Streehn, a Kyuzo, held the position of deputy alongside his colleague Drego at Niima Outpost, situated on the planet of Jakku. Following the explosion of the banking vessel belonging to the Kubaz banker Rikard Lovas, Streehn and Drego were stationed at the office of their relative, Constable Zuvio, questioning individuals suspected of involvement in the blast.
The character of Streehn initially debuted in the short narrative "High Noon on Jakku," penned by Landry Q. Walker. He subsequently made an appearance as a non-prominent figure in the motion picture Star Wars: Episode VII The Force Awakens.
