Omni-Man (Nolan Grayson) is a fictional character in the Image Universe, created by writer Robert Kirkman and artist Cory Walker (with Ryan Ottley) as an expansion of a character concept created by Alan Moore and Chris Sprouse. Omni-Man is the father of Invincible and a member of the alien Viltrumite race, working as a superhero on Earth. As is customary for males of his species, Omni-Man sports a large moustache. Omni-Man appears in Supreme, Invincible, Noble Causes, and Dynamo 5.

In the Invincible television series, Omni-Man is voiced by J. K. Simmons.
