Atom receives a request to assist in the defeat of the ruler of Planet Batra and immediately travels to the location. Upon arrival, the dictator Gammer successfully lures Cobalt away from the group. Gammer then subjects Cobalt to a transformation, converting him into a robotic entity that is programmed to obey orders without question or hesitation. This betrayal forces Atom into a direct confrontation against his own brother, who has been stripped of his free will. The narrative centers on Atom's struggle to combat the mechanical version of his sibling while dealing with the immediate threat posed by the planet's tyrannical leader.
