Startrain

Marinette's class is having a field trip to London, but Marinette believes she cannot attend since doing so would leave Paris vulnerable to Hawk Moth. Master Fu gives her the Horse Miraculous, which grants the power of teleportation, so she can enjoy herself and be able to return to Paris in case of an emergency. Max's mother, a train conductor who directs the Startrain, dreams of being an astronaut and has taken an exam to begin training. However, a rogue akuma gets aboard the train to London in Sabrina's big suitcase after a botched attempt to akumatize Officer Roger. When Max's mother succumbs to nerves waiting for confirmation about whether she passed, the akuma infects her and turns her into "Startrain" itself, and she drives the train into outer space. Since the akuma is outside of Hawk Moth's range of influence, Gabriel is forced to rely on the heroes to rescue Adrien. Ladybug gives Max the Horse Miraculous, turning him into the superhero "Pegasus". With his aid, the heroes teleport the train back to Earth, so Ladybug can safely purify the akuma. Afterwards, Max's mother gets the e-mail confirming she passed her exam, much to her delight.

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.
