==Summary==
Nathalie Sancoeur is Gabriel Agreste's assistant who manages his fashion work, his mansion, and takes care of his son Adrien.
In "Catalyst", Nathalie is akumatized by Hawk Moth into Catalyst, a power-enhancing supervillain, in order to empower Hawk Moth into Scarlet Moth and unleash Hawk Moth's ultimate plan in the Heroes Day.
In "Mayura", in order to save Hawk Moth from the French Miraculous superhero team, Nathalie uses the Peacock Miraculous. When the Peacock Miraculous is inhabited by Duusu, she becomes Mayura, a Peacock-themed supervillain.

Attack Potency: Wall level (Should be comparable to Adrien) | Large Town level (Effortlessly defeated Season 3 Queen Bee. Able to create Sentimonsters capable of cracking Jade Turtle's Shell-ter, which should be comparable to Carapace's) | Unknown (She's never seen in combat), possibly Town level (Should be comparable to other Akumatized Villains)
Speed: Superhuman (Should be significantly faster than Alya and Nino) | Hypersonic with FTL combat and reaction speed (Casually dodged all of Queen Bee’s attacks and escaped from her vision range in under a second. Dodged attacks from Feast) | Possibly Supersonic+ with Massively Hypersonic+ combat and reaction speed (Should be comparable to Season 2 akumatized villains)
Lifting Strength: Average Human | Class G (Easily pinned Queen Bee) | Unknown, possibly Class G (Should be comparable to other akumatized villains)
Striking Strength: Wall level | Large Town level (Superior to Season 3 Queen Bee) | Unknown, possibly Town level (Should be comparable to other Akumatized Villains)
Durability: Wall level (Comparable to Marinette, who survived a door-busting kick unharmed) | Large Town level (Tanked a hit from Ladybug's Yo-yo. Easily blocked attacks from Cat Noir after the latter received his own Cataclysm by Miraculer) | Unknown, possibly Town level (Should be comparable to other Akumatized Villains). Akuma reproduction makes her somewhat hard to put down
Stamina: High (Was able to repeatedly transform into Mayura despite her condition worsening over time, and in Ladybug, she turned into Mayura despite her sickness short time after being akumatized) | Superhuman (However, the overuse of her Miraculous deals great damage to her health, which may force her out of her transformation quicker than other Miraculous holders) | Superhuman
Range: Standard Melee Range | Standard Melee Range, higher with her Hand Fan; at least Kilometers, possibly Hundreds of Kilometers with Amok infection and sensing (Her Amokatization should be comparable with Hawk Moth's Akumatization) | Standard Melee Range
Standard Equipment: The Peacock Miraculous (Also known as the Miraculous of Emotions), which allows her to transform into Mayura, a Peacock-themed supervillain with the power of creating monsters out of emotions. Her Hand Fan, which contains feather capable of creating Sentimonsters out of peoples' emotions | Akumatized Tablet
Intelligence: Gifted (Full explaination here)
Weaknesses: Can only send one Amok at a time. If the Amokized object is taken away from her or the Amokized individual, the control of the Sentimonster would be passed to the person holding the object. The overuse of her Miraculous is extremely dangerous to her health, as it's damaged (Partially nullified after Season 3, as the Miraculous got fixed, meaning she won't suffer further damage) | Due to the nature of her powers, they can be used in favor of her enemies, meaning she must hide and fight indirectly. If her Akumatized object is destroyed, she will lose her powers. If her Akuma is purified after being defeated she won’t be able to duplicate.

Amokization: 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.

Catalyst can boost people's powers with her touch, turning the object the person holding red and giving the affected person a boost in their powers, such as Hawk Moth's Akumatizations became much more potent and has also gained the ability to send many Akumas at once. Catalyst can also communicate with those she empowered with a light mask
