Hunter

Mobile Combat Doll, Model SP721 A combat-type ringleader of Sangvis Ferri answering directly to Intruder or Gager. Agile and intelligent, Hunter is most suitable for harassing and pursuing enemies in combat and is typically found in solo combat operations. Like most combat-type ringleaders, Hunter cannot command as many normal SF units as command-type ringleaders such as Scarecrow and Executioner, and so often works in tandem with them to unleash her higher potential.
