Invincible Season 4 Teaser Trailer Confirms March 2026 Release Date, Reveals Thragg Voice Actor, and Jokes About Mark Never Winning an Actual Fight

The Invincible Season 4 hype train has left the station, with its Burger Mart-inspired teaser trailer confirming a March 2026 release date.

Prime Video’s hugely popular animated superhero show returns to our screens with Lee Pace joining the voice cast as Thragg. Pace is perhaps best known for playing Ronan the Accuser in Marvel movies Guardians of the Galaxy and Captain Marvel, but his most recent high-profile role is galactic emperor Brother Day in Apple’s well-received sci-fi show Foundation.

Here’s the official blurb on Thragg:

One of the comic’s most enduring and imposing villains, Thragg leads the Viltrum Empire as Grand Regent. Trained from birth for this role, Thragg rules his people through strength, cruelty, and will – determined to restore Viltrum to its previous glory at any cost.

The teaser trailer, below, sees Mark and Atom Eve bantering about Invincible’s track record when it comes to fights. The running joke within the fandom is that Mark never wins an actual fight, but rather gets stomped on time and time again. Indeed, that’s where we left Season 3, with Invincible suffering big time at the hands of Conquest before Atom Eve goes Super Saiyan and rips the Viltrumite’s skin off.

Invincible Season 3 is Prime Video’s most watched animation season of all time, Amazon said, marking the biggest returning season of all time across all Prime Video’s Adult Animation Originals. Expectation for Season 4 is certainly high.

At Comic-Con this year, Invincible co-creator Robert Kirkman announced Invincible Season 4’s Dinosaurus voice actor, revealed how many seasons the show will need to complete the story of the comics, and joked Season 5 will be out in 2032.
