Six heroes. One star-shaped alien menace. This is how legends are made.

When an alien being with cosmic powers attacks Earth, a new era of heroism is born. Starro the Conqueror forces the DC Universe's greatest champions to unite--launching the first Justice League and sparking a legacy of team-based storytelling still going strong today.

Packed with battles against villains like Despero, Felix Faust, and Kanjar Ro, this collection showcases the early years of the JLA: wild sci-fi plots, impossible odds, and the birth of super-team chemistry. It's the origin story for the world's greatest heroes, told with the imagination and excitement of comics' most influential era.

Brings together The Brave and the Bold #28-30, Justice League of America #1-19, and Mystery in Space #75.
