The Legend of Vox Machina season 4 trailer sets up a darker June return

TL;DR

Prime Video has released the official trailer for The Legend of Vox Machina season 4, and the animated fantasy series is leaning hard into cults, supernatural menace and a much darker reunion.

The new season starts on Prime Video on 3 June 2026, with three episodes arriving each week. It will stream in more than 240 countries and territories, so UK viewers should be part of the same rollout unless Amazon says otherwise.

For anyone coming in fresh, The Legend of Vox Machina is the adult animated adaptation of Critical Role’s first tabletop role-playing campaign. It follows a chaotic band of mercenary adventurers in the fantasy world of Exandria, trying to save people while barely keeping themselves together.

Still here? Good

Season 4 picks up one year after the Chroma Conclave, the dragon-led catastrophe that pushed the team to breaking point in season 3. This time, Vox Machina has scattered, with each member chasing some mix of love, family and purpose before a long-slumbering evil forces them back into the same fight.

That matters because the show works best when ridiculous banter and emotional damage are pulling in opposite directions. The trailer is full of the expected chaos, but the emphasis on dark enemies and death-cult imagery suggests this run is not just another victory lap after the dragons.

The core Critical Role cast remains in place, with Laura Bailey (The Last of Us Part II), Taliesin Jaffe (World of Warcraft), Ashley Johnson (The Last of Us), Liam O’Brien (Marvel’s Avengers), Matthew Mercer (Baldur’s Gate 3), Marisha Ray (Tomb Raider: The Legend of Lara Croft), Sam Riegel (Teenage Mutant Ninja Turtles) and Travis Willingham (Dispatch) all back.

The season 4 guest voices are nicely chosen too: Wayne Brady brings instant comedy recognition from Whose Line Is It Anyway?, while Kevin Michael Richardson (Lilo & Stitch), Debra Wilson (Star Wars Jedi: Survivor) and Tom Cardy add more animation, games and musical weirdness around the edges.

The Legend of Vox Machina has already been renewed for a fifth and final season, so season 4 is not being pitched as the finish line. It is, however, clearly part of the final climb.

If you are behind, the cleanest route is simple: catch up on the first three seasons on Prime Video before 3 June. If you are already current, the trailer makes the next question fairly pointed: how does a group built on found-family chaos hold together when the threat starts looking less like a brawl and more like a reckoning?
