Francine Langstrom

Francine Lanstrom is the wife of Kirk Langstrom and aided in his attempts to synthesize a cure for his chronic deafness. She was seemingly killed by him when he spliced his DNA with that of a Vampire Bat and became Man-Bat. However, if Batman returns to Kirk's lab her body is missing and the words "Forever my love" are written on a broken television screen implying that Francine has been revived and turned into a similar creature as her husband.
