[[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.

!!'''Brandon Plush'''

The VillainProtagonist of ''Headless Halloween'', Brandon loves scaring people, especially those weaker than him like his little sister or his nerdy cousin. One year, Brandon decided to get revenge on his science teacher by playing a few mean Halloween pranks on him, [[spoiler: but ends up getting chased off a ravine and dying. He then has to perform three good deeds in order to come back to life.]]

* AesopAmnesia: His teacher and mother are frequently trying to show that his bullying behavior has consequences but he never listens. [[spoiler: Not even dying is enough to set this kid straight.]]
* AssholeVictim: [[spoiler: It's impossible to feel sorry for this kid after he receives his comeuppance.]]
* TheBully: A rare example in that he's a bully who's also the protagonist.
* HateSink: One who seems to have been an intended example.
* IAteWhat: He's tricked into eating a doughnut full of worms, and when finds out, he's forced to eat the whole thing.
* InfantImmortality: [[spoiler: Averted.]]
* JerkWithAHeartOfJerk: [[spoiler: He doesn't actually care about helping other people, but he'll do it if it means he can come back to life.]]
* JustJokingJustification: He frequently says "Oops, just joking" when pulling pranks.
* KilledOffForReal: [[spoiler: He actually dies halfway through the book, and is tricked into believing he could come back to life. It turns out that, no, he's dead for real.]]
* LackOfEmpathy: He's incapable of feeling sorry for anyone unless he's forced to.
* LaserGuidedKarma: [[spoiler: He falls to his death, is then tortured by Norband and the other dead children, forced to save three scared people thinking it will undo his death, and is then told this is a lie. At first, the ending seems to make him a KarmaHoudini as he is more than happy to go back to scaring people, but he's ''still'' dead and there's no indicator he'll actually be allowed out of the Other Side.]]
* NightmareFetishist: He loves seeing people scream, cry, and vomit from fear. [[spoiler: Of course, when he's on the other side of this naturally he's all talk and no game.]]
* TheSociopath: Brandon has no redeeming qualities and gets off solely on tormenting those around him. What's more, while his mother is clearly disturbed by his destructive tendencies, his dad actually thinks it's funny and encourages him.
* VillainProtagonist: A clear example of a main character who deserves everything they suffer.

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

The main character of ''The Haunted Mask'', a tormented and meek young girl 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.
* EvilIsNotAToy: She steals the mask because she believes it will help her avenge herself on her tormentors, unaware of how dangerous the mask really is until it becomes her face.
* [[OnlySaneMan Only Sane Girl]]: In the Horrorland series, she soon becomes the most levelheaded member of the group.
* ShrinkingViolet: She was a very timid girl easily frightened by just about everything and lacking the resolve to stand up for herself against her tormentors. After her first encounter with the Haunted Mask, she grew out of this trope and became much more willing to assert herself against the likes of Steve and Chuck.
* 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.

!!'''Crystal and Cole Sanders'''

Siblings who live in the farming town of Goshen Falls. Their lives become an unending nightmare when they catch the ire of Vanessa, the local witch. As revenge for knocking into her and making her drop her groceries (without apologizing) she curses the two by uttering the phrase ''Chicken Chicken''. The Sanders siblings are considered to be two of the biggest [[TheWoobie Woobies]] in the whole franchise because of how disproportionate their suffering is.

* BalefulPolymorph: The curse Vanessa put the two through is slow and painful, and also makes them act like chickens against their wills.
* BodyHorror: They both grow feathers which are painful to remove, Crystal's lips become hard and bumpy like a beak, and they can feel their eyes move to the sides of their heads while their hands become claws. The book goes into perfect detail about how long and painful this process is.
* ButtMonkey: But exaggerated to such a degree that it makes ''Chicken Chicken'' uncomfortable to read.
* CantGetAwayWithNothing: [[spoiler: ''Chicken Chicken'' ends with Crystal and Cole being cursed again by Vanessa simply because Cole let out a loud burp without saying "excuse me" and Crystal laughed at it.]]
* NotNowKiddo: Their parents fail to notice that their children have suddenly grown feathers, and that their daughter's lips have turned into a beak. In fact, her mother just assumes Crystal needs chapstick.
* RedheadedHero: Crystal has beautiful red hair and she's often complimented on it by strangers.
* YouAreWhatYouHate: The two absolutely can't stand chickens and hate that their parents moved to Goshen Falls just so they could farm them, which makes their transformations all the more horrible.

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

The main characters of ''Monster Blood.''

* AesopAmnesia: Evan never learns that getting involved with Monster Blood will not lead to anything good.
* BerserkButton: Andy ''hates'' to be called by her real name, Andrea.
%%* BigFriendlyDog: Trigger
* ButtMonkey: Evan. Nothing ever works out for him, his parents are always leaving him with other relatives he doesn't like, he's picked on and beaten up, and he finds himself stuck in situations involving a horrible living blob creature.
* CassandraTruth: When Evan tells Andy that no one believed his Monster Blood stories, her response is along the lines of "no shit, Sherlock".
* TheChewToy: Evan. When he's not being beaten up, he's being used by his obnoxious cousin Kermit for experiments or enduring something horrible thanks to Monster Blood.
%%* PluckyGirl: Andy.
* RedHeadedHero: Evan, but for a loose sense of the word hero due to how much he brings trouble on himself for always using Monster Blood.
* 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!'']]

!!'''Harry and Alex Altman'''

The main characters of ''Ghost Camp'', Harry and Alex are brothers who're spending the summer at Camp Spirit Moon. As the only non-veteran campers, they find themselves the targets of some... odd pranks by the other kids. For a series that really likes focuses on SiblingRivalry, the two of them strangely get along quite well.

* AnnoyingYoungerSibling: Averted with Alex.
* CompellingVoice: Alex has an ''amazing'' singing voice for someone so young, and everyone knows it. So, at the end, when Alex's singing is suddenly off-key, Harry realizes [[spoiler: it's because Alex is being possessed by Elvis]].
* DemonicPossession: [[spoiler: Alex ends up getting possessed by Elvis. When Harry realizes this, Elvis begs him not to tell anyone, and the book ends without revealing if Elvis ever left Alex.]]
* DesignatedVictim: They're the butt of some disturbing pranks because they're the new kids. [[spoiler: And also because they're the only kids who are ''alive''.]]
* DoesThisRemindYouOfAnything: [[spoiler: Lucy revealing to Harry the truth about the camp and begging Harry to let her use his body is disturbing similar to a discussion one would have about engaging in sex, to the point that when Lucy tries to possess Harry without his permission it comes across as a metaphor for sexual assault.]]
* TheEeyore: Alex can be moody.
* FoolishSiblingResponsibleSibling: Subverted, in that said roles aren't really needed for the two. While Harry sometimes takes the lead because he's older, he doesn't have to reign in Alex because Alex doesn't act like an annoying pest.
* MindRape: [[spoiler: Lucy tries this on Harry, Elvis ends up succeeding on Alex.]]
* OnlySaneMan: Harry and Alex both end up being this throughout the majority of ''Ghost Camp'' because of how the other campers treat them.
* PuppyLove: Subverted. Harry appears to be heading this way with Lucy, [[spoiler: and then she tries to take over his body.]]
* SiblingRivalry: Averted. They get along well, which might be because Harry's only a year older than Alex.

!!'''Gary Lutz'''

The constantly bullied and tormented protagonist of ''Why I'm Afraid Of Bees''

* BodyHorror: Due to a mishap, when he tries to swap bodies with a handsome local, he instead swaps bodies with a ''bee''.
* ButtMonkey: Hands down the biggest one in the entire series, and that's saying something. He has ZERO friends, his sister hates him, his beekeeper neighbor is a sadist who loves tormenting him with his biggest fear, and when he finally has a chance to escape his miserable life, he's turned into a bee. Gary isn't just a ButtMonkey, he's in full-on [[TheWoobie Woobie]] territory.
* TheChewToy: He suffers a lot of injuries, especially on his bike, and that's before he's turned into a bee.
* TheDogBitesBack:After Dirk,the jock who has his body,refuses to give it back,Gary finally has enough and coerces his fellow bees into divebombing him.
* DeusExMachina: He remembers too late that bees die after using their stingers, but instead, the shock of his sting somehow puts him, Dirk, and the bee back into their rightful bodies.
* EarnYourHappyEnding: Does he ever. After getting his body back, he becomes much more confident and popular, although he does retain some of the bee's senses and characteristics.
* InSeriesNickname: "Lutz the Klutz".
* StrawLoser: He sucks at sports, he doesn't have a single friend, and he spends most of his time on the Internet (or what passed for Internet in the early/mid-90s).
* TheUnfavorite: Even his mom and sister seem to delight in making fun of him.

!!'''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.
* NoSenseOfPersonalSpace: Luke likes to pinch Lizzy and their friend Clay, calling himself "The Mad Pincher." [[spoiler: It comes in handy when they realize the "No Pinching" signs in Horrorland were there for a reason...]]
* 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.

!!'''Lucy Dark'''

A girl with a fascination for monster stories, but her fascination turns to fear when she learns the local librarian actually ''is'' a monster and no one will believe her. She's ''The Girl Who Cried Monster''. Has become something of an EnsembleDarkhorse due to a certain scene from the book and TV show.

* BigBrotherBully: Well sister. She especially loves freaking out her little brother with her stories.
* CryingWolf: She's annoyed pretty much everyone around her with all her monster stories so of course they won't believe her when she learns Mr. Mortman actually is one. However, when she gets photographic proof her parents change their mind... [[spoiler: and then they eat him]].
* CuteMonsterGirl: [[spoiler: Well she hasn't gotten her fangs yet, but they're coming.]]
* DeadpanSnarker: Enjoys snarking at her parents. At one point her mother worries about this "monster phase" she's going through, and Lucy retorts "''Life'' is just a phase I'm going through."
* TheDeterminator: After witnessing Mr. Mortman transform, she takes it upon herself to expose him no matter how many people don't believe her and how dangerous it'll get.
* NightmareFetishist: Her love for monster tales.
* NonMaliciousMonster: [[spoiler: The only reason her parents kill Mr. Mortman is to protect their family's identity as monsters, which seems more justified when you remember ''he'' tried to kill Lucy to protect his secret as well. Other than that, they're not hostile. There's a specific moment in the TV show where it looks like her parents are considering eating her best friend for dessert, and she seems very horrified before her dad asks if said friend will join them for pie.]]

!!'''Michael Webster'''

The long suffering brother of Tara Webster and protagonist to Cuckoo Clock of Doom.

* DontMakeMeTakeMyBeltOff: It's subtly implied this is how his dad deals with him whenever Tara blames him for something.
* EarnYourHappyEnding: [[spoiler: Setting the clock back to the way it should be not only restores Michael's timeline, but also erases Tara from existence due to its flaw (it doesn't have 1987, the year Tara was born, on its year dial). Michael's life becomes ''extremely'' more enjoyable, but says he might go back and save her. Maybe.]]
* HumiliationConga: Has his 12th birthday ruined, is seen in his underwear by his crush, get's de-aged into a toddler then a baby (which includes a diaper change)....
* TheUnfavorite: His parents practically worship Tara and treat him like garbage. [[spoiler: When she's gone, his parents are no longer abusive.]]

!!'''Ricky Beamer'''

The nerdy protagonist of ''Calling All Creeps!'' who mistakenly ends up as the leader of a group of reptilian aliens who want to TakeOverTheWorld.

* ButtMonkey: He's constantly picked on by his classmates and by [[AlphaBitch Tasha]], the head of the school newspaper. Let's just say his FaceHeelTurn at the end isn't entirely out of nowhere.
* FaceHeelTurn: When he learns that his classmates will be his slaves once they've turned into Creeps, he decides that if you can't beat 'em, join 'em.
* GettingCrapPastTheRadar: His revenge plot against Tasha is more or less the same idea as writing "For a good time, call..." on the bathroom wall.
* MistakenForBadass: After his revenge plot goes wrong, the Creeps assume he is their leader.
* WhosLaughingNow: When he does his FaceHeelTurn.

!!'''Bradley "Skipper" Matthews'''

A comic book nerd who discovers his favorite supervillain's HQ right in his own town... and soon finds himself starring in the comic book, against his will.

* EvilLaugh: In the TV episode, he does this as an IronicEcho of the Masked Mutant's laugh after defeating him.
* MistakenForBadass: The Masked Mutant assumes that Skipper must be a formidable superhero, and thus the perfect nemesis for him.
* PopCulturedBadass: He's not so much a comic book collector as a comic book ''connoisseur''. In the end, his in-depth knowledge of the Masked Mutant's background is what helps him beat him.
* TrickingTheShapeshifter: He convinces the Masked Mutant that he can only be destroyed by acid. The Mutant then forgets that he can only turn into a solid and back, but once he turns into a liquid, he's stuck in that form.

!!'''Steve Boswell'''

The primary bully figure in ''The Haunted Mask''. He loves tormenting Carly-Beth Caldwell, but gets a taste of his own medicine when she acquires her evil mask. He's the protagonist of ''The Haunted Mask II'' when he finds a mask of his own. In the TV show adaption of the second book, Steve's mask makes him the puppet of Carly-Beth's mask and he has to serve him if he wants his face back.

* ADayInTheLimelight: As a result of ''The Haunted Mask II''.
* AscendedExtra: He became the main character of ''The Haunted Mask II'', which stands out a bit more than you'd think as Steve was also the narrator, unlike Carly-Beth in the first book.
* TheBully: Similar to Conan Barber in the ''Monster Blood'' books, he's a bully in every ''Haunted Mask'' book he's appeared in. However, [[spoiler: he's also a bully whose victim has begun asserting herself and he becomes rather pathetic as a result]].
* ButtMonkey: In ''The Haunted Mask II'' to different degrees in the book and television show. In the book he's tortured by a bunch of bratty first graders while his mask slowly turns him into an old man. In the TV show, the mask still turns him into an old man, but he's now being controlled by the Haunted Mask.
* BreakTheHaughty: ''The Haunted Mask'' and ''The Haunted Mask II'' show him getting what he deserves. Unfortunately, due to the latter being retconned thanks to ''The Scream of the Haunted Mask'', Steve remains a jerkass.
* ChildHater: As punishment for a prank he pulled Steve was forced to coach a first grade soccer team, but he grows to absolutely loath the kids because they make things difficult for them.
* KidsAreCruel: He's an example of this and also a victim of it.
* LaserGuidedKarma: Is scared shitless by Carly-Beth in the first book and then treated like crap by the first graders in the second book.
* TookALevelInKindness: [[spoiler: The ending of ''The Haunted Mask II'' in the TV show proves he actually does care for Carly-Beth when he stops the Haunted Mask from taking control of her, acting as the symbol of love needed to remove his mask.]]

!!'''Tamara Baker'''

Of the short story ''Broken Dolls''. Tamara likes to collect dolls, but unfortunately for her, her younger brother likes to break them. Regardless, Tamara discovers she has to save her brother from being turned ''into'' a doll thanks to a mysterious old woman.

* CoolBigSis: While Neal certainly doesn't think of her as this, and while they do argue a lot, Tamara proves that she cares about him a ''lot'' by putting herself into mortal danger in order to save him from spending the rest of his life as a doll.
* KidHero: When she realizes something strange is happening to her brother, she puts two and two together and figures out the dollmaker is most likely responsible. She then takes it upon herself to save Neal from becoming a doll. [[spoiler: By extension, she ends up saving hundreds of other victims and puts a permanent end to the dollmaker once and for all.]]
* PoliceAreUseless: She tries to avert this by going straight to the police after learning what the dollmaker is doing. Unfortunately she doesn't get far.
* SiblingRivalry: With Neal. When she's not trying to stop him from ruining her dolls, she has to keep him out of trouble period.

!!'''Todd Barstow'''

The main protagonist of ''Go Eat Worms!'' An extreme worm enthusiast who gets more than he bargained for when his pets begin to turn against him.

* AssholeVictim: [[spoiler:Implied at the end, when a giant butterfly shows up, intending to skewer him with a pin for doing the same to other butterflies]].
* BigBrotherBully: He spends most of the first half of the book tormenting his sister Regina with worms. [[spoiler:At the end, it turns out that she was the one putting worms in his things, but she was still right about the worms wanting revenge]].
* SiblingRivalry: He competes with Regina in the school science fair and ends up sabotaging her project (a papier-mache robin) by stuffing worms in the beak.
* TookALevelInKindness: After Regina's robin saves him from a giant worm, he becomes much nicer to her and takes up butterfly-collecting. This is debatable though, since he still abuses animals. In the TV episode, he takes up fishing instead.
[[/folder]]

[[folder: Villains and Monsters A-M]]

!!Ahmed

A superstitious scientist who takes ancient curses a little too seriously in ''The Curse of the Mummy's Tomb''.

* AxCrazy: Anyone who violates the tomb is either ''mummified alive'', or thrown into a flaming tar pit.
* KnightOfCerebus: He's right up there with Mr. Toggle and the Lord High Executioner as one of the darkest villains in the series.
* ScrewThisImOuttaHere: When Gabe inadvertently brings all the mummies to life, they threaten to throw him into the tar pit, but he ends up booking it out of the pyramid instead.
* WouldHurtAChild: Even if you're a kid and stumble into the tomb by accident, he has access to tons of gruesome ways to kill you.

!!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.
* DeathEqualsRedemption: As his appearance in the end would suggest, it seems this horrifying fate made him into a much kinder person.
* DyingAsYourself:His mutilated soul haunted Hill House for years,basically a mindless husk of his living self. He finally becomes a full boy again after his head is found,and expresses his gratitude to the kids as he vanishes for good.
* 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.
* UndeathAlwaysEnds: He's ''already'' dead long before the story, but his spirit is finally laid to rest when the kids unearth his head. And if the Goosebumps wiki is to be believed, Seth, another character from the same book, will replace him in the upcoming movie.
* 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.

!!Aunt Dahlia

An old woman that makes a business of aging children into elderly people using special prune-based recipes, then sells them into marriage with her equally old friends. She gets away with this by passing herself off as a distant relative to different families, helped by [[ParentalObliviousness oblivious parents not asking questions]]. She is the villain of ''An Old Story''.

* AdultFear: She invades homes by pretending to be related to the family living there, and when she is left in charge of the kids, she mutates them and sells them into slavery. By the time the parents realize Dahlia was never related to them, it's too late.
* [[EvilUncle Evil Aunt]]: One who isn't even an actual relative to the kids she torments.
* LethalChef: Her food will turn you into an old person and can only be counteracted with baby food.
* NotQuiteDead: [[spoiler: The ending of the short story implies that, somehow, Dahlia survived being aged into dust and returned under a different name to bewitch another family.]]
* PlotRelevantAgeUp: Her whole shtick.
* RapeByProxy: The implications of her actions are that she is taking children, forcing them to ingest food that rapidly ages their bodies until they are old and feeble, and then sells them to her friends as a form of "marriage," which basically leaves said children too weak and feeble to understand what is going on or fight back as they are taken from their families and forced to live with depraved elderly men and women.
* RapidAging: Her cooking taken in liberal dosages will age a person over a couple of days, but being completely drenched in her prune juice turned her into dust in a few seconds.
* SlaveryIsASpecialKindOfEvil: She's a child slaver.

!!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.
* WorthyOpponent: Brutal as they are, they'll still treat you with respect if you prove to be the better player. Good luck with that,though. Ginger's victory came with sheer luck.

!!The Black Ring

An entirely black piece of jewelry home to an evil spirit. In ''Horrors of the Black Ring'', it is first found by Beth's homeroom teacher and makes her wreak havoc. When it's done using her as a host, the ring entices Beth to wear it and uses her. [[spoiler: Beth's sister Amanda buys an identical one.]]

* ClingyMacguffin: The only time it will willingly come off is when it's decided it's done with its current wearer.
* TheCorrupter: The ring's earliest influence has the wearer feel the need to commit random acts of evil for fun. But over time, as its influence grows, it will just flat out take over the wearer's body.
* DarkIsEvil: It's a completely black jewel set in a band of black gold.
* DemonicPossession: At first, the people who wear the ring are unaware they are being controlled, until the evil spirit inside the ring makes itself known and threatens to make them do far worse.
* EverythingsSparklyWithJewelry: And more evil as well.
* EvilFeelsGood: It makes its host do cruel and evil things. One third of the time, the host body is overwhelmed with feelings of joy as they commit these twisted acts. The other two thirds of the time, the host is horrified when they realize what they've done, and try to remove the ring, only for the ring to completely take over the host.
* ForTheEvulz: Why the spirit in the ring does anything it seems. It's never given a reason as to why it's so evil, it just is.
* NightmareFace: The ring's evil spirit usually manifests as a horrible looking face inside the ring's gem, which is sometimes passed off as a flaw.
* ThePowerOfHate: It fills Miss Gold with the desire to destroy the school fair and makes her kidnap Beth's sister. When the ring possesses Beth, it plays off her feelings of resentment to Anthony and her little sister Amanda by destroying the things they love.

!!'''The Blob That Ate Everyone'''

From, well, ''The Blob That Ate Everyone''. It's a giant, pink blob creature that devours everything in its path. Originally just a reoccurring character in Zackie Beauchamp's horror stories, the blob monster comes to life thanks to the magic typewriter Zackie found. [[spoiler: The blob monster is actually the writer of the story.]]

* AuthorAvatar: [[spoiler: The blob monster in the main story is one for the blob revealed to be ''writing'' the main story.]]
* TheBadGuyWins: [[spoiler: A friend of the blob monster suggests he change the ending so that Zackie and everyone else gets eaten.]]
* BlobMonster: [[SarcasmMode Who'd have thought?]]
* ExtremeOmnivore: It eats anything and everything in its way.
* KillEmAll: [[spoiler: In the new suggested ending, the blob is successful in eating everyone.]]
* YourMindMakesItReal: [[spoiler: Zackie figures out that ''he'' brought the blob to life, not the typewriter, and uses this power to think the blob out of existence and undo all the damage it did. This gets subverted when it turns out everything that occurred was being written ''by'' the blob.]]

!!'''Blue Monster Blood'''

A weird, blue variant of Monster Blood found by Andy in ''Monster Blood IV''. This version of the slime turns into small creatures that consume large amounts of water, and they aren't exactly picky about where they have to get it. After doing so, the creatures drink until they burst and multiple, and as they do so, they become increasingly aggressive. [[spoiler: They aren't actually Monster Blood. They were an underwater biological weapon developed by a group of scientists that went bad, and their creator disposed of the experiment's remains in an empty Monster Blood can.]]

* BlobMonster: Ones shaped like weird blue slugs with razor teeth.
* IAmNotWeasel: [[spoiler: The only reason Evan and Andy think these creatures are a form of Monster Blood is because they were found inside an old Monster Blood can.]]
* MixAndMatchCritters: They're like a cross between slugs, leeches, and bottom feeders made out of blue slime.
* MoreTeethThanTheOsmondFamily: They have razor sharp teeth which allows them to bite through anything, and they can also use them to latch on to people and animals so they can suck them dry.
* SelfDisposingVillain: When there are finally enough of them, the creatures will turn on each other and start to kill themselves in a manic frenzy before nothing is left.
* TookALevelInJerkass: The creatures are fairly tame and benevolent at first, but they more they multiply the angrier they get. [[spoiler: The same thing happens to Conan Barber after he eats some of the creature's residue, leading to Evan facing an army of angry Conans]].

!!'''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: They attempt this by "hugging" humans, then they somehow manage to crawl inside their bodies and take over.
* 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.
* FatBastard: She's considered a very large woman.
* ImAHumanitarian: After becoming a ghost, she hunts after those who summon her and/or don't eat her cooking with plans to chop them up and make lunch out of them. Although this is a subversion in the sense that it's never mentioned if she actually eats anyone, just that she's going to make lunch meat out of them.
* LethalChef: As mentioned, her culinary talents leave much to be desired. The whole reason she got her nickname was because of how badly kids reacted to her "Chinese Surprise" lunch.
* PunnyName: Sue Chopman's her actual name. When she's brought back, she calls herself "Aunt Sue."
* SayMyName: Saying it three times summons her. [[spoiler: And saying "Suey Chop" three times sends her away.]]
* StoutStrength: Judging by her hefty size and how easily she's able to chop things up with her cleaver.

!!Clarissa

A witch who was helped by Samantha Byrd one day, and as gratitude, offer to grant Samantha three wishes. Unfortunately, because Samantha didn't think them out clearly, and Clarissa's not as skilled at magic as she seems, these wishes tend to backfire badly. From ''Be Careful What You Wish For''.

* AdaptationalAttractiveness: Her level of beauty varies across the multiple formats she's appeared in. In the trading card art, she appears as heavyset. In the TV show, she seems to be in her late 40s and has a feathered black dress. In the early 2000s re-release, her appearance on the new cover for ''Be Careful What You Wish For'' seems to be a cross between the trading card art and the TV show. Finally, the artwork for the ''Classic Goosebumps'' covers and the art for the movie make Clarissa appear to be in her late 20s/early 30s, but she's also much more malevolent.
* AdaptationalVillainy: Appears to be portrayed as a straightforward villain in the upcoming movie.
* BecauseYouWereNiceToMe: The reason she is so insistent on granting Samantha's wishes is because Samantha helped her when Clarissa got lost, and also found a crystal that belonged to her.
* DarkIsEvil / DarkIsNotEvil: She zigzags these tropes. Clarissa dresses in black and while she isn't actively malevolent, her powers can make everyone on the planet disappear if someone made a careless wish.
* JackassGenie: To Judith in the TV show, but this comes across as a KickTheSonOfABitch moment. When Judith wishes that people from all over would come to admire her, Clarissa turns her into a beautiful statue.
* KickTheSonOfABitch: What she does to Judith in the TV show. In the book, she ends up turning Samantha into a bird when Judith says "Fly away, Byrd." But in the TV show she interprets Judith's wish to be admired by turning her into a statue. She also winks at Samantha just before this happens, implying she deliberately turned Judith's wish against her for the sake of helping Samantha.
* LiteralGenie: She'd be a JackassGenie, but the thing is Clarissa is actively trying to repay Samantha's kindness and warns her both that her powers aren't as refined as she'd like to admit ''and'' that Samantha has to think out her wishes clearly before she makes them.
* PetTheDog: To Samantha in the TV show.
* UnwantedAssistance: Samantha doesn't actually want her help, but Clarissa is insistent on repaying her debt, and it's easier to understand that Samantha only makes her other wishes they way she does A: Because she wants Clarissa to leave her alone, and B: She's scared and not thinking straight.

!!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.

* AffablyEvil: Aside from being a vampire, he is actually a pretty decent guy, and even saves Freddie's life at some point. Even when he promises to turn him and Cara into vampires, he doesn't seem to realize they don't see it as a good thing.
* BlueAndOrangeMorality: His idea of helping Freddie and Cara is to turn them into vampires so they can live along with him in the castle rather than just sending them back home.
* OurVampiresAreDifferent: Mostly follows the ClassicalMovieVampire archetype, with the only notable difference being that he needs to drink Vampire Breath in addition to blood.
* 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. Then again, [[BlueAndOrangeMorality he genuinely seems to believe that would be doing them a favor]].
* VillainousRescue: While in his castle, Freddie attempts to escape by a window, only to nearly fall to his death. Count Nightwing ends up saving him in bat form.
* 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's the only female member of the initial group of Creeps.

!!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. Though this makes at least some sense in that he was the one who messed with the clock in the first place.
* 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.
* TheCameo: It makes a five-second appearance in the TV episode ''The House Of No Return''.
* FeatheredFiend: The cuckoo bird, shown prominently on the cover. Turning it's head back triggers the clock's powers.
* ItCanThink: It forms some kind of psychic link to Michael as he goes backwards in time, and only makes things normal when he turns the bird head around. On the cover, it's outright ''glaring'' at you.
* MentalTimeTravel: Happens to anyone that twists the bird's head.
* TimeMachine: Not a very beneficial one, though.
* PetTheDog: If you believe it had any sentience or agency, then wiping Tara out of existence and thus vastly improving Michael's life may count.

!!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.
* BreakoutCharacter: Despite only appearing in one book, Cuddles became one of the most prominent of the monster characters featured in the 90s merchandise. However, he was DemotedToExtra when the franchise was revitalized with the ''Horrorland'' series, to the point that ''Monster Blood II'' has yet to be reprinted.
* ChildEater: It's implied that he was going to eat Conan before Evan stepped in.
* 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: They seem nice at first, but the children of Dark Falls enjoy messing with Amanda and Josh for no reason other than they feel like it, and once their true nature is revealed, they drop all pretenses of being nice in order to satisfy their hunger.
* CreepyChild: Karen and the rest of the Dark Falls children. They especially like to hide in Amanda and Josh' rooms while they sleep and fool around with their belongings. When they're not doing that, they like to randomly manifest in front of Amanda while she's alone and make her believe she's going crazy when they disappear. Josh mentions that there were a couple of boys in his room who were "mean" but Josh refuses to go into detail over [[NothingIsScarier what they did to him]].
* 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.
* {{Gaslighting}}: The children of Dark Falls make it a habit of screwing with Amanda and Josh. They'll randomly pop up in front of Amanda while she's alone, then disappear. They also like to mess with the siblings' belongings, and have tried to do things to them while they're asleep.
* 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.
* StarterVillain: The entire Goosebumps franchise began with these guys.
* TownWithADarkSecret: Dark Falls. With a name like that, it's no surprise.
* TheVirus: In their town, they'll welcome you as one of them-literally.
* UndeadChild: Ones that are a weird mix between vampires, zombies, and ghosts.
* 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.

!!Dorrie Morrow

A character from the Halloween-themed short story ''Bats About Bats''. Dorrie's a sweet girl who is ''very'' interested in bats. She plans to be a bat scientist like her parents when she grows up. [[spoiler: Literally.]]

* AntiVillain: [[spoiler: The only villainous thing she does is scare Liz and Suzanne by revealing her bat form, and even then the only thing that's implied about her actions is that she wants to scare them as payback for scaring her. That said, she's one of the least malicious monsters in the series.]]
* BewareTheNiceOnes: [[spoiler: She pays back her friends a scare for a scare.]]
* CollectorOfTheStrange: As the title indicates, she's bats about bats. She even has a stuffed teddy bat she sleeps with.
* CuteMonsterGirl: [[spoiler: Depending on how you see cute, but she can turn into a human sized bat, just like her family.]]
* FluffyTamer: She's able to calm down frantic bats and doesn't see it as anything strange.
* NiceGirl: She doesn't hold it against Liz and Suzanne that they think bats are creepy, but she also doesn't understand how anyone could ''not'' like bats. Though she does get mad at them when they hurt a bat that flew into her room. [[spoiler: Even when her true form is revealed, she doesn't even try to hurt or kill her friends. All she does is scare them.]]
* NonMaliciousMonster: [[spoiler: There's no indicator that Dorrie was ever going to do anything to her friends beyond freaking them out.]]
* WithFriendsLikeThese: She's incredibly hurt when Liz and Suzanne have Suzanne's brother scare her for the sake of proving that bats are creepy. Unusually for this series, the two regret what they've done when they realize Dorrie was really hurt.

!!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.]]
* BadPowersGoodPeople: He's a well-meaning father/botanist with a talent for growing ''human-plant abominations''. Better be careful introducing him to your first dates,Margaret and Casey...
* 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.

!!Dr. Maniac

A insane supervillain created by Robby Schwartz. Maniac frequently professes how crazy he is and works alongside a villainess called the Scarlet Starlet. His archenemy is another villain called the Purple Rage. [[spoiler: His backstory in Robby's webcomics is that he's Robby's fictional brother Sam, who became a supervillain because he felt overshadowed by Robby's achievements.]]

* AxCrazy: And proud of it.
* CardCarryingVillain: He never lets people forget that he's a MANIAC!
* Catchphrase: "I'm not (insert word), I'm a MANIAC!" As well "More (insert verb) than a (insert noun) in a (insert noun)." It's usually something completely stupid.
* MorallyAmbiguousDoctorate: Claims to have a degree in Maniacal Studies.
* PlatonicLifePartners: With his cohort the Scarlet Starlet.
* PsychopathicManchild: [[spoiler: Well considering he ''is'' a child...]]
* ThatManIsDead: [[spoiler: When his identity as Robby's brother is discovered, Maniac declares that Sam Schwartz doesn't exist anymore.]]
* TheUnfavorite: What drove him to become a villain.
* UsedToBeASweetKid: [[spoiler: Sam Schwartz used to be an average kid, until he finally got sick of being "the chubby joke" in his family and took on the persona of his brother's comic book creation.]]
* VillainTeamUp: With the Scarlet Starlet and even his worst enemy, the Purple Rage.

!!Emory Banyon
An award winning horror director, creator of the ''Scream School'' franchise, 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: Emory has a massive ego he's constantly feeding by scaring people and getting them to admit he's scared them. He keeps going after Jake because Jake refuses to give him the satisfaction.
* JustJokingJustification: His main justification for terrorizing Jake all the time.
* NightmareFetishist: From the way he enjoys inciting fear and terror into people in order to feel good about himself. He's not "The King of Horror" for nothing.
* 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.

!!Evil Camera

A camera capable of changing the future whenever it takes a picture, but the future it creates is always horrible. The main driving force behind the ''Say Cheese and Die!'' books, the camera ends up in the ownership of Greg Banks and later Julie Martin.

* BadFuture: Its specialty.
* BodyHorror: Some of the worst in the series. Besides the WeightWoe inflicted on Greg and Shari, which makes Greg so fat he can barely move and Shari so skinny she's practically just a skeleton, it made Julie's best friend Reena ''blind'' by doing something to her eyes akin to having chlorine or bleach thrown in your face, gave Becka and Greta horrific skin rashes, and mutated Julie's brother into growing fuzz and antennae on his head like a bee.
* FateWorseThanDeath: It makes Greg morbidly obese and Shari emaciated in ''Say Cheese and Die Again!'' in what is implied to be revenge for trying to destroy it.
* HappyFunBall: It simply looks like a unique camera, but it's pure evil.
* ItCanThink: It's implied the camera specifically chooses what horrible thing will happen to its victims, which explains why Greg and Shari's transformations in ''Say Cheese and Die Again!'' were so drawn out and horrible.
* {{Retcon}}: The camera was originally created by two evil scientists who planned to use it to make themselves rich but they backstabbed each other which is what led to the camera only taking evil photos. Then in ''Say Cheese and Die Screaming!'' the camera's backstory was altered so it was now a camera created for a horror film that never got finished because of unexplained accidents on the set. The film shared the title of the book, ''Say Cheese and Die Screaming!''
* SpookyPhotographs: The camera will cause bad things to happen to those who are photographed by it, ranging from simple accidents to car crashes.
* TookALevelInJerkass: Despite being more of a prop than a character, the camera somehow managed to become an even worse villain in its next two appearances by getting more creative with the BadFuture photos. BodyHorror and mutilation are a big factor in this.

!!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

* 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." And now,[[spoiler:the movie implies they'll be taking this to ''our world''!]]
* 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.
* DrivenToMadness: They slowly lost their minds over the decades they spent trapped in Greyworld, and only a handful of the kids managed to retain their sanity.
* KnightOfCerebus: Not only are they ''not'' hammy or campy antagonists, but the reveal of what they are turns ''The Haunted School'' into one of the darkest and tragic books in the entire franchise.
* 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.

* 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.]]
* ImprobablyCoolCar: How it first appears.
* MyCarHatesMe: Not only that, but it's actively trying to kill the rider as well.

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.]]
* ObviouslyEvil: In the 2015 film, the car appears with a license plate that says "Haunted."
* RedemptionEqualsDeath:[[spoiler: It's a rare unintentional example, but it's what prompts Mitchell to forgive her in the end.]]
* 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: If the mask is put on three times, it becomes permanently bonded to the wearer's face after the third time. The only thing that will get it off after that is a symbol of love, but even that's no guarantee it'll come off for good if it's worn again.
* 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.

!!Horrorland Horrors

The Horrors are a race of horned monsters who run the deadly theme park Horrorland. They make a sport out of tormenting humans with their dangerous rides, hidden behind jokes and puns to lull their victims into a false sense of security.

* AmusementParkOfDoom: Horrorland, which is actually the image for that page.
* TheBadGuyWins: [[spoiler: In the TV show. It's implied they actually kill the Morris Family by driving their car off a cliff.]]
* TheDragon: In the video game ''Escape From Horrorland'', the Horrors as a whole are this to Madison Storm who, in the game's continuity, is the actual creator of the park. In ''Goosebumps Horrorland'', [[spoiler: Byron is this to the Menace.]]
* EvilIsHammy: Oh so very much, especially in the TV show when the Morris Family is put through "Raw Deal" and the Horrors ''really'' get to show off how hammy they actually are.
* HeelFaceTurn: [[spoiler: Between the original books and ''Goosebumps Horrorland'', the Horrors seemed to have stopped actually killing humans and now just operate an actual theme park. But there are still some Horrors who ally themselves with bigger threats, and it hasn't stopped park management from hiring dangerous people like Jonathan Chiller.]]
* HeroicSacrifice: [[spoiler: The one good Horror who tried to save the Morrises from being eaten by Ripper dies so they can get away. Unfortunately, it doesn't do much good when it turns out their car is now being controlled by the other Horrors, making this a SenselessSacrifice.]]
* TheLeader: In ''One Day at Horrorland'' they were led by a female called the Horrorland MC, while in the video game they were led by Madison Storm. Another video game designated a Horror closely resembling a carnival barker and calling himself Horiffico as their leader.
* OurMonstersAreDifferent: They are a race onto themselves. The Horrors vary in terms of skin color and horn size, and some have human like features such as hair and breasts while others don't.
* TokenGoodTeammate: There was a random Horror who tried to warn the Morris Family to get out of the park while they could in ''One Day at Horrorland''. In the TV show, he actually saves them from being eaten alive by Ripper.
* TookALevelInKindness: During the ''Goosebumps Horrorland'' series, it would at first appear that the Horrors are the ones who've orchestrated the many villains to get their revenge on their child adversaries. [[spoiler: It's actually the Menace of Panic Park, alongside a small handful of Horrors, who're responsible for this, and in fact the Horrors themselves are actually ''trying'' to protect the kids. The Horrorland rides might still be terrifying and they ''are'' monsters, but it seems even the Menace was too much for them.]]
* WeaksauceWeakness: Being pinched. [[spoiler: Pinching a Horror makes them deflate like a balloon.]]
* WouldHarmAChild: In the first two Horrorland books, the TV show, and the video game. [[spoiler: The TV show especially points out among the belongings left by the families eaten by Ripper that there are children's toys and baby products. They also seem to actually kill Lizzy and Luke Morris along with their parents. Although in the ''Horrorland'' series, they no longer seem to operate like this.]]

!!Invisibility Mirror

A mysterious mirror found in the protagonists' attic in ''Let's Get Invisible!'' Whoever turns on the lamp at the top becomes invisible, but too much use may have some unforeseen side effects.

* AndIMustScream: [[spoiler:If you stay invisible too long, your reflection takes your place in the real world while you stay trapped in the mirror for eternity. It is more than implied that this is Lefty's ultimate fate.]]
* EvilTwin: [[spoiler:The reflections of the people who use the mirror. Their goal is to switch places and then force others into the mirror world.]]
* MagicMirror: A special variant of one that can make people invisible.
* SealedEvilInACan: The mirror is hidden behind a false wall in the attic, and rightfully so.

!!Jack-O'-Lanterns

Two mysterious ghouls with pumpkins for heads. In ''Attack of the Jack-O'-Lanterns'', they basically kidnap Drew Walker and her friends, forcing them to trick-or-treat for what might be forever before trying to convert them into pumpkinheads like them. They're also implied to be responsible for the deaths of four missing adults. [[spoiler: They're really Drew's friends Shane and Shanna, who were helping Drew prank her enemies Tabby and Lee for all the pranks they've pulled on her. The two are alien shapeshifters... and as they reveal to Drew before they leave, they ''did'' kill those four adults. Why? It was dinnertime.]]

* CoolAndUnusualPunishment: They make Drew, Walker, Tabby, and Lee trick-or-treat in a neighborhood that gives out huge amounts of candy, and then force them to continue against their will. [[spoiler: It's also possible that their allies handing out so much candy is also an attempt to subtly fatten up the four kids for a future meal, especially when the two ghouls force the kids to eat their candy so they have room to collect more.]]
* FatteningTheVictim: With the reveal that they eat plump humans, all the candy they force the kids to get comes across as one method of ensuring this.
* FauxAffablyEvil: [[spoiler: Friendship to humans does not exempt said humans from the possibility of becoming their dinner, and they have absolutely no issue with threatening Drew despite the fact that she has ''never'' done anything to them except be their friend.]]
* ForceFeeding: In order for the kids to have room for more candy, they make them eat what the already have, to the point of vomiting.
* ImAHumanitarian: Their preferred diet consists of well-fed humans. [[spoiler: And they warn Drew they don't make exceptions for friends if she doesn't watch what she eats.]]

* LosingYourHead: They can actually detach their pumpkin heads at will and makes others wear them.
* PlantPerson: They appear to be thus but are actually just shapeshifters.
* PlayingWithFire: The two main creatures show an ability to breathe fire.

He's the ArcVillain for the second ''Horrorland'' story arc, giving kids free souvenirs before they leave Horrorland, claiming he'll expect payment when he sees them again. After the kids have a horrible experience because of said souvenir, they're transported back to Horrorland where Chiller is waiting for them.

* {{Catchphrase}}: "Take a little Horror home with you."
* CollectorOfTheStrange: Just look at what he carries in his shop, including a magic dog tooth that grants unlimited wishes to a comic book that grants superpowers.
* DaddyIssues: He's got issues with both his parents. His mother kept him locked up in their house because she believed his mind was too special and had to protected away from people who wouldn't understand him, while his father thought he was an embarrassment and a sissy.
* EgomaniacHunter: As part of his DaddyIssues, he's desperate to prove to his late father that he can be a hunter.
* IJustWantToHaveFriends: He was so desperate for friends when he was a child that, as an adult, he made up his own. [[spoiler: Specifically, he made up Murder the Clown, Chef Belcher, Mondo the Magical, Madame Doom, Winner Taikall, and Seymour Winn-Doe. He was ''every adult'' the kids encountered before they entered his shop. Ray and the others get him to let them go home after they dress up as these characters and act as though they are abandoning Chiller.]]
* PsychopathicManchild: Has got severe childhood trauma and is incapable of making any actual emotional connection to other adults, which manifests by him "playing" disturbing and dangerous games with children.
* VillainousBreakdown: [[spoiler: When the kids dress up as his "friends" and say they're leaving him.]]
* VillainousCrossdresser: [[spoiler: He's revealed to be the version of Madame Doom Meg encountered in ''Weirdo Halloween''.]]
* WellDoneSonGuy: His father took him hunting one day when he was a child, but Jonathan messed up and literally shot himself in the foot with his crossbow. He's still trying to prove to his father that he can be a good hunter.

!!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.]]
* LaughablyEvil: His idea of fun is to torment and kill kids with deadly pranks.
* LovesTheSoundOfScreaming: As Todd screams for help, he tells him "Scream all you want my young boy, it's music to my ears."
* 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: In the sense that he's literally living in Marco's basement. [[spoiler: His mother does as well.]]
* 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.]]
* EvenBadMenLoveTheirMamas: He mockingly scolds Marco at one point for disobeying his mother. [[spoiler:After all, he still lives with his.]]
* HumanoidAbomination: [[spoiler: For starters, that thing on the cover is his true appearance. This isn't even mentioning that he can turn inside out while in human form.]]
* NonMaliciousMonster: [[spoiler:The real Keith is just as scared of Marco as vice-versa,and tries to avoid contact with humans.]]
* NotSoHarmlessVillain: A boy making statements about living in someone's basement doesn't seem quite as scary at first, but Keith later demonstrates he has enough strength to back up his demands and [[spoiler: almost kills Marco by smothering him in his blob form.]]
* SchrodingersButterfly:[[spoiler: He's the one dreaming the events of the book.]]
* WalkingSpoiler:He's definitely not the first example in the series,but he's certainly the most mind-boggling.

!!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.

* BlueAndOrangeMorality: He's literally been in a cave his whole life trying to survive,so naturally he knows nothing of human empathy and mercy.
* BerserkButton: Interfere with his constant bathing,and you're ''lunch.''
* ChildEater: He eats campers that try to take a break from washing him, and doesn't appear to live off of anything else.
* 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.
* 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.
* FreudianExcuse:He was born into his repulsive condition by careless humans,and is motivated by desperation to survive. It doesn't make him any less horrible, but it ''does'' explain why he's like that.
* 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.

!!The Marlings

A mysterious couple who live in a rundown home in Wolf Creek. Alex Hunter hears mysterious noises coming from their house, and begins investigating the possibility that the two are werewolves. He only has part of the truth. [[spoiler: There ''are'' no Marlings and there never have been. The house is abandoned except by those who use it to hide their werewolf skins. The real werewolves are none other than Alex's aunt and uncle.]]

* HeWhoMustNotBeSeen: The only people who've ever seen them appear to be Alex's aunt and uncle. [[spoiler: They're lying.]]
* TheGhost: They don't appear until halfway into the book, and even then [[spoiler: the werewolves Alex goes up against are really his aunt and uncle.]]
* LivingProp: [[spoiler: They were invented by Martha and Colin Hunter to act as a smokescreen for why strange noises were coming from the house next to them.]]
* OurWerewolvesAreDifferent: They, or rather [[spoiler: Martha and Colin]] are closer to the Skin Walker legend of Native American folklore, in that they shed their skins every morning.
* SecretIdentity: Of [[spoiler: Martha and Colin Hunter.]]

!!Mary-Ellen

A doll owned by Jillian's little sisters in ''Bride of the Living Dummy''. They take it everywhere they go, but they seem to be afraid of her and are always claiming that she does bad things. It turns out she's really alive and forces the girls to do things for her. And now she wants Slappy for a husband.

* CreepyDoll: She plays it straighter than Slappy in that she's an actual doll, not a dummy.
* EvilerThanThou: She's somehow even worse than Slappy in that she's been more successful in controlling young kids to do her bidding. Katie and Amanda are terrified of her, and in the TV show Katie explicitly tells Jillian that Mary-Ellen has threatened to kill her family if she didn't do what she wants.
* {{Expy}}: Of Tiffany from ''[[ChildsPlay Bride of Chucky]]''. She even sounds like her.
* UnholyMatrimony: What she wants with Slappy, but he's not interested.
* WomanScorned: When she finds out Slappy wants Jillian for his bride, she flips out and tries to kill him. What makes her especially mad, in the book at least, is that ''she'' was the one who revived him in the first place.

!!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.
* NotSoHarmlessVillain: What we see of his comics would have you believe he's just some campy weirdo. He proves otherwise in some truly horrifying ways.
* 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.
* VillainProtagonist: In-universe example. The comic books Skipper collects feature the Masked Mutant as the main focus of the stories.
* 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.
* WalkingSpoiler: He never makes a full appearance until the last four chapters, but his reveal puts the story in a much, much more disturbing context.
* WorthyOpponent: To a degree. He takes time to explain what's going on to Skipper so he won't die too confused.

!!Micah Brill

Wade Brill's sadistic older brother and just about everything that is wrong with her life. His abuse is so bad it drives Wade to seek the services of a company called ''Revenge R Us''.

* BigBrotherBully: He does whatever he can to embarrass Wade and make life difficult for her. He's also 5 years older than her and almost an adult himself. making his actions even more disgusting.
* ForTheEvulz: Micah is never given a reason why he loves tormenting Wade other than he can. In fact, [[spoiler: when he found out Wade was going to Iris to get revenge, he paid Iris $300 to not only make sure Wade's attempts failed, but that they would also backfire on her. Why? Because he felt like it.]]
* HateSink: What makes Micah especially infuriating is that, when Wade finally does get revenge on him it ''still'' backfires on her, almost as if the book is saying she deserves this for wanting to fight back against his abuse. Which in turn means Micah's horrible behavior is being ''validated''.
* LaserGuidedKarma: [[spoiler: While the book does end with Micah being turned into a frog, Wade herself is also turned into one so the karma aspect is subverted.]]
* TeensAreMonsters: Oddly enough for this series he doesn't turn out to be an actual monster even though he is legitimately a terrible person.

!!Monster Blood

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

* AttackOfThe50FootWhatever: What results from it's consumption.
%%* BlobMonster
* ExtremeOmnivore: It will devour everything that comes in contact with it, and doesn't discriminate between kids, animals, or even [[spoiler: its master Sarabeth]].
* GenericDoomsdayVillain: This is to be expected, since it's a mindless lifeform, but it's creator, [[spoiler: Sarabeth]], is a more straightforward example. [[spoiler: 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: If Monster Blood is eaten, it will make the consumer grow to horrible proportions, but the effects vary. When eaten by Cuddles and Evan, it makes them grow big, but when eaten by Matt in ''Monster Blood For Breakfast!'' it causes him to undergo severe BodyHorror as his muscles swell and he becomes an inhuman lump.
* 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.

* AntiVillain: Although he tries to kill Lucy (and probably anyone else who finds out his secret), he's still mostly a monster who wants to live his life peacefully and isn't above harming children to protect himself.
* 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.

* AndIMustScream: His fate at the end of "Piano Lessons can be Murder," is spending eternity perfecting the piano in the basement of the music school.
* AssholeVictim: One of the most ''depraved'' villains in the entire franchise, and his final fate is implied to be equally horrible.
* 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.
* TheDogBitesBack: Dragged to his death by the hands of the students he harvested and enslaved. School reunions can be a pain, eh, Toggle?
* 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.
* HelpingHands: Creates these out of the bodies of his victims. They ''do'' end up being helpful, but certainly not in the way he wanted.
* KnightOfCerebus: He's a serial killer with one of the highest bodycounts in the entire series. [[SarcasmMode Kid friendly scares, amirite?]]
* 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.
* PoweredByAForsakenChild: Uses all the hands he steals to form the ultimate piano concerto.
* 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!"
* RidiculouslyHumanRobots: Dr. Shreek, again, and several other "instructors" Jerry sees around the school. Not human enough, apparently, and that's where the students come in...
* 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.

!!Mr. Wood

The original living dummy from early in the series. Mr. Wood was given to Kris after her sister Lindy found Slappy, and he was the one who initially came to life and tormented the girls. He was killed off in the book's ending and hasn't appeared since in any of the other books since.

!!Mrs. Boren

Sam's babysitters from ''Nutcracker Nightmare'' whom she loathes. She used to look after Sam when she was younger, and Sam claims she was never allowed to do anything fun, to the point that she calls her "Ol' Boring." She invites Sam's family to a showing of ''TheNutcracker'', and decides to teach Sam a lesson about patience when Sam says she's about to be "Bored to death."

* BabysitterFromHell: Subverted in that, while she was strict when she ''was'' Sam's babysitter, she doesn't reveal how bad she actually is until after she's formally stopped looking after Sam.
* TheBore: To Sam, hence her nickname.
* DisproportionateRetribution: Okay so yes, Sam was being a bit of a brat, but in hindsight it's clear she didn't want to go with her parents to the ballet because she had an unpleasant history with this woman. And if she wanted to torment Sam into learning what boredom is, she didn't necessarily have to drag everybody else into it.
* EmbarrassingNickname: "Ol' Boring."
* MindRape: It's not clear if everyone in the audience ''was'' getting older or if this is just what Boren made only Sam see.
* NothingIsScarier: The story ends as Boren reminds Sam, who has aged several years by this point, that there's still a second act in the ballet to get through. One can only imagine just how badly things get from that point.
* SoftSpokenSadist: In her effort to terrorize Sam into learning patience, the spell she cast may not live others aware of what's happening but it still effects them. Sam can see that her mother is aging and so is pretty much everyone else in the audience. She also frequently tells Sam, as sweetly as she can, that if she wants the ballet to be over, she'll simply have to be patient.
* TimeMaster: She has the power to manipulate the passage of time. In order to show Sam what ''real'' boredom is, she casts a spell that makes the ballet drag on for so long that, by the end of the first act, Sam has grown out of the dress that was originally too big for her. She also makes it impossible for Sam to leave the theater, and Sam is the only one besides Boren who is aware of what's going on.

* CoveredInMud: They ''are'' mud.

* SignificantAnagram: Norband is another way to spell [[spoiler: Brandon]].
* YankTheDogsChain: [[spoiler: He tells Brandon he can come back to life if he can save three scared people. When Brandon manages to do just that, Norband tells him "Oops, just joking!"

* AntiVillain: One of the more benign creatures in the series, he just wants to be in a play so he can rest in peace.
* CoolMask: The cover art for the book depicts it as just a plain white mask, but the book describe's the Phantom's mask as actually being blue-green. The UK cover artwork is a closer example of what the mask is described as.

It's not until opening night that the ''real'' Phantom shows up.]]

* TragicMonster: They died before they could have a chance to actually live life in the new world, and now they're stuck haunting the beach where they died. All they want is some new companionship no matter how they have to get it, and they're consistently stalked and terrified by a man who wants to destroy them.

* CreepyDoll: Sweet Sue, a lovable baby doll that is actually a serial killer from Mars.

* SerialKiller: The Mad Mangler, whose modus operandi is that he'll mangle any unsuspecting fool that walks by the lot he inhabits.

!!'''Slappy'''
[[quoteright:158:http://static.tvtropes.org/pmwiki/pub/images/rsz_1slappy_the_dummy2_by_wicker123_916.jpg]]
-->''Voiced by: Cathal J. Dodd (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.

!!The Snatcher

It feeds off a new camper every summer, but said camper is usually chosen as a representative to finally destroy the creature for good.

* ChildEater: One who specifically only eats a single camper every summer.
* EvilIsPetty: Eating children isn't enough for it. as the Snatcher keeps the spirits of those it feeds on trapped at Camp Full Moon. The reason a new camper is selected every year is so the campers will have someone to fight for them so they can be free.
* FantasticFoxes: It takes on the form of a fox, but whether or not it actually ''is'' a fox or just assumes the form because of the many foxes that live in the woods surrounding the camp is unknown.
* FlunkyBoss: The Snatcher seems to have some form of control over monsters who live in the river. Those who try to swim across get dragged under by ghastly green, rotted hands. [[spoiler: The monsters turn on the Snatcher when Dustin gets to the other side. When it falls in the river, they pull it under. It's entirely possible ''they'' were the ones in control and the Snatcher served them.]]
* ManipulativeBastard: [[spoiler: It takes on the form of a girl called Laura and tries tricking Dustin into believing she's from a nearby girls camp. This is all to get him into the river so she can kill him, but she blows her disguise when she gets tired of waiting.]]
* NothingIsScarier: Like the villains of the original ''Ghost Camp'', the Snatcher's backstory is shrouded in mystery. There's no explanation given to where it came from or why it only hunts one person a year. [[spoiler: There's the possibility that the creatures living in the river are actually ''its'' masters instead of the other way around, with the Snatcher bringing them new victims every year. Considering they tore the Snatcher apart when Dustin got to the other side, it's quite possible this was a case of YouHaveFailedMe.]]
* OurMonstersAreDifferent: There are a set of rules when dealing with the Snatcher. It will only select one camper every year, and if that camper is able to cross the Snatcher's river to the other side the Snatcher will be defeated.
* PronounTrouble: [[spoiler: It disguises itself as a young girl, but the book doesn't clarify if the Snatcher really is female or simply took the form of one.]]

* GoneHorriblyWrong: It was created by accident thanks to the reckless spell casting of a pair of sorcerers.
* LukeIAmYourFather: It tries to convince Jaclyn that he is really her father, trapped in the snowman form by accident thanks to her mother and aunt. [[spoiler: Unfortunately, because Jaclyn had begun to distrust her aunt ever since they moved to Sherpia, she believes the snowman and frees him.]]
* ManipulativeBastard: It plays off the distrust Jaclyn has developed with her stern Aunt Greta and gets her to seriously consider that it might be her DisappearedDad. [[spoiler: When she does free it, the Snowman decides to get rid of her.]]
* OneWingedAngel: The Snowman's current appearance is not it's true form. [[spoiler: After Jaclyn is tricked into freeing it, we find out its true form is like that of a Minotaur with red, crusty scales.]]
* {{Snowlems}}: Version III.
* UngratefulBastard: [[spoiler: It still tries to kill Jaclyn even after she frees it.]]
* WasOnceAMan: It claims to be Jaclyn's father. [[spoiler: It's not.]]
* YouHaveOutlivedYourUsefulness: [[spoiler: Its thanks to Jaclyn is that it will now kill her.]]

* AssimilationPlot: Prolonged viewing of the video tape gradually makes the viewer turn into Susie Snowflake. They become obsessed with baking, their hair turns red and curly, and their disposition becomes disgustingly sweet.
* BrightIsNotGood: She's all Christmas colors and Christmas cheer, but she's pure evil.
* {{Catchphrase}}: "Pretty please with Christmas trees!"
* HappyFunBall: She seems cute and happy, but she's basically a mind raping virus that overwrites and possesses viewers into becoming carbon copies of herself.
* KillItWithFire: [[spoiler: The only way to stop the possession is to destroy the video tape, which Beth accomplishes by throwing it in the fire.]]
* MindRape: It's shown that victims gradually have their identities and emotions overwritten by the video tape, so that by the time they can finally act, it's too late. [[spoiler: Although Beth is briefly able to snap out of it by seeing her favorite wrestler on TV.]]
* PluckyGirl: In her movie, she goes around spreading Christmas cheer everywhere she goes.
* SealedEvilInACan: In a video tape.
* SugaryMalice: The video tape brainwashes people into becoming baking obsessed, redheaded airheads who'll do nothing but watch ''A Holly Jolly Holiday'' over and over again.
* TastesLikeDiabetes: Invoked in-universe. She's enough to rot all your teeth in one setting.

!!Tara Webster

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

* EnfantTerrible: She's tormented her brother ever since she was a baby. The fact that her terrible behavior started out from the time she was an actual infant shows there is something ''really'' wrong with this girl.
* ForTheEvulz: She torments her brother simply because she enjoys making him miserable.
* InSeriesNickname: "Tara the Terrible".
* [[ManipulativeBastard Manipulative Bitch]]: Not just towards her parents, but pretty much everyone except Michael are incapable of thinking she could do anything wrong and she milks it for all it's worth to make Michael suffer.

* 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.

* AttackOfThe50FootWhatever: [[spoiler:The giant worm that lives under the softball diamond and attacks Todd at the end]].
* ItCanThink: After Todd cuts a worm in half, his other worms poke their heads up, as if staring at him angrily. Afterwards, worms start showing up everywhere, and Todd begins to think they're getting back at him. [[spoiler:He's half-right: Regina put the worms everywhere as a prank, but there is one worm (see above) that ''does'' want revenge]].
* MamaBear: "This is the mother worm. She's coming up to protect her babies."
* MistakenForQuake: [[spoiler:The giant worm causes the softball diamond to shake when it begins to surface]].

!!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

!!The Unloved

The formal name for the masks created by the Shopkeeper in ''The Haunted Mask''. Much like the Haunted Mask, these were created as synthetic faces that sadly became warped and deformed shortly after they were finished. The masks are alive and yearn for someone to wear and want them. Other than the Haunted Mask, the only other masks to be featured were an old man mask worn by Steve Boswell and a purple ghoul mask worn by [[spoiler: Steve's friend Chuck.]]

* AdaptationalAttractiveness: The grotesqueness of the masks varies from format to format. In the books many of them are described as having certain animalistic features, while in the TV show they appear as warped and malevolent exaggerations of human faces and in the trading card series they appear very cartoonish.
* EarnYourHappyEnding: [[spoiler: The old man mask actually gets the chance to live without hurting anyone when the kids discover that there's a body it can be attached to. The mask becomes the body's head, awakens, and happily leaves to live a life on its own. This is only in the book version of ''The Haunted Mask II'', as in the TV show it gets destroyed.]]
* KilledOffForReal: The TV adaption of ''The Haunted Mask II'' opens with the Shopkeeper destroying the rest of the masks, but the old man mask is spared from destruction due to the arrival of the Haunted Mask.
* IJustWantToBeLoved: They even briefly come alive at one point and chase after Carly-Beth, begging her to love and want them.
* TragicMonster: Even more than the Haunted Mask, as these masks plea for someone to just want them and aren't as destructive as the Haunted Mask.
* WhatHappenedToTheMouse: They disappear save for two in ''The Haunted Mask II'' and in the other sequels they're just not mentioned at all.

!!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.

* BerserkButton: Don't ever be disrespectful or show bad manners around her. Seriously, don't. Don't. '''DON'T.'''
* 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.
* FauxAffablyEvil: She laughs at Crystal and Cole's predicament as they try to get her attention only after they've fully turned into chickens. And then she "sadly" states she can't do anything now, even if they apologize. [[spoiler: This turns out to be a complete lie, as it takes Crystal writing a ''thank you note'' for trying to teach her and her brother manners for Vanessa to undo the spell in a few seconds. She then curses them again when they belch without saying "Excuse me."]]
* HarmfulToMinors: Crystal and Cole are implied to not be her only victims.
* 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.]]
* KnightOfCerebus: So ''Chicken Chicken'' is a book about a couple of kids who're slowly turning into chickens. Sounds like another goofy entry in the ''Goosebumps'' franchise. That is until we see just how horribly slow and painful Crystal and Cole's transformations are, how their lives are ruined, and how Vanessa takes so much pleasure in seeing them suffer there's no longer anything funny about this book. And all because they made her drop her groceries and didn't apologize.
* WickedWitch: One obsessed with good manners.
* WouldHarmAChild: She subjects them to horrific torture for the slightest trouble.

!!Will Blake/Werewolf of Fever Swamp

A streetwise local boy from Fever Swamp, California, and the first in a ''long'' line of werewolves to appear in the franchise. Recently,his werewolf form is appearing in the upcoming movie.

* AmbiguouslyBrown: He has vaguely Hispanic features in the graphic adaptation.
* ArbitrarySkepticism: He frequently scoffs at the notion of werewolves,even when his friends are suspecting the Swamp Hermit. This could imply either he's trying to keep his secret as much as possible, or he's deeply ashamed of what he is.
* CompositeCharacter: In the TV episode it's him,not Cassie,who is obsessed with werewolves and accuses the Hermit.
* DyingAsYourself: Sadly subverted. In the TV episode, he reverts partially to human form long enough to warn Grady...and than changes back before Wolf kills him.
* NiceGuy: As a human,anyway.
* ParentalAbandonment: Earlier in the book,he mentions his Dad telling him the story of Fever Swamp. When Mr. Tucker pays his home a visit, it's completely empty.
* PoisonousFriend: Grady gets along very well with him. Will kills his family's deer,frames his dog, and tries to kill Grady himself as a werewolf.
* TragicMonster:We don't know just how much agency he has as a wolf,but he does seem to avoid attacking people in homes,and begs Grady to stay back after changing back in the episode.
* OurWerewolvesAreDifferent: A kid wolf.
* TheWorfEffect: In his book appearance, he gets fought off by ''Grady's dog''.[[spoiler:And in the movie trailer,he gets owned by a nerd with a silver tooth filling.]] Definitely not cut out to be a werewolf.

!!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]]

!!'''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.]]

!!Ari Davis

An athletic kid who enjoys pulling practical jokes, he convinces Dustin Minium to switch identities as a gag when they arrive at Camp Full Moon in ''Return to Ghost Camp''. The truth is, Ari was selected to be the camp's yearly sacrifice to the Snatcher and used Dustin as a patsy.

* BitchInSheepsClothing: He acts chummy with Dustin when they first meet in order to get him to play along with the "joke." When Dustin finds out the truth, Ari brings out his asshole side and refuses to come clean.
* TheChosenOne: He was selected by Camp Full Moon to fight the Snatcher, but tricked Dustin into giving him his identity.
* DirtyCoward: It ''is'' understandable that he wouldn't want to fight against a ghost since he didn't have a say in the matter, but he specifically picked a kid who was much weaker than him to take his place and threatened the kid's little brother to keep his mouth shut or he'd hurt him. [[spoiler: We then find out that to beat the Snatcher, all he had to do was cross a river using a low hanging tree branch, which would've been a snap for him because he's a gymnast.]]
* FauxAffablyEvil: Even after Dustin finds out Ari used him to get out of fighting the Snatcher, he still tries to act friendly with him. The friendly part disappears when he not only mocks Dustin over the switch, he stops Dustin from trying to call his parents to go home and threatens Dustin's younger brother if he doesn't lie.

!!'''Carla'''

A superstitious girl from ''The Thumbprint of Doom''. She tries to warn the kids in her new neighborhood whenever they're about to do something she sees as unlucky, and they quickly grow annoyed with her.

* AmbiguouslyBrown: She's described as having olive colored skin.
* EvilAllAlong: The kids try to scare Carla by paying a fortune teller at the local carnival to give her the "Thumbprint of Doom." However, Carla reveals she knew it was a joke, because only ''she'' has that power, revealing the reason why she is so superstitious is because she's a witch. She then gives the other kids the actual Thumbprint of Doom, marking them for death. [[spoiler: Except she doesn't actually have powers. Carla just pulled a joke on them as payback because the fortune teller they paid to trick her, Madame Wanda, is her mother.]]
* NotSoHarmless: [[spoiler: Carla's one of a few characters who manages to circumvent the usual "nasty prank done by friends" plot used so often in these books. Trisha and the others pay Madame Wanda, a fortune teller working at a nearby carnival, to pretend to give Carla the Thumbprint of Doom she fears. What they didn't count on was that Madame Wanda is Carla's mom, and told her what happened. So Carla staged a little prank of her own.]]
* ThirteenIsUnlucky: She stopped a girl from a hitting a home run because it was thirteen minutes after one in the afternoon, which made the time 13:13.
* WellIntentionedExtremist: She legitimately thinks she's helping people by warning them against doing something unlucky, and doesn't see it as annoying.
* [[WhyDidItHaveToBeSnakes Why Did It Have To Be The Thumbprint Of Doom?]]: The one thing she fears above all her other superstitions is the Thumbprint of Doom. If someone marks it on someone's forehead, something horrible will happen to them in 24 hours.
* WithFriendsLikeThese: Subverted. Trisha and her friends are genuinely annoyed at how Carla's beliefs can be aggravating, but they do some to actually like her. The prank they set up isn't to get rid of her, but to make her see her superstitious behavior is foolish. Of course, Trisha and the others prove they're also susceptible to acting foolish.

!!'''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''.
* ParodySue: Her ability to excel in everything she ever attempts seems deliberate just for the sake of having Eddie and his friends hate her.

!!'''Danger Inc. Kids'''

Three kids named Robbie, Lori, and Nathan, who claim to be the boldest kids in the neighborhood and are looking for a fourth member.

* AssholeVictim: The episode ends with them being trapped in the House of No Return with the ghostly couple...FOREVER.
* LaserGuidedKarma: They force Chris to spend an hour in the house as an initiation into their club. When the hour's up and they go inside to get him, they encounter two ghosts who inform them that [[spoiler:they let Chris escape because he promised that if they did, three other kids would take his place]].
* PowerTrio: One that is desperately trying to become a FourManBand.

!!'''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 Galloping Gazelle

The Masked Mutant's arch-nemesis.

* BigGood: He's the leader of the League of Good Guys, an organization of superheroes determined to stop the Masked Mutant.
* DirtyCoward: After the Masked Mutant kicks his ass, he simply ditches Skipper and leaves him at the Mutant's mercy. Skipper laments that he should call himself the Galloping Chicken instead.
* ScrewThisImOuttaHere: "I'm too old for this superhero stuff. You're on your own, kid!"

!!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.

* BadassGrandpa: Holing up in a cave to hunt murderous ghosts[[spoiler:and sealing yourself away to stop them]] certainly earns you points.
* CoolOldGuy: If he wasn't such a fanatic,he'd be a better example.
* DarkIsNotEvil: Living for God knows how long in a cave isn't good for appearances.
* HeWhoFightsMonsters: So much so that he's willing to use two innocent kids as bait for a ghost trap.
* PickOnSomeoneYourOwnSize: The Sadler spirits may be hundreds of years old,but spiritually they're still kids,and it's implied they're even more afraid of him than the other way around.
* TakingYouWithMe:[[spoiler:Buries himself and the ghosts in a cave in to stop them once and for all.]]

!!'''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.
* GoneHorriblyWrong: His experiments to regain his looks could not have gone worse.
* 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.

!!Thalia Halpert-Rodis

A student at Bell Valley Middle School who becomes friends with Tommy Frazier. Thalia gets picked on because she wears a lot of make-up, to the point that she nearly has a nervous breakdown when someone steals her lipstick. [[spoiler: She was part of the original Bell Valley Middle School class of 1947, the one sent into Greyworld by Mr. Chameleon. Thalia was one of a few who retained their sanity, and discovered by accident a way to escape back into the color world, only she is now permanently gray.]]

* BerserkButton: Don't ever try to steal her lipstick or her make-up.
* BrokenBird: [[spoiler: While she stayed sane after all those years, she feels so out of touch with the modern world she'd rather spend the rest of her life trapped in a colorless, photo-like dimension with the rest of her friends.]]
* ChekovsGun: Her lipstick. [[spoiler: When she was still in Greyworld, she discovered that a lipstick tube buried in her purse somehow retained its color. She started drawing with it and was shocked to see the color had eaten away at the walls and opened a portal back to the real world. Thalia went through, but the hole closed up before she could get her friends. When she makes it back to Greyworld, she uses the lipstick to help Tommy and Ben escape.]]
* GoingNative: [[spoiler: The stress of constantly hiding her gray visage, being constantly picked on by the other kids because of her "obsession" with make-up, and just generally feeling out of place because of how different the world is makes Thalia realize the only place she belongs now is Greyworld.]]
* IChooseToStay: [[spoiler: After helping Tommy and Ben return to the color world, she stays behind because she doesn't think she belongs outside of Grayworld anymore. The rest of her friends end up realizing the same is said for them.]]
* LockedIntoStrangeness: [[spoiler: She's completely gray, and wears so much make-up to hide her gray skin and hair. Like the rest of the class, being in Grayworld stopped her physical growth.]]
* OlderThanTheyLook: [[spoiler: She should be in her sixties by now, considering she was a member of the 1947 class.]]
* UncannyValleyMakeUp: She wears so much of it that this is the end result.
* WalkingSpoiler: Unlike most examples in Goosebumps canon though, [[spoiler:she's not the villain.]]
