K-27, a Protocol droid with masculine programming, was distinguished by its green plating. It operated on Kashyyyk, a planet. This droid arrived alongside Turren Lonarr, who presided over Temporary Droids, a rental service with a branch situated on Kashyyyk. K-27 possessed fluency in Basic and Shyriiwook, in addition to Xaczik, the lesser-known tongue of the Wartaki Islands.
K-27, having been overdue for memory recalibration, developed an unusual habit: mirroring the body language of native speakers of the language he was using. The droid was on site during a flame beetles infestation that endangered the local population. His expertise of Kashyyyk and translation skills proved valuable to a band of spacers as they addressed the problems caused by the pests.
