Plagg is the kwami of Destruction who is connected to the Cat Miraculous. With his power, Plagg's wearer can use the ring to transform into a black cat-themed superhero. At his best, Plagg can be described as being carefree and easygoing. At his worst, he is negligent, overindulgent, lazy, and sour. He isn't very helpful and doesn't take situations quite as seriously as he should. However, Plagg will be serious if the situation requires him to. Outside of his easygoing personality, Plagg can be cool, calm, collected, focused, and encouraging to others, like Tikki. He isn't afraid to speak his mind when something is a bad idea. Quite the picky eater, Plagg only enjoys eating cheese, especially Camembert, which Adrien will feed him not only to fuel his transformation into Cat Noir but also to bribe him when he isn't being helpful. He will also get distracted by anything that resembles Camembert.
