The last 5 surviving Earths are slowly merging together in limbo as the Antimonitor attempts to destroy them using a solar machine inside his fortress in the antimatter universe, which is causing the merging. Harbinger and Pariah explain the old multiverse's origins and their roles in the Crisis. The heroes then stop the Antimonitor's machine, but at the cost of Supergirl sacrificing her life. She damages the Antimonitor's armor, forcing him to retreat while swearing vengeance. She is given a heroes' eulogy and private funeral by her cousin Superman (Earth-1). The earths are safe for now.
