The Bio hound was a tracking construct which was made of malleable organic material allowing it to change shape depending on its environment which was received through internal receptors. It was produced by Biogears Unlimited for the Galactic Empire. It was semi-intelligent which allowed it to "adapt" its form when in the face of obstacles. When a target was chosen, the bio hound was 'programmed' with the genetic information of its intended target through the use of various bio material such as skin cells and hair. The bio hound was then let loose on the planet where it began to test the location for its target. Upon finding the target, the bio hound could either tag it with a liquid tracer that could be detected by Imperial agents or use acidic poisons to kill the target off. This made it an effective and devious assassination tool.
