Хандзо Хаттори

Arguably the most famous ninja in history, the tales of Hattori Hanzo are still told in Japanese History books. He sent Gonosuke to kill Kanbei and retrieve the scroll, but when Iga is attacked by Oda's army, he allows Kanbei to bury the scroll and reveals he has his own copy, which passes onto Akechi Mitsuhide.
