Prime Video has finally dropped the first teaser trailer for Invincible Season 4, giving us our first look at what’s next for Mark Grayson and confirming that the acclaimed animated series will officially return in March 2026.
Based on the comic created by Robert Kirkman, Cory Walker, and Ryan Ottley, Invincible has built a massive following since it debuted in 2021. The show’s second season was split into two halves, premiering across 2023 and 2024, while Season 3 hit Prime Video in 2025. Now, fans can look forward to even more brutal superhero action and emotional storytelling as Season 4 approaches.
Steven Yeun returns to voice Mark Grayson, with Gillian Jacobs back as Samantha Wilkins, aka Atom Eve. They’re joined by a cast that includes J.K. Simmons as Omni-Man, Sandra Oh as Debbie Grayson, Zazie Beetz as Amber Bennett, Andrew Rannells as William Clockwell, Walton Goggins as Cecil Stedman, Chris Diamantopoulos as Donald Ferguson, Eric Bauza as D.A. Sinclair, Ross Marquand as The Immortal, Ben Schwartz as The Shapeshifter, Jason Mantzoukas as Rex Sploade, and Malese Joe as Dupli-Kate, among others.
The big new addition to the cast is Lee Pace, who joins Invincible as Thragg, who is described as, “One of the comic’s most enduring and imposing villains, Thragg leads the Viltrum Empire as Grand Regent.
“Trained from birth for this role, Thragg rules his people through strength, cruelty, and will – determined to restore Viltrum to its previous glory at any cost.”
Pace, known for playing Ronan the Accuser in the MCU and Thranduil in The Hobbit films, brings serious villain energy to the table.
As for what’s ahead in Season 4, Prime Video released an official synopsis that teases big changes for Mark:
“While the world recovers from catastrophe, a changed Mark fights to protect his home and the people he loves, setting him on a collision course with a threat that could alter the fate of humanity forever.”
Fans can expect the series to dive deeper into Mark’s evolution as a hero while exploring the larger cosmic threats looming over Earth.
With its wild blend of graphic violence, heartfelt storytelling, and sharp humor, Invincible remains one of the most compelling animated superhero shows on TV.
