With Amazon adapting Robert Kirkman’s Invincible comic book as an animated series, the show has moved to confirm quite the impressive ensemble cast.

Via The Hollywood Reporter, Invincible will star Steven Yeun, J.K. Simmons, Mark Hamill, Sandra Oh, Zazie Beetz, Walton Goggins, Grey Griffin, Andrew Rannells, Gillian Jacobs, Jason Mantzoukas, Mae Whitman, Kevin Michael Richardson, Chris Diamantopoulos, Max Burkholder and Seth Rogen.

The Walking Dead’s Yeun will be headlining the show as Mark Grayson, aka the titular Invincible. Grayson just so happens to be the most powerful superhero on the planet, while his father is a member of an alien race intent on decimating any and all worlds that they find.

The current plan is for Invincible to premiere in 2020.
