Koral was a soldier in the Robotech Expeditionary Force. He lead a plot to assassinate the Invid Regent who was visiting the SDF-3 at the time. His partners included Madok, Grell, and Kath. He and his team were eventually caught by Rebecca Nicks, after the Regent had been killed by Tesla (although the Regent he killed was not the true Regent, and the REF presumed the murder to have been committed by the Sentinels in general), and they were arrested for attempted assassination.
