Born a mutant after her parents were exposed to the radioactive fallout of Hiroshima, Tamara Kurtz became a mutant terrorist and was recruited into the Mutant Liberation Front
led by Stryfe
. Arrogant and overconfident, Kurtz and her M.L.F. teammates Sumo and Kamikaze were sent to Madripoor to oversee the distribution of a drug destined to contaminate the world's water supplies, but were opposed by Cable
's New Mutants
, Sunfire, and Wolverine
. After Stryfe's apparent death, the MLF continued under Wildside's leadership and Kurtz romanced him for a time. After attacking the Wakeman Oncological Research Center, the MLF reluctantly teamed with X-Force
in opposing Operation: Zero Tolerance forces and Kurtz was among those captured. Following Zero Tolerance's closure, Kurtz was remanded into S.H.I.E.L.D.
