undergoing the Siege of Leningrad. She meets Harley Quinn and other heroes when Raven magically transports Harley's circus into the city. Dr. October knows that Hugo Strange is now an agent of the Soviet government, and is working on various schemes to help lift the siege. She has been on the alert to any change in the laws of physics which would imply the use of magic, which is what drew her to the Harley group's arrival. Dr. October shows Isley how starvation has affected Leningrad, and Isley uses her powers to create a garden to feed the people of the city. Dr. October alerts Lois Lane and the others in Harley's group to Hugo Strange's experiments on political prisoners, particularly one bioweapon (the Bombshell Universe version of Power Girl) that appears at night to attack the Nazi army. She gives Lois and Andrea Grüener (the Bombshell Universe's female version of Dr. Benjamin Gruener—the villain known as The Reaper) a device to find this bioweapon. 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. Dr. October has a cameo in DC Comics Bombshells #100, appearing in Pamela Isley's garden as the Siege of Leningrad is
