Characters introduced in the original Goosebumps series, and featured in multiple books:
Evan Ross, Andy, and Trigger
The main characters of the first four Monster Blood books.
- Absentee Actor: Trigger is physically absent from book 4, and it's never said where he's staying while Evan's parents are away. Evan does mention how he was turned into a giant in book 1 though.
- Adaptation Personality Change: Evan and Andy's personalities are toned down in the TV episode.
- Adaptational Jerkass: In Goosebumps Horror Town, Evan and Andy are both obnoxious pranksters, while they were at least intended to be normal kids in the books.
- Aesop Amnesia: Andy never learns that getting involved with Monster Blood will not lead to anything good. Evan learns but is weak willed enough to find himself falling into this in the third book.
- Age Lift: In Horror Town, Evan is a bit younger than 12, while Andy is closer to a teen.
- All of the Other Reindeer: Evan gets off to a bad start by telling everyone about his Monster Blood misadventure upon starting at his new school, resulting in all the kids thinking he's weird.
- Asleep in Class: Evan falls asleep in class at the start of the second book and is woken by his teacher.
- Belligerent Sexual Tension: Evan and Andy seem to have a preteen version of this.
- Berserk Button: Don't call Andy by her real name, Andrea. And especially don't stretch it out.
- Big Damn Heroes: Evan in the second book, when he eats Monster Blood and grows enough to be able to burst into the classroom, save Conan from Cuddles and fight off the giant hamster. He almost gets his head bitten off but the magic in the Monster Blood runs out right on time.
- Big Friendly Dog: Trigger the cocker spaniel, who's friendly to pretty much everyone.
- Bully Hunter: Andy has shades of this in the first book. She despises the Beymer twins for their bullying and stands up for Evan when they pick on him. She also stands up for him to Conan.
- Butt-Monkey: Evan. Nothing ever works out for him, his parents are always leaving him with other relatives he doesn't like and who don't like him either, he's picked on and beaten up, and he finds himself stuck in situations involving a horrible living blob creature.
- The Cameo: Evan has one in Return to Horrorland, where he appears on TV and shows off the Monster Blood, causing the kids to mock him.
- Cassandra Truth: When Evan tells Andy that no one believed his Monster Blood stories, her response is along the lines of "no shit, Sherlock".
- The Chew Toy: 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, or just plain treated like crap by his parents, aunt or teacher.
- Deadpan Snarker: Andy.Evan: It's so dark.Andy: It usually gets dark at night.
- Do Not Call Me "Paul": Andy hates to be called by her full first name, Andrea.
- Iron Butt-Monkey: Seriously, from all the beatings Evan received from Conan, it's a wonder how none of them put him in the hospital.
- Irrational Hatred: Evan despises Cuddles the hamster for some unclear reason, to the point of fantasizing about throwing him out a window or crushing him into a pancake. The feeling is likely mutual when the rodent becomes a giant.
- Jerk with a Heart of Gold: While Andy teases Evan constantly and does some other questionable things, it's pretty obvious she does care about him. Her reason for bringing more Monster Blood in the third book is even so he can fight off Conan.
- Kiddie Kid: The first MB book starts off with 12-year-old Evan throwing a tantrum like a child half his age. His mother even lampshades this at some point, scolding him for acting like an infant.
- Masculine Girl, Feminine Boy: Evan isn't necessarily "feminine" but he's very weak-willed and pessimistic compared to Andy, who is a lot more brash, daring, and idealistic. Andy even protects him from bullies.
- Never My Fault: Evan desires payback against Mr. Murphy for making him clean Cuddles' cage, even though he mouthed off to his teacher for not believing a story about evil goop and cat witches.
- Nightmare Sequence: Evan has one at the start of both the second and third book.
- Only Friend: Andy is definitely this to Evan, and Evan seems to be this for Andy as well.
- Only Sane Man: Evan plays this role in the last two books, with Andy's eagerness to use the Monster Blood and Kermit's brattiness and crazy inventions.
- Parental Neglect: Both Evan and Andy's parents constantly abandon them with relatives, with Evan's parents doing so in every book except the second and Andy's parents making her stay with her aunt and uncle in Atlanta near Evan's place.
- Pet the Dog: There's a scene in the first book where Andy finds some bullies tied a cat to a tree and helps untie it.
- Plucky Girl: Andy, who's a lot more idealistic than Evan and refuses to back down over anything.
- Poisonous Friend: Andy, to Evan. While her heart is in the right place she almost always ends up making things worse for him. In the second book, when no one believes him about his Monster Blood story, she tries to prove it by feeding the hamster Cuddles Monster Blood to see if he grows. He does indeed grow, which proves it, but now they have the obvious problem of a giant monster hamster on the loose (fortunately, said hamster goes back to normal at the end. Also, in book 3, she suggest that Evan himself eat Monster Blood so he can get big enough to beat up Conan. He does eat and it does grow, unfortunately, he keeps growing till he's 20 feet tall or so. Fortunately, he also returns to normal at the end.
- Puppy Love: Andy and Evan are the closest thing in the series to an Official Couple, though it's likely neither of them would admit it.
- The Quincy Punk: Andy's redesigned appearance in Goosebumps: HorrorTown, which is also a major case of Younger Than They Look.
- Redheads Are Uncool: Evan has red hair and is a colossal loser.
- Savvy Guy, Energetic Girl: Andy is much more daring, bold and impulsive than Evan, who is more cautious about using the Monster Blood and breaking into Conan's house.
- She's a Man in Japan: Evan and Andy's genders are switched in the Dutch version of the books.
- Skewed Priorities: When Trigger eats the Monster Blood in the first book, Andy worries that there isn't enough to share.
- Straw Loser: 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.
- They Do: Averted. Even though there certainly seems to be something between them, they never so much as hold hands.
- Throw the Dog a Bone: When Evan gets turned into a giant in the third book, he actually has a rather good time after his initial despair, saving kids from getting picked on by Conan, retrieving kites stuck in trees and even getting revenge on Conan by hanging him to a tree the same way he did to Andy and crushing his skateboard.
- Too Dumb to Live: Andy always tries to goad Evan into using Monster Blood to avenge himself on his tormentors, such as Conan, Kermit, and one of his teachers, even though she has firsthand knowledge that these attempts will not work and just make things worse. One time (in the second book) she even goes behind Evan's back and uses the Monster Blood after promising him not to do so. Evan falls into this category in the third book when he decides to go along with Andy's plan to get payback on Kermit, which of course fails.
- Took a Level in Badass: After being a loser for most of the second book, Evan eats the Monster Blood to save the school, becoming a hero and redeeming himself to his teacher and most of his classmates.
- Took a Level in Jerkass: Andy was a much better friend to Evan in the first book. Despite teasing him a lot, she stood up for him against the Beymer twins and angrily said they'd get back at them when they beat Evan up. In the sequels, she frequently brings back the Monster Blood and suggests Evan use it, even though it nearly killed her and Evan in the previous books, and even feeds the Monster Blood to Cuddles the hamster in the second book after promising Evan not to.
- Vitriolic Best Buds: Evan and Andy regularly banter and tease each other.
- With Friends Like These...: Despite being Evan's best friend, Andy keeps bringing back the Monster Blood and insisting Evan use it while knowing the trouble it caused both of them, and even goes behind Evan's back and feeds it to Cuddles in the second book after assuring him he wouldn't.
A mass of growing goo and monster of the Monster Blood series.
- Attack of the 50-Foot Whatever: What results from its consumption.
- Blob Monster: One that resembles Gack.
- Extreme Omnivore: It will devour everything that comes in contact with it, and doesn't discriminate between kids, animals, or even its master Sarabeth.
- Generic Doomsday Villain: This is to be expected, since it's a mindless life form, but its 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.
- Hungry Menace: It exists only to devour.
- Mutagenic Goo: 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 Body Horror as his muscles swell and he becomes an inhuman lump.
- Retcon: In the original novel it's stated that Monster Blood really is a mundane novelty toy, and that Sarabeth only cursed the particular can found by Evan and Andy. Since unrelated Monster Blood cans keep turning up in the sequels with identical powers, it's unclear whether Sarabeth's spell somehow affected all cans of Monster Blood everywhere or if this is just an unaddressed Series Continuity Error.
- Sealed Evil in a Can: And some sap always winds up opening it...
- Series Mascot: It forms the title of the series.
An incredibly nasty and vicious cat owned by Evan Ross's aunt Kathryn. When Evan has to stay with Kathryn for a few weeks, Sarabeth frequently attacks him. She's actually an evil witch, and she's kept Kathryn has her slave for twenty years. When she couldn't get rid of Evan herself, she made Kathryn enchant the Monster Blood so it would kill him, but she gets killed by her own creation.
- Adaptation Personality Change: The TV show tries to give her more motivation and an actual background beyond being Kathryn's False Friend. Kathryn explains Sarabeth was originally renting a room from her when she walked in on Sarabeth performing some spell with the Monster Blood. In the process of being discovered, Sarabeth panicked and was about to attack Kathryn when she stepped into the Monster Blood and it... did something to her. The implication is the Monster Blood somehow drained Sarabeth of her magic and she turned into a cat, while Kathryn bottled it up and hid it somewhere. By freeing the Monster Blood, her powers got restored and she was able to turn human again.
- Baleful Polymorph: The TV show implies she stayed as a cat for so long because she couldn't change back to human.
- Cats Are Mean: Kathryn herself tells Evan that Sarabeth is an evil cat.
- Evil Is Petty: She made Kathryn deaf by magic, and has specifically kept her from learning sign language in order to keep her weak. She's also more than happy to let her Monster Blood kill everyone as long as her secrets remain safe.
- Evil Redhead: Her human form. Though in the TV show her hair's a shade of dark brown.
- False Friend: Kathryn claims that when they first met, she thought Sarabeth was her friend. That was before Sarabeth revealed she was Evil All Along.
- Flat Character: While most antagonists have some backstory or flimsy motivation to justify why they do what they do, Sarabeth has no character beyond being evil and wanting to enslave Aunt Kathryn. She's only in the first book as a last minute villain, and is never seen or mentioned again outside of the comic book story Horrors of the Witch House, the villain of which turns out to be Sarabeth's granddaughter, who invokes Eviler Than Thou on the "dearly departed" Sarabeth.
- Greater-Scope Villain: Of the Monster Blood books in the sense that it's due to her magic that the toy goo came to life. Though this only extends to the actual Monster Blood and not the fake blue variant from the last book.
- The Man Behind the Man: She's the one who brought the first Monster Blood can to life, but it's left ambiguous if her magic enchanted every Monster Blood can or if Monster Blood was already magic.
- Villain Ball: Her death is entirely her own fault. She was afraid Evan would find out her secret and wanted him dead, but if she just left him alone she wouldn't have died.
- Wicked Witch: A shapeshifter.
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. 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.
- Blob Monster: Ones shaped like weird blue slugs with razor teeth.
- I Am Not Weasel: 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.
- Mix-and-Match Critters: They're like a cross between slugs, leeches, and bottom feeders made out of blue slime.
- More Teeth than the Osmond Family: 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.
- Self-Disposing Villain: 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.
- Took a Level in Jerkass: The creatures are fairly tame and benevolent at first, but they more they multiply the angrier they get. 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.
The resident bully and secondary antagonist for most of the Monster Blood series.
- Adaptational Heroism: In the TV episode More Monster Blood, he helps save the day and becomes much nicer at the end.
- Big Man on Campus: Evan remarks that he looks 32, even though he's only 12.
- The Bully: He loves tormenting Evan and getting him in trouble with their teacher.
- Bullying the Dragon: Literal example on the "bullying" part. Even after he sees Evan as 12 feet tall, he still mocks him on his height. This ended as well as you would expect.
- Crushing Handshake: He gives three of these to Evan in Monster Blood II, and each is more painful than the last.
- Dirty Coward: He's not so tough and badass when it comes to heights and giant hamsters.
- Disproportionate Retribution: On his first encounter with Evan, he once told Evan, "We don't like wise guys here in Atlanta" and beat him up afterwards, right after Evan told him about Monster Blood.
- Hate Sink: He's a stereotypical bully who takes every opportunity to make Evan miserable and never gives him a break, even after he saves his life.
- Hidden Depths: Word of God says that he sleeps with a teddy bear named Fluffster (who makes an unnamed cameo in Monster Blood II) and gets a bedtime story every night.
- In-Series Nickname: "Conan the Barbarian", unsurprisingly.
- Jerkass: He'll beat up on Evan even if he never even did anything to him.
- Jerkass Has a Point: He was right that Evan telling everyone about the Monster Blood was something that no one would legitimately believe, though that doesn't justify his bullying.
- Jerk Jock: He actually slam dunks Evan through a basketball hoop in one part of Monster Blood II.
- Manipulative Bastard: He's very good at convincing Mr. Murphy that he's entirely innocent and Evan was the one picking on him.
- Misplaced Retribution: Every time Kermit's experiments backfire on Conan or he does something else unpleasant to him, Conan takes it all out on Evan. In the fourth MB book, after Kermit sprayed Conan's new sneakers with water from a Super Soaker, Conan took his anger out on Evan as the latter protests he didn't do anything to him. Conan's response? "It came out of YOUR squirt gun!"
- No-Holds-Barred Beatdown: He constantly gives these to Evan thanks to the trope mentioned above.
- Shout-Out: If his name is too subtle for you, he's even nicknamed Conan the Barbarian.
- A Taste of Their Own Medicine: He hangs Andy to a tree after beating up Evan, and gets hung to that same tree by Evan when the latter turns into a giant.
- Took a Level in Kindness: In the TV adaptation, anyway. He not only helps defeat the Monster Blood, but becomes friends with Kurtis, one of the kids he used to bully.
- Ungrateful Bastard: Even after Evan saves him from getting eaten by Cuddles, he still bullies him at every opportunity.
- Why Did It Have to Be Snakes?: He's afraid of heights.
- Wouldn't Hit a Girl: Since he doesn't hit girls, he sticks Andy on a high tree branch instead after he beats up Evan.
- Wounded Gazelle Gambit: Somehow, he's able to convince Mr. Murphy that a wimp like Evan can hurt a much bigger and more muscular bully like Conan.
- Younger Than They Look: As stated above, he looks far more muscular and broad than the average 12-year-old, making him look more like an adult than a preteen.
Cuddles the Hamster
Mr. Murphy's pet hamster, who grows to enormous size and goes on a destructive rampage after eating Monster Blood.
- Attack of the 50-Foot Whatever: The climax of the book.
- Breakout Character: Despite only appearing in one book, Cuddles became one of the most prominent of the monster characters featured in the 1990s merchandise. However, he was Demoted to Extra when the franchise was revitalized with the Horrorland series, to the point that Monster Blood II has yet to be reprinted.
- Child Eater: It's implied that he was going to eat Conan before Evan stepped in.
- Fat Bastard: According to Evan - and that's before he grows to the size of a gorilla.
- Here We Go Again!: Monster Blood II ends with him eating Monster Blood brought by Andy yet again.
- Rodents of Unusual Size: After he eats Monster Blood.
- 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.
Evan Ross's bratty cousin, a self-described child genius and inventor who uses Evan to test his experiments on when he's not deliberately getting Evan in trouble. First appears in Monster Blood III.
- Bratty Half-Pint: To an extreme degree.
- Child Prodigy: More of an Informed Attribute since his inventions rarely work, though the fact that he can create any at all despite being only eight is rather impressive.
- Consummate Liar: His mother believes everything he says whenever he talks about Evan provoking people.
- Creepy Child: The way he delights in torturing Evan and manipulating his mother makes him come off as this.
- Hate Sink: Has no personality traits beyond being a lying, obnoxious brat and only exists to make Evan's life even worse. What makes him even less likable is that he usurps the supporting protagonist role from fan favorite Andy in the Monster Blood books.
- Insufferable Genius: Creates weird concoctions and experiments with Monster Blood. Both often end in failure.
- Jerkass: His only purpose in the story is to make Evan suffer and get him in trouble with no remorse or hesitation.
- Karma Houdini: Almost never gets punished for his experiments backfiring or getting Evan in trouble.
- Kick the Dog: Not only does he get Evan in trouble on purpose multiple times, he offers to do Andy's math homework and gets all the problems wrong intentionally, seemingly just to be a dick.
- Lack of Empathy: He actually laughs when Conan starts beating up Evan.
- Mad Scientist: A kid one. He even self-identifies as one in Monster Blood IV.
- Manipulative Bastard: He'll goad Conan Barber into beating Evan up by antagonizing Conan and hiding behind Evan. He'll tell his mother Evan was picking fights to get out of any blame.
- Pet the Dog: Helping Evan shrink back to his normal size in the third book. He also attempts to help Evan get back at Conan in the fourth book.
- The Sociopath: He takes delight in making Evan miserable and tormenting him and shows no remorse for the horrible things he does or for lying to his mother.
- Spoiled Brat: His mother practically lets him do whatever he wants while always blaming Evan and Andy for his actions.
- White Hair, Black Heart: He has white-blond hair and is a total jerk.
- Wounded Gazelle Gambit: He pulls this off on Evan and Andy in the third book when he blames them for the horrible mess around the yard to his mother, who automatically believes him.
Mr. MurphyEvan's science teacher.
- Deadpan Snarker: "Maybe a science fiction teacher would believe it. Not a science teacher." Afterwards, he sarcastically asks Evan if the teachers at his old school liked it when he called them dumb.
- Fat Bastard: Much like Cuddles. He's a Sadist Teacher and obese to boot.
- Jerkass Has a Point: He was right that Evan shouldn't have fallen asleep in class, told everyone about Monster Blood or called him dumb.
- Sadist Teacher: Apart from making fun of Evan for falling asleep in class, he does nothing to stop Conan's bullying of him, even when he does things like throw a basketball at Evan's face and slam dunk him through the hoop.
- So Proud of You: He says this to Evan when the latter saves the school from Cuddles.
Rick and Tony BeymerTwin bullies in the first book.
- Asshole Victim: They get eaten by the Monster Blood when it's in its Blob Monster form. Fortunately, they come out alive when it's defeated.
- The Bully: Even worse than usual for these books. They even give Evan a surprisingly graphic No Holds Barred Beat Down.
- Jerkass: They bully younger kids and tie defenseless animals to trees.
- Kick the Dog: They tie a cat to a tree, apparently just for fun. Thankfully, Andy frees it.
- Laser-Guided Karma: When the Monster Blood encompasses them.
- Teens Are Monsters: They're 14-year-old delinquents who beat up younger children and even torture animals.
- White Hair, Black Heart: They are described as having very light, almost white/blond hair.
Matt's obnoxious next door neighbor in Monster Blood for Breakfast.
- Asshole Victim: At the end of the book, when the ivy plants Matt owned that Bradley stole and falsely stated he caused to grow in order to win the science fair start snaking their tendrils around him.
- Big Eater: Matt says it's hard to believe he's so skinny with how much he eats.
- Catchphrase: "No biggie", much to Matt's irritation.
- Hate Sink: His whole personality revolves around how annoying and obnoxious he is.
- Hero-Worshipper: Despite how badly he treats Matt, he's also said to worship and admire him, "borrowing" his T-shirts and ideas for science projects.
- In-Series Nickname: The start of his last name, "Worm".
- Jerkass: He's almost as bad as Conan and Kermit.
- Laser-Guided Karma: At the end of the book, the ivy plants he stole from Matt and presented as his science project start wrapping their tendrils around him. Matt notices this and congratulates him for winning the science fair instead of warning him. Considering everything else he did to him as well as stealing his science project, this is understandable.
- Lean and Mean: Matt notices how skinny he is, and while not evil, he has few redeeming qualities.
- Pet the Dog: When Matt is about to be suspended for attacking him, Bradley stands up for him, saying they were just goofing around.
- With Friends Like These...: Claims to be Matt's "friend", but acts like anything but, constantly getting him in trouble for things Bradley did and showing little remorse for doing so.
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.
- Adaptational Nice Guy: In the TV series, Greg is much more likable. For example, while in the book he tried to take a picture of Mr. Saur (not that he didn't deserve it), in the TV series, he outright refuses to take a picture with the camera when Mr. Saur wants proof It's still very satisfying when Mr. Saur accidentally takes a picture of himself and goes bald.
- Aesop Amnesia: He seems to forget all the horrible things the camera caused in the first book and decides to retrieve it to show to Mr. Saur just to get a good grade in English.
- Body Horror: Besides the camera making him obese, it also causes him to develop a horrible skin rash that makes him look like a lizard.
- Butt-Monkey: More so in Say Cheese And Die - Again! due to Mr. Saur and his classmates' treatment of him and what the camera does to him.
- Cassandra Truth: 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 on visiting his cousins for the summer, he thought finding the camera was the only way to have his grade fixed.
- Didn't Think This Through: Seriously, Greg! What were you thinking writing a book report about your misadventures of the evil camera for your class assignment?!! Especially a class taught by Sourball Saur?!!!
- Lethally Stupid: Upon discovering the camera is potentially dangerous to anything in takes a picture of, you'd think Greg would test it by taking a picture of some expendable object he doesn't care about in case it gets destroyed by the camera. Instead he takes a picture of his brother Terry. No, Terry isn't a Big Brother Bully, nor does Greg even dislike him. He's just that dumb.
- Only Sane Man: Greg is considered the sensible one in his group of friends, and he doesn't like it because they tease him for it.
- Revenge Before Reason: 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. And then the book ends with Mr. Saur taking a picture of the whole class, but it's left ambiguous as to what happened.
- Throw the Dog a Bone: 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 Laser-Guided Karma for his treatment of Greg.
- Too Dumb to Live: If writing a report about his encounter with the camera for English class wasn't dumb enough, he even decides to retrieve it just to prove its existence to his teacher and attempts to bring it to class even after all the trouble I think caused to snap a picture of Mr. Saur to get revenge on him for his cruelty. Predictably, this doesn't end well.
- Took a Level in Dumbass: 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. In the first book, he had to be pressured by his friends to continue using the camera while being reluctant to do so, while in the sequel his friends pressure him not to use the camera when he knows full well how dangerous it is.
- Weight Woe: 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. Mr. Saur, on the other hand, does nothing but mock him.
- What Happened to the Mouse?: 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. The implications behind this are not helped by the Ambiguous Ending to Say Cheese And Die - Again!
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.
- Bad Future: Its specialty.
- Body Horror: Some of the worst in the series. Besides the Weight Woe 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.
- Fate Worse than Death: 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.
- Happy Fun Ball: It simply looks like an ordinary camera, but it's pure evil. At least in the book. In the TV episodes, it looks more like Darth Vader's toaster than a camera.
- It Can Think: 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!
- Spooky Photographs: The camera will cause bad things to happen to those who are photographed by it, ranging from simple accidents to car crashes.
- Took a Level in Jerkass: 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 Bad Future photos. Body Horror and mutilation are a big factor in this.
Fritz "Spidey" Fredericks
A creepy hermit who lives in the Coffman house and the partner of the inventor of the Evil Camera.
- And I Must Scream: In the TV episode, he is imprisoned in the camera when he gets his picture taken... until the two bullies unwittingly release him.
- Anti-Villain: He's not really evil, since he created the camera by accident, but he does try to imprison Greg and Shari when they return the camera.
- Composite Character: In Goosebumps: HorrorTown, he takes the place of Dr. Deep from Deep Trouble. There's even a Mythology Gag where he claims that his Dr. Deep was one of his nicknames.
- Greater-Scope Villain: He stole the camera from his partner, causing the latter to put a curse on it to cause bad things to happen, while originally it just predicted the future.
- He Knows Too Much: His reason for refusing to let Greg and Shari leave after telling them the backstory of the camera.
- Hoist by His Own Petard: In the book, he dies of a heart attack caused by the camera. In the TV episode, he is merely imprisoned in it.
- Misunderstood Loner with a Heart of Gold: Played with - he's an antisocial outcast whom most of the locals are creeped out by, but he's just paranoid and mentally ill. On the other hand, he's not exactly a saint, either.
- Tragic Villain: He had his life ruined by the camera, losing his job and family.
- Unwitting Instigator of Doom: He co-designed the camera with another scientist, who placed a Bad Future curse on it after Spidey took all the credit for the invention.
Greg Banks' complete asshole of a teacher in Say Cheese And Die - Again! He gives Greg an "F" on his report about the Evil Camera, which is understandable, but doesn't justify his cruel and malicious treatment of Greg afterwards.
- Adaptational Karma: In the TV show, which tones down Greg's less appealing personality traits, Saur has his picture taken by the camera and loses his hair. Specifically, it immediately begins falling out while the students laugh at him as he screams "IT'S NOT FUNNY!"
- Embarrassing Nickname: "Sourball."
- Hate Sink: His attitude towards Greg and belittling nature after Greg is cursed with obesity is utterly cringe worthy enough to wish Greg would take his picture.
- Jerkass: He's much worse to Greg when he starts mocking his weight.
- Jerkass Has a Point: Greg should've known better than to write a report about the Evil Camera and automatically expect his teacher to believe it, but that still doesn't excuse Saur's abusive attitude.
- Meaningful Name: As sour as his last name sounds.
- Sadist Teacher: When Greg comes to class morbidly obese, Saur is the only person in the room who continues to mock Greg for his weight, when even the class bullies realize something is really wrong with the kid. When your students are more mature than you, that's saying something.
The newest owner of the Evil Camera in Say Cheese and Die - Screaming! She bought at a garage sale, but quickly tried to get rid of it after realizing how dangerous it is. Unfortunately, the camera keeps finding its way into Julie's life.
- The Atoner: Does everything she can to try and circumvent the camera's power out of guilt for harming Reena and Karla.
- Camera Fiend: She was interested in photography even before finding the evil camera.
- Convicted by Public Opinion: Even after dumping the camera, people associate it with her because they saw it in her possession first. After Becka and Greta are given horrible rashes by the camera, they blame Julie, threatening to sue her family and calling her a witch.
- Gaslighting: The Evil Camera resurfacing in her home was actually David trying to mess with her head so he could win the photography contest.
- Karmic Jackpot: Her earlier realization of how dangerous the camera is mixed with her determination to get rid of the thing and to break its power as well as her trying to save David Blank from falling to his death manages to undo the magic of the camera and gets her labelled a hero by the kids and teachers in her school.
- Kid Hero: Her rival David almost falls to his death while taking their class yearbook photo, and Julie rushes to rescue him. In the process, she almost falls herself and fulfills the camera's prediction, but David saves her as well. This not only creates a possible new friendship between them, but restores Julie's good name to her classmates after thinking she maimed Reena and the others.
- My God, What Have I Done?: Is immediately wracked with guilt when the camera blinded Reena and injured Karla, especially when Reena cuts all ties with her. This is because, as Reena points out, the woman who originally owned the camera didn't want Julie to have it, but the woman's daughter gave it to her. Reena saying Julie acts like she knows everything makes Julie feel incredibly guilty.
- Redeeming Replacement: To Greg Banks as the protagonist of the Say Cheese and Die! books.
- Sitcom Arch-Nemesis: With David Blank. Both are talented photographers and are constantly trying to show the other up. Julie lets David take the class photo for the yearbook even though she rightfully won the opportunity. David, who had previously been a giant asshole to Julie, sincerely asks if she's really okay with this. This is because the Evil Camera photographed Julie falling to her death while taking the yearbook photo, and Julie believes it's safer for David to do it. Unfortunately, the camera's smarter than that.
- Women Are Wiser: She immediately comes across as saner than Greg Banks when she doesn't take as long to get the camera out of her life. Though it helps that, unlike Greg, Julie gets called out on using the camera when she loses her best friend.
Gabe Sabry and Sari Hassad
Two Egyptian-American cousins who repeatedly find themselves getting lost in pyramids and mixed up with ancient curses and mummies being brought back to life.
- The Ace: Sari, big time. She's a straight-A student, is always finding ways to one-up Gabe, and is so competitive that she can literally turn eating breakfast into a contest.
- Butt-Monkey: Gabe constantly finds himself being the butt of his uncle and cousin's practical jokes.
- Chekhov's Gun: The Summoner, a mummy hand that Gabe keeps as a good luck charm. It seems like a cheap trinket, but ends up being a major plot device in both books.
- Clashing Cousins: Sari likes pranking Gabe and Gabe is frustrated by that and by how competitive she is.
- Competition Freak: Sari. Gabe says she can even turn breakfast eating into a competition.
- Daddy's Girl: Sari. Justified because her mom died when she was young and she only sees her dad during the holidays.
- Hidden Depths: Sari talks a big game, but is actually rather squeamish when it comes to the gory details of mummification. The second book also has a kind of sweet part where she confides to Gabe the reason she is being so annoying is she's worried the whole excavation will turn out to be a bust and Uncle Ben's reputation could be ruined.
- Insufferable Genius: Sari loves flaunting her intelligence to Gabe as well as her pranking him.
- Lovable Alpha Bitch: Despite being a Proud Beauty AND an Insufferable Genius she has some more endearing qualities, such as her bravery, and helps the three of them get out of danger multiple times.
- Missing Mom: Sari's mother died when she was little.
- Named by the Adaptation: Gabe's surname comes from the TV version of Return of the Mummy.
- The Prankster: Sari likes to prank Gabe whenever he visits her.
Uncle Ben Hassad
Gabe's uncle, an Egyptian archaeologist who spends his days exploring pyramids. He does serious work, but that doesn't stop him from being a world-class practical joker.
- Beware the Silly Ones: He may have a major knack for jokes, but he knows when to be serious. Particularly when his daughter and nephew get lost in a pyramid.
- Cool Uncle: To Gabe, who doesn't hesitate to stay with him when his parents offer - of course, that changes when he hears that Sari is also with him.
- Horrible Judge of Character: Even after being told that Ahmed wants to kill and mummify Gabe and Sari, he still thinks he can rationally talk things over "as scientist to scientist". Needless to say, the Brotherhood of Man approach doesn't work too well. In the sequel, he's the same way with Nila, partly because he has a crush on her.
- The Prankster: A trait he shares with his daughter.
- Reasonable Authority Figure: Like Dr. Deep, he does his best to protect the children, even if he's useless against the villains.
A superstitious scientist who takes ancient curses a little too seriously.
- Ax-Crazy: Anyone who violates the tomb is either mummified alive, or thrown into a flaming tar pit. Not to mention, he seems to REALLY love this job.
- Big Bad: Of The Curse Of The Mummy's Tomb.
- Even Evil Has Standards: His methods are unforgivably horrific, but Ahmed does try to warn explorers away when he can, and only resorts to murder if they breach the tomb.
- Humans Are the Real Monsters: The mummies are actually the victims and Ahmed is the one murdering anyone who invades the tomb.
- Karma Houdini: Other than being scared off by the mummies at the end he basically gets off scot-free. Even more weirdly, he is never heard from or even brought up again, even in the sequel. You would think one of the characters would say "hey, remember that guy Ahmed who tried to murder us last year"? Or something like that, but no.
- Knight of Cerebus: He's right up there with Mr. Toggle and the Lord High Executioner as one of the darkest villains in the series.
- Knight Templar: Claims to turn temple intruders into mummies to appease his ancestor's curse. It's not clear if the curse is actually real, but considering this is the Goosebumps universe...
- Screw This, I'm Outta Here!: 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.
- Soft-Spoken Sadist: He speaks very calmly and quietly, even when informing Gabe and Sari of their imminent deaths.
- They Look Just Like Everyone Else!: He seems pretty normal and nondescript when we first meet him. It becomes clear soon enough that his intentions aren't good, but there's no clue to just how deranged he is until the end.
- Would Hurt a Child: Even if you're a kid and stumble into the tomb by accident. He even shrugs this off by telling Gabe that plenty of pharaohs died at his age.
A reporter from the Egyptian newspaper, "The Cairo Sun", Nila befriends Gabe and his family in "Return of The Mummy." In reality, she's actually a thousands year old Egyptian princess who hopes to use the Hassad family as a means to resurrect her brother. A character resembling her appears in a promotional shot for the Goosebumps movie. She's not particularly strong, but the lengths and steps she takes to find her brother are impressive.
- Ambition Is Evil: Wants to resurrect her brother, Khor-ru, so they can make a comeback and take over Egypt together.
- Animorphism: Can transform into a scarab, which is somehow connected to her amber pendant.
- Big Bad: Of Return Of The Mummy.
- Bitch in Sheep's Clothing: To Gabe and Sari's horror.
- Cain and Abel: Her brother tries to strangle her after waking up. Admittedly, it's less out of hatred and jealousy and more because he didn't want to be reanimated by anyone.
- Femme Fatale: She uses Uncle Ben's crush on her to gain his trust before knocking him out and stuffing him in a sarcophagus.
- Even Evil Has Loved Ones: She may be a sociopath, but Nila was willing to go to extremes to bring her brother back so they could rule together. She also mentions her mother as the one who named her.
- Incest Subtext: She's driven to resurrect her brother above anything else in order that they can "rule together". It's not elaborated upon since it's a children's book, but considering that Egyptian royalty practiced dynastic incest... and to make matters worse, Prince Khor-ru is a desiccated corpse by that point.
- Really 700 Years Old: Pretty awkward, considering Gabe's uncle had a crush on her...
- Shapeshifter Mode Lock: Her ultimate fate, after Gabe smashes her pendant.
- Shoot the Shaggy Dog: Waits for thousands of years to begin her plan, creates a new identity, manipulates an archaeological dig, harnesses Gabe's power, brings back Khor-ru... only for her brother to want nothing to do with her, and then gets trapped in scarab form thanks to Gabe's interference. Though it seems thanks to the movie, she'll get another chance.
- Soul Jar: Her scarab pendant. It's apparently what allows her to maintain human form.
See Night of the Living Dummy Saga page.
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. She has a lesser role in The Haunted Mask II, but returns to prominence in the Goosebumps Horrorland book The Scream of the Haunted Mask.
- All of the Other Reindeer: Her tendency to be easily scared makes her an easy target for pranks, even by her friends. She even thinks at one point that she's become the laughingstock of her school.
- Be Careful What You Wish For: She almost lost her humanity for the sake of getting her revenge.
- Butt-Monkey: She grows out of it.
- The Bus Came Back: She's the only protagonist confirmed to appear in the upcoming movie. Unfortunately, it's as the mask's host.
- Demonic Possession: The mask not only becomes her face, but compels her to do horrible things.
- The Dog Bites Back: Tired of being pranked and tormented for being a scaredy-cat, she decides she's going to scare people instead.

- Evil Is Not a Toy: 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.
- The Friend Nobody Likes: Chuck and Steve enjoy scaring and embarrassing her and even her best friend Sabrina occasionally makes fun of her.
- Grew a Spine: She's a lot less scared in the sequel and even managed to scare Chuck and Steve a second time.
- He Who Fights Monsters: She just barely avoided becoming a literal monster forever when she got back at Steve and Chuck.
- Only Sane Woman: In the Horrorland series, she soon becomes the most levelheaded member of the group.
- Shrinking Violet: 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.
- Threshold Guardian: In Scream Of The Haunted Mask, she hides the mask in her basement to keep it from menacing anyone else.
- Took a Level in Badass: Grows much more brave and tough from the Halloween she spent with the mask.
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.
- A Day in the Limelight: As a result of The Haunted Mask II.
- Ascended Extra: 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.
- The Bully: Similar to Conan Barber in the Monster Blood books, he's a bully in every Haunted Mask book he's appeared in, though significantly less harmful of one since his bullying is limited to mean pranks while Conan's crosses into physical abuse. However, he's also a bully whose victim has begun asserting herself and he becomes rather pathetic as a result.
- Butt-Monkey: 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.
- Break the Haughty: 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.
- Child Hater: 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.
- Heroic Sacrifice: In the TV show, he throws himself in front of the haunted mask when it targets Carly Beth to protect her. This turns out to be the symbol of love that frees his own mask from his head.
- Jerkass: He savors every moment of scaring Carly-Beth and pulling cruel pranks on her in the first book. Even in the sequel, he still has shades of this after setting loose a squirrel in the girls' locker room.
- Jerk with a Heart of Gold: In the TV show. He delights in scaring and pranking Carly Beth, but also reveals he just does it because he likes her, and in The Haunted Mask II, puts himself in front of the haunted mask even while he's suffering in his own mask to protect her.
- Laser-Guided Karma: Is scared shitless by Carly-Beth in the first book and then treated like crap by the first graders in the second book.
- Loving Bully: In the TV show, he claims the reason why he picks on her so much is because he actually likes her. This turns out to be true when he saves her from having the evil mask from the last movie bond with her again.
- The Prankster: His pranks are primarily directed at Carly Beth.
- Promoted to Love Interest: For Carly Beth in the television series, where he admits he always teased her because he liked her and makes a Heroic Sacrifice to save her, which is called another "symbol of love" in-universe.
- A Taste of Their Own Medicine: In The Haunted Mask II, he's tormented by the first graders the same way he tormented Carly Beth.
- Took a Level in Kindness: 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.
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 All There in the Manual 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.
- Adaptation Expansion: In the TV episode of The Haunted Mask II he has a greatly expanded role, wherein he gets taken over by the original Haunted Mask.
- All There in the Manual: His backstory is provided in the Goosebumps Collector's Caps Book, wherein it's revealed he was injured and turned into an adult in a high school chemistry accident, leading him to begin creating the masks.
- Dark Is Not Evil: Despite his all-black attire and generally slightly threatening manner, he isn't that bad of a guy, just sort of moody and depressed.
- Everyone Calls Him "Barkeep": The Shopkeeper's real name is never revealed (not even in the backstory described above).
- Gone Horribly Wrong: His experiments to regain his looks could not have gone worse.
- Jerk with a Heart of Gold: In the TV episode. Although grumpy and moody, he still tells Carly Beth how to remove the mask, out of sympathy for her plight.
- Mad Scientist: Quite possible with this guy. If not mad, then at the very least eccentric.
- Multiple-Choice Past: Although, as noted above, he is given an official backstory in the "Goosebumps Collector's Caps Book", the episode has it so that he created the mask to cover up some kind of natural ugliness.
- Reed Richards Is Useless: The pioneering this guy did in growing artificial, lifelike faces would have ended disfigurement, had he taken the time to publish his discoveries.
A living Halloween mask, one of several created by a scientist.
- Antagonistic Offspring: For the unnamed Shopkeeper, and given the circumstances it's not hard to see why.
- Anti-Magic: As shown in Scream Of the Haunted Mask, the Mask grants its wearer the ability to physically harm and restrain spirits(or at least the ones of past hosts).
- Ascended Extra: 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.
- Back from the Dead: In the television adaption of The Haunted Mask II.
- Clingy Costume: 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.
- Creepy Child: Its hosts are almost always children, and it seems to possess a rather immature mentality. The version in The Movie will be portrayed by an up and coming child actress.
- Cute Monster Girl: Could be seen as this if you think of it as female. A lot of recent fanart just runs with this.
- Demonic Possession: Happens gradually to its unlucky host.
- Enemy Mine: In Scream of the Haunted Mask, when the ghost of its former owner reawakens to wreck havoc, the mask willingly merges with Carly-Beth to take her down.
- Evil Cannot Comprehend Good: The only way to remove it is with a "symbol of love."
- Evil Feels Good: Has this effect on anyone who wears it for extended periods, growing to revel in the sense of power it gives while unaware their personality is being overwritten. One of it's hosts even came back from the grave just to possess the mask's power again.
- Evil Is Hammy: Has plenty of moments of this in the second half of the episode The Haunted Mask II.
- Evil Is Petty: Aside from gaining a proper host, its only other goal seems to be terrifying others for respect.
- Evil Mask: No, really?
- Freudian Excuse: It was kept in a basement for years by its creator as a failed experiment, which probably led to it developing evil tendencies.
- Godzilla Threshold: It's horrifyingly addictive and controlling, but occasionally it can be useful in fighting other evil beings.
- Gone Horribly Wrong: Its origin story is that it was supposed to be a good-looking face to cover up the creator's own ugly one, but it turned even uglier than him as soon as its creator put it on.
- Grand Theft Me: 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.
- Hidden Depths: Generally a near-mindless and sadistic parasite but the ending of Scream seems to imply it really does have feelings of gratitude for Carly-Beth,since she was the only one who showed it anything close to affection.
- I Just Want to Be Loved: Constantly looking for a host that will accept it.
- Latex Perfection: It's actually synthetic flesh.
- No Biological Sex: It's had both male and female hosts throughout the franchise, but given how Carly-Beth is its favorite, one could assume it identifies as female.
- Not-So-Harmless Villain: The TV series has it sadistically manipulating Steve into capturing Carly-Beth so it can re-merge with her. "Scream of the Haunted Mask" reveals it actually caused the death of its former host by getting her trampled by spooked horses. And then that girl rose from the grave as a vengeful, sadistic wraith addicted to its power. There's a pretty good reason this thing is among the more infamous Goosebumps creatures.
- Puppeteer Parasite: Unlike a lot of "evil masks" in horror fiction before it, this one is a living organism all on its own.
- Superpowered Evil Side: Downplayed. While the mask doesn't seem to give its wearer supernatural powers, it does make them more aggressive, daring, and hot-blooded, which actually saves the day on at least two occasions.
- Sealed Evil in a Can: First locked up in the back of its creator's shop, then kept in the basement of Carly-Beth's house.
- Tortured Monster: It's mainly motivated by anger and self-loathing from being "unloved."
- Worthy Opponent: As of "Scream of the Haunted Mask", it seems to regard Carly-Beth as its favorite host.
The formal name for the masks created by the Shopkeeper. 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 Steve's friend Chuck.
- Adaptational Attractiveness: 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.
- Earn Your Happy Ending: 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.
- I Just Want to Be Loved: They even briefly come alive at one point and chase after Carly-Beth, begging her to love and want them.
- Killed Off for Real: 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.
- Tragic Monster: 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.
- What Happened to the Mouse?: They disappear save for two in The Haunted Mask II and in the other sequels they're just not mentioned at all.
A powerful ghost haunting a pumpkin farm from the second half of Goosebumps Wanted: The Haunted Mask. The Grave-Master has the power to control the plants that grow on the farm, as the farm was built over an old graveyard. The Grave-Master wants to drive people away from the land so the souls buried under the ground can finally rest.
- Badass Boast: To Devin.Grave-Master: It's the Night of the Jack-O'-Lantern, Devin. The jack-o'-lantern laughs at death. Are you ready to laugh at death?
- Bitch in Sheep's Clothing: Initially Mrs. Barnes comes off as a friendly, kind woman, but turns out to be the Grave-Master who wants to kill Devin to give her son a friend.
- The Dog Was the Mastermind: Played with in a somewhat funny way. Devin initially thinks Zeus the house cat is the Grave-Master in disguise. It's really Mrs. Barnes.
- Even Evil Has Loved Ones: Mrs. Barnes was hoping to take Devin into the ground with her so her son Haywood would have a new friend, and when Haywood is thrown into the grave by the Haunted Mask, Mrs. Barnes flips out and dives after her son.
- Fat Bastard: Devin described Mrs. Barnes as looking very round, almost as if she was made out of pumpkins.
- Mama Bear: For her son, Haywood Barnes.
- Plant Person: Specifically one who controls pumpkin plants. They say the pumpkin vines on the farm are all connected to a single vine growing out of the grave the Grave-Master lives in.
- The Power of Hate: The Grave-Master's powers were created from the hatred of the souls whose graves were defiled by the farm built over their coffins.
- Voluntary Shapeshifting: It can transform into a human or animal at will.
Note: The main characters of these books recur in the Goosebumps Series 2000 and Goosebumps Horrorland series.
Lizzy and Luke Morris
The main characters of One Day In Horrorland and Return to Horrorland, and the narrators of the Goosebumps Horrorland books Escape From Horrorland and The Streets of Panic Park. Lizzy's family got lost on their trip to Zoo Gardens Amusement Park and discovered Horrorland, where they were almost killed by the Horrors. Ever since, Lizzy and her brother keep getting involved with the Horrors for the sake of stopping their twisted plans.
- Arbitrary Skepticism: Luke laughs at Evan's claims about Monster Blood in Return to Horrorland despite having escaped a theme park run by monsters.
- Ambiguous Disorder: Since Luke can't sit still for a short moment and is rather hyperactive, one can infer he has ADHD.
- Annoying Younger Sibling: Luke, as he is full of energy and enjoys pinching people, particularly Lizzy.
- Baleful Polymorph: Lizzy is briefly transformed into a pumpkin in Escape from Horrorland.
- The Bus Came Back: They return for the Horrorland series, with Lizzy being the POV character in Escape from Horrorland and The Streets of Panic Park.
- Cassandra Truth: 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 The Mole for the Menace and attempted to make the Morrises The Scapegoat. Lizzy realizes they've been trying to fool everyone when she catches Jillian lying.
- Foolish Sibling, Responsible Sibling: Luke's the foolish and hyperactive one to Lizzy's responsible and level-headed one.
- 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.
- Older and Wiser: Although they're only a year older in the Horrorland series, they return to Horrorland to help out the rest of the kids escape.
- Only Sane Woman: Lizzy is considered the "calm one" in her family.
- No Sense of Personal Space: Luke likes to pinch Lizzy and their friend Clay, calling himself "The Mad Pincher." It comes in handy when they realize the "No Pinching" signs in Horrorland were there for a reason...
- Too Dumb to Live: 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.
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.
- Amusement Park of Doom: Horrorland, which is actually the image for that page.
- The Bad Guy Wins: In the TV show. It's implied they actually kill the Morris Family by driving their car off a cliff.
- The Dragon: 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, Byron is this to the Menace.
- Evil Is Hammy: 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.
- HeelFace Turn: 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.
- Heroic Sacrifice: In the TV series, 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 Senseless Sacrifice.
- The Leader: 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.
- Our Monsters Are Different: 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.
- Token Good Teammate: 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.
- Took a Level in Kindness: 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. 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.
- Weaksauce Weakness: Being pinched. Pinching a Horror makes them deflate like a balloon. Subverted in Goosebumps Horrorland, where they're noted as having taken steps to become pinch-proof since the Morris family escaped.
- Would Hurt a Child: In the first two Horrorland books, the TV show, and the video game. 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.
The protagonist of Deep Trouble, Deep Trouble II and the Goosebumps HorrorLand book Creep From the Deep''. 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.
- Ambiguous Disorder: He's very hyperactive and tends to rush into things without thinking them through, has a very vivid imagination, and doesn't seem content unless he's doing something exciting, which might point to mild ADHD/Autism.
- Asian and Nerdy: According to the Horrorland spin-offs, he's Asian American.
- The Atoner: He spends the second half of Deep Trouble trying to make up for getting the Mermaid captured.
- Badass Adorable: Well, "Badass" would be a stretch, but he can still be pretty brave when push comes to shove.

- Big Brother Instinct: He goes into the jellyfish to save Sheena in the second book.
- Break the Cutie: Doesn't last long, though.
- Character Development: 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.
- Cheerful Child: Oh, yes. This is what sets him apart from his successors.
- Crouching Moron, Hidden Badass: By Creep from the Deep, he's definitely earned this title.
- Cloud Cuckoo Lander: In the book's first few paragraphs, he criticizes Sheena for not opening her mind to concepts like the Easter Bunny and Santa Claus.
- Fearless Fool: 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.
- Foolish Sibling, Responsible Sibling: The foolish to his sister Sheena's responsible. He's more adventurous and reckless, while Sheena is more grounded and close-minded.
- Friend to All Living Things: 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.
- Hot-Blooded: See above.
- I Just Want to Be Badass: Billy dreams of being a great explorer and even tries to fight like one a few times. Unfortunately, he's still a little boy facing giant sea-creatures, hardened criminals, or undead pirates, so he spends more time trying to stay alive than actually fighting.
- Mr. Imagination: He frequently has fantasies about being a famous undersea explorer.
- Nice Guy: He's certainly one of the more likable protagonists.
- Nice Job Breaking It, Hero!: Thanks to him: the benevolent Mermaid was captured.
- Related in the Adaptation: In the mobile game Goosebumps: HorrorTown, his yncle is Spidey from Say Cheese and Die.
- Sibling Rivalry: Him and Sheena engage in a prank war in the second book.
- Straw Loser: Averted. Billy avoids most of the characteristics that the other protagonists have. He also plays a lot more of a role in stopping the villain than most Goosebumps protagonists, who's role is usually "be the kid who experiences the weird/paranormal stuff of the month".
The sister to Billy Deep in the Deep Trouble series. She shares Billy's undersea adventures when they visit their uncle.
- Acting Your Intellectual Age: Billy says she never believed in Santa Claus, the tooth fairy or monsters in her closet when she was younger, and often acts more like an old lady than a kid.
- Annoying Younger Sibling: Due to her know-it-all attitude and tendency to condescend Billy, though Billy often pranks her as well.
- Baleful Polymorph: Implied at the end of Deep Trouble II, where she drinks a bottle of what she thought was iced tea to prank Billy with, and then questions if it was the right one, implying it could've been the plankton mixture Dr. Ritter created that turns humans into fish. However, this isn't addressed in the threequel, Creep from the Deep.
- Catch Phrase: According to Billy, "No such thing".
- Foolish Sibling, Responsible Sibling: A rare case where the Annoying Younger Sibling is the responsible one. She finds Billy's daydreams childish and refuses to believe in the existence of mythical creatures as easily as him.
- No Sense of Humor: Downplayed. She is rather serious and disapproves of Billy's daydreams and pranks, but also isn't above pranking him a few times.
- Only Sane Woman: With Billy being more reckless and imaginative and Dr. Deep apparently spending his time at their house playing with boats in the bathtub.
- Sibling Rivalry: Her and Billy engage in a prank war in the second book, with her being amused when she discovers that he played the exact same prank she was going to play on him.
Billy and Sheena's uncle, he's a marine biologist who discovers all sorts of strange phenomena that endanger him, his niece, and nephew.
- Adults Are Useless: He does try to avoid it, though.
- Cool Uncle: Questionable decisions aside, Dr. Deep is a kind man who devotes his life to studying and protecting exotic sealife, and is willing to pass over millions of dollars to do the right thing. Both his niece and nephew clearly admire him and are always thrilled to join his adventures.
- Cloud Cuckoo Landers Minder: He's this for Billy, trying to keep him out of trouble.
- Distressed Dude: Billy and Sheena always have to save him from whatever menace he's disturbed. One wonders how he's able to survive without them.
- Drill Sergeant Nasty: Being stuck on land messes with his mind so much that it makes him shout things like "Billy, stand up straight! Sheena, swab the deck!" Then again, it's Billy describing this, so he might be exaggerating his uncle's quirks.
- Heel Realization: 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.
- Horrible Judge of Character: Attempts to reason with his treacherous assistant Alexander, even after he tried to kill him and the kids earlier that night.
- Meaningful Name: A marine biologist regularly exploring the ocean whose last name is Deep.
- Less obviously, his boat, the SS Cassandra. Like the fabled Greek prophetess, the Deeps know of things that are impossible for most of the world to believe. In fact, this is practically a recurring theme for the franchise.
- Reasonable Authority Figure: He's useless in dangerous situations, but he does try his best to keep the children from danger.
- Reed Richards Is Useless: No, Dr. Deep, selling a freaking Mermaid to a children's zoo isn't a good idea.
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.
- Asshole Victim: 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.
- Big Bad: Of Deep Trouble.
- Faux Affably Evil: He first appears to be a cheerful, hard-working scientist like Dr.Deep, and acts like a Big Brother Mentor to the siblings. Then he steals their new friend so he can sell her for a fortune, casually tries to dispose of them when they get in his way, and throws everything good they saw in him out the window.
- Greed: He screws over the rest of the crew just so he can sell the mermaid for triple the price of what the Zoo was already paying. Even worse, it's implied he expected Billy to do the same thing in that situation.
- Hate Sink: His actions are meant to show Billy and Dr. Deep the dangers of discovery and ambition.
- Humans Are the Real Monsters: He is the first antagonist to have no supernatural qualities or goals.
- Karmic Death: Possible, since he never appears in the rest of the book or its two sequels.
- Lack of Empathy: Has no qualms about betraying his boss and allowing him to be murdered as long as he gets paid.
- Lethal Chef: The mermaid is the only one who can stand his cooking.
- The Mole: We never find out who he was working for, though.
- Nice Guy / Reasonable Authority Figure: Subverted. It's all an act.
- Not So Different: Just as Billy (originally) wanted to use the mermaid for fame, Alexander wants to use her for fortune.
- Only in It for the Money: "The Zoo was going to pay 1 million dollars for this mermaid. But my new boss will pay me 50 million!''
- What Happened to the Mouse?: We never find out what happens to him and his cohorts after the Mermaid attack. Maybe it's better that way.
The protagonist of Be Careful What You Wish For. Samantha is a hopelessly clumsy, socially awkward girl who is constantly bullied by her classmates. After an especially bad day at school, she meets Clarissa, a witch who offers her three wishes in exchange for Samantha helping her find her way.
- All of the Other Reindeer: She's a social outcast in addition to being clumsy. The closest she has to a friend is Cory, who isn't above taking advantage of her and doesn't stick up for her that much.
- Baleful Polymorph: She becomes a bird at the end.
- Be Careful What You Wish For: Well, it is the title of the book. All of her wishes go horribly wrong, either due to poor wording or Clarissa's incompetent magic.
- Butt-Monkey: She's mercilessly bullied both on and off the court, is constantly embarrassing herself due to her clumsiness, and is pressured to play basketball when it's clear she's no good at it. Her home life is pretty depressing too: her older brother makes fun of her and her parents seem distant and don't relate to her that well.
- Heroic BSoD: After her second wish erases everyone from existence. She starts to panic about how she's going to take care of herself, and nearly breaks down crying before she manages to find Clarissa.
- I Just Want to Be Free: Her life is pretty depressing, to the point where she fantasizes early on about jumping on her bike and riding until she leaves everything behind. When she becomes a bird at the end, she's happy, because she's now free from all her problems.
- The Klutz: Because of her tallness. She was pressured to join the basketball team despite being horrible at it due to her clumsiness. This is one of the things Judith picks on her for.
- Meaningful Name: When she turns into an actual bird.
- My God, What Have I Done?: When Judith and Anna get severely ill as a result of her first wish, she's horrified and even worries that they'll die and she'll become a murderer.
- Nice Girl: She has moments of temper, but is one of the nicer protagonists, even showing concern for her bullies when her first wish causes them to become ill.
- No Good Deed Goes Unpunished: When she helps Clarissa find her way to the location she was seeking, she offers Samantha three wishes that all backfire horribly and make Sam's life even more miserable than it was before.
- Person of Mass Destruction: Briefly, when her second wish results in all other life being erased from existence.
- Revenge Before Reason: Arguably what really screws her over. Each one of her wishes is motivated by a desire to pay back Judith, which ends up hurting literally everyone else. By the end, she still wants to hurt Judith and wishes her to have met Clarissa instead of herself.
- Skewed Priorities: When trying to cope with being the only person in the world, she wonders if it's still a crime to steal food from the store in order to survive.
- Throw the Dog a Bone: She actually makes a basket after her first wish, even though she's no better at playing than she was before.
- Trauma Conga Line: Anything that can go wrong for her, will. Her life was horrible even before she met Clarissa.
- Vengeance Feels Empty: Samantha really wants to hurt Judith. Thanks to Clarissa, she gets just that, but it isn't satisfying in the slightest and only makes her own ordeal worse. One could say Clarissa was trying to teach her this, given Sam's unhealthy need to be better than Judith. It doesn't work.
- Walking Disaster Area: Her clumsiness is always causing problems for her, and Judith never misses a chance to make it even worse.
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. She is also the basis of the "Madame Doom" fortunetelling dummy in the Goosebumps Horrorland series.
- Adaptational Attractiveness: 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.
- Adaptational Jerkass: In Goosebumps: HorrorTown, she is a tad more mischevious, screwing over people on purpose, although it's still hard to call her a villain.
- Adaptational Villainy: Appears to be portrayed as a straightforward villain in the 2015 movie.
- Adaptational Wimp / Demoted to Extra: Sadly, she's little more than another mook for Slappy to boss around in the movie.
- Affably Evil: She does genuinely seem to want to help Sam, even offering her an extra wish. It's just that she's horribly incompetent at granting them.
- Because You Were Nice to Me: 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.
- Beware the Nice Ones: She's honestly one of the nicest and most reasonable figures in the Goosebumps universe. She also has powers that will royally fuck up your life and everyone around you, whether she means to or not.
- Beware the Superman: Causing a temporary apocalypse is one of the outcomes if she's on your side.
- Dark Is Evil / Dark Is Not Evil: 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.
- Exact Words: She lives for this trope.
- The Heavy: Samantha is the one making wishes, but Clarissa carries them out, and thus ends up driving the entire plot of the book.
- Jackass Genie: To Judith in the TV show, but this comes across as a Kick the Son of a Bitch moment. When Judith wishes that people from all over would come to admire her, Clarissa turns her into a beautiful statue.
- Karma Houdini: Remains at large by the end of the story, just as capable of making people's wishes backfire.
- Kick the Son of a Bitch: 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.
- Literal Genie: She'd be a Jackass Genie, 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.
- Nice Job Breaking It, Hero!: She invariably screws up Samantha's wishes horribly, such as making her the best basketball player on the team by making all the other players sickly. It gets so bad Samantha eventually wishes they never met.
- Pet the Dog: To Samantha in the TV show, since she genuinely does appear to feel sympathy for her.
- Reality Warper: Quite possibly the most powerful entity in the series, pulling stuff like Turning back time, changing kids into animals, making seemingly everyone on the planet disappear...
- Unwanted Assistance: 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.
Samantha Byrd's main tormentor.
- Adaptational Karma: In the TV show, she wishes that wherever she'll go people will stop and admire her when Samantha wishes that Judith met Clarissa instead. She gets turned into a statue that people stop and admire.
- Alpha Bitch: She's the best player on the basketball team, and never wastes an opportunity to make fun of Samantha's clumsiness.
- Always Someone Better: She's way better at basketball than Samantha, and constantly rubs it in. It's worth noting that Samantha doesn't actually care about basketball that much, only playing because her parents and coach pressured her.
- Brainwashed and Crazy: Samantha's third wish does this to her, causing her to become completely obsessed with her. It gets to the point where Samantha actually prefers the old Judith.
- The Bully: She spends every moment making Samantha's life miserable, both on and off the court.
- Catch Phrase Insult: "Why don't you fly away, Byrd?"
- Dub Name Change: The French version of the book changes her last name to Woodstock.
- Evil Redhead: While not evil, she is basically the secondary antagonist of the book and a malicious bully.
- Green-Eyed Monster: Subverted. Samantha's friend Cory claims that Judith is jealous of her, but Samantha finds this absurd because she doesn't see herself as having anything to be jealous of. She concludes that Cory's just doing a bad job of cheering her up.
- Hate Sink: What makes her even more detestable is that She even gets rewarded for her bullying at the end of the book.
- The Heavy: She's the one really responsible for the conflict, since Samantha wouldn't have been so keen to make wishes if it hadn't been for her bullying.
- Humans Are the Real Monsters: Clarissa is mostly just an incompetent spell caster, while Judith is basically everything wrong with Sam's life and the reason she makes most of her wishes.
- Humiliation Conga: Judith has an interesting few days, thanks to Samantha's wishes. The first wish makes her screw up at basketball, then become deathly ill. The second wish erases her from existence (along with everyone else in the world). The third wish brainwashes her into thinking Samantha's her best friend. None of it ends up sticking, though.
- Insult Backfire: The last time she uses her "Fly away" Catch Phrase, it's taken literally, and Samantha is delighted to do just that.
- Jerk Jock: An uncommon female example, as she is one of the school's best basketball players, and is constantly riding Samantha over how much she sucks at the game (and in general).
- Jerkass: She's determined to make Samantha's life a misery in every way possible.
- Karma Houdini: Aside from briefly getting sick, she never receives consequences for her cruel treatment of Samantha, and at the end of the book, she gets her way while Sam suffers. This is subverted in the TV show.
- Kick the Dog: Everything she does, but ruining Samantha's new shoes really stands out.
- Laser-Guided Karma: In the book, her becoming sick as a result of Samantha's first wish could be seen as this.
- Properly Paranoid: She's quick to notice that Samantha's the only member of the basketball team not to get sick, and accuses her of casting a spell on them.
- Significant Green-Eyed Redhead: She has copper-colored hair and green eyes and is one of the book's antagonists.
- The Sociopath: She delights in making Samantha miserable with no remorse and for no apparent reason.
- Stalker with a Crush: To Samantha, thanks to her third wish. It's ambiguous whether it's platonic.
- Taken for Granite: In the TV episode, she gets turned into a statue as a result of her first wish.
- You Have to Believe Me!: When Samantha accidentally confesses what she did, Judith starts screaming that she's a witch. Given how sick she is, her mother assumes she doesn't know what she's saying.
Note: The main characters of these books recur in Give Yourself Goosebumps Special Edition #2: Return to Terror Tower.
Sue and Eddie/Princess Susannah and Prince Edward of York
The protagonists of A Night in Terror Tower. A brother and sister who are visiting Terror Tower in England, and quickly find out something groundbreaking about themselves.
- Big Sister Bully: Not nearly as blatant as most examples, but Sue occasionally teases her brother for being a wimp.
- Demoted to Extra: The two only appear at the beginning and a few of the endings of Return to Terror Tower, the actual star of which is a Featureless Protagonist.
- Earn Your Happy Ending: After Eddie pickpockets Morgreg's stones, they remember the incantation needed to travel to the future again, and bring Morgred with them so they have a caretaker.
- Face Death with Dignity: In the TV episode, where they decide to face the execution with dignity.
- Jerk with a Heart of Gold: A very downplayed example, as the "heart of gold" far outweighs the "jerk" part most of the time, but Sue is kind of mean to Eddie at times, such as mockingly offering to hold his hand when he seems scared. She's still a decent enough person in general.
- Fake Memories: Morgred planted these in their brains, with a new life and parents.
- Sticky Fingers: Eddie is a master pickpocket, which comes up when he steals the stones Morgred had in order to transport themselves (and Morgred) into the future again.
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.
- Affably Evil: He isn't above throwing money to peasants for helping him.
- An Axe to Grind: Though he doesn't carry it unless he's preparing for an execution.
- Badass Normal: Doesn't have any supernatural powers, but is vicious enough to intimidate the local wizard.
- Bald of Evil: In the book, he's noted as being completely bald.
- Badass Cape: He sports a billowing black cape when first seen in the tower.
- Beard of Evil: Sports one in the TV adaptation, to make him look more intimidating.
- Blood Knight: The lengths he's willing to go to carry out his job are truly frightening.
- Covers Always Lie: The hooded executioner on the book cover looks nothing like the version in the story. A justified example, since he's tracking his targets in a modern time period, and thus being decked out in full executioner garb would just draw attention.
- Darker and Edgier: Look at his cover image and compare it to the rest.
- Determinator: He traveled through time itself just to capture and kill two kids.
- The Dragon: To the unseen evil king.
- The Dreaded: Even the local wizard fears him.
- Evil Sounds Deep: He has a deep, menacing voice.
- Evil Wears Black: Dresses all in black, even before putting on the hood.
- Knight of Cerebus: Ruthless, competent, lacking in any humorous or campy quirks and implied to have murdered Eddie and Sue's parents.
- No-Nonsense Nemesis: Somewhat unusual for these books, he prefers to skip the Evil Gloating and finish the job as quick as possible.
- Obviously Evil: Particularly in the TV adaptation, with the creepy beard and all-black clothes.
- Punch-Clock Villain: The king he serves is implied to be an even bigger monster than he is. Because of this, the people of the kingdom are willing to do anything to save their own skin, so he sees his duty as a necessary evil to get by in his time period. The Golden Ending of Return to Terror Tower reveals that he's Brainwashed and Crazy.
- Red Eyes, Take Warning: On the cover, anyway.
- The Sociopath: Thinks absolutely nothing of his horrific occupation.
- Token Human: Apparently in the 2015 movie. Every other villain has supernatural powers or origins.
- Would Hurt a Child: He's assigned to execute the young protagonists, and doesn't care that they're just kids.
The prince who murdered Sue and Eddie's parents and took over the kingdom.
- 0% Approval Rating: He is a cruel despot who has people tortured and executed for saying negative things about him. It's no surprise nobody likes him.
- Big Bad: Of Return To Terror Tower.
- Disproportionate Retribution: Fail to pay your taxes or say something negative about him? At best you'll be imprisoned and starved. At worst, you'll be tortured and than executed.
- The Evil Prince: Murdered his own brother and sister in law to acquire the throne, and wants his niece and nephew executed so he can ensure that his rule is permanent.
- Evil Uncle: To Sue and Eddie, having had their parents killed and intending to have them killed as well.
- Greater-Scope Villain: Of A Night in Terror Tower, as he is not seen and is only mentioned.
- Humans Are the Real Monsters: One of the most evil Goosebumps villains, and a flesh and blood human.
- Named by the Adaptation: He is unnamed in the original book. He is named Robert in Return To Terror Tower.
- Would Hurt a Child: Sentenced his own niece and nephew to execution and orders anyone who can't pay his outlandishly high taxes to be imprisoned, starved, and tortured regardless of age, including infants.
The royal wizard/sorcerer, who tries to protect the prince and princess by sending them into the future. Eventually becomes their official guardian in the future, dubbed "Mr. Morgan".
- Adaptational Explanation: In the book, it seems odd that he sent them to the future with incomplete memories and didn't try to come with them. The episode explains that he planned to give them complete memories and go with them, but the Executioner interrupted him.
- Adaptational Heroism: Somewhat. While he still is basically a good guy in the book and loves Susanna and Edward, he is willing to hold Susanna and Edward captive in the tower to avoid punishment himself, even going as far as to use his magic to keep them at bay. In the tv adaptation, he offers himself for sacrifice to King Robert in exchange for letting the kids go.
- Dirty Coward: There are signs of this when Morgred refuses to perform the future spell again because the king will have him executed. However, subverted as he also reasons he won't be able to use his magic to help the rest of Britain if he dies.
- Parental Substitute: He poses as Sue and Eddie's uncle and adopts them after they are all brought to the future at the end of A Night in Terror Tower.
- Purple Is Powerful: Morgred has purple eyes, which warns Sue early on that he is very powerful.
- Supernatural Is Purple: Morgred wears purple robes because he's a wizard.
