This Kaminoan Mutating Virus was one of a series of
highly unethical and morally reprehensible scientific experiments conducted by the insane Taun Kiwi. This disease-like thingy was a sort of organo-synthetic agent that, after infecting its victims, turned their entire bodies into living computers. The unfortunate Kaminoans were then chopped-up for use as parts in the Living, Breathing, Talking, Flying, Hovering, Strafing, Bombing Republic Gunship then being developed for the Grand Army of the Republic.
The distribution of this virus was extremely restricted so as not to cause an outbreak, which was fortunate, as there was no cure.
