Invincible

Mark Grayson seemed like an ordinary teenager until his half-Viltrumite heritage awakened superhuman abilities inherited from his alien father, Omni-Man. Taking the name Invincible, he began his journey as a costumed hero in Robert Kirkman's acclaimed Image Comics series.

Few Modern Age characters have made the leap from surprise debut to full-fledged icon quite like Invincible, who first crashed onto the scene in Erik Larsen's Savage Dragon #102 in 2002 — a guest appearance that would prove to be the launching pad for one of Image Comics' most celebrated series. Over more than two decades, this character has built an impressive presence across Invincible, Savage Dragon, and Guarding the Globe, racking up 78 catalog appearances and three key issues that any serious collector will want on their shelf. The company is undeniably stellar — sharing pages with Dragon, Spawn, ShadowHawk, and other Image heavyweights — which speaks to just how deeply woven into the fabric of the Image Universe this character has become. If you're looking for a Modern Age hero with genuine staying power, a rich publication history, and a universe-spanning footprint, Invincible is absolutely worth your time.
