Akuma

An akuma is a creature responsible for transforming people into supervillains. An army of them are created and led by Hawk Moth while Ladybug and Cat Noir are tasked to capture them.

Appearance
When it is turned into an akuma by Hawk Moth, it turns black with translucent purple spots. Before being turned into an akuma, it is pure white.

Creation and abilities
Hawk Moth creates an akuma by charging a normal butterfly with his dark energy. The purpose of an akuma is to possess an important object of a person, forming a link between the person and Hawk Moth. Once the deal is made, the akuma in the object releases black and purple smoke that transforms the person into a supervillain. They also can slit through incredibly small spaces, being able to get in an evelator's door crack while it was closed, which is impossible for normal butterflies.

Defeat
The akuma leaves the object it inhabits after it is destroyed. From there, Ladybug can catch it with her yo-yo in order to "de-evilize" it by removing the dark energy from it. Afterwards, with the akuma back to being a normal butterfly, she releases it.
