Invincible is the teenaged son of Omni-Man, an extraterrestrial superhero of the Viltrumite race. Invincible inherited his father’s superhuman strength and ability to fly and he has sworn to protect the Earth. He has had trouble adjusting to his newfound powers and coping with the reality of his origins.

While Robert Kirkman has been the sole writer of the series, Cory Walker and Ryan Ottley have contributed the art. Cory Walker co-created the book and provided art from #1 to #7. Ryan Ottley assumed art duties with issue #8 and has been pencilling since. Kirkman has provided back-up space for a few aspiring comic creators, most notably Benito Cereno and Nate Bellegarde.

Markus Sebastian "Mark" Grayson is a teenage superhero who calls himself 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. Mark worked occasionally with a superhero team called the Teen Team (consisting of Robot, Rex Splode, Dupli-Kate, and Atom Eve), from there discovering that his physics teacher has been turning his students into human bombs. He stops his teacher with the help of the heroine, Atom Eve. He also foils a plan to make an army of robots, created by the Mauler Twins. Meanwhile, Omni-Man is kidnapped by aliens, taken to another dimension, but returns after what seems to be only a few days, but was actually eight months to him.

Young Omni-Man has not been a contender in any CBUB matches.
