Omni-Man

Omni-Man is a fictional superhero character who mainly appears in the Image Comics series Invincible. He is a "Viltrumite", an alien superhuman race from the planet Viltrum, and is the father of the eponymous protagonist also known as Mark Grayson.

Omni-Man rose to further popularity following the release of the 2021 animated TV adaptation, where he is voiced by J.K. Simmons. Fans immediately noticed his near-identical resemblance to J. Jonah Jameson, one of Simmons' most famous roles. The character also spawned many internet memes.
