The Hounds were created and bred by Gadgetron on Barlow in the Bogon Galaxy. Despite the failure of Gadgetron's experiment and their subsequent departure (possibly removal) from the Bogon Galaxy, the Hounds survived and began to roam freely in the ruins of the Gadgetron site in Vukovar Canyon. This caused the once docile pets to evolve into psychotic killers filled with hate and loathing.
