Among the hordes of horrible hoods the Girls of Steels faced during their careers was two groups of gangs that repeatedly menaced their cities Chicago and Gotham. On Earth-One, it was the Council led by their mysterious leader the Director. On Earth-Two, it was an unnamed band led by Brain Wave, unrevealed at first. Additionally, the Council employed the behemoth bot known as Matrix-Prime while Brain Wave utilized gigantic robotic war-machines. Additionally, the telepathic powers of the Council's member Brains and Ms Mesmer* as well as BrainWave nearly broke down the Maidens of Steel. Almost, but not quite.
*Brains, Ms Mesmer, Bulldozer and Kong as well as the director were the counterparts of a gang that battled Earth-Two's Law's Legionnaires, which we'll consider in another post.
