Robert Kirkman‘s Invincible is picking up a hell of a voice cast. The animated Amazon series, the first for Kirkman, has added an impressive amount of talent not just behind the mic but on the screen period.

Steven Yeun, who played Glenn Rhee on Kirkman’s The Walking Dead, will topline the voice cast.

The star packed casst includes J.K. Simmons, Sandra Oh, Seth Rogen (who is attached to the feature film take on Invincible), Gillian Jacobs, Andrew Rannells, Zazie Beetz, Mark Hamill, Walton Goggins, Jason Mantzoukas, Mae Whitman, Chris Diamantopoulos, Melise, Kevin Michael Richardson, Grey Griffin, and Max Burkholder.

The series will launch with either hour long episodes. It’s based on Kirkman’s comic series of the same name which recently ended its run and launched in 2003 running 144 issues. Kirkman created the series with Cory Walker and Ryan Ottley took over on art with the eighth issue.

The story is about Mark Grayson (Yeun) whose father is the most power superhero on the planet, Omni-Man (Simmons). Mark develops powers of his own and learns his father might not be as super as it seems.

The series will launch in 2020.
