K-OB7, also called Kayo, was a droid who entered into the service of the Bimm Sith adept Toki Tollivar shortly after the end of the Great Sith War. Kayo "helped" Tollivar by hiding the dead bodies of his strangle victims. Kayo and Tollivar eventually found themselves stranded aboard the luxury yacht Chancellor Fillorean until Zayne Carrick and the crew of the Hot Prospect recovered the lost vessel.
