Rancor

Rancors were large sentient creatures that could be found on Out Rim planets such as Dathomir, Tatooine, and Felucia. They were often tamed and kept by certain individuals in the galaxy as pets. On certain planets, such as Tatooine, Rancors were known to attack and raid certain inhabited areas of the planet, as seen during the Galactic Civil War, during which several rancor subspecies, such as the Shadow Rancor, Hunter Rancor, and Rage Rancors attacked bases under the control of both the Galactic Empire and the Alliance to Restore the Republic. One rancor on the planet Tatooine was captured and kept by Jabba the Hutt named Pateesa in his palace on Tatooine.
