Serial Killer / Western Animation

• American Dad!
  • In a Halloween Episode, Stan, in order to upstage his neighbor's awesome haunted house, brings in five of the most vicious serial killers in the Eastern Seaboard to act as attractions in his own. Havoc predictably ensues.
    Stan: "Head for the woods, its always safe there!"
  • In the same episode, Klaus claims that after university he traveled around Italy, stabbing students.
• In Batman Beyond, it is implied that one-shot villain Patrick "Ratboy" Poundstone is one. With the reveal that Dana was not the first person whom he kidnapped, and his comment on how "the others" don't laugh at him anymore, it is clear what happened to the previous people that he kidnapped (with the implication that his victims were fed to his pet giant rats).
• Beavis And Butthead:
  • A couple of episodes dealt with serial killers. In "Most Wanted" the duo hunt for a serial killer with a tattoo on his forehead of the word "KILLER" whom we later find out is named Tom, so they can collect the prize money. They end up encountering him in their backyard and he attempts to kill them but due to their stupidity they think he is also looking for the killer. He becomes friends with them because Beavis is just as crazy as he is and as a reward he gives them tattoos of butts on their butts, we see him in a later episode calling a dating service to invite women over to his jail cell so he can kill them.
  • Another episode "A Great Day" they encounter another serial killer whom resembles real life killer Jeffrey Dahmer after following a trail of blood to his house he gives them 20 bucks to forget what they saw, later on he can be seen loading a dead body into the trunk of his car and the duo present him with the body of a canary presumably belonging to the victim that had been stabbed to death he again tells them to forget what they saw and gives them another 20 bucks.
  • The crazy old farmer from the episode "Cow Tippin'" is probably one, considering how he decides to chop up a cow that fell on Beavis with a chainsaw while muttering "The Lord giveth and the Lord taketh away..."
• Ben 10: Omniverse villain Khyber is an Egomaniac Hunter whose trophies include the skulls of sapient aliens. His current target is Ben.
• Courage the Cowardly Dog:
  • Katz, the most recurring (and evil) villain in the series, is definitely one of these. In each of his appearances, Katz opens a shady business of some sort (i.e. a motel, luxury resort, candy factory, submarine cruise, etc.) which is ultimately just a front for luring in his customers to their deaths.
  • Benton Tarantella and Eroll von Volkheim. Posing as a duo of independent filmmakers, they managed to slay 12 people in order to record their gruesome deaths as movies, before they were arrested and eventually died. But then they both came back from the dead just to continue their old hobby!
  • An example of a supernatural killer is the Great Fusili, who tricks people into joining his traveling entertainment troupe so that he can transform them into lifeless puppets for him to play with.
  • Schwick 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 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!".
• The Disenchantment episode "Faster, Princess! Kill! Kill!" features the fairy-tale siblings Hansel and Gretel, and reimagines them as a pair of murderous cannibals who lure unsuspecting travelers to their gingerbread house in order to kill and eat them. They hide the butchered remains of their victims in their basement to later process them into food.
• Family Guy:
  • An episode dealt with the "Fat Guy Strangler", who strangled fat men. It turns out to be Lois' brother Patrick (voiced by Robert Downey Jr.), who was sent to an insane asylum as a child after being traumatized by seeing Jackie Gleason having sex with his mother, and from there concluded that all fat people were evil and so went on a killing spree.
  • An earlier episode had The Mass Media Murderer, who specifically targeted members of the press. Another episode briefly featured a Quahog encyclopedia of crime, which mentioned such figures as "The Berserk Hobo" and "The Golden Autumn Day Strangler".
  • Stewie has killed many people over the course of the series.
• Happy Tree Friends: Flippy's evil Split Personality, Fliqpy, is a murderous psychopath who goes out of his way to kill anyone he sees.
• On Jimmy Two-Shoes, this was Heloise's original characterization, before they decided to make her a Mad Scientist instead. She's still pretty Ax-Crazy.
• Hazbin Hotel: Alastor was a serial killer in life. When he arrived in Hell he acted like one towards Overlords, abducting them and apparently torturing them over the radio.
• A Looney Tunes short entitled "Bye Bye Bluebeard" involved Porky Pig being paranoid about a serial killer named Bluebeard who raids houses to kill the residents and steal their food, a mouse hearing the news decides to impersonate him eventually Porky sees through his disguise and soon comes face to face with the real Bluebeard.
• The Owl House: Amazingly 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 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 Clones Are People, Too, Belos' modus operandi of creating, killing, and hiding the bodies of countless Grimwalkers as Replacement Goldfish 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, but with a smirk on his face.
• South Park 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 Red Dragon 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 The Three Stooges after their initial introduction.
  • The obviously insane Hat McCullough from "Free Hat", though his defenders claim he killed those twenty-three babies in self-defense.
  • "Merry Christmas Charlie Manson".
• The Tattletale Strangler from SpongeBob SquarePants.
• The Total Drama episode 'Hook, Line, and Screamer,' dealt with this: the contestants had to watch a horror movie about a psycho killer with a chainsaw and a hook (the whole thing said every time), and then have to endure Chef dressing as said killer and acting like him. As quoted above, Duncan found it hilarious, until a real killer confronts Gwen, and everyone rushes to save her. Thankfully, she manages to kick his butt.
