Green Lantern: War of the Green Lanterns

Geoff Johns and Doug Mahnke brought DC's cosmic saga to a head in this 2012 one-shot, which pits Hal Jordan, Guy Gardner, John Stewart, and Kyle Rayner against a corrupted Green Lantern Corps. The series sees the four Earth Lanterns forced to wield unfamiliar power rings as they battle an enemy who has turned their greatest weapon—the Central Power Battery—against them. This is a pivotal moment in the Johns era, closing a major story arc and reshaping the status quo for the Emerald Knights.
