Nathalie Sancoeur

## Nathalie Sancoeur(a.k.a. Mayura)

* Nathalie
* Mayura
* Catalyst
* Safari

**Nathalie Sancoeur** is a former treasure hunter of magical objects and Gabriel Agreste's assistant who manages his fashion work, his mansion, and takes care of his son Adrien.

In "Catalyst", which is part of the "Heroes' Day" special, Nathalie is voluntarily akumatized by Hawk Moth into **Catalyst**, a power-enhancing supervillain.

In "Mayura", in order to save Hawk Moth from the French Miraculous superhero team, Nathalie uses the Peacock Miraculous. When the Peacock Miraculous is inhabited by Duusu, she becomes **Mayura**, the secondary antagonist of Miraculous: Tales of Ladybug & Cat Noir. She helps Hawk Moth by creating allies for akumatized villains.

In "Ladybug", Nathalie is re-akumatized into Catalyst in an attempt to help Hawk Moth, but due to being ill, she is deakumatized shortly after. Later, Mayura amokizes herself and her dedication forms the Ladybug-themed sentimonster.

Due to using the damaged Peacock Miraculous, Nathalie was left very weak and stuck in bed, but was eventually well enough to get back to work, with the aid of robotic leg braces to help her walk.

## Appearance

### Physical appearance

Nathalie stands at an average adult height. She has pale skin, bluebell eyes and black hair with a streak on the left side of her head that is dyed a red color. Her hair is pulled back into a bun with the hair on top with a piece of it hanging over her face.

### Civilian attire

Nathalie has glasses with black and red striped frames and she wears very pale blue eyeshadow. She wears a red turtleneck sweater, a black dress jacket, black pants, and black medium-heel shoes. She also has round creamy-white earrings. From "Risk (Shadow Moth's Final Attack - Part 1)" and onwards she wears Emilie's wedding ring which was entrusted to her by Gabriel.

### As Mayura

Mayura's skin is light indigo and she has short, strong blue hair, part of which curls up underneath her left eye. Her eyes have light magenta irises and vivid violet sclerae, just like her kwami, and there is black liner around her eyes, resembling glasses.

She wears a peacock-feather-like cocktail hat, which is blue and tear-shaped with a light pink mark in the center and a light blue, translucent veil over her right eye. She wears a blue coat with a fuzzy blue collar and sleeves that end in a point on the back of her hand. The coat appears to have a set hexagonal texture. The bottom of the coat has a front-slit, and the end of the back has several rounded points with dark blue, light-pink-centered spots, resembling a peacock's tail feathers. The rounded points are edged with translucent light blue material. Underneath the coat, she has translucent indigo tights on her legs and a pair of high-heeled boots.

She wears the Peacock Miraculous in the center of her upper torso and holds a blue hand fan.

### As Catalyst

Catalyst has pale, light grayish blue skin. Over her head, while leaving her mouth exposed, she wears a dark grayish cornflower blue helmet with a red visor with dark grayish cornflower blue edges and a red spike pointing towards the back of her head. Catalyst also wears a dark grayish cornflower blue dress suit with pointed shoulders, including a strong red front and swan neck collar that features a red downward-arrow-shaped section in the center. The sleeves cover her entire arms, with the tips of her fingers fading into red. Also, Catalyst has pocket-like ridges on each side of her hips, and her pant legs come down to her feet, having red high-heels, soles, and tips.

## Personality

Nathalie is a serious and formal woman who works very diligently as Gabriel Agreste's assistant. She has a cold and distant demeanor as she doesn't openly show her emotions around others most of the time. Her will is strong, remaining unfazed even when people of greater authority like Audrey Bourgeois yell at her, knowing the aforementioned couldn't affect her and smiled with satisfaction after the event. Objective, sensible, and understanding, Nathalie can reason with both Gabriel and Adrien whenever they are acting inconsiderately or emotionally, sometimes in relation to each other. While not warm, she can be cordial and polite.

However, in situations where she is dealing with Gabriel, Nathalie becomes nervous, being afraid to disappoint him. Her desire to be on his good side leads her to unfair actions, such as giving Adrien a birthday gift and claiming it is from Gabriel when it is actually from Marinette. Despite this, she doesn't always obey Gabriel's orders or has acted rebelliously, as seen in "Oni-Chan" when she let Lila enter with the intention to help Adrien, not knowing she was being manipulated in that moment.
This was seen again in "Ladybug" but to a more dangerous step, as she used the then damaged Peacock Miraculous despite her more delicate condition.

Although she doesn't usually openly show it, Nathalie desires what is best for the Agreste family and often hopes that Gabriel would pass more time with Adrien instead of acting as a villain. However, her concern is limited to the Agreste family only and she doesn't seem to care about the other Parisians' well-being. In fact, Nathalie obeys Gabriel's orders and helps him with his plans with fierce dedication and loyalty, no matter how morally wrong they are, so he could accomplish his goal and thus finish his time as Hawk Moth. She takes sadistic joy in fooling the heroes into thinking they can win.

Even though she has a cool and calm demeanor, Nathalie can lose her temper on occasion and would disregard any detrimental consequences as a result. She can get frustrated by the fact that her boss is failing and even goes as far as letting herself be harmed in order to success, which actually make many plans successful. Despite this, Nathalie admits that the job is sometimes too much.
As shown in "Ladybug", Nathalie apparently sees the sentimonsters she creates as Mayura only as tools to do her bidding and has no qualms with revoking their amoks if they defy her as she did with the Ladybug sentimonster, effectively murdering a living, sentient being and showing no remorse for having done so.

However like Gabriel, she didn't think things the whole through like in "Evolution", as they both didn't fully understand the consequences of time travel.

## Abilities

### As a civilian

Nathalie is an effective assistant, able to take care of Gabriel's fashion work, look out for superheroes and potential akuma victims, and organize Adrien's strict schedule. Additionally, Nathalie has capable teaching abilities, as shown during Adrien's homeschool period.

Like her boss, Nathalie is insightful and cunning. She had the idea to use Lila's lying ability to cause stress to Chloé, who indirectly caused a very powerful akumatized villain and caused eventual doubt in the former superheroine. In the episode "Félix", she displayed notable unarmed combat skills.

Her plan of impersonating Ladybug with the Sentimonster Ladybug to get the Cat Miraculous had a considerable chance to succeed, but ultimately failed.

Throughout most of her appearances, Nathalie has proved to be talented with the element of stealth. She is good at hiding herself and take advantage of distractions to sneak without anyone noticing. This ability allowed her to evade professional guards and steal Fu's tablet with the deciphered spellbook pages.

### As Mayura

Mayura has enhanced physical characteristics: speed, strength, and agility. She showed considerable hand-to-hand combat skills against more experienced combatants.

However, her illness started to weaken her physical prowess even in her enhanced state.

Mayura is able to infuse a feather plucked from her hand fan with her power, transforming it into an amok, and send it out to possess an object owned by a chosen target, with whom she can communicate telepathically. While she is communicating, a blue curved peacock mask appears in front of her and her target's faces. Her actions will then give an emotion from her target a physical form of that person's choosing, which would act as the target's ally until recalled via a snap of her fingers, which destroys it.

Even if she didn't create them, Mayura can either bring back to life dormant sentimonsters or destroy them through their amoks. This ability was first seen in "Feast".

### As Catalyst

Catalyst has the power to multiply/enhance/augment/increase someone's powers; infusing scarlet energy into an object belonging to her target, similar to an akumatized object. When affected, the person gains a red-colored outfit. In Hawk Moth's case, this power allows him to akumatize multiple butterflies and transform multiple people at once. Catalyst can also communicate with the person she enhanced, during which a red sharp-edged butterfly mask appears in front of both of their faces, similar to Hawk Moth.

## Relationships

### Gabriel Agreste/Hawk Moth

Nathalie works professionally as Gabriel's assistant, making sure to take care of all of his requests and looks after his son. Occasionally, she tends to get nervous when dealing with him, such as when she forgot to buy a gift for Adrien on his behalf, leading her to lie and tell Adrien that Marinette's gift was actually from his father. Although wary of him becoming disappointed with her, Nathalie is willing to stand up to him for Adrien's sake, as when she voiced her displeasure with him for being too distracted by his missing wife to see his own son's misery during "Santa Claws".

In "The Collector", it is revealed that Nathalie is aware that Gabriel is Hawk Moth. In "Queen Wasp" indicates that she has deep feelings for Gabriel, being relieved when he decides to stop being Hawk Moth for his own well-being, but she is devastated when he changes his mind because he loves Emilie too much. Her loyalty is so strong that in "Catalyst", she helps with his plan for taking Ladybug's and Cat Noir’s Miraculouses by allowing him to akumatize her. Since "Mayura", Nathalie risks herself by using the damaged Peacock Miraculous to transform a villain in order to help Hawk Moth in his plans.

According to her in "Stormy Weather 2", Nathalie admits having deep admiration for Gabriel and knows that it has presumably morphed into romantic feelings. In "Reflekdoll", after their failure with Reflekta, she reminded him that they're stronger together in their following attempts, which resulted to be true. Despite her devotion, in "Ladybug", she disregarded his orders and concocted her own plan for getting the heroes' Miraculous, aware of Gabriel's desperation. But when she was told that her time as Mayura was over, Nathalie accepted that and knew he could call on her at any time.

However in "Evolution", Nathalie becomes worried when Gabriel tells her that most of the Miraculous are in his posession and that he even intends to use the Rabbit Miraculous to travel back in time and get the Ladybug and Cat Miraculouses. She instead suggests to him to give his past self a USB drive with instructions on how to fix the Peacock Miraculous to prevent Emilie and herself from getting sick from using it. But when he has the chance of doing so, he instead choses to go after Ladybug, losing the Rabbit Miraculous in the process, which makes Nathalie outraged that Gabriel chose his obsession on getting Ladybug and Cat Noir's Miraculouses over saving her and Emilie, and snaps at him, calling him crazy and not deserving of her or anyone's help and angrily hangs up on him, thus ending their alliance.

In "Passion", despite her fallout with Gabriel, she still worked in the Agreste mansion telling Adrien to not force himself to eat something he doesn't like only to please his father, while pretending to get along with the latter in front of him, with Gabriel putting his hand on her shoulder. After Adrien leaves, she quickly immobilizes Gabriel in an armlock, telling him to never do that again and that she helped him as a treasure hunter, his right-hand woman, bodyguard, friend and something more. Making it clear that was over now and she was only staying to protect Adrien from his madness as he wasn't doing this for Emilie anymore, but seeing his cataclysmed flesh he tells her he doesn't have much time either, shocking her and he asks for her help finding the Miraculouses to heal themselves so Adrien wouldn't be alone. After watching Emilie's recorded message and refusing to allow Gabriel to reshape the universe in his twisted image, Nathalie pretended to help him again by akumatizing herself again, secretly planning to use Ladybug and Cat Noir's Miraculouses herself, and when Monarch suspected this, she threatened to tell his identity and intentions to the heroes.

### Adrien Agreste/Cat Noir

Nathalie is usually serious around Adrien, not being very warm or close to him though she is his current main caretaker. Despite this, she does care for him, which she shows when she requests to Gabriel that Adrien be allowed to go to school after seeing how much he wanted to attend. In "Santa Claws", she sees how sad he is about his father not celebrating Christmas and asks Gabriel to spend time with his son. She even softly smiles at Adrien's joy at his friends being allowed into the mansion on Christmas. She showed concern for him when Gabriel took a big risk in "Style Queen".

In "Stormy Weather 2", Nathalie claims to have developed a great sense of affection for Adrien as she watched him grow up.

Nathalie is unaware that Adrien was Chat Noir. However, she despises the hero and wants to help Gabriel take his Miraculous from him, even telling Hawk Moth that she'll go to any lengths to end his reign. However, in "Startrain", she expressed hope that the hero would rescue Adrien when he and his class were blasted into space.

In an alternate future in "Chat Blanc", Nathalie had been horrified when she learned of Chat Noir's secret identity.

However, despite her falling out with Gabriel, she still cares for Adrien as seen in "Multiplication" when she smiles at him while he was asleep.

### Duusu

Nathalie uses him to transform into Mayura. While their relationship hasn't been much explored, it is clear that Duusu enjoys the chaos his owner causes (possibly for his moody personality) and cares for her, as he gets upset when Nathalie collapses after using the Peacock Miraculous in "Reflekdoll". As for Nathalie, she doesn't seem to heed Duusu's advice in "Ladybug", preferring to transform and create the ultimate sentimonster.

### Emilie Agreste

While their relationship hasn't been much explored, it is stated in "Stormy Weather 2" that Nathalie is deeply affected by Emilie's coma, becoming more saddened for her as time passes.

In "Evolution", she gives Gabriel an USB to fix the Peacock Miraculous in the past to save Emilie from her current condition. But Gabriel doesn't take the chance and Nathalie becomes angry at him for that and abandons her loyalty for him.

In "Passion", it was revealed that Emilie left Nathalie some prerecorded messages before falling in her coma, with the former entrusting Nathalie to help her husband to stop his obsession with the Miraculouses and to care for her son, stating she knows Nathalie will take care of Adrien as a mother would, which moves her to tears and makes her determined to find the Ladybug and Cat Miraculouses to heal herself to be there for Adrien.

### Marinette Dupain-Cheng/Ladybug

Nathalie has seldom encountered Marinette personally, only seeing her in person during the derby hat competition in "Mr. Pigeon" and briefly interacting with her in "Style Queen". On Adrien's birthday in "The Bubbler", she treats Marinette formally when on a speaker, but disregards her by claiming to Adrien that Marinette's gift was from Gabriel.

Nathalie is unaware that Marinette is Ladybug. However, she despises the heroine and wishes to help Gabriel take her Miraculous, even telling Hawk Moth that she'll go to any lengths to end her reign.
However, in "Startrain", she expressed hope that the heroine would rescue Adrien when he and his class were blasted into space.

In an alternate future, Nathalie was willing to go along with Gabriel's plan to force Marinette to break up with Adrien so she would be vulnerable to akumatisation, despite the obvious and utter heartbreak this caused the poor girl.

### Chloé Bourgeois/Queen Bee

Like most Parisian citizens, Nathalie is aware that Chloé is Queen Bee. Though she does express a little bit of doubt about it, she willingly helps Gabriel in his plot to bring Chloé over to his side. As Mayura, while battling her, she tried to persuade Chloé into joining her and Hawk Moth by saying that if she did, she could be Queen Bee whenever she liked, though Chloé refused that time. However, in Miracle Queen, Chloe was mad at Ladybug for the fact that she never gave her the Bee Miraculous and joined Hawk Moth, only to be defeated by Dragon Bug and Snake Noir before Master Fu announced Ladybug as the new Miraculous guardian and henceforth losing his memories.

* Nathalie is the only person in the present who knows that Gabriel Agreste is **Hawk Moth**, other than Félix Graham de Vanily.
	+ By the time Bunnyx is an adult, she is also aware of who Hawk Moth is.

* Nathalie appears to be suffering from prolonged health issues as a result of using the Peacock Miraculous.
* Without her, Gabriel never would have found both the Peacock and Butterfly Miraculouses. As such, she can be considered largely responsible for the events of the show happening in the first place, aside from Master Fu when he created the Dormant Sentimonster.
* Mayura was revealed at the Miraculous panel at New York Comic Con 2016 under the name "Le Paon" (French for "The Peacock").
	+ Earlier, at a panel at San Diego Comic Con, Thomas Astruc pointed to an image of her in the sneak peek collage image, commenting that she will be a new recurring supervillain that will be Hawk Moth's ally.

	+ There were also clues about her in the opening theme song for the season.
* She's the second Miraculous holder to use their power for evil after Gabriel Agreste.

* Catalyst also shares a resemblance with the Collector's design as they both have purplish skin, red glass over their eyes and black dress suits with stiff shoulders.
* Catalyst is so far the only akumatized villain not to be defeated by the French Miraculous superhero team and the only one they are not aware of.
* Catalyst is also the first akumatized villain to enter Hawk Moth's lair, aside from The Collector.
	+ She is also the first akumatized villain who didn't directly fight Ladybug and Cat Noir.
* In a video interview held on August 25, Jeremy Zag mentioned that the new main villain will make Hawk Moth appear like "a baby" in comparison. It is unknown if this villain is Mayura.
* She was said to appear as Hawk Moth's "boss" in season 3.
* Despite knowing the Peacock Miraculous was damaged, she still used it to the point that her health condition was dangerously close to Emilie Agreste's condition from the Miraculous.
