Over the course of three seasons, fans have watched some of their favorite comic moments brought to life in animation courtesy of Prime Video’s immensely successful Invincible. While fans wait for season 4 to make its debut in 2026, Prime Video revealed that there’s even more Invincible in the works, as the streamer announced that the series has been renewed for a fifth season. That wasn’t the only great news though, as the series is also making a brand new addition to an already stellar cast.

As part of the season 5 announcement, Prime Video revealed that Matthew Rhys will be joining the cast for season 4. Rhys is no stranger to anatimion, as he’s starred in animated favorites like Gremlins: Secrets of the Mogwai and The Owl House, as well as bringing the animated version of Nite Owl to life in the recent Watchmen adaptation from DC, though he’s most well known for his role as Philip Jennings in the acclaimed series The Americans.
No release date for season 5 is mentioned in the announcement, but Prime Video does shine a light on just how big of a hit the series has been for them so far. Invincible season 3 is Prime Video’s most-watched animation season of all time, and it now holds the biggest retiring season of all time across Prime Video’s adult animation originals. Season 3 also resonated with critics, boasting Emmy Award and Critics’ Choice Award nominations and a Certified Fresh score on Rotten Tomatoes.
As for what fans can expect in season 4 (and likely season 5 as well), Robert Kirkman has teased some details, with one key reveal being that fans will finally start to see more Viltrumite threats making their way into Mark’s world. That includes a foe that will easily be the most powerful Mark has faced to this point, with Kirdkman telling Deadline, โThragg is cast and will be in Season 4,โ Kirkman then added, โSo, I wonโt reveal anything other than if youโve been watching the show since Season 1, you might be like, โHey, when is there going to be more Viltrumite stuff?โ I will say that Season 4 has more Viltrumite stuff that you might be wanting.โ
โIn Season 2, we got the cool Anissa stuff and then Nolanโs story. In Season 3, we got Conquest, and Nolanโs story, and stuff going on in space with Allen. In Season 4, it really ramps up. So, the people that are loving that aspect of the show, you will definitely get more of that,” Kirkman said.
In addition to Rhys, Invincible boasts an impressive cast that includes Steven Yeun (Invincible), Sandra Oh (Debbie Grayson), J.K. Simmons (Omni-Man), Seth Rogen (Allen the Alien), Walton Goggins (Cecil), Gillian Jacobs (Atom Eve), Jason Mantzoukas (Rex Splode), Zazie Beetz (Amber Bennett), Grey DeLisle (Monster Girl), Zachary Quinto (Robot), Chris Diamantopoulos (Donald Ferguson), Ross Marquand (Immortal), Khary Payton (Black Samson), Andrew Rannells (William Clockwell), Kevin Michael Richardson (Mauler Twins), Ben Schwartz (Shapesmith), Clancy Brown (Damien Darkblood), Jay Pharoah (Bulletproof), Mark Hamill (Art Rosebaum), and Melise Jow (Dupli-Kate).
