Invincible Season 5 is coming to Prime Video in 2027. A post from PoppingCinema on X says series artist Ryan Ottley has confirmed the season will release in March 2027. Prime Video's own announcement has only given the 2027 window, according to ComingSoon, so the March date comes from that post alone.
Voice recording for the season is complete, according to ComicBook.com. Creator Robert Kirkman told Collider in the spring that final animation was being returned and ADR was underway. He could not confirm a date at the time, but floated January, April or May and said the goal is to return within roughly the same timeframe each year. A March premiere would fall between those guesses.
Lee Pace returns as Thragg and Matthew Rhys returns as Dinosaurus, according to Bleeding Cool. Jeffrey Dean Morgan will not reprise Conquest, and ComingSoon reports the streamer says the character is truly dead and will not be back.
Season 4 ended with the Viltrumites assimilating into human society to repopulate their species. Thragg warned Mark Grayson to leave them alone or he would destroy the planet, and Mark reluctantly agreed. Allen also received a posthumous message from Thaedus telling him to use the perfected Scourge Virus to wipe out the Viltrumites, though the virus could be lethal to humans too.
Season 5 will keep adapting Kirkman's original comics. ComicBook.com notes that Season 4 ended around issue #78, a little under halfway through the series, and that Kirkman has said the show will need about seven to nine seasons to finish the story.
