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 is a gloomy and mysterious man who often compares himself to a shadow. He 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 his upper path ending, he kills Yukimura.

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.

Warriors Orochi
In both games, Hanzō is Ieyasu's steadfast servant in battle. He is available from the start.

Warriors Orochi 2
Hanzō begins as a member of the Shu army. In the Battle of Shi Ting, when Zuo Ci appears, he tells Hanzō that despite him being loyal first to his lord, that he must do what must be done to help the land. Next, in the Battle of Saika Village, Hanzō comes to assist Wei Yan in his fire attack and the two find respect in each other.

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. He is still a ninja and he isn't affiliated with the Tokugawa clan. He leads the best ninja unit in the game.
