Paradise Lost

In the far future, the Earth-centered Galactic Alliance and the vast, alien Drule Supremacy are locked in an interstellar cold war. The discovery of an ancient war machine on a distant planet was supposed to tip the balance... but now the five explorers from Earth who found it have sworn allegiance to Planet Arus and to Voltron, the half-science, half-sorcery robotic titan who protects it. But when the Alliance takes matters into its own hands - first raiding Arus and stealing Voltron, then trying to replicate him for their military - the five members of the Voltron Force have no choice but to travel to Earth and reclaim what is theirs.
