In 0 ABY, Bzorn discovered the Ionic Ring Ship created by Professor Renn Volz. The ship was built with the intent of stabilizing unstable atmospheres, but Bzorn saw its powers as capable of great destruction. He placed Volz under arrest, commandeered his ship, and took his daughter Mira as a hostage. Using her as leverage, Bzorn forced Volz to destroy the atmosphere of the Rebel planet Rion.
Soon after, he turned the ship's destructive power on the Volz's home planet of Little Kessel. However, unbeknownst to her father, Mira had escaped with the help of Han Solo, Chewbacca, and Luke Skywalker. After tracking them down, the three Rebel agents staged a daring rescue of Professor Volz. In the ensuing gun battle aboard the Ion Ring Ship's bridge, Bzorn was killed by friendly fire from one of his own stormtroopers.
