While Marinette is babysitting Manon, they're both playing with hand-crafted dolls that she made; Marinette playing as Lady Bug and Cat Noir and Manon playing as Lady WiFi, RoboCop and Evillustrator. Because Marinette always plays as the Ladybug and Cat Noir dolls, Manon laments that Marinette always wins and bursts into tears. Feeling guilty, Marinette allows Manon to borrow her Ladybug toy. However Nadja Chamack, Manon's mother, doesn't want her to have it since Manon already has too many toys and they get into a small argument that ends with the Ladybug doll getting torn. Manon however still desires to play with the Ladybug doll, so she asks Marinette for it behind her mother's back. After seeing Manon's puppy eyes, Marinette gives in and allows her to borrow the Lady WiFi doll instead. As Manon is playing with it, her mother finds out about the doll and confiscates it. Upset, Manon becomes influenced by Hawk Moth and turns into 'La Marionnettiste', a puppeteer who can control the people Marinette's dolls are based off on.
