Who Is Omni Man?
Omni Man, also known as Nolan Grayson, is one of the most powerful characters in Invincible. At first, he seems like Earth’s greatest hero—strong, noble, and protective. But later, we learn the terrifying truth: he’s not who he claims to be.
As a Viltrumite (a super-strong alien race), Omni Man was sent to Earth with a secret mission. He pretended to be a hero, married a human woman, and even raised a son (Mark, who becomes Invincible). But his real goal was much darker.
Omni Man Powers – Why Is He So Strong?
Omni Man is nearly unstoppable because of his Viltrumite abilities:
✔ Super Strength – Can punch through mountains and lift massive objects.
✔ Super Speed – Flies faster than any human jet.
✔ Invincible Body – Bullets, bombs, and even lasers can’t hurt him.
✔ Long Life – Viltrumites live for thousands of years.
✔ Fighting Skills – Trained in advanced combat techniques.
Because of these powers, Omni Man was Earth’s strongest protector… until he became its biggest threat.
