[[folder: Notable Protagonists]]
!!'''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.

%%* BigBrotherInstinct: Toward Sheena.

%%* CheerfulChild
* 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.
* StrawLoser: Averted. Billy avoids most of the characteristics that the other protagonists have.

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

%%* BeCarefulWhatYouWishFor

* [[OnlySaneMan Only Sane Girl]]: In the Horrorland series, she soon becomes the most levelheaded member of the group.

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

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

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

[[folder: Villains and Monsters]]

* 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.

%%* CreepyChild: Obviously.
* AFateWorseThanDeath: Little Karen Somerset (and presumably other residents) thinks this way of her undead existence.

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

!!Della Raver

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

%%* AntiVillain
* 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
* DespairEventHorizon: After Sarah makes her refusal clear, Della wails in misery and sinks into the ground.
* ManipulativeBitch: [[spoiler: Pulls off a vicious gambit where she makes Sarah terrified of the water by pretending to have drowned, so that she can find her when she least suspects it.]]
* IJustWantToHaveFriends: More specifically, she wants a "buddy" to join her in the afterlife.
* TragicVillain: Unlike many other antagonists, Della clearly resents being a monster and will do anything to escape it.
%%* UsedToBeASweetKid
* WoobieDestroyerOfWorlds: Arguably the most clear cut example in the entire franchise.
* {{Yandere}}: Brushing off her affections is a ''very'' bad idea.

!!Dr. Brewer

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

%%* AntiVillain: Brewer himself is a type V. [[spoiler:His clone is more a type II.]]
* TheAtoner: By the end of the book, he gives up his horrible experiments and tries hard to make up to his family. [[spoiler:Or so it seems.]]
* BodyHorror: His mutation into a plant creature. And lets not even talk about the the things he grows in the basement...
* CreepyBasement: His lab. The book is called "Stay Out Of the Basement" for a reason.
* CloningBlues: His clone held him hostage in a basement for weeks and tried to take over his life.
* DudeWheresMyRespect: To his boss for firing him.
%%* EvilutionaryBiologist
* EvenEvilHasLovedOnes: He loves his kids, Margaret and Casey.
* 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.
* 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.
* 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.

!!Haunted Mask

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

* AscendedExtra: In the book ''The Haunted Mask II'', the Mask wasn't featured at all. In the television adaption, the Mask is added to the plot as the main villain, possessing the shopkeeper and turning Steve into his minion for the sake of getting to Carly Beth and possessing her again.
* BackFromTheDead: In the television adaption of ''The Haunted Mask II''.
%%* ClingyCostume
%%* ClingyMacguffin
* 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.
%%* IJustWantToBeLoved
* 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.

!!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
* 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.
* WouldHurtAChild: And won't let anything stop him.

!!Masked Mutant

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

* ActuallyADoombot: The Mutant encountered by Skipper and the Galloping Gazelle is actually a henchman with similar shape-shifting abilities. He's killed by the real deal.
%%* AffablyEvil
* ApologeticAttacker: As evil as he is, he does apologize to Skipper before attempting to kill him, as if he feels he has no choice.
%%* BadAss
%%* 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
* 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
* EvilRedhead: As "Libby", his human guise.
* ForTheEvulz: The reason why he kills his henchman.
%%* GeniusBruiser
%%* HoistByHisOwnPetard
* 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.
* 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.
* PunchClockVillain: The whole point of his existence is to be the perfect villain for his target audience. Then again, he seems to really ''enjoy'' his job.
* ShapeshiftingSeducer: Tries to gain Skipper's trust in the form of ''an attractive young girl'' named Libby. Thankfully, this remains strictly platonic.
* ShapeshifterDefaultForm: A towering figure with a purple mask and cape. However, we never see him unmasked, and it's not even clear if this is his true form.
%%* TooDumbToLive
* TrickingTheShapeshifter: How Skipper takes him down.
* TheOnlyOneAllowedToDefeatYou: Kills his henchman for trying to finish off Skipper before him.
%%* VoluntaryShapeShifting
* VictoryIsBoring: Apparently his motive for targeting Skipper. He was always one step ahead of the heroes in his world, and in his opinion, the kid was the only one who would provide a challenge.
* TheWorfEffect: By way of a twelve year old.
* WorthyOpponent: To a degree. He takes time to explain what's going on to Skipper so he won't die too confused.

!!Mr. Mortman

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

* BaldOfEvil: He's described as having male-pattern baldness, and appears this way in the TV episode as well.
* 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.

!!Monster Blood

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

* AttackOfThe50FootWhatever: What results from it's consumption.
%%* BlobMonster
%%* ExtremeOmnivore
* GRatedDrug: Although it's not treated like one, a formula that causes massive growth would probably be the ultimate performance enhancer.
* GenericDoomsdayVillain: This is to be expected, since it's a mindless lifeform, but it's creator, Sarabeth, is a more straightforward example. Other than wanting to keep Evan's aunt as a slave, she has no personality or motivation whatsoever, and is simply in the story to provide an explanation for the ever growing slime.
%%* HungryMenace
%%* MutagenicGoo
* SealedEvilInACan: And some sap always winds up opening it...
* SeriesMascot: It forms the title of the series.

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

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

* AscendedExtra: Didn't come to life until the very end of ''Night of the Living Dummy'', after the heroes destroyed the main antagonist, Mr. Wood. The sequels obviously focus on Slappy, though he occasionally shares the spotlight with other dummies.
* 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.
* {{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.
%%* 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
* 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.

!!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
%%* BitchInSheepsClothing
* DrillSergeantNasty: He doesn't even hire a nurse at his camp because he doesn't believe in "pampering" his boys.
* HumanAlien: Revealed to be this in the twist(along with everyone else at the camp).
%%* JerkassFacade
%%* PunchClockVillain
* SecretTestOfCharacter: The entire plot is revealed to be this for Billy.
* ScoobyDooHoax: He, along with all the other campers, invented a monster that's said to live in the forbidden bunk.
%%* TrainingFromHell
%%* WalkingSpoiler
* WellIntentionedExtremist: He's actually a nice guy who wants to ensure his campers' success, it's just that his methods are extremely dangerous and unethical.

!!The Beasts

A race of ferocious bear/possum hybrids who play a bizarre game with their victims to choose who gets eaten.

!!Karl

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.
* 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.

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

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

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

!!'''The Shopkeeper'''

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

* AdaptationExpansion: In the TV episode of ''The Haunted Mask II'' he has a greatly expanded role, wherein he gets [[GrandTheftMe taken over]] by the original Haunted Mask.
* AllThereInTheManual: His backstory is provided in the ''Goosebumps Collector's Caps Book'', wherein it's revealed he was injured in a high school chemistry accident, leading him to begin creating the masks.
* 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.
* ReedRichardsIsUseless: The masks he creates are amazing scientific achievements, and the science behind their creation could've been used to much better ends; the pioneering this guy did in growing artificial, lifelike faces would have ended disfigurement, had he taken the time to publish his discoveries.

!!'''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
%%* BlondGuysAreEvil
%%* {{Greed}}
%%* HumansAreTheRealMonsters
* 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
%%* ReasonableAuthorityFigure: [[spoiler:Subverted.]]
