Hattori Hanzo

If Sarutobi Sasuke is the Miyamoto Musashi of Ninjas, then Hattori Hanzō was definitely the Yagyu Jubei of Ninjas.

Put it simply, Hanzo was the Ur Example of Ninja, although his actual profession was Samurai and he prefered to ride into battle with a spear. Born Hattori Masanari, he was loyal to his lord Tokugawa Ieyasu. He made his debut in the battle of Anegawa, at the tender age of 16, and earned himself the nickname "Devil Hanzo". He was a master of Iga ninjutsu. His biggest accomplishment was during Ieyasu's perilous journey crossing the Iga village after fleeing from Akechi Mitsuhide's forces after Mitsuhide killed Oda Nobunaga. Using his ninja connections, Hanzo proceeded to secure a path for Ieyasu to arrive safely in his domain. His cause of death is unclear, some say he was lured into a naval battle against Fuuma Kotarou and got his ship burnt down. However, this is heavily myth-based; historical records would say he died of sickness.

While his name isn't used as often as Sasuke's in the world of fiction, Hanzo remains a popular figurehead of Ninja these days.

Compare with Sarutobi Sasuke, Yagyu Jubei, also Oda Nobunaga.
