In her first appearance in DC Comics Bombshells, Dr. October is living in Leningrad, which was then 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.
