Military action
The Manhunters rebel, starting with the brutal massacre of Sector 666.
Eventually, a flaw in the Manhunters’ programming leads them to believe that the only way to truly create order in the universe is to eradicate all life. They slaughter all but five living creatures in Sector 666 before the Guardians manage to shut them down.
Hounded by the Manhunters, a thief named Larfleeze flees to the planet Okaara, in the Vega System (Sector 2828), where he discovers the power of the Orange Lantern. The Guardians strike a deal with him, ceding authority over the system in return for his information about Sector 666.
