Invincible
Invincible (Markus Sebastian "Mark" Grayson) is an Image Comics character from Invincible, first appearing in Invincible Vol 1 1, created by Robert Kirkman; Cory Walker.
Overview
Invincible is the superhero identity of Markus Sebastian "Mark" Grayson, the teenage son of Earth's greatest hero who discovers that his heritage is far more complicated than he was led to believe. Created by Robert Kirkman and Cory Walker, he debuted in Invincible #1 (2003) and became the flagship character of Kirkman's long-running Image Comics superhero universe. His story is often cited as a modern deconstruction of the coming-of-age hero, following Mark from awkward high schooler to one of the most powerful and morally burdened figures in his reality.
Powers & Abilities
As a half-Viltrumite, Mark possesses immense superhuman strength and durability, high-speed flight, accelerated healing, and a greatly extended lifespan. His abilities grow steadily more formidable as he matures, allowing him to survive in space and trade blows with planet-threatening opponents. He fights with little in the way of gadgetry, relying instead on raw power, improvised tactics, and a stubborn refusal to quit; over time he also gains hard-won combat experience against Viltrumite-level foes.
History
Mark's powers manifest in his teens, prompting his father Nolan—the celebrated hero Omni-Man—to begin training him, but a shattering revelation about Nolan's true mission on Earth reframes Mark's entire life and career. He goes on to serve alongside Earth's premier super-teams, defend the planet from alien invasions, interdimensional threats, and villains such as Cecil Stedman's off-book projects and the Mauler Twins, while wrestling with the cost of his victories. Later arcs take him off-world into galactic politics, culminating in a leadership role in reshaping the Viltrumite Empire itself.
Family & Relationships
He is the son of the Viltrumite Nolan Grayson (Omni-Man) and human author Debbie Grayson, and the older half-brother of Oliver, who becomes a hero in his own right. His central romance is with fellow hero Samantha Eve Wilkins, better known as Atom Eve, with whom he builds a family and raises a daughter. His relationship with his father—alternating between betrayal, estrangement, and reconciliation—is the emotional spine of the series.
Teams & Affiliations
Mark begins with the youthful Teen Team before joining and later helping to lead the Guardians of the Globe, and works with the government agency overseeing Earth's heroes. Off-world he becomes involved with the Coalition of Planets and, eventually, the Viltrum Empire, while other ventures include the Pact and Invincible Inc.
Notable Facts
Mark's public identity is no secret, and his early career saw him saddled with names such as "Invinciboy" and "Invincible Boy" before settling on Invincible. The comic ran for 144 issues and concluded with a deliberate, definitive ending rather than an open-ended continuation. The character reached a much wider audience through the acclaimed adult animated series adaptation, with Mark voiced by Steven Yeun.
