Mark Grayson is coming back to screens very soon, and Prime Video has finally locked down the exact dates for every single episode. The wait is almost over for the animated superhero hit, with the new season arriving next month.
The Invincible Season 4 release schedule is now official. The streaming service confirmed the complete episode breakdown through a new poster and multiple announcements over the past few days. Unlike some shows that drop everything at once, this season will mix a big premiere with weekly episodes. This gives fans time to digest the action and talk about each chapter as the Viltrumite War heats up.
The show, based on Robert Kirkman’s famous comic books, has become one of the biggest adult animated series in the world. Season 3 smashed records as the most-watched animation season ever on Prime Video. It also scored a perfect 100% on Rotten Tomatoes. Now, Season 4 aims to go even bigger with new villains, massive space battles, and emotional family drama.
Here is everything you need to know about when the episodes land, what time they stream, and what storylines are coming.
The Complete Invincible Season 4 Episode Release Dates
Prime Video confirmed the full weekly breakdown for Invincible Season 4 on February 17, 2026 . The season will consist of eight episodes total. The strategy gives viewers a lot of content right at the start, then builds suspense week by week until the finale.
The episodes will release on Wednesdays. Based on previous seasons, the expected time for new episodes is 12 a.m. Pacific Time (PT) . That translates to 3 a.m. Eastern Time (ET) for viewers on the US East Coast.
Here is the exact Invincible Season 4 release schedule:
- March 18, 2026: Episodes 1, 2, and 3 (Three-Episode Premiere)
- March 25, 2026: Episode 4
- April 1, 2026: Episode 5
- April 8, 2026: Episode 6
- April 15, 2026: Episode 7
- April 22, 2026: Episode 8 (Season Finale)
This means the entire season will run for just over five weeks. Fans who prefer to binge can wait until April 22 to watch everything, but those who follow weekly will get to join the online discussions and theories as they happen .
Where to Watch Invincible Season 4 Around the World
The new season will stream exclusively on Prime Video in every region where the service operates. Amazon MGM Studios confirmed that the show will be available in more than 240 countries and territories starting March 18 .
For viewers in India, the episodes will likely drop around 12:30 p.m. IST on Wednesdays, following the global release window. In the UK, that usually means a 8 a.m. GMT release. Australian fans can expect episodes in the early evening around 6 p.m. AWST / 7 p.m. AEST .
If you have an active Amazon Prime membership, you already have access. All previous seasons (1, 2, and 3) are also available on the platform right now for anyone who needs a refresher before the big return.
What Happens in Season 4? The Viltrumite War Arc
The story picks up right after the devastating Season 3 finale. Mark Grayson barely survived his fight with Conquest, the brutal Viltrumite warrior voiced by Jeffrey Dean Morgan. The world is still recovering from the massive destruction caused during that battle .
The official logline for Season 4 reads: “While the world recovers from catastrophe, a changed Mark fights to protect his home and the people he loves, setting him on a collision course with a threat that could alter the fate of humanity forever” .
This season dives into the famous Viltrumite War arc from the comics. This is one of the most loved storylines in the entire Invincible universe. It involves a full-scale intergalactic war against the Viltrumite Empire.
Thragg enters the scene as the main villain. Voiced by Lee Pace, Thragg is the Grand Regent of the Viltrumite Empire. Unlike other Viltrumites, he was bred from birth to rule. He is cruel, powerful, and determined to restore his empire’s glory at any cost. Pace described the character as having “a lot of depth and a lot of different extremes” in a recent interview .
The season also introduces two major new threats:
- Dinosaurus (voiced by Matthew Rhys): A complex villain who does terrible things but believes he is saving the world.
- Universa (voiced by Danai Gurira): A powerful alien with a tragic backstory who becomes a significant challenge for Mark.
Omni-Man (J.K. Simmons) returns to Earth alongside Allen the Alien (Seth Rogen). The trailer shows them asking Mark to join the fight against the Viltrumites, setting up a tense family reunion .
The Voice Cast: Who Is Back and Who Is New
Invincible Season 4 brings back almost the entire main cast. Steven Yeun leads again as Mark Grayson/Invincible. Sandra Oh returns as his mother Debbie, dealing with the fallout of her son’s violent life. J.K. Simmons is back as the conflicted Omni-Man .
The full returning cast includes:
- Gillian Jacobs as Atom Eve
- Walton Goggins as Cecil Stedman
- Jason Mantzoukas as Rex Splode
- Zachary Quinto as Robot
- Ross Marquand as Immortal
- Mark Hamill as Art Rosenbaum
- Clancy Brown as Damien Darkblood
- Seth Rogen as Allen the Alien
Lee Pace (Thragg), Danai Gurira (Universa), and Matthew Rhys (Dinosaurus) headline the new additions. This star-studded lineup promises to deliver the same high-quality voice work that the series is known for .

Why the Release Strategy Makes Sense
Releasing three episodes at once is a smart move. It rewards fans who have waited patiently since Season 3 ended. It also hooks new viewers who might be trying the show for the first time. Getting three episodes immediately allows people to really sink into the story before the weekly wait begins .
The weekly format after that helps build buzz. Each episode can be discussed, memed, and analyzed before the next one arrives. For a show like Invincible, which is famous for its shocking twists and brutal fight scenes, this keeps the show in the conversation for over a month. It worked perfectly for Season 3, so Prime Video is sticking with the same plan .
The final episode airs on April 22, 2026, exactly five weeks after the premiere.
