"Last Charge: Finale"
*This. Is. It! It's an extra-sized anniversary celebration, and one of the biggest battles the Green Lantern Corps has ever fought to mark the occasion. John Stewart issues a dramatic order: no lethal force! The Green Lanterns need to prove they can keep law and order in the universe without killing. Elsewhere, Hal Jordan faces down Tomar-Tu, and looks to use the Darkstars' armor as a weapon against them-with some psychic help from Hector Hammond (who probably shouldn't be trusted). *Source: dccomics.com
