The much-anticipated fourth Season of Prime Video's animated superhero series is gearing up for its premiere soon. The streamer has officially confirmed a March 18, 2026, release date for the first three episodes, followed by a weekly release.
In the new chapter, Mark Grayson/Invincible will confront new adversaries in the form of Thragg, Dinosaurus, and Universa. Steven Yeun once again voices Invincible while new cast members Lee Pace, Matthew Rhys, and Danai Gurira voice Thragg, Dinosaurus, and Universa, respectively.
The show, based on the award-winning comic-book series co-created by Robert Kirkman and Cory Walker, is one of the most popular animated properties, particularly in the superhero and fantasy genres, within the streaming space.

The official logline is as follows: "Season 4 unleashes chaos as Mark Grayson/Invincible (Yeun) and the rest of the show’s heroes battle dangerous new villains that include Thragg (Pace), Dinosaurus (Rhys), and Universa (Gurira). 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. With the stakes and threats raised even higher this season, Invincible, Atom Eve (Jacobs), and the Guardians of the Globe must save the world."
Amazon MGM Studios and Bethesda Game Studios are producing the show jointly with Studio Lambert and Kilter Films.
