History SerialKiller / WesternAnimation

* [[AxCrazy Flippy]] from ''WebAnimation/HappyTreeFriends''.

* The ''{{WesternAnimation/Disenchantment}}'' episode "Faster, Princess! Kill! Kill!" features the [[PublicDomainCharacter fairy-tale siblings]] Literature/HanselAndGretel, and [[AdaptationalVillainy reimagines them]] as a [[SiblingsInCrime pair of]] murderous {{cannibal}}s who [[InvitedAsDinner lure unsuspecting travelers]] to their {{gingerbread house}} in order to kill and eat them. They hide the butchered remains of their victims in [[CannibalLarder their basement]] to later process them into food.

''Film/RedDragon'' film, with a few other tropes thrown in.

* ''WesternAnimation/SouthPark'' has (at least) four episodes involving serial killers.
** "Cartman's Incredible Gift" features the Left-Hand Killer, who is a better example of a typical serial killer in comparison to later examples, though not by much. He's mostly a parody of Francis Dolorhyde as depicted in the newer

** "Cartman's Incredible Gift" features the Left-Hand Killer, who is a better example of a typical serial killer in comparison to later examples, though not by much. He's mostly a parody of Francis Dolorhyde as depicted in the newer ''Film/RedDragon'' film, with a few other tropes thrown in.
** "Hell On Earth 2006" shows the "antics," of Ted Bundy, John Wayne Gacy and Jeffery Dahmer. Said "antics," are called so because they become a parody of sorts of Film/TheThreeStooges after their initial introduction.
** The [[AxCrazy obviously insane]] Hat [=McCullough=] from "Free Hat", though his defenders claim he killed those twenty-three babies in self-defense.

* ''WesternAnimation/Ben10Omniverse'' villain Khyber is an EgomaniacHunter whose trophies include the skulls of sapient aliens. His current target is Ben.
* ''WesternAnimation/TheOwlHouse'': Amazingly [[Characters/TheOwlHouseEmperorBelos Philip Wittebane]] actually predates the term by a little over two centuries and seems to be one of the most prolific ones ever even though he doesn't get his hands dirty himself, preferring to let the inherent danger of the Isles do the work for him. Philip's need for Palismen to extend his life has lead him into leading the denizens of the Boiling Isles into dangerous situations that benefit his plans and stealing their Palismen after their owners are deceased, akin to a trophy of his victims. Him doing the exact same thing to Luz and Lilith, despite neither of them having a Palisman on them at the time, shows that he's become used to [[MurderIsTheBestSolution using such tactics]] to resolve his problems, even when there's no real need for it. His lair filled with his personal belongings has ''piles'' of broken palismen scattered about them, which Philip hoards to have one on hand whenever he needs it, showing that Philip has been responsible for a ''lot'' of missing people over the years, many of whom seemed friendly and helpful based on Luz' interactions with them.
** It becomes worse with the revelation that Philip is Emperor Belos. Since ClonesArePeopleToo, Belos' ''modus operandi'' of creating, killing, and hiding the bodies of countless Grimwalkers as ReplacementGoldfish to his deceased brother, whom he also killed in rage for "betraying" him (implied to be for marrying a witch), this is not so different from how some serial killers create a pattern of seeking out people who remind them of someone they were close to or feel wronged by, and end up killing them. The Collector even accuses him of creating so many grimwalkers just to destroy them, and accuses him of ''enjoying'' it. Belos denies this, [[BeneathTheMask but with a smirk on his face]].

* The ''WesternAnimation/TotalDrama'' episode 'Hook, Line, and Screamer,' dealt with this: the contestants had to watch a horror movie about a [[OverlyLongGag psycho killer with a chainsaw and a hook]] (the whole thing said every time.) As quoted above, Duncan found it hilarious, until [[spoiler:a real killer confronts Gwen, and everyone rushes to save her. Thankfully, she manages to kick his butt.]]

** [[BigCreepyCrawlies Shwick]] is implied to have lured many people to their deaths by taking them to an underground "rehearsal room" beneath his apartment in New York City, and then [[FedToTheBeast feeding them to an unseen monster]] living behind a mousehole. He even threatens Courage into complying with his requests by pointing to a pile of bones and saying, "You ''do not'' want to see what made these bones!".

* In ''WesternAnimation/BatmanBeyond'' it is [[ImpliedTrope Implied]] that villain Patrick "Ratboy" Poundstone is one. With the reveal that Dana was not the first person he kidnapped and his comment on how the other don’t laugh at him anymore, it is clear what happened to the previous people that he kidnapped.

* ''WesternAnimation/CourageTheCowardlyDog:''
** In his first appearance, Katz ran a HellHotel where he fed his guests to spiders for no discernible reason other than to just do it -- yet another horrifying trope this show played straight and seriously.
** In his second appearance, he turned his victims into machines to have them battle to the death for his amusement. He also tried to blow up a submarine with all aboard and, despite having a motive this time, still relished in killing a huge number of people. His only appearence where what he's doing isn't a front for commiting murders is his candy shop. Then again, he seemed to [[FridgeHorror be well versed in]] [[HumanResources turning people into candy]]...
** Benton Tarantella and Eroll von Volkheim. "Amatuer film directors" who managed to slay 12 people before their deaths. Then they came back from the dead to keep doing it!
** An example of a supernatural one is the Great Fusili who tricks people and transforms them into puppets for him to play.
** Shwick is implied to have lured many people to their deaths by taking them to an underground "rehearsal room" and feeding them to a monster living in a mousehole.
