The Ninjato or Ninja Sword is a weapon generally portrayed as being used by ninjas in popular media despite having no real historical significance. It was straight, opposite to the curve of a regular Katana, and shorter to be easily brought during missions.
In the Mortal Kombat series, it is used as a weapon fighting style by three ninja characters: by Scorpion in Mortal Kombat: Deadly Alliance (and wields a special katana which looks like a ninja sword in Deception and Armageddon), by Noob Saibot in Mortal Kombat: Tournament Edition, because of him being a palette swap of Scorpion in that game, and by Chameleon in Mortal Kombat: Armageddon (though it is slightly different than Scorpion's Ninja Sword and its curved blade resembles a katana).
- Although Scorpion carries a long and short Ninja Sword on his back in MKDA, MKTE, MKD and MKA, the Ninja Sword he uses in battle appears to be a third sword, as the existing swords remain sheathed when he pulls the weapon out.
