The stealthy assassins of Japan's feudal era, Ninjas were legendary warriors who inspired fear, awe, and respect.
Using the shadows to launch their sneak attacks against whomever they were paid to kill, their mastery of the art of assassination made them valuable to the samurai for espionage and political assassinations.
Their wide array of weapons allowed them to kill in many ways.
