Beware of spoilers!
MewmansA race of Human Aliens (at least on the outside appearance) originating from a place known as "Mewni". They are known for their affinity for magic, their fondness of corn, and their hatred of monsters. The mewmans are ruled by the Butterfly family, a matriarchal dynasty that is continued by a long line of powerful mage queens.
- Believing Their Own Lies: They truly believe that the monsters are barbaric and chaotic, despite those stories being fabricated by their queens. This story was passed down from generation to generation until Star discovered the truth.
- Bigotry Exception: The mewmans hate all monsters except for the royal Pony Head and Lucitor families, who had been allies of the Butterfly queens since Queen Solaria's time. This is shown in "Starfari", where a racist shopkeeper welcomes mewman customers yet cruelly drives away any monster who wants to buy his wares, only to learn that one of the monsters is a Lucitor and tries to placate an irritated Tom. Tom later admits in "Is Another Mystery" that despite being a wealthy prince, he's still a monster by mewman standards, and hides his tail so he wouldn't be subjected to more bigotry than he already has.
- Bizarre Alien Biology:
- In "Mewberty", Star, due to the eponymous condition, develops purple hearts all over her body, and an increased attraction to boys. Before long, she transforms into a six-armed butterfly-like creature, and starts cocooning random boys in a purple substance she sprays from her hands. She returns to normal, but with tiny butterfly wings on her back. In "Game of Flags", it's revealed that the butterfly transformation is not a one-off thing; Star's mother can assume the form at will and without losing control, indicating that eventually Star will be able to do the same.
- "Game of Flags" also shows that Star's Uncle Lump had his body cut off a year earlier, and simply had his head attached to a horse's body with no apparent problem. He gets decapitated again over the course of the episode and is merely annoyed at having lost another body.
- The headmistress of St. Olga's, Miss Heinous, has club symbols appear on her cheeks after she displays anger. A strong dose of brainwashing makes these vanish again. It's eventually revealed Heinous is a Monster/Mewman hybrid, which comes with its own list of this trope...
- Boomerang Bigot:
- The mewmans hate monsters, yet their queens can turn into a butterfly-like creatures.
- It's shown they consider humans weak, and even laugh at the idea of a human joining the knighthood, but they clearly forget that they are descended from humans.
- Bright Is Not Good: They usually wear bright-colored clothes, and use bright-colored magic. They started the war against the monsters.
- Broken Pedestal: Anytime their queens reveal themselves to be less than perfect, the mewmans get very upset. As a result, the Butterflys have to keep defying this trope by bending themselves over backwards just to make them happy.
- Creature of Habit:
- Estrella's chapter in The Magic Book of Spells implies that mewmans in general hate change, which explains why she was a very popular queen despite dedicating herself wholly to art. Glossaryck called them "extremely boring".
- It's also implied in Jushtin's chapter that they were appalled by the idea of having a male ruler in a matriarchy, despite Jushtin's mother, Queen Skywynne, wanting him to succeed her and become a good king. They pressured her into having a daughter until Skywynne gave in and got pregnant with Solaria.
- Didn't See That Coming: As implied in The Magic Book of Spells, no one predicted that Queen Skywynne's firstborn child would be a boy, hence Jushtin's name as "The Uncalculated". Once Jushtin was born and named heir to the throne, the mewmans immediately started pressuring Skywynne to give birth to a daughter, despite her having high hopes for her son.
- Double Standard: Mewni is strictly a matriarchal society, meaning that women have more power than the men. This is mainly due to biological prowess since women are quite strong with magic, and have the ability to turn into powerful butterfly creatures that men do not have, making them More Deadly Than the Male. In rare circumstances, men can have magical abilities but it's weak and unfocused, as shown when Marco tried to use the wand. Men can be recognised as royalty but they can never be king, no matter how dire the circumstances are. The best they can be is a royal consort who can give the Queen a successor, and even if they prove themselves to be competent leaders, a king can never be recognized without the power of a Queen. The women of Mewni have full control of marriage, meaning if she chooses to dissolve the marriage then that's the only choice that matters.
- Entitled Bastard: They expect their rulers to attend to their every need, keeping them comfortable and worryfree no matter how much effort it takes, and become deeply angered whenever said rulers do something they don't like, or show themselves to not be utterly perfect.
- Fatal Flaw: The mewmans are traditionalists and won't accept any form of change, no matter how practical it may be. This is best shown with Jushtin and Solaria, as Jushtin had the makings of a great king but Mewni couldn't accept him since their tradition stated that only women can rule. They badgered Skywynne into having a daughter, who turned into a harbinger of Mewni's darkest era due to her race war with the monsters.
- Another fatal flaw is their laziness. They expect their queens to solve all their problems and when things don't go their way, they have absolutely no idea what to do with themselves. A prime example of this is when they ask Moon what to do even though she's no longer queen.
- Fantastic Racism: They hate monsters for being different from them. They consider them either dangerous or just plain gross and disgusting. They were also the ones responsible for taking the monsters' lands away from them, and naturally they tried sanitizing this. Star, Comet, and Eclipsa are among first mewmans to try breaking out of this tradition. They seem to have a low opinion on humans as well.
- Forever War: The war against the monsters has been going on for centuries, with the reason changing from queen to queen. The ultimate cause was from the mewmans annexing the monsters to conquer their land, but it's also shown that even when the Mewmans actually do try to make peace, some monsters such as Toffee refuse to accept it and perpetuate things.
- Gender-Restricted Ability: Magic is generally something only mewman women can use; males wielding magic is treated as a rare occurrence, as Jushtin the Uncalculated was the only male mage in history. It's also stated in ''Star and Marco's Guide to Mastering Every Dimension that only mewman girls can go through mewberty and become butterfly-like creatures. It was assumed that this ability lies only in the Butterfly family, whose queens are powerful mages until it's revealed that Festivia and her descendants are not "true" royalty, revealing it's not strictly for royal bloodlines.
- Holier Than Thou: Deconstructed. The Mewmans generally see themselves as the superior species, and look down on other races because of their xenophobia; even Tom admits that he still gets dirty looks despite his wealth and his family's alliance with the Butterflys. The monsters resent them for this, which created a Forever War as both sides try to defeat the other, with no true resolution in sight. The Mewmans also hold themselves up to such a ridiculously high standard that they utterly refuse to accept changes, such as Skywynne's attempt to make her son Jushtin heir to the throne because she saw great potential in him as a mage King, as well as co-existence with monsters to the point where one of their Kings participated in the Magic High Commission's plot to erase the hybrid Meteora from existence.
- How the Mighty Have Fallen: Mewni, after being a mighty civilization for centuries, ends up having fallen after the Butterfly Kingdom fell to ruin in "Conquer", with its proud people having become refugees. "Down By The River" shows Moon having started a foundation of what's about to be a new civilization for them.
- Human Aliens: Mewmans look like humans, but they're aliens from another dimension. The alien aspect is emphasized in the episode "Mewberty". Season 4 reveals that they're actually descended from humans, who traveled to Mewni from Earth and were changed by exposure to magic.
- Humans Are the Real Monsters: The Mewmans believe that the monsters are the aggressors, but what they know were actually lies told by the Butterfly queens as anti-monster propaganda. The mewmans themselves took most of what they have by force and treat monsters poorly even when they haven't done anything. The human part is more pronounced when it is revealed that they descended from humans; the Kingdom of Mewni's foundation was pretty much an (unknowing) Alien Invasion.
- Human Outside, Alien Inside: Mewmans look entirely human, but at least the ones affected by magic have some Bizarre Alien Biology.
- Insectoid Aliens: They actually have butterfly-esque physiology but they maintain a human appearance. The butterfly form is only shown with their royals.
- I Reject Your Reality: Another of the Mewmans' biggest flaws. Granted, the Queens used propaganda to portray themselves as wise, benevolent rulers, but it's perhaps because of this propaganda that the Mewmans refuse to see the royal family as less than perfect. If a Queen tries breaking tradition or encouraging them to change their ways, they freak out and go against them.
- Lazy Bum: According to The Magic Book of Spells, Mewmans generally expect their rulers to handle all the important matters and keep the kingdom stable, while they do nothing except go about their day-to-day lives, preferring not to concern themselves with anything else. This caused no end of frustration, anger, and weariness for the Queens, with Skywynne spontaneously dipping down and outright destroying a dimension with her magic out of rage towards her subjects' lazy and ungrateful behavior.
- Long-Lived: Mewmans in general can live for centuries, but they do age and get old; it just takes longer than normal humans.
- Lord Country: The Kingdoms of Mewni are all named for the royal families who rule them (or the other way around), such as the Mewni's capital Butterfly Kingdom, the Johansen Kingdom, Cloud Kingdom of The Ponyheads, the Pigeon Kingdom, etc, except for the Waterfolk Kingdom, ruled by the Kelpbottom Royal Family.
- Matriarchy: The mewmans are ruled by a long line of wise and magically powerful Butterfly queens. Queen Skywynne attempted to buck tradition by naming her son, Jushtin the Uncalculated, her heir in hopes that he would become a good king, but her subjects didn't like that and pressured her to have another child until she gave in and became pregnant with Solaria the Monster Carver. Jushtin was shortly forced to supersede his claim to the throne in favor of her sister, which Skywynne deeply regretted but pretended to rejoice in public.
- More Deadly Than the Male: Female mewmans are the dominant sex in Mewni, as they are more potent with magic, and are the only ones who can undergo mewberty to gain a butterfly-like Super Mode. Because of this, only queens can rule Mewni. Male mewmans using magic is considered rare; Jushtin the Uncalculated is the only male Butterfly who can use magic, yet is much weaker compared to his mother, sister, and niece. Skywynne's chapter in The Magic Book of Spells explains that she attempted to subvert this by encouraging Jushtin's potential with magic, hoping he'll become a "mighty magic wielder" like her. But the public didn't like the idea of having a male ruler who can use magic in a matriarchy, so Skywynne was shortly forced to take it back and teach magic to her daughter, Solaria, instead.
- My Master, Right or Wrong:
- The mewmans are utterly loyal to the Butterfly queens, but will freak out if their matriarchs turn out to be less than perfect, much to the detriment of some queens like Skywynnenote and Moonnote . Appropriately, Star learns about this in "Face the Music":Star: Mom! I... I didn't realize this would happen. I thought they wanted to know the real Star Butterfly.
Moon: They don't, Star. They just want to believe that you're a perfect, little princess. And sometimes, the truth is dangerous.
- This also comes into play during season 4: When Eclipsa forbids them from harming monsters, they obey her command - even if they're not happy about it in the least.
- The mewmans are utterly loyal to the Butterfly queens, but will freak out if their matriarchs turn out to be less than perfect, much to the detriment of some queens like Skywynnenote and Moonnote . Appropriately, Star learns about this in "Face the Music":
- Noble Bigot: Not all the mewmans are villains; they can be racist, xenophobic, and sexist (as implied with the public's reaction and treatment of Jushtin the Uncalculated), but they are still well-intentioned.
- Our Fairies Are Different: They are distinctly humanoid in appearance but their queens can enter a super form that resembles a fairy.
- Realpolitik: Despite its prejudices against foreign species, Mewni will form political alliances with beings just as inhuman as so-called "monsters" if it benefits them (especially with powerful magical beings or other kingdoms that have lots of money).
- Straw Character: Mewmans hate anything that breaks their traditionalist, perfectionist standards - they refused to accept Jushtin as their future King because of his gender, despite his great potential in leadership and magic, and pressured his mother, Queen Skywynne, into having a daughter. They refused to accept Meteora because she's half-Monster to the point where one of them participated in the Magic High Commission's plot to legally erase her from existence. They also refused to accept Star's antics, disgusted with "the real [Star Butterfly]" and losing faith in the royal family because of the possibility of them keeping secrets from their subjects. As Moon explained to Star in "Face the Music", they only expect her to be a perfect little princess because they don't want to acknowledge that the Queens and their heirs are flawed like everyone else. Is it any wonder why Saint Olga's School For Wayward Princesses existed?
- Strength Equals Worthiness: The leaders of Mewni are chosen through their power with magic. Queens are the governing leaders because women are more potent with magic than men. Jushtin the Uncalculated was the first male Butterfly to become heir to the throne because his mother, Skywynne, saw great potential in him as a mage King, but the Mewmans absolutely refused to give him a chance because he was born a boy, and pressured Skywynne into superseding her son's claim and having a daughter instead. This resulted in Jushtin having lesser innate magic, as well as essentially being written out of history despite his own accomplishments.
- Transplanted Humans: "Meteora's Lesson" and "Mama Star" show the first Mewmans came from Earth through portals that go through the Magic Realm. Overlaps with Transhuman Aliens, as exposure to magic is likely why their biology and abilities that distinguish them from humans.
- Undying Loyalty: In season 4, a large portion of the Mewmans are still loyal to Moon (to the point of still calling her "Queen") due to a combination of their resentment for Eclipsa, and their inability to get by without constant guidance.
- The Unfair Sex: Mewmans are matriarchal, so naturally, one of the aspects of society women control is marriage. This means that the husband has no say whatsoever if the wife decides to dissolve their relationship.
- Vast Bureaucracy: There are such numerous experts in Mewni's government that Star had to keep going door to door to find the Monster Expert. These so-called experts don't seem to serve any real purpose other than handling matters that are below Moon's pay-grade.
- Vicious Cycle: The war between mewmans and monsters has been going on for centuries, with mewmans attacking the monsters and the latter responding in kind, further fueling anti-monster prejudice. Only Butterfly family members such as Star, Comet, Eclipsa, and Jushtin have somewhat broken the cycle by interacting with monsters on a respectable, even friendly level.
- Written by the Winners:
- Popular belief among mewmans is that their ancestors were desperate immigrants who fought off the aggressive monsters in self-defense. Star was not happy to discover that the mewmans were the actual aggressors, not the monsters. Added to that, the first people of Mewni did not have pursuits of any kind, but rather were clueless human explorers who were doused in magic that made them lose their memories, and happened across the land by dumb coincidence.
- In regards to Jushtin the Uncalculated, his accomplishments weren't celebrated or officially recorded at all, despite all the good things he did for Mewni. This suggests that the mewmans wanted to forget that a Butterfly male was ever considered liable for the throne.
Members of the Mewni Court
The main servant of the Butterfly household with a stuffy attitude.
- Black Shirt: Manfred joined the new Solarians, and unlike many others he remained loyal to Mina over Moon even after the mind-warping affects of their powers had dissipated.
- Fantastic Racism: He's openly expressive regarding his bigotry towards monsters. When Eclipsa holds a breakfast event inviting her Mewman and monster subjects, he has the latter eat on the floor as if they were animals.
- Gossipy Hens: A male example according to Moon.
- Green-Eyed Monster: Manfred has always been jealous that he and the other servants are never given the chance to dine on fine china.
- Jerkass: Along with being an open racist, he also participated in the "Butterfly Follies" event that ridiculed Star and River, his former employers.
- Nice Hat: Manfred wears a cyan and light purple striped hat with a yellow feather on top.
- Put on a Bus: For the first half of season 4, Manfred gets turned into stone after eating Yada-Yada Berries meant for Eclipsa. He gets better by "Cornonation".
- Sinister Schnoz: Manfred has a pointed, long nose and is revealed an open, racist jerkass who willingly joins Mina's Solarian soldiers, and still sides with her even after all the magic is gone.
- Taken for Granite: He turns into stone after eating oatmeal laced with Yada-Yada Berries. He does get back to normal but the event was traumatic enough that he quit his job.
- Trauma Button: After getting back to normal, the event was rather traumatic for him, so he quit his job and if anyone mentions it, he refuses to talk about it.
- You Gotta Have Blue Hair: He has reddish-purple hair.
The new songstrel of Mewni, who creates a Princess Song about Star on Song Day.
- Aw, Look! They Really Do Love Each Other: The fact that he married Foolduke despite their constant bickering and creative differences in The Battle For Mewni. They both do admit that they enjoy arguing with each other, so at least they have a base for marrying.
- Belligerent Sexual Tension: He and Fool Duke can't stop bickering during 'The Battle for Mewni'; then the next time we see them, they're getting married.
- Cannot Keep a Secret: The second half of his Princess Song only serves to blab some massive secrets to the entire kingdom of Mewni.
- The first secret is that Star lost the Book of Spells and Glossaryck, and that her parents have been keeping that fact hidden from both Mewni and the Magic High Commission.
- The final part of the song is dedicated to Star's secret crush on her best friend Marco. The song's penultimate line practically goes out of its way to be completely unambiguous about the big reveal. Not only did Star not ask him to include any such thing in the song, she didn't even know he'd done so. Indeed, there's no indication that she even told Ruberiot at all about this particular secret. He basically figured it out on his own and wanted to sing about how obvious it is.Ruberiot: Star Butterfly is in love with her best friend... and his name is Marco Diaz.
- Comic Trio: With Foolduke and Mime Girl.
- Didn't Think This Through: Performing a song that reveals the dark secrets of the royal family did not get the raucous applause he expected.
- Dude, Where's My Respect?: Ruberiot is aghast when his audience boos his frankly amazing rock ballad. Of course, they have every right to be upset considering what he just told them.
- The Gambling Addict: "Escape From The Pie Folk" has him develop a gambling problem, and doesn't know when to give up.
- Hipster: Gets into lengthy arguments with Foolduke about which of them makes "real art".
- Innocently Insensitive: Telling everybody about Star's crush on Marco without asking her was not cool. Doesn't matter if everybody could see it.
- La Résistance: Forms one with Marco, Foolduke, and the Mime when Butterfly Castle is taken over by Ludo. Bonus points for actually naming it "La Résistance".
- The Last DJ: He refuses to be a hack like the songstrels before him, who basically repeated the same Princess Song over and over with the only difference being the princess' name. Star's initial refusal to work with him under the assumption that's he's going to be just as insincere as his predecessors really gets to him.
- Nice Hat: A dark grayish-blue hat with a light blue feather on top.
- Not So Different: As it turns out, he and Star both have the same low opinion of the previous Princess Songs, viewing them as recycled, formulaic, saccharine lies that paint the image of an unrealistically perfect girl to be idolized.
- Official Couple: Officially married to Foolduke, as of "Booth Buddies".
- Plucky Comic Relief: Forms a comic relief squad with Fool Duke and Mime Girl.
- The Rock Star: The bulk of his Princess Song has him as one.
- Saying Too Much: His Princess Song reveals a lot of unnecessary details to his audience that cause immense trouble. Not to mention making some of them seem more sinister than they actually were. Worst of all, he put in a verse that even Star didn't give him permission for. He just loves to gossip.
- Shipper on Deck: He ships Starco, to the point that he wrote the ending of the song to be about Star being in love with Marco.
- Small Role, Big Impact: His actions in his debut episode not only cause the entire kingdom of Mewni and the Magic High Commission to distrust the royal Butterfly family, but they also inform Marco for the first time that Star is in love with him.
- Take That, Audience!: In "Face the Music". He's a representative of the aggressive "starco" shipper. As shown by his over-deliverance of Star's crush in his rock ballad. This deliverance also made her friendship with Marco very awkward.
- Too Dumb to Live: Apparently he didn't realize that blabbing royal secrets in song form would be seen as a bad thing.
- Unwitting Instigator of Doom: His song designed to show the people of Mewni "the real Star Butterfly" also inadvertently reveals that the king and queen were implicit in a cover-up surrounding Glossaryck's disappearance. He also outs Star's secret crush on Marco, driving a wedge between them.
- Vitriolic Best Buds: He gets into constant arguments with Foolduke but comments later that they enjoy arguing. However, they do genuinely hate each other. Naturally, they get married in "Booth Buddies".
- Warts and All: His intention with the Princess Song for Star is to show the real her. In practice, the "warts" are best left hidden, since the mewmans liked to believe that the Butterflys are perpetually wise, benevolent, and graceful.
The jester of Butterfly Castle.
- Ambiguously Brown: Like a lot of Mewman characters, Foolduke has brown skin but is not from any country on Earth.
- Aw, Look! They Really Do Love Each Other: The fact that she married Ruberiot despite their constant bickering and creative differences in The Battle For Mewni. They both do admit that they enjoy arguing with each other, so at least they have a base for marrying.
- Belligerent Sexual Tension: She and Ruberiot can't stop bickering during 'The Battle for Mewni'; then the next time we see them, they're getting married.
- Big Damn Heroes: In "Escape from the Pie Folk", she shows up in her hot air balloon to save Marco and the Butterfly family from the Pie Folk.
- Black Sheep: It is revealed in Escape From the Pie Folk that she herself is a member of the Pie Folk, but she herself doesn't share their love for the criminal lifestyle that defines them, and was what ultimately led her to leaving Pie Island and to go live in Mewni instead. This arguably makes Foolduke the most decent member of Pie Folk descent in the entire show outside of Star Butterfly.
- Comic Trio: With Ruberiot and Mime Girl.
- Dark-Skinned Blonde: She has brown skin and blonde hair.
- Defector from Decadence: see Black Sheep
- Everything's Better with Monkeys: Had a pet monkey that King River inadvertently threw out a castle window.
- Happy Harlequin Hat: Wears a purple jester cap and enjoys her jokester job.
- Hipster: Apparently views her buffoonery as a medium for social commentary. Also gets into lengthy arguments with Ruberiot about which of them makes "real art".
- Hollywood Tone-Deaf: During her duet with Ruberiot, although to be fair they were both making the song up on the spot.
- The Jester: Her job is apparently using "the guise of the buffoon for social commentary".
- La Résistance: Forms one with Marco, Ruberiot, and the Mime when Butterfly Castle is taken over by Ludo. Bonus points for actually naming it "La Résistance".
- Nice Hat: A blue jester's hat with golden bells on the ends.
- Official Couple: Officially married to Ruberiot, as of "Booth Buddies".
- Plucky Comic Relief: Forms a comic relief squad with Ruberiot and Mime Girl.
- Tomboy: Has the occupation of a goofy jester and is not above quarreling with Ruberiot.
- Tomboyish Ponytail: She has a short ponytail going through her jesters hat.
- Tomboyish Voice: Her voice is very raspy.
- Vitriolic Best Buds: She gets into constant arguments with Ruberiot but he comments later that they enjoy arguing, even if they genuinely hate each other. Naturally, they get married in "Booth Buddies".
- White Sheep: She comes from a family of liars and thieves and resents them for it.
The Butterfly family's resident mime.
- Comic Trio: With Ruberiot and Fool Duke.
- Everyone Hates Mimes: Inverted. Everyone describes the mime as an artistic genius even though she doesn't do anything that impressive. She's also the only one of the three that they all agree has artistic vision, with Ruberiot and Fool Duke deriding each other's work constantly.
- Impossibly Awesome Magic Trick: Repeatedly pulls a set of scarves from her throat and swallows them back up. Even uses this trick to rappel up a wall and as a trampoline to catch Ruberiot.
- Informed Attribute: Played for Laughs. Other characters repeatedly describe the Mime as an artistic genius.
- La Résistance: Forms one with Marco, Ruberiot, and Fool Duke when Butterfly Castle is taken over by Ludo. Bonus points for actually naming it "La Résistance".
- Nice Hat: She wears a purple beret.
- Nice Girl: Isn't self obsessed or egotistical like Ruberiot and Fool Duke.
- Plucky Comic Relief: Forms a comic relief squad with Ruberiot and Fool Duke.
- Suddenly Voiced: Speaks exactly one line to tell Marco to get the key.
- Token Good Teammate: While Ruberiot and Fool Duke aren't evil, Mime Girl is by far the nicest member of the trio and the only one who doesn't have a massive ego, showing genuine delight whenever people compliment her skills in a totally innocent fashion.
- Vocal Dissonance: Has a jarringly low and grating voice.
- The Voiceless: Communicates everything through miming, and has only spoken once.
A "Knight of the Wash" who runs Mewni's royal laundry, and takes his job very seriously.
- Badass Beard: He has a thick but well-groomed beard and mustache.
- Bunny-Ears Lawyer: The laundry of the Butterfly Castle is always guaranteed to be done with him around, even if he's not that right in the mind.
- Closest Thing We Got: In "Divide", Star seriously considered sending him after Meteora, as he was the only one in the castle to actually show some initiative.
- Dashing Hispanic: He has dusky skin and a thick Spanish accent.
- Heroic Lineage: Lavabo comes from a long line of Knights of the Wash.
- Knight in Shining Armor: Lavabo dresses in full plate armor, even though the only thing he seems to fight are stains.
- Meaningful Name: "Lavabo" means "(bathroom) sink" in Spanish, a fairly fitting name for a Hispanic-coded character obsessed with cleanliness (though he cleans laundry rather than hands).
- Serious Business: Lavabo takes his job as a Knight of the Wash very seriously indeed, refusing to let a garment go unwashed under his watch.
A knight's squire who competes with Star and Marco in Quest Buy. She later becomes a knight herself.
- All for Nothing: She spent years to become a knight, but abandons her position after a few days to live in the Neverzone.
- Bitch in Sheep's Clothing: At first, she acts nice and friendly when conversing with Marco, but later turns out to be nothing more than a competitive jerkass.
- Boyish Short Hair: As befitting her tomboyish behaviour.
- Fiery Redhead: A textbook example. She's a redhead with a temper.
- Freudian Excuse: It seems the harsh nature of her squire training is what made her so bitter and competitive.
- Hypocrite: She attacks Marco for deciding not to become a knight, and also says he "cheated" by spending time in the Neverzone. When Marco offers Higgs a trip to the Neverzone, she Jumped at the Call, and ends up staying just because she doesn't get to keep the muscles she builds there upon returning to Mewni.
- Jerkass: Is a major jerk to both Marco and Star. Never mind the fact that the latter is technically her boss, though she's just about the same age as Star.
- Jerkass Has a Point:
- In "Trial by "Squire", Higgs isn't wrong when she says that Marco's status as a squire, while not for being Star's boyfriend, was indeed out of nepotism.
- In "The Knight Shift", this is subverted when she just proves to be a hypocrite. She calls Marco a "cheater" for his work with Star and his training in the Neverzone, and says he thinks himself too good to be a knight. Marco, however, points out that the single-minded attitude of the knights only hurts themselves, and even offers the knights a chance to train in the Neverzone. Higgs takes it instantly. To make matters worse, when Higgs returns to find her muscles gained from years of training vanish outside the Neverzone, she decides there's nothing left for her in her old knight life on Mewni, and despondently returns to the Neverzone.
- I Just Want to Be Badass: Higgs' lifelong goal was to become a knight of Mewni. Upon meeting Marco, who was made a squire by Star, she was bitterly jealous of his good fortune, and of his superior fighting skills. When Marco offered her a trip to the Neverzone to train they way he did, she completely abandons her old life as a knight, and moves there permanently just because she feels that isn't worth losing the muscles she gained from training.
- Inferiority Superiority Complex: Her interactions with Marco hint at her having one of these towards him. When Star makes Marco her squire, Higgs is bitter over Marco being given what she worked to achieve and she derides him as a "wannabe" who doesn't deserve to be a squire. After they both reach knighthood, and she finds out that Marco is a far more skilled warrior than her from years of training in the Neverzone, she derides him as a "cheater", who thinks he's better than the other knights.
- Put on a Bus: She decides to move to the Neverzone permanently at the end of "The Knight Shift". The Neverzone has an extremely accelerated flow of time, so unless she changed her mind offscreen, Higgs likely died (of old age if nothing else) before an hour has passed in Mewni.
- Rank Up: She's is knighted alongside Marco in "Knight Shift".
- "The Reason You Suck" Speech:
- In "Trial by Squire", when Marco asks why she acts like a jerk, she responds with this:Higgs: Listen, wannabe, you think it's easy being a squire? All of my waking hours I'm weaving chain mail, sharpening swords. I'm always at my knight's beck and call. I've even learned how to polish armor in my sleep. But what did you do to earn this job? Oh, nothing. It was handed to you because you're the princess' boyfriend.
- She tries this less successfully in "The Knight Shift" on Marco, who just throws one back at her:Higgs: It's 'cause the dude's a lousy cheater. Got the squire job handed to him, then he spends years training in that Neverzone place? He thinks he's too good to be a knight.
Marco: If you all could for one second think about the world from someone else's point of view, none of this would've happened. You want to train up in the Neverzone, be my guest.
- In "Trial by Squire", when Marco asks why she acts like a jerk, she responds with this:
- Right for the Wrong Reasons: Higgs rightfully assumes Star making Marco her squire was an act of nepotism, but her reasoning was off. She thinks Star did due to mistakenly thinking Marco is Star's boyfriend, when really Star did out of both pity and wanting her friend back.
- Significant Green-Eyed Redhead: Coupled with her being on the same age range as Marco and Star, her green eyes and red hair end up making her noticeably distinct from her friends Baby-Man and Old Guy, and she becomes Marco's most prominent rival among the squires (and later knights).
- Tomboy: The short hair, the aggressive behaviour...
- Underestimating Badassery: She believes Marco to be a newbie who became squire by his connections to the princess. She is unaware of his various fights with monster armies alongside Star, as well as their battle with the Lint Monster.She learns this the hard later on.
- Wounded Gazelle Gambit: When Marco trips her, she pretends to be badly hurt, with two black eyes. Star feels sorry for her, but Marco doesn't buy it. He was right.
- Youthful Freckles: It fits with her red hair.
Mewni's royal monster expert.
- Condescending Compassion: She is one of the few Mewmans that doesn't explicitly hate monsters and wants their preservation. However, she doesn't consider them to be intelligent beings and treats them how one would treat a lab rat. Not to mention the fact that she blows up a dam to try and isolate them on an island.
- Cool Old Lady: Despite her views on monsters, she is a rather enthusiastic and charismatic old lady. After changing her view on monsters, she is not afraid to rip off her clothes and live in the wild.
- Fan Disservice: She rips off her clothes at the end, to the shock of everyone around her. Star even covers the eyes of Buff Frog and the tadpoles.
- Fantastic Racist: Zigzagged, at first she said that she wants to stop the discrimination that the monsters receive. However she studies them like they were wild animals rather than people, and also believes that Mewmans and Monsters can't really coexist and the solution to their problem is isolating them in an artificial island.
- Fantastic Science: A zoologist who studies monsters, although she should be treating it more like anthropology if she wanted it to be accurate.
- Ignored Expert: Until Star visited her, she apparently didn't meet any person from the royalty that wanted to end monster discrimination.
- Going Native: She is so impressed with the monsters' teamwork in stopping the flood she accidentally started, she decides that more Mewmans should live like the monsters... starting with herself.
- Know-Nothing Know-It-All: Dr. Goodwell is considered a monster expert, but doesn't really know anything about monsters, nor does she even see them as fellow sentient beings. To the extent that she literally assumes that the monster town is a bunch of "naturally occurring formations that almost look like buildings", because it's inconceivable to her that they would actually know how to build their own houses.
- No Celebrities Were Harmed: She's a parody of Jane Goodall (and the second depiction of her as insane, no less).
- Smart People Wear Glasses: She is a monster expert (at least according to herself) and wears them, through apparently she isn't Blind Without 'Em. She gets rid of them some moments when she is considering to live like a monster in the end.
- Underestimating Badassery: Jelly continually underestimates the intelligence of the monsters.
- The Xenophile: A rather negative version mixed with Loving a Shadow: Goodwell has interest, sympathy, and even admiration for monsters, but her prejudice completely blinds her to what they're actually like. She is impressed by their every action, but only because she judges them by standards of animals, and still misses their humanlike intelligence. After they save their own village using organization and cooperation, her assessment merely changes to thinking them Noble Savages that the Mewmans should emulate.
- You Are Number 6: Goodwell tags monsters with numbers and only refers to them as such.
First mentioned in "Game of Flags", Lord Mildrew is a Mewman noble who knew Queen Moon from when she was a teenager.
- Beauty Is Bad: Downplayed. He's handsome and well-meaning, but he's overly emotional and condescending towards the people he tries to help.
- Chekhov's Gunman: His name was brought up in "Game of Flags" as a potential replacement husband for Moon, which she soundly rejected. "Moon the Undaunted" and "The Battle for Mewni" reveals why Moon chose River instead of him: Mildrew was overly emotional and condescending towards Moon, treating her like a grieving daughter who lost her mother, making her choose between war and peace with the monsters, and never respecting her decisioins.
- Condescending Compassion: While his attempts to console Moon were well-meaning, he didn't let Moon voice her own opinions and treated her like a grieving daughter the entire time. This is largely why Moon eventually chose to marry River, who respected and supported her, despite him being a Johansen.
- The Ghost: He was mentioned in "Game of Flags" as a potential suitor for Moon to replace her husband River with. He later made his full appearance in "Moon the Undaunted" as one of the nobles who worked in close proximity to Moon when she became queen.
- Vague Age: Since mewmans can live for centuries, it's implied that he's somewhat still in his prime physically, as Etheria brings him up to Moon as a potential husband replacement for River.
MonstersA heterogenous group of creatures inhabiting Mewni, composed mostly by anthropomorphic beasts and insectoids. Although they are first introduced as an antagonistic race for our heroes, later we learn that they are actually the outcasts of Mewni, with most of them living in extreme poverty and suffering the oppression and racism of the mewmans.
- Always Chaotic Evil: In earlier seasons, the monsters are depicted as an antagonistic race of violent, uncultured barbarians, and the reason for the mewmans' war with them was that they attacked first when settlers were trying to settle down. It's gradually deconstructed; there are indeed truly evil monsters, but their actions end up fueling anti-monster prejudice against the good monsters, who become villainous out of desperation and revenge. Both the mewmans and their Butterfly matriarchs also see themselves as objectively superior to other races; since the monsters don't fit their standards, they're either killed, cruelly oppressed, or "helped" by mewmans in order to keep them under their thumbs. With a lot of suffering like this, it's no wonder the monsters often act so violently towards mewmans. This isn't helped by monsters who flat out refuse to accept any offer of peace, even if it's completely genuine like Comet's attempts.
- Beast Man: A lot of monsters are basically humanoid animals, and can even be identified by the specific animal they resemble.
- Cycle of Revenge: The monsters constantly attack the mewmans either out of self-defense, retaliation, or revenge for their deeds, to which the mewmans respond in kind. In the end, it benefits nobody, as both sides continue to suffer.
- Dark Is Evil: They are distinctly darker and non-human. It's eventually subverted with the discovery that it's not that simple, as the mewmans were the ones who actually started the war.
- Dark Is Not Evil: Not all the mosters are evil and while they are dark and non-human looking, it is revealed that they are not always evil with Buff Frog doing a HeelFace Turn and becoming one of the good monsters.
- Deconstructed Character Archetype: Of Always Chaotic Evil. They were initially depicted as nonhuman barbarians who lived for violence and death, opposed by the benevolent and orderly Butterfly queens. It was eventually discovered that the monsters only acted the way they did because first the mewmans forcibly took their land, then cruelly oppressed/killed them, then sanitized their own actions to make themselves look good. In reality, the monsters either fought in self-defense, retaliation or for outright revenge for what the mewmans have done to them.
- Divine Conflict: Downplayed in that while neither side is godlike, the Butterfly family is led by their women, who are powerful mages, while the monsters are led by Toffee, who has a very powerful healing factor that makes him very hard to kill. Meteora had a combination of both Butterfly and monster abilities. She had peak physical abilities and lesser innate magical abilities, like soul stealing and magic absorption.
- Evil Cannot Comprehend Good: Due to the war with the mewmans, they have a good reason to harbor a grudge against them. So when the likes of Comet try to negotiate for a peaceful outcome, they don't hesitate to align themselves with her killer.
- Fantastic Racism: While the subject of a lot of it, it's shown some monsters harbor racism back at the Mewmans and even when Mewmans like Comet genuinely try to make peace and give them racial equality, these monsters won't accept it and continue hostilities, perpetuating the cycle. Toffee is one such monster.
- Forever War: The reasons for the war against the monsters vary from queen to queen of Mewni, it started when the mewmans came to monster-infested land and conquered it with advanced weapons and armor. That said, some mewmans such as Comet genuinely have tried to make peace and bury the hatchet, but monsters such as Toffee refuse to accept it and continue hostilities.
- Frog Men: They are powerful leapers and start life as tadpoles just like regular frogs.
- Had To Be Sharp: They had to be resourceful after the mewmans annexed them.
- He Who Fights Monsters: They initially wanted their land back but they now just as bad, if not worse, than the mewmans.
- Lizard Folk: Known as Septarians and one of the prominent monster races due to their long-standing grudge against the Butterfly Family. They are infamously known for their powerful regenerative abilities and nigh-indestructibility; making them both ageless and nearly immortal. According to the The Magic Book of Spells, they hate magic and are known to be vengeful monsters. As a result, a majority of them were against the mewman-monster peace treaty, even going so far as to start preparing for war, recruiting monsters outside their species with similar mindsets.
- Noble Savage: They're seen as savage by the Mewmans but they are quite civilised and Globgor is recognised as royalty. The Mewmans just annexed them and caused a centuries-long race war
- No Name Given: Very few of them are actually named. Buff Frogg is actually called Yvgeny Bulgolyubov, then there's Toffee, Ludo, and Globgor.
- Not Always Evil: At first had the monsters of Mewni as the titular forces of evil, whom the protagonists Star and Marco regularly have to fight. Initially, Star believes they are all evil by nature (as do her family and entire species called Mewmans), until the episode "Lobster Claws", which explores the possibility that this may not necessarily be true. "Mewnipendence Day" details the history between mewmans and monsters, revealing that the Mewmans essentially slaughtered and drove the monsters out of their own land. Star doesn't take this well. As a result, she begins to show more kindness and understanding towards the monsters, starting with Buff Frog. In the second season, Buff Frog becomes a viewpoint character, which, combined with his acquired fatherhood, really helps humanize him as a decent monster struggling to make ends meet given the lack of non-evil opportunities available to the monsters.
- Not So Different: Even Buff Frog concedes that monsters and mewmans are two sides of the same coin, petty jerks who need to grow up.
- Organic Technology: They lack the technical advancements of the mewmans, some species of monsters have racial abilities that are proven to be medicinal. For example, Princess Spiderbite's wound was healed by Slime Monster.
- Revenge Myopia: The mewmans annexed them from their land and they have been locked in a Forever War with each other ever since. In the case of Comet, things are just too far gone between each other for the chance of peace.
- Screw This, I'm Outta Here!: With the growing tensions between mewmans and monsters, a majority of monsters have left Mewni. Buff Frog tells Star that he and the monsters will only return once Star is made the queen.
- In season 4, it seems like a lot of monsters have returned to Mewni (or come out of hiding) because of Eclipsa's more monster-friendly politics. However, it's implied that Buff Frog is not one of them.
- Screw You, Elves!: They have a justified hatred towards the Mewmans, a fairy-like race.
- Semi-Divine: Each species of monster have varying degrees of powers and abilities. Toffee's people are the closest to Physical Gods due to their nigh-powerful healing factors.
- Trapped in Villainy: Many "villainous" monsters are just desperately looking for ways to survive, and the mewmans refuse to give them any chances due to racism, their belief in their own superiority, and anti-monster propaganda generated by the Butterfly queens. It isn't helped by the fact genuinely evil monsters have actively attempted to destroy any possibility of peace and racial equality out of hate, such as Toffee murdering Comet when she was on the verge of doing so.
- Vicious Cycle: The war between mewmans and monsters has been going on for centuries, with mewmans attacking the monsters and the latter responding in kind, further fueling anti-monster prejudice. Only Star and Eclipsa have somewhat broken the cycle by interacting with monsters on a respectable, even friendly level.
- Well-Intentioned Extremist: They just want their land back from the mewmans, who slaughtered their kind without provocation. Now, they just want revenge.
- Winged Humanoid: Some of the monsters possess wings and use them for flight.
- Written by the Winners: The monsters were demonised by the mewmans. The Magical High Commision was also involved.
- Your Terrorists Are Our Freedom Fighters: They initially appeared and were depicted as barbarians attacking the mewmans. They were actually the original inhabitants of Mewni, they were simply fighting for liberation and in retaliation for the mewman attacks. In fact, they wanted the wand because they saw it as a power-balance to take back their home.
Eclipsa's monster husband, and Meteora's father. He is a feared, powerful monster that used to feed on mewmans before Eclipsa convinced him to go vegetarian.
- Adorkable: Despite his monstrous appearance and reputation, Globgor is actually a big softy with various eccentricities and a vivid imagination.
- Aerith and Bob: Though Eclipsa and Meteora are rather exotic names, they relate to real life elements, so they're not completely uncommon. The same can't be said for a name like Globgor.
- Amazon Chaser: He gives one reason he loves Eclipsa in in "Ready, Aim, Fire":"[Eclipsa] is terrifying. I love her so much!"
- Ambiguously Evil: Much like his wife, initially it's not clear if he's actually evil or just looks terrifying. At first, his only known 'crime' is eloping with Eclipsa and we know him to have been a loving husband and father. The Magic Book of Spells shows that he was well-respected among the monster community and he thought Toffee's genocide plan was going too far. Once we see more of his legacy, he increasingly looks like an outright Evil Overlord: Globgor celebrated violence against mewmans (including eating them) and actively cultivated an image as a ruthless warmonger. Then the audience finally see him in person, and Globgor shows no signs of hostility or resentment, and even seems understanding of those who want him to stay imprisoned, but also has a rather flippant attitude to those he's harmed (to the point of making a tasteless joke about eating miners). Ultimately, whatever his past misdeeds were, he seems to have put them far behind.
- The Atoner: He does regret the bad things he's done in the past, and is willing to answer for them, but doesn't want Eclipsa or Meteora to suffer for it.
- Barbarian Longhair: Downplayed, since his hair from the looks of it doesn't reach past his back, but his hair was long and messy, and he was knock for being quite violent whenever he got angry.
- Big Red Devil: He's enormous, red skinned, horned, four eyed and has a tail his daughter has inherited. However, he's apparently not a literal demon, at least not one connected to Tom's people.
- Breath Weapon: The tapestry of his forces attacking Spiderbite Village depicts him breathing fire, which is either summoning his minions or appearing close to them. Whether this is artistic license or not remains to be seen. "Cornonation" shows him creating powerful gusts of wind, but no flames as of yet.
- Bruiser with a Soft Center: He will fight for his family and takes on the Magic High Commission by himself. There's no doubt that Globgor has his heart on his sleeve and is openly romantic with Eclipsa.
- Cat Folk: Globgor has some feline features. As shown by his striped fur, pointed ears, claws, fangs and tail.
- Chekhov's Gunman: The gibberish Glossaryck keeps spouting throughout Season 3? It's actually Glossaryck fulfilling one of his more unusual life goals, challenging himself to say nothing but the name of Eclipsa's monster husband for a whole year.
- Childhood Friend Romance: The Magic Book of Spells reveals that Globgor and Eclipsa have been secretly friends since they were kids. The two would leave messages around the kingdom for each other to find, and eventually they fell in love, married, and had a daughter.
- Cold Turkeys Are Everywhere: Downplayed. While he does miss the taste of mewman, making various off-color jokes about eating mewman miners in "The Monster and the Queen", it is unlikely that he will give in to any temptations any time soon.
- Dark and Troubled Past: Various accounts from the Magic High Commission and The Magic Book of Spells certainly implies this. Globgor was possibly a ruthless Monster Lord who cherished violence against Mewmans and even ate them before turning over a new leaf when he met Eclipsa, and becoming a vegetarian. However, since their relationship wouldn't be approve by Mewni, they ran off and elope, having a daughter, Meteora. Unfortunately, he and Eclipsa were crystallize by Rhombulus for apparently only being married to each other and having a Mewman-Monster daughter. And then their daughter was taken from by the Commission.
- Dark Is Evil: Zig-zagged. The Magic High Commission and most of Mewni believe he was evil, Eclipsa and certain monsters believe he's not, and the situation is rather unclear at the moment, but there's no doubt in the fact he was known as the "Prince of Darkness" before he became the King of Monsters.
- Dark Is Not Evil: Moved to this after he fell in love with Eclipsa and becoming The Atoner for his past.
- Disappeared Dad: To Meteora. He (with Eclipsa) was crystallized by Rhombulus and Globgor was unable to be there for his daughter.
- The Dreaded: Mewni knows him as a man-eating plucker of limbs and the "prince of darkness", and the murals and artwork all over his own fortress celebrating his atrocities doesn't help his case. How much of his reputation is accurate following his relationship with Eclipsa has yet to be seen, though it seems that he misses eating mewmans a little.
- Dude, Not Funny!: He has a dark sense of humor and likes to joke about attacking people. However, Eclipsa has to remind him that it's not wise to joke about his reputation.
- Earn Your Happy Ending: After being crystalized, separated from his family and nearly dying after reuniting with them, he finally gets to live in peace with them in the finale, after Mina and her army are depowered and defeated.
- Even Evil Has Loved Ones: Well Ambiguously Evil, at any rate. The way Eclipsa talks about him makes it clear he loved her as much as she loves him, and he presumably felt the same way about Meteora.
- Even Evil Has Standards: While Globgor is Ambiguously Evil (including eating Mewmans), The Magic Book of Spells showed he thought Toffee's plan to commit genocide to Mewmans was going too far.
- Everyone Has Standards: In "Cornonation" he overpowered Star and was very close to crushing her within his palms, but instantly lets go when River yells at him that she's his daughter. Even after all this time, he won't make River suffer the fate he (nearly) did.
- Extra Eyes: He has four.
- Face of a Thug: Even if you want to make the argument that Globgor wasn't evil, and assuming he hadn't the things to give him the bad reputation he has as a plucker of limbs and Mewman-eater, you can't help but agree that his face doesn't exactly convey the feel that he's trustworthy.
- Foil: Serves as one to Wrathmelior, the mother of Tom. They're both massive, red-skinned, horned demon-like entities with multiple eyes, with weird names compared to their spouse and children's relatively more normal names, who fell in love with a Mewman and gave birth to a Mewman-Monster hybrid. Unlike Wrathmelior, however, Globgor had his wife and child taken away from him, and he wound up being crystallized and imprisoned inside his Monster temple.
- Happily Married: With Eclipsa. The two deeply love each other, to the his wife was willing to abandon her throne for him, and since Eclipsa never had a bad word to say about him, it's implied, and later confirmed, he was a kind husband.
- HeelFace Turn: It's implied he really did used to be a Mewman-eating warlord, but eventually abandoned such practices and became a better person because of his love for Eclipsa.
- Hero of Another Story: Globgor's definition of a hero is still yet to be seen due to the Ambiguous Situation in Season 4. His story of being abused by the mewmans and eventually finding love with Eclipsa may be a story of interest. Especially if he's a heroic underdog or a manipulative villain.
- Hidden Depths: The Prince of Darkness has a phenomenal singing voice and even harmonizes with Eclipsa when they sing together. He and Eclipsa are also revealed to be masterful culinary artists, having baked a disturbingly lifelike cake resembling a Mewman as a gift for Star and Tom.
- Horned Humanoid: Has a pair of short horns.
- Hot Skitty-on-Wailord Action: Similarly to Tom's parents, it's unknown how exactly Eclipsa was able to produce viable offspring with Globgor, who is a good 40 feet tall. Eclipsa was willing to give some details in "Total Eclipsa the Moon", but Moon preferred not to know that. He was later confirmed to be able to change his size, which would explain how...certain things are possible.
- Huge Guy, Tiny Girl: Eclipsa could use his forearm as a seat, and a size comparison in the fourth season shows Eclipsa looking barely bigger than his finger. This is justified, however, as he has the ability to shift size.
- Interspecies Romance: He's a monster, specifically a Size Shifter, who fell in love with Eclipsa, a Mewman, who abandoned Mewni for him.
- Karma Houdini Warranty: While he did become a vegetarian for Eclipsa, he never faced any consequences for previously eating Mewmans and allegedly destroying the Spiderbite Kingdom. However, he would eventually be separated from his wife and daughter and be imprisoned in crystal for the next three hundred years.
- Kick the Son of a Bitch: Supposedly, he ate King Shastacan. Given that Shastacan had kidnapped his daughter and sold her off to St. Olga, it's hard to see Globor as doing anything but give the bastard what he deserved.
- The Kingslayer: Alleged to have eaten King Shastacan, although Shastacan was just a consort (like all of Mewni's kings).
- A Lighter Shade of Black: While he is Ambiguously Evil, The Magic Book of Spells reveals there was something out there even he feared: the Septarians. As in the same race as Toffee. So much so that his worry about their leader Seth amassing an army lead to Eclipsa creating the spell used by Moon on Toffee.
- Love Across Battlelines: He fell in love with Eclipsa, whose mother was hellbent on exterminating all monsters.
- Monster Modesty: He seems to wear only a speedo for an outfit. Judging by "The Monster and the Queen", he'll dress fully for at least formal occasions.
- Make My Monster Grow: Just like his daughter, Meteora, he grew to a clearly massive size in his final battle with Rhombulus before his crystallization. Didn't help him beat him, however, as the rest of the tropes can attest.
- Maligned Mixed Marriage: Eclipsa left Mewni with him because of Mewmans' prejudice against monsters.
- Monster Lord: He's been called "the monster king" and at the very least lead an army of monsters.
- Nice Guy: While its implied that he's done some legitimately bad things in the past (like eating Mewmans), upon being freed from his crystal, he instantly tries to run away to keep his family safe and actively avoids hurting anyone. He's quick to apologize when he traps Star in his hands during their fight as well as when he almost hits the crowd of mewmans and monsters with his tail, even while he was in the middle of being attacked by the Magic High Commission.
- Not So Different: To River, both were childhood friends to their wives, are openly affectionate towards them and are strong family men who will risk their lives to protect their children. They were also disapproved of by their wives' families, Globgor for being a monster and River for being a Johansen. In "Cornonation" this is the reason why River votes to have Globgor freed.
- Papa Wolf: King Shastacan took his wife and infant daughter away from him. Globgor's response was to eat Shastacan. When he escapes in "Cornonation" he immediately tries to put as much distance as possible between himself and his family to protect them from danger. When he learns that they are being held hostage by the Magic High Commission he offers to be crystallized again in exchange for ensuring their safety. When Rhombulus goes ahead and starts crystallizing Eclipsa anyway, he fights the entire Commission and only stops his rampage when he spots Meteora in danger.
- Red and Black and Evil All Over: Zigzagged. Globgor is a red-skinned monster who wears black speedos, and was known as the "Prince of Darkness" before ascending to king. However, he's more Ambiguously Evil and Eclipsa (who is also Ambiguously Evil) was Happily Married to him and The Magic Book of Spells shows he wanted to stop the war between Mewmans and monster. However, he was noted to eat Mewmans before becoming a vegetarian.
- Red Baron: "The Prince of Darkness", "Crusher of Skulls", "Plucker of Limbs".
- Red Herring: He is built up as the likely Big Bad of Season 4, only for all expectations of him to be subverted when it's revealed that he's actually a very sweet and gentle guy, and just wants to live in peace with his family.
- Red Is Violent: He's a purplish red monster with slightly darker-red markings, and before turning into a vegetarian, he was known to have at least rampaged the Spiderbite village and eaten King Shastacan, as well as other Mewmans.
- Reformed Rakes: While it is implied that he was beloved by the monsters he ruled, he was very much The Dreaded to mewman-kind, eating them usually his go-to solution to any mewman problem with various sagas and works of art dedicated to his many horrifying accomplishments. After marrying Eclipsa, he has become an Adorkable Vegetarian Carnivore who prioritizes the safety and comfort of his wife and daughter more than he does himself, revenge against the Magical High Commission and the people of Mewni the last thing on his mind.
- Roaring Rampage of Revenge: Considering the utterly terrifying monster that he was thought to be and his tragic past full of injustices against him and his loved ones, most everyone, show characters and the audience alike, expected him to do exactly this upon his freedom from his crystal prison — only for the trope to be thoroughly subverted: when he's freed, Globgor immediately stomps away from the Monster Temple, scaring everyone into thinking that his rampage has started. However, he was actually fleeing the kingdom in self-imposed exile because he didn't want to endanger Eclipsa and Meteora by provoking the citizens of Mewni with his presence. Even when Rhombulus attempts to reimprison Eclipsa, Globgor takes the pacifist route first, tearfully begging him to stop — only using violence as a last resort when it became readily apparent that there was no other way to save his wife.
- Satanic Archetype: The Spiderbites see him as one, and portray him as a hulking devil who would breathe fire on hundreds of innocent people, and also gets frozen in ice, bringing to mind Divine Comedy imagery, but flips to Satan is Good when it shows that he is a genuinely good person and wants to make up for the misdeeds of his past. Eclipsa also defends Globgor, insisting that matters were much more "complicated" than most people believe and the bad things her husband had done were for a reason.
- Scary Teeth: Globgor has a mouth full of razor-sharp teeth, which tends to make his smiles rather terrifying.
- Sealed Badass in a Can: Turns out he has been crystallized solid for all those years.
- Shapeshifter Default Form: His approximately eight-foot form seems to be his true size, as he shrank down to it from giant-sized when hit with a Power Nullifier.
- Sinister Schnoz: Globgor has a long nose and has an Ambiguously Evil nature.
- Size Shifter: He can make himself as big as a building or small enough to sit on his wife's shoulder, and can change the size of different parts of his body. The Magic Book of Spells specifically calls his species "size shifter".
- Strong and Skilled: To contrast Meteora's Unskilled, but Strong. While he doesn't have magic like Meteora, he more than makes up for it with skill and raw physical strength. He is a master at leveraging his Size Shifter powers to keep his enemies off-balance, transforming from a tiny imp to a colossal titan in mere seconds. He can even shift parts of his body separately, giving him even more options in combat.
- Slasher Smile: He's almost always portrayed like this, not that he can help it and it's what Eclipsa found attractive about him. His smile looks more innocent in the Box of Truth hologram, meaning the tapestry room may have been propaganda similar to the dramatization of Toffee's defeat by Moon. Having a mouth full of razor-sharp teeth also tends to make any smile rather terrifying.
- To Serve Man: Eclipsa admits he sometimes ate Mewmans before she convinced him to stop (and become a vegetarian).
- Turn the Other Cheek: Globgor is quite forgiving, likely out of an acute awareness of his own misdeeds. Globgor does not blame the Mewmans for hating him, nor does he blame the Magic High Commission for crystallizing him. He was only willing to strike because he saw his wife and daughter in danger and wanted to defend them. Nonetheless, he was willing to turn himself in once he's sure his family is safe.
- Unexplained Accent: Globgor speaks with an ambiguously Hispanic accent due to his actor, similar to Buff Frog's unexplained Russian accent.
- Unwitting Instigator of Doom: The Magic Book of Spells reveals that it was Globgor's idea for Eclipsa to leave with him even though she had reservations about this since she would be betraying her kingdom if she left, but Globgor pointed out she was already doing so by loving him. He wanted Eclipsa to stay with him and his monster army for a brief period and "save both [their] kingdoms". Unfortunately, this lead to the both of them being crystallized and their daughter, Meteora, being disinherited and sent away.
- Vegetarian Carnivore: Eclipsa convinced him to turn into a vegetarian after spending who-knows-how-long eating Mewmans.
- Vocal Dissonance: From Globgor's appearance, size, and all of the stories about him, it's easy to expect him to have an intimidating, threatening voice. His voice is actually soft, normal-sounding (not to mention inexplicably Spanish), and far from intimidating, and stays that way regardless of his current size. His voice does change a bit when he grows or shrinks, but still sounds much less threatening than his daughter's did.
- Waistcoat of Style: His usual attire when he's not wearing a loincloth.
- Walking Spoiler: Nothing in the show until Season 3's finale even hints the dude's still alive. Even his name gives away that Glossaryck isn't just spouting gibberish for Season 3.
- The Worf Effect: As powerful as he's made out to be, he was still crystallized by Rhombulus in the end.
- Your Size May Vary: In his first physical appearance, he is absolutely enormous. Much bigger than how the Grandma Room tapestry or the Truth Box hologram portrayed him. It was eventually confirmed that he is a Size Shifter. Since his stance and expression when frozen indicate he was in the middle of a fight against Rhombulus (presumably in a failed attempt to protect his wife and daughter), he would've had good reason to maximize his stature.
- You Sexy Beast: He's not exactly handsome in the conventional sense outside from his definite muscle mass, but Eclipsa clearly thinks so given how she blushes upon seeing the Box of Truth's hologram of him. Janna agrees basically the second she sees him. It also doesn't hurt that when it comes to romance he has a ton of game — and a shockingly beautiful singing voice.
One of Ludo's minions, he spies on Star and informs Ludo when to attack her. Starting in Season 2 he becomes an ally of Star.
- Acrofatic: A stout fellow, but an incredibly agile one.
- Action Dad: Season 2 has him proving he can still kick ass despite now being a father to his adopted tadpoles.
- Anti-Villain: Always held shades of this, as it becomes increasingly clear that the Mewnians are not particularly benevolent towards monsters rather then the other way around, but especially in the second season where he is a single father who is attempting to feed his twelve children.
- Awesome Moment of Crowning: At the end of "Starfari", Star dubs him Mewni's new Royal Monster Expert.
- Character Development: In the beginning of season 1, Buff Frog was a loyal servant to the dastardly Ludo. After being fired from Ludo (thanks to Toffee's manipulations), receiving some kindness from Star, and becoming a father, Buff Frog refuses to work under Ludo again and slowly becomes more and more friendly to Star and Marco.
- Combat Pragmatist: Knocks out Ludo when his guard is down when they reunite in Season 2 and tries to steal his wand to stop the miniature despot's scheme.
- The Dragon: To Ludo in Season 1 as he was his most trusted ally and second in command, but he was fired and now refuses to work with him.
- Embarrassing Tattoo: When he was allied with Ludo, he had an angry image of him with the word "forever" tattooed onto his chest which is under his fat. He kept this hidden and only revealed it to Star and Moon in order to distract her for Star.
- Enemy Mine:
- He and Star aren't exactly friends, but he's willing to aid Star in saving Marco if it means his tadpole children get to have a roof over their heads, and Ludo was just too untrustworthy. Eventually they do become friends.
- He teams up with Meat Hook to escape Ludo's underground hideout in Season 2.
- Even Evil Has Standards: While they might not like each other, he and Toffee agree that spying on Star in the bathroom was crossing a line.
- Family Man: He happily adopted the tadpoles Ludo gave him as a bribe in the Season 1 finale and in Season 2 we see him working harder to maintain his family.
- Friendly Enemy: Has apparently upgraded to this by the time of "Starsitting", entrusting Star with looking after his tadpole babies while he's at work, but not without threatening them if they don't do a good job.
- Good Costume Switch: After his HeelFace Turn, he ditches the tunic with the Avarius crest for a plain one and loses the spiked shoulder pads. Ironically, he's also added a skull to the previously plain belt.
- Good Parents: He is very devoted and caring to his children.
- The Heavy: He does a lot of the work, but Ludo calls the shots.
- HeelFace Turn: As of Season Two, he and Star consider themselves friends and he rejected an offer to join Ludo's new operation, and he's quit doing evil altogether. Buff Frog really believes Ludo needs to be stopped.
- He Knows Too Much: Toffee manipulates him to get fired after Buff-Frog tries to lead a revolt.
- Husky Russkie: Speaks in this accent.
- I Have a Family: Says as much when Ludo is about to blast him with the wand.Buff Frog: No, please, I am father now.
Ludo: I know that, you idiot! I'm the one who gave you those [tadpoles]!
- The Illegible:
- His handwriting is just a bunch of squiggles. However, it may only be subverted, as his handwriting is very similar to Russian cursive◊, considering Buff is also Russian.
- In "Raid The Cave", he later confirms that he never learned to write properly.
- In a Single Bound: "On The Job" reveals that he can jump extremely high.
- Love Redeems: Becoming the adoptive father of thirteen tadpoles is the starting point, and a constant motivation, for him turning into a more kind and decent monster.
- Mistreatment-Induced Betrayal: Post-"Storm The Castle", Buff Frog refuses to work for Ludo again partly because he realizes Ludo was such a jerk anyways, regardless of the fact that Toffee convinced Ludo to fire him.
- Multipurpose Tongue: Buff Frog can extend his tongue quite a distance, as well as manipulate it to pick up objects or even pick locks. The drawback is that, it might accidentally cause him to swallow the object he's trying to use.
- Mushroom Samba: Due to Star's "Jellybean Hallucination Mist".
- No One Gets Left Behind: He rescues the other monsters after they get trapped by King Butterfly's Ring of Fire, he also goes back for the unconscious Meatfork when escaping from Ludo's Elaborate Underground Base.
- Not So Different: He openly defends Globgor during "Cornonation" stating that he comes off as a big proud papa.
- Number Two: To Ludo. Until Toffee arrived and got him fired. By Season 2, he's gone solo and hasn't expressed interest in going back into Ludo's fold. When Ludo offers him that job again in "Is Mystery", Buff Frog responds with a punch to the face.
- Oh, Crap!: When Ludo hires Toffee.
- Only Known by Their Nickname: As it turns out, Buff Frog isn't actually his name. His actual name is Yvgeny Bulgoyaboff. Even his friends call him Buff Frog, on account of it being easier to pronounce.
- Only Sane Man: The most consistently on-the-ball of Ludo's henchmen (not that it's saying much) and the only one to realize there was something... off... about Toffee.
- Overly Long Tongue: Long enough to reach across a room.
- Papa Wolf:
- After Ludo gives him a bunch of tadpoles in an attempt to bribe him, he happily accepts fatherhood. He helps Star break into Ludo's castle and fight his former colleagues so his children (that he got five minutes ago) will have a better future.
- In "Starsitting", he has Star and Marco babysit the tadpoles. He tells them to take care of his babies... then adds "or else" with a heavy Death Glare.
- Punch-Clock Villain: His status in season 2. There are no non-evil jobs available to monsters on Mewni, and he has a family to feed. Buff Frog struggles with this, because hurting people no longer comes naturally to him. Later on, he stops doing evil altogether.
- Put on a Bus: In "Is Another Mystery" he and his family leave Mewni because the discrimination is too much for them, but he promises to keep spying on the state of affairs for the right time to come back until Star becomes Queen. In "Cornball", Star convinces him to move back because of Eclipsa's reforms and the potential that at least their children can learn from it.
- Redemption Promotion: Zigzagged. He does get a lot more moments of being genuinely competent after his HeelFace Turn, but it's implied he actually already was a very competent warrior and spy even before this, and the reason he was always losing onscreen was because we only saw him facing Star.
- Screw the Money, I Have Rules!: As much as it would put food on the table for his adopted tadpoles, Buff Frog turns down Ludo's offer to be his right hand again, because he thinks Ludo is too dangerous.
- "Shaggy Dog" Story: His investigation into who was stealing the Mewmans' corn in season 2 provides some great world-building, but his illegible writing makes his attempt to warn Star about Ludo's wand pointless and by the time he manages to tell her where Ludo is hiding during the second half of the season, he's long gone. He should have thought this through.
- Smarter Than You Look: Though his broken English (of exactly the type that stereotypically goes with his Russian accent) made him come off as less intelligent, he's the only one of Ludo's minions (including Ludo himself) to have doubts about Toffee. Despite this, he can't express it in writing.
- Stout Strength: While his rotund form doesn't make it immediately obvious, Buff Frog really is as buff as nickname implies. His Super Strength is first demonstrated in "Star Comes to Earth" when he casually rips a streetlamp out of its mounting◊ to swing as a club◊.
- Strange Salute: He extends both arms Nazi style and croaks like a frog. He also has a version where he first extends both arms and then kisses his fingers alternating.
- Token Good Teammate: The nicest and most honourable of Ludo's henchman in spite of his vocation as a spy. Naturally he's the one who makes a HeelFace Turn.
- Top-Heavy Guy: His legs are tiny compared to his arms and torso.
Buff Frog's adopted and beloved children who are a big factor behind his HeelFace Turn.
- Accents Aren't Hereditary: Katrina doesn't show any signs of her father's Russian accent.
- Conjoined Twins: Mikhail and Leo are attached at the tops of their heads.
- The Cutie: All of them qualify for this role, especially Katrina.
- Happily Adopted: They were given to Buff Frog and they couldn't have asked for a more loving father.
- Hidden Depths: As tadpoles, the buff babies would often sneak out to go clubbing.
- Identical Twin ID Tag: Once they're fully grown, the only way to tell Katrina apart from her siblings (aside from Mikhail and Leo, of course) is by her eyes.
- The Leader: Katrina is this for her siblings.
- Like Parent, Like Child: Just like her dad, Katrina is a spy-in-training as she's been able to keep communications with Star when she and her family moved from Mewni. While Buff Frog chastises her for giving away their activity, he can't help but feel proud over the fact that she's been able to do so without him knowing.
- Massive Numbered Siblings: A litter of a dozen tadpoles.
- Strong Family Resemblance: They all bare a strong resemblance to one another.
- Theme Naming: Just like their father, their names are all Russian-coded: Katrina, Boris, Alexi, Anastasia, Dimitri, Anya, Igor, Mikhail, Leo, Irina, Nadia and Sergei.
- Uncanny Family Resemblance: Once they're fully grown, they all look like mini-versions of Buff Frog, but they're his adopted babies.
- The Voiceless: Katrina was the first who learned to talk, but even after the others are old enough to presumably do as well, we still don't hear them.
- What the Hell, Hero?: Katrina's reaction to Star's 'plan' to defeat Toffee.Star: Oh right! I don't have one.
Star: Yeah, planning's not really my thing! I gotta just go for it.
Katrina: That is a terrible plan!
The Avarius family has ruled over the monsters for generations, yet their royal power was thanks to mewman influence; Queen Crescenta Butterfly believed that the monster populace wouldn't take care of themselves without a leader, and promoted the Avariuses' ancestors to Kings and Queens. While they enjoy a lot of privileges, they are technically pawns of the Butterfly dynasty.
- Abusive Parents: While Ludo's family history was highlighted in "The Hard Way", it's confirmed that his parents were cruel to him to toughen him up because they saw him as the runt. They also went on holiday without him which allowed Ludo to lock them out of their own castle by changing the locks and then claiming it as his own.
- Big Little Man: Lord Brudo answers the door by peering out the mail slot, appearing to be the same height as Ludo. When he opens the door, he looks taller while still being relatively short. Then he stops slouching and is shown to be taller than Moon that he can barely fit through the door.
- Bird People: The Aviariuses are humanoid birds with wings for arms with hands at the tips. Too bad Ludo never developed wings.
- Bitch in Sheep's Clothing: Lady Avarius is only nice when she interacts with Moon, but at home, she's horrible to Dennis.
- Blatant Lies: Their claim to Moon that they only treated Ludo the way he did to "toughen him up" rings false later on "Ludo, Where Art Thou", where they treat Dennis terribly (and it is implied they're horrible to all their kids).
- Dark Is Evil: The Avarius children and their parents are depicted with dark, sickly colors, especially green. Save for Dennis, who subverts it, all of them are unrepentant abusers and bullies for Ludo.
- Subverted with a majority of the siblings when their first appearances show them happily working alongside Ludo to restore their ancestral home.
- Domestic Abuse: Lady Avarius has a seeming black eye she can't open, which given how irritable and angry her husband can get it isn't hard to figure out the implication. However, she can open it (so it seems more of a lazy-eye), which among other hints makes it a bit more ambiguous while still hinting this trope.
- Establishing Character Moment: When we first see Lord Brudo, he's very grouchy and rude towards Moon.
- Grumpy Old Man: Lord Brudo is a crabby, washed-up old man.
- Hate Sink: There is nothing to like about Lord Brudo. He emotionally abused his son Ludo in his youth and doesn't care about his whereabouts when he disappears, possibly beats his wife, and treats his son Dennis with fear. These alone make him unlikable. His wife also shares this trope due to treating Ludo and Dennis the same way her husband treated them despite being more polite.
- High Collar of Doom: Lady Avarius has a tall, spiked collar, and she's an unpleasant woman despite being more polite than her husband.
- Impoverished Patrician:
- In The Magic Book of Spells, Queen Estrella the Drafted mentions in one of her drawings that the Avarius family sank their fortunes by investing in the corrupt scratch-and-sniff trade.
- Ludo's entire family, forced to live in a rickety shack since Ludo changed the locks on their castle while they were vacation, then destroyed it (though that was Star's, not Ludo's fault).
- Laser-Guided Karma:
- Ludo managed to turn the tables on his abusive family by locking them out of the castle when they went on vacation without him.
- By the end of "Princess Quasar Caterpiller and the Magic Bell", Ludo, Dennis, and their siblings have rebuilt Castle Avarius, and can now live there together without suffering their parents' tyranny (which leaves Brudo and his wife to live alone in their rickety old shack - a suitable punishment for their awful treatment of their children).
- Matriarchy: The fact that Ludo, as well as his siblings, carries his mother's last name (Avarius) implies that this is the case. Justified, as the matriarchal Butterfly dynasty was responsible for the Avarius family becoming royals.
- Punny Name: One of Ludo's siblings is named Menudo, a well-known dish in Mexico.
- Puppet King: The Avarius family is implied to be a royal matriarchy, due to Ludo and his many siblings sharing their mother's name rather than their father's. This is thanks to the influence from the mewmans, who are matriarchal; Queen Crescenta elevated their ancestors to royalty because she thought the monsters couldn't take care of themselves otherwise. It didn't work, as the current generation of Avariuses are mostly horrible people and the monsters are still in poverty.
- Riches to Rags: Ludo's parents, the lord and lady of his old castle, became exiled to a broken-down shack in the woods because Ludo changed the locks while the rest of his family was on vacation. Now, they're just a bunch of washed up has-beens.
- Theme Naming:
Ludo's "little" brother and the only apparent decent member of the Avarius family.
- Adorkable: He's really tall and imposing, but has the temperament of a teddy bear.
- Basement-Dweller: He's a grown man who lives in his parents' home, and fittingly, they feel he's on the path to becoming a deadbeat. He does move out eventually so he can rebuild their family castle.
- Big Brother Worship: Utterly adores Ludo for locking their parents out of the house and, seemingly, standing up to them.
- Big Little Brother: Dennis is much taller than Ludo despite being younger than him.
- Broken Pedestal: Subverted. He's horrified with Ludo's Sanity Slippage but ultimately maintains his belief that his brother is a hero and does everything he can to help him.
- Face of a Thug: The first few times we see Dennis he has a grimace and Death Glare on his face but he is actually one of the few decent people in his family.
- Hidden Depths: Dennis seems to be rather talented in basketball.
- Morality Pet: Dennis brings out Ludo's more redeeming side.
- Token Good Teammate: The only member in his family who is not abusive towards Ludo.
- The Unfavorite: With Ludo gone, he's the one taking the most abuse in the family. If anything, he may have been the second least favorite of the family, and it's implied by Lady Avarius that he's gotten in trouble many times.
- White Sheep: Dennis is the only one to know about his brother's predicament from presumably watching him and is worried for his mental state. He takes Moon to him hoping she might be able to help him. Bonus points to him being the only one in his family wearing a white shirt.
A monster teenager who's made of slime.
- A Dog Named "Dog": A person made of slime named "Slime". According to The Magic Book of Spells, every member of his species is named "Slime".
- Blessed with Suck: Slime may be able to cure ailments, but his composition renders him unable to manipulate small objects, which keep sinking into his arms.
- Blob Monster: Of the slime variety.
- Distressed Dude: Slime along with the other monster teens end up kidnapped by Mina during Star's party.
- Healing Hands: His slime has the healing properties of aloe vera and can cure most minor injuries such as spiderbites. This becomes one of the reasons why Penelope, along with her parents, develops a fondness for him.
- Interspecies Romance: By season 4 he is in a relationship with Penelope Spiderbite, a Mewman royal).
- Magic Antidote: His slime heals Penelope's spiderbites in only seconds.
- Nice Guy: He's a decent and friendly young man.
- Nice Hat: He wears a purple toque.
- Nigh-Invulnerability: As a creature of Slime, he can handle just about any physical injury and pick up himself back up without issues. That doesn't mean that he can still fear for his life after being kidnapped by Mina.
- Reality Ensues: Having a non-solid body makes it difficult for him to hold on to anything. Such as his phone compact.
- Relationship Upgrade: He ends up in a committed relationship with Princess Penelope Spiderbite in Season 4. He even has the approval of his "in-laws".
- Walking Shirtless Scene: He doesn't wear a shirt or anything to cover his upper body.
A winged monster butler introduced in the fourth season who serves Queen Eclipsa.
- Foil: To Manfred. Both of them serve as the main butler figures to their respective Queens. But while Manfred was a Mewman who was a snobby racist, Archibald is a monster and is a pleasant fellow in comparison.
- The Jeeves: He's Eclipsa's closest servant and is eager to help her with any of her queenly duties.
- Our Gargoyles Rock: His appearance resembles that of a gargoyle.
- Satellite Character: He doesn't have much characterization going for him apart from helping out Eclipsa and the heroes from time to time.
Cloud Kingdom of the Pony HeadsThe Cloud Kingdom is a sub-level kingdom of Mewni ruled by the Pony Heads, located in the skies of Mewni just below the edge of outer space. Unlike most of Mewni's kingdoms, which are matriarchal, the Cloud Kingdom is patriarchal, meaning that the throne could only be passed down from father to son. Unfortunately, all of King Pony Head's children are daughters...
- Big, Screwed-Up Family: The sisters are always fighting against Pony Head, attempting to usurp the throne with crazy, near sociopathic schemes, even intending to fake the murder of their sister (that they keep in a closet) to frame Pony Head and get her throne. Star admits that staying with them has been one of the most stressful situations of her life, even to her very intense life that included being killed by Toffee and reborn not that long ago, their father also seems eager to leave the house.
- Cute and Psycho: The sisters, even Pony Head. They are willing to go to great lengths to overtake the throne, including falsely accusing their sister of murder and vanishing Teta.
- Exotic Eye Designs: Some of them have pupils shape like stars or hearts.
- Flying Faces: The Cloud Kingdom are inhabited by floating pony and unicorn heads.
- A House Divided: While the sisters team up against Pony Head, it seems that they have a hard time staying teamed up.
- Massive Numbered Siblings: The royal family is made up of King Pony Head and his thirteen daughters.
- Succession Crisis: The Cloud Kingdom is patriarchal, and the throne of the Pony Head dynasty could only be held by sons. Unfortunately, despite King Pony Head's attempts, he managed to have thirteen daughters before he gave up and named his oldest daughter his heir.
- Unicorns: Many of them like the Pony Head family have horns on their heads. The only exceptions are Chezna and Hornanne.
- You Gotta Have Blue Hair: See individual entries for details.
King Pony Head's second-born child, a straight-laced and dependable warrior-in-the-making who shares Star's admiration for Mina Loveberry and doesn't get along with her older sister. Like at all.
- Fangirl: Of Mina Loveberry. When they were kids, Star and her used to argue over who would get to be her during their play fights.
- Hypercompetent Sidekick: As per tradition, she'll one day be the commander in chief of the Cloud Kingdom's Pony Head Army and is being groomed and trained to do so. Her entry in Star and Marco's Guide to Mastering Every Dimension has nothing but praise from Star.
- Sibling Rivalry: With Lilacia.
- Straight Man: To the rest of her siblings.
A total troublemaker with an ironic name. As her father has no expectations of her, she acts out unopposed in ways that put her eldest sister's shameful antics to shame.
- Fille Fatale: She always has a new boyfriend...or two...or three that she rides around on motorcycles on.
- Free-Range Children: Star describes her in Star and Marco's Guide to Mastering Every Dimension as "a runaway that comes home every morning."
- Ironic Name: Her name is Angel, and she's a worse brat than Lilacia.
- Royal Brat: She's even worse than Lilacia if you can believe it.
- Tempting Fate: Star thinks that her parents calling her "Angel" was just them asking for her to turn out as anything but.
The most vain member of the family. She spends most of her time looking at herself in the family reflecting pool and almost drowning when she falls asleep while looking at herself in the family reflecting pool.
- Exotic Eye Designs: She's the only one in the Pony Head family with heart-shaped pupils.
- Distracted by My Own Sexy: She spends most of her time looking at herself in a reflecting pool.
- Narcissist: Described as the most vain member of the family. Given that Lilacia is herself an unapologetic narcissist, that's saying something.Khrysthalle: Because of Ponyhead's attitude, I became terribly insecure, and now I have to compensate by putting all of my self-worth into my jaw-dropping beauty.
- Vanity Is Feminine: Female and the most vain member of the family.
As the fifth-born among her sisters, Jan-Jan is fated to be the kingdom's party ambassador. Which suits her just fine.
The middle child. Dull, nerdy, and largely unremarkable.
- Butt-Monkey: Constantly disrespected by all of her siblings, despite supporting them in their plotting against Lilacia.
- Middle Child Syndrome: In spite of being the sixth-born of the Pony Head Princesses, Shonda and Shinda came out as a pair, dooming her to this trope.
- Nerd Glasses: Wears a pair of these.
- Plain Jane: As a result of being the middle child.
There isn't a household in all the Cloud Kingdom that hasn't hosted tracks from the debut (and thankfully only) album of these royal twins. Because it's against the law if they don't. Shonda and Shinda aren't very good singers. Please don't tell their father. He'll probably try to get them to make more music in an attempt to prove you wrong.
- Creepy Twins: They give off a rather creepy vibe in "Ponymonium", peeking out from behind a couch and speaking at the same time in a Creepy Monotone. They have been even compared to the twins of The Shining even by the crew.
- Dreadful Musician: Described as such, with explicit comparisons to The Shaggs. We hear some of their music in "Ponymonium", and it's pretty bad.
The most unfortunately named member of the family. Hornanne's horn never blossomed, but this doesn't stop her from floating regardless or trying to make the best of her situation.
- Exotic Eye Designs: Averted. Unlike the rest of her family, she has normal pupils instead of star or heart-shaped ones.
- Foil: To Chezna, who willingly had her horn filed off.
- Ironic Name: Having "horn" in her name when her horn never blossomed.
- Tempting Fate: Her birth name, though it's much more tragic than what happened with Angel's.
- Yank the Dog's Chain: In Bam Ui Pati! she asks Seahorse if he can 3D-print her a horn like he did to Lilacia after she lost hers to Meteora. Pony Head chastises her for "always trying to be the center of attention."
Teta eats her dinner, she does her homework, and she never misses a day of school. She's a model Pony Head, possibly even a real contender for the Cloud Kingdom Crown if not for the fact that she isn't very...present.
- The Ace: She's the least troublesome of King Pony Head's children for reasons both valid and absurd.
- The Ghost: Played for laughs; she tends to not be around much.
- He Who Must Not Be Seen: When she does show up in person, her face is always at least partially obscured.
- Phrase Catcher: "Has anybody seen Teta?" is the most commonly asked question at her family's castle.
- How Do I Shot Web?: Star would love to take her up on her pony ride offers, but she's frightened with how poorly Chezna controls her legs. Keep in mind, Star's fine with mounting savage Warnicorns that try everything in their power to get her off of them.
- Meatgrinder Surgery: Whoever performed the operation couldn't even be bothered to file her horn all the way down or find a body that matched her coat.
King Pony Head's youngest daughter.
- Adorably Precocious Child: She's fairly bright and eloquent for her age, despite "not knowing all [her] numbers".
- An Axe to Grind: Threatens Star with one in "Ponymonium" to keep her and her sisters' plan a secret.
- Cute Is Evil: "Ponymonium" proves she can be just as messed-up and ruthless as her sisters, despite her young age.
- Enfant Terrible: She's no better than her sisters when it comes to usurping plans.
- He Knows Too Much: Once the Pony Head sisters start suspecting Star of ratting them out to Pony Head, Pranciss is willing to go straight for the kill.
Flying Princess Pony Head's father and the current ruler of the Cloud Kingdom.
- The Determinator: The Pony Head dynasty of the Cloud Kingdom is patrilineal with the role of King being passed down to the current monarch's firstborn son. King Pony Head helped produce a whopping total of 13 daughters before giving up and deciding to make Pony Head his successor.
- Dynamic Entry: Makes a pretty spectacular entrance to break up a fight between Star, Marco, his daughter, and the St. Olga's guards.
- Fire-Forged Friends: He and River became friends after the latter mistook him for a Greebeast (based on very flimsy evidence) and tried to wrestle him to death while they were teenagers.
- Hypocrite: Sends his daughter off to a Mind Rape reform school because she spends too much time partying, and then joins a party with King Butterfly (in someone's private property, no less) that nearly destroys the planet Earth.
- Lack of Empathy: In "Royal Pain", he announces that he's "ridiculously apathetic to the suffering of others," and that's why he's leaving the party.
- Large and in Charge: While his daughter is the size of a normal pony's head, he's larger than Star and Marco.
- Parental Favoritism: Sees Princess Pony Head as his most viable heir (mostly because her competition among her sisters isn't all that greatnote ) which is why he's so hard on her.
- Stage Dad: Even though they have zero actual musical talent, King Pony Head always wanted a twin daughter vocal group, so when his kids Shonda and Shinda got old enough he paid for them to produce a music album featuring the two singing duets. Predictably, the album didn't sell, but as the King of the Cloud Kingdom, he had the album "installed" in every household in his domain.
- Tough Love: He sends his daughter to St. Olga's Reform School For Wayward Princesses because he loves her and wants her to stop being such a troublemaker. While he was well aware that St. Ogla's was an unpleasant, prison-like school, it's unlikely he knew that brainwashing was involved.
- You Gotta Have Blue Hair: He has a blue mane.
Lucitor KingdomThe Lucitor Kingdom is a sub-level province located in The Underworld, and is inhabited mainly by demons. They became powerful allies of the Butterfly dynasty during the reign of Solaria the Monster Carver, when her older brother Jushtin brought them and the Pony Heads together in order to provide aid for the mewman-monster wars. Thanks to Jushtin's diplomatic skills, the Lucitor-Butterfly alliance still holds strong to this day.
The Lucitor Kingdom is ruled by its titular royal family, the Lucitors, consisting of Queen Wrathmelior, her husband King Dave, and their son Prince Tom.
- All Myths Are True: As "Naysaya" shows, they're responsible for Earth folklore involving demons, and apparently, they've been using the titular curse on humans for centuries.
- Amazing Technicolor Population: Demons are shown to be able to have skin colors like purple, dark red, blue, green, etc.
- Bigotry Exception: Much like the Pony Heads, the Lucitors get a pass in avoiding monster prejudice because they're wealthy royals. However, as Tom admits, it won't stop them from receiving dirty looks or rude comments.
- Big Red Devil: While some demons are indeed red, their general skin color and sizes vary. Queen Wrathmelior is a straighter example, being literally so big that mewman-sized buildings give her trouble.
- Cannot Keep a Secret: The Naysaya curse from the titular episode is an invoked example; whoever is afflicted will end up having their faults and deepest secrets revealed to the world. It'll go away once everything is revealed.
- Dark Is Not Evil: Mewni's underworld looks like hell, and it's populated by demons and souls, but other than that, the Lucitors' domain functions like any standard kingdom. Prince Tom was a subversion at first, but started playing this trope straight through Character Development.
- Fantastic Racism: As Tom admits in "Is Another Mystery", despite his family's royal status and wealth, they'll still be subject to the same racial prejudice that all monsters experience, because at the end of the day, demons still look like monsters.
- Foil: The Lucitors contrast Eclipsa's monster family. Eclipsa's a Mewman mother, while Dave is a Mewman father, with their larger monster spouses being of opposing genders. The Lucitors also got to keep their hybrid child, which had great importance in influencing how Tom developed as he grew up.
- Hell: Mewni's underworld looks like the stereotypical depiction, with dark, craggy environments; lava everywhere, ominous buildings, and souls being kept there. It's actually no less evil than any other kingdom in Mewni.
- Matriarchy: Implied; King Dave seems to have adopted his wife's surname upon marrying her, and Tom's surname is the same as his mother's.
- Our Demons Are Different: Demons appear in several episodes, with the most prominent being Tom Lucitor, the prince of The Underworld and Star's ex-boyfriend. They have their own kingdom in Mewni's Underworld and come in a variety of appearances, but typically seem to lean towards Dark Is Not Evil or Affably Evil.
- Really 700 Years Old: Demons are virtually immortal, as Tom's great-grandpa Relicor is still alive, and the way he said to Star and Marco "You don't live that long" more or less confirms this.
Tom's father who rules Mewni's Underworld with his wife, Queen Wrathmelior. While Mewman by blood, he fell in love with the Queen of the Underworld and moved there soon after.
- Aerith and Bob: His name is Dave and his wife's name is... Wrathmelior.
- Hair-Trigger Temper: He's part of where Tom gets his temper from, and it caused Tom no shortage of grief.
- Hot Skitty-on-Wailord Action: Unless the queen can shapeshift and change size, the mechanics of their coupling are best left to the imagination.
- Interspecies Romance: Dave is a mewman while his wife, Wrathmelior, is a demon. Together they had a half-monster son, Tom.
- Like Father, Like Son: Both he and his son Tom can have monstrous tempers. Tom really doesn't like the fact that he's similar to his father's temperamental side.
- Mister Big: King Lucitor is popularly known as "the Big Guy" for his ferocity, power, and influence, but in terms of actual height he's barely taller than River.
- Papa Wolf: In "Club Snubbed", Dave became angry at Star for "club snubbing" Tom, and his arguments with River disrupts the Silver Bell Ball until Tom and Star make up.
- Parents as People: Dave is loving and protective of Tom, but is seemingly oblivious to how his ferocious temper is influencing his son, or how Tom hates turning out like his old man in any way.
- Strong Family Resemblance: King Dave looks like Tom without the demonic features.
- Tiny Guy, Huge Girl: King Lucitor is barely taller than River, while Queen Lucitor is a Giant Woman. When standing together with his wife, her hand is almost as large as him.
- Vitriolic Best Buds: He has this relationship with River Butterfly. They go from playfully chatting with one another, to brawling and bickering over whose child snubbed who, to being buds again when Tom and Star make up.
Tom's far nicer, but positively enormous demonic mother who rules Mewni's Underworld with her husband, King Dave.
- Aerith and Bob: Her name is Wrathmelior and her husband's name is... Dave.
- Amazonian Beauty: Queen Lucitor is a muscular, strapping, statuesque demoness with a pink pixie haircut.
- Big Little Sister: "Lava House Fever" shows she has an older sister who is only about the size of a human.
- Big Red Devil: Queen Lucitor fits the part aside from being much larger than average and female. Tom's demonic features obviously came from her.
- Dark Is Not Evil: A huge and muscular demon, but also a Gentle Giant.
- Deathbringer the Adorable: She's a large and terrifying (yet attractive) red demon with an equally terrifying name, but she is the nicest and more patient of the Lucitors.
- Fisher King: When she's upset, it causes firestorms in the Underworld.
- Foil: Serves as one to Globgor, the father of Meteora/Mrs. Heinous. They're both massive, red-skinned, horned demon-like entities with multiple eyes, with weird names compared to their spouse and children's relatively more normal names, who fell in love with a Mewman and gave birth to a Mewman-Monster hybrid. Unlike Globgor, however, Wrathmelior not only managed to keep her child, but also gained a political ally in the Butterfly royal family.
- She also serves as a foil to John Roachley, Rhina the Riddled's husband and Celena the Shy's father. While they both fathered Mewman hybrids, John was such an abusive husband that Rhina had to use a heartbreak spell to try fix things, only to end up killing him, while Wrathmelior is a legitimately nice woman who won Dave's heart and had a loving relationship with him.
- Gentle Giant: Wrathmelior is a colossal-sized demon, but relatively well-mannered.
- Hair-Trigger Temper: While not as bad as her husband's, Wrathmelior does have some anger-issues. Her's can be worse than her husband's however in that unlike his, her's affect the weather in the Underworld, putting everyone, including Tom, in danger.
- Height Angst: She's so tall that she accidentally bumps into the Butterflies' ballroom chandelier, much to her annoyance. And she had to crouch while sitting down to watch the dances because otherwise she wouldn't fit in the seating area.
- Horned Humanoid: Like Tom, Queen Lucitor has gigantic horns that resemble those of a bull.
- Hot Skitty-on-Wailord Action: Unless she can shapeshift and change size, the mechanics of her and Dave's coupling are best left to the imagination.
- Interspecies Romance: Wrathmelior is a demon while her husband, Dave, is a mewman.
- Large and in Charge: Wrathmelior is likely the largest of her race, and thus, their ruler. Since she's the younger sister, it's possible that their kingdom chooses their rulers based on size rather than age.
- Little Black Dress: Queen Lucitor's outfit during the Silver Bell Ball is much more simple and saucier than those of the other queens in attendance.
- Mama Bear: It's revealed in "Lava House Fever" that Wrathmelior doesn't trust Star and doesn't approve of Tom's relationship with her due to Star and Tom's history. She does calm down eventually and gives Star and Tom her blessing.
- Modest Royalty: Played with; she wears a Little Black Dress and brings a tiny modern handbag with her to the Silver Bell Ball, while her husband and the most of the royals wear Requisite Royal Regalia. However, the simplicity of her outfit means she looks saucier and immodest compared to the other royals.
- Monochromatic Eyes: All three of her eyes are yellow, no pupils or irises.
- My Blood Runs Hot: Queen Lucitor cries tears of burning lava.
- Opposites Attract: The gentle Queen Lucitor is married to the hotheaded King Dave, although they turn out to be Not So Different because they both tend to lose their tempers. They just express it differently.
- Retcon: Between "Club Snubbed" and "Lake House Fever" her voices changed from incredibly deep to high-pitched.
- Shared Family Quirks: Like Tom, Wrathmelior releases heat uncontrollably when overcome by emotion.
- So Proud of You: If her applauding Tom's dance with Star and crying lava while doing it is of any indication.
- Supernatural Gold Eyes: Her eyes are entirely yellow, and she's a demon.
- Tears of Joy: In "Club Snubbed", she happily cries lava when she sees her son Tom reconciling with Star and doing a beautiful dance with flames and butterflies together.
- Third Eye: Queen Lucitor has a third eye on her forehead.
- Tiny Guy, Huge Girl: Much like the ruling Butterflies, but taken Up to Eleven; Queen Lucitor is ginormous compared to her Mewman husband, so much that she ends up bumping into the ballroom's chandelier. Even her hand is almost as big as her husband.
- Top-Heavy Guy: A rare female example. Her legs are very thin compared to her big and muscular upper body.
- The Unintelligible: She speaks in a demonic language that's only understood by other demons and her family.
- Vocal Dissonance: In "Lake House Fever", she has a high, squeaky voice.
- You Gotta Have Blue Hair: Tom gets his strawberry red locks from his mom.
- Your Size May Vary: She was several stories tall in "Club Snubbed", but seems to be less than fifteen in "Lake House Fever".
Tom's imp-looking, grumpy Great-Grandfather.
- Be Careful What You Wish For: He once used the Severing Stone to sever his love with his wife. Unfortunately, this resulted in him losing the memory of when he first fell in love, which he can never recover again. Millenia after this, he still regrets losing this memory.
- The Bluebeard: Tom jokingly refers to him as a lady killer. His awkward laugh afterwards heavily implies that the name is a literal one.
- Bookworm: Implied; he has a gigantic collection of occult books, and is quite knowledgeable with them, suggesting he is quite bookish.
- Chekhov's Gunman: First introduced in "Lake House Fever" as what appears to be a joke character, he comes back to play a more important role in "The Blood Moon Curse".
- Creepy Good: Even by his own family's standard, he is rather disturbing with his sharp teeth, crazy eyes, and shriek-like speech, completely creeping out Star the first time she meets him. However, he does prove rather helpful in his second appearance.
- Cool Old Guy: Creepy habits and grumpy temper aside, he's actually quite a cool guy, knowledgeable in the occult and helpful toward his great-grandson.
- Great Big Library of Everything: He owns a gigantic library that covers everything related to the occult.
- Grumpy Old Man: Implied; he is a Perpetual Frowner, constantly screaming, and easy to annoy.
- Hair-Trigger Temper: Apparently quite prone for outbursts of anger; his first appearance has him apparently get into a heated argument with his family over a scrabble game, and he is constantly seeching with exaggerated expressions (though admittedly, it's hard to say if the latter really is anger or if it's just how he speaks).
- Hellish Pupils: He has slit pupils.
- Jerk with a Heart of Gold: Grumpy, easily angered, constantly screeching and cheating at games, but when asked for help about finding the Severing Stone, he proves actually really helpful, actively guiding the group to it and warning them of the consequences.
- Meaningful Name: He's an extremely old man whose name is derived from "relic".
- Miniature Senior Citizens: He is about half of Marco's height, and several thousands of times older.
- Perpetual Frowner: Constantly seen with a seemingly unhappy expression, even while joining his family to play his favourite game.
- Posthumous Character: Subverted for comedy; he is first introduced in the series as an ominous painting on the wall, with Tom presenting as his great-grandfather to Star and saying he "was quite the ladykiller", seemingly implying he is long dead. As it turns out, the painting apparently is a door, and it opens to reveal a still well-alive Relicor standing behind it.
- Really 700 Years Old: He is several thousand years old at least.
- Running Gag: He tends to hide amongst objects that convey his likeness, and will pop out if anyone comes across the object he's hiding behind, or if he's in disguise as an effigy of himself.
- Technologically Blind Elders: Averted; despite being incredibly old, he was tech-savvy enough to install a computer in his library, allowing to quickly search any topic without needing to go through the physical books. Marco comments it's nice to have an old person who stays in touch with modern time.
- Ugly Guy, Hot Wife: Implied; we have yet to actually see his ex-wife aside from a painting of them together in his library, with a slash making her face unrecognizable. However Relicor himself is a small, creepy-looking, bald imp-like demon, and what we see of her body suggests she was at least tall and with nice curves.
- The Unintelligible: Communicates in screeches, not unlike his granddaughter, albeit much more high-speech. Other Demons do understand what he is saying, humans and Mewmen not so much.
- Winged Humanoid: Unlike the rest of his demon relatives, he has the appearance of an imp with bat wings on his back.
Tom's anger management coach.
- Ambiguously Human: Certainly seems so, but he's only ever seen in Tom's company (primarily around Tom's carriage) and he's never been outright stated to be human. Given Tom is prince of the Mewni underworld, he could very well be a Mewman.
- Hidden Depths: "Friendenemies" shows Brian can play the keytar.
- Late-Arrival Spoiler: His disguise as a white tiger is spoiled by the season 3 opening. That was a major twist in the episode it was in, since it showed Tom was doing everything as a test.
- Master of Disguise: Successfully impersonated a white tiger for almost an entire episode, with no slipups until he revealed himself.
- Morality Chain: Brian helps keep Tom's explosive anger under control.
- Nice Guy: Though he doesn't have a lot of lines, Brian is consistently seen as decent person.
- Satellite Character: Only ever seen around Tom, and only in plots where Tom controlling his anger is a plot point.
- Skewed Priorities: Brian is perfectly alright with letting Tom lie, scheme, and be generally evil so long as he keeps his anger in check. This could be written off as considering he's coaching the prince of the underworld, he'll take what he can get in terms of progress.
- Tame His Anger: His job is to help Tom with this.
Pigeon KingdomOne of the kingdoms of Mewni, inhabited by sapient pigeons. Despite looking like dumb, mindless birds, they are actually very ruthless and aggressive. They disdain anyone learning the language of humans, preferring to use pigeonspeak instead.
They are ruled by the royal Pigeon family. Their son, Rich Pigeon, becomes a friend of Star and her entourage.
- Animal Stereotypes: They are intelligent pigeons, but they don't look very bright at first, are very aggressive and their poop is visible in all the places of their castle.
- Artificial Limbs: They occasionally equip artificial legs to interact with Mewmen and other kingdoms.
- Feathered Fiend: They can be very aggressive if their royalty is in danger.
- Furry Confusion: Mewni has a variety of birds, but the pigeons, while looking like ordinary birds, are actually sapient (with Prince Rich Pigeon being able to speak the Mewni toungue). That being said, they don't get enough respect by Mewmans because they're often treated like all other birds.
- Killer Rabbit: They look and act like ordinary pigeons, but it's revealed that the Piegeons got their own kingdom after taking over the castle of another kingdom, and said castle is full of skeletons...
- Nouveau Riche: Their Pidgeon Kingdom is described as being relatively recent compared to the others, but already very wealthy.
- Obfuscating Stupidity: According to Rich Pigeon, they have been pretending to be mindless birds for a long time.
- Screw the Rules, I Have Money!: While not exactly monstrous-looking, they still are sapient birds who equip robotic human legs, which would usually be enough to make them suffer the usual Fantastic Racism, and unlike the Lucitor Kingdom and the Ponyheads, they do not benefit from multiple generations of alliance with Mewni due to their Kingdom being brand new by comparison. They still escape being cathegorized as monsters by Mewmen and get to be treated as allies because of their wealth.
- Synchronized Swarming: They form one single mass to attack and don't break formation.
- Zerg Rush: Their main method of attack. They can break walls by sheer force of numbers.
The rulers of the Pigeon Kingdom.
The prince of the Pigeon Kingdom.
- Badass Baritone: When he actually speaks, he does so in a deep voice. Pony Head even calls it a "strong handsome man voice".
- His Name Really Is "Barkeep": Called "Rich Pigeon", which sounds like a description, but this turns out to be short for "Richard Pigeon".
- Humongous Mecha: Has a pair of giant robotic legs in his collection.
- Nice Hat: He wears a purple hat with a light blue feather on it.
- Punny Name: It turns out "Rich" is short for Richard.
- Reasonable Authority Figure: He agrees with Star's idea of ending monster discrimination. He even gives an speech to his people to convince them to free Star and her friends. He also finds his people's tradition of refusing to learn the Mewman language and passing themselves off as stupid birds to be ridiculous.
- Rousing Speech: Gives one to the kingdom, rallying them to join Star's cause for justice.
- Screw the Rules, I Have Money!: He is a pigeon with legs (though they aren't actually his real legs as Star later finds) and he is neither mewman nor humanoid, but acording to Queen Moon, he is over monster discrimination because he's rich.
- Screw the Rules, I'm Doing What's Right!: As per his speech, he broke the law by learning Mewni's language, but did it for the kingdom's future.
- Suddenly Voiced: He is the only pigeon that is able to talk in Mewni language.
- Toothy Bird: He displays fangs when angry.
- You Can Talk?: The fact he speaks Mewni language was a huge reveal to the heroes and the audience.
- Artificial Limbs: He has two huge arms that he can take off and store in a suitcase.
- An Axe to Grind: He holds an axe way bigger than him, though he only uses it to stand at the level of Marco's forehead.
- Death of a Thousand Cuts: According to Pony Head, his method of execution is called "death by a thousand pecks".
- There Was a Door: Even when there is a door in the room where Star, Marco and Pony Head are imprisoned, he breaks a hole in a wall bigger than him.
Johansen KingdomA kingdom inhabited by boisterous barbarians. While the Butterfly family focuses on magic and cunning, the Johansens focus on brute strength. Despite becoming in-laws through the marriage of King River Johansen and Queen Moon Butterfly, they're not very well-received by Moon's uptight and posh relatives, who look down on their loud and brutish ways.
- Badass Beard: King Johansen has a thick, curly beard. His son River got one, too, when he got older.
- Commonality Connection: Invoked by River in "Game of Flags", who brings up the titular flag game to stop the squabbling between the Butterflys and Johansens.
- Cuddle Bug: Most of them are not afraid to get physical with each other. Both River and Star inherited this traight
- Jabba Table Manners: In "Game of Flags", the Johansens eat their corn rather messily during a family picnic, much to the Butterflys' great disgust.
- Not So Different: As shown in "Game of Flags", the Butterflys can be as violent and ruthless as their barbaric in-laws, despite their great disdain for them, though the former prefer to do theirs with style.
- Obnoxious In-Laws: Through Moon and River's marriage, the Butterflys and Johansens are in-laws. The Butterfly family sees the Johansens as loud, uncultured brutes, while the Johansens in turn see the Butterflys as obnoxiously uptight and well-mannered.
- Slobs vs. Snobs: The Johansens represent the slobbish side of the Johansen-Butterfly family; they're loud, they dress in fur rather than posh clothing, they have Jabba Table Manners, they're uncultured, etc. The Butterfly family hates them for spoiling "the Butterfly family tree" and can't understand why Moon married a Johansen.
- Super Strength: The Johansen family focuses on this to counter the Butterfly family's affinity for magic. This is where River gets his own strength from.
- Trademark Favorite Food: Like the Butterflys, it's corn. River loves it, too.
Star's cousin on her father's side.
- Hipster: He is a fan of distressed clothing and complements a monster on his ripped jeans.
- Jerk with a Heart of Gold: While he comes off as a stereotypical spoiled brat, Rock was also the first person to break the tension by befriending a monster at Star's party.
- Phoneaholic Teenager: He barely looks up from his cell phone at the Silver Bell Ball.
- Major Injury Underreaction: The horns on his shoulders were actually embedded there by a freak boating accident. He apparently never bothered to have them removed.
The princess of a forest kingdom allied with Mewni.
- Because You Were Nice to Me: She makes fast friends with Slime because he's apparently the first person to show concern that her swollen spider bite is causing her discomfort, instead of just assuming she's just supposed to have it.
- Dating What Daddy Hates: Beautifully subverted. Turns out Penelope's parents are more than accepting of her dating Slime Monster.
- Interspecies Romance: By season 4, she (a Mewman) is in a relationship with Slime (a monster).
- Jungle Princess: She is the heir to a forest kingdom and she even wears leaf-patterned dresses and a wooden crown.
- Mixed Ancestry: She is an interracial princess given that her father is Caucasian and her mother is Ambiguously Brown.
- Phoneaholic Teenager: She's glued to her phone compact throughout the whole time she and her family are visiting Eclipsa in the monster temple. Turns out she was keeping contact with her boyfriend Slime as he wanted to come too.
- Sugar-and-Ice Personality: She is very rude and insulting towards Slime but opens up after he heals her spider bite, and by Season 4 it's pure sugar as the two of them are dating.
- Unwitting Instigator of Doom: After being ambushed by Mina, she returns to the party without Slime which sparks bitter tension between the monster and Mewman youth over what happened to them.
The prince of the waterfolk.
- Fish Person: He is somewhere between this an a merperson as he is fully covered by scales but his features are very humanoid.
- He Is All Grown Up: Pony Head's comments imply that he has recently gone through a growth spurt.
- Interspecies Friendship: Appears to be good friends with Tom. Also counts as an Odd Friendship due to them coming from extremely contrasting kingdoms.
- One Steve Limit: Shares his name with the title ghost character of "Hungry Larry".
- Our Mermaids Are Different: Interestingly he has a bipedal lower body while the king and queen have octopus tentacles and a fish tail respectively. The Magic Book of Spells also shows one of his relatives to have a fish tail.
The princess of the Jaggy Mountains and a former student at St. Olga's.
- Alliterative Name: Jaggs Jaggy.
- All Women Are Lustful: She seems very...excited at the revelation that Princess Marco is actually a boy.
- Big Ol' Eyebrows: Her eyebrows are quite thick.
- Cute Monster Girl: Jaggs has various monster features and can be seen as pretty adorable.
- Delinquent Hair: She has a green mohawk and contributed to turning the strict and uptight St. Olga's into a teenage paradise.
- Graceful Ladies Like Purple: Her main dress is blue violet and she has purple lipstick.
- Tomboyish Voice: She has a very low and gravelly voice.
- You Gotta Have Blue Hair: She has jade green hair with streaks of yellow.
Eclipsa's ex-husband of the Spiderbite Royal Family and the king of Mewni 300 years ago.
- Awful Wedded Life: Eclipsa's disgusted reaction at his hologram implies their marriage was not a happy one. The Magic Book of Spells elaborates that it was a Marriage of Convenience from the start, meant to give Shastacan a higher title and Eclipsa (following her late mother's will) stronger ties to the Spiderbites. Things turned worse when Shastacan gained a very one-sided attraction to Eclipsa, and even suggested they have children, after which Eclipsa eloped with Globgor.
- Beauty Mark: A mark on the lower right side of his cheek.
- Even Evil Has Standards: It's important to point that despite his contempt towards Meteora, Shastacan took the trouble to find a Parental Substitute for her instead of just dumping her or killing her, implying that maybe the death of a baby wasn't a thing he wanted to carry on his conscience.
- Even Evil Has Loved Ones: The Magic Book of Spells suggests that he did have genuine feelings for Eclipsa at one point. Unfortunately, those feelings utterly vanished after Eclipsa abandoned him in favor of Globgor.
- Fantastic Racism: Absolutely refused to acknowledge Meteora as his heir after Eclipsa was crystallized because she was part monster.
- Foil: To Globgor. Both were the husbands of Eclipsa, but Globgor was her childhood friend and second husband while Shastacan was betrothed to Eclipsa. Shastacan was shorter than Eclipsa, while Globgor is absolutely enormous. The Mewman king always had a serious expression on his face while Globgor had a noticeable smile (which caught Eclipsa's attention). Shastacan is dressed in a blue and white royal garb, whereas Globgor is a red-skinned shirtless monster wearing only a black speedo for an outfit. Shastacan abhorred Meteora and considered her heinous, while Globgor loved his daughter, and was crystallized while probably fighting to protect her and Eclipsa. Also, while Eclipsa had an Awful Wedded Life with Shastacan but she was Happily Married to Globgor.
- Hate Sink: His hatred of monsters and his willingness to throw away his step-daughter and replace her with a peasant girl because he would rather not have a half-monster heir to the throne shows just what kind of King he was. Also, his design just screams "douchebag".
- Jerkass: He doesn't seem to have been a very pleasant guy considering Eclipsa's disgusted reaction when seeing his image again on her trial and the fact that he replaced the rightful heiress to the throne with a peasant child just because she was a half-monster hybrid.
- Karmic Death: Shastacan had Meteora stripped of her rightful place as princess and shipped off to a horrible childhood. Meteora's father Globgor ate Shastacan afterward.
- Posthumous Character: He was already a middle-aged man at the beginning of his ex-wife's 300-year imprisonment. Globgor ate him.
- Predecessor Villain: His villainous actions in the past are the cause of Meteora's actions in the present.
- Psycho Ex-Boyfriend: When his wife Eclipsa ran away with a monster and gave birth to Meteora, he treated Meteora as a bastard child of a monster and Mewman and denied her the throne by replacing her with a peasant daughter. He only saw her as an abomination and as a mark of shame and corruption on a pure Mewman society and marriage.
- Small Role, Big Impact: He's long dead and has only appeared in a couple of very short flashbacks, but his actions shaped the entire subsequent history of Mewni and are at the root of the main conflict of Season 3.
- Wicked Stepfather: Par excellence. It may have only been a dramatization rather than a showing of what literally happened, but seeing him literally throw his stepdaughter away spells things out pretty clearly.
- Woman Scorned: A very rare male example. He abandoned and replaced Meteora because she was both a hybrid and an offspring of an affair between his wife Eclipsa and a monster. Whom she ran away and eloped with. He was also the one who ordered their capture and crystallization.
Pie IslandA notorious den of liars, thieves, slavers, and bakers. They are also the people whom Festivia Butterfly hails from.
- Always Chaotic Evil: To date, the only Pie Folks shown to be decent people in the show either live away from the island and disown their origins entirely (Foolduke), or were raised entirely away from the island with completely different beliefs (the second Butterfly dynasty). All other individuals are portrayed as unscrupulous criminals of all sort, and if one tries to insist that My Species Doth Protest Too Much, it's likely that he is trying to trick you into a con.
- Trademark Favorite Food: Pies, obviously.
- Wretched Hive: Pie Island basically is portrayed as your stereotypical pirate town; filled with all kinds of thieves, slavers and mongrels looking for ways to con you out of your money or trick you into becoming slaves.
The leader of the Pie Folk.
- Blatant Lies: He tells Moon that she is free to choose whether to stay with him or leave. But when she chooses to leave, he orders his underlings to stop her.
- Con Man: Introduced playing a Long Con where he pretends to save Star, Marco, and River from another con artist to convince them to get into his wagon, which transforms into stocks so he can trap and sell them.
- False Friend: Convinces an amnesiac Moon to bake pies for him to sell by pretending to be her friend.
- Hook Hand: Or a gavel for when he's auctioning off slaves.
- Large Ham: Spends most of his time onscreen chewing the scenery, complete with a pie crust depicting Festivia's history.
- Master of Disguise: Wears a disguise of a baby-faced man that somehow involves him folding his body in half.
- Pirate Pegleg: Replaced with a spatula, of all things.
The living embodiment of the Magic Instruction Book for Star's magic wand, and Star's guide in magical matters.
- Abusive Parent: To the original Magic High Commission. He's neglectful, dreads having to do anything with them, and, in his few onscreen interactions with them, seems fairly quick to belittle them. However, the two who get the worst treatment are Rhombulus and Reynaldo, who together seem to share the position of The Unfavorite.
- From what we see, he regularly talks down and belittles Rhombulus, who considers him to be the "biggest jerk in the universe". He also turned Rhombulus' hands into snakes to teach him "that having snakes for hands is not easy" (meaning, essentially For the Lulz) and apparently never thanked him for giving him the crystal in his forehead.
- His treatment of Reynaldo crosses straight into Kick the Dog territory. He's undeservedly dismissive to the poor guy and seems to hate being around him the most of all, despite the fact that one of the main reasons for his disdain towards him, Reynaldo only speaking through rhymes and riddles, is due to a curse by Rhina the Riddled and not his fault in way, which Glossaryck knows. It's even more egregious due the fact that Reynaldo is the only one of his siblings who doesn't flat-out hate him and actually wants to have a regular father-son bond with him.Reynaldo: Through darkness, slumbers, toils, solemnly alone. No game of catch, no father, no home.
Glossaryck: [enters from behind] Hey, Reynaldo?
Reynaldo: [visibly brightens up] Father!
Glossaryck: Yeah. Can we just go forward in time a bit? Thanks.
Reynaldo: Thou makest haste like wind, we shall arrive and-
Glossaryck: Oh, geez, just go. Just go!
- Achilles' Heel: His existence is bound to the Spellbook, meaning that destroying it will also kill Glossaryck. And despite the book being a very powerful magical artifact on its own, it's still vulnerable to things as mundane as getting thrown on a bonfire like any normal book would be. That being said, Glossaryck can still be brought Back from the Dead after this. Destroying all of magic, on the other hand, kills him permanently.
- Almighty Janitor: He's subservient to whoever owns his book. He's also said to be an omnipotent, omniscient, Overdeity-level magic user above the likes of the Physical Gods in the Magic High Commission.
- Amazing Technicolor Population: He has dark blue skin.
- Ambiguous Situation: He apparently dies when Ludo burns the book of spells, but he is able to pop in for a conversation with Star after Toffee shatters the wand fragment with her still inside. It's hard to tell whether he was Killed Off for Real and Star was able to talk to him because she was near death herself, or if he was still alive and he used his Reality Warper powers to teleport inside the wand fragment for that conversation, or if he got scattered across dimensions. He later returns after Star drops a fragment of the Book of Spells into the Citadel of Magic, having been explicitly revived from the dead, so for all intents and purposes, Ludo burning the book killed him.
- Ascended Extra: He only had two speaking appearances and a handful of cameos in season one. In season two, he has more of a recurring role.
- Astral Projection: Since he was unable to go anywhere without the book, he can project his consciousness to other locations without physically leaving. When he does, it's a Hard Light construct of himself who can be still be touched and retains his powers even outside his physical form.
- Back from the Dead: After he is burned up along with the Book of Spells, he is brought back to life when Star drops a fragment of the book into the Citadel of Magic. According to The Magic Book of Spells, he has been reborn at least four times. However, it is implied that the destruction of all magic in the series finale kills him permanently.
- Badass Beard: He sports a nifty-looking beard.
- Badass Teacher: The instructor of all of Mewni's future queens and is one of the most powerful beings in the galaxy.
- Be Careful What You Wish For:
- His ideal pupil is someone who doesn't question his teachings (like every Queen of Mewni sans Eclipsa) and someone who doesn't require him to jump through so many obtuse hoops to trick them into wanting to learn like Star. Ludo fits both of these criteria, but after a very brief honeymoon with this change of pace, Glossaryck becomes disillusioned with his complete lack of imagination, his blind adherence to instruction, and his increasingly sad and creepy attempts to turn him into a surrogate father figure.
- Glossaryck absolutely loves to Troll, manipulate, and bully his students, behavior to which the gullible and insecure Ludo is an ideal victim. Unfortunately, after being raised by his Abusive Parents and usurped by Toffee, Ludo reacts very badly to Glossaryck's Jerkass God behavior, and unlike the Princesses of Mewni he's not trained, obligated or duty-bound to put up with it. Once Glossaryck makes one too many jokes at his expense, Ludo flies into a fit of rage and murders him.
- Because You Were Nice to Me: Downplayed. It's been noted several times that Glossaryck has no side, good or evil, and serves anyone who possesses the Magic Spell Book. That being said, he's also admitted Eclipsa was his favorite Queen of Mewni because she never questioned his teachings.
- Berserk Button: Downplayed. He gets irritated and tired when the Queen of Mewni steps in and tells him how to do his job. Not because he's high and mighty about it, but because he has that talk with every queen (save for Eclipsa).
- Beware the Silly Ones: He's a Small, Annoying Creature, but don't attack him directly; he'll be untouchable.
- Black Bug Room: The comicbook mini-series reveals that his Dissonant Serenity is due to his usage of one, mentally playing out his emotions through a hokey Dom Com scenario and its cast (who all greatly resemble him in appearance and name).
- Blunt "Yes": Comes up a couple times in "The Hard Way" with Ludo.
- In the opening...Ludo: You will not resist. Resistance is pointless!
Glossaryck: Uh, you mind hopping off [the book]? Thank you. Okay, let's get started.
Ludo: What? You're not going to resist? Even a little resistance?
Glossaryck: Look, it's your book now, I'm just here to help you. Or not. Up to you.
Ludo: Really? You want to teach me?
Glossaryck: Oh, yes. Sure.
Ludo: What's your game? You must want something.
Glossaryck: Oh, I don't have wants. I have a job.
- And at the end:
- In the opening...
- Bystander Syndrome: If a situation is not magic related, he'll say it's not his problem.
- Came Back Wrong: By "Rest In Pudding", Glossaryk is brought back to the physical plane from Sanctuary, but his mind isn't all together. This ends up being a subversion, because "Conquer" reveals he was just Obfuscating Stupidity trying to warn everyone about Eclipsa's monster lover, Globgor.
- Casual Danger Dialog: He is often summoned in dangerous circumstances, but tends to maintain a very casual attitude. This is justified because he is immortal and generally knows how circumstances are going to turn out. In "Into the Wand", he defies this trope and he maintains a grave, cautious tone, because the wand's magic is very unpredictable and while he is immortal, he is not invulnerable, as he nearly gets ensnared by the wand's magic when he and Star get separated.
- The Chooser of The One: Parodied. When he comes across the amnesiac original Mewmans, he forms the original wand using Meteora's raddle and a baby unicorn, then proceeds to choose its wielder with a game of eeny-meeny-miny-moe, moe becoming the first queen of Mewni and being given the wand.
- Cloudcuckoolander: Even by this show's standards, he's completely insane.
- Cool Teacher: He adjusts his teaching style to help whoever owns the book reach their full potential. He was straightforward to the no-nonsense Queen Moon, a Trickster Mentor to the chaotic Star, and uses positive reinforcement for the self-loathing Ludo. With Meteora he plays off of her empathy and willingly put himself in danger to teach her how to dip down.
- Cryptic Conversation: Plays out his lessons in metaphors or riddles. Whenever somebody's confused by them, his voice goes flat and he barks out a variant of Figure It Out Yourself.Star: Anyway, Glossaryck didn't give me any instructions, so...
Queen Moon: Hah, that sounds familiar.
- In a later episode, Moon questions his sudden use of this trope, stating that he'd always been very direct when training her. Based on Glossaryck's answer, it's likely he teaches differently for every princess, but usually defaults to being unhelpful otherwise.
- "Conquer" reveals he's been doing a season-long case of this — "Glob-gor!" refers to Globgor, Eclipsa's monster husband whom she runs off to join by the end. Suffice to say, his warning didn't land until it was too late.
- Even when he says things that seem completely straightforward, he often includes statements that actually mean something other than the obvious. For example when giving Moon a "The Reason You Suck" Speech about her interference with his teaching of Star, he mentions that the only queen who never once interfered with his teaching methods was Eclipsa. It turns out that this is because he never taught Eclipsa's daughter, and she was already frozen in crystal when taught the next queen, Festivia. He also simply lied in that speech, by saying that Eclipsa was "(Moon's) great-great-great-great-great-great-great-great grandmother" when in fact Moon isn't actually related to her at all.
- Death Is Cheap: As shown in the The Magic Book of Spells, his bucket list includes "die and be reborn", checked four times.
- Drama-Preserving Handicap: Glossaryck being bound to the spellbook helps prevent his vast magical prowess from becoming a Story-Breaker Power. Even during periods when he exists without the spellbook, he almost never directly involves himself in the conflicts that the protagonists get caught up in.
- Early-Bird Cameo: He first appears in "Star Comes to Earth", watching with King and Queen Butterfly as Star bungles through her first day with the magic wand. He also had a blink-and-you'll-miss-it cameo in "Monster Arm" when Star is rapidly flipping through the manual before being properly introduced in "Mewberty".
- Eccentric Mentor: His advice is useful, but tends to be incredibly vague, and his demeanor is rather off-putting. "Page Turner" reveals this is an act that Glossaryck puts on to deliberately challenge Star, as Star learns best through action rather than instruction.
- Elderly Immortal: He's been teaching the Butterfly family magic as long as they've had the wand.Glossaryck: I'm not tall enough to go on any ride, but I've been on them all.
- Empty Shell: Whatever Star did at the sanctuary restored Glossaryck's body but not his mind, causing him to act like a dog because of his complete lack of memories. This turns out to just be a case of Obfuscating Stupidity where "Conquer" reveals he was just trying to warn everyone about Globgor, who is Eclipsa's monster lover.
- Everyone Has Standards:
- He may be a jerkass neutral but he hated working with Solaria. He barely helped her with her magic due to her war with the monsters, saying that he doesn't get involved with politics. Solaria also states that she keeps her notes on the "Total Annihilation Spell" a secret from Glossaryk.
- He apparently couldn't stand Crescenta the Eager because she was so obnoxious, making a point to mention he preferred her sister Dirhhennia.
- Extra Digits: His hands sport six spindly fingers. In a world where Four-Fingered Hands is otherwise the norm, this stands out. Strangely, he still has only four toes on his feet.
- Face Death with Dignity:
- While his death is left ambiguous, Glossaryck kept calm as the magical spellbook was burned, thus killing him in the process. He even admitted to knowing that it was coming.
- Later, in the finale, when magic starts disappearing, he remains calm, knowing that he'll die soon, and stays in the Realm of Magic as it collapses, saying that a good captain always goes down with his ship.
- Fantastic Light Source: His head gem can function as a flashlight.
- Food as Bribe: He will only serve magic princesses or people who spoon-feed him pudding.
- The Friend Nobody Likes: Marco was never all that fond of him, Rhombulus thinks he's the biggest jerk in the universe and King River was happy he was gone after Ludo stole the book. There's a chance that Glossaryck doesn't even consider Star his friend, which caused Star to stop considering him as her friend. When Ludo brings up that Glossaryck tends to come and go as he pleases, the Magic High Commission (who it must be mentioned have been around and known Glossaryck for the entirety of their potentially eons long existence) admit to this, implying that Glossaryck may have never been very close to anyone. Taken a step further in "Rest In Pudding" where the Magic High Commission are shown holding a funeral for Lehkmet but no funeral is mentioned for Glossaryck, implying that his death was not mourned by his coworkers.
- Gambit Roulette: His plan in "By the Book". Subverted though, as based on his nonsensical explanation, he may or may not have actually planned everything from the start. He does however, appear to possess unexplained knowledge of several other things, such as the location, contents, and emotional importance of Star's diary in "My New Wand".Glossaryck: Oh you didn't hurt my feelings. I have no feelings. It was all part of the plan.
Star: What do you mean, "part of the plan?"
Marco: Yeah, why'd you lock yourself in the doughnut box, then?
Glossaryck: I went into that box on purpose because I needed to get to that candy.
Marco: Ohhh. Wait, what?
Glossaryck: Well, how would you rocket yourself from a trash compactor?
Marco: What? I don't know—
Glossaryck: Marco, Marco, I had to be in that doughnut box, so I could land in Ludo's way, so I could trip him up and save the day.
Marco: Wait, wait, so you're saying that you did all that on—
Glossaryck: Boom-nuggets! (laughs)
Marco: (grunts) Fine.
- Good Counterpart: To Miss Heinous. Unlike Ms. Heinous' school which exists to brainwash princesses into being fitting a single "ideal" mold, Glossaryck teaches his students discipline and how to meet their potential without trying to control them. It's why he gets angry whenever one of his former students try to control the lesson plans of the next generation, as he sees it as infringing on the development of his latest student and stifling the qualities that make them special.
- Heroic Comedic Sociopath: As the above quote reveals, it is possible he acted hurt and hid in a doughnut box throughout the entirety of "By the Book" for absolutely no reason at all. He even outright states in that conversation that he "has no feelings". Though "Into The Wand" reveals even this is a lie as he is visibly afraid of entering the wand and later comforts Star when she feels inadequate. He's also not entirely selfish, as he commends Star on her decision to destroy magic to stop Mina Loveberry despite knowing it will kill him.
- Heroic Sacrifice: Indirectly. He commends Star on her decision to destroy magic and stays in the realm of magic while it collapses.
- Jerkass God: He's a powerful Physical God, but he's also considered quite unlikable to a number of people. Plus, he has his share of some nasty Kick the Dog moments.
- Jerkass Has a Point: As annoying as he can be, Glossaryck had every right to be annoyed with being questioned about his teaching methods.
- Jerk with a Heart of Gold: Heavily downplayed. One of the sole things people can agree about him is how much of a jerk he is, but while he denies it, he does actually have feelings, and cares for several people including Star, Marco, Moon, Eclipsa, and Meteora.
- The Jester: While not an official jester, he has the constructive troll qualities of one. Glossaryck's loyalty only lies with the book and whoever owns the book, owns Glossaryck. Glossaryck is usually evasive and enigmatic with his teachings and often modifies his methods with each owner. He can be nice to the likes of Eclipsa and Meteora but he's usually indifferent to the politics of Mewni, often responding with backhanded comments and a candid viewpoint.
- Killed Off for Real: He, along with the Magic High Commission, dies when magic disappears in The Realm of Magic.
- King of All Cosmos: Glossaryck is a being almost as old as the universe himself, knowledge so powerful, but he is very eccentric.
- Kryptonite Factor: The wand seems to be the only magical force strong enough to pose a threat to him, and that's only when he was inside of it.
- Large Ham: "SCRRRAAAAAAPE THE SIIIIDES!!!"
- Leitmotif: His appearance is often accompanied by sitar strings.
- Literal-Minded: He responds to Ludo's request for "hard training" by giving him a bunch of pointless physical tasks.
- Loyal to the Position: Glossaryck's main concern is fulfilling his duties and serving the one that owns the Book of Spells, even if he doesn't like them or they're evil.
- Manipulative Bastard: It's heavily implied that he has been manipulating the events of history to get the Butterflies to destroy magic (despite giving it to them in the first place); just look how he instructed an infant Meteora to dip down, which came in handy for her to get her Butterfly form and help the adults. He even manipulates a young Toffee into hating magic so much to renounce the chance for peace so he could be Star's proof that destroying magic is indeed possible.
- My Master, Right or Wrong: Has served a majority of Mewni's queens, from the heroic to the traitorous. In "Bon Bon the Birthday Clown", when Ludo captures the spell book, he grudgingly pledges loyalty to the villain. However, he will cater to them on his terms. Since his existence is bound to the book, it means he can't leave even if he wanted to. After the book is burned and he is subsequently revived however, this is averted. He's free to do as he pleases and doesn't have to obey anyone, but will help someone if he wants too.
- No-Sell: He's the only being shown to be able to break free of being completely encased in Rhombulus's crystals. He can also instantly undo the petrification effect of Yada-Yada berries on himself.
- Not So Stoic: In "Moon the Undaunted" he is seen openly sobbing over the death of Moon's mother. He even mentions that he "really liked her".
- Obfuscating Stupidity: Throughout season 3 he pretends to be an animalistic child who can only say "Glob-gor". In actuality, his sentience was fully restored and he was trying to tell Star and Marco about Eclipsa's lover, Globgor. He drops the act in the finale.
- Offscreen Reality Warp: Mostly to summon multiple hands.
- Omniscient Morality License: His advice is so accurate in retrospect, it's amazing that he just can't flat-out see the future. But even on magic-related incidents, he's Brilliant, but Lazy.Star: Oh my gosh, I am so sorry Glossaryck. Of course you're our friend.
Marco: Uhh... Is he though? All this guy has ever done for us is hand out weird riddles and eat pudding.
- One-Word Vocabulary: After being brought Back from the Dead, the only thing he is able to say is "Glob-gor". Or rather, it's the only thing he says in an attempt to tell everyone about what (read: who) Eclipsa wants.
- Only Mostly Dead: Ludo burns the book in a fit of rage and Glossaryck burns up with it, but he shows up again after Star is trapped in Ludo's wand fragment and the crystal is shattered by Toffee, the two in some kind of purgatory. He is fully brought Back from the Dead after Star drops a fragment of the spellbook into the Citadel of Magic.
- Ooh, Me Accent's Slipping: His vaguely Indian accent slips at times, particularly when he is describing nature as a garbage truck to Marco in "Mewberty". However, he totally drops the accent in later appearances.
- Out of Focus: Despite his increased screen time in Season 2, Glossaryck more or less becomes irrelevant to the plot in Season 3 after coming back from the dead in "Rest in Pudding." This is then subverted in Season 4, where he isn't as important as in Season 2, but has a bigger hand in the plot and appears more often even when not plot-important.
- Parental Neglect: On the giving end. Glossaryck is the creator of the initial five members of the Magic High Commission, making him for all intents and purposes their father, and he doesn't like any of them one bit, dreading having to deal with any of them at any point. With Hekapoo, Omnitraxus, and Rhombulus, the animosity is mutual, and while Lekmet's feelings on him are unknown, Reynaldo is the one hurt the most by it, being a "Well Done, Son!" Guy also looking to go back to the Magic High Commission, with Glossaryck dreading dealing with him the most.Glossaryck: Here's a free extra lesson for ya, don't have children.
- Physical God: He is an omniscient being of magic unmatched by any, and only obeys others due to being bound to the book. For perspective, the Magic High Commission, some of the strongest magical beings in the universe, are all his children, and can't hold a candle to him.
- Power Crystal: The one on his forehead can be used as a flashlight and to summon various magical constructs. Notably, he refuses to remove it when he needs to pass through a magical Metal Detector Checkpoint. "Crystal Clear" reveals that it was a gift from Rhombulus, though it's also stated that even without it, he's extraordinarily powerful. It also calms him down if you rub it, as demonstrated by Queen Eclipsa.
- Punny Name: On "glossary", since he lives in a magic tome.
- Rage Breaking Point: In "Page Turner" he lifts the ground floor of the Magical Council's headquarters and smashes it into the the top floor after being told that the radio, the elevator, and even the stairs are on the fritz.
- So Proud of You: He told Star this when she removes magic from the Realm, because he knew she's doing the right thing.
- Stable Time Loop: He's heavily implied to be the creator of one. In "Meteora's Lesson", he and the infant Meteora go too far back in time and meet what are implied to be the first Mewman's, all covered in the goo from the Magic Dimension and left amnesciac. He then proceeds to inform them of who they are using the picture book depicting Mewni's founding, gives them Meteora's raddle with a baby Unicorn creating the first wand, and tells them to huddle against a stump before a storm occurs which created Stump Day. Meaning, the entire reason Mewni exists is because of Glossaryck, and the only reason he could make it exist is because it already did.
- Stepford Smiler: It's possible that he doesn't care about Star or any of the people he teaches. Much like a school teacher, he just acts close and friendly to his students to better teach them, but it's ultimately just a job to him and Star is just one of many charges he's had over the years.
- Suicide by Cop: He incited Toffee's plan to destroy magic by going back in time and making him resent magic. When Toffee fails, he nudges Star into doing it instead to stop Mina and her Solarian warriors. Since he is inextricably tied to magic this leads to his own death. He even congratulates Star for doing so.
- Time Abyss: If his appearance in the tapestries of Mewni's previous queens is anything to go by, he's thousands of years old. His statement that Eclipsa, who existed at least a few hundred years ago, was the only queen who didn't question his teachings further supports this. He also created the Magic High Commission, who are all implied to be thousands of years old, if not more. In The Magic Book of Spells, Glossaryck says "I've existed forever, but I was born quite some time after that".
- Trademark Favorite Food: Instant pudding. He normally only helps magic princesses, but is easily bribed into helping Marco and later Janna with the prospect of pudding.
- Trickster Mentor: Especially with Ludo, Glossaryck acts even more whimsical because he can play on his general lack of confidence. Though he has been known to drop the whimsy when things get really dangerous.
- A Deconstructed Trope with Star in which while her spell use has matured under Glossaryck teachings their relationship has been hurt thanks to his cryptic messages and (perceived) betrayal.
- While usually a Trickster Mentor, sometimes he plays tricks on people for the fun of it. For example, pretending to have Came Back Wrong for months.
- In The Magic Book of Spells, Skywynne's chapter has a note from Glossaryck about his turning Rhombulus' hands into snakes. He told Rhombulus that he could learn a lesson from this. That "lesson" being, in Glossaryck's words, "that having snakes for hands is not easy."
- You Didn't Ask: His way of mentoring Ludo is teaching what Ludo asks him to teach, and only what he asks him to teach. That method leads to this line.
A cat-like fairy in charge of evaluating the magic of Mewni's queens.
- Berserk Button: Suggesting that her evaluation was a waste of time causes her to sequentially break down Star's mistakes one by one. Interrupting said evaluation also seems to be a pet peeve of hers, as Marco learned the hard way.
- Beware the Cute Ones: Baby may look cute, but she's quite stern, and although we don't get to see much of her angry side, the brief glimpse she gives Marco is terrifying.
- Big Eater: She eats an entire snack table that Marco spent all day preparing in an instant, and then asks for more. She also takes King River's food right out of his hands.
- Brutal Honesty: Downplayed; during the evaluation, the only thing Baby has to say about Star's multiple failed attempts to do proper magic is "interesting". After she informs Star that she failed the evaluation and Star pushes the issue, Baby loses her patience and gives Star a brutal "The Reason You Suck" Speech.
- Cute Kitten: A stereotypically adorable kitten.
- Dissonant Serenity: She is completely unfazed by Star's antics during the evaluation and she only comments that they are "interesting."
- The Dreaded: She's this not only to Star, but also to King River, who dislikes that she keeps taking all his food.
- Foil: To Glossaryck. She is more stern and strict when assessing Star's magic and skills, but more honest and direct in her training.
- Godzilla Threshold: Calling her in is usually a last resort, given how much River fears her. With the loss of Glossaryck, Queen Moon had no choice but to call her in as an alternative solution to evaluating Star.
- Meaningful Name: She resembles a baby kitten.
- Nightmare Face: Baby gives Marco one as she tells him to Get Out!!
- Older Than They Look: While she resembles a kitten, Baby has been evaluating princesses since before Queen Eclipsa.
- Our Fairies Are Different: She's a flying cat fairy.
- Reasonable Authority Figure: Doesn't let Star's antics get to her during the evaluation and gives her numerous tries to prove herself. She only loses her temper when Star pushes the issue and still allows her to pass when she ultimately pulls off the task that was assigned.
- "The Reason You Suck" Speech: Points out that Star was responsible for both breaking the royal wand and losing the family book of spells, she keeps many secrets from the people close to her, and her magic is so undisciplined that she can't perform basic spells.
- Sealed Good in a Can: When she isn't evaluating future queens, Baby resides in an ornate glass bottle.
- Sugar-and-Ice Personality: She is very polite and professional during the evaluation itself, but she gives Star one heck of a "The Reason You Suck" Speech afterward.
- Super Smoke: Turns into a very ominous cloud of black smoke to move quickly. She also conjures and banishes objects in puffs of it.
A seahorse from the Waterfolk Kingdom who is Pony Head's ex-boyfriend. Underwent a demoncism and now works at Reflectacorp Mobile.
- Ambiguous Situation: Despite being placed on house arrest, Seahorse is shown without his ankle monitor when he joins Pony Head in the fight against the Solarian Soldier.
- Amicable Exes: Pony Head dated him and broke up with him both times, with the second time ending with her telling him to take a hike. It seems they're only amicable enough for Pony Head to hire him and maintain a business relationship with him, as shown in "The Pony Head Show".
- A Dog Named "Dog": He's an anthropomorphic seahorse named Seahorse.
- Camera Fiend: In season 4, he becomes Pony Head's go-to cameraman.
- Gadgeteer Genius: Seahorse is a skilled hacker, and he hacked Reflectacorp compacts so that everyone who buys will be forced to watch Pony Head's broadcasts.
- Getting Smilies Painted on Your Soul: Seahorse underwent a demoncism which left him very docile and apparently incapable of negative feeling. He constantly talks like a stereotypical salesman.
- Made of Iron: According to Seahorse himself, he's unkillable.
- The Scapegoat: "The Monster and the Queen" reveals that Seahorse took all the blame for the false kidnapping of Eclipsa in "Queen-Napped", and was imprisoned for it. Now, looks like he's on probation/house arrest.
An eccentric friend of River who lives in the swamp of Bogabbah.
- Back for the Finale: He shows up in the final episodes where he helps River escort the fatally wounded Globgor to the Magic Sanctuary and away from Mina's invasion.
- Best Friend: To River.
- Body Horror: He has mushrooms growing on his head and he's all but stated to be part plant.
- Chekhov's Gunman: Eddie was initially introduced as a friend of River when he took Star for the Bog Beast Hunt. He would later serve as a guide to Moon and Eclipsa as they search for the increasingly powerful Meteora.
- Cloudcuckoolander: Let's just say that he's quite...eccentric.
- Expy: A wacky, older man with a mustache who's voiced by Rhys Darby? Eddie is pretty much the ''gorgeous man'' of Mewni.
- My Friends... and Zoidberg: He openly admits that he misses his family after their souls were stolen by Meteora, but he then adds that he does not care for Tim.
- Noodle Incident: He's been the "Bog Beast of Bogabbah" for two years; he cheerfully claims that he never learned his lesson.
- Too Dumb to Live: Yes Eddie, poking at the giant and highly dangerous Meteora to wake her up is a terrific idea that would have no consequences whatsoever.
- Too Spicy for Yog-Sothoth: He proves to be so eccentric that even Eclipsa is weirded out by him.
