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. Beware of unmarked spoilers, as well as unmarked trope names that can give the plot away. You Have Been Warned!
This page only includes characters from the original series of games. For characters from spin-offs, see:
- Professor Layton vs. Phoenix Wright: Ace Attorney
- Layton Brothers: Mystery Room
- Layton's Mystery Journey: Katrielle and the Millionaires' Conspiracy
Note: This series has too many characters if you include every single NPC, so let's just stick to the main cast.
Main Characters
Professor Hershel Layton
Voiced by: Yo Oizumi (Japanese), Christopher Miller (English), Martial Le Minoux (French), Mario Hassert (German), Oliviero Corbetta (Italian)

The protagonist. A gentlemanly archaeologist famous for his puzzle-solving skills.
- Absent-Minded Professor: Downplayed. While his competence and intelligence are much more prominent, he is not without his eccentricities. His obsession with puzzles and the like often lead to him getting distracted by them, his study is full of scattered books and outdated reminders to himself, and he's notorious for skipping out on his actual job whenever a fancy strikes him.
- Action Dad: He becomes Flora's adoptive father (and then later Alfendi and Katrielle's) and he's no slouch at fencing.
- 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.
- Adventurer Archaeologist: Although he repeatedly gets mistaken for a detective in Professor Layton and the Curious Village.
- Amateur Sleuth: Constantly gets roped into solving crimes thanks to his puzzle-solving skills.
- Ambiguously Jewish: His first name, Hershel, is extremely uncommon outside the Jews. It would also explain his insistence on Never Bareheaded, but this does eventually get properly explained in Professor Layton and the Unwound Future with a different reason.
- Babies Ever After: Alfendi and Katrielle are his son and daughter (respectively), confirming that either he eventually married someone or he adopted more kids like he did with Flora. Kat eventually reveals that she is indeed adopted, while we still don't know about Alfendi.
- Badass Bookworm: In addition to being a professor and master puzzler he is also pretty good at hand to hand combat and being a badass.
- Beware the Nice Ones: There are some things that Layton simply will not tolerate. Threatening the innocent citizens of London, for example, will turn him into an Implacable Man who will not stop until he's stopped you. And don't even think about touching those kids.
- Black Bead Eyes: A rare example for a human Round Character who manages to show a lot of emotion with them. Their expression becomes quite unsettling when he finally gets angry (see Tranquil Fury, below).
- Bluff the Impostor: He prefers this method when accusing someone.
- Broken Ace: Happens three times in the series: when Luke is captured by Targent, when his parents are threatened by its leader, and when he finds out Jean Descole's secret.
- Cain and Abel: The Abel to Descole's Cain, though he and the audience don't learn this until the sixth game.
- Catchphrase: "This reminds me of a puzzle..."
- "Every puzzle has an answer."
- "Critical thinking is the key to success!"
- Cool Car: The Laytonmobile; in Professor Layton and the Curious Village he freely admits that "I adore the contraption." Its coolness gets cranked up thanks to Don Paolo's modifications in Professor Layton and the 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 Professor Layton and the Last Specter it's clarified that at the age of 27, he became the youngest professor ever to join the Gressenheller staff.
- Cultured Badass: Loves his tea, loves his puzzles, loves being a gentleman. Then you hand him a sword and you quickly come to realize he's arguably the best fighter in the series as a whole. He just prefers not to, because a gentleman doesn't perpetuate violence, you see.
- Declarative Finger: He likes using this pose when making a point or explaining something.
- Disappeared Dad: He's currently missing as of Layton's Mystery Journey: Katrielle and the Millionaires' Conspiracy, having disappeared sometime during Katrielle's childhood. The end of Layton Brothers: Mystery Room indicates he's still alive, but his whereabouts are still unknown.
- In episode 35 of Layton's Mystery Journey, it's revealed that he was cryogenically frozen together with Luke.
- Doting Parent: To 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).
- Dub Name Change: From Leopard Rainel to Theodore Bronev.
- Everyone Went to School Together: Or in this case, university. It's revealed that he and Don Paolo went to the same university in the third game.
- Expy: Akihiro Hino from Level-5 revealed that he's actually a 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.
- With this, it's not too surprising Professor Layton vs. Ace Attorney happened.
- Face Palm: Covers his eyes with his hat whenever he gets a puzzle wrong.
- Famed in Story: Even though he is no detective, he's famous in and around London for his intelligence and skill in puzzle-solving. It doesn't extend to America however, as he's only an anonymous gentleman there.
- For Your Own Good: when he runs out on others to protect them.
- Gentleman Adventurer: Several games worth of adventures at that.
- Gentleman and a Scholar: Very well mannered and well read, as per job description.
- Gentleman Detective
- "Actually, I'm a Professor of Archaeology."
- Gentleman Snarker: Downplayed, but occasionally in Professor Layton and the Unwound Future.
- He also has a moment of this when accusing Doland and Jakes of being behind the attacks during Professor Layton and the Last Specter, which is mixed in with a bit of Tranquil Fury.Layton: However, even when Luke's predictions were wrong, residents were still evacuated from the the neighborhoods where the specter appeared. Isn't that odd? I find that odd. Doland, do you find that odd?
- He also has a moment of this when accusing Doland and Jakes of being behind the attacks during Professor Layton and the Last Specter, which is mixed in with a bit of Tranquil Fury.
- 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 he is not exactly out of shape.
- Giving Someone the Pointer Finger: He loves doing this while accusing people or when he gets a puzzle correct.
- Happily Adopted: Like his own children (Flora, Katrielle, and presumably Alfendi), Layton was adopted as a young child. He had no memories of his biological parents and older brother, due to the traumatic circumstances he endured for much of his life, until the end of Professor Layton and the Azran Legacy.
- Leitmotif: His theme.
- Like Father, Like Son: Although as revealed in the Professor Layton and the Miracle Mask why he became an archaeologist back then, it was hardly a coincidence that in the next game he took after his biological father, Leon Bronev, who also became an archaeologist after discovering an ancient artifact as a child, and his older brother, Descole, followed for revenge against Targent. It's also a case of Like Father, Unlike Son because Bronev is despicable and selfish rather than a loving father. Eventually, Targent abducted him and his wife, Rachael, leaving Layton (known by his real name, Theodore) and Descole (Hershel) as orphans.
- Never Bareheaded: Never removes his hat. Though he does actually take it off briefly in the ending cutscene of Professor Layton and the Lost Future. Even in flashbacks before getting his famous top hat, he wears a cap. Averted in the Flashback sequences of Professor Layton and the Miracle Mask, where his younger self has a massive and unruly mop of hair. Which might be why he wears a hat all the time.
- Nice Guy: Hershel is polite, gentlemanly, and willing to help people in need.
- O.O.C. Is Serious Business: He never leaves a puzzle unsolved, and for good reason as most of the games have points where you need a certain amount of puzzles to advance.
- You know something is wrong when he loses his unflappable composure, as evidenced when Claire reveals she's going back in time to the moment where she was killed.
- Out-of-Character Moment: He breaks his gentleman code several times throughout the events of Professor Layton and the 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: Professor Layton and the 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.
- Parental Abandonment: When he was a child, Targent kidnapped his birth parents, Leon and Rachael Bronev, leaving both him and his brother behind.
- Parental Substitute: Acts this way to both Flora and Luke; in Luke's case it seems to be a matter of in loco parentis, as Luke's parents are both alive and well and have presumably given their permission for him to travel with their old friend Layton. Flora, on the other hand, is legally his ward.
- Please, Don't Leave Me: At the end of Professor Layton and the Unwound Future Layton, so upset that Claire has to leave him so she can die, practically demands that she stay.Layton: You can't go! I don't want to say goodbye again! I can't! I WON'T!
- A flashback in Azran Legacies shows he had this attitude towards his brother too.
- The Professor: Literally, as this is his title.
- Promotion to Parent: When he becomes Flora's guardian.
- Quintessential British Gentleman: Don't get between Layton and his tea.
- Real Men Hate Affection: Weirdly downplayed. While Layton doesn't verbally mention that he doesn't like physical affection, he usually seems caught off guard when someone hugs him and returns the gesture by putting his hands on their shoulders.
- This is averted with the Layton Mystery Journey anime, where he gives Katrielle a full hug after finally reuniting with her.
- Signature Headgear: Wears a tall top hat, and is the only character to do so. This becomes a plot point in Professor Layton and the Unwound Future, where several characters in Future London recognize the Professor by his hat alone, with one even hiding in fear from him.
- Sink or Swim Fatherhood: With Flora. He may not understand how much he hurts her when he leaves her behind, but he tries his best and he clearly loves her.
- Spell My Name with an S: Hershel Layton, not Herschel Leighton.
- Stepford Smiler: While his politeness is genuine and his obsession with puzzles is never a hindrance, Professor Layton and the Unwound Future reveals that they're byproducts of his love life with Claire gone horribly wrong, and as such are coping mechanisms for his trauma.
- Stiff Upper Lip: For all the weirdness and dangerous situations that get thrown his way, Layton never loses his composure. The ending of Professor Layton and the Unwound Future is one of the few times Layton's Stiff Upper Lip falters.
- Strong Family Resemblance: Averted. Despite being his parents, Roland and Lucille don't resemble him much. That's because they're his adoptive parents. As soon as you see what his biological parents, Leon and Rachel Bronev, look like, the resemblance to his mother can't be mistaken.
- Tall, Dark, and Handsome: Has a lean figure, tan skin and dark attire, and has a pleasant face at all times. He is specifically described as such in Professor Layton and the Diabolical Box.
- Tranquil Fury: Seen only in Professor Layton and the 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.
- Unfazed Everyman: While Layton has his quirks, when placed up against the Crapsaccharine Cloudcuckooland that is the franchise's interpretation of London, he serves to be the most down-to-earth and identifiable one of the bunch.
- Unknown Rival: Has one in Don Paolo. It's revealed in Professor Layton and the 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.
- White Sheep: Averted. He didn't know his real family had become evil; he was just lucky enough to have loving, adoptive parents. Discounting this, he's pretty much the only living person in his bloodline who does not resort to criminal acts to get his way or become a full-blooded sociopath, like his father, brother, and son.
- You're Not My Mother: "You're Not My Mother and Father". At the end of Azran Legacy, he tells Leon Bronev that he considers the Laytons to be his real parents, but he remains open to the possibility of seeing Leon as a fellow archeologist.
Luke Triton
Voiced by: Maki Horikita (Japanese - Games), Soma Saito (Japanese - Layton Mystery Detective Agency), Lani Minella (English - North America), Maria Darling (English - United Kingdom and Professor Layton vs. Phoenix Wright: Ace Attorney), Marie Zidi (French), Sophia Längert (German), Cinzia Massironi (Italian)

The professor's apprentice. Aspires to be a gentleman when he's older.
- Adorably Precocious Child: Always trying his darnedest to be a true gentleman like the professor.
- 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 Professor Layton and the Diabolical Box, it's noted that Luke orders twice as much food as Layton in the train's dining car. And in Professor Layton and the Unwound Future, Flora remarks that he always seems to order half the menu whenever they dine out.
- Bratty Half-Pint: Has shades of this, as he isn't quite a gentleman yet, and makes a few openly rude remarks toward some of the more obnoxious NPCs that often result in the professor scolding him.
- Cheerful Child: He's raised in a rich household (his father being a mayor), and they have a butler and a maid so he's very comfortable. He's a really sweet boy, very friendly to new people, and loves animals and stuffed animals.
- Famed in Story: In The New World of Steam, he's built himself a good reputation as a detective in Steam Bison, by helping solve various mysteries.
- Crossdressing Voices: His voice actress is a woman. He isn't.
- Determinator: He's a plucky kid, always sticking by the professor's side since he was 10.
- Giving Someone the Pointer Finger: Yep, him too, when he solves a puzzle correctly.
- Face Palm: When he gets a puzzle wrong, he does a classic example of this.
- He Is All Grown Up: We see his adult self in Layton Mystery Detective Agency and puberty has definitely treated him well.
- The Hermit: Somewhat in Professor Layton and the Last Specter 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 (his father).
- Honorary Uncle: To Katrielle, who even calls him "Uncle Luke".
- Insistent Terminology: He is Layton's apprentice. Don't bother trying to put another word on their relationship; he even cuts off Layton himself whenever he tries to clarify the issue.
- And in Professor Layton and the Eternal Diva, he cuts off Emmy when she suggests he could be Layton's second assistant. "Apprentice, NUMBER ONE!"
- Keet: Very excitable and enthusiastic almost constantly, you almost wonder where he gets his energy from.
- Leave Me Alone!: In Professor Layton and the Last Specter, ten-year-old Luke has become withdrawn, spending most of his time in his room, as a result of the events in the game's Backstory. Layton helps him to open up more.
- Leitmotif: He finally gets one
in Professor Layton and the Eternal Diva. Given the scene it accompanies, some fans joke it's his Invincibility Theme. Seriously.
- Never Bareheaded: Always wearing a blue paperboy hat. It's stated in one of the Professor Layton and the Curious Village meta-puzzles that he never takes it off.
- Nice Guy: Putting aside his faults, he's normally kind and friendly.
- Pink Girl, Blue Boy: While Flora wears a fair bit of pink, Luke's signature colour is very much blue.
- Speaks Fluent Animal: The English version of Professor Layton and the 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 Professor Layton and the Diabolical Box and Professor Layton and the Unwound Future, and Professor Layton and the Last Specter shows that he's been able to do it for years.
- Tareme Eyes: He has round eyes.
- Time-Shifted Actor: He is voiced by Maki Horikita, Lani Minella, and Maria Darling as a child, by Shun Oguri and Yuri Lowenthal as Future Luke in Professor Layton and the Unwound Future, by Soma Saito as an adult in Layton Mystery Detective Agency, and Mio Imada as an early teen in The New World of Steam. Subverted with Future Luke since he's only Clive pretending to be one.
- Took a Level in Badass: By The New World of Steam, he became more confident and independent, and built himself a good reputation as "Detective Luke" in the town of Steam Bison.
- The Watson: Having this role in the games makes him something of an Ascended Fanboy, since in Professor Layton and the Unwound Future he remarks that he's read the Sherlock Holmes books many times over.
Flora Reinhold
Voiced by: Mamiko Noto (Japanese), Lani Minella (English - Games), Claire Morgan (English - Professor Layton and the Eternal Diva), Cinzia Massironi (Italian - Games), Francesca Tretto (Italian - Professor Layton and the Eternal Diva)

A mysterious girl from St. Mystere, who turns out to be not only the daughter of Baron Reinhold, but the Golden Apple the baron mentioned in his will.
- Blue 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.
- 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 Professor Layton and the 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 Professor Layton and the Unwound Future, but it's also very clear that they care about each other quite a bit.
- Daddy's Girl: Curious Village makes it clear that her father, Baron Reinhold, absolutely doted on her.
- Demoted to Extra: From being the Living MacGuffin of the first game to spending most of the second game sleeping in a barn to being little more than The Load and a Damsel in Distress again in the third game.
- Designated Victim: Whenever someone needs to be put in danger or kidnapped, it's usually her.
- Distinguishing Mark: She has a birthmark on her collarbone which is significant to the secrets of St. Mystere.
- Dub Name Change: From Aroma Rhineford, in Japanese.
- Fish out of Water: In Professor Layton and the Diabolical Box, she admits to being this, and is enraptured by new experiences such as a simple country fair.
- Flat Character: Besides being the Golden Apple, Flora doesn't do anything except remark on Layton's actions, tease Luke, and cook bad food. Whenever it's time for them to go on an adventure and she wants to take part in it, she's either left behind, must be rescued, or simply doesn't contribute, thus you never get any real chance to know her besides, again, the fact she's the Golden Apple.
- Give Him a Normal Life: The Professor keeps her origin story a secret so that she and her village are not subjected to a media circus. This may also be a reason for him not bringing her along on cases - to keep her safe and able to live a normal life.
- Giving Someone the Pointer Finger: She doesn't get to solve any puzzles until Professor Layton and the Unwound Future, but sure enough, when she gets it right...
- Good Eyes, Evil Eyes: She has easily the largest eyes of anyone in the cast, ostensibly to further illustrate how sweet and innocent she is.
- Happily Adopted: She seems to like being Layton's foster daughter. 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 Professor Layton and the Curious Village, she's pretty happy to be with the Layton crew.
- Hates Being Alone: She has an immense dislike feeling of being alone and being left behind - which is what usually happens.
- The Ingenue: A very innocent (and adorable) young lady, to the point where Luke can seem more worldly and mature than she is despite being younger.
- Lethal Chef: The credits of Professor Layton and the Curious Village make it pretty clear that Flora has never cooked before in her life. By the end of Professor Layton and the Unwound Future though, she's graduated to Cordon Bleugh Chef.
- Living MacGuffin: Only in the first game. She is the Golden Apple.
- The Load: She's insistent on joining Layton and Luke on their adventures despite the fact she never does anything to contribute to them.
- Locked Up and Left Behind: In all three games in one way or another.
- Lonely Rich Kid: The first game only, since after that she has Luke and the Professor to keep her company.
- Mysterious Waif: In Professor Layton and the Curious Village.
- Naďve Newcomer: Flora is a bit awkward around new people and tends to explain her thoughts aloud.
- Neutral Female: She stows away wherever the Professor's going, and basically does nothing else. While she takes on a handful of puzzles in Professor Layton and the Unwound Future, she only takes on one plot-important puzzle (the one at the factory entrance) out of dozens.
- Nice Girl: Flora is generally very sweet.
- Paper-Thin Disguise: Her... 'disguise' in Professor Layton and the Curious Village, which she later uses in Professor Layton and the Diabolical Box as well. This also overlaps with Iconic Outfit.
- Pink Girl, Blue Boy: The Pink Girl to Luke's Blue Boy.
- Pink Means Feminine: She often wears pink and other warm pastel colours.
- The Pollyanna: Despite her past, she is a very determined and positive young lady.
- Pretty in Mink: In Professor Layton and the Diabolical Box, she wears a short cape trimmed with white fur
◊.
- Promoted to Playable: By Professor Layton and the Unwound Future, she can do puzzles herself just like Layton and Luke.
- Tareme Eyes: She has round eyes, befitting for The Ingenue.
- The Un-Favourite: 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 autophobia
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 Professor Layton and the Diabolical Box Luke 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 they were stuck in that town.
- In Professor Layton and the Unwound Future she's upset at being left out again and makes Layton promise to bring her along. Rather than keep the promise, or at least explain 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 doing. (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 Professor Layton and the Last Specter, and thus twelve or thirteen by the time of Professor Layton and the 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.
- When You Coming Home, Dad?: Flora often feels this way about the Professor and his adventures.
- Why Did It Have to Be Snakes?: She seems to have an intense fear of being left alone. It gets the
Woobie treatment in Professor Layton and the Diabolical Box, but Professor Layton and the 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.)
Dr. Andrew Schrader
Voiced by: Rokurō Naya (Japanese), Stuart Organ (English - Professor Layton and the Eternal Diva)

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.
- Distressed Dude: His in-game profiles state he's a tendency to get into trouble, forcing his students to bail him out. Apparently, the Elysian Box fiasco is just one of many times this has happened.
- Dub Name Change: A subtle one; his surname's spelled "Schröder" on supplemental materials featuring him.
- Dying Clue: The letter he sends to Layton, kickstarting the plot of Diabolical Box.
- Spell My Name with an S: His surname; it's spelled "Schrader" in the English scripts, but spelled "Schröder" on certain things featuring him.
Emmeline "Emmy" Altava
Voiced by: Saki Aibu (Japanese), Lani Minella (English - Games), Emma Tate (English - Professor Layton and the Eternal Diva)

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 favour somehow. Her wish is fulfilled some years later when, in Professor Layton and 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.
- Action Girl: She is the most competent physical fighter of the second trilogy, able to chase after the Black Raven jumping from rooftop to rooftop. Because the series is a puzzle game, her fighting skills are most likely to be shown in cutscenes only.
- The Apprentice: Though not to the same extent as Luke, Emmy does take lessons from the professor in observation and puzzle-solving.
- Ascended Fangirl: 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.
- Because You Were Nice to Me: She decides to get a job as Layton's assistant sometime after he clears her name on a pickpocket case. However, at the end of Professor Layton and the Azran Legacy, she's revealed to have been working for Targent all along to get close to him. She did so to help Layton convince Bronev to end his obsession with the Azran civilization for good, and her friendships with Layton and Luke are genuine.
- 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.
- Cool Big Sis: To Luke, and to Aurora in Professor Layton and the Azran Legacy.
- Deadpan Snarker: Very prone to snarking.
- Declarative Finger: Is fond of doing some form of this. (Exhibit A: the picture above)
- Dub Name Change: From Remi Altava.
- Drives Like Crazy: And Luke has no trouble calling her out for it.
- Eaglelander: Invoked. One character in Professor Layton and 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 Professor Layton and the 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.
- Kick Chick: She does kicks in any fight shown in cutscenes.
- Leeroy Jenkins: Of a sort; her first answer to almost every hurdle is a good roundhouse kick.
- The Mole: She's actually a spy for Targent, and describes Bronev as being like family to her after all he's done for her.
- Supreme Chef: A scene in the credits of Professor Layton and the Last Specter shows her cooking a meal for Rosa and Layton, both enjoying the meal.
- The Team Wannabe: To Team Layton. More Sidekick than Team, though.
- 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.
- Walking Spoiler: Azran Legacy reveals a twist about why she pursued to be Layton's assistant.
Inspector Chelmey
Voiced by: Shiro Saito (Japanese), Christopher Miller (English - Games), Jonathan Keeble (English - Professor Layton and the Eternal Diva)

An infamous (among criminals, that is), grumpy detective from Scotland Yard. He doesn't always live up to his reputation, though.
- Bad Boss: It's implied by Constable Barton that he treats the other constables badly if one of them messes up an investigation.
- The Cameo: In Professor Layton and the Last Specter, he and Barton appear briefly, and only Emmy encounters them.
- He makes another quick appearance in Professor Layton and the Azran Legacy having 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: Professor Layton and the Last Specter reveals that when he was a constable years ago, he was assigned a case that would promote him to Inspector. In his rush to receive the promotion, he ended up forcing the then current Inspector to take the bullet for him. After this incident, he became extremely dedicated to his job but also learned to take things slow.
- Iconic Sequel Character: While he is an important character in the Professor Layton franchise, Chelmey technically doesn't appear until the second game as his appearance in the first game was actually Don Paolo in disguise.
- 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.
- Inspector Lestrade: To Layton's Sherlock.
- 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.
- Overshadowed by Awesome: He's apparently a detective of considerable renown, but when up against someone like Layton on cases as bizarre as these, he comes off as hopelessly inadequate.
- The Real Remington Steele: The Chelmey in Professor Layton and the 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 Professor Layton and the Curious Village.
- Wrong Genre Savvy: Acts like he's the hero of the mystery stories, not the Arrogant Cop Who Jumps To Wrong Conclusions.
Constable Barton
Voiced by: Hiromi Sugino (Japanese), Wayne Forester (English - Professor Layton and the Eternal Diva)

Chelmey's Sidekick from the second game onwards. Not much is learned about him until Professor Layton and the Unwound Future.
- Artistic Age: He looks like he's in his thirties or so, but he's really only 27.
- Big Eater: Hence his weight.
- The Cameo: In Professor Layton and the Last Specter, he and Chelmey appear briefly, and only Emmy encounters them.
- Future Badass: Went from Chelmey's sidekick to Commissioner of Scotland Yard in Layton Brothers: Mystery Room.
- Police Are Useless: It's essentially stated that the only reason he still has a job is that Chelmey won't let him be fired for his many mistakes.
- Remake Cameo: Appears again as Commissioner Barton in Layton Brothers: Mystery Room.
- Sidekick: To Chelmey.
Inspector Clamp Grosky
Voiced by: Hōchū Ōtsuka (Japanese), Walter Rego (English - Games), Stuart Organ (English - Professor Layton and the Eternal Diva)

An inspector from Scotland Yard who takes pride in his work and is very athletic.
- Anime Hair: A giant pompadour.
- Carpet of Virility: Shaped like a heart no less.
- Dodge the Bullet: In Professor Layton and the Azran Legacy from hitmen sent by Targent.
- 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.
- Impossibly-Low Neckline: Inexpicable male example, just look at him! With a fully buttoned button-up-shirt no less!
- Iron Butt Monkey: A lot of unfortunate things happen to him as per Rule of Funny, but he can take it.
- Passing the Torch: He gives Chelmey the inspector position after the prequel trilogy
- Top-Heavy Guy: Essentially his upper body is an upside-down triangle with a furry heart on it.
Don Paolo
Voiced by: Minoru Inaba (Japanese), Christopher Miller (English - Games), Jonathan Keeble (English - Professor Layton and the Eternal Diva)

- Anime Hair: Devilish Hair Horns, to be precise.
- Anti-Hero: He becomes this in Professor Layton and the Unwound Future.
- Big Bad: Of Professor Layton and the Curious Village. He's arguably this to the entire first trilogy, as well, being Layton's most recurring foe.
- The Cameo: At the beginning of Professor Layton and the Eternal Diva, along with several other characters from the first trilogy.
- Creepy Crossdresser:
- In Professor Layton and the Diabolical Box, he disguises himself as Flora.
- In Professor Layton and the Eternal Diva, he dresses briefly as an elderly woman half his size.
- Dastardly Whiplash: His appearance and mannerisms make him this down to a "T".
- Do Not Call Me "Paul": Literally. His real name (in the English version) is Paul, and he hates to be called that.
- Dub Name Change: From Don Paul.
- Handwaved in the English version of Professor Layton and the Unwound Future where his real name is Paul.
- Enemy Mine: Joins forces with Layton in Unwound Future, despite his loathing of the man, because he wants to know the truth about what happened to Claire.
- Even Evil Has Standards: Remarks upon seeing a missile in Professor Layton and the Unwound Future, "Even I'd never use something like this."
- Everyone Went to School Together: Or in this case, university. It's revealed that he and Hershel went to the same university in the third game.
- Evil Genius: A Gadgeteer Genius to be more precise.
- Evil Laugh: As per Dastardly Whiplash tradition.
- Expository Hairstyle Change: In a flashback in Professor Layton and the 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.
- Full-Body Disguise: For all disguises.
- 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, which he is ostensibly in town to beat Layton to find. 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.
- Gonk: To contrast directly with Layton. As baby-faced as Layton is, he's still quite charming and easy on the eyes. Don Paolo's much more of an eyesore, what with his massive nose, devil horn-like hair, and perpetually wild look in his eyes.
- Heel–Face Turn: In Professor Layton and the 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.
- Hidden Heart of Gold/I Was Just Passing Through: He claims that he only fixed Layton's car in Professor Layton and the Unwound Future so Layton could safely rescue the kidnapped Flora.
- High Collar of Doom
- Imposter Forgot One Detail: Ultimately, this is Don Paolo's Fatal Flaw, as despite his legitimately impressive attempts to portray another person, he always forgets one small detail that blows his cover. In Curious Village, he refuses to eat anything with sugar as Inspector Chelmey, despite the real deal enjoying sweet potato fritters his wife makes. He also doesn't know Chelmey's wife's name, which is ultimately what proves he's not the real deal.
- Jerk with a Heart of Gold: He can come across as a Jerkass at first, but he helps Layton save Flora in Professor Layton and the Unwound Future.
- Kill and Replace: He's a non-lethal example. As out-of-control as he is, he never kills those he impersonates. He either kidnaps them and hides them away somewhere, or just makes sure they're not around:
- In Diabolical Box. While Hershel, Luke, and Flora are exploring Dropstone, Don Paolo manages to kidnap and pass himself off as Flora, with nobody none the wiser until they enter Folsense.
- Invoked by Layton himself in Unwound Future. Before they enter Future Layton's lair, the Professor runs off and infiltrates the place on his lonesome, while having Don Paolo take his place as they wander around. Not only does this prevent Dimitri Allen from reading Layton's mind with the glasses he puts on (since Don Paolo knows nothing about the time experiment), but it also allows the real Layton to rescue everyone when Allen traps them.
- Large Ham: Very Hammy in his appearances, especially his entrances.
- Latex Perfection: In Professor Layton and the Curious Village, he disguises himself as Inspector Chelmey with a mask featuring a full body suit. It gets more ridiculous in Professor Layton and the Diabolical Box where he disguises himself as Flora, who is about half his size. In Professor Layton and the Unwound Future, he impersonates Dr. Schrader, the Dean of Layton's university, and Layton himself during their temporary truce. Paolo pulls each one off so well that even Layton requires some serious contemplation on each person's mannerisms to begin catching on. In Professor Layton and the Eternal Diva, he disguises himself as an old lady in the intro, with a totally different body shape.
- Leitmotif: The Great Don Paolo.
- Love Makes You Evil: He hates Layton because Layton got together with the girl he loved. And Layton was oblivious to all of this.
- Mad Scientist: Of the mechanical variety.
- Master of Disguise: He crosses this with Latex Perfection. Thus far in the series, he's flawlessly impersonates everyone from Inspector Chelmey of Scotland Yard in Professor Layton and the Curious Village to Flora in Professor Layton and the Diabolical Box to Dr. Schrader and Professor Layton himself in Professor Layton and the Unwound Future!
- Master Actor: He plays his parts pretty flawlessly, and only gets revealed by minor OOC slip-ups.
- Pet the Dog: During the events of the third game, Don Paolo has repeated moments with Flora which imply that he actually has a soft spot for her. It's possible that he feels guilty for almost killing her in the first game and kidnapping her in the second, and is trying to make amends.
- As the group begins to decide who to split into groups, Don Paolo complains that Layton always gets to be the gentleman, and says that he wants to escort Flora.
- At one point when searching for the missing scientists, Don Paolo makes a remark (when you click around for quotes from the characters) that "I'll make sure Flora's safe, no matter what happens here."
- When the Professor is getting ready to rescue her after Clive kidnaps her and takes her to his fortress/weapon of mass destruction, Don Paolo tells him he has upgraded the Laytonmobile allowing it to fly. When Layton thanks him, he grumpily claims that he is only doing it for Flora.
- And in the Japanese version, he affectionately refers to her as "Aroma-chan".
- Prehensile Hair: As seen in a flashback, his hair literally took on a life of its own out of anger and heartbreak.
- Real Men Hate Sugar: Backfires on him; the real Chelmey loves his wife's sweet potato fritters.
- This Is My Name on Foreign: Wonder what Don Paolo's real name is? Don Paul.
- Token Evil Teammate: For a bit in Professor Layton and the Unwound Future, where he's in an Enemy Mine situation with Layton. He even tags along in gameplay, though he doesn't solve any puzzles.
- Unknown Rival: To Layton.
- Villain Decay: He was a genuine threat in Professor Layton and the Curious Village, where he nearly killed the Professor and Luke with a ferris wheel. However, in Professor Layton and the Diabolical Box, his evil plot takes a backseat to Anton's story and is thwarted in a rather more humorous manner than last time. Unwound Future ultimately has him working with the heroes instead of against them, and he doesn't appear in any of the other games.
Jean Descole
Voiced by: Atsuro Watabe (Japanese), Walter Rego (English - Games), Jonathan Keeble (English - Professor Layton and the Eternal Diva)

The antagonist in the second trilogy, as well as in Professor Layton and the 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 Professor Layton and the Azran Legacy as Professor Sycamore, who's affable and sociable.
- All-Encompassing Mantle: His cape covers up everything but doesn't hinder his movements at all.
- Ambiguously Jewish: He was born Hershel, an extremely uncommon name outside the Jews.
- Battle Butler: His servant Raymond counts as one. In Miracle Mask, when Descole's about to be captured, his servant throws a smoke bomb allowing him to escape before Bronev takes off his mask.
- Big Bad: Of Professor Layton and the Last Specter. He is also The Man Behind the Man in Professor Layton and the Miracle Mask.
- Cain and Abel: The Cain to Layton's Abel.
- Catchphrase: "Sasu ga dana, Reiton" could be translated as "As expected from you, Layton." It makes sense, since he sees Layton as his match for his games.
- The Chessmaster: He is very clever and good at manipulating others.
- Coat, Hat, Mask: His costume in a nutshell complete with both a hat and matching Cool Mask.
- Contrasting Sequel Antagonist: Or rather, Contrasting Prequel Antagonist - both Don Paolo and Descole are Mad Scientist Masters Of Disguise with mysterious vendettas against Layton, but the two are very different in terms of competence and personality. Paolo worked alone, and could prove dangerous at times thanks to his knack for technology, but his lack of serious planning and tendency to slip-up with his disguises meant he quickly became little more than a small thorn in Layton and Luke's sides; Descole, in contrast, has very well-laid schemes to uncover the Azran Legacies, and manipulates many people to further his goals, enabling him to hide behind the scenes while his pawns usually do the heavy lifting (Perhaps tellingly, Layton often unmasks Paolo only halfway through most of the games in the original trilogy, whereas he usually only has the opportunity to expose Descole at the very end of the games in the prequels). Don Paolo is particularly hammy and often quick to anger, while Descole is Wicked Cultured and often finds Layton's uncovering of him amusing.
- Creepy Crossdresser: Towards the end of Professor Layton and the Miracle Mask, it is revealed that he was disguised as Angela Ledore.
- Dodge the Bullet: In Professor Layton and the Miracle Mask, when Bronev and the Targent confront him.
- Domino Mask: His Cool Mask is done in this style.
- Dub Name Change: From Hershel Rainel to Hershel Bronev.
- Hair-Trigger Temper: As cool and as collected as he is, he manages to have a shorter fuse than Don Paolo.
- 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.
- Hypocrite: As we discover at the end of Professor Layton and the Azran Legacy that he's none other than Layton's biological older brother, Hershel Bronev who held a justified grudge towards Targent for kidnapping their parents for the Azran civilization, he isn't above stooping to their levels as them by kidnapping Luke's mum and butler to manipulate his dad, Clark to help him find the Golden Garden before they do, next, he manipulated Layton's high school close friend, the amnesiac Randall from the start to take revenge upon his childhood friend, Henry for 'stealing' his wealth and Angela from him to also discover the Nautilus Chamber of Akbadain before them as well and getting close to Layton as Professor Sycamore to take revenge against Targent as his next pawn.
- I Have Many Names: Jean Descole, as he is most commonly known, was born Hershel Bronev, but he gave up his name for the Laytons to adopt his brother, Theodore. During Professor Layton and the Azran Legacy, he masquerades as Desmond Sycamore.
- I Have Your Wife: Kidnaps Luke's mother and poses as his butler in order to get his father to do what he wants.
- Impersonatingan Officer: In Phantom Deity.
- Jerkass: At first, but he has had several Pet the Dog moments and hints at a Hidden Heart of Gold.
- Jerk with a Heart of Gold: He immediately comes across as selfish and short-tempered. He isn't above terrorizing entire towns to find the Azran Legacies in them, and he kidnaps and attacks many people throughout the series. However, he also goes out of his way to make sure innocents aren't killed in his schemes, such as when he corrects Luke's predictions about where the specter will appear so those areas will be evacuated beforehand and sends the losers of the game for eternal life safely back to London when he blows up the Crown Petone, even though he makes it seem like they're dead to the remaining players. In Professor Layton and the Azran Legacy, he even takes injury from a laser-shooting Azran robot pushing Luke out of its way.
- Kick the Dog:
- In Professor Layton and the Last Specter, his machines beat the poor Loosha while trying to destroy the town.
- He also ruthlessly manipulated Randall into nearly destroying Monte d'Or in order to find an Azran ruin.
- Kill and Replace: Like Don Paolo before him, he's a non-lethal example. Though Descole can get very violent, he's still humane enough to simply stow whomever he's impersonating away somewhere instead of killing them.
- Latex Perfection: He is just as ridiculous as Don Paolo. In Professor Layton and the Last Specter, he disguises as Doland Noble, an old man half his size and with a completely different body shape and in Professor Layton and the Miracle Mask, he's disguised as Angela Ledore, a woman.
- Long-Lost Relative: He's Layton's older brother.
- Mad Scientist: Mechanically based for the most part.
- Malevolent Masked Men: He and his Mooks are this.
- Manipulative Bastard: He's pretty good at this, notably with Clark Triton in Professor Layton and the Last Specter and Randall Ascot in Professor Layton and the Miracle Mask.
- Master of Disguise: He successfully impersonates Doland in Professor Layton and the Last Specter and Angela in Professor Layton and the Miracle Mask. He also masquerades as Professor Sycamore in Professor Layton and the Azran Legacy.
- Ominous Pipe Organ: His leitmotif.
- Pretty in Mink: His mantle has a fur trim.
- The Rival: He's this to Layton in the prequel trilogy, and for good reason as he's his brother.
- Two Aliases, One Character: He and Desmond Sycamore are the same person.
- Would Hurt a Child: He nearly kills Luke in Professor Layton and the Eternal Diva.
Stachenscarfen

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. He later returns in Layton's Mystery Journey: Katrielle and the Millionaires' Conspiracy, no longer teaching about hint coins but instead challenging Katrielle with puzzles (like most other NPCs).
- Berserk Button: When Layton finds out about game mechanics from someone else.
- The Bus Came Back: After being absent during the prequel trilogy, he returns in Layton's Mystery Journey: Katrielle and the Millionaires' Conspiracy; and accordingly he's noticeably older than before (in that his hair and moustache have gone white).
- Have We Met?: He always acts like it's the first time he's met you when you find him in game.
- Leaning on the Fourth Wall: Often as a part of his tutorials.
- Meaningful Name: His two distinguishing features are his 'stache and his scarf.
- Medium Awareness: Fans have theorized he may be the one person who knows that they're in a game.
- Recurring Extra: He appears in multiple games, but never as a plot-important character.
Pavel

An explorer that also shows up in every game of the original trilogy, but also has no relevance to the plot.
- Gratuitous Foreign Language: With multiple languages, including French, German, Japanese, Russian, and Spanish.
- No Sense of Direction: You always find him after he gets himself lost... except in Professor Layton and the Unwound Future, where he turns up in Future London, looking for giant underground caverns. Guess where Future London is really?
- Recurring Extra: You find him in multiple games.
Aldus
Essentially Stachenscarfen's replacement in the prequel games, filling his role as the non-plot-relevant character who helps explain game mechanics.- Anime Hair: It's a large pompadour.
- Leaning on the Fourth Wall: During tutorials.
- One-Steve Limit: In Spanish, he and Price from Professor Layton vs. Phoenix Wright: Ace Attorney have the same name: Aldo.
- Purple Prose: Tends to use flowery language.
- Recurring Extra: In the prequel games.
Granny Riddleton
An old lady who picks up puzzles people forget about. In Professor Layton and the Last Specter and Professor Layton and the Azran Legacy, her cat Keats fills in for her. She returns in Layton's Mystery Journey: Katrielle and the Millionaires' Conspiracy, but with no more need to store lost puzzles, she's revised into just being a generic "old lady" NPC.- Demoted to Extra: She started off as a mysterious secondary character in Professor Layton and the Curious Village and Professor Layton and the Diabolical Box, but was replaced by a talking bee, and later by her granddaughter in Professor Layton and the Unwound Future, where the old woman did get a small appearance near the beginning. In Professor Layton and the Last Specter, however, she simply appears as a cameo before being replaced by a cat. She does come back in full force for Professor Layton and the Miracle Mask, under the guise of Elizabeth, only to once again be replaced by the cat in Professor Layton and the Azran Legacy, making only a brief cameo to introduce the cat.
- Doomed by Canon: Canonically, Layton and Luke first meet her in Professor Layton and the Curious Village, which throws a wrench into her appearing in the second trilogy. Subverted since she manages to show up anyway: Professor Layton and the Last Specter and Professor Layton and the 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 Professor Layton and the Miracle Mask, she wears a Paper-Thin Disguise and calls herself "Nanny Grams" ("Elizabeth" in the British version).
- Granny Classic: In Layton's Mystery Journey: Katrielle and the Millionaires' Conspiracy. It seems the 20-odd years since Hershel's time have really mellowed her out.
- Have We Met?: When she meets Layton and Luke in Professor Layton and the Diabolical Box and Professor Layton and the Unwound Future, she acts as though she's never seen them before, even though they recognize her right away.
- I Was Quite a Looker: Subverted; she thinks she still is.
Characters in Professor Layton and the Curious Village
Lady Dahlia Reinhold
Voiced by: Atsuko Tanaka (Japanese)
A rich woman in St. Mystere, the widow of the recently deceased Baron Reinhold. She asks Layton to help her solve the mystery of the Golden Apple.- Artificial Human: Turns out she is one, along with everyone else in the village.
- Dub Name Change: From Salome Reinford, in Japanese.
- Ice Queen: She's very much the aloof Blue Blood in her dealings with very nearly everybody, including (occasionally) Layton.
- Identical Stranger: To the baron's beloved late wife Violet. She's actually a robot double based on her.
Claudia the Cat
Lady Dahlia's beloved pet.- Cats Are Mean: When Luke first attempts to capture the runaway Claudia, he gets some pretty nasty scratches for his efforts.
- Mister Muffykins: Despite the strange feminine name this cat is male.
- 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 Professor Layton and the Unwound Future is female.
Baron Augustus Reinhold
The late Baron of St. Mystere, father of Flora.- Doting Parent: To Flora; under his direction, an entire amusement park was built for her sole enjoyment.
- Dub Name Change: From Allen Reinford, in Japanese.
- Impossibly Cool Wealth: To the point of using 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.
- Posthumous Character: His death is the start of the entire plot.
- Royal Blood: How he got so rich in the first place.
- 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.
Matthew
The butler of the Reinhold mansion.- The Butler Did It: Averted. Matthew is probably the single most helpful resident of the entire village as far as Layton's investigation goes.
- Artificial Human: Averted to some extent, it is unknown if he too is a robot like the rest of the village.
Simon Reinhold
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.- Disney Death: It looked like he was murdered but he actually was just malfunctioning, which was an easy fix since he was an Artificial Human Like the rest of the village.
- Dub Name Change: From Roy Reinford, in Japanese.
Ramon
Known for his creepy purple lips, Ramon can almost always be found outside the mansion.- Verbal Tic: He has one of these, you know, ahoo hoo hoo!
Gordon
An old friend of the baron who is desperate to find a girl.- Sweat Drop: Taken to extremes; he's constantly perspiring and mopping his face.
Lady Violet Reinhold
The Baron's late wife and the mother of Flora.- Doting Parent: To judge by the picture of her holding baby Flora.
- Dub Name Change: From Maria in Japanese. She's also named Viola in the UK version.
- Flower Motif: She and her robot copy were both named after flowers, and Violet named her daughter Flora.
- Posthumous Character: Her death is what led to the baron's relationship with Dahlia.
Bruno
Voiced by: Motomu Kiyokawa (Japanese)
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, indicating 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 Professor Layton and the Diabolical Box
Babette
Voiced by: Salyu (Japanese)

- Entitled Bastard: Very stuck up and expects everyone to do what she says.
- Mister Muffykins: Her "little boy," Tom. He's a poodle.
- Rich Bitch: Almost like a grown up Spoiled Brat.
- Screw the Rules, I Have Money!: She usurps Layton and Luke's table in the dining car by flaunting her wealth and refusing to bow to common sense or decency.
Mr. Beluga
Voiced by: Tetsuo Goto (Japanese), Christopher Miller (English)

- Big Brother Worship: He idolized his elder brother Anton.
- Blue Blood: He is the second son of Duke Herzen and the younger brother of Anton.
- Dub Name Change: From Frederick Feruzen/Derumonen Papporacchi to Friedrich Herzen/Mr. Beluga.
- Jerk with a Heart of Gold: For all his bluster towards his employees, he shows at several points in the game to be capable of compassion. He seems mournful remembering that it had been a year since Sophia passed away, and Sam mentions that Beluga had a soft spot for his older brother, Anton, whom he left behind to escape his father's selfish ways. In the closing credits, he is shown to be very happy to see Anton again.
- Long-Lost Relative: He is the younger brother of Anton.
- The Napoleon: To some extent. He's tiny, but very hard on his employees.
Sammy Thunder
Voiced by: Ken Yasuda (Japanese)

- Dreadful Musician: Layton and Mr. Beluga think so. Luke seems to enjoy it, on the other hand.
- Dub Name Change: From Sam to Sammy.
- Nephewism: In the English version, he's Mr. Beluga's nephew. He may or may not be Anton's nephew by extension; we don't know if Sammy is Beluga's biological nephew or a nephew by marriage.
- The Power of Rock: Dreams of becoming a rock star.
Duke Anthony "Anton" Herzen
Voiced by: Takao Osawa (JP - Young), Fubito Yamano (JP - Old), Mark Carr (English), Stéphane Miquel (French), Jürgen Neumann (German), Paolo De Santis (Italian)

- Abusive Parents: Duke Herzen chose his own greed instead of the happiness of his family. His obsession actually is the starting point of the events of the game.
- Action Dad: He is a master swordsman and he happens to be a father.
- Actually Not a Vampire: He is believed to be a vampire by everybody in Folsense. However, he only played the role to scare away thieves and apathetic citizens.
- Affably Evil: He's a charming gentleman and kind enough to allow Layton a fighting chance when trying to kill the Professor.
- Agent Peacock: He's a Long-Haired Pretty Boy in a ruffle shirt. He's quite nimble for an old man, easily putting Layton into the defensive and making impressive leaps. If he had been any younger, the professor would have had a much more difficult time.
- Anti-Villain: Type II. Although he is the main antagonist, kidnaps Professor Layton and Luke, and pretends to be a vampire, he is not truly evil. He just misses the love of his life.
- Aristocrats Are Evil: He is the Duke of Folsense and the second Big Bad. Or is he?
- Badass Long Coat: He is a skilled swordsman for a seventy-year-old and has a High Collar of Doom on his black long coat with red on the inside.
- 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 set free once properly scared.
- Beauty Equals Goodness: Grinko describes his personality as beautiful as his appearance.
- Blue Blood: He succeeded his late father as the Duke of Folsense.
- Cool Old Guy: He's quite nimble for an old man, easily putting Layton into the defensive and making impressive leaps. If he had been any younger, the professor would have had a much more difficult time.
- Crazy Jealous Guy: He is paranoid that Sophia has left him for another man. He duels with Layton over his granddaughter Katia, thinking that she's Sophia and that Layton is trying to keep her from him for his own.
- Dances and Balls: Anton and Sophia, as shown in flashbacks and the painting in the room where Layton and Luke stay at Herzen Mansion.
- Disappeared Dad: He was absent throughout the entire life of his only child by Sophia. Justified in that Sophia kept him Locked Out of the Loop to protect their unborn child from the toxic, hallucinogenic gas that plagued Folsense.
- The Dreaded: He is feared by the townspeople as a vampire. It turns out to be an Invoked Trope; he's Actually Not a Vampire, but he only played the role to scare away thieves and apathetic citizens.
- Dub Name Change: Anton in the North American and UK versions, Vladimir in the French version, and Anthony in the Japanese and Spanish versions. This also causes a Dub-Induced Plot Hole in the NA version of Professor Layton and the Unwound Future, as his bonus puzzle cameo uses his Japanese name of Anthony, not Anton, although this is brushed off as his real name.
- Face of an Angel, Mind of a Demon: He is a Shojo-esque Bishōnen with long blond hair. He's also a delusional Yandere.
- Falling Chandelier of Doom: During his Villainous Breakdown, he accidentally causes his own chandelier to crash.
- Friendless Background: He comments in his diary that his status as the elder son of Duke Herzen left him with no real friends.Anton: As the duke's son, the unfortunate reality is that most people are overly polite and fawning towards me.
- A Glass of Chianti: Anton drinks red wine upon his meeting with Professor Layton and Luke. The fact that he is supposed to be a vampire does not help.
- Hair of Gold, Heart of Gold: He has blond hair and is described by Grinko as having a beautiful heart.
- High Collar of Doom: His suit has a very high collar. Considering the origin of this trope note , it fits the vampire motif.
- High-Pressure Emotion: Played with during his duel with Layton. He gets angry in the middle of it and steam eminates from him, but it's actually the gas from the mines below his castle.
- I Just Want to Be Loved: Implied. He lamented the fact in his diary that his status as the elder son of Duke Herzen made most people "overly polite and fawning towards [him]". Because of this, he fell deeply in love with Sophia, who treated him like a genuine human being, and her disappearance left him in great despair.
- Inconsistent Coloring: His eyes are turquoise outside of the cutscenes. However, in the cutscenes, his eyes appear green.
- I Was Quite a Looker: He was a Bishōnen in his younger days, yet by the time of the present, he has become a hook-nosed old man.
- Let's Fight Like Gentlemen: Anton challenges Layton to a duel, and being the good sport that he is, gives Layton a free choice of the swords on the wall.
- Light Is Not Good: He is very handsome man with blond hair and blue eyes. He's also a delusional Yandere.
- Long-Haired Pretty Boy: He has long, wavy blonde hair down to his shoulder.
- Love Makes You Crazy: He went mad because his beloved told him she was leaving him for the sake of someone she loved more than him. (She was talking about their unborn daughter.)
- Man of Wealth and Taste: He wears a high ruffled collar shirt and has a High Collar of Doom on his badass black long coat with red on the inside.
- Master Swordsman: Can hold his own against Professor Layton.
- Murder the Hypotenuse: He actively tries to kill Layton after misunderstanding the situation and thinking the Professor stole "his Sophia".
- Occult Blue Eyes: He has turquoise eyes and is a vampire. It's ultimately subverted when it turns out that he is Actually Not a Vampire.
- Older Than They Look: He only looks like a young man due to the hallucinogenic gas permeating Folsense. In truth, he's an old man.
- Outliving One's Offspring: His daughter died after Katia was born.
- Parental Incest: He mistakes Katia for his lost fiancée, Sophia, and asks her to come to him, not knowing Katia is his own granddaughter.
- 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 rumours about him being as such.
- Single Woman Seeks Good Man: Gender Inverted. He comments in his diary that his status as the elder son of Duke Herzen left him with no real friends. He eventually fell in love with Sophia because she treated him as a genuine human being.
- Surprise Incest: Narrowly averted. He mistakes Katia for his lost fiancée, Sophia, and asks her to come to him, not knowing Katia is his own granddaughter.
- Time-Shifted Actor: In the Japanese version, he is voiced by Takao Osawa as a young man and by Fubito Yamano as an old man.
- Tsurime Eyes: He has upwards arching eyes, signifying his noble upbringing and dignity.
- The Ugly Guy's Hot Daughter: Gender Inverted. He is a pale Bishōnen with blonde hair and blue eyes. His father, Duke Herzen, looked nothing like him, being a grumpy-looking old man with an aquiline nose.
- Unnamed Parent: His father is only known as Duke Herzen.
- Vampires Are Rich: He owns an impressive manor since his family owns an incredible amount of gold, to the point where there is a whole museum dedicated to the Herzens. He is also rumored to be a vampire, at least until it's revealed that he only pretends to be one as a Batman Gambit to keep his family's fortune safe.
- Villainous Breakdown: When Katia tells him that Sophia has passed away, Anton loses his cool and swings his sword around.
- Vocal Dissonance: Despite having the Bishōnen look, Anton has a deep, seductive voice courtesy of Takao Osawa. It may be a Foreshadowing towards his true age.
- Yandere: He seems to be a charming gentleman at first, but as it turns out, he waited years in the Herzen Mansion for his fiancée, Sophia, to come back. When their Identical Granddaughter, Katia, rejects his advances out of fear, he goes mad and tries to kill Layton because he misunderstands that the Professor stole "his Sophia". Justified in that the last fifty years left him lonely and in great despair, plus the hallucinogenic gas is probably enhancing his Sanity Slippage. He gets better once he reads Sophia's letter, thankfully.
Katia Anderson
Voiced by: Suzuka Ohgo (Japanese), Cynthia Geary (English), Raphaëlle Valenti (French)

Daughter of the mayor of Dropstone. She's on a secret mission in Folsense.
- Blue Blood: She is stated to be the daughter of Earl Anderson in the Japanese version. She also turns out to be related to two noble families of Folsense, being the granddaughter of Anton Herzen and Sophia.
- Curtains Match the Window: Outside cutscenes, her eyes are purple to match her purple hair.
- Family Eye Resemblance: She looks almost identical to her grandmother, Sophia, except that she has eyes similar to those of her grandfather, Anton. It's significant since getting a good look at her eyes helps Anton realize she's not actually Sophia.
- Identical Granddaughter: The resemblance between her and her grandmother, Sophia, is so strong that even Anton confuses the two. Considering that he's mistaking Katia for his estranged fiancée and he's really her grandfather, it's no wonder the poor girl gets a little distressed before she finally gets a chance to explain.
- Inconsistent Coloring: Her eyes are a green shade of blue in the cutscenes. However, outside of the cutscenes, they appear purple to match her purple hair.
- Long-Lost Relative: She is the granddaughter of Anton.
- Luke, You Are My Father: After the duel between Anton and Layton ended, she reveals herself to be the granddaughter of Anton and Sophia.
- Missing Mom: Her mother died shortly after giving birth to her, as revealed in Sophia's letter to Anton at the end.
- Raised by Grandparents: After Katia's mother died, her grandmother helped bring her up.
- Unnamed Parent: Her parents have unknown first names, only referred to as Mr. Anderson and Katia's mother.
Sophia
Voiced by: Suzuka Ohgo (Japanese - Young), Yuri Tabata (Japanese - Old), Lani Minella (English), Raphaëlle Valenti (French)

The founder of Dropstone, grandmother of Katia, and Anton's missing betrothed.
- Blue Blood: She was the youngest daughter of a noble family of Folsense.
- Cool Old Lady: While raising Katia.
- Curtains Match the Window: Has purple hair and purple eyes.
- Dance of Romance: With Anton, as seen in a painting and a Dream Sequence.
- Hand on Womb: In the flashback to when she left Anton, Sophia is briefly seen putting her hands over her stomach. Their granddaughter, Katia, reveals to him that she left him to protect their unborn child from a deadly disease that plagued Folsense.
- Mama Bear: She left Folsense to protect her unborn child from a horrible disease in the town.
- Outliving One's Offspring: She lived longer than her daughter, who died shortly after giving birth to her granddaughter, Katia.
- Poor Communication Kills: Near the end of the game, it turns out that Anton is upset because he thought Sophia had left him for another man. Understandable, as she told him she's leaving him for someone she loved more than him instead of simply saying "You're going to be a father, but I can't raise a child here. Since you can't leave, I've got to leave you."
- Posthumous Character: She died a year before the events of the game.
- Significant Double Casting: Sophia and Katia are both voiced by Suzuka Ohgo and Raphaëlle Valenti in the Japanese and French versions, which becomes significant when Katia's resemblance to her grandmother, Sophia, becomes a plot point.
- Time-Shifted Actor: In the Japanese version, she is voiced by Suzuka Ohgo as a young woman and by Yuri Tabata as an old woman.
Characters in Professor Layton and the Unwound Future
Clive Dove/Future Luke Triton
Voiced by: Shun Oguri (Japanese), Yuri Lowenthal (English), Megumi Kubota (Japanese - Child), Lani Minella (English - Child)

Luke 10 years in the future. He sends a letter to his past self and needs help. He's a Walking Spoiler, so all entries for this character are unmarked.
- The Atoner: After being defeated, he resolves to atone for his crimes.
- Big Bad: Of Unwound Future, being the true mastermind behind the game's events.
- The Chessmaster: He's such a clever and manipulative young man that he's the Big Bad.
- Disproportionate Retribution: He went off the rails after his parents were killed by an unfortunate lab accident, going so far to create a gigantic underground futuristic version of London, build a giant mobile fortress, put up a great farce, and try to blow up the real London with the machine. He attempts to justify it by saying that it's teaching the government not to disregard ordinary people since Bill Hawks managed to not only avoid responsibility for his failed time travel, but reached high office.
- Dub Name Change: From Klaus in the Japanese version.
- Feet-First Introduction: The animated cutscene that introduces him uses this trope.
- From Nobody to Nightmare: Just a young kid from London living with his folks. After they died, his own rage takes hold of him and goes on to create a machine capable of mass destruction.
- Giving Someone the Pointer Finger: Just like Layton and the others, he does this when he gets a puzzle correct.
- 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.
- Hypocrite: While the accident that killed his parents was tragic, he decides to go out of his way to make even worse destruction by attacking London with his machine.
- 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.
- Inexplicably Identical Individuals: He is able to convincingly pull off being Luke's future self, even though the two have no real explained relation.
- Ship Tease: A little bit with Flora; some of his lines for her have a flirty vibe, such as when he invites her to take his arm while walking so she can feel more secure. This could also possibly factor into why he kidnapped her, although it's not stated.
- Time-Shifted Actor: He is voiced by Shun Oguri and Yuri Lowenthal as a young man and by Megumi Kubota and Lani Minella as a child.
- Walking Spoiler: It's difficult to talk about his real personality without spoiling the time travel disaster from 10 years ago, or the fact that one of your traveling companions is the Big Bad.
- 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.
- Woobie, Destroyer of Worlds: After having his parents killed as an indirect result of greed and blind ambition, he makes it his mission to level London in retaliation. Even if his plot was ultimately foiled, he still managed to wipe out a few blocks' worth of the city regardless.
Claire Folly
Voiced by: Yoshino Kimura (Japanese), Lani Minella (English)

Layton's college sweetheart who died in an accident with a Time Machine.
- Bespectacled Cutie: A cute young woman with glasses, who was nothing but kind and supportive.
- Brainy Brunette: Very smart and a brunette.
- But Now I Must Go: At the end of the game, she 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: Zigzagged. 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.
Celeste Folly
Voiced by: Yoshino Kimura (Japanese), Lani Minella (English)

Claire's younger sister who aids the heroes in Professor Layton and the Unwound Future.
- Big Damn Heroes: She pulls the Layton team out from a tight spot while in Dimitri's research facility.
- Doomed Protagonist: It isn't until the very end that she reveals her time is short because of The Reveal.
- 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 Travel: 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.
Dimitri Allen/Dr. Alain Stahngun
Voiced by: Takaya Kamikawa (Japanese), Liam O'Brien (English)

A mysterious scientist who invents the time machine and appears to be responsible for the disappearance of Bill Hawks. He's a Walking Spoiler, so all entries for this character are unmarked.
- Affably Evil: Despite being Layton's enemy, he is relatively cordial toward him.
- All Love Is Unrequited: He loved Claire, but she didn't return his feelings.
- The Atoner: Layton describes his schemes out of "a twisted form of atonement" for feeling responsible for Claire's death.
- Disc-One Final Boss: Is usurped by Clive before the finale.
- Even Evil Has Standards: Was completely shocked when Clive revealed his ulterior motives to destroy London with a superweapon, which Dimitri had no clue about.
- Love Makes You Evil: He doesn't take Claire's death well, and everything he does in the game - kidnapping and tricking other scientists, impersonating Layton - is done out of love for her.
- Mad Scientist: He's not insane, but he's pretty amoral and knows it.
- Punny Name: Stahngun is a pun on "stun-gun", which makes sense as it's a cover for his real name, Dimitri.
- 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.
- Unfinished, Untested, Used Anyway: Tried to stop Bill from going through with the time machine test for his corporate sponsors, but doesn't get there in time.
- Unwitting Pawn: Is played like a fiddle by Clive.
- Well-Intentioned Extremist: All he wants is to save Claire, but later he does admit some of his actions may have been done out of pride as well.
Bill Hawks
Voiced by: Akihiko Ishizumi (Japanese), Christopher Miller (English)

The Prime Minister of Great Britain.
- Asshole Victim: After realizing all of the atrocities he knowingly caused, is it really hard to feel sympathy for him when he's taken hostage?
- Bitch in Sheep's Clothing: He appears as a fairly normal prime minister in the prologue (Rich Bitch wife notwithstanding), but his role in the game's backstory reveals how much of an asshole he really is.
- Corrupt Politician: A prime example of what happens when corruption and money are the prime motivations for political chaos
- Greater-Scope Villain: His actions inadvertently turn Dimitri and Clive into what they are in the story proper.
- Hate Sink: He's by far the most despicable character in the story, especially when you consider that he's the primary cause of the tragedy that set the story in motion.
- 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 the minimum, Bill won't be re-elected.
- The Sociopath: Let's see.. Causing the time traveling experiment explosion which caused ten innocent people's deaths including his colleague and Layton's girlfriend, Clare and Clive's parents just to maintain his greed, showing no remorse and having Clive arrested despite all the things he caused! such a contemptful monster to think of.

Arianna Barde

Luke's Love Interest.

Arianna's younger brother.
- Bitch in Sheep's Clothing: His profile on the official website for this game states that he's very disrespectful of others when Arianna isn't around.

- 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.
Levin Jakes
Chief of Police of Misthallery.
- Fat Bastard: Apparently he uses his immense girth to threaten people.
- Guttural Growler: Gravel is smoother than his voice.
- In-Series Nickname: Third Eye Jakes.
- Laughing Mad: Shortly after Layton meets him. This also overlaps with Evil Laugh.
- Manipulative Bastard: Evidently the real reason he's never left a case unsolved is he forces the accused into confessing.
- Obviously Evil: No one is hiding the fact he's a bad guy.
- Villain with Good Publicity: He is well respected by the town's citizens due to his reputation for solving every case he was involved in.
Black Raven
The mysterious leader of the Black Market.
- Collective Identity: Black Raven is actually children playing dress-up.
- 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.
A prehistoric Aquatic dinosoaur who hails from the Golden Garden, she is summoned by the flute and defends against Descole's Machines who seek to destroy the town. Mistaken to be the specter by Jakes and his men, which she isn't.—-
- Attack of the 50-Foot Whatever: Implied whenever her and the machine fight together, forming the illusion of a specter destroying the town

Characters in Professor Layton and the Miracle Mask
Randall Ascot
Voiced by: Yūsuke Yamamoto (Japanese), Yuri Lowenthal (English), Kanako Toujou (Japanese - Child)

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 Professor Layton and the 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. He's a Walking Spoiler, so all entries for this character are unmarked.
- Adventurer Archaeologist: Well, he was aspiring to be one. However, in the Professor Layton and the Miracle Mask credits, it seems like he's into archaeology again.
- Arranged Marriage: Was meant to marry Angela (whom he truly loved despite his over-fascination with Akbadain) before he fell in the last trap.
- Big Brother Mentor: To Layton.
- Crazy Jealous Guy: His motive for all the trouble he causes was partially because of his jealousy over Henry marrying Angela, and partially because he felt Henry betrayed every aspect of his life.
- Dub Name Change: From Lando Ascad to Randall Ascot.
- Expy: Of Hipsters in general as far as appearance goes ( Or on a similar note Eridan: Big glasses, thigh pants, purple all over, a scarf...) Well, he did go underground.
- Fiery Redhead: He's outgoing, enthusiastic and talkative in comparison with the more quiet and calm Layton.
- Love Makes You Evil: Thinking Henry stole Angela from him did not help his sanity.
- Mask of Power: He found the Mask of Chaos, which led him to the Akbadain ruins.
- Meaningful Name: Well, he certainly wears an ascot (English only obviously).
- No Sense of Personal Space: Maybe not in-game, but for the viewers...
◊
- Purely Aesthetic Glasses: His in-game profile reveals that he has excellent eyesight and only wears them to imitate a famous archaeologist.
- Retirony: He was planning to propose to Angela after the expedition.
- Walking Spoiler: Referring to him by name reveals that Randall actually didn't die in the backstory, being the true identity of the Masked Gentleman. Though, the amount of buildup they give the character in his backstory, it's almost impossible not to see that twist coming.
Angela Ledore
Voiced by: Michiko Kichise (Japanese), Laura Bailey (English)

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. However, 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.
- Blonde, Brunette, Redhead: She being the blonde, Randall being the redhead and Layton being the brunette.

- Everyone Loves Blondes: Even her brief character bio describes her as being incredibly beautiful.
- 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).
Henry Ledore
Voiced by: Seki Tomokazu (Japanese), Matthew Mercer (English), Fujiko Takimoto (Japanese - Child)

- Death Glare: He is fond of this.
- Dull Eyes of Unhappiness: A few times; once when he follows teenage Angela and Layton, and again when he discovers Randall has "died".
- Orphan's Plot Trinket: He is an orphan, and the robot that was 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.
- Rags to Riches: From Randall's servant to getting the Ascot estate.
- Rich People: In order to marry Angela he had to be rich.
- Sugar-and-Ice Personality: Can be much sweeter and loyal than he appears.
- Undying Loyalty: To Randall (although he doesn't realise it until it's almost too late).

The Masked Gentleman
Voiced by: Yūsuke Yamamoto (Japanese), Yuri Lowenthal (English)

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.

- Coat, Hat, Mask: His outfit.
- Cool Mask: The infamous "Mask of Chaos".
- Evil Sounds Deep: Significantly less so in the English dub, but still quite deep.
- Evil Laugh: A really deep one
- Mask of Power: The "Mask of Chaos".
- Power Gives You Wings: Used to make his escape on occasion.

- Visual Pun: Related to his true identity: Randall Ascot is wearing an ascot.
Alphonse Dalston
Voiced by: Binbin Takaoka (Japanese), Troy Baker (English)
- Dub Name Change: From Alford Dalston, in Japanese.
- Jerk with a Heart of Gold: Dalston has a reputation for being standoffish and rude, but he genuinely cares about the people of Monte D'Or. Layton also reveals that Dalston has a particularly large soft spot for animals. Once Layton clears Dalston's name, Dalston genuinely thanks him and offers to help him in the investigation in any way. The player can also choose to have Layton and Dalston sit down and catch up, which ends with Dalston giving Layton a scale model of his mansion. Brusque though he may be, Dalston is a good man deep down.
- Pet the Dog: Close to the circus tiger.
- Red Herring: The first suspect for being the Masked Gentleman, and the most easily ruled out, especially because he couldn't fit into the costume.
Detective Inspector Leonard Bloom
Voiced by: Yuki Kaji (Japanese)
A detective who is sent over from London to help with the Masked Gentleman Case, and later, deals with the robbery of the museum.
- Clasp Your Hands If You Deceive: He does this during the confrontation in Scotland Yard.
- Dub Name Change: From Ronald Bluemile.
- Graceful Loser: He may be slightly arrogant to everyone but after being deduced as the Targent mole by Layton. He's willing to surrender quickly rather than fight back.
- Hidden Agenda Villain: He is gathering information for Bronev.
- 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 Professor Layton and the Miracle Mask, but Layton doesn't get to expose him until Professor Layton and the Azran Legacy.
Characters in Professor Layton and the Azran Legacy
Aurora
Voiced by: Shiori Katsuna (Japanese), Jo Wyatt (English)
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.

- Last of Her Kind: The last Azran... Golem actually.
- MacGuffin Super-Person: Targent and Professor Layton's group spend a few hours of Professor Layton and the 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 Means 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.

Voiced by: Atsuro Watabe (JA)
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.
- Beware the Nice Ones: If you mention Targent around him, he will quickly get angry which is understandable because in his childhood, Targent abducted his parents and may be implied to be responsible for his wife and daughter's deaths, which made him create his alter ego denoting his vengeful personality as Jean Descole.
- Cannot Tell a Joke: As demonstrated in the group's travels to Phong Gi.
- Doting Parent: Occasionally has shades of this towards Aurora, even becoming...
- Dub Name Change: From Foster Sahaiman in Japanese.
- 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.
- Nice Guy: Like Layton, Sycamore is your all-around gentleman who's quite pleasant to be around with which make his alter ego as Jean Descole, Layton's arch-rival all the more unbelievable.
- Older Than He Looks: He looks like he could a recent graduate but is actually older than Layton, making him somewhere from his late thirties to early forties.
- Outliving One's Offspring: He mentions in passing that his daughter would be about the same age as one villager if she were still alive.
- Purely Aesthetic Glasses: The guidebook mentions that his glasses are for show.
- Significant Double Casting: He and Jean Descole are both voiced by Atsuro Watabe, which becomes significant when it turns out that they're one and the same.
- 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.
- Two Aliases, One Character: He and Jean Descole are the same person.
Leon Bronev
Voiced by: Masachika Ichimura (JA), Timothy Watson (English)
A mysterious man who knows both Layton and Descole; little is known about him. He is the commander of Targent, a shadowy organization trying to obtain the Azran Legacies. He's a Walking Spoiler, so all entries for this character are unmarked.
- Authority Equals Asskicking: Not only is Bronev the leader of Targent, he is also a very capable fighter, as seen at the end of Miracle Mask when Descole tries to take him down, only for Bronev to dodge Descole's punch and knee him in the ribs for his trouble.
- Badass Army: The Targent is this, feilding a wide variety of Tanks, Armored Vehicles, and even Helicopters.
- 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 Professor Layton and the Azran Legacy.
- Beard of Evil: Notably clean-shaven in flashbacks to before he became boss of Targent.
- Big Bad: Of Professor Layton and the 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 Professor Layton and the Miracle Mask, but doesn't directly interact with Layton until Professor Layton and the Azran Legacy.
- Even Evil Can Be Loved: Although Bronev himself doesn't comment on their relationship, Emmy- or rather, Emmeline- does seem to care a lot about him. So much so that all she wants is for him to finish everything so he can return to being the kind person she remembers him as, and hopes the professor can also help finally bring him to his senses. She believes that despite his all-consuming obsession with the Azran, he's truly a good person.
- Dub Name Change: From Broneph Rainel.
- Faux Affably Evil: Bronev isn't above speaking like a polite gentleman like Layton depending on the situation but we've already been introduced to him as a ruthless and despicable megalomaniac with fewer regards for his subordinate's wellbeing, and willing to use pragmatic methods to get what he wants.
- 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.
- Luke, I Am Your Father: He's Layton and Descole's father, though Layton doesn't find it out from him.
- My God, What Have I Done?: At the end of Professor Layton and the Azran Legacy, when he unwittingly unleashes a doomsday device in his thirst for the Azrans' power. He ends up becoming shell-shocked for much of the climax.
- Parental Substitute: He took Emmy in and taught her all she knows, so she calls him "Uncle Leon" out of endearment and works for Targent. It's never outright stated if they are actually family.
- Parents as People: In Layton and Descole's childhood flashback, he was a loving father and husband but as a archaeologist, it's implied that he put priority with studying the Azran civilization over his family which came to bite him horrifically when Targent appeared and abducted him and his wife, Rachel leaving the two boys orphaned.
- 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.
- Sinister Shades: His sunglasses only make him appear more suspicious. After taking them off, he looks less sinister and more like a broken man.
- Tragic Villain: Bronev, for all of his less than moral actions, is actually an idealistic person who wants to solve the Azran Legacy for the good of mankind and was the good husband and father of Descole and Layton before Targent abducted him and his wife, Rachel. Seeing her passed away from an illness while in captivity along with his unstoppable obsession with the Azran civilization made him lose his humanity which lasts until the end of Professor Layton and the Azran Legacy when he finally comes to his senses and expresses remorse for the events he caused.
- Used to Be a Sweet Kid: Near the end of Professor Layton and the Azran Legacy, after realizing his cruel actions activates the Weapon of Mass Destruction and revealing to be the long-lost father of Descole and Layton, we are treated to a flashback of him as a child who found an ancient artifact one day by himself and became an archaeologist like his son and Layton. After he's kidnapped by Targent and his wife dies while they're in captivity, his obsession with finding the Azran legacy turns him into a twisted and selfish man.
- Walking Spoiler: He is not only the Big Bad, but Layton and Descole's father, Emmy's Honorary Uncle and boss, and a somewhat more sympathetic character than he initially seems.
- 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.
- Chess Motif: They were named Bishop and Rook in the UK.
- Dub Name Change: Specifically Macaw, from Swallow.
- Even Evil Has Standards: Macaw decides to leave Targent after deciding that killing people is a bit much for him. Robin soon follows.
- Evil Duo: Always seen together and have matching names (Chess in UK and birds in the US, Spain and Japan).
- Hidden Depths: Macaw seems as incompetent as Robin at first glance, but Layton deduces that he actually doubts the morality of the agency.
- Mook–Face Turn: Toward the end of the game, they quit working for the organization.
