Meanwhile, Kirkman said all of Thragg’s lines have been recorded, but stopped short of announcing the voice actor. Grand Regent Thragg is the true main villain of the Invincible saga, and the ruler of the Viltrumite Empire.
With Season 4 set for release in 2026, fans are wondering what Kirkman’s master plan is for Prime Video’s Invincible adaptation. During the panel, he said 7-9 series will be needed to tell the story from the comics.
“Roughly seven to eight to nine seasons I think would be necessary to do the complete arc from the comics of Invincible,” he said. “So we’ll see. Hopefully we get there. We get a tonne of support from Amazon Prime and couldn’t be more thrilled with how things are going. So, very excited and hopeful for it.”
As fans know, Invincible has at times seen a large gap between season releases, and during the panel he joked that Season 5 will be out in 2032, adding: “You can quote me on that.” Perhaps it’s more likely he’ll get close to completing the Invincible comic arc by then!
And finally, Kirkman addressed a complaint about the animation quality of Invincible, insisting it was improving with each season.

Outside of the Prime Video adaptation, Kirkman used his panel to reveal Battle Beast as a playable character in the upcoming Invincible VS video game. That’s a fighting game, but some fans are hoping for an open world Invincible game. Kirkman addressed this request, too, pointing to the massive budgets that would be required to make such a game a reality. Smaller scale Invincible games sound more realistic, based on Kirkman’s comments.
