Like the comics it's based on, "Invincible" is a show full of layered characters, intense fights, and surprising twists, all of which feature in the story of Omni-Man (voiced by J.K. Simmons).

Kid Omni-Man is not only Invincible's sidekick but also his brother. While he has the same powers as Invincilbe, Oliver Grayson had his own struggles.
