Robert Kirkman is branching out of the Walking Dead universe he created and trying his hand at something totally new — an animated series!

Kirkman's Invincible is coming to Amazon Prime Video for eight hour-long episodes, and an all-star ensemble attached to voice the characters. The show, based on the popular comic book series of the same name, is co-created with Cory Walker and artist Ryan Ottley, and will premiere globally on the service in over 200 countries and territories in 2020.

There are plenty of TV adaptations in the works, from family dramas to psychological thrillers to supernatural adventures.

Invincible tells the story of average 17-year-old Mark Grayson (The Walking Dead's Steven Yeun), who is dealing with the fact that his father (Counterpart star JK Simmons) is the most powerful superhero on the planet. However, Mark slowly begins to develop his own powers, leading him to realize that his father's legacy as Omni-Man might not be as heroic as it seems.

Other notable voices to look forward to in the series, based on Kirkman's second-longest comic-book series, are Mark Hamill (Star Wars, Knightfall) Sandra Oh (Killing Eve), Seth Rogen (Preacher), Gillian Jacobs (Love), Andrew Rannells (Girls, Black Monday), and Zazie Beetz (Atlanta).
