Marinette's character was inspired by a young woman wearing a ladybug-themed T-shirt who once worked with Astruc. Marinette appears in most Miraculous media, including the main series, the mobile running game, and the comic books. As Ladybug, Marinette's signature ability is creation. As the holder of a Miraculous, Marinette is assisted by a small red creature resembling a ladybug called Tikki, who is a magical being known as a kwami.

Unknown to Marinette, Cat Noir's civilian identity is Adrien Agreste, a classmate whom she has feelings for. Ladybug and Cat Noir's goal is to protect Paris from the villain Hawk Moth and defeat him altogether. As a result, she is given a pair of earrings known as the Ladybug Miraculous, which when worn grants Marinette the ability to transform into Ladybug ( French: Coccinelle), her superheroine alias. After she passes the test of Master Fu, the keeper of the magical objects named the Miraculouses, by helping him, Marinette is chosen as a soon-to-be superheroine alongside Cat Noir. She is depicted as a French-Chinese teenage student who aspires to become a fashion designer and whose parents own a bakery.
