OMNI-MAN
Omni-Man (Nolan Grayson) is a character in American comic books published by Image Comics. He was 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 Oliver Grayson, 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.
Omni-Man was first referenced in Alan Moore's and Chris Sprouse's Supreme: The Story of the Year (1996-97), in which the titular Supreme, would illustrate the adventures of Omniman. Robert Kirkman introduced Omni-Man as the father of the titular character in his comic series Invincible in 2003.
In Invincible, Omni-Man arrived on Earth in the 1980s, where he eventually adopted the secret identity of a best-selling author named Nolan Grayson. He married Debbie, whose life he had saved, and they had a son together named Mark Grayson. In issue number 7, Nolan lures Earth's premiere superhero team, the Guardians of the Globe, to their hideout, where he brutally murders all the members. It was later revealed that the Immortal (the Guardians' leader) had been resurrected by the supervillain duo the Mauler Twins in an attempt to brainwash and control him. Remembering Omni-Man's betrayal, Immortal tracked down Nolan and battled him in public, outing him as the murderer and villain he truly is before being killed yet again. Nolan reveals that he was sent to Earth as a conqueror for the Viltrum Empire, a revelation that was in stark contrast to his previous claims that his presence was to advance human technology and protect the Earth from extraterrestrial dangers. In a confrontation shortly thereafter, Omni-Man beats his son Mark to within an inch of his life, yet he refuses to kill him before he leaves the planet.
In addition to having all the generic powers and abilities of a Viltrumite, Omni-Man ranks among the most powerful Viltrumites to ever exist, physically stronger than most and a master combatant with centuries of experience. He ranks among the most powerful beings in the universe. He has superhuman strength, able to easily lift immense amounts of weight, tear through virtually any matter and only continues to gradually grow stronger the more he struggles and ages. He has super speed, able to close tremendous distances in seconds and likewise react to the fastest of opponents.
