Hanzō Hattori

Hanzō Hattori (服部 半蔵) is the leader of the Iga clan who is loyal to Ieyasu Tokugawa. Like his common portrayal in fiction, he is a ninja rather than the historically accurate general. In the first game, he's 28 years old.

Samurai Warriors
Hanzō carries out his lord's will through covert activities. The first game emphasizes him assassinating Shingen during his lord's retreat at Mikatagahara. He shares a rivalry with Shingen's servants, Yukimura and Kunoichi; the latter is more of a competition to see who is the better ninja. He escorts his lord's escape through Iga and secretly infiltrates Ueda Castle for information. His final act is to assassinate Hideyori Toyotomi at Osaka.

In Samurai Warriors 2, he relatively remains the same except that he shares a rivalry with Kotaro and, to a lesser extent, Nene. As opposed to ending the Toyotomi line with Hideyori, he is ordered to stop it earlier with Hideyoshi's death.

Kessen
Although he is dead in the first Kessen (as the focus takes place after his death), his legacy continues in a young kunoichi named Okatsu. She is supposedly one of Hanzō's descendants. In the third game, he is a recruitable unit for Nobunaga's army.
