The Professor Layton franchise has a huge and quirky cast. Surely it needs one of these pages, right? Currently under construction, but feel free to contribute.Note: This series has Loads and Loads of Characters if you include every single villager, so let's just stick to the main cast.
open/close all folders
Hershel Layton (Theodore Bronev)
"A true gentleman..."
The protagonist. A gentlemanly archaeologist famous for his puzzle-solving skills.
Actual Pacifist: He eschews violence, considering it to be ungentlemanly, and will only get into a fight if it's absolutely necessary. And when he does fight, he fights to disarm, never to injure or kill.
Cool Car: The Laytonmobile; in Curious Village he freely admits that "I adore the contraption." Its coolness gets cranked Up to Eleventhanks to Don Paolo's modifications in Unwound Future.
Cool Teacher: Even outside the world of his cases, he's well-respected by the Gressenheller faculty and students (some with even more than just respect). In Last Specter it's clarified that at the age of 27, he became the youngest professor ever to join the Gressenheller staff.
Cry Cute: The fangirls had a field day with this one...
Doting Parent: He has shades of this with Flora. Most noticeably, he has a particular voice inflection that seems to be reserved solely for when he's speaking to her; it's softer and gentler than his regular voice (which is already quite placid and easy on the ears).
Expy: Akihiro Hino from Level 5 revealed that he's actually a clever Phoenix Wright expy.
Hino: From the outset, Professor Layton owed a lot to Phoenix Wright in some ways. We researched the good and bad points of Phoenix Wright, developed the good points and overcame what I saw as the bad points - that's how we created Professor Layton.
Geek Physiques: His coat and hat somewhat hide the fact that he's basically a pipe-cleaner man with a pumpkin for a head. Less severe in the official art, but some cutscenes give him really, really bony arms. Of course, those same cutscenes make it quite clear is not exactly out of shape.
It's implied in Curious Village that he does take it off to sleep, though.
Out-of-Character Moment: He breaks his gentleman code several times throughout the events of Unwound Future, including breaking a promise to Flora that he would take her with them on the investigation and hitting a young Klaus/Clive after the explosion that killed his parents. And then he cries at the end.
Papa Wolf: Unwound Future in particular puts him in this light. Do not mess with Luke Triton or Flora Reinhold. He will defy the laws of physics if that's what it takes to make you pay for it.
Stiff Upper Lip: For all the weirdness and dangerous situations that get thrown his way, Layton never loses his composure. The ending of Unwound Future is one of the few times Layton's Stiff Upper Lip falters.
Tranquil Fury: Seen only in Unwound Future, when circumstances put him in Papa Wolf mode; his expression darkens (look at his eyes) and his voice takes on a harsh edge, but he doesn't properly let loose with the anger he's obviously feeling.
Unknown Rival: Has one in Don Paolo. It's revealed in Unwound Future how their feud began.
Luke: "Professor, what did you do to Don Paolo? Why does he want to get revenge on you?"
Layton: "I haven't the slightest idea, Luke."
There are tiny hints dropped from game-to-game. Another hint is dropped in the second. From Don Paolo's point of view, Layton took a LOT from Don Paolo - his teacher, his praise, the girl he loved. And Layton is TOTALLY OBLIVIOUS.
"Apprentice Number One!"
The professor's apprentice. Aspires to be a gentleman when he's older.
Big Brother Instinct: He behaves like this toward Flora in the second and third games, despite being very obviously younger than she is. Justified in that he's known the Professor longer and has more investigative experience, while she's new at pretty much everything in the world.
Big Eater: In Diabolical Box, it's noted that Luke orders twice as much food as Layton in the train's dining car. And in Unwound Future, Flora remarks that he always seems to order half the menu whenever they dine out.
Nice Hat: It's stated in one of the Curious Village meta-puzzles that he never takes it off.
Pink Girl, Blue Boy: While Flora wears a fair bit of pink, Luke's signature color is very much blue.
Speaks Fluent Animal: The English version of Curious Village presents it as Friend to All Living Things, though, and an Informed Ability at that (when he tries to coax a cat to him, he ends up getting scratched). The other games, however, use the trope perfectly straight — Luke's ability to communicate with animals comes in handy in both Diabolical Box and Unwound Future, and Last Specter shows that he's been able to do it for years.
There actually may be a reason to why Luke couldn't communicate with Claudia. The cat is probably a robot, like the rest of the residents of St. Mystere.
The Hermit: Somewhat in The Last Spectre as he stays in his room, refusing to let Layton and Emmy in until they solve his door puzzle. He even refuses to talk to Clark.
The Cat Came Back: Despite his best efforts to leave her at home and out of danger, Layton just can't convince her to stay there. Somewhat justified by an apparent case of separation anxiety; she gets frightened if she doesn't know where he is.
Cool Big Sis: Luke regards her as an honorary one of these. In Diabolical Box, they appear to have grown very fond of one another; they have a great time together at the fair in Dropstone, and Luke is very upset when he realizes she's been kidnapped. They squabble more in Unwound Future, but it's also very clear that they care about each other quite a bit.
Daddy's Girl: To her own father before his death, and then later she essentially becomes this to Layton.
While it's never made clear if she was legally adopted, Baron Reinhold did entrust guardianship over Flora to whoever solved the mystery of the Golden Apple... and that was the professor. And considering that adorable laugh of hers when she hugged Hershel in Curious Village, it's safe to say she's pretty happy to be with the Layton crew.
Their brief but emotional reunion when she throws herself into his arms after her abduction in Unwound Future would also suggest this.
Heartwarming Orphan: Despite being older than most examples and adopted for a change she is almost always one of these in the games she's in.
The Ingenue: A very innocent (and adorable) young lady, to the point Luke can seem more worldly and mature than she is despite being younger.
Lethal Chef: The credits of Curious Village and Unwound Future make it pretty clear that Flora cannot cook.
The Pollyanna: Despite her past she is a very determine and positive young lady.
Pretty in Mink: The half-cape she wears in Diabolical Box appears to have some sort of fur trim.
Royal Blood: She's the daughter of a baron, and thus part of the nobility. This actually has relevance to the plot of Professor Layton's London Life.
Spoiled Sweet: She doesn't seem to have a malicious bone in her body, and on those occasions when she actually does get mad, it's not hard to soothe her.
The Unfavorite: It's understandable that Layton doesn't want to bring a young lady into danger (and even if you think that's a bit sexist, you have to admit that Flora is in no way equipped to handle such situations), and he'll go to her aid when she is in danger; but the fact is that when she's not physically present, she might as well not exist. It's even worse when you consider that Flora is quite sensitive to being left behind — a common fan theory is that because of her weird background, she has monophobia and/or separation anxiety. Compare this to the other kid that Layton looks after, who gets to tag along everywhere as his sidekick. A couple of really bad examples on this front:
In Diabolical BoxLuke and Layton realize that the "Flora" they've been traveling with was really Don Paolo, who had left Flora behind at a previous stop and, content that she's safe, go on their merry way (they were right, but had no way of knowing for sure). Then again the train was stopped at the station, and all of the crew was exploring Folsense instead of preparing to start it up again. So were stuck in that town.
In Unwound Future she's upset at being left out again and makes Layton promise to bring her along. Rather than keeping the promise, or at least explaining to her why he's breaking it, Layton does a rather un-gentlemanly thing and ducks out the back while she's out of the room. Later on, she hears about Future Luke and Future Layton, and asks what her future self is up to. (Present) Luke and Layton have to admit that the thought of Future Flora never crossed their minds.
Vague Age: It's not really made clear how old Flora is. She's older than Luke (whose age is confirmed to be ten in Last Specter, and thus twelve or thirteen by the time of Curious Village), but still young enough to require a guardian, and it is stated that the events of the first game don't happen until she's "out of childhood." Most players estimate her to be between fourteen and seventeen.
Why Did It Have to Be Snakes?: She seems to have an intense fear of being left alone. It gets the Woobie treatment in Diabolical Box, but Unwound Future makes it seem more like a Berserk Button. (Maybe she thought they should have caught on by then that she's afraid to be alone.)
Windows to the Soul: She has easily the largest eyes of anyone in the cast, ostensibly to further illustrate how sweet and innocent she is.
Layton's first assistant, who accompanies him on the adventures of the prequel trilogy and knew the Professor even before Luke. After being saved from the police by the professor, Emmy hoped to return the favor somehow. Her wish is fulfilled some years later when, in The Last Specter, she's assigned to be Layton's assistant by the dean of Gressenheller University. Layton doesn't really remember her, but apparently she doesn't mind. At the end of the prequel trilogy, it's revealed at the very end that she is Layton's cousin through his biological father Leon Bronev.
Action Girl: Boy howdy; she could chase after the Black Raven and jump from rooftop to rooftop.
The Apprentice: Though not to the same extent as Luke, Emmy does take lessons from the professor in observation and puzzle-solving.
Ascended Fanboy/The Team Wannabe: More Sidekick than Team, though. Emmy seems to have something of an obsession with Layton, and even uses the word 'Laytonesque'. This was before he was famous. It's implied that she's done a lot to get the job as Layton's assistant.
Given her role as The Mole, this is pretty justified.
Badass Adorable: She's a bright, curious young woman who's also probably the best hand-to-hand fighter in the series.
Becoming the Mask: Despite working as Layton's assistant under Bronev's orders, she grew to genuinely like her adventures with Layton and Luke, and formed a true friendship with them. This is partially why she decides to quit after everything is concluded: she feels guilty and ashamed for betraying them.
But Now I Must Go: Unsurprisingly, since she doesn't appear in the original trilogy. She quits her job as Layton's assistant not only because her mission as a Targent agent is over, but also (and seemingly more) out of guilt and shame over her betrayal; though she is still on good terms with Layton and Luke.
Eaglelander: Invoked. One character in The Last Specter describes her as a British woman having an "American attitude".
Flat "What.": Her facial expressions just scream this from time to time, especially when snarking about Inspector Grosky.
Groin Attack: Does this to one of Descole's mooks in Eternal Diva.
Heel-Face Turn: Double subverted. She first appears to be, and is, on the good guys' side, but then it is revealed she was a spy for Targent all along. However, even then, she is not evil, and even though she betrayed Layton and Luke, you can tell she wasn't happy about it, and it's heavily implied, if not outright stated, that she worked under Bronev to snap him out of his obsession over the Azran Legacy. She also redeemed herself by helping to stop the Azran golems.
Hypercompetent Sidekick: Not that Layton is incompetent, unlike most other examples of the trope, but she's still extremely intelligent.
Leeroy Jenkins: Of a sort; her first answer to most every hurdle is a good roundhouse kick.
The Mole: She's actually a spy for Targent, and describes Bronev as family to her after all he's done for her.
The Southpaw: Though it might be a result of what direction her sprite faces, most of Emmy's gesticulations and writing in her notebook are done with her left hand. However when faced from the front, she does point with her left hand, where Luke and Layton point with their right.
Supreme Chef: A scene in the credits of Last Specter shows her cooking a meal for Rosa and Layton, both enjoying the meal.
Took a Level in Badass: An episode reveals her with her hair shorter and her trying to figure out how to prove she didn't steal a wallet. Flash forward a few years, and now we see her kicking ass, jumping onto rooftops and punching thugs in the gut.
"What?! That's absurd! You'll need more than some daft charge to save your hide!"
An infamous (among criminals, that is), grumpy detective from Scotland Yard. He doesn't always live up to his reputation, though.
The Cameo: In The Last Specter, he and Barton appear briefly, and only Emmy encounters them.
He makes another quick appearance in Azran Legacyhaving just married Grosky's sister!
Expy: Of Inspector Japp from Poirot, another large, bossy Scotland Yard inspector with an irritable cockney bark and a splendid moustache. It's downplayed, though, given that Chelmy acts like a pettier, more selfish caricature of Japp.
Hidden Depths: An episode in Last Specter reveals that when he was a constable years ago, the current inspector and he were on a case that would promote Chelmey to an inspector. However, Chelmey rushed ahead to arrest the crook, leading his boss to take the bullet for him. This makes him dedicated to his job, but also taught him to take time for himself.
Informed Ability: He's implied to be one of the greatest policemen Scotland Yard has to offer, but every single conclusion he ever draws at any point in-game is consistently wrong.
Jerk with a Heart of Gold: He loves his wife's homemade sweet potato fritters more than anything, and is supposedly a very devoted husband. He's also very fond of his bumbling sidekick and admits privately to Layton that he protects him from receiving formal reprimands that would otherwise cost him his job.
The Real Remington Steele: The Chelmey in Curious Village is Don Paolo in disguise; the real Chelmey doesn't appear until game 2.
Small Name, Big Ego: To be fair, he IS going up against Professor Hershel Layton. If he was going up against any other detective, he'd fare better.
Sweet Tooth: His wife's homemade sweet potato fritters are what he eats after every arrest. This is very important in Curious Village.
Wrong Genre Savvy: Acts like he's the hero of the mystery stories, not the Arrogant Cop Who Jumps To Wrong Conclusions.
Chelmey's Sidekick from the second game onwards. Not much is learned about him until Unwound Future.
Badass: He ran all the way from Scotland Yard to Misthallery (and back) which takes Emmy at least ten hours on her scooter, and when pushed into shark-infested waters, he decides to go for a swim, not minding the fact that he could be eaten alive.
Friend on the Force: Was this to both Layton and Emmy separately, even before they met each other. Where Chelmey was cranky and resented civilians butting in, Grosky is quite friendly and quick to help out.
Hot-Blooded: When he hears there's a criminal to track down, he's often off and running before he bothers to hear the details.
Expository Hairstyle Change/Expressive Hair: In a flashback in Lost/Unwound Future, when he sees Claire, the object of his affections, giving a love letter to Layton and kissing him. It goes from relatively normal to the "horns" he has in the present day.
Giant Space Flea from Nowhere: In the first game, he's this in-universe for Layton, who has no idea why this guy showed up out of nowhere to try to kill/frame him. He also pulls this trope in a more straightforward manner at the end of the first game when he shows up out of nowhere in a flying machine with wrecking balls to try to bring down the tower on Layton and the Golden Apple that he ostensibly in town to beat Layton to. This comes completely out of the blue, considering your encounters to this point give no impression that this is the kind of thing he'd pull.
Heel-Face Turn: In Unwound Future, he helps the heroes near the end because he wanted to know the truth about Claire's death as much as anyone - plus, there was an even more dangerous villain that had to be stopped. Without him, our heroes would have met their demise.
In Eternal Diva, he dressed briefly as an elderly woman half his size.
Jean Descole (Hershel Bronev)
"As expected from you, Layton."
The antagonist in the second trilogy, as well as in Eternal Diva. He's a masked man who creates machines for his evil purposes and likes to "play games" with his victims. No one knows his real identity.
Affably Evil: Pretty much through 85% of Azran Legacy as Professor Sycamore, who's so affable and sociable to Adorkable levels.
Hidden Depths: As he stated himself, he once had a wife and daughter, and thought he could get over his desire for revenge and turn his life over. But when said wife and daughter died, he lost all hope of turning over a new leaf, and focused solely on his quest for revenge, not caring about anything else. Aurora also states that there might be some good left in Descole which he isn't seeing.
I Have Your Wife: Kidnaps Luke's mother and poses as his butler in order to get his father to do what he wants.
This strange character appears in the first three games, but has no relevance to the plot. He tells you about hint coins in the first two games, and gets angry when he finds out someone beat him to the punch in the third.
Berserk Button: When Layton finds out about game mechanics from someone else.
Have We Met?: He always acts like it's the first time he's met you when you find him in game.
Doomed by Canon: Canonically, Layton and Luke first meet her in Curious Village, which throws a wrench into her appearing in the prequels. Subverted since she manages to show up anyway: Last Specter and Azran Legacy get around this by having her meet Emmy and set up Keats as her stand-in, then leave before the boys enter the scene. In Miracle Mask, she wears a Paper-Thin Disguise and calls herself "Nanny Grams" ("Elizabeth" in the British version).
Have We Met?: When she meets Layton and Luke in Diabolical Box and Unwound Future, she acts as though she's never seen them before, even though they recognize her right away.
Your Tomcat Is Pregnant: According to the in-game profiles, Claudia is actually male. Interestingly enough, the cat that looks exactly like Claudia in the third picture book of Lost/Unwound Future is female.
Impossibly Cool Wealth: To the point he uses it as a hidden treasure for puzzlers to find as part of a way to find out who is best suited to taking care of Flora and providing them with the means to do so after he died.
Well-Intentioned Extremist: Most people have legal documentation which settles matters like who will be the guardian of their minor children. This guy thought it was more practical to build an entire village of Ridiculously Human Robots to take care of his.
The butler of the Reinhold mansion.
The Butler Did It: Aversion. Matthew is probably the single most helpful resident of the entire village as far as Layton's investigation goes.
A somewhat snide individual, he identifies himself as Baron Reinhold's nephew. His murder is what prompts the arrival of Inspector Chelmey in St. Mystere.
A mysterious old man who kidnaps the villagers and lives in the tower.
Gadgeteer Genius: Except for Flora and Granny Riddleton, he BUILT all the residents of St. Mystere.
Old Retainer: More or less; the pages from his journal, which are found here and there throughout the village, indicate that he sees himself as this. Being the only adult human in all of St. Mystere, he has to maintain the robotic residents and look after Flora until someone solves the puzzles and becomes her new guardian. Presumably, he continues maintaining the village after the events of the game.
Characters in Diabolical Box
Dr. Andrew Schrader
The Professor's good friend and mentor.
Bunny-Ears Lawyer: Brilliant, but somewhat eccentric to judge by the contents of his apartment.
Disney Death: The gas in the Elysian Box didn't kill him, it just sent him into a deep coma.
Dying Clue: The letter he sends to Layton to kickstart the plot.
Batman Gambit: The entire vampire story is made up by him, in order to keep the Herzen fortune safe. Anyone who comes too close to the mines or castle is kidnapped and tied up, and then let free once properly scared.
Blond Guys Are Evil: It looks this way, but in reality he was paranoid due to the fact that he's been stuck in a completely empty city for the past 50 years, believing that his fiancee left him for another lover, and much much more.
Dub Name Change: Anton in the North American version, Vladimir in the European version, and Anthony in the Japanese version.
Dub-Induced Plot Hole: His bonus puzzle cameo in the NA version of Unwound Future uses his Japanese name of Anthony, not Anton.
The Reveal: Is he really a vampire? Turns out he wasn't one in the end. Due to him believing he never aged due to the hallucinogenic gas escaping from the tunnels under his castle, and the fact everyone who enters the town takes it in, it spread rumors about him being as such.
Happily Adopted: During the Summation Gathering, Layton outlines Clive's biography, noting that after the deaths of his parents he was adopted by a wealthy old woman, Constance Dove, who doted on him and was much loved by him in return until her death five years later. The fortune she bequeathed to him is how he financed the whole operation.
I Cannot Self-Terminate: Clive tells Layton that deep down, he was hoping that the professor might be able to talk him out of his insane plan, as he was too consumed with hate to stop himself.
Well-Intentioned Extremist: Clive denies what he's doing is for revenge, insisting that it's really for justice against single-minded scientists and corrupt politicians. However, after seeing how the incident that killed his parents was swept under the rug despite the severity of it, Clive believes that only a massive act of destruction could possibly change anything; cue enough military hardware to turn London into a crater.
Layton's college sweetheart who died in an accident with a Time Machine.
But Now I Must Go: At the end of the game, goes back to her own time and her own death, in order to avoid disrupting the flow of time.
Dude Magnet: Caught the attention of three men - Layton, Don Paolo, and Dimitri. The plot partially revolves around this fact!
I Want My Beloved to Be Fashionable: When Layton got the job of professor, Claire bought him a top hat as a present, saying that as a member of the academic community, he needed to look the part as a gentleman.
Oblivious to Love: Possibly in the case of Don Paolo. She was in a relationship with Layton, and it's stated she was aware of Dimitri's feelings for her even though she didn't return them; however, it's never made clear if she even knew who Don Paolo was, let alone that he was in love with her.
Undeath Always Ends: Zig-zagged. First everyone thought she was dead. The truth is that she was sent into the future, 10 years after her death, but that doesn't last, as she has to go back to the time when she died.
Claire's sister who aids the heroes in Unwound Future.
Big Damn Heroes: She pulls the Layton team out from a tight spot while in Dimitri's research facility.
Never Got to Say Goodbye: She explains that she and Claire had been estranged when the accident occurred, and that her biggest regret is how she didn't try to make amends with her sister before it was too late. This is presumably so that Layton won't question why Claire never mentioned her.
Save the Villain: Saves Clive, largely out of feeling responsible for the tragedy that cost him his parents.
Time Traveler: Celeste is really a time displaced Claire, but the effect is temporary, and she knows she will be sent back to the experiment where she was/will be killed.
Uncanny Family Resemblance: Everyone who knew Claire is taken aback by how much her sister looks like her. Of course, that's because they're really the same person.
Thou Shalt Not Kill: Layton realizes that he's bluffing when he claims that the room they're in is rigged with explosives, noting that while he has used many immoral tactics in the pursuit of the plan, he would never actually kill anyone.
Karma Houdini: Causes the incident that kills Claire, Clive's parents, and several others out of greed; uses the money to climb the political ladder and become Prime Minister; uses his influence to cover up the details of the initial incident which indirectly leads to Layton getting assaulted while investigating; and in the end all he gets is an indirect remark from Chelmey. No doubt there are many players that wish they could have stuffed him back in that reactor. However, Chelmey, the most respected police officer in London (who is also keen on justice) knows about the secret, and doesn't seem afraid to bring it up. At minimum, Bill won't be re-elected.
Big Brother Instinct: Even though he's the younger sibling he won't stand for anyone talking smack about his sister and even takes it upon himself to feed them after their servants were let go following their father's death.
Master of Disguise: Perhaps not on the same scale as Don Paolo or Descole, but he's good enough to fool most people. He dresses up as Seamus, an elderly gardener.
Sweet Tooth: How Layton was able to deduce the identity of Black Raven; it's proof that the members who comprise him are children, since only they can buy the candy he saw.
Characters in Miracle Mask
"Every puzzle has an answer."
An optimistic, adventurer rich kid who befriended Layton during his teen years and is the one who got Layton into archaeology. He's also the childhood friend of Angela and Henry. In Miracle Mask, it is shown that he fell into a hole when teen!Layton went with him into a temple to investigate the Mask of Chaos.
Adventurer Archaeologist: Well, he was aspiring to be one. However, In the Miracle Mask credits, it seems like he's into archaeology again.
We Used to Be Friends: Partially with Layton, and more so to Angela, but most of all to Henry, whom he feels betrayed him. The feeling is not mutual.
Hello again, Hershel
Randall and Layton's old friend (though her relationship with the last one is not clear). She is described as a beautiful young girl, enthusiastic and sophisticated. In the present, she is Henry's wife.
Arranged Marriage: Was meant to marry the richest guy in Stansbury by her parents. Randall was the one whom she truly loved, but when he disappeared, Dalston was the second option. She ends up marrying Henry who became the richest person. Though it was a convenience marriage just so that her parents would stop bothering her, and she never stopped believing that Randall was still alive somewhere.
Girl in the Tower: The Gentleman steals her away at one point in the game, and the others have to rescue her.
Memento MacGuffin: Her pearl necklace turns out to be this... or, rather, the pendant she has attached to it on the reverse side to what she wears. It's a charm Randall gave to her to promise her he would be careful when he embarked on his archaeological quest with Layton. He never came back, and Angela kept it with her as a reminder of him always.
Undying Loyalty: To Randall (although he doesn't realize it until it's almost too late).
One of Randall's servants and his childhood friend. After Randall's disappearance he got rich and now he is one of the most influential people of Monte d'Or, a popular Las-Vegas-like casino city, with Angela as his wife.
Ambiguously Gay: An effeminate design for one. And there's the reveal that Henry remembers his friend very fondly indeed and only married Angela so that they could BOTH wait for Randall's return...
Blond Guys Are Evil: Subverted. He looks like a rich and evil blonde, but he's really a nice person.
Rich People: In order to marry Angela he had to be rich.
Orphan's Plot Trinket: He is an orphan, and the robot given to him by Randall certainly counts as this. It is a memento of the day when he first became friends with Randall; a friendship which Henry has cherished for his entire life, as he felt Randall was one of the only people who treated him like a person and not a nuisance.
Undying Loyalty: Randall (although he doesn't realise it until it's almost too late).
Used to Be a Sweet Kid: Not as extreme as some of the more spoileriffic examples, but he has changed a great deal from the polite and subservient boy he used to be, and initially seems cold to Hershel.
The Masked Gentleman
Welcome, Ladies and Gentlemen...
The antagonist of Professor Layton and the Miracle Mask, this mysterious masked gentleman has been terrorizing the city of Monte d'Or and is the reason why Layton and Luke are called to the city. He appears to posses magical powers bestowed to him by his mask, which he apparently plans to use to destroy Monte d'Or.
Room Full of Crazy: Effectively manages to turn the Reunion Inn into this, in particular leading the main team through a treasure hunt to collect all the installments of a story detailing his jealous sense of betrayal, which ends in an actual film.
I Never Said It Was Poison: He incriminates himself by revealing something he shouldn't have known about the fake artifacts that were returned, indicating that he was the one that returned them as fakes.
Smug Snake: He's fairly arrogant, if a bit more competent than most of the people working on the case besides Layton, and DCI Carmichael dislikes his attitude.
The Mole: He's one of Targent's most important moles, giving them intel on Scotland Yard. This is made apparent in Miracle Mask, but Layton doesn't get to expose him until Azran Legacy.
Characters in Azran Legacy
A mysterious girl found sealed within a giant block of ice beneath the town of Froenburg. Though largely amnesiac, she claims to be the final survivor of the Azran, and joins Layton on a trip around the world to recover her memories and uncover the Azran's legacy.
Because You Were Nice to Me: Layton, Luke, Emmy and Sycamore treat Aurora kindly throughout their adventures to find the Eggs. This kindness is repaid when Layton, Emmy, Descole, Luke and Bronev sacrifice their lives to deactivate the Azran Sanctuary. Aurora convinces the Azran Light that humans aren't all bad and that they could work together for a brighter future, allowing Layton and co. to be brought back to life.
MacGuffin Girl/Apocalypse Maiden: Targent and Professor Layton's group spend a few hours of Azran Legacy chasing after her. Given that she's the last of the Azran and the key to finding the eponymous Azran Legacy, it makes sense that everyone is trying to find her. The fact that she's actually a golem required to activate the Azran Sanctuary and the killer golems within isn't revealed until the climax.
The Makeover: Emmy helps her buy more casual clothes in London to help her get around easier.
Pink Is Feminine: Her Azran robes are mostly pink and she has a bracelet with a pink gemstone.
She also gets a pink sweater later as part of her disguise.
A well-known archaeologist who calls upon Layton to investigate Aurora's case. Once she's revived, he provides Layton with access to his personal airship for use to travel around the world and joins them on their journey.
Doting Parent: Occasionally has shades of this towards Aurora, even becoming...
Team Dad: ... alongside Layton, dispensing helpful advice to Aurora and Luke — and even teaming up with Layton to warn a young lad in Froenborg against foolishly trying to jump onto some ice.
Living a Double Life: Desmond Sycamore is actually an alter ego and the more public identity of Jean Descole. It is also implied that he lived under this alias for some time in his attempts to have a normal life with hope and not revenge.
Bad Boss: More than willing to sacrifice his own men if it means reaching his goal. In fact, it's precisely what he did as he went through the Azran Sanctuary, to the point that he, Emmy, Robin, and Macaw are among the very few surviving members by the end of Azran Legacy.
Big Bad: of Azran Legacy, and a bit of Arc Welding makes him this for the entire prequel trilogy.
Chekhov's Gunman: He makes a pair of appearances late in Miracle Mask, but doesn't directly interact with Layton until Azran Legacy.
Love Makes You Evil: He's obsessed with the Azran Legacies because he and his wife truly believed they could be used to help the world, and her dying wish was that he find them no matter what.
Redemption Equals Death: Sort of. He sacrifices himself in Aurora's stead to stop the Azran doomsday device, and is brought back to life along with Descole and Layton's crew by Aurora's final plea to the Azran.
Well-Intentioned Extremist: Despite going from captured archaeologist to the leader of Targent, and fully embracing ruthlessness along the way, he truly believed that the Azran Legacy was a great gift that would benefit all of mankind. When he finally realizes the truth in the end, he is devastated.
Would Hit a Girl: Even after finding out that Aurora needed to be sacrificed to activate the Azran Sanctuary, he's still willing to go through with it. He only pauses briefly before stabbing Aurora through the heart. She doesn't die from the wound, being a golem, but at the time, nobody knew that. To Layton and co., it looked like Bronev had just casually murdered a young girl.
Robin and Macaw
A pair of Targent agents who cross paths with the professor many times over the course of the game. Macaw is the more serious and competent of the two, while Robin is enthusiastic but prone to running off on wild goose chases.
A former student of Professor Layton's who now works as an opera singer. She sends the Professor a letter and some tickets, asking him to come see her perform in The Eternal Kingdom so he can help her solve a perplexing mystery.
