History:
When Eve was a child, her mother revealed to Eve and her brother Larry that she was really a princess from the Land of Nightshades, and had come to Earth while escaping from the evil Incubus. Magda showed her children, who had inherited the ability to cross dimensions through shadows, how to use that power to travel to the Land of the Nightshades. While there, they were attacked by Incubus' flying warriors, who stabbed Magda, giving her a fatal wound. Larry was kidnapped, but Eve escaped by changing to shadow-form and transporting both herself and her mother back to Earth, where Magda died. Eve made a promise to her mother that she would return to rescue Larry someday.

After her mother's death and brother's disappearance, Eve's father moved them to Japan, where Eve began her self-imposed training by studying martial arts, becoming especially proficient in karate. She hid her training from her father, and after becoming the C.I.A. operative known as Nightshade, she continued to hide her double-life from him. To him, she is only a shallow jet-setter with no worries.

As Nightshade, she works for the C.I.A. as a "spy-smasher", exposing and apprehending foreign agents, and has often paired up with Captain Atom. Her ultimate goal is to reach a level of training where she can return to the Land of the Nightshades to rescue her brother.

Powers:
Nightshade can change to a semi-solide shadow-form, but must have some darkness to step into for the change. In this form, she is insubstantial to others, but she can touch them, using her martial arts skills to defeat her foes. The C.I.A. provides her with the specialized weapons in her arsenal:the "ebony bomb" has grenades, the "black light" beam to counter other light weapons or create a shadow for Nightshade, the "Black Cloud" cloaking device for her car, a motorized skateboard and a specialized hovercraft.
