Since the dawn of the Silver Age, the Green Lantern Corps have presented one of the best concepts in comics as the original space-based corps of peacekeepers and law enforcement.

While there's typically one Green Lantern flying solo, the Corps has historically been at its best when there's a title that fleshes out the whole team.
