Sai blades are weapons used by a handful of ninja. Sai are a very specific type of dagger. Mileena is the traditional user of the Sai blades in the series; however, Li Mei borrowed them in Mortal Kombat: Deadly Alliance due to Mileena being absent in the game. Sareena also used the Sai in Mortal Kombat: Tournament Edition. Khameleon also uses them in Mortal Kombat Trilogy. Mileena uses the Sai as her handweapon, but also uses them as a projectile. The Sai are frequently included in her Fatalities as well.
