Ladybug

Lila plants the answers to a test in Marinette's backpack, pretends to have been shoved down a flight of stairs, and claims she stole a necklace from her in order to turn Marinette's friends against her. Principal Damocles falls for her lies and expels Marinette from school. Hawk Moth senses the shock and despair of everyone who trusted her and turns Nathalie back into Catalyst, so he can assume his Scarlet Moth form and akumatize the entire school. Marinette nearly surrenders the Ladybug Miraculous under Scarlet Moth's orders, but Catalyst succumbs to exhaustion caused by the Peacock Miraculous, distracting Scarlet Moth and cancelling the procedure. Alya sets out to prove Marinette's innocence as Marinette is forced to work with her father in the bakery, while Gabriel forbids Nathalie from taking anymore action to protect her health. Nathalie goes behind Gabriel's back, forges a sentimonster in Ladybug's image, and attempts to trick Cat Noir, so she can get his Miraculous, but the real Ladybug shows up just in time. Together, she and Cat Noir resolve the false Ladybug on top of the Arc de Triomphe, but Hawk Moth intervenes and escapes with Mayura before they can unmask her. Afterwards, Adrien threatens Lila into proving Marinette's innocence, and Marinette is allowed to go back to school. But Lila still holds out on having revenge on Marinette in the future.

Miraculous Season 6 Finale Explained: How Nemesis Ends a New Era for Ladybug and Chat Noir and Sets Up Season 7

The wait is over and the dust has settled over Paris. With "Nemesis," the 26th and final episode of Season 6, "Miraculous, les aventures de Ladybug et Chat Noir" has closed one of its boldest chapters to date. Season 6 premiered in France on TFOU in March 2025 and finished its French run on October 11, 2026. Across those 26 episodes, Thomas Astruc's superhero phenomenon did something few long-running animated series attempt: it changed the status quo for good. If you've just finished the finale and are still processing it, this debrief is for you.

A new cycle that took real risks

To understand why "Nemesis" lands so well, you have to remember where this season started. Season 5 ended the Agreste family arc, the storyline built around Gabriel Agreste, voiced with chilling restraint by Antoine Tomé as Hawk Moth and later Shadow Moth. Season 6 is the first season of a brand-new arc. With a new holder of the Butterfly Miraculous turning Parisians into akumatized villains, the writers had the freedom to rethink the show's formula. The premiere, "Climatiqueen," made that clear immediately, and the season kept introducing threats that felt different from the old villain-of-the-week pattern, including a wonderfully imaginative antagonist in the early episodes.
