Mark Grayson
Mark Grayson is the son of Nolan Grayson, aka Omni-Man, one of Earth's most powerful protectors. His father belongs to a super-powered alien race known as the Viltrumites. His mother being a human, there was always a chance that he would never acquire his father's abilities.

After his civilian identity was warned that he wasn't "invincible" , he ended up using that word for his superhero identity.
