Mu Na Ya was the name given to one of the exoboars in the litter of Sparky, a large exobar kept by the Ravagers pirate gang on the planet Rishi around the time of the Battle of Rishi in the Galactic War. When the Ravagers' former leader Ruugar hired offworlders to storm the Ravagers' base in Coratanni Town in order to kill his traitorous lieutenant Coratanni, the offworlders slew Mu Na Ya and the other exoboars in Sparky's litter that guarded the town's gate along with their mother.
