Omni-Man, also known as Nolan Grayson, first appeared in Robert Kirkman's Invincible comics before the animated series launched in 2021, with J.K. Simmons voicing the character. Clips of his blunt, authoritative lines spread widely during the show's first season alongside the Think, Mark memes, and short excerpts were turned into reaction sounds on TikTok and YouTube edits. This definite delivery survives because it works without context, letting creators borrow the character's authority for jokes, confirmations and exaggerated agreements in seconds.
