Omni-Man

Omni-Man is Nolan Grayson, a Viltrumite warrior who comes to Earth posing as its greatest superhero and devoted family man — husband to Debbie and father to Mark, who will eventually inherit his extraordinary strength and flight as Invincible.

Few characters arrive with the kind of weight that Omni-Man carries — a Modern Age powerhouse who made his debut in Erik Larsen's Savage Dragon #102 in 2002 before becoming a cornerstone of Image Comics' superhero universe. He's most at home in the pages of Invincible, where he shares adventures with the likes of Invincible himself, Cecil Stedman, and Ethan Crane, keeping some genuinely compelling company across a run that stretched into the 2010s. With a key issue already to his name and appearances across titles like Dynamo 5: Sins of the Father and Invincible Presents Atom Eve, Omni-Man is the kind of figure whose presence signals that something significant is happening on the page. If you're building out your Image collection and want a character who defined an era of creator-owned superhero storytelling, this is one worth tracking down.
