Main Heroes

General

The two main characters that battle the Forces of Evil.

---

• Affectionate Nickname:
  • One of Star's best friends, Pony Head, calls her "B-Fly."
    • Her demon ex-boyfriend Tom calls her "Starship."
    • Buff Frog calls her "Sweet Potato".
  • Hekapoo has her own nickname for Marco in his adult body — "Muscles". From Pony Head, it's "Earth Turd".
• Back-to-Back Badasses: Both fight monsters together on a regular basis.
• Badass Adorable:
  • Star's cute and peppy like a box full of puppies, and attacks with cute magic spells to match, but she's just as dangerous.
  • Marco can kick monster butt and is also a 14-year-old boy that gushes over kicking said monster butt, has a thing for safety, and is also cute as a button.
• Badass Pacifist:
  • In "Mr. Candle Cares", Marco manages to finally get through to Tom that his questionable actions won't make Star like him back and only make her hate him more. And this was in the middle of a ping-pong match to the death. And Marco didn't win the match, he only used his words.
  • In "Sleepover", Star manages to wing against the Truth & Punishment Cube by using a Logic Bomb.
• Bash Brothers: They are best friends and both love to kick monster butt together, though this starts to move into Battle Couple territory as they develop feelings for each other.
• Befriending the Enemy:
  • Star befriended Buff Frog after his former allegiance to Ludo.
  • Marco befriended both Pony Head and Tom after their brief jealous feud.
• Berserk Button:
  • Star hates being underestimated, as Marco told her at the end of "The Banagic Incident". Though she got the context of Marco's comment wrong (He was more worried about her lack of understanding Earth concepts while by herself inadvertently causing trouble from it which did indeed happen. She thought he meant she wouldn't complete her "quest" without him). This also slightly came into play in "Blood Moon Ball" when she felt that Marco thought she couldn't take care of herself, despite him just following after her out of concern.
    • Since having to step up as interim queen, condescension has become a major Berserk Button for her, especially when it's coming from her own castle staff. In "Divide", she knocks one of her knights unconscious with her wand for repeatedly calling her "baby girl".
  • Don't manipulate Marco's love of Mackie Hand movies. His reaction was enough to scare Tom, a necromancer and powerful demon of Hell, when he did that in "Friendenemies."
• Beware the Nice Ones:
  • Star, for all of her bubbly and sweet personality, can be terrifying when the situation calls for it.
  • Marco is a sweet and thoughtful kid, but also has karate skills that border on Charles Atlas Superpower.
• Big Brother Instinct: Both of them. Star towards Meteora, whom she sees as her younger sister, and Marco towards Mariposa, his biological sister. They are protective of their respective younger sisters and want them to have the best life possible.
• Blessed with Suck: "Curse of The Blood Moon" reveals that the Blood Moon cursed them to fall for each other against their wills. Even Eclipsa doesn't understand why Star and Marco would want to get rid of a good thing. Marco and Star feel that it's only made their lives miserable. And Here to Help entirely erases the idea that it ever had influence over their feelings.
• Character Development:
  • Parodied with Star in "St. Olga's Reform School for Wayward Princesses". Although she does manage to power through her fear and infiltrate the place, she is still (rightfully) terrified of St. Olga's.
    Star: So I've overcome my worst fears and became a better person, blah, blah, blah, now let's get out of here!
    • She initially believes monsters to be the most ruthless of creatures with no shred of goodness in them at all. However, in "Lobster Claws", she starts to have some second thoughts after her interactions with the titular monster. More notably, in "Mewnipendence Day" she realizes the people of Mewni weren't completely innocent in their feud with the monsters, and she starts treating the monster Buff Frog better.
    • In "Storm the Castle," Star realizes that despite Marco being adventurous like her, she can't risk his life pointlessly and recklessly on her various escapades. She also treats Buff Frog like an equal and warns him before the castle blows up.
    • This all comes to a head in season 3. Gradually shifting from the romantically-challenged Boisterous Bruiser she was in seasons 1 and 2 to a queen-to-be, mentally and emotionally maturing as a result. She tries to get her fellow royals-in-waiting to wisen up and starts campaigning against monster cruelty, something that's plagued her kingdom for centuries.
  • Marco gradually becomes more confident in himself. Specifically, in regards to Jackie, he goes from having a bad case of Cannot Spit It Out to being able to smoothly have casual conversations with her.
    • In "St. Olga's Reform School for Wayward Princesses", Marco gets over his reasonable animosity towards Pony Head to help bust her out, as well as the other princesses.
    • He gradually grows out of his "safety conscious" nature. Makes sense, considering all the time he spends with Star fighting monsters has likely changed him.
    • As a result of Marco's adventures with Star, he slowly turns into a Blood Knight who very much enjoys fighting monsters and getting in danger. This results in him moving to Mewni after growing bored living on Earth and even sneaking out to have adventures with Hekapoo when Star can't.
• Deconstructed Character Archetype: Star and Marco deconstruct the typical friends to lovers, Everyone Can See It dynamic. The two are extremely close and comfortable with one another, but while they develop feelings for each other, it takes them both a while to realize it since they're still emotionally immature teenagers. What's more, these revelations come about while the other is in a relationship, with people they have genuine chemistry with that came about since they're under the impression that they were Just Friends. Rather than one of them confessing and triggering a Relationship Upgrade, in both cases they only admit it under duress and it makes things more awkward between the two of them, and put a strain on their relationship with their respective partner. In short, such a dynamic is unlikely to be neat, tidy and causes a lot of heartbreak for everyone involved.
• Determinator:
  • Star works very hard towards her goals, so much so that she'll sometimes end up greatly sleep-deprived.
  • Marco is extremely tenacious, especially in the face of characters that underestimate him for being human. This trait comes into play in "Running With Scissors" when he spends 16 years hunting Hekapoo down just to prove that he is stronger than he seems.
• Elephant in the Living Room: From season 2 onward, Star and Marco have developed crushes on each other but both are desperate to lose these feelings despite it being known to each other and their companions. They go on with their lives as usual, so they can go away on their own, rather than talk to each other about them.
  • They even go as far as to go to Hell itself to undo a potential love curse they accidentally partook in, rather than actually talk to each other. With Star only questioning at the very end about the curse's involvement in their feelings for each other.
  • They finally step aside and just talk about their feelings with no curses or other love interests to get in the way late in season 4, and officially become boyfriend and girlfriend.
• Kid Hero: Both are 14-15 years old and are co-protagonists.
• Embarrassing Nickname:
  • Star is given the title of "Star the Underestimated" but it's not the best idea to underestimate her. Of course given the titles generally reflect the defining trait of the royal in question, that might be exactly the point.
  • Everyone knows Marco as the "Safety Kid" because he once wore a helmet in the gym showers.
• Establishing Character Moment:
  • Star is introduced beating up monsters and wrangling wild unicorns in a pretty dress, wildly riding said unicorn through the streets of town and into her parents' throne room, and... accidentally setting her hometown on fire with her new magic wand.
  • Marco is introduced assuming he's being called to the principal's office because he's a "bad boy", and being sorely disappointed that the principal wants the school's resident "Safe Kid" to show the new exchange student Star around the school. Marco then rants about how he's tired of being known as "the Safe Kid" while steering Star away from various minor hazards.
• Facial Markings:
  • Star by default, they're shaped like hearts. Since her mother has diamond-shaped ones and some other Butterfly family members like Etheria also have them (Etheria's are small stars), they appear to be genetic.
  • Marco in "Deep Dive"; in a moment of desperation, he uses Star's wand and locates her using the All-Seeing Eye spell, and he briefly has crescent-shaped cheek marks that glow when he recited that spell.
• Fatal Flaw:
  • Star has a bad habit of dismissing others when they try to warn her. This has put her in trouble that she has only managed to avoid by sheer luck.
    • Owing to her rather sheltered upbringing, Star's optimism and enthusiasm can border on recklessness, to the point of endangering people around her with her madcap antics. She has rather simplistic views on concepts such as leadership and responsibility, believing that prioritizing fun above all else matters the most. All this, coupled with her lack of understanding of Earth customs, often puts her and Marco in strange, dangerous situations.
    • As of "Bon Bon the Birthday Clown", Star has trouble venting her emotions when she is in an uncomfortable situation, the main example being creating destructive green spells when suppressing her feelings for Marco. In some cases she can become too kind for her own good, for example she invited Jackie to a concert with her and Marco, but it fueled her envy towards Jackie at the end of the episode. Granted, there have been instances where Star has shown apathy towards Marco's suffering, but it was because she knew that Marco would survive the experience unharmed, but God help anyone who puts Marco in grave danger. It's even taken further in Season 3, where apparently, she has trouble being honest with herself, to the point that she's focusing on her princess duties so to avoid her emotional troubles.
  • Marco's self-confidence is quite fragile and he craves respect to the point that he'd beat up an (admittedly mean-spirited and bratty) 8-year-old to avoid getting laughed at.
    • Pride. A surefire way to make an enemy of Marco (or more often than not, cause him to act rashly) is to attack his ego. Some pithy insults from Hekapoo got him so wound up to prove himself worthy of dimensional scissors that he spent 16 years chasing her so he could prove her wrong.
    • As of season 3 he's developed a far stronger desire for adventure and danger to the point where it alienates most of his friends and family on earth and even has difficulty functioning in his own home dimension.
• Force and Finesse: Star is the destructive magic Force to Marco's trained karate Finesse.
• Green-Eyed Epiphany:
  • Star originally was all for Marco and Jackie dating but the minute Marco and Jackie went on a date, she was consumed by jealousy.
  • Seeing Star kissing Tom is what finally shatters Marco's denial and makes him realize he has romantic feelings for Star.
• Green-Eyed Monster:
  • Star in "Bon Bon the Birthday Clown" shows her increasingly uncomfortable whenever Marco and Jackie have a moment despite initially being happy that she didn't have to go with him to the dance because Jackie asked Marco out instead. Worse, the spikes of jealousy seem to be unconsciously triggering negative green magic from her wand.
    • In Star and Marco's Guide to Mastering Every Dimension (which "canonically" is written post-Bon Bon), some of Star's hidden jealousy pops up when talking about Jackie: first, in Jackie's bio, Star says she's "surprisingly alert for someone who looks like she just woke up". And in an interview with her, Jackie goes on a whole page about how she actually does have a crush on Marco too. Star awkwardly ends the interview after that, and (before the "start" of the interview) notes that she doesn't feel it should be included in the guidebook.
  • Marco after the events of "Lava Lake Beach" when Tad helps Marco realize that he's in love with Star, Marco's jealousy has soured his once-amicable friendship with Tom, causing him to act cold and hostile to Tom whenever he's reminded that Star and Tom have gotten back together. Examples include him getting disgusted at the displays of affection between them in "Monster Bash", and in "Stump Day" when he accuses Tom of forgetting Star's birthday and being a bad boyfriend to her.
• Guys Smash, Girls Shoot: Played with. While Star is a Magical Girl princess who mostly uses her wand to blast her opponents, Marco is a Badass Normal who engages his opponents in hand-to-hand combat with karate. That said, Star is quite comfortable punching out monsters.
• Interspecies Friendship:
  • Marco is a human, while Star is a Mewman. And both have often said to each other and different people that they are each other's best friend.
  • The duo also form friendships with humans (Janna, Jackie-Lynn, Ferguson, and Alfonzo), monsters (Buff Frog and his babies), flying pony heads (Pony Head), demons (Tom), and Wooletts (Kelly).
• I Just Want to Be Special:
  • Marco hates to be labelled as the boring, safe kid and wishes for a more exciting and dangerous life. His wish was granted when Star moved in with him.
  • Star is a notable one only in that she tends to flip flop between this and I Just Want to Be Normal for various reasons. In this case, since day one she's been overexcited and enthusiastic about using her magic wand, and beyond it being a family heirloom, she personally loves the magical potential it allows to the point that within a few months of using it she does almost nothing without it.
• Lady and Knight: Star was a princess of Mewni and Marco was her squire until he ascended to knighthood. Marco's fellow squires and knights believe he only got to be a squire because he's dating Star. He wasn't at the time.
• The Lancer:
  • In "Heinous" Star is depicted as Marco's second-in-command after Marco lead a revolution in St Olga's Reform School.
  • Marco is Star's squire (in name only however) and he is her most trusted friend and most reliable knight.
• Like Parent, Unlike Child:
  • Star is upbeat and energetic to the point of being almost hyper. Her parents are stodgy, deadpan, and display a tiny bit of strictness. Although, her father is secretly as boisterous and adventurous as Star. As for her mom, she was far more mature than Star was at the same age, and lived a more normal life before her mother died.
  • Marco, despite his protestations to the contrary, is a very safe person, to the point he does it almost unconsciously. His parents, however, are free spirits who embrace new experiences even if they are dangerous. Downplayed in that Marco wants to be more like his parents.
• Masculine Girl, Feminine Boy: Zigzagged. Both Star and Marco have traditional qualities of femininity and masculinity, respectively. However, each of them has also shown other traits of the other gender attribute as a part of their personality.
  • Star loves wearing pretty clothes, cute things, and is very interested in boys. And out of her and Marco, she is the most aggressive and willing to use brute force first rather than talking.
  • Marco is an avid martial artist who finds Star's Fight Magnet status a plus and can be just as Blood Knighty as her... except he also acts as the Only Sane Man of the two, even acting as a sort of Team Mom to her and their friends, and he's quite In Touch with His Feminine Side.
• Maybe Magic, Maybe Mundane: As far as the nature of the Blood Moon Curse that they were subjected to, it's quite unclear if it was ever a real curse, or a purely psychological phenomenon that functions off of how much one believes in it. Marco initially claimed to not believe in it, but the fact that he saw a connection between him and Star from mundane objects felt out of the ordinary forced him to think otherwise. Likewise, Tom did believe the curse was real as far as he knew when he used it, and it seemed to work exactly as it should after Marco was chosen by the blood moon, but now rejects the notion that there was ever magic involved in their feelings for each other. The blood moon shining on Star and Marco could be read as having a placebo effect of bringing out their feelings towards each other. On top of that, the Severing Stone erasing that moment could also be read as a placebo that made Marco think he doesn't have feelings for Star and only furthered his denial.
• Meaningful Name:
  • "Star" represents her being The Heroine of the story and her bright personality; "Butterfly" alludes to her imaginative, if flighty qualities, as well as her growth during the series.
  • Marco manages to be this and Ironic Name. In Italian, "Marco" means "Mars" (the Roman God of War); it fits with his love of fighting monsters and liking Star's Fight Magnet life.
• Mythical Motifs:
  • Star has a Unicorn motif as shown by her close friendship with Pony Head, her introductory scene riding a Unicorn, the tiny unicorns that power her wand, and the unicorns she created in The Realm of Magic.
  • Marco has a small Dragon motif as shown by his dragoncycle, the dragon designs decorating his dojo, and when he uses Star's wand it appears to have dragon wings.
• Nice Guy: Star is a friendly, helpful, and good-hearted individual, and Marco is a kind and supportive person, who cares deeply for his loved ones.
• Official Couple: As of the episode 'Here to Help'.
• The Power of Love: In the series finale "Cleaved", their love manages to create a final portal from the Realm of Magic before it's destroyed for good, which then causes a Merged Reality so they can be together without causing an I Choose to Stay moment (them both choosing each other over their home realms may in fact have been what triggered this event).
• Prophecy Armor: According to Star, Father Time gave Star a photo from the future showing the pair enjoying their time at the beach. Suggesting that Star and Marco are guaranteed to survive everything that's thrown at them until they reach that point in time.
• Red Oni, Blue Oni: Star is the energetic and wild Red Oni and Marco's the safety-minded and level-headed Blue Oni.
• Savvy Guy, Energetic Girl: Star is very active and excitable compared to the calmer and safety-conscious Marco.
• She Is Not My Girlfriend: Both Star and Marco have said this about each other at some point.
  • In "Camping Trip", Star's father assumes that Marco is probably Star's boyfriend and outright refers to Marco as such later, to which Marco hastily replies, "I'm not her boyfriend!" He also says this to Higgs when she bitterly accuses him of getting to the same squire position she worked hard for by just being the princess' boyfriend.
  • When speaking to the guidance counselor Mr. Candle, he suggests that she should be getting around to finding the "future king of Mewni" and asks her under Tom's orders if she has a secret crush on Marco. She implicitly denies it, saying that she and Marco are just roommates who are friends and that having a crush on your roommate would be weird.
  • Marco actually inverts this when he learns that Mr. Candle works for Tom and is spying on them to make sure Star and Marco aren't a couple. He goes into Mr. Candle's office for an impromptu second career counseling meeting to say that he's going to be king of Mewni when he grows up. Then he goes into detail about how he and Star are "smooch buddies... on the lips." All of this is a ploy to lure out Tom.
  • After "Face The Music", this trope is very much in full effect.
• Solar and Lunar: Marco has several connotations with the moon after to his involvement in The Blood Moon Ball. Star's magic on the other hand has connotations with sunlight. This is shown with her magical form which has a golden glow of sunlight and her magic itself is golden.
• Strong Girl, Smart Guy: Star has lots of magic power at her disposal, while Marco is a safety-obsessed Neat Freak who tries his best to teach her about Earth culture.
• Strong Family Resemblance:
  • Star looks exactly like her mother in her youth, save for the different hair color and Facial Markings.
  • While Marco inherited his father's hair color, eye color, and skin complexion, his face shape is more similar to his mother's.
• Stupid Sexy Friend: Despite having their own respective crushes on other people, both Star and Marco each show an awkward physical attraction to the other at some point. Perhaps inevitably, they end up catching feelings.
• Sword and Sorcerer: Marco is capable of fighting enemies twice his size, with his bare hands. He also became a master swordsman through hunting Hekapoo. Star is a prodigy with magic and relies on her wand while in combat. When she gave away her wand, she started doing it with her bare hands.
• Sympathetic Adulterer:
  • Star — Along with Marco, they both feel overwhelmed with guilt when they kissed in "Booth Buddies". Because not only is Star in a relationship with Tom, but also because Marco is her squire. They only kissed because they thought the booth was magical and they had to do it to free themselves. Marco clearly doesn't want to break Star and Tom's happiness and just wants to move on from this.
  • Marco — He committed emotional adultery with Star while he was with his then-girlfriend Jackie. As in he secretly ran away to see a girl who has feelings for him and proceeded to live with her for a few weeks. However, he was being Innocently Insensitive and he tried to make it up to Jackie.
• Threesome Subtext: Both with Tom in the Season 3 finale. Star and Tom are dating, Star and Marco are best friends with Unresolved Sexual Tension and Tom and Marco have become increasingly close over the course of season 3, with their Ho Yay nearing Ship Tease. Meteora calls Marco Star's other boyfriend and at the end of Season 3, the three share a triple hug.
• Tiger Versus Dragon: When Star and Marco argue, they represent this trope. Alternatively, they represent this trope when fighting enemies.
  • Star is the tiger because her magic is affected by her emotions. She tends to allow her emotions to affect her decisions. Examples include: refusing to help an enemy because she believed that monsters were naturally evil and irredeemable, angrily believing that Marco saw her as helpless and in need of rescue from Tom (despite Marco being Properly Paranoid). Finally, she tried to bury her feelings for Marco because she feared that she would ruin their friendship or ruin his relationship with Jackie.
  • Marco is the dragon because he is the most rational and logical when making decisions but it has gotten him in trouble. Primarily because these dimensions have different laws and traditions. This trope is best shown in two episodes: when Star and Marco try to save the bounce lounge, Marco tried to tell her that she should accept the change to preserve her nostalgia. However, Star refused to listen and valiantly tried to save it. This is also shown when Marco and Star became babysitters for Buff Frog's children, Star disregarded the rules so that the children can have fun, but, Marco insisted that they follow Buff Frog's instructions.
  • This dichotomy is also shown when the pair fight enemies as Marco uses his martial arts skills to win, whereas, Star uses devastating magical attacks to quickly win fights.
• Took a Level in Badass:
  • The first episode shows Star being a total Inept Mage despite her great fighting prowess. Come the season 1 finale, she was able to summon magic with so much control and power, she could easily Curb Stomp several monsters and blow up the nigh-indestructible crystal jail Marco was imprisoned in by Toffee. In the first episode of Season 2, she learns how to use magic without the wand (dipping down). And in the 4-part Season 3 premiere, she cleaves her wand back together and gains a new Golden Super Mode, which she uses to curb stomp Toffee, seemingly killing him. Later on, Star learns to enter it willingly and cast magic without using her wand.
  • Marco became an accomplished fighter during his time in Hekapoo's dimension, and retained these skills when he left. He demonstrates his new skills when he goes toe-to-toe in a sparring match with Star and is able to counter all her attacks.
• Trademark Favorite Food: Both of them really like eating Captain Blanche's Sugar Seeds cereal.
  • Like the rest of Mewni, Star really likes corn.
  • Marco likes to eat Cornplex bars so much, that Star calls it his "favorite guilty pleasure snack".
• Unresolved Sexual Tension: By Season 3, it's clear that both of them have feelings for each other, but because Star is dating Tom at the time (whom she also likes), neither can act on them. This was exemplified in "Divide". Star hides her blushing cheeks after seeing Marco demonstrate his fighting abilities when he volunteers to fight Meteora. A few moments later after having a hug, they are interrupted by a chef. Both Star and Marco are blushing as they try to hide their hug by doing an awkward handshake.
• Will They or Won't They?: With two seasons' worth of increasingly obvious Ship Tease under their belt, this trope is officially in play between Star and Marco as of "Starcrushed", now that Marco is completely aware of Star's crush on him and is clearly uncertain of how he feels about it. Even more so once Marco develops feelings for Star himself and cannot act on them due to her having gotten back together with Tom. "Here to Help" (3 episodes prior to the series finale) delivers the answer: they will.

Star Butterfly, the Underestimated

"Mewni should be a place of peace and unity for everyone. But for that to happen, we need to stop following the old ways. We need to be the change we want to see."

Voiced by: Eden Sher (English), Kana Ueda (Japanese), Pip Pellens (Dutch)

"Star the Underestimated
was queen for just four days.
Her one decision on the throne:
To give it all away."

A magical princess from the other-dimensional Kingdom of Mewni who is sent to Earth by her parents for safety's sake in lieu of sending her to St. Olga's Reform School for Wayward Princesses after misusing the magic wand she received on her fourteenth birthday. Lives with her earthly hosts, the Diaz Family.

She also loves to fight against monsters, but eventually comes to realize that monsters aren't so much as mindless enemies, but rather an entire race of people who have been systematically mistreated by Mewni's government. In turn, she resolves to fix the government's mistakes by trying to bridge the gap between monsters and Mewmans, being a very forward-thinking princess. She eventually abdicates the throne for Eclipsa, the rightful queen at the time, and becomes her primary advisor.

---

• 0% Approval Rating: Due to a mix of revealing that she had lost the Spell Book and Glossaryck to Ludo and abdicating the throne and the wand to the pro-monster Eclipsa, as well as having pro-monster opinions in a Mewman-Monster segregated society, Star becomes something of an object of ridicule and hatred to Mewmans, enough for her to be chased out of a town with torches and pitchforks the moment they realize who she is in Season 4. On the flip-side, monsters have developed an adoration towards her.
• Abdicate the Throne: At the end of season three, Star gives the throne (and wand) back to Eclipsa, who had technically been the legitimate ruler for the last three hundred years. A moot point after the Grand Finale, because there is no longer a Mewni to be the queen of when Earth and Mewni are fused together.
• Achievements in Ignorance: Ironically, since Star has a poor understanding of magic's rules and limitations, she occasionally ends up overcoming those limits without even realizing it. Special mention goes to reaching through the All-Seeing Eye spell without causing it to explode and reviving the Realm of Magic after Glossaryck said it was impossible. Even her "normal" spells qualify, as Glossaryck points out that they aren't in the spellbook yet somehow function anyway.
• Action Girl: Magic is actually new to her, but she has been kicking monster butt for a long time.
• Aesop Amnesia: The Aesop in "Storm The Castle" was that she shouldn't endanger the lives of others (mainly Marco's) when she's on one of her thrill-seeking adventures, or when she's reckless on the pair's dimensional travels. However, in season 2, she regularly forgets this and has gotten Marco and herself in a lot of danger.
• Alien Catnip: Star loves sugar and likes to put massive quantities of it onto everything — inventing the "sugarrito" (a burrito smothered in sugar). Her favorite cereal on Earth seems to also be an example based on the name: "Captain Blanche's Sugar Seeds". Justified as Mewni's main food staple (to a ridiculous degree) is corn. Cornbread, popcorn, corn on the cob - but nothing sugary, even candy corn. Having such a low sugar diet until coming to Earth likely helped accentuate Star's sugar sprees.
• All Girls Want Bad Boys: Subverted. Star falls head over heels for Oskar after learning he has a record, and her ex Tom is a demon. However, she mentions breaking up with the latter because of his anger issues and gets over her crush with the former when she starts to fall for Marco and then renews her relationship with Tom when he matures.
• All-Loving Heroine: As she matures, Star becomes more and more determined to have Mewmans and Monsters be friends with one another.
• Ambiguous Situation: At the end of "The Battle for Mewni" Star is trapped inside Ludo's wand fragment and Toffee shatters it with her still inside. Shortly after this happens, Star has a conversation with Glossaryck (who was also recently killed) in an empty black void before rediscovering her magic and popping back into existence. It is hard to tell whether Star died and was talking to Glossaryck from beyond the grave or if she was put in some sort of limbo after the fragment was destroyed. "Deep Dive" reveals that it was actually neither. Star was in a place called "The Realm of Magic" which is apparently where all magic in the universe comes from. Glossaryck's ambiguous status still holds true, though.
• Ambiguously Bi: Star is mostly interested in guys, such as Tom, Oskar and Marco, but she is pretty comfortable with StarFan13's crush on her and has seen some women through Crush Filter, such as Chloe and Brunzetta, the latter of which she is hinted to be interested in, since her cheek marks crush when she says she doesn't remember her.
• Ancestral Weapon: Her wand has been passed down a very, very long line in her family.
• Anguished Declaration of Love: Star confesses her crush on Marco in "Starcrushed" and admits that she initially suppressed her feelings for him because she hoped that they would go away.
• Attack! Attack! Attack!: She's not exactly one for strategy and relies heavily on her wand and fighting skills. Showcased in "St. Olga's Reform School For Wayward Princesses" where her main plan to save Pony Head was to rush in and blast everything. Marco has to convince her to use infiltration and stealth for most of the trip since that would bring the entire school's guards on them. She only falls back on it when Marco is captured in order to free him and to pull a quick escape.
• Became Their Own Antithesis: In Seasons One and Two, she was firmly against the idea of becoming queen and having to accept responsibility, to the point that she nearly mauled an innocent mermaid she knew by name to get out of being queen. Come season four, when given a vision that her destiny is to destroy the realm of magic to stop Mina and save the monsters, Star reluctantly decides to do it because it's the only solution as opposed to waiting out the apocalypse in a tavern, though it will mean she and Marco will be separated forever, and Glossaryck will die again.
• Be Careful What You Wish For: In season two, she hated being told that she would become queen of Mewni, no matter what she did, because it would mean having to be responsible like her mother. Come season three, she longer has to worry about that...because she finds out she's not related to Eclipsa, the rightful heir to the throne and in fact gives the throne back to her. She comes from the Pie Folk instead.
• Because You Were Nice to Me: Downplayed. While she isn't ignorant of Glossaryck's negative traits, she also admits that he's still an important person to her because he trusted her judgement and didn't try to tell her what to do like what many others try to.
• Beware the Silly Ones: A goofy teen who has experience kicking monsters' butt on a daily basis.
• Beyond the Impossible: At the end of "The Battle for Mewni" she manages to come back to life after being trapped in the Realm of Magic and drowning in Toffee's corruption.
• Big Sister Instinct: Star thinks of Meteora as her little sister, and she grew to be protective of her since being deaged. Star wants to make sure she grows up surrounded with good people and great friends.
• Blood Knight: Even before receiving her magic wand, she enjoyed kicking monster butt. Apparently her parents used the Royal Guards, all of whom are trained warriors in their own rights, as her babysitters. It's no wonder she grew up thinking violence and battle are fun when those guys taught her how to snap the necks of her stuffed animals when she was a toddler.
• Bodyguard Crush: She has unknowingly developed a crush on Marco and only started to subconsciously act on it in "Bon Bon the Birthday Clown". Marco was originally trusted to be Star's guide to Earth culture when Star's parents asked the principal to find a guide for her. Marco also protects her and the wand from Ludo and other villains or when she gets herself into trouble due to misunderstanding Earth culture.
• Break the Cutie: Hoo boy. The multiverse seems intent on breaking her naivete at every possible opportunity. Over the course of the series she has seen her best friend brainwashed by a corrupt boarding school, been forced to destroy her wand under threat of having her other best friend brutally murdered in front of her, seen her friend and tutor abducted right in front of her and was helpless to stop it, set up her friend with another girl only to realize that she has feelings for him, had said crush revealed in front of her entire kingdom, and been left to die in an ocean of corrupted magic. Last but not least, she learns in "Butterfly Trap" that her family are illegitimate heirs to the throne and her entire identity as a princess is a lie.
• Brilliant, but Lazy: "Baby" reveals that Star's magical aptitude is on par with Queen Eclipsa, but her lack of discipline makes her spells extremely chaotic and unfocused. The only time that she can reliably get her magic to do what she wants is when something important is on the line. Star also never bothered to learn basic magic, because it bored her, noted since the apple test in "Baby" is geared (as shown in "The Hard Way") to be easily passed using Levitato, literally the most basic spell in the book. Instead Star skipped to much more advanced stuff and even created dozens of her own spells (even ones that create life from nothing) without giving the slightest thought to how they worked, as seen at the end of "Raid the Cave" when Star begins writing her own notebook of spells, she had to cast a Narwhal Blast before writing the entry because it comes so naturally to her that she'd never paid any attention to the mechanics of the spell before.
• Broken Pedestal:
  • "Mewnipendence Day" has Star realizing that the holiday in question is a case of Written by the Winners and the conclusion that her people have been annually celebrating the slaughter of innocent monsters proves upsetting, to say the least.
  • At the beginning of "Starstruck", Star deems Mina Loveberry, the greatest warrior to ever live. She turns out to be just as crazy as Marco said she was. Star admits this as well by the end of the episode, calling her "a lady with no marbles". She regretfully admits during a late episode in season 4 that she used to look up to her.
  • To Moon, when she is revealed to have been behind the things that the Magic High Commission and Mina caused. Although Moon tries to explain how she was trying to de-radicalize them by finding less violent solutions, Star refuses to hear her or to forgive her. Of course, their mother-daughter relationship has never been the best to begin with, and when it came down to that moment, Star felt like her mom just ruined her life in general. However, Star learned from this experience and from her own experience with Eclipsa that mothers are flawed, and that she should not be quick to condemn her mother as a bad person just because she made a bad decision. Star later concludes that her mother needs to be reminded that she should always have her family to help her through when she makes these kinds of mistakes.
• Brought Down to Badass: She's unable to use her wand for most of "Quest Buy", but still manages to run and fight circles around Ludo and his thugs. Happens again in "Marco Grows a Beard" when her wand is caught up in a mass of Marco's beard that she overgrew and that she had to both navigate through and contend with Ludo and his minions to retrieve it.
• Butt-Monkey: To a much lesser degree than Marco, but Star meets her fair share of Amusing Injuries, too.
• Calling Your Attacks: She usually says what she wants her magic wand to do or summon out loud. Occasionally a spell backfires (or just fizzles) if she says the wrong thing.
• Cannot Spit It Out: When Star is interacting with or even thinking about a crush then she can't compose her sentences correctly, which has caused her problems when she tried to speak to Oskar and only acted out on her crush during "Mewberty". This also applies to Marco, though in this case it's to preserve the friendship and allow Marco to be with Jackie. In "Starcrushed", when interrogated, Star reluctantly half-confesses to her friends, and only gives Marco the truth when it's seemingly the last time they'll see each other.
• Catchphrase: "So cute!" and "Hugs!"
• Character Tic: Chewing on her wand seems to be her tic considering how often she does it. She doesn't do it as much in season 2, hasn't happened once in 3.
• Cheerful Child: Despite being 14 years old, Star has the charisma and energy of a little child. This becomes subdued by the end of Season 2, where she is forced to mature more.
• Childhood Friends: She and Pony Head have known each other since they were toddlers.
• Class Princess: While she was a student at Echo Creek Academy, Star was admired by her classmates for her magic powers and her friendly, energetic personality. She easily stole the spotlight everywhere she went, much to the fury of Alpha Bitch Brittany.
• Clingy Jealous Girl: In "Bon Bon the Birthday Clown" when Marco actually goes out on a date with Jackie, Star gets increasingly jealous, calling him 57 times, and it gets to the point that it causes her to lose control of her magic. She even used her magic to spy on their date, and inadvertently caused them to crash on Jackie's skateboard.
• Color-Coded Wizardry: Her magic glows different colors depending on the situation. Normal spells cast using her wand are pink, dark magic spells glow green, and spells she casts by "dipping down" are light blue. At the end of "The Battle for Mewni" when she reclaims her magic from Toffee it turns bright yellow.
• Color Motifs: Yellow. Star has blonde hair, it's one of her two favorite colors (besides blue), and when she "dips down", Star glows bright yellow, as well as her controlled mewberty version being yellow with some orange tones.
• Combat Pragmatist: Has absolutely no problems using whatever advantage presents itself, during fights.
• Comically Invincible Hero: During season one, she was this. Ludo's forces were laughably compared to her, who could blast them with or without her wand, the result of the fights were usually having Ludo's army comically battered. Season 2 onwards subvert this, as more powerful and complex enemies appear to her, such as Ludo's powered version, Meteora and so on.
• Comically Missing the Point: Star does this a lot, but it's justified because she's not entirely aware of how things work on Earth. For example, she once thought that a football game was going to be an actual battle since everybody around her made it sound like it was going to be a battle, when really they were just being metaphoric to pump up the hype.
• The Conscience: In season 4, Star becomes a sort of impromptu royal advisor to Eclipsa.
• Crippling Overspecialization: Star is very good at combat magic, but she apparently skipped over a lot of basic and practical spells to focus solely on fighting bad guys. This comes back to bite her in the ass hard during her magical evaluation with Baby when she spends all day trying and failing to move an apple a few feet. To make matters worse, that particular test is designed to be easily passed by casting literally the most basic spell in existence, Levitato.
• Crouching Moron, Hidden Badass: Star may seem a bit like a ditz with hardly any control over her wand, but when it comes to fighting, she's surprisingly competent to the point that she can use the wand without mucking up anything. And she's quite good at fighting without the wand, having done so for most of her life before inheriting the wand on her 14th birthday.
• Cuddle Bug: Gives out "Hugs!" to her friends and loved ones on a regular basis.
• Cute Monster Girl: Star Butterfly herself looks like a fourteen year old girl with heart tattoos on her cheeks. She transformed temporarily into a monsterous butterfly-like form during mewberty, yet still looked adorable despite being terrifying. Her controlled transformation is considerably less monstrous.
• The Cutie: Star has the mindset, energy, and innocence of a child. This becomes subdued by the end of season 2.
• Damsel out of Distress: In "Blood Moon Ball", Marco heads to the titular ball in what he thinks is a rescue, only for Star to one-shot a furious Tom to save Marco.
• Destructive Savior: When she attacks, few things will be left unharmed, including Marco.
• Didn't Think This Through: Her recklessness tends to get her in trouble.
• Did You Just Punch Out Cthulhu?: In the finale, she defeats the all-powerful Mina Loveberry, a warrior of the Solarians, an army designed to wipe out monsters, by erasing the magic in the Realm of Magic alongside Moon, Eclipsa, and Meteora.
• Dimensional Traveler: Originally from Mewni, a kingdom in another dimension. She casually travels between different dimensions using magic scissors she has. When she gets control over her mewberty form, it's revealed she can open portals at will.
• Distracted by the Sexy: When seeing adult Marco in "Running With Scissors", she barely listens to him, is entirely focused on his six pack and couldn't compose her sentences. In "Ransomgram", Star is outright fawning over Marco's adult form and Brunzetta.
• The Ditz: Downplayed, as she isn't really stupid, just incredibly naive and childish. At others times though...
• Dork Knight: Star is an excitable teenager who is learning to use her magical wand and is a notable warrior against several enemies of her kingdom.
• Dub Name Change: In many dubs, either her first name or last name is translated to the word for "star" or "butterfly". In the Norwegian dub, her name is "Sara".
• Dude Magnet: Quite a few boys have crushes on her, with Tom, Marco and Oscar being the main ones, though it's clear that several background characters also find her notably attractive.
• Dumb Blonde: She's not dumb per se, but she is quite scatterbrained in that she has the behavior of a child and tends to interpret figures of speech literally.
• Easily Impressed: Due to being a Funny Foreigner from another dimension, she's utterly dazzled by even the must mundane of Earth customs, which includes electricity.
• Eating the Eye Candy: In "Running with Scissors", Star is left dazed as she stares at the toned torso of an adult Marco.
• Empowered Badass Normal: Was capable of kicking serious butt even before getting her wand. Even without it, she's quite the possible fighter and by season 4, she uses magic without her wand pretty freely.
• Even the Girls Want Her: StarFan13 admits to having a crush on Star in "Sleepover".
• Everyone Can See It: Star's emotions are visible through her cheeks and often move and glow depending on her emotions. Her crush on Oskar is seen by everyone due to this and she is incapable of being subtle around him even to a point where she can't talk to him without displaying her emotions. She also confirms this in "Sleepover" where she says that everybody knows that she has a crush on Oskar. This is downplayed in Marco's case as she isn't aware of her complex crush on him suggesting her emotions are shown when she is aware of them but her wand was subconsciously effected by her envy in "Bon Bon the Birthday Clown".
• Everything's Better with Rainbows: Star frequently makes rainbows appear from her wand, sometimes helpful, sometimes catching on fire.
• Everything's Better with Sparkles: Star enjoys things that sparkle and has at least one spell that includes the words "sparkle" and "glitter" at the same time.
• Expressive Accessory: Her Facial Markings function like this, as they've changed according to her mood in various episodes. For example: skulls when she's sad or violent, light bulbs when she gets an idea, or spinning hourglasses similar to a loading icon for a computer mouse when she's bored. This gets subdued in later seasons, but can still happen occasionally.
• Extremely Protective Child: Star has shown to be very protective of her parents, and later, Eclipsa.
  • She was already adamant over going back to Mewni to fight Toffee, but listened to her mother to not to... until she learned from Buff Frog that Ludo had imprisoned her father. She immediately snuck out and went to angrily confront Ludo over what he did to her father.
  • She imprisons Eclipsa because her interference in Moon and Meteora's fight led the former to go missing.
  • Star is aggressive in her approach to find the culprit(s) who tried to yada-yada Eclipsa and who kidnapped her in "Yada-Yada Berries" and "Queen-Napped", respectively.
• Fallen Princess: After giving Eclipsa back her throne, Star is not the acting queen or princess, having apparently removed herself entirely from the line of succession (or rather, honored that she and the last several queens were never technically part of it). However, Star still has magic she can perform without the wand and Queen Eclipsa lets her stay in the castle anyway, and hopes her decision is worth it. Indeed, despite being her senior, Eclipsa treats Star much like a very trusted adviser, which convinces Star to stay even when her parents move away.
• Fantastic Racism: Initially believes monsters to be the most ruthless of creatures with no shred of goodness in them at all. However, in "Lobster Claws" she starts to have some second thoughts after her interactions with the titular monster. More notably, in "Mewnipendence Day" she realizes the people of Mewni weren't completely innocent in their feud with the monsters, and she treats monsters like Buff Frog better in "Storm the Castle". Come season 3, Star has dropped her previous racist beliefs of monsters and is now attempting to improve relationships between monsters and Mewmans.
• Fight Magnet: The source of most of the combat in the show is villains simply trying to get her wand and rule the multiverse.
• Fish out of Water: During her first day on Earth, Star treated a light switch as if it was magical, mistook a drinking fountain for a hostile creature, and failed to see a connection between Mr. and Mrs. Diaz and Marco, despite knowing his surname, because she just assumed that all Earthlings had the same surname.
• Five Stages of Grief: Goes through them during the last few episodes in the finale especially after finding out of her mother's treachery:
  • Denial: A small bit, but she was unable to understand why her mother would help Mina.
  • Anger: "Pizza Party" through the first half of "The Tavern at The End of The Multiverse" has Star condemning Moon for betraying not just Mewni, but her personally as her mother, and refuses to talk to her.
  • Bargaining: Star unhesitatingly goes to Glossaryk to see if there's a way out of the mess she's in, and she declares the only solution to stopping Mina is to destroy the magic. Then Glossaryk asks how she's supposed to do that, places her in the Grandma Room, then her dead ancestors point her to her completed tapestry...which shows her doing exactly that, with everyone she knows safe and sound.
  • Depression: Star is hesitant to carry out the plan while everyone on Mewni will be safe as shown in the vision, she also realizes Marco is not there. Glossaryk tells her Marco will survive the endeavor, but end up back on Earth. For Star, this means she will be separated from Marco forever. She goes to the Realm of Magic to destroy it, albeit with a good level of reluctance. After the deed is done, Star couldn't bear to be separated from Marco and tells her mother she will take the well to Earth before it closes, and jumps in to be with Marco one last time.
  • Acceptance: When the process completed, the well sends Star back to Mewni. Star reunites with her mother, having come to terms with everything that led to that moment. She accepts that her mother did make a mistake, it wasn't completely out of ill-intent, yet bad things will always happen even then. Star looks to Eclipsa as an example, mentioning that all she did was fall in love and she received far worse treatment than Star gave Moon.
• Foil: The series highlights her and Marco's different reactions to the thought of having feelings for the other: while Star's feelings have been building up the more she was drilled despite saying otherwise, Marco remained indifferent to the possibility, not thinking anything would come of it. When it came to Star admitting she has a crush on Marco, Star attempts to avoid acting on it further, while Marco moves on and doesn't make a big deal about it... for a time.
• Foreign Exchange Student: How Star's passed off at Echo Creek Academy. She's certainly "foreign" all right.
• Forgot About Her Powers: Inverted, Star is or was very dependent on her magic, so much so that she forgot the fact that she was kicking arse and taking names well before receiving the wand. This is best shown in "Marco Grows a Beard" where she only learns this after having a dream about one of the laser puppies reminding her about her love of bare-knuckle fighting.
• Former Bigot: Star started off the series having a very skewed view towards monsters, being that they're all evil. A part of her character arc is dropping these biases. By the series finale, Star has made friends with monsters as well as becoming a supporter of the species.
• Friend to All Children: Star has shown a friendly, playful, soft side whenever she is near babies and/or small children.
• Friend to All Living Things: Downplayed. Most of Star's magic includes cute and cuddly creatures, suggesting she has a soft for animals.
• Fun Personified: Star is the living embodiment of fun.
• Genius Ditz: Toes the line between this and Brilliant, but Lazy. Glossaryck mentions that none of Star's spells are in his spellbook, so all of her unique spells are things she came up with on instinct. At the same time, she knows next to nothing about magic and routinely flops at getting her magic to do what she wants outside of combat. She also once nearly erased the multiverse to avoid doing a math problem.
• Genki Girl: Star is usually full of energy and excitedly examines her surroundings while waving hello to strangers. In season 2 she developed a love for sugar and becomes far more energetic.
• Girlish Pigtails:
  • "School Spirit" showed that she had these when she was a toddler.
  • Her hair is styled in braided pigtails in her Mewberty form and when she's in her Golden Super Mode.
• Girly Bruiser: Star wears lots of different dresses, likes adorable creatures, and is very good at beating up monsters.
• Girly Girl with a Tomboy Streak: She loves anything cute, wears a plethora of different dresses, and tends to blast very cutesy (but dangerous) rays from her wand... but she also really enjoys fighting monsters and going on adventures.
• Glass Cannon: Downplayed. She's very capable of fighting even without the wand, but the wand is her primary source of major offensive firepower, so against tougher enemies she can sometimes get into trouble if she's attacked directly (or worse, if she loses the wand).
• Golden Super Mode: During the climax of The Battle for Mewni, Star reclaims the remnants of the Realm of Magic not tainted by Toffee, purifying Toffee's corruption. When she emerges from the void, she takes on a gold and white mewberty form similar to her mother's. She then fires a golden beam of magic that disintegrates Toffee. Later, she gains the ability to use this form at will after visiting the Realm of Magic a second time. It's so powerful it's one of the very few things capable of fighting on par with Meteora.
• Gone Horribly Right: Star's tried to be a matchmaker for Marco so he can go into a relationship with Jackie. She was successful in pairing Marco and Jackie but develops a complicated crush on him and only seems to slightly realise it after seeing him with Jackie.
• Gorgeous Garment Generation: She can use her wand to conjure new outfits out of nothing, usually either to act as disguises or just to look really cool.
• Gratuitous Princess: Star is the princess of another world. Her best friend, Pony Head, is a princess as well. To some extent, this trope is defied due to the Destructive Saviour nature of Star.
• Hair of Gold, Heart of Gold: Has blonde hair, and so far all the messes she's caused were magical accidents from trying to help others.
• Heartbroken Badass: She developed a crush on Marco but became heartbroken after she gave him enough confidence to become a couple with Jackie. He only caught onto her crush on him when it was spelt out to him and confirmed by Star.
• Heroic BSoD: Happened twice so far.
  • "St Olga's Reform School For Wayward Princesses": When Marco is captured and she can't seem to break Pony Head free from her brainwashed state, making her feel powerless to do anything. Attacking a poster manages to snap Pony Head back to normal who convinces her to keep going.
  • "Marco Grows A Beard": When she felt she couldn't continue on without her wand. During a nap, her subconscious takes the form of one of the Laser Puppies to convince her she was already tough without the wand and didn't need it for everything (which ironically is what Marco was trying to tell her earlier).
• The Heroine: The series revolves around Star's adventures in defeating the forces of evil while learning how to properly use her magical wand.
• The Hero's Journey: Star goes through one in the first and second seasons. Finishing in the first half of the third season:
  • Miraculous or unusual circumstances around the Hero's conception or birth: Star displays a strong ability with magic, somehow being able to compose her own spells. According to Baby, only Eclipsa has ever been able to do this.
  • Begins in the ordinary world of the Hero's hometown: The story starts with Star being her usual Blood Knight self in the magical kingdom of Mewni, looking for fights with the monsters.
  • The Herald brings a Call to Adventure: She inherits the wand from her mother and is shown to be dangerously inept with it.
  • Crossing the First Threshold: Out of fear for the kingdom's safety, her parents send her to another dimension so she can learn and improve with her magic.
  • The Land of Adventure: Despite some initial misunderstandings, Star does make Earth her home until she learns how to master her magic. She befriends Marco Diaz and makes some other friends along the way, as well as meet Glossaryck, who guides her on how to use magic.
  • The Spiritual Death and Rebirth: Star starts going through emotional complications. She starts learning about the true history of her kingdom. Toffee also becomes the main villain of this part of the story and is shown to be significantly different from Star's usual enemies. Through Toffee and this discovery, Star starts to mature.
  • Road of Trials: Star starts taking steps to improve the relations between Mewman and monsters while also starting to fear Toffee. She starts by befriending her former enemy Buff Frog and when Toffee starts to reemerge, Moon evacuates Star from Earth.
  • Night Sea Voyage: Star and Moon start finding a way to defeat Toffee, they first try to resurrect the Commission and when this doesn't work, Star resorts to finding Buff Frog.
  • Time out just before the big battle: Star starts composing a plan to defeat Toffee and she does make her way back to the kingdom. Only to find out that Ludo has taken over and has seemingly executed her father. She also reunites with Marco and the pair have a heartfelt reunion.
  • Fight against the Big Bad / Apotheosis: Star returns to battle and discovers that Toffee has been using the wand fragment to control Ludo. She convinces Ludo to let her help him and uses the Whispering Spell to de-power his wand, simultaneously transporting herself to the Realm of Magic to confront Toffee. She discovers that Toffee has been corrupting the Realm of Magic and using the magic drain to weaken his enemies. Toffee tricks Moon into releasing him and he promptly traps Star in the Realm of Magic by shattering the wand crystal. She does eventually escape from the Realm of Magic by absorbing the last bits of untainted magic and transports herself back to Mewni. She promptly disintegrates Toffee and he's finished off by Ludo. Putting an end to Toffee, seemingly, once and for all.
  • Crossing the Return Threshold: With Toffee defeated and Star now having mastered her magic. Star can now stay in Mewni.
• Hero with Bad Publicity: In seasons 1 and 2 the citizens of Mewni mainly remember Star as the princess that set fire to the kingdom. Her reputation starts to get better in season 3 after she settles down and starts to finally take her royal responsibilities seriously, only for all that good will to go down the drain when she decides to Abdicate the Throne to Eclipsa.
• Heterosexual Life-Partners: With Pony Head; "Freeze Day" shows that the two have been friends since they were toddlers.
• Hidden Depths:
  • In "Diaz Family Vacation", in a few seconds she manages to make a fairly detailed unicorn head paper cutting, possibly indicating that she has a talent for making paper cuttings.
  • "Wand to Wand" shows that she enjoys building model ships in bottles.
  • In "Lint Catcher", she sings about how much she enjoys her burrito. She's good at singing (she sung the outro song but this is her officially singing in the series).
• Hormone-Addled Teenager: Downplayed. Star is the protagonist of the show and has development separate from her love life, but she is also boy-crazy (especially in season 1) and gets excited at the chance of seeing 30-year-old Marco's Hunk body.
• Horse Archer: She's able to fight on horseback by using her wand to cast spells.
• Horseback Heroism: Star is a skilled equestrian. She tames wild unicorns, favours the warnicorn stampede spell and planned to be horsekeeper who raised warnicorns. She's also capable of combat on horseback.
• How Do I Shot Web?: Star doesn't fully understand how to operate her magic wand yet. She's mostly OK in combat with it, though.
• Human Alien: Star looks human, but she's an alien princess from another dimension. The alien aspect is emphasized in the episode "Mewberty". The Magic Book of Spells reveals that she also has some demon blood from her great-great-great grandfather, Lord John Roachley. Marco's interpretation of the ancient inscriptions in "Mama Star" strongly implies that Star and the rest of the Mewman species are humans after all, just after centuries of magic-based mutations (and occasional interbreeding with non-humans).
• Humanity Is Infectious: In the beginning she was reckless with her magic, a lover of violence and had strong, prejudiced views on monsters. Through her time on Earth with Marco she started using her magic responsibly, using her words rather than violence and started being an advocate for monster equality. If she didn't come to Earth then she would have repeated the history of her ancestors.
• I Am Not My Mother: She refuses to rule Mewni in the same manner as her mother and when she realizes that she has to be queen regardless of her choice, she tries to ruin her chances until Marco calms her down and tells her that she can make her own choices when ruling.
• I Am Who?: She does not take the news of being a Pie Folk well.
• I Don't Want to Ruin Our Friendship: Star couldn't admit to Marco that she had a crush on him because she knew he didn't feel the same way, and she didn't want to lose him as a friend.
• I Just Want to Be Normal: Notable only in that Star tends to flip flop between this and I Just Want to Be Special for various reasons. In this case, Star's been shown on several occasions to be terrified of one day becoming Queen, and all that it involves because she'll have to give up the endless freedom she's grown used to her whole life in exchange for ruling. What Star seems to want over all is to be more normal than someone from Mewni, but more special than someone from Earth, while either society seems bent on tugging her one way or the other.
• Idiot Ball: Star tends to have this bad habits. However, her biggest idiot ball was that she focus on wanting a normal life and keeping an eye on Ecplisa that she failed to keep an eye on the Magic High Commission instead. By not checking on the Magic High Commission, they were able to come up with a plan to overthrow Ecplisa and put everyone in Mewni endanger.
• Imagination-Based Superpower: In "The Hard Way", Glossaryck reveals that most of Star's spells aren't really spells at all. Star is just using her imagination to make stuff up and her wand makes it real.
• Inept Mage: So inept, in fact, she was shipped off to Earth before she caused any more natural disasters from her inability to gauge what she's capable of actually pulling off with that wand. Most of the time she actually does get the effect she wants from her spells, the problem being that they're way more powerful than intended and thus cause massive collateral damage. Outside of battle when she's not trying to blow anything up or set anything on fire... she frequently does so anyway.
• Innocent Blue Eyes: Symbolizing her youthfulness, friendliness, and naivete.
• Interspecies Romance:
  • Downplayed, Star was in a previous relationship with Tom, a half-demon and half-Mewman. Star herself is also part demon, as her great-great-great grandfather was one.
  • She's crushing on Oskar Greason, a human. And eventually, she develops a crush on Marco.
• Insistent Terminology: After Moon disappears while fighting Meteora, Star is forced to take her place. However, she continuously reminds others that she is acting queen when they refer to her as Queen Star.
• It Runs in the Family: Star comes from two families of gifted people. Her magical powers come from her mother's side, while her strength, toughness, and passion for combat comes from her father's.
• It Was a Gift:
  • The wand was bestowed upon her on her fourteenth birthday.
  • Her horned headband was given to her by her ex-boyfriend Tom.
• I Want My Beloved to Be Happy: Deconstructed. Star is trying to invoke this by being a Shipper on Deck but leaves herself no outlet to deal with her own feelings and is just stuffing them down.
• Jerkass Ball:
  • In "The Other Exchange Student", Star comes off rather selfish. Granted, she does have some reason to be suspicious of Gustav after the first meeting and she's sorta right, but her initial reaction to him seems rather hostile. Somewhat justified, as she is a princess and the only child of her parents.
  • "Booth Buddies" has Star dragging Marco into taking photos in the old photo booth due to Star reminiscing their old taken photos. She even takes Marco's money to pay for them without asking. Star even forces him into remaking their poses from their old photos.
• Jerk with a Heart of Gold: Even though she's reckless and tends to be a bit pigheaded, she means well and does what she can for her friends and family.
• Just Friends: "Sleepover" and "Naysaya" show that Marco is not lying about his crush on Jackie and that he only sees Star as a "great friend". Star, on the other hand, has developed genuine feelings for him. Even Star herself is aware of this when she gives her Anguished Declaration of Love to Marco in "Starcrushed".
• Kamehame Hadoken: One of Star's new abilities in Season 4 is this, which involves blasting a heart from her cupped hands.
• Karma Houdini:
  • Many episodes seem to work in her favor despite her recklessness causing accident after accident.
  • Despite outright cheating on Tom with Marco, Star never received any comeuppance or call outs for it.
• Kicking Ass in All Her Finery: Wears a fancy dress in her intro while sliding down railings, beating up monsters, and then taming a wild unicorn.
• Kiddie Kid: Star is a 14-year-old with the mindset of a 7-year-old. Her spells are rather child-like too. She is certainly impulsive and often doesn't think her ideas through.
• Kid Has a Point:
  • Star calls out Moon in "Starcrushed" for making decisions about her life without talking to her, whether it was coming to Earth or going back to Mewni.
  • When Eclipsa returns in "Stranger Danger", Star makes a number of accurate points in regards to Eclipsa and whether she deserves punishment. First, while it may have been selfish to abandon her kingdom, the fact that the Magic High Council and Moon want to imprison without evidence or a trial is unfair. Second, Star sarcastically calls out her mother that it was ultimately her choice to ask Eclipsa about the spell to destroy Toffee, and Eclipsa didn't force or trick her. Third, while she blatantly tells Eclipsa she doesn't trust her, the former Queen should still be treated fairly.
  • In "Butterfly Trap", Star rightfully admonishes the Magic High Council and their hypocrisy for wanting others to follow the rules they set but refuse to do the same.
  • When Eclipsa tries to force her way to setting Globgor free by taking over Rhombulus' body in "Swim Suit", Star correctly states that if she does such a dubious and morally wrong action, then no one (Star included) would be able to trust her.
• Kung-Fu Wizard: Star is a lot better at physically fighting than magic, though she is decent with combat magic. Any other time, she is very much an Inept Mage.
• Leg Focus: Marco seems to think she has decent legs.
• Light 'em Up: Star can generate light from her wand, and has also used spells that produce sunshine and rainbows. This ability is even prominent in the opening theme.
  • She has a tendency to weaponize rainbows, such as with the "Rainbow Fist Punch" and "Rainbow Flytrap" spells. Some of her rainbows also have an unfortunate habit of catching on fire.
  • She also created the laser puppies, which appear in the outro.
  • In "Sleep Spells", she uses the "Mega Explosive Crystal Laser"... which is just a laser pointer.
  • In Battle for Mewni it's revealed that magic takes the form of a golden liquid, which she tries to desperately recover. When she does, she goes through an angelic transformation sequence and blasts Toffee with a searing, unforgiving sunlight.
• Light Is Good: She tends to associate with light, such as in her name and abilities, and for the most part is a friendly, heroic individual. This goes one step further at the end of Battle for Mewni, when she acquires a golden angelic form and blasts Toffee with a Holy Hand Grenade, apparently a decent alternative to Eclipsa's dark spell.
• Like a Daughter to Me: Has this bond with Eclipsa, since Star has a troubled relationship with Moon and Eclipsa's daughter is missing. And even after the reveal that they aren't related, Eclipsa still thinks of Star as her (grand)daughter and the latter reciprocates.
• Like Parent, Like Child: Star got her monster-fighting prowess from her father.
• Limit Break: She gains one in "By the Book" in the form of her Warnicorn Stampede spell. On one hand, it requires an entire kata before the spell cast. On the other hand, this is the result.
• Limited Wardrobe: Averted. She wears a variety of casual outfits throughout the show.
• Literal-Minded: She often takes figures of speech literally, like responding to "Wouldn't you like to know?" with "Yes, that's why I asked." And when asked what she sees in an inkblot test, she says "An inkblot! I win!"
• Little Miss Badass: Star has been kicking monster butt for a long time, even before she received her magic wand.
• Long Hair Is Feminine: She has really long golden hair and is very much a Girly Girl.
• Loss of Identity: The revelation that all of Star's ancestors up to Festivia are not blood to Queen Eclipsa, but an illegitimate line imposed by the High Commission to keep Eclipsa's monster-Mewman hybrid daughter from the throne shakes Star to the core.
• Magical Girl: Her backstory has elements of the original definition of "magical girl", being a princess of a magical kingdom in another dimension who's sent to live on Earth. Instead of having to pass a Magical Girl Queenliness Test, it's because she nearly destroys her kingdom shortly after getting her Magic Wand. She also has more modern elements of the trope, like how her Golden Super Mode has a Transformation Sequence that looks like it came straight from Sailor Moon.
• Magical Girlfriend: Her relationship with Marco pretty much epitomizes the core of how this plot device works: Star is the magical princess from another dimension who suddenly changes Marco's boring life when she moves in with him and starts dragging him into her adventures. However, Marco wasn't exactly enthusiastic when Star first entered his life (just the opposite actually), but gradually came to warm up to her.
• Magical Girl Queenliness Test: Parodied; Star is sent to Earth precisely because she's proven she can't handle the inherited wand very well. This is more for her education than anything. Once she loses Glossaryck, her mom had to resort to calling in Baby as an alternative means of evaluating her. After defeating Toffee, Star has proved herself worthy to return to Mewni, and can finally move on to the next chapter as future Queen of Mewni.
• Magical Girl Warrior: Star uses her magic wand to fight evil, even though she doesn't completely understand it. She can even fight reasonably well without her wand.
• Magic Is Evil: Played With. Star decides that using magic to solve problems only causes more problems, and the ones using it are all idiots who don't deserve the power they have, her own family included, and the cause of all problems by the end of the series. It's seen as a good thing when Star decides to destroy magic because it cannot be used responsibly, and it causes more problems than it solves.
• Magnetic Hero: Despite only being on Earth for a short time, Star manages to win over Marco's parents and her entire school (sans Brittney).
• The Maker: The unicorns living in the Realm of Magic see her as this, since she triggered the rebirth of their dimension after it was destroyed by Toffee. In "Mama Star" she calls The First One her daughter.
• Manic Pixie Dream Girl: Deconstructed. While Star does make Marco's life more interesting, the show is more about her growing as a character by toning down her chaotic overenthusiasm by being with the safety-minded, levelheaded Marco.
• Marked Change: When Star taps into her true power, her Facial Markings glow.
• Mark of the Supernatural: The only outward physical difference between the Mewman Star and all the humans is she has heart-shaped markings on her cheeks.
• Matchmaker Crush: Attempts to set up Marco with Jackie, but ends up developing a crush on Marco.
• The Missus and the Ex: Despite Marco and Star only being friends, Marco and Tom have this dynamic in "Mr. Candle Cares". They started getting along because Marco and Tom talked about how Star always changes the rules so that she can win.
• Mike Nelson, Destroyer of Worlds: Star is very nice, but the reason she was sent to Earth was because she set fire to her own kingdom.
• Mook Maker: Can turn ordinary animals into grotesque and powerful versions of themselves.
• Morality Pet:
  • To her best friend of Mewni, Princess Pony Head, as Star is the only person that Pony Head is never mean or obnoxious to, at least intentionally.
  • To Tom especially after they start dating again, and Star reminds Tom the best way to better himself as a person.
• Mythical Motifs: Whether this is intentional or not is up to debate, Star has a lot of similarities to Loki from Norse Mythology.
  • In Norse Mythology, Loki was a god who overcame problems through cunning and in modern tellings, Loki is depicted as morally superior to the Aesir, who are depicted as corrupt and immoral. In the myths, he was Odin's blood brother and the mother of the eight-legged horse Sleipnir. The format of Loki's myths is that he's blamed for something and the gods force Loki to fix it for them. In the Ragnarok prophecy, Loki is against the gods by siding with his children as they bring about the end of the world.
  • In the series, Star is a mewman of noble birth who overcame problems by using magic haphazardly. When Star learns of Mewni's history, she becomes morally superior to the Butterfly family, who annexed the monsters and attempted a race war multiple times. Due to being part of this family, the monsters hold her and her family accountable for the actions of their ancestors and the mewmans force the Butterfly queens to do everything for them. In the end, Star turns against the mewmans as she and her friends and family trigger armageddon through the destruction of magic.
    • Like Loki, Star has connections to Scandinavia. Loki is a Norse god and Star is a Johansen on her father's side. The Johansens are a barbarian clan based on Nordic clans and royalty.
    • Like the Norse gods, the mewmans force the Butterflys to solve a problem they can't handle, the Butterflys gives them a scapegoat so they can maintain their own perceived flawlessness as a species, and the mewmans are never introspective enough to meaningfully improve their lives or take responsibility for themselves.
    • In the series, Star is characterised as the rebel of the Butterfly family because she refuses to follow the traditional role of a princess. In Norse mythology, Loki is a magic user and he doesn't act like a traditional Asgardian.
    • In the series, it's revealed that all descendants from Festivia are an offshoot from the original Butterfly bloodline. After learning this, Star still occupies the castle in order to help Eclipsa with the public image. In Norse mythology, Loki and Odin were blood brothers but Loki is also theorised to be an offshoot of Odin due to their associations with trickery. Loki hangs around Asgard and often helps the Asgardians with their adventures. In recent studies by Eldar Heide in his work ”Loki, the Vätte, and the Ash Lad: A Study Combining Old Scandinavian and Late Material.”, Loki may not have originated as an Asgardian. Like how Star isn't a member of the original Butterfly clan.
    • In the series, Star is the mother of a horse-like monster called "The Firstborn". In the mythology, Loki is the mother of the eight-legged horse Sleipnir.
    • Like Loki, Star ends an imperfect world to make way for a new one. In Norse mythology, Ragnarok is theorised to have been originally framed as a cleansing armageddon, an event that destroys the world but allows it to be rebuilt as something better because the gods were too corrupt, destructive, and immoral. In the series, Star destroying all the magic is framed as ultimately a good thing because magic is way too dangerous to be used responsibly by anyone. The mewmans used magic to oppress others and fuel a monster genocide.
    • Like modern tellings of Loki, Star is considered to be morally superior because she learned the dark history of her family and decided to improve the relationship between humans and monsters.
• Never My Fault: Star solely blames Ruberiot for her Song Day disaster, claiming he's good at "ruining people's lives with songs", even though she was the one who willfully gave him the information to write the song that revealed her crush on Marco and the fact that she had lost Glossaryck and the Book of Spells.
• New Transfer Student: How she is introduced in the first episode and is the main reason she and Marco met because she was new to the school (and Earth in general) and needed a guide.
• Nice Job Breaking It, Hero: In "Bon Bon the Birthday Clown" Star's jealousy causes her wand to malfunction at the worst possible time, forcing Marco to abandon his efforts to retrieve the magic book from Ludo and go rescue Star. On a more minor note, Star's jealousy at seeing Marco and Jackie riding a skateboard together is what causes them to crash... and that crash is what leads to their first kiss.
• Nom de Mom: Star's last name comes from her mother, which implies that the Queen is the actual ruler while River is a King Consort.
• Not Herself: In Season 3, Star keeps dropping the statement that she wants to focus on being a better princess to explain her current situation. It would sound like much-needed Character Development, but not only is it not like her to do so, it's almost too convenient that she's said it in rather awkward situations (i.e. having to dance with Tom, Marco suddenly returning). If her conversation with Eclipsa in "Lint Catcher" is of any indication, Star is undoubtedly hiding something and avoiding it.
• Official Couple: With Tom and, eventually, with Marco.
• Once Done, Never Forgotten: Ruberiot's song will never leave Star. Especially the stanza where it goes into a mortifying description of her crush on Marco. Because of this, everyone in the kingdom already believes they're dating, from Tom to even the squires.
• O.O.C. Is Serious Business:
  • When Marco is captured in "Storm the Castle" she loses her usual Blood Knight attitude and settles into Tranquil Fury.
  • A combination of losing her family's spell book and seeing Marco with Jackie leads the cheerful Star crying.
  • Star, who was the number one supporter for Eclipsa's innocence has the latter imprisoned because she indirectly led to her mother's disappearance.
• Oral Fixation: Star has a tendency to nibble on her wand whenever she gets particularly excited.
• Parental Title Characterization: Star usually refers to her parents as "mom and dad", but whenever she is truly scared, she will often refer to her parents as "mommy" and "daddy".
• Perky Goth: Star's wardrobe seems to be a mish-mash of cutesy, bright colors and spiked accessories. She always sports a hairband with devil horns, owns a pair of military boots with a horn sticking up from the toe of each, and wears a spiked bracelet. And has a mace.
• Playing Card Motifs: Star has heart-shaped markings; her mother has diamond-shaped markings, her implied Long-Lost Relative Miss Heinous has club-shaped ones and her ancestor Eclipsa had spade-shaped ones.
• Plucky Girl: Being a goofy, zany, individualistic, free spirited and unrestrained wild child with a big heart and even wilder imagination than most princesses you'll ever meet, Star is the epiphany of joy and excitement given form.
• Politically Incorrect Hero: She starts out as a Fantastic Racist, believing monsters to be Always Chaotic Evil. However, throughout the course of the seasons, she eventually drops her previous racist beliefs of Monsters and is now taking steps to improve relationships between Monsters and Mewmans.
• The Pollyanna: Star is very optimistic.
• Power Floats: When she learns how to "dip down" and cast spells without the Wand in "My New Wand!", Star floats into the air and her whole body glows a deep blue.
• Power Gives You Wings: Star's Mewberty form has a pair of large golden butterfly-like wings.
• Power Incontinence: Her main issue; she's quite spell-happy on her own merits, but she's extremely bad at avoiding unintentional aspects to her creations (rainbows that set themselves on fire are a big thing with her).
• Power Limiter: At the end of the day, her wand was really meant to only help her channel and focus her magic and spells, as Moon stated. It's even stated by Baby that Star could be more powerful than what she's observed.
• Pretty Princess Powerhouse: A princess in a nice dress with a big pink heart on it, and Star knows how to fight without the wand, either fighting physically or using a weapon, like a mace.
• Princesses Prefer Pink: Downplayed, while she may like the color pink well enough, her wardrobe consists of the entire rainbow, and prefers a sea green dress for everyday use.
• Proper Tights with a Skirt: In eight of her outfits (including non-recurring ones) she wears tights underneath her dress or skirt.
• Protagonist Title: Star vs. the Forces of Evil.
• Proud Warrior Race Girl: Star loves beating the snot out of monsters, and it would appear that many Mewnian virtues and traditions revolve around antagonizing them. One of the greatest lesson Star must learn to mature as a person is that there's a fine line between "Warriors" and "Thugs".
• Psychoactive Powers: "Wand to Wand" reveals that her new wand is affected by her emotions. If she's feeling angry or frustrated, the spells she cast won't work right. But if she feels more positive emotions (like concern for Marco), her spells will work the way she wants them to.
• Psychological Projection: The way Star specifically singles out her mother out of everyone after finding out she helped Mina raise the Solarian Army and escaping Mina carries an element of projection to it, even if those accusations are justified. Star accuses Moon of starting a revolution behind her back to making Mewni more dangerous, and then blames everyone who uses magic and calls them idiots. However, Star herself throughout the season made questionable decisions and kept both Moon and Eclipsa in the dark about it, and a great number of her decisions to better Mewni turned out more disasterous than she anticipated and refused to admit it, and then there's the fact that Star herself recklessly used magic.
• Raised by Dudes: In a sense. The Mewni's Royal Guards were her babysitters.
• Randomly Gifted: Star rivals Eclipsa for the greatest magic potential in the Mewni royal line, apparently just by random variance, which is made doubly coincidental by the revelation that Star and Eclipsa aren't even related.
• Read the Freaking Manual: A constant issue with Star, as many of the issues of the show could be solved much quicker if Star read her wand's manual before rather than after she had started blasting. The fact that it's a completely disorganized mess with a living glossary named Glossaryck (who isn't very helpful) doesn't make reading it easy though.
• Rebellious Princess: Star is not thrilled at the idea of being a "well-behaved princess" and does everything in her power to rebel against it. She's even explicitly referred to as a "rebel princess" in the episode "Raid the Cave". In Season 3, she's not being rebellious for the sake of it. She's realized that, for centuries, her family cruelly treated monsters like they were abominations. She wants to change that and put an end to their prejudice.
• Red Oni, Blue Oni:
  • With her boyfriend Tom, as he is more connected to voicing his anger. whereas Star is more collected about her thoughts and actions. In "Monster Bash", Star was the one that was trying to take a logical approach to handling the Mewman and Monster prejudices whereas Tom was more emotional by trying to spend time with Star. Extra points go to their respective kingdoms, Mewni is blue whereas the underworld is red.
  • With Marco, she is the energetic and wild Red Oni and he is the safety-minded and level-headed Blue Oni.
• Relationship Upgrade:
  • Star broke up with Tom in the past because of his anger issues (among other things). As of Season 3's "Lava Lake Beach", after Tom's Character Development, they've decided to give things another chance and gotten back together again.
  • As of Season 4's "Here to Help", Star and Marco are officially a couple, after several seasons' worth of Ship Tease.
• Rich Kid Turned Social Activist: Star Butterfly, princess of Mewni's royal family and heir to the throne, becomes a proponent for the rights of monsters by the second season after re-reading her Mewnipendence day book revealed how unfair the Mewman treatment of monsters really was.
• Royal Brat: When she was younger, she would pull a lot of mean pranks on her servants, such as putting Noxy Frogs in their beds on her 10th birthday.
• Sacrificed Basic Skill for Awesome Training: For some (as of now) unexplained reason, Star can't do basic magic, all the spells she casts are advanced.
• Scylla and Charybdis: Her pursuit of monster equality hasn't been as simple as she wanted it. She discovered that she's part of a line of ancestors who were imposed by the High Commission to keep Eclipsa's monster-Mewman hybrid daughter from the throne. She's now stuck with a very difficult decision. If she maintains her role as Princess then she betrays her ideals, if she allows Meteora to take the throne then she loses her identity as a princess, and Meteora is clearly completely insane and unfit to lead. Fortunately for her, Eclipsa doesn't care about the throne as much as she just wants her daughter back, and after Meteora is magically regressed back into a baby, she wants to give her daughter another chance at growing up.
• Shamu Fu: One of her favorite spells is "Narwhal Blast", which drops living narwhals on her foes.
• She Cleans Up Nicely: While Star is generally not unpleasant at look at, she really spruces herself up for the Blood Moon Ball. When she's finished◊, Marco tells her she looks "amazing".
• Shipper on Deck:
  • Takes it upon herself to hook Marco up with Jackie when she learns of his crush on the girl. Though during "Sleepover", she attempted to push both Jackie's and Janna's faces towards Marco's. And then she develops feelings for him. Oops.
  • She gives a romantic "aww" sound when she sees a hologram of Eclipsa with her monster husband, Globgor.
• Signature Headgear: She wears a headband with little horns on it; according to the Magic Book of Spells, they're a souvenir from her first date with Tom. In "Freeze Day" she swaps it out for a green one with little cactuses.
• Signature Move: Star's favorite spells are the following: Spider with a Top Hat, Narwhal Blast, and Rainbow Fist.
• Significant Birth Date: Star was born on Stump Day; however, she does not celebrate it that day as it would anger the Stump.
• Single Woman Seeks Good Man:
  • Star has subconsciously developed a crush on Marco. Considering how good a dude he is, it's unsurprising.
  • In season 3, she gets back together with Tom, after the latter shows better control over his temper and is trying to become a better prince after being inspired by Star's attempts to be a better princess.
• Sins of Our Fathers: Star is a descendant of a peasant who was placed on the throne to hide Meteora for being a monster hybrid. Star is in deep trouble with Meteora who (understandably) wants to take her rightful place on the throne. Not only that but Star is dedicated to solving the monster-Mewman prejudice which was caused by both the original Butterfly family and Star's ancestors.
• Sitcom Arch-Nemesis: Unwittingly this to Brittney.
• Smitten Teenage Girl: Given her age and boy-craziness, Star can become quite smitten when she gains a crush on someone.
• Spanner in the Works:
  • Is this to Toffee's plan along with Ludo. Toffee had hoped to ransom her in exchange for his finger, which would fully revive him complete with the magic power of Ludo's wand in his hand. But Star gets through to Ludo and performs the Whispering Spell on his wand, destroying it and being pulled into the Realm of Magic along with Toffee. So while Toffee still ransoms her for his finger and is resurrected, it is without magic power, and thus Star is able to defeat him when she achieves her Super Mode.
  • She also served as this for the Magic High Commission. Star and her ancestors' eligibility for the throne of Mewni was the result of the MHC's meddling and "erasing" Meteora, the rightful heir, from the line of inheritance, all because she was half-monster. But if it had not been for Star's actions, Eclipsa would've remained imprisoned, which had a lot of influence in unearthing the Government Conspiracy.
• Stepford Smiler: Remarkably good at it. In "Just Friends", Star goes to the Love Sentence concert with Marco and Jackie, surrounded by couples, Marco and Jackie kiss, and Star leaves, but she never stops smiling. Then she blows up the concert sign with green magic, which is powered by negative emotions.
• Stellar Name: Her name is Star.
• Strong Family Resemblance: Star looks exactly like her mother in her youth, save for the different hair color and Facial Markings.
• Summon Magic: Can summon narwhals, dragons, snakes, and other creatures as allies or to supplement her Frickin' Laser Beams. Amusingly, while they do vanish on their own after the spell is cast, sometimes they stick around and have to crawl back to wherever they came from.
• Super-Cute Superpowers: Her combat spells blast enemies with rainbows, hearts, and jellybeans to devastating effect.
• Superior Successor: Queen Moon was a bit older than Star when she first "Dipped Down".
• Super Mode: She briefly turns into a bright yellow butterfly-human hybrid at the end of "The Battle for Mewni" and blasts Toffee with enough power to severely weaken him. Later she starts transforming in her sleep and creating portals to other dimensions. After she successfully reaches the Realm of Magic a second time she gains the ability to transform at will.
• Superpower Lottery: In a setting with all sorts of mythical monsters, magical creatures, and skilled fighters, Star outshines them all with her wand. With it, she can summon various beasts, create and alter massive constructs, unleash powerful energy blasts, and theoretically destroy the universe. The main thing holding her back from being a story-breaker is her lack of experience and discipline. Naturally, the villains tend to make the wand their primary objective. It's eventually revealed that Star has incredible magic power even without the wand, in addition to superhuman strength and durability.
• Super-Strength: Despite Star being a skinny, 14-year-old teenage girl, she's able to easily kick, punch, or simply overpower monsters that are more muscular and bigger than her. She also on occasion wields a mace or sword that's bigger than she is, with no apparent effort. Quite possibly, this is a trait she shares with her people.
• Surrounded by Idiots: Non-villainous example. In "Divide", she becomes increasingly agitated at her castle staff's complete inability to think for themselves, up to the point that the chefs don't know how to write a menu. Downplayed because it is implied that they are used to Moon micro-managing everything and they usually do just fine as long as they have clear directions.
• Taught by Experience: She can easily kick the butts of Ludo's henchmen around, because, prior to getting the family wand, she would spend her time fighting monsters (and taming wild unicorns).
• There Is No Kill Like Overkill: Star tends to spam various magical attacks at her enemies, most notably "Narwhal Blast" which fires large numbers of live narwhals at opponents. Perhaps the best example is how she dealt with Toffee. While her mother used a special spell provided by Eclipsa intended to kill immortal beings, Star just hit him with an attack so powerful it burned off most of his flesh and left him on the brink of death.
• Tomboy and Girly Girl:
  • While still girly in her own right, compared to her mother Star is the unladylike, hot-blooded, messy tomboy to Moon the proper, calm, and neat girly girl.
  • She is the girly girl to Janna's tomboy.
• Took a Level in Cynic: The events of Seasons 3 and 4 shake her faith in Mewni's authority figures and even magic itself, to the point that she decides that the best way to stop Mina and produce true equality between Mewmans and monsters is to destroy all magic in existence.
• Took a Level in Jerkass: Only during Season 2.
  • In "Starsitting", all Star wants to do is have fun with the Buff Frog's tadpoles she and Marco are babysitting, rather than following Buff Frog's instructions opposite Marco.
  • In "Girls Day Out", in a fit of bordom, she sets her free, much to Miss Skullnick's shock and chagrin. One example of where Star doesn't twice.
  • During "Face the Music", she's appalled of the fact she has to have her own written song that stretches the truth. When Ruberiot arrives, she leaves after asking him for tea. Returning, Ruberiot says he can't leave until he writes her song, and Star was threatening to leave again unless he leaves. When Marco pleads she do as he says, Star replies she doesn't want anything to do with him or the song he'll write. She even calls him out on his work.
  Star: I know my mom sent you here, but honestly, I am sorry, I can't help you. Princess songs are objectively awful. They are these trite little puff pieces about perfect little princesses with perfect little lives, and that's not me! And songstrels like you are part of the problem! Your music just puts pressure on future princesses to be perfect!
• Took a Level in Kindness: By the beginning of Season 3, her experiences on Earth have made Star much more empathetic and willing to talk things out instead of mindlessly rushing into battle. She also becomes the first royal in generations to recognize her family's horrific treatment of monsters and take steps to rectify relations between Mewmans and monsters, unlike her ancestors and parents. She is even willing to risk her life to free Ludo (her arch-enemy) of Toffee's control, which is what ultimately gives her the strength to beat Toffee.
• Touched by Vorlons: After returning from the Realm of Magic in "Toffee" Star starts to develop abilities that go beyond normal Mewman magic, including creating portals without dimensional scissors and going into her Super Mode without the years of training normally required to do so.
• Tragic Keepsake: Downplayed. When Star has to leave Earth, she keeps one of Marco's hoodies so she can remember him. Marco isn't dead but the two are close friends and being forced into hiding was a tragic moment for her.
• Training from Hell: Her father taught her how to survive in the wilderness for 11 days straight without food... or clothing.
• True Blue Femininity: Her princess dress is light blue and her casual wear is bluish-green.
• Truly Single Parent: Star is this to the First One, as she created her after triggering the rebirth of the Realm of Magic. Star even calls herself the First One's mother in "Mama Star".
• Tsundere: In "Battle for Mewni", Star watched Marco from her wand and spoke aggressively about him but still showed signs of her crush on him. The primary example being that she called him a "cute idiot".
• Unknowingly in Love: "Sleepover" reveals that Star has a crush on Marco, but also implies that she might be unaware of it. As of "Bon Bon the Birthday Clown", however, she seems to be more aware of her feelings.
• Unlimited Wardrobe: Downplayed; she has a few different outfits which she cycles through, and distinctly wears a new one every time a day passes in an episode. It's still only about four outfits, less than a real person would have, but more than the average cartoon character. Every other character in the show plays the trope straight, making her stand out even more.
• Unskilled, but Strong: Star won the Superpower Lottery with her wand, but starts out dangerously inexperienced. For this reason, she's sent to Earth in the first place. Even more so given she has the same potential as Eclipsa, but her lack of experience makes it clear Eclipsa is still way stronger.
• Unwitting Instigator of Doom: Her party at the monster temple in "Monster Bash" led Miss Heinous to Marco and to her true identity. From then on Meteora ended up losing the rest of her identity and leading an assault on St. Olga's. Which led to Pony Head getting her horn ripped off and then becoming the single, most powerful foe that Mewni has ever faced.
• Vocal Dissonance: Her voice sounds a bit more mature than how she looks and acts.
• Voice of the Legion: She gets a deep, reverberating voice in her Golden Super Mode. Though only the first time, subsequent times, she keeps her normal voice. The Book of Spells reveals that there are different levels of the form, and she never got the diamond eyes or yellow skin tone during any of the times she willingly entered this mode, suggesting the voice is connected to that version only.
• Wacky Parent, Serious Child: Inverted with Star and her mother, Moon. Star Butterfly is an adventurous and gung-ho girl who is a sharp contrast from her prim and proper mother. It's implied Star got it from her father. However, she's more serious than her father, who tends to embarrass her and do things even Star finds idiotic.
• Walking Disaster Area: The moment Star got her wand, she caused so much destuction on her homeworld that her parents decided to exile her to Earth until she learns how to use her magic safely and responsibly. A world probably far less prepared for that, but at least now it's not their problem anymore.
• Was It All a Lie?: The sincerity of Star and Tom's relationship was in a grey area for pretty much its entire run. It was implied that Star was initially using Tom to move on from her crush on Marco. Then it's eventually shown that Star still had some genuine feelings for Tom, after he showed her how much he's changed and how far he's willing to go to be a good person. Then "Booth Buddies" happens, and then "Lake House Fever" reveals that Star never intended to tell Tom about what happened in "Booth Buddies".
• "Well Done, Daughter!" Girl: "Sleep Spells" reveals that Star has issues regarding living up to the enormous pressure her mother puts on her to be the future Queen of Mewni. She often fluctuates between wanting to be nothing like her mother and desiring to be better than her.
• Well-Intentioned Extremist: Star wishes to put an end to the systemic racism against monsters and stop the Solarian Army from eradicating them. However, her plan to do so involves getting rid of ALL the magic from across the ENTIRE multiverse. Due to some characters' and species' reliance on magic to stay alive, this also kills a number of people across the multiverse, including members of the reoccuring cast.
• We Used to Be Friends: She and Rhombulus established a pretty strong friendship given their similar traits of rushing into things without thinking and not being taken seriously. However, their friendship diminishes when it's uncovered that he, along with the other Magical High Commission members, erased Meteora's existence from history. And after Eclipsa took over his body in an attempt to free Globgor, their relationship has become so bitter that they even have a physical fight. And needless to say when Rhombulus tried to frame Eclipsa and Globgor, putting innocents in danger, whatever good feelings she had for him is gone.
• What Does She See in Him?: Even Star herself admits can't find the reason why she dated Tom the first time around. When she began dating him again under the same circumstances that got them together the first time, it's different. Star at first wanted to get over her feelings for Marco, but began to fully appreciate Tom's attempts to be a better person for her, even though he was going to hurt himself for it. Tom even shows he cares by paying attention to important details like how to celebrate her birthday and is willing to admit when he's not a good boyfriend. That being said, Star really does enjoy Tom being around and she is happier with him than she was when they first dated.
• Why Did It Have to Be Snakes?:
  • Star's greatest fear is anything to do with St. Olga's Reform School for Wayward Princesses. The very name of the said school sends her into panic screaming.
  • She also has coulrophobia (a fear of clowns), as shown in "Cheer Up, Star" (though that might have just been because of the unintentionally creepy way that Marco went about with his clown routine). But by "Royal Pain", she seems to have gotten over it, since there was a clown creature in her room, and she didn't seem to mind it. By "Bon Bon the Birthday Clown" this fear has all but disappeared to the point where she's ready and willing to perform a dead clown seance.
• Windmill Crusader: Zig-Zagged in season 1. Star is from a dimension that's set in the medieval era and non-human beings exist. So when she comes to Earth, she misunderstands several concepts and believes that Earth is home to similar mystical elements. Sometimes, it's a case of believing in a place called "a better store" or believing that a magician is a vampiric being.
• Winged Humanoid: Grows insectoid wings when going through "mewberty", and she retains them (albeit in greatly reduced size, and without flight capability) after it's over. They're not really visible afterwards because her knee-length hair falls over them. In "Star on Wheels", she manages to get a small burst of flight out of them when she needs to pass over a sinkhole. In season 3, she's able to attain a full mewberty form like her mother, Queen Moon after purifying the Realm of Magic of Toffee's influence.
• Yin-Yang Bomb: Her tree spell from "Baby" glows both pink and green, implying that it uses a combination of both Star's light and dark magic.

Marco Ubaldo Diaz

"Frankly, I like taking risks. And would welcome a little danger in my life!"

Voiced by: Adam McArthur (English), Kazuyuki Okitsu (Japanese)

Older son of the Diaz family, and also a Karate student with a red belt. Shortly after meeting her, he becomes Star's earthly friend, guide, and combat partner.

---

• Action Survivor: He becomes this after surviving multiple dimensions for sixteen years.
• Almighty Janitor: Stripe or not, he's only a green belt (about halfway through the learning stages in martial arts). He's still kicked more monster ass than most people. The most badass green belt ever. Season two reveals that he has been a green belt for five years though not because of his skill level, but because his sensei is also only a green belt. At the end of "Red Belt", Marco is now a red belt.
• Amicable Exes: In "Sophomore Slump" Jackie gently breaks up with Marco because she believes that their relationship will sour overtime because Marco can't accept that he's left Mewni as well as Jackie believing that she's forcing Marco to stay on Earth to make her happy. When they meet up again in "Britta's Tacos", Marco is afraid that he was a horrible boyfriend to her, but she reassures him that he was a "standard boyfriend" and that they just didn't work. At the end of the episode, Jackie advises him to go after Star while Marco smiles at her and Chloe skating off together while holding hands.
• Anguished Declaration of Love: Marco reluctantly confesses his crush to Jackie during "Sleepover" in order to spare the group from the consequences of the Truth or Punishment game.
• Authority Equals Asskicking: In "Divide", Marco was in charge of the "Marc-nificent Seven". He was the founder and was Star and Mewni's (present) best warrior.
• Awesome Mc Cool Name: He sees his middle name as such.
• Badass Biker: While Marco spent sixteen years hunting Hekapoo, he gained a "dragon-cycle", a six pack and an epic beard.
• Badass Bookworm: Physically unimposing, fastidious A-student... who can karate-kick monsters three times his size and send them limping home.
• Badass Cape:
  • In "Running With Scissors", future Marco wears his hoodie as a cape, since he's long grown out of it. He also does this during his spar with Star in season 3.
  • Marco is gifted a cape from River after the Battle of Mewni, and constantly wears it when he returns to Earth. He stops wearing it after he learns that it's just a meat blanket, and that the honorary knighthood he was granted wasn't real either.
  • In "The Knight Shift", when Eclipsa confers a real knighthood on Marco, Star gives him a new hand-made cape with symbols representing some of their adventures together on the back. At the end of the episode, Marco returns the favor by making a similar cape for Star. When they sit together, those symbols combine to form a large heart.
• Badass Normal: Has no special powers and is good enough at karate to hold his own against Ludo's henchmen and other assorted monsters.
• Bare-Fisted Monk: Marco rarely uses weapons to fight his opponents, and uses his karate skills at every opportunity in combat (despite Star being the other half of the reason why the pair can win fights in the first place - when Star is preoccupied with the main villain or distracted by the events of the episode, Marco falls into an unfavourable position where he is either grappled or chased around the battlefield). Marco did eventually become a Combat Pragmatist and a Master Swordsman in "Running With Scissors" while pursuing and hunting Hekapoo, and still remembers these skills (albeit not at the same level without his muscular body).
• Battle Butler: Marco was initially tasked to be Star's guide to human culture, he also cooks nachos for her and himself and finally Marco and his parents also allow her to live with them. Marco is skilled at karate and is a Bare-Fisted Monk at his best but they are friends regardless. In season 3 he becomes her squire.
• Be Careful What You Wish For: Marco wanted a little more danger in his life and Star soon entered it, bringing a lot of that with her. He sarcastically quipped that if his family wanted some upbeat energy in their home, they could've just adopted a litter of puppies instead of letting Star live with them; she immediately summons some cute puppies... that fire lasers out of their eyes. When he admires the room she summoned and wishes he had one of his own, Star tries to give him one and creates a portal that sucks all his furniture instead.
• Best Friend: Marco is Star's best friend on Earth.
• Big Brother Instinct: After the birth of his new sister Mariposa, Marco wastes no time in becoming the most attentive, protective brother he can be.
• Big Ol' Eyebrows: In comparison to most of the people on the show. Just look at them!
• Blood Knight: Although he is calm, savvy, and safety conscious in most situations, Marco is also an avid martial artist who really likes fighting evil monsters, and thus sees Star's Fight Magnet life as a plus.
• Bodyguarding a Badass: Marco is responsible for Star's safety while she is on Earth, as he's her guide to Earth culture, and tries to get her out of trouble with the authorities when she makes a mistake. Marco also fights to protect her and the wand from Ludo and the other monsters when they become overwhelming or too powerful for her to handle. In season 2 he still has to fulfill some of his responsibilities from season 1 despite the hostile monsters having fewer appearances, because he still has to help Star keep control of her magic and fight off Ludo.
• Body Horror: In "Monster Arm", after he breaks his arm while practicing karate, Star attempts to fix it via magic. She instead transforms his arm into a giant tentacle, which turns out to have a mind of its own and be quite malevolent and destructive.
• Brainy Brunette: Dark brown hair + Only Sane Man + Good with Numbers + Cloudcuckoolander's Minder = A really intelligent kid.
• Butt-Monkey: His injuries and misfortunes are frequent and definitely Played for Laughs.
• Camp Straight: Downplayed. Marco may be In Touch with His Feminine Side (see trope below for more details), but he also has had a HUGE crush on the female Jackie-Lynn Thomas since they were children, and he is an avid martial artist with dreams of being a super-buff badass warrior and/or a knight, so while the show points these things out, he is clearly heterosexual.
• Cannot Spit It Out: With regards to his feeling on his crush, Jackie-Lynn Thomas. Marco has been crushing on her for years and he's still struggling to say something past "Hello" to her. As of "Sleepover", this is no longer the case anymore.
• Can't Stay Normal: When he returns from Hekapoo's dimension, he struggles to adjust from his high adrenaline lifestyle and has forgotten his computer's password. This is also shown in "Sophomore Slump", as a result of his adventures with Star and life on Mewni. Marco has very little in common with his Earth friends and Jackie eventually and gently breaks up with him because she fears that their relationship will sour overtime because Marco can't fully disconnect himself from Mewni no matter how hard he tries.
• Cape Swish: Does this at the end of the Season 3 intro.
• Character Catchphrase: A Big "WHAT?!".
• Charles Atlas Superpower:
  • He must be really good at karate, considering he can punch back one head from a massive Hydra!
  • He manages to karate chop Tom's hand off.
  • He LITERALLY punches a hole clean through Toffee's chest, which would've killed him if it weren't for his regenerative powers!
  • After spending sixteen years getting ripped in Hekapoo's dimension, he's strong enough that the wind from unsheathing his katana is strong enough to blow out a flame from about ten yards away.
• Chick Magnet:
  • In addition to heavy Ship Tease with Star Butterfly to the point that she has developed a crush on him, he's attracted the attention of Jackie, Janna has flirted with him quite a bit, Hekapoo shares some Foe Romance Subtext with him, and after Kelly breaks up with Tad for good, he has a bit of Ship Tease with her as well.
  • The "FanCo13 LIVE" chat held after "Starcrushed" aired also had StarFan13 calling Marco very handsome in his prince costume from "Face the Music".
• Childhood Friend Romance: Marco has been crushing on Jackie since kindergarten, but he gets so nervous around her that he hasn't made any progress with her in all those years. He finally asks her out in "Naysaya" and they start dating in "Bon Bon The Birthday Clown".
• Cloudcuckoolander's Minder: Was introduced to Star to act as her guide on Earth. "School Spirit" and "The Banagic Incident" illustrate just what happens when a flighty, hyperactive Fish out of Water armed with magic is left to her own devices.
• Clueless Chick-Magnet:
  • He gained attention from multiple women and doesn't notice. The best example of this being Star, as he only found out when Ruberiot spelt it out to him but even then, he was struggling to comprehend what happened until Star confirmed her feelings for him.
  • Star and Marco's Guide to Mastering Every Dimension shows that it's subverted as far as Janna is concerned, as he recognizes her teasing behavior as her flirting with him.
• Combat Pragmatist: Occasionally mixes up karate with utilizing his environment to fight, be it with boxes, a book, or a giraffe head.
• The Conscience: He's usually the one who keeps Star from causing too much trouble. In later seasons, she started getting the swing of things and making her own choices. He was this to The Seeing Eye spell, despite the spell not fully understanding the consequences of telling the truth.
• Control Freak: His reputation as the "Safe Kid" didn't come from nowhere. When he meets Star he's pulling her out of every minor obstacle (some understandable, some not). However, this gets zig-zagged, especially with regards to fighting, because he's also a Blood Knight; when he learns that Star has a price on her head he's absolutely thrilled at the prospect of fighting monsters.
• Cool Big Bro: Marco was ecstatic upon discovering he would become a big brother. And once his little sis is born, he is very loving, attentive, and protective of her.
• Cool Bike: Marco has a dragon cycle, as they've spent 16 years together it overlaps into Companion Cube territory as he affectionately calls her Nachos.
• The Corruption: Marco gets controlled by his new tentacle limb in "Monster Arm". It's implied that even after being cured, it still dwells inside him.
• Cowardly Lion: In season one Marco was safety oriented and would be the first of the co-protagonists to try to reason with the monsters, i.e. Lobster Claws and Princess Smooshy. Marco also refused to fight Lars out of fear until Monster Arm dealt with him. When he is in the middle of fight Marco can hold his own really well and enjoys every second of it when he's in a favourable position.
• Curtains Match the Window: Dark brown hair and brown eyes.
• Dark Is Not Evil: He is one of the protagonists and has several dark items associated with him. The blood moon and the wand's appearance in his ownership.
• Dashing Hispanic: Marco is half-Hispanic and is the heroic deuteragonist of the series.
• Deadpan Snarker: Exhibits a dry sense of humor.
• Deuteragonist: The second main focus character after Star.
• Disguised in Drag: In "St. Olga's School for Wayward Princesses", Star disguises him as a princess with a poofy pink ballgown and long hair and they join in with a group of new arrival princesses. Despite initially griping that he wanted to impersonate one of the guards, by the end he asks to keep the dress.
• Does Not Like Spam: Enforced. Thanks to Janna's off-screen hypnotism, Marco now dislikes nachos, which was his favorite thing to eat. Now, every time he thinks of nachos, he feels the urge to vomit.
• Dork Knight: Marco practically gushes after he and Star defeat Ludo and his men.
• Dude, Where's My Respect?: In the earlier seasons, Marco wasn't as popular as he wanted to be. He was frequently unlucky and the receiver of Star's magic despite his skills in karate and overall likability.
• Eagle Land: Marco chants, "USA! USA!" in celebration when he thinks he successfully grew out a beard, which is a pretty uniquely American thing to do.
• Embarrassing Initials: A test paper in "Match Maker" reveals his middle name is Ubaldo, which makes his initials spell out "MUD".
• Embarrassing Ringtone: His "Space Unicorn" ringtone which he claims is supposed to be ironic.
• Extremely Protective Child: Marco is very protective of his parents, as evident by him attacking Miss Heinous when he believes that she harmed them in some way.
• Famed In-Story: Marco has a reputation in Mewni. At St. Olgas he's a liberator under the name of "Princess Turdina", and the inventor of the "Sword Hand Dance".
• Fire-Forged Friends: He and Pony Head become cool with each other this way.
• Flanderization: People who mention Marco being overly safety conscious in the first episode only to be dropped afterwards don't realize that it's a weird inversion of this. This trait still shows up in other episodes (see the gift he made for his parents' anniversary in "Diaz Family Vacation", and the whole plan to keep Ferguson safe in "School Spirit"), but the first episode greatly exaggerated it at the cost of other parts of his personality, like being a little of a Neat Freak (as seen in "Quest Buy" or "My New Wand!"), or having an interest in psychology (as seen in "Sleep Spells").
• Foil: The series highlights his and Star's different reactions to the thought of having feelings for the other: While Star's feelings have been building up the more she was drilled despite saying otherwise, Marco remained indifferent to the possibility, not thinking anything would come of it. When it came to Star admitting she has a crush on Marco; Star attempts to avoid acting on it further, while Marco moves on and doesn't make a big deal about it... for a time.
• Friends with Benefits: Downplayed. He and Kelly become "breakup buddies" as they kiss and hold hands while dealing with their respective heartache. By the time of "A Boy and His DC-700XE", Marco broke up with her.
• Friend Versus Lover: He distrusted Tom when he introduced himself as Star's ex-boyfriend, although things improve between them, they are still a bit conflictive when Tom and Star are together again, however they get better then.
• Full-Name Ultimatum: Whenever Star is angry or annoyed with him then she'll call him by his first and last name.
• Future Badass: He was in multiple dimension for sixteen years and gained a six pack as well as alot of muscle but when he returns to earth, he is reverted back to his original age and body because it had only been eight minutes.
• Go Mad from the Revelation: Is temporarily driven insane after reading Eclipsa's section of the spell book in "Page Turner".
• Good Scars, Evil Scars: Zigzagged. In his adult form, Marco has a scar over his left eye but is no less the heroic badass. But, in his regular form, he doesn't have a scar.
• Good with Numbers: Zigzagged. Marco has good math skills and used the metric system to find Star's charger, but admits to Jackie that one of his many insecurities is over his inability to do long division.
• Gratuitous Spanish: Consider Marco is Hispanic, he does drop Spanish words or phrases occasionally.
• Has a Type: When "The Other Exchange Student" showed a picture of him getting kissed by a previous blonde foreign exchange student (Daniella from Belgium), fandom jokes that he's into blondes have cropped up since his crush Jackie is also blonde and he has had plenty of Ship Tease with Star.
• He Cleans Up Nicely: In "Bon Bon The Birthday Clown", both Star and Jackie are stunned when they see him dressed up for his dance date with Jackie.
• He Is All Grown Up: In "Running with Scissors", Star finds herself very attracted to his handsome adult version, calling him "Beautiful Stranger" before she even realizes who he is. It's humorously subverted a minute later when he and Star travel back to Earth and local time catches up with him, but she just happily pokes at the flab where his six-pack used to be.
  Marco: No! My hot bod! Where did it go!?
• Heroes Love Dogs: After Star creates a litter of laser puppies, he decided to take ownership of them.
• Heroes Prefer Swords: According to Janna's list of Marco's personal information in "Gift of the Card", one of his passwords is "O={==>SW0RD". In "Running with Scissors", 30-year-old Marco is a master swordsman.
• Heroic Build: Zigzagged. After spending over a decade searching for Hekapoo, he became absolutely ripped, but only has this form when in Hekapoo's dimension. Otherwise, Marco has a lean build. But, in either form, he's still heroic.
• Heroic Self-Deprecation:
  • In "Sleep Spells", it's revealed that he keeps a record of him and Star saving each other, and he resents the fact that she's saved him more times than he's saved her. After saving her from a hostile escaped princess, he tells her that he feels mundane by comparison, since she's a magical princess from another dimension. Star assures him that they don't need to compete, because he is certainly awesome.
  • In "Naysaya", it's implied that Marco is such a mess of insecurities that he actually wants to get physically punished for petty reasons.
    Marco (referring to the Naysaya): How do I get rid of it?
    Tom: Just let it run its course. Once it's shouted all your worst, most shameful secrets, it'll wear off.
    Marco: And how long will that take?
    Tom: It depends. How insecure are you?
    Marco: (Beat) Oh no...
• Hidden Depths:
  • He is shown to be knowledgeable about Victorian-era interior design.
  • He's also shown to be quite the film buff (in a rare VHS store, he clarified that he didn't mean the award-winning film when he asked for a pair of scissors).
  • Most dudes don't care about the differences between shades of the same color. He specifically dubs "Plum Purple" and "Prussian Blue" as his favorites.
  • In an effort to impress Jackie during "Sleepover", he shows that he can play jazz piano on his electric keyboard.
  • It's shown in "Friendenemies" that the kid can really sing.
  • As shown in "St. Olga's Reform School for Wayward Princesses" and "Death Peck", he has quite a knowledge of art.
  • The episode "Deep Dive" hints that Marco may have a hidden dark side to his careful, insecure nature. Something of note is that when he uses Star's wand, which changes its shape to reflect the person who uses it, the wand takes on an oddly sinister form, with a spear-tipped, spiked faceplate, decorated with a pair of bat wings.
• Hipster: Marco occasionally shows signs of being one, such as his "Space Unicorn" ringtone which is "supposed to be ironic."
• Humanity Is Infectious: Marco has a strong effect on non-humans. His humanity has rubbed off on Star and Tom and helped them mature and recognise the problems in their own lives.
• Hunk: His 30-year-old self certainly wasn't lacking in terms of rugged good looks.
• Hypercompetent Sidekick: To Star; he's a lot more savvy, patient, intelligent, and a much better strategist.
• Hypno Fool: In "Deep Dive", Marco claims he can't be hypnotized. But then Janna casually reveals that she hypnotized him ages ago and even put a trigger in him to make him fall asleep. He calls her out on her bluff but the moment Janna snaps her fingers and says "chickenbutt", he immoderately falls asleep.
• Hypocritical Humor: One episode has him point out that the martial arts are about honor and discipline. He then says that he wants to one-up some Spoiled Brat that takes classes with him.
• Icon of Rebellion: Kickstarted a princess revolution in St. Olga's School For Wayward Princesses, as "Princess Marco" overthrowing the initial regime and apparently turning it into a party school. This came complete with Barack Obama-styled posters and a huge amount of merchandise. Apparently, he gets a $650 royalty check for it, too. However, this is deconstructed later, because the students took his ideals too far and it caused their morals to dip to the point of having no sense of boundaries and cutting classes.
• I Know Karate: Marco uses karate to help in battles. The fact that he takes karate lessons and that he has a green belt probably helps.
  Star: You can fight?
  Marco: It's called... karate! (chops a monster)
• Improvised Weapon: Lacking a magic wand or a trademark weapon of his own, he makes do with what he can.
• Intergenerational Friendship:
  • Marco becomes friends with his karate sensei, Sensei Brantley. In fact, it seems that, after Star, Sensei is Marco's best friend.
  • Seems to have developed this with King River. He's more casual with the king than he is with the queen, and he even calls River by his first name with no title.
• Interspecies Romance: Downplayed. He (a human) and Kelly (a Woolett) become break up buddies before the latter breaks it off.
• In Touch with His Feminine Side: In "St. Olga's School for Wayward Princesses", despite initially disliking to be Disguised in Drag, by the end of the episode he refers to the captive girls as his fellow sisters and asks if he can keep the dress; he then only wears it when it's needed to hide his identity or help others. He wears it again in "Heinous". In "Princess Turdina" he reveals to the girls who idolize him that he is a boy by tossing off the dress. He wears it for the last time in "Divide" to bait Heinous, who now goes by her actual name Meteora. In "Gift of the Card" he wears ballet slippers, saying they're comfy to wear around the house. In "Friendenemies" it's revealed he's a big fan of the Boy Band "Love Sentence" (so does Tom Lucitor).
• I Resemble That Remark!: Marco complains that he doesn't know why people think he's so safety-obsessed while making sure Star avoids various minor hazards while walking.
  Marco: You wear a helmet in the gym shower one time and you're branded for life.
• Ironic Name: "Marco" manages to be this and a Meaningful Name. In Italian, "Marco" means "Mars" (the Roman God of War); it's ironic given his consciousness for safety.
• I Will Find You: He dedicates sixteen years of his life to find Hekapoo and defeat her clones. When Star leaves Earth after confessing her crush on him, Marco decides to go find her because "that's what friends do".
• Knight in Shining Armor: He isn't a knight yet. He is Star's right hand man and has such a high moral compass and strong determination that he can rally the "Marc-nificent Seven" together to assist him in distracting Meteora. In "The Knight Shift" he gets promoted, but ultimately turns it down because he realizes he doesn't want to spend his entire life devoted to Mewni. He's only willing to make that much of a commitment to Star.
• The Knights Who Say "Squee!": Marco is huge fan of Love Sentence, and it shows when Tom shows his shrine that is dedicated to Love Sentence. He also turns into a platonic Fanboy when Mackie Hand is resurrected.
• Kung-Shui: Marco is shown to use the environment to fight his enemies or destroy it in the process.
• The Lancer: While he and Star are co-protagonists, Star is the titular, central character whereas Marco is recognised as the deuteragonist. Marco is commonly the voice of dissent, is a Badass Normal to Star's magical abilities and finally Marco is the Straight Man to Star's wise guy.
• Lightning Bruiser: Marco became this so he can hunt Hekapoo and is revealed to have maintained it.
• Limited Wardrobe: Lampshaded in "Match Maker".
  Marco: I like red. I like hoodies. So I bought a dozen of them.
• Living Emotional Crutch: It's subtly implied that he is becoming this to Star, even more as she is entering in the dark path of magic. Any time that Star thinks she is losing Marco or he is in a real danger her magic becomes chaotic and uncontrolled and she gets mad.
• Lovable Jock: Marco is a karate practitioner and an all around Nice Guy.
• Lovable Nerd: Marco is a dorky kid (which is often mentioned by others), but it makes him quite endearing and well-liked.
• Love at First Sight: In "Here to Help", he claims that he always loved Star on some level (but wasn't yet aware of it) from the moment they first met.
• Love Epiphany: In "Mama Star", as the amnesia effect of the Realm of Magic starts to kick in, Marco rambles and argues with himself about how everybody else present has a reason to risk the trip but he doesn't, ending with the realization that he does in fact have a reason to be there: he loves Star. Then the magic fully buries his memories, sparing him from having to deal with the fact that his whole monologue was spoken out loud.
• Loving a Shadow: In "Sleepover", Marco admits that he's unsure about whether he has a crush on Jackie because of who she is as a person, or because he has put her on a pedestal in his mind.
• Lunacy: While his connections with the moon are yet to be explained. The Blood Moon presents itself to Marco while he was on a date with Jackie, which led to him discovering that Star was in danger. When Marco wields Star's wand, Marco gains a pair of crescent moon marks on his cheeks.
• Mage Killer: Marco can take on mages and demons with his knowledge and skills.
• Master Swordsman: Marco is one of the best swordsmen in Mewni, due to his experiences in the other realm.
• Masculine Girl, Feminine Boy: Star aside, he also has this dynamic with both Jackie and Janna, who are both tomboys.
• Meet Cute: Marco is tasked with keeping an eye on Star while she's trying to wrestle a water fountain.
• Moment Killer: In "Is Another Mystery", he accidentally interrupts an intimate moment between Star and Tom.
• Morality Pet: Downplayed. He and Hekapoo have an Odd Friendship and she doesn't change into a better person just because of her relationship with Marco, but does grow to care for him.
• Mr. Fanservice: In one episode, he spends 16 years in a dimension hunting clones of Hekapoo which results in him becoming an incredibly muscular, good-looking guy that made Star drool over. Even female fans of the show thought so as well.
• Muggle Best Friend: For Star. Though he is capable of serious butt-kicking himself.
• My God, What Have I Done?: Inverted during "Freeze Day" where he's more horrified by what he didn't do.
• Neat Freak: He always organizes all of his stuff, and even makes sure that his toiletries are not one inch out of place.
• Nice Guy: Unlike Star, who's more reckless and usually selfish, Marco's more of the level-headed Morality Pet. Not to mention, he's the "safe kid".
• Nice Job Breaking It, Hero: In "Heinous" it's revealed that Marco became the face of a revolution after releasing the captured princesses in St. Olga's Reform School, destroying the school in the process. As a result of the revolution the princesses became law-breaking and rule-disobeying anarchists.
• Non-Action Guy: Averted; despite being set up as the typical Muggle Best Friend, Marco is not totally useless in a fight relative to Star due to his karate training.
• Not So Above It All: Tries to convince Star to stop playing Flags when he sees how violent, ruthless, and divisive it is. Ends up stealing the win while everyone is distracted.
• Number of the Beast: Subverted. His dragon bike Nachos has the license plate number 667.
• Oblivious to Love: Marco seems to have no idea of Star's growing crush on him and how it's affecting her that he's now dating Jackie instead of her until "Face the Music" and "Starcrushed".
• Odd Friendship: With Hekapoo, a carefree, overconfident, trollish ageless being whose personality contrasts with his careful and responsible personality. The fact that she is still in contact with Marco after the Magic Commission's corruption is exposed says a lot about their friendship.
• Official Couple: By the end of the series with Star.
• Offscreen Moment of Awesome: He apparently spent 16 years in another dimension hunting Hekapoo which gradually turned him into a badass.
• Older Alter Ego: Marco's 30-year-old self in Hekapoo's dimension is more muscular and macho in personality than his scrawny teenage self.
• Older Than He Looks: Subverted. Thanks to his time spent in Hekapoo's dimension, Marco is chronologically in his early 30s, though he reverted back to his teenage body upon returning to Earth. When asked about this in one of his live streams, he described the events as a distant childhood memory, implying he is also mentally and emotionally a teenager again as well. Marco heads back to the Neverzone in Season 3 & 4, and we see teenage Marco become more confident and skilled because of his time there.
• Once Done, Never Forgotten: The one time he wore a helmet in the shower made the rest of the school brand him as the "Safe Kid".
• The One Guy: Since Alfonzo and Ferguson have had almost no screentime in season 2, Marco has become the only guy in a group of school friends consisting of himself, Star, Janna, Jackie, and StarFan13.
• Only Sane Man: Justified. His best friend is a Pretty Princess Powerhouse and Cloud Cuckoolander from another dimension who doesn't know anything about Earth culture.
• Ordinary High-School Student: Until he met Star.
• Our Founder: He founded the rebellion of princesses.
• Out of Focus: In Season 3, he loses a lot of airtime because of the show's increased focus on Mewni politics. It's somewhat appropriate, in that his subplot at the time is partly about having to deal with feeling sidelined and undervalued after he gave up everything to be with Star, but it means he's often absent or confined to comic relief cameos.
• The Paladin: He isn't a knight of Mewni yet but his fights against the likes of Hekapoo and Meteora show him as this.
• Pals with Jesus: He has Foe Romance Subtext-fueled Ship Tease with Hekapoo, a member of the Magic High Commission.
• Paper-Thin Disguise: His disguise as "Princess Marco Turdina" just feels rather forced and somewhat contrived; he doesn't look that much different with only a poofy dress and no changes to his hair aside from the addition of a ponytail, that it wouldn't look so convincing. Miss Heinous however, was easily fooled. So were the other princesses.
• Perma-Stubble: Marco's 30-year-old self has perma-stubble and is a Future Badass.
• Properly Paranoid: In "School Spirit", Marco believes that the school's rival football team are going to kidnap Ferguson like they used to do with the school's previous animal mascot despite everyone else thinking that it's crazy. Guess what happens the second Marco leaves him alone to talk to Star?
• Rank Up: In season 4, Marco starts off as Star's squire before transitioning to a Knight.
• Razor-Sharp Hand: He cuts off Tom's hand with a karate chop.
• Razor Wind: He learned this when he was hunting Hekapoo in "Running With Scissors". He uses his sword to direct wind at a pair of Hekapoos, which defeats one of them.
• Rebellious Spirit: Despite Marco claiming to be a rule-follower, his first instinct is to form a rebellion against institutions and rules he deems are wrong, such as against St. Olga's due to its use of brainwashing, and against Ludo in "The Battle For Mewni".
• Red Is Heroic:
  • Marco wears a red hoodie and is the deuteragonist of the series.
  • In "Red Belt", he becomes a red belt.
• Red Oni, Blue Oni: With Star, he is the safety-minded and level-headed Blue Oni and she is the energetic and wild Red Oni.
• Relationship Upgrade:
  • In "Naysaya" Marco finally asks out Jackie-Lynn Thomas and she invites him to go see a movie with her and the episode "Bon Bon The Birthday Clown" has Jackie asking him to go to the school dance with her which then turns into date and they share their First Kiss.
  • In "Here to Help", Star and Marco admit they love each other and officially become a couple.
• Rugged Scar: Marco's 30-year-old self has a scar on his left eye.
• Running Gag: Marco always has exactly $650 dollars on him to spend all at once.
• Safety Freak: Marco is known around his school as "the safe kid", chiefly due to the time he wore a helmet in the showers. During his and Star's first meeting, he guides her around every little obstacle in her way. He comes out of his safety bubble thanks to his dangerous adventures with Star and takes several levels in badass over the course of the series, but he always prefers the safe route to any danger and encourages his friends to avoid troubles when he can when he's not expressing enjoyment over fighting monsters.
• Save the Villain: Ends up saving the lives of Jeremy in "Monster Arm" and the Silver Hill Prep Warriors in "School Spirit" despite initially being antagonistic towards both parties.
• Sexier Alter Ego: His 30-year-old self is a tall, gorgeous Hunk with abs and a Rugged Scar.
• She Is the King: Inverted Trope. Marco is the founder of a group of rebellious princesses who fell under his banner when he led an uprising in St. Olga's. He eventually stepped down after admitting that he's a boy and Princess Arms soon took the mantle as leader.
• Sleeping Their Way to the Top: Downplayed. Higgs angrily tells Marco that the only reason he even is a squire is because he's the princess' boyfriend. Though she was wrong in Marco's relationship with Star as well as the many feats he has done, she did make a point on how easily he obtained his squire position.
• The So-Called Coward: Quick to Panic and Swift to Action.
• Socially Awkward Hero: Despite his enjoyment of fighting and capability of taking on monsters twice his size, he is very awkward around others and safety-minded in mundane situations.
• The Squire: Marco wanted to be a squire so he can eventually earn knighthood in Mewni, so he tries to be one for the only knight available. However Star doesn't want Marco to hurt himself, so she decides to make him her squire. But really, it's only a title.
• Straight Man: As the more savvy, levelheaded one, Marco is often this to Star, although he does have his own quirky traits.
• Strong Family Resemblance: Downplayed as a teenager, but Marco clearly inherited his brown hair and eyes as well as tan skin from his father. It becomes far more apparent with his thirty-year-old self, where he displays his father's height and Heroic Build to boot.
• Supporting Protagonist: While he is one the main protagonists, Star is the central focus.
• Talking the Monster to Death: Manages to get through to Tom with some choice words and a few dozen matches of ping-pong. He attempts to do so with both the Truth or Punishment box and the Friends-Til-The-End Quest Buy gift card, but fails.
• Tattoo as Character Type: When he was hunting Hekapoo for sixteen years, he gained a tribal tattoo of a pair of scissors on his left bicep, but he loses his tattoo when he returns to Earth.
• Taught by Experience: He was a green belt for a while, and, due to his master only being green at the time, never went past it for five years. From how much monster ass he's kicked despite that, it's shown that he's definitely made the most of those five years.
• The Team Normal: He was born and raised on Earth, and has had a relatively normal life.
• Teeth-Clenched Teamwork: With Pony Head before she warmed up to him.
• Thrill Seeker: Marco would like a little danger in his life. Thanks to Star, he got his wish by getting to fight monsters and go on interdimensional adventures on a nearly daily basis. And he couldn't be happier about it. Apparently, this is why he feels Earth is too limiting and mundane by Season 3.
• Trigger Phrase: Played for Laughs with "Chickenbut", which puts him to sleep in flash. And apparently, anyone can use it.
• Troubled, but Cute: Invoked. In a desperate attempt to rid himself of the title "Safe Kid", Marco tries to mold himself into a "misunderstood bad boy". Nobody buys it.
• Turn the Other Cheek: Marco has shown to be quite forgiving of those who have either annoyed and/or tried to hurt him, even Tom.
• Unholy Holy Sword: When he wields Star's wand, it doesn't look as heroic as it does when Star wields it. Marco also has several connotations with the Blood Moon.
• Uptight Loves Wild: Marco, who is bit of a Neat Freak and is even nicknamed "Safety Kid", has a crush on skater girl Jackie-Lynn Thomas, and has some Ship Tease with his very wild best friend Star.
• Victory Is Boring: After saving Mewni in the Season 3 premiere, Marco gets honorary knighthood and everything, but once he returns home, Marco can't quite celebrate his achievements back there, and feels life on Earth is just too limiting.
• Vitriolic Best Buds:
  • While Pony Head hasn't gotten over calling him "Earth Turd", she still sees Marco as one of her besties since their adventure in St. Olga's. Their relationship somewhat improved over time.
  • While they lean slightly more towards the vitriolic part, this is his and Tom's dynamic as of the conclusion of "Friendenemies". "Naysaya" implies that they've been hanging out off-screen, so a lot of their friendship is unseen, and Tom shows a rather friendly side to him.
  • Despite the trouble Janna likes causing for Marco, and his bitterness (and minor fear) towards her for doing so, they do value each other as friends.
• Vocal Evolution: In Season 1 Marco's voice was fairly deep, but had a tendency to crack occasionally (as is fitting for a boy his age). From Season 2 onward, Marco's voice has taken on a slightly higher pitch and become more prone to squeaking.
• Wacky Parent, Serious Child: Marco is more down-to-earth than his folks. He admits in "Goblin Dogs" that he's sometimes not sure whether he's the child and they're the adults or the opposite.
• Weak, but Skilled: He may just be an ordinary 14-year-old, but his impressive karate skills and tactics enable him to take on monsters and creatures much bigger than himself.
• Weaksauce Weakness: He easily gets carsick.
• Weirdness Magnet: Strange things usually happen to him because of Star because she considers it normal but there are times where weird things are encountered on his own such as the invisible goats or how he even met Star in a second and third time in the pilot. It's not just people or creatures from other dimensions he's attracted, Janna also applies to this as she frequently invades his personal space and teases him by stealing his house keys, having all of his personal details and finger prints and finally studies witchcraft and demonology through books which are stored in a secret panel behind his locker.
• Wholesome Crossdresser: He's put in a dress when sneaking into St. Olga's and pulls it off fairly well. By the end, he even asks to keep the dress, which comes back in "Heinous". Both times are treated as nothing out of the ordinary, and Marco seems to like wearing the dress. He does not identify as a female, despite enjoying women's clothing, and even laments the loss of his attractive and muscular adult body after he returns from another dimension where he was aged up. And of course, he decides he's finally tired of doing this because it's so uncomfortable.
• Would Hit a Girl: Marco will hurt a woman if it means protecting himself or his loved ones.
  • After failing to get through to Princess Smooshy via psychology, Marco simply throws a book at her.
  • He attacks Miss Heinous when he believes that she and her henchman are about to hurt his parents.
  • Frustrated with Higgs harassing him during their competition, Marco trips her feet.
• Would Hurt a Child: He was absolutely elated to beat Jeremy half-to-death with the help of Monster Arm and only stopped because he didn't want the arm to kill Jeremy and eat his bowels.
• You Are Better Than You Think You Are:
  • Star says as much to him in "Sleep Spells", where Marco feels worthless and ordinary in comparison to Star, a magic princess from another dimension. She assures him that he really is an awesome guy.
  • Done again this time by Jackie who after listing all of the dorky ways he's messed up already, tells him the fact he never gives up is what she finds most admirable and cool about him.

Allies and Close Friends

Thomas "Tom" Draconius Lucitor

"That was so much more fun than obliterating people!"

Voiced by: Rider Strong

The demon prince of Mewni's Underworld and Star's ex-boyfriend.

---

• All There in the Manual: Star and Marco's Guide to Mastering Every Dimension reveals his last name as Lucitor, before it is stated in the third season.
• Ambiguously Bi: Tom is shown to have an almost single-minded interest in Star and in no other person in particular, but he has made a number of comments that can give off the impression he is interested in Marco, including casually asking what Star would do if he kissed Marco and complimenting really tight swimwear on him.
  • In "Jannanigans", he clearly checks Oskar out when the group is at Britta's Tacos.
• The Antichrist: Subverted. He's listed as the son of "the Big Guy" in Star and Marco's Guide to Mastering Every Dimension. The episode "Club Snubbed" reveals that "The Big Guy" is actually a Mewman called Dave, with the nickname being in reference to his explosive temper.
• Ascended Demon: Tom wants to put himself in this direction, but it's very difficult for him to be good when by nature, his people are evil. He can't help it that he doesn't know how to do the right thing, and he even lamented that he's stuck being an evil demon forever. Thankfully, Star tells him that with guidance and effort, he can rise above his demon nature.
• Ascended Extra: While a major character in the episodes he appeared in, Tom's appearances in the first two Seasons were actually quite rare, amounting to no more than 3 or 4 episodes. Season 3, however, makes him a near constant presence, most likely due to his Relationship Upgrade with Star, and also serves as an Audience Surrogate along the way.
• Audience Surrogate: Most of his appearances post-"Demoncism" have him in this role, as his new Relationship Upgrade with Star allows the latter to express what she's going through for both him and the audience, and in some episodes all he does is react to the situation in the expected way the audience would. This becomes most notable in the Season 3 finale, where he's the only one who doesn't lose his soul(s), so that he can experience firsthand what the audience is seeing.
• Ax-Crazy: Oh yes. Pre-Season 2, he loses his cool really fast, and when he does you don't want to be anywhere near him.
• Berserk Button: In "Stump Day", Marco accusing Tom of being a bad boyfriend for forgetting Star's birthday makes Tom livid, enough to try beat the shit out of Marco without his demonic powers.
• Black Speech: He does ominous chanting in "Monster Bash" to summon a rune-carved coffin so he could trap Mina.
• Breakout Character: Tom made sporadic appearances in the first two Seasons, featuring in 3 or 4 episodes total, but his appealing character concept allowed him to gather a sizable fanbase, which led to much more prominent roles in Season 3 where he was essentially the third most important character behind Star and Marco.
• Burning with Anger: He spawns hellfire all over the place when he finally loses his temper in "Blood Moon Ball" and it seems to be something that happens often, though he starts losing it once he is better able to control his anger.
• But for Me, It Was Tuesday: Subverted in "Naysaya" where it's not that he forgot he put a curse on Marco but that he simply assumed the curse must have already come and gone by now and therefore saw no reason to warn Marco even though they were now on good terms. Plus, he couldn't get rid of it even if he wanted to. The nonchalant spirit of the trope is still fully intact, though.
• Character Development: Tom is introduced as Star's obsessed and irritable ex-boyfriend who is likely to be failing his treatment of his anger issues during season one. By the time he comes back, he is shown to be better at controlling his temper and even capable of eventually befriending Marco. Season 3 and 4 have a much sweeter and loving Tom, who is a very loving and supportive boyfriend to Star and Marco's best male friend and is among the nicest characters in the show. To whit: he goes from being a Crazy Jealous Guy over Star to breaking up with her himself because of I Want My Beloved to Be Happy.
• Cheaters Never Prosper: He spends most of the show's first three seasons trying to take shortcuts to manifest his character growth, not quite understanding that doing so would defeat the purpose. It takes the events of "Demoncism" where what he thought would be a quick and blasé procedure to cure his anger would take over a decade of frequent (and painful) rituals for him to finally decide to put the hard work into changing himself for the better.
• Chekhov's Gag: He is revealed to have several angry spirits living inside of him early in season 3. At the finale, it turns out this makes him resistant to Meteora's soul sucking powers since each spirit counts as a separate soul, making Meteora unable to turn him unresponsive like she did with others. Unfortunately, this provides little protection since Meteora just punches him out instead after getting tired of trying to drain all his souls.
• Chick Magnet: Tom gets the attention from a number of female students from Star and Marco's school.
• Claustrophobia: In "Is Another Mystery," he and Star are captured and have burlap sacks placed over their heads and most of their bodies. Tom seems calm at first, but then starts screaming and running around in a panic. When Star asks if he's okay, he responds in a shaky voice, "I think I just found out I'm claustrophobic, and I might be panicking a little."
• Control Freak: Tom's pet peeve is having things not go according to his plans. In his debut, Tom tries to remake the Blood Moon ball so it will appeal more to Star, but he even tries to make her conform to his desires, becoming irked when she refuses. The promotional poster for that episode even has him stringing Star around like he would a puppet.
• Converted Fanboy: He pretends to be a Mackie Hand fan in order to convince Marco to spend time with him, but he actually hates Mackie Hand movies and calls them garbage when the ruse is found out. He later expresses genuine impressment at Mackie Hand's martial arts while he and Marco are watching the guy's zombie fight security guards.
• Costume Evolution: From "Blood Moon Curse" in Season 4 onwards he wears a maroon jacket, a torn red t shirt, black jeans, and brown boots.
• Crazy Jealous Guy: He starts Burning with Anger when he thinks Star and Marco could be a thing and "Naysaya" reveals he put a curse on Marco just in case he tried to ask Star out. He grows out of it by the time he and Star are dating again.
• Deal with the Devil: He tries to trick Oskar into selling him his soul in Star and Marco's Guide to Mastering Every Dimension in exchange for success as a musician.
• Demonic Possession: He has thousands of tiny, angry souls living inside his body. While it does make him immune to the effects of soul-stealing like what Meteora did in the Season 3 finale, they're also the source of his anger issues, which makes him try a demoncism on himself to try get rid of his "inner demons".
• Demon Lords And Arch Devils: As a Devil Prince, Tom possesses an incredible amount of pull and power in the underworld, to the point that he was able to dramatically alter the demons' most beloved holiday in ways that aggravated the rest of them, just to impress Star. He likewise possesses incredible magical powers, being able to alter reality, summon objects and teleport between realms.
• Didn't Think This Through: His attempt at Heroic Sacrifice in the finale made Meteora more powerful, since, while he could resist her powers, she could still drain energy and get stronger from him. He even admits to it.
• Dishing Out Dirt: He can open up huge fissures in the earth which presumably lead to the underworld.
• Early-Bird Cameo: Tom had a brief cameo in "Match Maker" when Star accidentally called him on her mirror. He made his actual debut in "Blood Moon Ball".
• Elemental Personalities: He has fire powers, and he's a hothead with a Hair-Trigger Temper. It's also subverted; Tom acknowledges his anger as a serious problem and has been trying to control himself so he could be a better person, with varying degrees of success.
• Exhausted Eye Bags: Meteora's soul-stealing may not be a One-Hit Kill to Tom, but if his appearance is anything to go by it's having some effect on him.
• Exorcist Head: Inverted. Tom holds his head still so he can continue to give Marco a Death Glare while his body rotates as he and his anger-management counselor "walk it out".
• Fantastic Racism: He admits in "Is Another Mystery" that despite his wealth and status as an Underworld prince, he still gets funny looks and treated badly outside his kingdom because he's half-monster, and has to hide his tail to avoid receiving more prejudice.
• Fatal Flaw:
  • Tom always takes things to their logical extremes, and will not settle for less. He stops being a Stalker with a Crush? He acts like Star doesn't exist. He wants to be kinder and less temperamental? He insists on a very painful ritual to remove what causes his bad behavior and is hinted will effectively lobotomize him in the process.^note Though Tom doesn't seem to have realized this at the time. It doesn't behoove him to just give Star space in the former, or to just control his temper like a normal person in the latter, but that doesn't sound like fun for him.
  • His Hair-Trigger Temper. Being a demon with incredible political and magical power, having a short fuse could jeopardize him in both areas. Moreover, it's something that he got from his father, and he doesn't want to become like him. He does have an anger management coach and his friends to help him, but whenever he gets angry, something's going to be set on fire.
• Faux Affably Evil: He acts calm and polite throughout "Blood Moon Ball", but it turns out to be a ploy to get Star to dance with him under the light of the Blood Moon, which will bind them together as soulmates. He gets much better in his later appearances.
• Fiery Redhead: A pink-head, but Tom is definitely fiery in more ways than one, both in his early seasons temper and his fire powers.
• Foil: To Meteora, as they both represent the opposite options of society and family accepting a half-monster hybrid, especially those born into royalty. Where as Meteora is the daughter of a Mewman with a monster, a group of poor creatures that is hated by society, she suffers from it and has the throne taken from her. Tom on the other hand is largely beloved, if still suffering from Fantastic Racism in minor ways among Mewmans, he's still a royal who is the son of a Mewman with a demon that grants him a palace and the right to eventually govern the underworld.
• For Want Of A Nail:
  • The reason why he failed to dance with Star was because he wanted the dance with her to be absolutely perfect and he had left her alone for a brief moment so he can change one of the songs which allowed Marco an opportunity to have a moment alone with Star but Marco ends up becoming her soul mate instead of Tom.
  • He could have also got his wish in stopping Star and Marco going into a relationship, if he had inflicted the Naysaya curse on Star rather than Marco since "true love" applied to crushes. In "Blood Moon Ball" Star was the one with her heart on her sleeve and displayed an obvious attraction to the masked stranger.
• Forgot About His Powers: In "Is Another Mystery", he gets captured with a burlap sack put over his body and doesn't once use his demonic powers to free himself or Star, instead opting to run around aimlessly until he gets his horns stuck in a tree. Made more glaring because after he's freed and goes on to have a discussion with the monsters who captured him, he does actually display some of his demonic powers as part of the conversation. Partly justified in that the burlap sack caused him to discover that he's claustrophobic and he was possibly having a full on panic attack, and therefore wasn't thinking clearly.
• Friendless Background: He confesses in "Frenemies" that he doesn't have many friends. It's implied his temper and possibly his status as a demon prince drives people away.
• Glowing Eyes of Doom: Tom's eyes glow when he gets really angry. They're usually accompanied with a Voice of the Legion.
• Greater Need Than Mine: When he finds out Marco kissed Star. He initially didn't believe him and tried to sacrifice himself for Marco. When Marco confirmed the kiss and was incapacitated by Meteora, he chooses not to mention it again and protects Star.
• Hair-Trigger Temper: Despite his attempts to swallow his rage in "Blood Moon Ball", it's made obvious that the slightest things can set Tom off. It's all but stated that this was the major factor in Star's decision to break up with him.
• Heel–Face Turn: In "Mr. Candle Cares", Marco manages to convince him to give up his obsession with Star, and the three of them part on civil terms. In "Friendenemies" while it turns out his wanting to spend time with Marco was part of his anger management training, it's shown that he did enjoy it and started to like Marco more than he used to. By the next time he shows up, Tom reveals to have been hanging out with Marco offscreen and is a much nicer person.
• Helping Hands: Tom can still control his limbs after they've been severed and even reattach them.
• Heterosexual Life-Partners: Star and Marco's Guide to Mastering Every Dimension heavily implies that Tom desires a "bromance" with Marco and is a little hurt that he's not all that enthusiastic with the idea when the topic comes up. Later episodes do play them up as such.
• Hidden Depths:
  • While his bedroom in "Mr. Candle Cares" does have a torture wheel, everything else is what a wealthy teenager would have, including arcade machines, a ping-pong table, and posters on the walls.
  • According to Manfred and Star in "Club Snubbed", Tom is one of the best dancers on Mewni. They aren't lying - by the time Tom dances with Star, their dance ends up with a beautiful combination of fire and butterflies.
  • "Is Another Mystery" reveals that Tom himself has been subjected to Fantastic Racism, due to being half-monster. The fact he insists on being referred to as a demon and hides his tail indicates he has a fear of being treated as different, lesser than others or in the same camp as the mainstream monsters. It also explains that the treatment he received in "Starfari" was not a case of being mistaken for a monster; he is one, but he had to pull rank to save face.
  • He's also a huge fan of Love Sentence, a Boy Band, and even has a shrine dedicated to them. This is what allows him to start bonding with Marco, a fellow fan.
• Hollywood Genetics: Tom has pale violet skin; however his mom has dark red skin and his dad has human-like pale beige skin, presumably making Tom's a combination of both.
• Horned Humanoid: They resemble those of a bull.
• Hot as Hell: Many of the female students at Echo Creek Academy seem to find him attractive, one of them even whispered that "He's hot" when seeing him.
• Humanity Is Infectious: Despite initially hating Marco out of petty jealousy and paranoia, Tom has matured greatly because of his interactions with Marco.
• Hybrid Power: Is noted as being the strongest demon in the underworld and it'd take decades to properly remove all the demonic energy inside of him. He's also apparently half-Mewman, and given the only other known Mewman hybrid in the series is also immensely powerful, that is likely the cause of his abnormal power. Though he's not nearly as powerful as Meteora, however.
• Insistent Terminology: He's a demon, not a monster, which is a huge difference. In "Is Another Mystery", he admits he's a monster—a rich monster to be exact, but the title of demon heavily reduces the amount of Fantastic Racism he'd be subjected to.
• Interspecies Romance: Tom was in a previous relationship with Star, a Mewman. Downplayed, since it appears he's actually half-demon and half-Mewman. He is also the product of one, since his parents are a male Mewman and a demon Queen.
• I Want My Beloved to Be Happy: After his Heel–Face Turn, he accepts that he can't just force Star to love him, so he tries to give her space, even if she won't be with him. Ironically, this makes her want to restart her relationship with him. Ultimately this is part of why he breaks up with Star 2/3 of the way through the final season, though he also feels they're just moving in different directions and are no longer right for each other.
• Jerkass Has a Point: He (with Pony Head) rightly point out to Marco in "Stump Day" that celebrating Star's birthday on Stump Day would be a bad idea, and they tell him he should've at least asked Star what the preexisting conditions are for celebrating her birthday.
• Jerk with a Heart of Gold: Tom is a violent Control Freak with serious temper issues, but he's not so bad underneath all that. All his appearances post-"Blood Moon Ball" have him realize where he's gone wrong and try to make amends or, in the case of the Naysaya, where he can't do anything to fix it, at least tell Marco what will make it run its course.
• Just Friends: After their second breakup, Tom tries to deliberately defy this, saying that he doesn't want to make Star unhappy by being around her and reminding her of what she lost. Later episodes imply that they'll stay friends anyway, though.
• The Knights Who Say "Squee!": Tom has a shrine that is dedicated to the boyband Love Sentence, and this is what causes him and Marco to genuinely bond.
• Lack of Empathy: It's in his nature as a demon, so he really can't help it. Even when he wants to do the opposite of wrong, he still ends up doing the wrong thing anyways. He's trying to overcome it, however.
• Made of Evil: Why a demoncism is very painful—he's made up of countless evil, angry souls that it would require a thirteen year regimen for a complete treatment, and the process would either rob him of any personality whatsoever, or kill him. But, he does realize he doesn't have to be evil because of that.
• Many Spirits Inside of One: As mentioned above, he tries to get an "Inner demon" removed, only to find he has thousands. It becomes useful against Meteroa, as it prevents him from being rendered Only Mostly Dead like the others who got soul-sucked since he has so many, giving him enough time to escape.
• Mind over Matter: In "Mr. Candle Cares", Tom is able to undo Marco's chains without touching them and levitate ping pong balls.
• Modest Royalty: While he does wear formal suits for ceremonial events, his usual outfit (as shown in his folder image) makes him look like a punk rocker. His bedroom even reflects his tastes, resembling that of a teenager on Earth.
• Necromancer: In "Friendenemies", Tom displays the ability to resurrect the dead as zombies, reviving the martial arts movie star Mackie Hand.
• Never My Fault: He claims that his lack of friends stems from others judging him by appearance instead of his many, many, many other glaring flaws that are completely his own doing. Subverted as he gradually starts to take responsibility though.
• Nice Job Fixing It, Villain: When he invites Star to the Blood Moon Ball in an attempt to restart his relationship with her, he leaves Star alone for a moment to go and change the song, but Marco unintentionally steals the dance from him which results in Marco and Star becoming soul mates.
• Non-Human Humanoid Hybrid: Tom's father is a Mewman while his mother is a gigantic demon.
• No One Gets Left Behind: After everyone else in the Marc-nificent Seven has been drained of their souls, only Tom and Marco are left. Marco tells Tom to run while he holds the line, because someone needs to tell Star what has happened. Tom refuses to leave without Marco, sincerely telling him that he's his best friend, and even attempts a Heroic Sacrifice to save Marco from Meteora. This backfires since Tom has many souls, and the more souls Meteora absorbs the stronger she gets, so he only succeeds in making Meteora stronger, plus being in a continuous loop of getting successive souls sucked out with no time to react forces Marco to be the one to pull the Heroic Sacrifice, freeing Tom and telling him to run.
• Odd Friendship: He and Marco. Initially Tom tried to outright kill him more than once due to his jealousy over Star, over time the two become close friends, with Tom outright admitting that Marco is his best friend, and Tom pretty much being Marco's best friend, after Star.
• Our Souls Are Different: As a demon, it turns out that Meteora's soul-draining attack is of limited effect against Tom because each of his thousands of anger spirits counts as a separate soul. Though Tom failed to account for the fact that Meteora would still gain strength from each soul she sucked out of him. Also, the gaps between each soul-sucking were too short for Tom to move or counterattack.
• Playing with Fire: As is typical for a demon, he has fire powers. He can even use them to fly!
• Pointy Ears: Has a set of almost elf-like ears.
• Power Floats: Can pretty much fly at will, and does so in displays of power.
• Psycho Ex-Boyfriend: He hides a fierce temper beneath his affable demeanor. He tries to improve himself, though, and becomes nice enough for Star to get back together with him, even if he does occasionally slip back.
• Pyrrhic Victory: However Tom gets things, he just will never be satisfied, but thankfully he never reaches that point. In one instance, Tom wants to torture and then kill Marco for preventing him from getting Star back as his girlfriend, but Marco points out that even if he does the former, he will end up not succeeding in the latter. And in "Demoncism", Tom considers treatment to get rid of the worst part of himself, but it would be very painful and he would've become an Empty Shell as a result.
• Punched Across the Room: Courtesy of Meteora. It's also a One Hit K.O.
• Real Men Wear Pink: He's a massive fan of Love Sentence, a Boy Band. He also has a fluffy pet bunny.
• Red Eyes, Take Warning: A clear sign that he's lost it.
• Red Oni, Blue Oni: With his girlfriend Star as he is more connected to voicing his anger whereas Star is more collected about her thoughts and actions. In "Monster Bash" Star was the one that was trying to take a logical approach to handling the Mewman and Monster prejudices whereas Tom was more emotional by trying to spend time with Star. Extra points go to their respective kingdoms, Mewni's crest color is a light shade of blue whereas the underworld's crest is red.
• Reluctant Psycho: Even before his Heel–Face Turn, he is making genuine efforts to deal with his Ax-Crazy tendencies. This seems to have been motivated by his desire to get Star back and not wanting it to define his identity, but in his defense, he is still trying to improve even after having given up on her.
• Royal Brat: He's Underworld royalty and for very obvious reasons, has way more minions than actual friends. He also had a sense of entitlement, especially when it came to his ex-girlfriend, Star, whom he tried to control. However, he's come along way since his introduction.
• Rousing Speech: An interesting take on the trope: After Marco's plan to trap Meteora fails, everyone else seems to give up hope and ponder running away and hiding out. Tom then seems about to give a Rousing Speech, and starts out by saying that of course the plan was going to fail, and that Marco's next plan would probably fail too. But that Marco keeps coming up with plans anyway and doesn't give up, and that's why Marco is the leader, because one of his plans will always be Crazy Enough to Work. This works to rally everyone behind Marco again.
• Scary Teeth: All of his teeth are sharp. It's subverted later on as he tries to become a good person.
• Self-Fulfilling Prophecy: Tom has unintentionally caused Star and Marco to develop poorly timed and unrequited crushes on each other. Despite his former attempts to stop the pair from getting together, for example The Blood Moon Ball was organized to make him and Star soul mates but Marco unintentionally took his place in the dance to privately talk to Star when Tom left to change the song. On a another note, by the time that he and Marco have moved past their animosity and Tom gets back together with Star, Marco realizes he has a crush on Star when he sees her and Tom together.
• Shadow Archetype: To Star. They are both teenage royalty who possess great amounts of magical power, they are both charming and a lot of fun to hang out with, and they have serious problems with impulse control. However, while with Star this usually manifests with her acting before thinking, Tom has problems controlling his temper and preventing himself from lashing out when mad. Tom's displays of aggression are not so different from Star's own extreme tactics and reactions. They likewise have the habit of using their magic when emotionally upset, with devastating consequences.
• Shared Family Quirks: Hair-Trigger Temper (father) and emotional Power Incontinence (mother).
• Sharp-Dressed Man: He is sometimes seen wearing a suit. In fact, he's wearing it when he visits Star in "Mr Candle Cares" despite wearing his usual outfit in previous scenes, implying that he dressed up just for her.
• Shipper on Deck: After he and Star break up, Tom gives Marco his blessing should he want to pursue a relationship with Star.
  Tom: We're cool!
  Marco: Wait...! Were we not?
  Tom: Well with Star and I broken up now, I'm just saying it's cool if...
  Marco: If what?
  Tom: I mean, if you and your best friend, (motions to Star) ended up being something else, I wouldn't be mad.
  Marco: What?!? Tom the Blood Moon's Curse has been lifted. You were there.
  Tom: Come on Dude, I think we both know what you two have is something better than a curse.
• Significant Wardrobe Shift: Partway through the fourth season his regular outfit changes from shorts and a t-shirt to a new shirt, pants, and jacket. While this was likely the result of Eclipsa's "Low Self-Esteem Nightmare Dream" spell from "Swim Suit" it does look more mature than his original outfit.
• Sinister Surveillance: Parodied. Tom gloats to Marco in Star and Marco's Guide to Mastering Every Dimension that he cast a curse on him that would alert the demon prince of every time he says Star's name. Since Marco says Star's name all of the time, it's functionally useless and Tom's had to outsource the job of monitoring Marco's uttering of the word to one of his minions (lamer than it sounds) so he's only informed if it comes up in a romantic context (which, by the time the Guide was written, has only happened once). Given that Tom mistakenly thought that Marco and Star were dating after the events of "Face the Music" and never found out otherwise until Star told him in "Club Snubbed", it's likely that Tom deactivated this particular curse sometime around the end of season 2.
• Sole Survivor: He was the only member of the Marc-nificent Seven to not get taken out during their fight with Meteora. Luckily, they were all revived upon her defeat.
• Spell My Name With An S: He writes his full name as "Thomas" in "Death Peck", but it's spelled "Tomas" in The Magic Book of Spells. Either the book's spelling is a continuity error, or Star really thought it was spelled that way.
• Split-Personality Makeover: Subverted. As much as he really wants to change himself for the better, it doesn't happen overnight, as he ends up falling into his old ways to some degree. In "Demoncism", after he tries to get rid of his anger problems by doing the titular ritual, he learns that there is no quick fix for his anger and the result (becoming an Empty Shell or worse) isn't really worth the trouble.
• Story-Breaker Power: Tom is a demon with a truckload of powers that could end battles right then and there, so to mitigate this, Tom is subject to The Worf Effect many times in Season 3.
• Strong Family Resemblance: He's essentially his Mewman father Dave with demonic features, three eyes, and pink hair.
• Supernatural Sealing: Tom tries using a Black Speech incantation to seal Mina Loveberry in a runic stone box. It doesn't work and Mina takes out Tom herself.
• Tame His Anger: Tom acknowledges that his Hair-Trigger Temper is a serious problem and sincerely wants to overcome it, however, so far his attempts to get better have all ended in failure, and what he thinks will be a quick solution to his anger issues is actually more trouble than it's worth.
• Third Eye: Has a third eye on his forehead, much like his demon mother.
• Threesome Subtext: With Star and Marco at the end of season 3, with him being extremely close with both of them, and even being relatively OK with Marco kissing Star in the season 3 finale.
• Tom the Dark Lord: Tom is (initially) a Royal Brat whose anger issues match the political (and literal) firepower he wields. Bonus points for actually being named "Tom". Possibly justified as Mewni men tend to have more normal names than the women, and when their son was named, Tom's parents didn't expect how he would turn out later on.
• Took a Level in Kindness: His major form of displaying Character Development is how Tom has become a very supportive and loving boyfriend for Star and a good friend for Marco.
• Turn Out Like His Father: Tom doesn't want to be like his temperamental Mewman father, who also happens to be the King of the Underworld, and has been trying to control his anger issues.
• The Ugly Guy's Hot Daughter: Gender Inverted. Tom is an attractive humanoid with slight demon features while his mother is a gigantic Big Red Devil. His father appears to be a Mewman, so Tom clearly took after him for the most part.
• Visual Pun: He has fire powers, which show up in his appearance and hair when he's angry. He's a hothead.
• Vitriolic Best Buds: While they lean slightly more towards the vitriolic part, this is his and Marco's dynamic as of the conclusion of "Friendenemies". Subverted later on, where they drop the vitriolic part altogether.
• Voice of the Legion: When he's particularly pissed, he starts speaking this way, until the inevitable "burn something to a crisp". Possibly justified as he's the vessel of many angry souls inside his body.
• Weak, but Skilled: Downplayed; Tom's magic is seemingly weaker than Star's, but he is still incredibly powerful. Nevertheless, he is noticeably more skilled than Star is, with his casual ability to perform feats of power contrasting with Star's inexperience and manic attempts to control her wand.
• Yandere: Towards Star when he was introduced, having a twisted desire to make her love him again. Since them he has grown into a very loving boyfriend for her though.

Flying Princess (Lilacia) Pony Head

Voiced by: Jenny Slate

An aptly-named flying, talking, disembodied pony head who is also a Princess. Pony Head is an old friend of Star's that comes for a sudden visit not long after Star is sent to live with the Diaz's. While her wild and reckless behavior is pointedly shown to not be a good influence on Star, Pony Head does show a more honorable side, it's just hidden deep down. Really deep...

---

• Action Girl: Pony Head has shown to be very effective in kicking butt.
• Adaptational Attractiveness: In Daron Nefcy's original webcomic, Princess Pony Head was just as gaudy and sparkley as she is in the show, despite being an actual decapitated horse head, complete with glazed eyes, stuck-out tongue, and viscera leaking from her neck hole.
• Affectionate Nickname: Called "cupcake" by her father.
• All There in the Manual: Star and Marco's Guide to Mastering Every Dimension reveals her first name as Lilacia, and that she has 12 younger siblings. "Ponymonium" eventually confirms all those things.
• Ascended Extra: Only appears in two episodes in the first season, but for the second and third seasons she's been upgraded to recurring character.
• Best Friend: Star calls Pony Head her best friend on Mewni. Pony Head at first wasn't happy with the idea of sharing the position of Star's best friend with Marco, but later opens up to it.
• Big Sister Bully: Her sisters claim that she's this towards them in "Ponymonium", and there certainly seems to be some truth to that considering how she bosses them around while introducing them to Star.
• Brainwashed: Courtesy of St. Olga's. After the conditioning sets in, she speaks in a dainty, high-pitched "princess" voice completely drained of joy and can do naught but recite the mantras the school has drilled into her head and look as vapid as possible.
• Bullying a Dragon: Ponyhead often gets herself into trouble by overestimating herself. The best example being when she stole dimensional scissors from Hekapoo.
• The Bus Came Back: Forcibly sent to St. Olga's Reform School for Wayward Princesses in her introduction episode "Party with a Pony". She comes back in "St. Olga's Reform School for Wayward Princesses" and has appeared in a few episodes of the second season.
• The Chains of Commanding: Pony Head left St. Olgas because the other princesses started to see her as their leader.
• Character Development: Subtle, but unlike how she went into a Yandere-like fashion when Star introduced Marco as her friend, "Sleepover" has her matured enough to not do the same thing when StarFan13 expresses her extreme liking of Star.
• Childhood Friends: She and Star have known each other since they were toddlers.
• Clingy Jealous Girl: Pony Head becomes jealous of Star hanging out with Marco. She even threatens to impale him and almost "accidentally" knocks him off the cloud they were on. Judging from Star's reaction to Marco telling her this, this isn't the first time she's gotten "possessive".
• Consummate Liar: Has a nasty habit of lying, sometimes for legitimately planned reasons, other times just on the fly. Why she's hanging with Star in her introduction, what happened to Marco, where she got those Interdimensional Scissors, claiming to have eaten a Goblin Dog, or reasons why she'd be a non-flaky girlfriend, and the list goes on from there. It usually doesn't take long for her web of lies to unravel, after which Hilarity Ensues.
• Defrosting Ice Queen: Goes from ditching Marco out of jealousy to willingly (without provocation) going to save him from being tortured. By the end of "St. Olga's Reform School for Wayward Princesses", she actually considers him a friend, and "Goblin Dogs" is a (misguided) effort to do something nice for both of her "besties".
• Deliberately Bad Example: Pony Head serves as this for Star. Pony Head is extremely overdramatic, insanely spoiled, and not to mention a loose cannon at times. Star may not like rules and wants to do whatever she wants, but even she's put off by Pony Head's (along with her her siblings') behavior.
• A Dog Named "Dog": Played with; her real name is Lilacia, but she doesn't like being called that so everyone refers to her as "Princess Pony Head". It gets weird when even her family addresses her as such, despite them all being Pony Heads and thus every one of her sisters is also "Princess Pony Head".
• Do Not Go Gentle: Even wild horses couldn't drag her away from partying with her best bestie on the eve of her trip to St. Olga's Reform School.
• Embarrassing First Name: Lilacia.
• Everyone Calls Him "Barkeep": Enforced. She wants to be referred to as THE Princess Pony Head as she's none too fond of her first name. Luckily for her as the firstborn and heir to the throne, she is properly referred to as "Princess Pony Head".
• Fire-Forged Friends: Her dynamic with Marco in a nutshell.
• Green-Eyed Monster:
  • She acts antagonistic towards Marco for no valid reason except for petty jealousy, and Star states that this wasn't the first time Pony Head has gotten jealous.
  • She has contempt for all of her younger sisters except Azniss, who she has particular disdain for. It's implied that this animosity is due to how Azniss gets along really well with Star when it comes to her more tomboyish proclivities and the fact that as a capable magic warrior, she doesn't let herself take any guff from Pony Head.
• Heroic Comedic Sociopath: She has shades of this. "Sleepover" implies that she's killed before, and it's played for laughs. The same episode shows her to have a great ego when she proudly admits that her crush is herself. In "Goblin Dogs", Star admits that "Pony Head doesn't mean bad, she's just a liar." In "Running With Scissors", Star scolds her for stealing dimensional scissors from Hekapoo (who left them in the bathroom), to which Pony Head responds, "More like... finding?" and also is quite nonchalant when suggesting that Marco is "probably dead" after being dragged into Hekapoo's dimension, despite actually considering Marco a friend by this point. In "The Bounce Lounge", her idea to get everyone to leave Club Null is to set the place on fire (expressing surprise that this wasn't also what Star had in mind). And in "Bam Ui Pati!" she exploits her ex-boyfriend by pretending to get back together with him in order to escape from her sisters and watch her Korean Drama uninterrupted, then immediately dumps him once she's gotten over her depression over her broken horn despite him having just given her an even better prosthetic replacement horn.
• Heterosexual Life-Partners: With Star; "Freeze Day" shows that the two have been friends since they were toddlers.
• Hypocritical Heartwarming: While Pony Head is happy to insult her sisters, she won't let anyone else do it, even Star.
• I Choose to Stay: She decides to stay at St. O's, so she can make sure what happened to her doesn't happen to other princesses. Which turns out to not be that much of a sacrifice, since Pony Head and the other princesses tossed Miss Heinous out entirely and took over, turning St. O's into (in Pony Head's own words) "a total party school". She later ditches the place when some of the responsibilities of being a leader started to catch up with her.
• Insistent Terminology: Even after she accepts Marco, she demands Star acknowledge him as her "best bestie on Earth", as opposed to her "best bestie overall".
• Invisible Anatomy: She's able to eat despite, by her own admission, having no stomach.
• It's All About Me: She does what she wants with very little concern for the wants and needs of others, with Star being the only (possible) exception.
• Jerkass to One: She's mainly a jerk towards Marco due the latter being dubbed as Star's other "BFF".
• Jerk with a Heart of Gold: In general, she is the one making insensitive remarks. In her introduction, she comes off as selfish, petty and possessive of Star. She antagonizes Marco out of jealousy, going as far as to ditch him in another dimension and leave him to be tortured by the guards that are after her just so she could have Star all to herself. When Star calls her out on being a jerk to Marco, Pony Head understands how much Marco means to Star and willingly (without provocation) goes back to save him, even if it means letting herself be captured and taken to St. Olga's Reform School.
• Karma Houdini: As revealed in "Running with Scissors", the dimensional scissors that Star got from Pony Head were actually stolen from Hekapoo, though Pony Head suffers no repercussions for this, but Marco had to.
• Last-Name Basis: She's addressed by her family name. By her own insistence.
• A Lighter Shade of Black: As revealed in Star and Marco's Guide to Mastering Every Dimension, Pony Head is one of King Pony Head's Thirteen Daughters. Also revealed is how she's his heir because her siblings are unfit due to being too weird, too young, or outright worse than her. Even her youngest sister (who's still a baby) is already sociopathic enough to make Pony Head seem well-adjusted by comparison.
• Massive Numbered Siblings: She has twelve younger sisters.
• Manipulative Bastard: "Ponymonium" shows that she is one. She invited Star for dinner and then pretended to have a fit so Star would be accepted by her sisters. She then waited outside their door as they tried to involve Star in their plan and was recording it on her phone to foil it.
• Narcissist: Pony Head really, really, really thinks highly of herself. In "Sleepover", when the Truth or Punishment box asks everyone who their crush is, Pony Head pretends to be reluctant to admit that she has a crush on herself, which the box confirms is true.
• Projectile Spell: Pony Head can shoot beams from her horn.
• Really Gets Around: Downplayed. She's got a very flirtatious nature is the most likely one among Star's friends to chat with Star about boys, but given the show's target audience they the writers keep the details intentionally vague. Especially since the actual mechanics of any relationship a disembodied unicorn head might get into are better to not think about. She also once left the Silver Bell Ball with four guys, one of which was a sentient pigeon.
• Rebellious Princess: Her father had a hard time controlling her, which is why she was sent to "St. Olga's Reform School for Wayward Princesses", where Miss Heinous promptly sucked the spirit out of her.
• Screw This, I'm Outta Here: Sometime between St. Olga's Reform School for Wayward Princesses and the writing of Star and Marco's Guide to Mastering Every Dimension, she abandoned her fellow princesses when they started to turn to her for actual leadership, in matters that didn't involve partying. Like how some of them still wanted a genuine education system, then there was the matter of paying the building's electricity bill and the fact that they were quickly running out of food.
• Shipper on Deck: She "called it" that Star has a crush on Marco.
• Sticky Fingers: Pony Head tends to steal things quite a lot, like Hekapoo's dimensional scissors, gold and jewelry (and Prince Rich Pigeon) from the Pigeon Kingdom, and it's implied she stole a Truth or Punishment cube from the Magic High Commission.
• Vitriolic Best Buds: While she hasn't gotten over calling Marco "Earth Turd" (and labeling his disguised alter ego as "Princess Marco Turdina"), she does eventually consider Marco one of her "besties" after their adventures in St. Olga's.
• Yandere: A platonic version in her debut, for Star—Pony Head's pretty possessive of her status as Star's best friend and is initially very jealous of Star's friendship with Marco (even making some not-so-subtle attempts to get rid of him). But she eventually grows out of it, ultimately accepting Star and Marco's friendship and eventually accepting Marco as one of her "besties."

Janna Ordonia

"I know how to drop my pulse to zero, but only for sixty seconds."

Voiced by: Abby Elliott

A student at Echo Creek Academy and one of Jackie's friends. She like to dabble in "witchy" things and seems to have an interest in Star's Magic Instruction Book. In Season 2, Janna later become one Star's closest friends after "Girls' Day Out" and frequently takes part in her and Marco's adventures.

---

• Affectionate Nickname: Star calls her "Janna Banana" on occasion.
• Affectionate Pickpocket: Pickpockets Marco for his house key while offering to "make some magic" with him via Star's book.
• All There in the Manual: Star and Marco’s Guide to Mastering Every Dimension reveals that her last name is Ordonia.
• All Women Are Lustful: Much of Janna's dialogue with Marco is laced with plenty of innuendos such as "let's make some magic with it" when Marco finds Star's spell book and when she says that she wants Monster Arm to be her boyfriend. A more direct example is in "Bon Bon The Birthday Clown" where she slaps Marco's butt while he's wearing nothing but towels and tells him, "Ain't nothin' wrong with that!" after he got cologne on his backside, then sniffs the hand she spanked him with.
• Ambiguously Brown: Her skin tone is similar to Marco's, but her race is never mentioned. Her last name, Ordonia, is never mentioned in the show, but it suggests she's of Filipino descent. "Jannanigans" all but confirms this when Star, Marco, and Tom meet Janna's parents; the couple has Filipino accents and decor, and Janna's mom, Tala, shares a first name with the Tagalog goddess of stars.
• Ascended Extra: The character was originally created purely to serve as an obstacle for Marco to deal with in "Mewberty". The crew ended up liking the character enough to give her a more prominent role in the second season, having her befriend Star in "Girls' Day Out." In the last two seasons, she is the only Earth character besides Marco that continues to serve a role in the series, with characters questioning her regular appearances on Mewni serving as a Chekhov's Gag in the final season.
• Breakout Character: During the first season, Janna was a Recurring Extra who would be lucky to have more than two lines per episode. Her only relevant role in that season was in "Mewberty", but even in that episode she disappeared at the middle of it. Strong fan reactions towards the character turned her quickly into an Ensemble Dark Horse and she became one of Star and Marco's most recurring allies throughout the series. Although it wouldn't be until the final season that she would officially become a main character.
• Bunny-Ears Lawyer: Despite being a Nightmare Fetishist and being somewhat unsettling when she teases Marco, she is a valuable ally and highly useful in some episodes.
• Celeb Crush: She has one on John Keats.
• Chicken Joke: Most of the alternate timeline versions of Janna in "Mathmagic" have only a different punchline to this joke and a particular silly hat as the distinguishing features between them. The original Janna gives the classic Anti-Humor punchline when telling this joke to Star.
• Comedic Spanking: In "Bon Bon the Birthday Clown", Janna spanks Marco while he's wearing nothing but towels after he trips over her in the bathroom and spills cologne on his butt.
• A Day in the Limelight: "Girls' Day Out" featured her in a prominent role.
• Demon of Human Origin: She claims to have made herself a demon after splitting her soul in half in "Curse of the Blood Moon". When Tom says it doesn't work that way (it's still the same 100% human soul, just split in half), she amends her statement to half-demon, which he further refutes.
• Dreary Half-Lidded Eyes: Janna is often seen with partially lidded eyes, fitting her devil-may-care attitude.
• Early-Bird Cameo: Janna appeared as early as the first episode. Specifically, she appeared in Marco's first scene, sitting behind Jackie, with her head bending backwards and a pencil in her mouth. She then appeared as one of Jackie's friends in "Monster Arm", before getting a larger role in "Mewberty".
• Establishing Character Moment:
  • "Hey, [you] guys wanna see a dead possum? [...] Hahaha! I'm just messing with ya."
  • Prior to her proper introduction in "Mewberty", she made a brief appearance in "Monster Arm" in which her only line was expressing her desire for the titular arm to be her boyfriend.
• Figure It Out Yourself: She was already aware of Star's crush on Marco in "Bon Bon the Birthday Clown", but she never brings it up with either of them or Jackie.
• The Gadfly: Towards Marco. She steals Marco's house keys, wallet, and other bits of personal information just to annoy him. One episode reveals that she's even hypnotized him so he'd instantly fall asleep whenever someone says "chicken butt".
• Hidden Depths:
  • "Sleepover" reveals that her favorite color is pink, but she won't admit it to others because she hates contributing to gender stereotypes.
  • In "Jannanigans", she admits that her weirdness is at least partially an act that she puts on to help her feel in control, and she is actually very stressed out by unexpected strangeness.
• Improvised Weapon: In "Bon Bon the Birthday Clown", she fends off Ludo's rats with a hairdryer.
• Jerkass Has a Point: Janna's mischievous and trollish tendencies almost means that she has good insight into whatever situation she's involved with.
  • Her annoyance at Tom for constantly calling Star in "Junkin' Janna" is mostly self-interested, but also is because he's focusing too much on Star when he specifically came to hang out with her to learn how to stop doing so.
  • When Globgor is injured by Mina's Solarian sword in "Ready, Aim, Fire" and is ashamed of not being there for Eclipsa, Janna rightly points out that Globgor is too hurt to do anything.
• Jerk with a Heart of Gold: She is a constant tormentor to Marco and can be careless and snarky, yet she has shown concern with Star and Jackie's well-being. She's even been willing to help Marco on some occasions (albeit usually because she gets some schadenfreude out of it) and even tries to comfort him during the series finale, finally saying out loud that they're friends.
• Loveable Rogue: She's a known troublemaker and she often teases Marco but it doesn't lessen her friendship with him.
• Magic Skirt: Janna's skirt is never effected by the environment. This was best shown in "Junkin' Janna", where she was unaffected by the wind while riding Sebastian the crow.
• Nightmare Fetishist: She likes all things that are "witchy" and she even once outright said she wanted Marco's monster arm to be her boyfriend. In "Interdimensional Field Trip", her idea of a fun field trip is going to a morgue, and she briefly dates a skeleton vampire. In "Cornonation", she tells Eclipsa that she "gets it", upon meeting Globgor.
• Noodle Incident: In Star and Marco's Guide to Mastering Every Dimension, when Star interviews her about her experience with dating Bernardo the vampiric skeleton from "Interdimensional Field Trip", she speaks fondly of the brief relationship, yet gives an immediate "NO" when Star asks if she'd ever date him again, with no explanation for what happened between them that caused her adamant refusal of the idea.
• Odd Friendship: Janna and Marco do hang out now and again, though it takes until the final episode for her vocalize that this is what she views their dynamic as, with Marco almost shocked to hear her acknowledge him as anything but a plaything. They can occasionally be seen hanging out, such as her being with him and Jackie in "Rest in Pudding" or playing a card game with him and his friends in an earlier episode. The oddities are mainly shown in her constantly pick-pocketing his stuff and flirting with him, with her present to him in "Sophomore Slump" being his social security card.
• O.O.C. Is Serious Business: Janna is a well known Nightmare Fetishist. So, when she decides that she and Tom should run away from a crow (Sebastian) that can turn into a monstrous form, then something is wrong.
  • Janna screams after Quirky Guy dies in front of her.
• Our Souls Are Different: She split her soul in half in "Curse of the Blood Moon".
• Out of Focus: Downplayed in comparison to the other human characters. Although Janna had a significant amount of screen time given to her in Season 2, she only appears a small handful of times in Season 3, despite having been promoted to a more prominent spot in the opening sequence. Reversed completely in Season 4, where Janna becomes a core member of the main cast.
• Perky Goth: Is quite upbeat and cheerful, and also a lover of all things macabre.
• Playing Possum: In the Grand Finale, she reveals she can shut down her pulse for 60 seconds.
• Security Cling: Does this with Jackie in "Bon Bon the Birthday Clown", hiding behind her as she fends off rats.
• Shipper on Deck: Implied. When she finally meets Globgor face-to-face, she takes a picture of him and states, "I get it, Eclipsa". She then urges Globgor to join in Eclipsa's song.
• Stalker with a Crush / Stalker without a Crush: She has stolen Marco's house keys and has a list of all of Marco's personal information, including his SSN and fingerprints, among other invasions of privacy. It's also revealed in "Naysaya" that she keeps some personal items such as a book on demonology, witchcraft, and curses behind a secret panel in Marco's locker. When asked how she has the combination to his locker, she says that obviously she got it from reading his diary. There's no explicitly stated reason as to why she does this, but she most likely does it to tease him and to entertain herself. Her somewhat flirtatious behavior toward Marco could indicate that she has feelings for him or has a playful attraction towards him. Whether she chose Marco specifically as her target is because of a crush or just because his reactions are more fun is up in the air.
• Stalking Is Funny if It Is Female After Male: Her behavior towards Marco is usually Played for Laughs. Star also sees Janna's behavior as innocent and non-vindictive.
• The Tease: Towards Marco.
  Janna: I think we all know who I have a crush on, don't we, Marco?
  Marco: Uh...
  Janna: Eighteenth-century poet John Keats.
• The Teetotaler: She states in Star and Marco's Guide to Mastering Every Dimension that she doesn't drink because that would desecrate the occult temple that is her body. Why a fourteen-year-old would be drinking alcohol in the first place is a mystery, but at least it's confirmed that she doesn't do that.
• Token Evil Teammate: Downplayed. Evil is pushing it, though she is associated with the occult and is a frequent troublemaker whose common target for mischief and thievery is Marco. In school, she is a frequent attender of detention.
• Tomboy and Girly Girl: She is the Tomboy to Star's Girly Girl.
• Tomboyish Voice: She's tomboyish and has a low-pitched, gravelly voice.
• Tomboy with a Girly Streak: She's nowhere near as girly as the likes of Star (and outright admits to hate "contributing to gender stereotypes") and takes a liking to macabre things and pranking, yet she wears a skirt and confessed in one episode that her favorite color is pink.
• Troll: Janna is a good friend to Star and Marco but she enjoys teasing Marco more. Janna's interactions with Marco can range from annoying (constant pick-pocketing), to flirtatious, to down right unsettling (creating an army of evil Marcos). Janna doesn't always appear to be on Marco's side (like stealing his possessions, breaking into his wallet and even hypnotising him for laughs), but does care about him and roots for him during their adventures. In "Sophomore Slump", she's the only one who cuts Marco a break during their tabletop role-playing game. In "Curse of the Blood Moon", Janna renders Marco unconscious to help him remove his feelings for Star. Finally, she was aware of Marco's crush on Jackie-Lynn Thomas but she did nothing and said nothing to Jackie about it, only laughing after Marco embarrassed himself when attempting to ask Jackie out on a date.
• Vitriolic Best Buds: Despite the trouble she likes causing for Marco, and his bitterness (and minor fear) towards her for doing so, they do value each other as friends.
• Vocal Evolution: Her voice is noticeably raspy in "Mewberty", but by her next major appearance, her voice settles into what it will be for the rest of the series.

Kelly

Voiced by: Dana Davis

A friend of Pony Head's. A humanoid being called a Woolett with bush-like hair that doubles as a sort of Pocket Dimension.

---

• Action Girl: She's a skilled sword user, and in fact has several of them.
• Blood Knight: Loves to fight. "Kelly's World" reveals that this trait is typical for her entire species, and that her home world's culture is based around fighting.
• Blush Sticker: Kelly's cheeks have permanent pink blushes on them.
• Emo Teen: After her final breakup with Tad she has random points where she sulks, becomes more sullen and emotionally sensitive.
• Friends with Benefits: Downplayed. She and Marco become "breakup buddies" as they kiss and hold hands while dealing with their respective heartache. By the time of "A Boy and His DC-700XE", Marco has gotten over his pain and broke up with her.
• Hammerspace Hair: As gigantic as her hair is, it is Bigger on the Inside. It's to the point the inside of her hair is practically a cave that Marco can easily walk around in, even though Marco is taller than Kelly without Tad.
• Hopeless Suitor: Zigzagged. If Janna's comment in "Stump Day", and Kelly's fumbled reaction is to be believed, Kelly has developed a crush on Marco who either doesn't reciprocate her crush on him or is too busy pining for Star to realize it. Though, we do see Marco regards Kelly as more of a consolation when dealing with his confused feelings for Star. Come "Kelly's World", they become break-up buddies to deal with the fallout from their respectively relationships for a few episodes until Marco breaks it off, much to her annoyance.
• Human Aliens: Kelly looks like a human but has mint-green hair, no nose, and her hair is like an apartment/pocket dimension on the inside. "Kelly's World" reveals that her species are called "Wooletts" and they all have extremely long hair that's worn like fluffy coats; Kelly just happens to like tying hers back. We don't see what any others look like under the coats, but some are implicitly much less humanoid than Kelly, and some are beings that split into smaller beings if they get hit real hard. Others, like her mom, are building-sized and act as homes for their families.
• Interspecies Romance: Downplayed. She (a Woolett) and Marco (a human) become break up buddies before the latter breaks it off.
• Non-Standard Character Design: Her face has a much more simplistic design than any other character in the show, with her having no nose, small pupils with no irises, and her eyes not being separate from each other.
• The Noseless: One of the indicators that she isn't quite human.
• Planet of Copyhats: "Kelly's World" reveals that her entire species is very hairy and obsessed with fighting, up to and including having an economy based around punching each other.
• The Quiet One: Doesn't talk much before revealing that Goblin Dogs are real. She's more vocal in her subsequent appearances.
• Relationship Revolving Door: Apparently it's common for her and Tad to break up only to get back together. This happens multiple times a week. Kelly eventually got tired of it and decides to end it for good. This is what makes Tad so unwilling to accept it and move out when they break up for real in "Lava Lake Beach". By "Kelly's World", it turns out Kelly herself isn't ready to break off entirely, hence why she keeps accepting his calls, in spite of him being even more arrogant now than ever.
• Romantic Fusion: When she and Tad are together, Tad spends most of his time blending into Kelly's hair. Right around when Kelly and Marco becoming "breakup buddies", they learn a fighting technique where both of them are covered by Kelly's hair and fight in tandem.
• Shout-Out: Her face resembles that of Kero Kero Keropi, to an extent.
• Single Woman Seeks Good Man:
  • Tad seems like a pretty chill dude. He willingly listens to Marco as he pours his heart out (though Marco didn't know), and, despite being a vegan, he willingly accompanies Kelly to a hotdog stand because he just likes to hang.
  • Kelly later starts getting some Ship Tease with Marco.
• Throwing Your Sword Always Works: A tactic she uses against Meteora in "Divide".
  Meteora: You could've put out someone's eye!
• Tiny Guy, Huge Girl: With Tad, as he is barely a foot tall while Kelly is average size for a teenage girl.
• Trademark Favourite Food: Goblin Dogs.
• Walking the Earth: Or in this case, travelling the multiverse is what Kelly does on a regular basis, fighting monsters and all.
