The coach and PE teacher at Spooky High.
In Monster Camp, he is one of the camp counselors.
- Asexuality: As revealed in Kale's secret route, he's asexual, and he runs a support group for other asexuals who are uncomfortable with the highly romance and sex-focused world they live in.
- The Atoner: The reason he became a Coach was that he felt ashamed for how his father earned money by selling unhealthy, sugary cereal to kids. It made him dedicate his life to helping young monsters reach their true athletic potential.
- Cat Folk: He's an anthropomorphic tiger.
- Creepy Gym Coach: Actively Averted. Aside from being a little intense (and occasionally just plain wrong) about physical health and wilderness survival, he really does just have his students' best interests at heart. Additionally, it turns out he's asexual, and actually runs a support group attended by at least one ace-aro student who struggles with the pressures to date in school.
- Everybody Calls Him "Barkeep": He's one of the few characters not to have a real name mentioned in the game.
- Good Is Dumb: He has the students best interests at heart, but he's not the sharpest tool in the shed. In one event it is entirely possible to convince him to let the football team snort cocaine to improve their performance.
- Parental Substitute: In the FAMILY secret ending, Scott admits to seeing him as a father figure.
- Non-Giving-Up School Guy: Frequently tries his best to make the students reach their true athletic potential by giving them individual workouts. Much to their chagrin.
- Reasonable Authority Figure: In the SUPPORT GROUP ending, he firmly but not unkindly explains to the player how theyre making Kale feel, and helps them to understand the situation, all while stating that he knows the players actions were guided by ignorance, not malice.
The giant arachnid in charge of Spooky High.
- Exactly What It Says on the Tin: He is a giant spider named... Giant Spider.
- Fantastic Racism: Is a proud, card-carrying anti-robot bigot in the Classic Game's Calculester route. Unlike most of the other characters, he never overcomes this.
- Giant Spider: He is a giant spider.
- The Voice: Although he is a prominent character throughout the game and even acts as the narrator for the teaser trailer, he doesn't have a sprite and as such never actually appears on-screen. You only ever hear what he's saying (and doing) per the narrator.
The little voice in the player's head that narrates their attempts to woo a date for prom.
- Lemony Narrator: He can be quite snarky at times.
- Ripple Effect-Proof Memory: He's relived the same three/six weeks before Monster Prom thousands of times, and remembers most iterations.
- Secret Character: In Second Term, one route has him wanting to be more involved in the story he's narrating, and it can end with him as the prom date.
- Walking Shirtless Scene: Apparently, being the narrator is a valid excuse for wearing nothing but a hat and a speedo. He's also fairly ripped on top of that.
A prince from another dimension that constantly opens up portals to pull your romantic interests to him and tries to start complicated plots.
- Abhorrent Admirer: Becomes this to every character at one point or another.
- Bishōnen: Parodied, he is unfittingly sparkly and charming for the scenario.
- Everybody Calls Him "Barkeep": It's unclear if he even has a name other than "Interdimensional Prince".
- Foe Yay: Invoked: In one event, he is on a Tinder for rivals, in the intention of finding someone with whom he can build a fierce rivalry that will eventually turn in a tense romance.
- Genre Roulette: How his appearances play out. He seems to have come from a different issue and a different way to conquer someone in a different setting every time. Sometimes, he hints at being from a Space Opera, while others, he is in much less danger, one event is specifically him making a The Bachelor-esque game with Liam, Vera, and Polly.
- Green-Skinned Space Babe: "Interdimensional Babe", rather, but the point still stands, with him being an otherworldly being... who mostly just looks like an attractive human with an unusual skin color.
- Hopeless Suitor: Whether a player passes the stat checks in his events or not, the Prince never manages to actually court anyone.
- Long-Haired Pretty Boy: He has blue hair that goes to just below his shoulders, which matches perfectly with his Bishōnen style.
- No Name Given: He is never given an actual name, and is only referred to by his title of prince.
- Polyamory: The "You Do You" update has a route where the player, the Prince, and Dmitri begin a mutual relationship.
- Prince Charmless: He keeps hitting on people, whether they want him to or not, and no matter how many times he's turned down. Most of the time, when the Prince shows up, the students have a reaction along the lines of "not this guy again."
- Real Men Wear Pink: Always appears using military-like very light pink clothing.
- Reality Ensues: One of the standard endings has the story of his servants deposing him and turning his dimension in a democracy because they could no longer handle the fact that their leader is constantly jumping between dimensions to hit on people.
- The Rival: Regardless of who you are or who you're trying to court for a prom date, the Prince is always threatening to take them away from you somehow.
- Something About a Rose: Carries a rose in his hand at all times. For no apparent reason.
- Unusually Uninteresting Sight: He opens portals at random in the school, which don't really faze anyone that much. Some got used enough to just react to him with annoyance rather than surprise.
- Western Zodiac: A complete romantic and a Libra.
- You Gotta Have Blue Hair: Literally blue, which matches his skin.
Miranda's favorite singing-Serf introduced in The Gift Update.
- Actor Allusion: He seems like a perky, friendly guy, but underneath his cheery demeanor lies a much darker persona who's always speaking in a growl and has an affinity for knives. If you're a fan of his voice actor, you're probably experiencing mild Déjà Vu right now.
- Bitch in Sheep's Clothing: He acts like a loyal servant to Miranda, but is secretly plotting to kill her and the rest of her family.
- Expy: Given his coloration, he's basically Flounder... but, just as Miranda isn't your typical cute mermaid princess, with a twist.
- Fake Cutie: While Miranda is present, he plays the part of the devoted pet. As soon as she leaves, however...
- Guttural Growler: To maximize the contrast between his act and his true "grizzled freedom fighter" persona, whenever he's showing the player his true colors, he goes from a high "cute little animal" voice to this in his voice clips.
- Hero Antagonist: In the eyes of the player he is definitely the villain, but if you think about it: All he's really doing is to disperse of a tyrant who's been enslaving and mistreating him and his people for generations.
- Killer Rabbit: He may look cute and cuddly, but you do not want to get on this fishes' bad side.
- Knife Nut: When switching over to his true persona, he's almost always equipped with a switch-blade.
- Punny Name: Miranda most always refers to him by his full name - "Mr. Pheel the Eel". Try saying it out loud.
- Red Eyes, Take Warning: Whenever he shows his true colors, his eyes go from innocent black doe-eyes to pint-sized red dots.
- Villain Has a Point: Should the player fail at preventing his attempt on Miranda's life, he and the other serfs will successfully assassinate her at her own Christmas party. Although the majority of the population is shocked by this, quite a few are also quick to point out that the Vanderbilt family more or less had it coming, considering their poor treatment of commoners.
Second Term DLC additions
A brooding vampire who wants you to join The Dark Side. Doesn't seem to attend any classes, but considers the school to be a good place to recruit members...as well as occasionally antagonize the Coven.
In Monster Camp, he appears as a member of Camp Rival Camp.
- Belligerent Sexual Tension: Likes this kind of relationship, and is implied to be in one (or at least engage in hate sex) with Joy.
- Early-Bird Cameo: He makes a narration-only appearance in the second event of the ANGELBLOOD route, and (depending on what you do) he'll say that he'll come back as a potential love interest. Liam also wears his default outfit during the Halloween event.
- Emo Teen: Proudly proclaims that he cares about nothing and is a self-proclaimed member of "the dark side".
- Evil Laugh: Prone to cracking his stoic face for these after boasts about the supposed terrors of The Dark Side.
- Hidden Depths: In Monster Camp, he shows a surprisingly dorky side when it comes to his sire, Liam. Throughout his secret route, he shows genuine affection towards his pseudo-father, earnestly wanting to make him proud.
- I Banged Your Mom: Apparently, Damien's grandmother is among the people he's sleeping with. When Damien expresses his displeasure over this, Dmitri can't help but dryly sass him over it.
- I Hate You, Vampire Dad: Inverted. He actually adores his sire Liam, but Liam doesn't feel quite the same way. Word of God has it that Liam was in love with (or at least very attracted to) Dmitri when he chose to sire him, but began to hold him at arms' length when Dmitri interpreted his attempt to start an eternal relationship as a literal father/son bond.
- Mr. Fanservice: While nearly all the boys in the game are this to some extent, it's overtly played up for laughs in his case - all his scenes contain mentions of his perpetual shirtlessness, and a lot of his dialogue and voice clips are highly suggestive.
- Noodle Incident: Has some sort of history with the Coven.
- Our Vampires Are Different: He mostly follows the typical dark and brooding aspect found in modern vampires, and he wears a classic cape. He also personally sees his sire, Liam, as a father.
- Polyamory: The "You Do You" update has a route where the player, the Prince, and Dmitri begin a mutual relationship.
- The Rival: Is this to the Coven.
- Suspiciously Specific Denial: He does not have feelings. Especially not hidden romantic feelings for Joy.
- Those Two Guys: In Monster Camp, he's rarely if ever seen without Morty. Seems to have a thing for this dynamic, as in both of his hidden routes he's romanceable alongside another character: the Interdimensional Prince in Monster Prom and Liam in Monster Camp. Ironically, despite the heaps of implied attraction between them, he can't currently be romanced with Morty.
- Walking Shirtless Scene: His default outfit comes without a shirt, and one of his dislikes is wearing t-shirts.
- White Hair, Black Heart: Proudly a member of the dark side and has white hair.
A fairy therapist.
- The Cutie: Even though her methods of doing so are...unusual, she genuinely wishes to help the Slayer get over her anger issues and is even willing to sacrifice herself to revive her, should the Player fail in the last stat check.
- Expy: Of Navi. She even quotes Navi's Catchphrase in her dialogue.
- Unwanted Assistance: Her therapy seems to entirely consist of siccing violent beasts on her patients. It's a good thing her patient in the game is the Slayer, with the player providing support.
Introduced in the Second Term DLC, they're a group of cultists who worship Z'Gord and have not adapted to the fact that she is now a fanfic-loving teenager named Zoe.
- Bumbling Dad: After the player sets them on the road toward coming to terms with their god's new identity as a mostly-normal schoolkid, their collective attitude toward Zoe starts to take on an air reminiscent of doting parents trying to reconnect with their estranged teenage daughter.
- Cool Mask: They all wear white masks bearing Zoe's green third eye.
- Cult: One that worships Z'Gord/Zoe.
- Hypocritical Humor: In one event, when they try to come up with a theme song for Zoe, one idea is rejected because it blatantly rips off the Animaniacs theme. They then proceed to give you the song they settled on...which is a blatant rip-off of the Steven Universe theme.
One of Miranda's sisters, who commands the Merkingdom army. She appears on one of Miranda's secret routes.
- Blood Knight: Leads her kingdom's army and carries a giant meat cleaver with her at all times.
- Cool Big Sis: Though she can act like a Big Sister Bully at times, she does try to help Miranda find a purpose in life.
- Early-Bird Cameo: First made an (unnamed) appearance in one of the secret routes, in that she is one of the three merpeople (all of whom are Mirandas' sisters) attending Mirandas' funeral during the failed Assassination route ending.
- Expy: Her eyepatch, Blood Knight and Jerk with a Heart of Gold behavior, position as head of military and even a lot about her physical appearance is reminiscent of Undyne from Undertale.
- Eyepatch of Power: Wears an eyepatch, with highlights her badassery.
- Royals Who Actually Do Something: She's a princess who leads her kingdom's army. This is actually the drive of the route she appears in; all of Miranda's sisters fall into this category, and she's trying to get Miranda to become one as well.
- Scary Teeth: Some of her models show her with pointy shark teeth.
- Secret Character: The 1 Year Anniversary update added a hidden romance route for Miranda that heavily features her.
- Tomboy with a Girly Streak: Implied; she's a Blood Knight, but she seems to like cute things if the backpack charm attached to her oversized meat cleaver is any indication.
- Warrior Prince: Warrior princess in this case, but she's the commander of the Merkingdom army as well as a member of their ruling family.
- You Gotta Have Blue Hair: And blue scales.
