Helena Kosmatos was a new character named "Fury", created to replace the Golden Age Wonder Woman as Lyta Trevor's biological mother. She began appearing in Thomas' "Young All-Stars", a book set in World War II, and her backstory was revealed in "Secret Origins" #12. She was a Greek national who had learned her brother was co-operating with Italian Fascists who previously killed her father. When she confronted her brother with this revelation in front of their mother, it was too much for the widow to take and she died of an instant heart attack. Wishing revenge upon her brother, she was approached by Tisiphone, one of the Eumenides or Furies, who gave her a suit of magic armor, which increased her strength, speed and stamina. When angered, she became an avatar of Tisiphone, and it was in this state that she killed her brother.
