It is one of the three Silver Hawks available for Force's unnamed main character, the other two being model ZZ9X-0001 and model FRSA-6351. FFSA-0019 is Blue to distinguish it from these two other models (being red and green respectively). It was originally used during Darius II, making it possible that ZZ9X-0001 is the official name of the 2nd Silver-Hawk.
