Khiss was a massively built Dug mercenary, and also a comrade to Sebulba.
In the year 32 BBY, Khiss gave aid to Sebulba in a hunt for a number of Ghostling children; these children had previously escaped from Gardulla the Elder. Together with Sebulba, as well as Djas Puhr and Gondry, Khiss followed the children and their slave assistants, eventually finding them at Gardulla's pleasure gardens.
Pala diverted the Dug's attention, causing him to pursue her throughout the garden. She barely managed to evade the trap of a flesh-eating Deneba bush. Sadly, Khiss failed to see the peril until it was too late; he was consumed entirely by the bush before he even had a chance to cry out.
