Every Kid Omni-Man Has in ‘Invincible’, From Earth to Thraxa

Omni-Man, who once viewed parenthood as a mere whim, has developed a surprisingly intricate legacy as a father. Nolan Grayson, the Viltrumite warrior concealing his identity as a superhero on Earth, is officially the father of two sons in both the comic series and the Amazon Prime Video adaptation of ‘Invincible’. Each son is born under vastly different circumstances, which significantly shape the narrative.

Nolan Grayson is the father of Mark Grayson, also known as Invincible, and Oliver Grayson. Mark, a typical high school senior, discovers his superpowers at 17, stemming from his father’s Viltrumite lineage. This pivotal moment sets the entire ‘Invincible’ saga in motion, as Mark steps into the role of the hero his father only pretended to be.

Nolan Grayson is not only the father of Mark and Oliver but also the husband of Deborah Grayson and the paternal grandfather of Terra Grayson and Markus Murphy. The relationship between Nolan and Mark serves as the emotional core of the series, marked by a profound betrayal that gradually evolves into a semblance of reconciliation. Mark’s mother, Debbie, plays a crucial role in this dynamic, and the series emphasizes the damage Nolan’s dual existence inflicted on the family he established on Earth.

Oliver’s story takes a more unusual turn. After departing Earth, Nolan discovered a new planet, Thraxa, where he ruled and took a native wife named Andressa, resulting in the birth of Oliver. This second son, who adopts the codename “Kid Omni-Man,” joins Invincible on Earth. Oliver symbolizes Nolan’s ability to start anew, ultimately becoming a compelling hero in his own right.

Oliver Grayson II, introduced in Season 2 and beyond, is a significant character in ‘Invincible’. As a Viltrumite–Thraxan hybrid, he is the superhero known as Kid Omni-Man, the son of Nolan Grayson and Andressa, the legally adopted son of Debbie Grayson, and the younger half-brother of Mark Grayson. The fact that Debbie adopts Oliver, the child her husband had with an alien during his exile, stands out as one of the show’s more remarkable character developments.

Oliver first appeared as a baby in Season 2, and after the Viltrumites took Nolan, he was cared for by Mark and Debbie Grayson on Earth. In the Season 3 trailer, Oliver is seen sporting a new Omni-Man-inspired costume as he fights alongside his brother Mark. The evolving relationship between the two brothers promises to be a rich narrative thread in the upcoming episodes, particularly as they navigate their differing worldviews. A notable conflict arises as Kid Omni-Man challenges Mark Grayson’s no-kill rule, a sensitive topic given the events involving Angstrom Levy.

Both sons embody different aspects of who Nolan Grayson was during their conception. Mark was born when Nolan was a Viltrumite sleeper agent, masquerading as a devoted husband and Earth’s greatest hero. In contrast, Oliver was born after Nolan’s failure and exile, during a brief period when he ruled an alien world and attempted to start anew. Oliver’s unique Viltrumite-Thraxan hybrid status, along with his distinct purple skin, sets him apart from other Viltrumites, aligning with his comic book portrayal.

The series does not shy away from exploring the complexities of Nolan’s fatherhood. His chilling dismissal of Mark, suggesting he could easily father another child, lingers throughout the series, highlighting how Viltrumite logic can diminish the emotional significance of human relationships. However, both sons ultimately resist that coldness, each in their unique way, making the family of Omni-Man one of the most intricately layered in superhero storytelling today.
