Karal Kaar was a Twi'lek of the male variety, who possessed green skin and was in the employ of Aratech Droids Inc.. In 3956 BBY, his place of work was the Aratech Mercantile found on Dantooine. Jedi Master Nemo considered him to be a decent individual, despite his somewhat abrupt manner; they frequently played pazaak together in the wee hours of the morning.
Upon introduction, Karal Kaar pronounces his name 'Karal Karr.' Contrary to this, the official guide for the game depicts Kaar as an Ithorian character.
