The Guardians pursue the Renegades to a distant world known as Earth.

The Guardians contend with the monster Zod when the Renegades attack the Arctic island of Stolbovoy to obtain the energy source sorium.

Cy-Kill attacks the US military and uses the sorium to power a device that seizes control of the minds of every human on Earth.

The reunited Guardians must break Cy-Kill's hold over Earth in order to save GoBotron from a mass-produced fleet of Zods.
