS HIS HEART OUT. He then tears out Bart's large intestine and dances around with it while singing about how happy he is that Bart's dead before using it to tie his corpse to himself like a harness. It's also then revealed that Bob has kept Bart's corpse as it starts to decompose, eventually stuffing him in a compartment in the wall, even talking to him and playing golf with his body like he was alive. To make it worse, Bob revives Bart and then kills him again in various other ways -- including getting him mauled by a lion and bludgeoning him with a sledgehammer while he's still conscious.
138** There was also a one-shot (well, technically, ''two''-shot) character employed at the power plant in "Marge Gets A Job." This guy was shown polishing a shotgun and talking to himself:
139-->'''Crazy Dude:''' I am [[NamesToRunAwayFromReallyFast the Angel of Death]]. The time of purification is at hand.
140** [[Characters/TheSimpsonsHomerSimpson Homer Simpson]] himself went on a murderous rampage in a "Treehouse of Horror" episode when the cable wasn't working and when they ran out of beer in a WholePlotReference to ''Film/TheShining''.
141--->'''Homer:''' Well, what do you think, Marge? All I need is a title. I was thinking along the lines of "No TV and no beer make Homer go... something, something."
142--->'''Marge:''' Go crazy?
143--->'''Homer:''' '''DON'T MIND IF I DO!!!!''' ''(and proceeds to, well, go crazy)''
144** [[SadistTeacher Jack Lassen]], Bart's substitute teacher from "Blazed and Confused", is a mentally unstable individual who burns a match on his eye, cuts himself with a knife just below his eye to scar himself, shaves Bart for attempting to pull a prank, electrocutes him, breaks things when angered, and finally tries to murder Bart for ruining his stint as the ignis for Blazing Guy. After getting fired from Springfield Elementary and getting a job at the penitentiary, he bonds with Sideshow Bob over their mutual murderous hatred of Bart.
145* ''WesternAnimation/SkullIsland2023'': The [[Characters/MonsterVerseSkullIslandKaijuAndOtherCreatures Kraken]], the main antagonist of the first season, is [[ItCanThink intelligent]] but it also has a {{sadist}}ic and murderous streak that's second only to [[Characters/MonsterVerseKingGhidorah King Ghidorah]] if anyone. It attacks and tears apart the cast's boat for no reason, using its CombatTentacles to fling around, tease and toy with its victims. It's also revealed that the Kraken tries to goad [[Characters/MonsterVerseKingKong Kong]] into fighting it to the death for supremacy over Skull Island by grabbing innocent whales out of the ocean and throwing them at Kong's lair, [[spoiler:and that when it first awoke, it almost gleefully massacred an entire village that was under Kong's protection, telling leaving the bodies lying uneaten where they were slain for Kong to find before the Kraken taunted him]]. Pretty much the only thing that makes this creature less psychotic than the aforementioned Ghidorah is that it seems solely interested in taking over Skull Island, compared to Ghidorah's active interest in conquering the whole planet.
146* Replicon, the most {{sadist}}ic, trigger-happy villain in ''WesternAnimation/SkysurferStrikeForce''.
147* ''WesternAnimation/SouthPark'', being a BlackComedy, is a series full of Ax Crazies.
148** [[Characters/SouthParkEricCartman Eric Cartman]]. He [[spoiler:kills Scott Tenorman's parents and feeds them to him in the form of chili. Why? [[DisproportionateRetribution/SouthPark Because Scott scammed him out of $16.]]]] On his page on the official [[http://southpark.wikia.com/wiki/Eric_Cartman#Mental_Health South Park wiki]], it has a detailed paragraph on his mental health. Apparently, Eric Cartman shows signs of [[{{Sadist}} sadism]], Schizophrenia, identity issues, gender confusion, psychosis, psychopathic nature, [[{{Narcissist}} narcissism]], and [[DepartmentOfRedundancyDepartment possibly even insanity]].
149** In addition to Cartman, there is a good cast of violent, crazy characters: Saddam Hussein, the Earth Day Brainwashing Society, the Woodland Critters and WesternAnimation/MickeyMouse. But '''Mel Gibson''' (in the canon of the series of course) is the best one.
150** Sheila Broflovski, who was already crazy to begin with, was upgraded to this in ''WesternAnimation/SouthParkBiggerLongerAndUncut''.
151%% ** Randy Marsh, especially in "T.M.I." and "A Nightmare on Facetime".
152** "Hell On Earth 2006" shows the "antics" of Ted Bundy, John Wayne Gacy and Jeffery Dahmer, RealLife {{Serial Killer}}s. Said "antics" are called so because they become a parody of sorts of ''Film/TheThreeStooges'' after their initial introduction.
153** The obviously insane Hat [=McCullough=] from "Free Hat", though his defenders claim he killed [[WouldHurtAChild those twenty-three babies]] in self-defense.
154** Trent Boyett from "Pre-School". After he gets released from juvenile hall, he puts Butters and the sixth-graders in the hospital, the former for not coming to his defense when he was being arrested.
155* ''WesternAnimation/SpongeBobSquarePants'':
156** [[Characters/SpongeBobSquarePantsMrKrabs Mr. Krabs]] is often a step away from being dangerously insane because of his extreme obsession with money. "Clams", for instance, has [=SpongeBob=] and Squidward rightly disturbed from seeing him go crazy over Ol' Bluelips stealing his millionth dollar. This is even more prominent after the movie.
157*** Mr. Krabs in "Squeaky Boots" after [=SpongeBob=]'s boots are hidden under the floorboards of the Krusty Krab, and he keeps hearing the squeaking sounds everywhere he looks.
158** Mrs. Puff turned into this when she tried to ''murder'' [=SpongeBob=] in "Demolition Doofus"; when he did not get hurt in the demolition derby due to his NighInvulnerability and bad driving and became a star instead, she's ''livid'' and tried to do it herself. And she does not get arrested for it. [[{{Bowdlerise}} Toned down in the book release]] where she instead enters him in the derby in hopes he'll get badly injured to the point he'll never drive again.
159** [[Characters/SpongeBobSquarePantsSheldonPlankton Sheldon Plankton]] himself became this in [[WesternAnimation/TheSpongeBobSquarePantsMovie the first movie]]. He is much more deranged, {{sadist}}ic, depraved and homicidal than usual.
160** In "Nature Pants", [[Characters/SpongeBobSquarePantsPatrickStar Patrick Star]], of all people, goes crazy when [=SpongeBob=] refuses to come home. He even threatens to put [=SpongeBob=] in a jar and keep him in there. Forever.
161** [[Characters/SpongeBobSquarePantsTitularCharacter SpongeBob]] himself becomes one in "Bummer Vacation" when he thinks Mr. Krabs is only putting him on vacation to replace him with Patrick, prompting him to strangle him and take his place.
162* A good portion of ''WesternAnimation/{{Superjail}}'''s cast. ''Especially'' [[KillerRobot Jailbot]].
163* [[Comicbook/TeenageMutantNinjaTurtlesMirage The Mirage Turtles]] in {{the|Movie}} ''WesternAnimation/{{Teenage Mutant Ninja Turtles|2003}}'' [[TheMovie TV movie]] ''WesternAnimation/TurtlesForever''.
164%% ** [[BigBad Shredder]] himself in the [[WesternAnimation/TeenageMutantNinjaTurtles2003 2003 series]].
165* In ''WesternAnimation/TheTick'', [[CardCarryingVillain The Evil Midnight Bomber What Bombs at Midnight]] is as crazy as they come, not even being able to get through a full sentence before going into another rant. As a result, he's one of the best-known and memetic characters from the show despite being a OneShotCharacter.
166* ''WesternAnimation/{{Thundercats 2011}}'' has Kaynar, a {{giggling|Villain}} PsychoForHire recruited as one of BigBad Mumm-Ra's new [[FourStarBadass generals]]... when they bust him out of ''prison''. His EstablishingCharacterMoment sees him strapped to a gurney and heavily restrained just to be moved to solitary confinement, which he earned after killing [[SerialKiller eleven inmates]]. He's pretty sanguine about his punishment:
167--> '''Kaynar:''' At least I'll have the voices in my head to talk to.
168* ''WesternAnimation/TotalDrama'':
169%% ** Eva and Izzy. Izzy does appear as a lovable goofball but she shows signs of this.
170** [[Characters/TotalDramaDuncan Duncan]] loves to stab things, blow stuff up, burn things, you name it. But the one which takes the cake has to be when he blows up Chris's mansion and runs from it laughing, [[CardCarryingVillain just to prove how evil he is]].
171-->'''Duncan:''' ''[[StabTheSalad (gleefully stabbing a bunch of bananas with his knife)]]'' Die! Die! Die!
172** Mal, the evil personality of Mike, of the second generation. He just [[{{Sadist}} loves inflicting pain on others]].
173** Scarlet's true self is this. To the extent where she tried to [[spoiler:blow up the island, which would have killed everyone]].
174** [[Characters/TotalDramaCourtney Courtney]] is a more subtle version. While she starts out just a little uptight and arrogant, her unfair elimination in ''Island'' seems to have done a number on her sanity and from then on she seems to be [[HairTriggerTemper extremely quick to resort to violence at the slightest inconvenience]], and so obsessive that it comes across as somewhat divorced from reality. Heather even points out that she's become as unstable as Izzy following [[spoiler: Courtney's boyfriend Duncan cheating on her with Gwen.]]
175* Josse, of the Ice Dancers from ''WesternAnimation/TotalDramaPresentsTheRidonculousRace'', is this. Aside from throwing temper tantrum just about every time she and her partner Jaques aren't in 1st place, she has no qualms about hurting people, even if the person in question is her ''own partner''.
176* [[BigBad Galvatron]] from ''Franchise/TheTransformers'' was so violently nuts, ''the AlwaysChaoticEvil Decepticons actually took him into therapy''. Naturally, he blew up the [[PlanetOfHats therapy planet]].
177--> '''Therapist''': Just say whatever comes to mind.
178--> '''Galvatron''': Kill! Smash! Destroy!
179--> '''Therapist''': Continue.
180--> '''Galvatron''': Rend! Mangle! ''[[ArsonMurderAndJaywalking Distort]]''!
181* From ''WesternAnimation/TheVentureBros'', Tim-Tom and Kevin, Dr. Girlfriend/Mrs. Monarch's aptly named Murderous Moppets, who [[PsychoKnifeNut like knives]] a little too much.
182%%** Also Brock Samson in his worst moments.
