[[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 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.
* 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".
* 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]] [[BecomingTheMask 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.
* 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.
* HiddenDepths:
** 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.
* MixedAncestry: His mother is a demon and his father appears to be a Mewman.
* 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.
* PersonalityPowers: 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.
* 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.
* RealityEnsues: 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.
* 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.
* 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.
* 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 [[RealityEnsues 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.
* YouGottaHaveBlueHair: Tom has pink hair.

[[folder:Flying Princess (Lilacia) Pony Head]]
[[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...
----

->'''Voiced by''': Rider Strong

* AmbiguouslyBrown: She has dark skin with [[YouGottaHaveBlueHair mint-green hair]], but her ethnicity is unknown since she isn't a human.

* OnlyChildSyndrome:
** Star is the only child of the King and Queen of Mewni.
** {{Subverted|Trope}} with Marco, like Star, he was an only child until his mother got pregnant in "[[Recap/StarVsTheForcesOfEvilS3E32MarcoJr Marco Jr]]".

* StupidSexyFriend: 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.

* 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. [[GettingCrapPastTheRadar 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.

* FrickinLaserBeams: Pony Head can shoot beams from her horn.

* TheTrickster: She is shown to be a rather mischievous person. Her favorite victim is Marco but she enjoys playing with others like Star as well.

* YourCheatingHeart:
** 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.

* BashSiblings: They are best friends and both love to kick monster butt together, though this starts to move into BattleCouple territory as they develop feelings for each other.

* ReallyGetsAround: [[DownplayedTrope 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 ''[[AnythingThatMoves sentient pigeon]]''.

* VitriolicBestBuds: 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.

* 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 loud out that they're friends.

* 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 "Coronation", 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 "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.

->'''Voiced by''': Creator/GreyDeLisle (season 1), Creator/AbbyElliott (season 2 onward)

* 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 proteciton since [[MundaneSolution Meteora just punches him out instead]] after getting tired of trying to drain all his souls.

* 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. He gradually starts to take responsibility though.
