History AxCrazy / WesternAnimation

** Uncle Ruckus at his absolute worst.

** All three members of [[TerribleTrio the Hateocracy.]]

* Cat from ''WesternAnimation/CatDog'', in the episode "Monster Truck Folly". Although it could also count as a CrazyAwesome.

** Nicole Watterson. Several episodes have shown that she can become dangerously insane and ''even'' homcidal.

** Nicole Watterson herself has her moments, especially in "The Limit".

** [[BigBad Katz]], as expected from a [[{{sadist}} sadistic]], psychopathic SerialKiller. His first appearance had him feeding the residents of his hotel to spiders, and to remind you ''this is his first appearance''.

** Mr. Krabs is often a step away from this because of his extreme obsession with the money. Watch the episode "Clams".
** The Tattletale Strangler as well.

* ''WesternAnimation/SpongeBobSquarePants''

** Patrick, in "Valentine's Day".
** Dennis from TheMovie.

** Mrs. Puff turned into this when she tried to ''murder'' Spongebob!!

** A [[ https://www.youtube.com/watch?v=xwEXtSCKkTM cutaway gag]] shows [[UsefulNotes/Davy Crockett]] was like this.

** Bill Cipher is this in spades.

** [[BigBad Aku]] is a sadistic demon who kills and tortures [[ForTheEvulz just 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.

** [[AbusiveParents The High Priestess]] from [[DarkerAndEdgier Season 5]] is one of the most horrifyingly insane villains to ever grace a western animated series. '''[[EstablishingCharacterMoment HER FIRST ACTION]]''' is putting her 7 daughters through absolutely monstrous training that can't even be called TrainingFromHell, all to kill Jack. She does this ''the moment after they're born'', and never lets them stop for even a second, having her henchmen viciously assault/torture them if they do [[spoiler: (Just ask poor [[JerkassWoobie Ashi]])]]. We truly see how utterly fucked up she is, however, when she [[spoiler: kicks her daughters into a vat of hot, liquefied coal - ''NAKED'' - as a sick, twisted ritual to appease their god, Aku. It's '''agonizing'''.]] Later on, when [[spoiler: Ashi [[BecauseYouWereNicetoMe refuses to kill Jack]], she flips out and tries to kill her herself.]] And you thought [[Anime/KillLaKill Ragyo]] was a shitty mother?

** In addition to Cartman, there is a good cast of antagonists which undoubtedly belong to this trope: Saddam Hussein, the Earth Day Brainwashing Society, the Woodland Critters and MickeyMouse. But '''Mel Gibson''' (in the canon of the series of course) is the best one.

** [[BigBad Aku]] is a sadistic {{demon}} who kills and tortures [[ForTheEvulz just 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.

* Aku from ''WesternAnimation/SamuraiJack'' was always a sadistic, extremely homicidal creature, but 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.

* The [[EraSpecificPersonality early version]] of WesternAnimation/DaffyDuck was usually a fairly [[CloudCuckoolander harmless nutcase]], but in "The Daffy Doc" 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.

** Then we have Magic Man, [[PsychoForHire Me-Mow]] and Ricardio.

** The Lich. He's an OmnicidalManiac with a [[{{sadist}} sadistic]] streak, after all.

** He is impulsive, psychotic, irrational and violent in the most frightening way possible when he is in a bad mood, [[spoiler:and has even committed cannibalism.]]

** The original Earl of Lemongrab is the '''living''' embodiment of this trope. Impulsive, psychotic, irrational and violent when he is in a bad mood, and [[spoiler: has even committed cannibalism.]]

* ''WesternAnimation/CourageTheCowardlyDog''
** [[SerialKiller Katz]]. Just check out some of his killing methods, and [[SlasherSmile smiles.]]

--> ''"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."''

* ''WesternAnimation/TheSimpsons'':

* Disney's classic ''Mickey and the Beanstalk'' 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. See it [[http://www.youtube.com/watch?v=mGnz4RykgF8 here]].
