Justice League: Origin is a six-issue comic book story arc written by Geoff Johns with art by Jim Lee, published by DC Comics in 2011. It served as the inaugural storyline for the second volume of the Justice League title, launching the company-wide New 52 reboot that reimagined the origins of its entire superhero universe. The story is set five years in the past of the newly established DC Universe continuity and depicts the first meeting and uneasy alliance of its most iconic heroes.
The narrative brings together Batman, Green Lantern, Superman, The Flash, Wonder Woman, Cyborg, and Aquaman (with Shazam appearing in later issues) as they are forced to set aside their mutual distrust to combat an invasion by the alien New God Darkseid and his Parademon forces from Apokolips. The arc is notable for redefining the team's founding lineup, prominently elevating Cyborg to a founding member status and establishing his origin as intrinsically linked to the invasion.
Justice League: Origin was a massive commercial success, with its first issue becoming one of the best-selling comics of the 21st century. It set the tone for the entire New 52 initiative, emphasizing a younger, more modern, and cinematic approach to DC's characters. The storyline's focus on large-scale action and character-driven conflict made it a natural choice for adaptation into other media, cementing its place as a key modern entry point for the Justice League mythos.
