As a result of changes resulting from 1985-1986's Crisis on Infinite Earths event, some DC characters no longer ever existed (in continuity, that is) and others required some serious revisions to their origins / their relations to others.
One such character was Fury (Lyta Trevor), a member of the group Infinity Inc., who was originally conceived as the daughter of the Golden Age Wonder Woman and Golden Age Steve Trevor from Earth-2.
But with those two characters taken out of continuity when multiple Earths were merged into a single Earth, that meant Lyta Trevor needed a new background.
So, DC gave us Helena Kosmatos, who it appeared was going to be a replacement for Wonder Woman back in the days of World War II.

Helena's origin was revealed in Secret Origins #12 (March 1987).
But where the Golden Age Wonder Woman grew up on "Paradise Island", Helena's world was anything but a "paradise".
