While working as the Agreste's assistant, Nathalie also worked in studying the Grimoire on how to use the powers of the Miraculous effectively after Gabriel and Emile started using the Butterfly and Peacock Miraculouses. But thing would change forever when it was discovered the Peacock Miraculous was damaged, causing Emile to fall ill and later falling into a coma. Heartbroken, Gabriel turned to a life of isolation, while Nathalie continued to watch over Adrien.

## Personality

### As Nathalie

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 to people of greater authority. 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 its from Gabriel when in reality it was from Marinette Dupain-Cheng. Despite this, she doesn't always obey Gabriel's orders or has acted rebelliously, often in order to let Adrien have fun and out of the shadow of his father's influence or, in a dangerous step, her use of the Peacock Miraculous.

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. She cares deeply for Adrien, and is happy to know that he has made friends at school. 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.

Despite initially being extremely loyal to Gabriel, Nathalie is not above to perceive the madness forming in Gabriel's mind. With her slowly becoming more and more attached to Adrien in an attempt to make sure he is safe.

Nathalie is fully aware of the consequences of using the damaged Peacock Miraculous. However, she is unfazed about it due to her
