Nolan Grayson (Omni-Man) is unquestionably the strongest being on our planet; he is also our most spirited protector, having saved the planet from untold calamity. His son Mark, wants nothing more than to follow in his footsteps. But there's something sinister afoot and Omni-man may not be what he appears. Which may prove even too much for the Guardians of the Globe.

In Season 2, still reeling from Nolan's betrayal, Mark struggles to rebuild his life as he faces a host of new threats, all while battling his greatest fear - that he might become his father without even knowing it.
