Working for Executor Sedriss QL during the Emperor's absence, he was sent to Nar Shaddaa with fellow darksider Zasm Katth. When they arrived, they attempted to enlist the aid of Boba Fett in tracking down the Millennium Falcon; Fett refused, after Kath and Fass demanded he work for them for free. They were also commanded to find and destroy the hidden Jedi Vima-Da-Boda, which they also failed to do as she was taken into Rebel protection by Princess Leia Organa Solo and Han Solo.
Bass and Kath chased the Millennium Falcon onboard their Star Destroyer Invincible. When they attempted a tractor beam lock, the Falcon maneuvered its way out and instead the beam locked onto Nar Shaddaa's control tower. The control tower was ripped off its foundation and skewered the Invincible. Fass, with the rest of the crew, was killed when the Star Destroyer crashed into structures protruding from Nar Shaddaa's surface.
