DZ-70
this was the model number of one of Arakyd's DZ-series of fugitive tracker droids. Similar in shape to the IT-series of interrogation droids, the DZ-70 was a repulsor-equipped sphere. It was programmed to single-mindedly track its target, regardless of environment, population, or physical obstacles,and was given a wide variety of sensor mechanisms to monitor a target's progress. A group of manipulator arms - borrowed by the Viper probe droids - hung below the DZ-70's body, and the droid was armed with a stun blaster and a laser cannon. The only drawback to the DZ-70 was it high maintenance. Many of these droids were placed aboard the Eye of Palpatine, and remained hidden until that ship became operational.
