After the death of Barry Allen, Snart retires from crime (she blames Allen himself for the Top's death, not his successor Wally West). She and her brother embark on a career as mercenaries, forming the Golden Snowball Recovery Company. Eventually she returns to crime, with a series of partners, all code-named "Chillblaine", whom she supplies with a replica of her brother's cold gun. The last of these was described as more intelligent and ruthless than his predecessors, and he kills Snart with the weapon she gave him, then holds Keystone for ransom with the aid of Doctor Polaris. Flash just barely manages to defeat them. Chillblaine is then killed by Captain Cold in retaliation. Her death has been a constant source of grief for her older brother.
