Lead by Hank Henshaw, the Manhunter robots have gathered Green Lanters that the Corps thought were dead, and are using them (and their power rings) to power a whole new evolution of robots. Hal Jordan has freed most of them, but when they last met, he was under the control of Parallax and had tried to kill them. So Hal finds himself trying to avoid the attacks of his fellow Lanterns, as well as those of Hank Henshaw and the Manhunters as he tries to atone for his actions as Parallax.
