Eventually, the Diplomatic Corps (known as 'dishwashers') recalls most of the fleet back to the colonies in an effort to show the Geeks that they mean peace.
Much in the style of The Dirty Dozen this results in a high fatality rate and over the course of the series all of the V.C.s save Smith and Jupe are killed off.
Ultimately Smith, the sole member of the original V.C.s who remains fighting fit, leads a heroic attack on the Geek homeworld that ends the war.
A belligerent, persistent and aggressive species, they have risen to each challenge presented by their dozens of new homes, building stations, fortresses and cities wherever the space can be found, and even undergoing genetic treatment to better adapt to their worlds.
A great deal of animosity that shares elements of both racism and national pride exists between the colonists and the humans that chose to remain on Earth.
Smith, upon encountering the V.C.s, observed in his diary that his comrades were all 'half-castes', while his father, upon seeing Jupe on a vid-screen was surprised to see a 'real, live Jovian' and described him as an 'ugly-lookin' fish'.
Geeks possess a strange blend of reptilian and insectoid characteristics, perfectly adapted to life on their jungle homeworld.
They are several different kinds or castes of Geek: the most common serve as soldiers, appearing identical to human eyes but for a distinguishing pheromone.
A Geek general is recognisable by its swollen cranium and facial tentacles, suggesting that it and others like it are bred for heightened intelligence and advanced tactical planning.
Some Geeks are bred solely for the purpose of breeding; they are sent into ships as kamikaze troops, laying dozens of eggs at the moment of death in order to overwhelm the enemy with their young.
Contacted by "The Polity" during an extermination of the natives of 41 Hydra to assassinate a Geek ambassador to Earth, they were unsuccessful in their mission after the entire group perished and their leader killed.
