This is the character list for Ys IX: Monstrum Nox. For entries about Adol Christin, Dogi and characters from other installments, see here.
- Artificial Humans: Everyone except Doll turns out to be this.
- Brought Down to Normal: At the end of the game, the destruction of Draupnir's Egg results in monstrums' losing their powers and free to live out their lives as regular human beings.
- The Chosen One: Aprilis specifically chose them to fight against larva. Justified as it is later revealed that they are created for this very specific purpose from the very beginning and with the exception of Red King and Doll, Aprilis simply drafted them once they grew old enough.
- Cloning Blues: All monstrums except Red King and Doll are revealed to be clones of the historical figures from Balduex 500 years ago.
- Closed Circle: None of them is allowed to leave the city of Baldeux.
- Conveniently an Orphan: All of them except Adol and Doll are adopted and have no memories of their parents. Justified as they are artificially created, meaning they never had real parents to begin with.
- Heroes With Bad Publicity: Despite fighting in secret to protect Baldeux from the threat of Grimwald's Night, they are wanted by the authority for various reasons.
- Impossibly Cool Clothes: Their clothes in general look more like fancy ballroom costumes than practical battle gears.
- True Companions: Subverted at the beginning as Aprilis more or less forced them into the role of fighting against larva so they only get together when Aprilis summons them and there is no real bond among them. Eventually becomes a straight example as Adol, while investigating the mystery behind Grimwald's Night and Baldeux city, helps other monstrums with their own problems and they start cooperating on more personal level.
White Cat/Kilysha Pendleton
See Kilysha's entry in People of Baldeux City for the tropes associated with her regular self.
- Cat Girl: Events show that her tail and cat ears are indeed real.
- Fragile Speedster: Her attacks are fast but she cannot take many hits. It is partially mitigated by the fact that her weapons come with natural evade rate.
- Just Like Robin Hood: Her M.O. She steals from the rich and drops the loot for the poor to pick up. Deconstructed in that this only led to slum people's becoming reliant on her instead of making an effort to improve their lives.
- Nice Hat: She sports one.
- Wall Run: White Cat's monstrum power lets her run straight up a wall without breaking a stride, as if gravity didn't exist.
- Wolverine Claws: Her weapon of choice.
- Blood Knight: He really loves fighting. In fact, at the beginning of Chapter 2, he even tries to pick a fight with Adol for little to no reason, only to be restrained by Aprilis as monstrums cannot fight each other.
- Blow You Away: Many of his skills feature a wind element.
- Dual Wielding
- Duel Boss: Adol can fight him in one of the sidequests during late-game.
- Hidden Depths: He is actually a great painter.
- No Challenge Equals No Satisfaction: Because of his many talents, he found life to be incredibly boring. In fact, this is the main reason for his Blood Knight tendencies as he hopes to find someone who can provide challenge and make him feel alive.
- Say It with Hearts: He does this whenever the party faces powerful foes.
- Token Evil Teammate: Hawk is the only monstrum who actively causes trouble in Baldeux for purely selfish reason.
- Emotionless Girl: She even says as such. Justified since her original self is an actual antique doll so she does not have understanding of how emotions work. Subverted later on as she starts remembering more about her past.
- Mysterious Past: With the dose of Laser-Guided Amnesia. She has no memory of how she has come to gain sentience. She also knows that there is something she wishes to find desperately but has no idea what it actually is.
- Nice Hat: Even bigger and fancier than the one White Cat wears.
- Rollerblade Good: Her shoes have wheels on them. This also makes her one of the fastest among monstrums.
- True Sight: Her monstrum power. It allows the party to see hidden objects or weak points of enemies.
- Tsundere: Despite her claim that she has no emotion, she cares a lot about the old couple who runs the antique shop where she "lives". In Chapter 4, she asks for the party's help in retrieving the saintess statue stolen by fake monstrums as the theft makes the old couple distraught.
- Whip Sword: Her weapon of choice.
See Yufa's entry in People of Baldeux City for the tropes associated with her regular self.
- Beauty Mark: Has one on her left cheek, which is one of many clues that her true identity is Yufa.
- The Big Girl: Her role in the team.
- Boobs of Steel: The most physically oriented female monstrum is appropriately the most well-endowed one.
- Drop the Hammer: Her weapon of choice.
- Interface Spoiler: Listening to her voice makes it pretty obvious that she and Yufa are one and the same.
- Mighty Glacier: She's a slow, hard hitter and her HP growth is one of the highest among the party.
- Spin Attack: Some of her skills have her do this.
- Super Strength: Her monstrum power. It allows her to break certain obstacles and remove enemies' protections.
- Bad Powers, Good People: His monstrum power involves shadows and his skills are darkness-based. Yet, he is one of the monstrums who fight against larva to protect the city of Baldeux.
- Casting a Shadow: His skills are primarily darkness-based.
- Happily Adopted: His adopted parents love him like a real son.
- Ill Boy: His true self is bound to a wheelchair and is expected to have a short lifespan, which has left him understandably bitter. It is the reason why Renegade does not mind the curse of Grimwald's Night since it at least allows him to be mobile and healthy while he is transformed.
- Long-Range Fighter: He yields a wand and his normal attacks and skills consist of shooting projectiles from it.
- Squishy Wizard: He can attack from far and his damage output is high as his weapon comes with extra crit rate but he cannot take many hits.
- Your Days Are Numbered: The main reason for his pessimistic attitude. Subverted in the end where his adoptive father manages to find the cure and he becomes healthy enough to walk.
- Artificial Limbs: She has an artificial arm and leg.
- Body Backup Drive: She has other spare bodies ready in case something happens to her current one.
- Covered with Scars: Due to fighting against the threat of Grimwald's Night alone for past 15 years.
- Jeanne d'Archétype: She was this during the Hundred Years' War, right down to her humble origin, receiving divine vision to fight for her country, and tragic untimely death due to political machinations.
- Mommy Had A Good Reason For Abandoning You: Due to sudden deaths of previous monstrums and disappearance of her partner Zora fifteen years ago, she had to send the current monstrums except Doll and Red King away for adoption instead of raising them herself.
- Parental Substitute: She was this to previous generations of monstrums for past 500 years.
- Really 700 Years Old: By transferring her memories and soul to another body whenever her current one dies, she has been able to live on for past 500 years.
People of Baldeux City
- Aloof Big Sister: She is this to Kilysha. Eventually, she becomes Cool Big Sis after Kilysha's Character Development.
- Always Someone Better: Kilysha feels this way towards her.
- Awesome by Analysis: During the first meeting with Adol (who is wearing a disguise), she quickly deduces Adol's true identity. Also, from Adol's reports about White Cat, she figures out that White Cat is none other than her sister Kilysha.
- Damsel in Distress: In the late game, she is kidnapped by Celestrial Church Knights.
As the monstrum White Cat, she is actually responsible for stealing her own sales and giving it to the poor. She and her father Riche once visited the slums of Baldeux for business. Seeing how miserable people's lives were in that area, she felt giving her sales is the least she could do for them. Unfortunately, this has led to slum people's becoming dependent on her rather than doing anything to improve their lives, which puts her into a dilemma.
- Crash-Into Hello: Her first meeting with Adol.
- Did I Just Say That Out Loud?: In her max approval event, she accidentally blurts out that if the curse that prevents Adol from leaving Baldeux is magic, then she wishes it would never go away. Needless to say, she is extremely embarrassed afterwards.
- Happily Adopted: While there is some friction between her and her adopted family, it is clear that they care a lot about her.
- Luminescent Blush: Just like Laxia from the previous game, she does this whenever she feels embarrassed, is praised or teased by Adol.
- Nice Girl: Very kind hearted girl without any mean bone in her body.
- Shrinking Violet: This, along with her Nice Girl personality, causes problem with rest of her family as she struggles with following the family motto, which is to ruthlessly defeat any competition with capital gains.
- Ship Tease: Has many of these with Adol as she develops a huge crush on him.
- Start My Own: At the end of Chapter 2, she breaks away from the Pendleton company and opens a small flower shop at the slums in order to find more constructive way to help people instead of simply handing free money.
Riche PendletonThe head of the Pendleton family, which has a major influence in Baldeux. Shrewd in commerce, he gained enormous capital power by monopolizing the mining rights to the mines of nearby regions. He will utilize any means necessary for business and profit gains, and always takes a high-handed attitude, which makes many residents discomforted by his presence.
- Stern Teacher: He was this to his daughters.
- Sugar-and-Ice Personality: Eventually he is revealed to be like this as he shows that he cares a lot about Kilysha underneath that stern exterior.
- Tough Love: He is strict to his daughters in hopes that they will grow into capable merchants worthy of the Pendleton name.
- Beauty Mark: Has one on her left cheek, which is a hint that she is Raging Bull's true identity.
- The Ditz: While she isn't dumb by any means, she is lacking in some common knowledge compared to others, such as not knowing the current Romun emperor's name and being the only major character who completely falls for Salady's scheme to give sleeping potions to everyone in Dandelion.
- Happily Married: To Felix at the end of the game.
- He Is Not My Boyfriend: She insists that Felix is not her boyfriend but everyone can see they are an item.
- Mama Bear: She will not let any harm come to her siblings and Felix even if it means blowing her cover.
- Nice Girl: She is a genuinely kind-hearted woman who cares about her family.
- Team Mom: She is this and Parental Substitute to her siblings, who are not related to her by blood.
- Ambiguously Gay: While he has all the trappings of a Camp Gay man, he doesn't quite show romantic attraction to anyone, male or female. The most he does is compliment Dogi's muscles.
- Camp: Extremely flamboyant and effeminate.
- Hidden Depths: He used to be rather successful gladiator.
- Nice Guy: Always happy to lend an ear and give advices to those who ask for them.
- Fallen Princess: She is actually Princess Eleonore of the kingdom of Glia.
- Happily Adopted: Parks adopts her as his own at the end of the game.
- You Killed My Father: She wants to assassinate Lindheim as she believes Lindheim is responsible for the war that resulted in her father's death and destruction of her kingdom. Subverted as it is later revealed that Lindheim was not only strongly against the war between Romn and the kingdom of Glia but he also tried to protect the royal family of the Glia kingdom in the aftermath.
- Friend in the Black Market: He is called a "Black Marketer" for a reason.
- Hidden Depths: He used to be a troubleshooter who worked for the kingdom of Glia from shadows. Also, he is quite capable of fighting as he has no problem defeating some Celestrial Church knights on his own.
- Last Request: His sidequest reveals that he has been working towards fulfilling this from none other than the late king of Glia, who asked him to find and destroy the royal seal of Glia so it may not be used for ill purposes.
- Loyal Animal Companion: His partner owl, Arthur.
- Walking the Earth: Inspired by Adol, he decides to do this in the end.
- Distressed Dude: Adol's party first meets him and his sister when the siblings are dragged into Grimwald's Night, prompting the party to rescue them.
- Ultimate Blacksmith: His goal is to become a blacksmith as good as his father. He is the one who forges Adol and his party's ultimate weapons and armors in this game.
- Anti-Frustration Features: She acts as this in regards to shopping since she will sell most items from shopkeepers in the city once Adol finds them so players can just go to her for shopping instead of remembering what each merchant sells.
- Mask of Power: It makes larva from Grimwald's Night invisible to her, allowing her to function as a normal human being.
- Undying Loyalty: To Baran.
As she helps out another doctor she is acquainted with, she seems to be looking for a certain something. She later makes an appearance at the bar Dandelion where Adol and Dogi are in hiding.
- Ambiguously Brown: Her racial background is unclear.
- Classy Cat-Burglar: While her skills as a doctor are genuine, she turns out to be one of these as her true goal is to find treasures rumored to be hidden in Baldeux.
- Labcoat of Science and Medicine: Wears this befitting her profession as a doctor.
- Slipping a Mickey: In her side quest, she does this to the people at Dandelion as she thought the treasures she is looking for are hidden below the bar. She later finds them but they turn out to be in Grimwald's Night guarded by large number of larva so she is only able to take one tiny jewel.
- Stripperific: Her outfit underneath the Labcoat of Science and Medicine.
- Thrill Seeker: She is more interested in the thrill of finding treasures than the treasures themselves.
- Walking the Earth: She does this at the end along with Xavier, planning to find treasures in other regions.
Celestrial Church Knights
LucianThe second-in-command of the Celestrial Church knights, a wing of the Hieroglyph church located in the Glia region. They are dedicated to missionary work and the preservation of the provinces public order. However, noticing strange arrests that the knights in the order have been making recently, he tried to take up the issue with Chatelard, only to get forcibly sent away from Baldeux under the guise of vacation. Thankfully, Adol and his party intercept this and Lucian joins them in order to find out what Chatelard is planning.
- Defector from Decadence: He does not agree with how Chatelard runs the order and joins monstrums to investigate what Chatelard is scheming.
- Hair of Gold, Heart of Gold: A noble blond-haired knight who is devoted to protecting the city of Baldeux.
- Number Two: Was this to Chatelard in the Celestrial Church Knights until he started questioning Chatelard.
- Reassigned to Antarctica: Would have happened to him if monstrums did not intervene.
- Bald of Awesome: He is a man dedicated to keeping peace and order in the city of Baldeux.
- Frontline General: He has no problem fighting alongside his subordinates.
- Hero Antagonist: While he initially opposes monstrums, it is due to their actions' causing public disorder, which goes against what he fights for.
- Reasonable Authority Figure: He genuinely wants to keep the peace in the city and stars questioning Chatelard once Chatelard starts taking things too far, getting jailed in the process.
- Blue Blood: As a member of the Romun nobility and its clergy.
- Defector from Decadence: Just like Griselda and Leo from Ys: Memories of Celceta, he does not approve of Romn's corruption and its militant expansionist policies at all, as he was strongly opposed to the war between Romn and the kingdom of Glia and did everything he could to minimize the bloodshed.
- Good Shepherd: In addition to being the governor-general, he is also a cardinal of the Hieroglyph Church.
- Quest Giver: He is the one who rewards Adol for the Cartography Sidequest in this game.
- Reasonable Authority Figure: As the governor-general of the Glia region, he is this as he wishes to improve the living conditions of the people in the Glia region unlike the previous one who only cared about lining his own pockets. In fact, at the end of the game, he reveals that he once worked at his father's mine for two years without revealing his identity just so he could understand commoners better.
- The Reveal: He is the governor-general of the Glia region who has gone missing lately, which allowed Chatelard to slowly take over the city in secret during his absence.
- Walking Spoiler: Knowing his true identity spoils some significant parts of plot of Ys IX.
- Smoking Is Cool: As the leader of La Résistance, she sure loves her cigars.
- La Résistance: She led the rebellion against the previous governor-general sent by Romn, who was only interested in lining his pockets.
- Luxury Prison Suite: She is in this when monstrums come to see her. In fact, she has little to no problem escaping from the prison as wardens are indebted to her.
- Reasonable Authority Figure: She is willing to work with the current governor-general to make Glia a better place for everyone and tries to prevent more extreme members of her organization from causing unnecessary bloodshed.
- Bad Guys Do the Dirty Work: While he himself was never a true villain, in the late-game sidequest, he destroys the remaining homunculi that Chatelard created so Adol and his party do not have to dirty their hands.
- Cloning Blues: He is revealed to be a clone of the current Romun emperor.
- Disappears into Light: He perishes in this manner after Adol fatally stabs him as per his request.
- Forced into Evil: He is tasked with making sure the real Adol Christin does not escape from the prison but has absolutely no choice in the matter due to being forced to obey Zora's commands.
- I Cannot Self-Terminate: Near the end of the game, he reveals that this is the case for him and asks Adol to destroy him to make sure no homunculus remains alive to cause chaos.
- Agent Scully: She considers Adol's stories as complete nonsense.
- Butt-Monkey: Due to Adol's being a Weirdness Magnet, she ends up encountering all sorts of supernatural happenings throughout the game, which usually ends with her running away in disbelief.
- Inspector Javert: Throughout the game, she keeps trying to recapture Adol and send him to the capital of Romn for further questioning only to fail every time.
- Came Back Wrong: Xavier was originally one of the historical figures from Baldeux 500 years ago, but something went wrong in the process of reviving him and he came back as a roo instead of human. This is also the reason why he can speak human language just fine and does not contain the word -ru in his name.
- Excalibur in the Rust: Played with. His sidequest at the endgame involves finding the holy blade he used to yield 500 years ago as a human. By the time Adol and his party find it, they discover that the blade has rusted with its handle's being the only usable part. However, the handle works as a powerful accessory, increasing the power of skills by 20% and giving 40% natural crit rate to whoever equips it.
- Jerk with a Heart of Gold: He may act condescending towards people but he ultimately means well. Later in the game, he even distracts enemies in order to buy the real Adol time to escape from the prison.
- Meaningful Name: Unlike other roos in the series, his name does not contain the word -ru or -roo. That's because he wasn't a roo to begin with.
- Walking the Earth: He does this with Salady at the end.
- Was Once a Man: See the Came Back Wrong trope above.
Spoiler CharactersDue to the nature of the following characters, spoilers are unmarked to avoid redundancy.
Or at least that is how it initially looks like. It is later revealed that this Red King is in fact a homunculus of the real Adol Christin created by Zora. The real Adol Christin, whom the player periodically controls for small segments of Baldeux prison, remains imprisoned for majority of the game.
- Cloning Blues: This "Adol" players control for much of the game is a clone of the real Adol Christin.
- Fashionable Asymmetry
- Flash Step: His monstrum power Crimson Line works like this, allowing him to instantly close in distance between him and an object/enemy.
- Foreshadowing: After escaping from the prison and meeting Dogi, Dogi notices something is slightly off with "Adol" but pays no more mind to it.
- Fusion Dance: He does this near the end of the game with real Adol Christin as his body is running out of time and Zora needs to be stopped.
- Mark of the Supernatural: His literal red left hand certainly looks the part and he uses it to activate his monstrum power.
- Tomato in the Mirror: See Cloning Blues above.
- Walking Spoiler: His status as a clone of Adol is one of the biggest plot twists in the game.
He seems to take an interest in Adol and his experiences as an adventurer throughout many different regions. In fact, he is the one who apprehends Adol and throws him into the prison at the beginning of the game. Throughout the game, he is shown to have more knowledge about monstrums and the prison city than he lets on.
It is later revealed that he used to be the general of the kingdom of Glia, which was destroyed by the Romun empire eight years ago. His goal is the liberation of the Glia region from the Romun control and he is willing to do anything to make it happen.
- BFS: His weapon of choice. Later becomes One-Handed Zweihänder in his transformed state.
- Climax Boss: The boss fight against him comes after major reveals and the story goes to its final chapter afterwards.
- Disappears into Light: This is what makes him realize that he is a clone of the real Chatelard who died eight years ago.
- Face Death with Dignity: Realizing that he is a clone of the real Chatelard and that the original died along with his comrades eight years ago, he dies content that he will finally get to join them.
- The Heavy: While Zora is Big Bad, it is Chatelard's scheme to free the Glia region that drives the plot for majority of the game.
- Master Swordsman: He is powerful enough to take down Hawk even while Hawk is in his monstrum form. He also manages to fatally wound Aprilis (or rather her current body) right in front of the party without anyone's catching his movement.
- One-Winged Angel: In his boss fight, he transforms into a blue demon with the power of alchemy.
- Survivor Guilt: Part of his motivation for wanting to liberate the Glia region by any means comes from being the only survivor in his unit during the war against the Romun empire. At least that's what he believes.
- Tomato in the Mirror: The late game reveals that this Chatelard is a homunculus of the real one, who did indeed die along with his comrades eight years ago during the war against the Romun empire.
- Unwitting Pawn: To the alchemist Zora.
- Verbal Tic: He often grades others' actions and replies on the spot, like saying Hawk's skill is 40 out of 100 after engaging in battle with him.
- Walking Spoiler: It is difficult to reveal anything about him without spoiling major plot points in the story.
- Well-Intentioned Extremist: He wishes to free the region of Glia from the Romun control and build a strong country. Unfortunately, he goes about it by making clones of extraordinary people across the world in order to raise an army.
ZoraThe alchemist who is the main villain of the game. He is the one who provides Chatelard with knowledge and means to create an army of clones from extraordinary people across the world. As it turns out, he has his own reasons for doing so, which go beyond liberating the Glia region.
- Big Bad: As the man behind Chatelard, he is responsible for much of the chaos in the game.
- Didn't Think This Through: While it is true that Adol's memories contain godlike beings who could neutralize the threat of Grimwald's Night, Zora seems to have neglected the fact that most of those beings were threats to the entire world and were hardly controllable by human hands, which was generally the reason why Adol ended up fighting them. Sure enough, Atola, the being created from those memories, promptly goes out of control and attempts to go about his task in most destructive way possible.
- The Extremist Was Right: While his scheme to create the divine being from Adol's memories ends up in disaster, it is instrumental in ending Grimwald's Night permanently as benevolent entities from Adol's previous adventures, once freed from Atola, help Adol destroy Draupnir's Egg, the cause of Grimwald's Night.
- Fallen Hero: He was once the second-in-command of Hrotsvitha, who saved the kingdom of Glia from Brittai's invasion 500 years ago.
- Karma Houdini: While Aprilis is shown to be taking care of/monitoring him during the ending, he is notably the only Big Bad in the series who survives the game he appears in. Likely has to do with the fact that his goals were genuinely noble and he did not go as extreme as other villains in the series did.
- Kick the Son of a Bitch: While he experimented on many people for his goals, some of them were unpleasant people such as the general whose cowardice resulted in the destruction of the kingdom of Glia and the priest who interrogated and burned Hrotsvitha at the end of the Hundred Years' War.
- Love Makes You Evil: The main motivation behind his wish to stop Grimwald's Night at any cost is that he is sick and tired of seeing his beloved Aprilis/Hrotsvitha getting hurt and die.
- Mad Scientist: Has no problem experimenting on people if it helps him achieve his goals. Played more sympathetic than most examples of this trope in that his goals are genuinely noble.
- Man Behind the Man: He used Chatelard in order to collect extraordinary people across the world.
- Master of Disguise: He takes on various disguises to interact with the party throughout the game before revealing his true self.
- Number Two: He was this to Hrotsvitha durig the Hundred Years' War.
- Really 700 Years Old: Through the use of Body Backup Drive, he was able to live on for past 500 years.
- Well-Intentioned Extremist: His goal is identical to Aprilis but unlike her, he is willing to go at any length to stop Grimwald's Night for good.
Atola Nox Philius
- Final-Exam Boss: His second form, Anima Ergastrom, requires the use of nearly all monstrum abilities to defeat.
- Gone Horribly Right: Zora wished to create a godlike being powerful enough to end the threat of Grimwald's Night permanently. Zora got it alright.
- Light Is Not Good: His initial form looks like a winged angel similar to the Eldeen. Unfortunately, that's where similarities end as other tropes about Atola show.
- Mismatched Eyes: One of his eyes is glowing.
- Murder Is the Best Solution and Omnicidal Maniac: If his intention to destroy all humans in Glia is anything to go by.
- One-Winged Angel: Turns into a grotesque abomination once souls inside of him go completely out of control.
- Power Glows: He has a Power Tattoo on his chest that glows in emerald green.
- Storm of Blades: He can summon large spectral swords to swing or throw them at the party.
- Turned Against Their Masters: He stabs Zora in the back once Zora declares him a failure and attempts to destroy him.
