Later, when Jedi Knight Luke Skywalker came to rescue Leia Organa, Han Solo, R2-D2, C-3PO, and Chewbacca from Jabba's clutches, Jabba dropped Luke and a Gamorrean guard named Jubnuk. Jabba would often drop those who displeased him down into the Rancor's pit for them to be eaten, and did so with a foolish disobedient slave dancer named Oola. It was given to Jabba by his adviser Bib Fortuna as a birthday present, and was looked after by a caretaker named Malakili, who took good care of the beast, causing the two to become fond and protective of one another. This, coupled with genetic mutation experiments performed by the Galactic Empire, cause Rancors to become an endangered species.ДЄ Rancor appears in Return of the Jedi, where a male named Pateesa was kept under Jabba the Hutt's palace as a pet. As such, hunters, poachers, and even warriors like the Jedi and Sith would seek out Rancors as opponents to train and claim as trophies after killing. Over the decades, Rancors were often confronted as powerful adversaries in combat. Those who were careful and kind enough to Rancors could even befriend them and use them as mounts, such as in the cases of the Witches of Dathomir and Maris Brood. Some Rancors even evolved to near human-level intelligence, including the ability to read and write.

In the wild, Rancors were intelligent and carnivorous animals that were fiercely protective of each other and their young.

However, when they were captured and sent as shipments to be pets on other planets, some ships crashed and introduced Rancors to planets like Felucia, Lehon, Carida, and Tatooine. Rancors are native to the planet Dathomir.
