Invincible Star Steven Yeun Teases a 'Bonkers' Second Season

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.
