[Image Credit: Titmouse] Many Critical Role fans want to know the Mighty Nein release date and runtimes for the first season of the animated series. While the show has been described as a spinoff of The Legend of Vox Machina on Amazon Prime, it’s more of a full-fledged animated version for Critical Role’s second campaign. As Critters will know, the cast’s first live-streamed campaign started in the middle of their home game, while the second effectively started fresh with new characters, meaning that the upcoming adaptation is expected to have more room for character development. Here’s when the Mighty Nein Season 1 will come out and how long each episode is expected to be.

When does the Mighty Nein show come out?

The release date for the Mighty Nein animated series is November 19, 2025 on Amazon Prime, and every episode is expected to be roughly 45-minutes long.

By comparison, the episodes for The Legend of Vox Machina are generally half as long at 25 minutes throughout its three seasons (and upcoming forth and fifth seasons). That said, the number of episodes in that series is about 12 per season. Meanwhile, as noted by the Writers Guild of America West, the number of episodes for the first season for Mighty Nein is eight (at the time of writing). This still means the Mighty Nein Season 1 is expected to be longer than a regular season of its Vox Machina counterpart.

As cast member Sam Riegel revealed in an interview with Entertainment Weekly, the Mighty Nein animated show and its longer runtime will give the cast “an opportunity to kick things up a notch in terms of character building, world building, and storytelling techniques.”

Unlike the characters in The Legend of Vox Machina adaptation, cast member Travis Willingham shared that the Mighty Nein characters will start off as pairs before they slowly come together as a group. The first season of the show will also insert cutscenes of the dark elf wizard, Essek Thelyss, doing not-so-great things to provide a different perspective of who he was in the Kryn Dynasty before meeting with the main heroes.
