Good news, Invincible fanatics! The wait for new episodes is almost over. Prime Video confirmed at New York Comic Con 2025 that the highly anticipated fourth season of the adult-animated series will land in March 2026. And if you're already worried about what happens next, don't be – the show was actually renewed for a fifth season way back in July at San Diego Comic-Con!

We even got a peek at a new, fun Burger Mart-themed teaser trailer. It's a classic Invincible tradition where Mark (voiced by Steven Yeun) and his girlfriend Atom Eve (Gillian Jacobs) chat amidst the rubble, with Mark hilariously trying to take all the credit for their recent epic victory. It’s a nice reminder that amidst all the brutal action, this show still knows how to crack a joke and break the fourth wall!

Mark Grayson Faces His Darkest Path Yet in Season 4

Season 3 left us with some seriously big cliffhangers. Mark Grayson survived the mind-bending "Invincible War" against Angstrom Levy's multiverse army, but not without immense personal cost, including the death of Rex Splode. Then came the brutal battle with Conquest, where Mark barely managed to defeat the powerful Viltrumite, taking a more "pro-killing" stance in the process. Atom Eve, his girlfriend, showed off her incredible healing powers, essentially bringing herself back from the brink to incapacitate Conquest.

Show creator Robert Kirkman mentioned that after these events, Mark might realize he has to become more like his father, Omni-Man, just to survive the dire stakes ahead. We’re likely to see a "much darker Mark Grayson" who's "more willing to cross some lines." And apparently, this transformation is going to happen at possibly "the worst time in his life." Yikes!

Other lingering threads include Cecil Stedman secretly incarcerating Conquest (who's still alive!), the return of the formidable Battle Beast (because you can't just kill him off-screen!), and the demonic detective Damien Darkblood summoning a hellish monster. There's a lot for Mark to deal with before the main event even begins!

Meet Thragg: The Grand Regent of the Viltrum Empire

Now, let's talk about the game-changer: Thragg. He's not just another bad guy; he's the bad guy. Thragg is the Grand Regent of the Viltrum Empire, essentially the secret mastermind pulling the strings behind characters like Omni-Man, Anissa, and even Conquest. If Conquest was the second most powerful Viltrumite, Thragg is definitely the first. He's one of the few survivors of the devastating Viltrumite Civil War and is utterly devoted to rebuilding his civilization's power.

In terms of raw power, Thragg has all the abilities of Viltrumites like Mark and Nolan, but amplified to an insane degree. His strength is practically off the charts, his lifespan is vastly extended, and he possesses advanced healing, flight, and invulnerability. No other Viltrumite can hope to challenge his might in battle, which explains his absolute reign.

While he's not as openly bloodthirsty as Conquest and sometimes grants second chances to valuable soldiers, make no mistake: Thragg is the single biggest threat to life across the entire galaxy. He won't stop until the Viltrum Empire dominates everything.

Fans have been buzzing about who would voice Thragg, and Prime Video delivered big time with Lee Pace! Known for his captivating roles as Brother Day in Foundation and Ronan the Accuser in Guardians of the Galaxy, Pace brings a unique gravitas to every character he plays. Robert Kirkman himself revealed that Pace has been his ideal choice for Thragg even before the show came to be, admiring his ability to portray complex figures.

"There is a lot of big stuff in Invincible, and it's an escalating show," Kirkman said at the NYCC panel. "We're trying to make every season of the show better than the one before it, and Conquest is going to be extremely hard to top. I think we all agree. The way that we're going to top that very much involves this character Thragg, who is just a monumental addition to the show, who is going to change everything you think you know about the Invincible universe."

— Robert Kirkman, Co-creator

Pace himself offered some insight into his character:

"I feel like he's a pretty cool customer. He knows how powerful he is, and he's patient. He's got a plan. But there's a rage inside him that is violent in a way only Invincible can be. Watching the show, you understand that this a tone like nothing else. I love that we can go from Burger Mart to the most insane parts of the galaxy within seconds."

— Lee Pace, Voice of Thragg

Fans are already super excited, with many on social media praising his "pitch perfect" voice and confident demeanor that perfectly fits Thragg's calm, strategic, yet intensely violent nature. His iconic red-and-white uniform, complete with a cape and Grecian emperor skirt (as described in the comics), only adds to his intimidating presence.

The Road Ahead: What Thragg's Arrival Means for Invincible

With Thragg finally stepping into the spotlight in Season 4, the Invincible series is truly entering its "endgame" phase. This doesn't mean the show is ending soon (we've got Season 5 confirmed!), but it signifies the beginning of the true, central conflict that the entire series has been building towards. Mark made his choice by defeating Conquest – he's not preparing Earth for Viltrumite conquest, he's going to fight back.

Now, Thragg can no longer ignore this rebellious half-human, half-Viltrumite hero. Every future conflict will essentially boil down to Mark's struggle to mount an effective resistance against Thragg and the Viltrumites. This will involve not just relying on his Earth allies, but also looking to a growing resistance movement throughout the galaxy. Earth will become a crucial part of a much larger galactic effort to finally end the Viltrumite scourge.

Mark will be tested in ways he can't even imagine, far beyond anything Conquest threw at him. He faces the daunting need to grow stronger or watch everything he loves perish. Expect some truly epic battles and significant character development as Mark grapples with this monumental threat.

Even with Thragg in the picture, the world of Invincible is expanding! Prime Video has already greenlit Season 5, promising even more of Mark's journey. Plus, if you can't get enough of the universe, there's a fighting game called Invincible VS in development, and even a TTRPG (tabletop role-playing game) on the way. The future is looking bright (and bloody) for this beloved superhero saga!
