Creation Story
Invincible is Robert Kirkman and Cory Walker’s creator-owned Image Comics superhero book, launched in January 2003 as part of Kirkman’s early indie-superhero publishing push. Kirkman had been writing Battle Pope and a handful of other Image books since 2000; Invincible was his attempt at a mainstream superhero book positioned alongside Marvel and DC flagship titles while operating in a creator-owned framework.
A cameo in Tech Jacket #1 (November 2002), Kirkman’s other Image launch of the period, introduced Mark Grayson ahead of the Invincible ongoing. The cameo is a setup piece; full character work lands in Invincible #1 (January 2003).
The book’s initial premise reads as a straightforward teen-superhero coming-of-age story: Mark Grayson discovers his powers (inherited from his Viltrumite father Omni-Man), takes the name Invincible, and begins balancing superhero work with high school. Cory Walker pencilled the first seven issues. Ryan Ottley took over with Invincible #8 and pencilled the majority of the 144-issue run that followed.
The Omni-Man reveal
Invincible #11 (April 2004) is the book’s defining moment and one of the most-reproduced sequences in modern comics. Mark’s father, Omni-Man, reveals he is not an Earthling hero but a Viltrumite conquistador sent decades earlier to prepare Earth for invasion by a galactic empire. Omni-Man beats Mark across the Pacific Ocean and the American Midwest, depicting violence at a scale and specificity that reframed what superhero comics could show.
The sequence reframes the entire book. What had appeared to be a coming-of-age story becomes a generational trauma narrative about a son discovering his father is a conquistador. Kirkman and Ottley spend the next 130-plus issues working through the consequences: Mark’s relationship with his family, his own slide toward Viltrumite imperialism, his eventual inheritance of the cosmic-scale role Omni-Man had prepared for him.
The Amazon adaptation
Invincible (2021) on Amazon Prime Video, developed by Kirkman with Simon Racioppa, adapted the comics faithfully. Steven Yeun voices Mark; J.K. Simmons voices Omni-Man. The season one finale recreates the Omni-Man reveal from Invincible #11 nearly panel-for-panel. The show has run three seasons through 2025 with a fourth confirmed for 2026.
The animated adaptation substantially expanded the character’s cultural visibility. Before 2021, Invincible was a critically-praised but commercially modest Image title. After 2021, the book is one of the most-collected modern Image series.
Collector context
Invincible #1 is the Invincible Image key. High-grade CGC 9.8 copies have crossed $1,000 at auction. First-print copies with the Cory Walker cover are the primary target. Prices have risen steadily since the 2021 Amazon launch.
Tech Jacket #1 (cameo) is a cheaper entry and a collector target for Invincible-specific completists. Invincible #11 (Omni-Man reveal) is a secondary key and one of the most-traded single issues from the run.
