Jupiter's Legacy is an American superhero comic book series created by writer Mark Millar and artist Frank Quitely, published by Image Comics under the Millarworld imprint. The first issue debuted in 2013, launching a multi-volume narrative that follows the Union of Justice, a team of heroes who gained their powers during a mysterious island expedition in 1932. Decades later, their children struggle under the weight of an impossible legacy, especially as the original heroes’ rigid ideals clash with a changing world. Central to the story are brothers Sheldon and Walter Sampson, whose philosophical rift over how to use power mirrors larger debates about morality and society.
The series is Millar’s long-form meditation on superhero mythology, American exceptionalism, and economic anxiety, partly inspired by the 2008 financial crisis. Quitely’s detailed, expressive artwork and Peter Doherty’s colors give the book a grand, cinematic scale. The main storyline unfolds across multiple limited series, with prequels such as Jupiter’s Circle exploring the team’s early years in the 1950s and 1960s, and a sequel series, Jupiter’s Legacy: Requiem, continuing the saga decades later. Praised for its ambitious themes and visual storytelling, the comic has been a standout in Millar’s creator-owned catalogue.
