Chrysalis

"I am Chrysalis, and you are going to give me the miraculous. Before I take them by force, Polka Dots. You can't win."  -Chrysalis, "KITSUNE ORIGINS!" 

With the Butterfly Miraculous, when inhabited by Nooroo, an unknown character transforms into Chrysalis, who is the main antagonist of Miraculous: Tales of Kitsune and Mini. She wants to destroy Ladybug and take her miraculous. To achieve her goal, she creates and controls the akumas, who can transform normal people with negative emotions into supervillains.

Physical Appearance
Chrysalis is a woman of average height.

Civilian Attire
Unknown.

As Chrysalis
Chrysalis wears a dark purple dress suit with a black butterfly-shaped lapel, the Butterfly Miraculous brooch on the center of the collar. She wears a silver visor over her face. She also has a dark indigo cane as her tool. Whenever she is controlling someone with an akuma, a bright purple butterfly-shaped outline appears on her mask where her eyes would be.

As Chrysalis
Chrysalis has enhanced skills such as speed, agility, strength and near-invulnerability. She is a capable sword fighter, being able to take on Ladybug in combat. Her prowess is enough to overpower combatants most combatants.

Even without being transformed, Chrysalis' Miraculous allows her to feel emotions, whether positive or negative, like an empath, so she can precisely pinpoint the person's name and the reason why they have negative emotions.

Chrysalis' main superpower is Akumatization, charging butterflies with dark energy which transforms them into akumas and then sending them out to possess an object of a vulnerable person. She can also keep butterflies in her cane if he needs to use an akuma in another location other than her lair. If her targets agree to serve her, she transforms them into supervillains by corrupting their personalities and granting them a wide variety of superpowers or special abilities. She can also telepathically communicate with her akumatized victims and allies. A pink butterfly-shaped outline appears in front of her and the villains' faces when she does so. However, she is only able to create one villain at a time over the course of an indeterminate amount of time, she needs to convince her victims to accept the powers that she grants, and the akumatized that she creates do still have a will of their own and can either disobey her or carry out her orders incompetently. Still, if a supervillain doesn't go and retrieve the Miraculous like they were asked to, Chrysalis can control their bodies for a brief amount of time in order to inflict pain onto them until they agree to do it as quickly as possible. She is also capable of purifying an akuma herself.

When an akuma isn't purified by Ladybug, it will multiply and turn other people into frozen copies of the original akumatized villain. Hawk Moth can recall and trap the original akuma in the top of his cane in order to release it again when the victim gets sad or angry once more. This turns the victim into the same akumatized villain, but it also unfreezes the copies of them, which the original villain can command and control. However, once the original akuma is de-evilized, its copies vanish, reverting the duplicates of the villain back to normal.

As Ruby Chrysalis
Ruby Chrysalis has the same abilities as Chrysalis, but she is stronger as she can create as many akumatized villains as she desires. This is caused by her cane getting affected by an unknown source. She can use her cane to summon more ruby akumas to make the heroes feel intimidated and outnumbered. Instead of creating normal akumas, she creates ruby akumas, which are bright red, just like the akumatized.

Unlike with normal akumatized villains, Ruby Chrysalis can akumatize her victims without having to ask for their permission and the created villains are bound to obey her, showing that the will that they still had in a normal akumatization is now diminished. This will not work on people not exhibiting negative emotions.

As Sapphire Chrysalis
Sapphire Chrysalis has the same abilities as Chrysalis, but once she akumatizes someone she is able to make the akuma multiply right away and turn other people into frozen copies of the original villain. This is caused by her cane getting affected by an unknown source. Instead of creating normal akumas, she creates sapphire akumas, which are ocean blue, just like the akumatized.

Unlike Ruby Chrysalis, she will need the original victim's permission before she can akumatize more victims.

Trivia

 * Power removal
 * Akumas and Akumatized villains can retain their powers even when the Miraculous holder isn't transformed.

 * The Butterfly Miraculous is the first known known Miraculous that is being used for evil. The second is the Peacock Miraculous. The third is the horse miraculous.
 * If used for good, the Butterfly Miraculous can Akumatize people into superheroes instead of supervillains. It can also give people hope to fight when the world is in danger.
 * The power to cause pain to an Akumatized person or remove their powers is supposed to be a safeguard to prevent the person from using their powers wrongly or evilly.
