The universe was subjected to another crisis when the embodiment of death, Nekron, attacked using the Black Lantern Corps, an army of resurrected evil zombies wielding power rings. Every person who had ever been dead before was vulnerable to immediate zombification. Thawne's corpse returned as a member of the Black Lantern Corps, and called himself 'Black Flash'. He immediately sought out the Flash and began tormenting him to feed on his emotions.
Zoom returned with Black Lantern versions of Kid Flash and Solovar to battle Barry, Wally West, and Saint Walker. In the midst of the fight, Zoom's body suddenly became encased in ice, exactly at the moment when a cold grenade belonging to Captain Cold was set off in Iron Heights, which housed an incarcerated future version of Zoom. During the final battle with Nekron, Zoom was resurrected by a white light.
