Ubese are humanoid creatures that are primarily called on as mercenaries or bounty hunters. Normally, they are a very aggressive people. The Ubese's home world is unknown, and was supposedly heavily bombarded by Republic warships in ancient times. The Republic attacked in a preemptive strike due to aggressive weapon development programs on Ubese worlds. The bombardments destroyed the weapon stockpiles, destroying Uba I outright and poisoning Uba II, Uba III and Uba V. Only Uba IV remained somewhat viable, although the toxic atmosphere requires that the Ubese wear environment suits outdoors. Ubese tend to be very secretive, associating only within their own circles.

They have a very distinct hatred for Jedi, believing they destroyed their homeworld; thus they train with Cortosis weapons, items that can resist lightsabers. During the events of Knights of the Old Republic II: The Sith Lords, they were employed by an Exchange thug to kill the Jedi Exile. The typical Ubese wears a protective, airtight environment suit, and is armed with usually a double bladed vibro-sword. The armor they wear In Star Wars: Knights of the Old Republic is black with a little shine, their faces are not visible due to the helmets they prefer to wear.

Princess Leia was disguised as the Ubese bounty hunter Boushh in the beginning of Return of the Jedi.
