With the Cat Miraculous, when inhabited by Plagg, Adrien transforms into Cat Noir a black cat-themed superhero with the power of Destruction, tasked with protecting Paris from akumatized villains, as well as other dangers with ladybug.


Adrien is charismatic, along with being shy and a bit reserved. While he likes to have fun, he is more serious, obedient, and less lively due to his strict upbringing. If something makes him sad, he tries to downplay his feelings on it, like his relationship with his father. He thinks reasonably, and he will express annoyance and frustration when someone is being difficult or something is going wrong. Though not very openly emotional or affectionate to most people, he is friendly and encouraging, and for those he is close to, he has an easier time letting his feelings show. As Cat Noir, Adrien, having the freedom to act however he wants outside of his normal life, lets his wilder side come out, being cocky and outgoing. More optimistic and open, Cat Noir says whatever comes to his mind and makes a lot of jokes and puns, many being cat-related. In his attempts to get Ladybug's attention.
