Nathalie Sancoeur

**Nathalie Sancoeur** is a character from *Miraculous Ladybug*.

## Appearance

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

## 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 when persons of greater authority like Audrey Bourgeois yelled at her, knowing the latter couldn't actually affect her and smiled with satisfaction after the event. Objective, sensible, and understanding, Nathalie is able to 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.

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 as beings who only do her bidding, having no remorse when it comes to killing the titular sentimonster when it was convenient for her.

## 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 notice. 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/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.
