Right after defeating Mr. Pigeon again, Ladybug and Cat Noir are attacked by "Timetagger", a supervillain rapper who has come from the future to seize their Miraculouses and is able to change history by sending people to the past. The two are forced to retreat due to their Miraculouses timing out, and take cover at the museum to recharge. There, they encounter Alix, who reveals that her family watch has suddenly delivered a message asking them to destroy a certain statue in the museum. Cat Noir does so, revealing a future version of Alix who wields the Rabbit Miraculous as the superheroine "Bunnyx". The three heroes work together to defeat Timetagger, who is revealed to be the future Chris Lahiffe. During the fight, Gabriel learned that he'll eventually lose possession of the Butterfly Miraculous and will be succeeded by someone else as Hawk Moth.
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.
