Season 2 of Invincible will soon get underway and it sounds like the violent animated series will be even more "bonkers" when it returns. From The Walking Dead creator Robert Kirkman, Invincible is based on the comic book series of the same name by Kirkman, Cory Walker, and Ryan Ottley. Steven Yeun, who previously worked with Kirkman on The Walking Dead as the fan favorite Glenn Rhee, leads the voice cast of Invincible as the titular rookie superhero.

In a new interview with Collider, Yeun spoke about the upcoming second season. While this brings the revelation that they haven't actually started yet, it sounds like production will begin in the near future. Yeun also points to the original Invincible comics and promises that season 2 will be pretty exciting based on the compelling source material they all have to draw from.

"We haven’t started. I know we’re starting at some point soon. I’ve talked to Robert [Kirkman], here and there. He’s super excited about it. He thinks Season 2 is gonna be even better than Season 1, which I have no doubt about. If you go to his source material, Invincible is an incredible comic, and just thinking about how much story hasn’t been told from that run, it’s gonna be bonkers. I’m really excited about it."

Invincible Was a Smash Hit for Prime Video

When Invincible debuted on Prime Video last year, it was a big hit with viewers. The positive response convinced Amazon to go ahead and order not just one, but two more seasons of the show. For his part, Yeun did not anticipate that the series would strike quite as well as it did. This is something the Minari actor attributes to a growing interest in adult animation, and as a lifelong fan of the genre, he couldn't be more thrilled.

"I’ll be honest, I did not expect this level of response. People really enjoyed the show. That’s not to say that I thought the show wouldn’t be enjoyed. I just didn’t know how many people were coming to it like that. To me, I think it speaks to America’s appetite now for adult animation, which is really cool. I grew up on it. I think all of us, of our generation and below, grew up on it. Largely, our programming was dictated by the generations before us, that didn’t necessarily love animation that way. We’re in a weird, cool time where I’m seeing so many kids watch anime and so many people watch adult animation."

Invincible follows Mark Grayson (Yeun), a teenager whose entire life is forever changed when he becomes a budding superhero under the guidance of his father, Nolan (J. K. Simmons), aka Omni-Man, the most powerful superhero on the planet. Major problems ensue when Mark discovers his father's dark secrets and isn't quite so willing to follow in his footsteps any longer.

There's no word yet on when the second season of Invincible will arrive, and it could be a little while yet if production hasn't gotten fully underway. For now, you can watch every episode of the first season streaming on Prime Video.
