Meteora Butterfly

Voiced by: Jessica Walter
Young Meteora/Heinous voiced by: Tress MacNeille
Baby Meteora/Heinous voiced by: Kari Wahlgren
Teenaged Meteora/Grobb voiced by: Bryana Salaz

The daughter of Eclipsa Butterfly and Globgor. She was a child of miscegenation and deemed a shame on Mewman culture. After her parents were crystallized, she was sent to St. Olga's to live under the care of robots. After being raised by unloving robots, she became its headmistress until she was dethroned by Marco and his revolution. After learning her true identity, she assaulted Mewni to reclaim her birthright, but was defeated and reverted to infancy by Eclipsa.

    As both lives of Meteora 
  • All Your Powers Combined: Being a hybrid gives her the best of both worlds. She has immense physical strength from her monster father and extremely powerful magic from her Mewman mother.
  • Boring, but Practical: The only spell she's shown using so far is a green beam from her eyes that sucks the soul of whoever gets hit by it. Which is dangerous, but sounds fairly unremarkable compared to the other Butterfly family members' spells, especially her own mother. However:
    • The spell is so fast that, unless somebody reacts right away, their soul is getting sucked.
    • It doesn't require any invocation or body movement whatsoever, meaning there's no real telltalle sign it's coming until it's too late.
  • Cat Folk: She takes some feline features from her father, which is best shown in her adult form.
  • Child of Forbidden Love: The child of a Mewman Queen and a notorious Monster Lord. Needless to say, Meteora's existence was considered a shameful one by Shastacan, the Magic High Council, and Mina Loveberry.
  • Color Motifs:
    • Purple. She has purplish hair, most of her clothing are various shades of it, her enlarged monster form's fur color purple, and her mother is associated with the same color. And when she's reborn, Meteora's eyes are magenta. And the wings of her butterfly form as a teenager are purple as shown in "Gone Baby Gone".
    • To a lesser extent, green. When she sucked the souls out of her victims in her past-life, her eyes glowed green. After learning to "dip down" in her second-life, Meteora's eyes also glow green and even produce green lightning. In "Cleaved", after dipping down to her butterfly transformation, her wings are green.
  • Cute Monster Girl:
    • Eclipsa's picture in the monster temple seen in "Monster Bash" has Meteora as a cute baby, with curly hair, pointy ears, and club markings on her cheeks.
    • Her actual half-monster, half-Mewman form is essentially a smaller, less monstrous version of her father.
  • Death of Personality: Her identity as Miss Heinous is effectively gone forever due to being reverted to infancy. Confirmed in "Gone Baby Gone" when an aged-up version of Meteora has no clue who Marco is but still distrusts him.
  • Does Not Like Shoes: Does not bother to wear shoes in her giant monster form after they got destroyed and wears footwear that does not cover her feet in Gone Baby Gone after growing to a teen.
  • Eye Beams: Her signature spell is a green beam coming from her eyes that allows her to suck the soul of whoever poor sap happens to get hit by.
  • Eye Motifs: Her eyes as Ms. Heinous are the sharpest of anybody in the Butterfly family, both times she uses magic it takes the form of Eye Beams, and when she undergoes any significant physical change, her eyes are a telltale sign (They go from black dots to gaining grey irises when she sucks the youth out of Princess Smoochy, they gain yellow sclera when she starts to turn more and more into a monster, and once she's de-aged into an infant, her eyes are notably different from her previous incarnation, having colored irises).
  • Facial Markings: When she gets agitated enough, black clubs appear on her cheeks, similar to the Butterfly family's Facial Markings. She puts herself through her own brainwashing to make them go away. After being kicked out of her school, she settles for using makeup to hide them. "Monster Bash" reveals them to be of the same nature as the ones of the Butterflies, since she is the daughter of Eclipsa.
  • Foil: Past-life Meteora was taken from her parents, unjustly stripped of her throne, raised by an abusive robotic mother who "taught" to be ashamed of her origins, and grew up to be an uncaring, crazy woman; Current-life Meteora can be properly raised by her loving parents who never teach her to repress her true nature, is given back the throne via Star, and shows that while she may be a Creepy Child with an Irrational Hatred toward Marco, she is capable of showing concern for others.
  • Half-Breed Angst: Due to the discriminatory nature of monster-Mewman romance, many think a child of such a union would be even worse. As such, in Meteora's first life, she was not well recieved by the Magic High Commission.
  • Happily Adopted: Happened to her twice. Horribly averted the first time. King Shastacan dumped her in the arms of the robotic Saint Olga who brainwashed her into becoming a cold and soulless woman. The second time, however, is definitely happy. She and Mariposa accidentally wandered into Hekapoo's dimension when they were infants and were raised as sisters by mountain women who named them Grobb and Bork respectively.
  • Horned Humanoid: She inheritted horns from her father's side, although unlike her tail, they're not there from the beginning and are instead traits she'll get once she's at least a teenager.
  • Hybrid Power: Mina at least thinks her hybrid nature makes her extremely dangerous, referring to her as 'the most dangerous monster in history,' which would mean she's more dangerous than Toffee. Which might not be so far off as seen in "Skooled" when she displays dramatically increased strength and durability to walk off a grenade. Worth noting, the same type grenade obliterated Rasticore's entire body instantly except for his arm, while Meteora isn't even scratched. "Tough Love" shows the other side of her hybrid nature: she can use magic by dipping down whereas normal monsters need the Wand to be capable of it. In the season 3 finale she proves so immensely powerful that she's more or less capable of conquering Mewni by herself and only someone on the level of Star, Moon or Eclipsa is capable of actually fighting her one on one. And unlike Ludo and Toffee, she doesn't need the Wand to do it.
  • Long-Lost Relative: She is revealed to be Meteora Butterfly, Eclipsa's half-monster daughter, meaning she is related to Star. Later subverted, when it turns out that Eclipsa never had any daughters besides Meteora, meaning the entire Butterfly line past Eclipsa are illegitimate heirs with no relation to the original royal family.
  • Lost Orphaned Royalty: Invoked. She is the child of Eclipsa and the Magic High Commission intentionally pushed for her removal from the royal family after they took care of Eclipsa.
  • Meaningful Appearance: Her overall appearance (as well as a few latent abilities) seem to change depending on her state of mind. As Heinous, years of psychological conditioning seem to have suppressed both her monster and butterfly family traits, a quick brainwashing session causing her cheek marks to vanish. Without access to her brainwashing machine, she was forced to cover her cheeks in make-up. As she slowly starts to remember her life before being sent to St. Olga's, her monster traits quickly start to surface, her arms going scales and claws, her eyes becoming reptilian, horns appearing on her head and a tail appearing. As she slowly becomes more and more unstable, she developed the ability to suck out the souls of other people, becoming larger and more monstrous in the process. Notably, after Eclipsa reverts her to infancy Meteora's eyes permanently turn magenta and her hair becomes bright purple. It is unclear whether this is a result of the change or her no longer repressing her true self.
  • Meaningful Name:
    • Her name as Miss Heinous is synonymous for wicked, loathsome and evil; fitting for a Knight of Cerebus villain such as herself. As it turns out, she got her name by King Shastacan calling her "heinous" as a baby and St. Olga mistaking that for her given name.
    • Her real name, Meteora, is based on the term meteor. Meteors are known to create powerful and destructive impacts when they crash into a planetary surface. In a literal sense, after embracing her monster lineage along with her inner Mewman magic, Meteora proves to be a dangerous threat as she leaves a trail of destruction and ruin on her quest for revenge. In a figurative sense, the revelation of her true identity as the interracial daughter of Eclipsa and her monster lover left an impact on both Star and the audience.
    • Meteora shares a name with an album by Linkin Park. Considering her taste in music and the album's themes of losing identity, it's appropriate.
  • Mythical Motifs: Meteora's backstory shares some connections with the Greek god Hephaestus. When Hephaestus was born, Hera was mortified by his deformities and exiled him from Mount Olympus. As he grew older, he grew more and more curious about his origins until he learned the truth. Hephaestus vowed revenge on Zeus and Hera for abandoning him, which he fulfilled by creating a golden throne and trapping Hera when she sat upon it. Zeus had to bribe Hephaestus in order to release Hera, by offering him a place in the pantheon. Like Hephaestus, Meteora was brought to Mewni, and King Shastacan disowned her out of shame for her genetics. Meteora was raised by robots and secluded from the knowledge of her heritage and lineage (Hephaestus was also known for robotics). When she discovered that she was the true queen of Mewni, she vowed revenge and unintentionally trapped Moon in the Realm of Magic when she attacked her, causing Star to look for Moon in the Realm of Magic and become similarly disorientated by the memory loss. When Meteora was reverted to infancy, she was brought back to Eclipsa and Globgor for a better future. Star gratefully gave Eclipsa the wand, saying her family stole it from its rightful owners.
  • Nigh-Invulnerability: She's absurdly tough to the point next to nothing is actually capable of hurting her. Moon's magic full blast or Star's Golden Super Mode is the bare minimum required to actually make her flinch and Star putting all her Golden Super Mode's power into one blast only managed to wound her. Note, a similar attack was sufficient to bring Toffee to death's door despite his ungodly Healing Factor, which means Meteora is harder to kill than the Immortal Monster himself. It takes an Unholy Nuke from Eclipsa herself to actually stop her.
  • Non-Human Humanoid Hybrid: "Monster Bash" reveals her to be the daughter of Eclipsa and her monster lover. At the end of the episode, she grows a reptilian arm and her face assumes a monstrous nature (green, pointy ears, yellow eyes). While at first mismatched, she eventually assumes a more evenly balanced combination of the two, before her soul-sucking rampage leads her to become a purple version of her father. Subverted as her mother is human after all albeit altered by magic.
  • Outside-Context Problem: Her entire existence is this to the Monster-Mewman conflict. The Monster-Mewman wars are very well documented, and both sides grew an absolute hatred of each other over the centuries of constant war. Even when Eclipsa fell in love with Globgor, both of them wound up crystallized without a hint that things went beyond a maligned romance. Then comes Meteora, the first Mewman-Monster hybrid to be publicly known (Tom and Celena were hybrids too, but the former is from a different kingdom and the latter's status was kept secret for a long time) and the heir to Eclipsa's throne. Naturally, nobody knows how to deal with her, and the Magic High Commission step in to help.
  • Patchwork Kids: A combination of both of her parents — She has her mother's eye shape, softer facial features, and Facial Markings (though they are different shapes); from her father, she has his pointed chin and ears, long nose, tail, claws, puffy hair, teeth, and horns. Meteora bares even more of a resemblance to her father after sucking a number of souls, thus having a more monstrous looking form.
  • Person of Mass Destruction: As Meteora, she's so immensely powerful she's more or less capable of destroying Mewni by herself. No wand, no army, just herself.
  • Playing Card Motifs: She has club-shaped markings. How this relates her to Star (hearts), Queen Moon (diamonds) and Eclipsa (spades) is yet to be seen. Until the midseason finale of season 3, when she's revealed as Eclipsa's daughter.
  • Plot-Relevant Age-Up: Happens to her twice. The first time was when Eclipsa turned her into a baby to stop her from destroying Mewni and killing Star. The second time happened when she and Marco's sister Mariposa got lost in Hekapoo's dimension and they grow into teenagers. When they come back to Earth, they turn back into babies.
  • Pointy Ears: Meteora's ears are naturally pointy.
  • Purple Is Powerful: Purple is one of her main color schemes and she has a huge amount of magical potential.
  • Really Royalty Reveal: Turns out to be Eclipsa's actual (only) child. She's not just royalty, she's been the only legitimate heir to the throne of Mewni for three centuries.
  • Rightful Queen Returns: Deconstructed, Meteora was abandoned by King Shastacan for being a child of miscegenation and was left at St.Olga's to be raised by robots. Meteora was taught to be ashamed of her monster traits and her name was changed to Miss Heinous, as the robot misinterpreted Shastacan's insult towards Meteora. By the time Meteora discovers her true identity, she completely loses her sanity and opts to conquer Mewni by absorbing the souls of anyone she encounters. While she was the rightful ruler of Mewni, she was far too crazy and dangerous to be given the title. Nefcy also stated that after conquering Mewni, Meteora would have destroyed the other kingdoms as well.
  • Super Toughness: After discovering her true nature, it turns out she's so tough that she can No-Sell a grenade powerful enough to obliterate most of Rasticore's body without a scratch, meaning if nothing else she's much tougher than him. Pretty much anything short of Moon, Star, or Eclipsa's magic can't even scratch her. An all out blast from Star's Golden Super Mode (IE, the same thing that left Toffee on death's door) is only enough to injure her.
  • World's Strongest Woman: Mina calls her 'the most dangerous monster in history', implying she's the most powerful monster in existence. Her performance in the finale heavily implies she was right. It takes being shot point face blank by Star's pure concentrated magic, then be immediately struck down by Eclipsa, explicitly the most powerful of the Butterfly Queens, to defeat her.
  • The Wrongful Heir to the Throne: Played with; Heinous/Meteora is a villain and the legitimate heir to Mewni's throne, not Star, Moon, or anyone else since Eclipsa. However, she's only a villain because of what was done to her, as an infant, to keep her from becoming queen. Additionally, there's no Succession Crisis involved; few people know who she really is, none of whom expect Meteora could become queen now—her attack on Mewni is less of a coup, more of a Roaring Rampage of Revenge directly at the whole kingdom's populace.
  • Your Soul Is Mine!: She has the power to drain people's souls upon regaining her true identity. Unlike Toffee, however, she doesn't need the Wand to do it, and can even do it as a baby if you really get her mad.

    Past-life Meteora/Miss Heinous
Click here to see her as a child

Miss Heinous was the headmaster of St. Olga's academy. A ruthless educator who abhorred the individuality the princesses displayed to the world and forced them to learn how to behave like proper ladies. She fell on hard times following Marco / Princess Turdina's uprise against her and the academy, having to live on her car with her helper and the remains of Rasticore, a killer that she hired to end Marco. She followed him to take her revenge on him but in the process recuperated her memories of being Meteora Butterfly, and decided to take revenge on the whole world instead, by reclaiming the throne that should be hers to begin with.

  • Abhorrent Admirer: Rasticore views her as one and awkwardly rejects her overtures at the end of "Skooled!" She responds by blowing him up, reducing him to an arm again, and taking his arm with her.
  • Arc Villain: The biggest threat to Star and Marco (as well as the entire kingdom of Mewni) following Toffee's destruction in the Season 3 premiere. However her mother defeats her at the season finale.
  • Alas, Poor Villain: Her defeat by Eclipsa doesn't have her saying This Cannot Be! or showing blind rage...instead it's her acting like a frightened, confused child who can't understand why her mother is hurting her and Eclipsa decidedly not wanting to do it.
  • Ambiguous Innocence: While more apparent when she regains her memories of being Meteora, it becomes apparent that many of her actions stem from having never matured emotionally or morally due to St. Olga's abuse. Meteora's rampage is less a monstrous, evil mastermind like Toffee, and more akin to an abused child lashing out at everything around her with little to no understanding her actions are evil.
  • Amnesiac Dissonance: Miss Heinous is a strict headmistress obsessed with order and maintaining the royal traditions by turning her students into "proper princesses". Ironically, as Meteora Butterfly her existence is a threat to the very royal traditions that she worked so hard to uphold.
  • Amnesiacs are Innocent: Inverted. She was much more innocent as Meteora than as Miss Heinous. It was ironically the act of removing her memories and turning her into Miss Heinous that turns her into a villain when she regains her true memories.
  • Antagonist Abilities: Her Your Soul Is Mine! Eye Beams, full stop. She also has super strength on par with the strongest monsters and toughness that is, at bare minimum, stronger than a Septarian's Healing Factor, but it's these eye beams, and her ability to use magic without the wand to boot, that makes her a nightmare to deal with.
  • Anti-Villain:
    • She's vengeful, neurotic, and strict, but she runs her school with the intent of hammering out the flaws that got her students sent there in the first place. Considering the fact that some of her charges almost burned down their kingdoms, threatened to murder people out of jealousy, and tried to steal the faces of fellow royalty, there's grounds to be made that she's not entirely in the wrong. Even Marco was impressed by her goals and the comfortable conditions of the institution, and only rebelled after taking issue with her more extreme methods of rehabilitation.
    • She also has every reason to be mad at Marco since his rebellion lead to her being thrown out of her own school and forced to sleep in a car. Her wanting him to be punished for it is entirely reasonable. Her wanting said punishment to be his gruesome demise and the fact she sees nothing wrong with the way she tried to brainwash her students is what keeps her in villain territory.
    • Subverted As "Princess Turdina" shows this is definitely not the case, because it turns out she's been craving power from the emotions of the rebellious princesses. In other words, everything above was all just bunk. But then came "Monster Bash", where she was revealed as an even bigger Anti-Villain than could possibly have been expected in that she is a half-Mewman, half-monster hybrid who was Brainwashed and Crazy into becoming the person she was. Her driving motivation afterwards is entirely sympathetic: she merely wants back what was stolen from her. That and rather than being a cold, calculating sadist like Toffee, she's a mentally unwell, abused child with way too much power.
  • Arch-Enemy: She sees Marco as this, since "Princess Marco" inspired the revolution which ultimately got her booted out of her own school.
    • As of "Skooled!", however, she has fully learned of her true identity, and "Turdina" has become an afterthought for her. As of "Divide" and "Conquer" she has made clear that she no longer considers Turdina her arch-enemy (though she still hates him and tries to kill him) and considers her true enemy to be the current Butterfly family, whom she considers usurpers, especially Star.
  • Ax-Crazy: Miss Heinous has devolved into being even more unstable and outright homicidal by her third appearance. After becoming Meteora again, it's clear she's decidedly not mentally well and more or less snapped completely.
  • Bad Boss: She kills the completely loyal Gemini in a fit of rage over Rasticore rejecting her.
  • The Berserker: After becoming Meteora, her fighting style has next to no strategy, mainly consisting of 'punch or blast everything in my path until it stops moving' and near constantly in a complete rage.
  • Big Bad: After being part of the Big Bad Ensemble in the first two seasons, she becomes the main antagonist of the third.
  • Big Bad Ensemble: With Toffee and Ludo for seasons 1 and 2, before becoming the sole Big Bad of season 3.
  • Blatant Lies: When Marco told his parents about her strapping him to a chair and trying to brainwash him, she called it a "gross exaggeration".
  • Boarding School of Horrors: St. Olga's is one to rebellious princesses, despite it being well-furnished with comfortable lodgings and excellent food.
  • Brainwashed and Crazy: Miss Heinous is a false persona that has been forced onto Meteora Butterfly through years of emotional abuse. Sadly when the brainwashing is broken, she ends up legitimately crazy.
  • Chainsaw Good: After his defeat, Heinous straps Rasticore's dimensional chainsaw to the hood of her car so she can travel the multiverse with it.
    • Like Toffee she's an incredibly powerful threat capable of threatening all of Mewni, are nearly impossible to meaningfully harm, have the same Your Soul Is Mine! power, and are in conflict with Star due to something one of her ancestors did. However, unlike the calm, collected, and calculating Toffee, Meteora is a completely insane, emotional, and rampaging berserker. Also, in their final battles with Star, the former obliterates Toffee (who is then killed off by Ludo) but Meteora was seemingly destroyed by Eclipsa but somehow reverted back into a baby.
  • Contrasting Sequel Antagonist: To Ludo and Toffee. Unlike either of them, Meteora has natural magic while the former two only possessed it when they had the Wand, and the only one to not be a pure monster.
    • Like Ludo, her abusive childhood left her with severe issues and leaves her gravitating towards any pseudo-parental figure she meets. However, unlike Ludo who was still able to be reasoned with and realize he had issues, thanks to being around Dennis, Meteora is completely incapable of comprehending she's wrong and impossible to actually be reasoned with because she had no one to properly look after her. Also, Ludo technically retained his royal status (only stealing his family home) but was raised by his Abusive Parents, while Meteora's status was forcibly taken from her and she was forced away by her loving parents.
  • Crazy Homeless People: After being kicked out of her school and being forced to live in her car, she's lost most of her sanity and desires revenge against "Princess Marco" for causing her current troubles.
  • Create Your Own Villain: The High Commission's actions regarding her directly lead to her becoming a gigantic threat.
  • Curbstomp Battle: Completely demolishes pretty much everything and everyone once her memories return and her monster side awakens. Only Moon and Star can fight her on sightly more even terms. Later on on the receiving end when her mother, Eclipsa, takes her out with almost no effort with only 3 spells.
  • Dark and Troubled Past: She was raised by the original St. Olga, an abusive robotic caretaker.
  • Dead Guy on Display: Wants to do this to Marco as a warning to the other Princesses.
  • Dean Bitterman: As Headmistress of St. Olga's, she's constantly this towards the girls in her care, taken further by her desire to outright crush them into blank slates.
  • Deconstructed Character Archetype: Of the Lost Orphaned Royalty. Her backstory sounds like it could have come from a fairy tale or Disney movie: a lost princess who had her throne stolen from her and was raised by an abusive guardian, who later finds out who she really is...but by the time she learns the truth, she's a bitter old woman, not a young girl who still has innocence in her heart and the potential to grow. Once upon a time, she was a sweet little girl, but being raised by an emotionally abusive robot caused her to grow into not a brave and kind heroine, but a deeply emotionally damaged person who cannot understand love and only understands how to inflict suffering. Her trying to take back her rightful throne is not a triumphant Rightful King Returns moment, but a destructive Suicidal Cosmic Temper Tantrum where she rampages across Mewni while sucking out the souls of innocent people, eventually having to be stopped by her mother Eclipsa who loves her but can't let her keep destroying the kingdom.
  • Didn't See That Coming: The defenses she set up to protect her school were designed with keeping princesses from breaking out and armies from breaking in. She never counted on princesses willingly going through the front door.
  • Disease Bleach: She has naturally bright pink skin and purple hair, but being forced to suppress her monster features turned both into pale, washed-out shades, making her look like a pure Mewman.
  • Disproportionate Retribution:
    • Towards herself, strangely enough. Her students get three strikes before they get a session with the institution's brainwashing machine. Heinous will use it on herself if she's unsure or unsatisfied with something as trivial as word choice.
    • She initially wants to kill Marco as Revenge, then do a Dead Guy on Display with his body as an example to the other escaped princesses.
    • She blows up Rasticore for rejecting her and tears out Gemini's Heart Drive.
  • Distaff Counterpart: To Ludo. Both had abusive parents who played a major role in their Start of Darkness and they also both have a tendency to gravitate towards any pseudo-parental figures that they meet.
  • Does Not Like Spam: When Eclipsa says they could do things together, like eat ice cream, Meteora says she hates ice cream.
  • Emotion Eater: Appears to be draining the emotions of the princesses to awaken her inherent power.
  • Empathic Shapeshifter: Her body gains more monstrous features after her memories start to return, and it turns into a full blown purple version of her father once she goes on a rampage.
  • Empathy Doll Shot: Finding a pair of old, dirty dolls resembling her parents in her old nursery starts to bring back her memories of being Meteora.
  • Et Tu, Brute?: She looks and sounds absolutely broken when her own mother decides to take her down once and for all. Not that it's easier for the latter.
    Meteora: You're on their side?! ... Mommy...?
  • Even Bad Men Love Their Mamas: Once she begins her Roaring Rampage of Revenge against Mewni, her mother, Eclipsa, is the only person Meteora shows any love or concern for. After taking over Butterfly Castle, Eclipsa's tapestry is the only one Meteora leaves intact. And when Eclipsa is forced to fight her to save Mewni, Meteora's reaction is that of absolute betrayal, a confused and frightened child asking why her mama is hurting her.
  • Evil Cannot Comprehend Good: She's taken aback when Gemini offers himself to replace the unconscious Princess Smooshy. This makes sense since nobody has ever treated Meteora with any form of love whatsoever. After Gemini's countless years of devotion and faith, Meteora ripped out his Heart Drive without second thought or remorse. As Gemini deactivates, his last words were that he would have died for her if she had asked him.
    • She's shocked when her mother turns against her to protect Star and the rest of Mewni, because as she sees it, the new Butterfly family are usurpers who stole from her and Eclipsa.
  • Evil Sounds Deep: After she regains her memories as Meteora, her voice gradually becomes deeper as she feeds on people's souls and becomes more powerful.
  • Fallen Princess: Being the daughter of Queen Eclipsa makes her this, with her birthright stripped from her as soon as her mother was crystallized.
  • Fangs Are Evil: Her true half-monster form has a wicked set of canine teeth.
  • Fatal Flaw:
    • Her selfishness. She feels entitled to act however she pleases because of her status and disdains anything that remotely suggests anything other than unflinching support for her selfish whims. This causes her problems because she constantly rejects actions by others that could help her issues simply because it doesn't fit with what she wants.
    • Her Never My Fault tendencies. She never even considers the possibility that she might be wrong in how she goes about things and feels completely justified in what she does to others because she always see herself as in the right. This leads her to lash out at others without a second thought and feel like she can whatever she pleases to them because of past slights.
  • Fisher Queen: The places she controls often have dark stormy clouds with black or dying foliage.
  • Flying Car: Her car can fly, presumably having been enchanted somehow.
  • For Want of a Nail:
    • Her life wouldn't have been as tragic had her Mewman stepfather and the Magic High Commission not hid her away and struck her name from all records out of monster prejudice. Fortunately she was given a second chance when Eclipsa (unwittingly) magically regressed her into a baby again.
    • On the other hand, she represents what would've happened if the Magic High Commission decided to target Tom, too, since he is also a royal half-breed born to a Mewman and a monster.
  • Freakiness Shame: Meteora was taught to suppress her monster lineage during her time at St. Olga's and when her cheek marks appeared in "St. Olga's Reform School for Wayward Princesses", she panicked and immediately went to the machine to suppress her marks.
  • Freudian Excuse: Miss Heinous was raised by an emotionally abusive robot that forced her to repress her monster side and never showed any kind of care or love for her, leading to Heinous current personality, her need to repress individuality on everyone and, when the truth comes back to her, she completely loses it.
  • Glamour Failure: Her cheek marks start to appear whenever she feels strong emotions. Later, her appearance becomes more monstrous as she starts regaining her memories of being Meteora Butterfly, until her true monstrous appearance stuck.
  • Half-Breed Discrimination: She was swapped out with a peasant girl when she was an infant, due to Eclipsa's mewman husband and the Magic High Commission not wanting a half-monster to rule the kingdom and was raised by Saint Olga, who taught her to hide her half-monster features and Facial Markings and brainwashed her to make her forget of ever being Meteora.
  • Hate Sink: In her first appearance, her desire to crush the individuality of her students leaves very little about her to like, moreso than even Ludo and Toffee, whose motives are to some degree sympathetic. In subsequent appearances, her growing insanity and Laughably Evil traits moderate this somewhat, and she turns out to be a subversion later on by her tragic past and The Reveal of her true identity which make her a Tragic Villain.
  • Hellish Pupils: Meteora's monster form has yellow eyes with slitted pupils.
  • Hidden Depths: The strait-laced former headmistress obsessed with prim and proper perfection listens to heavy metal music and even headbangs! And that's not even getting into her true backstory.
  • Hide Your Otherness: Her robot adoptive mother forced Heinous to hide her clover cheek marks and monster features such as her tail even though Heinous liked them.
  • Hoist by Her Own Petard: She invokes this when she uses the brainwashing machine to erase her Blush Sticker. It also allows her to find Marco's hairpin and trace it back to Earth.
  • Hybrid Power: She inherited her father's Sizeshifter abilities and her mother's Magic Genetics, manifesting as the ability to grow larger, stronger and more monstrous through Your Soul Is Mine! Eye Beams.
  • Identity Amnesia: She has been living as Miss Heinous for centuries after having her memories of being Meteora Butterfly erased by Saint Olga's.
  • I Just Want to Be Normal: Willingly exposes herself to her own brainwashing techniques to achieve this, however fleetingly. It turns out that this was part of brainwashing that was done on her to make her forget who and what she truly is.
  • Inadequate Inheritor: She was denied the throne for being a monster hybrid and was subsequently abandoned to be raised by robots.
  • Jerkass: She's a decidedly unfriendly person.
  • Judge, Jury, and Executioner: Miss Heinous sees herself as this, passing off judgment and then meting severe punishment to those who violate the laws of St. Olga's. In "Heinous", she wants to kill Marco and display his bones in retaliation for the revolution he started.
  • The Juggernaut: As Meteora. More or less everything in her path gets steamrolled except for Moon, Star, and Eclipsa, and only the latter two are actually capable of meaningfully harming her one on one (and of the two, only Eclipsa is capable of doing so without putting her entire mana pool into one blast).
  • Knight Templar: As headmistress, she brainwashes princesses because she believes Individuality Is Illegal and leads to chaos. She will force her personal sense of justice on those who defy conformity. After realizing who she truly is, her motive to retake what was stolen from her when she was a baby is completely understandable, but she's willing to cause a lot of damage to do so.
  • Laughably Evil: In season 2, the loss of her school/home has driven her mad, so she attempts to get revenge on Princess Marco with what meager resources she can get her hands on. Her assassin is dispatched by an unrelated threat (read: disintegrated by a gift card) and her attempt to bargain with Marco's parents leads to a sarcastic apology that flies right over her head. By Season 3, this is completely gone and she means business.
  • Literal-Minded: In "Heinous", she believed Marco was sincere in his video to the princesses despite his apology being obviously sarcastic. This works to Marco's advantage because he's confident that princesses won't break with the way he presented his apology. Justified because she was raised by robots who similarly do not understand sarcasm.
  • Loss of Identity: This is a huge part of her character arc. She was once Princess Meteora, but she got Brainwashed and Crazy, never to remember anything of her past life. For years, she had struggled to find out who she was, but to no avail. All that time, she defined herself by her will to take away other people's identities, and that was all that mattered to her.
  • A Love to Dismember: Surprisingly and disturbingly. After Rasticore tries to walk out on her, she reduces him back to nothing more than an arm, then talks to his still moving arm affectionately and takes it with her.
  • Luke, I Might Be Your Father: Discovering that she is also a Butterfly, Star was not too thrilled with the idea of possibly being related to her, so she demanded her mother to look into it. Star became even more disappointed when it turned out Meteora was Eclipsa's only daughter, and she was swapped with another, meaning not only is Star not related to Meteora, but she was never related to Eclipsa to begin with.
  • Mark of Shame: Her stepfather king Shastacan saw her as such. He saw her as a bastard child of Eclipsa and he scornfully replaced her with a peasant baby upon Eclipsa's crystallization. It didn't help that Meteora was a hybrid of a monster and a Mewman.
  • The Mind Is a Plaything of the Body: It is shown that many of her more distinctive physical qualities - including the clovers on her cheeks and the various monster characteristics she inherited from her father - are suppressed through Saint Olga's brainwashing methods and will routinely subject herself to them if they begin to surface. When she loses the school to "Princess Turdena's" uprising (and her brainwashing equipment along with it), she is forced to hide them with make-up as she begins to suffer a Sanity Slippage and starts to remember her true identity.
  • Necessarily Evil: When the reform school was destroyed, the princesses essentially became destructive anarchists. Considering that some of the princesses who were committed to the school were hostile and destructive to the public, Miss Heinous may not have been entirely wrong in her methods. Problem is, the lengths she will go to curb chaos are brutal and extreme. Downplayed later on when its shown that the princesses do maintain a semi-functional school with decent order and respect.
    • It is later revealed that she had less noble intentions, but it's then revealed even later that those intentions are partly the result of brainwashing done on her.
  • Never My Fault: Completely ignores any responsibility she could take for her own more "heinous" actions in favor of blaming Star and Marco.
  • No Infantile Amnesia: She was able to recognize her original name and identify various features of her nursery, even though she was still a baby by the time St. Olga adopted her. That said, she can't actually remember anything beyond that and needs to actually look up answers on her own.
  • No-Sell: Princess Arms throws a grenade at her and she isn't even scratched. Worth noting, the same type of grenade obliterated most of Rasticore's body instantly. Most of Moon's attacks have next to no actual effect on her, and it takes putting her full power into it for Meteora to actually feel it. It takes someone with incredibly powerful magic to have any hope of actually meaningfully hurting her at all.
  • Obviously Evil: Really, what did you expect from some lady named Miss Heinous? Eventually she becomes a subversion, as she's revealed to be a Tragic Villain who is the victim of Mewni's monster prejudice and years upon years of emotional abuse, which influenced her personality greatly as she grew older.
  • Obliviously Evil: It's apparent that rather she's Miss Heinous or Meteora, she is incapable of understanding her actions are evil. This is likely because St. Olga's raising was more about trying to make her 'normal' than actually teaching her right from wrong.
  • Omnicidal Maniac: As revealed by Daron Nefcy during a podcast, Meteora wouldn't have stopped at Mewni if she had won, instead going ahead and destroying everything else that she came across, until there was nothing left.
  • One-Woman Army: By the time of the finale she doesn't have any minions left. She doesn't need them.
  • One-Winged Angel: Discovering who she really is causes her to begin reverting to her true, hybrid form. Not only does she look much more monstrous, she's clearly much more powerful than before.
  • Parental Abandonment: Her real parents (Eclipsa and Globgor) weren't there to raise her, but they didn't have much of a choice in the matter, as they had been both crystalized. Her stepfather on the other hand, was willing to abandon her because she was half-monster, and left her at a certain boarding school...
  • The Perfectionist: A firm believer that all princesses must be absolute perfect princesses, a.k.a. mindless blank slates who simply obey and never show any individuality. St. Olga's memory banks imply she gets it from her.
  • Playing the Victim Card: In "Heinous", she presents herself to Marco's parents as an innocent victim of Marco's actions, greatly downplaying her own misdeeds.
  • Power Limiter: Her brainwashing was also acting like this, keeping her ignorant of her true hybrid nature and power. Once it's removed, she shows why Mina called her 'the most dangerous monster in history.'
  • Promotion to Opening Titles: In season two, she appears amongst the gathering of characters at the end of the title sequence.
  • Psychopathic Womanchild: Underneath her prim and proper exterior Miss Heinous can be very childish and violent, shown first when she planned to punish Princess Marco by ripping out her spine and putting her on display in front of the school. Taken even further when she regains her memories of being Meteora and transforms into her full hybrid form. She callously kills off Rasticore when he starts to show second thoughts and also murders her loyal servant Gemini in the process. When she sees Eclipsa holding her childhood doll she reverts to a very childlike personality, referring to Eclipsa as "Mama" and cradling her like a doll. Predictably she throws a monstrous tantrum when Eclipsa begs her to stop her rampage and give up on claiming the throne of Mewni. At her core, Meteora is basically an abused child in a grown up body lashing out at everything around her. When Eclipsa begins attacking her, her reaction is basically a scared, confused child who can't understand why her mother is hurting her.
  • Raised by Robots: King Shastacan gave Meteora to St. Olga, a robotic nurse who raised her. The pitfalls of this trope, specifically St. Olga's lack of emotions and rigid programming, caused the robot to teach her "daughter" to be ashamed of her monster features and to suppress any individuality.
  • Rasputinian Death: Defeat in this case. After she completely takes everything thrown at her and has conquered Mewni, it takes being hit by several spells from Star's Butterfly form, then being struck by her pure concentrated magic, then being attacked by Eclipsa, the strongest queen, without being given a chance to heal, before finally succumbing to one of Eclipsa's spell.
  • Really 700 Years Old: Her mother is Eclipsa, who was Queen of Mewni three centuries prior, making Miss Heinous around the same age. Justified by both her half-monster heritage and her emotion-stealing machine being able to restore some of her youth as well.
  • Revenge: Her goal in season two; She even hires Rasticore to hunt down and destroy Star and kidnap Marco. Now she wants justice against the Royal Family and take the throne.
  • Riches to Rags:
    • After being ousted from St. Olga's, she and her assistant are forced to live in a rundown apartment complex, with very little money. As of "Heinous", her fortunes have dipped even further, as she now lives in her car.
    • This happened to her at birth, as she was (and still is) the rightful heir to the throne. Eclipsa's Mewman husband and the Magic High Commission swapped her out with a peasant girl when she was an infant, due to not wanting a half-monster to rule the kingdom.
  • Sanity Slippage: By her third appearance, her mental state has taken a major nosedive. She is utterly obsessed with getting revenge on Marco (at one point even voicing the desire to kill him and put his skeleton on display at St. Olga's as an example for future rebel princesses), carries Rasticore's arm around everywhere and treats it like her baby, and even displays a Twitchy Eye while filming Marco's "retraction". It worsens once she realizes who she really is, and goes in a much more dangerous direction.
  • Sarcasm-Blind: Marco filled his "apology" to her with sarcasm so that the rebellious princesses wouldn't believe it, and Miss Heinous took it at face value.
  • Self-Fulfilling Prophecy: Mina calls her 'the most dangerous monster in history', and others seemed to have agreed...and it was precisely the actions taken to try and Un-person her for that reason that turned her into just that.
  • Self-Serving Memory: She tries to downplay the horrible things she did to the princesses when talking about how Marco wronged her and when bringing up how they blew up Rasticore, ignoring the fact that he was trying to kill them.
  • Shadow Archetype: Meteora represents what Tom could have become had circumstances been different for them. They were born into royalty, had one Mewman parent, and are both powerful magic users. But Tom got to keep his heir status, while Meteora was essentially abandoned and "erased" out of racial disgust, and left to an abusive robotic caretaker. Tom grew up a Royal Brat with issues that he later learned to control thanks to the positive influence of his friends, while Meteora had no one to rely on, and thus she eventually became a Tragic Villain who internalized the emotional abuse she received as a very unhealthy coping method. Also, while both did have loving parents, Tom was able to grow up with his while she was forcibly separated from hers.
  • Silver Vixen: She doesn't look half-bad in her full hybrid form, despite being over three centuries old and visibly elderly as Miss Heinous. In any case, Gemini was smitten with her. This is because she's half-Mewman, and her mother's species are known to be incredibly long-lived.
  • Sinister Schnoz: She has a long, pointed nose which her monster form also has.
  • Skewed Priorities: In "Gift of the Card", she sends her assistant to spend the last of their money on her favorite hair dye.
  • The Slow Path: While her mother Eclipsa spent 300 years in stasis, Meteora lived out those years leading to the time Eclipsa was freed.
  • Soft-Spoken Sadist: Miss Heinous always maintains a low voice, and she is ruthless in maintaining order in St. O's, quickly stamping out any form of dissent or individuality with impunity.
  • That Woman Is Dead: Her response at the end of "Monster Bash" when Gemini addresses her as Miss Heinous.
    Gemini: Ooh, there's too much heat out there. We should get going, Miss Heinous.
    Meteora: That's not my name.
    Gemini: I'm...sorry?
    Meteora: My name is Meteora.
  • Tragic Villain: The episode "Skooled!" reveals the original St. Olga was an unfeeling robot that acted as Heinous' "mother" and abused and brainwashed her into becoming prim, proper and "normal" by suppressing her half-monster heritage. The abuse essentially turned her into a carbon-copy of her foster mom, who believed subjecting princesses to the same torments she was subjected to was for their own good.
  • Tomato in the Mirror: It turns out that Miss Heinous is a false persona given to Meteora Butterfly through brainwashing, and it is a huge shock to Meteora when she regains her memories of who she truly is.
  • Took a Level in Badass: After no longer suppressing her half-monster powers, she's able to curbstomp all of the Princesses in St. Olga's, and even rips off Ponyhead's horn. She ends the episode stating her intent to reclaim her birthright, the throne of Mewni.
  • Ungrateful Bastard: Loyalty isn't her strongest suit. She remorselessly removed Gemini's heart to explode Rasticore when he rejected her, in spite of the fact that the former served her devotedly and the latter repaid his debts to her by help her retake the school. She also killed Saint Olga without hesitation, though she had it coming. Justified, as Saint Olga's raising was shown to be utterly devoid of anything resembling compassion or love, so naturally forming meaningful bonds with others is anything but her strong suit.
  • Unperson: Every hint of her existence as Meteora was erased from Mewni historical records.
  • Unskilled, but Strong: Is one of the most immensely powerful creatures in the series, having immense physical strength and durability and the ability to 'dip down' and use incredibly powerful magic even without the Wand...but her 'fighting style' generally consists of 'smash or blast the thing I want to hurt until it stops moving'. Justified as she's essentially an abused little girl throwing a super destructive tantrum.
  • Used to Be a Sweet Kid: The records of St. Olga show her as a nice and kind girl in her childhood.
  • Vague Age: While the show establishes that she is about 300 years old, due to her hybrid nature and the fact that some monsters are known to live thousands of years it's difficult to tell how old she is relatively. At the start of the series she appears to be middle-aged or older, however after her transformation in "Skooled" she looks almost like a young adult. Compounded by the fact that she has naturally grey hair and pale skin, even as an infant.
  • Villain Decay:
    • Goes from being a Knight of Cerebus and Hate Sink in her first episode to a pathetically vengeful, petty, and Laughably Evil villainess with instances of Stupid Evil in her third appearance.
    • Her fourth appears to be playing her up as a serious threat again, considering she will drain others dry of their emotion for power. Her fifth appearance has her magic fully awaken and reveals that she's Eclipsa's daughter, referred to by Mina Loveberry as "the most dangerous monster ever", something which "Skooled!" shows isn't entirely off the mark. And following that, she becomes the single strongest opponent Star has ever faced, fully reversing the trope to the highest degree possible.
  • Villain Has a Point:
    • She tells the Diazes they should keep a closer eye on their child, something they take to heart.
    • When she and Eclipsa meet up, Meteora bluntly states that she wants the throne of Mewni, but Eclipsa replies she can't give that to her. Meteora replies back that the throne is their's by birthright. And, she's technically correct in a sense. The Magic High Council lied about Festivia being a descendant of Eclipsa, thus making all subsequent Queens of Mewni false heirs.
    • In her fight with Star in "Conquer", the latter tries to stop their battle by saying they could fix all the problems caused by her family. However, Meteora quickly retorts that Star can't fix what her family's done. Even with all the damage and destruction that Meteora is responsible for, she's right. No matter what Star's good intentions are, she can't erase the centuries worth of transgressions and wrongdoings committed by her family.
  • Villainous Breakdown: In a extremely heartbreaking manner, after Eclipsa starts attacking her, she breaks down like a child who can't understand their mother is hurting them. Which in essence is exactly what's happening.
  • Walking Spoiler: It's very difficult to talk about Miss Heinous without mentioning the elephant in the folder.
  • Woman Scorned: Rasticore tries to walk out on her after she spent months nursing him back to health when he was just an arm. In response, she reduces him back to an arm, then disturbingly takes it with her and talks to it as if he's still whole.
  • Woobie, Destroyer of Worlds: She's Eclipsa's daughter, born from the union of a Mewman and a monster. Rather than let a monster become Queen of Mewni, the Magic High Council made her an Un-person and Eclipsa's human husband gave her to St. Olga, a robot that emotionally abused her and brainwashed her since infancy to be "normal" turning her into the exact kind of monster obsessed with forcing other princesses into being "prim and proper" like herself. She fully gives into her half-monster heritage, plotting to take back the throne that always belonged to her.
  • Would Hurt a Child:
    • She initially wanted to rip out Princess Marco's spine in retaliation for "her" actions, and we see she's willing to order a kamikaze attack on the students, who are either children or in their early teens.
    • She snaps off Pony Head's horn in "Skooled". For a race of flying unicorn heads, that's probably tantamount to having all of your limbs amputated. It results in Pony Head having a having a massive Heroic BSoD.
  • Wrong Genre Savvy: She believed exposing "Princess Marco" as a boy would convince the rebel princesses of the need for "structure" in their lives, causing them to welcome her back with open arms. Instead, the princesses have no problem with Marco being a boy, and still despise Miss Heinous.

    Current-life Meteora
Meteora as a teenager/Grobb.

The current version of Meteora, a little baby with surprisingly powerful abilities that is being raised by her parents once again.

  • Amnesiac Villain Joins the Heroes: When Eclipsa reverted Meteora to infancy, she removed a majority of her memories from her past life. However, the memory erasure wasn't perfect as she still hates Marco (albeit subconsciously) but doesn't know why.
  • Amnesia Missed a Spot: Retains her past self's hatred of Marco, though she doesn't remember why.
  • Berserk Button: She has shown to have an extreme hatred towards Marco.
  • Beware the Cute Ones:
    • The Thousand-Yard Stare she gives Marco at their first meeting makes him wonder exactly how certain they are that her memories are gone for good. When we see her aged up into a teenager, she doesn't exactly remember anything from when she was Miss Heinous.
    • "Meteora's Lesson" shows that she is still capable of dipping down despite her age, and she's powerful enough to stagger Toffee.
  • Brainy Baby: Despite being an infant, she's able to understand Glossaryck's instructions.
  • Cheerful Child: She's surprisingly friendly towards others (aside from her subconscious hatred for Marco) as seen in her interactions with Glossaryck, Star, and Mariposa.
  • Child Prodigy: A Brainy Baby who is able to "dip down", something that Glossaryck only teaches to Queens late in their training (except for Star, and even then she could only do it in her teens).
  • Creepy Child: Has this behavior despite being a baby, particularly towards Marco, not helped by the fact that appearance is that of a devil child.
    • In "Butterfly Follies", she is first seen running off Marco's bed, climbing onto the ceiling, and then twisting her head around; Star is obviously and understandably disturbed. And then, when Marco greets Meteora, she gives him a Thousand-Yard Stare complete with ominous music.
    • In "Ransomgram", she chops off the heads of dolls and started leaving some in Marco's with a mole on the same place as him.
  • De-power: Meteora lost much of her power after being regressed into infancy, and when we see her use magic as a teenager, she's only at Star's level. Possibly because she's working only with her own innate magic, without eating people's souls as a power-up.
  • Easily Forgiven: Grobb/Teenage!Meteora is. Neither Star nor Marco seem to particularly hold the fact that she basically tried to sacrifice Star to give Mariposa magic powers against her.
  • Exorcist Head: She can turn her head 180 degrees while crawling on the ceiling.
  • Freudian Excuse: She and Mariposa are very paranoid, aggressive, and manipulative, but it's to be expected for children who grew up alone in a Death World like the Neverzone.
  • Girls Love Stuffed Animals: She is often seen in the company of a stuffed toy.
  • Hairstyle Inertia: If her teenage self is anything to go by, Meteora will have the same hairstyle as when she was an infant.
  • Hate at First Sight: When Meteora/Grobb meets Marco for the first time in the Neverzone, she doesn't hide her dislike of him in the slightest. She doesn't know why she hates him, lacking her memories as Miss Heinous, she simply does.
  • Irrational Hatred: She retains the hatred her previous life had for Marco, but without the memories of how the hate fostered in the first place, meaning as far as she knows, she hates Marco just because.
  • Irony: Meteora absolutely loathes Marco but becomes best friends with Mariposa, his younger sister who will most likely grow to strongly resemble him in her teens.
  • Nurture over Nature: Unlike her adult counterpart, "Meteora's Lesson" shows that this version of her is capable of showing concern for people besides herself.
  • Raise Her Right This Time: After Eclipsa defeats her, Meteora is reduced back to infancy, and Eclipsa takes her and returns to her husband so they can finally be the family they always wanted to be.
  • Shared Unusual Trait: She shares Heinous' dislike of Marco, which is pointed out as a worrying sign she retained some of her memories. We find out in "Gone Baby Gone" that she doesn't remember anything from when she was Miss Heinous, but she dislikes Marco, meaning it may just be her.
  • Smash Sisters: With Mariposa/Bork while they were in The Neverzone.
  • Troubling Unchildlike Behavior: She seems to still have some kind of grudge against Marco. She threatens him by leaving decapitated dolls in his bed, including one with a familiar mole on its right cheek.
  • Wall Crawl: She can climb up walls with ease.
  • Winged Humanoid: Unlike her previous life, this Meteora managed to unlock her Butterfly form during her time in the Neverzone, giving her a pair of butterfly-like wings on her back.
