However, the Tirolian homeworld was liberated by the Robotech Expeditionary Force. Unaware of these new Human invaders, the Regent decided to dispatch Senep to investigate the matter. Commander Senep suggested that he borrow troops and supplies from the garrison on Karbarra before proceeding which the Regent agreed. Commanding an Invid Flagship, he travelled to the Karbarran homeworld where his forces encountered the Farrago. Believing this to be Tesla's vessel, the Invid Brain did not order fire and Senep was ultimately killed when the Sentinels attacked and destroyed his ship.
