Invincible is the superhero identity of Mark Grayson in Invincible. The son of the Viltrumite Omni-Man and the human Debbie Grayson, Mark develops powers as a teenager and tries to become a hero worthy of his father's example.

Mark Grayson as Invincible

Idealistic, stubborn, and compassionate, Mark repeatedly refuses to accept the ruthless Viltrumite belief that strength justifies conquest. His desire to protect Earth is tested by betrayal, trauma, and the damage his battles cause to people close to him.

Viltrumite power and a human moral choice

Mark has flight, superhuman strength, speed, endurance, and accelerated healing. His relationships with Atom Eve, his mother, Omni-Man, and his half-brother Oliver shape his changing understanding of family and responsibility.
