Superman: The Death and Return of Superman Omnibus #[nn]

In "Doomsday!", Superboy struggles to recover in the hospital when Maggie Sawyer recruits him to stop a secret alien cult using a building in Metropolis as a base. As the Bloodlines aliens spread their influence, D.C. Force and her Uncle Harry arrive—unbeknownst to her, the moment has come for her to awaken her long-suppressed powers. When the alien threat erupts, D.C. is bitten and transformed into the new Sparx, joining forces with Superboy in a desperate fight to stop the invasion. Written by Karl Kesel and Tom Grummett, with art by Tom Grummett and Ed Hannigan, and featuring a cover by Dan Jurgens, Jon Bogdanove, and Brett Breeding, this pivotal story is a standout in the Superman mythos.
