is revealed that Francine only married Kirk to ensure the company that he would complete the serum and then have him killed so she could inherit a large sum of money. She developed her own serum after Kirk turned into the Man-Bat in order to keep her job. Kirk tried to help cure her, but she preferred her new form and attacked Kirk, but ultimately refused to kill him. Kirk combined the two serums in order to become a stronger beast and defeat Francine, and Francine mocked him by acknowledging that he could only beat her by becoming like her. She is later charged for the murders that she committed as the She-Bat. She is later released from Arkham by the Penguin and sent to attack Harley Quinn, demonstrating that she has much better control over her transformation than Kirk does. She injects the Man-Bat formula into Harley and her friend Tony to turn them into Man-Bats. However, Harley ultimately regains control over herself after Francine threatens Harley's friends and defeats the She-Bat.
