After a critically acclaimed and blood-soaked run, Amazon Prime Video’s Invincible is gearing up for an even bigger future. With Season 3 hitting our screens in February 2025 and the bombshell announcement of a March 2026 release for Season 4, fans have a lot to look forward to. The series, based on the groundbreaking comic book by Robert Kirkman, has become a cornerstone of superhero animation, and it’s not slowing down anytime soon. In fact, with a fifth season already confirmed and in production, Invincible is proving that adult-oriented superhero stories have a massive audience hungry for more.
When Are the Invincible Season 3 and 4 Release Dates?
Get ready for a double dose of superhero mayhem. Invincible Season 3 is set to premiere in February 2025, delivering eight new episodes that will continue Mark Grayson’s brutal journey through the superhero world. This marks a much shorter wait than the gap between the first two seasons, which frustrated fans with a nearly three-year hiatus and an unpopular mid-season break during Season 2.
But the even bigger news dropped at New York Comic Con 2025: Invincible Season 4 is officially slated for a March 2026 release. This confirms the creative team’s commitment to a more consistent, near-annual release schedule, a welcome change for fans eager to see the full comic storyline adapted. The announcement came alongside a Burger Mart-inspired teaser trailer that perfectly captures the show’s blend of mundane suburban life and cosmic-level violence.
The shift to annual releases represents a major commitment from Amazon Prime Video and Skybound Entertainment. It’s a recognition that Invincible has become one of the platform’s flagship shows, joining the ranks of other successful Prime Video originals. For fans who’ve been following the series since its March 2021 debut, this consistency is exactly what they’ve been asking for.
Who Is in the Invincible Season 4 Cast?
The star-studded voice cast of Invincible is only getting bigger, and Season 4 is bringing some serious Hollywood firepower to the mix. While we can expect our favorite series regulars to return, some heavy hitters are joining the fray for what promises to be the most intense season yet.
Lee Pace (Foundation, Guardians of the Galaxy) has been cast as the menacing Grand Regent Thragg, the main antagonist of the latter half of the comic series. For those familiar with the source material, Thragg represents the ultimate Viltrumite threat—more powerful, more ruthless, and more ideologically committed to the empire than even Omni-Man. His introduction signals a major escalation in the series’ stakes.
Additionally, Matthew Rhys (Perry Mason, The Americans) will be voicing Dinosaurus, a complex and morally ambiguous character from the comics who challenges Mark’s understanding of heroism and the greater good. Rhys’s casting is particularly exciting given his ability to portray nuanced, conflicted characters.
Here’s a comprehensive look at the incredible talent bringing these characters to life:
Character | Voice Actor | Notable Works |
|---|---|---|
Mark Grayson / Invincible | Steven Yeun | The Walking Dead, Nope |
Nolan Grayson / Omni-Man | J.K. Simmons | Whiplash, Spider-Man trilogy |
Debbie Grayson | Sandra Oh | Grey’s Anatomy, Killing Eve |
Samantha Eve Wilkins / Atom Eve | Gillian Jacobs | Community, Love |
Grand Regent Thragg | Lee Pace | Foundation, Guardians of the Galaxy |
Dinosaurus | Matthew Rhys | The Americans, Perry Mason |
Allen the Alien | Seth Rogen | Superbad, The Boys |
Cecil Stedman | Walton Goggins | Justified, The Shield |
Robot | Zachary Quinto | Star Trek, Heroes |
Rex Splode | Jason Mantzoukas | The Good Place, Brooklyn Nine-Nine |
Monster Girl | Kevin Michael Richardson | The Cleveland Show, Mortal Kombat |
Angstrom Levy | Sterling K. Brown | This Is Us, Black Panther |
Conquest | Jeffrey Dean Morgan | The Walking Dead, Supernatural |
Art Rosenbaum | Mark Hamill | Star Wars, Batman: The Animated Series |
Damien Darkblood | Clancy Brown | The Shawshank Redemption, SpongeBob |
The casting continues to be one of the show’s greatest strengths. The combination of established voice acting legends like Mark Hamill and Clancy Brown with dramatic actors like Sterling K. Brown and Sandra Oh creates a unique vocal landscape that elevates the material beyond typical animated fare.

What Is the Plot of Invincible Seasons 3 and 4?
Season 3 picks up right after the devastating events of the Invincible War, where Mark faced off against an army of alternate-dimension versions of himself, orchestrated by the vengeful Angstrom Levy. The battle left thousands dead, Rex Splode among the casualties, and several heroes gravely injured. But the real turning point comes when Conquest arrives.
Conquest, voiced by Jeffrey Dean Morgan in what fans are calling a perfect casting choice, is a battle-hardened Viltrumite sent to check on Mark’s progress in conquering Earth. When he discovers Mark has made no such progress, a brutal fight ensues that nearly kills both Mark and Atom Eve. The battle is so intense that Eve’s powers rebuild her body from near-death, unlocking new potential in her abilities.
The season ends with Mark making a shocking declaration: he’s done holding back. He’s ready to kill his enemies if that’s what it takes to protect Earth. This moral shift is a crucial character development that sets up major conflicts to come, particularly as Mark grapples with becoming more like his father while trying to remain a hero.
Season 4 will likely explore the fallout from this decision while introducing Thragg as the ultimate Viltrumite threat. We’ll also see the continued development of Oliver, Mark’s half-brother, who ages at an accelerated rate and is developing his own Viltrumite powers. The show has been praised for its faithful, yet fresh, take on the comic book source material, balancing fan expectations with necessary adaptations for the medium.
Other storylines to watch include the growing Sequid threat, Cecil Stedman’s morally questionable decisions (including secretly keeping Conquest imprisoned), and the mysterious activities of Battle Beast and Damien Darkblood. The series has proven adept at juggling multiple narrative threads while keeping Mark’s personal journey at the center.

The Legacy of Robert Kirkman’s Vision
The incredible world of Invincible was created by writer Robert Kirkman and artists Cory Walker and Ryan Ottley. Their comic book series, published by Image Comics under Kirkman’s Skybound Entertainment imprint, ran for 144 issues from January 2003 to February 2018. It’s a masterclass in long-form storytelling, building a rich universe filled with complex characters and genuine emotional stakes.
Kirkman, best known for creating The Walking Dead, brought a similar approach to Invincible: take a familiar genre (zombies, superheroes) and ask “what if we really explored the consequences?” The result is a series that doesn’t shy away from the brutal realities of super-powered combat while maintaining deep emotional connections to its characters.
The comic’s success spawned several spin-offs, including Guarding the Globe, Atom Eve & Rex Splode, and most recently, Battle Beast, which began publication in 2025. This expanded universe gives the animated series plenty of material to draw from for potential spin-offs of its own.
What Makes Invincible Different from Other Superhero Shows?
In a crowded superhero landscape, Invincible stands out for several reasons. First, it’s unapologetically violent. While the MCU and most superhero content keeps violence at a PG-13 level, Invincible shows the realistic consequences of super-powered beings fighting each other. Bodies don’t just get knocked around—they break, bleed, and die in graphic detail.
But the violence isn’t gratuitous. It serves the story by making every fight feel consequential. When Mark gets hurt, it matters. When characters die, they stay dead (mostly). This creates genuine tension that’s often missing from superhero stories where we know the hero will always win without lasting consequences.
Second, the show explores the moral complexity of heroism in ways that feel fresh. Mark’s journey isn’t just about learning to use his powers—it’s about figuring out what kind of hero he wants to be in a world where his father revealed that the greatest hero on Earth was actually a conquering alien. The series asks difficult questions about power, responsibility, and whether the ends justify the means.
Third, the character development is exceptional. Every major character, from Atom Eve to Cecil Stedman to Robot, has their own arc that feels meaningful. The show takes time to develop relationships and explore how trauma affects people, even super-powered ones. Mark’s relationship with his mother Debbie, dealing with the betrayal of her husband, is particularly well-handled.
The Future of Invincible: What’s Next?
The future of Invincible is bright, with a fifth season already in production. The creators have expressed their desire to adapt the entire 144-issue comic book series, which means we could be seeing new seasons for years to come. At the current pace of roughly 8 episodes per season, and with five seasons confirmed, we’re only about a third of the way through the source material.
The success of the main series also opens the door for potential spin-offs. The Atom Eve special that aired between Seasons 2 and 3 proved that audiences are hungry for more stories from this universe. Characters like the Guardians of the Globe, Allen the Alien, or even the villainous Angstrom Levy could support their own series.
For fans of animated superhero series, Invincible is a must-watch, and it’s exciting to see it join the ranks of other great superhero animation that’s pushing the boundaries of what the medium can do.
The show’s success has also had a positive impact on the comic book industry. Sales of the Invincible compendiums and trade paperbacks have skyrocketed since the show’s debut, introducing a new generation to Kirkman’s work. This demonstrates the symbiotic relationship between comics and their adaptations—each medium supporting and enhancing the other.
Critical and Audience Reception
Invincible has been a critical darling since its debut. Season 1 holds a 98% Fresh rating on Rotten Tomatoes, with critics praising its mature storytelling, stellar voice cast, and willingness to subvert superhero tropes. Season 2 maintained that momentum despite the controversial mid-season break, and Season 3 is positioned to be the series’ strongest outing yet.
Audiences have been equally enthusiastic. The show has sparked countless discussions online about its themes, character choices, and shocking moments. The “Think, Mark, Think!” meme from Season 1 became a cultural phenomenon, demonstrating the show’s reach beyond its core fanbase.
The series has also been recognized by the industry, earning multiple Emmy nominations and wins for its animation, voice acting, and writing. This recognition is particularly significant for adult animation, a category that has historically been dominated by comedies like The Simpsons and Family Guy.
Why You Should Be Watching Invincible
If you haven’t started Invincible yet, now is the perfect time. With three seasons available and two more on the way, there’s plenty of content to binge. The show offers something for everyone: action fans will love the brutal fight scenes, drama fans will appreciate the complex character relationships, and comic book fans will enjoy seeing a beloved series faithfully adapted.
The show also serves as a gateway to the comics. If you finish the available seasons and can’t wait for more, the comic series is complete and readily available in various formats, from individual issues to massive compendiums that collect dozens of issues at once.

Final Thoughts

With Seasons 3 and 4 on the horizon, the series is entering its most exciting phase yet. The introduction of Thragg, the continued development of Mark’s character, and the expansion of the Viltrumite War storyline promise to deliver the kind of epic, character-driven narrative that has made Invincible a modern classic.
Whether you’re a longtime fan of the comics or new to Mark Grayson’s world, there’s never been a better time to be an Invincible fan. The future is bright, bloody, and absolutely invincible.
