Omni-Man is the Viltrumite superhero, and secret conqueror, at the centre of Invincible, the animated series based on Robert Kirkman's comic that premiered on Prime Video in 2021. Voiced by J. K. Simmons, he is known for shifting between a reassuring father figure and a terrifying authority figure, and short clips of his dialogue are widely reused in edits and reaction videos. The appeal is that contrast: a calm voice carrying an unmistakable threat, which keeps the line useful long after the scene itself.
