The Enforcer II was created by Hera to defeat Hercules. She was made of fire and so was very difficult to defeat. Hades sent the original Enforcer to assist Hercules in fighting her.
When the Enforcer II was hunting for Hercules she came across Iolaus. When he refused to tell her where Hercules was, she beat him badly. Iolaus survived long enough to warn Hercules about her and then he died. Later, the Enforcer II nearly killed Alcmene but the Enforcer saved her. When Hercules finally defeated her, Hades brought Iolaus back to life.
