Masamune Date

Masamune Date (伊達 政宗) is the young and ambitious ruler of the Date clan. He earned the nickname "One-Eyed Dragon" due to the removal of one of his eyes when he was eight. In Samurai Warriors, he is 14 years old, making him the youngest character in the game.

Samurai Warriors
Masamune is a rash yet intelligent leader who is boldly arrogant of his abilities. He deems others to be incompetent and often flings the line "Idiots!" or "Imbeciles!" in battle. In Samurai Warriors, he is a young boy in charge of an army who recklessly charges and interrupts many important battles (ie: Kawanakjima, Honnoji, ect.) by aiming to defeat both armies at once. Masamune fights with two boken or wooden training swords and can shoot laser beams from his eye patch. The closest he has to a friendship with the characters is him helping Keiji in his last stage. In Masamune's upper path ending, he conquers Japan and then sets his sights on Spain.

Like Oichi, Masumune's image matures in Samurai Warriors 2 but his personalty is kept intact. He is also armed with a saber and two pistols (a result of his friendliness with foreign merchants), and additionally refers to himself as the "Prince of Pistols". In his story, he is a submissive unit in the Toyotomi and later the Tokugawa forces. His force was principle in stopping Kanetsugu's army at Hasedo. After he defeats Yukimura at Osaka Castle, Masamune revives his pride and charges against Ieyasu in a coup d'état. For this battle, he also befriends Magoichi and they defeat Ieyasu at Mikatagahara. Once he becomes lord of the land, he expresses his wish to someday travel the world and expand his horizons.

His dream mode explores his participation at Sekigahara on the Eastern Army.

Warriors Orochi
In Warriors Orochi, Masamune is a loyal follower of Orochi. He has an adamant belief that his lord will inevitably conquer the land.

Kessen
Masamune makes an appearance in the first Kessen as the shaky ally for Ieyasu. He is famed for his prized calvary unit and his army of adept riflemen. In spite of their alliance, Masamune boldly declares that he will betray Ieyasu in the ally camp. If the Eastern forces performs poorly, he will live up to this promise. Otherwise, he makes a very solid yet reluctant unit.
