In the Burrow, Bunnix sees the windows of time disappear one by one... The future is fading away. What's happening? At the same time, Marinette wakes up at home and discovers that someone has just made a wish in Paris thanks to the Cat Noir and Ladybug Miraculous. Quickly, she must transform into Ladybug... but she realizes that she no longer has her earrings! Together, Bunnix and Marinette, who have become Chronobug, will have to save the future by finding out who discovered the identity, when, and how this person managed to steal her Miraculous. Marinette realizes that the Butterfly Miraculous now has a new owner! All that remains is to hope for one thing: that Ladybug succeeds in defeating her opponent, otherwise it will definitely be the end of Ladybug.
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.
