Formerly a steelworker, Blanche Sitznski became a student at Taskmaster's Academy for criminals. She later took on the role as calisthenics instructor, responsible for training female criminals in hand-to-hand combat.

Some time later, Blanche was selected by executives in the Roxxon Oil Company to be a special agent in covert operations. At the Mutagenics Laboratory of Roxxon's subsidiary, the Brand Corporation, Sitznski was bioengineered to have various permanent serpentine adaptations.
