Subject 4D668493X was a highly volatile bioengineered creature created by Imperial scientists. It was part of a program to create a creature that could aid Imperial officers in their efforts to track down and apprehend criminals.

Pale-skinned, 4D668493X possessed razor-sharp teeth and claws and a whiplike tail. In addition to giving the beast balance while scaling walls, the tail also served as a lethally efficient slicing weapon.

4D668493X escaped from the laboratory of its birth, and a bounty (disintegration only) was promptly placed on the abomination. It was believed to have stowed-away on a freighter bound for Tatooine, showing significant intelligence in choosing a ship scheduled for prompt departure, and significant patience in remaining hidden in the cargo hold during the entire trip.
