‘Invincible’ Season 4 Trailer Drops With March Premiere Date

Prime Video has officially ignited the countdown for the return of its premier adult animated powerhouse, Invincible.

On Thursday, the streamer released the high-octane trailer for Season 4, confirming that the series will return to screens on March 18, 2026. The announcement, which coincides with the 23rd anniversary of the original comic book’s debut, promises the most expansive season to date as the narrative shifts toward the legendary "Viltrumite War" story arc.

The trailer offers fans a chilling first look at the series' new primary antagonist: Grand Regent Thragg. Voiced by Lee Pace (Foundation, Guardians of the Galaxy), Thragg is depicted as the ruthless and unmatched leader of the Viltrum Empire, whose arrival signals a dire shift in power for Earth’s defenders.

Joining the cast alongside Pace are Matthew Rhys as the chaotic intellectual Dinosaurus and Danai Gurira as the powerful warrior Universa, further populating a season that showrunners say will "unleash total chaos."

Central to the upcoming season is the long-awaited and emotionally charged reunion between Mark Grayson (Steven Yeun) and his father, Nolan/Omni-Man (J.K. Simmons). Following the brutal events of Season 3, the two are expected to set aside their fractured past to lead the Coalition of Planets against the impending Viltrumite invasion.

The footage teases massive intergalactic battles and the return of fan favorites like Allen the Alien (Seth Rogen), even as Mark struggles with the moral weight of his growing power.

As Invincible continues to dominate the adult animation lands caperecently marking its third season as the most-watched animated original on Prime VideoSeason 4 looks to push the limits of the superhero genre.

With higher stakes, graphic stakes, and the introduction of the comic’s most feared villains, the March premiere is poised to be a landmark event for the series.
