Pig-lizard Flu was a disease that was known to the galaxy by the time of the renewed war between the Sith Empire and the Galactic Republic. While contemplating the idea of creating his own virus in order to cure it and therefore become famous, the xenopathologist and combat medic Archiban Kimble—better known as Doc—considered combining Pig-lizard Flu with Gamorrean Mumps as a starting point. The flu was named after "pig-lizard," a derogatory term for a member of the porcine Gamorrean species.
