Ninjitsu

Ninjitsu (properly, "Ninjutsu"), sometimes called ninpō, is a martial art, strategy, and tactic of unconventional warfare and guerrilla warfare as well as the art of espionage purportedly practiced by the ninjas.

In Mortal Kombat[]

In Mortal Kombat lore, the style was said to have been developed by Takeda when he split from the Lin Kuei to form a rival clan, the Shirai Ryu.

It is used as primary fighting style by Cyrax in Mortal Kombat: Deadly Alliance and Armageddon, and by Sektor in Mortal Kombat: Tournament Edition, because of him being a palette swap of Cyrax in that game.

In Deadly Alliance's Konquest mode, it is said that Ninjitsu is Cyrax's preferred fighting style among the many he learned with the Lin Kuei.

In Mortal Kombat X, one of Scorpion's character variations is Ninjutsu. This variation focuses on utilizing Scorpion's ninjitsu training over his demonic powers, which involves the use of his dual swords.

In Mortal Kombat 1, Kuai Liang as the new Scorpion & Smoke take up Ninjitsu.

Ninjitsu is one of the only fighting styles made up of several other fighting styles, like hand-to-hand combat and illusionary combat.
