Brace yourselves, Invincible fans — the war for Earth is about to get a whole lot more intense. Prime Video has officially announced that season 4 of the hit animated superhero series will return in March 2026, and here’s the kicker: acclaimed actor Lee Pace will voice Thragg, the hulking Grand Regent of the Viltrum Empire and arguably the deadliest Viltrumite ever introduced. If you thought Omni-Man was dangerous, wait until you meet Thragg — a figure so formidable that even seasoned fans of the comics will be on the edge of their seats.
The announcement came alongside a newly released teaser trailer, giving audiences their first glimpse of what’s to come. Based on Robert Kirkman’s beloved comic series, Invincible follows Mark Grayson (voiced by Steven Yeun), a seemingly ordinary teenager whose life is turned upside down when he inherits the immense powers of his extraterrestrial father, Omni-Man (J.K. Simmons). These powers include superhuman strength, breathtaking flight capabilities, blistering speed, and near invulnerability.
But here’s where it gets controversial: Mark soon learns that his father’s species, the Viltrumites, are far from benevolent protectors. They have imperial ambitions aimed squarely at Earth, and Thragg stands at the very top of this ruthless hierarchy. In the comics, Thragg’s cunning and raw strength make him almost unbeatable — a living embodiment of conquest.
With Pace’s rich, commanding voice bringing Thragg to life, fans can expect a chilling dynamic shift in the series. Will season 4 continue the heartbreaking moral conflicts that rocked viewers in its earlier arcs? Will Thragg prove to be the ultimate test that forces Mark to confront not just his powers, but his own identity?
This casting choice could spark mixed reactions. Some will hail Pace as the perfect fit for the role, while others might wonder how his interpretation will compare to the raw brutality portrayed in the comics. And here’s a question worth debating in the comments: Will Thragg’s arrival mark the turning point where Invincible evolves from a family drama wrapped in superhero action into an epic saga of galactic warfare? Let’s hear your take.
