Nathalie Sancoeur

**Nathalie Sancoeur** is Gabriel Agreste's assistant who manages his fashion work, his mansion, and takes care of his son Adrien and is the secondary antagonist of *Miraculous Ladybug* (both her civilian than her supervillain name Mayura are the secondary antagonists).

## 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.

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.[8]. 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[9]. 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[10]. 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.
