In Final Crisis: Rage of the Red Lanterns, Atrocitus is shown in a flashback as having apparently formed a central power battery by using the blood of the other Inversions in blood magic rituals. The battery stands before a great lake of blood from which he forms his red power ring (crystallized by his anger), as well as other rings and batteries used to form the Red Lantern Corps. Harnessing the red light of rage, he sends his rings out into the universe; however, upon accepting the rings, his recruits' hearts are rendered useless. Their blood spoils from within, forcing them to expel the violently flammable and corrosive material from their mouths. Additionally, the Red Lanterns are reduced to an almost animalistic state, with only Atrocitus appearing to be in full control of himself. Once Atrocitus assembles a sufficient force, he leads them on a mission to capture Sinestro (who is being transferred to Korugar for his execution). Coincidentally, the Sinestro Corps have similar plans and they launch an ambush on the Green Lantern escort to rescue their leader. In turn, both groups are then ambushed by the Red Lanterns, who are able to take Sinestro captive by slaughtering Green Lanterns and Sinestro Corpsmen alike.[9] Among the many Red Lanterns being seen by readers for the first time is one familiar face: former Green Lantern Laira. After being tried and found guilty for the murder of Amon Sur, she is expelled from the Green Lantern Corps. While being escorted away from Oa, her ship is attacked by a red power ring. It attaches itself to her, and provides her with a vehicle to achieve the vengeance against Sinestro that she seeks.[6]
