[[folder: Notable Protagonists]]
!!'''Amanda and Josh Benson'''

The protagonists of "Welcome to Dead House" and the very first protagonists of the series. Amanda and her younger brother Josh move to the town of Dark Falls after their father inherits a house from a dead uncle. While Josh is adamant about refusing to go along with the plans to move, Amanda tries to keep an open mind about the situation, until she learns her new home has a terrible secret.

* AnnoyingYoungerSibling: Josh, but only slightly.
* BadassNormal: [[spoiler: Josh, at one point, attempts to bash Mr. Dawes' head in when he realizes that he's not alive.]]
* EarlyInstallmentWeirdness: It's hard to imagine that Amanda and Josh are protagonists in a ''{{Goosebumps}}'' book due to the fact that neither of them have any of the {{Flanderization}} traits prominent in the other protagonists, especially those with younger siblings. Amanda isn't a StrawLoser who is TheUnfavorite to her AnnoyingYoungerSibling, nor is Josh a raging SpoiledBrat doted on by their parents. This makes more sense when considering that they were the very first protagonists and actually set the mold for the characters to come.
* FoolishSiblingResponsibleSibling: Josh is the foolish to Amanda's responsible. Josh is more self-absorbed and less willing to go along with their family's move, while Amanda, who has her own reservations about moving, recognizes that arguing about it is just going to cause tension.
* KidHero: [[spoiler: It falls upon both Benson siblings to rescue their parents after they are taken captive by the Dark Falls residents, and in doing so, they end up killing most of the townspeople... except Mr. Dawes.]]
* OnlySaneMan: Amanda. Even though she admits she sometimes lets her imagination get the best of her, she proves to be the more levelheaded member of her family due to how she manages to not succumb to the stress brought on by moving to a new house, while her brother refuses to cooperate and her parents start getting on each other's nerves.
* PsychicDreamsForEveryone: Her first night in Dark Falls, Amanda has a nightmare about her family as living skeletons devouring human bones. [[spoiler: Which is almost exactly what would've happened to the Bensons if the people of Dark Falls had succeeded in draining their blood.]]
* SpoiledBrat: Josh. Amanda and their parents acknowledge that he's slightly spoiled, but unlike the other spoiled siblings seen in the later books, Mr. and Mrs. Benson do little to encourage it.
* StrawLoser: Averted. Neither Benson sibling come close to the levels of StrawLoser some of the other protagonists share. Amanda mentions that she can be kind of klutzy when it comes to playing softball, but it's not something PlayedForLaughs or PlayedForDrama.

!!'''Billy Deep'''

The protagonist of "Deep Trouble." Billy is a budding undersea explorer on vacation with his uncle, Dr. Deep, and his sister, Sheena. On the trip, he encounters a mermaid who he saves from kidnappers, and later goes on to have many more undersea adventures.

* {{Adorkable}}: His constant optimism and awkward attempts at befriending the mermaid definitely fall under this.
* AsianAndNerdy: According to the Horrorland spinoffs, he's asian american.
* BadassAdorable: Well, "Badass" would be a stretch, but he can still be pretty brave when push comes to shove.
* TheAtoner: He spends the second half of "Deep Trouble" trying to make up for getting the Mermaid captured.
* BadassFamily: He, his sister, and uncle deal with sea based threats on a regular basis.
%%* BigBrotherInstinct: Toward Sheena.
* BreakTheCutie: Doesn't last long, though.
* CharacterDevelopment: He's introduced as an arrogant, hot-headed glory hound, but by the end of the book, he's a much more selfless individual, willing to risk his life to save his new friend.
* CheerfulChild: Oh,yes. This is what sets him apart from [[StrawLoser his predecessors.]]
* CrouchingMoronHiddenBadass: By "Creep from the Deep", he's definitely earned this title.
* CloudCuckooLander: In the book's first few paragraphs, he criticizes Sheena for not opening her mind to concepts like the Easter Bunny and Santa Claus.
* FriendToAllLivingThings: He makes fast friends with the mermaid, and claims that when he's a famous undersea explorer, he's going to give the creatures he encounters pet names. H also shows remorse about feeding a school of guppies to Dr. D's pet eel.
* FearlessFool: Not entirely fearless, but when his uncle warns him about sharks in the reef, he replies, "Sharks! Wow!" Later on, he rushes headfirst into a gang of thugs trying to kidnap the mermaid.
* HotBlooded: See above.
* NiceJobBreakingItHero: Thanks to him: the benevolent Mermaid was captured.
* StrawLoser: Averted. Billy avoids most of the characteristics that the other protagonists have.

!!'''Carly-Beth Caldwell'''

The main character of ''The Haunted Mask'', a tormented and meek young woman who acquires a cursed Halloween mask which attempts to take over and turn her into a destructive monster.

%%* BeCarefulWhatYouWishFor
* ButtMonkey: She grows out of it.
* TheBusCameBack: She's the only protagonist confirmed to appear in the upcoming movie. Unfortunately, it's as the mask's host.
* EvilFeelsGood: After putting on the mask and preparing for sweet revenge.
* [[OnlySaneMan Only Sane Girl]]: In the Horrorland series, she soon becomes the most levelheaded member of the group.
%%* ShrinkingViolet
* ThresholdGuardian: In ''Scream Of The Haunted Mask'', she hides the mask in her basement to keep it from menacing anyone else.
* TookALevelInBadass: Grows much more brave and tough from the Halloween she spent with the mask.

!!'''Evan, Andy, and Trigger'''

The main characters of ''Monster Blood.''

* BerserkButton: Andy ''hates'' to be called by her real name, Andrea.
%%* BigFriendlyDog: Trigger
%%* ButtMonkey: Evan.
%%* PluckyGirl: Andy.
%%* RedHeadedHero: Evan.
* StrawLoser: Evan is one of, if not ''the'', biggest one in the whole series. He can ''not'' catch a break.
** ''Monster Blood II'' ends with Evan now permanently taking care of Cuddles even though he hates him (with the implication that Cuddles ate more Monster Blood), ''III'' ends with Evan shrunken down to a few inches, and ''IV'' ends with him facing a horde of angry Conan clones.
* TooDumbToLive: Evan frequently tries to use Monster Blood to avenge himself on his tormentors, such as Conan, Kermit, and one of his teachers, even though he has firsthand knowledge that these attempts will not work and he just makes things worse for himself.

!!'''Greg Banks'''

The main protagonist of ''Say Cheese and Die!'' and its sequel. Greg has the unfortunate luck of finding a camera that causes bad things to happen whenever it takes a picture of someone, such as two of his friends being injured, his father almost dying in a car accident, and one friend disappearing completely.

* BodyHorror: Besides the camera making him obese, it also causes him to develop a horrible skin rash that makes him look like a lizard.
* ButtMonkey: More so in ''Say Cheese And Die - Again!'' due to Mr. Saur's treatment of him and what the camera does to him.
* CassandraTruth: His friends don't think there's anything evil about the camera despite mounting evidence that it is taking pictures of things that haven't happened yet. Greg only keeps using it in the first book because they keep pressuring him to do it. In the second book, his report on what happened with the camera is given an "F" and because that jeopardizes Greg's plans for the summer, he thought finding the camera was the only way to have his grade fixed.
* OnlySaneMan: Greg is considered the sensible one in his group of friends, and he doesn't like it because they tease him for it.
* RevengeBeforeReason: He becomes insistent on snapping a picture of Mr. Saur to get back at him for his bad grade and for the way he's treated him. [[spoiler: And then the book ends with Mr. Saur taking a picture of ''the whole class'', but it's left ambiguous as to what happened.]]
* ThrowTheDogABone: [[spoiler: The ending of the TV adaption of ''Say Cheese And Die - Again!'' has Mr. Saur lose all his hair after his picture is taken, which can be considered LaserGuidedKarma for his treatment of Greg.]]
* TookALevelInDumbass: By ''Say Cheese And Die - Again!'' Greg has become ''much'' less sensible. He made the mistake of writing an essay about what happened with the evil camera, and when he got a bad grade for it, decided the only course of action was to find the camera again as proof.
* WeightWoe: In ''Say Cheese and Die - Again!'' the camera causes Greg to rapidly gain weight. At first, he's mercilessly teased by the other kids for being fat, but when he shows up for school the next day twice as big as before, his classmates no longer think it's funny and feel bad for him. [[SadistTeacher Mr. Saur]], on the other hand, does nothing but mock him.
* WhatHappenedToTheMouse: He doesn't return for ''Say Cheese and Die Screaming!'' Mostly because the evil camera somehow ended up in the possession of another family before it ends up with Julie. But we're never told what happened to Greg or how the camera wound up with someone else. [[spoiler: The implications behind this are not helped by the AmbiguousEnding to ''Say Cheese And Die - Again!'']]

!!'''Lizzy and Luke Morris'''

The main characters of ''One Day In Horrorland''

%%* AnnoyingYoungerSibling: Luke.
* CassandraTruth: [[spoiler: Most of the Very Special Guests are not entirely trustworthy of the Morris siblings because they think they might be spies for the Horrors. It turns out however that of course Lizzy and Luke are the trustworthy ones. The twins Jillian and Jackson were unwittingly acting as TheMole for the Menace and attempted to make the Morrises as TheScapegoat. Lizzie realizes they've been trying to fool everyone when she catches Jillian lying.]]
* FoolishSiblingResponsibleSibling: Luke's the foolish one, Lizzy's the responsible one.
* [[TheLeader The Leaders]]: Of the Very Special Guests in the last two books in the Horrorland series, due to their prior knowledge of the theme park.
* OlderAndWiser: Although they're only a year older in the [=HorrorLand=] series, they return to Horrorland to help out the rest of the kids escape.
* TooDumbToLive: Luke has shades of this in ''Return to Horrorland'' since he seems too eager to try out the rides at Horrorland despite the fact that he knows they are potentially lethal and that the Horrors tried to kill him and his family the last time they were there.
[[/folder]]

[[folder: Villains and Monsters]]
!!Andrew Craw/The Headless Ghost
* AndIMustScream: Being made to wander his childhood home for ''years'' while unable to see, smell, hear or taste anything must've absolutely sucked.
* AssholeVictim: In his backstory, he abused animals and played tricks on his servants until [[LaserGuidedKarma karma caught up to him]] in the form of the sea captain's ghost pulling off his head and hiding it.
** Than again, [[DisproportionateRetribution this was ''far'' more than he deserved.]]
* DeathEqualsRedemption: As his appearance in the end would suggest, it seems this horrifying fate made him into a much kinder person.
* GoOutWithASmile: After the kids find his head, he peacefully thanks them before fading into the afterlife.
* SmallRoleBigImpact: He only makes a true appearance at the very end of the book, but it really says enough about his character.
* UngratefulBastard: He is one nasty kid in the TV episode, even after the protagonists find his head for him. The book is better about this.

!!The Beasts

A race of ferocious bear/possum hybrids who play a bizarre game with their victims to choose who gets eaten.
* AbsurdlyHighStakesGame: As Ginger says, they play for keeps.
* {{Badass}}: You'd pretty much have to be to play a game like this for a living.
* AlwaysChaoticEvil: Downplayed, since unlike the Horrors, they actually have some sense of honor.
* BearsAreBadNews: Ginger views [[IronicNurseryRhyme "the Teddy Bear's picnic"]] in a whole new light after this adventure.
* BlueAndOrangeMorality: Everything they do is determined by the rules of their strange game, which certainly doesn't help our confused protagonists.
* CalvinBall: They don't make up the rules per say, they just hardly define them.
* CannibalTribe: We can assume that based on the rules of the game, they eat each other when there are no humans available.
* ChildEater: Losers of the game get eaten, and they will ''not'' make exceptions for children. [[FridgeHorror One shouldn't think too much of who else stumbled upon this game...]]
* CloudCuckooland: The neck of the woods they live in is full of oddly-colored plants and MixAndMatchCritters. It may even be an EldritchLocation, based on Fleg's comment about a path that "leads back to your world".
* EvenEvilHasLovedOnes: It's never explicit, but they do seem to care for each other, since Spork is shown keeping watch over an infant beast in the middle of the dangerous game.
* EvenEvilHasStandards: The Beasts strictly follow the code of the game, and thus will give their victims another chance should the rules condone it.
* EyeScream: Gleeb's right eye is missing, leaving an empty socket, which [[Squick he has a habit of picking at several times through the story.]] Ginger remarks it's probably from an earlier fight, and that she'd hate to see the loser.
* GeniusBruiser: They're huge, tough monsters that also happen to be skilled with building booby traps and handling wild animals.
* MixAndMatchCritters: Giant blue bears with tails like badgers, and builds like gorillas.
* ProudWarriorRace: That play tag?
* PunchClockVillain: The beasts don't play this game out of malice, but because it's ingrained in their culture. Spork even admits it gets boring at times, which gives Ginger a chance to tag him.

!!Body Squeezers

Alien invaders who can take over human beings by hugging and then crawling into their bodies. They're the villain of the two-part ''Invasion of the Body Squeezers'' books, and also feature in a sequel published under the [=GYG=] banner. They come in two varieties, green and blue.

%%* AliensAreBastards
%%* AndThenJohnWasAZombie
%%* AssimilationPlot
* KillItWithWater: Jack thinks this is their weakness when two of his possessed friends refused to go in a pool. [[spoiler: Unfortunately, when Jack attacks them with water, it turns out they aren't bothered by water at all. At the time, they just didn't feel like swimming.]]
* LoadBearingBoss: [[spoiler: Defeating their leader kills the green Body Squeezers.]]
* MyBrainIsBig: Their leader is a giant brain.
* VerbalTic: The humans they control speak with a *[=tt=]* at regular intervals.

!!Chop Suey

From the short story ''What's Cooking?'' She was a cafeteria worker whose disgusting dishes caused a revolt from the students she served them to, and was fired after she attacked some kids with a meat cleaver. If her name's said three times while standing on your tip toes, it summons her back as a vengeful ghost.

* AxCrazy: Or rather, Cleaver Crazy.
* BerserkButton: Calling her "Chop Suey" or not eating her food.
* CompanionCube: Her beloved cleaver. It's rumored she died after accidentally falling onto it.
* EmbarrassingNickname: She got her nickname because her "Chinese Surprise" was consider the worst.
%%* {{Expy}}: Of BloodyMary.

%%* ImAHumanitarian
%%* LethalChef
* PunnyName: Sue Chopman's her actual name. When she's brought back, she calls herself "Aunt Sue."

%%* StoutStrength

!!Conan Barber

The resident bully and secondary antagonist for most of the ''Monster Blood'' series.

* TheBully: He loves tormenting Evan and getting him in trouble with their teacher.
* BigManOnCampus: Evan remarks that he looks 32, even though he's only 12.
* DirtyCoward: He's not so tough and badass when it comes to heights and [[AttackOfTheFiftyFootWhatever giant hamsters]].
* HiddenDepths: WordOfGod says that he sleeps with a teddy bear named Fluffster and gets a bedtime story every night.
* InSeriesNickname: "Conan the Barbarian", unsurprisingly.
* JerkJock: He actually ''slam dunks Evan through a basketball hoop'' in one part of ''Monster Blood II''.
* UngratefulBastard: Even after Evan saves him from getting eaten by Cuddles, he still bullies him at every opportunity.
* WhyDidItHaveToBeSnakes: He's afraid of heights.
* WouldntHitAGirl: Since [[EvenEvilHasStandards he doesn't hit girls]], he sticks Andy on a high tree branch instead after he beats up Evan.

!!Count Nightwing

The great grandfather of the Martinez family, Nightwing is a powerful vampire lord who derives his abilities from a mysterious substance called "Vampire Breath." Eventually, his grandson accidentally wakes him up from his centuries long slumber. Nightwing only wants to return to his own time, but is willing to involve children in his plans. Recently, he's been confirmed to appear in the 2015 movie.

* UngratefulBastard: When Freddie and Cara help him return to his time period, he repays them by refusing to help them get home and promising to turn them into vampires as soon as he finds his fangs.
* WeaksauceWeakness: He can't feed without his fangs, and he needs Vampire Breath to remind him where he left them.

!!The Creeps

An unpleasant group of lizard-creatures masquerading as human school bullies.

* AerithAndBob: Their names: Jared, Brenda, David...Wart?
* AliensAreBastards: We don't know just ''what'' they are, but they fit every other criteria.
* AndThenJohnWasAZombie:[[spoiler:The entire student body by the end of the book, including Ricky.]]
* AssimilationPlot: Creeps are created when special "identity seeds" are consumed by humans. The main four plan to disperse these seeds among the student body.
* TheBadGuyWins:[[spoiler:A rare example that benefits the protagonist.]]
* BlueAndOrangeMorality: Like most creatures in the series, the Creeps have very twisted and strange customs.
* ChildSoldiers: The main four, though it's unclear how old they are.
* EvilPhone: How they contact Ricky.
* KidsAreCruel: Their human guises. Rather unsurprising.
* TheLadette: Brenda, the only female, is no less ferocious than her comrades.
* LizardFolk: Huge, purple lizard/raptor kids. The cover makes them look oddly adorable.
* PetTheDog: Their loyalty toward Ricky, their supposed leader, seems surprisingly genuine. [[spoiler:At the very end, they give him the extra push to take revenge on the cruel student body as he's being mocked.]]
%%* SmurfettePrinciple: Brenda.

!!The Cuckoo Clock Of Doom

The titular machine from the book of the same name. It enters
the unhappy Webster home and changes things forever.

* AmbiguouslyEvil: It's never clear how sentient the clock is, but it does seem to single out Michael as it's subject.
* ArtifactOfDoom: For anyone foolish enough to fiddle with it, anyway.
* ButterflyOfDoom: Knocking off one of the years on it's calendar is enough to wipe out anyone born at the time.
* FeatheredFiend: The cuckoo bird, shown prominently on the cover. Turning it's head back triggers the clock's powers.
* MentalTimeTravel: Happens to anyone that twists the bird's head.

!!Cuddles the Hamster

[[SadistTeacher Mr. Murphy's]] pet hamster, who grows to enormous size and goes on a destructive rampage after eating Monster Blood.

* AttackOfThe50FootWhatever: The climax of the book.

* FatBastard: According to Evan - and that's ''before'' he grows to the size of a gorilla.
* RodentsOfUnusualSize: After he eats Monster Blood.
* [[WhatHappenedToTheMouse What Happened To The Hamster?]]: He supposedly eats more Monster Blood at the end of the second book, but although he's mentioned in subsequent books, we never find out what happened to him or if he became a giant again.

!!Dark Falls Residents

The undead inhabitants of a remote town who lure new residents there to eat them.

* AffablyEvil: You wouldn't be able to tell their true nature until it's too late.
* AntiVillain: They feast on living beings to sustain their town's existence.
* AlmightyJanitor: Compton Dawes, Dark Falls' mild mannered real estate agent, is not only a bloodsucking mutant, but he's also the most responsible for keeping the town alive.
%%* BitchInSheepsClothing
%%* CreepyChild: Obviously.
* AFateWorseThanDeath: Little Karen Somerset (and presumably other residents) thinks this way of her undead existence.
* AFeteWorseThanDeath: Their "welcoming ceremony" at the town Podium. This of course leads to AFateWorseThanDeath.
* HauntedHouse: Inverted. They inhabit every other home except the titular "dead house" where the living family stays.
* KarmaHoudini: [[spoiler: Compton Dawes survives the destruction of the other townspeople, and goes on to feed on more families.]]
* OurVampiresAreDifferent: They drink blood and are destroyed by sunlight like vampires, but bare more of a resemblance to ghosts or zombies.

* TheVirus: In their town, they'll welcome you as one of them-literally.
%%* UndeadChild
* UsedToBeASweetKid: Most of the children, probably.

!!Della Raver

Once a normal young girl staying at "Camp Cold Lake", Della grew tired of the constant safety rules and became homesick. She attempted to swim across the lake to leave camp, but she drowned. Now her lonely spirit roams the camp, desperate for a buddy to take her to the afterlife. [[spoiler: She actually tried to leave by going through the woods, but was bitten by a rattlesnake. She made Sarah Maas think she drowned as part of a ploy to lure her into the woods and kill her there.]]

* AntiVillain: A little girl who is willing to do anything to make a friend, even murder.
* AndIMustScream: Her ghost spent years wandering the camp, unable to leave the mortal plane.
* AxCrazy: Veers more and more into this after Sarah rejects her, even trying at one point to ''run her down with a motorboat.''
* BrokenBird: Being trapped for ''years'' in a place you hate and getting rejected by those you want as friends will really do that.
* CuteGhostGirl: When she's not trying to stalk and kill you, she's actually rather friendly, giving Sarah a coat when she was cold.
%%* CuteAndPsycho: See above.
* DespairEventHorizon: After Sarah makes her refusal clear, Della wails in misery and sinks into the ground.
* ManipulativeBitch: [[spoiler: Pulls off a vicious gambit where she makes Sarah terrified of the water by pretending to have drowned, so that she can find her when she least suspects it.]]
* IJustWantToHaveFriends: More specifically, she wants a "buddy" to join her in the afterlife.
* TragicVillain: Unlike many other antagonists, Della clearly resents being a monster and will do anything to escape it.
%%* UsedToBeASweetKid
* WoobieDestroyerOfWorlds: Arguably the most clear cut example in the entire franchise.
* {{Yandere}}: Brushing off her affections is a ''very'' bad idea.

!!Dr. Brewer

A botanist/father who spent hours in his basement trying to create new forms of plant life. These experiments caused him some...unsettling changes.

%%* AntiVillain: Brewer himself is a type V. [[spoiler:His clone is more a type II.]]
* TheAtoner: By the end of the book, he gives up his horrible experiments and tries hard to make up to his family. [[spoiler:Or so it seems.]]
* BodyHorror: His mutation into a plant creature. And lets not even talk about the the things he grows in the basement...
* CreepyBasement: His lab. The book is called "Stay Out Of the Basement" for a reason.
* CloningBlues: His clone held him hostage in a basement for weeks and tried to take over his life.
* DudeWheresMyRespect: To his boss for firing him.
%%* EvilutionaryBiologist
* EvenEvilHasLovedOnes: He loves his kids, Margaret and Casey, hence why he created his clones to be with them.
* FamilyUnfriendlyDeath: Disposes of his clone by chopping him in half. Even worse, he did it in full view of his children.
* FourEyesZeroSoul: Subverted. He's not really evil, just stubborn and willing to ignore certain morals.
* FromNobodyToNightmare: Played with. He doesn't become a super-villain like most instances of this trope, but his reckless experiments
turn him from a simple botanist to a MadScientist who endangers everyone around him.
* GeneticMemory: His clone went rogue because of this-since he was a near perfect copy of the original, he had all of that man's memories.
* HumanityEnsues: What made him think turning plants into humans was a ''good'' idea?
* KillAndReplace: His clone was presumably planning this, both for him and the rest of his family.
* LegoGenetics: Apparently,combining plant and human DNA only took him a few weeks.
* MadScientist: His freakish experiments with plant matter are what causes the book's conflict.
* {{Planimal}}: His entire time in the basement was spent creating these. Unlike most examples, these aren't cute or friendly in the slightest.
* NiceHat: An LA Dodgers cap, [[spoiler:which covers the leaves on his scalp.]]
* PlantPerson: [[spoiler:He spent hours in his basement trying to create these. Unfortunately for his family, he succeeded.]]
* TheWorkaholic: Spends hours in his basement trying to perfect his experiments and ends up sorely regretting it.

!!Emory Banyon
An award winning horror director and self-proclaimed King of Horror. While Emory is by no means murderous or evil, he's a self centered egotist and a terrible father, to the point that he is frequently trying to terrorize his son Jake into admitting he's scary. Emory is one of the realest villains in the entire franchise, due to the fact that, while there's nothing supernatural about him, he still antagonizes his son.

* AbusiveParents: One of the worst. [[spoiler: Though amazingly, Jake gets revenge twice over.]]
* BrokenAce: [[spoiler: Thanks to the pranks Jake pulls on him.]]
%%* ItsAllAboutMe
%%* NightmareFetishist
* ParentalNeglect: He'd rather think of Jake as a buddy then as a son, which seems to be his attempt to justify the torment he puts Jake through.
* ParentsAsPeople: He does care about Jake, but he's still a pretty horrible father.
* SmugSnake: He loves patronizing his son by giving him false reassurance that it's okay to admit he's scared.

!!Granny Deaver

From the ''Triple Header'' short story ''Ghost Granny''. Granny Deaver is a nasty old woman who sponged off a family she wasn't actually related to for three years. When she died, everyone had a hard time concealing their relief that she was gone. That relief was short lived when she returned as an evil spirit, intending to haunt her so-called family.

* EvilOldFolks: And she only became worse when she became a ghost.
* JabbaTableManners: She eats like a pig even as she complains about how bad the food is. Kelly and her brother once found Granny Deaver's teeth in the milk carton after she was done drinking it, and this grossed them out so much they stopped eating cereal completely.
* TheMillstone: To Kelly and her family, in life and especially in death. She makes their lives miserable by being rude, loud, and unpleasant, and they just can't get rid of her. Upon her return as a ghost, she ruins Kelly's birthday and scares away her friends, and spends the nights howling and wailing. It reached a point where a neighbor finally called the police thinking Kelly's family had a dog, but she scared them away.
* NoSenseOfPersonalSpace: She's always pinching Kelly and her brother when she's not barging into their rooms and leaving her stuff in their closets.
* ScrewPolitenessImASenior: She's domineering and has no sense of consideration or self-awareness towards how she behaves around others.
* SicklyGreenGlow: As a ghost.
* SuperpoweredEvilSide: She becomes animalistic when she gets truly angry, growing claws and fangs. [[spoiler: It's all for show. She can't actually hurt anyone and when Kelly realizes this, her mocking of Granny Deaver is enough to make her self destruct.]]
* TheThingThatWouldNotLeave: Kelly's parents let her stay with them because she has nowhere else to go, and they feel sorry for her. This only gets worse when she becomes a ghost.
* TookALevelInJerkass: Before she died, she was just rude. As a ghost, she terrorizes the family and anyone who enters the house. She claims that dying has brought her "evil side" out.
* UngratefulBastard: She complains about everything, alive or dead. She'll call the food Kelly's parents have made garbage but she'll eat it all and then steal from their plates.

!!The Greyworld Children

A terrifying clan of mutant children that reside in "Greyworld", a dimension rendered permanently gray. They roam the lonely streets, searching for unlucky visitors to convert to their clan. What's worse,they all used to be normal kids.

* AndIMustScream: Driven insane by years trapped in the Black and White world.
* AssimilationPlot: They desire nothing more but to rid anything-and anyone they see of color, turning them over to "the gray."
* CreepyChild: Holy shit. The "Oil spewing" ceremony speaks for itself.
* {{Cult}}: One composed of insane children. There's a reason this entry is considered one of the darkest in the series.
* MadnessMantra: "Turn. Turn to the Gray!"
* TragicMonster: Every one of these mutants were once perfectly normal schoolchildren who attended Bell Valley in 1947. Than the evil photographer Mister Chameleon sent them to Greyworld and it changed them forever.
* TrappedInAnotherWorld: For so long now they've given up hope of rescue.
* WeakenedByTheLight: The flee at the sight of any light or color. As it turns out, this weakens the fabric of the other dimension and allows an escape.

!!The Haunted Car

A possessed car purchased by Mitchell Moinian's father. The spirit possessing it is a young girl who died while she was taking the car for a joyride, and she now wants to kill Mitchell so she'll have someone to ride alongside her.

%%* AxCrazy
* CardCarryingVillain: She frequently professes that she's evil. [[spoiler: The shock of realizing she actually saved Mitchell from being burned alive when his house caught fire is so great it causes her spirit to be forcibly expelled from the car for good.]]
* EvilTwin: [[spoiler: The ghost is Marissa's twin sister, Becka.]]
* RedemptionEqualsDeath:[[spoiler: It's a rare unintentional example, but it's what prompts Mitchell to forgive her in the end.]]
* ImprobablyCoolCar: How it first appears.
%%* MyCarHatesMe
* NiceJobFixingItVillain: [[spoiler: When Becka took Mitchell on what would've been his death ride, she decides to kill him near his house to adhere to his wish of taking him home. When they get there, they discover Mitchell's house is in flames, and that by kidnapping him, Becka actually saved Mitchell from burning to death.]]
* UndeadChild: The spirit inside the car.

!!Haunted Mask

A living halloween mask, one of several created by a scientist.

* AscendedExtra: In the book ''The Haunted Mask II'', the Mask wasn't featured at all. In the television adaption, the Mask is added to the plot as the main villain, possessing the shopkeeper and turning Steve into his minion for the sake of getting to Carly Beth and possessing her again.
* BackFromTheDead: In the television adaption of ''The Haunted Mask II''.
%%* ClingyCostume
%%* ClingyMacguffin
* CreepyChild: Its hosts are always children, and it seems to possess a rather immature mentality. The version in TheMovie will be portrayed by an up and coming child actress.
* DemonicPossession: Happens gradually to its unlucky host.
* EvilCannotComprehendGood: The only way to remove it is with a "symbol of love."
* EvilIsPetty: Aside from gaining a proper host, it's only other goal seems to be terrifying others for respect.
%%* EvilMask
* FreudianExcuse: It was kept in a basement for years by its creator as a failed experiment, which probably led to it developing evil tendencies.
%%* GoneHorriblyWrong: Its origin story.
* GrandTheftMe: It does this slowly to Carly-Beth, and surprisingly quickly to the Shopkeeper. Judging by Carly's appearance in the movie, it seems it succeeded.
* IJustWantToBeLoved: Constantly looking for a host that will accept it.
* EvilIsHammy: Has plenty of moments of this in the second half of the episode ''The Haunted Mask II''.
* LatexPerfection: It's actually synthetic flesh.
%%* SealedEvilInACan
* TorturedMonster: It's mainly motivated by anger and self-loathing from being "unloved."
* WorthyOpponent: As of "Scream of the Haunted Mask", it seems to regard Carly-Beth as its favorite host.

!!Karl Knave

The sinister mayor of Karlsville from the three-part "Chillogy" episode.
* CanonForeigner: His story is completely exclusive to the TV series.
* CorruptPolitician: Subverted. He's officially the "mayor" of Karlsville and extremely evil, but he never actually does any politicking.
* {{Expy}}: Of SelfDemonstrating/TheJoker. Monstrous, malicious prankster in a bad purple suit who kills people by playing lethal games with them to amuse himself.
* ForTheEvulz: When Todd asks Karl why he's trying to [[AndIMustScream turn him into a lifeless doll]], Karl says that he just needed a hobby.
* ImAHumanitarian: He orders the townspeople to cook Jessica for him after he turns her into a pig girl.
* KarmaHoudini: [[spoiler:He escapes the destruction of Karlsville unharmed and can't believe his luck.]]

* ManipulativeBastard: He manipulates Jessica into pursuing her greed, then blames her for the flaw he himself set her up to pursue, and turns her into a pig.
* RealityWarper: In Karlsville his powers have almost no limits. He transforms Jessica into a pig girl, materializes minions out of thin air, and controls even the weather in the city. Fitting, since he's basically an evil ''WesternAnimation/LooneyTunes'' character.
* WouldHurtAChild: He only seems to target children, trying to kill one in every episode.

!! Keith

Antagonist of ''I Live In Your Basement''. A mysterious boy who lives in protagonist Marco's basement, and turns the kid's life into an insane nightmare.

%%* BasementDweller: Read the title.
* BodyHorror:[[spoiler:He's a walking mass of yellow goo that turns himself ''inside out'' frequently.]]
* BlobMonster:[[spoiler:His true form.]]
* CreepyChild:[[spoiler:Not even a human one.]]

!!King Jellyjam

The mascot of the titular camp in ''The Horror at Camp Jellyjam''. A disgusting smelling purple BlobMonster that sweats snails, and must be constantly cleaned and bathed by his slaves.

* ChildEater: He eats campers that try to take a break from washing him, and doesn't appear to live off of anything else.
* EldritchAbomination: According to WordOfGod, he was formed when a camper left a bowl of gelatin inside a radioactive, snail-infested cave.
* {{Expy}}: Shares some similarities with [[StarWars Jabba the Hutt]] - both are hedonistic [[BlobMonster blob monsters]] that own slaves, have said slaves eaten if they displease them, and suffocate to death [[HoistByHisOwnPetard via their own means.]] Also, see SatanicArchetype.
* DarkLordOnLifeSupport: He's too massive to leave his cave, and needs to have his deadly smell constantly washed away to survive. Ironically, this continued dependence leads to his downfall.
* HoistByHisOwnPetard: He suffocates on his own stench after his child slaves stop washing him. This is likely because he spent so much time being washed, he never actually had time to adapt to the smell. In the end, his desperate attempts to sustain himself were what destroyed him.
* ItsAllAboutMe: He sees the children and counselors as nothing more than [[LackOfEmpathy tools to keep himself alive]], and has brainwashed the counselors into dedicating their lives to serving "The Master".
* ManipulativeBastard: Acting through the counselors, he plays on the children's desire for rewards and victory, which leads them into his slimy clutches.
* MindControlConspiracy: Camp Jellyjam is one giant front to gain new slaves for him.
* MistakenForQuake: His burps are powerful enough to shake the ground.
* SatanicArchetype: A giant underground monster who manipulates power-hungry, competitive people into being his toys. Sound familiar?
* WalkingSpoiler: To the point where he's not even on the original cover of his book. The new cover art changes this, though.
* WeaksauceWeakness: His stench. His lungs are apparently so weak that taking it in for one moment is enough to kill him.
* YouHaveFailedMe: What happens to any camper that stops washing him, even for a moment.

!!Lord High Executioner

A nightmare from the Middle ages, this man is a court executioner who will let nothing stand in the way of his victims...not even time and space.

* AffablyEvil: He isn't above throwing money to peasants for helping him.
* AnAxeToGrind: Though he doesn't carry it unless he's preparing for an execution.
* BadassNormal: Doesn't have any supernatural powers, but is vicious enough to intimidate the local wizard.
%%* BadassBeard: the TV episode.
* BadassCape: He sports a billowing black cape when first seen in the tower.
* BloodKnight: The lengths he's willing to go to carry out his job are truly frightening.
* DarkerAndEdgier: Look at his [[AnAxeToGrind cover image]] and compare it to the rest.
* {{Determinator}}: He travelled through time itself just to capture and kill two kids.
* TheDragon: To the unseen evil king.
%%* EvilSoundsDeep
* KnightOfCerebus: Ruthless, competent, lacking in any humorous or campy quirks and [[spoiler:implied to have ''murdered Eddie and Sue's parents''.]]
* RedEyesTakeWarning: On the cover, anyway.
* TheSociopath: Thinks absolutely nothing of his horrific occupation.
* TokenHuman: Apparently in the 2015 movie. Every other villain has supernatural powers or origins.
* WouldHurtAChild: And won't let anything stop him.

!!Masked Mutant

A comic book supervillain with the power to shapeshift, the Masked Mutant travelled to our world where he met his biggest fan...and tried to kill him.

* ActuallyADoombot: The Mutant encountered by Skipper and the Galloping Gazelle is actually a henchman with similar shape-shifting abilities. He's killed by the real deal.
%%* AffablyEvil
* ApologeticAttacker: As evil as he is, he does apologize to Skipper before attempting to kill him, as if he feels he has no choice.
* BadAss: The reason he targeted Skipper in the first place was because he ''got bored with fighting superhumans.''
%%* BadassCape
* BlueAndOrangeMorality: He knows full well he's in a comic book, and therefore doesn't believe his actions are going to have any moral impact.
* CardCarryingVillain: A very self-aware example. He repeatedly boasts about being a supervillain.
* CoolMask: It makes him look like a demonic [[Franchise/Batman.]]
* DangerouslyGenreSavvy: He has no trouble manipulating Skipper into his clutches. [[spoiler:Unfortunately, he isn't savvy enough to avoid the boy's winning move.]]
* TheDogWasTheMastermind: Hands up, who guessed Libby was the villain?
* EvilRedhead: As "Libby", his human guise.
* ForTheEvulz: The reason why he kills his henchman.
* GeniusBruiser: A ruthless combatant and cunning manipulator who employs some pretty complicated gadgetry.
* HoistByHisOwnPetard: His shape-shifting ability ends up dooming him when Skipper tricks him into turning into a liquid, which he cannot revert back from.
* HollywoodAcid: Morphs into a large wave of this to kill Skipper. It doesn't work.
* HumanoidAbomination: We are never told exactly what he is, but he's far from human.
* InvisibilityCloak: His lair employs this to keep away enemies, as well as to lure a curious Skipper into his trap.
* KickTheSonOfABitch: His murder of Molecule Man, who was apparently just as AxCrazy and cruel as his boss.
* LargeHam: In the TV episode, he absolutely ''devours'' every scene he's in.
* ManipulativeBastard: As "Libby" he tries to discourage Skipper from heading to the invisible base, while knowing full well he's going to do it anyway after reading the latest comics.
* NoodleIncident: No explanation is ever given for how he came to the real world.
* PickOnSomeoneYourOwnSize: Toward Skipper. His insane logic is that since this kid knows everything about him while the heroes of his world are complete idiots, he'll make a perfect opponent. [[spoiler:Surprisingly enough,he was right.]]
* PopCulturedBadass: In his "Libby" persona, he has his own collection of comics. The fact that they are ones Skipper considers lame and poorly written just sells his disguise even more.
* PunchClockVillain: The whole point of his existence is to be the perfect villain for his target audience. Then again, he seems to really ''enjoy'' his job.
* ShapeshiftingSeducer: Tries to gain Skipper's trust in the form of ''an attractive young girl'' named Libby. Thankfully, this remains strictly platonic.
* ShapeshifterDefaultForm: A towering figure with a purple mask and cape. However, we never see him unmasked, and it's not even clear if this is his true form.
%%* TooDumbToLive
* TrickingTheShapeshifter: How Skipper takes him down.
* TheOnlyOneAllowedToDefeatYou: Kills his henchman for trying to finish off Skipper before him.
* VoluntaryShapeShifting: Supposedly accomplished by "rearranging his molecules."
* VictoryIsBoring: Apparently his motive for targeting Skipper. He was always one step ahead of the heroes in his world, and in his opinion, the kid was the only one who would provide a challenge.
* TheWorfEffect: By way of a twelve year old.
* WorthyOpponent: To a degree. He takes time to explain what's going on to Skipper so he won't die too confused.

!!Monster Blood

A mass of growing goo and monster of the "Monster Blood" series.

* AttackOfThe50FootWhatever: What results from it's consumption.
%%* BlobMonster
%%* ExtremeOmnivore
* GenericDoomsdayVillain: This is to be expected, since it's a mindless lifeform, but it's creator, Sarabeth, is a more straightforward example. Other than wanting to keep Evan's aunt as a slave, she has no personality or motivation whatsoever, and is simply in the story to provide an explanation for the ever growing slime.
%%* HungryMenace
%%* MutagenicGoo
* SealedEvilInACan: And some sap always winds up opening it...
* SeriesMascot: It forms the title of the series.

!!Mr. Mortman

The librarian of Dark Falls and the main antagonist of ''The Girl Who Cried Monster''. Although he looks like a normal, albeit slightly overweight, human, Mortman is actually a monster who eats insects, reptiles, fish... and sometimes people.

* BaldOfEvil: He's described as having male-pattern baldness, and appears this way in the TV episode as well.
* BodyHorror: His transformation into his monster form. For example, his eyes stick out of his head on stalks.
* ChildEater: Although he mostly eats creepy crawlies, he shows more than a little interest in eating Lucy, especially in the TV episode.
* FourEyesZeroSoul: Although the actual book never mentions him wearing glasses, the cover art shows him with a pair, and the TV episode followed its example.
* HorrorHunger: Eats a ''whole'' lot of really nasty things.
* IAmAHumanitarian: Although he seems to prefer eating turtles and flies, Mortman ''will'' eat a human (such as snooping kids).
* VoluntaryShapeshifting: He can turn into a monster seemingly at will.
* WeaksauceWeakness: He can be stopped in his tracks by knocking the card catalog into disarray. This appears to be a nod to the famed obsessive-compulsive behavior of vampires re: seeds.

!!Mr. Toggle

The main villain of ''Piano Lessons Can Be Murder''. An inventor and robotics expert obsessed with creating beautiful music. He secretly operates a music school via posing as the janitor, to find people with beautiful hands which he then chops off for the sake of converting them into machines because he can't create hands from scratch.

* BrilliantButLazy: He's tried creating robotic hands from scratch but he kept failing, so he decided the easier thing to do would be to kill people, steal their hands, and then install wiring inside them so they can play music. In the TV show, it seems as a child he took piano lessons but was too lazy to actually practice. His teacher mentions he was a very clever child, but also very lazy.
* CoolAndUnusualPunishment: In the TV show, his former teacher is punishing him by making him practice the piano for eternity.
* TheDogWasTheMastermind: At first it seems Dr. Shreek is a madman with an unhealthy obsession regarding music and hands, but then it turns out he was a robot the whole time... and ''Toggle'' is the aforementioned madman with the unhealthy obsession.
* EvilTeacher: His "greatest creation", Dr. Shreek.
* TheManBehindTheMan: He created Dr. Shreek and made him the figurehead for the music school so he could stay behind the scenes and continue killing people.
* NeverFoundTheBody: In the book, the ghosts of his victims reclaim their hands, then carry him away to an unknown fate.
* PsychopathicManchild: In the TV version, when the ghost woman finally confronts him over the evil he's done, Toggle begins whining like a little boy, saying "I tried my best!"
* SelfMadeOrphan: Implied in the TV show, where it appears the ghost who has been following Jerry was Toggle's old music teacher ''and'' may have been his mother. She also appears to be his first victim.
* SerialKiller: Has a very big body count by the time Jerry becomes a student at the school. Just look at the number of hands he's stolen in the TV episode as further proof of this.
* WouldHurtAChild: He's implied to have already killed several and planned to do the same to Jerry.

!!Mud Monsters

From ''You Can't Scare Me!'' The Mud Monsters are zombies who live in the depths of Muddy Creek. Once a year they rise out of the creek to search for victims to drag back with them into the mud.

* CoveredInMud: They ''are'' mud.
* OurZombiesAreDifferent: At this point, they're basically half human, half mud.
* TalkingTheMonsterToDeath: In the TV show, Courtney does this by going on a rant towards the Mud Monster in order to stall it long enough for it to freeze due to the frigid temperatures.
* TragicMonster: They were originally poor settlers forced to live in huts alongside Muddy Creek because the richer citizens of the nearby village wanted nothing to do with them. On the night of a violent storm, the creek was flooded, washed the village away, and the settlers drowned to death.

!!Princess Nila

A reporter from the egyptian newspaper, "The Cairo Sun", Nila befriends Gabe and his family in "Return of The Mummy." In reality, she's actually a thousand year old egyptian princess who hopes to use the Hassad family as a means to resurrect her brother. A character resembling her appears in a promotional shot for the Goosebumps movie.

* AmbitionIsEvil: Wants to resurrect her brother, Khor-ru, so they can make a comeback and take over Egypt together.
* {{Animorphism}}: Can transform into a scarab, which is somehow connected to her amber pendant.
* BadassPrincess: A non-combat example. She's not particularly strong, but the lengths and steps she takes to find her brother are impressive.
* BitchInSheepsClothing: To Gabe and Sari's horror.
* CainAndAbel: Her brother tries to ''strangle'' her after waking up.
* EvenEvilHasLovedOnes: She may be a sociopath, but Nila was willing to go to extremes to bring her brother back so they could rule together. She also mentions her mother as the one who named her.
* Really700YearsOld: Pretty awkward, considering Gabe's uncle had a crush on her...
* SoulJar: Her scarab pendant. It's apparently what allows her to maintain human form.
* ShootTheShaggyDog: Waits for thousands of years to begin her plan, creates a new identity, manipulates an archaeological dig, harnesses Gabe's power, brings back Khor-ru...only for her brother to want ''nothing'' to do with her, and then get trapped in scarab form thanks to Gabe's interference.
* ShapeshifterModeLock: Her ultimate fate, after Gabe smashes her pendant.
!!The Sadler Trio

!!'''Slappy'''
[[quoteright:158:http://static.tvtropes.org/pmwiki/pub/images/rsz_1slappy_the_dummy2_by_wicker123_916.jpg]]
-->''Voiced by: Annick Obonsawin (Television Series)''

The BigBad of the "Night Of The Living Dummy" series of books and currently the one reoccurring character to appear in the most books.

* AscendedExtra: Didn't come to life until the very end of ''Night of the Living Dummy'', after the heroes destroyed the main antagonist, Mr. Wood. The sequels obviously focus on Slappy, though he occasionally shares the spotlight with other dummies.
* BigBad: Of his mini-series.
* BigBadEnsemble: TheMovie will have him somehow unleash an army of villains from the books, including Priestess Nila, Count Nightwing, and Sarabeth.
* BigBadWannabe: He may be the face of the franchise, but Slappy is actually a small fry compared to other, more powerful antagonists. His plans are usually thwarted by other dummmies, and in the "Horrorland" series, he's just another minion of the Menace. While he does kickstart the events of the movie, it's unlikely the other villains will take orders from him.
* BadBoss: The way he treats his intended "slaves" should say enough, but he also acts this way to Rocky.
* BreakoutVillain: Arguably the most well known villain of the series.
%%* DemonicDummy
* DemonicPossession: Happens at the end of "Bride Of The Living Dummy", and possibly at the end of the TV adaptation of "Night Of The Living Dummy III"
* {{Determinator}}: His owners are always in for a surprise when they try to get rid of him.
* EvilRedhead: Though he's a brunette in the books.
* EvilerThanThou: Meets one in ''Slappy's Nightmare'', [[spoiler: another ventriloquist dummy trying to take his place]].
* {{Expy}}: Of Chucky from ''Film/ChildsPlay''.
* FailureIsTheOnlyOption: His goal is to find human slaves, which he has made no progress with since his first appearance.
** ''Finally'' averted in [[spoiler: ''Goosebumps Most Wanted: Son of Slappy.'' After Jackson spends the entire book trying to fight off Slappy's hypnotic control, he defeats Slappy and hides him...[[DownerEnding only for his bratty sister, Rachel, to find Slappy, team up with him, and they ''both'' end up controlling him and making him do terrible things]]. The reason? Because Rachel was tired of her "perfect brother" making her look bad.]]
* ForTheEvulz: Besides getting "slaves", this is pretty much his only motivation. He even says "Evil is its own reward" in ''Son of Slappy''.
%%* FromNobodyToNightmare
* HypocriticalHumor: This:
-->'''Slappy:''' Wrapping a kid in the drapes is something ''I'' would do just for fun. But Stella? She's totally unbalanced. She's ''sick''!
* IHaveYouNowMyPretty: His interactions with his female owners are pretty disturbing to read as an adult.
%%* JerkAss
* JokerImmunity: Gets destroyed (or at least disposed of) at the end of most books, yet always returns for another sequel.
* LaughablyEvil: He's still a prick, but he's much more playful and mischievous than outright sadistic.
* PoliticallyIncorrectVillain: Besides being a raging misogynist, he also mocks people's weight and age. At least he avoids racism.
* VillainProtagonist: ''Slappy's Nightmare'' is told from his perspective. Stine makes him slightly more sympathetic by pairing him with an even worse antagonist.

!!Tara Webster

Michael's bratty, sadistic little sister in ''The Cuckoo Clock of Doom''.

* ForTheEvulz: She torments her brother simply because she enjoys making him miserable.
* InSeriesNickname: "Tara the Terrible".
* RetGone: Due to a flaw in the clock, she is erased from existence. Michael decides he will probably find a way to go back and get her sometime...maybe.
* ParentalFavoritism: Their parents obviously favor her, believe her to be completely innocent, and call Michael a liar when he defends himself.
* TheSociopath: She never shows any remorse for the horrible things she does to her brother, which include getting him beaten up and ruining his birthday party.

!!Uncle Al

* AFatherToHisMen: Zigzagged. He seems pretty warm and friendly before revealing a much more dark and cruel side. In the end, though, he was doing it all for the good of his campers.
* BadassMustache: His first scene has him scare off a bunch of leopard like creatures threatening the campers.
%%* BitchInSheepsClothing
* DrillSergeantNasty: He doesn't even hire a nurse at his camp because he doesn't believe in "pampering" his boys.
* HumanAlien: Revealed to be this in the twist(along with everyone else at the camp).
%%* JerkassFacade
%%* PunchClockVillain
* SecretTestOfCharacter: The entire plot is revealed to be this for Billy.
* ScoobyDooHoax: He, along with all the other campers, invented a monster that's said to live in the forbidden bunk.
%%* TrainingFromHell
%%* WalkingSpoiler
* WellIntentionedExtremist: He's actually a nice guy who wants to ensure his campers' success, it's just that his methods are extremely dangerous and unethical.

!!Vanessa

A witch who was the main villain of ''Chicken Chicken''. She curses two children into slowly, and painfully, transform into actual chickens because they made her drop her groceries by accident.

* TheBadGuyWins: [[spoiler: When Crystal and Cole burp loudly without saying "Excuse me," Vanessa says "Pig, Pig."]]
* DarkIsEvil: She dresses entirely in black.
* DisproportionateRetribution: And ''how''. The torture she puts Crystal and Cole through is totally unwarranted, even if they knocked her over, and the only reason she didn't curse their friend was because he gave an offhanded apology as he was running away. Her actions made ''Chicken Chicken'' turn out to be one of the most despised entries in the series.
%%* HarmfulToMinors
* HateSink: One of the most reviled characters in the entire franchise, and with good reason.
* KarmaHoudini: She gets away with cursing Crystal and Cole [[spoiler: twice.]]
%%* WickedWitch
%%* WouldHarmAChild

!!Wilson Schlamme

Jack's rival in ''How I Learned To Fly''. An arrogant kid who seems to be the best at ''everything''.

* TheAce: He effortlessly creates balloon animals in seconds, has a top-of-the-line bike and roller blades, we could go on forever. Even his dog is better than Jack's.
* AnythingYouCanDoICanDoBetter: If he and Jack are both chewing gum, he insists that the bubbles he blows are bigger and rounder than Jack's. If they aren't, [[SoreLoser he pops Jack's bubble all over his face]].
* CelebrityIsOverrated: His pursuit of fame and glory eventually causes him to move away and lose his social life, while Jack stays behind, returns to normal, and gets the girl.
* JerkWithAHeartOfGold: He seems to genuinely want to please Mia, even if his tactics are inscrutable.[[spoiler:In the end, the real reason he loses is because he can no longer be with her.]] He also rescues several endangered people as Wonder Wilson, and offers Jack a place as his sidekick, although the latter may have just been him taunting Jack.
* TheRival: He competes with Jack for everything, especially Mia's affections.
* SmugSnake: In the end, his need to make everything a contest and to be the best at everything causes him to lose his social life and his chances with Mia.

[[folder: Other Characters]]
!!'''Dr. Deep'''

Billy and Sheena's uncle, he's a marine biologist who discovers all sorts of strange phenomena that endanger him, his niece, and nephew.

* AdultsAreUseless: He does try to avoid it, though.
%%* CloudCuckooLandersMinder: Around [[{{Keet}} Billy]].
* DistressedDude: Billy and Sheena always have to save him from whatever menace he's disturbed. One wonders how he's able to survive without them.
* HeelRealization: After the fight to save the Mermaid from the crooks, he still seems to be thinking of capturing her. When the zoo workers arrive, though, he tears up their reward money.
* HorribleJudgeOfCharacter: Attempts to reason with his treacherous assistant Alexander, even after the latter ''tried to kill'' him and the kids earlier that night.
* ReasonableAuthorityFigure: He's useless in dangerous situations, but he ''does'' try his best to keep the children from danger.
* ReedRichardsIsUseless: No, Dr. Deep, selling a freaking ''Mermaid'' to a children's zoo isn't a good idea.

!!'''The Shopkeeper'''

The owner of a mask shop in ''The Haunted Mask''. Also appears briefly in ''The Haunted Mask II''. He creates masks of living flesh to conceal his own deformities (see AllThereInTheManual below) but they always become corrupted and ugly, forcing him to keep making new ones. In the ''Goosebumps'' TV series, he's played by Canadian actor Colin Fox.

* AdaptationExpansion: In the TV episode of ''The Haunted Mask II'' he has a greatly expanded role, wherein he gets [[GrandTheftMe taken over]] by the original Haunted Mask.
* AllThereInTheManual: His backstory is provided in the ''Goosebumps Collector's Caps Book'', wherein it's revealed he was injured in a high school chemistry accident, leading him to begin creating the masks.
* MultipleChoicePast: Although, as noted above, he is given an official backstory in the "Goosebumps Collector's Caps Book", his origins and exact motivations for creating the masks are never explicitly stated in either the books or the episodes. Furthermore, the Goosebumps Wiki states that he was ''born'' ugly/deformed (as opposed to becoming so via an injury). It's really rather unclear what his actual past is.
* EveryoneCallsHimBarkeep: The Shopkeeper's real name is never revealed (not even in the backstory described above).
* DarkIsNotEvil: Despite his all-black attire and generally slightly threatening manner, he isn't that bad of a guy, just sort of moody and depressed.

* JerkWithAHeartOfGold: In the TV episode. Although grumpy and moody, he still tells Carly Beth how to remove the mask, out of sympathy for her plight.
* ReedRichardsIsUseless: The pioneering this guy did in growing artificial, lifelike faces would have ended disfigurement, had he taken the time to publish his discoveries.
* MadScientist: Quite possible with this guy. If not mad, then at the ''very'' least eccentric.

!!'''Alexander [=DuBrow=]'''

Dr. Deep's assistant. A nice guy, but a terrible cook. After his boss captures the mermaid, Alexander decides to steal it for himself and make a fortune. He's last seen under attack by the creature's vengeful family.

* AssholeVictim: He was willing ''to murder children just to strike it rich.'' Needless to say, no one's complaining when the mermaids drag him to his doom.
* BlondGuysAreEvil: He's described with "wavy blond hair" and crinkling blue eyes.
%%* {{Greed}}
* HateSink: His actions are meant to show Billy and Dr. Deep the dangers of discovery and ambition.
* HumansAreTheRealMonsters: He is the first antagonist to have no supernatural qualities or goals.
* KarmicDeath: Possible, since he never appears in the rest of the book or its two sequels.
* LackOfEmpathy: Has no qualms about betraying his boss and allowing him to be murdered as long as he gets paid.
* LethalChef: The mermaid is the only one who can stand his cooking.
* TheMole: We never find out who he was working for, though.
* NotSoDifferent[[spoiler:Just as Billy (originally) wanted to use the mermaid for fame, Alexander wants to use her for fortune.]]
* OnlyInItForTheMoney: "The Zoo was going to pay 1 million dollars for this mermaid. But my ''new'' boss will pay me 50 million!''
* ReasonableAuthorityFigure: [[spoiler:Subverted. It's all an act.]]
* WhatHappenedToTheMouse: We never find out what happens to him and his cohorts after the Mermaid attack. [[CabinInTheWoods Maybe it's better that way.]]

!!'''Courtney'''

A popular, smart girl in ''You Can't Scare Me!'' who is seemingly not afraid of anything, but is very gullible when it comes to local legends about Mud Monsters.

* TheAce: And ''how''!
* AlphaBitch: She's popular, good-looking, and virtually nothing can faze her.
* DesignatedVillain: She doesn't do anything bad except piss off the protagonists by being perfect at everything.
* InsufferableGenius / SmugSnake: Especially in the TV episode, where she mocks the protagonists for trying to scare her and actually ''talks the monster to death''.

!!''Harrison Sadler''
An obsessive, bitter, and determined old man, Sadler sees himself as a ghost hunter. He hides out in a cave near his hometown and spies on three ghostly children in the area, seeking to capture them. When Jerry and Terry Sadler show up, he finds his chance.
