After Supergirl (named Kara Starikov in this reality) liberates Power Girl from Hugo Strange's control, Dr. October helps Supergirl learn more about herself by describing the horrors the people of Leningrad have gone through. In turn, Supergirl reveals that she has been given a kryptonite knife. Dr. October declines to accept the knife, and instead leaves the group off to do more "humane mad sciencing". When the Kryptonian refugee Faora kills Raven's father, Trigon, Raven goes mad. Faora steals some of Raven's blood, transforming herself into the Bombshell version of Doomsday. Riding a firebird, Dr. October retrieves Varvara Dugina (Supergirl's adoptive mother) from the American refugee center where she's been hiding, Ipati Dugan (Supergirl's adoptive father) from the Soviet gulag where he was imprisoned, and Samuel Whitmore (biological father of Bombshell Universe's Stargirl) from his home in London. Ipati (transported by a zmei) and Varvara and Samuel (each riding a gamayun) arrive at the scene of battle. Dr. October orders the lesovik, Swamp Thing, to consume Doomsday. Supergirl and the Beefcake Superman destroy the kryptonite knife with their heat-vision, and Zatanna, John Constantine, and Raven to imbue the lesovik, Swamp Thing, with its radioactivity. To make the magic work, Varvara, Ipati, and Whitmore give up their lives, thus imprisoning Doomsday forever inside Swamp Thing.
