8613 Kanoka Disk Launcher Pack is a 6 piece BIONICLE set released in 2004. It contains two Kanoka Disks, a launcher for a Matoran, and two blue pins to attach the launcher to a Matoran or Toa. In the BIONICLE universe, Kanoka Disks are powered frisbee-like disks that are seen all over the city of Metru Nui, used in both sport and defense. They are produced in every Metru (city district), and whatever Metru they are made in determines their flight characteristics. Kanoka are also used as the material to make Kanohi masks.
