Invincible is an adult animated superhero show that revolves around seventeen-year-old Mark Grayson (Yeun), who’s just like every other guy his age -- except that his father is the most powerful superhero on the planet, Omni-Man (Simmons). As Mark develops powers of his own, he discovers that his father’s legacy may not be as heroic as it seems.

Those familiar with the Skybound/Image comic of the same name will be pleased to learn that Ali will voice Titan, Brown will voice Damien Darkblood, Byer will voice both Vanessa and Fiona, Donovan will voice Machine Head, Groff will voice Rick Sheridan, Hamm will voice Steve, Hounsou will voice Martian Emperor, and Miller will voice D.A. Sinclair.

The eight-episode, hour-long series hails from The Walking Dead creator Robert Kirkman, who created the comic with Cory Walker and Ryan Ottley. Kirkman is also executive producing alongside Simon Racioppa, David Alpert, Catherine Winder, while Jeff Allen serve as supervising directors. Skybound produced Invincible, which concluded its 15-year run in February 2018, making it Kirkman’s second-longest comic-book series.
