Amazon Prime Video has unleashed the first teaser for Invincible Season 4 out of New York Comic Con — and the Viltrumite Empire just got a serious upgrade. The fan-favorite animated series will return in March 2026, with Lee Pace officially joining the voice cast as the fearsome Thragg, one of the comic’s most dangerous villains.

The news follows Invincible’s strong third season, which debuted in February 2025 and quickly secured an early Season 5 renewal that July at San Diego Comic-Con. It was also revealed that Matthew Rhys will voice an as-yet-undisclosed character in the upcoming season.

After a nearly three-year gap between the show’s first two installments — and an unpopular midseason break during Season 2 — Invincible’s third outing was widely seen as a triumphant return to form. Fans once again got their fix of ultra-violent superhero mayhem and emotionally charged comic book storytelling.

Season 3 left viewers hanging on multiple fronts for Steven Yeun’s Mark Grayson, aka Invincible. The young hero barely survived the Invincible War, a catastrophic event in which multiverse-hopping villain Angstrom Levy (voiced by Sterling K. Brown) assembled an army of alternate Invincibles to destroy Earth. While Mark ultimately saved his world, Rex Splode (Jason Mantzoukas) perished and several other heroes were critically injured. Levy, of course, escaped — teleporting to another universe to fight another day.

Just as Earth begins to heal, a new threat emerges: Conquest, a brutal Viltrumite voiced by Yeun’s former Walking Dead co-star Jeffrey Dean Morgan. His arrival leads to one of the series’ most intense battles yet, leaving Atom Eve (Gillian Jacobs) severely wounded. But when Conquest appears to land a fatal blow, Eve’s powers kick into overdrive — rebuilding her body and allowing her to strike back.

With Conquest defeated and contained by Cecil Stedman (Walton Goggins), Invincible takes a darker turn. Mark hints at adopting a more “pro-killing” approach to dealing with his enemies — and considering there’s a Sequid army forming, Battle Beast still alive, and Damien Darkblood busy summoning a hellish creature, he’ll need every bit of that resolve.

The teaser didn’t show much, but between Lee Pace’s addition as Thragg and the promise of another intergalactic bloodbath, Invincible Season 4 is shaping up to be worth the wait.
