Invincible Season 4: Release Date, Plot, Cast and Latest News

The first teaser trailer for the fourth season of Invincible is out, bringing fans its highly anticipated release date and a taste of what to expect. Mark Grayson and the rest of the Earthlings won’t get even a moment of peace, as not only are the Viltrumites preparing for an invasion, but also the Sequids and, most surprisingly, demons from Hell.

Invincible season 3 featured the usual gruesome fights, alien invasions and inter-dimensional travels. Many fans thought the plot would be devoted mainly to the fight against the Viltrumites. As it turned out, the creators were still setting up the stage for a future war – in the third season, only one Viltrumite appeared.

Will there be a clash between Earthlings and Viltrumites in the fourth Invincible instalment? We’ve gathered all the news and rumours about the next season of the Amazon Prime Video series. When will Invincible season 4 be released? Invincible will be back on Wednesday, 18 March 2026.

The show’s fourth season was confirmed in July 2024. It came as no surprise – the Mark Grayson series is a smash hit on Prime Video, and there’s still plenty of comic book material left to adapt. What will the plot of Invincible season 4 cover? Spoilers for season 3 below.

For now, the creators haven’t announced an official plot description for season 4. However, we’ve prepared a list of seven key plot lines that we believe should appear in season 4. Angstrom Levy’s revenge, Viltrumite invasion, the search for weapons against the Viltrumites, Nolan’s redemption arc, threat from the Sequids, demons from Hell, and Mr. Liu’s revenge.

Angstrom Levy’s revenge is one of the most anticipated plot lines in season 4. After the gory fight in season 2, Mark was convinced that he’d murdered the mad scientist, who blamed him for his misfortune. However, in season 3, Angstrom returned to get revenge on Invincible.

The Viltrumite invasion is a major plot line in Invincible, but it unfolds slowly. In the season 3 finale, a cruel Viltrumite, Conquest, finally arrived to take over Earth. This resulted in a brutal clash with Mark and Oliver, leading to more carnage in the cities.

The search for weapons against the Viltrumites is another key plot line in season 4. As it turned out in season 2, the lame books Nolan wrote years earlier were memories of past adventures rather than sci-fi stories. Omni-Man smuggled into the novels information about artefacts and beings powerful enough to injure the Viltrumites.

Nolan’s redemption arc is also expected to be a major part of season 4. After the massacre on Earth, his stay on the planet Thraxa and the reunion with Mark, Omni-Man was captured by a troop of Viltrumites who imprisoned him and sentenced to death for betrayal.

The threat from the Sequids is another plot line that will be explored in season 4. In season 2, after being rescued from the Sequids and returning from Mars, astronaut Rus tried to build his life anew. However, as he was cleaning up his apartment, he was again attacked by an octopus-like creature that had apparently managed to get to Earth.

Demons from Hell will also be joining the mix in season 4. The Earth depicted in Invincible is struggling with a multitude of villains and alien races trying to colonise it, and it looks like they’ll soon be joined by demons from Hell. The season 3 finale featured Damien Darkblood, a demon detective, who investigated the murder of Guardians of the Globe in season 1 but was sent back to the underworld by Cecil.

Mr. Liu’s revenge is another plot line that will be explored in season 4. In season 3, an Asian cyborg who takes the form of a green Chinese dragon is the leader of the crime syndicate called The Order. After a clash with Titan, supported by Invincible, Liu’s body is killed, but his spirit is somehow restored during a ritual performed by his sidekick.

Invincible season 4 voice cast and characters – We expect the following cast members to reprise their roles in the fourth instalment of the show: Steven Yeun – Mark Grayson/Invincible, J.K. Simmons – Nolan Grayson/Omni-Man, Sandra Oh – Debbie Grayson, Christian Convery – Oliver, Mark’s purple half-brother, Zazie Beetz – Amber Bennett, Gillian Jacobs – Eve Wilkins/Atom Eve.
