It's official: Invincible season 4 will make its Prime Video debut in March 2026.

The highly-rated adult animated series' return was confirmed during Invincible's New York Comic-Con (NYCC) 2025 panel on October 10. And, while we don't have an exact release date announcement yet, it's pleasing to know the Amazon TV Original will be back on our screens in around five months' time.

Just like seasons 2 and 3, Invincible 4's launch window reveal was accompanied by a first teaser – and, unsurprisingly, it's set in the same Burger Mart that Mark Grayson visited alongside Allen and Cecil for the second and third season's respective teasers.

This time around, Mark – who's sporting some metal casts after, you know, the severe injuries he suffered in the Invincible season 3 finale – is accompanied by girlfriend Samantha Eve 'Atom Eve' Wilkins.

The Burger Mart they visit has seen better days – again, that's down to what happened in last season's eighth and final episode. Nonetheless, the teaser is full of humorous moments, including the pair discussing the fact that Mark rarely wins fights and Eve taking over the Chibi-inspired production duties joke that Mark was in charge of for seasons 2 and 3's teaser trailers.

One of the best Prime Video shows' fourth season's release window and teaser unveilings weren't the only things that were unveiled at NYCC 2025.

Indeed, as part of Invincible's season 4 panel, it was confirmed that Lee Pace (Foundation, Guardians of the Galaxy Vol 1) has been hired to voice Grand Regent Thragg.

For those unfamiliar with the character: Thragg is the Big Bad of Invincible's entire story. He's the leader of the Viltrum Empire and its strongest warrior to boot. Mark barely made it out alive against Conquest in Invincible season 3's final chapter, so he's going to need to increase his power levels to the nth degree if he's going to stand any chance of going toe-to-toe with Thragg.
