The concept of the superhero and how it can connect to the real world is a common theme throughout Millar’s career and this somewhat recent introduction to his Millarworld, Jupiter’s Legacy, explores the concept of the families of superheroes and supervillains throughout time.
That is why the story goes through multiple generations and explores the stories and origins of these superheroes as if they were a modern day mythology, which is something that has been said a lot of times when regarding this medium: that superheroes are modern interpretations of mythology. And Millar connects this with the development of American society throughout the years, making for an interesting story and also giving us a deeper perception of what Millar understands of that country and their superheroes.
