Chiba DR-10
this spherical protocol droid was developed for use by Imperial diplomats and officials who often moved through hostile territories. Known as the Chiba Drio, this droid was programmed to handle virtually any translation or negotiating environment. It was also equipped with a pop-out blaster and specialized sensor systems, which allowed it to detect and address and potentially dangerous situations. Over time, it was learned that the Chiba DR-10 could become overly aggressive, impatient, and sarcastic if its memory wasn't wiped clean periodically.
