She was a member and presumed leader of the short lived super-villain group, The Terrifying Three. Other members included the originalQuarrel, and the Steel-Jacketed Man. At some point, she abandoned those villainous activities and pursued a successful career as a real-estate developer in Arizona.
When a bank in Scottsdale was robbed by somebody using a copy of her blade-bands, she went to Steeljack to get help. The investigation led them to the owner of T. J. Scoundrel's, a villain-themed restaurant. After the case broke, she took the evidence of her innocence, and put her lawyer on clearing Steeljack of charges that arose from the case.

Blade-bands: wrist-mounted weapons which generate energy blasts capable of cutting through bank vaults - or through Steeljack's skin. They are concealed under her gloves.
