Invincible season 4: everything we know so far about the hit Prime Video show's next chapter

"When will Invincible season 4 be released on Prime Video?". If that's a question you've asked yourself since the show's third season ended, I've got news for you: we don't actually know.

There are quite a few things that we do know about Invincible's fourth season, though. I've handily rounded up the biggest news and rumors about the Amazon TV Original's next installment in this guide, too, so you can learn more about its likely cast, possible story direction, and future seasons.

Major spoilers follow for Invincible season 3 and the graphic novel series it's based on. So, bear that in mind before you proceed.

Invincible season 4 release date: what we know

Invincible was renewed for a fourth season in July 2024. Indeed, it was one of nine huge announcements that excited us most at San Diego Comic-Con 2024.

Work is well underway on it, too, with Invincible's social media team confirming (via X/Twitter) that voice work has been completed.

As for a possible launch date, Robert Kirkman, co-creator of the Invincible TV adaptation and comic book, indicated (via The Direct) that he'd like new seasons to air annually. That means season 4 could arrive sometime in 2026, which Invincible's various social channels have also alluded to.

That's a lofty goal for any animated project, though, which typically take two to three years to make. I'm all for a 2026 release window but, if it means its cast and crew don't have to rush progress on it, I'd be happy to wait until 2027 for the series' next eight-part chapter.

Is there a trailer for Invincible season 4?

No and there won't be an Invincible season 4 trailer for a while yet. Once one is released, I'll update this section.

Invincible season 4 cast: confirmed and rumored

Full spoilers follow for Invincible's third season.

There's no official word on who'll be back for Invincible season 4. Based on how season 3 ended, however, here's who I expect to see (or, rather, hear) again:

• Steven Yeun as Mark Grayson/Invincible
• J.K. Simmons as Nolan Grayson/Omni-Man
• Sandra Oh as Debbie Grayson
• Gillian Jacobs as Samantha Eve Wilkins/Atom Eve
• Walton Goggins as Cecil Stedman
• Chris Diamantopoulos as Donald Ferguson and Isotope
• Seth Rogen as Allen the Alien
• Christian Convery as Oliver Grayson/Kid-Omni-Man
• Ross Marquand as Rudy 'Rex' Connors and The Immortal
• Zachary Quinto as Robot
• Malese Jow as Kate Chas/Dupli-Kate
• Grey Griffin as Amanda, Betsy Wilkins, and Shrinking Rae
• Kevin Michael Richardson as Monster Girl
• Khary Payton as Markus Grimshaw/Black Sansom
• Jay Pharoah as Zandale Randolph/Bulletproof
• Ben Schwartz as The Shapesmith and Rus Livingston
• Andrew Rannells as William Clockwell
• Luke Macfarlane as Rick Sheridan
• Calista Flockhart as April Howsam
• Sterling K. Brown as Angstrom Levy
• Jeffrey Dean Morgan as Conquest
• Mark Hamill as Art Rosenbaum
• Eric Bauza as D.A. Sinclair
• Clancy Brown as Damien Darkblood, General Kregg, and Ka-Hor
• Peter Cullen as Thaedus
• Tatiana Maslany as Telia
• Shantel van Shanten as Anissa
• Tzi Mas as Mister Liu
• Todd Williams as Titan
• Jeffrey Donovan as Machine Head
• Simu Liu as Paul Cha/Multi-Paul
• Aaron Paul as Scott Duvall/Powerplex
• Jonathan Banks as Brit
• Michael Dorn as Battle Beast
• Cliff Curtis as Paul
• Zazie Beets as Amber
• Fred Tatasciore as Adam Wilkins
• Doug Bradley as The Technician
• Bruce Campbell as Damien Darkblood's demonic superior

That's an absolutely stacked voice cast, but there are even more characters who'll need to be voiced in season 4 and beyond. Among that number are Dinosaurus, Grand Regent Thragg, Space Racer, and Universa, who are all introduced in the next 12 to 15 issues of the comics. One of them has already been cast, too, with Thragg's voice actor already locked in per Invincible's Instagram account.

Meanwhile, Tech Jacket, who made his silent debut in Invincible season 3 episode 7 and will play a big role moving forward, will also require a voice actor. And, with Oliver continuing to grow at an accelerated rate, it's also possible Convery may be replaced by an adult voice actor.

There are plenty of opportunities, then, to add more big-name stars to the series' huge ensemble. I wonder if Bryan Cranston will finally stop saying no to Kirkman's requests to play someone...

There are a few characters – and voice actors – who, potential flashback sequences aside, won't return for season 4.

Jason Mantzoukas' time as Rex Sloan/Rex Splode is over following his character's death in season 3 episode 7, aka the one with the brutal Invincible War that was first teased in season 3 episode 1 and then all but revealed in the post-credits scene of season 3's sixth episode. Darkwing II also seemingly perished in that battle, so Cleveland Berto isn't likely to be back.

Richardson's time as The Mauler Twins is similarly over after they were killed by Oliver Grayson in season 3 episode 3. However, he'll continue to voice Monster Girl, so at least he's still part of the cast.

Invincible season 4 story speculation

Full spoilers follow for Invincible season 3 and the graphic novel series it's based on.

Invincible season 4 doesn't have an official story synopsis yet. However, you can remind yourself what happened last time via my Invincible season 3 ending explained piece.

That article doesn't reveal everything that happened after Mark Grayson defeated Conquest (with more than a little help from Atom Eve, FYI), though. If you want some clues about where things will go next, I'll provide some details after the below image.

One of the first big storylines season 4 should resolve is the sequids-centric one. The parasitic lifeforms made their animated debut in season 1 episode 4 and have been a regular thorn in Mark's side ever since.

With the alien race making their way to Earth in season 2 part 2's finale – read my Invincible season 2 part 2 ending explained article for more on that – they pose a huge threat to Earth's human population. Expect this to be the first big test for Mark and his fellow heroes post-Conquest.

That won't be the only problem Mark has to contend with. Despite being shown Conquest's corpse after Mark seemingly killed him in season 3 episode 8, the second-most powerful Viltrumite warrior is still alive. He's being kept in a secure and secret Global Defence Agency (GDA) location miles beneath the Earth's surface. The reason? Once Conquest wakes up from his coma, Cecil wants information on the Viltrum Empire and how it can be defeated. I can't see that going badly for Cecil and company...

So, yes, Conquest will return, but I won't reveal when or what awaits Mark when he does. Let's just say if Mark was mad that Cecil lied to him over D.A. Sinclair's reformation and continuing work on the ReAnimen, he's going to be apoplectic when he learns Conquest isn't dead.

Moving away from the titular superhero, Invincible season 4 will let us spend more time with everyone's favorite interracial bromance: Allen the Alien and Nolan Grayson. The pair didn't have much screen time in seasons 2 and 3, but that'll change next time around. Indeed, they'll have much more prominent roles as they attempt to track down allies and weapons to help them and the Coalition of Planets (CoP) in their upcoming fight against the Viltrum Empire.

They'll need all the help they can get, too, because season 4 is likely to end with another conflict – larger and more devastating than the Invincible War – between the CoP and Viltrumites. Again, no huge spoilers here, but you best prepare yourself for an almighty showdown.

There'll be lots of other subplots to be resolved and new ones to be introduced in season 4 as well. There's going to be more melodrama for Mark and Eve to deal with, the return of villains that they and Earth's other heroes will have to tackle, Immortal and Dupli-Kate settling down to start a family, another reboot of the Guardians of the Globe's line-up, and so much more.

As for new story beats not found in the comics, we there'll be one in Invincible season 4 centered on Damien Darkblood, the demon detective who was banished from Earth by Cecil midway through the show's first season.

That's where his story ends in the source material, but the Invincible season 3 finale confirms Darkblood will be back in some capacity next season. Nobody knows how it'll factor into the overarching narrative, but it's nevertheless pleasing to see Kirkman expand on his literary works where he can.

Chatting to Variety about what this brand-new material will entail, Kirkman teased: "Every superhero story has some chapter where they go to hell and they fight the devil. It happens in DC and Marvel comics. It’s a big deal.

"I never got around to doing anything like that in Invincible. I kept getting side-tracked and there was never a good time. So, it’s entirely possible that we may be doing something like that in the show, and that scene at the end of that episode is setting that up."

Where can I watch seasons 1 to 3 of Invincible?

The only place you can stream Invincible is on Prime Video, aka one of the world's best streaming services. Indeed, all three seasons of one of the best Prime Video shows are available to watch on the platform.

Will Invincible return for a fifth season on Prime Video?

Invincible season 5 hasn't been announced yet. It probably won't be until season 4's release date is announced, or until the latter is out in the world.

Kirkman hopes that Invincible runs for many more seasons, though. Speaking to The Direct, he said, "the goal is to adapt the entire comic", but wouldn't put a definitive number on how many seasons it'll take to do that.

Currently, each eight-episode season is adapting between 15 and 20 comic book issues. Invincible ran for 144 issues so, if the show maintains that output with each new installment, it should take seven to nine seasons to tell the full story. As an Invincible devotee, I'd be okay with another five or six seasons of it, too!
