Synker were a predator from the planet Oxoor. They traveled with early Oxoorian colonists to other worlds and outlived their masters’ colonies, becoming wild and even more dangerous than on their homeworld. A fast-moving lizard that grew to be about three meters long, they hunted anything they could and were sometimes used by criminals as security. Klippy Resh fought against synker owned by slavers while trying to rescue the Wookiee Mawyrrlac.
