The voice cast for Amazon's animated adaptation of Robert Kirkman and Cory Walker's Invincible has been confirmed along with several surprising additions.

Previous reports had listed Yeun among the voice cast along with rumors that Khary Payton, Zachary Quinto and Clancy Brown would be included but the latter actors are not among the official announced voice cast.

Created by Kirkman and Walker in 2003, Invincible tells the story of high schooler Mark Grayson whose father happens to be the world's greatest superhero. As Mark begins to develop superpowers of his own, he learns his father may not be entirely what he appears. Artist Ryan Ottley replaced Walker starting with the series' eighth issue which ran for a total of 144 issues before concluding last year.
