A major animated project has reached a pivotal moment following new developments from Prime Video. The announcement centers on fresh promotional material, an upcoming premiere, and growing anticipation for what comes next.
The Legend of Vox Machina spin-off Mighty Nein’s poster and footage revealed
Prime Video unveiled new promotional material for The Mighty Nein during New York Comic Con 2025. The animated spin-off expands the world of The Legend of Vox Machina.
The official announcement teased, “How many problems? NEIN. The Mighty Nein takes over NYCC tomorrow and debuts on Prime Video, November NEINteeth.” The accompanying poster shows the group of adventurers — gnomes, elves, tieflings, and humans — gathered around a glowing red apple artifact framed by magical symbols, confirming the show’s November 19, 2025 release on Prime Video.
A follow-up post stated, “All stories have to start at the beginning. The Mighty Nein trailer debuts tomorrow at NYCC,” with a one-minute teaser clip viewed more than 284,000 times. The footage premieres at the convention, marking the next phase of Critical Role’s animated universe.
Produced by Metapigeon, Titmouse, and Amazon MGM Studios, The Mighty Nein is based on Critical Role’s campaign two, set twenty years after The Legend of Vox Machina. The series follows a team of outcasts who unite after a “powerful arcane relic known as The Beacon falls into dangerous hands.” It is set in Exandria, mainly across the continent of Wildemount, where tensions rise between the Dwendalian Empire and the Kryn Dynasty.
The returning voice cast includes Laura Bailey, Marisha Ray, Taliesin Jaffe, Ashley Johnson, Liam O’Brien, Travis Willingham, and Sam Riegel. Matthew Mercer voices Essek Thelyss. Guest actors include Auliʻi Cravalho, Alan Cumming, Rahul Kohli, Anika Noni Rose, Mark Strong, and Ming-Na Wen.
Showrunner Tasha Huo said the adaptation reflects “a more mature, elevated storytelling.” Willingham confirmed they have already recorded both the first and second seasons.
