Deathmaiden (no real name known) is a bioterrorist who appears to come out of hiding roughly every 20 years or so to devastate an area with a new plague, is seemingly stopped for good after a few years only to reappear when it is time again. Her appearances so far were in 1929, 1949, 1968 and 1989. Her attempt to wipe out New York in the early 1930s was stopped by Macrobiotic's grandmother. She killed Macrobiotic's father with a letterbomb, who had been working on stopping her attempt to wipe out central Africa with a plague.
