Invincible comes from the mind of Robert Kirkman, a comic book writer who has created many beloved properties that have seen a leap from the illustrated page to the small screen. It's a series about superheroes that focuses on the young Mark Grayson, the son of Nolan Grayson, a.k.a. Omni-Man, as he takes up the titular superhero name, Invincible. In the show, the masterful J.K. Simmons gives Nolan life with his voice and brilliant acting. Mark discovers he has abilities just like his dad, thanks to their alien DNA. Similar to Superman, Invincible is capable of flying at great speeds, superhuman strength, and durability. When Omni-Man reveals his nefarious intentions on Earth, it leads to a violent and emotional falling out between him and his son.
