Featured Snippet Summary

“Nemesis” is the 26th and final episode of Miraculous: Tales of Ladybug & Cat Noir Season 6, and the 157th episode of the series overall. It closes out the season as the second half of a two-part finale alongside “Secret Protocol,” airing August 8, 2026 on Disney Channel in the US, with international dates varying by broadcaster.

Episode Overview

Season 6 has spent its back half tightening the net around Marinette and Adrien’s double lives, and “Nemesis” is where that tension is set to come to a head. As the finale, it carries the weight of resolving threads that have been building across the season — particularly the season’s central mystery around the new Butterfly Miraculous holder.

The episode is directed by Thomas Astruc and Wilfried Pain, with a writing team that includes Astruc, Sébastien Thibaudeau, Camélia Acef, and Chloé Paye.

Official Synopsis

The confirmed logline for “Nemesis” reads: as Marinette feels Alya getting closer and closer to uncovering her secrets, Ladybug comes up with a plan to flush out the new Butterfly holder. A separate broadcaster description frames the episode as Ladybug and Cat Noir facing a mysterious new enemy who is surprisingly close to them, while Marinette and Adrien have never been closer — even as secrets between them complicate things further.

Beyond that, Miraculousflix and Zagtoon have not released a full plot breakdown. Any specific scene details circulating online should be treated as speculation or leaks rather than confirmed information until officially verified.

What to Expect From the Story

Given the synopsis, a few threads seem likely to converge in this finale:

• The Alya subplot — Alya’s growing suspicion about Marinette’s identity has been a slow burn through the season, and “Nemesis” appears to be the episode where that pressure peaks.
• The Butterfly holder mystery — Season 6 introduced a new figure wielding the Butterfly Miraculous following Gabriel Agreste/Monarch’s defeat. Ladybug’s plan to “flush out” this holder suggests the finale will unmask or directly confront them.
• Marinette and Adrien’s relationship — The official copy notes the pair have “never been closer,” suggesting the finale will also move their personal relationship forward, not just the superhero plot.

These are reasonable expectations based on confirmed marketing copy, not verified plot points — treat them accordingly until the episode airs.

Characters Involved

Expect the core cast to be front and center: Marinette Dupain-Cheng/Ladybug, Adrien Agreste/Cat Noir, Alya Césaire, and the wider Miraculous team. Given the finale framing, supporting heroes who have played larger roles in Season 6 are also likely to appear, though an official character list for the episode has not been published.

Villains and Antagonists

The episode’s title, “Nemesis,” points directly at the new Butterfly Miraculous holder introduced this season as the primary antagonist. Beyond the title and the synopsis line about Ladybug’s plan to expose them, the show has not officially confirmed the villain’s identity for this episode.
