Mageddon

Mageddon is an ancient, cosmic weapon of apocalyptic scale, predating recorded history and drifting through space as an ultimate doomsday device capable of driving entire civilizations to self-destructive war. It resurfaced to threaten Earth, forcing the full Justice League to confront its near-unstoppable might.

Few threats in DC history have arrived with the sheer cosmic dread of Mageddon — a villain so massive in concept that Grant Morrison and Howard Porter unleashed it at the climax of their legendary JLA run in 1999. Emerging in the Modern Age as an ancient, apocalyptic force, Mageddon demanded the attention of the very best the DCU had to offer, sharing those pages with Wonder Woman, Kyle Rayner, The Flash, and Oracle herself. With only a handful of appearances and a key issue already to its name, Mageddon is the rare antagonist whose impact vastly outweighs its page count — a testament to Morrison's gift for conjuring threats that feel genuinely world-ending.
