Kra, the King of the Robots, is exiled to Earth by the authorities of his planet. During his time in a robot prison, Kra studied the Challengers to develop a plan to defeat them. On Earth, Kra recruits three former foes of the Challengers, Multi-Man, Drabny, and the Volcano Man. The group then tries to divide and conquer by separating the Challs. Each villain is defeated by his opponent, and they are confined in specially constructed cells.
