It's almost as though critters collectively rolled a natural twenty. The next animated adaptation of a Critical Role campaign, The Mighty Nein season 1, will be arriving for streaming on Prime Video before you know it. Set twenty years after the events of The Legend of Vox Machina, The Mighty Nein is based on the second Critical Role campaign. So when can you expect the release date for The Mighty Nein season 1 to arrive?

The Mighty Nein season 1 release date is November 19 on Prime Video. It has been about a year since The Legend of Vox Machina season 3 concluded in October 2024. It isn't currently clear how many episodes will comprise The Mighty Nein season 1, nor whether the show will be released all at once or on a weekly basis. It isn't the only scintillating TV release date coming your way this fall, either.

In The Mighty Nein season 1, viewers will enjoy the exploits of the titular group of seven adventurers. In addition to the high stakes storyline, the series will feature the endearing interactions among the seven characters. And the cast features some impressive heavy hitters. These include Critical Role cast members and founders Laura Bailey, Taliesin Jaffe, Ashley Johnson, Liam O’Brien, Matthew Mercer, Marisha Ray, Sam Riegel and Travis Willingham. The Mighty Nein season 1 will also feature some impressive guest starrings, including Auliʻi Cravalho, Alan Cumming, Jonathan Frakes, Tim McGraw, Anika Noni Rose, Mark Strong and Ming-Na Wen.

The Mighty Nein season 1 will debut on Prime Video on November 19.
