Final Crisis: Legion of 3 Worlds

Geoff Johns and George Pérez team up for this DC epic, tying together the far-flung corners of the Legion of Super-Heroes mythos. Published in 2009, this single oversized issue pits three distinct Legions from across time against a resurrected Superboy-Prime, as the fate of the 31st century hangs in the balance. A sprawling, Pérez-drawn love letter to the Legion's sprawling legacy, it serves as a pivotal moment in Johns' cosmic-era DC work.
