Jos Beroya was a male Mandalorian warrior and the husband of Valk Beroya. Jos and his wife were members of Shae Vizla's clan, and he wore red and gray Mandalorian armor. Shortly before the Battle of Rishi in the Galactic War, a group of independent operatives came to the clan's enclave on Tracyn Island to speak with Vizla, and Jos and Valk fought the group as part of Vizla's "challenges." The pair were defeated, though not killed. Later, Jos Beroya joined Shae Vizla in her siege of the Eternal Empire's droid factory on Darvannis, leading his team inside the factory.
