Fyzen Gor, a male gangster of the Pau'an species, is known for inventing the Phylanx Redux Transmitter. He was once a medical student at Prasteen Braak, the most prestigious medical institution located in Pau City on the planet Utapau. Together with Greesto Ftrak, another aspiring doctor from the same school, he had plans to establish their own surgical practice in Pau City's Preevow Sector.
Just a couple of weeks before their grand opening, a group of Pau'an gunmen stormed in and took both of them hostage, along with a class 1 medical droid. Gor, Ftrak, and the droid were then transported via speeder deep into the plains. When Ftrak inquired if their captors were affiliated with the Wandering Star, a notorious Pau'an gangster syndicate, Gor witnessed his friend being fatally shot in the chest. Approaching a roadblock, Gor and the others were ambushed by Utai raiders, who eliminated the Pau'ans. Gor seized a blaster and eliminated seven of the Utai, taking the last surviving raider as a prisoner. With Gor dragging his dying friend Ftrak, the droid transported the prisoner to a nearby cave. Ultimately, Gor experimented on his friend, who had since died in a coma, merging his flesh with the droid.
Over time, his fascination shifted towards droids and the fusion of organic and mechanical components. Drawing on the limited knowledge it possessed of Gor's research, the droid known as the Scourge sought to create cyborgs it could control to gain access to the Force. On two separate occasions, the crew of the Millennium Falcon made attempts to acquire the transmitter. The first involved Lando Calrissian and the droid L3-37, while the second saw Han Solo and Sana Starros swindle Gor out of the device. Following the fall of the Galactic Empire, Gor pursued Calrissian, threatening the destruction of Cloud City. Calrissian then enlisted Solo, and they assembled a team that included the Wookiee Chewbacca, the skilled young pilot Taka Jamoreesa, the Ugnaught technician Florx Biggles, and the Ewok slicer Peekpa to thwart Gor's plans.
After Calrissian destroyed the Phylanx Redux Transmitter, Gor fled. Solo killed him after a short fight during the escape from the Phylanx.
