Cullars are taking over one planet after another changing every alien child into a Cullar using science to do it. They haven't figured out how to change adults yet but their chief scientist Carpia, a hero to all Cullars, is still working on it. Jack, Whispy and Tonto on hiatus from earth's space force are trying to save as many alien kids as they can, hoping earth will join the fight, but it doesn't seem likely any time soon. Giagantheums are being attacked by the Cullars and everyone in the galaxy has faith they can defeat the them. But fear rises when it seems Giagantheum may fall. Trenor has had enough of waiting for others and decides to enlist the criminal underworld to try to save Giagantheum.
