Invincible Season 4: Release Date, Trailer, Cast, Plot, and More

Invincible Season 4 is upon us, and with it return the adventures of Mark Grayson. Season 3 ended on a massive cliffhanger as Eve discovers her newfound powers to manipulate living matter. We also see Conquest defeated by Invincible. Now, in Invincible Season 4, the stakes have gone quite high as our heroes are now headed for a full-fledged war. So, if you are excited for the upcoming season to drop, check out the details for Invincible Season 4 release date, trailer, cast, and more below.

What Is the Release Date of Invincible Season 4?

Invincible Season 4 is set to release on March 18, 2026. Invincible Season 4 was announced back at San Diego Comic-Con 2024, and the release window was given to us by Variety through a conversation with Robert Kirkman. He stated that Invincible Season 4 will be released sometime in 2026, and now, the release date has been revealed to us via the official trailer.

Is There a Trailer for Invincible Season 4?

A while ago, a teaser for the upcoming seasons was released by Prime Video. Just like the teasers for the previous seasons, this teaser does not really show any clips from the upcoming season, but instead just shows us a conversation between Atom Eve and Mark, where Mark is complaining about how people say that he never wins a fight. One thing to note here is how Mark is wearing what looks to be gauntlets, but they could also be prosthetic robotic arms since his hands were severely damaged during the battle with Conquest.

However, now we have the full trailer of Invincible Season 4, and by the looks of it, there is a lot to unpack in the upcoming season. The trailer makes it certain that there will be a massive war where the heroes, allied with the coalition of planets, will go toe-to-toe against the Viltrumites led by Thragg. It appears that we will also get to see a subplot where Atom Eve is losing her powers. So, let’s wait and see what happens as the series releases on March 18, 2026.

What Is the Cast of Invincible Season 4?

Most of the cast appearing in Invincible Season 4 will return from the previous seasons. First off, we will see the protagonist, Mark, voiced by Steven Yeun, alongside Omni-Man, voiced by J.K. Simmons. Other than that, we’ll probably get to see Debbie, played by Sandra Oh, and Oliver, voiced by Christian Convery, appear on screen as well.

Now, we will also witness the return of Cecil, voiced by Walton Goggins, and his trusted ally Donald, played by Chris Diamantopoulos. Moreover, the previous season teased that Damian Darkblood, voiced by Clancy Brown, would return in the new season, along with the demon lord voiced by Bruce Campbell.

In the next season, it has been teased that Atom Eve, played by Gillian Jacobs, and Allen the Alien, played by Seth Rogen, will have a major part, so we can expect major arcs featuring these characters coming our way. Moreover, there will be some newcomers to our screens, like Thragg, voiced by Lee Pace, and Dinosaurus, voiced by  Matthew Rhys.

What Could Be the Plot of Invincible Season 4?

Invincible Season 4 might just turn out to be the best this show has offered us yet, and for good reason. First of all, Mark has finally let go of holding back and has made a vow to himself that he will most certainly kill anyone who tries to harm his family.

Other than that, this season has set up an interesting number of villains who are confirmed to appear in the upcoming season. First off, the threat of Conquest is still not completely over; on top of that, Damian Darkblood is plotting to summon Mark to hell, and the Sequid threat is still lingering.

Another interesting thing to note here is that the arc that follows Damian Darkblood is an original storyline you’ll not find in any of the Invincible comic books. However, the main villain will still be the Viltrumites, and considering we will get an introduction to Thragg, there is a good chance that we might witness some of the best action we have ever seen in Invincible so far.

Guessing the way the actual plot will carry out is quite hard at the moment, but looking at all these elements, it is certain that things will be quite exciting. As far as our assumption goes, Invincible Season 4 should follow the Viltrum War event in the comics, where Omni-Man and Mark face Thragg along with their other allies.
