Baroness von Kampf was a Nazi spy who was active during World War II. She often clashed with the female costumed adventurer known as Miss Fury.
At some point, Erica met a man named Gary Hale, the former fiance of her arch-rival Miss Fury, and supposedly married him. Together, they had a son named Darron whom they both abandoned to Dr. Diman Saraf in Brazil.
While in Brazil, she was branded with a swastika in the middle of her forehead by Diego Manera. She has since attempted to hide the branding with her platinum blond hair.
