According to DC continuity, before recruiting sentient beings to the Green Lantern Corps, the Guardians formed a robotic army called the Manhunters to maintain order across the universe. After eons of service, the renegade Guardian Krona altered their central programming, leading them to believe that the only way of maintaining order was to completely rid the universe of all known life. Sector 666 falls victim to this new philosophy when the Manhunters slaughter all but five of its inhabitants. The five survivors become known as the Five Inversions: a terrorist cell bent on the destruction of the Guardians of the Universe. They are incarcerated on the planet Ysmault, where one member, Atrocitus, is so consumed by his rage that it results in the formation of the first red power battery. Atrocitus had previously escaped at times, only to be defeated and returned. On one such occasion, he fatally attacked Green Lantern Abin Sur; but Atrocitus is returned to confinement by (then-Green Lantern) Sinestro. Atrocitus uses his power battery to bludgeon Qull and the other Inversions to death; however, he expresses more interest in exacting revenge on Sinestro.
