Francine Langstrom is the wife of Kirk Langstrom, the first Man-Bat. Francine was exposed to the serum when her father, Dr. March,
was working late in the lab one night, trying to perfect it. After she
startled her father, he dropped the vial that contained the serum,
shattering it on the floor. Helping clean up the mess, Francine was cut
by the glass and the serum entered her bloodstream, causing her to
transform into the Man-Bat.
