!Hero's Allies and Close Friends

[[folder:Thomas "Tom" Draconius Lucitor]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/tom_svtfoe.png]]
[[caption-width-right:350:''"That was so much more fun than obliterating people!"'']]
->'''Voiced by''': Creator/RiderStrong

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

* AllThereInTheManual: ''Star and Marco's Guide to Mastering Every Dimension'' reveals his last name as Lucitor, before it is stated in the third season.
* AmbiguouslyBi: Tom is shown to have an almost [[SingleTargetSexuality 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.
* TheAntiChrist: Subverted. He's listed as the son of "[[{{Satan}} 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.
* AscendedDemon: 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.
* AscendedExtra: 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 RelationshipUpgrade with Star, and also serves as an AudienceSurrogate along the way.
* AudienceSurrogate: Most of his appearances post-"Demoncism" have him in this role, as his new RelationshipUpgrade 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.
* AxCrazy: ''Oh yes''. Pre-Season 2, [[HairTriggerTemper he loses his cool really fast]], and when he does you don't want to be anywhere near him.
* BerserkButton: 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.
* BlackSpeech: He does ominous chanting in "Monster Bash" to summon a rune-carved coffin so he could trap Mina.
* BreakoutCharacter: 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.
* BurningWithAnger: 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.
* ButForMeItWasTuesday: 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.
* CharacterDevelopment: 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 CrazyJealousGuy over Star to [[spoiler: breaking up with her himself because of IWantMyBelovedToBeHappy.]]
* CheatersNeverProsper: 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.
* ChekhovsGag: 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 [[MundaneSolution Meteora just punches him out instead]] after getting tired of trying to drain all his souls.
* ChickMagnet: 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."
* ControlFreak: 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 [[https://vignette.wikia.nocookie.net/star-and-the-forces-of-evil/images/f/fe/BMB_evonfreeman.jpg/revision/latest?cb=20150716034331 promotional poster]] for that episode even has him stringing Star around like he would a puppet.
* ConvertedFanboy: 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.
* CostumeEvolution: From "Blood Moon Curse" in Season 4 onwards he wears a maroon jacket, a torn red t shirt, black jeans, and brown boots.
* CrazyJealousGuy: He starts BurningWithAnger 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.
* DealWithTheDevil: 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.
* DemonicPossession: 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".
* DemonLordsAndArchDevils: 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.
* DidntThinkThisThrough: His attempt at HeroicSacrifice 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.
* DishingOutDirt: He can open up huge fissures in the earth which presumably lead to the underworld.
* EarlyBirdCameo: 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".
* ElementalPersonalities: He has fire powers, and he's a hothead with a HairTriggerTemper. 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.
* ExhaustedEyeBags: Meteora's soul-stealing may not be a OneHitKill to Tom, but if his appearance is anything to go by it's having ''some'' effect on him.
* ExorcistHead: 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".
* FantasticRacism: 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.
* FatalFlaw:
** Tom always takes things to their logical extremes, and will not settle for less. He stops being a StalkerWithACrush? 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.[[/note]] 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 HairTriggerTemper. 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.
* FauxAffablyEvil: 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.
* FieryRedhead: 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 [[ForWantOfANail 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 FantasticRacism 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.
* ForWantOfANail:
** 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.
* ForgotAboutHisPowers: 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 [[{{Claustrophobia}} claustrophobic]] and he was possibly having a full on panic attack, and therefore wasn't thinking clearly.
* FriendlessBackground: 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.
* GlowingEyesOfDoom: Tom's eyes glow when he gets ''really'' angry. They're usually accompanied with a VoiceOfTheLegion.
* GreaterNeedThanMine: 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.
* HairTriggerTemper: 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.
* HeelFaceTurn: 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 [[ItMeantSomethingToMe he did enjoy it]] and [[BecomingTheMask 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.
* HelpingHands: Tom can still control his limbs after they've been severed and even reattach them.
* HeterosexualLifePartners: ''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.

** 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 FantasticRacism, 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 BoyBand, and even has a shrine dedicated to them. This is what allows him to start bonding with Marco, a fellow fan.
* HollywoodGenetics: 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.
* HornedHumanoid: They resemble those of a bull.
* HotAsHell: 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.
* HumanityIsInfectious: Despite initially hating Marco out of petty jealousy and paranoia, Tom has matured greatly because of his interactions with Marco.
* HybridPower: 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.
* InsistentTerminology: 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 FantasticRacism he'd be subjected to.
* InterspeciesRomance: 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.
* IWantMyBelovedToBeHappy: After his HeelFaceTurn, 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. [[spoiler: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.]]
* JerkassHasAPoint: 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.
* JerkWithAHeartOfGold: Tom is a violent ControlFreak 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.
* JustFriends: [[spoiler: After their second breakup, Tom tries to deliberately [[DefiedTrope 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.]]
* TheKnightsWhoSaySquee: Tom has a shrine that is dedicated to the boyband Love Sentence, and this is what causes him and Marco to genuinely bond.
* LackOfEmpathy: 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.
* MadeOfEvil: 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.
* ManySpiritsInsideOfOne: As mentioned above, he tries to get an "Inner demon" removed, only to find he has ''thousands''. It becomes useful against [[YourSoulIsMine Meteroa]], as it prevents him from being rendered OnlyMostlyDead like the others who got soul-sucked since he has so many, giving him enough time to escape.
* MindOverMatter: In "Mr. Candle Cares", Tom is able to undo Marco's chains without touching them and levitate ping pong balls.
* ModestRoyalty: 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.
* NeverMyFault: 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|Trope}} as he gradually starts to take responsibility though.
* NiceJobFixingItVillain: 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.
* NonHumanHumanoidHybrid: Tom's father is a Mewman while his mother is a gigantic demon.
* NoOneGetsLeftBehind: 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 [[BringNewsBack tell Star what has happened]]. Tom refuses to leave without Marco, sincerely telling him that he's his best friend, and even attempts a HeroicSacrifice 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 HeroicSacrifice, freeing Tom and telling him to run.
* OddFriendship: 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.
* OurSoulsAreDifferent: As a demon, it turns out that Meteora's soul-draining attack is of limited effect against Tom because each of his [[ManySpiritsInsideOfOne 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.
* PlayingWithFire: As is typical for a demon, he has fire powers. He can even use them to fly!
* PointyEars: Has a set of almost elf-like ears.
* PowerFloats: Can pretty much fly at will, and does so in displays of power.
* PsychoExBoyfriend: 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, [[ReformedButNotTamed even if he does occasionally slip back]].
* PyrrhicVictory: 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 EmptyShell as a result.
* PunchedAcrossTheRoom: Courtesy of Meteora. It's also a One Hit K.O.
* RealMenWearPink: He's a massive fan of Love Sentence, a BoyBand. He also has a fluffy pet bunny.
* RedEyesTakeWarning: A clear sign that he's lost it.
* RedOniBlueOni: 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.
* ReluctantPsycho: Even before his HeelFaceTurn, he is making genuine efforts to deal with his AxCrazy tendencies. This seems to have been motivated by his desire to get Star back [[https://ohmy.disney.com/insider/2015/07/20/creator-daron-nefcy-guides-us-through-tonights-star-studded-episode-of-star-vs-the-forces-of-evil/ 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.
* RoyalBrat: 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 [[CharacterDevelopment come along way since his introduction]].
* RousingSpeech: 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 RousingSpeech, and starts out by saying that [[{{Subverted}} of course the plan was going to fail]], and that Marco's next plan would probably fail too. But that [[{{Determinator}} Marco keeps coming up with plans anyway and doesn't give up]], and that's why [[DoubleSubverted Marco is the leader]], because one of his plans will always be CrazyEnoughToWork. This works to rally everyone behind Marco again.
* ScaryTeeth: All of his teeth are sharp. It's subverted later on as he tries to become a good person.
* SelfFulfillingProphecy: 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.
* ShadowArchetype: 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 [[LeeroyJenkins 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.
* SharedFamilyQuirks: HairTriggerTemper (father) and emotional PowerIncontinence (mother).
* SharpDressedMan: 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.
* ShipperOnDeck: 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.
* SignificantWardrobeShift: 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.
* SinisterSurveillance: 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.
* SoleSurvivor: 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.
* SpellMyNameWithAnS: He writes his full name as "Thomas" in "Death Peck", but it's spelled "[[MyNaymeIs Tomas]]" in ''Literature/TheMagicBookOfSpells''. Either the book's spelling is a continuity error, or Star really thought it was spelled that way.
* SplitPersonalityMakeover: 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 EmptyShell or worse) isn't really worth the trouble.
* StoryBreakerPower: 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 TheWorfEffect many times in Season 3.
* StrongFamilyResemblance: He's essentially his Mewman father Dave with demonic features, three eyes, and pink hair.
* SupernaturalSealing: Tom tries using a BlackSpeech incantation to seal Mina Loveberry in a runic stone box. It doesn't work and Mina takes out Tom herself.
* TameHisAnger: Tom acknowledges that his HairTriggerTemper 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.
* ThirdEye: Has a third eye on his forehead, much like his demon mother.
* ThreesomeSubtext: 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.
* TomTheDarkLord: Tom is ([[CharacterDevelopment initially]]) a RoyalBrat 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.
* TookALevelInKindness: His major form of displaying CharacterDevelopment is how Tom has become a very supportive and loving boyfriend for Star and a good friend for Marco.
* TurnOutLikeHisFather: 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.
* TheUglyGuysHotDaughter: {{Gender Inverted|Trope}}. Tom is an attractive humanoid with slight demon features while his mother is a gigantic BigRedDevil. His father appears to be a Mewman, so Tom clearly took after him for the most part.
* VisualPun: He has fire powers, which show up in his appearance and hair when he's angry. He's a ''hothead''.
* VitriolicBestBuds: 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.
* VoiceOfTheLegion: 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.
* WeakButSkilled: {{Downplayed|Trope}}; 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.

[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/pony_head.png]]
->'''Voiced by''': Creator/JennySlate

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...

* ActionGirl: Pony Head has shown to be very effective in kicking butt.
* AdaptationalAttractiveness: 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.
* AffectionateNickname: Called "cupcake" by her father.
* AllThereInTheManual: ''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.
* AscendedExtra: Only appears in two episodes in the first season, but for the second and third seasons she's been upgraded to recurring character.
* BestFriend: 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.
* BigSisterBully: 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 [[CreepyMonotone 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.
* BullyingADragon: Ponyhead often gets herself into trouble by overestimating herself. The best example being when she stole dimensional scissors from Hekapoo.
* TheBusCameBack: 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.
* TheChainsOfCommanding: Pony Head left St. Olgas because the other princesses started to see her as their leader.
* CharacterDevelopment: 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.
* ChildhoodFriends: She and Star have known each other since they were toddlers.
* ClingyJealousGirl: Pony Head becomes jealous of Star hanging out with Marco. She even threatens to ''impale'' him and almost "[[BlatantLies accidentally]]" [[MakeItLookLikeAnAccident 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".
* ConsummateLiar: 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 HilarityEnsues.
* DefrostingIceQueen: 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".
* DeliberatelyBadExample: 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.
* ADogNamedDog: Played with; her real name is Lilacia, but [[DoNotCallMePaul 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".
* DoNotGoGentle: 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.
* EmbarrassingFirstName: Lilacia.
* EveryoneCallsHimBarkeep: 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".
* FireForgedFriends: Her dynamic with Marco in a nutshell.
* GreenEyedMonster:
** 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.
* HeroicComedicSociopath: 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 KoreanDrama 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.
* HeterosexualLifePartners: With Star; "Freeze Day" shows that the two have been friends since they were toddlers.
* HypocriticalHeartwarming: While Pony Head is happy to insult her sisters, she won't let anyone else do it, even Star.
* IChooseToStay: 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.
* InsistentTerminology: Even after she accepts Marco, she demands Star acknowledge him as her "best bestie ''on Earth''", as opposed to her "best bestie overall".
* InvisibleAnatomy: She's able to eat despite, by her own admission, having no stomach.
* ItsAllAboutMe: She does what she wants with very little concern for the wants and needs of others, with Star being the only (possible) exception.
* JerkassToOne: She's mainly a jerk towards Marco due the latter being dubbed as Star's other "BFF".
* JerkWithAHeartOfGold: 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.
* KarmaHoudini: 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.
* LastNameBasis: She's addressed by her family name. By her own insistence.
* ALighterShadeOfBlack: 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.
* MassiveNumberedSiblings: She has ''twelve'' younger sisters.
* ManipulativeBastard: "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.
* ProjectileSpell: Pony Head can shoot beams from her horn.
* ReallyGetsAround: [[DownplayedTrope 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''.
* RebelliousPrincess: Her father had a hard time controlling her, which is why she was sent to [[BoardingSchoolOfHorrors "St. Olga's Reform School for Wayward Princesses"]], where Miss Heinous promptly sucked the spirit out of her.
* ScrewThisImOuttaHere: 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.
* ShipperOnDeck: She "called it" that Star has a crush on Marco.
* StickyFingers: 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.
* VitriolicBestBuds: 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."

[[folder:Janna Ordonia]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/janna___girls_day_out_profile.png]]
[[caption-width-right:350:''"I know how to drop my pulse to zero, but only for sixty seconds."'']]
->'''Voiced by''': Creator/AbbyElliott

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.

* AffectionateNickname: Star calls her "Janna Banana" on occasion.
* AffectionatePickpocket: Pickpockets Marco for his house key while offering to "make some magic" with him via Star's book.
* AllThereInTheManual: ''Star and Marco's Guide to Mastering Every Dimension'' reveals that her last name is Ordonia.
* AllWomenAreLustful: 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 [[ItMakesSenseInContext he got cologne on his backside]], then sniffs the hand she spanked him with.
* AmbiguouslyBrown: 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.
* AscendedExtra: The character was originally created purely to serve as an obstacle for Marco to deal with in "Mewberty". [[https://youtu.be/7UbQPpioOV0?t=6916 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 ChekhovsGag in the final season.
* BreakoutCharacter: During the first season, Janna was a RecurringExtra who would be lucky to have more than two lines per episode. Her only relevant role in that season was in "[[Recap/StarVsTheForcesOfEvilS1E11Mewberty Mewberty]]", but even in that episode she disappeared at the middle of it. Strong fan reactions towards the character turned her quickly into an EnsembleDarkHorse 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.
* BunnyEarsLawyer: Despite being a NightmareFetishist and being somewhat unsettling when she teases Marco, she is a valuable ally and highly useful in some episodes.
* CelebCrush: She has one on Creator/JohnKeats.
* ChickenJoke: 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 AntiHumor punchline when telling this joke to Star.
* ComedicSpanking: 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.
* ADayInTheLimelight: "Girls' Day Out" featured her in a prominent role.
* DemonOfHumanOrigin: 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.
* DrearyHalfLiddedEyes: Janna is often seen with partially lidded eyes, fitting her devil-may-care attitude.
* EarlyBirdCameo: 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".
* EstablishingCharacterMoment:
** "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 [[NightmareFetishist desire for the titular arm to be her boyfriend]].
* FigureItOutYourself: 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.
* TheGadfly: 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".
* HiddenDepths:
** "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.
* ImprovisedWeapon: In "Bon Bon the Birthday Clown", she fends off Ludo's rats with a hairdryer.
* JerkassHasAPoint: 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.
* JerkWithAHeartOfGold: 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.
* LoveableRogue: She's a known troublemaker and she often teases Marco but it doesn't lessen her friendship with him.
* MagicSkirt: 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.
* NightmareFetishist: 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.
* NoodleIncident: 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.
* OddFriendship: 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.
* OOCIsSeriousBusiness: Janna is a well known NightmareFetishist. 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''.
** [[spoiler:Janna ''screams'' after Quirky Guy dies in front of her.]]
* OurSoulsAreDifferent: She split her soul in half in "Curse of the Blood Moon".
* OutOfFocus: {{Downplayed|Trope}} 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 [[PromotedToOpeningTitles 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.
* PerkyGoth: Is quite upbeat and cheerful, and also a lover of all things macabre.
* PlayingPossum: [[spoiler:In the GrandFinale, she reveals she can shut down her pulse for 60 seconds]].
* SecurityCling: Does this with Jackie in "Bon Bon the Birthday Clown", hiding behind her as she fends off rats.
* ShipperOnDeck: 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.
* StalkerWithACrush / StalkerWithoutACrush: 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.
* StalkingIsFunnyIfItIsFemaleAfterMale: Her behavior towards Marco is usually PlayedForLaughs. Star also sees Janna's behavior as innocent and non-vindictive.
* TheTease: Towards Marco.
-->'''Janna''': I think we all know who ''I'' have a crush on, don't we, Marco?\\
'''Marco''': Uh...\\
'''Janna''': [[BaitAndSwitch Eighteenth-century poet John Keats]].
* TheTeetotaler: 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.
* TokenEvilTeammate: 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.
* TomboyAndGirlyGirl: She is the Tomboy to Star's Girly Girl.
* TomboyishVoice: She's tomboyish and has a low-pitched, gravelly voice.
* TomboyWithAGirlyStreak: She's nowhere near as girly as the likes of [[GirlyBruiser Star]] ([[RealWomenDontWearDresses 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|MeansFeminine}}.
* {{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.
* VitriolicBestBuds: 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.
* VocalEvolution: 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.

[[folder:Kelly]]
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/s2e13_kelly_i_had_one_before.png]]
->'''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 PocketDimension.

* ActionGirl: She's a skilled sword user, and in fact has several of them.
* BloodKnight: 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.
* BlushSticker: Kelly's cheeks have permanent pink blushes on them.
* EmoTeen: After her final breakup with Tad she has random points where she sulks, becomes more sullen and emotionally sensitive.
* FriendsWithBenefits: 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.
* HammerspaceHair: As gigantic as her hair is, it is BiggerOnTheInside. 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.
* HopelessSuitor: 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 [[FriendsWithBenefits 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.
* HumanAliens: Kelly looks like a human but has mint-green hair, [[TheNoseless no nose]], and her hair is like an apartment/pocket dimension on the [[HammerspaceHair 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.
* InterspeciesRomance: Downplayed. She (a Woolett) and Marco (a human) become [[FriendsWithBenefits break up buddies]] before the latter breaks it off.
* NonStandardCharacterDesign: 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.
* TheNoseless: One of the indicators that she isn't quite human.
* PlanetOfCopyhats: "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.
* TheQuietOne: Doesn't talk much before revealing that Goblin Dogs are real. She's more vocal in her subsequent appearances.
* RelationshipRevolvingDoor: 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.
* RomanticFusion: 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.
* ShoutOut: Her face resembles that of [[Creator/{{Sanrio}} Kero Kero Keropi]], to an extent.
* SingleWomanSeeksGoodMan:
** 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 ShipTease with [[NiceGuy Marco]].
* ThrowingYourSwordAlwaysWorks: A tactic she uses against Meteora in "Divide".
-->'''Meteora:''' You could've put out someone's eye!
* TinyGuyHugeGirl: With Tad, as he is barely a foot tall while Kelly is average size for a teenage girl.
* TrademarkFavouriteFood: Goblin Dogs.
* WalkingTheEarth: Or in this case, travelling the multiverse is what Kelly does on a regular basis, fighting monsters and all.

* HumanAlien: Kelly looks like a human but has mint-green hair, [[TheNoseless no nose]], and her hair is like an apartment/pocket dimension on the [[HammerspaceHair 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.
