Uulshos justice droid

Uulshos Justice droids were assassin droids, presumably manufactured by Uulshos Manufacturing.

One of these droids was the Imperial assassin droid 2-124, that was captured by the Rebel Alliance. The droid escaped and killed a number of Rebel and New Republic officials over the years. It was placed in General Airen Cracken's confidential New Republic Intelligence brief listing the top fifty most dangerous beings to the New Republic.

Some Uulshos Justice droids joined with Force-sensitive Shard to form Iron Knights. The combination of a Jedi's use of the Force and an assassin droids skills made them deadly combatants.
