In "Showcase" #94 (Sept. 1977), the Negative Spirit reappears when it possesses a Russian cosmonaut, Colonel Valentina Vostok, who becomes Negative Woman. Initially, Vostok could transform herself into a radio-energy form, possessing the same capabilities as Trainor's "partner". Later, as with Trainor, it would emerge from her leaving her physically weak but in control of it and requiring her to wear special bandages just as Trainor had. After Trainor's return, he gains strength from being in Vostok's presence and pleads with her to return the negative being to him. He later breaks Reactron out of Belle Reve Penitentiary and after fitting him with a regulator, uses him to successfully draw the negative being out of Vostok. During an encounter with Garguax, the negative being is disrupted and returns to Vostok, but saves Trainor and in the process heals Trainor completely removing all radioactivity from his body. After this, Trainor works with the Patrol in a support capacity but occasionally enters combat using high tech weaponry.
