Superman, J'onn J'onzz, Hawkman, Hawkwoman, Dr. Fate, Captain Atom, Firestorm, and Green Lanterns Hal Jordan, Arisia, and Katma Tui Stewart have journeyed to the Procyon system to invade the Manhunters' home planet of Orinda. As they plot their strategy, Firestorm suddenly senses a call for help and flies off, with Captain Atom in pursuit (as seen in Firestorm (second series) #68). When the remaining heroes and heroines reach Orinda, they find the planet's surface utterly barren, but discover a system of underground corridors which constitute the Manhunters' base. The Green Lanterns are especially wary, as everything on the planet is colored yellow, and thus their power rings are useless. Instead of an enemy attack, however, the heroes encounter Gnort, the hope- lessly inept Green Lantern of Orinda's space sector. As Hal Jordan explains to the others, Gnort's uncle was a former GL who used his influence with the Guardians to have his nephew made a Corps member. The Guardians had assigned the bumbling Gnort to this sector because it was supposedly devoid of life, unaware of the presence of the Manhunters' hidden world. Having stumbled across Orinda by accident, Gnort has now been lost in its maze of tunnels for several months. Dr. Fate then senses the presence of their foes, so the super-heroes race to do battle, leaving the ineffectual Gnort behind on "guard duty". Hundreds of Manhunters are waiting to ambush the heroes, but thanks to a ruse engineered by J'onn J'onzz and Arisia, the Earth crusaders are able to take the androids by surprise. In less than a minute, their robotic enemies are smashed, and the team of past and present Justice League members and Green Lanterns stands victorious. The eight champions then enter what proves to be a Manhunter birthing chamber, where hundreds more of the robots lie in individual cubicles awaiting activation. Before this can be accomplished, Superman incinerates the inert androids with his heat vision. Far above them, the Highmaster, the supreme overlord of the Manhunters, comes to life and voices his displeasure at their actions. Rather than battle the heroes, however, the Highmaster simply departs to rebuild his planetary base elsewhere. Since it is his power which holds Orinda together, with his departure the planet begins to break apart. Superman gets his companions out of harm's way in time, and they are soon rejoined by Captain Atom and Firestorm, who have in turn been joined by Harbinger and Driq.
