Omni-Man

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. Omni-Man appears in Supreme, Invincible, Noble Causes, and Dynamo 5. In the Invincible television series, Omni-Man is voiced by J. K. Simmons. Publication history Omni-Man (as Omniman) was first referenced in Alan Moore's and Chris Sprouse's Supreme: The Story of the Year (August 1996–September 1997), in which the titular Supreme (in his civilian identity of Ethan Crane) would illustrate the adventures of Omniman. Robert Kirkman would officially introduce Omni-Man as the father of the titular character in his comic series Invincible (January 2003–February 2018), redesigned by Cory Walker and Ryan Ottley as a black-haired, mustachioed man compared to his Supreme design of blonde hair and a clean-shaven face.
