Kai was a male human who served as a commander in the Galactic Empire following the Battle of Yavin. He was stationed aboard an Imperial Star Destroyer that traveled to the remote Outer Rim world of Andelm IV. The local crime lord Jaum tried to sell dedlanite processed from Andelm beetles to him. However, the escaped slave miner Zarro and her ally Chewbacca told Kai that Jaum was a fraudster and a rebel spy. They also destroyed Jaum's dedlanite supplies, damaging Kai's destroyer in the process. Kai survived the bombing and imprisoned Jaum.
