Adrien Agreste

Adrien is the deuteragonist of LadyBug. He is a student who attends the same school as Marinette. With his magical ring, inhabited by a creature known as a kwami that has the appearance of a cat, he has the power of bad luck and can transform into the superhero Chat Noir (Cat Noir in the English dubbed version), the sidekick of Ladybug.

The person who will voice Adrien in the French version hasn't been revealed (though he was shown in a photo), but in the English dub, Adrien will be voiced by Bryce Papenbrook.

Normal
Adrien has blonde hair and green eyes. He wears a white shirt with a collar and rolled-up sleeves above his elbow, and a black shirt underneath with five horizontal stripes around the chest which are colored, from top to bottom, yellow, olive green, bright green, dark green, and periwinkle. On the ring finger of his right hand, he wears the black-colored ring that uses to transform in Chat Noir. Additionally, he wears dark blue jeans and red sneakers with white lace.

Chat Noir
Chat Noir wears a black leather suit with a golden bell on his chest. He has a long belt that hangs out like a cat's tail, gloves with claws at the end, and boots. He has black cat ears and a black mask covering on his face. His eyes, including the area around his irises, are green, and his hair is messy and untamed.

Personality
Adrien is very shy and reserved.

As Chat Noir, Adrien is more confident and outgoing. In his attempts to get LadyBug's attention, he brags and boasts about himself.

Marinette Cheng/Ladybug
Adrien doesn't seem to care much about Marinette.

However, he is infatuated with Ladybug, often trying to impress her and win her affection.

Trivia

 * Fans originally called him Felix, after a famous cat character. For some time, this name appeared on the original French version of Zagtoon's official website, but has since disappeared with newer equally reliable sources calling him Adrien.
 * The name Chat Noir is literally French for Black Cat. This is due to the series' French origins. However, some sources have called Chat Noir "Black Cat" instead. It is unknown which name he will be referred to in the English language distribution.
