Nathalie Sancoeur

Nathalie Sancoeur is an antagonist in Miraculous Ladybug. Her supervillain identity is Mayura. She also appeared as the akumatized villain Catalyst.
==Canon==
Nathalie is smart, professional, and cold at times, though she begins to show more warmth in later seasons. She works for Gabriel Agreste, who she has a very close relationship with. At the beginning of Season 2, it is revealed that Gabriel is Hawkmoth, and Nathalie has been aware the entire time. She is the only one who Gabriel has trusted with his identity and plan. Nathalie is also shown to be somewhat of a parental figure to Gabriel's son, Adrien Agreste.
At the end of Season 2, Nathalie takes the Peacock Miraculous, against Gabriel's wishes, to become Mayura. Although he protests at first, he allows her to continue using it through Season 3. The broken Miraculous hurts her and makes her ill.
It was long suspected that Nathalie was in love with Gabriel. This was confirmed in the episode Stormy Weather 2. Gabriel appears to remain unaware of Nathalie's feelings, even though his own feelings for her have been called into question by Adrien.
==Fanon==
Nathalie has been treated as somewhat of a blank slate in fandom. Prior to Season 2, her appearances were very limited. Fandom depictions were wide and varied.
Even with increased appearances, much of Nathalie's life is still a mystery. Very little is known about her relationships outside the Agreste family and what she does outside of work. Many fans have taken to filling in the blanks with their own headcanons. Fanworks commonly depict Nathalie as a friend of other adult women in the show, including Nadja Chamack, Caline Bustier, and Penny Rolling.
==Notable Depictions in Fanworks==
===Common Tropes in Fanworks===
*Sickfic: With Nathalie's illness getting worse through Season 3, fanworks featuring her as sick or injured from the Miraculous became common.
*Pregnancy: For unknown reasons unrelated to canon, there are a high number of Nathalie-centric fanworks that have her become pregnant, mostly with Gabriel's child.
*Nathalie Doesn't Know: AU fanworks in which Nathalie is unaware of Gabriel's identity.
**Identity Reveal: Most of the above works lead to this eventually.
*Protective Nathalie: Nathalie acts in a protective manner towards her loved ones, particularly Adrien.
*Unrequited Love: Gabriel doesn't return her affections.
**Requited Unrequited Love: Gabriel does return her affections, but neither are aware.
*Kwami Swap: A common trope for all Miraculous holders. Kwami Swaps with Nathalie Sancoeur often involve her switching Miraculous with Gabriel.
*Sexually Explicit Fanworks: As one of the few adult characters in the show, Nathalie smut is common.
*Polyamory: A common solution in the fandom to allow Gabriel to be with Nathalie while still resurrecting Emilie, via the Sangrestes ship.
===Common Pairings===
Nathalie pairings are fairly evenly split between het and femslash.
*GabeNath: Gabriel/Nathalie. The most popular Nathalie pairing, and number 7 overall in the fandom.
*MamaNath: Nathalie/Emilie Agreste
*Sangrestes: A polyamorous ship with Gabriel, Nathalie, and Emilie.

==Example Fanworks==
===Fanfiction===
* heartless by design by darkavenue (archived version) - "Nathalie closed her eyes and pushed two fingers between her eyebrows. 'As you may have noticed, Gabriel is closing in on me viciously. If we are going to get this line manufactured before he shuts every door in our face, the designs need to be finalized in five days or less.' For a few seconds, Marinette could only blink in stunned disbelief. “That’s impossible.' 'It better not be.'" - gen, Nathalie & Marinette Dupain-Cheng, background Nathalie/Penny Rolling, posted 2016
* The Sancoeur And Barbeau Ex-Superhero Support Club by thescuttlebugg (archived version) - "'I cannot believe you got akumatized over a different Ladybug,' Nathalie says witheringly over monthly brunch at the same cafe they used to end every patrol on the roof of all those years ago. She is as perfectly put together as always, neatly pressed and polished. Theo tries, honestly, but he’s not sure he doesn’t still have warehouse grit in his jacket from last week. 'I missed you!' he says guiltily. 'You’ve been so busy lately!'" - Nathalie/Theo Barbeau, episode tag, crack treated seriously, posted 2017
* The five times Nathalie thought about adopting Adrien and the one time she actually went through with it by Buttercup_ghost (archived version) - "'Nathalie," he said, almost pleading, 'he's my son.' She looked at him, gaze cold, and replied, 'Not anymore, Gabriel.' And then were gone, the resounding clack of Nathalie's heals the only warning he got before the door slammed in his face." - Nathalie & Adrien Agreste, parental!Nathalie, adoption, posted 2017
* On the Bias by ehmazing (archived version) - "The Agrestes used to travel for business. Nathalie used to go with them." - explicit, GabeNath and Gabriel/Emilie and Nathalie/Emilie, infidelity, posted 2018
* Ten Thousand Pounds of Feathers (archived version) by dishwater-blondie (ReminiscentLullaby on AO3) - "Nathalie learns something earth-shattering about Adrien that could change everything she and Hawkmoth have been working towards. But then again, it might change nothing at all." - GabeNath, posted 2019
* A Change of Luck by fleurjaune (archived version) - "Shadow Moth is thrown to be confronted by a woman in Chat Noir's place. It shouldn't really make a difference in his quest but he finds himself strangely drawn to her. Meanwhile Nathalie Sancoeur is having a well deserved breakdown." - GabeNath, identity porn, enemies to lovers, kwami swap, posted 2022
