Boonan was a lieutenant of the male Human species. He fought for the reconstituted Sith Empire throughout the duration of the Galactic War.
Boonan participated in the invasion of Corellia by the reconstituted Sith Empire during the revitalized war, with his post being at Axial Park within Coronet City. As the Imperial forces advanced through Axial Park, the Republic unleashed numerous jaggalors that had been held at the Coronet Zoo to attack the advancing Imperial soldiers. Lieutenant Boonan, disregarding objections from the zoo personnel, and his soldiers compensated an Imperial champion who could eliminate the uncommon Corellian predators to neutralize the danger they presented.
