HK-130
this was a model of small security droid manufactured on Balmorra. Resembling a tiny metal ball with small silver studs, the HK-130 was known as the "trouble seeker," since its primary mission was to search for potential criminals. It would scan each being it encountered and determine the being's level of threat. If the being resisted, or proved to be troublesome, the HK-130 could fire a powerful stun beam from one of the small silver studs.
