Pateesa is an antagonist in Return of the Jedi. He is depicted as Jabba the Hutt's pet Rancor. He was kept under Jabba's palace as a pet. 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.
Jabba would often drop those who displeased him down into the Rancor's pit for them to be eaten, and did so with a disobedient slave dancer named Oola.
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. Pateesa ate Jubnuk, but Luke managed to outwit the savage beast by prying his mouth open with a bone, then throwing a skull to close the spiked gate on the Rancor's head, killing it. Malakili rushed out and mourned the creature's death with Giran.
