Groovy Girls of Gotham Week: Versus Mental Menaces

One day renowned professionals in their select fields. The next day, mental masterminds, thanks to mysterious alien rocks that imbue them with tremendous temporal traits. Geologist Kenneth Anderson and relic hunter Kirk Jason were two such men, living in Gotham City when they suddenly gained these grand gifts, which one used for good and the other for evil.

Anderson discovered an unusual rock, perhaps a meteorite, which when he experiments on it bestows upon the geologist tremendous mental powers. Transforming into the Annihilator, he retaliates against a city he feels fails to appreciate him. This attracts the attention of first Batgirl and then Supergirl, visiting the city on a interview tour for her alter ego's new show. Defeating the Girl of Steel and acquiring her power, he sought to transform Batgirl into his own mutated bride, but the gals double teamed on the madman and reversed his condition.

Jason one day awoke having discovered a piece of an ancient meteorite, which had previously been possessed by various men for untold centuries. Each was given cerebral capabilities such as telepathic and telekinetic which as the Immortal Man they used for justice. He also felt love for Helen Phelps, who had become acquainted with two previous Immortal Men. And like those individuals, Jason Kirk gave his life to save humanity from a threat to its safety, in this instance a gigantic subterranean beast.

Another pair of mental menaces whom the ladies battled continually were Doctor Voodoo and his evil mentor, and Doctor Tarr with his conspirator the Undertaker. While using medication to endure paranoid illusions upon Batgirl and Huntress, these devious doctors were defeated.
