FN-9999 or Nines was originally from the FN-crops of the First Order Stormtroopers. Nines was incredibly loyal to the First Order, to the point of executing civilians. He was part of a squad along with FN-2197. They served in many battles together, with FN-2187 being the most decorated member of the squad. After FN-2187's desertion, Nines battled with him on the planet Takodana. Though Nines managed to defeat FN-2187, now known as Finn, he was seriously injured by Han Solo using Chewbacca's bowcaster.
After his recovery, Nines, as punishment for his failure, was transferred to the Verlorenes Battalion.
