Lila dupes Adrien into spending time with her on the pretext of helping her with homework. When they head to the Agreste mansion, Nathalie confronts them, and Lila claims that she is helping Adrien with homework. After they are done, Lila takes a picture of herself kissing Adrien on the cheek and sends it to all of Adrien's classmates. As she is leaving, Gabriel catches her and berates Nathalie and the Gorilla for allowing her access to Adrien. When Kagami receives the picture, she flies into a jealous rage, allowing Hawk Moth to akumatize her into "Oni-Chan", a villain who follows Lila with a horn on her forehead relentlessly by swapping locations with those who receive her picture message of a horn on their cell phones. During the battle, Lila quietly attempts to offer Oni-Chan help in defeating Ladybug and Cat Noir, impressing Hawk Moth. After defeating Oni-Chan, Adrien warns Lila that he will not tolerate her hurting his loved ones. Gabriel invites Lila to the mansion, and the two strike up a friendship.
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.
