believed that it was Kirk Langstrom who had become the Man-Bat. He flew out to Vegas and fought the She-Bat on the roof of a Vegas casino. After the initial fight, Batman deduced that his opponent was not Kirk Langstrom at all, but Francine. Finding Kirk, the two tracked Francine to a cave where Batman ensnared her with his batrope. He then administered the same antidote he had used in the past and Francine was once again cured. This treatment did not last long, however. A year later, a professor of Medieval history from Antioke University known as Baron Tyme used his sorcery to take control of Francine. Turning her back into the She-Bat, he had Francine attack and kill a former colleague of his named Professor Raymond Arthur. Kirk Langstrom became the Man-Bat again and used hypnosis to break Baron Tyme's hold over her. Kirk defeated Tyme and the sorcerer apparently died in his tower chamber when the room caught on fire. Batman consulted with Langstrom about his wife's condition and insisted that he give Francine a full blood transfusion. Kirk brought Francine to his home town of Chicago where she lived with him at the Lakeshore Manor Apartments. He kept a steady vigil over her condition and fortunately for them both, the blood transfusion appeared to have cured her. The Langstroms had two children, Rebecca and Aaron. While Rebecca was a normal human (excluding the times when her whole family was mutated into Man-Bats), Aaron was born a mutant bat-creature due to the serum in his parents' systems. She also served as the lead scientist for the Outsiders to help them with their missions. In 2011, "The New 52" rebooted the DC universe. Francine Langstrom is reimagined as a more villainous character. In this new timeline, she met Kirk as a research assistant and supposedly loved him for his conviction in developing the Man-Bat serum for curing deafness. When Kirk transformed into the Man-Bat to help cure the city of the Man-Bat epidemic, she decided to bring Kirk back so he could perfect the formula for its original purpose, then she would take the formula herself and transform into the She-Bat. With some reported deaths Kirk began to think that he lacked control over the beast, but he discovered that Francine's Man-Bat formula differentiated from his as the bat she used was a South American vampire bat.
