Forget everything you think you know about superhero origin stories. This is Invincible (2003), Robert Kirkman's groundbreaking, sprawling epic from Image Comics that follows teenager Mark Grayson. Mark seems like a normal kid, except for one small detail: his dad is Omni-Man, the most powerful superhero on Earth (and an alien Viltrumite). When Mark's own Viltrumite powers finally kick in, he's eager to follow in his father's footsteps, but what starts as a thrilling coming-of-age adventure quickly spirals into something far more brutal, complex, and unpredictable than he could ever imagine. Across its celebrated 144-issue run, Invincible delivers an unflinching look at the consequences of superhero battles, explores galaxy-spanning conflicts with the formidable Viltrumite Empire, and features some of the most shocking betrayals and character developments in comic history. Co-created with artists Cory Walker and Ryan Ottley, the series is infamous for its graphic violence that starkly contrasts its bright, classic art style, constantly challenging readers' expectations of what a superhero comic can be. If you're looking for a complete, epic saga filled with intense action, deep emotional stakes, and truly memorable characters, prepare to discover why Invincible became a phenomenon, long before its acclaimed Amazon Prime animated series.
