Specter-12 was the designated moniker for a supposed male humanoid. It was speculated that he had been a member of a clandestine government special operations group before his enlistment with the Specialists mercenary group. It was said that Specter-12's training was unprecedented during the period of the Galactic War. As commander of the Ghost Squad unit, he led a team of snipers and intelligence analysts, many of whom employed gear similar to that used by Imperial Intelligence operatives. He, along with the other members of the Specialists, met their death on the planet of Makeb.
