Oliver Grayson

Oliver Grayson is Mark Grayson's younger half-brother, born of their Viltrumite father Nolan and an alien mother from the planet Thraxa. He inherits Viltrumite physiology, granting him superhuman abilities, and eventually takes on a costumed identity operating alongside his brother.

Robert Kirkman and Ryan Ottley introduced Oliver Grayson to Image Comics readers in Invincible #7 (2006), dropping him into one of the Modern Age's most celebrated superhero universes right alongside heavy-hitters like Mark Grayson, Invincible, Allen the Alien, and Samantha Eve Wilkins. His appearances stretch across both Invincible and Savage Dragon, giving him a footprint in two of Image's signature titles. A compact but memorable presence in that corner of the Image universe, Oliver is the kind of character who rewards readers who dive deep into Kirkman's richly populated world.
