Osh Scal was a male Polis Massan and the medical supply officer of the Polis Massa Medical Facility. He was one of few Polis Massans who were able to speak. In 19 BBY, only months following the birth of Luke and Leia as well as the death of Padmé Amidala at the facility, Obi-Wan Kenobi was disguised as Osh Scal in order to protect the information from the Imperial Inquisitor Sancor.
