Note: The main characters of these books recur in Give Yourself Goosebumps Special Edition #2: Return to Terror Tower.
Eddie and Sue/Prince Edward and Princess Susannah of York
Portrayed By: Corey Sevier and Kathryn Short (TV); Mathew Botuchis and Tamara Mello (Audiobook)
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 Brother Bully: Well, Big Sister. 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.
- Terminator Twosome: The heroic part of this book's threesome, trying to escape a dire fate by leaping through time and chased by someone who wishes to being them back to said dark fate.
Lord High Executioner
Portrayed By: Robert Collins (TV); Drew Lamkins (Film); Paul Collins (Audiobook)
"Did you think I wouldn't follow? Did you really think you could escape from me?"
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.
- 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.
- Deathly Dies Irae: His Leitmotif in the TV episodes.
- 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.
- Scarily Competent Tracker: He has no trouble personally hunting down his targets if they escape. When Sue and Eddie lose him in the rat infested sewer and disappear into the crowded city of modern London, he's still able to find them again very quickly.
- The Sociopath: Thinks absolutely nothing of his horrific occupation.
- Terminator Twosome: He is the "Terminator" of the book's threesome, chasing Eddie and Sue through time to make damn sure they are no longer a potential threat to his master.
- 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.
Morgred
Portrayed By: Diego Matamoros (TV); Roy Dotrice (Audiobook)
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.
King Robert
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 that nobody likes him, and that the only reason why he is able to rule at all is because he has had the entire Royal Court magically Brainwashed.
- Big Bad: Of Return to Terror Tower.
- The Caligula: He has no compunctions about killing his subjects for the slightest offense against him.
- 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 Is Petty: Besides having people executed for the smallest of slights, he sent one of his enforcers to hunt down the missing royal heirs, nevermind that they're hundreds of years into the future and were in no position to threaten his rule.
- Evil Uncle: To Sue and Eddie, having had their parents killed and intending to have them killed as well.
- The Ghost: While mentioned frequently in A Night in Terror Tower, he never appeared in it in-person, not even when Eddie and Sue were recaptured by the Executioner. He was not even named, and was more or less a complete non-entity until he finally made an actual physical appearance in Return to Terror Tower.
- Greater-Scope Villain: Of A Night in Terror Tower, as he is not seen and is only mentioned.
- Hate Sink: One of the vilest characters in the entire series. And that's quite a feat, considering he doesn't even appear in his debut book.
- 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.
