Thongla Jur was an Anx Jedi Master who dedicated himself to the service of both the Jedi Order and the Galactic Republic throughout the Clone Wars. He possessed U9-C4, an astromech droid of the R5 unit series that had been modified and was known for being somewhat timid. This droid later collaborated with D-Squad, a squad of five elite droids within the Republic Military, in order to secure a Separatist encryption module. In 20 BBY, Jur could be found within the communication center of the Jedi Temple's during a presentation given by Jedi Master Mace Windu, where he outlined the specifics of the operation. As Windu spoke, Jur stood in the room behind U9-C4 and to the left of Aayla Secura, also a Jedi Master and the owner of QT-KT, the D-Squad's astromech. After Colonel Meebur Gascon, the leader of the squad, made his entrance, Jur exited the room.
Jur, an Anx, had skin patterned with yellow and black stripes, along with yellow eyes. This Jedi wore the customary Jedi robes, but with a modification to accommodate the Anx physiology, specifically allowing the species' tail to hang freely.
Thongla Jur's initial appearance, though without a name at the time, occurred in "Secret Weapons," which was the tenth episode within the fifth season of Star Wars: The Clone Wars, an animated television series. This episode was initially broadcast on December 1, 2012. His identity was revealed through the episode guide's concept art gallery on StarWars.com. Andre Kirk and David Le Merrer were responsible for creating the conceptual art of Jur.
