The Harvesters were an extra-terrestrial threat that attacked countless homeworlds, and harvested their cores for advancement and survival. They did this with the Sphere's species, and other species as well. After that, the Sphere herself managed to rescue them in her own ship, and brought them to an unknown planet to teach them how to defeat the Harvesters once and for all. Together, they formed the Resistance.
Post-War of 1996 Edit
During the Congo Ground War, a distress message reached the Harvesters' home planet. The same Harvester Queen that sent her forces during the War of 1996 received the message, and left the Harvesters' homeworld, coming to Earth to avenge her lost colony.
