Invincible Season 4 Images Highlight Villains as Thragg Prepares for His Grand Debut
Prime Video has published a batch of first-look images from Invincible Season 4, showing off returning heroes – and a sneak peek at some new villains.
Six images from the hit animated series swooped into the internet today, highlighting the always bloody Mark Grayson ahead of his return to TV screens this March. Everyone from Omni-Man and Allen the Alien to Shapesmith shows up for the new pictures, but it’s the reveal photo for Lee Pace’s (Foundation) Grand Regent Thragg that really steals the show. You can see all six Invincible Season 4 images below.
Invincible comics readers know Thragg as not only the killer ruler of the Viltrum Empire but perhaps the greatest threat Mark will ever meet. He’s as menacing as ever in the Season 4 first look, gliding through space as shadow obscures the details of his face and clothes.
Thragg is certainly the biggest name to join the Invincible animated show adaptation in its 2026 season, but he’s not the only character making an entrance. Also joining the star-studded cast – which includes Steven Yeun as Mark, J.K. Simmons as Omni-Man, Walton Goggins as Cecil, and Gillian Jacobs as Atom Eve – is Danai Gurira (The Walking Dead, Black Panther), who plays Universa. Non-comics readers can spot her taking a mean punch thrown by Atom Eve in the new set of images. We also get to see Mark face off against Dinosaurus.
The Invincible Season 4 gallery is a solid update after the long wait since an October teaser trailer debuted first footage from the next batch of episodes. Despite premiering in just a few months, Amazon and Skybound Entertainment still have yet to announce a specific release date outside of the previously promised March 2026 window.
Invincible Season 4 could start streaming in as soon as a month and a half. While we wait, you can read about why we believe Thragg’s introduction signals the beginning of the end of Mark’s story.
