This is mostly a Green Lantern story* as Hal Jordan takes on aliens kidnapping the homeless and poor to colonize a desolate planet. Green Lantern defeats the kidnappers, but some of the victims decide to become colonists anyway. (This is a Denny O’Neil script, remember?)
*Green Arrow gets kidnapped himself in this issue by FIA agents, M. Helm and J. Bond. Subtle, huh?
