Mark Grayson

Mark Grayson is a seemingly ordinary American teenager who discovers his father is Omni-Man, the world's most powerful superhero. When Mark's own Viltrumite heritage kicks in during adolescence, he develops incredible superpowers and takes up the heroic identity Invincible.

Mark Grayson is one of Image Comics' most enduring Modern Age heroes, making his debut in Erik Larsen's Savage Dragon #102 in 2002 before going on to headline his own long-running series and beyond. Over more than two decades — spanning Invincible, Savage Dragon, and Guarding the Globe — he's built an impressive 78-issue presence in the catalog, with three of those appearances earning key-issue status that collectors actively seek out. The company he keeps tells you everything about his pedigree: Dragon, Spawn, and ShadowHawk are among the titans sharing his pages, placing him squarely in the heart of Image's superhero universe. With a publishing history stretching from 2002 all the way to 2025, Mark Grayson is a genuinely generational figure in modern comics — the kind of character whose full run rewards the dedicated collector.
