Full Name: Nathalie Sancoeur

Alias: Mayura, Catalyst (akumatized form), Safari (temporary identity)

Age: 37 years

Gender: Female

Pronouns: She/Her

Nationality: French

Hometown: Paris, France

Occupation: Former treasure hunter; personal assistant, strategist, and bodyguard to Gabriel Agreste

Superhero / Villain Identity: Mayura

Miraculous: Peacock Miraculous (worn as a brooch)

Weapon: Hand fan

Kwami: Duusu

Power: Emotion / Amokization — Nathalie can create sentimonsters by channeling a person’s emotions into an amok feather. These beings are tied to an object containing the amok and remain under her control as long as it is intact.

Height: 6 feet, 5 inches

》Appearance: Nathalie has pale skin, sharp blue eyes, and straight black hair typically styled into a low, sleek bun with a distinct red streak running through it. She wears thin rectangular glasses and favors a professional wardrobe consisting of a black blazer, red turtleneck, fitted black pants, and heels. Her overall look is precise and controlled, reflecting her disciplined personality.

As her health declines from using the damaged Peacock Miraculous, her appearance becomes more fragile—her skin looks paler, she develops dark circles under her eyes, and her posture grows weaker.

In her Mayura form, her appearance becomes more striking and theatrical: her skin shifts to a light indigo tone, her hair turns deep blue, and her eyes glow pinkish-purple. Her outfit features elegant, feathered patterns inspired by a peacock, along with a decorative headpiece, giving her a regal yet ominous presence.

Personality: Nathalie is calm, intelligent, and highly disciplined. She is extremely composed and rarely lets her emotions show, maintaining a cold and professional demeanor in most situations. She is observant, strategic, and efficient, often acting as the mind behind complex plans.

Her defining trait is loyalty. Nathalie is deeply devoted to Gabriel Agreste, supporting his goals without hesitation—even when they cross moral boundaries. This loyalty is not purely professional; it is rooted in deep personal attachment and unspoken feelings.

Despite her reserved nature, Nathalie has a softer side. She cares deeply for Adrien and often acts as a quiet protector and parental figure. Beneath her stoicism lies emotional conflict, as she struggles between her conscience and her devotion.

》Friends: Gabriel Agreste (closest ally and confidant)

Adrien Agreste (protective, almost maternal bond)

》Family:

No clearly shown immediate family in early canon

Later implications suggest connections to a secretive organization tied to her past

》Romantic Relationships:

Gabriel Agreste — unspoken love and deep emotional attachment

》Trauma and Emotional Struggles: Nathalie’s greatest struggle is the conflict between her loyalty and her morality. She knowingly supports Gabriel’s dangerous actions, even as they harm others and herself.

The Peacock Miraculous she uses is damaged, and each transformation weakens her physically, eventually leaving her bedridden. Despite this, she continues to use it, prioritizing Gabriel’s mission over her own health.

She also struggles with emotional repression, rarely allowing herself to express vulnerability. Her fear of losing her place in Gabriel’s life and her inability to act on her own feelings contribute to her internal conflict.

》Past: Before working for Gabriel, Nathalie was a skilled treasure hunter specializing in rare and ancient artifacts. During this time, she worked closely with Gabriel and his wife, Émilie Agreste. Together, they searched for powerful magical objects, including the Miraculouses.

Through these experiences, Nathalie became deeply involved in Gabriel’s life and eventually his most trusted ally. She was aware of his identity as Hawk Moth from early on and chose to assist him willingly.

》Background: Nathalie Sancoeur is a complex and tragic figure defined by loyalty and sacrifice. She begins as Gabriel’s composed and efficient assistant, later taking on the role of Mayura to actively support his mission.

Over time, the physical toll of the Miraculous and Gabriel’s growing obsession begin to affect her. While she remains devoted, she gradually shows signs of questioning his actions, especially when Adrien is at risk.

Her character arc centers on quiet suffering, moral conflict, and eventual growth. Despite everything, Nathalie proves she is not heartless—she is someone who loved too deeply and sacrificed too much for it.

》Nobody knew her identity as a super villain and she knew nobody of the superheroes identity out of Hero except for Gabriel who is Hawk Moth.《
