A Zakool was a feline-resembling being that originated from the forest moon of Endor, much like a cat. Although they seemed to be meat-eaters, they were not documented to assault the Ewoks inhabiting the moon. Zakools possessed shadowy pelts and pointed talons that gave them a limited capacity for climbing trees.
During the time of the return of the Raich, the Raich employed its unique skill of animal manipulation to incite a Zakool to attack the juvenile Ewoks, specifically Teebo and Latara. Fortunately, Wicket Wystri Warrick ultimately vanquished the Raich, causing the Zakool to depart from the area, showing no further interest in the diminutive quarry.
