In ancient times, the Green Lantern Corps came across the planet Tchk-Tchk in Space Sector 407, which was home to an aggressive, insectoid race. After conquering their own planet, they began to spread to the rest of the galaxy, at which point the Guardians of the Universe decided to take action, sending the Green Lanterns to beat back the Tchk-Tchk and seal off their planet.
Unable to leave, the Tchk-Tchk quickly expended their food supply and began to die out. Realizing what was happening, they put their minds into their new invention, the Soul Jar, wherein they became a sort of hive mind. Once all the remaining minds had entered, they built themselves a new body and called themselves Legion.
Quickly discovering that he was powerful enough to break through the Lantern's barrier, it set out to exact revenge on the Guardians.
