Characters who debut in other Goosebumps media, such as the films, TV series and comics.
A hammy and unscrupulous magician and rival of Amaz-O, who trapped him in the form of a rabbit some time prior to the events of Bad Hare Day. While he has no counterpart in the story that the episode is based on, he may have been inspired by Amaz-O's unseen rival, Frank.
- The Bad Guy Wins: He turns Tim and Amaz-O into rabbits, though this admittedly does not appear to bother Tim.
- Fauxreigner: Has a Latin theme, despite appearing to be Caucasian.
- Jerkass: Nearly every word that spills out of his mouth is an insult or some kind of condescending remark.
Curtis and Julia
Schoolmates of Conan Barber who Evan Ross meets during his flight to Atlanta in More Monster Blood. Julia is a pretty rich girl with an interest in art, while Curtis is a sickly geek who may have been based on the novel character Kermit Majors.
A moneygrubbing girl who discovers Karlsville hidden away in her attic in Chillogy, Part I: Squeal of Fortune. After narrowly escaping from the tiny town, she changes her ways, and later helps Matthew Erickson save his younger brother, Todd, from Karlsville in Chillogy, Part III: Escape from Karlsville.
Matthew and Todd Erickson
Brothers who take possession of Karlsville after it is thrown out by Jessica Walters. Matthew is the older brother and a wannabe baseball star, while Todd is obsessed with winning, personality traits which are exploited by Karl Knave in Chillogy, Part II: Strike Three... You're Doomed and Chillogy, Part III: Escape from Karlsville.
The sinister mayor of Karlsville from the three-part Chillogy episode.
- Canon Foreigner: His story is completely exclusive to the TV series.
- Corrupt Politician: Subverted. He's officially the "mayor" of Karlsville and extremely evil, but he never actually does any politicking.
- For the Evulz: When Todd asks Karl why he's trying to turn him into a lifeless doll, Karl says that he just needed a hobby.
- I'm a Humanitarian: He orders the townspeople to cook Jessica for him after he turns her into a pig girl.
- Karma Houdini: He escapes the destruction of Karlsville unharmed and can't believe his luck.
- Laughably Evil: His idea of fun is to torment and kill kids with deadly pranks.
- Loves the Sound of Screaming: As Todd screams for help, he tells him "Scream all you want my young boy, it's music to my ears."
- Manipulative Bastard: 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.
- Practically Joker: A monstrous, malicious prankster in a bad purple suit who kills people by playing lethal games with them to amuse himself. Even his name is an implicit reference to The Joker. Many times, The Joker has taken identities related to clowns, jesters and such, including such obscure references as Eric Border. A Knave is an old word for a Fool - or, alternatively...a clown.
- Reality Warper: 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 Looney Tunes character.
- Would Hurt a Child: He only seems to target children, trying to kill one in every episode.
- All of the Other Reindeer: He was ignored by everybody when he was a child, even by his own parents. His reasoning for creating Horrorland is for the sake of making everybody on Earth as miserable as he is.
- Arch-Enemy: Is set up as one to the Morris Family and Clay, on the grounds that they were the only people to ever escape from Horrorland alive.
- The Bad Guy Wins: In both endings of the game. He'll either succeed in turning Mr. and Mrs. Morris into Horrors, or he'll be living with them.
- Canon Foreigner: Is exclusive solely to the video game and hasn't made any other appearances in any other media.
- Large Ham: "WHO STOLE ALL MY CHOCOLATE?!"
- The Man Behind the Man: In the game, he's the man behind Horrorland and the actual creator of the Horrors.
- Troll: He dresses up as his own assistant, Stump, for no reason other than to mess with Lizzy and Luke.
- The Wonka: A psychotic and evil version, but also a subversion. Madison's never going to be fired from Horrorland because he's the boss.
The main protagonist of the first film.
- Batter Up!: Dual-wields twin bats against bees.
- Composite Character: Of several characters from the original series.
- Zackie Beauchamp from The Blob That Ate Everyone.
- Danny Anderson from The Ghost Next Door.
- Kat Merton from It Came From Beneath the Sink.
- Nice Job Breaking It, Hero!: He and Champ are responsible for the film's conflict.
- Sensitive Guy and Manly Man: The Manly Man to Champ's Sensitive Guy.
- Supporting Protagonist: He's the main viewpoint character, but Stine has the main character arc.
The adopted daughter of R.L. Stine, who is secretly one of his creations.
- Canon Character All Along: Halfway through the movie, Hannah is revealed to be the titular protagonist of The Ghost Next Door.
- Dark Is Not Evil: Stine's daughter, Hannah, a ghost girl and one of the heroes (and arguably the most sympathetic protagonist in any of the Goosebumps books) is nonetheless considered a monster due to the fact that she came from a story like the rest of the creatures.
- Dead All Along: Hannah turns out to be this, being the titular protagonist of The Ghost Next Door.
- Face Death with Dignity: Hannah, after Zach realizes he needs to trap her in the manuscript with the other monsters. She gets better, though.
- Interspecies Adoption: Hannah turns out to be this, as she is a fictional ghost raised by the human R.L. Stine.
- Tomato in the Mirror: Subverted, as Hannah knew what she was the entire time, despite what Stine believed.
Zach's friend upon moving to Madison, and the top expert on the Goosebumps series aside from Stine himself.
- Butt-Monkey: Champ, until he saves the girl of his dreams from being mauled by a werewolf. She had been calling him Chump every time she interacted with him.
- Cowardly Lion: Champ, as aside from Stine himself, he is the resident Goosebumps expert and knows how to take out most of the creatures, even if they scare the hell out of him.
- Nice Job Breaking It, Hero!: Champ, along with Zach, accidentally opening one of the manuscripts.
- Only Known by Their Nickname: Subverted from Stine's perspective; Stine assumes that Champ is an example of this trope, but he's not.
- Sensitive Guy and Manly Man: The Sensitive Guy to Zach's Manly Man
The main protagonist of Goosebumps 2: Haunted Halloween.
- BrotherSister Team: Sarah is this with Sonny.
- Crazy-Prepared: Brings along a copy of Frankenstein disguised as R.L. Stine's manuscript, just in case. It turns out to be a smart move, as she manages to fool Slappy long enough to figure out how to use the manuscript to stop the cursed Halloween decorations.
- It's All My Fault: She blames herself for her mother getting kidnapped by Slappy's goons.
- Not What It Looks Like: Downplayed in the opening scene. When her boyfriend enters the apartment with snacks, Sarah's mom Kathy catches the two of them in the act. However, Kathy knows exactly what happened, and is still not happy about it.
- Only Sane Man: The only member of the trio who knows that trusting Slappy is a bad idea.
- Team Mom: Sarah functions as this to Sam and Sonny during Slappy's rampage on Halloween night, especially after her real mother is kidnapped by the monsters.
Sonny Quinn and Sam Carter
The secondary protagonists of Goosebumps 2: Haunted Halloween.
- Black and Nerdy: The only African-American member of the trio, and by far the most awkward.
- Child Prodigy: Sonny managed to create an scale model of the Wardenclyffe Tesla Tower that functioned properly for a while (though Slappy did have a hand in that) and rigged the real thing to short out rather quickly.
- "Eureka!" Moment: Has one when he realizes that he doesn't need to know how to turn off the Wardenclyffe Tesla Tower in order to stop Slappy. He can simply short it out entirely.
- Everyone Has Standards: Sam is horrified at the idea of someone, let alone R.L. Stine, making taxidermy out of a cat.
- Sensitive Guy and Manly Man: Zigzagged. Sonny is the more practical of the two friends, but he has a tendency to give in to bullying. By contrast, Sam is more of a ditz, but always stands up for himself.
- Unwitting Instigator of Doom: The first customer of their business asks them to clean out R.L. Stine's childhood home. This results in the discovery of Haunted Halloween, and the resulting release of Slappy the Dummy.
- Zany Scheme: Sam's plan for creating the Junk Brothers is just one of many of these kinds of schemes.
The author of the Goosebumps books.
- Adults Are Useless: Subverted in the first movie but played straight in the second, where R.L. Stine only arrives after the kids have already defeated Slappy themselves.
- Ask a Stupid Question...: When the protagonists bump into R.L. Stine for the first time, and ask him if he is who they think he is:Stine: No, I'm Dr. Seuss. R.L. Stine was unavailable. Yes, of course, I'm R.L. Stine!
- Berserk Button: Being compared to Stephen King.
- The Cavalry Arrives Late: In Haunted Halloween, he shows up only after the threat has been diminished.
- In Name Only: On a meta-level, this character is, personality-wise, nothing like the real R.L. Stine, save for being the author of the Goosebumps books. This was confirmed both by people who know him personally and by Stine himself, who downright admitted "theres not one true thing in the script". The character was first written with no involvement of the actual Stine, who received the film script when it was basically completed. Nonetheless, he was given some saying on his portrayal and requested to alter some lines.
- I Will Only Slow You Down: Attempts this to Champ, but Champ takes this literally.
- Overprotective Dad: To Hannah.
Slappy the Dummy
The main antagonist of the films and the Night of the Living Dummy series, and the most dangerous of the monsters.
- Adaptational Badass: In the books, Slappy spent his time bullying children into being his slaves. Here, he leads the other monsters in hunting Stine, is clever enough to cut off the whole town, and casually lists off destroying the town as something fun to do.
- Acting for Two: Jack Black plays both R.L. Stine and Slappy the Dummy, which makes sense as Slappy is metaphorically Stine's Evil Twin.
- The Bad Guy Wins: Downplayed. In the second film, the kids succeed in stopping Slappy from destroying the city of Wardenclyffe, but he gets a consolation prize by trapping Stine in a new Goosebumps book he made, finally getting his revenge for being trapped in a manuscript for so long.
- Berserk Button: Being call a dummy, which he finds insulting.
- Dynamic Entry: After being sealed inside a suitcase, Slappy makes his return by skydiving onto Sarah's car.
- Enemy Without: While all the monsters were originally imaginary creations that Stine poured all his negative emotions over his life into before they became real, Slappy stands out the most. He regularly taunts his creator with how much they think alike and Stine refers to confronting him as confronting his personal demons. They're even played by the same actor.
- Joker Immunity: Lampshaded in the second movie by Slappy himself when he shows up in Stine's home.Slappy: You know I always survive. You wrote me that way!
- Knight of Cerebus: In the books, Slappy spent his time bullying children into being his slaves, but doesn't usually stand a chance in a fight and will work with his enemies if he has to. This interpretation of Slappy is more actively malicious, as he releases the other monsters from their manuscripts, is clever enough to cut off the whole town, and hates his creator R.L. Stine with a passion. Stine himself considers Slappy his most dangerous creation, particularly due to how much they are alike.
- New Powers as the Plot Demands: In the second film, Slappy can now make mooks and has telekinesis. Justified in that this Slappy is from an earlier book that was never published, compared to his published books that were edited and made it to print.
- Took a Level in Badass: In the second movie, Slappy now has the power to bring inanimate objects to life, as well as the power of telekinesis and teleportation. Justified, as he's the first version of Slappy that Stine wrote when he was a vengeful teenager working out his frustrations through his writing.
- Villain Teleportation: Slappy is able to go wherever he wants in a flash. He used this ability to steal all of R.L. Stine's manuscripts at once, and in the second film, to escape being locked in a suitcase at the bottom of the lake.
The first monster to escape, specifically from The Abominable Snowman of Pasadena, and the one that kick starts the whole plot.
- Adaptational Villainy: The Abominable Snowman of Pasadena was benevolent in the book. Not so in the movie, though more because it didn't want to go back in the book than because it was evil.
- Continuity Nod: Just one example: the Abominable Snowman of Pasadena's love of trail mix.
- Demoted to Extra: The Abominable Snowman returns in the second movie, but only to serve as a guard for Slappy's lair.
- Disc-One Final Boss: The Abominable Snowman of Pasadena is presented as this. After Stine manages to put him back in the book, he thinks everything is back to normal and gets ready to move out again with Hannah. Then it turns out Slappy got out too.
- Spanner in the Works: Opening this monster's manuscript indirectly led to Slappy's escape, and the dummy decided to release every other monster when Stine tried to imprison him once more, including the Abominable Snowman.
The most numerous of R.L. Stine's monsters, and the main antagonists of Revenge of the Lawn Gnomes.
- Adaptational Badass: The Lawn Gnomes are a lot more dangerous than they were in the books, now throw knives and garden tools at their enemies and their victims.
- Adorable Evil Minions: The Lawn Gnomes are back... and they're throwing sharp things.
- Gulliver Tie-Down: The lawn gnomes quickly tie Stine up this way with electrical cords when he's knocked off his feet.
- Instantly Proven Wrong: At first, Zach thinks the Lawn Gnomes might be friendly. Then they start throwing sharp objects.
- Not-So-Harmless Villain: While the Lawn Gnomes may seem cute, they're also the only monsters who actively try to kill the protagonists. Zach is nearly choked to death before smashing his attackers, and the Gnomes try to roast a tied up Stine in the oven.
- Pulling Themselves Together: The Lawn Gnomes piece themselves together when smashed, effectively making them indestructible.
Giant Praying Mantis
One of Stine's more dangerous creations, and the main antagonist of A Shocker on Shock Street.
- Adaptational Species Change: The giant mantis from A Shocker on Shock Street are described as three times the size of humans. While that alone was dangerous enough, the movie's incarnation portrays the mantis as a kaiju-like threat, big enough to force the heroes' bus into crashing and single-handedly collapsing a Ferris Wheel.
- Adaptational Species Change: While the Giant Praying Mantises in the books where animatronics developed for an amusement park, this mantis is fully organic and the only one of its kind.
- Attack of the 50-Foot Whatever: Large enough to cause immense damage to the town, and destroy entire buildings.
- Big Creepy-Crawlies: The giant praying mantis.
- Fold-Spindle Mutilation: When the giant praying mantis is sucked down into the book, abdomen-first, its parts are compressed one by one. Its enormous head winds up sitting on top of the book, looking a bit confused, just before it disappears.
- Foreshadowing: The fact that Stine initially doesn't remember this monster indicates that he's written so many monsters, even he can't remember all of them. This becomes important at the end when he sees he left the Invisible Boy out of the new manuscript.
The Werewolf of Fever Swamp
The muscle of Slappy the Dummy, along with the Abominable Snowman. Also the main antagonist of The Werewolf of Fever Swamp.
- Car Fu: Used by Zach's aunt to smash the werewolf into a dumpster.
- Demoted to Extra: The Werewolf of Fever Swamp returns in the second movie, but only to serve as a guard for Slappy's lair.
- Heroic Build: While not at all heroic, the Werewolf of Fever Swamp is depicted with an exaggerated dorito build.
- Incongruously Dressed Zombie: The scariness of the Werewolf of Fever Swamp is somewhat diminished by the fact that he wears bright blue lycra jogging shorts and partly ripped-open black athletic shoes with white laces.
- Our Werewolves Are Different: The Werewolf of Fever Swamp is vulnerable to silver like all werewolves, but it can also smell Stine's scent. This bites our heroes in the ass when Slappy uses the werewolf's nose to track them down.
The Invisible Boy
The main antagonist of My Best Friend Is Invisible, he is one of the least dangerous of R.L. Stine's monsters, being little more than a nuisance. At first anyway...
- Acting for Two: Jack Black voices the Invisible Boy, as well as playing Slappy and R.L. Stine himself.
- Adaptational Villainy: The invisible boy wasn't really mischievous in the book. In the movie, he is constantly causing trouble.
- Last of His Kind: Assuming R.L. Stine destroyed the manuscript upon imprisoning all the monsters, the Invisible Boy is the last original monster still on the loose. Hannah doesn't count, as Stine had to recreate her by writing one more book.
- Sequel Hook: The Invisible Boy reveals he escaped being sealed and starts using the magic typewriter to write The Revenge of the Invisible Boy, to Stine's horror.
- The End... Or Is It?: Turns out the Invisible Boy is still outside the books...
- "Who is Veruca Curry? It's a simple question, with a complex answer. But please allow me to try. Veruca Curry is a thoroughly modern witch. A witch on her way up. She's not obsessed with obsolete tradition like her dearly departed grandmother, Sarabeth. Ugh, that choker is so dated. Veruca isn't just out to scare a few kids and steal some babies. No, she's channeling the magical energy from the Whaley House's foundation to amplify a very powerful spell. And, to think, that spell is stored right her on her electronic Grimoire... just a swipe away. A spell that will give Veruca control over the rest of the town! And soon enough, the whole world will see things her way!"
The Big Bad of the three-issue comic book miniseries Horrors of the Witch House, Veruca is the youngest female multimillionaire to come out of Silicon Valley, as well as a Wicked Witch and the granddaughter of Sarabeth, the villain of the original Monster Blood. She has dark designs for the town of Beaver Creek, but faces opposition in the form of three plucky young children named Rosie, Becca, and Carlos.
- Brainy Brunette: She has shoulder-length brown hair and is an accomplished tech designer along with being a powerful witch.
- Dead Guy Junior: Like her late Grandma Sarabeth, Veruca is a witch with ambitions to enslave people and the power to animate objects.
- Even Evil Has Loved Ones: For how at odds Veruca is with her grandmother's ways, she still does miss her, and even keeps a picture of Sarabeth as a cat in her study.
- Eviler Than Thou: She wants to Take Over the World partly due to megalomania, and partly to show up all of the "traditionalist" witches (like her grandmother) who can't be bothered to use their vast magical powers for anything more ambitious than scaring kids and stealing babies.Veruca: I'll show Grandma Sarabeth! I'll show all those old hags who wouldn't update their magic-based applications and evolve their magic strategies! They can't even use smartphones!
- Faux Affably Evil: She is outwardly quite polite and charming, even offering the kids a chance to join in on her plans while relating to their problems with adults. Make no mistake though, she's just as evil as her grandma.
- Femme Fatalons: She has long, sharp pink fingernails.
- Hypno Trinket: She uses a coin to brainwash nearly all of the adults in Beaver Creek.
- I'm Melting!: She dissolves into a puddle of goo after getting drenched in water, in a slightly graphic fashion.
- Kick the Dog: She tries to murder the child protagonists by turning their most cherished possessions into monsters, forcing them to destroy them.
- Kill It with Water: She melts after tripping and falling into a pail of water.
- Magitek: She prides herself on being a "modern witch" whose Grimoire is an iPad-like device.
- Squishy Wizard: Veruca relies almost entirely on her magical tech to cast her spells. When the kids knock her I Pad away, she's about as easy to take down as any ordinary woman.
- Take Over the World: She intends to use the magical energy residing within Haunted Houses to amplify a brainwashing spell, allowing her to take over scores of people all at once, hitting bigger and bigger targets until "the whole world will see things her way!"
- Third-Person Person: During her self-gratifying slideshow.Carlos: Why is she talking about herself like that?
- Weaksauce Weakness: Water.Rosie: Turns out old defenses still work on modern witches.
- We Can Rule Together: She tries to convince the protagonists to join her, but they immediately refuse, so she orders a brainwashed mob (led by their parents) to lynch them.
- "Well Done, Daughter!" Girl: Her whole plan is to outdo her late grandmother and show she can be just as much a menace as the older witches.
- Villainous Friendship: Her online friends include Clarissa from Be Careful What You Wish For..., Belladonna from The Five Masks of Dr. Screem, Aunt Dahlia from "An Old Story" and Mrs. Forster from "Home Sweet Home."
Curly the Skeleton
A character created by Scholastic to be the series mascot. He wasn't an actual character in the series, instead only appearing on merchandise and the covers of the Tales to Give You Goosebumps books. He finally made an appearance in an official product in the comics, as well as being the narrator in Goosebumps: HorrorTown.
- Always Second Best: In Horrortown, he feels this way as a scare-er in regards to his sisters.
- Dem Bones: As the name implies, he is a living skeleton.
- Canine Companion: His pet bulldog, Drool.
- The Dragon: For Slappy in the IDW Comics. The two apparently share some kind of connection, as Curly is shown crumbling into a pile after Slappy gets destroyed at the end of Download and Die!
- Early Installment Character Design Difference: He was a long-haired ghost on the cover of the original Tales to Give You Goosebumps.
- Narrator: He plays this role in Horror Town, often cracking jokes at the expense of the scared citizens. Also, the Collector's Caps books are narrated by him.
- The Voiceless: With the exception of one line at the end of Monsters at Midnight, he does not speak in the comics.
- Pungeon Master: He is one big time in Horror Town, much to Slappy's dismay.
