Series Description
Mark Grayson is teenage superhero Invincible. He was a normal high school senior with a normal part-time job and otherwise normal life, except his father Nolan is the superhero Omni-Man, the most powerful superhero on the planet. At the age of 17, Mark begins to display superpowers, which come from his father being a member of the Viltrumite race, who, according to Nolan, pioneer the galaxy on a mission of benevolence and enlightenment. As Invincible, Mark begins working as a superhero, with his father acting as his mentor, and meeting other heroes. Then, superheroes around the world begin to die.
