Main Heroes


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 Siblings: 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 Buttons:
    • 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.
  • 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.
  • 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. They ignore them, so they can go away on their own, rather than talk to each other about them.
  • Kid Hero: Both are 14-15 years old and are co-protagonists.
  • Embarrassing Nicknames:
    • 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:
  • 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.
  • 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'.
  • Only Child Syndrome:
    • Star is the only child of the King and Queen of Mewni.
    • Subverted with Marco, like Star, he was an only child until his mother got pregnant in "Marco Jr".
  • 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 have each shown an awkward physical attraction to the other at some point. Perhaps inevitably, Star is revealed to have a complicated crush on Marco that even she wasn't really aware of at first.
  • 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.
  • Your Cheating Heart:
    • Though unintentional, Marco technically had an emotional affair with Star in the weeks after Toffee's defeat while he's dating Jackie, leaving Earth to go to Mewni and staying there for weeks without telling anyone, her included, to live with Star, who he knew had a crush on him and for whom he was developing feelings.
    • Star ends up getting back together with Tom in Season 3, but she and Marco end up sharing a kiss while trapped in a photo booth during "Booth Buddies" thinking they were stuck 'til they did so. Thankfully, Tom understood it wasn't Star's fault that a goblin forced them to do it.

Hero's 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 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 Anti-Christ: 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 proteciton 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.
  • 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".
  • 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.
  • Mixed Ancestry: His mother is a demon and his father appears to be a Mewman.
  • 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. 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.
  • Personality Powers: 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.
  • 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.
  • Reality Ensues: 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.
  • 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.
  • 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.
  • 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.
  • You Gotta Have Blue Hair: Tom has pink hair.

    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.
  • Frickin' Laser Beams: Pony Head can shoot beams from her horn.
  • 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: Selfish, self-centered, narcissistic, pushy, and sometimes ungrateful.
  • 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.
  • Really Gets Around: Downplayed. She flirts a lot and she 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.
  • Static Character: She's a snarky, entitled pony who mainly looks out for herself, and doesn't grow out of it, even in her focus episodes.
  • 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 still sees Marco as one of her besties since their adventure in St. Olga's.
  • Yandere: A platonic version in her debut, for Star. Pony Head is not happy that Star has found another best friend in Marco and makes not-so-subtle attempts to get rid of him. She later warms up to Marco and grows out of it.
  • You Gotta Have Blue Hair: She has a pink mane.

    Janna Ordonia
"I know how to drop my pulse to zero, but only for sixty seconds."
Voiced by: Grey DeLisle (season 1), Abby Elliott (season 2 onward)

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 Script: 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", with the crew 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.
  • 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 Nice 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.
  • Early-Bird Cameo: Janna 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? Ha, I'm just messing with you."
    • 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".
  • Girls Are Really Scared of Horror Movies: Inverted. In "Starcrushed", she is first seen watching a horror film and laughing at it.
  • 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: Mischievous and trollish tendencies aside, Janna does occasionally have good insights.
    • 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 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 loud out that they're friends.
  • Loveable Rogue: She's a known a 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.
  • Maybe Magic, Maybe Mundane: She claims the fangs she used to scare Marco weren't real. But considering she was tied up at the time and hid them rather well for her prank, not to mention the last time we saw her before being captured by the yarn monster was taking a selfie with a vampire skeleton throws some doubt to that. Plus she's a chronic pickpocket and lover of the macabre, so it's kinda hard to take anything she says at face value. Also, note that she said to Marco that they "weren't real fangs... unless you want them to be."
  • Nice Hat: She's almost always seen wearing her olive-colored beanie. "Mathmagic" shows many alternate timeline versions of her distinct only in her choice of Nice Hat and her punchlines for the Chicken Joke.
  • 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 "Coronation", 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 in "Interdimemsional 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 weird 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 with 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 (most of them being within the season's first half). And 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.
  • Static Character: She's just the generic cool chick with a dark streak, and not much in the way of character development , mainly just being there in a supporting role.
  • 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 her favorite color is pink.
  • The Trickster: She is shown to be a rather mischievous person. Her favorite victim is Marco but she enjoys playing with others like Star as well.
  • 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), 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.
  • You Gotta Have Blue Hair: Janna has dark blue hair.

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.
  • Ambiguously Brown: She has dark skin with mint-green hair, but her ethnicity is unknown since she isn't a human.
  • Blinding Bangs: Covering not just her face, but her whole body. Her eyes remain visible though.
  • 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 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 Alien: 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.
  • Meganekko: It might be a bit difficult to notice, but she actually wears a pair of large round glasses.
  • 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.
  • Rapunzel Hair: She boasts a head of very voluminous hair, extending past her knees and several times wider than her body. Her hair's texture made her look like a bush on legs a la Cousin Itt before she pulled back her bangs.
  • 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.
  • You Gotta Have Blue Hair: Kelly has mint green hair.
