The much-anticipated action series Invincible is set to arrive on screens this year. Not just the star of the show, Mark Grayson, but each character and their quests and arcs have become deeply beloved. And the same can be said for the actors behind the voices, who brought these stories to life. 

As the beloved animated show based on Robert Kirkman’s comic series returns this March 18, there is much curiosity around the cast of the new season and whether any new voices will join. So, before the show arrives on screen, here is a look at the new names to join the show and the stars returning to reprise their roles.

Steven Yeun: Yeun, who lends his voice to Mark Grayson, will also be returning this season.

Sandra Oh as Debbie Grayson 

Seth Rogen as Allen the Alien 

Christian Convery as Oliver Grayson/Kid-Omni-Man

Sterling K. Brown as Angstrom Levy

Jeffrey Dean Morgan, Mark Hamill, Eric Bauza, and Peter Cullen are the other names set to return for the show’s Season 4. The newest names to join the show are Lee Pace (Grand Regent Thragg), Matthew Rhys (Dinosaurus), and Danai Gurira (Universa). 

With these actors on board, Season 4 will see the characters focus on one of the biggest wars, the Viltrumite War. The first three episodes will premiere on March 18, 2026. And the rest of the episodes will be released weekly.

While there is only a little time left for release of Season 4 of Invincible, can fans also expect another season after this?

The biggest news from Invincible last year was probably Season 5. According to Collider, Robert Kirkman and his team are already working on the next season. Now, what is interesting is that this might not be the last one. 

Kirkman has long hoped the TV adaptation would cover the full story from the comics, and at SDCC, he suggested it could take seven to nine seasons to do justice to Mark’s journey. With each season adapting 15–20 issues, there is hope for more seasons. Until then, all eyes will be on Season 4.
