Helen Alexandros was a ballet dancer who wasn't given a chance to perform in Swan Lake due to her unattractive appearance. She prayed to the Greek Gods for help, and the war god Ares answered her wishes and turned her into a beautiful creature. He told her she could stay as such under the conditions that she kills Wonder Woman. As the Silver Swan, Helen set out to defeat Wonder Woman, but ultimately met her own defeat, forcing Ares to strip her of her abilities. However, she soon regained her powers and fought Wonder Woman on subsequent occasions.
