[[folder:Acerola Pualani]]
!! Acerola Gladiolus Chamomile Cyclamen Montblanc Wisteria Sunflower Zinnia Anemone Primrose Quartz Cherry Blossom Pualani the 13th.

The main character of the story. The last in a line of royalty who once ruled Alola, her ancestors' nagging, coupled with mishaps involving infinity energy, leads her into the Infinity Train.
----
* ThirteenIsUnlucky: As her name reveals, she's the 13th Acerola in her family, and not only is she basically a poor orphan, but she's constantly hounded by the ghosts of her ancestors into continuing a legacy she wants nothing to do with.
* AdaptationalAngstUpgrade: Acerola was fairly well adjusted in the anime and games despite her circumstances, but she's a lot more troubled here, primarily thanks to her ancestors and their nagging.
* AdaptationalBadass: This version of Acerola can use Aura, specifically ''Ghost'' Aura, when her canon counterpart has no such powers.
* AdaptationNameChange: Acerola had OnlyOneName in the source material, but here, not only does she have a proper full name, [[OverlyLongName but an outrageously long one at that]].
* AdaptationalPersonalityChange: [[DownplayedTrope Downplayed]] but still notable. Acerola acts mostly the same as in canon, but she has a slightly more cynical side brought thanks to her ancestors' nagging. She's also a bit more snarky.
* AdaptationRelationshipOverhaul: [[DownplayedTrope Downplayed]] between her and Ash. They're friends in both canon and this story, but while that's all they are in canon, this story's Acerola's implied to have a crush on him.
* AdaptationalSuperpowerChange: While she retains her ability to see and interact with the dead, she also gains the ability to come back from dying (somehow) and the ability to use Aura.
* AlwaysSomeoneBetter:
** In terms of Aura, she's this to Ash. She's proficient in Ghost Aura enough to not only see the dead, but also manipulate them to an extent, while the most Ash can do is sense the dead.
** During the Passage Fair, she becomes a [[DownplayedTrope Downplayed]] one to Princess Allie. While she's good enough to have a [[ThroneMadeOfX throne of plushies]] by the end of it, Acerola only does moderately well. Princess Allie just happens to be so much worse Acerola looks way better in comparison.
* AscendedExtra: She was just one of the many trainers/Trial Captains Ash met during the Alola season, but she's the main character here.
* AuthorityInNameOnly: Acerola's the last in the line of the original Alolan royal family, but given that the monarchy no longer exists by the present day, all this really gives Acerola is a bunch of washed-up ghosts pressuring her to continue the legacy.
* BackFromTheDead: There was an incident where she tried hugging a Bewear, and the Pokémon returned the hug so hard that ''it actually killed her''. Naturally, she's still around, [[UnexplainedRecovery and nobody knows how]].
* BadDreams: Implied; There's a specific Hypno among the ones in Aether House who's noted to specifically help Acerola asleep, like the other orphans with their bad dreams.
* BadPowersGoodPeople: Acerola's skill with Ghost Aura lets her, among other things, subjugate the souls of the departed, but she's a good person who only pulls out such a tactic when necessary.
* BerserkButton: Don't touch Mimikins. Acerola was willing to tolerate [[VillainousPrincess Princess Allie]]'s [[{{Jerkass}} attitude]] for most of her visit, but once she tries to take Mimikins as her own, Acerola snatches them away and ''slaps her''.
* BitchSlap: Delivers one of these to Princess Allie to get her to release Mimikins, and it's at that point that the hostilities begin between the two.
* BluntYes: This is her answer when Burnet asks her if she believes that [[IdiotHero Ash]] has yet to discover she's pregnant.
* TheChosenOne: [[ParodiedTrope Parodied]]. Lusamine goes on a big show on how Acerola, as the last heir of Alola, has been chosen to protect the Region from evil... All just to convince her to join her ragtag power rangers ripoff team.
* ColorMotif: Purple. Both her hair and eyes are purple, her [[SoulPower Ghost Aura]] takes the form of a dull shade of purple, and the dress she gets from Jewel is many different shades of purple.
* ContrastingReplacementCharacter: She and [[Fanfic/InfinityTrainBlossomingTrail Chloe Cerise]] could not be more different.
** Chloe is a SignificantGreenEyedRedhead who doubles as an OrdinaryHighSchoolStudent and daughter of a Pokémon Professor. Acerola is a purplette with matching purple eyes who's the last member of the royal family of Alola.
** Chloe doesn't have any powers until she gets on the Train, while Acerola has both Ghost Aura and her canon ISeeDeadPeople abilities.
** Chloe's a normal girl who gets called a "princess" as a sign of bullying, while Acerola is ''actually'' a princess, but has no real power or desire to get the power to use it.
** A heavy dislike of Pokémon is one of Chloe's defining traits, while Acerola doesn't seem to have a strong opinion on them.
** They both have a bad relationship with their family, but for different reasons: Chloe hates her father and mother for believing they don't care about her, while Acerola doesn't get along with her ancestors because they constantly pester her to continue the family legacy.
** Chloe becomes an EmpoweredBadassNormal with the items she gets on the Train, and makes a point to become a fighter without relying on Pokémon. Acerola, meanwhile, relies on Mimikins in their first actual fight, with her remaining in the sidelines as an ActionSurvivor.
** Their signature colors are complete opposites: Chloe's color is red which reflects her fiery spirit and passion, while Acerola gets purple to associate with her supernatural abilities and royalty. Moreover, Chloe's main outfit was her white beach dress, whereas Acerola wears a dark purple dress.
* DarkIsNotEvil: Wears purple and is associated with Ghost-types but she's a really sweet girl.
* DeadpanSnarker: She's got quite the dry wit, most of it directed at her ancestors.
* DidntThinkThisThrough: She tries to use Ghost Aura to stop her ancestors from bothering her again, while they're becoming more corporeal thanks to the infinity energy in Alola. It doesn't work.
* DidntSeeThatComing: Her ancestors doing a NoSell against her attempt to stop them with Ghost Aura leaves her stunned.
* FirstNameBasis: Most people just call her "Acerola" for the sake of simplicity.
* FloralThemeNaming: Most of, if not the entirety of her outrageously long name is named after flowers.
* FriendsAreChosenFamilyArent: She has a rocky relationship with her ancestors due to their nagging demands that she continues the family legacy, while on the flipside, she gets along just fine with the Alolan trainers, especially Ash.
* GracefulLadiesLikePurple: The dress that Jewel makes for her is all shades of purple.
* InnocentlyInsensitive: She unintentionally annoys Crumbs when she asks her if the food she served her is made of arts and crafts like the rest of the Lalaloopsy Land Car.
* TheGadfly: Retains this trait from canon. She answers Nanu's remark that he'll go abroad to stop Debbie by saying she'll unseal his will if he doesn't return, then teases Mallow about her crushes when the greenette tries to get Ash to talk about romance.
* GiantWaistRibbon: The new dress that Jewel makes for her is tied up with one of these.
* GoingCommando: Implied; when Lana instantly changes from her usual outfit to the swimsuit she wears underneath, Acerola mentally notes that the only thing she's wearing under her dress is her 'birthday suit', which is just another way to say she's naked.
* GoodIsNotSoft: Acerola is a kind girl, but if you get on her bad side, she'll pull no punches in punishing you: just ask her ancestors, who she tried to subjugate, or Furfrou, whom Mimikins made ''eat'' their own Charge Beam at Acerola's command.
* GracefulLoser: Unlike [[SoreLoser Princess Allie]], Acerola doesn't seem to get too upset when she loses, given she happily claps for the little Lalaloopsy after she wins the art game in the Passage Fair.
* ISeeDeadPeople: Retains this ability from canon, though she's BlessedWithSuck in this case, given the ghosts she interacts most frequently with are her pushy ancestors.
* LastOfHisKind: She's the last living descendant of the Alolan royal family, with the ghosts of her ancestors having quite the interest in having her continue it.
* LegacyCharacter: She's the 13th Pualani family member to hold the name "Acerola".
* LogicalWeakness: Her Ghost Aura lets her manipulate souls, but this is only the case for normal souls. When she tries to use her powers on her ancestors, who are becoming corporeal thanks to infinity energy, her attempt fails.
* NiceGirl: Don't get on her bad side, and Acerola will prove herself to be an amicable soul.
* NoBadassToHisValet: Her ancestors are an assortment of famous people who once ruled Alola, but Acerola herself holds nothing but contempt for them due to their constant pressuring her to continue the bloodline.
* OnlyChildSyndrome: While there are mentions of how Acerola's family is as fruitful as it's messed up, and it's ''very'' messed up, there's no indication that Acerola has any siblings that could take the throne for her, which only puts further pressure on her as her ancestors focus on egging her to continue the bloodline.
* OperaGloves: The dress Jewel makes for her has a pair of these.
* OverlyLongName: Her full name is "Acerola Gladiolus Chamomile Cyclamen Montblanc Wisteria Sunflower Zinnia Anemone Primrose Quartz Cherry Blossom Pualani the 13th."
* PrecisionFStrike: She calls Princess Allie an "asshole" when talking to Jewel about her.
* PrincessProtagonist: The main protagonist of the story, and a princess to boot, though the latter is mostly in name.
* RebelliousPrincess: Again, she's a princess mostly in name, but she refuses to follow her ancestors' orders to continue the royal family legacy.
* RelatedInTheAdaptation: The fact that "Montblanc" is in her name implies she's somehow related to Lusamine's family, of which she has no connection in canon.
* SecretKeeper: She promises Burnet to keep her pregnancy a secret from Ash, though she almost flubs it out while visiting the Aether Foundation.
* SoulPower: Not only is she a Ghost Type Trainer like in canon, but her Aura powers are stated to be ''Ghost'' Aura.
* StrongFamilyResemblance: According to the narration, barring a few minor differences, Acerola looks pretty similar to the previous queens of Alola.
* SupernaturalIsPurple: She wears purple, uses Ghost-types, sees the spirits of her ancestors and uses Ghost Aura.
* SympathyForTheDevil: Very [[DownplayedTrope Downplayed]] as Lucy has gone from evil to neutral, but Acerola still can't help but feel a little sorry for her after she tells her how The Apex were destroyed.
* VerbalBackspace: She comes ''this'' close to spoiling Burnet's pregnancy to Ash, the only person still not aware of it, until she backpedals and says Burnet's tired from the ''preparations'' for the ancestors festival.
* WhiteSheep: From what we've seen of her family, most of them are racist, jerks, or racist jerks. Acerola herself, however, is a NiceGirl with only a mischievous streak.
[[/folder]]

[[folder:Mimikins]]
!! Mimikins
The ghost of a shiny Mimikyuu who accompanies Acerola.
----
* ActionGirl: Acerola reveals Mimikins to be female in chapter 4, and she's very capable of kicking butt when needed.
* CastingAShadow: Knows Shadow Claw, which she puts to good use against Furfrou.
* DarkIsNotEvil: Mimikins is the ghost of a deceased Mimikyu who knows Shadow Claw, but is loyal to Acerola.
* ADogNamedDog: [[SubvertedTrope Subverted]]. Despite this being the norm for most Pokémon, this Mimikyu has been given the name of "Mimikins" by Acerola.
* TheFairFolk: Partially a Fairy Type.
* FriendlyGhost: As long as you're friendly with Acerola, she'll be good with you too.
* SoulPower: Her other typing is Ghost, which is doubly notable given that she's the literal ghost of a deceased Mimikyu.
* UndyingLoyalty: She's technically already dead, but she's still pretty loyal to Acerola.
[[/folder]]

[[folder:Lucy]]
!! Lucy
The last surviving member of The Apex, whom Acerola encounters at the Giant Apple Car.
----
* AdaptationalAngstUpgrade: Not only does she retain the canonical connection with The Apex, but has been through not one, but ''two'' traumatic events: the first left her with nightmares, the second pretty much left her with nobody left by her side.
* AdaptationalSympathy: Lucy isn't given that much sympathy in the ''Blossomverse'', given she's an Apex member, but this story has Acerola pity her after explaining her backstory.
* AscendedExtra: From a fairly minor Apex member to the ''sole survivor'' and one of Acerola's travelling companions.
* TheAtoner: Decides to become this when Acerola offers her to join her team.
* BackstoryHorror: Most of the trauma she experienced, from Trip's LastStand to the massacre at The Green Light Red Light Car, happened in her backstory before we meet her proper.
* BrokenBird: Being in the company of The Apex alongside two traumatic events have left Lucy with a downbeat, pessimistic attitude.
* DarkAndTroubledPast: She got snatched by the Train at some point, and was recruited into The Apex sometime later. From there, half the people she had met would be taken out by Trip and his Pokémon, giving her a fear of the creatures, while the rest would be utterly slaughtered at The Green Light Red Light Car by the machinations of none other than The Conductor, whom they worshipped.
* DeerInTheHeadlights: The only reason she's alive. She was paralyzed with fear once Grace and Simon were killed by gunshots at The Green Light Red Light Car, leaving her as the only Apex member to not move during their FreakOut, and consequently, the only one not shot down in the ensuing chaos.
* DissonantSerenity: She recalls the events that ended with The Apex being wiped out rather casually while eating a giant apple.
* FemaleMonsterSurprise: She's a little shocked to hear that Mimikins is a girl.
* HarmfulToMinors: Not only is she stuck in an interdimensional train where it's impossible to escape, with her only companions being a cult worshipping The Conductor, but then she gets stuck in not one, but ''two'' heavily traumatic events, the second one ending with her completely alone.
* HatesBeingAlone: Says as much about herself when Acerola asks her to join her team, and given she was alone from after The Apex were killed off until Acerola arrived at The Giant Apple Car, it's safe to say that hasn't helped at all.
* GrowlingGut: Her stomach begins to growl in hunger shortly after saying she's not hungry.
* LastOfHisKind: She's pretty much the last member of The Apex on the train, as Drogo Denver was sent back home through the Zero Cannon.
* [[MrExposition Miss Exposition]]: She tells Acerola about not only the event that ended in The Apex's destruction, but the events leading ''to'' said event, all while eating a giant apple.
* SoleSurvivor: She's the only member of The Apex to survive the slaughter in The Green Light Red Light Car, which The Conductor takes notice of.
* TooUnhappyToBeHungry: [[SubvertedTrope Subverted]]. She first tries to deny Acerola's request to eat the giant apple with her, but her GrowlingGut is quick to say otherwise.

! Marinette's Team

[[folder:Marinette Dupain-Cheng]]
!! Marinette Dupain-Cheng / Ladybug
A parisian teenager who also happens to be the superheroine Ladybug. An encounter with Apex Conductor sends her to the Train, kicking off the events of ''Akuma Numerology''.
----
* AbominationAccusationAttack: Once she transforms into Ladybug to fight The Miller Knight, the audience constantly call her a witch.
* ActionGirl: She's Ladybug, after all, which she shows to The Miller Knight for their fight.
* AdaptationalAngstUpgrade: She's currently trapped in an interdimensional therapy train where she can't leave alive until her number gets to zero.
* AnAxeToGrind: Hornwood gives her and Tikki his axe in order to harvest a green thread tree.
* AscendedExtra: In most Blossomverse-like stories, Marinette is mostly treated as a fictional character who, while confirmed to ''exist'' as her real self in the multiverse, is never seen. She appears in person for the first time in Crown of Thorns and gets her own story in Numerology.
* ChronicHeroSyndrome: Pretty much the reason she's on the Train. Apex Conductor topples down a building and threatens civilians to prompt her to save them, making her a sitting duck for Apex Conductor's attack.
* CombatPragmatism: She throws lemonade at The Miller Knight's eyes to disorient him, then uses her yo-yo to wrap him up.
* FusionDance: She uses Unification to unify the Ladybug and Turtle Miraculous, though we don't get to see the resulting superheroine.
* GratuitousFrench: [[AvertedTrope Averted]], since she's actually French. She and The Cat talk to each other in French once the feline Denizen realizes Marinette feels more comfortable speaking in her native language.
* HappyPlace: She goes into her own to concentrate on sewing the green threads on her dolls. The only thing we know about it is that it has no axes.
* HeroOfAnotherStory: Specifically of ''Numerology''.
* InformedAttribute: The Cat mentally notes that while Marinette can speak English, it's not perfect and feels more comfortable speaking in her native language. You wouldn't know this reading ''Akuma Numerology'', where she speaks English just fine.
* KillerYoYo: Her main weapon. She uses it to keep a building from toppling during Apex Conductor's attack, and then uses it to wrap The Miller Knight and keep him from moving.
* LockedInTheDungeon: This is what happens to her after [[ItMakesSenseInContext she fails to give The Milly King his favorite beer]].
* MundaneUtility: She unifies the Ladybug and Turtle Miraculous to... Use the latter's shield to deliver some dolls back to her world.
* MythologyGag: Her number at the start of the story is 91, which represents the episode number of the last canonical episode before the events of the story (Optigami).
* RageBreakingPoint: Finding the green thread tree she and Tikki have been looking ''for hours'' prompts her to swing her axe and harvest it with extreme prejudice.
* TextileWorkIsFeminine: She sewed dozens of dolls of her train-napped friends before meeting The Cat, and even sends some of them to Rena Rogue.
* ThisIsGonnaSuck: Correctly guesses that the Giant Apple Car is going to be terrible to complete.

The owner of the local cafe at the Lalaloopsy Land Car.

* [[MrExposition Miss Exposition]]: While Jewel explains how the Train works to Acerola, Crumbs is the one to explain its equivalent of ghosts, Soul Denizens, and how they work.
* RoseHairedSweetie: Her hair's a darker shade than Jewel's, but she's every bit as nice as her.
* SweetBaker: She's a nice girl who owns a cafe in the Lalaloopsy Land Car.
* YouRemindMeOfX: Her being the main worker and owner of her own cafe, alongside being a SweetBaker, reminds Acerola of Mallow.

* {{Omniglot}}: She can speak both English and French, the latter coming in hand when she meets Marinette.

! Passengers

[[folder:Princess Allie]]
!! Princess Allie
A princess from Parfum Palace, in Kalos, and the first Passenger that Acerola meets.
----
* AdaptationalVillainy: Princess Allie was a jerk in canon, sure, but she never went as far as to ''attack a festival full of innocent people''.
* AlphaBitch: Certainly acts the part, constantly boasting about how great she is and how everybody's beneath her.
* AndCallHimGeorge: She comes ''this'' close to taking Mimikins away for herself before Acerola arrives and slaps her for her trouble.
* BerserkButton:
** Ash Ketchum in general gets her riled up. Acerola merely mentioning him causes her to grow visibly hostile.
** Don't take away what she believes is hers. Ash allegedly doing this got on her bad side, and Acerola snatching Mimikins from her marks the point where both princesses become hostile towards each other.
** [[SoreLoser Losing]]. Even losing to a washed up has been in a relatively lowkey attraction gets her so riled up ''she decides to destroy everything''.
* BitchInSheepsClothing: She doesn't seem that Bad when she first appears. Unbelievably arrogant for sure, but otherwise normal. Then she reveals her '''''5000+''''' number, calls out Acerola's lack of a RoyalRequisiteRegalia, and ''tries to snatch Mimikins away'', and it becomes clear she's not a very nice person.
* DeathGlare: Gives one of these to Acerola after she slaps her, and then gives an even more intense one when she snaps after losing to Acerola on the Passage Fair.
* EpicFail: It's almost comical how bad she does in the Passage Fair; even without comparing her to Acerola, she fails to land a ring on the ring toss, makes a bunch of scribbles that doesn't resemble the doll she's painting at all, and her attempt at apple bobbing ends with her ''with a fish on her head''.
* FieryRedhead: She has reddish-pink hair, and is quite energetic and emotional.
* {{Jerkass}}: At her absolute worst, she's a haughty and nasty piece of work who sees herself as above everybody else and will snap if this notion is challenged.
* PrecisionFStrike: Yells "damn you!" at Acerola during her RageBreakingPoint.
* RageBreakingPoint: Being defeated by Acerola, who she sees as nothing but a washed up has been from a long gone monarchy, marks the point where she ''explodes'' and tries to have Furfrou destroy everything.
* RageQuit: With Furfrou defeated and Acerola more than ready to have Mimikins attack ''her'' if she doesn't back away, Princess Allie leaves the Car incensed, promising Acerola that they'll meet again before leaving.
* RedheadsAreUncool: She's a redheaded RoyalBrat who can act nice, but will just as swiftly drop the pretenses to reveal the condescending jerk she truly is.
* TheReasonYouSuckSpeech: Gives one to Acerola over how, despite claiming to be a princess, she's pretty much got nothing to show for it.
* RoseHairedSweetie: [[AvertedTrope Nope]]; she's actually quite a jerk.
* SelectiveObliviousness:
** Among the things she tells Acerola that Ash did to her, she mentions him stealing her Pikachu and her boyfriend Clemont, conveniently omitting the fact that the Pikachu was actually ''Ash's'' and Clemont wasn't actually her boyfriend, she just took him as her boyfriend due to a misunderstanding.
** Shortly after trying to have Furfrou destroy the Passage Fair with a barrage of Charge Beams, she scolds Acerola when she has Mimikins knock the Pokémon out in order to stop their rampage.
* SmallNameBigEgo: Her 'kingdom' isn't nearly as impressive as she makes it out to be, on or off the train.
* SoreLoser: She gets so enraged at losing the Passage Fair against Acerola that she has Furfrou ''unleash a BeamSpam at the fair'' as revenge.
* StarterVillain: She's the first antagonistic person that Acerola encounters on the Train.
* VillainousPrincess: She's a haughty princess from Kalos who's such a sore loser she ''has Furfrou BeamSpam everybody at the Passage Fair'' for revenge.
* WeWillMeetAgain: Yells this to Acerola before fleeing the Lalaloopsy Land Car after her Furfrou is taken out.

[[folder:The Conductor ('''Spoilers''')]]
!! The Conductor / Amelia Hughes
The Conductor of the Infinity Train, an oddly mechanical humanoid with a red wavelength on their face.

In reality, she's Amelia Hughes, a Passenger from a long time ago who rides a large mecha in order to act as The Conductor.
----
* ActuallyIAmHim: When a group of Denizens come to deliver the busted Zero Cannon to The Conductor and ask where he is, she matter-of-factly tells them they're seeing her, and they connect the dots from there.
* AdaptationalEarlyAppearance: [[DownplayedTrope Downplayed]], since she was present in Book 1, but while it took a few episodes for her to appear in person, in here she appears in what's the equivalent of the ''start'' of the show.
* AdaptationalVillainy: She sends The Apex onto a death trap where they get gunned down, giving her a bigger (explicit) body count than in the canon series.
* BadGuysDoTheDirtyWork: She's ultimately responsible for the end of The Apex, taking them to The Green Light Red Light Car where events unfold to eradicate them.
* BigBad: Implied, given the story takes place during Book 1.
* HiddenAgendaVillain: She wants to do something with the Zero Cannon, but besides it being about "preparing for loose ends" we don't know what that is. Same with her desire to get the Ladybug and Cat Miraculous.
* GreaterScopeVillain: She's the main reason why The Apex exists, as an encounter with Grace Monroe
* SamusIsAGirl: Despite initially looking like a massive robot, that's just a mechanical suit; the ''real'' conductor is a woman named Amelia Hughes.
* StealthyColossus: They're a pretty big hunk of metal, and yet they somehow manage to enter The Cat's shop without her noticing.

* DeathByAdaptation: Most of them were still alive by ''Blossoming Trail'', but they're all dead here.
* DiesDifferentlyInTheAdaptation: Simon was killed by a Ghom in canon, while here [[spoiler: he gets gunned down by The Doll.]]
* HeroKiller: They killed both Trip and Lexi, the former definitely, the latter allegedly.
* InfantImmortality: [[AvertedTrope Averted]]. Most of The Apex was composed of children, but they weren't spared from whatever killed them all.
* KarmicDeath: Assuming the diary entry is being literal and not meraphorical, then half of the Apex met their end by Trip like their victims: being thrown to the wheels.
* KilledOffscreen: By the time they're brought up, something has happened that has outright killed all of them, Grace and Simon included. [[spoiler:From a diary entry, it was said that Trip killed off many of them in a LastStand, but something else had finished the job later.]]

Luckily for her, everybody's pretty understanding when she spills the beans.

* ThePowerOfHate: The sheer hatred he holds for everybody, that carries over from Drogo Denver, empowers him into one of the strongest Akumatized Villains that Team Miraculous have ever faced.
* PurpleIsSupernatural: Those hit by his attacks get a purple glowing number on their palm, rather than the more common green numbers.
* RequiredSecondaryPowers: His power is pretty crazy, but it wouldn't be nearly as effective if it didn't have a passive MindRape element to make people more susceptible to being snatched by the Train.
