From the Phantom Lady, a superheroines published in 1940's Quality Comics, sprung a sub-genre of dark damsels that have been replicated again... and again... and again. Always with similar elements that highlight brave brunettes battling bad guys.
While Charlton Comics presented Eve Eden as Nightshade, a survivor of a shadow dimension with the ability to turn herself into a shadow and teleport between dimensions. Later, Archie's Red Circle Comics revived the concept in Darkling, aka Darla Lang, a dimension traveling heroine whose powers derived from her cloak. Blending all these elements were filtered into the Blue Bulleteer, the World War II costumed alter ego of Laura Wright who acquired a similar cloak providing her abilities on par with her Sentinels of Justice compatriots when the debuted in 1983.
