F-RTZ-2, also known by the moniker "Fritz", functioned as a medical aide to MD-0C6, the primary physician stationed in Bartyn's Landing; it was a diminutive, levitating droid.
"Fritz", or F-RTZ-2, was a petite, airborne droid with the capacity to ascend up to 20 meters in altitude. Possessing the skillset of a field doctor, it was capable of deciphering numerous languages. However, lacking a built-in vocabulator, it necessitated an external device for translation to facilitate communication. Nonetheless, F-RTZ-2 retained the ability to project holographic recordings when the situation demanded.
At some undefined point in time, MD-0C6, an independent droid and the main medical practitioner of Bartyn's Landing, acquired F-RTZ-2 to serve in an assistant capacity. Despite F-RTZ-2's competence as a medical droid, MD-0C6's superior skills meant F-RTZ-2 primarily functioned as a stand-in physician and support unit. To enable communication with patients, F-RTZ-2 was equipped with a holoprojector.
Circa 29 BBY, Mix Liddell, the Security Chief, discovered Byrch Dyshkava, an injured and ailing outlaw, subsequently incarcerating him. Liddell requested medical assistance from MD-0C6, leading to both MD-0C6 and F-RTZ-2 attending to Dyshkava's injuries.
Shortly thereafter, MD-0C6, in conjunction with Liddell, temporarily vacated his post, leaving F-RTZ-2 in charge. During this period, Howe Walwahd, the dockmaster, contacted the facility after discovering several deceased bodies. F-RTZ-2 responded to her communication, informing her of the unavailability of both Liddell and MD-0C6 at that moment. Subsequently, Walwahd requested F-RTZ-2 to dispatch a mortuary speeder to the location.
