The following year, DC Comics also published one extra book: JLA: Secret Origins. The work presented the origins of the four main characters already published in the previous books as well as the origins of other Justice League members: Green Lantern, Flash, Green Arrow, Black Canary, Martian Manhunter, Hawkman, Hawkgirl and Plastic Man. Every origin was present in two-pages layout based on Joe Shuster's origin of Superman from Action Comics #1.
